[0002] With the rapid development of the smartphone industry, the phone screen, as one of the main components of a phone, directly affects the user experience. Before installation, the phone screen needs to be inspected for defects such as dust. However, traditional equipment cleans and dries the phone screen and then directly places it on a conveyor belt to the inspection station. This method of transportation makes it easy for dust to fall onto the phone screen, causing it to fail inspection. In addition, traditional inspection and transportation equipment need to be configured independently, resulting in insufficient coordination between the inspection and transportation processes, scattered equipment, and large space occupation.

Detailed Implementation

[0036] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please read carefully. Figures 1 to 5The mobile phone screen rotation detection device includes a rotating assembly 1 and a blowing assembly 2. Specifically, the rotating assembly 1 includes a rotating member 11 and rotating clamping members 12. The rotating member 11 includes a connecting part 111 and a clamping part 112. The two clamping parts 112 are fixedly connected to both sides of the connecting part 111. Each of the two clamping parts 112 can clamp a mobile phone screen, and the included angle between the two clamping parts 112 can be 180°. Multiple rotating clamping members 12 protrude from the clamping part 112, which allows the airflow of the blowing assembly 2 to flow vertically over the mobile phone screen, and allows the light source 51 to illuminate the screen from directly below during detection. Two horizontally spaced rotating clamping members 12 can be referred to as a group. Two groups of rotating clamping members 12 can be provided on one clamping part 112, and these two groups of rotating clamping members 12 are spaced apart vertically. A mobile phone screen can be clamped by two groups of rotating clamping members 12, so that the mobile phone screen will not fall off even if either group of rotating clamping members 12 is released.

[0038] It is conceivable that the two clamping parts 112 can have the same shape, and the two clamping parts 112 can be rotatably arranged around the connecting part 111. Both clamping parts 112 are provided with clamping grooves 115, and the opening direction of the clamping grooves 115 is upward or downward. The rotating member 11 rotates 180° around the center position of the connecting part 111, so that the opening direction of the clamping grooves 115 on both sides does not change with each rotation of the rotating member 11, thereby improving the synergy of the detection process.

[0039] The blowing assembly 2 is located on one side of the rotating assembly 1 in the vertical direction, with the airflow direction parallel to the vertical direction. The rotating assembly 1 can clamp and rotate the mobile phone screen, thus facilitating airflow to all sides of the screen. The airflow blown by the blowing assembly 2 is clean air, further preventing dust from falling onto the screen. Furthermore, in the entire working environment, the airflow from the blowing assembly 2 covers the rotating assembly 1, the horizontal conveying assembly 3, the vertical conveying assembly 4, and the detection assembly 5. Therefore, after the mobile phone screen enters the mobile phone screen rotation detection device, it is subjected to the dust removal effect of the blowing assembly 2 at each detection stage.

[0040] It's important to know that while mobile phone screen rotation detection devices can operate in cleanrooms, the cleanroom cannot be guaranteed to be completely dust-free due to factors such as staff entering and exiting the premises and dust removal equipment. Therefore, dust may still fall onto the mobile phone screen.

[0041] The mobile phone screen rotation detection device includes two horizontal conveying components 3, which are located on both sides of the rotating part 11. Each horizontal conveying component 3 includes a horizontal moving part 31 and a horizontal clamping part 32. When the horizontal conveying component 3 moves horizontally, part of the horizontal moving part 31 can pass through the clamping groove 115 on the clamping part 112 to transport the mobile phone screen from the horizontal clamping part 32 to the rotating clamping part 12.

[0042] In addition, a horizontal conveying component 3 is located on one side of the rotating component 11, and a rotating clamping component 12 is located on the other side of the rotating component 11. Therefore, the horizontal clamping component 32 needs to pass through the rotating component 11. In order to facilitate passing through the rotating component 11, symmetrical through slots 116 are provided on opposite sides of the clamping groove 115. The size of the through slot 116 is larger than the size of the horizontal clamping component 32, so that when the horizontal conveying component 3 moves horizontally, the horizontal clamping component 32 can pass through the through slot 116.

[0043] Along the horizontal direction, the projection of the horizontal clamp 32 is located between the projections of the two sets of rotating clamps 12. The mobile phone screen is set along the vertical direction, with its long side parallel to the horizontal direction and its short side parallel to the vertical direction. Since the two sets of rotating clamps 12 are set at intervals along the vertical direction, one set of rotating clamps 12 can clamp the upper side of the short side of the mobile phone screen, and the other set of rotating clamps 12 can clamp the lower side of the short side of the mobile phone screen. The horizontal clamp 32 can clamp the middle of the short side of the mobile phone screen. Thus, during the transportation of the mobile phone screen, the rotating clamps 12 and the horizontal clamps 32 will not interfere with each other.

[0044] The mobile phone screen rotation detection device also includes a vertical conveying assembly 4, which is located between the horizontal conveying assembly 3 and the rotating assembly 1. The vertical conveying assembly 4 includes a vertical moving part 41 and a vertical clamping part 42. The vertical conveying assembly 4 is used to clamp multiple mobile phone screens, and the vertical clamping part 42 can clamp the lower side of the short side of the mobile phone screen, so that the vertical clamping part 42 and the horizontal clamping part 32 will not interfere with each other during the transportation of the mobile phone screen. In addition, when the horizontal moving part 31 moves, the vertical moving part 41 is in the lowest position. At the lowest position, the vertical conveying assembly 4 and the mobile phone screen are located under the horizontal conveying assembly 3, and the vertical moving part 41 does not move. The mobile phone screen can be moved from the vertical conveying assembly 4 to the rotating assembly 1 through the horizontal conveying assembly 3, realizing the transportation between different workstations.

[0045] In this embodiment, the detection component 5 includes a light source 51 and a camera 52. The light source 51 can move horizontally. When the rotating component 11 rotates, the light source 51 remains stationary in its initial position. The initial position is spaced apart from the rotating component 11, thus not affecting the rotation of the rotating component 11. When the detection component 5 detects the mobile phone screen, the light source 51 can move to directly below the mobile phone screen, with light entering the lower side of the screen vertically. The light source 51 illuminates the screen from directly below, enabling defects such as dust and scratches to form high contrast in the image of the camera 52, facilitating identification. The camera 52 is located on one side of the mobile phone screen in the horizontal direction. In addition, a black plate is also spaced apart on the back of the mobile phone screen. The black back plate can absorb light penetrating the screen, reducing reflection and stray light interference, further improving image quality and the sensitivity of defect detection.

[0046] The rotating component 1 is fixedly installed on a platform with a slot, that is, a slot is cut out of a part of the platform. The shape of the slot is not limited. When the rotating component 11 rotates, it passes through the slot on the platform at least partially. The rotating component 11 can reach the inspection station in one rotation, which optimizes the inspection process and reduces the area occupied by the equipment.

[0047] In this embodiment, the clamping part 112 is provided with a clamping air inlet 113 and a clamping air outlet 114. The clamping air inlet 113 is located on the upper side of the clamping part 112, and the clamping air outlet 114 is located on the side of the clamping part 112 and corresponds to the mobile phone screen. The size of the clamping air outlet 114 is smaller than the size of the clamping air inlet 113, which can accelerate the airflow and improve the dust removal effect; and along the direction away from the connecting part 111, the size of the clamping air inlet 113 and the clamping air outlet 114 gradually increases, which can optimize the airflow distribution, ensure that the airflow evenly covers the entire screen surface, and avoid damage to the screen caused by excessive local airflow.

[0048] Importantly, the blower assembly 2 can be located above the rotating assembly 1. When the rotating assembly 1 initially rotates horizontally, the airflow from the blower assembly 2 from top to bottom can directly enter the clamping air inlet 113. At this time, the airflow velocity at the clamping air outlet 114 is at its maximum, and the airflow can blow away dust from the upper part of the phone screen. As the rotating assembly 1 rotates, the flow area between the clamping air inlet 113 and the vertically downward airflow gradually decreases. Especially after the rotation angle of the rotating assembly 1 is greater than 90°, the flow area between the clamping air inlet 113 and the vertically downward airflow is zero. The airflow enters the clamping air inlet 113 solely by the rotation speed of the rotating assembly 1. At this time, the airflow velocity at the clamping air outlet 114 is low, and the airflow can blow away dust from the lower middle part of the phone screen. This achieves the goal of blowing air out of different positions on the phone screen by rotating the component 11 at different rotation positions.

[0049] In addition, the rotation speed of the rotating part 11 can be adjusted according to different mobile phone screen sizes, so that the rotating part 11 rotates at a constant speed or at a variable speed.

[0050] In this embodiment, the mobile phone screen rotation detection device further includes a dust removal component 6, which is spaced apart from the connecting part 111. The dust removal component 6 has a dust removal air inlet 61 and a dust removal air outlet 62. The size of the dust removal air outlet 62 is smaller than the size of the dust removal air inlet 61. The dust removal air inlet 61 is located on the upper side of the dust removal component 6, and the dust removal air outlet 62 is located on the side of the dust removal component 6 and corresponds to one side of the mobile phone screen, blowing air onto one side of the mobile phone screen. The clamping air outlet 114 corresponds to the other side of the mobile phone screen, blowing air onto the other side of the mobile phone screen. Thus, while the rotating component 11 clamps and rotates the mobile phone screen, it achieves simultaneous air blowing from both sides, more thoroughly removing dust from the surface of the mobile phone screen.

[0051] This embodiment also provides a method for detecting mobile phone screen rotation, including:

[0052] S1, the vertical conveyor assembly 4 is located at the highest position, and the vertical clamp 42 clamps multiple cleaned and dried mobile phone screens;

[0053] S2, the horizontal clamping member 32 clamps a mobile phone screen, the vertical moving member 41 drives the vertical clamping member 42 and the remaining mobile phone screen to move downward to the lowest position, and the horizontal moving member 31 drives the horizontal clamping member 32 and the mobile phone screen to move horizontally to the rotating component 1.

[0054] S3, the rotating clamping member 12 clamps the mobile phone screen, the horizontal clamping member 32 releases the mobile phone screen, and the horizontal moving member 31 drives the horizontal clamping member 32 back to the original position;

[0055] S4, the rotating component 11 drives the rotating clamping component 12 and the mobile phone screen to rotate to the detection station by a preset angle, and the detection component 5 takes a picture of the mobile phone screen for detection.

[0056] In step S1, at the highest position, the vertical conveying component 4 and the entire mobile phone screen are at the same level as the horizontal conveying component 3.

[0057] In step S4, the two sets of rotating clamping parts 12 alternately loosen and tighten, reducing the obstruction of the detection field of view by the rotating clamping parts 12 and ensuring that the camera 52 can clearly capture defects in the screen edge and key areas. By analyzing the detection results, corresponding measures are immediately taken, which improves the detection efficiency to a certain extent. When the mobile phone screen is found to have dust, when the rotating part 11 drives the rotating clamping parts 12 and the mobile phone screen to rotate at a preset angle, the clamping air outlet 114 and the dust removal air outlet 62 blow air to both sides of the mobile phone screen to achieve secondary dust removal, which can improve the dust removal efficiency to a certain extent.

[0058] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
