Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a secondary positioning and flipping mechanism for cable routing and a shaping and welding production line.

The lateral pushing assembly includes a positioning abutment block that is slidably disposed on one side of the secondary positioning frame along the length direction. The positioning abutment block is close to the secondary positioning groove and has a tendency to elastically push against the clamping notch.

Detailed Implementation

[0020] Example 1, please refer to Figures 1 to 3 This is a schematic diagram of a secondary positioning and flipping mechanism for ribbon cables provided by this utility model. The secondary positioning and flipping mechanism includes: a secondary positioning frame 10; a secondary positioning platform 20 mounted on the secondary positioning frame 10; a secondary clamping block 22; and a lateral pushing assembly 30 used in conjunction with it. It is conceivable that this secondary positioning and flipping mechanism for ribbon cables also includes other functional components and specific structures, such as electrical connection components, control components, and installation structures, all of which are technologies known to those skilled in the art, and therefore will not be described in detail here.

[0021] In this embodiment, the secondary positioning frame 10 is an installation carrier, which is usually set on the machine or equipment platform to facilitate setting a suitable height and making it convenient for material transfer.

[0022] In this embodiment, the secondary positioning platform 20 is rotatably mounted on the secondary positioning frame 10. The secondary positioning frame 10 is equipped with an adjusting shaft 11, which is mounted on the secondary positioning frame 10 via bearings to achieve rotation. An adjusting driver 12, which is a motor, drives the adjusting shaft 11. The output end of the adjusting driver 12 is connected to the adjusting shaft 11 via a gear and pulley transmission. The secondary positioning platform 20 has a flat plate structure and rotates synchronously with the adjusting shaft 11. A recessed secondary positioning groove 21 is provided on the upper side of one side of the secondary positioning platform 20 for secondary positioning of the cable. The side wall of the secondary positioning groove 21 is used as a reference edge. The length of the cable protrudes beyond both ends of the secondary positioning groove 21, and the width of the cable is less than the width of the secondary positioning groove 21. One end face of the secondary positioning platform 20 is used as the other reference edge.

[0023] In this embodiment, a secondary positioning platform 20 is slidably connected to a secondary clamping block 22 via a guide rail. The secondary clamping block 22 is vertically lifting and lowering. The secondary clamping block 22 and the secondary positioning platform 20 are elastically connected by a downward pressure spring 24, forcing one end of the secondary positioning platform 20 to approach the inner upper end of the secondary positioning groove 21 and forming a clamping notch 23. The secondary clamping block 22 is connected to a secondary clamping driver 25, which is a driving cylinder, to move the secondary clamping block 22 away from the secondary positioning groove 21, thereby releasing the upper end of the secondary clamping block 22 from pressure. An angle adjusting block 13 is provided on the adjusting shaft 11, and a rotation limiting block 14 is provided on the secondary positioning frame 10 to restrict the rotation of the angle adjusting block 13. The rotation limiting block 14 and the angle adjusting block 13 cooperate to limit the rotation angle range of the adjusting shaft 11. In this embodiment, the rotation angle range is 90° from the horizontal state to the vertical state. It is conceivable that when the cable is fed into the secondary positioning slot 21, the secondary positioning platform 20 tilts and rotates with the adjusting shaft 11, and the cable automatically slides into the clamping notch 23, and then returns to a horizontal state, waiting for the alignment operation on the other side of the cable.

[0024] Optimally, the end of the secondary clamping block 22 is provided with a secondary clamping part 27 located above the clamping notch 23. The secondary clamping part 27 reduces the clamping area between the secondary clamping block 22 and the material on the feeding line, making the clamping more stable and reliable, and less prone to jamming.

[0025] In this embodiment, the lateral pushing assembly 30 includes a positioning abutment block 31 slidably disposed on one side of the secondary positioning frame 10 along its length. The positioning abutment block 31 is slidably disposed via a slide rail and is externally connected to a positioning abutment driver 34, which is a drive cylinder. The positioning abutment driver 34 controls the distance between the positioning abutment block 31 and the secondary positioning frame 10. The positioning abutment block 31 approaches the secondary positioning groove 21 and tends to elastically abut towards the clamping notch 23. Specifically, a abutment spring 33 is provided between the positioning abutment block 31 and the secondary positioning platform 20. When the positioning abutment driver 34 drives the positioning abutment block 31 to approach the secondary positioning groove 21, the abutment spring 33 causes the positioning abutment block 31 to elastically abut against the side wall of the cable, so that the cable is clamped in the clamping notch 23, achieving precise single-sided lateral abutment positioning and laying the foundation for subsequent lateral positioning on the other side. To release the lateral abutment lock, simply position the abutment driver 34 to drive the positioning abutment block to move away from the secondary positioning platform 20 on one side.

[0026] Ideally, the secondary positioning platform 20 is provided with a positioning clearance notch 26 at intervals on the side near the positioning abutment block 31. The positioning clearance notch 26 reduces the sliding contact area between the cable and the secondary positioning groove 21, making the movement smoother.

[0027] In this embodiment, the secondary positioning frame 10 is provided with secondary positioning limiting plates 35 at both ends of the secondary positioning platform 20 in the width direction. The secondary positioning plates limit the position range of the initial loading of the cable onto the secondary positioning platform 20. One of the secondary positioning limiting plates is provided with a side push block 32, which is externally connected to a drive cylinder, enabling the side push block 32 to slide along the width direction and act on one end of the clamping notch 23. When the output end face of the side push block 32 is flush with the end face of the secondary positioning platform 20 at the clamping notch 23, the positioning is completed after the cable end is pushed to be flush with the end face of the secondary positioning platform 20 at the clamping notch 23.

[0028] This invention achieves initial positioning by tilting the secondary positioning platform 20, and then completes lateral positioning by the side push block 32 after elastic contact between the upper end and one side, thus realizing secondary precise positioning after the material is taken out, providing a good positioning foundation for subsequent wiring connection welding.

[0029] It should be noted that the drive cylinder, motor, and sensor involved in this utility model are all commercially available parts and are existing technologies, so they will not be described in detail here.

[0030] Example 2: This utility model also provides a shaping and welding production line, which has the wire secondary positioning and flipping mechanism as described above. Except for the wire secondary positioning and flipping mechanism, the other components are all existing technologies or commercially available parts.

[0031] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
