Specifically, the fourth motor 561 drives the longitudinal moving frame 567 to move up and down along the third linear guide 565, so as to drive the grinding head on the longitudinal moving frame 567 to reciprocate up and down, so that the grinding heads at different positions on the rough grinding head 555 grind the edge of the plate, and the effect of reasonably and fully utilizing the grinding head can be achieved.

Specifically, the spring 544 is sleeved on the fifth linear guide 543. The tray has various shapes, such as a round tray, a square tray or other shaped trays. When the rough grinding head 555 is close to the plate and is in contact with the edge of the plate for grinding, the rough grinding head 555 can be pushed due to different bulges on the edge of the plate (such as a square plate), and the rough grinding head 555 can move along the fourth linear guide 541 for fine adjustment according to the change of the edge of the plate so as to adapt to the change of the shape of the edge of the plate. At present, most of edge grinding mechanisms are only provided with motors which drive grinding heads to move for fine adjustment through gears and racks so as to adapt to changes of the edge appearance of the plate, but because the speed of the motors adapting to changes is poor, the speed of the edge appearance of the plate is changed fast under the driving of the clamping rotating assembly 53a, the speed of the grinding heads moving the fine adjustment position cannot follow the speed of the changes of the edge appearance of the plate, and therefore the plate grinding effect is poor. The springs 544 can be additionally arranged to play a role in pressure equalization when the rough grinding heads 555 are moved and finely adjusted, that is, in the process that the plate rotates and is matched with the rough grinding heads 555 for grinding, the rough grinding heads 555 can be moved and finely adjusted through different compression degrees of the springs 544 to be matched with the change of the shape speed of the edge of the plate for grinding better and faster, so that the grinding effect is better.

Specifically, the grinding heads of the first rough grinding head assembly 55a and the second rough grinding head assembly 55b respectively grind the edges of the plates on the two plate conveying mechanisms, so that compared with a single-side grinding mechanism, the production efficiency of grinding can be improved, and the processing cost can be reduced.

The rotating rod 532 is rotatably connected with the rough edging mechanism stand 51 through a bearing. The second fixing frame 535 is located right below the upper clamping head 533. The upper end of the second fixing frame 535 is fixedly installed on the rack 10 between the conveying frames 406, and the lower end of the second fixing frame 535 is fixedly installed with the third cylinder 534. The piston rod of the third cylinder 534 movably penetrates the second fixing frame 535 and is connected with one end of the push rod 536, and the other end of the push rod 536 is fixedly connected with the lower clamping head 537. And a second rubber rotary head 538 rotatably connected with the lower clamping head 537 is arranged at the upper end of the lower clamping head 537. The upper end of the second rubber swivel 538 is dug with a plurality of grooves to increase the friction force when contacting with the plate. The push rod 536 is slidably coupled to the frame via a guide sleeve. The third cylinder 534 pushes the dishes on the dish conveying mechanism 40 and above the lower clamping head 537, and drives the dishes to move upward to contact the upper clamping head 533, so that the dishes are clamped by the upper clamping head 533 and the lower clamping head 537; the fifth motor 531 drives the upper clamping head 533 to rotate the plate. The rubber rotor does not pinch or damage the surface of the member to be ground, so that the plate is rotated together with the clamping and rotating assembly 53 to grind along the shape of the plate. After the rough grinding head 555 finishes processing the edges of the plates, the third cylinder 534 drives the lower clamping head 537 to move downwards to place the plates on the transmission belt 403, and the plates are conveyed to the fine edge grinding mechanism 60 through the transmission belt 403.

Referring to fig. 1 and 8, the fine edging mechanism 60 has the same structure as the rough edging mechanism 50. The grinding head connecting rod on the fine grinding edge mechanism 60 is connected with a fine grinding head 61. The structure of the tray placing mechanism 70 is the same as that of the tray taking mechanism 30. The processed plate placing frame 80 is used for placing plates with edges polished. The processed disk rack 80 is a conventional rack, which is well known in the art, and therefore the structure thereof is not described herein.

Specifically, in the utility model, the rough grinding head 555 is a carborundum wheel grinding head, and the fine grinding head 61 is a sponge abrasive belt wheel grinding head; the rough grinding head 555 realizes rough grinding of the piece to be ground, and the fine grinding head 61 realizes fine grinding and burr removal of the piece to be ground.

Further, the tray may be a tray, a dinner plate, a flat plate, a fruit tray, etc., and the shape of the tray may be a disc, a square plate, or other shapes, which is not limited herein. The full-automatic plate edge grinding machine does not limit the edge grinding to the plate, and can also grind other articles such as soles.

The utility model discloses a theory of operation: the plates are stacked between the limiting columns 203, and the suction heads 307 on the two plate taking mechanisms 30 suck the plates and respectively place the plates on the transmission belts 403 of the two plate conveying mechanisms 40. The belt 403 of the tray conveying mechanism 40 conveys the trays to the upper side of the lower clamping head 537, and the third cylinder 534 pushes the lower clamping head 537 to move the trays upward to contact the upper clamping head 533 and clamp the trays. The fifth motor 531 drives the upper clamping head 533 to rotate the plate. The third motor 554 and the second motor 545 of the first rough grinding head assembly 55a drive the rough grinding heads 555 to rotate and move to one side, so that the rough grinding heads 555 of the first rough grinding head assembly 55a and the plate edge of the first clamping and rotating assembly 53a are in contact friction to achieve the edge grinding process. After finishing grinding, the third motor 554 and the second motor 545 of the second rough grinding head assembly 55b drive the rough grinding head 555 to rotate and move to the other side, so that the rough grinding head 555 of the second rough grinding head assembly 55b contacts and rubs against the edge of the plate of the second clamping and rotating assembly 53b to achieve the edge grinding process. The dish that the rough edging was accomplished is put back through centre gripping rotating assembly 53 on the drive belt 403, the process drive belt 403 carries rough edging mechanism 50 position and carries out dish finish edging processing. And finally, the plate which is edged is placed on the processed plate placing frame 80 through the plate placing mechanism 70, so that the double-station full-automatic edging processing of the plate is realized.
