[0027] The material that is in the feed box 31 is fixed on the loading platform 314, and the loading platform 316 is fixed on the loading platform 314.

[0028] In this embodiment, the feed plate 31 is provided with edges on both sides along the feeding direction, and the lower end of the feed plate 31 extends into the material box 2; a hollow material guide column 33 for the pin shaft to pass through is vertically arranged on the feed plate 31, and the two ends of the material guide column 33 are respectively connected to the discharge hole 312 and the output module 4.

[0029] refer to Figure 2 The feeding plates 31 can be 2, 3 or more, arranged side by side, with their lower ends extending into the material box 2. This embodiment does not limit this. The number of the feeding plates 31 is determined according to specific production requirements. In this embodiment, there are 2 feeding plates 31 arranged side by side.

[0030] In this embodiment, the material guiding column 33 is provided with a notch 331 for the pin to pass through.

[0031] Preferably, the feeding plate 31 is provided with a first blocking rod 34 and a second blocking rod 35 which are arranged perpendicular to the feeding trough 311 and can be extended and retracted in the feeding trough 311. The first blocking rod 34 and the second blocking rod 35 are arranged in sequence along the conveying direction of the feeding trough 311. The first feeding rod 32 and the second feeding rod 32 are driven to extend and retract by the first push rod cylinder 36. The first blocking rod 34 and the second blocking rod 35 extend to block the two adjacent pins in the feeding trough 311. The second blocking rod 34 and the second blocking rod 35 extend to block the two adjacent pins in the feeding trough 311. The rod 35 is arranged close to the discharge hole 312. When the pin is discharged, the second stop rod 35 retracts, so that the pin between the first stop rod 34 and the second stop rod 35 is output from the feed trough 311 to the discharge hole 312; after the discharge is completed, the second stop rod 35 extends, and the first stop rod 34 retracts, so that the pin slides to the second stop rod 35, and the first stop rod 34 extends, so that there is only one pin between the first stop rod 34 and the second stop rod 35, so that one pin is output at a time.

[0032] The extension and retraction of the first material blocking rod 34 and the second material blocking rod 35 may also be driven by other driving methods such as an electric cylinder, etc., which is not limited in this embodiment.

[0033] In this embodiment, reference Figure 1 The output module 4 includes a guide plate 41 arranged below the guide column 33, and the guide plate 41 is arranged at an angle; the lower end of the guide plate 41 is provided with a reversing block 42 for reversing the pin shaft output by the guide plate 41; the output end of the reversing block 42 is provided with a hollow guide block 43.

[0034] Specifically, the pin is input into the guide plate 41 through the guide column 33, and then output from the guide plate 41 to the reversing block 42, where the reversing block 42 realizes the reversal of the pin, and finally is output by the guide block 43; the pin output from the guide column 33 is in a state where the end with the largest diameter is facing upward. When it is input into the guide plate 41, since the center of gravity of the pin is at the maximum diameter, it is input into the reversing block 42 with the end with the largest diameter in front under the action of its own weight. After the reversing block 42 reverses, the pin is input into the guide block 43 with the end with the largest diameter facing upward, and is output by the guide block 43.

[0035] In this embodiment, reference Figure 3 A reversing groove 421 is provided in the reversing block 42, and the reversing groove 421 includes an upslope surface a, a downslope surface b arranged relative to the upslope surface a, and a connecting surface c connecting the upslope surface and the downslope surface. The guide block 43 is arranged below the downslope surface b of the reversing groove 421.

[0036] Specifically, the feed plate 31 and the guide plate 41 in this embodiment are arranged at an angle, making full use of the deadweight of the pin to realize the conveyance of the pin, without the need for other conveying force to realize the conveyance of the pin, with a simple structure and saving production costs.

[0037] As a specific implementation of this embodiment, the guide plate 41 is a circular tubular structure from the bottom of the guide column 33 to its output end, and one end of its input pin shaft facing the side of the guide column 33 is an open structure, which can better play a role in guiding materials.

[0038] In this embodiment, reference Figure 4 A conical cavity 431 for guiding the output of the pin is provided in the guide block 43, and a discharge pipe 44 for outputting the pin, which is connected to the conical cavity 431, is provided at the bottom of the guide block 43. The pin is transported to a preset position through the discharge pipe 44, so that the external robot can accurately pick up the material.

[0039] As a specific implementation of the preferred scheme of this embodiment, the bottom of the feeding rod 32 is provided with an electromagnet 37 for grabbing or putting down the pin shaft, and the feeding of the pin shaft is realized by the electromagnet 37. When grabbing the pin, the feeding rod 32 is driven down by the first lifting cylinder 38 set on the frame 1, and the electromagnet 37 is energized to absorb the pin shaft. After sucking the pin shaft, the feeding rod 32 is driven by a second push rod cylinder 39 set on the frame 1 to move horizontally to the upper end of the feeding plate 31. The electromagnet 37 is de-energized, and the pin shaft falls at the upper end of the feeding plate 31 into the feeding trough 311 or slides back into the material box 2. The second push rod cylinder 39 drives the feeding rod 32 to move horizontally to the top of the material box 2, and repeats the above process to realize feeding.

[0040] The lifting and translation of the feeding rod 32 can also be driven by an electric cylinder or a screw rod, which is not limited in this embodiment.

[0041] A sliding plate 11 is provided on the frame 1 , the first lifting cylinder 38 is fixed on the sliding plate 11 , and the power output end of the second push rod cylinder 39 is connected to the sliding plate 11 .

The mounting base 5 is also provided with a liftable loading plate 51, and the loading plate 51 is provided with a loading column 52 facing the discharge pipe 44.

[0044] A second lifting cylinder 53 is provided on the mounting seat 5, and the loading plate 51 is fixedly connected to the power output end of the second lifting cylinder 53. When the pin shaft has an automatic feeding mechanism output, the second lifting cylinder 53 drives the loading plate 51 to rise, so that the loading column 52 extends into the discharge pipe 44, so that the output pin shaft is sleeved on the loading column 52. After the sleeve is completed, the second lifting cylinder 53 drives the loading plate 51 to descend and reset, waiting for the external robot to pick up the material, and then repeats the above process to complete the feeding work.

[0045] The lifting of the carrier plate 51 can also be driven by an electric cylinder or a screw rod, which is not limited in this embodiment.

[0046] In this embodiment, a plurality of movable wheels 54 are provided on the mounting base 5 ; the movable wheels 54 are four universal wheels with brakes that are evenly arranged at the bottom of the mounting base 5 .
