Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a circuit board surface coating device. Background Art

[0002] Circuit board coating (PCB Coating) refers to coating a layer of protective material on the surface of a printed circuit board to improve its environmental resistance and reliability. The main purpose of coating is to protect the circuit board from factors such as moisture, dust, chemicals, and temperature changes, thereby extending the service life of the device.

[0003] In the prior art, when coating the surface of a circuit board, manual brushing or manual spraying is usually adopted. Both of these methods are operated manually, which not only has the problems of low coating efficiency and high labor intensity, but also may have the problem of uneven coating.

[0004] In the invention with the application number: CN202210561551.X and the publication number: CN114667000A, a circuit board surface coating device for circuit board production is disclosed. When in use, after placing the circuit board on the placement rack, the PLC controller starts the cylinder to push the upper baffle to limit the circuit board, then starts the motor to drive the circuit board to flip, and then starts the water pump to coat the front surface of the circuit board to achieve the fixing and flipping operations of the circuit board.

[0067] During use, the dried circuit board is moved into the collection box 243 by moving the clamping member 22, and then the dried circuit board falls on the flexible pad 245, and then slides out through the discharge inclined plate 244 and can be transferred manually.

[0068] The flexible pad 245 can adopt a flexible rubber material in the prior art that can achieve the functions of the present utility model.

[0069] As Figure 1As shown, specifically, during use, first select a suitable placement table 211 according to the size of the circuit board to be coated, then fix the placement table 211 to the placement base 210 with bolts, then insert the circuit board to be coated into the slot 212 on the placement table 211, then drive the threaded rotating rod 217 through the drive motor 216, so that the sliding mounting block 219 moves to one side inside the horizontal sliding track 218 and forms a cooperation with the placement table 211. Then drive the sliding limit block 221 to move downward in the vertical sliding track 220 through the cylinder 223. At the same time, drive a pair of sliding connection blocks 226 to move through a pair of pneumatic telescopic rods 225, so as to drive a pair of clamping heads 227 to clamp both sides of the upper end of the circuit board to be coated. Then drive the sliding limit block 221 to move upward in the vertical sliding track 220 through the cylinder 223, and then drive the threaded rotating rod 217 through the drive motor 216, so that the sliding mounting block 219 moves in the horizontal sliding track 218;

[0070] When the sliding mounting block 219 moves above the spraying box body 200, the drive motor 216 stops. Drive the sliding limit block 221 to move downward in the vertical sliding track 220 through the cylinder 223, so that the circuit board to be coated is located between the four spraying pipes 205. Then open the solenoid valve 208, pump the spraying material in the storage tank 201 into the conveying pipe 202 through the conveying pump 209. The spraying material in the conveying pipe 202 is input into a pair of conveying branch pipes 204 through the connecting pipe 203, and then sprayed out by the two groups of spraying pipes 205, so that the spraying material is sprayed on the surface of the circuit board to be coated. Then drive the sliding limit block 221 to move upward in the vertical sliding track 220 through the cylinder 223, and then drive the threaded rotating rod 217 through the drive motor 216, so that the sliding mounting block 219 moves in the horizontal sliding track 218;

[0071] When the sliding mounting block 219 moves above the drying box body 233, the drive motor 216 stops. Drive the sliding limit block 221 to move downward in the vertical sliding track 220 through the cylinder 223, so that the circuit board is located inside the drying box body 233. Then send air into the drying box body 233 through several fans 238. At the same time, heat the incoming air through several heating elements 237 to heat and dry the circuit board. Then drive the sliding limit block 221 to move upward in the vertical sliding track 220 through the cylinder 223, and then drive the threaded rotating rod 217 through the drive motor 216, so that the sliding mounting block 219 moves in the horizontal sliding track 218;

[0072] When the sliding mounting block 219 moves above the collection box 243, the driving motor 216 stops. The sliding limit block 221 is driven by the cylinder 223 to move downward within the vertical sliding track 220. At the same time, a pair of sliding connection blocks 226 are driven by a pair of pneumatic telescopic rods 225 to move, thereby driving a pair of clamping heads 227 to release the dried circuit board. The circuit board falls onto the flexible pad 245 and then slides out through the discharge inclined plate 244, and then can be transferred manually to complete the coating of the circuit board. After completing the coating of the circuit board, the sliding limit block 221 is driven by the cylinder 223 to move upward within the vertical sliding track 220 to reset.

[0073] Working principle of the present utility model:

[0074] The present utility model realizes the coating on the surface of the circuit board by setting a placing member 21, a moving clamping member 22, a spraying member 23, a drying member 24, and a collecting member 25. During use, the moving clamping member 22 clamps the circuit board to be coated, and the circuit board to be coated passes through the placing member 21, the spraying member 23, the drying member 24, and the collecting member 25 in sequence to complete the surface coating of the circuit board.

[0075] During the spraying process, first, the moving clamping member 22 moves the circuit board to be coated from the placing member 21 into the spraying member 23. Then, the solenoid valve 208 is opened, and the spraying material in the storage tank 201 is pumped into the conveying pipe 202 by the conveying pump 209. The spraying material in the conveying pipe 202 is input into a pair of conveying branch pipes 204 through the connecting pipe 203, and then sprayed out by two groups of spraying pipes 205, so that the spraying material is sprayed on the surface of the circuit board to be coated. Then, the moving clamping member 22 transfers the circuit board with the spraying material coated on its surface into the drying member 24 for drying, and then the moving clamping member 22 transfers the dried circuit board into the collecting member 25 for collection, thereby completing the surface coating of the circuit board.

[0076] The above-described embodiments only represent the specific implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation of the patent scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
