[0023] Example: Figures 1-5 As shown, an O-ring feeding mechanism includes a frame 100 and a feeding unit 200 and a discharging unit 300 mounted on the frame 100. The feeding unit 200 includes a feeding barrel 220 and a sealing plate 230. The feeding barrel 220 is movably mounted on the frame 100. The interior of the feeding barrel 220 is connected to an air blowing unit. The feeding barrel 220 is provided with a discharge port 224. The discharging unit 300 includes a flow channel bottom plate 320. The flow channel bottom plate 320 is provided with a flow channel 321. When the sealing plate 230 covers the feeding barrel 220, the discharge port 224 is connected to the flow channel 321. The air blowing unit can blow the O-rings in the feeding barrel 220 into the flow channel 321 through the discharge port 224. The feeding hopper 220 is used to store several O-rings. The air blowing unit is used to blow the multiple O-rings apart and blow individual O-rings onto the flow channel 321 to complete the O-ring feeding process. When feeding is required, the feeding hopper 220 is pulled out from under the sealing plate 230, and multiple O-rings are added into the feeding hopper 220. Then, the feeding hopper 220 is pushed under the sealing plate 230 so that the sealing plate 230 covers the feeding hopper 220. Then, the air blowing unit is activated. After the air blowing unit breaks apart the multiple sealing rings, the O-rings enter the flow channel 321 individually through the discharge port 224 to complete the O-ring feeding process.

[0024] The O-rings are stored in the feeding barrel 220, and the gas is used to scatter the plurality of O-rings, and the O-rings are separated and flow to the discharge port 224 and into the flow channel 321 along the airflow. The whole process can be automatically controlled, the feeding speed is fast, the accuracy is high, the stability is strong, and the feeding operation can be completed in 2 seconds at most. In the case of sufficient material, the machine can work continuously for 12 hours without stopping, thereby improving the production efficiency and reducing the production cost. The application can achieve the purpose of disordered feeding and ordered feeding. The O-ring feeding process is completed by blowing. As long as the number of O-rings meets the requirements, the feeding can be fast and stable. Multiple O-rings can be separated and fed at the same time, and the fragile O-rings will not be damaged. Under the condition of improving the feeding speed, the product scrap rate is reduced.

[0025] As shown in Figure 2 The upper end surface of the feeding barrel 220 is provided with a notch to form the discharge port 224. The feeding barrel 220 includes an inner cylinder 221 for storing the O-rings. The inner cylinder 221 is provided with a gas blowing hole 222. The gas blowing unit blows gas into the inner cylinder 221 through the gas blowing hole 222. The feeding barrel 220 is provided with a strip-shaped groove 225 at the notch position for gas scattering. When the feeding barrel 220 is located directly below the sealing plate 230, the sealing plate 230 covers the feeding barrel 220. The discharge port 224 is located on one side of the flow channel bottom plate 320, and the discharge port 224 is connected and communicated with the flow channel 321, so that the O-rings are driven by the airflow to enter the flow channel 321 through the discharge port 224.

[0026] As shown in Figure 2 The feeding barrel 220 further includes an outer cylinder 226. The outer cylinder 226 is arranged outside the inner cylinder 221, and a gap is arranged between the outer cylinder 226 and the inner cylinder 221. The outer cylinder 226 is fixedly provided with an air inlet pipe 223. The gas blowing hole 222 and the air inlet pipe 223 are both communicated with the gap. The air inlet pipe 223 is connected to the gas blowing unit. The gas blowing unit can be a blower, a gas booster, etc. The feeding barrel 220 includes the inner cylinder 221 and the outer cylinder 226 arranged outside the inner cylinder 221. A gap, i.e. the gap, is formed between the inner cylinder 221 and the outer cylinder 226. The gas blowing unit blows gas into the gap through the air inlet pipe 223. The airflow enters the inner cylinder 221 through the gas blowing hole 222 and scatters the O-rings in the inner cylinder.

[0027] As shown in Figure 1As shown in the figure, the rack 100 is fixedly provided with a base 110, and the base 110 is provided with a guide rail 111.

The sliding plate 210 is fixedly provided with an electrostatic silencer 250, and the sliding plate 210 can move horizontally along the guide rail 111. The pull plate 240 is pulled manually or by a cylinder to make the sliding plate 210 slide along the guide rail 111. Initially, the feeding barrel 220 is located below the sealing plate 230, that is, the sealing plate 230 covers the feeding barrel 220. When it is necessary to add material, the pull plate 240 is pulled out from below the sealing plate 230, so that the feeding barrel 220 moves to the O-ring feeding position, and then the O-ring is added to the feeding barrel 220. Finally, the pull plate 240 is pushed to make the feeding barrel 220 move to the position below the sealing plate 230 again, so that the sealing plate 230 covers the open end of the feeding barrel 220.

[0029] As shown in the figure, Figure 1 and Figure 5 The sealing plate 230 is installed on the rack 100 through guide columns 231, that is, the sealing plate 230 is installed on the base 110 of the rack 100 through the guide columns 231. The guide columns 231 are connected to a driving cylinder 232, and the driving cylinder 232 can drive the sealing plate 230 to move up and down. The sealing plate 230 is vertically installed on the base 110 through the guide columns 231, and the sealing plate 230 is driven to move up and down by the driving cylinder 232, so that the sealing plate 230 can be sealed and covered on the feeding barrel 220. That is, the position of the sealing plate 230 in the horizontal direction is fixed, and the position of the sealing plate 230 in the vertical direction is adjustable. When the feeding barrel 220 moves to the position directly below the sealing plate 230, the driving cylinder 232 drives the sealing plate 230 to descend to cover the sealing plate 230 on the feeding barrel 220.

[0030] As shown in the figure, Figure 1 and Figure 3As shown, the discharging unit 300 further comprises a support frame 310, a flow channel cover plate 330 and an O-ring pressing plate 340, the support frame 310 is fixedly installed on the rack 100, i.e. the support frame 310 is fixedly installed on the base 110 of the rack 100, the flow channel bottom plate 320 is fixedly installed on the support frame 310, the flow channel cover plate 330 is fixedly installed on the flow channel bottom plate 320, and the flow channel cover plate 330 covers the flow channel 321, and the O-ring pressing plate 340 is slidingly installed on the support frame 310. The flow channel cover plate 330 is fixedly installed above the flow channel bottom plate 320 and covers the flow channel 321, the flow channel 321 is a strip-shaped groove provided on the flow channel bottom plate 320, and the O-ring pressing plate 340 runs to the flow channel bottom plate 320 and blocks the outlet of the flow channel 321 between the flow channel bottom plate 320 and the flow channel cover plate 330 to prevent the O-ring from flying out.

[0031] The support frame 310 is fixedly provided with a sliding rail 311, the O-ring pressing plate 340 is slidingly installed on the sliding rail 311, the O-ring pressing plate 340 is connected to a pressing plate air cylinder, and the pressing plate air cylinder can drive the O-ring pressing plate 340 to run so that the O-ring pressing plate 340 presses the O-ring in the flow channel 321, and the flow channel bottom plate 320 is provided with an optical fiber sensor 322. The optical fiber sensor 322 is a pair of optical fibers, and the optical fiber sensor 322 is used to detect whether the O-ring is normally fed. Before feeding, the O-ring pressing plate 340 abuts against the flow channel bottom plate 320 under the action of the pressing plate air cylinder, when the O-ring is sent to the outlet of the flow channel 321 by the airflow, the O-ring pressing plate 340 blocks the O-ring, the optical fiber sensor 322 detects the O-ring, the air source stops supplying air, and the O-ring pressing plate 340 is retracted under the action of the pressing plate air cylinder to expose the O-ring for the external material taking unit to take the material.

[0032] The operation process of the present application comprises the following steps:

[0033] Step 1: pull the pull plate 240 out from below the sealing plate 230, make the feeding barrel 220 run to the O-ring feeding position, and then add the O-ring into the feeding barrel 220;

[0035] Step 3: the O-ring pressing plate 340 abuts against the flow channel bottom plate 320 under the action of the pressing plate air cylinder, then start the air blowing unit, the air blowing unit disperses the multiple sealing rings, and then makes the O-ring pass through the discharging port 224 into the flow channel 321, and the O-ring is blocked by the O-ring pressing plate 340;

[0036] Step 4: The optical fiber sensor 322 detects the O-ring, the air source stops supplying air, i.e. the air blowing unit is closed, and the O-ring pressing plate 340 is retracted under the action of the pressing plate cylinder, so that the O-ring is exposed for the external material taking unit to take materials.
