Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic laminators, and in particular relates to a laminator with a cooling chamber and a stack. Background Art

[0002] In the field of laminating machine technology, the laminating machine includes a laminating machine, a feeding table and a discharging table. The feeding table transfers the laminated components to be pressed and packaged to the conveying part of the laminating machine, and the conveying part of the laminating machine transfers the laminated components to the predetermined position of the laminating workbench. The laminated components are pressurized and cured by the laminating machine to complete the packaging. The packaged photovoltaic components are transferred to the discharging table by the conveying part of the laminating machine. A cooling device is provided on the discharging table. After the components are cooled, they flow to the next process. With the innovation of photovoltaic industry technology, the production capacity of laminating machines is constantly improving, and the technical requirements for laminating machines are also constantly improving. At present, after the components are laminated in the laminating machine, the temperature of the components themselves reaches about 150 degrees, which is relatively high. The cooling device of the traditional discharging table is a fan set under the discharging table. When the photovoltaic components enter the discharging table, they are cooled while being transported, but the cooling speed of the cooling fan is slow, which reduces the overall production efficiency. In order to increase the cooling speed, a cooling laminating chamber is added if the site permits. However, when the site is limited, it is impossible to increase the cooling chamber. In order to solve this problem, a cooling stack discharge table is adopted, but the existing stack discharge table still uses a cold air blower as a cooling device. For example, the Chinese utility model patent No. 201920564624.4, entitled "Stacked Conveyor Table for Solar Cell Module Laminator", discloses a stacked conveyor table, which includes a table, a conveying device, a stacking device, and a lifting device for driving the stacking device up and down. It also includes a cooling device arranged on the table, and the cooling device includes a plurality of fans, and the air outlet of the fan faces the stacking device and / or the conveying working surface. With this structure, since a plurality of photovoltaic modules are stacked on the stacking device, each photovoltaic module is generating heat, and therefore, the heat cannot be taken away by air cooling, resulting in poor cooling effect. Utility Model Content

[0003] The utility model aims to provide a photovoltaic module laminator, a photovoltaic module cooling device and a cooling stack device used therein to address the shortcomings of poor cooling efficiency and low cooling efficiency of the prior art laminators.

[0004] The technical solution of the utility model to solve the technical problem is as follows:

[0005] A photovoltaic module cooling device comprises a photovoltaic module transmission mechanism and a photovoltaic module cooling mechanism, wherein the photovoltaic module transmission mechanism is a synchronous belt transmission mechanism, comprising a plurality of synchronous belts arranged in parallel, each synchronous belt being rotatably arranged on a frame body through a main transmission shaft and a driven shaft, the main transmission shaft being connected to the output end of the transmission drive, the photovoltaic module cooling mechanism comprising a plurality of cooling plates provided with cooling medium channels, a liquid inlet pipe and a liquid outlet pipe, and a cooling plate lifting mechanism, the liquid inlet pipe and the liquid outlet pipe being respectively connected to the inlet and the outlet of the cooling medium channel, the liquid inlet pipe and the liquid outlet pipe being used to connect the cooling plate with a cooling unit, the cooling medium in the cooling plate being circulated and cooled by the cooling unit, the cooling plates being respectively arranged between the gear spans of two adjacent synchronous belts, the output end of the cooling plate lifting mechanism being connected to the cooling plate, driving the cooling plate to rise so that the upper surface of the cooling plate is higher than the transmission plane of the synchronous belt so as to lift the photovoltaic module for cooling, or driving the cooling plate to descend so that the upper surface of the cooling plate is lower than the transmission plane of the synchronous belt so as to put the photovoltaic module back on the synchronous belt or to enable the synchronous belt to smoothly transmit the photovoltaic module;

[0006] The cooling plate lifting mechanism comprises a cooling plate support frame and a cylinder, the output end of the cylinder is fixedly connected to the cooling plate support frame, and each cooling plate is arranged on the cooling plate support frame.

[0007] A photovoltaic module cooling stack device, comprising a plurality of the above-mentioned photovoltaic module cooling devices, each photovoltaic module cooling device shares a frame, is arranged up and down, constitutes multiple layers of cooling plates arranged up and down and multiple layers of synchronous belts arranged up and down, and also comprises a stack frame and a photovoltaic module cooling device synchronous lifting device, the photovoltaic module cooling device synchronous lifting device comprises a lifting drive and a lifting transmission, the transmission component of the lifting transmission is fixedly connected to the frame, the lifting drive drives the lifting transmission to lift the frame so as to lift each photovoltaic module cooling device located on the frame, the photovoltaic module cooling device synchronous lifting device is arranged on the stack frame, and the cooling plate lifting mechanism is arranged on the frame;

[0008] The photovoltaic module cooling device synchronous lifting device comprises a driving motor and a chain transmission mechanism. The chain transmission mechanisms are respectively arranged on both sides of the stacking frame. The sprocket of the chain transmission mechanism is rotatably arranged on the stacking frame, and the chain is fixedly connected to the frame.

[0009] A photovoltaic module laminating machine comprises a laminating main machine. A discharging platform is arranged on the discharging side of the laminating main machine. The discharging platform adopts the photovoltaic module cooling device. The photovoltaic module conveying component of the laminating main machine is connected with a synchronous belt.

[0010] A photovoltaic module laminating machine comprises a laminating main machine, and a discharge platform is arranged on the discharge side of the laminating main machine. The discharge platform adopts the above-mentioned photovoltaic module cooling stack device. The photovoltaic module cooling device synchronous lifting device drives the frame to lift so that each layer of synchronous belts can dock with the photovoltaic module conveying component of the laminating main machine. Each layer of synchronous belts receives all the primary discharges of the laminating main machine, and the same discharge of the laminating main machine is cooled by the cooling plate.

[0011] The advantages and beneficial effects of the utility model are:

[0012] The photovoltaic module cooling device adopts the structure of the utility model, and the photovoltaic module can receive the heat transmitted from the upstream equipment through the synchronous belt, and the cooling plate lifting mechanism can drive the cooling plate to rise and fall. Therefore, when the synchronous belt receives the photovoltaic module, no interference will be generated between the cooling plate and the photovoltaic module. When the photovoltaic module needs to be cooled, the cooling plate can lift the photovoltaic module so that the photovoltaic module and the cooling plate are in direct surface contact. Therefore, the cooling effect is good. Since the cooling plate has a cooling channel, the cooling medium circulates through the liquid inlet pipe and the liquid return pipe. Therefore, the heat of the photovoltaic module can be taken away by the cooling medium in time, so that the ambient temperature in the overall area will not be significantly increased due to the heat dissipation of the photovoltaic module, thereby further improving the cooling effect of the photovoltaic module.

[0013] The photovoltaic module cooling stack device and photovoltaic module laminating machine adopt the structure of the utility model, multiple photovoltaic module cooling devices are arranged in the upper and lower layers, and the capacity of photovoltaic modules at the same work station is doubled. The photovoltaic module cooling devices at each layer are arranged on the frame, and are driven to rise and fall synchronously by the synchronous lifting device of the photovoltaic module cooling device. Therefore, they can rise and fall synchronously so that the synchronous belt of each layer can dock with the transmission component of the upstream equipment. Therefore, more photovoltaic modules can be received at the same time without changing the area occupied by the cooling device to match the increasing production capacity of the laminating host machine. Since a cooling plate with a cooling medium is used as a cooling component, the cooling medium circulates inside and outside the cooling plate. Therefore, the heat dissipation of the photovoltaic module can be taken away by the cooling medium in time, and will not gather at the cooling stack device, which will not cause adverse effects on the continuous cooling capacity of the cooling stack, so it can work continuously and stably.

[0020] The present invention is further described in detail below through specific embodiments. The following embodiments are only illustrative and not restrictive, and the protection scope of the present invention cannot be limited by them. Figure 1 The orientation shown illustrates the positions of the components.

[0021] like Figure 4As shown, the utility model provides a photovoltaic module cooling device, which includes a photovoltaic module transmission mechanism and a photovoltaic module cooling mechanism. The photovoltaic module transmission mechanism adopts a synchronous belt transmission mechanism, including a plurality of synchronous belts 14 arranged in parallel, each synchronous belt is arranged around the main transmission shaft 11 and the driven shaft 12 through a synchronous pulley 13 and is rotatably connected to the two, the top of each synchronous belt is in the same plane, the main transmission shaft and the driven shaft are both rotatably arranged on the frame 9, and the main transmission shaft is connected to the output end of the transmission drive 10. The photovoltaic module cooling mechanism of the utility model structure includes a cooling plate, a liquid inlet pipe and a liquid return pipe connecting the cooling plate to the cooling unit, and a cooling plate lifting mechanism for driving the cooling plate to rise and fall, the liquid inlet pipe includes a liquid inlet branch pipe and a liquid inlet main pipe, the liquid return pipe includes a liquid return branch pipe and a liquid return main pipe, a cooling plate 15 is arranged in the gear spacing of each two adjacent synchronous belts, each cooling plate 15 is arranged on a cooling plate support frame 16, and the upper surface of the plate body of the cooling plate is parallel to the top of the synchronous belt. The cooling plate lifting mechanism includes a cylinder and a cooling plate support frame. The output rod of the cylinder 17 is fixedly connected to the cooling plate support frame. The cylinder is fixedly arranged at the edge of the frame 9. The cooling plate support frame is driven by the cylinder to move up and down so that the upper surface of the cooling plate is lower than the top surface of the synchronous belt or higher than the top surface of the synchronous belt. A cooling medium channel is arranged in the cooling plate. The liquid inlet branch pipe 7 is connected to the inlet of the cooling channel, and the liquid return branch pipe 8 is connected to the outlet of the cooling channel. The cooling medium channel is connected to the liquid inlet main pipe 6 through the liquid inlet branch pipe, and is connected to the liquid return main pipe 5 through the liquid return branch pipe. The liquid return main pipe and the liquid inlet main pipe are used to communicate with the cooling unit 1. The cooling unit drives the cooling liquid to circulate, take away the heated cooling medium, and bring the low-temperature cooling medium into the cooling plate, and the cycle runs in this way. When receiving the component, the cylinder drives the cooling plate support frame to descend so that the upper surface of the cooling plate is lower than the top surface of the synchronous belt. The synchronous belt receives the component and transfers it to the position. When cooling is required, the cylinder drives the cooling plate support frame to rise so that the cooling plate is against the component for cooling, so that the cooling plate and the component are fully in contact, and the cooling efficiency is improved. After the cooling is completed, the cylinder drives the cooling plate support frame to descend below the top surface of the synchronous belt, and the component is supported by the synchronous belt again, and is driven by the synchronous belt to leave the cooling device and enter the next process. The photovoltaic component cooling device adopts this structure, the synchronous belt receives the component, the cylinder drives the cooling plate to descend so that the component is smoothly transferred to the position by the synchronous belt, and then the cylinder drives the cooling plate to rise and hold up the component and cool the component. In this process, the component and the cooling plate are in full contact, the contact is sufficient, the high-temperature medium is continuously replaced by the low-temperature medium, the heat is taken away, and sufficient heat exchange can be carried out with the component, so the cooling efficiency of the component is high. Make full use of the gear spacing between the synchronous belts, set the cooling plate within the gear spacing, and drive the cooling plate support frame to rise and fall by the cylinder, so that each cooling plate is in step with each other and the structure is simple. It can be used as a discharging platform to improve cooling efficiency. All synchronous belts of the photovoltaic module cooling device with this structure are located in the same transmission plane, and all cooling plates are located in the same lifting plane, commonly known as a single-layer photovoltaic module cooling device.

[0022] As the production capacity of photovoltaic module packaging equipment continues to increase, the number of photovoltaic modules laminated and packaged each time is increasing. Therefore, the number of modules that need to be cooled each time is also increasing. The production site, as a means of production, has limited resources. Especially in some areas where every inch of land is valuable, the above-mentioned photovoltaic module cooling device undoubtedly occupies a very large area. For this reason, the utility model also provides a photovoltaic module cooling stack device, which includes a multi-layer synchronous belt and a multi-layer cooling plate to solve the problem of insufficient space.

[0023] like Figure 1-3As shown, the basic structure of the photovoltaic module cooling stack device of the utility model adopts the basic structure of the photovoltaic module cooling device, which includes multiple groups of photovoltaic module conveying devices and multiple groups of photovoltaic module cooling mechanisms. On this basis, it also includes a photovoltaic module cooling device synchronous lifting device and a stack frame. The synchronous belt 14 of each group of photovoltaic module conveying devices is located in the same conveying plane, and the synchronous belts of multiple groups of photovoltaic module conveying devices are arranged in upper and lower layers. The cooling plates of each group of photovoltaic module cooling mechanisms are located between the gear spans of the synchronous belts of the same layer and are fixedly arranged on the cooling plate support frame of the same layer, that is, each group of cooling plates is equipped with a cooling plate support frame, and each cooling plate is located in the cooling plate support frame of the corresponding layer. The synchronous belts of each group of photovoltaic module conveying devices constitute a layer of synchronous belts, and the cooling plates in each group of photovoltaic module cooling devices constitute a layer of cooling plates. Each group of cooling mechanisms is equipped with a cooling plate lifting mechanism, and the output end of each group of cooling plate lifting mechanisms is fixedly connected to the corresponding cooling plate support frame. The cooling plate lifting mechanisms of each group are fixedly arranged on the frame 9. In order to smoothly lift the cooling plates, cooling plate lifting mechanisms are respectively arranged on both sides of the frame. The liquid inlet branch pipes of each group of cooling plates are connected to the liquid inlet main pipe, and the liquid return branch pipes are connected to the liquid return main pipe and thus connected to the cooling unit. This illustration shows 7 groups of photovoltaic module conveying devices, each of which includes 7 synchronous belts, and each cooling mechanism includes 6 cooling plates and two cylinders on the left and right. The photovoltaic module cooling device synchronous lifting device includes a lifting drive 2 and a lifting transmission. Since the main drive shaft and the driven shaft of each group of photovoltaic module conveying devices are rotatably arranged on the frame 9, and the cooling plate lifting mechanisms of each group are fixed on the frame 9 to form a stack cooling table, each group of photovoltaic module cooling mechanisms and each group of photovoltaic module conveying mechanisms are supported by the frame and form a whole with the frame. The lifting drive 2 is connected to the frame 9 through the lifting transmission device, and can drive the photovoltaic module conveying devices and photovoltaic module cooling devices of each group arranged on the frame 9 to rise and fall synchronously. It is best that the lifting drive adopts a driving motor, and the lifting transmission mechanism adopts a chain transmission mechanism. The driving motor is fixedly arranged on the top of the stack frame 18, the chain of the chain transmission device is fixedly connected to the frame 9, and the sprocket 3 is rotatably arranged on the stack frame. The frame 9 can be driven to rise and fall through the synchronous chain transmission mechanism, thereby driving the entire stack cooling table to rise and fall. Of course, the lifting device can also adopt an electric hoist or a winch combined with a pull rope structure, one end of the pull rope is connected to the winch, and the other end is connected to the frame 9.

[0024] Normally, the photovoltaic module cooling stack device is arranged behind the laminating main machine, and the first layer, that is, the topmost synchronous belt, is docked with the discharge side of the conveying component of the laminating main machine. When the module arrives, the photovoltaic module enters the first layer first. After the photovoltaic module enters the first layer, the lifting drive 2 is started, driving the lifting frame 9 to rise, so that the second layer synchronous belt is flush with the conveying component of the incoming material and then stops rising, and so on, until all the modules enter each layer, that is, enter the stack. After the cooling is completed, the lifting drive 2 is started, driving the lifting frame 9 to descend, and all the modules are transported out of the stack.

[0025] The photovoltaic module cooling stack device with this structure can set the corresponding number of layers of synchronous belts and cooling plates according to the number of modules, and make full use of the height of the three-dimensional space to reduce the occupation of the plane space. Since the lamination time of the photovoltaic modules has a relatively stable duration, the photovoltaic modules can be cooled for a corresponding period of time in the photovoltaic module cooling stack device. According to this period of time, the cooling intensity can be reasonably set to synchronize the cooling of the photovoltaic modules with the lamination host, and the rhythm of the two can be kept consistent, ensuring the cooling effect without affecting the production efficiency.
