Background

Some medical devices require the use of O-rings to perform the sealing function. However, in the automatic production process of the medical device, the O-ring is in a stacked state. If the mechanical arm is adopted to directly clamp the O-shaped rings, a plurality of O-shaped rings are easily clamped simultaneously, and therefore automatic assembly of a single O-shaped ring cannot be achieved. The prior art generally adopts the mode of vibration dish feed to part accumulational O type circle. However, in the case of conveying the O-ring separated from the vibration plate, it is common in the related art to convey the O-ring by vibration generated by a vibration motor. Therefore, in the conveying process, part of the O-shaped rings are soft due to large diameters and are easy to deform, so that the conveying efficiency is low. Similar problems exist with materials other than O-rings, similar to O-rings. Therefore, how to improve the single feeding efficiency of materials similar to the O-ring is a problem to be solved urgently.

As used in the description of the present application, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, an embodiment of the present application discloses a feeding device, which includes a discharging assembly 100, a first material taking assembly 200, a transferring assembly 300, a second material taking assembly 400, and a detecting assembly 500.

Referring to fig. 2, the discharging assembly 100 includes a vibrating plate 110, a first limiting plate 120, a second limiting plate 130, a limiting plate positioning member 140, a first limiting member 150, a second limiting member 160, and a limiting driving member 170. The first limiting plate 120, the second limiting plate 130 and the limiting plate positioning member 140 are located outside the vibratory pan 110. The first limiting plate 120 and the second limiting plate 130 surround to form an accommodating channel. The receiving passage is communicated with the inside of the vibration plate 110 so that the materials in the vibration plate 110 are separated by the vibration plate 110 and then sequentially enter the receiving passage one by one. The first and second limiting

plates

120 and 130 are relatively movable to adjust the width of the accommodating passageway perpendicular to the moving direction of the material along the accommodating passageway. The position-limiting-plate positioning member 140 fixes the position of the first and second position-limiting

plates

120 and 130 after the relative movement. Specifically, the first limiting plate 120 and the second limiting plate 130 are respectively provided with a plurality of positioning holes, and when the same positioning hole of the first limiting plate 120 is aligned with a different positioning hole of the second limiting plate 130, the width of the accommodating channel perpendicular to the material along the moving direction of the accommodating channel is changed. The position-limiting plate positioning member 140 is inserted into the aligned positioning hole of the first position-limiting plate 120 and the aligned positioning hole of the second position-limiting plate 130, so that the positions of the first position-limiting plate 120 and the second position-limiting plate 130 after relative movement are fixed, and the width of the accommodating passage perpendicular to the movement direction of the material along the accommodating passage is also fixed. The width of the receiving channel is adapted to the outer diameter of the material, so that the material is distributed as far as possible in the direction of movement, and the mutual influence of the material during movement in the receiving channel is reduced. The containing channel guides two adjacent materials in the containing channel to be arranged along the radial direction, and meanwhile, the extending direction of the containing channel is perpendicular to the horizontal plane, so that the materials can move along the containing channel under the action of self gravity. The first limiting member 150 is connected to one end of the first limiting plate 120 away from the vibrating plate 110 or one end of the second limiting plate 130 away from the vibrating plate 110, so that the first limiting member 150 is located at one end of the accommodating channel away from the vibrating plate 110 and located in a moving direction of the material along the accommodating channel. When the material moves along the accommodating channel to abut against the first limiting member 150, the first limiting member 150 limits the movement of the material to position the material. And a discharge hole 180 is formed between one end of the first limiting plate 120 or the second limiting plate 130 close to the first limiting member 150 and the first limiting member 150. The discharge opening 180 is offset from the material in the direction of movement of the receiving channel. The material can exit the receiving channel through the discharge port 180. The maximum width of the discharge port 180 is smaller than the outer diameter of the material, so that the material cannot spontaneously pass through the discharge port 180. And when the material is deformed when passing through the discharge port 180, the material can pass through the discharge port 180 to leave the accommodating channel. The second retaining member 160 is located outside the receiving channel to limit the material from exiting the receiving channel from the outlet 180. The second stopper 160 is provided with an escape passage 161. The limit driving member 170 drives the second limiting member 160 to move to no longer limit the material from leaving the accommodating channel from the discharge hole 180. Meanwhile, the material taking channel 190 is provided on the first limiting plate 120 or the second limiting plate 130. The take-out passage 190 communicates not only with the inside of the accommodating passage and the outside of the accommodating passage, but also with the discharge port 180. The material can be positioned by moving along the accommodating channel under the action of the gravity of the material when abutting against the first limiting member 150 in the moving process of the material along the accommodating channel. The positioned material is obtained by the first limiting member 150, and the material is conveyed. Therefore, the vibration generated by the vibration motor in the prior art is not needed to be adopted for conveying, and the materials move under the action of self gravity when moving along the accommodating channel, so that the deformation is not easy to occur, and the conveying efficiency is higher. Therefore, the feeding device can improve the material feeding efficiency.

Referring to fig. 2, the first take assembly 200 includes a first take member 210 and a second take member 220. The first material taking part 210 and the second material taking part 220 clamp the part of the material exposed out of the accommodating channel through the material outlet 180. During the process of clamping the material by the first material taking member 210 and the second material taking member 220, the material taking channel 190 and the avoiding channel 161 function as avoiding, and the second limiting member 160 is still at the position for limiting the material to leave the accommodating channel from the material outlet 180. After the first material fetching member 210 and the second material fetching member 220 clamp the material, the second limiting member 160 is driven by the second limiting member 160 to no longer limit the material from leaving the accommodating channel from the material outlet 180. The material takes place elastic deformation when first getting material 210 and the drive of second getting material 220 down through discharge gate 180 to the material resumes elastic deformation after leaving the accommodation channel.

Referring to fig. 3, the relay assembly 300 includes a relay member 310 and a support member 320. The transit 310 and the support 320 are connected so that the transit 310 is positioned by the support 320. The transit member 310 is provided with a transit passage 311, a first passage 312, and a second passage 313. The first passage 312 and the second passage 313 are both communicated with the transfer passage 311. The first picking member 210 and the second picking member 220 clamp the material and enter the transfer passage 311 through the first passage 312, and then the first picking member 210 and the second picking member 220 no longer clamp the material and leave the transfer passage 311 through the first passage 312. When the first material taking part 210 and the second material taking part 220 clamp the material and enter the transfer passage 311 through the first passage 312, the material is elastically deformed to enter the transfer passage 311 and then is elastically deformed after entering the transfer passage 311. If the transfer member 310 is not provided, when the third material taking member 410 and the fourth material taking member 420 are inserted into the material and start to move in opposite directions, the material is further deformed by the third material taking member 410 and the fourth material taking member 420, so that the first material taking member 210 and the second material taking member 220 are influenced by the material to be increased. In other words, the opposite movement of the third material taking part 410 and the fourth material taking part 420 is affected by the material more, so that the difficulty of the opposite movement of the third material taking part 410 and the fourth material taking part 420 is increased. In the case of the transfer member 310, the first and second

material taking members

210 and 220 may clamp the material into the transfer passage 311 through the first passage 312, and then may release the material. The third picking member 410 and the fourth picking member 420 then clamp the material and enter the transfer passage 311 through the second passage 313 to clamp the material. At this time, the material is not limited, so that the opposite movement of the third material taking part 410 and the fourth material taking part 420 is relatively less affected by the material, and the difficulty of the opposite movement of the third material taking part 410 and the fourth material taking part 420 is relatively less.

Referring to fig. 3 and 4, the second take off assembly 400 includes a third take off member 410 and a fourth take off member 420. The third take-off member 410 and the fourth take-off member 420 enter the transit passage 311 through the second passage 313. The third taking member 410 and the fourth taking member 420 are inserted into the material after entering the interior of the transfer passage 311. The third and fourth picking

members

410 and 420 move in opposite directions so that the third and fourth picking

members

410 and 420 grip the material. The material is elastically deformed by the third material taking part 410 and the fourth material taking part 420. At this time, the third and fourth take off

members

410 and 420 exit the relay passage 311 from the second passage 313, and the material exits the relay passage 311 with the third and fourth take off

members

410 and 420. The material remains elastically deformed after leaving the transit passage 311.

Referring to fig. 2, the sensing assembly 500 includes a sensing member 510 and a sensing positioning member 520. The detecting member 510 is used for detecting whether the amount of the material in the accommodating channel meets the set value. The detecting and positioning member 520 fixes the position of the detecting member 510 after moving relative to the discharging assembly 100. The material moves along the containing channel under the action of the gravity of the material. Therefore, if the material in the accommodating channel is too much, the material at the bottom is more extruded, and the deformation is larger. While the material at the bottom is first picked up by the first take off assembly 200. Therefore, if the amount of material in the receiving channel is not certain, the degree of deformation of the material at the bottom is not certain, and the material at the bottom cannot be always obtained by the first material taking assembly 200. The amount of material in the containment channel is controlled to be constant by the detection of detector 510 so that the degree of deformation of the material at the bottom is determined so that the material at the bottom can always be accessed by first take out assembly 200.

It can be understood that the material can be an O-ring or other parts required by the medical apparatus which can be loaded by the loading device of the present application.

It will be understood that the extension direction of the receiving channel may also be arranged obliquely with respect to the horizontal plane or the extension direction of the receiving channel may also vary, as long as the material can move along the receiving channel under the effect of its own weight.

It is understood that the discharge hole 180 may also be disposed on the first limiting member 150.

It is understood that the first and second taking

members

210 and 220 may be inserted into the material through the taking channel 190 from the outside of the receiving channel into the inside of the receiving channel, and the first and second taking

members

210 and 220 are inserted into the material after entering the inside of the receiving channel. The first and second picking

members

210 and 220 move in opposite directions so that the first and second picking

members

210 and 220 grip the material. At this time, the material is elastically deformed by the first material taking member 210 and the second material taking member 220. Subsequently, the first material taking member 210 and the second material taking member 220 move from the material taking channel 190 to pass through the material outlet 180 to leave the accommodating channel, and the material passes through the material outlet 180 along with the first material taking member 210 and the second material taking member 220 to leave the accommodating channel. The material remains elastically deformed after leaving the containing channel. Subsequently, when the first material taking part 210 and the second material taking part 220 clamp the material to enter the transfer passage 311 through the first passage 312, the material does not need to be elastically deformed. Subsequently, the first and second picking

members

210 and 220 are moved towards each other so that the first and second picking

members

210 and 220 no longer grip the material. And the material starts to restore the elastic deformation when the first picking member 210 and the second picking member 220 move towards each other. Of course, the reclaiming path 190 may not be provided, but rather may be provided to transfer the parts. After the material is got in the middle of the commentaries on classics and is taken out the material from holding the passageway through discharge gate 180, first get material 210 and second get material 220 and reinsert inside the material, finally realize first material subassembly 200 centre gripping material of getting.
