[0036] Embodiment

[0037] In a battery structure, tabs are provided on a battery core. The tabs need to be welded to connection pieces and connected to the battery terminals through the connection pieces. The welding stability between the connection pieces and the tabs is directly related to the safety performance of the battery.

[0038] In the present application, an ultrasonic welding tooling is used to position a first workpiece 500 and a second workpiece, and press the positioned first workpiece 500 and the second workpiece, facilitating subsequent welding of the two together. The first workpiece 500 includes but is not limited to an electric core, and the electric core is configured with a tab 501. The second workpiece includes but is not limited to a connecting piece, and the second workpiece is used to weld with the tab 501 of the electric core.

[0039] As Figures 1-4 shown, in a first aspect, an embodiment of the present application provides an ultrasonic welding tooling, including: a jig 100 configured with a positioning surface, and a partial structure of the positioning surface is recessed to form a positioning groove, and the positioning groove is configured to accommodate the first workpiece 500 and the second workpiece; a pressing plate 200 disposed on the positioning surface for pressing the second workpiece against the first workpiece 500.

[0040] Exemplarily, the positioning groove includes a first groove 101 and a second groove 102. The first groove 101 is configured to accommodate the first workpiece 500, and the second groove 102 is used to accommodate the second workpiece. There are two second grooves 102, and when the jig 100 is distributed in the left - right direction, one of the second grooves 102 is located on the left side of the first groove 101, and the other second groove 102 is located on the right side of the first groove 101.

[0041] It can be understood that the pressing plate 200 is located near the welding position of the first workpiece 500 and the second workpiece. For example, when there are two second workpieces, correspondingly there are also two pressing plates 200. At the same time, the position of the jig 100 corresponding to the pressing plate 200 can be recessed, and this recessed position is used to adapt to the pressing plate 200.

[0042] In the above implementation process, the positioning surface of the jig 100 is configured with a positioning groove, and the first workpiece 500 and the second workpiece are placed in the positioning groove for positioning before welding the first workpiece 500 and the second workpiece. Subsequently, the pressing plate 200 presses the first workpiece 500 and the second workpiece together, facilitating subsequent welding of the first workpiece 500 and the second workpiece together. The entire process can ensure the positioning before and after the weld mark, ensure accurate and convenient positioning, and ensure welding stability.

[0043] As Figure 2As shown, the pressing plate 200 is made of a metal material. For example, the pressing plate 200 is made of iron. An adsorbent 103 is arranged on the side of the fixture 100 away from the positioning surface. The fixture 100 is made of, but not limited to, stainless steel (non-ferromagnetic). The adsorbent 103 includes, but is not limited to, a magnet. The adsorbent 103 is used to adsorb the pressing plate 200 to the fixture 100.

[0044] In the above implementation process, after the pressing plate 200 is adsorbed by the adsorbent 103, it can press the first workpiece 500 and the second workpiece together, ensuring the positioning before and after welding, ensuring accurate and convenient positioning, and ensuring welding stability.

[0045] In some embodiments, the cross-sectional dimension of the pressing plate 200 is not less than the cross-sectional dimension of the second workpiece. This is beneficial for pressing the first workpiece 500 and the second workpiece together, ensuring the positioning before and after welding, ensuring accurate and convenient positioning, and ensuring welding stability.

[0046] As Figures 1-2 shown, an avoidance opening 105 is arranged on the outer edge of the fixture 100. The avoidance opening 105 is recessed along the direction close to the inner cavity of the fixture 100. Exemplarily, the avoidance opening 105 includes, but is not limited to, a U shape, and two avoidance openings 105 can be arranged. The two avoidance openings 105 are symmetrically distributed. One of the avoidance openings 105 is located on the front side of the fixture 100, and the other avoidance opening 105 is located on the rear side of the fixture 100.

[0047] In the above implementation process, the avoidance opening 105 is arranged on the fixture 100. Through this avoidance opening 105, it is convenient for the user to pick up and place the first workpiece 500 and / or the second workpiece, avoiding damage to the first workpiece 500 or the second workpiece and improving safety.

[0048] In some embodiments, the avoidance opening 105 corresponds to the first workpiece 500 for picking up and placing the first workpiece 500. It can realize convenient and safe picking up and placing of the first workpiece 500 and avoid damage to the first workpiece 500 during picking up and placing.

[0049] In some embodiments, the ultrasonic welding tooling further includes a welding base 300, and the welding base 300 is arranged on the side of the fixture 100 away from the positioning surface.

[0050] In the above implementation process, the welding base 300 is arranged on one side of the fixture 100. It can not only provide support for the fixture 100, but also accurately position the fixture 100, facilitating subsequent welding of the first workpiece 500 and the second workpiece and ensuring welding stability.

[0051] In some embodiments, the fixture 100 is configured with a placement groove 104, and the placement groove 104 is configured to accommodate at least a part of the structure of the solder socket 300. For example, the width of the placement groove 104 is consistent with the width of the solder socket 300, and the length of the placement groove 104 is greater than the length of the solder socket 300, etc.

[0052] In the above implementation process, the fixture 100 can be quickly positioned with the solder socket 300 through the placement groove 104, which has the advantages of accurate and convenient positioning, and ensures the stability of welding.

[0053] In some embodiments, the ultrasonic welding tooling further includes a support base 400, and the support base 400 is located on the side of the fixture 100 close to the solder socket 300; Exemplarily, the support base 400 and the solder socket 300 are spaced apart at the lower end of the fixture 100 to support the fixture 100 respectively.

[0054] In some embodiments, a scale line 401 is configured on the side of the support base 400 close to the fixture 100. For example, the scale line 401 is distributed in the front-rear direction.

[0055] In the above implementation process, the fixture 100 can be supported not only by the support base 400 and the solder socket 300, but also the scale line 401 on the support base 400 can be used to calibrate the position of the fixture 100 to realize the positioning of the fixture 100, which is beneficial to adjusting the position of the welding mark.

[0056] In a second aspect, the present application also provides a welding machine, including: a welding device 600, which is configured with a welding head 601, and the welding device 600 includes but is not limited to an ultrasonic welding device 600; and the ultrasonic welding tooling as described above, and the ultrasonic welding tooling is located below the welding head 601.

[0057] In the above implementation process, the welding head 601 of the welding device 600 is located above the ultrasonic welding tooling, and is used to weld the first workpiece 500 and the second workpiece together. Since the welding machine provided in the second aspect includes the ultrasonic welding tooling, the welding machine has all the technical effects of the ultrasonic welding tooling, which will not be elaborated here.

[0058] In all embodiments of the present application, "big", "small" are relative, "many", "few" are relative, "up", "down" are relative, and the present application embodiments will not elaborate on the expression methods of such relative terms.
