Abstract
Description
Technical Field
[0001] This utility model relates to the field of BOSA production technology, and in particular to a BOSA laser welding device. Background Technology
[0002] In the production of BOSA (Board of Independent Laser Diodes), the BOSA housing (square base) needs to be assembled and welded to the TO (Laser Diode) fitting. In existing technology, the TO fitting and square base are structurally assembled, and then the assembled TO fitting and square base are manually welded together for use as a complete unit. This manual welding production method has low production efficiency, high production costs, and inconsistent operator skill levels, easily leading to poor product quality consistency. This is especially true at high production volumes, where such operations are inefficient and labor-intensive. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide a BOSA laser welding device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: a BOSA laser welding device, comprising a working platform, a linear motion slide table, a feeding assembly on the slider of the linear motion slide table, two spaced-apart mounting plates on the front side of the working platform located at the feeding assembly, a transverse slide cylinder fixed between the tops of the two mounting plates, a mounting seat fixed on the top of the slider of the transverse slide cylinder, one or more adapter seats spaced apart on the top of the mounting seat for placing the BOSA device to be welded, one or more support adjustment mechanisms respectively located on both sides of the transverse slide cylinder, a welding torch mounted on the top of the support adjustment mechanism, and a welding adjustment assembly for adjusting the horizontal and vertical positions of the welding torch.
[0005] Furthermore, the support adjustment mechanism includes a pad bracket, and a welding adjustment assembly is installed on the top of the pad bracket. A welding mounting base plate is installed on the top of the welding adjustment assembly or is connected to the welding mounting base plate through a welding bracket.
[0006] Furthermore, the welding adjustment assembly is a three-axis precision micro-adjustment slide.
[0007] Furthermore, the adapter has a receiving hole in the middle, and a limiting protrusion located on one side of the receiving hole is provided on the top of the adapter.
[0008] Furthermore, the feeding assembly includes a longitudinal displacement cylinder fixed on the slider of the linear motion slide. The output end of the longitudinal displacement cylinder is vertically downward and fixed with a support. The support is equipped with a shaft support seat, and the shaft support seat is rotatably connected to a rotating shaft. A motor seat is installed on the top of the support, and a motor is fixed on the top of the motor seat. The output end of the motor is connected to the top end of the rotating shaft. The bottom end of the rotating shaft is located at the bottom of the support and is fixed with a mounting plate. A finger cylinder is fixed to the bottom of the mounting plate.
[0009] Furthermore, a conductive slip ring is installed on the rotating shaft. Beneficial effects
[0010] Compared to existing technologies, this invention offers at least the following advantages: With the cooperation of a linear motion slide and a feeding assembly, a finger cylinder places the BOSA device to be welded onto the adapter, inserting its pins into the receiving holes with the welding position facing upwards. The transverse slide cylinder then moves the adapter, now containing the BOSA device, to the welding area formed by multiple welding torches. The welding torches then weld the BOSA device from multiple angles. Simultaneously, the linear motion slide, in conjunction with the feeding assembly, picks up another BOSA device to be welded and places it into the receiving hole of the next adapter, awaiting welding. After the BOSA device at the previous station's adapter is welded, the transverse slide cylinder moves the BOSA device from the next station's adapter to the welding area for welding by the welding torch, and this cycle repeats. This invention results in high product quality consistency, high efficiency, and reduced labor costs. Attached Figure Description
