Description

Technical Field

[0001] The present invention relates to the technical field of CCD screen pasting machines, and in particular to an alignment and pasting fixture of a CCD screen pasting machine for a bent liquid crystal screen. Background Art

[0002] When attaching screens to electronic products, such as mobile phones, the electronic products (mobile phones) and the screens are separated by cardboard in the initial state. The existing technology generally attaches screens manually, and the screen attaching position is inaccurate, which increases the labor intensity of manual screen attaching and also increases the production cost. Therefore, it is necessary to provide an automatic screen attaching machine. First, the electronic product (mobile phone) is placed in a carrier, and the carrier clamps the cylinder to clamp and position it. The suction cup on the carrier absorbs the electronic product; at the same time, a light source is provided for the camera to position the camera for taking pictures; then the Z-axis module moves down to contact the screen to absorb the screen, separate the screen from the cardboard, and manually remove the cardboard. The camera automatically adjusts its position to ensure that the focal length is aligned with the position of the screen to be attached to the electronic product; then the camera takes pictures to position it, and the carrier adjusts the X, Y, and angle positions for alignment, and then the screen is attached.

[0003] Existing CCD screen laminating machines can only meet the needs of automatic alignment and lamination of straight-screen mobile phones or straight-screen LCD displays.
