Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically to a self-cleaning and online visual inspection module for a three-dimensional laser cutting system. Background Technology

[0002] Please refer to the Chinese utility model patent with publication number CN219310399U. Existing 3D laser cutting machines typically use a single-degree-of-freedom sliding loading and unloading or rotating loading and unloading method for the slide module. This cannot be combined with the crossbeam module to achieve a redundant processing mode with multiple degrees of freedom, which limits the efficiency, flexibility and processing accuracy of laser cutting, especially making it difficult to perform cutting processing on complex surfaces.

[0003] Furthermore, the waste generated by existing 3D laser cutting machines (3D laser cutting machines are mainly used for hole drilling and edge trimming; therefore, the waste from hole drilling is usually circular metal sheets, and the waste from edge trimming is usually strip-shaped metal sheets) is mostly cleaned manually by stopping the machine and cleaning the slide, which is very inefficient. Therefore, some 3D laser cutting machines have added a self-cleaning mechanism for the slide, which has improved production efficiency to some extent.

[0004] Currently, after laser cutting, the processing quality of most workpieces is inspected manually using gauges after they come off the production line, which is inefficient. Therefore, please refer to Chinese Utility Model Patent Publication No. CN219785648U, where some devices incorporate a vision camera for online workpiece inspection, improving inspection efficiency and accuracy.

[0005] For existing 3D laser cutting machines, self-cleaning of the slide and online visual inspection of the workpiece are performed in two separate processes, resulting in consistently low overall efficiency in workpiece processing.

[0006] Solving these problems is now a top priority. Utility Model Content

[0007] In view of this, the present invention provides a self-cleaning and online visual inspection module for a three-dimensional laser cutting system.

[0008] The technical solution is as follows:

[0009] The first aspect of this application relates to a self-cleaning and online visual inspection module for a three-dimensional laser cutting system, including a bed side frame and a track slide conveying mechanism. The track slide conveying mechanism includes a slide track and a slide that can move along the length of the slide track under the drive of a slide drive assembly. The bed side frame includes two vertical columns arranged on the same side of the slide track and a main beam horizontally fixedly installed on the top of the two columns. A waste collection box is arranged below the main beam. A positioning fixture that can move along the width of the slide track under the drive of a fixture translation assembly is installed on the slide. The fixture translation assembly includes a fixture base fixedly installed on the slide and a fixture translation module for driving the positioning fixture to move along the width of the slide track on the fixture base. At least one waste removal mechanism for removing waste located on the upper surface of the fixture base to the waste collection box is synchronously connected to the positioning fixture. A visual inspection assembly located directly above the waste collection box is installed on the main beam.

[0010] The self-cleaning and online visual inspection modules of the above-mentioned 3D laser cutting system provide two online adjustable degrees of freedom in the horizontal direction. Combined with the multiple degrees of freedom achieved on the crossbeam module, this enables redundant processing modes with multiple degrees of freedom. This allows for more efficient and flexible laser cutting, making it suitable for cutting more complex surfaces and achieving higher processing accuracy. Furthermore, when online visual inspection of the workpiece is required, the positioning fixture moves along the width of the slide track to directly below the visual inspection component. Simultaneously, the positioning fixture drives the waste removal mechanism to remove waste from the fixture base into the waste collection box. This completes two processes in one step, significantly improving processing efficiency. The mechanical structure is ingeniously designed and highly integrated.

[0011] In some embodiments, the vision inspection assembly includes a camera base fixedly mounted on the main beam, a sixth linear guide rail and a sixth rack both fixedly mounted on the camera base along the length of the main beam, a camera mounting base mounted on a slider of the sixth linear guide rail, and a sixth motor and a vision camera both fixedly mounted on the camera mounting base. The lens of the vision camera faces downward, and a sixth drive gear that meshes with the sixth rack is synchronously mounted on the motor shaft of the sixth motor.

[0012] In some embodiments, a light bar extending along the length of the main beam is installed at the bottom of the camera base. The light bar is located on the side of the sixth linear guide rail away from the sixth rack. A wire harness guide limiting hole is also provided on the camera base, which is located between the light bar and the sixth linear guide rail.

[0013] In some embodiments, the camera base includes a base body fixedly connected to the main beam, a vertical mounting plate extending downward from the outer edge of the base body away from the slide rail, and a horizontal mounting plate extending horizontally away from the lower edge of the vertical mounting plate in a direction away from the slide rail. The sixth rack is fixedly mounted on the side of the vertical mounting plate near the slide rail. The light bar and the sixth linear guide rail are both mounted on the bottom surface of the horizontal mounting plate. The wire harness guide limiting hole is opened on the horizontal mounting plate. Multiple reinforcing thin plates are connected between the vertical mounting plate and the horizontal mounting plate.

[0014] In some embodiments, the tooling base includes a receiving plate fixedly mounted on the slide table and two guide rail mounting brackets. The two guide rail mounting brackets are mounted opposite each other on both sides of the receiving plate along the length of the slide table track. The tooling translation module includes a fourth linear guide rail mounted on one of the guide rail mounting brackets and a fourth linear guide rail and a fourth rack mounted on the other guide rail mounting bracket. The fourth rack and the fourth linear guide rail both extend along the width of the slide table track.

The waste removal mechanism includes a connecting component installed on the corresponding active slide or driven slide and a removal component for removing waste from the corresponding receiving groove and transferring it to the waste collection box.

[0016] In some embodiments, the bottom of the receiving groove is recessed to form multiple parallel guide slots that penetrate the receiving plate along the width direction of the slide rail. The rejection assembly includes a push-pull shaft extending along the length direction of the slide rail, rejection push blocks slidably installed in the guide slots, and push-pull cranks hinged to the same end of each rejection push block. The end of each push-pull crank away from the rejection push block is hinged to the corresponding push-pull shaft. The connecting assembly includes a push-pull plate fixedly connected to the corresponding active slide or driven slide, and a push-pull connecting rod hinged to the corresponding push-pull plate. The end of each push-pull connecting rod away from the push-pull plate is hinged to the corresponding push-pull shaft.

[0017] In some embodiments, the two side walls of the guide slot are mirrored, and the guide slot consists of inclined sections and vertical sections distributed from bottom to top.

[0018] In the same feed seam: both inclined sections are inclined plane structures, and the distance between the two inclined sections gradually increases towards the bottom of the trough; both vertical sections are vertical plane structures.

[0020] In some implementations, in the same receiving trough, each guide slot is synchronously and differently inclined downwards from one end of each material ejector block near the push-pull shaft to the other end.

[0031] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0032] like Figure 1 and Figure 2 As shown, a self-cleaning and online visual inspection module of a three-dimensional laser cutting system mainly includes a bed side frame and a track slide conveyor mechanism 17.

[0033] The bed side frame includes two vertical columns 12a mounted on the same side of the slide rail 17a and a main beam 12b1 horizontally fixed on top of the two columns 12a. The main beam 12b1 and the two columns 12a together form a gantry structure. A waste collection box 25 is located below the main beam 12b1, and a vision inspection component 26 is installed on the main beam 12b1. The vision inspection component 26 is located directly above the waste collection box 25. The vision inspection component 26 is used to visually inspect the laser-cut workpiece, and the waste collection box 25 is used to collect waste.

[0034] Please see Figure 1 and Figure 6The vision inspection component 26 includes a camera base 26a fixedly mounted on the main beam 12b1, a sixth linear guide rail 26b and a sixth rack 26c fixedly mounted on the camera base 26a along the length of the main beam 12b1, a camera mounting seat 26d mounted on the slider of the sixth linear guide rail 26b, and a sixth motor 26e and a vision camera 26f fixedly mounted on the camera mounting seat 26d. The lens of the vision camera 26f faces downward. The motor shaft of the sixth motor 26e is synchronously fitted with a sixth drive gear 26g that meshes with the sixth rack 26c.

[0035] Therefore, the motor shaft of the sixth motor 26e drives the sixth drive gear 26g to rotate in both directions, thereby causing the camera mount 26d to translate. This allows for flexible adjustment of the position of the vision camera 26f, adapting to workpieces with large dimensions and complex surface structures, and achieving high control precision. Furthermore, the sixth motor 26e is preferably a servo motor, which further enhances the adjustment precision of the vision camera 26f's position.

[0036] A light bar 26h extending along the length of the main beam 12b1 is installed at the bottom of the camera base 26a. The light bar 26h is located on the side of the sixth linear guide 26b away from the sixth rack 26c, thereby providing sufficient light source for the visual camera 26f to capture images and ensuring the quality of visual inspection.

[0037] The camera base 26a is also provided with a wire harness guide and limit hole 26a1, which is located between the light strip 26h and the sixth linear guide rail 26b, so as to guide the wire harness and fiber and avoid problems such as wire harness entanglement.

[0038] Furthermore, a wiring harness limiting hole 26d1 is also provided on the camera mounting base 26d to reliably limit the wiring harness connecting the vision camera 26f and the sixth motor 26e.

[0039] In this embodiment, the camera base 26a includes a base body 26a2 fixedly connected to the main beam 12b1, a vertical mounting plate 26a3 extending downward from the outer edge of the base body 26a2 away from the slide rail 17a, and a horizontal mounting plate 26a4 extending horizontally from the lower edge of the vertical mounting plate 26a3 away from the slide rail 17a. The sixth rack 26c is fixedly installed on the side of the vertical mounting plate 26a3 near the slide rail 17a. The light bar 26h and the sixth linear guide rail 26b are both installed on the bottom surface of the horizontal mounting plate 26a4, thereby ensuring the reliable installation of the sixth rack 26c, the light bar 26h, and the sixth linear guide rail 26b. The wire harness guide limiting hole 26a1 is opened on the horizontal mounting plate 26a4. Multiple reinforcing thin plates 26a5 are connected between the vertical mounting plate 26a3 and the horizontal mounting plate 26a4, improving the structural strength between the vertical mounting plate 26a3 and the horizontal mounting plate 26a4.

[0040] Furthermore, the base body 26a2 has an inverted "T" shaped structure, which is fixed to the main beam 12b1 by multiple bolts, ensuring the stability and reliability of the installation, thereby ensuring the quality of visual inspection.

[0041] Please see Figures 1-5 The track slide conveyor mechanism 17 includes a slide track 17a and a slide 17b that can move along the length of the slide track 17a under the drive of the slide drive assembly. Typically, the slide track 17a extends along the X-axis.

[0042] The slide table 17b is equipped with a positioning fixture 18 that can move along the width direction of the slide table track 17a under the drive of the fixture translation component 19.

[0043] The tooling translation assembly 19 includes a tooling base 19a fixedly installed on the corresponding slide table 17b and a tooling translation module for driving the positioning tooling 18 to move along the width direction of the slide table track 17a on the tooling base 19a. At least one waste removal mechanism 24 for removing waste located on the upper surface of the tooling base 19a to the waste collection box 25 is synchronously connected to the positioning tooling 18.

[0044] Therefore, the slide module in this embodiment can provide two online adjustable degrees of freedom in the horizontal direction. Combined with the multiple degrees of freedom realized on the crossbeam module, it can realize a redundant processing mode with multiple degrees of freedom. This allows for more efficient and flexible laser cutting, enabling it to be applied to the cutting of more complex surfaces and achieving higher processing accuracy. Furthermore, when online visual inspection of the workpiece is required, the positioning fixture 18 moves along the width direction of the slide track 17a to directly below the visual inspection component 26. At the same time, the positioning fixture 18 simultaneously drives the waste removal mechanism 24 to remove the waste on the fixture base 18 into the waste collection box 25. This completes two steps in one step. That is, each time the positioning fixture 18 transfers the workpiece to be inspected to directly below the visual inspection component 26, the waste removal mechanism 24 simultaneously removes the waste on the fixture base 18 into the waste collection box 25. This not only greatly improves processing efficiency but also features a clever mechanical structure design and a high degree of integration. Especially for round metal sheets, they can be rolled out of the slide by their own inertia with just a slight push. This is not only efficient but also has little impact on the production cycle. However, for strip metal sheets, the working stroke of the scrap removal mechanism 24 needs to cover the tooling base 19a as much as possible.

[0045] The tooling base 19a includes a receiving plate 19a1 and two guide rail mounting brackets 19a2, both of which are fixedly installed on the corresponding slide table 17b. The two guide rail mounting brackets 19a2 are installed opposite each other on both sides of the receiving plate 19a1 along the length of the slide table track 17a. The two guide rail mounting brackets 19a2 are preferably fixedly installed on the slide table 17b and fixedly connected to the receiving plate 19a1, ensuring the stability and reliability of the tooling base 19a.

[0046] The tooling translation module includes a fourth linear guide rail 19c mounted on one of the guide rail mounting brackets 19a2, and a fourth linear guide rail 19c and a fourth rack 19b mounted on the other guide rail mounting bracket 19a2. Both the fourth rack 19b and the fourth linear guide rail 19c extend along the width direction of the slide rail 17a. The positioning tooling 18 includes an active slide 18a and a driven slide 18b on both sides of the receiving plate 19a1. The active slide 18a and the driven slide 18b are respectively fixedly mounted on the sliders of the corresponding fourth linear guide rails 19c. A fourth motor 19d is mounted on the active slide 18a, and a fourth drive gear 19e that meshes with the fourth rack 19b is synchronously mounted on the motor shaft of each of the fourth motors 19d. When the workpiece is fixed on the active slide 18a and the driven slide 18b, the active slide 18a and the driven slide 18b move synchronously.

[0047] Therefore, the motor shaft of the fourth motor 19d drives the fourth drive gear 19e to rotate in both directions, thereby controlling the translation of the positioning fixture 18 with high precision. Furthermore, the fourth motor 19d is preferably a servo motor, which can further improve the precision control of the translation of the positioning fixture 18.

[0048] In this embodiment, both the active slide 18a and the driven slide 18b are equipped with a waste removal mechanism 24 for removing waste material located on the upper surface of the receiving plate 19a1 to one side of the width direction of the slide rail 17a, thereby improving the cleaning effect on the upper surface of the receiving plate 19a1.

[0049] Please see Figure 3 and Figure 4 The upper surface of the receiving plate 19a1 is recessed to form two receiving grooves 19a11 located below the corresponding waste removal mechanism 24, thereby reliably collecting waste generated from laser cutting. Meanwhile, each waste removal mechanism 24 includes a connecting assembly 24a mounted on the corresponding active slide 18a or driven slide 18b, and a removal assembly 24b for removing waste from the corresponding receiving groove 19a11 and transferring it to one side of the slide rail 17a in the width direction. Each set of removal assemblies 24b independently removes waste from the receiving groove 19a11, ensuring high reliability.

[0050] Specifically, the bottom of the receiving groove 19a11 is recessed to form multiple parallel guide slots 19a12 that run through the receiving plate 19a1 along the width direction of the slide rail 17a. Each rejection assembly 24b includes a push-pull shaft 24b1 extending along the length direction of the slide rail 17a, rejection push blocks 24b2 that are slidably installed in the guide slots 19a12, and push-pull mechanisms that are hinged to the same end of each rejection push block 24b2. The crank 24b3, the end of each push-pull crank 24b3 away from the material rejection push block 24b2 is respectively hinged to the corresponding push-pull shaft 24b1. The connecting assembly 24a includes a push-pull plate 24a1 fixedly connected to the corresponding active slide 18a or driven slide 18b and a push-pull connecting rod 24a2 hinged to the corresponding push-pull plate 24a1. The end of each push-pull connecting rod 24a2 away from the push-pull plate 24a1 is respectively hinged to the corresponding push-pull shaft 24b1.

[0051] Therefore, when the active slide 18a and the driven slide 18b move synchronously, each push-pull plate 24a1 can push and pull the corresponding push-pull shaft 24b1 through the corresponding push-pull connecting rod 24a2. The push-pull shaft 24b1 then pushes and pulls the scrap pusher block 24b2 synchronously through each push-pull crank 24b3, thereby pushing the waste in each guide slot 19a12 to the outside of the slide module. Since the cutting waste is usually a metal sheet (whether round or strip-shaped) produced by opening, designing the width of the guide slot 19a12 to be smaller than the metal sheet ensures that the metal sheet is placed obliquely in the guide slot 19a12 and is easily pushed by the scrap pusher block 24b2. If the metal sheet is round, the scrap pusher block 24b2 pushes the round metal sheet slightly, and the round metal sheet can roll into the waste collection box 25 under the support of the side wall of the guide slot 19a12 and by its own inertia.

[0052] Furthermore, to facilitate the ejection of metal sheets from the guide slots 19a12, in this embodiment, within the same receiving groove 19a11, each guide slot 19a12 is synchronously and downwardly inclined from one end of each rejecting pusher 24b2 near the push-pull shaft 24b1 towards the other end, i.e., inclined downwards towards the waste collection box 25. Since each guide slot 19a12 is designed to be inclined downwards towards the output end, whether it is a circular or strip-shaped metal sheet, the rejecting pusher 24b2 only needs to apply a small pushing force as set, allowing the circular and strip-shaped metal sheets to smoothly slide out along the guide slots 19a12 under their own gravity and inertia. This not only improves cleaning ability and efficiency but also better avoids jamming problems.

[0053] Furthermore, in order to make the metal sheet more easily pushed by the ejector block 24b2 in the guide slot 19a12, in this embodiment, the two side walls of the guide slot 19a12 are mirrored, and the guide slot 19a12 is composed of inclined section 19a121 and vertical section 19a122 distributed from bottom to top. Specifically, within the same guide seam 19a12: the heights of the inclined sections 19a121 at all positions are equal, and the heights of the vertical sections 19a122 at all positions are also equal; both inclined sections 19a121 are sloping structures, and the distance between the two inclined sections 19a121 gradually increases towards the bottom of the groove, meaning that the cross-section of the guide seam 19a12 at the two inclined sections 19a121 positions is trapezoidal; both vertical sections 19a122 are vertical planar structures, meaning that the cross-section of the guide seam 19a12 at the two vertical sections 19a122 positions is rectangular, thus enabling the metal sheet produced by laser cutting to be supported at the inclined sections 19a121 positions and to have a certain angle with the vertical sections 19a122, making it easier for it to be pushed by the material pusher block 24b2.

[0054] Accordingly, please see Figure 5 Each of the ejector blocks 24b2 includes a connecting arm 24b21 hinged to the corresponding push-pull crank 24b3 and an ejector block 24b22 integrally formed at the end of the corresponding connecting arm 24b21 away from the push-pull crank 24b3. The lower part of each ejector block 24b22 integrally forms a reduced-diameter section 24b221 adapted to the two corresponding vertical sections 19a122 and a trapezoidal section 24b222 adapted to the two corresponding inclined sections 19a121. Therefore, the metal sheet produced by laser cutting is both tilted and supported in the guide slot 19a12, and does not completely adhere to the bottom or sidewall of the guide slot 19a12, allowing the ejector block 24b2 to easily push the metal sheet in the guide slot 19a12, avoiding jamming problems.

[0055] Furthermore, in this embodiment, the upper part of the rejection block 24b22 is designed to be wider, so that the gap between the upper parts of adjacent rejection blocks 24b22 is very small (usually much smaller than the diameter or width of the metal sheet), thereby pushing away the waste that has not fallen into the guide gap 19a12, ensuring the thoroughness of waste rejection.

[0056] In this embodiment, in order to ensure the stability of the operation of the push-pull shaft 24b1, push-pull shaft guide grooves 19a13 adapted to the corresponding push-pull shaft 24b1 are provided on both sides of the receiving groove 19a11. The two ends of each push-pull shaft 24b1 are slidably embedded in the corresponding push-pull shaft guide groove 19a13, thereby ensuring the synchronicity of the operation of each material rejection push block 24b2 and avoiding jamming problems.

[0057] Please see Figure 3 and Figure 4 The active slide 18a includes an active slide base 18a1 fixedly mounted on the slider corresponding to the fourth linear guide rail 19c, and an active slide fixed mounting plate 18a2, an active slide movable mounting plate 18a3, and an active slide connecting seat 18a4 all mounted on the active slide base 18a1. The active slide connecting seat 18a4 is fixedly mounted on one end of the active slide base 18a1 and connected to the corresponding waste removal mechanism 24. The active slide fixed mounting plate 18a2 is fixedly mounted on the other end of the active slide base 18a1. The active slide base 18a1 has a first strip hole 18a11 extending along the width direction of the bed 12 in the middle. The active slide movable mounting plate 18a3 is slidably mounted in the first strip hole 18a11 by at least two bolts that can be locked or unlocked. The fourth motor 19d is mounted next to the active slide connecting seat 18a4.

[0058] Similarly, the driven carriage 18b includes a driven carriage base 18b1 fixedly mounted on the slider corresponding to the fourth linear guide rail 19c, and a driven carriage fixed mounting plate 18b2, a driven carriage movable mounting plate 18b3, and a driven carriage connecting seat 18b4, all mounted on the driven carriage base 18b1. The driven carriage connecting seat 18b4 is fixedly mounted on one end of the driven carriage base 18b1 and connected to the corresponding scrap removal mechanism 24. The driven carriage fixed mounting plate 18b2 is fixedly mounted on the other end of the driven carriage base 18b1. The driven carriage base 18b1 has a second strip hole 18b11 extending along the width direction of the bed 12 in the middle. The driven carriage movable mounting plate 18b3 is slidably mounted in the second strip hole 18b11 by at least two bolts that can be locked or unlocked.

[0059] Therefore, by adjusting the position of the active carriage movable mounting plate 18a3 on the active carriage base 18a1 and the position of the driven carriage movable mounting plate 18b3 on the driven carriage base 18b1, it can adapt to workpieces of different sizes and has good versatility.

[0060] Furthermore, in the active carriage mounting plate 18a2 and the driven carriage mounting plate 18b2, one of them has a bolt hole array consisting of an array of bolt holes, and the other has a strip hole array consisting of an array of strip holes, which further improves the applicability to workpieces of different sizes.

[0061] In this embodiment, the slide drive assembly includes a fifth rack 21 and two fifth linear guides 20 mounted parallel to each other on the slide track 17a, and a fifth motor 22 mounted on the slide 17b respectively. The two slides 17b are respectively fixedly mounted on the corresponding sliders of the two fifth linear guides 20. The motor shafts of the fifth motors 22 are synchronously rotated and fitted with fifth drive gears 23 that mesh with the fifth rack 21.

[0062] Therefore, the motor shaft of the fifth motor 22 drives the fifth drive gear 23 to rotate in both directions, thereby enabling the slide table 17b to move with high control precision. Furthermore, the fifth motor 22 is preferably a servo motor, which can further improve the precision control of the translation of the slide table 17b.

[0063] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
