[0001] This utility model relates to the field of electronic equipment repair technology, specifically to an integrated grounding device for an anti-static circuit board repair workbench. Background Technology
[0002] In the field of electronic equipment repair, the integration and precision of circuit boards are constantly improving. Electrostatic discharge can easily lead to component breakdown and circuit failure. Traditional grounding devices have problems such as unstable grounding resistance and low discharge efficiency.
[0003] The protection and fixation of grounding wires are key measures to ensure electrical safety and stable operation of equipment. Unprotected grounding wires are susceptible to mechanical damage and corrosion, which can lead to insulation damage, conductor breakage, leakage or grounding failure. Moreover, if not fixed, the grounding resistance will rise sharply due to vibration, dragging, etc., and static electricity cannot be discharged quickly, threatening the safety of the circuit board. Therefore, we have proposed an integrated grounding device for anti-static circuit board maintenance workbench. Utility Model Content
[0004] The purpose of this invention is to provide an integrated grounding device for an anti-static circuit board repair workbench, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated grounding device for an anti-static circuit board repair workbench, including a mixing drum and a crushing box, a feed pipe connected to the top of the mixing drum, a workbench, a rubber plate installed on the top of the workbench, and further comprising:
[0006] A protective assembly, comprising a first protective shell disposed on a workbench, a connecting rod connecting the first protective shell to the workbench, and a second protective shell disposed on the side of the workbench near the first protective shell;
[0007] A drive assembly includes a fixed shaft rotatably connected to a worktable, an elliptical disk mounted on the fixed shaft, a gear sleeved on the fixed shaft, an electric push rod mounted on the worktable, and a rack connected to the output end of the electric push rod, the rack meshing with the gear.
[0008] Furthermore, a reset assembly is provided on the first protective shell, the reset assembly including an extension plate connected to the first protective shell, a connecting plate connected to the second protective shell, and a spring connecting the connecting plate and the extension plate.
[0009] The above technical solution is adopted: by setting a reset component, when it is necessary to disconnect the connecting wire, the elliptical disk rotates in the opposite direction and separates from the second protective shell. The second protective shell can be bounced back to its original position by the elastic force of the spring.
[0010] Furthermore, a limiting component is provided on the side of the workbench near the second protective shell. The limiting component includes a limiting groove formed on the workbench, a limiting block slidably connected to the limiting groove, and the limiting block is connected to the second protective shell.
[0011] The above technical solution is adopted: by setting a limiting component, the second protective shell is limited during the movement to prevent it from deviating from the original movement trajectory.
[0012] Furthermore, a grounding component is provided on the top of the rubber plate. The grounding component includes a conductor grid, and a grounding wire is connected to the conductor grid. A grounding module is provided at the bottom of the workbench, and the end of the grounding wire away from the conductor grid is connected to the grounding module.
[0013] The above technical solution eliminates the risk of charge migration caused by potential imbalance by setting up grounding components, thus ensuring electrostatic safety during circuit board repair.
[0014] Furthermore, the top of the rubber plate has an insertion hole, and rubber pads are provided at the four corners of the bottom of the workbench.
[0015] The above technical solution is adopted: by setting up a socket for connecting the anti-static wrist strap of the maintenance personnel and the grounding wire of the equipment, the inside of the socket is directly connected to the conductor grid.
[0016] Furthermore, the inner walls of the first and second protective shells that are close to each other are connected with soft pads.
[0017] The above technical solution involves protecting the outside of the grounding wire by setting up a soft pad.
[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0019] In this invention, by setting up protective components, the cable can be prevented from loosening due to vibration or dragging, ensuring that static electricity is discharged at a microsecond speed and avoiding damage to the circuit board. At the same time, it can prevent the cable from swinging and coming into contact with live parts, reducing the risk of short circuit. It solves the problem that the protection and fixation of the grounding wire is a key measure to ensure electrical safety and stable operation of equipment. Unprotected grounding wires are susceptible to mechanical damage and corrosion, which can lead to insulation layer damage, conductor breakage, leakage or grounding failure. Moreover, if it is not fixed, the cable will loosen due to vibration or dragging, which will cause the grounding resistance to rise sharply, and static electricity cannot be discharged quickly, threatening the safety of the circuit board.

[0033] 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.
[0034] like Figures 1-5 As shown, this utility model provides a technical solution: an integrated grounding device for an anti-static circuit board repair workbench, including a workbench 1, a rubber plate 2 installed on the top of the workbench 1, and further including:
[0035] The protective component 4 includes a first protective shell 41 disposed on the workbench 1, a connecting rod 8 connecting the first protective shell 41 and the workbench 1, a second protective shell 42 disposed on the side of the workbench 1 near the first protective shell 41, and soft pads 43 connected to the inner walls of the sides of the first protective shell 41 and the second protective shell 42 that are close to each other.
[0036] The drive assembly 5 includes a fixed shaft 52 rotatably connected to the worktable 1, an elliptical disk 51 is provided on the fixed shaft 52, a gear 53 is sleeved on the fixed shaft 52, an electric push rod 55 is provided on the worktable 1, and a rack 54 is connected to the output end of the electric push rod 55, and the rack 54 meshes with the gear 53.
[0037] A grounding component 3 is provided on the top of the rubber sheet 2. The grounding component 3 includes a conductor grid 31 and a grounding wire 32 is connected to the conductor grid 31. A grounding module 33 is provided on the bottom of the workbench 1. The end of the grounding wire 32 away from the conductor grid 31 is connected to the grounding module 33.
[0038] Specifically, firstly, the electric push rod 55 is activated to drive the rack 54 to move. The rack 54 drives the gear 53 to rotate, the gear 53 drives the fixed shaft 52 to rotate, and the fixed shaft 52 drives the elliptical disk 51 to rotate. During the rotation, the elliptical disk 51 will squeeze the second protective shell 42 and push it closer to the first protective shell 41. Then, the second protective shell 42 will close with the first protective shell 41 to fix and protect the grounding wire 32. The soft pad 43 can increase the protection of the grounding wire 32.
[0039] Furthermore, such as Figure 1 As shown: The top of the rubber plate 2 is provided with a socket 9, and the four corners of the bottom of the workbench 1 are provided with rubber pads 10. The socket 9 is used to connect the anti-static wrist strap of the maintenance personnel and the grounding wire 32 of the equipment. The inside of the socket 9 is directly connected to the conductor grid 31.
[0040] The above solution also has the limitation that when the grounding wire 32 needs to be disassembled, the second protective shell 42 should automatically spring back to its original position, such as... Figure 2 As shown: A reset assembly 6 is provided on the first protective shell 41. The reset assembly 6 includes an extension plate 62 connected to the first protective shell 41. A connecting plate 61 is connected to the second protective shell 42. A spring 63 is connected between the connecting plate 61 and the extension plate 62. When the elliptical disk 51 rotates in the opposite direction and separates from the second protective shell 42, the second protective shell 42 can be bounced back to its original position by the elastic force of the spring 63.
[0041] The above solutions also require that the second protective shell 42 be limited during movement, such as... Figure 3As shown: A limit component 7 is provided on the side of the workbench 1 near the second protective shell 42. The limit component 7 includes a limit groove 71 opened on the workbench 1. A limit block 72 is slidably connected to the limit groove 71. The limit block 72 is connected to the second protective shell 42. During the movement of the second protective shell 42, the limit block 72 will be driven to slide in the limit groove 71, thereby limiting the movement trajectory of the second protective shell 42.
[0042] The working principle provided by this utility model is as follows: Figures 1-5 As shown: Before operation, the electric push rod 55 is activated, driving the rack 54 to move. The rack 54 drives the gear 53 to rotate, which in turn drives the fixed shaft 52 to rotate. The fixed shaft 52 then drives the elliptical disk 51 to rotate. During rotation, the elliptical disk 51 compresses the second protective shell 42, pushing it closer to the first protective shell 41. Simultaneously, the second protective shell 42 moves, causing the limiting block 72 to slide within the limiting groove 71, thus limiting its movement. Subsequently, the second protective shell 42 closes with the first protective shell 41. The grounding wire 32 is fixed and protected. The soft pad 43 can increase the protection of the grounding wire 32. When maintenance personnel operate the circuit board, static electricity accumulates due to human friction, equipment plugging and unplugging, or dry environment. Static charge is formed on the surface of the operating table and electronic components. It is introduced into the socket 9 through the anti-static wrist strap, then into the conductor grid 31, and then into the grounding module 33 through the grounding wire 32. When the grounding wire 32 needs to be removed, the elliptical disk 51 rotates in the opposite direction. After separating from the second protective shell 42, the second protective shell 42 can be bounced back to its original position by the elastic force of the spring 63.
[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
