Description

Technical Field

[0001] The present application relates to the field of photovoltaic modules, and in particular to a film laminating device, a string spacing film laminating machine, and a film laminating machine system. Background Art

[0002] Photovoltaic modules usually consist of a backplane, a glass plate covering the backplane, and multiple cells located between the two. In order to improve the light energy utilization rate of photovoltaic modules, reflective films are usually pasted at the gaps between the cells to reflect the light energy irradiated to the gaps between the cells onto the glass plate, and then reflected to the cells through the glass plate, so as to make full use of the light energy in the gaps between the cells.

[0003] In a conventional film pasting device, multiple film pasting components are connected to a support frame, and the support frame can move along a preset direction, thereby driving the multiple film pasting components to adhere film strips along the preset direction. Since the multiple film pasting components move with the same support frame, the film strips adhered by the multiple film pasting components have the same length. However, in actual applications, for film pasting components at different positions on the support frame, film strips of different lengths may need to be adhered, and conventional film pasting devices cannot achieve the goal of attaching film strips of different lengths in the same direction at one time.

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] Figure 1 FIG. 1 is a schematic structural diagram of a first film-sticking assembly provided by an exemplary embodiment of the present application. Figure 2 FIG. 1 is a schematic diagram of the structure of a driving unit provided by an exemplary embodiment of the present application. Figure 3a FIG. 1 is a schematic diagram of the structure of a photovoltaic module obtained after a film tape is attached to a photovoltaic module according to an exemplary embodiment of the present application. Figure 4 Shown is a schematic structural diagram of a film sticking device provided by an exemplary embodiment of the present application.

[0030] like Figure 1 , Figure 2 , Figure 3a and Figure 4 As shown, an embodiment of the present application provides a film-attaching device 400, comprising: at least one first film-attaching assembly 100, configured to attach a film tape to the upper surface of a photovoltaic assembly 200; a first driving assembly 300, configured to drive at least one first film-attaching assembly 100 along a first direction (such as Figure 3aThe first film pasting assembly 100 includes: a first support member 130 connected to the first driving assembly 300; a film pasting unit 110, configured to adhere the film tape to the upper surface of the photovoltaic assembly 200; a driving unit 120, connecting the first support member 130 and the film pasting unit 110, and configured to drive the film pasting unit 110 to move along the first direction to extend the attachment range of the film tape along the first direction.

[0031] Specifically, the first driving component 300 can drive at least one first film pasting component 100 to move a certain distance, that is, drive the film pasting unit 110 on at least one driving component 300 to move a certain distance. On this basis, the driving unit 120 can drive the film pasting unit 110 to move again. If the film pasting device has multiple first film pasting components 100, the driving units 120 in the multiple first film pasting components 100 can drive the film pasting unit 110 to move different displacements, so that the total displacement lengths of the multiple film pasting units 110 are different, so that film strips of different lengths can be attached.

[0032] Since the driving unit 120 in the first film sticking assembly 100 can drive the film sticking unit 110 to move along the first direction, thereby adjusting the film sticking length of the first film sticking assembly 100, therefore, when there are at least two first film sticking assemblies 100 in the film sticking device 400, the driving units 120 in the at least two first film sticking assemblies 100 can be controlled to make the film sticking lengths of the film sticking units 110 in the at least two first film sticking assemblies 100 different, thereby improving the film sticking flexibility of the film sticking device 400 and enabling the film sticking device 400 to perform film sticking for scenarios where film strips of different lengths are attached along the first direction.

[0033] Figure 5 The figure shows the structure of a conventional photovoltaic module obtained by attaching a film tape to a conventional film-attached module. Figure 5 As shown, in the related art, the first film tape 20 is usually attached along a first direction by a string spacing film attaching machine, and then the second film tape 30 is attached along a second direction perpendicular to the first direction by a sheet spacing film attaching machine. Since the plurality of first film tapes 20 are of equal length and the plurality of second film tapes 30 are of equal length, the first film tape 20 and the second film tape 30 will overlap at the edge area of ​​the traditional photovoltaic module 10 (i.e. Figure 5 The position shown by the dotted box in the figure) makes the second film tape 30 pasted on the top in the overlapping area not firmly pasted and easily falls off, thereby reducing the process quality.

[0034] In some embodiments, Figure 3a and Figure 4 As shown, the film sticking device 400 includes: at least one second film sticking component 500 (i.e. Figure 4, connected to the first driving assembly 300, and configured to move along a first direction (such as Figure 4 The first film-attaching assembly 100 and the second film-attaching assembly 500 move along the second direction (such as Figure 4 The first film assembly 100 is arranged in the Y direction in the second direction, and is located outside the second film assembly 500 in the second direction (that is, the second film assembly 500 is located between at least two first film assemblies 100 in the second direction), and the second direction is arranged to cross the first direction.

[0035] In a specific example, if Figure 4 As shown, two first film-attaching assemblies 100 are connected to both ends of the second support member 310, and at least one second film-attaching assembly 500 is connected to the central area of ​​the second support member 310. The second support member 310 will be described in detail later.

[0036] With this structure, since the first film-mounting assembly 100 has a driving unit 120, the driving unit 120 can drive the film-mounting unit 110 to move. Compared with the second film-mounting assembly 500, the first film-mounting assembly 100 can move a longer distance. Therefore, compared with the second film-mounting assembly 500, the first film-mounting assembly 100 can attach a longer distance of film tape, so that the length of the film tape attached to the edge of the photovoltaic module 200 is longer than the length of the film tape attached to the center, such as Figure 3a and Figure 3b As shown, for the convenience of describing that the A film tape is the film tape attached to the first film assembly 100, and the B film tape is the film tape attached to the second film assembly, the two ends of the A film tape are longer than the B film tape. In this way, when attaching the C film tape in the second direction (such as the Y direction), if the C film tapes of equal length are attached between the A film tapes, the two ends of the C film tape can cover the edge area of ​​the photovoltaic assembly 200 while preventing the two ends of the C film tape from overlapping with the two ends of the A film tape and the B film tape, thereby improving the reliability of the C film tape adhesion and preventing the C film tape from falling off.

[0037] In a specific example, if Figure 3a As shown, taking the film attaching device 400 attaching the left film strip along the X direction as an example, the following method can be used: initially, the first film attaching assembly 100 and the second film attaching assembly 500 are located at the first end (i.e. Figure 3aThe driving component 120 drives the film pasting unit 110 to move in the opposite direction of the X direction (i.e., to the first end of the photovoltaic component 200), so that the film pasting starting point of the first film pasting component 100 is closer to the side of the first end of the photovoltaic component 200 relative to the second film pasting component 500, and then the first driving component 300 drives the first film pasting component 100 and the second film pasting component 500 to move in the X direction. During this process, the driving unit 120 gradually drives the film pasting unit 110 to move in the X direction. When the film pasting stops, the film pasting end points of the first film pasting component 100 and the second film pasting component 500 are the same.

[0038] In some embodiments, Figure 1 and Figure 2 As shown, the driving unit 120 includes: a first guide rail 121, connected to the first support member 130 and extending along the first direction; a first slider 122, slidably connected to the first guide rail 121 and connected to the film-laminating unit 110; a first driving source 123, connected to the first support member 130 and to the first slider 122, and configured to drive the first slider 122 to slide along the first guide rail 121, so that the first slider 122 drives the film-laminating unit 110 to move along the first direction.

[0039] Specifically, the first driving source 123 may include a cylinder or a motor, the first driving source 123 and the first slider 122 are arranged below the first guide rail 121, and the first driving source 123 has a push rod connected to the first slider 122, and pushes the first slider 122 to slide along the first guide rail 121. This structure is simple, easy to produce, and low in cost.

[0040] In some embodiments, Figure 1 and Figure 4 As shown, the first driving assembly 300 includes: a second support member 310 connected to the first support member 130 of at least one first film-mounting assembly 100; a second driving source 320 connected to the second support member 310 and configured to drive the second support member 310 to move along the first direction.

[0041] Exemplarily, the second support member 310 may include a sliding frame, and the second driving source 320 may include a motor, a second slider and a second guide rail. The second slider is connected to the second support member 310, and the second slider can slide along the second guide rail driven by the motor, thereby driving the second support member 310 to move.

[0042] Through this structure, the second driving source 320 can drive at least one first film attaching assembly 100 to move in the first direction.

[0043] In some embodiments, Figure 2As shown, the driving unit 120 further includes: a horizontally arranged connecting member 127 , a first guide rail 121 connected to the bottom of the connecting member 127 , and a first supporting member 130 connected to the connecting member 127 .

[0044] In some embodiments, Figure 1 and Figure 2 As shown, the driving unit 120 further includes: an angle seat 124 having a first surface and a second surface arranged vertically, the first surface being connected to the first support member 130 , and the second surface being connected to the first guide rail 121 .

[0045] For example, Figure 2 As shown, the first surface of the corner seat 124 extends in the vertical direction and is connected to the first support member 130 , and the second surface of the corner seat 124 extends in the horizontal direction and is connected to the upper surface of the connecting member 127 .

[0046] By providing the angle seat 124 , the first guide rail 121 can be firmly connected to the first support member 130 , thereby preventing the first guide rail 121 from deviating relative to the first support member 130 .

[0047] In some embodiments, Figure 1 and Figure 2 As shown, the film sticking unit 110 has a connecting portion, which has a threaded hole, and the driving unit 120 also includes: a connecting block 125, which is connected to the first slider 122, and the connecting block 125 has a through groove 1251 and a through hole, and the connecting portion is at least partially embedded in the through groove 1251; a screw connection member, which passes through the through hole and is screwed to the threaded hole.

[0048] The connecting portion may be exemplarily a mounting plate 111 described below, and the screw connection may be exemplarily a screw or a bolt. By at least partially embedding the connecting portion into the through slot 1251, the groove wall of the through slot 1251 may limit the connecting portion from rotating, and the connecting block 125 and the film attaching unit 110 may be firmly connected by the screw connection.

[0049] In some embodiments, Figure 1 As shown, the driving unit 120 includes: a stopper 126 connected to the first guide rail 121, and configured to limit the moving distance of the first slider 122 on the first guide rail 121. By setting the stopper 126, the moving distance of the first slider 122 can be accurately limited. Here, the stopper 126 can also be connected to the connecting member 127 above the guide rail 121.

[0050] In some embodiments, the stop block 126 has a vertically arranged vertical plate and a horizontally arranged horizontal plate, the first end of the vertical plate is connected to the connecting member 127, the second end of the vertical plate is connected to the first end of the horizontal plate, the horizontal plate extends in the horizontal direction, and the second end of the horizontal plate is configured to limit the slider 122.

[0051] In some embodiments, Figure 1 As shown, the film sticking unit 110 includes: a mounting plate 111 connected to the driving unit 120; a clamping structure 112 connected to the mounting plate 111 and configured to press the film tape onto the upper surface of the photovoltaic module 200; and a film cutting structure 113 connected to the mounting plate 111 and configured to cut the film tape.

[0052] Specifically, when the first film-sticking component 100 starts to stick the film, the driving unit 120 can first drive the first slider 122 to the first end of the first guide rail 121, and then the pressure wheel in the clamping structure 112 descends to attach the film tape to the starting film-sticking point. Then the first driving component 300 and the driving unit 120 drive the mounting plate 111 to move in the first direction (wherein the driving unit 120 drives the first slider 122 to move toward the second end of the first guide rail 121 to drive the mounting plate 111 to move in the first direction). Since the pressure wheel always presses the film tape, the film tape can be attached to the upper surface of the photovoltaic component 200. When the film tape is attached to the end point, the film cutting structure 113 cuts the film tape.

[0053] By connecting both the pressing structure 112 and the film cutting structure 113 to the mounting plate 111 , the pressing structure 112 and the film cutting structure 113 can be driven to move synchronously when the mounting plate 111 moves, thereby achieving film attachment to the photovoltaic module 200 .

[0058] The second direction is exemplarily a horizontal direction perpendicular to the first direction, such as Figure 3b In the Y direction, the film tape (referred to as C film tape) attached by the film attaching machine 710 can be exemplarily as follows: Figure 3b As shown, the C film strips are of equal length, the A film strip is longer than the B film strip at both ends, and the C film strip does not overlap with the edges of the A film strip and the B film strip, so that the C film strip is more securely adhered.

[0059] In a specific application scenario, the photovoltaic module 200 without film tape attached can be first transported to the string spacing film laminating machine 600 for film laminating, and then the photovoltaic module 200 can be transported to the slice spacing film laminating machine 710 for film laminating.
