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: 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; The feeding conveyor belt is used to convey the impeller segment to be tested; 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; 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; The grabbing mechanism is used to grab the impeller segment on the feeding conveyor belt and put it into the limiting block; it is also used to grab the impeller segment on the limiting block and put it into the discharging conveyor belt; The image acquisition component and the material removal 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 limit block and feed it back to the control system. The control system is used to judge whether the impeller segment is qualified based on the image feedback from the image acquisition component, and control the material removal component to remove the unqualified impeller segment from the discharge conveyor belt based on the judgment result.

[0008] By adopting the above technical scheme, when inspecting the impeller segment, the grabbing mechanism grabs the impeller segment to be inspected that is transported to the output end of the feeding conveyor belt and inserts it into the limit block on the inspection table. The image information of the impeller segment on the limit block at this time is obtained by the image acquisition component located on the inspection table and then fed back to the control system. The control system determines whether the impeller segment blades are qualified. Thereafter, the grabbing structure grabs the inspected impeller segment from the limit block and puts it onto the discharging conveyor belt. The qualified impeller segment is transmitted through the output end of the discharging conveyor belt, and the unqualified impeller segment is removed from the discharging conveyor belt by the control system controlling the rejecting component, thereby realizing automatic inspection and screening of the impeller segment. Compared with the traditional method of manually visually inspecting the impeller segment, the inspection and screening efficiency of the impeller segment is effectively improved.

[0009] Preferably, the image acquisition component includes a first CCD camera, a second CCD camera and a rotation drive unit; the first CCD camera is arranged toward the outer periphery of the limit block; a mounting groove is opened on the outer periphery of the limit block, the second CCD camera is installed in the mounting groove and the second CCD camera is arranged toward the notch of the mounting groove; both the first CCD camera and the second CCD camera are electrically connected to the control system; the rotation drive unit is used to drive the impeller segment located on the limit block to rotate.

[0010] By adopting the above technical solution, after the grasping mechanism inserts the impeller segment to be inspected into the limit block, the rotating drive unit on the inspection platform drives the impeller segment mounted on the limit block to rotate around the limit block, and the first CCD camera and the second CCD camera are used to obtain the inner and outer side images of the arc blades on the impeller segment during the rotation process and feed them back to the control system. The first CCD camera, the second CCD camera and the rotating drive unit cooperate with each other, which is conducive to more clean and complete acquisition of image information of several arc blades on the impeller segment to be inspected.

[0011] Preferably, the rotation driving part is arranged close to the limit block, and the rotation driving part includes a support and a sliding driving member. The support is rotatably connected to a driving wheel on one side toward the limit block, and the rotation axis direction of the driving wheel is arranged parallel to the axis direction of the limit block. The support is provided with a rotation driving member for driving the driving wheel to rotate; the sliding driving member is drivingly connected to the support, and is used to drive the support to move toward or away from the limit block.

[0012] By adopting the above technical solution, after the grasping mechanism inserts the impeller segment to be detected onto the limit block, the sliding drive component drives the support to move toward the limit block until the driving wheel on the support abuts against the outer side of the impeller segment mounted on the limit block, and then the driving wheel is driven to rotate by the rotary drive component. During the rotation of the driving wheel, the impeller segment can be driven to rotate around the limit block.

[0013] Preferably, the grasping mechanism comprises a manipulator and a grasping portion, wherein the grasping portion is connected to a driving end of the manipulator, and the grasping portion is used to grasp and fix the impeller segment.

[0014] By adopting the above technical solution, the impeller segment is grabbed and moved from the feeding conveyor belt to the limit block, and from the limit block to the discharge conveyor belt by the robot arm cooperating with the grabbing part, making the movement of the impeller segment simpler and more convenient.

[0015] Preferably, the grasping portion comprises a support ring, and an annular limiting airbag is sleeved on the outer periphery of the support ring.

[0016] By adopting the above technical solution, considering the space limitation and the problem that the arc blades of the impeller segment are easily deformed when the ordinary conventional clamp clamps the impeller segment through the relatively moving clamping part, resulting in unstable clamping; by setting a support ring and an annular limiting airbag sleeved on the outer circumference of the support ring, when grabbing and moving the impeller segment, the manipulator first drives the support ring to extend into the impeller segment, and then inflates the annular limiting airbag to expand and press against the inner side of several arc blades of the impeller segment, so that the grasping part can grasp the target impeller segment; after the impeller segment is moved into place, the gas in the annular airbag is released to release the grasping part of the impeller segment. Compared with the traditional clamp, the use of the annular limiting airbag to expand and press against several arc blades can achieve uniform force on several arc blades at the same time, which is conducive to the grasping part to grasp the impeller segment more firmly.

[0017] Preferably, a cleaning air knife is also supported on the detection table, and the air outlet of the cleaning air knife is arranged toward the outer periphery of the limiting block.

[0018] By adopting the above technical solution, after the grabbing mechanism inserts the impeller segment to be inspected into the limit block, the cleaning air knife first blows compressed air toward the impeller segment mounted on the limit block, and at the same time cooperates with the rotation drive part to drive the impeller segment mounted on the limit block to rotate, so as to blow away the debris adhering to the curved blades; then the first CCD camera and the second CCD camera obtain the image information of the curved blades of the impeller segment, which is helpful to reduce the situation where the control system misjudges due to the debris on the subsequent curved blades.

[0019] Preferably, a material blocking member is also supported at the output end of the feeding conveyor belt, and the material blocking member includes a material blocking cylinder, the material blocking cylinder is located at one side of the feeding conveyor belt, and the piston rod of the material blocking cylinder blocks the output end of the feeding conveyor belt.

[0020] By adopting the above technical solution and setting a material-blocking cylinder, the impeller segment transmitted to the feeding conveyor belt is limited by the piston rod of the material-blocking cylinder, which helps to reduce the situation where the impeller segment is affected by the conveying inertia of the feeding conveyor belt and slips out of the feeding conveyor belt.

[0021] Preferably, the material-picking component is located on one side of the discharging conveyor belt, and the material-picking component includes a horizontally supported material-picking cylinder, the material-picking cylinder is arranged toward the discharging conveyor belt, the piston rod of the material-picking cylinder is connected to a push plate, and the material-picking cylinder is electrically connected to the control system.

[0022] By adopting the above technical solution, when the unqualified impeller segment is transported by the discharge conveyor belt to the position opposite to the push plate, the push plate is driven by the ejection cylinder to move in the direction close to the discharge conveyor belt to push the unqualified impeller segment off the discharge conveyor belt, thereby achieving the ejection of the unqualified impeller segment.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. When inspecting the impeller segments, the grabbing mechanism grabs the impeller segments to be inspected from the feeding conveyor belt and moves them to the limit block on the inspection table. After the image information of the impeller segments is obtained by the image acquisition component on the inspection table and fed back to the control system, the grabbing mechanism grabs the inspected impeller segments from the limit block and moves them to the discharging conveyor belt. The qualified impeller segments are transmitted through the output end of the discharging conveyor belt, and the unqualified impeller segments are removed from the discharging conveyor belt by the control system under the control of the rejection mechanism, thereby realizing automatic inspection and screening of the impeller segments, which is beneficial to improving the inspection and screening efficiency of the impeller segments.

[0024] 2. When the grasping structure grasps and moves the impeller segment, the manipulator drives the end support ring to enter the inner periphery of the target impeller segment, and then inflates the annular limiting airbag on the outer periphery of the support ring to expand the annular limiting airbag and press against the inner sides of several arc-shaped blades of the impeller segment, thereby achieving a stable grasp of the impeller segment.

[0025] 3. By supporting a cleaning air knife on the test bench and directing the cleaning air knife toward the outer periphery of the limit block, the impeller segment to be tested is subsequently inserted into the limit block through a grabbing mechanism. The impeller segment driven by the rotating drive unit first rotates around the limit block, and the cleaning air knife is used to blow compressed air toward the impeller segment mounted on the limit block to remove debris adhered to the arc-shaped blades on the impeller segment to be tested, thereby reducing the situation where the debris affects the judgment of the subsequent control system.

[0035] The following is combined with Figure 1-8 This application is described in further detail.

[0036] Reference 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 .

[0037] The present application discloses a crossflow fan impeller detection device, referring to Figure 2 and Figure 3 , including a control system, a feeding conveyor belt 2, a detection mechanism 3, a discharging conveyor belt 4 and a grabbing 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 platform 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 inserted, and the image acquisition component is arranged near the limit block 32. The discharging conveyor belt 4 is used to convey the impeller segment 1 that has been inspected, and the discharging conveyor belt 4 is provided with a material removal component 41. The grabbing mechanism 5 is arranged near the feeding conveyor belt 2, the detection mechanism 3 and the discharging conveyor belt 4, and is used to grab the impeller segment 1 to be detected on the feeding conveyor belt 2 and insert it into the limit block 32, and also to grab the impeller segment 1 that has been inspected on the limit block 32 from the limit block 32 and put it into the discharging conveyor belt 4.

[0038] The image acquisition component and the material removal component 41 are both electrically connected to the control system. The image acquisition component is used to acquire the image information of the impeller segment 1 mounted on the limit block 32 and feed it back to the control system. The control system is used to determine whether the liquid-cooled segment arc blade 12 is qualified based on the image information fed back by the image acquisition component, and control the material removal component 41 to remove the unqualified impeller segment 1 from the discharge conveyor belt 4 based on the judgment result; it is a prior art for the control system to determine whether the product is qualified by feeding back image information, which will not be elaborated here.

[0039] Reference Figure 3 and Figure 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] Through the setting of the image acquisition component, when the image information of the impeller segment 1 on the limit block 32 is subsequently acquired through the image, the sliding cylinder 352 drives the support 351 to drive the driving wheel 353 to move toward the direction close to the limit block 32 until the driving wheel 353 abuts against the outer side of the impeller segment 1 mounted on the outer periphery of the limit block 32, and 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 the inner and outer side images of the arc blades 12 at various locations on the impeller segment 1 and feed them back to the control system, so that the control system can judge whether the arc blades 12 on the impeller segment 1 are qualified according to the feedback image.

[0044] An auxiliary lighting fixture 311 is also installed above the limit block 32, and the auxiliary lighting fixture 311 is connected to the test platform 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 obtain image information of the impeller segment 1 more clearly.

[0045] Reference Figure 3 and Figure 4 A cleaning air knife 36 is also vertically supported on the detection platform. The air outlet of the cleaning air knife 36 is arranged toward the outer periphery of the limit block 32. The cleaning air knife 36 is staggered between the first CCD camera 33 and the second CCD camera 34. Before the image information of the impeller segment 1 is subsequently acquired by the first CCD camera 33 and the second CCD camera 34, the cleaning air knife 36 first blows compressed air toward the impeller segment 1 located on the limit block 32, and cooperates with the rotation drive unit 35 to drive the impeller segment 1 to rotate, so as to achieve the cleaning of several arc-shaped blades 12 on the impeller segment 1, which is conducive to removing the adhering debris on the arc-shaped blades 12, and reducing the misjudgment of the subsequent control system due to the debris adhering to the arc-shaped blades 12 of the impeller segment 1.

[0046] Reference Figure 2 and Figure 5 , the material removal component 41 is located on one side of the discharge conveyor belt 4, and the material removal component 41 includes a material removal cylinder 411, which is horizontally supported on the outside of the discharge conveyor belt 4 by a bracket, and the material removal cylinder 411 is arranged toward the discharge conveyor belt 4, and the material removal cylinder 411 is higher than the discharge conveyor belt 4. The piston rod of the material removal cylinder is connected with a push plate 412; the material removal cylinder 411 is electrically connected to the control system. Later, when the discharge conveyor belt 4 conveys the unqualified impeller segment 1 to be opposite to the push plate 412, the control system controls the material removal cylinder 411 to drive the push plate 412 to move in a direction close to the discharge conveyor belt 4, so as to use the push plate 412 to push the unqualified impeller segment 1 from the discharge conveyor belt 4, so as to remove the unqualified impeller segment 1. There is a gap between the bottom of the push plate 412 and the conveying surface of the discharge conveyor belt 4, which is conducive to limiting the interference between the push plate 412 and the discharge conveyor belt 4 during the subsequent movement.

[0047] A qualified product collection box 42 is placed below the output end of the discharge conveyor belt 4. The impeller segments 1 that have passed the subsequent inspection can fall into the qualified product collection box 42 after being output through the output end of the discharge conveyor belt 4, thereby collecting 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 lifting assembly. The unqualified impeller segments 1 that are subsequently pushed out by the push plate 412 can fall into the defective product collection box 43, thereby collecting the unqualified impeller segments 1.

[0048] Reference Figure 6 and Figure 7The grabbing mechanism 5 includes a manipulator 51 and a grabbing part 52. The grabbing part 52 is connected to the driving end of the manipulator 51 and is used to grab the impeller segment 1. In this embodiment, the manipulator 51 is specifically a five-axis manipulator 51. The grabbing part 52 includes a support ring 521. The support ring 521 is coaxially connected to a support rod 523. The end of the support rod 523 away from the support ring 521 is coaxially connected to a flange 524. The flange 524 is connected to the driving end of the manipulator 51 by bolts. An annular limiting airbag 522 is sleeved on the outer periphery of the support ring 521. An annular limiting groove 5211 is circumferentially opened 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, so that the annular limiting airbag 522 is firmly installed on the outer periphery of the support ring 521.

[0049] Reference Figure 7 and Figure 8 When the impeller segment 1 is grasped by the grasping mechanism 5, the manipulator 51 drives the support ring 521 to enter the inner periphery of the target impeller segment 1, and then inflates the annular limiting airbag 522, so that the annular limiting airbag 522 expands and presses against the inner sides of several arc-shaped blades 12 of the impeller segment 1. Compared with the conventional clamping method of clamping objects by relatively moving clamping parts, the grasping part 52 can realize the stable grasping of the impeller segment 1 on the inner periphery of the impeller segment 1, effectively reducing the situation that the grasping part 52 is restricted in movement due to space limitations; at the same time, the expanded annular limiting airbag 522 is pressed against the outer periphery of several arc-shaped blades 12 to grasp the impeller segment 1 stably, which is conducive to reducing the situation that when the conventional clamping device clamps the impeller segment 1 by relatively moving clamping parts, the clamped arc-shaped blades 12 are locally deformed by force, resulting in unstable clamping of the impeller segment 1. When the impeller segment 1 is grasped by the grasping mechanism 5, the gas in the annular limiting airbag 522 is released, and the impeller segment 1 can be grasped.

[0050] The implementation principle of the embodiment of the present application is: the arc-shaped blade 12 of the impeller segment 1 to be inspected is placed upward on the input end of the feeding conveyor belt 2, and after the impeller segment 1 to be inspected is transported to the output end by the feeding conveyor belt 2, it is grasped by the grasping mechanism 5 and inserted into the limit block 32 of the inspection table 31, and then the grasping mechanism 5 contacts the impeller segment 1 and moves away from the impeller segment 1.

[0051] The cleaning air knife 36 on the detection table 31 blows compressed air toward the impeller segment 1 on the limit table, and at the same time, the rotation drive part 35 drives the impeller segment 1 on the limit block 32 to rotate, so as to clean the impeller segment 1. After cleaning is completed, the cleaning wind knife 36 stops blowing compressed air, and the rotation drive unit 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 obtain image information of the arc blades 12 on the impeller segment 1 and immediately feed it back to the control system. The control system determines whether the arc blades 12 of the inspected impeller segment 1 are qualified based on the feedback image information.

[0052] The impeller segment 1 that has completed the inspection is transferred from the limit block 32 to the discharge conveyor belt 4 through the grabbing mechanism 5. The impeller segment 1 that has passed the inspection is transmitted through the output end of the discharge conveyor belt 4 and falls into the qualified product collection box 42. When the impeller segment 1 that has failed the inspection is transferred to the ejection component 41 by the discharge conveyor belt 4, the control system controls the ejection cylinder 411 to drive the push plate 412 to push it down to the defective product collection box 43.

[0053] The present application can realize automatic detection and screening of the impeller segments 1 of the crossflow fan, and effectively improve the detection and screening efficiency of the impeller segments 1.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
