The upper end of the support base 1 and outside the support platform 4 is in contact with a moving frame 6.

[0022] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , A developing mechanism 7 is jointly arranged on the moving frame 6, the mounting frame 2 and the support base 1. The developing mechanism 7 includes a developer delivery pipe 71. The horizontal part of the moving frame 6 is fixedly connected with the developer delivery pipe 71. The lower end of the developer delivery pipe 71 is fixedly connected with a connecting pipe 72. The lower side of the connecting pipe 72 is fixedly connected with an atomizing nozzle 73. On the surface of the support platform 4, there is a chute 74. The inner side wall of the chute 74 is fixedly connected with a guide rod 75. The outside of the guide rod 75 is slidably sleeved with a slider 76. The slider 76 is slidably connected with the chute 74. The slider 76 is fixedly connected with the moving frame 6. The upper end of the support base 1 and on the left side of the moving frame 6 is fixedly connected with a fixing plate 77. In the middle of the right end of the support base 1, there is a support plate 79. Inside the support plate 79, there is a winding roller 790 installed through a bearing. On the surface of the winding roller 790, there is a traction wire 791. The other end of the traction wire 791 is fixedly connected with the vertical part of the moving frame 6. The outside of the end shaft of the winding roller 790 is fixedly sleeved with a gear one 792. On the front surface of the mounting frame 2, there is a mounting plate 793 fixedly connected. On the front surface of the mounting plate 793, there is a servo motor 795 fixedly installed. The outside of the output shaft of the servo motor 795 is fixedly sleeved with a gear two 796. The gear two 796 meshes with the gear one 792. Through the settings of the developer delivery pipe 71 and the atomizing nozzle 73, the developer can be atomized and sprayed. Under the precise control of the servo motor 795 and with the cooperation of structures such as the gear two 796 and the gear one 792, the winding roller 790 can rotate precisely, and then the traction wire 791 can be wound to pull the moving frame 6 to move, thereby driving the atomizing nozzle 73 to spray the developer dynamically, improving work efficiency.

[0023] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4, there are multiple atomizing nozzles 73, and the multiple atomizing nozzles 73 are evenly distributed on the connecting pipe 72. Through the setting of the atomizing nozzles 73, the developer can be atomized and sprayed. There are two chutes 74, and the two chutes 74 are symmetrically distributed on the support table 4. Through the setting of the chutes 74, it is convenient for the subsequent placement and use of structures such as the slider 76. The right end of the fixing plate 77 is welded with a spring 78, and the other end of the spring 78 is welded to the vertical part of the moving frame 6. Through the setting of the spring 78, the moving frame 6 can be connected and used.

[0024] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , there are two traction lines 791, and the two traction lines 791 are symmetrically distributed on the winding roller 790. Through the setting of the traction lines 791, the moving frame 6 can be tractioned.

Under the action of the developer delivery pipe 71, the developer can be delivered to the connecting pipe 72, and in cooperation with the action of the atomizing nozzles 73, the developer can be atomized and sprayed.

[0026] Start the servo motor 795 to drive the output shaft to rotate forward, so as to drive the second gear 796 to rotate. In the meshing relationship, the second gear 796 drives the first gear 792 to rotate, and then drives the winding roller 790 to rotate precisely, wind the traction line 791, and then pull the moving frame 6 to move. When the moving frame 6 moves, it can drive the slider 76 to move along the surface of the guide rod 75 to ensure the stable movement of the moving frame 6. Under the action of the fixing plate 77, the spring 78 deforms.

[0027] During this process, when the moving frame 6 moves, it can drive the developer delivery pipe 71 to move, and then drive the atomizing nozzles 73 to move, so that the atomizing nozzles 73 perform mobile atomizing spraying on the developer, improving the working efficiency of the developing process of the circuit board body 5. Start the servo motor 795 to drive the output shaft to rotate reversely, so as to drive the second gear 796 to rotate. Similarly, the winding roller 790 can pay out the traction line 791, and in cooperation with the deformation of the spring 78, it can pull the moving frame 6 to move, and finally make the moving frame 6 reset, which is convenient for the subsequent developing process of the circuit board body 5.
