[0029] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] The present invention provides a stacking device, such as Figure 1 and Figure 2As shown, it includes a frame 1, on which a feeding mechanism 2, a material holding block 3 and a driving mechanism 4 are arranged. The feeding mechanism 2 and the material holding block 3 are arranged in parallel. Fig.10 As shown, a stacking bin channel 31 is provided in the material holding block 3; a material moving mechanism 5 is provided on the driving mechanism 4; the driving mechanism 4 drives the material moving mechanism 5 to reciprocate between the loading mechanism 2 and the material holding block 3, thereby transferring the workpiece from the loading mechanism 2 to the stacking bin channel 31. The stacking bin channel 31 is arranged to extend in the vertical direction, and the stacking bin channel 31 is used to accommodate the workpiece; the cross-sectional shape of the stacking bin channel 31 is the same as the cross-sectional shape of the workpiece, so that the stacking bin channel 31 matches the appearance shape of the workpiece, thereby preventing the workpiece from flipping when falling in the stacking bin channel 31.

[0031] The workpiece described in the present invention is a special-shaped iron core; after the staff pours a large batch of workpieces into the loading mechanism 2, the loading mechanism 2 is used to load the workpieces; the driving mechanism 4 drives the moving mechanism 5 to move, thereby transferring the workpieces from the loading mechanism 2 to the stacking bin channel 31, and the workpieces are stacked and arranged from bottom to top in the stacking bin channel 31; the entire transfer and stacking process of the workpieces does not require human participation, thereby improving the yield rate and production efficiency.

[0032] like Figure 1 As shown, the frame 1 is provided with a controller 100, such as Fig.12 As shown, the feeding mechanism 2, the driving mechanism 4 and the material moving mechanism 5 are all electrically connected to the controller 100; the switches and action sequences of the feeding mechanism 2, the driving mechanism 4 and the material moving mechanism 5 are all automatically program-controlled by the controller 100. In a specific embodiment, the chip model used by the controller 100 is FX3U-32M.

[0033] like Figure 2 As shown, the feeding mechanism 2 includes a circular vibrating screen 21, and the circular vibrating screen 21 is electrically connected to the controller 100; after the staff pours a large number of workpieces into the circular vibrating screen 21, the circular vibrating screen 21 is started, and the workpieces move along the circular vibrating screen 21 to the discharge port 210 of the circular vibrating screen 21; and the workpieces are arranged by themselves during the movement. A plurality of leakage holes 211 are provided on the circular vibrating screen 21 near the discharge port 210, and the shape of the leakage holes 211 is the same as the shape of the reversely placed workpieces, and can only accommodate one workpiece to pass through. When the arranged workpieces move toward the discharge port 210, when the reversely placed workpieces move to the leakage holes 211 with the vibration of the circular vibrating screen 21, they can just leak out from the leakage holes 211 to ensure that the workpieces flowing out of the discharge port 210 are all forwardly arranged workpieces, so that the orientations of the stacked workpieces in the stacking bin 31 are the same, and there will be no forward and reverse staggered arrangement.

[0034] In a specific embodiment, the present invention stacks the special-shaped thin-sheet iron cores, and the cross section of the iron core is wedge-shaped, that is, one end of the iron core is narrow and the other end is wide; the direction toward the moving direction of the iron core on the feeding mechanism 2 is the front, and when a large number of iron cores are arranged and transported by the feeding mechanism 2, the iron cores with a narrow front end and a wide rear end are the forward iron cores, and the iron cores with a wide front end and a narrow rear end are the reverse iron cores; the shape of the leakage hole 211 is the same as the shape of the cross section of the iron core, and the wide end faces forward and the narrow end faces thick. When the reverse iron core moves to the leakage hole 211, it can leak out from the leakage hole 211 to ensure that only the forward iron core continues to be transmitted forward.

[0035] In the present invention, when workpieces of different colors need to be cross-stacked, two feeding mechanisms 2 are symmetrically arranged on the frame 1, and the material holding block 3 is located between the two feeding mechanisms 2; both feeding mechanisms 2 are electrically connected to the controller 100, and the controller 100 controls the material moving mechanism 5 to transfer the workpieces of different colors to the stacking bin 31 in the required stacking order according to the demand, thereby realizing the cross-stacking of workpieces of different colors. According to actual needs, when workpieces of three or more colors need to be cross-stacked, in the present invention, only a feeding mechanism 2 needs to be added to the frame 1, and each feeding mechanism 2 is corresponding to loading workpieces of one color, and the controller 100 controls the order in which the material moving mechanism 5 transfers the workpieces, thereby realizing the cross-stacking of workpieces of multiple colors.

[0036] like Figure 2 As shown, the feeding mechanism 2 also includes a straight vibrating screen 22, which is connected to the discharge port 210. The workpiece in the circular vibrating screen 21 is transferred from the discharge port 210 to the straight vibrating screen 22 and transferred forward in a straight line. The straight vibrating screen 22 is provided with a groove 221, and the length direction of the groove 221 is the same as the moving direction of the workpiece; the groove 221 is arranged along the moving path of the workpiece to reduce the contact area between the workpiece and the straight vibrating screen 22, and to prevent the workpiece coated with color coating from adhering to the straight vibrating screen 22. The circular vibrating screen 21 and the straight vibrating screen 22 are both electrically connected to the controller 100, and the controller 100 controls the feeding speed of the workpiece by controlling the switch and vibration speed of the circular vibrating screen 21 and the straight vibrating screen 22.

[0037] like Figure 2As shown, a fiber optic sensor 6 is provided on the straight vibrating screen 22 at the discharge port 210 close to the circular vibrating screen 21, and the fiber optic sensor 6 is electrically connected to the controller 100; the fiber optic sensor 6 is used to detect whether the workpiece has been staying at the position corresponding to the fiber optic sensor 6 on the straight vibrating screen 22. If so, it means that the workpieces on the straight vibrating screen 22 are too dense, and the controller 100 controls the circular vibrating screen 21 to stop to avoid congestion of workpieces on the straight vibrating screen 22.

[0038] like Figure 3 and Figure 4 As shown, a shielding device 7 and a reset mechanism 8 are provided on the frame 1, and the shielding device 7 is slidably connected to the frame 1; the shielding device 7 is located above the discharge port 220 of the feeding mechanism 2, and when the shielding device 7 slides relative to the frame 1, the shielding device 7 can shield the discharge port 220 from above the discharge port 220, or expose the discharge port 220.

[0039] The shielding device 7 is located on the moving path of the material moving mechanism 5, that is, the driving force for driving the shielding device 7 to move to expose the discharge port 220 in the present invention comes from the material moving mechanism 5, and there is no need to set up a separate driving device for the shielding device 7 to drive the material moving mechanism 5 to move, so that the structure of the stacking device is simplified. Initially, the shielding device 7 blocks the discharge port 220; when the material moving mechanism 5 moves to contact with the shielding device 7, the driving mechanism 4 continues to drive the material moving mechanism 5 to move, so that the material moving mechanism 5 pushes the shielding device 7 to move, thereby exposing the discharge port 220. When the material moving mechanism 5 grabs the workpiece from the discharge port 220 and transfers the workpiece to the material holding block 3, as the material moving mechanism 5 moves away from the shielding device 7, the reset mechanism 8 drives the shielding device 7 to reset and blocks the discharge port 220. When the material moving mechanism 5 is separated from the reset mechanism 8, the shielding device 7 blocks the discharge port 220.

[0040] like Figure 1 As shown, the driving mechanism 4 includes a first driver 41 and a second driver 42 arranged on the first driver 41; the first driver 41 drives the second driver 42 to perform linear reciprocating motion in a direction parallel to the arrangement direction of the loading mechanism 2 and the material holding block 3, and the second driver 42 is connected to the material moving mechanism 5 and drives the material moving mechanism 5 to move up and down.

[0041] Specifically, the first driver 41 drives the second driver 42 to move toward the direction of the straight vibration screen 22, and the material moving mechanism 5 moves toward the shielding device 7 until the material moving mechanism 5 contacts the shielding device 7 and pushes the shielding device 7 to expose the discharge port 220, then the first driver 41 stops, and the material moving mechanism 5 faces the discharge port 220; the second driver 42 drives the material moving mechanism 5 to move downward and grab / absorb the workpiece at the discharge port 220. The second driver 42 drives the material moving mechanism 5 to move upward, the first driver 41 drives the second driver 42 to move in a straight line toward the material holding block 3, the material moving mechanism 5 is separated from the shielding device 7, and the reset mechanism 8 drives the shielding device 7 to reset and shield the discharge port 220; when the material moving mechanism 5 moves to correspond to the stacking bin channel 31, the first driver 41 stops, and the second driver 42 drives the material moving mechanism 5 to move downward to send the workpiece into the stacking bin channel 31. After the workpieces are stacked in the stacking bin channel 31 , the second driver 42 drives the material moving mechanism 5 to move upward and leave the stacking bin channel 31 , waiting for the next transfer of the workpieces.

[0042] The sliding direction of the shielding device 7 is parallel to the moving direction of the material moving mechanism 5 under the driving action of the second driver 42, so as to ensure that the material moving mechanism 5 can push the shielding device 7 to expose the discharge port 220 during the movement.

[0043] like Figure 6 As shown, the first driver 41 includes a motor 411, a lead screw 412 connected to the rotating shaft of the motor 411, and a nut 413 sleeved on the lead screw 412, wherein the lead screw 412 is arranged horizontally and parallel to the arrangement direction of the feeding mechanism 2 and the material holding block 3; the second driver 42 is connected to the nut 413 so as to perform linear motion along the lead screw 412 under the drive of the nut 413. The second driver 42 includes a linear motor, which is respectively connected to the nut 413 and the material moving mechanism 5; the nut 413 drives the linear motor to perform linear motion, and the linear motor drives the material moving mechanism 5 to move up and down.

[0044] The sliding direction of the shielding device 7 is perpendicular to the groove 221; the sliding direction of the shielding device 7 is parallel to the arrangement direction of the feeding mechanism 2 and the material holding block 3. The reset mechanism 8 includes a block 81 provided on the frame 1, and a first elastic member 82 connecting the block 81 with the shielding device 7; the block 81 is used to fix the first elastic member 82 and ensure that the elastic expansion direction of the first elastic member 82 is parallel to the sliding direction of the shielding device 7. When the material moving mechanism 5 drives the shielding device 7 to slide, the shielding device 7 slides in the direction of the direct vibration screen 22 away from the material holding block 3. The first elastic member 82 is located at one end of the shielding device 7 away from the material holding block 3; when the first elastic member 82 is in a natural state, the shielding device 7 blocks the discharge port 220; when the material moving mechanism 5 contacts the shielding device 7 and continues to move toward the direction of the direct vibration screen 22 away from the material holding block 3, the first elastic member 82 is compressed to provide space for the movement of the shielding device 7 to expose the discharge port 220.

[0045] The shielding device 7 is used to shield at least two workpieces at the same time; Figure 3 and Figure 4 As shown, the shielding device 7 is provided with a notch 9 at one end close to the material holding block 3; the notch 9 is only for one workpiece to pass through. Figure 4 As shown, when the shielding device 7 blocks the discharge port 220, the arrangement direction of the projections of the notch 9 and the discharge port 220 on the same horizontal plane is parallel to the sliding direction of the shielding device 7, that is, the notch 9 and the discharge port 220 are misaligned with each other, and the notch 9 is located on the side of the discharge port 220 close to the material holding block 3; when the material moving mechanism 5 drives the shielding device 7 to slide in a direction away from the material holding block 3, the notch 9 also moves in a direction away from the material holding block 3; as shown in FIG. Figure 5 As shown, when the material moving mechanism 5 corresponds to the material outlet 220 , the notch 9 corresponds to the material outlet 220 , the first driver 41 stops, and the second driver 42 drives the material moving mechanism 5 to move downward.

[0046] The notch 9 is used to expose the first workpiece in the workpiece conveying direction among the several workpieces to be blocked, and to block the second workpiece or multiple workpieces that are simultaneously arranged after the first workpiece, so that the material transfer mechanism 5 can only transfer one workpiece at a time to avoid adhesion and overlap between workpieces. A cover plate 10 is provided on the straight vibration screen 22, and the cover plate 10 is located directly above the groove 221. There is a gap between the cover plate 10 and the straight vibration screen 22 for accommodating the workpiece, and the height of the gap can only accommodate one workpiece, thereby ensuring that the workpieces can be arranged in a straight line in sequence after entering the gap without adhesion and overlap. Furthermore, the cover plate 10 does not block the discharge port 220, and the shielding device 7 is arranged adjacent to the cover plate 10.

[0047] like Figure 3 As shown, the shielding device 7 includes a baffle 71 and a guide column 72, wherein the guide column 72 is vertically arranged and the baffle 71 is horizontally arranged; the width of the baffle 71 is greater than or equal to twice the width of the workpiece to ensure that the baffle 71 can shield at least two workpieces at the same time. The baffle 71 is connected to the guide column 72 and is slidably connected to the frame 1; the guide column 72 is located on the side of the straight vibration screen 22 away from the material holding block 3; the guide column 72 is located on the moving path of the material shifting mechanism 5; when the material shifting mechanism 5 contacts the guide column 72 and continues to move in the direction of the straight vibration screen 22 away from the material holding block 3, the guide column 72 drives the baffle 71 to slide under the driving force of the material shifting mechanism 5, so that the notch 9 corresponds to the discharge port 220, exposing the discharge port 220.

[0048] like Fig.11 As shown, a material lifting block 11 is provided in the stacking bin channel 31, and the cross section of the material lifting block 11 is the same as the cross section of the workpiece; the material lifting block 11 supports the workpiece from below to prevent the workpiece from tipping over when it is lowered and stacked in the stacking bin channel 31. A third driver is also provided on the frame 1, and the third driver is electrically connected to the controller 100; a portion of the third driver is inserted into the stacking bin channel 31 from the lower end opening of the stacking bin channel 31, and is connected to the material lifting block 11 to drive the material lifting block 11 to move up and down. The third driver includes a second linear motor; each time the material transfer mechanism 5 transfers a workpiece into the stacking bin channel 31, the third driver drives the material lifting block 11 to descend to the height of a workpiece, providing a stacking space for the next workpiece to enter the stacking bin channel 31.

[0049] like Figure 7As shown, the frame 1 is provided with a limit clamp 12, and the limit clamp 12 includes a first clamp arm 121 and a second clamp arm 122; there is an accommodation space 200 between the first clamp arm 121 and the second clamp arm 122, and the accommodation space 200 is located above the stacking bin channel 31 and communicated with the stacking bin channel 31; the accommodation space 200 is located on the moving path of the material moving mechanism 5, so that the material moving mechanism 5 can pass through the accommodation space 200 and enter the stacking bin channel 31. When the limit clamp 12 is opened, the width of the accommodation space 200 is greater than the width of the workpiece, and the material moving mechanism 5 can carry the workpiece into the stacking bin channel 31, and leave the workpiece in the stacking bin channel 31 to be gradually stacked. When the limit clamp 12 is closed, the width of the accommodating space 200 is smaller than the width of the workpiece, and the first clamping arm 121 and the second clamping arm 122 limit the workpiece from both sides of the material moving mechanism 5 and from above the workpiece, so that when the material moving mechanism 5 moves out of the stacking bin channel 31 through the accommodating space 200, the workpiece can remain in the stacking bin channel 31, and the workpiece will not be moved out of the stacking bin channel 31 together with the material moving mechanism 5 due to the viscosity of the color paint on the surface of the workpiece.

[0050] The first clamping arm 121 and the second clamping arm 122 are symmetrical to each other and are both rotatably connected to the frame 1; the first clamping arm 121 and the second clamping arm 122 are connected via a second elastic member 13; the second elastic member 13 is located at a side of the rotation connection point between the first clamping arm 121 and the frame 1 close to the stacking bin road 31; Figure 7 As shown, when the second elastic member 13 is in a natural state, the limit clamp 12 is opened, that is, when there is no external force acting on the limit clamp 12, the limit clamp 12 is in an open state in the natural state to ensure that the material moving mechanism 5 carrying the workpiece can smoothly pass through the accommodating space 200 and enter the stacking bin channel 31.

[0051] Since the first clamping arm 121 and the second clamping arm 122 are symmetrical to each other and constitute the limit clamp 12, when the second elastic member 13 is in a natural state, the limit clamp 12 is opened, that is, one end of the accommodating space 200 is wide and the other end is narrow, and the wide end of the accommodating space 200 faces the stacking bin channel 31.

[0052] like Figure 7As shown, the material moving mechanism 5 is provided with an insertion pin 14. When the material moving mechanism 5 passes through the accommodating space 200 and is inserted into the stacking bin channel 31, the insertion pin 14 is inserted into the accommodating space 200 from the narrow end of the accommodating space 200, and respectively supports the first clamping arm 121 and the second clamping arm 122, so that the narrow end of the accommodating space 200 becomes wider and the wide end of the accommodating space 200 becomes narrower, and the second elastic member 13 is compressed to reach the position where the accommodating space 200 is close to the material moving mechanism 5, so that the limit clamp 12 is closed, and the workpiece on the material moving mechanism 5 is limited to prevent the workpiece from moving out of the stacking bin channel 31 with the material moving mechanism 5.

[0053] When the insertion pin 14 is moved out of the accommodating space 200 , the limiting clip 12 is automatically reset to the open state under the elastic force of the second elastic member 13 .

[0054] like Figure 8 As shown, the insertion pin 14 includes an insertion pin body 141; the insertion pin body 141 is tapered at one end facing the limit clamp 12, i.e., the lower end of the insertion pin body 141, so that the lower end of the insertion pin body 141 gradually becomes thicker from bottom to top. The minimum width of the insertion pin body 141 is smaller than the minimum width of the accommodation space 200, so that when the limit clamp 12 is in an open state, the insertion pin body 141 can be inserted into the narrow end of the accommodation space 200; as the material shifting mechanism 5 moves downward, the insertion pin body 141 gradually moves downward in the accommodation space 200, and the portion of the insertion pin body 141 contacting the first clamping arm 121 and the second clamping arm 122 becomes wider and wider, so that the first clamping arm 121 and the second clamping arm 122 are supported to rotate relative to the frame 1, and the accommodation space 200 becomes narrower near the stacking bin 31, so that the closing of the limit clamp 12 is achieved.

[0055] like Figure 8As shown, the insertion pin 14 also includes a third elastic member 142 located above the insertion pin body 141, and the third elastic member 142 connects the insertion pin 14 with the material shifting mechanism 5; the third elastic member 142 elastically expands and contracts in the vertical up and down direction. The third elastic member 142 is used to delay the opening and closing of the limit clamp 12: when the material shifting mechanism 5 carries the workpiece to move toward the stacking bin channel 31 below, the insertion pin body 141 will first enter the accommodating space 200 and support the first clamping arm 121 and the second clamping arm 122, and the material shifting mechanism 5 continues to carry the insertion pin body 141 downward, and needs to overcome the elastic force of the third elastic member 142 to compress the third elastic member 142, thereby extending the length of time that the material shifting mechanism 5 stays in the stacking bin channel 31, ensuring that the workpiece can enter the stacking bin channel 31. When the material shifting mechanism 5 moves upward, the pin body 141 moves upward, and at the same time, the third elastic member 142 gradually recovers its elastic deformation. Only when the third elastic member 142 completely recovers its elastic deformation and the pin body 141 is separated from the accommodating space 200, can the limiting clamp 12 be reset to the open state; the third elastic member 142 delays the movement process of the pin body 141 separating from the accommodating space 200, so that when the material shifting mechanism 5 moves out of the stacking bin channel 31, the limiting clamp 12 is delayed in opening, thereby ensuring that the workpiece carried by the material shifting mechanism 5 can remain in the stacking bin channel 31, and will not stick to the material shifting mechanism 5 and move out of the stacking bin channel 31.

[0056] like Figure 8 As shown, the pin 14 also includes a first mounting portion 143 and a first limit block 144 arranged in the first mounting portion 143; the first mounting portion 143 is hollow and has openings at both ends, and the first limit block 144 blocks the opening at the upper end of the first mounting portion 143; the first mounting portion 143 is connected to the material moving mechanism 5, and the third elastic member 142 is located in the first mounting portion 143 and connected to the lower end of the first limit block 144; when the third elastic member 142 is in a natural state, one end of the pin body 141 is located in the first mounting portion 143 and connected to the third elastic member 142, and the other end is located outside the first mounting portion 143.

[0057] like Figure 7As shown, the material transfer mechanism 5 includes a first vertically arranged adapter plate 51, a second horizontally arranged adapter plate 52, and a suction nozzle 53. The second adapter plate 52 is connected to the lower end of the first adapter plate 51, and the upper end of the first adapter plate 51 is connected to the linear motor. Both ends of the second adapter plate 52 in the horizontal direction exceed the first adapter plate 51 and are respectively installed with the suction nozzle 53 and the pin 14. Both ends of the second adapter plate 52 parallel to the arrangement direction of the loading mechanism 2 and the material holding block 3 are at a certain distance from the suction nozzle 53. Preferably, the suction nozzle 53 is located at the center of the second adapter plate 52; the second adapter plate 52 can contact the shielding device 7 and drive the shielding device 7 to slide; when the second adapter plate 52 contacts the guide column 72, the distance between the suction nozzle 53 and the guide column 72 is greater than or equal to the width of the discharge port 220, so that when the notch 9 corresponds to the discharge port 220, the discharge port 220 is exposed, and the suction nozzle 53 can correspond to the discharge port 220.

[0058] The suction nozzle 53 is electrically connected to the controller 100, and the controller 100 controls the suction nozzle 53 to suck the workpiece or release the workpiece. Fig. 9 As shown, the suction nozzle 53 includes a second mounting portion 532 disposed on the second adapter plate 52, and a second stopper 533, a fourth elastic member 534 and a suction nozzle 535 connected in sequence from top to bottom; the second mounting portion 532 is a hollow structure and has openings at both ends; the second stopper 533 and the fourth elastic member 534 are both located in the second mounting portion 532, and when the fourth elastic member 534 is in a natural state, one end of the suction nozzle 535 is located in the second mounting portion 532 and connected to the fourth elastic member 534, and the other end is located outside the second mounting portion 532, so as to suck or release the workpiece. The fourth elastic member 534 provides a buffering effect for the suction nozzle 535 to prevent the suction nozzle 535 from dropping too much when sucking the workpiece, and from being squeezed and damaged by the workpiece. When the notch 9 corresponds to the discharge port 220, the suction nozzle 535 is located corresponding to the discharge port 220. The first elastic member 82 , the second elastic member 13 , the third elastic member 142 and the fourth elastic member 534 are all springs.

[0059] The second driver 42 is provided with a vacuum generator 531 (such as Figure 1 As shown), the vacuum generator 531 is connected to the controller 100 and the suction nozzle 535 respectively.
