Description

Technical Field

[0001] This utility model relates to an automatic assembly equipment for cylinder piston magnetic rings. Background Technology

[0002] Some cylinders require the installation of pistons and magnetic rings. During production, the magnetic ring needs to be fitted onto the piston. However, during assembly, the annular magnetic ring cannot be directly fitted onto the piston. It is necessary to first cut a slit in the magnetic ring, break it open, and then fit it onto the piston. After fitting, glue needs to be applied to the slit in the magnetic ring. Currently, manual assembly is usually used. First, the magnetic ring is cut on an ultrasonic cutting machine, then manually fitted onto the piston. After fitting, glue is applied on a dispensing machine, then spread evenly on a glue applicator, and finally pressed down on a clamping mechanism. After this entire process is completed, the ring is placed in a receiving box. This process is time-consuming, labor-intensive, and has low assembly efficiency. Utility Model Content

[0022] like Figure 4As shown, the magnetic ring opening and pushing mechanism 11 includes a first support frame 111, a second support frame 112, and a third support frame 113. A receiving platform 114 is fixed to the top of the first support frame 111, and the receiving platform 114 rests against the right side of the placement plate 32.

The fifth slide cylinder 118 and the sixth slide cylinder 119 control the finger at the lower end of the finger cylinder 11A to insert into the magnetic ring 30. The finger of the finger cylinder 11A opens, opening the magnetic ring 30. During the opening process, it pushes the two baffles 117 to move outward. At this time, the left end of the two baffles 117 will not block the magnetic ring 30. The seventh slide cylinder 11B controls the pusher plate 11C to move to the left. The pusher plate 11C pushes the magnetic ring 30 to the left, that is, pushes the magnetic ring 30 towards the placement plate 32. The magnetic ring 30 is aligned with the piston 20. During the pushing process, the opened magnetic ring 30 is put onto the piston 20.

[0023] like Figure 5 As shown, the rotary dispensing device 2 includes a rotary table 21, with multiple rotary alignment devices 22 fixed along the circumference of the outer edge of the rotary table 21. The rotary dispensing device 2 also includes a first visual inspection device 23, a dispensing machine 24, a glue applicator 25, and a second visual inspection device 26 distributed along the circumference of the outer edge of the rotary table 21. The second lateral moving robot 13 grasps the assembled piston 20 and magnetic ring 30, rotates the piston 20 and magnetic ring 30 90 degrees to stand them up, and places them on the rotary alignment device 22. After placing one, the rotary table 21 rotates one station.

[0024] like Figure 6As shown, the rotary alignment device 22 includes a workstation frame 221. The upper end of the workstation frame 221 has a feeding station 222. A motor 223 and an eighth slide cylinder 224 are fixed on the workstation frame 221. The output shaft of the motor 223 is connected to a friction wheel 225. The friction wheel 225 extends into the feeding station 222 and contacts the outer wall of the magnetic ring 30. An eighth slide 2241 is located outside the eighth slide cylinder 224. A connecting plate 22 is fixed to the top of the eighth slide 2241. 6. A ninth slide cylinder 227 is fixed to the upper end of the connecting plate 226. The ninth slide cylinder 227 has a ninth slide 2271. A pressure plate 228 for pressing the piston 20 is fixed to one end of the ninth slide 2271. Two tenth slide cylinders 229 are installed on the upper end of the workstation frame 221. Both tenth slide cylinders 229 have a tenth slide 2291. A pressure block 22A is fixed to the end of each of the two tenth slides 2291. The two pressure blocks 22A are located on both sides of the magnetic ring 30.

[0025] During operation, the first robotic arm 6 moves the piston 20 on the piston feeding frame 5 to the placement plate 32, and the second robotic arm 7 moves the magnetic ring 30 on the magnetic ring feeding turntable 4 to the cutting table 101. The ultrasonic cutting blade 103 cuts a slit in the magnetic ring 30. The slit magnetic ring 30 is then moved to the receiving table 114 by the first transverse robotic arm 12. The finger at the lower end of the finger cylinder 11A inserts into the magnetic ring 30 to open it. The pusher plate 11C pushes the magnetic ring 30 to the left, and the first pressure head 36 presses down on the piston 20. During the pushing process, the opened magnetic ring 30 is fitted onto the piston 20. The assembled piston 20 and magnetic ring 30 are placed on the feeding station 222 by the second transverse robotic arm 13. The turntable 21 rotates one station. The corresponding rotational alignment device 22 rotates to below the first visual inspection device 23. The first visual inspection device 23 is used to detect whether the cut of the magnetic ring 30 is facing upwards. If it is not facing upwards, the eighth slide cylinder 224 and the ninth slide cylinder 227 control the pressure plate 228 to press the piston 20. The motor 223 drives the friction wheel 225 to rotate, and the friction wheel 225 drives the magnetic ring 30 to rotate, so that the notch of the magnetic ring 30 faces upwards. The turntable 21 then rotates to another station, and the glue dispensing machine 24 applies glue to the notch of the magnetic ring 30. The turntable 21 then rotates to another station, and the glue spreading machine 25 spreads the glue evenly. The turntable 21 then rotates to another station, and the second visual inspection device 26 detects whether the glue is firmly attached to the magnetic ring 30. The turntable 21 then rotates to another station, and the transfer robot 14 moves the piston 20 and the magnetic ring 30 to the discharge table 15. Finally, the third robot 9 places the product into the receiving box 8.

[0026] The present invention provides an automatic assembly equipment for cylinder piston magnetic rings, in which piston 20 and magnetic ring 30 can be automatically assembled together and glued. It has a high degree of automation, saves time and labor, and improves assembly efficiency.
