Description

Technical Field

[0001] This utility model belongs to the field of medical devices, and in particular relates to an automatic needle loading device for medical indwelling needles. Background Technology

[0002] The core structure of an indwelling needle includes a stainless steel needle core and a flexible catheter that can be left in the blood vessel. The stainless steel needle core typically needs to be crimped into the needle hub at the tip of the catheter in a specific direction. To improve production efficiency and ensure hygiene, automated machines are currently used to assemble the stainless steel needle core and needle hub. A drawback of traditional automated needle loading equipment is that the needle feeding mechanism has difficulty conveying the stainless steel needle core in the same direction, requiring subsequent correction. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an automatic needle loading device for medical indwelling needles that can transmit stainless steel puncture needle cores in the same direction.

[0004] To solve the above problems, the technical solution adopted by this utility model includes: a needle feeding mechanism, which includes a frame, a lifting device at the lower end of the frame, and a needle taking device at the upper end of the frame. The lifting device includes a horizontally arranged lifting plate, a needle pushing plate arranged at a 90° angle with the lifting plate, a first cylinder that drives the lifting plate to move back and forth, a second cylinder that drives the needle pushing plate to rise and fall, and a third cylinder that drives the first cylinder to rise and fall. The front end of the lifting plate is provided with a first clearance groove adapted to the needle pushing plate, and oblique grooves and arc grooves are respectively provided on both sides of the first clearance groove.

[0005] The front end of the pusher plate is provided with a baffle, and the pusher plate is close to the side of the baffle.

[0006] The pusher plate has an inclined needle bucket on one side, and the front end of the needle bucket has a needle outlet for a single needle to slide out. The needle outlet is close to the baffle, and the middle of the needle outlet has a second clearance groove for the pusher plate to extend into.

[0007] The top of the pusher plate is provided with a positioning groove.

[0008] The needle-retrieving device includes a first pneumatic gripper and a second pneumatic gripper. The first pneumatic gripper is mounted on the rotating arm of a rotary cylinder, and the second pneumatic gripper is mounted on an XY-axis slide.

[0009] A transfer platform is provided between the first pneumatic gripper and the second pneumatic gripper. The end face of the transfer platform is provided with a vertical pinhole. A fourth cylinder is provided on the rotary cylinder to drive it to rise and fall.

[0010] The advantages of the automatic needle loading device for medical indwelling needles of this utility model are as follows: 1. When both ends of the stainless steel puncture needle core enter the inclined groove and the arc groove, they will be automatically positioned in the same direction, so that the stainless steel puncture needle core can be conveyed in the same direction; 2. The overall structure is simple and the reliability is good.

[0011] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0017] Reference Figure 1-5 As shown, the automatic needle loading device for medical indwelling needles of this utility model includes a needle delivery mechanism. The needle delivery mechanism includes a frame 1, a lifting device 2 located at the lower end of the frame 1, and a needle retrieval device 3 located at the upper end of the frame 1. The lifting device 2 includes a horizontally arranged lifting plate 4, a needle pushing plate 5 arranged at a 90° angle to the front end of the lifting plate 4, a first cylinder 6 that drives the lifting plate 4 to move back and forth, a second cylinder 7 that drives the needle pushing plate 5 to rise and fall, and a third cylinder 24 that drives the first cylinder 6 to rise and fall. The front end of the lifting plate 4 is provided with a first clearance groove 8 adapted to the needle pushing plate 5, and oblique grooves 9 and arc-shaped grooves 10 are respectively provided on both sides of the first clearance groove 8. After the stainless steel puncture needle core 25 is lifted upwards by the pusher plate 5, the lifting plate 4 first moves forward via the first cylinder 6 and inserts below the stainless steel puncture needle core 25, aligning the inclined groove 9 and the arc-shaped groove 10 with the two ends of the stainless steel puncture needle core 25. Then, it moves upwards via the third cylinder 24, lifting the stainless steel puncture needle core 25 upwards. Because the arc-shaped surface of the stainless steel puncture needle core 25 is not easily positioned with the inclined groove 9 and the arc-shaped groove 10, it will roll until the inclined surface of the needle tip of the stainless steel puncture needle core 25 fits against the inclined groove 9, completing the positioning. This allows the needle retrieval device 3 to extract the needle in the same direction.

[0018] Preferably, the front end of the pusher plate 5 is provided with a baffle 11, and the pusher plate 5 is close to the side of the baffle 11 to prevent the stainless steel puncture needle core 25 from falling off during the lifting process.

[0019] Preferably, the pusher plate 5 has an inclined needle hopper 12 on one side, and the front end of the needle hopper 12 has a needle outlet 13 for a single needle to slide out. The needle outlet 13 is close to the baffle 11, and the middle of the needle outlet 13 has a second clearance groove 14 for the pusher plate 5 to extend into. With the above structure, when the pusher plate 5 is lifted upward from below the needle hopper 12, a stainless steel puncture needle core can be extracted from the front end of the needle hopper 12, thereby realizing the connection and supply of stainless steel puncture needle cores.

[0020] Preferably, the top of the pusher plate 5 is provided with a positioning groove 15. During lifting, the stainless steel puncture needle core is placed in the positioning groove 15 to prevent it from falling out.

[0021] Preferably, the needle retrieval device 3 includes a first pneumatic gripper 16 and a second pneumatic gripper 17. The first pneumatic gripper 16 is mounted on the rotating arm 19 of the rotary cylinder 18, and the second pneumatic gripper 17 is mounted on the XY-axis slide 20. After the first pneumatic gripper 16 picks up the stainless steel puncture needle core from the lifting plate 4, the rotary cylinder 18 rotates 90 degrees, making the needle tip of the stainless steel puncture needle core vertically upward, so that the second pneumatic gripper 17 can vertically grip it for the next pressing process.

[0022] Preferably, a transfer platform 21 is provided between the first pneumatic gripper 16 and the second pneumatic gripper 17. The end face of the transfer platform 21 is provided with a vertical needle hole 22, and the rotary cylinder 18 is provided with a fourth cylinder 23 to drive its lifting and lowering. When the second pneumatic gripper 17 is still being pressed in the next process, the first pneumatic gripper 16 can first grip the stainless steel puncture needle core from the lifting plate 4, and then rotate 90 degrees through the rotary cylinder 18 so that the needle tip of the stainless steel puncture needle core is vertically upward. Then, through the fourth cylinder 23, the stainless steel puncture needle core is inserted into the needle hole 22 for the second pneumatic gripper 17 to pick up, thereby improving the transfer efficiency.

[0023] The foregoing is not intended to limit the present invention in any way. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed structure and technical content to create equivalent embodiments without departing from the scope of the present invention. However, any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
