Description

Technical Field

[0001] The utility model relates to the technical field of touch screen glass detection, and particularly relates to a touch screen glass flipping and conveying assembly. Background Art

[0002] AOI equipment is a high-precision and high-efficiency detection technology, which performs non-contact automated inspection on printed circuit boards (PCBs) or other electronic components through light sources and cameras. The AOI equipment has the function of fully inspecting the appearance defects of touch screen glass (hereinafter referred to as glass). Before use, the glass enters the AOI full-inspection equipment after being cut, edge-ground, cleaned, and dried.

[0003] During the production processes of glass cutting and edge-grinding, fine cracks (edge chipping) may occur on the lower edge of the glass. Since these cracks are on the lower surface of the glass and are relatively fine, they may not be easily detected during the inspection process. For this reason, in the prior art, the processed glass is mainly manually flipped 180 degrees and then sent into the detection port of the AOI full-inspection equipment to detect the appearance defects of the glass by using the AOI equipment. However, the method of manually flipping the glass is prone to situations where the glass is unevenly stressed or knocked, resulting in damage and scrapping of the glass. Moreover, during the process of sending the glass into the detection port of the AOI full-inspection equipment, the glass is also extremely likely to collide with the casing of the AOI full-inspection equipment and cause damage. Summary of the Utility Model

[0004] The utility model aims to provide a touch screen glass flipping and conveying assembly to solve the problem that the glass in the prior art is easily damaged by knocking.

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

[0006] A touch screen glass flipping and conveying assembly includes a frame. The frame is provided with a flipping mechanism and a conveying mechanism. The conveying mechanism is used for feeding towards the detection port of the AOI full-inspection equipment, and the flipping mechanism is used for flipping the glass onto the conveying mechanism. The flipping mechanism includes a support base. A flipping motor is fixedly arranged on the support base. A flipping swing arm is fixedly sleeved on the movable end of the flipping motor. The axis of the flipping swing arm is perpendicular to the axis of the movable end of the flipping motor. The flipping swing arm is fixedly connected with a flipping plate. A space for the glass to flip is left between the flipping plate and the flipping motor. The flipping plate is fixedly provided with vacuum suction cups.

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

[0008] In this solution, the glass is placed on a vacuum suction cup, and the vacuum suction cup generates negative pressure to hold the glass, preventing the glass from falling during the flipping process. The flipping motor drives the flipping swing arm to rotate, and the flipping swing arm drives the flipping plate to flip 180 degrees. At this time, the glass flips to directly above the transmission mechanism, and multiple vacuum suction cups do not generate negative pressure to hold the glass, and the glass automatically falls onto the transmission mechanism. The transmission mechanism feeds the glass towards the detection port of the AOI full inspection device. Moreover, there is a space for the glass to flip between the flipping plate, the support base, and the flipping motor. The axis of the flipping swing arm is perpendicular to the axis of the movable end of the flipping motor, thereby providing the largest space for the glass to flip, preventing the glass from colliding with the flipping motor and the support base during the flipping process and causing damage and scrapping.

[0009] In this solution, by placing the glass on multiple vacuum suction cups and using the flipping swing arm to rotate 180 degrees to replace manual flipping of the glass, the flipping path of the glass can be effectively controlled. Moreover, multiple vacuum suction cups hold the glass simultaneously, and the glass is evenly stressed, effectively avoiding damage and scrapping of the glass. Additionally, there is enough space reserved for the glass to flip to prevent the glass from colliding with the flipping motor and the support base during the flipping process and causing damage and scrapping. The transmission mechanism is used for directional feeding to prevent the glass from colliding with the casing of the AOI full inspection device and causing damage.

[0010] Preferably, the flipping plate is symmetrically arranged along the axis of the flipping swing arm. This optimized solution can place more glasses for flipping simultaneously, improving production efficiency.

[0011] Preferably, a circular plate is fixedly sleeved on the movable end of the flipping motor. The circular plate is fixedly provided with a limit protrusion. The support base is symmetrically and fixedly provided with limit sensors that cooperate with the limit protrusion. The limit sensors are electrically connected to the flipping motor.

[0012] When the movable end of the flipping motor drives the flipping plate to rotate, the limit protrusion passes by one side of the limit sensor, and the limit sensor sends a signal to the flipping motor, and the flipping motor stops working, thereby restricting the movable end of the flipping motor to just flip 180 degrees, making the flipping plate just flip to be directly opposite to the feeding conveyor belt of the AOI full inspection device, facilitating the glass to be placed stably on the feeding conveyor belt. Similarly, when the limit protrusion passes by the other side of the limit sensor, at this time, the flipping plate is in a horizontal state, facilitating the glass to be placed on the flipping plate.

[0013] Preferably, the limit block is provided with a limit sensor electrically connected to the flipping motor. When the limit protrusion contacts the limit block, the limit sensor is triggered to send a signal to the flipping motor, causing the flipping motor to stop.

[0014] Optimally, the number of the vacuum suction cups is multiple, and they are evenly spaced. Through multiple evenly spaced vacuum suction cups, the adsorption force on the glass is improved.

[0015] Preferably, the transmission mechanism is specifically a conveyor belt provided on the frame.

[0016] Preferably, the transmission mechanism is specifically a plurality of transmission rollers provided on the frame. Brief Description of the Drawings

[0021] The following is a further detailed description through specific embodiments:

[0022] The reference numerals in the accompanying drawings of the specification include: glass 1, transmission roller 2, flipping plate 3, vacuum suction cup 4, flipping motor 5, circular plate 6, limit protrusion 7, limit sensor 8, support base 9, frame 10, transmission motor 11, flipping swing arm 12.

[0023] In the following statements, the orientation words such as "left", "right", "up", and "down" are based on the orientation shown in the drawings. In practice, if the corresponding structure makes the same-direction change based on the orientation and keeps the relative position unchanged, it does not affect the implementation of the solution.

[0024] Embodiment 1: A touch screen glass flipping and transmitting assembly, as Figure 1 and Figure 4 shown, includes a frame 10. The frame 10 is provided with a flipping mechanism and a transmission mechanism. The transmission mechanism is used for feeding towards the detection port of the AOI full inspection device, and the flipping mechanism is used for flipping the glass 1 onto the transmission mechanism.

[0025] As Figure 3 shown, the transmission mechanism includes a transmission motor 11 fixedly connected to the frame 10. Nine transmission rollers 2 are rotatably connected to the frame 10. A chain is wound between the movable end of the transmission motor 11 and the nine transmission rollers 2. The transmission rollers 2 are fixedly sleeved with chain wheels for cooperating with the chain. By driving the chain to rotate by the transmission motor 11, after the chain drives the chain wheels to rotate, the nine transmission rollers 2 are further driven to rotate.

[0026] As Figure 2As shown in the figure, the flipping mechanism includes a support base 9 fixedly connected to the mechanism. The support base 9 is fixedly provided with a flipping motor 5. The movable end of the flipping motor 5 is fixedly sleeved with a flipping swing arm 12. The axis of the flipping swing arm 12 is perpendicular to the axis of the movable end of the flipping motor 5. The flipping swing arm 12 is fixedly connected to a flipping plate 3. A space for the glass 1 to flip is left between the flipping plate 3 and the flipping motor 5. The flipping plate 3 is fixedly provided with a plurality of vacuum suction cups 4. The plurality of vacuum suction cups 4 are provided with negative pressure by a vacuum pump. How the vacuum pump provides negative pressure to the vacuum suction cups 4 to generate suction for adsorption belongs to the common technical means in the field.

[0027] In this solution, the glass 1 is placed on the plurality of vacuum suction cups 4. The vacuum pump makes the plurality of vacuum suction cups 4 generate negative pressure, and the plurality of vacuum suction cups 4 suck the glass 1 to prevent the glass 1 from falling during the flipping process. The flipping motor 5 drives the flipping swing arm 12 to rotate. The flipping swing arm 12 drives the flipping plate 3 to flip 180 degrees. At this time, the glass 1 flips onto the transfer roller 2. The vacuum pump stops working, and the plurality of vacuum suction cups 4 do not generate negative pressure to suck the glass 1. The glass 1 automatically falls onto the transfer roller 2, and the transfer roller 2 feeds the glass 1 towards the detection port of the AOI full inspection device. Moreover, a space for the glass 1 to flip is left between the flipping plate 3 and the support base 9 and the flipping motor 5. The axis of the flipping swing arm 12 is perpendicular to the axis of the movable end of the flipping motor 5, so as to provide the largest space for the glass 1 to flip, to prevent the glass 1 from colliding with the flipping motor 5 and the support base 9 during the flipping process and causing damage and scrapping.

[0028] In this solution, by placing the glass 1 on the plurality of vacuum suction cups 4 and using the flipping swing arm 12 to rotate 180 degrees to replace manual flipping of the glass 1, the flipping path of the glass 1 can be effectively controlled. Moreover, the plurality of vacuum suction cups 4 suck the glass 1 at the same time, and the glass 1 is evenly stressed, so as to effectively avoid damage and scrapping of the glass 1. In addition, enough space for the glass 1 to flip is reserved to prevent the glass 1 from colliding with the flipping motor 5 and the support base 9 during the flipping process and causing damage and scrapping. The feeding is carried out in a directional manner through the transfer roller 2 to prevent the glass 1 from colliding with the casing of the AOI full inspection device and causing damage.

[0029] Embodiment 2: The movable end of the flipping motor 5 is fixedly sleeved with a circular plate 6. The circular plate 6 is fixedly provided with a limit protrusion 7. The support base 9 is symmetrically provided with limit sensors 8 for cooperating with the limit protrusion 7. The limit sensors 8 are electrically connected to the flipping motor 5.

[0030] When the movable end of the flipping motor 5 drives the flipping plate 3 to rotate, the limiting protrusion 7 passes by the limiting sensor 8 on one side. The limiting sensor 8 sends a signal to the flipping motor 5, and the flipping motor 5 stops working, thereby restricting the movable end of the flipping motor 5 to just flip 180 degrees, so that the flipping plate 3 just flips to face the feeding conveyor belt of the AOI full inspection device, facilitating the stable placement of the glass 1 on the feeding conveyor belt. Similarly, when the limiting protrusion 7 passes by the limiting sensor on the other side, at this time the flipping plate 3 is in a horizontal state, facilitating the placement of the glass 1 on the flipping plate 3.

[0031] The standard parts used in the present utility model can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art. Coupled with the circuit connection adopting the conventional connection method in the prior art, it will not be elaborated here.
