Description

Technical Field

[0001] The present invention relates to the technical field of circuit board conveying, and more specifically, to a double-sided coated board conveying device. Background Art

[0002] The production of PCB is very complicated. Taking the four-layer printed circuit board as an example, its production process mainly includes the steps of PCB layout, core board production, inner PCB layout transfer, core board punching and inspection, lamination, drilling, copper chemical precipitation of hole wall, outer PCB layout transfer, outer PCB etching, etc. When transferring the inner PCB layout, the two-layer circuit of the middle core board (Core) must be made first.

[0003] After the copper clad laminate is cleaned, a layer of photosensitive film will be coated on its upper and lower surfaces to form a protective film on the copper foil on the upper and lower surfaces of the copper clad laminate. The bubbles and gaps generated during the lamination of the double-layer laminate cause the fit to decrease, affecting the quality of the product. At the same time, after lamination, they are directly stacked together and transferred to the next process. Adsorption force is generated between the protective films of the double-layer laminated boards stacked on each other, which can easily cause damage to the protective film during the removal process, increasing the damage rate of the product.

[0047] Working principle of the first embodiment:

[0048] During the conveying process of the coated plate 20, the protective film 22 on both sides of the coated plate 20 is smoothed by the linkage cooperation among the pressing part 9, the guide plate 13, the sliding part 16 and the smoothing part 18, and the bubbles between the substrate 21 and the protective film 22 are driven out and the internal gaps are removed, thereby improving the fit of the product and thus improving the quality of the product.

[0049] For example 2, please refer to Figure 1-15 The second embodiment makes the following improvements on the basis of the first embodiment. Specifically, sliding holes 23 penetrating the interior of the belt 6 are opened on both sides of the inner wall of the storage groove 8; the clamping part 9 includes a sliding rod 24 slidably arranged in the sliding hole 23; a ball head 25 is fixed to the end of the sliding rod 24; and a third spring 26 is connected between the ball head 25 and the side of the belt 6.

[0050] The sliding portion 16 includes a slide plate 27 slidably disposed in the slide groove 15 ; the two opposite side surfaces of the slide plate 27 are both rounded; a mounting plate 28 is fixed to the side surface of the slide plate 27 ; and a plurality of connecting springs 29 are symmetrically fixed between the mounting plate 28 and the side plate 12 .

[0054] In the initial state, the slide rod 24 is received in the corresponding slide hole 23, and the corresponding third spring 26 is in a normal state. When the corresponding ball head 25 slides to the oblique guide groove 14 at the end of the guide plate 13, the ball head 25 is squeezed to drive the slide rod 24 to slide in the direction close to the substrate 21. When the ball head 25 slides to the side of the guide plate 13, the clamping and fixing of both sides of the substrate 21 is completed, so that the coating plate 20 is clamped and fixed in the corresponding receiving groove 8.

[0055] When the ball head 25 slides in the oblique guide groove 14 toward the side of the guide plate 13, the slide plate 27 is squeezed, so that it slides synchronously with the mounting plate 28 in the direction away from the side plate 12, and the corresponding connecting spring 29 is stretched. During the sliding of the mounting plate 28, the lifting block 31 is pulled down along the guide rod 33 by the pull rope 19, and the corresponding mounting spring 34 is stretched, so that the two sets of rubber pressure rollers 73 move toward the direction of the protective film 22 close to the upper and lower surfaces of the substrate 21. When the ball head 25 moves to the side of the guide plate 13, the two rubber pressure rollers 73 just press the substrate 21. During the transportation of the coated board 20, the rubber pressure rollers 73 smooth the protective film 22 on both sides of the coated board 20 during the transportation process, drive out the bubbles between the substrate 21 and the protective film 22, and remove the internal gap, thereby improving the fit of the product and thus improving the quality of the product.

[0061] Working principle of the third embodiment:

[0062] In the initial state, the partition plates 44 on the corresponding partition parts 43 on the loading box 38 are stored in the corresponding positioning grooves 42, and the two insertion rods 55 are inserted into the insertion holes 48 on each group of connecting ears 47 from top to bottom in turn, and the turntable 57 is rotated so that the two groups of protrusions 58 are disengaged from the two guide balls 66, and the two guide balls 66 are pressed against the side surfaces of the turntable 57. The corresponding first springs 45 are compressed, so that the two groups of I-shaped plates 63 slide toward the direction close to the turntable 57, thereby driving the two groups of insertion rods 55 to slide close to each other synchronously, and driving the groups of partition plates 44 to slide close to each other and extend into the loading box 38, and the side door 68 of the loading box 38 is opened, and the coated boards 20 after coating are placed on the surfaces of the relative partition plates 44 in turn; the coated boards 20 at the bottom of the loading box 38 are placed in the storage groove 8 directly below.

[0063] In the initial state, the corresponding partition plates 44 on the storage box 41 extend into the interior of the storage box 41, and the two insertion rods 55 are inserted into the sockets 48 on each group of connecting ears 47 from top to bottom in sequence.
