Description

Technical Field

[0001] The invention relates to the technical field of mechanical assembly, and in particular to a cover plate positioning device. Background Art

[0002] The positive and negative electrode pads need to be installed on the lithium battery cover. In order to ensure the installation strength and insulation, it is necessary to apply insulating glue to the pad installation holes of the cover. There are two inlay bosses on the front of the cover, which are used to install the positive and negative electrode pads. In addition, there are two anti-fool convex points on one side of the lower end of the cover, such as Figure 4 As described above, the positioning and installation of the cover plate directly affects the subsequent installation of the positive and negative electrode pads of the lithium battery. The cover plate is often grabbed by a robot. At present, a common problem is that the front and back of the cover plate are wrong. The cover plate has a non-axisymmetric structure and the horizontal plane is often placed wrong. It is difficult for the robot to solve the above problems. Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a cover plate positioning device. Summary of the invention
