Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, specifically to a hot-heating device for photovoltaic module films to prevent glass from shattering. Background Technology

[0002] In recent years, the call for green development has grown stronger worldwide, and national energy development strategies have gradually shifted towards clean energy sources such as photovoltaics, leading to the rapid development of solar power generation technology. Photovoltaic panels are a crucial component of solar power generation technology, and their production process requires the application of a thin film (EVA film) to their surface.

[0003] Currently, one method for bonding EVA film to glass is non-contact heat transfer. Non-contact heat transfer refers to using devices such as infrared heat sources, high-temperature hot airflow, or ultrasonic generators to heat the EVA film through energy transfer, causing it to adhere to the glass.

[0004] Non-contact heat treatment has disadvantages: due to the high heating temperature and long dwell time, it is easy to cause microcracks in the glass, which will lead to the scrapping of photovoltaic modules; at the same time, the adhesion time between EVA film and glass is not long, about a few minutes to 20 minutes, and the film will naturally detach from the glass. Equipment with this function needs to ensure that it does not detach for at least 2 hours of standby or still maintains adhesion when the modules are arranged.

[0005] This case arose from the aforementioned issues. Utility Model Content

Detailed Implementation

[0028] This utility model embodiment provides a hot-pressing device for photovoltaic module thin films to prevent glass from shattering, such as... Figure 1-9 As shown, it includes a conveying assembly, a pneumatic gripper 3, a positioning assembly 4, a supporting assembly 5, a heat pressing assembly 6, a V-shaped scraper 7, and a leveling assembly 8, all mounted on the frame 1.

[0029] The conveying assembly is used to input the photovoltaic workpiece 9 into the processing area. The conveying assembly consists of several conveyor belts 2, which are arranged laterally at intervals. The conveyor belts 2 are existing technology and are used to guide the photovoltaic workpiece 9 with the thin film applied into the processing area in the frame 1.

[0030] like Figure 1 As shown, due to the poor support effect of the conveyor belt 2, in order to prevent the photovoltaic workpiece 9 from being crushed during the hot stamping process, a support assembly 5 is set in the processing area. There are four sets of support assemblies 5, located at the bottom of the four corners of the photovoltaic workpiece 9 respectively.

[0031] like Figure 7As shown, the support assembly 5 includes a base plate 51, a top plate 52, several rectangular springs 53, and several pulleys 54. The base plate 51 is fixed to the frame 1. The rectangular springs 53 are disposed between the base plate 51 and the top plate 52. The pulleys 54 are rotatably disposed on the top plate 52 and are arranged along the input direction of the photovoltaic workpiece 9. The top surface of the pulleys 54 is flush with the transmission belt 2. When the photovoltaic module 9 flows in, the presence of the pulleys 54 prevents the photovoltaic module 9 from contacting the top plate 52 of the support assembly 5, thus preventing scratching the glass. When the heat pressing assembly 6 heats the photovoltaic workpiece 9, the heat pressing assembly 6 corresponds vertically to the support assembly 5. The support assembly 5 provides support for the photovoltaic workpiece 9. Through theoretical calculations, selecting a suitable rectangular spring 53 can provide a certain amount of cushioning and support pressure, allowing the molten EVA film to adhere tightly to the glass and not detach after cooling.

[0032] Meanwhile, a rectangular spring 53 is provided to give the supporting component 5 a certain degree of flexibility, preventing the photovoltaic workpiece 9 from being crushed.

[0033] like Figure 1 As shown, since the photovoltaic workpiece 9 will shift when it is fed into the processing area, in order to correct and position the photovoltaic workpiece 9, a positioning component 4 is set in the processing area of ​​the frame 1. There are two sets of positioning components 4, which correspond to the two sides of the photovoltaic workpiece 9 respectively.

[0034] like Figure 6 As shown, the positioning component 4 includes a cylinder 41 and a crossbar 42. The cylinder 41 is horizontally mounted on the frame 1, and its output end is connected to the crossbar 42. Several positioning wheels 43 are longitudinally spaced on the crossbar 42. Under normal conditions, the two sets of crossbars 42 are located on both sides of the photovoltaic workpiece 9. When the photovoltaic workpiece 9 is sent into the processing area, the crossbars 42 push the photovoltaic workpiece 9 under the drive of the cylinder 41. When the cylinder 41 pushes to its maximum stroke, the distance between the positioning wheels 43 on the two sets of crossbars 42 is the width of the photovoltaic workpiece 9.

[0035] like Figure 2 and Figure 5 As shown, two sets of pneumatic grippers 3 are provided, corresponding to the two corners of one side of the photovoltaic workpiece 9. The pneumatic grippers 3 are commercially available products, and the model can be HFY32 finger cylinder. After the positioning component 4 adjusts the position of the photovoltaic workpiece 9, the pneumatic grippers 3 clamp the side of the photovoltaic workpiece 9.

[0036] like Figure 3 As shown, the leveling component 8 is used to drive the V-shaped scraper 7 to move axially reciprocally, with the protrusion of the V-shaped scraper 7 facing the leveling direction. The protrusion of the V-shaped scraper 7 is centered on the photovoltaic workpiece 9.

[0037] like Figure 4As shown, the leveling assembly 8 includes a horizontal axis track 81, a moving module 82, a moving body 83, and a second cylinder 85. The horizontal axis track 81 is positioned on the top of the frame 1 along the leveling direction. The moving module 82 can drive the moving body 83 to slide on the horizontal axis track 81. The second cylinder 85 is positioned on the moving body 83 and can drive the V-shaped scraper 7 to rise and fall. The combination of the horizontal axis track 81 and the moving module 82 is a gear and rack module or a lead screw and nut module, which are existing moving modules and will not be described in detail. During operation, the V-shaped scraper 7 is adjusted to the upper surface of the photovoltaic workpiece 9 by the moving module 82 and the second cylinder 85 of the leveling assembly 8, and then moves unidirectionally along the upper surface of the photovoltaic workpiece 9, squeezing the cavity between the film and the glass from the middle to both sides. Finally, the leveling assembly 8 is lifted by the second cylinder 85 and reset. The V-shaped scraper 7 can completely eliminate the cavity between the EVA film and the glass, while preventing the cavity from recovering.

[0038] like Figure 4 As shown, the leveling assembly 8 also includes a support plate 84. A longitudinal groove 86 is formed on the movable body 83. A slider that slides within the groove 86 is provided on the support plate 84. A locking bolt 87 corresponding to the panel of the movable body 83 is threaded onto the support plate 84. A second cylinder 85 is mounted on the support plate 84. By providing the groove 86, the longitudinal position of the V-shaped scraper 7 can be adjusted to the center position of the photovoltaic workpiece 9, enabling it to adapt to different models of photovoltaic workpieces 9.

[0039] There are four sets of heat pressing components 6, which are respectively located above the four corners of the photovoltaic workpiece 9.

[0040] like Figure 8 As shown, the heat pressing assembly 6 includes a horizontal rail 61, a horizontal movement module 62, a vertical rail 63, a vertical movement module 64, a vertical rail 65, a vertical movement module 66, a clamping groove 67, and a heat pressing component 68. The horizontal rail 61 is fixed on the frame 1. The horizontal movement module 62 can drive the vertical rail 63 to slide laterally on the horizontal rail 61. The vertical movement module 64 can drive the vertical rail 65 to slide laterally on the vertical rail 63. The vertical movement module 66 can drive the clamping groove 67 to slide vertically on the vertical rail 65. The clamping groove 67 clamps the heat pressing component 68 through a fixing bolt 69. The combination of the horizontal rail 61 and the horizontal movement module 62, the combination of the vertical rail 63 and the vertical movement module 64, and the vertical rail 65 and the vertical movement module 66 are gear and rack modules or lead screw and nut modules, all of which are existing linear motion modules, and will not be described in detail.

[0041] like Figure 9As shown, the heat press 68 includes a heat press body 681, a heating element 683, and four heat press strips 682. The four heat press strips 682 are arranged circumferentially and at equal angles on the heat press body 681. The heating element 683 is located at the center of the heat press body 681 and is used to heat the heat press strips 682. A clamping groove 67 can hold the heat press strips 682, and a fixing bolt 69 is threaded onto the clamping groove 67 and corresponds to the heat press strip 682. By setting four heat press strips 682, when one of them wears out significantly, it can be removed, rotated 90°, and then clamped for reuse. This improves the efficiency of the heat press 68 and saves materials.

[0042] Working principle:

[0043] Step 1: Conveyor belt 2 inputs photovoltaic workpiece 9 into the processing area.

[0044] Step 2: After the four corners of the photovoltaic workpiece 9 are supported on the four supporting components 5, the position of the photovoltaic workpiece 9 is adjusted to be centered using the positioning component 4.

[0045] Step 3: Use the pneumatic gripper 3 near the V-shaped scraper 7 to clamp the photovoltaic workpiece 9.

[0046] Step four: The V-shaped scraper 7 is adjusted to the upper surface of the photovoltaic workpiece 9 via the moving module 82 of the leveling component 8 and cylinder 85, and then moves unidirectionally along the upper surface of the photovoltaic workpiece 9, squeezing the cavity between the thin film and the glass from the middle to both sides. Finally, the leveling component 8 is lifted by cylinder 8 and reset.

[0047] Step 5: The vertical moving module 66 of the heat pressing component 6 drives the heat pressing part 68 down to the upper surface of the photovoltaic workpiece 9 to perform a spot heat pressing operation, and then resets after completion.

[0048] Step 6: Use conveyor belt 2 to output photovoltaic workpiece 9 from the processing area.
