Before the prepreg is laid, it is placed on a table 27, and a positioning cylinder 28 is provided on the table 27.
[0019] The loading robot is connected to a suction cup frame 6 at its end, and multiple vacuum suction cups are installed on the suction cup frame 6; after the positioning cylinder 28 positions the placed prepreg, it is then picked up and removed by the loading robot 1. The loading position of the loading robot 1 is located in the middle of the laying platform 2. Above the laying platform 2, on the upper frame of the front and rear sides of the loading position, bushings 3 are respectively installed. Material rolls 7 can be detachably installed in bushings 3. In this embodiment, the material rolls include umbrella cloth rolls and plastic film rolls. The umbrella cloth rolls and plastic film rolls are placed on the front and rear sides of the loading position, respectively. During laying, the plastic film on the rear side is laid on the bottom layer, followed by the umbrella cloth; then the carbon fiber prepreg is placed; then the umbrella cloth on the front side is laid on the top side, and the outermost layer is the plastic film on the front side. The laying platform 2 is also equipped with a guide roller 8 on its upper side. During the laying process of the material being rolled onto the carbon fiber prepreg, it passes around the guide roller 8, which facilitates the laying operation.
[0020] On both sides of the laying platform 2, the loading positions of the loading robot 1 are also equipped with rotary pressing cylinders 9. This prevents the prepreg from being unloaded by the suction cups in the suction cup frame 6, or from following the suction cups in the suction cup frame 6. A row of smoothing bristles 10 is also provided on the front side of the laying platform 2; a cutting blade 4 is installed at the front end of the laying platform 2, which is driven by a rodless cylinder to move back and forth from the left and right sides of the laying platform 2; a cylinder is installed on the left and right sides of the cutting blade mounting bracket; at the outer end of the laying platform 2, a notch corresponding to the pneumatic gripper is provided on the platform for easy gripping; a long suction nozzle vacuum cleaner 11 is provided on the lower side of the cutting blade 4; the suction nozzle has the same stroke length as the cutting blade 4; the vacuum cleaner 11 sucks up the material debris that falls during cutting to prevent it from affecting product quality.
[0021] Near the cutting blade, on both sides of the support of the paving platform, there are clamping cylinders 12 respectively.
[0022] A support brush 13 is provided near the cutting blade. The support brush 13 prevents the material below from collapsing downwards. Cutting is then performed with the support of the support brush 13 to ensure that all material is cut through.
[0023] The paving platform is also equipped with a material roll feeding rack, which includes a roll frame 14, a second hoist 15, and a traveling beam 16. The second hoist 15 is installed on the traveling beam 16, and the motor drives the traveling wheels to travel on the traveling beam, thereby moving the second hoist 15.
[0024] In the chain conveyor mechanism, a common slide rail 17 is installed on the upper frame, and two sliders are connected to the common slide rail 17. A connecting frame is installed on one slider, and a set of vacuum grippers 5 are installed on the connecting frame. A suction cup frame 2 18 is connected to the other slider, and multiple vacuum suction cups are installed on the suction cup frame 2 18. The connecting frame and the suction cup frame 2 18 are moved by a motor driving gears to run on a rack. A chain 19 is installed in the lower frame of the chain conveyor mechanism. A power motor is connected to the chain 19, and the motor drives the chain to move. A support beam 20 is installed in the chain, and a pallet table 21 is placed on the chain 19 and transported to the hoisting mechanism. The hoisting mechanism includes a hoisting frame 22; a power rail 23 is provided on the upper side of the hoisting frame 22, a hoisting hoist is installed between the rails, and a hoisting frame 24 is connected to the lower side of the hoisting hoist.

The guide posts ensure the lifting frame is stable and does not wobble during vertical movement; the springs provide a buffering effect after the lifting frame has reached its designated position.
[0025] The power track consists of a slide rail, a slider, and a rack and pinion motor assembly. The slide rail is fixed to the upper side of the hoisting frame, and a slider is fitted on the slide rail. A hoisting hoist is installed between the sliders. A rack is installed on the hoisting frame, and a gear is connected to the output end of the motor. The motor drives the gear to move on the rack, thereby moving the hoisting hoist. Example 2
[0026] The working method of the prepreg laying equipment in Example 1 includes the following steps: Step 1 Initial preparation: The material roll is loaded onto the material roll by the material roll feeder and installed in the bushing 3; During the initial work, on the laying platform 2, the material on the rear material roll is laid on the lower layer of carbon fiber prepreg and manually stretched to the position of the pneumatic gripper 5. In the area between the cutting blade 4 and the feeding position, the carbon fiber prepreg is manually placed on the lower layer of material; the material on the front material roll is laid on the upper layer of carbon fiber prepreg and is also stretched to the position of the pneumatic gripper 5. Step 2: Loading and Laying: The carbon fiber prepreg is placed on the table 27 by the operator. After being positioned by the positioning cylinder 28, the loading robot 1 picks up the carbon fiber prepreg from the table and transfers it to the robot loading position on the laying platform. All subsequent loading is operated by the loading robot 1. When the rotary pressing cylinder 9 is installed, the carbon fiber prepreg contains adhesive. When it is placed down, it will not fall off the suction cup. Therefore, the rotary pressing cylinder 9 is set at the four corners after the carbon fiber prepreg is placed. After the suction cup frame 6 puts the material down, the rotary pressing cylinder 9 rotates to the position first and then presses down to hold the carbon fiber prepreg in place. Then the loading robot 1 leaves with the suction cup frame 6 for the next material picking and loading. When the smoothing brush 10 is provided, the material passes under the smoothing brush 10 to smooth the upper layer of material and prevent wrinkles. In this embodiment, both the lower and upper materials are two layers, symmetrically distributed on both sides of the carbon fiber prepreg. The two layers are umbrella fabric and plastic film. Step 3: Loading and conveying steel plates: On the chain, the forklift loads the pallet table 21 and transports it to the work station by the chain 19; the suction cup frame 28 is driven by the motor to pick up the steel plate with the suction cup and load it from the raw material to the pallet table 21; before the steel plate is placed, the surface of the pallet table 21 is sprayed with a high-pressure air gun; after the steel plate is placed, the surface of the steel plate is sprayed again. Pulling and conveying: The motor drives the connecting frame and pneumatic grippers 5 to move to the gripping position. Multiple pneumatic grippers 5 simultaneously grip the upper and lower sides of the laid material; after gripping, the material is pulled onto the pallet table 21. Step 4 Cutting: When the gripper cylinder 12 is installed, the gripper cylinder 12 grips both sides of the material; after the pneumatic gripper 12 pulls the material into place, the cylinder drives the mounting frame to press down, and the cutting blade 4 runs to cut the material; then repeat steps 2 to 4; lay a layer of steel plate on a layer of laying material, and after reaching the number of layers required for the next process, proceed to step 5; Step 5 Conveying: Chain 19 conveys the pallet table to the hoisting mechanism position. Hoist 1 lowers the hoisting frame, cylinder 26 extends. When cylinder 26 extends, the gripping frame opens outward, expanding to the outer edge of the pallet table. After cylinder 26 retracts, the lower side of the gripping frame is inside the lower inner edge of the pallet table 21. After hoist 1 hoists, the power rail drives the hoisting frame to move to the unloading position.
