[0034] Referring to Figure 1 and Figure 2 The present embodiment provides a glass assembly for preparing a photovoltaic assembly, the glass assembly comprising a first glass 100 and a blocking strip 110, the blocking strip 110 being removably arranged on the periphery of the front surface of the first glass 100, and the blocking strip 110 being arranged protruding from the periphery of the first glass 100 along the width direction of the blocking strip 110. Wherein, along the width direction of the blocking strip 110, the ratio of the width B1 of the blocking strip 110 removably arranged on the first glass 100 to the width B2 of the blocking strip 110 protruding from the periphery of the first glass 100 is 0.5-1.5. Of course, the ratio of the width B1 of the blocking strip 110 removably arranged on the first glass 100 to the width B2 of the blocking strip 110 protruding from the periphery of the first glass 100 can also be other values, which is not limited by the present embodiment.
[0035] Specifically, the photovoltaic assembly comprises a photovoltaic cell (not shown), a second glass (not shown), and the above-mentioned glass assembly with the blocking strip 110 removed, the first glass 100 of the glass assembly being arranged on the front surface of the photovoltaic cell, the second glass being arranged on the back surface of the photovoltaic cell, and the first glass 100 and the second glass both being pasted to the photovoltaic cell through a glue film. Wherein, the blocking strip 110 on the first glass 100 is removed after lamination of the photovoltaic assembly.
[0036] In the present embodiment, the first glass 100 with the blocking strip 110 removably arranged is pasted to the front surface of the photovoltaic cell through the glue film, and when laminated, the overflowed glue film will be adhered to the blocking strip 110, thereby preventing the overflowed glue film from being adhered to the high-temperature cloth below, and the ratio of the width of the blocking strip 110 removably arranged on the first glass 100 to the width of the blocking strip 110 protruding from the periphery of the first glass 100 is 0.5-1.5, effectively preventing the part of the blocking strip 110 protruding from the periphery of the first glass 100 from being bent towards the back surface of the first glass 100, i.e. preventing the overflowed glue film from being adhered to the high-temperature cloth below due to the bending of the blocking strip 110.
[0037] It can be understood that the adhesive film will overflow between the first glass 100 and the second glass during lamination, and the blocking strip 110 separates the overflowed adhesive film and the high-temperature cloth covering the first glass 100, thereby preventing the overflowed adhesive film from adhering to the high-temperature cloth covering the first glass 100; and the overflowed adhesive film will solidify on the blocking strip 110, that is, the overflowed adhesive film will not drip onto the high-temperature cloth below the second glass. It can be understood that the edge sealing of the photovoltaic module can be completed during the lamination process, thereby improving the production efficiency.
[0038] After lamination, the blocking strip 110 can be separated on the first glass 100, and the blocking strip 110 can be removably arranged on another first glass 100 after being separated on the first glass 100, that is, the blocking strip 110 can be recycled, thereby avoiding waste.
[0039] In addition, the ratio of the width of the blocking strip 110 removably arranged on the first glass 100 to the width of the blocking strip 110 protruding from the periphery of the first glass 100 is 0.5-1.5, which effectively ensures that the blocking strip 110 is firmly connected to the first glass 100 and is convenient to separate.
[0040] It is worth mentioning that, as shown in Figure 2 The glass assembly includes a plurality of first glasses 100 stacked together, and adjacent two first glasses 100 are separated by the blocking strip 110. It can be understood that before the photovoltaic module is assembled, the plurality of first glasses 100 can be stacked together and separated by the blocking strip 110, thereby effectively preventing the adjacent first glasses 100 from directly contacting and breaking.
[0041] Exemplarily, the blocking strip 110 can be arranged on the front periphery of the first glass 100 by pasting; or the blocking strip 110 is provided with a U-shaped structure capable of accommodating the periphery of the first glass 100, and the blocking strip 110 is clamped on the periphery of the first glass 100 by the U-shaped structure. Of course, the blocking strip 110 can also be arranged on the front periphery of the first glass 100 by other means, which is not limited in the present embodiment.
[0042] Exemplarily, the material of the blocking strip 110 is plastic material, which has high mechanical strength and good toughness, and the blocking strip 110 can maintain a good flat state, thereby preventing the part of the blocking strip 110 protruding from the periphery of the first glass 100 from bending towards the second glass, and preventing the overflowed adhesive film from adhering to the high-temperature cloth below the second glass.
[0043] In some embodiments, the back periphery of the second glass can also be removably provided with a blocking strip 110, to further prevent the overflowed adhesive film from dripping onto the high-temperature cloth below the second glass.
[0044] For example, the width B1 of the barrier strip 110 removably disposed on the first glass 100 is 2mm-3mm to ensure that the barrier strip 110 is firmly connected to the first glass 100 and is easy to separate. Of course, the width B1 of the barrier strip 110 removably disposed on the first glass 100 can also be other values, which are not limited in this embodiment.
[0045] For example, the width B2 of the blocking strip 110 protruding from the periphery of the first glass 100 is 2mm-3mm, to prevent the portion of the blocking strip 110 protruding from the periphery of the first glass 100 from bending towards the second glass, and to prevent the adhesive film overflowing between the first glass 100 and the second glass from sticking to the high-temperature cloth. Of course, the width B2 of the blocking strip 110 protruding from the periphery of the first glass 100 can also be other values, which are not limited in this embodiment.
[0046] In some embodiments, the first glass 100 is polygonal, such as rectangular, and each side of the first glass 100 is removably provided with a blocking strip 110, which facilitates the removability of the blocking strip 110 on the first glass 100 and the easy separation of the blocking strip 110 from the first glass 100.
[0047] In one feasible implementation, the two adjacent blocking strips 110 abut against each other, and the blocking strips 110 are more effective in separating the overflowing adhesive film from the high-temperature cloth covering the first glass 100, that is, more effectively preventing the overflowing adhesive film from sticking to the high-temperature cloth above.
[0048] In another feasible implementation, the spacing between two adjacent blocking strips 110 is less than 5 mm, which prevents the overflowing adhesive film from sticking to the high-temperature cloth above, while also making it convenient to remove the blocking strips 110 from the first glass 100.
[0049] In some embodiments, the blocking strip 110 is annular, with its outer ring protruding beyond the periphery of the first glass 100, which better prevents the adhesive film overflowing between the first glass 100 and the second glass from sticking to the high-temperature cloth. It is understood that when the first glass 100 is disc-shaped, the blocking strip 110 is annular; when the first glass 100 is rectangular, the blocking strip 110 is rectangular annular, facilitating the removable installation of the blocking strip 110 on the first glass 100.
[0050] Reference Figure 1 , Figures 3 to 5 As shown, this embodiment also provides a strip removal device for removing the blocking strip 110 of the glass assembly. The strip removal device includes a platform, a pressing component, and a gripping component.

[0052] In the embodiment, first, the photovoltaic assembly provided with the blocking strip 110 in a removable manner is placed on the carrier, and is pressed by the pressing assembly; then the blocking strip 110 is clamped by the clamping jaw 200, and the blocking strip 110 is pulled away from the first glass 100 by the driving mechanism driving the clamping jaw 200, so that the operation efficiency is high and the operation is convenient.
[0053] Exemplarily, for the convenience of removing the blocking strip 110, the second glass of the photovoltaic assembly is placed towards the carrier.
[0054] Specifically, the pressing assembly comprises a plurality of pressing columns 300 arranged at intervals, and the pressing assembly presses the first glass 100, the second glass and the photovoltaic cell on the carrier by the pressing columns 300, so as to uniformly press the photovoltaic assembly and effectively prevent the photovoltaic assembly from being damaged by pressing.

[0056] Specifically, the pressing assembly can further comprise a pressing driving structure (not shown) connected with the pressing column 300, and the pressing driving structure is used to drive the pressing column 300 to move up and down, so that the pressing column 300 extrudes or separates from the first glass 100. In the embodiment, the pressing driving structure corresponds to the pressing column 300 one by one, or one pressing driving structure drives all the pressing columns 300.
[0057] Exemplarily, the pressing driving structure comprises, but is not limited to, a pneumatic cylinder and a motor-driven screw sliding table mechanism.
[0058] Specifically, the clamping jaw 200 comprises an upper clamping plate 210 and a lower clamping plate 220, the clamping jaw 200 clamps the blocking strip 110 by the upper clamping plate 210 and the lower clamping plate 220, and the lower clamping plate 220 is provided with an anti-skid structure 221. In the embodiment, the upper clamping plate 210 extrudes the top surface of the blocking strip 110, and the lower clamping plate 220 extrudes the bottom surface of the blocking strip 110 through the anti-skid structure 221, so as to clamp the blocking strip 110; the lower clamping plate 220 is provided with the anti-skid structure 221, which can increase the friction, so that even if the anti-skid structure 221 clamps the glue film solidified on the blocking strip 110, the blocking strip 110 can also be smoothly pulled away from the first glass 100.
[0059] Exemplarily, the anti-skid structure 221 can be anti-skid lines. Of course, the anti-skid structure 221 can also be a plurality of convex columns arranged side by side, or irregular convex or concave structures, or other structures having an anti-skid effect, and the present embodiment is not limited thereto.
[0060] Exemplarily, the upper clamping plate 210 and the lower clamping plate 220 can each be a rectangular plate to ensure sufficient contact area with the blocking strip 110.
[0061] Specifically, the clamping jaw 200 further comprises a first finger air cylinder (not shown), one of two first clamping fingers of the first finger air cylinder being connected with the upper clamping plate 210, and the other being connected with the lower clamping plate 220. Of course, the upper clamping plate 210 and the lower clamping plate 220 can also be driven by other driving mechanisms to clamp the blocking strip 110, and the present embodiment is not limited thereto.
[0062] Specifically, the grabbing assembly comprises a plurality of clamping jaws 200, which are arranged at intervals around the carrier. In the present embodiment, the plurality of clamping jaws 200 clamp the blocking strip 110 at the same time, i.e. all the blocking strips 110 can be pulled off the first glass 100 at one time, and damage to the blocking strips 110 during the pulling-off process is effectively prevented.
[0063] Exemplarily, when the first glass 100 is rectangular, each long side of the first glass 100 corresponds to three to eight clamping jaws 200, and each short side corresponds to two to six clamping jaws 200, so that the blocking strips 110 can be quickly pulled off the first glass 100, and damage to the blocking strips 110 during the pulling-off process is effectively prevented. For example, each long side of the first glass 100 corresponds to three clamping jaws 200, and each short side corresponds to two clamping jaws 200.
[0064] Specifically, the grabbing assembly further comprises a first driving mechanism (not shown) and a second driving mechanism (not shown), the first driving mechanism being connected with the clamping jaw 200, and the second driving mechanism being connected with the first driving mechanism. In the present embodiment, when it is necessary to pull the blocking strip 110 off the first glass 100, the first driving mechanism is first controlled to drive the clamping jaw 200 to move towards the first glass 100, then the clamping jaw 200 is controlled to clamp the blocking strip 110, and finally the second driving mechanism is controlled to move upwards, so that the blocking strip 110 is pulled off the first glass 100 upwards by the clamping jaw 200, which is convenient to control; after completion, the first driving mechanism and the second driving mechanism are reset to wait for the next round of operation.
