Description

Technical Field

[0001] This application relates to the field of detection technology, and in particular to a detection device. Background Technology

[0002] Inspection devices are widely used in industries such as machinery, electronics, instrumentation, and plastics, and are one of the effective methods for measuring and obtaining dimensional data. To achieve a high degree of automation, inspection devices are generally equipped with data acquisition devices, which utilize vision technology to identify the workpiece to be measured.

[0003] However, in practical applications, since the measuring device may have multiple types of measurands, it may be unable to accurately identify the measurands when they are different, resulting in low measurement accuracy of the measuring device. Utility Model Content

[0004] This application provides a detection device that can facilitate the identification of different measurands and improve the measurement accuracy of the measurand.

[0005] This application provides a testing apparatus, including a measuring device and a data acquisition device. The measuring device includes a worktable with multiple placement areas for holding a workpiece to be measured. The data acquisition device is communicatively connected to the measuring device and is positioned opposite the worktable, for acquiring images of the workpiece on the worktable. The data acquisition device can send the images to the measuring device, enabling the measuring device to identify parameter information of the workpiece based on the images and to measure the workpiece according to the parameter information.

[0006] At least some of the placement areas are different colors, and the different colored placement areas are used to hold the measuring parts of different colors.

[0007] In the testing device proposed in this application, the measuring equipment can complete tasks such as positioning the workpiece to be measured with the cooperation of the data acquisition equipment, thereby realizing the measurement of the workpiece to be measured.

[0008] Furthermore, since the workbench includes placement areas of different colors, different parts can be placed in the appropriate area according to their color, thereby improving the accuracy of the measuring equipment in identifying the parts and thus making the measuring device more accurate in measuring the parts.

[0009] Optionally, the detection device also includes a base, and the acquisition equipment includes a camera and a mounting component. The mounting component is connected to the base, and the camera is connected to the mounting component. The camera is used to acquire images of the object to be measured in the placement area.

[0010] The detection device also includes a base, through which the acquisition equipment can be installed. The base provides reliable and stable support for the acquisition equipment, ensuring the reliability of the acquisition equipment when acquiring images.

[0011] Optionally, the mounting components include an extension arm and a base, the base being connected to a base, the extension arm being connected to the base and movable relative to the base, and the camera being connected to the extension arm, which can move the camera.

[0012] Thus, for different parts to be measured, the extension arm can be operated according to the size and height of the part to be measured, and the distance between the camera and the worktable, and / or the relative relationship between the camera and the part to be measured, etc., so that the image acquired by the camera when acquiring the image of the part to be measured is more accurate.

[0013] Optionally, the camera can be a 2D camera or a 3D camera.

[0014] In this way, different types of cameras can be used to acquire images of the object to be measured.

[0015] Optionally, the acquisition device also includes a mounting plate, which is fixed to the mounting component and has mounting holes, with the camera positioned in the mounting holes.

[0016] With the above setup, the camera can be mounted on the mounting plate. The mounting plate provides a mounting location for the mounting plate, which in turn supports the camera, giving it a defined position.

[0017] Optionally, the mounting piece is also equipped with multiple light sources arranged around the camera. These light sources are used to supplement the camera's illumination when the camera acquires images of the object to be measured in the placement area.

[0018] Thus, multiple light sources are arranged around the camera. These light sources can follow the camera to illuminate different areas of the worktable, ensuring consistent illumination across the worktable. Consequently, during the operation of the detection device, the acquisition equipment's identification of the workpiece at different locations on the worktable is also relatively consistent.

[0019] Optionally, the worktable includes a base plate with different placement areas and support columns on the base plate for supporting the workpiece to be measured.

[0020] In this way, the support column can reduce the possibility of the measuring device sliding on the base plate, which could lead to insufficient measurement accuracy of the measuring device.

[0021] Optionally, the base plate is provided with threaded holes, and the side of the bearing column facing the base plate is provided with mounting holes, and fasteners are provided between the mounting holes and the threaded holes.

[0022] With the above configuration, the support column and the base plate can be connected by a threaded connection. This makes the connection between the support column and the base plate detachable. Therefore, a suitable support column can be selected to support the workpiece depending on the specific workpiece being measured.

[0023] Optionally, a sliding groove is provided on the base plate, and an installation block is provided on the side of the support column facing the base plate. The installation block is embedded in the sliding groove and can slide in the sliding groove.

[0024] In this way, the support column can slide on the base plate. When the workpiece to be measured is placed on the worktable, the position of the support column can be adjusted according to the shape of the workpiece so that the support column can support the workpiece.

[0025] Optionally, the base plate includes multiple interconnected sub-plates, at least some of which are different colors, and the surfaces of the sub-plates with load-bearing columns form a placement area.

[0026] With the above settings, multiple sub-boards can form base plates of different colors and / or with different distribution patterns of placement areas, which can facilitate the base plate to support different parts to be measured. Attached Figure Description

[0042] Reference Figures 1 to 3 As shown, the detection device 100 proposed in this application embodiment includes a measuring device 10 and a data acquisition device 20. The measuring device 10 includes a worktable 11 with multiple placement areas 116 for holding a workpiece 300 to be measured. The data acquisition device 20 is communicatively connected to the measuring device 10 and is opposite to the placement areas 116, for acquiring images of the workpiece 300 on the placement areas 116. The data acquisition device 20 can send the images to the measuring device 10, so that the measuring device 10 can identify the parameter information of the workpiece 300 based on the images and measure the workpiece 300 based on the parameter information.

[0043] At least some of the placement areas 116 are different colors, and the different colored placement areas 116 are used to hold the measuring pieces 300 of different colors.

[0044] In this embodiment of the application, the detection device 100 can measure the workpiece 300 to be measured by the measuring device 10 to extract the geometric features and dimensional information of the workpiece 300 for analysis and processing by the staff.

[0045] In this application, the measuring device 10 has a worktable 11. When measuring the workpiece 300, the workpiece 300 can be placed on the worktable 11 and supported by the worktable 11. Then, other components of the measuring device 10 can measure the workpiece 300.

[0046] The detection device 100 also includes a data acquisition device 20, which can cooperate with the measuring device 10 to enable the measuring device 10 to perform automated measurement of the workpiece 300.

[0047] Specifically, when the workbench 11 carries the workpiece 300 to be measured, the acquisition device 20 can acquire an image of the workpiece 300 on the workbench 11. In this way, the acquired image contains parameter information such as the position and type of the workpiece 300.

[0048] Since the acquisition device 20 is communicatively connected to the measuring device 10, the acquisition device 20 can send images to the measuring device 10. After receiving the images, the measuring device 10 can identify the parameter information of the workpiece 300 to be measured based on the images, so that the measuring device 10 can measure the workpiece 300 based on the parameter information.

[0049] In this way, the acquisition device 20 can capture the part to be measured 300, obtain an image containing parameter information, and transmit the image to the measuring device 10. Then, the measuring device 10 can obtain parameter information such as the position and type of the part to be measured 300 based on the image, so that the measuring device 10 can measure the part to be measured 300 according to the parameter information.

[0050] When using the detection device 100 for measurement, there are generally multiple types of the measured component 300, and these multiple measured components 300 may have different colors. In order to ensure that the acquisition device 20 can acquire images of the measured components 300 of different colors better, and to facilitate the measurement device 10 in recognizing the parameter information of the measured component 300, the worktable 11 has multiple placement areas 116, at least some of which are different colors. The placement areas 116 of different colors are used to hold the measured components 300 of different colors.

[0051] Thus, the worktable 11 can support the workpiece 300 to be measured through different placement areas 116. Since at least some of the placement areas 116 are of different colors, a suitable placement area 116 can be selected based on the color of the workpiece 300 when placing it. Therefore, the contrast between different colors can be used to improve the image acquisition accuracy of the acquisition device 20 of the workpiece 300.

[0052] Specifically, the contrast between the placement area 116 and the color of the measurement object 300 carried on the placement area 116 can be high. Therefore, the difference between the measurement object 300 and its placement area 116 can be more significant, which makes it easier for the acquisition device 20 to acquire an image of the measurement object 300, and allows the measurement device 10 to identify the shape and outline of the measurement object 300 based on the image.

[0053] To accommodate multiple measurement objects 300 of various colors in the multiple placement areas 116, the colors of the multiple placement areas 116 can include white and black. Thus, light-colored measurement objects 300 with higher brightness (such as white, beige, and yellow) can be placed on the black placement area 116. Dark-colored measurement objects 300 with lower brightness (such as black, brown, and blue) can be placed on the white placement area 116.

[0054] In the above example, the color contrast between the measured component 300 and the placement area 116 supporting it is high. Thus, in the image of the measured component 300 acquired by the acquisition device 20, the change in pixel values ​​between the edge of the measured component 300 and the placement area 116 is more pronounced, which can improve the accuracy of the measurement device 10 in identifying the measured component 300, thereby resulting in higher measurement accuracy of the detection device 100 for the measured component 300.

[0055] Of course, besides the examples above, the placement area 116 can also be other colors. For example, yellow, blue, etc. This application embodiment does not specifically limit the specific color of the placement area 116, as long as the color of the placement area 116 is different from the color of the measurement piece 300 carried on it.

[0056] In summary, in the embodiments of this application, the measuring device 10 can cooperate with the data acquisition device 20 so that the measuring device 10 can obtain the parameter information of the workpiece 300 to be measured, so that the measuring device 10 can conveniently measure the workpiece 300.

[0057] Furthermore, since the workbench 11 includes placement areas 116 of different colors, different workpieces 300 can be placed in the appropriate placement area 116 according to their colors, thereby improving the accuracy of the measuring device 10 in identifying the workpieces 300 and thus making the measuring device 100 more accurate in measuring the workpieces 300.

[0058] Furthermore, through the above-described scheme, in the detection device 100 proposed in this application, the measuring device 10 can complete tasks such as positioning the workpiece 300 to be measured with the cooperation of the acquisition device 20, thereby realizing the measurement of the workpiece 300. This can reduce the waste of human resources during the measurement process and improve the detection efficiency of the workpiece 300.

[0059] The detection device 100 may include a controller, which can be communicatively connected to the measuring device 10 and can control the measuring device 10 to measure the workpiece 300.

[0060] In this application, the measuring device 10 may include a measuring mechanism and a controller. The controller may be embedded in the measuring mechanism. In this case, the data acquisition device 20 may be communicatively connected to the controller in the measuring mechanism.

[0061] Alternatively, the measuring device 10 may also include a central control device, and the controller can be located within the central control device. In this case, both the data acquisition device 20 and the measuring mechanism can be communicatively connected to the central control device. That is, the data acquisition device 20 can communicate with the measuring mechanism through the central control device.

[0062] In this way, the measuring device 10 can receive the image sent by the acquisition device 20 through the controller, and identify the parameter information of the measured part 300 based on the image.

[0063] In this process, after the measuring device 10 identifies the type of the part to be measured 300 based on the image, the controller can retrieve the measurement program for that type of part according to the type of the part to be measured 300, and control the measuring mechanism to measure the part to be measured 300.

[0064] In summary, in the testing device 100 proposed in this application, if there is a workpiece 300 to be measured on the worktable 11, the acquisition device 20 can acquire an image of the workpiece 300, so that the measuring device 10 can automatically position and measure the workpiece 300 based on the image. In this way, the involvement of personnel can be reduced and the automation level of the testing device 100 can be improved.

[0065] It should be noted that the parameter information may include any part of the parameters such as the shape, position, size, model and specifications of the part to be measured 300.

[0066] In this application, the measuring device 10 can specifically be a coordinate measuring machine, a video measuring instrument, or other similar equipment. This application does not specifically limit the specific type of device used.

[0067] It should also be noted that there are multiple ways to set up the placement areas 116 on the workbench 11. For example, there can be 6 different placement areas 116 on the workbench 11, and the 6 placement areas 116 can be set up in 2 rows and 3 columns or 3 rows and 2 columns.

[0068] In the six placement areas 116, any two adjacent placement areas 116 can have different colors. Alternatively, placement areas 116 in the same row can have the same color, while placement areas 116 in different rows can have different colors, and so on. This application embodiment does not specifically limit the specific method for setting the colors of multiple placement areas 116.

[0069] Of course, the number of placement areas 116 on the base plate 111 can also be 2, 3, 4 or 8, etc. The specific number of placement areas 116 is not specifically limited in this embodiment.

[0070] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the detection device 100 may further include a base 101, and the acquisition device 20 includes a camera 21 and a mounting component 22. The mounting component 22 is connected to the base 101, and the camera 21 is connected to the mounting component 22. The camera 21 is used to acquire images of the object to be measured 300 on the placement area 116.

[0071] The detection device 100 also includes a base 101, through which the acquisition device 20 can be installed. The base 101 can provide reliable and stable support for the acquisition device 20, ensuring the reliability of the acquisition device 20 when acquiring images.

[0072] In this embodiment, the mounting component 22 can be connected to the base 101, and the camera 21 is mounted via the mounting component 22. The acquisition device 20 can acquire images of the object to be measured 300 via the camera 21, and then transmit the images to the measurement device 10.

[0073] In this application, both the measuring device 10 and the data acquisition device 20 can be mounted on the base 101, which can provide support for the measuring device 10 and the data acquisition device 20.

[0074] In some embodiments, such as Figure 1 and Figure 4As shown, the mounting component 22 may include an extension arm 221 and a base 222. The base 222 is connected to the base 101, the extension arm 221 is connected to the base 222 and can move relative to the base 222, and the camera 21 is connected to the extension arm 221, which can drive the camera 21 to move.

[0075] With the above configuration, the camera 21 is mounted on the extension arm 221. Since the extension arm 221 can move relative to the base 222, when the extension arm 221 moves, it can also move the camera 21, thus changing the relative position between the camera 21 and the worktable 11.

[0076] Thus, for different parts to be measured 300, the extension arm 221 can be operated according to the size, height, etc. of the parts to be measured 300 to adjust the distance between the camera 21 and the worktable 11, and / or the relative relationship between the camera 21 and the parts to be measured 300, so that the images acquired by the camera 21 when acquiring images of the parts to be measured 300 are more accurate.

[0077] In this embodiment, the extension arm 221 can be a robotic arm or it can be composed of multiple sleeved cylindrical rods. The multiple cylindrical rods can slide relative to each other to make the extension arm 221 extendable and retractable, which can also realize the adjustment of the position of the camera 21, etc.

[0078] In addition to mounting the camera 21 via the extension arm 221 as described above, the camera 21 can also be mounted in other ways. For example, a drive motor can be connected to the base 222, and the camera 21 can be connected to the drive motor so that the drive motor can move the camera 21.

[0079] Of course, camera 21 can also be directly fixed to base 222. In this way, camera 21 can also acquire images of the workpiece 300 to be measured on worktable 11.

[0080] It should be noted that, in this embodiment, the connection between the extendable arm 221 and the base 222 can be achieved using screws, bolts, or pins. The connection between the camera 21 and the extendable arm 221 can also be achieved using screws, pins, or snap-fit ​​connections, etc.

[0081] In some embodiments, camera 21 may be a two-dimensional camera or a three-dimensional camera.

[0082] In this application, the camera 21 can be of different types, all of which can realize the function of acquiring images of the workpiece 300 to be measured on the worktable 11. Specifically, the camera 21 can be a two-dimensional camera or a three-dimensional camera, both of which can acquire images of the workpiece 300 to be measured.

[0083] In this application, camera 21 is used to facilitate the measuring device 10 in identifying the position, shape, size, etc. of the object to be measured 300. Preferably, camera 21 can be a two-dimensional camera. This allows for higher accuracy in the images acquired by camera 21.

[0084] The specific dimensions of the part to be measured 300 in three dimensions can be obtained by measuring the measuring device 10.

[0085] In some embodiments, such as Figure 4 As shown, the acquisition device 20 may also include a mounting plate 23, which is fixed to the mounting component 22. The mounting plate 23 has mounting holes, and the camera 21 is mounted in the mounting holes.

[0086] With the above configuration, the camera 21 can be mounted on the mounting member 22 via the mounting plate 23. The mounting member 22 provides a mounting position for the mounting plate 23, which in turn supports the camera 21, thus giving the camera 21 a defined position.

[0087] The camera 21 includes a camera lens, which is the core component of the camera 21 and is responsible for acquiring and recording images. In order to reduce the impact of the mounting plate 23 on the camera 21's image acquisition, the camera 21 can be installed by passing the camera lens through the mounting hole, or by having the camera lens extend from the side of the mounting plate 23 toward the worktable 11 through the mounting hole.

[0088] This makes it easier for the camera to capture images of the workpiece 300 to be measured on the worktable 11.

[0089] When the mounting component 22 includes an extension arm 221 and a base 222, the mounting plate 23 can be connected to the end of the extension arm 221 that is away from the base 222. When the extension arm 221 moves relative to the base 222, the extension arm 221 can drive the mounting plate 23 to move, thereby allowing the camera 21 on the mounting plate 23 to also move.

[0090] The mounting plate 23 can be fixed to the extension arm 221 by means of screwing, bonding or welding.

[0091] In some embodiments, the mounting component 22 may also be provided with multiple light sources, which are arranged around the camera 21. The light sources are used to provide supplemental lighting for the camera 21 when the camera 21 acquires images of the object to be measured 300 on the placement area 116.

[0092] In this embodiment, multiple light sources are arranged around the periphery of the camera 21. These multiple light sources can illuminate different areas of the worktable 11 from different angles, ensuring consistent illumination across the worktable 11. Consequently, during the operation of the detection device 100, the acquisition device 20's identification of the measured object 300 at different locations is also more consistent. This reduces the possibility that some measured objects 300 are clear while others are blurry in the images acquired by the acquisition device 20.

[0093] Furthermore, the surrounding arrangement of multiple light sources can create a device similar to a shadowless lamp. This reduces the possibility of shadows forming on the worktable 11 due to the installation of the mounting components 22, resulting in higher brightness throughout the worktable 11. This allows for clearer images of the workpiece 300 captured by the camera 21, facilitating subsequent image recognition of parameter information by the measuring equipment 10, thus ensuring more accurate parameter information.

[0094] It should be noted that when a mounting plate 23 is provided on the mounting component 22, multiple light sources can be specifically set on the mounting plate 23 and arranged around the mounting holes.

[0095] It should also be noted that the multiple light sources can be colored light sources, such as yellow, blue, red, etc., so that the edges of the measured part 300 are clearer under the illumination of multiple light sources.

[0096] Among the multiple light sources, all light sources may have the same color or different colors. This application does not specifically limit this.

[0097] Of course, multiple light sources can also be white light sources, which have good color reproduction of the measured part 300.

[0098] In some embodiments, such as Figure 1 and Figure 2 As shown, the worktable 11 may include a base plate 111, which has different placement areas 116. A support column 112 is provided on the base plate 111 to support the workpiece 300 to be measured. With the above arrangement, the measuring device 10 can specifically support the workpiece 300 to be measured via the support column 112 on the base plate 111 and limit the movement of the workpiece 300.

[0099] A support column 112 is provided on the base plate 111. In addition to supporting the workpiece 300 to be measured, the support column 112 also has a limiting function for the workpiece 300. In this way, under the action of the support column 112, the possibility of the workpiece 300 sliding on the base plate 111, which could lead to insufficient measurement accuracy of the measuring device for the workpiece 300, can be reduced.

[0100] The placement area 116 can be specifically set on the base plate 111 to support different measuring pieces 300.

[0101] It should be noted that the workbench 11 may also include a main body, and the base plate 111 can be detachably connected to the main body. In this way, if the base plate 111 is damaged after prolonged use, it can be easily removed and replaced.

[0102] In this embodiment, the support column 112 can be arranged on the base plate 111 in different ways so that the support column 112 can support the sample 300 to be measured. Here, the following two methods are specifically described as examples.

[0103] Method 1, see reference Figure 2 and Figure 3 The base plate 111 is provided with a threaded hole 113, and the support column 112 is provided with a mounting hole on the side facing the base plate 111. Fasteners are provided between the mounting hole and the threaded hole 113.

[0104] With the above configuration, the support column 112 and the base plate 111 can be connected by a threaded connection. Thus, the connection between the support column 112 and the base plate 111 is detachable. Therefore, a suitable support column 112 can be selected to support the part 300 to be measured, depending on the specific part being measured.

[0105] When the workpiece 300 is placed on the worktable 11, it can be placed on a suitable support column 112 on the base plate 111, so that the position of the workpiece 300 on the support column 112 is relatively stable, so that the measuring equipment 10 can measure the workpiece 300 in the future.

[0106] In addition, for some parts to be measured 300, a connecting hole may be provided on the part to be measured 300, and the wall of the connecting hole may be provided with an internal thread. In this case, when the part to be measured 300 is supported by the base plate 111, the support column 112 may not be provided on the base plate 111.

[0107] At this time, the base plate 111 can directly support the part to be measured 300, and make the connecting hole on the part to be measured 300 opposite to the threaded hole 113. Fasteners can be inserted into the connecting hole and the threaded hole 113 so that the part to be measured 300 has a defined position relative to the base plate 111.

[0108] Method 2, such as Figure 2 As shown, a sliding groove 114 is provided on the base plate 111, and an mounting block 115 is provided on the side of the support column 112 facing the base plate 111. The mounting block 115 is embedded in the sliding groove 114 and can slide in the sliding groove 114.

[0109] With the above configuration, the support column 112 and the base plate 111 can be connected by the cooperation of the mounting block 115 and the sliding groove 114. Specifically, the mounting block 115 on the side of the support column 112 facing the base plate 111 can be embedded in the sliding groove 114.

[0110] In this embodiment, since the mounting block 115 can slide in the sliding groove 114, the support column 112 can be operated to slide on the base plate 111. Thus, when the workpiece 300 to be measured is placed on the worktable 11, the position of the support column 112 can be adjusted according to the shape of the workpiece 300, so that the support column 112 can support the workpiece 300.

[0111] That is, in Method 2, the position of the bearing column 112 can be adjusted according to different measuring pieces 300, which can improve the versatility of the base plate 111 in supporting the measuring pieces 300 and improve the ease of use of the testing device 100.

[0112] It should be noted that, in order to improve the load-bearing and limiting functions of the bearing column 112 on the measured part 300, a measured part 300 can be supported and limited by multiple bearing columns 112.

[0113] For example, the part to be measured 300 can be supported by four support columns 112. The side of these four support columns 112 away from the base plate 111 can form a plane, on which the part to be measured 300 can be placed.

[0114] Additionally, a support column 112 can be used to abut against the side of the measuring piece 300 to limit its movement and reduce the possibility of the measuring piece 300 sliding on the plane formed by the aforementioned four support columns 112, thereby affecting the measurement accuracy of the measuring device 10.

[0115] Alternatively, a support column 112 can be set to abut against the top surface of the part to be measured 300 to improve the limiting effect of the part to be measured 300, etc.

[0116] The number of support columns 112 required for a single measuring piece 300 and the specific arrangement of multiple support columns 112 are not specifically limited in this embodiment.

[0117] In some embodiments, the base plate 111 may include a plurality of interconnected sub-plates, at least some of which are different colors, and the surface of the sub-plates on which the support column 112 is provided may form a placement area 116.

[0118] In this way, multiple sub-plates can form different placement areas 116. Furthermore, different sub-plates can be arranged according to the multiple measurement objects 300 to be measured, forming base plates 111 with different colors and / or base plates 111 with different distribution patterns of placement areas 116, which can facilitate the base plate 111 to support different measurement objects 300.

[0119] Multiple sub-plates can be detachably connected via snap-fits, threaded fittings, or other means. This allows for the selection of sub-plates of appropriate colors for assembly based on the type of the part 300 to be measured each time, forming base plates 111 of different colors, thus improving the convenience of measurement by the detection device 100. Furthermore, it facilitates the replacement of sub-plates if they are damaged or faded.

[0120] Alternatively, the base plate 111 can also be a single plate. In this case, multiple placement areas 116 can be divided on the base plate 111. The multiple placement areas 116 can be colored by spraying, electroplating, or coloring, so that at least two of the multiple placement areas 116 have different colors.

[0121] In this embodiment, the measuring device 10 can cooperate with the data acquisition device 20 so that the measuring device 10 can obtain the parameter information of the workpiece 300 to be measured, thereby enabling the measuring device 10 to conveniently measure the workpiece 300. Since the workbench 11 includes placement areas 116 of different colors, for different workpieces 300 to be measured, a suitable placement area 116 can be selected according to the color to improve the accuracy of the measuring device 10 in identifying the workpiece 300, thereby making the measurement accuracy of the detection device 100 of the workpiece 300 higher.

[0122] Finally, it should be noted that the above embodiments are merely specific implementations of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
