Description

Technical Field

[0001] This utility model relates to the field of automobile roof production technology, and in particular to an automatic cutting and feeding device for automobile roof production. Background Technology

[0002] The car roof is an important part of the car's interior, with multiple functions and uses. During the production and processing of the car roof, the opening of the sunroof needs to be flanged. In order to ensure the quality of the flanging, the PU foam at the sunroof opening of the car roof needs to be cut to make room for the flanging. After the cutting work is completed, the cut car roof needs to be sent to the next process for processing using a feeding device.

[0003] Publication No. CN119389803B discloses an automatic cutting and feeding device for automobile headliner production. The device includes a frame with multiple drive rollers mounted on it. A base is fixedly connected to one side of the frame, and a robotic arm is mounted on the base. A laser cutting head is attached to the end of the robotic arm. The frame also includes a lifting and placing mechanism for stacking the cut automobile headliners. This invention utilizes the lifting and placing mechanism to allow multiple cut automobile headliners to be stacked before feeding, enabling them to reach subsequent processing steps simultaneously. This improves the efficiency of subsequent automobile headliner processing and the efficiency of inter-process connections.

[0004] In existing patented technologies, a laser cutting head is used to automatically cut and feed automotive headliner material conveyed on the surface of a drive roller at the frame. In such a frame, two fixed plates driven by electric push rods are used to clamp the automotive headliner material for stable cutting during automatic feeding. However, this simple clamping structure has limited stability for holding the automotive headliner above the drive roller, making it easy for the automotive headliner material to be suspended and cut above the drive roller, resulting in collapse and deformation of the automotive headliner material during cutting. Therefore, we propose an automatic cutting and feeding device for automotive headliner production. Utility Model Content

[0005] The main objective of this invention is to provide an automatic cutting and feeding device for automobile roof production. By incorporating a supporting cutting mechanism into the frame of existing patented automatic cutting and feeding devices, the main push rod of the supporting cutting mechanism drives the clamping plate to initially clamp the automobile roof material. Simultaneously, the auxiliary push rod, through the corner connecting plate, drives the pressure plate below the guide plate to press vertically downwards, tightly pressing the automobile roof material against the surface of the drive roller and the T-shaped connecting plate. The sliding fit between the T-shaped connecting plate and the grooved connecting plate forms a bottom support surface, effectively eliminating areas where the material is suspended and preventing damage to the automobile roof material. Compared to traditional clamping structures, this design significantly improves clamping stability, preventing collapse and deformation caused by insufficient support during roof material cutting. Furthermore, the U-shaped fit design of the guide plate and guide groove ensures vertical guiding accuracy when the pressure plate is pressed down, resulting in uniform material stress. The interconnected structure of the connecting column guide groove and the guide groove further guarantees smooth guiding of the pressure plate's lifting and lowering. When the laser cutting head is operating, the automotive roof material is stably fixed to the supporting surface, improving cutting accuracy and reducing waste caused by deformation. Balancing efficiency and processing quality, this design effectively solves the problems mentioned in the background technology.

[0012] Furthermore, a side strip hole plate is welded to one side of the cylinder body of the auxiliary push rod, and the side strip hole plate is locked to the top of the clamping plate by bolts. A bolt is screwed from bottom to top between the telescopic rod head of the auxiliary push rod and the corner plate of the horn connecting plate.

[0014] Furthermore, the guide groove has a U-shaped cavity, and a U-shaped plate with a guide plate is slidably inserted into the U-shaped cavity of the guide groove.

[0015] By adopting the above technical solution, the U-shaped cavity of the guide groove can be adapted to the U-shaped plate of the guide plate for guiding and sliding.

[0016] Furthermore, the bottom end of the clamping plate is welded with a T-shaped connecting plate through a series of connecting columns, and the column body of the connecting column is provided with a guide groove that is vertically connected to the guide groove.

The side of the clamping plate 7 away from the guide rods 8 is vertically provided with guide grooves 9 for clamping the guide plate 10. The upper and lower ends of the guide plate 10 are respectively welded with corner connecting plates 12 and pressure plates 11. The plate body of the corner connecting plates 12 is clamped on the outside of the vertical plate body of the clamping plate 7. The telescopic rod heads of the auxiliary push rods 13 are locked to the corner plates at both ends of the corner connecting plates 12 by bolts.

[0030] By adopting the above technical solution, the main push rod 6 is installed after the surface plate of the main push rod 6 is locked to the back of the three-hole fixed plate 3 with bolts. Then, the telescopic rod head of the main push rod 6 is locked to the clamping plate 7 with a long connecting plate and bolts, thereby facilitating the driving of the clamping plate 7 to perform the action.

[0031] The auxiliary push rod 13 has a side strip hole plate welded to one side of its cylinder body, and the side strip hole plate is locked to the top of the clamping plate 7 by bolts.

After welding a three-hole fixed plate 3 above the frame 1, a grooved connecting plate 4 is welded between the frame 1 and the three-hole fixed plate 3. The main push rod 6 of the cutting support mechanism 5 is then installed by bolting the grooved plate to the back of the three-hole fixed plate 3. The telescopic head of the main push rod 6 is then locked to the clamping plate 7 with a long connecting plate and bolts. The guide rod 8 on the back of the clamping plate 7 can extend after passing through the three-hole fixed plate 3. Then, the corner connecting plate 12 is guided and clamped at the guide groove 9 of the clamping plate 7 by the guide plate 10.

As the car roof material is placed on the surface of the transmission roller 2 and moved to the surface of the T-shaped connecting plate 15 above the groove connecting plate 4, the main push rod 6 extends a telescopic rod to push the clamping plate 7 towards the car roof material for clamping. Then, the auxiliary push rod 13 pushes the corner connecting plate 12 to descend. The corner connecting plate 12 is guided by the guide plate 10 at the guide groove 9 to descend, so that the pressure plate 11 below the guide plate 10 presses the car roof material on the stopped transmission roller 2 and the surface of the T-shaped connecting plate 15. After stable pressing, a laser cutting head is installed above the frame 1 to cut the pressed car roof material. During cutting, the pressed car roof material is less prone to collapse and deformation caused by suspended cutting. After the car roof material is cut, the auxiliary push rod 13 can lift the pressure plate 11 away from the car roof material. At the same time, the main push rod 6 can pull back the clamping plate 7 to release the car roof material. Then, the transmission roller 2 at the frame 1 can rotate normally to transport the car roof material backward, making it convenient for workers to pick it up for subsequent processing.
