Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a rotating detection device for surface defects of a cooling fan impeller. Background Technology

[0002] A cooling fan impeller is a component used for heat dissipation. It is mainly used to reduce the temperature of equipment or systems through airflow. A cooling fan impeller is usually composed of blades, a shaft, and a casing. When a motor or other power source drives the impeller to rotate, the blades push the surrounding air to create airflow. During the rotation of the blades, a pressure difference is created, which draws air in from one side and discharges it from the other side, forming an airflow. When the airflow passes through the heat sink or other heat dissipation components, it can carry away heat and achieve the purpose of heat dissipation.

[0003] In the quality inspection of cooling fan impellers, it is necessary to use equipment such as vision inspection instruments to scan and photograph the impeller surface to determine whether there are defects on the impeller surface. Usually, the impeller is horizontally fixed on the inspection table for defect detection. However, such inspection tables generally lack the ability to rotate. When inspecting the back and front of the cooling fan impeller, the position of the impeller needs to be manually adjusted, which makes it impossible to carry out continuous inspection and reduces the efficiency of detecting defects on the fan impeller surface. Therefore, a rotating detection device for surface defects of cooling fan impellers is proposed. Utility Model Content

[0016] In a preferred embodiment of the rotating detection device for surface defects of a cooling fan impeller described in this utility model, multiple rubber strips are fixedly connected to the opposite surfaces of the two clamping plates, and the multiple rubber strips are distributed at equal intervals on the corresponding clamping plates.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention.

[0032] Example 1

[0033] Reference Figures 1-3 The first embodiment of this utility model provides a rotating detection device for surface defects of a cooling fan impeller, comprising: a support unit 100, a detection unit 200, a rotating unit 300, and a clamping unit 400.

[0034] The support unit 100 includes a support platform 101 and a support frame 102 fixedly connected to the top of the support platform 101.

[0035] The detection unit 200 is mounted on the support frame 102 and is used to detect surface defects of the fan impeller.

[0036] The rotating unit 300 is mounted on the support platform 101. The rotating unit 300 is equipped with a clamping unit 400. The rotating unit 300 is used to drive the clamping unit 400 to rotate and flip. The clamping unit 400 is used to clamp and fix the fan impeller.

[0037] The cooling fan impeller is clamped and fixed below the detection unit 200 by the clamping unit 400. The rotating unit 300 can drive the cooling fan impeller to rotate, so as to detect whether the fan blades of the fan impeller crack or twist due to design defects or defects on the surface of the fan blades during rotation. This is to detect the quality of the fan blades and their stability during rotation. The rotating unit 300 can also flip the cooling fan impeller, so that the front and back of the cooling fan impeller can be detected continuously, so that the detection unit 200 can perform all-round detection of the surface of the cooling fan impeller, thereby improving the detection efficiency.

[0038] Example 2

[0039] Reference Figure 1 and Figure 2 This is the second embodiment of the present invention. Unlike the previous embodiment, the detection unit 200 includes an electric telescopic rod 201 fixedly connected to the top of the support frame 102. The output end of the electric telescopic rod 201 slides through the support frame 102 and is fixedly connected to a vision inspection instrument 202.

[0040] The visual inspection instrument 202 converts the target to be inspected into an image signal through an image acquisition device, and then uses a dedicated image processing system to process and analyze these signals. By extracting the features of the target, it can quickly and accurately identify minute defects on the surface. The electric telescopic rod 201 is used to drive the visual inspection instrument 202 to move up and down, so that the visual inspection instrument 202 can approach the fan impeller and inspect its surface defects.

[0041] In addition, a fixing rod 203 is fixedly connected to one side of the visual inspection instrument 202, and a supplementary light 204 is fixedly installed at the bottom of the fixing rod 203.

[0042] Because the blades of the fan impeller are curved, the roots of some blades are blocked at the connection points with the shaft core, resulting in dim lighting in some areas of the fan impeller. The supplementary light 204 can provide supplementary lighting to the fan impeller without affecting the detection of the vision inspection instrument 202, thus facilitating the detection of the dark areas on the surface of the fan impeller by the vision inspection instrument 202.

[0043] Example 3

[0044] Reference Figure 1 and Figure 3 This is the third embodiment of the present invention. Unlike the previous embodiment, the rotating unit 300 includes a drive motor 301 fixedly installed at the bottom of the support platform 101. The output end of the drive motor 301 passes through the support platform 101 and is fixedly connected to a U-shaped plate 302. The rotating unit 300 also includes a flipping component 303 for flipping the fan impeller.

[0045] The drive motor 301 is used to drive the U-shaped plate 302 to rotate. The U-shaped plate 302 drives the clamping unit 400 to rotate. When the fan impeller itself does not have a fan blade motor or cannot rotate, the drive motor 301 drives the fan impeller to rotate in order to detect the state of the fan blades during rotation. When there is a design defect in the fan blades, the fan blades may vibrate or break, so that the design defect of the fan blades can be detected in time. When there are defects such as cracks and gaps on the surface of the fan blades, rotating the fan impeller can enlarge the defect area so that the defect location can be observed in time.

[0046] Specifically, the flipping assembly 303 includes a servo motor 3031 fixedly installed on one side of the U-shaped plate 302. The output end of the servo motor 3031 passes through the U-shaped plate 302 and is fixedly connected to a rectangular frame 3032.

[0047] Once the fan impeller is clamped and fixed by the clamping unit 400, the servo motor 3031 can drive the rectangular frame 3032 to deflect, thereby deflecting the fan impeller through the servo motor 3031. This allows for continuous detection of the front and back of the cooling fan impeller, enabling the vision inspection instrument 202 to perform all-round detection of surface defects on the fan impeller.

[0048] Example 4

[0049] Reference Figure 1 and Figure 3 This is the fourth embodiment of the present invention. Unlike the previous embodiment, the clamping unit 400 includes two electric push rods 401 that are respectively fixedly installed on both sides of the rectangular frame 3032. The output ends of the two electric push rods 401 slide through the rectangular frame 3032 and are fixedly connected to the clamping plate 402.

[0050] Two electric actuators 401 are symmetrically distributed, and two clamping plates 402 are located within a rectangular frame 3032. By placing the fan impeller between the two clamping plates 402, the two electric actuators 401 can move their respective clamping plates 402 closer together to clamp and fix the fan impeller, so that the rotating unit 300 can rotate and flip. The two electric actuators 401 can also move their respective clamping plates 402 further apart, and then the fan impeller can be removed from between the two clamping plates 402.

[0051] In addition, multiple rubber strips 403 are fixedly connected to the opposite surfaces of the two clamping plates 402, and the multiple rubber strips 403 are distributed at equal intervals on the corresponding clamping plates 402.

[0052] The rubber strip 403 is used to increase the friction between the clamping plate 402 and the fan impeller to prevent the fan impeller from falling off between the two clamping plates 402. The rubber strip 403 can also protect the fan impeller to prevent the clamping plate 402 from squeezing marks on the surface of the fan impeller.

[0053] It should be noted that a sponge pad 404 is fixedly connected to the bottom of the inner wall of the U-shaped plate 302, and a groove is provided on the top of the sponge pad 404.

[0054] After the inspection is completed, the worker holds the fan impeller in his hand. Then the two clamping plates 402 move away from each other and no longer clamp the fan impeller, so the fan impeller can be taken out. If the worker does not hold it firmly and the fan impeller slips from his hand, the fan impeller will fall into the groove of the sponge pad 404. The sponge pad 404 prevents the fan impeller from being bumped or damaged. The groove can limit the falling fan impeller and prevent it from rolling or displacing on the surface of the sponge plate.

[0055] During use, hold the fan impeller and place it between two clamping plates 402. Then, two electric push rods 401 push their respective clamping plates 402 to clamp and fix the fan impeller. Then, release the fan impeller and turn on the supplementary light 204. Then, the electric telescopic rod 201 drives the vision inspection instrument 202 to descend to detect defects on the surface of the fan impeller. When the fan impeller itself does not have a fan blade motor or cannot rotate, the drive motor 301 drives the fan impeller to rotate to detect the state of the fan blades during rotation, thereby timely detecting design defects or quality defects of the fan blades.

[0056] After the single-sided inspection of the fan impeller is completed, the electric telescopic rod 201 drives the vision inspection instrument 202 to rise. Then, the servo motor 3031 drives the rectangular frame 3032 to rotate 180 degrees. Next, the electric telescopic rod 201 drives the vision inspection instrument 202 to descend again to perform a comprehensive defect inspection on both sides of the fan impeller. After the inspection is completed, the electric telescopic rod 201 drives the vision inspection instrument 202 to rise and reset. Then, holding the fan impeller, the two electric push rods 401 pull their respective clamping plates 402 away from each other and no longer clamp the fan impeller. The fan impeller can then be removed from between the two clamping plates 402.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
