[0034] Step 1: Place the cut copper clad laminate into the WIP storage location;

[0035] Step 2: AGV takes out the copper clad laminate from the WIP storage location and transports it to the board loading and unloading station;

[0036] Step 3: Align the copper clad laminate and adjust it to a horizontal state;

[0037] Step 4: The aligned copper-clad laminate is stacked horizontally by the automatic stacking device according to the system preset formula requirements;

[0038] Step 5: Preheat the stacked copper clad laminates;

[0039] Step 6: According to the system preset recipe requirements, the system sends the baking parameters to the baking temperature zone, and bakes the stacked copper clad laminates through multiple baking temperature zones set in sequence;

[0042] Step 9: The AGV takes the copper clad laminate from the transport pallet and transports it to the WIP location.

[0043] like Figure 1 As shown, the fully automatic baking processing method after copper clad laminate cutting adopts the fully automatic multi-layer stacking baking process after copper clad laminate cutting, which includes the steps of WIP storage location, AGV transportation, centering, automatic stacking and placing boards, preheating, baking, cooling, automatic board collection, AGV transportation and other steps. Through this process, the automatic handling, centering, stacking and placing boards, preheating, baking, cooling and automatic board collection of copper clad laminates are realized, which improves production efficiency and reduces production costs. This technical solution uses AGV transportation to transport copper clad laminates into and out of baking equipment, realizes the automatic handling of products, improves production efficiency and reduces production costs.

[0044] The equipment is used to automatically complete the centering and horizontal stacking of copper clad laminates instead of manual work, which improves the automation of baking preparation work. The automated production method is adopted, without manual operation, and each step can be traced. Through this design, the intelligent automated manufacturing and production of the product is realized, the stability of product quality is improved, and the problem of human errors in the existing technical process affecting the stability of product quality is solved.

[0045] The traditional baking process requires manual operation, which is inefficient and cannot realize the intelligent and automated manufacturing and production of products. The existing baking process is mainly manual operation, and vertical cabinet furnaces are usually used for production. The fully automatic baking process method after copper clad laminate cutting is adopted to realize the intelligent and automated design of the baking process. There is no manual operation in the process and each step of the process can be traced, which solves the problem of low baking efficiency of existing products. Through the intelligent and automated production process design, the baking efficiency of products is improved. The problem of high energy consumption of the existing vertical cabinet furnace production method is solved. By optimizing the production process and equipment, energy consumption is reduced, which is conducive to energy conservation and emission reduction. The problem that the existing technology cannot realize the intelligent and automated manufacturing and production of products is solved, and the intelligent and automated manufacturing and production of products is realized. The problem of human errors in the existing technology process affecting the stability of product quality is solved. Through the intelligent and automated production process design, human errors are reduced and the stability of product quality is improved.

[0046] The following is a specific processing example to illustrate the fully automatic baking processing method after the copper clad laminate is cut:

[0047] First, the copper clad laminate to be processed is placed in the WIP storage location. The temperature of the WIP storage location is controlled between 20℃ and 30℃, and the humidity is controlled between 50% and 60%. The AGV (automatic guided vehicle) takes the copper clad laminate to be processed from the WIP storage location and transports it to the board entry station. The transportation speed of the AGV is controlled between 0.5m / s and 1.0m / s. The copper clad laminate is placed on the centering device in the board entry, and the centering device adjusts the copper clad laminate to a horizontal state. The copper clad laminate after centering is automatically stacked by the board placement device according to the system preset formula requirements, and two stacks of products can be placed on the same horizontal plane. The stacked products are preheated by hot air circulation, and the preheating temperature is controlled between 50℃ and 100℃, and the preheating time is 10 minutes to 30 minutes. According to the system preset formula requirements, the baking parameters are released by the system, and there are ten baking temperature zones and the temperature of each temperature zone is independently controlled. The number of stacks of products baked in a single temperature zone is two. The baking temperature is controlled between 100℃ and 200℃, and the baking time is 10 minutes to 60 minutes. The stacked products are cooled by cold air circulation, and the cooling temperature is controlled between 0℃ and 30℃, and the cooling time is 10 minutes to 30 minutes. The cooled products are automatically collected horizontally according to the preset formula requirements of the system, collected to the transport tray, and transported by AGV. The AGV takes out the copper clad laminate to be transported from the automatic board collection station and transports it to the WIP warehouse. The transportation speed of the AGV is controlled between 0.5m / s and 1.0m / s. Through the above steps, the automatic handling, centering, stacking, preheating, baking, cooling and automatic board collection of the copper clad laminate are realized, which improves production efficiency and reduces production costs. At the same time, the entire process is intelligent and automated, and each step can be traced, which improves the stability of product quality.

[0048] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
