A slide 3 11 is fixedly installed in the middle of the front of the slide bed of the solenoid valve 10. An electric cylinder 12 is fixedly installed in the middle of the front of the slide bed of the slide 3 11. A cross block 13 is fixedly installed on the bottom surface of the telescopic end of the electric cylinder 12. A connecting block 14 is fixedly installed on the bottom of the front of the cross block 13. The right side of the front of the connecting block 14 is penetrated A glue injection head 15 is passed through and fixedly installed, and the top of the outer wall of the glue injection head 15 is fixedly connected to the second hose of the solenoid valve 10. A T-shaped tube 16 is passed through and fixedly installed on the left side of the front of the connecting block 14. A thin rod 17 is fixedly installed on the inner wall of the T-shaped tube 16, and a plate 18 is fixedly installed on the bottom of the outer wall of the thin rod 17. The thin rod 17 and the glue injection head 15 are in an inverted eight-shaped shape, and a chamfer is provided on the side of the plate 18 away from the thin rod 17. When the glue injection head 15 dispenses glue to the magnetic circle, the chamfer of the plate 18 evens out the glue on the edge of the magnetic circle, so that the glue on the edge of the magnetic circle can be smoother during the dispensing process, so as to avoid the uneven glue on the edge of the magnetic circle when the dispensing machine dispenses glue to the magnetic circle, resulting in poor dispensing quality of the edge of the magnetic circle;

[0033] A smoothing component is arranged on the left side of the front face of the connecting block 14, and the smoothing component includes an L-shaped plate 19, which is fixed on the left side of the front face of the connecting block 14, and is located behind the glue injection head 15. A circular shaft 20 is rotatably installed on the bottom of the outer wall of the L-shaped plate 19, and a circular roller 21 is fixedly installed on the right side of the outer wall of the circular shaft 20, and the circular roller 21 is located on the side of the circular shaft 20 away from the L-shaped plate 19, and the bottom of the circular roller 21 and the bottom of the sheet 18 are arranged in a horizontal state, and the circular roller 21 rotates on the magnetic ring, and the circular roller 21 sweeps out foreign matter accumulated on the magnetic ring, so that there is no accumulation on the surface of the magnetic ring, so as to avoid the accumulation of foreign matter on the surface of the magnetic ring when the glue dispensing machine is in use, causing the magnetic ring to be unqualified for glue coating.

[0034] When in use, the bottom plate 1 supports the turntable 2, the bottom plate 1 supports the glue dispenser 3, the bottom plate 1 supports the power supply 4, the staff puts the magnetic ring on the tray on the turntable 2, and uses the glue dispenser 3 to start the motor in the turntable 2, the motor shaft starts to rotate forward, the motor shaft drives the tray to rotate forward, and the tray drives the magnetic ring to rotate forward. Because the equipment is in the process of dispensing glue on the magnetic ring, the colloid on the edge of the magnetic ring is easy to be unevenly smeared. At this time, the bottom plate 1 supports the slide 1 5, the slide 1 5 supports the round rod 8, the round rod 8 supports the slide 2 9, the slide 2 9 supports the solenoid valve 10, the slide 2 9 supports the slide 3 11, and the slide 3 11 supports the electric cylinder 12. The staff can accurately adjust the position of the electric cylinder 12 through multiple slide structures to dispense glue on magnetic rings of different sizes. At the same time, the staff uses the control panel of the glue dispenser 3 to start the electric cylinder 12, and the telescopic end of the electric cylinder 12 starts to move downward, the telescopic end of the electric cylinder 12 drives the cross block 13 to move downward, and the cross block 13 drives the connecting block 14 downward The connecting block 14 drives the glue injection head 15 to move downward, and the glue injection head 15 moves downward to above the magnetic circle. At the same time, the solenoid valve 10 is started, and the solenoid valve 10 sucks the glue in the glue dispenser 3. The hose 1 of the solenoid valve 10 sucks the glue, and the hose 2 of the solenoid valve 10 transports the glue into the glue injection head 15. The glue injection head 15 dispenses glue on the positively rotating magnetic circle. When the horizontal block 13 drives the connecting block 14 to move downward, the connecting block 14 drives the T-shaped tube 16 to move downward, and the T-shaped tube 16 drives the thin rod 1 7 moves downward, and the thin rod 17 drives the plate 18 to move downward, and the plate 18 stays above the magnetic circle which is rotating forward, so that when the glue injection head 15 dispenses glue to the magnetic circle, the chamfer of the plate 18 can evenly spread the glue on the edge of the magnetic circle, so that the glue on the edge of the magnetic circle can be smoother during the dispensing process, thereby preventing the glue on the edge of the magnetic circle from being uneven when the equipment is in use, thereby avoiding the problem of poor glue dispensing quality on the edge of the magnetic circle caused by uneven glue on the edge of the magnetic circle when the glue dispenser dispenses glue to the magnetic circle.

[0035] While the horizontal block 13 drives the connecting block 14 to move downward, the connecting block 14 drives the L-shaped plate 19 to move downward, the L-shaped plate 19 drives the round shaft 20 to move downward, and the round shaft 20 drives the round roller 21 to move downward. In the process of the round roller 21 moving downward, the round roller 21 contacts the magnetic ring that is rotating forward. Under the action of friction, the round roller 21 rotates on the magnetic ring, so that the round roller 21 sweeps out the foreign matter accumulated on the magnetic ring, leaving no accumulation on the surface of the magnetic ring, thereby preventing foreign matter from accumulating on the surface of the magnetic ring when the equipment is in use, thereby avoiding the problem of unqualified gluing of the magnetic ring caused by foreign matter accumulating on the surface of the magnetic ring when the glue dispenser is in use.

[0036] See also Figure 1-Figure 9On the basis of the above embodiment, in another embodiment of the present invention, an anti-shake device 6 is provided on the top surface of the L-shaped plate 19, and the anti-shake device 6 includes a horizontal strip 61, two L-shaped rods 62, two H-shaped strips 63 and two sliders 64. The horizontal strip 61 passes through and is fixedly installed on the top surface of the L-shaped plate 19, the two L-shaped rods 62 are fixed on both sides of the top surface of the horizontal strip 61, the two H-shaped strips 63 are respectively fixed on the left and right sides of the electric cylinder 12, and the two sliders 64 are fixed on one end of the two L-shaped rods 62 away from the horizontal strip 61. The inner walls of the two sliders 64 are slidably connected with the outer walls of the two H-shaped strips 63. Sliding holes are opened on the bottom surfaces of the two sliders 64. The two L-shaped rods 62 are located on the front of the electric cylinder 12, and the H-shaped strip 63 limits the slider 64 to reduce the violent shaking of the connecting block 14 during the downward movement of the connecting block 14, so as to avoid the violent shaking of the connecting block 14 when the dispensing machine dispenses glue to the magnetic ring, causing the initial dispensing of the equipment to be offset.

[0037] The anti-shake device 6 also includes two short rods 65, two springs 66 and two blocks 67. The two short rods 65 are slidably installed on the inner walls of the sliding holes of the two sliders 64. The two springs 66 are fixed on the bottom surfaces of the two sliders 64. The two blocks 67 are respectively fixed on the bottom of the side of the two H-shaped blocks 63 away from each other. The top surfaces of the two H-shaped blocks 63 are fixedly connected to the bottom surfaces of the two short rods 65. The ends of the two springs 66 away from the two sliders 64 are respectively fixed on the top surfaces of the two blocks 67. The two springs 66 are sleeved on the outer walls of the two short rods 65. The elastic force of the springs 66 limits the downward movement distance of the slider 64, so that the downward moving glue head 15 will not contact the magnetic ring, thereby avoiding the glue injection head 15 from contacting the magnetic ring when the glue dispensing machine dispenses glue on the magnetic ring, causing damage to the glue injection head 15.

[0038] An anti-loosening device 7 is provided on the side where the anti-shake device 6 is away from each other. The anti-loosening device 7 includes two short plates 71, two round-headed rods 72, two arc blocks 73, four arc-shaped spring pieces 74 and two arc plates 75. The two short plates 71 are respectively fixed on the side where the two sliders 64 are away from each other, the two round-headed rods 72 are respectively fixed on the bottom surfaces of the two short plates 71, the two arc blocks 73 are respectively fixed on the side where the two blocks 67 are away from each other, the four arc-shaped spring pieces 74 are respectively fixed on the side where the two arc blocks 73 are away from each other, and the two arc plates 75 are respectively fixed on the side where the four arc-shaped spring pieces 74 are away from each other. The two arc plates 75 are respectively located on the movement trajectories of the two round-headed rods 72. Under the elastic force of the arc-shaped spring pieces 74, the arc plates 75 are tightly pressed against the round-headed rods 72, so that the arc plates 75 limit the displacement of the round-headed rods 72, thereby avoiding the glue dispensing vibration of the glue injection head 15 caused by the loose structure in the equipment when the glue dispensing machine dispenses glue to the magnetic ring.

[0039] The anti-loosening device 7 also includes two strip blocks 76, two elastic strips 77 and two rubber rings 78. The two strip blocks 76 are fixed on the bottom surfaces of the two short plates 71. The two strip blocks 76 are respectively located on the side of the two round-headed rods 72 away from each other. The two elastic strips 77 are respectively embedded in the bottom surfaces of the two strip blocks 76. The two rubber rings 78 are fixed at one end of the two elastic strips 77 away from the two strip blocks 76. The inner walls of the two rubber rings 78 are slidably connected to the outer walls of the two round-headed rods 72. The two arc blocks 73 are respectively on the movement trajectories of the two rubber rings 78. Under the elastic force of the elastic strips 77, the rubber rings 78 are against the arc blocks 73 to reduce the collision of the arc blocks 73, so as to avoid the parts in the equipment being hit when the glue dispenser dispenses glue on the magnetic ring, thereby shortening the service life of the equipment.

[0040] When the connecting block 14 drives the L-shaped plate 19 to move downward, the L-shaped plate 19 drives the horizontal plate 61 to move downward, the horizontal plate 61 drives the L-shaped rod 62 to move downward, the L-shaped rod 62 drives the slider 64, the slider 64 slides downward on the H-shaped bar 63, the H-shaped bar 63 limits the slider 64, the slider 64 limits the L-shaped rod 62, the L-shaped rod 62 limits the horizontal plate 61, the horizontal plate 61 limits the L-shaped plate 19, and the L-shaped plate 19 limits the connecting block 14, thereby reducing the violent shaking of the connecting block 14 during the downward movement of the connecting block 14, thereby avoiding the problem of the initial dispensing of the equipment caused by the violent shaking of the connecting block 14 when the glue dispensing machine dispenses glue to the magnetic ring.

[0041] When the slider 64 slides downward on the H-shaped bar 63, the H-shaped bar 63 supports the block 67, the block 67 supports the short rod 65, and the slider 64 slides downward on the short rod 65, the slider 64 drives the spring 66 to move downward, and the spring 66 begins to shrink. Under the elastic force of the spring 66, the elastic force of the spring 66 limits the downward movement distance of the slider 64. Under the elastic force limitation of the spring 66, the downward moving glue head 15 will not contact the magnetic ring, preventing the glue head 15 from contacting the rotating magnetic ring when the equipment is in use, thereby avoiding the problem of the glue head 15 contacting the magnetic ring when the glue dispensing machine dispenses glue to the magnetic ring, causing damage to the glue head 15.

[0042] When the slider 64 slides downward on the H-shaped bar 63, the slider 64 drives the short plate 71 to move downward, and the short plate 71 drives the round head rod 72 to move downward. At the same time, the block 67 supports the arc block 73, the arc block 73 supports the arc spring piece 74, and the arc spring piece 74 supports the arc plate 75. In the process of the short plate 71 moving downward, the short plate 71 contacts the arc plate 75, and the arc spring piece 74 is deformed. Under the elastic force of the arc spring piece 74, the arc plate 75 is tightly pressed against the round head rod 72, so that the arc plate 75 limits the displacement of the round head rod 72, preventing the structure in the device from loosening when the device is in use, thereby avoiding the problem of the glue injection head 15 vibrating due to the loose structure in the device when the glue dispensing machine dispenses glue to the magnetic ring.

[0043] When the slider 64 drives the short plate 71 to move downward, the short plate 71 drives the strip block 76 to move downward, the strip block 76 drives the elastic strip 77 to move downward, and the elastic strip 77 drives the rubber ring 78 to move downward. In the process of the rubber ring 78 moving downward, the rubber ring 78 contacts the arc block 73. Under the action of the extrusion force, the rubber ring 78 slides upward on the round head rod 72, and the elastic strip 77 on the rubber ring 78 begins to deform. Under the elastic force of the elastic strip 77, the rubber ring 78 is pressed against the arc block 73, reducing the arc block 73 from being bumped, thereby avoiding the problem of shortening the service life of the equipment due to the bumping of the parts in the equipment when the glue dispenser dispenses glue to the magnetic ring.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
