Abstract

The invention discloses a precise rotating, aligning and pre-pressing execution mechanism of a bonder and solves the problem that existing bonding rotating positioning mechanisms are low in stabilityand aligning accuracy. A pressing-down rotating spline shaft (3) is movably arranged in a rotating bearing (4), an adsorption head mechanism (2) is arranged at the lower end of the pressing-down rotating spline shaft (3) below the rotating bearing (4), the upper end of the pressing-down rotating spline shaft (3) above the rotating bearing (4) is connected with a rotatable output shaft of a rotatable pre-pressing cylinder (16), a screw module (14) moving horizontally is fixedly arranged on the vertical face of an inverted-L-shaped mounting plate (19), a rotating cantilever swing rod (6) is fixedly connected on the pressing-down rotating spline shaft (3) above the rotating bearing (4), a pin shaft and a cam driven bearing (7) are fixedly arranged on the upper end face of the outer side of the rotating cantilever swing rod (6), and the cam driven bearing (7) and a push rod (8) are in movable leaning-against connection. Rotating positioning accuracy is improved.

Description

technical field [0001] The invention belongs to the field of electronic communication technology manufacturing, in particular to an automatic alignment and preloading actuator in a fully automatic bonding machine. Background technique [0002] In the field of electronic communication technology, IC chip (Integrated Circuit integrated circuit) is to integrate a large number of microelectronic components on a plastic base to make a chip. Liquid Crystal Display (LCD) is called Liquid Crystal Display in English, which is a display that uses liquid crystal to control light transmittance technology to achieve color. Bonding COG is the abbreviation of chip onglass, that is, the IC chip is directly bonded on the LCD screen. COG bonding machine is the key equipment for manufacturing mobile phone, PDA, MP3 and other high-end electronic liquid crystal display modules. This equipment adopts machine vision alignment technology and precision motion control technology to realize fine-pitc...
