The battery confluence piece welding tool is provided with a supporting component 10 and a pressing component 20, when a movable part 220 of the pressing component 20 can be located at an opening position relative to a fixed plate 210, a target battery 40 can be placed on a supporting part 111 of the supporting component 10, and the target battery 40 is fixed and positioned through the supporting component 10; then, the movable member 220 is located at the compressing position relative to the fixed plate 210, so that the compressing plates 230 compress the bus bar 50 on the pole of the target battery 40, the target battery 40 and the bus bar 50 are fixed during welding, manual assistance is not needed during welding, the situation that the personal safety is influenced by mistakenly touching laser by operators during welding is avoided, and the testing efficiency is improved.

In an embodiment of the present application, as shown in fig. 1 and fig. 2, the welding tool further includes: the base 30, the supporting component 10 and the pressing component 20 are arranged on the base 30. Through locating supporting component 10 and compress tightly subassembly 20 on base 30 for the welding frock is connected and is formed overall structure, and base 30 provides stable supporting role for the welding frock, improves the welding frock and appears rocking the condition of surely inclining easily, is convenient for the transport of welding frock simultaneously.

The base 30 may be a metal plate, for example, rectangular, and the corners may be chamfered. The supporting member 10 and the pressing member 20 may be disposed on the base 30 by welding, bolting, etc. Wherein, can set up the through-hole on the base 30 to the cooperation bolt is fixed base 30 on workstation or bottom surface, in order to realize fixing to welding frock. For example, when the base 30 is a rectangular plate, a through hole may be formed at each of four corners for the screw to pass through. Of course, the base 30 may also be in the shape of a circle, a trapezoid, a triangle, or an irregular shape, the base 30 may be a metal plate or a composite plate, and the number of the through holes on the base 30 may be two, three, five, or more, which is not limited in this application.

In one embodiment of the present application, as shown in fig. 8-10, the support assembly 10 includes a support base 110. The support base 110 is formed with an accommodating space having an open end, the accommodating space forming a support portion 111 in which the bottom of the target battery 40 is placed, thereby forming a fixing of the target battery 40.

In this case, when the target battery 40 is a cylindrical battery, the accommodating space is also a circular hole with a matching diameter, so as to improve the stability of the target battery 40 in the supporting portion 111. Wherein the depth of the receiving space is smaller than the height of the target battery 40 so that the pole of the target battery 40 can protrude from the opening of the receiving space. For example, the depth of the accommodation space is one quarter, one third, one half, and so on of the height of the target battery 40. In addition, through the degree of depth that sets up accommodation space, can make supporting seat 110 match the battery of fixed co-altitude not, improved welding frock's suitability.

The supporting base 110 can be fixedly connected to the base 30 by welding, bonding, or bolting.

In one embodiment of the present application, as shown in fig. 11-13, the support assembly 10 further comprises: the tightening ring 120 is sleeved on the support base 110. As shown in fig. 8 to 10, at least a portion of the outer side wall of the support seat 110 from the open end toward the other end is a slope, and at least one slit 112 extending from the open end toward the other end is formed on the support seat 110. The tightening ring 120 is sleeved on the inclined plane of the support base 110, and the size of the opening end can be adjusted by adjusting the position of the tightening ring 120 on the inclined plane.

When the tightening ring 120 moves toward the bottom of the support base 110, since the outer diameter of the side wall of the support base 110 gradually increases, the side wall of the support base 110 is contracted inward, so that the diameter of the accommodation space gradually decreases, thereby fastening the target battery 40 in the accommodation space; when the tightening ring 120 moves toward the top of the support seat 110, since the outer diameter of the support seat 110 is gradually reduced, the side wall of the support seat 110 is outwardly diffused, so that the diameter of the accommodating space is gradually increased, a gap is formed between the target battery 40 and the side wall of the accommodating space, and the target battery 40 after welding can be taken out. In addition, through set up the straining ring 120 on the inclined plane of supporting seat 110, can make supporting seat 110 match the battery of fixed different diameters, improved the suitability of welding frock.

The inner wall of the tightening ring 120 may also be an inclined surface, and the tangential angle between the inner wall of the tightening ring 120 and the inclined surface of the support base 110 is complementary, i.e. the inclined surface of the tightening ring 120 is parallel to the inclined surface of the support base 110. By also beveling the inner wall of the tightening ring 120. The contact area of the tightening ring 120 with the inclined surface of the support base 110 is increased, so that a more stable tightening force can be applied to the support base 110 by the tightening ring 120 to improve the reliability of fixing the target battery 40.

As shown in fig. 8 and 9, the inclined surface of the support base 110 may extend from the top to the bottom side. For example, the slope may account for 50%, 70%, or 100% of the height of the support seat 110 in the height direction of the support seat 110.

In which the cutouts 112 in the support base 110 extend from the top to the bottom side as shown in figures 8 and 9. For example, the gap 112 may occupy 50%, 70% or 100% of the height of the support seat 110 in the height direction of the support seat 110 (i.e., the gap 112 penetrates through the support seat 110 in the height direction).

As shown in fig. 8 to 10, three notches 112 are provided on the support seat 110, and the three notches 112 are distributed at an included angle of 120 ° in the circumferential direction of the support seat 110, so that when the tightening ring 120 is tightened, the inward deformation can be more easily performed, thereby clamping the target battery 40.

Certainly, one, two, four or more notches can be arranged on the supporting seat 110, the length of each notch extending from the top to the bottom can be the same or different, the width of each notch can be the same or different, and the present application does not limit this; all be through the width, length, shape, quantity etc. of transform opening in order to realize tightening up through the straining ring and to make the inside shrink of lateral wall of supporting seat make accommodation space's diameter reduce's technical scheme, all belong to the scope of protection of this application.

In an embodiment of the present application, the movable member 220 is slidably connected to the fixed plate 210, and the movable member 220 can be located at a pressing position close to the supporting portion 111 and an opening position far from the supporting portion 111 by sliding relative to the fixed plate 210.
