Description

Technical Field

[0001] The utility model relates to the technical field of wire stacking machine accessories, and particularly relates to an incoming wire induction device. Background Art

[0002] In wire harness production, a whole roll of wire harness needs to be cut into line segments according to requirements, and the cut line segments need to be gathered together by a wire stacking machine for production line workers to pick up, package and pack.

[0003] During the process of storing the wire harness, two points need to be particularly noted. First, after the cut line segments are transferred, the ends of the wire harness should be kept neat and consistent after falling into the wire stacking machine, and there should be no uneven situation. Second, during the transfer process, the wire harness should not interfere with the wire guiding mechanism, and the problem of wear on the surface of the wire harness should be avoided.

[0004] Currently, in existing equipment, since the wire harness always flows freely, there is always a certain delay between the sensor and the actuator, making it difficult for the equipment to meet the use requirements in terms of accuracy, so it is very difficult to solve the above two problems at the same time. Content of the Utility Model

[0005] Therefore, the utility model provides an incoming wire induction device to solve the problem of insufficient accuracy caused by the free movement of the cable in the prior art.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The utility model discloses an incoming wire induction device, which is installed on a wire stacking machine, and the wire harness enters the wire stacking machine through the incoming wire induction device. It is characterized in that it includes:

[0008] A wire guiding device, the bottom of which is arranged on a base, and an induction switch is installed above the wire guiding device;

[0009] A guide roller, which is rotatably arranged in the base, the end of the guide roller is coaxially driven and connected with a power machine and drives the guide roller to rotate, and the power machine is installed on the side of the base;

[0010] A wire pressing mechanism, a pressing wheel is installed at the bottom, the pressing wheel is aligned with the guide roller, and the wire pressing mechanism is adapted to drive the pressing wheel to move downwards to press the wire harness tightly;

[0011] Wherein, a feedback element is installed on the power machine, and the guide roller is in contact with the pressing wheel and drives the pressing wheel to rotate through friction.

[0012] Further, the feedback element is an encoder.

[0013] Further, the wire pressing mechanism includes a bracket and a telescopic driving element. The base is connected to the bottom of the bracket. A telescopic driving element is installed at the top of the bracket. The telescopic driving element is in transmission connection with the pressing wheel and drives the pressing wheel to move vertically.

[0014] Further, the telescopic driving element is a push-pull electromagnet or a cylinder.

[0015] Further, the wire guiding device includes:

[0016] A mounting seat, in which a conduit is horizontally inserted in the middle;

[0017] A connecting frame is screwed and fixed to the top of the mounting seat, and an induction switch is installed on the connecting frame;

[0018] When the induction switch fails to detect the cable, the power machine is controlled to stop rotating.

[0019] Further, the power machine is a stepping motor or a servo motor.

[0020] Further, rubber layers are provided on the surfaces of the guide roller and the pressing wheel.

[0021] The utility model has the following advantages:

[0022] The utility model discloses an incoming line induction device, which guides the wire harness through the wire guiding device and presses the wire harness by the pressing wheel and the guide roller to prevent the problem of wire deviation. Among them, an encoder for feedback angular displacement is installed on the power machine to sense the position. When the induction switch fails to detect the passing of the wire harness, the pressing wheel moves downwards. After pressing the wire, the power machine rotates, thereby driving the wire harness to continue to move forward until the end of the wire breaks away from the induction switch. At this time, the power machine stops rotating, so that the wire harness can stop at the specified position each time, thereby enabling the ends of the gathered wire harness to be aligned. Compared with the prior art, the utility model has the advantages of reliable performance and high precision, and solves the problems of wire harness surface wear and low precision caused by the delay of the actuator.

[0030] The following specific embodiments illustrate the implementation manners of the present utility model. Those familiar with this technology can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope protected by the present utility model.

[0031] Please refer to Figures 1-4 , the incoming wire induction device disclosed by the present utility model is installed on the wire stacking machine. The wire harness enters the wire stacking machine through the incoming wire induction device, and the wire harness is moved and gathered by the clamping jaws. Now, the technical solution is described by means of specific embodiments.

[0032] Such as Figure 1, in a specific embodiment disclosed by the present utility model, the main structure of the incoming line induction device includes a wire guiding device 1, a guide roller 3, and a wire pressing mechanism 5. Among them, the bottom of the wire guiding device 1 is arranged on a base 2. The wire harness enters from the head end of the wire guiding device 1, passes above the wire guiding device 1, and an inductive switch 6 installed thereon detects and generates a switching signal, and then is released from the tail end of the wire guiding device 1 and enters the position of the guide roller 3 along the base 2. The guide roller 3 is installed below the wire pressing mechanism 5, and the end of the guide roller 3 is coaxially driven and connected to a power machine 4, thereby driving the guide roller 3 to rotate.

[0033] In this embodiment, as Figure 2 and Figure 3 , the guide roller 3 is aligned with a pressing wheel 7, and the pressing wheel 7 is installed at the bottom of the wire pressing mechanism 5. When the inductive switch 6 fails to detect the passing of the wire harness, after releasing a switching signal, the wire pressing mechanism 5 first drives the pressing wheel 7 to move downward to tightly press the wire harness passing through the guide roller 3, and then the clamping jaws clamp the wire harness. After the pressing wheel 7 is lifted, the wire harness is moved. Among them, a feedback element 8 is installed on the power machine 4, and the angular displacement information of the power machine 4 can be transmitted in a timely manner by using the feedback element 8.

[0034] Specifically, when the inductive switch 6 fails to detect the passing of the wire harness, the feedback element 8 sends a signal to the PLC, and then the PLC is used to control the power machine 4 to stop rotating. In this embodiment, both the pressing wheel 7 and the guide roller 3 are made of rubber material, and their surfaces have a large friction coefficient and elasticity, which can avoid the wire cable from being damaged and also avoid the wire harness from slipping on the guide roller 3.

[0035] In this embodiment, as Figure 2 , the power machine 4 is a stepper or servo motor. When receiving an electrical signal, the power machine 4 is controlled to stop rotating. And because the pressing wheel 7 moves downward and frictionally drives the guide roller 3, the guide roller 3 rotates. After the power machine 4 stops rotating, the end portions of the gathered wire harness can be aligned by clamping and moving the wire harness with the clamping jaws.

[0036] In this embodiment, as Figure 4 , the wire pressing mechanism 5 includes a bracket 51 and a telescopic driving element 52. The base 2 is connected to the bottom of the bracket 51, and the telescopic driving element 52 is installed at the top of the bracket 51. Among them, the height of the bracket 51 is adjustable to be adapted to the telescopic driving element 52. And the telescopic driving element 52 is drivingly connected to the pressing wheel 7, thereby driving the pressing wheel 7 to move vertically.

[0037] In this embodiment, the wire guiding device 1 includes a mounting seat 11 and a connecting frame 12. A conduit 13 is horizontally inserted in the middle of the mounting seat 11, and the conduit 13 serves to guide the wire harness. The connecting frame 12 is screwed and fixed on the top of the mounting seat 11, and the inductive switch 6 is installed on the connecting frame 12. The inductive switch 6 uses the occlusion or reflection of the light beam by the detected object to connect the circuit through the synchronous circuit, thereby detecting the presence or absence of the object.

[0038] In this embodiment, the telescopic driving element 52 is a cylinder or a push-pull electromagnet, which can be controlled in a pneumatic or electric manner through a PLC (programmable logic controller).

[0039] Although the present utility model has been described in detail with general descriptions and specific embodiments above, based on the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection required by the present utility model.
