[0001] This utility model relates to the technology of automobile conveying, and in particular to an automobile rear door recycling processing line. Background Technology

[0002] In the automotive manufacturing industry, the assembly of car rear doors typically involves multiple processes, including welding, gluing, and installing components. These processes usually need to be completed at different workstations, and due to the unique structure of the car door, some processing steps may require adjusting the door's orientation to allow operators to work more efficiently.

[0003] Traditional automotive rear door conveyor lines typically use straight or circular conveyor belts to transport car doors sequentially to various workstations. However, this method has drawbacks. During assembly, certain steps may require changing the orientation of the car doors, and traditional conveyor lines lack automatic steering capabilities, usually necessitating manual intervention or additional steering mechanisms, leading to reduced production efficiency. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a circulating processing line for automobile rear doors, which solves the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a circulating processing line for automobile rear doors, used to transport and rotate workpieces for processing by operators, comprising; The first conveying assembly includes two conveying frames arranged side by side, and a placement frame that slides on them; Two sets of second conveying components are respectively located at the inlet end and outlet end of the conveying frame; each set of second conveying components includes two receiving conveying frames and a bogie located between the two; The receiving conveyor frame includes two parallel guide conveyor bars and an ejector assembly located at the lower end of the two guide conveyor bars; During operation, the workpiece is moved from one conveyor to a receiving conveyor for processing, then transferred to a bogie for turning, and then discharged to another adjacent receiving conveyor for further processing. Finally, it enters another conveyor and is conveyed to the next set of conveyor components to repeat the above process.

[0006] Furthermore, the receiving and conveying frame is provided with support frames, and two receiving frames are provided on both sides of the upper end of the support frames. Multiple rollers driven by the first driving component are provided on the receiving frames.

[0007] Furthermore, the housing is positioned between two guide conveyor bars, and the roller conveying direction is the same as the conveying direction of the conveyor frame.

[0008] Furthermore, the ejection assembly includes a receiving plate mounted on a support frame, an ejection cylinder mounted below the receiving plate, the output end of which passes through the receiving plate and is mounted with a connecting plate, the upper end of the connecting plate being connected to the lower end of the guide conveyor bar.

[0009] Furthermore, two first telescopic cylinders are provided between the receiving plate and the connecting plate, and the ejector cylinder is located between the two first telescopic cylinders.

[0010] Furthermore, a drive structure is installed below the guide conveyor bar. The drive structure includes a second drive component and a linkage component connected to the output end of the second drive component. The linkage component is connected to the transmission component on the two guide conveyor bars.

[0011] Furthermore, an extension frame is provided between the two support frames, and the bogie is mounted on the extension frame.

[0012] Furthermore, the bogie includes a plate mounted on an extension frame, with a third drive unit mounted on the lower end of the plate, and the upper end of the third drive unit extending to the upper end of the plate and mounted with a turntable.

[0024] Please refer to Figure 1-6 As shown, it illustrates the specific structure of a preferred first embodiment of the present invention, which is an automotive rear door circulating processing line for conveying and rotating workpieces for processing by operators, including: The first conveying assembly 10 includes two conveying frames 11 arranged side by side, and a placement frame 1 that slides on them; Two sets of second conveying components 20 are respectively located at the inlet end and the outlet end of the conveying frame 11; each set of second conveying components 20 includes two receiving conveying frames 21 and a bogie 22 located between the two; The receiving conveyor frame 21 includes two parallel guide conveyor bars 211 and an ejection assembly 212 located at the lower end of the two guide conveyor bars 211; During operation, the workpiece moves from a conveyor frame 11 to a receiving conveyor frame 21 for processing. It is then transferred to a bogie 22 for turning, and subsequently discharged to an adjacent receiving conveyor frame 21 for further processing. Finally, it enters another conveyor frame 11 and is conveyed to the next set of conveyor components 20, repeating the above process. Alternatively, the workpiece moves from the conveyor frame 11 of the first conveyor component 10 to the receiving conveyor frame 21 for the first processing. The ejector component 212 lifts the workpiece, causing it to detach from the guide conveyor 211, and transfers it to the bogie 22. The bogie 22 rotates the workpiece to the target angle and then conveys it to an adjacent receiving conveyor frame 21 for the second processing. After processing, the workpiece enters another conveyor frame 11 and cycles to the next set of second conveyor components 20 for the third and even fourth processing. The bogie 22 allows for workpiece angle adjustment, reducing manual intervention and improving production efficiency.

[0025] For example, the receiving conveyor frame 21 is provided with support frames 217, and two receiving frames 214 are provided on both sides of the upper end of the support frame 217. The receiving frames 214 are provided with multiple rollers 215 driven by the first driving member 216. When the placement frame 1 moves from the conveyor frame 11 to the receiving conveyor frame 21, the first driving member 216 drives the rollers 215 to rotate, and drives part of it to move onto the placement frame 1 on the rollers 215. Driven by the rollers 215, it moves from the conveyor frame 11 to the receiving conveyor frame 21 and abuts against the side wall of the receiving conveyor frame 21, so that the operator can process it.

[0026] For example, the receiving frame 214 is located between the two guide conveyor bars 211, and the conveying direction of the roller 215 is the same as the conveying direction of the conveyor frame 11. Because the receiving frame 214 is located between the two guide conveyor bars 211, the placement frame 1, which is driven by the roller 215 to move completely onto the receiving conveyor frame 21, overlaps the two guide conveyor bars 211. When the guide conveyor bars 211 are running, they can drive the placement frame 1 on them to move onto the bogie 22.

[0027] For example, the ejection assembly 212 includes a receiving plate 2121 mounted on a support frame 217. An ejection cylinder 2122 is mounted below the receiving plate 2121, and its output end passes through the receiving plate 2121 and is mounted with a connecting plate 2123. The upper end of the connecting plate 2123 is connected to the lower end of the guide conveyor bar 211. Because the placement rack 1 moved to the bogie 22 needs to turn, the part of the bogie 22 that holds the placement rack 1 needs to be positioned above the guide conveyor bar 211. When the placement rack 1 on the two guide conveyor bars 211 needs to be transferred to the bogie 22, the ejection cylinder 2122 drives the connecting plate 2123 upward, thereby pushing the guide conveyor bar 211 parallel to the upper surface of the bogie 22, so as to facilitate the placement of the placement rack 1 on the bogie 22 for turning.

[0028] For example, two first telescopic cylinders 2124 are provided between the receiving plate 2121 and the connecting plate 2123, and the ejector cylinder 2122 is located between the two first telescopic cylinders 2124. The arrangement of the first telescopic cylinders 2124 can ensure the smoothness of the ejector cylinder 2122 pushing the connecting plate 2123 upward or downward when the conveying end pushes it.

[0029] For example, a drive structure 213 is installed below the guide conveyor bar 211. The drive structure 213 includes a second drive member 2131 and a linkage member 2132 connected to the output end of the second drive member 2131. The linkage member 2132 is connected to the transmission members on the two guide conveyor bars 211. Driven by the second drive member 2131, the linkage member 2132 can drive the conveyor bars on the guide conveyor bar 211 to move, and drive the placement frame 1 on it to move.

[0030] An extension frame 218 is provided between the two support frames 217, and the bogie 22 is mounted on the extension frame 218.

[0031] For example, the bogie 22 includes a plate 221 mounted on an extension frame 218. A third drive member 222 is mounted on the lower end of the plate 221. The upper end of the third drive member 222 extends to the upper end of the plate 221 and is mounted on a turntable 223. A clamping plate 224 is provided on the upper end of the turntable 223 to restrict the movement of the placement rack 1. When the placement rack 1 is placed on the turntable 223, the turntable 223 is driven to rotate by the third drive member 222 to adjust the orientation of the placement rack 1 on the turntable 223, so as to ensure that the position of the workpiece to be processed on the placement rack 1 transferred to another receiving conveyor 21 corresponds exactly to the operator.

[0032] It should be noted that the card plate 224 can be used to increase the limiting ability of the placement rack 1 placed on the turntable 223.

[0033] For example, a second telescopic cylinder 2171 is installed on the extension frame 218, and the telescopic end of the second telescopic cylinder 2171 faces upward and is equipped with an abutment block 2172. The abutment block 2172 is located below the placement frame 1. In order to prevent the placement frame 1 on the turntable 223 from shifting under the action of centrifugal force during the rotation of the turntable 223, the abutment block 2172 is driven by the second telescopic cylinder 2171 to move upward and abut against the lower end of the placement frame 1, thereby limiting the position of the placement frame 1 and maintaining the stability of the placement frame 1 when turning.

[0034] For example, the lower end of the placement rack 1 is provided with a step 1a, and the side edge of the abutment block 2172 matches the step 1a. The contact between the step 1a and the abutment block 2172 on the placement rack 1 further increases the stability of the placement rack 1 after the abutment block 2172 contacts the step 1a.

[0035] In summary, the key design feature of this utility model is that the first conveying assembly 10 conveys the placement frame 1 along the conveying frame 11 to the first receiving conveying frame 21. The roller 215 rotates under the drive of the driving component 216, and the auxiliary placement frame 1 completely enters the receiving conveying frame 21 and is positioned against the side wall for the operator to process for the first time. After processing is completed, the ejection assembly 212 is activated: the ejection cylinder 2122 pushes the connecting plate 2123 to rise, so that the guide conveyor bar 211 is raised to be flush with the bogie 22, and the drive structure 213 drives the guide conveyor bar 211 to move and move the placement frame 1 to the turntable 223 of the bogie 22. The third driving component 222 drives the turntable 223 to rotate, adjusts the angle of the placement rack 1, so that the workpiece surface to be processed faces the next station, and the second telescopic cylinder 2171 pushes the abutment block 2172 to move upward and lock into the step 1a of the placement rack 1 to prevent deviation when turning. After the turn is completed, the ejector assembly 212 raises the guide conveyor 211 again, so that the placement frame 1 moves from the turn frame 22 to the second receiving conveyor frame 21. The operator performs the second processing. After the processing is completed, the placement frame 1 returns to the conveyor frame 11 and enters the next set of second conveyor assembly 20 for cyclic processing. The workpiece circulates between the two sets of second conveyor components 20, and each time the angle is adjusted by the bogie 22 to ensure that different processing surfaces face the operator until all processes are completed.

[0036] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
