Description

Technical Field

[0001] The utility model relates to the technical field of blue light laser welding equipment, in particular to a blue light laser welding component. Background Art

[0002] Blue laser welding is a welding technology based on the characteristics of lasers. Its wavelength is about 450nm, which can achieve high-quality and uniform welding of non-ferrous metals such as copper and gold. Blue laser welding is fast, efficient and precise. In the existing technology, laser welding machines do not have the function of preventing smoke and dust. The smoke generated during the welding process has the potential risk of cancer and affects the health of workers. It also does not have the function of intercepting large particles of debris.

[0003] For example, the authorized patent document with application number 202122629469.X discloses a laser composite welding head, including a welding head body, an infrared laser interface, a blue laser interface and a laser outlet. The welding head body is provided with a first optical path and a second optical path. The infrared laser passes through the first optical path, and the blue laser passes through the second optical path and enters the first optical path. The infrared laser and the blue laser are coupled with a preset power ratio in the first optical path and are emitted from the laser outlet. The utility model couples the blue laser and the infrared laser and welds the high-reflective material, and adjusts the power ratio of the blue laser and the infrared laser so that the two work together to form a weld that is completely different from single-beam welding on the surface of the high-reflective material, thereby improving the process adaptability of welding high-reflective materials and meeting different welding strength requirements.

[0004] The above patent has the problem that the laser welding machine does not have the function of preventing smoke and dust. The smoke generated during the welding process has the potential of causing cancer and affects the health of workers. It also does not have the function of intercepting large particles of debris. Therefore, we need to provide a blue light laser welding component. Utility Model Content

The collection bucket is regularly disassembled from the connecting pipe to remove the intercepted debris, thereby better protecting the centrifugal fan and extending its service life. The smoke finally enters the adsorption part through the connecting box for filtration, and the smoke enters the sleeve and is adsorbed by the multi-layer activated carbon block to intercept most of the harmful gases. The multi-layer activated carbon block has three layers, which has a better purification effect on the smoke and avoids the lack of smoke and dust prevention function.

DETAILED DESCRIPTION

[0024] 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.

[0025] See also Figure 1-4 The utility model provides a technical solution: a blue light laser welding assembly, comprising:

[0026] A laser welding head 1, and a mounting plate 2 arranged on the back of the laser welding head 1;

[0027] A driver 3 is arranged at the bottom of the mounting plate 2;

[0028] A purification mechanism 4 is arranged on the top of the mounting plate 2 and is used for absorbing the smoke generated by the operation of the laser welding head 1;

[0029] The purification mechanism 4 includes a centrifugal fan 41, a curved pipe 42, an exhaust pipe 43, a connecting box 44, an adsorbent 45 and an intercepting member 46. The centrifugal fan 41 is fixedly installed on the top of the mounting plate 2, one side of the centrifugal fan 41 is connected to the curved pipe 42, the suction end of the curved pipe 42 is arranged on one side of the laser welding head 1, and an intercepting member 46 for intercepting debris is arranged inside the curved pipe 42. A connecting box 44 is arranged on one side of the centrifugal fan 41 through the pipe body, and one side of the connecting box 44 is passed through the exhaust pipe 43, and an adsorbent 45 is threadedly installed on the surface of the exhaust pipe 43.

[0030] The interception member 46 includes a collection barrel 461 and an external pipe 462. The bottom of the curved pipe 42 is connected to the external pipe 462. The collection barrel 461 is threadedly mounted on the surface of the external pipe 462. An interception net is arranged inside the curved pipe 42 at the external pipe 462.

[0031] In this embodiment, when the laser welding head 1 is working, smoke will be generated. When the centrifugal fan 41 is started, external air will enter the curved pipe 42, and the bottom of the curved pipe 42 is located on one side of the laser welding head 1, sucking the smoke into the curved pipe 42. The debris that mistakenly enters the curved pipe 42 will flow to the external pipe 462, and will be blocked by the interception part inside the external pipe 462, and may fall into the collection barrel 461. The collection barrel 461 is regularly disassembled from the connecting pipe to remove the intercepted debris, thereby better protecting the centrifugal fan 41 and extending its service life. The smoke passes through the connecting box 44 and finally enters the adsorption component 45 for filtration.

[0032] The adsorbent 45 includes a sleeve 451, a multi-layer activated carbon block 452 and a breathable net 453. The sleeve 451 is threadedly mounted on one side of the exhaust pipe 43. The multi-layer activated carbon block 452 is arranged inside the sleeve 451, and the breathable net 453 is embedded in one side of the sleeve 451.

[0033] Specifically, the flue gas enters the sleeve 451 and is adsorbed by the multi-layer activated carbon block 452, intercepting most of the harmful gases. The multi-layer activated carbon block 452 is three-layer, which has a better purification effect on the flue gas. The flue gas generated during the welding process contains various harmful substances, such as tiny smoke particles, harmful gases, etc. Activated carbon is a porous carbon material with a large specific surface area, so it can provide a large number of adsorption sites. When the welding fume passes through the activated carbon filter, the micropores and mesopores on the surface of the activated carbon will adsorb these harmful substances. Specifically, the adsorption of activated carbon is divided into two forms: physical adsorption and chemical adsorption. Physical adsorption refers to the adsorption of impurity molecules in the flue gas into the pores of the activated carbon through the intermolecular attraction on the surface of the activated carbon. Chemical adsorption uses the functional groups on the surface of the activated carbon to react chemically with the adsorbed substance to form a chemical bond, thereby further enhancing the adsorption effect, which can effectively prevent gas pollution, reduce the harm of harmful substances to the health of operators, and prevent the occurrence of occupational diseases.

[0034] The surface of the exhaust pipe 43 is integrally processed with a resistance ring 5, and one side of the resistance ring 5 is in contact with one side of the sleeve 451;

[0035] Furthermore, a resisting ring 5 is provided to be pressed and fitted against one side of the sleeve 451 to enhance the sealing performance.

[0036] In order to support the curved pipe 42 more firmly, a support frame 6 is further included, and the support frame 6 is installed between the mounting plate 2 and the curved pipe 42 .

[0037] An air collecting hood 7 is installed at the air inlet section at the bottom of the curved pipe 42, and a connecting plate 8 is installed between the curved pipe 42 and the laser welding head 1, and the connecting plate 8 is set as an anti-scalding plate;

[0038] It should be noted that the air collecting hood 7 is provided to increase the air intake surface of the curved pipe 42 , and the connecting plate 8 is provided to strengthen the curved pipe 42 .

[0039] In order to install the centrifugal fan 41 more firmly, the bottom of the centrifugal fan 41 is installed on the top of the installation plate 2 through a fixing seat 9.

[0040] When the laser welding head 1 of the device is working, smoke will be generated. When the centrifugal fan 41 is started, external air will enter the curved pipe 42, and the bottom of the curved pipe 42 is located on one side of the laser welding head 1, sucking the smoke into the curved pipe 42, and the debris that mistakenly enters the curved pipe 42 will flow to the external pipe 462, and be blocked by the interception part inside the external pipe 462, and may fall into the collection barrel 461. The collection barrel 461 is regularly disassembled from the connecting pipe to remove the intercepted debris, so as to better protect the centrifugal fan 41 and extend its service life. The smoke passes through the connecting box 44 and finally enters the adsorption part 45 for filtration. The smoke enters the sleeve 451 and is adsorbed by the multi-layer activated carbon block 452, intercepting most of the harmful gases. The multi-layer activated carbon block 452 has three layers, which has a better purification effect on the smoke.
