[0029] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] like Figure 1 The figure shows a specific embodiment of the sorting system for the self-locking components of pneumatic pipe joints provided by the utility model. The sorting system is used to sequentially inspect the self-locking components A of pneumatic pipe joints, specifically to check whether the metal clip A1 in the self-locking components A is properly assembled. Qualified products are transferred to the next station, and unqualified products are transferred to the recycling station.

[0031] The sorting system includes a feeding device 10, a positioning detection device 20 and a dividing device 30 which are arranged in sequence according to the working process; the feeding device 10 is used to supply the self-locking component A in sequence, the positioning detection device 20 is used to detect the self-locking component A supplied by the feeding device 10, and the dividing device 30 distributes the self-locking component A detected by the positioning detection device 20 to different workstations.

[0032] The following section will describe in detail the specific structures and working principles of the feeding device 10, the positioning detection device 20 and the dividing device 30.

[0033] <Feeding device 10>

[0034] like Figure 2As shown, the feeding device 10 includes a feeding support device 11 for receiving the self-locking component A dropped into the vibration disk, and a vibration generating device 12. The feeding support device 11 has a straight material channel 11a. The width of the straight material channel 11a matches the outer diameter of the self-locking component A, so that it can accommodate a self-locking component A along its cross section. The self-locking components A are arranged in sequence on the straight material channel 11a, and are moved in sequence toward the direction close to the positioning detection device 20 under the action of the vibration generating device 12 to feed.

[0035] In one embodiment, the straight material channel 11a is slightly inclined relative to the horizontal plane, and the side thereof close to the positioning detection device 20 is inclined downward. It can gradually move toward the direction close to the positioning detection device 20 under the action of the vibration generating device 12.

[0036] Specifically, a blocking portion 13 is further provided on the upper side of the straight material channel 11a, and the blocking portion 13 is suitable for limiting the longitudinal displacement of the self-locking component A during the vibration process. Specifically, the blocking portion 13 is formed as an L-shaped plate, and one side of the plate surface is extended along the extension direction of the straight material channel 11a.

[0037] <Positioning Detection Device 20>

[0038] like Figure 4 As shown, the positioning detection device 20 includes a positioning fixture 21 and a detection part 22. The positioning fixture 21 can lock the self-locking component A in the detection position, and the detection part 22 can move to the detection position to detect the self-locking component A.

[0039] Specifically, the positioning detection device 20 also includes a positioning support 23, which is located between the output end of the feeding device 10 and the input end of the dividing device 30, and has a transfer channel 23a suitable for the self-locking component A to pass through. The positioning jig 21 and the detection part 22 are respectively located on the upper and lower sides of the positioning support 23. The positioning jig 21 can clamp the self-locking component A located in the transfer channel 23a of the positioning support 23 to achieve the positioning of the self-locking component A. The detection part 22 can move in the up and down directions and detect the self-locking component A located in the transfer channel 23a.

[0040] Among them, the positioning fixture 21 includes a positioning jaw 211 and a positioning cylinder 212 that drives the positioning jaw 211 to move. The positioning jaw 211 is located on opposite sides of the material transfer channel 23a of the positioning support 23. Under the action of the positioning cylinder 212, the positioning jaw 211 moves toward each other to clamp the self-locking component A or moves away from each other to unlock the self-locking component A.

[0041] The detection part 22 includes a detection sensor 221 and a detection cylinder 222 that drives the detection sensor 221 to move. When the positioning fixture 21 clamps and positions the self-locking component A located in the material transfer channel 23a of the positioning support 23, the detection cylinder 222 drives the detection sensor 221 to move toward the direction close to the self-locking component A until it contacts it for detection. After the detection is completed, the detection cylinder 222 drives the detection sensor 221 to move toward the direction close to the self-locking component A.

[0042] The detection sensor 221 is used to detect whether the metal buckle A1 in the self-locking component A is installed in place; Figure 5 、 Figure 6 As shown, the detection sensor 221 includes a first conductive sheet 2211 and a second conductive sheet 2212, each of which is connected to a detection circuit. In the initial state (i.e., the undetected state), the detection circuit is in an open circuit state; the detection sensor 221 does not output a signal; when the detection sensor 221 moves to the detection position, if the self-locking component A is a qualified product, the first conductive sheet 2211 and the second conductive sheet 2212 are respectively in contact with the metal buckle A1 of the self-locking component A, the detection circuit is turned on, and the detection sensor 221 outputs a first signal; if the self-locking component A is a failed product, at least one of the first conductive sheet 2211 and the second conductive sheet 2212 is not in contact with the metal buckle A1 of the self-locking component A, the detection circuit remains in an open state, and the detection sensor 221 outputs a second signal. The first signal and the second signal fed back by the detection sensor 221 can control the operating state of the subsequent workstation (the material dividing device 30).

[0043] Specifically, the detection sensor 221 includes a sensor base 2213 and a cover 2214 fixedly connected to the sensor base 2213. The cover 2214 and the sensor base 2213 define a cavity suitable for accommodating the first conductive sheet 2211 and the second conductive sheet 2212. The first conductive sheet 2211 and the second conductive sheet 2212 are formed into a semi-circular ring structure and are isolated from each other and connected to an insulating guide rod 2215. The insulating guide rod 2215, the first conductive sheet 2211, and the second conductive sheet 2212 extend outside the cover 2214 through a through-hole located on the upper side of the cover 2214. More specifically, the end of the insulating guide rod 2215 is conical and extends outside the first conductive sheet 2211 and the second conductive sheet 2212. When the detection sensor 221 moves upward, the insulating guide rod 2215 first extends into the hollow area of ​​the metal buckle A1 of the self-locking component A to form a guiding effect, so that the first conductive sheet 2211 and the second conductive sheet 2212 can reliably contact the metal buckle A1, thereby improving detection accuracy.

[0044] The insulating guide rod 2215, the first conductive sheet 2211, and the second conductive sheet 2212 form a sliding assembly that can slide along the centerline of the through-hole of the cover 2214. An elastic member (not shown) is disposed between the sliding assembly and the sensor base 2213. When the detection sensor 221 moves to contact the self-locking assembly A, the elastic member provides a certain amount of movement buffer between the first conductive sheet 2211 and the second conductive sheet 2212, ensuring full contact with the metal buckle A1 of the self-locking assembly A, thereby improving the detection accuracy of the detection sensor 221.

[0045] More specifically, the sensor base 2213 comprises a rectangular plate 2213a and a cylindrical base 2213b positioned atop the rectangular plate 2213a. The detection cylinder 222 acts on the underside of the rectangular plate 2213a, and the cover 2214 is connected to the cylindrical base 2213b via a plug-in connection. The cover 2214 comprises a cover plate and a cylindrical body, with setscrews securing the cylindrical body 2213b to the cover 2214. Specifically, the cover 2214 is comprised of a first cover half 2214a and a second cover half 2214b, secured together by screws. The first half cover 2214a and the second half cover 2214b are provided with openings on their cylinders respectively, and the first conductive sheet 2211 and the second conductive sheet 2212 are electrically connected to the detection circuit via the connecting portions 2216 passing through the openings of the first half cover 2214a and the second half cover 2214b respectively.

[0046] like Figure 4 As shown, the positioning detection device 20 also includes a position detection unit 24, which is mounted on the positioning support 23 and is used to detect whether the self-locking assembly A has moved into position. Specifically, the position detection unit 24 is a laser position sensor, which includes a transmitter and a receiver, respectively located on either side of the material transfer channel 23a of the positioning support 23. The transmitter is used to transmit a laser signal toward the receiver, and a detection signal is sent when there is an obstruction between the two.

[0047] The working principle of the positioning detection device 20 is as follows:

[0048] When the self-locking component A is transported to the transfer channel 23a of the positioning support 23 in the straight material channel 11a of the feeding device 10, the light signal of the in-place detection part 24 is blocked. After the in-place detection part 24 sends an in-place detection signal, the control unit controls the positioning fixture 21 to move, specifically, controls the positioning jaws 211 to clamp the self-locking component A located in the transfer channel 23a to keep it in a fixed state. After the positioning jaws 211 are clamped, the detection part 22 is controlled to move upward, so that the first conductive plate 2211 and the second conductive plate 2212 of the detection sensor 221 are moved to a position where they can reliably contact and connect with the metal buckle A1 of the self-locking component A, that is, the elastic part in the detection sensor 221 is in a compressed state. At this time, if the self-locking component A is qualified, the first conductive sheet 2211 and the second conductive sheet 2212 are respectively in contact with the metal buckle A1, the detection circuit is turned on, and the detection sensor 221 outputs a first signal. If the self-locking component A is unqualified, at least one of the first conductive sheet 2211 and the second conductive sheet 2212 is not in contact with the metal buckle A1 of the self-locking component A, the detection circuit remains off, and the detection sensor 221 outputs a second signal. The signal fed back by the detection sensor 221 can continue to control the operating state of the material dispensing device 30.

[0049] <Material distribution device 30>

[0050] like Figure 7 As shown, the material distribution device 30 includes a rotatable material distribution tray 31, which is provided with a receiving area 31a for accommodating the self-locking assembly A. Specifically, the receiving area 31a is a receiving groove formed at the end of the material distribution tray 31. The material distribution tray 31 is provided with multiple receiving grooves along its circumference. In the initial state, the receiving grooves are arranged opposite to the material transfer channel 23a on the positioning support member 23 of the positioning detection device 20. After being detected by the positioning detection device 20, the self-locking assembly A enters the receiving area 31a of the material distribution tray 31 to proceed to the next step of material distribution.

[0051] Specifically, the material distribution plate 31 rotates in a first direction or a second direction under the action of the material distribution drive device 32. When the positioning detection device 20 sends a first signal, that is, when the self-locking component A is a qualified product, the material distribution drive device 32 is controlled to rotate the material distribution plate 31 in the first direction and transport it to the next station for the next step of operation. When the positioning detection device 20 sends a second signal, that is, when the self-locking component A is a failed product, the material distribution drive device 32 is controlled to rotate the material distribution plate 31 in the second direction and transport it to the recycling station for recycling of failed parts.

[0052] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
