[0030] In this embodiment, the length of the workpiece is the side length of the longest side of the workpiece, the width of the workpiece is the side length of the second longest side of the workpiece, and the thickness of the workpiece is the side length of the shortest side of the workpiece. Taking a lighter as an example for the positioned workpiece, the length of the lighter is the side length of the longest side of the lighter, the width of the lighter is the side length of the second longest side of the lighter, and the thickness of the lighter is the side length of the shortest side of the lighter. And the two surfaces with the largest area of the lighter are set as the front and back surfaces, the two surfaces with the smallest area are set as the bottom surfaces, and the two surfaces with a medium area are set as the side surfaces. As a small fire starter, the lighter is mainly used for lighting cigarettes, cooking, and other fire starting purposes. Nowadays, the patterns on the lighter shell are becoming more and more diverse, and buyers also tend to add personalized logos to the lighter. Whether adding pattern content or personalized logos to the shell, a laser engraving device is often used to engrave the lighter shell to extend the retention time of the device pattern and personal logo on the lighter shell. When using a laser engraving device to engrave the lighter shell, the lighter needs to be fixed. In addition, when engraving some complex patterns, the patterns cover multiple surfaces of the lighter. Therefore, a positioning fixture is needed to meet the positioning and processing requirements of multiple surfaces of the lighter.

[0031] The following refers to Figures 1 to 3 A multi - surface positioning fixture according to an embodiment of the present utility model is described, which includes a fixture base plate 1 and a multi - surface positioning part 2. The multi - surface positioning part 2 is arranged on the fixture base plate 1. The fixture base plate 1 is used to be fixed on a laser engraving device, and the multi - surface positioning part 2 is used to fix the workpiece. A multi - surface positioning groove 3 is arranged in the middle of the multi - surface positioning part 2, and a positioning plate 4 for placing the workpiece is arranged in the multi - surface positioning groove 3. The lighter can be placed flat or sideways on the upper surface of the positioning plate 4 or between the positioning plates 4. At this time, the laser engraving device can process the front and back surfaces and the two side surfaces of the lighter located on the side. In addition, a bottom card slot 6 is arranged on the fixture base plate 1 at the bottom of the multi - surface positioning groove 3. The bottom card slot 6 is used to position the bottom of the workpiece. The lower bottom surface of the lighter is inserted into the bottom card slot 6, and the laser engraving device can process the upper bottom surface of the lighter. The upper bottom surface of the lighter is inserted into the bottom card slot 6, and the laser engraving device can process the lower bottom surface of the lighter. Therefore, the multi - surface positioning fixture provided by the above - mentioned embodiment of the present utility model can provide multiple installation and positioning methods for the lighter. In different positioning methods, different surfaces of the lighter are exposed, meeting the needs of the laser engraving device for multi - surface processing.

[0032] In one embodiment, when the workpiece is placed in the multi-faceted positioning groove 3 in different states, the machining surfaces of the workpiece are at the same height. The different states of the workpiece are three placement methods of the workpiece lying flat, placed sideways, and standing upright in the multi-faceted positioning groove 3. The machining surfaces of the workpiece being at the same height means that when the workpiece is in each placement method, the height of the topmost surface of the workpiece remains the same. In this embodiment, when the lighter is placed in different ways, the front and back, sides, and bottom of the lighter are flush with the opening surface of the multi-faceted positioning groove 3, and multiple machining surfaces of the lighter can be kept at the same height. During laser processing, there is no need to adjust the height of the laser equipment, improving the efficiency and quality of laser processing.

[0033] In one embodiment, it further includes at least one hinge avoidance groove 7. The hinge avoidance groove 7 is provided on the side wall of the multi-faceted positioning groove 3 between the positioning plates 4. When the workpiece is a lighter, there is a hinge on the side wall of the lighter. Generally, the hinge is provided on the side wall with a smaller area of the lighter. Therefore, when the hinge avoidance groove 7 is provided on the side wall of the multi-faceted positioning groove 3 between the two positioning plates 4, it provides a placement space for the hinge on the side wall of the lighter, avoiding the hinge from affecting the installation and positioning of the lighter. When there are multiple hinge avoidance grooves 7, the hinge avoidance grooves 7 provided on the same side wall of the multi-faceted positioning groove 3 are symmetric along the midline of the side wall of the multi-faceted positioning groove 3, or the hinge avoidance grooves 7 are oppositely provided on the side walls on both sides of the multi-faceted positioning groove 3, and the opening positions of the avoidance grooves 6 on different side walls are the same. Since the hinge on the lighter is generally located in the upper half of the lighter, when changing the machining surface of the lighter, the lighter needs to be flipped, and the position of the lighter hinge in the multi-faceted positioning groove 3 changes after flipping. The above-mentioned multiple hinge avoidance grooves 7 provide multiple possibilities for the placement position of the lighter.

[0034] In one embodiment, referring to Figure 2 , a side card slot 5 is further provided in the multi-faceted positioning groove 3. The groove width of the side card slot 5 is equal to the thickness of the workpiece, facilitating the positioning of the workpiece. Further, the side card slot 5 is provided on the positioning plate 4. On each positioning plate 4, the side card slot 5 is provided at the same position. The workpiece can be positioned simultaneously by multiple positioning plates 4, further improving the positioning effect of the workpiece. In this embodiment, when the lighter is inserted into the side card slot 5, the side of the lighter can be exposed, limiting the lighter, and the laser device processes the two sides of the lighter.

[0035] In one embodiment, the positioning plate 4 is arranged on the opposite inner walls on both sides of the multi-faceted positioning groove 3. The distance between the two opposite inner walls of the multi-faceted positioning groove 3 is equal to the length of the workpiece. In this embodiment, when the lighter is placed flat on the upper surface of the positioning plate 4 and the lighter is placed sideways into the side card slot 5, since the distance between the two opposite inner walls of the multi-faceted positioning groove 3 is equal to the length of the workpiece, the upper and lower bottom surfaces of the lighter can be attached to the inner walls of the multi-faceted positioning groove 3, realizing precise limit for the lighter, and the laser device processes the front, back and two sides of the lighter.

[0036] In one embodiment, the height difference between the upper surface of the positioning plate 4 and the upper surface of the multi-faceted positioning groove 3 is not greater than the thickness of the workpiece. In this embodiment, the workpiece is set as a lighter. When the lighter is placed above the positioning plate 4 for positioning, the front and back sides of the lighter can extend beyond the notch position of the multi-faceted positioning groove 3, facilitating the processing of the surface by the laser engraving device and the taking of the lighter.

[0037] In one embodiment, the height difference between the bottom surface of the side card slot 5 and the upper surface of the multi-faceted positioning groove 3 is not greater than the width of the workpiece, so that when the lighter is positioned in the side card slot 5, the side of the lighter can extend beyond the notch position of the multi-faceted positioning groove 3, facilitating the processing of the surface by the laser engraving device and the taking of the lighter.

[0038] In one embodiment, the sum of the depth of the bottom card slot 6 and the depth of the multi-faceted positioning groove 3 is not greater than the length of the workpiece, so that when the lighter is positioned in the bottom card slot 6, the bottom surface of the lighter perpendicular to the length direction can extend beyond the notch position of the multi-faceted positioning groove 3, facilitating the processing of the surface by the laser engraving device and the taking of the lighter.

[0039] In one embodiment, referring to Figure 1 , the multi-faceted positioning part 2 is fixed in the middle of the fixture bottom plate 1. An extension part is arranged around the multi-faceted positioning part 2 on the fixture bottom plate 1, and a fixing groove 8 is arranged on the extension part. The positioning fixture can be fixed in the laser device through the fixing groove 8. In this embodiment, the fixing groove 8 is a strip-shaped installation groove, and an installation strip is arranged around the inside of the groove. The fixture bottom plate 1 and the laser device can be fixed through a bolt assembly. When fixing, the nut can be installed on the installation strip in the fixing groove 8.

[0040] The working principle of the multi-faceted positioning fixture provided in this embodiment is as follows: First, install the multi-faceted positioning fixture on the laser device through the fixing groove 8. Taking a lighter as an example, insert the bottom surface of the lighter into the bottom card slot 6 at the bottom of the multi-faceted positioning slot 3 for positioning. After the lighter is positioned in the bottom card slot 6, the laser device processes the upper bottom surface of the lighter. After processing, the lighter can be flipped to process the opposite lower bottom surface, thereby completing the processing of the upper and lower bottom surfaces of the lighter; place the lighter flat on the two opposing positioning plates 4 in the multi-faceted positioning slot 3, and place the lighter hinge into the hinge avoidance slot 7. The laser device processes the lighter. Since the length of the side of the multi-faceted positioning slot 3 without the installed positioning plate 4 is the same as the length of the lighter, and the distance between the top surface of the positioning plate 4 and the top surface of the multi-faceted positioning slot 3 is the same as the thickness of the lighter, when the lighter is positioned on the positioning plate 4, the laser device processes the front surface of the lighter. After processing, the lighter can be flipped to process the reverse side of the lighter, that is, complete the processing of the front and back sides of the lighter; finally, insert the two bottom surfaces of the lighter into the side card slots 5 on the positioning plate 4. Since the height difference between the bottom surface of the side card slot 5 and the upper surface of the multi-faceted positioning slot 3 is equal to the width of the workpiece, when the lighter is positioned in the side card slot 5, the laser device processes the side surface of the lighter. After processing, the lighter can be flipped to process the other opposite side surface of the lighter, that is, complete the processing of the two side surfaces of the lighter. Therefore, the multi-faceted positioning fixture of the present application provides multiple ways for positioning workpieces such as lighters, can meet the needs of polyhedron processing, and this positioning fixture has accurate positioning, meets the requirements of positioning accuracy, and can improve the quality of laser processing.
