In the related art, the pressing plate 310 is not easy to adjust the degree of pressing the workpiece 102, the required precision is high, when the degree of pressing is too high, the pressing plate 310 excessively presses the workpiece 102 to be welded, which causes deformation of the workpiece 102 to be welded or damage of the cylindrical battery 101, and when the degree of pressing is too low, the workpiece 102 to be welded and the cylindrical battery 101 cannot be effectively contacted, which causes poor welding such as cold welding in a welding area.

Further, the elastic part 220 is slidably connected with the fixing part 210 along the vertical direction, so as to provide a guide for lifting the elastic part 220; alternatively, the groove wall of the clamping groove 111 contacts with the outer surface of the elastic part 220, and the elastic part 220 is guided by the groove wall of the clamping groove 111 during the lifting process, so that the lifting of the elastic part 220 is more stable.

Since the cylindrical battery 101 is positioned at the bottom of the pressing plate 310 in the vertical direction and is always in contact with the pressing plate 310 by the abutting action of the elastic portion 220, the cylindrical battery 101 has high positional accuracy.

It should be noted that, the pressing plate 310 may be always in a static state, the height of the pressing plate 310 is determined in advance, and the cylindrical battery 101 and the workpiece 102 to be welded are raised to a certain height and then contact with the pressing plate 310, and are covered by the pressing plate 310; alternatively, the pressing plate 310 can be lifted in the vertical direction, the lowering distance of the pressing plate 310 is preset, and when the pressing plate 310 is lowered by the preset distance, the workpiece 102 to be welded is pressed and covered, so that the workpiece 102 to be welded and the cylindrical battery 101 are clamped between the elastic part 220 and the pressing plate 310.

Specifically, referring to fig. 5, the pressing plate 310 can be lifted in a vertical direction to press the top of the workpiece 102 to be welded, the pressing assembly 300 includes a first pressing portion 312 and a second pressing portion 313, the first pressing portion 312 is connected to the top of the first clamping member 110, the second pressing portion 313 is connected to the top of the second clamping member 120, the first pressing portion 312 is at least provided with a first pressing groove 3122 along the vertical direction, the second pressing portion 313 is at least provided with a second pressing groove 3132 along the vertical direction, and the first pressing groove 3122 and the second pressing groove 3132 located at the same height are used for limiting the workpiece 102 to be welded. Thus, when the first clamping member 110 and the second clamping member 120 approach each other and clamp the cylindrical battery 101, the first pressing groove 3122 and the second pressing groove 3132 combine with each other and define a space for limiting the member to be welded 102 in the radial direction, ensuring the positional accuracy of the member to be welded 102 and the cylindrical battery 101 in the horizontal direction; and, when the pressing plate 310 moves downward and presses over the top of the member to be welded 102, the member to be welded 102 is in close contact with the cylindrical battery 101 in the vertical direction, improving the welding effect of the cylindrical battery 101 and the member to be welded 102.

In addition, since the pressing part protrudes with respect to the bottom of the pressing plate 310, the pressing part can be inserted into the first and second pressing grooves 3122 and 3132 and contact the top of the workpiece 102 to be welded, so that the pressing plate 310 presses the workpiece 102 to be welded more stably.
In other embodiments, the bottom of the pressing plate 310 is recessed to form a limiting groove, and the limiting groove is used to accommodate part of the piece to be welded 102 and limit the edge of the piece to be welded 102. The shape of the limiting groove is matched with the shape of the piece to be welded 102, and after the piece to be welded 102 is inserted into the limiting groove, the piece to be welded is limited by the limiting groove and is accurately limited in the horizontal direction. It should be noted that, the press cover assembly 300 includes a driving component for driving the first clamping member 110 and the second clamping member 120 to move toward or away from each other, and a driving component for driving the pressing plate 310 to lift, where the driving component may be configured as an elbow clamp, an air cylinder, a ball screw assembly, etc.; in order to enable the pressing plate 310 to be applicable to unused workpieces 102 to be welded and limit different workpieces 102 to be welded, the pressing plate 310 is detachably mounted on a driving component, and when a certain workpiece 102 to be welded is required to be limited, the corresponding pressing plate 310 is replaced to the driving component, so that the welding jig has higher practicability.
It should be noted that, in the case that the to-be-welded pieces 102 are stacked in the vertical direction, the pressing portion may be provided with the pressing groove and the pressing step at the same time, so as to radially limit the corresponding to-be-welded pieces 102 at different heights. Specifically, as shown in fig. 3, the pressing plate 310 includes a first pressing portion 312 and a second pressing portion 313, the first pressing portion 312 is connected to the top of the first clamping member 110, the second pressing portion 313 is connected to the top of the second clamping member 120, the first pressing portion 312 is at least vertically provided with a first pressing step 3121 and at least vertically provided with a first pressing groove 3122, the second pressing portion 313 is at least vertically provided with a first pressing step 3121 and at least vertically provided with a second pressing groove 3132, the first pressing step 3121 and the second pressing step 3131 at the same height are used for pressing edges of the workpiece 102 to be welded, and the first pressing step 3122 and the second pressing groove 3132 at the same height are used for limiting the workpiece 102 to be welded in the radial direction.
For example, if two pieces to be welded 102 are stacked in the vertical direction, the upper one is positioned as a, the lower one is defined as B, the first pressing portion 312 is provided with two first pressing grooves 3122 and one first pressing step 3121, the first pressing step 3121 is located above the first pressing groove 3122, the second pressing portion 313 is also provided with two second pressing grooves 3132 and one second pressing step 3131, the second pressing step 3131 is located above the second pressing groove 3132, the heights of the two first pressing grooves 3122 and the two second pressing grooves 3132 are consistent, the lower first pressing groove 3122 and the second pressing groove 3132 radially limit B, the lower first pressing groove 3122 and the second pressing groove 3132 radially limit a, the first pressing step 3121 and the second pressing step 3131 press the top of a, and the battery a and the top of B are covered on the top of the cylinder to be welded 101, and the vertical sides of the cylinder to be welded are realized.
The utility model also provides a cylindrical battery welding device, which comprises the cylindrical battery welding jig and a welding head, wherein laser emitted by the welding head can pass through the notch 311 and irradiate a welding area, and the to-be-welded piece 102 and the cylindrical battery 101 are welded. Because the elastic part 220 which can elastically lift is arranged in the cylindrical battery welding device, the part 102 to be welded and the cylindrical battery 101 are stably covered by the stable pressing plate 310 and the elastic part 220, the adjustment difficulty of the covering degree of the pressing plate 310 is reduced, and the positioning precision and the welding quality of the cylindrical battery 101 are improved.
The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model. Furthermore, embodiments of the utility model and features of the embodiments may be combined with each other without conflict.
