Description

Technical Field

[0001] The invention relates to the technical field of chip welding devices, in particular to a chip welding device for manufacturing flip-type batteries. Background Art

[0002] Lithium-ion batteries are generally equipped with management chips and charging control chips. The management chip contains a series of registers that store values ​​such as capacity, temperature, ID, charging status, and discharge times. These values ​​will gradually change during use. The main purpose of the "full charge and discharge once every month" in the instructions for use should be to correct the improper values ​​in these registers so that the battery charging control and nominal capacity match the actual situation of the battery. The charging control chip mainly controls the charging process of the battery. The charging process of lithium-ion batteries is divided into two stages, the constant current fast charging stage (when the battery indicator light is yellow) and the constant voltage current decreasing stage (the battery indicator light flashes green). In the constant current fast charging stage, the battery voltage gradually increases to the standard voltage of the battery, and then enters the constant voltage stage under the control chip. The voltage no longer increases to ensure that it will not be overcharged, and the current gradually decreases to 0 as the battery power increases, and finally completes the charging.

[0003] During the production process of battery chips, the chips usually need to be welded, and usually both sides need to be welded, so welding equipment is needed to complete the welding operation. However, current welding equipment can usually only quickly weld one side of the battery, and manual re-positioning is required to continue welding. This not only wastes a lot of manpower and cannot achieve double-sided welding, but the frequent movement of battery chips can also easily reduce the welding accuracy. Summary of the invention

[0006] A welding mechanism, which is fixedly mounted on the output end of the second hydraulic rod and is also arranged above the placement frame, and is used to weld the upper and lower sides of the chip;

The side of the limit plate close to the rotating rod is provided with a matching plate, and the matching plate is arranged in an arc shape. The matching plate is symmetrically fixedly connected to the inner surface of the mounting frame, wherein the inner surface of the matching plate is arranged in contact with the outer surface of the transmission belt, and the outer surface of the limit plate is arranged in contact with the inner surface of the transmission belt. When the battery chip needs to be welded, the bracket dedicated to the battery chip can be installed on the mounting frame, and then the battery chip to be welded can be installed on the battery chip bracket, and then the mounting frame is driven to rotate. When the welding mechanism is misaligned with the mounting frame, the second hydraulic rod is driven to promote the welding The mechanism moves downward until the middle of the welding mechanism is at the same horizontal plane with the bracket for installing the battery chip. At this time, the driving mounting frame is reset, which will make the mounting frame close to the battery chip bracket and eventually cover the battery chip on the inside of the mounting frame. Then the second hydraulic rod is driven to move slightly, so that the welder installed on the transmission belt inside the mounting frame contacts the point on the upper surface of the battery chip to be welded and starts welding. When the upper surface welding is completed, the driving motor is operated. When the motor is started, it drives the rotating rod inside the mounting frame to rotate, and then the transmission belt starts to rotate along the surface of the rotating rod, the limit plate and the matching plate, and finally the welder moves to the bottom of the battery chip. At this time, the second hydraulic rod is fine-tuned to make the welder contact the welding point at the bottom of the battery chip and perform welding.

[0017] The present invention provides a chip welding device for flip-type battery manufacturing, which has the following beneficial effects:

[0018] 1. The flip-type chip welding device for battery manufacturing, by setting a U-shaped installation frame and cooperating with a transmission belt, allows the welder to move freely on the upper and lower sides of the battery chip for welding. Compared with manual adjustment of the upper and lower sides of the battery chip, the welding efficiency of the battery chip is greatly improved, and it can also avoid moving the battery chip multiple times so that the position of the battery chip needs to be adjusted constantly, resulting in welding errors. While improving the welding efficiency of the battery chip, it also greatly improves the welding quality of the battery chip and greatly reduces the possibility of generating waste points.

[0019] 2. The chip welding device for flip-type battery manufacturing elastically installs the grinding block so that the grinding block is initially located in the middle of the supporting plate, and sets the two ends of the grinding groove on the grinding block to a vertical shape, so that the welding head of the welding machine always moves into the grinding groove when it is repeatedly moved. When the welding head of the welding machine moves to the corrugated position of the grinding groove, since the welding head of the welding machine moves straight up and down relative to the grinding block, the welding head of the welding machine will intermittently drive the grinding block to reciprocate left and right in the slide groove as the welding head moves in the grinding groove, so that the welding head of the welding machine contacts and grinds the inner wall of the grinding groove in all directions, and the welding head of the welding machine is polished and cleaned to avoid residual impurities in the welding head of the welding machine, which leads to reduced welding quality at the welding point during continuous welding. By automatically cleaning the welding head of the welding machine during the welding process, the quality of the welding point of the battery chip is greatly improved, and the service life of the welding head of the welding machine is also greatly extended.

[0020] 3. In the chip welding device for flip-type battery manufacturing, since the cleaning groove and the grinding groove are in a connected state, the cleaning groove will be subjected to the air pressure transmitted from the elastic telescopic plate when the elastic telescopic plate is squeezed, and intermittently released outward through the grinding groove, that is, the impurities remaining in the grinding groove can be blown out and cleaned, so as to avoid the grinding groove being blocked by impurities and affecting the grinding and cleaning effect of the welding head of the welding machine, and also avoid the situation that the welding head is broken in the grinding groove due to the blockage of impurities. When the cleaning groove is subjected to the air pressure transmitted by the elastic telescopic plate, in addition to being released through the grinding groove, it is also released outward through the air outlet at the bottom of the grinding block, thereby cleaning the outer surface of the transmission belt, avoiding the impurities blown out through the grinding groove from staying on the transmission belt and finally entering the installation frame to cause the equipment to jam, thereby providing certain protection for the device itself, and also blowing out and cleaning the dust remaining in daily life, thereby further improving the welding accuracy and welding quality.
