Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing technology, specifically to a pickling device for PCB board plating processing that is easy to transport. Background Technology

[0002] Pickling is a crucial process in electronic manufacturing for removing oxides, impurities, and residual solder from the surface of PCB boards. It involves chemically cleaning the PCB board with an acidic solution to ensure the adhesion and conductivity of subsequent plating layers. The main process involves immersing the PCB board in acid for static cleaning, using manual or semi-automatic conveying methods. The system primarily includes a pickling tank, conveying fixtures, and an acid circulation pump.

[0003] Existing PCB board transportation methods cannot guarantee the continuity of the pickling process, with frequent stops during workstation changes, which greatly reduces the overall processing efficiency. Moreover, relying on manual labor or simple fixtures to transport PCB boards makes them prone to collisions during operation, resulting in scratches or peeling of the plating surface and affecting product quality. Therefore, a PCB board plating processing pickling device that is easy to transport is proposed to solve the problems mentioned above. Utility Model Content

[0004] To solve the above-mentioned technical problems, a pickling device for PCB board plating processing that is easy to transport is provided. This technical solution solves the problems of low overall processing efficiency and easy scratches or peeling of the plating surface that are mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A pickling device for PCB board plating processing that facilitates transport includes a housing. Several observation windows are provided on both the front and rear sides of the housing. A material inlet is connected to the lower end of the observation windows on the front side of the housing, and a material outlet is connected to the bottom of the rear side of the housing. A pickling chamber is provided in the cavity inside the housing. An input conveyor belt, a pickling conveyor belt, and an output conveyor belt are sequentially arranged between the two side walls of the housing along the transport direction of the PCB board. Several evenly distributed clamping mechanisms are fixedly connected to the outer surface of the pickling conveyor belt.

[0007] Preferably, the clamping mechanism includes two supports fixedly connected to the outer surface of the pickling conveyor belt. Hydraulic rods are fixedly installed on the side of each support away from the pickling conveyor belt. Connecting seats are fixedly connected to the output ends of both hydraulic rods. A connecting frame is fixedly connected to the side of each connecting seat closest to the conveyor belt. Telescopic rods are fixedly connected to the opposite sides of the two connecting seats. A forward and reverse motor is fixedly installed in the accommodating space between one end of the connecting frame and the telescopic rod. Acid-resistant clamps are fixedly connected to the side of each telescopic rod away from the connecting seats. Bidirectional threaded rods are internally threaded onto the two acid-resistant clamps.

[0008] Preferably, a limit stop is provided at the junction of the two threads of the bidirectional threaded rod.

[0009] Preferably, both ends of the bidirectional threaded rod are rotatably connected to baffles, and the shaft of the bidirectional threaded rod passes through the baffles near the forward and reverse motor and is fixedly connected to the output end of the forward and reverse motor.

[0010] Compared with the prior art, this utility model provides a pickling device for PCB board plating processing that is easy to transport, and has the following beneficial effects:

[0011] This invention, through the dynamic coordination of the clamping mechanism and the conveyor belt, can simultaneously complete clamping, releasing, and pickling operations during the continuous conveying process of PCB boards without interrupting the conveying process, effectively ensuring the continuous operation of the PCB board production line. By using the side clamping method, it can achieve stable clamping while avoiding direct contact with the PCB board surface, which not only does not affect the normal progress of the pickling process, but also prevents scratches or peeling of the plating surface due to clamping, significantly improving the overall processing efficiency and product quality.

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] Reference Figures 1-4 As shown, a PCB board plating pickling device for easy transport includes a housing 1. Several observation windows 5 are provided on both the front and rear sides of the housing 1. The lower end of the observation window 5 on the front side of the housing 1 is connected to the injection port 2, and the bottom of the rear side of the housing 1 is connected to the discharge port 4. A pickling chamber 3 is provided in the cavity inside the housing 1. Pickling liquid is introduced into the pickling chamber 3 through the injection port. After the pickling operation is completed, the waste liquid is discharged from the discharge port 4. An input conveyor belt 6, a pickling conveyor belt 8, and an output conveyor belt 7 are arranged sequentially between the two side walls of the housing 1 along the conveying direction of the PCB board. Through the control system, the conveying speeds of the input conveyor belt 6, the pickling conveyor belt 8, and the output conveyor belt 7 are made the same. First, the PCB board to be pickled is placed on the input conveyor belt 6. Several evenly distributed clamping mechanisms 9 are fixedly connected to the outer surface of the pickling conveyor belt 8.

[0020] Furthermore, the clamping mechanism 9 includes two supports 901 fixedly connected to the outer surface of the pickling conveyor belt 8. Hydraulic rods 902 are fixedly installed on the side of each support 901 away from the pickling conveyor belt 8. Connecting seats 903 are fixedly connected to the output ends of both hydraulic rods 902. A connecting frame 904 is fixedly connected to the side of the connecting seat 903 closest to the conveyor belt. Telescopic rods 905 are fixedly connected to the opposite sides of the two connecting seats 903. A clamping mechanism 905 is fixedly installed within the accommodating space between the connecting frame 904 and the telescopic rod 905. Equipped with a forward and reverse motor 910, two telescopic rods 905 are fixedly connected to acid-resistant clamps 906 on the side away from the connecting seat 903. The internal threads of the two acid-resistant clamps 906 are connected to bidirectional threaded rods 907. Limiting clips 909 are provided at the junction of the two threads of the bidirectional threaded rod 907. Both ends of the bidirectional threaded rod 907 are rotatably connected to baffles 908. The rotating shaft of the bidirectional threaded rod 907 passes through the baffles 908 near the forward and reverse motor 910 and is fixedly connected to the output end of the forward and reverse motor 910. When the PCB board on the conveyor belt 6 is conveyed between the two acid-resistant clamps 906, the forward and reverse motor 910 is activated to drive the bidirectional threaded rod to rotate. Since the two acid-resistant clamps 906 are threadedly connected to the bidirectional threaded rod 907 in both directions, they move towards the limit card 909 and cause the telescopic rod 905 to shorten until the PCB board is clamped. The clamping operation is completed synchronously during the continuous conveying of the PCB board without interrupting the conveying process. The pickling conveyor belt 8 conveys forward. When the PCB board is conveyed above the pickling chamber 3, the hydraulic rod 902 is activated to extend, immersing the PCB board clamped by the two acid-resistant clamps 906 into the pickling chamber. To ensure the service life of the equipment, the extension length of the hydraulic rod 902 must be strictly controlled. While ensuring the PCB board is completely immersed in the pickling solution, only the two acid-resistant clamping plates 906 holding the PCB board are in contact with the pickling solution to begin pickling. During pickling, the PCB board moves continuously in the pickling solution, which can wash away the solder slag on the PCB board. After pickling is completed, the hydraulic rod 902 is activated to shorten, and the PCB board leaves the pickling chamber 3. When the PCB board is conveyed above the output conveyor belt 7, the forward and reverse motor 910 is activated to reverse the direction, the two acid-resistant clamping plates 906 move away from each other, and the PCB board is placed on the conveyor belt 7 to enter the next process.

[0021] Working principle: When using this utility model, first connect the external power supply of the device, place the PCB board to be pickled on the input conveyor belt 6. When the PCB board on the conveyor belt 6 is transported between the two acid-resistant clamps 906, start the forward and reverse motor 910 to drive the bidirectional threaded rod to rotate. Since the two acid-resistant clamps 906 are threadedly connected to the threads in two directions of the bidirectional threaded rod 907, the two acid-resistant clamps 906 will move closer to the limit card 909 and drive the telescopic rod 905 to shorten until the PCB board is clamped. The pickling conveyor belt 8 conveys the PCB board forward. When the PCB board is conveyed above the pickling chamber 3, the hydraulic rod 902 is activated to extend, and the PCB board, held by two acid-resistant clamps 906, is immersed in the pickling liquid to begin pickling. During the pickling process, the PCB board moves continuously in the pickling liquid, which can wash away the solder slag on the PCB board. After pickling is completed, the hydraulic rod 902 is activated to retract, and the PCB board leaves the pickling chamber 3. When the PCB board is conveyed above the output conveyor belt 7, the forward and reverse motor 910 is activated to reverse, and the two acid-resistant clamps 906 move away from each other. The PCB board is placed on the conveyor belt 7 and enters the next process.
