Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 2 , Figure 3 In this embodiment of the invention, an automatic microneedle patching device includes a base 1. A top plate 3 is mounted on the upper side of the base 1 via a support frame 2. A first slider 13 is mounted on the lower side of the top plate 3 via a first lead screw 12. A transverse base 14 is mounted on the lower side of the first slider 13. A second slider 15 is mounted on the lower side of the transverse base 14 via a second lead screw 16. The first lead screw 12 is an X-axis lead screw, and the second lead screw 16 is a Y-axis lead screw. A fitting nozzle 19 is mounted on the lower side of the second slider 15 via a cylinder 17 and a mounting base 18. The device is driven by the first lead screw 12 and the second lead screw 16. The suction nozzle 19 is adjusted horizontally to pick up and put in microneedles. At the same time, a vision recognition system can be used to achieve precise material handling. A patching table 7 is provided on one side of the stand 2, and a clamp for positioning the patch product 11 is provided on the upper side of the patching table 7. The upper sides of both ends of the base 1 are rotatably equipped with take-up rollers 5 through the support frame 4, and a microneedle belt 6 is wound between the two take-up rollers 5. The take-up shaft at one end of the take-up roller 5 is connected to the take-up motor through the belt flywheel group, and the take-up motor is fixedly installed on the outer wall of the support frame 4, so as to facilitate the horizontal transfer of microneedles by rotating the take-up roller 5.

[0022] like Figure 1 and Figure 2 As shown, in order to improve the accuracy of the placement, the fixture also includes two third sliders 9 provided by the third lead screw 8, and each of the two third sliders 9 is provided with a positioning clamping plate 10 on its upper side. The third lead screw 8 includes a lead rod rotatably set in the upper limit slide groove of the placement table 7, and the outer sides of both ends of the lead rod are provided with two sets of opposite external threads. One end of the lead rod is connected to a servo motor, so that the two positioning clamping plates 10 are driven to move and adjust in opposite directions through the third lead screw 8, thereby enabling the product 11 to be placed to be laterally clamped and fixed, preventing the product 11 from moving during placement, which is beneficial to improving the accuracy of placement.

[0023] like Figure 2 and Figure 3 As shown, in order to prevent damage to the microneedles when holding the microneedle plate, multiple microneedle insertion holes 20 are provided on the lower side of the fitting nozzle 19, and an air pump is connected to one side of the multiple microneedle insertion holes 20 through an air tube. The microneedle insertion holes 20 can accommodate the microneedles when holding the microneedle sheet, preventing damage to the microneedles when holding the microneedle plate, and improving the safety and stability of holding and fixing.

[0024] The working principle and usage process of this utility model are as follows: In use, the microneedle tape 6 with multiple microneedle pieces bonded together is horizontally wound between two take-up rollers 5, and the patch product 11 is fixed on the patching table 7. The microneedle pieces are horizontally conveyed by rotating the take-up rollers 5. When the microneedle pieces are horizontally conveyed to the position directly below the bonding nozzle 19, the bonding nozzle 19 is driven by the cylinder 17 to move down onto the microneedle pieces. The bonding nozzle 19 picks up the microneedle pieces and removes them from the microneedle tape 6. Then, the microneedle tape is driven to move to the patching table 7 by the second lead screw 16 and the first lead screw 12. The bonding nozzle 19 is then driven by the cylinder 17 to move down and attach the microneedle pieces to the patch product 11 on the patching table 7. The bonding nozzle 19 is then released and reset. This cycle can be repeated to achieve continuous patching. Moreover, the operation is convenient and quick, and the patching efficiency is high.
