The present disclosure relates to the field of SMC(T) cross-wiring devices, and more particularly, to a cross-wiring calibration and positioning method for solder paste printing of single or multiple pieces of PCB (printed circuit board) or FPC (flexible printed circuit) subjected to compensation calculation through visual software.
Existing cross-wiring solder paste printers all employ a whole panel for solder paste printing. A whole panel yield of a single piece of PCB or a FPC solder paste printing workpiece does not reach 100% during production, and there will be several pieces of defective products. In the case of the solder paste printing of the whole panel, the cross-wiring solder paste printer has a stiff problem in mechanism due to a solder paste printing steel plate, and the piece of defective products cannot be bypassed by system operation. The traditional method for the defective piece is to manually apply a kraft paper tape to cover the piece in order to avoid waste of solder paste. The additional thickness from the paper would affect the overall printing quality and is prone to short-circuit. It also lead to additional human labor and thus higher cost.
In order to overcome the defects in the existing technology, the present disclosure provides a cross-wiring calibration and positioning method for solder paste printing of single or multiple pieces of PCB or FPC.
The technical solutions used in the present disclosure to solve the technical problem are as follows.
A cross-wiring calibration and positioning method for solder paste printing of single or multiple pieces of PCB or FPC includes the following steps of:
As a preferred option, in the step 1), the lower carriers are delivered to a first AB switching-type conveying station by lifting the lower turning conveying carrier-plate feeder, the lower carriers are respectively conveyed to separate loading regions in an alternating manner, and the lower carriers are respectively conveyed to the lifted photographing workstation in an alternating manner through a second AB switching-type conveying station from the loading regions.
As a preferred option, in the step 1), the PCB or FPC solder paste printing material is sucked and transferred into the loading region through a robotic arm equipped with suction module.
As a preferred option, in the step 1), the PCB or FPC solder paste printing material is grasped and transferred into the loading region through a robotic arm equipped with a clamping claw.
As a preferred option, in the step 1), the PCB or FPC solder paste printing material is sucked and transferred into the loading region through an XYZ linear sliding table (line code) equipped with suction module.
As a preferred option, in the step 1), the PCB or FPC solder paste printing material is grasped and transferred into the loading region through an XYZ linear sliding table (line code) equipped with a clamping claw.
As a preferred option, in the step 8), a suction mode or an adhesion mode and a positioning pin positioning mode are employed as the fixing modes.
The present disclosure has the beneficial effects that: the cross-wiring solder paste printing device for the multiple pieces of fully qualified PCB (printed circuit board) or FPC (flexible printed circuit), which performs the steps of cross-wiring, transfer and delivery, material taking and discharge, independent suction type XYθ calibration platform, high-speed transfer, multi-stage lifting, and alternating plate feeding without idling, and the high-precision solder paste printing process mode can effectively improve production efficiency (fully qualified PCB or FPC), lower costs (without waste of older paste, thus environmental friendly), and shorten labor-hours for processing NG plates (the solder paste printing of fully qualified PCB or FPC), and multiple visual calibrations and signal handshaking for checking a coordinate effect are performed to maintain high-precision, high-accuracy, high-quality and high-yield cross-wiring solder paste printing, thus effectively reducing technical manpower and heavy labor (cost reduction) and achieving a more efficient production and manufacturing process technology.
The present disclosure is further described hereinafter with reference to the accompanying drawings and the embodiments.
With reference to
The method can effectively improve a production efficiency and lower costs, is environmentally friendly, shortens PASS labor-hours for processing NG plates, and has the advantages of effectively maintaining high-precision cross-wiring solder paste printing and high-quality solder paste printing, and reducing manpower and repeated work.
In the above step 8), a suction mode or an adhesion mode and a positioning pin positioning mode are employed as the fixing modes.
The PCB or FPC solder paste printing material 102 may be delivered and positioned through a robotic arm equipped with suction module or a clamping claw, and an XYZ linear sliding table equipped with suction module or the clamping claw.
In order to improve a working efficiency, the lower carrier 101 is delivered to a first AB switching-type conveying station 106 by lifting a lower turning conveying carrier-plate feeder 1. The first AB switching-type conveying station 106 alternately transports the lower carrier 101 to a first loading region or a second loading area, and the first loading area or the second loading area alternately transports the PCB or FPC solder paste printing material 102 positioned with the lower carrier 101 through a second AB switching-type conveying station 107.
According to the above principle, the above embodiments may also be appropriately changed and modified in the present disclosure. Therefore, the present disclosure is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present disclosure shall also fall within the scope of protection of the claims of the present disclosure.
