Description

Technical Field

[0001] The utility model relates to the field of technology for detecting the filling rate of insulating varnish in a stator, in particular to a device for detecting the filling rate of insulating varnish in a stator. Background Art

[0002] The stator generally includes silicon steel sheets and stator windings. The wires of the stator windings are enameled wires with insulating properties. Once the wires are separated, they are prone to wear due to the vibration of the motor, which ultimately affects the insulation effect. Therefore, the stator windings need to be insulated again, and the stator windings are bonded into an insulating whole as much as possible through insulating paint, so as to prevent the wires of the stator windings from loosening. At present, the common method is to drip or dip paint on the motor stator with the windings installed during the motor production process.

[0003] On the production line, the paint filling amount is usually detected by weighing the product before dripping (or dipping) the paint, and then weighing the product after dripping (or dipping) the paint. By comparing and analyzing the two weighing quantities, the paint filling amount can be obtained to ensure that the filled paint amount is qualified.

[0004] For products with higher requirements, it is also necessary to spot check the insulation paint filling inside the stator product. The current spot check method is to cut the middle part of the stator product (usually between the two ends, not limited to the center in a strict sense) along a plane perpendicular to its axial direction. In this way, the internal windings and insulation paint of the stator are exposed on the cut end face. The cut end face is manually checked to intuitively understand the insulation paint filling situation inside the stator. In actual operation, this method is not very practical, and it is difficult to form standardized and easy-to-quantify test results.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0037] The base 10 includes a base body, a support leg arranged at the bottom of the base body, and a support platform arranged at the top of the base body.

[0038] The placing table 20 is arranged on the machine base 10; the placing table 20 includes a stator positioning seat 21, a turntable 22, a horizontal rotation adjustment mechanism 23, an X-axis translation adjustment mechanism 24, and a Y-axis translation adjustment mechanism 25; wherein:

[0040] The top of the stator positioning seat 21 is provided with a stator placement position, and the size of the stator placement position is adjustable to meet the placement and positioning requirements of stators of different sizes (such as outer diameters), and is applicable to a variety of stator products and has strong practicality. In this embodiment, the stator positioning seat 21 includes four support positioning components, which are defined as a front support positioning component 1, a rear support positioning component 2, a left support positioning component 3 and a right support positioning component 4. The front support positioning component 1, the rear support positioning component 2, the left support positioning component 3 and the right support positioning component 4 all include a support column 211. The top of the support column 211 has a support surface 212 and a stop protrusion 213 located on the support surface 212. The stator placement position is defined by the stop protrusion 213 of the front support positioning component 1, the rear support positioning component 2, the left support positioning component 3 and the right support positioning component 4 respectively; the front support positioning component 1 and the rear support positioning component 2 are both horizontally adjustable along the Y-axis, and the left support positioning component 3 and the right support positioning component 4 are both horizontally adjustable along the X-axis to change the size of the area defined by the stop protrusion 213, that is, to achieve adjustable size of the stator placement position. The lower end of the support column 211 is connected to a sliding seat 214, and a locking piece 217 is provided on the sliding seat 214; accordingly, the turntable 22 is provided with two first X-axial slide rails 215 arranged opposite to each other left and right, and two first Y-axial slide rails 216 arranged opposite to each other front and back; the sliding seats 214 of the left support positioning assembly 3 and the right support positioning assembly 4 can be slidably adapted to the corresponding first X-axial slide rails 215 left and right, and the sliding seats 214 of the front support positioning assembly 1 and the rear support positioning assembly 2 can be slidably adapted to the corresponding first Y-axial slide rails 216 front and back; the locking piece 217 is used to lock the position of the sliding seat 214 after sliding adjustment. The locking member 217 includes a locking bolt, which passes through a through hole on the sliding seat 214. When in a locked state, the inner end of the screw of the locking bolt abuts against the corresponding first X-axis slide rail 215 or the first Y-axis slide rail 216, and the cap of the locking bolt presses against the outer surface of the sliding seat 214; or, the locking member 217 includes a locking screw and a locking nut, which passes through a through hole on the sliding seat 214.

The side of the turntable 22 corresponding to the first X-axis slide rail 215 and the first Y-axis slide rail 216 is provided with a scale mark, which is convenient for visual inspection and proofreading during adjustment. Therefore, when adjusting the stator placement position according to different stator product sizes, the operation is convenient, and the adjustment state change can be intuitively displayed.

[0041] The horizontal rotation adjustment mechanism 23 includes a knob 231 and a gear. The gear and the knob 231 are coaxially connected. The knob 231 is exposed at the top of the base 10. The bottom of the turntable 22 is provided with a toothed portion, and the gear is engaged with the toothed portion. When the knob is turned, the knob drives the gear to rotate horizontally around the Z-axis direction, and the gear drives the toothed portion to drive the turntable 22 to rotate horizontally. The X-axis translation adjustment mechanism 24 is connected to the Y-axis translation adjustment mechanism 25 to drive the Y-axis translation adjustment mechanism 25 to translate along the X-axis together with the turntable 22. The Y-axis translation adjustment mechanism 25 directly drives the turntable 22 to translate along the Y-axis. The X-axis translation adjustment mechanism 24 includes an X-axis sliding tray, a base plate is arranged below the X-axis sliding tray, a second X-axis slide rail is arranged on the base plate, and the X-axis sliding tray is slidably arranged along the second X-axis slide rail; and a second Y-axis slide rail is arranged on the X-axis sliding tray; the Y-axis translation adjustment mechanism 25 includes a Y-axis sliding tray, the Y-axis sliding tray is located on the X-axis sliding tray, and is slidably arranged along the second Y-axis slide rail; the turntable 22 is arranged on the Y-axis sliding tray, and can rotate horizontally relative to the Y-axis sliding tray.

[0042] In this embodiment, the horizontal rotation adjustment mechanism 23, the X-axis translation adjustment mechanism 24, and the Y-axis translation adjustment mechanism 25 are all described by taking the manual adjustment structure as an example. In other embodiments, some or all of the adjustment mechanisms may also adopt an automatic structure, such as an electric structure. In comparison, the manual adjustment structure has a simple structure and low cost, while the automatic adjustment structure has a higher degree of intelligence. An operation panel can be set on the machine base 10 to set relevant parameters to control it to automatically adjust to a stator placement position of a suitable size, and to control it to rotate the stator product at a set speed, horizontally translate the stator product in the X and Y axes, that is, translate and rotate the stator product during the inspection process, so that the stator product is below the visual inspection module 40, and the entire cut end face is gradually picked up by the image.

[0043] The lifting module 30 is placed on the machine base 10 and is located at the rear side of the placement table 20; the lifting module 30 includes a stand 31 and a Z-axis lifting drive mechanism 32 arranged on the stand 31. The Z-axis lifting drive mechanism 32 can adopt a manual adjustment mechanism or an electric adjustment mechanism. The manual adjustment mechanism includes a rotating handle 321, a sprocket, and a chain. When the rotating handle is rotated, the sprocket rotates, and the chain moves with the rotation of the sprocket. A lifting mounting seat 322 is connected to the chain, and the lifting mounting seat 322 is lifted and lowered along the Z-axis with the movement of the chain. For the electric adjustment mechanism, the manual power of the rotating handle can be changed to a motor. In this article, only one feasible solution of a manual adjustment mechanism and an electric adjustment mechanism is listed. In specific implementation, the manual and electric adjustment mechanisms are not limited to this structure. How to realize the Z-axis lifting drive is a very common technical means for technicians in the mechanical equipment industry, and it will not be repeated here.

[0044] The visual inspection module 40 is arranged on the stand 31, and is driven by the Z-axis lifting drive mechanism 32 to be adjustable in the Z-axis direction relative to the stand 31. The visual inspection module 40 includes a CCD unit, a UV lamp, and a positioning laser lamp. The CCD unit is used to photograph the stator cut end face, and the UV lamp emits UV light toward the stator cut end face to facilitate displaying the image of the stator cut end face, clearly showing the outline of the position of the insulating paint and the position of the empty slot that is not filled with insulating paint, and the positioning laser lamp emits laser for positioning.

[0045] The display 50 is disposed on one side (eg, the left side or the right side) of the stand 31 , and is electrically connected to the visual inspection module 40 for displaying the image of the stator cutting end surface photographed by the visual inspection module 40 .

[0046] During measurement, first adjust the stator positioning seat 21 of the placement table 20 so that the stator placement position matches the stator product to be measured, then place the stator product (with the cut end facing upward) on the stator placement position, and adjust the horizontal position of the turntable 22 through the X-axis translation adjustment mechanism 24 and the Y-axis translation adjustment mechanism 25 so that the part of the annular edge of the stator product is directly opposite to the bottom of the visual inspection module 40. The Z-axis height adjustment of the visual inspection module 40 can be based on the principle that it can capture the partial full picture of the annular edge of the stator product. Then, use the horizontal rotation adjustment mechanism 23 to control the turntable 22 to rotate slowly horizontally. In this way, the picture of the entire cut end face of the stator product can be gradually obtained along the annular extension direction. On the basis of obtaining multiple images of the local cut end face, it is convenient for technical personnel to further form standardized and easily quantifiable detection results. The base 10 can also be connected to a computer, and its image data is transmitted to the computer. Since the position of the insulating paint and the position of the empty slot that is not filled with insulating paint can be clearly displayed on the image, the area of ​​the empty slot position that is not filled with insulating paint can be calculated by analyzing the image of the stator cut end face, and the filling rate can be calculated.

[0047] The design focus of the utility model is that it mainly develops a stator internal insulating paint filling rate detection device, including a base 10, a placement table 20, a lifting module 30, a visual inspection module 40 and a display 50. The placement table 20 is used to place and position the stator product to be detected, and the stator product can be translated and rotated horizontally along the X / Y axis on the placement table 20 as needed. The lifting module 30 can drive the visual inspection module 40 to be lifted and lowered along the Z axis to meet the visual inspection module for visual inspection of the cut end face of the stator product. At the same time, the display 50 displays the image of the stator cut end face taken by the visual inspection module 40, which is conducive to the technical personnel to further form standardized and easy-to-quantify detection results, and effectively solves the problem that the stator internal insulating paint filling rate detection method in the traditional technology is not practical and difficult to form standardized and easy-to-quantify detection results.

[0048] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
