Description

TECHNICAL FIELD

[0001] The utility model relates to photovoltaic module laminating, encapsulating technical field, more specifically relates to a resistance type heating assembly laminating structure. BACKGROUND

[0002] In the production process of photovoltaic modules, laminating process is one of the key links. In the traditional laminating process, hot oil furnace is usually used to heat heat conducting oil, and then heat conducting oil is circulated to provide heat for the laminating machine to meet the demand of photovoltaic modules for stable temperature environment in the melting and crosslinking process. However, this traditional heating method has many problems.

[0003] Firstly, the heat conducting oil pipeline is an internal intercommunication structure, and the temperature uniformity of the whole platform is limited by the circulation speed of heat conducting oil. Due to the flow characteristics of heat conducting oil, there is a certain delay and unevenness in heat transfer, which may cause temperature difference in different areas of the platform, affecting the laminating quality.

[0004] Secondly, there are few temperature detection points in the traditional process, generally 5-24 detection intervals. This limited detection range cannot timely and effectively feedback the real temperature of the platform, making it difficult to accurately control and adjust the temperature, further aggravating the problem of temperature uniformity.

[0005] In addition, the traditional process lacks independent heat preservation edge area outside the effective laminating area. This makes it easy for heat to dissipate from the edge of the platform during the laminating process, resulting in a decrease in the temperature of the edge area and further affecting the stability and uniformity of the overall temperature.

[0006] The existence of these problems not only affects the laminating quality of photovoltaic modules, reduces the production efficiency, but also increases the maintenance cost and energy consumption of the equipment. Therefore, a new heating structure is needed to effectively solve the above problems and improve the stability and efficiency of the laminating process. UTILITY MODEL CONTENT

[0007] Therefore, the utility model provides a resistance type heating assembly laminating structure, aiming at solving the above technical problems.

[0008] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0009] A resistance type heating assembly laminating structure, comprising:

[0010] A mounting substrate;

[0011] A plurality of resistance heating unit plates are arranged in a matrix on the surface of the mounting substrate, and each resistance heating unit plate is detachably connected to the mounting substrate.

[0012] By the above technical solution, the plurality of resistance heating unit plates are arranged in a matrix on the surface of the mounting substrate, so that heat can be more evenly distributed, and the temperature difference problem of different areas of the platform caused by heat transfer delay and unevenness in the traditional heating mode is avoided, thereby improving the laminating quality. Each resistance heating unit plate is detachably connected to the mounting substrate, and this structure design allows the individual replacement and maintenance of a faulty heating unit without replacing the entire heating assembly, thereby reducing maintenance cost and time. Each resistance heating unit plate is provided with a temperature sensor, which can monitor the temperature of each heating unit in real time, realize accurate control and adjustment of the temperature, solve the problem of fewer temperature detection points and the inability to effectively feedback the real temperature of the platform in the traditional process, and further improve the accuracy and stability of temperature control.

[0013] Preferably, in the above-mentioned resistance heating assembly laminated structure, bolt holes are formed in the resistance heating unit plate, and the resistance heating unit plate is fastened and connected to the mounting substrate by bolts. The bolt fastening connection mode makes the connection between the resistance heating unit plate and the mounting substrate more firm and reliable, can withstand certain mechanical stress and thermal stress, ensures the stability of the heating assembly during long-term use, and avoids problems such as poor contact or abnormal heating caused by loose connection. The bolt connection mode is simple and convenient to operate, and is easy to realize the installation and disassembly of the resistance heating unit plate, thereby further improving the maintenance and replacement efficiency and reducing the maintenance cost.

[0014] Preferably, in the above-mentioned resistance heating assembly laminated structure, the resistance heating unit plate is a rectangular plate. The design of the rectangular plate allows the resistance heating unit plate to be better arranged in a matrix on the mounting substrate, and the layout is more regular, which is conducive to improving the space utilization rate and also helps to realize uniform distribution of heat and uniform control of temperature. The shape of the rectangular plate is relatively simple, which is convenient for processing and manufacturing, can reduce production cost, and improve production efficiency.

[0015] Preferably, in the above-mentioned resistive heating assembly laminated structure, the two long edges of the matrix heating unit composed of a plurality of the resistive heating unit plates are detachably connected with a plurality of first resistive heating edge plates, and the two short edges are detachably connected with a plurality of second resistive heating edge plates. By arranging the first resistive heating edge plates and the second resistive heating edge plates on the edges of the matrix heating unit, the edge area can be independently heated and insulated, effectively reducing the heat loss from the platform edge, further improving the stability and uniformity of the overall temperature, and solving the problem of temperature drop in the edge area in the traditional process, thereby improving the laminating quality. The edge plates are detachably connected with the mounting base plate, and the number and position of the edge plates can be flexibly adjusted according to different process requirements and specifications of the laminating assembly to achieve the best insulation effect and temperature control.

[0016] Preferably, in the above-mentioned resistive heating assembly laminated structure, the surface area of the first resistive heating edge plate and the second resistive heating edge plate is smaller than the surface area of the resistive heating unit plate. The surface area of the edge plate is smaller than the surface area of the resistive heating unit plate, so that the edge plate can more concentratedly generate heat when heated, improve the heating efficiency of the edge area, better compensate for the heat loss of the edge area, and further enhance the insulation effect. Smaller surface area means less material required for the edge plate, thereby reducing production costs, while also reducing the ineffective loss of heat and improving energy utilization efficiency.

[0017] Preferably, in the above-mentioned resistive heating assembly laminated structure, each of the first resistive heating edge plate and the second resistive heating edge plate is provided with a temperature measuring sensor. By installing a temperature measuring sensor on the edge plate, the temperature of the edge area can be monitored in real time, realizing comprehensive temperature monitoring of the entire heating assembly, ensuring that the temperature of the edge area can also be effectively controlled, and further improving the accuracy and stability of temperature control. Through the temperature measuring sensor on the edge plate, the temperature change of the edge area can be fed back in time, and when there is a temperature deviation, it can be quickly adjusted and compensated to avoid laminating quality problems caused by abnormal edge temperature.

[0018] Preferably, in the above-mentioned laminated structure of the resistance heating assembly, bolt holes are formed in the first and second resistance heating edge plates, and the first and second resistance heating edge plates are fastened to the mounting base plate by bolts. Similar to the resistance heating unit plate, the edge plate is fastened to the mounting base plate by bolts, so that the connection between the edge plate and the mounting base plate is more stable and reliable, can withstand certain mechanical stress and thermal stress, ensures the overall stability of the heating assembly, and avoids abnormal temperature control due to loose connection. The bolt connection mode facilitates the installation and disassembly of the edge plate, and when the edge plate fails or needs to be replaced, the operation can be quickly performed, further improving the maintenance efficiency and reducing the maintenance cost.

[0019] Preferably, in the above-mentioned laminated structure of the resistance heating assembly, the set temperature of the first and second resistance heating edge plates is higher than that of the resistance heating unit plate. Since the edge region is prone to heat loss, setting the temperature of the edge plate higher than that of the resistance heating unit plate can better compensate for the heat loss of the edge region, ensure that the temperature of the edge region is consistent with that of the internal region, and further improve the uniformity of the overall temperature. In this way, the problem of low temperature in the edge region can be effectively avoided, such as poor adhesion of the edge of the assembly, bubble generation, etc., thereby improving the laminating quality of the photovoltaic assembly and improving the qualification rate and reliability of the product.

[0020] According to the above technical solution, compared with the prior art, the laminated structure of the resistance heating assembly has the following advantages:

[0021] 1. Significantly improve temperature uniformity: The matrix-distributed resistance heating unit plates and the independent edge heating plates achieve uniform heat distribution, solving the problem of temperature non-uniformity caused by the flow characteristics of the heat conducting oil in the traditional heating method. The set temperature of the edge heating plate is higher than that of the main heating area, further compensating for the heat loss of the edge region and ensuring the consistency of the overall temperature.

[0022] 2. Accurate temperature control: Each heating unit plate and edge plate is equipped with a temperature sensor, realizing real-time temperature monitoring at multiple points and timely feedback of temperature changes, accurate temperature control and adjustment. The multi-point independent temperature control combined with the interlocking temperature compensation mechanism further improves the stability and reliability of temperature control.

[0023] 3. Reduce energy consumption and maintenance cost: The resistance heating does not require additional oil pump driving, reducing the energy consumption of the traditional oil heating system. Avoiding maintenance work such as replacement of heat conducting oil, pipeline cleaning and filtration maintenance, significantly reducing the maintenance cost and downtime of the equipment.

[0024] 4. Improved production efficiency and product quality: Through precise temperature control and uniform heating effect, the lamination quality problems caused by temperature fluctuations are reduced, and the qualification rate and reliability of photovoltaic modules are improved. Independent edge temperature control and interlocking compensation mechanism ensure the stability of the lamination process, and reduce the production interruption caused by temperature abnormalities.

[0025] 5. Flexible structure design: The heating unit plate and the edge plate are detachably connected, which is convenient for installation, maintenance and replacement, improves the service life and maintenance efficiency of the equipment. The rectangular plate design is convenient for processing and manufacturing, and can be flexibly adjusted according to different process requirements.

[0026] 6. Enhanced heat preservation performance: The design of the edge heating plate not only compensates for the heat loss of the edge area, but also forms an independent heat preservation edge area, reducing the invalid heat loss from the platform edge, and further improving the energy utilization efficiency.

[0027] 7. Strong adaptability: The structure is suitable for lamination processes of photovoltaic modules of various specifications, and has wide applicability and good expansibility.

[0028] 8. In line with environmental protection and energy saving trend: The resistance heating assembly does not need to use heat conducting oil, which reduces the potential impact on the environment and meets the environmental protection and energy saving requirements of modern industry.
