[0041] As shown in the figure, Figure 3 The pressurizing component 1 includes pressing plate 11, connecting block 12, cover plate 13 and pressing plate base 14, the pressing plate 11 and the cover plate 13 are connected as a whole through multiple connecting blocks 12, the cover plate 13 is connected with the pressing plate 11 by bolt, the pressing plate base 14 is installed on the side of cover plate 13 away from the pressing plate 11, and the pressing plate base 14 is connected with transmission component 2;The temperature control component 3 includes infrared microcrystalline heating plate 31 and temperature sensor 32, and each of the pressurizing component 1 of both sides is provided with a group of infrared microcrystalline heating plate 31 and temperature sensor 32;The infrared microcrystalline heating plate 31 is built-in in the pressing plate 11, and the temperature sensor 32 is provided with multiple, and multiple temperature sensors 32 are built-in in the pressing plate 11;

[0042] The module side plate glueing pressure maintaining function of the application is carried out according to the following steps:

[0043] The cylinder 21 in the transmission component 2 acts on the pressing plate base 14 of the one-side pressing component 1 through the connecting block 12; the pressing plate base 14 is pressed inwards along the slide rail 22 and the slide block 23 to drive the first connecting rod 24 to act, the rotary synchronization mechanism 26 is pulled to drive the second connecting rod 25 to act under the action of the first connecting rod 24, and the second connecting rod 25 drives the pressing plate base 14 in the other-side pressing component 1 to act through the connecting block 12; and the pressing plate base 14 in the other-side pressing component 1 is pressed inwards through the slide rail 22 and the slide block 23.

When the set holding time is reached, the infrared microcrystal heating plate 31 is turned off, the transmission component 2 is actuated to release the pressing component 1 to the original position, and the heating and curing are completed.

[0047] The temperature sensor 32 detects the temperature of the pressing plate 11, not the temperature of the module side plate gluing surface.

[0051]

[0052] In the formula, ε is the emissivity of the radiator, which can be obtained from a manual

[0053] σ is the Boltzmann constant, σ = 5.668 x 10 -8 w / (m 2 ·K 4 )

[0054] A1 - surface area of the radiator, m 2

[0055] T1 - surface temperature of the radiator, K

[0056] For the radiative heat exchange of the closed space surface in the pressing plate 11, the energy utilization rate η2 can be calculated by the following formula:

[0057]

[0058]

[0059] where ε n called the equivalent blackness

[0061] A2 - surface area of the heated object, m 2

[0062] T1 - surface temperature of the radiator, K

[0063] T2 - temperature of the heated object, K

[0064] W0 - electric power, Kw

[0065] As shown by the above formula, the heating efficiency of the infrared microcrystal heating plate 31 radiating the glue coating surface of the side plate of the heating module is related to the emissivity of the object surface, the object surface area, the object surface temperature, the electric power, and other factors. When the emissivity of the object surface, the object surface area, and the radiation conversion rate of the glue coating heating device of the side plate of the module are fixed values, the surface temperature of the radiator can be adjusted by controlling the electric power of the infrared microcrystal heating plate, and then the temperature of the heated pressing plate 11 can be controlled according to the energy utilization rate of the radiative heat exchange.

[0070] After pressurization, the infrared microcrystalline heating plate 31 in the pressure plate 11 is activated for heating. The temperature in the pressure plate 11 is fed back by the temperature sensor 32 and compared with the set temperature. If the set temperature is reached, the temperature control system adjusts the output power of the infrared microcrystalline heating plate 31 to maintain the temperature of the two pressure plates 11 at the set temperature. When the set heat preservation time is reached, the infrared microcrystalline heating plate 31 is turned off, and the transmission component 2 is controlled to release the pressure component 1 and return to the origin, thus completing the heating and curing process.

[0071] The heating process of the infrared microcrystalline heating plate 31 includes:

[0072] The infrared microcrystalline heating plate 31 converts electrical power into freely emitted radiant power;

[0073] The radiated power is absorbed by the heated pressure plate 11 and conducted to the adhesive surface of the module side plate.

[0074] The conversion efficiency η1 of the infrared microcrystalline heating plate 31 in converting electrical power into freely emitted radiant power is calculated using the following formula:

[0075]

[0076] In the formula, ε is the emissivity of the radiator, σ is the Schipfan-Boltzmann constant, A1 is the surface area of ​​the radiator, and T1 is the surface temperature of the radiator.

[0077] For the radiative heat exchange on the surface of the enclosed space in pressure plate 11, the energy utilization rate η2 is calculated using the following formula:
