Description

Technical Field

[0001] This utility model relates to the field of semiconductor dry pack packaging and testing, and more particularly to a tray disk stable transfer device. Background Technology

[0002] In the field of semiconductor manufacturing and packaging (Dry Pack), trays are an important packaging tool widely used for vacuum-sealed packaging of microelectronic products such as chips. This packaging method, with its high efficiency and safety features, plays a crucial role in protecting chips from external contamination and mechanical damage. However, current tray packaging and transportation processes mainly rely on traditional conveyor lines. While this method meets the needs of automated production to some extent, it still faces many challenges in practical applications.

[0003] First, due to limitations in conveyor speed, precision, and stability, trays often experience inaccurate positioning during transport. This positioning error not only causes relative shifts between trays but can also lead to misalignment between multiple layers of trays. In high-speed, high-density production environments, this misalignment problem is particularly pronounced, posing a serious threat to production efficiency and product quality. Second, tray misalignment can have even more severe consequences, significantly increasing the risk of chip movement and damage within the tray. Since chips are typically precisely placed in specific positions on the tray and rely on the tray's structure and materials for protection and support, misalignment can cause chips to move under unstable forces, colliding with the tray or adjacent chips and resulting in damage.

[0004] Traditional tray transfer methods are no longer sufficient to meet the increasing precision requirements, and there is an urgent need for a more stable and accurate tray transfer device to ensure the smooth progress of chip packaging and testing. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a tray stable transfer device. The automated design of this device makes the tray transfer process more efficient and faster, reduces manual intervention and equipment failure handling time, and improves overall production efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a tray disk stabilization and transfer device, comprising...

[0007] The support platform is equipped with several slots for placing trays;

[0008] A clamping mechanism is located below the support platform and is used to clamp the tray.

[0009] The lifting drive assembly is connected to the clamping mechanism to lift and clamp the tray.

[0010] The linear lateral movement drive assembly is connected to the lifting drive assembly and drives the lifting drive assembly and clamping mechanism to move along the direction of the support platform. When the tray moves above the placement slot of the support platform, the lifting drive assembly drives the tray to descend and fall into the placement slot, and the clamping mechanism releases the tray. Then the linear lateral movement drive assembly drives the lifting drive assembly and clamping mechanism to return to their original positions.

[0011] Furthermore, limit baffles are also provided on both sides of the support platform, with the limit baffles located on both sides of the Tray disk.

[0012] Furthermore, it also includes a horizontal fixed plate, a lifting fixed plate, a guide rod, and a linear bearing. The horizontal fixed plate is connected to the output end of the linear lateral movement drive assembly, and the lifting drive assembly is mounted on the horizontal fixed plate. The output end of the lifting drive assembly is connected to the lifting fixed plate. One end of the guide rod is connected to the bottom of the lifting fixed plate, and the other end passes through the horizontal fixed plate via the linear bearing. The lifting drive assembly drives the lifting fixed plate to move up and down, while the guide rod moves synchronously.

[0013] Furthermore, it also includes a mounting base, wherein the mounting base is configured to assemble the transverse slot of the linear transverse drive component, wherein transverse slide rails are provided on both sides of the top of the transverse slot, and the bottom sides of the horizontal fixing plate are slidably mounted on the transverse slide rails by sliders.

[0014] Furthermore, the mounting base is provided with support blocks on both outer side walls, and a support column is mounted on the support block. The other end of the support column is mounted to the bottom of the support platform.

[0015] The beneficial effects of this invention are as follows: Through the design of the clamping mechanism, the device can effectively clamp the tray during transport, preventing it from shaking or slipping during movement, thus significantly improving transport stability. The combined use of the linear traverse drive assembly and the lifting drive assembly allows for precise control of the tray's position on the support platform. When the tray is moved above the designated placement slot, the release of the clamping mechanism and the descent of the lifting drive assembly ensure that the tray accurately falls into the designated slot, avoiding misalignment that may occur in traditional transport methods.

[0016] Meanwhile, because the device can stably and accurately transfer trays, it reduces the risk of chip misalignment or shaking during transport, thus protecting the safety and integrity of the chips. The automated design of this device makes the tray transfer process more efficient and stable, reducing manual intervention and equipment malfunction handling time, and improving overall production efficiency.

Detailed Implementation

[0021] Please see Figure 1-3 As shown, this utility model relates to a stable transfer device for a tray 6, including a hollow support platform 1 with several placement slots 11 for placing trays 6; a clamping mechanism 4, located below the support platform 1 and used to clamp the trays 6; a lifting drive assembly 5, which is driven to the clamping mechanism 4 to lift and clamp the trays 6; and a linear lateral movement drive assembly 3, which is driven to the lifting drive assembly 5 and drives the lifting drive assembly 5 and the clamping mechanism 4 to move along the direction of the support platform 1. When the tray 6 moves to a placement slot 11 above a preset position on the support platform 1, the lifting drive assembly 5 lowers the tray 6 and causes it to fall into the designated placement slot 11. The clamping mechanism 4 releases the tray 6, and then the linear lateral movement drive assembly 3 drives the lifting drive assembly 5 and the clamping mechanism 4 back along the original path.

[0022] Its beneficial effects are as follows: Through the design of the clamping mechanism 4, the device can effectively clamp the tray 6 during the transport process, preventing it from shaking or slipping during movement, thereby significantly improving the stability of the transport. The combined use of the linear transverse drive assembly 3 and the lifting drive assembly 5 can precisely control the position movement of the tray 6 on the support platform 1. When the tray 6 is moved above the designated placement slot 11, the release of the clamping mechanism 4 and the descent of the lifting drive assembly 5 allow the tray 6 to fall accurately into the designated slot, avoiding the misalignment that may occur in traditional transport methods.

[0023] Meanwhile, because the device can stably and accurately transfer Tray 6, it reduces the risk of chip misalignment or shaking during transport, thus protecting the chip's safety and integrity. The automated design of this device makes the Tray 6 transfer process more efficient and faster, reducing manual intervention and equipment malfunction handling time, and improving overall production efficiency.

[0024] Furthermore, limit baffles 12 are provided on both sides of the support platform 1, with the limit baffles 12 located on both sides of the Tray disk 6.

[0025] Limiting baffles 12 are located on both sides of the tray 6, and their main function is to prevent the tray 6 from moving laterally during transport. In automated or mechanized transport systems, even if the clamping mechanism 4 can firmly hold the tray 6, slight lateral displacement may still occur during high-speed movement or when subjected to external impact. The presence of limiting baffles 12 can effectively limit this displacement, ensuring that the tray 6 always remains on the predetermined track. In addition to preventing lateral displacement, limiting baffles 12 can also improve the positioning accuracy of the tray 6 to a certain extent. When the tray 6 is moved to the designated position, the limiting baffles 12 can serve as a physical reference point, helping the clamping mechanism 4 and the lifting drive assembly 5 to more accurately determine the position of the tray 6. This helps reduce errors caused by inaccurate position judgment and improves the accuracy and reliability of the entire transfer process. In high-speed or complex transport environments, the tray 6 may be damaged by collisions or friction, which may affect the chips inside. The presence of limiting baffles 12 can reduce direct contact between the tray 6 and the support platform 1 or other components, reducing the risk of damage. At the same time, it can also prevent the chip from moving inside the Tray 6 due to shaking during movement, thereby protecting the safety and integrity of the chip.

[0026] Further discussion includes a horizontal fixed plate 24, a lifting fixed plate 51, a guide rod 52, and a linear bearing 53. The horizontal fixed plate 24 is connected to the output end of the linear transverse drive assembly 3, and the lifting drive assembly 5 is mounted on the horizontal fixed plate 24. The output end of the lifting drive assembly 5 is connected to the lifting fixed plate 51. One end of the guide rod 52 is connected to the bottom of the lifting fixed plate 51, and the other end passes through the linear bearing 53 and through the horizontal fixed plate 24. The lifting drive assembly 5 drives the lifting fixed plate 51 to move up and down, while the guide rod 52 moves synchronously.

[0027] The horizontal fixed plate 24 serves as the supporting foundation for the entire lifting drive assembly 5 and is tightly connected to the output end of the linear transverse drive assembly 3, ensuring the stability of the lifting drive assembly 5 during movement. The lifting fixed plate 51 is connected through the output end of the lifting drive assembly 5 and is used to support the clamping mechanism 4. This double-layer fixed plate design increases the strength and rigidity of the structure, making the entire lifting process smoother.

[0028] Furthermore, the combination of guide rod 52 and linear bearing 53 serves a guiding and positioning function. One end of guide rod 52 is connected to the bottom of lifting fixed plate 51, and the other end passes through horizontal fixed plate 24 and is fixed by linear bearing 53. When the lifting drive assembly 5 is working, it drives the lifting fixed plate 51 to move up and down along the direction of guide rod 52. The presence of linear bearing 53 reduces friction and resistance, making the movement process smoother. At the same time, the precise cooperation between guide rod 52 and linear bearing 53 also ensures the stability and accuracy of lifting fixed plate 51 during movement.

[0029] Further discussion includes a mounting base 2, which is designed to assemble the horizontal slot 21 of the linear transverse drive assembly 3. Horizontal slide rails are provided on both sides of the top of the horizontal slot 21, and the bottom sides of the horizontal fixing plate 24 are slidably mounted on the horizontal slide rails via sliders 25. The mounting base 2, as the foundation of the entire device, provides a stable support platform 1. It is made of robust materials and has sufficient load-bearing capacity and stability to withstand the weight and forces generated during operation of components such as the linear transverse drive assembly 3, the lifting drive assembly 5, the clamping mechanism 4, and the tray 6. The mounting base 2 is specially designed with a horizontal slot 21 for assembling the linear transverse drive assembly 3. This design allows the linear transverse drive assembly 3 to be securely mounted on the base, while facilitating subsequent maintenance and replacement. The dimensions and shape of the horizontal slot 21 are designed according to the specific requirements of the linear transverse drive assembly 3 to ensure a tight fit and normal operation. The top two sides of the horizontal slot 21 are provided with horizontal slide rails, while the bottom two sides of the horizontal fixing plate 24 are slidably mounted on the horizontal slide rails via sliders 25. This design achieves a gapless connection and precise guidance between the horizontal fixing plate 24 and the linear transverse drive assembly 3. When the linear transverse drive assembly 3 is working, it drives the horizontal fixing plate 24 to move laterally along the horizontal slide rails. The smoothness and straightness of the horizontal slide rails ensure the stability and accuracy of the movement process, reducing errors caused by friction or vibration. The combined design of the mounting base 2, horizontal slot 21, horizontal slide rails, and sliders 25 not only provides stable support and precise guidance but also enhances the load-bearing capacity and stability of the entire device. When the tray 6 and its related components move laterally, this design effectively reduces vibration and shaking, ensuring that the tray 6 can move smoothly to the designated position.

[0030] Further discussion includes that the mounting base 2 has support blocks 22 on its two outer side walls, and a support column 23 is mounted on the support block 22. The other end of the support column 23 is mounted to the bottom of the support platform 1.

[0031] The support block 22 serves as a bridge connecting the mounting base 2 and the support column 23. Its location on both sides of the mounting base 2 not only increases the number of connection points but also distributes the force transmitted from the support column 23, thereby enhancing the structural stability of the entire device. This design allows the device to maintain a more stable posture when bearing the weight of the Tray disk 6 and its internal chips, reducing swaying caused by vibration or external forces. The support column 23 is connected to the mounting base 2 via the support block 22, and its other end is fitted to the bottom of the support platform 1. This design makes the support column 23 one of the important support structures of the support platform 1, sharing the weight of the Tray disk 6 and its related components with the mounting base 2. The support column 23 is typically made of robust materials with high strength and rigidity, ensuring that the support platform 1 will not deform or sink when bearing heavy loads. The design of the support block 22 and the support column 23 also considers the optimization of spatial layout. By mounting the support column 23 onto the support block 22 and assembling it with the bottom of the support platform 1, the overall structure of the device is made more compact, and unnecessary material waste and space occupation are reduced. This design helps to achieve efficient and stable transfer of the Tray disk 6 within a limited space.

[0032] The following describes the complete working process of the overall solution:

[0033] Initialization state: Tray 6 stable transfer device is in the initial position, clamping mechanism 4 is located below support platform 1 and in the initial state (may be retracted or released), lifting drive component 5 and linear lateral drive component 3 are both in standby state.

[0034] Initial lifting: Upon receiving the transfer command, the lifting drive assembly 5 is activated first. Guided by the guide rod 52 and the linear bearing 53, it drives the lifting fixing plate 51 and the clamping mechanism 4 to move upward to a height close to but not yet in contact with the bottom of the tray 6.

[0035] Tray 6 clamping: When the clamping mechanism 4 is raised to the appropriate position, the clamping mechanism 4 is activated to clamp the Tray 6, ensuring that the Tray 6 is firmly clamped.

[0036] Tray 6 is further lifted: After Tray 6 is firmly clamped, the lifting drive assembly 5 continues to work, driving the lifting fixing plate 51 and clamping mechanism 4 to continue to move upward, completely lifting Tray 6 and separating it from the original support surface.

[0037] Tray 6 lateral movement: After Tray 6 is fully lifted, the linear lateral movement drive component 3 is activated and moves along the direction of the support platform 1, driving the entire clamped Tray 6 to move above the designated placement slot 11.

[0038] Tray 6 lowering: After Tray 6 moves above the designated position, the lifting drive component 5 reverses its operation, driving the clamping mechanism 4 and Tray 6 to move downwards until Tray 6 contacts the designated placement slot 11 on the support platform 1.

[0039] Reset and Standby: Clamping mechanism 4 is released, and linear transverse drive assembly 3 drives lifting drive assembly 5 and clamping mechanism 4 to reset to their initial positions, ready for the next transfer operation. The entire transfer device returns to standby state, waiting for the next transfer command.

Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
