DETAILED DESCRIPTION

[0029] The following is combined with Figure 1 To Attachment Figure 6 The principles and features of the present invention are described, and the examples given are only used to explain the present invention, rather than to limit the scope of the present invention.

[0030] As shown in the attached drawings, one end of the safety seat 500 of the blood collection needle is a head with a latch 510, and the other end is a tail with a latch slot 520. The safety seat 500 can be folded in half from its middle part. After the blood collection needle is clamped inside it, the latch 510 is buckled in the latch slot 520, thereby clamping the blood collection needle. The technical solution of the present invention is a feeding device for the blood collection needle safety seat, including a feeding hopper (not shown in the figure) and a material channel platform 100, a material receiving mechanism 200, a rotating mechanism 300 and a flipping mechanism 400 arranged in sequence. The material channel platform 100 is arranged at the discharge port of the feeding hopper, and the safety seat 500 passes through the material channel platform 100, the material receiving mechanism 200, the rotating mechanism 300 in sequence, and is finally fed to the next station through the flipping mechanism 400.

[0031] The channel platform 100 includes a plurality of feeding channels 110 and a direct vibration 120 that can vibrate the channel platform 100. The direct vibration 120 can be arranged below the channel platform 100. In one embodiment, the feeding channels 110 are provided with 2 or 3 rows. A boss 111 is provided inside the feeding channel 110, and the boss 111 extends along the direction of the feeding channel 110, so that the latch 510 at the end of the safety seat 500 is just hung on the boss 111, so that the safety seat 500 is evenly arranged in sequence in the feeding channel 110.

[0032] The material receiving mechanism 200 includes a first clamp 210 and a first driving unit 220. The first clamp 210 can clamp the middle part of the safety seat 500 from the end of the feeding channel 110. There are a plurality of first clamps 210, which are evenly arranged in a straight line and arranged corresponding to the position of the feeding channel 110. In one embodiment, the number of first clamps 210 is an integer multiple of the number of the feeding channel 110. The first driving unit 220 includes a first slide rail 221, a first cylinder 222 and a first material receiving plate 223. The first clamp 210 is connected to the first material receiving plate 223. The first cylinder 222 can drive the first material receiving plate 223 to slide along the first slide rail 221. The forward direction of the material is defined as the feeding direction. The first slide rail 221 is parallel to the feeding direction, that is, the first cylinder 222 can drive the first material receiving plate 223 to reciprocate along the feeding direction on the first slide rail 221. After the first clamping jaw 210 completes the material picking, it is driven by the first driving unit 220 to move along the material loading direction and hand over the safety seat 500 to the rotating mechanism 300 .

[0033] In one embodiment, the material receiving mechanism 200 further includes a second driving unit 230, which is disposed between the first clamping jaw 210 and the first driving unit 220. Specifically, the second driving unit 230 is disposed between the first clamping jaw 210 and the first material receiving plate 223. The second driving unit 230 includes a second slide rail 231, a second cylinder 232, and a second material receiving plate 233. The first clamping jaw 210 is disposed on the second material receiving plate 233. The second cylinder 232 can drive the second material receiving plate 233 to slide along the second slide rail 231, and the second slide rail 231 is disposed perpendicular to the first slide rail 221, that is, the sliding directions of the first material receiving plate 223 and the second material receiving plate 233 are perpendicular. The direction perpendicular to the material loading direction is defined as the material discharging direction, and the second cylinder 232 drives the second material receiving plate 233 to reciprocate along the material discharging direction on the second slide rail 231.

[0034] In one embodiment, the number of the first clamps 210 is twice the number of the feeding channels 110. For ease of description, the first clamps 210 are numbered sequentially from left to right starting from 1. During operation, the odd-numbered first clamps 210 correspond one-to-one with the feeding channels 110 to pick up materials. After picking up materials, the second drive unit 230 drives the first clamps 210 to move along the material discharging direction, so that the even-numbered first clamps 210 correspond one-to-one with the feeding channels 110 to complete the picking up of materials. When the number of the first clamps 210 is multiple times the number of the feeding channels 110, the situation is the same and will not be repeated here. With such a configuration, more materials can be picked up at a time, thereby improving the efficiency of picking up materials.

[0035] The rotating mechanism 300 includes a second clamping jaw 310 and a rotating driving unit 320. The second clamping jaw 310 is provided with a plurality of the same number as the first clamping jaw 210. The second clamping jaw 310 can clamp materials from the first clamping jaw 210. The rotating driving unit 320 can drive the second clamping jaw 310 to rotate along its own axis according to a preset angle. The rotating driving unit 320 includes a rack 321, a plurality of gears 322 meshing with the rack 321, and a rotating driving cylinder 323 driving the rack 321 to reciprocate. The gears 322 are arranged at the end of the second clamping jaw 310 in a one-to-one correspondence. When the rotating driving cylinder 323 drives the rack 321 to move, the gear 322 meshing with the rack 321 rotates and drives the second clamping jaw 310 to rotate along its axis.

[0036] When the safety seat 500 is a special-shaped safety seat, the second clamping jaw 310 cannot directly clamp the material from the first clamping jaw 210. Therefore, in one embodiment, the rotating mechanism 300 further includes a third driving unit 330, which includes a third slide rail 331, a third cylinder 332 and a material removal plate 333. The third slide rail 331 is arranged along the material removal direction. The second clamping jaw 310 is rotatably connected to the material removal plate 333 and can move linearly synchronously with the material removal plate 333. The third cylinder 332 can drive the material removal plate 333 to slide along the third slide rail 331. When the second clamping jaw 310 clamps the material from the first clamping jaw 210, the material can be removed by the third driving unit 330 so as to smoothly remove the material from the first clamping jaw 210.

[0037] The flip mechanism 400 includes a third clamp 410, a flip driving unit 420 and a fourth driving unit 430. The third clamp 410 can clamp materials from the second clamp 310, the flip driving unit 420 includes a flip motor 421, and the flip driving unit 420 can drive the third clamp 410 to rotate along the axis of the output shaft of the flip motor 421; the fourth driving unit 430 is arranged between the third clamp 410 and the flip driving unit 420, and the fourth driving unit 430 includes a fourth slide rail 431, a fourth cylinder 432 and a flip plate 433 arranged at the end of the fourth slide rail 431, and a plurality of third clamps 410 are arranged and are evenly arranged on the flip plate 433 in a straight line, and the telescopic end of the fourth cylinder 432 is connected to the flip plate 433, and can drive the flip plate 433 to move back and forth in a straight line along the fourth slide rail 431. A buffer assembly 440 is also provided on the flip plate 433 . The buffer assembly 440 includes a support leg 441 and a cross bar 442 slidably connected to the support leg 441 . A spring 443 is provided on the outer sleeve of the support leg 441 .

[0038] During operation, the safety pins in the feeding hopper enter the feeding channel 110 in sequence and move forward by means of vibration under the action of the direct vibration 120. When reaching the end of the feeding channel 110, the first clamping jaw 210 approaches the feeding channel 110 under the drive of the first driving unit 220 to clamp the middle part of the safety seat 500, and moves along the material discharging direction under the drive of the second driving unit 230, so that all the first clamping jaws 210 clamp one safety seat 500. Then, the first clamping jaw 210 approaches the second clamping jaw 310 under the drive of the first driving unit 220, and after the second clamping jaw 310 clamps the upper end of the safety seat 500, it rotates 90 degrees under the drive of the rotation driving unit 320. At this time, the third clamp 410, driven by the fourth driving unit 430, approaches the second clamp 310 and clamps the middle part of the safety seat 500, and then flips 180 degrees under the drive of the flip driving unit 420 to feed the safety seat 500 to the next workstation. At the same time, the buffer assembly 440 plays a buffering and protective role when the safety seat 500 is fed to the next workstation.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
