The first slide 4012 can move between the assembly mechanism and the storage mechanism of the locking device to form a relatively long structure. In the present embodiment, a driving motor 4011 is provided at the end of the horizontal slide 401. At the same time, a screw is rotatably installed in the horizontal slide. The axis of the screw is parallel to the length direction of the horizontal slide 401. The output end of the driving motor 4011 is connected to the screw for driving the screw to rotate. The first slide 4012 is threadedly connected to the screw. Specifically, a nut is fixed at the lower end of the first slide 4012. The nut is threadedly connected to the screw.

In the present embodiment, the driving motor is a servo motor or a stepping motor with high rotation accuracy, and can accurately control the horizontal sliding of the first slide 4012.

[0036] In order to avoid over-travel and improve safety in use, limit blocks 4013 are provided at both ends of the horizontal slide. The limit blocks 4013 are elastic and are used to physically limit the first slide 4012, thereby improving its safety in use and avoiding over-travel caused by electrical reasons.

[0037] A grabbing station, a flipping station and a unloading station are sequentially arranged on the movement path of the first slide 4012, wherein the grabbing station is used to grab the material tray assembled on the assembly mechanism, the flipping station is used to flip the material tray, and after passing through this station, it will not collide with other parts of the equipment (especially the assembly mechanism) when flipping, thereby improving the safety and stability of material transfer, and the unloading station is used to dock with the manipulator of the storage mechanism; detection sensors 4014 are provided on the above-mentioned grabbing station, flipping station and unloading station for detecting the station and realizing corresponding actions of the corresponding station. At the same time, a trigger part 4015 is provided on the first slide 4012, and the trigger part 4015 can trigger the detection sensor 4014 to realize position detection and then send a signal to facilitate the realization of different actions. In this embodiment, the trigger part is a sheet structure, which is fixed at the bottom of the first slide, and the end is bent downward by 90 degrees to form a trigger part.

[0038] A first mounting seat 402 is fixed on the first sliding seat 4012 , and serves as a mounting carrier to facilitate the installation of other components. In this embodiment, the first mounting seat 402 is a horizontally arranged plate structure.

[0039] The sliding assembly is arranged on the upper surface of the first mounting seat 402, and includes a slider 4031 and a first cylinder 403 for driving the slider 4031 to slide horizontally. The sliding direction of the slider 4031 is perpendicular to the sliding direction of the first slide seat 4012. In this embodiment, the first cylinder is horizontally fixed on the upper surface of the first mounting seat, and the slider 4031 is slidably fitted on the upper surface of the first cylinder 403, and its sliding direction is perpendicular to the sliding direction of the first slide seat. A connecting plate 4032 is provided at the output end of the first cylinder 403, and the connecting plate is rigidly connected to the end of the slider 4031, thereby realizing the connection between the first cylinder and the slider. The above-mentioned connecting plate and the slider form an L-shaped structure.

[0040] A second mounting seat 404 is fixed on the second sliding block 4031 . In this embodiment, the second mounting seat 404 is a vertically arranged plate-shaped structure.

[0041] The first rotating assembly is arranged on the second mounting seat 404, including a first rotating cylinder 405 and a first rotating seat 4051 fixed at the output end of the first rotating cylinder 405. The first rotating cylinder 405 is fixed to the side wall of the second mounting seat 404, and the rotation axis of the first rotating seat 4051 is parallel to the sliding direction of the first slide seat 4012. In this embodiment, the rotation angle of the first rotating seat 4051 is greater than or equal to 45 degrees. Since the material tray has a square structure, preferably, its rotation angle is 45 degrees, which can lift the material tray upward at 45 degrees, so that the top angle of the material tray is set upward and downward, which is convenient for the next storage process; the above-mentioned first rotating seat 4051 is a plate-like structure, one end of which is arc-shaped, forming a U-shaped structure.

[0042] The second rotating assembly is arranged on the first rotating seat 4051, including a second rotating cylinder 406 fixed to the side wall of the first rotating seat and a second rotating seat fixed to the output end of the second rotating cylinder 406. The rotation axis of the second rotating seat is perpendicular to the rotation axis of the first rotating seat 4051. The rotation angle of the second rotating seat is 90 degrees, which can rotate the horizontal material tray to a vertical state.

[0043] The clamping assembly is arranged on the second rotating seat, including a clamping cylinder 407 and a clamping claw 4071 arranged at the output end of the clamping cylinder 407. In this embodiment, the clamping cylinder is a finger cylinder, and there are two clamping claws 4071, which are respectively arranged on the two output shafts of the clamping cylinder, which can realize clamping or loosening. The clamping or loosening direction of the clamping claw 4071 is perpendicular to the rotation axis of the second rotating seat, thereby realizing the movement (transportation) of the material tray. A clamping surface 4071a is provided on the inner side of the clamping claw 4071. The clamping surface 4071a is a plane, which can fit the surface of the material tray. Since there is a flipping action during the transportation process, in order to improve the stability and reliability of clamping and avoid deviation during the movement, an anti-slip pattern or an anti-slip layer is provided on the clamping surface 4071a. The anti-slip pattern is a plurality of protrusions or grooves. The anti-slip layer can be rubber or silicone, which has a certain elasticity and friction, increases the friction with the surface of the material tray, and thus improves the reliability and stability of grasping.

[0044] In order to improve the operation accuracy and reliability and realize automatic operation, in this embodiment, limit switches are provided at the two limit positions of the first slide 4012 or the slider 4031. The limit switch on the slider 4031 is described below; a switch mounting seat 4033 is provided on the first mounting seat, and a limit switch 4034 is installed on the switch mounting seat. At the same time, a contact block 4035 is provided on the side wall of the slider 4031. The contact block can trigger the limit switch 4034 to detect the movement state of the slider. Since the movement stroke of the slider is relatively short, the limit switch 304 is set on both sides of the slider in this application.

[0045] The following is a brief description of the material transfer (handling) process of the mechanism:

[0046] In the initial state, the slider 4031 moves backward and resets, that is, it moves in the direction away from the locking mechanism, and the first rotating seat 4051 rotates to a horizontal position, that is, the second rotating cylinder 406 is in a horizontal state. At the same time, the clamp is in a horizontal position, that is, its clamping surface 4071a is in a horizontal state. At the same time, the first slide seat 4012 slides to the material grabbing station.

[0047] During operation, the slider moves forward, that is, moves in the direction close to the locking mechanism, so that the material tray on the locking device (discharging station) is located between the two clamping surfaces of the clamping claws, and the clamping cylinder drives the clamping claws to clamp the material tray, and then the first rotating seat 4051 rotates upward to move the material tray out of the material hole of the locking mechanism. In this embodiment, its upward rotation angle is 45 degrees, and the slider moves backward to make it free from the interference of other components of the locking mechanism to avoid collision; after the slider completes the backward movement, the first slide moves toward the material bin, and when passing the flipping station, the sensor is triggered and an induction signal is sent to make the second rotating cylinder rotate 90 degrees, even if the clamping claws rotate 90 degrees, so that the material tray is in a vertical state, and at the same time, the angle of the material tray is facing up and down; the first slide continues to slide until it moves to the unloading station and stays for a certain time, which can be set or determined by other sensors and other components, and the material picking robot on the storage mechanism takes away the material tray in a 45-degree and vertical state, and then resets it and performs the next material moving action.

[0048] The material tray discharging and handling mechanism of the utility model adopts a driving motor structure, which can realize long-stroke movement with high movement accuracy, and can move between different workstations to realize material transfer; the multi-cylinder structure is set, the structure is compact, the installation space is small, it is conducive to miniaturization, the response is fast, and it can realize material picking and two-way rotation, which is convenient for storage and feeding of the downward moving process; the anti-skid pattern or anti-skid layer is set on the clamping claw, which can increase the friction with the material tray, improve the reliability and stability of grasping, and avoid deflection or falling during movement; the multi-sensor setting can realize the corresponding workstation detection during the sliding process and perform corresponding actions, with high accuracy and automation; the material tray discharging and handling mechanism of the utility model has a compact structure, can realize fast material grabbing, material transfer and material transfer, so as to move the material tray of the locking station to the storage station, with high operating efficiency and accuracy, and is convenient for the fully automated operation of the locking mechanism.
