Description

Technical Field

[0001] The utility model relates to the field of infrared heating control, in particular to an infrared heating control system and a drying oven. Background Art

[0002] The oven is one of the equipment used in the drying process of the coating process. Wet coating requires the foil to be coated with positive electrode materials and negative electrode materials. The solvent of the negative electrode material is water, while the solvent of the positive electrode material contains N-methylpyrrolidone (NMP). After drying, it becomes a gas containing NMP. The ignition point of gas NMP is 90°C. It is an explosive chemical substance. When its concentration exceeds 10%, it is prone to spontaneous combustion and is also corrosive.

[0003] The traditional oven drying process uses a circulating air system to dry the electrode, and the drying efficiency is improved by increasing the drying air volume. If the drying air volume is too large, it is easy to cause the electrode to vibrate significantly. For this reason, the existing technology introduces infrared heating technology to heat the electrode to improve the drying speed and drying quality.

[0004] However, in order to prevent the NMP gas in the oven from corroding the infrared heating components and the internal high temperature from igniting the NMP gas, the existing infrared heating devices usually adopt a closed structure. Safety problems may occur when any heating point of the device is exposed to NMP gas with a concentration greater than 10%. The temperature detection scheme of the infrared heating device in the prior art usually only detects the surface temperature of the electrode, and cannot track the local temperature point of the infrared heating device in time, which is prone to safety hazards.

DETAILED DESCRIPTION

[0042] The embodiment of the utility model discloses an infrared heating control system and an oven, which are used to solve the technical problem that the temperature detection scheme of the infrared heating device in the prior art usually only detects the surface temperature of the electrode, cannot track the local temperature point of the infrared heating device in time, and is prone to safety hazards.

[0043] See also Figure 1 , a logical structure block diagram of an infrared heating control system provided in an embodiment of the utility model.

[0044] The embodiment of the utility model provides an infrared heating control system, including a control module 1, a plurality of explosion-proof actuators, at least one set of first detection components 31 and at least one set of second detection components 32;

[0045] The first detection component 31 is installed inside the infrared heating device 2, and is used to detect the internal temperature of the infrared heating device 2 and send it to the control module 1;

[0046] The second detection component 32 is installed outside the infrared heating device 2, and is used to detect the external temperature of the infrared heating device 2 and send it to the control module 1;

[0047] The control module 1 is electrically connected to each of the explosion-proof actuator ends, and is used to regulate at least one of the explosion-proof actuator ends according to the internal temperature and / or the external temperature.

[0048] In this embodiment, the first detection component 31 is installed inside the infrared heating device 2, and the second detection component 32 is installed outside the infrared heating device 2, respectively, for real-time detection of the internal temperature and the external temperature of the infrared heating device 2 and sending them to the control module 1. The control module 1 is electrically connected to the explosion-proof execution end, the first detection component 31, and the second detection component 32, respectively, and receives temperature signals such as temperature values ​​sent from each component, and determines whether the temperature exceeds a preset threshold value, and sends a corresponding control signal to drive the explosion-proof execution end to perform an action, thereby achieving safety adjustment of the infrared heating device 2 and avoiding safety problems.

[0049] In order to realize all-round temperature monitoring of the infrared heating device 2, the first detection component 31 and the second detection component 32 can be set in multiple groups, and the two are staggered on both sides of the infrared heating device 2 to respectively detect the temperature of multiple points of the infrared heating device 2. The explosion-proof execution end may include various types of components, such as an air guide component 41, an infrared power supply 42, and a circulating air component 432, etc., which are electrically connected to the control end of each component through the control end, and send instructions to control each component to perform opening and closing actions when the temperature is abnormal.

[0050] For example, the control module 1 in this embodiment can select a PLC control module 1 to control the opening and closing of the explosion-proof execution end by means of electrical signals or logic control signals. For example, if the internal temperature or the external temperature is greater than a certain threshold, in order to prevent the risk of explosion of the infrared heating component 21, the control module 1 needs to call the air guide component 41 and the infrared power supply 42 to cool down at the same time, and can open the air guide component 41 to exhaust the inside of the infrared heating component 21 by sending an electrical signal such as a high level, and at the same time send an electrical signal to the infrared power supply 42 such as continuously sending a low level for a certain period of time, so as to gradually reduce the heating temperature of the infrared heating component 21.

[0051] In addition, the control module 1 can control the power regulator by constant power control, and the power regulator sends a control signal to the current sensor, and the current sensor sends an AC contactor to the infrared heating component 21 to switch the heating function. Among them, two or more infrared heating plates can be provided in the same infrared heating component 21 at the same time, and the thickness of the infrared heating plate can be different to adapt to different electrode baking requirements.

[0052] In one example of the present utility model, the first detection component 31 is a patch temperature sensor, and the second detection component 32 is a thermocouple temperature sensor;

[0053] The first detection component 31 and the second detection component 32 are respectively installed on both sides of the infrared heating device 2 and are arranged alternately, so as to accurately collect data and feed it back to the control module for analysis and processing, thereby improving control sensitivity.

[0054] In this embodiment, since the infrared heating component 21, such as an infrared heating plate, usually adopts a closed structure, drilling can easily destroy its structural stability, resulting in cracking at high temperatures. For this reason, the first detection component 31 is used as a component for detecting the internal temperature of the infrared heating device 2, that is, the surface temperature of the infrared heating component 21. A patch temperature sensor can be selected. The patch temperature sensor is attached to the surface of the object by attaching or other fixing methods to achieve a more ideal temperature measurement effect. The patch temperature sensor has a large contact area with the object to be measured, and the contact is close. It has high temperature measurement accuracy, fast response speed, and small size, which is convenient for fixed installation. Specifically, the first detection component 31 can be installed on the inner surface of the infrared heating device 2 or the outer surface of the infrared heating component 21.

[0055] As for the second detection component 32, it is installed on the outside of the infrared heating device 2 to detect the external temperature of the infrared heating device 2. If a large-scale detection of the infrared heating device 2 is required, a more common thermocouple temperature sensor can be selected. It has the characteristics of stable performance, large temperature measurement range, and long-distance signal transmission. It also has a simple structure and is easy to use. It can directly convert thermal energy into electrical signals and output DC voltage signals, so that the control module 1 can quickly receive the electrical signals corresponding to the external temperature for judgment and processing.

[0056] In another example of the present invention, the infrared heating control system may further include a temperature control component 33;

[0057] The temperature control component 33 is electrically connected to the first detection component 31 , the second detection component 32 and the control module 1 , respectively, and is used to pre-process the internal temperature and / or the external temperature and forward them to the control module 1 .

[0058] Since the requirements for the types of the first detection component 31 and the second detection component 32 are different when they are selected, and the applicable scenarios are also different, the electrical signals uploaded to the control module 1 may also be different. In order to unify the data dimension and format and improve the processing efficiency of the control module 1, a temperature control component 33 can be provided before the control module 1, which receives the internal temperature and external temperature detected by the first detection component 31 and the second detection component 32 and performs pre-processing, and then forwards them to the control module 1 for subsequent processing.

[0059] The preprocessing operation may include but is not limited to operations such as sorting the multiple internal temperatures and the multiple external temperatures, converting them to a unified dimension, converting them to a unified format, etc.

[0060] In one example of the present utility model, the infrared heating device 2 is further provided with at least one air guide component 41;

[0061] The air guide component 41 is used to perform ventilation on the infrared heating device 2 when it is turned on.

[0062] In this embodiment, at least one air guide component 41 can be further provided on the infrared heating device 2. The air guide component 41 can be installed at different positions on the surface of the infrared heating device 2. Each air guide component 41 can be respectively connected to the air guide control end, and communicated with the control module 1 through the air guide control end. The air guide control end responds to the control signal sent by the control module 1 to turn on the air guide component 41. When turned on, the air guide component 41 connects the heating layer in the infrared heating component 21 and the external space.

[0063] The types of the air guide assembly 41 may include but are not limited to a one-way air guide valve and an air guide pipe, etc. The one-way air guide valve includes an inward air injection valve and an outward air extraction valve, and by opening the two one-way air guide valves at the same time, the external low-temperature gas is injected and the internal high-temperature gas is extracted and discharged quickly, thereby realizing the rapid heat exchange of the infrared heating assembly 21.

[0064] Further, the infrared heating device 2 is installed in the oven;

[0065] The explosion-proof execution end includes an air guide control end, an infrared power supply 42 and a circulating air component 432;

[0066] The air guide control end is electrically connected to the air guide component 41, and is used to drive the air guide component 41 to perform an opening and closing action;

[0067] The infrared power source 42 is electrically connected to the infrared heating component 21 in the infrared heating device 2;

[0068] The circulating air component 432 is embedded in the oven.

[0069] In this embodiment, the explosion-proof execution end may include an air guide control end, an infrared power supply 42 and a circulating air component 432. The control module 1 may be judged according to the actual internal and external temperature conditions to select a suitable explosion-proof execution end to perform safety control on the infrared heating device. The explosion-proof execution end may select one of them for use or a combination of multiple uses. Among them, the air guide control end is electrically connected to the air guide component 41 and installed on the outer shell of the infrared heating device 2, and the air guide component 41 is driven to open and close to realize the internal and external heat exchange of the infrared heating component 21. The infrared power supply 42 is electrically connected to the infrared heating component 21 in the infrared heating component 21 to provide electric energy for the infrared heating component 21 to generate heat. The oven also belongs to a closed environment when heating. If the temperature of the infrared heating component 21 is too high or the concentration of NMP gas emitted by the pole piece is too high, in order to prevent the infrared heating component 21 from being affected by the NMP gas and causing safety problems, the circulating air component 432 installed on the side wall of the oven can be used to exhaust the gas inside the oven to reduce the concentration of NMP inside the oven.

[0070] Furthermore, the control module 1 includes a first comparison circuit and a signal sending circuit which are electrically connected;

[0071] The first comparison circuit is used to compare the internal temperature with a preset first internal temperature threshold;

[0072] The signal sending circuit is used to send an open signal to the gas guide control end to turn on the gas guide component 41 when it determines that the internal temperature is higher than or equal to the first internal temperature threshold, until the internal temperature is lower than the preset second internal temperature threshold, and send a close signal to the gas guide control end to close the gas guide component 41.

[0073] In this embodiment, the control module 1 includes an electrically connected first comparison circuit and a signal sending circuit. After the control module 1 receives the internal temperature, it is sent to the first comparison circuit such as a temperature comparison circuit. The first comparison circuit uses the received internal temperature and a preset first internal temperature threshold to compare and determine whether the internal temperature is higher than or equal to the first internal temperature threshold. If so, it indicates that the internal temperature of the infrared heating device 2 is abnormally high at this time. In order to prevent the safety risk of explosion, the signal sending circuit is triggered by the first comparison circuit to generate a corresponding start signal and send the start signal to the air guide control end to turn on the air guide component 41. At this time, the air guide component 41 can connect the outside and the inside of the infrared heating device 2 for heat exchange. If there are multiple air guide components 41, gas injection and extraction can be performed respectively through the air guide components 41, so that the hot gas can be quickly and alternately discharged to cool the infrared heating device 2.

[0074] At the same time, the first detection component 31 still detects the internal temperature periodically or in real time. When the first comparison circuit determines that the internal temperature is lower than the preset second internal temperature threshold, it indicates that the infrared heating temperature is in a normal state. At this time, the first comparison circuit triggers the signal sending circuit to generate a shutdown signal and sends it to the air guide control terminal to close the air guide component 41. Among them, the first internal temperature threshold is higher than the second internal temperature threshold.

[0075] In addition, the gas guide control end can also be a signal-triggered module, which triggers the gas guide component 41 to open when an opening signal is received, and closes the gas guide component 41 when no opening signal is received.

[0076] Optionally, the control module 1 further includes a second comparison circuit electrically connected to the signal sending circuit;

[0077] The second comparison circuit is used to compare the external temperature with a preset first external temperature threshold;

[0078] The signal sending circuit is also used to send a temperature control signal to the infrared power supply 42 to reduce the heating temperature of the infrared heating component 21 when it is determined that the external temperature is higher than or equal to the first external temperature threshold, and to send a ventilation adjustment signal to the air guide control end to increase the ventilation speed until the external temperature is lower than the preset second external temperature threshold.

[0079] In this embodiment, the external temperature sent by the second detection component 32 is compared with the first external temperature threshold in real time by the second comparison circuit. If the second comparison circuit determines that the external temperature is higher than or equal to the preset first external temperature threshold, it indicates that the internal temperature of the infrared heating device 2 has risen to a certain extent, and the exhaust of the air guide component 41 alone cannot effectively reduce the temperature. At this time, in order to improve the cooling effect, the second comparison circuit can be used to trigger the signal sending circuit, generate a temperature control signal and send it to the infrared power supply 42, and generate a ventilation adjustment signal and send it to the air guide control end to reduce the external temperature. Specifically, when the temperature control signal is sent to the infrared power supply 42 under control, the infrared power supply 42 can respond to the temperature control signal and reduce its power output according to a certain gradient within the time period of receiving the temperature control signal to reduce the heating temperature of the infrared heating component 21. At the same time, the air guide control end can increase the ventilation speed by opening more air guide components 41 at the same time or adjusting the opening amplitude of the air guide component 41, so that the external temperature is reduced to a value lower than the preset second external temperature threshold. Among them, the second external temperature threshold is less than the first external temperature threshold.

[0080] In addition, after the outside temperature drops below the second outside temperature threshold, the control module 1 can interrupt the sending of the temperature control signal and the ventilation adjustment signal through the signal sending circuit to restore the infrared power supply 42 and the air guide component 41 to a normal working state. Alternatively, another signal can be sent to restore the infrared power supply 42 and the air guide component 41 to a normal working state. The embodiment of the utility model does not limit this state recovery method.

[0081] It should be noted that the first comparison circuit and the second comparison circuit refer to circuit structures for temperature comparison, which can be implemented by circuit structures composed of two comparators. For example, for the first comparison circuit, the comparison between the internal temperature and the first internal temperature threshold, and the comparison between the internal temperature and the second internal temperature threshold can be implemented by two comparators, respectively, and the output signal of the comparator can be used to control the signal generation of the subsequent signal sending circuit.

[0082] Furthermore, a gas concentration detection component 431 electrically connected to the control module 1 is installed in the oven, and the control module 1 also includes a concentration comparison circuit electrically connected to the signal sending circuit;

[0083] The gas concentration detection component 431 is used to detect the specific gas concentration inside the oven and upload it to the control module 1;

[0084] The concentration comparison circuit is used to compare the specific gas concentration with a preset first concentration threshold;

[0085] The signal sending circuit is used to determine whether the concentration of the specific gas exceeds the first concentration threshold, and send a convection adjustment signal to the circulating air component 432 to increase the convection speed until the concentration of the specific gas is lower than a preset second concentration threshold.

[0086] In the present embodiment, the oven may also be provided with a gas concentration detection component 431 electrically connected to the control module 1, so as to detect the specific gas concentration in the oven in real time. The specific gas may include NMP gas or other types of gas. After the concentration comparison circuit compares the specific gas concentration and the preset first concentration threshold, if it is determined that the specific gas concentration exceeds the preset first concentration threshold such as 10% concentration, it indicates that there is a risk of NMP gas causing the infrared heating component 21 to explode, and the signal can be triggered to send the circuit to generate a convection adjustment signal and send it to the circulating wind component 432. The circulating wind component 432 maintains a high convection speed for gas extraction and gas injection during the time period when the convection adjustment signal is received, so as to achieve rapid air exchange, thereby effectively reducing the NMP concentration value inside the oven. Until the specific gas concentration is lower than the preset second concentration threshold, the transmission of the convection adjustment signal is interrupted at this time, so that the circulating wind component 432 maintains a normal convection speed for gas exchange.

[0087] Among them, after the gas concentration detection component detects the specific gas concentration inside the oven, the concentration can be converted into a voltage value form, and the voltage value is collected by the comparator in the concentration comparison circuit and compared with the voltage thresholds corresponding to the first concentration threshold and the second concentration threshold, respectively, so as to achieve the comparison of the specific gas concentration in the form of voltage comparison. When the specific gas concentration is greater than the first concentration threshold, the voltage value exceeds the voltage threshold corresponding to the first concentration threshold, and the output signal of the comparator can trigger the signal sending circuit to generate and send the convection adjustment signal until the voltage value is less than the voltage threshold corresponding to the second concentration threshold, and the triggering of the signal sending circuit is stopped.

[0088] It should be noted that since the objects to which the signal sending circuit sends signals in each judgment situation are different, the contents of the generated opening signal, closing signal, temperature control signal, ventilation adjustment signal and convection adjustment signal may be the same or different, and the signals may be implemented in the form of digital signals or PLC instructions. The utility model does not limit the signal content.

[0089] Optionally, it further comprises a circuit breaker component electrically connected to the control module 1;

[0090] The circuit breaker component is used to cut off the power of the infrared heating control system when receiving a power-off signal sent by the control module 1.

[0091] In this embodiment, in order to further ensure the safety of the oven during operation, the infrared heating control system can also be provided with a circuit breaker component electrically connected to the control module 1. When the control module 1 triggers all explosion-proof execution ends to cool down the infrared heating device 2 and none of them can achieve the cooling purpose, it is determined that the explosion-proof execution end may not be able to operate or an unhandled accident may occur. A power-off signal can be directly sent to the circuit breaker component to cut off the power to the infrared heating control system. At the same time, an alarm can be connected to provide sound, image or information alarm to inform technical personnel to verify and handle the situation.

[0092] The embodiment of the utility model provides an infrared heating control system, comprising a control module, multiple explosion-proof actuators, at least one group of first detection components and at least one group of second detection components; the first detection component is installed inside the infrared heating device, and is used to detect the internal temperature of the infrared heating device and send it to the control module; the second detection component is installed outside the infrared heating device, and is used to detect the external temperature of the infrared heating device and send it to the control module; the control module is electrically connected to each explosion-proof actuator, and is used to regulate at least one explosion-proof actuator according to the internal temperature and / or the external temperature, and the explosion-proof actuator performs a rapid ventilation action when the internal temperature or the external temperature rises abnormally, thereby realizing temperature control of the infrared heating device, so as to effectively improve the safety of use of the infrared heating device.
