In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0048] The embodiments of this application are described below with reference to the accompanying drawings:

[0049] refer to Figures 1 to 4 The inspection fixture according to the embodiments of this application is suitable for side inspection of workpieces such as headphones and speakers. For example, the workpiece to be inspected may be at least a part of the structure of Dolby headphones, Bluetooth speakers, wireless speakers, outdoor speakers, waterproof speakers, and vehicle speakers. The inspection fixture includes a base 100, a drive module 200, and a positioning member 300. The base 100 is used to support the workpiece to be inspected. To ensure that the workpiece to be inspected has a definite position on the base 100 for easy image acquisition and inspection, the base 100 includes a positioning part 110, and the workpiece to be inspected can be positioned and assembled at the location of the positioning part 110. The drive module 200 is connected to the base 100, and the positioning member 300 is connected to the drive module 200. To achieve image acquisition of the side of the workpiece to be inspected, which is assembled at the positioning part 110, a positioning hole 310 is provided along the first positioning member 300 in the first horizontal direction, and the positioning part 110 is located on one side of the positioning member 300. That is, along the first horizontal direction, the opening of the positioning hole 310 faces the positioning part 110, and the positioning member 300 and the positioning part 110 are arranged at intervals. Thus, at least a part of the detection module 500 for image acquisition can be installed in the positioning hole 310, thereby enabling the detection module 500 to be arranged along the first horizontal direction and thus achieving image acquisition of the side of the workpiece to be inspected.

[0050] Furthermore, to adapt to image acquisition of different areas on the side of the workpiece to be inspected, the drive module 200 is configured to drive the positioning member 300 to move along at least one of the second horizontal direction and the vertical direction. That is, the drive module 200 can drive the positioning member 300 to move along the second horizontal direction, or the drive module 200 can drive the positioning member 300 to move along the vertical direction, or the drive module 200 can drive the positioning member 300 to move simultaneously along both the second horizontal direction and the vertical direction. It should be noted that the first horizontal direction and the second horizontal direction are both located in the same horizontal plane, the first horizontal direction is perpendicular to the second horizontal direction, and both the first horizontal direction and the second horizontal direction are perpendicular to the vertical direction. The detection module 500 connected to the positioning component 300 moves synchronously with the positioning component 300. The positioning component 300 is driven by the driving module 200 to move along at least one of the second horizontal direction and the vertical direction, so as to change the projection position of the positioning component 300 in the vertical plane along the first horizontal direction, that is, to change the focusing area of ​​the detection module 500 on the side of the workpiece to be detected, thereby realizing the image acquisition operation of different areas on the side of the workpiece to be detected.

[0051] Specifically, the detection module 500 includes components with image acquisition capabilities, such as a CCD (Charge-coupled Device). The drive module 200 can be a structure such as a ball screw, linear motor, cylinder, or hydraulic cylinder. The positioning component 300 is driven by the drive module 200. The detection module 500 is connected to the positioning component 300, and the detection module 500 and the positioning component 300 move synchronously along at least one of the second horizontal direction and the vertical direction. Thus, without changing the position of the workpiece to be inspected, by adjusting the position of the positioning component 300, the detection module 500 can focus on different areas of the side of the workpiece to be inspected, which is beneficial to improving the efficiency of the inspection operation. Furthermore, since the image acquisition positions differ for different types of workpieces to be inspected, the detection module 500 moves with the positioning component 300 in this application, which facilitates image acquisition operations for different types of workpieces to be inspected, and is beneficial to improving the applicability of the inspection fixture.

[0052] refer to Figures 1 to 4 In another embodiment, the workpiece to be inspected can be a small structure such as headphones or speakers. To ensure the position adjustment accuracy of the inspection fixture, the drive module 200 includes a micrometer. Thus, by rotating the micrometer around an axis, another part of the micrometer can move along a straight line extending from the axis. In turn, the micrometer can drive the positioning component 300 to move, thereby achieving more precise adjustment of the positioning component 300, which is beneficial to improving the accuracy and clarity of image acquisition.

[0053] refer to Figures 1 to 4In other embodiments, to ensure that the workpiece to be tested is more accurately assembled in the positioning part 110, the positioning part 110 includes a plurality of first alignment holes, and the positioning fixture includes a plurality of second alignment holes. The number of first alignment holes and second alignment holes is equal. In the vertical direction, the workpiece to be tested is assembled in the positioning fixture. In the vertical direction, each second alignment hole is projected one-to-one into each first alignment hole. Thus, multiple bolts can be used to position and assemble the positioning fixture in the positioning part 110. As a result, the workpiece has a definite position on the base 100, which facilitates image acquisition and analysis of the vertical side of the workpiece.

[0054] refer to Figures 1 to 4 In some embodiments, the drive module 200 includes a drive frame 210, a horizontal drive assembly 220, and a vertical drive assembly 230. The drive frame 210 is connected to the base 100, and the two are fixed relative to each other. The horizontal drive assembly 220 is connected to the vertical drive assembly 230. One of the horizontal drive assembly 220 and the vertical drive assembly 230 is connected to the drive frame 210, and the other of the horizontal drive assembly 220 and the vertical drive assembly 230 is connected to the positioning member 300. The horizontal drive assembly 220 is used to drive the positioning member 300 to move in a second horizontal direction, and the vertical drive assembly 230 is used to drive the positioning member 300 to move in a vertical direction. Thus, under the joint drive of the horizontal drive assembly 220 and the vertical drive assembly 230, the detection module 500 moves synchronously with the positioning member 300 to realize image acquisition of the side of the workpiece to be detected.

[0055] For example, along the first horizontal direction, the drive frame 210 and the positioning part 110 are spaced apart. The drive frame 210 is connected to the base 100. The horizontal drive assembly 220 is connected to the drive frame 210. The vertical drive assembly 230 is connected to the horizontal drive assembly 220. The positioning member 300 is connected to the vertical drive assembly 230. The horizontal drive assembly 220 is used to drive the vertical drive assembly 230 and the positioning member 300 to move together along the second horizontal direction. The vertical drive assembly 230 is used to drive the positioning member 300 to move along the vertical direction. The second horizontal direction is perpendicular to the vertical direction. Thus, the positioning member 300 drives the detection assembly to move together, thereby changing the projection position of the detection assembly on the side of the workpiece to be detected along the first horizontal direction, thereby enabling image acquisition at different positions on the side of the workpiece to be detected.

[0056] Or, refer to Figures 1 to 4Along the first horizontal direction, the drive frame 210 and the positioning part 110 are spaced apart. The drive frame 210 is connected to the base 100. The vertical drive assembly 230 is connected to the drive frame 210. The horizontal drive assembly 220 is connected to the vertical drive assembly 230. The positioning part 300 is connected to the horizontal drive assembly 220. The vertical drive assembly 230 is used to drive the horizontal drive assembly 220 and the positioning part 300 to move together along the vertical direction. The horizontal drive assembly 220 is used to drive the positioning part 300 to move along the second horizontal direction, which is perpendicular to the vertical direction. Similarly, under the joint action of the vertical drive assembly 230 and the horizontal drive assembly 220, the positioning part 300 drives the detection assembly to move together, so as to change the projection position of the detection assembly on the side of the workpiece to be detected along the first horizontal direction, thereby enabling image acquisition at different positions on the side of the workpiece to be detected.

[0057] refer to Figures 4 to 6 In some embodiments, the horizontal drive assembly 220 includes a horizontal drive member 221, a first horizontal slider 222, and a second horizontal slider 223. The horizontal drive member 221 is connected to the first horizontal slider 222, and the first horizontal slider 222 is connected to the vertical drive assembly 230. The first horizontal slider 222 and the vertical drive assembly 230 can move synchronously. The second horizontal slider 223 is connected to the drive frame 210, and the positioning member 300 is connected to the vertical drive assembly 230. The positioning member 300 and the vertical drive assembly 230 can move synchronously. Thus, the first horizontal slider 222, the vertical drive assembly 230, and the positioning member 300 can move synchronously. Along the second horizontal direction, the first horizontal slider 222 and the second horizontal slider 223 are movably connected. The horizontal drive member 221 can be a micrometer, linear motor, cylinder or hydraulic cylinder or other structure that can achieve linear drive. Driven by the horizontal drive member 221, the first horizontal slider 222 moves relative to the second horizontal slider 223 along the second horizontal direction. Then, the positioning member 300 moves along the second horizontal direction to realize the position adjustment of the detection module along the second horizontal direction.

[0058] For example, the horizontal drive member 221 is a micrometer. By rotating the horizontal drive member 221, a part of the horizontal drive member 221 moves linearly along the second horizontal direction to approach and abut against the drive frame 210 or the second horizontal slider 223. Thus, through the interaction force generated by the horizontal drive member 221 abutting against the drive frame 210, or through the force generated by the horizontal drive member 221 abutting against the second horizontal slider 223, the first horizontal slider 222 can slide relative to the second horizontal slider 223 along the second horizontal direction. In turn, the first horizontal slider 222 drives the vertical drive assembly 230 to move along the second horizontal direction. The vertical drive assembly 230 drives the positioning member 300 to move along the second direction. The detection module assembled on the positioning member 300 can adjust the image sampling position along the second horizontal direction.

[0059] It should be noted that, based on the relative movement of the first horizontal slider 222 and the second horizontal slider 223 along the second horizontal direction, the vertical drive component 230 can also drive the positioning component 300 to move along the vertical direction. Thus, it can not only adjust the movement of the positioning component 300 along the second horizontal direction, but also adjust the position of the positioning component 300 along the vertical direction.

[0060] refer to Figure 7 In other embodiments, to avoid deviation when the first horizontal slider 222 and the second horizontal slider 223 move relative to each other, one of the first horizontal slider 222 and the second horizontal slider 223 is provided with a guide groove and the other is provided with a guide rail. Both the guide rail and the guide groove extend along the second horizontal direction. The guide rail passes into the guide groove and abuts against the groove wall. The two are slidably connected through the guide groove and the guide rail, which is beneficial to improving the accuracy and stability of the relative sliding of the two.

[0061] refer to Figures 4 to 7 In some embodiments, the horizontal drive assembly 220 further includes a first elastic element 224, which is arranged along a second horizontal direction. One end of the first elastic element 224 is connected to a first horizontal slider 222, and the other end is connected to a second horizontal slider 223. Along the second horizontal direction, the first elastic element 224 is configured to pull the first horizontal slider 222. The first elastic element 224 can be a spring. Under the action of the first elastic element 224 along the second horizontal direction, the first horizontal slider 222 tends to move closer to the second horizontal slider 223, thereby ensuring that the horizontal drive member 221 is in contact with the drive frame 210 or the second horizontal slider 223. Furthermore, rotating the horizontal drive member 221 allows the first horizontal slider 222 to move relative to the second horizontal slider 223, which helps to further improve the stability of the movable connection between the first horizontal slider 222 and the second horizontal slider 223, avoids any movement between the first horizontal slider 222 and the second horizontal slider 223 along the second horizontal direction, and ensures the positional accuracy of the positioning member 300.

[0062] It should be noted that in this application, the first elastic member 224 is in a stretched state, which is used to ensure that the horizontal drive member 221 abuts against the second horizontal slider 223, or to ensure that the horizontal drive member 221 abuts against the drive frame 210. Thus, when the horizontal drive member 221 rotates about the axis extending along the second horizontal direction, a part of the horizontal drive member 221 produces a linear movement along the second horizontal direction, and a relative movement occurs between the first horizontal slider 222 and the second horizontal slider 223.

[0063] refer to Figures 4 to 6In some embodiments, the vertical drive assembly 230 includes a vertical drive member 231, a first vertical slider 232, and a second vertical slider 233. The vertical drive member 231 is connected to the first vertical slider 232, and the first vertical slider 232 is connected to the horizontal drive assembly 220. At least a portion of the horizontal drive assembly 220, the vertical drive member 231, and the first vertical slider 232 can move synchronously. The second vertical slider 233 is connected to the positioning member 300, and the second vertical slider 233 and the positioning member 300 can move synchronously. In the vertical direction, the first vertical slider 232 and the second vertical slider 233 are movably connected. In the vertical direction, the vertical drive member 231 abuts against or is connected to the second vertical slider 233. The vertical drive member 231 can be a micrometer, a cylinder, or a hydraulic cylinder, or other structures that can achieve linear drive. Driven by the vertical drive member 231, the second vertical slider 233 moves relative to the first vertical slider 232 in the vertical direction. In turn, the second vertical slider 233 drives the positioning member 300 to move, thereby realizing the position adjustment of the positioning member 300.

[0064] For example, the vertical drive component 231 can be a cylinder or a hydraulic cylinder. The vertical drive component 231 includes a cylinder body and a piston rod. In the vertical direction, the piston rod is slidably connected to the cylinder body. The cylinder body is connected to the first vertical slider 232, and the piston rod is connected to the second vertical slider 233. The piston rod can drive the second vertical slider 233 to move in the vertical direction.

[0065] refer to Figures 4 to 6 In some embodiments, the vertical drive member 231 may include a micrometer. To ensure the vertical movement of the second vertical slider 233, the micrometer is arranged vertically. For example, the second vertical slider 233 includes a groove with a horizontally arranged opening. The micrometer screw of the micrometer extends horizontally into the groove and abuts against the groove wall vertically. Thus, the second vertical slider 233 can move vertically with the micrometer screw of the micrometer, realizing the relative movement of the first vertical slider 232 and the second vertical slider 233 in the vertical direction. Driving the second vertical slider 233 with a micrometer improves the position adjustment accuracy of the second vertical slider 233. Consequently, the positioning member 300 drives the detection module 500 to move, achieving higher positional accuracy and facilitating improved image acquisition accuracy.

[0066] It should be noted that, based on the relative vertical movement of the first vertical slider 232 and the second vertical slider 233, the horizontal drive assembly 220 can also drive the vertical drive component 231, the first vertical slider 232, and the second vertical slider 233 to move along the second horizontal direction. This enables the positioning component 300 to be adjusted in both the vertical and second horizontal directions, making the position adjustment more flexible and improving the applicability of the testing fixture to different types of workpieces to be tested.

[0067] refer toFigures 4 to 6 In some embodiments, the vertical drive member 231 further includes a second elastic member 234. To ensure that the vertical drive member 231 abuts against the second vertical slider 233, the second elastic member 234 is arranged in the vertical direction. In the vertical direction, one end of the second elastic member 234 is connected to the first vertical slider 232, and the other end of the second elastic member 234 is connected to the second vertical slider 233. The second elastic member 234 is configured to pull the second vertical slider 233. The second elastic member 234, in conjunction with the vertical drive member 231, can realize the lifting and lowering of the second vertical slider 233.

[0068] For example, the vertical drive component 231 is a micrometer. When the micrometer rotates around its vertical axis, and the micrometer screw moves downwards, it drives the second vertical slider 233 to descend. The second elastic element 234 is in a stretched state, maintaining the second vertical slider 233 against the vertical drive component 231. When the micrometer screw moves upwards, the second elastic element 234 pulls the second vertical slider 233 upwards, ensuring that the second vertical slider 233 is against the micrometer screw, thus achieving the upward movement of the second vertical slider 233.

[0069] refer to Figures 1 to 8 In other embodiments, the horizontal drive assembly 220 includes a horizontal drive member 221, a first horizontal slider 222, a second horizontal slider 223, and a first elastic member 224. The second horizontal slider 223 is connected to the drive frame 210, and the first horizontal slider 222 is connected to the horizontal drive member 221. The first horizontal slider 222 and the second horizontal slider 223 are movably connected along the second horizontal direction. One end of the first elastic member 224 is connected to the first horizontal slider 222, and the other end of the first elastic member 224 is connected to the second horizontal slider 223. The horizontal drive member 221 can drive the first horizontal slider 222 and the second horizontal slider 223 to move relative to each other along the second horizontal direction.

[0070] In addition, the vertical drive assembly 230 includes a vertical drive member 231, a first vertical slider 232, a second vertical slider 233, and a second elastic member 234. The first vertical slider 232 is connected to the vertical drive member 231 and is also connected to the first horizontal slider 222. The first horizontal slider 222, the first vertical slider 232, and the vertical drive member 231 can move synchronously. The first vertical slider 232 and the second vertical slider 233 are movably connected in the vertical direction. One end of the second elastic member 234 is connected to the first vertical slider 232, and the other end of the second elastic member 234 is connected to the second vertical slider 233. The vertical drive member 231 can drive the first vertical slider 232 and the second vertical slider 233 to move in the vertical direction.

[0071] refer to Figures 1 to 5In some embodiments, to further make the vertical lifting and lowering of the positioning member 300 smoother and more stable, the drive module 200 includes two vertical drive components 230 arranged at intervals along the second horizontal direction. One vertical drive component 230 is connected to one side of the positioning member 300, and the other vertical drive component 230 is connected to the opposite side of the positioning member 300. Thus, the two vertical drive components 230 jointly drive the positioning member 300 to lift and lower in the vertical direction. The opposite sides of the positioning member 300 along the second horizontal direction are more likely to be kept at the same height, effectively avoiding the height difference between the opposite sides of the positioning member 300 along the second horizontal direction, which is beneficial to improving the smoothness and stability of the lifting and lowering of the positioning member 300.

[0072] refer to Figures 1 to 10 In some embodiments, the testing fixture further includes a fixing module 400, which includes a fixing frame 410 and a moving member 420. The fixing frame 410 is connected to the base 100. The moving member 420 is movably connected to the fixing frame 410 in the vertical direction. The fixing module 400 may include a cylinder, and the moving member 420 may be the piston rod of the cylinder. The moving member 420 is configured to move closer to or further away from the positioning part 110 in the vertical direction. The moving member 420 moves closer to the positioning part 110 to hold the workpiece to be tested, so as to further fix the workpiece to be tested, and the testing operation is more accurate and stable.

[0073] refer to Figures 1 to 10 In other embodiments, along the vertical direction, the moving member 420 has multiple abutment posts on the side near the positioning part 110, and a buffer sleeve is provided on the side of the abutment posts near the positioning part 110. The multiple abutment posts can correspond to multiple positions of the workpiece to be inspected, which can both ensure the fixation of the workpiece to be inspected and avoid the vulnerable areas of the workpiece to be inspected. The buffer sleeve can be made of a cushioning material such as silicone or sponge, which can provide cushioning and help protect the workpiece to be inspected.

[0074] refer to Figures 1 to 10 The visual inspection system according to the embodiments of this application includes an inspection module 500 and an inspection fixture in any of the above embodiments. The inspection module 500 is accommodated in the positioning hole 310. The inspection module 500 includes a CCD. The inspection fixture is used to ensure that the inspection module 500 is horizontally assembled, thereby realizing the image acquisition of the side of the workpiece to be inspected without additional adjustment of the assembly of the workpiece to be inspected, which is beneficial to improving inspection efficiency.

[0075] refer to Figures 1 to 10 In some embodiments, the vision inspection system further includes a display module electrically connected to the inspection module 500. The display module is used to receive electrical signals from the inspection module 500 to present the images acquired by the inspection module 500, thereby analyzing whether the workpiece to be inspected is qualified.

[0076] The detection process of the visual inspection system in this application is further described below:

[0077] The workpiece to be inspected is assembled on the positioning part 110 by a positioning fixture. Along the first horizontal direction, the detection module 500 is arranged facing the workpiece to be inspected. The side of the workpiece to be inspected facing the detection module 500 is image acquired and the acquired image is transmitted to the display module. The display module displays a magnified view of a part of the workpiece to be inspected. It is determined whether the position of the magnified structure of the workpiece to be inspected is within the design range. If it is within the design range, the workpiece to be inspected is qualified. If the position of the acquired magnified structure exceeds the design range, the workpiece to be inspected is unqualified.

[0078] It should be noted that the position of the detection module can be adaptively adjusted through the drive module depending on the type of workpiece being detected.

[0079] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
