Different temperature zones have different effects on battery cells. It is difficult for existing sintering furnaces to effectively control the temperature of each temperature zone, especially to avoid excessively high or low temperatures from affecting the coated silver paste or other metal materials. At the same time, the temperature series phenomenon will have a great impact on the temperature between each sintering temperature zone, resulting in frequent fluctuations in the sintering PID curve, which is easy to cause uneven corrosion of the wire mesh silver paste on the battery cell, and then make the ohmic contact of the battery cell poor, which may lead to low battery conversion efficiency.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 11 The present invention provides a technical solution: a temperature control method for a wire mesh sintering furnace, comprising the following steps: S1. Temperature monitoring: sensor modules for monitoring the temperature of the corresponding functional areas are set in the preheating area, sintering area and cooling area of ​​the furnace body 1 to collect temperature data in real time and transmit the temperature data to the control module. The number of temperature sensors in the sensor module is increased in time according to the needs of the functional area to ensure the comprehensiveness of temperature monitoring in each section; S2. Temperature difference measurement: The control module will analyze the temperature of different functional areas in real time and compare it with the preset temperature value to determine the temperature deviation of each area; S3, dynamic temperature control: S31, power adjustment: in the sintering area, the control module dynamically adjusts the lamp power according to the difference between the real-time temperature and the set temperature, and further adjusts the operation state of the high-heat lamp 12 of the low-heat lamp 11 according to the difference between the real-time temperature and the set temperature; S32, series temperature adjustment: when the control module detects that the temperature of the preheating zone or the cooling zone exceeds the set temperature, and the temperature of the sintering zone is within the set temperature range, the horizontal position of the lamp tube is adjusted to make the position of the lamp tube in the sintering zone away from the functional zone exceeding the set temperature; S4. Data recording: The operator can view the real-time temperature data through the human-machine interface and adjust the temperature setting of each functional area. The human-machine interface is used to display the temperature deviation, power adjustment and equipment operation status to ensure that the operator can understand the operation status of the sintering furnace in time; S5. Maintenance and optimization: Regularly check the performance of the sensor module and lamp to ensure that they are in good working condition. If the temperature control effect of any functional area is not ideal, promptly check and replace the temperature sensor or adjust the control strategy. According to different seasons or environmental changes, appropriately optimize and adjust the temperature setting of the sintering furnace to cope with the impact of external temperature fluctuations.

[0020] like Figure 1 As shown, target temperatures are set in various functional zones (such as preheating zone, sintering zone, cooling zone, etc.) in the furnace body 1, and the real-time temperature of each functional zone is fed back through the sensor module, wherein a plurality of groups of temperature sensors arranged in each functional zone transmit the monitored temperature signals to the control module in real time, and the control module calculates the average value of the plurality of temperature signals, and the calculated average temperature value is the temperature value of the functional zone.

[0021] The temperature difference of each functional zone is obtained by comparing the set value of each functional zone with the average temperature value of the functional zone. Taking the sintering zone as an example, the calculation formula is: ,in Expressed as the temperature difference in the sintering zone, It is expressed as the actual average temperature of the sintering zone. Indicates the set temperature value of the sintering zone.

[0022] pass The value is used to obtain the number of lamps that need to be adjusted in the sintering area, where the calculation formula is: , Expressed as the maximum number of high heat lamps 12, It is expressed as the number of high-heat lamps 12 that need to be turned off. It is expressed as the maximum temperature difference that can be tolerated in the sintering zone. It is expressed as an integer rounded up, which means that at least one high-heat lamp 12 is guaranteed to be turned off.

[0023] It should be noted that after the high-heat lamp 12 is turned off, the corresponding low-heat lamp 11 is turned on, so the number of low-heat lamps 11 in operation is consistent with the number of high-heat lamps 12 that are turned off. The values ​​are consistent, so when When it is greater than 0, some high-heat lamps 12 are turned off, and a corresponding number of low-heat lamps 11 are turned on. When it is less than or equal to 0, the operating state of the high-heat lamp tube 12 is restored according to actual needs.

[0024] At the same time, the temperature difference values ​​of the three functional zones are compared. When only the temperature in the sintering zone is too high, the operating states of multiple groups of low-heat lamps 11 and high-heat lamps 12 are adjusted to achieve the purpose of cooling the sintering zone. At the same time, when the temperatures of the sintering zone and the preheating zone are high and the temperature of the cooling zone is within the set range, the horizontal position of the lamp in the sintering zone is changed to make it closer to the cooling zone, thereby reducing the temperature connection phenomenon from the sintering zone to the preheating zone. According to the temperature difference between the actual temperature of the sintering zone and the preheating zone and the set temperature, the operating states of the low-heat lamps 11 and the high-heat lamps 12 are synchronously adjusted.

[0025] And when the temperature of the sintering zone and the cooling zone is high, and the temperature of the preheating zone is within the set range, on the contrary, the different temperature changes of the three groups of functional zones are used to reduce the influence of the temperature conditions in the sintering zone on the temperature of the adjacent functional zones, thereby ensuring that the three groups of functional zones in the furnace body 1 can be within the normal working temperature.

[0026] The control module will record the temperature change data of each functional area in real time and generate a temperature curve for the operator to analyze. It can also set regular temperature calibration to ensure the accuracy of temperature control. At the same time, according to the temperature change trend during the sintering process, the temperature control strategy of the sintering furnace is adjusted for feedback. Through real-time temperature control and adjustment of each temperature zone, it can effectively avoid damage to the battery cells or other materials caused by excessively high or low temperatures during the sintering process, thereby improving the stability and efficiency of the sintering process and ensuring the quality of the final product.

[0027] One of the more preferred embodiments is a temperature control method for a wire mesh sintering furnace, comprising a furnace body 1 and lamps for increasing the temperature of a functional area, wherein the lamps in the sintering area include a plurality of groups of low-heat lamps 11 and high-heat lamps 12, and the furnace body 1 is provided with a temperature control structure for adjusting the operating state of the lamps in the sintering area; The temperature control structure includes a plurality of U-shaped support frames 10 arranged on the furnace body 1, the plurality of U-shaped support frames 10 are arranged in a linear array on the furnace body 1, the low-heat lamp tubes 11 and the high-heat lamp tubes 12 are both arranged on the U-shaped support frames 10, and the U-shaped support frames 10 are provided with a closed-loop component for driving the low-heat lamp tubes 11 and the high-heat lamp tubes 12 to start and stop; The furnace body 1 is provided with a blocking slide groove 24 for the U-shaped support frame 10 to slide and connect in the horizontal direction, and the furnace body 1 is provided with a translation component for driving multiple groups of U-shaped support frames 10 to move synchronously horizontally in the sintering area.

[0028] like Figure 2 and Figure 3 As shown, a plurality of groups of U-shaped support frames 10 are arranged in the sintering zone, and the plurality of groups of U-shaped support frames 10 are horizontally slidably arranged on the furnace body 1. The plurality of groups of U-shaped support frames 10 can be driven to move horizontally synchronously through the translation assembly, so as to move away from or close to the adjacent functional zone, thereby reducing the temperature impact on the functional zone with abnormal temperature, so as to avoid the temperature of the adjacent functional zone continuing to rise abnormally due to the temperature transmission phenomenon.

[0029] At the same time, when the temperature of the sintering zone is too high, part of the low-heat lamps 11 can be turned off through the closed-loop component, and a corresponding number of high-heat lamps 12 can be driven to operate, thereby reducing the total heating power of the sintering zone to avoid the temperature of the sintering zone from continuing to rise, and driving the temperature of the sintering zone to return to the set temperature by reducing the total heating power, thereby avoiding excessively high or low temperatures from causing adverse effects on the silver paste or other metal materials coated on the battery cells.

[0030] Furthermore, the translation assembly includes a leveling plate 2 arranged on the furnace body 1, a side plate 3 is fixedly connected below the leveling plate 2, a group of limit pins 15 are fixedly connected at both ends of the U-shaped support frame 10, and a limit groove 16 is opened on the leveling plate 2 for the limit pin 15 to be slidably connected.

[0031] The furnace body 1 is fixedly connected with a positioning seat 4, on which a transverse seat 5 is provided which is driven by an electric push rod and can move freely in the horizontal direction. The positioning seat 4 is provided with a rectangular groove for the transverse seat 5 to slide horizontally, and the transverse seat 5 is provided with a downward extension rod 6 which moves horizontally synchronously with the transverse seat 5, and the transverse seat 5 is fixedly connected with the leveling plate 2.

[0032] like Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, the transverse seat 5 is driven by an electric push rod to slide horizontally on the positioning seat 4, thereby driving the downward extension rod 6 which moves horizontally synchronously with the positioning seat 4, wherein the downward extension rod 6 is fixedly connected between the horizontal plate 2 and the side plate 3, and the limit pin 15 arranged at the end of the U-shaped support frame 10 is slidably connected to the side plate 3 through the limit groove 16. When the horizontal position of the side plate 3 changes, multiple groups of U-shaped support frames 10 can be driven to move synchronously in the horizontal direction.

[0033] Among them, by changing the horizontal position of multiple groups of U-shaped support frames 10 to make them away from or close to the preheating zone or the cooling zone, the impact on the abnormally rising functional zone can be reduced to avoid the continuous increase in temperature in the functional zone with abnormal temperature, thereby reducing the temperature loss caused by the temperature string phenomenon.

[0034] Based on the translation assembly embodiment, the closed-loop assembly includes a transverse shaft 13 that rotates freely in the vertical direction, the transverse shaft 13 rotates on the U-shaped support frame 10, two groups of bone plates 14 are fixedly connected to the transverse shaft 13, and the low-heat lamp tube 11 and the high-heat lamp tube 12 are symmetrically fixedly connected to the two groups of bone plates 14; The low-heat lamp tube 11 is electrically connected in series with a left-hand contact copper sheet 22, and the high-heat lamp tube 12 is electrically connected in series with a right-hand contact copper sheet 23. The U-shaped support frame 10 is provided with a co-located contact copper sheet 20 electrically connected to the left-hand contact copper sheet 22 and the right-hand contact copper sheet 23. The low-heat lamp tube 11 and the high-heat lamp tube 12 are arranged in parallel.

[0035] An arc-shaped inner frame 19 is fixedly connected to the U-shaped support frame 10, and a co-positioned contact copper sheet 20 is fixedly connected to the inner wall of the arc-shaped inner frame 19. A convex swing rod 21 is coaxially fixed to the transverse axis 13. The convex swing rod 21 is provided with a receiving groove for receiving a left-direction contact copper sheet 22 and a right-direction contact copper sheet 23, and the left-direction contact copper sheet 22 and the right-direction contact copper sheet 23 are both fixedly connected to the convex swing rod 21.

[0036] The transverse shaft 13 slides through the limiting pin 15 and is coaxially fixed with a gear 17 . The gear 17 is meshedly connected with an oblique rack 18 . The oblique rack 18 and the limiting groove 16 are arranged in parallel.

[0037] like Figure 2 , Figure 4 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11As shown, when the horizontal height of the side plate 3 changes, the horizontal position of the limit pin 15 can be slightly changed through the limit groove 16 opened thereon, wherein the limit pin 15 is fixedly set on the U-shaped support frame 10, so that the limit pin 15 and the side plate 3 can be driven to move relative to each other, and the movement direction is the opening direction of the limit groove 16.

[0038] At the same time, the oblique rack 18 is fixed on the side plate 3 and is arranged parallel to the limit groove 16. Therefore, when the limit pin 15 drives the gear 17 and the side plate 3 to move relative to each other through the transverse shaft 13, the gear 17 is engaged with the oblique rack 18, so that the gear 17 can drive the transverse shaft 13 to rotate in the vertical direction.

[0039] Among them, two groups of bone plates 14 are fixedly set on the transverse axis 13, and the low-heat lamp tube 11 and the high-heat lamp tube 12 are set on the bone plate 14, so that the relative positions of the low-heat lamp tube 11 and the high-heat lamp tube 12 can be changed, so that the lamp tube in operation is directed to the side of the processed part, and the low-heat lamp tube 11 is electrically connected to the left-hand contact copper sheet 22, and the high-heat lamp tube 12 is electrically connected to the right-hand contact copper sheet 23. When the transverse axis 13 rotates, it can drive the bone plate 14 to rotate to change the directions of the low-heat lamp tube 11 and the high-heat lamp tube 12, and can simultaneously drive the convex swing rod 21 fixed thereon to rotate.

[0040] At the same time, the left-hand contact copper sheet 22 and the right-hand contact copper sheet 23 are fixedly arranged on the convex rocker arm 21. When the convex rocker arm 21 rotates, the positions of the left-hand contact copper sheet 22 and the right-hand contact copper sheet 23 can be changed. When the U-shaped support frame 10 drives the convex rocker arm 21 to the final rotation position, the left-hand contact copper sheet 22 and the right-hand contact copper sheet 23 can be driven to have only one group to collide with the co-position contact copper sheet 20. Among them, the low-heat lamp tube 11 and the high-heat lamp tube 12 are arranged in parallel, and a smooth circuit is formed between the co-position contact copper sheet 20 and the external power supply equipment. Therefore, through the rotation process of the transverse shaft 13, the lamp tube facing the side of the part to be processed can be in operation.

[0041] On the basis of the closed-loop assembly embodiment, the lateral displacement seat 5 is provided with a vertical slide groove for the downward extension rod 6 to slide and connect in the vertical direction, and the downward extension rod 6 is provided with an end seat 7 for fixed axis rotation at one end away from the leveling plate 2; The furnace body 1 is provided with a swing seat 9 which is driven by a motor to rotate on a fixed axis and can rotate freely in a vertical direction. A guide pin 8 is fixedly connected to the outer peripheral surface of the swing seat 9, and an end seat 7 is slidably sleeved on the guide pin 8.

[0042] like Figure 2As shown, when the guide pin 8 is parallel to the positioning seat 4 and is in a horizontal state, the horizontal height of the lower extension rod 6 will not change when following the horizontal movement of the transverse seat 5. After the horizontal position adjustment of the transverse seat 5, the lower extension rod 6 and the side vertical plate 3 is completed, the swing seat 9 is driven by a motor to swing in the vertical direction, and then the lower extension rod 6 is driven to slide in the vertical direction at the transverse seat 5 by changing the height of the end seat 7, thereby changing the horizontal height of the side vertical plate 3, thereby achieving the purpose of changing the operating status of the low-heat lamp tube 11 and the high-heat lamp tube 12.

[0043] It should be noted that, since the horizontal movement process of the transverse moving seat 5 changes the horizontal position of the side plate 3, thereby making the lamp tube close to or away from the preheating zone and the cooling zone, the transverse moving seat 5 can change the horizontal position of the end seat 7 through the downward extension rod 6 when moving horizontally, thereby changing the distance between the end seat 7 and the swing seat 9, wherein the position of the swing seat 9 is the rotation center point of the guide pin 8, and when the swing seat 9 rotates a quantitative angle, the different horizontal positions of the end seat 7 will drive the downward extension rod 6 and the side plate 3 to move at different distances in the vertical direction. Therefore, in actual use, it is necessary to adaptively adjust the deflection angle of the swing seat 9 in the vertical direction according to the different horizontal positions of the transverse moving seat 5 and the side plate 3 to ensure that the lifting process of the side plate 3 can adjust the position of the low-heat lamp 11 and the low-heat lamp 11.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
