Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automatic exposure, in particular to a double-sided exposure device. BACKGROUND

[0002] In recent years, with the rapid development of electronic technology, the demand for improving production capacity of PCB industry has increased dramatically. The production capacity of the traditional full-automatic exposure machine in the solder mask exposure process can only reach 3-3.5 pieces per minute, and the design usually adopts single-sided exposure and single-frame operation. In the past two years, some enterprises have changed the traditional design method and adopted single-sided exposure and double-frame operation design, and the production capacity can reach 5-6 pieces per minute. Even so, the growing demand still cannot meet the needs of the current circuit board manufacturing industry.

[0003] Based on the need to expose both sides of the PCB, after completing the exposure of one side of the board, the board needs to be flipped by a flipping mechanism for exposure of the other side. The existing automatic exposure equipment has a large overall size, occupies a large area, has a long connection action CT, and has low overall production capacity. The exchange plate process is complex and requires two devices to expose the AB sides of the product. Moreover, the traditional double-sided exposure machine is generally fixed for a certain type or size of board, or needs to be stopped for manual distance adjustment to replace the corresponding pickup or clamping mechanism, which undoubtedly leads to poor versatility and low efficiency of the device.

After the board is calibrated and positioned by the positioning mechanism after passing through the feeding mechanism, the board is transferred to the first exposure device by the mechanical hand of the first transfer unit for exposure. After exposure is completed, the flipping mechanism lifts and flips the board so that the unexposed side of the board faces outward, and at the same time the mechanical hand adsorbs the unexposed side of the board and transfers it to the second exposure device for exposure. After the double-sided exposure of the board is completed, the board is transferred to the discharging mechanism by the mechanical hand for discharging and stacking. The flipping mechanism is provided in the first exposure device and the second exposure device, so that the double-sided exposure device can realize double-sided exposure.

[0040] The positioning mechanism 2 in the embodiment adopts the specific structure described above. When positioning, the feeding mechanism 1 delivers the plate 9 to the positioning frame 22. The transverse positioning mechanism 23 can limit the plate 9 at a transversely set position at the discharging end of the feeding mechanism 1. Meanwhile, in combination with the longitudinal positioning mechanism 24, the plate 9 can be limited at a longitudinally set position at the discharging end of the feeding mechanism 1. Specifically, when the transverse positioning mechanism 23 is positioned, first, the first driving assembly 233 is used to drive the first positioning piece 231 to move transversely along the feeding direction of the plate 9 to a set position, so that the first positioning piece 231 can limit the plate 9 at a set transverse position.
