Description

Technical Field

[0001] The utility model relates to the technical field of flat wire welding, in particular to TIG automatic welding equipment for motor flat wires. Background Art

[0002] As we all know, the motors used in new energy vehicles on the market are mainly permanent magnet synchronous motors and asynchronous motors with round wires. The slot fill rate of round wire motors is only about 40%, which means that the power density of the motor is low, the weight is heavy, and the power of electric vehicles is weak. Flat wire technology has been popularized in this context. With a higher slot fill rate and a lighter body, it not only improves the power of new energy vehicles, reduces power consumption, and reduces noise, but also allows manufacturers of new energy vehicles to reduce costs in automobile production parts. In the production process of flat wire motors, the flat wires are made of scattered wires, which are connected together through a welding process to achieve the purpose of coil closed loop. Flat wire welding will directly affect the quality of the motor. The patent proposed this time solves these problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The present invention will be described below based on the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. However, it is worth noting that the present invention is not limited to these embodiments. In the detailed description of the present invention below, some specific details are described in detail. However, for the parts that are not described in detail, those skilled in the art can also fully understand the present invention.

[0020] In addition, those skilled in the art should understand that the drawings are only provided to illustrate the purpose, features and advantages of the present invention, and the drawings are not actually drawn according to scale.

[0021] At the same time, unless the context clearly requires otherwise, the words "include", "comprises" and similar words throughout the specification and claims should be interpreted as inclusive rather than exclusive or exhaustive; that is, the meaning is "including but not limited to".

[0022] See also Figure 1-Figure 7 The utility model provides a technical solution: comprising a workbench 1, a rotating mechanism 2 is provided above the workbench 1, a fill light mechanism 8 is provided beside the rotating mechanism 2, the fill light mechanism 8 comprises a moving plate 801, an adjusting frame 802 and a fill light 803, a mechanical arm 4 is provided behind the rotating mechanism 2, a welding gun 6 and an industrial camera 7 are provided at the head of the mechanical arm 4.

[0023] The rotating mechanism 2 includes a hollow rotating platform 201 . A rotating motor 202 is disposed below the hollow rotating platform 201 . A positioning jig 203 is fixedly connected above the hollow rotating platform 201 .

[0024] The bottom of the movable plate 801 is interconnected with the workbench 1 through a slide rail 804 and a slider. The adjustment frame 802 is arranged on the movable plate 801 . The fill light 803 is arranged on both sides of the adjustment frame 802 . The fill light 803 can be located at the front and rear of the rotating mechanism 2 .

[0025] A positioning block 805 is provided below the movable plate 801. The positioning block 805 is provided with two pieces. The positioning block 805 is fixed to the workbench 1. A blind hole is provided in the middle of the positioning block 805. The movable plate 801 is provided with a latch 806, and the latch 806 can be inserted into the blind hole.

[0026] The welding gun 6 and the industrial camera 7 are interconnected with the head of the robot arm 4 through a connecting frame 5, and the bottom of the robot arm 4 is interconnected with the workbench 1 through a fixing seat 3.

[0027] A dust suction pipe 9 is also provided at the rear of the rotating mechanism 2 .

[0028] When using the utility model, the worker places the motor workpiece to be welded on the positioning jig 203, and then uses the controller to make the rotating motor 202 drive the hollow rotating platform 201 to automatically operate. The industrial camera 7 identifies the welding position, feeds back the position information, and transmits it to the robot arm 4. The robot arm 4 brings the welding gun 6 to the specified position. The worker moves the fill light mechanism 8 to the front and rear of the positioning jig 203 by pushing and pulling the moving plate 801, and inserts the pin 806 into the blind hole, as shown in the attached figure. Figure 7As shown, welding starts, and the smoke generated during the welding process is sucked away through the dust suction pipe 9. The lower end of the dust suction pipe 9 is connected to the existing vacuum cleaner. After welding, the completion information is fed back, and the overall control is controlled by the existing PLc. When the external staff sees the prompt, it means that the welding is completed and the welded motor workpiece can be taken out.

[0029] First, the positioning of the product. After the copper wire is arranged, it deforms greatly and moves up and down in the iron core, which seriously affects the welding quality. For the copper wire that has been arranged, we make special tooling to limit the height of the welding plane and the position of the welding copper wire, which can achieve an error within 0.1mm.

[0030] Second, there is the problem of identifying the position. The cross-section of the copper wire is reflective and is made of the same metal as the iron core, which increases the difficulty of identification. By using visual recognition technology and the coordination of multiple parties through fill light, position identification can be completed and the error can be reduced to within 0.1mm, meeting the welding requirements.

[0031] Third, the problem of collaborative operation. To complete the automated welding process, coordination between important actions such as positioning, identification, and welding is essential. During this period, the control module cooperated, the program was independently developed, and after a large number of experiments, the manual positioning and loading, automatic identification, and automated production of welding equipment were finally completed.

[0032] Fourth, the issue of flexible compatibility. Flat wire motors have a variety of product models. In order to save costs, each of our automation equipment can be compatible with several products at the same time, with simple switching in space, tooling, and procedures.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
