Description

Technical Field

[0001] This application relates to the field of display panel manufacturing technology, and in particular to a loading and unloading device, testing equipment and testing system. Background Technology

[0002] With the continuous development of technology, electronic devices such as mobile phones, computers, tablets, and watches have been widely used in various industries. As a human-computer interaction product, display panels are increasingly widely used. After the display panel is manufactured and before it is put into assembly, a lighting test is required. This test is crucial to ensuring the quality of the display panel.

[0003] Currently, display panels consist of a screen and an FPC (Flexible Printed Circuit) connected to the screen. To optimize the display panel structure and improve its performance, the FPC is attached to the back of the display panel. During testing of such panels, the FPC must be connected to an external circuit before the display panel can be powered on. Because the projection directions of the screen and the FPC overlap, the display panel needs to be flipped multiple times during testing to establish connection between the FPC and the external probe module. This makes the connection process complex and significantly impacts testing efficiency. Summary of the Invention

[0004] Therefore, it is necessary to provide a loading and unloading device, testing equipment, and testing system to address the problems of complex operation and low testing efficiency in connecting the display panel of the FPC to the back of the screen.

[0007] At least one material-carrying mechanism, the material-carrying mechanism including a carrier and an opening and closing cover assembly, the carrier being rotatably disposed on the frame and including a base and a cover plate rotatably disposed on the base, the base having a first bearing cavity for carrying the screen body and a second bearing cavity for carrying the flexible flat cable, and during the circulation of the carrier, the first bearing cavity is close to the first region and the second bearing cavity is close to the second region, the opening and closing cover assembly being disposed on the frame and close to the second region, the opening and closing cover assembly being connectable to or detachable from the cover plate to close or open the second bearing cavity;

[0008] The loading and unloading assembly is disposed on the frame and can move in the direction of extending into or out of the second bearing cavity. The loading and unloading assembly is used for loading and unloading the flexible flat cable in the second bearing cavity.

[0009] In one embodiment, the vehicle includes a first vehicle and a second vehicle;

[0010] The first carrier is rotatably disposed on the frame and has the first bearing cavity. The first carrier has a first position for avoiding the flexible flat cable and a second position for bearing the flexible flat cable.

[0012] In one embodiment, the loading and unloading assembly includes a multi-axis motion component and at least one straightening module connected to the multi-axis motion component. The multi-axis motion component is disposed on the frame, and the straightening module can move in the direction of extending into or out of the second bearing cavity for loading and unloading the flexible flat cable in the second bearing cavity.

[0013] In one embodiment, the straightening module includes a mounting base, at least one suction head, and a fork. The mounting base is disposed on the multi-axis moving part, the suction head is disposed on the mounting base and can adsorb the flexible flat cable, and the fork is movably disposed on the mounting base and can be connected to or separated from the second carrier.

[0014] In one embodiment, the opening and closing cover assembly includes a fixed base and a push-pull module movably disposed on the fixed base, the push-pull module being able to connect to or separate from the cover plate during movement.

[0015] In one embodiment, the push-pull module includes a rotating component, a push-pull component, and at least one connecting component disposed on the push-pull component. The rotating component is disposed on the fixed base, the push-pull component is throttle-connected to the rotating component, and the connecting component is movably disposed on the push-pull component and can be connected to or separated from the cover plate.

[0016] In one embodiment, the material loading mechanism further includes a line body disposed on the frame, the line body having loading / unloading positions and a picking position, and the carrier being rotatably disposed on the line body between the loading / unloading positions and the picking position.

[0017] In one embodiment, the line includes a clearance groove for avoiding the cover plate.

[0018] In one embodiment, the loading and unloading device further includes an image detection module, which is disposed on the frame and close to the second area, and is used to acquire the pose of the display panel.

[0025] In the aforementioned loading / unloading device, testing equipment, and testing system, the carrier moves along the frame to a position close to the loading / unloading assembly and the opening / closing cover assembly. Since the first bearing cavity is close to the first region and the second bearing cavity is close to the second region, the opening / closing cover assembly can rotate and separate the cover plate from the base in the second region. After the second bearing cavity is opened and exposed, the loading / unloading assembly moves towards the direction of extending into the second bearing cavity, loading the flexible flat cable into the second bearing cavity. In this way, both the opening / closing cover assembly and the loading / unloading assembly complete the loading / unloading operation of the flexible flat cable on the side closest to the second region. The carrier does not need to be repeatedly flipped during the frame's movement to complete the loading / unloading and conductive connection operation of the flexible flat cable, simplifying the conductive connection steps of the display panel and improving the testing efficiency of the display panel.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0049] Currently, when performing electrical connection operations on flexible flat cables (such as FPCs) bonded to the surface of a screen, taking the case where the FPC is bonded to the back of the screen as an example, the display panel is typically rotated with the screen facing up and the FPC facing down. However, to perform the electrical connection operation, the display panel must be flipped to the FPC-facing position to facilitate the connection. After the connection is completed, the display panel must be flipped back to the FPC-facing position to continue the process. This frequent flipping and repositioning of the display panel during the electrical connection operation complicates the process and severely impacts the testing efficiency of the display panel.

[0050] It should be noted that in the above description, "up" and "down" refer to directions. For example, during the circulation of the display panel, the side of the display panel that is away from the workbench is "up," and the side of the display panel that faces the workbench is "down."

[0051] Based on this, see Figures 1-4As shown, this application provides a loading and unloading device 100, which includes a frame 110, at least one loading mechanism 120, and a loading and unloading assembly 150. The loading mechanism 120 includes a carrier 130 and an opening and closing cover assembly 140. The loading and unloading device 100 is used for loading and unloading display panels 200. The display panel 200 includes a screen body 210 and a flexible flat cable 220. The orthogonal projection of the flexible flat cable 220 onto the screen body 210 is at least partially located inside the screen body 210, such as the flexible flat cable 220 being adhered to the surface of the screen body 210, and at least partially extending into the inside of the screen body 210.

[0052] The rack 110 has opposing first regions 111 and second regions 112. Figure 1 From a perspective example, the first region 111 is the upper part of the rack 110, and the second region 112 is the lower part of the rack 110. A carrier 130 is mounted on the rack 110 and can move on it. The carrier 130 includes a base 131 and a cover plate 132. The cover plate 132 is rotatably mounted on the base 131, for example, by means of a pivot, hinge, or other means. The base 131 has a first bearing cavity 133 and a second bearing cavity 134. The first bearing cavity 133 supports the screen 210, and the second bearing cavity 134 supports the flexible flat cable 220. Optionally, both the first bearing cavity 133 and the second bearing cavity 134 are contoured grooves to improve the bearing stability of the screen 210 in the first bearing cavity 133 and the bearing stability of the flexible flat cable 220 in the second bearing cavity 134. During the movement of the carrier 130, the first bearing cavity 133 is close to the first region 111, and the second bearing cavity 134 is close to the second region 112. Thus, during the movement of the display panel 200 while it is carried on the carrier 130, the display panel 200 is positioned such that the screen body 210 faces the first region 111 and the flexible cable 220 faces the second region 112.

[0053] The loading / unloading assembly 150 is disposed on the frame 110 and can move in the direction of extending into or out of the second bearing cavity 134. The loading / unloading assembly 150 is used for loading and unloading the flexible flat cable 220 in the second bearing cavity 134. For example, when the loading / unloading assembly 150 moves in the direction of extending into the second bearing cavity 134, after the loading / unloading assembly 150 moves into the second bearing cavity 134, the loading / unloading assembly 150 can act on the flexible flat cable 220 by suction, pulling, clamping, etc. The loading / unloading assembly 150 separates the flexible flat cable 220 from the screen body 210 to load the flexible flat cable 220 into the second bearing cavity 134, or the loading / unloading assembly 150 removes the flexible flat cable 220 from the second bearing cavity 134 and resets it to the surface of the screen body 210. Furthermore, when the loading and unloading assembly 150 moves toward exiting the second bearing cavity 134, and after the loading and unloading assembly 150 exits the second bearing cavity 134, the loading and unloading assembly 150 will not interfere with the conductive connection, testing and other operations of the display panel 200.

[0054] The opening and closing cover assembly 140 is disposed on the frame 110 and is located near the second region 112. The opening and closing cover assembly 140 can be connected to or separated from the cover plate 132 to close or open the second bearing cavity 134. For example, when loading the display panel 200, the opening and closing cover assembly 140 is connected to the cover plate 132, and the opening and closing cover assembly 140 moves along... Figure 6 As shown, F1 drives the cover plate 132 to rotate and separate relative to the base 131. After the second bearing cavity 134 is opened and exposed, the loading and unloading assembly 150 moves in the direction of extending into the second bearing cavity 134, and the loading and unloading assembly 150 loads the flexible flat cable 220 into the second bearing cavity 134. After the display panel 200 is loaded, the opening and closing cover assembly 140 connects to the cover plate 132, and the opening and closing cover assembly 140 moves along... Figure 6 As shown, F2 drives the cover plate 132 to rotate relative to the base 131 and close, thereby sealing the second bearing cavity 134. It should be noted that when the opening and closing action of the carrier 130 is not required, the opening and closing cover assembly 140 is separated from the cover plate 132, and the opening and closing cover assembly 140 will not interfere with the continued circulation, testing and other operations of the display panel 200.

[0055] The aforementioned loading and unloading device 100, with carrier 130 moving on the frame 110 to a position close to loading and unloading assembly 150 and opening and closing cover assembly 140, since the first bearing cavity 133 is close to the first region 111 and the second bearing cavity 134 is close to the second region 112, the opening and closing cover assembly 140 can perform rotational separation of cover plate 132 and base 131 in the second region 112. After the second bearing cavity 134 is opened and exposed, the loading and unloading assembly 150 moves in the direction of extending into the second bearing cavity 134, and the loading and unloading assembly 150 loads the flexible flat cable 220 into the second bearing cavity 134. Thus, the flexible flat cable 220 and the opening / closing cover assembly 140 are both located on the side closer to the second region 112. The opening / closing cover assembly 140 and the loading / unloading assembly 150 both complete the loading / unloading operation of the flexible flat cable 220 on the side closer to the second region 112. The carrier 130 does not need to be repeatedly flipped during the flow of the frame 110 to complete the loading / unloading and conductive connection operation of the flexible flat cable 220, which simplifies the conductive connection steps of the display panel 200 and can improve the testing efficiency of the display panel 200.

[0056] In one embodiment, see Figures 1-4 As shown, the carrier 130 includes a first carrier 135 and a second carrier 136. The first carrier 135 is rotatably disposed on the frame 110 and has a first bearing cavity 133 for bearing the screen 210. Exemplarily, as in this embodiment, the first carrier 135 includes a base plate and a cover plate 132. The first carrier 135 has a first position and a second position, the first position being a position to avoid the flexible flat cable 220, and the second position being a position to bear the flexible flat cable 220.

[0057] The second carrier 136 is movably disposed on the first carrier 135, and the second carrier 136 has a second bearing cavity 134 for bearing the flexible flat cable 220. The second carrier 136 can move between a first position and a second position. Specifically, when loading the display panel 200, firstly, the screen body 210 is placed in the first bearing cavity 133 of the first carrier 135, and the flexible flat cable 220 is attached to the screen body 210; then, since the second carrier 136 is located in the first position, the second carrier 136 avoids the flexible flat cable 220 and picks up the flexible flat cable 220 by suction, pulling or other means to separate the flexible flat cable 220 from the screen body 210; next, the second carrier 136 moves from the first position to the second position; finally, the flexible flat cable 220 is placed in the second bearing cavity 134 of the second carrier 136, and the display panel 200 can be loaded. Conversely, when unloading the display panel 200, firstly, the flexible flat cable 220 is picked up by means of suction, pulling, etc., to remove the flexible flat cable 220 from the second carrier cavity 134; then, the second carrier 136 moves from the second position toward the first position to reset the second carrier 136; finally, the flexible flat cable 220 is reset to the surface of the screen body 210.

[0058] Thus, by moving the second carrier 136 between the first position and the second position, interference is avoided in the separation operation of the flexible flat cable 220 and the screen 210, which facilitates the loading and unloading operation of the display panel 200.

[0059] For the display panel 200 where the flexible flat cable 220 is bonded to the surface of the screen 210, there is no gap between the flexible flat cable 220 and the screen 210, making it impossible to perform testing operations on the display panel 200. Therefore, see [reference needed]. Figures 1-4 As shown, the bearing surface of the first bearing cavity 133 and the bearing surface of the second bearing cavity 134 have an included angle α, where 0 < α < 180°. When performing electrical tests on the display panel 200, the screen body 210 is placed in the first bearing cavity 133, and the flexible flat cable 220 is picked up by means of suction or pulling, and then placed in the second bearing cavity 134. The second bearing cavity 134 is tilted relative to the first bearing cavity 133, which facilitates the placement of the screen body 210 and the flexible flat cable 220 and does not damage the flexible flat cable 220.

[0060] Specifically, the included angle α between the bearing surface of the first bearing cavity 133 and the bearing surface of the second bearing cavity 134 can be any one of 15°, 30°, 45°, 60°, 75°, 90°, 105°, 120°, 135°, 150°, and 165°. Of course, in other feasible embodiments, the included angle α between the bearing surface of the first bearing cavity 133 and the bearing surface of the second bearing cavity 134 is not limited to the specific angles mentioned above, and can also be other angles within the range of 0 to 180°, such as values ​​within the range of 0 to 60°, 60° to 120°, and 120° to 180°.

[0061] In one embodiment, see Figures 1-4 As shown, the loading / unloading assembly 150 includes a multi-axis motion component 151 and at least one aligning module 152. The multi-axis motion component 151 is mounted on the frame 110 and may include, but is not limited to, a multi-axis robotic arm or a multi-axis fine-tuning platform. The aligning module 152 is drivenly connected to the multi-axis motion component 151 and can move in the direction of extending into or out of the second bearing cavity 134. The aligning module 152 is used for loading and unloading flexible flatbed cables 220 in the second bearing cavity 134.

[0062] For example, the multi-axis motion component 151 drives the alignment module 152 to move in a direction that extends into the second support cavity 134. After the alignment module 152 moves into the second support cavity 134, it can perform loading and unloading operations of the flexible flat cable 220 within the second support cavity 134. After the loading and unloading operations of the flexible flat cable 220 are completed, the multi-axis motion component 151 drives the alignment module 152 to move in a direction that exits the second support cavity 134, so that the alignment module 152 exits the second support cavity 134, avoiding interference with the conductive connection, testing, and other operations of the display panel 200.

[0063] For details, please refer to [link / reference]. Figure 5 As shown, the straightening module 152 includes a mounting base 1521, at least one suction head 1522, and a fork 1523. The mounting base 1521 is disposed on the multi-axis moving part 151, and the suction head 1522 is disposed on the mounting base 1521, and the suction head 1522 can adsorb the flexible flat cable 220. Optionally, there are multiple suction heads 1522, and multiple suction heads 1522 cooperate to adsorb the flexible flat cable 220, which can ensure the flatness of the flexible flat cable 220 during the adsorption process. The fork 1523 is movably disposed on the mounting base 1521, and the fork 1523 can be connected to or separated from the second carrier 136. For example, if the second carrier 136 has a boss 1361, the shift fork 1523 has a locking portion that can engage with the boss 1361. The shift fork 1523 can be locked onto the boss 1361 to connect with the second carrier 136, or the shift fork 1523 can disengage from the boss 1361 to separate from the second carrier 136. Of course, in other feasible embodiments, the shift fork 1523 can also be connected or separated from the second carrier 136 by means of magnetic attraction or other methods.

[0064] It should be noted that in this embodiment, the shift fork 1523 is connected to a drive source, which can independently drive the shift fork 1523 to move, thereby decoupling the movement of the shift fork 1523 and the suction head 1522. The connection or separation action of the shift fork 1523 and the second carrier 136, and the adsorption action of the suction head 1522 on the flexible cable 220 are independent of each other, thus avoiding interference between the shift fork 1523 and the suction head 1522. Furthermore, the suction head 1522 is also connected to a drive source, which can drive the suction head 1522 to move independently, thereby decoupling the movement of the suction head 1522 from that of the multi-axis motion component 151. For example, after the multi-axis motion component 151 drives the straightening module 152 to move to the second bearing cavity 134, since the loading and unloading movement stroke of the flexible flat cable 220 is small, the suction head 1522 can move independently and perform suction, pulling and other operations of the flexible flat cable 220, thereby improving the movement flexibility of the suction head 1522 and reducing the movement accuracy requirements of the multi-axis motion component 151, thus reducing the loading and unloading cost of the loading and unloading device 100.

[0065] For example, when loading the display panel 200, firstly, the screen body 210 is placed in the first bearing cavity 133; then, the multi-axis motion component 151 moves and moves the straightening module 152 to the second bearing cavity 134, the suction head 1522 moves to a position where it can pick up the flexible flat cable 220, the suction head 1522 picks up the flexible flat cable 220, and the straightening module 152 picks up the flexible flat cable 220 to remove the flexible flat cable 220 bonded to the surface of the screen body 210. 0. Pull up; then, the drive source drives the shift fork 1523 to move, and when the shift fork 1523 is connected to the second carrier 136, the shift fork 1523 drives the second carrier 136 to move from the first position to the second position; finally, after the second carrier 136 moves to the second position, the suction head 1522 releases the adsorption effect on the flexible flat cable 220 and places the flexible flat cable 220 in the second bearing cavity 134 to achieve the orderly feeding of the screen 210 and the flexible flat cable 220. For example, during the unloading operation of the display panel 200, firstly, the multi-axis motion component 151 moves and moves the straightening module 152 to the second bearing cavity 134. The suction head 1522 moves to a position where it can absorb the flexible flat cable 220. The suction head 1522 absorbs the flexible flat cable 220, and the straightening module 152 picks up the flexible flat cable 220 to pull up the flexible flat cable 220 in the second bearing cavity 134. Next, the drive source drives the fork 1523 to move. When the fork 1523 is connected to the second carrier 136, the fork 1523 drives the second carrier 136 to move from the second position to the first position. Finally, after the second carrier 136 moves to the first position, the suction head 1522 releases its absorption of the flexible flat cable 220 and resets the flexible flat cable 220 to the surface of the screen body 210, so as to realize the straightening unloading of the screen body 210 and the flexible flat cable 220.

[0066] In one embodiment, see Figures 1-4 and Figure 6 As shown, the opening and closing cover assembly 140 includes a fixed base 141 and a push-pull module 142. The fixed base 141 is disposed on the frame 110, and the push-pull module 142 is movably disposed on the fixed base 141. The push-pull module 142 can be connected to or separated from the cover plate 132 during movement. Thus, by moving the push-pull module 142 relative to the fixed base 141, the push-pull module 142 can be connected to or separated from the cover plate 132. When the push-pull module 142 is connected to the cover plate 132, the push-pull module 142 can drive the cover plate 132 to open and close according to a preset path. When the push-pull module 142 is separated from the cover plate 132, the opening and closing cover assembly 140 will not interfere with the display panel 200 to continue to perform operations such as circulation and testing.

[0067] Specifically, see Figures 1-4 and Figure 6As shown, the push-pull module 142 includes a rotating member 1421, a push-pull member 1422, and at least one connecting member 1423. The rotating member 1421 is disposed on the fixed base 141. If the rotating member 1421 is driven by a rotation drive source, the rotation of the rotating member 1421 can be driven by the rotation drive source. The push-pull member 1422 is driven by the rotating member 1421. The connecting member 1423 is movably disposed on the push-pull member 1422, and the connecting member 1423 can be connected to or separated from the cover plate 132. For example, if the connecting member 1423 is driven by a drive source, the drive source can drive the extension and retraction of the connecting member 1423 relative to the push-pull member 1422. The connecting member 1423 will not have a positional interference problem with the carrier 130, and the connecting member 1423 can be connected to the cover plate 132 to perform the opening and closing operation of the carrier 130.

[0068] For example, when loading and unloading the display panel 200 is required, the rotating component 1421 drives the pushing and pulling component 1422 along... Figure 6 As shown in Figure F2, the push-pull member 1422 rotates to the vicinity of the cover plate 132. When this member moves, the connecting member 1423 moves relative to the push-pull member 1422 and connects to the cover plate 132. After the connecting member 1423 is connected to the cover plate 132, the rotating member 1421 drives the push-pull member 1422 along... Figure 6 As shown, the movement in direction F1 opens the carrier 130 and exposes the second bearing cavity 134, allowing the loading / unloading assembly 150 to load the flexible cable 220. Conversely, after the loading / unloading operation of the display panel 200 is completed, the connector 1423 moves relative to the push-pull member 1422 and separates from the cover plate 132. After the connector 1423 separates from the cover plate 132, the rotating member 1421 drives the push-pull member 1422 along... Figure 6 The movement in direction F1 is shown to reset the push-pull module 142, so as to avoid interference from the opening and closing cover assembly 140 to the continued circulation, testing and other operations of the display panel 200.

[0069] It should be noted that, due to the brittleness and thinness of the display panel 200, if the carrier 130 were to automatically open and close using elastic force, it would be prone to significant shaking during the opening and closing process, which could easily damage the display panel 200. In this application, a push-pull module 142 is connected to the cover plate 132. During rotation, the push-pull module 142 can limit the rotation path of the cover plate 132, improving the consistency and stability of the opening and closing path of the carrier 130. This prevents the carrier 130 from damaging the display panel 200 and improves the test yield of the display panel 200.

[0070] In one embodiment, see Figures 1-4As shown, the loading and unloading device 100 also includes an image detection module 170, which is disposed on the frame 110 and close to the second region 112. The image detection module 170 is used to acquire the position and orientation of the display panel 200. Thus, by acquiring the position and orientation of the display panel 200 through the image detection module 170, the positional accuracy of the screen 210 within the first bearing cavity 133 and the positional accuracy of the flexible flat cable 220 within the second bearing cavity 134 are ensured, thereby improving the loading and unloading quality of the display panel 200.

[0071] Furthermore, the image detection module 170 is communicatively connected to the loading / unloading assembly 150 and the opening / closing assembly 140. The image detection module 170 can acquire the position and pose information of the display panel 200 and feed the position and pose information of the display panel 200 back to the control unit. The control unit can control the loading / unloading assembly 150 and the opening / closing assembly 140 to perform corresponding operations based on the position and pose information of the display panel 200.

[0072] Specifically, see Figures 1-4 As shown, the image detection module 170 includes at least a first camera 171 and a second camera 172. The first camera 171 is used to acquire the pose of the screen 210, and the imaging surface of the first camera 171 is parallel to the screen 210 to ensure the image quality of the screen 210 acquired by the first camera 171. The second camera 172 is used to acquire the pose of the flexible flat cable 220, and the imaging surface of the second camera 172 is parallel to the flexible flat cable 220 placed in the second carrier cavity 134 to ensure the image quality of the flexible flat cable 220 acquired by the second camera 172.

[0073] In one embodiment, see Figures 1-4 and Figure 7 As shown, the loading mechanism 120 also includes a feed line 160. The feed line 160 is disposed on the frame 110 and has loading / unloading positions and a pick-up position. The carrier 130 is rotatably disposed on the feed line 160 between the loading / unloading positions and the pick-up position. Exemplarily, in this embodiment, the carrier 130 performs loading operations of the screen 210 into the first bearing cavity 133 at the loading / unloading positions, or the carrier 130 performs unloading operations of the display panel 200 at the loading / unloading positions, and the carrier 130 performs loading / unloading operations of the flexible flat cable 220 into the second bearing cavity 134 at the pick-up position.

[0074] For display panels 200 with different loading qualities, separate unloading operations are required. For example, if the image detection module 170 detects that the pose of the display panel 200 matches the preset pose (meaning the display panel 200 is accurately positioned within the carrier 130), the carrier 130 carrying the accurately positioned display panel 200 needs to be unloaded (OK). Conversely, if the image detection module 170 detects that the pose of the display panel 200 does not match the preset pose (meaning the display panel 200 is mispositioned within the carrier 130), the carrier 130 carrying the mispositioned display panel 200 needs to be unloaded (NG). When unloading the display panel 200 (NG), because of the positional deviation between the display panel 200 and the carrier 130, continuing to close the carrier 130 for unloading will damage the display panel 200 during the rotational closing process of the cover plate 132, and will also reduce the loading and unloading efficiency of the display panel 200.

[0075] Based on this, see Figures 1-4 and Figure 7 As shown, the line body 160 includes a clearance groove 161 for clearing the cover plate 132. Thus, during NG unloading of the display panel 200, the cover plate 132 and the base 131 are in an open state, such as when the carrier 130 is in position... Figure 6 When the display panel 200 is in the open state, NG (Not Good) material is unloaded. The base 131 flows on the conveyor belt 160, and the clearance groove 161 avoids the cover plate 132. The conveyor belt 160 can adapt to the unloading operation of the carrier 130 in different states. Furthermore, there is no need to close the carrier 130 during NG unloading, which improves the loading and unloading efficiency of the display panel 200 and prevents damage to the display panel 200 due to the rotation of the cover plate 132.

[0076] In one embodiment, see Figures 1-4 As shown, the material loading mechanism 120 also includes a material picking component 180. The material picking component 180 is disposed on the frame 110 and is located on the side of the line 160 near the material picking position. Thus, when the carrier 130 flows to the material picking position on the line 160, the material picking component 180 picks up the carrier 130 that has flowed to the material picking position, and holds the carrier 130 in the loading and unloading state, so as to avoid the line 160 interfering with the opening and closing of the cover of the carrier 130 and the loading and unloading operation of the flexible cable 220.

[0077] For details, please refer to [link / reference]. Figure 6As shown, the material handling assembly 180 includes a mounting frame 181 and a material handling module 182. The mounting frame 181 is disposed on the frame 110, and the material handling module 182 is movably disposed on the mounting frame 181. Thus, when the carrier 130 flows to the material handling position on the line 160, the material handling module 182 moves to the position where it can handle the carrier 130. After the material handling module 182 handles the carrier 130, it moves away from the line 160 to remove the carrier 130 from the line 160, thus avoiding interference from the line 160 with the opening and closing of the carrier 130 and the loading and unloading operations of the flexible cable 220.

[0078] In this embodiment, the material handling module 182 includes a power source 1821 and a clamping member 1822, which is connected to the power source 1821. The power source 1821 drives the clamping member 1822 to change its clamping space, thereby enabling material handling of the carrier 130 at the material handling position. Alternatively, in other feasible embodiments, the material handling module 182 includes an adsorption seat, which can hold the carrier 130 by adsorption. Thus, by holding the carrier 130 with the adsorption seat, the loading and unloading efficiency of the carrier 130 is improved while maintaining its stability, and damage to the carrier 130 is reduced.

[0079] To improve the load-bearing stability of the carrier 130 on the display panel 200, the carrier 130 is provided with a locking member 137. The locking member 137 is used to lock the cover plate 132 in the closed base 131 state, preventing the carrier 130 from opening and closing on its own during testing, transportation, etc. For example, the locking member 137 is a hook or buckle provided on the base 131. In one embodiment, see... Figures 1-4 and Figure 8 and Figure 9 As shown, the opening and closing cover assembly 140 also includes an unlocking component 143, such as a push rod or lever, and the unlocking component 143 is connected to a drive source such as a cylinder or motor. When it is necessary to unlock the carrier 130, the unlocking component 143 can move towards the locking component 137 and act on the locking component 137 to automatically unlock the carrier 130, facilitating the opening and closing of the carrier 130.

[0080] Furthermore, see Figures 1-4 and Figure 10As shown, this application also provides a testing device 300, which includes a loading / unloading device 100 as described above. The loading / unloading device 100 includes multiple loading mechanisms 120, and the loading / unloading assembly 150 can move in the direction of extending into or exiting the second bearing cavity 134 of any carrier 130. For example, in this embodiment, the loading / unloading device 100 includes two loading mechanisms 120. If the two loading mechanisms 120 are defined as a first loading mechanism 121 and a second loading mechanism 122, the loading / unloading assembly 150 can perform alternating loading / unloading operations on the first loading mechanism 121 and the second loading mechanism 122 to improve the loading / unloading efficiency of the display panel 200.

[0081] Of course, in other feasible embodiments, the loading and unloading device 100 may include three, four or other loading mechanisms 120. This application does not limit the specific number of loading mechanisms 120 and can set it according to actual needs.

[0082] In one embodiment, see Figures 1-4 and Figure 10 As shown, the loading / unloading assembly 150 includes a multi-axis moving component 151 and multiple leveling modules 152. The multiple leveling modules 152 are all drivenly connected to the multi-axis moving component 151, and each leveling module 152 corresponds to a multiple loading mechanism 120. For example, still taking two loading mechanisms 120 as an example, the loading / unloading assembly 150 also includes two leveling modules 152. If the two leveling modules 152 are defined as a first leveling module 1524 and a second leveling module 1525, the first loading mechanism 121 and the second loading mechanism 122 are located on opposite sides of the loading / unloading assembly 150, with the first loading mechanism 121 closer to the first leveling module 1524 and the second loading mechanism 122 closer to the second leveling module 1525.

[0083] Thus, the multi-axis motion component 151 moves the first aligning module 1524 away from the first loading mechanism 121 to avoid it. The opening and closing cover assembly 140 of the first loading mechanism 121 opens and closes the cover of the carrier 130. At the same time, the multi-axis motion component 151 moves the second aligning module 1525 towards the second loading mechanism 122. After the second aligning module 1525 extends into the second bearing cavity 134 of the carrier 130 of the second loading mechanism 122, the second aligning module 1525 can perform the loading and unloading operation of the flexible cable 220 in the second bearing cavity 134 of the second loading mechanism 122. Alternatively, the multi-axis motion component 151 moves the first aligning module 1524 toward the direction of approaching the first loading mechanism 121. After the first aligning module 1524 extends into the second bearing cavity 134 of the carrier 130 of the first loading mechanism 121, the first aligning module 1524 can perform the loading and unloading operation of the flexible cable 220 in the second bearing cavity 134 of the first loading mechanism 121. At the same time, the multi-axis motion component 151 moves the second aligning module 1525 toward the direction away from the second loading mechanism 122 to avoid the second loading mechanism 122. The opening and closing cover assembly 140 of the second loading mechanism 122 performs the opening and closing cover operation of the carrier 130.

[0084] The aforementioned testing equipment 300, through multiple regularization modules 152, performs alternating loading and unloading operations on multiple material loading mechanisms 120, which can ensure the continuity of loading and unloading of the display panel 200 and improve the loading and unloading efficiency of the display panel 200.

[0085] Additionally, see Figures 1-4 As shown, this application also provides a testing system, which includes a testing machine and multiple loading / unloading devices 100 as described above. Along the flow direction of the carrier 130, at least two loading / unloading devices 100 are located on opposite sides of the testing machine. For example, along the flow direction of the carrier 130, the loading / unloading device 100 upstream of the testing machine can perform docking / insertion operations on the flexible flat cable 220, completing the conductive connection operation of the flexible flat cable 220; the loading / unloading device 100 downstream of the testing machine can perform separation / stripping operations on the flexible flat cable 220, releasing the conductive connection of the flexible flat cable 220. For example, after the flexible flat cable 220 completes the conductive connection operation at the loading / unloading device 100 upstream of the testing machine, the carrier 130 carrying the display panel 200 flows to the testing machine for testing. After the test is completed, the display panel 200 flows through the carrier 130 to the loading / unloading device 100 downstream of the testing machine to release the conductive connection of the flexible flat cable 220.

[0086] In the aforementioned testing system, both the opening / closing cover assembly 140 and the loading / unloading assembly 150 complete the loading / unloading of the flexible flat cable 220 on the side closest to the second region 112. The carrier 130 does not need to be repeatedly flipped during the rotation of the frame 110 to complete the loading / unloading and conductive connection operations of the flexible flat cable 220, simplifying the conductive connection steps of the display panel 200 and improving the testing efficiency of the display panel 200.

[0087] The following combination Figures 1-10 The loading operation of the display panel 200 in this application is described in detail.

[0088] First, the screen body 210 is placed in the first bearing cavity 133, and the carrier 130 carrying the screen body 210 flows from the upper and lower material positions to the material picking position on the production line 160. Then, the material picking module 182 moves to the position where it can pick up the material carrier 130. After the material picking module 182 picks up the material carrier 130, it moves away from the production line 160. Then, the rotating component 1421 drives the push-pull component 1422 along... Figure 6 As shown in Figure F2, when the push-pull member 1422 moves to the vicinity of the cover plate 132, the connecting member 1423 moves relative to the push-pull member 1422 and connects with the cover plate 132. After the connecting member 1423 is connected to the cover plate 132, the unlocking member 143 moves towards the locking member 137 and acts on the locking member 137 to unlock the carrier 130. The rotating member 1421 drives the push-pull member 1422 along... Figure 6 The device moves in the direction F1 to open the carrier 130 and expose the second carrier cavity 134. Next, the image detection module 170 acquires the pose of the flexible flat cable 220 and feeds this pose information back to the control unit. Then, the control unit controls the multi-axis motion component 151 to move the alignment module 152 to the second carrier cavity 134, where the suction head 1522 adheres to the flexible flat cable 220, separating it from the screen 210. Next, the fork 1523 moves and connects to the second carrier 136, moving the carrier 136 from the first position to the second position. Then, after the second carrier 136 reaches the second position, the suction head 1522 releases its adsorption of the flexible flat cable 220 and places the cable 220 into the second carrier cavity 134. Subsequently, the image detection module 170 acquires the position information of the flexible flat cable 220 relative to the second bearing cavity 134, and feeds back the pose information of the flexible flat cable 220 to the control unit. Finally, if the pose of the flexible flat cable 220 matches the preset pose, the control unit controls the opening and closing cover assembly 140 to move, that is, the rotating component 1421 drives the push-pull component 1422 along... Figure 6The F2 direction is rotated to close the carrier 130 and perform OK unloading of the carrier 130 through the line body 160; if the position of the flexible flat cable 220 does not conform to the preset position, the control unit controls the carrier 130 to be in the open state on the line body 160 to perform NG unloading of the carrier 130.

[0089] 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.

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.
