Description

Technical fields:

[0001] This invention relates to the field of industrial automation, and in particular to a high-precision bidirectional pick-and-place integrated motion mechanism. Background technology:

[0002] Currently, LCD panel display aging furnaces primarily rely on multiple fixtures placed into the furnace for lighting and testing. This involves long product aging times, a large number of fixtures (approximately 388 fixtures per unit), and significant weight (each fixture plus the product weighs approximately 25 kg). This results in several drawbacks, including difficulties in handling: 1. Due to the stacking of fixtures in the aging furnace (up to 24 layers), with fixtures placed on both sides of the furnace, the fixtures must face one direction depending on the flow of materials on the production line. This prevents the design of a retractable fork for picking up and placing materials from both sides. 2. The limited handling space in the middle of the production line necessitates a fork extension arm (extending at least twice its own length). When extending to pick up fixtures, insufficient fork structural strength can cause the carrier to collapse, potentially leading to impacts with the furnace body and insufficient lighting rate. Therefore, a more practical fork carrier needs to be developed to achieve fast and stable operation.

[0003] Typically, equipment requires multiple workstations to collaborate to achieve the target based on the customer's cycle time requirements. However, achieving this target usually involves a single-workstation array arrangement, which sacrifices equipment size and complicates the equipment handling structure. This results in high equipment costs and large equipment sizes. Summary of the Invention:

[0004] To address the shortcomings of existing technologies, this invention provides a method for handling jigs and similar products within aging furnaces. It offers high precision and fully automated lighting and programming functions. The bidirectional pick-and-place mechanism reduces equipment size and investment in testing equipment. It primarily enables multi-station applications on equipment of the same size, eliminating jig sagging caused by the extension of the toothed fork during jig handling. This ensures a high lighting rate and reduces cycle time losses during loading and unloading, lowering manufacturing costs and achieving higher efficiency. It is compatible with universal jig platforms ranging from 550*950mm to 550mm*1500mm.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-precision bidirectional pick-and-place integrated motion mechanism includes a rotating support platform, a speed-multiplying moving mechanism, and a moving fork arm platform. A drive mechanism is installed on the rotating support platform to drive the speed-multiplying moving mechanism to slide on the rotating support platform. The moving fork arm platform is located on the speed-multiplying moving mechanism. A fixed component is installed on the rotating support platform, and a pair of driven synchronous pulleys are installed at the lower end of the moving fork arm platform. A second-stage synchronous belt on the driven synchronous pulleys is fixedly connected to the fixed component, and the synchronous belt drives the moving fork arm platform to slide on the speed-multiplying moving mechanism.

[0007] As a further embodiment of the present invention, the driving mechanism includes a servo motor and a first-stage synchronous belt, wherein the servo motor is connected to the first-stage synchronous belt via a reducer to drive the speed-multiplying moving mechanism.

[0008] As a further embodiment of the present invention, a first slide rail is provided on the rotating support platform, and the speed-multiplying movement mechanism is driven by a servo motor to slide on the first slide rail.

[0009] As a further embodiment of the present invention, the speed-multiplying moving mechanism is provided with a second slide rail, and a slider is provided on the second slide rail. The moving fork arm platform is connected to the second slide rail through the slider.

[0010] As a further embodiment of the present invention, the pair of driven synchronous wheels includes a first driven synchronous wheel and a second driven synchronous wheel. The first driven synchronous wheel is located at the lower end of the speed-multiplying moving mechanism, and the second driven synchronous wheel is connected to the lower end of the moving fork arm platform through a fixed structure. The pair of driven synchronous wheels drives the moving fork arm platform to slide on the speed-multiplying moving mechanism.

[0011] As a further embodiment of the present invention, a toothed fork is provided on each side of the movable fork arm platform, and a pin is provided on the toothed fork for positioning the fixture, and a suction cup is also provided for adsorbing the fixture.

[0012] As a further embodiment of the present invention, a front-reflecting optical fiber, an upper-reflecting optical fiber, and a lower-reflecting optical fiber are respectively installed on both sides of the end of the tooth fork.

[0013] The present invention has the following beneficial effects:

[0014] 1. The high-precision bidirectional pick-and-place integrated motion mechanism provided by the present invention uses a servo motor to move the Y-axis and a primary synchronous belt to drive the speed-doubled moving mechanism on the slide rail forward. At the same time, the two guide rails connected to the speed-doubled moving mechanism are connected to the moving fork arm platform, and the synchronous belt in the middle is connected to the moving fork arm platform to move forward at a speed of 1:2, realizing the function of fast and long-stroke pick-and-place of materials.

[0015] 2. In this invention, front-reflecting optical fibers, upper-reflecting optical fibers, and lower-reflecting optical fibers are respectively installed on both sides of the end of the toothed fork to sense the possibility of collision when the toothed fork malfunctions in three directions during operation. Pin positioning fixtures are installed on both sides of the toothed fork to ensure the illumination rate. Suction cups are used to adhere the fixtures, ensuring their stability during movement.

[0016] 3. This invention can meet the needs of large-size jigs: it is compatible with a universal platform for jigs ranging from 550*950mm to 550mm*1500mm. It achieves high-load handling of 25-35kg. It enables high-precision bidirectional material handling and accurate positioning. After removing the jig, the fork lowers and releases material, resulting in minimal fork rebound under no-load conditions. The fork rebound difference is only 5mm when extended and under 25kg load. It achieves a compact overall layout, and the mechanism is suitable for various lighting methods and applications on different equipment.

[0017] 4. The high-precision bidirectional pick-and-place integrated motion mechanism of the present invention is ingeniously designed. Driven by a servo motor, it can extend the moving fork arm platform and achieve a 1:2 speed ratio between the driving of the first-stage synchronous belt and the moving fork arm platform.

Thus, by driving with a servo motor, the movable fork arm platform can be extended, and the speed of the first-stage synchronous belt movement and the movable fork arm platform can be matched at a 1:2 ratio.

[0029] Further preferably, the drive mechanism includes a servo motor 3 and a first-stage synchronous belt 4. The servo motor 3 is connected to the first-stage synchronous belt 4 through a reducer to drive the speed-multiplying moving mechanism 200 to move. Furthermore, a first slide rail 5 is provided on the rotating support platform 100. The speed-multiplying moving mechanism 200 is driven by the servo motor to slide on the first slide rail 5, thereby realizing the first-stage drive.

[0032] Reference Figures 1-4As shown, this invention provides a high-precision bidirectional pick-and-place integrated motion mechanism, including a rotating support platform 100, a speed-multiplying moving mechanism 200, and a movable fork arm platform 300. A drive mechanism is provided on the rotating support platform 100 to drive the speed-multiplying moving mechanism 200 to slide on the rotating support platform 100, achieving the first stage of motion. The movable fork arm platform 300 is located on the speed-multiplying moving mechanism 200. A fixing member 1 is provided on the rotating support platform 100. A pair of driven synchronous wheels are provided at the lower end of the movable fork arm platform 300. A second-stage synchronous belt 2 on the driven synchronous wheels is fixedly connected to the fixing member 1. The second-stage synchronous belt 2 drives the movable fork arm platform 300 to slide on the speed-multiplying moving mechanism 200, achieving the second stage of motion. Thus, by driving with a servo motor, the movable fork arm platform can be extended, and the speed of the first-stage synchronous belt movement and the movable fork arm platform can be matched at a 1:2 ratio.

[0033] Further preferably, the drive mechanism includes a servo motor 3 and a first-stage synchronous belt 4. The servo motor 3 is connected to the first-stage synchronous belt 4 through a reducer to drive the speed-multiplying moving mechanism 200 to move. Furthermore, a first slide rail 5 is provided on the rotating support platform 100.

Specifically, it is installed at the lower end of the double-speed moving mechanism 200 through the first driven synchronous wheel mounting structure 10. The second driven synchronous wheel 9 is connected to the lower end of the moving fork arm platform 300 through the fixing structure 11. The moving fork arm platform slides on the double-speed moving mechanism through a pair of driven synchronous wheels. The specific working method is as follows: the servo motor drives the double-speed moving mechanism to move on the first slide rail. At this time, since the second-level synchronous belt 2 is fixedly connected to the fixing part 1, it drives the movement of the second-level synchronous belt 2, which in turn drives the moving fork arm platform to slide on the second slide rail 6. Thus, the double-speed moving mechanism on the slide rail is driven forward by the servo motor moving the Y-axis first-level synchronous belt. At the same time, the two guide rails connecting the double-speed moving mechanism are connected to the moving fork arm platform, and the synchronous belt in the middle is connected to the moving fork arm platform to move forward at a speed of 1:2, realizing the function of fast and long-stroke picking and placing of materials.

Pins 350 are installed on both sides of the fork to provide positioning fixtures and ensure illumination rate. Suction cups 340 are used to adhere the fixtures and ensure their stability during movement.

[0037] This invention enables multi-station applications on equipment of the same size, eliminating the carrier sagging phenomenon caused by the extension of the toothed fork during jig loading and unloading. It ensures high illumination rate and reduces cycle time loss during loading and unloading, lowering equipment manufacturing costs and achieving higher efficiency. It is compatible with universal jigs ranging from 550*950mm to 550mm*1500mm; achieving high-precision bidirectional loading and unloading with accurate alignment.
