Description

Technical Field

[0001] This invention relates to the field of optical modem performance testing, specifically to an automatic feeding and conveying device for optical modem performance testing. Background Technology

[0002] An optical modem, also known as a single-port optical transceiver, is a three-piece fiber optic transmission device developed for specific user environments. This device uses large-scale integrated chips, featuring simple circuitry, low power consumption, high reliability, complete alarm status indication, and comprehensive network management functions. Before leaving the factory, the optical modem undergoes performance testing. Those that pass the test are packaged and shipped; those that fail are returned for repair. During performance testing, the optical modem is transported to the testing machine via a conveyor mechanism. After being output from the previous workstation, the optical modem is transported on the conveyor with varying postures, and its position changes during transport. However, current conveyor systems cannot adjust the posture of the optical modem, causing it to not accurately align with the testing station after being loaded onto the testing machine, thus affecting the testing process.

[0005] Furthermore, the attitude adjustment conveyor belt includes a conveyor frame, an input roller, an output roller, an inclined roller, a horizontal roller, and a conveyor belt. The input roller, the inclined roller, and the horizontal roller are rotatably arranged sequentially on the conveyor frame along the conveying direction of the optical modem. There are at least two inclined rollers. Horizontal rollers are rotatably arranged between the input roller and the inclined roller, and between the output roller and the inclined roller. The conveyor belt is fitted onto the input roller, the output roller, the inclined roller, and the horizontal roller. A horizontal conveying surface is formed between the input roller and the nearest horizontal roller, and between the output roller and the nearest horizontal roller. An attitude adjustment plane is formed between the inclined rollers.

[0006] Furthermore, each of the inclined rollers corresponds to two pressing shafts, which are respectively arranged at both ends of the inclined roller. The pressing shafts are rotatably connected to the conveyor frame and are located above the inclined rollers to compress the conveyor belt.

[0007] Furthermore, multiple vibrators are installed on the conveyor frame in the area of ​​the attitude adjustment plane.

[0008] Furthermore, the output end of the attitude adjustment conveyor belt is provided with a position adjustment mechanism, which includes a base and a rotating platform. The rotating platform is rotatably mounted on the base, and the top surface of the rotating platform is flush with the horizontal conveying surface of the output end of the attitude adjustment conveyor belt.

[0009] Furthermore, a positioning mechanism is provided on the rotating platform. The positioning mechanism includes a positioning end plate and a positioning side plate. The positioning end plate is fixed to the top of the rotating platform. The positioning side plates are fixed on both sides of the top surface of the rotating platform. The positioning side plates are perpendicular to the positioning end plate. A positioning push plate is provided between the two positioning side plates. The positioning push plate moves along the conveying direction perpendicular to the attitude adjustment conveyor belt.

[0010] Furthermore, a positioning cylinder is installed on one of the positioning side plates, and the telescopic shaft of the positioning cylinder passes through the positioning side plate and connects to the positioning push plate.

[0011] Furthermore, the rotary table has a conveying groove extending through its height. A first shaft and a second shaft are spaced apart in the conveying groove along the conveying direction of the attitude adjustment conveyor belt. Both the first shaft and the second shaft are rotatably connected to the rotary table. The first shaft is connected to the second shaft via a belt drive. A motor is installed on the side wall of the rotary table, and the output shaft of the motor is connected to the first shaft.

[0014] The beneficial effects of this invention are:

[0015] The optical modem is guided by the attitude adjustment plane of the attitude adjustment conveyor belt. With the vibration generated by the vibrator, the optical modem is conveyed forward and slides towards the bottom of the attitude adjustment plane. This allows the side wall of the optical modem to contact the conveyor frame and complete the alignment of the optical modem. When the optical modem is conveyed to the horizontal conveyor surface at the output end of the attitude adjustment conveyor belt, the color mark on the optical modem shell is within the detection range of the color sensor. The color sensor can only recognize color marks at the same height as itself. Therefore, the position of the optical modem can be determined by the response of the corresponding color sensor. Based on the position of the optical modem, the rotary table is rotated by the corresponding angle to achieve precise feeding of the optical modem. Attached Figure Description

Detailed Implementation

[0024] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0025] Example 1

[0026] like Figures 1 to 7As shown, an automatic feeding and conveying device for optical modem performance testing includes an attitude-adjusting conveyor belt 1. The attitude-adjusting conveyor belt 1 has an inclined attitude-adjusting plane 2, which is inclined along the conveying direction perpendicular to the attitude-adjusting conveyor belt 1. Both the input and output ends of the attitude-adjusting conveyor belt 1 are provided with horizontal conveying surfaces 3. Position detection components are provided on the horizontal conveying surface 3 at the output end of the attitude-adjusting conveyor belt 1. Four sets of position detection components are provided, spaced apart along the conveying direction of the attitude-adjusting conveyor belt 1. Each detection component includes a color sensor 4. The color sensors 4 in the four sets of position detection components are arranged at different heights. Color markings are painted on the four side walls of the optical modem housing, and the arrangement height of the color markings on the four side walls corresponds one-to-one with the arrangement height of the four color sensors 4. The detection is achieved by sensing a specific color sensor. The response of device 4 reflects the conveying posture of the optical modem. Multiple vibrators are installed on the conveyor frame 5 in the area of ​​the posture adjustment plane 2. The optical modems processed in the previous station are sent to the test station via the posture adjustment conveyor belt 1. The posture adjustment plane 2 of the posture adjustment conveyor belt 1 guides the optical modem. With the vibration generated by the vibrators, the optical modem is conveyed forward and slides towards the bottom of the posture adjustment plane 2, so that the side wall of the optical modem contacts the conveyor frame of the posture adjustment conveyor belt 1 to complete the alignment of the optical modem. When the optical modem is conveyed to the horizontal conveying surface 3 at the output end of the posture adjustment conveyor belt 1, the color mark on the optical modem shell is within the detection range of the color sensor 4. The color sensor 4 can only identify the color mark at the same height as itself. Therefore, the position of the optical modem can be determined by the response of the corresponding color sensor 4. The feeding position can be adjusted according to the position of the optical modem to achieve precise feeding of the optical modem.

[0027] Example 2

[0028] Based on Example 1, such as Figures 1 to 7 As shown, the output end of the attitude adjustment conveyor belt 1 is equipped with a position adjustment mechanism, which includes a base 12 and a rotating platform 13. The rotating platform 13 is rotatably mounted on the base 12, and the top surface of the rotating platform 13 is flush with the horizontal conveying surface 3 at the output end of the attitude adjustment conveyor belt 1. The optical cat, after position detection, is conveyed from the attitude adjustment conveyor belt 1 to the rotating platform 13. The position information of the optical cat detected by the color sensor 4 causes the rotating platform 13 to rotate by a certain angle, so that the position of the optical cat is directly in the feeding state. The optical cat can be accurately fed to the testing station directly by a feeding robot arm or other feeding mechanism.

[0029] Furthermore, a rotating spindle 22 is fixed to the bottom of the rotating table 13, and a mounting hole 23 is provided on the top of the base 12. The rotating spindle 22 is rotatably mounted in the mounting hole 23 through bearings. A drive motor 24 is mounted on the base 12. The output shaft of the drive motor 24 is connected to a drive gear 25. A driven gear 26 is fitted on the rotating spindle 22. The drive gear 25 meshes with the driven gear 26. The drive motor 24 drives the rotating spindle 22 to rotate through the meshing of the drive gear 25 and the driven gear 26. The rotating spindle 22 drives the rotating table 13 to rotate, so as to adjust the position of the optical modem according to the position information of the optical modem, so that it is in the feeding state.

[0030] Example 3

[0031] Based on Example 2, such as Figures 1 to 7 As shown, a positioning mechanism is provided on the rotary table 13. The positioning mechanism includes a positioning end plate 14 and a positioning side plate 15. The positioning end plate 14 is fixed to the top of the rotary table 13. Positioning side plates 15 are fixed on both sides of the top surface of the rotary table 13. The positioning side plates 15 are perpendicular to the positioning end plate 14. A positioning push plate 16 is provided between the two positioning side plates 15. The positioning push plate 16 moves along the conveying direction perpendicular to the attitude adjustment conveyor belt 1. A positioning cylinder 17 is installed on one of the positioning side plates 15. The telescopic shaft of the positioning cylinder 17 passes through the positioning side plate 15 and connects to the positioning push plate 16. A conveying groove 18 is provided through the rotary table 13 along its height direction. A first shaft 19 and a second shaft 20 are arranged at intervals in the conveying groove 18 along the conveying direction of the attitude adjustment conveyor belt 1. Both the first shaft 19 and the second shaft 20 are rotatably connected to the rotary table 13. The first shaft 19 is connected to the second shaft 20 through a belt drive. A motor 21 is installed on the side wall of the rotary table 13. The output of the motor 21... The optical modem is connected to the first shaft 19 via shaft drive. Although the position of the optical modem is adjusted on the attitude adjustment plane 2, it may still deviate during the process of being transported from the attitude adjustment conveyor belt 1 to the rotary table 13. Therefore, after the optical modem is transported to the rotary table 13, it needs to be adjusted again. Before adjusting the position, the optical modem is rotated by a certain angle according to the position information of the optical modem detected by the color sensor 4, so that the loading position of the optical modem is correct. The first shaft 19 is driven to rotate by the motor 21, and the first shaft 19 drives the second shaft 20 to rotate via the belt. The optical modem is moved closer to the positioning end plate 14 by the belt drive, so that the side wall of the optical modem contacts the positioning end plate 14. Then, the positioning cylinder 17 drives the positioning push plate 16 to move, so that the positioning push plate 16 pushes the optical modem closer to one of the positioning side plates 15, so that the other side wall of the optical modem contacts the positioning side plate 15, thereby completing the positioning of the optical modem and putting it in the test and loading state.

[0032] Example 4

[0033] Based on Example 3, such as Figures 1 to 7As shown, a positioning groove 27 is provided on the side wall of the mounting hole 23, and an electromagnet 28 is installed in the positioning groove 27. A positioning cone 29 is slidably arranged in the positioning groove 27. Four positioning holes 30 are evenly distributed along the circumference of the side wall of the rotating spindle 22. A permanent magnet 31 is connected to the end of the positioning cone 29 near the electromagnet 28. When the electromagnet 28 is energized, it generates a magnetic pole with a magnetic field opposite to that of the permanent magnet 31. A spring 32 is provided in the positioning groove 27. The end of the positioning cone 29 away from the permanent magnet 31 is fitted into one of the positioning holes 30. Since the optical modem is rectangular, after the optical modem is aligned on the rotating table 13, it can be adjusted to the loading position by rotating it 90°, 180° or 270°. To ensure that the rotating spindle 22 can rotate accurately 90°, 180° or 270°, the positioning cone 29 is provided. When the rotating table 13 needs to be rotated, the electromagnet 28 is energized. The permanent magnet 31 is attracted, causing the positioning cone 29 to squeeze the spring 32 and move into the positioning groove 27, thus disengaging the positioning cone 29 from the positioning hole 30. This allows the rotating spindle 22 to smoothly drive the rotating table 13 to rotate. The energizing time of the electromagnet 28 is controlled according to the rotation angle of the rotating spindle 22. When the rotating spindle 22 approaches but has not yet reached the required rotation angle, the electromagnet 28 is de-energized, causing the positioning cone 29 to move closer to the rotating spindle 22 under the reaction force of the spring 32. The positioning cone 29 then contacts the rotating spindle 22, and the drive motor 24 drives the rotating spindle 22 to rotate the specified angle and then stops. At this time, the positioning cone 29 is inserted into the positioning hole 30 of the rotating spindle 22 under the action of the spring 32, thereby locking the rotating spindle 22 and preventing the inertia of the drive motor 24 after it stops from causing the rotating spindle 22 to continue to deflect. This results in higher rotation accuracy of the rotating table 13 and precise adjustment of the optical modem position.

[0034] Example 5

[0035] Based on Example 4, such as Figure 1 and Figure 2As shown, the attitude-adjusting conveyor belt 1 includes a conveyor frame 5, an input roller 6, an output roller 7, an inclined roller 8, a horizontal roller 9, and a conveyor belt 10. The input roller 6, inclined roller 8, and horizontal roller 9 are sequentially rotatably arranged on the conveyor frame 5 along the conveying direction of the optical modem. At least two inclined rollers 8 are provided. Horizontal rollers 9 are rotatably arranged between the input roller 6 and the inclined roller 8, and between the output roller 7 and the inclined roller 8. The conveyor belt 10 is fitted onto the input roller 6, output roller 7, inclined roller 8, and horizontal roller 9. A horizontal conveying surface 3 is formed between the input roller 6 and the nearest horizontal roller 9, and between the output roller 7 and the nearest horizontal roller 9. An attitude adjustment plane 2 is formed between the inclined rollers 8. A stepper motor is installed on the conveyor frame 5. The output shaft of the stepper motor is connected to one end of the input roller 6. The input roller 6 is driven to rotate by the stepper motor. The input roller 6 drives the output roller 7, inclined roller 8 and horizontal roller 9 to rotate through the conveyor belt 10. By setting multiple inclined rollers 8, the conveyor belt 10 forms an inclined attitude adjustment plane at the inclined rollers 8. The attitude adjustment conveyor belt 1 forms a horizontal conveying surface 3 at both ends, which does not affect the normal input and output of the optical modem. The different arrangement heights at both ends of the inclined rollers 8 can form the attitude adjustment plane 2.

[0036] Furthermore, each inclined roller 8 corresponds to two pressing shafts 11, which are respectively arranged at both ends of the inclined roller 8. The pressing shafts 11 are rotatably connected to the conveyor frame 5. The pressing shafts 11 are located above the inclined roller 8 and squeeze the conveyor belt 10. The conveyor belt 10 is restricted between the inclined roller 8 and the pressing shafts 11, so that the conveyor belt 10 forms a stable attitude adjustment plane 2 at the inclined roller 8, which is used to adjust the position of the optical modem during the conveying process, so that the color mark on the side wall of the optical modem is within the detection range of the color sensor 4.
