[0037] Example 1
[0038] In view of the aforementioned deficiencies in existing visual inspection devices, the applicant, drawing upon years of extensive practical experience and expertise in the design and manufacture of such products, combined with applied theory, has actively engaged in research and innovation, hoping to create a technology that can address the deficiencies of the existing technology and make visual inspection devices more practical. Through continuous research and design, as well as repeated trial production and improvements, the applicant has finally created the present utility model, which has proven to be of practical value.
[0039] The embodiment of the present utility model provides a visual inspection device, which can help improve the inspection efficiency of workpieces.
[0040] Please refer to Figures 1 to 2 The visual inspection device includes: a support member 1, which can be a support frame, a support plate or other supporting structure; a detection camera 2; a total reflection mirror 3, which can be rotatably installed on the support member 1; when the total reflection mirror 3 is rotated to a first rotation angle, the total reflection mirror 3 is used to reflect the image on the first workstation to the detection camera 2; when the total reflection mirror 3 is rotated to a second rotation angle, the total reflection mirror 3 is used to reflect the image on the second workstation to the detection camera 2.
[0041] Specifically, in this embodiment, after the detection camera 2 completes the photo inspection of the workpiece on the first station, the workpiece on the first station will need to perform a process of removing the workpiece and placing a new workpiece. During this process, the total reflection mirror 3 rotates to the second rotation angle and the detection camera 2 performs photo inspection on the workpiece on the second station; after the detection camera 2 completes the photo inspection of the workpiece on the second station, the workpiece on the second station will need to perform a process of removing the workpiece and placing a new workpiece. During this process, the total reflection mirror 3 rotates to the first rotation angle and the detection camera 2 performs photo inspection on the workpiece on the first station, and the above process is repeated.
[0042] In this embodiment, the utilization efficiency of the inspection camera 2 can be effectively improved, thereby improving the inspection efficiency of the visual inspection device. It should also be noted that the workpiece on the first station can be the same as the workpiece on the second station, or can be different.
[0043] It should be noted here that the total reflection mirror 3 can directly reflect the image of the workpiece on the first workstation to the detection camera 2, or it can indirectly reflect the image of the workpiece on the first workstation to the detection camera 2; the total reflection mirror 3 can directly reflect the image of the workpiece on the second workstation to the detection camera 2, or it can indirectly reflect the image of the workpiece on the second workstation to the detection camera 2.
[0044] Optionally, a first beam splitter 4 and a second beam splitter 5 are further mounted on the support member 1; the first beam splitter 4 and the second beam splitter 5 are mounted on opposite sides of the total reflection mirror 3; when the total reflection mirror 3 is rotated to a first rotation angle, the image at the first station is reflected to the total reflection mirror 3 via the first beam splitter 4; when the total reflection mirror 3 is rotated to a second rotation angle, the image at the second station is reflected to the total reflection mirror 3 via the second beam splitter 5. In this embodiment, the provision of the first beam splitter 4 and the second beam splitter 5 allows for better planning of the positions of the first and second stations and provides more options for the installation position of the inspection camera 2.
[0045] Optionally, the first beam splitter 4 and the second beam splitter 5 are respectively installed on two opposite sides of the total reflection mirror 3, and the first beam splitter 4 and the second beam splitter 5 are symmetrically arranged. Figure 1 As shown, when the total reflection mirror 3 is at the first rotation angle, it is located at the position of the rectangle formed by the solid line. When the total reflection mirror 3 is at the second rotation angle, it is located at the position of the rectangle formed by the double-dotted line. Figure 1 It should also be noted that the image of the workpiece on the first station is reflected to the total reflection mirror 3 along the direction of the arrow on the dotted line, and the image of the workpiece on the second station is reflected to the total reflection mirror 3 along the direction of the arrow on the dotted line.
[0046] Alternatively, as Figure 1 As shown, the difference between the first rotation angle and the second rotation angle is 90°, that is, each time the total reflection mirror 3 rotates 90°, the state of the total reflection mirror 3 is switched.
[0047] Optionally, a rotation drive device is provided on the support member 1 for adjusting the rotation angle of the total reflection mirror 3, and the rotation axis of the rotation drive device is fixedly connected to the total reflection mirror 3. In this embodiment, the rotation drive device drives the total reflection mirror 3 to rotate, thereby switching the total reflection mirror 3 to a first rotation angle state or a second rotation angle state. In one specific embodiment, the rotation drive device is a rotary cylinder; in another specific embodiment, the rotation drive device is a servo motor.
[0048] Optionally, the detection camera 2 is located directly below or above the total reflection mirror 3, so that the workpiece can remain in a horizontal state at the first station or the second station, which makes loading and unloading of the workpiece more convenient.
[0049] Optionally, the first beam splitter 4 and the second beam splitter 5 are located on the same side of the total reflection mirror 3, as shown in FIG. Figure 2 As shown. Figure 2 In the figure, when the total reflection mirror 3 is at the first rotation angle, it is located at the position of the rectangle formed by the solid line indicated, and when the total reflection mirror 3 is at the second rotation angle, it is located at the position of the rectangle formed by the double-dotted line.
[0050] Optionally, the visual inspection device also includes a first light board 6 and a second light board 7; the first light board 6 is arranged on the top side of the first spectrometer 4, and the light of the first light board 6 shines on the workpiece at the first workstation through the first spectrometer 4; the second light board 7 is arranged on the top side of the second spectrometer 5, and the light of the second light board 7 shines on the workpiece at the second workstation through the second spectrometer 5.
[0051] Specifically, the first light board 6 and the second light board 7 are provided to improve the lighting effect on the workpiece, so that the detection camera 2 can better detect surface defects of the workpiece.
