Therefore, the entire impregnation process still takes a long time, which leads to material accumulation in the next step or a pause in waiting for materials. Utility Model Content

[0026] Specifically, the first motor 5 drives the screw rod 3 to rotate, thereby driving the threaded block 4 threadedly connected thereto to move, and the second motor 16 drives the rotating roller 7 to rotate. During the rotation of the rotating roller 7, the clamp 9 installed at the end of the connecting rod 8 is driven to be inserted into the immersion tank 10. Since too many immersion tanks 10 are installed on the top of the base 1, the clamp 9 can continuously enter each immersion tank 10 for immersion by moving the first mounting plate 6, thereby improving work efficiency.
[0027] Furthermore, the rotary impregnation assembly includes a rotary roller 7, a connecting rod 8 and a clamp 9. The rotary roller 7 is rotatably mounted outside the first mounting plate 6, and multiple connecting rods 8 are mounted on the outer sides of the rotary roller 7.

[0029] Specifically, when the first mounting plate 6 moves laterally, it drives the rotating roller 7 to move laterally. When the rotating roller 7 moves laterally, it drives the second mounting plate 15 to move laterally. The convex body 14 installed at the bottom of the second mounting plate 15 slides laterally in the concave groove 13, thereby guiding the laterally moving second mounting plate 15.
