A first-level loading plate 300, a second-level loading plate 301, and a third-level loading plate 302 are fixedly installed on the inner wall of the lifting loading box 201. A lifting ladder 303 is slidably installed on the inner wall of the lifting loading box 201. The lifting ladder 303 has a connection with the second-level loading plate 301 and the third-level loading plate 302. The loading plate 302 and the lifting and loading ladder 303 are adapted to the protrusions, and a U-shaped fixed mounting frame 400 is fixedly installed on the inner wall of the lifting and loading box 201, and an L-shaped lifting plate 401 is slidably installed on the U-shaped fixed mounting frame 400, and a placement rack 402 is fixedly installed on the L-shaped lifting plate 401, and the placement rack 402 is adapted to the lifting and loading ladder 303.

[0023] In an optional embodiment: a lifting motor 500 is fixedly installed on the inner wall of the lifting loading box 201, a reduction gear box 501 is installed on the lifting motor 500, an output shaft 502 is installed on the reduction gear box 501, a rotating rod 503 is fixedly installed on the output shaft 502, one end of a driving rod 504 is rotatably installed on the rotating rod 503, the other end of the driving rod 504 is rotatably installed on the lifting ladder 303, and both ends of the driving rod 504 are rotatably installed with rotating shafts 505, and the two rotating shafts 505 are respectively fixedly installed on the lifting ladder 303 and the rotating rod 503.

[0024] It should be noted that the output of the lifting motor 500 is decelerated through the output shaft 502 and output through the rotating rod 503. The rotating rotating rod 503 drives the driving rod 504 to move through the rotating shaft 505, and the movable driving rod 504 drives the lifting ladder 303 to rise and fall on the inner wall of the lifting loading box 201 through another rotating shaft 505.

[0025] In an optional embodiment: two fixed mounting frames 506 are fixedly installed on the inner wall of the lifting loading box 201, two fixed rods 507 are fixedly installed between the two fixed mounting frames 506, and sliding mounting sleeves 508 are slidably installed on the two fixed rods 507. Two pairs of sliding mounting sleeves 508 are respectively fixedly installed on both sides of the lifting ladder 303.

[0026] It should be noted that the position of the lifting ladder 303 is repeatedly raised and lowered, so that the workpiece 102 is installed on the trajectory of the first-level loading plate 300, the second-level loading plate 301, and the third-level loading plate 302. The movable lifting ladder 303 is restricted by the fixed rod 507 through the sliding mounting sleeve 508 and moves stably within a fixed range.

[0028] It should be noted that the movable L-shaped lifting plate 401 is restricted by the connecting rod 404 through the connecting sleeve 403 and rises stably within a fixed range.

[0029] In an optional embodiment: a lifting cylinder 405 is fixedly installed on the bottom side of the U-shaped fixed mounting frame 400, an L-shaped mounting plate 406 is fixedly installed on the output end of the lifting cylinder 405, and the L-shaped mounting plate 406 is fixedly installed on the L-shaped lifting plate 401.

[0030] It should be noted that the output end of the lifting cylinder 405 drives the L-shaped lifting plate 401 and the placement rack 402 to move to their respective positions via the L-shaped mounting plate 406 .

[0031] In an optional embodiment: a driving block 600 is slidingly mounted on the U-shaped fixed mounting frame 400, an extension rod 601 is fixedly mounted on each of the two driving blocks 600, a positioning rod 602 is fixedly mounted on each of the two extension rods 601, and the two positioning rods 602 are respectively adapted to the two ends of the workpiece 102, an output end of a driving air pump 603 is fixedly mounted on one of the driving blocks 600, the driving air pump 603 is fixedly mounted on the U-shaped fixed mounting frame 400, a rotating gear 604 is rotatably mounted on the U-shaped fixed mounting frame 400, a transmission rack 605 is fixedly mounted on each of the two driving blocks 600, and the two transmission racks 605 are engaged with the rotating gear 604.

[0032] It should be noted that the driving air pump 603 drives the driving block 600 to slide on the U-shaped fixed mounting frame 400, and drives the extension rod 601 and the positioning rod 602 to move, so that the two positioning rods 602 position their positions on both sides of the workpiece 102, ensuring that the workpiece 102 has a fixed position on the placement frame 402. Then, the movement of the driving block 600 will also drive the transmission rack 605 to drive the rotating gear 604 to rotate, thereby realizing the synchronous movement of the driving blocks 600 on both sides.

[0033] Working principle of this utility model:

[0034] When the device is used, the movable door panel 103 is opened to a suitable gap so that the workpiece 102 enters the lifting loading box 201 from the bottom side of the movable door panel 103, and the workpiece 102 falls on the first-level loading plate 300. The position of the lifting ladder 303 is repeatedly raised and lowered, so that the workpiece 102 is installed on the trajectory of the first-level loading plate 300, the second-level loading plate 301, and the third-level loading plate 302. The movable lifting ladder 303 is restricted by the fixed rod 507 through the sliding mounting sleeve 508 and moves stably within a fixed range. Then the lifting motor 500 is started, and the output of the lifting motor 500 is decelerated through the output shaft 502 and output through the rotating rod 503. The rotating rotating rod 503 drives the driving rod 504 to move through the rotating shaft 505, and the movable driving rod 504 drives the lifting ladder 303 to move up and down on the inner wall of the lifting loading box 201 through another rotating shaft 505. When the workpiece 102 moves to the position of the third-level loading plate 302, , and with the lifting movement again, it will move to the placement rack 402, and at this time, the driving air pump 603 is started, and the driving air pump 603 drives the driving block 600 to slide on the U-shaped fixed mounting rack 400, and drives the extension rod 601 and the positioning rod 602 to move, so that the two positioning rods 602 are positioned on both sides of the workpiece 102, ensuring that the workpiece 102 has a fixed position on the placement rack 402. Then, the movement of the driving block 600 will also drive the transmission rack 605 to drive the rotating gear 604 to rotate, thereby realizing the synchronous movement of the driving blocks 600 on both sides, and starting the lifting cylinder 405. The output end of the lifting cylinder 405 drives the L-shaped lifting plate 401 and the placement rack 402 to move to a movable position through the L-shaped mounting plate 406. The movable L-shaped lifting plate 401 is restricted by the connecting rod 404 through the connecting sleeve 403 and rises stably within a fixed range. At this time, the handling robot arm 202 can be used to remove the workpiece 102 on the placement rack 402.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
