Description

Technical Field

[0001] This utility model belongs to the field of V-belt inspection, and in particular relates to a fully automatic V-belt surface defect inspection device. Background Technology

[0002] A V-belt, also known as a triangular belt, is a ring-shaped transmission belt with a trapezoidal cross-section. It gets its name from the fact that its working surfaces in contact with the pulleys are on both sides, relying on the friction between these surfaces to transmit power and motion. Its trapezoidal cross-section generates a greater wedging force, thus enabling it to transmit more power than a flat belt, and it is widely used in the mechanical field.

[0003] Traditional surface inspection equipment typically relies on human visual inspection, which is inefficient and prone to misjudgment. Furthermore, defects in V-belts can occur not only on the working surface (the trapezoidal inclined surface in contact with the pulley) but also on the non-working surface (back side), where cracks, wear, and foreign objects may be embedded. Traditional methods may require manual rotation of the belt, reducing inspection efficiency. Existing inspection equipment is also often difficult to effectively adapt to different specifications (length, model) of V-belts, usually requiring manual tension adjustment, which is inefficient and difficult to ensure consistency.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0016] Please see Figures 1 to 4 This utility model embodiment provides a fully automatic V-belt surface defect detection device for detecting the surface of a V-belt 5, including: A frame 1, on which a mounting bracket 11 is vertically mounted; Drive component 2, mounted on mounting bracket 11, is used to drive the V-belt 5 to move; Tensioning assembly 3, used in conjunction with drive assembly 2 to tension the V-belt 5, includes: The tensioning motor 31 is fixedly mounted on the side of the mounting bracket 11 via an "L"-shaped motor base 311; Mounting plate 33 is fixedly installed in movable groove 12 opened on the side of mounting frame 11. A lead screw 34 is also provided in movable groove 12. The two ends of the lead screw 34 are respectively rotatably installed on mounting plate 33 and one end of movable groove 12. The lead screw 34 is connected to the power output end of tension motor 31 through transmission unit 32. The movable block 35 is threadedly mounted on the lead screw 34, and a fixed shaft 351 is fixedly mounted on it. A tension wheel 36 is rotatably mounted on the fixed shaft 351, and the tension wheel 36 engages with the V-belt 5. Two acquisition components 4 are fixedly installed on the side of the mounting frame 11 and located on both sides of the working surface and non-working surface of the V-belt 5. They are connected to external analysis equipment via cables and are used to acquire image information of the working surface and non-working surface of the V-belt 5.

[0017] In practical application, the tensioning motor 31 is started, and the rotation of the lead screw 34 is controlled by the forward and reverse rotation of the tensioning motor 31 under the transmission action of the transmission unit 32. Based on the threaded engagement between the movable block 35 and the lead screw 34, the movable block 35 and the tensioning wheel 36 are driven to move along the axial direction of the lead screw 34. This, in conjunction with the drive assembly 2, achieves tensioning of the V-belt 5. The drive assembly 2 drives the V-belt 5 to rotate, and the set acquisition assembly 4 collects image information from both sides of the working surface and non-working surface of the V-belt 5 and converts it into electrical signals for transmission to external analysis equipment. This enables feature recognition and analysis of the images, and classification and judgment of surface defects.

[0018] In this embodiment, the tensioning component 3, in conjunction with the driving component 2, is used to tension the V-belt 5, which facilitates the image acquisition of the V-belt 5 by the acquisition component 4. At the same time, the tensioning component 3 is also easy to adapt to V-belts 5 of different specifications, which greatly improves the flexibility and applicability of the detection compared with existing detection equipment.

[0019] Please see Figure 2 In a preferred embodiment of this utility model, the driving component 2 includes: The drive motor 21 is fixedly mounted on the side of the mounting bracket 11; The drive shaft 22 is rotatably mounted in the mounting bracket 11, and its end is fixedly connected to the power output end of the drive motor 21. A drive wheel 23 is fixedly mounted on it, and the drive wheel 23 is engaged with the V-belt 5.

[0020] In practical application, the drive wheel 23 and tension wheel 36 work together to tension the V-belt 5, and the drive motor 21 drives the drive shaft 22 and drive wheel 23 to rotate, thereby driving the V-belt 5 to move, thus enabling continuous acquisition of the surface image of the V-belt 5 in conjunction with the fixed acquisition component 4.

[0021] Please see Figure 2 In another preferred embodiment of this utility model, the transmission unit 32 includes: The drive wheel 321 is fixedly installed at the power output end of the tensioning motor 31; Driven wheel 322 is fixedly installed at the end of lead screw 34 shaft, and its outer side is connected to drive wheel 321 through meshing chain 323.

[0022] In practical application, the tensioning motor 31 drives the driving wheel 321 to rotate, and the chain 323 wrapped around the outside of the driving wheel 321 and the driven wheel 322 drives the driven wheel 322 to rotate, which in turn drives the lead screw 34 to move. This, in turn, cooperates with the movable block 35 that is threaded with the lead screw 34 to control the position of the tensioning wheel 36.

[0023] In one embodiment, the transmission unit 32 can be configured in various ways, such as gear transmission, belt-pulley transmission, etc., as long as it can drive the lead screw 34 to rotate. This embodiment does not impose any additional limitations here.

[0024] Please see Figure 2 and Figure 3 In another preferred embodiment of the present invention, a limiting strip 121 is fixedly provided in the movable groove 12, and a limiting groove 352 adapted to the limiting strip 121 is fixedly provided at the position of the movable block 35 corresponding to the position of the limiting strip 121.

[0025] In practical applications, this embodiment uses a limiting strip 121 that is compatible with the limiting groove 352 to limit the movement of the movable block 35, thereby improving the stability of the movement of the movable block 35 and ensuring the coaxiality of the tension wheel 36 and the drive wheel 23, thus preventing the V-belt 5 from twisting and causing the analysis equipment to misjudge surface defects.

[0026] Please see Figure 1 , Figure 2 and Figure 4 In another preferred embodiment of the present invention, the acquisition component 4 includes a processing module 41, a camera 42 is fixedly mounted on the bottom of the processing module 41, and LED light sources 43 are symmetrically mounted on both sides of the camera 42.

[0027] In practical application, this embodiment uses a camera 42 to capture images, which are then transmitted to the analysis device via a processing module 41 and a cable. LED light sources 43 on both sides of the camera 42 illuminate the surface of the triangular belt 5, thereby increasing the brightness of the captured image and facilitating the analysis device to identify defects.

[0028] Please see Figure 4 In another preferred embodiment of the present invention, two reflectors 44 are symmetrically installed at the lower end of the processing module 41, and the two reflectors 44 are respectively inclinedly arranged outside the two LED light sources 43.

[0029] In practical applications, the tilted reflector 44 converges and reflects the light emitted by the LED light source 43, increasing the local brightness of the triangular strip 5 directly below the camera 42, highlighting surface defects to the maximum extent, and improving the reliability of the analysis results.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
