Description

Technical Field

[0001] The utility model relates to the technical field of printed circuit boards, in particular to an automatic feeding and discharging type copper ball cleaning machine. Background Art

[0002] After copper balls are used in printed circuit board electroplating for a period of time, they often produce anode mud too quickly due to high current density, resulting in uneven coating on the board surface, incomplete etching of the board surface during the etching process, and reduced product quality. When the copper ball produces too much anode mud and the upper and lower R value deviation exceeds 10um, take out the titanium blue containing the copper ball and observe the anode mud condition of the copper ball. If the anode mud reaches the middle part of the titanium blue, the anode mud produced by the copper ball needs to be cleaned and the anode mud produced on its surface needs to be cleaned before it can continue to be used.

[0003] Therefore, it is necessary to clean the copper balls by a copper ball cleaning device. For example, Chinese patent CN210131862U discloses a copper ball cleaning machine, which relates to the field of electroplating technology and includes: a feeding device, including a feeding screen with multiple sieve holes; and a cleaning device for receiving copper balls screened by the feeding screen, including a cleaning tank, a drum, a filter tank and a fixed bracket, the drum is rotatably arranged above the cleaning tank and partially arranged in the cleaning tank; inverted teeth are arranged on the inner wall of the drum, and the inverted teeth are used to allow the copper balls to roll to the lower part of the drum when the drum rotates in the first rotation direction, and to pour out the copper balls after the copper balls are hooked to a preset height when the drum rotates in the second rotation direction; the tank body of the filter tank is located below the preset height to receive the copper balls poured out after the inverted teeth hook the copper balls to the preset height, and the tank body of the filter tank is inclined in the direction from the first end to the second end.

[0004] In the existing copper ball cleaning equipment, the cleaning efficiency of the copper balls is low, and the cleaning of the copper balls and the loading and unloading of the copper balls in the mixing barrel cannot be achieved quickly. Utility Model Content
