[0001] The utility model relates to the technical field of red ink impregnation equipment, in particular to a full-automatic red ink impregnation equipment. Background Art

[0002] Based on the quality inspection requirements of circuit boards, red ink immersion is used for inspection. By placing the circuit board in red ink and vacuuming to create negative pressure, the red ink penetrates into the defects of the circuit board, which can improve the inspection accuracy.

[0003] The red ink impregnation equipment currently on the market usually uses a container filled with red ink. The circuit board to be inspected is placed in the container and the red ink is infiltrated by vacuuming. This method has certain disadvantages, because the production and storage of circuit boards are exposed to the air, and the defects may adhere to residues in the air, making it impossible for the red ink to penetrate. This will lead to misjudgment of the quality inspection of the circuit board, causing defective products to flow into the next process, causing greater quality problems. Therefore, it is urgent to design a fully automatic red ink impregnation equipment to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is: before products such as circuit boards enter the red ink, the products are vacuumed to extract some residues in the product defects, and then the products are immersed in the red ink for infiltration, so as to avoid the residues remaining in the product defects not being removed cleanly, resulting in misjudgment of product quality inspection and avoiding other quality problems.

[0031] The tank body 2 is filled with red ink, and the red ink level is located in the middle of the tank body 2. The lifting mechanism 8 drives the lifting seat 9 to lift and lower between the red ink level in the middle of the tank body 2 and the bottom of the tank body 2. The basket 10 is provided to support the circuit board, and then the basket 10 is placed on the lifting seat 9. The tank body 2 is filled with red ink to the middle of the tank body 2. The cover 7 is buckled on the tank body 2 by the opening and closing cover mechanism 5. The vacuum is evacuated by the vacuum pump 11 to perform the first vacuum operation, so as to extract the residues in the defects of the circuit board. By setting a lifting mechanism 8 to drive the lifting seat 9 to move downward to the bottom of the tank body 2, the basket 10 containing the circuit board is immersed in the red ink, and then the vacuum pump 11 is used to evacuate the vacuum again to perform a second dehumidification and vacuum operation, thereby completing the impregnation work.

In the initial state, the lifting seat 9 is located in the middle position of the tank body 2. The circuit board is placed in the basket 10. The red ink is poured into the tank body 2 so that the red ink liquid level is located in the middle position of the tank body 2. The red ink liquid level is flush with the lifting seat 9 or is located below the lifting seat 9. The basket 10 with the circuit board is placed on the lifting seat 9. After starting, the switch cover mechanism 5 drives the cover body 7 to buckle on the tank body 2. The cover body 7 rotates first. When the cover body 7 moves to the top of the tank body 2, the cover body 7 moves downward to buckle on the tank body 2. A sealing ring is provided at the edge of the opening of the tank body 2 to ensure that the cover body 7 can ensure the sealing of the inside of the tank body 2 when it is buckled on the tank body 2. Then the vacuum pump 11 evacuates the vacuum to perform a vacuum operation so that the residues in the defects of the circuit board are extracted dry. After the circuit board on the basket 10 is drained for a period of time, the switch cover mechanism 5 drives the cover body 7 to be removed from the tank body 2.
