Description

Technical Field

[0001] The utility model relates to the technical field of waterproof plug-piercing machines, in particular to a feeding device for the plug-piercing machine. Background Art

[0002] As electronic wiring harnesses are increasingly used in the electronics, automotive and other industries, the requirements for them are also getting higher and higher. Especially in wiring harness production, due to the need to improve the durability and waterproof performance of the wiring harness, waterproof plugs are generally installed on both ends of the stripped wires.

[0003] At present, there are devices on the market that can automatically or semi-automatically install waterproof plugs. The main principle is to load the material through a linear vibrating guide rail, and use a motor to drive the pendulum needle structure to rotate 90 degrees to connect the waterproof plug to the end of the wire. This feeding structure will generate a lot of noise due to the large starting torque of the motor. At the same time, since the pendulum needle structure is relatively thin, it is easy to be deformed by force under continuous motor drive.

[0004] In view of this, the applicant proposes a new feeding mechanism, which can make the feeding structure more stable, reduce noise, and increase the service life of the equipment. Utility Model Content

[0005] To this end, the utility model provides a feeding device for a bolt threading machine to solve the problems in the prior art of shortening the life of the feeding mechanism and causing noise when the starting torque of the motor is large due to the use of a swing needle structure.

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

[0026] The utility model has the following advantages:

[0027] This utility model utilizes a secondary feed device to drive the swing arm mechanism, which forms a planar pair with the bent groove on the correction guide.

Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0038] Please refer to Figures 1-6 The present utility model discloses a feeding device for a bolt threading machine, which is installed on a waterproof bolt threading machine and comprises a main feed device 1, a correction guide 3, a swing arm mechanism 7, and a forming die 8. The bottom of the main feed device 1 is mounted on a base 6, while a secondary feed device 2 is slidably mounted on top of the main feed device 1, thereby driving the secondary feed device 2 in linear motion. The main feed device 1 is used to thread the waterproof bolt onto the wire, while the secondary feed device 2 is used to correct the position of the waterproof bolt so that it can be threaded horizontally onto the wiring harness.

[0039] Specifically, such as Figure 6 In this embodiment, a correction guide 3 is provided on the outside of the auxiliary feeding device 2, and a bending groove 5 is provided inside the correction guide 3. The relative position of the straight guide 3 and the auxiliary feeding device 2 remains fixed, and the purpose of correcting the waterproof plug is achieved through the plane pair between the bending groove 5 and the swing arm mechanism 7. In this embodiment, the top end of the swing arm mechanism 7 is hinged to one end of the connecting rod 4, and the other end of the connecting rod 4 is slidingly set in the bending groove 5. The bottom end of the swing arm mechanism 7 is hinged to the auxiliary feeding device 2, and the auxiliary feeding device 2 drives the swing arm mechanism 7 and the connecting rod 4 to move along the bending groove 5. On the other hand, a forming mold 8 is also provided in front of the swing arm mechanism 7. Specifically, the swing arm mechanism 7 can install the waterproof plug into the forming mold 8 and fix the waterproof plug to the wire harness through the forming mold 8.

[0040] In some embodiments, as Figure 2The base 6 includes a bottom frame 61, a vertical frame 62 and a cover shell 63, wherein the main feeding device 1 is installed on the bottom frame 61, the top of the bottom frame 61 is provided with a vertical frame 62, the front side of the vertical frame 62 is provided with a cover shell 63, and the rear side is provided with a cylinder feeding mechanism. During specific use, since the swing arm mechanism 7 is arranged below the cover shell 63, the compressed air flow generated by the cylinder feeding mechanism is used to introduce the waterproof plug from the cover shell 63 through the pipeline to the swing arm mechanism 7, and then the swing arm mechanism 7 corrects the position of the waterproof plug and puts it on the wiring harness. Among them, the cylinder feeding mechanism is a device that compresses air with a cylinder as a driving element. When the compression is released, the compressed air flow generated can flow along the pipeline, thereby pushing the waterproof plug forward.

[0041] In some embodiments, as Figure 6 The auxiliary feeding device 2 includes a rodless cylinder 21 and a slide 23, wherein a correction guide 3 is fixedly provided on the side of the cylinder body of the rodless cylinder 21, and the rodless cylinder 21 drives the slide 2 to move, and the slide 2 is slidingly provided on the guide rail 22 located at the top of the cylinder body, and a hinge seat 24 is provided on the slide 23, and a swing arm mechanism 7 is hingedly provided on the hinge seat 24. The swing arm mechanism 7 can only move within a right angle range on the hinge seat 24.

[0042] In some embodiments, as Figure 4 The molding die 8 includes a locking block 81 and a guide frame 83. The locking block 81 is used to insert the wiring harness, and a pressure block 82 is provided above the locking block 81. If the locking block 81 contains a wiring harness, a waterproof plug can be inserted. Specifically, the locking block 8 is fixedly mounted on the bottom of the guide frame 83, and a pressure block 82 is slidably provided on the upper end of the guide frame 83. The pressure block 82 is adapted to slide downward along the guide frame 83. A detection sensor 84 is provided on the side of the guide frame 83 to detect whether the waterproof plug in the locking block 81 has been inserted into the wiring harness.

[0043] In some embodiments, as Figure 6 The main feeding device 1 includes a linear mover 11, a limit switch 12 and a damper 13, wherein the linear mover 11 is a push-pull electromagnet, a linear motor or a hydraulic cylinder, which can be driven and controlled by electricity. The linear mover 11 can drag the auxiliary feeding device 2 to move forward in a straight line, and a limit switch 12 is provided on the outside of the auxiliary feeding device 2. In terms of specific application, since the damper 13 is installed on the base 6, the damper 13 can offset the limit switch 12, thereby protecting the limit switch 12. When the damper 13 triggers the limit switch 12, the linear mover 11 can be moved backward, thereby completing a fixed stroke through the linear mover 11 to achieve the installation of the waterproof plug.

[0044] In some embodiments, as Figure 3 and Figure 6The swing arm mechanism 7 includes an arm elbow 71 and a material support 73. The rear end of the arm elbow 71 is hinged to the hinge seat 24, while the material support 73 is fixed to the front end of the arm elbow 71. The material support 73 and the arm elbow 71 are perpendicular to each other. In addition, a level sensor 72 is provided on the material support 73. When the material support 73 is in a horizontal state, the main feeding device 1 is activated and drags the swing arm mechanism 7 forward to connect the waterproof plug to the wiring harness. When the level sensor 72 senses that the material support 73 is level, the linear mover 11 is activated to connect the waterproof plug to the wiring harness.

[0045] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.
