[0022] In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. In addition, the technical features involved in the different embodiments of the utility model described below can be combined with each other as long as they do not conflict with each other.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a locking connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] like Figure 1As shown, an embodiment of the utility model provides a universal loading and unloading device suitable for a CNC cutting machine, including a gantry frame 1, which is arranged on a parallel, longitudinally arranged running track 2, and shuttles between a plate material rack 3 and a CNC cutting machine workbench 4, and is used to transport the plates on the plate material rack 3 to the CNC cutting machine workbench 4 in sequence to complete the CNC cutting operation.

[0026] At the same time Figure 2 As shown, the gantry body 1 includes a passive running part 5, an active running part 6, columns 7 arranged on the passive running part 5 and the active running part 6, and a crossbeam 8 connecting the two columns 7 (or directly connected without the column 7). Among them, the passive running part 5, the active running part 6, the columns 7 and the crossbeam 8 are an integrated structure, forming a gantry form. The passive running part 5 and the active running part 6 are both provided with rollers or other types of running mechanisms, and are respectively connected to the corresponding running tracks 2. Obviously, the active running part 6 is also provided with a driving mechanism for providing power to drive the running mechanism to move along the track, and the passive running part 5 then moves along the track, which has the functions of guiding, balancing and supporting.

[0027] In this embodiment, a lateral displacement mechanism and a vertical displacement mechanism are provided on the crossbeam 8. The lateral displacement mechanism includes a slider 9, which is slidably provided on the slide rail of the crossbeam 8, and is used to adjust the lateral position, and is driven by a screw assembly or the like. The vertical displacement mechanism is provided on the slider 9, and is used to adjust the vertical position, and can be in the form of a vertical mechanical arm 10 or a lifting platform or the like. It should be noted that the specific forms of the lateral displacement mechanism and the vertical displacement mechanism are not specifically limited in this embodiment, and those skilled in the art can flexibly select a linear displacement mechanism according to the actual arrangement.

[0028] A lifting device 11 is provided at the end of the vertical displacement mechanism, which is used to lift the plate. Figure 3 As shown, the sling 11 includes a sling main beam 12, the middle of which is connected to the vertical displacement mechanism via a rotating shaft 13, and can adjust the angle (i.e., azimuth) of the sling main beam 12 relative to the vertical axis (driven by a motor). An electromagnet 14 and a sling drum 15 are arranged on the sling main beam 12.

[0029] The electromagnet 14 is distributed on the lower surface of the main beam 12 of the sling, and is used to magnetically adsorb the ferromagnetic sheet after being powered on, so as to load and unload the ferromagnetic sheet. The sling drum 15 is wound with a sling, which is connected to a hook (or directly tied to the sheet) to lift and load the non-ferromagnetic sheet.

[0030] It should be noted that in this embodiment, the electromagnets 14 are evenly arranged along the lower surface of the main beam 12 of the hanger. After power is turned on, they generate a strong magnetic force to adsorb and fix the ferromagnetic plate. Compared with the suction cup method, it is more stable and less likely to shake during the transfer process.

[0031] It should be noted that in this embodiment, the sling drum 15 is of automatic rewinding type, that is, the wound sling can be automatically recovered through a torsion spring (or a motor), so that when the sling drum 15 is not working, there is no need to manually recover the sling, and it is automatically recovered under the action of elastic force.

[0032] It should be noted that in this embodiment, a pair of sling drums 15 are respectively arranged at both ends of the main beam 12 of the sling, and the two ends of the sling are respectively wound on the pair of sling drums 15. The hook is arranged in the middle of the sling, and the two sling drums 15 release and retract the sling synchronously. By setting the paired sling drums 15, the sling and the hook can form a triangular structure, further improving the stability of the lifting and reducing shaking.

[0033] During the loading process, the operator can move the remote control device to the top of the plate material rack 3, operate the device to magnetically fix the ferromagnetic plate or hang the non-ferromagnetic plate, and then move it to the top of the CNC cutting machine table 4 to place the plate on the table. During unloading, the remote control device moves to the top of the CNC cutting machine table 4, re-fixes the processed workpiece, and then moves to the specified position and releases the workpiece.

[0034] 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.
