Description

Technical Field

[0001] The utility model relates to a welding machine, in particular to an automatic welding machine for three-phase copper busbars. Background Art

[0002] The stator is a crucial component of an electric motor. It consists of three parts: the stator core, stator windings, and the frame. The stator's primary function is to generate a rotating magnetic field, while the rotor's primary function is to be cut by the magnetic lines of force within the rotating field, generating (or outputting) current.

[0003] During motor stator assembly, three copper busbars need to be mounted on the flat enameled wires within the stator. Since copper busbars cannot be directly welded to the flat enameled wires, the corresponding three-phase transfer busbars are first welded to the flat enameled wires within the motor stator. The three copper busbars are then welded to the corresponding transfer busbars. Currently, the process of welding the three copper busbars to the transfer busbars is mostly done manually, which results in slow processing speeds and inconsistent welding quality, making it unsuitable for production and processing needs.

[0009] A welding mechanism is provided above the carrier and is used to weld the copper busbar to the transfer copper busbar on the flat enameled wire;

[0010] A lifting and rotating module is provided below the carrier;

[0012] Furthermore, the carrier includes a carrying plate that can be laterally moved on the frame by being driven by the transplanting module; a placement cavity for adapting to the motor stator is provided on the carrying plate; and positioning holes for adapting to the lifting and rotating module are provided on both sides of the placement cavity.

[0014] Furthermore, the welding mechanism includes a welding seat; the welding seat is provided with a sliding seat that can move back and forth through a screw drive module; the sliding seat is provided with two relatively slidable left sliding mechanisms and right sliding mechanisms, and the left sliding mechanism and the right sliding mechanism are provided with relatively arranged left welding units and right welding units.

[0018] The automatic welding machine for three-phase lines of the present invention first limits the three copper bars in the motor stator, and the three copper bars are in contact with the corresponding transfer copper bars. Then, the transplanting module moves the carrier carrying the motor stator to the lifting and rotating module. The lifting and rotating module cooperates with the welding mechanism to weld the three copper bars to the corresponding transfer copper bars in turn.

DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0031] For ease of understanding, the specific process in the embodiment of this application is described below. Figures 1 to 2 In an embodiment of the present application, an automatic welding machine for a three-phase copper busbar includes a transplanting module 2, a carrier 3, a copper busbar positioning portion 4, a welding mechanism 5, and a lifting and rotating module 6 arranged on a frame 1; the carrier 3 is driven by the transplanting module 2 to be laterally transplanted on the frame 1, and the carrier 3 is used to load the motor stator 10; the copper busbar positioning portion 4 is arranged at the upper end of the motor stator 10 in the carrier 3, and is used to position the copper busbar on the transfer copper busbar 12 of the flat enameled wire 11 of the motor stator 10 in the carrier 3; the welding mechanism 5 is arranged above the carrier 3, and is used to weld the copper busbar to the transfer copper busbar 12 of the flat enameled wire 11; the lifting and rotating module 6 is arranged below the welding mechanism 5.

[0032] In the automatic welding machine for three-phase copper busbars of the present invention, when the transplanting module 2 drives the carrier 3 carrying the motor stator 10 to be transplanted above the lifting and rotating module 6, the lifting and rotating module 6 lifts and rotates the carrier to cooperate with the welding mechanism 5 to weld the copper busbar to the transfer copper busbar 12 of the flat enameled wire 11, thereby automatically realizing the operation of welding the copper busbar to the motor stator, with high welding efficiency and quality, and saving labor costs.

[0033] based on Figure 1 and Figure 3 In this embodiment, the carrier 3 includes a carrier plate 30. The carrier plate 30 is driven by the transfer module 2 to move laterally on the frame 1. The carrier plate 30 is constrained left and right on the transfer module 2, but can be raised and lowered in the Z direction. In this way, the carrier plate 30 can be driven by the lifting and rotating module 6 to perform Z-direction lifting and rotation operations in the transfer module 2. The carrier plate 30 is provided with a placement cavity 31 for accommodating the motor stator 10. During use, the motor stator 10 is placed in the placement cavity 31.

[0034] In addition, the carrier plate 30 is provided with two positioning holes 32 which are arranged opposite to each other. The positioning holes 32 cooperate with the lifting and rotating module 6. When the lifting and rotating module 6 is inserted into the positioning holes 32, the lifting and rotating module 6 can drive the carrier plate 30 to rotate and lift.

[0035] based on Figures 3 to 5In this embodiment, the copper busbar positioning portion 4 includes a mounting frame 40 arranged along the upper edge of the motor stator 10; the mounting frame 40 is provided with two columns 42, and the upper ends of the two columns 42 are provided with a horizontally arranged positioning block 43, and the positioning block 43 is installed above the mounting frame 40. The positioning block 43 is provided with three vertically arranged limiting components, which respectively correspond to the three-phase transfer copper busbar 12, namely the U-phase transfer copper busbar, the V-phase transfer copper busbar and the W-phase transfer copper busbar. The limiting component includes a placement plate 44 vertically arranged on the positioning block 43, and the placement plate 44 is provided with two limiting grooves 45 respectively located above and below the positioning block 43, and the two limiting grooves 45 are aligned with the left and right references, and the bottom of the limiting groove 45 is arranged corresponding to the three-phase transfer copper busbar 12 above and below.

[0036] Specifically, the limiting grooves 45 on the two limiting components have the same orientation, and the limiting groove 45 on the other limiting component has a different orientation from the other two. The orientation settings can be adaptively adjusted according to different specifications of products.

[0037] In addition, two handles 41 are provided on the mounting bracket 40 , so as to facilitate the disassembly and installation of the mounting bracket 40 on the motor stator 10 .

[0038] During operation, when it is necessary to weld the copper busbar and the transfer copper busbar, first insert the three copper busbars to be welded into the two limit slots 45 corresponding to the corresponding three limit assemblies, and make the three copper busbars contact with the corresponding three-phase transfer copper busbars respectively, so as to facilitate the subsequent welding mechanism 5 to weld the transfer copper busbar and the copper busbar.

[0039] As a preferred embodiment, based on Figure 8 In the embodiment, the welding mechanism 5 includes a welding seat 50; the welding seat 50 is provided with a sliding seat 52 which can move forward and backward through a screw drive module 51; the sliding seat 52 is provided with two relatively slidable left sliding mechanisms 53 and right sliding mechanisms 54, and the left sliding mechanisms and the right sliding mechanisms are provided with relatively arranged left welding units 55 and right welding units 56.

[0040] At the same time, in order to ensure that the relative sliding distance positioning of the left sliding mechanism 53 and the right sliding mechanism 54 is accurate, a first positioning rod 57 and a second positioning rod 58 are respectively provided on the left sliding mechanism and the right sliding mechanism; when the second positioning rod 58 is inserted into the corresponding position of the first positioning rod 57, it means that the sliding position of the left sliding mechanism and the right sliding mechanism is in place, then the left sliding mechanism and the right sliding mechanism will no longer continue to slide, and the left welding unit 55 and the right welding unit 56 will weld the copper busbar and the transfer copper busbar 12.

[0041] As a preferred embodiment, based on Figures 6 and 7In this embodiment, the lifting and rotating module 6 includes a lifting base 60; the lifting base 60 is provided with a transverse slide 62 that can be laterally moved on the lifting base 60 via a transverse screw moving module 61. The transverse slide 62 is provided with four guide posts 63; the four guide posts 63 are provided with a lifting frame 65 that is driven to move the transverse slide 62 up and down in the Z direction via a Z-direction screw moving module 64. The lifting frame 65 is provided with a mounting seat 66; a rotary motor 67 is housed within the mounting seat 66; the rotary shaft of the rotary motor 67 extends through the top of the mounting seat 66 and is connected to a rotating plate 68; the rotating plate 68 is provided with two positioning posts 69 that are adapted to the two positioning holes.

[0042] During operation, when the carrier 3 moves to the corresponding position of the lifting and rotating module 6, the lifting and rotating module 6 starts to work, and when the horizontal screw moving module 61 drives the lifting frame 62 to move horizontally to the set position, the Z-direction screw moving module 64 drives the lifting frame 65 to move upward under the guidance of the guide column 63. When it moves to a certain position on the guide column 63, the two positioning columns 69 on the rotating plate 68 are just inserted into the two positioning holes 32 on the carrier 3, so that the lifting frame 65 is connected to the carrier 3. When the rotating motor 67 rotates, the carrier 3 is driven to rotate synchronously through the rotating plate 68, so that the lifting and rotating module 6 realizes the jacking and rotation operation of the carrier 3.

[0043] Furthermore, a material receiving module 7 is also provided on one side of the transplanting module 2 of the automatic welding machine for automatically transmitting the processed motor stators, thereby improving production efficiency.

[0044] Furthermore, it also includes a control panel 8 for controlling the automatic welding machine, and the relevant operations of the automatic welding machine are debugged and controlled through the control panel 8.

[0045] During actual processing, the three-phase transfer copper bars 12 have been welded to the flat enameled wires 11 of the motor stator 10 , so it is necessary to weld three copper bars to the corresponding three-phase transfer copper bars 12 .

[0046] The processing flow is as follows: first, the motor stator 10 is placed into the placement cavity 31 for positioning, and then the three copper bars are placed on the corresponding three-phase transfer copper bars 12 in a limited manner through the limiting grooves 45.

[0047] Then the transplanting module 2 drives the carrier carrying the electronic stator 10 to move horizontally on the frame. When the carrier 3 moves to the position corresponding to the lifting and rotating module 6, the carrier 3 stops moving.

[0048] The transverse screw moving module 61 in the lifting and rotating module 6 drives the lifting frame 62 to move transversely to the set position, and the Z-direction screw moving module 64 drives the lifting frame 65 to move upward under the guidance of the guide column 63 until the two positioning columns 69 on the rotating plate 68 are just inserted into the two positioning holes 32, so that the lifting frame 65 is connected to the carrier 3, and then the Z-direction screw moving module 64 continues to drive the carrier to move upward to the set welding height.

[0049] After the height positions of the first copper bar and the transfer copper bar are driven, the rotary motor 67 starts to work and rotates the first copper bar and the transfer copper bar to the set welding position.

[0050] The left welding unit 55 and the right welding unit 56 in the welding mechanism 5 move forward to a set position, so that a copper busbar and a transfer copper busbar are located between the left welding unit 55 and the right welding unit 56 .

[0051] The left welding unit 55 and the right welding unit 56 move synchronously relative to each other to a set position to weld a copper busbar and a transfer copper busbar together. After welding is completed, the left welding unit 55 and the right welding unit 56 return to their original positions.

[0052] The lifting and rotating module 6 drives the second copper bar and the transfer copper bar as well as the third copper bar and the transfer copper bar to lift and rotate to the set position in turn, and then the left welding unit 55 and the right welding unit 56 continue to weld the interface, thereby completing the copper bar welding of the three phases of the motor stator.

[0053] In summary, the automatic three-phase wire welding machine of the present invention can quickly and effectively weld three copper bars to the transfer copper bar on the flat enameled wire located in the motor stator, with high processing efficiency and quality, meeting the needs of large-scale production of enterprises.

[0054] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
