A pair of symmetrically distributed limiting pins 35 are provided on the left side of the edge of the first through hole 323. The limiting pins 35 are screws, which are screwed on the first mounting plate 32 to limit the outer ring of the bearing to be coaxial with the first through hole 323. The third cylinder 322 drives the outer ring push block 324 to push the outer ring of the bearing to the first through hole 323 through the first gap.

[0039] The inner ring storage barrel 331 is connected to the second mounting plate 33. The inner ring storage barrel 331 is fixedly connected to the second mounting plate 33 through a fixed bracket (not shown in the figure), so that a second gap 335 is formed between the bottom end of the inner ring storage barrel 331 and the second mounting plate.

The limiting nails 35 are used to limit the outer ring of the bearing to be coaxial with the second through hole 333. The fourth cylinder 332 drives the inner ring pushing block 334 to push the inner ring of the bearing to the second through hole 333 through the second gap.

[0040] A fifth cylinder 336 is provided at the lower end of the second mounting plate, and the rod end of the fifth cylinder is connected to a top plate 337 coaxially arranged with the second through hole 333, and the top plate 337 is clearance-matched with the second through hole 333. The fifth cylinder drives the top plate 337 to place the inner ring of the bearing on the upper outer ring of the bearing through the first and second through holes, so that the inner and outer rings of the bearing are coaxially matched.

[0041] In addition, a photoelectric sensor 34 is provided in the first and second gaps respectively, and the photoelectric sensor 34 is fixed on the corresponding fixing brackets respectively. The photoelectric sensor 34 is used to detect whether there is a bearing inner ring or a bearing outer ring in the area.

[0042] like Figure 6 As shown, the transfer device 4 includes a column 41, which is an aluminum profile, and the upper end is fixedly connected to the base platform 1 through the column bottom plate 47, and the top end is connected to the cover 48. A vertically running linear transmission mechanism 42 is connected to the column 41.

The electromagnet 45 is used to jointly adsorb the inner and outer rings of the assembled bearing. A pair of metal sensors 46 are also provided on the mounting seat 44. The installation position of the metal sensor 46 matches the position of the inner and outer rings of the bearing with adsorption, and is used to detect whether the inner and outer rings of the bearing are adsorbed.

[0043] like Figure 7 , Figure 8 As shown, the carrier 100 includes a carrier plate 102 made of pom (Saigang), and a pair of freely rotatable guide wheels 103 are respectively arranged on both sides of the carrier plate, and each pair of guide wheels 103 realizes the movement and guidance of the carrier 100 by rolling contact with the guide plate 23. An annular groove 104 and a circular groove 107 are respectively arranged on the upper end surface of the carrier plate 102, and the diameter of the annular groove 104 and the diameter of the circular groove 107 are the same as the outer ring of the bearing and can form a clearance positioning fit. A group of ball mounting holes 105 and lower retainer mounting holes 106 are arranged in the annular groove 104, and the group of ball mounting holes 105 and the lower retainer mounting holes 106 are uniformly distributed around the center of the annular groove 104; a group of protrusions 108 for fixing the upper retainer are arranged in the circular groove 107, and a group of protrusions 108 are uniformly distributed around the center of the circular groove 107; a metal top wire 109 and an RFID chip 101 for starting and ending position sensor detection are arranged on the lower end surface of the carrier plate 102. The metal top wire 109 is used as the identification point of the start and end position sensors; the RFID chip 101 cooperates with the RFID reader 28 , and when the carrier 100 moves, the RFID chip just passes above the RFID reader 28 .

[0044] The circuit module 8 is connected with the above-mentioned various sensors, RFID readers and various actuators, such as cylinder electromagnetic control, electromagnets, etc., which are all conventional technologies in the field and will not be described in detail here.

[0045] The operation process of this program:

[0046] 1. First, place an empty carrier 100 at the starting end of the conveying device 2. The conveying device 2 drives the carrier 100 to move forward. When the metal top wire 109 in the carrier 100 passes the starting position sensor 25, it is identified. After identification, the second cylinder 27 of the conveying device 2 pushes up the blocking plate 29 to prevent the carrier 100 from moving forward. When the carrier 100 is limited and does not move, the RFID reader 28 reads the content of the RFID chip in the upper carrier 100. At this time, the information content is empty. The first cylinder 24 in the conveying device 2 pushes up the limiting plate 26 to prevent other carriers 100 from moving forward.

[0047] 2. The bearing inner and outer ring assembly device 3 is running, the third cylinder 322 pushes the bearing outer ring to the first through hole 323 for positioning; the fourth cylinder 332 pushes the bearing inner ring to the second through hole 333 for positioning, and then the fifth cylinder 336 pushes the bearing inner ring up to the bearing outer ring to form a fit, and the third to fifth cylinders return to their positions to prepare for the next assembly.

[0048] 3. The transfer device 4 operates by combining the longitudinal movement of the linear transmission mechanism 42 and the movement of the slide cylinder 43 in the vertical plane, aligning the electromagnet 45 with the assembled inner and outer rings of the bearing and electromagnetically absorbing them, and then moving them into the annular groove 104 of the carrier 100, and the electromagnet 45 loses its magnetism and returns to the corresponding moving parts of the transfer device 4 separated from the inner and outer rings of the bearing. The RFID reader 28 writes the completion status of the inner and outer rings of the bearing into the RFID chip, wherein the content written by the RFID reader 28 is controlled by the PLC programming program of the circuit module 8.

[0049] 4. After the RFID reader 28 reads the information content of the RFID chip, the second cylinder 27 drives the blocking plate 29 to return to its original position, and the carrier 100 equipped with the inner and outer rings of the bearing continues to move. When passing the end position sensor 30, the first cylinder 24 drives the limit plate 26 to return to its original position, and the next empty carrier 100 moves forward, and the above steps are repeated.

[0050] The present invention can intuitively recognize the structural composition and production and assembly process of deep groove ball bearings, increase students' cognitive learning of circuit and gas circuit application, expand students' training content in RFID technology, PLC programming, industrial robot communication and other aspects, and can intuitively display teaching content, thereby enhancing students' learning interest and improving teaching quality.

[0051] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form; any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the above disclosed methods and technical contents without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of protection of the technical solution of the present invention.
