[0004] Due to the lack of automated loading, additional manual support is required for loading the production line during the processing, which not only reduces the degree of automation in the loading process of the production line, but also increases labor costs. Utility Model Content

[0005] In order to overcome the problems existing in the loading link of the laser cutting production workstation in the prior art and improve the degree of automation and efficiency of the production line, the present application provides an automatic loading device for display screens.

[0006] The automatic display screen feeding device provided in this application adopts the following technical solution:

[0007] An automatic loading device for a display screen includes a frame, on which a full box loading device, a conveying device, a product transferring device, an empty box transferring device, and an empty box unloading device are sequentially arranged. The full box loading device is used to transfer a plurality of stacked blister boxes, each blister box containing a plurality of products; the conveying device is used to simultaneously transfer a plurality of products in the topmost blister box to a correction device, the correction device is used to correct the position of the products, the product transferring device is used to transfer a plurality of products to be processed to the processing equipment; the empty box transferring device is used to sequentially transfer the empty boxes to the empty box unloading device, and the empty box unloading device simultaneously unloads a plurality of empty blister boxes.

[0008] By adopting the above technical solution, first, a full box loading device is used to load a plurality of stacked blister boxes (each blister box contains a plurality of products). Then, a conveying device takes out a plurality of products from the top layer of the stacked boxes and simultaneously transfers them to the processing equipment for processing. At the same time, an empty box unloading device transfers the empty blister boxes from which the products have been removed layer by layer to an empty box conveying device, which unloads the empty blister boxes.

[0009] Optionally, the full box loading device includes a horizontal feeding mechanism and a lifting feeding mechanism, wherein the first horizontal feeding mechanism is used to move multiple stacked blister boxes in the horizontal direction, and the lifting feeding mechanism is used to move multiple stacked blister boxes in the vertical direction.

[0010] By adopting the above technical solution, both the full box loading device and the empty box loading device include a horizontal feeding mechanism and a lifting feeding mechanism, which realizes the precise movement of the blister boxes in the horizontal and vertical directions. This not only improves the degree of automation of the loading and unloading processes, but also ensures the stability of the blister boxes during transportation, reduces errors caused by human operation, and improves the efficiency and reliability of the overall production line. Specifically, the horizontal feeding mechanism can accurately move multiple stacked blister boxes into place in the horizontal direction, while the lifting feeding mechanism can move the blister boxes layer by layer in the vertical direction, ensuring the accuracy and continuity of each step of the operation. This design significantly improves the level of automation of the production line, reduces manual intervention, thereby reducing labor costs and improving production efficiency.

[0011] Optionally, the lifting and feeding mechanism includes a lifting drive assembly and a first lifting seat, the lifting drive assembly is arranged on the frame, the lifting drive assembly is used to drive the first lifting seat to rise and fall, and the first lifting seat is used to carry the stacked blister boxes.

[0012] By adopting the above technical solution, after the horizontal feeding mechanism transports multiple stacked blister boxes to the second lifting seat and the first lifting seat, the second lifting seat and the first lifting seat are driven to rise and fall by the lifting drive assembly, so that the lifting position and speed of the blister box can be accurately controlled. When the blister box rises to an appropriate height, it is convenient for the conveying mechanism to transport the products in the blister box on the top layer to the processing equipment for processing.

[0013] Optionally, the transport device includes a first transverse movement mechanism, a lifting mechanism, a rotating mechanism and a first adsorption mechanism. The first transverse movement mechanism is arranged on the frame. The first transverse movement drive mechanism is used to drive the lifting mechanism to move in a horizontal direction. The lifting mechanism is used to drive the rotating mechanism to rotate. The rotating mechanism is used to drive multiple first adsorption mechanisms to rotate at the same time, and each first adsorption mechanism is used to adsorb products.

[0014] By adopting the above-mentioned technical solution, the coordinated use of the first transverse drive mechanism and the lifting mechanism enables the handling device to move flexibly in the horizontal and vertical directions, achieving fast and accurate product handling, and significantly improving the work efficiency of the production line. The design of the rotating mechanism allows multiple first adsorption mechanisms to rotate simultaneously, thereby transporting multiple products at a time, further improving the handling speed and production efficiency. The entire handling process is fully automated and requires no human intervention, avoiding errors and delays caused by human factors and ensuring the continuity and stability of production. The first adsorption mechanism can accurately adsorb products, avoiding possible damage during handling, ensuring the integrity of the products, and thus improving the quality of the final product.

[0015] Optionally, the product transfer device includes a transverse driving mechanism, a transverse seat, a first lifting driving mechanism, a lifting frame and a third adsorption mechanism. The transverse driving mechanism is arranged on the frame, and the transverse driving mechanism is used to drive the transverse seat to move in the horizontal direction; the first lifting driving mechanism is arranged on the transverse seat, and the first lifting driving mechanism is used to drive the lifting frame to rise and fall. The third adsorption mechanism is arranged on the lifting frame, and the third adsorption mechanism always transports the products in the blister box to the next process.

[0016] By adopting this technical solution, the traverse drive mechanism drives the traverse seat horizontally, while the first lift drive mechanism drives the lift frame vertically. This allows the third suction mechanism mounted on the lift frame to accurately transport products in blister boxes to the next process. This not only increases the degree of automation in product transfer, but also ensures stability and accuracy during the transfer process, thereby improving the overall efficiency and product quality of the production line.

[0017] Optional,

The second transverse movement mechanism is arranged on the frame. The second transverse movement mechanism is used to drive the second adsorption mechanism to move in the horizontal direction. The second adsorption mechanism is used to adsorb the empty blister boxes. It can effectively realize the automatic handling and unloading of empty blister boxes, avoid manual intervention, and improve production efficiency and the degree of automation. Specifically, the second transverse movement mechanism can accurately control the movement of the second adsorption mechanism in the horizontal direction, ensuring that each empty blister box transported can be accurately placed in the designated position, reducing errors and time waste caused by manual operation. The design of the second adsorption mechanism can effectively adsorb and stably transport empty blister boxes, ensuring the stability and reliability of the transportation process.

[0020] Optionally, a correction device is also included, which includes a base, a second lifting seat, a transverse driving mechanism, a pushing mechanism and a positioning mechanism. The base is arranged on the frame, and the second lifting seat and the first lifting seat are slidably cooperated with the base.

Specifically, the design of the base and secondary lift allows for horizontal movement, accommodating products of varying sizes. The combined use of the pusher and positioning mechanisms ensures accurate product positioning before subsequent processing, avoiding quality issues caused by misaligned positioning. This design not only improves product processing accuracy but also enhances overall production line efficiency, reducing rework and scrap caused by inaccurate product positioning.

[0037] Reference Figure 3 Specifically, the full-box loading device 2 includes a horizontal feed mechanism 21 and a lifting feed mechanism 22. The horizontal feed mechanism 21 is used to horizontally move multiple stacked blister boxes, each containing multiple products in an orderly arrangement.

During the vertical feeding process, the second lifting seat 42 will carry the stacked blister boxes and move up and down as the lifting drive assembly is driven. When it is necessary to provide products to the processing equipment, the lifting and feeding mechanism 22 will lift the topmost blister box to an appropriate height so that it can be docked with the conveying device 3.

This mechanism can utilize a motor, a pneumatic cylinder, or other suitable drive method, ensuring smooth raising and lowering of the lifting frame 54 through precise control. During the raising and lowering process, the lifting frame 54 maintains a stable posture, ensuring that products placed on it are not damaged by shaking.

This mechanism may include multiple suction cups or other suitable structures for product absorption, ensuring a secure grip without damaging the product. The third suction mechanism 55 allows products to be smoothly transferred from the transport device 3 to the product transfer device 5.
