Description

Technical Field

[0001] The utility model relates to the technical field of laser engraving devices, in particular to a workpiece heat dissipation module of a laser engraving machine. Background Art

[0002] A laser engraving machine is an advanced device that uses a laser beam to cut, engrave or mark the surface of a material. The laser engraving machine focuses a high-energy laser beam onto a very small spot. This spot generates high temperature on the surface of the material, causing the material to melt, vaporize or produce a chemical reaction instantly, thereby achieving the purpose of cutting, engraving or marking. During the laser engraving process, the high temperature of the laser can cause the workpiece to overheat, and some workpieces are prone to deformation and other problems at high temperatures. Therefore, heat dissipation of the workpiece is crucial.

[0003] The utility model patent with authorization announcement number CN116551202A discloses a laser engraving device for advertising production, which includes a laser engraving device body, which includes a laser head, an engraving table, a clamp and a heat dissipation mechanism. A base plate is provided at the bottom of the engraving table, a bracket is installed at the edge of the base plate, a longitudinal shift module is installed on the top of the bracket, a transverse shift module is installed on the inner side of the longitudinal shift module, and a laser head is installed on the bottom of the transverse shift module. The engraving table is installed directly below the laser head, the inner side of the engraving table is hollow, and a top plate is installed on the inner side of the engraving table, a clamp is installed on the surface of the top plate, and an independent workpiece plate to be engraved is installed on the inner side of each clamp, a heat dissipation mechanism is installed on the side of the engraving table, and the bottom of the heat dissipation mechanism is placed on the surface of the base plate. The advertising production laser engraving device is equipped with a hollow support plate at the bottom of each clamp. After the metal workpiece to be engraved is placed on the support plate, the bottom of the workpiece can be fitted with the thermal pad on the surface of the support plate. Then, during the subsequent laser engraving process, the heat generated when the metal workpiece is engraved can be promptly discharged outward with the help of the external heat dissipation mechanism, thereby improving the heat dissipation performance and reducing the risk of burns when it is subsequently removed.

[0004] Although the advertising laser engraving device can dissipate heat for the workpiece, the device has a poor heat dissipation effect on the workpiece. Specifically, in the device, the workpiece is placed on a pallet, which conducts the heat of the workpiece and then dissipates it. This indirect heat dissipation method has the problems of poor heat dissipation effect and low heat dissipation efficiency. It is difficult to effectively dissipate the heat of the workpiece and it is difficult to meet the heat dissipation needs of the workpiece. In view of this, we propose a workpiece heat dissipation module for a laser engraving machine. Utility Model Content

This design is conducive to direct heat dissipation of the workpiece through the set fan, ensures the heat dissipation effect of the workpiece, improves the heat dissipation efficiency of the workpiece, and avoids the deformation of the workpiece due to the high temperature generated during the laser engraving process.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] This embodiment provides a technical solution:

[0029] See also Figure 1-Figure 5 As shown, the workpiece heat dissipation module of the laser engraving machine includes a machine base 1, a gantry 2 is installed above the machine base 1, and a laser head 20 is installed on the gantry 2: a heat dissipation component 3 is provided on the top of the machine base 1; the heat dissipation component 3 includes a support plate 30, and a detachable top plate 31 for carrying the workpiece is provided on the top of the support plate 30; a sliding cavity 301 is provided on the top of the support plate 30, and two slide plates 32 are slidably installed in the sliding cavity 301, and a notch 320 is provided on the slide plates 32, and a rack 33 is fixed at the notch 320, and a gear 34 is meshed between the two racks 33. A gear for driving the gear is installed at the bottom of the support plate 30. The motor 35 rotates the wheel 34; the two opposite ends of the two slides 32 are fixed with a base 36, the top of the base 36 is fixed with a limit block 360, and the top center of the limit block 360 is provided with a fixing hole 361; a fixing plate 37 is installed above the base 36, and two air holes 370 are provided on the fixing plate 37, and fans 38 are installed on the outer wall of the fixing plate 37 at the air holes 370; the bottom of the fixing plate 37 is provided with a limit groove 371 that is plugged into the limit block 360; the top of the fixing plate 37 is threadedly connected to a connecting bolt 39, and the bottom end of the connecting bolt 39 is inserted into the fixing hole 361.

[0030] In this embodiment, the slide plates 32 are each provided with a positioning slot 322. Two positioning blocks 303 are fixed to the bottom of the slide cavity 301, and the positioning blocks 303 are slidably connected to the positioning slots 322. The positioning blocks 303 and the positioning slots 322 limit the horizontal position of the slide plates 32, preventing the slide plates 32 from falling out of the slide cavity 301.

[0031] In this embodiment, guide rails 302 are fixed to both side walls of the sliding cavity 301, and guide grooves 321 are formed on the outer walls of the slide plate 32 for sliding connection with the guide rails 302. The arrangement of the guide rails 302 and the guide grooves 321 facilitates smooth horizontal movement of the slide plate 32 and ensures its stability.

[0032] In this embodiment, the cross-sections of the stopper 360 and the stopper groove 371 are both trapezoidal, and the stopper 360 and the base 36 are integrally formed. The trapezoidal shape facilitates a stable connection between the base 36 and the fixing plate 37, while the integrally formed structure ensures the connection strength between the stopper 360 and the base 36, ensuring that the stopper 360 and the base 36 support and secure the fixing plate 37.

[0033] In this embodiment, the cross-section of the support plate 30 is U-shaped, and the support plate 30 is fixedly connected to the top plate 31 by bolts. The bolt fixing method ensures the reliability of the connection between the support plate 30 and the top plate 31, and has the advantage of easy disassembly and assembly.

[0034] In this embodiment, the cross-section of the slide plate 32 is L-shaped, and the slide plate 32 is fixedly connected to the base 36 by bolts. The bolt fixing method ensures the reliability of the connection between the slide plate 32 and the base 36, which is conducive to the stable adjustment of the position of the fixing plate 37.

[0035] In this embodiment, the cross-section of the air hole 370 is circular, and the diameter of the air hole 370 is 24-26 cm. The preferred diameter of the air hole 370 is 25 cm. This design facilitates the wind to be blown directly through the air hole 370 to the workpiece for heat dissipation.

[0036] It should be added that the laser engraving machine is composed of structures such as a laser, a transmission system, a control system and a mechanical platform, and the machine base 1, the gantry 2 and the laser head 20 in this embodiment are all common structures of laser engraving machines in the prior art. The principles are well known to people in this field and will not be repeated here.

[0037] During specific use, the user first turns on the power of the motor 35, and the motor 35 starts to work. The rotation of the motor 35 drives the gear 34 to rotate, and the rotation of the gear 34 drives the racks 33 on both sides to move synchronously. The racks 33 also drive the slide 32 to slide along the sliding cavity 301, and the slide 32 also drives the base 36 and the fixed plate 37 to move. At this time, the fixed plates 37 on both sides simultaneously approach the workpiece placed on the top of the top plate 31. When the fixed plate 37 moves to one side of the workpiece, the user stops the power of the motor 35. Finally, the user turns on the power of the fan 38, and the fan 38 starts to work and blows wind. The wind is blown onto the workpiece through the air hole 370, and the workpiece gradually dissipates heat.

[0038] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention.
