Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0041] As described in the background art, it is inconvenient to adjust the position of the test connection structure during testing, resulting in the need to replace a testing device with a matching model when the entire testing device tests display modules of different models, which affects the testing efficiency.

[0042] In order to solve this technical problem, the utility model provides an LCM adjustable electrical measurement fixture, which is applied to an LCM electrical measurement device.

[0043] Specifically, please refer to Figure 1-3 , LCM adjustable electrical test fixture specifically includes:

[0044] A support base 1, on which a slide rail base 11 is fixedly mounted;

[0045] An X-axis slide rail 2, which is fixedly mounted in the middle of the slide rail base 11;

[0046] An X-axis motion block 3, which is arranged on the X-axis slide rail 2 and slides horizontally relative to the X-axis slide rail 2;

[0047] A test component 4, which is arranged on the X-axis motion block 3 and can slide horizontally relative to the support base 1 following the X-axis motion block 3;

[0048] The locking element 5 is arranged on the slide rail base 11 and is used to lock the X-axis motion block 3 so that the X-axis motion block 3 is in a restricted state or to unlock the X-axis motion block 3 so that the X-axis motion block 3 is in a slidable state.

[0049] The utility model provides an LCM adjustable electrical testing fixture, in which an X-axis motion block 3 is arranged on an X-axis slide rail 2, a test component 4 is mounted on the X-axis motion block 3, and a locking element 5 is arranged for fixing the X-axis motion block 3. When using the device, the X-axis motion block 3 can be locked by the locking element 5 so that the X-axis motion block 3 is in a restricted state to achieve fixation, or the X-axis motion block 3 can be unlocked so that the X-axis motion block 3 is in a slidable state for position adjustment, thereby completing the position adjustment of the test component 4, so that the test position 4 corresponds to the display module. In this way, when testing different display modules, it is only necessary to adjust the position of the test component 4 to match the display module and the test component for corresponding matching detection.

[0050] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0051] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0052] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0053] Example 1

[0054] Please refer to Figure 1-5 , an LCM adjustable electrical test fixture, comprising a support base 1, a slide rail base 11, an X-axis slide rail 2, an X-axis motion block 3, a test component 4 and a locking element 5. The slide rail base 11 is fixedly mounted on the support base 1 and the X-axis slide rail 2 is fixedly mounted on the slide rail base 11. The X-axis motion block 3 is slidably mounted on the X-axis slide rail through a slider 6 so that the test component 4 can slide horizontally along the length direction of the X-axis slide rail 2. The locking element 5 is arranged on the slide rail base 11. Specifically, the locking element 5 is a limit locking bolt 51. The slide rail base 11 is provided with a thread groove matched with the limit locking bolt 51. Since the slide rail base 11 is fixed relative to the support base 1, and the X-axis motion block 3 is movable relative to the support base 1 through the slider 6, the limit locking bolt 51 can be locked and unlocked by the depth of the threaded connection with the thread groove.

[0055] Please refer to Figure 1 , Figure 2 and Figure 5The locking element 5 is arranged on the slide rail base 11 and is used to lock the X-axis motion block 3 so that the X-axis motion block 3 is in a restricted state or to unlock the X-axis motion block 3 so that the X-axis motion block 3 is in a slidable state. Specifically, an X-axis limit plate 31 is fixedly installed on the side wall of the X-axis motion block 3 by screws, and a movable groove 32 is opened in the middle of the X-axis limit plate 31. When the limit locking bolt 51 is threadedly engaged with the slide rail base 11, its inner wall can contact the X-axis limit plate 31. Preferably, the X-axis limit plate 31 is in a long strip shape and has a reliable range of motion when the X-axis motion block 3 slides, so that the entire device has better applicability.

[0056] The LCM adjustable electrical measuring fixture provided in this embodiment adopts a limit locking bolt 51 to cooperate with the X-axis limit plate 31, which has low cost and is easy to operate. When adjusting the X-axis motion block 3, the X-axis motion block 3 can be slid by screwing the limit locking bolt 51, and the position of the X-axis motion block 3 can be adjusted without removing the entire limit locking bolt 51.

[0057] Example 2

[0058] The LCM adjustable electrical measuring fixture provided in Example 1 is further optimized. Specifically, Figure 3 , Figure 4 and Figure 5 As shown, the electrical testing fixture also includes a pressure cover base 7, which is connected to the X-axis moving block 3. One side of the upper surface of the pressure cover base 7 is rotatably connected with a pressure cover 71, and the other side of the upper surface of the pressure cover base 7 is provided with a locking component 8. The locking component 8 includes a locking base 81, a buckle 82 and a rotating shaft 83. The buckle 82 is rotatably connected to the inner wall of the locking base 81 through the rotating shaft 83. One end of the pressure cover 71 has a card slot adapted to the buckle 82. The test component 4 includes a needle mold base 41 fixedly installed inside the pressure cover base 7, and the middle part of the needle mold base 41 has a connector card slot, and a probe mold 42 is also embedded and installed in the connector card slot.

[0059] Through the above-mentioned structural design, the probe mold 42 is embedded and installed in the connector slot, which can achieve effective fixation of the probe mold 42 and make the probe mold 42 and the needle mold base 41 in the same plane. In this way, it is convenient to mount the display module on the needle mold base 41 and match and connect with the probe mold 42 for testing. The pressure cover 71 can be automatically pressed down to push the buckle 82 to flip and lock it with the pressure cover 71. When it needs to be opened, press the buckle 82 to open the pressure cover 71, which can achieve effective fixation of the display module to ensure the stability and reliability of the detection.

[0060] Example 3

[0061] The LCM adjustable electrical measuring fixture provided in Example 1 or 2 is further optimized, such as Figure 1-3As shown, a gland shaft seat 72 is also installed on the gland base 7, and the gland 71 is rotatably connected to the gland shaft seat 72 by a second rotating shaft 73 inserted at the bottom thereof. The gland 71 can be flipped relative to the gland base 7 with the second rotating shaft 73 as the axis to open and close. When the gland 71 is locked with the locking component 8, a gap is formed between the bottom thereof and the test component 4. Specifically, when the gland is locked with the locking component 8, the display module is just confined between the locking component 8 and the gland 71, so that the display module can be fixed without causing damage to the display module.

[0062] Example 4

[0063] The LCM adjustable electrical test fixture provided in the above embodiments is further optimized, such as Figure 1 and Figure 2 As shown, a LCM platform 9 is fixedly installed on the support base 1, and the LCM platform 9 is used to carry the LCM during testing. Specifically, the LCM platform 9 is connected to the support base 1 and extends to the side wall of the test component 4, so that the test component and the LCM platform 9 form an integrated structure, so that the display module is placed on the LCM platform 9 more stably, thereby achieving effective support for the LCM.

[0064] The use process of the LCM adjustable electric measuring fixture provided by the utility model is as follows:

[0065] Place the display module to be tested on the LCM platform 9, and plug the detection connector on the display module with the probe mold 42 to form a connection so that it can be connected to external detection equipment for detection. At the same time, the pressure cover 71 can be closed and connected and fixed with the buckle 82 to form a restriction on the LCM to prevent the LCM from shaking and shifting. When it needs to be opened, the buckle 82 can be pressed to open the pressure cover 71. After flipping the pressure cover 71, the display module can be removed and replaced with the next display module to be tested. At the same time, when different display modules need to be tested, the limit locking bolt 51 can be opened to allow the X-axis motion block 3 to slide freely. After adjusting the test component 4 to a suitable position, the limit locking bolt 51 can be threadedly tightened to make the limit locking bolt 51 press against the X-axis limit plate 31 to complete the fixation of the X-axis limit plate 31.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0067] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model. The utility model can be implemented in many different forms.
