[0036] The automatic stacking device includes a first pushing mechanism and a second pushing mechanism. The stacking and storage device includes a silo 24, a liftable pallet, a liftable silo door and a turnover box 38. The silo 24 and the turnover box 38 are both arranged on the frame 1. The top and bottom of the silo 24 respectively have a top opening and a bottom opening. The liftable pallet can pass through the bottom opening and extend into the silo 24. The outlet at the lower end of the posture conversion device is connected with the top opening. The posture conversion device is used to convert the vertical sheet parts 45 into a horizontal state and fall onto the liftable pallet in the silo 24, that is, the posture conversion device is used to convert the sheet parts 45 from an upright processing state to a horizontal induction state. The first opening and the second opening are respectively provided on both sides of the silo 24. The first pushing mechanism is provided on the side close to the first opening.

Then the second pushing mechanism pushes the turnover box 38 containing multiple stacks of sheet parts 45 to the next process.

[0040] The transmission mechanism includes a transmission track and a power assembly. The transmission track includes a first track plate 7, a second track plate 8, an end baffle 11 and two connecting assemblies. The first track plate 7 is arranged above the second track plate 8, and there is a gap between the first track plate 7 and the second track plate 8.

The central axes of the driving wheel 13 and the driven wheel 14 are perpendicular to the plane where the pushing direction of the first pushing mechanism and the transmission direction of the transmission mechanism are located.

[0042] During operation, the driving wheel 13 rotates, and under the action of friction, the sheet part 45 moves toward the outlet of the transmission mechanism, and the driven wheel in contact with the sheet part 45 follows the rotation, thereby causing the transmission to be performed under the action of the driving wheel 13 and the driven wheel 14.

[0047] In this specific embodiment, the first pushing linear telescopic driving component is the first pushing cylinder 3 , and the second pushing linear telescopic driving component is the second pushing cylinder 5 .

The axial direction of each grinding wheel 16 is consistent with the pushing direction of the first pushing mechanism. The two grinding wheels 16 are respectively used to grind the two sides of the sheet part 45.

[0049] Specifically, the second rotary drive component is a second rotary motor 15, and the grinding wheel 16 is fixedly sleeved on the power output shaft of the second rotary motor 15. Grinding openings are provided on the two symmetrically arranged vertical plates 9 in the middle of the transmission mechanism.

[0050] The posture conversion device includes a connecting slide, an arc slide 19 and a connecting slide 20. One end of the connecting slide is connected to the outlet of the transmission mechanism, and the other end of the connecting slide is connected to the inlet of the arc slide 19. The outlet of the arc slide 19 is connected to one end of the connecting slide 20, and the other end of the connecting slide 20 is connected to the top opening.

[0051] Specifically, the connecting slide includes a slide plate 17 and a cover plate. One end of the slide plate 17 is connected to the end of a connecting component away from the holding box 2. One end of the cover plate is connected to the end of another connecting component away from the holding box 2. The cover plate is fixed to one side of the slide plate 17.

[0052] The curved chute 18 in this embodiment is a chute with a 90-degree turning angle, and cooperates with the arc chute and the connecting chute, so that the sheet component 45 slides into the hopper 24 at a safe and stable speed under the action of gravity.

[0053] Specifically, the blocking piece 21 includes a fixed piece and a limiting piece provided at one end of the fixed piece. The two ends of the fixed piece are respectively fixed to the top two sides of the connecting chute.

The piston rod of the intercepting cylinder 23 can pass through the limiting piece and extend into the connecting chute and abut against the bottom surface of the connecting chute.

[0054] The intercepting linear telescopic component in this embodiment works in conjunction with the first detection component 25. When the first detection component 25 detects that the number of falling sheet parts 45 reaches a set value, the controller controls the power output end of the intercepting linear telescopic component to extend to intercept the sheet parts 45 in the connecting slide 20, thereby completing the stacking of a stack of sheet parts 45. When the next stack of sheet parts 45 needs to be stacked, the controller controls the power output end of the intercepting linear telescopic component to retract so that it no longer intercepts the sheet parts 45 in the connecting slide 20.

The first pushing plate matches the first opening structure of the hopper 24 and is used to push the stacked stack of sheet parts 45 into the turnover box 38. The second pushing mechanism includes a second linear telescopic driving component and a second pushing plate 37 disposed at the power output end of the second linear telescopic driving component. 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.

[0061] In this specific embodiment, the first pushing linear telescopic driving component is a first pushing cylinder 35 , and the second linear telescopic driving component is a second pushing cylinder 36 .

[0062] The automatic palletizing device also includes a positioning linear telescopic component, a mounting frame 41, a horizontal slide bar 42, and a fourth detection component 43. The positioning linear telescopic component is arranged at the lower portion of the frame 1. The bottom of the turnover box 38 is provided with a positioning hole 39 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 stacked. A mounting frame 41 is provided at the end of the turnover box 38 away from the third opening. The horizontal slide bar 42 is slidably mounted on the mounting frame 41 and can extend to the outside through the end of the turnover box 38 away from the third opening. The fourth detection component 43 is arranged on the frame 1 and is used to detect the horizontal slide bar 42. The positioning linear telescopic component and the fourth detection component 43 are both connected to the controller.

[0063] Specifically, the positioning linear telescopic component is a positioning cylinder 40, the cylinder body of which is fixed to the lower portion of the frame 1, and the piston rod of which can pass through the frame 1 and extend into the positioning hole 39 at the bottom of the turnover box 38. The fourth detection component 43 is a fourth proximity switch.

[0064] In this embodiment, a tapered portion is provided at the end of the horizontal slide bar 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, the horizontal slide bar 42 is prevented from falling off the mounting frame 41 when pushed by the sheet part 45 in the turnover box 38.

[0065] In order to achieve continuous production, a plurality of turnover boxes 38 are provided, and the plurality of turnover boxes 38 are all slidably mounted on the guide mechanism, and the second pushing mechanism is provided at one end of the plurality of turnover boxes 38 .

[0066] In this specific embodiment, the number of the stack of sheet parts 45 stacked in the silo 24 is set to 50, and each turnover box 38 can hold 10 stacks of sheet parts 45 .

[0067] In this specific embodiment, the grinding device is a double-end surface grinder, and the sheet-shaped component 45 is a NdFeB strong magnetic sheet. The sheet-shaped component 45 has a width of 10 to 20 mm, a length of 30 to 50 mm, and a thickness of 3 to 8 mm. Using the double-end surface grinder for batch grinding achieves a production efficiency of one piece per 2 to 5 seconds. To support this production efficiency, this embodiment is equipped with an efficient and automated loading and unloading and palletizing system. This system is universally applicable to batch processing (such as processing or packaging) of rectangular sheet-shaped components 45.

[0068] The specific usage process is as follows: multiple sheet parts 45 are placed in a vertical state and arranged in sequence in the holding box 2, the first pushing cylinder 3 and the first pushing plate 4 push the multiple sheet parts 45, and then push a sheet part 45 to between the end baffle 11 and the upper surface of the holding box 2, the piston rod of the second pushing cylinder 5 is extended, so that the second pushing plate 6 pushes the sheet part 45 between the end baffle 11 and the upper surface of the holding box 2 to the part conveying track, and then the piston rod of the second pushing cylinder 5 is retracted, waiting for the next sheet part 45 to be pushed.

[0069] The first rotating motor 12 drives the active wheel 13 to rotate, and the active wheel 13 and the driven wheel 14 drive multiple sheet parts 45 to move toward the exit of the parts conveying track under the action of friction. During the transmission process, the second rotating motor 15 drives the grinding wheel 16 to grind both sides of the sheet parts 45. Then, the sheet parts 45 pass through the curved chute 18, the arc chute and the connecting chute from the exit of the parts conveying track and fall onto the pallet body 30 in the hopper 24.

[0070] When a stack of sheet parts 45 needs to be stacked in the silo 24, the controller controls the door drive cylinder 31 to drive the door body 32 to rise, so that the door body 32 closes the second opening of the silo 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 the thickness of a sheet part 45. Similarly, when the first detection component 25 detects that a set number of sheet parts 45 have been stacked, the controller controls the piston rod of the interception cylinder 23 to extend to intercept the sheet parts 45 in the connecting slide 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, which indicates that the sheet parts 45 have been stacked to the set number. The linear stepper motor 27 continues to drive the pallet body 30 downward. When the third detection component 34 detects the connecting plate 28 on the power output end of the linear stepper motor 27, indicating that the pallet body 30 is flush with the bottom surface of the silo 24, the controller controls the linear stepper motor 27 to stop moving. The controller controls the door drive cylinder 31 to drive the door body 32 downward, opening the second opening of the silo 24.

[0071] Afterwards, the first pushing cylinder 35 works, causing the first pushing plate to push the stacked stack of sheet parts 45 into the turnover box 38. Similarly, 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 from 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 full, a stack of sheet parts 45 near the mounting frame 41 pushes 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 full. The controller controls the piston rod of the positioning cylinder 40 to retract 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.

[0072] While the second pushing cylinder 36 pushes the filled turnover box 38 to the next process, it also pushes the empty turnover box 38 adjacent to the filled turnover box 38 to the position corresponding to the silo 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 the stacking work can continue in the empty turnover box 38.

The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
