[0002] Currently, in the manufacturing of automotive headlights, due to different needs, it is necessary to manufacture automotive headlights with spherical lenses. Spherical lenses are usually made using injection molding. However, spherical lenses are very fragile and cannot be touched. In order to remove the lens, a connecting rod needs to be injection molded on both sides of the lens for material removal. However, before using the lens, the connecting rod needs to be cut off. Currently, the laser cutting method is commonly used to cut off the connecting rod.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 4The laser cutting device for automotive headlight lenses in this embodiment includes a processing box 1 and a door 2 hinged to the outside of the processing box 1. A laser cutting mechanism 3 extending into the outside of the processing box 1 is provided, and a rotating mechanism 4 for realizing automatic and precise rotation of the lens is provided inside the processing box 1.

[0027] The laser cutting mechanism 3 includes an electric push rod 31 fixedly mounted on the top of the processing box 1. A mounting box 32 is fixedly connected to the output end of the electric push rod 31. A drive motor 33 is fixedly mounted on the inner top wall of the mounting box 32. An adjusting gear 34 is fixedly connected to the output shaft of the drive motor 33. Two toothed plates 35 are externally meshed with the adjusting gear 34, and a laser emitter 37 is mounted on the outside of the toothed plates 35. The electric push rod 31 drives the mounting box 32 to move up and down, flexibly adjusting the cutting height of the laser emitter 37 to meet the needs of different cutting scenarios. Simultaneously, the cutting process takes place inside the processing box 1, and the door 2, hinged to the outside of the processing box 1, provides protection, preventing laser injury and ensuring the safety of the operator.

[0028] Specifically, a connecting rod 36 is fixedly connected between the toothed plate 35 and the laser emitter 37, and the mounting box 32 has an internal moving opening adapted to the toothed plate 35 and the connecting rod 36. The two toothed plates 35 are symmetrically distributed on the outside of the adjusting gear 34, and there are two sets of laser emitters 37, which are sequentially and fixedly connected to opposite sides of the two sets of toothed plates 35. By driving the transmission structure of the adjusting gear 34 and the toothed plate 35 through the drive motor 33, the spacing of the laser emitters 37 can be flexibly and precisely adjusted to meet the cutting requirements of lenses of different sizes, improving the versatility and applicability of the device.

[0029] It should be noted that two guide shafts 39 are fixedly connected inside the mounting box 32, and the two guide shafts 39 are symmetrically distributed left and right inside the mounting box 32. Connecting ears 38 are fixedly connected to the back of each of the two toothed plates 35, and the connecting ears 38 are slidably connected to the outside of the guide shafts 39. The slidable connection between the two symmetrically distributed guide shafts 39 inside the mounting box 32 and the connecting ears 38 fixedly connected to the back of the toothed plates 35 guides and stabilizes the movement of the toothed plates 35, making the movement of the laser emitter 37 smoother, reducing errors during the cutting process, and improving cutting accuracy.

[0030] Please see Figure 1 and Figure 4In this embodiment, the rotating mechanism 4 includes a mounting plate 41 fixedly connected to the bottom of the processing box 1 and a servo motor 42 fixedly mounted on the top of the mounting plate 41. A rotating shaft 44 extending into the processing box 1 is rotatably connected inside the mounting plate 41. A gear disk 45 is fixedly mounted on the outside of the rotating shaft 44, and a negative suction stage 46 is fixedly connected to the top of the rotating shaft 44. A transmission gear 43 meshing with the gear disk 45 is fixedly connected to the output shaft of the servo motor 42. By employing a transmission structure where the servo motor 42 drives the transmission gear 43 and the gear disk 45, automatic and precise rotation of the lens can be achieved, the rotation angle can be precisely controlled, the requirements of different cutting angles can be met, and the cutting quality and efficiency can be improved.

[0031] The machining box 1 has a bearing that is compatible with the rotating shaft 44, and the negative suction table 46 is rotatably connected to the inside of the machining box 1.

[0032] Specifically, the negative suction platform 46 has a number of adsorption holes inside, which are distributed at equal intervals within the platform. The negative suction platform 46 is connected to an external vacuum pump. Once started, the vacuum pump begins to extract air from inside the negative suction platform 46 and its connected pipes. The negative suction platform 46 has a sealed structure to effectively isolate the internal space from the outside atmosphere during vacuum pump operation, thus creating a relatively enclosed space. As the vacuum pump continuously extracts air, the air inside the negative suction platform 46 gradually decreases, and the air pressure gradually drops, creating a negative pressure environment. When a negative pressure is formed inside the negative suction platform 46, a pressure difference is created between the external atmospheric pressure and the internal pressure. When a car headlight lens is placed on the negative suction platform 46, due to the pressure difference, external air attempts to enter the negative suction platform 46 through the tiny gap between the lens and the surface to balance the pressure. During this process, the air exerts a downward pressure on the lens, causing the lens to be firmly adhered to the negative suction stage 46.

[0033] It should be noted that two support seats 5 are fixedly connected to the bottom of the processing box 1, and the two support seats 5 are symmetrically distributed on the bottom of the processing box 1. The two support seats 5 symmetrically distributed on the bottom of the processing box 1 provide stable support for the device and ensure the stability of the cutting process.

[0034] The working principle of the above embodiments is as follows:

[0035] In use, the automotive headlight lens to be cut is placed on the negative suction platform 46. The negative suction platform 46 has several equally spaced suction holes inside. The negative pressure generated through these holes firmly adheres the lens to the platform, preventing displacement during cutting. According to the cutting requirements, the controller activates the servo motor 42. The output shaft of the servo motor 42 drives the transmission gear 43 to rotate. The rotation of the transmission gear 43 drives the gear disc 45 to rotate, which in turn drives the rotating shaft 44 to rotate, causing the negative suction platform 46 and the lens on it to rotate. This achieves automatic and precise rotation of the lens to meet the cutting requirements. To meet the needs of different cutting angles; when it is necessary to cut automotive headlight lenses of different sizes and adjust the spacing of the laser emitters 37, the drive motor 33 is started to drive the adjusting gear 34 to rotate, which will cause the two toothed plates 35 to move in opposite directions. As the toothed plates 35 move, the two sets of laser emitters 37 move closer or further apart, thereby adjusting the spacing of the laser emitters 37. The controller starts the extension and retraction of the electric push rod 31. The output end of the electric push rod 31 drives the mounting box 32 to move up and down, which in turn drives the laser emitters 37 to move up and down, adjusting the laser cutting height.

Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply.
