[0028] Example 1

[0029] like Figures 1-8 As shown, a vibratory feeder mechanism for injection pen bodies includes a vibratory feeder body 1, a feeding track 2, a guide cylinder 3, a first cutting cylinder 4, a second cutting cylinder 5, a detection fiber optic cable 6, and a material distribution limit seat 7. A spiral feeding track 1-1 is provided inside the vibratory feeder body 1. The outlet end of the vibratory feeder body 1 is connected to the inlet end of the feeding track 2. The feeding track 2 has a straight-line structure. Several injection pen bodies 8 are poured into the vibratory feeder body 1 for vibration, arranged in a row through the feeding track 1-1, and sequentially enter the feeding track 2. A material distribution plate 2-1 is provided on the feeding track 2 along its central axis. The material distribution plate 2-1 is placed on the middle of the injection pen bodies 8 on the feeding track 2. On the feeding track 2, at the end away from the vibratory feeder body 1 (exit end), there is a guide cylinder 3, a first cutting cylinder 4, a second cutting cylinder 5, and a material distribution limit seat 7. The detection fiber optic 6 is set on the material distribution limit seat 7. On the opposite sides of the material distribution limit seat 7, there are material picking positions I 9 and II 10 respectively. The injection pen body 8 from the feeding track 2 first enters the material picking position I 9 under the coordinated action of the first cutting cylinder 4 and the guide cylinder 3, and then enters the material picking position II 10 under the coordinated action of the second cutting cylinder 5 and the guide cylinder 3. The robot arm will grab the injection pen body 8 on the material picking positions I 9 and II 10 and move it to the appropriate position for easy assembly later.

[0030] The first cutting cylinder 4 is equipped with a guide cylinder 3, a second cutting cylinder 5, and a material distribution limit seat 7. The guide cylinder 3, the second cutting cylinder 5, and the first cutting cylinder 4 are arranged sequentially from top to bottom. The guide cylinder 3 reciprocates along a direction parallel to the feeding track 2, the first cutting cylinder 4 reciprocates along a direction perpendicular to the feeding track 2, and the second cutting cylinder 5 reciprocates along a direction perpendicular to the feeding track 2. The material distribution limit seat 7 can move under the coordinated action of the first cutting cylinder 4 and / or the second cutting cylinder 5 and align its picking position (picking position I 9 or picking position II 10) with the outlet end of the feeding track 2, so that the injection pen body 8 from the feeding track 2 can enter the picking position I 9 or the picking position II 10 later.

[0031] In one specific implementation, a mounting base 13 is provided on the top of the first cutting cylinder 4, and a second cutting cylinder 5 is provided on the mounting base 13. A guide seat 14 is provided on the top of the second cutting cylinder 5, and a guide cylinder 3 and a material distribution limit seat 7 are provided on the guide seat 14. The material distribution limit seat 7 is provided on the guide seat 14 near the outlet end of the feeding track 2. An alignment seat 3-1 is provided on the guide cylinder 3.

The feeding track 2 is partially set inside the protective frame 11. The feeding track 2 is fixed to the working platform 15 through the trapezoidal mounting seat 17. The first cutting cylinder 4 reciprocates along a direction perpendicular to the feeding track 2, driving the guide cylinder 3, alignment seat 3-1, second cutting cylinder 5, and material distribution limit seat 7 to move synchronously along the direction perpendicular to the feeding track 2. This aligns the end of the feeding track 2 away from the vibrating plate body 1 (the outlet end) with the material picking position I9. At this time, the material distribution plate 2-1 aligns with the material picking and distribution plate 9-1 at the material picking position I9, allowing one injection pen body 8 on the feeding track 2 to enter the material picking position. Ⅰ9, the second cutting cylinder 5 reciprocates along the direction perpendicular to the feeding track 2 and drives the guide cylinder 3, the alignment seat 31 and the material distribution limit seat 7 on it to move synchronously along the direction perpendicular to the feeding track 2, thereby aligning the end of the feeding track 2 away from the vibrating plate body 1 (the outlet end) with the material picking position Ⅱ10. At this time, the material distribution plate 2-1 is aligned with the material picking and distribution plate 10-1 at the material picking position Ⅱ10, thereby enabling an injection pen body 8 on the feeding track 2 to enter the material picking position Ⅱ10.

[0032] A detection fiber optic cable 6 is installed on the side of the material picking position II10 away from the material picking position I9. When the material picking position I9 or the material picking position II10 is aligned with the outlet end of the feeding track 2, the material picking and distributing plates I9-1 and II10-1 on the guide cylinder 3 are coaxially arranged with the distributing plates on the feeding track. The injection pen body 8 from the feeding track 2 first enters the material picking position I9 under the coordinated action of the first cutting cylinder 4 and the guide cylinder 3, and then enters the material picking position II10 under the coordinated action of the second cutting cylinder 5 and the guide cylinder 3. The robot arm will grab the injection pen body 8 on the material picking position I9 and the material picking position II10.

[0033] A method for using a vibratory feeder mechanism for an injection pen body includes the following steps:

[0034] 1) Pour the injection pen body 8 to be produced into the vibratory feeder body 1. Under the vibration of the vibratory feeder body 1, the injection pen body 8 is neatly arranged through the feeding track 1-1 and enters the feeding track 2.

[0035] 2) The first cutting cylinder 4 moves to the moving point position, the guide cylinder 3 moves to the moving point position, the injection pen body 8 from the feeding track 2 enters the picking position I9 on the material distribution limit seat 7, and after the detection fiber optic 6 senses the product, the first cutting cylinder 4 and the guide cylinder 3 return to the origin.

[0036] 3) The second cutting cylinder 5 moves to the moving point position, the guide cylinder 3 moves to the moving point position, the injection pen body 8 from the feeding track 2 enters the picking position II10 on the material distribution limit seat 7, and after the detection fiber optic 6 senses the product, the second cutting cylinder 5 and the guide cylinder 3 return to the origin.

[0037] The entire process lasts less than 6 seconds.
