Problems solved by technology
[0002] In order to meet the needs of exposure positioning, the general exposure machine includes a horizontal drive mechanism for driving the displacement of the plate to be exposed along the X-axis and Y-axis, and a set of Z-axis for driving the displacement of the plate to be exposed. Axis drive mechanism, and the previous mechanism configuration method is usually to set the horizontal drive mechanism on the Z-axis drive mechanism. When the Z-axis drive mechanism is activated, it will also drive the horizontal drive mechanism to move up and down. However, such a mechanism configuration The disadvantage is that since the Z-axis drive mechanism also bears the weight of the horizontal drive mechanism, a motor with a relatively large torque needs to be provided. Moreover, the operating speed of the Z-axis drive mechanism is also reduced due to the weight of the horizontal drive mechanism. Easy to affect production capacity
[0003] At the same time, in order to improve production efficiency, it adopts a double-frame structure, and the corresponding Z-axis displacement drive device is only one, which needs to be adjusted when any one frame exits, and the single Z-axis displacement drive device, it may lead to inaccurate alignment
The two sets of exposure frames share a set of alignment mechanism, which increases the difficulty of machine installation and makes it difficult to achieve the consistency of the alignment effect of the two frames

Embodiment Construction
[0027] Embodiments of the present invention will be further described below in conjunction with accompanying drawings:
[0028] As shown in the figure, the present invention provides a solder-resisting independent alignment stage frame, including an upper stage frame 6 and a lower stage frame 1. The upper stage frame is provided with a glass plate and a vacuum structure for absorbing film. The rear ends of the upper frame 6 and the lower frame 1 are hinged to each other and the front ends can be opened and closed. The two opposite sides of the lower frame 1 are provided with opening mechanisms 8, and the bottom of the lower frame 1 is provided with a fixed bracket 2, and the fixed bracket 2. Cooperate with the lower frame, that is, the fixed bracket and the lower frame are fixed as a whole, and can move along the track on the exposure machine at the same time. A plurality of sliding parts are arranged on both sides of the fixed bracket 2 to slide and cooperate with the slide ra...
