[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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 utility model.

If "first," "second," etc., are used in the description, they are only for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the sequential relationship of the indicated technical features.

[0021] In the description of this utility model, unless otherwise explicitly defined, the terms "setting", "installation", "connection", etc. should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in combination with the specific content of the technical solution.

[0022] Please refer to Figures 1 to 3 As shown, in one aspect, this utility model provides a laser engraving device, including a feeding module 100, a laser engraving module 200, and a detection module 300; the feeding module 100 includes a fixture 110 and a first rotating member 120, the axis of the first rotating member 120 extending along a first direction, the fixture 110 being adapted to carry a product and rotate under the drive of the first rotating member 120; the laser engraving module 200 includes a laser head 210, the laser head 210 being disposed on a first circumferential side of the fixture 110 and facing the product; the detection module 300 includes a detection camera 310, the detection camera 310 being disposed on a second circumferential side of the fixture 110 and the detection field of view of the detection camera 310 facing the product, the detection camera 310 being adapted to detect the image laser-engraved by the laser head 210; the first side and the second side are set at an angle relative to the axis of the first rotating member 120.

[0023] According to the laser engraving device of this utility model embodiment, the product is placed and fixed in the fixture 110, and the laser head 210 emits laser to the surface of the product to laser engrave a pattern. The engraved pattern is rotated to the detection module 300 side by the first rotating member 120, and the detection camera 310 acquires the pattern to determine the pattern quality. While the detection camera 310 acquires the image, the laser head 210 can simultaneously laser engrave patterns on the remaining surfaces of the product.

[0024] According to the laser equipment of this utility model embodiment, the first rotating component 120 drives the fixture 110 to rotate the product. While the laser engraving module 200 is engraving, the detection module 300 performs quality inspection on the laser-engraved pattern, thereby improving product production efficiency.

[0025] In this embodiment, the angle between the first side and the second side can be adjusted based on the pattern arrangement on the product surface. For example, if the product needs to be laser-engraved with four patterns spaced 90 degrees apart, the clamp between the first side and the second side and the axis of the first rotating part 120 can be a multiple of 90 degrees, such as 90 degrees, 180 degrees or 270 degrees. Of course, when the pattern on the product surface is continuous, the angle between the first side and the second side can be set arbitrarily.

[0026] In this embodiment, the first rotating component 120 can use a stepper motor or a servo motor as a power source, and the rotational motion of the motor output shaft can be converted into the rotational motion of the fixture 110 through a transmission mechanism (such as a worm gear, gear, etc.).

[0027] In some embodiments, combined with Figure 2 and Figure 3 As shown, the laser engraving module 200 also includes a first lifting component 220, the movable end of which is connected to the laser head 210, suitable for driving the laser head 210 to move up and down along a first direction. The relative height between the laser head 210 and the product can be adjusted along the Z direction shown in the figure to adapt to the laser engraving needs of different product specifications and patterns of different heights.

[0028] In this embodiment, the first lifting component 220 is a slide module, but it can also be a lead screw module, cylinder, etc.

[0029] In some embodiments, combined with Figure 1 As shown, the detection module 300 also includes a reflecting prism 320, which is disposed directly below the detection camera 310 along a first direction. The lens of the detection camera 310 faces the reflecting prism 320, and the detection field of view of the detection camera 310 is deflected by the reflecting prism 320 to cover the pattern on the product surface.

[0030] Understandably, since the optical path of the detection camera 310 must be straight, the detection camera 310 must be installed on the side of the fixture 110 without the reflection prism 320. Related components of the detection camera 310 (such as supplementary light source) need to be arranged radially in front of the detection camera 310 along the first rotating member 120, which greatly increases the volume occupied by the detection module 300 on the side of the fixture 110.

[0031] By setting the reflective prism 320, the detection camera 310 can be installed upward along the first direction. The relevant components of the detection camera 310 do not need to extend to the side of the fixture 110. The projected area of ​​the entire detection module 300 on the horizontal plane is greatly reduced, thus reducing the area occupied by the laser engraving equipment on the horizontal plane.

[0032] In some embodiments, combined with Figure 1As shown, the detection module 300 also includes a second lifting component 330. The movable end of the second lifting component 330 is connected to the detection camera 310, and is adapted to drive the detection camera 310 to move up and down along a first direction. Through the second lifting component 330, a corresponding height for the detection camera 310 can be preset for each product. When changing products, the system automatically calls the recipe and drives the detection camera 310 to the preset optimal position, without the need for manual adjustment.

[0033] In this embodiment, the second lifting component 330 is a slide module, but it can also be a lead screw module, cylinder, etc.

[0034] In some embodiments, combined with Figures 1 to 4 As shown, the feeding module 100 also includes a first linear module 130. The first linear module 130 extends along a second direction, which is perpendicular to the first direction. The movable end of the first linear module 130 is connected to the fixture 110. The first linear module 130 is provided with a laser engraving station and a feeding station. The laser engraving station is located at the intersection of the axis of the laser head 210 and the axis of the detection field of view. The feeding station is away from the laser engraving module 200 and is located on the user side.

[0035] In this embodiment, the user places the product onto the fixture 110 at the loading station and fixes it in place. Driven by the first linear module 130, the fixture 110 carries the product to the laser engraving station. The laser engraving module 200 and the detection module 300 then start to complete the laser engraving and detection of the product. The first linear module 130 keeps the user away from the laser engraving module 200, improving user safety.

[0036] In this embodiment, the first linear module 130 is a slide module, but it can also be a lead screw module, cylinder, etc.

[0037] In some embodiments, combined with Figure 4 and Figure 5 As shown, the laser engraving equipment also includes a housing 410 and an isolation door assembly 420. The housing 410 covers the feeding module 100, the laser engraving module 200, and the detection module 300. The housing 410 has an opening that connects to the outside world. The opening and the laser engraving module 200 are respectively located on opposite sides of the fixture 110. The isolation door assembly 420 includes an isolation door plate 421 and an isolation drive member 422. The isolation door plate 421 is adapted to open and close the opening under the drive of the isolation drive member 422.

[0038] In this embodiment, the opening facilitates product loading and unloading, while the closure of the isolation door panel 421 creates a sealed space in the housing 410, preventing dust from the outside air from falling on the product surface and affecting the quality of the laser engraving pattern or causing misjudgment in the inspection. It also reduces the impact of external vibrations on the high-precision laser head 210 and the inspection camera 310 to a certain extent. Furthermore, it avoids interference from changes in external light (such as workshop lights and sunlight) on the imaging of the inspection camera 310, ensuring the consistency and reliability of visual inspection.

[0039] In this embodiment, the isolation door assembly 420 is typically interlocked with the equipment's control system, meaning that the laser engraving module 200 can only start working when the isolation door panel 421 is completely closed, preventing safety accidents caused by misoperation.

[0040] In some embodiments, combined with Figure 3 As shown, the fixture 110 includes a positioning clamp 111 and a clamp base 112. The positioning clamp 111 is detachably connected to the clamp base 112 and is suitable for clamping products.

[0041] In this embodiment, different positioning clamps 111 are used to adapt to different types of products, such as lenses of different sizes, thermos cups, etc.

[0042] In this embodiment, the positioning structure between the positioning fixture 111 and the product can be in the form of a pressure plate, a claw, or a magnetic attraction.

[0043] In some embodiments, combined with Figure 1 As shown, the laser engraving equipment also includes a frame 500, which has multiple parallel production stations. Each production station is equipped with a feeding module 100, a laser engraving module 200, and a detection module 300. By setting up multiple production stations, production efficiency is improved, and multiple production stations can be used simultaneously for laser engraving different products.

[0044] In this embodiment, three production stations can be set up, and the specific number can be adjusted based on actual needs.

[0045] In some embodiments, combined with Figures 1 to 5 As shown, the laser engraving equipment also includes a dust removal pipe 600, with the air inlet of the dust removal pipe 600 facing the product on the fixture 110, and the air outlet of the dust removal pipe 600 connected to an external dust collection device 700.

[0046] The laser head 210 instantly removes dust, ensuring that each laser strike is applied to a clean product surface, resulting in clear, uniform, and high-quality laser engraving patterns, effectively improving product yield. It also provides a clean air environment and field of view for the inspection camera 310, ensuring the authenticity and reliability of the acquired images, thereby guaranteeing the accuracy of quality inspection results. Furthermore, it effectively reduces the dust concentration inside the equipment, significantly reducing maintenance frequency and costs, protecting core components, and extending the overall service life of the machine.

[0047] On the other hand, this utility model embodiment also provides a lens production line, including the laser engraving equipment as described in the above embodiment.

[0048] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
