Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, specifically to an acidic degreasing device for circuit board electroplating. Background Technology

[0002] During the production process, circuit boards accumulate impurities such as oil, grease, dust, and oxides on their surfaces. These impurities hinder the full contact between the electroplating solution and the circuit board surface, affecting the deposition and adhesion of metal ions. Therefore, acidic degreasing agents are typically used to remove the oil from the circuit boards before electroplating.

[0003] Chinese Utility Model Announcement No. CN218710935U includes a base plate, on which a pump and a degreasing agent tank are fixedly mounted. The pump and the degreasing agent tank are connected by a pipe. An additional degreasing tank is fixedly mounted above the base plate and is connected to the degreasing agent tank. An electric slide is fixedly connected above the degreasing tank, and a clamping assembly is fixedly connected to the output end of the electric slide. A spraying assembly is located inside the degreasing tank. The spraying assembly includes a movable spraying plate with an array of nozzles, which are connected to the pump. This device can recycle the degreasing agent, improving its utilization rate and saving production costs. The device can adjust the distance between the nozzles and the circuit board to avoid damage to the circuit board due to excessive spraying speed or poor cleaning effect due to insufficient spraying speed.

[0004] The applicant discovered some shortcomings in the use of the patent: since double-sided boards require electroplating on both sides, both sides need to be degreased. The rising patent does not have the function of automatically flipping the circuit board, so the circuit board still needs to be removed from the clamps, manually flipped, and then fixed, which is not convenient. Moreover, after using acidic degreasing agent, acidic substances and emulsified or decomposed oil stains and other impurities will remain on the surface of the circuit board. The rising patent does not have a cleaning function, and these residual substances will solidify on the surface of the circuit board, which will not only corrode the circuit board, but also affect the subsequent processes.

[0005] Therefore, this utility model designs an acidic degreasing device for circuit board electroplating to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this invention is to provide an acidic degreasing device for circuit board electroplating to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an acidic degreasing device for circuit board electroplating, comprising: a base box, three gantry frames equidistantly mounted on the top of the base box, a rotating shaft rotatably mounted on the top of the middle gantry frame, the top of the rotating shaft being connected to the output end of a drive motor, a U-shaped plate mounted on the bottom of the rotating shaft, a clamping assembly provided on the U-shaped plate, lifting electric cylinders mounted on the tops of the two gantry frames on both sides, a connecting plate connected to the output end of the lifting electric cylinders, an adjusting electric push rod mounted on the side of the connecting plate near the U-shaped plate, a housing connected to the output end of the adjusting electric push rod, a plurality of nozzles provided on the side of the housing near the U-shaped plate, a pipe provided in the middle of the top of the housing, the drive motor driving the rotating shaft to rotate, thereby rotating the U-shaped plate and automatically flipping the circuit board, which is more convenient. One nozzle sprays acidic degreasing agent, and the other nozzle sprays water, which can clean the circuit board after degreasing and prevent acidic residues from corroding the circuit board.

[0008] Preferably, the clamping assembly includes four clamping electric push rods, which are respectively installed at both ends of the two sides of the U-shaped plate. The output ends of the two clamping electric push rods on both sides are fixedly installed on one side of the clamping plate. The clamping electric push rods drive the clamping plate to extend, and the two clamping plates move closer to each other to clamp the circuit board.

[0009] Preferably, both ends of the housing are equipped with adjusting electric cylinders. The output end of the adjusting electric cylinder passes through the housing and is equipped with a sealing plate. When the circuit board is narrow, the adjusting electric cylinder drives the sealing plate to extend, which prevents the nozzles at both ends of the housing from spraying degreasing agent or water, thus saving degreasing agent and water.

[0010] Preferably, two limiting rods are installed on the top inner wall of the gantry frame, and a limiting plate that engages with the limiting rods is installed on the lower outer wall of the rotating shaft. The drive motor drives the rotating shaft to rotate in both directions, and the rotating shaft drives the limiting plate to rotate. The two limiting rods can limit the limiting plate, so that the limiting plate rotates 180 degrees each time, thereby rotating the circuit board 180 degrees. This facilitates the flipping of the circuit board and prevents the circuit board from tilting after flipping, which would affect degreasing and cleaning.

[0011] Preferably, a partition plate is installed in the middle of the bottom box, and a filter screen is installed between the partition plate and the bottom box. The filter screen can filter out the degreasing agent and impurities in the water, making it convenient for recycling.

[0012] Preferably, both of the two clamps are provided with a rubber layer on the side that is close to each other, and the rubber layer can protect the surface of the circuit board.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a drive motor to rotate the shaft, which can automatically flip the circuit board without removing it, manually flipping it, and fixing it. This is more convenient and improves the degreasing efficiency. After flipping, the nozzle on one side sprays degreasing agent to degrease the other side of the circuit board, while the nozzle on the other side sprays water to clean the degreased side, which can prevent residual acidic substances from corroding the circuit board.
