Description

Technical Field

[0001] This utility model relates to the field of laser marking machine technology, and in particular to a positioning mask type laser marking machine. Background Technology

[0002] A laser marking machine is a device that uses a laser beam to permanently mark the surface of various materials. By focusing and moving a high-energy laser beam, the desired graphic or textual markings are formed on the material surface. In industries such as toys and handicrafts, laser marking machines are commonly used to engrave patterns and text, enhancing the artistic value and aesthetic appeal of products.

[0003] In the typical laser marking process, laser marking machines usually rely on moving the product or adjusting the scanning path of the laser beam to cover the entire area to be marked. However, frequent product movement or adjustment of the laser beam scanning path not only increases the structural complexity of the equipment but may also lead to a decrease in marking accuracy, making it difficult to ensure the accuracy and consistency of the marking. Utility Model Content

[0004] Based on this, the present invention provides a positioning mask type laser marking machine, which has a simple structure and is easy to use. The lifting cylinder drives the carrier frame to move upward to abut against the floating pressure plate. The floating pressure plate accurately blocks the areas on the product that do not need to be marked, while the second through hole exposes the areas on the product that need to be marked, which facilitates the marking head to engrave. There is no need for a complex drive structure to move the product or adjust the scanning path of the laser beam, which effectively ensures the marking accuracy and consistency.

[0005] To achieve the objectives of this utility model, the following technical solution is adopted:

[0025] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0026] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0028] Please see Figures 1 to 4 The positioning mask laser marking machine according to one embodiment of the present utility model includes a body 10, a clamping assembly 20 mounted on the body 10, a masking assembly 30 mounted on the top of the clamping assembly 20, and a marking assembly 40 mounted on one side of the clamping assembly 20.

[0029] The body 10 includes a base 11 and a cover 12 mounted on top of the base 11.

[0030] The clamping assembly 20 includes a vertical plate 21 mounted on the top of the base 11, a support base 22 slidably connected to one side of the vertical plate 21, a bearing frame 23 mounted on the top of the support base 22, a plurality of suction nozzles 24 evenly spaced inside the bearing frame 23, and a lifting cylinder 25 mounted below the support base 22. The bearing frame 23 is used to hold the product to be marked, and the suction nozzles 24 are used to hold the product in place. The cylinder body of the lifting cylinder 25 is fixedly connected to the base 11, and the piston rod of the lifting cylinder 25 is connected to the support base 22. The lifting cylinder 25 drives the support base 22 and the bearing frame 23 to move up and down along the vertical plate 21.

[0031] In this embodiment, as Figure 4 As shown, the support base 22 is slidably connected to the upright plate 21 via the guide rail pair 220.

[0032] The shielding assembly 30 includes a fixed plate 31 fixedly installed on the top of the upright plate 21, floating pressure plates 32 parallel to and spaced below the fixed plate 31, and a plurality of springs 33 connecting the fixed plate 31 and the floating pressure plates 32. The floating pressure plates 32 are used to elastically abut against the top of the support frame 23.

[0033] Specifically, the fixed plate 31 has a first through hole 310 in the middle and the floating pressure plate 32 has a second through hole 320 in the middle. Both the first through hole 310 and the second through hole 320 correspond to the middle of the bearing frame 23.

[0034] In this embodiment, the opening area of ​​the second through hole 320 is smaller than that of the support frame 23.

[0035] The marking assembly 40 includes a hand-cranked linear module 41 arranged vertically and a laser marking machine 42 mounted on the hand-cranked linear module 41. The laser marking machine 42 has a marking head 43, which is located directly above the fixed plate 31 and corresponds to the first through hole 310 and the second through hole 32. In actual operation, the product to be marked is first loaded into the carrier frame 23 and clamped by the suction nozzle 24 to ensure the positioning accuracy of the product. Then, the lifting cylinder 25 drives the carrier frame 23 to move upward until the top of the carrier frame 23 abuts against and presses the floating pressure plate 32. At this time, the floating pressure plate 32 precisely blocks the area on the product that does not need to be marked, and the second through hole 320 exposes the area on the product that needs to be marked. The laser beam emitted by the marking head 43 passes through the first through hole 310 and the second through hole 320 and engraves on the surface of the product, making it easier to achieve more refined and complex marking patterns and text. Compared with traditional laser marking machines, this invention does not require a complex drive structure to move the product or adjust the scanning path of the laser beam, effectively ensuring marking accuracy and consistency.

[0036] The aforementioned positioning mask laser marking machine has a simple structure and is easy to use. The lifting cylinder 25 drives the carrier frame 23 to move upward and abut against the floating pressure plate 32. The floating pressure plate 32 accurately blocks the areas on the product that do not need to be marked, while the second through hole 320 exposes the areas on the product that need to be marked, making it convenient for the marking head 43 to engrave. There is no need for a complex drive structure to move the product or adjust the scanning path of the laser beam, which effectively ensures the marking accuracy and consistency.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
