Description

Technical Field

[0001] The utility model relates to the technical field of punching sheet centering and orientation, in particular to an automatic centering and orientation transition station. Background Art

[0002] With the widespread application of punching robots, the production processes of different manufacturers are different. The inner and outer circles of the stator punching blanks used for automated production were originally full circles. Now, in order to improve the accuracy of the finished punching, some customers will add a convex marking groove on the outer circle to confirm the position when the blank is blanked. This requires the punching robot to send the punching machine to maintain a fixed direction. In the prior art, a convex marking groove 16 is added to the blank station of the punching robot to limit the position, such as Figure 1 As shown, when loading blanks, the marking grooves are manually aligned. Although this method is feasible, the loading speed will be greatly reduced, and usually only a few sheets can be coded at a time, which takes too long and is inconvenient to operate. Summary of the invention

[0005] Preferably, the driving assembly comprises a servo motor and a planetary reducer, and the planetary reducer is connected to a driving bevel gear via a transition transmission shaft.

[0016] The utility model is further described below.

[0017] See attached Figure 1-2, an automatic centering and directional transition station, comprising a base plate 1, characterized in that: a driving component 2 is arranged at the center of the base plate 1, a plurality of transmission components 3 are evenly arranged on the base plate 1, a slider mounting plate 14 is arranged on the transmission component 3, a rotary motor mounting seat 13 and a positioning mounting seat 8 are arranged on the slider mounting plate 14, a rotary motor 12 is arranged on the rotary motor mounting seat 13, a sheet sorting wheel 11 is arranged on the output shaft of the rotary motor 12, a positioning block 9 is arranged on the upper end of the positioning mounting seat 8, a pallet 5 is connected to the base plate 1 through a pallet support 4, a marking groove limit 7 is arranged on the pallet 5, and a small magnetic proximity switch 6 is arranged on the pallet 5 on one side of the marking groove limit 7.

[0018] In this preferred embodiment, the driving assembly 2 includes a servo motor 21 and a planetary reducer 22 , and the planetary reducer 22 is connected to a driving bevel gear 24 via a transition transmission shaft 23 .

[0019] In this preferred embodiment, the transmission assembly 3 includes a screw front seat 35, a screw rear seat 33, and a linear track lining 32. Both ends of the screw 34 are arranged on the screw front seat 35 and the screw rear seat 33 through bearings. A driven bevel gear 36 is arranged on the inner head of the screw 34. A linear track 38 and a slider 31 are arranged above the linear track lining 32. The slider mounting plate 14 is arranged on the slider 31 and the screw nut 37.

[0020] In this preferred embodiment, the transmission assembly 3 is provided in four groups, and four driven bevel gears 36 are meshed with the driving bevel gear 24 .

[0021] In this preferred embodiment, the film sorting wheel 11 is located between the wheel motor mounting seat 13 and the positioning mounting seat 8. The hole of the film sorting wheel 11 is set on the output shaft of the wheel motor 12, and the other end of the shaft is set in the bearing on the side of the positioning mounting seat 8.

[0022] In the preferred embodiment, the outer ring of the film arrangement wheel 11 is provided with two circles of anti-skid rubber rings 10 .

[0023] In this preferred embodiment, the upper plane of the support plate 5 is lower than the anti-slip rubber ring 10 .

[0024] During specific implementation, the driving component 2 is the power output part of the centering function. A non-centered and oriented punching sheet falls to the transition station and is lifted on the anti-slip rubber ring 10. The servo motor 21 works, and a driving bevel gear 24 drives four driven bevel gears 36. The four evenly distributed positioning will move inward / outward at the same time under the action of the transmission component 3, and finally the center of the punching sheet is positioned. After this position is determined, the rotary motor 12 works, and the sheet sorting wheel 11 rotates to drive the punching sheet to rotate together. Due to the positioning limitation, the center position of the punching sheet will not change. When the convex marking groove 16 reaches the marking groove limit 7, the punching sheet is blocked and no longer rotates. The magnetic proximity switch 6 next to the marking groove limit 7 senses the convex marking groove 16, and the rotary motor 12 stops working until the punching sheet is taken away, and the servo motor 21 controls the positioning to return to its original position.
