[0002] In recent years, with the rapid development of the manufacturing industry, various types of automobiles have emerged, and automated assembly lines have also been developed to meet the assembly needs of automobiles.

Therefore, the embodiments of this application are not limited to the specific implementations disclosed below.

[0040] This application provides an automatic tire assembly system.

Figure 5 This is a schematic diagram of the structure provided in the embodiments of this application, showing a tire being transported to a designated location.

[0041] like Figures 1 to 5As shown, this application embodiment provides an automatic tire assembly system 100, assembled on a synchronous conveyor line 20 opposite to the vehicle assembly conveyor 10. The system includes: a pickup device 1, a synchronization device 2, an adjustment bearing device 4, a lifting device 5, and a fine-tuning device 6. The pickup device 1 is located at the end of the tire 8 conveyor line and is used to pick up tires 8 from the conveyor line and transfer them to the adjustment bearing device 4. The synchronization device 2 moves along the synchronous conveyor line 20 and can be synchronized with the vehicle body transport 9 on the vehicle assembly conveyor 10. The lifting device 5 is located on the synchronization device 2, and the adjustment bearing device 4 is connected to the lifting device 5. After the adjustment bearing device 4 carries the tire 8, it adjusts the tire 8 to a first position along a first direction, and then adjusts the tire 8 to a second position along a second direction via the lifting device 5. The fine-tuning device 6 is located on the adjustment bearing device 4. When the tire 8 reaches the second position, the fine-tuning device 6 installs the tire 8 in a designated position on the vehicle 7. The specific structure of each device and the connection relationship between each device will be described in detail below.

[0042] Specifically, in this embodiment, the picking device 1 is located at the end of the tire 8 conveyor line. The tire 8 conveyor line includes a movable support, transmission rollers, a transmission motor, and a transmission chain. The movable support is arranged between the tire 8 production area and the tire 8 assembly area, and its position can be adjusted by wheels on the movable support. The transmission rollers are sequentially distributed on the movable support and are used to transport the tires 8. The transmission motor is fixedly installed at the bottom of the movable support, and the output end of the transmission motor is connected to the transmission chain. The transmission chain is interconnected with each transmission roller so that the output end of the transmission motor drives the transmission chain, causing the transmission rollers to rotate, thereby realizing the transportation of the tires 8. Of course, in this embodiment, the transmission rollers can be set as unpowered rollers.

[0043] Tire 8 is conveyed to a position near the picking device 1 via a tire 8 conveyor line, and the picking device 1 picks up the tire 8 from the tire 8 conveyor line and places it onto the positioning carrier device 4. In this embodiment, the picking device 1 includes a first support 11, a first cylinder (not shown), and a first push rod 12. The first support 11 is located at the end of the tire 8 conveyor line, the first cylinder is located on the first support 11, and the first push rod 12 is connected to the first cylinder along a first horizontal direction toward the positioning carrier device 4. The first cylinder drives the first push rod 12 to extend or retract along the first horizontal direction. In this embodiment, the first horizontal direction is the direction along the horizontal end face of the tire 8 conveyor line toward the positioning carrier device 4. The push head of the first push rod 12 has a structure that matches the tire 8. When the first cylinder drives the first push rod 12 to extend along the first horizontal direction, the push head can make stable contact with the tire 8, thereby picking up the tire 8 onto the positioning carrier device 4.

[0044] Furthermore, in this embodiment, since the tires 8 transported on the tire conveyor line are generally in a horizontal position, while the tires 8 are assembled in a vertical position, it is necessary to stand the tires 8 upright so that they are closer to the assembly position during assembly. Correspondingly, the picking device 1 also includes a flipping bracket 13, a second cylinder 14, and a second push rod (not shown). The second cylinder 14 is disposed on the first support 11, and the second push rod is connected to the second cylinder 14 in a vertical direction. The flipping bracket 13 is connected to the second push rod, and the second cylinder 14 drives the second push rod to extend and retract in a vertical direction, thereby driving the flipping bracket 13 to perform a flipping action. Specifically, in this embodiment, the flipping bracket 13 is provided with multiple rods, and the flipping bracket 13 is connected to a movable bracket. The tires 8 are transferred to the flipping bracket 13 through the rods of the movable bracket. Then, the second cylinder 14 drives the second push rod to extend in a vertical direction, so that the flipping bracket 13 is gradually lifted, thereby flipping the originally horizontal tires 8 90 degrees to an upright position. Finally, the first cylinder drives the first push rod 12 to extend along the first horizontal direction so that the push head of the first push rod 12 can contact the tire 8, thereby picking up the upright tire 8 to the positioning bearing device 4.

[0045] In this embodiment, to promptly install the tire 8 carried by the positioning carrier 4 onto the corresponding vehicle 7, a synchronization device 2 can be used. Specifically, the synchronization device 2 moves along the synchronization conveyor line 20 and can be synchronized with the vehicle body transport 9 on the vehicle assembly conveyor 10. The synchronization conveyor line 20 includes a synchronization chain or a synchronization track. The synchronization device 2 includes a moving device and a synchronization positioning device. The moving device moves along the synchronization conveyor line 20, and the synchronization positioning device is positioned relative to the moving device and the vehicle body transport 9 on the vehicle assembly conveyor 10. Through the synchronization positioning device, the moving device is synchronized with the vehicle body transport 9 on the vehicle assembly conveyor 10.

[0046] Furthermore, in this embodiment, the transfer device includes a transfer trolley 3 and a drive motor 31. The transfer trolley 3 moves along the synchronous conveyor line 20. The transfer trolley 3 is generally cuboid in shape, and transfer wheels 32 are respectively provided at its four corners. The two transfer wheels 32 on the front side are connected by a first connecting shaft, and these two transfer wheels 32 are called active transfer wheels. The two transfer wheels 32 on the rear side are connected by a second connecting shaft, and these two transfer wheels 32 are called driven transfer wheels. The transfer wheels 32 enable the transfer trolley 3 to move. The drive motor 31 is mounted on the transfer trolley 3, and the output end of the drive motor 31 is connected to the transfer wheels 32 of the transfer trolley 3. Specifically, the output end of the drive motor 31 is connected to the first connecting shaft to drive the transfer wheels 32 to move along the synchronous conveyor line 20.

[0047] To achieve precise movement of the transfer device, i.e., to synchronize the transfer device with the vehicle body transport 9 on the vehicle assembly conveyor 10, a synchronization positioning device includes a reflector 33 and a laser detection sensor 34. The reflector 33 is mounted on the chassis of the vehicle body transport 9 on the vehicle assembly conveyor 10, and each chassis of the vehicle body transport 9 is equipped with a reflector 33. The laser detection sensor 34 is positioned at a designated location on the transfer trolley 3. The laser detection sensor 34 acquires the light spot information reflected by the reflector 33 and converts this light spot information into speed information, which is then transmitted to the drive motor 31. Specifically, the laser detection sensor 34 determines the synchronization relationship between the transfer device and the vehicle 7 on the vehicle body transport 9 by the position of the reflected light spot. The speed information of the transfer device is obtained by the difference between the reflected light spot and the origin of the coordinate system. The drive motor 31 controls its own rotation speed based on the speed information to control the running speed of the transfer wheels 32, thereby achieving synchronization with the vehicle 7.

[0048] After the transfer device synchronizes with the vehicle 7, the tire 8 can be transported to the drive axle of the vehicle 7 via the adjusting bearing device 4 and the lifting device 5. The lifting device 5 includes a support base 51, a vertical guide rod 52, a lifting support 53, and a lifting cylinder 54. Specifically, the support base 51 is mounted on the transfer trolley 3, and the vertical guide rod 52 is mounted on the support base 51 along a second direction, which is vertical. Figure 3 (Direction indicated by the longitudinal arrow). The fixed end of the lifting cylinder 54 is fixedly connected to the support base 51, and the driving end of the lifting cylinder 54 is connected to the lifting support 53. The lifting support 53 is fitted onto the vertical guide rod 52, and the driving end of the lifting cylinder 54 drives the lifting support 53 to reciprocate along the vertical guide rod 52. The adjusting bearing device 4 includes a horizontal guide rod 42, a guide rod support 41, an adjusting support 43, and an adjusting cylinder 44. Specifically, the fixed end of the adjusting cylinder 44 is connected to the lifting support 53, and the driving end of the adjusting cylinder 44 is connected to the guide rod support 41. A horizontal guide rod 42 is connected to a lifting support 53 along a first direction. A guide rod support 41 is fitted onto the horizontal guide rod 42 and connected to the adjusting support 43. The driving end of the adjusting cylinder 44 drives the guide rod support 41 to reciprocate along the horizontal guide rod 42, thereby causing the adjusting support 43 to move synchronously with the guide rod support 41. In this embodiment, the adjusting support 43 is used to support the tire 8, and the first direction is the horizontal direction. Figure 3 (The direction indicated by the horizontal arrow in the middle). In addition, this embodiment of the application also includes a shock-absorbing bracket 45, which is disposed relative to the adjusting support 43. When the tire 8 is pushed onto the adjusting support 43, the inertial force of the tire 8 will cause the adjusting support 43 to move downward. In order to prevent the adjusting support 43 from moving downward, the buffer part 46 of the shock-absorbing bracket 45 can abut against the adjusting support 43, so as to keep the adjusting support 43 stable when the tire 8 is pushed onto the adjusting support 43.

[0049] In this embodiment, after the adjusting support 43 acquires the tire 8, the adjusting cylinder 44 drives the adjusting support 43 to move along the horizontal guide rod 42 toward the lifting support 53 in a first direction, thereby achieving a first position adjustment of the tire 8. Then, the lifting cylinder 54 drives the lifting support 53 to move upward along the vertical guide rod 52 in a second direction, thereby achieving a second position adjustment of the tire 8. If the second position adjustment of the tire 8 allows the tire 8 to be mounted on the drive wheel axle of the vehicle 7, then no further position adjustment of the tire 8 is required. At this time, the lifting cylinder 54 drives the lifting support 53 to move downward along the vertical guide rod 52 in the second direction. Then, the adjusting cylinder 44 drives the adjusting support 43 to move away from the lifting support 53 along the horizontal guide rod 42 in the first direction, so that the adjusting support 43 moves to the initial position, where it continues to receive the next tire 8.

[0050] In this embodiment, considering that the tire 8 cannot be directly installed on the drive axle of the vehicle 7 via the adjusting support device 4 and the lifting device 5, it is necessary to fine-tune the tire 8 located in the second position. To address this, the automatic tire assembly system 100 further includes a fine-tuning device 6, which is mounted on the adjusting support device 4. When the tire 8 reaches the second position, the fine-tuning device 6 installs the tire 8 at the designated position (drive axle of the vehicle 7) on the vehicle 7. Specifically, the fine-tuning device 6 includes a first control button (not shown) and a second control button (not shown) respectively located outside the adjusting support 43. The first control button is connected to the lifting cylinder 54 and is used to control the lifting cylinder 54 to move along the second direction (…). Figure 3 The lifting support 53 is driven to reciprocate along the vertical guide rod 52 in the direction indicated by the longitudinal arrow. The second control button is connected to the adjusting cylinder 44 and is used to control the adjusting cylinder 44 to move along the first direction (…). Figure 3 The horizontal arrow in the middle indicates the direction in which the drive adjustment support 43 reciprocates along the horizontal guide rod 42. When the tire 8 reaches the second position, the operator operates the first control button and the second control button respectively to assemble the tire 8 with the drive wheel axle.

[0051] Furthermore, in order to achieve left and right direction of tire 8 in the second position ( Figure 2 The fine-tuning device 6, which is used for fine-tuning in the direction indicated by the horizontal arrow, also includes a third control button (not shown), a guide rod support 41, a third cylinder (not shown), and a third push rod 61. The guide rod support 41 is positioned between the horizontal guide rod 42 and the adjustment support 43. The fixed end of the third cylinder is mounted on the guide rod support 41. The third push rod 61 moves along the second horizontal direction (…). Figure 2As indicated by the longitudinal arrow, the third push rod 61 is connected at one end to the drive end of the third cylinder and at the other end to the adjusting support 43. A third control button is connected to the third cylinder and controls the drive end of the third cylinder to drive the third push rod 61 to push the adjusting support 43 to reciprocate along the second horizontal direction. In other words, in the spatial coordinate system, this embodiment controls the lifting cylinder 54 to drive the lifting support 53 to reciprocate along the up and down directions via the first control button, the adjusting cylinder 44 to drive the adjusting support 43 to reciprocate along the front and rear directions via the second control button, and the third cylinder drives the third push rod 61 to push the adjusting support 43 to reciprocate along the left and right directions, thereby achieving comprehensive fine-tuning of the tire 8 and assembling the tire 8 with the drive wheel axle of the car 7. After assembly, the corresponding device can be restored to its original position by operating the corresponding control button, or the device can be restored to its original position by operating the completion button in the fine-tuning device 6 with a single key operation.

The system includes: a pickup device 1, a synchronization device 2, an adjustment and support device 4, a lifting device 5, and a fine-tuning device 6. The pickup device 1 is located at the end of the tire conveyor line and is used to pick up tires 8 from the tire conveyor line and place them onto the adjustment and support device 4. The synchronization device 2 moves along the synchronous conveyor line 20 and is synchronized with the vehicle body transport 9 on the vehicle assembly conveyor 10. The lifting device 5 is mounted on the synchronization device 2, and the adjustment and support device 4 is connected to the lifting device 5. After the adjustment and support device 4 carries the tire 8, it adjusts the tire 8 to a first position along a first direction, and then adjusts the tire 8 to a second position along a second direction via the lifting device 5. The fine-tuning device 6 is mounted on the adjustment and support device 4, and when the tire 8 reaches the second position, it installs the tire 8 at a designated position on the vehicle 7.

[0053] In this embodiment, the tire 8 is automatically picked up by the picking device 1 and placed onto the positioning carrier device 4. The positioning carrier device 4 and the lifting device 5 then transport the tire 8 to the drive wheel axle position of the vehicle 7. Finally, the fine-tuning device 6 installs the tire 8 onto the drive wheel axle of the vehicle 7.
