Abstract
Description
Technical Field
[0001] This invention belongs to the field of decorative painting frame processing technology, and specifically discloses an automated corner cutting machine and method for frame processing. Background Technology
[0002] In the manufacturing process of decorative painting frames, corner cutting is one of the key processes. Its precision and quality directly determine the splicing effect and aesthetics of the finished frame. This requirement is particularly stringent for frames made of metal materials such as aluminum alloy. The traditional method of using mechanical saw blades for corner cutting is prone to burrs, curling, or even slight deformation at the cut edges. These defects not only affect the aesthetics but also directly lead to difficulties in installing corner brackets and a decrease in the splicing strength of the corners. To address this, laser corner cutting technology has been gradually introduced into existing technologies. It uses a high-energy laser beam to melt and cut the frame material, which has significant advantages such as smooth cuts, no burrs, no tool wear, and high processing flexibility. It is especially suitable for frame materials such as aluminum alloy.
[0003] In current automated laser corner cutting equipment, long rods are typically fixed in place, and then a laser cutting head moves along their length to cut them sequentially, dividing the long rod into multiple frame strips with beveled ends. However, during this process, the cut frame strips fall directly downwards under gravity or are simply guided into a collection box. This free-fall method has obvious defects. The falling frame strips, with their precise beveled ends, are very prone to colliding with other parts of the equipment or with each other, resulting in dents, deformation, and other damage to the cut edges. This damage will prevent the corners from being tightly aligned during subsequent frame assembly, creating visible gaps and becoming a fatal flaw affecting the product's aesthetics, leading to a higher product scrap rate.

[0008] Preferably, the upper ends of the two hydraulic cylinders extend through to the upper ends of the two mounting blocks respectively. The cross-sectional shape of the lifting plate is L-shaped. A stabilizing block is connected to one side of the lifting plate. A stabilizing groove is opened on one side of the connecting box corresponding to the two stabilizing blocks. The two stabilizing blocks slide inside the two stabilizing grooves respectively.
[0009] Preferably, a support cylinder is rotatably connected to one side of the upper end of the lifting plate, and one end of each of the two support cylinders is rotatably connected to one side of the lower end of the L-shaped transfer plate.

[0010] Preferably, there are two sets of fixing blocks. One end of each fixing block is connected to one side of the L-shaped transfer plate. One side of one fixing block is connected to a drive motor. The output end of the drive motor is connected to a drive screw. One end of the drive screw passes through one fixing block and is rotatably connected to one side of the other fixing block.

The two adjusting blocks slide along the outer wall of the sliding rod. The upper end of one adjusting block and the lower end of the other adjusting block are rotatably connected to adjusting rods.

[0011] Preferably, the lower ends of the C-shaped plate are connected to limit rods on both sides, and the lower ends of the two limit rods extend through to the lower end of the L-shaped transfer plate.

The plurality of pulleys are connected by a transmission belt.
[0012] An automated chamfering method for mirror frame manufacturing includes the following steps: S1: Place the long rod profile of the mirror frame, which is a long rod profile workpiece, on the workpiece conveying mechanism, start the equipment, drive the roller to rotate, drive the long rod profile workpiece to be conveyed forward, the workpiece passes through the central area of the processing plate 4, and the outer wall of the workpiece is clamped from the circumference by the sliding clamping roller. At the same time, the electric telescopic rod moves, driving the mounting plate and the drive roller to move in opposite directions, clamping or releasing the workpiece from the upper and lower sides, and cooperating with the clamping roller to achieve the centering and stable support of the workpiece. S2: Before laser cutting, the hydraulic cylinder drives the lifting plate to rise, so that the L-shaped transfer plate is pre-lifted to directly below the cutting point. After cutting, the long rod profile workpiece falls directly above the L-shaped transfer plate. Then the L-shaped transfer plate descends, and the support cylinder drives it to flip slightly upward, so that the workpiece moves towards the guide roller. The drive motor then finely adjusts the position of the C-shaped plate to make the workpiece stable in the center on the plate. S3: After the position adjustment is completed, the connecting motor is started, driving the guide roller to rotate and slightly conveying the long rod profile workpiece on the L-shaped transfer plate, so that its suspended end is fully supported. Then, the hydraulic cylinder drives the transfer mechanism to descend, so that the outlet end of the L-shaped transfer plate is aligned with the top of the conveyor belt. The support cylinder retracts, driving the L-shaped transfer plate to flip downward. At the same time, the drive motor drives the C-shaped plate to move towards the conveyor belt, using the guide roller to smoothly push the long rod profile workpiece onto the conveyor belt, and finally complete the output.
[0013] Compared with the prior art, the present invention has the following beneficial effects: By controlling the hydraulic cylinder to drive the lifting plate to rise before cutting, the L-shaped transfer plate is precisely pre-positioned directly below the cutting point, achieving zero-drop reception of long rod profile workpieces after cutting. This eliminates the possibility of dents, micro-deformation, or chipping on the cut corner end face due to falling impact, ensuring the integrity of the product's initial state.
[0014] After receiving the long profile workpiece, the L-shaped transfer plate is slightly tilted upward by the support cylinder, so that the long profile workpiece automatically moves towards the guide roller under the action of gravity. Then, the drive motor adjusts the position of the C-shaped plate to precisely adjust the long profile workpiece to a stable, centered position on the transfer plate. At the same time, multiple guide rollers drive the long profile workpiece to move above the transfer plate through friction, ensuring that the suspended end of the long profile workpiece is completely supported. This ensures that the long profile workpiece does not shake during subsequent transfer, laying the foundation for smooth unloading.
[0015] During unloading, the L-shaped transfer plate flips downwards, simultaneously driving the C-shaped plate to move towards the conveyor belt. Guide rollers smoothly push the long profile workpiece onto the conveyor belt, achieving a seamless and smooth transition of the long profile workpiece from the transfer plate to the conveyor belt. This avoids the risk of collision caused by the long profile workpiece rolling or slipping during the handover, ensuring the final quality of the product. Attached Figure Description

[0022] like Figure 2 and Figure 4 As shown: The pallet 15 is L-shaped. Conveying rollers are rotatably connected between one side of the pallet 15 and the other side of the connecting box 14.

[0023] like Figures 4-9 As shown: The upper ends of two hydraulic cylinders 20 extend through to the upper ends of two mounting blocks 19 respectively. The lifting plate 21 has an L-shaped cross-section. A stabilizing block 22 is connected to one side of the lifting plate 21. A stabilizing groove 23 is provided on one side of the connecting box 14 corresponding to the two stabilizing blocks 22. The two stabilizing blocks 22 slide inside the two stabilizing grooves 23 respectively. A support cylinder 26 is rotatably connected to the upper side of the lifting plate 21. One end of the two support cylinders 26 is rotatably connected to the lower side of the L-shaped transfer plate 25 respectively. Both sides of the lifting plate 21 are connected to... Guide rods 27 and L-shaped transfer plates 25 are each connected to two connecting sliders 28 on both sides of the guide rods 27. Guide grooves 29 are provided on each of the two guide rods 27 corresponding to the two connecting sliders 28. The two connecting sliders 28 are located inside the two guide grooves 29. There are two sets of fixing blocks 30. One end of each fixing block 30 is connected to one side of the L-shaped transfer plate 25. One side of one fixing block 30 is connected to a drive motor 31. The output end of the drive motor 31 is connected to a drive screw 32, one end of which passes through the L-shaped transfer plate 25. One fixed block 30 is rotatably connected to one side of the other fixed block 30. Adjusting blocks 33 are threaded onto both sides of the outer wall of the drive screw 32. A sliding rod connects the two fixed blocks 30, and the two adjusting blocks 33 slide along the outer wall of the sliding rod.

A connecting motor 39 is connected to one of the rotating rods 38 at the upper end of the C-shaped plate 35. The output end of the connecting motor 39 is connected to the upper end of the corresponding rotating rod 38. The outer wall of the guide roller 40 is made of flexible material.

[0024] The material support mechanism enables precise adjustment and stable conveying of the long rod profile workpiece 8. The fixed block 30 provides the mounting position for the drive motor 31 and the drive screw 32. The drive motor 31 drives the drive screw 32 to rotate. The drive screw 32 is a bidirectional threaded screw that can drive two adjusting blocks 33 to slide in opposite directions. The drive screw 32 is used to convert rotational motion into linear motion. The adjusting blocks 33 are used to drive the adjusting rod 34 to move.

Limiting rod 36 and limiting groove 37 are used to limit the movement trajectory of C-shaped plate 35. Rotating rod 38 is used to install and drive guide roller 40. Connecting motor 39 can provide driving power for guide roller 40. Guide roller 40 is used to contact and transport long rod profile workpiece 8. Friction is generated between guide roller 40 and one side of long rod profile workpiece 8, causing it to slide above L-shaped transfer plate 25. Pulley 41 and transmission belt 42 are used to realize synchronous transmission of multiple guide rollers 40.
[0025] An automated chamfering method for mirror frame manufacturing includes the following steps: S1: Place the long rod profile of the mirror frame, which is the long rod profile workpiece 8, on the workpiece conveying mechanism, start the equipment, drive the roller 13 to rotate, and drive the long rod profile workpiece 8 to be conveyed forward. The workpiece passes through the central area of the processing plate 4 and is clamped from the circumferential outer wall by the sliding clamping roller 7. At the same time, the electric telescopic rod 11 moves, driving the mounting plate 12 and the drive roller 13 to move towards or away from each other, clamping or releasing the workpiece from the upper and lower sides, and cooperating with the clamping roller 7 to achieve the centering and stable support of the workpiece. S2: Before laser cutting, hydraulic cylinder 20 drives lifting plate 21 to rise, so that L-shaped transfer plate 25 is pre-lifted to directly below the cutting point. After cutting, long rod profile workpiece 8 falls directly above L-shaped transfer plate 25. Then L-shaped transfer plate 25 descends, and support cylinder 26 drives it to flip slightly upward, so that the workpiece moves towards guide roller 40. Drive motor 31 then finely adjusts the position of C-shaped plate 35 so that the workpiece is centered and stable on the plate. S3: After the position adjustment is completed, the connecting motor 39 starts and drives the guide roller 40 to rotate, slightly conveying the long rod profile workpiece 8 on the L-shaped transfer plate 25, so that its suspended end is fully supported. Then, the hydraulic cylinder 20 drives the transfer mechanism to descend, so that the outlet end of the L-shaped transfer plate 25 is aligned with the top of the conveyor belt 16. The support cylinder 26 retracts, driving the L-shaped transfer plate 25 to flip downward. At the same time, the drive motor 31 drives the C-shaped plate 35 to move towards the conveyor belt 16, and uses the guide roller 40 to smoothly push the long rod profile workpiece 8 onto the conveyor belt 16, finally completing the output.
[0026] Working principle: During use, the long rod profile workpiece 8 is placed inside the conveying mechanism. To ensure stability during processing, the outer wall of the long rod profile workpiece 8 contacts multiple clamping rollers 7 as it passes through the processing disc 4. These clamping rollers 7 achieve precise position adjustment through the automatic sliding of the moving block 6 within the connecting groove 5, forming a multi-point adaptive circumferential support for the long rod profile workpiece 8. At the same time, the electric telescopic rod 11 precisely controls the upper and lower sets of mounting plates 12 to move in opposite directions, so that the drive roller 13 firmly clamps the workpiece from the vertical direction. This clamping method, which combines electric control of circumferential positioning with vertical coordination, effectively eliminates vibration and displacement of the workpiece during processing. After the equipment is started, the drive roller 13 on the mounting plate 12 rotates under the drive of the conveying motor, providing forward power for the workpiece.
[0027] After the workpiece is fixed in place, the laser cutting equipment 10 moves precisely on the moving slide rail 9 set by the corresponding moving slider. The high-energy laser beam performs non-contact melting and cutting on the long rod profile workpiece 8, completing the precise bevel processing. The non-contact characteristics of laser cutting, combined with the precise positioning of the electric control slide rail, ensure that the cut is flat, smooth and dimensionally accurate.
[0028] Before laser cutting, the hydraulic cylinder 20 drives the lifting plate 21 to rise. The sliding cooperation between the stabilizing block 22 and the stabilizing groove 23 ensures a smooth lifting process, and finally the L-shaped transfer plate 25 is accurately positioned directly below the cutting point, achieving zero-drop reception of the long rod profile workpiece 8 after it is cut.
[0029] After receiving the workpiece, the transfer mechanism first descends to a safe height. Then, the support cylinder 26 extends and retracts, pushing the L-shaped transfer plate 25 to rotate slightly upward around the rotating block 24. This rotation motion is kept stable by the cooperation of the connecting slider 28 and the guide groove 29. Under the action of gravity, the long rod profile workpiece 8 tilts towards the guide roller 40 and makes contact. The drive motor 31 then starts, driving the drive screw 32 to rotate, which drives the two adjusting blocks 33 to move along the slide bar. Through the adjusting rod 34, the C-shaped plate 35 is pushed to move along the constraint direction of the limiting rod 36 and the limiting groove 37, thereby finely adjusting the long rod profile workpiece 8 on the L-shaped transfer plate 25 to a stable central position.
[0030] After the workpiece position is adjusted, the connecting motor 39 is started. Through the transmission of the pulley 41 and the transmission belt 42, all the rotating rods 38 and the flexible guide rollers 40 are driven to rotate synchronously, and the workpiece is slightly conveyed on the plate surface to ensure that its suspended end is fully supported. Then, the hydraulic cylinder 20 drives the entire mechanism to descend, so that one side of the L-shaped transfer plate 25 is aligned with the top of the conveyor belt 16. When unloading, the support cylinder 26 retracts and drives the L-shaped transfer plate 25 to flip downward.
