The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0022] The present invention relates to an automated processing equipment for stator and rotor punchings. For example, the automated processing equipment for stator and rotor punchings includes a stamping mechanism, a transfer component and a detection mechanism, and the transfer component is arranged between the stamping mechanism and the detection mechanism. For example, the detection mechanism includes a base, a rotating component and an automatic detection component, and the rotating component includes a bracket, a rotating cylinder and a toggle rod, and the bracket is installed on the base. For example, the rotating cylinder is installed on the top of the bracket, and the toggle rod is connected to the rotating cylinder and is used to toggle the stator and rotor punchings to rotate. For example, the automatic detection component is arranged at the bottom of the base, and is used to detect the stator and rotor punchings.

[0023] See also Figures 1 to 3 , an automated processing equipment for stator and rotor punching sheets, including a stamping mechanism, a transfer component 10 and a detection mechanism 40, the transfer component 10 is arranged between the stamping mechanism and the detection mechanism 40, the detection mechanism 40 includes a base 41, a rotating component 43 and an automatic detection component, the rotating component 43 includes a bracket 431, a rotating cylinder 433 and a toggle rod 435, the bracket 431 is installed on the base 41, the rotating cylinder 433 is installed on the top of the bracket 431, the toggle rod 435 is connected to the rotating cylinder 433 and is used to toggle the stator and rotor punching sheets 100 to rotate, the automatic detection component is arranged at the bottom of the base 41, and is used to detect the stator and rotor punching sheets 100.

[0024] After the automatic processing equipment for the stator and rotor punching sheets is used, the punching mechanism punches the stator and rotor punching sheets 100, and the transfer component 10 transfers the stator and rotor punching sheets 100 to the base 41, and then the automatic detection component automatically detects the stator and rotor punching sheets 100, after which the stator and rotor punching sheets 100 can be transferred to the next process. Since the automatic processing equipment is provided with an automatic detection component, the automatic detection component can be used to automatically detect the stator and rotor punching sheets 100, which greatly improves the detection efficiency, and also improves the processing efficiency of the stator and rotor punching sheets 100.

[0025] For example, in order to facilitate the transfer of the stator and rotor punching sheets 100, the transfer assembly 10 includes a rotating drive member 11, a connecting arm 12, a lifting drive member 13 and a grabbing member 15, wherein the connecting arm 12 is connected to the rotating drive member 11, the lifting drive member 13 is connected to the connecting arm 12, and the grabbing member 15 is connected to the lifting drive member 13. The connecting arm 12 is an L-shaped connecting arm, and a cross bar is formed at the top of the connecting arm 12, and the lifting drive member 13 is installed at the end of the cross bar. The transfer assembly 10 also includes a transfer table 16, which is arranged between the stamping mechanism and the base 41, and is used to support the stator and rotor punching sheets 100. The transfer table 16 includes a support frame 161 and a circular table 162, and the circular table 162 is fixed to the top of the support frame 161. By providing the transfer table 16 , the stator and rotor punching sheets 100 can be conveniently transferred, so that the stator and rotor punching sheets 100 can be conveniently transferred to the base 41 of the detection mechanism 40 .

[0026] For example, in order to facilitate the transfer of the stator and rotor punching sheets 100, the grabbing member 15 is disc-shaped, and the grabbing member 15 includes a middle disc 151 and a plurality of elastic grabbing strips 153 protruding from the periphery of the middle disc 151. The elastic grabbing strips 153 extend outward and downward, and the plurality of elastic grabbing strips 153 are iron sheet grabbing strips, and a folded edge grabbing portion is formed at the end thereof. The folded edge grabbing portion extends horizontally toward the central axis direction of the middle disc 151, and the folded edge grabbing portion is connected to the elastic grabbing strip 153 in an arc shape. By providing the plurality of elastic grabbing strips 153 and the plurality of folded edge grabbing portions. When the lifting drive member 13 drives the multiple elastic grabbing strips 153 to descend and press the stator and rotor punching sheet 100, the multiple elastic grabbing strips 153 bend and deform, and prompt the multiple folded edge grabbing parts to move outward to the outer periphery of the stator and rotor punching sheet 100. Thereafter, the lifting drive member 13 drives the grabbing member 15 to rise, so that the multiple elastic grabbing strips 153 move away from the stator and rotor punching sheet 100 and automatically shrink. At this time, the multiple folded edge grabbing strips retract and clamp the periphery of the stator and rotor punching sheet 100, and then the stator and rotor punching sheet 100 is grabbed by the multiple folded edge grabbing strips.

[0027] For example, in order to facilitate the detection of whether the stator and rotor punching sheet 100 has a complete winding groove 101, a circular detection surface is formed on the base 41, and a plurality of narrow slots are opened on the circular detection surface, and each narrow slot extends radially outwardly along the circular detection surface. The automatic detection component includes a disc and a plurality of proximity switches arranged on the disc, and each proximity switch is aligned with one of the narrow slots. Through the rotation of the stator and rotor punching sheet 100, the winding groove 101 on the stator and rotor punching sheet 100 can pass through the narrow slot. If the plurality of proximity switches detect the winding groove 101 at the same time, it is determined that the winding groove 101 of the stator and rotor punching sheet 100 is complete and uniform. If any of the proximity switches does not detect the winding groove 101, it is determined that the winding groove 101 of the stator and rotor punching sheet 100 is incomplete, and the stator and rotor punching sheet 100 is determined to be a defective product. For example, each group of proximity switches includes two proximity switches, and the two proximity switches are respectively arranged at the opposite ends of the corresponding narrow slot to detect whether the two ends of each winding groove 101 are complete.

[0028] For example, it is especially important to also refer to Figure 4, the diameter of the circular table 162 is equal to the diameter of the stator and rotor punching 100, so that the multiple folding edge grabbing parts can move to the bottom edge of the circular table 162 and pick up the stator and rotor punching 100 from the bottom of the periphery of the stator and rotor punching 100. In order to facilitate the realization of automated detection, the base 41 includes an inclined descending portion 411 and a platform portion 412 connected to each other, the surface of the platform portion 412 is parallel to the horizontal plane, and the circular detection surface is formed on the platform portion 412. The first blocking bar 413 and the second blocking bar 414 are respectively protruded on both sides of the top of the base 41, and the distance between the first blocking bar 413 and the second blocking bar 414 is equal to the diameter of the stator and rotor punching 100. A stopping rib is protruded on one end of the platform portion 412 away from the inclined descending portion 411, which is used to stop the stator and rotor punching 100 sliding down from the inclined descending portion 411. For example, the bracket 431 is an L-shaped bracket and is installed on the first retaining strip 413. The rotating cylinder 433 is located above the platform portion 412 and is aligned with the center of the circular detection surface. The rotating assembly 43 also includes two connecting rods 434 and an ejection rod 439. The two connecting rods 434 are laterally protruded on opposite sides of the output shaft of the rotating cylinder 433, and an obtuse angle is formed between the two connecting rods 434. The top end of the toggle rod 435 is vertically connected to the end of one of the connecting rods 434, and the top end of the ejection rod 439 is vertically connected to the end of the other connecting rod 434. A lifting cylinder 436 is provided at the top end of the toggle rod 435. The distance between the ejection rod 439 and the central axis of the output shaft of the rotating cylinder 433 is a first distance, and the first distance is less than the radius of the stator and rotor punching 100. The distance between the toggle rod 435 and the central axis of the output shaft of the rotating cylinder 433 is a second distance, and the second distance is slightly larger than the radius of the stator and rotor punching 100. The length of the ejection rod 439 is smaller than the length of the toggle rod 435. The bottom of the toggle rod 435 is provided with a toggle block 4355, and the toggle block 4355 is rotatably connected to the bottom end of the toggle rod 435 through a first torsion spring. The bottom surface of the toggle block 4355 is used to slidably abut against the circular detection surface.

[0029] The first stop bar 413 and the second stop bar 414 are respectively provided with a first notch 4135 and a second notch 4145, and the first notch 4135 and the second notch 4145 are respectively located on opposite sides of the circular detection surface. The first notch 4135 is located on the side of the circular detection surface facing the inclined descending portion 411, and the second notch 4145 is aligned with the middle of the circular detection surface. A push-out slot 4136 is extended from the bottom of the first notch 4135 toward one side of the inclined descending portion 411, and the width of the push-out slot 4136 is equal to the thickness of the stator and rotor punching 100. A retaining assembly 50 is rotatably provided on one side of the first notch 4135 away from the inclined descending portion 411. The retaining assembly 50 includes a retaining plate 51, a second torsion spring 52 and a retaining roller 53. The retaining plate 51 is rotatably provided on the edge of the platform portion 412 through the second torsion spring 52. A retaining column is provided at the bottom of the platform portion 412. The retaining column retains the retaining plate 51 so that the retaining plate 51 is maintained on the edge of the platform portion 412 and can only be opened outwards but cannot be moved inwards to the circular detection surface. The retaining roller 53 is rotatably mounted on the retaining plate 51 and abuts against the platform portion 412. An inclined surface 515 is formed on the top of the retaining plate 51, and the inclined surface 515 extends outwards and downwards. The end of the stop plate 51 is formed with an arc-shaped guide surface 518, which faces the first notch 4135 and smoothly connects with the periphery of the stator and rotor punching 100. The toggle block 4355 elastically abuts against the outer side of the stop plate 51. A potential energy block 4148 is arranged in the second notch 4145, and the thickness of the potential energy block 4148 gradually increases in the direction away from the inclined descending portion 411. The potential energy block 4148 is respectively formed with an introduction surface and a cross section at opposite ends, the introduction surface is on the side facing the inclined descending portion 411, and the cross section passes vertically through the center of the stator and rotor punching 100. The bottom end position of the ejector rod 439 is lower than the top surface position of the stop plate 51.

[0030] When the detection mechanism 40 is in use, the grabbing member 15 is used to drive the stator and rotor to move to the inclined descending portion 411, and the grabbing member 15 is held against the inclined descending portion 411 to force the multiple elastic grabbing strips 153 to expand outward to drive the multiple folded edge grabbing portions radially outward away from the stator and rotor punching 100. The position of the folded edge grabbing portion after movement is flush with the bottom surface of the stator and rotor punching 100 and will not be lower than the stator and rotor punching 100. Thereafter, the grabbing member 15 moves upward, so that the multiple folded edge grabbing portions can only move along the circumferential surface of the stator and rotor punching 100, and finally release the stator and rotor punching 100. Thereafter, the stator and rotor punching sheet 100 descends along the inclined descending portion 411 to the platform portion 412 , and is guided by the first blocking strip 413 and the second blocking strip 414 , and is stopped and positioned by the stopping rib and the holding roller 53 , so that the stator and rotor punching sheet 100 can be positioned and aligned with the circular detection surface. The rotating cylinder 433 drives the toggle rod 435 to rotate and align with the stop plate 51, and the lifting cylinder 436 drives the toggle rod 435 to drive the toggle block 4355 to descend. The toggle block 4355 rotates and abuts against the outer side of the stop plate 51 under the guidance of the inclined surface 515 of the stop plate 51, and then the rotating cylinder 433 drives the two connecting rods 434 to rotate, so that the toggle rod 435 moves along the arc-shaped guide surface 518 of the first notch 4135 to the circumference of the stator and rotor punching 100, and the toggle block 4355 abuts against the circumference of the stator and rotor punching 100 under the action of the first torsion spring. Then the toggle block 4355 drives the stator and rotor punching 100 to rotate through friction to cooperate with the automatic detection component for detection. Afterwards, the toggle block 4355 moves into the potential energy block 4148 under the guidance of the guide surface of the second notch 4145, forcing the first torsion spring to tighten to increase the elastic potential energy. At this time, the ejection rod 439 abuts against the blocking roller 53 to force the stop plate 51 to rotate outward to overcome the elastic force of the second torsion spring 52, thereby expanding the first notch 4135. When the toggle block 4355 moves to the cross section of the potential energy block 4148, the toggle block 4355 quickly returns to its original position under the elastic restoring force of the first torsion spring and hits the stator and rotor punching sheet 100, so that the stator and rotor punching sheet 100 is pushed out of the first notch 4135, the ejection slot 4136 and the position of the stop plate 51 rotated out onto the platform portion 412 to enter the next station. For example, the size of the toggle block 4355 is larger than the width of the winding groove 101 of the stator and rotor punching sheet 100. By providing the rotating assembly 43, the stator and rotor punching sheets 100 can be conveniently driven to rotate so that the multiple winding grooves 101 thereon are aligned with the multiple narrow slots on the circular detection surface, so as to facilitate the detection.The potential energy block 4148 is provided to facilitate the toggle block 4355 to hit the stator and rotor punching 100 so as to push it out of the platform portion 412. The push-out slot 4136 and the push-out rod 439 are provided to facilitate the rotation of the stop plate 51 so as to facilitate the push-out of the stator and rotor punching 100.
