## Abstract

A multi-layer and multi-cavity laminating machine including a multi-layer feeding device, at least two multi-layer laminating devices, and a multi-layer finished product conveying device connected in sequence is provided. The number of multi-layer laminating devices are increased, and the laminating steps are carried out step by step. After completing the first laminating step, the solar cell module can be transported to the next multi-layer laminating device, so that the next solar cell module can be transported to the previous multi-layer laminating device, thereby improving production efficiency. In the same production time, it is possible to increase the production quantity or reduce the production time by producing the same quantity of products.

## Claims

### Claim 1

A multi-layer, multi-cavity laminating machine, comprising a multi-layer feeding device, at least two multi-layer lamination devices and a multi-layer finished product conveyance device connected in sequence,
wherein each two adjacent multi-layer lamination devices are connected through a separate transitional conveyance device independently provided therebetween, and
the transitional conveyance device includes a support frame and multiple conveyor roller groups; the support frame is arranged between the two adjacent multi-layer lamination devices; the multiple conveyor roller groups are installed on the support frame and distributed from top to bottom at equal intervals; and multiple conveyor rollers of each of the conveyor roller groups are connected through chain drive and driven by a single motor.

### Claim 2 (depends on 1)

The multi-layer, multi-cavity laminating machine of claim 1, wherein an input end of the multi-layer feeding device and an output end of the multi-layer finished product conveyance device both are equipped with lift conveyance devices.

### Claim 3 (depends on 2)

The multi-layer, multi-cavity laminating machine of claim 2, wherein the lift conveyance devices each comprises an elevator, two lifting frames, and two belt conveyor bodies; both lifting frames are installed on the elevator and are parallelly distributed vertically; the two belt conveyor bodies are respectively mounted on the top of the two lifting frames.

### Claim 4 (depends on 1)

The multi-layer, multi-cavity laminating machine of claim 1, wherein the number of multi-layer lamination devices is two or three.
