Automatic feeding system for semi-flexible cable hot tinning process and automatic feeding method

Abstract

The invention discloses an automatic feeding system for a semi-flexible cable hot tinning process. The automatic feeding system comprises an automatic soldering flux adding system, an automatic tin adding system and a temperature control cabinet. The automatic soldering flux adding system comprises an automatic liquid pumping pump, a liquid storage tank, a transfer tank and a soldering flux tank,wherein a first infusion pipe is arranged between every two of the automatic liquid pumping pump, the liquid storage tank, the transfer tank and the soldering flux tank. A liquid level controller is arranged in each of the transfer tank and the soldering flux tank. The automatic tin adding system comprises a drum type tin ingot conveying belt, a pneumatic control valve, a piston air cylinder, a liquid level controller, an automatic tin adding tank and a tin tank. The tin liquid storage tank and the tin tank are connected through a second infusion pipe which is wound around a heating wire. Thetemperature of the liquid storage tank, the transfer tank, the soldering flux tank, the automatic tin adding tank, the tin tank and the heating wire are controlled by the temperature control cabinet.According to the system, an automatic soldering flux adding system and an automatic tin adding system are adopted, material adding can be realized without parking, and the production efficiency is improved; equipment is adopted for automatic mixing and feeding, the labor intensity is reduced, and the labor intensity is reduced; and the closed soldering flux feeding system enables the volatilization of the soldering flux to be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of cable production, in particular to an automatic feeding system for a semi-flexible cable hot-dip tinning process and automatic feeding thereof. Background technique [0002] PTFE insulated semi-flexible coaxial radio frequency cable, the shielding layer is made of tinned round copper wire braided and shielded and then dipped in tin as a whole.

Problems solved by technology

[0003] In the existing hot-dip tinning process for semi-flexible cables, both the tin bath and the flux bath are fed by parking. The tin ingot is added to the tin bath until it melts. It takes a long time for the temperature of the tin bath to stabilize. The flux and thinner need to be manually mixed. Then pour into the flux tank. In order to determine the timing of feeding, the operator needs to check the tin tank and flux tank from time to time. This feeding method greatly affects the production efficiency, and the labor intensity of the operator is also relatively high. Generally, a skilled operator can at most Responsible for two hot-dip tinning production lines

Moreover, for the convenience of observation, the flux tank is generally open, and the flux will volatilize quickly under the influence of high external ambient temperature, resulting in excessive loss of raw materials, polluting the surrounding environment, and endangering the occupational health of operators.
