In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] As Figures 1 to 6 shown, the dual-pin component screening and sorting device 100 of the present invention is used to detect and screen dual-pin components 200.

[0024] The two-pin component 200 has a component body 201 and two pins 202 extending from the component body 201 toward opposite sides.

[0025] The two-pin component screening and sorting device 100 includes two sets of rack components 1 arranged at intervals for conveying the two-pin component 200, baffles 2 arranged on both sides of the rack components 1, a feeding ratchet 3 arranged at one end of the two sets of rack components 1, a driving component 4 for driving the two-pin component 200 to be conveyed from the rack components 1 to the feeding ratchet 3, contact pieces 5 arranged on both sides of the feeding ratchet 3 for electrically connecting with the pins 202, blanking guide plates 6 arranged on both sides of the feeding ratchet 3, tape guiding pieces 7 arranged between the blanking guide plates 6 and the rack components 1, a guiding piece bracket 8 for supporting the tape guiding pieces 7, a plurality of material boxes 9 arranged on the side of the feeding ratchet 3 away from the rack components 1, a pneumatic driving device 10 for driving the plurality of material boxes 9 to move, a detection instrument 101 electrically connected with the contact pieces 5, and a rotation driving member 102 for driving the feeding ratchet 3.

[0026] The rack component 1 includes a fixed rack 11 and a movable rack 12 arranged adjacent to each other. The movable racks 12 of the two sets of rack components 1 are arranged close to each other, and the fixed rack 11 is arranged outside the movable rack 12.

[0027] The fixed rack 11 and the movable rack 12 are provided with inclined grooves 13 for placing the pins 202. Further, the inclined grooves 13 on the fixed rack 11 and the inclined grooves 13 on the movable rack 12 are arranged in a staggered manner, and the position of the inclined groove 13 on the movable rack 12 is lower than the position of the inclined groove 13 on the movable rack 12. When the two-pin component 200 is arranged on the rack component 1, the component body 201 is located at the middle position, and the two pins 202 are respectively lapped in the inclined grooves 13 of the fixed racks 11 on both sides.

[0028] The baffle 2 is arranged outside the fixed rack 11 and has a height higher than that of the inclined groove 13, so as to prevent the two-pin component 200 from disengaging from both sides.

[0029] A plurality of guiding grooves 121 are formed in the movable rack 12, and the guiding grooves 121 extend obliquely upward toward the feeding ratchet 3.

[0030] The driving component 4 includes a linkage lever 41 connecting the movable racks 12 of the two sets of rack components 1, a transmission member 42 abutted against the linkage lever 41 for driving the linkage lever 41 to move obliquely toward the side of the feeding ratchet 3, and a plurality of guiding rods 43 passing through the two movable racks 12.

[0031] The rotation of the transmission member 42 drives the dual-pin component 200 on the fixed rack 11 to lift along the inclined direction and fall into the inclined slot 13 of the adjacent fixed rack 11.

[0032] In this embodiment, the transmission member 42 is a triangular cam 42. The cross-section of the triangular cam 42 is triangular, and the three sides of the triangular cam 42 are sequentially abutted against the linkage lever 41. When the triangular cam 42 rotates one week, the dual-pin components 200 on all the rack assemblies 1 move three inclined slots 13, and there is an interval between each two movements. The interval time can achieve subsequent detection.

[0033] In other embodiments, other forms of transmission members 42 can also be provided so that the dual-pin component 200 moves in the inclined slot 13 of the fixed rack 11 through the inclined movement of the moving rack 12. However, using the triangular cam 42 structure as in this embodiment is simple, and only by controlling the rotation of the triangular cam 42 can the transmission effect be achieved. The transmission member 42, that is, the triangular cam 42, is driven to rotate by the rotation driving member 102.

[0034] The guide rod 43 is connected between the two side baffles 2 and penetrates through the fixed rack 11 and the moving rack 12. The guide slot 121 is used for the guide rod 43 to pass through.

[0035] Specifically, the cooperation mode of the driving assembly 4 and the rack assembly 1 in this embodiment is as follows: The dual-pin component 200 is manually placed in the inclined slot 13 of the fixed rack 11; the rotation of the triangular cam 42 drives the linkage lever 41 and the moving rack 12 to move along the inclined direction. The inclined slot 13 of the moving rack 12 drives the dual-pin component 200 to extend to the highest point along the inclined direction. At this time, one corner of the triangular cam 42 abuts against the linkage lever 41. When continuing to rotate, the triangular cam 42 disengages from the linkage lever 41, and the moving rack 12 slides down to the bottom along the guide slot 121. The dual-pin component 200 vertically falls into the inclined slot 13 of the next fixed rack 11 under the action of gravity; repeat continuously until the dual-pin component 200 disengages from the fixed rack 11 and falls into the dialing ratchet 3.

[0036] When the dual-pin component 200 is in the form of a tape, a tape guide piece 7 and a guide piece bracket 8 are provided between the dialing ratchet 3 and the rack assembly 1 to guide the dual-pin component 200. The tape guide piece 7 includes two upper and lower groups to define the passing of the dual-pin component 200.

[0037] The blanking guide plate 6 is arranged below the contact piece 5 and is spaced from the contact piece 5 for the double-pin component 200 to pass through. The side of the blanking guide plate 6 away from the rack assembly 1 is inclined downward. The feeding ratchet 3 rotates to drive the double-pin component 200 to be electrically connected to the contact piece 5.

[0038] When the double-pin component 200 is on the feeding ratchet 3, the feeding ratchet 3 drives the double-pin component 200 to rotate until the double-pin component 200 falls on the blanking guide plate 6. Then the feeding ratchet 3 drives the double-pin component 200 to move along the blanking guide plate 6 until the pins 202 of the double-pin component 200 are clamped between the blanking guide plate 6 and the contact piece 5, and the detection instrument 101 receives the electrical signal for detection and judgment. In this embodiment, the time for completing one detection and blanking is equal to one-third of the time for the triangular cam 42 to rotate one week.

[0039] The pneumatic driving device 10 drives a plurality of the cartridges 9 to move to receive the double-pin components 200. The cartridges 9 can include a non-conforming cartridge 9 and cartridges 9 of different grades. The pneumatic driving device 10 moves different cartridges 9 to the lower part of the feeding ratchet 3 according to different detection results of the detection instrument 101. After the detection, the double-pin components 200 slide from the blanking guide plate 6 into the corresponding cartridges 9.

[0040] The double-pin component screening and sorting device 100 of the present invention realizes the transmission of the double-pin component 200 by setting the driving assembly 4 and the rack assembly 1; and realizes the detection of the double-pin component 200 during the movement by setting the feeding ratchet 3 and the contact piece 5. The double-pin component screening and sorting device 100 of the present invention realizes the automatic detection and sorting of the double-pin component 200, with fast detection speed, high efficiency, high accuracy rate, and reduced workload of workers.

[0041] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0042] The above-described embodiments only represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent should be subject to the appended claims.
