[0023] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0024] This specific embodiment involves a nickel-palladium-gold rack, such as Figure 1 and Figure 2 As shown, it includes a frame 100, and a PCB board is placed in the frame 100. In order to prevent the metal frame 100 from reacting with chemical nickel palladium gold, chemical nickel palladium gold is plated on the frame 100. The frame 100 is composed of a fixed rod 110 and a fixed frame 120 arranged at intervals. Therefore, the frame 100 can form a space for accommodating the PCB board, and the space is a placement area for placing the PCB board. During the use of the frame 100, an opening 130 is left on one side for the PCB board to be placed in the frame 100 through the opening 130. The PCB board is in a sheet shape and is distributed at intervals. The assembly frame 500 wraps the PCB board to fix the PCB board therein. The assembly frame 500 is used to prevent the PCB board from falling from the gap of the frame 100 during the processing. A coating layer made of Teflon is provided on the frame 100. The coating layer can be a rubber coating wrapped on the surface of the frame 100 after the frame 100 is manufactured, and the rubber coating is used to prevent the frame 100 from reacting with the liquid medicine.

[0025] like Figure 1 and Figure 3 As shown, the top surface of the frame 100 is provided with two groups of hooks 200 for fixing the frame 100. The frame 100 is fixed to the crossbeam by the hooks 200. When the frame 100 is not needed, the frame 100 can be removed by the hooks 200. The hook 200 includes a fixing portion 210 and a bending portion 220, and the fixing portion 210 is fixed to the top surface of the frame 100. The fixing portion 210 is fixed to the fixing rod 110 by welding. The fixing portion 210 is in the form of a sheet. The bending portion 220 is integrally formed on the top surface of the fixing portion 210, and a barb shape is formed between the bending portion 220 and the fixing portion 210. A cavity 230 is formed between the bending portion 220 and the fixing portion 210. When the frame 100 is hung on the crossbeam, the crossbeam is located in the cavity 230.

[0026] like Figure 1 and Figure 4As shown, the frame 100 is also provided with a limiting component for fixing the PCB board, because the PCB board needs to be continuously washed with water, and during the washing process, the PCB board will be shaken by the force of the washing liquid, so the PCB board needs a limiting component to limit and fix. The limiting component includes a lock hook 300, which is inserted into the placement area and contacts the PCB board. The function of the lock hook 300 is: when the PCB is placed in the frame 100, the opening 130 is blocked by the lock hook 300, thereby preventing the PCB board from escaping from the opening 130 during the washing process. The lock hook 300 is divided into a locking portion 310 buckled on the horizontal bar and a connecting portion 320 formed with a bend. The connecting portion 320 is a stainless steel pipe and is formed with a bend. The locking portion 310 includes a long strip-shaped gear rod 311 and a curved rod 312 with an arc-shaped cross section. The curved rod 312 is buckled on the fixing rod 110. The gear lever 311 abuts against the fixed lever 110, thereby preventing the lock hook 300 from shaking during the washing process. The curved lever 312 is buckled on the fixed lever 110 and connected to the connecting portion 320. Both ends of the connecting portion 320 are integrally formed with the buckling portion 310, and the other end of each buckling portion 310 is integrally formed with the gear lever 311.

[0027] like Figure 1 and Figure 2 As shown, the limiting component also includes a separator 400 for separating the PCB boards. The function of the separator 400 is: the chemical reaction in the PCB board needs to rely on the disturbance of the liquid medicine and the circulation diffusion to maintain the uniformity and stability of the reaction. The separator 400 can be used to avoid the PCB boards from overlapping in the liquid medicine tank, thereby improving the efficiency of the chemical reaction. The separator 400 is preferably a Teflon wire, and can also be a stick-shaped structure, a strip structure or other complex structures. The separator 400 is inserted between the PCB boards. The fixing rod 110 located on the top surface of the fixing frame 120 is provided with a through hole 111 for the separator 400 to pass through, and the fixing rod 110 located on the bottom surface of the fixing frame 120 is provided with a blind hole 112 for fixing the separator 400. The separator 400 is fixed by the mutual cooperation between the through hole 111 and the blind hole 112. The separator 400 is distributed at intervals along with the interval distribution of the through holes 111.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
