The wire feeding guide wheel is installed on the left side of the wire feeding structure 11, and a wire feeding straightening structure 12 is installed at the rear end of the wire feeding structure 11.

[0028] The terminal crimping structure 9 is used to crimp one end of the wire, and the wire twisting structure 14 is used to twist multiple wire cores together to solve the problem of wire branching. The clamp seat rotates under the drive of the stepper motor to start the sequential wire twisting action.

[0031] Working principle:

[0032] When this fully automatic single-press single-thread heat shrink tube twisting and tinning terminal machine is needed, the user can first assemble the overall structure as shown in the figure. After the assembly is completed, the overall structure is placed in the corresponding position, and then the specific equipment operation is started. The specific operation steps are as follows:

[0033] 1. The wires on the external wire-laying support are sent to the wire-feeding structure 11 through the wire-feeding and straightening structure 12, and then sent to the stripping structure 13 for stripping at one end;

[0034] 2. Stripping device: Cut and strip the wire from the wire feeding structure 11, and the stripped insulation surface enters the waste discharge pipe through the waste discharge hole and falls into the trash can. The upstream mobile positioning structure 10 sends the wire to the next station;

[0035] 3. Pipe threading device: The heat shrink tube at the rear end is sent to the front end, cut into a set length by the cutter in the pipe threading structure 8, and the pneumatic fingers in the pipe threading structure 8 are used to clamp the sleeve and pass it through one end of the wire and send it to the next station;

[0036] 4. Terminal crimping: The wire stripped of the insulation surface is crimped to the terminal by the terminal crimping structure 9, so as to complete the separation of the terminal strip and the terminal;

[0037] 5. Hot air gun: The wire with one end of the terminal crimped is baked by the hot air gun to shrink and tighten the heat shrink tube.

[0038] 6. The wire is moved to the stripping structure 13 through the upstream movable positioning structure and sent forward. The wire is cut by the cutting blade in the middle and the stripping of the rear end is completed. The whole wire is sent to the next station through the downstream movable positioning structure 5.

[0039] 7. Wire twisting device: remove the surface insulation layer of the other end of the wire, insert the exposed wire core into the wire twisting clamp seat, and the stepper motor drives the wire twisting clamp seat to rotate to complete the wire core twisting and send it to the next station;

[0040] 8. Flux device: insert the twisted wire into the flux container to dip into the flux liquid;

[0041] 9. Tinning device: The tinning fixture clamps the wire, and the stepper motor drives the fixture to rotate 90 degrees. The wire core is inserted into the tin melter for spot welding. After the spot welding is completed, the fixture returns to the origin and the wire is sent to the next station;

[0042] 10. Wire taking structure: adopt automatic speed control method to take in materials, and control the rotation angle of the conveyor belt to ensure that the finished wire harness falls accurately into the finished product slot.

[0043] Compared with the prior art, this case has the following advantages:

[0044] 1. Accurate positioning: The upstream mobile positioning structure and the downstream mobile positioning structure adopt a spiral transmission structure driven by a servo motor. The servo motor monitors the status of the motor in real time through feedback devices such as encoders, thereby achieving precise position, speed and other control. It can cope with applications with high loads and high inertia loads, has better stability and accuracy at high speeds, and can maintain stable speed and position during continuous operation;

[0045] 2. Fast speed and high production capacity: The whole process is automatic and intelligent production, no manual operation is required, the mechanical action is fast and convenient, the finished product quality is high, and the disadvantages of uneven quality caused by manual operation are improved;

[0046] 3. The length of the stripping and heat shrink tubing can be set. The stripping length at both ends of the wire and the length of the heat shrink tubing can be set to different sizes through parameters;

[0047] 4. Both long and short wires can be used;

[0048] 5. Use hot air gun 2 to replace the heating coil high temperature furnace structure, and the efficiency is increased by 38%;

[0049] 6. The strength of the twisted wire can be changed by modifying the parameters;

[0050] 7. The flux structure has changed from the previous cylindrical shape to a form of conveying the flux liquid downwards. It uses a motor to convey it upwards, making the structure more beautiful and simple.

[0051] The specific technical parameters are as follows:
