Abstract
The invention relates to a printed circuit board (PCB) transportation connection control circuit which mainly comprises the core component of a programmable logic controller (PLC), a head end photoelectric sensor, a tail end photoelectric sensor, an alarming system, a stepping motor, a chain and the like. The PLC receives information of photoelectric precision sensors installed at the head end and the tail end of a PCB transportation buffer conveyor to control stopping and rotating of the stepping motor, so that the chain is driven to move, and the functions of transportation, buffering and the like of a PCB on the transportation buffer conveyor can be achieved. The PCB transportation connection control circuit utilizes a photoelectric fine induction system, is mainly applied to PCB transportation, and is matched with a surface mounting technology (SMT) device to automatically control the temporary stopping and the transporting of the PCB. Accordingly, the whole technological process achieves full-automatic operation.
Description
Technical field
The control system field of the field that the present invention relates to a kind of electronic product transportation particularly relates to PCB transportation plug into control circuit field.
Background technology
Electronic circuit surface installation technique (Surface Mount Technology, SMT), be called surface mount or surface mounting technique, it is a kind ofly will (be called for short SMC/SMD without pin or short leg surface-assembled components and parts, Chinese title sheet components and parts) be arranged on printed circuit board (Printed Circuit Board, PCB) on surface or the surface of other substrate, by the methods such as reflow welding or the immersed solder circuit load technology of welding assembly in addition.
PCB (PrintedCircuitBoard), Chinese is printed circuit board, claim again printed circuit board (PCB), PC board, it is important electronic unit, being the supporter of electronic devices and components, is the supplier of electronic devices and components electrical connection, classifies according to the circuit number of plies: be divided into single sided board, dual platen and multilayer board, common multilayer board is generally 4 laminates or 6 laminates, and complicated multilayer board can reach tens layers.
Summary of the invention
Problem for the prior art existence, the purpose of this invention is to provide PCB and transport the control circuit of plugging into, it is simple in structure, laying is convenient, use is simple to operate and result of use good, realization is transmitted mainly for the production of the pcb board on line, the functions such as buffering, PCB transportation connection platform is connection and cushions one of two major equipments between equipment.
The technical solution used in the present invention is:
PCB transports the control circuit of plugging into, and comprises that core devices programmable logic controller (PLC) PLC, head end photoelectric sensor, end optoelectronic induction, warning, stepping motor and chain form; Programmable logic controller (PLC) PLC is by the information of the accurate inductor of photoelectricity that is received in PCB transportation connection platform head end and end and installs respectively, come the stall of control step motor, thereby the drive chain movement, with complete the PCB wiring board in transportation the function such as the transportation on connection platform and buffering.
Head end and the end of PCB transportation connection platform are installed respectively photoelectric sensor, and when the head end photoelectric sensor was sensed headend equipment and had the PCB wiring board to send, stepping motor drove chain and comes into operation, and guarantees that PCB carries smooth running; Whether the accurate inductor of end photoelectricity detects has rear end equipment to carry PCB wiring board in the past receiving, and when detecting when there is no rear end equipment, automatic pause is carried, and the system alarm system, reminds the staff.
Described stepping motor is characterized in that driving chain operation by stepping motor, and its speed is adjustable speed, and controls the transmission direction of carrying connection platform by the rotation direction of controlling motor, and it can be transmitted arbitrarily by both direction.
The present invention compared with prior art has the following advantages:
1. master controller is controlled by Delta PLC, and two ends all have the accurate induction of photoelectricity from beginning to end, have the I/O signaling interface, and guide rail width is adjustable, and steel framed structure is sturdy and durable, and can be connected with up and down equipment connection plate wiring the exclusive guideway aluminium section bar.
2. connection platform is widely used in pcb board transmission, buffering on the manufacturing line function such as plug into.It is connect and cushion one of two major equipments between equipment, can connect separately two equipment, also can segmentation or use in groups, it can the treatment technology parameter in the pcb board of specified specification.
Description of drawings
Accompanying drawing is schematic diagram of the present invention.
The specific embodiment
With reference to accompanying drawing, the technical solution used in the present invention is: PCB transports the control circuit of plugging into, and comprises that mainly core devices programmable logic controller (PLC) PLC, head end photoelectric sensor, end photoelectric sensor, warning, stepping motor and chain etc. partly form; Programmable logic controller (PLC) PLC is by the information of the accurate inductor of photoelectricity that is received in PCB transportation connection platform head end and end and installs respectively, come the stall of control step motor, thereby the drive chain movement, with complete the PCB wiring board in transportation the function such as the transportation on connection platform and buffering.
The accurate inductor of described photoelectricity is characterized in that at the head end of PCB transportation connection platform and end, the accurate inductor of photoelectricity being installed respectively, when the head end photoelectric sensor is sensed headend equipment and is had the PCB wiring board to send, stepping motor drives chain and comes into operation, and guarantees that PCB carries smooth running; Whether the accurate inductor of end photoelectricity detects has rear end equipment to carry PCB wiring board in the past receiving, and when detecting when there is no rear end equipment, automatic pause is carried, and the system alarm system, reminds the staff.
Described stepping motor is characterized in that driving chain operation by stepping motor, and its speed is adjustable speed, and controls the transmission direction of carrying connection platform by the rotation direction of controlling motor, and it can be transmitted arbitrarily by both direction.
