Detailed Implementation

[0048] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0049] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0050] Referring to Figures 1 and 2, this embodiment of the present invention provides a three-dimensional attitude adjustment device, which includes a base 1, a platform 3, and an adjustment assembly 2. The base 1 has a reference surface. The platform 3 is spaced above the base 1 and has a fixing part 31 for fixing the object to be tested. The adjustment assembly 2 includes a plurality of adjustment members 21 that can independently extend and retract in length, and one end of the adjustment member 21 is connected to the reference surface, and the other end is connected to the platform 3. The plurality of adjustment members 21 can extend and retract in length in conjunction to adjust the three-dimensional attitude of the fixing part 31 in the platform 3 relative to the reference surface.

[0051] The three-dimensional posture adjustment device provided in this embodiment of the utility model can be specifically applied to the detection posture adjustment of curved display screens, but is not limited to this application. The usage process will be described using this as an example.

[0052] In practical use, the curved display screen to be tested is first fixed in the platform 3 by the fixing part 31. Then, by controlling and adjusting the actual extension length of each adjusting part 21, the fixing part 31 and the curved display screen can be adjusted in three dimensions relative to the reference plane of the base 1 (e.g., tilting to the left, tilting to the right, tilting forward, tilting backward, etc.). For example, the curved display screen can be photographed and detected from different angles by a CCD camera, so as to accurately and efficiently detect the quality of various parts of the curved display screen.

[0053] Compared with the existing technology of using a three-axis arm to grasp a curved display screen for photo inspection, the three-dimensional posture adjustment device provided in this embodiment of the utility model can quickly adjust the three-dimensional posture of the fixed part 31 in the platform 3 by linking and controlling the actual extension and retraction length of each adjustment component 21 in the adjustment component 2. Thus, the beneficial effect of photo inspection of the posture of the object to be inspected in various directions can be achieved with a small adjustment range, a short adjustment time, and high efficiency and accuracy.

[0054] In one embodiment, the adjustment component 2 includes six adjustment members 21; and the six adjustment members 21 are arranged in a circular array about the center of the reference plane.

[0055] Specifically, as explained in further detail with reference to Figures 1 and 2, six adjustment components 21 are specifically set in the adjustment component 2, and the six adjustment components 21 are arranged in a circular array about the center of the reference plane of the base 1. In this way, by controlling the actual extension and retraction length of the six adjustment components 21 in a linkage manner, more three-dimensional postures of the fixed part 31 in the platform component 3 can be achieved (e.g., tilting to the left front side, tilting to the right front side, tilting to the left rear side, tilting to the right rear side, etc.), thereby achieving the beneficial effect of taking pictures and detecting the postures of the part to be inspected from more directions.

[0056] Of course, other numbers of adjustment components 21 can also be set in the above-mentioned adjustment component 2, such as four, five, seven, etc., and the relative positions between each adjustment component 21 can also be flexibly set according to the actual use scenario.

[0057] In one embodiment, the adjusting member 21 includes a first shaft segment 211, a second shaft segment 212, and a driving block 213; the first shaft segment 211 and the second shaft segment 212 are concentrically and telescopically connected along the axial direction; the driving block 213 is connected to the first shaft segment 211 or the second shaft segment 212 and is used to drive the first shaft segment 211 to telescopically move toward or away from the second shaft segment 212.

[0058] Specifically, as further explained in conjunction with Figures 1 and 4, the adjusting component 21 is specifically configured to be concentrically and telescopically connected to the first shaft segment 211 and the second shaft segment 212 along one axis, and is connected to the first shaft segment 211 or the second shaft segment 212 through the driving block 213. The driving block 213 can be, but is not limited to, a hydraulic drive module, a stepper motor drive module, etc., and can realize the function of driving the first shaft segment 211 to move toward or away from the second shaft segment 212 in a quantitative telescopic movement.

[0059] Furthermore, the adjustment components 21 in the adjustment assembly 2 can be uniformly connected to a controller, which can then be used to control the actual driving amplitude of the drive blocks 213 of multiple adjustment components 21 in a coordinated manner, thereby achieving the beneficial effect of coordinated control of the actual extension and retraction length of each adjustment component 21.

[0060] The specific arrangement of the aforementioned adjustment component 21 has the advantages of simple structure and flexible control over its own extension and retraction length.

[0061] In one embodiment, a first hinge assembly 11 is provided in the reference plane; one end of the adjusting member 21 is movably hinged to the first hinge assembly 11; the first hinge assembly 11 is capable of causing one end of the adjusting member 21 to rotate in at least two different directions.

[0062] Specifically, as further explained in conjunction with Figures 1 and 3, a first hinge assembly 11 is provided in the reference plane of the base 1. The first hinge assembly 11 can also be arranged in a circular array about the center of the reference plane. Moreover, one end of the adjusting member 21 is movably hinged to the first hinge assembly 11, and the first hinge assembly 11 can cause at least two rotations in different directions at one end of the adjusting member 21. In this way, when the adjusting member 21 itself undergoes length extension and retraction adjustment, the first hinge assembly 11 can rotate accordingly under the deformation of the adjusting member 21, ensuring that one end of the adjusting member 21 will not experience motion interference during the extension and retraction process.

[0063] In one embodiment, the first hinge assembly 11 includes a first hinge seat 111 and a first hinge head 112; the first hinge seat 111 is embedded in a reference surface and has a first hinge axis extending in a first direction; the first hinge head 112 is hinged to the first hinge seat 111 via the first hinge axis and has a second hinge axis extending in a second direction; wherein the second hinge axis can be hinged to one end of the adjusting member 21; the first direction and the second direction are two intersecting directions.

[0064] Specifically, referring to Figure 3 for further detailed explanation, the first hinge assembly 11 is specifically configured to include a first hinge seat 111 and a first hinge head 112. The first hinge seat 111 can be flush-mounted onto the reference surface, and the first hinge head 112 can be hinged to the first hinge seat 111 via a first hinge shaft. In this way, the first hinge head 112 can rotate around a first direction via the first hinge shaft. The first hinge head 112 can be hinged to one end of the adjusting member 21 via a second hinge shaft, so that the adjusting member 21 can rotate around a second direction via the second hinge shaft. The first direction and the second direction can be set as two mutually perpendicular intersecting directions. In this way, the first hinge assembly 11 can enable one end of the adjusting member 21 to swing omnidirectionally relative to the reference surface, thereby fully ensuring the rotational freedom of one end of the adjusting member 21.

[0065] In one embodiment, a second hinge assembly 32 is provided on the side of the platform member 3 facing the base 1; the other end of the adjusting member 21 is movably hinged to the second hinge assembly 32; the second hinge assembly 32 is capable of causing the other end of the adjusting member 21 to rotate in at least two different directions.

[0066] Specifically, as further explained in conjunction with Figures 1 and 5, a second hinge assembly 32 is provided on the side of the platform 3 facing the base 1. The second hinge assembly 32 can also be arranged in a circular array about the center of the platform 3. Moreover, the other end of the adjusting member 21 is movably hinged to the second hinge assembly 32, and the second hinge assembly 32 can cause the other end of the adjusting member 21 to rotate in at least two different directions. In this way, when the adjusting member 21 itself undergoes length extension and retraction adjustment, the second hinge assembly 32 can rotate accordingly under the deformation of the adjusting member 21, ensuring that the other end of the adjusting member 21 will not experience motion interference during the extension and retraction process.

[0067] In one embodiment, the second hinge assembly 32 includes a second hinge seat 321 and a second hinge head 322; the second hinge seat 321 is embedded in the platform member 3 and has a third hinge axis extending in a third direction; the second hinge head 322 is hinged to the second hinge seat 321 through the third hinge axis and has a fourth hinge axis extending in a fourth direction; wherein the fourth hinge axis can be hinged to the other end of the adjusting member 21; the third direction and the fourth direction are two intersecting directions.

[0068] Specifically, referring to Figure 5 for further detailed explanation, the second hinge assembly 32 is specifically configured to include a second hinge seat 321 and a second hinge head 322. The second hinge seat 321 can be flush-mounted into the platform 3. The second hinge head 322 can be hinged to the second hinge seat 321 via a third hinge axis. In this way, the second hinge head 322 can rotate around a third direction via the third hinge axis. The second hinge head 322 can be hinged to the other end of the adjusting member 21 via a fourth hinge axis. In this way, the adjusting member 21 can rotate around a fourth direction via the fourth hinge axis. The third direction and the fourth direction can also be set as two mutually perpendicular intersecting directions. In this way, the second hinge assembly 32 can make the other end of the adjusting member 21 swing omnidirectionally relative to the platform 3, thereby fully ensuring the rotational freedom of the other end of the adjusting member 21.

[0069] In one embodiment, the fixing part 31 includes an adsorption member; the adsorption member is disposed on the side of the stage 3 opposite to the base 1, and is specifically used to provide a suction pipe for adsorption negative pressure.

[0070] Specifically, referring to Figure 5 for further details, the fixing part 31 is specifically configured as an adsorption element and a suction pipe connected to the adsorption element under negative pressure. When the suction pipe generates negative pressure on the adsorption element, the adsorption element can correspondingly adsorb and fix the curved display screen onto the carrier 3 under air pressure, thus achieving the fixation of the curved display screen. Furthermore, when it is necessary to release the curved display screen, the suction pipe only needs to stop the negative pressure suction; at this time, the adsorption element loses its adsorption and fixing force on the curved display screen, and the curved display screen can be automatically released.

[0071] The specific arrangement of the fixing part 31 described above has the advantages of simple structure, non-clamping fixing of the workpiece to be tested, and automatic release.

[0072] In one embodiment, the platform 3 and the base 1 are respectively provided with clearance holes for laying suction pipes.

[0073] Specifically, as explained in further detail with reference to Figure 5, clearance holes for laying suction pipes are respectively provided in the platform 3 and the base 1. In this way, the suction pipes in the fixing part 31 can be laid from top to bottom through the clearance holes. On the one hand, this makes the structure of the three-dimensional attitude adjustment device more compact, and on the other hand, it can avoid the problem of suction pipes getting tangled together due to attitude adjustment changes of the platform 3.

[0074] In addition, this utility model embodiment also provides a detection device, which includes the above-mentioned three-dimensional posture adjustment device and detection camera; wherein, the detection camera is arranged at intervals above the stage member 3, and is used to take pictures of the object to be detected in the fixed part 31.

[0075] This testing equipment can be used, but is not limited to, for testing parts such as curved display screens. In specific testing applications, the part to be tested can be installed and fixed through the fixing part 31 in the three-dimensional posture adjustment device. Then, the extension and retraction lengths of multiple adjustment parts 21 are controlled in a coordinated manner to adjust the three-dimensional posture of the fixing part 31 and the part to be tested relative to the reference surface. Moreover, the testing camera can take pictures of the part to be tested in the fixing part 31. By comparing the image information captured by the testing camera with the standard reference image, the testing of the part to be tested can be completed.

[0076] The testing equipment includes the aforementioned three-dimensional attitude adjustment device, which can achieve all the beneficial effects of the aforementioned three-dimensional attitude adjustment device, and will not be described in detail here.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
