[0048] The buckle mounting control mechanism 50 can control the buckle feeding mechanism 20 and the buckle mounting mechanism 30 to operate. In the present embodiment, the buckle mounting control mechanism 50 adopts a controller in the prior art.

[0049] In the embodiment, the buckle is a rotating body, and the bottom has a clamping groove matched with the door plate.

[0050] The support frame 10 comprises a frame 11 and a support table 12 arranged on one side of the frame 11.

[0051] Figure 4 is a structural schematic view of the buckle feeding mechanism in the embodiment of the present application.

[0052] As shown in Figure 4 , the buckle feeding mechanism 20 is arranged on the support table 12 and comprises a storage box 21, a vibrating disc 22, a discharging channel 23 and a buckle moving unit 24.

[0053] The storage box 21 can provide the vibrating disc with the buckle 1 to be installed and comprises 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 vibrating disc 22 through the discharge port 212.

[0054] The vibrating disc 22 is arranged below the discharge port 212, is electrically connected with the buckle installation control mechanism 50 and can output the buckle 1 after directional arrangement under the control of the buckle installation control mechanism 50.

[0055] In the embodiment, the discharging channel 23 is a linear groove body matched with the buckle in shape. One end of the discharging channel 23 is connected with the outlet of the vibrating disc 22, and the buckle 1 is arranged in a line under the action of the vibrating disc 22 and orderly moves along the discharging channel 23 to the other end.

[0056] Figure 5 is a structural schematic view of the buckle moving unit in the embodiment of the present application, Figure 6 is a top view of the buckle moving unit in the embodiment of the present application.

[0057] The buckle moving unit 24 is arranged at the other end of the discharging channel 23 and can move the buckle from the discharging channel 23 to a predetermined pickup position. As shown in Figure 5 , 6 , the buckle moving unit 24 comprises an auxiliary limiting baffle 241, a buckle receiving assembly 242 and a buckle limiting assembly 243.

[0058] The buckle receiving assembly 242 comprises a buckle receiving plate 2421 and a receiving plate driving member 2422. The buckle receiving plate 2421 is movably arranged at the outlet of the discharge channel 23, and in the embodiment, the moving direction of the buckle receiving plate 2421 is perpendicular to the conveying direction of the buckle in the discharge channel 23. Two buckle receiving grooves 2423 parallel to each other are formed on the buckle receiving plate 2421. In the embodiment, the length direction of the two buckle receiving grooves 2423 is parallel to the conveying direction of the buckle in the discharge channel 23, facilitating the receiving of the buckle output from the outlet of the discharge channel 23.

[0059] The auxiliary limiting baffle 241 is arranged on the support table 12 along the moving direction of the buckle receiving plate 2421. The auxiliary limiting baffle 241 is located on the side of the buckle receiving plate 2421 close to the discharge channel 23 and is perpendicular to the buckle receiving plate 2421, and can cooperate with the buckle receiving assembly 242 to limit the buckle in the buckle receiving groove in the transverse direction.

[0060] Each buckle receiving groove 2423 comprises an arc-shaped section 2423a close to the auxiliary limiting baffle 241, a straight section 2423b extending away from the auxiliary limiting baffle 241, and a transition section 2423c in communication with the arc-shaped section 2423a and the straight section 2423b at two ends thereof. The opening width of the arc-shaped section 2423a close to the end of the auxiliary limiting baffle 241 is adapted to the diameter of the buckle, facilitating the entry of the buckle into the buckle receiving groove 2423; the end of 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 entry of the buckle into the straight section 2423b of the buckle receiving groove 2423.

[0061] The receiving plate driving member 2422 is electrically connected with the buckle installation control mechanism 50, and the output end of the receiving plate driving member 2422 is connected with the buckle receiving plate 2421, which can drive the buckle receiving plate 2431 to move along the direction perpendicular to the discharge channel 23 under the control of the buckle installation control mechanism 50. In the embodiment, the receiving plate driving member 2422 is a servo cylinder.

[0062] The buckle limiting assembly 243 can further limit the buckle on the buckle receiving plate 2421, comprising a limiting fork plate 2431 and a fork plate driving member 2432.

[0063] A limiting fork plate 2431 is movably mounted on a snap-fit ​​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 segment 2423b of the snap-fit ​​receiving groove 2423. The fork head 2431b is located at one end of the fork plate body 2431a near the curved segment 2423a. The width of the fork head 2431b is adapted to the transition segment 2423c, and the width of the fork plate body 2431a is greater than the width of the fork head 2431b, which can restrict the movement position of the limiting fork plate 2431 and prevent the fork plate body 2431a from entering the curved segment 2423a. The fork head 2431b has a U-shaped latching groove 2431c, which matches the engagement groove at the bottom of the latch, enabling further lateral and vertical limiting of the latch within the arc-shaped segment 2423a. In this embodiment, the number of limiting fork plates 2431 is also set to two, corresponding to the two latch receiving grooves 2423 respectively.

[0064] The fork drive unit 2432 is electrically connected to the snap-fit ​​mounting control mechanism 50. The output end of the fork drive unit 2432 is simultaneously connected to the fork body 2431a of both limiting fork plates 2431. Under the control of the snap-fit ​​mounting control mechanism 50, it can drive the two limiting fork plates 2431 to move synchronously along the two snap-fit ​​receiving grooves 2423, causing the fork body 2431a to move along the straight section 2423b of the snap-fit ​​receiving groove 2423, thus moving the fork head 2431b closer to or further away from the snap-fit ​​within the arc-shaped section 2423a. In this embodiment, the fork drive unit 2432 is a cylinder.

[0065] Figure 7 This is a schematic diagram of the material feeding detection unit in an embodiment of the present invention. Figure 8 This is a top view of the feeding detection unit in an embodiment of the present invention.

[0066] like Figure 7 , 8 As shown, the snap-fit ​​feeding mechanism 20 also includes a feeding detection unit 25, which can detect whether the feeding is successful. It includes three sets of sensors 251: a first sensor 251a, a second sensor 251b, and a third sensor 251c, all electrically connected to the snap-fit ​​installation control mechanism 50. The first sensor 251a detects whether there is a snap-fit ​​at the outlet of the discharge channel 23, and the second sensor 251b detects whether there is a snap-fit ​​at the predetermined pick-up position.

[0067] The snap-fit ​​feeding mechanism 20 also includes a waste recycling unit 26. The waste recycling unit 26 is capable of recycling snap-fits that have not been successfully fed into the snap-fit ​​receiving groove 2423, and includes a waste funnel 261, a discard push plate 262, a push plate drive component 263, a waste chute 264, and a waste collection bin 265.

[0068] A waste funnel 261 is arranged on the support table 12. A waste push plate 262 is movably arranged above the upper opening of the waste funnel 261. In the embodiment, the waste push plate 262 is perpendicular to the buckle receiving plate 2421, and the bottom of the waste push plate 262 is higher than the upper surface of the buckle receiving plate 2421.

[0069] The push plate driving member 263 is electrically connected with the buckle installation control mechanism 50, and can drive the waste push plate 262 to move under the control of the buckle installation control mechanism 50, so that the waste push plate 262 contacts the upper part of the buckle, and the buckle in the buckle receiving groove 2423 is pushed into the waste funnel 261. In the embodiment, the push plate driving member 263 is a pneumatic cylinder.

[0070] In the embodiment, the waste chute 264 is a U-shaped channel with an upward opening. In order to cooperate with other structures in the buckle automatic installation device 100, such as the support table 12, and facilitate installation, the waste chute 264 can be composed of multiple channel segments, which are arranged in series. The waste chute 264 is arranged on the support table 12 as a whole, and the upper end of the waste chute 264 is located directly below the waste funnel 261, and the lower end is located above the opening of the waste collection barrel 265. The buckle in the waste funnel 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.

[0071] During feeding, the buckle is output after directional arrangement under the action of the vibration disc 22, and moves to the buckle moving unit 24 along the discharge channel 23. The buckle receiving plate 2421 moves under the drive of the receiving plate driving member 2422, so that the arc-shaped segment 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 stops at the arc-shaped segment 2423a. The buckle installation control mechanism 50 controls the first sensor 251a to detect whether there is a buckle at the outlet of the discharge channel 23. If there is a buckle, the buckle has not been successfully transferred to the buckle receiving groove 2423, and the buckle installation control mechanism 50 controls the vibration disc 22 to continue to convey the buckle, so that the buckle near the outlet of the discharge channel 23 is separated from the discharge channel 23 and transferred to the buckle receiving groove 2423.

[0072] After one buckle is successfully transferred to the buckle receiving groove 2423, the buckle installation control mechanism 50 controls the receiving plate driving member 2422 to drive the buckle receiving plate 2421 again to move, so that the arc-shaped section 2423a of the other buckle receiving groove 2423 is aligned with the outlet of the discharge channel 23 to receive the next buckle. After receiving two buckles to be installed, the buckle installation control mechanism 50 controls the receiving plate driving member 2422 to drive the buckle receiving plate 2421 to move along the auxiliary limiting baffle 241, so that the two buckles are moved to the predetermined pickup position. Then, the buckle installation control mechanism 50 controls the fork plate driving member 2432 to drive the limiting fork plate 2431 to move towards the buckle, and the buckle stays in the buckle receiving groove 2423 under the blockage of the auxiliary limiting baffle 241, while the fork head 2431b is engaged with the buckle groove at the bottom of the buckle, so that the buckle is fixed at the predetermined pickup position under the joint action of the auxiliary limiting baffle 241 and the limiting fork plate 2431, for the buckle installation mechanism 30 to pick up. The buckle installation control mechanism 50 controls the second sensor 251b to detect whether there is a buckle at the predetermined pickup position, and when the detection result is yes, it means that the feeding is unsuccessful and the buckle is not successfully picked up by the buckle installation mechanism 30. The buckle installation control mechanism 50 first controls the receiving plate driving member 2422 to drive the buckle receiving plate 2421 to move, so that the buckle receiving groove 2423 with the buckle not picked up is aligned with the waste hopper 261, and then controls the push plate driving member 263 to drive the waste push plate 262 to push the buckle into the waste hopper 261, so that the buckles are concentrated and fall into the waste collection barrel 265.

[0073] In this embodiment, in order to further improve the working efficiency of the buckle installation station, the number of the buckle feeding mechanism 20 and the buckle installation mechanism 30 is set to two. The waste recovery units 26 in the two buckle feeding mechanisms 20 share the same waste collection barrel 265.

[0074] Figure 9 is a structural schematic view of the buckle installation mechanism in the embodiment of the present application.

[0075] The buckle installation mechanism 30 is arranged on the rack 11, as shown in Figure 9 The buckle installation mechanism 30 includes a mechanical arm 31, a buckle installation member 32, a buckle installation member connecting frame 33, and a buckle detection unit 34.

[0076] The mechanical arm 31 is electrically connected with the buckle installation control mechanism 50, and includes a mechanical arm fixed seat 311, a buckle installation first horizontal rotating unit 312, a buckle installation second horizontal rotating unit 313, and a buckle installation lifting unit 314.

[0077] The mechanical arm fixed seat 311 is installed on the upper part of the rack 11.

[0078] The first horizontal rotating unit 312 for buckle installation is rotatably arranged on the mechanical arm fixing seat 311, and comprises a first horizontal rotating arm 3121 and a first horizontal rotating driving member. The first horizontal rotating driving member is connected with the first horizontal rotating arm 3121 and can drive the first horizontal rotating arm 3121 to rotate in the horizontal direction.

[0079] The second horizontal rotating unit 313 for buckle installation is rotatably arranged on the first horizontal rotating unit 312 for buckle installation. The second horizontal rotating unit 313 for buckle installation comprises a second horizontal rotating arm 3131 and a second horizontal rotating driving member. The second horizontal rotating arm 3131 is rotatably connected with the first horizontal rotating arm 3121, and the second horizontal rotating driving member is connected with the second horizontal rotating arm 3131 and can drive the second horizontal rotating arm 3131 to rotate, so as to further expand the activity range of the mechanical arm in the horizontal direction and facilitate the assembly work at different positions.

[0080] 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.

[0081] The lifting motor for buckle installation can drive the lifting connecting rod 3142 for buckle installation to lift.

[0082] One end of the lifting connecting rod 3142 for buckle installation is arranged on the second horizontal rotating arm 3131, and the other end is connected with the buckle installation member 32 through the connecting frame 33 for buckle installation.

[0083] The number of the lifting guide rods 3143 for buckle installation is two, which are parallel with the lifting connecting rod 3142 for buckle installation and can guide and limit the lifting, so as to effectively improve the stability and accuracy of the machining.

[0084] The buckle installation mechanism 30 comprises at least one buckle installation member 32 arranged on the mechanical arm 31 and capable of abutting against the buckle and moving under the driving of the mechanical arm 31, so as to take and install the buckle.

[0085] Figure 10 is a structural schematic view of the buckle installation member in the embodiment of the application.

[0086] As Figure 10As shown, the bottom of the snap-fit ​​mounting component 32 has a snap-fit ​​fixing cavity 321, the shape and size of which are adapted to the shape and size of the snap-fit. The snap-fit ​​fixing cavity 321 and the snap-fit ​​are interference-fitted, and the snap-fit ​​is fixed by friction. After the snap-fit ​​is installed in place, the snap-fit ​​mounting lifting unit 314 lifts the snap-fit ​​mounting component 32, thus separating the snap-fit ​​from the snap-fit ​​mounting component 32. The structure is simple, easy to use, and easy to manufacture.

[0087] The connecting bracket 33 for the snap-fit ​​mounting component is mounted on the lifting connecting rod 3142 for snap-fit ​​mounting, and can connect the snap-fit ​​mounting component 32. In this embodiment, there are two snap-fit ​​mounting components 32, which are arranged parallel to each other on the connecting bracket 33 along the length of the lifting connecting rod 3142 for snap-fit ​​mounting. This allows for the removal of two snap-fit ​​components at once, which can effectively improve assembly efficiency.

[0088] During item retrieval, the buckle installation control mechanism 50 first controls the robotic arm 31 to move, positioning the buckle mounting component 32 above the predetermined retrieval position, with the two buckle mounting components 32 aligned with the buckles 1 in the two buckle receiving grooves 2423 respectively. Then, the buckle installation control mechanism 50 controls the buckle installation lifting unit 314 to lower the buckle mounting component 32, causing the upper part of the buckle 1 to engage with and be fixed in the buckle fixing cavity 321. Due to the limiting effect of the buckle limiting component 243 on the buckle 1, the upper part of the buckle 1 is less likely to shake or shift when engaged in the buckle fixing cavity 321, effectively improving the success rate of item retrieval. Finally, the buckle installation control mechanism 50 controls the limiting fork plate 2431 to retract, causing the fork head 2431b to separate from the engagement groove at the bottom of the buckle, releasing the vertical limitation on the buckle. The buckle installation lifting unit 314 then raises the buckle mounting component 32, lifting the buckle 1 to the predetermined lifting position.

[0089] In this embodiment, the third sensor 251c of the feeding detection unit 25 can detect whether there is a latch 1 at the predetermined lifting position. If there is no latch 1 at the predetermined lifting position, the feeding is unsuccessful. The latch 1 that was not successfully removed by the latch mounting part 32 in the latch receiving groove 2423 is recycled by the waste recycling unit 26.

[0090] Figure 11 This is a schematic diagram of the buckle detection unit in an embodiment of the present invention.

[0091] like Figure 11 As shown, the snap-fit ​​detection unit 34 is mounted on the snap-fit ​​mounting bracket 33 and is capable of detecting whether the snap-fit ​​is properly installed. The snap-fit ​​detection unit 34 includes a snap-fit ​​installation detection motor 341 and a detection transmission assembly 342.

[0092] The detection motor 341 for snap-fit ​​installation is connected to the snap-fit ​​mounting component 32 via the detection transmission assembly 342, thereby driving the snap-fit ​​mounting component 32 to rotate under the control of the snap-fit ​​installation control mechanism 50. In this embodiment, the detection motor 341 for snap-fit ​​installation is a servo motor, which can feed back the torque during rotation to the snap-fit ​​installation control mechanism 50, and then further determine whether the snap-fit ​​is installed in place based on the magnitude of the torque.

[0093] In this embodiment, the detection transmission assembly 342 includes a drive pulley 3421, two driven pulleys 3422, a timing belt 3423, and a tension pulley 3424. The drive pulley 3421 is connected to the output end of the detection motor 341 for snap-fit ​​installation, and the two driven pulleys 3422 are respectively fixedly connected to two snap-fit ​​mounting parts 32. The tension pulley 3424 is used to tension the timing belt 3423 to prevent slippage during transmission and thus avoid affecting the transmission effect.

[0094] In this embodiment, the car door panel has multiple predetermined installation points, and each predetermined installation point has a side-opening buckle mounting groove that can engage with the lower part of the buckle.

[0095] During installation, the robotic arm 31 moves the buckle, causing the lower part of the buckle to engage with the buckle mounting groove from the side opening and be fixed in place.

[0096] During testing, the buckle installation control mechanism 50 controls the buckle installation detection motor 341, which drives the drive wheel 3421, which in turn drives the driven wheel 3422 to rotate via the synchronous belt 3423. This causes the buckle installation component 32 to rotate as well, thereby applying a torsional force to the buckle. Then, based on the feedback from the servo motor, it is determined whether the buckle has been successfully installed on the door panel. This effectively improves processing accuracy, reduces scrap rate, and ensures the quality of finished products.

[0097] If the buckle detection unit 34 detects that the buckle has been installed on the door panel, the buckle installation control mechanism 50 controls the buckle installation lifting unit 314 to drive the buckle installation part 32 to rise and separate from the buckle, thereby completing the installation of the buckle at a predetermined installation point.

[0098] If the buckle detection unit 34 detects that the buckle has not been installed successfully, the robotic arm 31 will move the buckle to the waste receiving mechanism 40.

[0099] Figure 12 This is a schematic diagram of the waste receiving mechanism in an embodiment of the present invention. Figure 13 This is a top view of the waste receiving mechanism in an embodiment of the present invention. Figure 14 This is a front view of the waste receiving mechanism in an embodiment of the present invention. Figure 15 yes Figure 14 A magnified view of the structure within frame A.

[0100] like Figures 12 to 15As shown, the waste receiving mechanism 40 includes a waste receiving frame 41, a waste receiving component 42, a waste collecting component 43, a guide baffle 44, a waste chute, and a waste collecting bucket.

[0101] The waste receiving frame 41 includes a connecting part 411 and a supporting part 412. The connecting part 411 is bolted to the frame 11, and the supporting part 412 is connected to the bottom of the connecting part 411.

[0102] like Figures 3 to 6 As shown, the waste receiving component 42 is mounted on the support portion 412 of the waste receiving bracket 41 and has a waste receiving groove 421 adapted to the buckle 1. In this embodiment, the waste receiving component 42 is made of structural steel, which is low in cost and easy to manufacture. The waste receiving groove 421 is located at the top of the waste receiving component 42 and is arranged in a horizontal direction. In order for the waste receiving component 42 to stably receive the buckle 1, the length of the waste receiving groove 421 should be greater than or equal to one times the maximum diameter of the buckle 1. In this embodiment, the length of the waste receiving groove 421 is set to three times the maximum diameter of the buckle 1, so that the three buckles 1 can be arranged sequentially on the waste receiving component 42 along the waste receiving groove 421. One end of the waste receiving groove 421 is provided with a buckle inlet 4211 for the buckle 1 to be inserted, and the other end is provided with a buckle outlet 4212 for the buckle 1 to be released. The waste receiving groove 421 engages with the engagement groove at the bottom of the buckle 1, thereby vertically limiting the buckle 1 on the waste receiving part 42.

[0103] In this embodiment, since there are two snap-fit ​​mounting pieces 32, the number of waste receiving pieces 42 is also set to two. The two waste receiving pieces 42 are parallel to each other, and the distance between the two waste receiving pieces 42 is equal to the distance between the two snap-fit ​​mounting pieces 32. This allows the two waste receiving pieces 42 to simultaneously receive the snap-fit ​​pieces 1 on the two snap-fit ​​mounting pieces 32, thereby shortening the time for collecting waste snap-fit ​​pieces and improving processing efficiency.

[0104] The guide baffle 44 is provided on the support part 412 of the waste receiving frame, located outside the buckle inlet 4211, and the top surface of the guide baffle 44 is parallel to the waste receiving groove 421. When the buckle 1 approaches the buckle inlet 4211, it can abut against the bottom of the buckle 1 to guide and limit the buckle 1, so that the buckle 1 can be inserted into the waste receiving groove 421.

[0105] The waste collecting member 43 can collect the buckle 1 which is dropped from the buckle outlet 4212 when the waste receiving groove is full. In this embodiment, the waste collecting member 43 is a funnel-shaped structure with a large top and a small bottom, has a collecting inlet 431 at the top and a collecting outlet 432 at the bottom, and the collecting inlet 431 is located below the buckle outlet 4212, so that the buckle 1 can be concentrated to the middle along the inner wall of the waste collecting member 43 during the falling process, avoiding the buckle from being scattered, and reducing the noise.

[0106] In this embodiment, in order to reduce the space and save the equipment cost, the waste receiving mechanism 40 shares the waste chute 264 and the waste collecting barrel 265 with the waste recycling unit 26 in the buckle feeding mechanism 20. In actual application, the waste chute and the waste collecting barrel in the waste recycling unit 26 and the waste chute and the waste collecting barrel in the waste receiving mechanism 40 can also be independently arranged respectively.

[0107] The collecting outlet 432 is located above the waste chute 264, and a downwardly extending guide pipe (not shown in the figure) is further arranged on the collecting outlet 432, so that the buckle 1 can smoothly fall into the waste chute 264 below, avoiding the buckle 1 from being scattered.

[0108] If the buckle detection unit 34 detects that the buckle 1 is not successfully installed on the door panel, the mechanical arm 31 carries the buckle 1 which is not successfully installed to approach the waste receiving member 42, adjusts the height to make the buckle 1 consistent with the height of the waste receiving groove 421, the bottom of the buckle 1 abuts against the top surface of the guide baffle 44, and then further moves along the guide baffle 44 to the direction of the waste receiving groove 421 under the driving of the mechanical arm 31. After the buckle 1 is buckled into the waste receiving groove 421 from the buckle inlet 4211, the mechanical arm 31 moves upward, the upper part of the buckle 1 is separated from the buckle fixing cavity, the buckle 1 stays on the waste receiving member 42 under the limiting action of the waste receiving groove 421, and moves to the buckle outlet 4212 under the pushing of the next buckled buckle 1. When the waste receiving groove 421 is full of buckles 1, the buckle 1 closest to the buckle outlet 4212 is pushed out of the waste receiving groove 421 by the subsequent buckled buckle, and then falls into the waste collecting member 43 below under the action of its own gravity, and finally slides along the waste chute 264 to the waste collecting barrel 265 for centralized storage, which is convenient for unified treatment.

[0109] Figure 16 is a flowchart of the automatic buckle installation process using the buckle automatic installation device in the embodiment of the present application, Figure 17 is a flowchart of the buckle feeding process in the embodiment of the present application. Taking the buckle installation of a predetermined installation point on the door panel as an example, the specific process of automatically installing the buckle using the buckle automatic installation device 100 of the present application will be described below in combination with the accompanying drawings. Figures 1 to 17

[0110] ​In step S1, the clip feeding mechanism 20, under the control of the clip installation control mechanism 50, provides the clip 1 to the predetermined pick-up position to complete the feeding.

[0111] In step S2, the robotic arm 31, under the control of the buckle installation control mechanism 50, drives the buckle installation component 32 to move, picks up the buckle 1 from the predetermined pick-up position and installs it onto the predetermined installation point on the door panel;

[0112] In step S3, the buckle detection unit 34 detects whether the buckle 1 is successfully installed on the door panel under the control of the buckle installation control mechanism 50. If the detection result is yes, the installation is complete; if the detection result is no, proceed to step S4.

[0113] In step S4, the buckle installation control mechanism 50 controls the robotic arm 31 to move the buckle 1 that was not successfully installed, so that the buckle 1 is transferred to the waste receiving mechanism 40 for collection.

[0114] Among them, such as Figure 16 As shown, the snap-fit ​​feeding process in step S1 specifically includes the following steps:

[0115] Step S1-1: The storage box 21 provides the buckle 1 to be installed to the vibratory feeder 22;

[0116] In steps S1-2, the snap-fit ​​installation control mechanism 50 controls the vibratory feeder 22 to output oriented snap-fits 1 to the discharge channel 23;

[0117] In steps S1-3, the buckle 1 moves along the discharge channel 23 towards the buckle moving unit 24 under the action of the vibrating plate 22;

[0118] In steps S1-4, the snap-fit ​​moving unit 24 moves the snap-fit ​​1 from the discharge channel 23 to the predetermined pick-up position under the control of the snap-fit ​​installation control mechanism 50.
