Description

Technical Field

[0001] This application relates to the field of testing equipment, and in particular to a device for testing product dimensions and geometric tolerances. Background Technology

[0002] In existing industrial production, dimensional inspection and geometric tolerance inspection of products are key aspects of quality control. However, traditional inspection methods typically require distributing these two inspection functions across multiple workstations, resulting in complex and costly equipment that occupies a large space. Furthermore, manual operation is subject to the influence of operators on the accuracy of inspections and is inefficient.

[0003] Therefore, this application studies a product size and geometric tolerance detection device that has a simple structure, occupies little space, and better ensures detection accuracy and efficiency. Utility Model Content

[0004] In order to achieve a simple structure, small footprint, and better ensure detection accuracy and efficiency, this application provides a product size and geometric tolerance detection device.

[0005] This application provides a product dimension and geometric tolerance inspection device, which adopts the following technical solution:

[0006] A product dimension and geometric tolerance inspection device includes a data acquisition structure. The data acquisition structure includes three sets of acquisition mechanisms and a backlight. The acquisition mechanisms are used to acquire the corner features of the product. The three sets of acquisition mechanisms include a first acquisition component, a second acquisition component, and a third acquisition component. The first acquisition component, the second acquisition component, and the third acquisition component are longitudinally distributed. The backlight is positioned opposite to the second acquisition component. During acquisition, the product is located horizontally between the second acquisition component and the backlight, and vertically between the first acquisition component and the second acquisition component.

[0007] By adopting the above technical solution, the acquisition mechanism collects the corner features of the product and uploads them to the control system for processing to obtain the product size and geometric tolerances. The product size detection and geometric tolerance detection functions are integrated into the same device. Through the coordinated work of three sets of acquisition mechanisms and backlight, comprehensive acquisition of the corner features of the product is achieved. The product structure is simple, which allows for detection in a small space. Furthermore, intelligent acquisition better ensures detection accuracy and efficiency.

[0008] Optionally, the first acquisition component includes a first camera, a first lens, and a first corner coaxial light source connected in sequence; the second acquisition component includes a second camera and a second lens connected in sequence; the third acquisition component includes a third camera, a third lens, and a third corner coaxial light source connected in sequence; the first corner coaxial light source and the third corner coaxial light source are arranged facing each other; the second lens faces the backlight and is coaxially arranged at the center; the product is placed between the second lens and the backlight, and is located between the first corner coaxial light source and the third corner coaxial light source.

[0009] By adopting the above technical solution, a first and a third coaxial corner light source are respectively equipped, and the two are arranged facing each other. This design enables the device to perform symmetrical inspection from both sides of the product, which is particularly suitable for the precise measurement of the corner features of the product. The second lens is directly facing the backlight and is coaxially set with the center of the backlight, which can clearly capture the horizontal features of the product. This not only improves the accuracy of the inspection, but also effectively utilizes the uniform illumination provided by the backlight to further improve the quality of the inspection image, and makes full use of space to ensure high inspection efficiency.

[0010] Optionally, a lens mounting plate is also included, which has three lens holes with the centers of the lens holes located on the same vertical line. The first lens and the third lens are installed in the upper and lower lens holes in sequence, and the second lens moves in the middle lens hole.

[0011] By adopting the above technical solution, the positional deviation between lenses is reduced, thereby improving the alignment accuracy and consistency of the detected images.

[0012] Optionally, it also includes an upper mounting plate and a lower mounting plate connected to both ends of the lens mounting plate, wherein the first corner coaxial light source is mounted on the side of the upper mounting plate facing the lower mounting plate, and the third corner coaxial light source is mounted on the side of the lower mounting plate facing the upper mounting plate.

[0013] Optionally, a front mounting plate is connected to one side of the upper mounting plate, and the backlight is mounted on the front mounting plate.

[0014] Optionally, a camera mounting plate is further provided between the upper mounting plate and the lower mounting plate. The camera mounting plate has two camera mounting holes and a clearance groove. The clearance groove is located between the two camera mounting holes. The first camera and the third camera are respectively mounted in the two camera mounting holes. The second acquisition component moves between the clearance groove and the lens hole.

[0015] Optionally, the acquisition mechanism further includes a first adjustment mechanism for adjusting the position of the second acquisition component.

[0016] Optionally, a second adjustment mechanism may also be included, which is used to adjust the position of the acquisition structure.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] After the acquisition mechanism collects the corner features of the product, it uploads the data to the control system for processing to obtain the product size and geometric tolerances. The product size detection and geometric tolerance detection functions are integrated into the same device. Through the coordinated work of three acquisition mechanisms and a backlight, comprehensive acquisition of the corner features of the product is achieved. The product structure is simple, which allows for detection in a small space. Furthermore, intelligent acquisition better ensures detection accuracy and efficiency.

[0019] Equipped with a first and a third coaxial corner light source, respectively, and oriented towards each other, this design allows the device to perform symmetrical inspection from both sides of the product. It is particularly suitable for the precise measurement of the product's corner features. The second lens, directly facing the backlight and coaxially aligned with the center of the backlight, can clearly capture the product's horizontal features. This not only improves the accuracy of the inspection but also effectively utilizes the uniform illumination provided by the backlight, further enhancing the quality of the inspection image. Furthermore, it makes full use of space, ensuring high inspection efficiency.

[0020] Reducing positional deviations between lenses improves the alignment accuracy and consistency of the detected images. Attached Figure Description

The centers of the lens holes 7 are located on the same vertical line. The first lens 32 and the third lens 52 are installed in the upper and lower lens holes 7 in sequence to reduce the positional deviation between the lenses. The second lens 42 moves in the middle lens hole 7.

[0029] In some embodiments, the product size and geometric tolerance detection device further includes an upper mounting plate 8 and a lower mounting plate 9 connected to both ends of the lens mounting plate 6.

The driving component 18 can be a cylinder. In this embodiment, the driving component 18 uses gear rotation to achieve fine adjustment, and a scale is provided on the guide rail 17 for more precise adjustment. The driving component 18 drives the moving plate 14 to move the second acquisition component 4 along the guide rail.

The second adjustment mechanism 15 is used to adjust the position of the acquisition structure 1. The position of the acquisition structure 1 can be adjusted by the second adjustment mechanism 15 to better suit different products.
