Description

Technical Field

[0001] The present invention relates to the technical field of terminal punching equipment, and more specifically, to a mobile terminal punching mechanism. Background Art

[0002] A terminal punching mechanism is a mechanism that presses and rivets metal terminals at the end of a wire, and it can be applied to automated equipment such as a wire harness or connection line automated production line. The existing terminal punching mechanism generally includes a terminal feeding device, an upper punching knife, an upper punching knife lifting drive device, and a lower punching knife. The upper punching knife lifting drive device can drive the upper punching knife to move downward to cooperate with the lower punching knife to press and rivet the riveting feet of the terminal at the end of the wire. During operation, the terminal punching mechanism can continuously press and rivet a preset number of metal terminals on multiple respective wires.

[0003] However, the existing terminal punching mechanism has the following deficiencies: In addition to the terminal punching mechanism, an automated production line generally also has other assembly stations or mechanisms (such as inspection, shell insertion, wire pulling, cutting, etc.). At this time, it is necessary to clamp the wires with a wire clamping fixture and transfer them to the terminal punching station and other respective stations in sequence. When moving to the terminal punching mechanism, the wire clamping fixture needs to clamp multiple parallel wires and move them between the upper punching knife and the lower punching knife of the terminal punching. After punching one terminal, the wire clamping fixture will move to a position, and then another wire will be replaced to punch the next terminal until all the wires in this group are assembled with their respective terminals. Only then can the wire clamping fixture move to the next station for the next process. During the terminal punching process, the wire clamping fixture needs to move, which will affect the work of other stations. Therefore, other stations cannot work simultaneously with the terminal punching mechanism and must wait until the entire terminal punching process is completed before they can work, which will reduce the production efficiency.

Loosen the screws and rotate the adjustment screw 202 to conveniently adjust the front and rear positions of the terminal mold, which is easy to operate.

[0049] As a preferred embodiment, for example, the mobile end-punching mechanism can be used with Figure 13 and Figure 14 The clamp circulation line shown in the figure is used, and the mobile end-attaching mechanism can be installed on one side of the clamp circulation line. The clamp circulation line can include a frame 31, a circulation line motor 32, a transmission shaft 33, a diverter 34, a cam divider 35, a rotating wheel 36, an annular chain belt 37 and a clamp 38, the rotating wheel 36 is installed at both ends of the frame 31, the chain belt 37 is connected between two rotating wheels 36, the chain belt 37 is formed by a plurality of chain blocks being hinged end to end, the clamp 38 is installed on each chain block of the chain belt 37, the output shaft of the cam divider 35 is connected to one of the rotating wheels 36, the circulation line motor 32 is connected to the input shaft of the diverter 34 through the transmission shaft 33, the input shaft of the diverter 34 is connected to the input shaft of the cam divider 35, and the circulation line motor 32 can drive the rotating wheel 36 to rotate, thereby driving all the clamps 38 on the chain belt 37 to move in a cycle.

[0050] The working principle of the present invention is as follows:

[0051] When the clamp 38 of the clamp circulation line conveys a row of multiple parallel wires to the workstation of the mobile terminal mechanism, the upper pressing knife lifting drive device 9 will drive the upper pressing knife 7 for terminal pressing to move downward. At this time, one end of the wire is just located on the top of the elastic lower pressing block 18, and the wire splitting nozzle 191 positions the designated wire. The upper pressing knife 7 presses the end of the designated wire into the rivet feet of the terminal 101 while moving downward, and then cooperates with the lower pressing knife 11 to bend the rivet feet of the terminal and rivet them to the wire (see Figure 12 ), and cut off the terminal 101 and the strip body portion 100 of the terminal strip.

[0052] When the pressing knife 7 moves downward, the wire dividing device 19 and the terminal feeding and moving device 16 work simultaneously.

[0053] After a terminal is assembled with a wire, the transverse movement driving device of the terminal die can drive the entire terminal die installed on the transverse movement slider to move laterally, so that the upper and lower crimping knives of the terminal can sequentially perform the crimping operation on multiple subsequent wires one by one. During this crimping process, the clip 38 on the fixture loop line does not need to move.

[0054] In summary, the design of the present invention is reasonable. It can perform crimping while moving itself without the need for the wire clamping fixture to move. At this time, it is convenient for other workstations or other mechanisms on the automated production line to perform corresponding operations during the temporary pause of the wire clamping fixture, greatly improving the production speed and production efficiency.

[0055] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
