Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to an automatic feeding device. Background Technology

[0002] Vibratory feeders are core feeding equipment in industrial automated production, mainly used to achieve automatic sorting, orientation, and precise conveying of workpieces. They are widely used in manufacturing industries such as electronics, hardware, and pharmaceuticals.

[0003] Currently, vibratory feeders on the market generally consist of a circular vibration mechanism and a linear vibration mechanism. The circular mechanism uses inclined spring plates to drive a disc-shaped hopper in a torsional oscillation around its vertical axis. The material inside the hopper rises along a spiral track due to this vibration. During this ascent, after a series of track selections or posture changes, the material automatically enters the assembly or processing position in a uniform state according to assembly or processing requirements. Then, the linear vibration mechanism sequentially delivers the sorted material to the feeding position. However, if the material is large, the hopper needs to be enlarged; otherwise, the vibration requirements cannot be met, leading to an increase in the overall size of the vibratory feeder. Furthermore, adjusting the material movement speed of the circular vibration mechanism requires adjusting the vibration frequency, which is very cumbersome. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic feeding device with a simple and compact structure, suitable for various materials, and with a convenient and quick way to adjust the material transmission speed.

[0005] This utility model is achieved through the following technical solution:

[0006] An automatic feeding device, comprising:

[0007] A hopper having a discharge port and containing multiple material components;

[0008] The material pushing mechanism includes a driving component and at least one push plate assembly disposed at the discharge port. The push plate assembly includes a movable push plate and a fixed push plate disposed in parallel. The driving component is configured to drive the movable push plate to reciprocate along the discharge direction, thereby driving the material to move to the second end face of the fixed push plate.

[0009] A linear vibration mechanism is configured to contact the second end face of one of the fixed push plates and sequentially convey a plurality of the material components;

[0010] The material distribution mechanism is configured to interface with the linear vibration mechanism and convey the material to the blowing pipe.

[0011] Furthermore, the output shaft of the drive unit is fixedly connected to the movable push plate. When the output shaft is in the extended state, the top height of the movable push plate is lower than the top height of the fixed push plate. When the output shaft is in the retracted state, the top height of the movable push plate is higher than the top height of the fixed push plate.

[0012] Furthermore, there are two push plate groups arranged in a front-to-back direction. When the output shaft is in the extended state, the top height of the first fixed push plate is higher than the top height of the second movable push plate.

[0013] Furthermore, a first sensor is also provided inside the hopper. The first sensor is located at the bottom of the hopper and is configured to detect whether there are any materials.

[0014] The further described direct vibration mechanism includes a vibration drive and a conveying track, the conveying track being at least partially in contact with the second end face of the subsequent fixed push plate, and when the output shaft is in the retracted state, the top height of the subsequent movable push plate is higher than the conveying track, the vibration drive being configured to drive the conveying track to vibrate in order to move the material.

[0015] Furthermore, the material distribution mechanism includes a second driving member, a guide block, and a connecting block. The second driving member is configured to drive the connecting block to move along the X-axis direction. A paddle is fixed on the connecting block, and a slidable slider is provided on the connecting block. A guide groove is formed on the guide block, and the guide groove is inclined to the X-axis direction. The slider can move along the guide groove. When the slider moves, the paddle pushes the material on the slider away from the slider.

[0016] Furthermore, a second sliding groove is formed on the connecting block, the sliding groove is arranged perpendicular to the X-axis direction, the slider is at least partially disposed in the sliding groove, and the slider can move along the sliding groove.

[0017] Furthermore, the slider has a groove for receiving the material, and the material is at least partially located outside the groove and abuts against the lever.

[0018] Furthermore, the automatic feeding device also includes a belt conveyor line configured to convey materials into the hopper.

[0019] Furthermore, the automatic feeding device also includes a second sensor, which is disposed above the hopper and configured to detect the height of the multiple materials stacked in the hopper.

[0020] Compared with existing technologies, the advantages of this utility model are:

[0021] 1. By setting up a stepped movable push plate and a fixed push plate, the automatic stepped rolling conveying of materials under the action of the push plate and gravity is realized, which replaces the traditional vibratory feeder structure. The structure is simple and the feeding speed is easy to adjust.

[0022] 2. By dividing the electrical area and the mechanical area with a fixed base plate and setting up a partitioned chassis layout, the electrical components and mechanical parts are physically isolated, which improves equipment safety and facilitates maintenance.

[0023] 3. By setting a guide groove to drive the slider in conjunction with the material distribution mechanism of the pawl and the material drop hole, the material is accurately separated and can be conveyed into the blowing pipe in sequence. Attached Figure Description

[0042] The following detailed, non-limiting description of the utility model's technical solution, in conjunction with preferred embodiments and accompanying drawings, is provided. In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0043] like Figures 1 to 17 As shown in Embodiment 1 of this utility model, an automatic feeding device is provided for sequentially conveying multiple parts 9 into a blowing pipe. More specifically, in this embodiment, the parts 9 are rivets. The automatic feeding device includes a housing 7 and a hopper 1, a pushing mechanism 2, a vertical vibration mechanism 3, and a distributing mechanism 4 disposed within the housing 7. The hopper 1 is generally funnel-shaped, allowing the multiple parts 9 within the hopper 1 to accumulate at the bottom of the hopper 1 under gravity. The hopper 1 has a discharge port 10, and the pushing mechanism 2 is at least partially disposed within the discharge port 10, used to push the parts 9 from the hopper 1 to the vertical vibration mechanism 3. The vertical vibration mechanism 3 is used to arrange the multiple parts 9 neatly and sequentially convey them to the distributing mechanism 4, which then sequentially feeds the parts 9 into the blowing pipe. It is worth noting that the pushing mechanism 2 in this application is provided with a stepped pushing plate structure to convey the material 9 from the bottom of the hopper 1 to the vertical vibration mechanism 3 located at a higher position. Compared with the existing disc vibration type feeding equipment, the pushing plate structure of this application is simpler and the conveying speed of the material 9 is convenient and quick to adjust.

[0044] Specifically, refer to Figures 2 to 3 The housing 7 contains a fixed base plate 70, which divides the internal space of the housing 7 into an electrical area 71 and a mechanical area 72. The aforementioned hopper 1, pushing mechanism 2, linear vibration mechanism 3, and distributing mechanism 4 are all located in the mechanical area 72. The electrical area 71 contains commonly used electrical components such as solenoid valve assemblies, air sources, and controllers. Separating the electrical components from the mechanical parts greatly increases the safety of the equipment and makes maintenance easier. In addition, the housing 7 is also equipped with casters 74 for easy transportation.

[0045] Further reference Figures 3 to 7 The feeding mechanism 2 includes a first driving member 22 and at least one pusher plate group 21 disposed at the discharge port 10. The pusher plate group 21 includes a movable pusher plate 210 and a fixed pusher plate 211 disposed in parallel. The first driving member 22 is configured to drive the movable pusher plate 210 to reciprocate along the axial direction of the first driving member 22, thereby driving the material 9 to move to the second end face 211a of the fixed pusher plate 211, and finally conveying the material 9 located in the hopper 1 to the outside of the hopper 1.

[0046] Specifically, there are two pusher plate assemblies 21 arranged in a front-to-back direction. The pushing mechanism 2 includes a first fixed plate 23, one side of which is connected to the fixed base plate 70 by screws (not shown in the figure), and the other side is fixed with two second fixed plates 24. The pusher plate assemblies 21 and the first driving member 22 are both arranged between the two second fixed plates 24, and the fixed pusher plate 211 is fixed to the second fixed plates 24 on both sides by screws. The first driving member 22 is also fixedly connected to the second fixed plates 24, and the first driving member 22 is inclined. The output shaft 220 of the first driving member 22 is fixed to the movable pusher plate 210 located at the rear side through the first connecting plate 221. The movable pusher plate 210 located at the rear side is also fixed to the movable pusher plate 210 located at the front side through the second connecting plate 222, so that the first driving member 22 can simultaneously drive the two movable pushers 210 to move along the axial direction of the first driving member 22. When the output shaft 220 is in the extended state, the top height of each set of movable push plates 210 is lower than the top height of the fixed push plate 211. When the output shaft 220 is in the retracted state, the top height of the movable push plate 210 is higher than the top height of the fixed push plate 211. In addition, when the output shaft 220 is in the extended state, the top height of the previous fixed push plate 211 is higher than the top height of the next movable push plate 210.

[0047] To be more detailed, refer to Figure 5When the output shaft 220 is extended, the top height of the movable push plate 210 located at the front is lower than the minimum height of the discharge port 10. Therefore, the material 9 stacked at the bottom of the hopper 1 will roll down onto the first end face 210a of the movable push plate 210 located at the front under the action of gravity. When the output shaft 220 retracts, it will drive the movable push plate 210 to move relative to the corresponding fixed push plate 211, and convey the material 9 located on the first end face 210a to the second end face 211a of the fixed push plate 211 located in front. Since the top height of the previous fixed push plate 211 is higher than the top height of the next movable push plate 210 when the output shaft 220 is extended, the material 9 located on the second end face 211a of the fixed push plate 211 will fall onto the first end face 210a of the movable push plate 210 located behind. Similarly, when the output shaft 220 retracts, it drives the movable push plate 210 to move relative to the rearmost fixed push plate 211, and conveys the material 9 to the second end face 211a of the rearmost fixed push plate 211 to complete the discharge. It can be seen that as long as the first drive member 22 repeatedly extends and retracts, it can drive the material 9 in the hopper 1 to roll alternately along the arrangement direction of the push plate group 21 to the top of the movable push plate 210 and the fixed push plate 211, so as to achieve automatic discharge and improve the feeding efficiency.

[0048] Preferably, the first driving component 22 is a cylinder. If it is necessary to adjust the discharge speed of the material 9, only the air intake of the cylinder needs to be adjusted. Compared with the disc vibration type feeding equipment, the structure is simple and the way to adjust the discharge speed is more convenient and faster.

[0049] Furthermore, to ensure that the material 9 can roll alternately, both the movable push plate 210 and the fixed push plate 211 are inclined. At the same time, the movable push plate 210 and the fixed push plate 211 are fitted together in pairs to prevent the material 9 from getting stuck in the gap.

[0050] Optionally, the pushing mechanism 2 further includes a first limiting member 25, which is fixedly connected to the first fixed plate 23 and is arranged parallel to the movement direction of the push plate assembly 21. When the output shaft 220 is in the extended state, the first limiting member 25 abuts against the first connecting plate 22, thereby limiting the movable push plate 210 and preventing the first connecting plate 22 from contacting the first fixed plate 23, which could damage the equipment. Similarly, the pushing mechanism 2 also includes a second limiting member 26 and an abutting block 27. The second limiting member 26 is fixedly connected to the movable push plate 210 in front, and the abutting block 27 is located near the hopper 1 and fixedly connected to the second fixed plate 24. When the output shaft 220 is in the retracted state, the second limiting member 26 and the abutting block 27 abut against each other, limiting the movable push plate 210.

[0051] In addition, a first sensor 11 is provided at the bottom of the hopper 1 to detect whether there is a material 9 at the bottom of the hopper 1. Preferably, the first sensor 11 is a through-beam photoelectric sensor, with the emitting part and the receiving part of the through-beam photoelectric sensor respectively arranged on both sides of the hopper 1, and a detection port is opened at the corresponding position on the hopper 1 to allow the detection light used for detection to pass through.

[0052] Preferably, the automatic feeding device further includes a second sensor 6, which is disposed above the hopper 1 and configured to detect the height of multiple material parts 9 stacked in the hopper 1 to prevent the material parts 9 from overflowing the hopper 1.

[0053] Key reference Figure 8-10 The linear vibration mechanism 3 includes a vibration drive 30 and a conveying track 31. The conveying track 31 is at least partially connected to the second end face 211a of the subsequent fixed push plate 211. When the output shaft 220 is in the retracted state, the top height of the subsequent movable push plate 210 is higher than the conveying track 31, thereby allowing the material 9 to fall onto the conveying track 31. The vibration drive 30 is used to drive the conveying track 31 to vibrate, thereby moving the material 9.

[0054] Specifically, the direct vibration mechanism 3 includes a fixed base 32, which is fixedly connected to the fixed base plate 70. The fixed base 32 is used to raise the height of the conveying track 31 so that it can engage with the second end face 211a of the rear fixed push plate 211. A vibration connector 38 is fixedly disposed above the vibration drive component 30, and the vibration connector 38 is fixedly connected to the conveying track 31 to transmit the vibration of the vibration drive component 30 to the conveying track 31. Furthermore, the vibration drive component 30 is disposed on the fixed base 32, and a shock-absorbing component 33 is disposed between the vibration drive component 30 and the fixed base 32 to prevent the vibration of the vibration drive component 30 from affecting the fixed base plate 70. The specific structure of the shock-absorbing component 33 is prior art and will not be described in detail here. The vibration drive component 30 is also a commonly used vibration motor or electromagnetic exciter.

[0055] Furthermore, the conveying track 31 includes a first track 34 and a second track 35 connected in sequence. The first track 34 is connected to the next fixed push plate 211, and the material 9 can fall onto the first feeding platform 340 of the first track 34. The first feeding platform 340 has a protrusion 341 formed on the edge side near the fixed push plate 211, and the protrusion 341 is inclined from the inner edge of the first feeding platform 340. On the one hand, it does not prevent the material 9 from falling onto the first feeding platform 340, and on the other hand, it prevents the material 9 located on the first feeding platform 340 from falling onto the pusher mechanism 2 again. A baffle 342 inclined in the front-back direction is also provided on the side of the first feeding platform 340 away from the protrusion 341, so that the conveying surface 343 of the first feeding platform 340 for holding the material 9 gradually decreases in the front-back direction, thereby allowing multiple materials to be sorted in sequence when moving forward on the conveying surface 343.

[0056] The second track 35 includes a first stop 351 and a second stop 352, which are arranged in parallel and have a certain distance between them, thus defining a feeding groove 353 between the first stop 351 and the second stop 352. In this embodiment, the material 9 is a rivet. The diameter of the threaded portion of the rivet is smaller than the width of the feeding groove 353, while the diameter of the nut portion of the rivet is larger than the width of the feeding groove 353. Therefore, the rivet will be engaged in the feeding groove 353 with the threaded portion facing downwards and will be conveyed forward during the vibration of the second track 35.

[0057] Furthermore, to prevent the material 9 from falling outside the conveying track 31 during the process of falling from the first track 34 to the second track 35, chamfers 354 are formed on both the first stop 351 and the second stop 352 to provide a certain guiding effect for the material 9.

[0058] Optionally, a first upper baffle 36 is also provided above the feeding trough 353 to limit the vertical displacement distance of the material 9, so as to prevent the material 9 from falling out of the feeding trough 353 during vibration. The first upper baffle 36 is fixedly connected to the side of the aforementioned vibration connector 38 by an L-shaped fixing block 355, so that the first upper baffle 36 does not occupy the space of the feeding trough 353, and a third sensor 37 is also provided on the first upper baffle 36 to detect whether there is a material 9 at the third sensor 37.

[0059] Key reference Figures 11-14The material feeding mechanism 4 includes a second driving member 40, a guide block 42, and a connecting block 43. The second driving member 40 is used to drive the connecting block 43 to move along the X-axis direction. A paddle 44 is fixed on the connecting block 43, and a slidable slider 41 is provided on the connecting block 43. A guide groove 420 is formed on the guide block 42, which is inclined in the X-axis direction. The slider 41 can move along the guide groove 420. When the slider 41 moves, the paddle 44 pushes the material 9 on the slider 41 away from the slider 41, so that the material 9 falls into the blowing pipe, thereby completing the feeding.

[0060] Specifically, the material distribution mechanism 4 also includes a material distribution base 45 fixed to the fixed base 32. A first sliding groove 450 is formed on the material distribution base 45, and the first sliding groove 450 is arranged along the X-axis direction. A connecting block 43 is at least partially disposed within the first sliding groove 450 and moves along the first sliding groove 450. A second driving member 40 is also fixedly connected to the material distribution base 45, and the second output shaft of the second driving member 40 is fixedly connected to the connecting block 43, thereby enabling the second driving member 40 to drive the connecting block 43 to move along the X-axis direction.

[0061] A second sliding groove 430 is formed on the connecting block 43, and the second sliding groove 430 is arranged perpendicular to the X-axis direction. The slider 41 is at least partially disposed within the second sliding groove 430, and the slider 41 can move along the second sliding groove 430. At the same time, a guide rod 410 is fixed to one end of the slider 41, and the guide rod 410 is at least partially disposed within a guide groove 420 and can move along the guide groove 420. The other end of the slider 41 forms a material groove 410 for receiving the material 9, and the material 9 is at least partially located outside the material groove 410 and abuts against the lever 44.

[0062] In detail, refer to Figure 13 and Figure 14 When the second driving member 40 drives the connecting block 43 to move in the X-axis direction, the slider 41 moves along the guide groove 420 under the action of the guide rod 410, and at the same time, the slider 41 also moves in the second sliding groove 430. At this time, the slider 41 moves relative to the connecting block 43 in a direction perpendicular to the X-axis, which causes the material 9 on the slider 41 to tend to move in a direction perpendicular to the X-axis. At this time, the material 9 can only move in the X-axis direction under the abutment of the paddle 44, and finally causes the material 9 to detach from the material groove 410 and fall into the material drop hole 451 formed on the bottom wall of the first sliding groove 450, and then fall into the blowing pipe connected to the material drop hole 451.

[0063] refer to Figures 15-17 This application also provides a second embodiment of an automatic feeding device. Compared with the first embodiment, this embodiment adds a belt conveyor line 5 located above the hopper 1. The belt conveyor line 5 is used to transport the material 9 into the hopper 1 to reduce the number of manual feeding operations and thus improve efficiency.

[0064] Specifically, the automatic feeding device also includes a connecting column 50, which is used to raise the height of the belt conveyor 5 above the hopper 1 so that the material 9 can fall into the hopper 1 when discharged from the feed port 51 of the belt conveyor 5. One end of the connecting column 50 is fixedly connected to the fixed base 70 by screws, and the other end is fixedly connected to the belt conveyor 5. The belt conveyor 5 is a common belt conveying mechanism, and the belt conveyor 5 is equipped with a hopper 53 to store a certain number of material 9, avoiding the need for multiple additions of material 9 and thus improving efficiency.

[0065] Optionally, a fourth sensor 530 is also provided on the material bin 53. The fourth sensor 530 is located at the bottom of the material bin 53 and is used to detect whether there is a material 9 on the belt conveyor line 5. Preferably, the fourth sensor 530 is also a through-beam photoelectric sensor.

[0066] Optionally, the top of the chassis 7 is provided with a movable door 73 that can be opened and closed. When the operator needs to load materials, the movable door 73 can be opened to add materials 9 into the material bin 53.

[0067] In addition, a scanning detection device 8 is also installed on the chassis 7. The scanning detection device 8 is a common QR code or barcode scanning and recognition device. When the operator loads the material, he can align the barcode on the box of the material 9 with the scanning detection device 8 so that the scanning detection device 8 can obtain the information of the material 9 and help the operator determine whether the loading is correct.

[0068] This application achieves automatic stepped rolling conveying of material 9 under the action of multiple push plates and gravity by setting up a stepped movable push plate 210 and a fixed push plate 211, which replaces the traditional vibratory feeder structure. The structure is simple and the feeding speed is easy to adjust.

[0069] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
