Description

Technical Field

[0001] This invention relates to the field of electronic device manufacturing, and more particularly to an electronic device testing trolley. Background Technology

[0002] Throughout the lifecycle of electronic products, the probability of equipment failure follows a bathtub curve (or failure rate curve), which includes an early failure period. This means that the probability of equipment failure is relatively high in the early stages of product use, reflecting problems in design, manufacturing, and installation. To identify these problems, determine improvement directions, test product lifespan, and help products that have been in use for a longer period avoid the high failure probability in the early stages and enter a more stable phase with a lower failure rate, aging tests are typically performed on all products or their components during the production process. Currently, a more efficient approach is to use test trolleys to transport electronic products in batches to a specific high-temperature aging test chamber for testing. However, current test trolleys require operators to manually plug and unplug power connectors and manage power cords for multiple electronic products, as well as manually push the test trolleys for transport, resulting in high labor intensity. Furthermore, current test trolleys and testing systems cannot monitor the progress of aging tests in real time. For example, the total test time for each electronic product, the time when a product fails, and the time when it is re-energized for testing often require operators to record and manually power on the product when a fault is discovered during inspections, making real-time monitoring impossible.

[0003] Therefore, it is necessary to design a new type of test trolley and transport test system to overcome the above-mentioned defects. Summary of the Invention

[0004] The purpose of this invention is to provide a novel test trolley and transport test system, which can automatically connect electrical connectors and common electrical connectors during loading, reducing the burden on operators and lowering the failure rate.

[0030] To provide a further understanding of the purpose, structure, features, and functions of the present invention, detailed descriptions are provided below with reference to specific embodiments.

[0031] Certain terms are used in the specification and claims to refer to specific elements. It will be understood by those skilled in the art that manufacturers may use different names to refer to the same element. This specification and claims do not distinguish elements by differences in name, but rather by differences in function. The term "comprising" throughout the specification and claims is an open-ended term and should be interpreted as "comprising but not limited to".

[0032] Reference Figures 1 to 4 The diagram shows a first embodiment of the electronic device test trolley of the present invention. The electronic device test trolley 10 includes a frame 11, a base 12, a plurality of partitions 13 and a plurality of electrical connectors 14.

[0033] The base 12 is fixed to the frame 11. Preferably, the frame 11 is constructed from stainless steel or aluminum profiles to form a frame structure, and its projection onto the horizontal plane is approximately rectangular. The base 12 supports electronic devices placed on it. These electronic devices include, for example, displays, display panels, or a portion of a display panel that is partially finished; the invention is not limited to these, but a display is used as an example below. In this embodiment, the base 12 is generally horizontally positioned. Multiple dividers 13 are fixedly disposed on the base 12 to divide the frame 11 into multiple placement areas, each of which can vertically place a display. Figure 1 As shown, in the xyz coordinate axis, the xy plane is approximately horizontal, the z direction is vertical, and the x and y directions are not parallel; preferably, in this embodiment, the x direction is perpendicular to the y direction, but this invention is not limited thereto. Multiple separators 13 are arranged along the x direction, and each separator 13 extends along a direction in the yz plane. Thus, since the monitor is placed vertically, the display surface is parallel to the extension direction of the separators, or in other words, the display surface is parallel to the yz plane, occupying less space and allowing more monitors to be tested simultaneously; at the same time, the monitors under test are arranged with intervals between them, and during the test, the operator can intuitively and conveniently observe the problems of the test screens of each monitor from an oblique angle. Preferably, the separator 13 may also include a partition 133 to separate adjacent placement areas, preventing the free end of the monitor from tilting and crossing into the adjacent placement area.

[0034] In other embodiments, the base 12 may also be at a slight angle (e.g., no more than 5°) relative to the horizontal direction, so that the base 12 on the feed side is slightly higher, preventing the display mounted on the base 12 from accidentally slipping off the feed side. The feed side is located in the direction in which the multiple separators 13 are arranged (e.g., ...). Figure 1 one side of the x-direction (e.g.) Figure 1 (In the y-direction), the robotic arm moves the display in and out of the placement area on the feeding side, and the operator can also manually move the display in and out of the placement area on the feeding side. Preferably, the frame 11 is also provided with a blocking member on the opposite side of the feeding side to prevent the display carried on the base 12 from accidentally slipping off the opposite side.

[0035] In this embodiment, the separator 13 includes a first shaft 131 disposed along a first direction l. An electrical connector 14 is adjustablely fixed to the first shaft 131 and extends from a first side of the separator 13. The first shaft 131 is parallel to the display surface of the display device, and in the figure, the first shaft 131 is parallel to the yz plane; the first side is approximately perpendicular to the first direction 131. The first shaft 131 can be one, two, or more smooth shafts, and its cross-sectional shape includes, but is not limited to, circles, squares, triangles, etc. Figure 2 and Figure 3 The example is two smooth shafts with circular cross-sections (this invention is not limited thereto). The first shaft 131 can also be a threaded shaft, or a combination of a smooth shaft and a threaded shaft (this invention is not limited thereto).

[0036] In a preferred embodiment, the electrical connector 14 is floating, meaning it can float within a small range in a plane perpendicular to the insertion direction. This reduces the precision requirements for automated alignment and ensures effective electrical connection even with slight misalignment after alignment, without damaging the power connector of the display or the electrical connector 14 in the test carriage 10, thus extending the lifespan of the test carriage 10 components. In another preferred embodiment, the electrical connector 14 can also float within a small range in the insertion direction, thus overcoming damage to the power connector of the display and the electrical connector 14 in the test carriage 10 caused by height differences. Figure 2 and Figure 3 As shown, the electrical connector 14 may include a floating seat 144, which is sleeved on the first shaft 131 and floats connected to the connector portion.

[0037] The electrical connector 14 can be of the flexible probe type. The flexible probe 141 is electrically connected to each pin in the power socket of the display along the insertion direction. It is suitable for situations where the pins in the power socket are arranged side by side, such as when the power socket of the display is an AC three-pin female connector. Preferably, the electrical connector 14 also includes a guide portion 142. The free end 1421 of the guide portion 142 is recessed relative to the bottom 1422 of the guide portion 142. The bottom 1422 of the guide portion 142 has the same cross-sectional size as the power socket of the display. In other words, the bottom 1422 of the guide portion 142 has the same size as the corresponding plug of the power socket of the display. This allows the smaller free end 1421 of the guide portion 142 to be inserted into the power socket of the display within a certain offset range, and gradually guides the probe of the electrical connector 14 to accurately align with the pins in the power socket of the display. The shape of the bottom 1422 of the guide portion 142 may be the same as or different from the shape of the corresponding position of the plug of the power socket of the display, but at least some of its edges or corners coincide with the edge of the corresponding position of the plug of the power socket of the display. The mating is completed when the free end of the guide portion 142 abuts against the inside of the power socket of the display, or when the outer extension of the electrical connector 14 abuts against the display housing outside the power socket of the display.

[0038] Preferably, the electrical connector 14 also includes a standard power socket 145 for introducing power to the electrical connector 14 via a universal power cord and for powering the display to which the electrical connector 14 is connected. The standard power socket 145 may be the same as or different from the power socket of the display.

[0039] In another embodiment, the electrical connector 14 can also directly use a standard plug that matches the power socket of the display. In this case, the electrical connector 14 can directly attach the cable containing the standard plug to the floating part of the floating structure. Alternatively, the electrical connector 14 can use an adapter for a first standard plug and a second standard socket, with the adapter fixed to the floating part of the floating structure, and power introduced to the electrical connector 14 via a power cord with a corresponding second standard plug. The first standard and the second standard can be the same or different.

[0040] For cases where the power connector is inserted parallel to the display surface of the monitor, and the display surface extends vertically:

[0041] In one embodiment, such as Figure 1 As shown, the first direction l is parallel to the base 12, and the insertion direction of the electrical connector 14 is perpendicular to the base 12 (e.g., Figure 1 (in the z-direction). When the monitor is placed vertically, its power connector is inserted in the vertical direction, or in other words, the power connector is inserted in the direction shown in the image. Figure 1The z-direction is opposite to the insertion direction of the electrical connector 14. The display is moved to the space above a placement area formed by the partition 13, and the power socket of the display is vertically aligned with the corresponding electrical connector 14. The display is then moved downwards, so that the display is vertically placed on the base 12 in the placement area after being electrically connected to the electrical connector 14.

[0042] In another embodiment, the first direction l is perpendicular to the base 12 (or along) Figure 1 (in the z direction), at this time, the insertion direction of the electrical connector 14 is parallel to the base 12, and the electrical connector 14 is located on the opposite side of the feed side. When the display is placed vertically, the insertion direction of its power socket is parallel to the base 12; alternatively, the display with the power socket insertion direction perpendicular to the base 12 can be rotated vertically, while the display surface orientation remains unchanged, thereby achieving that the insertion direction of the power socket is parallel to the base 12 when the display is placed vertically. The display is transported to the base 12 of a placement area formed by the separator 13, and the display is moved horizontally so that the power socket of the display is aligned with the corresponding electrical connector 14 and inserted to achieve electrical connection.

[0043] For cases where the power connector is inserted perpendicular to the display surface of the monitor, and the display surface extends vertically:

[0044] The first direction l is parallel to the base 12, and at this time the insertion direction of the electrical connector 14 is parallel to the base 12 (e.g., Figure 1 (x-direction in the image). Move the display onto the base 12 of a placement area formed by the partition 13, and move the display horizontally in a direction perpendicular to the display surface (e.g., in the x-direction). Figure 1 (in the x direction) so that the power socket of the display is aligned with the corresponding electrical connector 14 and inserted to achieve electrical connection.

[0045] In one embodiment, when the display is transported to a position where it is electrically connected to an electrical connector 14 and placed vertically on a base 12, the display also abuts against the first side of the corresponding partition 13, or in other words, the back cover of the display abuts against the first side of the partition 13 corresponding to the electrical connector 14 to which it is electrically connected.

[0046] Preferably, the outer surface corners of the separator 13 are rounded or rounded. Preferably, a flexible element (not shown in the figure) is attached to the outer surface of the separator 13. The flexible element is provided at least partially on at least the first side of the separator 13 to avoid scratches, indentations, or other defects on the back cover of the display; alternatively, a flexible element can also be provided at least partially on the second side of the separator 13 opposite to the first side to avoid scratches, indentations, or other defects on the front cover or screen surface of the display. The flexible element can be a flexible film, flexible coating, flexible plate, foam, sponge, etc., and is attached to the separator 13 by plating, attaching, or other means. Preferably, the flexible element can also be independently mounted on the separator 13 or the base. For example, the flexible element can be a flexible brush pad or a flexible sponge pad, extending from the first and second sides of the separator 13 to support or abut against the display in the corresponding placement area. When the display is placed, the flexible brush pad or flexible sponge pad moves or rotates, and its flexible bristles or sponge deform. The flexible member may extend only from the first side of the first side of the separator 13; the flexible member may also be immovable or non-rotatable; the present invention is not limited thereto.

[0047] like Figure 4 and 5 As shown, in this embodiment, the test carriage 10 further includes a common electrical connector 15 for automatically docking with the external power supply connector 41 via magnetic attraction. At least one of the common electrical connector 15 and the external power supply connector 41 can move within a certain range. Preferably, one of them is floating; or, at least one of them can float within a small range in a plane perpendicular to the insertion direction. In another embodiment, one or the other of them can float in the insertion direction. This reduces the accuracy requirements for automated alignment. When the test carriage 10 is pushed or transported to the vicinity of the external power supply connector 41, its common electrical connector 15 can automatically align and electrically connect with the power supply connector 41 via magnetic attraction. The common electrical connector 15 can be disposed on the outer side or bottom surface of the test carriage 10 frame 11. Preferably, the common electrical connector 15 can be disposed on the frame 11 located at... Figure 1 and Figure 4 The lower left or right side in the x-direction; preferably, the common electrical connector 15 can be located on the frame 11. Figure 1 The preferred position is located slightly below the opposite side (or rear side) of the feed side. This preferred position is conducive to the parallel power supply and testing of multiple test carriages 10, and also to the observation and handling of the numerous displays in the test carriage 10 by operators or automatic monitoring equipment during the testing process.

[0048] The common electrical connector 15 in the test trolley 10 can be electrically connected to each electrical connector in the same test trolley directly through a cable, or indirectly through power management chips, hubs and other modules and cables.

[0049] Preferably, the test carriage 10 also includes an automatic power-on module 16 for automatically powering on the displays connected to the electrical connector 14. The automatic power-on module 16 can also control the activation of test modes in the displays to play specific images (e.g., red, green, and blue images, and a mixture of at least two of these three colors) for burn-in testing. The aforementioned test modes in the displays can also be activated by a specific control generator; for example, the universal remote control for the displays can be operated in a certain sequence to generate corresponding coded signaling to instruct the displays to enter test mode. In another embodiment, the test carriage 10 also provides test images to each display via an external signal source; this invention is not limited to this.

[0050] Preferably, the test carriage 10 also includes a power-on detection module 17, used to detect the power-on status of each display electrically connected to the electrical connector 14. Based on the detection results of the power-on detection module 17, the total duration of the aging test for the display can be easily recorded; when a display crashes, the time of the crash and the time of restarting the test can be recorded. The power-on detection module 17 can be a single module, used to record the detection results of the display in each placement area; or multiple modules can be used to record the detection results of the display corresponding to one or more placement areas. Preferably, the test carriage 10 may also include a processing module, used to record the power-on status information of each display from the power-on detection module 17, and upload it to a host computer or server for further processing. The processing module can further process the data to obtain at least one of the following: the total test duration for each processor, the time of the crash relative to the start of the test, and the number of crashes, to facilitate the analysis and processing of displays that malfunction during the test, and to further supplement the test duration, etc.

[0051] Preferably, the test trolley 10 may include a multi-layer base 12 (e.g., two layers), with each layer having a corresponding separator 13 and an electrical connector 14 to accommodate more displays. When the placement areas in the multi-layer base 12 correspond one-to-one, some components may also be connected or integrated to reduce installation costs. For example, the partitions 133 in the separator 13 may extend through the multi-layer base 12 simultaneously, thereby achieving separation of placement areas in the multi-layer base 12.

[0052] Preferably, the test trolley 10 also includes swivel casters 112 to facilitate the movement of the test trolley 10.

[0053] Reference Figure 6 The diagram illustrates an embodiment of the electronic device transport and testing system of the present invention. The electronic device transport and testing system includes the aforementioned test trolley 10, robotic arm transport module 20, and AGV (Automated Guided Vehicle) 30. The robotic arm transport module 20 transports the electronic device (hereinafter, taking a display as an example) to a placement area of ​​the test trolley 10 and aligns the power interface of the display with the corresponding electrical connector 14 of that placement area. The transport, placement, and alignment are all achieved by the movement of the display by the robotic arm transport module 20. Preferably, the robotic arm transport module 20 includes a visual positioning function to locate the test trolley 10 and each placement area therein, thereby aligning the power interface of the transported display with the corresponding electrical connector 14 of that placement area. After the test trolley 10 is loaded, the AGV 30 transports the test trolley 10 to the testing chamber and positions it so that the common electrical connector 15 in the test trolley 10 mates with a power supply connector 41 in the testing chamber.

[0054] The robotic arm handling module 20 moves the display to align the display's power interface with the corresponding electrical connector 14 in the placement area, and to align the display area with the corresponding placement area. This alignment is achieved using a vision positioning module within the robotic arm handling module 20. For example, the vision positioning module can align with alignment marks in the corresponding placement area or partition, and obtain the coordinates of the corresponding electrical connector relative to the alignment marks, and the coordinates of the display's power interface relative to the display's positioning point. Based on these coordinate and alignment information, the alignment of the moved display's power interface with the corresponding electrical connector 14 in the placement area is achieved, as well as, in another embodiment, the alignment of the moved display with the corresponding placement area. Alternatively, the vision positioning module can directly identify a portion of the physical boundary or structure of the corresponding placement area or partition, and obtain the coordinates of the corresponding electrical connector relative to the alignment marks, and the coordinates of the display's power interface relative to the display's positioning point. Alignment is achieved based on these three types of information. Furthermore, the vision positioning module can directly identify the position of the corresponding electrical connector, and then achieve alignment based on this position and the coordinates of the display's power interface relative to the display's positioning point. This invention is not limited to these methods. The coordinate information mentioned above can be obtained in advance by the visual positioning module and stored in the visual positioning module, or it can be manually entered by the operator and stored in the visual positioning module in advance.

[0055] Preferably, the test trolley 10 also includes a support member 111, which is located at the bottom of the test trolley 10 at a specific distance from the ground, so that the AGV trolley 30 can enter under the test trolley 10 and position the support member 111, thereby transporting or moving the test trolley 10. The AGV trolley 30 can lift the test trolley 10 for movement, or it can be positioned and moved together with the swivel casters 112 of the test trolley 10. The support member 111 can be part of the frame 11; the support member 111 can also be integrated with the base 12. When there are multiple bases 12, the support member 111 can be integrated with the lowest base 12. Preferably, the support member 111 has a specific shape or pattern to achieve precise positioning and lifting of the AGV trolley 30.

[0056] The AGV 30 can be a dedicated vehicle with a fixed transportation route, performing tasks such as transport from the robotic arm's handling point to the testing room, and from the testing room to other testing or packaging stations. The AGV 30 can also be a general-purpose vehicle dispatched by an AGV scheduling system, executing task instructions issued by the AGV scheduling system via a wireless network and uploading its own status, location, and other information.

[0057] The power connector 41 in the test chamber can be installed on the wall of the test chamber or on a power supply pile extending from the ground or wall. The AGV trolley 30 can transport and position the test trolley 10 to a precise location based on the positioning marks near the power connector 41 or a specific transport path, so as to facilitate the alignment and magnetic connection between the common power connector 15 in the test trolley 10 and a power connector 41 in the test chamber.

[0058] A mechanical auxiliary positioning structure can also be installed near the power supply connector 41 to fix the test carriage 10 before the power supply connector 41 is aligned with the magnetic connection, and to assist in the alignment and magnetic connection between the power supply connector 41 and the common power connector 15. The mechanical auxiliary positioning structure can be installed on the ground or wall, or it can be integrated with the power supply connector 41. Figure 5 In a preferred embodiment, a double hook 42 is used, which can be extended, retracted, or rotated by a cylinder 43 to hook the crossbar in the test trolley 10. The mechanical auxiliary positioning structure also helps maintain a stable electrical connection of the test trolley during testing, preventing accidental power outages. After testing, when the test trolley 10 needs to be removed, the cylinder 43 drives the double hook 42 to release the test trolley 10, at which point the power connector 41 can also be disconnected from the common power connector 15. In another embodiment, the mechanical auxiliary positioning structure can also be a floor lock, which can secure the casters of the test trolley 10.

[0059] The test chamber control module 40 is used to control the automatic opening and closing of the sliding door 45 of the test chamber based on the position information of the AGV 30. For example, when the AGV 30 approaches the sliding door 45, the test chamber control module 40 controls the automatic opening of the sliding door 45. When the AGV 30 moves away from the sliding door 45, the test chamber control module 40 controls the automatic closing of the sliding door 45. In another embodiment, when the AGV leaves the test chamber and moves away from the sliding door 45, the test chamber control module 40 controls the automatic closing of the sliding door 45. The test chamber control module 40 can obtain the position information of the AGV 30 through sensors installed at the sliding door 45, or in other words, obtain the approach or departure of the AGV 30. The test chamber control module 40 can also obtain the position information by receiving information from the AGV 30 indicating its approach or departure. The test chamber control module 40 can also obtain the above information through the control system of the AGV 30. The test chamber control module 40 can also combine the above methods to obtain the position information of the AGV trolley 30, thereby identifying the door opening and closing requirements. This invention is not limited thereto.

[0060] The test chamber is also equipped with a power supply connector 44 for monitoring whether the power supply connector is supplying power. The power supply connector 44 can also be connected to the power-on detection module 17 in the test trolley 10 via communication to obtain whether each display under test is powered normally. The test chamber control module 40 is also used to control the power supply connector 41 to supply power to the common power connector 15 of the test trolley 10.

[0061] In summary, the test trolley provided by this invention facilitates automatic power interface connection when loading electronic products, eliminating the need for manual plugging and unplugging of power cords and tidying them up. Furthermore, the test trolley can automatically connect to external power connectors. Additionally, it can automatically power on the electronic device under test and activate the test mode, while also monitoring and providing real-time feedback on the device's power-on status. This allows for precise control of test duration, ensuring consistency of test conditions and timely resolution of problems, saving retesting time, and improving test room uptime. It also eliminates the need for operators to press the power button on each electronic device to power it on and then select the test mode through multiple remote control operations.

[0062] The present invention has been described in the above-described embodiments; however, these embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. Conversely, any modifications and refinements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
