Description

Technical Field

[0001] The invention relates to the field of magnetic core production equipment, in particular to a magnetic core measuring device. Background Art

[0002] The magnetic core is mainly used in various power conversion equipment. It is one of the core components of the power conversion equipment. The performance of the magnetic core directly affects the efficiency of the power conversion equipment. The size of the magnetic core is one of the important parameters of the magnetic core. The specific size value of each magnetic core needs to be determined before the magnetic core leaves the factory. Among the multiple dimensions of the magnetic core, the bottom thickness and A dimension are the necessary measurement dimensions before leaving the factory. When measuring, the magnetic core is placed horizontally with the raised part facing vertically upward. Figure 1 a~ Figure 1 d shows the main view, top view, side view and overall structure diagram of a magnetic core, where the bottom thickness refers to the vertical height of the remaining part of the magnetic core after removing the protrusion. Figure 1 The value position of the bottom thickness is marked in a. The full name of the A dimension is the maximum dimension in the length direction of the core (hereinafter referred to as the A dimension). The measurement position is on the top surface of the core. Figure 1 The value position of dimension A is indicated in b.

[0003] The inventor knows that the bottom thickness of the magnetic core currently needs to be measured manually, and a caliper is used for manual contact measurement. Due to the limitation of processing accuracy, there must be an acceptable flatness error on the surface of the magnetic core, which makes the bottom thickness at different positions on the magnetic core different. Therefore, the original measurement data of the bottom thickness should be a vertical range, and the caliper can only measure the size of one position. Even if a multi-point measurement method is used, it is impossible to obtain comprehensive bottom thickness data, and the true bottom thickness cannot be obtained. The measurement is inaccurate and the efficiency is low. The general measurement method of A size is to use a grating ruler for mechanical measurement, which is easy to cause damage to the magnetic core. In addition, the current measurement of the bottom thickness and the measurement of the A size are carried out separately, and there is no mature bottom thickness and A size measurement equipment available for purchase and use.

Therefore, the features defined as "first", "second", etc. can explicitly or implicitly include one or more of the features.

[0037] It should also be noted that in the embodiments of the present application, the same figure mark is used to represent the same component or the same part.

[0038] The purpose of the present invention is to provide a magnetic core measuring device to solve the problems existing in the prior art, including completing a bottom thickness measuring system and an A-size measuring system, wherein the bottom thickness measuring component scans the magnetic core to generate a three-dimensional image, and the maximum bottom thickness and the minimum bottom thickness on the magnetic core are obtained by analyzing the three-dimensional image, and the A-size measuring component can obtain the top surface image of the magnetic core, and the maximum A-size and the minimum A-size of the magnetic core are obtained by analyzing the top surface image, thereby realizing contactless and comprehensive measurement of the bottom thickness and A-size of the magnetic core, obtaining accurate bottom thickness and A-size data without causing damage to the magnetic core.

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] like Figure 2As shown, the present invention provides a magnetic core measuring device, including a bottom thickness measuring system 8 and an A-size measuring system 10. The bottom thickness measuring system 8 includes a bottom thickness measuring component and a bottom thickness measuring platform 7. The bottom thickness measuring component is arranged above the bottom thickness measuring platform 7. After the magnetic core 21 is arranged on the bottom thickness measuring platform 7, the bottom thickness measuring component scans the magnetic core 21 to generate a three-dimensional image of the magnetic core 21, and analyzes the three-dimensional image to obtain the maximum bottom thickness and the minimum bottom thickness of the magnetic core 21. The A-size measuring system 10 includes an A-size measuring component and an A-size measuring platform. The A-size measuring component is arranged above the A-size measuring platform. After the magnetic core 21 is arranged on the A-size measuring platform, the A-size measuring system 10 obtains the top surface image of the magnetic core 21, and obtains the maximum A-size and the minimum A-size of the magnetic core 21 by analyzing the top surface image. The value position of the A-size of the bottom thickness of the magnetic core 21 has been marked. Figure 1 In the present invention, due to the allowable design tolerance and manufacturing errors caused by various reasons, the measured values ​​of the bottom thickness and the A size will be different due to different measuring positions. Therefore, the bottom thickness and the A size should be a numerical range with a maximum value and a minimum value. The present invention adopts a visual measurement method to perform non-contact measurement on the magnetic core 21. The bottom thickness extreme value and the A size extreme value of the measured magnetic core 21 are obtained by processing and analyzing the obtained three-dimensional morphology and two-dimensional images, thereby obtaining the numerical range of the bottom thickness and the A size. In the process of measuring the bottom thickness, the zero reference plane of the scan is the upper surface of the bottom thickness measurement platform 7, and the accurate parameters of the bottom thickness can be directly obtained. In the process of measuring the A size, the straight line where the A size is located is parallel to the long side of the magnetic core. For the magnetic core 21 with an arc-shaped short side edge, the A size refers to the maximum size obtained by measurement.

[0041] In one embodiment, the bottom thickness measurement system 8 has a zero reference plane measurement function. When the zero reference plane is uneven, collapsed or other abnormal conditions occur, the bottom thickness measurement system 8 will issue a prompt to remind the operator to perform a zero adjustment operation.

[0042] In one embodiment, the A-size measurement system 10 has an image deformation recognition function. When the A-size measurement platform is uneven, the magnetic core 21 placed thereon and its posture will change, resulting in inconsistency between the captured image and the image that meets the measurement standard. The image deformation recognition function can identify the wrong image, and the A-size measurement system 10 will issue a prompt to remind the operator to eliminate the problem.

[0043] like Figure 3As described above, in one embodiment, the bottom thickness measurement assembly includes a bottom thickness measurement camera 29, which includes a laser transmitter and a receiver for receiving reflected laser light. The laser transmitter transmits laser light to scan the magnetic core 21, and the receiver receives the trajectory of the reflected laser light to generate a three-dimensional image of the magnetic core 21. The three-dimensional image is analyzed to obtain the maximum bottom thickness and the minimum bottom thickness. When the laser light scans positions at different heights, the time at which the receiver receives the reflected laser light is also different. The position where the laser light passes can be calculated by comparing the height of the zero reference plane through the speed and movement time of the laser light to obtain the bottom thickness value.

[0044] In one embodiment, the bottom thickness measurement camera 29 may also be an electromagnetic wave profile scanning device, such as an infrared three-dimensional imager, a millimeter wave three-dimensional imager, and the like.

[0048] like Figure 4 and Figure 5 As shown, in one embodiment, the synchronous belt 19 driving assembly includes a servo motor 13, the servo motor 13 is fixedly connected to the bottom thickness measuring platform bracket 27 through the servo motor bracket 22, the output end of the servo motor 13 is connected to the driving wheel shaft 17 through the coupling 23, the driving wheel 24 for driving the synchronous belt 19 is arranged on the driving wheel shaft 17, the driven wheel 25 for assisting the rotation of the synchronous belt 19 is arranged on the driven wheel shaft 18, the driven wheel shaft 18 is arranged on the bottom thickness measuring platform bracket 27, and a synchronous belt support plate 26 for supporting the synchronous belt 19 is arranged between the driving wheel 24 and the driven wheel 25.

[0049] like Figure 5 As shown, in one embodiment, a block 20 for spacing the magnetic core 21 is provided on the synchronous belt 19. When there are not less than two blocks 20, the blocks 20 are evenly spaced. The blocks 20 can divide the synchronous belt 19 into multiple sections with equal spacing. One (or other number) of magnetic cores 21 can be placed in each section. When measuring, the measurement is performed according to the section, ensuring that only one (or a certain number) of magnetic cores 21 are measured each time, so that the measurement result is more accurate.

[0050] like Figure 4 As shown, in one embodiment, the bottom thickness measurement platform 7 further includes a plate 15 for temporarily placing the magnetic core 21 that has completed the bottom thickness measurement, and the plate 15 is arranged at the discharge end of the synchronous belt 19. When the magnetic core 21 that has completed the bottom thickness measurement is inconvenient to directly enter the next link but the bottom thickness measurement needs to be continued, the plate 15 provides an area for placing the magnetic core 21, and the synchronous belt 19 can continue to work to replace the magnetic core 21 to be measured, and the magnetic core 21 that is separated from the synchronous belt 19 will not enter the next link, thereby ensuring the continuity of the bottom thickness measurement.

[0054] like Figure 4As shown, in one embodiment, the synchronous belt 19 is provided with relative stoppers 14 and 16 on both sides close to the piece-passing plate 15. The function of the stoppers 14 and 16 is to ensure that the magnetic core 21 is not skewed, so that the magnetic core 21 dropped on the piece-passing plate 15 can maintain a posture that is convenient for the push cylinder 9 to push out. The stoppers 14 and 16 also have a posture adjustment function. For a skewed magnetic core 21, the stoppers 14 and 16 can adjust the magnetic core 21 to a posture that is convenient for the push cylinder 9 to push out.

[0055] like Figure 2 As shown, in one embodiment, the feed end of the discharge conveyor belt 11 is provided with an A-size measuring system trigger mechanism 12 for measuring the upper part of the magnetic core 21. When the A-size measuring system trigger mechanism 12 measures the measured magnetic core 21, the A-size measuring system 10 is started to measure the magnetic core 21 and send out the measured magnetic core 21.
