[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] In order to automatically adjust the camera position during the LCD screen testing process, this application provides a camera adjustment component and an LCD screen testing device, which will be described below with reference to the accompanying drawings.

[0026] For example, please refer to Figure 1 As shown, Figure 1 This is a schematic diagram of a camera adjustment assembly provided in an embodiment of this application. The camera adjustment assembly 100 is applied to an LCD screen testing device, which includes a camera. The camera is used to test LCD screens, such as those involved in the manufacturing process or those returned for repair. For example, the camera can take pictures of the solid color image displayed on the LCD screen to identify bright spots, dark spots, or dead pixels. The camera adjustment assembly 100 is used to support the camera and can adjust the position of the camera. Thus, when the LCD screen is fixed in a specific position during testing, the position of the camera can be adjusted to test different positions of the LCD screen; the position of the camera can also be adjusted to adapt to the testing of LCD screens of different sizes.

[0027] The camera adjustment assembly 100 includes a first adjustment group 110, a second adjustment group 120, a third adjustment group 130, and corresponding connecting or supporting mechanism brackets 181 and crossbeams 182.

[0028] The bracket 181 is used to support the camera, and the crossbeam 182 is used to fix and support the first adjustment group 110. The first adjustment group 110, the second adjustment group 120, and the third adjustment group 130 are used to adjust the position of the camera from the first direction X, the second direction Y, and the third direction Z, respectively. The first direction X, the second direction Y, and the third direction Z are all perpendicular to each other; for example, the first direction X can be left-right, the second direction Y can be up-down, and the third direction Z can be front-back. Of course, the above-mentioned directional settings are for ease of description and should not be construed as limitations on the camera adjustment assembly 100.

[0029] For example, the first adjustment group 110 is slidably connected to the bracket 181. The first adjustment group 110 is used to drive the bracket 181 to move along the first direction X under the action of the first driving signal. For example, the first adjustment group 110 can adjust the left and right movement of the camera, thereby changing the left and right position of the camera relative to the LCD screen. Furthermore, the first adjustment group 110 may include an electrical signal driving component, so that when the first driving signal is given, the driving component can drive the actuator to move the camera, realizing intelligent automatic adjustment of the camera's position in the first direction X, that is, the left and right direction.

[0030] The crossbeam 182 is fixedly connected to the first adjustment group 110, so that the first adjustment group 110 and the bracket 181 can be adjusted in position as a whole with the crossbeam 182.

[0031] For example, the second adjustment group 120 is slidably connected to the crossbeam 182. The second adjustment group 120 is used to move the entire assembly consisting of the crossbeam 182, the bracket 181, and the camera along the second direction Y under the influence of the second drive signal. For example, the second adjustment group 120 can adjust the vertical movement of the camera, thereby changing the vertical position of the camera relative to the LCD screen. The second adjustment group 120 may include an electrical signal drive component, so that when the second drive signal is given, the drive component can drive the actuator to move the camera, realizing intelligent automatic adjustment of the camera's position in the second direction Y, i.e., the vertical direction.

[0032] For example, the third adjustment group 130 is fixedly connected to the bracket 181, so that the third adjustment group 130 can move along with the movement of the bracket 181. The third adjustment group 130 is slidably connected to the camera, and the third adjustment group 130 is used to drive the camera to move along a third direction Z under the action of a third drive signal. For example, the third adjustment group 130 can adjust the camera's forward and backward movement, thereby changing the camera's forward and backward position relative to the LCD screen. The third adjustment group 130 may include an electrical signal drive element, so that when a third drive signal is given, the drive element can drive the actuator to move the camera, realizing intelligent automatic adjustment of the camera's position in the third direction Z, that is, the forward and backward direction.

[0033] It should be noted that the camera's position adjustment in the three directions can be understood as follows: when the camera needs to be adjusted in the third direction Z (forward / backward), a third drive signal is given to cause the third adjustment group 130 to move the camera along the third direction Z; when the camera needs to be adjusted in the first direction X (left / right), a first drive signal is given to cause the first adjustment group 110 to move the entire assembly of the third adjustment group 130 and the camera along the first direction X; when the camera needs to be adjusted in the second direction Y (up / down), a second drive signal is given to cause the second adjustment group 120 to move the entire assembly of the first adjustment group 110, the third adjustment group 130, and the camera along the second direction Y. Of course, position adjustments in the first direction X, the second direction Y, and the third direction Z can also be performed simultaneously, thereby increasing the speed of camera position adjustment.

[0034] It should be noted that since the third adjustment group 130 adjusts the front-to-back position of the camera relative to the LCD screen, and generally, when the camera adjustment assembly 100 is fixed to the base, the front-to-back position of the camera relative to the LCD screen is not significantly different, the third adjustment travel of the third adjustment group 130 to the camera can be set to be less than the first adjustment travel of the first adjustment group 110 to the camera, or less than the second adjustment travel of the second adjustment group 120 to the camera. No specific limitations are placed on the magnitude of the first and second adjustment travels.

[0035] In the camera adjustment component 100 provided in this application embodiment, the camera position is adjusted in three mutually perpendicular directions by setting a first adjustment group 110, a second adjustment group 120 and a third adjustment group 130 respectively. The adjustment can be performed automatically by the machine without manual intervention. It can adapt to testing different positions of the LCD screen and can adapt to different LCD screens, saving testing equipment and costs, and can speed up the testing process to improve the production efficiency of the LCD screen.

[0036] For example, please refer to Figure 2 and Figure 3 As shown, Figure 2 This is another schematic diagram of the camera adjustment component provided in the embodiments of this application. Figure 3 for Figure 2 The diagram shows a partial structure of the camera adjustment assembly. The first adjustment group 110 includes a first actuator 112, a second actuator 114, and a first drive element.

[0037] The first actuator 112 is fixedly connected to the bracket 181. The second actuator 114 is fixedly connected to the crossbeam 182, and the second actuator 114 is slidably connected to the first actuator. For example, the first actuator 112 can be a gear, and the second actuator 114 can be a rack, which can be arranged in a circular pattern. This circular arrangement can increase the length of the rack within a limited space, thereby meeting the first adjustment stroke requirement of the first adjustment group 110. Alternatively, the first actuator 112 and the second actuator 114 can be a combination of a slider and a groove. Yet another example is that the first actuator 112 and the second actuator 114 can be a combination of an elastic element and a fixed element, where the position of the camera along the first direction X is changed by the deformation of the elastic element.

[0038] For example, the first driving member is fixedly connected to the first actuator 112. The first driving member is used to drive the first actuator 112 to slide relative to the second actuator 114 along the first direction X under the action of the first driving signal, and to drive the camera to move along the first direction X. The first driving member is, for example, a motor, which receives the first driving signal from the control board in the LCD screen testing device and operates accordingly.

[0039] For example, please refer to Figure 2 And see Figure 4 As shown, Figure 4 for Figure 2 The diagram shows a partial structure of B in the camera adjustment assembly. The second adjustment group 120 includes a third actuator 122, a fourth actuator 124, and a second drive element.

[0040] The third actuator 122 is fixedly connected to the crossbeam 182. The fourth actuator 124 is slidably connected to the third actuator 122. For example, the third actuator 122 can be a gear, and the fourth actuator 124 can be a rack, which can be arranged in a circular pattern. This circular arrangement can increase the length of the rack within a limited space, thereby meeting the second adjustment stroke requirement of the second adjustment group 120. Alternatively, the third actuator 122 and the fourth actuator 124 can be a combination of a slider and a groove. Yet another example is that the third actuator 122 and the fourth actuator 124 can be a combination of an elastic element and a fixed element, where the position of the camera along the second direction Y is changed by the deformation of the elastic element.

[0041] For example, the second driving member is fixedly connected to the third actuator 122. The second driving member is used to drive the third actuator 122 to slide relative to the fourth actuator 124 along the second direction Y under the action of the second driving signal, and to drive the camera to move along the second direction Y. The second driving member is, for example, a motor, which is activated by receiving a first driving signal from the control board in the LCD screen testing device.

[0042] It should be noted that when the LCD screen testing device has at least two cameras, the at least two camera adjustment components 100 can share components in structure, thereby reducing the number of components and saving costs.

[0043] Taking a liquid crystal display (LCD) testing device with two cameras as an example, the two camera adjustment components 100 can share a second adjustment group 120. That is, two first adjustment groups 110 are set on the crossbeam 182, and the two first adjustment groups 110 can share a first driving component. They also use the same second adjustment group 120 to move the two first adjustment groups 110 and the two cameras in the second direction Y. To ensure the system stability and reliability of the LCD testing device, two sets of slider groups can be set. These two sets of slider groups can be set on both sides of the second adjustment group 120 along the first direction X, thereby balancing the two first adjustment groups 110 and the two cameras on the crossbeam 182.

[0044] For example, please refer to Figure 2 And see Figure 5 As shown, Figure 5 for Figure 2 The diagram shows a partial structure of C in the camera adjustment assembly. The third adjustment group 130 includes a first sliding part 132, a second sliding part 134, and a third driving member.

[0045] The first sliding part 132 is fixedly connected to the bracket 181. The second sliding part 134 is fixedly connected to the camera and is slidably connected to the first sliding part 132. For example, one of the first sliding part 132 and the second sliding part 134 may be provided with a sliding groove and the other with a protruding slider, and the two are slidably connected to achieve the sliding connection between the first sliding part 132 and the second sliding part 134.

[0046] The third driving member is connected to the second sliding part 134. The third driving member is used to drive the second sliding part 134 to slide relative to the first sliding part 132 under the action of the third driving signal, and to drive the camera to move along the third direction Z. The third driving member is, for example, a motor, which receives the third driving signal from the control board in the LCD screen testing device and operates accordingly.

[0047] To achieve greater freedom of adjustment for the camera, this application embodiment also includes a mechanism for adjusting the camera's rotation direction. For example, please refer to... Figure 6 As shown, Figure 6This is another schematic diagram of the camera adjustment assembly provided in an embodiment of this application. The camera adjustment assembly 100 further includes a fourth adjustment group 140, a fifth adjustment group 150, and a sixth adjustment group 160. The fourth adjustment group 140, the fifth adjustment group 150, and the sixth adjustment group 160 are used to adjust the position of the camera relative to the liquid crystal screen by rotating around a first axis, a second axis, and a third axis. The first axis, the second axis, and the third axis are mutually perpendicular, thereby enabling six degrees of freedom position adjustment of the camera. The first axis, the second axis, and the third axis are defined for ease of explanation and may not actually exist, and should not be construed as a limitation on the camera adjustment assembly 100.

[0048] For example, the fourth adjustment group 140 is connected to the camera and is used to drive the camera to rotate around the first axis under the action of the fourth drive signal. For example, the fourth adjustment group 140 includes a first bushing 142, a first rotating shaft 144, and a fourth drive member.

[0049] The first bushing 142 has a shaft hole. The first rotating shaft 144 is fixed to the camera, for example, by means of a connecting structure, so that when the first rotating shaft 144 rotates relative to the first bushing 142, it can drive the camera to rotate. To control the rotation accuracy, gears and toothed grooves can also be provided on the first bushing 142 and the first rotating shaft 144, and the rotation accuracy can be controlled by the meshing of the gears and toothed grooves.

[0050] The first bushing 142 can be fixedly connected to the second sliding part 134 of the third adjustment group 130, thereby allowing for a reasonable arrangement of the device's placement and improving space utilization.

[0051] For example, the fourth driving component is connected to the first rotating shaft 144. The fourth driving component 6 is used to drive the first rotating shaft 144 to rotate around the first axis under the action of the fourth driving signal, and to drive the camera to rotate around the first axis. The fourth driving component can be a motor, and the rotating shaft of the motor is fixedly connected to the first rotating shaft 144. The motor receives the fourth driving signal from the control board in the LCD screen testing device and then operates.

[0052] For example, please refer to Figure 6 And see Figure 7 As shown, Figure 7 for Figure 2 The diagram shows a partial structural diagram of the camera adjustment assembly, specifically section D. The fifth adjustment group 150 is connected to the camera and is used to drive the camera to rotate around the second axis under the action of a fifth drive signal. For example, the fifth adjustment group 150 includes a first connecting member 152, a sliding member 154, and a fifth drive member.

[0053] The first connecting member 152 is fixedly connected to the first rotating shaft 144. The first connecting member 152 is provided with at least one sliding groove, which may be arc-shaped to accommodate the rotation direction of the camera. The sliding member 154 is fixedly connected to the camera, so that the sliding member 154 can drive the camera to rotate when it slides. The sliding member 154 is slidably connected in at least one sliding groove of the first connecting member 152. The sliding member 154 may be provided with at least one column, and the number of columns corresponds to the number of sliding grooves. With multiple columns and multiple sliding grooves, it is easier to set the camera rotation stroke compared to a single column and a single sliding groove.

[0054] The fifth driving component is connected to the slider 154. Under the action of the fifth driving signal, the fifth driving component drives the slider 154 to rotate around the second axis, thereby rotating the camera. The fifth driving component can be a motor, which receives the fifth driving signal from the control board in the LCD screen testing device and operates accordingly.

[0055] For example, the sixth adjustment group 160 is connected to the camera and is used to drive the camera to rotate around the third axis under the action of the sixth drive signal. For example, the sixth adjustment group 160 includes a first gear 162, a second gear 164 and a sixth drive member.

[0056] The first gear 162 is fixedly connected to the slider 154. The second gear 164 is fixedly connected to the camera, and the second gear 164 meshes with the first gear 162.

[0057] The sixth drive component is connected to the second gear 164. Under the action of the sixth drive signal, the sixth drive component drives the second gear 164 to rotate around the third axis, thereby rotating the camera. The sixth drive component can be a motor, which receives the sixth drive signal from the control board in the LCD screen testing device and operates accordingly.

[0058] The camera adjustment assembly 100 provided in this application embodiment adjusts the camera's position in three mutually perpendicular directions by setting a first adjustment group 110, a second adjustment group 120, and a third adjustment group 130. This adjustment can be performed automatically without manual intervention, adapting to testing different positions of the LCD screen and accommodating different LCD screens. This saves on testing equipment and costs, and accelerates the testing process, thereby improving LCD screen production efficiency. Furthermore, a fourth adjustment group 140, a fifth adjustment group 150, and a sixth adjustment group 160 adjust the camera's rotational position, allowing for more precise and flexible adjustment of the camera's position, improving the testing efficiency of the LCD screen testing device and the user's testing experience.

[0059] This application also provides a liquid crystal display (LCD) testing device, which includes a camera, the aforementioned camera adjustment components, and a control board. The control board sends different drive signals to the camera adjustment components, thereby enabling automated control of the camera adjustment components. The number of cameras and camera adjustment components can be configured accordingly. When there are at least two cameras, multiple camera adjustment components can adaptively share certain components, thereby reducing the number of components and lowering costs, and allowing for a more rational space layout and improved space utilization. The structure and operation of the camera adjustment components are described above and will not be repeated here. The LCD testing device may also include other components such as LCD fixing components, which are not specifically limited here. Since this LCD testing device adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0060] The camera adjustment component and LCD screen testing device provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application, and the descriptions of the embodiments above are only for the purpose of helping to understand this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
