[0001] This utility model relates to the technical field of iron core processing equipment, and in particular to a burr detection device for the inner wall of an iron core for a new energy vehicle motor. Background Technology

[0002] After the initial processing and forming of the core of the motor for new energy vehicles, burrs may be present on the inner wall of the cavity due to processing precision and other reasons. The presence of burrs will not only affect the assembly process of the motor, but also have an adverse effect on the electrical and mechanical performance of the motor. Therefore, it is necessary to inspect the inner wall of the cavity of the motor core for burrs and other foreign objects.

[0003] The current mainstream method involves taking photos at a fixed position using a telecentric lens camera assembly. The image information received by the camera assembly is then compared and marked, which also facilitates burr removal in subsequent processes. However, since the object being inspected is the inner wall of the motor core cavity, which is parallel to the central axis of the camera, the inspection angle is limited, and it is difficult to guarantee the inspection effect.

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figures 1 to 3 As shown, a burr detection device for the inner wall of a new energy vehicle motor core includes a machine base 10, a lifting module 20, a detection module 30, a translation module 40, and a rotation module 50. The lifting module 20 is mounted on the machine base 10 via a support plate 200 and can be an electric cylinder. The detection module 30 is mounted on the lifting module 20. The detection module 30 includes a bracket 31, a camera assembly 32, a reflecting prism 33, and a light strip 34. The bracket 31 is located at the output end of the lifting module 20, the camera assembly 32 is located on the upper part of the bracket 31, and the reflecting prism 33 is located on the lower part of the bracket 31. The reflecting prism 33 is configured such that its reflecting surface is inclined. The angled arrangement refracts the light, which is then received by the camera assembly 32. The light strip 34 is mounted on the bracket 31 and located below the reflecting prism 33. The translation module 40 is mounted on the machine base 10 and can be a cylinder. The translation module 40 is equipped with a rotating module 50, which can be a rotating worktable. The rotating module 50 is equipped with a positioning fixture for positioning the motor core 100. The translation module 40 can drive the motor core 100 located on the positioning fixture to move to below the reflecting prism 33, and the reflecting prism 33 is driven to move down into the middle cavity of the motor core 100. The rotating module 50 drives the motor core 100 located on it to rotate.

[0022] In this invention, the motor core 100 is placed in a positioning fixture on the rotating module 50. The translation module 40 drives the rotating module 50 and the motor core 100 located on the rotating module 50 to move below the reflecting prism 33. After moving into position, the lifting module 20 drives the bracket 31 and the reflecting prism 33 and light strip 34 located on the bracket 31 to move downwards, so that the reflecting prism 33 and light strip 34 extend into the cavity of the motor core 100. The camera assembly 32 located on the bracket 31 moves downwards simultaneously, but remains above the motor core 100. When the reflecting prism 33 and light strip 34 extend into the cavity of the motor core 100, the light emitted by the light strip 34 can illuminate the inner wall of the cavity of the motor core 100. The image information (whether there are burrs) on the inner wall of the cavity of the motor core 100 is reflected by the reflecting prism 33 to the camera assembly 32, and the camera assembly 32 acquires the image. The image information can be input to the image processor to determine whether there are burrs; since the motor core 100 is located on the rotating module 50, the motor core 100 can be rotated by the rotating module 50. During the rotation of the motor core 100, the image information of the entire cavity wall can be reflected into the camera assembly 32 by the reflecting prism 33. In this action mode, the reflecting prism 33 and the light strip 34 can remain unchanged after moving down. It is suitable for motor cores 100 with a small height. Furthermore, in another embodiment, during the rotation of the motor core 100, the lifting module 20 can drive the reflecting prism 33 to move from top to bottom to cover the height range of the motor core 100. If the motor core 100 has a high height, the movement of the reflecting prism 33 and the light strip 34 can achieve complete coverage of the inner wall of the middle cavity of the motor core 100. It should be noted that the light strip 34 can be a flexible circuit board + LED light beads structure. Since the light strip 34 is located at the lower end of the bracket 31 and below the reflector prism 33, when the reflector prism 33 and the light strip 34 extend into the cavity of the motor core 100, in order to improve the lighting effect and coverage of the light strip 34 (i.e., to ensure that the light can cover the entire range of the height direction of the inner wall of the cavity of the motor core 100), the LED light beads are preferably diffused type light beads, which can have a wider light emission angle (such as 45°-90° or larger), and can realize wide-angle lighting.

[0023] The light strip 34 of this utility model is set on the bracket 31 and located below the prism 33. The light strip 34 occupies a certain space only in the vertical direction and does not occupy space in the horizontal direction. While providing illumination with the reflection prism 33 extending into the cavity of the motor core 100, it is not affected by the size of the cavity of the motor core 100. It can be better suited for detecting burrs on the inner wall of the cavity of motor cores with different cavity sizes.

[0024] Preferably, the reflecting prism 33 is an isosceles right-angle prism, and the support 31 includes a vertical plate 311 and a horizontal plate 312. The vertical plate 311 is set at the output end of the lifting module 20 through the connecting frame 201, and the horizontal plate 312 is set at the lower end of the vertical plate 311. One right-angle side of the reflecting prism 33 is set on the horizontal plate 312, which can ensure the stability of the support for the reflecting prism 33. The light strip 34 extends horizontally and is set at the end of the horizontal plate 312 away from the vertical plate 311, and it protrudes from the reflecting prism 33 in the horizontal direction, so that it is located below the reflecting prism 33 but does not affect its lighting effect. The camera assembly 32 is set on the upper part of the vertical plate 311.

[0025] Furthermore, the other right-angled side of the reflecting prism 33 abuts against the upright plate 311, which enables precise positioning of the reflecting prism 33.

[0026] In one embodiment, the lower end of the reflecting prism 33 is bonded to the horizontal plate 312 to ensure the stability of the reflecting prism 33 on the support 31.

[0027] like Figure 4 As shown, in another embodiment, the horizontal plate 312 includes a base plate 3121 and a side plate 3122. The light strip 34 is disposed on the side plate 3122. The side plate 3122 is locked to the end of the base plate 3121 away from the vertical plate 311 by a locking member 3123 and abuts against the reflecting prism 33. In this embodiment, the reflecting prism 33 is not glued to the horizontal plate 312, but is fixed to the horizontal plate 312 by having one right-angled side abutting against the base plate 3121, another right-angled side abutting against the vertical plate 311, and one side edge abutting against the side plate 3122. This method facilitates the disassembly, maintenance, and replacement of the reflecting prism 33. Moreover, since the light strip 34 is disposed on the side plate 3122, it is also convenient to remove the side plate 3122 from the base plate 3121 for maintenance or replacement.

[0028] Furthermore, a flexible pad (not shown) is provided at the upper end of the side plate 3122. The flexible pad is in interference fit with the reflective prism 33. The flexible pad can avoid damage to the reflective prism 33 caused by rigid contact and can improve the stability of fixing the reflective prism 33.

[0029] Preferably, the camera assembly 32 includes two cameras arranged side by side along the inclined extension direction of the reflecting surface of the reflecting prism 33, which can more efficiently realize the reception of image information of the inner wall of the central cavity of the motor core 100.

[0030] In addition, the machine base 10 is provided with a mounting plate 601, and the side wall of the mounting plate 601 is provided with a material feeding sensor 61; the machine base 10 is provided with a frame 101, and the frame 101 is provided with a safety light curtain 70.

[0031] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
