[0032] The following will further illustrate the technical solutions of the present application with reference to the embodiments and the accompanying drawings.
[0033] Please refer to Figure 1, an embodiment of the present application discloses a detection fixture 100. The detection fixture 100 includes a base 10. The base 10 has an upper surface 10a, and a groove 11 is provided on the upper surface 10a. The groove 11 is used to place the product to be detected. The groove 11 has a bearing bottom surface 11a, a first side wall surface 11b and a second side wall surface 11c connected to the bearing bottom surface 11a. The bearing bottom surface 11a is used to bear the product to be detected. The first side wall surface 11b and the second side wall surface 11c are arranged at an angle. At least one of the first side wall surface 11b and the second side wall surface 11c is configured to contact the product to be detected to position the product to be detected.
[0034] In the detection fixture 100 provided by the present application, by providing the groove 11 on the upper surface 10a of the base 10 of the detection fixture 100 to place the product to be detected. Since the groove 11 has a bearing bottom surface 11a, a first side wall surface 11b and a second side wall surface 11c arranged at an angle, the bearing bottom surface 11a can be used to bear the product to be detected and the first side wall surface 11b and / or the second side wall surface 11c can be used as positioning surfaces to contact the product to be detected, so that the product to be detected can be effectively positioned, avoiding the situation that the placement direction of the product to be detected is skewed, and enabling the product to be detected to be kept in a fixed position each time it is placed, effectively improving the detection accuracy and detection efficiency of the product to be detected.
[0035] In order to avoid the situation that the product to be detected falls off from the groove 11 due to unstable placement or being impacted during the detection process, in some embodiments, refer to Figure 2 , the detection fixture 100 may further include a holding structure 20. The holding structure 20 is arranged in the groove 11. The holding structure 20 is configured to keep the product to be detected in the groove 11. Since the holding structure 20 is arranged in the groove 11 and the holding structure 20 is configured to keep the product to be detected in the groove 11, when the product to be detected is placed on the bearing bottom surface 11a, the purpose of restricting the position of the product to be detected in the groove 11 can be achieved through the holding structure 20, maintaining the stability of the product to be detected, avoiding the situation that the product to be detected is displaced due to unstable placement or being impacted during the detection process, which affects the detection structure, or even falls from the detection fixture 100, resulting in poor appearance of the product to be detected, thereby improving the detection efficiency and detection accuracy of the product to be detected.
[0036] In some possible embodiments, the holding structure 20 may include at least one of a magnetic structure, an elastic structure, and a vacuum adsorption structure. In one example, the holding structure 20 may be a magnetic structure such as a metal alloy magnet or a permanent magnetic material. Preferably, the holding structure 20 may be a high-magnetic neodymium magnet with higher magnetism, so that the product to be detected can be adsorbed as soon as it is placed in the groove 11, making the product to be detected fit the above-mentioned positioning surface. The structure is simple and easy to operate. There will be no situation where the product to be detected has a poor placement direction resulting in gaps, or the product to be detected has displacement or drops during the detection process, causing the detection to fail or the detection result to be incorrect. Thus, the detection accuracy and reproducibility of the product to be detected can be greatly improved. On the basis of improving the detection accuracy and reproducibility of the product to be detected, it is more convenient for the product to be detected to be flipped for detection on different planes, which is conducive to improving the detection speed.
[0037] In another example, the holding structure 20 may be a vacuum adsorption structure. The vacuum adsorption structure may include a vacuum generating device. Vacuum adsorption holes may be provided on the bearing bottom surface 11a of the groove 11. The vacuum generating device can make the vacuum adsorption holes generate negative pressure, so that a pressure difference is generated on both sides of the product to be detected to achieve the adsorption of the product to be detected, and thus the fixation of the product to be detected can also be realized.
[0038] It can be understood that the products to be detected may include, but are not limited to, camera-related products such as camera modules, lens barrels, and motors, or components of electronic products such as circuit boards and batteries. Thus, it can be seen that the forms of the products to be detected are various. That is to say, the detection fixture 100 of the present application can be applicable to detecting different products, and has a wider application range.
[0039] Taking the product to be detected as a camera module as an example, the camera module not only includes a lens barrel part but also a flexible cable part for electrical connection. In order to be compatible with more types of products to be detected with such irregular shapes, in some possible embodiments, the groove 11 is provided near the edge of the base 10, and the groove 11 penetrates through the edge of the base 10. Since the groove 11 is close to and penetrates through the edge of the base 10, for a product to be detected such as a camera module, the lens barrel part can be placed in the groove 11 so that the plane of the lens barrel fits the first side wall surface 11b and the second side wall surface 11c for effective positioning. The flexible cable part can be avoided by using one side that penetrates the edge, so that the detection fixture 100 will not have structural interference with part of the product to be detected. For regular products to be detected, they can be directly placed in the groove 11. In this way, whether it is a product to be detected with a flexible cable part such as a camera module or a regular product to be detected, the groove 11 can be used for positioning to complete the detection, so that the groove 11 can be compatible with more types of products to be detected and improve the versatility of the detection fixture 100.
[0040] In some possible embodiments, with continued reference to Figure 2 , there are a plurality of grooves 11, the plurality of grooves 11 are arranged at intervals, the groove 11 has an opening 11d facing the first direction X, the areas of the openings 11d of at least two grooves 11 are different, and / or the depths of at least two grooves 11 in the first direction X are different. Wherein, the first direction X is perpendicular to the upper surface 10a. It can be understood that the above-mentioned first direction X is the height direction (thickness direction) of the detection jig 100. That is, a plurality of grooves 11 are provided on the detection jig 100, the cross-sectional dimensions of the plurality of grooves 11 may be different, and the depths at which the plurality of grooves 11 are opened may also be different. By providing a plurality of grooves 11 with different sizes on the upper surface 10a of the detection jig 100, products to be detected with different sizes and different heights can be accommodated, so that more sizes and specifications of the products to be detected can be accommodated. In this way, it is not necessary to customize a dedicated detection jig 100 for each specification size of the product to be detected, which can reduce the number of times of frequently replacing the jig when detecting products to be detected with different specification sizes, not only can reduce costs, but also can improve the detection efficiency.
[0041] Refer to Figure 2 and Figure 3 , in some possible embodiments, there may be a plurality of grooves 11. Among the plurality of grooves 11, a first positioning groove 111 and a second positioning groove 112 are included. The bearing bottom surfaces 11a of the first positioning groove 111 and the second positioning groove 112 are respectively used to bear different surfaces of the product to be detected. Exemplarily, the bearing bottom surface 11a of the first positioning groove 111 can bear the bottom surface of the product to be detected, and the bearing bottom surface 11a of the second positioning groove 112 can bear the side surface of the product to be detected. In this way, after the front surface of the product to be detected is detected in the first positioning groove 111, it can be placed in the second positioning groove 112 area to detect the side surface. At the same time, another product to be detected can be placed in the first positioning groove 111 for synchronous detection. In this way, the grooves 11 on the detection jig 100 can be fully utilized to improve the detection efficiency.
[0042] In some possible embodiments, the second positioning groove 112 is located at the corner of the base 10. The second positioning groove 112 is opened at the corner of the base 10. That is, the second positioning groove 112 can penetrate at least two sides of the detection jig 100. In this way, the second positioning groove 112 can accommodate larger-sized products to be detected. For larger-sized products to be detected, the bearing bottom surface 11a of the second positioning groove 112 can bear a part of the product to be detected and be fixed by the holding structure 20, and the remaining part of the product to be detected can extend outside the detection jig 100.
[0043] It can be understood that taking the product to be detected as a camera module as an example, the side dimension of the camera module is usually smaller than the front dimension. The bottom surface of the camera module can be carried by the bearing bottom surface 11a of the second positioning groove 112 for front detection, and the side surface of the camera module can be carried by the bearing bottom surface 11a of the first positioning groove 111 for side detection. At this time, the size of the bearing bottom surface 11a of the second positioning groove 112 can be smaller than the size of the bearing bottom surface 11a of the first positioning groove 111.
[0044] Optionally, the first positioning groove 111 and the second positioning groove 112 can be multiple respectively. The multiple first positioning grooves 111 are arranged at intervals, and the multiple first positioning grooves 111 are set to have different opening sizes or depths to be compatible with more products to be detected. The multiple second positioning grooves 112 can be set according to the number of corners of the detection jig 100. For example, the detection jig 100 is a cuboid or a cube with four corners, and the second positioning grooves 112 are arranged at the four corners, and the second positioning grooves 112 can have different sizes to detect different sides of the product to be detected. Thus, the first positioning groove 111 and the second positioning groove 112 can place multiple products to be detected and detect different surfaces of multiple products to be detected at the same time, thereby improving the detection speed of the detection jig 100 and further facilitating the improvement of the detection efficiency.
[0045] It should be noted that the groove 11 can not only have the first side wall surface 11b and the second side wall surface 11c, but also have the third side wall surface and the fourth side wall surface. That is, the cross-sectional shape of the groove 11 can be a quadrilateral, a pentagon, etc. Exemplarily, for the first positioning groove 111, it can also have the third side wall surface, and the third side wall surface can be connected to the second side wall surface 11c and is opposite to the third side wall surface. At this time, the cross-sectional shape of the first positioning groove 111 is square. In this way, the product to be detected can use the bearing bottom surface 11a, the first side wall surface 11b and the second side wall surface 11c as the reference surfaces for positioning, or can use the bearing bottom surface 11a, the second side wall surface 11c and the third side wall surface as the reference surfaces, and the effective positioning effect can also be achieved.
[0046] In some possible implementation manners, continue to refer to Figure 2 and Figure 3, the holding structure 20 includes a first holding member 21 and a second holding member 22. The first holding member 21 is disposed in the first positioning groove 111 and on the bearing bottom surface 11a of the first positioning groove 111. The second holding member 22 is disposed in the second positioning groove 112 and on at least one of the bearing bottom surface 11a, the first side wall surface 11b, and the second side wall surface 11c of the second positioning groove 112. As can be seen from the foregoing, the first positioning groove 111 is disposed at the edge of the base 10, and the bearing bottom surface 11a of the first positioning groove 111 serves as the main bearing surface for the product to be detected. By disposing the first holding member 21 on the bearing bottom surface 11a, the first holding member 21 can have sufficient installation space, resulting in a better adsorption effect on the product to be detected. The second positioning groove 112 can be used to carry the side of the product for detection, and the depth of the second positioning groove 112 can be greater than the depth of the first positioning groove 111. Therefore, the second holding member 22 can be disposed on at least one of the bearing bottom surface 11a, the first side wall surface 11b, and the second side wall surface 11c of the second positioning groove 112.
[0047] Preferably, the second holding member 22 can be disposed on the first side wall surface 11b or the second side wall surface 11b of the second positioning groove 112, so that the second holding member has sufficient installation space to maintain the stability of the product to be detected fixed.
[0048] In some possible embodiments, an avoidance groove 12 is provided on the bearing bottom surface 11a. The avoidance groove 12 is disposed at the connection of the first side wall surface 11b and the second side wall surface 11c, and the avoidance groove 12 is used to avoid at least part of the structure of the product to be detected. By providing the avoidance groove 12 at the connection of the first side wall surface 11b and the second side wall surface 11c, when the product to be detected is placed in the groove 11 and contacts the first side wall surface 11b and the second side wall surface 11c, the corners of the product to be detected can be avoided. On the one hand, it can prevent the product to be detected from being knocked, and on the other hand, it can avoid the corners of the product to be detected, making different sides of the product to be detected fit more closely to the side wall surface of the groove 11, resulting in a better positioning effect.
[0049] In some possible embodiments, the bearing bottom surface 11a, the first side wall surface 11b, and the second side wall surface 11c are perpendicular to each other. Using the three mutually perpendicular surfaces as the positioning planes for the product to be detected can not only effectively position the product to be detected but also enable the product to be detected to be placed in the same position. When one side of the product to be detected is detected and it is found that repeated measurement is required, the three mutually perpendicular surfaces can also be used to position the product to be detected, realizing the reproducibility of the detection of the product to be detected.
[0050] Optionally, the flatness of the bearing bottom surface 11a, the first side wall surface 11b, and the second side wall surface 11c is 0 - 0.01 mm. For example, the flatness can be 0.003 mm, 0.005 mm, 0.007 mm, etc. By limiting the flatness of the bearing bottom surface 11a, the first side wall surface 11b, and the second side wall surface 11c of the groove 11 to be below 0.01 mm, a standard plane is formed for positioning the product to be detected. When the product to be detected uses these surfaces as the positioning reference, the position accuracy can be effectively guaranteed, which is conducive to improving the detection accuracy.
[0051] This application also discloses a detection device (not shown), which includes a detection device (not shown) and the above-mentioned detection jig 100. The detection device is configured to detect the product to be detected on the detection jig 100. It can be understood that the detection device can be a vision detection device, a CCD camera, etc. The detection jig 100 is placed within the shooting range of the detection device and fixed to prevent the detection jig 100 from shaking. Refer to Figure 4 , taking the camera module as an example, when it is necessary to detect the front and four side surfaces of the camera module, the first positioning groove 111 with a corresponding size can be selected according to the model of the camera module. The camera module is placed flat on the bearing bottom surface 11a of the first positioning groove 111, and the lens barrel part of the camera module faces the detection device. The first side wall surface 11b and the second side wall surface 11c are used to contact the side surface of the camera module for positioning. At this time, the first limiting member can fix the camera module to prevent shaking, thereby realizing the detection of the front appearance or size of the camera module. After detecting the front, the camera module can be taken out and placed into the second positioning groove 112 for side detection. Similarly, the first side wall surface 11b and the second side wall surface 11c of the second positioning groove 112 are used to position the camera module, thereby realizing the detection of the side surface of the camera module. When detection work is required, the product to be detected is placed in the groove 11. Among them, different second positioning grooves 112 can correspond to different side surfaces of the camera module to be detected.
[0052] It can be understood that the detection device with the above-mentioned detection jig 100 can also have all the effects of the above-mentioned detection jig 100, that is, the product to be detected is effectively positioned, the situation of the placement direction of the product to be detected being skewed is avoided, and each placement of the product to be detected can be kept in a fixed position, effectively improving the detection accuracy and detection efficiency of the product to be detected. Since the above technical effects have been introduced in detail in the embodiments of the detection jig 100, they will not be elaborated here.
[0053] The above has introduced in detail the detection fixture and the detection device disclosed in the embodiments of the present application. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the detection fixture and the detection device of the present application and its core idea; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
