[0021] like Figures 1 to 7The composite material hot molding automatic production line shown in the figure comprises: hot molding equipment 1, a tool feeding system and a sheet feeding system, wherein the tool feeding system comprises a three-dimensional warehouse 2 storing a plurality of tools 01, a tool conveying line 3, and a first material taking component 4 for taking materials from the three-dimensional warehouse 2 and placing them on the tool conveying line 3; the sheet feeding system comprises a cutting machine 5 and a transfer trolley 6 for transferring the cut sheet 02; The hot molding equipment 1 is arranged between the tooling feeding system and the sheet feeding system, and the hot molding equipment 1 comprises a hot molding area, and a second material taking component 7 and a third material taking component 8 arranged in the hot molding area corresponding to the tooling feeding system and the sheet feeding system; The second material taking component 7 is used to transfer a plurality of tooling 01 on the tooling 01 conveying line to the hot molding area one by one; The third material picking assembly 8 is used to transfer the material sheet 02 on the transfer trolley 6 to the tooling 01 at the corresponding position.

[0022] In the implementation process of the present invention, the cutting machine 5 accurately cuts the material sheet 02 according to the production requirements. After the cutting is completed, the robot arm places the cut material sheet 02 on the transfer trolley 6, and the transfer trolley 6 moves along the preset ground track until it reaches one side of the hot molding equipment 1; at the same time, the first material picking component 4 transfers the tooling 01 in the stereoscopic library 2 to the tooling conveyor line 3, and the second material picking component 7 transfers several toolings 01 on the tooling conveyor line 3 to the hot molding area one by one to form a preforming mold, and starts to descend through the upper module of the equipment, and descends to the upper plane of the tooling 01, and uses the cylinder to realize the connection between the tooling 01 and the upper mold, and then the upper mold and the lower mold of the preforming mold are separated through the upper module; at this time, the third material picking component 8 transfers the material sheet 02 on the transfer trolley 6 to the preforming mold that has been composed of the tooling 01, and the hot molding equipment 1 starts to perform the molding operation. Under the conditions of high temperature and high pressure, the material sheet 02 is pressed into the desired product shape. The present invention forms an automated production line by arranging a tool feeding system and a sheet feeding system, and can realize uninterrupted feeding of the hot molding equipment 1, thereby ensuring the continuity and stability of production and improving production efficiency.

[0023] In the present invention, the three-dimensional warehouse 2 is provided with several layers of storage areas; the three-dimensional warehouse 2 adopts a multi-layer design, which can greatly improve the utilization rate of the warehouse space, and the single-layer storage area is provided with several tooling 01 along the moving direction of the tooling conveyor line 3, so that the tooling 01 can be compactly arranged, so that the tooling 01 can be quickly taken out from the three-dimensional warehouse 2 and conveyed to the hot molding equipment 1, reducing the waiting time of the production line and improving production efficiency.

[0024] In the preferred embodiment of the present invention, a pallet is provided under the tooling 01, and the first material-retrieving component 4 realizes the transfer of the tooling 01 between the three-dimensional warehouse 2 and the tooling 01 conveyor line through the pallet. The pallet provides a stable support platform for the tooling 01, so that the first material-retrieving component 4 can more easily locate and grab the tooling 01, reducing the time waste during the transfer process and improving the transfer efficiency. In addition, the presence of the pallet reduces the direct contact between the tooling 01 and the three-dimensional warehouse 2 and the tooling conveyor line 3, thereby reducing the risk of damage to the tooling 01 due to friction or collision.

[0025] As a preferred embodiment of the above embodiment, the tooling 01 includes an upper mold and a lower mold, which are connected by guide pillars; when closed, deviation and misalignment of the upper mold and the lower mold can be avoided, thereby reducing the molding error caused by mold misalignment, and the lower mold is fixed on the platform of the hot molding equipment 1, and the upper mold is connected to the upper module of the hot molding equipment 1, which is convenient for rapid replacement of molds of different specifications or types, helps to adapt to the production needs of different products, and improves the flexibility and efficiency of the production line.

[0026] Specifically, the connection method between tooling 01 and the equipment is as follows: first, tooling 01 is moved as a whole, and the overall mold is positioned and placed on the equipment through the guide pins on the heating plate. After that, the upper module of the equipment is pressed down to the upper plane of tooling 01, and the connection between tooling 01 and the upper mold is achieved through the cylinder-driven connecting column.

[0027] In order to save the waiting time for the transfer of tooling 01, at least two tooling conveyor lines 3 are provided; and the two tooling conveyor lines 3 are arranged in parallel, and the second material taking component 7 reciprocates along the transfer direction of the tooling conveyor line 3 to realize the alternating feeding of the tooling 01 in the hot molding equipment 1 by the two tooling conveyor lines 3. Through the reciprocating movement of the second material taking component 7, the two tooling conveyor lines 3 can work together to realize the rapid and accurate cyclic transfer of tooling 01.

[0028] In a preferred embodiment of the present invention, the first material picking component 4 includes an elevator 41, a material picking platform 42 and a linear drive component 43; the material picking platform 42 is arranged on the lifting platform of the elevator 41, and the linear drive component 43 supports and drives the elevator 41 to reciprocate along the length direction of the three-dimensional warehouse 2, thereby realizing the storage and retrieval of the tooling 01 in the three-dimensional warehouse 2.

[0029] The lift 41 moves the material-collecting platform 42 in the vertical direction, so that the tooling 01 can quickly reach the designated position. The linear drive 43 can support and drive the lift 41 to move quickly and reciprocatingly along the length direction of the stereoscopic warehouse 2, which greatly shortens the access time of the tooling 01 and further improves the access efficiency.

[0033] Specifically, the setting of the sliding component 833 allows the spacing between the suction cup components 832 to be flexibly adjusted according to the size and shape of the material 02, which is suitable for the adsorption of a variety of different types of materials 02, thereby improving the versatility and adaptability of the equipment; and in order to meet the handling stroke, the linear module 82 adopts a two-way stroke to meet the needs of transferring the material 02 on the transfer trolley 6 to the hot molding area; the entire material 02 adsorption and transfer process is completed by automated components such as the linear module 82, the stepper motor 8334 and the spiral elevator 84, without the need for human intervention, thereby greatly improving production efficiency.
