[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0050] The following is for reference. Figures 1-13 The following describes the lifting module 100 and the laser processing equipment according to embodiments of the present invention.

[0051] The lifting module 100 of this utility model embodiment includes a dust cover 1 and a lifting component 2.

[0052] The dust cover 1 has a receiving groove 111, and the lifting member 2 is at least partially received in the receiving groove 111. The lifting member 2 includes a driving member 21 and a lifting seat 22. At least a portion of the lifting seat 22 extends out of the receiving groove 111 to form a lifting platform. The lifting platform has a lifting surface. The driving member 21 is connected to the lifting seat 22 to drive the lifting seat 22 to move the lifting platform along the height direction of the dust cover 1 (e.g., ...). Figure 5 (As shown in the up and down direction) moves back and forth.

[0053] The lifting module 100 of this utility model embodiment can protect the driving component 21 of the lifting component 2 by setting the dust cover 1, providing the driving component 21 with a relatively independent space and an additional barrier, which can greatly reduce the diffusion of dust generated during the engraving process into the driving component 21, thereby extending its service life and maintaining high-precision operation.

[0054] Therefore, the lifting module 100 of this utility model embodiment has the advantages of long service life and good repeatability.

[0055] For example, Figure 5 As shown, at least a portion of the lifting seat 22 extends out of the receiving groove 111 from the front to form a lifting platform. The driving member 21 can drive the lifting seat 22 to move in the vertical direction and relies on the dust cover 1 pair.

[0056] like Figure 5 , Figure 7 , Figure 9 and Figure 10As shown, the dust cover 1 includes a cover 11 and a flexible sealing member 12. The cover 11 is provided with a receiving groove 111. A side slot 112 communicating with the receiving groove 111 is formed on one side of the cover 11. The flexible sealing member 12 can be opened and closed to seal the side slot 112. At least a part of the lifting seat 22 and at least a part of the driving member 21 are disposed in the receiving groove 111. The lifting seat 22 extends at least partially out of the side slot 112 to form a lifting platform.

[0057] The lifting module 100 of this utility model divides the dust cover 1 into a cover 11 and a flexible sealing component 12. The separate cover 11 and flexible sealing component 12 allow for quick disassembly of screws to replace the core function when the parts are damaged, without the need to disassemble the entire machine.

[0058] Furthermore, the lifting module 100 of this embodiment can avoid setting a side slot 112 on the side facing the lifting surface by means of the flexible sealing member 12 (in order to cooperate with the reciprocating movement of the lifting seat 22 along the height direction of the dust cover 1, it can be...). Figure 5 The side slot 112 shown in the diagram causes a large amount of dust to enter the housing, affecting the precision and service life of the drive component 21. Because the front side faces the laser processing surface, dust is relatively concentrated in this area, and a large amount of dust will spill into the housing 11. Therefore, the flexible sealing component 12 can achieve a proper seal of the side slot 112 of the dust cover 1 without affecting the movement of the lifting platform, further increasing the dustproof effect of the dust cover 1.

[0059] like Figure 5 , Figure 7 , Figure 9 and Figure 10 As shown, the lifting seat 22 is provided with a clearance channel 5, and the flexible sealing member 12 passes through the clearance channel 5. The flexible sealing member 12 is connected to the cover 11 at both ends in the height direction of the dust cover 1, and the flexible sealing member 12 contacts the side slots 112 of the cover 11 on both sides in the width direction of the dust cover 1.

[0060] The lifting module 100 of this utility model embodiment has a flexible sealing member 12 inserted into the avoidance channel 5. The flexible sealing member 12 contacts the side slots 112 of the cover 11 on both sides of the width direction of the dust cover 1. During the lifting process of the lifting seat 22, the flexible sealing member 12 can be kept in contact with the side of the dust cover 1. That is, the flexible sealing member 12 can achieve a sealing fit with the side slots 112 of the dust cover 1 without affecting the movement of the lifting platform, which further increases the dustproof effect of the dust cover 1.

[0061] like Figure 7 As shown, the flexible sealing element 12 is attracted to the cover 11 to seal the side slot 112.

[0062] The lifting module 100 of this utility model embodiment is attracted to the cover 11 by the flexible sealing member 12. During the movement of the lifting platform, except for the part of the flexible sealing member 12 that extends out of the receiving groove 111 of the lifting seat 22, the other parts of the flexible sealing member 12 are attracted and sealed with the receiving groove 111, which further increases the dustproof effect of the dust cover 1.

[0063] like Figure 9 As shown, the cover 11 includes at least a metal shell, and the flexible sealing member 12 includes a flexible metal strip 121 and magnetic sealing strips 122 disposed on both sides of the flexible metal strip 121 in the width direction of the dust cover 1. The flexible metal strip 121 is magnetically attached to the cover 11 through the magnetic sealing strips 122.

[0064] The lifting module 100 of this embodiment of the invention magnetically attaches the flexible metal strip 121 to the cover 11 via the magnetic seal 122. This allows the flexible metal strip 121 and the cover 11 to be attached without interfering with the movement of the lifting seat 22, while also adapting to the position of the base 221. Therefore, the lifting module 100 of this embodiment of the invention further enhances its sealing performance.

[0065] For example, both the metal shell and the flexible metal strip 121 have magnetic properties. Alternatively, one of the metal shell 11 and the flexible metal strip 121 can be made of ferrous or iron-containing metal, and the other of the metal shell 11 and the flexible metal strip 121 can be a magnetic component.

[0066] The lifting module 100 of this utility model embodiment is not limited thereto. The flexible sealing component 12 can also be attached to the cover 11 by electrostatic attraction or suction cup.

[0067] The flexible sealing element 12 consists of a flexible metal strip 121 and magnetic sealing strips 122 disposed on both ends of the flexible metal strip 121 in a second direction. The flexible metal strip 121 is magnetically attached to the cover 11 through the magnetic sealing strips 122. While not interfering with the movement of the lifting seat 22, the flexible metal strip 121 and the cover 11 can be made to fit together according to the position of the base body 221. Therefore, the lifting module 100 of this embodiment of the invention further enhances its sealing performance.

[0068] Furthermore, the housing 11 includes a U-shaped plate 101 and a top plate 102, with the top plate 102 sealingly disposed on the top surface of the U-shaped plate 101. Additionally, the housing of the motor 211 can be sealed against the lower end surface of the U-shaped plate 101, further enhancing the airtightness of the housing 11.

[0069] like Figure 9 and Figure 10As shown, the lifting seat 22 includes a base body 221 and a support seat. The base body 221 is driven and connected to the drive member 21. A portion of the base body 221 extends into a receiving groove 111 in the direction close to the side slot 112. The support seat is located outside the receiving groove 111. The support seat has a lifting platform and is connected to a portion of the base body 221. The support seat and the base body 221 are spaced apart to form a clearance passage 5.

[0070] The lifting module 100 of this utility model divides the lifting seat 22 into a base body 221 and a support seat, and sets an avoidance channel 5 between the support seat and the base body 221. The separate structure of the base body 221 and the support seat is relatively simple and easy to process and assemble.

[0071] like Figures 11 to 13 As shown, the base body 221 includes a mating plate 2211 and a clamping plate 2212 extending from the edge of the mating plate 2211 bent toward the side slot 112. The mating plate 2211 is driven to engage with the driving member 21. The lifting seat is connected to the clamping plate 2212, and a clearance channel 5 is formed between the lifting seat and the clamping plate 2212. It can be understood that the mating plate 2211 and the clamping plate 2212 are integrally bent into shape.

[0072] The lifting module 100 of this embodiment of the present invention has a relatively separate structure (e.g., a welded structure of the plate and the mating plate 2211) by dividing the base body 221 into a mating plate 2211 and a clamping plate 2212 that extends from the edge of the mating plate 2211 towards the side slot 112. The lifting module 100 of this embodiment of the present invention has the advantage of good structural integrity.

[0073] Optionally, the clamping plate 2212 is provided with limiting grooves on both sides of the dust cover 1 in the width direction, and the flexible metal strip 121 is disposed in the limiting grooves to limit the flexible metal strip 121.

[0074] like Figures 11 to 13 As shown, the lifting seat includes a pressure roller 222 and a tray seat 223. The tray seat 223 is connected to the clamping plate 2212. A lifting platform is formed on the tray seat 223. The tray seat 223 and the base body 221 are spaced apart in a first direction to form a clearance channel 5. The pressure roller 222 is disposed at both ends of the clearance channel 5 in the height direction of the dust cover 1, and the pressure roller 222 is rotatably connected to the tray seat 223. The flexible sealing member 12 is clamped between the pressure roller 222 and the tray seat 223.

[0075] The lifting module 100 of this utility model divides the lifting seat into a pressure roller 222 and a tray seat 223. The pressure roller 222 is disposed at both ends of the clearance channel 5 in the height direction of the dust cover 1. The pressure roller 222 is rotatably connected to the tray seat 223. The pressure roller 222 can not only make the flexible sealing member 12 fit tightly against the side groove 112 of the cover 11 through the pressure roller 222 (pressing the flexible sealing member 12 to fit the cover 11 when the lifting seat 22 is raised to different positions), thus improving the sealing performance of the cover 11, but also play a good guiding role for the flexible sealing member 12 during the movement of the lifting seat 22.

[0076] Optionally, two pressure rollers 222 may be provided, with the two pressure rollers 222 respectively arranged at both ends of the clearance channel 5 along the height direction of the dust cover 1. And the central axis of each pressure roller 222 may extend along a second direction.

[0077] Optionally, the pressure roller 222 is a silicone pressure roller. Silicone pressure rollers have the advantage of good wear resistance.

[0078] like Figures 11 to 13 As shown, the pallet seat 223 includes a pallet plate portion 2231, a pallet portion 2232, and at least two mounting portions 2233. The pallet portion 2232 and the mounting portions 2233 are disposed opposite each other on two sides in a first direction. A lifting platform is formed on the pallet portion 2232. A pressure roller 222 extends along the width direction of the side groove 112, and both ends of the pressure roller 222 are rotatably connected to the mounting portions 2233. The pressure roller 222 is connected to the pallet plate portion 2231, and the pallet plate portion 2231 is connected to the plurality of mounting portions 2233 (e.g., ...). Figure 8 The four mounting parts 2233 shown limit the groove 2234. A part of the clamping plate 2212 is disposed in the groove 2234. A lifting surface is formed on the tray part 2232. The flexible sealing member 12 is clamped between the pressure roller 222 and the tray part 2231.

[0079] The lifting module 100 of this embodiment is divided into a pallet portion 2231, a pallet portion 2232, and at least two mounting portions 2233 by a pallet seat 223. The pallet portion 2231 and the multiple mounting portions 2233 limit the groove 2234, and a part of the clamping plate 2212 is disposed in the groove 2234, which can save space in the lifting seat 22. At the same time, the clamping plate 2212 and the pallet portion 2231 are arranged face to face, which helps to increase the contact surface between the flexible sealing member 12 and the clamping plate 2212, thus helping to reduce wear on the flexible sealing member 12.

[0080] like Figure 9As shown, the housing 11 has one of a limiting groove 113 and a limiting protrusion 2213, and the base 221 has the other of a limiting groove 113 and a limiting protrusion 2213. The limiting protrusion 2213 is engaged within the limiting groove 113. It can be understood that the housing 11 has a limiting protrusion 2213, and the base 221 has a limiting groove 113. Alternatively, the housing 11 has a limiting groove 113, and the base 221 has the other of a limiting protrusion 2213.

[0081] The lifting module 100 of this embodiment of the invention is fixed to the cover 11 and the base 221 by means of a limiting slot 113 and a limiting protrusion 2213, which enables the positioning and installation of the cover 11. Therefore, the lifting module 100 of this embodiment of the invention improves the ease of installation.

[0082] like Figure 9 As shown, a limiting groove 113 is provided on the lower end face of the cover 11. The base body 221 includes a seat body and a limiting protrusion 2213. The seat body is sealed on one end of the cover 11, and the limiting protrusion 2213 is provided on the side of the seat body facing the limiting groove 113.

[0083] The lifting module 100 of this utility model has the advantages of high processing convenience and good disassembly convenience by providing a limiting groove 113 on the lower end face of the cover 11 and the cooperation of the limiting groove 113 and the limiting protrusion 2213 for limiting.

[0084] like Figures 7 to 10 As shown, the drive component 21 includes a motor 211 and a lead screw 212. The lead screw 212 is connected to the output end of the motor 211, and the lifting seat 22 is threadedly engaged with the lead screw 212. The lead screw drive structure formed by the lead screw 212 and the lifting seat 22 has the advantage of high movement accuracy.

[0085] like Figures 7 to 9 As shown, the lifting module 100 of this utility model embodiment also includes a guide rod 3 extending in the dust cover 1 along the height direction of the dust cover 1. The two ends of the guide rod 3 are respectively connected to the end of the drive member 21 and the dust cover 1. The lifting seat 22 has a guide hole 2214, and the guide rod 3 passes through the guide hole 2214.

[0086] The lifting module 100 of this utility model uses a guide rod 3 to guide the movement of the lifting seat 22, so as to avoid the lifting seat 22 from tilting during the movement, thereby increasing the stability of the lifting seat 22.

[0087] Furthermore, the guide rod 3 can be a guide shaft with a smooth surface.

[0088] The dust cover 1 is detachably connected to the drive unit 21. When a component is damaged, the screws can be quickly removed to replace the core function without disassembling the entire machine. This helps reduce the difficulty of maintenance and disassembly. Optionally, the dust cover 1 and the drive unit 21 can be limited by screws 4. During lifting, the main force point is on the limit slot 113, avoiding force on the screws in the front and rear directions. When a component is damaged, the screws can be quickly removed to replace the core function without disassembling the entire machine.

[0089] Furthermore, the dust cover 1 and the drive unit 21 can be installed by screws 4.

[0090] The laser processing equipment of this embodiment includes a track device and a laser device 600 movably mounted on the track device, a support platform 200, and a plurality of lifting modules 100 according to any one of the above. The lifting surface of each lifting module 100 is connected to the support platform 200, which is used to support the workpiece to be processed. The laser device is used to output laser light to perform laser processing on the workpiece. Therefore, the laser processing equipment of this embodiment has the advantages of long service life and good repeatability.

[0091] like Figures 1 to 4 As shown, the laser processing equipment of this embodiment further includes a frame 400 and a cover door 500. The cover door 500 is rotatably connected to the frame 400. The frame 400 and the cover door 500 enclose a processing space. The cover door 500 can be rotated to open or close the processing space. The lifting module 100 is disposed inside the frame 400. In this embodiment, the frame 400 serves as a base support and can adopt a frame structure, chassis structure, or other structure. The frame 400 can be a cuboid or a cube, and the support platform 200 is disposed on the lifting surface of the lifting module 100. The laser device 600 is disposed within the processing space and can output laser light to perform laser processing on the workpiece. Optionally, the cover door 500 is at least partially provided with a semi-transparent window. The window allows the user to observe the laser device 600 processing the workpiece inside the frame 400, and the window can filter the high-power laser light output and reflected by the laser device 600, thus isolating and protecting the user without affecting the observation of the processing progress.

[0092] In some embodiments, a track device is disposed within the frame 400. The track device includes an X-axis track 301 and a Y-axis track 302. The X-axis track 301 is movably disposed on the Y-axis track 302. The laser device 600 is movably disposed on the X-axis track 301, thereby enabling the laser device 600 to move within the processing space via the track device. The workpiece to be processed is placed at the bottom of the processing space. During the processing, the laser device 600 moves above the workpiece and outputs laser light, thereby enabling laser processing of the workpiece.
