Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to a circuit board coating device. Background Technology

[0002] Lamination, also known as "coating," "mounting," or "film application," refers to the process of applying a transparent plastic film to the surface of printed materials through heat and pressure, serving to protect the material and enhance its gloss. Lamination has a wide range of applications. During PCB circuit board production, lamination is often performed on the surface because the circuit board surface is easily damaged. Laminating the surface protects the circuit board from scratches.

[0003] According to the patent application published on the Internet (authorization announcement number: CN 217622190 U), "This utility model relates to the field of laminating machine technology, specifically a laminating device for PCB circuit boards, including an automatic laminating machine body. A conveyor belt is provided on the top plate of the automatic laminating machine body. A mounting frame is fixedly installed at one end of the top plate of the automatic laminating machine body. A first cylinder is fixedly installed on the bottom surface of the top plate of the mounting frame. A first drive motor is fixedly connected to the piston rod of the first cylinder. A cleaning block is fixedly connected to the rotating rod of the first drive motor. A processing chamber is opened on one side of the automatic laminating machine body. A vacuum cleaner is fixedly installed inside the processing chamber. By setting up the first cylinder, cleaning block, processing chamber and vacuum cleaner for coordinated use, the surface of the circuit board can be cleaned before laminating, thereby ensuring the cleanliness of the circuit board surface and avoiding the situation where dust and other impurities affect the laminating effect of the circuit board."

[0004] Regarding the above description, the applicant believes the following problems exist: When the device is in use, as the circuit board is transported to the bottom of the conveyor belt, the first cylinder drives the small motor to descend, and at the same time, the first drive motor drives the cleaning block to rotate. The cleaning block cleans the surface of the circuit board, and the vacuum cleaner pumps the dust generated during cleaning into the collection box. By setting up the first cylinder, cleaning block, processing chamber and vacuum cleaner to work together, the surface of the circuit board is cleaned before the coating operation. However, the device lacks a positioning mechanism during the cleaning and coating process, which may cause the circuit board to shift during cleaning and lead to inaccurate coating due to misalignment of the circuit board during coating. Utility Model Content

[0005] To overcome the problem that the device cannot position the circuit board.

[0006] The technical solution of this utility model is as follows: a circuit board coating device, including a support plate; it also includes a fixing component and a coating assembly. The coating assembly is provided on the outside of the support plate. The fixing components are fixedly connected to both sides of the bottom of the support plate. The outer shell is fixedly connected to the middle of the bottom of the support plate. A motor is fixedly connected inside the outer shell. A rotating component is fixedly connected to the output end of the motor. A shaped component is rotatably connected inside the rotating component. A sliding component is rotatably connected to the top of the shaped component. A push plate is fixedly connected to the middle of the top of the sliding component. A transmission rod is fixedly connected to both sides of the top of the sliding component. A positioning rod is rotatably connected to the top of the transmission rod. A rotating wheel is rotatably connected to the bottom of the positioning rod.

[0007] Preferably, a groove is provided at the corresponding position of the fixing member and the sliding member, and the sliding member is slidably connected to the outside of the fixing member.

[0008] Preferably, the support plate has holes at the corresponding positions of the positioning rod, and the positioning rod is rotatably connected inside the support plate.

[0009] Preferably, a groove is provided at the corresponding position of the support plate and the slider, and the slider is slidably connected inside the support plate.

[0010] Preferably, the contact surface between the push plate and the circuit board is made of rubber with anti-slip patterns.

[0011] Preferably, the coating assembly includes a support leg, which is disposed outside the support plate. A second motor is fixedly connected inside the support leg. A roller is fixedly connected to the output end of the second motor. A conveyor belt is driven to the outside of the roller. A support member is disposed outside the conveyor belt. A coating device is fixedly connected inside the support member.

[0012] Preferably, the support member and the support plate are provided with grooves at corresponding positions, and the support plate is fixedly connected inside the support member.

[0013] The beneficial effects of this utility model are as follows: By starting motor two, the rollers are driven to rotate, so that the conveyor belt transports the circuit board. When the circuit board is delivered to the corresponding position of the support, the transport stops. Starting motor one drives the rotating component to rotate, so that the irregular component pulls the sliding component closer to each other. Thus, while moving, the transmission rod is pulled to drive the positioning rod to rotate. Then, the circuit board is pushed by the push plate and the rotating wheel positions the circuit board. After the circuit board is positioned, the coating device is started to coat the circuit board. This helps to solve the problem that the device cannot position the circuit board.

The coating assembly is disposed outside the support plate 1. The fixing members 201 are fixedly connected to both sides of the bottom of the support plate 1. The outer shell 202 is fixedly connected to the middle of the bottom of the support plate 1. The motor 203 is fixedly connected inside the outer shell 202. The output end of the motor 203 is fixedly connected to a rotating member 204. The rotating member 204 is rotatably connected to a shaped member 205. The top of the shaped member 205 is rotatably connected to a sliding member 206. The middle of the top of the sliding member 206 is fixedly connected to a push plate 207. The two sides of the top of the sliding member 206 are fixedly connected to transmission rods 208. The top of the transmission rods 208 is rotatably connected to a positioning rod 209. The bottom of the positioning rods 209 is rotatably connected to a rotating wheel 210. By starting the motor 203, the rotating member 204 is driven to rotate, causing the shaped member 205 to pull the sliding member 206 closer together, thereby moving and pulling the transmission rods. 208 drives the positioning rod 209 to rotate, which in turn pushes the circuit board through the push plate 207 while positioning the circuit board with the rotating wheel 210. A groove is provided at the corresponding position of the fixing member 201 and the sliding member 206. The sliding member 206 is slidably connected to the outside of the fixing member 201. The fixing member 201 helps to support the movement of the sliding member 206. A hole is provided at the corresponding position of the support plate 1 and the positioning rod 209. The positioning rod 209 is rotatably connected inside the support plate 1. The positioning rod 209 helps to drive the rotating wheel 210 to position the circuit board. A groove is provided at the corresponding position of the support plate 1 and the sliding member 206. The sliding member 206 is slidably connected inside the support plate 1. The support plate 1 helps to limit the movement of the sliding member 206. The contact surface between the push plate 207 and the circuit board is made of rubber with anti-slip patterns. The push plate 207 helps to roughly position both sides of the circuit board.

[0021] Please see Figure 4 In this embodiment, the coating assembly includes a support leg 301, which is disposed outside the support plate 1. A second motor 302 is fixedly connected inside the support leg 301. A roller 303 is fixedly connected to the output end of the second motor 302. A conveyor belt 304 is connected to the outside of the roller 303. A support member 305 is disposed outside the conveyor belt 304.

When the circuit board is delivered to the corresponding position of the support member 305, the transport stops. After the circuit board is positioned, the coating device 306 is started to coat the circuit board. A groove is opened at the corresponding position of the support member 305 and the support plate 1. The support plate 1 is fixedly connected inside the support member 305. By setting the support member 305, it is helpful to support the support plate 1 and the coating device 306.

[0022] During operation, the second motor 302 drives the roller 303 to rotate, which in turn causes the conveyor belt 304 to transport the circuit board. When the circuit board is delivered to the corresponding position of the support 305, the transport stops, and the first motor 203 drives the rotating component 204 to rotate, causing the irregular component 205 to pull the sliding component 206 closer together.

After positioning the circuit board, the coating device 306 is started to coat the circuit board.

[0023] Through the above steps, the second motor 302 drives the roller 303 to rotate, which causes the conveyor belt 304 to transport the circuit board. When the circuit board is delivered to the corresponding position of the support 305, the transport stops, and the first motor 203 drives the rotating component 204 to rotate, causing the irregular component 205 to pull the sliding component 206 closer together. As a result, the movement pulls the transmission rod 208 to drive the positioning rod 209 to rotate. Then, the push plate 207 pushes the circuit board while the rotating wheel 210 positions the circuit board. After the circuit board is positioned, the coating device 306 is started to coat the circuit board, which helps to solve the problem that the device cannot position the circuit board.
