Description

Technical Field

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

[0002] In the production and processing of circuit boards, especially in the production process of double-sided circuit boards, a "copper plating and thickening" process is involved. In the process of "copper plating and thickening", a copper plate needs to be covered on the body of the circuit board, and then further processing is carried out. However, before further processing, the surface of the copper clad board needs to be removed of contaminants, otherwise it will easily affect the usability of the entire circuit board.

[0003] A Chinese patent document with publication number CN212544193U provides a copper surface contaminant removal device for circuit board processing, comprising a cleaning box, a horizontal placement plate is provided inside the cleaning box, a lifting assembly is provided on the side wall of the cleaning box, a fixing plate is fixed to the bottom of the cleaning box, vertical electric telescopic rods are fixed to both sides of the fixing plate, and a rotating screw is provided at the top of the electric telescopic rod; the rotating screw is driven to rotate by the output shaft of the first motor, thereby driving the rotating brush to move, and while the rotating brush moves, under the action of the toothed bar, the rotating brush will move and rotate, driving the bristles to rotate and clean the top surface of the circuit board, removing the contaminants remaining on the top surface of the circuit board, and cleaning the circuit board more comprehensively to achieve a better cleaning effect;

[0004] In the above scheme, during the cleaning process of the circuit board surface, the circuit board is directly placed on the surface of the placement plate without a positioning function. When the rotating brush cleans the circuit board surface, the circuit board will be offset, thereby affecting the cleaning effect of the circuit board surface; in addition, when the circuit board surface is cleaned by the rotating brush, only one side of the circuit board can be cleaned. Therefore, after cleaning one side of the circuit board, the circuit board needs to be turned over to clean the other side of the circuit board, which reduces the cleaning efficiency. Therefore, the utility model designs a copper surface contaminant removal device for circuit board processing to solve the problems existing in the prior art. Utility Model Content

After the clamping of the circuit board is completed, the output end of the first electric push rod 2 is contracted to move the support plate 3 downward. After the support plate 3 is lowered into place, the bottom of the support plate 3 is placed on the surface of the top of the cleaning box 1. At this time, by starting the ultrasonic generator 101 and the servo motor 1304, the ultrasonic generator 101 vibrates the cleaning liquid inside the cleaning box 1.

[0026] Working principle: When the power is turned on and the pollutants on the copper surface of the circuit board are cleaned, the first electric push rod 2 is started first, and the output of the first electric push rod 2 lifts the support plate 3 from the top of the cleaning box 1. After the output end of the first electric push rod 2 is extended into place, the support block 9 under the support plate 3 moves to the top of the cleaning box 1. At this time, the circuit board to be cleaned is placed between the two fixed clamping plates 407, and the second electric push rod 406 is started to pull the connecting plate 404 on one side of the top of the support plate 3 toward the direction of the gear shaft 401. At this time, the rack 405 on the surface of the connecting plate 404 is meshed with the gear shaft 401, so that the gear shaft 401 rotates, and at the same time, the gear shaft 401 is meshed with the rack 405 on the other side, so that the other connecting plate 404 is simultaneously moved closer to the gear shaft 401, and the two symmetrical fixed clamping plates 407 are driven to move closer to each other during the relative movement of the two connecting plates 404, thereby cleaning the circuit board. The two sides of the board are clamped and fixed in the grooves 4071 of the two fixed clamping plates 407 to complete the clamping and fixing of the circuit board. After the circuit board is clamped, the output end of the first electric push rod 2 is retracted to move the support plate 3 downward. After the support plate 3 is lowered into place, the bottom of the support plate 3 is placed on the surface of the top of the cleaning box 1. At this time, by starting the ultrasonic generator 101 and the servo motor 1304, the ultrasonic generator 101 vibrates the cleaning liquid inside the cleaning box 1. At the same time, the output end of the servo motor 1304 drives the first pulley 1303 at the other end of the first screw rod 6 to rotate through the transmission belt 1306. At this time, the first gear 1301 at one end of the first screw rod 6 is meshed with the second gear 1302 at one end of the second screw rod 10. At this time, the upper brush plate 8 threadedly installed on the surface of the first screw rod 6 and the lower brush plate 12 threadedly installed on the surface of the second screw rod 10 can move synchronously in the same direction to wash the upper and lower sides of the circuit board at the same time.
