[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: a laser welding device for producing optical devices, including a body 1, a motor 3 is installed at the inner bottom of the body 1, a threaded rod 4 is fixedly connected to the output end of the motor 3, a threaded block 5 is threadedly connected to the outer surface of the threaded rod 4, and connecting rods 6 are rotatably connected to the left and right sides of the outer side of the threaded block 5, a processing table 9 is fixedly connected to the inside of the body 1, and limiting grooves 8 are provided on the left and right sides of the inner side of the processing table 9, a guide rod 11 is fixedly connected to the inner side of the limiting groove 8, a slider 7 is slidably connected to the outer side of the guide rod 11, and a moving block 10 is fixedly connected to the top of the slider 7, and a smoke removal component is arranged on the top of the body 1, the other end of the connecting rod 6 is rotatably connected to the bottom of the slider 7 on the adjacent side, and the outer side of the slider 7 is slidably connected to the inner wall of the limiting groove 8.

[0024] Specifically, installing the motor 3 on the inner bottom of the body 1 can keep it stable during operation, and then the operation of the motor 3 can drive the threaded rod 4 to rotate, and the rotation of the threaded rod 4 will cause the threaded block 5 to move, and the threaded block 5 can drive one end of the two connecting rods 6 to move, and then the other end of the connecting rod 6 can drive the slider 7 to slide along the guide rod 11, wherein the guide rod 11 guides the slider 7 and can maintain horizontal movement under the restriction of the limit groove 8, so that the slider 7 drives the two moving blocks 10 to approach each other, and the moving block 10 can push the telescopic rod 12 to move, so that the two clamping blocks 20 are close to each other, thereby clamping and fixing the optical device to avoid movement during welding and ensure the accuracy of welding.

[0025] Reference Figure 2A protective door 2 is rotatably connected to the upper front side of the machine body 1, and the smoke removal assembly includes a smoke removal box 14, which is fixedly connected to the top of the machine body 1, an exhaust fan 15 is fixedly connected to the left side of the outside of the smoke removal box 14, a smoking pipe 16 is fixedly connected to the right side of the outside of the smoke removal box 14, a smoke collecting hood 17 is fixedly connected to the inner top of the machine body 1, and the top of the smoke collecting hood 17 is fixedly connected to the other end of the smoking pipe 16.

[0026] Specifically, by generating an airflow when the exhaust fan 15 is in operation, the smoke generated during welding can be collected by the smoke collecting hood 17, and then transported to the smoke removal box 14 through the smoking pipe 16. After being processed inside the smoke removal box 14, the toxic gases and fine particles in the smoke can be absorbed, and with the cooperation of the protective door 2, the diffusion of the smoke can be reduced, preventing toxic gases from diffusing into the air to pollute the environment and affect the health of the operators. At the same time, a transparent observation window is installed on the protective door 2 to facilitate the staff to observe the welding process.

[0027] Reference Figure 4 The adjacent sides of the two moving blocks 10 are fixedly connected with a telescopic rod 12, and the other end of the telescopic rod 12 is fixedly connected with a clamping block 20. A spring 21 is sleeved on the outside of the telescopic rod 12, and one end of the spring 21 is fixedly connected to the outside of the moving block 10, and the other end of the spring 21 is fixedly connected to the outside of the clamping block 20.

[0028] Specifically, the elastic effect of the spring 21 can prevent damage to the optical device caused by excessive clamping force. At the same time, there is no need to frequently adjust the position of the moving block 10, and optical devices of different sizes can be clamped, thereby improving the flexibility of use of the equipment. The telescopic rod 12 can ensure that the spring 21 can be stably contracted, thereby improving the stability of the structure operation.

[0029] Reference Figure 3 A laser welding mechanism 13 is provided on the inner top of the machine body 1 , an activated carbon plate 18 is installed on the inner left side of the smoke removal box 14 , and a filter plate 19 is installed on the inner right side of the smoke removal box 14 .

[0030] Specifically, precise welding of optical devices is achieved through the laser welding mechanism 13, which improves the welding quality. The smoke is filtered and absorbed by the filter plate 19 and the activated carbon plate 18 respectively, which reduces the emission of impurities and harmful gases in the smoke and reduces pollution to the environment.

[0031] Working principle: When using this equipment, the optical device can be placed above the processing table 9, and the motor 3 can be started to drive the threaded rod 4 to rotate, which will cause the threaded block 5 to move. The threaded block 5 drives the connecting rods 6 connected on both sides to move, and then the other end drives the slider 7 to slide along the guide rod 11, and can maintain horizontal movement under the restriction of the limit groove 8, so that the slider 7 drives the two moving blocks 10 to approach each other, and the moving block 10 can push the telescopic rod 12 to move, so that the two clamping blocks 20 are close to each other, so that the optical device is clamped and fixed to avoid movement during welding and ensure the accuracy of welding. At the same time, the elastic action of the spring 21 can ensure that the optical device is not damaged during clamping, and optical devices of different sizes can be clamped without frequently adjusting the position of the moving block 10, thereby improving the flexibility of the equipment. When welding is being performed, the exhaust fan 15 can be started to generate airflow when the exhaust fan 15 is running, and then the smoke generated by welding is absorbed by the smoke collecting hood 17, and transported to the smoke removal box 14 through the smoking pipe 16, and the smoke is processed by the filter plate 19 and the activated carbon plate 18 inside the smoke removal box 14, and the diffusion of smoke is reduced with the cooperation of the protective door 2, so as to prevent toxic gases from diffusing into the air to pollute the environment and affect the health of the operators.
