For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figure 1 As shown, an embodiment of the utility model provides a sheet loading device, including a loading platform 1, the loading platform 1 is provided with a loading trough 2, and the loading trough 2 is provided with a plurality of and arranged in a matrix, so as to load multiple groups of sheets at the same time, and facilitate a material transfer robot to transfer multiple groups of sheets at one time, thereby improving the operation efficiency of the production line.

[0025] At the same time Figure 2 As shown, the loading chute 2 is composed of a bottom plate 3, a longitudinal plate 4 and a transverse plate 5. The bottom plate 3 is arranged on the upper surface of the loading platform 1. A plurality of mounting holes are provided on the bottom plate 3. A plurality of mounting holes are also provided on the longitudinal plate 4 and the transverse plate 5. The corresponding positions are connected by corner connectors 6 so that the loading chute 2 can be easily assembled and disassembled, and can be flexibly arranged to meet the loading requirements of different groups.

[0026] As a further improvement, in the present embodiment, a rotating component 7 is further provided between the base plate 3 and the loading platform 1. The rotating component 7 includes a rotating drive motor, a rotating bearing seat and a rotating connecting shaft. The rotating bearing seat is fixedly connected to the loading platform 1. The rotating connecting shaft is passed through the rotating bearing seat, one end of which is connected to the loading platform 1, and the other end is connected to the rotating drive motor, so that the loading trough 2 is controlled by the rotating drive motor to rotate 180 degrees as a whole each time, and the loading trough 2 on one side is used to load the sheet (by manual or automated equipment), and the sheet in the loading trough 2 on the other side is taken out by the material transfer robot.

[0027] In this embodiment, the material transfer robot includes a mechanical arm 8 and a material taking component 9 located at the execution end of the mechanical arm 8. The mechanical arm 8 has multiple degrees of freedom of movement to control the material taking component 9 to take materials from the loading trough 2. Figure 3 As shown, the material picking assembly 9 includes a material picking mounting plate 10, a material picking connecting rod 11 detachably connected to the material picking mounting plate 10, and a material picking adsorption portion detachably connected to the material picking connecting rod 11. The material picking adsorption portion adsorbs the sheet through negative pressure. For each sheet, at least one pair of material picking adsorption portions is provided to adsorb the two ends of the sheet respectively, so that the sheet, especially the sheet with a certain flexibility, can be adsorbed and transferred in the original posture to avoid irregular folding when entering the subsequent workstation.

[0028] In this embodiment, the material picking adsorption part includes an adsorption head 12 and an adsorption connection buckle 13. The adsorption connection buckle 13 is connected to the adsorption head 12 and is buckled on the material picking connecting rod 11 to fix the adsorption head 12. Figure 4 As shown, one or more adsorption holes 14 are provided at the bottom of the adsorption head 12, and multiple adsorption holes 14 are used as a preferred embodiment so that the negative pressure can be more evenly transmitted to the surface of the sheet material to avoid damage to the flexible sheet material. An air pipe joint 15 is provided on the side wall of the adsorption head 12, and a negative pressure device is connected through the air pipe joint 15 to generate negative pressure, thereby completing negative pressure adsorption of the sheet material.

[0029] As a preferred embodiment, in this embodiment, a fixed column 16 is provided at the bottom end of the adsorption connection buckle 13, and a movable column 17 is provided at the top end of the adsorption head 12. The top end of the movable column 17 is inserted into the central hole of the fixed column 16, and is movably connected to the fixed column 16, and is provided with a spring 18 to form an elastic and movable connection. In addition, a limiting groove is provided on the side wall of the movable column 17, and a limiting pin is provided on the adsorption connection buckle 13. The limiting pin is used to ensure the movement range of the movable column 17, and the spring 18 will not be over-compressed, and the movable column 17 will not be completely pulled out of the fixed column 16. In this way, the adsorption head 12 and the adsorption connection buckle 13 are elastically and movably connected. Therefore, in the process of the mechanical arm 8 controlling the material collection component 9 to move downward to adsorb and collect materials, the bottom end of the adsorption head 12 will not have a hard collision with the sheet material, but rely on the spring 18 to elastically buffer and remove the impact force, which has a better protection effect for brittle sheets.

[0030] In this embodiment, the adsorption connection buckle 13 is locked and loosened by bolts, and can be adjusted and fixed at different positions of the material-retrieving connecting rod 11 to meet the operating requirements of sheets of different sizes.

[0031] Using the sheet loading device provided in this embodiment, manual or automated equipment loads the sheets into each loading trough 2 on the first side of the loading platform 1, with the sheets in each loading trough 2 being a stack. The rotating component 7 is then driven to rotate 180 degrees, so that the sheets rotate to the second side of the loading platform 1 along with the loading trough 2. The material transfer robot simultaneously retrieves and transfers materials to each loading trough 2. At this time, the empty loading trough 2 rotated to the first side of the loading platform 1 can be loaded synchronously, saving operation time and improving operation efficiency.

[0032] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
