[0026] Working principle:

[0027] When this double-pressure double-through sheath 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:

[0028] 1. The wires on the external wire-laying support are sent to the wire-feeding structure 13 through the wire-feeding straightening structure 14, and then sent to the front stripping structure 15 for stripping at one end;

[0029] 2. Front stripping device: cuts and strips the wire from the wire feeding structure 13, 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 12 sends the wire to the next station;

[0030] 3. Sheathing device: The vibrating plate at the rear end sends the sheath to the front end through the conveying pipe, passes through the first sheathing structure 9, and uses the pneumatic fingers in the first sheathing structure 9 to clamp the sheath and pass it through one end of the wire to send it to the next station;

[0031] 4. Terminal crimping: The wire stripped of the insulation surface is crimped to the terminal by the first terminal crimping structure 11, so as to complete the separation of the terminal strip and the terminal;

[0032] 5. The wire is moved to the front stripping structure 15 through the upstream moving positioning structure and sent forward. The wire is cut by the cutting blade in the middle and the rear end stripping is completed. The whole wire is sent to the next station through the downstream moving positioning structure 5.

[0033] 6. Repeat steps 3 and 4 at the other end of the wire;

[0034] 7. Positioning and clamping: The upper and lower positioning clips 3 are pushed toward the middle to clamp the sheath, fix it in the set position and send it to the next station;

[0035] 8. Wire taking structure: adopt servo drive control method, driven by the third spiral transmission mechanism, to ensure that the finished wire harness accurately falls into the finished product wire taking slot, and the finished products and non-finished products are classified through program control.

[0036] Compared with the prior art, this case has the following advantages:

[0037] 1. Accurate positioning: The upstream mobile positioning structure 12, the downstream mobile positioning structure 5, and the wire-taking structure 2 adopt a spiral transmission structure driven by a servo motor. The servo motor monitors the state of the motor in real time through feedback devices such as encoders, thereby achieving precise position, speed and other control, which can cope with high load and high inertia load applications, has better stability and accuracy at high-speed operation, and can maintain stable speed and position during continuous operation;

[0038] 2. The first terminal crimping structure and the second terminal crimping structure adopt a bilaterally symmetrical structure setting, the first sheathing structure and the second sheathing structure adopt a bilaterally symmetrical structure setting, and the front stripping structure and the rear stripping structure adopt a bilaterally symmetrical structure setting, which can complete the processing of both ends of the wire;

[0039] 3. 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;

[0040] 4. Stripping length can be set: the stripping length at both ends of the wire can be set to different sizes through parameters;

[0041] 5. Both ends of the wire can be crimped with different types of terminals;

[0042] 6. Both long and short wires can be used;

[0043] 7. The wire-taking structure adopts a spiral transmission structure driven by a servo motor. The movement stroke is controlled by the program. The front end detects the feedback signal through optical fiber to determine whether it is a finished product, so that it can accurately fall into the finished product area or the non-finished product area.
