Description

Technical Field

[0001] This invention belongs to the technical field of automatic dispensing devices, and specifically relates to a dispensing device with a precision adjustable angle. Background Technology

[0002] In the manufacturing process of communication devices, the dispensing of ferrules and the insertion of optical fibers are critical steps. Existing dispensing equipment suffers from the following technical deficiencies: (1) Poor fiber threading stability: For non-standard ferrules without horn openings at both ends, it is difficult to accurately position and stably thread the optical fiber into the ferrule hole, resulting in low fiber threading success rate and high product scrap rate; (2) Insufficient adaptability: The dispensing angle is mostly fixed and cannot be flexibly adjusted according to different shapes and sizes of ferrule components. It can only be adapted to a single specification of workpiece, and the scope of application is narrow; (3) Low precision and efficiency: There is a lack of accurate visual positioning system, the dispensing position deviation is large, and it relies heavily on manual assistance for feeding and adjustment, resulting in low production efficiency and difficulty in meeting the needs of mass production; (4) Low cost performance: Some high-precision dispensing devices have complex structures, high costs, and high maintenance costs, which are not conducive to the promotion and application of small and medium-sized enterprises. Given the shortcomings of the existing technologies, there is an urgent need for a dispensing device that can balance accuracy, adaptability, efficiency, and cost to solve the problem of non-standard ferrule processing and promote the upgrading of industry production.

The base is fixed to the base plate, and two mounting plates are vertically fixed on the front and rear sides above the base. A top plate is fixed to the top of the two mounting plates. The angle adjustment seat is rotatably connected between the two mounting plates via the angle adjustment shaft. The servo motor is mounted on... The upper part of the angle adjustment seat has the left end of the workpiece rotation axis passing through it laterally and connected to the output shaft of the servo motor via a transmission device. The workpiece rotation axis and the angle adjustment seat are rotatably connected. The left end of the position adjustment seat is mounted on the top plate via a first XY axis precision adjustment table. The first XY axis precision adjustment table can move the position of the position adjustment seat in the X and Y axis directions. The dispensing syringe is vertically mounted above the workpiece rotation axis. The dispensing syringe is mounted on the right end of the position adjustment seat via a first Z axis precision adjustment table. The first Z axis precision adjustment table can move the position of the dispensing syringe in the Z axis direction.

[0004] The visual recognition mechanism is located on the right side behind the dispensing mechanism and corresponds to the position of the workpiece rotation axis. It is used to automatically identify the position and status of the workpiece on the workpiece rotation axis.

[0009] Preferably, the two mounting plates are respectively provided with front and rear opposite arc-shaped guide grooves, and the angle adjustment shaft is located at the center of the arc-shaped guide groove. Two guide pins are fixed at the front and rear ends of the angle adjustment seat, and the two guide pins are respectively inserted into the arc-shaped guide grooves on the corresponding sides to limit the angle adjustment of the angle adjustment seat.

[0014] The working principle of this invention is as follows: A non-standard ferrule workpiece is placed on the workpiece rotation axis. The positions of the adjustment frame and the high-definition CCD vision recognition camera are adjusted using the second XY-axis precision adjustment stage and the second Z-axis precision adjustment stage until the hole position and edge of the ferrule are clearly displayed on the monitor. The angle adjustment axis is rotated to adjust the angle adjustment seat. The dispensing angle is set according to the ferrule specifications. The position of the dispensing syringe is adjusted using the first XY-axis precision adjustment stage and the first Z-axis precision adjustment stage. The dispensing position is set, along with parameters such as dispensing time and dispensing pressure. Then, the servo motor is started to drive the workpiece to rotate and dispensing begins. After dispensing is completed, the system guides the optical fiber through the ferrule hole using the high-definition CCD vision recognition camera. During the fiber threading process, the position deviation is monitored and corrected in real time. Finally, the processed workpiece is removed, and the next round of operation begins.

[0015] The beneficial effects of this invention are: (1) High precision: The angle adjustment accuracy reaches ±0.1°. Combined with high-definition CCD visual recognition positioning and precise X, Y, Z axis adjustment, the glue dispensing position deviation is extremely small, which can stably solve the problem of non-standard ferrules without flared openings and greatly improve the fiber insertion success rate.

[0016] (2) Strong adaptability: By combining the angle adjustment shaft and the angle adjustment seat, it can be adapted to various ferrules of different diameters and lengths without the need to replace special clamps, and has a wide range of applications.

[0017] (3) High efficiency: The workpiece rotating shaft realizes automatic feeding and rotation, and the electrical control box is fully automatic, which greatly shortens the workpiece processing time and significantly improves production efficiency.

[0018] (4) Easy to operate: Each adjustment component (XY axis precision adjustment stage, Z axis precision adjustment stage, angle adjustment axis) is equipped with scale and locking knob, and operators can quickly complete parameter settings without professional training.

[0019] (5) High cost performance: The device has a simple structure, the core components adopt standardized design, the cost is low, and the maintenance cost is low, making it suitable for mass production applications of small and medium-sized enterprises. Attached Figure Description
