Description

Technical Field

[0001] The utility model relates to the field of heat shrinkage devices for wire harness cables, in particular to a heat shrinkage tube baking and positioning device. Background Art

[0002] The technology of heat shrinking heat shrinkable tubes has been widely applied in wire harness production. However, the heat shrinking methods for heat shrinkable tubes at different positions are different. For example, the heat shrinking of heat shrinkable tubes connected to terminals is relatively simple, and an appropriate temperature can be selected by a heat shrinker for operation.

[0003] Currently, during the processing of wire harness cables, the process requires heat shrinking heat shrinkable tubes at the processing end of the cable to protect the internal electronic wires. The current process method is to stick tape on the board to indicate the position of the heat shrinkable tube. The staff places the cable on the board, then pulls the heat shrinkable tube to the position of the tape by hand, pinches the heat shrinkable tube with fingers, and bakes it with a hot air gun at the same time to complete the positioning and heat shrinking of the heat shrinkable tube.

[0004] However, the above method of indicating positioning by tape has low positioning accuracy and efficiency. Moreover, when manually pressing the heat shrinkable tube, the position of the heat shrinkable tube is prone to deviation during the heat shrinking process, resulting in deviation of the heat shrinking position of the product, inability to protect the internal electronic wires, and a high defect rate of the heat-shrunk cable. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the defects of the existing technology, such as low positioning accuracy and efficiency of indicating the positioning of heat shrinkable tubes by tape, poor stability of manually pressing the heat shrinkable tube, and easy deviation of the position of the heat shrinkable tube after heat shrinking, and to provide a heat shrinkable tube baking and positioning device.
