Description

Technical Field

[0001] This invention relates to the field of automated production technology, and in particular to a feeding device. Background Technology

[0002] In the wave of intelligent manufacturing, automated feeding equipment, as the core link of material flow in the production line, directly determines the production efficiency and product yield of downstream enterprises through its stability, precision and integration level. It is widely used in the automation equipment matching of 3C electronics, automotive parts and other fields, among which the precision feeding requirements of AOI (automatic optical inspection) equipment are particularly typical.

[0003] However, current feeding devices have the following drawbacks. Taking vibratory feeders as an example, their feeding flexibility is insufficient, and they are only suitable for parts of a single shape or size. They have poor compatibility with irregularly shaped and fragile materials such as small precision electronic components required for AOI inspection. Furthermore, when changing the feeding material, the machine must be stopped and the track must be readjusted, resulting in low changeover efficiency. In addition, there is a problem of low integration. Feeding and screening are mostly separate processes, which means that materials must go through multiple stages such as feeding, transfer, and screening before entering the subsequent inspection process. This not only prolongs the material flow cycle but also increases the risk of secondary damage to the materials. Summary of the Invention

[0004] The purpose of this invention is to provide a feeding device that addresses the problems of insufficient feeding flexibility and low integration in existing feeding devices.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: This application provides a feeding device, comprising: A roller feeding assembly having a receiving cavity for accommodating materials, the receiving cavity having a first opening and a second opening for communicating with the outside through the first opening and the second opening; A screening and conveying assembly having a feeding end and a discharging end disposed opposite to the feeding end, the feeding end extending into the receiving cavity through the first opening; A material separation assembly includes a separation mechanism and a screening mechanism disposed on a screening and conveying assembly. The separation mechanism and the screening mechanism are arranged side by side along a first direction. The separation mechanism includes a support body and a first horizontal separation member disposed on the screening and conveying assembly. The support body extends along the first direction. The first horizontal separation member has a first end and a second end disposed opposite to the first end. The first end of the first horizontal separation member abuts against the support body, and the second end of the first horizontal separation member is movably connected to the support body and can move closer to or further away from the support body along a second direction. The screening mechanism extends along the first direction and can move relative to the screening and conveying assembly in the second direction to be flush with the second end. The first direction is the conveying direction of the screening and conveying assembly, and the second direction is the width direction of the screening and conveying assembly. The first direction and the second direction are perpendicular.

[0006] The beneficial effects of the present invention are as follows: The feeding device of the present invention operates as follows: the material is concentrated in the receiving cavity of the roller feeding assembly, and the material is continuously fed onto the feeding end of the screening and conveying assembly from the first opening. The second opening (discharge port) is equipped with a sensor to detect the material level, and the screening and conveying assembly is started and stopped according to the material flow to achieve uninterrupted feeding. Thus, each material is conveyed to the screening and separating assembly along with the screening and conveying assembly. Specifically, the material is first separated by the separating mechanism, so that each material is sequentially sorted under the drive of the screening and conveying assembly and the action of the first horizontal separator, and then orderly enters the screening mechanism for screening. The second end of the first horizontal separator can move relative to the supporting body, and the screening mechanism can also adapt to the adjustment of the relative position of the second end of the first horizontal separator. This allows for adjustment of the flow width of the separated and screened material, improving adaptability to materials of different sizes and increasing the flexibility of material screening. Furthermore, the separation and screening actions are integrated into the screening and separating assembly, which can be completed with a single component, resulting in a higher degree of integration.

[0007] In some embodiments, the support body has a first side surface, and the first horizontal separator has a second side surface that smoothly transitions to the first side surface, the second side surface being used to guide the material; or... The second side is a curved side.

[0008] In some embodiments, the first horizontal separating member includes a horizontal fixing portion connected to the support body, a horizontal sliding portion slidably connected to the horizontal fixing portion, and a horizontal separating portion connected to the horizontal sliding portion, the horizontal separating portion having a first end, a second end, and the arcuate side surface.

[0009] In some embodiments, the screening and separating assembly further includes a second horizontal separating member disposed on the first side of the support body and located at the first opening. The second horizontal separating member has a third side for guiding the material, which passes sequentially through the third side and the second side along the first direction.

[0010] In some embodiments, the screening and separating assembly further includes a vertical separating member, which includes a vertical fixing part disposed on the support body, a vertical sliding part slidably connected to the vertical fixing part, and a vertical separating part connected to the vertical sliding part. The vertical separating part moves up and down relative to the screening and conveying assembly along a third direction, which is a direction perpendicular to the plane where the screening and conveying assembly is located. The vertical separation section is arranged at an angle to the first direction, and the vertical distribution section is placed horizontally on the screening and conveying assembly to cut off the material on the screening and conveying assembly.

[0011] In some embodiments, the upper feeding device further includes a return conveying component that is opposite to the conveying direction of the screening and conveying component. The return conveying component is arranged side by side with the screening and conveying component along the second direction, and the return conveying component extends into the receiving cavity through the first opening to recover the material blocked by the vertical separation section.

[0012] In some embodiments, the screening mechanism includes a screening main body, a visual detection unit disposed on the screening main body, and an air blowing unit communicating with the screening main body. The screening main body extends along the first direction and is movable relative to the screening transmission component in the second direction to be flush with the second end. The screening main body has an air blowing hole communicating with the air blowing unit. The visual detection unit and the air blowing hole are arranged sequentially along the first direction. The return transmission component extends along the first direction to the air blowing hole.

[0013] In some embodiments, the screening main body includes a screening main frame extending along the first direction and an adjustment main frame connected to the screening main frame. The screening main frame is provided with the visual detection unit and the air blowing hole. The adjustment main frame is used to adjust the position of the screening main frame relative to the screening transmission component in the second direction.

[0014] In some embodiments, the adjusting main frame includes a vertical rod erected on one side of the screening and conveying assembly and a horizontal rod movably connected to the vertical rod, with one end of the horizontal rod away from the vertical rod connected to the screening main frame.

[0015] In some embodiments, the screening mechanism further includes a guide plate slidably connected to one side of the screening transmission assembly and corresponding to the visual inspection unit. Attached Figure Description

Detailed Implementation

[0019] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] In the description of this invention, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] In the field of feeding technology, the following defects are commonly found. Taking vibratory feeders as an example, their feeding flexibility is insufficient, making them suitable only for parts of a single shape or size. They have poor compatibility with irregularly shaped and fragile materials such as small precision electronic components required for AOI inspection. Furthermore, when changing the feeding material, the machine must be stopped and the track re-adjusted, resulting in low changeover efficiency. Additionally, there is a problem of low integration; feeding and screening are often separate processes. This means that materials must undergo multiple stages, including feeding, transfer, and screening, before entering the subsequent inspection process, which not only prolongs the material flow cycle but also increases the risk of secondary damage to the materials.

[0024] In view of this, this application provides a feeding device in which materials are concentrated in the receiving cavity of a roller feeding assembly and continuously fed onto the feeding end of a screening and conveying assembly from a first opening. Thus, each material is transported by the screening and conveying assembly to the screening and separating assembly. Specifically, the materials are first separated by a separating mechanism, causing them to be sequentially ordered under the action of the screening and conveying assembly and the first horizontal separator, thereby entering the screening mechanism for screening one by one. The second end of the first horizontal separator can move relative to the supporting body, and the screening mechanism can also adapt to the adjustment of the relative position of the second end of the first horizontal separator. This allows for adjustment of the flow width of the separated and screened materials, improving adaptability to materials of different sizes and increasing the flexibility of material screening. Furthermore, by integrating the separation and screening actions into the screening and separating assembly, a single component can complete the process, resulting in a higher degree of integration.

[0025] Please refer to Figures 1 to 4 This application provides a feeding device, including a roller feeding assembly 10, a screening and conveying assembly 20, and a screening and separating assembly 30.

[0026] The roller feeding assembly 10 has a receiving cavity 10a for accommodating materials. The receiving cavity 10a has a first opening 10b and a second opening 10c to communicate with the outside through the first opening 10b and the second opening 10c. The screening and conveying assembly 20 has a feeding end 20a and a discharging end 10b opposite to the feeding end 20a. The feeding end 20a extends into the receiving cavity 10a through the first opening 10b. The screening and separating assembly 30 includes a separating mechanism 31 and a screening mechanism 32 disposed on the screening and conveying assembly 20. The separating mechanism 31 and the screening mechanism 32 are arranged side by side along a first direction X. The separating mechanism 31 includes a support body 311 disposed on the screening and conveying assembly 20 and a first horizontal separating member 312. 1. Extending along the first direction X, the first horizontal separator 312 has a first end 312a and a second end 312b opposite to the first end 312a. The first end 312a of the first horizontal separator 312 abuts against the support body 311, and the second end 312b of the first horizontal separator 312 is movably connected to the support body 311 and can move closer to or further away from the support body 311 along the second direction Y. The screening mechanism 32 extends along the first direction X and can move relative to the screening transmission component 20 in the second direction Y to be flush with the second end 312b. The first direction X is the transmission direction of the screening transmission component 20, and the second direction Y is the width direction of the screening transmission component 20. The first direction X and the second direction Y are perpendicular.

[0027] Understandably, the roller feed assembly 10 is a component used for storage and feeding. The material is randomly concentrated in the receiving cavity 10a of the roller feed assembly 10, and under the action of rolling, the material enters the screening and conveying assembly 20. Here, the receiving cavity 10a is the space of the roller feed assembly 10. The material enters the receiving cavity 10a from the second opening 10c, flows out from the first opening 10b, and is conveyed by the screening and conveying assembly 20. The specific structure of the roller feeding assembly 10 can be referenced as follows: it may include a cylinder with a receiving cavity 10a and a rotating mechanism located on one side of the cylinder. The cylinder has a first opening 10b, which corresponds to the rotating mechanism. The second opening 10c has a different orientation from the first opening 10b. The first opening 10b is oriented in the transmission direction of the screening and conveying assembly 20, while the second opening 10c can be oriented vertically or in the height direction of the cylinder to facilitate subsequent material loading. The rotating mechanism includes a rotating disk rotatably connected to the cylinder and a drive motor that drives the rotating disk to rotate around an axis. The internal space of the rotating disk is connected to the receiving cavity 10a. Thus, the rotating disk lifts the material during its rotation around the axis and climbs along with the rotating disk in the height direction of the cylinder until, after climbing a certain distance, the material falls from the side wall of the rotating disk onto the screening and conveying assembly.

[0028] The screening and conveying assembly 20 is used to transport various materials. Here, the feeding end 20a is the starting point for materials to enter the screening and conveying assembly 20, and the discharging end 10b is the ending point for materials to leave the screening and conveying assembly 20. The specific structure of the screening and conveying assembly 20 can be seen below, which may include a conveyor belt, rollers around which the conveyor belt is wound, and a drive transmission mechanism that drives the rollers to rotate around an axis. The materials are transported on the conveyor belt, that is, the transport path is from the feeding end 20a to the discharging end 10b of the conveyor belt.

[0029] The material separation assembly 30 is used to achieve orderly feeding and screening of materials. The separation mechanism 31 arranges the materials in an orderly manner, meaning that the materials are arranged side-by-side along the conveying direction, with one material to be screened at each position. The screening mechanism 32 screens the current materials based on their posture, structural integrity, and other factors. The supporting body 311 in the separation mechanism 31 is a load-bearing component used to fix the first horizontal separator 312. It should be understood that the incoming material enters the first horizontal separator 312 from the first end 312a. Under the guidance of the first horizontal separator 312 and the combined action of the screening and conveying assembly 20, the materials are arranged orderly along the conveying direction and enter the screening mechanism 32 one by one at the second end 312b of the first horizontal separator 312 for screening.

[0030] Here, the first horizontal separator 312 can be a plate-like structure, a strip-like structure, or a block-like structure. The first horizontal separator 312 should be placed horizontally on the screening and conveying assembly 20. That is, the extension direction of the first horizontal separator 312 forms an angle with the conveying direction. Therefore, the material located on the first horizontal separator 312 is not only subjected to a first force along the first direction X, but also to a second force along the extension direction of the first horizontal separator 312. Thus, under the combined force of the two forces, the materials move relative to each other and are sorted on the first horizontal separator 312. Furthermore, depending on the size and shape of the materials, the distance between the second end 312b of the first horizontal separator 312 and the supporting body 311 can also be adjusted. That is, the direction of the second force is changed, so that the magnitude and direction of the final resultant force are adjusted, thereby achieving the separation and sorting requirements of materials of different specifications.

[0031] The feeding device of the present invention operates as follows: materials are concentrated in the receiving cavity 10a of the roller feeding assembly 10, and continuously fed from the first opening 10b onto the feeding end 20a of the screening and conveying assembly 20. Thus, each material is conveyed by the screening and conveying assembly 20 to the screening and separating assembly 30. Specifically, the materials are first separated by the separating mechanism 31, so that each material is sequentially sorted under the drive of the screening and conveying assembly 20 and the action of the first horizontal separating member 312, and thus enters the screening mechanism 32 for screening one by one. The second end 312b of the first horizontal separating member 312 can move relative to the supporting body 311, and the screening mechanism 32 can also adapt to the adjustment of the relative position of the second end 312b of the first horizontal separating member 312. This allows for adjustment of the flow width of the separated and screened materials, improving adaptability to materials of different sizes and increasing the flexibility of material screening. Furthermore, by integrating the separation and screening actions into the screening and separating assembly 30, a single component can complete the process, resulting in a higher degree of integration.

[0032] Please refer to Figures 1 to 4 In some embodiments, the support body 311 has a first side 311a, and the first horizontal separator 312 has a second side 312c that smoothly transitions to the first side 311a, the second side 312c being used to guide the material.

[0033] Understandably, the side refers to the surface structure erected on the screening and transmission component 20. That is, whether it is the first side 311a or the second side 312c, the plane on which they are located is perpendicular to the transmission plane of the screening and transmission component 20.

[0034] The plane containing the first side 311a should be parallel to the first direction X, and the plane containing the second side 312c should be at an angle to the first direction X. The smooth transition between the second side 312c and the first side 311a means that the material can be smoothly transferred from the support body 311 to the first horizontal separator 312.

[0035] Depending on the actual usage requirements, the second side 312c can be a straight side, where a straight side refers to a surface structure where the angle between the tangent and the first direction X is the same at all points. Alternatively, the second side 312c can be a curved side. Here, a curved side refers to a surface structure where the angle between the tangent and the first direction X varies at different points. Understandably, a curved side has a certain curvature, resulting in different slopes of the tangent at different points, and therefore different angles with the first direction X. The curvature of the curved side can be adjusted according to the size and shape of the material.

[0036] Please refer to Figures 1 to 4 In some embodiments, the first horizontal separating member 312 includes a horizontal fixing part 3121 connected to the support body 311, a horizontal sliding part 3122 slidably connected to the horizontal fixing part 3121, and a horizontal separating part 3123 connected to the horizontal sliding part 3122. The horizontal separating part 3123 has a first end 312a, a second end 312b, and an arcuate side.

[0037] Understandably, the horizontal fixed part 3121 can be provided with a corresponding groove or slide rail, and the horizontal sliding part 3122 is slidably connected to the groove or slide rail. Of course, in order to improve the sliding accuracy, a scale or the like can be engraved on the horizontal fixed part 3121 to quantify the sliding stroke of the horizontal sliding part 3122 relative to the horizontal fixed part 3121.

[0038] The horizontal separation section 3123 is a structural component that comes into direct contact with the material, allowing the materials to be separated in an orderly manner. Here, the horizontal separation section 3123 can be a plate-shaped structure, a strip-shaped structure, or a block-shaped structure, etc.

[0039] Please refer to Figure 4In other embodiments, the first horizontal separating member 312 further includes an angle separating member 313, which is disposed at the second end 312b of the horizontal separating portion 3123. Here, the angle separating member 313 is detachably connected to the horizontal separating portion 3123. For example, the angle separating member 313 can be connected to the horizontal separating portion 3123 by means of plug-in, snap-fit, or threaded connection. Here, the function of the angle separating member 313 is to further increase the separation distance between the materials. The angle separating member 313 has a fourth side surface 313a, which is also smoothly transitioned to the second side surface 312c. The plane containing the fourth side surface 313a forms an angle with the plane containing the second side surface 312c. Thus, after the material is separated from the horizontal separating portion 3123, it will continue to be guided by the fourth side surface 313a of the angle separating member 313, causing the position of the material separating from the first horizontal separating member 312 to change. Since the distance between the second end 312b of the horizontal separation section 3123 and the support body 311 can be adjusted, adding an angle separation member 313 to the second end 312b of the horizontal separation section 3123 can further improve the flexibility of material separation.

[0040] Please refer to Figures 1 to 3 In some embodiments, the screening and separating assembly 30 further includes a second horizontal separating member 314, which is disposed on the first side 311a of the supporting body 311 and located at the first opening 10b. The second horizontal separating member 314 has a third side 314a, which is used to guide the material. The material passes through the third side 314a and the second side 312c in sequence along the first direction X.

[0041] Understandably, in the transmission direction of the screening and conveying assembly 20, the second horizontal separator 314 should be upstream of the first horizontal separator 312, and each material passes through the second horizontal separator 314 before moving to the first horizontal separator 312.

[0042] Here, the third side surface 314a can be a flat surface or an arc surface, and the second horizontal separator 314 is also connected to the support body 311 at one end and away from the support body 311 at the other end. Then, each material can achieve the first separation through the guidance of the third side surface 314a.

[0043] In other embodiments, the second horizontal separator 314 may not be provided, or multiple second horizontal separators 314 of different lengths may be provided between the first opening 10b and the first horizontal separator 312 to achieve multi-stage separation of the incoming material.

[0044] Please refer to Figures 1 to 3In some embodiments, the screening and separating assembly 30 further includes a vertical separating member 315. The vertical separating member 315 includes a vertical fixing part 3151 disposed on the support body 311, a vertical sliding part 3152 slidably connected to the vertical fixing part 3151, and a vertical separating part 3153 connected to the vertical sliding part 3152. The vertical separating part 3153 moves up and down relative to the screening and conveying assembly 20 along a third direction Z, where the third direction Z is a direction perpendicular to the plane where the screening and conveying assembly 20 is located.

[0045] Understandably, the vertical separator 315 is a structural component used to reject materials whose height exceeds a preset height during the transmission process. It should be understood that when the incoming material is small in overall volume, it is prone to accumulation, thereby increasing the separation difficulty for the first horizontal separator 312. Therefore, by "limiting the height", the incoming material can be relatively flattened on the screening and transmission assembly 20. Specifically, the vertical separator 3153 can slide on the vertical fixed part 3151 under the drive of the vertical sliding part 3152, thereby changing the height of the vertical separator 3153 relative to the plane of the screening and transmission assembly 20 in the third direction Z, thus limiting the height of different incoming materials.

[0046] Furthermore, the vertical separation section 3153 is arranged at an angle to the first direction X, and the vertical distribution section is placed horizontally on the screening and conveying assembly 20 to cut off the material on the screening and conveying assembly 20.

[0047] Understandably, when the amount of incoming material is large, the vertical separation section 3153 can also push the excess material away from the screening and conveying assembly 20 during the height-limited laying process, so as to reduce the probability of the incoming material getting stuck in the vertical separation section 3153.

[0048] Please refer to Figures 1 to 3 In some embodiments, the above feeding device further includes a return conveying component 40 which is opposite to the conveying direction of the screening and conveying component 20. The return conveying component 40 and the screening and conveying component 20 are arranged side by side along the second direction Y. The return conveying component 40 extends into the receiving cavity 10a through the first opening 10b to recover the material blocked by the vertical separation part 3153.

[0049] Understandably, the return conveyor assembly 40 is used to return the material rejected from the screening conveyor assembly 20 to the roller feed assembly 10.

[0050] Here, the specific structure of the return transmission assembly 40 can be referred to as follows, which may include a transmission belt, a roller for the transmission belt to be wound, and a drive transmission mechanism that drives the roller to rotate around an axis. One end of the transmission belt extends into the receiving cavity 10a through the first opening 10b.

[0051] Please refer to Figures 1 to 3In some embodiments, the screening mechanism 32 includes a screening main body 321, a visual inspection unit 322 disposed on the screening main body 321, and an air blowing unit 323 connected to the screening main body 321. The screening main body 321 extends along a first direction X and is movable relative to the screening transmission assembly 20 in a second direction Y to be flush with the second end 312b. The screening main body 321 has an air blowing hole 321a connected to the air blowing unit 323. The visual inspection unit 322 and the air blowing hole 321a are arranged sequentially along the first direction X. The return transmission assembly 40 extends along the first direction X to the air blowing hole 321a.

[0052] Understandably, the screening main body 321 is the main body of the screening mechanism 32, used to support the visual inspection unit 322 and other components. Here, the screening main body 321 can be suspended above the screening transmission assembly 20, or it can be rotatably connected to the screening transmission assembly 20. For example, by providing rollers on the screening main body 321, and using the rollers to abut against and roll against the screening transmission assembly 20, the number of support points for the screening main body 321 is increased, which is especially suitable for scenarios where the overall volume of the screening main body 321 is large.

[0053] The visual inspection unit 322 can be a CCD camera, CMOS camera, etc., to acquire the posture of the material after separation.

[0054] The air blowing section 323 is used to remove materials whose posture does not meet the preset requirements from the screening and conveying assembly 20. That is, the vision detection section 322 and the air blowing section 323 are linked. When the vision detection section 322 detects that the posture of the current material is correct, the air blowing section 323 does not work. When the vision detection section 322 detects that the posture of the current material is incorrect, the air blowing section 323 works and generates a high-speed airflow at the air blowing hole 321a to blow the incorrectly positioned material away from the screening and conveying assembly 20 and back into the return conveying assembly 40 for re-feeding, separation and screening.

[0055] Based on actual usage requirements, the number of visual inspection units 322 and air blowing holes 321a is increased, and in the first direction X, the visual inspection units 322 and air blowing holes 321a are alternately set to improve screening efficiency.

[0056] Please refer to Figures 1 to 3 In some embodiments, the screening main body 321 includes a screening main frame 3211 extending along the first direction X and an adjustment main frame 3212 connected to the screening main frame 3211. The screening main frame 3211 is provided with a visual inspection unit 322 and an air blowing hole 321a.
