Description

Technical Field

[0001] The utility model relates to the technical field of display panel testing, in particular to a plug-in point screen testing device for multiple connectors of a module display screen. Background Art

[0002] After the module screen is bound to the iron or plastic shell, it needs to be tested for screen grading before shipment. At this time, the only connectors that can be used for the electrical test points are mostly located on the back of the module screen, and are generally a dual-connector structure: a 6-10pin power port connector and a 30-96pin high-density port connector or piano cover signal connector. The current display panel process enters the module stage, and after the connector is packaged and bound to the iron or plastic shell, it is usually placed on a manual inspection platform or a semi-automatic platform for manual wiring and then AOI (Automated Optical Inspection) or manual inspection to determine the product grade before shipment.

[0003] After the ARM is placed on the stage, for production safety reasons (the ARM's active area does not overlap with the human operating area), a safe distance is usually maintained between the equipment placement position and the wiring insertion position. After the stage is moved to the wiring insertion position, it must be erected to facilitate manual wiring insertion. Sometimes, spot checks are conducted manually. This typically takes 7-12 seconds, impacting AOI inspection efficiency. Utility Model Content

The transfer mechanism drives the crimping / plugging module to move to the bottom of the connector, and the crimping / plugging module contacts or plugs into the connector to perform a point screen test. After receiving the in-place signal, the control mechanism powers on and lights up the display screen, and the point screen test box starts testing. After the test is completed, the transfer mechanism drives the crimping / plugging module to leave the connector and return to the standby position. The whole process takes about 6 seconds. The main purpose of this application is to automatically crimp or plug the back-side connector of the display screen that needs to be tested. There is no need to move the stage to the manual plug-in position 2 for flipping and plugging. Automatic crimping or plugging can be performed directly at the AOI inspection position, without the need for manual plug-in station stay time, saving human intervention.

[0026] The transfer mechanism 2 is provided with a first transfer unit 21 and a second transfer unit 22, the first transfer unit 21 includes a first X-axis driver 211 and a first Y-axis driver 212, the second transfer unit 22 includes a second X-axis driver 221 and a second Y-axis driver 222, the first X-axis driver 211 and the second X-axis driver 221 are arranged in parallel in the frame 1, and the first Y-axis driver 212 and the second Y-axis driver 222 are respectively installed on the movable ends of the first X-axis driver 211 and the second X-axis driver 221.

[0027] The movable ends of the first Y-direction driver 212 and the second Y-direction driver 222 move relative to each other.

[0028] A crimping / plugging module 3 is installed at the movable end of each of the first Y-direction driver 212 and the second Y-direction driver 222 , and the plug connectors of the crimping / plugging module 3 are arranged upward.

[0029] The frame 1 includes an upper frame 11, a lower frame 12, and a vertical rod 13 for connecting and fixing the upper frame 11 to the lower frame 12. The lower frame 12 extends horizontally outward to form a mounting area, in which the support frame 5 is mounted. The lower end surface of the lower frame is equipped with multiple universal wheels to facilitate the movement of the screen test setup.

[0030] The clamping mechanism 4 enables the power port and the signal port of the product to face outward horizontally and be located outside the upper frame 11 .

[0031] The crimping / plugging module 3 includes a fixed seat 31, a Z-direction drive 32, an R-direction drive 33 and a plug connector 34.

The crimping / plugging module provided in the embodiment of the present application integrates optical, mechanical and other components into a set of smaller automatic plugging mechanisms, realizing fully automatic plugging technology for the 6-pin power port without taking up too much space. The automatic plugging mechanism is matched with different connectors through the R-direction driver 33, and can be integrated into the Inline line equipment to meet the multi-station mode and improve product detection efficiency.

[0036] A method for testing the plug-in point screen of multiple connectors of a modular display screen comprises the following steps:

[0037] S1: Depending on the different positions of the product to be tested (for example, when corresponding to different models), the first transfer unit 21 and / or the second transfer unit 22 are used to move the crimping / plug-in module 3 toward the product. When the connector 342 moves to the vicinity of the 6-pin power port connector interface end of the display panel, the distance between the connector and the connector 342 is measured by the rangefinder 9, and the connector 342 is raised to the photographing position (i.e., the position of the connector) by the Z-axis driver 32. The measured position of the connector is photographed, and the camera module 36 provides a correction value.

[0038] S2: Utilize the R-axis driver 33 to rotate the connector 342 on the base to the desired angle. The Z-axis driver 32 then raises the connector 342 to the height indicated by the rangefinder 9 until the connector 342 is aligned with the product's connector interface. In this embodiment, the display panel's connector interface is oriented in the Y direction, thus requiring Y-axis insertion. Utilize the first Y-axis driver 212 and / or the second Y-axis driver 222 to provide active force, moving the connector 342 closer to the connector. The miniature peek camera 7 observes the correct insertion position. If not, the R-axis driver 33, the Z-axis driver 32, the first Y-axis driver 212, and / or the second Y-axis driver 222 are used to adjust the connector to the correct insertion position.

[0039] S3: Plug the connector 342 into the connector interface end, and measure the plugging force on the connector 34 through the force measuring module 37; in this embodiment, it is Y-direction plugging. If the Y-direction plugging force is insufficient or too large, the force measuring module 37 (a force gauge in this embodiment) will alarm and trigger re-plugging.

[0040] S4: After the connection is completed, the screen test box 6 is used to perform a screen test on the product to be tested. Subsequent testing can be performed after the screen is tested.

[0041] This embodiment takes the connector opening in the Y direction as an example. If the connector opening is in the X direction, the X axis is used as the main power axis for plugging. The crimping / plugging module 3 and the screen-pointing test equipment provided by the present invention can correspond to product connector openings in multiple directions. The present invention uses a new automatic plug-in mechanism to replace manual plug-in, reducing human operation risks. It realizes fully automatic alignment, plug-in, screen-pointing and other action processes at the module section AOI inspection station, improving equipment production efficiency and increasing product yield.

[0042] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
