[0038] like Figure 3As shown, the surface of the first baffle 208 is provided with a first electrically controlled slide rail 104, and the end of the suspension arm 109 away from the welding machine 101 is slidably arranged inside the first electrically controlled slide rail 104, the upper surface of the second baffle 209 is connected to the bottom of the dust bin 110, the air supply pipe 107 passes through the first baffle 208 and is connected to the dust bin 110, the dust bin 110 is connected to the inside of the air extraction bin 112 through the pipe 111, an exhaust pipe is provided on the side of the air extraction bin 112 away from the pipe 111, and an electrically controlled air valve is provided inside the exhaust pipe close to the air extraction bin 112. During use, the electric control slide rail is used to provide a moving track for the suspension arm 109, so that it can move laterally along the surface of the electric control slide rail, so that the welding machine 101 located on the suspension arm 109 is moved to the top of the workpiece that requires the welding machine, so as to facilitate the welding of the workpiece. In addition, during the welding process, a driving motor 113 is arranged and cooperates with the air nozzle 106 through the air supply pipe 107 to suck the impurities and dust on the workpiece and the main body housing 201 into the dust storage bin 110, and discharge it to the outside through the exhaust pipe, so as to ensure that the workpiece will not contain impurities and dust during welding and affect the welding effect.

[0039] like Figures 6 to 9 As shown, a first circular ring 115 is slidingly provided inside the cleaning chamber 114, and a second scraper 117 is provided on the inner side of the first circular ring 115. The number of the second scrapers 117 is three, and each second scraper 117 is distributed in a circular array on the inner side of the first circular ring 115. A second circular ring 118 is provided on the inner wall of the cleaning chamber 114 away from the first circular ring 115, and a first scraper 116 is provided on the inner side of the second circular ring 118. The number of the first scrapers 116 is three, and each first scraper 116 is distributed in a circular array on the inner side of the first scraper 116. In use, the second circular ring 118 is controlled to rotate along the inner wall of the cleaning chamber 114, and the three first scrapers 116 are controlled to rotate with the second circular ring 118 during the rotation process, so that when the three first scrapers 116 rotate, the side of the first scraper 116 away from the second circular ring 118 is always in contact with the surface of the welding head in the welding machine 101, and the effect of scraping and cleaning the welding slag adhered to its surface is achieved.

[0040] It should be noted that: the first scraper 116 and the second scraper 117 are both made of copper wire (similar to a copper wire brush), and the materials of the first scraper 116 and the second scraper 117 are mature existing technologies, which can be used to clean the welding slag on the surface of the welding head in the welding machine 101, and will not be repeated here.

[0041] In order to adjust the first scraper 116 and the second scraper 117 so as to clean the welding slag with different degrees of adhesion, a return spring is provided on the side of one of the first scrapers 116 close to the second ring 118, and a hinge is provided at the connection between each of the first scrapers 116 and the second ring 118, and a hinge of the same type as the first scraper 116 is provided at the connection between the second scraper 117 and the first ring 115, and a second electric-controlled slide rail is provided on the side of the first ring 115 close to the cleaning chamber 114, and the second electric-controlled slide rail is respectively connected to the first ring 115 and the second ring 118. The two circular rings 118 are interconnected and used to control the first circular ring 115 and the second circular ring 118 to slide longitudinally along the inner wall of the cleaning chamber 114 through the second electrically-controlled slide rail. During use, the hinge controls the angles of the first scraper 116 and the second scraper 117, so that the intensity of the scraper cleaning can be changed, which is suitable for cleaning welding slag with different degrees of adhesion. In addition, the second electrically-controlled slide rail is controlled to change the positions of the first circular ring 115 and the second circular ring 118 respectively, so as to facilitate the cleaning of impurity welding slag on different parts of the welding joint, thereby achieving the purpose of increasing the cleaning area.

[0042] It should be noted that the model of the hinge on each first scraper 116 and the second scraper 117 is set to be an electric hinge, and the electric hinge has a built-in drive device. It is a mature existing technology and will not be repeated here. The areas where each first scraper 116 is distributed are respectively recorded as A, B, and C. A reset spring is provided on one side of the first scraper 116 located in area A, and the hinge in area A is initially in a power-off state (it can rotate to facilitate the detection of the position of welding slag adhesion in cooperation with the reset spring). The deflection direction of the second scraper 117 located on the second ring 118 is opposite to the deflection direction of the first scraper 116. In addition, micro motors are used on one side of the first ring 115 and the second ring 118 to control the first ring 115 and the second ring 118 to rotate along the inner wall of the cleaning chamber 114.

[0043] When the first ring 115 is in the first stage state, the second scraper 117 is completely fitted with the welding machine 101 on one side close to the welding machine 101, and the first ring 115 is in a clockwise rotation state. When the first ring 115 is in the second stage, the second ring 118 moves up along the second electric control push rod, and the first scraper 116 and the second scraper 117 contact each other. The first scraper 116 rotates along the hinge, and the edge of the first scraper 116 on one side close to the welding machine 101 fits with the welding machine 101. The first ring 115 and the second ring 118 rotate clockwise synchronously. When in use, the welding slag generated during welding adheres to the welding slag due to the different directions of the splatter. The adhesion degree of welding slag on the welding head of the welding machine 101 is also different. First, the optical sensor under the welding machine 101 is used to detect whether there is welding slag adhered to the welding head. At the same time, in order to detect the adhesion degree of welding slag on the welding head, the first scraper 116 in the A area and the reset spring are used to detect the compression amount of the reset spring to detect the adhesion degree of welding slag on the surface of the welding head of the welding machine 101. The cleaning strategy of the first scraper 116 and the second scraper 117 is adjusted in real time based on the detection data to prevent omissions after cleaning, so as to avoid the problem of reduced welding quality due to a large amount of welding slag adhered to the welding head of the welding slag welding machine 101. The specific steps are as follows:

[0044] It is worth noting that: an optical sensor located at the bottom of the welding machine 101 near the welding head is used to detect the surface of the welding head in the welding machine 101 to determine whether there is welding slag.

[0045] When the optical sensor detects that there is welding slag on the welding head of the welding machine 101 at this time, it means that when the welding slag generated during the welding process splashes outward, part of the welding slag contacts the surface of the welding head and thus adheres to the surface of the welding head. At this time, the control arm 109 controls the welding machine 101 to move along the first electric control slide rail 104 toward the cleaning bin 114 and moves to the top of the cleaning bin 114. Then, the welding machine 101 moves along the surface of the sliding block 105 toward the inside of the cleaning bin 114, so that the surface of the welding head at the bottom of the welding machine 101 is inserted into the inside of the cleaning bin 114, and the second ring 118 is controlled to rotate along the inside of the cleaning bin 114 through the micro motor. In this process, the first scraper 116 in the A area of ​​the three first scrapers 116 on the second ring 118 (please refer to Figure 8) is provided with a reset spring on one side. When the first scraper 116 contacts the welding slag, the welding slag will generate a thrust on the first scraper 116, causing the first scraper 116 to deflect through the cooperation of the hinge. At this time, the position where the welding slag adheres is determined by detecting the stretching amount of the reset spring. When the first scraper 116 deflects, it indicates that there is welding slag here. At this time, the micromotor on the second ring 118 is controlled to slow down, and the micromotor is set to rotate back and forth in a small amplitude, so that the first scraper 116 will frequently contact the welding slag and continuously scrape off the welding slag adhered to the welding head. After the scraping operation is completed, the micromotor on the second ring 118 is set to a normal rotation state, and the first scraper 116 in the A area is continued to be used to detect along the outer surface of the welding head in the welding machine 101. At the same time, the second electrically controlled slide rail is controlled to make the second ring 118 move longitudinally along the inner wall of the cleaning chamber 114, so as to achieve a comprehensive detection of the welding slag on the outer surface of the welding head.

[0046] If the return spring is not compressed and the first scraper 116 is not deflected during the contact with the welding head, the welding slag on the outer side of the welding head in the surface welding machine 101 has been completely removed. At this time, the first ring 115 is controlled to rotate so that the second scraper 117 rotates synchronously with the first ring 115. Since the first ring 115 is located at the bottom of the welding head, the welding slag near the welding point at the bottom of the welding head is cleaned by the second scraper 117. After completion, the welding operation can be continued, and the sliding block 105 is controlled to move the welding machine 101 upward to make the welding The welding head in the welding machine 101 leaves the cleaning chamber 114. After the welding head moves out of the cleaning chamber 114, in order to remove the welding slag scraped off during the scraping process, which will be re-adsorbed on the surface of the welding head due to static electricity or its own viscosity, the sliding block 105 is continued to be controlled to move the welding machine 101 upward, so that the welding point of the welding head in the welding machine 101 is located above the air nozzle 106. In this way, the driving motor 113 is started to cooperate with the air supply pipe 107 to blow air to the surface of the welding head on the welding machine 101 through the air nozzle 106, thereby achieving the purpose of cleaning the welding slag re-adsorbed on the welding head due to static electricity.

[0047] It should be noted that an electromagnetic slider is provided on one side of the welding machine 101 close to the sliding block 105, and the electromagnetic slider is slidably arranged inside one side of the sliding block 105. In this way, through the mutual cooperation between the sliding block 105 and the electromagnetic slider, the welding machine 101 can achieve the effect of longitudinal movement along one side of the sliding block 105.

[0048] If the reset spring is still compressed and the compression amount is small, it means that although the welding slag is cleaned by the first scraper 116, due to the high viscosity of the side of the welding slag close to the welding head, the first scraper 116 only scrapes off the outer surface part of the welding slag when scraping it, while the part close to the welding head is still adhered to the surface of the welding head, causing the reset spring to still be compressed. At this time, the first ring 115 is controlled to move along the second electric control slide rail toward the second ring 118, so that the side of the second scraper 117 close to the welding head contacts the first scraper 116. When the micro motor on the second ring 118 is turned on, the second scraper 117 applies pressure to the first scraper 116, and the second scraper 117 is used in the opposite direction to the first scraper 116. In this way, the deflection degree of the first scraper 116 is changed through the hinge to increase its cutting force. At the same time, the first ring 115 is turned on to rotate and keep consistent with the rotation speed of the second ring 118. At this time, the first scraper 116 and the second scraper 117 are in the same direction (please refer to the details). Fig. 9 ), when passing through welding slag, it will first contact with the cutting surface of the first scraper 116, and then contact with the cutting surface of the second scraper 117, so as to achieve the purpose of multi-layer scraping and realize the effect of cleaning welding slag with high adhesion.

[0049] When cleaning is completed, the first ring 115 and the second scraper 117 are controlled to move toward the bottom of the cleaning chamber 114. After returning to the initial position, the first ring 115 and the second ring 118 are controlled to move toward each other through the second electrically-controlled push rod, so that the top of the second scraper 117 will contact with the top of the first scraper 116 and produce a certain deformation. At this time, the first ring 115 and the second ring 118 are turned on to rotate synchronously, and the rotation speed is kept consistent. In this way, due to the change in shape of the first scraper 116 and the second scraper 117, the welding slag at the bottom will be rolled up during rotation. In this way, the wind nozzle 106 is facing the top of the cleaning chamber 114 so that the rolled-up welding slag can be absorbed, thereby achieving the effect of cleaning the cleaning chamber 114.

[0050] It is worth mentioning that in order to avoid scratching the welding head in the welding machine 101 during cleaning of welding slag, thereby shortening its service life, the materials of the first scraper 116 and the second scraper 117 are set to copper, so they have ductility and flexibility, and when the first scraper 116 and the second scraper 117 are squeezed against each other, they are deformed. In this process, airflow is generated during the movement of the first ring 115 and the second ring 118, and the height of the first ring 115 and the second ring 118 are changed synchronously with the second electric control slide rail, so as to roll up the welding slag at the bottom of the cleaning chamber 114. At the same time, with the negative pressure state of the air nozzle 106, the welding slag in the cleaning chamber 114 can be absorbed to achieve the effect of cleaning it.

[0051] In addition, after the welding slag in the cleaning chamber 114 is absorbed, the first ring 115 and the second ring 118 are controlled to rotate towards each other, so that the first scraper 116 and the second scraper 117 on the side close to the welding machine 101 will scrape each other and generate vibration through collision. In this process, the purpose of cleaning the surface of the first scraper 116 and the second scraper 117 is achieved.

[0052] In order to clean and collect the welding slag generated during the welding process, an air inlet blade is provided inside the air pumping bin 112. The output end of the drive motor 113 passes through the air pumping bin 112 and is arranged inside the air pumping bin 112. The side of the air inlet blade facing the drive motor 113 is connected to the drive motor 113 through the output end. During use, the drive motor 113 cooperates with the air inlet blade to generate suction for dust impurities. At this time, the air nozzle 106 and the air pipe 107 are cooperated to transport the dust impurities to the inside of the dust bin 110. After the dust impurities enter the dust bin 110, they will slide to the bottom of the dust bin 110 due to their own gravity, thereby achieving the effect of collecting dust impurities.

[0053] It should be noted that: there are two working modes for the drive motor 113 and the air inlet blades. In the initial working state, negative pressure will be generated at the air nozzle 106 to adsorb dust and impurities in the workpiece or the main body housing 201. At this time, the electric control air valve located in the exhaust pipe is set to an open state, so that the inhaled gas can be discharged to the outside through the exhaust pipe. When in the jet state, the drive motor 113 and the air inlet blades are reversed, and the electric control air valve located in the exhaust pipe is controlled to be set to a closed state to prevent the generated gas from being discharged to the outside along the exhaust pipe. At this time, the air nozzle 106 will blow gas to the outside.

[0054] like Figures 1 to 3As shown, in order to facilitate the operation of the device for welding, a pillar 204 is provided on the top of the main housing 201, and a bracket 205 is provided at one end of the pillar 204 away from the main housing 201, and a through hole is provided on the surface of the bracket 205. In order to avoid short circuit of the circuit board caused by high temperature during welding, a plurality of heat dissipation holes 206 are provided on the side of the main housing 201 close to the bracket 205, and each heat dissipation hole 206 is linearly arrayed on the surface of the main housing 201. In order to facilitate the operation of the device, a handle 207 and a control panel 202 are respectively provided on the front of the main housing 201, and the handle 207 is located on the upper part of the control panel 202. The four corners of the bottom of the main housing 201 are provided with foot pads 206. 03. When in use, a large amount of heat energy will be generated in the laser welding machine 101. At this time, a number of heat dissipation holes 206 located above the main housing 201 are used to discharge the heat generated in the welding machine 101 to the outside. In this way, the heat in the welding machine 101 can be discharged in time to avoid the situation where the internal high temperature causes a high-temperature short circuit of the circuit due to long-term operation. In order to avoid the shaking of the device during the welding process, which causes the welding to deviate and affects the welding quality, in addition, the control panel 202 is used to control the electrical components in the device to cooperate, so as to complete the welding work. At the same time, a pillar 204 and a bracket 205 are provided on the top of the main housing 201 for temporarily placing some welding materials to avoid loss.

[0055] The present invention also provides an anti-fiber winding assembly, including a laser welder of any of the above-mentioned technical solutions, the anti-fiber winding assembly is fixed inside the laser welder, and the anti-fiber winding assembly includes a stopper 108, the top of the stopper 108 is movably arranged on the inner top of the main body housing 201, and the bottom of the stopper 108 is provided with a compression spring 102, and the end of the compression spring 102 away from the stopper 108 is arranged on the surface of the optical fiber 103. When in use, the stopper 108 can be changed by the position change of the welding machine 101, so that the compression spring 102 is used to limit the state of the optical fiber 103, so as to avoid the frequent movement of the welding machine 101 during the welding process, which causes the optical fiber 103 to be wound, causing the optical fiber 103 to change the propagation path due to excessive bending during the transmission process. When the optical fiber 103 is bent to a certain extent, part of the light energy will penetrate into the cladding or pass through the cladding to become a radiation mode and leak outward, resulting in signal attenuation. At the same time, if the optical fiber 103 is seriously wound, stress may be generated inside the optical fiber 103, and even the optical fiber 103 may be broken. If the optical fiber 103 is broken, the laser signal cannot be transmitted at all, and the laser welding machine cannot work normally.
