Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The embodiment of the present application provides a device for adding chemicals to a developing line, thereby solving the problem in the prior art that, during the process of adding chemicals, it is usually not convenient to automatically and quickly mix the chemicals, which may easily lead to uneven distribution of the chemicals in the barrel, thereby reducing the accuracy of pH detection in the barrel and the pH accuracy of the chemicals in the barrel. If a motor is added for stirring, electronic components will be added, reducing system stability, which is not conducive to the quality of the chemicals and the production and processing of PCB boards.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] The utility model embodiment discloses a device for adding liquid medicine to a developing line. Figure 1-4 As shown, it includes a medicine storage cylinder 1, a cover plate 2 is provided on the medicine storage cylinder 1, a detection mechanism 3 is provided on the cover plate 2, the detection mechanism 3 includes a nut seat 301 fixedly connected to the cover plate 2, the internal thread of the nut seat 301 is connected to a screw head 302, and the screw head 302 is fixedly connected to a pH sensor 303. The detection mechanism 3 designed in the device has a simple structure, and the design of the nut seat 301 and the screw head 302 facilitates the rapid installation and fixation of the pH sensor 303.

[0025] A first rubber ring 3021 is provided between the inside of the nut seat 301 and the screw head 302, and a second rubber ring 3022 is provided between the top of the nut seat 301 and the screw head 302. The device is designed so that when the nut seat 301 and the screw head 302 are tightened, the first rubber ring 3021 and the second rubber ring 3022 are squeezed at the same time, forming a double seal at the interface position of the female seat 301 and the screw head 302, thereby ensuring that the pH sensor 303 is easy to disassemble and maintain and has good sealing at the installation position.

[0026] The bottom of the medicine storage barrel 1 is provided with an adding mechanism 4, which includes a base 402 fixedly connected to the bottom of the medicine storage barrel 1 and a delivery pump connecting pipe 401 fixedly connected to the base 402, a connecting pipe 403 fixedly connected between the base 402 and the medicine storage barrel 1, a turbine 404 rotatably connected inside the base 402, a transmission shaft 406 fixedly connected to the turbine 404, the transmission shaft 406 passes through the base 402 and the medicine storage barrel 1 and is fixedly connected to a stirring rod 407, and a bearing 405 for supporting the transmission shaft 406 is provided inside the base 402;

[0027] Through the design of the adding mechanism 4, the device utilizes the base 402, the delivery pump connecting pipe 401 and the connecting pipe 403 to facilitate the addition of liquid medicine into the inner cavity of the liquid medicine storage tube 1. During the adding process, the power of the liquid medicine fluid will drive the turbine 404 to rotate, the turbine 404 drives the transmission shaft 406 to rotate, and the transmission shaft 406 drives the stirring rod 407 to rotate, so that the liquid medicine is quickly stirred and mixed when entering the inner cavity of the liquid medicine storage tube 1, thereby ensuring that the detection mechanism 3 detects the pH value of the developing line liquid medicine accurately.

[0028] The inner cavity of the medicine storage tube 1 is provided with an arc-shaped baffle 304. Through the design of the arc-shaped baffle 304, during the dosing process, when the medicine inside the medicine storage tube 1 is stirred and mixed, the medicine will not directly act on the position of the PH sensor 303. At the same time, after mixing, it will contact the PH sensor 303, thereby ensuring that the detection accuracy of the PH sensor 303 is high.

[0029] A liquid taking tube 101 and an overflow tube 102 are fixedly connected to the side of the medicine storage tube 1. The liquid taking tube 101 is provided with a solenoid valve 1011, and the overflow tube 102 is provided with a one-way valve 1021. The design of the liquid taking tube 101 and the solenoid valve 1011 facilitates the taking out of the developing line medicine stored in the medicine storage tube 1. The design of the overflow tube 102 and the one-way valve 1021 can prevent excessive liquid addition inside the medicine storage tube 1. Excess developing line medicine will be discharged through the overflow tube 102. The one-way valve 1021 can prevent external impurities from entering the interior of the medicine storage tube 1.
