[0001] The utility model relates to the technical field of circuit board cleaning, in particular to a cleaning device for circuit board production. Background Art

[0002] During the production process of circuit boards, it is a common phenomenon that dust adheres to the surface. After the circuit boards are manufactured, electronic components need to be mounted on the surface. The adhesion of dust will affect the mounting of electronic components and also the use of the finished products. Therefore, it is necessary to clean the circuit boards. The cleaning device in circuit board production is a device used to remove pollutants, residues, and chemicals generated during the manufacturing process. Its main function is to ensure that the circuit boards reach the necessary cleanliness and surface state after manufacturing to ensure the performance and reliability of electronic devices.

[0003] However, common circuit board cleaning equipment needs to be flipped for continuous cleaning after one side is cleaned. Due to the installation of the flipping structure, the steps and costs increase, and there is a risk of reducing the cleaning effect. In view of this, we propose a cleaning device for circuit board production. Summary of the Utility Model

[0012] Compared with the prior art, the utility model has the following beneficial technical effects:

[0013] Through the arrangement of two conveyor belt devices, the utility model facilitates the transportation of the circuit board placed between them. At the same time, driven by the motor, the two belts cooperate with the first pulleys sleeved on the two first rotating shafts to drive the two first rotating shafts to rotate simultaneously.

[0020] Embodiment

[0021] As Figures 1-4 shown, a cleaning device for circuit board production proposed by the present utility model includes a U-shaped support base 1. Two conveyor equipment 2 are symmetrically arranged and installed on both sides of the inner surface wall of the U-shaped support base 1, facilitating the transportation of the circuit board placed between the two conveyor equipment 2. Two spray plates 3 are symmetrically installed on the top and bottom wall bodies of the two conveyor equipment 2. Two water injection pipes 5 are connected to the side walls of the two spray plates 3 and are also in communication with the inside of the spray plates 3, facilitating the injection of water into their interiors. And when injecting water, under the action of the spray plates 3, the circuit board in the conveying state can be rinsed. The support frame 4 is fixedly installed on the top wall body of the U-shaped support base 1.

[0022] Furthermore, a drive assembly 6 is installed on the outer side wall of the support frame 4. The drive assembly 6 includes a first rotating shaft 61. Two first rotating shafts 61 are symmetrically arranged. An auxiliary plate is installed on the outer side wall of the support frame 4. A positioning bearing seat is installed at the bottom of the auxiliary plate. The load plate 65 is fixedly installed on the outer side wall of the support frame 4. The motor 64 is installed on the top wall body of the load plate 65 and is supported by the load plate 65. The load plate 65 and the auxiliary plate are symmetrically arranged. The top ends of the two first rotating shafts 61 are respectively connected to the output end of the motor 64 and the rotating end of the positioning bearing seat. A plurality of first pulleys 62 are evenly divided into two groups. Each group of first pulleys 62 has two. Each group of first pulleys 62 is symmetrically sleeved on the outer surface of the first rotating shaft 61 corresponding in position. Two belts 63 are sleeved in the transmission grooves of the symmetrically arranged first pulleys 62. So that when one of the first rotating shafts 61 rotates, under the transmission action of the belt 63, the other first rotating shaft 61 can be driven to rotate in cooperation with the symmetrically arranged first pulleys 62, providing power for subsequent circuit board cleaning and blowing.

[0023] Furthermore, a wiping component 7 and a blowing component 8 for facilitating the cleaning and blowing of the circuit board are symmetrically installed between the opposite wall bodies of the U-shaped support base 1 and the support frame 4. The wiping component 7 includes a second rotating shaft 71. Due to the symmetrical arrangement of the two groups of wiping components 7, the first bearing seats 72 included in each group of wiping components 7 are respectively installed on the top of the inner wall surface body of the support frame 4 and the bottom of the inner surface wall body of the U-shaped support base 1. Their rotating ends are connected to one end of the second rotating shaft 71 to assist the second rotating shaft 71 in rotating; the wiping head 73 is fixedly installed at the end of the second rotating shaft 71, and the cleaning surface is located between the two conveyor belt devices 2, facilitating the rotational wiping of the circuit board conveyed by the conveyor belt device 2. And with the arrangement of the two groups of wiping components 7, the top and bottom wall bodies of the circuit board can be wiped simultaneously, improving the cleaning efficiency; the second pulley 74 is sleeved on the outer surface of the second rotating shaft 71 to facilitate the subsequent driving of the second rotating shaft 71 to rotate.

[0024] Furthermore, the blowing component 8 includes a third rotating shaft 81. Due to the symmetrical arrangement of the two groups of blowing components 8, the second bearing seats 82 included in each group of blowing components 8 are respectively installed on the top of the inner wall surface body of the support frame 4 and the bottom of the inner surface wall body of the U-shaped support base 1, and their functions are the same as those of the first bearing seats 72 to assist the third rotating shaft 81 in rotating; the spiral fan blades 83 are sleeved on the outer surface of the third rotating shaft 81. When the third rotating shaft 81 rotates, it can drive the spiral fan blades 83 to rotate and blow-dry the top and bottom wall bodies of the circuit board in the conveying state, which is beneficial for the subsequent taking and using of the circuit board; the third pulley 84 is sleeved on the outer surface of the third rotating shaft 81 to drive the third rotating shaft 81 to rotate subsequently.

[0025] Furthermore, due to the arrangement of the two groups of wiping components 7 and the two groups of blowing components 8, and the second pulleys 74 and the third pulleys 84 included in each group of wiping components 7 and each group of blowing components 8 respectively correspond to the positions of the four first pulleys 62, the two belts 63 are also sleeved in the transmission grooves of the correspondingly positioned second pulleys 74 and third pulleys 84. Then, during the driving of the motor 64, the rotation of the two first rotating shafts 61 can be used, and in cooperation with the two belts 63 and the multiple second pulleys 74 and third pulleys 84, the purpose of simultaneously driving the two groups of wiping components 7 and the blowing component 8 to rotate can be achieved, and the cleaning work can be completed without turning the circuit board over, providing convenience for the double-sided cleaning and drying of the circuit board.
