[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model aims to solve the problems that during the spraying process, the coating thickness is uneven, affecting the appearance and performance of the product, and the excess paint will deteriorate the stability and accuracy of signal transmission of the circuit board, and provides a circuit board forming and processing device as shown in Figures 1 - 3 Figure 5, which includes a workbench 1. In the middle of the top surface of the workbench 1, a gantry 2 is fixedly connected. Between the inner walls of the gantry 2, a fixing frame 22 is arranged. Between the inner walls of the fixing frame 22, a cotton roller 21 is rotatably arranged. On one side of the fixing frame 22, a paint spraying frame 4 is arranged. On the other side of the fixing frame 22, a material receiving shell 3 is fixedly arranged. Inside the material receiving shell 3, an extrusion plate 31 is fixedly connected. The extrusion plate 31 is inclined. The extrusion plate 31 passes through the side wall of the material receiving shell 3 and is in movable contact with the outer periphery of the cotton roller 21; a structure for moving the circuit board is installed on the workbench 1, such as an electric push plate or a conveyor, etc. This kind of device is a mature technology in the prior art and is not shown in the figure. After the circuit board is placed on the workbench 1, it is moved to the lower part of the paint spraying frame 4 through the moving structure. The paint spraying frame 4 is moved. When the paint spraying frame 4 moves to a position close to the circuit board, the cotton roller 21 synchronously moves to the lower part. The paint spraying frame 4 is opened, and the paint spraying frame 4 sprays paint on the circuit board. After the painting is completed, the circuit board continues to move forward. After the circuit board contacts the cotton roller 21, the movement of the circuit board drives the cotton roller 21 to rotate. The outer periphery of the cotton roller 21 adsorbs the excess paint on the circuit board. The excess paint is removed in time, which can make the surface of the circuit board cleaner and more beautiful, avoiding appearance defects caused by uneven or overflowing paint. Removing the excess paint can ensure the stability and accuracy of signal transmission. Removing the excess paint can also facilitate the subsequent maintenance work. After the cotton roller 21 adsorbs the excess paint and continues to rotate, when it rotates to the position of the extrusion plate 31, the extrusion plate 31 extrudes the cotton roller 21, so that the paint on it falls off. The fallen paint falls into the material receiving shell 3. The material receiving shell 3 collects the excess waste materials, which is convenient for subsequent unified treatment of the waste materials, reduces the generation of waste, reduces environmental pollution, and the collected paint is reused through appropriate treatment, thus realizing the recycling of resources.

[0025] It should be noted that a pipeline for discharging waste materials is installed on the material receiving shell 3, and a manual valve with a control switch is arranged on the pipeline. When the waste materials in the material receiving shell 3 reach a certain value, the staff cleans the waste materials through the pipeline.

[0026] In the present utility model, a material storage box 42 is fixedly connected to the top of the outer wall of the gantry 2. A material conveying pump 43 is fixedly connected to the side wall of the material storage box 42. The material conveying pump 43 is communicated with a hose 44, and the end of the hose 44 is communicated with the top of the spraying rack 4. When the paint is added into the spraying rack 4 and spraying is required, the material conveying pump 43 is turned on. The material conveying pump 43 pumps out the paint from the paint bucket in the material storage box 42. The pumped-out paint flows into the spraying rack 4 through the hose 44, and the spraying rack 4 sprays out the paint, thereby realizing the spraying of the circuit board by the spraying rack 4.

[0027] It should be noted that a plurality of nozzles are installed on the spraying rack 4, and the nozzles can evenly spray the paint onto the circuit board.

[0028] In the present utility model, an electric cylinder 24 is fixedly connected to the top surface of the outer wall of the gantry 2. The end of the piston rod of the electric cylinder 24 passes through the top of the gantry 2 and is fixedly connected to the top surface of the fixing frame 22. A rotating shaft 23 is rotatably connected between the inner walls of the fixing frame 22. The outer circumference of the rotating shaft 23 is fixedly connected to the inner wall of the cotton roller 21. When the gantry 2 is opened, the gantry 2 drives the piston rod to move. The movement of the piston rod drives the fixing frame 22 to move. The fixing frame 22 drives the cotton roller 21 to move. By moving the cotton roller 21, it is convenient to be applicable to circuit boards of different thicknesses. The rotating shaft 23 connects the cotton roller 21 and the fixing frame 22, enabling the cotton roller 21 to work properly.

[0029] It should be noted that the material receiving shell 3 is a shell with an open top. The side plate of the material receiving shell 3 close to the cotton roller 21 is low, and the side plate of the material receiving shell 3 far from the cotton roller 21 is arc-shaped. The side plate of the cotton roller 21 on the higher side is arc-shaped, which can serve as a physical barrier to prevent the paint from splashing outside during the extrusion process and reduce the possibility of it directly falling on the production line or the product.

[0030] In the present utility model, a connecting rod 41 is fixedly connected to the bottom side wall of the fixing frame 22. The end of the connecting rod 41 is fixedly connected to the side wall of the spraying rack 4. The connecting rod 41 helps to connect the fixing frame 22 and the spraying rack 4. During the process of adjusting the fixing frame 22, the spraying rack 4 can also be adjusted simultaneously to achieve synchronous adjustment.

[0031] It also should be noted that the bottom surfaces of the material receiving shell 3 and the spraying rack 4 are both higher than the bottom of the cotton roller 21, preventing the material receiving shell 3 and the spraying rack 4 from contacting the circuit board and avoiding damage to the circuit board.
