Description

Technical Field

[0001] This utility model relates to the field of automated testing equipment technology, and in particular to a display screen support mechanism for automated testing equipment. Background Technology

[0002] In the field of automated testing equipment, especially in the quality inspection of products such as LCD screens, support mechanisms are needed to position and fix the screen under test to ensure that the screen remains stable during the test so that automated equipment can perform optical inspection, functional testing or durability testing.

[0003] Existing display support mechanisms typically have a certain degree of adjustability to accommodate displays of different sizes or models. This adjustment is usually achieved through movable support arms or clamps. However, after adjustment, how to securely lock these movable parts in a specific position is the key to ensuring test accuracy.

[0004] Currently, many support mechanisms are fixed using simple friction locking or manual screw tightening. In high-frequency use or vibration environments during automated testing, this method is prone to loosening or displacement, causing the supported display screen to tilt, deform, or even leak light, seriously affecting the accuracy and consistency of test data, and the operation is not convenient or efficient enough.

[0005] Therefore, this utility model proposes a display screen support mechanism for automated testing equipment to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the display screen support mechanism of automated testing equipment, such as difficulty in adapting to different sizes and models of display screens, cumbersome adjustment and fixing operations, and easy displacement, deformation or light leakage after fixing, this utility model aims to provide a display screen support mechanism for automated testing equipment with an improved structure that can effectively solve the above problems, especially a support mechanism with adjustable and reliable locking functions.

[0007] This utility model provides a display screen support mechanism for automated testing equipment, including a Y support, an X segment support-R, an X segment support-L, a mounting base, a rotating shaft, and two fixing components.

[0008] The Y-support serves as the bottom foundation of the entire mechanism. The X-segment supports-R and X-segment supports-L are slidably mounted on the Y-support to support and adjust the support width of the display screen. Positioning holes are provided on both the X-segment supports-R and X-segment supports-L. The mounting base is fixedly connected to the Y-support, and the rotating shaft is rotatably connected to the mounting base.

[0009] The fixing assembly includes a pressure plate, a mounting ring, a knob, a rotating component, a locking block, and a spring. The pressure plate is fixedly connected to one side of the rotating shaft and is used to press down the X-segment support-R and X-segment support-L after rotation. The mounting ring is fixedly connected to the pressure plate. The knob is rotatably connected inside the mounting ring. The rotating component is fixedly connected to the bottom of the knob. The locking block is slidably disposed inside the rotating component. The spring is housed inside the rotating component, with one end abutting against the inner wall of the rotating component and the other end abutting against the locking block.

[0010] The rotating shaft, the pressure plate, the mounting ring, and the knob cooperate with each other through a rotating connection to achieve the initial clamping and locking mechanism of the X-segment support. The locking block extends out of the rotating part under the push of the spring, thereby locking into the positioning holes on the X-segment support-R and X-segment support-L. This locking mechanism achieves fast and high-precision stable locking of the adjustable support.

[0011] Preferably, the surface of the pressure plate is provided with an alignment mark, which is preferably a scribed line or a groove, used to indicate the position of the knob when it is rotated, so that the operator can intuitively confirm whether the locking state is in place.

[0012] Preferably, a limiting seat is fixedly connected to the end of the rotating shaft away from the pressure plate. The size of the limiting seat is larger than the hole through which the rotating shaft passes through the mounting base, so that the limiting seat abuts against the inner wall of the mounting base, effectively preventing the rotating shaft from axially moving or coming off during use.

[0013] Preferably, two locking blocks and a spring are symmetrically arranged inside the rotating component. The two locking blocks slide in opposite directions along the radial direction of the rotating component. This symmetrical structure makes the force more uniform after fixing, improving the stability and anti-shaking ability of the support mechanism.

[0014] Preferably, the display screen support mechanism for the automated testing equipment further includes a partition, which is vertically disposed on the Y support, and the X segment support-R and the X segment support-L are slidably adjusted along the surface of the partition, and the partition provides precise guidance for the adjustment of the X segment support.

[0015] Preferably, the upper surfaces of both the X-segment support-R and the X-segment support-L are provided with protruding plates. The structure of the protruding plates overlaps and cooperates with the upper surface of the adjacent X-segment support-R or X-segment support-L. The design of the protruding plates can effectively prevent the X-segment supports from becoming disengaged due to operational errors or vibrations during vertical adjustment.

[0016] Preferably, the display screen support mechanism for the automated testing equipment includes two mounting bases, which are spaced apart along the length of the Y-support, and both mounting bases are rotatably connected to the rotating shaft. This double-sided fixing method greatly enhances the stability and rigidity of the overall structure.

[0017] Preferably, the X-segment support-R and the X-segment support-L are made of metal materials or engineering plastics with high strength and wear resistance to ensure that they have sufficient load-bearing capacity and service life in long-term automated testing environments.

[0018] Preferably, the bottom of the Y-support is provided with multiple mounting holes, which are used to bolt the automated testing equipment display support mechanism to the automated testing platform, facilitating the installation and integration of the mechanism.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model solves the problem that the support mechanism in the prior art is difficult to adapt to different sized displays and the fixation is unreliable by setting a sliding X-segment support and using a pressure plate to press it and a locking mechanism composed of a knob, rotating part, spring and card block to fix it. It achieves the technical effect of being able to flexibly adjust the support width and achieve quick and stable locking by the card block being inserted into the positioning hole.

[0021] 2. This utility model solves the problem in the prior art that the locking operation cannot be intuitively confirmed as in place by setting an alignment mark on the pressure plate, thus achieving the technical effects of convenient operation, clear and visible locking status, and improved operational reliability.

[0022] 3. This utility model solves the problem that the support structure in the prior art is prone to causing the display screen to deform or produce light leakage by setting the Y support and the adjustable X segment support to always be flush and fit together, and using the partition for guidance. It achieves the technical effect of stable support, tight fit and effective prevention of test interference. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please refer to Figures 1 to 5 This utility model provides a display screen support mechanism for automated testing equipment, which aims to solve the problems of inconvenient adjustment and unreliable fixation of existing display screen support mechanisms when adapting to different sized display screens, which can easily lead to displacement, deformation or light leakage of the display screen during testing.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the display screen support mechanism of the automated testing equipment includes a Y support 5, and X segment supports-R1 and X segment supports-L2 slidably disposed on the Y support 5. The Y support 5 serves as the mounting base 7 of the entire device, providing a stable support platform for other components. The X segment supports-R1 and X segment supports-L2 are used to support the display screen and realize the sliding adjustment of its position. Two mounting bases 7 are fixedly connected to the upper surface of the Y support 5. The mounting bases 7 are used to install the relevant components of the two fixing components 6. The X segment supports-R1 and X segment supports-L2 are both provided with positioning holes 601. The positioning holes 601 are used to cooperate with the locking blocks 610 of the fixing components 6 to achieve locking.

[0033] The mechanism also includes a partition 4, which is vertically mounted on the Y support 5. The X segment support-R1 and X segment support-L2 slide and adjust along the surface of the partition 4 to accommodate displays of different sizes. The surfaces of the X segment support-R1 and X segment support-L2 are provided with protruding plates 3. The protruding plates 3 overlap and cooperate with the adjacent X segment support-R1 or X segment support-L2 to prevent disengagement during adjustment.

[0034] Each mounting base 7 is rotatably connected to a rotating shaft 602. One end of the rotating shaft 602 is fixedly connected to a limiting seat 604, which abuts against the mounting base 7 to prevent the rotating shaft 602 from coming out of the mounting base 7. The other end of the rotating shaft 602 is used to connect to the fixing component 6.

[0035] The fixing component 6 includes a pressure plate 603, which is fixedly connected to the side of the rotating shaft 602 away from the limiting seat 604. The pressure plate 603 is used to press down the X segment support-R1 and the X segment support-L2 after rotation. The upper surface of the pressure plate 603 is fixedly connected to the mounting ring 606. The surface of the pressure plate 603 is also provided with an alignment mark 605, which is used to indicate the rotation position of the knob 607.

[0036] The knob 607 is rotatably connected to the mounting ring 606. The bottom of the knob 607 is fixedly connected to a rotating component 608. The rotating component 608 contains a locking block 610 and a spring 609. The locking block 610 is slidably disposed in the rotating component 608. The spring 609 is disposed in the rotating component 608, with one end abutting against the inner wall of the rotating component 608 and the other end abutting against the locking block 610. Two sets of locking blocks 610 and springs 609 are symmetrically arranged in the rotating component 608.

[0037] In the assembled state, when the knob 607 is rotated to the locking position flush with the alignment mark 605, the rotating component 608 drives the locking block 610 to rotate to the corresponding position. The spring 609 pushes the locking block 610 out of the rotating component 608 and into the positioning holes 601 of the X segment support-R1 and X segment support-L2, ensuring that the X segment support-R1 and X segment support-L2 are firmly fixed after adjustment, preventing them from sliding during the test.

[0038] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0039] As a preferred embodiment, please refer to Figure 4 The surface of the pressure plate 603 is provided with an alignment mark 605, which is preferably a groove or a stencil. A corresponding mark is provided on the knob 607 to indicate the rotation position of the knob 607.

[0040] As a preferred embodiment, please refer to Figure 2 and Figure 3 The end of the rotating shaft 602 away from the pressure plate 603 is fixedly connected to a limiting seat 604. The diameter of the limiting seat 604 is larger than the hole through which the rotating shaft 602 passes through the mounting base 7, so that the limiting seat 604 abuts against one side wall of the mounting base 7.

[0041] As a preferred embodiment, please refer to Figure 5 Two sets of locking blocks 610 and springs 609 are symmetrically arranged inside the rotating component 608. The two sets of locking blocks 610 are slidably arranged in opposite directions along the radial direction of the rotating component 608.

[0042] As a preferred embodiment, please refer to Figure 1 The mechanism also includes a partition 4, which is vertically fixed to the Y support 5 and located between the X segment support-R1 and the X segment support-L2. The inner sidewalls of the X segment support-R1 and the X segment support-L2 are respectively attached to the two side surfaces of the partition 4 for sliding adjustment.

[0043] As a preferred embodiment, please refer to Figure 1 Both the upper surfaces of the X-segment support-R1 and the X-segment support-L2 are provided with protruding plates 3.

[0044] As a preferred embodiment, in reference to Figure 1 The structure of the convex plate 3 overlaps and matches the upper surface of the adjacent X segment support-R1 or X segment support-L2.

[0045] As a preferred embodiment, please refer to Figure 2 The display support mechanism for the automated testing equipment also includes two mounting bases 7, which are spaced apart along the length of the Y support 5. Both mounting bases 7 are fixedly connected to the Y support 5, and both mounting bases 7 are rotatably connected to a rotating shaft 602.

[0046] Working principle: When it is necessary to support LCD screens of different sizes, the operator can slide and adjust the X segment support-R1 and X segment support-L2 along the surface of the partition 4 vertically set on the Y support 5 to adapt to the width of the LCD screen. During the adjustment process, the protruding plate 3 on the X segment support-R1 and X segment support-L2 overlaps and cooperates with the adjacent X segment support-R1 or X segment support-L2 to prevent the X segment support-R1 and X segment support-L2 from disengaging during the adjustment process.

[0047] After adjustment, rotate the shaft 602 connected to the mounting base 7. The shaft 602 drives the pressure plate 603 fixedly connected to one side to rotate until the pressure plate 603 presses against the X segment support-R1 and X segment support-L2. During rotation, the limiting seat 604 at the other end of the shaft 602 abuts against the mounting base 7 to prevent the shaft 602 from coming off. Then, rotate the knob 607 rotatably connected inside the mounting ring 606 fixedly connected to the pressure plate 603. The knob 607 drives the rotating part 608 fixedly connected to its bottom to rotate together. When the knob 607 is rotated to be flush with the alignment mark 605 on the surface of the pressure plate 603, one end of the spring 609, which is housed in the rotating member 608, abuts against the inner wall of the rotating member 608, and the other end abuts against the locking block 610. This pushes the locking block 610 to slide within the rotating member 608 and causes the locking block 610 to extend and engage with the positioning holes 601 on the X segment support-R1 and X segment support-L2, thereby achieving a secure lock on the X segment support-R1 and X segment support-L2 and preventing the display screen from deforming or leaking light during testing.
