[0027] The preferred embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the accompanying drawings to illustrate the principles of the present invention.

[0028] Example 1

[0029] This embodiment provides a multi-blade head assembly for photovoltaic module edge cutting. Figures 1 to 2 , including multiple cutter heads, each cutter head includes a cutter 1 and a pad 2, the cutter 1 is placed on the pad 2, and the side of the pad 2 on which the cutter 1 is installed is defined as the mounting surface, and the inclination angle of the mounting surface of the pad 2 relative to the side of the photovoltaic module is adjustable. Among the multiple cutter heads, the inclination angles of the mounting surface of the pad 2 relative to the side of the photovoltaic module are not exactly the same, so that the cutting angles of the cutter 1 are not exactly the same.

[0030] For example, the mounting surface of the backing plate 2 has an inclination angle of 0 to 90 degrees relative to the side of the photovoltaic module. ， For example, 30~60°.

[0031] Compared with the prior art, the multi-blade head assembly for photovoltaic module edge chamfering provided in this embodiment adopts a multi-blade head structure, and the cutting angles of the tools 1 in the multiple blade heads are not exactly the same. During the chamfering process, multiple angles are used in combination to perform multiple chamfering processes on the photovoltaic modules, thereby improving the chamfering action, extending the service life of the tool 1, improving the chamfering quality, and ensuring that no solid glue remains on the photovoltaic modules after chamfering.

[0032] At the same time, since the inclination angle of the installation surface of the pad 2 relative to the side of the photovoltaic module is adjustable, and the inclination angles of the installation surfaces of multiple pads 2 relative to the side of the photovoltaic module are different, in actual applications, the cutting angle of the tool 1 can be adjusted as needed. The operation is simple and convenient, and can effectively reduce the explosion rate of the photovoltaic module.

[0033] Exemplarily, the type of the tool 1 is at least one of a single-sided tool, a double-sided tool, or a U-shaped tool.

[0034] To further improve the quality of edge trimming, the types of cutters 1 in the multiple cutter heads are not identical. Specifically, the cutters 1 may be at least two of the following: single-sided cutters, double-sided cutters, or U-shaped cutters. It should be noted that in actual applications, the types of cutters 1 can be arbitrarily selected and combined. In this way, by combining different types of cutters 1 into the same multi-cutter head assembly, the advantages of each type of cutter 1 can be utilized, further improving the quality of edge trimming and perfecting the edge trimming action.

[0035] Combine Figures 1 to 2 The multi-head assembly for photovoltaic module edge trimming in this embodiment includes two heads, which are the first head and the second head in the trimming direction, and can perform two trimming processes on the photovoltaic module. The tool 1 of the first head and the tool 1 of the second head are both double-sided tools. The inclination angle of the pad 2 of the first head is 45°, and the inclination angle of the pad 2 of the second head is 60°.

[0036] In order to be able to form a whole structure of multiple cutting heads, the above-mentioned multi-cutting head assembly for photovoltaic module edge chamfering also includes a fixed plate 4, and the above-mentioned cutting head also includes a tool holder 3, and the pad 2 is detachably fixedly connected to the fixed plate 4 through the tool holder 3, that is, one side of the tool holder 3 is detachably fixedly connected to the pad 2, and the other side of the tool holder 3 is fixedly connected to the fixed plate 4, and multiple cutting heads share one fixed plate 4.

[0037] Regarding the detachable fixed connection, for example, the multi-tool head assembly for photovoltaic module edge trimming further includes a washer 5 and a screw 6. The tool 1, backing plate 2, tool holder 3, and fixed plate 4 all have mounting holes. The screw 6 passes through the washer 5, tool 1, backing plate 2, tool holder 3, and fixed plate 4 in sequence, completing the detachable fixed connection. It should be noted that through-holes are provided in the tool 1, backing plate 2, and tool holder 3, and a threaded blind hole is provided in the fixed plate 4, through which the screw 6 is threadedly connected.

[0038] It should be noted that there are multiple mounting holes on the fixing plate 4, and the screw 6 passes through one of the mounting holes on the fixing plate 4. In this way, by changing the position of the screw 6 on the fixing plate 4, the relative position of the tool 1 and the fixing plate 4 can be adjusted, and then the actual chamfering surface of the tool 1 can be adjusted to ensure that the tool 1 is fully used and the service life of the tool 1 is extended.

[0039] Considering the problem of insufficient connection stability when connected solely by screws 6, the contact surface between the fixing plate 4 and the tool holder 3 is partially or entirely horizontally stepped. For example, the surface of the fixing plate 4 facing the tool holder 3 is provided with a horizontally extending stepped surface, and the surface of the tool holder 3 facing the fixing plate 4 is provided with a horizontally extending stepped protrusion 7 that cooperates with the stepped surface. The stepped protrusion 7 is placed on the stepped surface to form a horizontally extending stepped contact surface. In this way, through the horizontally extending stepped contact surface, the stepped surface can support the stepped protrusion 7, bearing part of the weight of the tool holder 3, reducing the load-bearing capacity of the screws 6, and thereby improving the stability of the connection between the fixing plate 4 and the tool holder 3.

[0040] The inclination angle of the mounting surface of the backing plate 2 relative to the side surface of the photovoltaic module can be adjusted. For example, the following two methods are used:

[0041] In one embodiment, each cutter head is equipped with a plurality of pads 2, the cutter 1 is detachably fixedly connected to one of the pads 2, and the remaining pads 2 are spare pads.

[0042] Another type, the pad 2 includes a support rod 201, a rotating shaft 202 and a plate body 203, see Figure 3 The rotating shaft 202 is arranged on the side of the plate body 203, one end of the support rod 201 is fixedly connected to the tool holder 3, and the other end of the support rod 201 is rotatably fixedly connected to the rotating shaft 202. The tool 1 is placed on the plate body 203. By rotating the rotating shaft 202, the inclination angle of the installation surface of the plate body 203 relative to the side of the photovoltaic module is adjusted.

[0043] In order to ensure that the tool 1 fits better with the photovoltaic module, the above-mentioned multi-blade head assembly for chamfering the photovoltaic module also includes a telescopic drive member 8 (for example, a cylinder), and the fixed plate 4 is fixedly connected to the output end of the telescopic drive member 8. The telescopic drive member 8 drives the fixed plate 4 to approach or move away from the photovoltaic module, and then drives the tool 1 to approach or move away from the photovoltaic module, ensuring that the tool 1 fits better with the photovoltaic module.

[0044] Example 2

[0045] This embodiment provides a photovoltaic edge trimming machine, including the multi-blade head assembly for photovoltaic module edge trimming provided in the first embodiment.

[0046] Compared with the prior art, the beneficial effects of the photovoltaic edge trimming machine provided in this embodiment are substantially the same as the beneficial effects of the multi-blade head assembly for photovoltaic module edge trimming provided in Example 1, and are not described in detail here.

[0047] It is understood that in order to be able to perform edge chamfering on multiple sides of the photovoltaic module, the number of the multi-blade head assemblies is multiple, for example, 8, and the multiple multi-blade head assemblies are divided into four groups to perform edge chamfering on the four sides of the photovoltaic module respectively. Figure 4 .

[0048] The above description is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
