Description

Technical Field

[0001] This invention relates to the field of stator production line technology, and in particular to a stator pressure welding measurement production line. Background Technology

[0002] The stator is a crucial component of motors such as generators and starters. The stator is the stationary part of the motor, and its main function is to generate a rotating magnetic field. The rotor's main function is to be cut by magnetic lines of force within this rotating magnetic field, thereby generating an electric current. Most existing stator cores are constructed by stacking and welding multiple identical stator laminations together using tooling.

[0003] Traditional stator pressure welding technology mostly relies on manual welding. After the stator is press-fitted, welding is performed. This welding process is largely done manually by production personnel who remove the press-fitted stator from the press-fitting machine and weld its outer surface. This method suffers from high labor intensity, low production efficiency, and inconsistent weld quality. Subsequently, stator pressure welding equipment has emerged. However, existing stator pressure welding equipment has the following shortcomings: 1. Existing stator pressure welding equipment typically uses a single cylinder for pressing. Limited by the air supply, the pressing force and position are prone to deviation, resulting in inconsistent extrusion quality across multiple stator products. 2. Existing stator pressure welding equipment only has a single station, and this single station is solely for pressure welding. After each pressure welding operation, the stator must be removed from the welding station before the next workpiece is placed in, impacting processing efficiency.

[0004] Furthermore, most existing stator measuring equipment is limited to measuring the dimensions and temperature of the stator. After measuring the stator, the equipment records the measurement information, then removes the measured stator from the equipment and transports stators of different categories to different storage locations to complete the stator quality classification. Therefore, most existing stator measuring equipment lacks the function of subsequent stator classification. Consequently, the entire process of measuring and classifying stators is labor-intensive and inefficient. Additionally, the handling process is prone to errors, leading to incorrect classification.

[0005] Current stator processing equipment generally consists of multiple single-function devices performing single-process operations. Then, through manual handling, the stator is processed multiple times by multiple devices to obtain the finished stator. Its level of automation is not high, which affects the overall processing efficiency and makes it difficult to meet the demand for higher processing efficiency and shorter delivery cycles.

[0006] Therefore, a new technical solution needs to be researched to address the above problems. Summary of the Invention

[0007] In view of this, the present invention addresses the deficiencies of the existing technology and its main objective is to provide a stator pressure welding measurement production line.

[0083] Preferably, the second conveying mechanism 300 is further provided with a limiting frame 302, which is arranged along the width direction of the second conveying mechanism 300 to adjust the height of the stator and prevent the stator from being stacked on the second conveying mechanism 300; and the top of the aforementioned partition plate 301 is connected to the lower end of the limiting frame 302 to fix the partition plate 301.

[0084] Next, in this embodiment, the general operation process of the present invention will be described as follows:

[0085] In the stator pressure welding equipment, the stator is installed on the loading station A, and the turntable 20 rotates the stator to the welding station B under the drive of the rotary motor 30; the first lifting mechanism 50 drives the pressure block 11 of the pressure device 10 to perform a downward pressing operation, squeezing the stator to complete the stator pressure welding process; under the drive of the second lifting mechanism 60, the laser welding device 40 performs laser welding processing on the periphery of the stator to complete the laser welding processing of the stator; and the height measuring device 70 measures the height of the stator.

[0086] The stator, after pressure welding, is moved to the stator measuring equipment by a transfer robot. Specifically, it is transported to the feed end of the first conveying mechanism 100. Under the transmission of the first conveying mechanism 100, the stator enters the measuring station, where the outer diameter is measured at the first measuring station E, and the height, tilt angle, temperature, and inner diameter are measured at the second measuring station F. The stator is moved out from the discharge end of the first conveying mechanism 100. Under the action of the slow-flow protrusion 207, the stator decelerates and enters the feed end of the diversion mechanism 200. The sliding block 203 moves left and right under the drive of the moving device 201, thereby controlling the stator to be divided into different zones. The stator passes through the roller shaft 208, enters the diversion conveying zone H through the feed end of the second conveying mechanism 300, and is sent out from the diversion conveying zone H.

[0087] The key design feature of this invention is that it achieves turntable-type loading, extrusion, laser welding, measurement, and defective product sorting of stators through the arrangement of a pressure welding worktable, turntable, pressure device, laser welding device, first conveying mechanism, diversion mechanism, and second conveying mechanism. It has a high degree of automation and effectively improves work efficiency.

[0088] Secondly, by improving the structure of the pressure device, double cylinders and double guide rods are used to drive the front and rear ends of the horizontal connecting rod. The pressure block is connected to the bottom center of the horizontal connecting rod. At the same time, movable holes are provided at the front and rear ends of the horizontal connecting rod to allow it to move up and down along the column. This effectively improves the stability of the downward pressing action and solves the problem that the downward pressure and position are prone to deviation in traditional technology, resulting in less than ideal consistency in the extrusion processing quality of multiple stator products.

[0089] Secondly, by improving the structure of the diversion mechanism, a sliding block is connected to the moving device. The front end of the sliding block is set with a V-shaped structure. At the same time, a partition plate is also set on the second conveying mechanism. The partition plate divides the second conveying mechanism into left and right diversion conveying areas to classify and convey different types of stators at the discharge end of the diversion mechanism, so as to facilitate the diversion processing of stators after measurement at the measuring station in the first conveying mechanism.
