DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] like Figure 1-4 As shown, a marking device for manufacturing a motor stator core comprises:

[0028] The feeding channel comprises a marking portion 6, and the marking portion 6 is structurally divided into a horizontal connecting portion 62 arranged symmetrically about the center of a V-shaped protrusion 61, and the apex of the V-shaped protrusion 61 faces the conveying surface of the feeding channel;

[0029] The rotating wheel 11 is rotatably arranged below the marking part 6 , and the shifting plates 111 are arranged in a circular array thereon. The marking part 6 is provided with a through slot 8 for the shifting plates 111 to pass through.

[0030] Specifically, the feeding channel includes an upper material portion 5 and a lower material portion 7 respectively connected to two horizontal connecting portions 62, and the upper material portion 5 and the lower material portion 7 and the horizontal connecting portion 62 are located at an angle of 135° on the conveying surface. Figure 3 As shown, the motor stator core is placed in the loading part 5. Since the conveying surface of the loading part 5 is inclined at 135° to the conveying surface of the horizontal connecting part 62 located on the left side of the V-shaped protrusion 61, the motor stator core slides along the loading part 5 toward the marking part 6 due to its own gravity. After the motor stator core slides to the marking part 6 to complete the marking, it moves to the unloading part 7. Since the conveying surface of the unloading part 7 is inclined at 135° to the conveying surface of the horizontal connecting part 62 located on the right side of the V-shaped protrusion 61, the motor stator core continues to slide and be collected along the unloading part 7 after marking. No additional transmission mechanism and driving source are required to load and unload the motor stator core, which effectively simplifies the structure and reduces the manufacturing cost.

[0031] Furthermore, the motor stator core slides along the feeding portion 5 to the marking portion 6, such as Figure 3As shown, the paddle plate 111 on the left side blocks the first motor stator core in the feeding part 5, and drives the rotary wheel 11 to rotate clockwise at a preset angle, so that the paddle plate 111 that blocks the first motor stator core follows the rotation, thereby canceling the obstruction to the first motor stator core, so that the first motor stator core continues to slide. At the same time, the paddle plate 111 on the left side adjacent to the paddle plate 111 that initially blocks the motor stator core rotates synchronously to push the first motor stator core to move to the marking part 6, and blocks the second motor stator core in the feeding part 5. When the rotary wheel 11 stops rotating, the first motor stator core is just located between the two paddle plates 111, and automatic loading is completed.

[0032] Further, such as Figure 3 As shown, the middle part of the marking part 6 is a V-shaped protrusion 61. When the first motor stator core passes through the horizontal connecting part 62 on the left side of the V-shaped protrusion 61 and moves to the V-shaped protrusion 61 of the marking part 6, since the motor stator core itself is cylindrical, it will roll to the top of the V-shaped protrusion 61, thereby automatically positioning the first motor stator core. The structure is simple, and no additional driving mechanism is required to position the motor stator core, which effectively simplifies the structure and saves manufacturing costs.

[0033] Furthermore, the first motor stator core is clamped and fixed, and then the marking machine 2 on the upper side of the marking part 6 is started to mark the first motor stator core. After the marking is completed, the wheel 11 is driven to rotate clockwise at a preset angle again, so that the paddle 111 that blocks the second motor stator core rotates with the wheel 11 and passes through the through slot 8 opened in the middle of the marking part 6, thereby canceling the blocking of the second motor stator core by the paddle 111. At this time, the second motor stator core continues to move to the horizontal connecting part 62 on the left side of the V-shaped protrusion 61. At the same time, when the paddle 111 passes through the through slot 8 opened in the middle of the marking part 6, it pushes the marked first motor electronic core to move out of the V-shaped protrusion 61. The marked first motor electronic core passes through the horizontal connecting part 62 on the right side of the V-shaped protrusion 61 and enters the unloading part 7, and moves along the conveying surface of the unloading part 7 for unloading.

[0034] At the same time, another paddle 111 adjacent to and located on the left side of the paddle 111 rotates synchronously, and pushes the second motor stator core at the horizontal connecting portion 62 located on the left side of the V-shaped protrusion 61 to move to the apex of the V-shaped protrusion 61 for positioning, thereby completing the loading of the second motor stator core while completing the unloading of the first motor stator core, thereby realizing automatic loading and unloading, and making loading and unloading happen simultaneously, effectively saving loading and unloading time and improving processing efficiency.

[0035] In the above technology, by driving the rotating wheel 11 to rotate clockwise at a preset angle, the paddle plate 111 that blocks the first motor stator core follows the rotation, thereby canceling the obstruction to the first motor stator core, so that the first motor stator core continues to slide. At the same time, the paddle plate 111 on the left side adjacent to the paddle plate 111 that initially blocks the motor stator core rotates synchronously to push the first motor stator core to move to the marking portion 6, and blocks the second motor stator core, and then clamps and fixes the first motor stator core, and then marks the first motor stator core. After the marking is completed, the rotating wheel 11 is driven to rotate clockwise at a preset angle again, so that the paddle plate 111 that blocks the second motor stator core follows the rotating wheel 11 to rotate and passes through the through slot 8 opened in the middle of the marking portion 6, thereby canceling the obstruction of the paddle plate 111 to the second motor stator core. At this time, the second motor stator core continues to move To the horizontal connecting part 62 on the left side of the V-shaped protrusion 61, when the paddle plate 111 passes through the through slot 8 opened in the middle of the marking part 6, the first motor electronic core that has been marked is pushed to move out of the V-shaped protrusion 61 for unloading. At the same time, another paddle plate 111 adjacent to the above-mentioned paddle plate 111 and located on its left side rotates synchronously, and pushes the second motor stator core located at the horizontal connecting part 62 on the left side of the V-shaped protrusion 61 to move to the vertex of the V-shaped protrusion 61 for positioning, so that the loading of the second motor stator core is completed while the unloading of the first motor stator core is completed. Compared with the prior art, there is no need to control multiple blocking devices to load and unload the motor stator core. Only one driving source is needed to realize automatic loading and unloading of the motor stator core. The degree of automation is high, and loading and unloading are carried out simultaneously, which effectively saves the operation time of a single motor stator core and effectively improves work efficiency.

[0036] As a further embodiment provided by the present invention, the present invention further includes a motor 3 for driving the rotating wheel 11 to rotate.

[0037] Specifically, the motor 3 is started to rotate, thereby driving the rotating wheel 11 to rotate a predetermined angle through the rotating shaft 31 fixed at the output end of the motor 3, so as to realize the synchronous loading and unloading. Only one driving source is needed to realize the automatic loading and unloading of the motor stator core, with a high degree of automation, effectively simplifying the structure and saving production costs.

[0038] As a further embodiment provided by the present invention, it further comprises a clamping mechanism 9 arranged on the marking part 6, which comprises a clamping plate 92 arranged symmetrically.

[0039] Specifically, after the motor stator core enters the marking part 6 for positioning, the two clamping plates 92 symmetrically arranged on the marking part 6 are driven to move toward each other, thereby clamping and fixing the motor stator core.

[0040] As a further embodiment of the present invention, the present invention further includes a rubber pad 93 fixedly disposed on the clamping plate 92 .

[0041] Specifically, the friction between the clamping plate 92 and the motor stator core is increased by the rubber pad 93, so that the motor stator core is better clamped and the motor stator core is buffered and protected.

[0042] As a further embodiment of the present invention, the present invention further includes an L-shaped plate 91 fixedly disposed on the clamping plate 92 .

[0043] Specifically, the clamping plate 92 is driven to move by driving the L-shaped plate 91 .

[0044] As a further embodiment provided by the present invention, it further includes a first bevel gear 112 symmetrically arranged on the rotating wheel 11 .

[0045] Specifically, it also includes a second bevel gear 12 meshing with the first bevel gear 112. A fixed shaft is symmetrically arranged on the marking part 6, and the second bevel gear 12 is rotatably arranged on the fixed shaft. When the motor 3 drives the rotating wheel 11 to rotate clockwise by a preset angle, the first bevel gear 112 also rotates by a preset angle following the rotating wheel 11, thereby driving the second bevel gear 12 meshing with the first bevel gear 112 to rotate one circle.

[0046] As a further embodiment of the present invention, the invention further includes a connecting rod 10 hinged between the L-shaped plate 91 and the second bevel gear 12 .

[0047] Specifically, Figure 4 The two clamping plates 92 are in a clamping state. At this time, the first end of the connecting rod 10 (with Figure 4 As shown in the figure, the first end of the connecting rod 10 is an end hinged with the second bevel gear 12) and is located close to the rotating wheel 11. When the motor 3 drives the rotating wheel 11 to rotate clockwise by a preset angle, the first bevel gear 112 also rotates by a preset angle following the rotating wheel 11, thereby driving the second bevel gear 12 meshing with the first bevel gear 112 to rotate one circle. The clamping plate 92 has the following positions:

[0048] Initially, if Figure 4 As shown, the marking machine 2 completes marking the motor stator core. At this time, the first end of the connecting rod 10 is close to the rotating wheel 11, and the clamping plate 92 is in a clamping state.

[0049] After the marking is completed, the motor 3 is started to drive the rotating wheel 11 to rotate clockwise by half of the preset angle, and the dial plate 111 pushes the motor stator core after the marking to move, and gradually moves it out of the V-shaped protrusion 61 of the marking part 6. At the same time, the new motor stator core is synchronously moved to the horizontal connecting part 62 on the left side of the V-shaped protrusion 61. During the process, the first bevel gear 112 also rotates half of the preset angle with the rotating wheel 11. At this time, the second bevel gear 12 rotates 180°, and the first end position of the connecting rod 10 moves away from the rotating wheel 11. At the same time, during the rotation process, the connecting rod 10 pushes the L-shaped plate 91 hinged to its second end to move, thereby driving the clamping plate 92 to move away from the motor stator core. Figure 3 As shown, the motor stator core is located between the two shifting plates 111 and does not contact, and when the second bevel gear 12 starts to rotate, the clamping plate 92 has already released the clamping of the motor stator core, so when the shifting plate 111 pushes the motor stator core, the clamping plate 92 has already released the clamping of the motor stator core.

[0050] When the motor 3 drives the rotating wheel 11 to continue to rotate clockwise by a preset angle, during the process, the dial plate 111 pushes the marked motor stator core to move out of the marking part 6 and move along the unloading part 7, and the new motor stator core synchronously enters the vertex of the V-shaped protrusion 61 of the marking part 6 for positioning, and the first bevel gear 112 also rotates by a preset angle with the rotating wheel 11, and the second bevel gear 12 also rotates one circle with the first bevel gear 112, so that the first end of the connecting rod 10 returns to the initial position. During the process, the connecting rod 10 pulls the L-shaped plate 91 to move, thereby driving the clamping plate 92 to move in the direction close to the motor stator core. When the first bevel gear 112 also rotates by a preset angle with the rotating wheel 11, the clamping plate 92 just completes the clamping of the motor stator core, thereby realizing simultaneous loading, unloading and positioning and clamping of the motor stator core, thereby realizing continuous marking operation, effectively saving the marking time of a single motor stator core, and further improving work efficiency.

[0051] As a further embodiment of the present invention, it also includes a collecting tank 4 located at the discharge port of the discharge part 7 .

[0052] Specifically, the first motor electronic core that has been marked is unloaded along the conveying surface of the unloading portion 7 and enters the collecting trough 4 for collection.

[0053] Working principle: When in use, the motor stator core slides along the feeding part 5 to the marking part 6. Figure 3As shown, the paddle plate 111 on the left side blocks the first motor stator core in the feeding part 5, and drives the rotating wheel 11 to rotate clockwise at a preset angle, so that the paddle plate 111 that blocks the first motor stator core follows the rotation, thereby canceling the blocking of the first motor stator core, so that the first motor stator core continues to slide. At the same time, the paddle plate 111 on the left side adjacent to the paddle plate 111 that initially blocks the motor stator core rotates synchronously to push the first motor stator core to move to the marking part 6, and blocks the second motor stator core in the feeding part 5. When the rotating wheel 11 stops rotating, The first motor stator core is just located between the two dial plates 111, and the automatic loading is completed. The middle part of the marking part 6 is a V-shaped protrusion 61. When the first motor stator core passes through the horizontal connecting part 62 on the left side of the V-shaped protrusion 61 and moves to the V-shaped protrusion 61 of the marking part 6, since the motor stator core itself is cylindrical, it will roll to the top of the V-shaped protrusion 61, thereby automatically positioning the first motor stator core, and then clamping and fixing the first motor stator core, and then starting the marking machine 2 on the upper side of the marking part 6 to mark the first motor stator core. After marking is completed , the wheel 11 is driven to rotate clockwise by a preset angle again, so that the paddle 111 that blocks the second motor stator core rotates with the wheel 11 and passes through the through slot 8 opened in the middle of the marking part 6, thereby canceling the blocking of the second motor stator core by the paddle 111. At this time, the second motor stator core continues to move to the horizontal connecting portion 62 on the left side of the V-shaped protrusion 61. At the same time, when the paddle 111 passes through the through slot 8 opened in the middle of the marking part 6, it pushes the first motor electronic core that has been marked to move out of the V-shaped protrusion 61. The first motor electronic core that has been marked passes through the V-shaped protrusion The horizontal connecting portion 62 on the right side of the portion 61 enters the unloading portion 7 and moves along the conveying surface of the unloading portion 7 to unload the material. At the same time, another paddle 111 adjacent to the above-mentioned paddle 111 and located on its left side rotates synchronously and pushes the second motor stator core at the horizontal connecting portion 62 on the left side of the V-shaped protrusion 61 to move to the vertex of the V-shaped protrusion 61 for positioning, so that when the unloading of the first motor stator core is completed, the loading of the second motor stator core is completed, thereby realizing automatic loading and unloading, and loading and unloading are carried out simultaneously, effectively saving loading and unloading time and improving processing efficiency.

[0054] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
