Detailed Implementation
[0022] 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.
[0023] Reference Figures 1-3 This utility model provides an embodiment of a circuit board processing corner cutting device, including a base plate 1, a protective box 2 fixedly connected to the bottom end of the base plate 1, a motor 3 installed on the front outer wall of the protective box 2, a worm gear 4 fixedly connected to the drive end of the motor 3, a worm wheel 5 meshing with the outer wall of the worm gear 4, a rotating shaft 6 fixedly connected to the inner wall of the worm wheel 5, a placement plate 7 fixedly connected to the top end of the rotating shaft 6 through the inner wall of the protective box 2, sliding grooves opened at the left and right ends of the placement plate 7, a fixing component provided on the inner wall of the placement plate 7, the fixing component including a lead screw 8 rotatably connected to the inner wall of the placement plate 7, a sliding plate 9 threadedly connected to the front and rear ends of the lead screw 8, a clamping plate 10 fixedly connected to the top left and right ends of the sliding plate 9, a throttle 11 installed at the front end of the lead screw 8, and the sliding plate 9 slidably connected to the inner wall of the sliding groove.
[0024] Specifically, a protective box 2 is fixedly connected to the bottom of the base plate 1. The protective box 2 is built under the base plate 1 by this fixed connection method, which plays a role in protecting the internal components. When the placement plate 7 needs to be adjusted in angle, the motor 3 is started. The motor 3 is installed on the front outer wall of the protective box 2 and is fixed to the protective box 2 by this installation method. The motor 3 provides the power source for subsequent transmission. The drive end of the motor 3 is fixedly connected to the worm gear 4, which means that when the motor 3 is running, it can directly drive the worm gear 4 to rotate. The outer wall of the worm gear 4 is meshed with the worm wheel 5. By using the rotation of the worm gear 4, the worm wheel 5 is driven to rotate through the meshing transmission. The inner wall of the worm wheel 5 is fixedly connected to the rotating shaft 6. So when the worm wheel 5 rotates, it can drive the rotating shaft 6 to rotate synchronously. The top of the rotating shaft 6 passes through the inner wall of the protective box 2 and is fixedly connected to the placement plate 7. In this way, the rotation of the rotating shaft 6 can drive the placement plate 7 to perform the corresponding rotation action, which is convenient for adjusting the angle of the placement plate 7.
[0025] The lead screw 8 is located on the inner wall of the placement plate 7 and is rotatably connected to it, allowing the lead screw 8 to rotate flexibly within the placement plate 7. The front and rear ends of the lead screw 8 are threadedly connected to the slide plate 9. When the lead screw 8 rotates, it drives the slide plate 9 to move along the axis of the lead screw 8 by relying on the thread transmission principle. The top left and right ends of the slide plate 9 are fixedly connected to the clamping plates 10. The movement of the slide plate 9 will drive the clamping plates 10 to move synchronously, thereby realizing the clamping or loosening operation of circuit boards and other objects. The front end of the lead screw 8 is equipped with a throttle 11. The operator provides external force for the rotation of the lead screw 8 by rotating the throttle 11, thereby controlling the operation of the entire fixing component. The slide plate 9 is slidably connected to the inner wall of the slide grooves opened at the left and right ends of the placement plate 7. The slide grooves guide and limit the movement of the slide plate 9, ensuring that the slide plate 9 can move smoothly along the predetermined direction, realizing convenient and stable circuit board fixing operation.
[0026] Reference Figure 4 A fixing plate 12 is fixedly connected to the rear top of the base plate 1. An electric push rod 13 is installed on the front top of the fixing plate 12. A dust box 14 is fixedly connected to the drive end of the electric push rod 13. A dust collection assembly is provided at the top of the dust box 14. The dust collection assembly includes a collection box 15 fixedly connected to the top of the dust box 14. A fan 16 is installed on the front outer wall of the collection box 15. A duct 17 is fixedly connected to the front outer wall of the fan 16. A suction port 18 is fixedly connected to the bottom end of the duct 17. A connecting plate 19 is fixedly connected to the inner wall of the dust box 14. A second motor 20 is installed at the top of the connecting plate 19. A chamfering disc 21 is fixedly connected to the drive end of the second motor 20.
[0027] Specifically, a fixing plate 12 is fixedly connected to the rear top of the base plate 1, thereby securely mounting the fixing plate 1 on the base plate 1 and providing a support base for subsequent components. An electric push rod 13 is mounted on the front top of the fixing plate 12. The electric push rod 13 is fixed to the fixing plate 12 in this way and can extend and retract with the support of the fixing plate 12. A dust box 14 is fixedly connected to the drive end of the electric push rod 13. When the electric push rod 13 extends or retracts, it can drive the dust box 14 to move in the front-back direction. The collection box 1 in the dust collection assembly... 5 is fixedly connected to the top of the dust box 14. The collection box 15 is integrated with the dust box 14 by means of this connection. A fan 16 is installed on the front outer wall of the collection box 15. The fan 16 is connected to the collection box 15 by the installation method to provide power for dust collection. A duct 17 is fixedly connected to the front outer wall of the fan 16. The suction force generated by the fan 16 when it is working can be transmitted through the duct 17. A suction port 18 is fixedly connected to the bottom end of the duct 17, so that the suction port 18 can generate suction force under the action of the fan 16 to realize the dust collection function.
[0028] A connecting plate 19 is fixedly connected to the inner wall of the dust box 14. The connecting plate 19 is fixed inside the dust box 14 to provide an installation position for the second motor 20. The second motor 20 is installed on the top of the connecting plate 19. The second motor 20 is fixed to the connecting plate 19 by installation. A chopping disc 21 is fixedly connected to the drive end of the second motor 20. When the second motor 20 is running, it can drive the chopping disc 21 to rotate, thereby realizing the chopping operation of the circuit board.
[0029] Working Principle: When it is necessary to cut the corners of the circuit board, the operator first turns the handle 11, causing the lead screw 8 to rotate within the placement plate 7. The threaded transmission causes the slide plate 9 to move axially along the lead screw 8, which in turn moves the clamping plate 10 to fix the circuit board onto the placement plate 7. If the cutting angle of the circuit board needs to be adjusted, motor 3 is started. Motor 3 drives the worm gear 4 to rotate, and the worm gear 4, through meshing transmission, causes the worm wheel 5 to rotate, which in turn drives the rotating shaft 6 and the placement plate 7 to rotate, thus achieving angle adjustment. Then, the electric push rod 13 is started, pushing the dust box 14 forward to the appropriate position. Simultaneously, motor 20 is started, driving the cutting disc 21 to rotate and cut the corners of the circuit board. During the cutting process, the fan 16 is started, and the suction force generated is transmitted through the air duct 17 to the dust inlet 18, sucking the dust and other debris generated during cutting into the collection box 15, thus achieving a dust removal function. This allows for convenient and precise circuit board cutting and effective dust removal.
