Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hot pressing and forming equipment, in particular to a loading and unloading mechanism for sheets. Background Art
[0002] The back covers and / or screens of some electronic products such as mobile phones and tablets adopt curved panel designs, such as glass curved panels, glass fiber curved panels, plastic curved panels, etc. The specific forming method is to form a curved panel with a curved surface by heating, pressing and then cooling the cut sheets.
[0003] During the production process, it is necessary to put the sheets to be processed into the opened mold, and it is also necessary to take out the formed curved panels in the opened mold. On the one hand, the loading and unloading need to be quickly and sequentially operated at the same station. On the other hand, the loading and unloading space is small after the mold is opened. Therefore, it is not suitable to use traditional loading and unloading devices for loading and unloading. At present, most of them are manually operated, which not only has low production efficiency, but also the inaccurate placement position of the sheet materials will cause fluctuations in the subsequent forming quality, so it is necessary to be improved. Summary of the Utility Model

[0022] One working mode of the manipulator in this embodiment is as follows: the linear device 4 drives the flipping and picking device 6 to move to the storage device 2. After lifting by the lifting device 5, the suction cups 632 on the first side mounting plate 631 adsorb and take out the sheet material, and after flipping 180°, it is transferred to the middle of the opened mold. Then, the suction cups 632 on the second side mounting plate 631 adsorb and take out the curved panel in the mold and flip it 180°, so that the sheet material is placed downward into the mold. Finally, the linear device 4 drives the flipping and picking device 6 to move to the discharging device 3, and after flipping 180°, the curved panel is put down, thus completing a picking and placing cycle. In other embodiments, the sequence of actions can be adjusted and changed, and the picking and placing can still be achieved.
[0023] A preferred solution is that the linear device 4 in this embodiment includes a substrate 41 arranged in a linear direction, a second servo motor 42 mounted on the substrate 41, a second synchronous belt 43 driven by the second servo motor 42, a mounting seat 44 driven by the second synchronous belt 43, and a second guide rail pair 45 for slidably mounting the mounting seat 44 on the substrate 41. In other embodiments, other conventional structures can also be used to achieve linear movement. For example, the synchronous belt can be replaced with a lead screw pair, which is a conventional technical means in this field.
[0024] A preferred solution is that the lifting device 5 in this embodiment includes a second cylinder 51 mounted on the mounting seat 44, a vertical plate 52 driven by the second cylinder 51 to lift, and a third guide rail pair 53 for slidably mounting the vertical plate 52 on the mounting seat 44. The flipping and picking device 6 is mounted on the vertical plate 52. The second cylinder 51 drives the flipping and picking device 6 to lift integrally through the vertical plate 52 to approach the sheet material or the curved panel, or to reset.
[0025] A preferred solution is that the rotation drive assembly 62 in this embodiment includes a gear 621 concentrically fixed on the rotating rod 61, a rack 622 meshing with the gear 621, a first cylinder 623 driving the linear reciprocating movement of the rack 622, and a slide rail installed between the rack 622 and the vertical plate 52 for stabilizing the rack 622. The rotating rod 61 is rotatably mounted on a support 521 extending from the vertical plate 52 through a bearing. The first cylinder 623 drives the rack 622 to reciprocate vertically, and drives the rotating rod 61 to perform a reciprocating rotation of 180° through the meshing gear 621.
[0026] A preferred solution is that the storage device 2 in this embodiment includes a vertical standing plate 21, a loading plate 22 for carrying stacked sheet materials, and a feeding drive device 23 for driving the loading plate 22 to lift along the front of the standing plate 21; the feeding drive device 23 includes a first servo motor 231, a first synchronous belt 232 driven by the first servo motor 231, a slider 233 driven by the first synchronous belt 232, and a guide rail 234 vertically arranged for slidably assembling the slider 233; the feeding drive device 23 is arranged on the back of the standing plate 21, and a first through groove 211 is formed in the standing plate 21 along the lifting direction, and a part of the loading plate 22 passes through the first through groove 211 and is fixed to the slider 233. The loading plate 22 is used to carry stacked sheet materials to be processed, and one side of each sheet material is aligned by the front of the standing plate 21. The first servo motor 231 drives the loading plate 22 to rise gradually, that is, every time a sheet is taken away, it rises by a height equivalent to the thickness of the sheet material; the feeding drive device 23 is arranged on the back of the standing plate 21 without affecting the placement of the sheet materials on the front.
[0027] In a preferred solution, a bottom plate 24 parallel to the lower part of the material loading plate 22 is further fixedly arranged on the front surface of the vertical plate 21 in this embodiment. The bottom plate 24 is provided with a second through groove 241 along the X-axis and the Y-axis. A limiting rod 25 for abutting against the side edge of the sheet is vertically installed in the second through groove 241. The bottom end of the limiting rod 25 is installed on the bottom plate 24 through a first guide rail pair 26 arranged along the direction of the second through groove 241. The position of the limiting rod 25 can be adjusted manually along the first guide rail pair 26 so that it abuts against one side edge of each sheet for limiting; after manual adjustment, the position can be locked and fixed, and only the position of the limiting rod 25 needs to be adjusted here when processing sheets of different sizes.
[0028] In a preferred solution, the discharging device 3 is a conveyor belt, and the head end of the conveyor belt and the storage device 2 are respectively located at both ends on the same side of the linear device 4.
[0029] The above does not impose any limitation on the technical scope of the present invention.
