Description

Technical Field

[0001] This invention relates to automated equipment, and more particularly to a semi-automatic O-ring assembly device. Background Technology

[0002] With the development of the times, industrial production technology is also developing rapidly, and automated equipment is being used more and more in industrial production. In order to ensure the sealing of mobile phone buttons during assembly, O-rings need to be fitted on the connecting posts of the button assembly. Currently, fitting O-rings on the connecting posts is usually done manually. However, because the connecting posts are thin, manual fitting of O-rings is not only inconvenient, but also easy to damage the connecting posts due to excessive force. Manual operation is not only costly, but also inefficient. It lacks competitiveness in the industrial field that emphasizes cost reduction and efficiency improvement, and is not conducive to large-scale promotion and industrialized production.

Driven by the linear movement mechanism, the button assembly moves downwards. The connecting post first passes through the guide hole and then extends into the sleeve. The guide hole provides guidance for the connecting post. Then, driven by the assembly mechanism, the O-ring detaches from the sleeve and is fitted onto the connecting post. The linear movement mechanism then drives the button assembly to reset, and the button assembly is removed. This process is repeated to assemble the O-ring. Since the assembly process is automated, manual loading and unloading are only required. This is more convenient than manual assembly and avoids the risk of damage to parts due to difficulty in controlling force during manual assembly, thus improving the yield rate and increasing the degree of automation.

In use, the button assembly 25 is first fixed to the fixing mechanism with the connecting post 26 of the button assembly 25 facing downwards. Then, the O-ring is fitted onto the outer wall of the sleeve 15. Driven by the linear motion mechanism 3, the button assembly 25 moves downwards. The connecting post 26 passes through the guide hole and then extends into the sleeve 15. The guide hole provides guidance for the connecting post 26. Then, driven by the assembly mechanism, the O-ring detaches from the sleeve 15 and fits onto the connecting post 26. The linear motion mechanism 3 then drives the button assembly 25 to reset, and the button assembly 25 is removed. This process is repeated to assemble the O-ring.

[0028] Optionally in this embodiment, the assembly mechanism includes a sleeve seat, a sleeve 15, a second cylinder 16, a collar, and a connecting plate 17. The sleeve seat is fixed to the top surface of the base 1 between two vertical plates 9. The sleeve 15 is vertically fixed to the sleeve seat. A guide plate 18 is provided on the top of the sleeve 15. The second cylinder 16 is fixed to the top surface of the base 1. The first end of the connecting plate 17 is fixed to the cylinder rod of the second cylinder 16. The collar is fixed to the second end of the connecting plate 17. The collar is slidably sleeved on the sleeve 15. The collar can move up and down under the drive of the second cylinder 16. The top end of the collar can press the O-ring sleeved on the sleeve 15. In this embodiment, the sleeve 15 is a hollow tube, and the number of guide plates 18 is greater than one and is spaced apart along the circumference of the sleeve 15. The connecting post 26 can extend into the sleeve 15. The guide plates 18 are elastic, which makes it convenient for the user to put the O-ring on the sleeve 15 through the guide plates 18. The collar squeezes the O-ring on the sleeve 15 from bottom to top. Under the compression of the collar, the O-ring is separated from the sleeve 15 and the guide plates 18 and puts on the connecting post 26 that extends into the sleeve 15.

[0029] Optionally, in this embodiment, three photoelectric sensors 19 are arranged at vertical intervals on the side wall of the electric lead screw, and a light-shielding plate 20 is arranged on the side wall of the fixed base 4. The light-shielding plate 20 can move back and forth in the vertical direction under the drive of the electric lead screw. Each photoelectric sensor 19 is provided with a detection end, and the end of the light-shielding plate 20 can extend into the detection end of any one of the photoelectric sensors 19. The three photoelectric sensors 19 can be used to control the movement of the first cylinder 14, the second cylinder 16, and the electric lead screw, respectively. In this embodiment, the first cylinder 14 controls the extension and retraction of the cylinder rod through a first solenoid valve, which is controlled to open and close by the photoelectric sensor 19 located in the middle. The second cylinder 16 controls the extension and retraction of the cylinder rod through a second solenoid valve, which is controlled to open and close by the photoelectric sensor 19 located at the bottom.

[0030] Optionally in this embodiment, an emergency stop button 21 and an indicator light 22 are provided on the front of the base 1, and a start button 23 is provided on each of the left and right sides of the top of the base 1.

[0031] Optionally in this embodiment, the pressure block 7 is made of an anti-static material, and its outer surface is covered with rubber. Making the pressure block 7 of an anti-static material can prevent static electricity from affecting the button assembly 25.

[0032] Optionally in this embodiment, a side plate 24 is fixed to the side wall of the slider 12, and the cylinder rod of the first cylinder 14 is fixed to the side plate 24.

[0033] Movement Process: First, place the button assembly 25 on the connecting platform. Then, move the connecting seat 6 to press the pressure block 7 onto the top of the button assembly 25 to fix it. Next, place the O-ring onto the sleeve 15. Then, the button assembly 25 moves downward under the drive of the electric screw until the connecting post 26 passes through the guide hole. In the initial state, the two guide blocks 13 are tightly pressed together, and the notches on the guide blocks 13 close together to form the guide hole. After the connecting post 26 passes through the guide hole, since the button assembly 25 and the connecting platform need to continue to descend, the guide blocks 13 will block the connecting platform. At this time, the light shield 20 just extends into the detection end of the photoelectric sensor 19 located in the middle. Then, the two guide blocks 13 move away from each other under the drive of the first cylinder 14, allowing the button assembly 25 and the connecting platform to continue to move downward. The space is made up so that the guide block 13 can provide guidance without affecting the movement of the connecting platform. Then the button assembly 25 continues to descend until the connecting post 26 extends into the sleeve 15. At this time, the light shield 20 just extends into the detection end of the photoelectric sensor 19 located at the bottom. Then the second cylinder 16 drives the collar to move upward and squeeze the O-ring sleeved on the sleeve 15. Under the compression of the collar, the O-ring is separated from the sleeve 15 and the guide plate 18 and sleeved on the connecting post 26. Then the button assembly 25 moves upward to reset under the drive of the electric screw until the light shield 20 extends into the detection end of the photoelectric sensor 19 located at the top. At this time, the electric screw stops moving. Then the button assembly 25 with the O-ring sleeved is manually removed. This process is repeated to achieve semi-automatic assembly of the O-ring.

[0034] Using the semi-automatic O-ring assembly equipment in this embodiment has the advantages of convenient assembly, high yield rate and high degree of automation.
