[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. The main structure of the present invention includes a processing box, a mounting back plate, a storage component, a transfer component and other structures. The processing box is divided into an etching chamber, a drying station, and a washing chamber by a partition plate. The transfer component arranged on the side of the mounting back plate can transfer the multiple keyboard built-in circuit boards on the storage component to the etching chamber, the washing chamber, and the drying station in sequence, so that the entire device integrates the etching, drying, and washing functions, greatly improving the production efficiency, reducing the plant space occupied by the equipment, avoiding the frequent manual transfer of workpieces between different devices, reducing the risk of human operation errors, and improving the stability of product quality. At the same time, the integrated design also reduces the manpower demand and labor intensity, and achieves a higher degree of production automation.

[0020] 2. The present invention is provided with a transfer assembly on the side after the back plate is installed. The transfer assembly is provided with only one electrical component, namely the transfer motor, and the remaining structure is all mechanical. Only through the transfer motor and the remaining mechanical structure, the keyboard built-in circuit board can be extended into the etching chamber, lifted from the etching chamber, moved horizontally along the drying station, and penetrated into the washing chamber. The complex movements of the washing chamber not only reduce the manufacturing cost and maintenance difficulty of the equipment, but also improve the reliability of the system and reduce the risk of downtime caused by electrical failure. At the same time, the application of mechanical structure makes the equipment operation more stable and precise, ensures the consistency of each processing step, and improves the overall production efficiency.

[0021] 3. The present invention is provided with a one-way shaking component at the drying station. The one-way shaking component will only be activated when the transfer component transfers multiple keyboard built-in circuit boards from the washing chamber to the drying station, and will not be activated when the transfer component transfers multiple keyboard built-in circuit boards from the etching chamber to the drying station, thereby saving a certain amount of electricity. When the multiple keyboard built-in circuit boards are transferred from the washing chamber to the drying station, the one-way shaking component knocks on the multiple keyboard built-in circuit boards to accelerate the falling of moisture attached to the surface of the keyboard built-in circuit boards, thereby reducing the energy consumption of the drying component at the drying station.

[0022] 4. One of the core components of the drying assembly arranged at the drying station of the present invention is a drying box, and the bottom of the drying box is rotatably connected to the drying station. The drying box can be flipped to a horizontal state when the storage assembly is unloaded, so that the workers can release the finely processed circuit boards on the storage assembly at the drying station.

[0046] The specific implementation steps and principles of the present invention are as follows:

[0047] In the initial state, the auxiliary wheel 41 is in the first vertical groove 24, the locking folding rod 10 is inserted into the fixed frame 9, the drying box 13 is in a vertical state, and the drying box 13 is connected to an external drying fan through the introduction tube 15.

When the driving column 43 moves transversely along the transverse groove 25, one end of the transverse column 311 will collide with multiple working balls 46, knocking and shaking off the moisture attached to the surfaces of multiple keyboard circuit boards. At the same time, the drying box 13 dries the multiple keyboard circuit boards. Finally, the worker detaches the locking folding rod 10 from the inside of the fixed frame 9, and the drying box 13 is flipped to a horizontal state. The triangular block 11 is overlapped to the side of the processing box 2, and the multiple keyboard circuit boards that have been finely processed are removed.

10. The method for processing a keyboard built-in circuit board according to claim 1, used for finishing equipment for a keyboard built-in circuit board according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: etching and washing, in the initial state, the auxiliary wheel (41) is in the first vertical groove (24), the locking folding rod (10) is inserted into the fixed frame (9), the drying box (13) is in a vertical state, and the drying box (13) is externally connected to a drying fan through an introduction tube (15). At this time, multiple sets of keyboard circuit boards are placed in multiple storage U frames (38). At this time, after the multiple keyboard circuit boards are etched in the etching chamber (201), the transfer motor (39) is started. The transfer motor (39) drives the auxiliary wheel (41) at one end of the driving column (43) to move along the first vertical groove (24), the transverse groove (25), and the second vertical groove (25) through the driving rod (40), and the multiple sets of keyboard circuit boards are transferred from the etching chamber (201) to the washing chamber (202) for rinsing. S2: Drying and unloading. After the keyboard circuit boards are washed in the washing chamber (202), the transfer motor (39) is reversed and the auxiliary wheel (41) at one end of the driving column (43) is driven by the driving rod (40) to move along the second vertical groove (24) and the transverse groove (25). The one-way shaking component will be activated to knock and shake off the moisture attached to the surfaces of the keyboard circuit boards. At the same time, the drying box (13) dries the keyboard circuit boards. Finally, the worker turns the drying box (13) to a horizontal state and removes the keyboard circuit boards that have been processed.
