Therefore, the bending performance and the corresponding material of the bending part of the electronic endoscope body have special requirements, and particularly the bending rubber at the outer layer of the bending part is required to have excellent aging resistance, excellent physical and mechanical properties and good tear resistance. In the production process of the electronic endoscope, the method of binding wires and then gluing and fixing is needed to be adopted to firmly fix the two ends of the bending rubber on the bending part when the bending rubber on the outer layer of the bending part is assembled. In order to reduce secondary damage to a human body in the process of inserting the bending part into the intestines and stomach of the human body as much as possible and reduce discomfort brought to the human body by inserting the bending part in the operation inspection process. Therefore, the requirement on the surface quality of the outer layer of the bending part is very high, the surface of the outer layer of the bending part is required to be smooth, and the gluing part is full and smooth.

In the rotary gluing process, if the outer surface of the gluing part is not smooth after glue is cured due to artificial factors, and the outer diameter of the gluing position of the bending part exceeds the upper limit of the specification due to gravity factors after gluing, assembling and gluing are carried out after re-assembly and disassembly.
