The second pushing plate 37 is used to push the turnover box 38 to the next process. Specifically, the second linear telescopic driving component and the second pushing plate 37 are used to push the filled turnover box 38 onto the conveyor belt of the next process.

[0047] In this specific embodiment, the first linear telescopic driving component is a first pushing cylinder 35, and the second linear telescopic driving component is a second pushing cylinder 36.

[0048] The automatic palletizing device further includes a positioning linear telescopic component, a mounting frame 41, a horizontal sliding rod 42, and a fourth detection component 43. The positioning linear telescopic component is arranged at the lower part of the frame 1. A positioning hole 39 is provided at the bottom of the turnover box 38 for the power output end of the positioning linear telescopic component to pass through. The positioning linear telescopic component is used to position the turnover box 38 currently being palletized. An installation frame 41 is provided at one end of the turnover box 38 away from the third opening. The horizontal sliding rod 42 is slidably mounted on the installation frame 41 and can extend through one end of the turnover box 38 away from the third opening to the outside. The fourth detection component 43 is arranged on the frame 1 and is used to detect the horizontal sliding rod 42. Both the positioning linear telescopic component and the fourth detection component 43 are connected to the controller.

[0049] Specifically, the positioning linear telescopic component is a positioning cylinder 40. The cylinder body of the positioning cylinder 40 is fixed at the lower part of the frame 1, and the piston rod of the positioning cylinder 40 can extend through the frame 1 into the positioning hole 39 at the bottom of the turnover box 38. The fourth detection component 43 is a fourth proximity switch.

[0050] In this embodiment, a tapered portion is provided at one end of the horizontal sliding rod 42 away from the fourth detection component 43. The cross-sectional area of the tapered portion gradually decreases from the end away from the fourth detection component 43 to the end close to the fourth detection component 43. A tapered hole matching the structure of the tapered portion is provided on the mounting frame 41. Through the above structure, when the horizontal sliding rod 42 is pushed by the sheet parts 45 in the turnover box 38, it is prevented from disengaging from the mounting frame 41.

[0051] In order to achieve continuous production, a plurality of turnover boxes 38 are provided. The plurality of turnover boxes 38 are all slidably mounted on the guiding mechanism, and the second pushing mechanism is arranged at one end of the plurality of turnover boxes 38.

[0052] In this specific embodiment, the number of stacked sheet-like parts 45 in the bin 24 is set to 50, and each turnover box 38 can hold 10 stacks of sheet-like parts 45.

[0053] In this specific embodiment, the grinding device is a double-sided grinding machine, and the sheet-like part 45 is a neodymium iron boron permanent magnet sheet. The width of the sheet-like part 45 is 10 to 20 mm, the length is 30 to 50 mm, and the thickness is 3 to 8 mm. The double-sided grinding machine is used for batch grinding, and the production efficiency is 2 to 5 seconds per piece. To match this production efficiency, this embodiment is equipped with an efficient and automated loading, unloading and palletizing system, which is of general significance for batch processing (such as machining or packaging) of rectangular sheet-like parts 45.

[0054] The specific usage process is as follows: A plurality of sheet-like parts 45 arranged vertically in sequence are placed in the storage box 2. The first pushing cylinder 3 and the first pushing plate 4 push the plurality of sheet-like parts 45, and then a sheet-like part 45 is pushed between the end baffle 11 and the upper surface of the storage box 2. The piston rod of the second pushing cylinder 5 extends, so that the second pushing plate 6 pushes the sheet-like part 45 between the end baffle 11 and the upper surface of the storage box 2 into the part conveying track. Then the piston rod of the second pushing cylinder 5 retracts and waits for the next sheet-like part 45 to be pushed.

[0055] The first rotating motor 12 drives the driving runner 13 to rotate. The driving runner 13 and the driven runner 14 drive a plurality of sheet-like parts 45 to move towards the outlet of the part conveying track under the action of friction. During the transmission process, the second rotating motor 15 drives the grinding wheels 16 to grind both sides of the sheet-like part 45. Then the sheet-like parts 45 pass through the bending chute 18, the arc chute and the connecting chute in sequence from the outlet of the part conveying track and fall onto the pallet body 30 in the bin 24.

[0056] When it is necessary to stack a stack of sheet parts 45 in the bin 24, the controller controls the bin door driving cylinder 31 to drive the bin door body 32 to rise, so that the bin door body 32 closes the second opening of the bin 24. The controller controls the linear stepper motor 27 to drive the pallet body 30 to rise to the set position. When the first detection component 25 detects that a sheet part 45 has fallen onto the pallet body 30, the controller controls the linear stepper motor 27 to drive the pallet body 30 to descend by a distance equal to the thickness of a sheet part 45, and so on. When the first detection component 25 detects that the set number of sheet parts 45 has been stacked, the controller controls the piston rod of the interception cylinder 23 to extend to intercept the sheet parts 45 in the connection chute 20. At the same time, the second detection component 33 detects the connecting plate 28 on the power output end of the linear stepper motor 27. At this time, it means that the sheet parts 45 have been stacked to the set number. The linear stepper motor 27 continues to drive the pallet body 30 to move downward. When the third detection component 34 detects the connecting plate 28 on the power output end of the linear stepper motor 27, it means that the pallet body 30 is flush with the bottom surface of the bin 24. At this time, the controller controls the linear stepper motor 27 to stop moving. The controller controls the bin door driving cylinder 31 to drive the bin door body 32 to descend, so that the second opening of the bin 24 is opened.

[0057] After that, the first pushing cylinder 35 works, so that the first pushing plate pushes a stack of stacked sheet parts 45 into the turnover box 38. And so on, multiple stacks of sheet parts 45 are pushed into the turnover box 38. In the initial state, the horizontal slide bar 42 is located in the turnover box 38 and does not extend out of the turnover box 38. As multiple stacks of sheet parts 45 are pushed into the turnover box 38 by the first pushing cylinder 35, when the turnover box 38 is filled, a stack of sheet parts 45 close to the mounting frame 41 will push the horizontal slide bar 42 to the outside of the turnover box 38. At this time, the fourth detection component 43 detects the horizontal slide bar 42, indicating that the turnover box 38 is filled. The controller controls the piston rod of the positioning cylinder 40 to contract and no longer locks the currently filled turnover box 38. At this time, the second pushing cylinder 36 can push the filled turnover box 38 to the next process.

[0058] While the second pushing cylinder 36 pushes the filled turnover box 38 to the next process, it pushes the adjacent empty turnover box 38 to the position corresponding to the bin 24. At this time, the piston rod of the positioning cylinder 40 extends into the positioning hole 39 of the empty turnover box 38, and then stacking work can continue in the empty turnover box 38.

[0059] In this specification, specific examples are used to illustrate the principles and implementation manners of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation on the present invention.
