[0056] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0057] like Figure 1 As shown, according to an embodiment of the utility model, a portable visual inspection device is proposed, including: a lower frame 11, an upper frame 12, a first moving mechanism 13, a fixture module 14, a second moving mechanism 15 and a camera light source module 16; a first accommodating cavity is arranged in the lower frame 11; a second accommodating cavity is arranged in the upper frame 12, and the upper frame 12 and the lower frame 11 are rotatably connected through a flip axis 19; the first moving mechanism 13 is arranged in the first accommodating cavity; the fixture module 14 is used to fix the workpiece, and the fixture module 14 is rotatably arranged on the moving seat of the first moving mechanism 13; the second moving mechanism 15 is arranged in the second accommodating cavity; the camera light source module 16 is rotatably arranged on the moving seat of the second moving mechanism 15.

[0058] The portable visual inspection device provided by the embodiment of the utility model includes a lower frame 11, an upper frame 12, a first moving mechanism 13, a fixture module 14, a second moving mechanism 15 and a camera light source module 16. The fixture module 14 is rotatably connected to the moving seat of the first moving mechanism 13, the first moving mechanism 13 is arranged in the first accommodating cavity of the lower frame 11, and the first moving mechanism 13 drives the workpiece fixed on the fixture module 14 to move; the camera light source module 16 is rotatably connected to the moving seat of the second moving mechanism 15, the second moving mechanism 15 is arranged in the second accommodating cavity of the upper frame 12, and the second moving mechanism 15 drives the camera light source module 16 to move; the second moving mechanism 15 can adjust the position of the camera light source module 16, and the first moving mechanism 13 can adjust the positions of the fixture module 14 and the workpiece, so as to realize the camera light source module 16 to illuminate and take pictures of the workpiece from multiple angles, perform multi-angle visual inspection on the workpiece, and improve the visual inspection efficiency; the device The whole device adopts a flip-top box structure, the upper frame 12 is rotatably connected to the lower frame 11, and the lower frame 11 is used to support the entire device. On the one hand, by flipping the upper frame 12 to fold the device, the transportation height of the device can be lowered, the space occupied by the entire device can be reduced, and the overall structure of the device is compact, so that the device has both portability and detection efficiency; on the other hand, after the upper frame 12 is flipped and closed, it can protect the two internal moving mechanisms, the camera light source module 16 and the fixture module 14, ensuring that the internal components of the device will not be hit when the device is folded and transported; at the same time, the setting of the first accommodating cavity and the second accommodating cavity ensures that there is enough space inside the device after it is folded, which can ensure that when the upper frame 12 and the lower frame 11 are folded, the first moving mechanism 13, the fixture module 14 and the second moving mechanism 15, the camera light source module 16 do not interfere with each other, prevent the internal structure of the device from colliding with each other during transportation, and ensure the safety of the equipment during transportation.

[0059] It is understandable that before folding the upper frame 12, the jig module 14 and the camera light source module 16 can be adjusted to staggered positions by controlling the first moving mechanism 13 and the second moving mechanism 15 to ensure that when the upper frame 12 is folded, the internal components of the device will not interfere with each other or have hard contact, thereby preventing damage to the internal components after the device is folded.

[0060] Furthermore, the fixture module 14 is a suction cup mechanism or a clamping mechanism, so that the workpiece can be fixed on the moving seat of the first moving mechanism 13 through the fixture module 14 .

[0061] Furthermore, the flip angle of the upper frame 12 is 90 degrees, so that the upper frame 12 and the lower frame 11 remain perpendicular to each other after flipping, which facilitates the calculation of the displacement distance of the light source module.

[0062] like Figure 2As shown, in a feasible embodiment, the first moving mechanism 13 includes: a first linear moving mechanism 131 and an adapter plate 132; the first linear moving mechanism 131 includes a first slider, and the first linear moving mechanism 131 is arranged in the first accommodating cavity along the width direction of the lower frame 11; the adapter plate 132 is vertically arranged on the first slider, and the fixture module 14 is rotatably connected to the adapter plate 132 through the first rotating mechanism 17.

[0063] In this technical solution, the first linear moving mechanism 131 is arranged along the width direction of the lower frame 11, so that the first slider can slide along the width direction of the lower frame 11, and the jig module 14 is rotatably connected to the first rotating mechanism 17. The first rotating mechanism 17 is installed on the first slider through the adapter plate 132. The linear motion of the jig module 14 is controlled by the first linear moving mechanism 131, and the rotational motion of the jig module 14 is controlled by the first rotating mechanism 17, so that the workpiece fixed on the jig module 14 can move linearly along the width direction of the lower frame 11 and rotate at the same time, thereby increasing the range of motion of the workpiece, helping to increase the visual inspection angle range of the workpiece, and helping to improve the visual inspection efficiency.

[0064] It can be understood that the length direction of the upper frame 12 is consistent with the length direction of the lower frame 11, that is, the length direction of the front panel of the device in the unfolded state; when the device is in the folded state, the width direction of the upper frame 12 is consistent with the width direction of the lower frame 11; when the upper frame 12 is flipped and unfolded 90 degrees, the width direction of the upper frame 12 is the vertical direction.

[0070] In some examples, the second linear motion mechanism 151 includes a first ball screw and a first linear guide, and the nut of the first ball screw is connected to the second slider of the first linear guide, so that the second slider is driven to move by the first ball screw, thereby improving the movement accuracy of the second slider. The third linear motion mechanism 152 includes a second ball screw and a second linear guide, and the nut of the second ball screw is connected to the third slider of the second linear guide, so that the third slider is driven to move by the second ball screw, thereby improving the movement accuracy of the third slider, thereby improving the horizontal and vertical movement accuracy of the camera light source module 16, and helping to improve the detection accuracy of the camera light source module 16.

[0076] In this technical solution, the rotating shaft 19 is fixedly connected to the lower frame 11, and the bearing 20 is fixed to the upper frame 12. The rotating shaft 19 is connected to the inner ring of the bearing 20 to achieve rotational support for the upper frame 12, thereby improving the rotational flexibility between the upper frame 12 and the lower frame 11, preventing the upper frame 12 from getting stuck during rotation, and ensuring that the upper frame 12 can be quickly folded or flipped over and unfolded into place, thereby ensuring the compactness of the structure of the vertical and horizontal equipment.
