[0043] Reference Figure 1 , Figure 2 and Figure 4 According to the jig of the embodiment of the present application, the jig includes a first carrier 100, a first fixing member 200 and a second fixing member 300.

The first fixing member 200 and the second fixing member 300 respectively realize the abutment and fixation of the circuit board 130 and the component 140, ensure the mutual positioning of the circuit board 130 and the component 140, and improve the positioning stability. On the other hand, by the abutting portion 320 pressing against the component 140, the pressure of the component 140 pressing against the circuit board 130 can be stably controlled, the probability of poor solder joints, leaky solder joints, etc. can be reduced, and the welding effect can be ensured.

[0044] Reference Figure 1 and Figure 2In some embodiments, the first fixing member 200 is movably connected to the first carrier plate 100 , and the first fixing member 200 can move to be offset from the first receiving groove 110 in the first direction to facilitate loading and removal of the circuit board 130 .

[0045] Reference Figure 1 and Figure 2 In some embodiments, the first fixing member 200 is rotatably connected to the first carrier 100, and the first fixing member 200 can rotate around an axis extending along the first direction, so that a part of the first fixing member 200 can be rotated to be opposite to the first receiving groove 110 in the first direction, so that the first fixing member 200 is located on the upper side of the circuit board 130, thereby fixing the circuit board 130. When the fixation needs to be released, the first fixing member 200 is rotated so that the first fixing member 200 and the first receiving groove 110 are offset in the first direction to release the interference. Specifically, the first fixing member 200 and the first carrier 100 can be connected by a rotating shaft to achieve rotation.

[0046] Alternatively, in other embodiments, the first fixing member 200 is slidably connected to the first carrier 100, and the first fixing member 200 can move relative to the first carrier 100 in a direction perpendicular to the first direction, and through relative sliding, the first fixing member 200 can also be opposite to or staggered with the first accommodating groove 110 in the first direction. Specifically, the first fixing member 200 and the first carrier 100 can be slidably connected through the cooperation of the sliding groove and the sliding table.

[0047] Reference Figure 1 In some embodiments, the fixture further includes a stopper 400, which is fixed to the first carrier 100, one of the stopper 400 and the second fixing member 300 is provided with a plug-in slot 312, and the other is provided with a plug-in portion 410, which is plugged into the plug-in slot 312. The connection between the stopper 400 and the second fixing member 300 can be achieved through the cooperation of the plug-in portion 410 and the plug-in slot 312, and the stopper 400 can provide positioning and limiting, ensure the relative position of the second fixing member 300 and the first carrier 100, ensure that the abutting portion 320 can accurately abut the element 140, and keep the second fixing member 300 at a set position. Specifically, the same end of the second fixing member 300 can be limited by a plurality of stoppers 400, for example, the same end of the second fixing member 300 is provided with stoppers 400 on both sides in the front-rear direction. Alternatively, the limiting member 400 can be set in the form of a seat, and a groove is set on the limiting member 400 to form a concave shape. The end of the second fixing member 300 can be directly embedded in the groove to realize a semi-enclosed structure of the end of the second fixing member 300 by a single limiting member 400.

[0048] Reference Figure 1 , Figure 4 and Figure 5 In some embodiments, the second fixing member 300 extends along a second direction perpendicular to the first direction, and the second fixing member 300 has connecting portions 311 at both ends in the second direction, and the connecting portions 311 are detachably connected to the first carrier 100. The connecting portions 311 at both ends can ensure the stability of the position of the second fixing member 300 through two-point positioning, and the second fixing member 300 is equivalent to spanning the first accommodating groove 110 along the second direction. The second fixing member 300 can be provided with a plurality of abutting portions 320 to fix a plurality of components respectively.

[0049] Reference Figure 1 , Figure 4 and Figure 5 In some embodiments, the second fixing member 300 includes a main body 310, a connecting portion 311 is disposed on the main body 310, a supporting portion 320 is connected to the main body 310, and at least a portion of the supporting portion 320 protrudes from the main body 310 in a third direction, and both the first direction and the second direction are perpendicular to the third direction. The protruding supporting portion 320 can provide a wider field of view, reduce the field of view obstruction of the main body 310, and facilitate the staff to observe the supporting condition of the supporting portion 320 against the component 140, and determine whether the component 140 is accurately in place, so as to ensure the mutual positioning of the circuit board 130 and the component 140.

[0050] Reference Figure 1 , Figure 4 and Figure 5 In some embodiments, the jig further includes a shielding member 500, which is connected to the first carrier 100 or the second fixing member 300. The shielding member 500 extends around the abutting portion 320 and defines an exposure hole 510. At least a portion of the abutting portion 320 is located in the exposure hole 510. The shielding member 500 is used for shielding, which can prevent tin beads from splashing during welding, ensure the product yield of the circuit board 130, and improve welding safety. Specifically, the shielding member 500 can be detachably connected to the first carrier 100 or the second fixing member 300 to ensure that the shielding member 500 is fixed in position. Alternatively, the shielding member 500 can also be placed only on the first carrier 100 to facilitate removal after welding is completed.

[0051] Reference Figure 5 In some embodiments, one of the shielding member 500 and the second fixing member 300 is provided with a positioning groove 313, and the other is provided with a positioning portion 520, and the positioning portion 520 is inserted into the positioning groove 313. Through the cooperation of the positioning portion 520 and the positioning groove 313, the shielding member 500 can be provided with a limit, the probability of the shielding member 500 slipping is reduced, and the mutual positioning of the shielding member 500 and the second positioning member is ensured, so that the element 140 is conveniently located exactly in the exposure hole 510.

[0052] Reference Figures 1 to 4In some embodiments, the positioning hole 120 passes through the first carrier 100 along the first direction, and the fixture further includes a cover seal 600, which is detachably connected to the first carrier 100, and is located on a side of the first carrier 100 away from the second fixing member 300, and the cover seal 600 covers the positioning hole 120. The positioning hole 120 that passes through the first carrier 100 allows the component 140 to be assembled from the side of the first carrier 100 away from the second fixing member 300, so as to facilitate assembly and positioning. The cover seal 600 can cover the positioning hole 120 after the assembly is completed, so as to avoid the possibility of the component 140 accidentally detaching from the positioning hole 120. For example, in the embodiment where the component 140 is selected as an NTC (thermosensitive ceramic component), the component 140 has a pin and a body. The body is relatively large and usually cannot pass through the through hole reserved in the circuit board 130. Therefore, only the pin needs to pass through the positioning hole 120 and the through hole of the circuit board 130, and a part of the pin is exposed on the upper surface of the circuit board 130 for welding. The through positioning hole 120 can also meet the assembly of the component 140 in this case. On the other hand, when assembling the component 140 from the bottom side of the first carrier 100, it is usually necessary to flip the first carrier 100. The fixing of the circuit board 130 by the first fixing member 200 can also prevent the circuit board 130 from being separated from the first accommodating groove 110.

[0053] Reference Figure 1 and Figure 6 In some embodiments, the fixture further includes a second carrier plate 700, the second carrier plate 700 includes a limiting portion 710 and a sliding portion 720, the sliding portion 720 can move relative to the limiting portion 710 and is relatively fixed, and a second accommodating groove 730 is defined between the sliding portion 720 and the limiting portion 710, and the second accommodating groove 730 is used to accommodate the first carrier plate 100. The second carrier plate 700 can further improve the stability of the fixture by carrying the first carrier plate 100, and by changing the position of the sliding portion 720 relative to the limiting portion 710, the first carrier plates 100 of different sizes can be adapted to facilitate the processing of different circuit boards 130. Specifically, the second carrier plate 700 includes a plate body 750, and the sliding part 720 can be relatively fixed to the plate body 750 by magnetic attraction to maintain relative fixation with the limiting part 710, or the sliding part 720 can also be pre-tightened by bolts or other pre-tightening parts to achieve detachable fixation on the plate body 750 to maintain relative fixation with the limiting part 710.

[0054] Reference Figure 3 and Figure 6In some embodiments, the first carrier 100 is provided with a first magnetic member 150, and the second carrier 700 is provided with a second magnetic member 740. The first magnetic member 150 and the second magnetic member 740 can be mutually adsorbed. The adsorption of the first magnetic member 150 and the second magnetic member 740 can reduce the probability of the first carrier 100 being separated from the second carrier 700. The first magnetic member 150 and the second magnetic member 740 are adsorbed when they correspond to each other, which can play a positioning effect, ensure the relative positioning of the first carrier 100 on the second carrier 700, and ensure the overall positioning of the welding. When the first carrier 100 is turned over, the adsorption force of the first magnetic member 150 and the second magnetic member 740 can play a role similar to a rotating shaft, so that the first carrier 100 is turned around the axis, which is convenient for assembling the component 140 and the circuit board 130. The first carrier 100 can also be provided with a handle 160 for easy grasping. The handle 160 is located on the opposite side of the first carrier 100 relative to the first magnetic member 150 to facilitate the turning operation.

[0055] Reference Figure 7 In some embodiments, the fixture may also be provided with a motion platform 800, and the second carrier plate 700 is connected to the motion end of the motion platform 800. The motion platform 800 may be selected as a unidirectional motion platform, a bidirectional motion platform or a three-directional motion platform, such as an x-axis motion platform, an xy-axis motion platform or an xyz-axis motion platform, to facilitate coarse positioning or operation between different workstations.

[0056] Reference Figure 1 , Figure 4 and Figure 7 According to the welding system of the embodiment of the present application, it includes a welding device (not shown in the figure) and a jig of any of the above embodiments, and the welding device is used to weld the circuit board 130 and the component 140 carried by the jig. The jig of the embodiment of the present application can improve the positioning accuracy and positioning stability of the circuit board 130 and the component 140, ensure the welding effect, reduce the probability of multiple welding at the same position, and reduce the probability of fracture at the welding position.

[0057] The welding device can be specifically selected as a hot pressure welding device to ensure the welding effect of the circuit board 130. The embodiments of the present application are described in detail above in conjunction with the drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
