[0046] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0049] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of some applications, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0050] Combination Figure 1 , Figure 2 and Figure 3 As shown, the present application provides a welding jig, including a base 100, the base 100 is used to support a first component 800, wherein the first component 800 includes a plurality of welding positions 810, and a plurality of welding grooves 200 are arranged on the base 100, each welding groove 200 can accommodate at least one welding position 810 of the first component 800 and a second component 900 to be welded with the welding component.

[0051] Furthermore, on two opposite side walls of each welding groove 200 , one side wall is provided with an air outlet 310 , and the other side wall is provided with an air inlet 320 . The air outlet 310 and the air inlet 320 cooperate to form airflow in the welding groove 200 .

[0052] In the welding fixture of the present application, a plurality of welding grooves 200 are arranged on the base 100, the base 100 supports the first component 800 and makes the welding parts 810 of the first component 800 respectively located in the corresponding welding grooves 200, and then the second component 900 is respectively placed in the welding grooves 200 and welded with the corresponding welding parts 810 of the first component 800. Since one of the two opposite side walls of each welding groove 200 is provided with an air outlet 310 and the other is provided with an air inlet 320, each welding part 810 of the first component 800 can be welded to the welding groove 200 during the welding process with the second component 900. The air outlet 310 provided in the corresponding welding groove 200 can be provided to the welding groove 200. 00, the protective gas can blow away the plasma gas generated in the welding process in time, and the air inlet 320 arranged in the corresponding welding groove 200 can continuously exhaust the welding groove 200, and because the air outlet 310 and the air inlet 320 are respectively arranged on the side walls of the welding groove 200 that are opposite to each other, the air outlet of the air outlet 310 and the air exhaust of the air inlet 320 form a continuously flowing airflow in the welding groove 200. In this way, it can be ensured that during the welding process in the welding groove 200, the generated plasma gas is blown away in time, and the generated dust is exhausted, thereby ensuring the welding quality of each welding part 810 in the first component 800 and the second component 900.

[0053] Specifically, in some embodiments, the first component 800 may be a motor controller, the welding portion 810 of the first component 800 may be a pin on the motor controller, and there may be multiple pins on the motor controller, and the multiple pins may be respectively located on both sides of the motor controller, and the second component 900 may be a conductive sheet, and a conductive sheet may be respectively welded to each pin on the motor controller.

[0054] When the welding jig is in use, the motor controller (first component 800) is placed on the base 100, and the pins of the motor controller (welding portion 810 of the first component 800) are located in the welding slot 200, wherein the number of pins placed in the same welding slot 200 can be one, two, three, etc., and the number of pins that can be accommodated in a welding slot 200 can be determined based on the width of each pin and the interval between adjacent pins. Then the conductive sheet (second component 900) is placed in the welding slot 200 and in contact with the pins, so as to facilitate the subsequent welding of the pins and the conductive sheet together.

[0055] See also Figure 3In some embodiments, a plurality of fixing members 300 may be provided on the base 100, and the plurality of fixing members 300 are arranged at intervals, and a welding groove 200 is formed between each two adjacent fixing members 300, and among the two adjacent fixing members 300, an air outlet 310 is provided on a side of one of the fixing members 300 close to the welding groove 200, and an air inlet 320 is provided on a side of the other fixing member 300 close to the welding groove 200. It should be noted that the above-mentioned welding groove 200 refers to the welding groove 200 formed by two adjacent fixing members 300.

[0056] The above structure facilitates the formation of the welding groove 200 on the base 100 , and at the same time, facilitates the arrangement of the air inlet 320 and the air outlet 310 .

[0057] For example, the air inlet hole 320 or the air outlet hole 310 may be processed on the fixing member 300 first, and then the fixing member 300 is disposed on the base 100 to form the welding groove 200 .

[0058] Further, see Figure 5 In some embodiments, a through hole 330 that connects the welding grooves 200 on both sides may be provided on the fixing member 300 between two adjacent welding grooves 200 , and the through hole 330 is formed as an air outlet 310 or an air inlet 320 .

[0059] It can be understood that in some embodiments, the fixing piece 300 between two adjacent welding grooves 200 may be the same. In this case, a through hole 330 is set on the fixing piece 300 to connect the welding grooves 200 on both sides. The through hole 330 can blow or exhaust air to the welding grooves 200 on both sides at the same time, that is, the through hole 330 can form an air inlet 320 or an air outlet 310 of two adjacent welding grooves 200. In this way, there is no need to set an air inlet 320 or an air outlet 310 corresponding to each welding groove 200 on a fixing piece 300, which is beneficial to the production and processing of welding jigs.

[0060] For example, when three fixing members 300 are arranged on the base 100 in sequence, the three fixing members 300 can form two welding grooves 200. At this time, a through hole 330 that is respectively connected to the welding grooves 200 on both sides can be set on the middle fixing member 300. If the through hole 330 is used to blow air into the welding groove 200, that is, the through hole 330 on the middle fixing member 300 is formed as an air outlet 310 for blowing air into the air-avoiding grooves 130 on both sides, then the other two fixing members 300 can be provided with an air inlet 320 for exhausting air from the welding groove 200.

[0061] See also Figure 1 , Figure 2 , Figure 3 and Figure 7An air guide member 400 may also be provided on the base 100 , and a first air guide channel 410 and a second air guide channel 420 are provided on the air guide member 400 . The first air guide channel 410 is respectively connected to the air outlet hole 310 , and the second air guide channel 420 is respectively connected to the air inlet hole 320 .

[0062] It can be understood that since a plurality of welding grooves 200 are provided on the base 100, and an air inlet 320 and an air outlet 310 are respectively provided on two opposite side walls of each welding groove 200, this means that the number of air inlet holes 320 and air outlet holes 310 on the welding jig is relatively large. If each air inlet hole 320 and air outlet hole 310 are respectively connected to an air pipe, the structure of the welding jig will be complicated. Therefore, in the above method, an air guide member 400 is provided, and a first air guide channel 410 and a second air guide channel 420 are provided on the air guide member 400, so that the first air guide channel 410 is respectively connected to the plurality of air outlet holes 310, and the second air guide channel 420 is respectively connected to the plurality of air inlet holes 320. In this way, positive pressure gas can be conveniently introduced into the plurality of air outlet holes 310 at the same time, and negative pressure gas can be conveniently introduced into the plurality of air inlet holes 320 at the same time.

[0063] Specifically, the air guide member 400 can be arranged on the side of the multiple fixing members 300 away from the first member 800, and respectively abut against the fixing members 300. In some embodiments, the air guide member 400 and the fixing members 300 can be sealed by applying sealing glue or adding a sealing member. The air guide member 400 can be respectively provided with first air holes (not shown in the figure) connecting the air outlet hole 310 and the first air guide channel 410, and the air guide member 400 can be respectively provided with second air holes (not shown in the figure) connecting the air inlet hole 320 and the second air guide channel 420.

[0064] In some embodiments, an air duct 340 is also provided on the fixing member 300. When the fixing member 300 is provided with an air outlet hole 310, the air duct 340 is used to connect the air outlet hole 310 and the first air hole. When the fixing member 300 is provided with an air inlet hole 320, the air duct 340 is used to connect the air inlet hole 320 and the second air hole.

[0065] See also Figure 3 In some embodiments, a support position for supporting the first component 800 is provided on the base 100, and a plurality of welding grooves 200 are respectively provided on opposite sides of the support position. For example, when the first component 800 is a motor controller, a plurality of pins are provided on both sides of the motor controller, so when the motor controller is located on the support position, the pins on both sides of the motor controller can be respectively located in the corresponding welding grooves 200.

[0066] Furthermore, an air guide member 400 is respectively provided corresponding to the multiple welding grooves 200 on each side of the support position, and a blowing member 500 and an exhaust member 600 may also be respectively provided at the opposite ends of the support position. The blowing member 500 is provided with a blowing channel (not shown in the figure), and the two ends of the blowing channel are respectively connected to the first channel in the air guide members 400 on both sides. The exhaust member 600 is provided with an exhaust channel (not shown in the figure), and the two ends of the exhaust channel are respectively connected to the second channel in the air guide members 400 on both sides.

[0067] It can be understood that in the present application, the relative two sides of the support position refer to the side positions of the support position, and the relative two ends of the support member refer to the end surface positions of the support member, wherein the side surface and end surface of the support member are two adjacent surfaces.

[0068] Specifically, by introducing positive-pressure gas into the blowing channel of the blowing member 500, the positive-pressure gas can be introduced into the first air guide channels 410 of the fixing members 300 on both sides, and then introduced into the corresponding air outlet holes 310 respectively through the first air guide channels 410; by introducing negative-pressure gas into the exhaust channel of the exhaust member 600, the negative-pressure gas can be introduced into the second air guide channels 420 of the fixing members 300 on both sides, and then introduced into the corresponding air inlet holes 320 respectively through the second air guide channels 420.

[0069] It can be seen that the above method can facilitate the simultaneous introduction of positive pressure gas into the multiple air outlet holes 310 on both sides of the support position, and can facilitate the simultaneous introduction of negative pressure gas into the multiple air inlet holes 320 on both sides of the support position.

[0070] See also Figure 3 The air guide 400 can be arranged on the side of the welding groove 200 away from the supporting position, and the air guide 400, the air blowing member 500 and the air extraction member 600 enclose a processing area, and the processing area includes the supporting position and the welding groove 200. In this way, during the welding process, it is helpful to limit the generated gas and dust in the processing area, and reduce or avoid spreading outside the welding fixture.

[0071] See also Figure 3 A first limiting groove 110 may also be provided on the base 100 , and the first limiting groove 110 is used to limit the first component 800 to achieve positioning of the first component 800 on the base 100 .

[0072] A second limiting groove 120 may be provided in the welding groove 200 , and the second limiting groove 120 is used to limit the second component 900 .

[0073] It can be understood that since the welding part 810 of the first component 800 is located on the first component 800, once the first component 800 is positioned, the positioning of the welding component in the welding groove 200 can be achieved. At the same time, the second component 900 is positioned in the welding groove 200, and the welding positioning between the second component 900 and the welding component is achieved, thereby ensuring the accuracy of welding.

[0074] Furthermore, a void 130 may be provided in the welding groove 200 corresponding to the welding position 810 of the first component 800 .

[0075] In some embodiments, the avoidance 130 may be a avoidance 130 groove or a avoidance 130 hole provided on the base 100 within the welding groove 200 .

[0076] It can be understood that when the laser is used to weld the welding portion 810 of the first component 800 , the gap 130 can prevent the base 100 and the welding portion 810 from being welded together.

[0077] See also Figure 8 and Fig. 9 The welding jig may further include a pressing structure 700 , and the pressing structure 700 is used to press the welding position 810 of the first component 800 and the second component 900 .

[0078] Specifically, the pressing structure 700 may include a pressing member 710, a first pressing head 720, and a second pressing head 730. The pressing member 710 is detachably connected to the base 100, the first pressing head 720 and the second pressing head 730 are relatively arranged on the pressing member 710, the first pressing head 720 is used to press one end of the second component 900 onto the welding area of ​​the first component 800, and the second pressing head 730 is used to press the other end of the second component 900 onto the welding area of ​​the first component 800, a welding channel 740 is arranged between the first pressing head 720 and the second pressing head 730, the welding channel 740 corresponds to the welding position 810 of the first component 800, and a welding hole 750 is arranged on the pressing member 710 corresponding to the welding channel 740.

[0079] Before welding, the clamping piece 710 is installed on the base 100, and the first pressing head 720 presses the first component 800 on the base 100. Preferably, the first pressing head 720 is used to press one end of the second component 900 on the welding area of ​​the first component 800, and the second pressing head 730 is used to press the other end of the second component 900 on the welding area of ​​the first component 800, to ensure that the first component 800 and the second component 900 fit well up and down without warping and gap. Then, the laser is used to weld the welding part 810 of the first component 800 and the second component 900 through the welding hole 750 and the welding channel 740, so that the welding part 810 of the first component 800 and the second component 900 are welded together.

[0080] Furthermore, in order to facilitate the detachable connection between the clamping member 710 and the base 100, a first clamping member 760a may be provided on the base 100, and a second clamping member 760b may be provided on the clamping member 710, and the second clamping member 760b may be rotated relative to the clamping member 710, and an elastic member 790 is provided between the second clamping member 760b and the clamping member 710, and the elastic member 790 causes the second clamping member 760b to rotate, thereby causing the second clamping member 760b and the first clamping member 760a to clamp each other.

[0081] Specifically, when the first clamping member 760a and the second clamping member 760b are clamped to each other, the elastic member 790 can make the second clamping member 760b rotate on the pressing member 710 in a direction close to the first clamping member 760a, so that the pressing structure 700 is connected to the base 100, wherein the elastic member 790 can be a spring. When the pressing structure 700 needs to be removed from the base 100, the second clamping member 760b can be manually rotated on the pressing member 710 in a direction away from the first clamping member 760a, so that the second clamping member 760b is separated from the first clamping member 760a.

[0082] Furthermore, a first positioning portion 770a may be provided on the base 100, and a second positioning portion 770b may be provided on the clamping member 710. The first positioning portion 770a and the second positioning portion 770b cooperate to position the clamping member 710 on the base 100, thereby achieving precise assembly of the clamping structure 700 and the base 100, thereby ensuring that the first pressing head 720 and the second pressing head 730 can respectively accurately clamp the first component 800 and the second component 900.

[0083] The first positioning portion 770a may be a positioning column disposed on the base 100, and the second positioning portion 770b may be a positioning hole disposed on the pressing member 710. There may be a plurality of first positioning portions 770a and second positioning portions 770b.

[0084] Furthermore, a screw hole 780a may be provided on the base 100, and a bolt 780b may be provided on the clamping member 710. The bolt 780b cooperates with the screw hole 780a to fix the clamping member 710 on the base 100 to prevent loosening between the clamping structure 700 and the base 100, thereby affecting the clamping position of the first pressure head 720 and the second pressure head 730.

[0085] The present application also provides a welding device, including a laser and the welding jig in the above embodiment, the laser and the welding jig are arranged opposite to each other, and the laser is used to weld the first component 800 and the second component 900 on the welding jig.

[0086] Specifically, the laser emitted by the laser can act on the welding position 810 between the first component 800 and the second component 900 through the welding hole 750 on the clamping piece 710 and the welding channel 740 between the first pressing head 720 and the second pressing head 730 in turn, thereby realizing the welding of the first component 800 and the second component 900.

[0087] The above are only preferred embodiments of the present application and are not intended to limit the present application.
