Description

Technical Field

[0001] The utility model relates to the technical field of battery tooling, and particularly relates to a pressure-holding suction cup fixture for soft-pack batteries. Background Technique

[0002] Suction cup fixtures are popular in the field of automated production lines due to their low cost. Considering the factor of production cost in the original design, a single vacuum generator is used for each clamping unit. Since the risk of battery explosion is relatively high, in the lithium battery industry, production safety is a key point in equipment manufacturing. In the existing technology, in the case of air leakage or air cut-off, only a one-way valve is used to achieve the pressure-holding function to meet the basic requirements. For example, in the existing technology, there are a total of eight suction cups in the fixture, and every four suction cups can clamp a soft-pack battery. Four vacuum suction cups with one-way valves are used within a single clamping unit. The pipe interfaces of the four suction cups are converted into one pipe interface through three Y-shaped adapters and connected to the vacuum generator, and the pneumatic circuit is relatively simple. When the vacuum generator fails, a single pneumatic circuit cannot ensure a vacuum environment. At this time, only the one-way valves of the four suction cups are relied on to block the air path to protect the vacuum state inside the suction cups, and the safety is insufficient. Content of the Utility Model

[0003] The purpose of the utility model is to provide a pressure-holding suction cup fixture for soft-pack batteries to solve the above problems.

The sensor 7 can be used to detect the incoming soft-pack battery, so as to transmit a signal to the vacuum generator 4, enabling the suction cup 2 to adsorb the soft-pack battery.

[0035] Optionally, a first through groove 1011 and a second through groove 1012 are formed on the surface of the horizontal plate 101.
