Description

Technical Field

[0001] This application belongs to the field of testing technology, and specifically relates to a testing device and automated equipment. Background Technology

[0002] In automatic screw fastening equipment, it is necessary to detect whether the screws are qualified. In related technologies, a vision component is used to photograph the screw, and the size of the screw is measured based on the captured image and compared with a preset size to determine whether the screw is qualified. However, when the position of the photographing part remains unchanged, only a projected image of the screw in one direction can be captured. If it is necessary to measure the size of the workpiece in other directions, the angle of the workpiece or the position of the photographing part needs to be changed, resulting in low measurement efficiency. Utility Model Content

[0003] In view of the above, it is necessary to provide a detection device and automated equipment that can improve the measurement efficiency of workpieces.

[0004] Embodiments of this application provide a detection device, including a receiving chamber, a transmitting structure, and a vision component. The receiving chamber is provided with an insertion interface configured to allow a workpiece to enter and exit the interior of the receiving chamber; a reflective structure is disposed inside the receiving chamber; the reflective structure is configured to emit imaging light to the side of the workpiece when powered on; the vision component includes an imaging element and a detection module, the imaging element being disposed at one end of the receiving chamber; when the reflective structure is de-energized, the imaging element can capture a projected image of the workpiece along a first direction to form a first image; when the reflective structure is powered on, the imaging element can receive imaging light reflected from the side of the workpiece to form a second image; the detection module is electrically connected to the imaging element to measure the size of the workpiece.

[0005] In the aforementioned detection device, when the reflective structure is not energized, it does not operate, and the imaging component operates to capture a projected image of the workpiece along a first direction, forming a first image. When the reflective structure is energized, it reflects imaging light to the side of the workpiece, and the imaging component receives the reflected imaging light from the side of the workpiece, forming a second image. The detection module measures the dimensions of the workpiece in other directions perpendicular to the first direction using the first image, and measures the dimensions of the workpiece in the first direction using the second image. Compared to the imaging component only capturing a projected image of the workpiece in one direction to measure its dimensions, the reflective structure allows the imaging component to capture images of the workpiece from at least two different positions and form different images, while keeping the positions of the imaging component and the workpiece unchanged. This enables the detection module to measure the dimensions of the workpiece based on these different images, thus obtaining the dimensions of the workpiece in at least two directions. This saves time adjusting the positions of the imaging component or the workpiece and improves the measurement efficiency of the workpiece.

[0006] In some embodiments, the reflective structure includes a first light-emitting element, which is disposed on one side of the insertion interface along a second direction, the second direction being perpendicular to the first direction; the first light-emitting element has a first inclined surface, the first inclined surface forming a first angle α with the first direction, the first angle α being 45°, the first light-emitting element can emit imaging light rays along a direction perpendicular to the first inclined surface to the side of the workpiece, so that the second image is an orthographic projection image of the workpiece along the second direction.

[0007] When the reflective structure is powered on, the first light-emitting element emits imaging light in a direction perpendicular to the first inclined plane. By setting a first included angle α of 45°, the second image captured by the imaging element is a projection of the workpiece along the second direction, so that the detection module can measure the size of the workpiece projected along the second direction in a direction perpendicular to the second direction. The reflective structure is used alternately in the powered-on and powered-off states, and the vision component can form an image of the workpiece in two mutually perpendicular directions and measure the size of the workpiece.

[0008] In some embodiments, the reflective structure includes a first light-emitting element and a second light-emitting element, the second light-emitting element and the first light-emitting element being spaced apart and distributed around the insertion interface; the first light-emitting element is disposed on one side of the insertion interface along a second direction, the first light-emitting element is configured to emit a first imaging light to a first side of the workpiece, the second light-emitting element is configured to emit a second imaging light to a second side of the workpiece, the second light-emitting element and the first light-emitting element work alternately, so that the imaging device receives the first imaging light reflected from the first side or receives the second imaging light reflected from the second side to form different second images.

[0009] When the first light-emitting element is activated, the imaging element receives the first imaging light reflected from the first side to form a second image; when the second light-emitting element is activated, the imaging element receives the second imaging light reflected from the second side to form another second image. By emitting imaging light at different angles to different sides of the workpiece through the first and second light-emitting elements, the imaging element can capture images of different sides of the workpiece to measure the size of the workpiece from different angles.

[0010] In some embodiments, the first light-emitting element has a first inclined surface, which forms a first angle α with the first direction; the second light-emitting element has a second inclined surface, which forms a second angle β with the first direction, and the first angle α and the second angle β are 45°; the first light-emitting element can emit a first imaging ray along a direction perpendicular to the first inclined surface, so that the second image is an orthographic projection image of the workpiece along the second direction; the second light-emitting element is disposed on one side of the insertion interface along a third direction, and the second light-emitting element can emit a second imaging ray along a direction perpendicular to the second inclined surface, so that the second image is an orthographic projection image of the workpiece along the third direction; the third direction is perpendicular to the second direction and the first direction.

[0011] When the first light-emitting element is working, it emits a first imaging ray in a direction perpendicular to the first inclined plane. By setting a first included angle α of 45°, the second image captured by the camera is a projected image of the workpiece along the second direction. When the second light-emitting element is working, it emits a second imaging ray in a direction perpendicular to the second inclined plane. By setting a second included angle β of 45°, the second image captured by the camera is a projected image of the workpiece along the third direction. When used in conjunction with the power-off function of the reflective structure, the vision component can form an image of the workpiece and measure its dimensions in three mutually perpendicular directions.

[0012] In some embodiments, the detection device further includes a light source disposed between the receiving chamber and the photographing workpiece, and configured to provide supplemental light toward the workpiece along the extension direction of the receiving chamber.

[0013] Supplemental light is emitted from the light source towards the workpiece to provide additional illumination for the camera, enabling the camera to clearly capture the workpiece.

[0014] In some embodiments, the detection device further includes a feeding member having an inlet and a dispensing outlet, the inlet being configured to receive a workpiece, the feeding member being configured to convey the workpiece to the dispensing outlet, and the dispensing outlet being configured to provide the workpiece to the dispensing member.

[0015] Workpieces can be fed from the inlet to the feeder and then fed from the feeder's outlet to the feeder. This high degree of automation improves workpiece feeding efficiency.

[0016] In some embodiments, the detection device further includes a baffle that is rotatably disposed on the feeding component to expose or cover the feed inlet.

[0017] When the workpiece model is correct, the baffle rotates and opens, allowing the workpiece to be fed through the inlet. When the workpiece model is incorrect, the baffle rotates and covers the inlet to prevent the incorrect workpiece from being fed. By adding the action of opening or closing the baffle, the operator is reminded to verify the workpiece model.

[0018] In some embodiments, the detection device further includes a drive assembly connected to a baffle and electrically connected to an identification element to drive the baffle to rotate when the identification element identifies a workpiece match.

[0019] The workpiece is identified by an external identification device to verify whether it matches. When the workpiece matches, the baffle is driven to rotate by the drive component to improve the level of automation and prevent the feeder from failing to verify the workpiece.

[0020] In some embodiments, the detection device further includes a demagnetizing element having a demagnetizing inlet, into which a workpiece can be inserted, and the demagnetizing element being configured to demagnetize a workpiece inserted into the demagnetizing inlet.

[0021] Residual magnetism on the workpiece is eliminated by demagnetizing components, thereby improving the quality of the workpiece and preventing magnetic interference with its installation.

[0022] Embodiments of this application also provide an automated device, including the detection apparatus as described in any of the above embodiments.

[0023] In the aforementioned automated equipment, the workpiece is accurately inspected by a detection device before being installed onto the product, thereby controlling the size of the workpiece and improving the product yield and quality. Attached Figure Description

[0031] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0032] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0034] Technical terms such as “first” and “second” are used only to distinguish different objects and should not be interpreted as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features.

[0035] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0036] In automatic screw fastening equipment, it is necessary to detect whether the screws are qualified. In related technologies, a vision component is used to photograph the screw, and the size of the screw is measured based on the captured image and compared with a preset size to determine whether the screw is qualified. However, when the position of the camera remains unchanged, only a projected image of the screw in one direction can be captured. Thus, only the planar dimensions of the screw can be measured, and the screw size cannot be accurately measured.

[0037] Embodiments of this application provide a detection device, including a receiving chamber, a transmitting structure, and a vision component. The receiving chamber is provided with an insertion interface configured to allow a workpiece to enter and exit the interior of the receiving chamber; a reflective structure is disposed inside the receiving chamber; the reflective structure is configured to emit imaging light to the side of the workpiece when powered on; the vision component includes an imaging element and a detection module, the imaging element being disposed at one end of the receiving chamber; when the reflective structure is de-energized, the imaging element can capture a projected image of the workpiece along a first direction to form a first image; when the reflective structure is powered on, the imaging element can receive imaging light reflected from the side of the workpiece to form a second image; the detection module is electrically connected to the imaging element to measure the size of the workpiece.

[0038] In the aforementioned detection device, when the reflective structure is not energized, it does not operate, and the imaging component operates to capture a projected image of the workpiece along a first direction, forming a first image. When the reflective structure is energized, it reflects imaging light to the side of the workpiece, and the imaging component receives the reflected imaging light from the side of the workpiece, forming a second image. The detection module measures the dimensions of the workpiece in other directions perpendicular to the first direction using the first image, and measures the dimensions of the workpiece in the first direction using the second image. Compared to the imaging component only capturing a projected image of the workpiece in one direction to measure its dimensions, the reflective structure allows the imaging component to capture images of different positions on the workpiece and form different images, enabling the detection module to measure the dimensions of the workpiece based on different images, thus obtaining more accurate workpiece dimensions.

[0039] The embodiments of this application will be further described below with reference to the accompanying drawings. Unless otherwise specified, the various embodiments in this application can be combined with each other.

[0040] Please see Figure 1 and Figure 2 Let the first direction, the second direction, and the third direction be defined as perpendicular to each other. The first direction is the direction parallel to the direction indicated by Z in the diagram, the second direction is the direction parallel to the direction indicated by Y in the diagram, and the third direction is the direction parallel to the direction indicated by X in the diagram.

[0041] For ease of reference to the diagrams, the first direction will be referred to as "first direction Z" in the following text, the second direction as "second direction Y" and the third direction as "third direction X".

[0042] One embodiment of this application provides an automated device (not shown), including a detection device 100. The detection device 100 is used to detect whether a workpiece 200 is qualified. When the detection device 100 detects that the workpiece 200 is qualified, the automated device is used to install the qualified workpiece 200 onto the product.

[0043] Before the workpiece 200 is installed onto the product, the workpiece 200 is inspected by the inspection device 100 to control the size of the workpiece 200, so as to prevent the workpiece 200 from being unqualified, which would reduce the product quality or damage the product, and thus improve the product yield and quality.

[0044] In some embodiments, the workpiece 200 includes screws, bolts, or studs, and this application does not limit this.

[0045] In some embodiments, the automated equipment further includes a bracket 10, on which the detection device 100 is mounted.

[0046] In some embodiments, the support 10 includes a worktable 11, a first support portion 12, a second support portion 13, and a third support portion 14. The first support portion 12, the second support portion 13, and the third support portion 14 are all fixedly connected to the worktable 11.

[0047] Please see Figure 2 In some embodiments, the detection device 100 includes a receiving chamber 20 and a reflective structure 30 (see Figure 100). Figure 4 The receiving chamber 20 is fixed to the first support 12, the vision component 40 is fixed to the second support 13, and the reflective structure 30 is disposed inside the receiving chamber 20.

[0048] Please combine Figure 3 and Figure 4 The receiving chamber 20 is provided with an insertion interface 22, which is used for the workpiece 200 to enter and exit the interior of the receiving chamber 20 along the first direction Z, so that the insertion interface 22 can position the insertion position of the workpiece 200 into the receiving chamber 20.

[0049] Please see Figure 1 and Figure 2 The vision component 40 includes an imaging element 41, which is fixed to the second support portion 13. The imaging element 41 is located at the end of the receiving chamber 20 away from the insertion interface 22, so as to capture an orthographic projection image of the workpiece 200 along the first direction Z when the reflective structure 30 is not working, and form a first image. When the reflective structure 30 is not working, the reflective structure 30 is transparent, and the transparent reflective structure 30 does not affect the imaging by the imaging element 41.

[0050] Please see Figures 4 to 6 The reflective structure 30 is installed inside the receiving chamber 20. After the workpiece 200 is inserted into the receiving chamber 20, the reflective structure 30 is located on one side of the workpiece 200.

[0051] When the reflective structure 30 is energized, it emits imaging light to the side of the workpiece 200. The side of the workpiece 200 reflects the imaging light to the imaging element 41. The imaging element 41 receives the imaging light reflected from the side of the workpiece 200 and forms a second image.

[0052] The vision component 40 also includes a detection module (not shown), which is electrically connected to the imaging component 41.

[0053] When the reflective structure 30 is not working, the detection module can measure the dimensions of the workpiece 200 in the first image, specifically the dimensions of the workpiece 200 in the second direction Y and the third direction X. In the illustrated embodiment, the imaging element 41 captures the bottom surface of the workpiece 200 from bottom to top to measure the length and width of the workpiece 200. The length of the workpiece 200 refers to its dimension in the third direction X, and the width of the workpiece 200 refers to its dimension in the second direction Y. When the workpiece 200 is a screw, the length and width of the workpiece 200 are equal to its diameter.

[0054] When the reflective structure 30 is energized, it operates, and the detection module can measure the dimensions of the workpiece 200 in the second image. In the illustrated embodiment, the imaging element 41 captures the side view of the workpiece 200 to measure its height or diameter. The height of the workpiece 200 refers to its dimension in the first direction Z.

[0055] Therefore, with the positions and angles of the imaging element 41 and the workpiece 200 remaining constant, the reflective structure 30 enables the imaging element 41 to capture images of the workpiece 200 from at least two different positions, forming different images. The detection module can then measure the dimensions of the workpiece 200 based on these different images. Compared to capturing only one face or one position of the workpiece 200, capturing images from at least two positions allows for the measurement of the workpiece 200's dimensions in at least two directions. During the measurement of the workpiece 200's dimensions, the positions and angles of the imaging element 41 and the workpiece 200 remain constant, saving time spent adjusting the positions of either the imaging element 41 or the workpiece 200 and improving the measurement efficiency of the workpiece 200.

[0056] In some embodiments, the detection module can also compare the measured size of the workpiece 200 with the preset size in the system. When the measured size of the workpiece 200 is greater than or less than the preset size, the workpiece 200 is determined to be unqualified.

[0057] In some embodiments, when the workpiece 200 is inserted into the interior of the receiving chamber 20 from the insertion interface 22, the imaging element 41 is directly facing the center of the workpiece 200 in the first direction Z.

[0058] Please see Figure 1 and Figure 2 In some embodiments, when the camera 41 photographs the workpiece 200, the detection device 100 provides supplementary light, which can be natural light or light emitted by an external light source 50.

[0059] In some embodiments, the detection device 100 further includes a light source 50, which is fixed to the third support portion 14. The light source 50 is disposed between the receiving chamber 20 and the imaging element 41. The light source 50 is configured to provide supplementary light to the workpiece 200 along the extending direction of the receiving chamber 20 to supplement the illumination of the imaging element 41, so that the imaging element 41 can clearly photograph the workpiece 200.

[0060] Please see Figure 3 and Figure 4 In some embodiments, the interior of the housing 20 is provided with a supplementary light source 51 (see reference). Figure 4 Along the first direction Z, the supplementary light source 51 is located on the side of the reflective structure 30 facing away from the light source 50. The supplementary light source 51 corresponds to the light source 50 and is used to provide supplementary light to the workpiece 200, so as to further supplement the light for the imaging device 41, enabling the imaging device 41 to clearly photograph the workpiece 200.

[0061] In some embodiments, both the light source 50 and the supplementary light source 51 are annular.

[0062] Please see Figure 4 and Figure 5 In some embodiments, the reflective structure 30 includes a first light-emitting element 31, which is disposed on one side of the insertion interface 22 along the second direction Y. The first light-emitting element 31 has a first inclined surface 311, which forms a first angle α with the first direction Z. The first angle α is 45° (see reference). Figure 5 ).

[0063] When the reflective structure 30 (first light-emitting element 31) is working, the first light-emitting element 31 can emit imaging light (first imaging light) in a direction perpendicular to the first inclined surface 311 to the side surface (first side surface) of the workpiece 200, so that the second image is the orthographic projection image of the workpiece 200 along the second direction Y, thereby enabling the detection module to measure the dimensions of the workpiece 200 in the second image in the first direction Z and the third direction X.

[0064] The reflective structure 30 can switch between an on-state and an off-state. The vision component 40 can form images of the workpiece 200 in two mutually perpendicular directions and measure the dimensions of the workpiece 200. The width of the workpiece 200 can be measured in both the first and second images formed by the vision component 40. By measuring the width of the workpiece 200 twice, the width value of the workpiece 200 can be obtained more accurately.

[0065] Please see Figure 4 and Figure 5 In some embodiments, the reflective structure 30 further includes a second light-emitting element 32. The second light-emitting element 32 and the first light-emitting element 31 are spaced apart and distributed around the insertion interface 22. The second light-emitting element 32 and the first light-emitting element 31 operate alternately. That is, when the first light-emitting element 31 is working, the second light-emitting element 32 is not working.

[0066] When the first light-emitting element 31 is working, it emits a first imaging light to a first side of the workpiece 200, and the imaging element 41 receives the first imaging light reflected from the first side. When the second light-emitting element 32 is working, it emits a second imaging light to a second side of the workpiece 200, and the imaging element 41 receives the second imaging light reflected from the second side, thereby enabling the imaging element 41 to form different second images one by one.

[0067] Imaging light rays at different angles are emitted to different sides of the workpiece 200 by the first light-emitting element 31 and the second light-emitting element 32, so that the imaging element 41 can capture images of different sides of the workpiece 200 to measure the size of the workpiece 200 from different angles.

[0068] Please see Figure 4 and Figure 6 In some embodiments, the second light-emitting element 32 is disposed on one side of the insertion interface 22 along the third direction X. The second light-emitting element 32 has a second inclined surface 321, which forms a second angle β with the first direction Z. The second angle β is 45° (see reference). Figure 6 ).

[0069] When the second light-emitting element 32 is working, the second light-emitting element 32 can emit a second imaging light in a direction perpendicular to the second inclined plane 321, so that the second image is a positive projection image of the workpiece 200 along the third direction X, thereby enabling the detection module to measure the size of the workpiece 200 in the second image in the first direction Z and the second direction Y.

[0070] Therefore, the reflective structure 30 has three states: the first light-emitting element 31 is in operation, the second light-emitting element 32 is in operation, and the power-off state (the reflective structure 30 is not in operation). In these three states, the detection device 100 enables the vision component 40 to form images of the workpiece 200 in three mutually perpendicular directions and measures the dimensions of the workpiece 200, thereby determining the length, width, and height of the workpiece 200. Furthermore, since the length, width, and height of the workpiece 200 are measured from both sides, the measured dimensions of the workpiece 200 are more accurate. During the measurement of the workpiece 200, the positions of the imaging element 41 and the workpiece 200 remain unchanged, saving time spent adjusting the positions of the imaging element 41 and the workpiece 200 and improving measurement efficiency.

[0071] In some embodiments, both the first light-emitting element 31 and the second light-emitting element 32 are prisms. Both the first imaging ray and the second imaging ray are white light.

[0072] In some embodiments, the interior of the receiving chamber 20 is provided with a mounting groove 21, and the first light-emitting element 31 and the second light-emitting element 32 are both fixed to the inner wall of the mounting groove 21. The bottom of the mounting groove 21 has an opening 211, and the light source 50 provides supplementary light to the workpiece 200 through the opening 211. The side of the workpiece 200 reflects imaging light to the imaging element 41 through the opening 211.

[0073] In some embodiments, the imaging element 41 is a charge-coupled device (CCD).

[0074] Please see Figure 1 In some embodiments, the automated equipment also includes a material handling unit (not shown). The detection device 100 also includes a loading unit 60 mounted on the worktable 11. The loading unit 60 has an inlet 61 and a loading port 62. The inlet 61 is configured to receive workpiece 200, the loading unit 60 is configured to convey workpiece 200 to the loading port 62, and the loading port 62 is configured to provide workpiece 200 to the loading unit.

[0075] Workpiece 200 can be fed from the feed port 61 to the feeder 60, and then fed to the take-up device through the take-up port 62 of the feeder 60. It has a high degree of automation and can improve the feeding efficiency of workpiece 200.

[0076] In some embodiments, the feeding component is an electric screwdriver. By feeding the electric screwdriver through the feeding component 60, the workpiece 200 can be secured to the product after it has passed inspection.

[0077] In some embodiments, the feeding component 60 is a screw feeder, i.e., a screw feeder or feeder. The screw feeder can automatically, continuously, and accurately deliver screws to the feeding port 62, thereby replacing the manual actions of picking up and placing screws.

[0078] In some embodiments, the detection device 100 further includes a baffle 70 mounted on the worktable 11. The baffle 70 is rotatable relative to the loading part 60 to cover the feed inlet 61. The baffle 70 is configured to rotate and open the feed inlet 61 when the workpiece 200 is matched. Workpiece 200 matching means that the model of the workpiece 200 is the same as the model set by the system.

[0079] When the workpiece 200 is of the correct type, the baffle 70 is rotated to open and the workpiece 200 is fed through the feed port 61; when the workpiece 200 is of the wrong type, the baffle 70 is rotated to cover the feed port 61 to prevent the wrong workpiece 200 from being fed.

[0080] In some embodiments, the baffle 70 can be manually driven to open or close by the feeder. By setting the baffle 70, the action of driving the baffle 70 to open and close is added to remind the feeder to check whether the workpiece 200 model is correct.

[0081] In some embodiments, the automated equipment further includes an identification element. The detection device 100 also includes a drive assembly 71 connected to a baffle 70 and electrically connected to the identification element to drive the baffle 70 to rotate when the identification element identifies a match between the workpiece 200 and the baffle.

[0082] The identification device identifies workpiece 200 to verify its matching, preventing the feeder from skipping the verification step and feeding the workpiece directly. When workpiece 200 matches, the rotating assembly drives the baffle 70 to rotate, thereby improving the level of automation and reducing the labor intensity of the feeder.

[0083] In some embodiments, the identification device includes a barcode scanner, which scans the barcode of the workpiece 200 to determine whether the workpiece 200 matches.

[0084] In some embodiments, the drive component 71 is an electromagnetic lock.

[0085] In some embodiments, the detection device 100 further includes a demagnetizing element 80, which is mounted on the worktable 11. The demagnetizing element 80 has a demagnetizing inlet 81, which allows the workpiece 200 to be inserted, and the demagnetizing element 80 is configured to demagnetize the workpiece 200.

[0086] The residual magnetism on the workpiece 200 is eliminated by the demagnetizing component 80, which can prevent magnetic interference with the installation of the workpiece 200; after the demagnetized workpiece 200 is installed on the product, the interference of magnetism on the product can be reduced.

[0087] In some embodiments, the demagnetizing element 80 is a demagnetizer.

[0088] In some embodiments, the detection device 100 further includes a collection tank 90, which is disposed on the support 10 and is used to load the workpiece 200.

[0089] When workpiece 200 cannot be demagnetized or its dimensions are not up to standard, the pick-up device can throw workpiece 200 into collection tank 90. ​​Collection tank 90 collects discarded workpieces 200, facilitating unified processing of discarded workpieces 200, such as discarding them or calculating the defect rate of workpieces 200.
