[0002] Currently in the solar photovoltaic industry, aluminum frames are used to make solar photovoltaic brackets and solar aluminum profile frames. Since aluminum frames need to be assembled and matched with other photovoltaic accessories, their cut end faces will directly affect the assembly effect of photovoltaic components. Therefore, it is necessary to test the cut end faces of aluminum frames of different specifications to improve the overall product yield.
[0003] The 45° cut end face of the aluminum frame is usually measured with an angle ruler. When measuring, place the cut end face of the aluminum frame on the measuring surface of the angle ruler, observe the scale on the angle ruler, and make sure that the cut end face of the aluminum frame is aligned with the edge of the angle ruler to read the angle value. Therefore, when using an angle ruler, pay attention to keeping the aluminum frame and the angle ruler stable to avoid measurement errors caused by hand shaking or workpiece sliding. Since it is necessary to stabilize the aluminum frame and the angle ruler manually at the same time, there are often errors in the test results, and the efficiency of manual measurement is low. In addition, different specifications of aluminum frames need to be measured with different inspection tools, which increases the difficulty of operation and places high demands on operators.

[0027] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.
[0028] One or more embodiments of the present application disclose a detection device for a frame end face, which is used to measure a 45° cut angle end face 6 of an aluminum frame. Figures 1 to 4The invention comprises a detection platform 1, a limit assembly 20 and a detection assembly 10. The limit assembly 20 and the detection assembly 10 are respectively installed on the detection platform 1 along the feeding direction of the photovoltaic frame 2. The limit assembly 20 can limit the movement of the photovoltaic frame 2 along the direction of the detection assembly 10. The detection assembly 10 comprises a detection seat 11 and a measuring piece 13. The detection seat 11 is pivotally connected to the detection platform 1. The measuring piece 13 and the photovoltaic frame 2 are respectively against the two sides of the detection seat 11. When the photovoltaic frame 2 is movably against the detection seat 11 along the feeding direction through the limit assembly 20, the measuring piece 13 detects and displays the displacement of the detection seat 11. Thus, the detection device of the frame end face can quickly and effectively measure the 45° cut end face 6 of the photovoltaic frame, so as to solve or at least partially alleviate the problem of large detection error and high operation difficulty of the 45° cut end face 6 of the aluminum frame in the related art, reduce the technical and skill requirements of the detection personnel, change the professional operation mode of professional and technical personnel into the numerical detection mode of ordinary operators, and effectively improve the detection efficiency and product yield.
[0029] It should be understood that the positions of the limit assembly 20 and the detection assembly 10 are set according to the feeding direction of the photovoltaic frame 2, respectively. The detection assembly 10 is located at the terminal end of the feeding direction, and the limit assembly 20 is located on the side of the feeding direction, which is used to limit it along the long side of the photovoltaic frame 2. Among them, the long side of the photovoltaic frame 2 refers to the side along the length direction of the photovoltaic frame 2. Among them, the feeding direction of the photovoltaic frame 2 is to advance forward along the long side of the photovoltaic frame 2 until the inclined end face of the photovoltaic frame 2 abuts against the detection seat 11.
[0030] In some embodiments, reference Figure 1 As shown, the detection component 10 is installed at one end of the detection platform 1, the detection seat 11 faces the end face 6 of the photovoltaic frame 2, and the limit components 20 are distributed on the side of the photovoltaic frame 2 along the feeding direction. The limit components 20 are adjustably clamped on both sides of the longitudinal direction (vertical to the feeding direction) of the photovoltaic frame 2, so as to limit the movement of the photovoltaic frame 2 along the feeding direction, and the longitudinal degree of freedom is controlled by the limit component 20 and cannot move longitudinally, thereby preventing the photovoltaic frame 2 from deviating or moving excessively during detection. More importantly, there is no need to manually hold the photovoltaic frame 2 and the detection component 10, which effectively avoids interference from human factors. Moreover, by ensuring the stability of the photovoltaic frame 2 during the detection process, the accuracy of the measurement data is effectively improved, thereby improving the overall quality control of the photovoltaic components.
[0031] In some embodiments, reference Figure 1 and Figure 3As shown, the detection assembly 10 further includes a support shaft 12, the support shaft 12 is fixed to the detection platform 1, the detection seat 11 is rotatably connected to the support shaft 12, the end face 6 of the photovoltaic frame 2 can be against the inner surface of the detection seat 11, the measuring piece 13 is fixed to the outer side of the detection seat 11 and deviates from the photovoltaic frame 2, and the measuring end 130 of the measuring piece 13 is against the outer surface of the detection seat 11. Thus, by making the cut end face 6 of the photovoltaic frame 2 tangent to the inner surface of the detection seat 11, and then adjusting the measuring piece 13 to be fixed in a suitable position, through the principle of lever, when the cut end face 6 of the photovoltaic frame 2 and the detection seat 11 are in contact, a slight deviation between the inner surface of the detection seat 11 and the cut end face 6 will cause the measuring end 130 of the measuring piece 13 to move relatively large, thereby realizing the amplification of parameters such as displacement and angle, and by capturing this amplified size, more precise size measurement can be achieved.
[0032] In some embodiments, reference Figure 3 As shown, the detection seat 11 includes a first lateral segment 111, a second lateral segment 112 and a detection segment 113, the first lateral segment 111 and the second lateral segment 112 extend outward from both ends of the detection segment 113 respectively, the measuring end 130 of the measuring piece 13 contacts the first lateral segment 111 and / or the second lateral segment 112, the detection segment 113 is tilted relative to the central axis of the photovoltaic frame 2, the initial inclination of the detection segment 113 is consistent with the preset end face 6 angle of the photovoltaic frame 2, the inner surface of the detection segment 113 and the end face 6 of the photovoltaic frame 2 remain tangent, when the angle of the end face 6 of the photovoltaic frame 2 and the inclination of the detection segment 113 deviate, the detection seat 11 can adaptively rotate to adjust the tangent position of the detection segment 113 and the end face 6 of the photovoltaic frame 2. Thus, by deviating the position of the first side segment 111 and the second side segment 112 from the photovoltaic frame 2, the position of the measuring end 130 of the measuring piece 13 is also deviated from the detection segment 113. When there is no deviation between the inner surface of the detection segment 113 and the end face 6 of the photovoltaic frame 2, the detection segment 113 and the end face 6 of the photovoltaic frame 2 are tangent to each other, and the detection seat 11 remains stationary without rotating. When there is a deviation between the inner surface of the detection segment 113 and the end face 6 of the photovoltaic frame 2, the detection segment 113 is pressed against the end face 6 of the photovoltaic frame 2 and moves slightly, and the first side segment 111 and the second side segment 112 at the far end are converted into a larger displacement, making the measuring piece 13 easier to measure, thereby improving the sensitivity and reliability of the measurement through the amplification effect. Compared with the original method of detecting whether the angle of the end face 6 of the aluminum frame cut is qualified by using an angle ruler, the detection result can be obtained more quickly and conveniently through the detection component 10.
[0033] The central axis of the photovoltaic frame 2 is the central axis along the length direction of the photovoltaic frame 2 .
[0034] In some embodiments, the measuring member 13 includes a first dial gauge 131 and a second dial gauge 132. The first dial gauge 131 is fixed to the outside of the first lateral segment 111, and the measuring end 130 of the first dial gauge 131 contacts the first lateral segment 111. The second dial gauge 132 is fixed to the outside of the second lateral segment 112, and the measuring end 130 of the second dial gauge 132 contacts the second lateral segment 112. When the detection seat 11 rotates, the first dial gauge 131 and the second dial gauge 132 relatively display the displacement of the detection seat 11. Thus, the complementary reading changes of the two dial gauges are used to accurately measure and determine the angle change of the end face 6 of the photovoltaic frame 2. The first dial gauge 131 and the second dial gauge 132 can intuitively display the displacement. Combined with the magnification effect of the detection seat 11, high-precision inspection can be achieved, and the accuracy can reach within 0.05°, that is, when the side length is 35mm, the displacement of 0.02mm can be judged and identified.
[0035] In some embodiments, the measuring member 13 may include one or more of a digital dial indicator, a disk dial indicator, a piezoelectric sensor, or a device that displays in the form of a gear rack or the like. Among them, a digital dial indicator is a dial indicator with a digital display, which can provide a clearer and easier to read measurement result than a traditional pointer dial indicator. A digital dial indicator usually has higher accuracy and resolution, and can be connected to a computer or other device electronically to facilitate data recording and analysis; a piezoelectric sensor is a sensor that uses the piezoelectric effect to measure force or pressure. The use of a piezoelectric sensor in the measuring member 13 can very accurately detect tiny force changes, which can then be converted into electrical signals and used to calculate angles or other geometric parameters; a gear rack is a mechanical transmission system in which a gear and a rack mesh with each other to convert rotational motion into linear motion. The use of a gear rack system in the measuring member 13 can amplify tiny displacements, making the measurement results more obvious and easy to read. At the same time, the gear rack system can also be used in combination with a digital counter or display to provide accurate numerical readings. Thus, by using different measurement techniques, the most suitable measuring member can be selected according to specific measurement needs and environments. For example, in a production line environment that requires fast feedback, a digital dial indicator may be more appropriate; in a scientific research environment that requires extremely high sensitivity, a piezoelectric sensor may be a better choice; and if the requirements are not high and you only need to check whether the upper and lower limits are met, a disc dial indicator can be used, which is lower in cost.
[0036] In some embodiments, the first dial indicator 131 is substantially perpendicular to the first side segment 111, the second dial indicator 132 is substantially perpendicular to the second side segment 112, the first side segment 111 and the detection segment 113 are connected at an obtuse angle, the second side segment 112 and the detection segment 113 are connected at an obtuse angle, and the initial inclination of the detection segment 113 relative to the long side of the photovoltaic frame 2 is 45° to adapt to the 45° cut end surface 6 of the photovoltaic frame.
[0037] In some embodiments, reference Figure 2 and Figure 4 As shown, the limit assembly 20 includes a retainer 21 and a limiter 22, and the retainer 21 and the limiter 22 are installed at intervals on both longitudinal sides of the photovoltaic frame 2 to be tested, so that the photovoltaic frame 2 can be driven and clamped between the retainer 21 and the limiter 22 along the feeding direction, the retainer 21 can be driven to fit one side of the photovoltaic frame 2, and the limiter 22 can be adjusted to fit the other side of the photovoltaic frame 2. When testing photovoltaic frames 2 of different specifications, the contact area and the conductive force of the limiter 22 and the photovoltaic frame 2 can be adjusted. This improves product consistency, ensures that each photovoltaic frame 2 can maintain consistent positioning during testing, ensures the effectiveness of the detection of the cut end face 6, and thus helps to maintain the consistency and reliability of photovoltaic components.
[0038] In some embodiments, the limit assembly 20 is at least one group or may be multiple groups. According to the length of the photovoltaic frame 2, multiple pairs of retaining members 21 and limit members 22 are relatively installed along the long side of the photovoltaic frame 2, so as to more reliably limit the transmission of the photovoltaic frame 2 along the feeding direction and prevent it from moving longitudinally, thereby preventing the end face 6 of the photovoltaic frame 2 from deviating and causing invalid detection.
[0039] In some embodiments, reference Figure 5 As shown, the limit member 22 includes a shell 221, a limit wheel 223, a baffle 224, a connecting rod 225, a spring and a locking rod 226. The top and bottom of the shell 221 are provided with through holes 222 connected to the locking rod 226. The limit wheel 223 is rotatably mounted on the locking rod 226. The spring is fixed on the connecting rod 225 between the baffle 224 and the locking rod 226, so that the locking rod 226 can be longitudinally adjusted along the connecting rod 225, so that the limit wheel 223 approaches or deviates from the retaining member 21, so that the distance between the limit wheel 223 and the retaining member 21 can be elastically adjusted. The limit wheel 223 can be driven to fit the D surface 5 of the photovoltaic frame 2, thereby adapting to photovoltaic frames 2 of different specifications. The elongation of the spring and the magnitude of the conducted force to the photovoltaic frame 2 are thus determined by the distance between the locking rod 226 and the baffle 224. When the locking rod 226 is moved closer to or further away from the baffle 224, the contact area and the magnitude of the force applied between the limiting wheel 223 and the D surface 5 of the photovoltaic frame can be adjusted, so that the elastic test margin of the limiting member 22 is larger, thereby achieving the convenience of sharing photovoltaic frames 2 of various specifications and sizes, and helping to increase the versatility and flexibility of the detection device.
[0040] In some embodiments, reference Figure 4As shown, the retaining member 21 includes a fixing seat 211 and a pair of transmission wheels 212. The transmission wheels 212 are respectively installed on both sides of the fixing seat 211 along the feeding direction. The transmission wheels 212 can be driven to fit in contact with the B surface 3 of the photovoltaic frame 2, effectively reducing the resistance between the retaining member 21 and the B surface 3 of the photovoltaic frame when the photovoltaic frame 2 is pushed in for inspection, and at the same time limiting the photovoltaic frame 2 between the transmission wheel 212 and the limiting wheel 223 along the feeding direction, reducing the operating difficulty of the inspector.
[0041] The baffle plate 224 and the front plate of the housing 221 may be fixed together by fasteners such as screws, and the longitudinal movement margin of the locking rod 226 along the connecting rod 225 may be controlled by the tightening depth of the screws.
[0042] In some embodiments, the detection platform 1 is provided with a light-transmitting hole and a light source installed in the light-transmitting hole. The light-transmitting hole is opened at the detection platform 1 between the detection segment 113 and the end face 6 of the photovoltaic frame 2. A light source, such as an LED lamp, is placed in the light-transmitting hole. The light source is aimed at the gap between the detection segment 113 and the photovoltaic frame 2, so that a visual halo is formed at the joint between the inner surface of the detection seat 11 and the end face 6 of the photovoltaic frame 2 to determine whether the detection segment 113 and the end face 6 of the photovoltaic frame 2 remain in close contact, thereby achieving the purpose of visual detection.
[0043] The detection device for the frame end face is used to detect the 45° cut end face of the photovoltaic frame. The specific detection process is as follows:
[0044] (1) The C surface 4 of the photovoltaic frame is parallel to the inspection platform 1, and is pushed in along the feeding direction from the track formed by the cooperation of the retaining member 21 and the limiting member 22, without longitudinal deviation. The transmission wheel 212 of the retaining member 21 rolls in contact with the B surface 3 of the photovoltaic frame 2, and the limiting wheel 223 of the limiting member 22 rolls in contact with the D surface 5 of the photovoltaic frame 2, which helps to reduce the resistance during pushing and reduce unnecessary scratches;
[0045] (2) Push the cutout end face 6 of the photovoltaic frame 2 to fit to the inner surface of the detection seat 11. When there is a deviation in the fit between the cutout end face 6 and the detection section 113, the detection seat 11 rotates, causing the measuring end 130 of the measuring piece 13 to expand and contract, and the dial values of the first micrometer 131 and the second micrometer 132 change, intuitively displaying the rotation distance of the detection seat 11, and obtaining the angle value of the cutout end face 6 of the tested photovoltaic frame 2. Among them, the values of the first micrometer 131 and the second micrometer 132 change in opposite directions, one is an increase value, and the other is a decrease value. Through the complementary relationship, the angle relationship and size of the end face 6 of the test frame 2 are obtained;
[0046] (3) Determine whether the displayed value is between the upper limit and the lower limit. If so, the photovoltaic frame 2 is determined to be qualified. If not, and exceeds the range of the upper limit and the lower limit, the photovoltaic frame 2 is determined to be unqualified. The operation is simple, the measurement efficiency is high, and the additional cost of photovoltaic modules caused by quality problems is reduced.
