Omnidirectional lithium battery pack industrial welding robot

Abstract

The invention discloses an omnidirectional lithium battery pack industrial welding robot and relates to the technical field of welding robots. The omnidirectional lithium battery pack industrial welding robot comprises a welding base. Support frames are arranged on two sides of the upper end of the welding base. A top frame is arranged at the top ends of the support frames. A motor frame is arranged on the middle portion of the lower end of the welding base. A vertical motor is arranged at the lower end of the motor frame. Vertical screw rods are connected to an output shaft of the vertical motor through belt transmission mechanisms. Threaded blocks are connected to the middle portions of the vertical screw rods through a threaded structure. Lifting blocks are arranged at the rear ends ofthe threaded blocks. Horizontal guide rods are arranged between the upper ends of the lifting blocks and between the lower ends of the lifting blocks. A moving block is arranged in the middle of the horizontal guide rods. A horizontal screw rod is connected to the middle of the moving block through an internal threaded hole. A fixing rack is arranged in the middle of the front end of the moving block. A back-and-forth moving box is arranged in the middle of the fixing rack. By means of the omnidirectional lithium battery pack industrial welding robot, the omnidirectional movement of a weldinghead in back-and-forth, left-and-right and up-and-down directions is realized, a lithium battery does not need to be moved in the welding process, and the welding quality and the welding efficiency are greatly improved.

Description

technical field [0001] The invention relates to the technical field of welding robots, in particular to an all-round industrial welding robot for lithium battery packs. Background technique [0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, M. S. Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream now. [0003] The connecting pole piece of lithium battery is usually made of nickel material. At present, the typical welding methods include single-phase AC welding, DC welding capacitor energy storage type o...

AI Technical Summary

Problems solved by technology

When the ordinary single-phase AC welding method is used, due to the long power-on time, it is easy to cause serious oxidation on the surface of the pole piece, a lot of spatter, and the welding quality is not high.

When the simple DC welding method is used, although the short power-on time will not cause surface oxidation, there will be welding polarity effects, that is, the size and strength of the two solder joints are inconsistent, which will affect the welding effect.

[0004] Existing welding robots cannot completely weld in all directions during welding, which makes the position of the solder joints inconsistent and affects the appearance of the product, and the welding head cannot adjust the welding position with the change of the lithium battery model

Chinese patent (notification number: CN208067631U) discloses a lithium battery welding robot, including a servo motor and a conveyor belt driven by a driving wheel and a driven wheel, and the servo motor is arranged in the middle of the left ends of the driving wheel and the driven wheel , the servo motor and the conveyor belt are set horizontally on the ground through the bracket. Although this device increases the welding effect to a certain extent, in actual welding, we cannot accurately ensure the placement position of the lithium battery, so we need to The position of the welding head is adjusted. Obviously, the device cannot adjust the corresponding position. Therefore, it needs to be improved to meet the needs of all-round welding.
