Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically to a two-degree-of-freedom self-cleaning slide module suitable for a three-dimensional laser cutting system. Background Technology

[0002] 3D laser cutting machines are high-end equipment that integrates optics, mechanics, electronics, and pneumatics. They are considered the crown jewel of laser processing equipment and are mainly used for cutting holes and trimming edges on complex stamped parts. They are widely used in aerospace, new energy vehicles and other fields.

[0003] 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.

[0004] Furthermore, the waste generated by existing 3D laser cutting machines (3D laser cutting machines are mainly used for hole making and edge cutting, so the waste generated from hole making is usually a round metal sheet, and the waste generated from edge cutting is usually a strip metal sheet) generally requires the machine to be stopped for manual cleaning of the slide table, or special tools to be used to clean the slide table, which will affect the production cycle and processing efficiency.

[0005] Solving these problems is now a top priority. Utility Model Content

[0006] In view of this, the present invention provides a two-degree-of-freedom self-cleaning slide module suitable for three-dimensional laser cutting systems.

[0007] The technical solution is as follows:

[0008] The first aspect of this application relates to a two-degree-of-freedom self-cleaning slide module suitable for a three-dimensional laser cutting system, including a track slide conveying mechanism. The track slide conveying mechanism includes a slide track and at least one slide that can move along the length direction of the slide track under the drive of a slide drive assembly. Each slide is equipped with a positioning fixture that can move along the width direction of the slide track under the drive of a fixture translation assembly. Each fixture translation assembly includes a fixture base fixedly installed on the corresponding slide and a fixture translation module for driving the corresponding positioning fixture to move along the width direction 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 one side of the width direction of the slide track is synchronously connected to the positioning fixture.

[0009] The above-mentioned two-degree-of-freedom self-cleaning slide module, suitable for 3D laser cutting systems, provides two online adjustable degrees of freedom in the horizontal direction. Combined with the multiple degrees of freedom implemented on the crossbeam module, it enables redundant processing modes with multiple degrees of freedom. This allows for more efficient and flexible laser cutting, enabling the cutting of more complex surfaces and achieving higher processing accuracy. Furthermore, when the positioning fixture moves along the width of the slide track, it can drive each waste removal mechanism to move synchronously, pushing the waste on the fixture base to the outside of the slide module. Especially for circular metal sheets, only a slight push is needed to allow them to roll out of the slide using their own inertia. This not only has high efficiency and minimal impact on production cycle, but also, since the waste removal mechanism is mounted on and controlled by the positioning fixture, the mechanical structure has a high degree of integration.

[0010] In some embodiments, the tooling base includes a receiving plate and two guide rail mounting brackets fixedly mounted on corresponding slides. The two guide rail mounting brackets are mounted opposite each other on both sides of the receiving plate along the length of the slide 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 track. The positioning tooling includes an active slide and a driven slide disposed on both sides of the receiving plate. The active slide and the driven slide are respectively fixedly mounted on the sliders of the corresponding fourth linear guide rails. A fourth motor is mounted on the active slide. A fourth drive gear that meshes with the fourth rack is synchronously mounted on the motor shaft of the fourth motor. A waste removal mechanism for removing waste material located on the upper surface of the receiving plate to one side of the slide track width direction is mounted on both the active slide and the driven slide.

[0011] In some embodiments, the upper surface of the receiving plate is recessed to form two receiving grooves located below the corresponding waste removal mechanism. 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 to one side of the slide track width direction.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] Each of the ejector blocks includes a connecting arm that is hinged to the corresponding push-pull crank and an ejector block integrally formed at the end of the corresponding connecting arm away from the push-pull crank. The lower part of each ejector block is integrally formed with a reduced diameter section that matches the two corresponding vertical sections and a trapezoidal block section that matches the two corresponding inclined sections.

[0016] 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.

[0017] In some embodiments, each side wall of the receiving groove is provided with a push-pull shaft guide groove adapted to the corresponding push-pull shaft, and the two ends of each push-pull shaft are slidably embedded in the corresponding push-pull shaft guide groove.

[0018] In some embodiments, the active carriage includes an active carriage base fixedly mounted on a slider corresponding to the fourth linear guide, and an active carriage fixed mounting plate, an active carriage movable mounting plate, and an active carriage connecting seat all mounted on the active carriage base. The active carriage connecting seat is fixedly mounted on one end of the active carriage base and connected to the corresponding scrap removal mechanism. The active carriage fixed mounting plate is fixedly mounted on the other end of the active carriage base. The active carriage base has a first strip-shaped hole extending along the width direction of the bed in the middle. The active carriage movable mounting plate is slidably mounted in the first strip-shaped hole by at least two bolts that can be locked or unlocked. The fourth motor is mounted next to the active carriage connecting seat.

[0019] The driven carriage includes a driven carriage base fixedly installed on the slider corresponding to the fourth linear guide rail, and a driven carriage fixed mounting plate, a driven carriage movable mounting plate, and a driven carriage connecting seat, all installed on the driven carriage base. The driven carriage connecting seat is fixedly installed at one end of the driven carriage base and connected to the corresponding waste removal mechanism. The driven carriage fixed mounting plate is fixedly installed at the other end of the driven carriage base. The driven carriage base has a second strip hole extending along the width direction of the bed in the middle. The driven carriage movable mounting plate is slidably installed in the second strip hole by at least two bolts that can be locked or unlocked.

[0020] Of the active carriage mounting plate and the driven carriage mounting plate, one 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.

[0021] In some embodiments, the slide drive assembly includes a fifth rack and two fifth linear guides mounted parallel to each other on the slide track, and a fifth motor mounted on each slide. The two slides are respectively fixedly mounted on the corresponding sliders of the two fifth linear guides. The motor shafts of the fifth motors are synchronously fitted with fifth drive gears that mesh with the fifth rack.

[0028] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown, a two-degree-of-freedom self-cleaning slide module suitable for a three-dimensional laser cutting system mainly includes a track slide conveying mechanism 17. The track slide conveying mechanism 17 includes a slide track 17a and at least one slide 17b that can move along the length of the slide track 17a under the drive of a slide drive assembly. Typically, the slide track 17a extends in a straight line in the horizontal direction, and one or two slides 17b are provided on the slide track 17a. In particular, when two slides 17b are provided on the slide track 17a, the two slides 17b can independently load and unload materials from both ends of the slide track 17a under the drive of their respective slide drive assemblies, or they can work together as a whole to load and unload materials from one end of the slide track 17a.

[0030] Specifically, when processing large workpieces, the two slides 17b work together as a whole to load and unload from one end of the slide rail 17a; when processing two sets of small workpieces independently (the two sets of small workpieces can be the same workpiece or different workpieces), the two slides 17b work independently to load and unload from both ends of the slide rail 17a.

[0031] Please see Figures 1-5 Each slide 17b is equipped with a positioning fixture 18 that can move along the width direction of the slide track 17a under the drive of the fixture translation component 19.

[0032] Each tooling translation component 19 includes a tooling base 19a fixedly installed on the corresponding slide table 17b and a tooling translation module for driving the corresponding 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 material located on the upper surface of the tooling base 19a to one side of the width direction of the slide table track 17a is synchronously connected to the positioning tooling 18.

[0033] 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 the positioning fixture 18 moves along the width direction of the slide track 17a, it can drive each waste removal mechanism 24 to move synchronously with it, thereby pushing the waste located on the fixture base 19a to the outside of the slide module. Especially for circular metal sheets, only a slight push is needed to roll them out of the slide using their own inertia. This is not only highly efficient but also has little impact on the production cycle. For strip metal sheets, the working stroke of the waste removal mechanism 24 needs to cover the fixture base 19a as much as possible. Moreover, the waste removal mechanism 24 is mounted on and controlled by the positioning fixture 18, resulting in a high degree of integration of the mechanical structure.

[0034] 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 corresponding slide table 17b and fixedly connected to the receiving plate 19a1, ensuring the stability and reliability of the tooling base 19a.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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 push 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 push block 24b2. If the metal sheet is round, the scrap push block 24b2 pushes the round metal sheet slightly, and the round metal sheet can roll outside the guide slot 19a12 by its own inertia under the support of the side wall of the guide slot 19a12.

[0041] Furthermore, to facilitate the ejection of the metal sheet from the guide slot 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. Since each guide slot 19a12 is designed to slope 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 slot 19a12 under their own gravity and inertia. This not only improves cleaning ability and efficiency but also better avoids jamming problems.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] Please see Figure 1 and Figure 2 On the same side of the slide rail 17a in the width direction, there is a waste collection box 25 corresponding to each slide 17b. Each waste removal mechanism 24 can remove the waste on the corresponding tooling base 19a into the corresponding waste collection box 25, thereby facilitating the recycling of waste.

[0053] 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.
