DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] See also Figures 1 to 3, which is the first embodiment of the utility model, and the embodiment provides a technical solution: a thickness test structure for screen printing of solar panels, comprising an ultrasonic coating thickness gauge body 1, a connecting line 2 and a thickness measuring probe 3, the model of the ultrasonic coating thickness gauge body 1 is ElektroPhysik QuintSonic 7, the thickness measuring probe 3 is connected to the ultrasonic coating thickness gauge body 1 through the connecting line 2, the thickness measuring probe 3 is located above the solar panel body 11, and also includes a support guide structure installed on the thickness measuring probe 3, the support guide structure includes a substrate 4, a movable slider 5, a fixed slider 6, a column 7 and a support rod 10, the column 7 is fixed on the top surface of the substrate 4, the support rod 10 fixes the thickness measuring probe 3 and the column 7, a movable slider 5 and a fixed slider 6 are arranged on the left side of the substrate 4, and the movable slider 5 and the fixed slider 6 are respectively slidably located on the upper and lower surfaces of the solar panel body 11 , so that the operator can subsequently achieve smooth lateral movement of the thickness measuring probe 3 by lateral movement of the substrate 4, ensuring the stability of the thickness measuring probe 3 during the test of the solar panel body 11, improving the thickness measurement accuracy, and avoiding sudden height changes. A side slide groove 42 is provided on the left surface of the substrate 4, and a guide rod 43 is fixed in the side slide groove 42. An inner slider 44 and a spring 45 are movably sleeved on the guide rod 43. One end of the inner slider 44 extends to the left side of the substrate 4 and is fixedly connected to the movable slider 5, so that the movable slider 5 and the fixed slider 6 can be clamped at the edge of the solar panel body 11.

[0020] The spring 45 is located at the top of the inner slide block 44 , and the top end of the spring 45 abuts against the top inner wall of the side slide groove 42 .

[0021] An operating handle 41 is fixed on the right side surface of the base plate 4 . The operating handle 41 is C-shaped, which facilitates subsequent operators to push the base plate 4 .

[0022] Among them, balls 12 are installed on the surfaces of the movable slider 5 and the fixed slider 6, and the balls 12 are in rolling contact with the solar panel body 11, which can reduce the friction between the movable slider 5 and the fixed slider 6 and the solar panel body 11, making it convenient for subsequent operators to translate the thickness measuring probe 3 during the thickness measurement process.

[0023] In summary, when the thickness of the surface of the solar panel body 11 needs to be tested by the thickness measuring probe 3 later, it is only necessary to lift the movable slider 5 first, so that the inner slider 44 moves up and compress the spring 45 until the edge of the solar panel body 11 can be pushed between the movable slider 5 and the fixed slider 6. At this time, the movable slider 5 is released, so that the spring 45 pushes the inner slider 44 and the movable slider 5 back, and the movable slider 5 and the fixed slider 6 can be clamped on the solar panel body 11, and the ball 12 is in rolling contact with the solar panel body 11. At this time, the substrate 4 can be moved horizontally to slide the thickness measuring probe 3 smoothly on the top of the solar panel body 11, so as to maintain the stability of the thickness measuring probe 3 during the test and avoid the situation of fluctuating up and down.

[0024] Example 2

[0025] See also Figures 1 to 4 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the height of the support rod 10 and the thickness measuring probe 3 can be adaptively adjusted by setting a movable sleeve 8 and an adjusting bolt 9.

[0026] Specifically, the left end of the support rod 10 is fixed to the side of the thickness measuring probe 3, and the right end of the support rod 10 is welded and fixed with a movable sleeve 8, and the movable sleeve 8 is slidably sleeved on the surface of the column 7. The right side surface of the movable sleeve 8 is threadedly connected with an adjusting bolt 9, and the inner end of the adjusting bolt 9 passes through the inner side of the movable sleeve 8 and is tightly fixed to the column 7 to achieve the fixation of the movable sleeve 8 and ensure the height stability of the thickness measuring probe 3. If the height of the thickness measuring probe 3 needs to be adjusted later, it is only necessary to loosen the adjusting bolt 9 counterclockwise to release the limit on the movable sleeve 8, and the movable sleeve 8 can be slid on the column 7 to change the height of the thickness measuring probe 3. After adjusting to the appropriate height, the adjusting bolt 9 is rotated clockwise and tightened to fix the thickness measuring probe 3 again.

[0027] Among them, a through-opening 81 corresponding to the column 7 is opened on the movable sleeve 8, so that the movable sleeve 8 can be smoothly mounted on the column 7. A threaded hole corresponding to the adjusting bolt 9 is opened on the right surface of the movable sleeve 8, and the threaded hole is communicated with the through-opening 81, so that the adjusting bolt 9 can be smoothly rotated and screwed in.

[0028] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
