Description

Technical Field

[0001] This utility model relates to the field of PCB board separation technology, and in particular to a PCB board separation device based on mechanical force separation. Background Technology

[0002] Currently, existing PCB board separation equipment (such as patent publication number: CN221081646U) discloses a PCB board separation device that sets up a left fixing mechanism and a right fixing mechanism, so that the left fixing mechanism has a left cover plate and the right fixing mechanism has a right cover plate. Furthermore, the left and right cover plates can be flipped, so the PCB board blank can be easily placed on the support plate by flipping the left and right cover plates, and the PCB board after separation can also be easily removed.

[0003] In the aforementioned patent, the two relatively moving cutting edges compress and break the PCB board during high-speed extrusion. The broken PCB board will move slightly, and under continuous cutting, it is easy to cause deviation of the cutting point, which will affect the quality of PCB board separation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a PCB board separation device based on mechanical force separation. This device solves the technical problem that when two relatively moving cutting edges compress and break the PCB board at high speed, the broken PCB board will move slightly. Under continuous cutting, this can easily lead to deviation of the cutting point, affecting the quality of PCB board separation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A PCB board separation device based on mechanical force separation, comprising a base plate, a fixed cutter and a telescopic column, wherein two electric push rods are fixedly installed at the ends of the telescopic column, and a pre-pressure plate is fixedly installed at the ends of the two electric push rods;

[0007] A dividing blade is fixedly installed at the end of the pre-pressing plate, a support frame is fixedly installed on the outer side of the pre-pressing plate, two auxiliary pressing plates are slidably installed on the inner side of the support frame, two mounting plates are fixedly installed on the outer side of each auxiliary pressing plate, and two camera lenses are fixedly installed at the end of each mounting plate.

[0008] Preferably, each of the auxiliary pressure plates has two buffer posts fixedly installed at its top end, each buffer post has a sleeve structure, and a return spring is fixedly installed inside each buffer post;

[0009] Two air jets are fixedly installed on the inner side of each mounting plate, and the end of each air jet is provided with a pipe connected to an auxiliary pressure plate.

[0010] Preferably, a wire harness is fixedly installed on the side end of each of the preload plates, and the top end of each wire harness is connected to the telescopic column;

[0011] Each auxiliary pressure plate is fixedly equipped with an air inlet pipe at its side end, and the end of each air inlet pipe is connected to a vacuum pump.

[0012] Each of the auxiliary pressure plates has a rubber pad fixedly installed at its end, and each rubber pad is made of a flexible material.

[0013] Compared with the prior art, the present invention has the following beneficial effects;

[0014] In this invention, the adhesive pad at the end of the auxiliary pressure plate is made of a flexible material. When the auxiliary pressure plate contacts the top of the PCB board before the separating blade, the adhesive pad squeezes the PCB board in a flexible manner to avoid scratching the PCB board surface with hard contact, thus achieving protective pre-fixation of the PCB board. When the auxiliary pressure plate slides upward under the reaction force of the PCB board, the buffer column is stretched, and the internal reset spring generates a reverse pulling force, so that the auxiliary pressure plate continuously applies pressure to the PCB board throughout the entire process of the separating blade moving downward, ensuring that the PCB board is stable and does not shift during separation.

[0015] In this invention, the jet nozzle on the inner side of the mounting plate is connected to the inside of the auxiliary pressure plate through a pipe, and the air inlet pipe (connected to a vacuum pump) at the side end of the auxiliary pressure plate supplies air to the inside. The airflow is sprayed from the jet nozzle to the break point of the PCB board, which can promptly blow away the debris generated during the separation process, avoid debris residue affecting subsequent processes, damage the PCB board or equipment, and keep the separation area clean.

[0022] This application provides a PCB board separation device based on mechanical force separation, which effectively solves the problem that when two relatively moving cutting edges compress and break the PCB board at high speed, the broken PCB board will move slightly, and under continuous cutting, the cutting point will easily deviate, affecting the quality of PCB board separation. The rubber pad at the end of the auxiliary pressure plate is made of flexible material. When the auxiliary pressure plate contacts the top of the PCB board before the separation blade, the rubber pad squeezes the PCB board in a flexible manner, avoiding hard contact that scratches the PCB board surface, and achieving protective pre-fixation of the PCB board. When the auxiliary pressure plate slides upward under the reaction force of the PCB board, the buffer column is stretched, and the internal reset spring generates a reverse pull force, so that the auxiliary pressure plate continuously applies extrusion force to the PCB board throughout the downward movement of the separation blade, ensuring that the PCB board position is stable and does not shift during separation.

[0023] Example

[0024] like Figures 1-4 As shown, the technical solution in this application embodiment effectively solves the technical problem that when two relatively moving cutting edges are squeezed and broken at high speed, the broken PCB board will move slightly. Under continuous cutting, this can easily lead to deviation of the cutting point, affecting the quality of PCB board separation. The overall idea is as follows:

[0025] To address the problems existing in the prior art, this utility model provides a PCB board separation device based on mechanical force separation, including a base plate 11, a fixed cutter 12, and a telescopic column 13. Two electric push rods 14 are fixedly installed at the ends of the telescopic column 13, and pre-pressing plates 15 are fixedly installed at the ends of the two electric push rods 14. At the same time, multiple rollers are installed at the top of the base plate 11 to continuously transport the PCB board. By driving the electric push rods 14, the electric push rods 14 extend and retract, generating a downward pushing force on the pre-pressing plate 15. By moving the pre-pressing plate 15, the pre-pressing plate 15 drives the separating blade 17, which moves downward, allowing the separating blade 17 to move relative to the fixed cutter 12, squeezing the break point of the PCB board, and realizing the separation operation.

[0026] A separating blade 17 is fixedly installed at the end of the pre-pressure plate 15. A support frame 18 is fixedly installed on the outer side of the pre-pressure plate 15. Two auxiliary pressure plates 19 are slidably installed on the inner side of the support frame 18. Two mounting plates 22 are fixedly installed on the outer side of each auxiliary pressure plate 19. Two camera lenses 23 are fixedly installed at the end of each mounting plate 22. By driving the pre-pressure plate 15 and the separating blade 17 to move downward synchronously, the pre-pressure plate 15, in conjunction with the fixed cutter 12, separates the PCB board. At the same time, as the pre-pressure plate 15 moves downward, it also drives the support frame 18 to move downward.

[0027] Two buffer posts 25 are fixedly installed at the top of each auxiliary pressure plate 19. Each buffer post 25 has a sleeve structure and a return spring is fixedly installed inside each buffer post 25. By moving the separating blade 17 downward, the auxiliary pressure plate 19 slides downward and contacts the top of the PCB board first. The auxiliary pressure plate 19 drives the rubber pad 21 to squeeze the top of the PCB board. The auxiliary pressure plate 19 slides upward in the opposite direction and pulls the two buffer posts 25, so that the buffer posts 25 are stretched at the top of the support frame 18. The buffer posts 25 gradually extend and retract. At the same time, the buffer posts 25 exert a pulling force on the auxiliary pressure plate 19 in the opposite direction. During the process of the separating blade 17 moving downward, the auxiliary pressure plate 19 always assists in squeezing the PCB board.

[0028] Two air nozzles 24 are fixedly installed on the inner side of each mounting plate 22. The end of the air nozzle 24 is provided with a pipe connected to the auxiliary pressure plate 19. The air nozzle 24 cleans up the debris from the PCB board separation.

[0029] Each preload plate 15 is fixedly installed with a wire harness 16 at its side end. The top of each wire harness 16 is connected to the telescopic column 13. The auxiliary pressure plate 19 is connected through the wire harness 16 to supply power to the interior of the auxiliary pressure plate 19.

[0030] Each auxiliary pressure plate 19 is fixedly installed with an air inlet pipe 26 at its side end. The end of each air inlet pipe 26 is connected to a vacuum pump. Since the mounting plate 22 has a pipe inside, and the pipe runs through the interior of the auxiliary pressure plate 19 and is connected to the air inlet pipe 26, under the gas supply of the vacuum pump, the airflow enters the interior of the auxiliary pressure plate 19 and the mounting plate 22 through the air inlet pipe 26. At the same time, the jet nozzle 24 sprays airflow to the break point of the PCB board, and cleans the debris generated during the PCB board separation by the airflow.

[0031] Each auxiliary pressure plate 19 has a plastic pad 21 fixedly installed at its end. Each plastic pad 21 is made of flexible material. The support frame 18 drives the two auxiliary pressure plates 19 to move downward. While the auxiliary pressure plates 19 slide downward, they also drive the plastic pads 21, allowing the auxiliary pressure plates 19 and the plastic pads 21 to press and fix the top of the PCB board in one step. At the same time, the pre-pressure plate 15 continues to slide downward, pressing and fixing the PCB board, and then cutting the PCB board with the separating blade 17.

[0032] Working principle:

[0033] In the first step, multiple rollers installed at the top of the base plate 11 are responsible for conveying the PCB board, so that the PCB board is continuously moved to the separation station above the fixed cutter 12, providing the workpiece to be processed for the separation operation. The two electric push rods 14 at the end of the telescopic column 13 are driven to extend and retract. The electric push rods 14 apply a downward pushing force to the pre-pressure plate 15, causing the pre-pressure plate 15 to move downward. The separation blade 17 fixed at the end of the pre-pressure plate 15 moves downward synchronously with the pre-pressure plate 15. The goal is to cooperate with the fixed cutter 12 and complete the separation by mechanically pressing the break point of the PCB board. The support frame 18 on the outside of the pre-pressure plate 15 moves downward synchronously with the pre-pressure plate 15, thereby driving the two auxiliary pressure plates 19 slidably installed on the inside of the support frame 18 to move closer to the PCB board.

[0034] Two buffer pillars 25 (in the form of a sleeve structure, with a return spring inside) are fixed at the top of the auxiliary pressure plate 19. When the support frame 18 moves the auxiliary pressure plate 19 downward, the auxiliary pressure plate 19 contacts the top of the PCB board before the separating blade 17. The rubber pad 21 (flexible material) at its end presses the top of the PCB board with the auxiliary pressure plate 19 to achieve initial fixation. If the auxiliary pressure plate 19 slides upward in the opposite direction due to the reaction force of the PCB board, it will pull the buffer pillars 25 at the top of the support frame 18 to stretch. The return spring inside the buffer pillar 25 is stretched, and at the same time, it generates a reverse pulling force on the auxiliary pressure plate 19. This ensures that the auxiliary pressure plate 19 always assists in pressing the PCB board during the entire process of the separating blade 17 moving downward, so as to ensure the stability of the PCB board position during separation.

[0035] In the second step, the end of the air intake pipe 26 is connected to the pipe inlet inside the auxiliary pressure plate 19 through a sealed connection structure. The pipe inside the auxiliary pressure plate 19 is connected to the pipe inside the mounting plate 22 through a butt-fitting sealing structure at their joint surface. The pre-pressure plate 15 continues to move downward until the separating blade 17 interacts with the fixed tool 12, mechanically pressing the break point of the PCB board, thus completing the separation of the PCB board. On the mounting plate 22 fixed to the outside of the auxiliary pressure plate 19, two camera lenses 23 monitor the separation position of the PCB board. Real-time monitoring ensures the accuracy of board separation. The two air jets 24 on the inner side of the mounting plate 22 are connected to the inside of the auxiliary pressure plate 19 through pipes. At the same time, the air inlet pipe 26 (connected to a vacuum pump at the end) at the side end of the auxiliary pressure plate 19 supplies air to the auxiliary pressure plate 19 and the mounting plate 22. The airflow is sprayed from the air jets 24 to the break point of the PCB board, which cleans up the debris generated during board separation in time. The top of the wire harness 16 at the side end of the pre-pressure plate 15 is connected to the telescopic column 13 to supply power to the electrical components such as the camera lens 23 on the auxiliary pressure plate 19, ensuring their normal operation.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
