Description
Technical Field
[0001] The utility model relates to the technical field of top covers, in particular to a top cover injection molding die draft burr structure. Background Art
[0002] Lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and non-aqueous electrolyte solution. It is different from rechargeable lithium-ion battery and lithium-ion polymer battery. The inventor of lithium battery is Edison. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of microelectronics technology at the end of the 20th century, the number of miniaturized devices has increased, which has put forward high requirements for power sources. Lithium batteries have entered the large-scale practical stage.
[0003] During the production process, it was found that there were different burr problems on the plastic injection molding port of the lithium battery top cover. In the early stage, manual removal was used, which was time-consuming and laborious. In order to solve this problem, the utility model proposes a top cover injection molding port demolding burr structure. After the injection molding machine injects the top cover, it is sent to the conveyor belt. Through the photoelectric sensor, when the top cover is found, the clamper clamps the top cover into the lower mold of the tooling to form a positioning. At this time, the CCD detects whether the injection molding port meets the requirements. If it meets the requirements, it is sent to the next conveyor belt by the clamper. If it does not meet the requirements, the PLC sends a command, and this equipment runs once. During the process, the solenoid valve is opened, and the cylinder intake pushes the connecting end of the punch needle to the top cover. The punch needle is inserted into the two injection molding ports of the upper plastic, and the upper plastic is drilled and deburred. When the solenoid valve is closed, the CCD is turned on and turned on again for detection. If it meets the requirements, the clamper sends it to the next belt conveyor. For those that do not meet the requirements, the solenoid valve is opened again until it meets the requirements, thereby achieving a product qualification rate of 100%, solving the problems in the prior art.
