An automatic plate placing machine with ejector pin

Abstract

The present invention provides an automatic ejector plate placing machine. During operation, ejectors to be placed are arranged in a series on each material receiving rod. When the material receiving plate slides to a specific position of the material pushing slide rail, the push cylinder drives each lifting clamp to clamp on a material clamp through the clamping slide plate, each lifting slide column, and the lifting connecting plate. The driving motor drives the lifting connecting plate through the lifting screw to drive each lifting clamp to move close to an abutment groove, thereby pushing the ejector to be placed at the top of each material receiving rod to the abutment groove. The longitudinal moving device of the swing plate drives the ejector swing plate to drive each moving column in a row of moving columns close to the lifting top plate to insert into an abutment groove and pass through an ejector to be placed. The transverse moving device of the swing plate drives the longitudinal moving device of the swing plate to move the ejector to be placed in the abutment groove by a specific distance so that the ejector to be placed is moved to the slideway. The specific distance is the spacing between each column of moving columns. It is efficient to place the mobile phone card removal needle on the needle plate.

Description

Technical Field

[0001] The invention relates to the field of mobile phone ejector pin production, in particular to an ejector pin automatic placing machine. Background Art

[0002] The card ejector pin is a card ejection tool that is now equipped with most high-end mobile phones. The card ejector pin provides a convenient way to remove the phone card or memory card for some mobile phones whose batteries cannot be removed. The card ejector pin is a way to extract the card in a way that saves internal space in the mobile phone. These mobile phones that usually use the card ejector pin use a smaller card model than ordinary SIM cards. The card slot is usually located on the side of the body and has a hole-shaped switch designed for card extraction. This design is similar to the emergency ejection hole of a computer optical drive. When in use, insert the card ejector pin into the perforation to trigger the hole-shaped switch, and the hole-shaped switch will eject the phone card or memory card from the card slot, making it easier for users to replace the phone card or memory card.
