The indwelling needle is output from the first discharge port 150, ready for the next operation. The outer needle side cover is placed in the second vibrating plate 220. Through the vibration of the vibrating plate, the outer needle side cover gradually rises from the bottom to the top. The second track 240 guides the outer needle side cover from the vibrating plate to the second discharge port 250. The outer needle side cover is output from the second discharge port 250, ready for the next operation.

[0041] The first slider 340 slides on the first guide rail 330, driving the second mounting plate 350 to move horizontally, thereby realizing the horizontal movement of the entire vertical moving component 4. The first cylinder 410 drives the third mounting plate 420 to move up and down along the second guide rail 430, thereby realizing the vertical movement of the pressing component 450.

Through the fourth mounting plate 451, the third guide rail 454 and the third slider 455, the fifth mounting plate 456 drives the negative pressure clamp 458 to move downward. One negative pressure clamp 458 adsorbs the indwelling needle, and the other negative pressure clamp 458 adsorbs the outer needle side cover. Then the first guide rail 330 and the first slider move horizontally towards the conveying mechanism 5 with the adsorbed indwelling needle and the outer needle side cover.

[0042] First, the indwelling needle is placed above the disc 560 via the vertical moving component 4. The second cylinder 522 drives the clamping plate 525 to close, clamping the indwelling needle. Then, the horizontal component 3 continues to move horizontally, moving another negative pressure clamp 458 that adsorbs the outer needle side cover to above the indwelling needle. Next, the first cylinder 410 drives the third mounting plate 420 to move downward. Through the fourth mounting plate 451, the third guide rail 454, and the third slider 455, the fifth mounting plate 456 drives the negative pressure clamp 458 to move downward, pressing the outer needle side cover onto the indwelling needle. The spring 457 provides cushioning to ensure the smoothness and reliability of the pressing process. The disc 560 slides between the upper sliding plate 530 and the lower sliding plate 540 via a cylinder, moving the clamped insulin indwelling needle above the conveyor belt 550. The clamping plate 525 opens, releasing the insulin indwelling needle, which falls onto the conveyor belt 550. The conveyor belt 550 transports the insulin indwelling needle to the next storage location.

[0043] This insulin indwelling needle outer needle side cover assembly device has the following advantages: Vibration disc 120 and vibration disc 220 transport the indwelling needle and outer needle side cover from the bottom to the top through vibration, and then deliver them via a track; negative pressure clamp 458 uses negative pressure to adsorb the outer needle side cover, ensuring its stability and accuracy during the pressing process; the lateral movement component 3 and the vertical movement component 4 provide multi-axis motion capability, allowing the device to adapt to the operational needs of different positions and angles; the indwelling needle protection box 110 and the outer needle side cover protection box 210 provide physical protection to prevent dust and impurities from entering, while also protecting the safety of operators; the spring 457 provides cushioning during the pressing process, reducing impact and ensuring stability during the pressing process; the two negative pressure clamps 458 on both sides of the vertical movement component 4 ensure the consistency of the indwelling needle and outer needle side cover; automation and high precision ensure consistent assembly process for each product, improving product quality consistency and reliability, reducing scrap rate, and lowering production costs; the fast and efficient assembly process reduces the production cycle and improves the overall efficiency of the production line.
