[0002] In the production of solar photovoltaic modules, photovoltaic glass is a crucial component, especially in double-glass modules. If both the front and rear glass panels are not flat enough, the solar cells can easily shatter under the pressure of the two panes.

[0020] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please refer to the following: Figure 1 and Figure 2The photovoltaic glass flatness testing device provided by this utility model will now be described. The photovoltaic glass flatness testing device includes a rotating robotic arm 1, a supporting platform 13, and a movable feeler gauge 5 unit. The rotating robotic arm 1 is provided with telescopic arms 2 that extend and retract in the vertical direction at both ends. Vacuum suction cups 3 for adsorbing glass 14 and pressing blocks 4 for pressing glass 14 are respectively provided on the two telescopic arms 2. The supporting platform 13 is used to place the glass 14 to be tested. The movable feeler gauge 5 unit includes a feeler gauge 5 and a first slide rail 9 that drives the feeler gauge 5 to move parallel to the edge of the glass 14. The first slide rail 9 is provided at the edge of the supporting platform 13. A second slide rail 8 perpendicular to the first slide rail 9 is also provided on the first slide rail 9. The feeler gauge 5 is installed on the second slide rail 8. The second slide rail 8 drives the feeler gauge 5 away from or towards the glass 14.

[0022] The photovoltaic glass flatness testing device provided by this utility model has the following advantages compared with the prior art: This application integrates automatic feeding and automatic testing functions. A vacuum suction cup 3 picks up the glass 14 to be tested, and the rotating robotic arm 1 places the glass 14 on the support platform 13. A telescopic arm 2 presses the pressure block 4 onto the glass 14. Then, the first slide rail 9 drives the second slide rail 8 to move parallel to the edge of the glass 14. A feeler gauge 5 is inserted into the gap between the support platform 13 and the glass 14 via the second slide rail 8, allowing the reading of the feeler gauge 5 to detect the flatness of the glass 14. This device has a simple structure, is easy to use, and can achieve automatic testing, improving testing efficiency and promptly identifying and removing defective glass 14, avoiding breakage in subsequent production lines and reducing production costs.

[0023] This application has a simple structure and is easy to assemble. The slide rail can be a suitable electric slide table to achieve linear reciprocating movement. The vacuum suction cup 3 supplies vacuum through a vacuum pump, picks up the glass 14, and slowly places the glass 14 onto the support platform 13 by rotating the rotating mechanical arm 180°. The rotating mechanical arm 1 can rotate 360°. The rotating mechanical arm 1 is fixed to the column, and the column is fixed to the rotating disk. The rotating disk is driven by a drive motor to drive the pinion to rotate. The pinion meshes with the gear ring of the rotating disk to drive the rotating disk to rotate, thereby driving the column and the rotating mechanical arm 1 to rotate. Then, the glass 14 is picked up and lifted by the descent of the telescopic arm 2, and then rotated to the top of the support platform 13 to put the glass 14 down. Then, it rotates back to the position of picking up the glass 14. At this time, the pressure block 4 rotates back to the top of the support platform 13 and presses on the glass 14 by the extension of the telescopic arm 2.

[0024] Optionally, the column can be directly connected to the upright spindle of the drive motor. The drive motor is fixed through the base and can also drive the column to rotate, thereby driving the rotary robotic arm 1 to rotate.

[0025] In this application, the vacuum suction cup 3 includes multiple small suction cups, which are connected to each other through branch pipes. All branch pipes are connected to the middle pipe, and the vacuum pump is connected to the middle pipe through a flexible tube. The small suction cups can be distributed in a circular or rectangular shape to increase the contact area with the glass 14, thereby facilitating the stable suction of the glass 14.

[0026] In some embodiments, the lower surface of the pressure block 4 is provided with a buffer pad layer that contacts the glass 14. The buffer pad layer has an elastic cushioning effect, which can prevent the pressure block 4 from damaging the glass 14.

[0027] In some embodiments, see Figure 1 and Figure 2 Movable feeler gauge units 5 are respectively installed on opposite sides of the bearing platform 13. Flatness can be measured simultaneously on opposite sides of the glass 14, which not only improves the efficiency of flatness inspection, but also improves the comprehensiveness of inspection points, thereby preventing uneven glass 14 from entering subsequent production.

[0028] In some embodiments, see Figure 1 and Figure 2 The feeler gauge 5 is a wedge-shaped feeler gauge 5. Only one wedge-shaped feeler gauge 5 is needed. It is used to obtain the value of glass 14 bending by the depth of insertion into the gap. It is simple and convenient to operate.

[0029] In some embodiments, see Figure 1 and Figure 2 The second slide rail 8 is equipped with a clamping seat 7 for holding the feeler gauge 5. The clamping seat 7 has a slot for holding the feeler gauge 5 and a locking screw 6 for locking the feeler gauge 5. The clamping seat 7 can also be a suitable gripper cylinder. The gripper cylinder is installed on the slider of the second slide rail 8, and the second slide rail 8 is installed on the slider of the first slide rail 9.

[0030] In some embodiments, see Figure 1 and Figure 2 The clamping base 7 is also equipped with a limiting block 15 that stops at the handle end of the feeler gauge 5 along the moving direction of the second slide rail 8. The limiting block 15 is located at the end of the groove away from the glass 14. By setting the limiting block 15, when the feeler gauge 5 is inserted into the gap between the glass 14 and the marble slab, the reaction force that would cause the feeler gauge 5 to move backward can be avoided, ensuring the accuracy of the flatness measurement value, thereby preventing uneven glass 14 from entering and causing fragmentation problems in subsequent processes.

[0031] In some embodiments, see Figure 1 and Figure 2 The telescopic boom 2 is a lifting cylinder. The telescopic boom 2 has the function of lifting the pressure block 4, and can be directly selected from cylinders, hydraulic cylinders or electric push rods to achieve the lifting function; the telescopic boom 2 can also be selected from worm gear lifting mechanism or screw lifting mechanism, or a linear slide table can be used for lifting action.

[0032] In some embodiments, see Figure 1 and Figure 2 The supporting platform 13 includes a support frame 10 and a marble slab mounted on the support frame 10. This invention uses a marble slab to test the flatness of the glass 14, resulting in a simple structure and convenient use. Specifically, in use, a vacuum pump operates, and the operation button controls the vacuum suction cup 3 to pick up the glass 14. The glass 14 is then slowly placed on the marble slab. A feeler gauge 5 is then inserted into the gap between the glass 14 and the marble slab, and the reading on the feeler gauge 5 is taken to test the flatness of the glass 14. This method provides a more intuitive and efficient test.

[0033] See Figure 1 and Figure 2 The support frame 10 of this application includes four pillars 16. A support plate 12 for mounting a first slide rail 9 is provided on the outer side of the pillars 16. The two ends of the first slide rail 9 are mounted on the support plate 12. Then, a second slide rail 8 is mounted on the first slide rail 9, and a clamping seat 7 is mounted on the second slide rail 8. In order to ensure the stability and reliability of the support plate 12, an oblique reinforcing rod 11 is also provided between the support plate 12 and the pillars 16.

[0034] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
