Description

Technical Field

[0001] This utility model relates to the field of semiconductor device manufacturing technology, and in particular to a tray that facilitates the loading and unloading of semiconductor devices. Background Technology

[0002] In the production and testing of semiconductor devices, in order to improve production efficiency, trays are needed to position multiple semiconductor devices and to facilitate the transfer of semiconductor devices on the assembly line.

[0003] To facilitate the miniaturization of semiconductor devices and improve safety during the transfer process, positioning slots need to be designed on the trays to place the semiconductor devices into them, thus preventing the devices from shaking or flying off. However, the design of the positioning slots results in the semiconductor devices being partially hidden, which affects the loading and unloading of semiconductor devices and hinders manual or robotic gripping of them. Improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a tray that facilitates the loading and unloading of semiconductor devices, enabling the positioning of semiconductor devices without affecting their loading and unloading.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A tray for facilitating the loading and unloading of semiconductor devices includes: a tray base plate, a pad plate, a floating plate, and a cover plate. The tray base plate is suspended above the pad plate. The floating plate is disposed between the tray base plate and the pad plate. A pin seat is provided on the pad plate. A rotating shaft is provided on the pin seat. A rotating cylinder supporting the floating plate is eccentrically disposed on the rotating shaft. Semiconductor device positioning seats are spaced apart on the tray base plate. The cover plate is suspended above the tray base plate and is provided with a protective sleeve concentrically fitted outside the semiconductor device positioning seats. A support rod is provided on the floating plate, extending upward through the tray base plate and connecting to the cover plate.

[0007] The pad is provided with columns that support the tray base plate at intervals.

[0008] The outer wall of the rotating cylinder has a recessed platform surface on the side away from the rotating shaft.

[0009] The tray base plate is provided with a handle.

[0010] One end of the rotating shaft is provided with a radially extending handle.

[0011] The semiconductor device positioning seat has a pin clearance groove recessed on its top surface.

[0012] An elastic element is provided between the tray base plate and the floating plate.

[0013] The elastic element is a spring, which is sleeved on the support rod.

[0014] The beneficial effects of this utility model are as follows: A tray that facilitates the loading and unloading of semiconductor devices can place semiconductor devices on a semiconductor device positioning seat and use a protective sleeve to limit the semiconductor devices around their perimeter, improving the positioning effect and stability during the transfer process. When loading and unloading semiconductor devices are required, the rotating shaft is rotated 180° manually or by a robotic arm, causing the floating plate and cover plate to descend. The protective sleeve then descends to release the limitation on the semiconductor devices around their perimeter, facilitating the loading and unloading of semiconductor devices. The operation is simple. Attached Figure Description

[0019] A tray for facilitating the loading and unloading of semiconductor devices includes: a tray base plate 1, a pad plate 2, a floating plate 5, and a cover plate 3. The tray base plate 1 is suspended above the pad plate 2. In this embodiment, the pad plate 2 is provided with columns 16 that support the tray base plate 1 at intervals. These columns can be fixed with screws so that the tray base plate 1 and the pad plate 2 can rotate synchronously.

[0020] like Figure 1 As shown, semiconductor device positioning seats 4 are spaced apart on the tray substrate 1. Semiconductor devices 15 are placed on the semiconductor device positioning seats 4. The top surface of each semiconductor device positioning seat 4 has a recessed pin clearance groove 13 to allow clearance for the bottom pins of the semiconductor device 15. The numerous semiconductor device positioning seats 4 allow for individual positioning of the semiconductor devices 15, improving production efficiency. The tray substrate 1 is equipped with a handle 6 for easy handling by a robotic arm.

[0021] The cover plate 3 is suspended above the tray substrate 1, and a protective sleeve 14 is provided on the cover plate 3, which is concentrically fitted on the outside of the semiconductor device positioning seat 4. The protective sleeve 14 is used to limit the semiconductor device 15 around, thereby improving the positioning effect and stability during the transfer process.

[0022] The floating plate 5 is placed between the tray base plate 1 and the pad plate 2. The floating plate 5 is provided with a support rod 7 that extends upward through the tray base plate 1 and connects to the cover plate 3, so as to realize the synchronous lifting and lowering of the floating plate 5 and the cover plate 3.

A rotating cylinder 11 supporting the floating plate 5 is eccentrically provided on the rotating shaft 10. The floating plate 5 is driven to rise and fall by the rotation of the rotating cylinder 11. In this embodiment, a platform surface 12 is recessed on the outer wall of the rotating cylinder 11 away from the rotating shaft 10, such as... Figure 1 and Figure 3 As shown, at this time, the platform surface 12 is in contact with the bottom surface of the floating plate 5, and the floating plate 5 is in a high position.

[0024] like Figure 2 As shown, after the rotating shaft 10 rotates 180°, the platform surface 12 faces downward, the bottom surface of the floating plate 5 contacts the outer circle of the rotating cylinder 11 and descends, and the protective sleeve 14 descends accordingly to release the restriction on the semiconductor device 15 around its perimeter, making it convenient to load and unload the semiconductor device 15, and the operation is simple.

[0025] In this embodiment, one end of the rotating shaft 10 is provided with a radially extending handle 17, such as... Figure 3 As shown, the handle 17 allows for easy rotation switching of the shaft 10 by manual labor or a robotic arm, driving the floating plate 5 to rise and fall, and changing the position and height of the cover plate 3 and the protective sleeve 14.

[0026] To ensure the flexible descent of the sheath 14, an elastic element 8 is provided between the tray base plate 1 and the floating plate 5 to provide elastic drive for the floating plate 5 to return to its downward position. In this embodiment, the elastic element 8 is a spring and is sleeved on the support rod 7 for easy assembly.
