Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to a drilling flash processing device for circuit board processing. Background Art

[0002] Circuit board, also known as printed circuit board, is the provider of electrical connections for electronic components and is widely used in various electronic devices. Its Chinese name is printed circuit board. Circuit board is made by electronic printing technology, using one or more conductive layers to form the required circuit pattern on a non-conductive substrate through chemical etching or mechanical planing. In the process of circuit board processing, it is necessary to drill holes in it. When drilling, flash is inevitable, so it is necessary to use drilling flash processing equipment to deal with the flash.

[0003] As disclosed in Chinese patent: a drilling burr processing equipment, application number: CN202320099799.9, includes a workbench, wherein the upper end of the workbench is provided with two baffles of a symmetrical structure, the front end of the baffle located on the left is provided with a limit plate, and the limit plate extends to the right end of the left baffle, and the upper end surfaces of the two baffles are recessed downward to form a T-shaped slot, and the T-shaped slider is slidably connected in the T-shaped slot. The upper end of the T-shaped slider is provided with a support rod, and the upper ends of the two support rods are connected to the lower ends of the slide rod. The outer ends of the slide rod are slidably connected to the sliding sleeve, and the sliding sleeve is located between the two support rods. The fixing part of the vertically arranged lifting device is provided at the lower end of the movable part of the lifting device is provided with a grinder for grinding the burr on the circuit board, and the grinder is located between the two baffles. This design achieves the purpose of accurately processing the burr on the circuit board.

[0004] However, in the above technical solution, when fixing the circuit board, the repulsive force between the electromagnet and the magnetic block is used to squeeze and fix the circuit board. The closer the electromagnet and the magnetic block are, the greater the repulsive force is, and the farther they are, the smaller the repulsive force is. At the same time, the size of the circuit board is often not fixed and they are relatively thin. Therefore, if the circuit board is large, the electromagnet and the magnetic block will be too close, making the repulsive force too large, causing the circuit board to be squeezed and bent, causing damage to the circuit board. If the circuit board is small, the electromagnet and the magnetic block will be too far away, making the repulsive force too large or too small, and the circuit board cannot be stably fixed, making the circuit board prone to displacement and inconvenient for flashing. Utility Model Content

[0005] The main purpose of the present utility model is to provide a drilling burr treatment device for circuit board processing, which can effectively solve the problem in the background technology that when fixing the circuit board, the circuit board is squeezed and fixed by using the repulsive force between the electromagnet and the magnetic block. The closer the electromagnet and the magnetic block are, the greater the repulsive force is, and the farther they are, the smaller the repulsive force is. At the same time, the size of the circuit board is often not fixed and they are relatively thin. Therefore, if the circuit board is large, the electromagnet and the magnetic block will be too close, so that the repulsive force is too large, resulting in the circuit board being squeezed and bent, causing damage to the circuit board. If the circuit board is small, the electromagnet and the magnetic block will be too far away, so that the repulsive force is too large or too small, and the circuit board cannot be stably fixed, which makes the circuit board prone to displacement and inconvenient for burr treatment.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A drilling burr processing equipment for circuit board processing includes a base, a three-axis movable platform and a pressure plate are provided on the base, a grinder is provided on the three-axis movable platform, two constant force mechanisms are provided on one side of the pressure plate, two first push plates are provided on the constant force mechanism, a second push plate is fixedly provided on the side of the first push plate away from the pressure plate, a magnetic block and a spring are fixedly provided on the side of the second push plate away from the pressure plate, and an electromagnet is provided on the side of the magnetic block away from the pressure plate.

[0008] Preferably, one end of the spring is fixedly connected to the base, and the electromagnet is fixedly mounted on the base.

[0009] Preferably, the constant force mechanism includes a mechanism base, connecting plates are fixedly provided on both sides of the mechanism base, a first slide groove is provided on the connecting plate, a first slider is slidingly provided in the first slide groove, and a plurality of friction patterns are provided on the inner wall surface of the first slide groove.

[0010] Preferably, a rotating column is provided between the two connecting plates, a constant force spring is fixedly provided on the rotating column, a second sliding groove is provided on one side of the mechanism base, and a second slider is slidably provided in the second sliding groove.

[0011] Preferably, the mechanism base is fixedly connected to the pressure plate, the first slider is fixedly connected to the second slider, one end of the constant force spring is fixedly connected to the second slider, and the second slide groove is located between the two connecting plates.

[0012] Preferably, the first push plate is fixedly connected to the first sliding block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) When the utility model is used, the circuit board is first placed on the base, and then the repulsive force between the electromagnet and the magnetic block causes the magnetic block to move toward the circuit board. The magnetic block drives the second push plate to move, and the second push plate causes the first slider to move toward the circuit board through the first push plate. The constant deformation of the constant force spring is used to apply a constant thrust to the mechanism base, and then the mechanism base is used to push the pressure plate, so that the circuit board is fixed by the pressure plate, so that the squeezing force of the pressure plate on the circuit board is always within a constant range, thereby preventing the pressure plate from being damaged or unable to stabilize the circuit board due to changes in the size of the circuit board.

[0020] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1 and Figure 2As shown, a drilling and burring processing equipment for circuit board processing includes a base 1, a three-axis movable table 2 and a pressure plate 3 are provided on the base 1, a grinder 4 is provided on the three-axis movable table 2, two constant force mechanisms 5 are provided on one side of the pressure plate 3, two first push plates 6 are provided on the constant force mechanism 5, a second push plate 7 is fixedly provided on the side of the first push plate 6 away from the pressure plate 3, a magnetic block 8 and a spring 9 are fixedly provided on the side of the second push plate 7 away from the pressure plate 3, and an electromagnet 10 is provided on the side of the magnetic block 8 away from the pressure plate 3.

[0022] like Figure 3 and Figure 4 As shown, in another embodiment of the present invention, the constant force mechanism 5 includes a mechanism base 501, and connecting plates 502 are fixedly provided on both sides of the mechanism base 501. A first sliding groove 503 is provided on the connecting plate 502, and a first slider 504 is slidably provided in the first sliding groove 503. The inner wall surface of the first sliding groove 503 is provided with a plurality of friction patterns 505;

[0023] A rotating column 506 is provided between the two connecting plates 502, and a constant force spring 507 is fixedly provided on the rotating column 506. A second slide groove 508 is provided on one side of the mechanism base 501, and a second slider 509 is slidably provided in the second slide groove 508. When the circuit board needs to be fixed by the pressure plate 3, the first push plate 6 is first used to move the first slider 504 toward the circuit board, and then the first slider 504 drives the connecting plate 502 to move through friction, and the connecting plate 502 drives the mechanism base 501 to move, and the mechanism base 501 drives the pressure plate 3 to move. The pressure plate 3 is made to fit with the circuit board. At this time, the pressure plate 3 will stop moving, and then the first push plate 6 continues to move. The force applied by the first push plate 6 to the first slider 504 is greater than the friction force, and then the first slider 504 moves along the trajectory of the first slide groove 503. The first slider 504 drives the second slider 509 to move, and the second slider 509 extends the constant force spring 507, and the constant force spring 507 is deformed, so as to use the constant deformation of the constant force spring 507 to apply a constant thrust to the mechanism base 501, and then use the mechanism base 501 to push the pressure plate 3, so as to use the pressure plate 3 to fix the circuit board.

[0024] The working principle of this kind of drilling flash processing equipment for circuit board processing:

[0025] When in use, first place the circuit board on the base 1, then start the electromagnet 10, and the repulsive force between the electromagnet 10 and the magnetic block 8 causes the magnetic block 8 to move toward the circuit board, and the magnetic block 8 drives the second push plate 7 to move, and the second push plate 7 causes the first slider 504 to move toward the circuit board through the first push plate 6, and then the first slider 504 drives the connecting plate 502 to move through the friction force, and the connecting plate 502 drives the mechanism base 501 to move, and the mechanism base 501 drives the pressing plate 3 to move, so that the pressing plate 3 fits the circuit board, and at this time the pressing plate 3 will stop moving, and then the first push plate 6 continues to move, and the force applied by the first push plate 6 to the first slider 504 is greater than the friction force, and then The first slider 504 moves along the track of the first slide groove 503, and the first slider 504 drives the second slider 509 to move. The second slider 509 extends the constant force spring 507, and the constant force spring 507 is deformed, thereby using the constant deformation of the constant force spring 507 to apply a constant thrust to the mechanism base 501, and then using the mechanism base 501 to push the pressure plate 3, so that the pressure plate 3 is used to fix the circuit board, and then the three-axis movable table 2 and the grinder 4 are used to process the burr of the circuit board, so that the squeezing force of the pressure plate 3 on the circuit board is always within a constant range, thereby preventing the pressure plate 3 from being damaged or unable to stabilize the circuit board due to changes in the size of the circuit board.

[0026] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
