Description

Technical Field

[0001] This utility model belongs to the field of lens coupling technology, and specifically relates to a lens coupling worktable. Background Technology

[0002] Lens coupling refers to the process of using a lens to transmit light from one optical element to another; in this process, the lens plays the role of focusing, collimating, or changing the direction of light.

[0003] The device coupling process is as follows: The heat sink is fixed on the heat sink fixture. A power-on probe is placed against the transition heat sink of the chip to apply power. The lens is clamped using lens grippers. The size of the light spot is observed using a beam analyzer. The lens position is adjusted until the light spot is minimized, then the lens is slowly moved towards the chip. As the light spot increases, the beam analyzer is moved back and forth to measure the beam divergence angle, keeping the divergence angles X and Y within the range of 0–0.1. After the lens position is adjusted, the beam analyzer is adjusted so that the light spot aligns with the center point of the beam analyzer, and the Z-axis of the beam analyzer remains stationary. The lens is then lifted upwards, and a probe is placed at the position corresponding to the heat sink. Apply UV adhesive, then move the lens back to its original position, confirming that the bottom of the lens is in contact with the adhesive, and observe the light spot in the beam analyzer. Fine-tune the lens position, and after confirming the optimal position, irradiate the adhesive-covered area with a UV curing lamp. After irradiation, release the lens clamps and remove the lens, recording the optical power and divergence angle measured by the beam analyzer at this time. After all lenses are coupled, place the heat sink in a high-temperature oven for baking for 24–48 hours. After removing it, use the beam analyzer to measure the chip power and divergence angle respectively, comparing the values ​​measured before high-temperature baking to see if the lens position has shifted or if the chip power has decreased. If the chip power is not a problem, install the heat sink into the casing and wire bond it.

[0004] In practical applications, the disassembly and regular maintenance of the beam analyzer are essential steps. Since the beam analyzer needs to be precisely aligned during assembly to ensure the accuracy of its measurement results, even a slight positional shift during disassembly and reassembly can lead to deviations in the measurement results, thereby affecting the accuracy and efficiency of lens coupling.

[0005] The existing lens coupling stage is inadequate in dealing with the problem of beam analyzer assembly position misalignment; it lacks an effective positioning mechanism to ensure that the beam analyzer can be quickly restored to its original position after disassembly and reassembly.
