Description

Technical Field

[0001] This invention relates to the field of automated inspection, and in particular to an automatic material handling and inspection machine for inspecting magnetic steel sheets. Background Technology

[0002] Currently, the devices on the market that detect magnetic steel sheets during chamfering use a special pendulum ring with measuring tools such as digital calipers and micrometers. The detection method requires workers to take out an appropriate amount of magnetic steel sheets from the chamfering machine, place them on a mold platform, and manually place the magnetic steel sheets one by one on the inner wall of the pendulum ring. Then, the gap size of the entire ring is measured by a feeler gauge to determine the chamfering time.

[0003] The above method has at least the following technical problems: First, the manual ring-spinning inspection method requires workers to repeatedly place the magnetic steel sheets for a long time, which is labor-intensive and leads to excessive inspection time, reduced efficiency, and thus increased costs. Second, the manual ring-spinning inspection uses digital calipers and micrometers to measure the results by visual inspection, and the manual placement of the magnetic steel sheets onto the ring is prone to errors in the placement of individual magnetic steel sheets, resulting in inconsistent accuracy and cumulative angle errors, which can easily cause confusion in the test results. Since one of the uses of the test results is to determine the chamfering time of the magnetic steel sheets, inaccurate chamfering time will lead to a large number of defective products. Third, since the chamfering machine needs to hold about 8,000 products during the chamfering process, the manual ring-spinning inspection can only perform a small-scale sampling inspection and cannot test all samples, which will inevitably affect the general applicability of the test results and thus increase the occurrence rate of defective products.

[0025] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0026] The present invention addresses the problems of low accuracy, low efficiency, and low final product qualification rate in the manual arranging test of magnetic steel sheets in the prior art. It provides an automated testing solution that performs testing before the magnetic steel sheets enter the chamfering machine and during the chamfering process. Due to the automated transmission method, the machine eliminates the unavoidable errors of manual placement during testing, improving accuracy. Because of the electrical control, the automatic material placement and testing machine can maintain stability during high-speed operation, improving testing efficiency. The combination of automated transmission and electrical control achieves full coverage of sample testing on industrial magnetic steel sheets, eliminating the possibility of defective products entering the market without testing, increasing the qualification rate, and freeing up workers' time.

[0027] In order to solve the above-mentioned problems in the prior art, the inventors of this invention have invented an automatic magnetic steel sheet placement and inspection machine through creative work.

[0028] Example 1:

[0029] This embodiment provides an automatic material placement and inspection machine, such as... Figures 1 to 5As shown, the system includes a transmission mechanism, comprising a conveyor belt and a flipping device for conveying and flipping magnetic steel sheets; a pushing and discharging mechanism, comprising a pushing cylinder and a sliding cylinder, wherein the input end of the pushing and discharging mechanism receives the magnetic steel sheets conveyed by the transmission mechanism, and the pushing cylinder and the sliding cylinder are linked to push the magnetic steel sheets out; a placement platform, the placement platform being an overall annular structure, the inner wall of the placement platform receiving the magnetic steel sheets conveyed by the pushing and discharging mechanism for placing the magnetic steel sheets and providing detection conditions; and a detection mechanism, comprising a magnetic scale and a positioning block, the magnetic scale and the positioning block being mechanically fixed for detecting the magnetic steel sheets.

[0030] The receiving mechanism includes multiple feeding cylinders and a receiving bin. The feeding cylinders are fixed to the material placement platform and are used to feed the magnetic steel sheet into the receiving bin.

[0031] The existing method of manually oscillating the magnetic steel sheets during the chamfering or beveling process cannot fully cover a large number of magnetic steel sheets. This method is inefficient, inaccurate, increases workers' labor time, and leads to a low finished product qualification rate.

[0032] Specifically, to achieve automated detection of magnetic steel sheets and eliminate the drawbacks of manual ring-swing detection, this embodiment provides an automatic material handling and detection machine. The overall structure of the automatic material handling and detection machine includes a feeding mechanism 7, a transmission mechanism 1, a pushing and discharging mechanism 2, a material handling platform 3, a detection mechanism 4, and a receiving mechanism 5. The feeding mechanism 7 periodically outputs individual magnetic steel sheets, feeding the randomly poured magnetic steel sheets evenly and continuously. The transmission mechanism 1 receives the flat magnetic steel sheets conveyed by the feeding mechanism and flips the magnetic steel sheets into an upright position to be transmitted to the pushing and discharging mechanism 2. The sliding cylinder 22 in the pushing and discharging mechanism 2 reciprocates, driving the sliding pushing plate 222. The sliding pushing plate 222 pushes the magnetic steel sheets along the tangent of the inner wall of the positioning ring 31 of the material handling platform 3 into the material handling platform 3. The reciprocating motion direction of the vertically placed magnetic steel sheet is perpendicular to that of the slide cylinder 22. The flipped vertical magnetic steel sheet is pushed into the slide cylinder 22 by the pushing cylinder 21 of the pushing and feeding mechanism 2. Then, the slide cylinder 22 hits the magnetic steel sheet tangentially into the inner wall of the annular positioning ring 31. The magnetic steel sheet is fixed by magnetic adsorption by the inner wall of the positioning ring 31. The magnetic steel sheet that enters later pushes the magnetic steel sheet that entered earlier until it is close to the positioning block 42 in the detection mechanism 4 and pushes it a certain distance. The magnetic grid ruler 41 in the detection mechanism 4 detects and records the pushing distance. The cumulative error of the magnetic steel sheet is obtained by comparing it with the theoretical distance. A receiving bin is set below the material placement platform. The receiving bin receives the magnetic steel sheet knocked down by the receiving mechanism 5. When the automatic material placement detection machine finishes detection, the feeding cylinders 51 of multiple receiving mechanisms 5 push the magnetic steel sheet into the receiving bin for further turnover.

[0033] In this embodiment, the existing magnetic steel sheet needs to be placed in close contact with the motor rotor. The surface of each magnetic steel sheet has a certain curvature. In this embodiment, "vertical placement" means that the longest side of the magnetic steel sheet is placed vertically relative to the ground. Since the detection requires the magnetic steel sheet to be vertical, but vertical placement has low stability and is easy to tip over, horizontal placement is used in some transmission processes to maintain stability. "Horizontal placement" means that the longest side of the magnetic steel sheet is parallel to the ground, the convex side faces downward, and points in the specific transmission direction. The description of horizontal and vertical placement in the embodiments is not intended to limit the invention to the precise form disclosed, but rather to disclose one implementation method so that those skilled in the art can understand it, and many changes can be made according to the undescribed but deducible ways or other implementations of the invention.

[0034] Based on the above scheme, the detection of the magnetic steel sheet before or during the chamfering process in this embodiment is as follows: The magnetic steel sheet is fed horizontally by the feeding mechanism 7 to the transmission mechanism 1. The transmission mechanism 1 flips the magnetic steel sheet into an upright position and transmits it to the pushing and feeding mechanism 2. The upright magnetic steel sheet is fed into the stacking platform 3 by the pushing and feeding mechanism 2 and the detection is completed. The tested magnetic steel sheet is then fed into the receiving bin by the receiving mechanism 5.

[0035] This embodiment provides a machine that automatically transports, places, and detects magnetic steel sheets, thereby increasing detection efficiency, improving accuracy, and ultimately increasing the product qualification rate.

[0036] In a preferred embodiment of this invention, the feeding mechanism 7 is used to accommodate the magnetic steel sheet and deliver it to the transmission mechanism 1 in an orderly manner.

[0037] Specifically, in order to orderly deliver the magnet sheets to the input end of the transmission mechanism, such as... Figure 1 As shown, the feeding mechanism 7 can be a feeder or a screening machine. The feeder can be a vibratory feeder or a plate feeder. In a preferred embodiment, the feeding mechanism 7 is a vibratory feeder, which includes a vibratory feeder 71. The vibratory feeder 71 has a bowl-shaped structure, with a conveying channel spiraling upwards along the inner wall of the vibratory feeder and hinged thereto. A discharge channel is located at the highest point of the conveying channel, with one end connected to it and the other end serving as the discharge port. When the magnetic steel sheets are poured into the feeder, the machine starts, and the vibratory feeder 71 vibrates while rotating periodically. Centrifugal force drives the magnetic steel sheets into the conveying channel. The conveying channel rotates coaxially with the vibratory feeder 71, driving the magnetic steel sheets into the discharge channel. Magnetic steel sheets behind the channel push the magnetic steel sheets in front of them out of the discharge port. By periodically outputting individual magnetic steel sheets, the feeder uniformly and continuously feeds the randomly poured magnetic steel sheets, meeting the stability and continuity requirements of subsequent mechanisms processing large quantities of magnetic steel sheets.

[0038] In a preferred embodiment of this invention, the transmission mechanism 1 specifically includes: a conveyor belt device 11 comprising a conveyor belt 111 and at least two pulleys 112, the conveyor belt 111 being sleeved on the pulleys 112, the feed end of the conveyor belt 111 receiving externally conveyed magnetic steel sheets, and the output end of the conveyor belt 111 forming a first arc 113 at the position of the pulleys 112; a flipping device 12 comprising a flipping conveyor belt 121, a portion of the flipping conveyor belt 121 being attached to the first arc 113 position of the conveyor belt 111 to form a second arc 124; the flipping conveyor belt 121 moving synchronously with the conveyor belt 111, the first arc 113 position of the conveyor belt 111 and the second arc 124 position of the flipping conveyor belt 121 forming a material channel, the feed end of the material channel being horizontal and the discharge end being vertical, and the magnetic steel sheets passing through the material channel achieving an attitude angle flip.

[0039] Specifically, existing conveyor belts only have one conveying direction and cannot rotate the magnetic steel sheets from a horizontal position to an upright position. To achieve automated conveying and rotating of the magnetic steel sheets, this preferred embodiment includes a transmission mechanism 1, such as... Figure 1 and Figure 2 As shown, the transmission mechanism 1 includes a conveyor belt device 11 and a turning device 12. The conveyor belt device 11 further includes a conveyor belt body 111 and at least two pulleys 112, one or more of which are powered. The conveyor belt 111 is fitted onto the pulleys 112, making the conveyor belt 111 rounded rectangular in shape, and rotates with the powered pulleys. The feed end of the conveyor belt 111 abuts against the discharge channel of the feeding mechanism 7, receiving the magnetic steel sheets conveyed by the feeding mechanism 7. The function of the conveyor belt 111 is to move the magnetic steel sheets from the feed end to the output end, and to turn the magnetic steel sheets with the turning conveyor belt 121, so that the magnetic steel sheets change from flat to upright. The output end of the conveyor belt 111 forms a first arc 113 at the rounded corner of the rectangular shape of the pulley 112.

[0040] Multiple drive wheels 122 and driven wheels 123 adjust their positions to change the shape of the flipping conveyor belt 121, forming a second arc 124 at the rounded corner of the conveyor belt 111. The middle part forms a material channel to prevent the magnetic steel sheet from falling off the predetermined track due to inertia during the flipping process. The magnetic steel sheet passes through the space between the first arc 113 and the second arc 124 of the material channel. The first arc 113 of the conveyor belt 111 and the second arc 124 of the flipping conveyor belt 121 rotate in the same direction, driving the magnetic steel sheet from a flat posture to a vertical posture by rotating 90° or setting the rotation angle according to actual needs.

[0041] In this embodiment, the transmission mechanism changes the conveying direction of the magnetic steel sheet and its posture by setting a flipping device, so that it changes from a flat position to an upright position, which facilitates the placement for subsequent testing, and the flipping effect is good, making it less likely for the magnetic steel sheet to fall out.

[0042] In a preferred embodiment of this invention, the flipping device 12 further includes: one or more drive wheels 122, which are driven by a motor to obtain rotational power; one or more driven wheels 123, which are rotated along with the rotational power; the flipping conveyor belt 121 is sleeved on the plurality of drive wheels 122 and driven wheels 123, the drive wheels 122 drive the flipping conveyor belt 121 to rotate synchronously with the conveyor belt 111, and the rotation of the flipping conveyor belt 121 drives the driven wheels 123 to rotate; the magnetic steel sheet passes through the space between the first arc 113 and the second arc 124 of the material channel, and is flipped from a flat posture to an upright posture by rotating 90°.

[0043] Specifically, in this embodiment, in order to realize the second arc shape 124 and drive the second arc shape 124 to rotate, a flipping device 12 is provided, such as... Figure 1 and Figure 2 As shown, the tilting device 12 is located at the first arc. The tilting device 12 includes one or more driving wheels 122, one or more driven wheels 123, a tilting conveyor belt 121, and a second arc 124. The tilting conveyor belt 121 is sleeved on the multiple driving wheels 122 and driven wheels 123. The driving wheels 122 are sleeved on a transmission rod, which is driven by a motor to rotate, thus driving the driving wheels 122 to rotate. This gives the driving wheels 122 power, and the rotation of the driving wheels 122 drives the tilting conveyor belt 121, which in turn drives the driven wheels 123 to rotate. The multiple driving wheels and driven wheels... By adjusting the position, the shape of the flipping conveyor belt 121 is changed, and a second arc 124 is formed at the rounded corner of the rounded rectangle of the conveyor belt 111. The middle is sandwiched to form a material channel. The magnetic steel sheet is sandwiched between the first arc 113 and the second arc 124 of the material channel. When the automatic material handling and detection machine is started, the first arc 113 of the conveyor belt 111 and the second arc 124 of the flipping conveyor belt 121 rotate in the same direction, clamping and driving the magnetic steel sheet from a flat posture to a vertical posture by rotating 90° or setting the rotation angle according to actual needs, and falling off at the output end of the material channel due to gravity.

[0044] In this embodiment, the flipping conveyor belt 121 is erected by the driving wheel 122, the driven wheel 123 and the first arc support to form the second arc 124, and can rotate in the same direction as the first arc 113 to complete the flipping of the magnetic steel sheet from a flat position to an upright position, and the flipping effect is good.

[0045] In a preferred embodiment of this invention, the material placement platform 3 includes: a positioning ring 31, which is annular in shape, with an opening channel 311 located on the tangent of the inner wall of the positioning ring 31, and the opening channel 311 connected to the output end of the material pushing and feeding mechanism at the outer wall end of the positioning ring 31; and a plurality of soft magnetic strips 32, which are fixed around the inner wall of the positioning ring 31, with the starting end of the soft magnetic strips 32 connected to the inner wall end of the opening channel.

[0046] Specifically, in order to place the magnetic steel sheet into the placement platform, in this embodiment, the placement platform 3 is provided with an opening channel 311 based on the tangent position of the inner wall of the annular positioning ring 31 for the magnetic steel sheet to enter, such as... Figure 1 and Figure 4 As shown, the opening channel 311 serves as a feed inlet on the outer wall of the positioning ring 31. Multiple soft magnetic strips 32 are arranged on the inner wall of the positioning ring 31. The starting end of each soft magnetic strip 32 is connected to the inner wall of the opening channel 311. The soft magnetic strips wrap around the inner wall of the positioning ring 31 once, and their ends are movably connected to the positioning block 42 in the detection mechanism 4. The soft magnetic strips 32 can magnetically attract the magnetic steel sheet to the inner wall of the positioning ring 31. Simultaneously, their smooth surface allows the magnetic steel sheet to move along the soft magnetic strips 32. When the automatic material handling and detection machine is running, the magnetic steel sheet enters the opening channel 311 along the tangent of the positioning ring 31, encounters the soft magnetic strip 32 at the tangent point, and is magnetically attracted to the soft magnetic strip 32 along the inner wall of the positioning ring 31. The process involves circling the magnetic steel sheets. Assuming the chamfering is acceptable, the theoretical number of magnetic steel sheets needed to reach the positioning block 42 in a full circle is calculated and set as a predetermined quantity. When this predetermined number of magnetic steel sheets circulates the inner wall of the positioning circle, if the chamfering is unacceptable, the resulting burr defects increase the length of the magnetic steel sheets in a full circle, causing the positioning block 42 of the detection mechanism to move a certain distance. The magnetic scale follows the positioning block 42 and measures the distance moved, i.e., the error. By comparing the error with the preset value, a professional worker can calculate the required chamfering time without manual measurement, reducing labor. If the chamfering is acceptable and the error is within an acceptable range, subsequent chamfering time can be omitted based on the detection results, increasing efficiency.

[0047] The inventive concept of this embodiment is as follows: First, by setting a positioning ring 31, multiple magnetic steel sheets are simulated to be placed on the inner wall of the motor rotor and tested, which realizes the effect of magnifying the error of the rough edges of a single magnetic steel sheet, and can intuitively discover the defects of the magnetic steel sheet; Second, the opening platform 31 in the positioning ring 31 receives the magnetic steel sheets pushed in by the pushing and feeding mechanism 2, and the machine action has high precision, which can reduce the error caused by manual testing.

[0048] This embodiment reduces the useless cumulative error caused by inaccurate manual placement by setting a positioning ring and using mechanical pushing of the magnet sheet, and amplifies the useful cumulative error caused by the defective magnet sheet itself, resulting in more accurate test results.

[0049] In a preferred embodiment of this invention, the feeding mechanism 2 includes a sliding cylinder 22 and a pushing cylinder 21. The sliding cylinder 22 includes a sliding cylinder body 221 and a sliding pushing plate 222, the pushing plate 222 being fixed to the cylinder arm of the sliding cylinder body 221, and having a groove. The pushing cylinder 21 includes a pushing cylinder body 211 and a pushing cylinder adjusting plate 212, the adjusting plate 212 being fixed to the cylinder arm of the pushing cylinder body 211. The reciprocating motion directions of the sliding cylinder 22 and the pushing cylinder 21 are perpendicular, and the pushing cylinder 21 reciprocates towards the groove of the sliding pushing plate 222.

[0050] Specifically, in order to automatically push the magnetic steel sheet into the positioning ring, this embodiment sets up a pushing and feeding mechanism 2, such as... Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the feeding mechanism 2 includes a feeding cylinder 21 and a sliding cylinder 22. The sliding cylinder 22 includes a sliding cylinder body 221 and a sliding pusher plate 222. The sliding cylinder body 221 includes a power mechanism and a cylinder arm. The cylinder arm is driven by the power mechanism and reciprocates within a certain stroke. The cylinder arm of the sliding cylinder body 221 fixes the sliding pusher plate 222. The sliding pusher plate 222 is driven by the cylinder arm of the sliding cylinder body 221. The sliding pusher plate 222 can extend the stroke of the cylinder arm of the sliding cylinder body 221. The sliding pusher plate 222 is provided with a groove for temporarily storing the magnetic steel sheet pushed by the feeding cylinder 21. When the magnetic steel sheet is pushed into the groove, the sliding cylinder pushes the magnetic steel sheet into the inner wall of the positioning ring 31 along the opening channel.

[0051] The pusher cylinder 21 includes a pusher cylinder body 211 and a pusher cylinder adjusting plate. The pusher cylinder body 211 includes a power mechanism and a cylinder arm. The cylinder arm is driven by the power mechanism and reciprocates within a certain stroke. The cylinder arm of the pusher cylinder body 211 is fixed to one end of the pusher cylinder adjusting plate 212. The discharge port of the vertical material channel 8 of the transmission mechanism 1 is aligned with the other edge of the pusher cylinder adjusting plate 212. The pusher cylinder adjusting plate 212 can adjust its size according to the size of the magnetic steel sheet. When the pusher feeding mechanism is started, firstly... Adjust the pusher cylinder adjustment plate 212 to match the size of the current magnetic steel sheet. The magnetic steel sheets conveyed by the transmission mechanism 1 are stacked in the vertical material channel 8. When the bottom magnetic steel sheet is on the edge of the pusher cylinder adjustment plate 212, the pusher cylinder body 211 drives the pusher cylinder adjustment plate 212 to retract, and a single magnetic steel sheet falls in the direction of movement of the pusher cylinder adjustment plate 212. At this time, the pusher cylinder pushes the pusher cylinder adjustment plate 212 to move the magnetic steel sheet to the groove of the slide pusher plate 222, and then the slide pusher plate 222 pushes the magnetic steel sheet into the positioning ring 31 along the positioning ring opening channel 311.

[0052] The purpose of the pusher cylinder body 211 is to provide a buffer zone for the magnetic steel sheets entering the loading platform 3. In the event of an emergency stop of the automatic loading and testing machine, the pusher cylinder body 211 can be shut down first, followed by the automatic loading and testing machine. Once the pusher cylinder body 211 stops working, subsequent mechanisms will no longer accept magnetic steel sheets. The magnetic steel sheets transported by the transmission mechanism will be stacked in the vertical material channel 8, preventing them from jamming or falling out of their predetermined positions. This protects the entire automatic loading and testing machine from damage and reduces the risk of failure. The purpose of setting the pusher cylinder 21 with the pusher cylinder adjustment plate 212 is that the pusher cylinder adjustment plate 212 can be adjusted according to the size of the magnetic steel sheet to adapt to the detection of different types of magnetic steel sheets; in the transmission mechanism 1, the multiple magnetic steel sheets stacked in the vertical material channel fall on the pusher cylinder adjustment plate. When it is necessary to push a single magnetic steel sheet, the cylinder arm drives the pusher cylinder adjustment plate 212 to retract, and the bottom magnetic steel sheet falls on the pusher cylinder adjustment plate at the pushable position. This can ensure the stability of the magnetic steel sheet stacking and prevent the magnetic steel sheet from falling out of the predetermined position.

[0053] The pusher cylinder works in conjunction with the slide cylinder to ensure smooth, periodic cycling, preventing the magnetic steel sheet from getting stuck or falling out of its predetermined position.

[0054] In a preferred embodiment of this invention, the detection mechanism 4 specifically includes: a sliding table, comprising a fixed plate and a sliding plate, the sliding plate being movably connected to the fixed plate, and the fixed plate being fixed to the positioning ring; a positioning block, the positioning block being fixedly connected to the sliding plate, the positioning block abutting against the end of the soft magnetic strip, wherein when the magnetic steel sheet is fully positioned along the soft magnetic strip, a defective magnetic steel sheet will cause the total length of the magnetic steel sheet to exceed the expected length, and the excess portion will push the positioning block; and a magnetic scale, the magnetic scale being fixedly connected to the positioning block, the magnetic scale measuring displacement.

[0055] Specifically, to achieve automated testing, this embodiment includes a testing mechanism 4, please refer to... Figure 1 and 4 The detection mechanism 4 includes a slide table, comprising a fixed plate 431, a sliding plate 432, and a linear slide rail 433. The fixed plate 431 is fixedly connected to the positioning ring 31, the linear slide rail 433 is mounted on the fixed plate 431, and the sliding plate 432 is slidably fixed to the linear slide rail 433, allowing it to move along the tangential direction of the end of the soft magnetic strip 32. A compression spring is provided, with its two ends connected to the fixed plate 431 and the sliding plate 432 respectively, assisting in adjusting the position of the sliding plate. A magnetic scale 41 and a positioning block 42 are fixed on the sliding plate, and the magnetic scale 41 can detect and record the movement distance. Before actual detection, the position of the sliding plate 432 on the slide rail is adjusted, and the positioning block 42 is close to the end of the soft magnetic strip 32. Assuming the chamfer of the magnetic steel sheet is qualified, the theoretical calculation shows that it can theoretically fill a circle. The number of magnetic steel sheets that can contact the positioning block 42 is a predetermined quantity. When the system starts, the predetermined number of magnetic steel sheets rotate once around the inner wall of the positioning ring. If the specifications and dimensions of the magnetic steel sheets are not up to standard, the burr defects increase the length of the magnetic steel sheets to fill the ring, causing the positioning block 42 of the detection mechanism to move a certain distance. The magnetic scale follows the positioning block 42 and measures the moving distance, i.e., the error. By comparing the difference between the error and the preset value, professional workers can calculate the required chamfering time based on this difference without manual measurement, reducing the labor of workers. When the chamfering of the magnetic steel sheets is qualified and the difference is within an acceptable range, the subsequent chamfering time can be saved based on the test results, increasing efficiency. Since the position of the testing mechanism in this embodiment is adjustable, it can measure magnetic steel sheets of different specifications.

[0056] In a preferred embodiment of this invention, the material receiving mechanism 5 includes: a plurality of feeding cylinders 51 fixed on the positioning ring 31; a feeding cylinder connecting plate 52 disposed on a layer on the inner wall of the positioning ring 31 and movably connected to the positioning ring 31, wherein the feeding cylinder connecting plate 52 is fixed on the cylinder arm of the feeding cylinder 51.

[0057] Specifically, in order to ensure that the magnetic steel sheet on the positioning ring 31 can detach from the soft magnetic strip 32 on the inner wall of the positioning ring 31 after detection, this embodiment provides a receiving mechanism 5. Please refer to... Figure 1 and Figure 4 The receiving mechanism 5 includes three feeding cylinders 51 and feeding cylinder connecting plates 52. The feeding cylinders 51 are equidistantly fixed on the positioning ring 31, and the cylinder arms reciprocate towards the center of the positioning ring. The feeding cylinder connecting plates 52 are fixed on the cylinder arms of the feeding cylinders 51 and are positioned on a layer inside the positioning ring 31. A clamp-like structure is movably connected to the inner wall of the positioning ring 31, close to the placement position of the magnetic steel sheets. When one ring of magnetic steel sheets has been tested, the feeding cylinder connecting plate 52, driven by the feeding cylinders 51, pushes the magnetic steel sheets away from the soft magnetic strip 32, separating all the magnetic steel sheets adsorbed on the positioning ring 31 from the positioning ring 31 in one go. The sheets then fall from the inner wall of the positioning ring 31 into a receiving bin below. This design allows for rapid unloading, facilitating the placement of subsequent magnetic steel sheets on the positioning ring 31 and improving efficiency.

[0058] In a preferred embodiment of this invention, the transmission mechanism further includes a drying mechanism 6, which is mounted on the side of the conveyor belt 111 in the transmission direction and is used to dry water stains on the surface of the magnetic steel sheet.

[0059] Specifically, since the newly manufactured magnet sheets have water stains on their surface, which affects subsequent testing, this preferred embodiment provides a drying mechanism 6 to dry the water stains on the magnet sheet surface. The drying mechanism 6 can employ hot-cooling, air-cooling, a combination of hot and air, or other drying methods. When using air-cooling, please refer to... Figure 1 and Figure 2 The air-cooling mechanism is mounted on both sides of the conveyor belt 111. The mechanism has multiple cover plates 61 and multiple air supply pipes 62. The cover plates are located at both ends of the straight section of the conveyor belt 111. Magnets are transported along channels formed at intervals between the cover plates 61. The air supply pipes 62 are fixed to the cover plates 61, with one end aligned with the position where the magnets pass on the conveyor belt 111, and the other end receiving gas from the fan. When the magnets pass through the cover plates 61 of the air-cooling mechanism, the fan is turned on, activating the power air supply. The power air is blown onto the magnets through the air supply pipes 62, drying any water stains adhering to the product surface. Because the air-cooling mechanism of this invention uses multiple air supply pipes 62, drying efficiency is ensured, and the influence of water stains on the test results is prevented.

[0060] In a preferred embodiment of this invention, the transmission mechanism 1 further includes a vertical material channel 8, which is disposed between the output end of the transmission mechanism 1 and the pusher cylinder adjustment plate 212. The vertical material channel 8 includes a positioning groove 81 and multiple pressure plates 82: the multiple pressure plates are pressed to form a vertical material channel; the positioning groove is located at one section of the vertical material channel, and the positioning groove has a detection head inside, which is aligned with the position where the magnetic steel sheet passes.

[0061] Specifically, in order to achieve stacking and storage of magnetic steel sheets, this preferred embodiment provides a vertical material placement channel, such as... Figure 1 and Figure 5 As shown, the vertical material channel 8 is located between the output end of the transmission mechanism 1 and the adjusting plate 212 of the pusher cylinder. It includes a positioning groove 81 and multiple pressure plates 82. The multiple pressure plates 82 squeeze out a long, flat cubic space with multiple magnets of different heights and dimensions that fit the vertical dimensions of the magnets, forming the vertical material channel 8 channel for magnets. Some magnets can be stacked vertically and stored in the vertical material channel 8 channel. The positioning groove 81 is located on the pressure plate 82 and is equipped with a sensor. The sensor detection head is aligned with the position of the magnets passing through the vertical material channel 8 channel to detect the number of magnets remaining in the vertical material channel 8 channel.

[0062] The purpose of setting up the vertical material channel 8 is to stack the magnetic steel sheets to prevent them from falling too high and causing damage, and to stabilize the stacked magnetic steel sheets to prevent them from falling out of the predetermined track. The function of setting up the positioning groove 81 is to adjust the speed of the incoming magnetic steel sheets based on the number of stacked magnetic steel sheets detected, so as to ensure that there is a predetermined number of magnetic steel sheets in the vertical material channel 8.

[0063] Specifically, when the automatic material handling and testing machine is shut down in an emergency, the vertical material channel 8 acts as a buffer for the magnetic steel sheets. The positioning slot 81 counts the number of magnetic steel sheets accumulated in the vertical material channel 8. After the automatic material handling and testing machine is restarted, the pushing cylinder 21 first pushes the accumulated magnetic steel sheets to the subsequent mechanism for clearing, and then the electrical control mechanism starts the feeding mechanism 7, allowing the entire automatic material handling and testing machine to operate normally. The vertical material channel 8 allows the automatic material handling and testing machine to be paused and restarted at any time without requiring additional breakpoint recovery time.

[0064] In a preferred embodiment of this invention, the flipping mechanism further includes one or more spring sliders 13, and one or more driven wheels 123 are mounted on the spring sliders 13. The spring sliders 13 include: a fixed plate, a slide rail, a spring, and a sliding plate. The fixed plate is mechanically fixed to the conveyor housing, the slide rail is connected to the fixed plate, the axis of the spring is parallel to the sliding direction of the slide rail, and one end is mechanically connected to the fixed plate. The sliding plate acts as a slider of the slide rail, connecting the other end of the spring and being fixed to the driven wheel 123. Since the flipping conveyor belt is easily damaged, the spring sliders 13 can move the rotating shaft of the flipping mechanism, thereby causing the flipping conveyor belt to detach for easy replacement.

[0065] In a preferred embodiment of this invention, the pushing cylinder 21 has a cylinder stroke and detection mechanism 23, including an auxiliary slider 231, a proximity switch 232, and a counting switch 233, as shown below. Figure 3As shown, the auxiliary slider 231 is mechanically fixed to the side of the cylinder arm of the pusher cylinder body 211 and moves together with the cylinder arm. The proximity switch 232 and the counting switch 233 are located at the maximum stroke of the auxiliary slider 231, with a certain distance between the two switches. The proximity switch 232 is electrically connected to the pusher cylinder 21. When the pusher cylinder 21 pushes the magnetic steel sheet, each time it reaches the maximum stroke, the auxiliary slider 231 presses down the proximity switch 232 and the counting switch 233. The proximity switch 232 controls the cylinder arm of the pusher cylinder 21 to move in the opposite direction, and the counting switch 233 records the increase in the number of pushed magnetic steel sheets. The proximity switch 232 can move within the stroke of the pusher cylinder. By adjusting its position, the maximum stroke of the pusher cylinder can be controlled, and the pushing stroke required for magnetic steel sheets of different sizes can be adjusted.

[0066] In a preferred embodiment of this invention, the slide cylinder 22 further includes a precision slide, which is fixed on the slide cylinder body 221 and is used to finely adjust the position of the slide cylinder 22.

[0067] Specifically, such as Figure 3 and Figure 4 As shown, the slide cylinder 22 includes a precision slide 24, which comprises an internal transmission structure, a slide rail, and a control handle. The slide cylinder 22 is fixed on the precision slide 24. The control handle moves the precision slide 24 through the internal transmission structure, causing the slide cylinder 22 to move precisely in the pushing direction of the pusher cylinder 21. To ensure that magnets of different sizes can enter the correct position on the slide cylinder pusher plate in this embodiment and be correctly pushed into the positioning ring 31, the position of the precision slide is precisely adjusted to solve the problem of excessively large or small spacing between adjacent pushes of magnets, preventing magnet jamming.

[0068] In a preferred embodiment of this invention, the automatic material handling and testing machine further includes an electrical control mechanism electrically connected to multiple mechanisms or devices within the automatic material handling and testing machine. This mechanism includes: a hardware circuit that controls the operation of each module through a software program and simultaneously receives test data; and a touch screen electrically connected to the hardware circuit.

[0069] Specifically, in order to coordinate the operation of the automatic material handling and inspection machine and assist professionals in its control, the automatic material handling and inspection machine also has an electrical control mechanism, which includes a touch screen and hardware circuitry. The hardware circuitry is electrically connected to each device of the automatic material handling and inspection machine, and is used to receive signals from the sensors and send command signals. Each device executes corresponding actions according to the commands to complete the inspection process. The touch screen is electrically connected to the hardware circuitry and is used to display sensor readings and control the hardware circuitry by clicking. The touch screen has multiple virtual buttons.

[0070] One of the buttons is the power button for the automatic material handling and testing machine. After powering on, the electrical control mechanism checks the breakpoint. If there are accumulated magnetic steel sheets in the vertical material channel 8, the pushing cylinder 21 and the sliding cylinder 22 will operate first to push the buffered magnetic steel sheets to the material handling platform 3. When the number of magnetic steel sheets in the vertical material channel 8 decreases, the transmission mechanism 1 will preheat and run. Then the feeder will run, and the automatic material handling and testing machine will start normally. The operating speed of the automatic material handling and testing machine will be based on the speed memorized from the last run.

[0071] Another button is an emergency stop button. When pressed, the automatic material handling and detection machine operates in the following sequence: the pushing cylinder 21 stops, while the transmission mechanism 1 continues to deliver magnetic steel sheets, which are temporarily stored at the vertical material channel 8; the feeding mechanism 7 stops conveying; the transmission mechanism 1 pauses after conveying the magnetic steel sheets onto the conveyor belt 111; and the sliding cylinder 22 stops accepting magnetic steel sheets and stops operating. The purpose of stopping each mechanism in sequence is to prevent the automatic material handling and detection machine from continuing to transmit magnetic steel sheets when they are jammed, thus avoiding greater losses and reducing the failure rate.

[0072] The other set of buttons is the speed adjustment button for the automatic material handling and testing machine. It is used to adjust the speed of the transmission mechanism, the operating cycle of the material pushing and feeding mechanism, and adjust the material pushing cylinder adjustment plate to the thickness of the product to adapt to the testing of magnetic steel sheets of different specifications.

[0073] The touchscreen is also used to display the settings, necessary test data, and test results of the automatic material handling and testing machine.

[0074] The above description is only an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
