Feeding bin structure for heat pipe feeding, heat pipe rod pulling device and rod pulling method

Abstract

The invention discloses a feeding bin structure for heat pipe feeding. The feeding bin structure for heat pipe feeding comprises a feeding bin body, an ejection air cylinder and a rod taking structure, wherein the rod taking structure can jack up heat pipes in the feeding bin body one by one under the action of the ejection air cylinder; the rod taking structure comprises a plurality of first rod taking units and second rod taking units; a first groove is concavely formed in the top of each first rod taking unit; the protruding height of two limiting protruding parts on the two sides of each first groove is not larger than the radius of a heat pipe to be ejected out; a second groove is concavely formed in the top of each second rod taking unit; a first limiting part extends from one side of each second groove; the height of the part, protruding from the bottom of each second groove, of each first limiting part is larger than the radius of the heat pipe to be ejected out; a second limiting part extends from the other side of each second groove; and the height of the part, protruding from the bottom of each second groove, of each second limiting part is smaller than the radius of the heat pipe to be ejected out. The protruding height of at least one of the two limiting protruding parts is limited to be not larger than the radius of the heat pipe to be ejected out, so that only one heat pipe can exist in each groove at most during ejection every time.

Description

technical field [0001] The invention belongs to the technical field of heat pipe production equipment, and in particular relates to a feeding bin structure for heat pipe feeding, a heat pipe rod pulling device and a rod pulling method. Background technique [0002] The heat pipe is a special material with rapid temperature uniformity. Its hollow metal pipe body makes it light in weight, and its rapid temperature uniformity makes it have excellent thermal superconductivity. The application of heat pipe The scope is quite wide. It was first used in the aerospace field, and it has been widely used in various heat exchangers, coolers, natural geothermal energy, etc., and plays the role of rapid heat conduction. It is the most common and efficient heat conduction in today's electronic product cooling devices. (non-heat sinking) components.

AI Technical Summary

Problems solved by technology

[0003] The preparation of the heat pipe is generally made by sintering a layer of metal outside the mandrel. After the sintering is completed, the center rod, that is, the mandrel, is pulled out to make the heat pipe. The existing heat pipe loading and unloading usually uses It is time-consuming and labor-intensive to pull out one by one manually. When the central rod is bent and deformed or the surface is rough, the resistance is high and it is difficult to pull out, and the defective rate is high.
