Furthermore, the automatic fishhook binding machine also includes a three-axis line-releasing mechanism, which is equipped with a line-releasing tube, a line-releasing stop clamp and a line-breaking shearing structure. The line-releasing stop clamp is used to clamp the fishing line to prevent external force from continuing to pull the fishing line out of the line-releasing tube; the line-breaking shearing structure is used to cut off the fishing line after the release; the line clamping and pulling-up mechanism is installed on the three-axis line-releasing mechanism.

Furthermore, the post-clamping pull-down mechanism comprises a pull-down linear drive mechanism, a horizontal telescopic drive mechanism installed at the output end of the pull-down linear drive mechanism, and a pull-down clamping head installed at the horizontal telescopic drive mechanism.

Furthermore, the two ends of the output rod of the pull-down linear drive mechanism are located at the opposite ends of the power source body of the pull-down linear drive mechanism, one end of the output rod is drive-connected to the horizontal telescopic drive mechanism, and the other end of the output rod is threadedly connected with a height adjustment limit head, and the height adjustment limit head is used to abut against the power source body of the pull-down linear drive mechanism.

Furthermore, the pull-down linear drive mechanism and the horizontal telescopic drive mechanism are both telescopic cylinders.

Furthermore, the rear pull-up mechanism after clamping the line is a pneumatic clamp, and the pull-down clamping head is a pneumatic clamp.

Furthermore, the inner side of the claw of the pneumatic clamp is covered with an anti-slip layer.

Furthermore, the wire clamping rear pull-up mechanism and the wire clamping rear pull-down mechanism are each provided with two groups; the two groups of the wire clamping rear pull-up mechanism and the two groups of the wire clamping rear pull-down mechanism correspond one to one respectively.

Fig. 1-Fig. 3 show a preferred embodiment of the fishhook automatic wire binding machine of the utility model, including a fishhook feeding mechanism 1, a transfer robot assembly 2 and a fishhook winding device 3. In this embodiment, in order to achieve the ultimate preferred purpose, that is, to complete the wire binding of one line and two hooks (one line has two ends respectively bound to a fishhook): the fishhook feeding mechanism 1 is provided with at least two groups, the transfer robot assembly 2 is provided with at least two groups, and the two groups of fishhook feeding mechanisms 1 and the two groups of transfer robot assemblies 2 correspond to each other one by one; the fishhook winding device 3 includes two groups of winding mechanisms 31 arranged opposite to each other.

The fishhook feeding mechanism 1 will be described first.

Referring to Fig. 4 to Fig. 8, the fishhook feeding mechanism 1 includes a fishhook guide structure 11 and a fishhook pushing structure 12. Referring to Fig. 5, the fishhook guide structure 11 includes a fishhook feeding support seat 111, a lifting compensation seat 112 and an elastic reset member 113. The lifting compensation seat 112 is installed on the fishhook feeding support seat 111, supported by the fishhook feeding support seat 111, and a first guide groove 114 is formed between the lifting compensation seat 112 and the fishhook feeding support seat 111. The elastic reset member 113 is connected to the lifting compensation seat 112, and is used to drive the lifting compensation seat 112 downward (or upward in an alternative solution) to approach the fishhook feeding support seat 111, so as to reduce the groove width of the first guide groove 114.

The fishhook pushing structure 12 can support the fishhook and drive the fishhook to pass through the first guide groove 114 .

When the fishhook feeding mechanism 1 is working, the vibrating plate 15 integrates the fishhook into the feeding guide rail 16 one by one, the fishhook is hung upside down on the feeding guide rail 16, and then slides down along the feeding guide rail 16 until the front end of the fishhook on the feeding guide rail 16 is blocked by the blocking block 17. Next, referring to the structure and working principle of the existing single fishhook distributing mechanism, for example, referring to the patent document with patent application number CN202310298827.4 which discloses the structure and working principle of the single fishhook distributing mechanism of the fishhook distributing and feeding device, the single fishhook is peeled off to the fishhook pushing structure 12. Subsequently, the fishhook pusher structure 12 feeds the fishhook into the first guide groove 114. If the cross-sectional diameter of the fishhook is too large (i.e., the fishhook is of larger size), the lifting and compensating seat 112 moves upward, thereby expanding the width of the first guide groove 114, so that the fishhook can enter the first guide groove 114. If the cross-sectional diameter of the fishhook is just equal to or slightly smaller than the first guide groove 114, the lifting and compensating seat 112 is not pushed and remains stationary. At this time, the fishhook is guided and clamped by the fishhook feeding support seat 111 and the lifting and compensating seat 112, so it is not easy to fall off. When the hook portion of the fishhook leaks out of the first guide groove 114, the fishhook pusher structure 12 stops moving forward, waiting for the unloading manipulator 21 (see FIG. 9 ) to clamp the hook portion of the fishhook and take the fishhook away. Moreover, after the fishhook enters the first guide groove 114, its state is switched from a vertical placement state to a horizontal placement state, thereby making it easier for the unloading robot 21 to extend horizontally to grab it, retract it, and then transport the fishhook away.

Obviously, by adding a fishhook guide structure 11 to the fishhook delivery path, and defining the first guide groove 114 between the fishhook feeding support seat 111 and the lifting compensation seat 112, under the compensation of the elastic reset member 113, the fishhook feeding support seat 111 and the lifting compensation seat 112 can approach or move away from each other, thereby guiding and clamping the fishhook, making it difficult for the fishhook to fall off. In addition, based on the fact that the fishhook feeding support seat 111 and the lifting compensation seat 112 can approach or move away from each other, the first guide groove 114 is also applicable to fishhook of various specifications, that is, fishhook of different cross-sectional diameters can be fed through the fishhook feeding mechanism 1, thereby improving the universality of the fishhook feeding mechanism 1.

In this embodiment, preferably, referring to Fig. 5 and Fig. 6, the fishhook guide structure 11 also includes a guide ramp seat 115, the guide ramp seat 115 is connected to the fishhook feeding support seat 111, the guide ramp seat 115 has a slope surface 1151, the slope surface 1151 and the first guide groove 114 are connected in sequence along the conveying direction of the fishhook, and the slope surface 1151 is used to guide the fishhook so that the fishhook is switched from a vertical hanging state to a horizontal placement state. In this way, when the fishhook is pushed forward by the fishhook pushing structure 12, it first passes through the slope surface 1151 of the guide ramp seat 115, and the tip or tail rod of the fishhook is lifted by the slope surface 1151, so that the fishhook gradually tilts until the tip or tail rod of the fishhook horizontally enters the first guide groove 114, and the hook portion of the fishhook is still pushed forward by the fishhook pushing structure 12. This arrangement allows the fishhook to be smoothly adjusted from a vertical position to a horizontal position during transportation, so that it can enter the first guide groove 114 more smoothly to further prevent the fishhook from falling off.

In this embodiment, referring to FIG. 7 and FIG. 8 , preferably, the fishhook feeding support seat 111 is connected with a first magnetic attraction structure 116, and the first magnetic attraction structure 116 is used to suck the fishhook tightly so as to remove the fishhook from the fishhook pushing structure 12. Among them, the first magnetic attraction structure 116 can be a natural magnet, or an artificial magnet, etc. When the fishhook pushing structure 12 feeds the fishhook into the first guide groove 114, the tip of the fishhook or the tail rod of the fishhook is sucked tightly by the first magnetic attraction structure 116, until the fishhook pushing structure 12 pushes the fishhook to the bent hook part of the fishhook leaking out of the first guide groove 114, the fishhook pushing structure 12 retreats. Based on the ability of the first magnetic attraction structure 116 to suck the fishhook tightly, the friction between the fishhook pushing structure 12 and the fishhook is not enough to drag the fishhook backward, so that the fishhook can be positioned at a specific position, so that the unloading manipulator 21 can accurately grab the fishhook.

In this embodiment, referring to FIG8 , in order to make the first magnetic structure 116 fully contact with the fishhook, thereby strengthening the adsorption force of the first magnetic structure 116 on the fishhook, preferably, the first magnetic structure 116 is embedded in the groove wall of the first guide groove 114. In this way, when the fishhook moves forward along the first guide groove 114, it will contact with the first magnetic structure 116 and be supported by the first magnetic structure 116, so that it can be stably attracted to prevent the fishhook from being dragged back.

In the present embodiment, referring to FIG. 5 and FIG. 8 , preferably, the fishhook guide structure 11 further comprises an auxiliary clamping structure 13, and the auxiliary clamping structure 13 and the fishhook feeding support seat 111 are arranged opposite to each other in the horizontal direction; the auxiliary clamping structure 13 comprises an auxiliary support 131 and a second magnetic structure 132; the auxiliary support 131 is provided with a second guide groove 1311, and the first guide groove 114 and the second guide groove 1311 extend in the same direction and are arranged opposite to each other in the horizontal direction; the second magnetic structure 132 is embedded in the groove wall of the second guide groove 1311. In this arrangement, when the fishhook is pushed into the first guide groove 114 by the fishhook pushing structure 12, if the tip of the fishhook is located in the first guide groove 114, the tail rod of the fishhook is located in the second guide groove 1311; if the tip of the fishhook is located in the second guide groove 1311, the tail rod of the fishhook is located in the first guide groove 114; the advantage of this arrangement is that the fishhook is supported by the fishhook pushing structure 12, the fishhook feeding support seat 111 and the auxiliary suction structure 13 to maintain a horizontal placement state, so it is more difficult to fall off. In addition, when the fishhook is pushed into place by the fishhook pushing structure 12, one of the tip of the fishhook and the tail rod of the fishhook is sucked by the first magnetic suction structure 116, and the other is sucked by the second magnetic suction structure 132, so it is more stable, that is, it can wait more steadily for the unloading robot 21 to take the fishhook away.

In this embodiment, referring to FIG. 5 and FIG. 8 , preferably, the fishhook feeding mechanism 1 further includes an anti-backward mechanism 14, the anti-backward mechanism 14 includes an anti-backward lifting drive mechanism 141, and an insertion rod 142 drivingly connected to the anti-backward lifting drive mechanism 141, the anti-backward lifting drive mechanism 141 can drive the insertion rod 142 to perform lifting and lowering movements, the insertion rod 142 is located just above the outlet of the first guide groove 114, and the insertion rod 142 is used to insert the hook portion of the fishhook to prevent the fishhook from being dragged back by the fishhook pushing structure 12. In this way, when the fishhook is pushed by the fishhook pushing structure 12 until the hook portion of the fishhook leaks out to just above the outlet of the first guide groove 114, the anti-backward lifting drive mechanism 141 will drive the insertion rod 142 to descend to prevent the fishhook from being dragged back by the fishhook pushing structure 12, so as to absolutely ensure that the fishhook can be reliably grasped by the manipulator. In addition, the fish hook is sucked tightly based on the first magnetic attraction structure 116 and the second magnetic attraction structure 132, so that the movement amplitude of the insertion rod 142 will not affect the fish hook and cause it to fall off.

In this embodiment, referring to FIG. 5 , preferably, the insertion rod 142 has a front claw 1421 and a rear claw 1422, and a receiving groove 1423 is formed between the front claw 1421 and the rear claw 1422. The front claw 1421 is used to insert the hook portion of the fishhook, and the receiving groove 1423 is used to receive the hook portion of the fishhook. In this way, when the insertion rod 142 is inserted into the hook portion of the fishhook, the insertion rod 142 and the feeding plate 122 of the fishhook pushing structure 12 are closed, thereby further preventing the fishhook from falling off unexpectedly.

In this embodiment, referring to FIG. 5 , preferably, the fishhook pushing structure 12 includes a feeding linear drive mechanism 121 and a feeding plate 122; the feeding plate 122 has a fishhook inverted hanging support portion 1221 and a fishhook pushing portion 1222, the fishhook inverted hanging support portion 1221 is used for the fishhook to hang upside down, and the fishhook pushing portion 1222 is used to abut and push the fishhook to transport the fishhook to the exit of the first guide groove 114. During operation, the feeding plate 122 retreats backward until the hook inverted support 1221 is located directly below the unloading guide rail 16, and then the blocking block 17 is driven horizontally away from the unloading guide rail 16 by an external linear motion driving source (such as a linear motor or a patent document with reference to patent application number CN202310298827.4 that discloses a hook distribution and feeding device) to release a hook and slide it onto the hook inverted support 1221. Then, the hook pusher 1222 moves forward, so that the hook falls into the pit enclosed by the hook pusher 1222 and the hook inverted support 1221, and is pushed forward by the hook pusher 1222. It can be understood that, as an alternative setting, the hook pusher structure 12 can be a combination of a linear drive mechanism and a horizontal moving rod, which can be moved by the horizontal moving rod, thereby dragging the hook to move horizontally.

In this embodiment, referring to FIG. 5 , preferably, the fishhook feeding support seat 111 includes a base 1111 and a second bolt 1112, the second bolt 1112 is threadedly connected to the base 1111, the elastic reset member 113 is a spring, the second bolt 1112 is passed through the spring, and the two ends of the spring respectively abut against the nut of the second bolt 1112 and the lifting compensation seat 112. In this arrangement, by adjusting the second bolt 1112, the squeezing force of the elastic reset member 113 on the lifting compensation seat 112 can be adjusted to ensure that the fishhook can enter the first guide groove 114 without affecting its forward movement.

In this embodiment, referring to FIG. 5 , preferably, the base 1111 is provided with an anti-swing positioning groove 11111, and the extending direction of the anti-swing positioning groove 11111 is parallel to the first guide groove 114; the lifting compensation seat 112 has a positioning bar 1121, and the positioning bar 1121 is embedded in the anti-swing positioning groove 11111. In this way, when the lifting compensation seat 112 is lifted, the lifting compensation seat 112 cannot swing left and right, so as to prevent the device from falling apart.

Next, the transfer robot assembly 2 with the function of detecting the absence of material will be described, referring to FIGS. 9 and 10 , which includes: a material unloading robot 21 , a transfer clamping mechanism 22 and a movable detection mechanism 23 .

9 and 10, the unloading manipulator 21 is used to remove the fishhook from the first guide slot 114 of the fishhook feeding mechanism 1 of the fishhook automatic wire binding machine. As an alternative, the unloading manipulator 21 can be a universal manipulator or the like.

Referring to Figures 9 and 10, the transfer clamping mechanism 22 includes an operating drive mechanism 221 and a transfer clamping manipulator 222. The transfer clamping manipulator 222 can clamp the fishhook from the clamping position of the unloading manipulator 21. The operating drive mechanism 221 is drivingly connected to the transfer clamping manipulator 222 to drive the transfer clamping manipulator 222 to deliver the fishhook to the winding device of the automatic fishhook binding machine. In other words, the transfer clamping mechanism 22 is used to obtain the fishhook from the unloading manipulator 21. Among them, the transfer clamping manipulator 222 can also be a universal manipulator, etc.

9 and 10 , the movable detection mechanism 23 includes a detection drive mechanism 231 and a proximity switch 232 . The detection drive mechanism 231 is connected to the proximity switch 232 and can drive the proximity switch 232 to approach or move away from the transfer clamping robot 222 , thereby detecting whether there is a fishhook at the transfer clamping robot 222 through the proximity switch 232 .

It is arranged in this way, that is, the detection drive mechanism 231 of the movable detection mechanism 23 drives the proximity switch 232 of the movable detection mechanism 23 to approach the transfer clamping manipulator 222, so as to detect whether the transfer clamping manipulator 222 has a fishhook, and if there is no material, the movement is stopped to avoid the fishhook automatic wire binding machine from producing defective products and improve the good product productivity of fishhook. In addition, based on the proximity switch 232, it is possible to detect whether the transfer clamping manipulator 222 has a fishhook at a close distance, and the detection accuracy is higher. In addition, the detection drive mechanism 231 of the movable detection mechanism 23 can drive the proximity switch 232 of the movable detection mechanism 23 away from the transfer clamping manipulator 222, so that the operation drive mechanism 221 of the transfer clamping mechanism 22 can normally drive the transfer clamping manipulator 222 to move without being interfered by the space of the proximity switch 232.

Referring to Figures 9 and 10, in this embodiment, preferably, the operation drive mechanism 221 is a first horizontal linear drive mechanism, and the detection drive mechanism 231 is a second horizontal linear drive mechanism. With this arrangement, the motion trajectories of the operation drive mechanism 221 and the detection drive mechanism 231 are both linear trajectories, and the range of motion space span is small, which avoids motion interference as much as possible. It can be understood that, as an alternative arrangement, the operation drive mechanism 221 and the detection drive mechanism 231 can both be a swing drive mechanism or a driving source of a special-shaped trajectory (such as a combination of a straight line and an arc), etc. Among them, the first linear horizontal drive mechanism can be a combination of a lead screw and a slider, a barless cylinder or an electric push rod, etc. And, the second linear horizontal drive mechanism can be a combination of a lead screw and a slider, a barless cylinder or an electric push rod, etc.

9 and 10, in this embodiment, in order to improve the precision of movement and detection accuracy, preferably, the movement directions of the first horizontal linear drive mechanism and the second horizontal linear drive mechanism are perpendicular to each other. In this way, the first horizontal linear drive mechanism and the second horizontal linear drive mechanism have a lower movement failure rate, and it is also more conducive to the proximity switch 232 to accurately determine whether there is a fishhook at the transfer clamping manipulator 222.

Referring to Fig. 9 and Fig. 10, in this embodiment, preferably, the unloading manipulator 21 comprises a rotary drive mechanism 211 and an unloading clamp 212, and the rotary drive mechanism 211 can drive the unloading clamp 212 to move in a vertical plane. In this way, the unloading manipulator 21 can grab the fishhook from a horizontal position to a vertical position, wherein the fishhook in the horizontal position is conducive to the unloading clamp 212 to stably grab the fishhook, and the fishhook in the vertical position is conducive to the winding device to wind the fishhook.

Referring to Figures 9 and 10, in the present embodiment, in order to precisely control the movement angle of the unloading jaw 212, preferably, the transfer robot assembly 2 with the function of detecting no material also includes a unloading frame 223, and the unloading frame 223 is provided with a horizontal position limit seat 2231 and a vertical position limit seat 2232, and the horizontal position limit seat 2231 and the vertical position limit seat 2232 are both located on the swing trajectory of the unloading jaw 212; when the unloading jaw 212 rotates to a horizontal position, the unloading jaw 212 abuts against the horizontal position limit seat 2231; when the unloading jaw 212 rotates to a vertical position, the unloading jaw 212 abuts against the vertical position limit seat 2232.

9 and 10, in this embodiment, in order to avoid rigid collision, preferably, the horizontal position limiting seat 2231 is connected with a first buffer head, and the vertical position limiting seat 2232 is connected with a second buffer head 22321. In this way, the first buffer head and the second buffer head 22321 are not only used to position the blanking clamp 212, but also used for buffering.

9 and 10, in this embodiment, in order to facilitate the installation and removal of the proximity switch 232, preferably, the movable detection mechanism 23 further includes a mounting sleeve 233, the detection drive mechanism 231 is drivingly connected to the mounting sleeve 233, and the proximity switch 232 is installed in the sleeve hole 2331 of the mounting sleeve 233. In this way, the proximity switch 232 is assembled in a plug-in manner, which is not only convenient for installation, but also convenient for disassembly and maintenance.

9 and 10 , in this embodiment, in order to improve the detection accuracy of the proximity switch 232, preferably, one end of the proximity switch 232 extends out of the sleeve hole 2331, and the other end of the proximity switch 232 is located in the sleeve hole 2331. In this arrangement, the end of the proximity switch 232 is located outside the sleeve hole 2331, so that the detection accuracy is higher.

9 and 10 , in this embodiment, during maintenance, in order to facilitate removal of the proximity switch 232 from the sleeve hole 2331 , preferably, the mounting sleeve 233 is provided with a hollow section 2332 , a portion of the sleeve hole 2331 is located in the hollow section 2332 , and the other end of the proximity switch 232 is located in the hollow section 2332 .

Referring to Fig. 9 and Fig. 10, in this embodiment, preferably, the movable detection mechanism 23 also includes a mounting frame 234, the mounting frame 234 is provided with a horizontal waist-shaped groove 2341, the detection drive mechanism 231 is inserted into the horizontal waist-shaped groove 2341, and is fixed to the mounting frame 234 by a locking nut 235; the length direction of the horizontal waist-shaped groove 2341 is parallel to the conveying direction of the first horizontal linear drive mechanism. In this way, the closest distance between the proximity switch 232 and the transfer clamping manipulator 222 can be adjusted by adjusting the relative position of the mounting frame 234 relative to the horizontal waist-shaped groove 2341 to ensure that the proximity switch 232 can work normally. In this way, according to the requirements of fish hooks of different specifications, the relative position of the proximity switch 232 can be appropriately adjusted.

Next, the description of the fishhook winding device 3 will be continued. Referring to Fig. 11 , the fishhook winding device 3 comprises two sets of winding mechanisms 31 arranged opposite to each other. The winding mechanism 31 comprises a rotating mechanism 311 , a fishhook clamping mechanism 312 and a winding support 313 .

The fishhook clamping mechanism 312 is installed on the rotating mechanism 311 and is driven to rotate by the rotating mechanism 311. The fishhook clamping mechanism 312 is used to clamp the fishhook so that the fishhook rotates with the rotating mechanism 311, thereby winding the fishing line on the fishhook.

The rotating mechanism 311 is connected to a fishing line end clamping mechanism 314, and the winding bracket 313 is installed on the rotating mechanism 311 to rotate with the rotating mechanism 311. The winding bracket 313 is provided with a guide rod 3131, and the guide rod 3131 is connected with a first telescopic elastic member 3132 and a compression block 3133, and the compression block 3133 is provided with a displacement compensation winding post 3134; the winding bracket 313 is also provided with a plurality of transfer winding posts (see FIG. 17, such as a first winding post 3135, a second winding post 3136, a third winding post 3137 and a fourth winding post 3138), wherein the fourth winding post 3138 is located below the winding bracket 313, and FIG. 17 is required for easy understanding; when the fishing line is wound around the fishhook, the displacement compensation winding post 3134 moves along the axial direction of the guide rod 3131 and compresses the first telescopic elastic member 3132.

During operation, the two groups of hook clamping mechanisms 312 of the winding mechanisms 31 clamp a hook respectively, and then enter the wiring link. One end of the fishing line is sent to the fishing line end clamping mechanism 314 of one of the winding mechanisms 31 through the existing mature fishing line three-axis pay-off mechanism 7 (i.e., X-axis, Y-axis, and Z-axis), and then the fishing line is wound around the transfer winding column and the mobile displacement compensation winding column 3134 until the fishing line is wound to the fishing line end clamping mechanism 314 of the other winding mechanism 31 and clamped by it, and then the fishing line is cut so that the cut fishing line is a whole line and both ends are clamped by the fishing line end clamping mechanism 314 of one of the winding mechanisms 31. Then, the rotating mechanisms 311 of the two sets of winding mechanisms 31 rotate synchronously and in opposite directions, so that the displacement compensation winding column 3134 moves along the axial direction of the guide rod 3131 and compresses the first telescopic elastic member 3132, so that the fish hook winds the fishing line around itself (i.e., the line is tied); in this way, the two fish hooks are tied synchronously and are located at both ends of the same fishing line.

Preferably, referring to Figure 11, the fishhook clamping mechanism 312 includes a fishhook clamping support seat 3121, two fishhook clamping heads 3122 installed on the fishhook clamping support seat 3121, a reset elastic component installed on the fishhook clamping support seat 3121 and used to drive the two fishhook clamping heads 3122 to move closer to each other, and a swing cam 3123 installed on the fishhook clamping support seat 3121. The swing cam 3123 is provided with a rotating head, and the opposite sides of the rotating head are respectively abutted against one of the fishhook clamping heads 3122; when one of the opposite sides of the rotating head abuts against the rotating heads of the two fishhook clamping heads 3122, the two fishhook clamping heads 3122 are tightly attached to each other to clamp the fishhook together; when the other opposite sides of the rotating head abut against the two fishhook clamping heads 3122, the two fishhook clamping heads 3122 are separated from each other so that the fishhook can be inserted or taken out. This arrangement allows the two fishhook clamping heads 3122 to clamp the fishhook by means of two return springs of the return elastic assembly. When the cam swings, the rotating head rotates, thereby driving the two clamping heads away from each other and opening.

Referring to FIG. 11 , the fishing line end clamping mechanism 314 of the patent document with patent application number CN202320606179.X is as follows: the fishing line end clamping mechanism 314 comprises a fishing line end clamping support seat 3141, a movable clamping seat 3142, and a second telescopic elastic member; the fishing line end clamping support seat 3141 is provided with an avoidance through hole 31411, the movable clamping seat 3142 is penetrated through the avoidance through hole 31411, and one end of the movable clamping seat 3142 has a size larger than the avoidance through hole 31 411, the other end of the movable clamping seat 3142 has a pressure head, the end line clamping head 31421 and the pressure head are located at the opposite ends of the avoidance through hole 31411, one end of the second telescopic elastic member is in contact with the fishing line end clamping support seat 3141, and the other end is squeezed by the pressure head, the second telescopic elastic member is used to force the end line clamping head 31421 to approach the fishing line end clamping support seat 3141, so as to clamp the end of the fishing line together with the fishing line end clamping support seat 3141.

Next, the description of the fishing line tensioning device of the automatic hook binding machine with the function of detecting whether the fishing line is tightened is continued. Referring to FIG. 12 , the coarse pulling mechanism 4 includes a coarse lifting and lowering driving mechanism 41, a pressure sensor 42 and a wire support frame 43. The coarse lifting and lowering driving mechanism 41 is driven by the pressure sensor 42 to connect the wire support frame 43. The wire support frame 43 is located above the two winding mechanisms 31 and is used to support the middle section of the fishing line; the coarse lifting and lowering driving mechanism 41 is used to drive the wire support frame 43 to rise, so as to drive the fishing line to tighten upward, so that the fishing line is in a taut state after the winding is completed. It should be noted that the wire support frame 43 is not only used for the fishing line to cross, so that the fishing line can cross from the left winding mechanism 31 to the right winding mechanism 31, but also after the winding is completed, the fishing line is pulled up, so that the hanging fishing line is tightened to a taut state, so as to facilitate the later fine pulling mechanism 6 to better tie the end of the fishing line to the fishhook tightly. Moreover, in order to facilitate the unified judgment of whether the fishing line is neatly reeled in, the coarse lifting and lowering drive mechanism 41 is driven by the pressure sensor 42 to connect the line support frame 43. Only when the pressure sensor 42 is within the set interval value, it means that the fishing line is neatly collected and not broken, thereby ensuring that the finished fish hook is a good product when it is taken away.

In addition, it should be noted that after the fine pulling mechanism 6 acts on the fish hook, the coarse pulling mechanism 4 continues to pull the fishing line.

Referring to FIG. 12 , preferably, the rough lifting and lowering driving mechanism 41 includes a vertically placed vertical cylinder 411, a lifting slider 412 drivingly connected to the vertical cylinder 411, a supporting fixture 413 installed on the lifting slider 412, and a pressure sensor 42 installed on the supporting fixture 413. The vertical cylinder 411 is sensitive in action and meets the requirements of fishhook production efficiency. It can be understood that as a replaceable setting method, an existing mature product such as an electric push rod can also be used to replace the combination of the vertical cylinder 411 and the lifting slider 412.

Referring to Fig. 12, in order to improve the stability of the rough lifting and lowering driving mechanism 41, preferably, the supporting tool 413 includes a wire pulling plate 4131 and a wire pulling rib plate 4132, the wire pulling plate 4131 is connected to the lifting slider 412, the bottom of the wire pulling rib plate 4132 is connected to the wire pulling plate 4131, and the side wall of the wire pulling rib plate 4132 is connected to the lifting slider 412. In this way, in the process of tightening the fishing line, the pressure sensor 42 is prevented from tilting as much as possible.

Referring to Fig. 12, in order to further improve the stability of the rough lifting and lowering driving mechanism 41, the lifting slider 412 has a vertical through hole 4121, and the vertical cylinder 411 is connected with a guide plate 414, which is inserted into the vertical through hole 4121 and guides the lifting slider 412. In this arrangement, the guide plate 414 supports the slider and the supporting fixture 413, thereby further strengthening the lifting line stability of the supporting fixture 413.

12, the line support frame 43 includes a line dragging body 431 and line hanging rods 432 connected to opposite sides of the line dragging body 431. In this arrangement, only two line hanging rods 432 are needed to realize the long-distance crossing of the fishing line, and the line support frame 43 is more lightweight, and is convenient for the fishing line to be hung, and it is convenient to take away the finished fish hooks later.

12 , in order to facilitate the falling off of the fishing line during the pulling process, an anti-line-off limiting outer protrusion 4321 is provided on the end of the line hanging rod 432 away from the towing line body 431 , and the two anti-line-off limiting outer protrusions 4321 protrude in directions away from each other.

12, in order to improve the installation convenience of the tow line body 431 and the wire hanging rod 432, the tow line body 431 is provided with a horizontal long groove 4311, and the end of the wire hanging rod 432 close to the tow line body 431 is a flat head structure and is embedded in the horizontal long groove 4311. In this way, when the wire hanging rod 432 is bent, it can be taken out horizontally and replaced.

12 , in order to facilitate the assembly between the tow line body 431 and the wire hanging rod 432 , the tow line body 431 is provided with a horizontal waist-shaped through hole 4312 , and the flat head structure is connected with an adjusting screw, which is passed through the horizontal waist-shaped through hole 4312 .

Referring to Fig. 12, in order to ensure the working sensitivity of the pressure sensor 42, the lifting drive mechanism is located at the top of the pressure sensor 42, and the wire support frame 43 is located at the bottom of the pressure sensor 42. In this arrangement, the initial gravity of the wire support frame 43 has been detected by the pressure sensor 42, and during the wire pulling process, the left winding mechanism 31 and the right winding mechanism 31 are pulled against each other, which also makes the pulling force of the pressure sensor 42 centered downward, thereby further ensuring the accuracy of the pressure test.

The lifting drive mechanism is connected to the pressure sensor 42 via a first fastener, and the wire support frame 43 is connected to the pressure sensor 42 via a second fastener. It can be understood that, as an alternative arrangement, the first fastener and the second fastener can be replaced by riveting, mortise and tenon connection, etc.

Next, the anti-deviation power module for the automatic fishing line binding machine will be described.

Referring to FIG. 14 , the anti-biased power module includes an auxiliary module group 5. The auxiliary module group 5 includes a base plate 57, a first linear push mechanism 51 and a second linear push mechanism 52; one of the first linear push mechanism 51 and the base plate 57 is provided with a first positioning groove 571, and the other is provided with a first positioning convex strip engaged with the first positioning groove 571; the first linear push mechanism 51 is connected with a first push rod 53, and the first push rod 53 is used to abut against the swing cam 3123 and push the swing cam 3123 to rotate; one of the second linear push mechanism 52 and the base plate 57 is provided with a second positioning groove 572, and the other is provided with a second positioning convex strip engaged with the second positioning groove 572; the second linear push mechanism 52 is connected with a second push rod 54, and the second push rod 54 is used to abut against the pressure receiving head. In this way, most or most of the components that need linear motion are first positioned on the same base plate 57 to ensure the relative motion parallelism of each linear power component so that they can accurately cooperate with each other. It should be noted that if the components of the linear motion are directly fixed to the base plate 57 with screws, the error will inevitably be magnified when the components are extended over a long distance due to the slight deviation between the threads.

The auxiliary module group 5 also includes an auxiliary winding structure 55; the auxiliary winding structure 55 is provided with at least two groups, and the two groups of auxiliary winding structures 55 correspond to one of the winding mechanisms 31. The auxiliary winding structure 55 includes a first linear drive mechanism 551 and a line hanging needle 552 driven and connected to the first linear drive mechanism 551, and the first linear drive mechanism 551 is used to drive the line hanging needle 552 to extend to the top of the fishhook clamping mechanism 312, and for the fishing line of the winding mechanism 31 to be wound; one of the first linear drive mechanism 551 and the bottom plate 57 of the auxiliary winding structure 55 is provided with a third positioning groove 573, and the other is provided with a third positioning convex strip engaged with the third positioning groove 573. This arrangement is based on the fact that the line hanging needle 552 is a relatively important component in the winding process, and therefore it is necessary to ensure its accuracy when extending.

The auxiliary module group 5 also includes a tail wire cutting structure 56, which includes a second linear drive mechanism 561 and a cutter 562 driven and connected to the second linear drive mechanism 561, and the cutter 562 is used to cut off the residual wire at the movable clamping seat 3142; one of the tail wire cutting structure 56 and the bottom plate 57 is provided with a fourth positioning groove, and the other is provided with a fourth positioning convex strip engaged with the fourth positioning groove. Among them, as a preferred mode of this product, in this embodiment, the first linear drive mechanism 551 is provided with an L-shaped positioning step 5511, and the tail wire cutting structure 56 is installed on the L-shaped positioning step 5511, that is, there is no need to set a fourth positioning groove and a fourth positioning convex strip.

Preferably, the first positioning groove 571, the second positioning groove 572, the third positioning groove 573 and the fourth positioning groove are parallel to each other, and the first positioning groove 571, the second positioning groove 572, the third positioning groove 573 and the fourth positioning groove are all arranged on the bottom plate 57 to reduce the difficulty of processing.

Referring to FIG. 14 , in order to fully utilize the height space, preferably, the first linear pushing mechanism 51 , the second linear pushing mechanism 52 , the auxiliary winding structure 55 and the tail wire cutting structure 56 are distributed at intervals in the horizontal direction.

14 , in order to ensure working efficiency, the first linear pushing mechanism 51 , the second linear pushing mechanism 52 , the first linear driving mechanism 551 of the auxiliary winding structure 55 and the second linear driving mechanism 561 of the tail wire cutting structure 56 are all telescopic cylinders.

To facilitate installation and disassembly, the first linear pushing mechanism 51, the second linear pushing mechanism 52, the first linear driving mechanism 551 of the auxiliary winding structure 55 and the second linear driving mechanism 561 of the tail wire cutting structure 56 are respectively fixed to the base plate 57 by one or more third fasteners.

Next, the description of the fishing line tensioning device will be continued.

Referring to Figures 14 to 16, the fishhook tensioning device includes a fishhook winding device 3 and a fine pulling mechanism 6. The fine pulling mechanism 6 includes a rear pull-up mechanism 61 and a rear pull-down mechanism 62. The rear pull-up mechanism 61 can extend to the top of the fishhook winding device 3 and clamp the fishing line, and the rear pull-down mechanism 62 can extend and clamp the end of the fishing line; the rear pull-up mechanism 61 can pull up the fishing line, and the rear pull-down mechanism 62 is used to pull down the fishing line. In this way, the rear pull-up mechanism 61 extends and clamps the middle section of the fishing line near the fishhook winding device 3, and then cooperates with the rear pull-down mechanism 62 to pull the fishing line at the same time, so that the deep binding of the fishing line and the fishhook can be completed directly in a mechanized way.

Referring to FIG. 16 , preferably, after the fishing line is wound, the line hanging needle 552 is essentially inserted into a loop of the fishing line. If the fishing line is released, it is easy to reverse the spiral movement, resulting in loosening. Therefore, in order to avoid the above problems, the precision pulling mechanism 6 also includes a line loosening prevention mechanism 63. The line loosening prevention mechanism 63 (see FIG. 11 ) includes a horizontal linear clamping mechanism 631 and a buffer clamping head 632 driven and connected to the horizontal linear clamping mechanism 631. The buffer clamping head 632 is used to squeeze the fishing line wound on the fish hook to prevent the fishing line wound on the fish hook from loosening. Based on the limited pressure provided by the buffer clamping head 632, the precision pulling mechanism 6 is allowed to pull and tie the fishing line on the fish hook during this period.

Referring to FIG. 16 , the automatic hook wire binding machine further includes a three-axis wire release mechanism 7, which is equipped with a wire release tube 71, a wire release stopper 72, and a wire breaking shearing structure 73. The wire release stopper 72 is used to clamp the fishing line to prevent the external force from continuing to pull the fishing line out of the wire release tube 71; the wire breaking shearing structure 73 is used to cut the fishing line after the wire release is completed. Importantly, in order to save the number of power structures, the clamping back pull-up mechanism 61 is installed on the three-axis wire release mechanism 7. This arrangement uses the existing three-axis wire release mechanism 7 to drive the clamping back pull-up mechanism 61.

At this time, referring to FIG. 14 , preferably, the clamping back pull-down mechanism 62 includes a pull-down linear drive mechanism 621, a horizontal telescopic drive mechanism 622 installed at the output end of the pull-down linear drive mechanism 621, and a pull-down clamping head 623 installed at the horizontal telescopic drive mechanism 622. In other words, with the three-axis driving function of the three-axis pay-off mechanism 7, the clamping back pull-up mechanism 61 only needs to have a horizontal movement function to avoid structural interference. The clamping back pull-down mechanism 62 needs to have a lifting function and a horizontal movement function.

Referring to FIG. 15 , different fish hooks require different lifting forces, so that the lifting stroke required by the pull-down mechanism 62 after the line clamp is different. Therefore, preferably, the two ends of the output rod 6211 of the pull-down linear drive mechanism 621 are located at the opposite ends of the power source body 6212 of the pull-down linear drive mechanism 621, one end of the output rod 6211 is connected to the horizontal telescopic drive mechanism 622, and the other end of the output rod 6211 is threadedly connected with a height adjustment limit head 6213, and the height adjustment limit head 6213 is used to abut against the power source body 6212 of the pull-down linear drive mechanism 621. In this way, by rotating the height adjustment limit head 6213, the rising height of the pull-down clamping head 623 can be adjusted.

Preferably, in order to ensure the operation efficiency, the pull-down linear drive mechanism 621 and the horizontal telescopic drive mechanism 622 are both telescopic cylinders. Also, the clamping rear pull-up mechanism 61 is a pneumatic clamping claw, and the pull-down clamping head 623 is a pneumatic clamping claw.

Preferably, in order to prevent the fishing line from slipping, the inner side of the claw of the pneumatic clamp is covered with an anti-slip layer.

In order to correspond to the two groups of winding mechanisms 31, two groups of the rear-clamping pull-up mechanism 61 and the rear-clamping pull-down mechanism 62 are each provided; the two groups of the rear-clamping pull-up mechanism 61 and the two groups of the rear-clamping pull-down mechanism 62 correspond to each other one by one.

The following describes the wire binding method of the automatic wire binding machine for fish hooks, see Figure 17:

Two winding brackets 313 are located between two hanging needles 552; one of the transfer winding poles of the winding mechanism 31 is the first winding pole 3135, one of the transfer winding poles is the second winding pole 3136, one of the transfer winding poles is the third winding pole 3137, and one of the winding poles is the fourth winding pole 3138; the reverse direction of the first horizontal direction is defined as the second horizontal direction;

When wiring, the two winding brackets 313 are arranged opposite to each other along the first horizontal direction; the relative relationship between one of the hanging needles 552 and one of the winding brackets 313 is as follows: the hanging needle 552, the first winding post 3135, and the second winding post 3136 are arranged in sequence along the first horizontal direction; the end line clamping head 31421 of the fishing line end clamping mechanism 314 is located directly below the first spacing area between the hanging needle 552 and the first winding post 3135; the displacement compensation winding post 3134 is located below (diagonally below or directly below) the second spacing area between the first winding post 3135 and the second winding post 3136; the third winding post 3137 and the fourth winding post 3138 are located below the displacement compensation winding post 3134, and are arranged in sequence along the second horizontal direction;

The wire binding method for the automatic wire binding machine for fish hooks also includes the following winding steps:

Step 1: One end of the fishing line is clamped by one of the end line clamping heads 31421; the other end of the fishing line goes around the hanging needle 552 upwards along the second horizontal direction, then goes around the first winding post 3135 downwards along the first horizontal direction, then goes around the displacement compensation winding post upwards along the first horizontal direction, then goes around the second winding post 3136 downwards along the first horizontal direction, then goes around the third winding post 3137 downwards along the second horizontal direction, then goes around the fourth winding post 3138 upwards along the first horizontal direction, then goes through the first spacing area upwards, and then extends along the first horizontal direction to be supported by the wire support frame 43;

The second step: then pass downward through the first spacing area of another winding bracket 313, then go downward and around the fourth winding post 3138 of another winding bracket 313 along the second horizontal direction, then go upward around the third winding post 3137 of another winding bracket 313, then go toward the first horizontal direction and downward around the second winding post 3136 of another winding bracket 313, then go along the first horizontal direction and upward around the displacement compensation winding post 3134 of another winding bracket 313, then go toward the first horizontal direction and downward around the first winding post 3135 of another winding bracket 313, then go along the first horizontal direction and downward around the hanging needle 552 of another auxiliary winding structure 55, then extend downward and along the second horizontal direction into the other end wire clamping head 31421 and be clamped.

When winding the line, the line hanging needle 552 remains stationary, and one of the two winding brackets 313 rotates clockwise and the other rotates counterclockwise, so that the two fish hooks are respectively wound on the two ends of the fishing line. In this way, the binding of the fishing line can be completed in an automated manner, and the fish hooks are not easy to fall off.

Preferably, in order to prevent the fishing line from falling off, in the first step, after the other end of the fishing line passes around the fourth winding post 3138 upwards and along the first horizontal direction, it first extends in the first horizontal direction directly below the winding bracket 313, then turns upward into the lead-in groove of the winding bracket 313, then passes upward through the first spacing area, and then extends in the first horizontal direction to be supported by the wire support 43. And, in the second step, after the other end of the fishing line passes downwards through the first spacing area of another winding bracket 313, it first enters the lead-in groove of the winding bracket 313 downwards, then turns to the first horizontal direction directly below the winding bracket 313 and then passes around the fourth winding post 3138 of another winding bracket 313 downwards and along the second horizontal direction.

It should be noted that all the clamping heads of the present application can be pneumatic or electric clamps, etc., and all kinds of linear motion parts can be electric push rods, cylinders, etc., which only need to be purchased.

At the end of the winding, at this time, the fishing line is wound around each intermediate winding post (for example, the first winding post 3135, the second winding post 3136, the third winding post 3137 and the fourth winding post 3138). In order to enable the fine pulling mechanism 6 to clamp the middle section of the fishing line and lift it upward: preferably, referring to FIG. 11, the winding bracket 313 includes a first frame 3139, a second frame 31310 and a rear push plate, the first frame 3139 is fixed to the rotating mechanism 311, and the intermediate winding post is arranged on the second frame 313 10, and movably plugged into the first frame 3139, the second frame 31310 is connected with a push column 31311, the push column 31311 is also movably plugged into the first frame 3139, the push column 31311 is sleeved with a horizontal push back reset spring 31312, the two ends of the horizontal push back reset spring 31312 respectively abut the ends of the first frame 3139 and the push column, so as to drive the second frame 31310 close to the first frame 3139, so that the transfer winding column extends out for the fishing line to be wound. The push back plate is connected with a linear push mechanism, after the fishing line is wound, the linear push mechanism drives the push back plate to squeeze the push column to compress the horizontal push back reset spring 31312, thereby driving the transfer winding column backward, and then releasing all the fishing line, so that the fine pulling mechanism 6 can further tie the fishing line to the fishhook. In addition, it is supplemented that before the transfer winding column retreats, the buffer pressing head 632 needs to press the fishing line onto the hanging needle 552. And, after the fishing line is pulled by the fine pulling mechanism 6, it is returned to the hanging needle 552. Finally, the finished fishhook is taken away by the unloading equipment on the gantry 8.
