Description

Technical Field

[0001] The utility model relates to the technical field of assembly line control, in particular to a photovoltaic component assembly line control system. Background Art

[0002] The production of photovoltaic modules involves many production processes. Photovoltaic modules need to shuttle back and forth between various independent production machines. The existing conveyor line is the equipment used for photovoltaic module assembly line transmission. The transmission device drives the conveyor belt to move under the drive of the motor. The conveyor belt transmits the photovoltaic modules, which facilitates the production of photovoltaic module assembly line.

[0003] Existing production lines use direct communication via PLC or remote module I / O signals to control start, stop, and switching between first and second speeds. This results in cumbersome wiring, lengthy debugging, multiple locations, and high costs. Furthermore, when switching formats or changing the overall conveyor speed, the first and second speeds of each section of the production line must be adjusted individually, increasing the workload for equipment operators and the time required for line cutting. Furthermore, manual adjustments can easily lead to missed adjustments on some production line machines, impacting the initial film run after line cutting. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to propose a photovoltaic module assembly line control system to solve the problems of the existing technology, such as complicated wiring, long debugging time, occupying many points, high cost, and the entire production line being very cumbersome when switching formats or changing the overall conveying speed.

[0005] Based on the above-mentioned purpose, the utility model provides a photovoltaic module assembly line control system, including a core PLC; a switch, connected to the core PLC via a network cable; a touch screen, communicating with the core PLC by being connected to the switch; multiple H3U sub-control PLCs, communicating with the core PLC by being connected to the switch; an assembly line sub-control cabinet group, including multiple assembly line sub-control cabinets; each H3U sub-control PLC is connected to a assembly line sub-control cabinet group; the core PLC and the H3U sub-control PLC communicate via the Modbus TCP communication protocol; the H3U sub-control PLC and each of the assembly line sub-control cabinets in the assembly line sub-control cabinet group connected to it communicate via the Canlink communication protocol.

[0006] As a further improvement of the present application, a drive component is provided on the assembly line, and the assembly line sub-control cabinet 6 controls the operation of a section of the assembly line by controlling the action of the drive component.

[0007] As a further improvement of the present application, a Canlink terminal block is provided in the assembly line sub-control electrical cabinet, and the assembly line sub-control electrical cabinets in the same group are connected in series with each other through the Canlink communication protocol. Any assembly line sub-control electrical cabinet in the same group communicates with the H3U sub-control PLC through the Canlink communication protocol.

[0008] As a further improvement of the present application, the drive assembly includes a drive motor and / or a cylinder actuator barrel, and a frequency converter is provided in the assembly line sub-control cabinet. The frequency converter controls the operating speed of the drive motor, and the assembly line sub-control cabinet controls the extension and shortening of the cylinder actuator barrel.

[0009] As a further improvement of the present application, the inverter is provided with a Canlink terminal block, and the inverters of the assembly line sub-control cabinets in the same group are connected in series with each other through the Canlink communication protocol. The inverter of any one of the assembly line sub-control cabinets in the same group communicates with the H3U sub-control PLC through the Canlink communication protocol.

[0010] As a further improvement of the present application, the photovoltaic module assembly line control system also includes an MES system. The MES system communicates with the core PLC via the Modbus TCP protocol. The core PLC uploads the operating status to the MES system in real time and displays it.

[0011] The beneficial effects of the present invention are as follows: a core PLC drives several H3U sub-control PLCs via Modbus TCP, and the H3U sub-control PLCs extend the assembly line sub-control cabinets via CANLINK communication, thereby driving the entire assembly line, hundreds of workstations, or even thousands of workstations.

[0012] Canlink communication is used to control the start, stop and speed regulation of the production line, simplifying installation, reducing the use of unnecessary I / O points, and lowering equipment system costs.

[0013] The core PLC sends the control speed to the H3U sub-control PLC via Modbus TCP protocol communication. The H3U sub-control PLC then distributes the speed control word to the inverter of the assembly line sub-control cabinet via Canlink protocol communication, achieving rapid speed regulation, reducing the labor intensity of operation and maintenance personnel, and providing fast communication speed and no delay.

[0014] The H3U sub-control PLC reads the inverter operating status of a single-section conveyor line in real time and forwards the status to the core PLC. When the inverter has an abnormality, the system will promptly alarm and display the specific alarm line number and specific abnormal status code on the touch screen. When a general fault needs to be reset, simply click the reset button on the touch screen to achieve a remote one-touch reset. BRIEF DESCRIPTION OF THE DRAWINGS
