Description

Technical Field

[0001] The present invention relates to the technical field of circuit board production equipment, and particularly relates to an efficient and multifunctional integrated circuit board production equipment. Background Art

[0002] During the production process of circuit boards, a large amount of colloid and residue will remain on the surface of the circuit boards. In order to prevent the colloid and residue from affecting the subsequent processing of the circuit boards, it is necessary to remove the colloid and residue from the circuit boards.

[0003] Chinese Patent with the publication number CN215301055U discloses a rapid glue residue removal device for circuit board production, including a device body, a conveyor belt, a spraying assembly, a brush, and a water spraying assembly. The surface of the device body is provided with a conveyor belt, and a spraying assembly is installed on the inner wall of the device body. Moreover, a liquid storage tank is fixed at the top of the spraying assembly. A brush rod is rotatably installed on the inner wall of the device body on one side of the spraying assembly, and a brush is sleeved on the outer wall of the brush rod. A rubber block is fixed on the inner wall of the device body below the brush, and a water spraying assembly is installed on the inner wall of the device body on one side of the brush. A water tank is installed at the top of the device body, and a water pump is installed on one side of the water tank. Although the above patent can remove the glue residue on the surface of the circuit board, when the brush continuously removes the glue residue on the surface of the circuit board, a large amount of glue residue will adhere to the brush, and the adhesion of the glue residue is likely to affect the subsequent use of the brush and the removal effect.

[0004] In response to the above problems, Chinese Invention Patent with the patent number CN118234146B discloses a glue residue removal device for circuit board production, which can remove the glue residue on the brush; during use, the circuit board is placed in the placement rack, the conveying assembly is started to rotate forward, so that the circuit board moves below the liquid spraying machine and is sprayed with sol liquid, the sol liquid melts the glue residue, and then the circuit board contacts the brush. When the brush rotates forward, the glue residue on the circuit board is brushed off, and the cleaning brush scrapes off the glue residue attached to the brush, and the scraped glue residue falls into the discharge frame through the opening to prevent the glue residue from adhering to the brush and affecting subsequent use, thereby improving the removal effect.

[0005] Although the technical solution disclosed by the glue residue removal device for circuit board production can effectively scrape off the glue residue on the brush and improve the removal effect, due to its limited structure, its applicability to circuit boards of different specifications is poor, the overall structure is complex and cumbersome, (after the brush wears) the maintenance difficulty is large and the cost is high, and the stability of the cleaning effect is also poor.
