Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only for the purpose of illustration and explanation, and not limitation.

Example 1

As shown in fig. 1-5, the utility model relates to a copper terminal wicking device, including hollow shelf 1 and copper terminal rack 2, hollow shelf 1 is a top and all sealed, the open tank tower in bottom all around, and trompil 3 that is used for placing copper terminal rack 2 is offered at hollow shelf 1's top surface center, copper terminal rack 2 is the frame plate of a rectangle structure, evenly offers a plurality of on copper terminal rack 2's the face and is used for placing copper terminal place hole 4, and the fixed handle 5 that is used for wicking that is provided with in both sides department that copper terminal rack 2 top is located its length direction.

In this embodiment, the area of the copper terminal placing frame 2 is larger than the area of the opening 3, and the maximum area of the placing hole 4 region is smaller than the area of the opening 3; the length of trompil 3 is 265mm, and the width is 190mm. The length of copper terminal rack 2 is 270mm, and the width is 195mm.

In this embodiment, as shown in fig. 6, the operation and use method of the whole apparatus is as follows:

firstly, suspending a plurality of copper terminals in a placing hole 4, lifting the whole copper terminal placing frame 2, horizontally placing and dropping, and immersing the bottoms of the copper terminals into a container filled with soldering flux to complete the soldering flux immersing process of the copper terminals;

secondly, suspending the copper terminal placing frame 2 soaked with the soldering flux on a container or on a hollow shelf 1, and dripping the residual soldering flux on the copper terminal;

thirdly, correspondingly placing the hollow shelf 1 on the top of a tin melting furnace 7, wherein the tin melting furnace 7 is filled with metallic tin, the hollow shelf 1 just faces the tin liquid and is positioned above the metallic tin, then placing the copper terminal placing frame 2 soaked with the soldering flux into the open hole 3 of the hollow shelf 1, starting the tin melting furnace at the moment, and raising the temperature to about 300 ℃, wherein on one hand, the metallic tin in the tin melting furnace 7 is gradually melted into the tin liquid, and on the other hand, in the melting process of the metallic tin, the high temperature of the tin melting furnace 7 synchronously heats the copper terminals on the copper terminal placing frame 2 and dries the soldering flux, so as to synchronously complete the preheating of the copper terminals;
