[0002] Lithium batteries have been widely used due to their advantages such as light weight, large capacity and no memory effect. Among them, rectangular lithium batteries are usually used as power batteries in new energy electric vehicles. Before lithium batteries are put into use, many lithium batteries need to be welded in series and parallel to achieve the voltage and energy capacity required by new energy electric vehicles.

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-5As shown, a lithium battery processing welding device includes a base 1, which can support the device. A guide rail 2 is bolted to the top of the base 1. The cross-sectional shape of the guide rail 2 is an I-shaped design. A welding component 3 is slidably connected to the surface of the guide rail 2 (the welding component 3 is a prior art, which has the function of moving on the surface of the track 2. The means in the prior art are adopted and will not be described in detail here). With the cooperation of the guide rail 2 and the welding component 3, the device can weld lithium batteries at different positions. A hydraulic rod 4 is bolted to the inner cavity of the base 1. A rotating mechanism 5 is provided at one end of the hydraulic rod 4, and a connecting plate 6 is installed in the inner cavity of the base 1. With the cooperation of the hydraulic rod 4 and the rotating mechanism 5, the connecting plate 6 can be rotated in the inner cavity of the base 1. A fixing plate 7 is bolted to the top of the connecting plate 6, and a rotating shaft 8 is fixed to the inner cavity of the fixing plate 7. A torsion spring 9 is bolted to the inner cavity of the fixing plate 7. A limiting plate 10 is fixed to one side of the rotating shaft 8. One side of the limiting plate 10 is fixedly connected to one side of the torsion spring 9. The surface of the limiting plate 10 is slidably connected to the inner cavity of the fixing plate 7. The top bolt of the limiting plate 10 A guide rod 11 is connected, and the guide rod 11 is T-shaped. A moving rod 12 is fixed on one side of the welding assembly 3. Under the action of the welding assembly 3, the moving rod 12 can be moved to the top of the guide rod 11, so that the guide rod 11 drives the limit plate 10 to rotate in the inner cavity of the fixed plate 7 away from the lithium battery through the rotating shaft 8, so that the welding assembly 3 can weld the lithium battery, and under the action of the three limit plates 10, the other two places of the welding assembly 3 can be effectively prevented from being offset due to vibration during welding, thereby preventing the lithium battery from being damaged by welding, and increasing the use effect of the device. The horizontal height of the moving rod 12 is lower than the horizontal height of the welding assembly 3, and the width of the bottom of the moving rod 12 is greater than the maximum width of the guide rod 11, which can prevent the welding assembly 3 from blocking the rotation of the limit plate 10. A cooling mechanism 13 is provided on the top of the base 1. The cooling mechanism 13 can cool the device during welding, preventing the high temperature from causing heat to be transferred to the inside of the lithium battery to cause damage, thereby improving the quality of lithium battery processing and production.
[0026] The rotating mechanism 5 includes a rack plate 51, one end of which is fixedly connected to the output shaft of the hydraulic rod 4, a spur gear 52 is meshed on one side of the rack plate 51, a rotating rod 53 is fixed to the inner cavity of the spur gear 52, the surface of the rotating rod 53 is fixedly connected to the bottom of the connecting plate 6, and one end of the rotating rod 53 is fixedly connected to the inner cavity of the base 1 through a bearing seat. Under the action of the hydraulic rod 4, the rack plate 51 can drive the rotating rod 53 to rotate through the spur gear 52, and the rotating rod 53 can drive the fixed plate 7 to rotate through the connecting plate 6, so that the lithium battery can be limited, effectively preventing the lithium battery from being offset during operation and causing inaccurate welding position, and preventing the lithium battery from being damaged due to welding, thereby reducing the cost of producing lithium batteries. The number of rack plates 51 and spur gears 52 is two and they are symmetrically designed with the central axis of the base 1, which can make the connecting plate 6 more stable when rotating, thereby increasing the stability of the device.
[0027] The cooling mechanism 13 includes a fixed shell 131, the bottom of the fixed shell 131 is bolted to the top of the base 1, a ventilation plate 132 is fixed to the inner cavity of the fixed shell 131, and a fan 133 is installed in the inner cavity of the fixed shell 131. With the cooperation of the fan 133 and the ventilation plate 132, the wind source can cool down the welding component 3 during welding, effectively preventing the high welding temperature from causing damage to the lithium battery, improving the quality of the finished products of the lithium battery processing, thereby increasing the welding effect of the device. The number of cooling mechanisms 13 is three and they are symmetrically designed with the central axis of the base 1, which enhances the cooling effect of the device during welding.
[0028] Working principle: First, the staff places the lithium battery to be welded on the top of the base 1, and then uses the hydraulic rod 4 to make the rack plate 51 drive the spur gear 52 to rotate. The spur gear 52 drives the connecting plate 6 to drive the fixed plate 7 to rotate in the direction of the lithium battery through the rotating rod 53, so that the bottom of the fixed plate 7 and the limit plate 10 are tightly fitted with the top of the lithium battery. When welding begins, the staff moves the position of the welding assembly 3 through the guide rail 2. After the welding assembly 3 moves to the top of a limit plate 10, the welding assembly 3 drives the moving rod 12 to descend, so that the moving rod 12 drives the guide rod 11 to rotate in the direction away from the lithium battery. At the same time, under the action of the rotating shaft 8, the limit plate 10 can rotate along with the guide rod 11. Move to allow the limit plate 10 to temporarily move away from the unwelded position, while the limit plates 10 at other positions can still limit the connecting plate, so that the welding assembly 3 can weld the connecting plate at the bottom of the limit plate 10. After the welding is completed, the moving rod 12 moves upward through the welding assembly 3, and under the action of the torsion spring 9, the limit plate 10 can be returned to its original position. Then the welding assembly 3 moves to the top of the other two limit plates 10 through the guide rail 2, and repeats the above steps to weld the connecting plates. When one side of the welding is completed, the staff rotates the lithium battery to weld the other side. At the same time, under the action of the cooling mechanism 13, the situation in which the welding temperature is too high and affects the lithium battery can be prevented. When all welding is completed, the staff can take out the lithium battery.
