Description

Technical Field

[0001] The present invention belongs to the technical field of motor production equipment, and in particular relates to a line folding device for lead wires of a new energy motor line group. Background Art

[0002] The structure of the motor wiring assembly for new energy vehicles is complex. During production, the copper wire is first cut into segments of a certain length. Then, after steps such as paint stripping, U-folding, and 3D molding, a U-shaped wire is formed. The U-shaped wire is inserted into the motor stator, forming a multi-layer winding on the motor stator. Finally, the motor wiring assembly is obtained by welding. There are generally three pairs of three-phase lead wires on the winding. After the U-shaped wire is inserted, the lead wires are closely attached to the other wires. Due to process requirements, they need to be bent at a certain angle to distinguish them from the other wires in the winding and facilitate subsequent motor assembly operations. Manually bending the lead wire ends is obviously time-consuming and laborious, and the bending effect is difficult to control, resulting in poor product consistency. Therefore, it is necessary to design a bending device that can automatically bend the lead wire ends based on the characteristics of the new energy vehicle motor wiring assembly structure.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0021] like Figure 1-5 As shown, the new energy motor wire group lead wire folding device includes a tray mechanism and a folding mechanism.

[0022] The tray mechanism includes a rotating tray 1, a fixed frame 2, and an inner mold 3. A bracket 4 is provided in the middle of the rotating tray 1, and a center hole 5 is provided in the middle of the bracket 4. The rotating tray 1 is rotatably mounted on the fixed frame 2. A rotating drive mechanism for driving the rotating tray 1 to rotate is installed on the fixed frame 2. The inner mold 3 is located in the bracket 4. The inner mold 3 is driven to rise and fall by a lifting drive mechanism. A plurality of inner grooves 6 are provided around the inner mold 3.

[0023] The folding mechanism includes a clamping jaw 7 and a tilting telescopic arm 8. The clamping jaw 7 is installed at the lower end of the tilting telescopic arm 8. The tilting telescopic arm 8 is driven by a telescopic drive mechanism to move in an inclined manner, and the tilting telescopic arm 8 is driven by an up and down movement drive mechanism to move in an up and down manner. The rotating tray 1 drives the motor 31 to rotate, so that the lead wire end 30 moves to a specified position, and then the tilting telescopic arm 8 tilts down, so that the clamping jaw 7 grabs the lead wire end 30. The clamping jaw 7 grabs the lead wire end 30 and bends it so that it is stuck in the inner groove 6 on the inner mold 3. The bending angle of the lead wire end 30 is fixed. After the bending is completed, the inner mold 3 descends, and the rotating tray 1 drives the motor 31 to rotate a certain angle to fold another lead wire end 30.

[0024] Furthermore, an upper mold 9 is provided just above the rotating tray 1, and a plurality of upper mold grooves 10 are provided around the lower end of the upper mold 9. The upper mold 9 is driven to rise and fall by a mold drive mechanism. After the folding line is completed, since the clamping claws 7 clamp the lead wire ends 30 for bending, only the inner mold grooves 6 of the inner mold 3 on the other side restrict the forming of the lead wire ends 30, and the folding line forming of the lead wire ends 30 may not be in place. After all the lead wire ends 30 are folded, the upper mold 9 descends, and the upper mold 9 is used to apply pressure to the bent lead wire ends 30 so that they are stuck in the upper mold grooves 10, and the lead wire ends 30 are finalized.

[0025] Furthermore, the rotary drive mechanism includes a gear ring 11, a gear 12, and a rotary motor 13. The gear ring 11 is fixedly connected to the rotating tray 1 and is coaxially arranged with the rotating tray 1. The gear 12 meshes with the gear ring 11. The rotary motor 13 is mounted on the fixed frame 2 and drives the gear 12 to rotate. The rotary motor 13 drives the gear ring 11 to rotate through the gear 12, thereby driving the rotating tray 1 to rotate, and the motor 31 on the rotating tray 1 rotates accordingly.

[0026] Furthermore, the lifting drive mechanism includes a linear motor 14, connected to the lower end of the inner mold 3 via a connecting rod 15. After the motor 31 is placed on the rotating tray 1, the linear motor 14 drives the inner mold 3 upward until it reaches a specified height, whereupon the inner mold 3 cooperates with the folding mechanism to fold the mold. Once the folding is complete, the inner mold 3 descends, allowing the rotating tray 1 to drive the motor 31.

[0027] Furthermore, the telescopic drive mechanism includes a tilted linear motor 16, which drives the tilted telescopic arm 8 to move. The up and down movement drive mechanism includes a support plate 17 and an upper and lower linear motor 18. The upper and lower linear motor 18 drives the support plate 17 to move up and down, and the tilted linear motor 16 is tiltedly installed on the support plate 17. The upper and lower linear motor 18 drives the clamp 7 to move up and down. When the motor rotates to adjust the angle, the clamp 7 rises and avoids the motor. When the motor is in place, the clamp 7 descends and grabs the specified lead wire end. After the clamp 7 grabs the lead wire end 30, the tilted linear motor drives the tilted telescopic arm 8 to move, so that the clamp 7 pushes the lead wire end 30 to bend. After the bending is completed, the clamp 7 releases the lead wire end 30 and the clamp 7 rises.

[0028] Furthermore, a product conveyor line 19 is provided on one side of the fixed frame 2, and a slide rail 20 and a mounting plate 21 are provided above the fixed frame 2. The slide rail 20 extends above the product conveyor line 19, and the mounting plate 21 is slidably mounted on the slide rail 20. The mounting plate 21 is driven by a translational drive mechanism to move on the slide rail 20. A manipulator is provided below the mounting plate 21, and the manipulator is driven up and down by a vertical movement drive mechanism installed on the mounting plate 21. The motor to be folded is transported on the product conveyor line 19, and the manipulator grabs the motor from the product conveyor line 19 and then transfers it to the rotating tray 1. After the motor folding is completed, the manipulator transfers the folded motor back to the product conveyor line 19.

[0029] Furthermore, the manipulator is fixed to a manipulator fixing plate 22. Linear slide rails 23 are fixedly connected to both sides of the manipulator fixing plate 22. Linear sliders 24 are mounted on the linear slide rails 23. The linear sliders 24 are fixedly mounted on the mounting plate 21. The vertical movement drive mechanism includes a vertical linear motor 25. The translation drive mechanism includes a translation motor 26. A rack 27 is mounted on the slide rail 20. A rotating gear is engaged with the rack 27. The translation motor 26 drives the rotating gear to rotate. The translation motor 26 is fixedly connected to the mounting plate 21. The translation motor 26 drives the entire mounting plate 21 to move on the slide rail 20 by driving the rotating gear to rotate, thereby transferring the motor between the product conveyor line 19 and the rotating tray 1. The vertical linear motor 25 drives the manipulator up and down to grab the motor.
