Description

Technical Field

[0001] This application relates to the field of optical inspection technology, and in particular to an optical inspection imaging device. Background Technology

[0002] Traditional lighting methods lack suitable light sources for imaging surface defects on ring-shaped products. Both backlighting and low-angle ring lighting can only image severe damage, with minor defects remaining unclear. Backlighting uses a transmission method, which can image surface defects, but light scattering at the damaged area leads to inconsistent grayscale, making it ineffective for minor defects. Low-angle ring lighting can also image defects, but for minor defects, it must be installed very low, even inside the product, which is inconvenient. Therefore, patent CN212540159U discloses a "conical prism reflection optical imaging detection device" to address these issues. However, this patent only includes an adjustment knob for adjusting the position of the conical prism and imaging camera, which has a limited adjustment range and is applicable to a small area. Therefore, to solve these problems, this application provides an optical detection imaging device. Utility Model Content

Two side slides and a middle slide are slidably mounted on the frame. A prism seat is slidably embedded in the middle slide. The prism is mounted on the prism seat. An inner frame with an adjustable position to the middle slide is slidably sleeved on the outer side of the prism seat. An adjustment knob is rotatably connected to the inner frame and threadedly connected to the prism seat. Rotating the adjustment knob adjusts the position of the prism seat in the inner frame.

[0005] A wide range of adjustments can be achieved by sliding the side slides and the middle slides on the frame. An inner frame and a prism seat are set inside the middle slide, and a small range of adjustments can be achieved by using knobs and locking bolts, thereby improving the accuracy of the adjustment. This ensures sufficient range and accuracy.

[0006] Preferably, the adjustment knob is installed through the inner frame, and a bearing sleeve is installed on its outer side. The bearing sleeve is embedded in the inner frame, and the adjustment knob and the prism seat are threadedly connected.

[0007] Preferably, the intermediate slide block has grooves on its front and rear sides, and locking bolts that penetrate the inner frame are slidably embedded in the grooves. The inner frame is fixed in position by the locking bolts and the intermediate slide block.

[0008] Preferably, adjustment grooves are provided on the front and rear sides of the frame, and the side slides and the middle slides are slidably embedded in the adjustment grooves. The positions of the side slides and the middle slides on the frame are fixed by bolts.

[0009] Preferably, the imaging camera and the parallel light source are respectively mounted on two side slides, while the conical prism and the transparent glass are both mounted on the middle slide.

[0010] In summary, this application includes the following beneficial technical effects:

[0016] The following is in conjunction with the appendix Figure 1 - Figure 3 This application will be described in further detail.

[0017] Example 1:

[0018] An optical detection imaging device, referring to Figure 1 - Figure 3 The frame 1, from top to bottom, is equipped with an imaging camera 4, a conical prism 5, a transparent glass 6, and a parallel light source 8. Two side slide blocks 2 and one central slide block 3 are slidably mounted on the frame 1. A prism mount 9 is slidably embedded in the central slide block 3, and the prism is mounted on the prism mount 9. An inner frame 10, adjustable in position to the central slide block 3, is rotatably connected to the inner frame 10 and threadedly connected to the prism mount 9. Rotating the adjustment knob 7 adjusts the position of the prism mount 9 within the inner frame 10. The imaging camera 4 and the parallel light source 8 are respectively mounted on the two side slide blocks 2, while the conical prism 5 and the transparent glass 6 are both mounted on the central slide block 3.

[0019] A wide range of adjustments can be achieved by sliding the side slide block 2 and the middle slide block 3 on the frame 1. An inner frame 10 and a prism seat 9 are set inside the middle slide block 3, and a small range of adjustments can be achieved by using knobs and locking bolts 11, thereby improving the adjustment accuracy. This ensures sufficient range and accuracy.

[0020] An adjustment knob 7 is installed through the inner frame 10, and a bearing sleeve 71 is installed on its outer side. The bearing sleeve 71 is embedded in the inner frame 10. The adjustment knob 7 and the prism seat 9 are threadedly connected. When the adjustment knob 7 is rotated, due to the action of the bearing sleeve 71, the vertical position between the adjustment knob 7 and the inner frame 10 remains unchanged, thereby enabling the threaded drive prism seat 9 to change its position in the vertical direction.

[0021] The front and rear sides of the intermediate slide block 3 are provided with sliding grooves, and the locking bolts 11 that pass through the inner frame 10 are slidably embedded in the sliding grooves. The inner frame 10 is fixed in position with the intermediate slide block 3 by the locking bolts 11. After the locking bolts 11 are tightened, the friction between them and the outer wall of the intermediate slide block 3 increases, thereby achieving its stable position on the intermediate slide block 3.

[0022] Adjustment grooves 101 are provided on the front and rear sides of the frame 1. The side slides 2 and the middle slides 3 are slidably embedded in the adjustment grooves 101. The positions of the side slides 2 and the middle slides 3 on the frame 1 are fixed by bolts.

[0023] The foregoing description of an exemplary embodiment of an optical detection imaging device provided by this disclosure refers to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
