Description

Technical Field

[0001] This utility model relates to the field of laser processing equipment technology, and in particular to a reflector assembly and a laser engraving machine. Background Technology

[0002] Laser engraving machines are widely used in industrial production. A laser engraving machine includes a laser emitter, a laser engraving head, and a two-dimensional planar movement mechanism. Medium to large-sized laser engraving machines use laser emitters that occupy a significant amount of space. Generally, the laser emitter is set up separately, and an optical path mechanism projects the laser light onto the laser engraving head. The laser engraving head is connected to the two-dimensional planar movement mechanism, which drives the laser engraving head to move in a plane while simultaneously engraving. The optical path mechanism requires reflectors to adjust the laser path to ensure that the laser light is projected onto the laser engraving head. The reflectors are generally mounted on the frame. When setting up the optical path, the frame needs to be adjusted so that the reflectors can reflect the laser light onto the correct optical path. Current frame designs are relatively complex, and adjusting the reflector positions is not straightforward. Summary of the Invention

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0029] The present invention will now be described in detail with reference to the accompanying drawings. Figures 1 to 5 As shown.

[0030] Example 1: See Figure 1 , Figure 2 A reflector assembly includes: a reflector and a horizontally arranged fixing plate. The fixing plate is connected to a vertically arranged support plate. A reflector mounting seat is provided on one side of the support plate. The side of the reflector mounting seat away from the support plate is detachably connected to the reflector. The other side of the support plate is provided with a connecting bolt and a through hole that mates with the connecting bolt. The reflector mounting seat is provided with a threaded hole corresponding to the connecting bolt. The bolt thread passes through the through hole and connects to the threaded hole. An adjusting spring is sleeved on the bolt thread. One end of the adjusting spring abuts against the support plate, and the other end of the adjusting spring abuts against the head of the connecting bolt. Three adjusting bolts are connected to the other side of the support plate. One end of the adjusting bolt passes through the support plate and abuts against the reflector mounting seat.

[0031] In application, the reflector assembly is positioned in the optical path of the laser engraving machine to reflect and alter the laser's path. The laser beam is projected onto the reflector and reflected. When the reflected light path deviates from the original preset path, the reflector needs adjustment. Adjustment methods generally fall into two categories: 1. Reflection point position adjustment: This primarily involves adjusting the reflector's position using three adjusting bolts simultaneously. The reflector mounting base is connected to the connecting bolts, whose heads are pushed outward by adjusting springs. These springs, through the connecting bolts, push the reflector mounting base towards the support plate or cause it to move. The ends of the three adjusting bolts abut against the reflector mounting base; the extension and retraction of these bolts guides the movement of the reflector mounting base, thus adjusting the reflection point's position and ensuring it is centered on the reflector. 2. Reflective surface adjustment: The three adjusting bolts have three contact points with the reflector mounting base, defining a plane. Adjusting each of the three adjusting bolts individually adjusts the reflector's surface. The reflector assembly can be adjusted using only 3 adjusting bolts. The overall structure is simple and the adjustment is quick and easy.

[0032] See Figure 1 , Figure 2 as well as Figure 5 The fixing plate is connected to a protective cover, which is located on the side of the reflector fixing base away from the support plate. The protective cover is L-shaped or V-shaped. In this embodiment, the protective cover is set to L-shaped, and light holes for laser to pass through are opened on both sides of the protective cover.

[0033] By installing a protective shield, the front of the reflector is shielded, thus protecting it from external interference. An aperture is also included to allow laser light to pass through. To increase the protection range of the shield, at least one side of the shield is connected to a protective plate, such as... Figure 1 , Figure 5 As shown; in specific implementation, the reflector needs to be inserted and installed from one side of the reflector mounting base, and the protective cover does not need to be set on the corresponding side to prevent it from hindering the installation and removal of the reflector.

[0034] See Figure 1 , Figure 2 To provide greater protection for the reflector mount, a top plate is connected to the upper end of the protective cover. The top plate covers the reflector mount, protecting it from interference from above. Exemplarily, to facilitate the manufacture of the protective cover, mounting plate, top plate, and protective plate, in this embodiment, the mounting plate, protective cover, protective plate, and top plate are integrally formed; this can be achieved through stamping and bending of sheet metal.

[0035] See Figure 3 , Figure 5The reflector mounting base has a snap-fit ​​structure on the side away from the support plate. The upper and lower ends of the reflector mounting base are respectively provided with L-shaped snap-fit ​​blocks, and the snap-fit ​​blocks and the reflector mounting base form a snap-fit ​​groove for installing the reflector.

[0036] When the reflector is installed in the reflector mounting base, it can be inserted into the side through the designated slot, the width of which matches the width of the reflector; similarly, when removing the reflector, it can also be moved out from the side of the reflector mounting base, making disassembly and assembly convenient.

[0037] The reflector is a relatively precise optical instrument. To prevent its surface from being contaminated or damaged, especially the central working area, and also to facilitate the movement of the reflector, a patch is attached to one side. By moving the patch, the reflector can be moved.

[0038] See Figure 3 , Figure 4 as well as Figure 5 The support plate is connected to a tightening bolt. The reflector mounting base is provided with a threaded through hole that mates with the tightening bolt. The support plate is provided with a through hole that mates with the tightening bolt. One end of the tightening bolt passes through the support plate and the reflector mounting base and abuts against the patch. The tightening bolt is threadedly connected to the reflector mounting base.

[0039] See Figure 3 as well as Figure 5 The reflector and reflector mounting base are connected by a plug-in structure. To prevent the reflector from shifting due to external forces during use, this embodiment includes a tightening bolt to assist in fixing the reflector and prevent displacement due to external influences. In a specific configuration, the tightening bolt is threadedly connected to the reflector mounting base. By rotating the tightening bolt, its position can be adjusted. The tightening bolt abuts against the patch, pushing the patch and the reflector so that the edge of the reflector abuts against the locking block, thereby fixing the reflector.

[0040] See Figures 1 to 5 To facilitate fixing the reflector assembly to the body of the laser engraving machine, a support unit is connected to the lower end of the fixing plate. The support unit includes a support rod, and a support plate is connected to the upper end of the support rod. The lower end of the support plate is provided with several threaded holes. The fixing plate and the support plate are provided with through holes corresponding to the threaded holes. The support plate is connected with a fixing bolt. One end of the fixing bolt passes through the support plate and the fixing plate and is threadedly connected to the support plate.

[0041] Support rods are used to support the fixed plate. To simplify the connection structure, this embodiment employs a clamping technique, where a support plate is connected to the support plate via a support disc, clamping the fixed plate within it. This not only fixes the support plate to the fixed plate but also connects the support rod to the fixed plate via the support disc. Of course, other structures can also be used, such as directly connecting the support rod to the fixed plate using threaded connections, welding, or other methods.

[0042] See Figure 5 The lower end of the support rod is connected to a height adjusting cylinder. The upper end of the height adjusting cylinder has an insertion hole that mates with the support rod. Several locking screws are threaded onto the side of the height adjusting cylinder. One end of the locking screw is inserted into the insertion hole and abuts against the support rod. The lower end of the height adjusting cylinder is provided with an upper connecting plate. The left and right sides of the upper connecting plate are respectively provided with transversely arranged transverse adjusting grooves. Below the upper connecting plate is a lower connecting plate. The lower connecting plate has threaded holes that mate with the transverse adjusting grooves. A connecting bolt is provided in the transverse adjusting groove. One end of the connecting bolt passes through the transverse adjusting groove and is inserted into the threaded hole to be threadedly connected to the lower connecting plate. The front and rear sides of the lower connecting plate are respectively provided with longitudinally arranged longitudinal adjusting grooves.

[0043] When adjusting the reflector assembly, a relatively large movement of the entire assembly is required in the initial stage to move the reflector to a predetermined position. To facilitate adjustment, this embodiment, for example, employs a three-dimensional movement structure. Vertical adjustment utilizes a plug-in structure between a support rod and a height adjustment cylinder. The support rod can move up and down along the plug-in hole of the height adjustment cylinder. After the adjusted height is achieved, the support rod is tightened with locking screws. Left-right and front-back adjustments are achieved by providing horizontal and vertical adjustment slots on the upper and lower connecting plates, respectively. The lower connecting plate can move vertically relative to the laser engraving machine body via the vertical adjustment slot, and the upper connecting plate can move horizontally relative to the lower connecting plate via the horizontal adjustment slot.

[0044] Example 2: See Figure 6 , Figure 7 A laser engraving machine includes a laser emitter 200 and a laser engraving head 300, with a plurality of the aforementioned reflector assemblies 100 disposed between the laser emitter 200 and the laser engraving head 300.

[0045] Laser engraving machines can be equipped with different numbers of reflector assemblies 100 depending on the optical path design.

[0046] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
