Description

Technical Field

[0001] The utility model relates to the technical field of laser welding equipment, in particular to a motor core laser welding CCD detection component. Background Art

[0002] The motor core is the rotating part of the electric motor, including the core, rotor winding and shaft. The rotor winding can cut the stator magnetic field, generate induced electromotive force and current, and under the action of the rotating magnetic field, the rotor is forced to rotate.

[0003] In the processing of motor core parts, it is necessary to weld the motor core. Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. Laser welding can reduce the required amount of heat input to the minimum, the metallographic change range of the heat-affected zone is small, and the deformation caused by heat conduction is also minimal; it is particularly suitable for the welding of motor cores, and the welding speed is fast while keeping the core deformation small.

[0004] However, when laser welding the motor core, it is necessary to locate and verify the position of the core to be fed, so as to make the automatic welding more accurate. In the existing technology, the size of the product is detected manually, which is troublesome, time-consuming and labor-intensive, and is not conducive to the detection of batch products; at the same time, there is a certain error in the manual detection of product size. The CCD image detection device can directly convert the optical signal into a digital electrical signal to achieve image acquisition, storage, transmission, processing and reproduction. Its notable features are: 1. Small size and light weight; 2. High sensitivity, low noise, and large dynamic range; 3. Fast response speed, self-scanning function, small image distortion, and no afterimage; 4. It is produced using ultra-large-scale integrated circuit process technology, with high pixel integration, precise size, and low commercial production cost.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] A motor core laser welding CCD detection component, such as Figure 1As shown, it includes a dividing plate 1, which is arranged on a processing platform 7. A drive box 8 is arranged on the processing platform 7. The dividing plate 1 is rotatably arranged on the drive box 8. A reduction motor 9 is arranged on one side of the drive box 8. The reduction motor 9 drives the dividing plate 1 to rotate. A plurality of processing stations 2 are evenly distributed on the dividing plate 1. Specifically, each processing station 2 can be divided into a loading station, a standby station, a welding station, and an unloading station. When the dividing plate 1 rotates, the motor core 36 positioned by the core fixture on each processing station 2 is rotated, so as to realize the assembly line movement of the motor core 36 between each station; it can be understood that when the motor core 36 is loaded, it is necessary to measure whether the core loading position is accurate, or when the position of other stations needs to be calibrated, visual inspection can be performed through this CCD detection component.

[0022] Specifically, the indexing plate 1 is provided with a mounting frame 3 that rotates around the center of the indexing plate 1, and the mounting frame 3 is provided with a visual inspection device. The mounting frame 3 rotates around the center of the indexing plate 1 to move the visual inspection device between each processing station 2; Figure 1 , 2 As shown, when a workpiece is placed on the loading station, the motor core 36 is visually inspected by the CCD detection component. The mounting frame 3 is controlled so that the CCD detection component faces the loading station. The mounting frame 3 includes a rotating shaft 4, a rotating plate 5, and a column 6. The rotating shaft 4 is coaxially arranged with the indexing plate 1. One end of the rotating shaft 4 extends out of the upper end surface of the indexing plate 1 and is fixedly connected to one end of the rotating plate 5. The upper end surface of the other end of the rotating plate 5 is vertically provided with a column 6, and the visual inspection device is arranged on the column 6.

[0023] In this embodiment, the visual inspection equipment includes an upper camera 18 and a lower camera 19; both the upper camera 18 and the lower camera 19 are CCD industrial cameras, and the corresponding motor core 36 to be inspected is provided with a calibration position for inspection. Specifically, a lower outer diameter groove 22 is provided on the lower part of the outer wall of the motor core 36, and an upper inner hole groove 23 is provided inside.

[0024] Specifically, a through hole 10 for the rotary pull to pass through is provided at the center of the dividing plate 1; thereby, the mounting frame 3 and the dividing plate 1 can rotate independently of each other.

[0025] As an embodiment, the rotation of the mounting frame 3 is manually adjusted and positioned. In actual use, the CCD detection component can be fixed toward a certain workstation and fixed in position. It can be understood that when the position needs to be changed, the positioning of the rotating shaft 4 can be loosened, and the mounting frame 3 can be rotated toward other workstations and fixed in position. In this way, a set of CCD detection components can be used for multiple workstations.

[0026] As another embodiment; a servo motor is provided inside the drive box 8, and the output end of the servo motor is connected to the rotating shaft 4. In actual use, the servo motor controls the mounting frame 3 to rotate at a fixed angle relative to the dividing plate 1, so that the visual inspection equipment can be used for each processing station 2. When in use, the servo motor can move the CCD inspection component toward the required station for visual inspection at any time as needed.

[0028] The column 6 is provided with an upper camera 18, a lower camera 19, a fill light platform 20, and a strip light source 21. The upper camera 18 and the lower camera 19 are both mounted on the column 6 through an adjustable frame. The fill light platform 20 is provided with a strip light source 21; the strip light source 21 provides fill light from both sides of the outer diameter groove 22 at the lower end.

[0029] like Figure 3As shown, the adjustable frame includes a clamping portion 25, a mounting plate 26, and an adjustable angle code 27. The clamping portion 25 includes a rectangular clamping body, the clamping body is provided with a clamping hole 28, a second opening 29 is provided on one side of the clamping body, and second locking screw holes 30 are provided on both sides of the second opening 29.

The center of the arc-shaped waist hole 33 coincides with the center of the center hole 32. The clamping portion 25 can be fixedly clamped on the column 6 by installing the bolt in the second locking screw hole 30, and the horizontal deflection angle of the CCD camera can be adjusted individually. An adjustable angle code 27 is arranged on the side of the mounting plate 26. In actual use, screws are arranged in the center hole 32 and the arc waist hole 33, and are screwed into the mounting hole 31. The center hole 32 can make the adjustable angle code 27 adjust the pitch angle in the longitudinal direction, that is, adjust the pitch angle of the CCD camera. When the arc waist hole 33 is locked, the position of the adjustable angle code is fixed. In this way, the horizontal angle or vertical angle of the CCD camera can be adjusted individually.

[0030] The light-filling platform 20 includes a platform plate 35 and a clamping portion 25. Two longitudinally arranged strip light sources 21 are provided on the upper end surface of the platform plate 35 near the motor core 36. The strip light sources 21 are arranged on both sides of the lower camera 19. The side of the platform plate 35 near the column 6 is fixed to the column 6 by the clamping portion 25. The light-filling platform 20 is also fixed by the aforementioned clamping portion 25, and the strip light sources 21 are used to fill light for the detection of the CCD camera.
