DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0053] When the feeding device is working, the feeding assembly 4 is first raised until the feeding assembly 4 is higher than the lower die of the punch press 6 and does not interfere with each other; the three groups of the fixing assemblies 2 fix the stacked plates in the holding assembly 3; the holding assembly 3 raises the stacked plates to be processed until the stacked plates to be processed are higher than one plate to be processed of the holding assembly 3, and the ejecting assembly 1 ejects the plates to be processed to the feeding assembly 4; the feeding assembly 4 clamps and fixes the plates, and then rotates to place the plates above the lower die of the punch press 6. At this time, the height of the feeding assembly 4 is adjusted so that the plates fit the upper surface of the lower die of the punch press 6; after the processing is completed, the feeding assembly 4 is raised until the feeding assembly 4 does not interfere with the lower die of the punch press 6 when rotating. After the feeding assembly 4 rotates, the stamped plates are ejected from the feeding assembly 4 and stored in the corresponding position.

[0054] The ejection assembly 1 includes a first fixing seat 101, a first cylinder 102, an ejection plate 103 and a clamping groove 104.

[0076] First, the second electro-hydraulic push rod 4016 is used to make the clamping assembly 403 located above the lower die of the punch press 6, and the clamping assembly 403 and the components of the punch press 6 do not interfere with each other; the fixing assembly 2 fixes the stacked panels to be processed in the material holding assembly 3 and is located on the supporting plate 304; secondly, the upper plate surface of the uppermost plate of the stacked panels to be processed is flush with the upper end surface of the third baffle plate 302, and by setting the extension length of the first electro-hydraulic push rod 303 each time to the length of the thickness of the panel to be processed, the ejecting plate 103 can eject a panel to be processed into the clamping assembly 403 each time, so that one end of the panel to be processed is clamped in the fifth slide groove 40311, and the other two symmetrical ends are clamped in the fourth slide groove 4038; then, the fourth cylinder 40352 is used to make the fixing rod 40353 fix the panel to be processed through the fixing hole 40310, so that the panel to be processed is fixed in the clamping assembly 403; then, The servo motor 4014 causes the clamping assembly 403 to rotate to the lower die of the punch press 6, and the second electro-hydraulic push rod 4016 causes the plate to be processed to fit tightly with the lower die of the punch press 6. When the plate to be processed is processed, it rises to its original position again through the second electro-hydraulic push rod 4016. At this time, the servo motor 4014 is started again to rotate the processed plate out of the punch press 6; the fourth cylinder 40352 causes the fixing rod 40353 to return to its original position through the fixing hole 40310, and releases the fixed processed plate. At the same time, the third cylinder 4023 at the processed plate is started, and one end of the output shaft of the third cylinder 4023 ejects the processed plate from the clamping assembly 403 through the ejection hole 40332 until it is detached; finally, the above steps are repeated, and the loading device can load and unload materials quickly and effectively, and there will be no situation where the existing mechanical arm fails to adsorb or adsorbs multiple plates at a time.
