The pressing plate 4 is arranged on the outside of the hot spot head 5, and the heating rod 6 is connected to the top of the hot spot head 5. The heating rod 6 is used to heat the hot spot head 5. The surface of the hot spot head 5 is provided with a Teflon coating. The Teflon coating has strong wear resistance and can effectively resist various wear and erosion. The Teflon coating has excellent corrosion resistance to most chemical substances. The Teflon coating can be used at a temperature of up to 260°C and can still maintain stable physical and chemical properties at high temperatures, thereby extending the service life of the hot spot head 5. The Teflon coating has strong non-stickiness and almost no substance can adhere to it. This is mainly due to its extremely low surface tension. This characteristic makes it difficult for the hot spot head 5 to adhere to the EVA strip 3 during the hot spot process and makes the hot spot head 5 easy to clean and maintain.

[0038] In this embodiment, it also includes glass 1, bottom layer EVA 2 and EVA strips 3.

A through hole is provided at the top of the pressure plate 4, and the front side of the through hole is opened. The hot head 5 is provided directly above the through hole, and the hot head 5 can pass through the through hole so that the pressure plate 4 can block the hot head 5.

[0042] In this embodiment, a mounting cylinder 801 is fixedly connected to the top of the moving platform 702, and both ends of the mounting cylinder 801 are rotatably connected to support wheels 8, and the support wheels 8 are used to support the glass 1. Both ends of the mounting cylinder 801 are provided with speed sensors 802, and the support wheels 8 are connected to the corresponding speed sensors 802, and the speed sensors 802 are used to monitor the speed of the support wheels 8; both ends of the mounting cylinder 801 are fixedly connected to a first adjustable rotation damper 803, and the movable end of the first adjustable rotation damper 803 is fixedly connected to the support wheel 8, and the first adjustable rotation damper 803 is used to provide rotation resistance for the support wheel 8, and the resistance is adjustable, the speed sensor 802 is connected to the first adjustable rotation damper 803 signal, and the first adjustable rotation damper 803 controls the increase of damping according to the increase of the speed monitored by the speed sensor 802; the top of the moving platform 702 is fixedly connected to a mounting cylinder 801, and the mounting cylinder 801 is provided with a rotation sensor 802, and the support wheel 8 is connected to the corresponding speed sensor 802, and the speed sensor 802 is used to monitor the speed of the support wheel 8; A column 19 is provided, and the top end of the mounting column 19 is rotatably connected to an abutment wheel 14, and the abutment wheel 14 is used to abut against the edge of the glass 1 to achieve positioning. A pressure sensor 18 is fixedly connected to the top end of the mounting column 19, and the pressure sensor 18 is used to monitor the pressure exerted on the abutment wheel 14. A second adjustable rotary damper 17 is fixedly connected to the outer side of the mounting column 19, and the movable end of the second adjustable rotary damper 17 is connected to the abutment wheel 14. The pressure sensor 18 is connected to the first adjustable rotary damper 803 and the second adjustable rotary damper 17. When the pressure sensor 18 detects that the pressure reaches a preset value, the first adjustable rotary damper 803 and the second adjustable rotary damper 17 are controlled to increase to the maximum value to achieve positioning of the glass 1. The models of the first adjustable rotary damper 803 and the second adjustable rotary damper 17 are both HY13A0, so as to achieve precise control of the rotation speed and torque.

[0043] In this embodiment, the module 7 adopts a linear module 7, whose model is Compact Linear Systems. The linear module has the characteristics of high-precision positioning, high-speed movement, high-rigidity structure, high load capacity, compactness and lightness, so as to achieve accurate and efficient linear motion control. A base 15 is fixedly installed at the bottom of the module 7.

[0044] In this embodiment, the mounting beam 9 is made of aluminum alloy. Since the density of aluminum alloy is one-third of that of steel, and the tensile strength of aluminum alloy can be significantly improved after heat treatment and alloying strengthening, which is sufficient to meet the needs of most structural materials. Due to its light weight, the use of the mounting beam 9 can significantly reduce the weight of the entire structure, thereby reducing the load of the building, reducing energy consumption and costs. Aluminum alloy will naturally form a dense aluminum oxide film in the air, which can effectively protect the internal metal from corrosion and maintain stability for a long time even in harsh environments. The support wheel 8 and the abutment wheel 14 are both made of rubber, so that they can play an anti-seismic and anti-slip effect when in contact with the glass 1. Rubber has high elasticity, which enables the support wheel 8 to effectively absorb vibration during the load and rolling process. This characteristic is particularly critical for preventing the glass 1 from being impacted and vibrated during movement. The static friction between the rubber and the glass 1 is large, which makes the support wheel 8 not easy to slide when subjected to gravity, ensuring the stability of the glass 1 during placement and movement. In addition, the rubber has excellent anti-oxidation and anti-ozone properties, and can resist long-term sunlight exposure and climate change, maintaining stable performance.

[0045] In this embodiment, when in use, the control module 7 is used to start the horizontal movement of the moving platform 702, and then the glass 1 and the bottom EVA 2 are placed on the top of the supporting wheel 8 and pushed horizontally. During the pushing process, the glass 1 drives the supporting wheel 8 to rotate by contacting with the supporting wheel 8. The speed sensor 802 monitors the rotation speed of the supporting wheel 8, thereby monitoring the pushing speed of the glass 1, and the first adjustable rotation damper 803 controls the damping to increase according to the increase in the speed monitored by the speed sensor 802, thereby ensuring the smooth pushing of the glass 1 and avoiding collision damage caused by excessive pushing speed;

[0046] By pushing the glass 1 until its edge abuts against the abutment wheel 14, then fine-tuning the position of the glass 1 horizontally, and then continuing to push the glass 1, the glass 1 is closely abutted against the abutment wheel 14. When the pressure sensor 18 detects that the pressure reaches a preset value, the first adjustable rotary damper 803 and the second adjustable rotary damper 17 are controlled to rise to the maximum value to achieve the positioning of the glass 1.

[0047] The EVA strip 3 is laid on the bottom layer EVA2 and the electric push rod 16 is started to drive the connecting seat 701 to move downward, thereby driving the mounting beam 9 to move downward, and the mounting seat 10 drives multiple mounting seats 10 to move downward. The mounting seat 10 drives the pressure plate 4 to move downward through the compression spring 403, so that the pressure plate 4 abuts on the EVA strip 3, thereby achieving the effect of pressing the EVA strip 3 and the bottom layer EVA2 tightly, and then the electric push rod 16 is continued to be controlled to drive the mounting seat 10 to descend and compress the compression spring 403, the mounting seat 10 drives the spot ironing head 5 to move downward and abut against the joint between the EVA strip 3 and the bottom layer EVA2, and then the heating rod 6 is started to heat the spot ironing head 5, so that the EVA strip 3 and the bottom layer EVA2 can be ironed together, realizing multi-point automatic positioning and spot ironing;

[0048] After the hot pressing is completed, the electric push rod 16 is started to drive the mounting beam 9 and the mounting seat 10 to move downward, thereby first driving the hot pressing head 5 to move upward. At this time, the compression spring 403 is in a compressed state, so that the pressure plate 4 can maintain the compression effect of the EVA strip 3. Therefore, the hot pressing head 5 will not lift the EVA strip 3 when it moves upward, avoiding adhesion and causing secondary damage to the battery string assembly, thereby ensuring the adhesion firmness of the EVA strip 3 and the bottom EVA2.

Specific embodiments are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea.
