Description

Technical Field

[0001] This utility model belongs to the field of product testing technology, and in particular relates to an automobile assembly testing line. Background Technology

[0002] As a typical representative of modern manufacturing, the automotive industry is characterized by complex processes, high assembly precision requirements, and tight production cycles. With increasingly fierce market competition and ever-rising consumer demands for product quality, automotive manufacturers face multiple pressures: ensuring consistent product quality, improving production efficiency, and reducing manufacturing costs. As the final stage of vehicle manufacturing, the technical level and reliability of the inspection stations in the final assembly workshop directly determine the final quality of the vehicles leaving the factory.

[0003] In traditional automobile assembly lines, there are several problems that urgently need to be addressed in the quality inspection process.

[0004] First, the testing process is often isolated, with insufficient connection between the testing of each component and the final assembly stage. Information flow may be fragmented, which not only affects production efficiency but also makes quality traceability difficult.

[0005] Secondly, the overall automation rate of the final assembly workshop is still at a low level (about 10%), and labor costs account for as much as 35% of production costs. Improving the level of automation through technological innovation is a key way to reduce costs and increase efficiency.

[0006] Therefore, there is an urgent need to design an automotive final assembly testing line to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this invention is to provide an automobile final assembly testing line that has the advantage of seamless collaboration among various testing stations, and solves the problems mentioned in the background art.

[0008] To achieve the above objectives, the specific technical solution of this utility model for an automobile final assembly and testing line is as follows: An automotive assembly line includes a tire and wheel hub inspection station, a frame inspection station, a side panel inspection station, and a vehicle body inspection station. The tire and wheel hub inspection station inspects tires and wheels. Qualified tires and wheels are assembled with the frame. The assembled frame then enters the frame inspection station, where it inspects the frame interior trim and the distance between wheel arches and wheels. Simultaneously with the frame inspection station, the side panel inspection station inspects the side panels. Qualified frames are assembled with qualified side panels. The assembled vehicle body then enters the vehicle body inspection station, where it inspects the exterior trim of the vehicle body.

[0009] Furthermore, a first assembly station is set up between the tire and wheel hub inspection station and the chassis inspection station, where qualified tires and wheels are assembled with the chassis.

[0010] Furthermore, a second assembly station is set up between the frame inspection station and the side panel inspection station and the body inspection station. The second assembly station assembles the qualified frame and the qualified side panel.

[0011] Furthermore, the tire and wheel hub inspection station includes a roller conveyor, a first inspection component, a stopper, and a first distance measuring switch. The roller conveyor is used to transport tires and wheel hubs. The first inspection component is located directly above the roller conveyor and can capture the tire's OCR characters and the wheel hub's shape. The stopper is located on one side of the roller conveyor and is retractable to block or allow the tire and wheel hub to pass. After the stopper blocks the tire and wheel hub, the first distance measuring switch transmits the tire and wheel hub's arrival signal to the controller. The controller controls the first inspection component to capture the tire's OCR characters and the wheel hub's shape. After the first inspection component completes the capture, the stopper allows the tire and wheel hub to pass.

[0012] Furthermore, the first detection component includes a first industrial camera, which is used to capture tire OCR characters and wheel hub shapes.

[0013] Furthermore, the chassis inspection station includes a first plate chain and two first supports. The first plate chain is used to transport the chassis after the tires and wheels are assembled. The two first supports are located at both ends of the first plate chain. The first supports are equipped with a second distance measuring switch and a second detection component. When the vehicle moves forward, the second distance measuring switch is triggered, and the second distance measuring switch transmits the position signal to the controller. The controller controls the second detection component to take pictures.

[0014] Furthermore, the second detection component includes three second industrial cameras: two second industrial cameras for photographing vehicle nameplates, exterior and interior trim, and the remaining second industrial camera for measuring wheel arches and wheel hub distance.

[0015] Furthermore, each first bracket has three second ranging switches, and each second ranging switch is electrically connected to the corresponding second industrial camera.

[0016] Furthermore, the vehicle body inspection station includes a second plate chain, a third distance measuring switch, and a third inspection component. The second plate chain is used to transport the assembled vehicle body. The third distance measuring switch and the third inspection component are located at opposite ends of the second plate chain. When the vehicle moves forward, the third distance measuring switch is triggered, and the third distance measuring switch transmits the position signal to the controller. The controller then controls the third inspection component to take pictures.

[0017] Furthermore, the third detection component includes three spherical cameras that capture images of the doors, rearview mirrors, and front and rear bumper radars.

[0018] This utility model has the following advantages: This automobile assembly and testing line organically links the testing of key components such as tires, wheels, frames, side panels, and vehicle bodies, fundamentally breaking the "island-like" layout in the background technology. Furthermore, by testing the frame after tire and wheel assembly at the frame testing station, the side panel testing station tests the side panel, thereby significantly shortening the production cycle and effectively reducing the total vehicle testing waiting time.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0022] The following is a reference to the appendix. Figure 1 To be continued Figure 6 This utility model describes an automobile final assembly testing line.

[0023] Currently, in traditional automobile assembly lines, the testing process is often isolated, with insufficient connection between the testing of various components and the final assembly process. Information flow may be disrupted, which not only affects production efficiency but also makes quality traceability difficult. Furthermore, the overall automation rate of the final assembly workshop is still at a low level (about 10%), and labor costs account for as much as 35% of production costs. Improving the level of automation through technological innovation is a key way to reduce costs and increase efficiency.

[0024] Therefore, this automotive assembly and testing line includes a tire and wheel hub testing station 1, a frame testing station 2, a side panel testing station, and a body testing station 3. The tire and wheel hub testing station 1 can test tires and wheels. Qualified tires and wheels are assembled with the frame. The frame after tire and wheel hub assembly enters the frame testing station 2. The frame testing station 2 tests the interior trim of the frame and the distance between the wheel arches and wheels. While the frame testing station 2 tests the frame after tire and wheel hub assembly, the side panel testing station tests the side panels. Qualified frames are assembled with qualified side panels. The assembled body enters the body testing station 3. The body testing station 3 tests the exterior trim of the body.

[0025] This automotive assembly and testing line organically links the testing of key components such as tires, rims, frames, side panels, and bodies, fundamentally breaking the "island-like" layout of the prior art. Furthermore, by testing the frame after tire and rim assembly at frame testing station 2, while the side panel testing station tests the side panels, the production cycle can be significantly shortened, effectively reducing the total vehicle testing waiting time.

[0026] Specifically, a first assembly station is set up between the tire and wheel hub inspection station 1 and the frame inspection station 2, where qualified tires and wheels are assembled with the frame; a second assembly station is set up between the frame inspection station 2 and the side panel inspection station and the vehicle body inspection station 3, where qualified frames are assembled with qualified side panels.

[0027] The tire and rim inspection station 1 includes a roller conveyor 11, a first inspection component 15, a stopper 13, and a first distance measuring switch 14. The roller conveyor 11 is used to transport tires and rims. The first inspection component 15 is located directly above the roller conveyor 11 and can capture the tire's OCR characters and the rim's shape. The stopper 13 is located on one side of the roller conveyor 11 and is retractable to block or allow the tire and rim to pass. Specifically, after the stopper 13 blocks the tire and rim, the first distance measuring switch 14 sends a signal indicating that the tire and rim are in position. The data is transmitted to the controller, which stops the conveyor belt 11 and simultaneously controls the first detection component 15 to capture the tire OCR characters and the wheel hub shape. After the first detection component 15 completes the capture, the stopper 13 releases the tire and wheel hub, and the conveyor belt 11 starts. When the tire and wheel hub leave the position of the stopper 13, the stopper 13 resets to block and limit the next tire and wheel hub. By capturing images of the tire and wheel hub in a stationary state after being blocked, the clarity and accuracy of the image acquisition are ensured, and the detection quality is guaranteed.

[0028] Specifically, the first detection component 15 includes a first industrial camera 151, which is used to capture tire OCR characters and wheel rim shapes. The first industrial camera 151 is responsible for both tire OCR (for identification traceability) and wheel rim shape (quality inspection) tasks. While ensuring functionality, it helps to reduce equipment complexity and cost.

[0029] Preferably, the tire hub inspection station 1 further includes a lift 12, and the first inspection component 15 and the first distance measuring switch 14 are both fixedly connected to the lifting end of the lift 12. The lift 12 controls the height of the first inspection component 15 and the first distance measuring switch 14.

[0030] When inspecting tires and rims, the first distance measuring switch 14 is triggered once. A single trigger indicates that the queue is complete. Qualified tires and rims flow into the next station, while unqualified tires and rims trigger an audio prompt to remind manual re-inspection.

[0031] Furthermore, the chassis inspection station 2 includes a first plate chain 21 and two first supports. The first plate chain 21 is used to transport the chassis after the tires and wheels are assembled. The two first supports are located at both ends of the first plate chain 21. The first supports are equipped with a second distance measuring switch 22 and a second detection component 23 to take pictures of both sides of the chassis. When the vehicle moves forward, the second distance measuring switch 22 is triggered. The second distance measuring switch 22 transmits the position signal to the controller. The controller controls the second detection component 23 to take pictures. Specifically, the second detection component 23 includes three second industrial cameras 231. Two second industrial cameras 231 take pictures of the vehicle body nameplate, exterior body decoration and interior, and the remaining second industrial camera 231 takes pictures of the wheel arch and wheel hub distance.

[0032] There are three second ranging switches 22 on each first bracket. Each second ranging switch 22 is electrically connected to the corresponding second industrial camera 231, so that the triggering of each second industrial camera 231 is independent. It can take pictures according to the different positions of the vehicle frame, avoiding the problem of inaccurate shooting timing caused by a single trigger, and greatly improving the accuracy and reliability of detection.

[0033] When inspecting the chassis after the tires and rims are assembled, the second distance measuring switch 22 is triggered twice. The completion of the two triggers indicates that the queue is complete. Qualified chassis flow into the next station, while unqualified chassis trigger an audio prompt to remind manual re-inspection.

[0034] The side panel inspection station includes a lifting device, a fourth distance measuring switch, and a fourth inspection component. The lifting device is used to suspend the side panel and move it. The fourth distance measuring switch and the fourth inspection component are located on both sides of the lifting device. When the side panel moves forward, it triggers the fourth distance measuring switch, which transmits the positioning signal to the controller. The controller then controls the fourth inspection component to take pictures. Specifically, the fourth inspection component includes two fourth industrial cameras, which take pictures of the side panel appearance and components.

[0035] During the inspection of the side panels, the fourth distance measuring switch is triggered once. A single trigger indicates that the queue is complete. Qualified side panels flow into the next workstation, while unqualified side panels trigger an audio prompt to remind manual re-inspection.

[0036] The vehicle body inspection station 3 includes a second plate chain 31, a third distance measuring switch 32, and a third detection component 33. The second plate chain 31 is used to transport the assembled vehicle body. The third distance measuring switch 32 and the third detection component 33 are located at the two ends of the second plate chain 31, respectively. When the vehicle moves forward, the third distance measuring switch 32 is triggered, and the third distance measuring switch 32 transmits the position signal to the controller. The controller controls the third detection component 33 to take pictures. Specifically, the third detection component 33 includes three spherical cameras 331, which take pictures of the doors, rearview mirrors, and front and rear bumper radars.

[0037] During vehicle inspection, the third distance measuring switch 32 is triggered twice. The completion of the two triggers indicates that the queue is complete. Qualified vehicles flow into the next workstation, while unqualified vehicles trigger an audio prompt to remind manual re-inspection.

[0038] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
