Description

Technical Field

[0002] The manufacturing stage of hardware products is the process of converting the design drawings in the research and development stage into actual products. This stage involves the selection of materials, the determination of processing technology, the optimization of production efficiency and the control of product quality. The manufacturing process needs to consider cost-effectiveness to ensure that the product can be produced at a reasonable cost while ensuring quality.

[0003] Laser welding, as a high-precision and high-efficiency modern welding technology, has been widely used in the field of industrial production. It uses a high-energy laser beam to irradiate the surface of the workpiece, melt the material through heat conduction and form a molten pool, thereby achieving the purpose of welding. In the process of hardware product development, laser welding can be used to weld it.

[0004] However, in the process of using laser welding equipment to weld hardware, the energy conversion efficiency of laser welding is relatively low. Most of the energy will be dissipated in the form of heat energy, and only a small part of the energy is used to melt and connect materials, resulting in energy waste and increased costs. In addition, the fume generated during welding will cause harm to the environment and operators. Summary of the invention

[0032] The laser welding mechanism 100 is started to perform laser welding on the workpiece, so that the heat recovery mechanism 200 is synchronously moved to the welding position of the workpiece, and the heat recovery mechanism 200 is located on both sides of the welding position of the workpiece so as to be closer to the welding position; When the laser welding mechanism 100 is started, most of the heat generated by the laser will diffuse outward, and the diffused heat will be absorbed by the heat recovery mechanism 200 to generate electricity and store the electricity.

A battery 209 is fixedly connected to the top of the front side of the electric telescopic rod 101, and the temperature difference power generation sheet 205 is electrically connected to the battery 209. Cleaning components 210 are fixedly connected to both sides of the laser welding head 103, and a collecting component 211 is fixedly connected to the bottom of the copper sheet 204.

[0035] The cleaning assembly 210 includes a connecting sleeve 210a, which is provided with two groups and three in each group. The inner side of the connecting sleeve 210a is fixedly connected to the two sides of the laser welding head 103. The inside of the connecting sleeve 210a is slidably connected with a movable rod 210b. The inner side of the movable rod 210b is fixedly connected with a second spring 210c. The other end of the second spring 210c is fixedly connected to the inner side of the inner wall of the connecting sleeve 210a. Scraping strips 210d are provided on both sides of the laser welding head 103. The inner side of the scraping strip 210d is fixedly connected to the outer side of the movable rod 210b.

[0036] The collecting assembly 211 includes a limiting support 211a, which is provided with two groups and each group has three members. The inner side of the top of the limiting support 211a is fixedly connected to the bottom of the copper sheet 204. The bottom of the copper sheet 204 is provided with a collecting box 211b. The interior of the collecting box 211b is slidably connected to the surface of the limiting support 211a. The top of the limiting support 211a is fixedly connected with a second tension spring 211c. The second tension spring 211c is sleeved on the surface of the limiting support 211a. The other end of the second tension spring 211c is connected to the collecting box 211b. The top of the outer side of the inner wall of the collecting box 11b is fixedly connected, the inner side of the collecting box 211b is fixedly connected with a first magnetic sheet 211d, the inner side of the first magnetic sheet 211d is provided with a second magnetic sheet 211e, the top of the second magnetic sheet 211e is fixedly connected to the two sides of the bottom of the laser welding head 103, the outer side of the second magnetic sheet 211e and the inner side of the first magnetic sheet 211d are of the same polarity and repel each other, the outer side of the top of the collecting box 211b is fixedly connected with an elastic blocking cloth 211f, and the top of the inner side of the elastic blocking cloth 211f is fixedly connected to the temperature difference power generation sheet 205 close to the collecting box 211b.

[0037] Specifically, when the transmission block 102 moves downward, it will drive the copper sheet 204 to move downward to both sides of the welding point of the workpiece. When the workpiece is welded, the laser emitted by the laser welding head 103 will diffuse most of the heat outward during the movement, and part of the heat that has been conducted to the welding point of the workpiece will also continue to diffuse part of the heat outward. At this time, the copper sheets 204 on both sides of the welding point of the workpiece will conduct this heat to the inner side of the thermoelectric power generation sheet 205, so that there is a large temperature difference between the temperature inside and outside of the thermoelectric power generation sheet 205, thereby causing the thermoelectric power generation sheet 205 to generate electricity. At this time, the thermoelectric power generation sheet 205 can boost the generated voltage through an external transformer to store it in the battery 209.

[0038] Specifically, when the copper sheet 204 moves, the scraper 210d is used to scrape off the particles on the inner side of the copper sheet 204 to avoid the situation where some particles in the smoke generated by welding the workpiece adhere to the inner side of the copper sheet 204, causing the copper sheet 204 to thicken and the presence of a medium between the copper sheet 204 and the heat, thereby reducing the thermal conductivity of the copper sheet 204. The stability of the thermal conductivity of the copper sheet 204 during use can be ensured, and when the copper sheet 204 does not move downward, the scraper 210d is pressed tightly, so that the copper sheet 204 is in an unfolded shape. After the copper sheet 204 moves downward, the bottom of the inner side of the copper sheet 204 will move inward and reset, so that the copper sheet 204 can be closer to the welding point of the workpiece, thereby conducting more heat, and making the temperature difference on both sides of the thermoelectric power generation sheet 205 larger.

[0039] Specifically, when the copper sheet 204 is moving downward or upward, the collecting box 211b will be below the copper sheet 204, so that the particles scraped off from the inner side of the copper sheet 204 will slide into the inside of the collecting box 211b, preventing the particles from falling directly and adhering to the surface of the workpiece and affecting the welding efficiency of the workpiece. When the copper sheet 204 is completely moved upward and retracted, the inner side of the first magnetic sheet 211d and the outer side of the second magnetic sheet 211e are repelled by the opposite poles, so that the magnetic repulsion force can be used to push the collecting box 211b to move outward and retract. At this time, the elastic blocking cloth 211f can be used to block the outer side of the top of the collecting box 211b, while the inner side of the top of the collecting box 211b is blocked by the copper sheet 204, thereby ensuring that the collecting box 211b is covered and closed, preventing the particles collected in the collecting box 211b from being blown out.

[0040] Furthermore, when the transmission block 102 moves downward, the transmission block 102 will also drive the movable sleeve 203 to move downward through the limit block 206, so that the movable sleeve 203 is separated from the magnetic block 202, and the movable sleeve 203 will be away from the magnetic field of the magnetic block 202. At this time, the tension of the first tension spring 208 and the deadweight of the movable sleeve 203 are utilized to make the movable sleeve 203 drive the copper sheet 204 to move downward, thereby ensuring that the transmission block 102 moves downward for a shorter distance, and also making the movable sleeve 203 drive the copper sheet 204 to move downward, and then the copper sheet 204 will be on both sides of the welding place of the workpiece, and in the process of the movable sleeve 203 moving downward, it will drive the limit block 206 to move along the inner limit groove 207 The laser welding head 103 moves along the path of the wall, thereby ensuring the stability of movement and avoiding deviation. When the workpiece is welded, the laser emitted by the laser welding head 103 will diffuse most of the heat outward during the movement, and part of the heat that has been conducted to the welding point of the workpiece will also continue to diffuse part of the heat outward. At this time, the copper sheets 204 on both sides of the welding point of the workpiece will conduct this heat to the inner side of the thermoelectric power generation sheet 205, so that there is a large temperature difference between the temperature inside and outside the thermoelectric power generation sheet 205, so that the thermoelectric power generation sheet 205 generates electricity. At this time, the thermoelectric power generation sheet 205 can boost the generated voltage through an external transformer to store it in the battery 209.

[0041] Furthermore, during the movement of the copper sheet 204, the elastic force of the second spring 210c inside the connecting sleeve 210a can be used to push the movable rod 210b to move inward, so that the movable rod 210b pushes the scraper 210d to fit the inner side of the copper sheet 204, thereby continuously scraping the inner side of the copper sheet 204 when the copper sheet 204 moves, thereby avoiding the situation in which when the workpiece is welded and the smoke is generated, some particles in the smoke adhere to the inner side of the copper sheet 204, causing the copper sheet 204 to become thicker and there is a medium between the heat and the copper sheet 204, thereby reducing the thermal conductivity of the copper sheet 204. In this case, the scraper 210d is used to scrape off the particles, which can ensure the stability of the heat conduction efficiency of the copper sheet 204 during use. When the copper sheet 204 does not move downward, the scraper 210d is pressed tightly, so that the copper sheet 204 is in an unfolded shape. When the copper sheet 204 moves downward, the bottom of the inner side of the copper sheet 204 lacks obstruction. At this time, the bottom of the inner side of the copper sheet 204 will move inward and reset, so that the copper sheet 204 can be closer to the welding point of the workpiece to conduct more heat, so that the temperature difference on both sides of the temperature difference power generation sheet 205 is greater.

[0042] Furthermore, when the scraper 210d scrapes off the particles attached to the inner side of the copper sheet 204, the copper sheet 204 is in the process of moving downward or upward. At this time, the inner side of the first magnetic sheet 211d does not correspond to the outer side of the second magnetic sheet 211e, so that the tension of the second tension spring 211c is released, and then the second tension spring 211c pulls the collection box 211b to move inward along the limiting support 211a, and then the collection box 211b is under the copper sheet 204, so that the particles scraped off the inner side of the copper sheet 204 will slide into the inside of the collection box 211b, so as to prevent the particles from falling directly and adhering to the surface of the workpiece and affecting the welding efficiency of the workpiece. When the sheet 204 is completely moved upward and retracted, the copper sheet 204 will drive the collection box 211b to be retracted upward synchronously. At this time, the collection box 211b will drive the first magnetic sheet 211d to approach the second magnetic sheet 211e, and then use the inner side of the first magnetic sheet 211d and the outer side of the second magnetic sheet 211e to repel each other, so that the magnetic repulsion force can be used to push the collection box 211b to move outward and retract. At this time, the elastic blocking cloth 211f can be used to block the outer side of the top of the collection box 211b, and the inner side of the top of the collection box 211b is blocked by the copper sheet 204, thereby ensuring that the collection box 211b is covered and closed, preventing the particles collected in the collection box 211b from being blown out.

[0043] It should be noted that the surface of the thermoelectric power generation sheet 205 is coated with a waterproof coating, which can prevent the thermoelectric power generation sheet 205 from being short-circuited and damaged when it comes into contact with airflow carrying a large amount of moisture.

[0044] Reference Figures 1 to 5 , which is the third embodiment of the present invention, provides a fume treatment mechanism 300, through which the fume during welding can be treated.

The surface of the pressing pump 304d-2 is sleeved with a piston block 304d-9, and the piston block 304d-9 is located on the top of the first spring 304d-6.

[0049] The bottom of the back of the transmission member 304d-5 and the left side of the front of the force-bearing member 304d-4 are both inclined. The left side of the front of the force-bearing member 304d-4 is inlaid with a ball 304d-10. There are several balls 304d-10 and they are distributed at equal distances in a rectangular shape.

[0050] Specifically, during the welding process of the workpiece, the electric exhaust fan 303 draws air from the inside of the fume treatment box 301 and uses the activated carbon filter plate 302 to filter out the particles and harmful substances in the fume and then discharge the gas. The electricity used by the electric exhaust fan 303 can be generated by the battery 209 using the electricity generated by the temperature difference power generation sheet 205. If the battery 209 is low on power or damaged, an external power supply can be connected to power the electric exhaust fan 303, thereby saving energy.

[0051] Specifically, when the electric exhaust fan 303 discharges the filtered airflow to the outside, the airflow will be divided by the triangular bar 304c and blown evenly to the outside of the thermoelectric power generation sheet 205, so that the outside of the thermoelectric power generation sheet 205 is cooled by the airflow, making the temperature of the outside of the thermoelectric power generation sheet 205 lower. At this time, the temperature difference between the inside and outside of the thermoelectric power generation sheet 205 will be increased, so that the power generation of the thermoelectric power generation sheet 205 will be increased.

[0052] Specifically, the electric exhaust fan 303 continuously rotates, which continuously drives the transmission member 304d-5 to rotate. Whenever the transmission member 304d-5 rotates downward, it drives the top of the pressing pump 304d-2 to move downward, extracting part of the water stored in the water storage box 304d-1 and spraying it out in the form of mist through the atomizing nozzle 304d-3. The water mist is discharged outward under the action of the airflow, so that it is blown to the outside of the temperature difference power generation sheet 205, so that the temperature difference power generation sheet 205 is The dual effects of water mist and airflow on the outside of 05 improve the cooling effect on the outside of the thermoelectric power generation sheet 205, further improve the temperature difference between the inside and outside of the thermoelectric power generation sheet 205, thereby further improving the power generation of the thermoelectric power generation sheet 205. When the amount of water inside the water storage box 304d-1 is insufficient, the user can remove the sealing cover 304d-7 by twisting the sealing cover 304d-7 and add water to the inside of the water storage box 304d-1, thereby facilitating the addition of water to the water storage box 304d-1.

[0053] Specifically, when the pressing pump 304d-2 moves downward, it will synchronously drive the piston block 304d-9 to move downward to the inside of the reduction housing 304d-8. Due to the friction between the surface of the piston block 304d-9 and the inner wall surface of the reduction housing 304d-8, the top of the pressing pump 304d-2 slowly moves upward, so that the pressing pump 304d-2 can continue to spray water mist at short intervals, thereby avoiding excessive spraying of water mist, causing excessive moisture inside the gathering hood and the flue gas treatment box 301 and condensing large water droplets, resulting in water reflux and excessive water consumption.

[0054] Specifically, when the transmission member 304d-5 collides with the force-bearing member 304d-4, the bottom of the back side of the transmission member 304d-5 and the left side of the front side of the force-bearing member 304d-4 are inclined, so that the collision force of the transmission member 304d-5 on the force-bearing member 304d-4 is guided to a certain extent, ensuring that the force-bearing member 304d-4 can move downward, and then by setting the ball 304d-10, the friction force generated during transmission between the transmission member 304d-5 and the force-bearing member 304d-4 can be greatly reduced, thereby avoiding excessive friction that increases the degree of loss of the transmission member 304d-5 and the force-bearing member 304d-4.

[0055] Furthermore, during the welding process of the workpiece, the electric exhaust fan 303 is turned on, so that the electric exhaust fan 303 draws the air inside the fume treatment box 301 and discharges it to the outside. At this time, under the action of the airflow, the fume generated during the welding of the workpiece and continuously diffused to the outside will be drawn into the inner wall of the fume treatment box 301 and discharged to the outside through the activated carbon filter plate 302. At this time, the activated carbon filter plate 302 can filter the particles and harmful substances in the fume, so that the gas can be discharged to the standard. The electricity used by the electric exhaust fan 303 can be generated by the battery 209 using the temperature difference power generation sheet 205. If the battery 209 is insufficient or damaged, an external power supply can be connected to power the electric exhaust fan 303, thereby saving energy.

[0056] Furthermore, when the electric exhaust fan 303 discharges the filtered airflow to the outside, the discharged airflow will be gathered by the air collecting hood 304a, and then flow through the air guide pipe 304b and arranged to the outside of the triangular bar 304c. Then the airflow is divided by the triangular bar 304c and evenly blown to the outside of the thermoelectric power generation sheet 205, so that the outside of the thermoelectric power generation sheet 205 is cooled by the airflow, making the temperature of the outside of the thermoelectric power generation sheet 205 lower. At this time, the temperature difference between the inside and outside of the thermoelectric power generation sheet 205 will be increased, so that the power generation of the thermoelectric power generation sheet 205 will be increased.

[0057] Furthermore, as the electric exhaust fan 303 continuously rotates, the transmission member 304d-5 is continuously driven to rotate. Whenever the transmission member 304d-5 rotates to the bottom, it will strike the force-bearing member 304d-4, causing the force-bearing member 304d-4 to move downward, and then the force-bearing member 304d-4 will drive the top of the pressing pump 304d-2 to move downward. At this time, the pressing pump 304d-2 will be squeezed to extract part of the water stored in the water storage box 304d-1 and spray it out in the form of mist through the atomizing nozzle 304d-3, and the water mist is discharged outward under the action of the airflow, so that it is blown to the outside of the temperature difference power generation sheet 205, so that the outside of the temperature difference power generation sheet 205 is between the water mist and The dual action of the airflow improves the cooling effect on the outside of the thermoelectric power generation sheet 205, further improves the temperature difference between the inside and outside of the thermoelectric power generation sheet 205, thereby further improving the power generation of the thermoelectric power generation sheet 205. When the transmission member 304d-5 and the force-bearing member 304d-4 are separated, the elastic force of the first spring 304d-6 will be released, thereby pushing the top of the pressing pump 304d-2 to move upward and reset, thereby preparing for the next use. In this way, when the amount of water in the water storage box 304d-1 is insufficient, the user can remove the sealing cover 304d-7 by twisting the sealing cover 304d-7 and add water to the inside of the water storage box 304d-1, thereby facilitating the addition of water to the water storage box 304d-1.

[0058] Furthermore, when the pressing pump 304d-2 moves downward, it will synchronously drive the piston block 304d-9 to move downward, so that the piston block 304d-9 enters the interior of the reduction housing 304d-8. At this time, when the elastic force of the first spring 304d-6 is used to push the top of the pressing pump 304d-2 to move upward and reset, the pressing pump 304d-2 will drive the piston block 304d-9 to move upward synchronously. At this time, due to the friction between the surface of the piston block 304d-9 and the inner wall surface of the reduction housing 304d-8, the pressing pump 304d-2 is pushed upward and reset. The top of d-2 moves slowly upward. When the piston block 304d-9 is separated from the deceleration housing 304d-8, the elastic force of the first spring 304d-6 will directly drive the top of the pressing pump 304d-2 to move upward quickly, thereby moving the force-bearing member 304d-4 to the collision point, so that the pressing pump 304d-2 can continue to spray water mist at short intervals, avoiding excessive spraying of water mist, causing excessive moisture inside the gathering hood and the flue gas treatment box 301 and condensing large water droplets, resulting in water reflux and excessive water consumption.

[0059] Furthermore, when the transmission member 304d-5 collides with the force-bearing member 304d-4, the bottom of the back side of the transmission member 304d-5 and the left side of the front side of the force-bearing member 304d-4 are both inclined, so that the collision force of the transmission member 304d-5 on the force-bearing member 304d-4 is guided to a certain extent, ensuring that the force-bearing member 304d-4 can move downward, and then by setting the ball 304d-10, the friction force generated during transmission between the transmission member 304d-5 and the force-bearing member 304d-4 can be greatly reduced, thereby avoiding excessive friction that increases the degree of wear of the transmission member 304d-5 and the force-bearing member 304d-4.

[0060] The remaining structure is the same as that of Example 2.

[0061] Reference Figures 1 to 5 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: this embodiment provides a laser welding device for hardware processing.

[0062] When welding of the workpiece is required, the electric telescopic rod 101 is started to drive the transmission block 102 to move downward, so that the transmission block 102 drives the laser welding head 103 to move downward and close to the position of the workpiece, and then the laser welding head 103 can be turned on and generate laser to weld the workpiece.

[0063] When the transmission block 102 moves downward, the transmission block 102 will also drive the movable sleeve 203 to move downward through the limit block 206, so that the movable sleeve 203 is separated from the magnetic block 202, and the movable sleeve 203 will be away from the magnetic field of the magnetic block 202. At this time, the tension of the first tension spring 208 and the deadweight of the movable sleeve 203 are used to make the movable sleeve 203 drive the copper sheet 204 to move downward, thereby ensuring that the transmission block 102 moves downward The distance is short and the movable sleeve 203 can also drive the copper sheet 204 to move downward. Subsequently, the copper sheet 204 will be on both sides of the welding position of the workpiece. In the process of the movable sleeve 203 moving downward, it will drive the limit block 206 along the path of the inner wall of the limit groove 207 The laser welding head 103 moves along the same path, thereby ensuring the stability of movement and avoiding deviation. When the workpiece is welded, the laser emitted by the laser welding head 103 will diffuse most of the heat outward during the movement, and part of the heat that has been conducted to the welding point of the workpiece will also continue to diffuse part of the heat outward. At this time, the copper sheets 204 on both sides of the welding point of the workpiece will conduct this heat to the inner side of the thermoelectric power generation sheet 205, so that there is a large temperature difference between the temperature inside and outside the thermoelectric power generation sheet 205, thereby causing the thermoelectric power generation sheet 205 to generate electricity. At this time, the thermoelectric power generation sheet 205 can boost the generated voltage through an external transformer to store it in the battery 209.

[0064] During the movement of the copper sheet 204, the elastic force of the second spring 210c inside the connecting sleeve 210a can push the movable rod 210b to move inward, so that the movable rod 210b pushes the scraper strip 210d to fit the inner side of the copper sheet 204, thereby continuously scraping the inner side of the copper sheet 204 when the copper sheet 204 moves, thereby preventing the particles in the smoke from adhering to the inner side of the copper sheet 204 when the workpiece is welded, causing the copper sheet 204 to become thicker and the medium between the copper sheet 204 and the heat to reduce the thermal conductivity of the copper sheet 204. Scraping off the particles with the scraper 210d can ensure the stability of the heat conduction efficiency of the copper sheet 204 during use, and when the copper sheet 204 does not move downward, the scraper 210d is pressed tightly, so that the copper sheet 204 is in an unfolded shape. When the copper sheet 204 moves downward, the bottom of the inner side of the copper sheet 204 lacks obstruction. At this time, the bottom of the inner side of the copper sheet 204 will move inward and reset, so that the copper sheet 204 can be closer to the welding point of the workpiece to conduct more heat, making the temperature difference on both sides of the thermoelectric power generation sheet 205 larger.

[0065] When the scraper strip 210d scrapes off the particles attached to the inner side of the copper sheet 204, the copper sheet 204 is in the process of moving downward or upward. At this time, the inner side of the first magnetic sheet 211d does not correspond to the outer side of the second magnetic sheet 211e, so that the tension of the second tension spring 211c is released, and then the second tension spring 211c pulls the collection box 211b to move inward along the limiting support 211a, and then the collection box 211b is under the copper sheet 204, so that the particles scraped off the inner side of the copper sheet 204 will slide into the inside of the collection box 211b, so as to prevent the particles from falling directly and adhering to the surface of the workpiece and affecting the welding efficiency of the workpiece. When 04 moves completely upward and retracts, the copper sheet 204 will drive the collecting box 211b to retract upward synchronously. At this time, the collecting box 211b will drive the first magnetic sheet 211d to approach the second magnetic sheet 211e, and then use the inner side of the first magnetic sheet 211d and the outer side of the second magnetic sheet 211e to repel each other, so as to use the magnetic repulsion force to push the collecting box 211b to move outward and retract. At this time, the elastic blocking cloth 211f can be used to block the outer side of the top of the collecting box 211b, and the inner side of the top of the collecting box 211b is blocked by the copper sheet 204, so as to ensure that the collecting box 211b is covered and closed, and the particles collected in the collecting box 211b are prevented from being blown out.

[0066] During the welding process of the workpiece, the electric exhaust fan 303 is turned on, so that the electric exhaust fan 303 draws the air inside the fume treatment box 301 and discharges it to the outside. At this time, under the action of the airflow, the fume generated during the welding of the workpiece and continuously diffused to the outside will be drawn into the inner wall of the fume treatment box 301 and discharged to the outside through the activated carbon filter plate 302. At this time, the activated carbon filter plate 302 can filter the particles and harmful substances in the fume, so that the gas can be discharged to the standard. The electricity used by the electric exhaust fan 303 can be generated by the battery 209 using the temperature difference power generation sheet 205. If the battery 209 is insufficient or damaged, an external power supply can be connected to power the electric exhaust fan 303, thereby saving energy.

[0067] When the electric exhaust fan 303 discharges the filtered airflow to the outside, the discharged airflow will be gathered by the air gathering hood 304a, and then flow through the air guide pipe 304b and arranged to the outside of the triangular bar 304c. Then the airflow is divided by the triangular bar 304c and evenly blown to the outside of the thermoelectric power generation sheet 205, so that the outside of the thermoelectric power generation sheet 205 is cooled by the airflow, making the temperature of the outside of the thermoelectric power generation sheet 205 lower. At this time, the temperature difference between the inside and outside of the thermoelectric power generation sheet 205 will be increased, so that the power generation of the thermoelectric power generation sheet 205 will be increased.

[0068] As the electric exhaust fan 303 continuously rotates, the transmission member 304d-5 is continuously driven to rotate. Whenever the transmission member 304d-5 rotates to the bottom, it will strike the force-bearing member 304d-4, causing the force-bearing member 304d-4 to move downward. Then the force-bearing member 304d-4 will drive the top of the pressing pump 304d-2 to move downward. At this time, the pressing pump 304d-2 will be squeezed to extract part of the water stored in the water storage box 304d-1 and spray it out in the form of mist through the atomizing nozzle 304d-3. The water mist is discharged outward under the action of the airflow, so that it is blown to the outside of the temperature difference power generation sheet 205, so that the outside of the temperature difference power generation sheet 205 is affected by the water mist and the airflow. The dual effects improve the cooling effect on the outside of the thermoelectric power generation sheet 205, further improve the temperature difference between the inside and outside of the thermoelectric power generation sheet 205, thereby further improving the power generation of the thermoelectric power generation sheet 205. When the transmission member 304d-5 and the force-bearing member 304d-4 are separated, the elastic force of the first spring 304d-6 will be released, thereby pushing the top of the pressing pump 304d-2 to move upward and reset, so as to prepare for the next use. In this way, when the water level in the water storage box 304d-1 is insufficient, the user can remove the sealing cover 304d-7 by twisting the sealing cover 304d-7 and add water to the inside of the water storage box 304d-1, thereby facilitating the addition of water to the water storage box 304d-1.

[0069] When the pressing pump 304d-2 moves downward, it will synchronously drive the piston block 304d-9 to move downward, so that the piston block 304d-9 enters the interior of the reduction housing 304d-8. At this time, when the elastic force of the first spring 304d-6 is used to push the top of the pressing pump 304d-2 to move upward and reset, the pressing pump 304d-2 will drive the piston block 304d-9 to move upward synchronously. At this time, due to the friction between the surface of the piston block 304d-9 and the inner wall surface of the reduction housing 304d-8, the pressing pump 304d- 2 moves slowly upward. When the piston block 304d-9 is separated from the deceleration housing 304d-8, the elastic force of the first spring 304d-6 will directly drive the top of the pressing pump 304d-2 to move upward quickly, thereby moving the force-bearing member 304d-4 to the collision point, so that the pressing pump 304d-2 can continue to spray water mist at short intervals, thereby avoiding excessive spraying of water mist, causing excessive moisture inside the gathering hood and the flue gas treatment box 301 and condensing large water droplets, resulting in water reflux and excessive water consumption.

[0070] When the transmission member 304d-5 collides with the force-bearing member 304d-4, the bottom of the back side of the transmission member 304d-5 and the left side of the front side of the force-bearing member 304d-4 are arranged at an angle, so that the collision force of the transmission member 304d-5 on the force-bearing member 304d-4 is guided to a certain extent, ensuring that the force-bearing member 304d-4 can move downward, and the ball 304d-10 is arranged to greatly reduce the friction force generated during transmission between the transmission member 304d-5 and the force-bearing member 304d-4, thereby avoiding excessive friction that increases the degree of wear of the transmission member 304d-5 and the force-bearing member 304d-4.

[0071] In summary, when the laser welding mechanism 100 is started to perform laser welding on the workpiece, the heat recovery mechanism 200 will be started to generate electricity from the diffused heat to avoid a large amount of heat waste. At the same time, the smoke treatment mechanism 300 will be started to treat the welding smoke to prevent the smoke from directly diffusing into the air and affecting the working environment and the air environment. In addition, the smoke treatment mechanism 300 can be powered by the electricity generated by the heat recovery mechanism 200, thereby saving energy.
