Referring to fig. 1 to 6, in the embodiment of the present application,

a coating machine of pcb board, the coating machine 100 includes the frame 1 and locates the delivery roller 2, upper coating roller 3 and lower coating roller 4 on the frame 1, send the black head 5 and platen roller 6.

In a specific use, the pcb panel is uniformly inked by coating between the upper coating roller 3 and the lower coating roller 4, wherein, in order to enhance the uniformity of the ink, an ink-distributing roller 31 is arranged in parallel and tangent to the upper coating roller 3, and rotates following the upper coating roller 3 by the ink-distributing roller 31.

An ink feed head 5 is provided along the ink fountain 31 at a position tangent to the upper coating roller 3, and ink is gradually fed between the ink feed head 5 and the upper coating roller 3 to ensure coating supply between the upper coating roller 3 and the lower coating roller 4.

In order to improve the smoothness of the pcb, the pcb is further pressed to ensure the corresponding smoothness by utilizing the working principle of rolling. Therefore, a platen roller 6 is also provided on the machine base 1.

In the rolling process, the conveying roller 2 is guaranteed to be conveyed into the pcb between the upper coating roller 3 and the lower coating roller 4 to be relatively integral, and therefore the pressure plate roller 6 is arranged to comprise a pressure plate bottom roller 61 and a pressure plate pressing roller 62.

In a specific use, the pcb board is rolled by the platen roller 62 moving over and following the platen base roller 61, and the feeding of the pcb board is ensured to be stable by the platen base roller 61 being flush with the feed roller 2.

Preferably, in order to increase the weight of the pressing plate pressing roller 62, the pressing plate pressing roller 62 is a roller with different weight, so that different pressing forces are realized, and therefore, a first groove block 64 and a second groove block 65 for assisting the pressing plate pressing roller 62 to move are respectively arranged along two sides of the pressing plate pressing roller 62, and the pressing plate pressing rollers 62 with different weights can be placed through the open structures of the first groove block 64 and the second groove block 65.

As shown in fig. 2, in the embodiment of the present application,

in order to further ensure that the pressing force of the pressing plate pressing roller 62 on the pcb is uniform and does not jump, a weighting roller 63 moves along the pressing plate pressing roller 62, and the end of the weighting roller 63 is also inserted into the first groove block 64 and the second groove block 65.
