[0002] Warping of lightweight photovoltaic modules may prevent them from being properly installed or connected, affecting the normal operation of the system and reducing structural strength. This means that when subjected to external forces or pressure, the photovoltaic modules are more likely to deform or break.

[0003] This is a potential safety hazard for applications that need to withstand heavy loads or high-pressure environments, and it can also lead to increased instability in the entire system. For example, in electronic devices, if the motherboard or other key components warp, it may cause circuit connection problems, signal interference, and reduced device performance. It may also make maintenance and repair work more difficult. For example, when performing repairs in a compact space, if the component warps and cannot be properly removed or reinstalled, it will increase repair time and costs. Therefore, when designing and manufacturing lightweight components, it is necessary to control the warpage height of the component to ensure its stability and functionality.

[0004] At present, the warping of photovoltaic modules is measured by workers using a ruler. The measurement efficiency is low and it is difficult to meet production needs. Therefore, a lightweight module warping test tool is urgently needed to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] Example 1:

[0029] Reference Figures 1 to 3 This embodiment discloses a lightweight component warpage test fixture, comprising: a foldable balance bar assembly, a displacement sensor 4 rotatably connected to the balance bar assembly, the displacement sensor 4 being located in the middle of the unfolded balance bar assembly, and the displacement sensor 4 being electrically connected to a digital display controller;

[0030] One end of the balancing pole assembly is detachably connected to the first clamping portion, and the other end of the balancing pole assembly is detachably connected to the second clamping portion.

[0031] When in use, first unfold the balance bar assembly so that the unfolded balance bar assembly is placed parallel to the short side of the photovoltaic module, and then install the first clamping part and the second clamping part on both ends of the unfolded balance bar assembly respectively, and fix the balance bar assembly to the photovoltaic module through the first clamping part and the second clamping part. The displacement sensor 4 is located in the middle of the unfolded balance bar assembly, and the displacement sensor 4 is rotated so that it is perpendicular to the surface of the photovoltaic module. After moving the device to the first measuring point of the photovoltaic module, the indication of the displacement sensor 4 is cleared to zero through the digital display controller, and then the device is moved to other measuring points. At this time, if the photovoltaic module is warped, the active end of the displacement sensor 4 will be displaced, causing the indication displayed on the digital display controller to change. When the indication exceeds the set range, it indicates that the photovoltaic module does not meet the requirements of the warping test.

[0032] The device is simple and convenient to use. The staff only needs to fix the device to the photovoltaic module, and then the displacement sensor 4 can be used for measurement, and the value will be displayed on the digital display controller, which makes it easy to obtain the warping degree of the photovoltaic module and greatly improves the measurement efficiency.

[0033] The digital display controller includes a data display screen and a PLC programmable controller. The data display screen is electrically connected to the PLC programmable controller. The displacement sensor 4 is electrically connected to the PLC programmable controller. The PLC programmable controller is an existing technology and will not be described in detail here.

[0034] A further optimized solution is that the balancing pole assembly includes two first arms 1 arranged side by side, one end of the first arm 1 is fixedly connected to a rotation shaft 3, the rotation shaft 3 is located between the two first arms 1, and the rotation shaft 3 is rotatably connected to one end of a second arm 2, and the thickness of the second arm 2 matches the gap between the two first arms 1;

[0035] The displacement sensor 4 is rotatably connected to the end of the rotating shaft 3 .

[0036] When the device is finished using, the balance bar assembly needs to be folded. First, the first clamping part and the second clamping part are removed, and then the second arm 2 is rotated between the two first arms 1 through the rotating shaft 3 to complete the storage of the device.

[0037] According to a further optimized solution, the first clamping portion includes a first clamp 5 , and the first clamp 5 is fixed to an end of the second arm 2 away from the first arm 1 by bolts.

[0038] According to a further optimized solution, the first clamp 5 is an L-shaped structure, and a through hole for the bolt to pass through is opened on the vertical section of the first clamp 5.

[0039] The first clamp 5 is an L-shaped structure, and a through slot is provided in the vertical section of the first clamp 5 for the end of the second arm 2 to pass through. Through holes are provided on the front and rear sides of the through slot for the bolts to pass through. The end of the second arm 2 is also provided with a through hole for the bolts to pass through. By inserting the end of the second arm 2 into the through slot of the first clamp 5, and then passing the bolts through the first clamp 5 and the second arm 2 in turn, and tightening the bolts, the fixation of the two can be completed.

[0040] According to a further optimized solution, the second clamping portion includes a second clamp 6 , and the second clamp 6 is fixed to the ends of the two first arms 1 away from the second arms 2 by bolts.

[0041] According to a further optimized solution, the second clamp 6 is a U-shaped structure, and a through hole for the bolt to pass through is opened on the top horizontal section of the second clamp 6.

[0042] The second clamp 6 is a U-shaped structure, with the top horizontal section of the second clamp 6 inserted into the gap between the two first arms 1. Through holes for bolts are provided on both the first arms 1 and the second clamp 6. Once the second clamp 6 and the two first arms 1 are joined, bolts are passed through the through holes to secure them.

[0043] The solution is further optimized, and the lengths of the first arm 1 and the second arm 2 are matched. When the first arm 1 and the second arm 2 are unfolded, the total length matches the width of the photovoltaic module.

[0044] According to a further optimized solution, a ball head 7 is fixed to the movable end at the bottom of the displacement sensor 4 , and the ball head 7 is used to contact the surface of the photovoltaic module.

[0045] The arrangement of the ball head 7 can prevent the displacement sensor 4 from scratching the surface of the photovoltaic module.

[0046] When in use, the device can also be set on the production line of photovoltaic modules. The first arm 1 and the second arm 2 are fixed on the production line by the first clamp 5 and the second clamp 6, so that the photovoltaic module passes through the bottom end of the displacement sensor 4. The displacement sensor 4 records the rate of change of the photovoltaic module when it passes. When the rate of change is large, it indicates that the photovoltaic module does not meet the warping requirements. Through such a setting, automatic detection can be achieved, replacing manual labor, reducing costs and increasing efficiency.

[0047] Example 2:

[0048] refer to Figures 4 and 5 The difference between this embodiment and embodiment 1 is that a first rectangular slide groove 8 is opened in the middle of the first extension arm 1, and a second rectangular slide groove 10 is opened in the middle of the second extension arm 2. First rectangular sliders 9 are respectively fixed to the front and rear sides of one end of the second extension arm 2. The first rectangular slider 9 is horizontally slidably connected to the corresponding first rectangular slide groove 8. The middle of the second rectangular slide groove 10 is slidably connected to the middle of the second rectangular slider 11. The front and rear ends of the second rectangular slider 11 are respectively slidably connected to the corresponding first rectangular slide groove 8. The rotating shaft 3 is arranged through the second rectangular slider 11. The end of the rotating shaft 3 away from the displacement sensor 4 is provided with a thread, and the rotating shaft 3 thread is matched with a nut 12.

[0049] Taking into account that the size of photovoltaic modules varies depending on the production line, on the basis of Example 1 of this case, a first rectangular slide groove 8 is opened in the middle of the first arm 1, and a second rectangular slide groove 10 is opened in the middle of the second arm 2. The first rectangular slider 9 is fixed to the front and rear sides of one end of the second arm 2 respectively, and the first rectangular slider 9 is made to slide in the corresponding first rectangular slide groove 8, thereby realizing the sliding setting of the first arm 1 and the second arm 2, that is, meeting the storage requirements, and the effective total length of the first arm 1 and the second arm 2 can also be changed by relative sliding to adapt to photovoltaic modules of different sizes.

[0050] The second rectangular slider 11 slides within the first rectangular slot 8 and the second rectangular slot 10, changing the position of the displacement sensor 4 and facilitating its adjustment to the center of the photovoltaic module to be measured. By tightening the rotating shaft 3 and the nut 12, the distance between the displacement sensor 4 and the nut 12 decreases, squeezing the second arm 2 and the two first arms 1, thereby fixing the angle and position of the displacement sensor 4 and the effective total length of the first arm 1 and the second arm 2. The device is then connected to the photovoltaic module with the first clamp 5 and the second clamp 6, allowing for convenient measurement of photovoltaic modules of various sizes.
