Description

Technical Field

[0001] This utility model relates to the field of photovoltaic processing equipment technology, and in particular to a photovoltaic glass centering and alignment mechanism. Background Technology

[0002] In the production of photovoltaic modules, some processes have high requirements for module positioning. Alignment mechanisms with low accuracy can affect the processing technology and cause defects and rework. For example, in the butyl sealant coating process, traditional alignment usually uses single-sided alignment. When the glass material has a large error, such as ±1mm, single-sided alignment will reflect this 1mm error on the other side, causing the sealant coating error to exceed ±1mm.

[0003] Based on this, the present invention proposes a photovoltaic glass centering and alignment mechanism to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a photovoltaic glass centering and alignment mechanism to achieve centering and alignment of photovoltaic glass and reduce the impact of incoming material errors on production.

[0006] The two alignment wheel brackets are arranged opposite each other, and multiple alignment wheels are installed on the two alignment wheel brackets at intervals. Both alignment wheel brackets are connected to the gear and rack synchronization mechanism.

[0008] Furthermore, the gear and rack synchronization mechanism includes a transmission gear and a transmission rack;

[0009] There are two transmission racks, both of which mesh with the transmission gear, and the two transmission racks are respectively connected to the two centering wheel brackets;

[0011] Furthermore, the gear and rack synchronization mechanism also includes a drive motor;

[0012] The output shaft of the drive motor is connected to the central shaft of the transmission gear, providing driving force for the rotation of the transmission gear.

[0023] The photovoltaic glass centering and alignment mechanism of this utility model will be described in more detail below with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving the advantageous effects of this utility model. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit this utility model.

[0024] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0025] like Figure 1 As shown, this is a photovoltaic glass centering and alignment mechanism in the prior art. It uses four servo motors a to drive the alignment wheel to move. One side uses a hard alignment wheel b, and the other side uses a spring alignment wheel c. When the photovoltaic glass d arrives, the parameters of the four servo motors a need to be adjusted for alignment, which is cumbersome to operate.

[0026] Meanwhile, one side uses spring-loaded alignment and the other side uses hard alignment, which can only guarantee accurate alignment on one side, while the alignment on the other side will be affected by the error of incoming materials.

[0027] like Figure 2 As shown in the figure, this utility model embodiment proposes a photovoltaic glass centering and straightening mechanism, including two straightening wheel supports 1 and a gear and rack synchronization mechanism 2.

[0028] In this embodiment, the two alignment wheel brackets 1 are arranged opposite to each other, and multiple alignment wheels 3 are installed on the two alignment wheel brackets 1 at equal intervals. Both alignment wheel brackets 1 are connected to the gear and rack synchronization mechanism 2. When the gear and rack synchronization mechanism 2 is driven, the two alignment wheel brackets 1 move closer or further apart synchronously.

[0029] Specifically, the gear and rack synchronization mechanism 2 includes a transmission gear 21 and a transmission rack 22; there are two transmission racks 22, both of which mesh with the transmission gear 21, and the two transmission racks 22 are respectively connected to the two alignment wheel brackets 1.

[0030] When the transmission gear 21 rotates, the two transmission racks 22 move the same distance in opposite directions. During the alignment of incoming photovoltaic glass, the transmission gear 21 rotates, causing the two transmission racks 22 to move the alignment wheels 3 on both sides inward by the same distance and contact the side of the photovoltaic glass, thus completing the centering alignment of the photovoltaic glass. Centering alignment distributes the incoming material error evenly to both sides, reducing the impact of incoming material error.

[0031] In the above embodiment, the gear and rack synchronization mechanism 2 further includes a drive motor 23; the output shaft of the drive motor 23 is connected to the central shaft of the transmission gear 21 to provide driving force for the rotation of the transmission gear 21.

[0032] Furthermore, the drive motor 23 is a servo motor, which enables precise programmed control of the photovoltaic glass centering and alignment process.

[0033] In the above embodiments, in conjunction with reference to Figure 3 The aligning wheel 3 is rotatably mounted on the aligning wheel bracket 1 via a rotating bearing 5.

[0034] Specifically, the rotating bearing 5 is mounted on the aligning wheel bracket 1 via a bearing seat, and a mounting stud 4 is fixed in the middle of the rotating bearing 5. The aligning wheel 3 is detachably mounted on the mounting stud 4 via a nut 6.

[0035] By setting the rotating bearing 5, the smoothness of the rotation process of the aligning wheel 3 is improved. The aligning wheel 3 is installed by using the mounting stud 4 and nut 6, which facilitates the maintenance and replacement of the aligning wheel 3.

[0036] Furthermore, the centering wheel 3 is covered with an elastic rubber layer 31 to reduce the risk of damage to the photovoltaic glass caused by hard contact between the centering wheel 3 and the photovoltaic glass during centering.

[0037] In summary, the photovoltaic glass centering and alignment mechanism provided by this utility model has at least the following advantages compared to the prior art:

[0038] The photovoltaic glass centering and straightening mechanism provided by this utility model drives two straightening wheel brackets with straightening wheels to move synchronously through a gear and rack synchronization mechanism, which can realize the centering and straightening of photovoltaic glass. Compared with the single-sided straightening in the prior art, it effectively reduces the impact of incoming material errors on production.

[0039] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
