[0079] Example 9: See Figure 2 and Figure 10 As shown, this embodiment is a further improvement based on embodiment four. Specifically, an auxiliary positioning unit 6 is provided on one side of the riveting unit 5 for precise positioning of the rotating disk 301.

[0080] The auxiliary positioning unit 6 includes a fourth mounting base 601 set on the workbench 7. A positioning rod 602 is set on the fourth mounting base 601.

[0082] Alternatively, a positioning groove can be made on the inner side of the first mounting slot 302 to accommodate the insertion of the positioning pin 604.

[0083] In this embodiment, an auxiliary positioning unit 6 is provided. The positioning rod 602 can be inserted into the corresponding positioning hole 308 on the rotating disk 301, and the positioning pin 604 can be inserted into the first mounting slot 302 on the rotating disk 301 to perform precise positioning of the rotating disk 301. This ensures that the skeleton 1 is accurately positioned in the rotating disk 301, improves the installation and riveting accuracy, and ensures product yield and consistency.

[0084] Example 10: Not shown in the figure. This example is a further improvement on Example 3. Specifically, the mechanism further includes a first vibratory plate for feeding the skeleton 1, which is connected to the first feeding channel 305 of the first positioning unit 3; the mechanism further includes a second vibratory plate for feeding the iron core 2, which is connected to the second feeding channel 307 of the second positioning unit 4.

[0085] In this embodiment, by setting a first vibratory feeder to feed material through the first feeding channel 305 and a second vibratory feeder to feed material through the second feeding channel 307, production efficiency is improved.

[0086] This organization also includes various sensors used for detection, all of which are existing technologies and will not be described in detail in this document.

[0087] Working principle: First, the structure is calibrated and each component is adjusted to its initial position. Then, the frame 1 is fed through the first vibratory feeder. The frame 1 enters one of the first mounting slots 302 of the rotary disk 301 through the first feeding channel 305 (in the initial state, the rotary disk 301 has one first mounting slot 302 corresponding to the first feeding channel 305). Then, the rotary disk 301 is rotated by a fixed angle so that the next first mounting slot 302 corresponds exactly to the first feeding channel 305, allowing the second frame 1 to be received. At the same time, the iron core 2 enters the slot 407 of the feeding plate 401 through the second feeding channel 307 via the second vibratory feeder, awaiting installation.

[0088] When the sensor at the first mounting position 302 detects the skeleton 1, the first clamping block 405 of the second positioning unit 4 moves down and the second clamping block 406 moves up to clamp and position the iron core 2. Then, the second mounting base 404, along with the feeding plate 401, the first clamping block 405, and the second clamping block 406, moves together to the back of the first mounting position 302 via the first linear cylinder 402 until the tube 201 of the iron core 2 is inserted into the connecting hole 105 of the skeleton 1.

[0089] Then, the rotating disk 301 rotates through a fixed angle again, so that the next first mounting slot 302 rotates to the position where the iron core 2 can be installed; at the same time, the structures of the second positioning unit 4 are reset, waiting for the next execution command.

[0090] When the second iron core 2 and the frame 1 are installed, the sensor detects the assembled previous frame 1, and the riveting head 501 of the riveting unit 5 rivets the frame 1 and the iron core 2. After the required riveting effect is achieved, the riveting unit 5 returns to its position.

[0091] Then, the rotary disk 301 rotates to a fixed angle again to unload and collect the pressed frame 1 and iron core 2. Each station can be set to perform synchronously.

[0092] The automatic positioning and riveting mechanism designed in this invention can automatically rivet the frame and the iron core by positioning the frame in the first mounting position of the first positioning unit and the iron core in the second mounting position of the second positioning unit. The iron core is fed to the first mounting position and installed into the frame by the feeding plate. Then, the riveting head of the riveting unit automatically rivets the frame and the iron core, reducing labor costs and increasing production efficiency. The use of multiple linear cylinders in conjunction with various precise feeding and installation positioning structures ensures installation accuracy. Furthermore, the auxiliary positioning unit can insert the positioning rod into the corresponding positioning hole on the rotating disk and insert the positioning pin into the first mounting position on the rotating disk to precisely position the rotating disk, ensuring accurate positioning of the frame within the rotating disk, improving installation and riveting accuracy, ensuring product yield, and maintaining product consistency.
