Description

A paint removal vacuuming mechanism and method Technical Field

[0001] This invention relates to the field of flat wire motor assembly equipment technology, and in particular to a paint removal and dust extraction mechanism. Background Technology

[0002] Flat wire motors typically consist of a stator, rotor, and reducer, with the stator being one of the core components. The stator is the stationary part of the motor, usually composed of coils wound with copper wire, and is fixed in place within the motor housing. Its main function is to generate a magnetic field, driving the rotor to rotate and thus completing the motor's operation.

[0003] The primary function of the stator in a flat-wire motor is to generate a magnetic field, which can be a constant direct current (DC) magnetic field or a changing alternating current (AC) magnetic field. When the current through the stator coils changes, a change in magnetic flux is generated in the conductor. This change in magnetic flux affects the shape of the magnetic field, which in turn determines the direction and speed of the rotor's rotation. The magnetic field generated in the stator interacts with the magnetic field present in the rotor, causing the rotor to rotate under the influence of torque.

[0004] With continuous innovation and advancements in flat wire stators, and the application of X-Pin and ultra-short-cut stators, the requirements for stator production are becoming increasingly stringent, demanding higher cycle times. During the copper wire stripping process, single or double suction ports are typically used. However, this inevitably leads to incomplete stripping of the copper wire surface, resulting in black spots and other defects. This negatively impacts the subsequent welding pass rate and overall quality. Therefore, a highly efficient and rapid dust extraction mechanism is urgently needed. Summary of the Invention

[0010] Furthermore, a gas flow sensor is installed at the hose interface.

[0011] The second aspect of this invention discloses a four-suction paint removal and dust collection method, which employs a paint removal and dust collection mechanism disclosed in the first aspect of this invention.

[0012] Furthermore, the effect of laser paint removal is observed manually or by testing equipment, while the gas flow sensor monitors the gas flow at the suction port in real time. When it is determined that the dust removal effect is poor due to insufficient gas flow, the laser paint removal dust removal is suspended, at least one suction hose is removed, and an air blowing hose connected to the air supply equipment is installed.

Obviously, the described examples are only a part of the examples of the present invention, and not all of them. Based on the examples in the present invention, all other examples obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used in the detailed description is for the purpose of describing particular examples only and is not intended to limit the invention; the terms “comprising” and “having”, and any variations thereof, in the specification, claims and foregoing description of the invention are intended to cover non-exclusive inclusion.

[0020] In the description of specific embodiments of the present invention, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of examples of the present invention, "multiple" means two or more, unless otherwise explicitly defined.

[0021] In this invention, the term "example" means that a particular feature, structure, or characteristic described in connection with an example can be included in at least one example of the invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same example, nor is it a mutually exclusive, independent, or alternative example. It will be explicitly and implicitly understood by those skilled in the art that the examples described in this invention can be combined with other examples.

[0022] In the description of the embodiments of this invention, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Furthermore, in this invention, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0023] The embodiments of the present invention will be described in more detail below through examples. It should be noted that the embodiments of the present invention are not limited to these examples.

[0024] In a specific example, as shown in Figures 1-5, the first aspect of the present invention discloses a paint removal and dust extraction mechanism, including a housing assembly 1, a dust extraction assembly 2, and a copper wire guide assembly 3; the dust extraction assembly 2 is provided with a first hose interface 21, a second hose interface 24, a third hose interface 26, and a fourth hose interface 29.

[0025] The copper wire guide assembly 3 is fixedly connected to the dust collection assembly 2 via the connecting plate 34. The copper wire guide assembly 3 is provided with a connecting rod assembly, a first bearing 31, a second bearing 33, a vertical bearing 32, and an elastic element. The connecting rod assembly is used to push the first bearing 31 and the second bearing 33 to fit tightly against the copper wire, which can reduce the vibration of the copper wire. The vertical bearing 32 is used to limit the jump of the copper wire in the Z-axis direction, thereby better fixing the position of the copper wire.

[0026] Elastic element connecting rod assembly.

[0027] In this example, the hose connector is used for quick connection and replacement of the vacuum cleaner or blower assembly; the vacuum hose 4 has a duckbill design to smoothly collect the paint removal fumes; the copper wire guide assembly 3 is used to fix the copper wire, reduce copper wire vibration, and improve paint removal accuracy.

[0028] In this example, the connecting plate 34 is equipped with diamond pins and cylindrical pins. The diamond pins and cylindrical pins are used for precise positioning.

[0029] In this example, screw holes are provided on the connecting plate 34.

[0030] In this example, the air hose is equipped with a clamp 51 and a mouthpiece 52.

[0031] Clamp 51 is used to secure the air hose to any selected hose connector.

[0032] In this example, the vacuum assembly 2 includes a vacuum hood 23, a front connecting plate 27, and a rear connecting plate 25. The front connecting plate 27 is disposed on the front surface of the vacuum hood 23, and the rear connecting plate 25 is disposed on the rear surface of the vacuum hood 23. The copper wire guide assembly 3 is disposed inside the vacuum hood 23. In this example, the front connecting plate 27, the rear connecting plate 25, and the vacuum hood 23 form a relatively enclosed space, effectively controlling the smoke and dust area. The internal vacuum hose 4 has a flared design, which optimizes airflow guidance, reduces escape, and improves vacuuming efficiency.

[0033] In this example, a gas flow sensor is installed at the hose interface.

[0034] In this example, the housing assembly is connected to the first hose interface 21, the second hose interface 24, the third hose interface 26, and the fourth hose interface 29 via four suction hoses 4, respectively. If the paint removal effect is not observed to be good, an air blowing hose is added according to the effect of paint removal. When an air blowing hose is added, the air blowing hose and the suction hose 4 form convection, which can quickly remove the smoke and dust generated during paint removal.

[0035] The specific operation process of this example is as follows: First, the copper wire to be de-coated is fixed on the copper wire guide assembly 3; by applying a thrust, the first bearing 31 and the second bearing 33 are pushed to fit tightly against the copper wire through the connecting rod assembly; at the same time, the laser de-coating device and the vacuum cleaner connected to the vacuum hose 4 are started to begin the laser de-coating and dust removal operation; after the de-coating is completed, the conveying mechanism transports the de-coated copper wire to the next station, and at the same time sends the next copper wire to be de-coated to the copper wire guide assembly 3.

[0036] Repeat the above process until all copper wires have undergone laser paint removal and dust removal.

[0037] In this example, the effect of laser paint removal is observed manually and by testing equipment. At the same time, the gas flow sensor detects the gas flow at the dust suction port in real time. When it is determined that the dust removal effect is poor due to insufficient gas flow, the laser paint removal dust removal is suspended, at least one dust suction hose 4 is removed, and an air blowing hose connected to the air supply equipment is installed.

[0038] It should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
