Description

Against this background, positioning devices for LCD screens came into being.

[0003] Most of the existing positioning devices for LCD liquid crystal display screens are composed of a positioning platform, a driving structure, a clamping structure and the like. For example, the Chinese patent with publication number CN218512741U and name: A positioning tool based on LCD liquid crystal display processing, is to rotate the adjusting screw so that the end of the adjusting screw moves spirally inside the driving rack, so that the driving rack slides inside the second positioning ring, and the driving rack drives the adjusting gear to rotate, so that the two sets of connecting racks drive the two sets of positioning baffles to move synchronously to the middle, and finally the two sets of positioning baffles push the display screen to the middle position and clamp the display screen. However, during its actual use, it is necessary to manually place its LED display screen on the processing carrier plate. At this time, the specific positions placed by different operators in different situations are prone to slight differences, and then it is impossible to accurately define its longitudinal position. At the same time, due to the different torsional forces of the operator's hands, the driving force applied during the rotation adjustment is also different, so it is easy to cause the clamping to be loose and offset or the clamping force is too large to cause damage to the LED display screen. Therefore, the present application provides an easy-to-use LCD liquid crystal display positioning device to meet the needs. Utility Model Content

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0028] Combine the following Figure 1-4 The embodiment shown describes the technical solution of the utility model:

[0029] It includes a positioning frame 1, the interior of the positioning frame 1 is slidably connected to the same pushing plate 3 through two electric slide rails 2, and the side walls of the pushing plate 3 are slidably connected to two clamping members 5 through driving slide rails 4, the two clamping members 5 are used to clamp the LED display screen, the top of the pushing plate 3 is fixedly connected to an optical sensor 7 through a mounting member 6, and the optical sensor 7 is used to detect the size of the LED display screen clamped between the two clamping members 5, positioning plates 9 are arranged on both sides of the positioning frame 1, and a first electric push rod 8 is used for the two positioning plates 9 to move linearly in opposite directions inside the positioning frame 1, the two positioning plates 9 are used to limit the LED display screen, and a displacement sensor 10 is arranged on the positioning plate 9.

[0030] Before using it, the positioning frame 1 can be directly placed on a plane, so that the LED display screen to be detected can be directly placed inside the pushing plate 3. At this time, the optical sensor 7 can be directly turned on, so that the optical sensor 7 can effectively obtain the size information of the LED display screen by measuring the change of the light signal. At this time, its information can be transmitted to the controller, so that the controller controls the driving slide rail 4 to drive the clamping member 5 to move, so that the two clamping members 5 move linearly in opposite directions, and then quickly clamp the LED display screen from both sides. The external controller will also simultaneously drive the electric slide rail 2 to adjust the pushing plate 3, so that the pushing plate 3 drives the LED display screen to move linearly inside the positioning frame 1, so that the center of the LED display screen and the center of the positioning frame 1 are located on the same longitudinal axis. At this time, the first electric push rod 8 will also push the two positioning plates 9 to move relative to each other under the action of the controller, and then the LED display screen can quickly clamp it, so that the positioning operation of the LED display screen can be completed, ensuring the stability of the LED display screen during use or detection, maintenance and processing.

[0031] A groove is formed on one opposite side of the two clamping members 5 , and a protective pad 23 is fixedly connected to the inside of the groove via a pressure sensor 24 . The size of the protective pad 23 and the pressure sensor 24 is the same as that of the groove.

[0032] When the clamping member 5 is moved under force, it can drive the protective pad 23 and the pressure sensor 24 to move synchronously, and then when the clamping member 5 clamps the LED display screen, its clamping and fixing force will react on the pressure sensor 24, so that the pressure sensor 24 detects the clamping pressure, and then its signal can be transmitted to the controller, so that the controller can autonomously drive the driving slide rail 4 to stop, thereby ensuring the stability of the position of the clamping member 5, avoiding the possibility of the clamping member 5 storing too large or too small clamping force during clamping, and improving its overall stability to a certain extent.

[0033] A positioning clamping groove is provided on the top of the positioning frame 1 , and the pushing plate 3 and the positioning plate 9 are respectively located on both sides of the positioning clamping groove. The size of the positioning plate 9 is half of the size of the positioning clamping groove.

[0034] Therefore, when the electric slide rail 2 drives the pushing plate 3 to be placed in a suitable position, the center of the LED display screen will coincide with the center of the positioning frame 1 and the positioning clamping groove. At this time, when the positioning plate 9 is subjected to force to move and hold, it can effectively fit with the side wall of the LED display screen. At this time, the two positioning plates 9 and the two clamping members 5 will clamp the four corners of the LED display screen respectively to prevent the positioning plate 9 from contacting the pushing plate 3 and the clamping members 5, thereby affecting the overall holding effect.

[0035] A storage cavity 11 is formed on the side wall of the positioning plate 9 , and the storage cavity 11 passes through one side of the positioning plate 9 . A connecting plate 12 is slidably inserted into the storage cavity 11 .

[0036] During the clamping period, if the LED display screen is inspected or processed and repaired, if the pushing plate 3 affects its operating point, the electric slide rail 2 can be used to directly drive the pushing plate 3 to move, so that the clamping member 5 on the pushing plate 3 will cancel the support of the LED display screen, and let the pushing plate 3 reset itself. At this time, the connecting plate 12 can be directly pulled to be pulled out along the storage cavity 11 under force, and then the LED display screen is clamped, thereby increasing the support area of ​​the positioning plate 9 and ensuring the stability of the LED display screen.

[0037] A mounting opening is formed on the side wall of the connecting plate body 12 , and an elastic clamping plate 13 is fixedly connected inside the mounting opening. The elastic clamping plate 13 is supported by an elastic material and has an oblique section.

[0038] The elastic clamping plate 13 made of elastic material can effectively increase the contact friction between the connecting plate body 12 and the LED display screen, making it more stable during clamping. At the same time, the setting of the oblique section also makes the overall recycling process more convenient when the connecting plate body 12 is recycled after clamping.

[0039] A guide member 14 is fixedly connected to the top of the connecting plate body 12 , and the storage cavity 11 passes through the bottom of the positioning plate body 9 , and the guide member 14 can slide along the storage cavity 11 .

[0040] When the connecting plate body 12 is forced to move, its moving force will act on the guide member 14, so that the guide member 14 is forced to slide along the storage cavity 11. At this time, the sliding force between the storage cavity 11 and the guide member 14 will effectively limit the moving trajectory of the connecting plate body 12 to ensure the stability of the connecting plate body 12 during adjustment and avoid the possibility of its deviation.

[0041] A connecting member 15 is fixedly connected to the top of the positioning plate 9 , and a second electric push rod 16 is fixedly connected to the side of the connecting member 15 opposite to the guide member 14 . The second electric push rod 16 is used to drive the guide member 14 to move.

[0042] During its use, the second electric push rod 16 can be directly controlled by an external controller. At this time, the second electric push rod 16 will effectively push the connecting plate body 12 to move through the guide member 14, thereby simplifying the steps of moving and adjusting the connecting plate body 12, making its overall operation more convenient.

[0043] The side wall of the positioning frame 1 is provided with two accommodating cavities 17, and the interior of the accommodating cavity 17 is rotatably connected to a support frame 18, the side wall of the positioning frame 1 is fixedly connected to a concave storage rack 19, and the interior of the concave storage rack 19 is slidably connected to a clamping member 21 through a telescopic member 20, the side wall of the clamping member 21 is provided with two clamping plates 22, and the free end of the support frame 18 can be clamped inside the clamping plate 22.

[0044] During its use, the engaging member 21 can be directly pulled so that the force drives the telescopic member 20 to deform, thereby making the telescopic member 20 extend and allowing the engaging member 21 to fall off the inside of the concave storage rack 19, so that the support frame 18 can be directly pulled so that it is forced to rotate along the accommodating cavity 17, thereby changing the angle between the positioning frame 1 and the support frame 18. At this time, the support frame 18 is simplified to rotate to the inside of the engaging plate 22 and engages with the engaging plate 22, so that the positioning frame 1, the support frame 18 and the telescopic member 20 form a triangular structure, which can effectively place the positioning frame 1 vertically on a plane, thereby changing the overall usage form, meeting the usage requirements of different occasions, and improving the overall convenience of use.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
