Description

Technical Field

[0001] This invention relates to the technical field of vehicle rear wheel arch edging devices, specifically to a vehicle wheel arch edging system and its usage method. Background Technology

[0002] With the rapid iteration of automobiles, more and more car rear wheel arches are adopting edge-sealing processes, leading to the increasingly widespread application of robotic online edge-sealing technology. Currently, OEMs typically use robotic edge-sealing at the side panel assembly station. The tire film is fixed or replaced onto a fixture, then clamped by a clamping mechanism to secure the film to the side panel assembly, and the robot performs the edge-sealing. However, side panel assembly edge-sealing requires a separate station, consuming a large area. On multi-model production lines, when some models' rear wheel arches are not edge-sealed, the utilization rate of the side panel assembly edge-sealing station is low, increasing the logistics route for these un-edged models.

[0003] Existing technology 1 provides a rear wheel arch hemming device for automobiles. The rear wheel arch hemming liner is placed on a liner positioning slide. After the liner is locked by a positioning clamping mechanism on the slide, the slide slides together with the liner until it is in contact with the vehicle body's hemming position, and then a robot performs the hemming. The drawbacks of this existing technology are: the slide occupies a large area, leading to a shortage of storage space for liners of multiple vehicle models; it requires two additional slide mechanisms and their associated clamping mechanisms, increasing cost and failure rate; the robot must first grasp the liner and attach it to the slide, and then wait for the slide to slide into contact with the vehicle body before proceeding to the next hemming operation, increasing processing time.

[0004] Existing technology two provides a rear wheel arch hemming system and its working method for a white body. Multiple rear wheel arch hemming films for various car models are simultaneously installed at the end of a transport robot. Before hemming, the required film is placed on a support platform, and then a cylinder on the support platform pushes the film to slide until it adheres to the hemming position on the car body. The robot then performs the hemming. The existing technical problems are: the gripping part at the end of the transport robot is complex and has a high failure rate; it requires additional transport robots and support platforms, increasing the footprint and cost; and the film only adheres to the support platform at the bottom, easily causing the upper hemming surface to not adhere properly. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this invention is to provide a vehicle wheel arch hemming system and its usage method, so as to solve the problem that the rear wheel arch hemming film needs to be placed on a slide table, resulting in a large footprint and inconvenient processing.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0016] Multiple adsorption elements are arranged at circumferential intervals along the above-mentioned rolled edge tire film body for adsorption onto the surface of the rear wheel cover outer panel. The adsorption elements are electrically connected to the output end of the above-mentioned fixed electrical interface.

[0017] In some optional embodiments, the above-mentioned sheathing membrane mechanism further includes an interface fixing plate fixedly connected to the sheathing membrane body.

[0020] In some optional embodiments, the interface fixing plate is further provided with a positioning detection block for detecting whether the input end of the fixed electrical interface is properly connected to the output end of the electrical adapter.

[0021] In some optional embodiments, the conversion locking assembly includes a lower guide pin and a second safety locking pin, and the aforementioned transport insertion locking assembly includes:

[0024] In some optional embodiments, the above-mentioned rolled edge membrane body is provided with a plurality of positioning plates, the positioning plates are provided with positioning holes, and the above-mentioned rolled edge membrane support assembly includes a plurality of positioning pins that correspond one-to-one with the above-mentioned positioning holes and are inserted into each other.

[0025] On the other hand, this application also provides a method of using a vehicle wheel arch hemming system, implemented using any of the above-mentioned vehicle wheel arch hemming systems, including the following steps:

[0026] The hemming transport mechanism supports the hemming film mechanism to move to the processing position and connects the clamping and adsorption components on the hemming film mechanism to the surface of the rear wheel cover outer plate.

[0027] The aforementioned hemming and moving mechanism is disengaged from the aforementioned hemming and liner mechanism, and the aforementioned hemming and moving mechanism cooperates with the hemming and liner body to hem the outer panel of the rear wheel arch.

[0028] In some optional embodiments, the hemming transfer mechanism supports the hemming film mechanism to the processing position and connects the clamping and adsorption assembly on the hemming film mechanism to the surface of the rear wheel arch outer panel, including:

[0030] Compared with the prior art, the advantages of the present invention are as follows: by setting a clamping and adsorption component on the rolling edge tire film mechanism, and by moving the rolling edge tire film mechanism to the processing position and attaching it to the surface of the rear wheel cover outer plate, the slide table and support table are eliminated, effectively reducing the floor space occupied by the workstation, and the processing process is more convenient. Different models of rolling edge tire film mechanisms can be stored in a storage rack, and the rolling edge tire film mechanism with the corresponding signal can be selected according to the vehicle model requirements, thereby improving processing efficiency.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] On the one hand, such as Figure 1 As shown, this application provides a vehicle wheel arch hemming system, including a hemming film mechanism 1 and a hemming transport mechanism 2. The hemming transport mechanism 2 is used to transport the hemming film mechanism 1 to the processing position. After the hemming film mechanism 1 is transported to the processing position, it is attached to the surface of the rear wheel arch outer panel. Then, the hemming transport mechanism 2 separates from the hemming film mechanism 1 and begins to hem the rear wheel arch outer panel along the arc contour of the hemming film mechanism 1.

[0044] Specifically, such as Figure 2 and Figure 5 As shown, the hemming liner mechanism 1 includes a hemming liner body 11 and a clamping and adsorption assembly 12 connected to the hemming liner body 11. The clamping and adsorption assembly 12 is used to connect with the surface of the rear wheel cover outer panel. The hemming transport mechanism 2 includes a hemming liner support assembly 21 and a hemming wheel 22. The hemming liner support assembly 21 is used to support the hemming liner mechanism 1 to move to the processing position so that the clamping and adsorption assembly 12 connects with the surface of the rear wheel cover outer panel. The hemming wheel 22 cooperates with the hemming liner body 11 to hem the rear wheel cover outer panel.

[0045] It is understood that the hemming transport mechanism 2 can be connected to the hemming film mechanism 1 as a whole, so that the hemming transport mechanism 2 can be moved to the processing position; or it can be separated from the hemming film mechanism 1, so that the hemming film body 11 is kept connected to the surface of the rear wheel cover by the clamping adsorption assembly 12, while the hemming wheel 22 of the hemming transport mechanism 2 hemms the rear wheel cover along the arc contour of the hemming film body 11.

[0046] Compared to existing technologies, the edging film mechanism 1 requires a slide table and support platform to maintain its relative position with the rear wheel arch outer panel. The clamping and adsorption assembly 12 then connects the edging film body 11 to the surface of the rear wheel arch outer panel, eliminating the need for the slide table and support platform, thus effectively reducing the workstation's footprint. Furthermore, the edging film mechanism 1 can be moved to or from the processing position by the edging transport mechanism 2, making the processing more convenient. For different vehicle models, the edging film mechanism 1 can be supported by the corresponding edging film mechanism 1, enabling switching between edging for different models, improving processing efficiency, and saving time.

[0047] In some alternative embodiments, such as Figure 7 As shown, the above-mentioned vehicle wheel arch hemming system also includes a conversion interface 3. The above-mentioned hemming liner mechanism 1 is provided with a fixed electrical interface 13 that is electrically connected to the clamping and adsorption assembly 12. The above-mentioned hemming moving mechanism 2 is provided with a moving insertion locking assembly 23. When the above-mentioned hemming liner support assembly 21 is used to support the hemming liner mechanism 1 to move to the processing position, the above-mentioned conversion interface 3 is locked on the above-mentioned moving insertion locking assembly 23. When the above-mentioned clamping and adsorption assembly 12 is connected to the surface of the rear wheel arch outer plate, the above-mentioned conversion interface 3 is electrically connected to the fixed electrical interface 13 and disengaged from the above-mentioned moving insertion locking assembly 23.

[0048] In other words, the clamping and adsorption assembly 12 needs to be connected to the control circuit to provide the clamping and adsorption power for the clamping and adsorption assembly 12, thereby achieving connection and separation with the surface of the rear wheel arch outer panel. In order to facilitate the adaptation of the hemming film mechanism 1 and the hemming transport mechanism 2 of different vehicle models, and to share a control circuit to reduce wiring layout, a conversion interface 3 is set, and the same fixed electrical interface 13 adapted to the conversion interface 3 is set on different models of hemming film mechanism 1, so that the hemming transport mechanism 2 can be connected to different models of hemming film mechanism 1 through the conversion interface 3, so that the conversion interface 3 and the hemming film mechanism 1 can be transported together to the processing position.

[0049] In some optional embodiments, the conversion interface 3 includes an electrical conversion interface 31 and a conversion locking component 32. The output end of the electrical conversion interface 31 is electrically connected to the fixed electrical interface 13, and its input end is connected to the control circuit to provide power to the clamping and adsorption component 12. The conversion locking component 32 is locked to the moving insertion locking component 23, and disengages from the moving insertion locking component 23 after the clamping and adsorption component 12 is connected to the surface of the rear wheel cover outer plate.

[0050] In some optional embodiments, the clamping and adsorption assembly 12 includes a plurality of clamping members 121 and a plurality of adsorption members 122. The plurality of clamping members 121 are arranged circumferentially spaced along the tire membrane body 11 and are used to clamp the rear wheel cover outer plate. The clamping members 121 are electrically connected to the output end of the fixed electrical interface 13. The plurality of adsorption members 122 are arranged circumferentially spaced along the tire membrane body 11 and are used to adsorb onto the surface of the rear wheel cover outer plate. The adsorption members 122 are electrically connected to the output end of the fixed electrical interface 13.

[0051] It is understood that the rolled edge liner body 11 is an arc shape that matches the size of the rear wheel cover after the rolled edge is formed. In order to facilitate the connection between the rolled edge liner body 11 and the outer plate of the rear wheel cover and ensure the stability of the connection, the connection is carried out by two methods: adsorption and clamping.

[0052] Optionally, the adsorption component 122 includes a suction cup with elastic deformation, and the clamping component 121 includes an openable and closable gripper. Both need to be electrically connected to the conversion interface 3 through the fixed electrical interface 13, thereby connecting to the control circuit to provide an air source for the suction cup to adsorb or detach from the surface of the rear wheel cover, and to provide the clamping force to open and close to clamp or release the rear wheel cover.

[0053] The number and arrangement of the adsorption member 122 and the clamping member 121 can be specifically set according to the shape of the rear wheel cover outer plate. In this embodiment, it is an optional arrangement, but it is not limited to this implementation.

[0054] In some alternative embodiments, such as Figure 4 As shown, the aforementioned edge-rolling membrane mechanism 1 further includes an interface fixing plate 14 fixedly connected to the edge-rolling membrane body 11. The aforementioned fixed electrical interface 13 is disposed on the aforementioned interface fixing plate 14. The aforementioned interface fixing plate 14 is provided with an interface guide pin hole 141 and a first safety lock pin 142. The aforementioned conversion interface 3 further includes an upper guide pin 34 and a first safety lock 33. The upper guide pin 34 is inserted into the aforementioned guide pin hole 141; the first safety lock 33 is locked into the aforementioned first safety lock pin 142.

[0055] It is understandable that, in order to ensure that when the rolled liner body 11 is connected to the surface of the rear wheel arch outer panel via the clamping and adsorption assembly 12, the conversion interface 3 can maintain the connection between the clamping and adsorption assembly 12 and the control circuit, preventing disconnection and connection failure that would affect the rolling wheel 22's rolling of the rear wheel arch outer panel, a first safety locking pin 142 and a first safety lock 33 are provided for locking and connecting, so that the conversion interface 3 maintains an electrical connection with the fixed electrical interface 13. The function of the guide pin hole 141 and the upper guide pin 34 is to provide guidance for the locking and connection of the first safety locking pin 142 and the first safety lock 33.

[0056] In this example, a fixed electrical interface conversion interface 15 is also provided on the interface fixing plate 14. The fixed electrical interface conversion interface 15 can be regarded as the input terminal of the fixed electrical interface 13, and the fixed electrical interface conversion interface 15 is used for electrical connection with the output terminal of the electrical adapter interface 31. Therefore, the guide pin hole 141 and the upper guide pin 34 also provide positioning and guidance for the output terminals of the fixed electrical interface conversion interface 15 and the electrical adapter interface 31.

[0057] In some optional embodiments, the interface fixing plate 14 is further provided with a positioning detection block 143 for detecting whether the input end of the fixed electrical interface 13 is connected to the output end of the electrical adapter 31.

[0058] Optionally, the position detection block 143 is signal-connected to the first safety lock 33. When the position detection block 143 detects that the input end of the fixed electrical interface 13 is connected to the output end of the aforementioned electrical adapter 31, the first safety lock 33 is locked to the first safety lock pin 142.

[0059] In some alternative embodiments, such as Figure 5 and Figure 6 As shown, the conversion interface 3 is also provided with a lower guide pin 321 and a second safety lock pin 322. The moving insertion locking component 23 includes a moving insertion guide pin hole 231 and a second safety lock 232. The moving insertion guide pin hole 231 is inserted into the lower guide pin 321; the second safety lock 232 is locked to the second safety lock pin 322.

[0060] Understandably, the function of the second safety lock pin 322 and the second safety lock 232 is to ensure the stability of the connection between the conversion interface 3 and the hemming transport mechanism 2. The transport insertion guide pin hole 231 engages with the aforementioned lower guide pin 321, thereby providing guidance for the locking connection of the second safety lock pin 322 and the second safety lock 232. When the hemming membrane support assembly 21 supports the hemming membrane mechanism 1 and moves it to the processing position so that the clamping adsorption assembly 12 is connected to the surface of the rear wheel arch outer plate, in order to ensure that the hemming membrane mechanism 1 will not fall off the hemming transport mechanism 2 during the movement, in conjunction with the connection between the hemming membrane support assembly 21 and the hemming membrane mechanism 1, the transport insertion locking assembly 23 is locked to the conversion interface 3, and the conversion interface 3 is locked to the hemming membrane mechanism 1. After the clamping adsorption assembly 12 is connected to the surface of the rear wheel arch outer plate, the second safety lock pin 322 and the second safety lock 232 are unlocked, causing the conversion interface 3 to disengage from the hemming transport mechanism 2.

[0061] In some optional embodiments, the above-mentioned rolled edge membrane body 11 is provided with a plurality of positioning plates 111, the positioning plates 111 are provided with positioning holes 112, and the above-mentioned rolled edge membrane support assembly 21 includes a plurality of positioning pins 211 that correspond one-to-one with the above-mentioned positioning holes 112 and are inserted into each other.

[0062] It is understandable that the rolling edge transport mechanism 2 can support the rolling edge film mechanism 1 to move to the processing position through the insertion and cooperation of multiple positioning pins 211 and positioning holes 112.

[0063] In this example, since there are three positioning plates 111, located at the radial ends of the arc-shaped edging film body 11 and between the radial ends, there are corresponding three positioning pins 211, which are connected to the bracket body 20 of the edging transport mechanism 2 through the support rod 25, so that when the positioning pins 211 are inserted into the positioning holes 112, the support rod 25 can support the positioning plates 111.

[0064] Of course, in other embodiments, the connection between the hemming membrane mechanism 1 and the hemming transport mechanism 2 can also be achieved through other methods, such as snap-fit ​​and slot. However, the insertion and connection method using pins and holes is more convenient. When the two need to be connected, the hemming transport mechanism 2 can be lifted from below to the hemming membrane mechanism 1; when the two need to be separated, the hemming transport mechanism 2 can be moved downward relative to the hemming membrane mechanism 1. At the same time, when the hemming transport mechanism 2 is adapted to different models of hemming membrane mechanisms 1, only positioning holes need to be made at the corresponding positions on the hemming membrane mechanism 1, without making too many structural modifications, thus reducing costs. On the other hand, in this application, the conversion interface 3 and the transport plug-in locking component 23, as well as the conversion interface 3 and the interface fixing plate 14, are all connected by the plug-in engagement of guide pins and guide pin holes. Therefore, in order to achieve the rapid engagement and rapid separation of the rolling edge film mechanism 1 and the rolling edge transport mechanism 2, the connection and engagement between the rolling edge film mechanism 1, the rolling edge transport mechanism 2 and the conversion interface 3 are all done by plugging in, and the plugging and engagement actions are all completed from bottom to top and from top to bottom.

[0065] In this example, the positioning pin 211, the transport and locking assembly 23, and the roller 22 are all connected to the bracket body 20. Meanwhile, on the other side of the bracket body 20 away from the roller 22, there is also a flange 24 for connection to a robotic arm or robot.

[0066] On the other hand, this application also provides a method of using a vehicle wheel arch hemming system, implemented using any of the above-mentioned vehicle wheel arch hemming systems, including the following steps:

[0067] S1: The rolling edge transport mechanism 2 supports the rolling edge film mechanism 1 to move to the processing position and connects the clamping and adsorption assembly 12 on the rolling edge film mechanism 1 to the surface of the rear wheel cover outer plate.

[0068] In some optional embodiments, the above-mentioned vehicle wheel cover hemming system further includes a conversion interface 3, the above-mentioned hemming film mechanism 1 is provided with a fixed electrical interface 13 that is electrically connected to the clamping and adsorption assembly 12, and the above-mentioned hemming transport mechanism 2 is provided with a transport plug-in locking assembly 23.

[0069] When the hemming transfer mechanism 2 supports the hemming film mechanism 1 to move to the processing position, the conversion interface 3 is locked on the transfer plug-in locking assembly 23. The conversion interface 3 is electrically connected to the fixed electrical interface 13 so that the clamping adsorption assembly 12 is connected to the surface of the rear wheel cover outer plate.

[0070] In other words, the clamping and adsorption assembly 12 needs to be connected to the control circuit to provide the clamping and adsorption power for the clamping and adsorption assembly 12, so as to realize the connection and separation with the surface of the rear wheel cover.

[0071] In some optional embodiments, the conversion interface 3 includes an electrical adapter 31 and a conversion locking component 32. The output end of the electrical adapter 31 is electrically connected to the fixed electrical interface 13, and its input end is connected to the control circuit to provide power to the clamping and adsorption component 12.

[0072] S2: The above-mentioned rolling edge transport mechanism 2 is disengaged from the above-mentioned rolling edge film mechanism 1, and the above-mentioned rolling edge transport mechanism 2 cooperates with the above-mentioned rolling edge film body 11 to roll the edge of the rear wheel cover outer panel.

[0073] It is understood that when the clamping and adsorption assembly 12 is connected to the rear wheel arch outer plate, the relative position between the hemmed liner body 11 and the rear wheel arch outer plate is fixed, and hemming can then begin. The aforementioned conversion interface 3 maintains its electrical connection with the fixed electrical interface 13, and the aforementioned conversion interface 3 is disengaged from the aforementioned transport plug-in locking assembly 23. After disengagement, the hemming transport mechanism 2, through the hemming wheel 22, hemms the rear wheel arch outer plate along the arcuate contour of the hemmed liner body 11.

[0074] To ensure that the edging liner body 11 is connected to the surface of the rear wheel arch outer panel via the clamping and adsorption assembly 12, the conversion interface 3 maintains the connection between the clamping and adsorption assembly 12 and the control circuit, preventing disconnection and connection failure that could affect the edging wheel 22's edging of the rear wheel arch outer panel. In some optional embodiments, the edging liner mechanism 1 further includes an interface fixing plate 14 fixedly connected to the edging liner body 11. The fixed electrical interface 13 is disposed on the interface fixing plate 14, which has an interface guide pin hole 141 and a first safety lock pin 142. The conversion interface 3 also includes an upper guide pin 34 and a first safety lock 33. The upper guide pin 34 engages with the guide pin hole 141; the first safety lock 33 locks with the first safety lock pin 142.

[0075] In other words, when the conversion interface 3 is electrically connected to the fixed electrical interface 13, the upper guide pin 34 is inserted into the guide pin hole 141; the first safety lock 33 is locked into the first safety lock pin 142.

[0076] In some optional embodiments, before the hemming transfer mechanism 2 supports the hemming film mechanism 1 to move to the processing position, it is also necessary to select the appropriate model of the hemming film mechanism 1 for different vehicle models.

[0077] Specifically, after the hemming processing position receives the vehicle model information of the model to be produced, the hemming robot moves from the origin to the storage rack of the hemming film mechanism 1 for the corresponding model. Then, multiple positioning pins 211 and positioning holes 112 are inserted and engaged, the conversion interface 3 is electrically connected to the fixed electrical interface 13, the upper guide pin 34 is inserted and engaged with the guide pin hole 141, the first safety lock 33 is locked and connected with the first safety lock pin 142, and the hemming film mechanism 1 and the hemming transport mechanism 2 are connected to form the whole vehicle wheel cover hemming system. The hemming robot can carry the vehicle wheel cover hemming system away from the storage rack of the hemming film mechanism and move to the hemming processing position.

[0078] This invention discloses a vehicle wheel arch hemming system and its usage method. By installing a clamping and adsorption assembly 12 on the hemming film mechanism 1, and moving the hemming film mechanism 1 to the processing position for bonding with the surface of the rear wheel arch outer panel, the system eliminates the need for slides and support tables, effectively reducing the floor space required at the workstation and making the processing more convenient. Different models of the hemming film mechanism 1 can be stored centrally in a storage rack, and the appropriate signal hemming film mechanism 1 can be selected according to the vehicle model requirements, improving processing efficiency. A conversion interface 3 facilitates the adaptation of hemming film mechanisms 1 for different vehicle models to the hemming transport mechanism 2, and a shared control circuit reduces wiring layout. Multiple clamping components 121 and multiple adsorption components 122 ensure the stability and compatibility of the connection with the rear wheel arch outer panel. A first safety lock pin 142 and a first safety lock 33 are provided for locking and connecting. The system ensures that the conversion interface 3 and the fixed electrical interface 13 are electrically connected, and that the clamping and adsorption assembly 12 is connected to the control circuit, preventing detachment and connection failure. The placement detection block 143 improves the reliability of the connection between the conversion interface 3 and the rolling edge membrane mechanism 1. To ensure that the rolling edge membrane mechanism 1 does not detach from the rolling edge transport mechanism 2 during movement, the transport insertion locking assembly 23 is locked to the conversion interface 3 in conjunction with the connection between the rolling edge membrane support assembly 21 and the rolling edge membrane mechanism 1. The connection between the rolling edge membrane mechanism 1, the rolling edge transport mechanism 2, and the conversion interface 3 all uses a plug-in method, with the plug-in action performed from bottom to top and from top to bottom, thus achieving rapid engagement and disengagement of the rolling edge membrane mechanism 1 and the rolling edge transport mechanism 2.

[0079] In the description of this application, it should be noted that the terms "upper," "lower," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
