Description

Technical Field

[0001] The present application relates to the technical field of wire harness processing equipment, and in particular to an aluminum foil shaking and separating device. Background Art

[0002] The wire harness is usually composed of an outer sheath, an aluminum foil insulation layer and a wire core. When the end of the wire harness is crimped or other processes are performed, the outer sheath and aluminum foil layer need to be peeled off one by one.

[0003] Usually, the aluminum foil layer is peeled off by cutting the aluminum foil layer with a blade and then peeling the aluminum foil layer.

[0004] Although the stripping of the aluminum foil layer is achieved in the related art, the blade is likely to damage the insulation layer of the wire core inside the aluminum foil layer during the actual production process, thus affecting the quality of the wire harness production. Summary of the invention

[0005] In order to improve the quality of wire harness processing, the present application provides an aluminum foil shaking and separating device.

[0006] The present application provides an aluminum foil shaking separation device that adopts the following technical solution:

[0007] A shaking and separating device for aluminum foil comprises a wire support and clamping assembly and a shaking actuator, wherein the portion of the material from which the aluminum foil is to be peeled off is defined as a peeling portion, the wire support and clamping assembly and the shaking actuator are respectively located at two ends of the peeling portion, the wire support and clamping assembly is used to fix the material, and the shaking actuator is used to drive one end of the peeling portion to move in a direction perpendicular to the length of the material.

[0008] By adopting the above technical solution, when peeling off the aluminum foil layer, the material (i.e., the wire harness) is clamped and fixed by the wire support and clamp assembly. Then, the shaking actuator clamps one end of the stripping portion of the wire harness and drives one end of the stripping portion to move. The movement of the stripping portion causes the material to bend, and then the aluminum foil is torn at the position corresponding to the bending of the material, so that the aluminum foil on the stripping portion is disconnected from the aluminum foil at other positions of the material, thereby achieving separation of the aluminum foil. The aluminum foil can then be removed through the next process. The aluminum foil is separated by shaking the end of the material, thereby avoiding the situation in which the blade scratches the insulation layer of the wire core in the related technology, thereby improving the quality of wire harness production.

[0009] Optionally, the shaking actuator includes a support frame and a holding piece, and the holding piece is connected to the support frame and rotates in a direction perpendicular to the length direction of the material to clamp the material.

[0010] By adopting the above technical solution, after the holding piece clamps the material, it drives the end of the material to move through its own rotation, thereby achieving shaking of the end of the material.

[0011] Optionally, the shaking actuator includes a first rotating block, the first rotating block is rotatably connected to a support frame, and the holding member is mounted on the first rotating block.

[0012] By adopting the above technical solution, the rotation of the first rotating block can drive the holding member to rotate, thereby realizing the rotational connection between the holding member and the supporting frame.

[0013] Optionally, the shaking actuator also includes a second rotating block, which is located between the pinching piece and the first rotating block, the second rotating block is rotatably connected to the first rotating block, the pinching piece is fixed on the second rotating block, and the rotation axes of the first rotating block and the second rotating block are perpendicular.

[0014] By adopting the above technical solution, the first rotating block and the second rotating block rotate to drive the holding member to rotate, thereby realizing the rotation of the holding member in two different directions, thereby being able to drive the end of the material to bend in different directions, thereby facilitating the all-round tearing of the aluminum foil.

[0015] Optionally, the shaking actuator also includes a driving assembly for driving the first rotating block and the second rotating block to rotate, the driving assembly includes a mounting disk and a connecting rod, the mounting disk is rotatably connected to the support frame, the connecting rod is located between the second rotating block and the mounting disk, one end of the connecting rod is connected to the second rotating block, and the other end is connected to the mounting disk, the connecting rod can rotate arbitrarily relative to the mounting disk, and the rotation center of the connecting rod is spaced apart from the axis of the mounting disk.

[0016] By adopting the above technical solution, the mounting plate rotates, driving the movable end to move along the annular path, and then driving the holding piece installed on the second rotating block to move along the annular path, thereby achieving shaking of the peeling part.

[0017] Optionally, an eccentric adjustment block is arranged between the driving member and the connecting rod, and the eccentric adjustment block is slidably connected to the output shaft of the servo motor in a direction perpendicular to the output shaft of the servo motor. The end of the connecting rod facing away from the second rotating block is connected to the eccentric adjustment block. Sliding the eccentric adjustment block can adjust the distance between the end of the connecting rod and the rotation axis of the mounting disk.

[0018] By adopting the above technical solution, the sliding eccentric adjustment block adjusts the distance between the end of the connecting rod and the axis of the mounting disk, thereby changing the radius of the annular path of the movement of the end of the connecting rod, thereby adjusting the swing amplitude during the shaking process of the stripping part.

[0019] Optionally, a locking screw is provided on the mounting plate, and the locking screw is threadedly connected to the mounting plate. Rotating the locking screw can cause the locking screw to press against the eccentric adjustment block.

[0020] By adopting the above technical solution, the eccentric adjustment block is tightened by the locking screw, so that the sliding of the eccentric adjustment block can be limited, thereby improving the stability of the eccentric adjustment block during the shaking of materials.

[0021] Optionally, a displacement assembly is also included, which includes a sliding plate and a fixed plate. The sliding plate is slidably connected to the fixed plate, and the shaking actuator and the wire clamp assembly are both installed on the sliding plate.

[0022] By adopting the above technical solution, in the actual production process, the material is transported horizontally by the conveying equipment. Before the material is delivered, the sliding plate can be used to shake the actuator and the wire clamp assembly away from the material's conveying trajectory to reduce the impact on material transportation.

[0023] Optionally, the mounting plate can move in a direction perpendicular to its own rotation axis.

[0024] By adopting the above technical solution, the connecting rod can be driven to rotate by sliding the mounting plate, thereby driving the gripping member to move, thereby adjusting the direction of the gripping member's jaws. In the actual production process, the jaws can be oriented parallel to the length direction of the material by moving the mounting plate, which is convenient for gripping the material.

[0025] The present application has at least one of the following beneficial technical effects:

[0026] 1. The aluminum foil shaking separation device replaces single puncture with shaking, which reduces the damage to the core wire skin caused by the aluminum foil removal process. The wire can be rotated at any angle under the drive of the motor, and high precision is used to ensure that the position of the wire does not shift when it is handed over, thereby improving the production quality of the wire harness.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-5 This application is described in further detail.

[0035] The embodiment of the present application discloses an aluminum foil shaking and separating device.

[0036] Reference Figure 1 and Figure 2 , an aluminum foil shaking and separating device, comprises a wire support and clamping assembly 1 and a shaking actuator 2, wherein the wire support and clamping assembly 1 is used to clamp and fix the material (in this embodiment, it refers to the wire harness to be stripped of the aluminum foil layer). Here, the wire support and clamping assembly 1 is clamped at the tail of the stripping part (the aluminum foil to be stripped from the wire harness has a certain length, and the end of the stripping part away from the end of the wire harness is defined as the tail of the stripping part). The shaking actuator 2 is arranged on one side of the clamping assembly, and is used to clamp the head of the stripping part of the material (in this embodiment, the head of the stripping part is the end of the stripping part corresponding to the end of the wire harness). The shaking actuator 2 can drive the head of the stripping part to move. During the movement of the head of the stripping part, the wire harness is bent, and then the aluminum foil layer is broken. After the aluminum foil layer is broken, the next process can be entered to remove the broken aluminum foil layer to achieve the stripping of the aluminum foil layer.

[0037] Reference Figure 1 and Figure 2 The wire support and clamping assembly 1 includes a mounting frame 13 and a clamping member 11 mounted on the mounting frame 13. The clamping member 11 is a pneumatic clamping jaw, which clamps and fixes the material through the pneumatic clamping jaw to achieve support for the material.

[0038] Reference Figure 1 and Figure 2In the actual production process, the material moves horizontally from one side of the shaking and separation device to the direction close to the shaking and separation device, and the direction of material transportation is defined as the transportation direction. The clamping member 11 can move in a direction perpendicular to the transportation direction. The wire support and clamping assembly 1 also includes a lifting member 12 for driving the clamping member 11 to move. In this embodiment, the lifting member 12 is a cylinder, and the cylinder body of the cylinder is fixed on the mounting frame 13. The piston rod of the cylinder is fixedly connected to the clamping member 11, and the extension and contraction of the piston rod of the cylinder can drive the clamping member 11 to move. In the actual production process, before the material reaches the position where the shaking and separation device is located, the clamping member 11 can be driven by the lifting member 12 to move to one side of the material movement path to reduce the interference between the material and the clamping member 11.

[0039] Reference Figure 1 and Figure 3 The shaking actuator 2 includes a support frame 21, a first rotating block 22, a second rotating block 23 and a holding piece 24. The holding piece 24 is used to clamp the head of the stripping portion of the material. In this embodiment, the holding piece 24 is a four-claw clamp of model (MHS4-16D) produced by China Resources Pneumatic. The first rotating block 22 is rotatably connected to the support frame 21, and the second rotating block 23 is rotatably connected to the first rotating block 22. The rotation axis of the first rotating block 22 is vertically arranged and perpendicular to the rotation axis of the second rotating block 23. The holding piece 24 is fixedly connected to the second rotating block 23 by screws. The rotation of the first rotating block 22 and the second rotating block 23 can drive the holding piece 24 to rotate in different directions, thereby driving the head of the stripping portion to swing in multiple directions, thereby realizing the tearing and stripping of the aluminum foil layer.

[0040] Reference Figure 1 and Figure 3 The shaking actuator 2 also includes a driving assembly 3 for driving the first rotating block 22 and the second rotating block 23 to rotate. The driving assembly 3 includes a driving member 31, a mounting disk 32 and a connecting rod 33. The mounting disk 32 is a disc-shaped structure. The mounting disk 32 is rotatably connected to the support frame 21, and the rotation axis of the mounting disk 32 is parallel to the length direction of the material. The driving member 31 is arranged on the side of the first rotating block 22 away from the holding member 24, and is used to drive the mounting disk 32 to rotate. In this embodiment, the driving member 31 is a servo motor. The mounting disk 32 is coaxially fixed to the output shaft of the servo motor through a coupling. The two ends of the connecting rod 33 are defined as a fixed end and a movable end, respectively. The fixed end is fixed to the second rotating block 23, and the movable end is connected to the mounting disk 32 and is spaced apart from the rotation axis of the mounting disk 32. The rotation of the output shaft of the servo motor can drive the mounting plate 32 to rotate, and then drive the movable end to move along a circular trajectory, which can drive the first rotating block 22 and the second rotating block 23 to rotate, and then the holding piece 24 drives the stripping part head to move along a circular path, thereby realizing the reciprocating shaking of the stripping part head in the vertical and horizontal directions.

[0041] Reference Figure 3 and Figure 4 The shaking actuator 2 also includes an eccentric adjustment block 25, which is connected to the mounting disk 32 by sliding along the radial direction of the mounting disk 32, and the movable end is connected to the eccentric adjustment block 25 through a spherical bearing. The spherical bearing itself has a certain amount of free adjustment, so that the connecting rod 33 can be close to or away from the eccentric adjustment block 25 to a certain extent (it can also be understood as making the connecting rod 33 have a certain amount of expansion and contraction in the direction parallel to its own length. Of course, in some embodiments, the connecting rod 33 can also be directly set as a telescopic rod) to adapt to the movement of the eccentric adjustment block 25. The eccentric adjustment block 25 moves, thereby changing the distance between the movable end and the axis of the output shaft of the driving member 31, so that the amplitude of the swing of the clamping member 11 driven by the first rotating block 22 and the second rotating block 23 can be adjusted, so that the swing amplitude can be adjusted according to the actual production situation, and the aluminum foil can be peeled off. It should be noted that: in the actual production process, the radius of the circular path (which can also be understood as the swing amplitude) of the peeling end driven by the pinching piece 24 is relatively small, generally 2-5 mm, so the free adjustment amount brought by the eccentric bearing itself is sufficient to adapt to the movement of the eccentric adjustment block 25.

[0042] Reference Figure 3 and Figure 4 A threaded hole is provided on the mounting plate 32, and a waist-shaped hole 51 whose length direction is parallel to the sliding direction of the eccentric adjustment block 25 is provided at a position corresponding to the threaded hole. A locking screw 5 is provided on the mounting plate 32, and the locking screw 5 passes through the waist-shaped hole 51 and is threadedly connected in the threaded hole. Rotating the locking screw 5 can make the locking screw head press against the eccentric adjustment block 25 to limit the sliding of the eccentric adjustment block 25.

[0043] Reference Figure 3 and Figure 4 , the driving member 31 is slidably connected to the support frame 21 in a direction parallel to the output shaft of the servo motor. In this embodiment, the movement of the driving member 31 is directly driven by the cylinder. The servo motor rotates to make the connecting rod 33 parallel to the ground. At this time, the sliding driving member 31 drives the first rotating block 22 to rotate, thereby adjusting the direction of the clamping claws of the holding member 24 to make it parallel to the length direction of the material, so that the material can be inserted between the clamping claws of the holding member 24.

[0044] Reference Figure 3 and Figure 4The cylinder has two states during operation, namely, the state where the piston rod is located inside the cylinder and the state where the piston rod is located outside the cylinder. During the production process, the servo motor drives the gripping member 24 to move. After the peeling part is shaken, the servo motor output shaft stops moving. At this time, the connecting rod 33 is parallel to the ground. The movement of the cylinder piston rod is used to quickly adjust the angle of the connecting rod 33 in the direction parallel to the servo motor output shaft (it should be understood that the change in the angle of the connecting rod 33 brought about by this process is also adapted by the free adjustment amount of the spherical bearing itself), so that the gripping member 24 can clamp the material.

[0045] Reference Figure 1 and Figure 5 A displacement assembly 4 is provided below the shaking actuator 2 and the wire clamp assembly 1. The displacement assembly 4 is used to drive the shaking actuator 2 and the wire clamp assembly 1 to move in a direction parallel to the output shaft of the servo motor, so that the shaking actuator 2 and the wire clamp assembly 1 can be moved closer to or away from the material as a whole. At the same time, when the gripping member 24 of the shaking actuator 2 is in a clamping state, the length direction of its clamping jaws is parallel to the output shaft of the servo motor and to the length of the material. Moving the shaking actuator 2 in this direction can insert the material between multiple clamping jaws, which is convenient for clamping the material.

[0046] Reference Figure 1 and Figure 5 The displacement assembly 4 includes a sliding plate 41 and a fixed plate 42. The fixed plate 42 is fixedly connected to other process equipment or the ground, and the sliding plate 41 is slidably connected to the fixed plate 42. The support frame 21 and the mounting frame 13 are fixed to the sliding plate 41 by screws. The displacement assembly 4 also includes a driving screw 43, which is threadedly connected to the sliding plate 41. Rotating the driving screw 43 can drive the sliding plate 41 to slide, thereby adjusting the position of the sliding plate 41. In this embodiment, the driving screw 43 is directly driven by a servo motor.

[0047] The implementation principle of the aluminum foil shaking separation device in the embodiment of the present application is: the head of the stripping part of the material is driven to swing by the shaking actuator 2, so that the corresponding aluminum foil layer on the head of the stripping part is torn to realize the stripping of the aluminum foil layer. This avoids the situation in which the blade in the traditional technology causes damage to the insulation layer of the wire core, and improves the quality of wire harness production.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
