[0007] As a further improvement of the above technical solution:

[0008] The ends of the bending parts of the two shaping jaws extend towards each other to form a protruding part. When the opposite end faces of the protruding parts are in contact, an interval distance is formed between the opposite side faces of the shaping jaws outside the protruding parts, and the wire ends of the wire harness are clamped and placed in the interval distance, and the interval size of the interval distance is larger than the diameter size of the wire ends of the wire harness.

[0009] The cross section of the protruding part gradually decreases towards the direction of the end face, the end face is a plane, and the connecting surfaces at the edges of the end face are all inclined planes.

[0010] The bending jaws are of a straight jaw structure with a gradually decreasing cross section.

[0012] The vehicle is disposed obliquely towards the pressure maintaining mechanism. The vehicle includes a pressing plate and a bottom plate stacked in the thickness direction. The wire harness is pressed between the pressing plate and the bottom plate, and the wire end of the wire harness passes through the through hole of the pressing plate. A forming plate is installed on the side wall of the through hole. A concave hole is formed at the edge of the forming plate facing the bottom plate, and the wire end is limited in the concave hole.

[0019] The manipulator drives the bending component to move to the wire end of the wire harness. The bending claws clamp the pre-bent wire end, and the action of the manipulator drives the wire end to continue to bend in the direction of the pre-bending;

[0020] The wire harness moves along the translation module with the vehicle to the pressure maintaining mechanism, and the pressure maintaining mechanism applies pressure to the wire end of the bent wire harness for a preset time.

[0043] The following combines the drawings to illustrate the detailed implementation mode of the present invention.

[0044] As Figure 1 and Figure 2 shown, the flexible wire harness bending automation equipment of this embodiment includes a translation module 1, a transfer seat 2 is installed on the translation module 1, a carrier 3 is supported on the transfer seat 2, and a wire harness 10 is clamped on the carrier 3; outside the translation module 1, there are arranged a manipulator 8, a pressure holding mechanism 4, and a detection assembly. A bending assembly 6 and a shaping assembly 7 are installed at the end of the manipulator 8; the shaping assembly 7 includes shaping grippers 71 that are driven by a finger cylinder to move towards or away from each other, and a bending part 72 extends from the shaping grippers 71 away from the moving plane; the bending assembly 6 includes bending grippers 61 that are driven by a finger cylinder to move towards or away from each other.

[0045] In this embodiment, the shaping assembly 7 pre-bends the end of the wire harness 10, then the bending assembly 6 bends it, and the pressure holding mechanism 4 holds the bent part of the end, realizing the automation of the wire harness 10 bending.

[0046] In this embodiment, by extending the bending part 72 on the shaping grippers 71, the reliable force application during the pre-bending of the end of the wire harness 10 can be effectively ensured via the bending part 72, which helps to guarantee the overall bending effect, especially reducing or even avoiding damage to the end during the bending process.

[0047] As Figure 2 and Figure 3As shown, the ends of the bending parts 72 of the two shaping jaws 71 extend towards each other to form protruding parts 73. When the facing end faces 74 of the protruding parts 73 are in contact, a spacing distance is formed between the facing side surfaces of the shaping jaws 71 outside the protruding parts 73. The wire ends of the wire harness 10 are clamped and placed at the spacing distance, and the spacing dimension of the spacing distance is larger than the diameter dimension of the wire ends of the wire harness 10.

[0048] In this embodiment, as Figure 5 shown, when the shaping jaws 71 are clamped on both sides of the wire harness 10 and a pre-bending force is applied to the wire harness 10, the wire harness 10 is in a free state without being clamped and is inserted and placed at the spacing distance. The protruding parts 73 with the end faces 74 in contact limit the detachment of the wire harness 10; during the pre-bending force application process, as the manipulator 8 moves, the wire ends of the wire harness 10 are passively bent under the restriction of the protruding parts 73 with the end faces 74 in contact, as Figure 6 shown, to achieve pre-bending.

[0049] In this embodiment, before pre-bending, the shaping jaws 71 extend to the position where the wire harness 10 is to be bent, such as Figure 5 the root of the wire end shown.

[0050] In this embodiment, the setting of pre-bending effectively solves the problem that the wire ends of the wire harness 10 are inconvenient to clamp when extending along the carrier 3 before bending. By using the shaping jaws 71 provided with the bending parts 72 and the protruding parts 73, pre-bending is achieved, making the wire ends far from the carrier 3, facilitating the bending operation; and by combining the protruding parts 73 applying a passive force to the wire ends to bend them, clamping damage is reduced or even avoided.

[0051] The cross-section of the protruding part 73 gradually decreases in the direction towards the end face 74. The end face 74 is a plane, and the connecting faces at the edges of the end face 74 are all inclined planes; while ensuring the smooth progress of pre-bending, the damage to the wire harness 10 is reduced, and through the setting of the inclined planes, when the wire harness 10 contacts and is stressed by the inclined planes on the side surfaces of the protruding part 73, it promotes the pre-bending of the wire harness 10 and makes it gather towards the middle, ensuring the centering of the bending, especially suitable for multi-core wire harnesses.

[0052] As Figure 4 shown, the bending jaw 61 has a straight jaw structure with a gradually decreasing cross-section.

[0053] During use, the bending jaw 61 clamps the wire ends of the wire harness 10 after pre-bending, and the manipulator 8 drives the bending jaw 61 to swing along the bending direction, thereby achieving the bending of the wire harness 10, as Figure 7 and Figure 8 shown.

[0054] In this embodiment, after pre-bending, the wire head is bent and deviated from the carrier 3, which facilitates the clamping by the straight claw of the bending jaw 61, and the bending can be realized by the synchronous swing of the wire head with the bending jaw 61, effectively avoiding the relative movement friction after the bending jaw 61 clamps the wire head of the wire harness 10.

[0055] The pressure maintaining mechanism 4 and the manipulator 8 are arranged on both sides of the translation module 1. The manipulator 8 is a six-axis robot, and the overall layout is compact.

[0056] As Figure 9 and Figure 10 shown, the carrier 3 is arranged obliquely towards the pressure maintaining mechanism 4. The carrier 3 includes a pressing plate 32 and a bottom plate 31 stacked in the thickness direction. The wire harness 10 is press-fitted between the pressing plate 32 and the bottom plate 31, and the wire head of the wire harness 10 penetrates through the through hole of the pressing plate 32, which facilitates the bending operation of the wire head.

[0057] In this embodiment, a forming plate 33 is installed on the side wall of the through hole. The forming plate 33 is provided with a concave hole 331 towards the edge of the bottom plate 31, and the wire head is limited in the concave hole 331, which helps to ensure the development of bending.

[0058] In this embodiment, the setting of the forming plate 33 can also be used as the force bearing during pressure maintaining; by setting the angle of the forming plate 33, it matches the bending angle of the wire head of the wire harness 10.

[0059] In Figure 9 the embodiment shown, the structure of the pressure maintaining mechanism 4 is: including a linear driving power one 42 obliquely installed on the side of the support 41, a linear driving power two 43 is installed on the output part of the linear driving power one 42, a linear driving power three 45 is installed on the output part of the linear driving power two 43 through a moving plate 431, a pressing block 49 is floatingly installed on the output part of the linear driving power three 45, and the pressing block 49 presses on the wire head after the wire harness 10 is bent; a pneumatic gripper 44 is also installed on the moving plate 431 through a support plate 441, and two gripper claws 440 on the output part of the pneumatic gripper 44 are arranged on both sides of the wire harness 10.

[0060] As Figure 11 shown, during pressure maintaining, the two gripper claws 440 hold on both sides of the wire head of the wire harness 10, and the pressing block 49 applies a downward force on the wire head. By setting the preset pressure and preset time, the bending effect of the wire head is ensured and maintained; it is especially suitable for the bending of multi-core cables.

[0061] The power output direction of the linear driving power one 42 is perpendicular to the carrier 3, driving the pressing block 49 to approach or move away from the carrier 3; the power output directions of the linear driving power two 43 and the linear driving power three 45 are parallel to the carrier 3, driving the pressing block 49 to fit on the top surface of the carrier 3 and approach or move away from the wire harness 10.

[0062] In this embodiment, the movement of the linear drive power two 43 drives the pressure block 49 and the upper claws 440 of the pneumatic gripper 44 to move synchronously towards the wire harness 10 until the claws 440 are located on both sides of the wire harness 10. Through the operation of the pneumatic gripper 44, the claws 440 approach each other and are close to both sides of the wire harness 10. Then, the movement of the linear drive power three 45 drives the pressure block 49 to move closer to, abut against, and apply force to the bent end of the wire harness 10 for pressure holding.

[0063] In this embodiment, the linear drive power one 42, the linear drive power two 43, and the linear drive power three 45 can all adopt slide table cylinders. Of course, in actual use, other power sources capable of outputting linear drive can also be used as long as they can achieve pressure holding.

[0064] A pressure holding plate 46 is installed on the output part of the linear drive power three 45. The pressure holding plate 46 is slidably installed with a pressure block 49 through a slide rail 47. A support block 481 is also installed on the pressure holding plate 46. A pressure sensor 9 is installed on the bottom surface of the support block 481. An elastic member 48 is installed between the pressure sensor 9 and the pressure block 49 to form a floating installation of the pressure block 49.

[0065] When the linear drive power three 45 operates, the pressure block 49 approaches and contacts the end of the wire until the pressure block 49 abuts against a support member, such as the forming plate 33, below the bent part of the end of the wire. With the continuous operation of the linear drive power three 45, the elastic member 48 is compressed, and the pressure sensor 9 provides real-time feedback of the pressure. By combining the pressure with the holding time, the pressure holding of the bent end of the wire by the pressure block 49 is realized.

[0066] In this embodiment, the pressure block 49 can be made of a flexible material, such as rubber coating, to avoid damaging the end of the wire during pressure holding contact.

[0067] In this embodiment, the end of the wire harness 10 can be bent at 90°. The plane of the forming plate 33 is perpendicular to the layout of the carrier 3. When the pressure block 49 applies force downward and fits against the forming plate 33, the end of the wire is bent at 90°.

[0068] In this embodiment, by setting the side of the protruding part 73 of the shaping gripper 71 as an inclined surface and protecting the end of the wire on both sides by the claws 440 during pressure holding, not only the bending of the short-sized end of the wire harness 10 is effectively realized, but also the bending effect is ensured. In particular, it is suitable for the bending of the end of the wire harness 10 with multiple wire cores, and can effectively ensure the centering and gathering of multiple wire cores after bending, meeting the actual bending requirements.

[0069] As Figure 12 shown, it further includes a detection bracket 5 for supporting the detection component. The detection component is mounted above the translation module 1 by the detection bracket 5, which is convenient for detecting the wire harness 10 on the carrier 3 after bending.

[0070] In this embodiment, the detection component can adopt a line laser 51 and / or a camera component 52 to detect the bending of the wire harness 10 according to actual requirements.

[0071] In this embodiment, the conventional principles of the line laser 51 and the camera component 52 can be used to detect the bending of the wire harness head, such as image comparison, image analysis, etc., to judge and output whether the bending is qualified.

[0072] In this embodiment, the structure of the detection bracket 5 is as follows: it includes a vertical column 53, on which a first cross bar 54 and a second cross bar 55 are clamped and installed at intervals. A first longitudinal bar 56 is clamped and installed on the first cross bar 54, and a second longitudinal bar 57 is clamped and installed on the second cross bar 55. The first cross bar 54 and the first longitudinal bar 56, the second cross bar 55 and the second longitudinal bar 57 respectively form an L-shaped structure in the horizontal plane. The camera component 52 is supported and installed by the end of the first longitudinal bar 56, and the line laser 51 is supported and installed by the end of the second longitudinal bar 57.

[0073] In this embodiment, the position adjustment of the camera component 52 and the line laser 51 in space can be realized by adjusting the positions of the first cross bar 54 and the second cross bar 55 on the vertical column 53, adjusting the position of the first longitudinal bar 56 on the first cross bar 54, adjusting the position of the second longitudinal bar 57 on the second cross bar 55, as well as adjusting the position of the camera component 52 on the first longitudinal bar 56 and adjusting the position of the line laser 51 on the second longitudinal bar 57.

[0074] The usage method of the flexible wire harness bending automation equipment in this embodiment includes the following steps:

[0075] Step 1: Install the wire harness 10 on the carrier 3, and the head of the wire harness 10 protrudes outwards; specifically:

[0076] Position and place the wire harness 10 on the bottom plate 31 of the carrier 3, and combine the installation of the pressing plate 32 to realize the installation of the wire harness 10 on the carrier 3. The head of the wire harness 10 with bending passes through the through hole of the pressing plate 32 and protrudes outwards.

[0077] Step 2: The manipulator 8 drives the shaping component 7 to move to the head of the wire harness 10, and the shaping jaws 71 move towards each other to clamp the head at the bending part 72, and the manipulator 8 drives the head to be pre-bent away from the carrier 3; specifically:

[0078] The manipulator 8 drives the bending part 72 of the shaping jaws 71 to extend to the place where the wire harness 10 is to be bent. The clamping finger cylinder drives the shaping jaws 71 to move towards each other until the protruding parts 73 at the ends of the shaping jaws 71 are in contact, so that the head of the wire harness 10 passes through and is placed in the interval between the two shaping jaws 71. The manipulator 8 drives the shaping jaws 71 to move, and the head of the wire harness 10 is restricted by the protruding part 73 in contact with the end face 74 and is bent passively to realize pre-bending.

[0079] Step 3: The manipulator 8 drives the bending assembly 6 to move to the end of the wire harness 10. The bending jaws 61 clamp the pre-bent end, and the manipulator 8 drives the end to continue bending in the pre-bent direction.

[0080] Step 4: The wire harness 10 moves along the translation module 1 with the carrier 3 to the pressure-holding mechanism 4. The pressure-holding mechanism 4 applies pressure to the bent end of the wire harness 10 for a preset time. Specifically:

[0081] The linear drive power source 42 operates to drive the pressure block 49 and the upper jaw 440 of the pneumatic jaw 44 close to the carrier 3. The linear drive power source 43 operates to drive the pressure block 49 and the jaw 440 to move synchronously towards the wire harness 10 until the jaw 440 is located on both sides of the wire harness 10. The pneumatic jaw 44 works to make the jaws 440 approach each other and close to both sides of the wire harness 10. Then, the linear drive power source 45 operates to drive the pressure block 49 close to and contact the end until the pressure block 49 abuts against the forming plate 33 below the bent part of the end. As the linear drive power source 45 continues to operate, the elastic member 48 compresses. The pressure sensor 9 provides real-time feedback on the pressure. Based on the pressure and the holding time, the pressure block 49 realizes pressure-holding for the bent end.

[0082] Step 5: The translation module 1 drives the carrier 3 through the transfer seat 2, so that the bent end of the wire harness 10 enters the detection range of the detection component, and the detection component detects the bending.

[0083] The present invention realizes the bending of the short-sized end of the wire harness 10, especially suitable for the bending of the ends of wire harnesses 10 with multiple cores, and can effectively ensure the centering and gathering of multiple cores after bending, meeting the actual bending requirements.

[0084] The present invention realizes the automation of wire harness bending, greatly improves and ensures the bending efficiency and bending effect, and effectively reduces or even avoids damage to the end during the bending process.
