Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of edge grinding devices, specifically to an edge grinding device for circuit board processing. Background Technology
[0002] A PCB edge grinding device is a specialized piece of equipment used to grind and finish the edges of PCBs. Through the high-speed rotation of components such as grinding wheels and grinding heads, it removes burrs and flash from the cut edges of the PCB, resulting in smooth, even edges that meet preset dimensional accuracy. This device is used in PCB processing because burrs, warping, or dimensional deviations are easily generated on the edges of PCBs after cutting and other processes. These defects can lead to poor contact, short circuit risks, or affect the overall structural stability of the equipment due to irregular edges. The edge grinding device effectively eliminates these problems, ensuring the electrical performance and mechanical compatibility of the PCB and meeting production accuracy requirements.
[0003] However, the existing edge grinding devices are difficult to secure effectively during use, which can cause them to loosen during edge grinding operations. This not only affects the precision and efficiency of edge grinding, but also poses a threat to the personal safety of operators and the normal operation of the equipment. Utility Model Content

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.
[0016] like Figures 1 to 6 As shown, the present invention provides a grinding device for circuit board processing, including a base plate 1, and further including: a clamping part 2, which is disposed on the top of the base plate 1; and a mounting part 3, which is disposed on the base plate 1. The clamping part 2 includes a support frame 211 fixedly connected to the top of the base plate 1. A groove 212 is provided on the support frame 211. A slider 213 is slidably connected to the inner wall of the groove 212. Two connecting rods 214 are hinged to the left side of the slider 213. A slide rail 215 is fixedly connected to the top of the support frame 211. Two sliders 216 are slidably connected to the outer surface of the slide rail 215. The ends of the two connecting rods 214 away from the slider 213 are hinged to the two sliders 216. Rubber clamps 217 are fixedly connected to the top of each slider 216. A circuit board 218 is provided on the side of the two rubber clamps 217 that are close to each other. A driving component is provided on the top of the base plate 1.

The circuit board 218 is placed between two rubber clamps 217. Then, the hydraulic push rod 219 is activated. The hydraulic push rod 219 will move the slider 213 in the slide groove 212 downward with the help of the slide groove 212. Since two connecting rods 214 are hinged on the slider 213, and the other end of the two connecting rods 214 is hinged to two sliders 216 sliding on the slide rail 215, during the movement of the slider 213, the two connecting rods 214 can drive the sliders 216 connected to the two connecting rods 214 to move the rubber clamps 217 closer to each other, and firmly clamp the circuit board 218 inside. Compared with the defects of the existing edge grinding device fixing method, this setting can effectively avoid the device from loosening during edge grinding operation by realizing synchronous clamping through connecting rod transmission. It solves the problems of low edge grinding accuracy, poor efficiency and safety hazards caused by traditional fixing methods, and greatly improves the stability of circuit board fixing.
[0017] Configuration unit 3 includes an edge grinding assembly 31, which is mounted on the top plate of the base plate 1, and a dust collection assembly 32, which is mounted on the edge grinding assembly 31 and located inside the edge grinding assembly 31. The edge grinding assembly 31 includes a slide rod assembly 311 fixedly connected to the top of the base plate 1. A top plate 312 is fixedly connected to the top of the slide rod assembly 311. A hydraulic push rod 313 is fixedly connected to the top of the top plate 312. A slide plate 314 is slidably connected to the outer wall of the slide rod assembly 311. The output end of the hydraulic push rod 313 is fixedly connected to the slide plate 314. A slide rod assembly 315 is fixedly connected to the bottom of the slide plate 314. A mounting base 316 is slidably connected to the outer wall of the slide rod assembly 315. A hydraulic push rod is provided at the bottom of the slide plate 314. Hydraulic push rod 317 has its output end fixedly connected to mounting base 316. A grinding component is mounted on mounting base 316. Hydraulic push rod 313 has its output end penetrating top plate 312 and slidably connected to it. The dust collection assembly 32 includes a support rod 321 fixedly connected to the back of mounting base 316. A dust collection hood 322 is fitted onto the support rod 321, and a connecting hose 323 is fixedly connected to the dust collection hood 322. A dust collection component is mounted on sliding plate 314. The dust collection hood 322 is adapted to the grinding component. The grinding component includes a motor 318 fixedly connected to the front of mounting base 316. The output shaft of motor 318 is fixedly connected to a rotating shaft 319 via a coupling. A grinding roller 320 is fitted onto the outer wall of rotating shaft 319. The rotating shaft 319 passes through the mounting base 316 and is rotatably connected to it. The vacuuming component includes a hoop 324 fixedly connected to the top of the slide plate 314. A vacuum cleaner 325 is fitted onto the hoop 324. The end of the connecting hose 323 extends into the vacuum cleaner 325. By setting the configuration part 3, after the circuit board 218 is fixed, the hydraulic push rod 313 can be activated. The hydraulic push rod 313, through multiple slide rods 311, allows the slide plate 314 to move the grinding component on it to contact the circuit board 218. Then, the motor 318 is started. The motor 318 drives the grinding roller 320 through the rotating shaft 319 to grind the edge of the circuit board 218. During the process, hydraulic push rod 317 can be activated. Hydraulic push rod 317, with the help of slide rod assembly 315, allows mounting base 316 to move the grinding roller 320 left and right, thereby uniformly grinding the edge of circuit board 218. This effectively ensures the precision and efficiency of the grinding process. Simultaneously, a large amount of dust is generated during grinding. At this time, vacuum cleaner 325 is activated. Vacuum cleaner 325 generates negative pressure, and through connecting hose 323, the dust suction hood 322 generates suction, drawing the dust generated during grinding into vacuum cleaner 325 via connecting hose 323. This dust removal mechanism, combined with a stable fixing method, not only solves the problems of low grinding precision, poor efficiency, and safety hazards caused by fixing defects in existing grinding devices, but also provides efficient dust removal.This minimizes the impact of dust on operators and the environment, making the entire edge grinding process more stable, precise, safe, and environmentally friendly.
[0018] In use, the circuit board 218 that needs edge grinding can be placed between two rubber clamps 217. Then, the hydraulic push rod 219 is activated. The hydraulic push rod 219 will move the slider 213 in the slide groove 212 downwards via the slide groove 212. Since two connecting rods 214 are hinged on the slider 213, and the other ends of the two connecting rods 214 are hinged to two sliders 216 sliding on the slide rail 215, during the movement of the slider 213, the sliders 216 connected by the two connecting rods 214 can be driven and hinged through the two connecting rods 214. The rubber clamps 217 on the device move closer together synchronously to firmly clamp the circuit board 218 inside. Compared with the defects of the existing edge grinding device fixing method, this setting achieves synchronous clamping through linkage transmission, which can effectively prevent the device from loosening during edge grinding operations. It solves the problems of low edge grinding accuracy, poor efficiency and safety hazards caused by traditional fixing methods, and greatly improves the stability of circuit board fixing. After the circuit board 218 is fixed, the hydraulic push rod 313 can be activated, so that the hydraulic push rod 313, with the help of multiple slide rod groups 311, can move the slide plate 314. The grinding element on the circuit board 218 is moved to contact it. Then, the motor 318 is started. The motor 318 drives the grinding roller 320 through the rotating shaft 319 to grind the edge of the circuit board 218. During the grinding process of the grinding roller 320, the hydraulic push rod 317 can also be activated. The hydraulic push rod 317, with the help of the sliding rod assembly 315, allows the mounting base 316 to drive the grinding roller 320 on it to move left and right, thereby uniformly grinding the edge of the circuit board 218, effectively ensuring the accuracy and efficiency of the grinding. At the same time, a large amount of material is generated during the grinding process. When dust is collected, the vacuum cleaner 325 is activated. The vacuum cleaner 325 generates negative pressure, which, through the connecting hose 323, causes the dust hood 322 to generate suction, drawing the dust generated during grinding into the vacuum cleaner 325 via the connecting hose 323. This dust removal mechanism, combined with a stable fixing method, not only solves the problems of low grinding accuracy, poor efficiency, and safety hazards caused by fixing defects in existing edge grinding devices, but also minimizes the impact of dust on operators and the environment through efficient dust removal, making the entire edge grinding process more stable, accurate, safe, and environmentally friendly.
