Description

Technical Field

[0001] This utility model belongs to the field of display screen technology, and in particular relates to a rapid positioning and testing device for OLED display screen assemblies. Background Technology

[0002] Organic light-emitting diode (OLED) displays are widely used in electronic products such as mobile phones, televisions, and wearable devices due to their advantages such as self-illumination, high contrast, thinness, wide viewing angle, and fast response speed.

[0003] On OLED display production lines, after the screen modules are assembled, they need to undergo electrical performance and display function testing. Currently, the common method is for operators to remove the screen from the assembly line and manually align and insert the ribbon cables onto the testing equipment. This process has significant drawbacks: First, manual alignment is inefficient, becoming a bottleneck in production cycle time; second, repeated insertion and removal can easily damage the delicate ribbon cable gold fingers or connector pins due to misalignment, causing unnecessary losses; finally, the poor consistency of manual operation may affect the stability of the test results. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an OLED display detection device based on gravity self-centering, which can achieve automatic and accurate positioning and quickly complete the detection connection.

[0005] This utility model provides an OLED display detection device based on gravity self-centering, including a gravity centering positioning bracket 1, an inclined surface 3 installed on the gravity centering positioning bracket 1, and a limiting stop 2 provided at the lower end of the inclined surface 3. The inclined slope 3 receives the OLED display 5 from the production line and causes the OLED display 5 to slide down under its own gravity until the end of it that is not connected to the ribbon cable 4 abuts against the limiting edge 2. A detection head 6 is provided at the corresponding position of the ribbon cable 4 on the inclined surface 3 for quick connection with the ribbon cable 4.

[0006] Furthermore, the inclined surface 3 has two limiting edges 2 below it, which are adjacent to each other and perpendicularly connected to form an L-shaped positioning angle.

[0007] Furthermore, the inclined surface 3 is a flat plate with a rectangular planar projection; the L-shaped positioning angle is set at the lowest point and is used to fit and position with the two sides adjacent to the OLED display screen 5.

[0008] Furthermore, a buffer pad is provided on the side of the two limiting edges 2 that contact the OLED display screen 5.

[0009] Furthermore, the inclined surface 3 is composed of multiple rectangular strips spliced ​​together.

[0010] Furthermore, the angle between the inclined plane 3 and the horizontal plane is 10° to 30°.

[0011] Furthermore, an avoidance hole is provided on the inclined surface 3, and the detection head 6 is located below the inclined surface 3, with its connecting end able to pass through or be located at the avoidance hole to align with the positioned ribbon cable 4.

[0012] Furthermore, the detection head 6 is mounted on the inclined surface 3 via a drive mechanism, which is used to adjust the position of the detection head 6.

[0013] Furthermore, the gravity centering positioning bracket 1 is connected to the inclined plane 3 via an angle adjustment device, which is used to adjust and lock the tilt angle of the inclined plane 3.

[0014] Furthermore, the angle adjustment device includes a support plate connected to the inclined plane 3, and the support plate has an arc-shaped adjustment groove; the locking bolt passes through the arc-shaped adjustment groove and locks the support plate to the gravity centering positioning bracket 1.

[0015] Beneficial effects: This invention simplifies the original multiple steps of "picking up, placing, aligning, and inserting" into a single "placing" action. The screen automatically slides down and is precisely positioned by gravity, significantly shortening the detection cycle and greatly improving production efficiency.

[0016] This invention achieves precise positioning in a two-dimensional plane by simultaneously fitting the L-shaped positioning angle with both sides of the screen, ensuring the consistency of the cable interface position after each placement and laying the foundation for reliable connection.

[0017] This invention avoids damage to the wiring, bending, or connectors caused by inaccurate manual alignment, thus reducing quality risks and material losses during the production process.

[0018] The core mechanism of this utility model is a mechanical gravity slide and a guard, which does not require complex sensors or vision systems, has low manufacturing cost, is easy to maintain, and has high stability.

[0019] This invention, through its adjustable tilt angle and customizable support bar structure, can be adapted to OLED displays of different sizes, weights, and specifications. Attached Figure Description

[0020] To make the content of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. The principles and features of the present invention are described below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The embodiments given are only for explaining the present invention and are not intended to limit the scope of the present invention. Example

[0024] like Figure 1 As shown, the present invention provides an OLED display detection device based on gravity self-alignment, which mainly consists of a gravity alignment positioning bracket 1, an inclined plane 3, and a detection head 6.

[0025] The gravity-aligned positioning bracket 1 serves as the main support frame of the device. The inclined plane 3 is fixedly mounted on the bracket 1 by a support structure, maintaining a suitable angle with the horizontal plane. The angle between the inclined plane 3 and the horizontal plane ranges from 10° to 30°, for example, 15° or 20°. At this angle, the screen can slide down smoothly without generating excessive impact.

[0026] At the lowest end of the inclined plane 3, two mutually perpendicular limiting edges 2 are fixedly installed, which together form an L-shaped positioning angle. The inclined plane 3 is preferably a rectangular flat plate, with the L-shaped positioning angle located at one of its apex corners. When the operator places the OLED display 5 on the inclined plane 3, the screen naturally slides down under the action of gravity, and its two adjacent sides will eventually fit tightly against the inner side of the L-shaped positioning angle, thereby completing precise positioning. To cushion impacts and prevent scratches on the screen, a cushioning pad made of rubber or silicone can be attached to the inner side of the limiting edges 2.

[0027] As another implementation, the inclined slope 3 can also be composed of multiple parallel support bars, which can reduce weight and reduce the contact area with the screen back panel, thus reducing the risk of scratches.

[0028] The detection head 6 is the core component for completing the electrical connection. In this embodiment, a clearance hole is formed on the inclined surface 3. The detection head 6 is located below the inclined surface 3, and its FPC connector (i.e., electrical connection interface) is aligned with the clearance hole. When the screen 5 slides down and is positioned, the interface end of its ribbon cable 4 is also just hovering or slightly touching above the clearance hole, perfectly aligned with the detection head 6. Subsequently, the ribbon cable 4 can be inserted into the connector of the detection head 6 automatically or manually, or the detection head 6 can be pushed up by a drive mechanism to complete the insertion.

[0029] To further enhance automation, the detection head 6 can be mounted on a drive mechanism, such as a small cylinder or electric push rod. When the sensor detects that the screen 5 has been positioned, the control system triggers the drive mechanism to precisely push the detection head 6 to complete the connection with the ribbon cable 4; after the detection is completed, the drive mechanism then drives the detection head 6 to reset and separate.

[0030] To optimize the device's adaptability to different screens, an angle adjustment mechanism is added between the gravity-aligned positioning bracket 1 and the inclined plane 3. This mechanism includes a support plate rigidly connected to the back of the inclined plane 3, with an arc-shaped adjustment groove on the plate. A locking bolt passes through this arc-shaped groove and is ultimately fixed to the bracket 1. When angle adjustment is needed, simply loosen the locking bolt to push the inclined plane 3 to rotate around its hinge point, changing the tilt angle. After adjustment, retighten the bolt to lock it in place. This allows the device to flexibly adapt to screens with different coefficients of friction or different weights, ensuring reliable sliding and accurate positioning.

[0031] This invention enables rapid, accurate, and automated docking of OLED displays, reducing the labor intensity of operators and improving production efficiency and the testing quality of OLED displays.
