[0035] Through the implementation of the above technical solution, the multi-station high-efficiency spraying production line is used as follows: first, the unloaded loading fixture 2 is moved to the bottom of the loading unit 5 through the transmission unit 1, and then the workpiece 6 to be sprayed is sleeved on the corresponding positioning column 206 through the loading unit 5, and then the fully loaded loading fixture 2 is moved to the bottom of the spraying unit 3 through the transmission unit 1, and then the workpiece 6 to be sprayed is grabbed into the spraying cavity for spraying through the spraying unit 3, and finally the workpiece that has been sprayed is taken out from the loading fixture 2 through the unloading unit 4. Through the multiple loading fixtures 2 arranged on the transmission unit 1, multiple workpieces 6 to be sprayed can be sprayed in sequence, and each loading fixture 2 is loaded with multiple workpieces 6 to be sprayed through the arranged positioning column 206, so that the spraying of multiple workpieces 6 to be sprayed can be realized in time periods, and multiple sleeve-shaped workpieces 6 to be sprayed can be sprayed online, and the assembly, spraying, transmission and unloading are integrated to optimize the production line structure.

The plurality of stop bars 203 are connected end to end, and when the movable block 202 moves upward, a shield is formed between the movable block 202 and the bottom opening of the spray chamber.

[0038] In this embodiment, clamping grooves 204 are provided on the left and right sides of the movable block 202, and the spray unit 3 includes a spray box 301 with an open bottom, and clamping structures are symmetrically provided on the left and right sides of the spray box 301; the clamping structure includes a horizontal plate 302, and a telescopic plate 303 installed under the horizontal plate 302, a fixed splint 305 is fixedly connected to the bottom of the telescopic plate 303, a movable splint 306 is provided on the inner side of the fixed splint 305, a first cylinder 304 is installed on the fixed splint 305, the shaft of the first cylinder 304 is connected to the movable splint 306, and a clamping column 307 that can extend to the corresponding clamping groove 204 is provided on the inner side of the movable splint 306.

[0039] Through such an arrangement, when the loading fixture 2 loaded with the workpiece 6 to be sprayed moves to the bottom of the spray box 301, the transmission unit 1 stops moving, and the clamping structures on both sides are used to clamp and move up the multiple movable blocks 202, and the multiple workpieces to be sprayed 6 are moved into the spray chamber for spraying. The specific clamping method is: the clamping column 307 is moved to the clamping position or moved out to the clamping position by lifting and lowering the telescopic plate 303, and then the movable clamping plate 306 is driven to move by the shaft extension of the first cylinder 304, and the multiple clamping columns 307 are driven to move to or out of the clamping groove 204.
