[0030] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0031] An embodiment of the present invention provides a wire harness loading and unloading structure, comprising an inner cylinder assembly, an outer cylinder assembly and a driving assembly; the inner cylinder assembly can rotate relative to the outer cylinder assembly, and the driving assembly drives the inner cylinder assembly to rotate. As the inner cylinder assembly rotates, the materials are stored one by one in the gap between the inner cylinder assembly and the outer cylinder, thereby realizing the unloading operation of the materials. When loading is required, the materials are pulled out from between the inner cylinder assembly and the outer cylinder assembly.

[0032] The following describes in detail the components of the wire harness loading and unloading structure provided by the embodiment of the present invention, as well as the positional relationship and connection relationship of the components, in conjunction with the accompanying drawings.

[0033] like Figures 1 to 7 As shown, in the embodiment of the present invention, the inner cylinder assembly 10 includes an inner cylinder body 11, and a plurality of harness grooves 12 for storing the material 40 are circumferentially arranged on the outer wall of the inner cylinder body 11, and the harness grooves 12 are axially arranged along the inner cylinder body 11; the material 40 after unloading will be placed in the harness grooves 12, wherein the width of the harness grooves 12 may be the same as the outer diameter of the material 40, or slightly larger than the outer diameter of the material 40, and the height of the harness grooves 12 is not limited. When the material 40 is placed in the harness grooves 12, the material 40 does not interfere with the outer cylinder assembly 20.

[0034] The outer cylinder assembly 20 includes an outer cylinder body 21, which is sleeved on the outside of the inner cylinder body 11, and the distance between the inner wall of the outer cylinder body 21 and the inner wall of the inner cylinder body 11 is smaller than the outer diameter of the material 40. The outer cylinder body 21 includes a material opening 22, which is axially arranged along the outer cylinder body 21; the processed material 40 falls into the gap between the inner cylinder body 11 and the outer cylinder body 21 through the material opening 22. As the inner cylinder body 11 rotates, the wiring harness groove 12 will rotate to a position opposite to the material opening 22. At this time, the material 40 that falls between the inner cylinder body 11 and the outer cylinder body 21 can fall into the wiring harness groove 12.

[0035] Among them, the driving component 30 is connected to the inner cylinder body 11 and is used to drive the inner cylinder body 11 to rotate around the axis. As the inner cylinder body 11 continues to rotate, the material 40 falling into the material port 22 will fall into multiple harness grooves 12 one by one, thereby completing the material borrowing operation.

[0036] Continue to refer Figures 1 to 7 As shown, in the embodiment of the present invention, a plurality of harness grooves 12 are evenly distributed on the outer wall of the inner cylinder body 11; during the unloading process, the material 40 is periodically placed into the material port 22, and the inner cylinder body rotates at a uniform speed, so that the unloading operation can be carried out in an orderly manner.

[0037] And the axial length of the inner cylinder body 11 is smaller than the length of the material 40, and when the material 40 is located in the harness groove 12, both ends of the material 40 are located outside the harness groove 12. During the loading operation, that is, loading the material 40 to the next operation step, the ends of the material 40 can be clamped by the clamping structure at the edges of the inner cylinder body 11 and the outer cylinder body 21, and the material 40 can be pulled out of the harness groove 12 or taken out again from the material port 22, thereby completing the subsequent loading operation.

[0038] In the embodiment of the present invention, the inner cylinder assembly 10 further includes a rolling device 13, which is arranged on the outer wall of the inner cylinder body 11; when the inner cylinder body 11 rotates, the rolling device 13 rotates synchronously with the inner cylinder body 11 and rolls on the inner wall of the outer cylinder body 21. The rolling device 13 plays an auxiliary rolling role, so that the inner cylinder body 11 and the outer cylinder body 21 rotate relative to each other more smoothly. For example, the rolling device 13 includes a ball convexly arranged on the surface of the inner cylinder body 11, and the end of the ball abuts against the inner wall of the outer cylinder body 21. When the inner cylinder body 11 rotates, the ball rolls along the inner wall of the outer cylinder body 21.

[0039] Continue to refer Figures 1 to 7 As shown, in the embodiment of the present invention, the driving assembly 30 includes a driving motor 31 and a connecting tube 32. The driving shaft of the driving motor 31 is connected to the connecting tube 32 and is used to drive the connecting tube 32 to rotate around its axis; the connecting tube 32 is inserted into the interior of the inner tube body 11 and is fixedly connected to the inner tube body 11.

[0040] For example, the driving motor 31 is a servo motor, and the outer wall of the connecting tube 32 is fixedly connected to the inner wall of the inner tube body 11 through a clamping assembly. For example, the connecting tube 32 is connected to the inner tube body 11 through a clamping assembly; the clamping assembly includes a clamping protrusion 33 and a clamping groove 14, and when the connecting tube 32 is connected to the inner tube body 11, the clamping protrusion 33 is clamped in the clamping groove 14; the clamping protrusion 33 is provided on the connecting tube 32, and the clamping groove 14 is provided on the inner tube body 11, or the clamping protrusion 33 is provided on the inner tube body 11, and the clamping groove 14 is provided on the connecting tube 32.

[0041] The connection between the clamping protrusion 33 and the clamping groove 14 is used to achieve a fixed connection between the connecting tube 32 and the inner tube body 11, thereby preventing the drive assembly 30 and the inner tube assembly 10 from rotating relative to each other. For example, the clamping protrusion 33 can be set as an elastic structure, which has a certain amount of expansion and contraction along the radial direction of the connecting tube 32. When the connecting tube 32 is connected to the inner tube body 11, the clamping protrusion 33 is first compressed by a certain amount. As the connecting tube 32 and the inner tube body 11 are connected in place, the clamping protrusion 33 is clamped into the clamping groove 14. At this time, the clamping protrusion 33 pops out to achieve full clamping with the clamping groove 14.

[0042] For example, the drive assembly 30 also includes a sensor, which monitors the number of rotations of the drive assembly through the sensor. For example, the sensor is an angle sensor, which is arranged on the output shaft of the drive motor 31; or, it is convenient to locate the connection position between the drive assembly 30 and the inner cylinder assembly 10 through the sensor. For example, the sensor may also include a distance sensor, which is arranged on the bracket 35.

[0043] In the embodiment of the present invention, the outer cylinder assembly 20 also includes an expansion groove 23, the cross-sectional shape of the expansion groove 23 is a "V" shape, the wide end of the expansion groove 23 is an inlet, the narrow end is an outlet, and the narrow end of the expansion groove 23 is connected to the material port 22; the material 40 is introduced into the material port 22 through the expansion groove 23.

[0044] The wide opening of the expansion slot 23 has a certain expansion area, which is convenient for inserting the material 40 . After the material 40 enters the expansion slot 23 through the wide opening, the material 40 is guided to the narrow opening and the material opening 22 .

[0045] Continue to refer Figures 1 to 7 As shown, in the embodiment of the present invention, the outer cylinder assembly 20 further includes a limiting device; the limiting device is used to limit the rotation of the outer cylinder body 21. When the harness loading and unloading structure is in operation, the inner cylinder assembly 10 rotates and the outer cylinder assembly 20 is fixed. In order to ensure this state, a limiting device can be provided on the outer cylinder assembly 20 to limit the rotation of the outer cylinder body 21.

[0046] For example, the limiting device includes a limiting buckle 24 and a first claw 34. The limiting buckle 24 is arranged on the outer wall of the outer cylinder body 21. The driving assembly 30 also includes a bracket 35. The first claw 34 is arranged on the bracket 35. When the connecting cylinder 32 is connected to the inner cylinder body 11, the first claw 34 is engaged with the limiting buckle 24.

[0047] In the driving assembly 30 , the connecting cylinder 32 is a moving part, and the bracket 35 supporting the connecting cylinder 32 is a static part. The first claw 34 is arranged on the bracket 35 and then engaged with the limiting buckle 24 , thereby limiting the rotation of the outer cylinder body 21 .

[0048] In the embodiment of the present invention, the limiting device also includes a telescopic spring (not shown in the figure) and a second claw 15. The telescopic spring is connected to the limiting buckle 24 and is used to drive the limiting buckle 24 to move along the set direction; the second claw 15 is connected to the edge of the inner cylinder body 11, that is, the second claw 15 is arranged on the side end of the inner cylinder body 11, on the non-circumferential surface, and the second claw 15 protrudes radially of the inner cylinder body 11 and is higher than the circumferential surface of the inner cylinder body 11.

[0049] When the connecting tube 32 is not connected to the inner tube body 11, the telescopic spring drives the limit buckle 24 to move axially to engage with the second claw 15. When the connecting tube 32 is connected to the inner tube body 11, the first claw 34 engages with the limit buckle 24 and overcomes the driving force of the telescopic spring to separate the second claw 15 from the limit buckle 24.

[0050] In the above structure, when the inner cylinder assembly 10 is not connected, the inner cylinder body 11 and the outer cylinder body 21 are also limited and no relative rotation occurs.

[0051] The present invention also provides a wire harness production system, including the above-mentioned wire harness loading and unloading structure. The wire harness production system includes wire harness processing equipment, transfer equipment (ie, wire harness loading and unloading structure), and subsequent loading equipment.

[0052] By using the wire harness loading and unloading structure as a connection structure for cost and loading, the operation of the material 40 can be smoothly completed, and the wire harness loading and unloading structure has the advantages of easy operation, simple structure and smaller occupied space.

[0053] The present invention provides a wire harness loading and unloading structure and a wire harness production system. When in use, the inner cylinder body 11 is located inside the outer cylinder body 21 and rotates, and the material 40 (wire harness) enters the gap between the inner cylinder body 11 and the outer cylinder body 21 through the material port 22. When a wire harness slot 12 rotates to align with the material port 22, the material 40 falls into the current wire harness slot 12, and the inner cylinder body 11 continues to rotate, continuously loading the material 40 into the wire harness slot 12, thereby completing the unloading operation of the material 40. On one side of the wire harness loading and unloading structure, a clamping structure, such as a manipulator, can be configured to clamp the end of the material 40 through the manipulator, and pull the material 40 out of the wire harness slot 12 or take it out again from the material port 22, thereby completing the subsequent loading operation. The technical solution of the present invention can realize the continuous unloading operation of the wire harness. The loading and unloading operation of the structure is more convenient, the structure is simple, the space occupied is smaller, and a larger number of materials 40 can be stored.
