[0027] Please refer to Figure 1-8, the present invention provides a technical solution: a flexible wire automatic bending and automatic positioning welding device, including a main body frame 1, a workbench panel 2, a first opening 201, a placement groove 202, a first slide rail 3, a first cylinder assembly 4, a first push plate 5, a first bending block 6, a first pressing piece 7, a second cylinder assembly 8, a connecting frame 9, a second slide rail 10, a second push plate 11, an extrusion frame 12, a wire threading hole 1201, a second bending block 13, a second pressing piece 14, a wire harness length adjustment block 15, a second opening 1501, a bolt 1502, a follow-up fixture assembly 16, a chute 1601, a clamping block 1602, a clamping seat 1603, a spring 1604, a bracket 1605, a third opening 1606, a groove 1607, a bending groove 17, a limiting groove 18 and an inclined surface 19. A workbench panel 2 is arranged above the main body frame 1, and a first opening 201 is opened on the workbench panel 2. A placement groove 202 is arranged on the workbench panel 2. The left and right sides of the workbench panel 2 are symmetrically provided with a first slide rail 3, a first cylinder assembly 4 and a first push plate 5 respectively, and the first push plate 5 forms a telescopic structure through the first cylinder assembly 4. A first bending block 6 is slidably connected to one of the first slide rails 3, and a second bending block 13 is slidably connected to the other first slide rail 3, so as to be able to move the first bending block 6 and the second bending block 13 to realize the function of bending the wire harness and solve the problem of inconvenient manual positioning. A first pressing piece 7 is arranged on the first bending block 6. A connecting frame 9 is opened on the workbench panel 2, and a second cylinder assembly 8 is arranged on the connecting frame 9. A second slide rail 10 is installed on the connecting frame 9, and a second push plate 11 is installed on the second slide rail 10. The second push plate 11 is connected to an extrusion frame 12 below, and a wire threading hole 1201 is opened on the extrusion frame 12. A second bending block 13 is arranged on the right side of the connecting frame 9, and a second pressing piece 14 is installed on the second bending block 13. A wire harness length adjustment block 15 is arranged below the workbench panel 2, and a second opening 1501 is opened on the wire harness length adjustment block 15. A bolt 1502 is installed below the second opening 1501. A follow-up fixture assembly 16 is opened on the placement groove 202. A chute 1601 is arranged on the follow-up fixture assembly 16, and a clamping block 1602 is installed on the chute 1601. A clamping seat 1603 is arranged below the follow-up fixture assembly 16, and a spring 1604 is installed on the clamping block 1602. A bracket 1605 is arranged above the follow-up fixture assembly 16, and a third opening 1606 is opened on the bracket 1605. A groove 1607 is arranged on the bracket 1605. Bending grooves 17 are opened below both the first bending block 6 and the second bending block 13. Limiting grooves 18 are arranged on the bending grooves 17, and inclined surfaces 19 are opened at the bottoms of both the first pressing piece 7 and the second pressing piece 14.

[0028] The placement groove 202 is located in the middle of the workbench panel 2, and the accompanying fixture assembly 16 is installed on the placement groove 202 in an embedded manner, thereby realizing a limited installation of the accompanying fixture assembly 16, making the device more reasonable.

[0029] The size of the first pressing plate 7 is the same as that of the second pressing plate 14, and the surface of the bevel surface 19 is smooth to prevent the wire harness from being carried away after bending, making the device more stable in practical applications.

[0030] The second push plate 11 is connected to the second slide rail 10 in a sliding manner, and the second push plate 11 forms a lifting structure through the second cylinder assembly 8, which can clamp and relax the wire harness in conjunction with the accompanying clamp assembly 16, facilitating subsequent operations.

[0031] The connection between the bolt 1502 and the wire harness length adjustment block 15 is a threaded connection, and the central axes of the first opening 201, the threading hole 1201, the second opening 1501 and the third opening 1606 are all on the same vertical line, so that the length of the welding wire harness required can be adjusted to adapt to different working conditions.

[0032] The connection method of the clamping block 1602 on the slide groove 1601 is a sliding connection, and two groups of clamping blocks 1602 are arranged on the accompanying clamp assembly 16, and an elastic structure is formed between the clamping blocks 1602 through springs 1604. The elastic connection of the springs 1604 can clamp the wire harness when the extrusion frame 12 is separated from the clamping block 1602, preventing it from detaching during bending, making the device more stable and reasonable.

[0033] The third openings 1606 are arranged in two groups on the left and right sides of the accompanying clamp assembly 16 , and the third openings 1606 are arranged in a staggered manner, and the positions of the third openings 1606 correspond to the positions of the grooves 1607 .

[0034] The position of the bevel surface 19 corresponds to the position of the groove 1607, and the limiting groove 18 is V-shaped. The V-shaped limiting groove 18 is used to limit the wiring harness to prevent the subsequent bending from offsetting and causing unnecessary losses.

[0035] Working principle of this embodiment: When using this automatic soft wire bending and automatic positioning welding device, first, install the accompanying fixture assembly 16 inside the placement groove 202 on the workbench panel 2. Then start the second cylinder assembly 8 to drive the second push plate 11 to move up and down on the second slide rail 10 of the connecting frame 9, and squeeze the clamping block 1602 inside the accompanying fixture assembly 16 to contract inward through the extrusion frame 12 under the second push plate 11. At this time, the third opening 1606 is connected to the first opening 201 and the second opening 1501. Next, install the wire harness onto the device through the wire threading hole 1201, and there is a bolt 1502 below the second opening 1501. The length of the wire harness embedded is increased or decreased by the threaded connection between the bolt 1502 and the wire harness length adjustment block 15. After the installation is completed, push the second cylinder assembly 8 backward to separate the extrusion frame 12 from the clamping block 1602, and clamp the wire harness between the clamping block 1602 and the clamping seat 1603 through the elastic connection of the spring 1604 of the clamping block 1602.

[0036] Then place the aluminum shell to be welded on the bracket 1605. Then start the left and right first cylinder assemblies 4 to drive the first bending block 6 and the second bending block 13 on the first push plate 5 to move inward, and at the same time limit the wire harness through the limiting grooves 18 on the first bending block 6 and the second bending block 13. Subsequently, fix the wire harness on the groove 1607 through the inclined surfaces 19 under the first pressing piece 7 and the second pressing piece 14 to complete the bending. Finally, weld the wire harness and the aluminum shell through an external welding assembly. This is the entire working process. And the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
