Technical Field
[0001] The utility model relates to the technical field of defoaming devices, in particular to a defoaming device for the production of conductive silver paste. Background Art
[0002] A defoaming device for the production of conductive silver paste is a device used to remove bubbles in conductive silver paste. During the production process of conductive silver paste, due to operations such as material mixing, stirring, and heating, a large number of bubbles are often generated. If these bubbles are not removed in time, it will have an adverse impact on the performance of conductive silver paste, such as reducing the conductivity and affecting the uniformity of the coating. A defoaming device for the production of conductive silver paste usually consists of a vacuum device, a stirring device, a bubble separation device, etc. First, the conductive silver paste is put into the defoaming device, and the air in the device is pumped out by a vacuum pump to form a negative pressure environment. Next, the stirring device is started to stir the conductive silver paste, and at the same time, the stirring also promotes the floating of bubbles. Finally, the floating bubbles are separated from the conductive silver paste through the bubble separation device, so as to achieve the defoaming effect.
[0003] However, when some existing defoaming devices for the production of conductive silver paste are in use, most of them stir the conductive silver paste through a stirring rod. Due to the single stirring method, the conductive silver paste cannot be quickly and fully mixed with the materials, resulting in continuous generation of bubbles during the stirring process of the conductive silver paste. Therefore, this problem needs to be solved. Summary of the Utility Model

[0022] Refer to Figure 2 and Figure 4 , In a preferred embodiment, the mixing mechanism includes two limiting grooves 206. Both of the two limiting grooves 206 are opened in the lead screw 204. A limiting ring 207 is slidably connected to the inside of each of the two limiting grooves 206. Both of the two limiting rings 207 are sleeved on the surface of the same rotating shaft 202.

After the conductive silver paste and the material are placed inside the body 1, the feed port 101 can be closed, and then the inside is evacuated through the vacuum port 102. After the evacuation is completed, the motor 2 can be started. A first bevel gear 201 is installed on the output shaft of the motor 2, and the surface of the first bevel gear 201 is respectively engaged with a second bevel gear 203 and a third bevel gear 205. A lead screw 204 is installed at the bottom of the second bevel gear 203. Thus, when the first bevel gear 201 drives the second bevel gear 203 to rotate, the lead screw 204 can rotate synchronously. A sliding disk 3 is sleeved on the surface of the lead screw 204, and the sliding disk 3 is restricted by a limiting rod 302.

A limiting disk 405 is installed at the top of the main cylinder 4, and the limiting disk 405 slides on the top of the main cylinder 4 and is connected to the main cylinder 4 through a spring 406. Thus, when the sliding disk 3 moves downwards, the limiting disk 405 will also move downwards. A second mixing disk 403 is installed at the bottom of the limiting disk 405. Thus, the second mixing disk 403 will also move downwards synchronously to mix the conductive silver paste in the middle of the body 1. And the second mixing disk 403 cooperates with the first mixing disk 303. Thus, through the cooperation of the two, the conductive silver paste inside the body 1 can be fully turned over so that the conductive silver paste can be quickly blended with the material.
