[0031] In this invention, to address the problem that existing laser processing equipment is not adapted to efficient production rhythms during A-pillar inner panel processing, two spaced conveyor components are installed at the entrance of the processing chamber of the laser cutting machine. The A-pillar inner panel to be processed is placed on a support component, and the two conveyor components alternately feed two A-pillar inner panels into the processing chamber. While one A-pillar inner panel is being processed in the processing chamber, the operator can place the next A-pillar inner panel on the outer support component to complete the loading and positioning of the A-pillar inner panel. After the A-pillar inner panel in the processing chamber is processed, the two conveyor components work simultaneously to respectively send the processed A-pillar inner panel out and send the next A-pillar inner panel into the processing chamber. While the laser cutting machine is processing, unloading and continued loading can be completed outside the processing chamber. This design of two conveyor components and a support plate makes full use of time and improves processing efficiency.

[0032] Due to the rotating support structure, the posture of the A-pillar inner panel can be adjusted by rotating the support. A-pillar inner panels are mostly long and narrow parts. During transport, rotating the support ensures the length of the A-pillar inner panel is parallel to the transport components, preventing interference when two support components are transporting simultaneously. After transporting to the correct position, the support component in the processing chamber rotates to span the two transport components. The laser head inside the laser cutting machine moves within a certain range to process the A-pillar inner panel on both support components. This rotating support structure increases the processing space without increasing the footprint of the laser cutting machine itself, resulting in a compact and efficient structure. Aside from adding transport components, no major adjustments are needed. Modifying an existing laser cutting machine can improve the processing efficiency of A-pillar inner panels, adapting to high-paced production demands and reducing production costs for enterprises.

[0044] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0045] Reference Figure 1 For the first embodiment of the present application, a laser cutting machine for processing vehicle A-pillar inner plate is provided, comprising a laser cutting machine body 1, the laser cutting machine body 1 has a processing bin 101, the processing bin 101 has an entrance 102; two conveying members 2 are provided, the two conveying members 2 are spaced apart, one end of the conveying member 2 is located in the processing bin 101, and the other end is located outside the laser cutting machine body 1 after penetrating through the entrance 102; a supporting member 3 is rotatably arranged on the conveying member 2, the supporting member 3 is used for placing the A-pillar inner plate 4 to be processed, and the supporting member 3 is parallel to the conveying member 2 or located above the two conveying members 2 after rotation.

[0046] In the embodiment, two spaced conveying members 2 are arranged at the entrance 102 of the processing bin 101 of the laser cutting machine body 1, the A-pillar inner plate to be processed is placed on the supporting member 3, and the two conveying members 2 can alternately send two A-pillar inner plates 4 to be processed into the processing bin 101, while one A-pillar inner plate 4 is processed in the processing bin 101, the worker can place the A-pillar inner plate 4 to be processed on the supporting member 3 outside, and complete the feeding and positioning of the A-pillar inner plate 4. After the A-pillar inner plate 4 in the processing bin 101 is processed, the two conveying members 2 work simultaneously, respectively sending the processed A-pillar inner plate 4 out and sending the A-pillar inner plate 4 to be processed into the processing bin 101, while the laser cutting machine is processing, the unloading and continuous feeding work can be completed outside the processing bin 101. Through the design of the two conveying members 2 and the supporting plate, the time can be fully utilized, and the processing efficiency is improved.

[0047] Due to the rotating arrangement of the support 3, the posture of the A-pillar inner panel 4 can be adjusted by rotating the support 3. The A-pillar inner panel 4 is usually a long strip-shaped part. During the conveying process, the support 3 is rotated to make the length direction of the A-pillar inner panel 4 parallel to the conveying member 2, so as to avoid interference when two supports 3 are conveyed at the same time. After being conveyed to the position, the support 3 located in the machining cabin 101 is rotated to make the support 3 cross two conveying members 2. The laser head in the laser cutting machine body 1 can move in a range to machine the A-pillar inner panels 4 on the two supports 3. Through the rotating arrangement of the support 3, the machining position is increased without increasing the occupied area of the laser cutting machine body 1, so that the structure of the whole laser cutting machine is compact and reasonable. Except for increasing the conveying member 2, no substantial adjustment is made. Through the modification of the original laser cutting machine, the machining efficiency of the A-pillar inner panel 4 can be improved, the production demand of high rhythm is met, and the production cost of the enterprise is reduced.

[0048] Further, referring to Figures 2-3 , the support 3 comprises a rotating plate 31, the rotating plate 31 is rotatably arranged on the conveying member 2; a plurality of positioning rods 32 are arranged on both sides of the rotating plate 31, and a positioning space is formed between the plurality of positioning rods 32, the positioning space is used for placing the A-pillar inner panel 4; a plurality of support columns 33 are arranged on one end of the rotating plate 31, and the other end is used for abutting with the A-pillar inner panel 4.

[0049] In the embodiment, a plurality of positioning rods 32 are installed on both sides of the rotating plate 31. Since the A-pillar inner panel 4 is usually irregularly shaped, the number of the positioning rods 32 is preferably two. The two positioning rods 32 each have a supporting portion and a blocking portion. The supporting portion supports the lower side of the A-pillar inner panel 4, and the two blocking portions are oppositely arranged to constrain the two sides of the A-pillar inner panel 4, so as to complete the preliminary fixing of the A-pillar inner panel 4. In some embodiments, the plurality of positioning rods 32 can also be distributed around the A-pillar inner panel in the form of positioning and fixing. The positioning space surrounded by the positioning rods 32 is adapted to the contour of the A-pillar inner panel 4. Thus, the fixing of the A-pillar inner panel 4 is more stable, which helps to improve the machining quality of the A-pillar inner panel 4. A plurality of support columns 33 are also arranged on the rotating plate 31. When the A-pillar inner panel is placed in the positioning space, the support columns 33 contact and support the A-pillar inner panel to ensure the stability of the A-pillar inner panel during the machining process. The support columns 33 can also effectively support the A-pillar inner panel 4, disperse the weight of the A-pillar inner panel 4, reduce the deformation of the panel caused by improper support, further improve the machining quality and precision, and be beneficial to produce the A-pillar inner panel products meeting the strict requirements of automobile manufacturing.

[0050] Further, referring to Figure 4The bottom of the A-pillar inner plate 4 has a plurality of support rib plates 40, and the A-pillar inner plate 4 is located in the positioning space, and the support rib plates 40 are parallel to the axis of the support column 33. The support 3 further comprises a support block 34 arranged on the support column 33, and the support block 34 has a limiting groove 341. The support column 33 abuts against the A-pillar inner plate 4 through the support block 34, and the limiting groove 341 is used to accommodate the support rib plate 40.

[0051] In this embodiment, when the bottom of the A-pillar inner plate has longitudinally distributed and transversely distributed support rib plates 40, the support block 34 is mounted on the support column 33. The limiting groove 341 of the support block 34 is matched with the shape of the support rib plate 40. After the A-pillar inner plate is placed in the positioning space, the support rib plate 40 is just embedded in the corresponding limiting groove 341, so that the positioning between the A-pillar inner plate and the support 3 is more stable and accurate.

[0052] The design of the support block 34 and the limiting groove 341 thereof is targeted at the structure of the support rib plate 40 at the bottom of the A-pillar inner plate, and realizes more accurate positioning and more stable support. It can effectively prevent the A-pillar inner plate from being slightly displaced or shaken due to vibration or other external factors during processing, and ensure the accuracy of the laser cutting path, thereby improving the processing precision and quality consistency of the product and reducing the scrap rate.

[0053] Further, with reference to Figures 3-4 , the conveying direction of the conveying member 2 is defined as the longitudinal direction, and the direction perpendicular to the longitudinal direction in the horizontal plane is defined as the transverse direction. A plurality of support rib plates 40 are distributed at the bottom of the A-pillar inner plate 4 along the longitudinal direction and the transverse direction, respectively. A plurality of support columns 33 are divided into two groups along the transverse direction, and each group of support columns 33 is provided with a support block 34. One group of limiting grooves 341 is arranged along the transverse direction, and the other group of limiting grooves 341 is arranged along the longitudinal direction.

[0054] In this embodiment, the plurality of support columns 33 are divided into two groups along the transverse direction. The limiting grooves 341 of one group of support blocks 34 are arranged along the transverse direction and used to accommodate the transversely distributed support rib plates 40. The limiting grooves 341 of the other group of support blocks 34 are arranged along the longitudinal direction and used to accommodate the longitudinally distributed support rib plates 40. When placing the A-pillar inner plate, it is accurately placed according to the corresponding relationship between the support rib plates 40 and the limiting grooves 341. This way of grouping the support columns 33 and arranging the limiting grooves 341 in different directions can position and support the A-pillar inner plate in all directions. It maximizes the degree of freedom of the A-pillar inner plate during processing, further improves the processing precision, ensures that the laser cutting and other processing processes can be carried out according to the preset accurate path, and produces high-quality A-pillar inner plate products, which meet the high-precision requirements of the automobile body structure for the A-pillar inner plate.

[0055] Further, with reference to Figure 1Further, the main protective door 5 is hingedly arranged on the upper side of the entrance 102, and the observation window of the main protective door 5 is made of transparent high-strength glass material, which facilitates the operator to observe the processing situation in the processing chamber 101 from outside.

[0056] In this embodiment, the main protective door 5 is hingedly arranged on the upper side of the entrance 102 of the laser cutting machine body 1, and the observation window of the main protective door 5 is made of transparent high-strength glass material, which facilitates the operator to observe the processing situation in the processing chamber 101 from outside. The auxiliary protective door 6 is arranged on the lower side, and two accommodating grooves 61 are machined on the auxiliary protective door 6, which are matched with the cross-sectional shape of the conveying member 2 in shape and size, so that when the main protective door 5 and the auxiliary protective door 6 are swung to close the entrance 102, the protective door is tightly combined with the conveying member 2, preventing the escape of laser radiation and debris and gas generated during processing. When feeding or discharging is needed, the main protective door 5 and the auxiliary protective door 6 are swung open, and the conveying member 2 can work normally.

[0057] The observation window of the main protective door 5 facilitates the operator to monitor the processing process in real time, discovers abnormal conditions in time and adjusts, improves the safety and controllability of processing. The design of the accommodating grooves 61 of the auxiliary protective door 6 ensures the compatibility of the protective door with the conveying member 2 in the closed state, and the overall protective door structure effectively blocks the laser radiation and processing debris, protects the personal safety of the operator, and at the same time avoids the pollution of the pollutants in the processing process to the external environment, meets the safety production and environmental protection requirements, and is conducive to maintaining a good working environment.

[0058] Further, referring to Figure 3 Further, the baffle 35 is arranged at one end of the rotating plate 31, and the waste frame 7 is arranged on the rotating plate 31 in an inclined manner, and a temporary storage area 351 is formed between the waste frame 7 and the baffle 35, and the waste after cutting slides along the waste frame 7 and enters the temporary storage area 351.

[0059] In this embodiment, the baffle 35 is fixedly arranged at one end of the rotating plate 31, and the waste frame 7 is arranged on the rotating plate 31 in an inclined manner, so that the waste frame 7 is arranged in an inclined manner relative to the rotating plate 31. During the laser cutting of the A-pillar inner panel, the waste generated slides along the inclined surface of the waste frame 7 and finally enters the temporary storage area 351 for collection. The combined design of the baffle 35 and the waste frame 7 provides an effective collection and temporary storage space for cutting waste. During the processing, timely cleaning of the waste helps to keep the processing area clean, and at the same time, centralized collection of the waste facilitates subsequent unified treatment, improves the management efficiency of the processing site, and reduces the equipment failure and processing quality problems caused by untimely cleaning of the waste.

[0060] Further, referring to Figure 2The waste frame 7 has a plurality of clearance grooves 71, which are arranged in a transverse and longitudinal array on the waste frame 7, and are used to accommodate the support column 33. The waste frame 7 further comprises a gasket 8, which is used to block the clearance grooves 71.

[0061] In this embodiment, when the plurality of clearance grooves 71 are processed on the waste frame 7 in a transverse and longitudinal array, the corresponding clearance groove 71 is selected according to the position of the support column 33 before processing, the support column 33 is inserted into the clearance groove 71, and then the gasket 8 is used to block the part of the clearance groove 71 not occupied by the support column 33, so as to prevent waste from leaking out of the clearance groove 71. The use of the gasket 8 ensures the sealing of the waste frame 7, avoids waste leakage due to the existence of the clearance groove 71, ensures that the waste can be smoothly collected to the temporary storage area 351, maintains the cleanliness of the processing area, and improves the reliability and integrity of waste collection. The clearance grooves 71 can also be arranged in a long strip shape, so that even when different specifications of A-pillar inner panels 4 are processed, the position of the support column 33 can be adjusted, and the waste frame 7 can be shared when the position of the support column 33 is not adjusted much, thereby improving the versatility of the waste frame 7.

[0062] Further, with reference to Figures 5-6 , the waste frame 7 has a first long hole 72, which is used to accommodate the support column 33, and the upper end of the first long hole 72 abuts against the support column 33. The waste frame 7 further comprises a swing frame 9, which is swingably arranged at one end of the waste frame 7 close to the baffle 35. The swing frame 9 has a second long hole 91, and the lower end of the second long hole 91 abuts against the support column 33. The swing frame 9 abuts against or is away from the waste frame 7 after swinging.

[0063] In this embodiment, the first long hole 72 is processed on the waste frame 7, and the width of the first long hole 72 is matched with the diameter of the support column 33, so that the support column 33 can be inserted into the first long hole 72 and abut against the upper end of the first long hole 72. The swing frame 9 is hingedly installed at one end of the waste frame 7 close to the baffle 35, and the lower end of the second long hole 91 on the swing frame 9 abuts against the support column 33. When it is necessary to clean the waste frame 7, the swing frame 9 is swung away from the waste frame 7, and at this time, the waste frame 7 can be cleaned. When normal processing is performed, the swing frame 9 is swung back to abut against the waste frame 7. Since the first long hole 72 and the second long hole 91 are arranged in a staggered manner, waste leakage can be prevented, and the waste can slide along the surface of the swing frame 9 into the temporary storage area 351. By adding the swing frame 9, the problem that waste remains on the waste frame 7 due to friction and still needs to be cleaned manually is reduced.

[0064] Further, with reference to Figure 5 , the swing frame 9 has a through groove 92 at one end close to the baffle 35. After the swing frame 9 is swung away from the waste frame 7, the residual waste on the waste frame 7 enters the temporary storage area 351 through the through groove 92.

[0065] In this embodiment, a through slot 92 is machined on one end of the swing frame 9 close to the baffle 35. During machining, some waste material may fall on the waste frame 7 through the second long slot 91, and this part of waste material cannot fall into the temporary storage area 351 through the swing of the swing frame 9. Due to the existence of the through slot 92, after the swing frame 9 swings away from the waste frame 7, the waste material can enter the temporary storage area 351 through the through slot 92, avoiding accumulation in the waste frame 7. Since the position of the through slot 92 is close to the temporary storage area 351, the waste material on the swing frame 9 will all fall into the temporary storage area 351 or on the edge of the temporary storage area 351, which will not have a greater impact on the collection of waste material on the swing frame 9.

[0066] The design of the through slot 92 enhances the self-cleaning ability of the waste collection system, effectively preventing the accumulation and blockage of waste material in the waste frame 7. Whether in the normal machining process or when cleaning the waste frame 7, the waste material can enter the temporary storage area 351 more smoothly, improving the efficiency and reliability of waste collection, reducing the risk of equipment failure caused by waste accumulation, and ensuring the continuity and stability of laser cutting machining.

[0067] Further, with reference to Figure 1 It also includes a camera, which is arranged inside the machining chamber 101; and a display assembly 10 arranged outside the machining chamber 101, which is used to display the content captured by the camera.

[0068] In this embodiment, the camera, such as a high-definition camera, is installed at a suitable position inside the machining chamber 101, so that it can capture the situation of the machining area. The display assembly 10, such as a liquid crystal display screen, is installed outside the machining chamber 101, and the camera is connected to the display assembly 10 through a data line. During the laser cutting of the A-pillar inner panel, the camera captures the machining scene in real time, and the image data is transmitted to the display assembly 10 for display. The operator can view the machining situation through the display assembly 10 outside the machining chamber 101. The camera stores the captured machining situation, and when a machining quality problem is found, the staff can find the cause by playing back, which improves the intelligentization and automation level of the entire laser cutting machining system.

Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the present application, and they should be covered in the scope of the claims of the present application.
