Description

Technical Field

[0001] This application relates to the technical field of feeding equipment, and particularly to a feeding device. Background Art

[0002] Some products usually have small parts. When installing the products, the small parts are generally sorted and fed manually, resulting in low feeding efficiency and high labor costs. Summary of the Utility Model

[0003] In view of this, this application provides a feeding device to realize the function of automatic feeding for small parts, so as to solve the problems of low feeding efficiency and high labor costs in manual feeding.

[0004] An embodiment of this application provides a feeding device, which includes a storage part, a covering component, a first blowing nozzle and a second blowing nozzle. The storage part has two opposite ends along the Z-axis direction. The storage part further includes a storage cavity, which is arranged on one side of the storage part along the Z-axis direction. The cross-section of the storage cavity perpendicular to the Z-axis direction is circular, and the storage cavity is used for storing materials. The covering component is detachably connected to one side of the storage part along the Z-axis direction. The covering component covers the storage cavity and forms a closed space for the storage cavity. The covering component includes a discharge port and a feeding pipeline. The discharge port is located on one side of the covering component along the direction perpendicular to the Z-axis. The feeding pipeline is connected to the covering component. The feeding pipeline includes a relatively connected feeding end and a discharging end. The feeding end of the feeding pipeline is communicated with the discharge port. The first blowing nozzle is arranged at one end of the storage part far from the discharge port. The first blowing nozzle is configured to blow air into the storage cavity periodically along the Z-axis direction, and make the materials in the storage cavity move close to the discharge port along the Z-axis direction. The number of the second blowing nozzles is at least two. All the second blowing nozzles are arranged on one side of the storage part along the direction perpendicular to the Z-axis. All the second blowing nozzles are distributed in sequence along the circumferential direction of the storage cavity. When the first blowing nozzle blows air into the storage cavity, all the second blowing nozzles blow air into the storage cavity in sequence along the circumferential direction of the storage cavity, and form a rotating air flow in the storage cavity. The discharge port is configured to discharge the air flow and materials in the storage cavity. The feeding pipeline is configured to lead the materials discharged from the discharge port to the outside. The Z-axis direction is arranged crosswise with the gravity direction.

[0005] In the above embodiment, the materials in the storage cavity are periodically blown up by the first blowing nozzle. At the same time, multiple second blowing nozzles blow air into the storage cavity and form a rotating air flow to drive the materials to rotate in the storage cavity. The air in the storage cavity then drives the materials to be discharged along the discharge port and the feeding pipeline, thereby realizing the function of automatic feeding.

[0006] In some embodiments, the feeding device further includes a feeding component, and the feeding component includes a cylinder and a receiving plate; the cylinder is located on one side of the feeding pipeline. The receiving plate is connected to the telescopic end of the cylinder. The cylinder is configured to drive the receiving plate to move along the extending direction of the feeding pipeline, and move the receiving plate from outside the discharging end to inside the discharging end, so that the receiving plate can receive the materials led out from the specified number of feeding pipelines. Or move the receiving plate carrying the materials from inside the discharging end to outside the discharging end.

[0007] In the above embodiments, the cylinder is used to push the receiving plate to receive materials, and the receiving plate conveys the specified number of materials from the feeding pipeline to outside the feeding pipeline, so as to realize the function of automatic quantitative feeding.

[0008] In some embodiments, the feeding component further includes a first detector. Along the moving direction of the receiving plate, the first detector is arranged on the side of the receiving plate away from the discharging end. The first detector is configured to send a feedback signal to the cylinder and the first blowing nozzle when the feeding pipeline leads the materials onto the receiving plate until the materials are within the detection range of the first detector, so that the cylinder drives the receiving plate to move away from the discharging end and the first blowing nozzle stops blowing. The first detector is further configured to send a feedback signal to the cylinder and the first blowing nozzle when the materials on the receiving plate are taken by the outside, so that the cylinder drives the receiving plate to move close to the discharging end and the first blowing nozzle blows air into the storage cavity.

[0009] In the above embodiments, the first detector is used to detect the materials on the receiving plate to control the operation of the cylinder and the first blowing nozzle.

[0010] In some embodiments, the feeding pipeline further includes a notch and a cover plate. The notch is located at the bottom of the discharging end, and the cover plate is connected to the top of the discharging end and extends outwards. The feeding component further includes two relatively spaced limiting plates. The two limiting plates are arranged on one side of the receiving plate along the Z-axis direction. The receiving plate and all the limiting plates enclose a first channel. A part of the receiving plate extends towards the discharging end along the moving direction of the receiving plate relative to the limiting plates. When the cylinder drives the receiving plate to move and drives the limiting plates to move close to the discharging end, a part of the receiving plate extends into the notch, and the cover plate extends between the two limiting plates and covers the first channel.

[0011] In the above embodiments, the cover plate is inserted between the limiting plates to make the first channel in a closed state to prevent the airflow from blowing the materials off, which helps to improve the stability of the materials on the receiving plate.

[0012] In some embodiments, the feeding pipeline further includes a first partition plate that extends along the extension direction of the feeding pipeline. The first partition plate divides the space inside the feeding pipeline into two second channels, and only one material can pass through each second channel at a time. The number of limiting plates on the receiving plate is three, and the three limiting plates are arranged at intervals. The receiving plate and all the limiting plates enclose two first channels, and one first channel corresponds to one second channel.

[0013] In the above embodiments, the feeding pipeline is divided into two second channels by the first partition plate, and two first channels are formed by three limiting plates. One second channel corresponds to one first channel, so as to realize the function of feeding outward from two first channels simultaneously.

[0014] In some embodiments, the feeding assembly further includes a second detector, which is arranged outside the cylinder. The second detector is used to detect the stroke of the cylinder and send a feedback signal to the cylinder.

[0015] In the above embodiments, the stroke of the cylinder is detected by the second detector to realize the function of controlling the moving position of the cylinder.

[0016] In some embodiments, the storage member includes a second partition plate, which is located inside the storage cavity. The second partition plate is recessed from the covering assembly towards the storage member and forms a hemispherical shape. The second partition plate includes a plurality of through holes, and all the through holes penetrate the second partition plate along the Z-axis direction. Both the first blowing nozzle and the second blowing nozzle are located on the side of the second partition plate away from the covering assembly along the Z-axis direction. The part of the storage cavity between the second partition plate and the covering assembly is used to store materials.

[0017] In the above embodiments, through the setting of the second partition plate, the air flows of the first blowing nozzle and the second blowing nozzle act on the materials in the storage cavity evenly.

[0018] In some embodiments, the covering assembly includes a main body and a top cover. The main body is located between the top cover and the storage member, and the main body is connected to the storage member. The main body includes a third channel, which penetrates the main body from the top cover towards the storage member. The third channel is communicated with the storage cavity, and the discharge port is located on the main body. When the first blowing nozzle and the second blowing nozzle blow air into the storage cavity, the materials in the storage cavity are discharged along the discharge port through the third channel. The top cover is used to cover the third channel.

[0019] In the above embodiments, the third channel is provided to facilitate adding materials into the storage cavity, and the third channel is covered by the top cover to maintain the sealing performance of the storage cavity.

[0020] In some embodiments, the main body further includes a first pressing plate and a second pressing plate, and the covering assembly further includes a first sealing ring, a second sealing ring, and a third sealing ring. The first pressing plate, the second pressing plate, the first sealing ring, the second sealing ring, and the third sealing ring are located between the top cover and the material storage member. In the direction from the top cover to the material storage member, the first sealing ring, the first pressing plate, the second sealing ring, the second pressing plate, and the third sealing ring are sequentially distributed. The top cover is detachably connected to the first pressing plate, and the second pressing plate is connected to the material storage member. Among them, both the first pressing plate and the second pressing plate are annular members, and the inner side walls of the first pressing plate and the second pressing plate together form the inner side wall of the third channel. The discharge port penetrates through the second pressing plate along a direction perpendicular to the Z-axis, and the feeding pipe is connected to the second pressing plate.

[0021] In the above embodiments, the discharge port is arranged on the second pressing plate, so as to facilitate replacing the second pressing plate with different discharge ports according to different materials. And through the sealing of the first sealing ring, the second sealing ring, and the third sealing ring respectively, the sealing performance of the covering assembly is maintained.

The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0070] Embodiments of the present application provide a feeding device, which includes a storage member, a covering assembly, a first blowing nozzle, and a second blowing nozzle. The storage member has two ends opposite to each other in the Z-axis direction. The storage member further includes a storage cavity, which is arranged on one side of the storage member in the Z-axis direction. The cross-section of the storage cavity perpendicular to the Z-axis direction is circular, and the storage cavity is used to store materials. The covering assembly is detachably connected to one side of the storage member in the Z-axis direction. The covering assembly covers the storage cavity and forms a closed space in the storage cavity. The covering assembly includes a discharge port and a feeding pipeline. The discharge port is located on one side of the covering assembly in the direction perpendicular to the Z-axis. The feeding pipeline is connected to the covering assembly. The feeding pipeline includes a relatively connected feeding end and a discharging end, and the feeding end of the feeding pipeline is communicated with the discharge port. The first blowing nozzle is arranged at one end of the storage member far from the discharge port, and the first blowing nozzle is configured to periodically blow air into the storage cavity in the Z-axis direction, and make the materials in the storage cavity move close to the discharge port in the Z-axis direction. The number of the second blowing nozzles is at least two, and all the second blowing nozzles are arranged on one side of the storage member in the direction perpendicular to the Z-axis. All the second blowing nozzles are sequentially distributed along the circumferential direction of the storage cavity. When the first blowing nozzle blows air into the storage cavity, all the second blowing nozzles sequentially blow air into the storage cavity along the circumferential direction of the storage cavity, and form a rotating air flow in the storage cavity. The discharge port is configured to discharge the air flow and materials in the storage cavity, and the feeding pipeline is configured to lead the materials discharged from the discharge port to the outside. The Z-axis is arranged to intersect with the gravity direction.

[0071] The materials in the storage cavity are periodically blown up by the first blowing nozzle. At the same time, multiple second blowing nozzles blow air into the storage cavity and form a rotating air flow to drive the materials to rotate in the storage cavity. The gas in the storage cavity then drives the materials to be discharged along the discharge port and the feeding pipeline, so as to realize the function of automatic feeding.

[0072] The following will describe some embodiments of the present application in conjunction with the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0073] In some embodiments, the positive direction of the Z-axis is vertically upward.

[0074] In some embodiments, please refer to Figures 1 to 3, A feeding device 10 includes a storage member 11, a covering assembly 12, a first blowing nozzle 13, and a second blowing nozzle 14. The storage member 11 is cylindrical and has a top end (not labeled) and a bottom end (not labeled) opposite to each other in the vertical direction. The storage member 11 further includes a storage cavity 111 which is arranged at the top end of the storage member 11 and is used for storing materials. The first blowing nozzle 13 is arranged at the bottom end of the storage member 11, is arranged upward, and is communicated with the storage cavity 111. The number of the second blowing nozzles 14 is three, and all the second blowing nozzles 14 are arranged on the side surface of the storage member 11. All the second blowing nozzles 14 are respectively communicated with the storage cavity 111, and all the second blowing nozzles 14 are sequentially distributed along the circumferential direction R of the storage cavity 111.

[0075] The covering assembly 12 is detachably connected to the storage member 11 and covers the storage cavity 111 to form a closed space for the storage cavity 111. The covering assembly 12 includes a discharge port 120 and a feeding pipeline 121. The discharge port 120 is located on one side of the covering assembly 12 in the horizontal direction. The feeding pipeline 121 includes a relatively connected feeding end 1211 and a discharging end 1212. The feeding end 1211 of the feeding pipeline 121 is connected to the covering assembly 12 and is communicated with the discharge port 120.

[0076] The feeding device 10 further includes a controller 17. During operation, the controller 17 controls the first blowing nozzle 13 to blow air upward into the storage cavity 111, so that the materials in the storage cavity 111 float up against gravity and move upward close to the discharge port 120, enabling the materials to be discharged along the discharge port 120 under the drive of the air flow, thereby realizing the automatic feeding function of the feeding device 10. The feeding pipeline 121 also conducts the materials discharged from the discharge port 120 to the outside, enabling external devices (such as a manipulator, etc.) to obtain the materials and reducing the risk of interference between the external devices and the storage member 11.

[0077] In addition, driving the materials to move by means of blowing air, as compared with driving the materials to move by means of vibration, helps to reduce noise and reduces the risk of damage to the materials due to collision.

[0078] In some embodiments, the shape of the discharge port 120 is substantially the same as the contour of the projection of the material in the specified direction, so that only the materials facing the specified direction can be discharged along the discharge port 120, thereby realizing the function of screening the materials. Exemplarily, when the material is a sealing ring and the feeding device 10 feeds the sealing ring, the axis of the sealing ring discharged along the discharge port 120 is parallel to the Z axis. At this time, please refer to Figure 3 and Figure 4 , the shape of the discharge port 120 is rectangular, and the length direction of the rectangle is parallel to the Y axis, so that only the sealing rings with axes parallel to the Z axis can be discharged along the discharge port 120.

[0079] Further, while the first air blowing nozzle 13 is blowing air, the controller 17 also controls all the second air blowing nozzles 14 to sequentially blow air into the storage cavity 111 along the circumferential direction R of the storage cavity 111, so as to form a rotating air flow in the storage cavity 111, and the rotating air flow drives the material to rotate around the axis of the storage member 11, so as to prevent the material not facing the specified direction from blocking the discharge port 120, which helps the material facing the specified direction to continuously discharge along the discharge port 120.

[0080] In other embodiments, when the controller 17 controls the first air blowing nozzle 13 to blow air, the controller 17 can also control all the second air blowing nozzles 14 to sequentially blow air into the storage cavity 111 along the opposite direction of the circumferential direction R of the storage cavity 111, so as to form a reverse rotating air flow in the storage cavity 111, and the reverse rotating air flow drives the material in the storage cavity 111 to rotate in the reverse direction.

[0081] In some embodiments, the cross-section of the storage cavity 111 in the horizontal direction is circular, which helps to reduce the obstruction to the rotational movement of the material by the inner side wall of the storage cavity 111.

[0082] In some embodiments, please refer to Figure 3 , all the second air blowing nozzles 14 are radially distributed with the storage cavity 111 as the center.

[0083] In other embodiments, the second air blowing nozzles 14 blow air into the storage cavity 111 along the tangential direction of the storage member 11. Thus, when all the second air blowing nozzles 14 blow air simultaneously, a rotating air flow can also be formed in the storage cavity 111, and compared with the single second air blowing nozzle 14 blowing air one by one, it helps to increase the flow rate of the rotating air flow and increase the pressure in the storage cavity 111.

[0084] In some embodiments, the number of the second air blowing nozzles 14 can be two, and the connecting line direction of the two second air blowing nozzles 14 does not pass through the axis of the storage cavity 111, so as to prevent the two second air blowing nozzles 14 from not being able to form a stable rotating air flow in the storage cavity 111 due to blowing air relatively.

[0085] In other embodiments, the number of the second air blowing nozzles 14 is more than three.

[0086] In some embodiments, please refer to Figure 2, the storage member 11 further includes a second partition 112 disposed in the storage cavity 111 to divide the storage cavity 111 into upper and lower parts (not labeled). The plate surface of the second partition 112 is provided with a plurality of through holes 113. The first blowing nozzle 13 and all the second blowing nozzles 14 are located on the side of the second partition 112 away from the covering assembly 12 in the Z-axis direction, and the material is located on the other side of the second partition 112 (i.e., the material is located in the upper part of the storage cavity 111). When the first blowing nozzle 13 and the second blowing nozzles 14 blow air into the storage cavity 111, the second partition 112 blocks the air flow, so that the air flow can evenly flow to the material through the plurality of through holes 113, which helps the air flow blown by the first blowing nozzle 13 and the second blowing nozzles 14 to act on the material evenly.

[0087] In some embodiments, please refer to Figure 2 , the second partition 112 is recessed downward to form a hemispherical shape, so that the plate surface of the second partition 112 is arranged in an arc shape, which facilitates the gas blown by the first blowing nozzle 13 or the second blowing nozzle 14 to flow along the arc surface, thereby reducing the blocking effect of the second partition 112 on the air flow.

[0088] Since some of the gas blown by the second blowing nozzle 14 is likely to concentrate in the lower part of the storage cavity 111 first, and then flow through the through holes 113 along the axial direction of the storage member 11 to the upper part of the storage cavity 111 and act on the material, the second blowing nozzle 14 generates a function similar to that of the first blowing nozzle 13. In some embodiments, in the Z-axis direction, the lowest point of the hemispherical second partition 112 is close to the first blowing nozzle 13, so that the air flow blown by the second blowing nozzle 14 can blow along the radial direction of the storage member 11 through the second partition 112 and flow towards the material, which helps the air flow blown by the second blowing nozzle 14 to drive the material to rotate.

[0089] In addition, through the arrangement of the second partition 112, the material in the storage cavity 111 can slide down along the side wall of the second partition 112 under the action of gravity and approach the first blowing nozzle 13, so that the first blowing nozzle 13 blows up all the materials.

[0090] In some embodiments, the control signal output by the controller 17 is a pulse signal, so that the controller 17 controls the first blowing nozzle 13 to work periodically. When the first blowing nozzle 13 stops blowing, all the materials in the storage cavity 111 fall under the action of gravity to adjust the angle of the materials or the relative positions between the materials. After the angle of the materials or the relative positions between the materials are adjusted, the controller 17 controls the first blowing nozzle 13 to blow again.

[0091] When the quantity of materials in the storage cavity 111 is small, the quantity of materials facing the specified direction is also small, resulting in a decrease in the probability that the materials can be discharged along the discharge port 120. When the quantity of materials in the storage cavity 111 is large, the movement range of the materials in the storage cavity 111 is limited, resulting in the inability to freely adjust the angle of the materials or the relative positions between the materials. In some embodiments, the volume of the materials stored in the storage cavity 111 is 1 / 3 to 2 / 3 of the total volume of the storage cavity 111, so as to increase the probability that the materials can be discharged along the discharge port 120 and enable the angle of the materials or the relative positions between the materials to be freely adjusted.

[0092] It can be understood that when the storage member 11 includes the second partition 112, the volume of the materials stored in the storage cavity 111 is 1 / 3 to 2 / 3 of the volume above the second partition 112 of the storage cavity 111, that is, the volume occupied by the materials is 1 / 3 to 2 / 3 of the space they are in.

[0093] In some embodiments, please refer to Figure 1 and Figure 2 , the feeding device 10 further includes a base 16, and the controller 17 and the storage member 11 are respectively arranged on the base 16, so that when feeding different devices respectively, the controller 17 and the storage member 11 can be synchronously driven to move by moving the base 16.

[0094] In some embodiments, please refer to Figure 3 , the storage member 11 includes a boss 114 provided at the edge of the top of the storage member 11. A support leg 115 is connected to the bottom of the boss 114, the support leg 115 is connected to the base 16, and the first air nozzle 13 passes through the base 16 and is connected to the bottom of the storage cavity 111.

[0095] In other embodiments, the storage member 11 is suspended above the base 16 through the support legs 115, and the first air nozzle 13 is arranged between the storage member 11 and the base 16.

[0096] In other embodiments, the boss 114 is a flange member detachably connected to the storage member 11.

[0097] In some embodiments, please refer to Figure 2 and Figure 3, the covering assembly 12 includes a main body 122 and a top cover 123. In the vertical direction, the main body 122 is located between the top cover 123 and the material storage member 11, and the main body 122 is connected to the top cover 123 and the material storage member 11 respectively. The main body 122 is provided with a third channel 1220. The third channel 1220 penetrates the main body 122 from the top cover 123 to the material storage member 11. The third channel 1220 communicates with the material storage cavity 111. The top cover 123 covers the third channel 1220 to isolate the third channel 1220 from the outside, so that the material storage cavity 111 forms a sealed state. When adding materials into the material storage cavity 111, the top cover 123 is opened so that the materials enter the material storage cavity 111 along the third channel 1220. The discharge port 120 is located on one side of the main body 122. When the first blowing nozzle 13 and the second blowing nozzle 14 blow air into the material storage cavity 111, the materials in the material storage cavity 111 are discharged along the discharge port 120 through the third channel 1220.

[0098] In some embodiments, please refer to Figure 3 , the main body 122 further includes a first pressing plate 1222 and a second pressing plate 1224. The covering assembly 12 further includes a first sealing member 1221, a second sealing member 1223 and a third sealing member 1225. The first pressing plate 1222, the second pressing plate 1224, the first sealing member 1221, the second sealing member 1223 and the third sealing member 1225 are located between the top cover 123 and the material storage member 11. Among them, both the first pressing plate 1222 and the second pressing plate 1224 are annular members. The inner side walls of the first pressing plate 1222 and the second pressing plate 1224 jointly form the inner side wall of the third channel 1220, that is, the third channel 1220 is located inside the first pressing plate 1222 and the second pressing plate 1224. In the direction from the top cover 123 to the material storage member 11, the first sealing member 1221, the first pressing plate 1222, the second sealing member 1223, the second pressing plate 1224, and the third sealing member 1225 are arranged in sequence. The top cover 123 is detachably connected to the first pressing plate 1222, and the second pressing plate 1224 is connected to the material storage member 11, so that the first sealing member 1221 seals between the top cover 123 and the first pressing plate 1222, the second sealing member 1223 seals between the first pressing plate 1222 and the second pressing plate 1224, and the third sealing member 1225 seals between the second pressing plate 1224 and the material storage member 11, thereby maintaining the sealing performance of the material storage cavity 111 and the third channel 1220.

[0099] Further, please refer to Figure 3 , the discharge port 120 penetrates the second pressing plate 1224 in a direction perpendicular to the Z-axis. The feeding pipe 121 is connected to the second pressing plate 1224. When the feeding device 10 feeds different materials, by replacing the second pressing plate 1224 with different discharge ports 120, the function of discharging different materials along the corresponding discharge ports 120 can be achieved.

[0100] In addition, the top cover 123 needs to be frequently opened. The first pressing plate 1222 is disposed between the top cover 123 and the second pressing plate 1224 to avoid the second pressing plate 1224 coming into direct contact with the top cover 123 and wearing during the disassembly and assembly process of the top cover 123, which helps to extend the service life of the second pressing plate 1224.

[0101] In some embodiments, when a boss 114 is provided at the top of the storage member 11, the second pressing plate 1224 is connected to the boss 114.

[0102] In some embodiments, both the second seal 1223 and the third seal 1225 are sealing gaskets. With the relatively large contact area of the sealing gaskets, the risk of air leakage generated by the first seal 1221 and the second seal 1223 can be reduced.

[0103] Furthermore, since the top cover 123 needs to be frequently disassembled, a sealing washer with a relatively large contact area and a relatively thin thickness is likely to generate friction and damage with the top cover 123. The first seal 1221 is an O-ring. When the top cover 123 is closed on the first pressing plate 1222, the top cover 123 acts on the first seal 1221 towards the first pressing plate 1222, so that the first pressing plate 1222 and the top cover 123 jointly clamp the first seal 1221, thereby realizing the function of the top cover 123 to seal the storage cavity 111. It can be understood that, compared with the sealing gasket, applying pressure to the O-ring with a relatively small contact area and good elasticity helps to reduce the friction between the top cover 123 and the first seal 1221 and helps to extend the service life of the first seal 1221.

[0104] In some embodiments, a limiting groove (not labeled) is provided at the top of the first pressing plate 1222, and the limiting groove is used to accommodate a part of the first seal 1221.

[0105] In other embodiments, all of the first seal 1221, the second seal 1223, and the third seal 1225 are O-rings, or all of the first seal 1221, the second seal 1223, and the third seal 1225 are sealing gaskets.

[0106] In some embodiments, please refer to Figure 1 and Figure 2, the discharge port 120 is located on one side of the covering assembly 12 in the X-axis direction, and the feeding pipe 121 extends in the X-axis direction. The feeding device 10 further includes a feeding assembly 15, and the feeding assembly 15 includes a cylinder 151 and a receiving plate 152; the cylinder 151 is connected to the base 16, and the cylinder 151, the feeding pipe 121, and the storage member 11 are arranged in sequence in the X-axis direction. The receiving plate 152 is connected to the telescopic end of the cylinder 151. When the material is discharged from the discharge port 120, the cylinder 151 drives the receiving plate 152 to move closer to the feeding pipe 121 in the X-axis direction, and makes the receiving plate 152 move from outside the discharge end 1212 to inside the discharge end 1212, so that the material is sequentially conveyed onto the receiving plate 152. When the receiving plate 152 bears a certain number of materials, the cylinder 151 drives the receiving plate 152 to move outward from inside the discharge end 1212 of the feeding pipe 121, so as to facilitate the external material transfer device to transfer the materials on the receiving plate 152 to the processing station, realizing the function of the feeding device 10 to supply a specified number of materials.

[0107] In some embodiments, please refer to Figure 2 , the feeding assembly 15 further includes a first detector 18, the first detector 18 is arranged on the side of the receiving plate 152 away from the feeding pipe 121, the first detector 18 is connected to the controller 17, when the material moves along the discharge end 1212 onto the receiving plate 152 and moves into the detection area of the first detector 18 along the extension direction of the feeding pipe 121, the first detector 18 sends a feedback signal to the controller 17, and the controller 17 controls the first air nozzle 13 to stop blowing air, so that the material in the storage cavity 111 stops discharging, and the controller 17 controls the cylinder 151 to drive the receiving plate 152 to move away from the feeding pipe 121, so that the external material transfer device can obtain the materials on the receiving plate 152. When the external material transfer device obtains the materials, there is no material in the detection area of the first detector 18, the first detector 18 sends a feedback signal to the controller 17, the controller 17 controls the cylinder 151 to drive the receiving plate 152 to move closer to the feeding pipe 121, and the controller 17 controls the first air nozzle 13 to blow air, so that the material in the storage cavity 111 continues to be discharged along the discharge port 120, improving the automation function of the feeding device 10.

[0108] In some embodiments, the first detector 18 is a position sensing element such as a photoelectric sensor or an ultrasonic sensor.

[0109] In some embodiments, the position of the first detector 18 or the range of the detection area of the first detector 18 can be adjusted to detect materials at different positions on the receiving plate 152. When the material moves to the preset position, the first detector 18 sends a feedback signal to the controller 17 to control the quantity of the materials received on the receiving plate 152, so as to realize the function that the feeding device 10 can accurately supply materials according to the requirements of different discharge quantities of the materials.

[0110] In some embodiments, referring to Figure 2 , Figure 3 and Figure 4 , the feeding pipe 121 further includes a notch 1213 and a cover plate 1214. The notch 1213 is located at the bottom of the discharging end 1212, and the cover plate 1214 is connected to the top of the discharging end 1212. The feeding assembly 15 further includes two relatively spaced limiting plates 153. The two limiting plates 153 are arranged on one side of the material receiving plate 152 along the Z-axis direction, and the two limiting plates 153 are located at one end of the material receiving plate 152 away from the discharging end 1212. The material receiving plate 152 and all the limiting plates 153 enclose a first channel 154. When the air cylinder 151 drives the material receiving plate 152 to move and makes the material receiving plate 152 drive the limiting plates 153 to move close to the discharging end 1212, a part of the material receiving plate 152 extends into the notch 1213, and the cover plate 1214 extends between the two limiting plates 153 and covers the first channel 154 until the side surface of the limiting plate 153 contacts the discharging end 1212 and the side surface of the material receiving plate 152 contacts the inner side wall of the notch 1213. Thus, in a mutually fitting manner, the first channel 154 forms a semi-closed state, and the movement of the material is restricted by the limiting plate 153 and the cover plate 1214 respectively, which helps to reduce the risk of the material on the material receiving plate 152 being blown off.

[0111] In some embodiments, referring to Figure 4 , the feeding pipe 121 further includes a first partition plate 1215. The first partition plate 1215 extends along the extending direction of the feeding pipe 121, and the first partition plate 1215 divides the space inside the feeding pipe 121 into two second channels 1216. The number of the limiting plates 153 on the material receiving plate 152 is three. The three limiting plates 153 are arranged at intervals along the Y-axis direction. The material receiving plate 152 and all the limiting plates 153 enclose two first channels 154. Each first channel 154 is located between two adjacent limiting plates 153, and one first channel 154 corresponds to one second channel 1216. Among them, only one material can pass through each second channel 1216 each time. One first channel 154 accommodates a group of materials. Through the arrangement of the two first channels 154 and the two second channels 1216, the material receiving plate 152 can carry two groups of materials simultaneously, which helps to increase the feeding quantity of the feeding assembly 15.

[0112] In other embodiments, the number of the limiting plates 153 is more than three, the number of the first partition plates 1215 is two or more, and the number of the first partition plates 1215 is two less than the number of the limiting plates 153, so as to set a plurality of first channels 154 and a plurality of second channels 1216, thereby realizing the function of the material receiving plate 152 carrying multiple groups of materials simultaneously.

[0113] It can be understood that the width of the discharge port 120 increases or decreases corresponding to the number of the second channels 1216.

[0114] In some embodiments, a part of the feeding pipe 121 is integrally provided with the second pressing plate 1224, and the cover plate 1214 is detachably connected to the second pressing plate 1224.

[0115] In other embodiments, the whole of the feeding pipe 121 is integrally provided with the second pressing plate 1224.

[0116] In some embodiments, please refer to Figure 4 , the feeding assembly 15 further includes a slider 1511. The slider 1511 is connected to the telescopic end of the air cylinder 151. The slider 1511 has a side surface (not marked) facing the receiving plate 152. One side of the receiving plate 152 away from the feeding pipe 121 is connected to the side surface of the slider 1511. When the material is conveyed to the receiving plate 152, the side surface of the slider 1511 can contact the material and limit the movement of the material, so as to realize the function of limiting the material.

[0117] When the cover plate 1214 moves between the two limiting plates 153, there is a gap (not marked) between the cover plate 1214 and the slider 1511, so that the gas blown out by the first blowing nozzle 13 and the second blowing nozzle 14 can finally be discharged along the gap between the cover plate 1214 and the slider 1511.

[0118] In some embodiments, please refer to Figure 4 , the first detector 18 is disposed through the slider 1511.

[0119] In some embodiments, please refer to Figure 1 and Figure 4 , the feeding assembly 15 further includes a second detector 19. The second detector 19 is disposed outside the air cylinder 151 to detect the stroke of the air cylinder 151. When the piston of the air cylinder 151 moves into the detection range of the second detector 19, the second detector 19 sends a feedback signal to the controller 17, so that the controller 17 controls the air cylinder 151 to stop working, and improves the accuracy of driving the receiving plate 152 to move to a specified position by the air cylinder 151.

[0120] In some embodiments, the second detector 19 is a magnetic inductor, and a magnetic ring is provided on the piston of the air cylinder 151.

[0121] In other embodiments, the second detector 19 is a photoelectric switch, and a baffle is provided at the telescopic end of the air cylinder 151.

[0122] In some embodiments, the cylinder 151, the feeding pipe 121, and the discharging port 120 are located on one side of the storage member 11 in the positive direction of the X-axis, and all the second blowing nozzles 14 are located on one side of the storage member 11 in the negative direction of the X-axis, so as to reduce the risk of interference between the feeding pipe 121 or the cylinder 151 and the second blowing nozzles 14.

[0123] In other embodiments, the feeding pipe 121 is arranged in a zigzag shape, the cylinder 151 is located on one side of the discharging end 1212 of the feeding pipe 121, and the cylinder 151 drives the receiving plate 152 to approach or move away from the discharging end 1212 along the extension path of the discharging end 1212 of the feeding pipe 121.

[0124] In some embodiments, the number of the discharging ports 120 is two or more, the number of the feeding pipes 121 and the feeding assemblies 15 is the same as that of the discharging ports 120, and one feeding pipe 121, one feeding assembly 15, and one discharging port 120 correspond to each other one by one, so as to realize the function of the feeding device 10 feeding in multiple directions simultaneously.

[0125] In other embodiments, the covering assembly 12 and the main body 122 are integrally provided.

[0126] In other embodiments, the horizontal height of the discharging end 1212 of the feeding pipe 121 is lower than that of the feeding end 1211, and the material can also move from the feeding end 1211 to the discharging end 1212 under the action of gravity.

[0127] In other embodiments, the Z-axis direction and the gravity direction are arranged in a cross manner.

[0128] In addition, those of ordinary skill in the art in this technical field should recognize that the above embodiments are only used to illustrate the present application, rather than to limit the present application. As long as it is within the substantial scope of the present application, appropriate changes and variations made to the above embodiments fall within the scope disclosed in the present application.
