Background
In the production process of the solar cell module, the lamination process is one of the key processes, and the main process is that after toughened glass, EVA adhesive films, cell sheets, EVA adhesive films, glass fibers and back plates are placed in a lamination mode, the EVA adhesive films are melted through vacuum hot pressing, and then the cell sheets, the glass and the back plates are bonded together, and then cooled, so that the photovoltaic module is obtained.
In the above process, the heating plate needs to be maintained in a high temperature state, typically 150 ℃. To maintain the temperature of the heating plate, the heating plate is typically fitted with a heating system. The heating systems currently in main stream are divided into oil heating systems and electric heating systems. For the oil heating system, a heat conducting oil flow passage is formed in the heating plate, and the heated heat conducting oil in the oil furnace circularly flows in the heat conducting oil flow passage in the heating plate, so that the heating of the heating plate is realized. The heating mode is mature in technology, but the heat dissipation of an external pipeline is serious in the oil heating process, and the oil furnace has the problems of oil leakage, oil injection and the like, so that personal and property losses are easily caused once accidents occur, and the oil furnace is gradually replaced by an electric heating system in recent years. The electric heating system has the characteristics of accurate temperature adjustment, no external component heat dissipation, automatic cutting after power failure and the like, and has great advantages in energy consumption and safety. The prior electric heating structure is characterized in that deep holes are formed in an electric heating plate, and heat pipes are inserted into the deep holes to form a heating system, and the main problem of the structure is that the heat pipes are densely arranged to ensure the uniformity of heating temperature, and accordingly, the manufacturing cost is high. Therefore, the industry is improved, a hot plate is adopted to replace a heat pipe to manufacture a hot plate type heating system, the main structure of the hot plate type heating system is that nickel-chromium alloy is etched to form a heating loop, high-temperature resistant insulating rubber or insulating mica sheets are used for insulating and packaging to form the heating plate, and an aluminum plate is additionally arranged on the outer side of the hot plate type heating system to play a role in fixing and supporting. The heating plates are tightly attached to the heating plate to realize heating, so that the system has better heating stability and better heating uniformity. Through the use, the hot plate type heating system is found to have the following technical problems that a heating loop formed by etching nickel-chromium alloy is easy to cause heating aging and then open circuit to cause the heating plate to fail in the long-term use process of the machine. If a certain hot plate fails in the hot pressing process, the heating temperature is low, so that the temperature of the heating plate is uneven to influence the lamination effect of the component, and the component is scrapped to cause economic loss when serious. Meanwhile, after the heating plate fails, the machine is stopped for maintenance, so that the economic loss caused by the productivity of enterprises is reduced.

In order to enable maintenance personnel to know the specific heating plate with faults, a current detection device is arranged for each standby heating loop, and when a certain standby heating loop with the heating loop with faults is conducted, a prompt is sent to a control system to mark the heating plate with faults. The method of the present invention will now be described in detail by way of example with respect to the provision of a backup heating circuit.
The method of the present invention may be implemented using a hot plate heating system as follows.
As shown in fig. 1-4, a hot plate heating system for a photovoltaic laminator is constructed in accordance with an embodiment of the invention, including at least one heating plate. The heating plate body is internally provided with at least one heating unit, each heating unit is at least provided with a heating loop A and a heating loop B, each heating unit is provided with a heating control unit, each heating control unit comprises an under-current relay, a power relay, a solid state relay and a temperature sensor, the heating loops A and B are respectively packaged on the heating plate body in an insulating way by high-temperature resistant insulating rubber or insulating mica sheets, two ends of the heating loops A and B are respectively joint ends, one end joint of each heating loop A and one end joint of each heating loop B are respectively commonly called a joint C, the other end joint of each heating loop A is called a joint A, the other end joint of each heating loop B is called a joint B, the joints A and the joints B are not communicated and are not conducted, and the joints C are used for communicating with a zero line. The joint A of the heating loop A is connected with the output end of the solid-state relay through a normally open point of the power relay, the joint B of the heating loop B is connected with one end of the undercurrent detection relay through a normally closed point of the power relay, the other end of the undercurrent detection relay is electrically connected with the output end of the solid-state relay, and the power supply connecting end of the solid-state relay is communicated with any one of alternating current 380v power supplies. One end of the power relay is in power supply communication with the heating plate in the alternating current 380V power supply, and the other end of the power relay is communicated with the zero line through a normally open point of the undercurrent detection relay. The temperature sensor is connected with the input end of the controller through an electric signal, and the input end of the solid state relay is electrically communicated with the output end of the controller.
The working process and the control method are as follows: as shown in fig. 1; the controller monitors the temperature of the heating plate in real time through the temperature sensor, sends on and off commands to the solid state relay, and sends out the on and off commands to the solid state relay when the heating plate needs to be heatedWhen the solid state relay is switched on, the current of the alternating current 380v power supply passes through the solid state relay, the normally closed point of the power relay, the connector B, the heating loop B, the connector C and the zero line to form a working loop, which is called as the working loop B for convenience of description, the heating loop B heats, and the temperature of the corresponding heating plate rises. When the temperature sensor detects that the heating plate does not need to be heated, a cutting-off command is sent to the solid state relay, the solid state relay is cut off, the working loop B is disconnected, no current passes through the heating loop B, and the heating plate does not generate heat.When (when)When the heating loop B normally works and has current to heat, the normally open point of the power relay for controlling the heating loop A is not closed, the heating loop A does not have current to pass, and the heating loop A does not work and does not heat; in the process of electrifying the working loop B, the current always passes through the undercurrent detection relay, and the normally open point of the undercurrent detection relay controlled by the undercurrent detection relay is in an off state. The above state is a normal operation. If no current passes through the undercurrent detection relay when the heating circuit B breaks down and is broken, no current passes through the working circuit B, the undercurrent detection relay is controlled to be normally open, the power relay is powered on to form a circuit through the power relay by alternating 380V current, the power relay is controlled to be normally open, the normally open point of the power relay is closed, the current of an alternating 380V power supply passes through the solid-state relay, the normally open point of the closed power relay, the connector A, the heating circuit A, the connector C and the zero line to form the working circuit A, the heating sheet heats to realize the heating function, when the temperature detection sensor detects that heating is not needed, the controller controls the solid-state relay to be cut off, the working circuit A is disconnected, the heating circuit A is not powered on, and the state is shown in the figure 2. By adopting the technical scheme, two heating loops are arranged, one heating loop is an in-use heating loop, the other heating loop is a standby heating loop, when the in-use heating loop fails, the system is automatically switched to work of the standby heating loop, the service life of the heating sheet is effectively prolonged, and the equipment has a maintenance period, so that the failed loop can be found out in the maintenance process and can be replaced in time, the processing of the laminating machine is not influenced, and the productivity of the laminating machine is ensured. The controller typically employs a PLC.

The current detection module can be arranged independently, the current detection module can also be arranged in the controller, when the current detection module is arranged independently, each current sensor is electrically connected with the input end of the current detection module, the output end of the current detection module is electrically connected with the input end of the controller, when the heating circuit B works, the heating circuit A does not work because the normally open point of the power relay is in an open state, the current sensor does not pass through, when the heating circuit B is open, the normally open point of the power relay is controlled by the power relay to be closed, the heating circuit A is electrified, at the moment, the current sensor passes through, the current detection module processes the detected current signal and then sends fault information to the controller, the controller records the position information and fault information of the heating plate or/and sends fault alarm information to prompt according to the position of the current sensor, so that the heating circuit of which heating plate is particularly in the actual heating process is switched, the damaged heating circuit is maintained in the production gap, or the heating circuit A is continuously used along with the continuous use of the heating plate, if the heating circuit A is aged, the current sensor is changed into the non-current state, the current state is also sent to the controller to send the fault information to the controller, and the controller can stop the heating plate is required to be replaced.
