Description

Technical Field

[0001] The present invention relates to the technical field of stator detection, and in particular to an automatic detection device for a motor stator. Background Art

[0002] As one of the core components of the motor, the performance and quality of the motor stator directly affect the overall operation and life of the motor. Therefore, comprehensive and accurate inspection of the motor stator is an indispensable part of the motor manufacturing and maintenance process. Through inspection, possible defects and problems of the stator can be found in time, such as appearance defects, poor insulation, winding open circuit and inter-turn short circuit, so as to ensure the normal operation and reliability of the motor.

[0003] However, the motor stator automatic inspection equipment in the prior art can quickly inspect the motor stators through the inspection box and the automatic inspection mechanism, but lacks the classification of qualified products and unqualified products. Among them, the motor stators with unqualified appearance can be directly eliminated without further inspection. The existing device will indiscriminately inspect all motor stators, thereby wasting inspection resources and affecting inspection efficiency.

[0004] In summary, how to solve the problem that the motor stator automatic detection equipment in the prior art will perform indiscriminate detection on all motor stators, thereby wasting detection resources and affecting detection efficiency has become a difficult problem that needs to be solved urgently in the current field. Therefore, it is necessary to propose a motor stator automatic detection equipment that can eliminate motor stators that fail the appearance inspection in advance and avoid invalid detection. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a motor stator automatic inspection equipment, which can effectively identify stators with defects in appearance through the design of the identification component, and cooperate with the design of the interception component, the first conveyor and the loading component to eliminate the stators with unqualified appearance and send the stators with qualified appearance for inspection, thereby avoiding invalid inspection, improving the inspection time and the utilization rate of inspection resources, and improving the inspection efficiency.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a motor stator automatic detection device, including a base, a first conveyor of a conveying rod type is fixedly connected to the base, the first conveyor is provided with an interception component for intercepting the stator, and the first conveyor is provided with an identification component for performing an appearance inspection on the stator on the side close to the interception component; the first conveyor is also provided with a loading component for loading the stator on the side close to the interception component.

[0007] An H-shaped support frame is provided on the side of the first conveyor close to the identification component. The support frame includes vertical rods, horizontal rods and straight rods. The vertical rods, horizontal rods and straight rods are spliced ​​in sequence along the width direction of the base to form an H shape. The bottom of the straight rod is fixedly connected to the base, and a driving component for driving the loading component is provided on the straight rod.

[0008] The driving assembly includes a main chain, and main gears are meshed at both ends of the inner wall of the main chain. The main gears are rotatably matched with the side of the straight rod close to the vertical rod. A motor is fixedly connected to the side of the straight rod away from the vertical rod, and the motor output shaft is coaxially fixedly connected to one of the main gears; the motor is electrically connected to a controller, and the controller is used to control the opening and closing of the motor.

[0009] The loading assembly includes a secondary chain, both ends of the inner wall of the secondary chain are meshed with secondary gears, the secondary gears are rotatably cooperated with the side of the vertical rod away from the straight rod, a number of loading baskets are hinged on the secondary chain, and a number of loading rods are fixedly connected to the side of the loading baskets away from the secondary chain; a number of loading ports for the loading baskets to pass through are opened on the side of the first conveyor close to the identification assembly, and the conveying rods at the loading ports are staggered with the loading rods.

[0010] The main chain is provided with a transmission assembly for transmitting power to the auxiliary chain.

[0011] A testing box is fixedly connected to the base, a testing component for testing the stator is arranged below the testing box, and a clamping component for clamping the stator is arranged on the outer wall of the testing box.

[0012] The technical principles of the above scheme are as follows:

[0013] The stators are placed on the first conveyor at a fixed interval, and the first conveyor transports the stators toward the identification component. When the identification component identifies defects in the appearance of the stator, the controller controls the interception component to stop intercepting the stator. At this time, the stator will be transported to the end by the first conveyor for elimination.

[0014] When the identification component recognizes that there are no defects in the appearance of the stator, the controller determines that the stator appearance inspection is qualified; at this time, the controller controls the interception component to keep intercepting the stator and starts the motor; the motor output shaft drives one of the main gears to rotate, and the rotation of the main gear drives the main chain to rotate, and the main chain drives the remaining main gears to rotate; the main gears at both ends of the main chain keep the main chain taut, so that the rotation is smoother.

[0015] When the main chain rotates, the rotational torque of the main chain will be transmitted to the secondary chain through the transmission assembly, thereby causing the secondary chain to rotate; the secondary gears at both ends of the secondary chain keep the secondary chain tensioned, so that the rotation is smoother; when the secondary chain rotates, since the loading basket is hinged with the secondary chain, the secondary chain will drive the loading basket to rotate, and since the transmission assembly can keep the loading basket horizontal, when the loading basket passes through the loading port, since the transmission rods at the loading port are staggered with the loading rods, when the stator is intercepted at the loading port by the interception assembly, the loading rod will load the stator through the transmission rod at the loading port.

[0016] At this time, the stator is loaded into the loading basket and transported to the inspection assembly for inspection as the secondary chain rotates. The inspection assembly sends the stator to the bottom of the clamping assembly, and the clamping assembly clamps the stator. At this time, the inspection box will perform insulation resistance test, DC resistance test, turn-to-turn short circuit test and withstand voltage test on the stator.

[0017] The above scheme has the following beneficial effects:

[0018] 1. The present invention can automatically identify stators with appearance defects through the design of the identification component, and then through the design of the interception component, only the stators that have passed the appearance inspection are retained, and the stators that have failed the appearance inspection are eliminated in real time; and through the interlaced design of the first conveyor loading port and the loading basket, the stators that have passed the appearance inspection are sent to the inspection box for further inspection. Such a design can eliminate motor stators that have failed the appearance inspection in advance, avoid invalid inspections, improve the inspection time and the utilization rate of inspection resources, and significantly improve the inspection efficiency.

[0019] 2. The entire inspection process requires almost no direct human involvement. From stator feeding, appearance inspection to stator loading, stator inspection and stator inspection, all are completed automatically by the equipment. This greatly reduces the complexity and labor intensity of manual operation, and also reduces the impact of human factors on the inspection results, avoiding damage to the stator during manual inspection and avoiding harm to workers.

[0020] 3. Due to the selection of the first conveyor with a conveyor rod, the stator will be located between the gaps of adjacent conveyor rods, which prevents the stator from rolling and causing the stators to collide with each other, making the feeding process more stable. The loading rod also uses the same principle, so that the loading basket can stably load the stator and prevent the stator from rolling.

[0021] Furthermore, the transmission assembly includes a center plate, and a cross bar passes through the center plate; the bottom of the center plate is fixedly connected to the top of the base; an annular groove is opened on the center plate, and a step rod is slidably fitted in the annular groove, and the side wall of the step rod near one end of the main chain is hinged to the side wall of the main chain, and the step rod near one end of the secondary chain is fixedly connected to the side wall of the loading basket.

[0022] Beneficial effect: The transmission assembly realizes stable transmission from the main chain to the secondary chain through the sliding cooperation between the annular groove on the center plate and the step rod. This design ensures that when the main chain rotates, the power can be smoothly transmitted to the secondary chain, thereby driving the rotation of the loading basket.

[0023] At the same time, one end of the step rod is hinged to the side wall of the main chain, and the other end is fixedly connected to the side wall of the loading basket. This connection method allows the loading basket to remain horizontal while rotating with the secondary chain. This is crucial for loading and transporting the stator, because maintaining horizontality ensures that the stator is stable in the loading basket without shaking, avoiding collision or damage during transportation.

[0024] Furthermore, the interception assembly includes a telescopic rod fixedly connected to the first conveyor, and the controller is used to control the opening and closing of the telescopic rod.

[0025] Beneficial effect: When the recognition component identifies a stator with a qualified appearance, the controller will start the telescopic rod to extend and accurately intercept the stator. This precise interception method prevents the stator from moving forward and ensures that only qualified stators can enter the next step of the inspection process. On the contrary, the controller will control the telescopic rod to retract, so that the stator is conveyed to the end by the first conveyor for elimination.

[0026] Furthermore, the identification component includes a camera fixedly connected to the first conveyor, and the controller is used to receive image information collected by the camera, and the controller has recorded therein an image of the stator that has passed the appearance inspection for comparison.

[0027] Beneficial effect: The camera can compare the image of the stator being inspected with the image of a qualified stator to detect whether there are defects in the appearance of the stator. If there are defects, the controller will determine that the stator appearance inspection is unqualified, and cooperate with the interception component and the first conveyor to eliminate the stator.

[0028] Furthermore, the clamping assembly includes a back plate, an electric cylinder is embedded and installed on the upper part of the back plate, a slider is fixedly connected to the output shaft of the electric cylinder, and a convex groove is opened on the back plate for the extension and retraction of the output shaft of the electric cylinder and the sliding of the slider; folding blocks are symmetrically hinged on both sides of the lower part of the back plate, and pulleys are fixedly connected to the side walls at both ends of the folding blocks; a horizontal groove is opened on the slider, and the pulleys at one end of the folding block close to the slider are slidably matched with the horizontal groove; clamping blocks are symmetrically slidably matched on both sides of the bottom of the back plate, and vertical grooves are opened on the clamping blocks, and the pulleys at one end of the folding block close to the clamping block are slidably matched with the vertical grooves; the controller is used to control the opening and closing of the electric cylinder.

[0029] Beneficial effect: when the stator is located below the clamping block, the controller will control the electric cylinder to start, and at this time the output shaft of the electric cylinder will pull the slider upward; as the slider slides upward in the convex groove, the horizontal groove will generate an upward force on the folding block, but since the folding block is hinged with the back plate, the back plate limits the folding block, so that the pulley at the end of the folding block close to the slider will slide to both sides in the horizontal groove, and the end of the folding block close to the slider will also rotate outward. At this time, due to the principle of lever, the end of the folding block close to the clamping block will rotate inward, and the pulley at the end of the folding block close to the clamping block will slide upward in the vertical groove. At the same time, since the clamping block pushes and slides symmetrically on both sides of the bottom of the back plate, the folding block will push the clamping block inward through the pulley, thereby clamping the stator, making it easier for the detection box to detect it.

[0030] Furthermore, the inspection component includes a second conveyor of a conveying rod type, the second conveyor is fixedly connected to the top of the base, and the second conveyor is located between the secondary chain and the inspection box; a plurality of receiving ports are opened on the side wall of the second conveyor, and the conveying rods at the receiving ports are staggered with the loading rods; the second conveyor is located below the inspection box and the clamping block.

[0031] Beneficial effect: The second conveyor receives the stator through the receiving port and sends the stator to the bottom of the clamping block. At this time, the controller stops the rotation of the second conveyor to facilitate the clamping block to clamp the stator, so that the detection box can detect the stator. The staggered setting of the transmission rod and the loading rod at the receiving port ensures that the stator released from the clamping assembly can smoothly fall between the transmission rods of the second conveyor without being blocked or stuck.

[0032] Furthermore, a plurality of protective plates are fixedly connected to the side walls of the loading basket.

[0033] Beneficial effect: The protective plate can further prevent the stator from rolling and falling, thereby better transporting and protecting the stator and providing a good foundation for subsequent inspection work.

[0034] Furthermore, a defective product box is provided below one end of the first conveyor close to the second conveyor, and the bottom of the defective product box is fixedly connected to the top of the base.

[0035] Beneficial effect: When the camera identifies a stator that fails the appearance inspection, the controller controls the telescopic rod to retract, and the stator will be conveyed to its end by the first conveyor and finally fall into the defective box for centralized collection.

[0036] Furthermore, a collecting box is provided below one end of the second conveyor away from the first conveyor, the bottom of the collecting box is fixedly connected to the top of the base, and a sponge layer is fixedly connected to the inner wall of the collecting box.

[0037] Beneficial effects: When the stator is inspected, the second conveyor will convey the stator to its end and then drop it into the collection box, so that the inspected stators can be stored in an orderly manner, avoiding the stators from being scattered or piled up around the equipment, thus keeping the production site clean and orderly. This is not only conducive to improving the quality of the production environment, but also helps to improve production efficiency and safety. The sponge layer in the collection box plays a role of buffering and protection. When the stator falls into the collection box, the sponge layer can absorb the impact force, reduce the collision and friction between the stator and the bottom of the box, and thus protect the stator from damage.

[0038] Furthermore, a plurality of infrared transmitters are fixedly connected to the bottom of the clamping block, a plurality of infrared sensors are fixedly connected to the second conveyor, and the controller is used to receive signals from the infrared sensors.

[0039] Beneficial effect: When the stator is located at the bottom of the clamping block, the infrared rays emitted by the infrared transmitter will be blocked, and the infrared sensor will not sense the corresponding infrared rays. At this time, the controller will control the telescopic rod to start, so as to accurately clamp the stator.

DETAILED DESCRIPTION

[0048] The following is further described in detail through specific implementation methods:

[0049] Embodiment 1:

[0056] The main chain 10 is provided with a transmission assembly for transmitting power to the secondary chain 6 .

[0057] The transmission assembly includes a center plate 4, such as Figure 6 As shown, the cross bar passes through the middle of the center plate 4; the bottom of the center plate 4 is welded to the top of the base 1; an annular groove is opened on the center plate 4, and a step rod 8 is slidably fitted in the annular groove. The side wall of the step rod 8 close to the main chain 10 is hinged to the side wall of the main chain 10, and the end of the step rod 8 close to the auxiliary chain 6 is welded to the side wall of the loading basket 7; Figure 5 For reference, the main chain 10 and the auxiliary chain 6 are located on both sides of the center plate 4 respectively.

[0058] A testing box 20 is fixedly connected to the base 1 by bolts. A testing assembly for testing the stator is provided below the testing box 20 , and a clamping assembly for clamping the stator is provided on the outer wall of the testing box 20 .

[0059] The clamping assembly includes a back plate 18, on which an electric cylinder 14 is vertically embedded and installed, and the output shaft of the electric cylinder 14 is bolted and fixedly connected with a slider 15, and the back plate 18 is provided with a convex groove for controlling the extension and retraction of the output shaft of the electric cylinder 14 and the sliding of the slider 15; folding blocks 16 are symmetrically hinged on both sides of the lower part of the back plate 18, and pulleys are fixedly connected to the side walls at both ends of the folding blocks 16; the slider 15 is provided with a horizontal groove, and the pulleys at one end of the folding block 16 close to the slider 15 are slidably matched with the horizontal groove; the clamping blocks 17 are symmetrically slidably matched on both sides of the bottom of the back plate 18, and the clamping blocks 17 are provided with vertical grooves, and the pulleys at one end of the folding block 16 close to the clamping block 17 are slidably matched with the vertical grooves; the controller is used to control the opening and closing of the electric cylinder 14.

[0060] The inspection component includes a second conveyor 13 of a conveying rod type, and the second conveyor 13 is fixedly connected to the top of the base 1; a plurality of receiving ports are opened on the side wall of the second conveyor 13, and the conveying rods at the receiving ports are staggered with the loading rod 701; the second conveyor 13 is located below the inspection box 20 and the clamping block 17.

[0061] A plurality of infrared transmitters 23 are fixedly bonded to the bottom of the clamping block 17, and a plurality of infrared sensors are fixedly bonded to the second conveyor 13. The controller is used to receive signals from the infrared sensors to identify the position of the stator.

[0062] The first conveyor 2 and the second conveyor 13 are respectively located at both sides of the secondary chain 6 , and the second conveyor 13 is located between the secondary chain 6 and the detection box 20 .

[0063] The specific implementation process is as follows:

[0064] The stators are evenly placed on the first conveyor 2 at intervals of 30 cm. Since the first conveyor 2 is a conveyor rod type, the stators will be located between the gaps between adjacent conveyor rods, which can effectively prevent the stators from rolling.

[0065] like Figure 1 As shown, the first conveyor 2 transports the stator toward the camera 19. When the controller recognizes that there are defects in the appearance of the stator through the camera 19, the controller will control the telescopic rod 3 to retract and will not intercept the stator. At this time, the stator will be transported to the end by the first conveyor 2 and wait for subsequent recycling processing.

[0066] When the controller recognizes that there is no defect in the appearance of the stator through the camera 19, the controller determines that the stator appearance inspection is qualified; at this time, the controller controls the telescopic rod 3 to remain in the extended state, so that the telescopic rod 3 intercepts the stator; at the same time, the controller starts the motor 11, and the output shaft of the motor 11 drives the main gear 9 fixed with the bolts to rotate, and the rotation of the main gear 9 drives the main chain 10 to rotate, and the main chain 10 drives the other main gears 9 to rotate; the main gears 9 at both ends of the main chain 10 keep the main chain 10 taut, so that the rotation is smoother;

[0067] like Figure 5 and Figure 6 As shown, when the main chain 10 rotates, since the main chain 10 is hinged to the step rod 8, the main chain 10 will drive the step rod 8 to rotate; since the step rod 8 is hinged to the loading basket 7, the loading basket 7 will move circumferentially along the annular groove with the step rod 8, and since the loading basket 7 and the auxiliary chain 6 are hinged, the rotational torque of the main chain 10 will be transmitted to the auxiliary chain 6 through the step rod 8 and the loading basket 7, thereby causing the auxiliary chain 6 to rotate; the auxiliary gears 12 at both ends of the auxiliary chain 6 keep the auxiliary chain 6 tensioned, so that the rotation is smoother; when the auxiliary chain 6 rotates, since the loading basket 7 is hinged to the auxiliary chain 6, the auxiliary chain 6 will further drive the loading basket 7 to rotate, so that the loading basket 7 rotates more smoothly.

[0068] like Figure 5 As shown, since one end of the step rod 8 is hinged to the main chain 10, the other end of the step rod 8 is fixed to the loading basket 7, and the secondary chain 6 is driven by the main chain 10, the secondary chain 6 has the same rotation frequency as the main chain 10; therefore, when the main chain 10 rotates, due to the limitation of the loading basket 7 and the gravity of the lower part of the step rod 8, the step rod 8 always remains vertical, and the loading basket 7 can always remain horizontal due to the fixation of the step rod 8, so that the loading rod 701 can pass through the loading port and the receiving port.

[0069] like Figure 1 , Figure 2 and Figure 3 As shown, when the loading basket 7 passes through the loading port, since the conveying rods at the loading port are staggered with the loading rod 701, when the stator is intercepted by the interception assembly at the loading port, the loading rod 701 will load the stator through the conveying rod at the loading port. At this time, the stator is loaded by the loading basket 7 and transported to the second conveyor 13 as the secondary chain 6 rotates.

[0070] At this time, since the conveying rods at the receiving port are offset from the loading rods 701; when the loading basket 7 passes through the receiving port, the conveying rods at the receiving port will stop the stator in the loading basket 7. At this time, the controller starts the second conveyor 13. When the stator is conveyed to the bottom of the clamping block 17, the stator will block the infrared rays emitted by the infrared transmitter 23, and the infrared sensor will not sense the corresponding infrared rays. At this time, the controller can accurately determine the position of the stator according to the range of the infrared rays blocked. When the stator is located directly below the clamping block 17, the controller will control the second conveyor 13 to be stationary, and at the same time control the electric control cylinder 14 to start, so as to accurately clamp the stator.

[0071] like Figure 4 As shown, during the clamping process, the controller will control the output of the electric cylinder 14 to retract upward, and at this time the output shaft of the electric cylinder 14 will pull the slider 15 upward; since the slider 15 slides upward in the convex groove, the horizontal groove will generate an upward force on the folding block 16, and since the folding block 16 is hinged with the back plate 18, the back plate 18 limits the folding block 16, so that the pulley at the end of the folding block 16 close to the slider 15 will slide to both sides in the horizontal groove, and the end of the folding block 16 close to the slider 15 will also rotate outward accordingly. At this time, due to the principle of leverage, the end of the folding block 16 close to the clamping block 17 will rotate inward, and the pulley at the end of the folding block 16 close to the clamping block 17 will slide upward in the vertical groove. At the same time, since the clamping block 17 pushes and slides symmetrically on both sides of the bottom of the back plate 18, the folding block 16 will push the clamping block 17 to move inward through the pulley, thereby clamping and fixing the stator.

[0072] After the stator is clamped and fixed, the detection box 20 will automatically perform insulation resistance detection, DC resistance detection, turn-to-turn short circuit detection and withstand voltage test on the stator.

[0073] After the stator detection is completed, the controller will control the output of the electric control cylinder 14 to move downward. At this time, the slider 15 moves downward, causing the upper part of the folding block 16 to rotate inward, and the lower part of the folding block 16 to rotate outward, thereby driving the clamping block 17 to rotate outward, so that the clamping effect of the clamping block on the stator disappears. At this time, the controller starts the second conveyor 13, and the stator arrives at the end of the second conveyor 13 with the second conveyor 13 and is collected and processed.

[0074] Embodiment 2:

[0075] As attached Figure 1 , Figure 3 As shown, the difference from the above embodiment is that a plurality of protective plates 702 are welded to the side walls of the loading basket 7 .

[0076] The specific implementation process is as follows: when the stator is located in the loading basket 7, the protective plate 702 can further prevent the stator from rolling and falling, thereby better transporting and protecting the stator and providing a good foundation for subsequent detection work.

[0077] Embodiment 3:

[0078] As attached Figure 1 As shown, the difference from the above embodiment is that a defective product box 22 is provided below one end of the first conveyor 2 close to the second conveyor 13 , and the bottom of the defective product box 22 is fixedly connected to the top of the base 1 by bolts.

[0079] The specific implementation process is as follows: when the camera 19 identifies a stator that fails the appearance inspection, the controller controls the telescopic rod 3 to retract, and the stator will be conveyed to its end by the first conveyor 2 and finally fall into the defective box 22 for centralized collection.

[0080] Embodiment 4:

[0081] As attached Figure 1 As shown, the difference from the above embodiment is that a collecting box 21 is provided below the end of the second conveyor 13 away from the first conveyor 2, the bottom of the collecting box 21 is fixedly connected to the top of the base 1, and a sponge layer is fixedly bonded to the inner wall of the collecting box 21.

[0082] The specific implementation process is as follows: When the stator is inspected, the second conveyor 13 will convey the stator to its end, and then drop it into the collection box 21, so that the inspected stators can be stored in order for subsequent processing, avoiding the stators from being scattered or piled up around the equipment, thereby keeping the production site clean and orderly. This is not only conducive to improving the quality of the production environment, but also helps to improve production efficiency and safety. The sponge layer in the collection box 21 plays a role of buffering and protection. When the stator falls into the collection box 21, the sponge layer can absorb the impact force, reduce the collision and friction between the stator and the bottom of the box, and thus protect the stator from damage.

[0083] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
