[0002] Flexible assembly is usually applicable to the cable coating process in the fields of automobile manufacturing, electronic equipment manufacturing, aerospace, etc. This process coats multiple wires or cables at the same time to improve their durability, safety and reliability. During the coating process, the wires need to be kept in a straight state. This state is usually achieved by clamping the two ends of the wires or cables with a clamp and extending them to both sides for a certain length.

[0003] The current flexible stage generally requires manual adjustment of the distance between fixtures, has low precision, and lacks an alarm for changes in the distance between fixtures due to external force interference during the assembly process. To this end, we propose a flexible stage based on servo precision positioning. Utility Model Content

[0005] Preferably, a threaded column is provided on the top of the two sliding blocks, and an external thread is provided circumferentially on the threaded column. A blind hole is provided on the bottom of the two clamps, and an internal thread matching the external thread is provided in the blind hole. The two clamps can be detachably mounted on the threaded column, which can facilitate replacement and maintenance of the clamps.

[0006] Preferably, the two threaded rods are equal to the two slide rails in length.

[0007] Preferably, both ends of the two threaded rods are aligned with both ends of the slide rail on the same side in the vertical direction.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] First, clamp the two ends of the wire or cable into two clamps, then set the moving distance of the clamp through the control panel, control the rotation of the dual-axis servo motor through the control panel, and then rotate in opposite directions through the two threaded rods, drive the threaded sliders on both sides along the threaded rods and the bottom slide rails away from each other through the threaded transmission, and stop when reaching the preset distance, so that the wire or cable is in a straight state, and then perform the rubber encapsulation operation. During the operation, the distance sensor can obtain the distance between the two clamps. When the distance changes due to external force, the buzzer can be used to prompt the operator, and the error can be adjusted through the control panel, thereby reducing the impact of the error and improving the assembly accuracy.
