Differential Pressure Leak Measuring Machine For Battery Production Line

Differential Pressure Leak Measuring Machine For Battery Production Line

1. Brief description of leak detection machine
The machine is suitable for leak detection of square steel shell battery charged with 0.1mpa positive pressure gas.
2. The design requirements
2.1. This equipment is in the air (nitrogen) to test for the medium, the air (nitrogen) injection seal housing (such as aluminium, steel battery shell welding, injection molding plastic battery shell) and standard cavity, reach the set pressure, keep a certain time, the pressure balance, precision differential pressure sensors, the test of time, the differential pressure sensors measure the standard of vessel and checked the product pressure difference in the airtight system, on the basis of judging shell pincer-like device sealing quality.
 
2.2. Workflow: preparation -- pressure -- balance -- test -- exhaust -- determination.
 
2.3. Manually push the hot-melted battery into the positioning position, block the cylinder and block the battery, and the sensor detects the electricity
 
After the pool, clamp the battery; Press down the sealing mouth, seal the battery, and start the inflation detection.
 
2.4. A battery is clamped by a person, and the battery is tested by the testing instrument. After the test, the battery is pushed out manually.
 
2.5. Battery after hot fusion welding: length: 240mm, width: 110mm, thickness: 40mm.
 
2.6. Main components of equipment

2.7. Equipment technical parameters

 
 
2.8. Device outline view

 
2.9. Description of main equipment components
 
2.9.1 battery positioning and clamping system: manually place the battery on the movable positioning platform, move the rear positioning cylinder forward to compress the battery, and adjust the front positioning mechanism according to the battery size.
 
2.9.2 battery shell pressurization system: after pressing the start switch, the inflatable positioning mechanism will press down, the soft rubber head will automatically seal the battery hole, the testing instrument will be started and inflated, and the pressure will be changed within the required time according to the set air pressure. (the charging time and the charging size can be set according to the battery volume.) Due to the different battery models, the external dimensions of each battery will change differently, so there are adjustment screws and t-type adjustment on the bracket Block, can quickly and conveniently change different width and height, so as to achieve different types of batteries. The cylinder is pressed down to the air hole of the battery, and the battery is charged into the testing instrument to check whether the battery is leaking air. (this part of the mechanism can be adjusted according to the shape of the battery size, suitable for various types of battery detection, adjustment is convenient and simple.)
 
2.9.3. Test instrument: this test instrument is a test method that injects pressure air into the test article (workpiece) and measures the change of its internal pressure to detect whether there is leakage. The test product is first injected with pressurized air. The gas is then stopped and a sensitive differential pressure sensor (DPS) is used to measure the internal pressure change caused by the leak, that is, the differential pressure between the test and the standard.
 
2.9.4. Rack system: 120120 square pass welding structure, surface baking paint, the main color of equipment appearance is gsb05-1426-2001 8 PB07 light (iron) blue color. The base plate is made of mirror stainless steel, and other parts are plated with A3 steel.
 
2.9.5. Control system: the machine shall be equipped with an electric plate, leakage switch, dc stability power supply and other power circuit components, control relays, solenoid valve control devices and so on. And external connection, using connectors and terminal table. The relay USES omron. Cables and air ducts between other equipment are wired and piped below.
