Abstract
Description
Technical Field
[0001] This utility model relates to the field of automated assembly technology of laser devices, specifically to a laser module loading angle correction device, which is used to achieve high-precision angle detection and angle correction during the automated loading process of laser modules. Background Technology
[0002] In recent years, laser technology and its applications have developed rapidly, and have been widely used in scientific research, industrial manufacturing, national defense construction, biomedicine, information industry, resources and environment, and cultural entertainment.
[0003] However, there are many challenges in loading semi-finished modules during the manufacturing process of laser modules. On the one hand, the modules contain optical components and must be protected from contamination by dust, liquids, grease, etc., as well as collisions and vibrations between modules. On the other hand, traditional manual loading methods and existing automated vibratory feeders or conveyor belt transport methods have angular deviations when the modules enter the assembly station. It is difficult to control the angular deviation within ±2°, and excessive angular deviation will affect subsequent optical alignment, such as the coupling between the laser diode and the lens. Furthermore, due to inconsistent material postures during vibratory feeders or conveyor belt transport, the module chip pins are also prone to bending and damage to the appearance, making it difficult to guarantee product yield and assembly efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a laser module feeding angle correction device with a reasonable structure and reliable use, which solves the problem of poor assembly accuracy caused by the deviation of the incoming material posture of semi-finished modules. It adopts a visual recognition sensor to identify the angle of the module chip pins, which is conducive to automatic correction and significantly improves the assembly accuracy.
[0005] The technical solution of this utility model is:
[0006] A laser module loading angle correction device includes an adapter plate. The key technical features are: a servo motor is fixed to the top surface of the adapter plate; the output shaft of the servo motor passes through the adapter plate and is fixed to a flange connecting plate; a three-jaw cylinder is fixed to the center of the lower surface of the flange connecting plate; a vision bracket and a power supply bracket are fixed to both sides of the three-jaw cylinder on the flange connecting plate; a vision sensor is fixed to the outer side of the vision bracket, with the detection port of the vision sensor facing downwards; a longitudinal guide rod cylinder is fixed to the outer side of the power supply bracket; a horizontal support arm is connected to the lower end of the telescopic rod of the longitudinal guide rod cylinder; the other end of the horizontal support arm extends towards the center of the three jaws of the three-jaw cylinder and is fitted with a probe sleeve; three longitudinal power supply probes are mounted on the probe sleeve, with the probe heads of the longitudinal power supply probes facing downwards.
[0007] The aforementioned laser module loading angle correction device uses a concave-convex structure to connect and position the root of the gripper to the output end of the three-jaw cylinder. The gripper has an arc-shaped gripper arm, and the concave sides of the arc-shaped gripper arms of the three grippers are arranged opposite each other to ensure the strength of the force and leave enough space to facilitate the lifting and lowering of the probe sleeve. The lower end of the arc-shaped gripper arm is a straight clamping end, and the inner wall of the straight clamping end is provided with a triangular clamping groove, which is suitable for the clamping requirements of laser modules of different diameters, and has good clamping stability, thereby significantly enhancing the assembly accuracy.
[0008] In the aforementioned laser module loading angle correction device, the center line of the three-jaw cylinder coincides with the center line of the output shaft of the servo motor. The outer wall of the cylinder body of the three-jaw cylinder is provided with a limiting block for adjusting the stroke of the gripper. The limiting block is provided with a stroke adjustment set screw. The inner end of the stroke adjustment set screw faces the output end of the three-jaw cylinder or the gripper connected to the output end. By adjusting the stroke adjustment set screw, it is suitable for clamping and positioning laser modules with different outer diameters, and has high flexibility in use.
[0009] The laser module loading angle correction device described above has a clamping sensor and a releasing sensor installed on the lower surface of the three-jaw cylinder.
[0010] In the aforementioned laser module loading angle correction device, a lift sensor and a drop sensor are fixed on the outer wall of the longitudinal guide rod cylinder.
[0011] The laser module loading angle correction device described above has a horizontal support arm with an elongated mounting hole at one end corresponding to the telescopic end of the longitudinal guide rod cylinder, so as to adjust the probe sleeve and the three-jaw cylinder to be arranged concentrically. The other end of the horizontal support arm has a longitudinal through hole corresponding to the probe sleeve and a radial screw hole on the hole wall, and a positioning set screw is provided in the radial screw hole.
[0012] The beneficial effects of this utility model are:
[0013] 1. When picking up laser modules, the vision sensor identifies the direction of the power supply pins, and the servo motor rotates and corrects to the standard angle according to the detection signal, ensuring the consistency and accuracy of laser module calibration and processing. This solves the problem of poor assembly accuracy caused by the deviation of the incoming material posture of semi-finished modules. The use of a vision recognition sensor to identify the angle of the module chip pins is conducive to automatic correction and significantly improves assembly accuracy.

A vision bracket 4 and a power supply bracket 6 are fixed to both sides of the three-jaw cylinder 14. A vision sensor 5 is fixed to the outer side of the vision bracket 4, with the detection port of the vision sensor 5 facing downwards. A longitudinal guide rod cylinder 7 is fixed to the outer side of the power supply bracket 6. The lower end of the telescopic rod of the longitudinal guide rod cylinder 7 is connected to a horizontal support arm 10. The other end of the horizontal support arm 10 extends toward the center of the three jaws 17 of the three-jaw cylinder 14 and is fitted with a probe sleeve 11. Three longitudinal power supply probes 13 are mounted on the probe sleeve 11, with the probe heads of the longitudinal power supply probes 13 facing downwards. In this embodiment, a lift sensor 8 and a drop sensor 9 are fixed to the outer wall of the longitudinal guide rod cylinder 7. The lift sensor 8 and the drop sensor 9 are normally open magnetic switches. When the cylinder rod of the longitudinal guide cylinder 7 rises or falls, the internal piston moves. The piston is equipped with a magnetic ring. When it approaches the lift sensor 8 or the drop sensor 9, the normally open contact closes and feeds back an electrical signal to the control system, thereby realizing automatic control.
[0025] One end of the horizontal support arm 10 is provided with an installation elongated hole corresponding to the telescopic end of the longitudinal guide rod cylinder 7, so as to adjust the probe sleeve 11 and the three-jaw cylinder 14 to be arranged concentrically. The other end of the horizontal support arm 10 is provided with a longitudinal through hole corresponding to the probe sleeve 11 and a radial screw hole is provided on the hole wall. A positioning set screw 12 is provided in the radial screw hole.
[0026] The root of the gripper 17 is connected and positioned to the output end of the three-jaw cylinder 14 using a concave-convex structure. The gripper 17 has arc-shaped gripper arms, and the concave sides of the arc-shaped gripper arms of the three grippers 17 are arranged opposite each other to ensure force strength while leaving sufficient space, facilitating the lifting and lowering of the probe sleeve 11. The lower end of the arc-shaped gripper arm is a straight clamping end, and the inner wall of the straight clamping end is provided with a triangular clamping groove, which is suitable for clamping requirements of laser modules 20 of different diameters, with good clamping stability, thereby significantly enhancing assembly accuracy. The centerline of the three-jaw cylinder 14 coincides with the centerline of the output shaft of the servo motor 1. A limiting block 15 for adjusting the stroke of the grippers is provided on the outer wall of the cylinder body of the three-jaw cylinder 14. A stroke adjustment screw 16 is provided on the limiting block 15, with the inner end of the screw facing the output end of the three-jaw cylinder 14 or the gripper 17 connected to the output end. By adjusting the stroke adjustment screw 16, it is suitable for clamping and positioning laser modules 20 with different outer diameters, offering high flexibility. A clamping sensor 18 and a release sensor 19 are installed on the lower surface of the cylinder body of the three-jaw cylinder 14. The clamping sensor 18 and the release sensor 19 are normally open magnetic switches. When the piston inside the three-jaw cylinder 14 moves, a magnetic ring on the piston approaches the clamping sensor 18 or the release sensor 19, closing the normally open contact and feeding back an electrical signal to the control system, thereby achieving automated control.
[0027] Working principle:
