Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, and in particular to a testing device. Background Technology

[0002] Currently, the photovoltaic industry is developing rapidly, and the quality of photovoltaic modules directly affects their power generation efficiency and lifespan. In the actual production process of photovoltaic modules, the depth of the sealant application (i.e., the amount of sealant) on the frame directly affects the sealing and durability of the photovoltaic module. The sealant is used to seal the frame and the cell module, achieving waterproofing, weather resistance, insulation, and corrosion resistance, thereby extending the lifespan of the photovoltaic module. To detect the sealant application depth on the frame, the existing technology uses a feeler gauge inserted into the sealant groove (i.e., the A-side sealant groove) of the frame to measure the depth of sealant within the groove. Therefore, the existing detection method is not only time-consuming but also prone to errors, affecting the consistency and reliability of the product. Utility Model Content

After the photovoltaic modules are detected, the drive mechanism drives the detection component to move out of the glue-applying tank and reset.

Detailed Implementation

[0025] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0026] During the photovoltaic module framing process, adhesive is first applied to the adhesive grooves on the four frame sides. Then, the four adhesive-coated frame sides are installed on the four edges of the cell module, forming a ring structure that wraps around the entire edge of the cell module (which consists of sequentially pressed glass, adhesive film, cells, adhesive film, and a backsheet or glass). After framing, to ensure the sealing and durability of the photovoltaic modules, a portion of the modules are randomly selected, and the adhesive depth is checked by manually inserting a feeler gauge into the adhesive grooves on the frame sides. Therefore, the existing testing methods have at least the following problems: 1. Sampling inspection cannot achieve 100% compliance; 2. Sampling inspection cannot detect and report problems immediately, leading to batch anomalies; 3. Manual sampling inspection is time-consuming and labor-intensive, reducing production efficiency and impacting capacity; 4. Measurement with a feeler gauge is not only inefficient but also prone to errors, resulting in low accuracy of the test data and affecting product consistency and reliability.

[0027] It should be noted that photovoltaic modules are always in an upside-down state during production and transportation, that is, the light-receiving side of the photovoltaic module is facing down, and the A side of the frame is facing down.

[0028] Based on this, the detection device 10 of the following embodiments of this application is designed and proposed to solve the above-mentioned technical problems.

[0029] like Figure 1 and Figure 2 As shown, in one embodiment, a testing device 10 is provided for photovoltaic module production. The photovoltaic module includes a frame with a glue-applying groove and a cell module located at the glue-applying groove. The testing device 10 includes a testing element 100 and a driving mechanism 200. The testing element 100 is used to extend into the glue-applying groove to detect the glue-applying depth within the groove. The driving mechanism 200 is drively connected to the testing element 100 and is configured to drive the testing element 100 to extend into or move out of the glue-applying groove when the photovoltaic module moves to the testing station.

[0030] In the detection setup described above, a detection station is set up along the production and conveying path of the photovoltaic modules. The detection device 10 is then installed below the detection station, and the detection component 100 is communicatively connected to the MES system of the production line. When the photovoltaic modules are conveyed to the detection station, the drive mechanism 200 drives the detection component 100 to extend into the glue-applying tank along a preset route to measure the glue-applying depth and humidity in the tank in real time. The data is then transmitted to the MES system for real-time monitoring and data analysis to ensure high measurement accuracy under different environmental conditions. After the photovoltaic modules are detected, the drive mechanism 200 drives the detection component 100 to move out of the glue-applying tank and reset. The photovoltaic modules continue to be conveyed to the next process, and the detection device 10 can continue to detect the next photovoltaic modules conveyed to the detection station. Compared with existing detection methods, the detection device 10 in this application has at least the following advantages: 1. During the photovoltaic module production process, the detection device 10 can detect all photovoltaic modules and perform real-time dynamic monitoring and data analysis, enabling immediate detection of abnormalities, avoiding batch anomalies, and improving the consistency and reliability of photovoltaic modules. 2. The detection component 100 is driven by the drive mechanism 200, reducing manual intervention and improving the efficiency and accuracy of frame adhesive depth detection, thereby increasing the production efficiency and capacity of photovoltaic modules.

[0031] It should be noted that when the photovoltaic module is transported to the testing station in a horizontal direction, and the drive mechanism 200 is ready to drive the testing component 100 to extend into the glue application tank, the testing component 100 is located inside the annular structure.

[0032] The detection element 100 can be any existing detection structure capable of detecting the glue application depth on the frame. For example, the detection element 100 can be a detection probe or a detection rod. Specifically, in this embodiment, the detection element 100 adopts a high-precision sensor structure, which has high sensitivity and anti-interference capability.

[0033] like Figure 1 and Figure 2 As shown, optionally, the driving mechanism 200 includes a first driving member 210 and a second driving member 220, which are driven to and transmitted through the detection member 100. The first driving member 210 drives the detection member 100 to reciprocate along a first direction, and the second driving member 220 drives the first driving member 210 and the detection member 100 to reciprocate along a second direction, with the first and second directions forming an angle. Thus, when the photovoltaic module is transported to the testing station, the second driving member 220 drives the first driving member 210 and the detection member 100 to move simultaneously along a direction closer to the photovoltaic module until the detection member 100 and the glue application tank are on the same plane and then stop. Then, the first driving member 210 drives the detection member 100 to move along a direction closer to the frame, causing the detection member 100 to extend into the glue application tank to measure the glue application depth and moisture content in the tank in real time. After the detection member 100 completes its testing, the first driving member 210 and the second driving member 220 cooperate to drive the detection member 100 back to its original position for the next photovoltaic module to be transported and tested. In addition, the detection component 100 is driven by the first driving component 210 and the second driving component 220, which can effectively adjust the movement trajectory and initial position of the detection component 100, enhance the flexibility of the detection device 10, and improve the accuracy and convenience of the detection process.

[0034] Both the first driving component 210 and the second driving component 220 can be configured as an electric telescopic rod, a telescopic cylinder, a telescopic hydraulic cylinder, or other driving structures. Specifically, in this embodiment, both the first driving component 210 and the second driving component 220 are configured as electric telescopic rods, which are made of high-strength materials. The electric telescopic rods enable smooth telescopic movement, ensuring that the detection component 100 can accurately extend into the adhesive groove of the photovoltaic module's frame.

[0035] The angle between the first direction and the second direction can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, when the photovoltaic module is horizontally transported to the testing station, the second direction is set to the vertical direction, and the first direction is set to be perpendicular to the vertical direction and can correspond to the direction of insertion and removal from the glue application groove.

[0036] like Figure 1 and Figure 2As shown, in one embodiment, the number of detection elements 100 and the number of driving mechanisms 200 are both at least one. Each driving mechanism 200 is spaced apart along the four edges of the detection station, and each detection element 100 is correspondingly arranged with each driving mechanism 200, so that each detection element 100 and each driving mechanism 200 cooperate to form a ring detection structure. In this way, multiple detection elements 100 can simultaneously detect the frame on different sides under the drive of the corresponding driving mechanism 200, improving the detection efficiency of the detection device 10.

[0037] Specifically, in this embodiment, each of the four edges of the inspection station is provided with at least one driving mechanism 200 and one inspection element 100.

[0038] It should be noted that the driving direction (i.e., the second direction) of each of the second driving components 220 is the same. The driving direction (i.e., the first direction) of the first driving components 210 located on the same side edge of the inspection station is the same, but the driving directions of the first driving components 210 located on adjacent side edges of the inspection station are set perpendicularly. In other words, the driving direction of each first driving component 210 is the direction of the line connecting the frame corresponding to that first driving component 210 and the frame opposite to that frame.

[0039] like Figure 1 As shown, the detection device 10 further includes an adjustment mechanism 300, which is connected to each of the drive mechanisms 200 and is used to adjust the size of the annular detection structure. Thus, the annular detection structure can adjust its detection range according to the size of the photovoltaic module, making it applicable to photovoltaic modules of various specifications and improving the flexibility and practicality of the detection device 10.

[0040] It should be noted that both the annular detection structure and the photovoltaic module are rectangular. Different specifications of photovoltaic modules have different long sides, but the same wide side. The adjustment mechanism 300 can be configured as any existing adjustment structure capable of adjusting the size of the annular detection structure.

[0041] like Figure 1As shown, optionally, the four edges of the testing station are respectively set as a first side, a second side, a third side, and a fourth side connected vertically in sequence. The adjustment mechanism 300 includes a first slide rail 310, a second slide rail 320, and a third slide rail 330, all extending along the extension direction of the first side. The first slide rail 310 and the third slide rail 330 are spaced apart. There is at least one second slide rail 320, and each second slide rail 320 is spaced apart between the first slide rail 310 and the third slide rail 330. All drive mechanisms 200 on the first side are slidably connected to the first slide rail 310. All drive mechanisms 200 on the third side are slidably connected to the third slide rail 330. Each drive mechanism 200 on the second side is slidably connected to one end of each second slide rail 320. Each drive mechanism 200 on the fourth side is slidably connected to the other end of each second slide rail 320.

[0042] Specifically, in this embodiment, the first slide rail 310, the second slide rail 320, and the third slide rail 330 have the same structure, shape, and size. The surfaces of the first slide rail 310, the second slide rail 320, and the third slide rail 330 are all made of low-friction materials to ensure smooth sliding during the switching process of photovoltaic modules of different specifications.

[0043] like Figure 1 and Figure 2 As shown, in one embodiment, the detection device 10 further includes a glue removal mechanism 400. The glue removal mechanism 400 is disposed outside the detection station and configured to remove residual glue on the detection piece 100 during the process of the drive mechanism 200 driving the detection piece 100 to extend into and / or move out of the glue removal mechanism 400. Thus, after the detection piece 100 completes the measurement of the glue application depth in the glue application tank, the drive mechanism 200 drives the detection piece 100 to extend into the glue removal mechanism 400, enabling the glue removal mechanism 400 to promptly and automatically remove residual glue from the detection piece 100, ensuring the cleanliness of the surface of the detection piece 100, avoiding the impact of residual glue on the accuracy of subsequent detections, and improving the accuracy and reliability of the detection device 10.

[0044] Specifically, in this embodiment, the detection element 100 and the drive mechanism 200 are detachable. This allows for standardized replacement and maintenance of the detection element 100 based on the detection frequency, extending the service life of the detection device 10.

[0045] The detection component 100 can be detachably and driveably connected to the drive mechanism 200 by snap-fit, screw-fit, or other means.

[0046] like Figure 1As shown, in this specific embodiment, there are four adhesive removal mechanisms 400, which are respectively arranged on the four sides of the inspection station. In this way, the inspection pieces 100 located on the same side edge of the inspection station can share one adhesive removal mechanism 400, reducing the cost of the inspection device 10.

[0047] like Figure 1 and Figure 2 As shown, optionally, the adhesive removal mechanism 400 includes a mounting body 410. An adhesive removal groove 411 is provided on the side of the mounting body 410 near the testing station. The inner wall of the adhesive removal groove 411 is configured to scrape against the testing piece 100 during the process of the drive mechanism 200 driving the testing piece 100 to extend into and / or move out of the adhesive removal groove 411, thereby removing residual adhesive from the testing piece 100. Thus, considering the fluidity and stability of the adhesive, the residual adhesive removed from the testing piece 100 will not leak out of the adhesive removal groove 411, avoiding the impact of residue on the effectiveness of subsequent testing and improving the reliability of the testing device 10.

[0048] Specifically, in this embodiment, the extension direction of the adhesive removal groove 411 is the extension direction of the side edge of the inspection station near the adhesive removal groove 411. The width of the adhesive removal groove 411 on the side near the inspection station is smaller than the width of the adhesive removal groove 411 on the side away from the inspection station. For example, the cross-section of the adhesive removal groove 411 along its extension direction perpendicular to itself can be trapezoidal or convex. The mounting body 410 is elongated and made of an easy-to-clean material to ensure that the normal operation of the inspection piece 100 is not affected by the accumulation of residual adhesive during use. In other embodiments, cleaning cloths or cleaning sponges can also be installed inside the adhesive removal groove 411 to remove residual adhesive on the inspection piece 100.

[0049] like Figure 1 and Figure 2 As shown, in one embodiment, at least one end of the adhesive removal tank 411 extends to the end face of the mounting body 410. The adhesive removal mechanism 400 also includes a residual adhesive separator 420, which is used to clean the residual adhesive in the adhesive removal tank 411 out of the adhesive removal tank 411. Thus, when the amount of residual adhesive removed reaches a preset amount, the residual adhesive separator 420 will be automatically or manually activated to clean the residual adhesive in the adhesive removal tank 411. This ensures that the normal operation of the test piece 100 will not be affected by the accumulation of residual adhesive during use, ensures the orderly cycle of the entire testing process, reduces the frequency of manual maintenance, ensures the long-term stable operation of the equipment, and improves the practicality of the testing device 10.

[0050] Wherein, at least one end of the adhesive removal groove 411 extends to the end face of the mounting body 410. This can be one end of the adhesive removal groove 411 extending to one side end face of the mounting body 410, or both ends of the adhesive removal groove 411 extending to the two end faces of opposite sides of the mounting body 410.

[0051] like Figure 2 As shown, optionally, the residual adhesive separator 420 includes a cleaning section 421 and an operating section 422 connected to each other. The outer contour shape of the cleaning section 421 is adapted to the inner contour shape of the inner wall of the adhesive removal tank 411, and the cleaning section 421 slides in contact with the inner wall of the adhesive removal tank 411. The operating section 422 is located outside the adhesive removal tank 411. In this way, the operating section 422 can receive external driving force to drive the cleaning section 421 to slide within the adhesive removal tank 411, thereby cleaning out the residual adhesive in the adhesive removal tank 411 and improving the practicality of the detection device 10.
