AI Technical Summary
Traditional manual mounting cannot meet the positional consistency requirements of large optical device housings. Vacuum adsorption can easily lead to movement, and the flexible tape is easily damaged during the mounting process, affecting the packaging test and usage results.
The lower and upper base plate clamps are fixed by a magnetic attraction device. Precise positioning is achieved through a magnetic device and positioning pins, avoiding vacuum adsorption and twisting operations. A soft strap placement groove is provided to protect the soft strap from damage.
It improves the accuracy and consistency of optical device mounting positions, avoids damage to the housing and flexible tape, and ensures the reliability of packaging testing and use.

Abstract
Claims
1. An internal mounting fixture for a BOX-packaged device, characterized in that: The device includes a lower base plate clamp with a magnetic attraction device and an upper base plate clamp for fixing the BOX sealing surface. The lower base plate clamp has a connected housing fixing groove and a flexible tape placement groove in the middle, which are respectively matched with the outer dimensions of the housing and flexible tape of the BOX packaging device. An embedded magnet device is provided near the housing fixing groove and the flexible tape placement groove. A positioning hole is provided near the magnet device. A mounting window is provided in the middle of the upper base plate clamp. The position of the mounting window corresponds one-to-one with the position of the housing fixing groove. A positioning pin is connected to the upper base plate clamp. The thickness and position of the positioning pin match the positioning hole.
2. The internal mounting jig of a BOX package device according to claim 1, wherein: The magnet is fixed in a circular hole on the bottom plate clamp. The circular hole is located on the upper side of the tube shell fixing groove and the lower side of the soft strip placement groove. The size of the magnet is matched with that of the circular hole.
3. The internal die attach tool for a BOX package device of claim 1, wherein: The positioning holes are located at opposite corners on both sides of the lower base plate fixture.
4. The internal die attach jig of claim 1, wherein: The depth of the casing fixing groove is 0.2 mm less than the height of the BOX packaged device casing.
5. The internal die attach tool for a BOX package device of claim 1, wherein: The mounting window size is 0.1 mm smaller than the outer dimensions of the BOX packaged device casing and not larger than the inner dimensions of the BOX packaged device casing.
6. The internal die attach tool for a BOX package device of claim 1, wherein: The positioning pins are located at diagonal positions on the left and right sides of the upper base plate clamp.
7. An internal mounting jig for a BOX package device according to any one of claims 1 to 6, characterized in that: The upper base plate clamp and the lower base plate clamp are tightly attached by a magnetic attraction device.
