Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic module production equipment, and in particular to a gluing device. Background Art

[0002] Photovoltaic modules are the core components of solar power generation systems. Their function is to convert solar energy into electrical energy and store it in batteries through off-grid systems, or connect it to loads or integrate it into the power grid.

[0003] During the production of photovoltaic modules, they undergo a framing process to increase their mechanical strength and sealing performance and protect the glass edges. During the framing process, silicone is first applied to the frame's slots using a gluing device. The frame is then installed on the glass edge of the module and secured with corner brackets. However, during the framing process, the frame often suffers from either insufficient or excessive glue. Lack of glue can result in inadequate sealing of the module's edges, reducing its resistance to wind, dust, and rain, and making it susceptible to oxidation. Excessive glue can cause silicone to overflow from the frame, making the module's surface dirty and difficult to clean, affecting its appearance and power generation performance.

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features.

If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.

[0038] An embodiment of the present application provides a glue-spraying device for injecting colloid into the frame of a photovoltaic module, wherein the frame includes a long frame 51 and a short frame 52. The colloid includes but is not limited to silicone, glue, etc., which are not limited here. Figure 1 as well as Figure 2 The gluing device of one embodiment includes a carrying mechanism, a gluing mechanism 20, a weighing mechanism and an alarm mechanism 30, wherein the carrying mechanism is used to carry the frame of the photovoltaic module. The gluing mechanism 20 is arranged on the carrying mechanism, and the gluing mechanism 20 is used to inject colloid into the frame. The weighing mechanism (not shown) is arranged on the carrying mechanism, and the weighing mechanism is used to obtain the weight of the frame. The alarm mechanism 30 is communicated with the weighing mechanism, and when the weight difference before and after gluing the frame does not fall within a preset range, the alarm mechanism 30 sends an alarm signal. Among them, the preset range value can be pre-stored in the control program of the gluing device and automatically called when the gluing device is working, or it can be manually input into the alarm mechanism 30 by the worker before each gluing, and there is no limitation here.

[0039] The above-mentioned gluing device can obtain the weight of the frame before gluing and the weight of the frame after gluing in real time through the weighing mechanism. The alarm mechanism 30 calculates the weight difference of the frame before and after gluing to obtain the gluing amount of the frame. When the weight difference of the frame before and after gluing does not fall within the preset range, it means that the frame after gluing is short of glue or has too much glue. At this time, the alarm signal is issued, thereby promptly reminding the operator of the gluing abnormality so that the operator can debug the gluing device in time, realizing real-time monitoring of the gluing amount of the frame without stopping the machine, reducing the situation of short of glue or too much glue after gluing the frame, and thus improving the quality of the finished product of the photovoltaic module.

[0040] See also Figure 1 In one embodiment, the support mechanism includes a slide rail (not shown), a support platform 11, and a first drive member (not shown). The support platform 11 is movably coupled to the slide rail and is used to support the frame. The weighing mechanism is disposed on the support platform 11. The first drive member is connected to the support platform 11 and is used to drive the support platform 11 along the slide rail to the gluing station. Specifically, the first drive member can be a dual-axis cylinder.

[0041] Specifically, before work, the long frame 51 and the short frame 52 of the photovoltaic module are first fixed on the supporting platform 11. Then the first driving member drives the supporting platform 11 to move along the slide rail together with the frame to the gluing station. At this time, the weighing mechanism obtains the weight of the frame before gluing, and then the gluing mechanism 20 injects colloid into the frame along the frame. Then the weighing mechanism obtains the weight of the frame after gluing. The alarm mechanism 30 calculates the weight difference of the frame before and after gluing. When the weight difference of the frame before and after gluing falls within the preset range, it means that the gluing is qualified. The first driving member drives the supporting platform 11 to move along the slide rail together with the frame after gluing to the next process. When the weight difference of the frame before and after gluing does not fall within the preset range, it means that the frame after gluing is short of glue or has too much glue. At this time, the alarm signal is issued, the gluing device is shut down, and the staff debugs the gluing device.

[0042] Optionally, in one embodiment, the weighing mechanism includes a pressure sensor (not shown), and the supporting platform 11 includes a first platform (not shown) and a second platform (not shown) stacked together. The first platform is movably coupled to the slide rail, and the second platform is used to support the frame. The pressure sensor is disposed between the first and second platforms. In this manner, by detecting the pressure change on the first platform before and after the frame is glued, the weight change before and after the glue is applied can be determined, thereby determining the amount of glue applied to the frame.

[0043] Optionally, in one embodiment, the gluing device further includes a positioning mechanism 40 , which is disposed on the carrying platform 11 . The positioning mechanism 40 is used to fix the frame to prevent the frame from shifting during the gluing process.

[0044] Specifically, see Figure 3 The positioning mechanism 40 includes an X-direction positioning assembly 41 and a Y-direction positioning assembly 42. The X-direction positioning assembly 41 is disposed on the supporting mechanism and is used to limit the displacement of the frame along the X direction. The Y-direction positioning assembly 42 is disposed on the supporting mechanism and is used to limit the displacement of the frame along the Y direction. The X direction is perpendicular to the Y direction. Specifically, in one embodiment, the X direction is the width direction of the frame, and the Y direction is the length direction of the frame. In this way, the frame is limited in the width direction by the X-direction positioning assembly 41, and the frame is limited in the length direction by the Y-direction positioning assembly 42. This effectively corrects the position of the frame and ensures that the glue mechanism 20 can accurately inject the glue into the card slot of the frame.

[0045] Continue to see Figure 3 In one embodiment, the X-axis positioning assembly 41 includes a second driving member 411 and a clamping member 412 connected to the second driving member 411. The second driving member 411 is used to drive the clamping member 412 to clamp or release the frame. Specifically, the second driving member 411 can be a cylinder, and the clamping member 412 includes two clamping blocks. The second driving member 411 is used to drive the two clamping blocks to move toward or away from each other, thereby clamping or releasing the frame. Furthermore, there are multiple X-axis positioning assemblies 41, and the multiple X-axis positioning assemblies 41 are spaced apart along the length direction of the frame, thereby improving the limiting effect on the frame.

[0046] Continue to see Figure 3 In one embodiment, the Y-direction positioning assembly 42 includes a third driving member 421 and an abutting member 422 connected to the third driving member 421, and the third driving member 421 is used to drive the abutting member 422 to abut or separate from the end of the frame. Specifically, in one embodiment, the carrying platform 11 carries two long frames 51 and two short frames 52. In the Y-direction positioning assembly 42 for positioning the long frames 51, the second driving member 411 is a cylinder and the abutting member 422 is a stopper. Furthermore, a Y-direction positioning assembly 42 is provided at each end of each long frame 51, and the cylinders of the two Y-direction positioning assemblies 42 respectively drive the stoppers to abut the ends of the long frames 51, thereby achieving positioning of the long frames 51 in the length direction. In the Y-direction positioning assembly 42 for positioning the short frames 52, the second driving member 411 can be a track slider mechanism, and the abutting member 422 can be a baffle. The track slider mechanism drives the baffle to abut the ends of the two short frames 52 at the same time, thereby achieving simultaneous positioning of the two short frames 52 in the length direction.

[0047] See also Figure 1Optionally, in one embodiment, the glue-spraying mechanism 20 includes a Y-drive assembly 21, an X-drive assembly 22, a Z-drive assembly 23, and a glue hose 24. The Y-drive assembly 21 is connected to the X-drive assembly 22 to drive the X-drive assembly 22 to move in the Y direction; the X-drive assembly 22 is connected to the Z-drive assembly 23 to drive the Z-drive assembly 23 to move in the X direction; the Z-drive assembly is connected to the glue hose 24 to drive the glue hose 24 to move in the Z direction. The glue hose 24 is used to inject glue into the frame. The Y, X, and Z directions are arranged perpendicular to each other. In this way, the glue hose 24 can be driven to move in three perpendicular directions, ensuring that the glue hose 24 can be aligned with the frame at different positions. In one embodiment, the Y direction is the length direction of the frame, the X direction is the width direction of the frame, and the Z direction is the height direction of the frame.

[0048] Specifically, in one embodiment, the Y-axis drive assembly 21 can be a linear module, which is installed on both sides of the loading platform. The X-axis drive assembly 22 can also be a linear module, which is installed above the loading platform. The Z-axis drive assembly 23 can be a lifting cylinder.

[0049] Furthermore, there are at least two Z-drive assemblies 23, each of which is connected to the X-drive assembly 22. Each Z-drive assembly 23 is connected to a hose 24. For example, in this embodiment, two Z-drive assemblies 23 are provided on the X-drive assembly 22, each of which is connected to a hose 24. This allows gluing of two long frames 51 or two short frames 52 simultaneously, thereby improving production efficiency.

[0050] See also Figure 1 as well as Figure 2 The alarm mechanism 30 includes a display connected to the weighing mechanism. The display is used to display the weight difference between the frame before and after gluing, so that the operator can more intuitively observe the amount of gluing applied to the frame in real time. Furthermore, the alarm information can also be displayed on the display in the form of text or symbols so that the operator can obtain the alarm information more quickly.

[0051] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application.
