Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, specifically to a substrate grinding device for processing circuit boards for toy mechanisms. Background Technology

[0002] With the rapid development of electronic technology, the toy industry is also moving towards intelligence and electronics. As the core component of intelligent toys, the performance and stability of toy mechanisms directly affect the overall quality of toys. As the foundation of mechanisms, circuit boards are crucial in terms of processing precision and quality. In the process of circuit board processing, substrate polishing is an indispensable step, which is directly related to the flatness, conductivity and subsequent assembly efficiency of the circuit board.

[0003] In the prior art, the circuit board is placed on two fixed clamps on both sides to clamp the substrate and polish the surface of the circuit board substrate. However, only clamping the two sides to polish the surface of the circuit board leaves the bottom of the board hollow. When the polishing device presses in the middle to polish, it is easy to damage the circuit board body. Since the circuit board substrate is relatively thin, it is easy to cause the board surface to bend during the operation of the polishing device. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a substrate grinding device for processing circuit boards of toy mechanisms, which aims to solve the problem that the circuit board substrate is relatively thin in the prior art, and the board surface is easily bent during the operation of the grinding device.

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

[0006] A substrate polishing device for processing circuit boards of toy mechanisms includes a worktable, a display fixedly connected to the top of the worktable, a cabinet door hinged to the front of the worktable, tempered glass fixedly connected inside the cabinet door, a three-axis motion stage fixedly connected to the top of the inner side of the worktable, a polishing roller fixedly connected to the bottom of the three-axis motion stage, a support plate fixedly connected to the bottom of the inner side of the worktable, a mounting plate and a connecting plate fixedly connected to the top of the support plate, and a receiving plate fixedly connected between the mounting plate and the connecting plate.

[0007] As a preferred embodiment of this utility model, a mounting base is fixedly connected to the top of the connecting plate, a swing rod is rotatably connected to the top of the mounting base, and a first silicone disc is fixedly connected to the top of the swing rod.

[0008] As a preferred embodiment of this utility model, an electric telescopic rod is fixedly connected to the middle of the top of the support plate, a lifting plate is fixedly connected to the top of the electric telescopic rod, a connecting ear is fixedly connected to one end of the lifting plate, and a bending rod is rotatably connected inside the connecting ear.

[0009] As a preferred embodiment of this utility model, a contact plate is fixedly connected to the bottom end of the swing rod, and a spring is fixedly connected between the swing rod and the receiving plate.

[0010] As a preferred embodiment of this utility model, a positioning post is fixedly connected to the outer wall of the mounting plate, a waist groove is opened inside the bent rod, the positioning post is slidably connected to the outside of the positioning post, and a second silicone plate is fixedly connected to the top of the bent rod.

[0011] As a preferred embodiment of this utility model, an exhaust fan is fixedly connected to the outside of the workbench, and a connecting pipe is fixedly connected to the output end of the exhaust fan, extending into the interior of the workbench.

[0012] As a preferred embodiment of this utility model, each of the four corners of the bottom of the workbench is rotatably connected to a universal wheel, and the universal wheel is a lockable universal wheel.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the contact plate is pressed by the lifting plate, at which time the swing rod tilts, and then the connecting ear rises synchronously with the lifting plate, lifting the bending rod. The bending rod is guided and pressed by the positioning pin, so that the bending rod swings inside the connecting ear. The substrate is placed on the top of the receiving plate, and the electric telescopic rod is controlled to reset. Finally, the first silicone pad is attached to the side of the substrate, and the second silicone pad is attached to the top of one side of the substrate. When the grinding roller is working, it can prevent the substrate from shifting. At the same time, the receiving plate lifts the entire substrate, effectively preventing the grinding roller from applying pressure to the substrate, which would cause the substrate to deform and bend under stress.

[0015] 2. In this utility model, by driving the exhaust fan, the connecting pipe generates suction inside the workbench, making the inside of the workbench negative pressure, thereby discharging the polished debris outside the workbench. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to 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.

[0022] Example: Please refer to Figures 1-4 This utility model provides a technical solution:

[0023] A substrate polishing device for processing circuit boards for toy mechanisms includes a worktable 1, a display 2 fixedly connected to the top of the worktable 1, a cabinet door 3 hinged to the front of the worktable 1, a tempered glass panel fixedly connected inside the cabinet door 3, a three-axis motion stage fixedly connected to the top of the inner side of the worktable 1, a polishing roller 4 fixedly connected to the bottom of the three-axis motion stage, a support plate 5 fixedly connected to the bottom of the inner side of the worktable 1, a mounting plate 6 and a connecting plate 7 fixedly connected to the top of the support plate 5, and a receiving plate 8 fixedly connected between the mounting plate 6 and the connecting plate 7. The worktable 1 is placed in a designated position, and then the circuit board substrate is placed on top of the support plate 5. The three-axis motion stage is then controlled to move, and the polishing roller 4 is controlled to rotate to polish the top of the substrate. Then the substrate is flipped over and the other side is polished. After the cabinet door 3 is closed, the polishing waste will not fly to the outside. Through the design of the tempered glass, the operator can directly observe the working situation inside the worktable 1.

[0024] Furthermore, in this embodiment, a mounting base 9 is fixedly connected to the top of the connecting plate 7, and a swing rod 10 is rotatably connected to the top of the mounting base 9. A first silicone disk 11 is fixedly connected to the top of the swing rod 10. By moving the swing rod 10, the swing rod 10 is then limited by the mounting base 9, causing the bottom end of the swing rod 10 to move axially inside the mounting base 9, making it move closer to the receiving plate 8. Then, the first silicone disk 11 is attached to one side of the substrate.

[0025] Furthermore, in this embodiment, an electric telescopic rod 12 is fixedly connected to the middle of the top of the support plate 5. A lifting plate 13 is fixedly connected to the top of the electric telescopic rod 12. A connecting ear 1301 is fixedly connected to one end of the lifting plate 13. A bending rod 15 is rotatably connected inside the connecting ear 1301. A contact plate 1001 is fixedly connected to the bottom end of the swing rod 10. A spring 14 is fixedly connected between the swing rod 10 and the receiving plate 8. A positioning post 16 is fixedly connected to the outer wall of the mounting plate 6. A waist groove 17 is opened inside the bending rod 15. The positioning post 16 is slidably connected to the outside of the positioning post 16. A second silicone plate 1501 is fixedly connected to the top of the bending rod 15. By driving the electric telescopic rod 12, the lifting plate 13 is lifted, which squeezes the contact plate 1001, so that the swing rod 10 swings inside the mounting base 9. The spring 14... During the contraction process, the swing rod 10 tilts, and then the connecting ear 1301 rises synchronously with the lifting plate 13, lifting the bending rod 15. At this time, the waist groove 17 slides outside the positioning post 16, guiding and squeezing the bending rod 15 through the positioning post 16, so that the bending rod 15 swings inside the connecting ear 1301. Finally, both the bending rod 15 and the swing rod 10 move away from the receiving plate 8, and the substrate is placed on the top of the receiving plate 8. The electric telescopic rod 12 is then reset. Finally, the first silicone pad 11 adheres to the side of the substrate, and the second silicone pad 1501 adheres to the top of one side of the substrate, thereby fixing the substrate. When the grinding roller 4 is working, it can prevent the substrate from shifting. At the same time, the receiving plate 8 lifts the entire substrate, effectively preventing the grinding roller 4 from applying pressure to the substrate, which would cause the substrate to deform and bend under stress.

[0026] Furthermore, in this embodiment, an exhaust fan 18 is fixedly connected to the outside of the workbench 1, and a connecting pipe 19 is fixedly connected to the output end of the exhaust fan 18. The connecting pipe 19 extends into the interior of the workbench 1. By driving the exhaust fan 18, the connecting pipe 19 generates suction inside the workbench 1, making the interior of the workbench 1 negative pressure, thereby discharging the polished debris outside the workbench 1.

[0027] Furthermore, in this embodiment, omnidirectional wheels 20 are rotatably connected to the four corners of the bottom of the workbench 1. The omnidirectional wheels 20 are lockable omnidirectional wheels. The design of the omnidirectional wheels 20 makes it easy to move the workbench 1 to a designated position. Finally, the omnidirectional wheels 20 are locked to complete the fixation after movement.

[0028] In this embodiment, the specific implementation scenario is as follows: The workbench 1 is placed in a designated position. The electric telescopic rod 12 is driven, which in turn lifts the lifting plate 13, squeezing the contact plate 1001. This causes the swing rod 10 to swing inside the mounting base 9, and the spring 14 contracts, causing the swing rod 10 to tilt. Then, the connecting ear 1301 rises synchronously with the lifting plate 13, lifting the bent rod 15. At this time, the waist groove 17 slides outside the positioning post 16, guiding and squeezing the bent rod 15 through the positioning post 16, causing the bent rod 15 to swing inside the connecting ear 1301. Finally, both the bent rod 15 and the swing rod 10 move away from the receiving plate 8, and the base... The substrate is placed on top of the receiving plate 8, and the electric telescopic rod 12 is reset. Finally, the first silicone pad 11 is attached to the side of the substrate, and the second silicone pad 1501 is attached to the top of one side of the substrate to fix the substrate. When the grinding roller 4 is working, it can prevent the substrate from shifting. At the same time, the receiving plate 8 supports the entire substrate, effectively preventing the grinding roller 4 from applying pressure to the substrate, which would cause the substrate to deform or bend under stress. By driving the exhaust fan 18, the connecting pipe 19 generates suction inside the worktable 1, making the inside of the worktable 1 a negative pressure state, thereby discharging the grinding debris outside the worktable 1. Through the design of the tempered glass, the operator can directly observe the working situation inside the worktable 1.

[0029] 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.
