[0023] Example: As Figures 1-5 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 communicates with a blowing unit. The feeding barrel 220 is provided with a discharging port 224. The discharging unit 300 includes a runner bottom plate 320, and a runner 321 is provided on the runner bottom plate 320. When the sealing plate 230 covers the feeding barrel 220, the discharging port 224 communicates with the runner 321. The blowing unit can blow the O-rings in the feeding barrel 220 into the runner 321 through the discharging port 224. The feeding barrel 220 is used to store a number of O-rings. The blowing unit is used to disperse a plurality of O-rings and blow a single O-ring onto the runner 321 to complete the feeding of the O-rings. When feeding is required, the feeding barrel 220 is pulled out from below the sealing plate 230, and a plurality of O-rings are added to the feeding barrel 220. Then the feeding barrel 220 is pushed back below the sealing plate 230 to make the sealing plate 230 cover the feeding barrel 220. Then the blowing unit is started. After the blowing unit disperses a plurality of sealing rings, the O-rings enter the runner 321 individually through the discharging port 224 to complete the feeding process of the O-rings.
[0024] In this application, the feeding bucket 220 is used to store O-rings, and gas is used to disperse multiple O-rings. After the O-rings are separated, they flow towards the discharge port 224 along with the air flow and enter the flow channel 321. The whole process can achieve automatic control, with a fast feeding speed, high precision, and strong stability. The feeding action can be completed in as fast as 2S. It can continuously work for 12 hours without stopping when there is sufficient material, thus improving production efficiency and reducing production costs. This application can achieve the purpose of disordered feeding and ordered loading. The O-ring feeding process is completed by the way of blowing air. During the feeding process, as long as the number of O-rings meets the requirements, fast and stable feeding can be carried out. 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 increasing the feeding speed, the scrap rate of products is reduced.
[0025] As Figure 2 shown, a notch is provided on the upper end surface of the feeding bucket 220 to form the discharge port 224. The feeding bucket 220 includes an inner cylinder 221 for storing the O-rings. The inner cylinder 221 is provided with air blowing holes 222, and the air blowing unit blows air into the inner cylinder 221 through the air blowing holes 222. The feeding bucket 220 is provided with a strip-shaped groove 225 at the notch position for air dispersion. When the feeding bucket 220 is directly below the sealing plate 230, the sealing plate 230 covers the feeding bucket 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 enter the flow channel 321 through the discharge port 224 under the drive of the air flow.
[0026] As Figure 2 shown, the feeding bucket 220 further includes an outer cylinder 226. The outer cylinder 226 is arranged outside the inner cylinder 221, and there is a sandwich between the outer cylinder 226 and the inner cylinder 221. An air inlet pipe 223 is fixedly arranged on the outer cylinder 226. Both the air blowing holes 222 and the air inlet pipe 223 communicate with the sandwich, and the air inlet pipe 223 is connected to the air blowing unit. The air blowing unit can be a blower, an air boosting pump, etc. The feeding bucket 220 includes an inner cylinder 221 and an outer cylinder 226 located outside the inner cylinder 221. A gap, that is, a sandwich, is formed between the inner cylinder 221 and the outer cylinder 226. The air blowing unit blows air into the sandwich through the air inlet pipe 223, and the air flow enters the inner cylinder 221 through the air blowing holes 222 and disperses the O-rings in the inner cylinder.
[0027] As Figure 1As shown, a base 110 is fixedly provided on the frame 100. A guide rail 111 is provided on the base 110. The feeding unit 200 further includes a sliding plate 210 and a pulling plate 240. The sliding plate 210 is slidably mounted on the guide rail 111. The feeding barrel 220 and the pulling plate 240 are fixedly mounted on the sliding plate 210. That is, the sliding plate 210 is slidably mounted on the base 110 through the guide rail 111. The presence of the pulling plate 240 can facilitate manual adjustment of the position of the feeding barrel 220.
[0028] As Figure 1 shown, the feeding barrel 220 is fixedly mounted on the sliding plate 210 through a support column 227. An electrostatic silencer 250 is fixedly provided on the sliding plate 210. The sliding plate 210 can move horizontally along the guide rail 111. The pulling 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 feeding is required, the pulling plate 240 is pulled out from below the sealing plate 230 to make the feeding barrel 220 run to the O-ring feeding position. Then, the O-ring is added into the feeding barrel 220. Finally, the pulling plate 240 is pushed again to make the feeding barrel 220 run below the sealing plate 230 again, so that the sealing plate 230 covers the open end of the feeding barrel 220.
[0029] As Figure 1 and Figure 5 shown, the sealing plate 230 is mounted on the frame 100 through guide posts 231, that is, the sealing plate 230 is mounted on the base 110 of the frame 100 through guide posts 231. The guide posts 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 mounted on the base 110 through the guide posts 231. The driving cylinder 232 drives the sealing plate 230 to move up and down, so that the sealing plate 230 can seal and cover the feeding barrel 220. That is, the position of the sealing plate 230 is fixed in the horizontal direction and adjustable in the vertical direction. When the feeding barrel 220 runs directly below the sealing plate 230, the driving cylinder 232 drives the sealing plate 230 to descend so that the sealing plate 230 covers the feeding barrel 220.
[0030] As Figure 1 and Figure 3As shown, the discharging unit 300 further includes a support frame 310, a runner cover plate 330, and an O-ring pressing plate 340. The support frame 310 is fixedly installed on the frame 100, that is, the support frame 310 is fixedly installed on the base 110 of the frame 100. The runner bottom plate 320 is fixedly installed on the support frame 310. The runner cover plate 330 is fixedly installed on the runner bottom plate 320, and the runner cover plate 330 covers the runner 321. The O-ring pressing plate 340 is slidably installed on the support frame 310. The runner cover plate 330 is fixedly installed above the runner bottom plate 320 and covers the runner 321. The runner 321 is a strip-shaped groove provided on the runner bottom plate 320. The O-ring pressing plate 340 runs to the runner bottom plate 320 and blocks the outlet of the runner 321 between the runner bottom plate 320 and the runner cover plate 330 to prevent the O-ring from flying out.
[0031] A slide rail 311 is fixedly provided on the support frame 310. The O-ring pressing plate 340 is slidably installed on the slide rail 311. The O-ring pressing plate 340 is connected to a pressing plate cylinder, and the pressing plate 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 runner 321. A fiber optic sensor 322 is provided on the runner bottom plate 320. The fiber optic sensor 322 is an opposed fiber optic. The fiber optic sensor 322 is used to detect whether the O-ring is properly loaded. Before loading, the O-ring pressing plate 340 abuts against the runner bottom plate 320 under the action of the pressing plate cylinder. When the O-ring is sent to the outlet of the runner 321 by air flow, the O-ring pressing plate 340 blocks the O-ring, and the fiber optic sensor 322 detects the O-ring, and the air source stops supplying air. The O-ring pressing plate 340 retracts under the action of the pressing plate cylinder, exposing the O-ring for the external material taking unit to take the material.
[0032] The operation process of this application includes the following steps:
[0033] Step 1: Pull out the pull plate 240 from below the sealing plate 230 to make the feeding barrel 220 run to the O-ring feeding position, and then add the O-ring into the feeding barrel 220.
[0034] Step 2: Push the pull plate 240 in the opposite direction to make the feeding barrel 220 run below the sealing plate 230 again. The driving cylinder 232 drives the sealing plate 230 to descend so that the sealing plate 230 covers the open end of the feeding barrel 220. At this time, the discharge port 224 is butted against the runner 321.
[0035] Step 3: The O-ring pressing plate 340 abuts against the runner bottom plate 320 under the action of the pressing plate cylinder, and then start the blowing unit. After the blowing unit scatters multiple sealing rings, the O-ring enters the runner 321 through the discharge port 224, and the O-ring pressing plate 340 blocks the O-ring.
[0036] Step 4: When the fiber optic sensor 322 detects the O-ring, the air supply stops to shut off the blowing unit, and the O-ring pressing plate 340 retracts under the action of the pressing plate cylinder, exposing the O-ring for the external material taking unit to take the material.
[0037] It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
