Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, and more specifically, the utility model relates to a cleaning device for circuit board soldering flux. Background Art

[0002] Soldering flux, also called flux, is often used in circuit board soldering work. Soldering flux is a soldering auxiliary material that can reduce the surface tension of the materials to be soldered and remove oxides. After soldering operations, there will be welding residues on the soldering flux, which will not only affect the appearance of the circuit board but also its performance. Currently, the commonly used soldering flux cleaning device is an ultrasonic cleaning machine. The traditional ultrasonic cleaning machine consists of components such as a control console, a transducer, and a cleaning tank. The cleaning tank contains a cleaning liquid and the circuit board. An ultrasonic generator is set inside the control console. The ultrasonic generator emits high-frequency signals, which are converted into mechanical energy by the transducer. A large number of bubbles are generated in the cleaning liquid by the ultrasonic waves. The bubbles explode rapidly in the cleaning liquid and effectively clean the impurities on the upper surface of the circuit board. However, during the use of the traditional ultrasonic cleaning machine, each time the circuit board needs to be put into the cleaning tank for cleaning and then fished out after cleaning, the working efficiency is low, and the user needs to contact the cleaning liquid frequently, which makes the user feel uncomfortable to a certain extent and brings inconvenience to the user. To solve the deficiencies of the existing technology, we propose a cleaning device for circuit board soldering flux. Summary of the Utility Model

[0003] To overcome the above-mentioned defects of the existing technology, the utility model provides a cleaning device for circuit board soldering flux to solve the problems that each time the circuit board needs to be put into the cleaning tank for cleaning and then fished out after cleaning during the use of the traditional ultrasonic cleaning machine, resulting in low working efficiency, and the user needs to contact the cleaning liquid frequently, which makes the user feel uncomfortable to a certain extent.

[0004] To solve the above technical problems, the utility model provides the following technical solution: A cleaning device for circuit board soldering flux, comprising a base, a control console and a cleaning tank are arranged on the top of the base, the cleaning tank is located on one side of the control console, a transducer is fixedly installed at the bottom of the cleaning tank, a circuit board workpiece and a conveying assembly are arranged on one side of the cleaning tank, the circuit board workpiece is located on one side of the conveying assembly, and a drying assembly is arranged on one side of the conveying assembly;

[0005] The conveying component includes a first bracket, which is fixedly installed on the top surface of the base. Inside the first bracket, there is a first roller conveyor and a second roller conveyor. The second roller conveyor is located below the first roller conveyor. An electric slide rail is fixedly installed at the top of the cleaning tank. One side of the electric slide rail is provided with an extension rod. The electric slide rail is used to control the up-and-down sliding of the extension rod. The bottom end of the extension rod is fixedly connected to a first mountain-shaped fork shelf. At the top of the cleaning tank, two vertical guide rods are fixedly installed on one side of the second roller conveyor. The cleaning tank is slidably connected to a transverse slide rail through the two vertical guide rods. A second bracket is fixedly installed on the top surface of the base on one side of the cleaning tank. Inside the inner wall of the second bracket, a first motor is fixedly installed. One end of the rotating shaft of the first motor is fixedly connected to a first turntable. On the outer surface edge of one side of the first turntable, a second mountain-shaped fork shelf is rotatably connected. The second mountain-shaped fork shelf is slidably connected to the inner wall of the transverse slide rail. The transverse slide rail is used to restrict the rotation of the second mountain-shaped fork shelf.

[0006] Among them, there are two of the transverse slide rail, the second bracket, the first motor, the first turntable and the second mountain-shaped fork shelf, which are respectively distributed on one side of the first roller conveyor and the second roller conveyor.

[0007] Among them, the conveying direction of the first roller conveyor is from left to right, and the conveying direction of the second roller conveyor is from right to left. One of the second mountain-shaped fork shelves is used to transport the circuit board workpiece from the first roller conveyor to the first mountain-shaped fork shelf, and the other second mountain-shaped fork shelf is used to transport the circuit board workpiece from the first mountain-shaped fork shelf to the second roller conveyor.

[0008] Among them, the drying component includes a conveyor belt, which is arranged on one side of the second roller conveyor. One side outer surface of the first bracket is fixedly installed with a second motor. One end of the rotating shaft of the second motor is fixedly connected to a rotating shaft.

Inside the first bracket, a third bracket is fixedly installed. On the bottom surface of the third bracket, a third motor is fixedly installed. One end of the rotating shaft of the third motor is fixedly connected to a fan.

[0009] Among them, six card slots are equally angularly annularly arranged on the outer wall of the second turntable. All six card slots are used to clamp the circuit board workpiece. The proximity switch, the second motor and the control console are electrically connected.

When the motor 1 is started, the turntable 1 rotates. As the turntable 1 rotates, one of the mountain-shaped fork shelves 2 transports the circuit board workpiece from the roller conveyor 1 to the mountain-shaped fork shelf 1. Subsequently, the electric slide rail controls the extension rod and the mountain-shaped fork shelf 1 to slide downwards, immersing the circuit board workpiece in the cleaning liquid in the cleaning tank for cleaning. Then, the electric slide rail controls the extension rod and the mountain-shaped fork shelf 1 to move upwards. At this time, the other mountain-shaped fork shelf 2 transports the circuit board workpiece to the roller conveyor 2. With the above structure, by rotating the turntable 1 and controlling the up and down movement of the extension rod by the electric slide rail, the transportation and cleaning of the circuit board workpiece are realized, eliminating the work of putting in and fishing out the circuit board workpiece, improving the work efficiency, avoiding the user's frequent contact with the cleaning liquid, thus preventing the user from feeling discomfort, facilitating the user to clean the welding oil on the circuit board, and enhancing the flexibility of the device;

[0013] The utility model realizes the drying of circuit board workpieces through a drying component, including a conveyor belt. After the circuit board workpiece is cleaned, a fan is used to blow dry the cleaned circuit board workpiece. When the circuit board workpiece is conveyed near the turntable 2, one of the card slots holds the circuit board workpiece. When the proximity switch detects the approach of the circuit board workpiece, the console controls the rotation of the shaft of the motor 2 by 60 degrees. After the shaft of the motor 2 rotates three times, the circuit board workpiece is turned over, and the fan blows dry the turned-over surface of the circuit board workpiece. With the above structure, by driving the circuit board workpiece to rotate by the turntable 2, the turning over of the circuit board workpiece is realized, and both sides of the circuit board workpiece can be blown dry, improving the convenience of drying the circuit board workpiece and enhancing the practicality of the device.

Under the restriction of the horizontal slide rail 68, at this time, the position of the mountain-shaped fork shelf II 613 moves along a circular trajectory with the rotation of the first turntable 612.
