Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a handheld multi-degree-of-freedom laser welding auxiliary device. Background Art

[0002] A handheld welding gun is a portable laser welding device, usually used for small welding tasks. This device usually consists of a handheld welding gun and a laser generator. The handheld welding gun can focus the laser beam on the part that needs to be welded to achieve high-precision welding.

[0003] In existing manual welding operations, the welding position is usually determined, and then a welding mask or welding glass is placed between the eyes and the welding position to prevent the bright light generated during the welding process from directly shining into the eyes, causing temporary visual impairment or even permanent eye damage.

[0004] However, there are two problems in the existing shielding process. The first is the problem of convenience. Welding and protection cannot be integrated. Usually, you need to identify the welding position and then use another handheld welding mask or welding glass to block it, which is less convenient. At the same time, due to weather and light reasons, sometimes the welding position cannot be accurately determined after the welding mask or welding glass is blocked. It is necessary to readjust the above-mentioned repeated and tedious steps, which wastes time and affects efficiency.

[0005] Second: safety issues. If the welding mask or welding glass is not covered in time during welding, welding will begin before the shielding is completed. In this case, the bright light generated during welding will directly shine into the eyes, causing temporary visual impairment or even permanent eye damage.

[0006] In addition, during the metal welding process, there are some bends or corners that are extremely inconvenient for welding. When you don't want to cut and weld, the welder will fall into an awkward posture. Due to the narrow space or complex shape, it is difficult for the welder to easily perform the welding operation, which ultimately leads to poor weld quality and even desoldering / false welding problems.

[0007] Therefore, a handheld multi-degree-of-freedom laser welding auxiliary device is proposed to solve the above problems. Summary of the invention

[0008] In view of this, the technical problem to be solved by the present invention is to propose a handheld multi-degree-of-freedom laser welding auxiliary device which can effectively achieve welding and protection in one; can absorb welding slag during welding to prevent the slag from scattering and affecting welding; can adjust the welding angle when the welding angle is not good and affects welding; and can clean the welding slag on the welding device after welding is completed, so as to solve the problems existing in the prior art.

[0009] To achieve the above object, the present invention provides the following technical solutions: a handheld multi-degree-of-freedom laser welding auxiliary device, used for welding work, comprising: a grip, a squeeze trigger, wherein the grip is rotatably connected with the squeeze trigger, and the handheld multi-degree-of-freedom laser welding auxiliary device comprises: a multi-degree-of-freedom adjustment component and a welding auxiliary component, wherein the welding auxiliary component is located above the multi-degree-of-freedom adjustment component;

[0010] The multi-degree-of-freedom adjustment assembly includes an auxiliary plate fixedly connected to the bottom end of one side wall of the handle;

[0011] The welding auxiliary component includes a welding shielding sheet for shielding light during welding, and a gas transfer body is fixedly connected to the inner cavity of the grip.

[0012] As an improvement, the auxiliary plate is symmetrically fixedly connected with an arc track piece, an L-shaped support frame is arranged on the same vertical line of the auxiliary plate, an auxiliary through slot is opened on the L-shaped support frame, and a laser generator is fixedly connected to the inner wall of the L-shaped support frame.

[0013] As an improvement, the side walls of the L-shaped support frame are symmetrically fixedly connected with side wall A screws, and the side wall A screws are threadedly connected with tightening pieces. The arc track piece is located between the L-shaped support frame and the tightening piece. The L-shaped support frame is slidably connected to the arc groove of the trigger pull through the side wall A screws.

[0014] As an improvement, the L-shaped support frame is rotatably connected to a rotating wheel, the inner wall of the L-shaped support frame is fixedly connected to an auxiliary guide bar, the central axis of the rotating wheel is fixedly connected to a B screw, the other end of the B screw is rotatably connected to the auxiliary guide bar, and a threaded adapter block is laterally slidably connected to the auxiliary guide bar.

[0015] As an improvement, a connecting rod is rotatably connected to the bottom of the threaded adapter block, an adjustment plate is rotatably connected to the bottom of the L-shaped support frame, one end of the connecting rod away from the threaded adapter block is rotatably connected to the adjustment plate, and a welding head is fixedly connected to the bottom end surface of the adjustment plate.

[0016] As an improvement, the welding auxiliary component also includes a pushing column that slides laterally in the bottom end of the gas transfer body, the welding shielding plate slides laterally in the L-shaped support frame, one end of the pushing column is located in the gas transfer body and is laterally slidably connected to a push plate, a first return spring body and a push switch are fixedly connected to the push plate, the end of the first return spring body away from the push plate is fixedly connected to the inner cavity of the gas transfer body, and the top of the gas transfer body is connected to a one-way gas valve pipe.

[0017] As an improvement, one end of the welding shielding plate located in the inner cavity of the L-shaped support frame is fixedly connected to a second return spring body, a long column tube is fixedly connected inside the welding shielding plate, a circular ring tube is fixedly connected to the middle of the long column tube, and a rotating air release button is magnetically connected to the outer end of the long column tube.

[0018] As an improvement, an operating rod is fixedly connected to the rotating air-deflating button, and the operating rod is movably inserted in the long column tube. The end of the operating rod away from the rotating air-deflating button is fixedly connected to a sealing piece A, and the sealing piece A can be rotatably connected in the inner cavity of the long column tube.

[0019] As an improvement, the annular tube is connected to the long column tube, and an air blowing port is provided at the bottom of the annular tube.

[0020] As an improvement, both the A blocking piece and the B blocking piece are configured to be notch-shaped.

[0021] Compared with the prior art, the present invention provides a handheld multi-degree-of-freedom laser welding auxiliary device, which has the following beneficial effects:

[0022] 1. Through the setting of the welding auxiliary component, the welding shielding sheet will automatically extend before the welder squeezes the trigger to perform welding work, so as to ensure that the bright welding light is timely shielded during welding. In this way, welding and protection are integrated in terms of convenience, while also improving safety. Unlike the prior art, the prior art often fails to shield the welding mask or welding shielding sheet in time during welding, resulting in bright light directly hitting the eyes during welding, which may cause temporary visual impairment or permanent eye damage. This integrated setting avoids the need for the operator to identify the welding position and then use another handheld welding mask or welding shielding sheet to block it, thereby improving the convenience of operation;

[0023] In addition, this setting also avoids the situation where the operator cannot accurately judge the welding position due to weather and light reasons, and needs to repeatedly adjust the operation steps, wasting time and affecting efficiency. Therefore, this new setting not only improves work efficiency, but also effectively ensures the safety of welders.

[0024] 2. Through the setting of welding shielding sheet, in addition to shielding the strong welding light during welding to avoid visual damage, the welding head can also shield the splashing welding slag generated at the welding position during welding, so as to prevent the molten metal welding slag from splashing on the skin of the welder and causing skin burns, and splashing into the eyes of the welder and causing eye damage problems such as eye stinging, redness, swelling, and tears.

[0025] 3. The auxiliary plate, L-shaped support frame and welding shielding sheet extending from the L-shaped support frame can not only shield the scattered welding slag during welding, but also prevent the molten metal welding slag from flying onto the welder's skin and causing burns, and from entering the welder's eyes and causing eye injuries such as eye stinging, redness, swelling and tears. This setting helps to reduce the unevenness caused by metal welding slag remaining on the welded metal surface, and can also effectively reduce the time cost of handling the welding slag splashes and improve efficiency.

[0026] 4. The gas entering from the one-way air valve tube into the inner cavity of the L-shaped support frame, the long column tube and the circular tube is used to indirectly push the welding shielding plate. After the subsequent welding is completed, the gas used to push the welding shielding plate to move can also be released from the blowing port at the bottom of the circular tube after rotating the air release button, so as to clean the surface of the welding head, effectively avoiding the residual welding slag that will increase the friction resistance of the welding head during the welding process, reduce the welding speed, and reduce the welding efficiency. There will also be no residual accumulation of welding slag inside the welding head, causing equipment failure or even fire and other safety problems, effectively ensuring the feasibility of welding quality, production efficiency and equipment life.

[0027] 5. Through the setting of multi-degree-of-freedom adjustment components, different from the situation in the prior art where the welding head cannot be adjusted, this design that can effectively adjust the angle and position of the welding head during welding work can effectively avoid the inconvenience of welding bends or corner pulls during welding, and prevent welders from falling into uncomfortable postures, making it difficult to perform welding operations due to narrow space or complex shapes, ultimately leading to poor weld quality or even desoldering / cold weld problems; at the same time, based on the adjustable angle, some inconvenient welding positions do not need to be cut and welded as in the prior art, thereby improving the overall quality of welded parts and the subsequent stability of use.

[0051] in:

[0053] The auxiliary through slot 304 is mainly used to cooperate with the welding head 314 when adjusting the position.

[0054] The laser generator 305 is connected to the welding head 314 via a line.

[0056] The B screw rod 310 is matched with the thread adapter block 311 .

[0057] For further examples, please refer to Figure 1 , Figure 4 , Figures 7 to 13 As shown:

[0058] The welding auxiliary component 4 includes a welding shielding sheet 400 for shielding light during welding, a gas transfer body 401 is fixedly connected in the inner cavity of the handle 1, and the welding auxiliary component 4 also includes a pushing column 402 that slides laterally in the bottom end of the gas transfer body 401, the welding shielding sheet 400 slides laterally in the L-shaped support frame 303, one end of the pushing column 402 is located in the gas transfer body 401 and is laterally slidably connected to a push plate 403, a first return spring body 404 and a press switch 413 are fixedly connected to the push plate 403, the end of the first return spring body 404 away from the push plate 403 is fixedly connected to the inner cavity of the gas transfer body 401, and the top of the gas transfer body 401 is connected to a one-way gas valve Tube 405, one end of the welding shielding piece 400 located in the inner cavity of the L-shaped support frame 303 is fixedly connected to the second return spring body 406, a long column tube 407 is fixedly connected inside the welding shielding piece 400, a circular ring tube 408 is fixedly connected to the middle part of the long column tube 407, the outer end of the long column tube 407 is magnetically connected to a rotating air release button 409, the rotating air release button 409 is fixedly connected to an operating rod 410, the operating rod 410 is movably inserted in the long column tube 407, the end of the operating rod 410 away from the rotating air release button 409 is fixedly connected to an A plugging piece 411, the A plugging piece 411 can be rotatably connected in the inner cavity of the long column tube 407, and the long column tube 407 is fixedly connected to a B plugging piece 412.

[0059] in:

[0060] The welding auxiliary component 4 is mainly used to adjust the angle when the welding angle is not good and affects the welding. At the same time, it receives the welding slag dropped during welding and cleans the welding slag on the welding device after welding is completed.

[0061] The handle 1 and the bottom of the gas transfer body 401 are both provided with through holes for assisting air intake.

[0062] The annular tube 408 is connected to the long column tube 407 , and an air blowing port is provided at the bottom of the annular tube 408 .

[0063] The L-shaped support frame 303 and the rotating air release button 409 are in contact with each other and are magnetic, and are mainly used for magnetic fixation of the rotating air release button 409 .

[0064] The A plugging piece 411 and the B plugging piece 412 are both configured in a notch shape and are mainly used by being displaced when in use, so as to release the gas in the long column tube 407 .

[0065] There is an electrical connection between the push switch 413 and the laser generator 305. When the push switch 413 is pressed, the laser generator 305 energizes the welding head 314 to generate arc welding conditions.

[0066] Everything in the above example works like this:

[0067] In the initial state:

[0068] The welding shielding piece 400 is located in the L-shaped support frame 303, the pushing column 402 is not squeezed by the trigger 2, the air pushing piece 403 does not push the gas in the gas transfer body 401, the first return spring body 404 is not compressed, the second return spring body 406 is not stretched, the A blocking piece 411 and the B blocking piece 412 are in a misaligned state, and the gas cannot pass through at this time, and the push switch 413 is not pressed.

[0069] The following is the working process of the multi-degree-of-freedom adjustment component 3:

[0070] If the welding position is difficult to handle and the angle and orientation of the welding head 314 need to be adjusted, the multi-degree-of-freedom adjustment component 3 is required:

[0071] When adjusting the angle, refer to Figure 2 At this time, the fastening piece 307 on the screw rod 306 of the side wall A is rotated to loosen the arc track piece 302 that was originally fastened to the fastening piece 307 and close to the side wall of the L-shaped support frame 303. Further, after the arc track piece 302 is loosened, the welding personnel manually adjust the angle of the L-shaped support frame 303. After the angle adjustment is completed, the loosened fastening piece 307 is rotated in the opposite direction again to tighten the L-shaped support frame 303 that is in a loose state after adjustment. At this time, the position of the L-shaped support frame 303 is in a fixed state, and the welding head 314 indirectly fixed on the L-shaped support frame 303 is in an adjusted and fixed state. Please refer to Figure 6 ;

[0072] When adjusting the position, refer to Figure 6 First, the welder rotates the rotating wheel 308. At this time, the B screw 310 located in the auxiliary guide bar 309 and threadedly connected to the thread adapter block 311 will rotate synchronously with the rotating wheel 308. As the B screw 310 continues to rotate, the thread adapter block 311 will move in the auxiliary guide bar 309. At this time, with the assistance of the connecting rod 312, the connecting rod 312 will lead the adjustment plate 313 to rotate with the hinged fixed position on the inner wall of the L-shaped support frame 303 as the rotation axis. During the rotation of the adjustment plate 313, the welding head 314 fixed thereon will move its position with the assistance of the auxiliary through slot 304 opened on the L-shaped support frame 303, thereby completing the adjustment work;

[0073] That is, through the setting of the multi-degree-of-freedom adjustment component 3, the angle and position of the welding head 314 can be effectively adjusted during welding, which is different from the situation in the prior art where the welding head 314 cannot be moved and adjusted, and avoids the situation where there are some bends or corners during welding that are extremely inconvenient for welding work. It can effectively prevent welders from falling into awkward postures, and it is difficult to perform welding operations easily due to narrow space or complex shapes, which ultimately leads to poor weld quality and even desoldering / cold welding problems. At the same time, based on the adjustable angle, there is no need to perform cutting and welding operations for some inconvenient welding positions as in the prior art.

[0074] Please refer to the above working process Figures 1 to 3 , Figures 5 and 6 .

[0075] The following is the working process of the welding auxiliary component 4:

[0076] Furthermore, when welding, the welder will squeeze the trigger 2 to squeeze the pushing column 402 on one side, and the squeezed pushing column 402 will move with the pushing sheet 403 at the bottom of the gas transfer body 401. For details, please refer to Figure 7 as well as Figure 8, when the air pusher 403 moves laterally, the gas in the air pusher 403 will enter the L-shaped support frame 303 through the one-way air valve tube 405 at the top, and the first return spring body 404 will be compressed. Further, as the gas enters the L-shaped support frame 303 from the gas transfer body 401 through the one-way air valve tube 405 and continues to enter the long column tube 407 and the circular ring tube 408 connected thereto, the second return spring body 406 in the L-shaped support frame 303 will be stretched during the outward movement of the welding shielding plate 400; further, after the welding shielding plate 400 has completed its outward movement, the push switch 413 on the air pusher 403 that moves laterally in the gas transfer body 401 will be squeezed onto the inner cavity wall of the gas transfer body 401, and the laser generator 305 connected thereto will energize the welding head 314 through the connecting line to perform welding;

[0077] Furthermore, after welding is completed, the entire welding device, especially the surface of the welding head 314, needs to be cleaned and maintained. At this time, only the air release button 409 needs to be rotated. During the rotation of the air release button 409, the operating rod 410 fixedly connected to it will carry the A plugging piece 411 to rotate in the inner cavity of the long column tube 407. At this time, the A plugging piece 411 and the B plugging piece 412 in the misaligned state will no longer be misaligned to block the air on the left side of the long column tube 407. At this time, the gas will enter the circular tube 408 connected to the long column tube 407 from the long column tube 407. Further, the gas will be discharged from the blowing port at the bottom of the circular tube 408, so as to clean and blow the welding head 314 and its vicinity;

[0078] Furthermore, in the setting of the welding auxiliary component 4, before the welder squeezes the trigger 2 to start welding, the welding shielding piece 400 will automatically extend to ensure that the bright welding light is timely shielded during welding, so that welding and protection are integrated in terms of convenience, and safety is also improved. This is different from the prior art in which the welding mask or welding shielding piece 400 is not shielded in time during welding, that is, the welding work begins before the shielding is completed, resulting in the bright light generated in the welding process directly irradiating the eyes, causing temporary visual impairment or even permanent eye damage. At the same time, this integrated setting is different from the prior art in which the operator usually needs to identify the welding position and then use the other hand to hold the welding mask or welding shielding piece 400 for shielding, which is less convenient. At the same time, this setting will not cause the operator to block the welding position accurately after blocking the welding mask or welding shielding piece 400 due to weather and light reasons, and it is necessary to readjust the repeated and cumbersome steps of the above operations, wasting time and affecting efficiency.

[0079] Furthermore, by setting the welding shielding sheet 400, in addition to blocking strong light during welding to prevent visual impairment, it can also block the slag splashing generated at the welding position, effectively preventing the molten metal slag from splashing onto the welder's skin to cause burns, or splashing into the eyes to cause eye stinging, redness, swelling, tears, etc. Such a setting not only improves the safety of the operation, but also avoids cumbersome operating steps and time waste, further improving efficiency.

[0080] Furthermore, by configuring the auxiliary plate 301, the L-shaped support frame 303 and the welding shielding sheet 400 extending from the L-shaped support frame 303, the splattered welding slag can be shielded during the welding process. This configuration can reduce the amount of molten metal welding slag that falls onto the metal surface and remains on the metal surface after cooling, causing unevenness of the welded metal parts. At the same time, this shielding can effectively reduce the time cost of handling the splattered welding slag after welding is completed.

[0081] Furthermore, the gas entering the L-shaped support frame 303 and the inner cavities of the long column tube 407 and the circular tube 408 from the one-way air valve tube 405 is used to indirectly push the welding shielding plate 400. After the subsequent welding is completed, the gas used to push the welding shielding plate 400 to move can also be discharged from the blowing port at the bottom of the circular tube 408 after rotating the exhaust button 409, so as to clean the surface of the welded welding head 314, effectively avoiding the residual welding slag that will increase the friction resistance of the welding head 314 during the welding process, reduce the welding speed, and reduce the welding efficiency. There will also be no residual accumulation of welding slag inside the welding head 314, causing equipment failure or even fire and other safety problems, effectively ensuring the feasibility of welding quality, production efficiency, and equipment life.

[0082] Please refer to the above working process Figure 1 , Figure 4 , Figures 7 to 13 .

[0083] Summary: Through the setting of the multi-degree-of-freedom adjustment component 3, the angle and position of the welding head 314 during welding can be effectively adjusted. Unlike the prior art, the welding head 314 can be moved and adjusted to avoid inconvenient welding positions during welding. This effectively prevents welders from falling into uncomfortable postures, which make it difficult to perform welding operations due to narrow spaces or complex shapes, ultimately leading to poor weld quality and even desoldering / false welding problems. At the same time, based on the adjustable angle, some inconvenient welding positions do not need to be cut and welded as in the prior art. At the same time, under the setting of the welding auxiliary component 4, the welding shielding sheet 400 can be automatically extended before the welder presses the trigger 2 to perform welding work to ensure that the bright welding light is timely shielded during welding. In terms of convenience, welding and protection are integrated, which is different from the prior art in which the welding mask or welding shielding piece 400 is not blocked in time during welding, that is, the welding work begins before the blocking is completed, resulting in the bright light generated in the welding process directly shining on the eyes, causing temporary visual impairment or even permanent eye damage. At the same time, this integrated setting is different from the prior art in which the operator usually needs to identify the welding position and then use the other hand to hold the welding mask or welding shielding piece 400 for blocking, which is less convenient. At the same time, this setting will not cause the operator to block the welding position accurately after blocking the welding mask or welding shielding piece 400 due to weather and light reasons, and it will not need to readjust the repeated and tedious steps of the above operations, wasting time and affecting efficiency.
