Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile production, and in particular to a vehicle off-line auxiliary device. Background Technology
[0002] The final step in the automobile production line is the vehicle conveying process. After passing through various processes, vehicles are transported one after another off the conveyor belt, becoming finished cars. During this process, when a vehicle reaches the end of the conveyor belt, it is usually manually driven to the next workstation. However, the wheel pressure of existing AGVs (Automated Guided Vehicles, or mobile robots) is much greater than that of automobile tires, which can damage the plastic conveyor belt used to transport the vehicles. Furthermore, the height difference and large gaps between the end of the conveyor belt and the ground prevent AGVs from climbing onto it to move vehicles. Vibrations or positional shifts generated during conveyor belt operation can also affect the smoothness of AGV vehicle reception. Utility Model Content

Detailed Implementation
[0021] To more clearly illustrate the purpose, technical solution, and advantages of the embodiments of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. A clear and complete description will be provided. Obviously, the described embodiments are some, but not all, embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.
[0022] Examples of embodiments of this utility model Figures 1 to 5 As shown, a vehicle off-line auxiliary device includes a front transition plate 1, a middle plate 2 at the rear end of the front transition plate 1, and a tail plate 3 with an inclined top surface connected to the end of the middle plate 2 away from the front transition plate 1. First conveyor belts 4, made of multiple bearings arranged in a matrix, are arranged on both the left and right sides of the front transition plate 1 and extend to the front end of the tail plate 3. In other words, in the middle position, from front to back, there is a middle support plate consisting of the front transition plate 1, the middle plate 2, and the tail plate 3, all with equal width in the left and right directions. This disperses the forces experienced during vehicle transport and improves structural strength. A first conveyor belt 4 is arranged on the left and right sides of the middle support plate, forming a transition device for vehicles from the second conveyor belt 62 to the AGV, constituting an auxiliary device for vehicles off the second conveyor belt 62. The inclined surface of the tail plate 3 slopes downwards from front to back. The first conveyor belt 4 is composed of multiple bearings 41 and multiple shafts... The bearings 41 are arranged in a matrix. When a vehicle is transported from the second conveyor belt 62 to the first conveyor belt 4, the low-friction rolling of the bearings 41 replaces the traditional power conveyor belt for transporting the vehicle. It can roll using only the residual power of the conveyor belt, assisting the vehicle to move smoothly without additional drive. At the same time, the bearings 41 also provide lateral restraint to prevent the vehicle from deviating. Deep groove ball bearings are selected for bearings 41. Deep groove ball bearings can withstand large radial loads and can also operate well under combined radial and axial loads. At this time, the tail end of the left first conveyor belt 4 extends to the front left side of the tail plate 3, and the tail end of the right first conveyor belt 4 extends to the front right side of the tail plate 3. This allows the AGV to be located in the area formed by the two sides of the tail plate 3 and the tail end of the first conveyor belt 4. The AGV can stably dock with the vehicle tires to move the vehicle. The first conveyor belt 4 also reduces the inertia of the vehicle, thus avoiding potential damage when it slips onto the AGV.
[0023] Further improvements, such as Figure 1 Place Figure 5 As shown, for each of the first conveyor belts 4, each first conveyor belt 4 includes multiple bearing conveying assemblies connected sequentially from front to back. Each bearing conveying assembly includes a bearing housing, multiple rotating shafts 40 arranged parallel to each other on the bearing housing from front to back, and multiple bearings 41 sleeved on the rotating shafts 40 and partially protruding from the top surface of the bearing housing. For example, four rotating shafts 40 are arranged at intervals from front to back on the bearing housing. The rotating shafts are screws with external threads at both ends. Multiple bearings 41 are provided on each rotating shaft 40 to form a bearing conveying assembly. Both ends of the rotating shaft 40 are connected to the bearing housing from both ends. The shaft 40 is installed on the bearing housing by threading nuts onto both ends of the shaft through the side. The connection between adjacent bearing transmission assemblies involves connecting the two ends of the rearmost shaft 40 on the bearing housing of the front bearing transmission assembly and the two ends of the foremost shaft 40 on the bearing housing of the rear bearing transmission assembly via a first connecting plate 44. The front and rear sides of the first connecting plate 44 have corresponding through holes fitted onto the shaft 40. Nuts are then installed onto the corresponding shaft 40. This connection of multiple bearing transmission assemblies forms the first conveyor belt 4, ensuring structural stability during the rolling transport of vehicles. For the bearing housing, as... Figure 4 As shown, the bearing housing includes multiple strip plates 42 arranged parallel to each other from left to right. Each strip plate 42 has multiple first through holes for the shaft 40 to pass through, spaced apart along the front-rear direction. This simplifies the structure of the bearing housing and divides the multiple bearings 41 on the bearing housing into multiple regions. Each region is formed between two adjacent strip plates 42, which further improves the stability of the bearing transmission assembly, prevents vehicle deviation, and achieves smooth vehicle transfer. At the same time, a washer 43 is provided between two adjacent bearings 41 on the same shaft 40 to prevent frictional damage between the two bearings 41. A washer 43 is also provided between the bearing 41 at the end of the shaft 40 and the strip plate 42 to prevent frictional damage to the bearing.
[0024] Further improvements, such as Figure 3 As shown, each first conveyor belt 4 has a side transition plate 5 at the front end on the side opposite to the front transition plate 1. That is, a side transition plate 5 is set on the left side of the front end of the left first conveyor belt 4, and a side transition plate 5 is also set on the right side of the front end of the right first conveyor belt 4. The side transition plates 5 are used to improve the support strength of the vehicle when it transitions from the second conveyor belt 62 to the first conveyor belt 4.
[0025] Further improvements, such as Figure 3 and Figure 5As shown, the intermediate plate 2 includes a plurality of second connecting plates 20 connected sequentially from front to back. The bottom surface of the second connecting plate 20 is provided with reinforcing rods 21. The plurality of second connecting plates 20 further disperse the forces exerted on the vehicle during the transmission process and improve the structural strength. The tail plate 3 is connected to the second connecting plate 20 at the very end. The bottom surface of each second connecting plate 20 is provided with a plurality of reinforcing rods 21, and the plurality of reinforcing rods 21 are spaced apart along the conveying direction of the first conveyor belt 4.
[0026] Further improvements, such as Figure 1 and Figure 2 The diagram also includes a foundation 6, on which a first groove 60 is provided and a second groove 61 connected to and perpendicular to the first groove 60 is provided. The first groove 60 is arranged in a left-right direction, and the second groove 61 is arranged in a front-back direction. A second conveyor belt 62 of a transport vehicle is installed in the second groove 61. The second conveyor belt 62 can be any existing conveyor belt of a transport vehicle. The tail end of the second conveyor belt 62 extends into the first groove 60 and is located at the front end of the front transition plate 1. The power unit that drives the second conveyor belt 62 can be installed in the first groove 60. A mounting frame 63 is provided, which serves as a bracket for mounting the power unit that drives the second conveyor belt 62. The front transition plate 1, the front part of the middle plate 2, and the front part of the first conveyor belt 4 are all mounted on the top of the mounting frame 63. The tail plate 3, the tail of the middle plate 2, and the tail of the first conveyor belt 4 are all set on the foundation 6 and located at the end of the first groove 60 opposite to the second conveyor belt 62. That is, the second conveyor belt 62 is located on the foundation 6 in front of the first groove 60, and the tail plate 3, the tail of the middle plate 2, and the tail of the first conveyor belt 4 are all located on the foundation 6 behind the first groove 60, facilitating vehicle transfer after decommissioning. To facilitate the installation of the first conveyor belt 4 on the mounting frame 63, the first conveyor belt 4 is mounted on the mounting frame 63 via a base plate 7 located at the bottom of the first conveyor belt 4. Figure 5As shown, four longitudinal strip base plates extending along the conveying direction of the first conveyor belt 4 are arranged sequentially from left to right. At the front end of these four longitudinal strip base plates, three transverse strip base plates extending perpendicular to the conveying direction of the first conveyor belt 4 are arranged sequentially from left to right. The three transverse strip base plates connect to the front end of the four longitudinal strip base plates to form a T-shaped structure. The left end of the leftmost longitudinal strip base plate extends out to the left end of the left side of the first conveyor belt 4, and similarly, the right end of the rightmost longitudinal strip base plate extends out to the right end of the right side of the first conveyor belt 4. The two middle longitudinal strip base plates are located at the bottom of the middle plate 2. Meanwhile, the connection positions of the two longitudinal strip base plates on the left correspond to the bottom of the first conveyor belt 4 on the left, and the connection positions of the two longitudinal strip base plates on the right correspond to the bottom of the first conveyor belt 4 on the right. This facilitates the installation of the first conveyor belt 4 on the mounting frame 63 and also improves the structural strength of the offline auxiliary device. Correspondingly, a top through hole is provided in the middle of the top of the strip plate 42, and then the strip plate 42 is connected to the mounting frame 63 using screws passing through the top through hole. When a base plate 7 is provided, the strip plate 42 is connected to the base plate 7 using screws passing through the top through hole, and the base plate 7 is then connected to the mounting frame 63 using screws. A further improvement is that the front transition plate 1, the bearing seat of the bearing conveyor assembly at the foremost end, and the side transition plate 5 can all be installed on the mounting frame 63 by hinges for convenient use. At this time, a support frame for supporting the front transition plate 1 and the bearing housing can be detachably installed on the mounting bracket 63. The support frame is provided with through holes, and the mounting bracket 63 is provided with multiple threaded holes at intervals in the vertical direction. Then, according to the requirements, the support frame is installed at the corresponding height by the cooperation of screws and threaded holes. The bottom surfaces of the front transition plate 1 and the bearing housing press against the top of the support frame. Preferably, a support frame is provided for the front transition plate 1 and the bearing housing respectively.
[0027] Further improvements include a monitoring device (not shown in the figure) for monitoring vehicle position. This device monitors the position of the transported vehicles to prevent damage caused by a collision between the following vehicles and the preceding vehicles if the preceding vehicles are not removed from the line in time. The monitoring device can be a lidar or ultrasonic sensor suspended in the workshop or mounted on the foundation 6 and facing the second conveyor belt 62. When a failure to remove the vehicle from the line is detected, the device transmits information to the vehicle removal system and stops the transport of the vehicles.
[0028] Although the present invention has been described in detail above with general description and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
