[0007] Furthermore, the driving assembly includes a slider disposed at the bottom end of the limiting plate, the operating plate is provided with a groove that cooperates with the slider, and the mounting groove is provided with a bidirectional hydraulic rod that drives the two sets of sliders to move relative to each other.

[0008] Furthermore, the locking mechanism includes an electric push rod mounted on a bracket, the output end of which is connected to a mounting plate, and the mounting plate is provided with a rolling assembly that cooperates with the drive mechanism.

[0009] Furthermore, the rolling assembly includes multiple sets of horizontal grooves formed on the mounting plate, with rollers rotatably disposed within the horizontal grooves, and heating rings built into the rollers.

[0010] Furthermore, the driving mechanism includes two sets of support rods disposed on the bottom of the inner wall of the mounting groove. The ends of the support rods are rotatably connected to rotating rods. The outer surface of the rotating rods is provided with rotating rollers. One set of the rotating rods has a driven gear sleeved on its outer surface. A meshing driving gear is provided on one side of the driven gear. A motor is provided on the operating table, and the output end of the motor is connected to the driving gear.

[0013] Furthermore, a collection box for collecting materials is provided below the unloading plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the laser cutting device for producing LED lamp profiles is reasonable and has the following advantages:

[0015] (1) The laser cutting device preheats the profile material by means of the rotating roller and roller with built-in heating ring, which has a significant process optimization effect. During the cutting process, the profile material is prone to thermal stress due to local high temperature change, which leads to deformation of the cutting surface or internal micro cracks. The device heats the rotating roller in the drive mechanism and the roller of the locking mechanism simultaneously. During the material conveying process, the profile material is heated evenly, and its overall temperature rises slowly. This preheating mechanism can significantly reduce the temperature difference between the material and the cutting area, thereby reducing thermal stress concentration. The temperature control of the heating ring makes the material reach the plastic softening state, so that the profile maintains good dimensional stability and surface quality after cutting, improves the product qualification rate and service life, and also avoids edge warping or cross-sectional cracks caused by cold cutting.

[0016] (2) The device integrates the pre-cutting process through the linkage design of the fixing mechanism and the air blowing dust removal. The automatic dust removal is achieved through the linkage of the sliding rod and the fixed sleeve. When the limiting plate clamps the profile through the bidirectional hydraulic rod, the mechanical movement of the sliding rod in the fixed sleeve will spray compressed air out of the jet pipe at high speed to form a directional airflow. The inclined jet pipe design can accurately blow away impurities in the area to be cut of the profile. The discharged airflow can remove the oxide layer, dust and cutting residue on the surface of the profile, and prevent impurities from melting and adhering during the cutting process, thereby reducing slag and pit defects. Moreover, the dust removal process is completely synchronized with the clamping action, without the need for additional operation steps, thus improving efficiency. Attached Figure Description

A sliding rod 402 is provided inside, and a connecting rod 403 is connected to the end of the sliding rod 402. The end of the connecting rod 403 away from the sliding rod 402 is connected to a limiting plate 404. A driving assembly is provided in the mounting groove 101 to drive the two limiting plates 404 to move relative to each other. A jet hose 407 communicating with the interior is provided at the end of the fixing sleeve 401 away from the sliding rod 402. An air inlet pipe 408 communicating with the interior is provided on one side of the fixing sleeve 401. A bracket 300 is provided on the operating plate 102. A locking mechanism cooperating with the fixing mechanism is installed on the bracket 300. A material unloading mechanism is provided on one side of the operating table 100.

[0028] The end of the jet hose 407 is designed to be inclined downwards, and a one-way exhaust valve is provided inside it. A one-way intake valve is provided inside the intake pipe 408.

[0029] The driving assembly includes a slider 405 disposed at the bottom of the limiting plate 404, a groove 406 that cooperates with the slider 405 on the operating plate 102, and a bidirectional hydraulic rod that drives the two sets of sliders 405 to move relative to each other in the mounting groove 101.

[0030] The locking mechanism includes an electric push rod 301 mounted on a bracket 300. The output end of the electric push rod 301 is connected to a mounting plate 302. The mounting plate 302 is provided with a rolling assembly that cooperates with the driving mechanism.

[0031] The rolling assembly includes multiple sets of horizontal grooves 303 formed on the mounting plate 302, and rollers 304 are rotatably arranged in the horizontal grooves 303, with heating rings built into the rollers 304.

[0032] The driving mechanism includes two sets of support rods 201 disposed on the bottom of the inner wall of the mounting groove 101. The ends of the support rods 201 are rotatably connected to rotating rods 200. Rotating rollers 202 are provided on the outer surface of the rotating rods 200. A driven gear 206 is sleeved on the outer surface of one set of the rotating rods 200. A drive gear 207 meshing with the driven gear 206 is provided on one side. A motor 208 is provided on the operating table 100, and the output end of the motor 208 is connected to the drive gear 207. A pulley 204 is provided on the rotating rods 200, and two sets of pulleys 204 are connected by a belt 205. A slot 203 that cooperates with the rotating rollers 202 is provided on the operating plate 102.

[0033] The unloading mechanism includes a groove 500 on the operating table 100, and an unloading plate 501 is rotatably disposed in the groove 500, and multiple holes are arrayed on the unloading plate 501.

[0034] The unloading plate 501 is provided with multiple sets of cams 502, and the cams 502 are provided with anti-slip texture.

[0035] A collection box 503 for collecting materials is provided below the unloading plate 501.

[0036] Working principle: In use, the profile material to be cut is placed on the operating table 100. The electric push rod 301 is activated, causing the mounting plate 302 to move downwards and press against the profile material. The motor 208 is activated, driving the drive gear 207 to rotate, which in turn drives the driven gear 206 meshing with it to rotate. The driven gear 206 drives the connected rotating rod 200 to rotate, causing the rotating roller 202 to rotate. Through the pulley 204 and belt 205, the rotating roller 202 on the opposite side is driven to rotate. When both sets of rotating rollers 202 rotate, they drive the profile material forward, coordinating with the rotating roller 302. 4. This design allows for better driving of the profile material towards the cutting equipment 103. The rotating roller 202 also has a heating ring inside, which, together with the heating ring inside the roller 304, preheats the profile material, raising its overall temperature and reducing thermal stress, thus preventing warping or cracking. When the profile material is conveyed forward, and its foremost end moves between the fixed mechanisms, the driving mechanism stops transmitting. At this time, the bidirectional hydraulic rod drives two sets of sliders 405 to move relative to each other, thereby causing the limiting plate 404 to move relative to each other, fixing both ends of the profile material. The locking mechanism further enhances stability and facilitates cutting. During the movement of the limiting plate 404… The sliding rod 402 is pushed forward within the fixed sleeve 401, causing it to compress the internal air and expel it through the air jet hose 407. This reduces dust or impurities on the surface of the profile material, preventing defects such as slag or pits from appearing on the cut surface and making the cutting process smoother. The air jet hose 407 can be adjusted as needed. After fixing, the cutting device 103 is started to cut the profile material. After cutting, the bidirectional hydraulic rod drives the two sets of limit plates 404 to move in opposite directions, thus releasing the restraints. At this time, the drive mechanism starts, and the rear plate continues to move forward, thus pushing the cut profile material forward. Because the unloading plate 501 is tilted, when the cut profile material is too close to the unloading plate 501, it falls onto the unloading plate 501 under the action of gravity. The cam 502 can make the cut profile material vibrate during the fall, so that the debris or impurities on it fall into the collection box 503 through the holes on the unloading plate 501 under the action of vibration. The anti-slip texture on the cam 502 can increase the friction, so that the cut profile material slides slowly. At this time, the uncut profile material behind it continues to be clamped. Since there will be flying debris during the cutting process, the flying debris will be blown away by the air jet hose 407 during the fixing process.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
