Description

Technical Field

[0001] This utility model relates to the field of appearance inspection technology, and in particular to a multi-angle appearance inspection platform. Background Technology

[0002] Traditional visual inspection often uses horizontal transmission to inspect multiple objects. During inspection, the inspection angle is relatively singular, the inspection accuracy is low, or multiple sets of image acquisition devices in different directions need to be set up at the same time to inspect the objects. Furthermore, the inspection angle is fixed and difficult to adjust, and it cannot adapt to the inspection of different types of objects at the same time, resulting in poor versatility.

[0003] To address the aforementioned issues, patent document CN215866344U discloses a multi-angle appearance inspection platform, comprising a flexible carrier for fixing the object to be inspected and a multi-angle rotation mechanism for driving the flexible carrier to achieve multi-angle attitude adjustment. The multi-angle rotation mechanism includes a vertical rotation component that drives the flexible carrier to rotate on a horizontal plane and a horizontal rotation component that drives the vertical rotation component to rotate on another horizontal plane. The object to be inspected is fixed onto the flexible carrier, and the vertical and horizontal rotation components drive the object to be inspected to adjust its attitude relative to the image acquisition device, such as pitching, tilting, and rotating. Multiple image data of different specific attitudes are acquired and uploaded to a host computer for comparison with image data of a standard object in the corresponding attitude. Compared with existing technologies, this improves the accuracy of visual inspection and the versatility of visual inspection equipment by automatically adjusting the attitude of the object to be inspected and acquiring multiple image data of different specific attitudes for comparison.

[0004] Based on the above search and combined with existing technology, it was found that although the existing multi-angle appearance inspection platform can realize multi-angle appearance inspection, it requires secondary loading to complete the full inspection. That is, the object to be inspected needs to be inspected once, then removed, flipped, and placed on the flexible carrier again for inspection of the clamped surface. This makes the inspection efficiency of a single object low. Therefore, a multi-angle appearance inspection platform is needed. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example: Reference Figures 1-3 The multi-angle appearance inspection platform shown includes a base 1, an inspection cover 2 is fixedly installed on the upper end of the base 1, and an opening 211 is opened on one side of the inspection cover 2.

[0036] A set of electric grippers 3 is rotatably connected to the side of the detection cover 2 away from the opening 211, and another set of electric grippers 3 is movably arranged on the outside of the opening 211 of the detection cover 2. The two sets of electric grippers 3 are arranged in a mirror image.

[0037] A movable mounting plate 4 for supporting another set of electric grippers 3 is slidably installed on the upper end of the base 1. An electric push rod 8 is provided on one side of the movable mounting plate 4 to drive the movable mounting plate 4 to slide horizontally along the base 1. When the electric push rod 8 drives the movable mounting plate 4 to slide horizontally, it drives the other set of electric grippers 3 to extend into the detection cover 2 or move to the outside of the detection cover 2.

[0038] Three detection cameras 9 are fixedly installed inside the detection cover 2. One detection camera 9 is located at the top inside the detection cover 2, and the other two detection cameras 9 are located on both sides of the detection cover 2 and above the electric grippers 3. The detection camera 9 located above one set of electric grippers 3 is tilted toward another set of electric grippers 3, and the detection camera 9 located above another set of electric grippers 3 is tilted toward one set of electric grippers 3.

[0039] The base 1 is also equipped with a drive mechanism that drives the two sets of electric grippers 3 to rotate synchronously and in the same direction.

[0040] Based on the above structure, when inspecting an object's appearance, the operator only needs to first use another set of electric grippers 3 to hold the object, and then activate the electric push rod 8. The electric push rod 8, through the movable mounting plate 4, drives the other set of electric grippers 3 to extend into the inspection cover 2. At this time, the drive mechanism drives the two sets of electric grippers 3 to rotate synchronously, causing the object held in the other set of electric grippers 3 to rotate. During rotation, the inspection camera 9 located at the top of the inspection cover 2 and the inspection camera 9 located at the top of one set of electric grippers 3 simultaneously acquire images of the object's periphery and one end. Then, the electric push rod 8 is activated again. The object is brought closer to one side of a set of electric grippers 3 and held by the set of electric grippers 3. Then the other set of electric grippers 3 releases and moves away from the object, and the object rotates again. At this time, the detection camera 9 located on the upper end of the other set of electric grippers 3 captures an image of the other end of the object. Thus, only the image capture between the two sides needs to be changed, without the need to reload the object after unloading. Moreover, the object does not need to be rotated within a large deflection range during detection. The overall structure is compact, and the detection speed is significantly improved compared to the existing technology, which can improve the detection efficiency when using this multi-angle appearance inspection platform to perform appearance inspection on objects.

[0041] Furthermore, the detection cover 2 includes a hemispherical cover 21 and a flat bottom 22. The hemispherical cover 21 is a hemispherical cover body, and the flat bottom 22 is a flat plate that forms a circular bottom that fits the lower part of the hemispherical cover 21. An opening 211 is opened on one side of the hemispherical cover 21, and the three detection cameras 9 are all fixed inside the hemispherical cover 21.

[0042] The hemispherical cover 21 is a light-emitting cover with a built-in light source, thereby forming a full-angle illumination condition without shadows, which makes it easier for the detection camera 9 to collect more accurate appearance images. The outer side of the hemispherical cover 21 is a shell made of opaque material.

[0043] A light-absorbing layer 221 coated with a light-absorbing paint is formed on the upper surface of the flat bottom 22, thereby eliminating the reflection of light by the flat bottom 22 and preventing the reflected light from interfering with the image acquisition of the detection camera 9.

[0044] Furthermore, a set of electric grippers 3 are rotatably connected to one side of the hemispherical cover 21 via a fixed short shaft 31, and the fixed short shaft 31 rotates through the hemispherical cover 21 and extends to the outside;

[0045] Another set of electric grippers 3 is rotatably connected to the movable mounting plate 4 via a movable long shaft 32;

[0046] The base 1 has a groove 11 at its upper end, and the movable mounting plate 4 has a slider 41 that is slidably connected to the groove 11 at its lower end. The piston rod end of the electric push rod 8 is fixed to the lower part of the movable mounting plate 4.

[0047] Furthermore, the drive mechanism includes:

[0048] Drive motor 5 is fixed to one side of base 1;

[0049] Drive shaft 6, one end of drive shaft 6 is connected to the output shaft of drive motor 5, and drive shaft 6 is rotatably connected to base 1 through support block 12;

[0050] The transmission component 7 is provided in two sets. The drive shaft 6 drives the fixed short shaft 31 and the movable long shaft 32 to rotate through the two sets of transmission components 7 respectively.

[0051] After the drive motor 5 starts, it can drive the fixed short shaft 31 and the movable long shaft 32 to rotate synchronously and in the same direction through the drive shaft 6 and two sets of transmission components 7. This, in turn, drives the two sets of mirror-set electric grippers 3 to rotate synchronously and in the same direction, so that the two sets of electric grippers 3 always maintain the same clamping angle. Therefore, when the two sets of electric grippers 3 are exchanging gripping objects, there is no need to recalibrate, ensuring smooth exchange of objects between the two sets of electric grippers 3 and reducing the calibration time required when exchanging gripping objects at both ends.

[0052] Furthermore, drive shaft 6 includes:

[0053] A sleeve 61 is fixed at one end to the output shaft of the drive motor 5, and a rear square slot is provided at the end of the sleeve 61 away from the drive motor 5.

[0054] The movable shaft head 62 is rotatably connected to one side of the movable mounting plate 4 via the side support plate 42, and the movable shaft head 62 is driven and slidably connected to the sleeve shaft 61 via the square shaft 63.

[0055] One set of transmission components 7 is installed on the sleeve shaft 61 and drives the fixed short shaft 31 to rotate, while the other set of transmission components 7 is installed on the movable shaft head 62 and drives the movable long shaft 32 to rotate.

[0056] Each set of transmission components 7 includes a transmission wheel 71 and a transmission belt 72. There are two transmission wheels 71, which are respectively sleeved on the fixed short shaft 31 and the sleeve shaft 61. The transmission belt 72 is sleeved between the two transmission wheels 71.

[0057] The drive shaft 6 is configured as a telescopic transmission shaft, so that the drive shaft 6 can extend and retract with the movement of another set of electric grippers 3, while maintaining its transmission effect, thus meeting the requirement of simultaneously driving the two sets of electric grippers 3 to rotate synchronously in the same direction.

[0058] The working principle of this utility model is as follows: In daily use, the operator only needs to first use another set of electric grippers 3 to clamp the object, and then start the electric push rod 8. The electric push rod 8 drives the other set of electric grippers 3 to extend into the detection cover 2 through the movable mounting plate 4. At this time, the drive mechanism drives the two sets of electric grippers 3 to rotate synchronously. Specifically, after the drive motor 5 starts, it drives the fixed short shaft 31 and the movable long shaft 32 to rotate synchronously in the same direction through the drive shaft 6 and the two sets of transmission components 7. This drives the two sets of mirror-set electric grippers 3 to rotate synchronously in the same direction, so that the object clamped on the other set of electric grippers 3 rotates. During the rotation, the detection camera 9 located at the top of the detection cover 2 and the detection camera located at the top of the electric grippers 3 rotate simultaneously. Camera 9 simultaneously captures images of the object's periphery and one end. Then, the electric push rod 8 is activated again, causing the object to move closer to one side of a set of electric grippers 3. The object is then gripped by one set of electric grippers 3, and then the other set of electric grippers 3 releases and moves away from the object. The object rotates again, and at this time, the detection camera 9 located on top of the other set of electric grippers 3 captures images of the other end of the object. Thus, only the image capture between the two sides needs to be switched, eliminating the need to reload the object after unloading. Furthermore, the object does not need to be rotated within a large deflection range during detection. The overall structure is compact, and the detection speed is significantly improved compared to existing technologies, thereby enhancing the detection efficiency when using this multi-angle appearance inspection platform to perform appearance inspection on objects.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
