Description

Technical Field

[0001] This utility model relates to the field of central control screen production, specifically an automatic loading and unloading device for central control screen production. Background Technology

[0002] The automotive center console screen, installed on the dashboard of the driver's cabin, is the terminal for in-vehicle infotainment and control systems. It serves as the core interactive interface of the smart cockpit, integrating display, touch, and voice control functions, and has become a significant indicator of modern automotive intelligence and connectivity. In the automated loading and unloading process of center console screen production, surface protection and gripping stability are key challenges restricting production efficiency and product yield. Traditional clamping loading and unloading methods apply clamping force to the screen edges using mechanical grippers. However, the glass substrate of center console screens is thin (typically 0.3-2mm) and the frame is fragile. Improper clamping force control can easily cause edge damage, scratches, or breakage, especially for new products such as narrow-bezel and curved screens, leading to a higher defect rate. Therefore, suction cup loading is gradually replacing clamp loading. However, most of the current methods use single-point suction cups for loading and unloading. Although single-point suction cup adsorption avoids contact damage, it has significant drawbacks when dealing with large-sized or wide-area central control screens: the adsorption force of a single suction cup is concentrated in the center of the screen, causing deformation in the edge area due to lack of support. During transportation, the screen is prone to tilting or falling off due to airflow disturbance, mechanical vibration, or changes in acceleration. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an automatic loading and unloading device for the production of central control screens, so as to solve the shortcomings of the prior art.

[0004] The purpose of this utility model is achieved through the following technical solution: an automatic loading and unloading device for central control screen production, including a conveyor and an adjustable loading and unloading mechanism. The conveyor is located within the conveying range of the adjustable loading and unloading mechanism. The adjustable loading and unloading mechanism includes a gantry frame, a slide block, a lifting beam, a central suction cup, and side suction cups. The gantry frame is slidably arranged, and the slide block is slidably installed on the gantry frame. The moving direction of the slide block is perpendicular to the moving direction of the gantry frame on the horizontal plane. The lifting beam is installed on the slide block. A central suction cup and two side suction cups are installed at the bottom of the lifting beam. The two side suction cups are symmetrically arranged about the central suction cup. Both the side suction cups and the lifting beam have the freedom to move in the vertical direction.

[0005] Furthermore, two adjusting sliders are slidably arranged on the lifting beam. The adjusting sliders have the degree of freedom to move along the length of the lifting beam. A cylinder is vertically installed on the top of the adjusting slider, and the telescopic shaft of the cylinder moves through the adjusting slider and connects to the central suction cup.

[0006] Furthermore, a screw groove is provided on the lifting beam, and a bidirectional threaded screw is rotatably installed in the screw groove. Both adjusting sliders are threaded onto the bidirectional threaded screw, and the threads of the two adjusting sliders are in opposite directions. A motor is installed on one side of the lifting beam, and the output shaft of the motor is connected to the bidirectional threaded screw.

[0007] Furthermore, the gantry frame is U-shaped, and ground rails are arranged on both sides of the conveyor. Ground rail slides are slidably adapted on the ground rails, and the two ends of the bottom of the gantry frame are respectively installed on the two ground rail slides.

[0008] Furthermore, each of the ground rails is provided with a rack in parallel, a drive motor is mounted on the ground rail slide, and the output shaft of the drive motor is connected to a gear, which meshes with the rack.

[0010] Furthermore, a main cylinder is vertically mounted at the bottom of the slide block, and the telescopic shaft of the main cylinder is connected to the lifting beam.

[0011] The beneficial effects of this utility model are:

[0012] By replacing the traditional clamping method with a flexible suction cup adsorption, the risk of mechanical claws squeezing and scratching the screen edges is completely eliminated. The central suction cup and the side suction cup work together to dynamically adjust the adsorption point according to the screen size, so that the adsorption force is evenly distributed on the screen surface, reducing the risk of glass substrate breakage or coating damage caused by local stress concentration. The defect rate can be reduced to below 0.1%. Attached Figure Description

Detailed Implementation

[0018] like Figures 1 to 4As shown, an automatic loading and unloading device for central control screen production includes a conveyor 1 and an adjustable loading and unloading mechanism. The conveyor 1 is located within the conveying range of the adjustable loading and unloading mechanism. The adjustable loading and unloading mechanism includes a gantry frame 2, a slide block 3, a lifting beam 4, a central suction cup 5, and side suction cups 6. The gantry frame 2 is slidably arranged, and the slide block 3 is slidably mounted on the gantry frame 2. The moving direction of the slide block 3 is perpendicular to the moving direction of the gantry frame 2 on the horizontal plane. The lifting beam 4 is mounted on the slide block 3. The bottom of the lifting beam 4 is equipped with a central suction cup 5 and two side suction cups 6. The two side suction cups 6 are symmetrically arranged about the central suction cup 5. Both the suction cup 6 and the lifting beam 4 have the freedom to move vertically. After the central control screen is produced, it needs to undergo final quality inspection. The central control screen is transported to the quality inspection workshop by the conveyor 1, and then the central control screen on the conveyor 1 is loaded onto the quality inspection workbench by the adjustable loading and unloading mechanism. The central control screen that has passed quality inspection is unloaded by the adjustable loading and unloading mechanism. Two conveyor belts are arranged at the unloading position of the quality inspection workbench, one for unloading qualified central control screens and the other for unqualified central control screens, thereby realizing automatic loading and unloading of the central control screen. The specific loading and unloading process is as follows: first, the size of the central control screen is adjusted by the central suction cup 5. Regarding the tooling state of the side suction cup 6, when the size of the central control screen is small, the side suction cup 6 moves upward and is in an inactive state; when the size of the central control screen is large, the side suction cup 6 moves downward and is in an active state, so that the hollow suction cup 5 and the side suction cup 6 jointly adsorb the central control screen. After the working state of the suction cups is adjusted, the position of the lifting beam 4 is adjusted by moving the gantry 2 and the slide 3, so that the central control screen on the conveyor 1 is in the working position of the central suction cup 5 and the side suction cup 6. Then the lifting beam 4 moves downward, so that the central suction cup 5 and the side suction cup 6 contact the central control screen, or so that the central suction cup 5 contacts the central control screen. The central control screen is moved to the quality inspection workbench for loading. After quality inspection, the central control screen is unloaded from the workbench in the same way. This process is repeated to achieve automatic loading and unloading of the central control screen. The suction cups, used for flexible contact adsorption, replace the traditional clamping method, completely eliminating the risk of mechanical claws squeezing and scratching the screen edges. The central suction cup 5 and the side suction cups 6 work together, dynamically adjusting the adsorption points according to the screen size to ensure even distribution of adsorption force on the screen surface. This reduces the risk of glass substrate breakage or coating damage caused by localized stress concentration, lowering the defect rate to below 0.1%. In practice, both the central suction cup 5 and the side suction cups 6 are connected to a negative pressure pump via pipes. The negative pressure pump creates negative pressure on the central control screen, which is an existing technology and will not be described further.

[0019] Example 2

[0020] Based on Embodiment 1, two adjusting sliders 7 are slidably arranged on the lifting beam 4. The adjusting sliders 7 have the freedom to move along the length of the lifting beam 4. A cylinder 8 is vertically installed on the top of the adjusting slider 7. The telescopic shaft of the cylinder 8 moves through the adjusting slider 7 and connects to the central suction cup 5. The height of the side suction cup 6 is adjusted by the telescopic movement of the cylinder 8, so that the working state can be adjusted according to the size of the central control screen to adapt to the loading and unloading of central control screens of different sizes.

[0021] Example 3

[0022] Based on Example 2, such as Figures 1 to 4 As shown, the lifting beam 4 has a screw groove 9, and a bidirectional threaded screw 10 is rotatably installed in the screw groove 9. Two adjusting sliders 7 are threaded onto the bidirectional threaded screw 10, and the threads of the two adjusting sliders 7 are opposite in direction. A motor 11 is installed on one side of the lifting beam 4. The output shaft of the motor 11 is connected to the bidirectional threaded screw 10. The motor 11 drives the bidirectional threaded screw 10 to rotate, causing the adjusting sliders 7 to move linearly along the axial direction of the bidirectional threaded screw 10. The two adjusting sliders 7 move in opposite directions, thereby adjusting the distance between the two side suction cups 6. The position of the two side suction cups 6 can be adjusted according to the size of the central control screen, so that the side suction cups 6 can contact the central control screen to perform the adsorption action.

[0023] Example 4

[0024] Based on Embodiment 3, a drive groove 17 is provided on the gantry frame 2, and a lead screw 18 is rotatably installed in the drive groove 17. A lead screw slider is threaded onto the lead screw 18, and the lead screw slider slides and adapts to the drive groove 17. A slide block 3 is installed on the lead screw slider. A stepper motor is installed on the gantry frame, and the output shaft of the stepper motor is connected to the lead screw 18. By driving the lead screw 18 to rotate, the slide block 3 moves linearly along the axial direction of the lead screw 18. A main cylinder 19 is vertically installed at the bottom of the slide block 3. The telescopic shaft of the main cylinder 19 is connected to the lifting beam 4. The height of the lifting beam 4 is adjusted by the telescopic movement of the main cylinder 19, so that the lifting beam 4 drives the central suction cup 5 and the side suction cup 6 to move up and down to complete the loading and unloading operation.

[0025] Example 5

[0026] Based on Embodiment 4, the gantry 2 is U-shaped, and ground rails 12 are arranged on both sides of the conveyor 1. Ground rail slides 13 are slidably fitted on the ground rails 12. The two ends of the bottom of the gantry 2 are respectively installed on the two ground rail slides 13. A rack 14 is arranged in parallel on each ground rail 12. A drive motor 15 is installed on the ground rail slide 13. The output shaft of the drive motor 15 is connected to a gear 16. The gear 16 meshes with the rack 14. The drive motor 15 drives the gear 16 to rotate. Through the cooperation between the gear 16 and the rack 14, the ground rail slide 13 can move on the ground rail 12, thereby realizing the movement of the gantry 2.
