[0035] As shown in Figure 2 , the buckle supply mechanism 20 is arranged on the support table 12, and includes a storage box 21, a vibration disc 22, a discharge passage 23, and a buckle moving unit 24.

[0036] The storage box 21 can provide the buckle 1 to be mounted to the vibration disc, and includes a storage box body 211 and a discharge port 212 arranged at the bottom of the storage box body 211. The buckle 1 stored in the storage box body 211 at the discharge port 212 falls into the vibration disc 22 through the discharge port 212.

[0037] The vibrating disc 22 is arranged below the discharge port 212 and can output the buckles 1 in an oriented arrangement. The outlet of the vibrating disc 22 is connected to one end of the discharge channel 23, and the discharge channel 23 is adapted to the buckle 1. The buckle 1 is arranged in a line under the action of the vibrating disc 22 and moves orderly along the discharge channel 23.

[0038] Figure 3 FIG. 4 is a structural schematic diagram of a buckle moving unit in an embodiment of the present application, Figure 4 FIG. 5 is a top view of the buckle moving unit in an embodiment of the present application.

[0039] The buckle moving unit 24 is arranged at the other end of the discharge channel 23 and can move the buckle from the discharge channel 23 to a predetermined pickup position. As shown in FIG. 6, Figure 3 、 4 The buckle moving unit 24 includes a baffle 241, a buckle receiving assembly 242, and a buckle limiting assembly 243.

[0040] The buckle receiving assembly 242 can receive the buckle output from the outlet of the discharge channel 23 and includes a buckle receiving plate 2421 and a receiving plate driving member 2422.

[0041] The buckle receiving plate 2421 is movably arranged at the outlet of the discharge channel 23, and the buckle receiving plate 2421 is provided with two buckle receiving grooves 2423 parallel to each other. Each buckle receiving groove 2423 includes an arc-shaped section 2423a close to the baffle 241, a straight section 2423b extending away from the baffle 241, and a transition section 2423c in communication with the arc-shaped section 2423a and the straight section 2423b at both ends. The opening width of the arc-shaped section 2423a close to the baffle is adapted to the diameter of the buckle, facilitating the buckle to enter the buckle receiving groove 2423. The arc-shaped section 2423a close to the transition section 2423c has an arc close to the side surface of the buckle, and the width of the transition section 2423c is smaller than the diameter of the buckle, which can limit the buckle and avoid the buckle entering the straight section 2423b of the buckle receiving groove 2423.

[0042] The receiving plate driving member 2422 is connected to the buckle receiving plate 2421 and can drive the buckle receiving plate 2431 to move in a direction perpendicular to the discharge channel 23. In this embodiment, the receiving plate driving member 2422 is a servo cylinder.

[0043] The baffle 241 is arranged on the support table 12 along the moving direction of the buckle receiving plate 2421 and is perpendicular to the buckle receiving plate 2421, which can limit the buckle in the buckle receiving groove.

[0044] The buckle limiting assembly 243 can further limit the buckle on the buckle receiving plate 2421 and includes a limiting fork plate 2431 and a fork plate driving member 2432.

[0045] The limiting fork plate 2431 is movably arranged on the buckle receiving plate 2421, and includes a fork plate body 2431a and a fork head 2431b. The width of the fork plate body 2431a is adapted to the straight section 2423b of the buckle receiving groove 2423. The fork head 2431b is arranged on one end of the fork plate body 2431a close to the arc section 2423a. The width of the fork head 2431b is adapted to the transition section 2423c, and the width of the fork plate body 2431a is greater than the width of the fork head 2431b, which can limit the moving position of the limiting fork plate 2431 and avoid the fork plate body 2431a entering the arc section 2423a. The fork head 2431b has a U-shaped buckle limiting groove 2431c which is adapted to the clamping groove of the buckle bottom, and can further limit the buckle in the arc section 2423a.

[0046] The number of the limiting fork plates 2431 is two, which are matched with the two buckle receiving grooves 2423 respectively. The fork plate driving member 2432 is connected with the fork plate bodies 2431a of the two limiting fork plates 2431, and can drive the two limiting fork plates 2431 to move synchronously, so that the fork plate bodies 2431a move along the straight section 2423b of the buckle receiving groove 2423, and drive the fork heads 2431b to approach or move away from the buckle in the arc section 2423a. In the embodiment, the fork plate driving member 2432 is a gas cylinder.

[0047] Figure 5 is a structure schematic view of the feeding detection unit in the embodiment of the present application, Figure 6 is a top view of the feeding detection unit in the embodiment of the present application.

[0048] As shown in Figure 5 , 6 The buckle feeding mechanism 20 further includes a feeding detection unit 25 which can detect whether the feeding is in place, and at least includes two groups of sensors 251. One group of sensors 251a is used to sense whether there is a buckle at the outlet of the feeding channel 23, and the other group of sensors 251b is used to sense whether there is a buckle at the predetermined picking position.

[0049] The buckle feeding mechanism 20 further comprises a waste recycling unit 26. The waste recycling unit 26 is capable of recycling the buckles that are not fed in place, and comprises a waste hopper 261, a reject push plate 262, a push plate driving member 263, a waste chute 264, and a waste collection barrel 265. The waste hopper 261 is fixed on one side of the support table 12. The reject push plate 262 is movably arranged above the upper opening of the waste hopper 261, and is perpendicular to the buckle receiving plate 2421, with the bottom of the reject push plate 262 being higher than the upper surface of the buckle receiving plate 2421. The push plate driving member 263 is capable of driving the reject push plate 262 to move, so that the reject push plate 262 is in contact with the upper part of the buckle, thereby pushing the buckle in the buckle receiving groove 2423 into the waste hopper 261. In the embodiment, the push plate driving member 263 is a pneumatic cylinder. The waste chute 264 is arranged obliquely, with the upper end being directly below the waste hopper 261 and the lower end being above the opening of the waste collection barrel 265. The buckle in the waste hopper 261 falls into the waste chute 264 below under the action of gravity, and then slides into the waste collection barrel 265 along the waste chute 264.

[0050] During feeding, the buckles are output after directional arrangement under the action of the vibration disc 22, and move along the discharge channel 23 to the buckle moving unit 24. The buckle receiving plate 2421 moves under the drive of the receiving plate driving member 2422, so that the arc-shaped section 2423a of one of the buckle receiving grooves 2423 on the buckle receiving plate 2421 is aligned with the outlet of the discharge channel 23. The buckle moves from the outlet of the discharge channel 23 to the buckle receiving groove 2423 under the action of the vibration disc 22, and stays on the arc-shaped section 2423a. The sensor 251a senses whether there is a buckle at the outlet of the discharge channel 23. If there is a buckle, the buckle is not successfully transferred to the buckle receiving groove 2423, and the vibration disc 22 continues to feed the buckle, so that the buckle near the outlet of the discharge channel 23 is detached from the discharge channel 23 and transferred to the buckle receiving groove 2423.

[0051] After a snap-on is successfully transferred to the snap-on receiving groove 2423, the receiving plate drive 2422 drives the snap-on receiving plate 2421 to move again, so that the arc-shaped segment 2423a of one snap-on receiving groove 2423 is aligned with the outlet of the discharge channel 23 to receive the next snap-on. After receiving two snap-on pieces to be installed, the receiving plate drive 2422 drives the snap-on receiving plate 2421 to move along the baffle 241, moving the two snap-on pieces to the predetermined pick-up position. The fork drive 2432 drives the limiting fork 2431 to move towards the snap-on piece. The snap-on piece stops in the snap-on receiving groove 2423 under the obstruction of the baffle 241. At the same time, the fork head 2431b engages with the engaging groove at the bottom of the snap-on piece, so that the snap-on piece is fixed in the predetermined pick-up position under the combined action of the baffle 241 and the limiting fork 2431, so that it can be picked up by the snap-on installation mechanism 30. Another set of sensors 251b senses whether there is a clip at the predetermined pick-up position to determine whether the clip has been successfully removed. If the pick-up fails, the receiving plate drive 2422 drives the clip receiving plate 2421 to move, so that the clip receiving groove 2423 with the unremoved clip is aligned with the waste funnel 261. The push plate drive 263 drives the discard push plate 262 to push the clip into the waste funnel 261, so that the clips fall into the waste collection bin 265.

[0052] Figure 7 This is a schematic diagram of the snap-fit ​​installation mechanism in an embodiment of the present invention.

[0053] The snap-fit ​​mounting mechanism 30 is mounted on the frame 11, such as... Figure 7 As shown, the buckle mounting mechanism 30 includes a robotic arm 31, a buckle mounting component 32, a connecting frame 33 for the buckle mounting component, and a buckle detection unit 34.

The second horizontal rotating arm 3131 is rotatably connected to the first horizontal rotating arm 3121, and the second horizontal rotating driving member is connected to the second horizontal rotating arm 3131 and can drive the second horizontal rotating arm 3131 to rotate, thereby further expanding the activity range of the manipulator in the horizontal direction and facilitating the processing of different points.

[0058] The lifting unit 314 for buckle installation is arranged on the second horizontal rotating unit 313 for buckle installation and can drive the buckle installation member 32 to lift. In the embodiment, the lifting unit 314 for buckle installation comprises a lifting motor for buckle installation, a lifting connecting rod 3142 for buckle installation and a lifting guide rod 3143 for buckle installation.

[0059] The lifting motor for buckle installation is used to drive the lifting connecting rod 3142 for buckle installation to lift.

[0064] As shown in Figure 8 , the bottom of the buckle installation member 32 has a buckle fixing cavity 321, and the shape and size of the buckle fixing cavity 321 are matched with the shape and size of the buckle. The buckle fixing cavity 321 and the buckle are in interference fit, and the buckle is fixed by friction. After the buckle is installed in place, the lifting unit 314 for buckle installation drives the buckle installation member 32 to rise, so that the buckle is separated from the buckle installation member 32. The structure is simple, convenient to use and easy to manufacture.

[0065] The connecting frame 33 for buckle mounting is mounted on the lifting connecting rod 3142 for buckle mounting, and can connect the buckle mounting piece 32. In the embodiment, the buckle mounting piece 32 is provided in two, and the two buckle mounting pieces 32 are arranged in parallel along the length direction of the lifting connecting rod 3142 for buckle mounting on the connecting frame 33 for buckle mounting, so that two buckles can be taken at one time, and the processing efficiency can be effectively improved.

[0066] When taking the buckle, the manipulator 31 moves to make the buckle mounting piece 32 above the predetermined taking position, and the two buckle mounting pieces 32 are respectively aligned with the buckles in the two buckle receiving grooves 2423, then the lifting unit 314 for buckle mounting drives the buckle mounting piece 32 to descend, so that the upper part of the buckle is clamped into the buckle fixing cavity 321 and fixed. Finally, the limiting fork plate 2431 retreats, the lifting unit 314 for buckle mounting drives the buckle mounting piece 32 to ascend, and the buckle is lifted to the predetermined lifting position.

[0070] The detection motor 341 for buckle mounting is connected with the buckle mounting piece 32 through the detection transmission assembly 342, so as to drive the buckle mounting piece 32 to rotate. In the embodiment, the detection motor 341 for buckle mounting is a servo motor, which can feed back the resistance received during rotation to the controller and other upper devices, and then further judge whether the buckle is mounted in place according to the size of the resistance.

[0071] In the embodiment, the detection transmission assembly 342 includes a driving wheel 3421, two driven wheels 3422, a synchronous belt 3423 and a tensioning wheel 3424. The driving wheel 3421 is connected with the output end of the detection motor 341 for buckle mounting, and the two driven wheels 3422 are respectively fixedly connected with the two buckle mounting pieces 32. The tensioning wheel 3424 is used for tensioning the synchronous belt 3423, so as to avoid the transmission slip to affect the transmission effect.

[0072] In the embodiment, the buckle mounting groove with a side opening is arranged at the buckle mounting point on the automobile door panel.

[0073] When installing, the mechanical hand 31 drives the buckle to move, and the lower part of the buckle is clamped into the buckle mounting groove from the side opening to be fixed.

[0074] When detecting, under the driving of the buckle mounting detection motor 341, the driving wheel 3421 drives the driven wheel 3422 to rotate through the synchronous belt 3423, so that the buckle mounting part 32 also rotates, thereby applying a torsional force to the buckle, and then judging whether the buckle is installed in place according to the feedback result of the servo motor, which can effectively improve the machining precision, reduce the waste rate, and protect the product quality.

[0075] After the buckle is installed in place, the buckle mounting lifting unit 314 drives the buckle mounting part 32 to rise and separate from the buckle, thereby completing the installation of the buckle.

[0076] In the embodiment, in order to further improve the working efficiency of the buckle mounting station, the number of the buckle feeding mechanism and the buckle mounting mechanism is set to two.
