Abstract
Description
Technical Field
[0001] This utility model belongs to the field of glass production line technology, and more specifically, it relates to a robotic arm for glass gripping and barcode scanning. Background Technology
[0002] In the production of display glass, automated production lines widely use robotic arms for handling and manipulation. To improve production efficiency and product quality, these robotic arms need to scan QR codes on the glass for identification and tracking. However, existing robotic arm designs have some problems during the scanning process. Due to the surface color and material of the robotic arm, the QR code easily blends into the background color, resulting in a low scanning success rate. Furthermore, the glare from the robotic arm can interfere with the normal operation of the scanning equipment, further reducing the success rate. These problems not only affect the efficiency of the production line but also increase production costs. In summary, the shortcomings of existing technology are: 1. Low scanning success rate; QR codes easily blend into the background color of the robotic arm. 2. Glare from the robotic arm interferes with the normal operation of the scanning equipment. 3. Production efficiency is affected, and production costs are increased.
[0003] Existing technology includes a device entitled "A Robotic Gripping Device for Glass Production" (publication number CN119681945A), which relates to the field of intelligent manufacturing technology and discloses a robotic gripping device for glass production. This device includes an assembly frame, with a gripping frame and an adjusting frame movably connected to the assembly frame. The adjusting frame is located at the front of the gripping frame, and the initial positions of the gripping frame and the adjusting frame are at the rear of the assembly frame. The gripping frame and the adjusting frame are connected by a traction component. A suction cup assembly is fixedly connected to the bottom of the gripping frame, and a friction plate is provided at the bottom of the adjusting frame. This robotic gripping device for glass production uses the friction between the friction plate and the glass to move the adjusting frame, which in turn pulls the gripping frame. This effectively controls the maximum force generated between the glass and the gripping device, preventing the glass from moving relative to the rollers and reducing the maximum impact force on the gripping device. Furthermore, when placing glass, the gripping frame and the adjusting frame can move to relieve force, effectively preventing excessive pressure on the glass edges. However, this technology does not address the technical problems and solutions of this application. Utility Model Content

[0012] The lower part of the connecting part of the glass Y-direction limiting block is movablely mounted in the second T-shaped groove on the gripper body of the robot arm via a T-shaped block.

[0022] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:
[0023] As attached Figure 1 Appendix Figure 2As shown, this utility model is a robotic arm for glass gripping and barcode scanning. The robotic arm gripper body 1 has a body connecting part 2 at one end, multiple protrusions 3 on one side of the gripper body 1, and multiple protrusions 3 on the other side of the gripper body 1. Each protrusion 3 is equipped with a suction cup 4. A hollow part 5 is provided on the robotic arm gripper body 1, and a QR code area 7 is provided on the display glass 6. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. In this structural design, the body connecting part 2 at one end of the robotic arm gripper body 1 connects the gripper body 1 and the robotic arm body, enabling reliable control of the robotic arm gripper body and allowing it to move within a designated space, reliably gripping and moving the glass. The robotic gripper body 1 has multiple protrusions 3 on one side and multiple protrusions 3 on the other side. These protrusions are perpendicular to the gripper body and are designed to expand the space within the gripper body 1, allowing for the adsorption, gripping, and movement of various types and sizes of display screen glass 1. Each protrusion 3 is equipped with a suction cup 4 for adsorbing the glass. The robotic gripper body 1 has a cutout 5, and the display screen glass 6 has a QR code area 7. The cutout 5 is positioned so that after the robotic gripper grips the glass, the position of the cutout area 7 corresponds to the position of the QR code area 7 on the display screen glass 1. A barcode scanner is located below the robotic gripper body 1 to ensure that the QR code area 7 is fully exposed to the scanner's field of view when scanning is required. This significantly improves the scanning success rate on the display screen glass production line, reduces production interruptions due to scanning failures, and increases the production line's cycle time. The robotic arm for glass gripping and barcode scanning described in this invention has a simple structure, effectively improves the barcode scanning success rate, reduces production interruptions caused by barcode scanning failures, and increases the production line cycle time.
[0024] The robotic gripper body 1 is connected to the production line robotic arm via the body connecting part 2. With this structure, after the robotic gripper body 1 is connected to the production line robotic arm, the robotic arm can control the robotic gripper to move within a set space according to a set trajectory, completing the gripping and movement of glass.
[0025] A barcode scanning device is installed below the gripper body 1 of the robotic arm. When the display screen glass 6 is attached to the suction cup 4, the QR code area 7 of the display screen glass 6 is configured to align with the cutout portion 5. With this configuration, when the gripper body 1 moves past the barcode scanning device, the QR code area 7 can align with the cutout portion 5, and the barcode scanning device can reliably complete the scanning.
[0026] The robotic gripper body 1 is equipped with a glass X-axis limiting block 8 and a glass Y-axis limiting block 9. This structure allows the glass X-axis limiting block 8 and glass Y-axis limiting block 9 to limit the glass from two directions, ensuring accurate relative positioning between the gripped glass and the robotic gripper body. This reliably ensures that the QR code area 7 of the display screen glass 6 is aligned with the cutout portion 5, facilitating accurate scanning by the scanning device below the robotic gripper body 1.
[0027] The lower part of the glass X-axis limiting block 8 is movably mounted in the first T-slot on the robotic gripper body 1 via a T-shaped block, with the T-slot positioned along the X-axis. With this structure, the position of the glass X-axis limiting block 8 can be adjusted in the X-axis. After adjustment to the correct position for a specific type and size of glass, tightening the positioning screws on the glass X-axis limiting block 8 fixes the positions of the glass X-axis limiting block 8 and the robotic gripper body 1, preventing easy movement.
[0028] The lower part of the glass Y-axis limiting block 9 is movably engaged in the second T-groove on the robotic gripper body 1 via a T-shaped block, with the T-groove positioned along the Y-axis. The glass Y-axis limiting block 9 includes a connecting part 10 and a limiting part 11, which are configured in an L-shape. The lower part of the connecting part 10 of the glass Y-axis limiting block 9 is movably engaged in the second T-groove on the robotic gripper body 1 via a T-shaped block. With this structure, the position of the glass Y-axis limiting block 9 can be adjusted in the Y-axis. After adjustment for a specific model and size of glass, tightening the positioning screws on the glass Y-axis limiting block 9 fixes the positions of the glass Y-axis limiting block 9 and the robotic gripper body 1, preventing easy movement.
[0029] Each suction cup 4 on the protruding part 3 is connected to a vacuum branch pipe, and each vacuum branch pipe is connected to a vacuum main pipe on the gripper body 1 of the robotic arm. The vacuum main pipe is connected to a vacuum pump through a hose. With the above structure, the suction cups effectively improve the adsorption reliability when adsorbing glass through a vacuum supply.
[0030] An illumination bulb is installed at the lower part of the robotic gripper body 1. This structure, through the illumination bulb, provides a uniform lighting environment for the barcode scanning device, reducing the impact of shadows and reflections on scanning, improving the recognition capability of the barcode scanning device, and further increasing the success rate of barcode scanning.
[0031] The robotic arm for glass gripping and scanning described in this utility model has the following structural configuration: One end of the robotic arm gripper body 1 has a body connecting part 2, which connects the robotic arm gripper body 1 and the robotic arm body, enabling reliable control of the robotic arm gripper body and allowing it to move within a designated space, reliably gripping and moving the glass. Multiple protrusions 3 are provided on one side and the other side of the robotic arm gripper body 1. These protrusions are perpendicular to the robotic arm gripper body, expanding the space of the robotic arm gripper body 1. This allows for the adsorption, gripping, and movement of display screen glass 1 of various models and sizes. Each protrusion 3 is equipped with a suction cup 4 for adsorbing the glass. A hollow section 5 is provided on the robotic arm gripper body 1, and a QR code area 7 is provided on the display screen glass 6. The hollow section is positioned so that after the robotic arm grips the glass, the position of the hollow section area 7 corresponds to the position of the QR code area 7 on the display screen glass 1. A barcode scanner is installed below the robotic gripper body 1 to ensure that the QR code area 7 is fully exposed in the scanning device's field of view when the glass needs to be scanned. This significantly improves the scanning success rate on the display glass production line, reduces production interruptions caused by scanning failures, and increases the production line's cycle time.
