Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic components, in particular to a cooling device for a lamination outlet of a laminated part and a laminating machine. Background Art

[0002] In the manufacturing process of solar photovoltaic modules, a laminator is required to pressurize and integrate glass panels, EVA (Ethylene Vinyl Acetate) films and cells under vacuum and certain temperature conditions to form a laminate. Therefore, the quality of lamination directly determines the overall quality and performance of the final manufactured solar photovoltaic module.

[0003] At present, after entering the laminator, the edges of the laminated parts are prone to overflowing with EVA residual glue. When discharging, since the EVA glue is in a molten state, the two-chamber discharging of the laminator drives the PTFE cloth to rotate, which will cause the unsolidified EVA residual glue to draw and then fall on the back film of the laminated parts, resulting in indentations, pits and other undesirable degradations of the back film, causing great losses to the production of photovoltaic modules. For such pitting phenomena, production personnel need to regularly replace and clean the PTFE cloth, wasting a lot of time and manpower. In addition, considering that the inside of the laminator is in a continuously high temperature environment, the cooling time required for the laminated parts to enter the discharging table for cooling will be longer, resulting in a large waste of production cycles.

[0025] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0029] As described in the background technology, the laminator is composed of an input stage (A stage), a laminating stage (B stage), an output stage (C stage) and auxiliary equipment. The main body of the laminator is the B stage, which is used to complete the component lamination work. It can include multiple chambers according to different models. Taking the laminator used in this embodiment as an example, the B stage includes two chambers, which are divided into B1 and B2. The B1 stage is the laminating function, and the B2 stage is mainly the curing function. After the laminate is cured, the laminate enters the C stage discharge platform from the second chamber B2.

[0030] At present, after the laminate is laminated by a laminator, EVA glue is easy to overflow from the edge of the laminate, causing the EVA glue to stick to the PTFE cloth, which will be drawn during the lamination process and stick to the PTFE cloth after breaking. After the PTFE cloth is circulated, the residual glue is pressed onto the back film surface of the laminate, resulting in pits and poor degradation.

[0031] Therefore, the utility model solves the above problem by installing the cooling device in this embodiment between the discharge port of the second cavity B2 of the laminator and the C-level discharge platform. The following is a detailed description of a laminate discharge port cooling device provided by this embodiment in conjunction with the accompanying drawings.

[0032] Below, refer to Figure 1 and Figure 2 , an optional implementation scheme according to the present utility model is described in detail.

[0033] The present embodiment provides a cooling device for a laminate discharge port of a laminate, comprising: a plurality of ventilation ducts 1, which are detachably connected to each other and are arranged between a two-cavity discharge port of a laminator and a discharge platform, a plurality of ventilation holes 2 are opened on the ventilation ducts 1, and the ventilation holes 2 face the discharge port of the laminator; at least one air compression device, which is connected to the ventilation ducts 1 and inputs compressed air into the ventilation ducts 1, and the compressed air cools the laminate at the discharge port of the laminator through the ventilation holes 2; and a control unit 3, which is connected to the air compression device and is used to control the air intake of compressed air.

[0034] refer to Figure 1In this embodiment, in order to make the length of the ventilation pipe 1 suitable for all types of laminators in the photovoltaic industry, the length of the ventilation pipe 1 needs to be set longer, which will cause inconvenience in installation and transportation. Therefore, this device adopts a split design, and the ventilation pipe 1 is set into multiple parts and detachably connected to meet the needs of laminators of different sizes. At the same time, since the EVA glue of the laminated parts is easy to overflow from the edge during lamination, the EVA glue in a molten state will stick to the polytetrafluoroethylene cloth as it rotates, so that the laminated parts need to be cooled for a long time on the C-level discharge platform. Therefore, this device sets the ventilation pipe 1 between the discharge port B2 of the second cavity of the laminator and the C-level discharge platform, and blows and cools the discharged laminated parts and polytetrafluoroethylene cloth from below through multiple ventilation holes 2 opened on the surface of the ventilation pipe 1, which effectively shortens the cooling time of the laminated parts on the C-level discharge platform and improves production capacity.

[0035] Based on the above basic scheme, the working principle of this embodiment is as follows: when the discharge port of the second cavity B2 of the laminator starts to discharge, the control unit 3 receives a signal and starts the air compression device, and the air compression device inputs compressed air to the ventilation pipe 1, and the compressed air enters the inner cavity of the ventilation pipe 1 arranged below the discharge port, and then rushes out from the multiple ventilation holes 2 opened on the surface of the ventilation pipe 1, forming multiple air ducts that continuously hit the polytetrafluoroethylene cloth and the laminated parts for cooling, accelerating the cooling and solidification of the EVA residual glue generated during the lamination process, and preventing the EVA overflow glue from being drawn and sticking to the polytetrafluoroethylene cloth during the rotation process, thereby solving the pit problem caused by the EVA residual glue on the back film surface of the laminated part. By adopting the cooling device in this embodiment, the back film indentation, pits and other adverse degradation problems caused by the EVA overflow glue of the laminator can be effectively improved, the production personnel can extend the cycle of cleaning the polytetrafluoroethylene cloth, and the cooling time of the photovoltaic module lamination process can be effectively shortened, and the production efficiency and product quality can be improved.

[0036] In one embodiment, the ventilation holes 2 are arranged on the wall of the ventilation pipe 1 and are evenly distributed along the length direction of the ventilation pipe 1, so that the compressed air passing through the ventilation holes 2 is directed vertically upward to form a plurality of air ducts to directly hit the discharged laminate and the PTFE cloth for cooling. In order to obtain a uniform air volume, the number and hole spacing of the ventilation holes 2 are positively correlated with the length of the ventilation pipe 1, the aperture of the ventilation holes 2 is positively correlated with the diameter of the ventilation pipe 1, and the aperture of each ventilation hole 2 can be the same or different.

[0037] In this embodiment, the distribution length of the ventilation holes 2 is related to the pattern of the laminate, and should be greater than or equal to the side length of the laminate to achieve comprehensive cooling of it. Therefore, the distribution of the ventilation holes 2 located at both ends of the ventilation pipe 1 is different from the distribution of the ventilation holes 2 located in the middle of the ventilation pipe 1.

[0038] Preferably, in order to standardize the production, the hole spacing of each ventilation hole 2 can be set to be equal and evenly distributed along the length direction of the ventilation pipe 1. The number and aperture of the ventilation holes 2 can be set according to the cooling requirements of the laminate. For example, considering that EVA glue is easy to overflow from the edge of the laminate during the lamination process, it is necessary to enhance the cooling effect at both ends of the ventilation pipe 1 to accelerate the solidification of the EVA glue. The aperture of each ventilation hole 2 can be set to be equal. In this way, due to the loss of wind pressure, the air volume of the ventilation holes 2 at both ends of the ventilation pipe 1 will be greater than that in the middle, which can better meet the cooling requirements of the overflowing EVA glue. In addition, the setting of the same aperture and hole spacing is also convenient for standardized production and easy for mass production. Alternatively, when it is necessary to make the cooling wind formed through the ventilation holes 2 to evenly cool all positions of the laminate, the apertures of the ventilation holes 2 can be set to be unequal, and the apertures gradually increase from the two ends of the ventilation pipe 1 to the middle. This setting can prevent the obvious change of the air volume of the pores due to wind pressure loss, and ensure that the air volume out of each ventilation hole 2 is basically the same, and finally form multiple uniform air ducts on the laminate so that all positions of the laminate can be evenly cooled, reducing the occurrence of quality problems such as cracking in the later stage.

[0039] Furthermore, pressure control meters may be provided at both ends of the ventilation pipe 1 to accurately observe and adjust the pressure of the compressed air in the ventilation pipe 1 , thereby adjusting the wind speed of the ventilation hole 2 .

[0040] In one embodiment, the axes of the multiple ventilation pipes 1 are coincident, that is, the center lines of all ventilation pipes 1 are collinear, wherein the diameter of each ventilation pipe 1 is in the range of 10-100 mm, and the length is in the range of 1000-2500 mm; and / or, the total number of the ventilation holes 2 is 50-100, and the distance between two adjacent ventilation holes 2 is 10-60 mm. The connection method between the two includes at least one of bolt connection, threaded connection, snap connection, bonding or riveting.

[0041] It should be noted that the connection between the multiple ventilation pipes 1 can be the above-mentioned methods, but is not limited to the above-mentioned methods, and can also be other connection methods, as long as the multiple ventilation pipes 1 can be connected together in a detachable manner. In addition, the size of each ventilation pipe 1 can be the same or different. For example, considering that EVA glue will overflow from the edge of the component, the cooling effect on the edge of the component can be enhanced by using large diameter ventilation pipes 1 at both ends.

[0042] In this embodiment, the ventilation pipe 1 is made of high-temperature resistant galvanized steel pipe, and a zinc-iron alloy layer is formed on the surface, so that the steel pipe has good oxidation resistance and wear resistance, thereby extending its service life. The number and size of the ventilation pipes 1 can be set and adjusted according to actual use requirements and installation environment, so that the device can be applied to all laminators in the photovoltaic industry and achieve a good cooling effect. For example, if the cooling effect needs to be improved, a large diameter ventilation pipe 1 can be used or the diameter of the ventilation hole 2 can be increased; if it is necessary to facilitate transportation or reduce the occupied space, a small diameter ventilation pipe 1 can be used or the diameter of the ventilation hole 2 can be reduced.

[0043] refer to Figure 2 For the sake of convenience, two ventilation pipes 1 are used as an example below, including a first ventilation pipe 11 and a second ventilation pipe 12. Considering that if the diameter of the ventilation pipe 1 is too small, it will not have a good wind buffering and uniform effect, and if the diameter is too large, a higher pressure of compressed air is required to obtain a more uniform wind wall, and the equipment occupies a large space, it is preferred to use two galvanized steel pipes with a diameter of 20mm and a length of 1770mm for detachable connection. The total length of the ventilation pipe 1 is 3540mm. Preferably, 80 ventilation holes 2 are provided, the hole spacing is 30mm, and the length of the ventilation pipe 1 with holes is 2400mm.

[0044] In one embodiment, multiple ventilation pipes 1 are threadedly connected through a connector 4, and the ports at both ends of the connector 4 are matched with the ports of the ventilation pipes 1 respectively, which can play a role of quick connection and has the advantages of high strength, high sealing and easy installation.

[0045] In this embodiment, the connector 4 adopts a 20mm double internal thread, that is, a 20mm straight pipe joint with two internal thread interfaces, which can be directly connected to two pipes with external threads, and is commonly used for connecting gas or liquid pipelines. In order to realize the connection function of the connector 4 on the two ventilation pipes 1, the ports of the first ventilation pipe 11 and the second ventilation pipe 12 are provided with corresponding 20mm external threads that can be tightly matched with the internal thread interface of the connector 4. By adopting the connector 4, the connection between the first ventilation pipe 11 and the second ventilation pipe 12 can be completed in a short time, reducing installation time and cost, and due to its high strength and sealing characteristics, the safety and stability of the ventilation pipe 1 can be guaranteed, and problems such as leakage and damage can be avoided.

[0046] In one embodiment, in order to allow compressed air to be introduced into the ventilation pipe 1 , at least one air pipe 5 is further included, wherein one end of the air pipe 5 is connected to the air compression device, and the other end is connected to an end of the ventilation pipe 1 away from the connecting piece 4 .

[0047] In this embodiment, in order to ensure the air outlet effect of the ventilation hole 2, compressed air is selected to be input from both sides of the ventilation pipe 1 through air compression equipment. Therefore, two air pipes 5 are respectively connected to the first ventilation pipe 11 and the second ventilation pipe 12 at one end away from the connecting piece 4, and in order to ensure that there is enough space in the ventilation pipe 1 to accommodate compressed air, the diameter of the ventilation pipe 1 is set to be larger than the diameter of the air pipe 5. It is preferred to use a ventilation pipe 1 with a diameter of 20 mm and an air pipe 5 with a diameter of 15 mm.

[0048] In one embodiment, since the trachea 5 and the ventilation pipe 1 are pipes of different specifications, it is necessary to use a specific pipe fitting or adapter to connect the two to ensure the firmness and sealing of the connection, such as a 20mm to 15mm internal thread pipe, with internal threads at both ends for connecting different pipes. Specifically, an adapter 6 is used to achieve the connection between the ventilation pipe 1 and the trachea 5, which can quickly and conveniently connect and disconnect the trachea 5 while ensuring that the gas does not leak, wherein the port at one end of the adapter 6 is detachably connected to the port of the trachea 5, and the other end is detachably connected to the port of the ventilation pipe 1.

[0049] Exemplarily, the adapter 6 can be a pneumatic quick connector, including a mother body and a daughter body, wherein the mother body is usually installed on the air pipe 5, and the daughter body is installed on the ventilation pipe 1, and the mother body and the daughter body are sealed by a sealing gasket to ensure that the gas does not leak. When the air pipe 5 needs to be connected to the ventilation pipe 1, the daughter body is inserted into the mother body, and the stainless steel beads will automatically roll outward, and the valves of the daughter body and the mother body will be disconnected under the action of the valve spring force, and the valves of the daughter body and the mother body will be closed respectively, instantly blocking the flow of fluid; when the air pipe needs to be disconnected, the daughter body is pulled out of the mother body, and the stainless steel beads will automatically return to their original state, and the valves of the daughter body and the mother body will be opened respectively, and the fluid will start to flow again, so that the air pipe 5 can be quickly connected and disconnected.

[0050] In one embodiment, the control unit 3 includes a solenoid valve 31 and a controller, wherein the solenoid valve 31 is a device that uses electromagnetic force to control the opening and closing of the valve, and is arranged on the air pipe 5 to control whether the air pipe 5 is conductive. When the solenoid valve 31 receives a signal sent by the controller, it will open or close the air pipe 5, thereby controlling the intake of compressed air. The controller is a programmable logic controller that can control the operation of various devices through programming. The opening and closing time of the solenoid valve 31 can be controlled by electrically connecting the controller to the solenoid valve 31. When the controller receives the motor signal of the second chamber B2 of the laminator, it will send an instruction to the solenoid valve 31 to control the opening or closing of the air pipe 5. Through the cooperation of the solenoid valve 31 and the controller, the opening and closing of the air pipe 5 can be controlled, thereby achieving a cooling effect on the polytetrafluoroethylene cloth and the laminate.

[0051] Furthermore, the controller can also program and control the switch time of the solenoid valve 31 according to the production process and requirements to achieve a better cooling effect. For example, a temperature sensor can be set at the discharge port to monitor the component temperature, and multiple temperature thresholds can be set to achieve precise control of the switch time of the air pipe 5 and the compressed air flow rate, thereby achieving precise cooling of the component and further improving the cooling effect.

[0052] The present embodiment also discloses a laminator, comprising a cooling device and a bracket for a laminate discharge port of a laminate as described in any of the above schemes, wherein the cooling device is arranged between the second-cavity discharge port of the laminator and the C-level discharge platform through the bracket, and the bracket can be adjusted in height, for example, by adopting a telescopic, threaded lifting mechanism or a cylinder push rod and other devices, and by manual or electric means for lifting and lowering control, the bracket can be adjusted to a suitable working height to meet the requirements for the height adaptability of the cooling device under different working conditions.

[0053] Based on the above structure, the device adopts the first ventilation pipe 11 and the second ventilation pipe 12 for detachable connection. This design can adapt to the requirements of laminators of different sizes and is easy to install and transport. During the installation process, the device is fixed between the discharge port of the second chamber B2 of the laminator and the C-level discharge platform by a height-adjustable bracket, so that the discharged components and the polytetrafluoroethylene cloth can be blown and cooled, thereby reducing the cooling time on the C-level platform. The device is threadedly connected to the first ventilation pipe 11 and the second ventilation pipe 12 through the internal thread interfaces at both ends of the connector 4 to ensure the safety and stability of the ventilation pipe and avoid leakage and damage. Since the ventilation pipe 1 and the air pipe 5 are pipes of different specifications, in order to realize the introduction of compressed air into the ventilation pipe 1, the other ends of the first ventilation pipe 11 and the second ventilation pipe 12 are respectively connected to the air pipe 5 using adapters 6 to achieve quick connection while ensuring that the gas does not leak.

[0054] When the laminate begins to discharge, the motor of the second chamber B2 of the laminator drives the polytetrafluoroethylene cloth to rotate, and the motor transmits a signal to the controller. After receiving the signal, the controller sends an instruction to the solenoid valve 31 to open the air pipe 5 to pass compressed air. At this time, the compressed air will flow to the ventilation pipe 1 through the air pipe 5, and form a uniform air duct through multiple ventilation holes 2 to hit the laminate and the polytetrafluoroethylene cloth for blowing cooling, which effectively shortens the cooling time of the laminate on the C-level discharge platform. At the same time, since the solenoid valve 31 is electrically connected to the controller, the solenoid valve 31 can be accurately controlled by the controller to achieve accurate control of the switching time of the air pipe 5 and the flow rate of compressed air, thereby improving the cooling effect of the laminate. When the cooling time reaches the set value or the discharge port of the second chamber B2 of the laminator stops discharging, the controller will send an instruction to the solenoid valve 31 to close the air pipe 5 and instantly block the flow of compressed air. The laminate after cooling treatment will be output from the discharge port of the second chamber B2 of the laminator to the C-level discharge platform to complete the entire cooling process.

[0055] This embodiment is based on the above scheme, and the experimental data under the same experimental conditions are shown in the following table:

[0056] Table 1 Comparison of laminator outlet temperature test

[0057]

[0058] As shown in Table 1, the temperature of the B2 discharge laminate after the device is installed is 5.6°C lower than the average temperature of the laminate when it is not installed, and the temperature of the polytetrafluoroethylene cloth is 10°C lower than the average temperature when it is not installed.

[0059] In summary, this embodiment has the following effects based on the above solution:

[0060] 1) Avoid the PTFE cloth from rotating when the EVA glue is in a molten state, which will cause the unsolidified EVA residual glue to be drawn and then fall on the back film of the module, resulting in poor degradation such as indentations and pits on the back film, causing great losses to the production of photovoltaic modules;

[0061] 2) Extend the cleaning cycle of PTFE cloth for production personnel and save time;

[0062] 3) Effectively shorten the cooling time of laminated parts on the C-level discharge platform and improve production capacity.

[0063] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
