Description

TECHNICAL FIELD

[0001] The present application relates to a core processing equipment, more particularly, it relates to a core oil hole through detection equipment and a control method thereof. BACKGROUND

[0002] The oil hole is an important part of the core, and its main function is to promote the flow of cooling oil to achieve efficient heat dissipation. Specifically, the core will generate iron loss under the action of alternating magnetic field, and the above loss will be converted into heat. By providing the core oil hole, a channel is provided for the cooling oil to pass through the inside of the core lamination, so that the heat can be more effectively transferred to the cooling oil, enhancing the heat dissipation efficiency. The design of the oil hole is a key heat dissipation and loss suppression technology for the core, which can provide a flow channel for the cooling oil to penetrate the inside of the core, carry away the heat generated by the core loss, and effectively suppress harmful local eddy current loss caused by local damage of the lamination insulation, preventing local overheating.

[0003] In order to ensure the heat dissipation effect of the core, it is necessary to ensure the throughness of the core oil hole, so that the oil can circulate in the core. If the oil hole is not through, the cooling oil cannot pass through the hole, so that the heat in the core of this area cannot be effectively dissipated, resulting in local overheating, which will accelerate the aging of the insulation material, and even cause insulation breakdown, leading to failure or fire of the transformer.

[0004] At present, the Chinese patent with application number 202211737399.2 discloses a camshaft oil hole detection device, which mainly discloses a detection method for through oil holes, including a fixing unit and a detection unit. The fixing unit includes a main shaft, a tail seat and a pressing piece. The main shaft is opposite to the tail seat, and a high-pressure air channel is provided on the main shaft. The pressing piece is connected with the tail seat and used to push the tail seat towards the side close to the main shaft. The detection unit includes a fixed block and a paddle. The paddle is hinged to the fixed block. The camshaft oil hole detection device in the present application can detect whether the oil hole is through without using a steel ball, so as to improve the test efficiency and reduce the test risk. Although this method can detect multiple oil holes, the paddle needs to be reset after detection, which is low in detection efficiency and prone to misjudgment due to insufficient air pressure or paddle aging.

[0005] For example, Chinese patent application number 201310522503.0 discloses a valve sleeve oil hole detection method and mechanism. The method comprises a positioning seat for securing the valve sleeve, a CCD camera positioned above the positioning seat, the CCD camera connected to a PC, the PC connected to a monitor, and an illumination device mounted on the CCD camera. This valve sleeve oil hole detection mechanism uses image comparison to detect the oil holes on the inner circumference of the valve sleeve. The image of the oil hole on the inner circumference of the valve sleeve to be tested is compared with an image of the oil hole on the inner circumference of a standard valve sleeve. A computer program calculates the error between the two images to determine whether the oil holes on the inner circumference of the valve sleeve meet quality requirements. This detection method is simple, quick, highly accurate, and easy to use. It can be used to test batch products and effectively improve the detection accuracy of the oil holes on the inner circumference of the valve sleeve. Although the above method can detect clogged oil holes, it requires image extraction and image processing, which is a complicated step. Moreover, the detection result can only obtain the clogged oil holes. The iron core is formed by stacking multiple steel sheets, and the location of the blockage needs to be further detected, which is impossible to achieve with the above method. Summary of the Invention

[0008] The present invention is further configured as follows: a fixing rod is further provided on the mounting plate, and the fixing rod is configured to fix the iron core on the mounting plate.

[0009] The present invention is further configured as follows: a detection mechanism is also provided on the mounting bracket, the detection mechanism includes a baffle, a detection trough arranged on the baffle, and a plurality of infrared detection devices arranged on both sides of the baffle, and the detection range of the infrared detection device is configured to be distributed in a grid pattern on the top of the baffle.

[0010] Preferably, the size of the detection tank is R, and the size of the iron core is less than R and less than the size of the mounting plate.

[0011] The application is further provided with a lifting assembly at the bottom of the mounting bracket, which comprises a lifting plate, a pushing frame arranged at the lower end of the lifting plate, and a pushing motor arranged on the pushing frame.

[0012] The application is further provided with a feeding station and a detection station, and a transmission belt is arranged between the mounting bracket and the lifting mechanism, which is configured to drive the lifting mechanism to move on the mounting bracket.

[0013] The application is further provided with a quality detector arranged on the mounting groove, and a pressure sensor arranged at the top of the detection rod.

[0014] The application also provides a control method of the core oil hole penetration detection device, which comprises the following steps: S1, the lifting mechanism moves to the feeding station and remains stationary, while the quality detector detects the mass in the mounting groove; if the quality detector detects an increase in the mass, it is determined that the current core feeding is completed, and the step S2 is continued; otherwise, it is determined that the core is not fed;

[0015] S2, the transmission belt drives the lifting mechanism that has completed feeding to move to the detection station, the lifting assembly at the detection station pushes the lifting plate to move upward, the lifting plate lifts the bottom plate at the lifting mechanism, and the bottom plate and the mounting plate move to the baffle close to the detection mechanism;

[0016] S3, when the mounting plate moves to the detection groove of the detection mechanism, the core passes through the detection groove, the mounting plate and the baffle interfere with each other, the lifting assembly continues to push, and under the action of the buffer spring, the mounting plate moves to the direction close to the bottom plate, and the detection rod passes through the through hole on the mounting groove and enters the oil hole of the core;

[0017] S4, the infrared detection device detects whether there is an infrared signal; if yes, it is determined that the oil hole of the current core is penetrated, and the core is qualified; otherwise, it is determined that the oil hole of the current core is blocked, the detection rod lifts the core and blocks the infrared ray, the device stops working and notifies the staff to maintain.

[0018] Preferably, the step S4 further comprises a blocked oil hole detection method based on the infrared detection device, which comprises the following steps: S411, the infrared detection device detects the signal state; if the unilateral infrared detection device cannot detect the signal, it is determined that the unpenetrated oil hole is located close to the cross row or longitudinal row of the infrared detection device, and the subsequent staff is notified to detect the oil hole on this side;

[0019] S412, if the infrared detection device at the corner cannot detect the signal, it is determined that the unpenetrated oil hole is located close to the corner of the infrared detection device, and the subsequent staff is notified to detect the oil hole at the corner.

[0020] Preferably, the step S4 further comprises a clogged oil hole detection method based on the pressure sensor, comprising the following steps: S421, after the lifting assembly pushes the lifting mechanism, the pressure sensor at the top of each detection rod detects the pressure received thereby, if the pressure received by the pressure sensor at the top of each detection rod is 0, it is judged that the current iron core oil hole is through, and the iron core is qualified, otherwise, it is judged that there is a clogged oil hole, and jumping to S422 for position detection of the clogged oil hole;

[0021] S422, when there is a clogged oil hole, the detection rod detects the pressure received thereby, the detection value is P1, P2, P3, …, Px, and the detection rod receiving a pressure value > 0 is marked and recorded as an unpenetrated oil hole.

[0022] By adopting the above technical scheme, the beneficial effects are: 1. The present application forms an automatic high-precision oil hole penetration detection process through mechanical structure driving, sensor detection and algorithm judgment. Specifically, through the elastic buffer design of the lifting mechanism, the detection rod is in a retracted state in the installation groove when the iron core is not under pressure, and will not be exposed outside the through hole. The lifting assembly continuously jacks up the lifting mechanism, so that the lifting mechanism reaches the detection mechanism. Since the size of the iron core is smaller than the size of the detection groove, and the size of the detection groove is smaller than the size of the mounting plate, the iron core can pass through the detection groove. When the mounting plate is normally placed on the mounting plate, the infrared detection device is not blocked, and the lifting assembly continues to move. At this time, the mounting plate is attached to the bottom plate under the action of the baffle of the detection mechanism. The detection rod on the bottom plate passes through the through hole and enters the oil hole of the iron core. If the iron core oil hole is clogged, the detection rod lifts the iron core and blocks the signal of the infrared detection device. The automatic detection of the iron core is completed. After the detection is completed, the lifting assembly retreats to complete the reset. The overall process is simple, avoids the short-term shutdown caused by the manual reset of the dial piece, and detects the oil hole in real time through infrared sensing. No complex image processing is required. The detection method of the present application can accurately detect the position of the clogged oil hole and the depth position of the clogged position in the iron core based on the spatial layout of the infrared detection device and the detection value of the pressure sensor, providing extremely critical position information for subsequent maintenance or quality analysis, greatly improving the depth and value of the detection.

[0023] 2、Further, the application suspends the mounting plate above the bottom plate and sets a buffer spring between the mounting plate and the bottom plate, when the mounting plate is not pressed or is only pressed by the gravity of the core, the detection rod is in the through hole of the mounting plate, when the mounting plate is pressed by the stop plate and adheres to the bottom plate, the detection rod can penetrate the oil hole of the core, and the penetration of the oil hole is detected, specifically, when the lifting assembly pushes the bottom plate upward, the mounting plate first presses the stop plate of the detection mechanism, and the core penetrates the detection groove of the detection mechanism, the lifting assembly continues to push the bottom plate to compress the buffer spring, so that the detection rod can smoothly and controllably penetrate the through hole of the mounting plate and insert into the oil hole of the core, the buffer spring can provide a relatively smooth insertion force for the detection rod, preventing the detection rod from colliding with the blockage of the oil hole and causing damage, if the detection rod smoothly penetrates the oil hole, the core is normal, if there is a blockage, the blockage point will give pressure to the detection rod, and the core will block the signal of the infrared detection device, so as to judge that the oil hole is not penetrated, and if the pressure sensor on the top of the detection rod is used to detect the blockage state of the oil hole of the core, when the detection rod smoothly inserts into the oil hole, the sensor pressure is zero, if there is a blockage, the blockage point will exert pressure on the detection rod and be accurately sensed and recorded by the sensor, so that the blocked hole can be easily found, and since the core is formed by stacking a plurality of steel sheets with the same thickness, the pressure received by the detection rod can be based on the number of steel sheets, and since the mass of each steel sheet is the same, the number of lifted steel sheets can be determined based on the pressure received, so as to obtain the depth position of the blockage.

[0024] 3、Meanwhile, the application sets a plurality of infrared detection devices on both sides of the stop plate, the detection range of the infrared detection device is set to the top of the stop plate of the detection mechanism, the detection height is greater than the top surface height of the core when the core is not lifted by the detection rod, to prevent detection errors, and the detection range is set to a mesh shape, which can fully cover the entire detection groove area, when all the oil holes are penetrated, each infrared sensing device is not blocked and can detect the infrared signal, when the oil hole is blocked, the core in the corresponding area is lifted and blocks the infrared signal in the corresponding area, for example, if there is a blocked oil hole at the upper right corner of the core, the upper right corner of the core is lifted, and the signal emitting / receiving device at the upper right corner of the opposite infrared detection device is blocked, at this time only the lower left corner infrared detection device detects the signal, on the contrary, if there is a blocked oil hole on the left side of the core, the right side infrared detection device detects the signal, the application detects the approximate area of the blocked oil hole according to the signal state of the specific infrared detection device and the pre-set spatial coordinates, thereby greatly reducing the range of subsequent manual or equipment review.

[0025] 4、And, the application is combined by infrared detection and pressure detection, and the combination is analyzed based on intelligent control. Through the above control scheme, not only all oil holes of the iron core can be detected at one time, but also the depth of the blockage can be positioned through the detection value of the pressure sensor after the blockage is detected. The overall judgment process has high automation degree. Specifically, the application is provided with a quality detector. The feeding state of the iron core is judged through the change of the value detected by the quality detector. After the feeding is completed, the lifting mechanism is automatically transferred from the feeding station to the detection station through the transmission belt. The detection step is realized through the jacking of the lifting assembly, which greatly improves the detection efficiency, reduces the cost of manual operation and the error rate of manual operation.

[0041] The mounting bracket 1 has a feeding station and a detection station, and a transmission belt 5 is arranged between the mounting bracket 1 and the lifting mechanism 2, and the transmission belt 5 is configured to drive the lifting mechanism 2 to move on the mounting bracket 1.

[0042] The mounting groove 25 is further provided with a quality detector 6, and the top of the detection rod 22 is provided with a pressure sensor 7.

[0043] The application also provides a control method of the core oil hole penetration detection device, which comprises the following steps: S1, the lifting mechanism moves to the feeding station and remains stationary, while the quality detector detects the quality in the mounting groove; if the quality detector detects that the quality rises, it is judged that the current core feeding is completed, and the step S2 is continued to detect, otherwise, it is judged that the core is not fed;

[0044] S2, the transmission belt drives the feeding completed lifting mechanism to move to the detection station, the lifting assembly of the detection station pushes the lifting plate to move upward, the lifting plate lifts the bottom plate at the lifting mechanism, and the bottom plate and the mounting plate move to the baffle close to the detection mechanism;

[0045] S3, when the mounting plate moves to the detection groove of the detection mechanism, the core passes through the detection groove, and the mounting plate and the baffle interfere with each other, the lifting assembly continues to push, and under the action of the buffer spring, the mounting plate moves to the direction close to the bottom plate, and the detection rod passes through the through hole on the mounting groove and enters the oil hole of the core;

[0046] S4, the infrared detection device detects whether there is an infrared signal, if yes, it is judged that the oil hole of the current core is penetrated, and the core is qualified, otherwise, it is judged that the oil hole of the current core is blocked, the detection rod lifts the core and blocks the infrared line, the device stops working and notifies the staff to maintain.

[0047] Preferably, the step S4 further comprises a blocked oil hole detection method based on the infrared detection device, which comprises the following steps: S411, the infrared detection device detects the signal state, if the unilateral infrared detection device cannot detect the signal, it is judged that the unpenetrated oil hole is located close to the transverse or longitudinal column of the infrared detection device, and the subsequent staff is notified to detect the oil hole on this side;

[0048] S412, if the infrared detection device at the corner cannot detect the signal, it is judged that the unpenetrated oil hole is located close to the corner of the infrared detection device, and the subsequent staff is notified to detect the oil hole at the corner.

[0049] Preferably, the step S4 further comprises a clogged oil hole detection method based on the pressure sensor, comprising the following steps: S421, after the lifting assembly pushes the lifting mechanism, the pressure sensor at the top of each detection rod detects the pressure received thereby, if the pressure received by the pressure sensor at the top of each detection rod is 0, it is judged that the current iron core oil hole is through, and the iron core is qualified, otherwise, it is judged that there is a clogged oil hole, and jumping to S422 for position detection of the clogged oil hole;

[0050] S422, when there is a clogged oil hole, the detection rod detects the pressure received thereby, the detection value is P1, P2, P3……Px, and the detection rod receiving a pressure value > 0 is marked and recorded as an unpenetrated oil hole.

[0051] The present application forms an automatic high-precision oil hole penetration detection process through mechanical structure driving, sensor detection and algorithm judgment. Specifically, through the elastic buffer design of the lifting mechanism 2, when the iron core is not under pressure, the detection rod 22 is in a contracted state in the mounting groove 25 and will not be exposed outside the through hole 26. The lifting assembly 4 continuously jacks up the lifting mechanism 2, so that the lifting mechanism 2 reaches the detection mechanism 3. Since the size of the iron core is smaller than the size of the detection groove body 32, and the size of the detection groove body 32 is smaller than the size of the mounting plate 23, the iron core can pass through the detection groove body 32. When the iron core is normally placed on the mounting plate 23, the infrared detection device 33 is not blocked, and the lifting assembly 4 continues to move. At this time, the mounting plate 23 is attached to the bottom plate 21 under the action of the baffle 31 of the detection mechanism 3, the detection rod 22 on the bottom plate 21 passes through the through hole 26 and enters the oil hole of the iron core. If the iron core oil hole is clogged, the detection rod 22 lifts the iron core and blocks the signal of the infrared detection device 33, completing the automatic detection of the iron core. After the detection is completed, the lifting assembly 4 retreats to complete the reset. The overall process is simple, avoids the short-term shutdown caused by the manual reset of the dial piece type, and detects the oil hole in real time through infrared induction. No complex image processing is required. The detection method of the present application can accurately detect the position of the clogged oil hole and the depth position of the clogging in the iron core based on the spatial layout of the infrared detection device 33 and the detection value of the pressure sensor 7, providing extremely critical position information for subsequent maintenance or quality analysis, greatly improving the depth and value of the detection.

[0052] Further, the application suspends the mounting plate 23 above the bottom plate 21 and sets the buffer spring 27 between the mounting plate 23 and the bottom plate 21, when the mounting plate 23 is not under pressure or only under the gravity of the core, the detection rod 22 is in the through hole 26 of the mounting plate 23, when the mounting plate 23 is resisted by the baffle 31 and adheres to the bottom plate 21, the detection rod 22 can penetrate the oil hole of the core, and the oil hole penetration detection is completed, specifically, when the lifting assembly 4 pushes the bottom plate 21 upward, the mounting plate 23 first resists the baffle 31 of the detection mechanism 3, and the core penetrates the detection groove 32 of the detection mechanism 3, the lifting assembly 4 continues to push the bottom plate 21 to compress the buffer spring 27, so that the detection rod 22 can smoothly and controllably penetrate the through hole 26 of the mounting plate 23 and insert into the oil hole of the core, the buffer spring 27 can provide a relatively smooth insertion force for the detection rod 22, preventing the detection rod 22 from being damaged by impact at the blockage of the oil hole, if the detection rod 22 smoothly penetrates the oil hole, the core is normal, if there is a blockage, the blockage point will give pressure to the detection rod 22 and make the core lift, at this time the core will block the signal of the infrared detection device 33, so as to judge that the oil hole is not penetrated, and if the pressure sensor 7 on the top of the detection rod 22 is used to detect the blockage state of the oil hole of the core, when the detection rod 22 smoothly inserts into the oil hole, the sensor pressure is zero; if there is a blockage, the blockage point will exert pressure on the detection rod 22 and be accurately sensed and recorded by the sensor, so that the blocked hole can be easily found, and since the core is formed by stacking a plurality of steel sheets with the same thickness, the pressure received by the detection rod 22 can be based on the number of steel sheets, and since the mass of each steel sheet is the same, the number of lifted steel sheets can be determined based on the size of the pressure received, so as to obtain the depth position of the blockage.

[0053] Meanwhile, the application sets a plurality of infrared detection devices 33 on both sides of the baffle 31, the detection range of the infrared detection device 33 is set to the top of the baffle 31 of the detection mechanism 3, the detection height > the top surface height of the core when it is not lifted by the detection rod 22, preventing detection errors, and the detection range is set to a mesh shape, which can fully cover the entire detection groove 32 area, when all oil holes are penetrated, each infrared sensing device is not blocked and can detect the infrared signal, when the oil hole is blocked, the core in the corresponding area of the oil hole is lifted and blocks the infrared signal in the corresponding area, for example, there is a blocked oil hole at the upper right corner of the core, the upper right corner of the core is lifted, and the signal emitting / receiving device at the upper right corner of the opposite infrared detection device 33 is blocked, at this time only the lower left infrared detection device 33 detects the signal, on the contrary, if there is a blocked oil hole on the left side of the core, the right side infrared detection device 33 detects the signal, according to the signal state of the specific infrared detection device 33 and the pre-set spatial coordinates, the application can detect the approximate area of the blocked oil hole according to the signal blocking state, greatly reducing the range of subsequent manual or equipment review.

[0054] And, the application is combined by infrared detection and pressure detection, and is based on intelligent control for collaborative analysis, through the above control scheme, not only can the through detection of all oil holes of the iron core be carried out at one time, and the depth of the blockage can be positioned through the detection value of the pressure sensor 7 after the blockage is detected, and the degree of automation of the overall judgment process is high, specifically, the quality detector 6 is provided, the feeding state of the iron core is judged through the value change detected by the quality detector 6, after the feeding is completed, the automatic circulation of the lifting mechanism 2 from the feeding station to the detection station is realized through the transmission belt 5, the lifting of the lifting mechanism 2 is realized through the lifting assembly 4, the detection efficiency is greatly improved, the cost and the error rate of manual operation are reduced.

[0055] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, and the skilled in the art should include the changes and replacements within the technical scheme range of the present application in the protection range of the present application.

The lifting assembly at the inspection station pushes the lifting plate upward, and the lifting plate lifts the bottom plate at the lifting mechanism. The bottom plate and the mounting plate move toward the baffle close to the inspection mechanism. S3. When the mounting plate moves to the detection slot of the detection mechanism, the iron core passes through the detection slot. At the same time, the mounting plate and the baffle contact each other. The lifting assembly continues to push. At the same time, the mounting plate moves toward the bottom plate under the action of the buffer spring. The detection rod passes through the through hole on the mounting slot and enters the oil hole of the iron core. S4. The infrared detection device detects whether there is an infrared signal. If so, it is determined that the oil hole of the current iron core is through and the iron core is qualified. Otherwise, it is determined that the oil hole of the current iron core is blocked, the detection rod lifts the iron core and blocks the infrared rays, the device stops working and notifies the staff for maintenance.

9. The control method of the iron core oil hole penetration detection device according to claim 8, characterized in that: The step S4 also includes a method for detecting blocked oil holes using an infrared detection device, comprising the following steps: S411, the infrared detection device detects a signal status; if the infrared detection device on one side cannot detect a signal, it is determined that the blocked oil hole is located in a horizontal or vertical column close to the infrared detection device, and subsequent personnel are notified to inspect the oil holes on that side; S412: If the infrared detection device at the corner cannot detect a signal, it is determined that the unpenetrated oil hole is located at the corner close to the infrared detection device, and subsequent staff are notified to detect the oil hole at that location.

10. The control method of the iron core oil hole penetration detection device according to claim 8, characterized in that: The step S4 also includes a method for detecting a blocked oil hole based on a pressure sensor, comprising the following steps: S421, after the lifting assembly pushes the lifting mechanism, the pressure sensor on the top of the detection rod detects the pressure on it. If the pressure on the pressure sensors on the top of each detection rod is 0, it is determined that the oil hole of the current iron core is through and the iron core is qualified. Otherwise, it is determined that there is a blocked oil hole, and the process jumps to S422 to detect the position of the blocked oil hole; S422. When there is a clogged oil hole, the detection rod detects the pressure it receives, and the detection values ​​are P1, P2, P3...Px. The detection rod with a pressure value greater than 0 is marked and recorded as not penetrating the oil hole.
