Description

Technical Field

[0001] This utility model relates to the field of automated manufacturing equipment technology, and in particular to a rotary table type continuous bending device for wire laying. Background Technology

[0002] In the field of electronic components and wire harness assembly, the precision bending of ribbon cables is a key process affecting the compactness of product structure and the reliability of electrical connections. As electronic devices become smaller and more integrated, the bending forms of ribbon cables are becoming increasingly complex, often requiring multiple bends of different directions and angles to be formed on the same part. Current technology employs a step-by-step bending method for such multi-bend ribbon cables, where bending operations in different directions are completed sequentially at independent workstations. This method has the following drawbacks: First, because the workpiece needs to be transferred and repeatedly positioned between different workstations, it not only results in long cycle times and low efficiency, but also increases the complexity and floor space of the equipment. Furthermore, it is prone to cumulative errors due to multiple clamping operations, making it difficult to guarantee the relative positional accuracy between the bends, directly affecting the assembly consistency of the product. Second, traditional bending equipment is mostly single-action mode; a single die can typically only complete bending in one direction. For complex ribbon cables with multiple continuous bends, multiple sets of dedicated dies are often required and switched sequentially, resulting in high costs for die management and changeover adjustments.

[0037] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0038] like Figure 1 As shown, the rotary type continuous bending device for wiring according to this utility model includes a rotary turntable 100, a carrier 200 on the rotary turntable 100 for carrying multiple workpieces 1, and a bending mechanism configured corresponding to the bending station.

[0039] like Figure 2 and Figure 3 The bending mechanism includes a bending frame 300, an upper bending execution module 400, and a lower bending execution module 500. The bending frame 300 is disposed on the outer periphery of the rotary disk, and the upper bending execution module 400 includes multiple sets of upper bending drive units arranged at intervals on the bending frame 300, and upper bending execution components respectively installed on the drive ends of each upper bending drive unit.

[0040] Each set of upper bending drive units includes a first bending drive component 410 fixed on the bending frame 300 and a second bending drive component 420 obliquely mounted on the driving end of the first bending drive component 410. The upper bending execution component is connected to the output end of the second bending drive component 420 through a mounting base.

[0041] In this embodiment, the first bending drive 410 is an X-axis sliding platform used to drive the upper bending execution component to move in the vertical direction. The second bending drive 420, in cooperation with the XY-axis sliding platform, realizes the lateral precision bending action of the upper bending execution component.

[0042] The upper bending execution assembly includes an upper bending head 430, which is connected to a mounting base via a first floating mechanism 440. The first floating mechanism 440 includes a mounting support 441 fixed to the mounting base, a first fastener passing through the mounting support 441, and a first elastic member 442 sleeved around the outer periphery of the first fastener. The axial direction of the first fastener is consistent with the bending feed direction of the upper bending head 430, and its end is threadedly connected to the sliding portion of the upper bending head 430. Both ends of the first elastic member 442 abut against the mounting support 441 and the sliding portion, respectively, so that the first fastener and the mounting support 441 form a sliding fit.

[0043] The mounting base is provided with a first linear slide rail 443 extending along the bending feed direction. When the upper bending head 430 is compressed during the bending process, its sliding part can float slightly along the first linear slide rail 443 and compress the first elastic element 442, thereby realizing flexible compression and adaptive compensation for position deviation.

[0044] like Figure 4 and Figure 5 The end working part of the upper bending head 430 integrates a bending punch and a support platform 435.

[0045] The bending punch includes a first guide slope 431, a first forming concave arc surface 432 that transitions to the upper end of the first guide slope 431, and a forming tip 433 that transitions to the lower end of the first guide slope 431.

[0046] like Figure 6 The material loading position of the carrier 200 is provided with a positioning support mold on the side opposite to the upper bending head 430. The positioning support mold includes a support side wall 210. The upper end of the support side wall 210 is transitionally connected to the placement plane of the workpiece 1 and forms a positioning angle 220. The lower end of the support side wall 210 is transitionally connected to a second forming concave arc surface 230. The angle of the positioning angle 220 is consistent with the target angle of the first bending part 11 of the workpiece 1. The radius of curvature of the second forming concave arc surface 230 is adapted to the target inner diameter of the second bending part 12 of the workpiece 1.

[0047] When the bending punch moves along the feed direction, its first guide slope 431 slides against the support side wall 210 and squeezes the workpiece 1 to bend it until the first forming concave arc surface 432 and the positioning angle 220 form a compression interlock, thus completing the forming of the first bending part 11; at the same time, the forming tip 433 and the second forming concave arc surface 230 are completely attached and abut against each other, thus completing the forming of the second bending part 12.

[0048] The back side of the first guide slope 431 is a support back surface 434. The support back surface 434 and the support platform 435 are connected by a third shaped concave arc surface 436. The radius of curvature of the third shaped concave arc surface 436 is adapted to the target inner diameter of the third bending part 13 of the workpiece 1.

[0049] like Figure 7 and Figure 8 The lower bending execution module 500 includes a bending bracket and multiple sets of lower bending drive components 510 arranged at intervals and fixed on the bending bracket. The bending bracket extends toward the rotary table 100 and is located below the rotary table 100. The drive end of each lower bending drive component 510 is connected to the lower bending execution assembly through the lower bending cutter holder 520.

[0050] In this embodiment, the downward bending drive component 510 is a drive motor, and the output end of the drive motor is connected to a lead screw transmission structure 530. The lead screw transmission structure 530 includes a lead screw driven to rotate by the drive motor and a lead screw nut that cooperates with the lead screw. The downward bending cutter holder 520 is fixedly connected to the lead screw nut and, under the drive of the corresponding downward bending drive component 510, drives the downward bending assembly to move in the vertical direction.

[0051] Furthermore, the bending bracket is provided with a guide plate 540 extending in the vertical direction, and the lower bending cutter holder 520 is sleeved on the guide plate 540 and can slide along it, thereby providing guidance and anti-torsional support for the vertical movement of the lower bending cutter holder 520.

[0052] The downward bending execution component includes a horizontal fine-tuning component 550 and a downward bending head 560 disposed at the output end of the horizontal fine-tuning component 550. The downward bending head 560 is disposed adjacent to the positioning support mold of the carrier 200. Its top working part is provided with a forming apex angle 561. The angle of the forming apex angle 561 is consistent with the target angle of the third bending part 13 of the workpiece 1. A second guide slope 562 and a third guide slope 563 are respectively formed on both sides of the forming apex angle 561.

[0053] After the first bending portion 11 and the second bending portion 12 are formed, the upper bending head 430 remains stationary and presses against the workpiece 1. The lower bending head 560 is driven by the drive motor to perform bending feed motion in the vertical direction until the second guide inclined surface 562 and the support back surface 434 are fully engaged. At this time, the free end of the workpiece 1 gradually covers the bending punch, and the forming apex 561 and the third forming concave arc surface 436 are fully engaged and abut against each other, completing the forming of the third bending portion 13. Figure 9 and Figure 10 .

[0054] like Figure 11 The horizontal fine-tuning component 550 is used to adjust the gap between the lower bending head 560 and the carrier 200. It includes an adjusting base 551 fixed on the lower bending cutter holder 520, a sliding seat 552 slidably disposed on the adjusting base 551, and a second fastener 553 for locking the sliding seat 552. The adjusting base 551 has a sliding groove 554 extending horizontally toward the carrier 200. The sliding seat 552 cooperates with the sliding groove 554 through the second fastener 553 and can be adjusted in position along its extension direction. The sliding seat 552 has an oblong hole, and a third fastener passes through the oblong hole to connect the sliding seat 552 to the adjusting base 551.

[0055] Furthermore, such as Figure 12 and Figure 13A positioning mechanism 600 is provided above the carrier 200. The positioning mechanism 600 includes a positioning drive 610, a support plate 620 driven by the drive, and a cooperative positioning unit mounted on the support plate 620.

[0056] The collaborative positioning unit includes two positioning pins 630 and multiple positioning pressure heads 640. The two positioning pins 630 are distributed at both ends of the bearing plate 620 along the length of the carrier 200 and cooperate with the positioning pin holes provided on the carrier 200 to achieve precise positioning of the carrier 200 at the bending station.

[0057] Each positioning head 640 corresponds to each workpiece 1. When the positioning drive 610 is activated, the bearing plate 620 drives the two positioning pins 630 to first insert into the positioning pin holes to complete the positioning of the carrier 200. Then, the positioning head 640 continues to move down with the bearing plate 620 and presses against the corresponding workpiece 1, thereby effectively preventing the workpiece 1 from shifting during the bending process.

[0058] Furthermore, a second floating mechanism 650 is provided between the positioning pressure head 640 and the support plate 620. The second floating mechanism 650 includes a second linear slide rail 651 mounted on the support plate 620, a fourth fastener threadedly connected to the positioning pressure head 640, and a second elastic element 652 sleeved on the outer periphery of the fourth fastener. The second linear slide rail 651 extends vertically, and a mounting block 653 is fixedly mounted on the support plate 620 above the positioning pressure head 640. The fourth fastener passes through the mounting block 653 vertically and slides with it. The two ends of the second elastic element 652 abut against the positioning pressure head 640 and the mounting block 653, respectively. When the positioning pressure head 640 descends and contacts the workpiece 1, it floats slightly along the second linear slide rail 651 under the elastic force of the second elastic element 652, achieving flexible contact between the positioning pressure head 640 and the workpiece 1 and avoiding damage to the workpiece 1.

[0059] In this embodiment, a mounting frame 660 extending toward the rotary turntable 100 is fixedly provided on the support frame, and the positioning mechanism 600 is installed on the mounting frame 660 so that the positioning pin 630 and the positioning pressure head 640 can be aligned with and act on the carrier 200 and the workpiece 1 on the lower turntable.

[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
