Description

[0002] In the traditional laser cutting technology, when processing profiles, due to the requirement of positioning accuracy, the raw material cannot be directly cut into the required size. Instead, a part of the head is first cut off, which is usually useless and treated as waste. Then, through additional process steps, such as using positioning devices or adjusting cutting parameters, the precise positioning of the profile is realized. In this way, in order to meet the positioning requirements, the length of the raw material must be longer than the final formed size to ensure that after cutting off the head and precise positioning, the profile that meets the requirements can still be obtained.

[0003] However, the scheme adopted in the prior art removes a large amount of head, which not only causes waste of raw materials, but also increases the cutting process, making the entire production process more complex and time-consuming, thereby reducing the production efficiency to some extent, and indirectly increasing the equipment cost.

[0031] In the embodiment, the automatic feeding mechanism 3 comprises a feeding power assembly 8, front and rear arranged unloading clamping stations 9 and feeding clamping stations 10 and an adjusting assembly 11 for positioning the profile 16 on the clamping stations, the feeding power assembly 8 comprises a positioning support 17, a sliding plate is slidably arranged above the positioning support 17, the sliding plate is horizontally engaged with transmission on the positioning support 17, and a horizontal positioning frame 12 for supporting the unloading clamping stations 9 and the feeding clamping stations 10 is installed on the sliding plate. An adapter seat 13 is fixed on the sliding plate, and the horizontal positioning frame 12 is vertically engaged with transmission on the adapter seat 13; the adjusting assembly 11 comprises a support rod 38, the support rod 38 is fixed on the positioning support 17, adjusting frames are slidably installed on the two sides of the support rod 38, and two groups of the sliding frames are relatively moved to realize horizontal positioning of the profile 16. The unloading clamping stations 9 and the feeding clamping stations 10 each comprise a group of oppositely arranged clamping plates 14, one of the clamping plates 14 can be moved relative to the other clamping plate 14; and an operation table 15 is further installed on one side of the integrated frame 4.

[0032] During operation of the present application, firstly, a group of profiles 16 to be processed are placed on the loading and clamping station 10, and positioning of the profiles 16 is achieved through front and rear clamping of the clamping plates 14 and left and right clamping of the adjusting frame; the positioning support 17 is sent below the processing station in the integrated frame 4 through horizontal meshing transmission of the sliding plate, at this time, the profile 16 is below the clamping and positioning of the chuck assembly 7; the profile 16 is lifted to the clamping station of the chuck assembly 7 through vertical meshing transmission of the horizontal positioning frame 12 on the adapter seat 13; after the chuck assembly 7 clamps the profile 16, the laser cutting head 5 is driven to move according to a preset trajectory through the three-axis motion platform 6, and laser cutting processing of the profile 16 is completed; during the laser cutting processing, the loading and clamping station 10 is reset; after another profile 16 to be processed is placed on the loading and clamping station 10 and clamping positioning is completed, the unloading and clamping station 9 is moved below the processing station; the processed profile 16 falls into the unloading and clamping station 9.

[0033] The positioning support 17 is further moved forward by a distance so that the loading and clamping station is below the processing station through horizontal meshing transmission of the sliding plate on the positioning support 17; after the chuck assembly 7 clamps the profile 16, the loading and clamping station 10 is reset again, and the profile 16 that has completed laser cutting processing can be sent out of the integrated frame 4 at the same time; the profile 16 to be processed is placed on the loading and clamping station 10, and the processed profile 16 is taken out from the unloading and clamping station 9, as shown in FIG. 1, and the above operation is repeated to complete continuous laser cutting processing of the profile 16.

[0034] The present application adopts modular design, and the installation process is simpler and more convenient, which can effectively save transportation and installation costs, and the profile 16 can be quickly and accurately positioned through the automatic feeding system, without the need for cutting the material head, and continuous cutting processing of the material can be achieved, with high production efficiency.

[0035] In the embodiment, the cleaning assembly 21 comprises a supporting plate 25 and a friction belt 28, both ends of the supporting plate 25 are integrally formed with end plates 26, one of the end plates 26 is externally screwed with a first servo motor 27, the output shaft of the first servo motor 27 is wound with the friction belt 28, and the bottom of the supporting plate 25 is welded with a flow guide channel 29. The air blowing pipeline 24 is inserted into one end of the flow guide channel 29, the top of the flow guide channel 29 is provided with an air outlet 30, the middle of the air outlet 30 is inserted with a scraping strip 31, and the top of the scraping strip 31 abuts against the bottom area of the friction belt 28. Whether the plate material is warped can be detected through the multiple distance measuring modules 40 in the detection mechanism 18, and the bottom of the plate material and the surface of the clamping station can be cleaned, so that the workpiece clamped in the clamp area is prevented from being warped due to accumulation of debris, and the accuracy of subsequent laser cutting is effectively improved.

[0036] Specifically, after the profile 16 is conveyed to the inside of the cutting area 1, the detection units 22 on both sides detect the height of different positions on the bottom of the profile 16. When the detection result data is consistent, it means that the profile 16 currently in the cutting area 1 is in a horizontal state and has not been raised. When the detection units 22 on both sides detect that the height positions of the top profile 16 are different, the cleaning assembly 21 can be used to blow and clean the bottom of the profile 16 and the clamping station area. In this process, the electric lifting rod 20 is first lifted until the two friction belts 28 are abutted against the bottom area of the profile 16, and then the two servo motors are controlled synchronously to rotate the friction belts 28 towards the same side, so that the profile 16 is conveyed towards one side until the support area on the surface of the profile 16 generated by the clamping station is moved to the surface of the friction belt 28. At this time, the electric lifting rod 20 is continuously controlled to move upwards until it is abutted against the bottom of the extrusion limiting mechanism 23. The profile 16 is clamped and fixed by the extrusion limiting mechanism 23, and one of the servo motors is started to control the friction belt 28 to rotate in the opposite direction, so that only the bottom of the profile 16 is cleaned by the friction belt 28, and the profile 16 is prevented from moving.

[0037] In this process, the high-pressure airflow is blown out from the surface of the cleaning assembly 21 towards both sides through the bottom blowing pipeline 24, which blows the debris and dust adhered to the bottom of the profile 16 towards the side, and blows and cleans the clamping station area in the middle from the other direction. After cleaning, the profile 16 is reset by the two servo motors and the electric lifting rod 20.

[0038] In this embodiment, the detection unit 22 comprises a fixed guide plate 37, a movable plate 39 and a distance measuring module 40. The side edges of the fixed guide plate 37 are screwed with support rods 38. The top of the fixed guide plate 37 is attached with a clamping strip 42, and a through hole 41 is formed in the middle of the fixed guide plate 37. The bottom of the fixed guide plate 37 is screwed with a second servo motor 45. The output end of the second servo motor 45 is inserted with a drive shaft 46, and the distal end of the drive shaft 46 is screwed with a gear 47. The bottom of the movable plate 39 is provided with a clamping groove 43 which is embedded in the inside of the clamping strip 42. The clamping groove 43 and the clamping strip 42 are both in a “T” shape structure. The surface of the movable plate 39 is screwed with the distance measuring module 40, and one end of the movable plate 39 is integrally formed with a gear rack 44. The gear rack 44 is engaged with the gear 47.

[0039] The top of each fixed guide plate 37 is provided with two movable plates 39 and a distance measuring module 40, and the two distance measuring modules 40 on the same detection unit 22 always move in opposite directions, and the fixed guide plate 37 is fixedly connected with the side of the supporting plate 25 through the supporting rod 38. By means of a plurality of distance measuring modules 40, whether the distance measuring value detected by the distance measuring modules 40 on the same side changes at the same time during the conveying of the plate to the cutting area 1 can be detected, and the driving structure in the detection unit 22 is matched to check whether the width of the plate is even, thereby providing an additional detection means for the plate and ensuring that the final laser cutting product will not be unqualified due to the size difference of the plate itself.

[0040] Specifically, the height of the profiled bar 16 at the bottom of the cutting area 1 on both sides is measured by the detection units 22 on both sides, so that whether the profiled bar 16 is inclined can be judged, and during the pushing of the profiled bar 16 into the cutting area 1, the distance measuring module 40 close to the outside in each detection unit 22 will change the distance measuring value at the moment when the profiled bar 16 is moved to the top, so that the time difference of the height data detected by the two distance measuring modules 40 can be obtained, so that whether the side of the profiled bar 16 currently conveyed to the inside is flush can be judged, and at the same time, after the profiled bar 16 is conveyed into position, the second servo motor 45 at the bottom is started, and the distance measuring modules 40 on both sides are controlled to move synchronously toward the side, if the profiled bar 16 is already in the central axis region of the cutting area 1 domain, the distance measuring modules 40 on both sides will simultaneously pass the edge region of the profiled bar 16 on both sides, at this time, it can be judged that the central axis of the profiled bar 16 has been aligned with the preset central axis of the cutting area 1 domain, otherwise it proves that the profiled bar 16 on both sides is not parallel or does not reach the central axis region.

[0041] The movement process of the two distance measuring modules 40 in each detection unit 22 is that the second servo motor 45 is started, and the gear 47 cooperates with the two side racks 44 to rotate, so that the two interactive plates on both sides are pushed in different directions, and the synchronous expansion and pushing of the two distance measuring modules 40 are finally realized.

[0042] In the embodiment, the extrusion limiting mechanism 23 includes a limiting baffle 32 and a pressure receiving plate 34, the rear end of the limiting baffle 32 is integrally formed with a fixed plate 33, the top of the pressure receiving plate 34 is welded with a spring rod 36, the bottom of the pressure receiving plate 34 is attached with an anti-skid pad 35, and the top of the spring rod 36 is inserted into the inside of the limiting baffle 32.

[0043] The basic principles and main features of the present application and the advantages of the present application are shown and described above, and it is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be realized in other specific forms without departing from the spirit or essential characteristics of the present application.

[0044] Furthermore, it should be understood that although the specification is described in terms of embodiments, not every embodiment includes only one independent technical solution, and the specification is described in this way only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that those skilled in the art can understand.
