Laminating process of flexible circuit board based on steel sheet laminating machine

Abstract

The invention discloses a flexible circuit board laminating process based on a steel sheet laminating machine. The process comprises the steps that a steel sheet manipulator moves a steel sheet sucker to a steel sheet stripping table to suck a steel sheet and moves to a lower detection component position; a CCD camera at the lower part of the lower detection component reads the direction of the steel sheet and inspects the steel sheet; the lower infrared sensor of the lower detection component senses and inspects the thickness of the steel sheet; the upper CCD camera of an upper detection component moves to a laminating platform position and identifies the placement position of a product board and a MARK point on a product to be laminated with the steel sheet; the upper CCD camera of the upper detection component inspects the steel sheet laminated on the product board; and the upper infrared sensor of the upper detection component senses and inspects the thickness of the steel sheet and the like. According to the invention, after the sucker of the steel sheet manipulator sucks the steel sheet, whether the steel sheet is sucked by the sucker can be judged through the vacuum value. The problems that the steel sheet is missed by the sucker; the laminating of the steel sheet is missed by the sucker; and product laminating is missed and poor are effectively prevented. According to the invention, the lower CCD camera and the lower infrared sensor are inspected before the steel sheet is laminated; a defective steel sheet can be checked out and discarded; the laminating yield of the steel sheet is improved.

Description

technical field [0001] The invention relates to the field of processing of flexible circuit boards, in particular to a laminating process of flexible circuit boards based on a steel sheet laminating machine. Background technique [0002] As the labor costs of enterprises increase and operators become scarcer, especially the manufacturing industry needs a large number of operators and the competition is fierce to control labor costs, the introduction of automation equipment has become an inevitable trend. In the manufacturing process of flexible circuit boards, there is a reinforcing and laminating process of steel sheets, PI, FR4, etc., to increase the load-carrying capacity of flexible circuit boards. Taking steel lamination as an example, steel sheets have been introduced. Production of sheet automatic laminating machines. The main mechanisms of commonly used steel sheet automatic laminating machines include loading / unloading manipulators, laminating platforms, steel sheet...

Problems solved by technology

Because this kind of automatic steel sheet laminating machine only completes the lamination of steel sheets, the identification of the direction of the steel sheet and the reading of the bonding position of the MARK point during the lamination of the steel sheet, but in the actual production process, a single During the production process of PCS steel sheet incoming materials, due to the limited production capacity, there may be contamination of steel sheet debris, scratches and damages on the rubber layer on the steel sheet, the size of the steel sheet does not meet the design requirements, two PCS steel sheets Defects such as partial overlap or complete overlap, especially for steel sheets with conductive adhesives, if the steel sheets are contaminated by debris, scratched, damaged, or poorly overlapped, the resistance of the steel sheets of the flexible circuit board will decrease after the steel sheets are bonded. The huge steel sheet resistance exceeds the hidden danger of the specification, resulting in defective products. Therefore, it is necessary to add a manual inspection of the steel sheet after the steel sheet is bonded. This increases the production time and labor cost of the product by adding a process. In addition, If the two steel sheets are completely overlapped, especially when the thickness of the steel sheets is only 0.1 or 0.15mm, after the two steel sheets are completely overlapped and bonded (the probability of this failure is relatively rare), it is generally at the PPM level (a few million) It is very difficult for employees to check out this defect due to negligence or other factors during product inspection. It is very likely that it will flow out to the client and cause customers to be unable to use it. Hundreds of thousands to millions of fines
