[0038] This utility model proposes an assembly device 100 for assembling the vehicle floor and the front pillar outer panel 200.

[0039] Please see Figure 1 In one embodiment of this utility model, the assembly equipment 100 includes a transport device 1, an assembly device 2, and a transfer device 3. The two ends of the transport device 1 are a loading end 11 and a unloading end 12, respectively. The transport device 1 is used to transport the front pillar outer panel 200 loaded to the loading end 11 to the unloading end 12. The front pillar outer panel 200 includes a left front pillar outer panel and a right front pillar outer panel. The assembly device 2 includes a workbench 22 and two assembly robots 21. The workbench 22 is located near the unloading end 12 and is used to place the vehicle body floor. The two assembly robots 21 are the first assembly robot 21 and the second assembly robot 22. 1a and 21b are respectively arranged on both sides of the workbench 22; the transfer device 3 includes a transfer robot 31, a transfer platform 32 and an overhead platform 23. The transfer robot 31 is arranged close to the unloading end 12, and the transfer platform 32 is located between the workbench 22 and the unloading end 12. The transfer robot 31 is used to transfer the front pillar outer panel 200 transported to the unloading end 12 to the transfer platform 32. The assembly robot 21 is used to assemble the front pillar outer panel 200 transferred to the transfer platform 32 and place it on the vehicle floor of the workbench 22.

[0040] The first assembly robot 21a is used to place the outer panel of the left front pillar located on the transfer platform 32 onto the overhead platform 23, and is also used to assemble the outer panel of the right front pillar on the transfer platform 32 onto the vehicle body floor placed on the workbench 22. The second assembly robot 21b is used to assemble the outer panel of the left front pillar on the overhead platform 23 onto the vehicle body floor placed on the workbench 22.

[0041] The assembly equipment 100 of this utility model uses a transport device 1 to transport the front pillar outer panel 200. After the front pillar outer panel 200 is loaded onto the transport device 1 at the loading end 11, it is automatically transported to the unloading end 12 by the transport device 1. A transfer device 3 is set up, which includes a transfer robot 31 and a transfer platform 32. The transfer robot 31 can automatically transfer the front pillar outer panel 200 transported to the unloading end 12 to the transfer platform 32. The assembly device 2 includes a workbench 22 and an assembly robot 21. The workbench 22 is used to place the vehicle floor. The assembly robot 21 assembles the front pillar outer panel 200 on the transfer platform 32 onto the vehicle floor, realizing automated assembly. Compared to the manual and semi-automatic methods in the prior art, the assembly equipment 100 of this utility model completes the transportation, handling and assembly of the front pillar outer panel 200 through the transportation device 1, the transfer device 3 and the assembly device 2 respectively, without relying on manual assistance, reducing the demand for manpower and thus reducing the intensity of manual labor. Furthermore, the automated transfer and splicing improve the assembly efficiency of the front pillar outer panel 200 and the vehicle floor, reducing the risk of damage to the front pillar outer panel 200 and other components due to human error, making it safer and more reliable.

[0042] Furthermore, by setting up two assembly robots 21 and an overhead platform 23, the first assembly robot 21a can not only transfer the left front pillar outer panel 200 located on the intermediate platform 32 to the overhead platform 23, but also assemble the right front pillar outer panel 200 located on the intermediate platform 32 onto the vehicle body floor placed on the workbench 22; the second assembly robot 21b is used to assemble the left front pillar outer panel 200 on the overhead platform 23 onto the vehicle body floor placed on the workbench 22. By assembling the two front pillar outer panels 200 onto the two sides of the same vehicle body floor by the two assembly robots 21, the manufacturing cycle of a single vehicle is shortened and the overall vehicle production efficiency is improved.

[0043] Understandably, both sides of the vehicle floor need to be assembled with front pillar outer panels 200. The front pillar outer panels 200 on both sides of the vehicle floor can be regarded as the left front pillar outer panel 200 and the right front pillar outer panel 200, respectively. The left front pillar outer panel 200 and the right front pillar outer panel 200 are transported by the aforementioned transport device 1 and transferred by the transfer robot 31. Any assembly robot 21 is used to assemble the left front pillar outer panel 200 or the right front pillar outer panel 200 onto the vehicle floor.

[0044] In this embodiment, the first assembly robot 21a is used to assemble the left front pillar outer panel 200 onto the vehicle floor, and the second assembly robot 21b is used to assemble the right front pillar outer panel 200 onto the vehicle floor. When the transfer robot 31 transfers the left and right front pillar outer panels 200 onto the transfer platform 32, the first assembly robot 21a directly transfers the left front pillar outer panel 200 onto the overhead platform 23, and then assembles the right front pillar outer panel 200 onto the vehicle floor; the second assembly robot 21b assembles the left front pillar outer panel 200 from the overhead platform 23 onto the vehicle floor.

[0045] It should be noted that after the front pillar outer panel 200 and the vehicle floor are assembled, the front pillar outer panel 200 and the vehicle floor are welded by an external welding robot. The welding robot can be any welding robot available in the prior art.

[0046] Furthermore, the assembly equipment 100 also includes a PLC control system, which serves as a control unit to control the operation of the transport device 1, the assembly robot 21, and the transfer robot 31. It should be noted that the selection of the PLC control system and the control logic of the PLC control system for controlling the assembly robot 21 and the transfer robot 31 can adopt existing technologies.

[0047] Please see Figures 2-5 In one embodiment, the transport device 1 includes a frame 13 and a conveying mechanism 14. The two opposite ends of the frame 13 along its extension direction are a loading end 11 and a unloading end 12, respectively. The conveying mechanism 14 is disposed on the frame 13 and includes a guide rail 141, a drive module, and a hook 142 for mounting the front column outer plate 200. The guide rail 141 extends from the loading end 11 to the unloading end 12. The hook 142 is slidably mounted on the guide rail 141. The drive module is used to drive the hook 142 mounted on the guide rail 141 to slide along the guide rail 141.

[0048] Understandably, the transport device 1 includes a frame 13 and a conveying mechanism 14 mounted on the frame 13. The conveying mechanism 14 includes a guide rail 141, a hook 142, and a drive module. The hook 142 is attached to the guide rail 141. By attaching the front column outer plate 200 to the hook 142 and driving the hook 142 to move along the guide rail 141 through the drive module, the front column outer plate 200 slides along the guide rail 141 between the loading end 11 and the unloading end 12, thereby realizing the automated transport of the front column outer plate 200. Furthermore, the guide rail 141 enables the front column outer plate 200 to remain stable and not easily shake during transport, resulting in better stability.

[0049] It should be noted that multiple hooks 142 can be attached to the guide rail 141 at the same time, and each hook 142 can hold a front column outer panel 200, thereby realizing the simultaneous transportation of multiple front column outer panels 200, which is more efficient.

[0050] In one embodiment, the drive module includes a rotary drive assembly 143 and a transmission assembly 144. The transmission assembly 144 includes a chain 1441, a drive sprocket, and a driven sprocket 1442. The drive sprocket and the driven sprocket 1442 are rotatably disposed at both ends of the guide rail 141. The rotary drive assembly 143 is mounted on the frame 13 and connected to the drive sprocket. The chain 1441 is sleeved on the drive sprocket and the driven sprocket 1442. The top of the hook 142 is slidably supported on the guide rail 141 and the chain 1441. The rotary drive assembly 143 drives the drive sprocket to rotate, so that the hook 142 can slide along the guide rail 141 between the loading end 11 and the unloading end 12 via the chain 1441.

[0051] In this embodiment, a drive sprocket and a driven sprocket 1442 are provided at both ends of the guide rail 141, and a chain 1441 is sleeved on the drive sprocket and the driven sprocket 1442. The drive sprocket is driven to rotate by the rotation drive assembly 143, so that the chain 1441 moves along the extension direction of the guide rail 141. Since the top of the hook 142 is also supported on the chain 1441, the hook 142 slides relative to the guide rail 141 as the chain 1441 moves. The chain 1441 transmission is reliable and can drive the hook 142 to move stably and uniformly, with good reliability.

[0052] Furthermore, the rotary drive assembly 143 includes a rotary drive component and a transmission chain. A drive wheel is mounted on the drive shaft of the rotary drive component. The drive wheel is connected to the drive sprocket via the transmission chain. The rotary drive component drives the drive wheel to rotate, thereby driving the drive sprocket to rotate via the transmission chain.

[0053] It should be noted that the rotary drive component can be a drive motor from the existing technology.

[0054] In one embodiment, the guide rail 141 includes two slide plates 1411, which are spaced apart and form a groove 1412 between them. A transmission component 144 is provided for each slide plate 1411, and two drive sprockets are connected for transmission. A chain 1441 is sleeved on the two sprockets on the same slide plate 1411. A hook 142 passes through the groove 1412, and a support plate 1421 is provided on the top of the hook 142. The support plate 1421 supports the top of the two chains 1441.

[0055] The guide rail 141 includes two sliding plates 1411, with a groove 1412 formed between them. A hook 142 passes through the groove 1412, which provides a limiting and guiding channel for the hook 142, preventing it from shifting or wobbling during sliding, thus improving the stability and reliability of transporting the front column outer panel 200. Furthermore, by providing transmission components 144 on both sliding plates 1411, and a chain 1441 on each sliding plate 1411, and a support plate 1421 on the top of the hook 142, the support plate 1421 supports the two chains 1441, ensuring that the weight of the front column outer panel 200 hanging on the hook 142 is evenly distributed across the two chains 1441, resulting in more stable transport.

[0056] Specifically, each slide plate 1411 forms a guide channel, and the top of the slide plate 1411 is provided with a guide groove communicating with the guide channel. The chain 1441 passes through the guide channel, and the top of the chain 1441 protrudes from the guide groove to support the support plate 1421.

[0057] Furthermore, the hook 142 has two bent hooks 1422 spaced apart vertically, and the front pillar outer plate 200 has two through holes into which the bent hooks 1422 can be inserted. By having the two bent hooks 1422 cooperate with the two through holes, the front pillar outer plate 200 can be prevented from shaking during transportation.

[0058] In one embodiment, the conveying mechanism 14 includes two guide rails 141 and two drive modules. The two guide rails 141 are a first guide rail 141a and a second guide rail 141b, and the two drive modules are a first drive module and a second drive module. The first drive module is used to drive the hook 142 attached to the first guide rail 141a to slide from the loading end 11 to the unloading end 12. The conveying device 1 also includes a transfer mechanism 145, which is disposed on the frame 13 and close to the unloading end 12. The transfer mechanism 145 is used to pick up the hook 142 on the first guide rail 141a that has slid to the unloading end 12 and transfer the hook 142 to the second guide rail 141b. The second drive module is used to drive the hook 142 attached to the second guide rail 141b to slide from the unloading end 12 to the loading end 11.

[0059] Understandably, by setting up two guide rails 141 and two drive modules, and by setting up a transfer mechanism 145, after the transfer robot 31 transfers the front column outer plate 200 on the hook 142, the transfer mechanism 145 can transfer the hook 142 from the first guide rail 141a to the second guide rail 141b, and the second guide rail 141b can transport the hook 142 to the loading end 11. By setting up the transfer mechanism 145 to pick up the hook 142 on the first guide rail 141a, the hook 142 is ensured to be stable, thereby facilitating the transfer robot 31 to transfer the front column outer plate 200 on it.

[0060] Specifically, the transfer mechanism 145 includes a transfer block and a crossbeam, wherein the transfer block is slidably attached to the crossbeam. The transfer block is used to pick up the hook 142 on the first guide rail 141a and slide to the unloading end 12. The transfer block slides along the crossbeam to attach the hook 142 to the second guide rail 141b. Specifically, the transfer block can be driven by a cylinder to slide along the crossbeam.

[0061] In one embodiment, the transport device 1 includes two conveying mechanisms 14 arranged side by side. By providing two conveying mechanisms 14, the transport efficiency is improved for conveying the front pillar outer panels 200 to be installed on different sides of the vehicle body floor.

[0062] More specifically, the two conveying mechanisms 14 described above transport the left front pillar outer panel 200 and the right front pillar outer panel 200, respectively.

[0063] Please see Figure 1 and Figure 6 In one embodiment, both the assembly robot 21 and the transfer robot 31 include a robotic arm 211 and a pick-and-place mechanism 212. The pick-and-place mechanism 212 includes a support column 2121 and at least one pick-and-place component. The support column 2121 is rotatably connected to the robotic arm 211. The pick-and-place component includes two positioning pins 2122 spaced apart on the same side of the support column 2121. The front column outer plate 200 has two positioning holes into which the two positioning pins 2122 extend.

[0064] Understandably, both the transfer robot 31 and the assembly robot 21 include a robotic arm 211 and a pick-and-place mechanism 212. The pick-and-place mechanism 212 includes a support column and at least one pick-and-place component. The pick-and-place component includes two positioning pins 2122. The outer plate 200 of the front column has two positioning holes for the two positioning pins 2122 to extend into. When the transfer robot 31 picks up the outer plate 200 of the front column from the transport mechanism at the unloading end 12, the robotic arm 211 drives the pick-and-place mechanism 212 to move, so that the two positioning pins 2122 extend into the two positioning holes respectively, thereby accurately grasping the outer plate 200 of the front column. The structure is simple and reliable.

[0065] In one specific embodiment, the pick-and-place mechanism 212 includes two pick-and-place components, which are disposed on opposite sides of the support column 2121. The two pick-and-place components enable the transfer robot 31 and the assembly robot 21 to pick up the two front column outer plates 200 at the same time, reducing the number of movements of the robotic arm 211, thereby improving the handling efficiency and assembly efficiency.

[0066] It should be noted that the robotic arm 211 can be a robotic arm 211 in the prior art.

[0067] In one embodiment, the support column 2121 is further provided with a slide rail 213 and a telescopic drive member 214. The slide rail 213 extends from the end of the support column 2121 away from the robotic arm 211 toward the robotic arm 211. One of the positioning pins 2122 is a fixed positioning pin 2122a, which is fixedly installed on the support column 2121 near the robotic arm 211. The other positioning pin 2122 is a movable positioning pin 2122b that is slidably installed on the slide rail 213. The movable positioning pin 2122b is connected to the drive shaft of the telescopic drive member 214. The telescopic drive member 214 is used to drive the movable positioning pin 2122b to slide along the slide rail 213 to move closer to or away from the fixed positioning pin 2122a.
