Description

Technical Field

[0001] This utility model relates to the technical field of laser engraving fixtures, and in particular to a laser engraving fixture and laser engraving equipment. Background Technology

[0002] Currently, many products require laser engraving on their surfaces to display the product's model, manufacturer, pattern, or other graphic information. Moreover, many products (such as the oil cup of an electronic atomizer) require laser engraving on at least two sides to allow the product's surface to display more information.

[0003] The existing laser engraving process is as follows: First, multiple products are manually placed into a special fixture, with one side of each product facing upwards. Then, the fixture is placed into a laser engraving machine, which then laser engraves one side of each product from top to bottom. After the laser engraving is completed, the fixture is manually rotated 180° so that the other side of each atomizing bullet faces upwards. Then, the laser engraving machine laser engraves the other side of each product from top to bottom.

[0004] Currently, manually flipping the entire special fixture 180° requires repeated disassembly and fixing of the fixture. Therefore, achieving the flipping of the special fixture is currently time-consuming and labor-intensive, resulting in low efficiency in double-sided laser engraving of products.

[0005] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0030] It should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0031] 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.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] Please refer to the following: Figures 1 to 4 This utility model provides a laser engraving fixture, which mainly includes a base 1, a positioning plate 2, and a pressure plate 3. The positioning plate 2 has at least one limiting groove 21, which is used to limit the position of the product 10. The pressure plate 3 and the positioning plate 2 are detachably connected. When the pressure plate 3 is connected to the positioning plate 2, the pressure plate 3 and the positioning plate 2 will jointly clamp the product 10 located within the limiting groove 21, preventing the product 10 from shaking during subsequent laser engraving operations. Furthermore, the positioning plate 2 is rotatably connected to the base 1, and the positioning plate 2 has at least two positioning positions when rotating relative to the base 1. Moreover, the positioning plate 2 is magnetically attracted to the base 1 when rotated to any of these positioning positions.

[0034] The application process of the laser engraving fixture in this embodiment is as follows: First, the product 10 to be laser engraved is placed into the limiting groove 21 of the positioning plate 2, and then the pressure plate 3 is covered. The pressure plate 3 and the positioning plate 2 together hold the product 10. Then, the laser engraving host performs engraving on one side of the product 10. After the engraving is completed, the positioning plate 2 is driven to rotate to another position, for example, the positioning plate 2 is driven to rotate 180° so that the other surface of the product 10 can face the laser engraving host. Then, the laser engraving host performs engraving on the other side of the product 10. After the engraving is completed, the positioning plate 2 is driven to return to the initial position so that the pressure plate 3 is above the positioning plate 2. At this time, the pressure plate 3 can be removed, and then the product 10, which has been engraved on multiple sides, is taken out from inside the positioning plate 2.

[0035] Specifically, this solution designs the positioning plate 2 to be rotatable, allowing multiple sides of the product 10, held by the pressure plate 3 and the positioning plate 2, to face the laser engraving host. This enables laser engraving operations on multiple sides of the product 10, including double-sided laser engraving. Furthermore, this solution uses magnetic attraction to position the positioning plate 2 at a designated location. This positioning method, while meeting the stability requirements for laser engraving, offers advantages such as simple structure and low cost. It also allows operators to quickly and accurately rotate the positioning plate 2 to the designated position, significantly improving the efficiency of double-sided laser engraving on the product 10.

[0036] Please refer to them again. Figures 1 to 4 In this embodiment, the positioning plate 2 is provided with multiple limiting grooves 21, allowing the positioning plate 2 to accommodate multiple products 10 at once, thereby improving the efficiency of laser engraving on the products 10. In fact, the pressure plate 3 is provided with multiple through first clearance holes 31, each corresponding to a limiting groove 21. By providing the first clearance holes 31, the laser engraving host can pass through the first clearance holes 31 and perform laser engraving on one surface of the product 10. Similarly, the side of the positioning plate 2 facing away from the pressure plate 3 is provided with multiple second clearance holes 24, each corresponding to a limiting groove 21 and extending into the limiting groove 21. By providing the second clearance holes 24, when the positioning plate 2 rotates 180°, the laser engraving host can pass through the second clearance holes 24 and perform laser engraving on another surface of the product 10.

[0037] Please refer to the following: Figure 3 and Figure 4The positioning plate 2 is fixed with multiple first magnets 4, and the base 1 is fixed with multiple second magnets 5. When the positioning plate 2 rotates to any positioning position, the multiple second magnets 5 and the multiple first magnets 4 attract each other in a one-to-one correspondence. This achieves the function of magnetic attraction between the positioning plate 2 and the base 1 when the positioning plate 2 rotates to any positioning position. Moreover, the design of magnetic attraction by multiple magnets can ensure high stability when the positioning plate 2 is positioned at any positioning position, which is conducive to improving the accuracy of laser engraving on the product 10.

[0038] Please refer to them again. Figure 3 and Figure 4 Two spaced first magnets 4 are fixed on the first side 22 of the positioning plate 2. Two spaced first magnets 4 are also fixed on the second side 23 of the positioning plate 2, which is opposite to the first side 22. The base 1 has a total of four second magnets 5 around the positioning plate 2. By arranging magnets around the positioning plate 2, it is beneficial to make the two positioning positions switched by rotating the positioning plate 2 by 180° more stable.

[0039] Please refer to the following: Figures 1 to 4 The base 1 specifically includes a base plate 11 and two spaced-apart upright plates 12. Both upright plates 12 are fixed to the base plate 11, and a positioning plate 2 is located between the two upright plates 12. The positioning plate 2 is rotatably connected to each of the two upright plates 12 via bearings. This split design of the base 1 facilitates a reliable rotatable connection between the base 1 and the positioning plate 2, and also helps reduce the manufacturing cost of the base 1. Based on this structural design of the base 1, each upright plate 12 is fixed with two of the aforementioned second magnets 5.

[0040] Please refer to them again. Figures 1 to 4 The positioning plate 2 has a rotating shaft plate 6 fixed at both the first side 22 and the second side 23. The two rotating shaft plates 6 are rotatably connected to the two upright plates 12 in a one-to-one correspondence via connecting bearings, thereby enabling the positioning plate 2 to rotate relative to the upright plates 12. In addition, at least one rotating shaft plate 6 is fixed with a handle 7 located on the outside of the upright plate 12. By providing this handle 7, the operator can operate the handle 7 to drive the positioning plate 2 to rotate, thereby improving the convenience of operation for the operator and thus improving the efficiency of laser engraving on the product 10.

[0041] Please refer to them again. Figure 3 and Figure 4The positioning plate 2 is provided with a positioning groove 25 whose size is adapted to the shape of the pressure plate 3. The bottom of this positioning groove 25 has multiple limiting grooves 21. By providing this positioning groove 25, the pressure plate 3 can be more accurately installed on the positioning plate 2, thereby improving the reliability of the pressure plate 3 and the positioning plate 2 simultaneously clamping multiple products 10, and thus improving the accuracy of the laser engraving host in engraving multiple products 10. Furthermore, the bottom of the positioning groove 25 and the pressure plate 3 are also magnetically attracted to each other. The magnetic installation of the pressure plate 3 on the positioning plate 2 has the advantage of easy assembly and disassembly, which also helps to improve work efficiency. Preferably, the bottom of the positioning groove 25 is provided with multiple third magnets 8, and the pressure plate 3 is provided with multiple fourth magnets (not shown in the figure). When the pressure plate 3 is installed in the positioning groove 25, the multiple third magnets 8 and the multiple fourth magnets attract each other one-to-one, thus specifically realizing the function of the pressure plate 3 being magnetically installed on the positioning plate 2.

[0042] This embodiment also provides a laser engraving device, which includes a laser engraving main unit and the aforementioned laser engraving fixture. The base 1 of the laser engraving fixture is fixed on the laser engraving main unit, and the laser engraving main unit is used to perform laser engraving operations on multiple products 10 located on the laser engraving fixture. Since the laser engraving device of this embodiment uses the aforementioned laser engraving fixture, the laser engraving device of this embodiment can efficiently complete double-sided laser engraving operations on multiple products 10.

[0043] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
