[0030] The loading rack 7 includes a bracket 22 fixed on the workbench 2, and a platform 23 arranged on the top of the bracket 22. The platform 23 is provided with a receiving hole 24. The center of the receiving hole 24 is collinear with the center of the tooling plate 4 at the middle position of the workbench 2. The magnetic spreader 8 surrounds the receiving hole 24. Two initial positioning devices 25 are provided on the bracket 22. The initial positioning device 25 includes a push cylinder 26 and a push plate 27 arranged on the stroke rod of the push cylinder 26.

[0031] The cross section of the flat push plate 27 is triangular, and the flat push plate 27 is a hollow structure. The flat push plate 27 of the hollow structure has a buffering elastic effect and prolongs the service life.

[0033] The centering mechanism 9 is arranged on the platform 23, including a centering cylinder 28, two centering pins 29 and a universal roller 21 between the centering cylinder 28 and the centering pin 29. A push plate 30 is provided on the stroke rod of the centering cylinder 28. The pushing direction of the push plate 30 is perpendicular to the line connecting the two centering pins 29, and the line connecting the push plate 30 and the two centering pins 29 together form an isosceles triangle.

[0034] The working principle of the plate feeding device of the present invention is described below:

[0035] The plate feeding device of the present invention is mainly used for feeding circular plates 32. First, the two tooling plates 4 are moved left, middle and right through the translation mechanism 3, that is, the motor 10 drives the gear 11 to rotate on the rack 12, so that the two tooling plates 4 connected by the motor seat 13 move synchronously. When one workstation is moved, the two tooling plates 4 are respectively in the left and middle positions or the right and middle positions. Here, we take the two tooling plates 4 in the left and middle positions as an example. At this time, the lifting seat 20 of the left and middle lifting mechanisms 5 is facing the through hole 6 in the center of the tooling plate 4, and the lifting cylinder 19 of the left lifting mechanism 5 makes the lifting seat 20 pass through the through hole 6 and rise, and then, it is lifted by a forklift. The equipment moves the stacked plates to the position of the lifting seat 20 and places the plates on the lifting seat 20. A sign that the plates are in place here is that the side walls of the plates touch the inner walls of the two limit plates 18 at the same time. Then the lifting seat 20 descends, so that the plates fall steadily into the plate accommodating space 16 formed by the plurality of positioning plates 15. Since the inner upper edge of the positioning plate 15 is provided with a guide slope 31, the plates can fall into the plate accommodating space better and smoothly without being supported on the positioning plate 15. Then, the translation mechanism 3 drives the two tooling plates 4 to move one station in the right direction, and the tooling plate 4 at the original left position reaches the middle position. The tooling plate 4 reaches the right position. At this time, the plate can be placed on the tooling plate 4 that has reached the right position. At the same time, the plate on the tooling plate 4 in the middle position is facing the receiving hole 24 in the center of the platform 23 of the loading rack 7. In order to improve the concentricity of the plates after stacking, the plates on the tooling plate 4 in the middle position are initially centered by the initial positioning device 25. Specifically, the lifting cylinder 19 of the middle lifting mechanism 5 works to drive the lifting seat 20 to rise through the through hole 6, so that the plate rises to a certain height, which is based on the plate leaving the tooling plate 4. Then the push cylinder 26 drives the push plate 27 to push the outer peripheral surface of the plate. The two limit plates 18 and the two flat push plates 27 are arranged opposite to each other, so that one side wall of the plate is blocked by the two limit plates 18, and the other side is pushed by the two flat push plates 27. The height of the flat push plates 27 is greater than or equal to the height of the superimposed plates, so that the outer peripheral surface of each plate moves in the direction of being in contact with the limit plates 18 and the flat push plates 27 at the same time. Since the lifting seat 20 has a universal roller 21, the plate contacts the universal roller 21, so that the flat push plates 27 can push the plate more easily, thereby achieving the purpose of each plate being approximately concentric, and also providing a prerequisite for the plate to pass through the accommodating hole 24 to reach the position of the magnetic spreader 8;Then, the lifting cylinder 19 of the middle lifting mechanism 5 continues to work. The stroke of the lifting cylinder 19 at this position is larger than that of the two lifting cylinders 19 on the left and right. As the lifting seat 20 continues to rise, the plate in the plate accommodating space 16 is lifted up. As the plate continues to rise, when the plate passes through the accommodating hole 24 of the platform 23 and is in the working range of the magnetic spreader 8, the two adjacent plates are separated. At this time, the manipulator can be used to clamp the top plate and move it to the universal roller position 0 of the positioning mechanism 0, so that the plate is within the area of ​​the isosceles triangle formed by the connecting line between the push plate 30 and the two centering pins 29. At this time, the push plate 30 is acted upon by the centering cylinder 28 to push the plate toward the two centering pins 29. When the plate contacts and abuts against the two centering pins 29 at the same time, it indicates that the plate is centered in place. At this time, the manipulator can clamp the precise position of the plate, so that the plate placed in the processing equipment can be placed in place. ;

[0036] When the plates on the tooling plate 4 in the middle position are clamped, the motor 10 drives the two tooling plates 4 to move one station to the left. At this time, the tooling plate 4 with the plates placed on the original right position moves to the middle position to continue loading the next group of plates, and so on.

Specific examples are used herein to illustrate the principle and implementation mode of the present invention. The description of the above embodiments is only used to help understand the technical solution disclosed by the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be understood as a limitation of the present invention.
