Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic modules, and in particular to a curing tool for lightweight photovoltaic modules. Background Art

[0002] During production, lightweight photovoltaic modules need to be cured after the glue bonding layer structure. However, lightweight photovoltaic modules are different from traditional photovoltaic modules. The junction boxes on them usually protrude from the panels of the lightweight photovoltaic modules. It is not easy to stack multiple lightweight photovoltaic modules during curing. Therefore, lightweight photovoltaic modules are usually placed in frame modules for stacking, and then placed in a curing box for curing.

[0003] When the frame components are stacked, the friction between the upper frame and the lower frame is too small, and slippage and overturning are likely to occur during transportation. Currently, these methods are generally used to manually place anti-slip tooling, sandblast the frame surface, and stick tape on the frame surface. However, these methods have the problem that the frames are not firmly fixed and are difficult to disassemble. Utility Model Content

[0004] In order to overcome the problems existing in the prior art, the present application provides a curing tool for lightweight photovoltaic modules.

[0007] By adopting the above technical solution, a glass back panel is installed in the card slot on the inner side of the frame distributed in a rectangular ring shape in the curing tooling, so that the lightweight photovoltaic module to be cured is placed on the glass back panel in the frame. The inner side of the frame above the card slot adopts a bevel design, which can prevent the lightweight photovoltaic module from rubbing against the inner side of the frame during the process of entering and exiting and causing damage. In addition, the first limiting portion provided on the top surface of the frame and the second limiting portion on the bottom surface can cooperate to perform limited stacking, and the top and bottom surfaces of adjacent frames do not need to leave a gap when connected, thereby increasing the number of frames stored in the curing box of the same volume and improving the curing efficiency. The ventilation holes provided on the bevel are used to promote air circulation during the curing process, improve the curing effect, avoid relative slippage between adjacent frames, ensure a secure connection and facilitate disassembly between frames.

[0008] Preferably, gaps are provided between the glass back plate and the inner side surface and the upper and lower surfaces of the card slot, and the buffer layer filled in the gap is a silicone layer.

[0009] By adopting the above technical solution, the gap between the glass back panel and the card slot can provide space when the frame and the glass back panel expand due to heat, and the buffer layer provided in the gap can slow down the relative displacement between the two, reduce the vibration of the lightweight photovoltaic components placed on the glass back panel, and improve the service life of the glass back panel and the frame.

[0010] Preferably, the ventilation holes opened on the inclined surface are arranged in a horizontal array on the frame, and reinforcing ribs are installed between the ventilation holes.

[0011] Preferably, the reinforcing rib connects the inner side of the top of the inclined surface and the top surface of the slot, and the bottom of the reinforcing rib is connected to an end of the top of the slot away from the notch.

[0012] By adopting the above technical solution, the ventilation holes on the inclined surface are used to promote the flow of air during the curing process and improve the curing effect, and reinforcing ribs are arranged between the ventilation holes to connect the top inner side of the inclined surface and the top surface of the card slot respectively. The triangular structure formed by the reinforcing ribs, the inclined surface and the top of the card slot can improve the overall strength of the frame and avoid deformation during the stacking and lamination process.

[0013] Preferably, the first limiting portion is a downwardly concave groove, and the second limiting portion is a downwardly protruding block adapted thereto.

[0014] Preferably, the groove is a groove body with a semicircular cross section, and the protrusion is a protrusion with a semicircular cross section that matches the groove body.

[0015] By adopting the above technical solution, the semicircular groove adopted by the first limiting portion cooperates with the protrusion adapted thereto on the second limiting portion, and the semicircular structure can facilitate the rapid positioning and cooperation between two adjacent frames.

[0016] Preferably, the widths of the top surface and the bottom surface of the frame are both smaller than the width of the entire frame, and the free end of the top surface is provided with a curling edge that rotates toward the inside of the frame.

[0017] By adopting the above technical solution, the smaller widths of the top and bottom surfaces of the frame can reduce the use of frame materials and reduce costs while still achieving the function, and the curled edge set at the free end of the top surface can be easily clamped to avoid scratches on the operator or the clamping part of the robot.

[0018] Preferably, the frame is composed of frame beams on all four sides, wherein the frame beams are all integrally formed metal frame beams.

[0019] By adopting the technical scheme, the frame is assembled by the metal frame beams integrally formed around and assembled with the glass backboard into the clamping groove of the frame, thereby improving the stability of the overall structure of the curing tool.

[0020] To sum up, the present application has at least one of the following beneficial technical effects:

[0021] 1. The present application promotes air circulation during the curing process through the ventilation holes on the inclined surface, without leaving gaps between adjacent upper and lower frames for ventilation, which can increase the number of stored frames in the same volume of curing box, improve the curing efficiency on the production line while ensuring the curing effect.

[0022] 2. The present application can facilitate the quick positioning and cooperation between the two adjacent frames through the groove with a semicircular cross-section on the top surface and the protrusion with a semicircular cross-section on the bottom surface, thereby avoiding relative slipping between adjacent frames, ensuring the connection is firm and facilitating the disassembly of the frames.

[0028] The present application discloses a curing tool for a lightweight photovoltaic module.

[0029] Reference Figure 1 , Figure 2 and Figure 3A curing tool for a lightweight photovoltaic module includes a frame 1 and a glass back panel 2 placed in the frame 1; the frame 1 is distributed in a rectangular ring shape as a whole, wherein a card slot 11 for clamping the glass back panel 2 is opened at the lower inner side of the frame 1, and a buffer layer 111 is provided between the glass back panel 2 and the card slot 11, and an outward inclined slope 12 is adopted from the opening of the card slot 11 to the top of the frame 1, and a ventilation hole 121 is opened on the slope 12; a first limiting portion 13 is provided on the top surface 15 of the frame 1, and a second limiting portion 14 is provided on the bottom surface 16 of the frame 1, wherein the first limiting portion 13 on the top surface 15 and the second limiting portion 14 on the bottom surface 16 of the frame 1 are limited and matched when stacking. In the curing tooling, a glass back panel 2 is installed in a slot 11 on the inner side of the frame 1 that is distributed in a rectangular ring shape, so that the lightweight photovoltaic module to be cured is placed on the glass back panel 2 in the frame 1. The inner side of the frame 1 above the slot 11 is designed with a slope 12 to prevent the lightweight photovoltaic module from rubbing against the inner side of the frame 1 during the process of entering and exiting, thereby preventing damage to the lightweight photovoltaic module. In addition, the first limiting portion 13 on the top surface 15 of the frame 1 and the second limiting portion 14 on the bottom surface 16 can cooperate to perform limited stacking. The top surface 15 and the bottom surface 16 between adjacent frames 1 do not need to leave a gap, thereby increasing the number of frames 1 stored in the curing box of the same volume and improving the curing efficiency.

The gaps between the glass back panel 2 and the slot 11 provide space for the frame 1 and the glass back panel 2 to expand due to heat. Furthermore, the buffer layer 111 provided in the gaps can mitigate relative displacement between the frame 1 and the glass back panel 2, reducing vibrations experienced by the lightweight photovoltaic modules placed on the glass back panel 2 and thereby extending the service life of the glass back panel 2 and the frame 1.

[0031] Reference Figure 1 、 Figure 2 and Figure 3The ventilation holes 121 on the inclined surface 12 are arranged in a horizontal array on the frame 1, and reinforcing ribs 122 are installed between the ventilation holes 121.

The groove is a semicircular groove, and the bump is a matching semicircular bump. The semicircular groove of the first stopper 13 cooperates with the matching bump on the second stopper 14. The semicircular structure facilitates quick positioning and matching between two adjacent frames 1.

The smaller widths of the top surface 15 and the bottom surface 16 of the frame 1 can reduce the use of material for the frame 1 while still achieving its function, thereby reducing costs. In addition, the curling edge 151 provided at the free end of the top surface 15 makes it easier to pick up and clamp, avoiding scratches on the operator or the clamping portion of the robot.

[0034] Reference Figure 1 The frame 1 is composed of frame beams on all sides, and the frame beams are all integrally formed metal frame beams. The frame 1 is assembled with the metal frame beams integrally formed on all sides and assembled with the glass back panel 2 into the card slot 11 of the frame 1 to improve the stability of the overall structure of the curing tooling.
