[0026] The lifting and taking mechanism 3 is used to take out a plurality of PIN needles 100 one by one from the discharging end of the discharging mechanism 2, and vertically arrange the plurality of PIN needles 100 at the taking end of the lifting and taking mechanism 3;

[0027] The material unloading mechanism 4 includes a plurality of material insertion holes 400, and the material unloading mechanism 4 is used to move to the adjacent position of the lifting and retrieving mechanism 3, and align the material insertion holes 400 with the PIN pins 100 at the retrieving end of the lifting and retrieving mechanism 3 one by one;

[0028] The pushing mechanism 5 is located on a side of the lifting and picking mechanism 3 away from the unloading mechanism 4. A plurality of pushing needles 500 are provided at the moving end of the pushing mechanism 5. The pushing needles 500 are aligned one by one with the PIN needles 100 at the picking end of the lifting and picking mechanism 3. The pushing mechanism 5 is used to drive the plurality of pushing needles 500 to move laterally, and the PIN needle 100 is pushed by the pushing needle 500, thereby inserting the PIN needle 100 into the insertion hole 400.

[0029] In the above structure, the discharging mechanism 2, the lifting and picking mechanism 3, the unloading mechanism 4 and the pushing mechanism 5 are simultaneously arranged on the machine 1. The discharging mechanism 2 is used to arrange the incoming materials of the PIN needles 100 in sequence. After the lifting and picking mechanism 3 takes out multiple PIN needles 100 one by one from the discharging end of the discharging mechanism 2, the multiple PIN needles 100 are vertically arranged 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 holes 400 are aligned one by one with the PIN needles 100 at the picking end of the lifting and picking mechanism 3. When pushing the material, the pushing mechanism 5 drives the multiple pushing needles 500 to move horizontally, and the pushing needles 500 push the PIN needles 100, and then the PIN needles 100 are inserted into the insertion holes 400. Compared with the prior art, the utility model is not limited by the shape of PIN needles. It can not only realize the automatic arrangement and vertical material removal of special-shaped PIN needles, but also can take out multiple PIN needles in batches, which can effectively improve the accuracy and work efficiency of PIN needle arrangement and feeding.

[0030] As a preferred embodiment, the discharge mechanism 2 includes a vibrating loading tray 20 and a discharge track 21, one end of the discharge track 21 is connected to the outlet of the vibrating loading tray 20, and the other end of the discharge track 21 extends to the adjacent position of the lifting and picking mechanism 3.

[0031] Combination Figures 2 to 5 As shown, in the embodiment, the lifting and feeding mechanism 3 includes a lifting mechanism 30, and the moving end of the lifting mechanism 30 is provided with a lifting support 31, and a feeding end plate 32 is fixed to the outer side of the lifting support 31, and a feeding cylinder 33 is fixed between the feeding end plate 32 and the lifting support 31, and a feeding block 34 is fixed to the moving end of the feeding cylinder 33, and the feeding cylinder 33 drives the feeding block 34 to approach or move away from the feeding end plate 32, and a plurality of vertically distributed PIN needle accommodating slots 320 are provided on the feeding end plate 32, and a plurality of PIN needle suction heads 340 for sucking the PIN needles 100 are formed on the feeding block 34, and the PIN needle suction heads 340 are aligned one by one with the PIN needle accommodating slots 320, and the PIN needle suction heads 340 can be inserted into the PIN needle accommodating slots 320.

[0032] During specific operation, taking the batch taking of 6 PIN needles 100 each time as an example, the lifting mechanism 30 drives the lifting support 31 to move up and down, so that the lowest one of the 6 PIN needle accommodating slots 320 is aligned with the outlet of the discharge track 21, and the PIN needle 100 at the front end of the discharge track 21 enters the PIN needle accommodating slot 320 under the thrust of the incoming material, and is adsorbed on the PIN needle suction head 340. After that, the lifting mechanism 30 drives the lifting support 31 to rise one step, so that the second PIN needle accommodating slot 320 at the lower end is aligned with the outlet of the discharge track 21, so that the next PIN needle 100 is loaded into the second PIN needle accommodating slot 320, and so on, until all the 6 PIN needle accommodating slots 320 are loaded with PIN needles 100, thereby completing the batch taking and vertical equidistant arrangement of 6 PIN needles 100.

[0033] In order to support and fix the material taking end plate 32 , in the present embodiment, two support plates 310 are fixed on the lifting support 31 , and the material taking end plate 32 is fixed to the ends of the two support plates 310 .

[0034] Combination Figure 4 and Figure 5 As shown, in order to enable the PIN needle suction head 340 to have the ability to absorb the PIN needle 100, in the present embodiment, a plurality of negative pressure suction holes 341 are provided on the PIN needle suction head 340, and a plurality of negative pressure air cavities 342 are provided on the side of the material taking block 34 facing away from the PIN needle suction head 340, and the negative pressure suction holes 341 are communicated with the negative pressure air cavities 342, and the material taking block 34 and the moving end of the material taking cylinder 33 are connected via a cover plate 35, and the cover plate 35 covers the outer side of the negative pressure air cavity 342.

[0035] In the above structure, the PIN needle suction head 340 is a bar-shaped convex block that matches the shape of the PIN needle 100, and a plurality of negative pressure suction holes 341 are arranged in sequence on the PIN needle suction head 340 to ensure that the suction force on the PIN needle 100 is balanced. At the same time, the PIN needle suction head 340 matches the shape of the PIN needle receiving slot 320, so that the PIN needle suction head 340 can enter and exit the PIN needle receiving slot 320. On this basis, the back of the material taking block 34 has a plurality of negative pressure air cavities 342, and the side of the material taking block 34 is also provided with a plurality of negative pressure interfaces 343 connected to the negative pressure air cavities 342. By providing a plurality of negative pressure air cavities 342 and negative pressure interfaces 343, each PIN needle suction head 340 can stably absorb the PIN needle 100 and ensure balanced suction force.

[0036] As a preferred embodiment, a notch 321 is provided on one side of the material taking end plate 32 facing the material taking block 34, and the material taking block 34 is inserted into the notch 321 and the two are slidably matched. Based on the plug-in relationship between the material taking end plate 32 and the notch 321, the PIN needle suction head 340 can be accurately aligned with the PIN needle receiving slot 320 to avoid misalignment.

[0037] Combination Figure 3 and Figure 6 As shown, in order to realize batch pushing, in the present embodiment, the pushing mechanism 5 includes a vertical support plate 50, on which a pushing cylinder 51 is fixed, and a pushing moving block 52 is fixed at the moving end of the pushing cylinder 51, and a plurality of pushing needles 500 are arranged on the pushing moving block 52, and a guide plate 53 is fixed at the end of the vertical support plate 50, and a step portion 530 is formed at one end of the guide plate 53 close to the material picking end plate 32, and a plurality of guide grooves 531 for accommodating the pushing needles 500 and the PIN needles 100 are formed on the step portion 530, and the guide grooves 531 are aligned one by one with the PIN needle accommodating slots 320, and when the material picking cylinder 33 drives the material picking block 34 to approach the material picking end plate 32, the PIN needle suction head 340 pushes the PIN needle 100 out of the PIN needle accommodating slot 320 and places it in the guide groove 531.

[0038] In the above structure, when the material taking cylinder 33 moves outward, the PIN needle suction head 340 pushes the PIN needle 100 out of the PIN needle accommodating slot 320. Since the guide slot 531 is aligned one-to-one with the PIN needle accommodating slot 320, the PIN needle 100 enters the guide slot 531. Since the guide slot 531 accommodates the push needle 500 at the same time, the push needle 500 and the PIN needle 100 are in a one-to-one aligned position relationship at this time, as shown in FIG. Figure 3 As shown, when the six insertion holes 400 on the unloading mechanism 4 are aligned with the six PIN needles 100, the pushing cylinder 51 drives the pushing motion block 52 to move horizontally, and the six pushing needles 500 push the six PIN needles 100 into the six insertion holes 400 together with the cloth, thereby realizing the functions of batch feeding and insertion.

[0039] See also Figure 1 and Figure 7 In this embodiment, the unloading mechanism 4 includes a transverse motion mechanism 40, and a transverse motion support plate 41 is provided at the moving end of the transverse motion mechanism 40. A rotary motion mechanism 42 is fixed on the transverse motion support plate 41. A unloading block 43 is provided at the eccentric position of the rotating shaft of the rotary motion mechanism 42, and the insertion hole 400 is provided on the unloading block 43.

[0040] The rotary motion mechanism 42 is preferably a rotary cylinder, and the transverse motion mechanism 40 is used to drive the rotary motion mechanism 42 to move until the material removal block 43 is transported to the adjacent position of the material taking end plate 32, and then the rotary motion mechanism 42 drives the material removal block 43 to flip so that the six material insertion holes 400 are aligned with the six PIN needles 100. In this embodiment, the material removal block 43 is preferably arranged at an eccentric position of the rotating shaft of the rotary motion mechanism 42, the purpose of which is to avoid position interference between the material removal block 43 and components such as the lifting mechanism 30 during the translation process. Specifically, when the material removal mechanism 4 needs to take material, the rotary motion mechanism 42 first flips the material removal block 43 to a lateral position, that is, the insertion hole 400 is placed sideways, and then the transverse motion mechanism 40 moves until the insertion hole 400 is aligned with the PIN needle 100. After the pushing mechanism 5 pushes the material and the PIN needle 100 is inserted into the insertion hole 400, the material removal block 43 of the rotary motion mechanism 42 is flipped to an upward position. At this time, the PIN needles 100 are all facing upward. When the transverse motion mechanism 40 moves in a straight line, the PIN needles 100 can be prevented from touching the lifting mechanism 30 and other components. After the transverse motion mechanism 40 moves to the next workstation, the material removal block 43 can be flipped to a lateral position again to allow subsequent structures to batch take the PIN needles 100.

[0041] On this basis, the utility model also relates to a method for arranging and feeding special-shaped PIN needles. The PIN needle 100 in this embodiment is a "Z"-shaped PIN needle. The method is implemented based on a device. The device includes a machine table 1, and the machine table 1 is provided 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 a plurality of 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 a plurality of pushing needles 500. The pushing needles 500 are aligned one by one with the PIN needles 100 at the feeding end of the lifting and picking mechanism 3. The method includes the following steps:

[0042] Step S1, the lifting and taking mechanism 3 takes out a plurality of PIN needles 100 one by one from the discharging end of the discharging mechanism 2, and vertically arranges the plurality of PIN needles 100 at the taking end of the lifting and taking mechanism 3;

[0043] Step S2, the material unloading mechanism 4 moves to the adjacent position of the lifting and picking mechanism 3, and aligns the material insertion holes 400 with the PIN pins 100 at the picking end of the lifting and picking mechanism 3 one by one;

[0044] In step S3 , the pushing mechanism 5 is used to drive the plurality of pushing pins 500 to move horizontally, and the pushing pins 500 push the PIN pins 100 , thereby inserting the PIN pins 100 into the inserting holes 400 .

[0045] When the present embodiment is in operation, the lifting mechanism 30 drives the lifting support 31 to gradually rise so that the lowest one of the six PIN needle accommodating slots 320 is aligned with the outlet of the discharge track 21, and the frontmost PIN needle 100 in the discharge track 21 enters the PIN needle accommodating slot 320 under the thrust of the incoming material and is adsorbed on the PIN needle suction head 340. Afterwards, the lifting mechanism 30 drives the lifting support 31 to rise one step so that the second PIN needle accommodating slot 320 at the lower end is aligned with the outlet of the discharge track 21, and then the next PIN needle 100 is loaded into the second PIN needle accommodating slot 320, and so on, until all the six PIN needle accommodating slots 320 are loaded with PIN needles 100, thereby completing the batch material removal and vertical equidistant arrangement of the six PIN needles 100. Afterwards, the lifting mechanism 30 continues to rise, so that the six PIN receiving slots 320 are aligned one by one with the six guide slots 531 on the guide plate 53, as shown in FIG. Figure 3 As shown, the material taking cylinder 33 is controlled to move outward, and the PIN needle suction head 340 is used to push the PIN needle 100 out of the PIN needle accommodating slot 320, so that the six PIN needles 100 enter the six guide slots 531 accordingly. At this time, the pushing needle 500 and the PIN needle 100 are in a one-to-one aligned position relationship. At the same time, the unloading mechanism 4 moves to the position of taking the PIN needle, that is, the six insertion holes 400 on the unloading mechanism 4 are aligned with the six PIN needles 100. The pushing cylinder 51 drives the pushing motion block 52 to move horizontally, and the six pushing needles 500 push the six PIN needles 100 into the six insertion holes 400 at the same time, thereby realizing the functions of batch feeding and insertion. Then, the blanking block 43 of the rotating motion mechanism 42 is flipped to an upward position. At this time, the PIN needles 100 are all facing upward. When the transverse motion mechanism 40 moves in a straight line, the PIN needles 100 can be prevented from touching the lifting mechanism 30 and other components. After the transverse motion mechanism 40 moves to the next workstation, the blanking block 43 can be flipped to a lateral position to allow subsequent structures to batch use the PIN needles 100.

[0046] Based on the above principle, it can be seen that the utility model is not limited by the shape of the PIN needles. It can not only realize the automatic arrangement and vertical material removal of special-shaped PIN needles, but also can take out multiple PIN needles in batches, which can effectively improve the accuracy and work efficiency of PIN needle arrangement and feeding.

[0047] 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 in the scope of protection of the present invention.
