Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a limiting mechanism for an ultrasonic welding socket. Background Technology

[0002] Single-cell batteries typically use tab foil to connect the terminals and tabs, achieving electrical connection between the core and the battery casing. After pre-welding, the tab foil is moved to the main welding station and superimposed on the metal tabs. The main welding head and welding seat move towards each other, pressing the tabs together for ultrasonic welding. Ultrasonic welding is a technique that uses high-frequency vibration under static pressure to cause friction between two objects, resulting in molecular fusion. One side of the tab is connected to the tab foil, and the other side faces the ultrasonic welding head. The ultrasonic welding head has welding teeth that act on the tab, forming weld points. The tab and tab foil are connected at these weld points. During the welding process, the welding teeth of the welding seat, under pressure and with relative movement, inevitably suffer damage due to friction. Furthermore, the welding teeth are generally small in size and have sharp tips. After welding a certain number of cells, the same welding seat can no longer handle efficient welding work and needs to be replaced to prevent weld cracks and incomplete welds.

[0003] The current method for replacing the main welding socket involves placing the socket in its approximate position, pre-fixing it with the locking screws, then using a blank metal tab to test the pressure and visually confirming the relative position of the welding head teeth and the welding socket teeth. If the relative position of the welding teeth does not meet the requirements, the screws need to be loosened again, the socket's front-to-back and left-to-right positions adjusted, and the process repeated. Because the main welding socket is replaced frequently, and the position is manually calibrated repeatedly each time, unplanned downtime on the production line increases, severely impacting uptime and output.

[0006] In one embodiment, the ultrasonic welding base has connecting blocks on its two opposite outer sides. The connecting blocks are integrally formed with the ultrasonic welding base. The connecting blocks on both sides of the ultrasonic welding base are provided with first strip grooves for screws or bolts to pass through.

[0007] In one embodiment, a fixing block is provided on each of the two opposite outer sides of the vacuum limiting block. The fixing block is integrally formed with the vacuum limiting block.

[0017] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0018] A limiting mechanism for an ultrasonic welding socket, as described in the following figure. Figure 1 and Figure 2The system includes an ultrasonic welding base 10 and a vacuum limiting block 20 disposed on one side of the ultrasonic welding base 10. One side of the vacuum limiting block 20 abuts against the ultrasonic welding base 10 to limit the movement of the ultrasonic welding base 10 in the direction of approaching or moving away from the vacuum limiting block 20. A movable limiting block 30 is provided on the vacuum limiting block 20. One side of the movable limiting block 30 abuts against one side of both the ultrasonic welding base 10 and the vacuum limiting block 20. The movable limiting block 30 is used to facilitate adjustment of the position of the ultrasonic welding base 10, ensuring that the relative position of the ultrasonic welding head and the ultrasonic welding base 10 remains unchanged when using different ultrasonic welding heads. It should be noted that the upper end face of the ultrasonic welding base 10 is provided with fine and sharp welding teeth, and the lower end face of the ultrasonic welding head, which is positioned opposite the ultrasonic welding base 10, is also provided with welding teeth. This ensures that when the electrode foil and electrode are compacted, the electrode foil and electrode remain stationary relative to the ultrasonic welding head during the ultrasonic welding process, thereby maximizing the utilization of the welding energy. When changing different ultrasonic welding heads, the ultrasonic welding base 10 needs to be adjusted in position simultaneously. The position of the ultrasonic welding base 10 is fixed by setting a vacuum limit block 20, and the position of the ultrasonic welding base 10 is finely adjusted and limited by a movable limit block 30, so as to flexibly adjust the position of the ultrasonic welding base 10 so that the relative position of the ultrasonic welding head and the ultrasonic welding base 10 remains unchanged.

[0019] Furthermore, referring to Figure 1 and Figure 2 The ultrasonic welding base 10 has connecting blocks 11 on both opposite outer sides. The connecting blocks 11 are integrally formed with the ultrasonic welding base 10 and are used to fix the ultrasonic welding base 10 to the ultrasonic welding equipment. The connecting blocks 11 on both sides of the ultrasonic welding base 10 are provided with first strip grooves 111. The connecting blocks 11 are fixed to the ultrasonic welding equipment by screws or bolts passing through the first strip grooves 111.

[0020] Furthermore, referring to Figure 1 and Figure 2 The vacuum limiting block 20 has two fixing blocks on its two opposite outer sides. The fixing blocks are integrally formed with the vacuum limiting block 20. The positions of the two fixing blocks correspond to the positions of the two connecting blocks 11, and the two fixing blocks abut against one side of the two connecting blocks 11. The fixing blocks are used to fix the movable limiting block 30 and to fix the vacuum limiting block 20 to the ultrasonic welding equipment.

[0021] Furthermore, referring to Figure 1 and Figure 2 The length of the vacuum limiting block 20 is adapted to the length of the ultrasonic welding base 10, and the length of the fixing block is longer than the length of the connecting block 11, so that when the ultrasonic welding base 10 moves along the length direction of the vacuum limiting block 20, it abuts against one side of the vacuum limiting block 20 and the fixing block to achieve linear movement without deviation.

[0022] Reference Figure 1 and Figure 2 The system comprises two fixing blocks, a first fixing block 21 and a second fixing block 22. The first fixing block 21 has a second slot 211 for screws or bolts to pass through, thus fixing the vacuum limiting block 20 to the ultrasonic welding equipment. A movable limiting block 30 is mounted on the second fixing block 22, which has a third slot 221. The movable limiting block 30 also has a fourth slot 31, corresponding to the third slot 221, for screws or bolts to pass through. Screws or bolts are sequentially passed through the fourth slot 31, the third slot 221, and the ultrasonic welding equipment to fix the movable limiting block 30 to the vacuum limiting block 20 and vice versa.

[0023] Furthermore, referring to Figure 1 The movable limiting block 30 is L-shaped and includes a limiting part 32 and a fixing part 33, which are integrally formed. The fixing part 33 is arranged along the length direction of the second fixing block 22, and the length of the fixing part 33 is adapted to the length of the second fixing block 22. The fixing part 33 is located on the second fixing block 22. A fourth strip groove 31 passes through the fixing part 33 to fix the fixing part 33 to the vacuum limiting block 20. The limiting part 32 is perpendicular to the fixing part 33 and is located above the second fixing block 22 and the limiting block that abuts against the second fixing block 22. One side of the limiting part 32 abuts against the side of the ultrasonic welding base 10, and the limiting part 32 is used to adjust the position of the ultrasonic welding base 10. The movable limiting block 30 can slide along the length of the second fixed block 22. When the position of the ultrasonic welding head shifts relative to the other, the position of the movable limiting block 30 can be adjusted so that the ultrasonic welding base 10 can be adjusted to a suitable position along with the movable limiting block 30, so as to ensure that the relative position of the ultrasonic welding head and the ultrasonic welding base 10 remains unchanged.

[0024] Furthermore, referring to Figure 1 and Figure 2 The first strip groove 111, the second strip groove 211, the third strip groove 221, and the fourth strip groove 31 have the same length, and the adjustable length of the first strip groove 111, the second strip groove 211, the third strip groove 221, and the fourth strip groove 31 is greater than the center distance between two adjacent welding teeth on the ultrasonic welding base 10. Thus, the adjustment space of the ultrasonic welding base 10 and the movable limiting block 30 is greater than the center distance between two adjacent welding teeth on the ultrasonic welding base 10, resulting in a large adjustable range for the ultrasonic welding base 10, and ensuring that the relative position of the ultrasonic welding head and the ultrasonic welding base 10 remains unchanged when adjusting the position of the ultrasonic welding base 10.

[0025] In one embodiment, the movable limiting block 30 is located between the outer side of the connecting block 11 of the ultrasonic welding base 10 and the side of the second fixing block 22 facing the ultrasonic welding base 10. The limiting part 32 of the movable limiting block 30 abuts against the outer side of the connecting block 11 of the ultrasonic welding base 10 located on the side of the second fixing block 22, and the fixing part 33 of the movable limiting block 30 abuts against the side of the second fixing block 22 facing the ultrasonic welding base 10. A fourth strip groove 31 passing through the fixing part 33 is located on the side of the fixing part 33, so that bolts or screws can pass through to fix the fixing part 33 to the second fixing block 22.

[0026] Furthermore, referring to Figure 1 and Figure 2 The vacuum limiting block 20 is equipped with a vacuum adsorption component 40, which is used to adsorb the metal electrode tabs to reduce the risk of the metal electrode tabs moving relative to the ultrasonic welding base 10. The vacuum adsorption component 40 includes a vacuum suction nozzle 41 and a vacuum generator. The vacuum limiting block has multiple openings 42 for placing the vacuum suction nozzle 41. One end of the vacuum suction nozzle 41 is connected to the vacuum generator. By controlling the vacuum generator, the vacuum suction nozzle 41 adsorbs the metal electrode tabs above it, thereby fixing the metal electrode tabs.

[0027] By employing vacuum limiting blocks 20 and movable limiting blocks 30 to limit the displacement of the ultrasonic welding socket 10 in four directions, the consistency of the welding state is effectively achieved under the same conditions each time. This greatly reduces the time required to replace the ultrasonic welding socket 10 while ensuring consistent cell welding quality. The movable limiting block 30 effectively addresses the inability to flexibly adjust the vacuum limiting blocks 20 and movable limiting blocks 30 to the standard state when the ultrasonic welding head experiences relative displacement, maximizing the controllable space and adaptability. When using different ultrasonic welding heads, the position of the movable limiting block 30 can be flexibly adjusted to maintain the relative position of the ultrasonic welding head and the ultrasonic welding socket 10, ensuring the stability of the cell welding quality.

[0028] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
