However, the present invention is not limited to the above embodiment, and two vacuum generators 10 may be provided, and each vacuum generator is directly connected to the vacuum chuck through the exhaust pipe, so that the same suction force or different suction forces may be applied to the first vacuum chuck 41 and the second vacuum chuck 42.
The battery pull force testing assembly may include a vacuum generator 10. The vacuum generator 10 includes an air supply port 11, an air suction port 12, and an exhaust port 13. The suction port 12 is connected to a second end of the third suction pipe 23, and the air supply port 11 is connected to an air source, which supplies compressed air to the vacuum generator 10 through the air supply port.
When the vacuum generator 10 is started, the air supply port 11 supplies compressed air to the vacuum generator 10, the compressed air forms a high-speed airflow in the pump body, the air in the first vacuum chuck 41 and the second vacuum chuck 42 is gradually extracted by the extraction port 12 through the high-speed airflow, the atmospheric pressure in the first vacuum chuck 41 and the second vacuum chuck 42 is gradually reduced and is lower than the external atmospheric pressure, negative pressure is formed in the vacuum chucks, and the negative pressure adsorbs the second surface of the battery 50. The higher the vacuum degree in the vacuum chuck is, the larger the negative pressure adsorption force is, and the larger the acting force between the vacuum chuck and the battery is. When the vacuum generator 10 stops operating, the drawn air and the compressed air may be discharged to the outside through the discharge port 13.
The present invention is not limited to this, the vacuum generator 10 may include a suction pump, start the suction pump, and gradually take out the air in the first vacuum chuck 41 and the second vacuum chuck 42 through the air extraction opening 12, thereby also absorbing the battery 50 through the vacuum chuck. By controlling the power of the suction pump, the suction force of the vacuum chuck to the battery 50 can be adjusted.
The drawing machine is started, the pulling force applied by the drawing machine acts on the universal lifting ring 34, the pulling force acts on the second surface of the mobile phone battery 50 through the stress part 341, the acting force applied by the drawing machine is the drawing force of the battery at the moment, and therefore whether the gum of the battery meets the design requirement or not can be effectively detected.
