[0025] Please refer to Figure 1 , the thick film circuit developing device 100 provided by the embodiment of the present utility model. The thick film circuit developing device 100 includes a developing box body 110. A conveying mechanism 130 is arranged in the developing box body 110. The conveying mechanism 130 is used to convey the thick film circuit substrate along the first horizontal direction. A support frame 111 and a driving mechanism are installed in the developing box body 110. A sliding rod 112 is horizontally slidably installed on the support frame 111 along the second horizontal direction. An installation frame 113 is installed on the sliding rod 112. A developing nozzle 114 is installed on the installation frame 113. The developing nozzle 114 is located above the conveying mechanism 130. The driving mechanism can drive the sliding rod 112 to reciprocate horizontally relative to the support frame 111.
[0026] When the thick film circuit substrate needs to be developed, the thick film circuit substrate is placed on the conveying mechanism 130. The conveying mechanism 130 conveys the thick film circuit substrate along the first horizontal direction. The developing nozzle 114 located above the conveying mechanism 130 sprays the developing solution on the surface of the substrate. At the same time, the driving mechanism drives the sliding rod 112 to reciprocate horizontally relative to the support frame 111 along the second horizontal direction, so that the developing solution can be evenly sprayed on the surface of the substrate, thereby reducing the probability of etching short circuits and open circuits and improving the yield.

The rotary driving member 116 drives the eccentric cam 117 to rotate, which can drive the sliding rod 112 to reciprocate horizontally relative to the support frame 111. In this embodiment, the rotary driving member 116 is a driving motor. The driving motor drives the eccentric cam 117 to rotate. And because the eccentric cam 117 is limited between the two abutting plates 118, the eccentric cam 117 drives the sliding rod 112 to reciprocate horizontally relative to the support frame 111.
[0028] For the thick film circuit developing device 100 provided by the embodiment of the present utility model, specifically, please refer to Figure 1, the mounting bracket 113 includes a mounting rod 119 which is arranged along the first horizontal direction.
