Description

Technical Field

[0001] The present application relates to the field of photovoltaic module production equipment, and in particular to a photovoltaic module secondary edge trimming device and an edge trimming machine. Background Art

[0002] At present, in the production process of photovoltaic modules, glue will overflow from the laminated parts after the pressing process to form glue strips, so a trimming process is added after the pressing process to remove the glue strips.

[0003] In the related art, after the laminate moves to the trimming station, the trimming machine at the trimming station is started to remove the rubber strips on the edges of the laminate by scraping down. However, sometimes there are still rubber strips remaining at the corners of the laminate. At this time, a secondary trimming device is required. When the secondary trimming device is working, two driving parts, such as cylinders, respectively realize the lifting and lateral movement of the mounting frame, and the other two cylinders respectively realize the approach or separation of the two tools of the tool assembly on the mounting frame, and another cylinder drives the tool assembly to move laterally to achieve trimming.

[0004] However, the inventors realized that in actual operation, the overall structure of the secondary edge trimming device is complex, and it requires too many driving parts to realize the edge trimming work of the secondary edge trimming device. Not only is the production and maintenance cost high, but also when the secondary edge trimming device is working, the movement of too many driving parts will lead to low edge trimming efficiency. Summary of the invention

[0005] One or more embodiments of the present application provide a photovoltaic module secondary edge chamfering device and an edge chamfering machine to solve or at least partially alleviate the problems of high production and maintenance costs and low edge chamfering efficiency of secondary edge chamfering devices in related technologies.

[0006] In a first aspect of the present application, a photovoltaic module secondary edge trimming device is provided, which adopts the following technical solution:

[0007] A secondary edge trimming device for a photovoltaic module comprises a mounting frame, a support frame, a first driving member, a second driving member, a first edge trimming knife and a second edge trimming knife; the support frame is slidably arranged on the mounting frame along a first direction, and is inclined in the first direction, and the first driving member is used to drive the support frame to move along the first direction; the first edge trimming knife and the second edge trimming knife are movably arranged on the support frame, and the second driving member is used to drive the first edge trimming knife and the second edge trimming knife to move closer to or separate from each other.

[0008] By adopting the above technical scheme, after the laminate of the photovoltaic module flows to the secondary trimming station, the first driving member is started, and the first driving member can drive the support frame to move relative to the mounting frame along the first direction. Due to the inclined setting of the first direction, the support frame can move obliquely upward, thereby realizing the displacement of the support frame in two directions. During this process, the vertical and horizontal positions of the support frame can be changed. Since the first trimming knife and the second trimming knife can move together with the support frame, the vertical and horizontal positions of the first trimming knife and the second trimming knife can also be changed until they reach the cutting position. Then the second driving member is started, and the second driving member can drive the first trimming knife and the second trimming knife to move closer to each other until the bottom of the first trimming knife and the second trimming knife contact the laminate of the photovoltaic module. The first driving member is started again, and the first driving member can drive the support frame to move obliquely downward relative to the mounting frame. During this process, the first trimming knife and the second trimming knife can cut the residual rubber strips at the corners of the laminate. In summary, compared with the existing photovoltaic module secondary edge chamfering device, the photovoltaic module secondary edge chamfering device of the present application can effectively reduce the number of driving parts without affecting the normal edge chamfering work, which not only reduces the production and maintenance costs, but also effectively improves the edge chamfering efficiency.

[0035] One or more embodiments of the present application disclose a photovoltaic module secondary edge trimming device.

The first driving member 300 is used to drive the support frame 200 to move along the first direction; the first edge trimming knife 500 and the second edge trimming knife 600 are movably arranged on the support frame 200, and the second driving member 400 is used to drive the first edge trimming knife 500 and the second edge trimming knife 600 to move closer to or separate from each other.

[0036] By adopting the above technical solution, after the laminate of the photovoltaic module flows to the secondary trimming station, the first driving member 300 is started, and the first driving member 300 can drive the support frame 200 to move relative to the mounting frame 100 along the first direction. Since the first direction is inclined, the support frame 200 can move obliquely upward, thereby realizing the displacement of the support frame 200 in two directions. During this process, the position of the support frame 200 in the vertical and horizontal directions can be changed. Since the first trimming knife 500 and the second trimming knife 600 can move with the support frame 200, the first trimming knife 500 and the second trimming knife 600 can move together with the support frame 200. The vertical and horizontal positions of the edge cutter 600 can also be changed until it reaches the cutting position, and then the second driving member 400 is started, and the second driving member 400 can drive the first edge cutter 500 and the second edge cutter 600 to move closer to each other until the bottoms of the first edge cutter 500 and the second edge cutter 600 contact the laminate of the photovoltaic module, and the first driving member 300 is started again, and the first driving member 300 can drive the support frame 200 to move obliquely downward relative to the mounting frame 100. During this process, the first edge cutter 500 and the second edge cutter 600 can cut the residual rubber strips at the corners of the laminate. In summary, compared with the existing photovoltaic module secondary edge cutter, the photovoltaic module secondary edge cutter of this embodiment can effectively reduce the number of driving members without affecting the normal edge cutter work, which not only reduces the production and maintenance costs, but also effectively improves the edge cutter efficiency.

[0037] At the same time, when the photovoltaic module secondary edge trimming device is not working, it is located entirely below the laminate, so it will not interfere with the flow of the laminate.
