Description

Technical Field

[0001] This application relates to the field of photovoltaic equipment, specifically a laminator feeding device and laminator equipment. Background Technology

[0002] Lamination is a crucial step in the production of photovoltaic modules, and it is accomplished using a laminator. Before lamination, the photovoltaic modules to be laminated are fed into the laminator using a laminator feeding device.

[0003] Existing laminator feeding devices can only feed and transport photovoltaic modules. The initial temperature of the photovoltaic modules entering the laminator is room temperature. The laminator needs to heat the photovoltaic modules to a predetermined temperature before it can perform lamination, resulting in long working time and low efficiency of the laminator. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a laminator feeding device, the detailed technical solution of which is as follows:

[0005] A laminator feeding device includes a heating mechanism and a conveying mechanism, wherein:

[0006] A heating channel is formed within the heating mechanism, which includes a heating component.

[0007] The conveying mechanism is located inside the heating channel and has a conveying surface to carry the photovoltaic modules to be laminated;

[0008] The conveying mechanism is used to convey the photovoltaic module to the heating channel along the first direction via the conveying surface. The heating module is used to heat the photovoltaic module located in the heating channel. The conveying mechanism is also used to output the heated photovoltaic module from the heating channel along the first direction via the conveying surface.

[0009] The laminator feeding device provided in this application, before conveying the photovoltaic modules to be laminated to the laminator, first conveys the photovoltaic modules to a heating mechanism for preheating, so that the temperature of the photovoltaic modules reaches a predetermined value. The conveying mechanism then conveys the preheated photovoltaic modules to the laminator. In this way, the heating time of the photovoltaic modules in the laminator can be reduced, thereby shortening the working time of the laminator and improving the lamination efficiency.

[0010] In some embodiments, the heating mechanism further includes a mounting frame, a top wall, a first side wall, and a second side wall, wherein: the top wall is disposed on the mounting frame and located above the conveying mechanism; the first side wall and the second side wall are spaced apart on the mounting frame along a second direction, the second direction being perpendicular to the first direction; the top wall, the first side wall, and the second side wall together form a heating channel; a heating component is disposed on the mounting frame and located within the heating channel, the heating component being used to heat the photovoltaic module located within the heating channel.

[0011] The top wall, the first side wall, and the second side wall together form a heating channel that is closed on all sides and open at both ends. On the one hand, this allows the heating mechanism to smoothly transport the photovoltaic modules into the heating channel and output the heated photovoltaic modules from the heating channel. On the other hand, it can reduce heat loss and improve preheating efficiency.

[0012] In some embodiments, the heating assembly includes a plurality of heating units spaced apart on the mounting frame along a first direction. The conveying mechanism is configured to convey a plurality of photovoltaic modules into the heating channel at a time. The heating units are positioned vertically opposite to the plurality of photovoltaic modules located in the heating channel. Each heating unit is configured to independently heat the corresponding photovoltaic module below it.

[0013] Several heating units can simultaneously heat multiple photovoltaic modules located within the heating channel, improving preheating efficiency. Furthermore, since each heating unit independently heats its corresponding photovoltaic module, heating flexibility is enhanced, ensuring that each photovoltaic module is heated to the predetermined temperature.

[0014] In some embodiments, the heating mechanism further includes a controller and temperature sensors corresponding to each heating unit, wherein: the temperature sensors and each heating unit are signal-connected to the controller; the temperature sensors are mounted on the mounting bracket and positioned close to the corresponding heating unit, each temperature sensor measures the temperature of each photovoltaic module located in the heating channel and sends the obtained temperature value of each photovoltaic module to the controller; when the controller determines that the temperature of the photovoltaic module has reached a predetermined value, it controls the corresponding heating unit to stop heating.

[0015] By coordinating the controller and temperature sensor, precise heating control of each heating unit can be implemented to ensure that each heating unit heats the corresponding photovoltaic modules to a uniform predetermined temperature.

[0016] In some embodiments, the temperature sensor is a non-contact infrared temperature sensor or a thermal radiation pyrometer.

[0017] By using a non-contact infrared temperature sensor or a thermal radiation pyrometer as the temperature sensor, non-contact temperature measurement of photovoltaic modules is achieved, avoiding interference between the temperature sensor and the photovoltaic modules.

[0018] In some embodiments, the heating unit includes a plurality of infrared lamps or electric heating tubes arranged in a matrix.

[0019] By using several infrared lamps or electric heating tubes arranged in a matrix as heating units, uniform heating of photovoltaic modules can be achieved, thereby improving the temperature uniformity of photovoltaic modules.

[0020] In some embodiments, a reflector is provided above each infrared lamp or electric heating tube, and the extending direction of the reflector is consistent with the extending direction of the infrared lamp or electric heating tube inside the reflector; the reflector is used to reflect the light illuminating it downwards.

[0021] By setting up a reflector, the light emitted upwards and to both sides by the infrared lamps or electric heating tubes can be reflected downwards onto the photovoltaic modules, thereby reducing light loss and improving preheating efficiency.

[0022] In some embodiments, the mounting bracket includes a fixed bracket and a movable bracket, wherein: a first sidewall and a second sidewall are both disposed on the fixed bracket; the movable bracket is vertically connected to the fixed bracket and is located above the conveying mechanism; a top wall and a heating component are both disposed on the movable bracket, and the heating component is located below the top wall; the heating mechanism further includes a lifting component, which is disposed on the fixed bracket and is drively connected to the movable bracket, and the lifting component is used to drive the movable bracket to rise and fall.

[0023] The height of the top wall and heating components can be adjusted, making this application compatible with photovoltaic modules of various thicknesses. The movable support, top wall, and heating components can also be raised via a lifting mechanism to create space for the operator to replace the silicone plates or other components of the laminator.

[0024] In some embodiments, the top wall is an insulation board, and the first and second side walls are both insulation curtains that are suspended on the mounting frame and can be opened outwards, with the central area of ​​the insulation curtain being a transparent area.

[0025] The top wall is made of insulation board, while the first and second side walls are insulated curtains, further reducing heat loss. Furthermore, since the insulated curtains can be opened outwards, operators can easily access them to replace silicone plates or other components of the laminator. The central area of ​​the insulated curtains is transparent, facilitating observation of the photovoltaic modules within the heating channel.

[0026] This application also provides a lamination apparatus, including a laminator and a laminator feeding device as described in any of the above claims, wherein: the discharge end of the conveying mechanism of the laminator feeding device is connected to the feed end of the laminator; the heating mechanism preheats the photovoltaic module to be laminated located on the conveying mechanism, and the conveying mechanism conveys the preheated photovoltaic module to the laminator; the laminator is used to perform lamination processing on the photovoltaic module.

[0027] The lamination equipment provided in this application preheats the photovoltaic modules during the feeding process of the laminator before laminating them, thereby shortening the lamination time and improving the lamination efficiency. Attached Figure Description

[0038] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0039] As described in the background section, existing laminator feeding devices can only feed and transport photovoltaic modules. The initial temperature of the photovoltaic modules entering the laminator is room temperature. The laminator needs to heat the photovoltaic modules to a predetermined temperature before it can perform lamination, resulting in long working time and low efficiency of the laminator.

[0040] In view of this, this application provides a laminator feeding device that preheats the photovoltaic modules before they are transported to the laminator, thereby shortening the working time of the laminator and improving the lamination efficiency.

[0041] like Figures 1 to 2 As shown, the laminator feeding device provided in this application includes a heating mechanism 1 and a conveying mechanism 2, wherein:

[0042] Heating mechanism 1 has a heating channel formed inside it, and heating mechanism 1 includes heating component 15.

[0043] The conveying mechanism 2 is located inside the heating channel and has a conveying surface that carries the photovoltaic module 100 to be laminated.

[0044] The conveying mechanism 2 is used to convey the photovoltaic module 100 along a first direction (such as the X direction) to the heating channel via the conveying surface. The heating component 15 is used to heat the photovoltaic module 100 located in the heating channel. The conveying mechanism 2 is also used to output the heated photovoltaic module 100 from the heating channel along the first direction via the conveying surface.

[0045] The laminator feeding device provided in this application, before conveying the photovoltaic module 100 to be laminated to the laminator, first conveys the photovoltaic module 100 to the heating channel of the heating mechanism 1 for preheating, so that the temperature of the photovoltaic module 100 reaches a predetermined value. The conveying mechanism 2 then conveys the preheated photovoltaic module 100 to the laminator. In this way, the heating time of the photovoltaic module 100 by the laminator can be reduced, thereby shortening the lamination time of the laminator and improving the lamination efficiency of the laminator.

[0046] For example, if the initial temperature of the photovoltaic module 100 is 25°C, it needs to be heated to 110°C during the lamination process. The laminator feeding device of this application preheats the photovoltaic module 100 during the feeding process, ensuring that the temperature of the photovoltaic module 100 reaches 55°C before entering the laminator.

[0047] In addition, under the set working rhythm, the photovoltaic modules 100 of the current batch must wait for a predetermined time on the laminator feeding device. Only after the laminator has finished opening the cover and output the photovoltaic modules 100 of the previous batch inside can they enter the laminator.

[0048] Therefore, the laminator feeding device of this application can complete the preheating of the photovoltaic module 100 within the waiting time, without needing to spend extra time on preheating. Therefore, the lamination efficiency of this application will not be affected by preheating.

[0049] like Figure 1 As shown, optionally, the heating mechanism 1 further includes a mounting frame 11, a top wall 12, a first side wall 13, and a second side wall 14, wherein: the top wall 12 is disposed on the mounting frame 11 and located above the conveying mechanism 2; the first side wall 13 and the second side wall 14 are disposed at intervals on the mounting frame 11 along a second direction (such as the Y direction), and the second direction is perpendicular to the first direction.

[0050] The top wall 12, the first side wall 13, and the second side wall 14 together form a heating channel. The heating component 15 is mounted on the mounting frame 11 and located within the heating channel. The heating component 15 is used to heat the photovoltaic module 100 located within the heating channel.

[0051] This configuration creates a heating channel that is closed on all sides and open at both ends. On the one hand, it allows the heating mechanism 1 to smoothly transport the photovoltaic module 100 into the heating channel and output the heated photovoltaic module 100 from the heating channel. On the other hand, it reduces heat loss and improves preheating efficiency.

[0052] like Figures 3 to 4 As shown, optionally, the heating component 15 includes a plurality of heating units 18 (e.g., 8 in the figure) spaced apart on the mounting frame 11 along a first direction. The conveying mechanism 2 is configured to convey a plurality of photovoltaic modules 100 into the heating channel each time. The heating units 18 are one above one with the plurality of photovoltaic modules 100 located in the heating channel. Each heating unit 18 is configured to independently heat the corresponding photovoltaic module 100 below it.

[0053] For example, the number of photovoltaic modules 100 preheated each time in the heating channel can be the same as the number of photovoltaic modules 100 that the laminator can perform lamination processing each time.

[0054] With this configuration, several heating units 18 can simultaneously heat several photovoltaic modules 100 located within the heating channel, improving preheating efficiency. Furthermore, since each heating unit 18 independently heats its corresponding photovoltaic module 100, the heating flexibility of each heating unit 18 is enhanced, ensuring that each photovoltaic module 100 is heated to a predetermined temperature (e.g., 55°C).

[0055] Optionally, the heating mechanism 1 further includes a controller and temperature sensors 111 corresponding to each heating unit 18, wherein the temperature sensors 111 and each heating unit 18 are signal-connected to the controller. The temperature sensors 111 are mounted on the mounting bracket 11 and positioned close to the corresponding heating unit 18. Each temperature sensor 111 measures the temperature of each photovoltaic module 100 located within the heating channel and sends the acquired temperature value of each photovoltaic module 100 to the controller. When the controller determines that the temperature of the photovoltaic module 100 has reached a predetermined value, it controls the corresponding heating unit 18 to stop heating.

[0056] Through the cooperation of the controller and the temperature sensor 111, precise heating control of each heating unit 18 can be implemented to ensure that each heating unit 18 heats the corresponding photovoltaic module 100 to a uniform predetermined temperature (e.g., 55°C), thus ensuring the temperature consistency of each photovoltaic module 100 entering the laminator.

[0057] The temperature sensor 111 can be a non-contact infrared temperature sensor or a thermal radiation pyrometer.

[0058] By using a non-contact infrared temperature sensor or a thermal radiation pyrometer as the temperature sensor 111, non-contact temperature measurement of the photovoltaic module 100 is achieved, avoiding contact interference between the temperature sensor 111 and the photovoltaic module 100.

[0059] like Figure 4 As shown, optionally, the heating unit 18 includes a plurality of infrared lamps 16 (e.g., 9 in the figure) arranged in a matrix, or an electric heating tube may be used.

[0060] By using several infrared lamps 16 or electric heating tubes arranged in a matrix as heating units 18, uniform heating of the photovoltaic module 100 can be achieved, thereby improving the temperature uniformity of the photovoltaic module 100 after preheating.

[0061] Optionally, a reflector 17 is provided above each infrared lamp 16 or electric heating tube. The extending direction of the reflector 17 is consistent with the extending direction of the infrared lamp 16 or electric heating tube inside the reflector 17. For example, the reflector 17 and the infrared lamp 16 or electric heating tube inside the reflector 17 both extend along a second direction (such as the Y direction). The reflector 17 is used to reflect the light illuminating it downwards.

[0062] By setting up the reflector 17, the light emitted upward and to both sides by the infrared lamp tube 16 or the electric heating tube can be reflected downward to the photovoltaic module 100, thereby reducing light loss and improving preheating efficiency.

[0063] like Figure 5 As shown, optionally, the reflector 17 includes a top reflector 171, a first side reflector 172, and a second side reflector 173. The top reflector 171 is horizontally positioned directly above the corresponding infrared lamp 16 or electric heating element. The first side reflector 172 and the second side reflector 173 are respectively connected to the two sides of the top reflector 171, forming an angle greater than 90° with both the first side reflector 172 and the second side reflector 173. The top reflector 171 reflects the upward-emitted light from the infrared lamp 16 or electric heating element downwards onto the photovoltaic module 100, while the first side reflector 172 and the second side reflector 173 reflect the light emitted from the infrared lamp 16 or electric heating element to the sides downwards onto the photovoltaic module 100.

[0064] Of course, reflector 17 can also be other existing lamp reflector structures, such as arc reflector, V-shaped reflector, etc.

[0065] like Figures 3 to 4As shown, optionally, the mounting bracket 11 includes a fixed bracket (not shown) and a movable bracket 19, wherein: the first side wall 13 and the second side wall 14 are both disposed on the fixed bracket, and the movable bracket 19 is vertically connected to the fixed bracket and is located above the conveying mechanism 2. The top wall 12 and the heating component 15 are both disposed on the movable bracket 19, and the heating component 15 is located below the top wall 12. The heating mechanism 1 also includes a lifting component 110, which is disposed on the fixed bracket and is drively connected to the movable bracket 19. The lifting component 110 is used to drive the movable bracket 19 to rise and fall.

[0066] By mounting the top wall 12 and heating component 15 on the movable support 19, the height of the top wall 12 and heating component 15 can be adjusted, thereby enabling this application to be compatible with photovoltaic modules 100 of various thicknesses.

[0067] In addition, when it is necessary to replace other parts such as the silicone plate in the laminator, it is usually necessary to use the space on the conveying mechanism 2. Therefore, this application can drive the movable support 19, the top wall 12 and the heating component 15 to rise through the lifting assembly 110 to make room for the operator to replace the silicone plate or other parts of the laminator.

[0068] The lifting assembly 110 can employ various existing linear drive components capable of driving the movable support 19 to rise and fall, such as a guide rod cylinder. The guide rod cylinder itself has a guide rod, which can guide the rise and fall of the movable support 19, thus eliminating the need for additional slide rail pairs. Of course, to ensure the smoothness of the rise and fall of the movable support 19, multiple lifting assemblies 110 can be arranged along the circumference of the movable support 19. These multiple lifting assemblies 110 cooperate with each other to synchronously drive the rise and fall of the movable support 19. Figure 1 As shown, a total of 6 guide rod cylinders are provided, 3 of which are located on one side of the movable bracket 19, and the other 3 are located opposite each other on the other side of the movable bracket 19 to ensure that the movable bracket 19 can be raised and lowered smoothly.

[0069] Optional, such as Figure 4 As shown, the temperature sensor 111 is suspended from the movable bracket 19 via the suspension bracket 112. This allows the temperature sensor 111 to be closer to the photovoltaic module 100, thereby ensuring the accuracy of temperature measurement. When the operator needs to replace the silicone plate or other components of the laminator, the temperature sensor 111 can also be raised via the lifting component 110 to make room and avoid interference between the temperature sensor 111 and the suspension bracket 112.

[0070] Optionally, the top wall 12 is an insulation board, and the first side wall 13 and the second side wall 14 are both insulation curtains that are suspended on the mounting frame 11 and can be opened outwards, with the central area of ​​the insulation curtain being a transparent area.

[0071] By configuring the top wall 12 as an insulation board and the first side wall 13 and the second side wall 14 as insulation curtains, heat loss can be further reduced. In addition, since the insulation curtains can be opened outwards, the operator can use this opening to assist in replacing the silicone plates or other components of the laminator.

[0072] The central area of ​​the insulation curtain is transparent, which makes it easy to observe the heating, operation, or other conditions of the photovoltaic module 100 in the heating channel.

[0073] This application also provides a lamination apparatus, including a laminator and a laminator feeding device as described in any of the above embodiments, wherein: the discharge end of the conveying mechanism 2 of the laminator feeding device is connected to the inlet end of the laminator. A heating mechanism 1 preheats the photovoltaic module 100 to be laminated located on the conveying mechanism 2, and the conveying mechanism 2 conveys the preheated photovoltaic module 100 to the laminator. The laminator is used to perform lamination processing on the photovoltaic module 100.

[0074] The conveying mechanism 2 in the laminator feeding device of this application can be connected to the feed end of the internal conveyor line of the laminator to transport the photovoltaic module 100. The laminator uses existing equipment, and its specific structure is not described here.

[0075] The lamination equipment provided in this application preheats the photovoltaic module 100 during the feeding process of the laminator before laminating the photovoltaic module 100, thereby shortening the lamination time and improving the lamination efficiency.

The scope of protection claimed in this application is defined by the claims, not by the above descriptions in the embodiments.
