[0001] The present invention relates to the technical field of fan detection, and in particular to an appearance detection device for a high-speed fan. Background Art

[0002] A fan is a type of driven fluid machine that relies on input mechanical energy to increase gas pressure and deliver the gas. The term "fan" is a commonly used abbreviation in China for gas compression and gas delivery machinery. Commonly referred to as fans include ventilators, blowers, and wind turbine drive motors. High-speed fans are characterized by high speeds and large air volumes. With the continuous development of the times, high-speed fans are widely used in various fields. The fan impeller is subjected to large centrifugal forces during high-speed rotation. If the surface is damaged or defective, it is easily damaged during high-speed rotation, thus damaging the high-speed fan.

[0003] The existing fan appearance detection device detects both the front and back sides of the fan, ignoring the appearance of the side of the fan impeller, which can easily lead to the neglect of side damage and depression. The incomplete detection will affect the safety of the product, and it is inconvenient to mark the damaged points during inspection, which is not conducive to subsequent maintenance. In response to the above situation, we have launched an appearance detection device for high-speed fans.

The lifting assembly is convenient for driving the fan impeller to rise and fall for testing, and the testing assembly is convenient for performing shape testing on the surface of the fan impeller;

[0009] A driving motor is fixedly mounted in the middle of the upper end of the base, and a flip assembly is fixedly mounted on the output end of the driving motor, and the flip assembly facilitates driving the fan impeller to flip for appearance inspection;

[0010] An auxiliary detection device for detecting the side surface of the fan impeller is fixedly installed in the middle of the lower end of the top plate.

[0011] By providing a lifting component to drive the fan impeller to rise and fall, it is convenient to perform appearance inspection on the fan impeller. After the lifting component drives the fan impeller to rise, the detection component runs to detect the appearance of the fan impeller. After detecting that the appearance is damaged, the inkjet component on the detection component performs inkjet treatment on the damaged appearance, which is convenient for subsequent repair of the fan impeller.

The fan impeller is driven to rotate by the rotating structure on the flipping component to realize the appearance inspection of the side of the fan impeller, which is convenient for detailed inspection of the fan impeller and improves the inspection quality. After the side appearance inspection is completed, the flipping component is rotated to the other side to perform appearance inspection on the remaining side of the fan impeller, so as to realize comprehensive inspection of the fan impeller and reduce the chance of outflow of defective products in appearance.

[0012] In a preferred solution, the detection component includes a slide groove opened on the front and rear sides of the upper end of the top plate, the slide groove is rotatably connected to the first screw rod, the outer side of the first screw rod is threadedly connected to the slide, a telescopic rod is provided on the left side of the lower end of the slide, a scanner is provided on the right side of the lower end of the slide, the lower end of the telescopic rod is fixedly installed with a fixed platform, the lower end of the fixed platform is slidably connected to a hollow pipe rack, the lower end of the hollow pipe rack is fixedly installed with a push rod, the fixed platform is provided with a first ink bag inside, the upper end of the hollow pipe rack is fixedly installed with a push plate, and the hollow pipe rack passes through the push plate and is connected with the first ink bag.

When external damage is detected, the telescopic rod drives the fixed platform downward, causing the push rod to contact the damaged surface. The downward pressure of the telescopic rod and the contact of the push rod with the fan impeller generate a reaction force, causing the hollow pipe rack to push the push plate back into the fixed platform, thereby squeezing the first ink pack and spraying ink around the damaged area on the fan impeller surface. This facilitates subsequent staff to observe the external damage and facilitate repairs of the damaged fan impeller.

At the same time, the groove in the placement table cooperates with the internal spring to drive the slider to slide closer to the central axis, so that the clamping block firmly clamps the fan impeller. When the placement table slides down and the lower clamping plate rotates to just below the placement table, the slider contacts the lower clamping plate and retracts due to the sliding of the placement table.

[0017] The fan impeller is clamped by providing a lower clamping plate and an upper clamping plate, which makes it convenient to drive the fan impeller to rotate for a comprehensive appearance scan. After the fan impeller is clamped by the upper and lower clamping plates, the double-headed screw on the upper clamping plate rotates, driving the clamping block to slide to both sides and against the inner wall of one side of the fan impeller opening. The rubber pad improves the tightness of the clamping and prevents the clamping block from causing damage to the fan impeller. The motor in the upper clamping plate drives the disc to rotate, and the fan impeller clamped by the clamping block also rotates accordingly, which is convenient for the appearance inspection of the side of the fan impeller.

[0035] 1 and 5 , a device for detecting the appearance of a high-speed fan includes a base 1 , a top plate 2 is fixedly mounted on the upper end of the base 1 , and a detection assembly 3 is fixedly mounted on the top plate 2 ;

[0036] A lifting assembly 4 is fixedly installed at the front and rear ends of the upper end of the base 1. A fan impeller 7 is provided on the upper end of the lifting assembly 4. The lifting assembly 4 is convenient for driving the fan impeller 7 to rise and fall for inspection. The inspection assembly 3 is convenient for inspecting the surface of the fan impeller 7.

[0037] A driving motor 5 is fixedly mounted in the middle of the upper end of the base 1, and a flip assembly 6 is fixedly mounted on the output end of the driving motor 5. The flip assembly 6 facilitates the fan impeller 7 to flip for appearance inspection;

[0038] An auxiliary detection device 8 for detecting the side surface of the fan impeller 7 is fixedly installed in the middle of the lower end of the top plate 2.

[0039] In this embodiment: the fan impeller 7 is driven to rise by the lifting component 4, so as to facilitate the appearance inspection of the fan blade surface through the detection component 3. After the one-side inspection is completed, the fan impeller 7 is driven to descend by the lifting component 4, and the fan impeller 7 is brought into contact with the flip component 6. The fan impeller 7 is then rotated to the bottom of the auxiliary detection device 8 by the flip component 6, and the appearance inspection of the side of the fan impeller 7 is performed by the auxiliary detection device 8. After the side inspection of the fan impeller 7 is completed, the fan impeller 7 is driven to flip to the lifting component 4 on the other side by the flip component 6, and the appearance inspection is performed on the remaining side, so as to facilitate the comprehensive inspection of the fan impeller 7 and reduce the chance of defective products flowing out.

[0040] In the above technical solution, in order to reduce the loss of human resources, it is necessary to automatically perform an appearance inspection on the fan impeller 7. The specific operation is as follows:

[0041] 1 , 2 and 3 , in a preferred embodiment, the detection assembly 3 includes a slide groove 31 opened on the front and rear sides of the upper end of the top plate 2, a first screw rod 32 is rotatably connected to the inside of the slide groove 31, a slide 33 is threadedly connected to the outer side of the first screw rod 32, a telescopic rod 34 is provided on the left side of the lower end of the slide 33, a scanner 310 (model: SIMSCAN 42) is provided on the right side of the lower end of the slide 33, a fixed platform 35 is fixedly installed at the lower end of the telescopic rod 34, a hollow pipe rack 36 is slidably connected to the lower end of the fixed platform 35, a push plate 37 is fixedly installed at the lower end of the hollow pipe rack 36, a first ink bag 38 is provided inside the fixed platform 35, a push plate 39 is fixedly installed on the upper end of the hollow pipe rack 36, and the hollow pipe rack 36 passes through the push plate 39 and is connected to the first ink bag 38.

[0042] When the scanner 310 detects any damage to the appearance of the fan impeller 7, the telescopic rod 34 extends and drives the fixed platform 35 to press down, so that the push rod 37 contacts the damaged surface of the fan impeller 7. Due to the downward pressure of the telescopic rod 34 and the contact of the push rod 37 with the fan impeller 7, a reaction force is generated, so that the hollow pipe rack 36 drives the push plate 39 to push back into the fixed platform 35, so that the push plate 39 squeezes the first ink bag 38, so that the ink in the first ink bag 38 is sprayed out through the hollow pipe rack 36, and ink is sprayed on the damaged surface of the fan impeller 7, which is convenient for subsequent staff to observe the damaged appearance and to repair the damaged part of the fan impeller 7.

[0043] In the above technical solution, in order to facilitate the lifting of the fan impeller 7 and prevent the fan impeller 7 from shaking and causing dislocation, the specific operations are as follows:

[0044] 1 and 4 , in a preferred embodiment, the lifting assembly 4 includes a second screw rod 41 rotatably connected to the front and rear sides of the upper end of the base 1, the outer side of the second screw rod 41 is threadedly connected to a placement platform 42, a groove 43 is provided inside the placement platform 42, and a slider 44 is slidably connected to the side of the groove 43 close to the central axis, a spring 45 is provided between the slider 44 and the groove 43, and a clamping block 46 is fixedly installed on the upper end of the slider 44.

[0045] When the lifting plate 42 is lifted, the slider 44 is in the position where the fan impeller 7 is moved upwards and downwards, thereby releasing the fan impeller 7 from the position where the fan impeller 7 is moved upwards and downwards, thereby releasing the fan impeller 7 from the position where the fan impeller 7 is moved upwards and downwards, thereby releasing the fan impeller 7 from the position where the fan impeller 7 is moved upwards and downwards, thereby releasing the fan impeller 7 from the position where the fan impeller 7 is moved upwards and downwards, thereby releasing the fan impeller 7 from the position where the fan impeller 7 is moved upwards and downwards, thereby releasing the fan impeller 7 from the position where the fan impeller 7 is moved upwards and downwards, thereby releasing the fan impeller 7 from the position where the fan impeller 7 is moved upwards and downwards,

[0046] In the above technical solution, in order to facilitate the flipping of the fan impeller 7 and to rotate the fan impeller 7 so that the auxiliary detection device 8 can detect the appearance, the specific operations are as follows:

[0047] 5 and 6, in a preferred embodiment, the flip assembly 6 includes a lower clamping plate 61 fixedly mounted on the output end of the drive motor 5, the left side of the lower clamping plate 61 is rotatably connected to the upper clamping plate 62, the upper end of the lower clamping plate 61 is rotatably connected to the turntable 63, the lower end of the lower clamping plate 61 is rotatably connected to the disc 64, and the lower end of the disc 64 is provided with an empty slot 65, the inside of the empty slot 65 is rotatably connected to a double-headed screw rod 66, the outer side of the double-headed screw rod 66 is threadedly connected to a clamping block 67, and a rubber pad 68 is bonded to the side of the clamping block 67 away from the central axis.

[0048] In this embodiment, the fan impeller 7 is clamped by the lower clamping plate 61 and the upper clamping plate 62, so as to drive the fan impeller 7 to rotate and perform a full-face appearance scan. After the fan impeller 7 is clamped by the upper clamping plate 62 and the lower clamping plate 61, the double-headed screw 66 on the disc 64 connected to the upper clamping plate 62 is started, and the rotation of the double-headed screw 66 drives the clamping block 67 to slide in the empty slot 65, so that the clamping block 67 slides to both sides in the empty slot 65 and presses against the fan impeller 7 to open. The inner wall on one side of the opening, and the rubber pad 68 will increase the tightness of the clamping block 67 and the fan impeller 7, and can also prevent the clamping block 67 from causing damage to the fan impeller 7. The motor in the upper splint 62 drives the disc 64 to rotate, and the fan impeller 7 clamped by the clamping block 67 also rotates accordingly, which is convenient for the appearance inspection of the other side of the fan impeller 7. The turntable 63 on the lower splint 61 will also rotate with the rotation of the fan impeller 7, thereby improving the smoothness of the rotation of the fan impeller 7.

[0049] In the above technical solution, in order to inspect the side of the fan impeller 7 and reduce the outflow of defective fan impellers 7, the specific operations are as follows:

[0050] 7 and 8 , in a preferred embodiment, the auxiliary detection device 8 includes a card slot 81 provided at the lower end of the top plate 2, a third screw rod 82 is rotatably connected inside the card slot 81, and an auxiliary platform 84 is threadedly connected to the outer side of the third screw rod 82. A limiting groove 83 is provided at the front and rear ends of the lower end of the top plate 2 at the card slot 81, an auxiliary scanner 85 is provided on the left side of the lower end of the auxiliary platform 84, and the inkjet assembly includes a hydraulic rod 86 provided on the right side of the lower end of the auxiliary platform 84, a fixed column 87 is provided at the lower end of the hydraulic rod 86, a second ink bag 88 is provided inside the fixed column 87, an inkjet tube rack 89 is fixedly installed at the lower end of the fixed column 87, and a fixed rod 810 is fixedly installed at the lower end of the inkjet tube rack 89.

[0051] In this embodiment, the third screw rod 82 in the card slot 81 is started, and the auxiliary platform 84 is driven to slide in the card slot 81 by the third screw rod 82. At the same time, the auxiliary platform 84 also slides in the limit groove 83. The setting of the limit groove 83 improves the stability of the auxiliary platform 84 when sliding. When the flip assembly 6 drives the fan impeller 7 to rotate to the bottom of the auxiliary detection device 8, the third screw rod 82 drives the auxiliary platform 84 to slide and cooperates with the flip assembly 6 to drive the fan impeller 7 to rotate, and a full-scale scanning and detection of the side of the fan impeller 7 is performed. When the auxiliary scanner 85 (model: SIMSCAN 42) scans that the fan impeller 7 has external damage, the hydraulic rod 86 drives the fixed column 87 to slide down, and the fixed rod 810 contacts the damaged part, so that the inkjet tube rack 89 squeezes the second ink bag 88 in the fixed column 87, and ink is sprayed around the damaged part, which is convenient for subsequent maintenance of the fan impeller 7.

[0052] Working principle: When in use, first place the fan impeller 7 on the placement platform 42, and start the second screw rod 41 through the motor to rotate the second screw rod 41 to drive the placement platform 42 to move up and down. The lifting of the placement platform 42 will drive the fan impeller 7 to move up and down, and drive the fan impeller 7 to rise close to the appearance detection component 3. At the same time, the groove 43 in the placement platform 42 cooperates with the spring 45 inside the groove 43 to drive the slider 44 to slide to the side close to the central axis, so that the clamping block 46 firmly clamps the fan impeller 7, thereby improving the stability of the fan impeller 7 when it is lifted and lowered, and improving the stability of the fan impeller 7 during detection, and then start the first screw rod 32 in the slide groove 31, so that the first screw rod 32 drives the slide 33 to slide in the slide groove 31, and the lower end of the slide 33 The scanner 310 will also slide along, thereby driving the scanner 310 to scan and detect the surface of the fan impeller 7. When the scanner 310 detects any damage to the appearance of the fan impeller 7, the telescopic rod 34 extends to drive the fixed platform 35 to press down, so that the push rod 37 contacts the damaged surface of the fan impeller 7. Due to the downward pressure of the telescopic rod 34 and the contact of the push rod 37 with the fan impeller 7, a reaction force is generated, causing the hollow pipe rack 36 to drive the push plate 39 to push back into the fixed platform 35, so that the push plate 39 squeezes the first ink bag 38, so that the ink in the first ink bag 38 is sprayed out through the hollow pipe rack 36, and ink is sprayed on the damaged surface of the fan impeller 7, so that subsequent staff can observe the damaged appearance and repair the damaged part of the fan impeller 7.

[0053] Subsequently, after the inspection of one side of the fan impeller 7 is completed, the second screw 41 is started by the motor to drive the placement table 42 to slide down, and the lower clamping plate 61 is rotated to the bottom of the placement table 42. Due to the sliding of the placement table 42, the slider 44 contacts the lower clamping plate 61, and the placement table 42 slides down so that the slider 44 at the front end of the inverted platform type contacts the lower clamping plate 61 and retracts under the force, and drives the spring 45 to retract and the clamping block 46 to slide to both sides, so that the clamping block 46 releases the limit on the fan impeller 7, making it easier for the flipping component 6 to drive the fan impeller 7 to flip.

[0054] Then the upper clamping plate 62 is rotated to the upper end of the fan impeller 7, and the fan impeller 7 is clamped by the lower clamping plate 61 and the upper clamping plate 62, so as to drive the fan impeller 7 to rotate for a comprehensive appearance scan. After the fan impeller 7 is clamped by the upper clamping plate 62 and the lower clamping plate 61, the flip assembly 6 is driven by the driving motor 5 to rotate to the lower end of the auxiliary detection device 8, and then the double-headed screw rod 66 on the disc 64 connected to the upper clamping plate 62 is started. The rotation of the double-headed screw rod 66 drives the clamping block 67 to slide in the empty slot 65, so that the clamping block 67 slides to both sides in the empty slot 65 and presses against the inner wall of the opening side of the fan impeller 7. At the same time, the rubber pad 68 will increase the tightness of the clamping block 67 and the fan impeller 7, and can also prevent The stopping clamping block 67 causes damage to the fan impeller 7. The motor in the upper splint 62 drives the disc 64 to rotate, and the fan impeller 7 clamped by the clamping block 67 also rotates accordingly. The turntable 63 on the lower splint 61 also rotates along with the rotation of the fan impeller 7, thereby improving the smoothness of the rotation of the fan impeller 7. Then the third screw rod 82 in the slot 81 is started by the motor, and the auxiliary platform 84 is driven to slide in the slot 81 by the third screw rod 82. At the same time, the auxiliary platform 84 also slides in the limiting groove 83. The setting of the limiting groove 83 improves the stability of the auxiliary platform 84 when sliding. The auxiliary platform 84 is driven to slide by the third screw rod 82 and cooperates with the flip assembly 6 to drive the fan impeller 7 to rotate, and the side of the fan impeller 7 is scanned and detected.

[0055] When the fan impeller 7 is scanned to have external damage, the hydraulic rod 86 drives the fixed column 87 to slide down, and the fixed rod 810 contacts the damaged part, so that the inkjet tube rack 89 squeezes the second ink bag 88 in the fixed column 87, and ink is sprayed around the damaged part, which is convenient for the subsequent maintenance of the fan impeller 7. After the side scan of the fan impeller 7 is completed, the flip component 6 is started again to drive the fan impeller 7 to rotate to the lifting component 4 on the other side, so as to facilitate the inspection of the other side that has not been inspected, thereby improving the comprehensiveness of the appearance inspection of the fan impeller 7 and reducing the chance of defective fan impeller 7 flowing out.
