Description

Technical Field

[0001] This utility model relates to the field of automatic control technology, specifically to a control system and a string welding machine. Background Technology

[0002] A string welding machine is a device that uses a mechanical transmission mechanism to transport solar cells. It is mainly used for string welding of monocrystalline and polycrystalline solar cells in fully automatic crystalline silicon solar cell modules. It is suitable for string welding of crystalline silicon solar cells from 40mm×156mm to 156mm×156mm.

[0003] In existing technologies, the welding methods used in string welding machines are divided into non-contact welding methods and contact welding methods. Non-contact welding methods include hot air welding, infrared lamp welding, and electromagnetic induction welding, while contact welding methods include soldering. In non-contact welding, infrared lamp welding completes the welding work by radiating heat to the solder joint using infrared rays of an appropriate wavelength. The emission of infrared rays requires an infrared lamp, and the wavelength of the infrared rays needs to be controlled by a control system. The control system specifically consists of a controller and a silicon controlled rectifier (SCR) module. The controller and the SCR module are electrically connected via wires, and the SCR module is in turn electrically connected to the infrared lamp, thus enabling the controller to control the wavelength of the infrared rays emitted by the infrared lamp through the SCR module.

[0004] However, in existing control systems, because the control components are far from the thyristor module, the control components need to be electrically connected to the thyristor module via wires. Therefore, the control components send analog control signals to the thyristor module. The analog control signals need to be protected against interference by adding anti-interference filtering circuits, which will cause delays and distortions in the control signals, resulting in low real-time performance and stability of the control system.

[0032] The technical solution provided by this utility model has the following advantages:

[0033] 1. The control system provided by this utility model includes a housing, a connector, and a control structure. The housing has a receiving cavity and several spaced-apart mounting cavities. The connector is disposed between the receiving cavity and all the mounting cavities. The control structure includes a controller and several thyristor modules. The controller is disposed in the receiving cavity, and any thyristor module is disposed in a mounting cavity. Both the controller and the thyristor modules are electrically connected to the connector, so as to electrically connect the controller and the thyristor modules through the connector. The thyristor module has a control circuit. When the thyristor module is electrically connected to the connector, the control circuit of the thyristor module is electrically connected to the controller through the connector.

[0034] The control system of this structure utilizes connectors and a control structure housed within a casing. The casing has a receiving cavity and several spaced-apart mounting cavities.

The controller and all SCR modules are electrically connected to the connectors, allowing the connectors to electrically connect the controller and all the SCR modules. Furthermore, each SCR module has a control circuit.

Therefore, the controller can directly send digital control signals to the SCR modules without requiring additional anti-interference filtering circuits to ensure the digital control signals are not interfered with. This prevents delays and distortions in the digital control signals and improves the real-time performance and stability of the control system.

And / or, the thyristor module has a second port corresponding to the second interface, which is plugged into the second interface to electrically connect the thyristor module and the connector.

The thyristor module also has a high-voltage power supply interface electrically connected to the control circuit, used to connect a high-voltage power supply to power the control circuit and the infrared lamp.

[0036] The control system of this structure utilizes a first interface and several second interfaces on the connector. The first interface is specifically located within a receiving cavity and, when the control component is installed in the receiving cavity, can electrically connect to the control component, thus achieving electrical connection between the control component and the connector. Each second interface is located within a mounting cavity, and, when a thyristor module is installed in a mounting cavity, each second interface in the mounting cavity can electrically connect to the corresponding thyristor module, thus achieving electrical connection between the thyristor module and the connector. This allows the connector to electrically connect the control component and all thyristor modules. Through the first port on the control component and the second ports on the thyristor modules, when the control component is installed in the receiving cavity, the first port on the control component can be plugged into the first interface on the connector, thereby achieving electrical connection between the control component and the connector. Similarly, when the thyristor module is installed in the mounting cavity, the second port on the thyristor module can be plugged into the second interface on the connector, thereby achieving electrical connection between the thyristor module and the connector. The third interface and high-voltage power interface are both electrically connected to the control circuit on the SCR module. The third interface can be electrically connected to the infrared lamp, and the high-voltage power interface can be powered on. This allows the infrared lamp to receive power through the control circuit and the third interface, enabling it to emit light and generate heat. The controller can then control the intensity of the infrared lamp's light through the connector and the control circuit to regulate the heat generated by the infrared lamp.

[0037] 3. The control system provided by this utility model includes an output optocoupler and a thyristor in the control circuit. The signal output terminal of the output optocoupler is used to receive the control signal from the second interface, and the signal output terminal of the output optocoupler is used to control the conduction state of the thyristor according to the control signal. The signal output terminal of the output optocoupler includes a first pin and a second pin. The second pin is used to receive the control signal from the second interface, and the first pin is grounded through the optocoupler current-limiting resistor. Inside the output optocoupler, the second pin is connected to the first pin through a light-emitting diode. The signal output terminal of the output optocoupler includes a third pin and a fourth pin. The third pin is connected to the first node through a trigger current-limiting resistor, and the fourth pin is connected to the second node through a current-discharging resistor. The first node and the second node are connected through the thyristor, and the voltage of the fourth pin is used to control the conduction state of the thyristor. Inside the output optocoupler, the third pin is connected to the fourth pin through a light receiver. The first node is connected to the second terminal of the high-voltage power interface through a fuse resistor. The second node is connected to the first terminal of the third interface, and the second terminal of the third interface is connected to the first terminal of the high-voltage power interface. The thyristor module also includes an absorption resistor and an absorption capacitor. The first node is connected to the second node in sequence through the absorption resistor and the absorption capacitor.

[0038] The control system of this structure includes an output optocoupler and a thyristor in the control circuit. The signal output terminal of the output optocoupler can receive the control signal from the second interface. This control signal is transmitted by the control component to the second interface on the connector through the first interface. It is used to control the luminous intensity of the infrared lamp. In addition, the signal output terminal of the output optocoupler can control the conduction state of the thyristor according to the control signal. That is, when the control component sends a control signal to the thyristor module through the first interface, the output optocoupler can conduct the thyristor to enable the control circuit to operate normally. When there is no control signal, the thyristor is in a non-conducting state, and the control circuit cannot operate normally. The output optocoupler is configured with a first pin and a second pin. The second pin receives the control signal from the second interface, allowing the control signal to be input into the control circuit. The first pin is grounded through the optocoupler's current-limiting resistor to ensure circuit integrity. Internally, the second pin is connected to the first pin via a light-emitting diode (LED). When the control signal is input to the optocoupler through the second pin, a voltage is generated between the first and second pins, causing the LED to conduct and emit light. The light receiver of the optocoupler then conducts upon receiving the light signal emitted by the LED, thus putting the entire control circuit into a conducting state.The output optocoupler is configured with a third and a fourth pin. The third pin is connected to the first node via a trigger current-limiting resistor, and the fourth pin is connected to the second node via a current-discharging resistor. The first and second nodes are connected via a thyristor. This ensures that only a small portion of the high-voltage input at the high-voltage power supply interface forms a loop through the output optocoupler. When the control signal is input into the control circuit, the voltage at the fourth pin controls the conduction of the thyristor, allowing the high-voltage input at the high-voltage power supply interface to flow through the thyristor, thereby increasing the current intensity of the control circuit. A photodetector is located inside the output optocoupler, positioned between the third and fourth pins, connecting the third pin to the fourth pin. This allows the third and fourth pins to be connected within the control signal input / output optocoupler, illuminating the LED. The circuit will only conduct when the voltage is high. A fuse resistor is installed between the first node and the high-voltage power interface to ensure the control circuit remains operational when high voltage is applied, thus improving the overall stability of the control circuit. By connecting the second node to the first end of the third interface and connecting the second end of the third interface to the first end of the high-voltage power interface, a loop is formed between the third interface and the high-voltage power interface, enabling the third interface to supply power to the infrared lamp. An absorption resistor and absorption capacitor are installed in the thyristor module, and the first node is sequentially connected to the second node through these resistors and capacitors. When the voltage at the high-voltage power interface is unstable, the absorption resistor and capacitor absorb the unstable voltage until the voltage in the circuit stabilizes, thereby improving the stability of the control circuit.

When the control component is installed in the accommodating cavity, the first limiting part is adapted to abut against the control component to limit the control component; and / or, a second limiting part is provided at the bottom of the mounting cavity. When the thyristor module is installed in the mounting cavity, the second limiting part is adapted to abut against the thyristor module to limit the thyristor module.

The control system also includes a locking assembly, which includes a first locking member and a second locking member. When the control component is installed in place, the first locking member is adapted to pass through the first and second connecting parts to connect the control component and the housing; when the thyristor module is installed in place, the second locking member is adapted to pass through the first and third connecting parts to connect the thyristor module and the housing. Several fans are installed inside the housing. The air intake of several fans points towards the connector, and the air outlet of several fans is located on the outer wall of the housing. The fans are used to exhaust hot air from inside the housing.

[0040] The control system of this structure has a first limiting part at the bottom of the accommodating cavity and a second limiting part at the bottom of the mounting cavity. In this embodiment, the first limiting part and the second limiting part are respectively a first limiting groove and a second limiting groove. When the control component is installed in the accommodating cavity, the first limiting part can abut against the control component to limit the control component and ensure that the control component can be accurately installed in the accommodating cavity.

The thyristor module 32 has a control circuit 4. When the thyristor module 32 is electrically connected to the connector 2, the control circuit 4 of the thyristor module 32 is electrically connected to the controller 31 through the connector 2.

[0058] The control system described above utilizes a connector 2 and a control structure 3 housed within the housing 1.

The control circuit 4 enables each SCR module 32 to be electrically connected to the connector 2 and the control unit 31 after the SCR module 32 is electrically connected to the connector 2 and the control unit 31 through the control circuit 4. This allows the SCR module 32 to be directly electrically connected to the control unit 31 through the control circuit 4 and the connector 2, without the need for a wire. Therefore, the control unit 31 can directly send digital control signals to the SCR module 32 without the need for an additional anti-interference filter circuit to ensure that the digital control signals are not interfered with. This prevents delays and distortions in the digital control signals and improves the real-time performance and stability of the control system.

The signal output terminal of the output optocoupler 41 can receive the control signal from the second interface 22. This control signal is transmitted by the control unit 31 to the second interface 22 on the connector 2 through the first interface 21. It is used to control the luminous intensity of the infrared lamp. In addition, the signal output terminal of the output optocoupler 41 can control the conduction state of the thyristor 42 according to the control signal. That is, when the control unit 31 sends the control signal to the thyristor module 32 through the first interface 21, the output optocoupler 41 can conduct the thyristor 42 to enable the control circuit 4 to operate normally. When there is no control signal, the thyristor 42 is in a non-conducting state, and the control circuit 4 cannot operate normally.

[0067] The control system provided in this embodiment, such as Figure 4 As shown, the signal output terminal of the output optocoupler 41 includes a first pin 411 and a second pin 412.

Inside the output optocoupler 41, the second pin 412 is connected to the first pin 411 through a light-emitting diode 415.

[0068] The control system described above includes a first pin 411 and a second pin 412 at the signal output terminal of the output optocoupler 41. The second pin 412 can receive the control signal from the second interface 22 so that the control signal can be input into the control circuit 4. The first pin 411 is grounded through the optocoupler current-limiting resistor 417 to ensure the integrity of the circuit. Inside the output optocoupler 41, the second pin 412 is connected to the first pin 411 through a light-emitting diode 415. When the control signal is input into the output optocoupler 41 through the second pin 412, a voltage is generated between the first pin 411 and the second pin 412, which causes the light-emitting diode 415 to conduct and emit light. The light receiver 416 inside the output optocoupler 41 conducts after receiving the light signal emitted by the light-emitting diode 415, thereby controlling the control circuit 4 to be in a conducting state.

[0069] The control system provided in this embodiment, such as Figure 4As shown, the signal output terminal of the output optocoupler 41 includes a third pin 413 and a fourth pin 414. The third pin 413 is connected to the first node 46 through a trigger current-limiting resistor 43, and the fourth pin 414 is connected to the second node 47 through a current-discharging resistor 44. The first node 46 and the second node 47 are connected through a silicon controlled rectifier (SCR) 42. The voltage of the fourth pin 414 is used to control the conduction state of the SCR 42. Inside the output optocoupler 41, the third pin 413 is connected to the fourth pin 414 through a light receiver 416. The first node 46 is connected to the second terminal of the high-voltage power interface 323 through a fuse resistor 45. The second node 47 is connected to the first terminal of the third interface 322, and the second terminal of the third interface 322 is connected to the first terminal of the high-voltage power interface 323. The SCR module 32 also includes an absorption resistor 48 and an absorption capacitor 49. The first node 46 is connected to the second node 47 in sequence through the absorption resistor 48 and the absorption capacitor 49.

[0070] The control system described above includes a third pin 413 and a fourth pin 414 at the signal output terminal of the output optocoupler 41. The third pin 413 is connected to the first node 46 through a trigger current-limiting resistor 43, and the fourth pin 414 is connected to the second node 47 through a current-discharging resistor 44. The first node 46 and the second node 47 are connected through a thyristor 42. In this way, only a small portion of the high-voltage electricity input at the high-voltage power interface 323 forms a loop through the output optocoupler 41. After the control signal is input into the control circuit 4, the voltage of the fourth pin 414 can control the conduction of the thyristor 42, thereby allowing the high-voltage electricity input at the high-voltage power interface 323 to flow through the thyristor 42, thus increasing the current intensity of the control circuit 4.

[0071] By using a light receiver 416 located inside the output optocoupler 41, between the third pin 413 and the fourth pin 414, the third pin 413 is connected to the fourth pin 414 through the light receiver 416. This ensures that the third pin 413 and the fourth pin 414 are only turned on when the control signal is input into the output optocoupler 41 and the light-emitting diode 415 is illuminated.

[0072] By setting a fuse resistor 45 between the first node 46 and the high-voltage power interface 323, the fuse resistor 45 can ensure the conduction of the control circuit 4 according to the voltage strength when the high-voltage power interface 323 is connected to high voltage, thereby improving the overall stability of the control circuit 4.

[0073] By setting the second node 47 to the first end of the third interface 322 and setting the second end of the third interface 322 to the first end of the high-voltage power interface 323, the third interface 322 can form a loop with the high-voltage power interface 323, thereby enabling the third interface 322 to provide power to the infrared lamp.

[0074] By using the absorption resistor 48 and absorption capacitor 49 in the thyristor module 32, the first node 46 is connected to the second node 47 in sequence through the absorption resistor 48 and absorption capacitor 49. When the voltage at the high-voltage power supply interface 323 is unstable, the absorption resistor 48 and absorption capacitor 49 can absorb the unstable voltage until the voltage in the circuit is stable. This helps to improve the stability of the control circuit 4.

The air intake end of the plurality of fans 5 points to the connector 2, and the air outlet end of the plurality of fans 5 is located on the outer wall of the housing 1.
