Description

Technical Field

[0001] The invention relates to the technical field of photovoltaics, in particular to a device for scraping and hot-stamping a photovoltaic module film. Background Art

[0002] In recent years, the call for green development has become increasingly strong worldwide, and the country's energy development strategy has gradually tilted towards clean energy such as photovoltaics, which has led to the rapid development of solar power generation technology. Photovoltaic panels are important components of solar power generation technology. During their production process, a thin film (EVA film) needs to be laid on their surface.

[0003] At present, the existing film flattening solutions include air blowing, manual film laying, and adsorption. The air blowing method refers to adding a set of air exhaust at the inlet of the component flow, and using compressed pore air to flatten the cavity between the film and the glass; manual film laying refers to the method of laying the EVA film on the glass by manual operation; the adsorption method refers to a method of using a vacuum suction cup to absorb the EVA film and re-lay the film.

[0004] There are two methods for bonding EVA film to glass: contact pressing and non-contact pressing. Contact pressing refers to using a heated object to melt the EVA film through heat conduction, and using a certain pressure to adhere the melted film to the glass surface; non-contact pressing refers to using infrared heat sources, high-temperature hot air flow or ultrasonic generators to heat the EVA film through energy transfer to make it adhere to the glass.

[0005] There are disadvantages based on the existing scraping solution:

[0006] Disadvantages of the air blowing method: the air exhaust will cause different pressures and flows at each location due to the length of the air exhaust, which cannot completely eliminate the cavities and will cause the EVA film to shift in a single direction; for EVA film rolls that already have wrinkles, the cavities will still recover after a certain period of time. Disadvantages of manual film laying: time-consuming and labor-intensive; Disadvantages of the adsorption method: cavities will still randomly occur after re-laying the film.

[0007] The existing EVA film and glass adhesion and fixing solution has disadvantages:

[0008] Contact pressing has disadvantages: Due to the characteristics of EVA film, the phenomenon of pressing is often that the film adheres to the pressing workpiece;

[0009] Non-contact ironing has disadvantages: it is easy to cause hidden cracks in the glass, which can make the photovoltaic modules scrapped; the adhesion time of EVA film and glass is not long, and the film and glass will naturally separate after a few minutes to 20 minutes. Equipment with this function needs to ensure that it will not separate for at least 2 hours on standby or remain adhered when the modules are arranged.

[0010] Based on the above issues, this case arose. Summary of the invention

DETAILED DESCRIPTION

[0035] The embodiment of the present invention provides a photovoltaic module film scraping and spot hot processing equipment, such as Figure 1-9 As shown, it includes a conveying assembly, a pneumatic clamp 3, a positioning assembly 4, a supporting assembly 5, a pressing assembly 6, a V-shaped scraper 7 and a scraping assembly 8 arranged on a frame 1;

[0036] The conveyor assembly is used to input the photovoltaic workpiece 9 into the processing area. The conveyor assembly is composed of a plurality of conveyor belts 2, and the plurality of conveyor belts 2 are arranged at a horizontal interval. The conveyor belt 2 is a prior art, and is used to introduce the photovoltaic workpiece 9 with a film laid thereon into the processing area in the frame 1.

[0037] like Figure 1 As shown, due to the poor supporting effect of the conveyor belt 2, in order to prevent the photovoltaic workpiece 9 from being crushed during the hot spot process, a supporting assembly 5 is arranged in the processing area, and a total of four groups of supporting assemblies 5 are arranged, which are located at the bottom of the four corners of the photovoltaic workpiece 9 in the processing area.

[0038] like Figure 7As shown, the supporting assembly 5 includes a bottom plate 51, a top plate 52, a plurality of rectangular springs 53 and a plurality of pulleys 54. The bottom plate 51 is fixed on the frame 1, the plurality of rectangular springs 53 are arranged between the bottom plate 51 and the top plate 52, and the plurality of pulleys 54 are rotatably arranged on the top plate 52 and arranged along the input direction of the photovoltaic workpiece 9. The top surface of the pulley 54 is flush with the transmission belt 2. When the photovoltaic assembly 9 flows in, due to the existence of the pulley 54, the photovoltaic assembly 9 will not contact the top plate 52 of the supporting assembly 5, and will not scratch the glass. When the pressing assembly 6 performs the pressing operation on the photovoltaic workpiece 9, the pressing assembly 6 corresponds to the supporting assembly 5 up and down, and the supporting assembly 5 provides support for the photovoltaic workpiece 9. Through theoretical calculation, the selection of a suitable rectangular spring 53 can play a certain buffering role and provide a certain supporting pressure, so that the melted EVA film can adhere tightly to the glass and will not come off after cooling.

[0039] At the same time, the rectangular spring 53 is provided to make the supporting assembly 5 have a certain flexibility to prevent the photovoltaic workpiece 9 from being crushed.

[0040] like Figure 1 As shown, since the photovoltaic workpiece 9 will be offset when being sent into the processing area, in order to correct the positioning of the photovoltaic workpiece 9, a positioning component 4 is set in the processing area of ​​the frame 1. Two groups of positioning components 4 are set, corresponding to the two sides of the photovoltaic workpiece 9 respectively.

[0041] like Figure 6 As shown, the positioning assembly 4 includes a cylinder 1 41 and a horizontal bar 42. The cylinder 1 41 is horizontally arranged on the frame 1, and the output end is connected to the horizontal bar 42. A plurality of positioning wheels 43 are arranged at longitudinal intervals on the horizontal bar 42. Under normal conditions, two groups of horizontal bars 42 are located on both sides of the photovoltaic workpiece 9. When the photovoltaic workpiece 9 is sent to the processing area, the horizontal bar 42 pushes the photovoltaic workpiece 9 driven by the cylinder 1 41. When the cylinder 1 41 is pushed to the maximum stroke, the spacing between the positioning wheels 43 on the two groups of horizontal bars 42 is the width of the photovoltaic workpiece 9.

[0042] like Figure 2 and Figure 5 As shown, two groups of pneumatic clamps 3 are provided, corresponding to two corners of one side of the photovoltaic workpiece 9. The pneumatic clamps 3 are existing commercially available products, and the model may be HFY32 finger cylinder. After the positioning assembly 4 adjusts the position of the photovoltaic workpiece 9, the pneumatic clamps 3 clamp the side of the photovoltaic workpiece 9.

[0043] like Figure 3 As shown, the scraping assembly 8 is used to drive the V-shaped scraper 7 to move axially back and forth, and the protrusion of the V-shaped scraper 7 faces the scraping direction. The protrusion of the V-shaped scraper 7 is centered on the photovoltaic workpiece 9.

The transverse track 81 is arranged at the top of the frame 1 along the scraping direction. The moving module 82 can drive the moving body 83 to slide on the transverse track 81. The cylinder 2 85 is arranged on the moving body 83 and can drive the V-shaped scraper 7 to rise and fall. The combination of the transverse track 81 and the moving module 82 is a gear rack module or a screw nut module, which is an existing moving module 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 through the moving module 82 and the cylinder 2 85 of the scraping assembly 8, and then moves in a single direction along the upper surface of the photovoltaic workpiece 9 to squeeze the cavity between the film and the glass from the middle to both sides. Finally, the scraping assembly 8 is reset by lifting by the cylinder 2 8. The V-shaped V-shaped scraper 7 can completely eliminate the cavity between the EVA film and the glass, while avoiding the recovery of the cavity.

[0045] like Figure 4 As shown, the scraping assembly 8 also includes a support plate 84, a slide groove 86 is longitudinally provided on the moving body 83, a slider slidably adapted in the slide groove 86 is provided on the support plate 84, a locking bolt 87 corresponding to the panel of the moving body 83 is threadedly connected on the support plate 84, and a cylinder 2 85 is provided on the support plate 84. By providing the slide groove 86, the longitudinal position of the V-shaped scraper 7 can be adjusted to the center position of the photovoltaic workpiece 9, so that it can adapt to different models of photovoltaic workpieces 9.

[0046] There are four groups of pressing components 6, corresponding to the tops of the four corners of the photovoltaic workpiece 9 respectively.

[0047] like Figure 8 As shown, the 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 pressing piece 68. The horizontal rail 61 is fixed on the frame 1. The horizontal movement module 62 can drive the vertical rail 63 to slide horizontally on the horizontal rail 61, the vertical movement module 64 can drive the vertical rail 65 to slide horizontally on the vertical rail 63, and 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 pressing piece 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 rack modules or lead screw nut modules, which are all existing linear motion modules and will not be described in detail.

[0048] like Fig. 9As shown, the pressing piece 68 includes a pressing body 681, an electric heating pipe 683 and four pressing strips 682. The four pressing strips 682 are arranged on the pressing body 681 at equal angles in a circular direction. The electric heating pipe 683 is arranged at the center of the pressing body 681. The electric heating pipe 683 is used to heat the pressing strips 682. The clamping groove 67 can clamp the pressing strips 682. The fixing bolt 69 is threadedly connected to the clamping groove 67 and corresponds to the pressing strips 682. By setting four pressing strips 682, when one of them is worn out during use, it can be removed and rotated 90° before being clamped for use. The use efficiency of one pressing piece 68 is improved and materials are saved.

[0049] Working principle:

[0050] Step 1: The conveyor belt 2 inputs the photovoltaic workpiece 9 into the processing area.

[0051] 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 the center using the positioning component 4 .

[0052] Step three: use the pneumatic clamp 3 close to one side of the V-shaped scraper 7 to clamp the photovoltaic workpiece 9.

[0053] Step 4: The V-shaped scraper 7 is adjusted to the upper surface of the photovoltaic workpiece 9 through the moving module 82 and the second cylinder 85 of the scraping assembly 8, and then moves in one direction along the upper surface of the photovoltaic workpiece 9 to squeeze the cavity between the film and the glass from the middle to both sides. Finally, the scraping assembly 8 is lifted by the second cylinder 8 and reset.

[0054] Step 5: the vertical moving module 66 of the pressing assembly 6 drives the pressing member 68 downward to the upper surface of the photovoltaic workpiece 9 to perform a spot pressing operation on it, and resets it after completion.
