Description

Technical Field

[0001] This invention relates to the field of automotive assembly technology, and in particular to a complete vehicle body assembly. Background Technology

[0002] Automotive assembly refers to the process of welding together the chassis, side panels, roof beams, roof, and other components to form the body-in-white (the car body before painting). Automotive assembly plays a crucial role in automobile manufacturing. It involves the assembly and welding of the body-in-white, ensuring the correct connection of all components to form a complete body structure. This process requires precise positioning and high-quality welding to ensure the strength and safety of the car body.

[0003] Existing assembly methods include flexible assembly, open assembly, and assembly using two independent body-in-white assemblies. However, flexible assembly has drawbacks: single-row, extended-cab, and double-row models are designed and manufactured with their own independent grippers, sharing only a fixed frame, or there is no fixed frame; the robot simply grasps each dedicated gripper and assembles them together via a fixed frame, or they are assembled by interconnecting the grippers without a frame, in order to solve problems related to robot load and welding accessibility. This tooling method, which uses a dedicated gripper for each model, has a large footprint, high investment, poor gripper rigidity, and poor dimensional stability. The disadvantages of using open assembly: Designing and manufacturing separate assembly fixtures for single-row, extended-cab, and double-row trucks, storing them in dedicated areas, and moving the fixtures in and out sequentially via fixture slides to the assembly station for vehicle model switching requires a huge fixture storage area as a fixture library, as well as a huge fixture switching area to move and combine single-row, extended-cab, and double-row fixtures. This presents significant space and investment challenges, and is rarely used in the light truck industry. The disadvantages of using two separate body-in-white assembly fixtures: Designing and manufacturing separate body-in-white assembly fixtures for single-row / extended-cab and double-row trucks, each with its own dedicated space and welding equipment, essentially creates two separate assembly fixtures. When producing one vehicle model, the fixtures and equipment for the other model are idle, requiring double the space and investment.

[0004] Therefore, there is an urgent need for a vehicle assembly system that can meet the functions of single-row / cab-and-half-row and double-row vehicle assembly, while also having high equipment and site utilization. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a vehicle assembly system that solves the problem in the prior art of lacking a vehicle assembly system that satisfies both single-row / cab-and-half-row and double-row vehicle assembly functions while also achieving high equipment and site utilization.

[0006] The vehicle body assembly proposed in this invention includes a first positioning component, a second positioning component, a split-joining positioning component for connecting the first positioning component and the second positioning component, and a drive device for driving the second positioning component. The first positioning component is used for single-row / half-row vehicle assembly, and the first positioning component and the second positioning component cooperate for double-row vehicle assembly. The split-joining positioning component controls the connection or separation of the first positioning component and the second positioning component to meet the production requirements of single-row, half-row, or double-row vehicle bodies.

[0007] The aforementioned vehicle assembly, by setting up a first positioning component and a second positioning component, where the first positioning component is a single-row / half-row positioning component and the second positioning component is a double-row positioning component, enables the vehicle assembly to realize the assembly functions of single-row, half-row, and double-row vehicles respectively. Furthermore, by setting up a split-joint positioning component and a drive device, the second positioning component and the first positioning component can be connected or separated. When assembling a single-row or half-row vehicle, the second positioning component is driven to move away from the first positioning component; when assembling a double-row vehicle, the second positioning component is driven to move closer to and connect with the first positioning component, cooperating with it to achieve the assembly of the double-row vehicle. Thus, through this setup, a single fixture is used efficiently for assembling different types of vehicles, eliminating the need for multiple sets of fixtures and reducing costs. During mode switching, there is no need to repeatedly put the fixtures back into storage or switch modes; only the position of the second positioning component needs to be moved, greatly reducing the space occupied by the equipment and improving space utilization. Therefore, this invention solves the problem in the prior art of lacking a vehicle assembly that satisfies both single-row / half-row and double-row vehicle assembly functions while achieving high equipment and space utilization.

[0031] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0032] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] Please see Figures 1 to 10 The image shows a vehicle body assembly according to an embodiment of the present invention, including a first positioning component 10, a second positioning component 20, a split-and-join positioning component 30 for connecting the first positioning component 10 and the second positioning component 20, and a drive device 40 for driving the second positioning component 20. The first positioning component 10 is used for single-row / half-row vehicle assembly, and the first positioning component 10 and the second positioning component 20 cooperate for double-row vehicle assembly. The split-and-join positioning component 30 controls the connection or separation of the first positioning component 10 and the second positioning component 20 to meet the production requirements of single-row, half-row, or double-row vehicle bodies.

[0035] Understandably, by setting up a first positioning component 10 and a second positioning component 20, where the first positioning component 10 is a single-row / half-row positioning component and the second positioning component 20 is a double-row positioning component, the vehicle assembly can achieve assembly functions for single-row, half-row, and double-row vehicles respectively. Furthermore, by setting up a split-joining positioning component 30 and a drive device 40, the second positioning component 20 and the first positioning component 10 can be connected or separated. When assembling a single-row or half-row vehicle, the second positioning component 20 is driven to move away from the first positioning component 10. When assembling a double-row vehicle, the second positioning component 20 is driven to move closer to and connect with the first positioning component 10, cooperating with the first positioning component 10 to achieve the assembly of the double-row vehicle. Thus, through this setup, a single set of fixtures is rationally used for assembling different types of vehicles, eliminating the need for multiple sets of fixtures and reducing costs. During mode switching, there is no need to repeatedly put the fixtures back into storage or switch them; only the position of the second positioning component 20 needs to be moved, greatly reducing the space occupied by the equipment and improving space utilization. Therefore, the present invention solves the problem in the prior art of lacking a vehicle assembly method that satisfies both single-row / cab-and-half-row and double-row vehicle assembly functions, and also has high equipment and site utilization.

[0036] Specifically, the split-and-join positioning assembly 30 includes a guide component 31 respectively disposed on the first positioning assembly 10 and the second positioning assembly 20, a drive component 32 disposed on the first positioning assembly 10, a positioning rod 33 connected to the drive component 32, and a limiting shell 34 disposed on the second positioning assembly 20. The positioning rod 33 is adapted to the guide component 31. The guide component 31 of the second positioning assembly 20 is disposed inside the limiting shell 34 and partially protrudes from the limiting shell 34. The drive component 32 is used to drive the positioning rod 33 to move closer to or away from the limiting shell 34. By setting the positioning rod 33 and the guide component, when it is necessary to assemble a double-row vehicle body, the positioning rod 33 cooperates with the limiting shell 34 to lock and position the second positioning assembly 20 in a predetermined position to cooperate with the first positioning assembly 10 for double-row vehicle assembly. When it is necessary to assemble a single-row or half-row vehicle body, the positioning rod 33 resets, allowing the second positioning assembly 20 to move, freeing up space for single-row or half-row vehicles to be assembled through the first positioning assembly 10.

[0037] Additionally, the guiding components include a concave fixing seat 311 and guide wheels 312 disposed on both sides of the top of the concave fixing seat 311. The positioning rod 33 is placed inside the concave fixing seat 311 and guided by the two guide wheels 312. In specific implementation, the guide wheels 312 disposed on both sides of the concave fixing seat limit and guide the positioning rod 33, allowing the positioning rod 33 to move along a preset direction. Furthermore, the guide wheels 312 and the positioning rod 33 slide against each other, reducing wear and tear and improving service life.

[0038] Specifically, the vehicle assembly also includes an assembly platform 50. The first positioning component 10 and the second positioning component 20 both include a bracket 11 and a clamping component 12 located on one side of the bracket 11. The bracket 11 is mounted on the assembly platform 50.

[0039] Additionally, the first positioning component 10 and the second positioning component 20 are respectively provided with a positioning pin component 13 and a positioning block component 212 on opposite sides. The positioning pin component 13 and the positioning block component 212 are adapted to connect or separate the first positioning component 10 and the second positioning component 20. The bracket 11 of the second positioning component 20 is connected to the assembly platform 50 through the track assembly 60. A drive device 40 is provided on one side of the bracket 11 of the first positioning component 10. The drive device 40 is used to drive the track assembly 60 to move the second positioning component 20 closer to or further away from the first positioning component 10. By setting up the assembly platform 50 and the track assembly 60, when the separation positioning component 30 between the first positioning component 10 and the second positioning component 20 is separated, the drive device 40 causes the second positioning component 20 to move back and forth under the left and right sides of the track assembly 60, thereby separating the second positioning component 20 from the first positioning component 10 and providing space for single-row or half-row vehicle assembly.

[0040] Specifically, the positioning block 212 component 21 includes a connecting plate 211 connected to the bracket 11, a positioning block 212 disposed on the connecting plate 211, and a positioning hole 213 formed on the positioning block 212. The positioning pin component 13 includes an output rod 132 connected to a cylinder 131 and a protective shell 133 sleeved on the outside of the output rod 132. The output rod 132 is adapted to the positioning hole 213. The cylinder 131 drives the output rod 132 to cooperate with the positioning hole 213, so that the first positioning components 10 are connected and fixed or separated.

[0041] In addition, multiple positioning pin components 13 and positioning block components 212 are all located on the side of the bracket 11. Furthermore, by adding multiple positioning pin components 13 and positioning block components 212 to cooperate with each other, the positioning effect between the first positioning component 10 and the second positioning component 20 is further improved through multi-point positioning, ensuring proper assembly and thus ensuring the assembly effect of different assembly modes of the overall vehicle body assembly.

[0042] Specifically, the bracket 11 of the first positioning component 10 is provided with a single-row clamp component 14 on the side near the second positioning component 20. The single-row clamp component 14 is connected to the bracket 11 through a sliding connection component 15, which is used to drive the single-row clamp component 14 to move closer to or away from the second positioning component 20. In addition, the first positioning component 10 is also provided with a single-row clamp. When half-row assembly is required, the single-row clamp is driven to move through the sliding connection component 15 to make room for half-row vehicle assembly. When single-row assembly is required, the single-row clamp is reset through the sliding connection component 15, so that the single-row clamp and the clamp component 12 fixed in position on the bracket 11 of the first positioning component 10 cooperate with each other to assemble the single-row vehicle.

[0043] Furthermore, the sliding connection assembly 15 includes a slide rail frame 151 and a drive device 152 mounted on the bracket 11. The single-row clamp component 14 is provided with a slider adapted to the slide rail frame 151. The drive device 152 is used to drive the single-row clamp component 14 to move closer to or further away from the second positioning assembly 20. Specifically, by setting the slide rail frame 151 and the slider to cooperate, the single-row clamp can slide left and right on the bracket 11 of the first positioning assembly 10 with the action of the drive device 152, realizing the switching of different assembly modes of the vehicle body assembly.

[0044] In summary, the vehicle assembly in the above embodiments of the present invention, by setting a first positioning component 10 and a second positioning component 20, wherein the first positioning component 10 is a single-row / half-row positioning component and the second positioning component 20 is a double-row positioning component, enables the vehicle assembly to realize the assembly functions of single-row, half-row, and double-row vehicles respectively. Furthermore, by setting a split-joining positioning component 30 and a driving device 40, the second positioning component 20 and the first positioning component 10 can be connected or separated. When single-row or half-row vehicles need to be assembled, the second positioning component 20 is driven to move away from the first positioning component 10; when double-row vehicles need to be assembled, the second positioning component 20 is driven to move closer to and connect with the first positioning component 10, cooperating with the first positioning component 10 to achieve the assembly of double-row vehicles. Thus, through this setup, a single set of fixtures is rationally used for assembling different types of vehicles, eliminating the need for multiple sets of fixtures and reducing costs. During mode switching, there is no need to repeatedly put the fixtures into storage or switch modes; only the position of the second positioning component 20 needs to be moved, greatly reducing the space occupied by the equipment and improving space utilization. Therefore, the present invention solves the problem in the prior art of lacking a vehicle assembly method that satisfies both single-row / cab-and-half-row and double-row vehicle assembly functions, and also has high equipment and site utilization.
