Description

Technical Field

[0001] The utility model relates to the technical field of wire harness equipment, and particularly relates to a jaw mechanism and a wire stacker. Background Art

[0002] In the production process of wire harnesses, a complete wire harness often needs to go through multiple processes such as wire cutting, wire stripping, and terminal riveting. With the rapid development of automotive industrialization and the increasing market demand, as an important component of automobiles, automotive wire harnesses directly affect the electrical performance of automobiles. In order to control the cost of wire harnesses and meet the growing demand, many manufacturers currently use industrial upgrading and adopt robotic arms or mechanical claws to improve the efficiency of wire harness material transfer.

[0003] However, in the actual production process, only one mechanical claw can be installed on a set of transmission devices or automatic control systems. During the process of wire harness feeding, it is necessary to wait for the mechanical claw to repeatedly move back and forth between two workstations to achieve the material transfer of the wire harness. In fact, the use efficiency of automation equipment has not been fully explored. Therefore, on the basis of the original design, the applicant proposes an improved solution. Summary of the Utility Model

[0040] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art 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 embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0041] Please refer to Figures 1-3 together. The present utility model discloses a jaw mechanism. The jaw mechanism 1 is installed at the left rear of the wire stacking machine 2 and includes a driving device a1, a main jaw a2 and a sub-jaw a4. Among them, the driving device a1 is composed of two transmission elements arranged in parallel up and down. The two transmission elements move independently and are driven by fluid or electricity. Among the two transmission elements, a first connecting block a3 is installed on one transmission element, and a second connecting block a5 is installed on the other transmission element. Moreover, the length of the first connecting block a3 is greater than that of the second connecting block a5. And since the main jaw a2 is arranged at the end of the first connecting block a3 and the sub-jaw a4 is installed at the end of the second connecting block a5, the main jaw a2 and the sub-jaw a4 can move without interfering with each other during displacement. During the actual operation of the equipment, the first connecting block a3 and the second connecting block a5 move horizontally under the drive of the two transmission elements, and thus drive the main jaw a2 and the sub-jaw a4 to move independently and freely.

[0042] In this embodiment, as Figure 2 and Figure 3 show, the transmission element is a rodless cylinder, and a closed-loop control method can be adopted for the main jaw a2 and the sub-jaw a4, that is, a linear encoder is installed on the rodless cylinder. The linear encoder detects the positions of the main jaw a2 and the sub-jaw a4, directly controls the relative positions of the main jaw a2 and the sub-jaw a4 through the PLC, and opens or closes the jaws after the main jaw a2 and the sub-jaw a4 reach the positions. On the other hand, optionally, the transmission element can also adopt the method of installing limit switches, that is, two limit switches are arranged at both ends of the transmission element. When the jaw triggers the limit switch, it automatically opens or closes and drives the jaw to return through the transmission element.

[0043] Based on the same inventive concept, as Figures 4-6The utility model also discloses a wire stacking machine, including the above-mentioned clamping mechanism, including a stand b1, a buffer b3 and a stacking tool b4, wherein a conveying device b2 is installed on the top of the stand b1, and the conveying device b2 is used to convey the wire harness and move the wire harness into the buffer b3 through the clamping mechanism. In this embodiment, a driving device a1 is installed at the end of the conveying device b2, and an operator b5 is arranged above the conveying device b2. The operator b5 is provided with an emergency stop switch and a display screen for displaying the working parameters of the equipment. The stacking tool b4 is located below the buffer b3, and the stacking tool b4 is fixedly installed on the stand b1, and is used to receive the wire harness released by the buffer b3, and the buffer b3 is installed below the conveying device b2, and the buffer b3 is connected to the stand b1 in a transmission manner and is suitable for flipping downwards so as to dump the wire harness into the stacking tool b4.

[0044] In some embodiments, Figure 5 and Figure 6 , the buffer b3 includes a dump bucket b31 and a support b32, the stand b1 is hinged to the top of the dump bucket b31, the bottom of the dump bucket b31 is hinged to the head of the support b32, and the tail of the support b32 is hinged to the stand b1. In this embodiment, Figure 4 The support device b32 has an automatic telescopic function and can support the swing of the tipping bucket b31. Specifically, the support device b32 is a cylinder or an electric lifting push rod, and its length can be electrically controlled.

[0045] In some embodiments, Figure 5 The tipping bucket b31 and the stacking tool b4 are mesh structures or hollow structures to reduce the weight of the tipping bucket b31 and the stacking tool b4 and reduce the energy consumption of the equipment.

[0046] In some embodiments, the transmission device b2 includes a motor b21 and a transmission bracket b23, wherein the motor b21 is suitable for driving the transmission belt b24 to operate and drive the wire harness to move, and a pulley b22 is fixedly sleeved on the shaft of the motor b21, and the pulley b22 is used to drive the transmission belt b24 to rotate, and the transmission belt b24 is sleeved on the transmission bracket b23, and the transmission belt b24 has anti-skid patterns, which can prevent it from slipping when conveying the wire harness. In this embodiment, the motor b21 can adjust the installation position of the motor b21 on the transmission bracket b23, and adapt to transmission belts b24 of different lengths, so that the length of the equipment can adapt to the length requirements of the cable, and use a single motor to drive the belt transmission, reducing the difficulty of equipment maintenance.

[0047] In some embodiments, Figure 6, a moving component is provided at the bottom of the vertical frame b1. The moving component includes a connecting frame b11 and lifting feet b13. The connecting frame b11 is provided at the bottom of the vertical frame b1. Universal wheels b12 are provided at both ends of the connecting frame b11, and the lifting feet b13 are arranged in pairs on the connecting frame b11. When the equipment needs to be parked, the lifting feet b13 can be lowered so that the universal wheels b12 are separated from the ground, thereby preventing the wire stacking machine from slipping.

[0048] 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.
