Description

Technical Field

[0001] This utility model belongs to the technical field of visual inspection, and in particular relates to a 6-axis fine-tuning structure for a visual inspection device. Background Technology

[0002] Visual inspection devices typically use industrial cameras to replace human eyes in performing functions such as identification, measurement, and positioning. They mainly consist of an inspection camera and a light source, and can replace manual labor in inspecting barcode characters, cracks, packaging, surface coating integrity, dents, etc. Using visual inspection devices can effectively improve the inspection speed and accuracy of production lines, increase production efficiency and quality, and reduce labor costs. However, existing visual inspection devices have limitations. Position adjustment is limited to only two or three of the X, Y, and Z directions, lacking rotational adjustment, resulting in a narrow adjustment range that cannot meet specific application requirements. Utility Model Content

[0003] The purpose of this invention is to solve at least one problem of the prior art by proposing a 6-axis fine-tuning structure for a visual inspection device.

[0004] To achieve the above objectives, this utility model proposes a 6-axis fine-tuning structure for a visual inspection device, comprising an X-axis linear motion module, a Y-axis linear motion module, a Z-axis linear motion module, a displacement adjustment slide, and a visual inspection device. The visual inspection device is mounted on the displacement adjustment slide and includes an inspection camera. The displacement adjustment slide is used to adjust the rotation angle of the inspection camera. The displacement adjustment slide is mounted on the slider of the Z-axis linear motion module and its Z-axis position is controlled by the Z-axis linear motion module. The Z-axis linear motion module is mounted on the slider of the Y-axis linear motion module and its Y-axis position is controlled by the Y-axis linear motion module. The Y-axis linear motion module is mounted on the slider of the X-axis linear motion module and its X-axis position is controlled by the X-axis linear motion module.

[0005] As an optional implementation, the X-axis linear motion module, Y-axis linear motion module, and Z-axis linear motion module are all electric lead screw and slider modules. The electric lead screw and slider module includes a support base, a motor mounted on the support base, and a slider. The support base is provided with a slide rail and a lead screw. The slider is slidably mounted on the slide rail and is threadedly connected to the lead screw. The motor is used to drive and control the rotation of the lead screw.

[0006] As an optional implementation, the device further includes a controller. The support bases of the Y-axis linear motion module and the Z-axis linear motion module are provided with a plurality of photoelectric switches. The sliders of the Y-axis linear motion module and the Z-axis linear motion module are provided with photoelectric sensing sheets that are compatible with the photoelectric switches. The controller is electrically connected to the photoelectric switches, the motors of the X-axis linear motion module, the Y-axis linear motion module, and the Z-axis linear motion module, and controls the working state of the motors.

[0007] As an optional implementation, the displacement adjustment slide includes a first manual fine-tuning module, a second manual fine-tuning module, and a third manual fine-tuning module. The second manual fine-tuning module is mounted on the first manual fine-tuning module, and the first manual fine-tuning module is used to adjust the rotation angle of the second manual fine-tuning module in the left-right direction. The third manual fine-tuning module is mounted on the second manual fine-tuning module, and the second manual fine-tuning module is used to adjust the rotation angle of the third manual fine-tuning module in the front-back direction. The detection camera is mounted on the third manual fine-tuning module, and the third manual fine-tuning module is used to adjust the horizontal rotation angle of the detection camera.

[0008] As an optional implementation, the detection camera is mounted on a third manual fine-tuning module via a camera bracket.

[0009] As an optional implementation, the third manual fine-tuning module is used to adjust the detection camera at any angle of 360° along the horizontal direction.

[0010] As an optional implementation, the angle adjustment range of both the first manual fine-tuning module and the second manual fine-tuning module is ±15°.

[0011] As an optional implementation, the first manual fine-tuning module, the second manual fine-tuning module, and the third manual fine-tuning module are all provided with locking components. The locking components are used to fix the corresponding second manual fine-tuning module, the third manual fine-tuning module, and the detection camera after they are adjusted to a predetermined angle.

[0012] The beneficial effects of this utility model are as follows: By mounting the vision inspection device on a displacement adjustment slide, which is then mounted on the slider of the Z-axis linear motion module, and the Y-axis linear motion module is mounted on the slider of the X-axis linear motion module, the position of the vision inspection device can be adjusted in the X, Y, and Z directions through the interlocking of the X, Y, and Z-axis linear motion modules. The displacement adjustment slide can also be used to adjust the rotation angle of the vision inspection device, enabling the vision inspection device to achieve both movement and rotational position adjustment. This allows for a wider range of position adjustment for the vision inspection device, meeting the vision inspection requirements of different products.
