Description

Technical Field

[0001] The present invention relates to the technical field of assembling anti-pricking steel needles, and specifically to an anti-pricking steel needle assembly line. Background Art

[0002] For the anti-pricking steel needle, its structure is shown in Figure 1 , which includes a steel needle a, an isolation plug b, a safety joint c, and a steel needle base d. The structure of the safety joint is shown in Figure 2 , which includes a plastic shell e and a spring piece f. It is necessary to place the spring piece f in the positioning position of the plastic shell e and then combine them to form the safety joint c. The existing assembly is all in a straight-line production line operation, which requires a large amount of space. And in actual assembly, the single-piece assembly operation makes the production efficiency low. And after assembly, it is necessary to transfer to an external lubrication device for lubricating the isolation plug and the overall structure, which cannot meet the rapid production requirements. Summary of the Invention

[0006] And a sub-base on which a fourth stepping rotary disk is arranged;

[0007] On the rotary ring of the main stepping rotary disk, first carriers are arranged at intervals. At least two steel needles and their subsequent assembly parts are positioned and clamped on the first carriers. On the rotary ring of the main stepping rotary disk, a steel needle feeding station, a steel needle flattening station, an angle rotation station, an isolation plug feeding and starting assembly station, a safety joint feeding and assembly station, a safety joint lubrication station, a needle base feeding and assembly station, an angle re-inspection station, an isolation plug lubrication station, an isolation plug sliding station, a puncture assembly lubrication and discharging station are sequentially arranged;
