[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See also Figures 1 to 5 , which is a cooling fan power line measuring device according to an embodiment of the utility model, includes a machine platform 10, a wire drawing assembly 20 installed on the machine platform 10, a visual assembly 30 installed at one end of the wire drawing assembly 20, and a blanking assembly 40 installed above the wire drawing assembly 20.

[0030] The wire drawing assembly 20 includes a material moving linear module 21 installed on the top surface of the machine 10, a fixed plate 22 installed on the slide of the material moving linear module 21, a fixture 23 installed on one end of the fixed plate 22, a wire drawing linear module 24 installed on the other end of the fixed plate 22, a tension sensor 25 installed on the slide of the wire drawing linear module 24, and a hook plate 26 connected to one end of the tension sensor 25; the hook plate 26 is arranged adjacent to the fixture 23. When working, the cooling fan body is placed inside the fixture 23, and the cooling fan power line is hooked on the hook plate 26. The wire drawing linear module 24 is used to drive the hook plate 26 away from the fixture 23, so that the cooling fan power line can be straightened, which is convenient for the visual component 30 to shoot.

[0031] In this embodiment, one end of the tension sensor 25 is fixedly connected to the slide of the wire pulling linear module 24, and the other end of the tension sensor 25 is fixedly connected to the hook plate 26. By setting the tension sensor 25, the tension applied by the wire pulling linear module 24 to the cooling fan power line can be monitored in real time. When the tension exceeds the preset safety threshold, the tension sensor 25 will send a warning signal, and the system will brake the wire pulling linear module 24 to avoid wire breakage.

[0032] The visual component 30 includes a column 31 installed at one end of the material transfer linear module 21, and a bar light source 32 and an industrial camera 33 that are liftably connected to the column 31; the industrial camera 33 is located above the bar light source 33. Specifically, the light emitting surface of the bar light source 32 faces the material transfer linear module 21, and the industrial camera 33 is located above the material transfer linear module 21.

[0033] The function of the strip light source 32 is to illuminate the cooling fan power cord, ensuring that the outline of the cooling fan power cord is clearly visible during the shooting process, and there are no shadows or dark areas to interfere with visual recognition. Uniform lighting conditions are essential for the industrial camera 33 to capture clear and accurate images. The industrial camera 33 is located above the material transfer linear module 21, and its main function is to capture images of the cooling fan power cord. By capturing high-definition images, the industrial camera 33 can accurately reflect the actual length and shape of the cooling fan power cord. These images are then transmitted to the image processing system or measurement software for further analysis and processing. During the image processing process, the system may apply edge detection, image segmentation and other technologies to identify and extract the length information of the cooling fan power cord. These technologies can accurately measure the length of the cooling fan power cord, thereby providing users with accurate data. In addition, by comparing data at different times or different production batches, the length changes of the cooling fan power cord can also be monitored, and potential problems can be discovered and solved in a timely manner.

[0034] In this embodiment, the industrial camera 33 is coaxially connected to a zoom lens 34. The main function of the zoom lens 34 is that it can provide magnification effects of different magnifications. By adjusting the magnification of the lens, the image captured by the industrial camera 33 can be magnified or reduced to varying degrees, thereby adapting to cooling fan power cords of different lengths. This feature allows the system to easily cope with cooling fan power cords of different lengths without frequently changing the lens or adjusting the camera position, greatly improving the convenience and efficiency of measurement.

[0035] The unloading assembly 40 includes a gantry 41 installed above the end of the material transfer linear module 21 away from the visual assembly 30, a transverse linear module 42 installed on the gantry 41, a longitudinal linear module 43 connected to the slide of the transverse linear module 42, a bearing plate 44 connected to the slide of the longitudinal linear module 42, a suction cup 45 installed on one side of the bearing plate 44, and an unloading conveyor belt 46 located at one side of the bottom end of the gantry 41. The suction cup 45 is located above the fixture 23, and the suction cup 45 is used to suck the cooling fan body to transfer the measured cooling fan body to the unloading conveyor belt 46.

[0036] Furthermore, the unloading assembly further includes a pneumatic clamp 47 movably mounted on the carrier plate 44, the pneumatic clamp 47 being disposed adjacent to the suction cup 45, and the pneumatic clamp 47 being used to clamp the power cord of the cooling fan. Specifically, considering that the power cord of some cooling fan bodies is relatively long, during the suction transfer process of the suction cup 45, the pneumatic clamp 47 is used to clamp the power cord of the cooling fan, so as to avoid the cooling fan power cord from being entangled with other components and prevent accidents.

[0037] In this embodiment, the pneumatic clamping jaw 47 is slidably connected to the carrying plate 44 via a guide rail pair.

[0038] In this embodiment, the length direction of the transverse linear module 42 is consistent with the length direction of the wire pulling linear module 24 .

[0039] The above-mentioned cooling fan power line measuring device has a simple structure and is easy to use. The cooling fan body is placed inside the fixture 23, and the wire pulling linear module 24 drives the hook plate 26 to straighten the cooling fan power line. The cooling fan power line is photographed using an industrial camera 33, which is convenient for the background to calculate the length, replacing manual measurement and greatly improving the measurement accuracy.

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
