Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of welding devices, in particular to a wind-cooled handheld laser welding machine. BACKGROUND

[0002] Laser welding is a kind of high-efficiency precision welding method using high-energy density laser beam as heat source. Laser welding is one of important aspects of laser material processing technology application. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding, and the welding process belongs to heat conduction type, that is, the surface of the workpiece is heated by laser radiation, and the internal heat is diffused through heat conduction, and by controlling the width, energy, peak power and repetition frequency of laser pulse and other parameters, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully applied to precision welding of micro and small parts.

[0003] The operator can perform welding work through the laser end head in the form of handheld welding gun structure, but in actual use, if the operator accidentally moves a long distance, the wire connected to the gun head will be too tight, and even if the moving distance exceeds the actual length of the wire, the wire will break, so improvement is needed. SUMMARY

[0004] In view of the defects of the prior art, the technical scheme adopted by the application to solve the technical problems is: a wind-cooled handheld laser welding machine, comprising: A container body, a control base is arranged at the bottom of the container body; An air inlet component is arranged at the right side of the inner cavity of the container body; A control console is arranged at the left side of the outer surface of the container body; Comprising: A handheld welding gun is clamped at the left side of the outer surface of the container body; A take-up device is arranged at the right side of the outer surface of the handheld welding gun and is used for performing wire laying work.

[0005] Further, the take-up device comprises: A lead box shell is fixedly connected to the outer surface of the container body; A winding roller shaft is symmetrically provided with a control motor at the shaft center through a rotating shaft, and the outer surface of the control motor is rotatably connected to the left side of the inner wall of the lead box shell; A transmission wire is wound around the outer surface of the winding roller shaft, one end of the transmission wire is inserted into the inner cavity of the container body, and the other end of the transmission wire is inserted into the inner cavity of the handheld welding gun, and the container body supplies power to the handheld welding gun through the transmission wire.

[0006] Further, the take-up device further comprises: The temperature control component is arranged at the right end of the lead box shell; The drainage device is arranged symmetrically at the right side of the inner cavity of the lead box shell. The damping component is arranged at the left side of the lead box shell through the outlet port.

[0007] Further, the damping component comprises: The buckle cover shell is provided with a guide port at the axial center of the inner cavity of the buckle cover shell, and the buckle cover shell is inserted into the outlet port of the lead box shell through the guide port. The inner diameter of the guide port of the buckle cover shell is greater than the outer diameter of the transmission lead. The control inner plate is fixedly connected with the inner wall of the buckle cover shell through the accommodating groove on the outer surface of the control inner plate. The outer drainage tube extends to the outside of the buckle cover shell at one end, and the other end of the outer drainage tube is inserted into the inner cavity of the control inner plate. The outer scanning end is uniformly arranged at the left side of the inner cavity of the control inner plate, and the outer scanning end extends to the outside of the control inner plate away from the control inner plate. The push-receiving component is symmetrically arranged at the upper and lower sides of the inner wall of the buckle cover shell. The control inner plate can judge the sliding distance of the transmission lead through the outer scanning end, absorb the external air through the outer drainage tube, and then pressurize the lower push-receiving component.

[0008] Further, the push-receiving component comprises: The sliding pressure plate is slidingly connected with the inner cavity of the buckle cover shell through the through-cut groove on the outer surface of the sliding pressure plate, and the bottom end of the sliding pressure plate extends to the inside of the guide port. The sliding pressure plate can slide out of the guide port of the buckle cover shell and slide to the position close to the transmission lead. The connecting push rod is inserted into the top of the inner cavity of the sliding pressure plate through the socket at the bottom end of the connecting push rod, and the top end of the connecting push rod is inserted into the bottom of the inner cavity of the control inner plate. The buffer spring sleeve is sleeved on the outer surface of the connecting push rod, one end of the buffer spring sleeve is fixedly connected with the outer surface of the control inner plate, and the other end of the buffer spring sleeve is fixedly connected with the outer surface of the sliding pressure plate.

[0009] Further, the push-receiving component further comprises: The buffer sliding plate is slidingly connected with the bottom of the inner wall of the sliding pressure plate on the outer surface of the buffer sliding plate. The buffer sliding plate is arranged at the bottom position of the sliding pressure plate, and under normal circumstances, the buffer sliding plate can contact the transmission lead earlier than the sliding pressure plate. The embedded ball is rollingly connected with the inner cavity of the buffer sliding plate on the outer surface of the embedded ball. The curved spring bands are symmetrically arranged on both sides of the outer surface of the buffer slide plate. One side of the curved spring band is fixedly connected to the inner wall of the sliding pressure plate, and the other side of the curved spring band is fixedly connected to the outer surface of the buffer slide plate. When the buffer slide plate is subjected to pressure, it will press the curved spring bands into the interior of the sliding pressure plate, thereby causing the buffer slide plate to completely retract into the interior of the sliding pressure plate.

[0010] Furthermore, the handheld welding torch includes: A handheld casing, the outer surface of which is snapped onto the outer surface of the container body via a clip; An adjustment knob, located at the bottom of the handheld casing, is used to adjust the laser power; The welding nozzle is located in the upper part of the inner cavity of the handheld casing and is used for direct laser welding. A trigger guard is rotatably connected to the left side of the outer surface of the handheld housing.

[0011] Furthermore, the drainage device includes: An external suction plate, the outer surface of which is snapped into the outer surface of the lead wire box shell; The adapter plate is evenly inserted into the exhaust groove of the outer suction plate, and the outer surface of the adapter plate extends into the interior of the lead box shell through a groove. A pressurized air duct is provided with compression connecting pipes evenly arranged in its inner cavity. The end of the compression connecting pipe away from the pressurized air duct is inserted into the inner cavity of the adapter plate. The outer suction plate adsorbs external air and blows air through the pressurized air duct to the position near the damping component.

[0012] Furthermore, the temperature control component includes: The insulation shell has its left end inserted into the right end of the lead wire box shell, and its outer surface is fixedly connected to the outer surface of the container body via a clip. A one-way rotating plate, the bottom end of which is rotatably connected to the inner wall of the insulation shell via a rotary roller shaft; The forced-air temperature chamber has its outer surface fixedly connected to the bottom of the inner wall of the insulation shell. Extendable pipes are evenly arranged on the side of the inner cavity of the forced-air temperature chamber near the one-way rotating plate. After the one-way rotating plate deflects, it will re-deflect due to the spring-like rebound action inside the rotary roller. Figure 7 At the position shown, the one-way rotating plates on the upper and lower sides are connected, isolating the blower chamber inside the insulation shell.

[0013] The beneficial effects of this invention are as follows: 1. This device can perform wire feeding by moving the winding roller in conjunction with the handheld welding gun. Since the operator may move the handheld welding gun beyond the actual maximum length of the transmission line, causing the transmission line to be stretched, deformed, or damaged, a damping component is installed on the left end of the lead box. This component gradually increases the resistance to the sliding of the transmission line according to the distance the operator moves the handheld welding gun, thus reminding the operator not to move the handheld welding gun too far, thereby protecting the transmission line.

[0014] 2. This device uses a pushing component to gradually apply pressure to the transmission wire that has slid a long distance. In order to avoid damage to the transmission wire due to excessive pressure and friction, the pushing component has been improved so that it does not wear the outer insulation of the transmission wire during the pressing process. It only increases the resistance of the transmission wire and does not completely stop the sliding movement of the transmission wire, making it easier for the operator to move the welding torch and not affecting normal operation.

[0015] 3. When the operator holds the handheld welding torch and performs welding work at a distance close to the wire take-up device, or after using the handheld welding torch and placing it back in its initial position, the flow-guiding device inside the lead wire box will blow air through the left opening of the lead wire box to cool the handheld welding torch near the opening and clean impurities from its outer surface. Since the pressurized air ducts on both sides can be moved through the compression connecting pipes, the pressurized air ducts can form a relatively concentrated airflow, avoiding the problem of poor blowing effect caused by the wind acting on the inner wall of the lead wire box.

[0016] 4. During cooling operations, the blower box located inside the insulation shell can cool the air according to the actual indoor temperature. The temperature control component continuously controls the temperature inside the lead wire box shell. In conjunction with the blower operation of the pressurized air duct, it cools down the handheld welding torch and the transmission wire. When not in operation, the one-way rotating plate will return to its original position due to the rebound action. At this time, the blower box is isolated from the lead wire box shell, avoiding the problem of dust being sucked in by the open structure of the wire take-up equipment, which would lead to excessive dust entering the blower box and reduce the cooling function.

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] Example 1, please refer to Figures 1-4 This invention provides a technical solution: an air-cooled handheld laser welding machine, comprising: Container body 1, with a control base 3 installed at the bottom of container body 1; Air inlet component 2 is located on the right side of the inner cavity of container body 1; Control console 4 is located on the left side of the outer surface of container body 1; include: Hold the welding torch 5 and attach it to the left side of the outer surface of the container body 1; The take-up device 6 is located on the right side of the outer surface of the handheld welding gun 5 and is used to perform the wire feeding operation.

[0021] The take-up device 6 includes: The outer surface of the lead wire box 61 is fixedly connected to the outer surface of the container body 1. The winding roller 62 has a control motor symmetrically arranged at its axis via a rotating shaft, and the outer surface of the control motor is rotatably connected to the left side of the inner wall of the lead wire box 61. The transmission wire 63 is wound around the outer surface of the winding roller 62. One end of the transmission wire 63 is inserted into the inner cavity of the container body 1, and the other end of the transmission wire 63 is inserted into the inner cavity of the handheld welding gun 5. The container body 1 supplies power to the handheld welding gun 5 through the transmission wire 63.

[0022] The take-up device 6 also includes: Temperature control component 8 is located at the right end of lead box housing 61; Drainage device 7, in two sets, is symmetrically arranged on the right side of the inner cavity of lead box 61; The damping component 9 is located on the left side of the lead box housing 61 through the cable outlet.

[0023] Damping component 9 includes: The cover 91 is fastened, and a guide port 92 is provided at the axis of the inner cavity of the cover 91. The cover 91 is inserted into the outlet of the lead box 61 through the guide port 92. The inner diameter of the guide port 92 of the cover 91 is larger than the outer diameter of the transmission wire 63. The control inner plate 93 has its outer surface fixedly connected to the inner wall of the snap-on cover 91 via a receiving groove. An external drainage tube 94, one end of which extends to the outside of the cover 91, and the other end of which is inserted into the inner cavity of the control inner plate 93. The external scanning end 95 is evenly arranged on the left side of the inner cavity of the control inner plate 93, and the end of the external scanning end 95 away from the control inner plate 93 extends to the outside of the control inner plate 93. The push-receiving component 96 is symmetrically arranged on the upper and lower sides of the inner wall of the cover shell 91. The control inner plate 93 can determine the sliding distance of the transmission wire 63 through the outer scanning end 95, absorb external air through the outer drainage pipe 94, and then pressurize it to the lower push-receiving component 96.

[0024] The pushed component 96 includes: The sliding pressure plate 961 has an outer surface that is slidably connected to the inner cavity of the cover 91 through a through groove, and the bottom end of the sliding pressure plate 961 extends into the interior of the guide opening 92. The sliding pressure plate 961 can slide out from the guide opening 92 of the cover 91 and slide closer to the transmission wire 63. Connecting push rod 965, the bottom end of connecting push rod 965 is inserted into the top of the inner cavity of sliding pressure plate 961 through the socket, and the top end of connecting push rod 965 is inserted into the bottom of the inner cavity of control inner plate 93. A buffer spring sleeve 966 is fitted onto the outer surface of the connecting push rod 965. One end of the buffer spring sleeve 966 is fixedly connected to the outer surface of the control inner plate 93, and the other end of the buffer spring sleeve 966 is fixedly connected to the outer surface of the sliding pressure plate 961.

[0025] The pushed component 96 also includes: The buffer slide plate 962 has its outer surface slidably connected to the bottom of the inner wall of the sliding pressure plate 961. The buffer slide plate 962 is located at the bottom of the sliding pressure plate 961. Under normal circumstances, the buffer slide plate 962 can contact the transmission wire 63 before the sliding pressure plate 961. The inner ball bearing 963 has its outer surface rolledly connected to the inner cavity of the buffer slide plate 962 via a slot. The curved spring band 964 is symmetrically arranged on both sides of the outer surface of the buffer slide plate 962. One side of the curved spring band 964 is fixedly connected to the inner wall of the sliding pressure plate 961, and the other side of the curved spring band 964 is fixedly connected to the outer surface of the buffer slide plate 962. When the buffer slide plate 962 is subjected to pressure, it will press the curved spring band 964 into the interior of the sliding pressure plate 961, thereby causing the buffer slide plate 962 to completely retract into the interior of the sliding pressure plate 961.

[0026] When using this device for welding, the operator removes the handheld welding torch 5, aligns it with the part to be welded, and performs direct welding. As the handheld welding torch 5 moves, it causes the internal transmission wire 63 to slide. Therefore, the winding roller 62 inside the lead wire box 61 needs to rotate to release the wire, thereby moving the handheld welding torch 5 and preventing the transmission wire 63 from being pulled off.

[0027] When the handheld welding torch 5 moves too far, the length of the transmission wire 63 that slides out of the lead wire housing 61 is also quite long. To avoid the problem that the length of the transmission wire 63 cannot keep up with the moving distance of the handheld welding torch 5, a damping component 9 is set at the opening. As the transmission wire 63 slides out from the guide opening 92, the control inner plate 93 records the sliding length of the transmission wire 63 through the external drain tube 94. After reaching a certain threshold, the control inner plate 93 will be automatically activated by the internal sensing device. The specific operation is as follows: The inner control plate 93 draws in air and pressurizes it through the external drainage pipe 94, then pushes the pushed component 96 into the guide port 92, that is, slides it close to the outer surface of the transmission wire 63. At this time, the sliding pressure plate 961 contacts the outer surface of the transmission wire 63 through the bottom buffer slide plate 962. The embedded ball bearings 963 gradually squeeze the transmission wire 63. At this time, the transmission wire 63 will be subject to gradually increasing resistance when sliding. However, the embedded ball bearings 963 will reduce the friction on the transmission wire 63 by rolling, and will not prevent the transmission wire 63 from continuing to slide. Therefore, after the operator feels the resistance, he will automatically slow down the distance of moving the handheld welding gun 5. If the operator continues to pull the handheld welding gun 5, the buffer slide plate 962 will retract into the interior of the sliding pressure plate 961 due to the pressing reaction force. The pressure of the sliding pressure plate 961 on the transmission wire 63 reaches the maximum value, and the transmission wire 63 is subjected to the maximum damping coefficient, effectively slowing down the speed of pulling the transmission wire 63.

[0028] When using the handheld welding torch 5, open the trigger protection shell 54, then adjust the adjustment knob 52 to change the laser emission power of the welding nozzle 53, align it with the part to be welded, and laser welding can be performed.

[0029] Example 2, please refer to Figures 1-7 The present invention provides a technical solution: based on embodiment 1, the handheld welding torch 5 includes: Handheld housing 51, the outer surface of which is snapped onto the outer surface of container body 1 via a clip; An adjustment knob 52, located at the bottom of the handheld housing 51, is used to adjust the laser power; The welding nozzle 53 is located in the upper part of the inner cavity of the handheld housing 51 and is used to directly perform laser welding work. Trigger housing 54 is rotatably connected to the left side of the outer surface of handheld housing 51.

[0030] Drainage device 7 includes: The outer surface of the outer suction plate 71 is snapped into the outer surface of the lead box housing 61. The adapter plate 72 is evenly inserted into the exhaust groove of the outer suction plate 71, and the outer surface of the adapter plate 72 extends into the interior of the lead box 61 through the groove. The pressurized air duct 74 has a compression connecting pipe 73 evenly arranged in its inner cavity. The end of the compression connecting pipe 73 away from the pressurized air duct 74 is inserted into the inner cavity of the adapter plate 72. The external suction plate 71 adsorbs external air and blows air through the pressurized air duct 74 to the position near the damping component 9.

[0031] Temperature control component 8 includes: The insulation shell 81 is inserted into the right end of the lead wire box shell 61 at its left end, and the outer surface of the insulation shell 81 is fixedly connected to the outer surface of the container body 1 through a clip. One-way rotating plate 82, the bottom end of which is rotatably connected to the inner wall of the heat preservation shell 81 via a rotary roller shaft; The outer surface of the forced-air temperature chamber 83 is fixedly connected to the bottom of the inner wall of the insulation shell 81. Extendable pipes 84 are evenly arranged on the side of the inner cavity of the forced-air temperature chamber 83 near the one-way rotating plate 82. After the one-way rotating plate 82 deflects, it will deflect back due to the spring rebound action inside the rotary roller. Figure 7 At the position shown, the one-way rotating plates 82 on the upper and lower sides are connected, isolating the blower box 83 inside the insulation shell 81.

[0032] When the operator holds the handheld welding torch 5 and performs welding work at a distance close to the wire take-up device 6, or after using the handheld welding torch 5 and placing it away... Figure 1 After reaching the indicated position, the airflow device 7 located inside the lead wire box 61 can also start working. The external suction plates 71 on both sides pressurize the external air into the interior of the adapter plate 72, and then guide it to the pressurized air duct 74 through the compression connecting pipe 73. The pressurized air duct 74 then compresses the air and sprays it out to the guide port 92 at the left end, thereby blowing air onto the handheld welding torch 5 and enabling the handheld welding torch 5 to cool down quickly. During this process, the actual extension and retraction length of the compression connecting pipe 73 can be adjusted by controlling the pressure of the external suction plates 71, thereby changing the actual air outlet position at the left end of the pressurized air duct 74 and making the airflow of the pressurized air ducts 74 on both sides more concentrated.

[0033] During cooling operations, the blower box 83 located inside the insulation shell 81 can cool the air according to the actual indoor temperature. The cooled air is then ejected through the extension pipe 84. At this time, the one-way rotating plate 82 will deflect towards the side closer to the lead wire box 61 due to the airflow, thereby opening the connection between the insulation shell 81 and the lead wire box 61. The temperature control component 8 continuously controls the temperature inside the lead wire box 61. In conjunction with the blower operation of the pressurized air pipe 74, the handheld welding torch 5 and the transmission wire 63 are cooled down. When not in operation, the one-way rotating plate 82 will return to its original position due to the rebound action. At this time, the blower box 83 is isolated from the lead wire box 61, preventing the open structure of the take-up device 6 from sucking in dust, which would cause excessive dust to enter the blower box 83 and reduce the cooling function.

[0034] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
