[0025] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.

[0026] This invention discloses a feeding device for irregularly shaped PIN pins, combined with Figures 1 to 7 As shown, it includes a machine platform 1, on which a discharge mechanism 2, a lifting and picking mechanism 3, a feeding mechanism 4, and a pushing mechanism 5 are provided, wherein:

[0027] The lifting and picking mechanism 3 is used to take out multiple PIN pins 100 one by one from the discharge end of the discharge mechanism 2, and arrange the multiple PIN pins 100 vertically at the picking end of the lifting and picking mechanism 3.

[0028] The feeding mechanism 4 includes a plurality of insert holes 400. The feeding mechanism 4 is used to move to the adjacent position of the lifting and picking mechanism 3, and to align the insert holes 400 with the PIN pins 100 of the picking end of the lifting and picking mechanism 3.

[0029] The pushing mechanism 5 is located on the side of the lifting and picking mechanism 3 away from the unloading mechanism 4. The moving end of the pushing mechanism 5 is provided with a plurality of pushing pins 500. The pushing pins 500 are aligned one by one with the PIN pins 100 at the picking end of the lifting and picking mechanism 3. The pushing mechanism 5 is used to drive the plurality of pushing pins 500 to move laterally, thereby pushing the PIN pins 100 and inserting the PIN pins 100 into the insertion hole 400.

[0030] In the above structure, the material feeding mechanism 2, the lifting and picking mechanism 3, the unloading mechanism 4, and the pushing mechanism 5 are all provided on the machine base 1. The material feeding mechanism 2 is used to arrange the incoming PIN pins 100 sequentially. After the lifting and picking mechanism 3 takes out multiple PIN pins 100 one by one from the discharge end of the material feeding mechanism 2, it arranges the multiple PIN pins 100 vertically at the picking end of the lifting and picking mechanism 3. Then, the unloading mechanism 4 moves to the adjacent position of the lifting and picking mechanism 3 and ensures that the insertion hole 400 is aligned with the PIN pins 100 at the picking end of the lifting and picking mechanism 3. During the pushing process, the pushing mechanism 5 drives multiple pushing pins 500 to move laterally. The pushing pins 500 push the PIN pins 100 and insert them into the insertion hole 400. Compared with existing technologies, this invention is not limited by the shape of the PIN pins. It can not only realize the automatic arrangement and vertical picking of irregularly shaped PIN pins, but also take out multiple PIN pins in batches, which can effectively improve the accuracy and efficiency of PIN pin arrangement and feeding.

[0031] As a preferred embodiment, the discharge mechanism 2 includes a vibrating feeding plate 20 and a discharge track 21. One end of the discharge track 21 is connected to the outlet of the vibrating feeding plate 20, and the other end of the discharge track 21 extends to the adjacent location of the lifting and unloading mechanism 3.

[0032] Combination Figures 2 to 5As shown, in this embodiment, the lifting and picking mechanism 3 includes a lifting mechanism 30. The moving end of the lifting mechanism 30 is provided with a lifting support 31. A picking end plate 32 is fixed on the outer side of the lifting support 31. A picking cylinder 33 is fixed between the picking end plate 32 and the lifting support 31. A picking block 34 is fixed on the moving end of the picking cylinder 33. The picking block 34 is driven by the picking cylinder 33 to move closer to or away from the picking end plate 32. A plurality of vertically distributed PIN needle receiving slots 320 are opened on the picking end plate 32. A plurality of PIN needle suction heads 340 for picking up the PIN needles 100 are formed on the picking block 34. The PIN needle suction heads 340 are aligned with the PIN needle receiving slots 320 one by one, and the PIN needle suction heads 340 can be inserted into the PIN needle receiving slots 320.

[0033] In specific operation, taking the batch retrieval of 6 PIN pins 100 as an example, the lifting mechanism 30 drives the lifting support 31 to move up and down so that the lowest of the 6 PIN pin receiving slots 320 is aligned with the outlet of the discharge track 21. The PIN pin 100 at the front end of the discharge track 21 enters the PIN pin receiving slot 320 under the action of the incoming material thrust and is adsorbed onto the PIN pin suction head 340. Then, the lifting mechanism 30 drives the lifting support 31 to rise one step, so that the second PIN pin receiving slot 320 at the lower end is aligned with the outlet of the discharge track 21, thereby loading the next PIN pin 100 into the second PIN pin receiving slot 320. This process continues until all 6 PIN pin receiving slots 320 are filled with PIN pins 100, thus completing the batch retrieval and vertical equidistant arrangement of 6 PIN pins 100.

[0034] In order to support and fix the material picking end plate 32, in this embodiment, two support plates 310 are fixed on the lifting support 31, and the material picking end plate 32 is fixed to the ends of the two support plates 310.

[0035] Combination Figure 4 and Figure 5 As shown, in order to enable the PIN needle suction head 340 to adsorb PIN needles 100, in this embodiment, the PIN needle suction head 340 is provided with a plurality of negative pressure suction holes 341, and the material taking block 34 is provided with a plurality of negative pressure air chambers 342 on the side opposite to the PIN needle suction head 340. The negative pressure suction holes 341 are connected to the negative pressure air chambers 342. The material taking block 34 and the moving end of the material taking cylinder 33 are connected by a cover plate 35, and the cover plate 35 covers the outside of the negative pressure air chambers 342.

[0036] In the above structure, the PIN needle suction head 340 is a strip-shaped protrusion that matches the shape of the PIN needle 100. Multiple negative pressure suction holes 341 are arranged sequentially on the PIN needle suction head 340 to ensure balanced suction force on the PIN needle 100. Simultaneously, the shape of the PIN needle suction head 340 matches the shape of the PIN needle receiving slot 320, allowing the PIN needle suction head 340 to enter and exit the PIN needle receiving slot 320. Furthermore, the material picking block 34 has multiple negative pressure air chambers 342 on its back side, and multiple negative pressure interfaces 343 connected to the negative pressure air chambers 342 on its side. By setting multiple negative pressure air chambers 342 and negative pressure interfaces 343, each PIN needle suction head 340 can stably pick up the PIN needle 100 and ensure balanced suction force.

[0037] In a preferred embodiment, the picking end plate 32 has a notch 321 on the side facing the picking block 34, and the picking block 34 is inserted into the notch 321 with the two slidingly engaged. This insertion relationship between the picking end plate 32 and the notch 321 ensures accurate alignment between the PIN needle suction head 340 and the PIN needle receiving slot 320, preventing misalignment.

[0038] Combination Figure 3 and Figure 6 As shown, to achieve batch feeding, in this embodiment, the feeding mechanism 5 includes a vertical support plate 50, a feeding cylinder 51 fixed on the vertical support plate 50, a feeding motion block 52 fixed at the moving end of the feeding cylinder 51, and multiple feeding needles 500 disposed on the feeding motion block 52. A guide plate 53 is fixed at the end of the vertical support plate 50, and a stepped portion 530 is formed at one end of the guide plate 53 near the picking end plate 32. Multiple guide grooves 531 are provided on the stepped portion 530 to accommodate the feeding needles 500 and the PIN needles 100. The guide grooves 531 are aligned one-to-one with the PIN needle receiving slots 320. When the picking cylinder 33 drives the picking block 34 to approach the picking end plate 32, the PIN needle suction head 340 pushes the PIN needles 100 out of the PIN needle receiving slots 320 and places them in the guide grooves 531.

[0039] In the above structure, when the picking cylinder 33 moves outward, the PIN needle suction head 340 pushes the PIN needle 100 out of the PIN needle receiving slot 320. Because the guide groove 531 is aligned with the PIN needle receiving slot 320, the PIN needle 100 enters the guide groove 531. Since the guide groove 531 also accommodates the pusher needle 500, the pusher needle 500 and the PIN needle 100 are in a one-to-one alignment relationship at this time. Figure 3As shown, when the six insertion holes 400 on the feeding mechanism 4 are aligned with the six pins 100, the pushing cylinder 51 drives the pushing motion block 52 to move laterally, and the six pushing pins 500 push the six pins 100 into the six insertion holes 400 in the same way, thereby realizing the functions of batch feeding and insertion.

[0040] Please see Figure 1 and Figure 7 In this embodiment, the feeding mechanism 4 includes a transverse motion mechanism 40. The moving end of the transverse motion mechanism 40 is provided with a transverse motion support plate 41. A rotary motion mechanism 42 is fixed on the transverse motion support plate 41. A feeding block 43 is provided at the eccentric position of the rotating shaft of the rotary motion mechanism 42. The insertion hole 400 is provided on the feeding block 43.

[0041] The rotary motion mechanism 42 is preferably a rotary cylinder, and the lateral motion mechanism 40 drives the rotary motion mechanism 42 to move until the unloading block 43 is transported to the adjacent position of the picking end plate 32. Afterwards, the rotary motion mechanism 42 drives the unloading block 43 to rotate so that the six insertion holes 400 are aligned with the six PIN pins 100. In this embodiment, the unloading block 43 is preferably located off-center from the axis of the rotary motion mechanism 42 to avoid positional interference between the unloading block 43 and components such as the lifting mechanism 30 during translation. Specifically, when the feeding mechanism 4 needs to pick up materials, the rotary motion mechanism 42 first flips the feeding block 43 to a side position, that is, the insertion hole 400 is placed to the side. Then the transverse motion mechanism 40 moves until the insertion hole 400 is aligned with the PIN pin 100. After the pushing mechanism 5 pushes the material and the PIN pin 100 is inserted into the insertion hole 400, the rotary motion mechanism 42 flips the feeding block 43 to an upward position. At this time, all the PIN pins 100 are facing upward. When the transverse motion mechanism 40 moves in a straight line, it can prevent the PIN pins 100 from touching the lifting mechanism 30 and other components. After the transverse motion mechanism 40 moves to the next station, the feeding block 43 can be flipped to a side position again for the subsequent structure to pick up the PIN pins 100 in batches.

[0042] Based on this, the present invention also relates to a method for feeding irregularly shaped PIN pins. In this embodiment, the PIN pin 100 is a "Z"-shaped PIN pin. The method is implemented based on a device, which includes a machine platform 1. The machine platform 1 is equipped with a discharge mechanism 2, a lifting and picking mechanism 3, a feeding mechanism 4, and a pushing mechanism 5. The feeding mechanism 4 includes multiple insertion holes 400. The pushing mechanism 5 is located on the side of the lifting and picking mechanism 3 away from the feeding mechanism 4. The moving end of the pushing mechanism 5 is provided with multiple pushing pins 500. The pushing pins 500 are aligned one-to-one with the PIN pins 100 at the picking end of the lifting and picking mechanism 3. The method includes the following steps:

[0043] Step S1: The lifting and picking mechanism 3 takes out multiple PIN pins 100 one by one from the discharge end of the discharge mechanism 2, and arranges the multiple PIN pins 100 vertically at the picking end of the lifting and picking mechanism 3.

[0044] In step S2, the feeding mechanism 4 moves to the adjacent position of the lifting and picking mechanism 3, and aligns the insertion hole 400 with the PIN pin 100 of the picking end of the lifting and picking mechanism 3.

[0045] In step S3, the pushing mechanism 5 is used to drive multiple pushing pins 500 to move laterally, thereby pushing the PIN pin 100 and inserting the PIN pin 100 into the insertion hole 400.

[0046] In this embodiment, during operation, the lifting mechanism 30 drives the lifting support 31 to gradually rise, so that the lowest of the six PIN needle receiving slots 320 aligns with the outlet of the discharge track 21. The PIN needle 100 at the foremost end of the discharge track 21 enters the PIN needle receiving slot 320 under the pushing force of the incoming material and is adsorbed onto the PIN needle suction head 340. Then, the lifting mechanism 30 drives the lifting support 31 to rise one step, so that the second PIN needle receiving slot 320 at the lower end aligns with the outlet of the discharge track 21. Then, the next PIN needle 100 is loaded into the second PIN needle receiving slot 320, and so on, until all six PIN needle receiving slots 320 are filled with PIN needles 100, thereby completing the batch picking and vertical equal spacing arrangement of the six PIN needles 100. Subsequently, the lifting mechanism 30 continues to rise, aligning the six PIN pin receiving slots 320 with the six guide slots 531 on the guide plate 53, as shown. Figure 3As shown, the material-picking cylinder 33 is controlled to move outward, and the PIN needle suction head 340 pushes the PIN needle 100 out of the PIN needle receiving slot 320, so that the six PIN needles 100 enter the six guide slots 531 respectively. At this time, the pusher needle 500 and the PIN needle 100 are in a one-to-one alignment relationship. At the same time, the feeding mechanism 4 moves to the PIN needle picking position, that is, the six insertion holes 400 on the feeding mechanism 4 are aligned with the six PIN needles 100. The pusher cylinder 51 drives the pusher moving block 52 to move laterally, and the six pusher needles 500 push the six PIN needles 100 into the six insertion holes 400 in the same way, thereby realizing the function of batch feeding and insertion. Then, the unloading block 43 of the rotary motion mechanism 42 is flipped to the upward position, at which time all the PIN pins 100 are facing upward. When the lateral motion mechanism 40 moves in a straight line, it can prevent the PIN pins 100 from touching the lifting mechanism 30 and other components. After the lateral motion mechanism 40 moves to the next station, the unloading block 43 can be flipped to the side position for the subsequent structure to take the PIN pins 100 in batches.

[0047] Based on the above principles, it can be seen that the present invention is not limited by the shape of the PIN pins. It can not only realize the automatic arrangement and vertical picking of irregularly shaped PIN pins, but also take out multiple PIN pins in batches, which can effectively improve the accuracy and efficiency of PIN pin arrangement and feeding.

[0048] 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 or improvements made within the technical scope of the present invention should be included within the scope of protection of the present invention.
