Technical Field

[0001] The invention relates to the field of needle sleeve machines, in particular to an automatic needle sleeve placing machine. Background Art

[0002] A syringe is a common medical device used in medicine to inject patients. It can be used for intravenous injection, subcutaneous injection, intraperitoneal injection, or to draw drugs, etc. The needle is a hollow metal needle that can be freely loaded and unloaded at the head of the syringe. For the sake of safety and hygiene, a needle cover is usually installed at one end of the needle during production to prevent the needle from being contaminated during transportation. Usually, the needle cover is produced separately from the needle. After the needle cover is produced, it is usually placed in a specific plate hole for storage.

[0003] During the placement process of the above structure, the staff usually places it manually. After wearing sterile gloves, the staff takes multiple needle sleeves through the plate, and then manually inserts them into the holes of the plate, and fills the holes of the plate one by one. Then, the plate is replaced and multiple needle sleeves are taken again. The above actions are repeated until the installation and placement of all needle sleeves are completed.

[0004] Since the above structure is difficult to control manually during use, the needle sleeve is prone to bending and unevenness. At the same time, workers may easily suffer eye fatigue when installing the needle sleeve for a long time, which reduces the efficiency of needle sleeve placement and increases the workload of workers. Summary of the invention

DETAILED DESCRIPTION

[0038] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] The following describes an embodiment of the present invention based on its overall structure.

[0040] An automatic needle sleeve placing machine, such as Figure 1-Figure 6 As shown, it includes a workbench 1, a plate body 2, a vibration mechanism 3, a material taking mechanism 4, a sliding mechanism and a material discharging mechanism. The plate body 2 is installed on the top of the workbench 1, and the material needle sleeve is placed in the vibration plate 301 for vibration. The needle sleeve is arranged in order in the specified direction to the material chuck 406 through the action of the vibration component. The controller is started to move the discharge rod 12 to the specified hole position through the cooperation of the X-axis module 6 and the Y-axis module 8, and the discharge rod 1 is moved downward by the action of the discharge cylinder 13. 2, waiting for discharge, while when the feeding detection switch 407 detects that the needle sleeve material is in place, the clamping cylinder 404 clamps the needle sleeve, and then the lifting cylinder 402 lifts it, and drives the needle sleeve to move to one side to the top of the feeding assembly 401 through the cooperation with the shift cylinder 403, and the clamping cylinder 404 releases the needle sleeve to drop into the feeding assembly 401. One end of the feeding assembly 401 is provided with an external air nozzle 405, and the needle sleeve is blown into the feeding pipe 5 through the external air nozzle 405. The other end is connected to the through-hole block 9. When the material passes through the through-hole block 9 and falls into the discharge rod 12, the discharge detection optical fibers 14 on both sides detect the needle sleeve material, and the discharge cylinder 13 rises, so that the needle sleeve automatically falls into the hole of the plate body 2, and moves to the next group of holes through the cooperation of the X-axis module 6 and the Y-axis module 8. A latching tooth 16 is provided on the top of the Y-axis slide 802, and the transmission gear 15 on one side of the X-axis slide 602 cooperates with it to drive the transmission shaft 11 to rotate, and the transmission shaft 11 One end is connected to a corrugated winding drum 10, and a corrugated tube 7 is wound around its outer wall. The corrugated tube 7 is a DN20 plastic-coated hose, which is not prone to folding during the winding process. Both ends of the corrugated tube 7 are connected to a feeding tube 5, so that when the device moves on the Y axis, the corrugated tube 7 can be retracted and released, so that the feeding tube 5 is always in a straight state, ensuring that the material inside it can be transported stably, preventing the feeding tube 5 from folding when it is too long, and ensuring the high efficiency of the subsequent feeding of the feeding tube 5.

[0041] Based on the above structure, in this embodiment, the Y-axis module 8 includes a Y-axis linear guide 801 and a Y-axis slide 802, the Y-axis linear guide 801 is located on the top of the workbench 1, and the Y-axis slide 802 is slidably connected thereto, and the X-axis module 6 includes an X-axis linear guide 601 and an X-axis slide 602, the X-axis linear guide 601 is located on the top of the Y-axis slide 802, and the X-axis slide 602 is slidably connected thereto.

[0042] The material taking mechanism 4 and the vibration mechanism 3 are at the same level, which makes it easy for the material taking mechanism 4 to take and place the needle sleeve, thereby improving its convenience and expanding its scope of application.

[0043] On the basis of the above structure, in this embodiment, the vibration mechanism 3 includes a vibration component 302 and a vibration disk 301 , and the vibration component 302 drives the vibration disk 301 to vibrate at high frequency, so that the internal needle sleeves are orderly arranged inside the material chuck 406 .

[0044] This embodiment further provides a support sleeve 17 provided on the transmission shaft 11, and the support sleeve 17 is located on the top of the Y-axis slide plate 802, and the transmission shaft 11 is supported by the support sleeve 17 to prevent it from tilting when rotating.

[0045] When in use, the needle sleeve is placed in the vibration mechanism 3 and arranged in order in the material chuck 406. The discharge rod 12 is moved to the designated hole position of the plate body 2 through the cooperation of the X-axis module 6 and the Y-axis module 8, and the discharge rod 12 is inserted into the hole position. The needle sleeve is clamped by the cooperation of the clamping cylinder 404 and the lifting cylinder 402, and then the shifting cylinder 403 drives it to move to one side so that it falls into the feeding component 401. One end of the feeding component 401 blows the material into the feeding pipe 5 through the external air nozzle 405. The other end of the feeding pipe 5 is connected to the through-hole block 9. When the discharge detection optical fiber 14 detects the material in the discharge rod 12, the discharge cylinder 13 rises, and then moves to the next hole position through the cooperation of the X-axis module 6 and the Y-axis module 8 to complete an action process.

[0046] The present invention creatively changes the needle sleeve insertion into an automatic insertion, thus avoiding the traditional manual insertion by the staff. In the prior art, the manual insertion is too time-consuming, and long-time work can easily lead to eye fatigue of the staff, and the needle sleeve is prone to bending and unevenness. In this solution, the automatic insertion is completed through the cooperation of the material taking mechanism 4 and the material discharging rod 12. This process does not require manual operation to take materials, which speeds up the work efficiency of the staff and reduces their workload.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
