[0050] Reference Figure 1-Figure 10 According to some embodiments of the present invention, the fan detection device includes a frame 100, a dynamic balance test device 200, a weight detection device 300, a vibration detection device 400 and a master control device 500.

[0051] A testing platform 130 is disposed on the rack 100 , and the testing platform 130 is used to place the fan 1 to be tested so as to perform various tests on the fan 1 to be tested.

[0052] The dynamic balancing test device 200 is disposed on the frame 100 , and includes a test device body, a fan installation shaft 210 , and a driving mechanism for driving the fan installation shaft 210 to rotate.

[0053] The main body of the test device is arranged at the lower side of the detection platform 130 . The main body of the test device is the main body of the existing dynamic balancing tester, and its specific structure will not be described in detail.

[0054] The fan mounting shaft 210 extends upward and is located on the detection platform 130. The fan 1 to be tested is mounted on the fan mounting shaft 210. The driving mechanism drives the fan mounting shaft 210 and the fan 1 to be tested to rotate, and the test device body can detect the dynamic balance of the fan 1 to be tested.

[0055] The weight detection device 300 is disposed on the fan mounting shaft 210 . When the fan 1 to be tested is mounted on the fan mounting shaft 210 , the weight of the fan 1 to be tested can be detected.

[0056] The vibration detection device 400 is disposed on the rack 100 and is used to detect the vibration size of the fan 1 to be tested.

[0057] Specifically, runout can be divided into end face runout and radial runout according to the different measured elements.

[0058] Therefore, the jitter detection device 400 specifically includes a first distance measuring mechanism 410 and a second distance measuring mechanism 420 .

[0059] The first distance measuring mechanism 410 is used to measure the height dimension of the blade 11 of the fan 1 to be tested after rotation, and the end face runout dimension can be obtained; the second distance measuring mechanism 420 is used to measure the diameter dimension of the blade 11 of the fan 1 to be tested after rotation, and the radial runout dimension can be obtained.

[0060] The dynamic balance test device 200, the weight detection device 300, and the runout detection device 400 are connected to the master control device 500, which can control the start and stop of the entire test system and process and store measurement data.

[0061] In some embodiments of the present application, the master control device 500 is an industrial computer.

[0062] The fan detection device of the present invention can realize the full measurement of multiple groups of data by installing the parts once, thereby improving the test efficiency and reducing the risk of damage caused by multiple installations of the fan; at the same time, it reduces the labor cost, and only one person is needed to install the parts to realize the measurement of all the data; the first distance measuring mechanism 410 and the second distance measuring mechanism 420 can realize automatic measurement of the product diameter and height data, with high measurement accuracy, avoiding the errors of manual measurement readings, and improving the accuracy of the measurement data; in addition, compared with the existing solution that can only trace the dynamic balance of the product, the present invention can save all the measured multiple groups of data in the master control device 500, realizing the full traceability of all the data.

[0063] In some embodiments of the present application, see Figure 3 The first distance measuring mechanism 410 is a measuring grating, including a first grating transmitter 411 for emitting light and a first grating receiver 412 for receiving the light emitted by the first grating transmitter 411.

[0064] The first grating transmitter 411 and the first grating receiver 412 are in the shape of long strips or long tubes.

[0065] The first grating transmitter 411 and the first grating receiver 412 are arranged vertically and correspondingly arranged on two sides of the fan 1 to be tested in the radial direction, such as the left and right sides or the front and back sides.

[0066] The first grating transmitter 411 generates a light array at a fixed interval along the length direction, and a light curtain is formed between the first grating transmitter 411 and the first grating receiver 412. The coverage surface formed by the fan 1 to be tested during the rotation process can block the light curtain formed between the first grating transmitter 411 and the first grating receiver 412. The controller can interpret the blocking amount and finally convert it into height dimension data to obtain the end face runout dimension of the fan 1 to be tested.

[0067] In some embodiments of the present application, the second distance measuring mechanism 420 is a measuring grating, including a second grating transmitter 421 for emitting light and a second grating receiver 422 for receiving light emitted by the second grating transmitter 421 .

[0068] The second grating transmitter 421 and the second grating receiver 422 are in the shape of a long strip or a long tube.

[0069] The second grating transmitter 421 and the second grating receiver 422 are arranged horizontally and correspondingly on the upper side and the lower side of the blade 11 of the fan 1 to be tested.

[0070] The second grating transmitter 421 generates a light array at a fixed interval along the length direction, and a light curtain is formed between the second grating transmitter 421 and the second grating receiver 422. The coverage surface formed by the fan 1 to be tested during the rotation process can block the light curtain formed between the second grating transmitter 421 and the second grating receiver 422. The controller can interpret the blocking amount and finally convert it into diameter size data to obtain the radial runout size of the fan 1 to be tested.

[0071] In some embodiments of the present application, the weight detection device 300 includes a weight sensor.

[0072] See also Figure 4 The fan mounting shaft 210 includes a rotating shaft 211 and a rotating shaft mounting seat 212. The rotating shaft 211 has a step portion 2111 for abutting against the fan 1 to be tested. The weight sensor is disposed on the end surface of the step portion 2111. When the fan 1 to be tested is mounted on the rotating shaft 211, it abuts against the step portion 2111, and the weight sensor can detect the weight of the fan 1 to be tested.

[0073] like Figure 7 As shown, in some embodiments of the present application, the fan detection device further includes a protective cover 700 .

[0074] The protective cover 700 is used for detection and is arranged outside the fan 1 to be tested. During the detection process, the fan blades are easy to hurt people when the fan rotates, and the protective cover 700 can play a protective role to prevent the high-speed rotating blades from hurting people.

[0075] The protective cover 700 may be made of a transparent or translucent material, so that the tester can observe the status of the fan 1 to be tested in real time during the test.

[0076] The protective cover 700 can be slidably disposed on the detection platform 130. When the protective cover 700 slides to one side, the fan 1 to be tested can be placed and installed; during testing, the protective cover 700 can be slidably disposed on the fan 1 to be tested for protection.

[0077] See also Figure 8 Two guide rails 720 are arranged on the detection platform 130 , and a plurality of sliders 710 are arranged on both sides of the bottom of the protective cover 700 . The protective cover 700 can be slidably arranged on the guide rails 720 through the sliders 710 , so that the protective cover 700 can be smoothly pushed and pulled on the detection platform 130 .

[0078] A stopper 730 may be provided at the outermost side of the detection platform 130 and at the end of the guide rail, for abutting against the protective cover 700 to limit the position and prevent the anti-slip cover from separating from the detection platform 130 .

[0079] In some embodiments of the present application, the fan detection device further includes a code scanning device 800 .

[0080] The code scanning device 800 is disposed on the rack 100 , and a label 13 is disposed on the fan 1 to be tested. The code scanning device 800 is used to identify the label 13 on the fan 1 to be tested.

[0081] The label 13 on the fan 1 to be tested may be a barcode, a QR code, an electronic tag (RFID), or the like.

[0082] Before the fan is detected, the information of the fan 1 to be detected is firstly identified and obtained by the code scanning device 800, and the information of the fan 1 to be detected is transmitted to the master control device 500 for storage.

[0083] In some embodiments, the fan detection device further includes a display device 600. The display device 600 is a display.

[0084] The display device 600 is arranged on the rack 100, and is used to display information of the fan 1 to be tested, as well as data such as the weight, runout size, and dynamic balance of the fan 1 to be tested. By setting up the display, various test data can be displayed intuitively in real time.

[0085] like Figure 7 As shown, the rack 100 has a first cabinet 110 and a second cabinet 120 that are adjacent to each other.

[0086] The upper surface of the first cabinet 110 forms a detection platform 130 . The dynamic balancing test device 200 may be disposed in the first cabinet 110 or the first cabinet may serve as a housing of the dynamic balancing test device 200 .

[0087] The second cabinet 120 is arranged on the left or right side of the first cabinet 110, and the master control device 500 and the display device 600 can be arranged in the second cabinet 120. The rack is arranged in a cabinet, and each part of the device can be arranged inside the cabinet, which plays a certain protective role.

[0088] like Fig. 9 As shown, in order to be able to adjust the levelness of the detection platform 130 and ensure the accuracy of the detection, a plurality of support feet 900 are also provided at the bottom of the frame 100. The support feet 900 have a height adjustment mechanism. The height of the support feet 900 can be adjusted through the height adjustment mechanism, thereby adjusting the height of the equipment.

[0089] Specifically, see Fig.10 The supporting foot 900 includes a base support 910, and the height adjustment mechanism includes a bolt 920 and a height adjustment nut 930 matched with the bolt 920. The base support 910 is fixed to the bottom of the bolt 920, and the bottom surface of the rack 100 is supported on the height adjustment nut 930. The height of the equipment can be adjusted by adjusting the height of the height adjustment nut 930 up and down.

[0090] In other embodiments of the present application, a level detection device may be further provided on the rack 100 to detect whether the detection platform 130 is in a level state.

[0091] In other embodiments of the present application, the fan detection equipment may also be provided with an alarm device. When performing a dynamic balance test on the product, when the dynamic balance amount does not meet the requirements or other abnormal conditions occur, an alarm message may be issued through a buzzer and an indicator light to alert the detection personnel.

[0092] In some other embodiments of the present application, a balancing weight installation slot 14 is provided on the fan hub 12 for installing a balancing weight (not shown) so as to perform a dynamic balance test by adding or removing balancing weights or replacing balancing weights of different weights.

[0093] The fan detection device of this application specifically divides the fan detection process into the following stages:

[0094] In the first stage, turn on the power switch, start the machine, and turn on the fan test equipment. At this time, all devices enter the state of waiting for detection.

[0095] In the second stage, the fan to be tested is taken, and the label 13 on the fan to be tested 1 is scanned by the code scanning device 800, so that the information of the fan to be tested 1 is transmitted to the system.

[0096] In the third stage, the protective cover 700 is opened, the fan 1 to be tested is installed on the fan mounting shaft 210, and the protective cover 700 is closed. The weight detection device 300 measures and obtains the weight data of the fan 1 to be tested; the weight data is transmitted to the display, and the weight data is automatically recorded in the system on the fan corresponding to the code scanned in the previous stage.

[0097] In the fourth stage, the test system of the dynamic balancing test device 200 is started, and the fan 1 to be tested starts to rotate. The runout detection device 400 measures the end face runout size and radial runout size of the fan; transmits the runout size data to the display, and automatically records the runout size data to the fan corresponding to the code scanned in the second stage in the system.

[0098] In the fifth stage, the dynamic balancing test device 200 obtains the dynamic balancing value of the tested fan 1. According to the actually measured dynamic balancing value, the balancing block is added or removed from the tested fan 1 until the dynamic balancing value of the product meets the requirements.

[0099] In the sixth stage, after the product measurement is finally qualified, the fan will be removed from the packaging. If the measurement fails, the product will be placed in the suspicious material area for evaluation.
