[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0024] like Figures 1 to 4 As shown, in one embodiment of this utility model, the base 1 and the guide unit base 1 are a set of rigid frames arranged opposite to each other to support the overall structure.

[0025] In one embodiment of this utility model, the front webbing guide unit 2 includes a front column 21 fixed on the base 1, and a first guide wheel 22 is rotatably mounted on the front column 21 for guiding the webbing into the detection area.

[0026] In one embodiment of this utility model, the central webbing guide unit 3 includes a central column 31 fixed on the base 1, and a second guide wheel 32 is rotatably mounted on the central column 31 for further adjusting the transmission path of the webbing.

[0027] In one embodiment of the present invention, the rear webbing guide unit 4 includes a rear column 41 fixed on the base 1, and a roller 42 is rotatably mounted on the rear column 41 for driving the final stage deceleration output of the webbing.

[0028] In one embodiment of this utility model, the servo motor (not shown in the figure) of the drive component is mounted coaxially on the middle webbing guide unit 3 to provide power output. The gear transmission system includes a large gear 5 coaxially mounted on the middle webbing guide unit 3 and a small gear 6 coaxially mounted on the rear webbing guide unit 4. The two gears mesh and transmit power, controlling the rotational speed of the roller 42 through the reduction ratio to achieve reduced webbing output.

[0029] In one embodiment of this utility model, the support component and the detection component are: the support component includes an extended column 7 vertically fixed on the base 1, the top of the column is connected to a crossbeam 8, and the detection component is fixed below the crossbeam 8 by a first flange plate 9.

[0030] Inspection component - ball screw linear module 10: The main body is connected to the first flange plate 9 through the second flange plate 12, and its slide can move laterally (in the direction of webbing width); the support profile 11 is fixed to the front of the main body of the ball screw linear module 10, a vision inspection unit is installed on the front surface, and an exposure lamp 13 that can rotate around the axis is provided at the bottom for adjusting the illumination angle.

[0031] The visual inspection unit includes a guide mechanism comprising a guide rail 14 and a slide fixed to the front panel 19 to ensure adjustment stability; a manual screw adjustment mechanism comprising a pair of bearing seats 15, a rotatable screw 16, and a threaded nut 17, which drives the front panel 19 to make longitudinal fine adjustments by rotating the screw 16. A visual inspection camera 18 is mounted on the front panel 19 and is used to acquire images of the webbing surface. The visual inspection camera 18 is a commonly used component in this field, and its structure, usage, and principle will not be described in detail here.

[0032] The specific working principle of this utility model is as follows:

[0033] 1. Webbing transmission path

[0034] The webbing passes sequentially through the front guide wheel, the second guide wheel 32, and the roller 42, moving at a constant speed under the gear transmission of the drive assembly. The servo motor reduces speed through the meshing of the large gear 5 and the small gear 6, precisely controlling the rotational speed of the roller 42 to ensure smooth webbing delivery.

[0035] 2. Detection component adjustment process

[0036] Lateral adjustment: The slide of the ball screw linear module 10 drives the second flange plate 12 to move laterally, so that the vision inspection camera 18 covers the entire width range of the webbing.

[0037] Longitudinal fine adjustment: By manually rotating the screw 16, the front panel 19 is driven to move longitudinally along the guide rail 14, and the detection position of the camera is precisely adjusted.

[0038] Light compensation: Rotate the exposure lamp 13 to adjust its illumination angle to avoid reflections or shadows on the webbing surface interfering with the test results.

[0039] 3. Testing Process

[0040] The visual inspection camera 18 acquires real-time images of the surface of the webbing, and transmits the image data to an external processing system to achieve automated quality inspection. The external processing system is existing technology in this field. Any processing system that achieves automated quality inspection based on the surface images acquired by the visual inspection camera can be applied to this application, and its methods and principles will not be elaborated here.

[0041] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
