[0002] The production process of optical communication products involves the assembly of materials. Some materials need to use an angle adjustment system to adjust their rotation angle before assembly to facilitate subsequent assembly, such as transistor particles. The existing technology uses a visual recognition mechanism to identify the material, and then uses a rotation mechanism to drive the manipulator to adjust the rotation angle of the crystal particles according to the recognition information of the visual recognition mechanism.

[0003] Since positive light recognition is not conducive to the visual recognition mechanism to identify the characteristics of the material, the existing technology needs to use backlight recognition to identify the characteristics of the material, that is, it is necessary to fill light on one side of the material and take a photo on the other side of the material. Since the robot will interfere with backlight recognition, the existing technology also requires the robot to first move the material and place it on the recognition station, and then use the robot to pick up the material again after the recognition is completed, and then adjust the angle. The steps are cumbersome and the efficiency is very low, resulting in high production costs. Utility Model Content

[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0033] The present utility model embodiment provides an angle adjustment system 1000, such as Figure 1-Figure 3 As shown, the angle adjustment system 1000 has a loading station and a visual recognition station. The angle adjustment system 1000 includes a vacuum suction cup 100, a light source 200, a position adjustment mechanism 300, a visual recognition mechanism 400 and a rotating mechanism 500. The vacuum suction cup 100 is made of a light-transmitting material. The light source 200 is installed on the top of the vacuum suction cup 100. The position adjustment mechanism 300 is connected to the vacuum suction cup 100 and is used to drive the vacuum suction cup 100 to move to the loading station and the visual recognition station. The visual recognition mechanism 400 is arranged at the visual recognition station and is located at the bottom of the vacuum suction cup 100. The rotating mechanism 500 is connected to the vacuum suction cup 100 and is in communication connection with the visual recognition mechanism 400, so that the rotating mechanism 500 can drive the vacuum suction cup 100 to rotate according to the feedback information of the visual recognition mechanism 400.

[0034] The operation process of the angle adjustment system 1000 of this embodiment is as follows:

[0035] S101: Using the position adjustment mechanism 300 to move the vacuum suction cup 100 to the loading station;

[0036] S102: Pick up the material at the loading station using the vacuum suction cup 100;

[0037] S103: using the position adjustment mechanism 300 to move the vacuum suction cup 100 from the loading station to the visual recognition station;

[0038] S104: using the light source 200 and the visual recognition mechanism 400 to complete backlight recognition of the material;

[0039] S105: The rotating mechanism 500 drives the vacuum suction cup 100 to rotate according to the feedback information of the visual recognition mechanism 400, thereby adjusting the rotation angle of the material.

[0040] Specifically, since the light source 200 is installed on the top of the vacuum suction cup 100 and the visual recognition mechanism 400 is located at the bottom of the vacuum suction cup 100, when the vacuum suction cup 100 is moved to the visual recognition station by the position adjustment mechanism 300, the light source 200 and the visual recognition mechanism 400 will be respectively located on the top and bottom sides of the vacuum suction cup 100. Because the vacuum suction cup 100 is light-transmitting, it will not block the light emitted by the light source 200 and will not interfere with backlight recognition. Therefore, by implementing this embodiment, the visual recognition mechanism 400 and the light source 200 can be used to perform backlight recognition on the material without placing the material. Unlike the prior art, there is no need to place the material on the visual recognition station first and then pick up the material again after the backlight recognition is completed. Therefore, the angle adjustment system 1000 provided in this embodiment can greatly reduce the time consumed for backlight recognition, improve the working efficiency of the angle adjustment system 1000, and reduce production costs.

[0041] In a specific embodiment, the vacuum suction cup 100 is made of transparent silicone to allow the vacuum suction cup 100 to be light-transmissive, so that the vacuum suction cup 100 will not block the light emitted by the light source 200 and will not interfere with backlight recognition.

[0042] refer to Figure 4 In some embodiments, the loading station and the visual recognition station are arranged in a first horizontal direction (reference Figure 4 The position adjustment mechanism 300 is sequentially arranged in the X direction, and includes a first translation assembly 310, the first translation assembly 310 is connected to the vacuum suction cup 100, and the first translation assembly 310 is used to drive the vacuum suction cup 100 to move in the first horizontal direction.

[0043] Since the loading station and the visual recognition station are arranged in sequence in the first horizontal direction, and the first translation assembly 310 is used to drive the vacuum suction cup 100 to move in the first horizontal direction, the first translation assembly 310 can drive the vacuum suction cup 100 to move to the loading station and the visual recognition station. Specifically, when the vacuum suction cup 100 needs to be used to pick up materials, the first translation assembly 310 can drive the vacuum suction cup 100 to move to the loading station to pick up materials. When backlight recognition is required, the first translation assembly 310 can drive the vacuum suction cup 100 with the material adsorbed to move to the visual recognition station, and use the light source 200 and the visual recognition mechanism 400 for backlight recognition.

[0044] refer to Figure 4 , Figure 5 In a specific embodiment, the position adjustment mechanism 300 further includes a lifting component 320 , which is connected to the vacuum suction cup 100 to drive the vacuum suction cup 100 to rise and fall.

[0045] The operation process of the angle adjustment system 1000 of this embodiment is as follows:

[0046] S201: Using the first translation assembly 310 to drive the vacuum suction cup 100 to move to the first working position;

[0047] S202: Using the lifting assembly 320 to drive the vacuum suction cup 100 to descend and absorb the material;

[0048] S203: Using the lifting assembly 320 to drive the vacuum suction cup 100 to rise;

[0049] S204: Using the first translation assembly 310 to drive the vacuum suction cup 100 to move to the visual recognition station;

[0050] S205: using the light source 200 and the visual recognition mechanism 400 to complete backlight recognition of the material;

[0051] S206: The rotating mechanism 500 drives the vacuum suction cup 100 to rotate according to the feedback information of the visual recognition mechanism 400, thereby adjusting the rotation angle of the material.

[0052] By implementing this embodiment, the vacuum suction cup 100 has the ability to lift and lower, which can prevent the vacuum suction cup 100 from touching the side of the material when moving to the first station, and can also prevent the bottom of the material from being scratched when the material is moved away from the loading station.

[0053] refer to Figure 4 , Figure 5 In a specific embodiment, the lifting assembly 320 includes a first rotating motor 321, a first screw rod 322, a first movable seat 323 and a first guide seat 324. The first rotating motor 321 is connected to the first screw rod 322 to drive the first screw rod 322 to rotate; the first movable seat 323 is in the direction of gravity (reference Figure 4 The first movable seat 323 is provided with a first threaded hole, and the first screw rod 322 is passed through the first threaded hole; the first movable seat 323 is connected to the suction cup.

[0054] Specifically, when the first rotating motor 321 drives the first screw rod 322 to rotate, the first screw rod 322 will cooperate with the first threaded hole on the first movable seat 323, thereby driving the first movable seat 323 to rise and fall. Since the first movable seat 323 is connected to the suction cup, the lifting of the first movable seat 323 will drive the suction cup to rise and fall. The first guide seat 324 can provide a guide for the first movable seat 323, ensuring that the first movable seat 323 can only move relative to the first guide seat 324 in the direction of gravity. In this way, when the first screw rod 322 rotates, it will only rotate relative to the first movable seat 323, and will not drive the first movable seat 323 to rotate together, so that the displacement accuracy of the first movable seat 323 can be guaranteed.

[0055] refer to Figure 5In a specific embodiment, the lifting assembly 320 further includes a mounting seat 325 , which is connected to the first guide seat 324 , and one end of the first screw rod 322 is connected to the first rotating motor 321 , and the other end is rotatably connected to the mounting seat 325 .

[0056] Specifically, since one end of the first screw rod 322 is connected to the first rotary motor 321 and the other end is far away from the first rotary motor 321, the other end of the first screw rod 322 is less constrained by the first rotary motor 321. If no additional constraint is added to the other end of the first screw rod 322, the first screw rod 322 will have a swinging tendency when rotating, and the swinging tendency will increase the friction between the first threaded hole and the first screw rod 322, thereby affecting the service life of the lifting assembly 320. In order to solve this technical problem, the lifting assembly 320 of this embodiment also includes a mounting seat 325 connected to the first guide seat 324, and the other end of the first screw rod 322 is rotatably connected to the mounting seat 325, so that both ends of the first screw rod 322 are constrained, thereby reducing the friction between the first threaded hole and the first screw rod 322, which is conducive to improving the service life of the lifting assembly 320.

[0057] refer to Figure 6 In a specific embodiment, the first guide seat 324 is provided with a first recessed rail 3241 extending in the direction of gravity, and the first movable seat 323 is provided with a first protrusion 3231 accommodated in the first recessed rail 3241, so that the first movable seat 323 is slidably connected to the first guide seat 324 in the direction of gravity.

[0058] Furthermore, two first concave rails 3241 are provided, and the two first concave rails 3241 are symmetrically arranged on opposite sides of the first guide seat 324, and two first protrusions 3231 are correspondingly provided, so that the first guide seat 324 can provide a more stable guiding effect when the first movable seat 323 is displaced.

[0059] refer to Figure 4 , Figure 7 In some embodiments, the position adjustment mechanism 300 further includes a second translation assembly 330, and the second translation assembly 330 is connected to the vacuum suction cup 100 to drive the vacuum suction cup 100 in the second horizontal direction (reference Figure 4 The second horizontal direction moves in the Y direction, and the second horizontal direction is perpendicular to the first horizontal direction.

[0060] Specifically, when the second translation assembly 330 is not provided, the adsorption position of the vacuum suction cup 100 in the second horizontal direction is fixed, so there will be requirements for the material loading position, specifically, it is necessary to ensure that when the material is placed at the loading station, the material corresponds to the position of the vacuum suction cup 100 in the second horizontal direction, so the adaptability of the angle adjustment system 1000 is relatively poor. In order to solve this technical problem, the position adjustment mechanism 300 of this embodiment is additionally provided with a second translation assembly 330, and the second translation assembly 330 is connected to the vacuum suction cup 100 to drive the vacuum suction cup 100 to move in the second horizontal direction. In this way, when the material is placed at the loading station, even if it does not correspond to the position of the vacuum suction cup 100 in the second horizontal direction, the second translation assembly 330 can be used to drive the vacuum suction cup 100 to move, so that the vacuum suction cup 100 corresponds to the position of the material in the second horizontal direction.

[0061] refer to Figure 4 In a specific embodiment, the second translation assembly 330 is installed on the first translation assembly 310 , and the stroke of the first translation assembly 310 is greater than that of the second translation assembly 330 .

[0062] Specifically, since the stroke of the first translation assembly 310 is greater than that of the second translation assembly 330, compared with the embodiment in which the first translation assembly 310 is installed on the second translation assembly 330, installing the second translation assembly 330 on the first translation assembly 310 can effectively reduce the shaking of the position adjustment mechanism 300 during operation and increase the stability of the position adjustment mechanism 300 during operation.

[0063] refer to Figure 7 In some embodiments, the second translation assembly 330 includes a second rotary motor 331, a second screw rod 332, a second movable seat 333, and a second guide seat 334. The second rotary motor 331 is connected to the second screw rod 332 to drive the second screw rod 332 to rotate; the second movable seat 333 is slidably connected to the second guide seat 334 in the second horizontal direction; the second movable seat 333 is provided with a second threaded hole, and the second screw rod 332 is passed through the second threaded hole; the second movable seat 333 is connected to the suction cup.

[0064] Specifically, when the second rotary motor 331 drives the second screw rod 332 to rotate, the second screw rod 332 will cooperate with the second threaded hole on the second movable seat 333, thereby driving the second movable seat 333 to move in the second horizontal direction. Since the second movable seat 333 is connected to the suction cup, the second movable seat 333 will drive the suction cup to move in the second horizontal direction. The second guide seat 334 can provide a guide for the second movable seat 333, ensuring that the second movable seat 333 can only move relative to the second guide seat 334 in the second horizontal direction. In this way, when the second screw rod 332 rotates, it will only rotate relative to the second movable seat 333, and will not drive the second movable seat 333 to rotate together, so that the displacement accuracy of the second movable seat 333 can be guaranteed.

[0065] refer to Figure 8 In a specific embodiment, the second guide seat 334 is provided with a second recessed rail 3341 arranged along the second horizontal direction, and the second movable seat 333 is provided with a second protrusion 3331 accommodated in the second recessed rail 3341, so that the second movable seat 333 is slidably connected to the second guide seat 334 in the second horizontal direction.

[0066] Furthermore, two second concave rails 3341 are provided, and the two second concave rails 3341 are symmetrically arranged on opposite sides of the second guide seat 334, and two second protrusions 3331 are correspondingly provided, so that the second guide seat 334 can provide a more stable guiding effect when the second movable seat 333 is displaced.

[0067] refer to Figure 4 In some embodiments, the lifting assembly 320 is mounted on the second translation assembly 330 , and the stroke of the second translation assembly 330 is greater than the stroke of the lifting assembly 320 .

[0068] Specifically, since the stroke of the second translation assembly 330 is greater than the stroke of the lifting assembly 320, compared with the embodiment in which the second translation assembly 330 is installed on the lifting assembly 320, installing the lifting assembly 320 on the second translation assembly 330 can effectively reduce the shaking of the position adjustment mechanism 300 during operation and increase the stability of the position adjustment mechanism 300 during operation.

[0069] refer to Figure 2 , Figure 4 In a specific embodiment, the vacuum suction cup 100 is mounted on a rotating mechanism 500 , and the rotating mechanism 500 is mounted on a lifting assembly 320 .

[0070] This embodiment shows a most preferred implementation of the position adjustment mechanism 300, specifically, the vacuum suction cup 100 is installed on the rotating mechanism 500, the rotating mechanism 500 is installed on the lifting assembly 320, the lifting assembly 320 is installed on the second translation assembly 330, and the second translation assembly 330 is installed on the first translation assembly 310. With such an arrangement, the position adjustment mechanism 300 has the best stability during operation.

[0071] In some embodiments, the angle adjustment system 1000 also has a loading station, and the loading station, visual recognition station and unloading station are arranged in sequence in the first horizontal direction, so that the first translation component 310 can drive the vacuum suction cup 100 to move to the loading station, visual recognition station and unloading station.

[0072] Specifically, after the backlight recognition is completed, the first translation component 310 can be used to drive the vacuum suction cup 100 to move to the unloading station for unloading. The rotating mechanism 500 can adjust the material rotation angle at the visual recognition station, and can also adjust the material position during the process of the first translation component 310 driving the vacuum suction cup 100 to move to the unloading station. The material rotation angle can also be adjusted at the unloading station. This embodiment is not limited here.

[0073] Optionally, after the angle adjustment is completed, a transportation device will transport the material to the next process. The transportation system can be configured to directly obtain the material from the visual recognition station of the angle adjustment system 1000. In this way, the angle adjustment system 1000 does not need to set up a material unloading station.

[0074] refer to Figure 3 In some embodiments, a connection port 110 is provided on the side of the vacuum suction cup 100, and the connection port 110 is used to connect to a negative pressure device, so that when the negative pressure device is running, the vacuum suction cup 100 can generate suction to absorb materials.

[0075] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present utility model.
