[0052] 2.

The functional areas between each mechanism are clearly defined, the coordination efficiency is high, and the structure is compact, small in size, and occupies little space. Compared with the feeding mechanism in the prior art, it has reduced the size while realizing more collaborative feeding functions. The overall design is L-shaped, and the length set on the equipment is shorter. While realizing multiple pushing feeding functions, it has improved feeding efficiency and brought higher economic benefits to enterprises.

[0053] 3. The tin plating mechanism of the tin plating equipment of the present invention is small in size and compact in structure. It uses linear slide rails and drag chains for movement, which is flexible and highly automated. It can be applied to the tin plating processing of most products.

This invention employs a multi-mechanism cooperative approach for material feeding, consisting of a feeding conveyor assembly, a feeding fixture tray moving assembly, a full-load fixture tray feeding assembly, an empty-load fixture tray loading assembly, and a tray handling mechanism. The feeding conveyor assembly transports a full-load fixture tray to the full-load fixture tray feeding assembly for feeding, while the empty-load fixture tray loading assembly automatically loads empty fixture trays.

There is no interference between components, effectively preventing product quality degradation during the feeding process and bringing better economic benefits to the enterprise.

[0055] 5. The tin plating equipment fixture positioning component of the present invention positions the fixture plate by means of the cooperation between the detection sheet metal and the slot-shaped switch. At the same time, infrared detection is performed in conjunction with the detection switch to ensure the accuracy and precision of the fixture plate's positioning above the water tank. No manual adjustment or manual positioning detection is required, which greatly saves manpower and significantly improves work efficiency. The present invention also uses a detection sheet metal fixing block to fix the relative position of the detection sheet metal and the slot-shaped switch, thereby effectively fixing the fixture plate and preventing its displacement, thus further ensuring the accuracy of positioning.
