Description

Heating full-automatic solder paste stirrer

Technical Field

The utility model belongs to the technical field of the solder paste agitated vessel technique and specifically relates to a full-automatic solder paste mixer of heating is related to.

Background

The full-automatic solder paste stirrer is a machine which utilizes the principle of planet-like operation, namely the stirring action of revolution and rotation to uniformly stir solder paste and defoam the solder paste. The solder paste processed by the solder paste stirrer has the characteristics of uniformity, fineness, luster and no air bubble, thereby realizing more perfect printing and reflow soldering effects of SMT (surface mount technology). The structure of the existing solder paste stirrer is as follows: 201220282363.5, and 201520092386.3, but the existing solder paste agitator has no shock absorption function, and the structure of the existing solder paste agitator is too simple, and there is no structure for increasing the dead weight of the body to offset the vibration of the body. In order to ensure that the vibration of the whole machine caused by unbalance is reduced to the minimum, two bottles of solder paste with equal weight or one bottle of solder paste and a balancing weight with the same weight are required to be placed to achieve balance when the device is used. However, in the actual use process, the situation of unmatched weight often occurs, if the unused solder paste needs to be stirred and defoamed again, so that the weight cannot be matched with the balancing weight, and the unused solder paste and a new bottle of solder paste are simultaneously put on the machine for stirring and defoaming. Particularly, when the solder paste stirring machine rotates at a high speed, the machine vibration is inevitably too large, and the service life, noise and uniformity of solder paste stirring of the machine are all affected by the vibration of the whole machine. Meanwhile, when the solder paste stirrer works, a solder paste cup filled with solder paste needs to be placed on the solder paste seat, and the solder paste cup can shake in the solder paste seat due to the vibration of the machine, and even fall out of the solder paste seat, so that the uniformity of solder paste stirring is influenced, and the solder paste cup can be damaged.

In addition, the solder paste is usually refrigerated in a refrigerator to maintain its activity, and the refrigerating temperature is preferably 5 to 10 ℃. Therefore, when the solder paste is taken out from the cold box, the temperature is much lower than the room temperature, and if the bottle cap is opened without 'returning to the temperature', the water vapor in the air is easy to condense and is adhered to the solder paste. Therefore, the solder paste must be warmed before being stirred. The existing temperature return mode comprises the following steps: naturally thawing the mixture in room temperature without opening the bottle cap, and returning to the temperature for a period of time: more than 4 hours, the method has long time and low efficiency. If in winter, when room temperature can't satisfy the requirement, need to use firing equipment to carry out the tin cream heating, the time of rising the temperature: 30 minutes to 1 hour. However, the existing heating equipment for heating the solder paste and the solder paste stirrer are mutually independent, the occupied area of the equipment is large, the production cost is increased, meanwhile, the heated solder paste needs to be taken out and then placed in the solder paste stirrer, the operation is complex, and the production efficiency is reduced.
