[0013] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0014] like Figure 1As shown, the base plate flattening mechanism includes a fixed roller group and a movable roller group. The fixed roller group includes a fixed frame 1 and a plurality of lower rollers 2 arranged in sequence side by side. The lower rollers 2 are rotatably mounted on the fixed frame 1. The movable roller group includes a movable frame 3 and a plurality of upper rollers 4 arranged in sequence side by side. The upper rollers 4 are rotatably mounted on the movable frame 3. The movable frame 3 is located directly above the fixed frame 1. The movable frame 3 is driven up and down by a lifting drive mechanism. The lower rollers 2 in the fixed roller group are driven to rotate by a rotating drive mechanism.
[0015] Furthermore, the fixed frame 1 is fixedly connected with a lower plate 5, and the movable frame 3 is fixedly connected with an upper plate 6. A rolling channel for the substrate to pass through is formed between the lower plate 5 and the upper plate 6. The lower plate 5 is provided with a plurality of lower extension ports 7, which correspond to the lower rollers 2 one by one. The upper end of the lower roller 2 extends into the rolling channel after passing through the corresponding lower extension ports 7. The upper plate 6 is provided with a plurality of upper extension ports, which correspond to the upper rollers 4 one by one. The lower end of the upper roller 4 extends into the rolling channel after passing through the corresponding upper extension ports. The lower plate 5 and the upper plate 6 can form a limiting effect on the substrate and improve the rolling effect.
[0016] Further, a lower synchronous chain ring is provided on one side of the fixed frame 1, and a lower gear 8 is fixedly connected to all the lower rollers 2, and the lower gear 8 is meshed with the lower synchronous chain ring.

The clamping gears 10 clamp the upper synchronous chain ring or the lower synchronous chain ring, so that the upper gear 9 and the lower gear 8 can always mesh with the upper synchronous chain ring or the lower synchronous chain ring, thereby preventing the upper synchronous chain ring or the lower synchronous chain ring from loosening.
[0018] Furthermore, the lifting drive mechanism includes a hydraulic cylinder 12, and guide rods 13 are respectively provided on both sides of the hydraulic cylinder 12, and the lower ends of the guide rods 13 are fixedly connected to the movable frame 3, and guide sleeves 14 are respectively sleeved on the guide rods 13, and the guide sleeves 14 are fixedly connected to the bracket, and the hydraulic cylinder 12 is fixedly connected to the bracket.
