[0016] The present invention will be further described in detail below with reference to the accompanying drawings.
[0017] like Figures 1-3 As shown, the calibration test fixture mainly includes a support plate 1 and two support blocks 2. The support plate 1 is horizontally arranged and roughly square, and the two ends of the support plate 1 are respectively mounted on the two support blocks 2, and the support plate 1 and each support block 2 are composed of conductors.
[0018] A recessed groove 11 is formed in the center of the support plate 1 , and the screen 4 to be tested is placed in the groove 11 . Therefore, the shape of the groove 11 is the same as that of the screen 4 , and the size of the groove 11 is slightly larger than that of the screen 4 .
[0019] In the middle of the groove 11 there is a through opening 12 which passes through the upper and lower sides of the support plate 1 . The groove 11 and the screen 4 therein can be easily separated through the through opening 12 .
[0020] Preferably, the through-opening 12 is a stepped rectangular opening.
[0021] More preferably, circular notches 13 are provided at the corners of the through-opening 12 to facilitate the smooth separation of the screen 4 from the groove 11.
[0022] An indented handle groove 14 is further formed on the support plate 1. The handle groove 14 communicates with the middle of one side of the groove 11. Through the handle groove 14, it is further convenient to place or take out the screen 4 into or from the groove 11.
[0023] In addition, a rotary buckle 3 is installed at each corner of the support plate 1. The rotary buckle 3 includes a rotary head 31 and a clamping block 32. The rotary head 31 is installed on the support plate 1 and can rotate, and the clamping block 32 is connected to the side of the rotary head 31.
[0024] When the screen 4 is placed in the groove 11, the clamping blocks 32 of the rotary buckles 3 can be respectively rotated above the corners of the groove 11, so as to fix the screen 4 in the groove 11, prevent it from shaking and other changes during the test, and protect it from being damaged during the test.
[0025] A set of two indented draw grooves 21 are respectively provided on the opposite side surfaces of the two support blocks 2. One end of each draw groove 21 respectively penetrates through this end surface (the front end in the attached drawing) of the two support blocks 2. Then, when in use, the electrode plate 5 can be inserted from the penetration at this end surface. The two ends of the electrode plate 5 are respectively located in a set of two draw grooves 21, and the electrode plate 5 can be conveniently drawn out and then inserted reversely.
[0026] Preferably, two sets of draw grooves 21 are respectively provided at different heights on the opposite side surfaces of the two support blocks 2, and the draw grooves 21 at different heights can be selected for use according to needs.
[0027] When using this calibration test tooling, the screen 4 to be tested is placed into the groove 11 of the support plate 1, and fixed by using the rotary buckles 3. Then, the electrode plate 5 is inserted into a set of draw grooves 21 on the two support blocks 2 below, so that the electrode plate 5 is connected to the screen 4 to be tested.
[0028] After the test is completed, the rotary buckles 3 are rotated open. The screen 4 can be conveniently taken out through the through-opening 12 and the handle groove 14, and the electrode plate 5 is drawn out from the draw grooves 21.
[0029] A screen calibration test tooling in the present utility model mainly has the following beneficial effects:
[0030] 1. The overall mechanism design simplifies the complex tooling and reduces the production cost on the basis of completing the screen calibration test;
[0031] 2. By setting a groove on the support plate to place the screen, the screen can be more easily positioned on the tooling.
[0032] 3. By using a rotating buckle, no accidental events will occur during the testing process.
[0033] 4. By using a slot to insert and flip the electrode plate, the operation is not only convenient but also space-saving.
[0034] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the inventive concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model.
