Abstract
Description
Technical Field
[0001] The utility model relates to mechanical equipment, in particular to a coupling adjustment device. Background Art
[0002] The stability and performance of the TX and RX ends in optical communication devices can have a significant impact on the data transmission quality of the entire optical communication. Therefore, TX coupling and RX coupling during optical communication are very important processes. The traditional production process has high requirements for operators. Coupling is mainly performed manually, which is inefficient and has a low yield rate. The automatic coupling machines available on the market can reduce labor intensity and improve the yield rate to a certain extent, but there is still low work efficiency. Frequent loading and unloading of workpieces not only increases labor costs, but also reduces the service life of workpieces to a certain extent, and cannot achieve continuous coupling welding. At present, in the optical device coupling welding process, usually after the coupling is completed, the adjustment ring and the laser (LD) are first welded by penetration welding, and then the adjustment ring and the base (BASE) are welded by lap welding. During coupling, the coaxiality requirements of the laser and the base are high, and deviations are prone to occur during the coupling process. During welding, there is a certain welding gap between the base (BASE) and the adjustment ring, and it is difficult to achieve uniform welds, so the yield rate is low. Utility Model Content

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] As shown in the accompanying drawings, this embodiment provides a coupling angle adjustment device, including a base 1, a deflection platform 2, a locking mechanism sleeved on the outer periphery of the deflection platform 2 for loosening or fixing the deflection platform 2, and a rotating mechanism 4 for driving the base 1 to rotate, the locking mechanism is connected to the base 1, an elastic supporting mechanism 5 is arranged between the deflection platform 2 and the base 1, a limited ball head 6 is arranged on the locking mechanism, a limited groove 21 matched with the limited ball head 6 is arranged on the deflection platform 2, and a clamping mechanism for clamping an optical device is arranged on the deflection platform 2, and the clamping mechanism follows the deflection of the deflection platform 2;
[0023] The deflection platform 2 is a circular structure, and the limiting groove 21 is a semicircular groove, which cooperates with the limiting ball head 6 to complete the rotation limit of the deflection platform 2, so that it can only move up and down or make a small deflection, thereby achieving the effect of synchronous rotation with the base 1. The deflection platform 2 is provided with a power-on mechanism, which includes a lifting cylinder 81 and a power-on seat 82 connected to the lifting cylinder 81;
[0024] The locking mechanism includes an elastic frame 31 and a locking cylinder 32 for loosening or fixing the deflection platform 2. The head and tail ends of the elastic frame 31 are respectively provided with a bending portion 311 protruding outward, and the locking cylinder 32 is connected to the bending portion 311. A limit block 312 is provided on the elastic frame 31. There is a gap between the limit block 312 and the deflection platform 2. The limit block 312 limits the deflection angle of the deflection platform 2, so that it can be slightly deflected.
[0025] The rotating mechanism 4 includes a rotating motor 41, a driving wheel 42, a driven wheel 43 and a belt 44. The rotating motor 41 is rotatably connected to the driving wheel 42. The belt 44 is sleeved on the driving wheel 42 and the driven wheel 43. The driven wheel 43 is fixedly connected to the base 1 to drive the base 1 to rotate.
[0026] The elastic support mechanism 5 includes a spring 51 and an elastic telescopic rod 52. The elastic telescopic rod 52 is fixedly arranged on the base 1. One end of the spring 51 is connected to the deflection platform 2, and the other end is sleeved on the elastic telescopic rod 52, so as to support and cooperate with the fine adjustment of the angle of the optical device.
[0027] The clamping mechanism includes a clamp 71 and a clamping cylinder 72 arranged under the deflection platform 2 for driving the clamp 71 to open or close. The clamping cylinder 72 drives the clamp 71 to clamp the optical device. The clamp 71 includes a fixed clamp 711 and a movable clamp 712. The deflection platform 2 is provided with a fixed groove 22 for installing the fixed clamp 711, and a track groove 23 for the movable clamp 712 to move. The movable clamp 712 passes through the track groove 23 and is connected to the clamping cylinder 72.
[0028] When the coupling work is in progress, the clamping cylinder 72 located under the deflection platform 2 is driven, and the movable clamp 712 connected to the clamping cylinder 72 moves along the track groove 23 to cooperate with the fixed clamp 711 to clamp the optical device. Then the lifting cylinder 81 located on the deflection platform is started, driving the power-on seat 82 to move to the power-on hole of the coupling welding fixture, cooperating with the base of the optical device, and powering the base of the optical device. Then the locking cylinder 32 of the locking mechanism is started, driving the elastic frame 31 to expand outward to reduce the fixation of the deflection platform 2 so that it can be fine-tuned. At this time, the force applied by the elastic support structure 5 to the deflection platform 2 makes it close to the limit block 312, so as to achieve the state that the deflection platform 2 is basically kept horizontal. Then the rotating motor 41 is started to drive the driving wheel 42 to rotate. 2 drives the driven wheel 43 to rotate through the belt 44, thereby driving the base 1 to rotate. The base 1 is designed as an integrated unit with the locking mechanism. At this time, the limit ball head 6 cooperates with the limit groove 21 to limit the rotation of the deflection platform 2, so that it can only move up and down or make a slight deflection, so as to achieve the effect of synchronous rotation with the base. At this time, the machine fixture drives the laser of the optical device to press down to find light. During this period, the deflection platform 2 makes a slight deflection and moves up and down according to the movement of the laser, thereby driving the substrate to follow the deflection. When the control system determines that the coupling value reaches the maximum, the rotating motor 41 stops moving, and the locking cylinder 32 drives the elastic frame 31 to fix the deflection platform 2. When the coupling is completed, the clamping cylinder 72 drives the movable clamp 712 to release the optical device and couple the next optical device.
