DETAILED DESCRIPTION

[0030] The following is combined with Figure 1 To Attachment Figure 8 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.

[0031] A safety needle sliding sleeve feeding device, such as Figure 1 — Figure 4 As shown, it includes: a feeding component 1, a dividing component 5 and a grabbing component 6, the feeding component 1 is provided with a linear vibrator 2, the upper part of the linear vibrator 2 is provided with a first slide rail 3 that matches the slot 402 of the safety needle slide sleeve 4, the bottom of the linear vibrator 2 is provided with a support seat 11, and the first slide rail 3 is inclined from high to low; in this embodiment, in order to achieve long-distance transportation, the number of linear vibrators 2 is two groups, and the first slide rails 3 of the two groups of linear vibrators 2 are connected end to end at the same inclination angle, and the safety needle slide sleeves 4 from the vibration disk enter the first slide rail 3 one by one in sequence and move along the first slide rail 3. The device is provided with a first sensor 12 for detecting the safety needle slide sleeve 4 at the feeding end of the first group of first slide rails 3. In this embodiment, the first sensor 12 is a proximity switch, and a photoelectric switch familiar to those skilled in the art can also be selected.

[0032] like Figure 5 — Figure 6As shown, the safety needle slide sleeve 4 from the feeding assembly 1 enters the dividing assembly 5, and the dividing assembly 5 includes a sorting spiral belt 7 and a sorting track 8. The side of the sorting track 8 is close to the sorting spiral belt 7, and the feeding part of the sorting track 8 is connected to the end of the last group of first slide rails 3. The sorting track 8 includes a feeding section 801, a sorting section 802 and a discharging section 803. The feeding section 801 is inclined from low to high. At this stage, the front safety needle slide 4 is pushed by the subsequent safety needle slide 4, and the safety needle slide 4 climbs at a slower speed into the horizontal sorting section 802. In the sorting section 802, the safety needle slide 4 is acted upon by the sorting spiral belt 7, and the originally closely adjacent safety needle slides 4 are evenly spaced to facilitate subsequent grabbing. After grabbing, the remaining safety needle slide 4 enters the discharging section 803, which is inclined from high to low. After entering, the safety needle slide 4 slides freely under the action of gravity and falls into the tail of the sorting track 8, where a receiving box 29 is provided. The feeding section 801 is provided with a hanging pressing plate 19 for guiding, and the safety needle slide 4 can be introduced into the feeding section 801 in sequence. The sorting section 802 is provided with a second sensor 20 at the connection with the feeding section 801 for identifying the safety needle slide 4. The sorting spiral belt 7 is provided with a conveying shaft 14 driven by a motor 13, and a spirally wound groove 15 is provided on the conveying shaft 14. The groove width of the spirally wound groove 15 is adapted to the first body 401 of the safety needle slide 4. The sorting spiral belt 7 is also provided with a detection piece 16 that rotates synchronously with the conveying shaft 14. The detection piece 16 is in a disc shape and has a notch 17 in the circumferential direction. A third sensor 18 is provided near the detection piece 16. In this embodiment, in order to facilitate accurate control of the rotation speed and start and stop of the conveying shaft 14, the motor 13 uses a servo motor; the third sensor 18 is a photoelectric switch, or a proximity switch well known to those skilled in the art. The motor 13 drives the conveying shaft 14 to rotate, and the third sensor 18 senses the detection piece 16 until the notch 17 rotates to the third sensor 18, and the sensing signal is cut off. At this time, the conveying shaft 14 stops rotating and the safety needle slide 4 is grabbed. After grabbing, the remaining safety needle slide 4 falls into the tail of the sorting track 8 and a receiving box 29 is provided.

[0033] like Figure 7 — Figure 8As shown, the material grabbing assembly 6 includes a frame seat 9 and a grabbing mechanism 10 located on the upper part of the frame seat 9 for grabbing the safety needle slide sleeve 4. The grabbing mechanism 10 is provided with a grabbing portion 22 driven by a first cylinder 21, and the grabbing portion 22 can achieve vertical displacement under the action of the first cylinder 21. The grabbing mechanism 10 is connected to the top of the frame seat 9 through a second slide rail 23, and the side of the grabbing mechanism 10 is connected to a second cylinder 24 so that it can reciprocate along the second slide rail 23. The grabbing portion 22 includes a plurality of spaced apart insertion pins 25, a pressure plate 26 and a straightening plate 27. The insertion pin 25 is located above the first body portion 401. When the first cylinder 21 drives the grabbing portion 22 to move downward to grab the safety needle sleeve 4, the insertion pin 25 can be inserted into the inner hole of the first body portion 401, and the pressure plate 26 abuts against the top end of the safety needle sleeve 4. The straightening plate 27 is provided with a plurality of spaced apart limiting grooves 28 for accommodating the second body portion 403 of the safety needle sleeve 4. The combined action of the pressure plate 26 and the limiting groove 28 can prevent the safety needle sleeve 4 from being displaced during the grabbing process. In order to facilitate the insertion pin 25 to enter the hole of the first body portion 401, the lower end of the insertion pin 25 is tapered.

[0034] Working principle of the present invention: the safety needle sleeve 4 from the upstream vibration plate is arranged in sequence through the feeding section 801 of the sorting track 8 and enters the sorting section 802 through the action of the feeding assembly 1. In the sorting section 802, it is evenly spaced by the action of the spirally wound groove 15. When the third sensor 18 senses the position of the notch 17 of the detection sheet 16, the conveying shaft 14 stops rotating. When the first cylinder 21 drives the grasping part 22 to move down to grasp the safety needle sleeve 4, the pin 25 can be inserted into the inner hole of the first body 401 to complete the grasping, and under the action of the second cylinder 24, the transfer of the safety needle sleeve 4 is completed, thereby realizing the automatic loading of the safety needle sleeve 4. The entire loading process does not require manual intervention, saving labor costs and improving loading efficiency.

[0035] 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.
