Description

Technical Field

[0001] The invention relates to the technical field of electronic product processing, and in particular to a glue sticking machine for FPC. Background Art

[0002] The labeling process of flexible printed circuit (FPC) includes loading and unloading, automatic mounting, automatic pressure holding and other steps. Although FPC flexible printed circuit board has become the preferred material for many consumer electronic products due to its excellent flexibility, light weight and high integration. However, due to its soft and easy to deform characteristics, accurate positioning and stable bonding during the labeling process have become a major problem. The labeling process usually includes key steps such as loading and unloading, automatic mounting and automatic pressure holding. The accuracy and efficiency of these steps directly determine the quality and production efficiency of the final product.

[0037] Working process: The workpiece (FPC board) is positioned on the support plate 5; The distance between the lateral movable support rails 24 and the lateral fixed support rails 23 on both sides of the support plate 5 is adjusted by the distance adjustment drive motor 223, so that the front conveying drag chain assembly 25, the middle conveying drag chain assembly 26 and the rear conveying drag chain assembly 27 can adapt to the width of the support plate 5; The workpiece first enters the front conveyor drag chain assembly 25; that is, the two sides of the support plate 5 are supported on the front conveyor belts 251 on the left and right sides. As the front drive motor 255 is started, the front conveyor belt 251 transports the support plate 5 to the cache position, waiting for the workpiece on the middle conveyor drag chain assembly 26 to complete labeling; Then, the workpiece enters the predetermined position in the middle conveying drag chain assembly 26 from the front conveying drag chain assembly 25; In the positioning module 6, the lifting platform 61 is driven by the lifting motor 62, and the heating plate 63 and the suction cup assembly 64 on the lifting platform 61 are lifted together, the suction cup assembly 64 adsorbs the bottom surface of the support plate 5, and the heating plate 63 heats the workpiece on the support plate 5; In the mounting assembly 3, the mounting head 32 moves to the top of the workpiece, detects the positioning point on the workpiece, and completes the identification of the workpiece position; then, the mounting head 32 moves to the feeder 4 to pick up the material and attaches the label to the workpiece; in this reciprocating manner, the labeling operation of the entire workpiece is completed; Finally, the suction cup assembly 64 releases the support plate 5 and descends; the workpiece enters the rear conveying drag chain assembly 27 from the conveying drag chain assembly 26 and is sent out.
