Vertical printing ink leveling machine

Abstract

The invention discloses a vertical printing ink leveling machine which comprises a rack. A clamping workbench is arranged on one side of the rack, a leveling workbench is arranged on the other side of the rack, a clamping conveying unit is arranged on the clamping workbench, and the clamping conveying unit is used for vertically clamping a product to be subjected to printing ink leveling and conveying the product to the leveling workbench. A printing ink vertical leveling unit is arranged on the leveling workbench; the printing ink vertical leveling unit comprises a double-machine-head carrying mechanism arranged on the leveling workbench, two tensioning mechanisms arranged on the two sides of the double-machine-head carrying mechanism correspondingly, two vertical leveling mechanisms arranged on the opposite outer sides of the two tensioning mechanisms correspondingly, and tension constant mechanisms arranged on one sides of the vertical leveling mechanisms correspondingly. The ink can be effectively prevented from moving or sinking, the yield of products is ensured, and the use of thin films is effectively saved, so that the production and processing cost is effectively saved.

Description

technical field [0001] The invention relates to the technical field of ink leveling processing equipment, in particular to an ink leveling machine which uses a vertical leveling mechanism to cooperate with a film on the surface of a product to be leveled with ink to perform vertical ink leveling operations. Background technique [0002] With the development of science and technology and the needs of product manufacturing, some PCB board processes have changed, and plug hole printing is required to match the process requirements. There are no lines passing through these parts of the PCB board, but holes are left, and ink needs to be used to block the partition, and the plug When making holes, it is necessary to completely fill the holes with ink. However, in actual production, because the holes on the circuit board are of different sizes, the thickness and uniformity of the ink cannot be guaranteed, so a double-sided leveling ink structure is required for leveling. , to ensur...

[0002] With the development of science and technology and the needs of product manufacturing, some PCB board processes have changed, and plug hole printing is required to match the process requirements. There are no lines passing through these parts of the PCB board, but holes are left, and ink needs to be used to block the partition, and the plug When making holes, it is necessary to completely fill the holes with ink. However, in actual production, because the holes on the circuit board are of different sizes, the thickness and uniformity of the ink cannot be guaranteed, so a double-sided leveling ink structure is required for leveling. , to ensure that the ink fills the hole

[0003] At present, the general practice is to use a roller-type ink leveling machine to level the product in a horizontal plane, act on both sides of the PCB board, cooperate with the film, and stick to the surface of the PCB board, so that the PCB board passes through the roller covered with film, Squeeze the ink to fill the holes on the PCB; however, since the PCB is placed horizontally, the ink in the holes will be affected by gravity, causing the upper surface of the ink filled in the product to be concave and the bottom surface to be protruding, and the product The surface will be uneven. During the extrusion process, excess ink will be produced, and the film will drive away the excess ink. The ink that is taken away will be squeezed out from both sides of the film and stain the equipment. , the equipment is placed in a dust-free workshop. If the ink stains the equipment, the ink will dry for a long time, resulting in dust, which cannot meet the dust-free requirements, and will affect the appearance of the equipment; During the ink leveling process, due to the large contact area, when the film is separated from the product, the leveled ink will be stuck out of the hole, resulting in unqualified products
