Description

Technical Field

[0001] The present application relates to the field of detection equipment, and in particular to a detection device for a crossflow fan impeller. Background Art

[0002] Crossflow fans are also called crossflow fans. During actual operation, crossflow fans can generate air flow over a large area, so they are widely used in the ventilation systems of various refrigeration equipment.

[0003] In the related technology, the crossflow fan is composed of three parts: the air duct, the impeller structure and the driving motor. At present, the impeller structure is mainly made of aluminum alloy or plastic. The impeller structure made of plastic material is composed of several impeller segments. Figure 1 The impeller segment 1 includes a connecting ring 11 and a plurality of arc-shaped blades 12 distributed around the connecting ring 11. In the actual production process, the impeller segment is injection-molded by an injection molding device, and then adjacent impeller segments are welded by an ultrasonic device to form an impeller structure.

[0004] During the manufacturing process, the impeller segments are affected by factors such as production process and improper operation, and their curved blades are prone to flash and missing parts. When welding the impeller segments using ultrasonic welding equipment, it is usually necessary to manually inspect the blade part of the impeller segments and screen out defective products in a timely manner to ensure the production quality of the subsequent impeller structure.

[0005] With regard to the above-mentioned related technologies, the detection and screening of the blade part of the impeller segment is currently mainly completed by manual visual inspection, the overall operation efficiency is low, and it is very easy to have missed detection and wrong detection. Therefore, there is room for improvement. Summary of the invention

[0006] In order to improve the detection efficiency of a crossflow fan impeller, the present application provides a crossflow fan impeller detection device.

[0007] The present application provides a crossflow fan impeller detection device, which adopts the following technical solution:

[0008] A crossflow fan impeller detection device comprises a control system, a feeding conveyor belt, a detection mechanism, a discharging conveyor belt and a grabbing mechanism;

[0009] The feeding conveyor belt is used to convey the impeller segment to be tested;

[0010] The detection mechanism comprises a detection platform, a limit block is arranged on the detection platform, the limit block is used for the impeller segment to be inserted, and the detection platform is also provided with an image acquisition component;

[0011] The discharging conveyor belt is used to convey the impeller segments that have been inspected, and the discharging conveyor belt is provided with a material removal component;

[0012] The grasping mechanism is used to grasp the impeller segment located on the feeding conveyor belt and place it into the limiting block; it is also used to grasp the impeller segment on the limiting block and place it onto the discharging conveyor belt.

[0013] The image acquisition component and the rejection component are both electrically connected to the control system. The image acquisition component is used to acquire the image of the impeller segment located on the limiting block and feed it back to the control system. The control system is used to judge whether the impeller segment is qualified according to the image fed back by the image acquisition component, and control the rejection component to remove the unqualified impeller segment from the discharging conveyor belt according to the judgment result.

[0014] By adopting the above technical solution, when detecting the impeller segment, the grasping mechanism grasps the impeller segment to be detected conveyed to the output end of the feeding conveyor belt and slews it onto the limiting block on the detection table. After the image acquisition component located on the detection table acquires the image information of the impeller segment on the limiting block at this time and feeds it back to the control system, the control system judges whether the blades of the impeller segment are qualified. Then, the grasping structure grasps the impeller segment after detection from the limiting block and places it onto the discharging conveyor belt. The qualified impeller segments are output from the output end of the discharging conveyor belt, and the unqualified impeller segments are removed from the discharging conveyor belt by the control system controlling the rejection component, realizing the automatic detection and screening of the impeller segments. Compared with the traditional method of visually inspecting the impeller segments by humans, the detection and screening efficiency of the impeller segments is effectively improved.

[0015] Preferably, the image acquisition component includes a first CCD camera, a second CCD camera and a rotation driving part; the first CCD camera is arranged facing the outer periphery of the limiting block; an installation groove is formed on the outer periphery of the limiting block, and the second CCD camera is installed in the installation groove and the second CCD camera is arranged facing the notch of the installation groove; both the first CCD camera and the second CCD camera are electrically connected to the control system; the rotation driving part is used to drive the impeller segment located on the limiting block to rotate.

[0016] By adopting the above technical solution, after the grasping mechanism slews the impeller segment to be detected onto the limiting block, the rotation driving part on the detection table drives the impeller segment slewed on the limiting block to rotate around the limiting block at this time, and the inner and outer side images of the arc-shaped blades on the impeller segment during the rotation process are acquired by the first CCD camera and the second CCD camera and fed back to the control system. The first CCD camera, the second CCD camera and the rotation driving part cooperate with each other, which is beneficial to more clearly and completely acquire the image information of several arc-shaped blades on the impeller segment to be detected.

[0017] Preferably, the rotation driving part is arranged close to the limiting block. The rotation driving part includes a support and a sliding driving part. One side of the support facing the limiting block is rotatably connected with a driving wheel. The axis direction of the driving wheel is parallel to the axis direction of the limiting block. The support is provided with a rotation driving part for driving the driving wheel to rotate; the sliding driving part is drivingly connected with the support and is used for driving the support to move towards or away from the limiting block.

[0018] By adopting the above technical solution, after the grasping mechanism sleeves the impeller segment to be detected onto the limiting block, the sliding driving part is used to drive the support to move towards the limiting block until the driving wheel on the support abuts against the outer side of the impeller segment sleeved on the limiting block at this time. Then, the rotation driving part is used to drive the driving wheel to rotate, and the impeller segment can be driven to rotate around the limiting block during the rotation of the driving wheel.

[0019] Preferably, the grasping mechanism includes a manipulator and a grasping part. The grasping part is connected to the driving end of the manipulator, and the grasping part is used to grasp and fix the impeller segment.

[0020] By adopting the above technical solution, the manipulator cooperates with the grasping part to complete the grasping and moving of the impeller segment from the feeding conveyor belt to the limiting block, and the grasping and moving from the limiting block to the discharging conveyor belt, making the movement of the impeller segment simpler and more convenient.

[0021] Preferably, the grasping part includes a support ring, and an annular limiting airbag is sleeved on the outer periphery of the support ring.

[0022] By adopting the above technical solution, considering the space limitation and the problem that when the impeller segment is clamped by a conventional clamp with relatively moving clamping parts, the arc-shaped blades of the impeller segment are easily deformed, resulting in unstable clamping; by setting a support ring and an annular limiting airbag sleeved on the outer periphery of the support ring, when grasping and moving the impeller segment, the manipulator is first used to drive the support ring to extend into the impeller segment, and then the annular limiting airbag is inflated, so that the annular limiting airbag expands and abuts against the inner sides of several arc-shaped blades of the impeller segment, realizing the grasping of the target impeller segment by the grasping part; after the impeller segment moves in place, the grasping of the impeller segment by the grasping part can be released by discharging the gas in the annular airbag. Compared with the traditional clamp, the annular limiting airbag expands and abuts against several arc-shaped blades, enabling several arc-shaped blades to be uniformly stressed at the same time, which is beneficial for the grasping part to grasp the impeller segment more firmly.

[0023] Preferably, a cleaning air knife is also supported on the inspection table, and the air outlet of the cleaning air knife faces the outer periphery of the limiting block.

[0024] By adopting the above technical solution, after the grasping mechanism sleeves the impeller segment to be detected onto the limiting block, the cleaning air knife first blows compressed air towards the impeller segment sleeved on the limiting block, and at the same time, cooperates with the rotation driving part to drive the impeller segment sleeved on the limiting block to rotate, so as to blow off the sundries adhered to the arc-shaped blades; then the first CCD camera and the second CCD camera obtain the image information of the arc-shaped blades of the impeller segment, which is beneficial to reducing the situation of misjudgment of the control system caused by the sundries on the subsequent arc-shaped blades.

[0025] Preferably, a material blocking member is also supported at the output end of the feeding conveyor belt. The material blocking member includes a material blocking air cylinder. The material blocking air cylinder is located on one side of the feeding conveyor belt, and the piston rod of the material blocking air cylinder blocks the output end of the feeding conveyor belt.

[0026] By adopting the above technical solution, through the setting of the material blocking air cylinder, the piston rod of the material blocking air cylinder is used to limit the impeller segment conveyed to the feeding conveyor belt, which is beneficial to reducing the situation that the impeller segment slides out of the feeding conveyor belt due to the influence of the conveying inertia of the feeding conveyor belt.

[0027] Preferably, the material removing assembly is located on one side of the discharging conveyor belt. The material removing assembly includes a horizontally supported material removing air cylinder. The material removing air cylinder is arranged towards the discharging conveyor belt. The piston rod of the material removing air cylinder is connected with a pushing plate, and the material removing air cylinder is electrically connected with the control system.

[0028] By adopting the above technical solution, when the discharging conveyor belt conveys the unqualified impeller segment to be opposite to the pushing plate, the material removing air cylinder is used to drive the pushing plate to move towards the direction close to the discharging conveyor belt, so as to push the unqualified impeller segment off the discharging conveyor belt, realizing the removal of the unqualified impeller segment.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. When detecting the impeller segment, the grasping mechanism grabs the impeller segment to be detected from the feeding conveyor belt and moves it onto the limiting block on the detection table. After the image acquisition component on the detection table obtains the image information of the impeller segment and feeds it back to the control system, the grasping mechanism grabs the detected impeller segment from the limiting block and moves it onto the discharging conveyor belt. The qualified impeller segments are output from the output end of the discharging conveyor belt, and the unqualified impeller segments are removed from the discharging conveyor belt by the control system controlling the material removing mechanism, realizing the automatic detection and screening of the impeller segments, which is beneficial to improving the detection and screening efficiency of the impeller segments.

[0031] 2. When grasping the moving impeller segment through the grasping structure, after the driving end support ring of the manipulator is driven to enter the inner circumference of the target impeller segment, the annular limiting airbag on the outer circumference of the support ring is inflated, so that the annular limiting airbag expands and abuts against the inner sides of several arc-shaped blades of the impeller segment, realizing the stable grasping of the impeller segment.

[0032] 3. By arranging a cleaning air knife on the detection table and making the cleaning air knife face the outer circumference of the limiting block, and then when the impeller segment to be detected is sleeved on the limiting block through the grasping mechanism, the impeller segment driven by the rotation driving part first rotates around the limiting block, and the cleaning air knife is coordinated to blow compressed air towards the impeller segment sleeved on the limiting block to remove the sundries adhered to the arc-shaped blades of the impeller segment to be detected, reducing the situation that the sundries affect the judgment of the subsequent control system.

[0043] The following will further describe this application in detail with reference to the attached Figure 1-8 drawings.

[0044] Referring to Figure 1 FIGs.

[0045] An impeller detection device for a cross-flow fan is disclosed in an embodiment of this application. Referring to Figure 2 and Figure 3 FIGs., it includes a control system, a feeding conveyor belt 2, a detection mechanism 3, a discharge conveyor belt 4, and a gripping mechanism 5. The feeding conveyor belt 2 is used to convey the impeller segment 1 to be detected; the detection mechanism 3 includes a detection table 31, on which a limit block 32 and an image acquisition component are arranged. The limit block 32 is used for the impeller segment 1 to be sleeved, and the image acquisition component is arranged close to the limit block 32. The discharge conveyor belt 4 is used to convey the detected impeller segment 1, and a rejecting component 41 is arranged on the discharge conveyor belt 4. The gripping mechanism 5 is arranged close to the feeding conveyor belt 2, the detection mechanism 3, and the discharge conveyor belt 4, and is used to grip the impeller segment 1 to be detected on the feeding conveyor belt 2 and sleeve it onto the limit block 32, and is also used to grip the detected impeller segment 1 on the limit block 32 and place it into the discharge conveyor belt 4.

[0046] Both the image acquisition component and the rejecting component 41 are electrically connected to the control system. The image acquisition component is used to acquire the image information of the impeller segment 1 sleeved on the limit block 32 and feedback it to the control system. The control system is used to judge whether the arc-shaped blade 12 of the liquid-cooled segment is qualified according to the image information fed back by the image acquisition component, and control the rejecting component 41 to remove the unqualified impeller segment 1 from the discharge conveyor belt 4 according to the judgment result; it is a prior art for the control system to judge whether the product is qualified by feeding back the image information, and details are not described here.

[0047] Referring to Figure 3 andFigure 4 , the detection platform 31 is located between the output end of the feeding conveyor belt 2 and the input end of the discharging conveyor belt 4. A material blocking member is provided on the side of the detection platform 31 close to the feeding conveyor belt 2, and the material blocking member is provided close to the output end of the feeding conveyor belt 2. The material blocking member includes a horizontally arranged material blocking cylinder 21, and the material blocking cylinder 21 is connected to the detection platform 31 through a bracket. The material blocking cylinder 21 is located on one side of the output end of the feeding conveyor belt 2 and is arranged vertically with the feeding conveyor belt 2, and the piston rod of the material blocking cylinder 21 is arranged to block the output end of the feeding conveyor belt 2. Through the setting of the material blocking cylinder 21, the piston rod of the material blocking cylinder 21 can be used to limit the impeller segment 1 transmitted to the feeding conveyor belt 2, so as to prevent the impeller segment 1 from sliding out of the feeding conveyor belt 2 due to the inertia of movement.

[0048] The bottom end of the limit block 32 is coaxially connected with an annular connecting plate 320, and the annular connecting plate 320 is fixed on the detection platform 31 by a plurality of countersunk bolts. The top edge of the limit block 32 is chamfered to facilitate the subsequent impeller segment 1 to be more easily inserted.

[0049] The image acquisition component includes a first CCD camera 33, a second CCD camera 34 and a rotation drive unit 35. The first CCD camera 33 is supported on the detection platform 31 by a bracket and the first CCD camera 33 is arranged toward the limit block 32; the outer periphery of the limit block 32 is provided with a mounting groove 321 corresponding to the second CCD camera 34. The second CCD camera 34 is supported in the mounting groove 321 by a bracket and the second CCD camera 34 is arranged toward the notch of the mounting groove 321. The first CCD camera 33 and the second CCD camera 34 are staggered, and both the first CCD camera 33 and the second CCD camera 34 are electrically connected to the control system.

[0050] The rotation driving part 35 is arranged near the limit block 32, and is used to drive the impeller segment 1 sleeved on the limit block 32 to rotate. The rotation driving part 35 includes a support 351 and a sliding driving member. The support 351 is vertically rotatably connected to a driving wheel 353 on one side facing the limit seat, and the axis direction of the driving wheel 353 is arranged parallel to the axis direction of the limit block 32. The outer periphery of the driving wheel 353 is wrapped with a flexible rubber layer. The support 351 is also provided with a rotary driving member, specifically, the rotary driving member is a reduction motor 354, and the output end of the reduction motor 354 is coaxially connected to the driving wheel 353, and is used to drive the driving wheel 353 to rotate. The sliding drive component includes a sliding cylinder 352, which is supported on the detection table 31 through a bracket. The sliding cylinder 352 is located on the side of the support 351 away from the limit block 32, and the piston rod of the sliding cylinder 352 is connected to the support 351. Subsequently, the sliding cylinder 352 can drive the support 351 to drive the driving wheel 353 to move toward or away from the limit block 32.

[0051] Obtain the settings of the component through the image. Subsequently, when obtaining the image information of the impeller segment 1 on the limit block 32 through the image, the sliding cylinder 352 drives the support 351 to drive the driving wheel 353 to move towards the direction close to the limit block 32 until the driving wheel 353 abuts against the outer side of the impeller segment 1 sleeved on the outer periphery of the limit block 32. The driving wheel 353 is driven to rotate by the reduction motor 354, and the rotating driving wheel 353 drives the impeller segment 1 to rotate. During this period, the first CCD camera 33 and the second CCD respectively continuously capture and obtain the inner and outer side images of the arc-shaped blades 12 at various positions on the impeller segment 1 and feedback them to the control system for the control system to judge whether the arc-shaped blades 12 on the impeller segment 1 are qualified according to the feedback images.

[0052] An auxiliary lighting fixture 311 is also erected above the limit block 32, and the auxiliary lighting fixture 311 is connected to the inspection table 31 through a bracket. The auxiliary lighting fixture 311 is used to illuminate the area of the limit block 32 so that the first CCD camera 33 and the second CCD camera 34 can more clearly obtain the image information of the impeller segment 1 subsequently.

[0053] Refer to Figure 3 And Figure 4 Refer to

[0054] Refer to Figure 2 And Figure 5, The material removal component 41 is located on one side of the discharge conveyor belt 4. The material removal component 41 includes a material removal cylinder 411. The material removal cylinder 411 is horizontally supported outside the discharge conveyor belt 4 through a bracket. The material removal cylinder 411 is arranged towards the discharge conveyor belt 4 and is higher than the discharge conveyor belt 4. The piston rod of the material removal cylinder is connected with a pushing plate 412; the material removal cylinder 411 is electrically connected to the control system. Subsequently, when the discharge conveyor belt 4 conveys the unqualified impeller segment 1 to be opposite to the pushing plate 412, the control system controls the material removal cylinder 411 to drive the pushing plate 412 to move in the direction close to the discharge conveyor belt 4, so as to use the pushing plate 412 to push the unqualified impeller segment 1 out of the discharge conveyor belt 4, realizing the removal of the unqualified impeller segment 1. There is a gap between the bottom of the pushing plate 412 and the conveying surface of the discharge conveyor belt 4, which is beneficial to restricting the interference between the pushing plate 412 and the discharge conveyor belt 4 during the subsequent movement of the pushing plate 412.

[0055] A qualified product collection box 42 is placed below the output end of the discharge conveyor belt 4. After the subsequently detected qualified impeller segments 1 are output from the output end of the discharge conveyor belt 4, they can fall into the qualified product collection box 42, realizing the collection of the qualified impeller segments 1. A defective product collection box 43 is placed below the outer side of the discharge conveyor belt 4 opposite to the material lifting component. The unqualified impeller segments 1 pushed out by the pushing plate 412 subsequently can fall into the defective product collection box 43, realizing the collection of the unqualified impeller segments 1.

[0056] Refer to Figure 6 And Figure 7 , The grasping mechanism 5 includes a manipulator 51 and a grasping part 52. The grasping part 52 is connected to the driving end of the manipulator 51 and is used for grasping the impeller segment 1. In this embodiment, the manipulator 51 is specifically a five-axis manipulator 51. The grasping part 52 includes a support ring 521. The support ring 521 is coaxially connected with a support rod 523. One end of the support rod 523 far from the support ring 521 is coaxially connected with a flange 524. The flange 524 is connected to the driving end of the manipulator 51 through bolts. An annular limiting airbag 522 is sleeved on the outer periphery of the support ring 521. An annular limiting groove 5211 is circumferentially formed on the outer periphery of the support ring 521 corresponding to the annular limiting airbag 522. The inner periphery of the annular limiting airbag 522 is embedded in the annular limiting groove 5211, realizing the stable installation of the annular limiting airbag 522 on the outer periphery of the support ring 521.

[0057] Refer to Figure 7 And Figure 8, when the impeller segment 1 is grasped by the grasping mechanism 5, after the support ring 521 is driven by the manipulator 51 to enter the inner circumference of the target impeller segment 1, the annular limiting airbag 522 is inflated, so that the annular limiting airbag 522 expands and abuts against the inner sides of several arc-shaped blades 12 of the impeller segment 1. Compared with the traditional fixture that clamps an object by relatively moving clamping parts, the grasping part 52 can firmly grasp the impeller segment 1 on the inner circumference of the impeller segment 1, effectively reducing the situation where the movement of the grasping part 52 is restricted due to space limitations; at the same time, the inflated annular limiting airbag 522 is used to abut against the outer circumference of several arc-shaped blades 12 to firmly grasp the impeller segment 1, which is beneficial to reducing the situation where the arc-shaped blades 12 being clamped are locally deformed due to force when the traditional fixture clamps the impeller segment 1 by relatively moving clamping parts, resulting in unstable clamping of the impeller segment 1. When the grasping of the impeller segment 1 by the grasping mechanism 5 is released, the gas in the annular limiting airbag 522 is released, and the grasping of the impeller segment 1 can be released.

[0058] The implementation principle of the embodiment of the present application is as follows: the arc-shaped blades 12 of the impeller segment 1 to be detected are placed upward at the input end of the feeding conveyor belt 2, and after the feeding conveyor belt 2 conveys the impeller segment 1 to be detected to the output end, it is grasped by the grasping mechanism 5 and sleeved on the limiting block 32 of the detection table 31, and then the grasping mechanism 5 releases the grasping of the impeller segment 1 and moves away from the impeller segment 1.

[0059] The compressed air is blown towards the impeller segment 1 on the limiting table by the cleaning air knife 36 on the detection table 31, and at the same time, the impeller segment 1 on the limiting block 32 is driven to rotate by the rotation driving part 35 to realize the cleaning of the impeller segment 1.

[0060] After the cleaning is completed, the cleaning air knife 36 stops blowing compressed air, and the rotation driving part 35 continues to drive the impeller segment 1 to rotate. During this period, the first CCD camera 33 and the second CCD camera 34 respectively continuously acquire the image information of the arc-shaped blades 12 on the impeller segment 1 and immediately feedback it to the control system, and the control system judges whether the arc-shaped blades 12 of the detected impeller segment 1 are qualified according to the feedback image information.

[0061] The detected impeller segment 1 is transferred from the limiting block 32 to the discharging conveyor belt 4 by the grasping mechanism 5. The qualified impeller segments 1 are transmitted out from the output end of the discharging conveyor belt 4 and fall into the qualified product collection box 42. When the unqualified impeller segments 1 are conveyed to the rejection component 41 by the discharging conveyor belt 4, the control system controls the rejection air cylinder 411 to drive the pushing plate 412 to push it down into the defective product collection box 43.

[0062] The present application can realize the automatic detection and screening of the impeller segments 1 of the cross-flow fan, effectively improving the detection and screening efficiency of the impeller segments 1.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
