DETAILED DESCRIPTION

[0025] 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.

[0026] Application Overview

[0027] There are gaps between the strings and cells on the photovoltaic backplane, and the light energy irradiated into these gaps is difficult to be absorbed and utilized. Therefore, reflective film is usually attached to the gaps between the strings and cells in the photovoltaic backplane through a film laminating machine (including a string spacing film laminating machine and a cell spacing film laminating machine). The film laminating machine usually has a conveying device to connect with the production line. For example, the conveying device can be used to convey the photovoltaic backplane in the previous production line to the film laminating device of the film laminating machine for film laminating, can be used to convey the photovoltaic backplane after film laminating by the film laminating device of the film laminating machine to the next production line, and can also be used to convey the photovoltaic backplane after film laminating by the film laminating device of the string spacing film laminating machine to the film laminating device of the cell spacing film laminating machine for film laminating.

[0028] In the related art, the conveyor device is usually arranged outside the frame of the film laminating machine so as to dock with the production line. Since the film tape reel of the film laminating machine needs to be manually changed, the setting position of the conveyor device occupies the working space of manual operation (for example, the conveyor device is arranged outside the frame so that the operator does not have enough standing space), thereby hindering manual reel change.

[0029] In view of this, the present application proposes a conveying device and a film laminating machine, wherein the conveying device is configured to convey a photovoltaic backboard, and the conveying device includes: a frame assembly, having a accommodating space; a conveying assembly, located outside the accommodating space and rotatably connected to the frame assembly, the conveying assembly is configured to convey the photovoltaic backboard; a telescopic drive assembly, the telescopic drive assembly includes a fixed part and a telescopic part, the fixed part is located in the accommodating space and connected to the frame assembly, the first end of the telescopic part is connected to the fixed part, and the second end of the telescopic part is connected to the conveying assembly, the telescopic part can extend or retract in the accommodating space to drive the conveying assembly to unfold or fold.

[0030] Through this structure, the telescopic drive assembly can fold the conveying assembly, thereby reducing the space occupied by the conveying assembly. Moreover, since the fixed part is located in the accommodating space of the frame assembly, the telescopic part can be extended or retracted in the accommodating space, and the conveying assembly is located outside the accommodating space, that is, the telescopic part can move a long distance, so that the conveying assembly can be fully folded, and then the conveying assembly can be against the frame assembly, providing sufficient operating space for manual roll changing.

[0031] Exemplary Devices

[0032] Figure 1 FIG. 1 is a schematic diagram of the structure of a conveying device provided by an exemplary embodiment of the present application. Figure 2 Shown is a schematic structural diagram of a conveying device provided by another exemplary embodiment of the present application.

[0033] like Figure 1 and Figure 2 As shown, the present application provides a conveying device 100, which is configured to convey a photovoltaic backsheet; wherein the conveying device 100 includes: a frame assembly 110, which has a storage space; a conveying assembly 120, which is located outside the storage space and is rotatably connected to the frame assembly 110, and the conveying assembly 120 is configured to convey the photovoltaic backsheet; a telescopic driving assembly 130, the telescopic driving assembly 130 includes a fixed portion 131 and a telescopic portion 132, the fixed portion 131 is located in the storage space and is connected to the frame assembly 110, the first end of the telescopic portion 132 is connected to the fixed portion 131, and the second end of the telescopic portion 132 is connected to the conveying assembly 120, and the telescopic portion 132 can be extended or retracted in the storage space to drive the conveying assembly 120 to expand (such as Figure 1 as shown) or folded (as Figure 2 shown).

[0034] In some embodiments, the photovoltaic backplane may be a glass backplane or a soft backplane, etc.

[0035] In some embodiments, the telescopic drive assembly 130 may be a cylinder or a hydraulic cylinder. Taking the telescopic drive assembly 130 as a cylinder as an example, the fixed portion 131 includes a cylinder barrel, and the telescopic portion 132 includes a piston rod.

[0036] In some embodiments, the telescopic portion 132 can drive the conveying assembly 120 to rotate 90 degrees or more. For example, the telescopic portion 132 can drive the conveying assembly 120 from a horizontal state (i.e., an unfolded state, such as Figure 1 As shown) rotated to a vertical state (i.e., a folded state, as shown Figure 2 ), and rotate from a vertical state to a horizontal state.

[0037] Through this structure, since the telescopic drive assembly 130 can fold the conveying assembly 120, the space occupied by the conveying assembly 120 is reduced, and since the fixed part 131 is located in the accommodating space of the frame assembly 110, the telescopic part 132 can be extended or retracted in the accommodating space, and the conveying group 120 is located outside the accommodating space, that is, the moving stroke of the telescopic part 132 can be longer, so that the conveying assembly 120 can be fully folded, and then the conveying assembly 120 can be against the frame assembly 110 (specifically, it can be against the support plate 111, the support plate 111 will be described in detail later), providing sufficient operating space for manual roll changing.

[0038] For example, if the support plate 111 is vertically arranged, the conveying assembly 120 can be rotated from a horizontal direction to a vertical direction abutting the support plate 111, that is, the conveying assembly 120 is rotated 90 degrees; if the support plate 111 is tilted toward the accommodating space, the conveying assembly 120 can be rotated more than 90 degrees when it is rotated from a horizontal direction to a direction abutting the support plate 111.

[0039] Figure 3 Shown is a right side view of a conveying device provided by an exemplary embodiment of the present application. Figure 4 Shown is a left side view of a conveying device provided by an exemplary embodiment of the present application.

[0040] In some embodiments, the telescopic drive assembly 130 further includes: a first hinge 133, a first end of the first hinge 133 is connected to the frame assembly 110, and a second end of the first hinge 133 is connected to the fixing portion 131; a second hinge 134, a first end of the second hinge 134 is connected to the telescopic portion 132, and a second end of the second hinge 134 is connected to the conveying assembly 120. Through this structure, the two ends of the telescopic drive assembly 130 can be rotatably connected to the frame assembly 110 and the conveying assembly 120, respectively, so that the telescopic drive assembly 130 can move flexibly to drive the conveying assembly 120 to rotate.

[0041] In some embodiments, the first end of the conveying assembly 120 is rotatably connected to the frame assembly 110; wherein the second end of the telescopic portion 132 is hinged to the second end of the conveying assembly 120, and the photovoltaic backsheet is transported from the first end of the conveying assembly 120 to the second end of the conveying assembly 120; or, the second end of the telescopic portion 132 is hinged to the middle area of ​​the conveying assembly 120. Since the force is inversely proportional to the magnitude of the lever arm under the same torque, the farther the connection between the second end of the telescopic portion 132 and the conveying assembly 120 is from the first end of the conveying assembly 120, the smaller the force required to flip the conveying assembly 120. Therefore, if the second end of the telescopic portion 132 is hinged to the second end of the conveying assembly 120, the driving force of the telescopic portion 132 can be reduced, saving energy consumption. If the second end of the telescopic portion 132 is hinged to the middle area of ​​the conveying assembly 120, a telescopic portion 132 with a shorter length can be selected to save costs.

[0042] In some embodiments, Figure 1 , Figure 2 and Figure 3As shown, the frame assembly 110 includes: a frame 112, in which a storage space is formed; a support plate 111, which is vertically arranged and connected to the frame 112, and the support plate 111 has a through hole 1111, and the through hole 1111 is connected to the storage space; wherein the first end of the conveying assembly 120 is rotatably connected to the upper end of the support plate 111; wherein the first end of the fixed portion 131 is hinged to the frame 112, and the second end of the telescopic portion 132 is hinged to the conveying assembly 120 through the through hole 1111. The frame 112 is exemplarily made of square steel. By setting the support plate 111, the rotation angle of the conveying assembly 120 can be limited. For example, when the conveying assembly 120 is Figure 1 The posture rotates to Figure 2 When in the posture, the support plate 111 can limit the further rotation of the conveying assembly 120, and through this structure, the telescopic part 132 can extend from the accommodating space through the through hole 1111 and be hinged to the conveying assembly 120, so that the telescopic part 132 can move a longer distance to drive the conveying assembly 120 to rotate.

[0043] Figure 5 An exemplary embodiment of the present application is shown. Figure 2 A partial enlarged view of area A in FIG.

[0044] In some embodiments, Figure 1 and Figure 5 As shown, the conveying assembly 120 includes: a bracket 124, connected to the second end of the telescopic portion 132; a driving member 125, mounted on the bracket 124; a driving wheel 121, rotatably connected to the first end of the bracket 124, and transmission-connected to the driving member 125, and configured to rotate under the drive of the driving member 125; a driven wheel 129, rotatably connected to the second end of the bracket 124; a conveyor belt 127, sleeved on the driving wheel 121 and the driven wheel 129, configured to carry at least part of the photovoltaic backsheet, and rotate under the drive of the driving wheel 121, and drive the driven wheel 129 to rotate. Among them, the driving member 125 exemplarily includes a motor. Through this structure, the conveying assembly 120 can stably transport the photovoltaic backsheet.

[0045] In some embodiments, Figure 1 , Figure 2 and Figure 5As shown, the conveying assembly 120 also includes: a rotating shaft 122, which is installed on the frame 112 and is rotatably connected to the bracket 124. The rotating shaft 122 passes through the driving wheel 121 and is configured to enable the driving wheel 121 to rotate relative to the rotating shaft 122, and to enable the bracket 124 to rotate around the rotating shaft 122. That is, when the conveying assembly 120 is started, the driving wheel 121 can rotate relative to the rotating shaft 122. When the telescopic part 132 drives the bracket 124 to rotate, the bracket 124 can also rotate around the rotating shaft 122. There is no need to separately set two rotating shafts to enable the driving wheel 121 and the bracket 124 to rotate around them respectively, saving cost and space.

[0046] In some embodiments, Figure 1 and Figure 5 As shown, the frame assembly 110 further includes: a bearing seat 113 connected to the frame 112 , and the rotating shaft 112 passes through the bearing seat 113 and is rotatably connected to the bearing seat 113 .

[0047] In some embodiments, Figure 5 As shown, the frame assembly 110 further includes: a bearing seat connecting plate, the bearing seat connecting plate is connected to the frame 112, and the bearing seat 113 is mounted on the bearing seat connecting plate. Among them, the bearing seat connecting plate can be exemplarily the same component as the abutment 126 (the abutment 126 is described later), or other components.

[0050] In some embodiments, Figure 5As shown, the conveying assembly 120 also includes: a limiting structure 123, which is located on the side of the rotating shaft 122 away from the driven wheel 129 and is installed on the first end of the bracket 124; an abutment 126, which is installed on the frame 112 and is located on the movement track of the limiting structure 123, and the abutment 126 is used to abut against the movement range of the limiting structure 123. By setting the abutment 126, the rotation angle of the bracket 124 can be limited to prevent the bracket 124 from rotating excessively. For example, when the conveying assembly 120 rotates to Figure 1 In the unfolded state (eg, horizontal state) shown, the limiting structure 123 abuts against the abutment member 126 .

[0051] In some embodiments, Figure 5 As shown, the limiting structure 123 includes: a mounting plate 1232, which is located on the side of the rotating shaft 122 away from the driven wheel 129 and is installed on the first end of the bracket 124; a stop bolt 1231, which includes a head and a screw portion fixedly connected to each other, the screw portion is screwed to the mounting plate 1232, and the head of the stop bolt 1231 is used to abut against the abutment 126. Exemplarily, the mounting plate 1232 has a first mounting hole, and the screw portion of the stop bolt 1231 can be screwed to the threaded portion of the first mounting hole. Through this structure, the stop bolt 1231 can be firmly connected, so that the stop bolt 1231 abuts against the abutment 126 to limit the further rotation of the bracket 124.

[0052] In some embodiments, Figure 1 As shown, the bracket 124 includes: a main body 1241; a first connecting plate 1242, connected to the first end of the main body 1241, a first connecting plate 1242 is respectively arranged on both sides of each driving wheel 121, the first connecting plate 1242 has a second mounting hole, the rotating shaft 122 passes through the second mounting hole, and each mounting plate 1232 can be connected to the first connecting plate 1242 on both sides of a driving wheel 121; a second connecting plate 1243, connected to the second end of the main body 1241, a second connecting plate 1243 is respectively arranged on both sides of each driven wheel 129, the second connecting plate 1243 has a third mounting hole; a driven wheel shaft 1244 passes through the third mounting hole, and the driven wheel 129 is sleeved on the driven wheel shaft 1244.

[0054] Specifically, when the photovoltaic backboard is placed on the conveying assembly 120, the photovoltaic backboard is jointly carried by the conveyor belt 127 and the auxiliary roller 128. The auxiliary roller 128 can rotate with the movement of the photovoltaic backboard. By setting the auxiliary roller 128, the range of the conveying assembly 120 that carries the photovoltaic backboard can be increased, so that larger or more photovoltaic backboards can be carried.

[0055] In some embodiments, the conveying assembly 120 further includes: an auxiliary roller shaft connected to the bracket 124, and the auxiliary roller 128 is sleeved on the auxiliary roller shaft.

[0056] In some embodiments, Figure 3 and Figure 4 As shown, the conveying assembly 120 is symmetrically arranged, and the number of the telescopic drive assembly 130 is multiple groups, and the multiple groups of telescopic drive assemblies 130 are symmetrically arranged relative to the vertical symmetry plane of the conveying assembly 120. By symmetrically arranging the multiple groups of telescopic drive assemblies 130, the conveying assembly 120 can be supported and driven to rotate more smoothly. For example, Figure 3 As shown, the two sets of telescopic driving components 130 pass through the through holes 1111 on the left and right sides of the support plate 111 respectively and are connected to the conveying component 120 .

[0057] Based on the same concept, the embodiment of the present application also provides a film laminating machine 200.
