[0046] Reference Figures 1 to 3 As shown, an embodiment of the present application discloses a side panel processing device for a vehicle, which includes an in-line production mechanism 1 and an off-line storage mechanism 2. The in-line production mechanism 1 includes a frame 11, a conveying assembly 12, a limiting assembly 13 and a docking assembly 14. The frame 11 has a buffer area 111a, a production area 112a and an empty area 113a. The conveying assembly 12 is arranged on the frame 11, and is used to drive the tooling to move between the buffer area 111a, the production area 112a and the empty area 113a. The limiting assembly 13 is arranged on the frame 11, and is used to position the tooling moved to a preset position. The docking assembly 14 is arranged at the end of the frame 11, and is used to dock with the tooling transported by the AGV cart. The off-line storage mechanism 2 is used to store multiple tooling.

[0047] In this embodiment, the tooling transported by the AGV cart includes a slide and a tooling body. The tooling body and the slide can be regarded as a whole and move synchronously. The slide is provided with a plurality of positioning holes, which are used for coordinating positioning with the conveying component 12 and the docking component 14.

[0048] In some embodiments, the tooling includes a slide, a tooling body and a gripper. A robot is provided on the production department 112. After the tooling is transported to the production department 112, the robot can be connected with the gripper. The robot can drive the gripper to move in three-dimensional space to control the gripper to grab vehicle parts onto the tooling body, thereby processing the vehicle side panel through the tooling body.

[0049] When processing the side panel of the vehicle, the tooling can be transported to the in-line production mechanism 1 by the AGV cart, and then the docking component 14 is driven to dock with the tooling, and then the tooling is driven to move to a predetermined position by the docking component 14, and then the corresponding tooling is driven to move to the preset positions of the buffer area 111a and the production area 112a by the conveying component 12, and the tooling moved to the preset position is positioned by the limit component 13, and then the side panel is processed by the tooling.

[0050] This embodiment combines "high-speed" in-line cache (cache unit) with "low-speed" large-capacity off-line storage (off-line storage mechanism), which can quickly switch the tooling corresponding to the model to be produced, improve production efficiency, and meet the requirements of small batch, multi-variety, and flexible production. At the same time, through three areas, two types of models can be switched in line at high speed, and during working hours, the tooling in the cache area 111a can be switched with the tooling offline, which will not affect the normal production of the online production area 112a, reducing non-value-added time and improving production efficiency.

[0051] Continue to refer to Figure 1 As shown, the frame 11 includes a cache section 111, a production section 112, an empty section 113, a first connecting section 114, and a second connecting section 115. The cache section 111 is provided with a cache area 111a, the production section 112 is provided with a production area 112a, and the empty section 113 is provided with an empty area 113a. The lengths of the cache section 111, the production section 112, and the second connecting section 115 are along the first direction ( Figure 1 The lengths of the first connecting portion 114 and the vacant portion 113 extend in the second direction ( Figure 1 The first connecting portion 114 is connected to the first end of the buffer portion 111 and the first end of the production portion 112 at two ends. The vacant portion 113 is connected to the second end of the production portion 112 and the second end of the second connecting portion 115 at two ends. A plurality of docking assemblies 14 are provided, and the plurality of docking assemblies 14 are respectively arranged on both sides of the second end of the buffer portion 111 and the second end of the second connecting portion 115.

[0052] In order to facilitate the transportation and positioning of the tooling, multiple conveying components 12 and limiting components 13 are provided. The multiple conveying components 12 are respectively provided in the buffer section 111, the production section 112, the empty section 113, the first connecting section 114 and the second connecting section 115. Each conveying component 12 is used to drive the tooling to move in each corresponding area. Multiple limiting components 13 are respectively provided in the buffer section 111, the production section 112 and the empty section 113. Each limiting component 13 is used to position the tooling moved to the preset position.

[0053] Also refer to Figure 2 and Figure 4As shown, each conveying assembly 12 includes a rack 121, a gear 122, a motor 123, a first positioning cylinder 124 and a moving plate 125. The rack 121 is arranged on the frame 11, the moving plate 125 is slidably connected to the frame 11, the motor 123 and the first positioning cylinder 124 are respectively arranged on the moving plate 125, the gear 122 is connected to the motor 123, and the gear 122 is also meshed with the rack 121, and the first positioning cylinder 124 is used to connect with the tooling. When driving the tooling to move, the first positioning cylinder 124 can be driven to move, so that the piston rod of the first positioning cylinder 124 extends out and passes through the positioning hole of the tooling, and then the motor 123 is started to run, so that the gear 122 rotates, thereby driving the moving plate 125 to move along the length extension direction of the rack 121, thereby driving the tooling to move.

[0054] Reference Figure 5 As shown, each limiting assembly 13 includes a plurality of first limiting cylinders 131 , which are respectively disposed on the frame 11 and are used to limit the tooling moved to a preset position.

[0055] Reference Figure 6 As shown, each docking assembly 14 includes a driving cylinder 141, a second positioning cylinder 142, a limiting roller 143 and a second limiting cylinder (not shown in the figure). The driving cylinder 141 is arranged on the frame 11, and the second positioning cylinder 142 is connected to the driving cylinder 141. There are multiple limiting rollers 143, and the multiple limiting rollers 143 are arranged on both sides of the end of the frame 11 along the first direction to guide the moving direction of the tooling 100. The second limiting cylinder is arranged on the frame 11 to limit the tooling. Through the arrangement of the docking assembly 14, this embodiment can guide and fix the tooling 100 to a precise predetermined position.

[0056] Reference Figure 7 As shown, in this embodiment, the off-line storage mechanism 2 is provided with a plurality of storage locations 21, which are arranged in an array to store a plurality of tooling. For example, one row may be for tooling for processing the left side, and the other row may be for tooling for processing the right side.

[0057] In actual application scenarios, during the process of loading the buffer portion 111, the tooling 100 ( Figure 5The second positioning cylinder 142 is driven by the second positioning cylinder 142 to extend its piston rod so as to extend the piston rod of the second positioning cylinder 142 so as to extend the piston rod of the second positioning cylinder 142 into the positioning hole of the tooling 100 and engage with the tooling 100. The cylinder 141 is then driven to drive its piston rod to retract so as to drive the tooling 100 to move toward the direction close to the buffer portion 111 and move the tooling 100 to the predetermined position. The piston rod of the second positioning cylinder 142 is then driven to retract so as to disengage the piston rod of the second positioning cylinder 142 from the positioning hole of the tooling.

[0058] In the process of driving the tooling to move on the buffer section 111, the tooling can be transported to the preset position of the buffer area 111a by the conveying assembly 12 provided in the buffer section 111. The specific conveying process is as follows: the piston rod of the first positioning cylinder 124 can be driven to extend, so that the piston rod of the first positioning cylinder 124 extends into the positioning hole of the tooling 100 and engages with the tooling, and then the motor 123 is controlled to operate to rotate the gear 122. In the process of the gear 122 and the rack 121 meshing and operating, the moving plate 125 will be driven to move along the length extension direction of the rack 121, thereby driving the tooling to move on the buffer section 111. It should be noted that the movement of the tooling on the production section 112, the vacant section 113, the first connecting section 114 and the second connecting section 115 is similar to the movement of the tooling on the buffer section 111, which will not be repeated here.

[0059] In the process of unloading the vacant part 113, the tooling can be transported to one end of the vacant part 113 close to the second connecting part 115 by the conveying assembly 12 arranged at the vacant part 113, and then the tooling can be transported to a predetermined position of the second connecting part 115 by the conveying assembly 12 arranged at the second connecting part 115; then, the tooling can be transported to the AGV trolley located at the second end of the second connecting part 115 by the conveying assembly 12 arranged at the second end of the second connecting part 115, and then the tooling can be transported away by the AGV trolley. The specific transportation process is as follows: The second positioning cylinder 142 drives its piston rod to extend, so that the piston rod of the second positioning cylinder 142 extends into the positioning hole of the tooling 100 and engages with the tooling 100. Then, the driving cylinder 141 drives its piston rod to extend, so as to drive the tooling 100 to move away from the second connecting portion 115, so that the tooling 100 moves to the AGV cart, and then the piston rod of the second positioning cylinder 142 is driven to retract, so that the piston rod of the second positioning cylinder 142 is separated from the positioning hole of the tooling, and then the tooling can be transported away by the AGV cart.

[0060] The technical effects that can be achieved by this application are: fully intelligent scheduling of production tooling, accurate and efficient tooling switching, intelligent and efficient tooling path trajectory planning, improving overall production efficiency, and reducing production conflicts. At the same time, the overall switching of tooling not only improves efficiency, reduces the mutual interference problem when switching various tooling, but also reduces the number of robots used to switch tooling, improving robot efficiency.

[0061] Reference Figure 8 As shown, accordingly, an embodiment of the present application further discloses a vehicle side panel processing method, which is applied to the side panel processing device described in any of the above embodiments. Specifically, the side panel processing method includes:

[0062] S11. Deliver tooling that matches the first batch of models to be produced to the production area.

[0063] Specifically, the tooling matching the first batch of vehicle models to be produced can be transported to the second end of the cache section 111 by the AGV cart and docked with the docking assembly 14. The tooling is transported to a predetermined position by the docking assembly 14, and then transported to the cache section 111 by the conveying assembly 12 provided in the cache section 111. Thereafter, the tooling is transported to the first connecting section 114 by the conveying assembly 12 provided in the first connecting section 114, and then transported to a preset position of the production section 112 by the conveying assembly 12 provided in the production section 112, and the tooling is positioned by the limit assembly 13.

[0064] S12. Transport tooling that matches the second batch of models to be produced to the cache area.

[0065] Specifically, the tooling matching the second batch of vehicle models to be produced can be transported to the second end of the cache section 111 by the AGV cart and docked with the docking assembly 14. The docking assembly 14 can be used to transport the tooling to a predetermined position, and then the conveying assembly 12 provided in the cache section 111 can be used to transport the tooling to a preset position in the cache section 111, and the tooling can be positioned by the limit assembly 13.

[0066] S13. Use the tooling currently located in the production area to process the side panels of the first batch of models to be produced, and obtain the current n batches of models to be produced.

[0067] Specifically, the current batch of production models refers to the production models currently being processed, and the current n batches of production models refer to the production models from the currently processed production models to the nth batch in order. The value of n can be greater than or equal to 3, for example, the value of n can be 3, 5, etc. In this embodiment, the value of n can be 4. If the number of batches is less than n, all batches of production models are obtained.

[0068] Exemplarily, if the number of batches of vehicle models to be processed is 8 and the value of n is 4, the current 4 batches of vehicle models to be produced obtained for the first time are the first to fourth batches of vehicle models to be produced, the current 4 batches of vehicle models to be produced obtained for the second time are the second to fifth batches of vehicle models to be produced, the current 4 batches of vehicle models to be produced obtained for the third time are the third to sixth batches of vehicle models to be produced, the current 4 batches of vehicle models to be produced obtained for the fourth time are the fourth to seventh batches of vehicle models to be produced, and the current 4 batches of vehicle models to be produced obtained for the fifth time are the fifth to eighth batches of vehicle models to be produced; the current 4 batches of vehicle models to be produced obtained for the sixth time are the sixth to eighth batches of vehicle models to be produced, and the current 4 batches of vehicle models to be produced obtained for the seventh time are the seventh to eighth batches of vehicle models to be produced.

[0069] S14. After the first batch of side panels of the production vehicle models are processed, the tooling information currently located in the production area is obtained.

[0070] S17, determining whether the second batch of models to be produced matches the tooling information currently located in the production area.

[0071] S18. When it is determined that the second batch of models to be produced does not match the tooling information currently located in the production area, the tooling currently located in the production area is switched, and the side panels of the second batch of models to be produced are processed using the tooling located in the production area after switching.

[0072] Specifically, when it is determined that the second batch of models to be produced does not match the tooling information currently located in the production area 112a, the tooling information currently located in the cache area 111a is obtained, and it is determined whether the tooling information currently located in the cache area 111a matches the second batch of models to be produced. When it is determined that the tooling information currently located in the cache area 111a matches the second batch of models to be produced, the tooling currently located in the production area 112a is transferred to the vacant area 113a, and then the tooling currently located in the cache area 111a is transferred to the production area 112a; when it is determined that the tooling information currently located in the cache area 111a does not match the second batch of models to be produced, the tooling currently located in the cache area 111a is removed, the tooling currently located in the production area 112a is transferred to the cache area 111a, the tooling that matches the second batch of models to be produced is transferred to the vacant area 113a, and then transferred from the vacant area 113a to the production area 112a.

[0073] S19. When it is determined that the second batch of models to be produced matches the tooling information currently located in the production area, the tooling currently located in the production area is used to process the side panels of the second batch of models to be produced.

[0074] When processing the side panels of each batch of models to be processed, although the processing order of each batch of models to be produced will be arranged in advance, the processing order of each batch of models to be produced may be disrupted due to certain circumstances. Therefore, before processing the side panels of the second batch of models to be produced, it is necessary to first confirm the tooling that matches the second batch of models to be produced.

[0075] In some embodiments, after obtaining the current n batches of vehicle models to be produced, if n≥3, the tooling matching the third batch to the nth batch of vehicle models to be produced can be transported from the off-line storage mechanism 2 to the waiting area by the AGV cart, ready to be transported to the on-line production mechanism 1.

[0076] In some embodiments, after the tooling currently located in the production area 112a is transferred to the vacant area 113a, it is confirmed whether the tooling currently located in the vacant area 113a matches the third batch of models to be produced. If it is determined that the tooling currently located in the vacant area 113a does not match the third batch of models to be produced, the tooling currently located in the vacant area 113a is moved out of the vacant area 113a. If it is determined that the tooling currently located in the vacant area 113a matches the third batch of models to be produced, it is not transported away. When the third batch of models to be produced are processed, the tooling currently located in the vacant area 113a is moved to the production area 112a. That is, the roles of the vacant area 113a and the buffer area 112a can be interchanged, one of which can be used to place the tooling to be used, and the other is used to facilitate the transportation of the tooling located in the production area 112a.

[0077] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
