[0003] The production process of the solder mask is roughly divided into: pre-treatment before solder mask → printing / pre-baking → exposure → development. The main function of the printing link is to print the ink on the circuit board by screen printing, covering a layer of protective solder mask oil on the board surface to protect the circuit board from the influence of the external environment. These inks will be added with a curing agent and stirred before screen printing to make the viscosity and thixotropy of the ink reach the required range for production. The existing stirring method is to pour the ink and the curing agent into the ink bucket, and then start the motor to drive the ink bucket to rotate, and stir the ink and the curing agent in the bucket through the stirring head installed above the ink bucket. When stirring the ink in this way, the stirring head is fixed and does not rotate, and only the ink near the stirring head has a good stirring effect. The required stirring time is long, the stirring efficiency is low, and a uniformly excellent solder mask ink cannot be obtained.

[0004] Based on this, the utility model designs a solder mask ink stirring device to solve the above problems. Content of the Utility Model

After the input is completed, the start button is pressed. At this time, the ink bucket rotates under the action of the first motor, and the stirring head rotates in the opposite direction under the action of the second motor, thereby accelerating the fusion process of the ink and the curing agent. At the same time, during the stirring process, the stirring head starts to move slowly up and down.

At the same time, the rotating frame is rotated through the second driving source to make it fit with the stirring head. Subsequently, the first driving source is controlled to make the first gear rotate, and then the cleaning plate rotates around the stirring rod, thereby cleaning the residual materials on the upper side of the stirring head, and then avoiding the waste of materials caused by the residual materials on the stirring head. At the same time, when the equipment needs to be cleaned, only the above operations need to be repeated, and the liquid supply component is controlled to inject liquid into the cleaning plate, and the cleaning of the equipment can be completed, thus effectively improving the cleaning efficiency of the equipment and ensuring the cleanliness of the equipment.
