[0003] The circuit patterns on the circuit board are made using exposure imaging and development etching technology. Whether it is a multilayer PCB or a flexible circuit board, exposure imaging and development technology is used when making circuit patterns. Development is a process in industries such as printing, photocopying, copying, and blueprinting to make the image appear. It requires the circuit board to be sprayed with developing solution for processing.

[0004] Existing developing equipment has the following drawbacks in practical use:

[0005] When developing circuit boards by spraying developing solution, the circuit boards need to be fixed. However, the existing fixing mechanisms of developing equipment are mostly fixed by pressing and clamping, which is not convenient for adapting and locking the circuit boards according to different sizes. In addition, the circuit boards need to be sprayed with developing solution on both sides, which requires the workers to remove the circuit boards and manually flip them over to fix them, which reduces the processing efficiency.

[0030] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0031] In use, the circuit board is placed between the two clamping plates 8. The drive motor 13 is activated, causing the worm gear 16 to rotate. The worm gear 16 rotates the worm wheel 15, which in turn rotates the gear 14. The gear 14 then moves the two toothed plates 12 towards each other. This movement of the toothed plates 12 moves the two sliding plates 11 towards each other along the mounting cavity 10. The sliding plates 11 then move the two clamping plates 8 towards each other, thus clamping the circuit board. Then, the moving motor 19 is activated, causing the threaded rod 21 to rotate. Rotation 1 drives the moving block 22 to move along the sliding groove 20. The movement of the moving block 22 drives the diversion pipe 24 to move. At the same time, by starting the delivery pump in the storage tank 23, the delivery pump delivers the developer to the diversion pipe 24 through the connecting hose 26. The diversion pipe 24 diverts the developer to the nozzle 25 for spraying, thereby evenly spraying the developer onto the surface of the circuit board. Then, by starting the flip motor 6, the flip motor 6 drives the flip frame 7 to flip, thereby flipping the circuit board to the other side for spraying the developer. After spraying is completed, the flip motor 6 is started again to reset the flip frame 7, and the circuit board can be removed.
