[0036] Figure 14 yes Figure 13 A magnified view of the structure within frame A. Detailed Implementation

[0037] To make the technical means, creative features, objectives and effects of the present invention easy to understand, the following embodiments, in conjunction with the accompanying drawings, will specifically illustrate the snap-fit ​​installation device of the present invention.

[0038] Figure 1 This is a schematic diagram of the snap-fit ​​installation device in an embodiment of the present invention. Figure 2 This is a front view of the snap-fit ​​mounting device in an embodiment of the present invention.

[0039] like Figure 1 , 2 As shown, the snap-fit ​​installation device 100 includes a support frame 10, a snap-fit ​​feeding mechanism 20, a snap-fit ​​installation mechanism 30, and a waste material receiving mechanism 40.

[0040] In this embodiment, the buckle is a rotating body with a locking groove at the bottom that is adapted to fit the door panel.

[0041] The support frame 10 includes a frame 11 and a support platform 12 disposed on one side of the frame 11.

[0042] Figure 3 This is a schematic diagram of the buckle feeding mechanism in an embodiment of the present invention.

[0043] like Figure 3 As shown, the snap-fit ​​feeding mechanism 20 is mounted on the support platform 12 and includes a storage box 21, a vibrating plate 22, a discharge channel 23, and a snap-fit ​​moving unit 24.

[0044] The storage bin 21 can provide clips 1 to be installed to the vibratory feeder, including the storage bin body 211 and the discharge port 212 located at the bottom of the storage bin body 211. The clips 1 stored in the storage bin body 211 through the discharge port 212 fall into the vibratory feeder 22.

[0045] The vibratory feeder 22 is positioned below the discharge port 212, enabling the snap fasteners 1 to be oriented and arranged before being output. In this embodiment, the discharge channel 23 is a straight trough, the shape of which is adapted to the snap fasteners. The outlet of the vibratory feeder 22 is connected to one end of the discharge channel 23, and the snap fasteners 1 are arranged in a row and move orderly along the discharge channel 23 to the other end under the action of the vibratory feeder 22.

[0046] Figure 4 This is a schematic diagram of the structure of the snap-fit ​​moving unit in an embodiment of the present invention. Figure 5 This is a top view of the snap-fit ​​moving unit in an embodiment of the present invention.

[0047] The latch moving unit 24 is located at the other end of the discharge channel 23, and can move the latch from the discharge channel 23 to a predetermined pick-up position. For example... Figure 4 , 5 As shown, the snap-fit ​​moving unit 24 includes an auxiliary limiting baffle 241, a snap-fit ​​receiving component 242, and a snap-fit ​​limiting component 243.

[0048] The snap-fit ​​receiving assembly 242 is capable of receiving snaps output from the outlet of the discharge channel 23, and includes a snap-fit ​​receiving plate 2421 and a receiving plate driving member 2422. The snap-fit ​​receiving plate 2421 is movably disposed at the outlet of the discharge channel 23. In this embodiment, the moving direction of the snap-fit ​​receiving plate 2421 is perpendicular to the conveying direction of the snaps in the discharge channel 23. Two mutually parallel snap-fit ​​receiving grooves 2423 are formed on the snap-fit ​​receiving plate 2421. In this embodiment, the length direction of both snap-fit ​​receiving grooves 2423 is parallel to the conveying direction of the snaps in the discharge channel 23, which facilitates the receiving of snaps output from the outlet of the discharge channel 23.

[0049] The auxiliary limiting baffle 241 is disposed on the support platform 12 along the moving direction of the snap-on receiving plate 2421. The auxiliary limiting baffle 241 is located on the side of the snap-on receiving plate 2421 near the discharge channel 23 and is perpendicular to the snap-on receiving plate 2421, and can cooperate with the snap-on receiving assembly 242 to laterally limit the snap-on in the snap-on receiving groove.

[0050] Each snap-fit ​​receiving groove 2423 includes an arc-shaped segment 2423a near the auxiliary limiting baffle 241, a straight segment 2423b extending away from the auxiliary limiting baffle 241, and a transition segment 2423c whose two ends are connected to the arc-shaped segment 2423a and the straight segment 2423b, respectively. The opening width of the arc-shaped segment 2423a near the auxiliary limiting baffle 241 is adapted to the diameter of the snap-fit, facilitating the snap-fit ​​to enter the snap-fit ​​receiving groove 2423. The end of the arc-shaped segment 2423a near the transition segment 2423c has an arc that fits against the side of the snap-fit, and the width of the transition segment 2423c is smaller than the diameter of the snap-fit, which can limit the snap-fit ​​and prevent the snap-fit ​​from entering the straight segment 2423b of the snap-fit ​​receiving groove 2423.

[0051] The receiving plate drive component 2422 is connected to the snap-on receiving plate 2421 and can drive the snap-on receiving plate 2431 to move in a direction perpendicular to the discharge channel 23. In this embodiment, the receiving plate drive component 2422 is a servo electric cylinder.

[0052] The latch limiting assembly 243 can further limit the latch on the latch receiving plate 2421, including the limiting fork plate 2431 and the fork plate drive component 2432.

[0053] 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 is adapted to the engagement groove at the bottom of the latch, and can further limit the latch in the arc segment 2423a in both the lateral and vertical directions.

[0054] There are two limiting fork plates 2431, each corresponding to one of the two snap-fit ​​receiving grooves 2423. The fork plate drive member 2432 is connected to the fork plate body 2431a of the two limiting fork plates 2431, and can drive the two limiting fork plates 2431 to move synchronously along the two snap-fit ​​receiving grooves 2423, causing the fork plate body 2431a to move along the straight section 2423b of the snap-fit ​​receiving groove 2423, thus causing the fork head 2431b to move closer to or away from the snap-fit ​​within the arc-shaped section 2423a. In this embodiment, the fork plate drive member 2432 is a cylinder.

[0055] Figure 6 This is a schematic diagram of the material feeding detection unit in an embodiment of the present invention.Figure 7 This is a top view of the feeding detection unit in an embodiment of the present invention.

[0056] like Figure 6 , 7 As shown, the latching feeding mechanism 20 also includes a feeding detection unit 25, which can detect whether the feeding is successful. The feeding detection unit 25 includes three sets of sensors 251: a first sensor 251a, a second sensor 251b, and a third sensor 251c. The first sensor 251a is used to detect whether there is a latch at the outlet of the discharge channel 23, and the second sensor 251b is used to detect whether there is a latch at the predetermined pick-up position.

[0057] 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.

[0058] A waste hopper 261 is mounted on a support platform 12. A discard pusher plate 262 is movably mounted near the upper opening of the waste hopper 261. The discard pusher plate 262 is perpendicular to the snap-fit ​​receiving plate 2421, and the bottom of the discard pusher plate 262 is higher than the upper surface of the snap-fit ​​receiving plate 2421. A pusher plate drive member 263 can drive the discard pusher plate 262 to move, so that the discard pusher plate 262 contacts the upper part of the snap-fit, thereby pushing the snap-fit ​​in the snap-fit ​​receiving groove 2423 into the waste hopper 261. In this embodiment, the pusher plate drive member 263 is a cylinder.

[0059] In this embodiment, the waste chute 264 is a U-shaped channel with its opening facing upwards. To facilitate installation and compatibility with other structures such as the support platform 12 in the snap-fit ​​installation device 100, the waste chute 264 can be composed of multiple channel segments connected end-to-end. The waste chute 264 is inclined on the support platform 12, with its upper end directly below the waste funnel 261 and its lower end above the opening of the waste collection bin 265. The snap-fit ​​mechanism in the waste funnel 261 falls into the waste chute 264 under gravity and then slides down the chute into the waste collection bin 265.

[0060] During feeding, the clips are oriented and output under the action of the vibratory feeder 22, and move along the discharge channel 23 towards the clip moving unit 24. The clip receiving plate 2421 moves under the drive of the receiving plate drive member 2422, so that the arc segment 2423a of one of the clip receiving grooves 2423 on the clip receiving plate 2421 is aligned with the outlet of the discharge channel 23. Under the action of the vibratory feeder 22, the clip moves from the outlet of the discharge channel 23 to the clip receiving groove 2423 and stops at the arc segment 2423a. The first sensor 251a senses whether there are still clips at the outlet of the discharge channel 23. If there are clips, the clips have not been successfully transferred to the clip receiving groove 2423. The vibratory feeder 22 continues to feed clips, so that the clips near the outlet of the discharge channel 23 are dislodged from the discharge channel 23 and transferred to the clip receiving groove 2423.

[0061] After one snap-fit ​​is successfully transferred to the snap-fit ​​receiving groove 2423, the receiving plate drive 2422 drives the snap-fit ​​receiving plate 2421 to move again, so that the arc-shaped segment 2423a of the other snap-fit ​​receiving groove 2423 is aligned with the outlet of the discharge channel 23 to receive the next snap-fit. After receiving two snap-fits to be installed, the receiving plate drive 2422 drives the snap-fit ​​receiving plate 2421 to move along the auxiliary limiting baffle 241, moving the two snap-fits to the predetermined pick-up position. The fork drive 2432 drives the limiting fork 2431 to move towards the snap-fit. The snap-fit ​​stops in the snap-fit ​​receiving groove 2423 under the obstruction of the auxiliary limiting baffle 241. At the same time, the fork head 2431b engages with the engaging groove at the bottom of the snap-fit, so that the snap-fit ​​is fixed in the predetermined pick-up position under the combined action of the auxiliary limiting baffle 241 and the limiting fork 2431, so that it can be picked up by the snap-fit ​​installation mechanism 30. The second sensor 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.

[0062] In this embodiment, to further improve the working efficiency of the snap-fit ​​installation station, the number of snap-fit ​​feeding mechanisms 20 and snap-fit ​​installation mechanisms 30 is set to two. The waste recycling units 26 in the two snap-fit ​​feeding mechanisms 20 share the same waste collection bin 265.

[0063] Figure 8 This is a schematic diagram of the snap-fit ​​installation mechanism in an embodiment of the present invention.

[0064] The snap-fit ​​mounting mechanism 30 is mounted on the frame 11, such as... Figure 8 As shown, the snap-fit ​​mounting mechanism 30 includes a robotic arm 31, a snap-fit ​​mounting component 32, a connecting frame 33 for the snap-fit ​​mounting component, and a snap-fit ​​detection unit 34.

[0065] The robotic arm 31 includes a robotic arm mounting base 311, a first horizontal rotation unit 312 for snap-fit ​​mounting, a second horizontal rotation unit 313 for snap-fit ​​mounting, and a lifting unit 314 for snap-fit ​​mounting.

[0066] The robotic arm mounting base 311 is installed on the upper part of the frame 11.

[0067] The first horizontal rotation unit 312 for snap-fit ​​mounting is rotatably mounted on the robotic arm mounting base 311. The first horizontal rotation unit 312 includes a first horizontal rotating arm 3121 and a first horizontal rotation drive member. The first horizontal rotation drive member is connected to the first horizontal rotating arm 3121 and can drive the first horizontal rotating arm 3121 to rotate in the horizontal direction.

[0068] The second horizontal rotating unit 313 for snap-fit ​​mounting is rotatably mounted on the first horizontal rotating unit 312 for snap-fit ​​mounting. The second horizontal rotating unit 313 for snap-fit ​​mounting includes a second horizontal rotating arm 3131 and a second horizontal rotating drive member. The second horizontal rotating arm 3131 is rotatably connected to the first horizontal rotating arm 3121, and the second horizontal rotating drive member is connected to the second horizontal rotating arm 3131, enabling the second horizontal rotating arm 3131 to rotate, thereby further expanding the range of motion of the robotic arm in the horizontal direction and facilitating processing at different points.

[0069] The snap-fit ​​mounting lifting unit 314 is mounted on the snap-fit ​​mounting second horizontal rotation unit 313 and can drive the snap-fit ​​mounting component 32 to rise and fall. In this embodiment, the snap-fit ​​mounting lifting unit 314 includes a snap-fit ​​mounting lifting motor, a snap-fit ​​mounting lifting connecting rod 3142, and a snap-fit ​​mounting lifting guide rod 3143.

[0070] The lifting motor for snap-fit ​​installation is used to drive the lifting connecting rod 3142 for snap-fit ​​installation to rise and fall.

[0071] One end of the snap-fit ​​lifting connecting rod 3142 is mounted on the second horizontal rotating arm 3131, and the other end is connected to the snap-fit ​​mounting component 32 via the snap-fit ​​mounting component connecting bracket 33.

[0072] There are two lifting guide rods 3143 for snap-fit ​​installation, both of which are parallel to the lifting connecting rod 3142 for snap-fit ​​installation. They can guide and limit the movement during lifting, which can effectively improve the stability and accuracy of the process.

[0073] The snap-fit ​​installation mechanism 30 includes at least one snap-fit ​​mounting member 32, which is mounted on the robotic arm 31 and can hold the snap-fit ​​and move under the drive of the robotic arm 31, thereby performing the picking and installation of parts.

[0074] Figure 9This is a schematic diagram of the structure of the snap-fit ​​mounting component in an embodiment of the present invention.

[0075] like Figure 9 As 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.

[0076] 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 processing efficiency.

[0077] During item retrieval, the robotic arm 31 moves to position the latch mounting members 32 above the predetermined retrieval position, with the two latch mounting members 32 aligned with the latches in the two latch receiving grooves 2423. Then, the latch mounting lifting unit 314 lowers the latch mounting members 32, causing the upper part of the latch to engage with and secure the latch fixing cavity 321. Finally, the limiting fork plate 2431 retracts, and the latch mounting lifting unit 314 raises the latch mounting members 32, lifting the latch to the predetermined lifting position.

[0078] In this embodiment, the third sensor 251c of the feeding detection unit 25 is used to detect whether there is a buckle at the predetermined lifting position. If there is no buckle at the predetermined lifting position, the feeding is unsuccessful, and the buckle in the buckle receiving groove 2423 is recycled by the waste recycling unit 26.

[0079] Figure 10 This is a schematic diagram of the buckle detection unit in an embodiment of the present invention.

[0080] like Figure 10 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.

[0081] 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. 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 controller or other higher-level equipment, and then further determine whether the snap-fit ​​is installed in place based on the magnitude of the torque.

[0082] 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.

[0083] In this embodiment, the buckle mounting point on the car door panel has a buckle mounting groove with a side opening.

[0084] 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.

[0085] During inspection, driven by the detection motor 341 for buckle installation, the drive wheel 3421 drives the driven wheel 3422 to rotate via the synchronous belt 3423, causing the buckle mounting part 32 to rotate as well, thereby applying a torsional force to the buckle. Then, based on the feedback result of the servo motor, it is determined whether the buckle is installed in place, which can effectively improve processing accuracy, reduce scrap rate, and ensure the quality of finished products.

[0086] If the buckle detection unit 34 detects that the buckle has been installed in place, the buckle installation lifting unit 314 will drive the buckle mounting part 32 to rise and separate from the buckle, thus successfully completing the buckle installation.

[0087] 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.

[0088] Figure 11 This is a schematic diagram of the waste receiving mechanism in an embodiment of the present invention. Figure 12 This is a top view of the waste receiving mechanism in an embodiment of the present invention. Figure 13 This is a front view of the waste receiving mechanism in an embodiment of the present invention. Figure 14 yes Figure 13 A magnified view of the structure within frame A.

[0089] like Figures 11-14 As 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.

[0090] 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.

[0091] like Figures 3-6As 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.

[0092] 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.

[0093] 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.

[0094] The waste collection component 43 can collect the clips 1 that detach from the clip outlet 4212 after the waste receiving tank is full. In this embodiment, the waste collection component 43 has a funnel-shaped structure that is larger at the top and smaller at the bottom. It has a collection inlet 431 at the top and a collection outlet 432 at the bottom. The collection inlet 431 is located below the clip outlet 4212, so that the clips 1 can be concentrated towards the center along the inner wall of the waste collection component 43 during the falling process, avoiding the clips from falling messily and reducing noise.

[0095] In this embodiment, to reduce space and save equipment costs, the waste receiving mechanism 40 and the waste recycling unit 26 in the snap-fit ​​feeding mechanism 20 share the waste chute 264 and the waste collection bin 265. In practical applications, the waste recycling unit 26 and the waste chute and waste collection bin of the waste receiving mechanism 40 can be set up independently.

[0096] The collection outlet 432 is located above the waste chute 264. A downward-extending guide tube (not shown in the figure) is also installed on the collection outlet 432 so that the buckle 1 can fall smoothly into the waste chute 264 below and prevent the buckle 1 from falling off.

[0097] If the buckle detection unit 34 detects that the buckle is not successfully installed, the robotic arm 31 carries the uninstalled buckle 1 close to the waste receiving component 42 and adjusts its height so that the buckle 1 is at the same height as the waste receiving groove 421. The bottom of the buckle 1 abuts against the top surface of the guide baffle 44, and then moves further along the guide baffle 44 towards the waste receiving groove 421 under the drive of the robotic arm 31. After the buckle 1 is inserted into the waste receiving groove 421 from the buckle inlet 4211, the robotic arm 31 moves upward, and the upper part of the buckle 1 separates from the buckle fixing cavity. The buckle 1 remains on the waste receiving component 42 under the limiting action of the waste receiving groove 421, and moves towards the buckle outlet 4212 under the pushing action of the next inserted buckle 1. When the waste receiving groove 421 is full of clips 1, the clip 1 closest to the clip outlet 4212 is pushed out of the waste receiving groove 421 by the subsequent clips, and then falls into the waste collection component 43 below under its own gravity. Finally, it slides down the waste chute 264 into the waste collection bucket 265 for centralized storage, which is convenient for unified treatment.

[0098] In this embodiment, the snap-fit ​​mounting device is installed in the automotive door panel assembly system. It can install the snap-fit ​​onto the door panel and, under the automatic control of the controller, cooperate with other devices in the automotive door panel assembly system to complete the overall assembly of the automotive door panel. In practical applications, the control methods of various parts of the snap-fit ​​mounting device can be appropriately modified according to environmental and cost constraints. Switches, operating handles, and other devices can be used to replace the controller in controlling some structures of the snap-fit ​​mounting device, allowing operators to manually control the switches and operating handles.

[0099] The role and effect of the embodiments

[0100] The snap-fit ​​installation device involved in this invention includes a support frame, a snap-fit ​​feeding mechanism, a snap-fit ​​installation mechanism, and a waste material receiving mechanism. These structures have the following effects:

[0101] The clip feeding mechanism is mounted on a support frame and includes a storage bin, a vibratory feeder, a discharge channel, and a clip moving unit. The storage bin provides clips to be installed to the vibratory feeder, which outputs oriented clips, allowing them to move neatly and orderly along the discharge channel and be output one by one to the clip moving unit. The clip moving unit moves the clips from the discharge channel to a predetermined pickup position for easy access by the clip installation mechanism.

[0102] The latch installation mechanism is mounted on a support frame and includes a robotic arm, a latch mounting component, and a latch detection unit. The latch mounting component, mounted on the robotic arm, stably holds the latch. The robotic arm moves the latch mounting component to pick up and install the latch. The latch detection unit, connected to the latch mounting component, detects whether the latch is correctly installed on the door panel, reducing scrap rates and improving finished product quality.

[0103] The waste receiving mechanism, mounted on the support frame, can receive unsuccessfully installed clips from the clip mounting components. Because the waste receiving components have waste receiving grooves adapted to the clips, and one end of the groove has a clip inlet for clip insertion, it can receive unsuccessfully installed clips from the robotic arm. The other end of the groove has a clip outlet for clip removal. The waste collection component collects clips that have detached after the groove is full, facilitating unified processing. The waste collection component adopts a funnel-shaped structure, wider at the bottom and narrower at the top, allowing clips to converge towards the center along the inner wall of the collection component during descent, preventing them from scattering and reducing noise. A guide baffle is located outside the clip inlet, with its top surface parallel to the waste receiving groove. It abuts against the bottom of the clip, guiding and limiting its insertion into the clip inlet. The waste receiving mechanism can receive and collect clipped waste without the need for additional motors or other components or manual assistance. It has a simple structure and low cost, which can effectively simplify operation steps, improve processing efficiency, and help realize the automation of automotive door panel production lines.

[0104] Therefore, the snap-fit ​​installation device involved in this invention can realize the installation of door panel snap-fit, avoid the operational errors and safety hazards of manual installation, reduce labor costs, and effectively improve processing efficiency and finished product quality, which helps to realize the automation of automotive door panel production lines.

[0105] The above embodiments are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
