Description

Technical Field

[0001] This application relates to the field of automated equipment technology, and in particular to a testing mechanism and aging equipment. Background Technology

[0002] In actual use, industrial products are subject to aging caused by environmental factors such as temperature and light. Therefore, aging testing is an important part of product quality inspection. It uses testing equipment to simulate various factors encountered by the product in real-world usage scenarios to test its aging condition. For example, in the field of display panel testing, the display panel is typically lit up in an aging test chamber for lamp aging testing, and the output and disconnection of the lamp signal are achieved by switching the high and low levels of the electrical components using a power switch.

[0003] To simulate the movement of display panels in real-world usage environments, multiple display panels to be tested are typically fixed to a rotating bracket. However, during the rotation of the display panels, it is impossible to power them on, resulting in the inability to synchronize the rotation and power-on operations. Utility Model Content

[0004] Therefore, it is necessary to provide a testing mechanism and aging equipment to address the problem that the rotation and power-on operation of the display panel cannot be performed simultaneously during the aging test of the display panel.

[0005] A testing organization, the testing organization comprising:

[0006] Rotating bracket;

[0007] At least one carrier and at least one test module are provided, both of which are mounted on the rotating support. The carrier is used to carry the product under test, and when the product under test is carried in the carrier, the test module is communicatively connected to the product under test.

[0008] The conductive module and the power supply module are electrically connected to both the test module and the power supply module, and the conductive module can rotate synchronously with the rotating bracket.

[0009] In one embodiment, the conductive module includes a rotor and a stator that cooperates with the rotor. The rotor is fixed to the rotating bracket and electrically connected to the test module. The stator is electrically connected to the power supply module and is stationary relative to the power supply module.

[0010] In one embodiment, the conductive module further includes a fixing bracket for fixing the rotor and connected to the rotating bracket.

[0011] In one embodiment, the conductive module further includes a limiting plate, a column, and a base. One end of the limiting plate is connected to the stator, and the other end is connected to the column. The end of the column away from the limiting plate is fixed to the base.

[0012] In one embodiment, the rotor is connected to the test module via a cable, and the stator is connected to the power supply module via a cable.

[0013] In one embodiment, there are multiple carriers, each of which is detachably mounted on the rotating support, and the multiple carriers are spaced apart along the circumferential direction of the rotating support.

[0014] In one embodiment, there are multiple test modules, and each of the multiple test modules is detachably mounted on the rotating bracket.

[0015] In one embodiment, the testing mechanism further includes a testing platform, the rotating bracket is rotatably mounted on the testing platform, and the conductive module is fixed to the testing platform.

[0016] In one embodiment, the testing mechanism further includes a drive source that is drive-connected to the rotating support.

[0017] An aging device, the aging device comprising:

[0018] The testing organization as described in any of the above technical solutions; and

[0019] A light source, which is disposed on the rotating bracket, is used to emit a light source toward the vehicle.

[0020] The aforementioned testing mechanism and aging equipment place the product under test (DUT) on a carrier, with the test module communicatively connected to the DUT. Since the carrier is mounted on a rotating support, the DUT can rotate with the support to simulate a rotating environment for performance testing. The testing mechanism provided in this application transmits electrical energy from the power supply module to the test module via a conductive module. Because the conductive module rotates synchronously with the rotating support, and the conductive module and test module remain relatively stationary, the power supply cables between them do not experience tangling or knotting during the rotation of the support, enabling simultaneous power supply and rotation testing of the DUT.

[0028] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0030] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0034] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0035] See Figures 1-3 As shown, this application provides a testing mechanism 100, which includes a rotating bracket 110, at least one carrier 120, at least one testing module 130, a conductive module 140, and a power supply module 150. The testing mechanism 100 is used to perform power supply testing on the product under test during rotation, simulating the performance testing of the product under test under actual use conditions to the greatest extent. In this embodiment, for example, the testing mechanism 100 can perform rotational aging tests on the product under test, which can be a display panel for mobile phones, computers, cameras, etc.

[0036] Both the carrier 120 and the test module 130 are mounted on the rotating support 110. The carrier 120 is used to carry the product under test (DUT). If the carrier 120 has a contoured cavity, the DUT can be quickly connected to the carrier 120 by snapping it into the cavity. When the DUT is carried in the carrier 120, the test module 130 communicates with the DUT. If both the test module 130 and the carrier 120 have communication interfaces, when the DUT is placed in the carrier 120, the communication interface of the test module 130 and the communication interface of the DUT are connected via a data cable to achieve communication between the test module 130 and the DUT. The test module 130 can perform operations such as lighting up and transmitting signals to the DUT. Thus, since the carrier 120 is mounted on the rotating support 110, the DUT can rotate with the rotating support 110 to simulate the rotational environment of the DUT for performance testing.

[0037] The conductive module 140 is electrically connected to both the test module 130 and the power supply module 150. For example, the conductive module 140 is connected to both the test module 130 and the power supply module 150 via cables 160. The conductive module 140 transmits power from the power supply module 150 to the test module 130, enabling the test module 130 to power itself. The test module 130 can then perform operations such as lighting up and transmitting signals to the product under test. The conductive module 140 rotates synchronously with the rotating bracket 110. The conductive module 140 and the test module 130 remain relatively stationary. The power supply cable 160 between the conductive module 140 and the test module 130 will not become tangled or knotted during the rotation of the rotating bracket 110, allowing for simultaneous power supply and rotation testing of the product under test.

[0038] In one embodiment, see Figures 1-3As shown, the conductive module 140 includes a rotor 141 and a stator 142, which cooperate with each other, such as the rotor 141 being rotatably embedded in the stator 142. The rotor 141 is fixed to the rotating bracket 110 and is electrically connected to the test module 130, such as the rotor 141 being connected to the test module 130 via a cable 160. The stator 142 is electrically connected to the power supply module 150, such as the stator 142 being connected to the power supply module 150 via a cable 160. The stator 142 is stationary relative to the power supply module 150. For example, the power supply module 150 is a power supply, which is external to the rotating bracket 110. Since the stator 142 cannot rotate, the stator 142 can be stationary relative to the power supply module 150. In this way, the power supply module 150 can transmit electrical energy to the stator 142 via the cable 160. Since the stator 142 transmits electrical energy to the test module 130 via the rotor 141 and the cable 160, the power supply module 150 can supply power to the test module 130. Furthermore, since the rotor 141 is fixed to the rotating bracket 110, when the rotating bracket 110 rotates, both the rotor 141 and the test module 130 rotate with the rotating bracket 110. The rotor 141 and the test module 130 remain relatively stationary during the power supply process, and the cable 160 between the conductive module 140 and the test module 130 will not experience tangling, knotting, or other adverse phenomena during the rotation of the rotating bracket 110.

[0039] Specifically, see Figures 1-3 As shown, the conductive module 140 also includes a fixing bracket 143. The fixing bracket 143 is used to fix the rotor 141 and is connected to the rotating bracket 110. For example, the fixing bracket 143 can be detachably connected to the rotating bracket 110 via bolts (such as bolts, screws, etc.), and the rotor 141 is connected to the fixing bracket 143. The conductive module 140 can be connected to the rotating bracket 110 via the fixing bracket 143, so that the rotor 141 can rotate accordingly during the rotation of the rotating bracket 110. Furthermore, a connector 1431 is provided at the connection between the rotor 141 and the fixing bracket 143. The connector 1431 is preferably a linear bearing. On the one hand, the connector 1431 can improve the rotational accuracy of the rotor 141 during rotation; on the other hand, the connector 1431 can reduce the wear of the rotor 141 during rotation, thereby increasing the service life of the conductive module 140.

[0040] Further, see Figures 1-3As shown, the conductive module 140 also includes a limiting plate 144, a column 145, and a base 146. One end of the limiting plate 144 is connected to the stator 142, and the other end of the limiting plate 144 is connected to the column 145. The end of the column 145 away from the limiting plate 144 is fixed to the base 146, such as by means of fasteners 147 for locking, snap-fitting, or other methods. In this way, after the base 146 is fixed, the stator 142 will not rotate with the rotating bracket 110, and since the rotor 141 is rotatably embedded in the stator 142, the stator 142 will not interfere with the rotation of the rotor 141.

[0041] In one embodiment, see Figure 1 As shown, there are multiple carriers 120, all of which are detachably mounted on the rotating bracket 110. For example, the multiple carriers 120 are detachably mounted on the rotating bracket 110 via screws, snap-fit ​​connections, or other methods. This allows the original carriers 120 to be removed from the rotating bracket 110 and replaced with new carriers 120 after changes in the specifications and dimensions of the product under test. This adapts to load testing of products with different specifications, expanding the application scenarios of the testing mechanism 100. Furthermore, multiple carriers 120 can simultaneously perform rotational power supply operations on multiple products under test, improving the testing efficiency.

[0042] Furthermore, multiple carriers 120 are spaced apart along the circumferential direction of the rotating support 110. For example, if there are four carriers 120, the angle between the line connecting two adjacent carriers 120 and the rotation axis of the rotating support 110 is 90°; if there are six carriers 120, the angle between two adjacent carriers 120 and the rotation axis of the rotating support 110 is 60°; and if there are eight carriers 120, the angle between two adjacent carriers 120 and the rotation axis of the rotating support 110 is 45°. This application does not limit the specific number of carriers 120; it can be adaptively set according to the number of products to be tested simultaneously for performance testing. The arrangement of multiple carriers 120 can be adaptively set according to the above method, and will not be elaborated further here.

[0043] The aforementioned testing mechanism 100, with multiple carriers 120 spaced apart along the circumferential direction of the rotating support 110, allows for a reasonable arrangement of the carriers 120. There is sufficient operating space between adjacent carriers 120, facilitating the loading and testing of the product under test. Furthermore, when the product under test is subjected to light aging, the uniformity of light source illumination can be ensured, thereby improving the reliability of the light aging test results of the product under test.

[0044] In one embodiment, see Figure 1As shown, there are multiple test modules 130, all of which are detachably mounted on the rotating bracket 110. For example, the multiple test modules 130 are detachably mounted on the rotating bracket 110 via screws, snap-fit ​​connections, or other methods. When testing products under test with different numbers and specifications of communication interfaces is required, the original test modules 130 can be removed from the rotating bracket 110, and the replaced test modules 130 can be reconnected to the rotating bracket 110 to accommodate performance testing of products under test with different numbers and specifications of communication interfaces, further expanding the application scenarios of the testing mechanism 100.

[0045] For example, if the test module 130 has four communication interfaces and each product under test has one communication interface, then the test module 130 can communicate with four products under test simultaneously. If performance testing is required for four products under test, one test module 130 needs to be set on the rotating bracket 110 to perform performance testing on all four products simultaneously. If performance testing is required for eight products under test, two test modules 130 need to be set on the rotating bracket 110 to perform performance testing on all eight products simultaneously. The specific number of test modules 130 is not limited in this application and can be adaptively set according to the number of communication interfaces of the test module 130 and the number of communication interfaces of the products under test, which will not be elaborated further here.

[0046] In one embodiment, see Figures 1-3 As shown, the testing mechanism 100 also includes a testing platform 170. A rotating bracket 110 is rotatably mounted on the testing platform 170 to achieve installation and fixation of the rotating bracket 110. A conductive module 140 is fixed to the testing platform 170. For example, a rotor 141 is fixed to the rotating bracket 110, and a base 146 is fixed to the testing platform 170 by screws, snap-fits, or other means. The testing platform 170 can achieve installation and fixation of the conductive module 140 without interfering with the rotation of the rotor 141.

[0047] Further, see Figure 1 As shown, the test mechanism 100 also includes a drive source (not shown), which is connected to the rotating bracket 110 via a transmission connection. For example, the rotating bracket 110 has a connecting shaft 111, which is connected to the output end of the drive source by means of insertion, sleeve, or other means. The drive source can output power to the connecting shaft 111 to drive the rotating bracket 110 to rotate, simulating the rotational environment of the product under test to perform performance testing.

[0048] To ensure reliable connection between the drive source and the rotating bracket 110, a spline hole can be provided on the connecting shaft 111 so that the output end of the drive source can be engaged with the connecting shaft 111 when the drive source is connected to the connecting shaft 111. Furthermore, in this application, the drive source can be a drive motor, drive cylinder, or other component capable of outputting power; this application does not limit the specific type of component of the drive source.

[0049] Additionally, see Figure 1 As shown, this application also provides an aging device 200, which includes a testing mechanism 100 as described above and a light source 210. The light source 210 is disposed on a rotating bracket 110 and is used to emit light towards a carrier 120. For example, the light source 210 may be a lamp tube, and it is positioned at the rotation axis of the rotating bracket 110 to ensure the uniformity of the light emitted by the light source 210 towards the carrier 120 during the rotation of the rotating bracket 110, thereby improving the uniformity of the light aging test of the product under test carried in the carrier 120. After the product under test is carried in the carrier 120, the light source 210 can emit natural light, especially ultraviolet light, towards the carrier 120 to evaluate the aging performance of the product under test during use, thereby understanding the weather resistance, durability, and other properties of the product under test.

[0050] The aforementioned aging equipment 200 can simulate a light environment to evaluate the aging performance of the product under test during use. It also transmits electrical energy from the power supply module 150 to the test module 130 through the conductive module 140. Since the conductive module 140 can rotate synchronously with the rotating bracket 110, and the conductive module 140 and the test module 130 are relatively stationary, the power supply cable 160 between the conductive module 140 and the test module 130 will not experience tangling, knotting, or other adverse phenomena during the rotation of the rotating bracket 110. The aging equipment 200 can simultaneously perform power supply and rotation aging tests on the product under test.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
