[0065] Based on the above technical solution, the present technical solution proposes a miniature desktop terminal stripping and crimping machine, which can realize the feeding of terminals, wire stripping, wire and terminal docking, and wire and terminal crimping operations, and can realize fully automated operation, and can also realize only the wire stripping operation alone. Of course, the present technical solution includes but is not limited to this, and can also perform a single wire and terminal docking operation, or perform riveting operations on the ends of materials similar to wires, etc. It can be flexibly set according to actual conditions, such as a miniature wire stripping machine used in this embodiment as an example;
[0066] By utilizing linear guide rails to achieve the mutual docking and coordination of various mechanisms, the sliding of various components along the corresponding linear guide rails is achieved by the power end 81 driving the coaxial crank multi-linkage mechanism 82. The wire stripping and terminal riveting require greater power. Therefore, a separate power crimping assembly 30 is provided to generate the corresponding power. The entire device can realize various operations of connecting the terminals and wires by supplying power to the power end 81 and the power crimping assembly 30. It has low energy consumption, and the coordination between the various components is smooth, so the production and processing efficiency of the terminals and wires can reach a higher level.
[0067] The push-pull linkage assembly 20, the one-way push terminal assembly 50, the wire stripping linkage assembly 60 and the wire clamping transmission mechanism 72 are driven by the coaxial crank multi-linkage mechanism 82, which can perform periodic cycle operations and periodically control the drive of the power crimping assembly 30, so that the power crimping assembly 30 and the coaxial crank multi-linkage mechanism 82 operate synchronously, so that a miniature desktop terminal stripping and crimping machine can also be integrated into the automation equipment as a mechanism, so that more comprehensive and fully automated operation can be achieved on other production lines of wires or terminals through the introduction of this technical solution.
[0068] In the operation of connecting the wires and terminals using the present technical solution, the associated terminals are first introduced along the terminal entrance 12 and connected to the terminal guide assembly 40, the device is started, and the sensor is used to identify the wire entrance 11 for example. When the wire is connected to the device along the wire entrance 11, the power end 81 drives the coaxial crank multi-linkage mechanism 82 to rotate. The power end 81 is preferably a power turbine worm motor that has sufficient power to operate. When the coaxial crank multi-linkage mechanism 82 rotates one cycle, the push-pull linkage assembly 20 is previously moved to a reasonable position against the wire, and then the stripping linkage assembly 60 and the wire clamping transmission mechanism 72 are operated. The stripping linkage assembly 60 moves to dock with the wire, and the wire clamping transmission mechanism 72 clamps the wire, and then the power crimping assembly 30 is operated. The wire stripping linkage assembly 60 is driven to grab the wire. After grabbing it, the push-pull linkage assembly 20 retreats. At this time, the wire stripping linkage assembly 60 and the power crimping assembly 30 will retreat synchronously, thereby stripping the wire end; after stripping, the wire stripping linkage assembly 60 retreats, and the power crimping assembly 30 resets. Synchronously, the single-wire pushing terminal assembly pushes the terminal to move to the rear of the wire, and then the push-pull linkage assembly 20 moves forward again to drive the terminal to enter the end of the wire. At this time, the power crimping assembly 30 runs again to rivet the terminal to the wire, completing the connection between the wire and the terminal. After the operation is completed, the power crimping assembly 30 resets.

By setting the thread clamping reset spring 714, the two movable blocks 711 can be kept in an open state. This design enables the coaxial crank multi-linkage mechanism 82 to drive the thread clamping head 71 to move by moving away from or abutting against one of the linkage entries or movable blocks 711, thereby improving the flexibility of the cooperation between the coaxial crank multi-linkage mechanism 82 and the thread clamping linkage assembly 70.
[0075] Since the wires need to be clamped during the entire operation of wire stripping and wire terminal riveting connection, the wire clamping linkage assembly 70 needs to keep clamping the wires during the entire process, and the coaxial crank multi-linkage mechanism 82 is a mechanism that is always active, which will have a certain impact on the firmness and stability of the wire clamping. In addition, since the wires need to be kept in a clamped state at the longer end, the design accuracy of the coaxial crank multi-linkage mechanism 82 will inevitably be improved. In this regard, the present embodiment is further preferred, and the wire clamping linkage assembly 70 also includes a wire clamping fixing plate 73, a self-locking structure 74 installed on the wire clamping fixing plate 73, and a wire clamp installed on the wire clamping fixing plate 73. The linear guide 75 and the clamping pushing component 76 movably connected to the clamping fixing plate 73; the clamping transmission mechanism 72 is arranged in the housing 10 through the clamping fixing plate 73, and the clamping pushing component 76 is provided with a clamping power interface 77. The coaxial crank multi-linkage mechanism 82 is powered by the clamping power interface 77. The clamping transmission mechanism 72 and the self-locking structure 74 are both connected to the coaxial crank multi-linkage mechanism 82 through the clamping pushing component 76; the self-locking structure 74 includes a self-locking push rod 741, a longitudinal linear guide 742, a self-locking member 743, a self-locking reset spring 744, a transverse linear guide 745, an unlocking member 746 and an unlocking reset spring 74 When the cam 73 is in the unlock state, the locking cam 738 is in the unlock state, and the locking cam 738 is in the unlock state, so that the cam 738 is locked and the locking cam 738 is locked. The self-locking member 743 is provided with a beveled opening 749 that docks with the unlocking member 746, and the unlocking member 746 is provided with an arc-shaped protrusion 748 that docks with the beveled opening 749. The unlocking member 746 pushes the self-locking member 743 to overcome the elastic force of the self-locking reset spring 744 through the cooperation of the arc-shaped protrusion 748 and the beveled opening 749, thereby driving the self-locking member 743 to disengage from the self-locking push rod 741. The unlocking reset spring 747 is provided on the wire clamping fixing plate 73, and the unlocking reset spring 747 pulls the unlocking member 746, so that the unlocking member 746 slides along the transverse linear guide rail 745 to disengage from the self-locking member 743 through the elastic force of the unlocking reset spring 747.
[0076] The working principle after adding the self-locking structure 74 is as follows:
[0077] like Figure 12When the lock 712 is unlocked, the lock 712 is unlocked, and the lock 712 is in the unlock state, and the lock 712 is unlocked.
[0078] like Figure 13 As shown, in the process of closing the two clamping blocks 712, the clamping pushing member 76 moves to the right under the guidance of the coaxial crank multi-linkage mechanism 82, and the clamping pushing member 76 drives the clamping transmission mechanism 72 to contract. Figure 13 When the two clamping blocks 712 are docked and clamp the wire, the locking position of the self-locking push rod 741 is just below the self-locking part 743. At this time, the rightward movement of the wire clamping pushing component 76 causes the unlocking part 746 to move to the right by the pulling force of the unlocking reset spring 747 to disengage from the self-locking part 743. The self-locking part 743 will be buckled downward into the self-locking push rod 741 by the elastic force of the self-locking reset spring 744 to lock the wire clamping transmission machine, thereby realizing the self-locking operation of the wire clamping, so that the wire can be firmly clamped during the entire process of wire stripping and riveting the terminal.
[0079] See also Figure 15 , the main power unit 80, preferably, the coaxial crank multi-linkage mechanism 82 includes an output main shaft 811 that is power-connected to the power end 81, and a terminal linkage cam 812, a wire stripping linkage cam 813, a push-pull linkage cam 814, and a wire clamping linkage cam 815 are provided on the power output main shaft 811.

[0082] The coaxial crank multi-linkage mechanism 82 adopts a linkage cam provided with a cam groove 820 and a linkage push rod with a roller cam bearing 821. During operation, the coaxial crank multi-linkage mechanism 82 is divided into four areas, namely 0°-90°, 90°-180°, 180°-270°, and 270°-360°. When the coaxial crank multi-linkage mechanism 82 is at 0°, the wire is extended into the device along the wire entrance 11 to resist the power crimping assembly 30. After the wire is connected, the coaxial crank multi-linkage mechanism 82 rotates from 0° to 90°. At this time, the wire clamping linkage assembly 70 tightens the wire, and the wire stripping linkage assembly 60 moves to dock with the wire. After docking, the power crimping assembly 30 is driven to drive the wire stripping linkage assembly 60 to perform a skin cutting operation on the wire; the coaxial crank multi-linkage mechanism 82 The dynamic mechanism 82 rotates from 90° to 180°, at which time the push-pull linkage assembly 20 retreats to strip the wire. After stripping is completed, the power crimping assembly 30 is driven to disengage the wire stripping linkage assembly 60; the coaxial crank multi-linkage mechanism 82 rotates from 180° to 270°, at which time the wire stripping linkage assembly 60 retreats, and at the same time, the one-way push terminal assembly 50 pushes the terminal to the back of the wire and between the clamping heads; the coaxial crank multi-linkage mechanism 82 rotates from 270° to 360°, at which time the push-pull linkage assembly 20 pushes forward, and the one-way push terminal assembly 50 retreats, and the wire clamping linkage assembly 70 releases the wire. After completing these three actions, the power crimping assembly 30 is driven to rivet the terminal, thereby riveting the terminal onto the wire to complete the riveted connection between the wire and the terminal.
