Description

Technical Field

[0001] The invention relates to the technical field of battery tab welding, in particular to a battery tab welding and shaping device. Background Art

[0002] Battery tabs are an important component of the battery. They are the connection points between the internal electrodes (positive and negative) of the battery and the external circuit. The design and manufacture of the tabs are crucial to the performance, safety and service life of the battery. After production, the battery tabs are mostly welded to the cell ends of the combined battery by laser welding.

[0003] At present, when performing the tab welding operation at the end of the battery cell, the current operation process has many inconveniences and safety hazards. The tab loading process is mostly completed manually, and the operator needs to place the tabs one by one to the designated position. This process not only requires a high degree of concentration, but also the operation is highly repetitive, which can easily cause workers to feel tired, which may lead to problems such as inaccurate loading position or low efficiency. In addition, after the tab is placed, it is necessary to manually press the middle of the tab. This action seems simple, but it actually contains great risks. Because the tabs are usually small and made of special materials, the tabs are often difficult to load and cannot be welded. In particular, during the pressing process, if improper force is used, the tab may be deformed or damaged, which will affect the subsequent welding quality, resulting in loose welding or serious defects such as cold welding, reducing the performance and safety of the battery. Moreover, the manual pressing operation is close to the welding area, and workers are easily exposed to the high temperature, strong light and possible splashes generated by the welding equipment. Once the protective measures are slightly negligent, it is very likely to cause accidental injuries such as burns and eye injuries, posing a serious threat to the personal safety of the operator. For this reason, we propose a battery tab welding and shaping device. Summary of the invention

The inner wall of the guide groove is smooth, and the friction force is small, which can ensure the smooth sliding of the pole ear. There are two movable guide parts 52. The two movable guide parts 52 are movably arranged on both sides of the end of the fixed guide part 51, and a baffle 521 is fixed at the lower end of the inner part of the movable guide part 52. The baffle 521 is used to block the pole ear sliding to the movable guide part 52 to prevent the pole ear from detaching. The lower end surface of the movable guide part 52 is hard, smooth and resistant to high temperature. After welding, the welding point can be pressed down for shaping.

[0046] Secondly, for tabs of different lengths, guide tracks 5 of different sizes can be provided for guiding.

[0047] See also Figure 5 and Figure 6 As shown, the transverse movement structure 61 includes a mounting plate 611 mounted on the upper end surface of the fixed material guide portion 51 near the lower end, a two-way telescopic rod 612 is mounted on the lower end surface of the mounting plate 611, both ends of the two-way telescopic rod 612 are connected to connecting strips 613, and a movable material guide portion 52 is mounted at the bottom end of a connecting strip 613;

[0048] The movable adsorption structure 62 includes a first telescopic rod 621 which is installed through the mounting plate 611. The first telescopic rod 621 is preferably an electric or pneumatic telescopic rod, and a suction cup 622 is installed at the bottom end of the first telescopic rod 621. After the tab is guided to the movable material guide part 52, the suction cup 622 can be used to suck the middle part of the upper end surface of the tab, and then the bidirectional telescopic rod 612 is started, and the two movable material guide parts 52 are synchronously moved outward by the bidirectional telescopic rod 612 to release the supporting effect of the movable material guide part 52, and then the first telescopic rod 621 is used to drive the tab to move downward so that the tab fits on the battery cell of the battery pack to be welded.

[0049] See also Figure 3 As shown, the pushing assembly 7 includes two second telescopic rods 72 installed on both sides of the top of the storage tray 4, preferably electric or pneumatic telescopic rods, the output ends of the two second telescopic rods 72 are commonly connected to a pushing plate 71, the bottom end of the pushing plate 71 contacts the bottom of the tab storage slot 41, the second telescopic rod 72 is started, and the second telescopic rod 72 is used to push the pushing plate 71 to move, so as to push the tab, and a soft pad can be set on the pushing surface of the pushing plate 71 to avoid extrusion damage to the tab.

[0050] See also Figure 4 As shown, the telescopic assembly 8 includes a motor 81 installed on one side of the bottom end of the storage tray 4. The motor 81 is a forward and reverse motor. A lead screw 82 is installed at the output end of the motor 81. A lead screw nut seat is provided outside the lead screw 82. The side wall of the fixed material guide portion 51 is connected to the lead screw nut seat.

[0051] The telescopic assembly 8 also includes protrusions 83 fixed to the two ends of the other side of the bottom end of the material storage tray 4, a guide rod 84 is connected between the two protrusions 83, a slider is slidably provided on the outside of the guide rod 84, and the other side of the fixed material guide part 51 is connected to the slider. When the motor 81 is started, the output end of the motor 81 can be used to drive the lead screw 82 to rotate, and then the lead screw nut seat can be used to drive the fixed material guide part 51 to move, so that the material receiving port at the top of the fixed material guide part 51 is directly opposite to the tab lead-out groove 42 or moves backward.

[0052] Among them, when the screw nut seat drives the fixed material guide part 51 to move, the other side of the fixed material guide part 51 slides smoothly along the guide rod 84 through the slider, effectively avoiding the unstable phenomena such as left and right shaking, deviation or twisting of the fixed material guide part 51 that may occur during the movement. This bilateral coordinated moving mechanism greatly improves the stability of the movement of the fixed material guide part 51.

[0053] See also Figure 8-Figure 10 As shown, the abutment assembly 9 includes a third telescopic rod 91 and a butt plate 92. The third telescopic rod 91 is preferably an electric or pneumatic telescopic rod. A first groove 43 is provided inside the storage tray 4. The first groove 43 is opposite to the pole lug storage groove 41, and the bottom end of the first groove 43 is lower than the bottom end of the pole lug storage groove 41. The third telescopic rod 91 is installed in the first groove 43, and the butt plate 92 is installed at the output end of the third telescopic rod 91. After a pole lug falls into the pole lug lead-out groove 42, the third telescopic rod 91 starts to control the movement of the butt plate 92, and the butt plate 92 is used to press the pole lug in the pole lug storage groove 41 to avoid the pole lug from being skewed, so as to facilitate the pole lug to enter the pole lug lead-out groove 42 one by one. A soft pad can be set on the pushing surface of the butt plate 92 to avoid the pole lug from being squeezed and damaged.

[0054] See also Figure 8-Figure 10 As shown, the intermediate supporting assembly 10 includes a fourth telescopic rod 101 and an L-shaped support plate 102. The fourth telescopic rod 101 is preferably an electric or pneumatic telescopic rod. A second groove 44 is provided on the inner side wall of the pole lug outlet groove 42. The second groove 44 is located below the first groove 43. A bridging groove 45 is provided on the inner side wall of the pole lug outlet groove 42 and directly opposite to the second groove 44. The fourth telescopic rod 101 is installed in the second groove 44, and the L-shaped support plate 102 is installed at the output end of the fourth telescopic rod 101. One end of the L-shaped support plate 102 facing the bridging groove 45 is inserted and matched with the bridging groove 45, and the distance between the supporting surface of the L-shaped support plate 102 and the upper end of the pole lug outlet groove 42 is greater than the width of the pole lug, so that when the abutment plate 92 is used to press the pole lug in the pole lug storage groove 41, the bottom end of the abutment plate 92 will not touch the pole lug in the pole lug outlet groove 42.

[0055] In summary, the staff can first place multiple tabs neatly in the tab storage slot 41 with their long sides facing downward, and use the L-shaped support plate 102 to block the bottom end of the tab outlet slot 42 to form a tab temporary storage area, and then use the second telescopic rod 72 to drive the push plate 71 to push a tab into the tab temporary storage area, and then use the abutment plate 92 to press the tab near one end of the tab outlet slot 42. This is the initial preparation state. Then, as the multi-axis mounting frame 2 drives the laser welding gun 3 and the material guide track 5 to adjust, the movable material guide portion 5 2 is above the battery cell to be welded, at this time, the controller synchronously controls the fourth telescopic rod 101 to start, the fourth telescopic rod 101 retracts to open the bottom end of the tab lead-out slot 42, and a tab in the tab temporary placement area can be slid along the fixed material guide portion 51 to the movable material guide portion 52, and is blocked by the blocking bar 521 of the movable material guide portion 52 (after the tab in the tab temporary placement area is moved out, the fourth telescopic rod 101 is immediately restored to its original state, and the bottom end of the tab lead-out slot 42 is blocked by the L-shaped support plate 102), and then the suction cup 622 is used. Suction the middle part of the upper end surface of the pole ear, then use the bidirectional telescopic rod 612 to synchronously move the two movable material guide parts 52 outward to release the supporting effect of the movable material guide part 52, and then use the first telescopic rod 621 to drive the pole ear to move downward so that the pole ear fits on the battery cell of the battery pack to be welded, and then the laser welding gun 3 can be used to weld one end of the pole ear, and then the laser welding gun 3 is moved to the other end of the pole ear through the multi-axis mounting frame 2 for welding. At the same time, the controller controls the second telescopic rod 72 to drive the push plate 71 to push a pole ear into the pole ear temporary storage area, and so on. The cycle is repeated, and the relevant driving devices (such as motors, telescopic rods, etc.) will gradually transport the pole ear to a specific loading position according to the established timing and rhythm, and can realize continuous and automatic loading of the pole ear to ensure that each pole ear can be accurately and efficiently loaded. The entire system operates stably and continuously under a highly automated and precisely controlled environment, which greatly improves production efficiency and reduces the uncertainty and error caused by manual intervention, providing reliable technical guarantee for large-scale, high-quality pole ear welding production.

[0056] In addition, after the battery tabs are welded to the battery cells of the two combined batteries, the multi-axis mounting frame 2 is immediately used to control the movement of the movable material guide part 52, so that the lower end surface of the movable material guide part 52 can be used to press the welded weld part. By squeezing the welded weld part, the weld can produce a certain plastic deformation under the action of pressure. This deformation can make the metal at the weld fit more closely together, thereby filling pores, bridging tiny cracks, enhancing the integrity of the weld joint, and effectively improving the welding strength; secondly, squeezing the weld part can make the weld surface smoother and smoother, thereby achieving the shaping of the appearance of the weld.

[0057] Example 2: Please refer to Figure 6-Figure 7As shown, this embodiment is an extension of Embodiment 1: a guide groove 615 is provided at the bottom end of a side of the fixed material guide portion 51 facing the movable material guide portion 52, and a guide bar 614 is fixed at the bottom end of a side of the movable material guide portion 52 facing the fixed material guide portion 51, and the guide bar 614 is slidably fitted in the guide groove 615.

[0058] Through the above, the guide groove 615 provides a stable and unique sliding path for the guide bar 614. This sliding cooperation method effectively limits the unnecessary displacement and shaking of the movable material guiding part 52 in other directions, so that it can only perform smooth and precise linear sliding along the direction determined by the guide groove 615, thereby providing a reliable guarantee for the smooth transmission of materials. This not only greatly improves the stability and accuracy of the material guiding process, but also avoids problems such as jamming and deflection of materials due to misalignment or shaking of the material guiding parts during the guiding process. Among them, a ball bearing can be arranged in the guide groove 615 to help reduce the noise and friction during the movement of the movable material guiding part 52.

[0059] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0060] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
