Description

Technical Field

[0001] This application relates to the field of manufacturing, and in particular to a feeding fixture and equipment for wire harness workpieces. Background Technology

[0002] In the process of improving automation, we often encounter workpieces with wire harnesses (such as automotive linear displacement sensors). When it is necessary to automatically load or transfer workpieces with wire harnesses, there is usually no good solution for the wire harnesses of the workpieces, and manual handling can only be used, which makes it impossible to improve production efficiency.

[0003] In the existing technology, when a workpiece with a wire harness is received, the wire harness cannot be accurately positioned and placed. The wire harness floats freely within a certain range, resulting in the terminal position of the workpiece being unstable, and the fixture cannot accurately grasp and transport it. Utility Model Content

[0004] This application provides a loading fixture and equipment for wire harness workpieces, which solves the problem of gripping and transferring workpieces with wire harnesses.

[0005] In a first aspect, this application provides a loading fixture for a wire harness workpiece. The wire harness workpiece includes a body end, a terminal, and a wire harness. The loading fixture includes a mounting platform, a first clamp, a second clamp, a first linear drive mechanism, and a wire straightening component. The first clamp is disposed on the mounting platform and is used to clamp the body end. The second clamp is disposed on the mounting platform and is used to clamp the terminal. The first linear drive mechanism is disposed on the mounting platform and is used to drive the wire straightening component to move in a predetermined direction. The wire straightening component is connected to the first linear drive mechanism and can slide relative to the wire harness of the wire harness workpiece in a predetermined direction, thereby causing the terminal to move to the clamping point of the second clamp.

[0006] Secondly, this application provides a feeding device for wire harness workpieces, including a robot and a feeding fixture, wherein the robot is connected to the mounting platform of the feeding fixture.

[0007] The feeding fixture and equipment of this application have at least the following beneficial effects:

[0008] The loading fixture of this application is equipped with two clamps. When it is necessary to transfer a workpiece with a wire harness, the first clamp first clamps the body end of the workpiece. Then, the first linear drive mechanism drives the wire straightening component to slide in contact with the wire harness in a predetermined direction. The wire harness is straightened by the push of the wire straightening component, and the terminal at the end of the wire harness is pushed to the clamping point of the second clamp, so that the second clamp can clamp the terminal. The loading fixture of this application can adapt to the clamping and handling of workpieces with wire harnesses without precise positioning, and realizes the automation of assembly and transfer of such workpieces.

[0025] This embodiment discloses a feeding fixture and equipment for wire harness workpieces, such as... Figure 1 As shown, in this embodiment, the wire harness workpiece 1000 refers to a workpiece with a wire harness 1030 (e.g., a linear displacement sensor). The wire harness workpiece 1000 specifically includes a body end 1010, a terminal 1020, and a wire harness 1030. The two ends of the wire harness 1030 are connected to the body end 1010 and the terminal 1020, respectively. First, the loading fixture 2000 of this embodiment will be introduced.

[0026] like Figure 2 As shown, the loading fixture 2000 in this embodiment includes a mounting platform 100, a first fixture 200, a second fixture 300, a first linear drive mechanism 400, and a wire straightening component 500, as detailed below:

[0027] Mounting platform 100 is the main structure of loading fixture 2000, providing mounting and connection positions for various components.

[0028] like Figure 3 As shown, the first clamp 200 is disposed on the mounting platform 100. The first clamp 200 is used to clamp the body end 1010 of the wire harness workpiece 1000. In some preferred embodiments, the first clamp 200 is configured as a first pneumatic gripper, which is disposed at the lower end of the mounting platform 100. In addition, the first clamp 200 can also be configured as a biomimetic flexible gripper, etc.

[0029] like Figure 4 As shown, the second clamp 300 is disposed on the mounting platform 100 and is used to clamp the terminal 1020 of the wire harness workpiece 1000. In some preferred embodiments, the second clamp 300 is configured as a second pneumatic gripper; otherwise, the second clamp 300 may also be configured as a biomimetic flexible gripper, etc.

[0030] like Figure 4 As shown, in this embodiment, the second clamp 300 is mounted on the mounting platform 100 via the second linear drive mechanism 600. The second linear drive mechanism 600 can drive the second clamp 300 to move closer to and away from the wire harness workpiece 1000. Specifically, the second linear drive mechanism 600 is connected to the second clamp 300, and the second clamp 300 is moved by the second linear drive mechanism 600. In some preferred embodiments, the second linear drive mechanism 600 includes a second telescopic member 610 (e.g., a telescopic cylinder) and a lifting platform 620. The second telescopic member 610 is mounted on the mounting platform 100, and its telescopic end is connected to the lifting platform 620. The telescopic direction of the second telescopic member 610 is configured as the height direction, thereby driving the lifting platform 620 to move in the height direction. A second clamp 300 is mounted on the lifting platform 620. The lifting movement of the lifting platform 620 drives the second clamp 300 to move downwards to its clamping point A. Here, clamping point A refers to the clamping position of the second clamp 300, i.e., the position where the terminal 1020 is clamped. Figure 7 As shown by the dashed line A at the midpoint.

[0031] like Figure 4 As shown, in some preferred embodiments, there are two second clamps 300, which are spaced apart on the lifting platform 620 along a predetermined direction, namely... Figure 6 The horizontal direction is as follows. By providing second clamps 300 on both the left and right sides, the working condition of the workpiece terminal 1020 being on the left or right side can be adapted, thereby improving the flexibility of the loading clamp 2000.

[0032] like Figure 5 and Figure 6As shown, a first linear drive mechanism 400 is mounted on a mounting platform 100. The first linear drive mechanism 400 drives the wire straightening member 500 to move in a predetermined direction, thereby pushing the terminal 1020 at the end of the wire harness 1030 to the clamping point A of the second clamp 300. In some preferred embodiments, the first linear drive mechanism 400 includes a first telescopic member 410 and a connecting plate 420. The first telescopic member 410 is mounted on the mounting platform 100, and its telescopic direction is configured as the predetermined direction. The connecting plate 420 is L-shaped and connected to the telescopic end of the first telescopic member 410. The first telescopic member 410 can drive the connecting plate 420 to reciprocate in the predetermined direction. In this embodiment, the first telescopic member 410 is configured as a telescopic cylinder.

[0033] like Figure 6 As shown, the wire straightening component 500 is connected to the first linear drive mechanism 400. Under the drive of the first linear drive mechanism 400, the wire straightening component 500 can reciprocate in a predetermined direction. The wire straightening component 500 can slide into contact with the wire harness 1030 of the workpiece along the predetermined direction and push the wire harness 1030 to bend at a certain angle, causing the terminal 1020 connected to the end of the wire harness 1030 to swing to the clamping point A of the second clamp 300. Figure 7 As shown, Figure 7 The dashed line indicates the position of the terminal before the winding component moves, and the solid line indicates the position of the terminal after the winding component moves into place.

[0034] like Figure 6 As shown, in some preferred embodiments, there are two wire straightening components 500, and two second clamps 300 are spaced apart along the predetermined direction on the underside of the connecting plate 420. The two second clamps 300 can accommodate situations where the terminal 1020 is on the left or right side.

[0035] like Figure 8As shown, in this embodiment, the upper end of the wire straightening component 500 is connected to the connecting plate 420, and the lower end of the wire straightening component 500 is provided with an arc-shaped groove 510 and a guide slope 520. The inner arc surface of the arc-shaped groove 510 can cover at least part of the outer circumference of the wire harness 1030. In this embodiment, the inner radius of the arc-shaped groove 510 is slightly larger than the radius of the wire harness 1030 (for example, the inner radius of the arc-shaped groove is 1.1 to 1.5 times the radius of the wire harness). When the wire straightening component 500 slides in a predetermined direction, the inner arc surface of the arc groove 510 can slide in contact with the outer peripheral surface of the wire harness 1030. The arc groove 510 can restrict the position of the wire harness 1030 when the wire straightening component 500 moves, so that the wire harness 1030 can only bend at a certain angle with the linear movement of the wire straightening component 500 and cannot move up and down. The guide slope 520 is located outside the entrance of the arc groove 510 and is in contact with the inner arc surface of the arc groove 510. The guide slope 520 can guide the wire harness 1030 into the arc groove 510.

[0036] It should be noted that, in addition to the structure type described in this embodiment, the first linear drive mechanism 400 and the second linear drive mechanism 600 may also adopt other existing structures, such as linear modules.

[0037] like Figure 9 As shown, this embodiment also provides a wire harness workpiece loading device 3000. The loading device 3000 includes a robot arm 3010 and a loading fixture 2000. The robot arm 3010 is connected to the mounting platform 100 of the loading fixture 2000. The robot arm 3010 is used to drive the loading fixture 2000 to move to the target position.

[0038] One working method of the feeding device in this embodiment is as follows:

[0039] 1. The robotic arm 3010 moves the loading fixture 2000 to above the wire harness workpiece 1000;

[0040] 2. The robot arm 3010 drives the mounting table 100 to move downward, so that the body end 1010 of the wire harness workpiece 1000 is located within the clamping range of the first clamp 200, and then the first clamp 200 clamps the body end 1010 of the wire harness workpiece 1000.

[0041] Third, the first linear drive mechanism 400 drives the wire straightening component 500 to move linearly in a predetermined direction. The inner side of the wire straightening component 500 slides in contact with the wire harness 1030 of the wire harness workpiece 1000. During the linear motion, the wire straightening component 500 pushes the wire harness 1030 to bend at a certain angle (e.g., ...). Figure 7 As shown), the terminal 1020 connected to the end of the wire harness 1030 is then pushed to the clamping point A below the second clamp 300;

[0042] Fourth, the second linear drive mechanism 600 drives the second clamp 300 to move downward to the clamping point A. The second clamp 300 then clamps the terminal 1020 of the wire harness workpiece 1000. At this time, the body end 1010 and the terminal 1020 of the wire harness 1030 are clamped by the first clamp 200 and the second clamp 300 respectively, and the clamping work of the wire harness workpiece 1000 is completed.

[0043] Fifth, the robot arm 3010 then moves the loading fixture 2000 and the clamped wire harness workpiece 1000 to the target position. After that, the loading fixture 2000 releases the wire harness workpiece 1000, and the transfer of the wire harness workpiece 1000 is completed.

[0044] The above description is merely a specific implementation of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
