[0002] As is known, laser cutting is to use a focused high-power density laser beam to irradiate the workpiece, so that the irradiated material quickly melts, vaporizes or reaches the ignition point, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the workpiece. It is one of the thermal cutting methods for cutting workpieces; For example, the authorization announcement number is CN111805079 B, the authorization announcement date is 2024.07.05, and the name is a laser cutting device, which includes a workbench, a cutting device, a pulling device, a dust extraction device, and a feeding device.

DETAILED DESCRIPTION

[0018] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, and use. It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0019] Example 1, reference Figure 1-10: This embodiment provides a technical solution: a laser cutting device for processing automobile headlight lenses, comprising an equipment body 1, and a laser cutting head 3 arranged above the inside of the equipment body 1 for cutting the headlight lens, a lens fixing mechanism 2 for fixing the headlight lens is installed in the area below the laser cutting head 3 in the equipment body 1, the lens fixing mechanism 2 comprises a lens support 21 and an adsorption and fixing component 20, wherein the lens support 21 is fixed inside the equipment body 1, and a total of a plurality of adsorption and fixing components 20 are provided, which are installed on the lens support 21 in a distributed array, and a plurality of adsorption and fixing components 20 can perform distributed multi-point fixation on the bottom of the headlight lens, and the adsorption and fixing component 20 has a first state and a second state under external constraints, the first state is an adjustment state in which the adsorption and fixing component 20 can be lifted and lowered, and the second state is a locked state in which the adsorption and fixing component 20 is fixed, and the adsorption and fixing component 20 can be controlled to change from the first form to the second form, and a cutting material recovery port 211 is provided on the lens support 21, so that the cutting waste can enter the collection tank at the lower part of the equipment body 1 through the cutting material recovery port 211 (not shown in the figure).

[0020] Working principle: When the equipment is actually used, the headlight lens to be cut is first placed above the lens support 21 and fixed by the lens fixing mechanism 2, and then the headlight lens is cut by controlling the laser cutting head 3. The lens fixing mechanism 2 for fixing the headlight lens in the cutting equipment is mainly composed of a plurality of adsorption and fixing components 20 that can adsorb the bottom surface of the headlight lens, and each adsorption and fixing component 20 is relatively independent. The height of each adsorption and fixing component 20 can be independently adjusted according to the fixing requirements of the headlight lens so that it can adapt to the shape and structure of the headlight lens. In this way, during the cutting process of the headlight lens, the force on the entire headlight lens is more stable, thereby ensuring the cutting quality. Moreover, the setting of this distributed controllable fixing structure enables the cutting equipment to adjust the position of each adsorption and fixing component 20 according to the actual headlight lens model. Therefore, the cutting equipment can be suitable for cutting different headlight lenses and has a wider range of applications.

[0021] Specifically, Figure 4 - Figure 8As shown, in order to achieve the fixation of the headlight lens, in this embodiment, the adsorption and fixing component 20 includes a support column 202 with an air suction duct inside, a suction cup 201 for adsorbing the headlight lens is provided on the top of the support column 202, and an air suction pipe joint 204 that can be connected to an external negative pressure suction device is provided at the bottom of the support column 202, and an electromagnetic control valve 205 that can control the on-off of the air suction duct in the support column 202 is installed on the air suction pipe joint 204. When in use, the air suction pipe joint 204 is first connected to the external negative pressure suction device (such as a negative pressure pump) through an air pipe. After the headlight lens is placed, the electromagnetic control valve 205 at the bottom of the support column 202 that contacts the bottom of the headlight lens is opened to connect the internal air duct, and then the suction cup 201 is sucked by the negative pressure suction device to form a negative pressure inside it to fix the bottom of the headlight lens.

[0022] Specifically, Figure 4 - Figure 8 As shown, in order to achieve the free adjustment of the height of the adsorption and fixing component 20, in this embodiment, a clamping assembly 23 is installed at the position of each support column 202 below the lens support 21. The support column 202 is locked and unlocked by clamping and releasing the clamping assembly 23. When the clamping assembly 23 clamps and fixes the support column 202, the adsorption and fixing component 20 is in the second locked state. When the clamping assembly 23 releases the support column 202, the adsorption and fixing component 20 is in the first movable state.

[0023] Furthermore, if Fig. 9 - Fig.10 As shown, in this embodiment, the clamping assembly 23 includes a ring body 230, a movable clamp body 231 and a push control member 234, wherein the ring body 230 is fixed below the lens support 21 and is sleeved on the outside of the support column 202, an assembly cavity 2300 is provided inside the ring body 230, and the assembly cavity 2300 is communicated with the inner side of the ring body 230, the movable clamp body 231 is movably installed in the assembly cavity 2300, and is connected to the inner wall of the assembly cavity 2300 through a spring 233, The push control member 234 is installed in the assembly cavity 2300, and is used to control the movement of the movable clamp body 231 to achieve clamping and releasing of the support column 202. When the spring 233 is in a natural state, the movable clamp body 231 is completely accommodated in the assembly cavity 2300. When the push control member 234 pushes the movable clamp body 231 to gradually move outward, the spring 233 is gradually stretched, and the movable clamp body 231 can gradually clamp the support column 202 when moving outward.

[0024] Specifically, Fig. 9 - Fig.10As shown, in order to realize the control of the movable clamping body 231 by the push control member 234, in this embodiment, the push control member 234 is located below one side of the movable clamping body 231, and a wedge-shaped surface B2341 is provided on the side in contact with the movable clamping body 231; A wedge surface A2311 is provided below the side where the movable clamp body 231 contacts the push control member 234, wherein the wedge surface A2311 is matched with the wedge surface B2341, so that the push control member 234 can push the movable clamp body 231 to move radially toward the center of the ring body 230 along the assembly cavity 2300 when moving upward, thereby clamping the support column 202. When the push control member 234 moves downward, under the elastic pulling action of the spring 233, the movable clamp body 231 moves radially inside the assembly cavity 2300 along the assembly cavity 2300, thereby relaxing the support column 202.

[0025] Specifically, Fig.10 As shown, in order to ensure that the movable clamp body 231 does not separate from the assembly cavity 2300 when moving, in this embodiment, a limit groove 2310 is provided on the side of the movable clamp body 231 in the horizontal direction, and a limit block 2312 is provided on the inner wall of the assembly cavity 2300 at the position of the limit groove 2310. The limit block 2312 is engaged in the limit groove 2310 and can slide in the limit groove 2310, so as to ensure that the movable clamp body 231 does not fall off when moving. Specifically, in order to ensure the resetting effect of the spring 233, a plurality of springs 233 are provided, and the plurality of springs 233 are distributed in a rectangular array. In order to prevent the spring 233 from blocking the movement of the push control member 234, a makeshift groove 2342 capable of accommodating the spring 233 is provided at the bottom of the push control member 234.

[0026] Specifically, Fig. 9 As shown, in order to ensure the clamping effect of the movable clamp 231 on the support column 202, in this embodiment, a friction pad 232 is embedded and installed on the side of the movable clamp 231 that contacts the support column 202. The friction pad 232 is elastic. Therefore, when the movable clamp 231 clamps and fixes the support column 202, the friction force between the movable clamp 231 and the support column 202 is greater, so that the fixation of the support column 202 is more stable, and the setting of the friction pad 232 can still generate a certain extrusion friction force on the support column 202 when the movable clamp 231 is relaxed. The extrusion friction force can enable the support column 202 to overcome its own gravity and maintain a suspended state, avoiding the situation where the support column 202 directly falls to the lowest point after the movable clamp 231 is relaxed. On the one hand, it avoids the damage problem caused by the falling of the device structure, and on the other hand, it is convenient to adjust the position of the support column 202 later. Specifically, in order to prevent the support column 202 from rotating during use, which would cause the pipeline below to be scattered and blocked, the outer wall of the support column 202 is provided with at least one anti-rotation edge plate 203, and the hole on the lens support platform 21 for inserting the support column 202 is provided with a groove adapted to the anti-rotation edge plate 203.

[0027] Specifically, Figure 4 - Fig.10 As shown, in order to realize the control of the push control members 234 in all the adsorption fixing components 20 at one time, thereby ensuring the fixation stability of all the adsorption fixing components 20 in use, in this embodiment, a frame plate 22 is provided below the lens support 21, and a plurality of locking cylinders 210 for controlling the lifting of the frame plate 22 are installed on the lens support 21; A cross control piece 24 is provided at the corresponding position of each adsorption and fixing component 20, and the cross control piece 24 is sleeved on the outside of the support column 202 in the corresponding adsorption and fixing component 20. A locking push rod 242 that can extend and insert into the assembly cavity 2300 is provided on the top of the cross control piece 24. Two adjacent cross control pieces 24 are connected to each other, and the cross control piece 24 located at the outermost position is connected to the frame plate 22. Such a structural setting enables all the cross control pieces 24 to form a whole. When the locking cylinder 210 controls the frame plate 22 to rise, all the cross control pieces 24 rise uniformly, and the locking push rod 242 pushes the push control piece 234 to move upward, so that the movable clamp 231 can clamp the support column 202. When the frame plate 22 is controlled to move downward, all the cross control pieces 24 descend uniformly. Under the elastic pulling action of the spring 233, the movable clamp 231 gradually returns to its original position, so as to relax the support column 202.

[0028] Specifically, in order to allow the adsorption and fixing component 20 to be independently replaced when damaged and reduce maintenance costs, in this embodiment, the cross control member 24 is installed in a detachable manner, and the four ends of the cross control member 24 are grouped in pairs, respectively adopting a combined sub-end 240 and a combined female end 241 that can cooperate with each other, wherein the combined sub-end 240 and the combined female end 241 can be plugged into each other and fixedly connected by a pin, and the inner side of the frame plate 22 is also provided with a groove that can correspond to the combined sub-end 240 and the combined female end 241, and a pin rod for locking it is inserted from the outside of the frame plate 22.

[0029] Embodiment 2, this embodiment provides a technical solution: Figure 1 - Figure 3As shown, in order to realize the three-dimensional position control of the laser cutting head 3, in this embodiment, a three-dimensional control mechanism 4 for controlling the three-dimensional spatial movement of the laser cutting head 3 is installed inside the equipment body 1, and the three-dimensional control mechanism 4 includes an X-axis control component 40, a Y-axis control component 41 and a Z-axis control component 42, wherein the Y-axis control component 41 is installed above both sides inside the equipment body 1, and both ends of the X-axis control component 40 are slidably installed above the Y-axis control component 41, and the Z-axis control component 42 is movably installed on the X-axis control component 40, and the laser cutting head 3 is installed on the Z-axis control component 42. Therefore, through the cooperation of the X-axis control component 40, the Y-axis control component 41 and the Z-axis control component 42, the position control of the laser cutting head 3 in three-dimensional control is realized.

[0030] Specifically, Figure 1 - Figure 3 As shown, in this embodiment, the Y-axis control assembly 41 includes a Y-axis slide rail 410, a Y-axis slide table 411 slidably mounted on the Y-axis slide rail 410, a Y-axis toothed belt 412 for controlling the Y-axis slide table 411 to slide on the Y-axis slide rail 410, and a Y-axis drive motor 413 installed in the device body 1 for controlling the transmission of the Y-axis toothed belt 412; The X-axis control assembly 40 includes an X-axis slide rail 400 fixed at both ends on a Y-axis slide 411, an X-axis slide 401 slidably mounted on the X-axis slide rail 400, an X-axis toothed belt 402 for controlling the X-axis slide 401 to slide on the X-axis slide rail 400, and an X-axis drive motor 403 for controlling the transmission of the X-axis toothed belt 402; The Z-axis control assembly 42 includes a Z-axis rail column 421 fixed on the X-axis slide 401, a Z-axis slide 422 slidably mounted on the Z-axis rail column 421, and a Z-axis electric push rod 420 fixedly mounted above the Z-axis rail column 421. The piston rod of the Z-axis electric push rod 420 is connected to the top of the Z-axis slide 422. The laser cutting head 3 is fixedly mounted on the Z-axis slide 422. When in use, the Y-axis drive motor 413 drives the Y-axis slide 411 to move on the Y-axis slide rail 410 through the Y-axis toothed belt 412, so that the laser cutting head 3 is fixedly mounted on the Z-axis slide 422. The X-axis slide 400 and the X-axis slide table 401 in the X-axis control component 40 move along the Y-axis direction, and the X-axis drive motor 403 drives the X-axis slide table 401 to move on the X-axis slide 400 through the X-axis toothed belt 402, so that the Z-axis control component 42 moves as a whole along the X-axis direction. Finally, the Z-axis electric push rod 420 pushes the Z-axis slide 422 to move in the vertical direction of the Z-axis track column 421, so that the laser cutting head 3 installed on the Z-axis slide 422 moves synchronously, thereby realizing the three-dimensional position control of the laser cutting head 3.
