DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Embodiment 1:

Referring to FIGS. 1 to 7 , 10 to 12 , and 14 to 16 , a printed circuit board mounting device includes a mounting device body 1 , both sides of the mounting device body 1 are installed with U-shaped guide strips 2 , and a conveyor belt 3 is arranged inside the U-shaped guide strip 2 , and a printed circuit board body 4 is arranged on the top of the conveyor belt 3 ;

The placement equipment body 1, U-shaped guide strip 2 and conveyor belt 3 are arranged in the same position and have the same performance as the existing similar equipment. For example, a placement robot arm is installed at the top of the placement equipment body 1, and the conveyor belt 3 is an intermittent conveying device. The conveyor belt 3 drives the printed circuit board body 4 to move and convey, and stops conveying for a period of time after the conveyor moves to the designated position inside the placement equipment body 1, so that the robot arm installed at the top of the placement equipment body 1 can complete the placement task within the time period.

A hydraulic oil storage fixed frame 5 is installed on both sides of the interior of the mounting device body 1, and a clamping seal movable frame 6 is provided inside the hydraulic oil storage fixed frame 5, and a fixed mounting block 7 is installed on the inner side wall of the clamping seal movable frame 6, and through holes 8 are evenly opened on the top of the fixed mounting block 7, and an adaptive support seal movable block 9 is provided inside the through hole 8;

The hydraulic oil storage fixed frame 5 below the clamping and sealing movable frame 6 is filled with hydraulic oil. The clamping and sealing movable frame 6 and the hydraulic oil storage fixed frame 5 are slidably connected. When the hydraulic oil is squeezed from below, the clamping and sealing movable frame 6 can move upward, so as to go up to fit with the back edge of the printed circuit board body 4, and further push the printed circuit board body 4 upward until the printed circuit board body 4 fits with the top of the inside of the U-shaped guide strip 2, so as to complete the clamping and fixing of the printed circuit board body 4, and the outer side wall of the clamping and sealing movable frame 6 is installed with a rubber sealing ring, so as to ensure the sealing between it and the hydraulic oil storage fixed frame 5;

The above-mentioned adaptive support seal movable block 9 is slidably connected with the fixed installation block 7, and a rubber sealing ring is installed on the outer side wall of the adaptive support seal movable block 9 to ensure the sealing between it and the fixed installation block 7. In the above process, the adaptive support seal movable block 9 will also be squeezed upward by the hydraulic oil inside the through hole 8 until it fits with the back of the printed circuit board body 4. When it is a double-sided printed circuit board body 4, there are some protrusions on the back of the printed circuit board body 4. At this time, each group of adaptive support seal movable blocks 9 will be restricted by the corresponding protrusions respectively, and the upward distance is different, but it can keep in contact with the corresponding protrusions, so as to play a supporting role in the subsequent mounting process;

It should be noted that, in the application process, multiple groups of adaptive support and sealing movable blocks 9 can be set according to the distribution ratio of the protrusions on the back of the existing circuit board, and the top of each group of adaptive support and sealing movable blocks 9 protrudes laterally to ensure that there is only a very small gap between adjacent adaptive support and sealing movable blocks 9, thereby ensuring that during the mounting process, all parts of the back of the printed circuit board body 4 have support parts;

An actuator for driving the hydraulic oil in the hydraulic oil storage fixing frame 5 to squeeze upward is arranged in the mounting device body 1, and the actuator includes an electric push rod 10, and the electric push rod 10 is installed at the bottom of the mounting device body 1, and a first piston plate 11 is installed at the output end of the electric push rod 10, and the first piston plate 11 is located inside the hydraulic oil storage fixing frame 5;

By controlling the electric push rod 10 to drive the first piston plate 11 to move upward, the hydraulic oil in the hydraulic oil storage fixed frame 5 can be squeezed and transported upward, thereby completing the task of driving the clamping seal movable frame 6 and the adaptive support seal movable block 9 upward;

Both ends of the bottom of the clamping seal movable frame 6 are provided with mounting grooves 12, and the interior of the fixed mounting block 7 is evenly reserved with mounting cavities 13, and both ends of the interior of the mounting cavity 13 are penetrated by mounting shafts 14, and the mounting shafts 14 extend to the interior of the mounting grooves 12, and the outer sides of the mounting shafts 14 near both ends are installed with gears 15, and the top and bottom of the outer side wall of the mounting shaft 14 are evenly installed with extrusion friction plates 27, and the extrusion friction plates 27 penetrate the fixed mounting block 7 and extend to the interior of the through hole 8;

The central axis of the installation shaft 14 is perpendicular to the transverse central axis of the fixed installation block 7, and the installation shaft 14 is rotatably connected to the clamping seal movable frame 6 and the fixed installation block 7 respectively;

In the initial state, the extrusion friction plate 27 on the mounting shaft 14 is located inside the corresponding mounting cavity 13. During use, when the mounting shaft 14 rotates clockwise, the extrusion friction plate 27 will perform a corresponding circular motion, and enter the corresponding through hole 8 through the corresponding hole, and further fit and extrude with the corresponding adaptive support and seal movable block 9. At the same time, the extrusion friction plates 27 on the adjacent mounting shafts 14 can keep one group of extrusion friction plates 27 on the mounting shafts 14 from bottom to top for the adaptive support and seal movable block 9 located in the middle position, and the extrusion friction plates 27 on the other group of mounting shafts 14 can be squeezed from top to bottom, so that the group of adaptive support and seal movable blocks 9 can be fully squeezed and fixed, thereby ensuring the supporting and stabilizing effect of the subsequent adaptive support and seal movable blocks 9;

An elastic mechanism for driving the installation shaft 14 to rotate is arranged in the installation groove 12, and the elastic mechanism includes a second piston plate 16, the second piston plate 16 is arranged in the installation groove 12, and a special-shaped rack 17 is evenly installed on the top of the second piston plate 16, and a spring 18 is connected between the special-shaped rack 17 and the clamping seal movable frame 6;

The cross-section of the special-shaped rack 17 is "L"-shaped, and the special-shaped rack 17 is meshingly connected with the gear 15;

The second piston plate 16 is sealed and slidably connected to the clamping seal movable frame 6, so that when the clamping seal movable frame 6 and the adaptive support seal movable block 9 are fully squeezed by the hydraulic oil and pressed against the printed circuit board body 4, the further upward extrusion and delivery of the hydraulic oil will start to drive the second piston plate 16 to slide upward, and the spring 18 will start to be compressed. At this time, the special-shaped rack 17 drives the corresponding installation shaft 14 to rotate, so that the extrusion friction plate 27 on the installation shaft 14 starts to perform the extrusion and stabilization task on the adaptive support seal movable block 9 as mentioned above;

It should be noted that, since the special-shaped rack 17 is "L"-shaped, when the special-shaped rack 17 drives the extrusion friction plate 27 on the mounting shaft 14 to fully squeeze the corresponding adaptive support seal movable block 9, the convex portion on the special-shaped rack 17 can fit with the top of the inside of the mounting groove 12, so that the pressure of the electric push rod 10 continues to increase significantly at this time. Based on this, it can be judged whether the clamping, fixing and supporting tasks of the printed circuit board body 4 have been completed. For example, the continued output pressure of the electric push rod 10 can be detected by a pressure detector. Once the output pressure suddenly increases, the electric push rod 10 will be stopped from continuing to work;

A printed circuit board mounting method comprises the following steps:

S1: conveying the printed circuit board body 4 to a designated position inside the mounting device body 1 through the conveyor belt 3;

S2: The circuit board is fixed, and the electric push rod 10 is controlled to drive the first piston plate 11 to move upward, and the hydraulic oil in the hydraulic oil storage fixed frame 5 is squeezed and moved upward, and the clamping and sealing movable frame 6 is further squeezed and moved upward, until the clamping and sealing movable frame 6 and the adaptive supporting and sealing movable block 9 are fully fitted with the bottom of the printed circuit board body 4, and the printed circuit board body 4 is further pushed upward until the printed circuit board body 4 is fit and squeezed with the top inside the U-shaped guide strip 2, thereby completing the fixing and support of the printed circuit board body 4;

S3: Accessory placement, where the placement robot installed on the top of the placement equipment body 1 picks up the accessory and further places it on a designated position on the printed circuit board body 4;

S4: Release the fixation. After the mounting is completed, the electric push rod 10 is controlled to drive the first piston plate 11 to move downward to release the clamping fixation of the printed circuit board body 4, and the mounted printed circuit board body 4 is conveyed to the subsequent processing equipment through the conveyor belt 3.

Example 2

Please refer to FIG. 2 , FIG. 8 , FIG. 9 and FIG. 13 , both sides of the top of the hydraulic oil storage fixed frame 5 are provided with mounting holes 19 , and mounting kits 20 are provided inside the mounting holes 19 , and both sides of the top of the clamping and sealing movable frame 6 are provided with T-shaped slots 21 ;

The T-slot 21 is provided with an extrusion mechanism for positioning the printed circuit board body 4, and the extrusion mechanism includes a T-shaped movable block 22, which is provided inside the T-slot 21, and an extrusion positioning plate 23 is installed on the top of the T-shaped movable block 22, and a connecting movable plate 24 is installed on the bottom of the extrusion positioning plate 23, and the connecting movable plate 24 extends to the inside of the installation kit 20;

The extrusion positioning plate 23 is triangular, and the extrusion positioning plate 23 and the connecting movable plate 24 are made in one piece;

The installation kit 20 is slidably connected to the connecting movable plate 24, so that when the clamping and sealing movable frame 6 moves upward to squeeze and push the printed circuit board body 4, the squeezing and positioning plate 23 can move upward synchronously. When the printed circuit board body 4 has a small lateral deviation, the printed circuit board body 4 will be squeezed with the beveled portion of the top of the squeezing and positioning plate 23, so that the printed circuit board body 4 can move horizontally accordingly until the printed circuit board body 4 is located between the two sets of squeezing and positioning plates 23, thereby further correcting the position of the printed circuit board body 4.

A driving mechanism for driving the installation kit 20 to move is arranged in the installation hole 19, and the driving mechanism includes a servo motor 25, which is installed on one side of a group of installation holes 19, and the output end of the servo motor 25 is connected to a positive and negative screw rod 26, and the positive and negative screw rod 26 respectively penetrates the hydraulic oil storage fixing frame 5 and the installation kit 20;

The forward and reverse screw rods 26 are rotationally connected to the hydraulic oil storage fixing frame 5, and the forward and reverse screw rods 26 are threadedly connected to the installation kit 20;

The forward and reverse screw rods 26 are sealed and rotatably connected to the hydraulic oil storage fixed frame 5 through sealed bearings, and the T-shaped movable block 22 and the corresponding T-shaped slot 21 form a relative sliding structure, so that when the staff controls the servo motor 25 to drive the forward and reverse screw rods 26 to rotate, the two sets of installation kits 20 can move in opposite directions, thereby driving the two sets of extrusion positioning plates 23 to move in opposite directions, and then can be adjusted according to the specific length of the printed circuit board body 4, so as to facilitate the positioning and deviation correction tasks for the printed circuit board bodies 4 of different lengths;

It should be noted that the position of the forward and reverse screw rods 26 is between the highest stroke of the first piston plate 11 and the lowest stroke of the clamping and sealing movable frame 6 to avoid interference with the first piston plate 11 and the clamping and sealing movable frame 6.

The working principle of the present invention is as follows: the conveyor belt 3 drives the printed circuit board body 4 to move to the designated position inside the mounting equipment body 1 and then stops, and the electric push rod 10 is controlled to drive the first piston plate 11 to move upward, and the hydraulic oil in the hydraulic oil storage fixed frame 5 is squeezed and transported upward, thereby driving the clamping and sealing movable frame 6 and the extrusion positioning plate 23 upward, and the clamping and sealing movable frame 6 pushes the printed circuit board body 4 upward until the printed circuit board body 4 is pressed against the top of the U-shaped guide strip 2, thereby clamping and fixing the printed circuit board body 4;

In the above process, when the position of the printed circuit board body 4 deviates from the expected position, the printed circuit board body 4 can be squeezed with the beveled portion at the top of the printed circuit board body 4, so that the printed circuit board body 4 moves laterally until the printed circuit board body 4 is located between the two groups of extrusion positioning plates 23, and the position between the two groups of extrusion positioning plates 23 is exactly the same as the expected position, so the deviation correction and positioning task of the printed circuit board body 4 can be completed, and at the same time, the adaptive support and sealing movable block 9 can move upward under the extrusion of hydraulic oil and fit and extrude with the back of the printed circuit board body 4. When the printed circuit board body 4 is a double-sided model with a protruding portion on the back, the upward distance of each group of adaptive support and sealing movable blocks 9 is different, but they all maintain fit and extrusion with the back of the printed circuit board body 4 in the end;

When the clamping seal movable frame 6 and the adaptive support seal movable block 9 complete the fitting and extrusion of the printed circuit board body 4, since the elastic force of the spring 18 is significantly greater than the gravity of the clamping seal movable frame 6 and the adaptive support seal movable block 9, the hydraulic oil begins to enter the interior of the mounting groove 12 under the extrusion of the first piston plate 11 to squeeze the second piston plate 16, so that the special-shaped rack 17 moves upward, the spring 18 is compressed, and the multiple groups of mounting shafts 14 begin to rotate clockwise, and drive the extrusion friction plates 27 to squeeze the corresponding adaptive support seal movable blocks 9, and the extrusion friction plates 27 on the adjacent mounting shafts 14 cooperate with each other to squeeze the adaptive support seal movable block 9 located in the middle from the opposite direction, thereby ensuring the subsequent support effect of the adaptive support seal movable block 9;

When the extrusion friction plate 27 has fully extruded the adaptive support seal movable block 9, the raised portion on the special-shaped rack 17 fits with the top of the inside of the mounting groove 12. At this time, the pressure of the electric push rod 10 to continue to move upward is significantly increased, so the electric push rod 10 stops working, and the placement task is implemented by the placement robot arm installed at the top of the inside of the placement equipment body 1;

After the mounting task is completed, the electric push rod 10 is controlled to drive the first piston plate 11 downward to the initial position, and the spring 18 drives the special-shaped rack 17 to move downward first, and the extrusion friction plate 27 releases the extrusion of the corresponding adaptive support sealing movable block 9, and then the clamping sealing movable frame 6, the adaptive support sealing movable block 9 and the extrusion positioning plate 23 are moved downward, and the printed circuit board body 4 is re-attached to the conveyor belt 3. At this time, the conveyor belt 3 just starts to restart and transports the printed circuit board body 4 to subsequent processing or collection equipment.

The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
