In the above embodiment, the X-axis linear module 4 , the rotary terminal device 2 and the plastic shell fixing device 3 are installed on the frame 1 , and the rotary terminal device 2 and the plastic shell fixing device 3 are all located below the X-axis linear module 4 . The X-axis linear module 4 drives the Y-axis linear module 5 to move along the X-axis direction, and the Z-axis linear module 6 drives the terminal positioning and clamping device 3 to move along the Z-axis direction. The tension detection device 7 includes a mobile base 71 and a sliding detection device 72. The sliding detection device 72 can be slidably or relatively statically installed on the mobile base 71. The Y-axis linear module 5 drives the mobile base 71 along the Y-axis direction. To move, the Z-axis linear module 6 is installed on the sliding detection device 72 .

In the above embodiments, the rotary terminal device 2 includes a pneumatic gripper 21 and a driving motor 22 . The pneumatic gripper 21 is connected with the output shaft of the drive motor 22 . Before the terminal positioning and clamping device 3 clamps the terminal A, the wire on the terminal A is clamped by the pneumatic clamping claw 21, and the driving motor 22 drives the pneumatic clamping clamp 21 to rotate, so that the terminal A is rotated to the angle of docking with the plastic shell B Afterwards, the terminal positioning and clamping device 3 is driven to clamp the terminal A.

In the above embodiment, after the Y-axis linear module 5 drives the terminal positioning and clamping device 3 to clamp the terminal A, and before the terminal A is inserted into the plastic case B along the positive direction of the Y-axis, the sliding detection device 72 touches the moving base 71 While relatively static, the terminal A is inserted into the plastic case B through mutual cooperation among the X-axis linear module 4 , the Y-axis linear module 5 and the Z-axis linear module 6 . After the terminal A is inserted into the plastic case B along the Y-axis positive direction, the Y-axis linear module 5 drives the terminal positioning and clamping device 3 to clamp the wire on the terminal A and apply force along the Y-axis negative direction. At this time, the Z-axis linear module 6 applies a thrust in the negative direction of the Y-axis to the sliding detection device 72. After the sliding detection device 72 is under pressure, if the sliding detection device 72 and the mobile base 71 slide relative to each other, the product will be detected. is qualified. If the sliding detection device 72 and the mobile base 71 are relatively stationary, the sliding detection device 72 and the mobile base 71 will move together along the negative direction of the Y axis. At this time, the terminal A will be pulled out from the plastic shell B, then The product was found to be defective.

Specifically, please refer to FIG. 3 and FIG. 4 together. The sliding detection device 72 includes a sliding seat 721 , a low-friction cylinder 722 , a pushing cylinder 723 , a displacement sensor 724 and a limit rod 725 . The sliding seat 721 is fixedly connected with the terminal positioning and clamping device 3, and the sliding seat 721 can be slidably installed on the mobile base 71. One end of the mobile base 71 is fixed with a baffle 711, and the end of the sliding seat 721 close to the baffle 711 is fixed. There are skateboards 726. The end of the stop bar 725 away from the baffle plate 711 is a larger head end with a diameter. The tail end of the stop bar 725 is fixed on the baffle plate 711. Lean against the head end of the limit rod 725 , therefore, the slide plate 726 can move between the head end and the tail end of the limit rod 725 . The low-friction cylinder 722 and the push cylinder 723 are installed on the opposite end of the slide seat 721 away from the baffle plate 711. The piston rod of the low-friction cylinder 722 can extend and press the mobile base 71. The pressure value of the low-friction cylinder 722 can be set to Check the pressure threshold. When the piston rods of the low-friction cylinder 722 and the push cylinder 723 are stretched out, they can both abut against the moving base 71 , so that the slide plate 726 can be pulled to the head end of the limiting rod 725 to stop. At this time, the sliding seat 721 and the mobile base 71 are relatively fixed and stationary, the displacement sensor 724 is installed on the sliding seat 721 , and its sensing rod contacts the baffle plate 711 .

Before the terminal A is inserted into the plastic case B along the positive direction of the Y-axis, the piston rods of the low-friction cylinder 722 and the push cylinder 723 abut against the moving base 71 . At this time, the pressure value that the piston rod of the low-friction cylinder 722 can withstand is the set detection pressure threshold (the detection pressure threshold is set according to the qualified requirements of the detection product), and the slide plate 726 is against the limit rod 725. At the head end, the sensing rod of the displacement sensor 724 contacts the baffle plate 711 , and the sliding seat 721 and the moving base 71 are relatively stationary. After the terminal A is inserted into the plastic case B along the positive direction of the Y axis, the piston rod of the driving cylinder 723 shrinks, while the piston rod of the low-friction cylinder 722 maintains the test pressure value and continues to push against the mobile base 71 . The Y-axis linear module 5 drives the terminal positioning and clamping device 3 to clamp the wire on the terminal A to apply force along the negative direction of the Y-axis, and the piston rod of the low-friction cylinder 722 on the slide seat 721 receives a thrust along the negative direction of the Y-axis. When the sliding seat 721 and the mobile base 71 slide relative to each other, that is, the sliding seat 721 moves in the positive direction of the Y-axis relative to the mobile base 71, and the mobile base 71 moves in the negative direction of the Y-axis relative to the sliding seat 721. The pressure in the negative direction of the Y-axis received by 721 is greater than the set detection pressure threshold that the piston rod of the low-friction cylinder 722 can withstand, and the piston rod of the low-friction cylinder 722 will shrink, indicating that terminal A is inserted into the plastic shell After B is completed, the tensile force that the wire on terminal A can withstand has met the qualification requirements of the product, and the finished product is qualified, that is, terminal A is plugged into place after being inserted into plastic shell B. At this time, the sensing rod of the displacement sensor 724 shrinks against the baffle plate 711. When the displacement sensor 724 senses a change in displacement, it transmits a feedback signal to the terminal positioning and clamping device 3, and the terminal positioning and clamping device 3 releases the terminal A. wire. When the sliding seat 721 and the moving base 71 are relatively stationary, that is, the sliding seat 721 and the moving base 71 move along the negative direction of the Y-axis, it means that the pressure on the positive direction of the Y-axis on the sliding seat 721 is smaller than that of the low-friction cylinder 722 The set detection pressure threshold, the piston rod of the low-friction cylinder 722 will not shrink, indicating that after the terminal A is inserted into the rubber case B, the tensile force that the wire on the terminal A can withstand does not meet the qualified requirements of the product, and the production is completed. The finished product is unqualified, that is, the insertion of terminal A into the plastic shell B is not in place. At this time, the sensing rod of the displacement sensor 724 does not shrink against the baffle plate 711. When the displacement sensor 724 does not sense a change in displacement, the displacement sensor 724 will not transmit the feedback signal to the terminal positioning and clamping device 3, and the terminal positioning clamp The holding device 3 will continue to hold the wire on the terminal A and continue to move along the negative direction of the Y axis, and the terminal A will be pulled out from the plastic shell B.

It is installed on the Z-axis moving slide table 341, and the fixed clip 345 and the positioning cylinder 343 are fixedly installed on the Z-axis moving slide table 341. The fixing clip 345 has a first notch 3450 for holding the terminal A. As shown in FIG. One end of the rotating clamp 346 is rotatably installed on the Z-axis sliding block 342, and is fixedly connected with one end of the rotating connecting rod 344. The other end of the rotating clamp 346 is a free end, and there is a hole for connecting with the first notch on the end. 3450 cooperates with the second notch 3460 for clamping and positioning the terminal A. The other end of the rotating connecting rod 344 is connected with the piston rod of the positioning cylinder 343, and the positioning cylinder 343 drives the rotating clamp 346 to rotate, and can drive the Z-axis sliding block 342 to move along the Z-axis direction.

Specifically, the original state of the piston rod of the positioning cylinder 343 is an extended state, and the fixed clip 345 forms a certain angle with the rotating clip 346. First, the piston rod of the positioning cylinder 343 is driven to shrink, thereby driving the rotating connecting rod 344 to drive the rotation. The clip 346 moves closer to the fixed clip 345 until the rotating clip 346 can no longer rotate to clamp and fix the terminal A between the fixed clip 345 and the rotating clip 346, realizing the left and right positioning of the terminal A. Then continue to drive the piston rod of the positioning cylinder 343 to shrink, so that the Z-axis sliding block 342 moves along the positive direction of the Z-axis, and then drives the rotating clamp 346 to move upward, thereby positioning and clamping the terminal A between the first notch 3450 and the second notch 3460 In the formed space, the up and down positioning of terminal A is completed so far. The automatic positioning terminal device 34 realizes the positioning and clamping of the terminal A in four directions, left, right, up and down, by the fixed clamp 345 and the rotating clamp 346. The positioning is accurate, the clamping is firm and it is not easy to fall off.

Before the piston rod of the driving positioning cylinder 343 contracts upward, the spring 348 exerts a downward force on the Z-axis sliding block 342, so that during the contraction of the piston rod of the positioning cylinder 343, the rotating clamp 346 first rotates to terminal A Position left and right, and then move up to position terminal A up and down. In addition, the upper end of the Z-axis moving slide 341 is equipped with a limit screw 349 for limiting the movement of the Z-axis sliding block 342 in the positive direction of the Z-axis. The height of the limit screw 349 can be adjusted to control the upward movement of the rotating clamp 346. Control the clamping force of the rotating clamp 346 .

(1) Push the plastic shell A into the clamping part 82 through the push rod 84, and the clamping part 82 is driven by the rotating clamping cylinder 81 to clamp and fix the plastic shell B. Then, the terminal A is clamped by the pneumatic gripper 21 and rotated to the angle of docking with the plastic shell B, and then the wire on the terminal A is clamped by the pneumatic finger 33 and the terminal A is clamped by the automatic positioning terminal device 34 .

The specific steps for clamping the terminal A by the automatic positioning terminal device 34 in the above step (1) are: by driving the piston rod of the positioning cylinder 343 to shrink, the rotating clamp 346 is rotated to move closer to the fixed clamp 345, and the terminal A is positioned in the left and right direction first. . When the rotating clamp 346 can no longer rotate, the left and right positioning of the terminal A is completed. After the left and right positioning of the terminal A, the piston rod driven by the positioning cylinder 343 continues to shrink, driving the Z-axis sliding block 342 to move upward, and then driving the rotating clamp 346 moves upwards, thereby positioning and clamping the terminal A in the space formed by the first notch 3450 and the second notch 3460, that is, completing the up and down positioning of the terminal A, so far the positioning and clamping of the terminal A in four directions, left, right, up and down.

(2) After the terminal positioning and clamping device 3 clamps and fixes the terminal A, the terminal A is moved to the The position opposite to the shell B.

The wire continues to move along the positive direction of the Y-axis, so that terminal A continues to be inserted into the plastic case B, ensuring that terminal A can be inserted in place.

(4) After the terminal positioning and clamping device 3 inserts the terminal A into the plastic shell B along the positive direction of the Y-axis, during detection, the terminal positioning and clamping device 3 clamps the wire on the terminal A, and the Y-axis linear module 5 drives to move The base 71 moves along the negative direction of the Y-axis, and at this moment, the piston rod of the low-friction cylinder 722 receives a thrust along the negative direction of the Y-axis. When the thrust received by the piston rod of the low-friction cylinder 722 is greater than the force exerted by the low-friction cylinder 722 on its piston rod, and the force exerted by the low-friction cylinder 722 on its piston rod is less than that of the wire pair terminal positioning and clamping device 3 along the positive direction of the Y axis When the reaction force is low, the piston rod of the low-friction cylinder 722 shrinks, and the sliding detection device 72 and the mobile base 71 slide relative to each other, and then it is detected that the product is qualified. When the thrust received by the piston rod of the low-friction cylinder 722 and the force exerted by the low-friction cylinder 722 on its piston rod are greater than the reaction force of the wire to the terminal positioning and clamping device 3 along the positive direction of the Y axis, the piston rod of the low-friction cylinder 722 Without contraction, the sliding detection device 72 and the mobile base 71 are relatively stationary and move together, so that the terminal A is pulled out from the plastic case B, and the product is detected as unqualified.
