With the development of social economy, the developing machine used for circuit board processing mainly uses ultraviolet light to irradiate the circuit on the film and print it on the circuit board, and then displays the pattern on the circuit board by brushing with developer.

[0003] For example, in the patent application with announcement number CN213938457U in the prior art, a collecting mechanism is provided at the bottom of the support column, a pushing mechanism is provided in the inner cavity of the collecting mechanism, a conveying mechanism is provided in the middle of the support column, a brushing mechanism is provided at the top of the support column, a spraying mechanism is provided at one end inside the brushing mechanism, and the brushing mechanism includes a fixed box, a second electric push rod is fixedly connected to the middle of the inner cavity of the fixed box, an output shaft is fixedly connected to the bottom of the second electric push rod, and a fixed block is fixedly connected to the bottom of the output shaft.

[0050] A transparent baffle 4 is fixedly mounted on the other side of the conveying frame 3 .

[0051] The transparent baffle 4 is provided to facilitate observation of the operation of the conveyor belt 361. The transparent baffle 4 is installed on the front of the conveyor frame 3 by screws.

[0052] When developing PCB boards of different sizes, the staff can first disassemble the transparent baffle 4, and then squeeze the spring telescopic rod 332, and then disassemble the conveyor belt 361, and then replace the conveyor belt 361 that is compatible with the PCB board that needs to be developed.

[0053] There are multiple mounting plates 66, and the tops of the multiple mounting plates 66 are fixedly mounted with second spring telescopic rods 65, the tops of the second spring telescopic rods 65 are fixedly mounted on the top of the inner side of the mounting frame 6, and the tops of the hollow frame 62 are fixedly mounted with a water pipe 61, and the input end of the water pipe 61 is fixedly mounted with a water pump 64, and the input end of the water pump 64 is arranged on the inner side of the water tank 1.

[0057] The bottom of the loading frame 7 is arranged on the top of the conveyor belt 361 .

[0058] The working principle of a PCB circuit board developing device provided by the present invention is as follows:

[0059] When in use, the PCB board to be developed is placed on the inner side of the loading frame 7, and the height of the loading frame 7 is adjusted so that the bottom of the loading frame 7 is at the top of the conveyor belt 361. Then, the drive motor 34 is started, and the drive motor 34 drives the conveyor belt 361 to move through the rotating shaft 35. When the groove 363 moves to the bottom of the loading frame 7, the PCB board will automatically fall to the inner side of the groove 363. At this time, the water pump 64 is started to extract the developer inside the water tank 1, and then spray it on the PCB board through the water pipe 61, the hollow frame 62 and the nozzle 63. At this time, it is transported through the conveyor belt 361 and the PCB board is moved to the bottom of the brush body 67, so that the brush body 67 scrubs the PCB board. When it moves to one end of the conveyor belt 361, the conveyor belt 361 is deformed due to the rotating shaft 35, so that the PCB board can automatically move out of the inner side of the groove 363 and fall on the unloading plate 5, so as to unload.

[0060] Compared with the related art, the PCB circuit board developing device provided by the present invention has the following beneficial effects:

[0061] By cooperating with each other through structures such as the conveying frame 3, the driving motor 34, the rotating shaft 34, the conveying assembly 36, the unloading plate 5 and the loading frame 7, when the conveyor belt 361 is moved, the PCB board can automatically fall from the inner side of the loading frame 7 to the inner side of the groove 363, thereby automatically loading the material, which not only reduces the operation of the staff, but also improves the production efficiency. In addition, the stability of the PCB board placement is increased by limiting the PCB board through the groove 363.

A connecting rod 82 is also fixedly installed between the collecting frame 8 and the water tank 1.

[0065] A filter plate 83 is fixedly mounted on the inner side of the collecting frame 8 .

[0066] The working principle of a PCB circuit board developing device provided by the present invention is as follows:

[0067] When in use, the PCB board that slides off the blanking plate 5 will fall to the inner side of the collection frame 8 and be located above the filter plate 83. Then, the excess developer on the PCB board will flow back into the inner side of the water tank 1 through the connecting pipe 81.

[0068] Compared with the related art, the PCB circuit board developing device provided by the present invention has the following beneficial effects:

The filter component 9 includes a baffle 91 and a filter frame 92, and the baffle 91 is arranged at the top of the water tank 1, and the filter frame 92 is fixedly installed at the bottom of the baffle 91.

[0073] The filter frame 92 is a square structure made of metal filter material and has an entrance at the top. The baffle 91 is installed on the top of the filter frame 92 so that the bottom of the baffle 91 abuts against the top of the water tank 1, thereby facilitating the installation of the filter frame 92.

[0074] The working principle of a PCB circuit board developing device provided by the present invention is as follows:

[0075] When in use, the developer after scrubbing flows back into the top of the water tank 1, and then flows into the inner side of the filter frame 92 along the inclined surface of the top of the water tank 1, so that impurities are accumulated on the inner side of the filter frame 92, so as to facilitate subsequent processing by the user.

[0076] Compared with the related art, the PCB circuit board developing device provided by the present invention has the following beneficial effects:

[0077] By the cooperation between the baffle 91 and the filter frame 92 and other structures, impurities in the developer can be filtered and collected on the inner side of the filter frame 92 for subsequent processing by the user.
