Description

Technical Field

[0001] This utility model belongs to the field of semiconductor product technology, and more specifically, it relates to a rotating platform transfer mechanism. Background Technology

[0002] In automated manufacturing, especially in LCD panel, semiconductor, or electronic component production lines, it is often necessary to transfer and rotate product frames between multiple workstations at high speed and with high precision. Existing transfer mechanisms typically employ traditional belt, lead screw, or cylinder drive methods, which have some inherent drawbacks. For example, belt drives are prone to slippage and tension, leading to unstable positioning accuracy; lead screw drives are susceptible to wear and thermal deformation at high speeds, resulting in high maintenance costs; and cylinder drives are limited by their control precision and speed, making it difficult to meet the extremely high requirements of modern production lines for cycle time and efficiency.

[0003] Furthermore, existing rotary positioning mechanisms often rely on a single sensor for position feedback. At high speeds, these mechanisms are prone to positioning errors due to false signals or blind spots, leading to collisions or product damage, severely impacting production efficiency and equipment stability. Therefore, the industry urgently needs a rotary transfer mechanism that is stable, accurate in positioning, highly efficient, and reliable to address these technical problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a rotating platform transplanting mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a rotating platform transplanting mechanism, characterized in that it includes a product frame tray, a linear drive module, a rotary drive module, and a detection system;

[0006] The linear drive module includes two parallel slide rails and a first linear motor actuator and a second linear motor actuator mounted on the slide rails. The output ends of the first linear motor actuator and the second linear motor actuator are fixedly connected to the bottom sides of the product frame tray, and are used to drive the product frame tray to move linearly along the axial direction of the slide rails.

[0007] The rotary drive module includes a rotary motor and a base fixedly connected to the body of the rotary motor. The output shaft of the rotary motor is connected to the center bottom of the product frame tray through a transmission mechanism, and is used to drive the product frame tray to rotate around its central axis.

[0008] The detection system includes a product frame detector, which is installed on the side or above the product frame tray to detect whether the product frame is placed in a predetermined position on the tray. It also includes a first rotation detector and a second rotation detector, which are symmetrically installed on the bottom sides of the product frame tray to detect the rotation angle and provide redundant signal verification.

[0009] The linear drive module and the rotary drive module work together to achieve linear transfer and precise positioning rotation of the product frame.

[0010] Preferably, each slide rail of the linear drive module is connected to a tank chain at both ends, and the tank chain houses and protects the cables connected to the first linear motor actuator and the second linear motor actuator.

[0011] Preferably, the installation positions of the first rotation detector and the second rotation detector differ by a specific angle, which is used to detect different phases of the rotating platform and jointly realize full-process monitoring of the rotation angle and origin positioning.

[0012] Preferably, the transmission mechanism includes a reducer located on the output shaft of the rotary motor, a turntable bearing located on the output shaft of the reducer, and the upper surface of the turntable bearing is fixedly connected to the bottom surface of the product frame tray.

[0013] This utility model provides a rotating platform transplanting mechanism, which has the following beneficial effects:

[0014] 1. Stable operation and strong load-bearing capacity: It adopts two sets of linear motors for parallel drive, and is supplemented by multiple parallel slide rails to form a stable linear drive module. This symmetrical layout effectively avoids the problems of off-center load, jamming and shaking that may occur in single-point drive, ensuring the stability of the product frame pallet during high-speed linear motion and improving the rigidity and load capacity of the mechanism.

[0015] 2. High positioning accuracy: The rotary positioning system adopts a dual detection design, namely a first rotary detector and a second rotary detector. The two sensors verify each other, which not only realizes accurate monitoring of the rotation angle throughout the process, but also constitutes a redundant backup system. This effectively prevents positioning errors or mechanical collisions caused by false signals or failures of a single sensor, greatly improving the reliability and safety of the equipment.

[0016] 3. Significantly improved work efficiency: The linear motor has the characteristics of high speed and high acceleration. Combined with stable and reliable rotary positioning, the cycle time of the entire "transfer-positioning-rotation-discharging" process is greatly shortened. The detection system responds quickly and ensures seamless process connection, thereby improving overall production efficiency and equipment capacity. Attached Figure Description

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figures 1 to 2 This utility model provides a technical solution: a rotating platform transfer mechanism, including a product frame tray 1, a linear drive module, a rotary drive module, and a detection system.

[0024] The linear drive module includes two parallel slide rails 8 and a first linear motor actuator 2 and a second linear motor actuator 3 mounted on the slide rails 8. The output ends of the first linear motor actuator 2 and the second linear motor actuator 3 are fixedly connected to the bottom sides of the product frame tray 1, and are used to drive the product frame tray 1 to move linearly along the axial direction of the slide rails 8. Each slide rail 8 of the linear drive module is connected to a tank chain 9 at both ends. The tank chain 9 houses and protects the cables connected to the first linear motor actuator 2 and the second linear motor actuator 3.

[0025] The rotation drive module includes a rotation motor 7 and a base fixedly connected to the body of the rotation motor 7. The output shaft of the rotation motor 7 is connected to the center bottom of the product frame tray 1 through a transmission mechanism, and is used to drive the product frame tray 1 to rotate around its central axis.

[0026] The transmission mechanism includes a reducer located on the output shaft of the rotary motor 7, and a turntable bearing located on the output shaft of the reducer. The upper surface of the turntable bearing is fixedly connected to the bottom surface of the product frame tray 1.

[0027] The detection system includes a product frame detector 4, which is installed on the side or above the product frame tray 1 to detect whether the product frame is placed in a predetermined position on the tray. It also includes a first rotation detector 5 and a second rotation detector 6, which are symmetrically installed on the bottom sides of the product frame tray 1 to detect the rotation angle and provide redundant signal verification. The installation positions of the first rotation detector and the second rotation detector 6 differ by a specific angle to detect different phases of the rotating platform, so as to achieve full-process monitoring of the rotation angle and origin positioning.

[0028] The linear drive module and the rotary drive module work together to achieve linear transfer and precise positioning rotation of the product frame.

[0029] The specific usage and function of this embodiment are as follows:

[0030] 1. Initial state: The mechanism is in the initial position (such as the starting position in the straight line direction, or the 0° position in the rotation angle).

[0031] 2. Frame Placement Detection: The upstream device transports the product frame to the product frame tray 1 of this facility. The product frame detection sensor detects that the frame has been accurately placed and sends a ready signal.

[0032] 3. Linear transfer: After receiving the signal, the control system moves the two linear motors synchronously, driving the entire pallet and product frame to move at high speed and smoothly along the slide rail 8 to the target workstation.

[0033] 4. Precise Positioning Rotation: Upon reaching the target position, the rotary motor 7 starts, driving the tray and product frame to rotate to a preset angle. During this process, the first rotation detector 5 and the second rotation detector 6 monitor the rotation angle in real time. When approaching the target angle, the motor slows down; when the precise angle is reached, both sensors jointly confirm and send a signal to the control system, the motor stops and locks, ensuring error-free positioning. One rotation detector is used for primary positioning, and the other for verification and backup, preventing angle errors caused by a single sensor failure, greatly improving reliability.

[0034] 5. Frame Unloading and Return: The downstream robot or device removes the rotated and positioned product frame. Subsequently, the mechanism rotates in the opposite direction to reset as instructed, and drives the linear motor mover back to the initial position, waiting to receive the next product frame and begin a new cycle.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
