Technical Field
[0001] The utility model relates to the technical field of PCBA board production, and particularly relates to a PCBA board splitting machine with a dust removal device. Background Art
[0002] PCBA (Printed Circuit Board Assembly) board is an abbreviation for printed circuit board assembly, which is a process of soldering electronic components (such as electronic elements, chips, resistors, etc.) onto a printed circuit board. PCBA boards are usually used in the manufacture of various electronic products, such as computers, mobile phones, televisions, etc. A PCBA board splitting machine is a device used to separate a PCBA board into independent single circuit boards. In electronic manufacturing, multiple small circuit boards are usually assembled on a larger printed circuit board at the same time, and the PCBA board splitting machine can cut them into separate circuit boards for subsequent testing, packaging, and assembly. A PCBA board splitting machine with a dust removal device is a PCBA board splitting machine added with a dust removal device. During the operation of such a device, in addition to completing the function of splitting the board, it can effectively collect and process the dust and waste generated during the board splitting process. The design of this dust removal device aims to improve the cleanliness of the production environment and prevent the impact of dust on the equipment and the working environment.
[0003] In some existing PCBA board splitting machines with dust removal devices, after the fan used for dust suction has been used for a long time, a large amount of dust will also accumulate on the surface of the dust-proof cloth that helps the fan isolate the vast majority of dust. Excessive dust will block the ventilation holes on the surface of the dust-proof cloth, resulting in a decrease in the air permeability of the dust-proof cloth, thereby weakening the dust suction effect of the fan, making the dust removal device unable to effectively clean the dust generated during the board splitting, and reducing the dust removal efficiency.

[0028] Working principle: The PCBA board that has not been divided is transported from the top of conveyor belt 2. Motor 1 will drive the board divider 4 to rotate and divide the PCBA board that has not been divided. The dust generated during the dividing process will be carried by the blower 9 through the suction pipe 7 into the sedimentation cylinder 6 for sedimentation. However, after the blower 9 has been used for a long time, too much dust will accumulate on the surface of the dust-proof cloth 19 responsible for dust separation, affecting the dust suction efficiency of the blower 9. At this time, start motor 2, drive the threaded rod 11 to rotate through motor 2, and then drive the sliding block 13 to slide up and down inside the sliding groove 12. While the sliding block 13 is sliding, the first push spring 17 inside it will push the cleaning block 18 to make the cleaning block 18 closely fit the surface of the dust-proof cloth 19, and scrape and clean the surface of the dust-proof cloth 19 with high efficiency. By using the cleaning device to clean the surface of the dust-proof cloth 19, it is avoided that the ventilation holes of the dust-proof cloth 19 are blocked by dust, increasing the working efficiency of the blower 9 and improving the dust removal effect of the dust removal device. The PCBA board after being divided will be sent into the inside of the collection box 26 under the transportation of conveyor belt 2, and the collection box 26 will be unloaded. However, when unloading, the PCBA board may shift due to conveyor belt 2 and cannot accurately fall into the inside of the collection box 26. But the two baffles 21 will be pushed by the second push spring 22 to prevent the PCBA board from shifting, making the falling distribution of the PCBA board more concentrated and enabling it to accurately fall into the inside of the collection box 26. And by adjusting the position of the limit block 24 threadedly connected to the limit rod 23, the opening angle of the two baffles 21 can also be adjusted to further adjust the falling distribution of the PCBA board, improving the flexibility and applicability of use.
