Description

Technical Field

[0001] This utility model relates to the field of O-ring feeding and processing technology, specifically to an automatic O-ring feeding machine. Background Technology

[0002] "O-rings" are rubber sealing rings with a circular cross-section. They are called O-rings because their cross-section is O-shaped. They first appeared in the mid-19th century and were used as sealing elements for steam engine cylinders. During the production and processing of O-rings, an automatic feeding machine is used to place the O-rings on the outer wall of the product for sealing.

[0003] However, existing automatic feeding machines only use a vibratory feeder to feed O-rings. This method is not very effective for feeding vents and for preparing O-rings, which reduces the efficiency of automated O-ring replenishment. Furthermore, the O-rings are directly fed to the feeding machine through hard friction, which does not significantly reduce the risk of O-ring wear.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings and proposed an automatic O-ring feeder. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic O-ring feeder to solve the problems mentioned in the background art, such as the low effect of vent-assisted feeding and the low effect of sealing ring preparation, which reduces the efficiency of automated sealing ring replenishment processing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic O-ring feeder, comprising a main body, an mounting plate installed on the outer wall of the main body, a vibratory feeder inlet on the outer wall of the mounting plate, an air blowing hole at the top of the vibratory feeder inlet, a first electric push rod on the outer wall of the main body, one end of the first electric push rod being fixedly connected to a push rod slidably connected to the outer wall of the mounting plate, a processing sleeve slidably connected to the outer wall of the main body, a feeding rod inserted into the inner wall of the processing sleeve, one end of the feeding rod abutting against a workpiece body, a second electric push rod on the outer wall of the main body, one end of the second electric push rod being fixedly connected to a sliding plate slidably connected to the outer wall of the main body, a third electric push rod on the outer wall of the sliding plate, a fourth electric push rod at the top of the sliding plate, a limit plate fixedly connected to one end of the fourth electric push rod, an O-ring body placed on the inner wall of the vibratory feeder inlet, and a through-groove on the inner wall of the mounting plate.

[0007] Furthermore, the outer wall of the mounting plate is provided with a through-beam infrared limit switch, and the through-beam infrared limit switch is located on one side of the through slot.

[0008] Furthermore, the outer walls of the first and second electric push rods are both equipped with reed sensors, and the outer walls of the third and fourth electric push rods located on one side of the second electric push rod are also equipped with reed sensors.

[0009] Furthermore, the outer wall of the mounting plate is provided with a peristaltic pump and an oiling rod connector, and the peristaltic pump and the oiling rod connector are arranged on the stroke trajectory of the O-ring body.

[0010] Furthermore, the outer wall of the mounting plate is provided with an operation viewing window, and the operation viewing window is set on each feeding path of the O-ring body.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model accelerates the feeding speed of the sealing ring by adding an air blowing hole and a through-beam infrared limit switch to detect the jig stroke, thereby confirming that the manual placement of the workpiece has reached a certain depth, thus realizing human-machine interaction. The action is only executed when there is a workpiece to be processed, so as to avoid the risk of empty running and avoid accidental touch that may cause empty running or even unpredictable safety risks.

[0013] 2. This utility model installs a magnetic reed sensor on each cylinder to check the cylinder position after power is applied, avoiding interference with the equipment mechanism. A peristaltic pump is added for stable and controllable oil supply to lubricate the contact surface between the fixture and the O-ring seal. Multiple operable and viewing windows are added to the outer frame for convenient maintenance. This replaces the manual feeding process and reduces the physical strain on personnel caused by long-term manual feeding. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1:

[0033] like Figures 1-15 As shown, an automatic O-ring feeding machine includes a main body 1, an mounting plate 2 installed on the outer wall of the main body 1, a vibratory feeder inlet 4 provided on the outer wall of the mounting plate 2, an air blowing hole 3 opened at the top of the vibratory feeder inlet 4, a first electric push rod 5 provided on the outer wall of the main body 1, one end of the first electric push rod 5 being fixedly connected to a push rod 6 slidably connected to the outer wall of the mounting plate 2, a processing sleeve 7 slidably connected to the outer wall of the main body 1, a feeding rod 8 inserted into the inner wall of the processing sleeve 7, and one end of the feeding rod 8... The device body 1 has a workpiece body 9 abutting against it. A second electric push rod 10 is provided on the outer wall of the device body 1. One end of the second electric push rod 10 is fixedly connected to a sliding plate 11 that is slidably connected to the outer wall of the device body 1. A third electric push rod 12 is provided on the outer wall of the sliding plate 11. A fourth electric push rod 13 is provided on the top of the sliding plate 11. A limit pressure plate 14 is fixedly connected to one end of the fourth electric push rod 13. An O-ring 15 is placed on the inner wall of the vibratory feed inlet 4. A through groove 16 is opened on the inner wall of the mounting plate 2.

[0034] like Figure 2 As shown, the outer wall of the mounting plate 2 is provided with a through-beam infrared limit switch, and the through-beam infrared limit switch is located on one side of the through slot 16. This allows the through-beam infrared limit switch on the outer wall of the mounting plate 2 to detect the travel of the fixture, thereby confirming that the manual placement of the workpiece has reached a certain depth, thus realizing human-machine interaction and ensuring that the action is only performed when there is a workpiece to be processed.

[0035] like Figure 4 As shown, the outer walls of the first electric push rod 5 and the second electric push rod 10 are both equipped with reed sensors. The outer walls of the third electric push rod 12 and the fourth electric push rod 13, which are located on one side of the second electric push rod 10, are also equipped with reed sensors. This allows for the use of reed sensors to check the position of the cylinder after power is applied, thus avoiding interference with the equipment mechanism.

[0036] like Figure 3 and Figure 4 As shown, the outer wall of the mounting plate 2 is equipped with a peristaltic pump and an oiling rod connector. The peristaltic pump and the oiling rod connector are positioned on the stroke trajectory of the O-ring body 15, which facilitates stable and controllable oil supply through the peristaltic pump and the oiling rod connector, and lubricates the contact surface between the fixture and the O-ring seal.

[0037] like Figure 5 and Figure 6 As shown, the outer wall of the mounting plate 2 is provided with an operation viewing window, and the operation viewing window is set on each feeding path of the O-ring body 15, which is convenient for maintenance.

[0038] Working principle: When using this type of automatic O-ring feeder, the sealing ring reaches the mounting plate 2 through the feeding device, and is smoothly dropped into the center hole of the mounting base assembly by gravity and air blowing, completing the material preparation. The worker manually pushes the workpiece body 9 against the feeding rod 8, and the device will open the cylindrical chuck. When the pull cylinder reaches the infrared detection point of the mounting plate 2, the clamping plate on the sliding plate 11 will extend and clamp the tail of the feeding rod 8. Then the sliding plate 11 will move backward, pulling the feeding rod 8 backward. When the front end of the feeding rod 8 leaves the material preparation port on the mounting plate 2, the feeding rod 8 will slide the O-ring body 15 into the workpiece, completing the installation. When the worker pulls out the feeding rod 8, the sliding plate 11 will move forward, pushing the feeding rod 8 forward. At this time, the next O-ring body 15 will fall into the through groove 16 on the mounting plate 2 and be inserted by the feeding rod 8, completing the feeding, waiting for the next workpiece to install the sealing ring.

[0039] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
