[0023] Please see Figure 1 and Figure 2 This embodiment provides a core riveting machine, including a machine base 10, a coil feeding belt 20 and a finished product unloading belt 30 disposed on the machine base 10, and an assembly table. The assembly table is provided with several jigs for fixing the coils. A coil transverse movement mechanism 40 is disposed on the machine base 10 and can adjust the direction of the coils. A core assembly mechanism 50 is disposed along the moving direction of the coil transverse movement mechanism 40 and intersects with the coil feeding belt 20. A yoke assembly mechanism 60 is disposed on the side of the core assembly mechanism 50 and can lift and rotate the yoke angle. A core riveting mechanism 70 is disposed on the side of the yoke assembly mechanism 60 and can position the coils. A dust blowing mechanism 80 is provided at the feeding end of the finished product unloading belt 30. The core assembly mechanism 50 and the yoke assembly mechanism 60 are disposed on the side of the assembly table and the coils are conveyed to the assembly table by the coil transverse movement mechanism 40.

[0024] The coil feeding conveyor belt 20, assembly table, coil traversing mechanism 40, core assembly mechanism 50, yoke assembly mechanism 60, core riveting mechanism 70, dust blowing mechanism 80, and finished product unloading conveyor belt 30 are sequentially arranged on the machine base 10 to achieve automated production assembly, greatly saving manual labor, reducing manufacturing costs, saving production space, and improving production efficiency and quality. It completes high-quality assembly line operation, significantly improving production efficiency, reducing worker labor intensity, improving product quality, and reducing production costs.

[0025] In this embodiment, please refer to Figure 3 The coil transverse movement mechanism 40 includes a transversely moving transplanting frame 41. The transplanting frame 41 is equipped with a lifting assembly 42 with shock-absorbing components around its perimeter. Several pneumatic grippers 43 are arranged side-by-side at the output end of the lifting assembly 42, and rotary clamping cylinders 44 are located at both ends of the output end of the lifting assembly 42. A longitudinal conveying cylinder 45, with its output end extending longitudinally, is located on the side of the lifting assembly 42, which is located on one side of the iron core riveting mechanism 70. One of the rotary clamping cylinders 44 is located at the output end of the longitudinal conveying cylinder 45. After riveting is completed, the coil... After the riveted finished product is gripped by the rotary clamping cylinder 44, it is then transported to the finished product unloading belt 30 by the longitudinal conveying cylinder 45. The transfer frame 41 drives the rotary clamping cylinder 44 on one side to move to the upper side of the coil loading belt 20. The lifting component 42 drives the rotary clamping cylinder 44 to move down, grab the coil, and transfer the product to the assembly table. The pneumatic gripper 43 is mainly used to transfer the coil on the assembly table to the iron core assembly mechanism 50 and the yoke assembly mechanism 60 to achieve automatic feeding, reduce personnel contact, and reduce product contamination.

[0026] Please see Figure 4 When the iron core assembly mechanism 50 is working, the iron core is conveyed by the iron core vibration feeding assembly 51 on the iron core assembly mechanism 50. A translation receiving assembly 52 is provided at the discharge end of the iron core vibration feeding assembly 51 to receive the iron core and push it horizontally to align with the coil on the assembly table. An iron core forward pushing assembly assembly 53 is provided on the side of the translation receiving assembly 52 aligned with the coil to assemble the iron core onto the coil. The iron core is pushed into the center hole of the coil by the iron core forward pushing assembly assembly 53 to achieve automated installation. It should be noted that, in order to ensure that the direction of the iron core flowing to the iron core translation receiving assembly 52 is consistent, ... The core forward pushing assembly 53 can assemble the core onto the coil. The translation receiving assembly 52 has a receiving block 54, and the receiving block 54 is provided with a bearing hole through which the core passes. The bearing hole is provided with a sensing groove 55. The core flowing from the core vibration feeding assembly 51 flows into the bearing hole and is sensed by the sensor through the sensing groove 55. This causes the core translation receiving assembly 52 to transport the core to the core forward pushing assembly 53. The core forward pushing assembly 53 is provided with a pin that passes through the bearing hole to push the core onto the coil. In addition, the sensor is located on the upper side of the sensing groove and is fixed by a fixing plate.

[0027] The coil with the assembled iron core is conveyed by the coil traversing mechanism 40 to the assembly table located at one end of the yoke assembly mechanism 60, where the yoke assembly mechanism 60 assembles the yoke onto the coil. Please refer to [link to relevant documentation]. Figure 5 The yoke assembly mechanism 60 includes a yoke vibrating feeding assembly 61 and a yoke lifting assembly 62 located at the discharge end of the yoke vibrating feeding assembly 61. A yoke adjusting assembly 63 is provided on one side of the yoke lifting assembly 62 for clamping the yoke and rotating it at a certain angle. A yoke forward pushing assembly assembly 64 is provided below the yoke adjusting assembly 63 to push the yoke adjusting assembly 63 closer to the assembly table and assemble the yoke onto the coil. When the yoke vibrating feeding assembly 61 conveys the yoke to the upper side of the yoke lifting assembly 62, the yoke lifting assembly 62 lifts the yoke to the same height as the coil assembly yoke on the assembly table. Then, the yoke adjusting assembly 63 clamps the yoke on the yoke lifting assembly 62 and adjusts the yoke to the correct assembly position. Finally, the yoke forward pushing assembly assembly 64 drives the yoke adjusting assembly 63 closer to the assembly table so that the yoke adjusting assembly 63 assembles the yoke onto the coil. After assembly, the assembly is completed and the yoke is reset.

[0028] The yoke adjustment assembly 63 includes a slide block 630 that slides on the yoke forward push assembly 64. A rotating shaft 631 is rotatably mounted on the slide block 630. A clamping cylinder 632 is mounted on the rotating shaft 631 at one end of the yoke lifting assembly 62. A gear 633 is mounted on the rotating shaft 631. A vertical push cylinder 634 with a rack at the output end that meshes with the gear 633 is mounted on the slide block 630.

[0029] The coil with the assembled yoke iron is conveyed by the coil lateral movement mechanism 40 to the core riveting mechanism 70. Please refer to [link / reference]. Figure 6 The core riveting mechanism 70 includes two symmetrically arranged core riveting components 71. A positioning clamp 72 is provided between the two core riveting components 71, and a power drive component 73 is provided at the bottom of the two core riveting components 71 to simultaneously drive the riveting pins in the two core riveting components 71 to press against each other. A positioning component 74 for positioning the coil is provided on the side of the positioning clamp 72. The coil is transported to the positioning clamp 72 by the coil transverse movement mechanism 40, and then the positioning component 74 positions and restricts the coil between the two core riveting components 71 to avoid the coil moving during riveting and ensure the stability of riveting. It should be noted that in this embodiment, the power drive component 73 is a lifting cylinder, and inclined sliders are provided on both sides of the output end of the lifting cylinder to push the riveting pins on the core riveting components 71 close to the coil on the positioning clamp 72 for riveting.

[0030] The aforementioned positioning component 74 includes a base 740 with a guide groove, a top block 741 slidably disposed in the guide groove, an inclined slider 742 that drives the top block 741 to approach the positioning fixture 72 and position the coil within the positioning fixture 72, and a first telescopic cylinder 743 that drives the inclined slider 742 to slide up and down. A compression spring is provided in the guide groove to push the top block 741 to reset. The inclined slider 742 is mounted on the side of the top block 741 via a mounting seat. The first telescopic cylinder 743 pushes the inclined slider 742 upward, causing one end of the inclined surface of the inclined slider 742 to gradually rise, so that the inclined slider 742 pushes the top block 741 closer to the positioning fixture 72, thereby positioning the coil with the top block 741.

[0031] To prevent burrs and dust from remaining on the finished product after riveting, a dust blowing mechanism 80 is installed at the feeding end of the finished product unloading belt 30. The dust blowing mechanism 80 can blow away burrs and dust to ensure the quality of the finished product. The dust blowing mechanism 80 includes a blowing plate on the finished product unloading belt 30, a dust collection pipe below the blowing plate, and a return assembly that pushes the finished product into the blowing plate. The blowing plate is equipped with multiple air pipe interfaces, and the return assembly is equipped with a push plate and a second telescopic cylinder that drives the push plate to move backward and push the material. The second telescopic cylinder drives the push plate to push the conveyed finished coil into the area below the blowing plate. The blowing plate blows air to remove burrs and dust from the finished coil, which are then sucked away by the dust collection pipe. A vacuum cleaner is installed at the end of the dust collection pipe. After dust removal, the previous coil is pushed out by the coil below the blowing plate by the push plate and squeezed into the finished product unloading belt 30.

[0032] In summary, the present invention, with its core assembly mechanism 50, yoke assembly mechanism 60, and core riveting mechanism 70 arranged sequentially along the moving direction of the coil transverse movement mechanism 40, coordinates their actions to achieve coil conveying. The core is inserted into the center hole of the coil, and the left and right yokes are inserted into the ends of the cores on both sides of the coil. Then, the left and right yokes are simultaneously riveted to the cores. Finally, the finished product is moved to the finished product unloading belt 30 and transported to the predetermined location. Therefore, it can realize the automatic assembly of the coil, yoke, and core, with each station working simultaneously to achieve automated production, effectively improving production efficiency and reducing the labor intensity of operators. On the other hand, all assembly processes are completed by machines, without being limited by the operator's skill level, resulting in better standardization of finished products and improving the yield rate. At the same time, a dust blowing mechanism 80 is set on the finished product unloading belt 30 to remove burrs and dust generated during assembly, improving product quality. Furthermore, the coil transverse movement mechanism 40 is designed to adjust the feeding and discharging directions, making it applicable to multiple products and highly practical.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
