Description

Technical Field

[0001] This invention relates to the field of solar module manufacturing technology, and in particular to a heat dissipation and static electricity elimination device for the discharge area of ​​a laminator. Background Technology

[0002] Solar photovoltaic (PV) modules are the core and most important component of a solar power generation system. A typical PV module consists of layers of tempered glass, EVA (ethylene glycol), solar cells, fiberglass, and a backsheet, stacked sequentially from bottom to top. Lamination is a crucial step in PV module production. The laminated PV modules are placed in a laminator, where air is removed through a vacuum system, and then the EVA is heated to melt and bond the cells, glass, and backsheet together. After lamination, the PV modules must be cooled by a discharge cooling system before being transported to the next stage of production. Currently, a belt conveyor is used for this purpose, allowing the laminated PV modules to move and dissipate heat naturally.

[0003] Chinese invention patent CN110993730A discloses a heat dissipation device for a solar photovoltaic module laminator, comprising: a frame; several motor-driven conveying rollers are movably supported between the left and right side plates of the frame, arranged sequentially from front to back along the conveying direction of the solar photovoltaic modules, forming a conveying platform for receiving and conveying the solar photovoltaic modules; a photovoltaic module temporary storage mechanism is also provided in the frame to support the solar photovoltaic modules on the conveying platform; a rear door is provided on the frame behind the conveying platform to open or close the discharge end of the conveying platform; several air coolers are respectively provided on the rear door and on the frames on the left and right sides of the conveying platform to blow air and dissipate heat on the solar photovoltaic modules placed on the conveying platform and the photovoltaic module temporary storage mechanism; and an air collecting hood is provided on the frame above the conveying platform, with the air collecting hood connected to the air fans through an air duct. This invention has the advantage of good heat dissipation effect.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: existing heat dissipation devices typically only have a single heat dissipation function, and the heat dissipation efficiency is generally low; furthermore, they cannot remove static electricity generated during the lamination and transmission of solar panels. Therefore, a heat dissipation and static electricity elimination device for the discharge area of ​​a laminator is proposed. Summary of the Invention

[0005] The present invention proposes a heat dissipation and static electricity elimination device for the discharge area of ​​a laminator, which solves the problems that existing heat dissipation devices usually only have a single heat dissipation function, have general heat dissipation efficiency, and cannot remove static electricity adsorbed by solar panels.

[0006] A heat dissipation and static electricity elimination device for the discharging area of a laminator proposed by the present invention includes:

[0007] A support frame;

[0008] A transmission frame: A number of transmission frames are installed above the support frame to transmit the laminated solar panels;

[0009] A cooling component, which is installed above the support frame and wraps the transmission frame. A cold liquid circulates inside the cooling component to cool the laminated solar panels. Water droplets are formed when the air flow inside the inner wall of the cooling component meets the cold.

[0010] A blowing component, which is installed on the side wall of the cooling component. The blowing component blows air to cool the laminated solar panels and at the same time dries the water droplets. The evaporated dried water droplets increase the air humidity inside the inner wall of the cooling component.

[0011] By adopting the above technical solutions, the laminated solar panels are transmitted above the support frame. The cooling component cools itself by circulating cold liquid inside. While cooling, the ambient temperature inside the inner wall is reduced, realizing rapid cooling while sealing and transmitting the solar panels. The blowing component cooperates with the cooling component to further improve the cooling effect; water droplets are formed when the air flow inside the inner wall of the cooling component meets the cold and are dried by the blowing component. This process increases the air humidity inside the inner wall of the cooling component. The solar panels are transmitted in an environment with high humidity, greatly reducing the generation of static electricity.

[0012] Preferably, a conveyor belt is installed on the inner wall of the transmission frame, and the conveyor belt is a conductive conveyor belt.

[0013] Preferably, the cooling component includes a sealing frame, which is a "C"-shaped plate structure. The sealing frame is installed above the support frame and on the periphery of the transmission frame. A cold liquid cavity is opened inside the sealing frame, and a cold liquid circulates inside the cold liquid cavity. Preferably, the cold liquid is cold water. A liquid inlet pipe is connected to the upper surface of the sealing frame, and a bottom plate for guiding the blowing air flow of the blowing component is installed below the transmission frame.

[0014] Preferably, the bottom plate is provided with a cold conduction groove, and two groups of connecting pipes are connected between the cold liquid cavity and the cold conduction groove. When the blowing component blows the solar panels during transmission, the air flow is separated into an upper air flow and a lower air flow by the solar panels; the lower air flow is guided by the bottom plate to blow the bottom of the solar panels.

[0015] By adopting the above technical solution, the coolant flows into the cooling channel, effectively reducing the temperature of the transmission space at the bottom of the solar panel, allowing the bottom of the solar panel to be cooled evenly. The blower assembly blows air onto the solar panel, and when the solar panel reaches the inside of the sealed frame, the upper and lower airflows cool both sides of the solar panel evenly, greatly improving the cooling efficiency. When the solar panel reaches the outlet of the sealed frame, the blower assembly is blocked by the solar panel and only blows air onto the upper surface of the solar panel. At this time, the solar panel has been cooled, and the blower assembly plays the role of drying water droplets.

[0016] Preferably, the inner wall of the sealing frame is lined with cotton gauze, which absorbs water droplets formed when the airflow cools.

[0017] By adopting the above technical solution, the cotton gauze can effectively absorb water droplets, preventing water droplets from falling onto the solar panel, while ensuring good breathability, allowing the blower component to stably blow on the cotton gauze, thus drying the cotton gauze and increasing humidity.

[0018] Preferably, the blower assembly includes a fixed frame, a mounting plate, and a cooling fan. The fixed frame is fixedly installed on the side wall of the sealing frame, and the mounting plate is rotatably installed on the inner wall of the fixed frame. The mounting plate has several mounting slots inside, and the cooling fan is installed inside the mounting slots. A fastening knob is installed on one side wall of the fixed frame.

[0019] By adopting the above technical solution, the cooling fan is used for airflow cooling; by adjusting the fastening knob, the airflow angle of the mounting plate and the cooling fan can be adjusted.

[0020] Preferably, a support platform is fixedly installed on the inner wall of the support frame, and a bracket is fixedly connected to each support platform relative to the inner side wall, with the base plate installed on the upper surface of the bracket.

[0021] Preferably, the bottom surface of the cooling channel is connected to a discharge pipe, and a valve is installed on the periphery of the discharge pipe.

[0022] Preferably, a metal rod is connected to the inner wall of the transmission frame and the support platform, one end of the metal rod is in contact with the conductive conveyor belt, and a grounding wire is connected to the bottom surface of the support platform.

[0023] By adopting the above technical solution, and by having the metal rod contact the conveyor belt in conjunction with the grounding wire, static electricity generated during the lamination and transmission of solar panels can be quickly removed.

[0024] The beneficial effects of this invention are:

[0025] By circulating coolant inside the cooling component, the ambient temperature of the inner wall of the cooling component is lowered, achieving rapid cooling while sealing and transmitting the solar panel. The blower component works in conjunction with the cooling component to further enhance the cooling effect. When the airflow inside the cooling component encounters the cold air, it forms water droplets, which are then dried by the blower component. This process increases the air humidity inside the cooling component. The solar panel is transmitted in a high-humidity environment, which greatly reduces the generation of static electricity. Combined with the metal rod and grounding wire, static electricity generated by solar panel lamination and transmission is quickly eliminated. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Example 1: Refer to Figures 1-7A heat dissipation and static elimination device for the discharge area of ​​a laminator includes a support frame 1 and a transmission frame 2. Several transmission frames 2 are installed above the support frame 1 to transport the laminated solar panels. A conductive conveyor belt 3 is installed on the inner wall of each transmission frame 2. A metal rod 11 connects the transmission frame 2 to the inner wall of a support platform 101. A grounding wire 12 is connected to the bottom surface of the support platform 101. A sealing frame 4 is a U-shaped plate structure, installed above the support frame 1 and located around the transmission frames 2. The sealing frame 4 contains... The unit has a cold liquid chamber 5, which is filled with cold liquid, preferably cold water. The upper surface of the sealing frame 4 is connected to an inlet pipe 6. A support platform 101 is fixedly installed on the inner wall of the support frame 1. A support platform 17 is fixedly connected to the inner side wall of the support platform 101. A base plate 7 is installed on the upper surface of the support platform 17. A cooling channel 701 is provided on the base plate 7. Two sets of connecting pipes 8 are connected between the cold liquid chamber 5 and the cooling channel 701. A discharge pipe 9 is connected to the bottom surface of the cooling channel 701. A valve 10 is installed on the side of the discharge pipe 9.

[0036] The laminated solar panels are transported on conveyor belt 3 above support frame 1. During lamination and transport, the solar panels generate static electricity. Cold liquid is introduced into cold liquid chamber 5 through inlet pipe 6 and flows into cooling channel 701. After the cold liquid fills cold liquid chamber 5 and cooling channel 701, the ambient temperature around the sealing frame 4 drops rapidly. The circulation of cold liquid is achieved through external cold liquid, in conjunction with inlet pipe 6 and outlet pipe 9. The sealing frame 4 can seal the solar panels during transport, preventing external impurities from falling on the surface of the solar panels. At the same time, it rapidly cools the solar panels. Cooling fan 15 works to further enhance the cooling effect of the solar panels. The airflow on the inner wall of the sealing frame 4 forms water droplets when it encounters the cold air. After being dried by the airflow of cooling fan 15, the water droplets disperse to the inner wall of the sealing frame 4. This process increases the air humidity on the inner wall of the sealing frame 4. The solar panels are transported in a high-humidity environment, reducing the generation of static electricity. Metal rod 11 contacts conveyor belt 3 and, in conjunction with grounding wire 12, quickly conducts the static electricity generated during the lamination and transport of the solar panels to the ground, thus eliminating static electricity.

[0037] A fixing bracket 13 is fixedly installed on the side wall of the sealing frame 4. An installation plate 14 is rotatably installed on the inner wall of the fixing bracket 13. Several installation slots are opened inside the installation plate 14. Cooling fans 15 are installed inside the installation slots. A fastening knob 16 is installed on one side wall of the fixing bracket 13. Adjusting the fastening knob 16 can adjust the blowing angle of the installation plate 14 and the cooling fan 15.

[0038] The inner wall of the sealing frame 4 is lined with cotton gauze 18, which absorbs water droplets formed when the airflow cools. The cotton gauze 18 can effectively absorb water droplets, preventing them from falling onto the solar panel, while ensuring good air permeability, allowing the blower component to stably blow on the cotton gauze 18, and drying the cotton gauze 18 to achieve the effect of increasing humidity.

[0039] Working principle: The laminated solar panel is transported on conveyor belt 3; cold liquid is introduced into cold liquid chamber 5 through liquid inlet pipe 6, and the cold liquid flows into cold guide groove 701. After the cold liquid fills cold liquid chamber 5 and cold guide groove 701, the ambient temperature around the sealing frame 4 drops rapidly, and the solar panel is cooled down rapidly. Cooling fan 15 works to further improve the cooling effect of solar panel, increase the air humidity inside the sealing frame 4, and reduce the generation of static electricity; metal rod 11 contacts conveyor belt 3, and together with grounding wire 12, quickly conducts the static electricity generated during the lamination and transportation of solar panel to the ground, realizing the elimination of static electricity.
