Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, and in particular to a feeding device for feeding a 2.5D glass cover plate with the user side facing upwards into a cleaning machine. Background Technology

[0002] 2.5D glass covers are a common type of protective cover for the display screens of smartphones, tablets, and other electronic devices. The term "2.5D" refers to a design where the glass edges are slightly curved, typically with the edges tilting slightly downwards. Compared to traditional flat glass designs, 2.5D glass is more visually and tactilely smoother and softer.

[0003] During the processing of 2.5D glass covers, before transferring them to the cleaning machine, the user-facing sides of the mixed 2.5D glass covers need to be flipped upwards to facilitate cleaning. Current technology involves a robotic arm picking up four pieces of glass from a tray and placing them on a secondary positioning platform. After positioning, a laser displacement sensor distinguishes the front and back of the glass. A flipping mechanism then flips the user-facing glass 180° and returns it to the secondary positioning platform. The secondary positioning platform moves backward, the flipping mechanism extends, and the secondary positioning mechanism moves to the flipping station. This flipping action is repeated to ensure that the user-facing sides of the glass on the secondary positioning platform are all facing upwards. Finally, a glass transfer mechanism transfers all four pieces of glass from the secondary positioning platform to the flatbed cleaning machine in one operation.

[0004] The existing feeding device uses a laser displacement sensor, which can only distinguish 2.5D glass with a flatness of 0.3-0.8. It cannot distinguish the front and back of glass with a flatness below 0.3, causing the glass to stack in the washing machine, resulting in defective glass and production line shutdown to troubleshoot the problem. Since the flipping mechanism is located below the secondary positioning platform after flipping the glass, the secondary positioning platform needs to be moved backward to avoid the flipping mechanism's range of motion; otherwise, it will interfere, which takes a long time.

[0005] Therefore, a new solution is needed. Utility Model Content

[0006] The main purpose of this utility model is to provide a feeding device for 2.5D glass cover plates.

[0007] To achieve the above objectives, this utility model provides a feeding device for 2.5D glass covers, used to move the 2.5D glass cover from a glass conveying device to a flatbed washing machine. The device includes a synchronous material handling module, a secondary positioning platform, an AI vision sensor, a flipping mechanism, a glass transfer mechanism, and a fixed base plate.

[0008] The synchronous material handling module is installed above the conveyor belt of the glass conveying device and is used to pick up multiple glass cover plates from the glass conveying device and place the picked-up multiple glass cover plates onto the secondary positioning platform.

[0009] The secondary positioning platform is installed on the fixed base plate and includes multiple flip positions for placing the glass cover plate, which are used to position the glass cover plate placed in the flip positions.

[0010] The glass transplanting mechanism includes a bracket and a lifting module. The lower end of the bracket is fixed to the upper surface of the fixed base plate. The lifting module is installed on the bracket and includes a first lifting component and a second lifting component connected below the first lifting component.

[0011] The AI ​​vision sensor is mounted on the bracket and located above the secondary positioning platform, and is used to identify the glass cover after positioning.

[0012] The flipping mechanism is mounted on the fixed base plate and located on one side of the secondary positioning platform. It is used to flip the glass cover 180° when the AI ​​vision sensor detects that the user's face is facing down.

[0013] The second lifting component of the glass transfer mechanism is used to pick up the flipped glass cover plate, and also to cooperate with the first lifting component to pick up the glass from the secondary positioning platform and place it on the flatbed washing machine after all the user sides of the glass cover plates are facing upwards.

[0014] The feeding device for 2.5D glass covers provided by this utility model has the following beneficial effects: In the feeding device for 2.5D glass covers provided by this utility model, the synchronous picking module picks up multiple glass covers from the tray of the glass conveying device and places them on the secondary positioning platform; after secondary positioning is completed on the secondary positioning platform, the AI ​​vision sensor 300 identifies the front and back of the glass covers; then, the flipping mechanism flips the glass covers facing down by 180°; after flipping, the second lifting component of the glass transfer mechanism 500 extends to pick up the flipped glass and retracts; if there are still glass covers facing down, the above actions are repeated; finally, only the glass facing up remains on the secondary positioning platform, and then it is transferred by the glass transfer mechanism... The first lifting component and the second lifting component above the glass facing the user pick up the glass from the secondary positioning platform and place it together on the flatbed washing machine. In this invention, the glass cover is repositioned by the secondary positioning platform before inspection, which can prevent the glass from being thrown out of the inspection field of view during loading and causing false inspection. By using an AI vision sensor, the front and back sides can be distinguished by the difference in the amount of reflection on the front and back sides of the glass edge R-corner, which can effectively determine the orientation of the glass cover and avoid the possible misjudgments in traditional methods. The transfer mechanism picks up the flipped glass above the flipping mechanism without affecting the flipping of the next piece of glass, which can greatly improve production efficiency, reduce potential risks, and ensure precise operation of the glass throughout the entire production process.

[0021] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate typical embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0023] Figure 1 The diagram shown is a structural schematic of a feeding device for a 2.5D glass cover plate according to an embodiment of this utility model. Figure 1 As shown, the feeding device for 2.5D glass covers provided by this utility model includes a synchronous picking module 100, a secondary positioning platform 200, an AI vision sensor 300, a flipping mechanism 400, a glass transfer mechanism 500, and a fixed base plate 600. In use, the synchronous picking module 100 picks up multiple glass covers from the tray of the glass conveying device 700 and places them on the secondary positioning platform 200; after secondary positioning is completed on the secondary positioning platform 200, the AI ​​vision sensor 300 identifies the front and back of the glass covers; then, the flipping mechanism 400 flips the glass covers facing down by 180°; after flipping, the second lifting component of the glass transfer mechanism 500 extends to pick up the flipped glass and retracts. If there are still glass covers facing down, the above actions are repeated; finally, only the glass facing up remains on the secondary positioning platform, and the glass on the secondary positioning platform is picked up by the first lifting component of the glass transfer mechanism 500 and the second lifting component above the glass facing up, and placed together on the flatbed washing machine. In this invention, the glass cover plate is repositioned by a secondary positioning platform before inspection, which can prevent the glass from being thrown out of the inspection field of view during loading and causing false detection. By using an AI vision sensor, the front and back sides can be distinguished by the difference in the amount of reflection on the front and back sides of the glass edge R-corner, which can effectively determine the orientation of the glass cover plate and avoid the possible misjudgments in traditional methods. The transfer mechanism picks up the flipped glass above the flipping mechanism without affecting the flipping of the next piece of glass, which can greatly improve production efficiency, reduce potential risks, and ensure precise operation of the glass throughout the entire production process.

[0024] Specifically, in one embodiment of this utility model, the synchronous material picking module 100 is installed above the conveyor belt of the glass conveying device 700, and is used to pick up multiple glass cover plates from the glass conveying device 600 and place the picked-up multiple glass cover plates onto the secondary positioning platform 200. Figure 2 The diagram shows a schematic representation of the synchronous material-picking module of a feeding device for 2.5D glass covers according to an embodiment of this utility model. As shown in Figure 2, the synchronous material-picking module 100 includes a first vertical column 110, a second vertical column 120, a first horizontal beam 130, a second horizontal beam 140, two material-picking components 150, and a pitch-changing component 160. The lower ends of the first vertical column 110 and the second vertical column 120 are fixed to the fixed base plate 600. These two columns are fixed to the bottom of the module, providing stable support by being mounted on the fixed base plate 600. The first horizontal beam 130 is fixed to the upper ends of the first vertical column 110 and the second vertical column 120, and is located above the conveyor belt of the glass conveying device 700. The second horizontal beam 140 is connected to one end of the first horizontal beam 130 and is perpendicular to the first horizontal beam 130 in the horizontal plane. The two material picking components 150 and the pitch-changing component 160 are mounted on the second horizontal beam 140. The first horizontal beam provides lateral support for the entire module by being fixedly connected to the vertical column, and the second horizontal beam provides support for different components, ensuring that they can move along a predetermined path. The pitch-changing component 160 is located between the two material picking components 150. The pitch-changing component is also a cylinder, used to adjust the distance between the two material picking components. The distance between the two material picking components can be adjusted as needed to provide more flexible material picking space for materials of different sizes.

[0025] Further, in one embodiment of this utility model, each material-picking component 150 includes a material-picking lifting cylinder 1501, a rotary cylinder 1502, a detection component 1503, and a material-picking suction cup 1504. The upper end of the material-picking lifting cylinder 1501 is mounted on the second horizontal beam 140, the lower end of the material-picking lifting cylinder 1501 is connected to the upper end of the rotary cylinder 1502, and the lower end of the rotary cylinder 1502 is connected to the material-picking suction cup 1504 and the detection component 1503. In use, the material-picking lifting cylinder drives the material-picking suction cup 1504 to pick up the glass cover plate from the tray of the glass conveying device. After the detection component 1503 detects that the glass cover plate has been picked up by the material-picking suction cup, the pitch-changing component increases the distance between the two material-picking components so that the glass cover plate can be placed on the secondary positioning platform. Subsequently, the rotary cylinder drives the material-picking suction cup to rotate 90 degrees to rotate the glass cover plate 90 degrees for easy placement on the secondary positioning platform. The lifting cylinder controls the up-and-down movement of the suction cup, ensuring it can vertically pick up the glass cover plates from the conveyor belt. A rotary cylinder drives the suction cup to rotate 90 degrees; during the glass cover plate loading process, the rotary cylinder adjusts the material's orientation for more precise placement at subsequent workstations. A detection component monitors the material's state during the picking process, ensuring the picking action is complete and the suction cup has successfully held the material, thus guaranteeing operational accuracy.

[0026] Specifically, in one embodiment of this utility model, the secondary positioning platform 200 is installed on the fixed base plate 600 and includes multiple flip positions for placing the glass cover plate. The platform is used to position the glass cover plate placed in the flip positions. By performing secondary positioning before glass detection, the product is positioned within the detection range of the vision sensor, preventing the glass from being thrown out of the detection field of view during loading and causing false detection.

[0027] Figure 3 The diagram shown is a structural schematic of a secondary positioning platform 200 for a 2.5D glass cover plate feeding device according to an embodiment of this utility model. Figure 3As shown, the secondary positioning platform 200 includes a first support module 210, a second support module 220, a positioning base plate 230, a positioning top plate 240, multiple X-axis positioning posts 250, an X-axis positioning stepper motor 260, multiple Y-axis positioning posts 270, and a Y-axis positioning stepper motor 280. The lower surfaces of the first support module 210 and the second support module 220 are respectively mounted on the fixed base plate 600. The upper surfaces of the first support module 210 and the second support module 220 are respectively connected to the two ends of the lower surface of the positioning base plate 230. By fixing the two support modules to the fixed base plate, a stable support is provided for the entire secondary positioning platform. The positioning top plate 240 is mounted above the positioning bottom plate 230 via multiple support columns. The X-axis positioning stepper motor 260 is mounted on the lower surface of the positioning bottom plate 230, and the Y-axis positioning stepper motor 280 is mounted on the upper surface of the positioning bottom plate 230. Multiple Y-axis positioning posts 270 are mounted on two horizontal sides of the positioning bottom plate 230 and electrically connected to the Y-axis positioning stepper motor 280. The positioning top plate 240 has multiple positioning slots 2401. The lower ends of the multiple X-axis positioning posts 250 are mounted on the upper surface of the positioning bottom plate 230, and their upper ends pass through the multiple positioning slots 2401. The X-axis positioning stepper motor 260 is electrically connected to the multiple X-axis positioning posts 250. Multiple flip positions are defined by the X-axis and Y-axis positioning posts. The positioning posts are used for precise positioning of the glass cover and are responsible for adjustment in the X-axis and Y-axis directions, respectively. The X-axis positioning column 250 is responsible for positioning the glass cover along the X-axis (usually left-right). Connected to a stepper motor, the X-axis positioning column moves precisely to ensure accurate alignment of the glass cover along the X-axis. The Y-axis positioning column is responsible for precise positioning of the glass cover along the Y-axis (usually front-back). Controlled by a Y-axis stepper motor, the position of the glass cover in the Y-axis is adjusted to achieve the required precision. During use, the glass cover from the synchronous feeding module is placed on the flipped position of the positioning top plate of the secondary positioning platform. At this point, the position of the glass cover may shift due to vibration or other reasons during the feeding process. Subsequently, the X-axis stepper motor 260 controls the movement of the X-axis positioning column 250, moving it along the X-axis to position the glass cover precisely. After X-axis positioning, the Y-axis stepper motor 280 controls the Y-axis positioning column 270 for fine-tuning along the Y-axis, ensuring accurate adjustment of the glass cover's position in the Y-axis as well. Through precise control of these two axes, the position of the glass cover in both the X and Y axes is accurately corrected, completing the secondary positioning. With the cooperation of the stepper motor and positioning column, the secondary positioning platform can perform position adjustments with micron-level precision.

[0028] Specifically, in one embodiment of this utility model, the AI ​​vision sensor 300 is located above the secondary positioning platform 200 and is used to identify the positioned glass cover plate. Because the AI ​​vision sensor is used to determine the front and back of the 2.5D glass, it can distinguish the front and back of glass with a flatness of less than 0.3, avoiding stacking of glass sheets due to reverse placement and the production of defective products.

[0029] Specifically, in one embodiment of this utility model, the flipping mechanism 400 is mounted on the fixed base plate 600 and located on one side of the secondary positioning platform 200, and is used to flip the glass cover 180° when the AI ​​vision sensor 300 detects that the user face of the glass cover is facing down. Figure 4 The diagram shows a structural schematic of the flipping mechanism of a feeding device for a 2.5D glass cover plate according to an embodiment of the present invention. The flipping mechanism 400 includes a support module 410, a sliding component 420, a lifting module 430, a flipping module 440, and an adsorption module 450. The support module 410 is mounted on the fixed base plate 600 and is the foundation of the entire flipping mechanism, providing stable support. The sliding component 420 is slidably connected to the support module 410. Through its connection with the support module, the sliding component allows the flipping mechanism to slide horizontally, enabling it to move between multiple flipping positions. The lifting module 430 and the flipping module 440 are vertically mounted on the side of the sliding component 420, with the lifting module 430 positioned above the flipping module 440. The adsorption module 450 is horizontally connected to the flipping module 440. The lifting module, located above the sliding assembly and connected to the flipping module, adjusts the position of the adsorption module. Moved up and down by a cylinder, it allows the adsorption module to pick up the glass cover at the appropriate height, ensuring a smooth flipping process. The flipping module, positioned above the lifting module, drives the adsorption module to rotate. Typically controlled by a cylinder, it precisely controls the angle and speed of the glass cover's flipping. The adsorption module, positioned horizontally to the flipping module, is used to adsorb and secure the glass cover. It firmly holds the glass cover with suction cups, preventing it from slipping or falling during the flipping process.

[0030] In use, when the AI ​​vision sensor detects that the glass cover on the secondary positioning platform is facing down, the cylinder of the lifting module drives the suction module to descend 450 degrees, bringing the suction cup into contact with the surface of the glass cover. After the suction module holds the glass cover, the lifting module rises, bringing the glass cover to the position of the flipping module. After the lifting module moves the suction module to the position of the flipping module, the flipping module rotates the suction module via a cylinder, causing the glass cover to flip 180 degrees. After the flip is complete, the sliding component moves the flipping mechanism horizontally, adjusting its position to the next glass cover to be flipped.

[0031] Specifically, in one embodiment of this utility model, the glass transfer mechanism 500 includes a bracket and a lifting module. The lower end of the bracket is fixed to the upper surface of the fixed base plate 600. The lifting module is mounted on the bracket and includes a first lifting component 510 and a second lifting component 520 connected below the first lifting component. The second lifting component 520 of the glass transfer mechanism 500 is used to pick up the flipped glass cover plate and, after all the user sides of the glass cover plates are facing upwards, cooperates with the first lifting component 510 to pick up the glass from the secondary positioning platform 200 and place it on the flatbed washing machine.

[0032] Figure 5 The diagram shows a structural schematic of a glass transfer mechanism for a 2.5D glass cover plate feeding device according to an embodiment of the present invention. The support includes a vertically arranged column 530, a horizontally arranged first crossbeam 540 and second crossbeam 550, and a lifting component connecting plate 560. The lower end of the column 530 is fixed to the fixed base plate 600, ensuring the stability of the entire transfer mechanism through the vertically installed column. The first crossbeam 540 and the second crossbeam 550 are connected to the upper end of the column 530, providing a support surface for other components (such as the lifting component) above them, allowing other components to slide or move freely above them. The lifting component connecting plate 560 is slidably connected to the upper surfaces of the first crossbeam 540 and the second crossbeam 550, providing a foundation for the lifting component to bear weight and move. The first lifting component 510 is installed on the upper surface of the lifting component connecting plate 560, responsible for the overall lifting action, and can be raised and lowered in the longitudinal direction of the support by a cylinder control. The second lifting component 520 is installed on the lower surface of the lifting component connecting plate 560. The bracket also includes a vision sensor mounting plate 570 connected to the lower surface of the first crossbeam 540, and the AI ​​vision sensor 300 is mounted on the vision sensor mounting plate 570.

[0033] Further, in one embodiment of this utility model, the second lifting assembly 520 includes a mounting plate 5201 and multiple lifting units. Each lifting unit includes a lifting cylinder 5202 and an adsorption component 5203. The upper end of the lifting cylinder 5202 is mounted on the lower surface of the mounting plate 5201, and the adsorption component 5203 is mounted on the lower end of the lifting cylinder 5202. Each lifting unit corresponds to a flip position. The upper end of the lifting cylinder 5202 is fixed to the lower surface of the mounting plate 5201, while the lower end is connected to the adsorption component 5203, driving the adsorption component 5203 to move up and down, thereby realizing the gripping and placement of the glass cover. The adsorption component 5203 is typically a suction cup device used to grip and transport the glass cover. It is mounted on the lower end of the lifting cylinder 5202 and firmly adsorbs the glass cover through the principle of negative pressure adsorption. When the adsorption component contacts the glass cover, it provides sufficient suction to stably grip the glass cover, ensuring that it does not slip or fall during transplantation.

[0034] In use, after the flipping mechanism adsorbs and flips the glass, the lifting cylinder of the lifting unit located at the flipping position drives the adsorption component to move downward, and the adsorption component picks up the glass from the flipping mechanism; then the lifting cylinder drives the adsorption component to move upward. If there are still glass covers facing down, the above actions are repeated; finally, only the glass facing up remains on the secondary positioning platform, and the glass is then picked up from the secondary positioning platform by the first lifting component of the glass transfer mechanism and the second lifting component above the glass facing up, and placed together on the flatbed washer.
