Description

TECHNICAL FIELD

[0001] The application relates to the technical field of chip packaging, and particularly relates to a Tray disc base capable of being automatically inducted and fixed. BACKGROUND

[0002] In a semiconductor packaging process, a chip mounting and flip process is arranged, and the purpose of the chip mounting and flip process is to mount chips to fixed areas of a lead frame and a substrate according to position requirements of a drawing. A conventional product customer provides a wafer, and the wafer is mounted and flipped by being ground, scribed and pasted on a blue film or a UV film. Currently, some customers provide a Tray disc, and chips are stored in the Tray disc. The chip mounting and flip are directly performed on the Tray disc. In the prior art, as shown in the figure, a Tray disc storage base is a fixed support plus a card control, but the Tray disc has a falling risk, and the Tray disc cannot be mounted in place, which leads to tilting and causes a chip bruising and cracking risk. Figure 1

[0003] Therefore, a Tray disc base capable of being automatically inducted and fixed is required, which can adapt to wafers of various sizes and can ensure that the wafers are mounted in place. SUMMARY

[0004] The application aims to solve the problems of the prior art that the Tray disc cannot be mounted in place, tilting leads to a chip bruising and cracking risk, and provides a Tray disc base capable of being automatically inducted and fixed.

[0005] The Tray disc base capable of being automatically inducted and fixed comprises a Tray disc base, and the Tray disc base is characterized in that an upper surface of the Tray disc base is inwardly recessed to form a plurality of first recesses and second recesses, each of the first recesses and the second recesses forms a loading area, a group of slotted tracks are uniformly distributed in the middle of the loading area, and a movable pressure sensor is arranged in the slotted track.The first recesses and the second recesses can provide specific space for placing the Tray disc, and ensure the stability of the Tray disc on the Tray disc base. The group of slotted tracks uniformly distributed in the middle of the loading area can be used to guide the Tray disc to be correctly placed, and provide installation space for the movable pressure sensor and other devices. The movable pressure sensor can be used to detect whether the Tray disc has been correctly placed in the loading area. When the Tray disc is placed in the slotted track, the pressure sensor can sense the change of pressure, so as to confirm the in-place condition of the Tray disc.

[0006] Furthermore, the tray base also includes a fixing device. A U-shaped fixing rod is rotatably mounted on the top of the fixing device. One end of the U-shaped fixing rod is fixedly connected to the fixing device, and a circular rubber head is sleeved on the other end of the U-shaped fixing rod. The circular rubber head moves on the surface of the installed tray and can fix the tray on the surface of the tray to prevent the tray from falling off or moving.

[0007] Furthermore, a stop bar groove is provided at the notch position of the loading area, and a thrust stop bar is provided in the stop bar groove. The thrust stop bar moves in the stop bar groove. After the tray is fixed, the thrust stop bar is pushed to the notch position for fixing and positioning. The thrust stop bar moves in the stop bar groove and can be adjusted synchronously with the size of the tray and the pressure sensor.

[0008] Furthermore, there are at least four slotted tracks arranged diagonally; the diagonally arranged pressure sensors can provide more comprehensive coverage, ensuring the stability and balance of the tray on the tray base. This layout helps to detect the force on the tray at different positions, thereby achieving more accurate sensing and fixation; the movable pressure sensors can be adjusted in position as needed to adapt to trays of different sizes and shapes; this flexibility allows the base to be used with a variety of tray specifications, increasing the base's versatility.

[0009] Furthermore, the length of the slotted track ranges from 1.5 ± 0.5 mm.

[0010] Furthermore, the length of the stop bar groove ranges from 2 ± 0.5 mm.

[0011] Furthermore, the first groove is placed vertically in the loading area, and the second groove is placed horizontally in the loading area, which facilitates the loading and unloading of the tray.

[0012] Beneficial effects: Compared with the prior art, the advantages of the present invention are as follows:

[0013] (1) The present invention has a slotted track and a movable pressure sensor in the loading area, which can ensure the stability and balance of the tray on the tray base; and the movable pressure sensor can be adjusted as needed to adapt to trays of different sizes and shapes; this flexibility makes the base suitable for a variety of tray specifications, increasing the versatility of the base.

[0014] (2) The present invention is designed with a fixing device and a U-shaped fixing rod, which can fix the tray on the surface of the tray to prevent the tray from falling off and moving.

[0015] (3) The present invention is designed with a stop bar groove and a thrust stop bar. After the tray is fixed, the thrust stop bar can be pushed to the notch position for fixing and positioning. The thrust stop bar moves in the stop bar groove and adjusts the position of the movable sensor synchronously according to the size of the tray. Attached Figure Description

[0020] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the embodiments described.

[0021] like Figure 2 The diagram illustrates a tray base for automatic sensing and fixing of a tray. The upper surface of the tray base is recessed inward to form four first grooves 1 and two second grooves 2. The four first grooves 1 are vertically arranged around the entire tray base, while the two second grooves 2 are horizontally arranged in the center of the tray base. Each first groove 1 and second groove 2 forms a loading area. Four slotted tracks 3 are evenly distributed in the center of the loading area, arranged diagonally. A movable pressure sensor 4 is installed inside each slotted track 3. The movable pressure sensor can move within the slotted track, and its position can be adjusted according to the tray size to ensure timely pressure monitoring at the bottom of the tray. In this embodiment, the length of the slotted track 3 is 1.5 mm.

[0022] like Figure 3 As shown, the tray base also includes a fixing device 5. A U-shaped fixing rod 6 is rotatably mounted on the top of the fixing device 5. One end of the U-shaped fixing rod 6 is fixedly connected to the fixing device 5, and a round rubber head 7 is sleeved on the other end of the U-shaped fixing rod 6.

[0023] like Figure 4 As shown, a stop bar groove 8 is provided at the notch position of the loading area, and a thrust stop bar 9 is provided in the stop bar groove 8. The thrust stop bar 9 moves within the stop bar groove 8. In this embodiment, the length of the stop bar groove 8 is 2mm.

[0024] During use, the operator places the Tray on the Tray base. After the four pressure sensors confirm that it is compacted, the operator moves to the four-sided fixing device and presses it against the edge of the Tray to confirm that it is secure. The operator then pushes the thrust lever to the notch position of the Tray to fit it in place. After confirming that the direction is correct, the operator repeats the above steps until all Trays are installed and the machine is put into production.

[0025] As described above, although the invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the invention itself. Various changes in form and detail may be made without departing from the spirit and scope of the invention as defined in the appended claims.
