Description

Technical Field

[0001] The present invention belongs to the technical field of PCB board production equipment, and specifically relates to a high-speed board-retracting and unretracting machine with an MES system and an automatic guided transport vehicle (AGV for short). Background Art

[0002] PCB (Printed Circuit Board) is a basic component widely used in various electronic related products. It is a substrate that carries electronic components and connecting components. In the production and processing of printed circuit boards, in order to meet the needs of the automation of the overall processing production line, a board placing machine is set at the starting point of the production line and a board collecting machine is set at the end of the production line to facilitate the processing of printed circuit boards. The board placing machine can place the circuit boards horizontally one by one on the conveyor belt of the production line. When the circuit boards are processed, the board collecting machine will collect the circuit boards on the conveyor belt of the production line.

[0003] At present, all PCB retractors are simply customized according to a certain production line. The equipment is manually loaded and unloaded, and the general operation method is: 1. Manually input production information such as material number and quantity; 2. The equipment is equipped with a code reader, and the QR code or barcode on the material card is manually scanned and compared with the information in the ERP to obtain the production information equipment to obtain the information of the current production product. This method is not only complex and passive, but also the retractor cannot automatically know the material number of the current production product. There are many errors caused by human factors and they cannot be traced.

[0004] At present, PCB retractors are only suitable for general production lines, with a production efficiency of 6 Panal / min (with paper separators) or 10 Panal / min (without paper separators). With the continuous improvement of PCB technology, the speed of production lines is getting faster and faster, and the efficiency of this type of retractor has gradually failed to meet production needs. In terms of continuous production, the equipment generally increases the number of stations to achieve continuous production (4 stations with paper separators and double stations without paper separators). It occupies a large area and has a low degree of automation. It is impossible to automatically switch the carrier. The carriers applicable to the equipment are also relatively single, which is not suitable for high-end production lines (such as Msap products). In addition, the equipment can only feedback production information through the touch screen. Due to the limitations of the touch screen function and size, the feedback information screen is small, which is not conducive to personnel reading, and is not suitable for high-end production lines.

[0005] The purpose of the present invention is to provide a high-speed plate-retracting and unretracting machine with an MES system and an automatic guided transport vehicle (AGV vehicle for short) to overcome the problems existing in the prior art of the plate-retracting and unretracting machine, such as manual loading and unloading, inability to trace human errors, low efficiency, large footprint, inability to realize automatic switching of carriers, single applicable carrier, and inconvenient information reading.

[0008] The AGV vehicle is connected to a separate MES system via a communication cable, and the MES system collects product information such as material number, product size, quantity, etc., and performs centralized information scheduling.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] The high-speed board-retracting and unreeling machine with an MES system and an AGV vehicle of the present invention, the combination of a double workstation and a paper-separating platform not only realizes the problem of continuous production with paper-separating, but also realizes the universality of carriers, reducing the equipment footprint; the grab plate and grab paper-separating adopt different actuators to improve the equipment efficiency, reaching 12 Panal / min (with paper-separating); the production information is displayed on a large screen in a timely and effective manner, which is convenient for operators to read; the MES system is used to uniformly distribute production information and monitor and record the production status of each execution unit in real time, which can automatically obtain the material number of the product and produce according to the production plan, so as to realize the traceability of production information; the AGV vehicle's automatic loading and unloading of materials not only reduces the labor intensity of personnel but also realizes the automatic identification of product material numbers, eliminating the problem of manual input errors; through the customized design of the conveying section, the entire equipment meets the production requirements of high-end production lines in the PCB industry.
