Description
Technical Field
[0001] This utility model relates to the field of thin plate suction technology, and in particular to a thin plate suction hardware assembly. Background Technology
[0002] PCB, or Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical interconnection. Because it is manufactured using electronic printing technology, it is called a "printed" circuit board. The thin plate suction assembly uses a vacuum generating device (such as a vacuum pump or vacuum generator) to extract the air between the suction cup and the thin plate contact surface, creating a vacuum negative pressure state in the sealed area. Since the external atmospheric pressure is greater than the pressure in the sealed area, the thin plate will be subjected to a force towards the suction cup under the action of the pressure difference, thus being firmly adsorbed onto the suction cup.
[0003] The existing technology has the following drawbacks: some existing thin-plate suction hardware assemblies are inconvenient to clamp and limit the PCB board during the suction process, which causes the PCB board to shift during the suction process. The shifted PCB board is prone to deviation in the cutting part during the cutting process, resulting in damage to the PCB board. This reduces the utilization rate and working efficiency of the thin-plate suction hardware assembly. Therefore, a thin-plate suction hardware assembly is proposed to solve the above problems.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Reference Figures 1-3The present invention provides an embodiment of a thin plate suction hardware assembly, including a workbench 1, a work frame 2 fixedly connected to the top of the workbench 1, a movable frame 3 slidably connected to the bottom of the work frame 2, an electric telescopic rod inside the work frame 2, the movable frame 3 being moved by the operation of the electric telescopic rod, a cutting component 4 being provided at the bottom of the movable frame 3, the cutting component 4 being used to cut the PCB board, and a placement platform 5 fixedly connected to the top of the workbench 1, the PCB board being placed on the top of the placement platform 5 to satisfy the cutting work of the PCB board;
[0037] Furthermore, a pressing rod 6 is slidably connected to the top of the placement platform 5. A limiting sliding hole is opened inside the placement platform 5, through which the pressing rod 6 slides inside the placement platform 5. Multiple limiting holes of equal size and equidistantly distributed are opened on the side wall of the pressing rod 6. A push block 7 is fixedly connected to the side wall of the pressing rod 6. The pressing rod 6 drives the push block 7 to rise and fall during the sliding process. A clamping mechanism 8 is provided on the top of the placement platform 5, and a protective component 9 is provided inside the placement platform 5.
[0038] Furthermore, the side wall of the placement platform 5 is elastically connected to the limiting rod 10 via the connecting spring 11. Pulling the limiting rod 10 stretches the connecting spring 11, causing it to deform. During reset, the rebound of the connecting spring 11 drives the limiting rod 10 to slide and reset. The limiting rod 10 passes through the placement platform 5 and is inserted into the limiting hole. By utilizing the setting of the limiting hole, the pressing rod 6 slides to a suitable position and is then inserted into the limiting hole via the limiting rod 10, thus limiting the position of the limiting rod 10. The side wall of the placement platform 5 is equipped with a vacuum pump 12. The vacuum pump 12 discharges gas molecules from the inside of the worktable 1 through specific mechanical or physical means, making the pressure inside the worktable 1 lower than atmospheric pressure to form a vacuum environment, which satisfies the adsorption and clamping effect on the PCB board.
[0039] Reference Figures 2-3 The clamping mechanism 8 includes a return spring 81. One end of the return spring 81 is fixedly connected to the top of the placement table 5, and the other end of the return spring 81 is fixedly connected to a clamping plate 83. When the clamping plate 83 is pushed, it squeezes the return spring 81, causing the return spring 81 to deform. When resetting, the spring 81 rebounds and causes the clamping plate 83 to rebound and reset. The clamping plate 83 is slidably connected to the top of the placement table 5. The side wall of the clamping plate 83 is provided with an anti-slip rubber pad. The clamping plate 83 is used to clamp and limit the PCB board placed on the worktable 1. The anti-slip effect is achieved by the anti-slip rubber pad. The side wall of the clamping plate 83 is fixedly connected to a protrusion 82. The side wall of the protrusion 82 is inclined. The side wall of the push block 7 is in contact with the side wall of the protrusion 82. The push block 7 pushes and squeezes the protrusion 82 during the sliding process. After the protrusion 82 is pushed, it causes the clamping plate 83 to slide on the top of the placement table 5.
[0040] Reference Figures 3-5 The protective component 9 includes a positioning spring 93, the bottom of which is fixedly connected to the inner bottom of the placement platform 5. A lifting plate 91 is fixedly connected to the top of the positioning spring 93. When the lifting plate 91 is pushed, it squeezes the positioning spring 93, causing the positioning spring 93 to deform. When resetting, the rebound of the positioning spring 93 causes the lifting plate 91 to slide and reset. The lifting plate 91 is slidably connected inside the placement platform 5. The bottom of the pressing rod 6 is in contact with the top of the lifting plate 91. A positioning groove is provided inside the placement platform 5. The lifting plate 91 is slidably connected in the positioning groove. The pressing rod 6 pushes the lifting plate 91 during the sliding process. A protective block 92 is fixedly connected to the top of the lifting plate 91. An adsorption hole with a size matching the protective block 92 is provided inside the placement platform 5. The adsorption hole adsorbs the bottom of the PCB board. The protective block 92 protects the adsorption hole.
[0041] Working principle: During use, the PCB board to be processed and cut is placed on the placement platform 5. Then, the limiting rod 10 is pulled and the connecting spring 11 is stretched to pull the limiting rod 10 out of the inside of the pressing rod 6. At the same time, the pressing rod 6 is pushed and the lifting plate 91 is squeezed and slid inside the placement platform 5. After the pressing rod 6 slides to the appropriate position, the push on the limiting rod 10 is released. The rebound of the connecting spring 11 causes the limiting rod 10 to pass through the placement platform 5 and insert into the inside of the pressing rod 6, thus satisfying the limitation of the pressing rod 6. At the same time, the pressing rod 6 during the descent process drives the push block 7 to descend. The push block 7 pushes the protrusion 82. After the protrusion 82 is pushed, it drives the clamping plate 83 to stretch the reset spring 81 and slide on the top of the placement platform 5. The clamping plate 83 limits the side wall of the PCB board.
[0042] After the pressing rod 6 lowers and squeezes the lifting plate 91, it squeezes the positioning spring 93 and drives the protective block 92 to slide inside the placement platform 5. After the adsorption port is exposed, the vacuum pump 12 stabilizes the PCB board on the top of the placement platform 5. Then, the cutting component 4 is used to cut the adsorbed PCB board, improving the accuracy of the PCB board cutting process.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
