Description

Technical Field

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

[0002] During manufacturing, storage, and transportation, the metal components on the surface of circuit boards (such as copper foil) easily react with oxygen in the air to form oxides. These oxides can affect the bonding strength between the metal and other materials during subsequent processing. For example, during soldering, oxides can lead to weak welds, resulting in problems such as cold solder joints or false solder joints. Acid immersion can dissolve these surface oxides through a chemical reaction, leaving the metal surface in a pure state, thereby improving soldering quality and reliability.

[0003] Chinese Utility Model Announcement No. CN221509892U includes an pickling tank, a frame fixedly installed on the pickling tank, and an electric push rod fixedly installed on the frame. The lower end of the piston rod of the electric push rod is rotatably connected to a hanging plate. The hanging plate is connected to a mounting plate via multiple tension springs. An pickling frame is fixedly connected to the bottom of the mounting plate, and a liquid level line is set on the pickling frame. A vibration motor is fixedly installed at the bottom of the hanging plate. This utility model, by setting up a hanging plate, tension springs, mounting plate, pickling frame, vibration motor, driven gear, motor, and drive gear, achieves vibration of the pickling frame during and after pickling. This assists in the contact between the circuit board and the pickling solution, promoting the removal of solder slag from the circuit board. The rotation of the hanging plate further facilitates the removal of solder slag from the circuit board, draining excess pickling solution from the circuit board, reducing the workload of the next circuit board cleaning process, thereby shortening the overall processing time and improving work efficiency.

[0004] The applicant discovered some shortcomings in the use of the patent: the circuit board is placed in the pickling frame, and because it is not fixed, the circuit board vibrates in the pickling frame, which will cause friction between the two and may cause wear on the circuit board. Moreover, the top of the pickling tank is not sealed, and the pickling liquid may splash out after vibration.

[0005] Therefore, this utility model designs an acid immersion 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 acid immersion 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 acid pickling device for circuit board electroplating, comprising: an acid pickling tank, an L-shaped bracket installed at one end of the acid pickling tank, an electric cylinder installed at the top of the L-shaped bracket, a tank cover connected to the output end of the electric cylinder, a connecting plate provided below the tank cover, a vibration assembly provided between the tank cover and the connecting plate, a plurality of L-shaped placement racks installed at the bottom of the connecting plate, an L-shaped placement groove opened on the inner wall of the L-shaped placement rack, an electric push rod fixedly installed above the L-shaped placement groove and fixed to the bottom of the connecting plate, and a U-shaped pressure plate connected to the output end of the electric push rod. When the circuit board is inserted into the L-shaped placement groove, the electric push rod is activated, causing the U-shaped pressure plate to descend and press the top of the circuit board tightly, thereby fixing the circuit board on the L-shaped placement rack. By fixing the circuit board, wear on the circuit board can be reduced during vibration pickling.

[0008] Preferably, the vibration assembly includes four vertical plates, which are respectively installed at the four bottom corners of the box cover. A groove is provided on the side of each vertical plate near the connecting plate. A limit rod is fixedly installed in the groove. A slide plate is slidably installed on the outer side wall of the limit rod. The four slide plates are respectively fixedly installed at both ends of the connecting plate. The upper and lower ends of the slide plates are connected to the vertical plates by springs. A vibrator is provided at one end of the connecting plate. When the vibrator is activated, the connecting plate vibrates. The connecting plate drives the slide plate to slide in the groove. The limit rod limits the slide plate. The slide plate slides and compresses the spring. Through the restoring force of the spring, the connecting plate can vibrate up and down.

[0009] Preferably, the surface of the spring is provided with an anti-corrosion layer, which can improve the corrosion resistance of the spring.

[0010] Preferably, both the vibrator and the electric push rod are provided with a waterproof box on their outer side, which can protect the vibrator and the electric push rod from water.

[0011] Preferably, the inner walls of the L-shaped placement groove and the U-shaped pressure plate are provided with a rubber layer, which can protect the edges of the circuit board.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model clamps and fixes the circuit board by inserting it into the L-shaped placement slot on the L-shaped placement rack and then lowering the U-shaped pressure plate through the electric push rod. The vibration component drives the connecting plate to vibrate, which reduces the wear of the circuit board. When the circuit board is pickled in the pickling box by the electric cylinder lowering the box cover, the box cover seals the top of the pickling box, which can reduce the splashing of pickling solution.
