Description

Technical Field

[0001] This utility model relates to the technical field of electronic product manufacturing, and in particular to a special anti-static protective device for the electronics industry. Background Technology

[0002] When electronic components are assembled and soldered after production, it usually needs to be done manually by workers. In order to avoid damage to electronic components caused by static electricity from the human body, workers usually need to wear anti-static wrist straps to ensure that the static electricity from the human body will not affect the electronic components.

[0003] Most existing electronic component assembly stations use spring ropes to fix anti-static wrist straps to the table surface. Workers must put on the anti-static wrist straps before starting work. However, existing assembly stations do not have any reminders or restrictive protective mechanisms. If workers forget to wear anti-static wrist straps and start assembly and soldering work, the impact on electronic components can be devastating, easily causing a large number of electronic components to be damaged. Therefore, there is a need for an assembly station that requires workers to wear anti-static wrist straps before it can be used. Utility Model Content

[0004] The purpose of this utility model is to provide a special anti-static work protection device for the electronics industry, in order to solve the problem mentioned in the background art that the existing electronic component assembly table does not have any reminder or restriction protection mechanism to ensure that workers wear anti-static wrist straps before performing assembly and soldering operations. This leads to the problem that if workers forget to wear anti-static wrist straps, a large number of electronic components will be damaged.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a special anti-static work protection device for the electronics industry, including a workbench, a shelf fixedly connected to the upper surface of the workbench, a first protective component fixedly connected to the left side of the workbench, a sliding groove opened on the front of the workbench, and a second protective component slidably connected to the inner wall of the sliding groove. The first protective component is used to force workers to wear anti-static equipment, and the second protective component is activated to facilitate workers to operate on the workbench. The first protective component includes an anti-static frame. A positioning groove is formed on the upper surface of the anti-static frame. A positioning block is inserted into the inner wall of the positioning groove. An anti-static wrist strap is fixedly connected to the upper surface of the positioning block. A grounding wire is fixedly connected to the surface of the anti-static wrist strap. A conductive sheet and a contact sensing sheet are fixedly connected to the inner wall of the anti-static wrist strap. An anti-static connecting rope is fixedly connected to the lower surface of the positioning block. A fixed frame is fixedly connected to the left side of the anti-static frame. A first servo motor is fixedly connected to the inner wall of the fixed frame. A connecting shaft is fixedly connected to the output end of the first servo motor. A winding roller is fixedly connected to the surface of the connecting shaft. The end of the anti-static connecting rope away from the positioning block is wound around the surface of the winding roller. A controller is fixedly connected to the front of the anti-static frame. The end of the connecting shaft away from the first servo motor is rotatably connected to the right inner wall of the anti-static frame. The controller is electrically connected to both the contact sensing sheet and the first servo motor.

[0006] Preferably, the second protective component includes a working plate, with transmission blocks fixedly connected to both the left and right sides of the working plate. The left and right inner walls of the slide groove are provided with strip grooves. The inner walls of the two strip grooves are respectively rotatably connected to and fixedly connected to a threaded rod and a locking rod. The two transmission blocks are respectively threadedly connected to and slidably connected to the surfaces of the threaded rod and the locking rod.

[0007] Preferably, a rectangular frame is fixedly connected to the back of the workbench at a position corresponding to the threaded rod. A second servo motor is fixedly connected to the inner wall of the rectangular frame. A rotating shaft is fixedly connected to the output end of the second servo motor. The front end of the rotating shaft extends into the interior of the strip groove and is fixedly connected to the rear end of the threaded rod. The second servo motor is electrically connected to the controller.

[0008] Preferably, a U-shaped frame is fixedly connected to the lower surface of both transmission blocks, and three positioning shafts are rotatably connected to the inner wall of the U-shaped frame. Friction wheels are fixedly connected to the surface of each of the three positioning shafts.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This special anti-static work protection device for the electronics industry, through the cooperative arrangement of the first and second protective components, restricts the use of the workbench by requiring workers to wear anti-static wrist straps. The anti-static wrist straps are restricted by anti-static connecting ropes, while the position of the work plate is restricted by threaded rods and transmission blocks. This ensures that workers can only pull out the anti-static wrist straps and extend the work plate when wearing them, allowing for electronic assembly operations. The workbench cannot be used without wearing the anti-static wrist straps, thus greatly improving the anti-static effect during electronic assembly operations and providing high protection for electronic components.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1-4 This utility model provides a technical solution: a special anti-static work protection device for the electronics industry, including a workbench 1, a shelf 2 fixedly connected to the upper surface of the workbench 1, a first protective component 3 fixedly connected to the left side of the workbench 1, a sliding groove opened on the front of the workbench 1, and a second protective component 4 slidably connected to the inner wall of the sliding groove. The first protective component 3 is used to force workers to wear anti-static equipment, and the second protective component 4 is activated to facilitate workers to operate on the workbench 1. The first protective component 3 includes an anti-static frame 301. A positioning groove is formed on the upper surface of the anti-static frame 301. A positioning block 302 is inserted into the inner wall of the positioning groove. An anti-static wrist strap 303 is fixedly connected to the upper surface of the positioning block 302. A grounding wire 304 is fixedly connected to the surface of the anti-static wrist strap 303. A conductive sheet 305 and a contact sensing sheet 306 are fixedly connected to the inner wall of the anti-static wrist strap 303. An anti-static connecting rope 30 is fixedly connected to the lower surface of the positioning block 302. 7. A fixed frame 308 is fixedly connected to the left side of the antistatic frame 301. A first servo motor 309 is fixedly connected to the inner wall of the fixed frame 308. A connecting shaft 310 is fixedly connected to the output end of the first servo motor 309. A winding roller 311 is fixedly connected to the surface of the connecting shaft 310. The end of the antistatic connecting rope 307 away from the positioning block 302 is wound around the surface of the winding roller 311. A controller 312 is fixedly connected to the front of the antistatic frame 301. The end of the connecting shaft 310 away from the first servo motor 309 is connected to... The right inner wall of the anti-static frame 301 is rotatably connected, and the controller 312 is electrically connected to the contact sensor 306 and the first servo motor 309 respectively. Only when the worker wears the anti-static wristband 303 on his wrist can the contact sensor 306 automatically open the first protective component 3 and the second protective component 4 through the controller 312. This can force the worker to wear anti-static equipment, thereby ensuring the safety of the entire electronic assembly process. After the worker wears the anti-static wristband 303, the first servo motor 309 is automatically turned on. At this time, the first servo motor 309 can drive the winding roller 311 to rotate through the connecting shaft 310, so that the anti-static connecting rope 307 wrapped on the surface of the winding roller 311 is loosened. The worker can take the positioning block 302 out of the slot, thereby facilitating the worker's wrist movement. The conductive sheet 305 and the grounding wire 304 can discharge human static electricity to the ground, avoiding the impact of human static electricity on electronic assembly, thereby improving the protection effect during the assembly of electronic components.

[0014] Furthermore, the second protective component 4 includes a work plate 401, with transmission blocks 402 fixedly connected to both the left and right sides of the work plate 401. The inner walls of the slide are each provided with a strip groove. A threaded rod 403 and a locking rod 404 are rotatably and fixedly connected to the inner walls of the two strip grooves, respectively. The two transmission blocks 402 are threadedly and slidably connected to the surfaces of the threaded rod 403 and the locking rod 404, respectively. A rectangular frame 405 is fixedly connected to the back of the worktable 1 at a position corresponding to the threaded rod 403. A second servo motor 406 is fixedly connected to the inner wall of the rectangular frame 405. A rotating shaft 407 is fixedly connected to the output end of the second servo motor 406, and the front end of the rotating shaft 407 extends into the strip groove. The second servo motor 406 is electrically connected to the controller 312 and fixedly connected to the rear end of the threaded rod 403. After the second servo motor 406 is started, it can drive the threaded rod 403 to rotate through the rotating shaft 407. The threaded rod 403 can drive the work plate 401 to move forward in the slide through the transmission block 402. Another transmission block 402 can slide forward on the surface of the locking rod 404, which can ensure the stability of the work plate 401 during movement. After the work plate 401 is unfolded and fills the slide, the operator can perform assembly work on the work plate 401. The work plate 401 is covered with an anti-static film, so it will not have any static electricity effect on the electronic assembly work.

[0015] Furthermore, a U-shaped frame 408 is fixedly connected to the lower surface of both transmission blocks 402. Three positioning shafts 409 are rotatably connected to the inner wall of the U-shaped frame 408. Friction wheels 410 are fixedly connected to the surface of each of the three positioning shafts 409. During the movement of the two transmission blocks 402 in the strip groove, the U-shaped frame 408 at the bottom can drive multiple sets of friction wheels 410 to rotate, thereby reducing the friction generated when the work plate 401 moves, making the work plate 401 move more smoothly and flexibly.

[0016] Working principle: When the worker is assembling electronics on the workbench 1, they first put on the anti-static wrist strap 303. At this time, the contact sensor 306 automatically activates the first servo motor 309 and the second servo motor 406 via the controller 312. The first servo motor 309 drives the winding roller 311 to rotate via the connecting shaft 310, thereby loosening the anti-static connecting rope 307. This allows the worker to pull the anti-static wrist strap 303 and the positioning block 302 out of the anti-static frame 301, facilitating wrist movement. Simultaneously, the conductive sheet 305 and the grounding wire 304 ensure that the anti-static wrist strap 303 and the positioning block 302 are properly secured. The static electricity from the human body is discharged to the ground, ensuring that the static electricity from the human body will not affect the electronic components on the workbench 1. At the same time, after the second servo motor 406 is started, it drives the threaded rod 403 to rotate through the rotating shaft 407. The threaded rod 403 can drive the work plate 401 to move forward in the slide through the left transmission block 402. During the movement, the setting of multiple sets of friction wheels 410 can reduce the friction generated during the movement of the work plate 401, making the extension of the work plate 401 smoother and more flexible. When the work plate 401 fills the slide, the worker can start the assembly work on the work plate 401.

[0017] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
