Vacuum Chamber Helium Leak Detection System for New Energy Vehicles Power Relay
The equipment has 3 vacuum chambers that operate in tandem , thus, only one operator can run the equipment.
The workpiece is automatically detected in a vacuum chamber. The vacuum chamber adopts a bell-type structure and can be opened and closed automatically. The operator only needs to load and unload the workpieces, and the loading and unloading are simple and convenient.
Up to 5 workpieces can be installed on the fixture in vacuum chamber at a time. If there is no need to install 5 workpieces, the corresponding workpiece mounting holes can be plugged with plugs.
The German INFICON leak detector is used for inspection, and the maximum leak detection accuracy can reach 5 x 10-12 Pa.m3/s. Gross leaks and fine leaks can be identified during detection process, saving helium gas consumption.
Adopt imported brand vacuum pumps, to achieve a leak detection accuracy of 10-9 Pa.m3/sec and 90-second detection cycle, the system is equipped with a rough pump, a fine pump, and a leak detection pump. The vacuum of the leaking pump group can reach 10-6Pa. HongCe has experience in automated helium leak detection systems with 10-10Pa.m3/sec accuracy.
The short distance between the valve and the workpiece is sufficient to reduce the production cost. The connection between the workpiece and the equipment has a filter to prevent the contaminants in the workpiece from clogging the valve.
The system is controlled by the PLC. And display a variety of information on 10” color touch screen.
With a computer, and with two-dimensional workpiece code scanning & information storage system: combined by a two-dimensional scanning code reader and a computer, read the workpiece data, product code, detection time, operator, total production, good yield, not Good yield, etc. by the two-dimensional code, and can export EXCEL files, the software has a variety of models to meet the specifications and parameter memory. The operation is simple and convenient.
With safety protection , emergency stop and reset functions.
Equipment design meets ergonomic requirements.
Basic technical indicators:
