The top of the limiting strip 206 has 25 "V"-shaped limiting grooves 207, and there is a corresponding limiting groove 207 between any two adjacent support rods 203. When the plate is inserted into the plate slot 208, the bottom of the plate is inserted into the limiting groove 207.

[0020] The lower part of the frame 1 is equipped with a belt conveyor mechanism 3 for conveying inserts with plates, a belt conveyor mechanism 5 for conveying empty inserts, and an insert translation mechanism 4 for moving the empty inserts 2 between the belt conveyor mechanism 3 and the belt conveyor mechanism 5.

[0021] The belt conveyor mechanism 3 includes two belt conveyors 9 connected in series.

[0022] The insert frame translation mechanism 4 includes two sets of linear guides 401, a set of synchronous belt linear modules 402, and a belt conveyor 9.

[0023] The belt conveyor mechanism 25 includes a belt conveyor 9.

[0024] The belt conveyor 9 includes two symmetrical longitudinal beams, multiple crossbeams, a motor mounting plate, a servo motor, a drive shaft, a driven shaft, and two annular conveyor belts. The two ends of each crossbeam are connected to the bottom ends of the two longitudinal beams. The motor mounting plate is mounted on the outside of one of the longitudinal beams. The servo motor is mounted on the motor mounting plate. The drive shaft is rotatably mounted on one end of the longitudinal beam near the servo motor. The drive shaft and the power output shaft of the servo motor are connected via a synchronous belt drive mechanism. The driven shaft is rotatably mounted on... Mounted on the longitudinal beam 1 at the end furthest from the servo motor 1, two active conveyor pulleys 1 are mounted on the active shaft 1, and two passive conveyor pulleys 1 are mounted on the driven shaft 1. The conveyor belt is tensioned by the active and passive conveyor pulleys 1 located on the same straight line. Multiple evenly distributed support rollers are mounted on the inner side of each longitudinal beam 1, with the apex of each support roller at the same horizontal height as the apex of the active and passive conveyor pulleys 1, providing support for the upper part of the conveyor belt. A guide plate is mounted at the top of each longitudinal beam 1, guiding the insert frame 2. The insert frame 2 is placed on the two conveyor belts. The servo motor 1 drives the active shaft to rotate via a synchronous belt drive mechanism, thereby causing the two conveyor belts to rotate and move the insert frame 2, thus realizing the conveying of the insert frame.

[0025] The top of the frame 1 is equipped with a flipping mechanism 6 that switches the plate between a vertical and a horizontal state, and two sets of roller conveying mechanisms 7 connected in series for conveying the plate. One set of roller conveying mechanisms 7 has an intersection area with the flipping mechanism 6 in the horizontal state. When the flipping mechanism 6 is in the horizontal state, the plate is driven by the roller conveying mechanism 7 to move in the plate conveying space 608 of the flipping mechanism 6.

[0026] The flipping mechanism 6 includes two sets of symmetrical bearings 601, a rotating shaft 602, two symmetrical L-shaped mounting plates 603, a transmission plate 604, and a telescopic cylinder 605. The telescopic cylinder 605 and the two sets of bearings 601 are respectively mounted on the frame 1. The two ends of the rotating shaft 602 are respectively fitted into the inner rings of the two sets of bearings 601. The two L-shaped mounting plates 603 are respectively mounted on the rotating shaft 602, and the L-shaped mounting plates 603 are connected to the rotating shaft 602 by a key so that the L-shaped mounting plates 603 rotate with the rotating shaft 602. The head of the transmission plate 604 is connected to the outer side of one of the L-shaped mounting plates 603 by screws. Next, a hinge block 606 is fixed to the end of the piston rod of the telescopic cylinder 605, and the tail of the transmission plate 604 is hinged to the hinge block 606 through a hinge shaft; two sets of parallel limiting roller groups 607 are installed between the two L-shaped mounting plates 603, and a flat plate conveying space 608 is formed between the two sets of limiting roller groups 607. The top of the roller conveying mechanism 7, which has an intersection area with the horizontal flipping mechanism 8, extends into the plate conveying space; the limiting roller group 607 includes multiple parallel roller shafts 6071 located on the same plane, and multiple limiting rollers 6072 are installed on each roller shaft 6071.

[0027] When telescopic cylinder 605 extends, it rotates shaft 602 through hinge block 606 and transmission plate 604, causing L-shaped mounting plate 603 and two sets of limiting rollers 607 to flip to a horizontal state; when telescopic cylinder 605 retracts, it rotates shaft 602 in the opposite direction through hinge block 606 and transmission plate 604, causing L-shaped mounting plate 603 and two sets of limiting rollers 607 to flip to a vertical state.

[0028] A bracket 609 is installed in the middle of the rotating shaft 602. The bracket 609 is clamped on the rotating shaft 602, causing the bracket 609 to rotate together with the rotating shaft 602. A telescopic cylinder 610 is installed on the bracket 609. The piston rod of the telescopic cylinder 610 moves in a direction perpendicular to the plane of the plate conveying space 608. A hook mounting plate 611 is installed at the end of the piston rod of the telescopic cylinder 610. Two L-shaped plate hooks 612 are screwed onto the side of the hook mounting plate 611 away from the plate conveying space 608. When it is necessary to support the plate 100, the telescopic cylinder 610 extends to support the plate hooks 612; when it is necessary to release the plate 100, the telescopic cylinder 610 retracts to separate the plate hooks 612 from the plate 100.

[0029] When loading, the hook of the plate support hook 612 should face the limiting roller group 607; when unloading, the hook of the plate support hook 612 should face the side away from the limiting roller group 607.

[0030] A roller shaft 613 is installed on the side of the bracket 609 near the limiting roller 6072. Multiple evenly distributed guide rollers 614 are fitted on the roller shaft 613. Two symmetrical roller shafts 615 are installed on the side of the bracket 609 away from the limiting roller 6072. Each roller shaft 615 is fitted with a guide roller 616. The guide rollers 614 and 616 are used to provide guidance and support when loading and unloading the plate, to prevent the plate 100 from sliding and rubbing against the bracket 609, and to avoid scratching the surface of the plate 100.

[0031] The roller conveyor mechanism 7 includes two symmetrical longitudinal beams, multiple parallel and evenly distributed synchronous shafts, and a servo motor. The two ends of each synchronous shaft are rotatably mounted on the two longitudinal beams. Each synchronous shaft is fitted with multiple rollers. The servo motor is located on the lower end face of one of the longitudinal beams. A linkage wheel is mounted on the power output shaft of the servo motor. A synchronous wheel is mounted on the end of each synchronous shaft closest to the servo motor. The linkage wheel and the synchronous wheel are connected for synchronous rotation via a belt. Multiple pressure rollers are mounted on the longitudinal beams, abutting against the top of the belt. Two synchronous wheels are located between adjacent pressure rollers. Multiple evenly distributed conveyor rollers are fitted in the middle of each synchronous shaft. The servo motor drives the synchronous shaft to rotate through the linkage wheel, belt, and synchronous wheels, thereby rotating the rollers on the synchronous shaft and achieving plate conveying.

[0032] A vertical conveying mechanism 8 for transporting plates in the vertical direction is installed on the frame 1 between the belt conveyor mechanism 3 and the flipping mechanism 6.

[0033] The vertical conveying mechanism 8 includes two symmetrical vertical plates 801, a servo motor 802, a drive shaft 803, and two synchronous belts 804. The bottom of the vertical plates 801 is mounted on the frame 1. A motor frame 805 is mounted on one side of one of the vertical plates 801, and the servo motor 802 is mounted on the motor frame 805. The drive shaft 803 is rotatably mounted between the two vertical plates 801 and is located directly below the rotating shaft 602. The power output shaft of the servo motor 802 is connected to the drive shaft 803 via a coupling. Two parallel synchronous pulleys 806 are keyed to the drive shaft 803. Two parallel synchronous pulleys 807 are fitted on the rotating shaft 602. The synchronous belts 804 are connected to the synchronous pulleys 806 and the synchronous belts 807 located in the same vertical direction. The pulleys 807 mesh with each other; at least one set of timing belt hooks 808 are installed on each timing belt 804. The timing belt hooks 808 include a plate support block 8081, a mounting clamping plate 8082, a limiting PP tube 8083, and a half-threaded bolt 8084. The plate support block 8081 and the mounting clamping plate 8082 are connected by screws to clamp a part of the timing belt 804 between the plate support block 8081 and the mounting clamping plate 8082. The top of the plate support block 8081 is provided with two mounting protrusions 80811. The tail of the half-threaded bolt 8084 passes through a round hole on one mounting protrusion 80811 and is screwed into a screw hole on the other mounting protrusion 80811. The limiting PP tube 8083 is sleeved on the half-threaded bolt 8084 located between the two mounting protrusions 80811.

[0034] The servo motor drives the second drive shaft 803 to rotate, and through the cooperation of the first synchronous pulley 806, the second synchronous pulley 807, and the first synchronous belt 804, the synchronous belt hook 808 moves upward or downward in the vertical direction, and the plate 100 is supported by the synchronous belt hook 808 to move upward or downward.

[0035] A connecting plate 8011 perpendicular to the side of the vertical plate 801 is installed on the inner side of each vertical plate 801. A long strip mounting plate 8012 parallel to the vertical plate is installed on the side of the connecting plate 8011 away from the vertical plate 801. Multiple roller shafts 8013 are installed on the vertical plate 801 and the long strip mounting plate 8012 respectively. A guide roller 8014 is fitted on each roller shaft 8013.

[0036] Feeding process: The insert holder containing the plate is placed on the belt conveyor 3 and conveyed by the belt conveyor 3 to the vertical conveyor 8. The two sets of limiting rollers 607 of the flipping mechanism 6 are in a vertical state. The synchronous belt hooks 808 of the vertical conveying mechanism 8 support the plate 100 and convey it upward until the bottom of the plate 100 is higher than the plate hooks 612 of the flipping mechanism. The upper part of the plate 100 enters the plate conveying space 608 between the two sets of limiting rollers 607. The extension of the telescopic cylinder causes the plate support hook 612 to extend below the plate 100. At this time, the synchronous belt hook 808 moves downward and separates from the plate 100, and the plate 100 is supported by the plate support hook 612. When the telescopic cylinder extends, the flipping mechanism 6 flips to the limit roller group 607 in a horizontal state, and the plate 100 is transported to the next plate processing step by the roller conveying mechanism 7. When all the plates 100 on a set of insert frames 2 have been loaded, the empty insert frames 2 are conveyed to the belt conveyor 9 of the insert frame translation mechanism 4. Then, the belt conveyor 9 of the insert frame translation mechanism 4 is driven by the synchronous belt linear module 402 to move from one side of the belt conveyor mechanism 3 to the other side of the belt conveyor mechanism 5. Then, the belt conveyor 9 of the insert frame translation mechanism 4 conveys the empty insert frames to the belt conveyor mechanism 5.

[0037] Material feeding process: The empty insert 2 is placed on the second belt conveyor 5, and the second belt conveyor 5 transports the empty insert to the belt conveyor 9 of the insert translation mechanism 4. Then, the synchronous belt linear module 402 drives the belt conveyor 9 of the insert translation mechanism 4 to move from one side of the second belt conveyor 5 to one side of the first belt conveyor 3. Then, the belt conveyor 9 of the insert translation mechanism 4 transports the empty insert to the first belt conveyor 3. The two sets of limiting rollers 607 of the flipping mechanism 6 are in a horizontal state, and the telescopic cylinder 2 is in an extended state. The roller conveying mechanism 7 conveys the plate to the plate conveying space 608 between the two sets of limiting rollers 607 until the plate contacts the plate hook 612. When the telescopic cylinder extends, the flipping mechanism 6 flips until the two sets of limit rollers 607 are in a vertical state. The synchronous belt hook 808 moves upward until the synchronous belt hook 808 lifts the plate 100 upward. At this time, the telescopic cylinder retracts, causing the plate hook to separate from the plate 100. The synchronous belt hook 808 moves downward until the bottom of the plate falls into the limiting groove 207. After a set of inserters 2 completes the plate insertion task, the belt conveyor 3 transports the inserters 2 with the plate 100 inserted in a direction away from the vertical conveyor 8.
