Description

Technical Field

[0001] This utility model relates to the field of touch screen glass detection technology, specifically to a touch screen glass flipping component. Background Technology

[0002] AOI (Automated Optical Inspection) equipment is a high-precision, high-efficiency inspection technology that uses light sources and cameras to perform non-contact automated inspection of printed circuit boards (PCBs) or other electronic components. AOI equipment is capable of fully inspecting the appearance defects of touch screen glass (hereinafter referred to as glass). Before use, the glass undergoes cutting, edge grinding, cleaning, and drying before entering the AOI full inspection equipment.

[0003] During glass cutting and edging, tiny cracks (edge ​​chipping) may occur on the lower edge of the glass. Because these cracks are located on the lower surface and are relatively small, they may be difficult to detect during inspection. Current technology primarily involves manually rotating the finished glass 180 degrees before placing it onto the feed conveyor belt of an AOI (Automated Optical Inspection) system to detect surface defects. However, manually rotating the glass can easily lead to uneven stress or impacts, causing damage and rendering the glass unusable. Furthermore, it is highly dependent on manual labor, resulting in high labor costs. Utility Model Content

[0004] The present invention aims to provide a touch screen glass flipping component to solve the problem that manual flipping of glass in the prior art easily causes glass damage and scrap.

[0005] To solve the above problems, this utility model provides the following technical solution:

[0006] A touchscreen glass flip assembly includes a support base, a flip motor fixedly mounted on the support base, a flip arm fixedly sleeved on the movable end of the flip motor, the axis of the flip arm being perpendicular to the axis of the movable end of the flip motor; a flip plate fixedly connected to the flip arm, a space for glass flipping is left between the flip plate and the flip motor, and multiple vacuum suction cups fixedly mounted on the flip plate.

[0007] The working principle and beneficial effects of this utility model:

[0008] This solution places the glass on multiple vacuum suction cups. A vacuum pump creates negative pressure on the suction cups to hold the glass in place, preventing it from falling during the flipping process. A flipping motor drives a flipping arm to rotate, which in turn rotates the flipping plate 180 degrees. At this point, the glass flips onto the feed conveyor belt of the AOI (Automated Guided Inspection) equipment. The vacuum suction cups no longer create negative pressure to hold the glass, and it automatically falls onto the feed conveyor belt. Furthermore, sufficient space is provided between the flipping plate, support base, and flipping motor for glass flipping. The axis of the flipping arm is perpendicular to the axis of the moving end of the flipping motor, thus providing maximum space for glass flipping and preventing damage or scrapping caused by collisions between the glass and the flipping motor / support base during the flipping process.

[0009] In this solution, the glass is placed on multiple vacuum suction cups, and the rotating arm rotates 180 degrees to replace manual rotation of the glass, thereby effectively controlling the glass rotation path. Furthermore, multiple vacuum suction cups simultaneously hold the glass, ensuring uniform force on the glass and effectively preventing damage and scrapping. In addition, sufficient space is reserved for glass rotation to prevent collisions between the glass and the rotation motor and support base during the rotation process, which could cause damage and scrapping.

[0010] Preferably, the flipping plate is symmetrically arranged along the axis of the flipping arm. This optimized design allows for the simultaneous placement and flipping of more glass, improving production efficiency.

[0011] Preferably, the movable end of the flipping motor is fixedly sleeved with a limiting plate, the limiting plate is fixedly provided with a limiting protrusion, and the support base is symmetrically fixedly provided with limiting blocks that alternately abut against the limiting protrusion.

[0012] When the movable end of the flipping motor drives the flipping plate to rotate, the limiting protrusion abuts against the limiting block on one side, thereby limiting the movable end of the flipping motor to rotate exactly 180 degrees, so that the flipping plate is rotated to face the feeding conveyor belt of the AOI full inspection equipment, thus facilitating the stable placement of glass on the feeding conveyor belt; when the limiting protrusion abuts against the limiting block on the other side, the flipping plate is in a horizontal state, thus facilitating the placement of glass onto the flipping plate.

[0013] Preferably, a circular plate is fixedly sleeved on the movable end of the flip motor, and a limiting protrusion is fixedly provided on the circular plate. A limit sensor, which works in conjunction with the limiting protrusion, is symmetrically fixedly provided on the support base. The limit sensor is electrically connected to the flip motor. When the limiting protrusion passes the limit sensor, it triggers the limit sensor to send a signal to the flip motor, causing the flip motor to stop, thus causing the movable end of the flip motor to rotate exactly 180 degrees.

[0014] Ideally, the vacuum suction cups are multiple and evenly spaced. The evenly spaced vacuum suction cups enhance the adhesion to the glass. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of a touchscreen glass flip assembly according to the present invention;

[0016] Figure 2 This is a diagram showing the equipment layout. Detailed Implementation

[0017] The following detailed description illustrates the specific implementation method:

[0018] The reference numerals in the accompanying drawings include: 1. Flip arm; 2. Vacuum suction cup; 3. Flip plate; 4. Glass; 5. Flip motor; 6. Limiting plate; 7. Limiting protrusion; 8. Limiting sensor; 9. Support base.

[0019] In the following statements, directional terms such as "left," "right," "up," and "down" are based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the direction while maintaining their relative positions, it will not affect the implementation of the plan.

[0020] Example 1: A touchscreen glass flip assembly, such as Figure 1 and Figure 2 As shown, the device includes a support base 9, on which a flipping motor 5 is fixedly mounted. A flipping swing arm 1 is fixedly sleeved at the movable end of the flipping motor 5, and the axis of the flipping swing arm 1 is perpendicular to the axis of the movable end of the flipping motor 5. A flipping plate 3 is fixedly connected to the flipping swing arm 1, and a space is left between the flipping plate 3 and the flipping motor 5 for the glass 4 to flip. A vacuum suction cup 2 is fixedly mounted on the flipping plate 3. The vacuum suction cup 2 is provided with negative pressure by a vacuum pump (not shown in the figure). How the vacuum pump provides negative pressure to the vacuum suction cup 2 to achieve adsorption is a common technology in this field and will not be described in detail here.

[0021] This design places glass 4 on vacuum suction cup 2. A vacuum pump creates negative pressure on vacuum suction cup 2 to hold glass 4 in place, preventing it from falling during the flipping process. The flipping motor 5 drives the flipping arm 1 to rotate, causing the flipping plate 3 to flip 180 degrees. At this point, glass 4 flips onto the feed conveyor belt of the AOI full inspection equipment. The vacuum pump no longer provides negative pressure to vacuum suction cup 2 to hold glass 4 in place, and glass 4 automatically falls onto the feed conveyor belt of the AOI full inspection equipment. Furthermore, sufficient space is provided between the flipping plate 3, the support base 9, and the flipping motor 5 for glass 4 to flip. The axis of the flipping arm 1 is perpendicular to the axis of the moving end of the flipping motor 5, thus providing maximum space for glass 4 to flip, preventing damage and scrapping caused by collisions between glass 4 and the flipping motor 5 and support base 9 during the flipping process.

[0022] In this solution, glass 4 is placed on vacuum suction cup 2, and the rotating swing arm 1 rotates 180 degrees to replace manual rotation of glass 4, thereby effectively controlling the rotation path of glass 4. At the same time, vacuum suction cup 2 holds glass 4, and glass 4 is subjected to uniform force, thereby effectively avoiding damage and scrapping of glass 4. In addition, sufficient space is reserved for glass 4 to rotate to prevent damage and scrapping caused by collision between glass 4 and rotating motor 5 and support base 9 during the rotation process.

[0023] Example 2: The difference from Example 1 is that the movable end of the flip motor 5 is fixedly sleeved with a limit plate 6. The limit plate 6 has a limit protrusion 7. The support base 9 is symmetrically provided with limit sensors 8 that cooperate with the limit protrusions 7. The limit sensors 8 and the flip motor 5 are electrically connected. When the limit protrusion 7 passes the limit sensor 8 on one side, it sends a signal to the flip motor 5, causing the flip motor 5 to stop, so that the movable end of the flip motor 5 rotates exactly 180 degrees.

[0024] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
