Description

Technical Field

[0001] This utility model relates to the field of LCoS chip manufacturing technology, specifically to a universal crystal filling fixture for multi-size LCoS chips. Background Technology

[0002] LCoS (Liquid Crystal on Silicon) is a type of chip based on reflective microdisplay technology. It integrates a liquid crystal layer directly onto a silicon-based semiconductor chip, displaying images by reflecting light.

[0003] In the production of LCoS chips, a crystal filling fixture is required to fill the liquid crystal layer. Existing crystal filling fixtures include a chip insertion frame assembly and a liquid crystal bar placement assembly. The chip insertion frame assembly includes several ribs arranged side by side, while the liquid crystal bar placement assembly includes a placement tray and several liquid crystal bars placed on the placement tray. During crystal filling, several chips are inserted one by one between several adjacent ribs, and at the same time, several liquid crystal bars are manually placed one by one directly below several chips, so that the crystal filling port of each chip matches the corresponding liquid crystal bar, and crystal filling is performed by capillary principle.

[0004] While the above method can perform crystal filling operations on the liquid crystal layer of the chip, the ribs in the chip mounting assembly are customized according to the chip specifications and are not universal. Different chips require replacement of the ribs, which increases the crystal filling cost. At the same time, the manual positioning of the liquid crystal ribs is troublesome, and the liquid crystal ribs are easily moved by external forces during the crystal filling process, which affects the normal crystal filling process.

Furthermore, the crystal filling principle of the LCoS chip is existing technology and will not be described in detail here.

[0032] like Figure 3-6As shown, according to another embodiment of the present invention, the universal die-filling fixture for multi-size LCoS chips is further optimized in terms of its mounting unit, die-filling unit, first locking member and second locking member.

Each mounting unit and each die-filling unit are slidably snapped between the two snap-fit ​​strips 33 of the corresponding mounting frame 3. The first locking member and the second locking member are both used to abut against the two snap-fit ​​strips 33.

[0033] Each of the aforementioned installation units includes a rib strip 6, both ends of which are slidably engaged with two locking strips 33 via first locking connectors 42.

The two connecting plates 31 are slidably connected to the two sliding rods 12 of the two lifting mechanisms.

[0043] The working principle of this utility model is as follows: When using this utility model, according to the specifications of the LCoS chip, loosen the first bolt 44 on each first card connector 42 so that it disengages from and abuts against the corresponding card strip 33. Then slide the rib strips 6 to adjust the distance between adjacent rib strips 6. After adjustment, tighten the first bolt 44 on each first card connector 42 so that it abuts against the corresponding card strip 33, thereby fixing the position of the rib strips 6. Then, insert several LCoS chips one by one into the slots 61 arranged facing each other between adjacent rib strips 6. Then loosen each second card... The second bolt 64 on connector 62 is used to disengage it from the corresponding snap-fit ​​strip 33. Then, the mounting plate 4 is slid to move the liquid crystal bar 5 so that the liquid crystal slot 51 is aligned with the LCoS chip. After adjustment, the second bolt 64 on each second snap-fit ​​connector 62 is tightened to abut against the corresponding snap-fit ​​strip 33, thereby fixing the position of the mounting plate 4. Then, the two telescopic cylinders 2 are activated to move the mounting frame 3 of the crystal filling module upward until the LCoS chip crystal filling port is inserted into the liquid crystal slot 51. Then, the two telescopic cylinders 2 are stopped, and the LCoS chip can then be crystal filled.
