The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1, in some embodiments, the inspection apparatus 10 includes a fixture 11, an excitation assembly 12, a reflection assembly 13, and an image capturing device 14, the fixture 11 is used for carrying a product 20, the excitation assembly 12 is used for changing a medium, the reflection assembly 13 includes a frame 131 and a plurality of prisms 132 mounted on the frame 131, the prisms 132 are disposed along an outer circumference of the frame 131 and are used for reflecting portions to be inspected of the product 20 at a plurality of angles through the prisms 132, and the image capturing device 14 is used for acquiring images of the portions to be inspected of the product 20 at a plurality of angles, so as to complete inspection of the product through the images.

The method for detecting the portion to be detected according to the image can be implemented by an image recognition technology according to the detection requirement, which is not described herein again, and an example of the image is shown in fig. 3.

Optionally, the image capturing element 14 has an optical axis 141, and the jig 11, the excitation element 12, the reflection element 13 and the image capturing element 14 are disposed along the optical axis 141. The jig 11, the excitation component 12, the reflection component 13, and the image capturing element 14 may be sequentially disposed along the optical axis 141, or the jig 11, the reflection component 13, the excitation component 12, and the image capturing element 14 may be sequentially disposed along the optical axis 141, or the excitation component 12, the jig 11, the reflection component 13, and the image capturing element 14 may be sequentially disposed along the optical axis 141, or the excitation component 12, the jig 11, the image capturing element 14, and the reflection component 13 may be sequentially disposed along the optical axis 141, but is not limited thereto. For convenience of illustration, the jig 11, the excitation element 12, the reflection element 13 and the image capturing element 14 are sequentially disposed along the optical axis 141 in the present embodiment for illustration, but not limited thereto.

In the detecting device 10, the exciting assembly 12 can change the state of the medium on the product 20, and the prisms 132 can reflect the portion of the product 20 to be detected at multiple angles on the same side wall, so that the image capturing unit 14 can obtain the images of the portion of the product 20 to be detected at multiple angles on one side wall of the product 20 only by one-time imaging, so as to complete the product detection through the images, thereby improving the efficiency of detecting the product 20.

In some embodiments, referring to fig. 1, a rectangular coordinate system is established for ease of illustration. In some embodiments, the optical axis is on the Y-axis. The "position" is exemplified as a point position of a feature point (e.g., a center of gravity, a center of a key plane, etc.) of the product 20 or the sidewall in a coordinate system, and may be expressed by (x, y, z). In this embodiment, the center of the surface where the side wall to be detected is located is taken as the position. The "attitude" is exemplified by an angle at which a center line of the product 20 or the sidewall is deflected from coordinate axes in a coordinate system, and may be expressed by (α, β, γ), where α may represent an angle at which a projection of the center line is rotated with respect to an X axis in an XZ plane, β may represent an angle at which a projection of the center line is rotated with respect to a Y axis in an XY plane, and γ may represent an angle at which a projection of the center line is rotated with respect to a Z axis in a YZ plane. "pose" is exemplified by a combination of "position" and "attitude", and can be expressed by (x, y, z, α, β, γ). Since the optical axis of the image capturing element 14 is also on the coordinate system, the relative position, posture or pose of the product and the optical axis can be expressed by the coordinate system.

The jig 11 may include a carrier 111 and a transferring member 112 connected to the carrier 111 for adjusting the position, posture or pose of the carrier 111. For example, the transfer member 112 can drive the carrying seat 111 to move horizontally or rotationally. The carrying seat 111 is used for carrying and fixing the product 20, and the transferring member 112 is used for driving the carrying seat 111 to drive the product 20 to move so as to adjust a position, a posture or a pose required by the product 20. In the present embodiment, the transfer unit 112 in the jig 11 converts the input power, for example, the power input through the motor and the transmission unit, into the force for moving the carrier base 111, and adjusts the position, posture or attitude of the product 20 as required. Optionally, the movement direction of the carrying seat 111 for carrying the product 20 may include movement along the X-axis, rotation around the Z-axis, or combination of two or three movement manners. For example, the operator can obtain the images of all the portions to be measured by the image capturing device 14 by finding that the products 20 on the carrying seat 111 need to be adjusted by a certain distance in the positive direction of the X axis through the image capturing device 14, and then the carrying seat 111 can be driven by the moving and carrying device 112 to be adjusted by a certain distance in the positive direction of the X axis. For another example, when the side wall (for example, the side wall corresponding to the first side 21 in fig. 1) of the product 20 is detected, and the operator needs to adjust to another side wall to continue the detection (for example, the side wall corresponding to the second side 22 or the fourth side 24 in fig. 1), the operator may control the moving and carrying member 112 to drive the carrying seat 111 to rotate clockwise or counterclockwise by 90 degrees along the Z axis until the image capturing member 14 can obtain an image of the another side wall including the portion to be detected. It can be understood that the above-mentioned image capturing element 14 obtains images of the portion to be measured under multiple angles of the product through the position change of the carrying seat 111.

In some embodiments, to achieve the "changeable state" effect, the medium may comprise a fluorescent agent and the excitation member 122 is an ultraviolet lamp. Thus, the fluorescent agent on the product 20 can change the state of the light emitting effect or the visible effect after being irradiated by the ultraviolet light, and further can be acquired by the image capturing element 14, so that an obviously visible image is obtained. The excitation assembly 12 may be a thermal excitation device and the state-changeable medium may be a thermal medium, but is not limited thereto, as long as the medium is changed to a state that is clearly visible on the image after being excited by the excitation assembly 12. For convenience of description, the excitation assembly 12 is taken as an excitation member, and the medium is taken as a fluorescent medium. This approach is low cost and has significant effect on changing the state, but is not limited thereto.

In other embodiments, the detection purpose is to detect the glue overflow condition of the product 20 on the sidewall, as shown in fig. 1, the portion to be detected may include an image of glue on the product 20 and in the Z direction, which is dotted on the first edge 21, the second edge 22, the third edge 23 and the fourth edge 24, or may be an image of holes in the outer sidewall of the first edge 21, the inner sidewall of the second edge 22, the third edge 23 and the fourth edge 24, which have been subjected to glue dispensing.

As shown in fig. 3, taking the first side 21 as an example, the glue with the medium filled in the hole on the first side 21 is irradiated by the exciting member and then displayed as the identification feature 30 in the image, and the purpose of detecting the defect of the product 20 is achieved according to the identification feature 30 and the image. In this case or equivalently, in the case where the detection of the outside of the product 20 is not required, the determination of the defect of the product 20 can be performed without moving or rotating the jig 11, i.e. the product 20 is in only one fixed position on the jig 11, and the adjustment of the prisms 132 of the reflection assembly 13 is required to obtain the portion of the product 20 to be measured on all the side walls. One way to determine whether the product 20 has defects is as follows: when the part to be detected is the images of the glue on the product 20 and in the Z direction, which are dotted on the first edge 21, the second edge 22, the third edge 23 and the fourth edge 24, the images are judged to exceed the highest point of the first edge 21, the second edge 22, the third edge 23 and the fourth edge 24 in the Z direction, or the part to be detected is the images of the holes in the inner side walls of the first edge 21, the second edge 22, the third edge 23 and the fourth edge 24, which are subjected to glue dispensing, and the images are judged to exceed the preset area range, the product 20 is judged to have the glue overflow defect, otherwise, the product 20 is judged not to have the glue overflow defect, and the description is omitted. It is understood that the image capturing element 14 obtains images of the first side 21, the second side 22, the third side 23 and the fourth side 24 at corresponding angles by reflection through the plurality of prisms 132.

With continued reference to fig. 2, in some embodiments, frame 131 has a frame through slot 1311 and a plurality of mounting slots 1312, where frame through slot 1311 penetrates frame 131 along optical axis 141, and a plurality of mounting slots 1312 are disposed along the outer circumference of frame 131 and respectively communicate with frame through slot 1311, and each prism 132 is disposed in mounting slot 1312 and connected to frame 131. It is understood that the frame through groove 1311 is provided at the outer circumference thereof with a plurality of prisms 132.

In this embodiment, the number of the mounting grooves 1312 and the prisms 132 is four, and the frame 131 has a hollow rectangular parallelepiped structure.

In some embodiments, prism 132 is rotatably coupled to frame 131, and the central axis of rotation of prism 132 is not coincident with optical axis 141. In this embodiment, the rotation mode of the prism 132 and the frame 131 is a thread rotation mode, which is convenient for adjusting with higher precision and can effectively fix the deflection angle between the prism 132 and the frame 131, and is also convenient for adjusting when the detection device 10 is applied to products of different specifications. Alternatively, the central axis of rotation of each prism 132 is perpendicular to the optical axis 141.

Therefore, the position of the prism 132 relative to the jig 11 can be conveniently adjusted, and the angle of the prism 132 reflecting the product on the jig 11 can be further changed, so that the to-be-detected part of the product 20 can change the state through the plurality of prisms 132 at one time.

With continued reference to fig. 2, in some embodiments, the reflection assembly 13 further includes an adjustment member 133, and the prism 132 is rotatably connected to the lens frame 131 through the adjustment member 133.

In this embodiment, the adjusting member 133 may be a locking bolt, the adjusting member 133 is movably clamped on the frame 131, the prism 132 is provided with a threaded hole 1321, the adjusting member 133 is connected to the threaded hole 1321 to rotatably connect the prism 132 and the frame 131, and meanwhile, the prism 132 and the frame 131 can be rotatably connected.

In other embodiments, the frame 131 may also have a plurality of retaining protrusions, the prism 132 has retaining grooves matching with the retaining protrusions, and the adjusting member 133 may be a structure formed by the retaining protrusions and the retaining grooves, and the prism 132 and the frame 131 are rotatably connected by the retaining protrusions and the retaining grooves.

In some embodiments, each prism 132 has a triangular cross-section, and optionally each prism 132 is a triangular prism. An image of a feature to be measured (e.g., the first edge 21) in the portion to be measured is acquired by the image capturing element 14 after passing through a corresponding one of the prisms 132. Thus, the triangular cross-sectional structure enables the prism 132 to have a larger angle adjustment range, so that the prism 132 has a better application range, and further, the to-be-measured portions of the product 20 related to the first side 21, the second side 22, the third side 23 and the fourth side 24 can be clearly concentrated in the field of view or the field of view of the image capturing element 14.

In some embodiments, the excitation assembly 12 includes a mount 121 and a plurality of excitations 122. The mounting base 121 is disposed between the reflection assembly 13 and the fixture 11 and has a mounting through groove 121a, the mounting through groove 121a penetrates through the mounting base 121 along the optical axis 141, the plurality of excitation members 122 are connected to one side of the mounting base 121 facing the fixture 11, and the plurality of excitation members 122 are disposed along the peripheral side of the mounting through groove 121a. Thus, the plurality of excitation members 122 form an annular structure matching the shape of the product, so that the light can better cover the side wall of the product 20 on the fixture 11. Alternatively, the ring structure formed by the plurality of excitation members 122 may be a circular ring shape, a rectangular shape, or a polygonal ring shape.

Referring to fig. 2, in the present embodiment, the mounting seat 121 is composed of a bottom plate 1211 and a mounting plate 1212 connected to the bottom plate 1211, and the mounting plate 1212 is in a hollow ring shape, wherein the hollow structure of the mounting plate 1212 forms the mounting through groove 121a.

Further, the mounting plate 1212 is provided with a first recess 1212a opening toward the jig 11, and the plurality of excitation elements 122 are connected to a bottom wall of the first recess 1212a and received in the first recess 1212 a. In this manner, failure due to accidental impact of the excitation member 122 can be avoided while adjusting the excitation assembly 12 for better imaging.

Further, the excitation member 122 is threadably coupled to the mounting plate 1212 to form a detachable coupling between the excitation member 122 and the mounting plate 1212, and the number of excitation members 122 and the spacing between adjacent excitation members 122 can be set according to the desired intensity of the marker light.

In some embodiments, the detecting device 10 further includes a light supplement assembly 15, and the light supplement assembly 15 is disposed between the image capturing element 14 and the product 20, and is used for emitting light different from the light emitted by the exciting assembly 12 toward the product 20, so as to improve the imaging quality of the image. Illustratively, the light emitted from the fill light assembly 15 is white light.

Referring to fig. 1 and fig. 2, in some embodiments, the light supplement assembly 15 includes a light supplement base 151 and a plurality of light supplement lamps 152. The light supplementing base 151 is disposed between the image capturing element 14 and the reflection assembly 13 and has a light supplementing through groove 1511, the light supplementing through groove 1511 penetrates through the light supplementing base 151 along the optical axis 141, the light supplementing lamps 152 are connected to one side of the light supplementing base 151 facing the fixture 11, and the light supplementing lamps 152 are disposed along the peripheral side of the light supplementing through groove 1511 and used for emitting white light toward the product 20. The fill light 152 is illustratively a white LED light.

In this embodiment, the light supplement base 151 is provided with a second groove 1512 with an opening facing the reflection assembly 13, and the light supplement lamp 152 is connected to the bottom wall of the second groove 1512 and is accommodated in the second groove 1512. Thus, when the light supplement assembly 15 is moved, the failure caused by the collision of the light supplement lamp 152 can be avoided.

Further, the light supplement lamp 152 is connected to the light supplement base 151 through a screw thread, so that the light supplement lamp 152 and the light supplement base 151 can be detachably connected, and the number of the light supplement lamps 152 and the distance between the adjacent light supplement lamps 152 can be set according to the required light supplement intensity.

Therefore, the white light emitted by the light supplement component 15 can enhance the brightness of the product 20, and the contrast in the image cannot meet the requirement of automatically identifying the defect.

In some embodiments, the center of the light supplement through groove 1511, the center of the frame through groove 1311, and the center of the mounting through groove 121a are all located on the optical axis 141. Therefore, the image capturing element, the light supplementing element 15, the reflecting element 13 and the exciting element 12 can be conveniently corrected, the adjusting difficulty is reduced, and the accuracy of obtaining the image to be measured of the product 20 is improved.

Fig. 4 shows the optical path and schematic diagram of the product 20, the prism 132 and the image capturing element 14. Illustratively, the imaging principle of the detection device 10 is as follows: in the drawing, a is an inclination angle between the prism 132 and the optical axis 141, B is an incident angle of the side wall of the product 20 reflected by the prism 132, a is a distance or width between the side walls of the product 20, B is a distance between the product 20 and the prism 132, c is a distance between the image capturing element 14 and the prism 132, and d is a path of the reflected light of the product 20. Of the above 5 parameters, a is a fixed parameter, A and B are adjustable parameters, and B and c are varied according to the variation of A/B. Wherein, a is larger, B is larger, c is required to be larger, when a reaches a certain angle value, the reflected light ray d of the product 20 is parallel to the horizontal direction, the image capturing element 14 cannot capture the image in the prism 132, and the angle value of a is the maximum limit value at this time. Similarly, when B is larger and B is larger, c is larger, and in some embodiments, considering that the product 20 already has a certain pose and the detection device is as small as possible, the value of B is set, and the value of a is adjusted to meet the actual use.

The operation of the detection device 10 is substantially as follows:

firstly, a product 20 with a medium in a variable state is mounted on a jig 11, and the distances between an excitation component 12, a reflection component 13, a light supplement component 15 and an image capturing component 14 are adjusted according to the principle described in fig. 4 for the purpose of obtaining a suitable image; then, the excitation element 122 and the light supplement lamp 152 are turned on, so that the medium on the product 20 changes state under the irradiation of the excitation element, wherein the light supplement lamp 152 can also be turned off according to actual needs; finally, images of the to-be-detected part of the product at multiple angles are acquired through the image capturing device 14, so that the product can be detected through the images.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
