Description

TECHNICAL FIELD

[0001] The present application relates to material receiving and transferring technical field, in particular to a motor lamination receiving device with detection function. BACKGROUND

[0002] The motor stator is an important component of the motor such as generator and starter. Among them, the stator core is an important component of the motor magnetic circuit, and the stator core is composed of fan-shaped pieces, ventilation slot pieces, positioning ribs, upper and lower tooth pressure plates, tension bolts and supporting plates. The stator core is punched into fan-shaped pieces by silicon steel sheets, i.e. motor laminations, which are stacked on the positioning ribs, and the positioning ribs are welded on the ring plate of the machine base through the supporting plate, and the iron core is pressed into a whole by the tension bolts through the upper and lower tooth pressure plates.

[0003] The material of motor lamination is usually silicon steel sheet. Silicon steel sheet is a thin steel plate with very low carbon content. In order to obtain feasible low hysteresis loss, it is produced under special control conditions. Generally, pure iron is not suitable for alternating magnetic field, mainly because its resistivity is small, which will cause large eddy current loss. After adding silicon element, the resistivity is improved because silicon and iron form a solid solution alloy. Silicon steel sheet is to reduce the eddy current loss caused by the thickness direction by increasing the resistivity. Eddy current loss is proportional to the thickness of silicon steel sheet, and the thickness of silicon steel sheet used in the iron core is usually 0.35-0.5mm.

[0004] The dimensional accuracy of motor lamination will affect the formation of the magnetic circuit inside the motor, and will significantly affect the service life of the motor. In the process of forming motor lamination, abnormal deformation may occur in each stage of elastic deformation, plastic deformation, shearing stage and separation stage during the deformation process of motor lamination, which will lead to the decrease of the precision of motor lamination. Therefore, it is necessary to detect the precision of motor lamination during the receiving and collecting process of motor lamination from the punching machine. However, the existing motor lamination receiving device usually does not have detection function, and the precision detection of motor lamination is not accurate, which makes it difficult to quickly adjust the front-end production according to the precision of motor lamination, resulting in large tolerance of the output motor lamination and low product yield.

[0005] At present, there is no effective solution to the problems in the related art. SUMMARY

When the enclosed plate is driven by the lifting drive guide rail, the limiting block moves into the rotating track, and the limiting block can rotate under the restriction of the rotating track.

[0014] Preferably, when the enclosed plate moves to the bottom of the drive frame, the limiting block moves into the interior of the rotating track; at this time, the rotary drive motor can drive the enclosed plate to rotate around the driven shaft through the engagement of the drive pin and the connecting pin groove; when the motor lamination is qualified, the rotary drive motor drives the enclosed plate to rotate forward and point towards the good product channel, guiding the motor lamination supported by the enclosed plate to the good product channel; when the motor lamination is unqualified, the rotary drive motor drives the enclosed plate to rotate in the reverse direction and point towards the defective product channel, guiding the motor lamination supported by the enclosed plate to the defective product channel.

[0018] Compared with the prior art, the present invention provides a receiving device for motor laminations with detection function, which has the following beneficial effects:

[0019] 1. This type of motor lamination receiving device with detection function uses a detection mechanism set directly above the detection platform to detect the motor laminations inside the detection groove. The enclosed plate can collect non-compliant motor laminations output from the defective product channel based on the detection results, and then repair or destroy them for remanufacturing, thus preventing the production of defective motor laminations. When the motor laminations are qualified, they continue to be conveyed through the good product channel. A central conveying mechanism sorts the qualified motor laminations, and a stacking and collecting mechanism neatly stacks them for easy packaging in the later stages. This effectively ensures the yield rate of the output products. Furthermore, under the detection of the detection mechanism, adjustments can be made to the production front end, such as the laminations, based on the error value between the actual detection results and the standard motor laminations. This effectively ensures the yield rate of the output while also preventing damage to the front-end punching mechanism caused by incorrect front-end laminations, and effectively avoiding a decrease in front-end processing accuracy due to incorrect front-end laminations, thus fully guaranteeing the yield rate of the finished products.

[0020] 2. In this type of receiving device for motor laminations with detection function, after the detection mechanism completes the detection of the motor laminations inside the detection groove, the lifting drive guide rail drives the closed plate to move. Because the limit block can only move up and down under the limitation of the lifting rail, the closed plate can only move downward along the straight line of the positioning line and away from the detection groove under the drive of the lifting drive guide rail until the closed plate moves to the lowest point limited by the lifting guide rail, providing rotation space for the closed plate. At this time, the limit block moves into the rotation track, rotating the drive pin of the drive motor. It can be embedded inside the connecting pin groove. The rotary drive motor can drive the closed plate to rotate around the driven shaft through the engagement of the drive pin shaft and the connecting pin groove. When the motor lamination is qualified, the rotary drive motor drives the closed plate to rotate in the forward direction and point towards the good product channel, guiding the motor lamination supported by the closed plate to the good product channel. When the motor lamination is unqualified, the rotary drive motor drives the closed plate to rotate in the reverse direction and point towards the defective product channel, guiding the motor lamination supported by the closed plate to the defective product channel, thereby separating the good and defective motor laminations and ensuring the yield rate of the final product.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a receiving device for motor laminations with detection function.

[0032] Please see Figures 1-8A receiving device for motor laminations with detection function includes: an inclined slide 1 and a detection platform 2. A detection mechanism 3 is disposed directly above the detection platform 2. A detection groove 21 is disposed in the center of the detection platform 2, with an opening at the bottom end of the groove. A selective feeding mechanism 4 is disposed below the detection platform 2. The selective feeding mechanism 4 includes a closed plate 41, a good product channel 42, and a defective product channel 43. After lamination is completed, the motor laminations slide one by one through the inclined slide 1 into the detection groove 21 in the center of the detection platform 2. The closed plate 41 closes the bottom opening of the detection groove 21 before the detection mechanism 3 completes its detection of the motor laminations inside the groove 21. After the detection mechanism 3 completes its detection of the motor laminations inside the groove 21... According to the test results of the testing agency 3, the closed plate 41 supports the motor laminations to descend and rotate; when the motor laminations are qualified, the closed plate 41 rotates and points towards the good product channel 42, guiding the motor laminations supported by the closed plate 41 to the good product channel 42; when the motor laminations are unqualified, the closed plate 41 rotates and points towards the defective product channel 43, guiding the motor laminations supported by the closed plate 41 to the defective product channel 43; the tail end of the good product channel 42 is provided with a central conveying mechanism 5 and a stacking and collecting mechanism 6 in sequence. The motor laminations output from the good product channel 42 enter the interior of the central conveying mechanism 5, which centrally conveys the motor laminations and delivers them one by one to the stacking and collecting mechanism 6. Inside the stacking and collecting mechanism 6, the motor laminations are stacked and collected one by one before being output.

[0033] During use, the motor laminations formed by the punching machine are transferred to the top of the inclined slide 1 (in actual use, a conveying system can be set between the punching machine and the receiving device of the motor laminations with detection function, or it can be done manually, or the top of the inclined slide 1 can be directly set at the discharge port of the punching machine). Under the action of gravity, the motor laminations slide down the inclined slide 1 until they fall into the detection groove 21 set in the center of the detection platform 2, whose bottom opening is closed by the closed plate 41. The closed plate 41 provides support. Under the action of the detection mechanism 3, the motor laminations inside the detection groove 21 are inspected by the detection mechanism 3 located directly above the detection platform 2. Based on the detection results of the detection mechanism 3, the closed plate 41 rotates and points towards the defective product channel 43 when a motor lamination is found to be defective, guiding the motor lamination supported by the closed plate 41 to the defective product channel 43. The non-compliant motor laminations output from the defective product channel 43 are collected for repair or destruction and remanufacturing to prevent the production of defective motor laminations. When the product is qualified, the enclosed plate 41 rotates and points towards the good product channel 42, guiding the motor laminations supported by the enclosed plate 41 to the good product channel 42. At the end of the good product channel 42, a central conveying mechanism 5 and a stacking and collecting mechanism 6 are sequentially arranged. The motor laminations output from the good product channel 42 enter the central conveying mechanism 5, which centrally conveys the motor laminations and then transports them one by one to the stacking and collecting mechanism 6. Inside the stacking and collecting mechanism 6, the motor laminations are stacked and collected one by one before being output. The qualified motor laminations are then sorted by the central conveying mechanism 5 and collected in the stacking and collecting mechanism. The assembly mechanism 6 neatly stacks the sorted motor laminations to facilitate the subsequent packaging process, effectively ensuring the yield rate of the output products. Under the inspection of the testing mechanism 3, based on the error value between the actual test results and the standard motor laminations, the front-end production process, such as laminations, is fully adjusted. This effectively ensures the yield rate of the output while also preventing damage to the front-end punching mechanism caused by incorrect laminations. It also effectively avoids the decrease in front-end processing accuracy caused by incorrect laminations, thus fully guaranteeing the yield rate of the products leaving the factory.

[0034] Further, please refer to Figures 1-5 An interception groove 11 is provided on the upper surface of the inclined slide 1, and an interception plate 12 is provided inside the interception groove 11. The interception plate 12 can move inside the interception groove 11. When the interception plate 12 moves to the lowest point, the upper surface of the interception plate 12 is coplanar with the upper surface of the inclined slide 1. A linear guide rail 13 is provided on one side of the interception plate 12. The movable block of the linear guide rail 13 is fixed to the interception plate 12. The linear guide rail 13 is used to drive the interception plate 12 to move inside the interception groove 11 by driving the movable block to move.

[0035] In use, the movable block of the linear guide 13 drives the interceptor plate 12, which is fixed to the movable block, to move inside the interceptor groove 11. When there is a motor lamination inside the detection groove 21, the interceptor plate 12 rises inside the interceptor groove 11. At this time, the upper surface of the interceptor plate 12 exceeds the upper surface of the inclined slide 1. The interceptor plate 12 can prevent the rear motor lamination from re-entering the detection groove 21 and interfering with the detection process of the motor lamination inside the detection groove 21. When the closed plate 41 of the selective feeding mechanism 4 transfers the motor lamination after detection and the closed plate 41 re-closes the bottom of the detection groove 21, the linear guide 13 drives the interceptor plate 12 to descend until the interceptor plate 12 moves to the lowest point. The upper surface of the interceptor plate 12 is coplanar with the upper surface of the inclined slide 1, which can prevent the interceptor plate 12 from affecting the sliding of the motor lamination on the upper surface of the inclined slide 1 and ensure the smoothness of the motor lamination movement.

[0036] Further, please refer to Figures 1-5 The testing mechanism 3 includes a hoisting frame 31, with a testing camera 32 mounted in the center of the hoisting frame 31. The normal line of the bottom surface of the testing groove 21, which passes through the center point of the bottom surface of the testing groove 21, is used as the positioning line, and the viewing element of the testing camera 32 is located on the positioning line. The testing camera 32 can take several testing pictures of the motor laminations inside the testing groove 21. All testing pictures of the same motor lamination can be uploaded to the processing terminal. The processing terminal can compare all testing pictures of the same motor lamination with the standard motor lamination image to determine whether the motor lamination currently inside the testing groove 21 is qualified.

[0037] In practical use, the inspection camera 32 is a CCD camera. The central axis of the viewfinder of the inspection camera 32 is perpendicular to the bottom surface of the inspection groove 21 (which can also be considered as the upper surface of the closed plate 41), and the viewfinder of the inspection camera 32 is aligned with the center of the inspection groove 21. In actual use, the size of the inspection groove 21 is only slightly larger than the size of the motor lamination, and there are obvious positioning marks at the edge between the inspection groove 21 and the inspection platform 2. The inspection camera 32 takes several inspection images of the motor lamination inside the inspection groove 21, and the corresponding images of the motor lamination are... The inspection image is processed in the processing terminal. Edge processing technology is applied (the edge processing algorithm for the image is a common computer algorithm for recognizing object edges in existing technology, and its specific processing principle will not be elaborated here). The edge of the motor lamination is acquired and processed, and compared with a standard motor lamination image. When the overall error of each comparison point is within 1% (this error range can be adjusted according to the actual situation), the motor lamination is judged to be qualified. If it exceeds the error range, the motor lamination is judged to be unqualified. This can fully detect and judge the motor lamination, and the vertical setting effectively ensures the accuracy of the detection.

[0038] Further, please refer toFigures 1-5 The direction in which the motor laminations supported by the enclosed plate 41 descends is along the straight line of the positioning line and away from the detection groove 21. A drive frame 44 is provided on the outside of the enclosed plate 41. A lifting drive rail 441 is provided on one side of the drive frame 44. A limit rail is provided on the side of the drive frame 44 away from the lifting drive rail 441. The movable block of the lifting drive rail 441 is rotatably connected to the enclosed plate 41. The lifting drive rail 441 drives the enclosed plate 41 to move up and down under the limit of the limit rail through the movable block.

[0039] The bottom end of the enclosed plate 41 is provided with a driven shaft 411. One end of the driven shaft 411 is rotatably connected to the movable block of the lifting drive rail 441, and the other end of the driven shaft 411 is provided with a connecting pin groove 412. The bottom end of the drive frame 44 away from the lifting drive rail 441 is also provided with a rotary drive motor 442. When the enclosed plate 41 moves to the bottom end of the drive frame 44, the drive pin of the rotary drive motor 442 can be embedded in the connecting pin groove 412.

[0040] The limiting track includes a lifting track 443 and a rotating track 444. A limiting block 413 is fixedly provided at one end of the enclosed plate 41 near the limiting track, and the limiting block 413 is limited inside the limiting track. During the lifting and lowering process of the enclosed plate 41 driven by the lifting drive guide rail 441, the limiting block 413 can only move up and down under the limitation of the lifting track 443. Under the drive of the lifting drive guide rail 441, the limiting block 413 moves into the rotating track 444, and the limiting block 413 can rotate under the restriction of the rotating track 444.

[0041] When the enclosed plate 41 moves to the bottom of the drive frame 44, the limiting block 413 moves into the rotating track 444. At this time, the rotary drive motor 442 can drive the enclosed plate 41 to rotate around the driven shaft 411 through the engagement of the drive pin and the connecting pin groove 412. When the motor lamination is qualified, the rotary drive motor 442 drives the enclosed plate 41 to rotate forward and point towards the good product channel 42, guiding the motor lamination supported by the enclosed plate 41 to the good product channel 42. When the motor lamination is unqualified, the rotary drive motor 442 drives the enclosed plate 41 to rotate in the reverse direction and point towards the defective product channel 43, guiding the motor lamination supported by the enclosed plate 41 to the defective product channel 43.

[0042] Therefore, during use, after the detection mechanism 3 completes the detection of the motor lamination inside the detection groove 21, the lifting drive rail 441 drives the closed plate 41 to move. Since the limiting block 413 can only move up and down under the limitation of the lifting rail 443, the closed plate 41, driven by the lifting drive rail 441, can only move downwards along the straight line of the positioning line and away from the detection groove 21 until the closed plate 41 moves to the lowest point limited by the lifting guide rail 441 (the bottom end of the drive frame 44), providing rotation space for the closed plate 41. At this time, the limiting block 413 moves into the rotation rail 444, and the drive pin of the rotation drive motor 442 can... Embedded inside the connecting pin groove 412, the rotary drive motor 442 can drive the closed plate 41 to rotate around the driven shaft 411 through the engagement of the drive pin shaft and the connecting pin groove 412. When the motor lamination is qualified, the rotary drive motor 442 drives the closed plate 41 to rotate forward and point towards the good product channel 42, guiding the motor lamination supported by the closed plate 41 to the good product channel 42. When the motor lamination is unqualified, the rotary drive motor 442 drives the closed plate 41 to rotate in the reverse direction and point towards the defective product channel 43, guiding the motor lamination supported by the closed plate 41 to the defective product channel 43, thereby separating the good and defective motor laminations and ensuring the yield rate of the final product.

[0043] Further, please refer to Figures 6-8 The central conveying mechanism 5 includes a guiding conveying unit 51 and a stacking separation unit 52. The guiding conveying unit 51 includes several conveying rollers 511 and two symmetrically arranged guide frames 512. The two guide frames 512 are mounted above the conveying rollers 511 and both guide frames 512 have inclined sections. During the conveying process of the several conveying rollers 511, the motor laminations are centrally conveyed along the conveying direction of the several conveying rollers 511 under the guidance of the inclined sections of the two symmetrically arranged guide frames 512. The stacking separation unit 52 includes two separation rollers 521. The minimum gap between the two separation rollers 521 is greater than the thickness of one motor lamination and less than the thickness of the two motor laminations. Among the centrally conveyed motor laminations, only one motor lamination can pass through the minimum gap between the two separation rollers 521.

[0044] The stacking and collecting mechanism 6 includes a transfer frame 61, a lifting drive assembly 62, and a transfer trolley 63. The lifting drive assembly 62 includes a lifting drive motor 621 and a drive screw 622. The transfer frame 61 and the drive screw 622 are threadedly engaged. The lifting drive motor 621 can drive the transfer frame 61 to lift by rotating the drive screw 622.

[0045] The motor laminations passing through the two separating rollers 521 are carefully conveyed by the separating rollers 521 to the inside of the transfer frame 61. For each additional motor lamination inside the transfer frame 61, the lifting drive motor 621 drives the transfer frame 61 to descend by the thickness of one motor lamination, until the transfer frame 61 descends to below the transfer plane of the transfer trolley 63, transferring all the motor laminations inside the transfer frame 61 to the inside of the transfer trolley 63.

[0046] Qualified motor laminations output from the tail end of the good product channel 42 first fall onto several conveyor rollers 511. During the conveying process, the motor laminations are guided by the inclined sections of two symmetrically arranged guide frames 512, and are conveyed centered along the conveying direction of the several conveyor rollers 511. Because the minimum gap between the two separating rollers 521 is greater than the thickness of one motor lamination but less than the thickness of two motor laminations, only one motor lamination conveyed centered can pass through the minimum gap between the two separating rollers 521. This eliminates the possibility of motor lamination stacking and prevents misalignment between motor laminations entering the stacking and collecting mechanism 6. The motor laminations are gradually stacked inside the transfer frame 61. For each additional motor lamination added inside the receiving frame 61, the lifting drive motor 621 drives the receiving frame 61 to descend by the thickness of one motor lamination, until the receiving frame 61 descends below the transfer plane of the transfer trolley 63, transferring all the motor laminations inside the receiving frame 61 into the transfer trolley 63, completing the collection of one set of motor laminations. After the set of motor laminations is transferred by the transfer trolley 63, the empty transfer trolley 63 is repositioned at its initial position. After the lifting drive motor 621 drives the receiving frame 61 to rise to its initial position, the collection process of the next set of motor laminations begins again. Thus, the qualified motor laminations are sorted by the central conveying mechanism 5, and the sorted motor laminations are neatly stacked by the stacking collection mechanism 6 for the subsequent packaging process.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
