Description

Technical Field

[0001] This utility model relates to the field of rubber ring assembly technology, and in particular to a rotary automatic rubber ring pushing mechanism. Background Technology

[0002] In industrial production, rubber rings are widely used as important sealing elements in numerous fields such as automobile manufacturing, home appliance production, electronic equipment, and medical devices. For example, rubber rings are extensively used in automobile engines, transmissions, and braking systems to prevent leaks of lubricating oil, coolant, brake fluid, etc.; in home appliances, rubber rings are also needed at pipe connections in washing machines, air conditioners, refrigerators, and other equipment to ensure sealing performance and prevent water and air leaks. Therefore, the assembly quality of rubber rings directly affects the performance and reliability of the product. Rubber ring assembly is a crucial process in the production of rubber products and the sealing installation of mechanical parts.

[0003] However, in the current technology, most companies still use manual assembly, pushing rubber rings into the target workstations (such as shafts, holes, grooves, etc.). This manual assembly method has many disadvantages: First, it is inefficient, as the speed of manual operation is limited and it is difficult to meet the needs of mass production; second, the workload is large, and long-term repetitive labor can easily lead to worker fatigue and increase labor intensity; third, the error rate is high, as manual operation is affected by subjective factors and fatigue, and it is easy for rubber rings to be missed, misinstalled, or not properly assembled, resulting in an increase in product defect rate, increasing production costs and after-sales maintenance costs. In addition, with the continuous rise in labor costs, the economic benefits of manual assembly are gradually decreasing. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figure 1-5 As shown, this utility model provides a rotary rubber ring automatic push-in mechanism, including a mounting plate 1, a support base 11 and a round shaft base 14. Four sets of connecting rods 13 are fixedly installed on the upper end of the mounting plate 1, a push-in structure 2 is provided on the upper end of the mounting plate 1, and an installation structure 3 is installed on the upper end of the mounting plate 1.

[0026] The push-in structure 2 includes a servo motor 21, a drive shaft 22 rotatably mounted inside the round shaft seat 14, a turntable 23 fixedly mounted on the upper end of the drive shaft 22, four sets of material drop seats 24 fixedly mounted on the upper end of the turntable 23, two sets of No. 1 holes 25 penetrating through the lower end of the turntable 23 and corresponding to the lower part of the material drop seats 24, a support frame plate 26 fixedly mounted on one end of the mounting plate 1, a push-in cylinder 27 fixedly mounted on one side of the support frame plate 26, and two sets of push-in rods 28 fixedly mounted on the extended end of the push-in cylinder 27. A fixing plate 29 is fixedly installed on the outer wall of the round shaft seat 14. Two sets of No. 2 holes 210 are opened through the upper end of the fixing plate 29. The upper end of the servo motor 21 is fixed to the lower end of the mounting plate 1. The lower end of the transmission shaft 22 passes through the upper end of the mounting plate 1 and is fixed to the output end of the servo motor 21. The upper parts of the two sets of push rods 28 are respectively set inside the two sets of No. 2 holes 210. The support seat 11 is located on one side of the mounting plate 1. The round shaft seat 14 is located between the mounting plate 1 and the turntable 23.

[0027] The specific setup and function of this embodiment are described in detail below. A servo motor 21 is installed at the lower end of the mounting plate 1. A transmission shaft 22 is rotatably installed inside the round shaft seat 14, with the lower end of the transmission shaft 22 penetrating through the upper end of the mounting plate 1 and connected to the output end of the servo motor 21. A turntable 23 is installed at the upper end of the transmission shaft 22, and four sets of material drop seats 24 are installed on the upper end of the turntable 23. Eight sets of No. 1 holes 25 are opened through the lower end of the turntable 23, with each pair of No. 1 holes 25 corresponding to one set of material drop seats 24. A support frame plate 26 is installed at one end of the mounting plate 1, and a push-in cylinder 27 is installed on one side of the support frame plate 26. Two sets of push-in rods 28 are installed at the extended end of the push-in cylinder 27. A fixing plate 29 is installed on the outer wall of the round shaft seat 14, and two sets of No. 2 holes 210 are opened through the lower end of the fixing plate 29. When the rubber ring material falls into the interior of one set of material drop seats 24, the servo motor 21 is activated, and the servo motor 21 drives the transmission... Shaft 22 drives turntable 23 to rotate 90°, causing the rubber ring material to fall into another set of material drop seats 24. The above steps are repeated, rotating turntable 23 90°. At this time, the first set of material drop seats 24 containing rubber ring material can be moved above the fixed plate 29. Then, the push cylinder 27 is controlled to run. The movable end of the push cylinder 27 will push two sets of push rods 28 upward. The two sets of push rods 28 are respectively inserted into the corresponding two sets of first holes 25 and two sets of second holes 210, and then into the inside of the material drop seats 24, pushing out the rubber ring material inside the material drop seats 24. This pushes the rubber ring material into another material inside the assembly equipment, thereby realizing automatic assembly. The automation process replaces the original manual operation, reduces the workload of operators, greatly shortens the work cycle, improves work efficiency, and reduces production costs.

[0028] Example 2: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a control module 12 is fixedly installed on one side of the mounting plate 1. Two sets of No. 1 laser sensors 15 are fixedly installed on the upper end of the turntable 23. Two sets of No. 2 laser sensors 16 are fixedly installed on the upper end of the support base 11. An upper contact sensor 17 is installed through the lower end of the fixing plate 29. A lower contact sensor 18 is installed through the upper end of the support frame plate 26. The servo motor 21 and the push cylinder 27 are both electrically connected to the control module 12. The two sets of No. 1 laser sensors 15 and the two sets of No. 2 laser sensors 16 are all electrically connected to the control module 12, as are the upper contact sensor 17 and the lower contact sensor 18.

[0029] The overall effect of this embodiment is as follows: the rubber ring material photoelectric detection device has two sets of No. 1 laser sensors 15 symmetrically installed on the upper end of the turntable 23, and two sets of No. 2 laser sensors 16 installed at the corresponding positions on the upper end of the support base 11. The No. 1 laser sensor 15 emits a laser beam, and the No. 2 laser sensor 16 receives the laser signal. When the material drop seat 24 rotates to the detection area and contains rubber ring material, the laser beam is blocked, triggering the sensor to send a material presence signal to the control module 12.

[0030] Push-in stroke detection device: An upper contact sensor 17 is installed through the lower end face of the fixed plate 29, and a lower contact sensor 18 is installed through the upper end face of the support plate 26. Both the upper contact sensor 17 and the lower contact sensor 18 are proximity switch type sensors used to detect the position of the moving end of the push-in cylinder 27.

[0031] The control module 12 is fixedly installed at one end of the mounting plate 1. The control module 12 adopts a Siemens S7-1200 series PLC controller. Its input terminals are electrically connected to two sets of No. 1 laser sensors 15, two sets of No. 2 laser sensors 16, upper contact sensor 17 and lower contact sensor 18 respectively. Its output terminals are electrically connected to the drive controllers of servo motor 21 and push cylinder 27 respectively.

[0032] Rubber ring material inspection and 23-point rotary table:

[0033] When the turntable 23 rotates to the feeding station, the feeding equipment will transport the rubber ring into the dropping seat 24;

[0034] Two sets of No. 1 laser sensors 15 and two sets of No. 2 laser sensors 16 form a beam detection area. When the rubber ring material falls completely into the material drop seat 24, the laser beam is blocked and the sensor sends a high-level signal to the control module 12.

[0035] After receiving the signal, the control module 12 drives the servo motor 21 to run, and drives the turntable 23 to rotate 90° clockwise through the transmission shaft 22, so that the material drop seat 24 containing the rubber ring material moves to the push-in station.

[0036] Pushing action control: When the material drop seat 24 reaches the pushing position, the control module 12 drives the pushing cylinder 27 to extend and push the two sets of pushing rods 28 to move upward.

[0037] When the movable end of the push cylinder 27 approaches the upper contact sensor 17, the upper contact sensor 17 is triggered and sends a signal to the control module 12. The control module 12 immediately controls the push cylinder 27 to stop extending and switch to retraction.

[0038] The push cylinder 27 drives the two sets of push rods 28 to move downward. When the movable end approaches the lower contact sensor 18, the lower contact sensor 18 is triggered and sends a signal. The control module 12 controls the push cylinder 27 to stop running, completing one push cycle.

[0039] Intelligent error prevention system: The control module 12 has a built-in material counting program. By performing logical judgment on the signals of the first laser sensor 15 and the second laser sensor 16, if no material is detected for two consecutive detection cycles, or if multiple material signals are detected at a single station, an alarm is immediately triggered and the machine is stopped.

[0040] Fault self-diagnosis function: The control module 12 monitors the signal status of the upper contact sensor 17 and the lower contact sensor 18 in real time. If the corresponding sensor signal is not received within a specified time, it will automatically determine that the mechanical jamming or sensor failure is caused, and immediately stop the machine and display the fault code.

[0041] Example 3: Figure 1 and Figure 5 As shown, the mounting structure 3 includes two sets of stabilizing seats 31. A convex sliding plate 32 is slidably mounted on the outer wall of each pair of connecting rods 13. Two sets of telescopic rods 33 are installed through the upper ends of both sets of stabilizing seats 31. A micro motor 34 is installed through the upper ends of both sets of convex sliding plates 32. A rotating rod 36 is fixedly mounted on the output end of both sets of micro motors 34. An elliptical plate 35 is fixedly mounted on the upper end of both sets of rotating rods 36. The lower ends of both sets of stabilizing seats 31 are fixed to the upper end of the mounting plate 1.

[0042] The overall effect of this embodiment is as follows: four sets of connecting rods 13 are installed on the upper end of the mounting plate 1; two sets of stabilizing seats 31 are installed on the upper end of the mounting plate 1; two sets of telescopic rods 33 are installed through the upper end of each set of stabilizing seats 31; convex sliding plates 32 are slidably installed on the outer wall of each pair of connecting rods 13; micro motors 34 are installed through the upper end of each set of convex sliding plates 32; rotating rods 36 are fixedly installed at the output end of each set of micro motors 34; and elliptical plates 35 are fixedly installed at the upper end of each set of rotating rods 36. When the upper ends of the four sets of connecting rods 13 are brought into contact with the lower end of the corresponding assembly plate of the assembly equipment, the four sets of telescopic rods 33 are simultaneously activated, pushing the two sets of convex sliding plates 32. Moving upwards, the convex sliding plate 32 drives the elliptical plate 35 upwards via the micro motor 34 and the rotating rod 36, so that the elliptical plate 35 completely passes through the elliptical hole reserved in the assembly plate of the assembly equipment. Then, the micro motor 34 is controlled to rotate, and the micro motor 34 drives the elliptical plate 35 to rotate 90° via the rotating rod 36. After that, the four sets of telescopic rods 33 are controlled to move downwards. The four sets of telescopic rods 33 drive the two sets of elliptical plates 35 downwards via the convex sliding plate 32, the two sets of micro motors 34 and the two sets of rotating rods 36 until the two sets of elliptical plates 35 contact the upper end of the assembly plate of the assembly equipment, so that the mounting plate 1 can be assembled, improving the firmness of the mounting plate 1 and the assembly equipment.

[0043] The sliding arrangement of the two sets of convex sliding plates 32 and the four sets of connecting rods 13 allows the two sets of convex sliding plates 32 to slide up and down on the outer wall of the four sets of connecting rods 13 when the two sets of convex sliding plates 32 move up and down. This can guide the two sets of convex sliding plates 32 and improve the stability of the two sets of convex sliding plates 32 when they move up and down.

[0044] The usage method and working principle of this device are as follows: First, install the support base 11 and the round shaft base 14 onto the corresponding positions on the assembly plate of the assembly equipment, and then fix the mounting plate 1 to the lower end of the assembly plate through the mounting structure 3, and the upper ends of the four sets of connecting rods 13 are in contact with the lower end of the assembly plate.

[0045] Then, when the turntable 23 rotates to the feeding station, the feeding equipment conveys the rubber ring to the dropping seat 24. Two sets of No. 1 laser sensors 15 and two sets of No. 2 laser sensors 16 form a beam detection area. When the rubber ring material falls completely into the dropping seat 24, the laser beam is blocked. The sensor sends a high-level signal to the control module 12. After receiving the signal, the control module 12 drives the servo motor 21 to run. Through the transmission shaft 22, the turntable 23 rotates 90° clockwise, so that the dropping seat 24 containing the rubber ring material moves to the pushing station.

[0046] Finally, when the material dropper 24 reaches the push-in station, the control module 12 drives the push-in cylinder 27 to extend, pushing the two sets of push-in rods 28 to move upward. When the movable end of the push-in cylinder 27 approaches the upper contact sensor 17, the upper contact sensor 17 is triggered and sends a signal to the control module 12. The control module 12 immediately controls the push-in cylinder 27 to stop extending and switches to retraction. The push-in cylinder 27 drives the two sets of push-in rods 28 to move downward. When the movable end approaches the lower contact sensor 18, the lower contact sensor 18 is triggered and sends a signal. The control module 12 controls the push-in cylinder 27 to stop running, completing one push-in cycle.

[0047] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
