[0063] The present embodiment provides an automatic loading and unloading device for SMT templates, which is a device for automatic loading and unloading of SMT templates by laser cutting, and can realize automatic loading and unloading of a single machine.

[0064] refer to Figure 1 The SMT template automatic loading and unloading equipment of this embodiment includes a lifting frame 1, a shelf 2, a lifting conveyor line 3, a material taking mechanism 4 and a positioning mechanism 5.

[0065] The lifting frame 1 is used to raise or lower the lifting conveyor line 3 and the material-retrieving mechanism 4 to a specified position of the shelf 2. For example, the lifting frame 1 is a screw lifting frame, and the lifting conveyor line 3 and the material-retrieving mechanism 4 are raised or lowered to a specified position by the screw.

[0066] Shelf 2 is used to place multiple SMT templates. For example, refer to Figure 3 The shelf 2 includes a plurality of cargo layers 201 ; each cargo layer 201 can be used to place an SMT template.

[0067] The material taking mechanism 4 is used to take the SMT template out of the shelf 2 and place the SMT template on the lifting conveyor line 3 , and to return the SMT template from the lifting conveyor line 3 to the shelf 2 .

[0068] The lifting conveyor line 3 is used to transport the SMT template to the first position so that processing equipment such as cutting equipment can cut the SMT template; and is used to transport the SMT template to the second position so that the processed SMT template can be returned to the shelf 2.

[0069] The positioning mechanism 5 is used to guide the SMT template located on the lifting conveyor line 3 .

[0070] This embodiment is described in conjunction with the control method of the SMT template automatic loading and unloading equipment of this embodiment.

[0071] In this embodiment, each SMT template, i.e., steel mesh, is placed at a different position on the shelf 2. The lifting frame 1 raises the lifting conveyor line 3 and the material picking mechanism 4 to the specified position of the shelf 2. The material picking mechanism 4 takes out the SMT template located at the specified position on the shelf 2 and places it on the lifting conveyor line 3. The lifting frame 1 lowers the lifting conveyor line 3 and the material picking mechanism 4 to a specified position, such as the bottom of the shelf 2 or below the shelf 2. The lifting conveyor line 3 transports the SMT template to a first position, such as the inside of the cutting device, and the SMT template is cut by the cutting device. After the cutting is completed, the material picking mechanism 4 takes out the SMT template from the cutting device and places it on the lifting conveyor line 3. The lifting frame 1 then raises the lifting conveyor line 3 and the material picking mechanism 4 back to the specified position on the shelf 2. The lifting conveyor line 3 transports the SMT template to a second position, such as a position close to the shelf 2, and the material picking mechanism 4 returns the SMT template to its original position on the shelf 2. In this way, each SMT template on shelf 2 can be automatically placed into the processing equipment for processing, and the processed SMT template can be taken out of the processing equipment and returned to shelf 2, which can ensure the accuracy of loading and unloading and save time, thereby improving efficiency and saving costs.
