DETAILED DESCRIPTION

[0039] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] The laminating chamber of the laminating machine is provided with laminating units, and when the adjacent laminating units are covered, the photovoltaic modules located between the adjacent laminating units can be laminated. The high temperature cloth of the existing laminating units is easy to slip when conveying the modules, which is not conducive to the conveyance of the photovoltaic modules.

[0041] In view of this, the present application provides a lamination conveying unit. Figures 1 to 4 As shown, the lamination conveying unit in the embodiment of the present application includes a driving shaft 1, a driven shaft 2, a high temperature cloth 3 and a supporting component 4, wherein:

[0042] The driving shaft 1 is arranged at the first end of the supporting component 2 , the driven shaft 2 is arranged at the second end of the supporting component 4 , and the high temperature cloth 3 is wound around the driving shaft 1 and the driven shaft 2 and covers the supporting component 4 .

[0043] Active transmission components 5 are disposed at both ends of the active shaft 1 , and meshing structures 6 are disposed at both side edges of the high-temperature cloth 3 , and the meshing structures 6 mesh with the active transmission components 5 .

[0044] In one implementation, the active transmission member may be any one of a gear and a sprocket.

[0045] When the driving shaft 1 rotates, it drives the driving transmission member 5 to rotate synchronously. When the driving transmission member 5 rotates, it drives the high-temperature cloth 3 to rotate through the meshing structure 6 to transmit the photovoltaic components carried on the high-temperature cloth 3.

[0046] It can be seen that in the lamination conveying unit provided by the present application, since active transmission parts 5 are provided at both ends of the active shaft 1, meshing structures 6 cooperating with the active transmission parts 5 are provided on both sides of the high-temperature cloth 3. When the high-temperature cloth 3 is conveyed under the drive of the active shaft 1, the active transmission parts 5 and the meshing structures 6 realize the meshing constraint of the high-temperature cloth 3, thereby avoiding the high-temperature cloth 3 from slipping during the conveying process, and ensuring the accuracy and conveying stability of the high-temperature cloth 3.

[0047] Optionally, both ends of the driven shaft 2 are provided with driven transmission members 11, and the meshing structure 6 of the high temperature cloth 3 is also meshed with the driven transmission member 11. In this way, both ends of the high temperature cloth 3 are meshed with the transmission member, thereby further improving the conveying stability of the high temperature cloth 3.

[0048] In one implementation, the driven transmission member 11 may be any one of a gear and a sprocket.

[0049] like Figure 2 In the illustrated embodiment, the meshing structure 6 includes a plurality of meshing holes equidistantly arranged at the edge of the high temperature cloth 3 along the extension direction of the high temperature cloth 3. The hole spacing of the meshing holes matches the tooth spacing of the active transmission member 5 at the corresponding position. The meshing holes are used as the meshing structure 6, which reduces the complexity of the arrangement and the preparation cost of the meshing structure 6.

[0050] In another embodiment, the meshing structure 6 is a flexible rack arranged at the edge of the high temperature cloth along the extension direction of the high temperature cloth 3. The tooth spacing of the flexible rack matches the tooth spacing of the active transmission member 5 at the corresponding position. The meshing stability between the flexible rack and the active transmission member is higher, and it can be easily replaced, thereby extending the service life of the high temperature cloth 3.

[0051] In order to facilitate the installation of the driving shaft 1 and the driven shaft 2, optionally, the first driving shaft mounting bracket 7 and the second driving shaft mounting bracket 8 are respectively provided on both sides of the first end of the support component 4, and the two ends of the driving shaft 1 are respectively rotatably connected to the first driving shaft mounting bracket 7 and the second driving shaft mounting bracket 8. The first driven shaft mounting bracket 9 and the second driven shaft mounting bracket 10 are respectively provided on both sides of the second end of the support component 4, and the two ends of the driven shaft 2 are respectively rotatably connected to the first driven shaft mounting bracket 9 and the second driven shaft mounting bracket 10.

[0052] In addition, the lamination conveying unit in the embodiment of the present application further includes a driver, which is in driving connection with the driving shaft 1, and is used to drive the driving shaft 1 to rotate. The driver may be, for example, a driving cylinder in driving connection with the driving shaft 1.

[0053] Optionally, a first connecting member is installed on the first driving shaft mounting bracket 7 and the second driving shaft mounting bracket 8, respectively. A second connecting member is installed on the first driven shaft mounting bracket 9 and the second driven shaft mounting bracket 10, respectively. The first connecting member and the second connecting member are hooks, blocks or bolt connection structures. In this way, the four corners of the laminating conveying unit can be installed on the frame of the laminating machine through a connecting member, ensuring the installation stability of the laminating conveying unit and keeping the laminating conveying unit level.

[0054] like Figure 5 As shown, optionally, the supporting component 4 includes at least two heating plates, and the at least two heating plates are arranged along the conveying direction of the high temperature cloth (such as Figure 5 The high temperature cloth sleeve is arranged in the X-axis direction of the lamination, and is set on at least two heating plates. Such an arrangement extends the conveying stroke of the lamination conveying unit of the embodiment of the present application, so that the photovoltaic module passes through at least two lamination stations under the conveyance of the lamination conveying unit, thereby receiving at least two lamination operations.

[0055] In one implementation, a rim is provided at the edge of the high temperature cloth, and the engagement holes are provided on the rim.

[0056] In one implementation, the edge includes a U-shaped metal sheet, which clamps the side of the high temperature cloth in the middle of the U-shaped opening. Of course, the edge can also be made of plastic. The metal sheet is provided with through holes corresponding to the meshing holes on the high temperature cloth.

[0057] The edge strength of the high-temperature cloth is increased by setting the hemming, thereby avoiding damage to the high-temperature cloth caused by applying force to the meshing hole to drive the high-temperature cloth, and extending the service life of the high-temperature cloth.

[0058] In one implementation, a reinforcement ring is provided on the engagement hole.

[0059] The reinforcement ring is a rivet structure and is installed in the meshing hole to protect the high-temperature cloth at the meshing hole and prevent the high-temperature cloth from being torn.

[0060] The strength of the high-temperature cloth meshing hole is further enhanced by the provision of the reinforcing ring, thereby avoiding damage to the high-temperature cloth at the meshing hole caused by applying force to the meshing hole.

[0061] In one implementation, a rim is provided at the edge of the high temperature cloth, an engagement hole is provided on the rim, and a reinforcement ring is provided on the engagement hole on the rim, so as to further enhance the strength of the high temperature cloth.

[0062] A lamination unit is also provided in an embodiment of the present application, which includes the lamination conveying unit and the silicone plate and the heating element provided in any of the above embodiments, wherein the silicone plate is arranged at the bottom of the supporting component of the lamination conveying unit, and the heating element is arranged between the silicone plate and the supporting component, and the heating element is used to heat the supporting component.

[0063] The lamination unit provided in the present application can realize the lamination of photovoltaic components and the transportation of the photovoltaic components located thereon.

[0064] The lower surface of the support component 4 is provided with a coil installation groove, and the heating element is an electromagnetic heating wire installed in the coil installation groove. Alternatively, the heating element is a resistance heating element arranged in the support component 4. Alternatively, the heating element is a channel for hot press oil to flow arranged in the support component 4, and the hot press oil flows in the channel to heat the support component 4.

[0065] Since the support component 4 has heating performance, when the two adjacent laminating units arranged above and below are closed and the photovoltaic module located between them is laminated, the laminating unit below can heat the photovoltaic module, thereby melting the EVA in the heated photovoltaic module. Finally, under the continuous lamination, the melted EVA bonds and solidifies the battery sheet, cover glass and back panel together.

[0066] The embodiment of the present application further provides a laminator, which includes n laminators provided by any of the above embodiments arranged vertically at intervals, and a laminator drive mechanism, wherein the laminator drive mechanism is used to drive the n laminators to rise and fall, so that two adjacent laminators are closed or opened. When two adjacent laminators are closed, the photovoltaic modules located between the two adjacent laminators are laminated.

[0067] The laminator provided in the present application is composed of n lamination units arranged at intervals in the vertical direction. When the n lamination units are closed synchronously, two adjacent lamination units can laminate the photovoltaic modules therebetween, thereby improving the lamination efficiency.
