Description

Technical Field

[0001] The utility model relates to the technical field of fastener feeding, in particular to a material picking and posture adjusting mechanism. Background Art

[0002] In automated production lines, precise material handling and posture adjustment are critical to ensuring the quality of subsequent assembly or processing. This is particularly true for small fasteners such as rods, screws, rivets, and pins. Due to their structural characteristics and the potential for inconsistent posture and chaotic arrangement during production, precise material handling and posture adjustment present a technical challenge.

[0003] Existing material picking mechanisms mostly use vibration plates, robotic arms, or vacuum nozzles to separate and pick up materials. However, these traditional methods have many shortcomings in practical applications:

[0004] Low picking accuracy: When the vibrating plate separates materials, it is often difficult to effectively control the posture and arrangement of screws, rivets, pins, etc. with irregular shapes or large size differences, resulting in inconsistent material postures during the picking process, affecting the accuracy and efficiency of subsequent assembly.

[0005] Poor adaptability: Traditional picking mechanisms are often designed for materials of specific specifications. When it is necessary to process materials of different sizes or shapes, the mechanism components need to be replaced or adjusted, which increases the complexity and cost of the operation.

[0006] Limited detection methods: During the material picking process, real-time detection of the material's size and posture is key to improving picking accuracy. However, most existing mechanisms lack effective detection methods or have low detection accuracy, making it difficult to meet the needs of high-precision production.

[0007] Low degree of automation: Some material picking mechanisms still rely on manual intervention to adjust the posture and pick up materials, which not only reduces production efficiency but also increases labor costs and quality risks.

[0008] To this end, we propose a material picking and posture adjustment mechanism. Utility Model Content

DETAILED DESCRIPTION

[0043] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.

[0044] like Figure 1-Figure 4 The embodiment shown in the figure discloses a material picking and posture adjustment mechanism, the structure of which includes

[0045] The material picking and posture adjustment mechanism includes a hollow disc 100, and the disc 100 is provided with at least two groups of openings arranged along the diameter direction. The two openings in the same group are on the same diameter. The two groups of openings each include an open side. The other sides of the two groups of openings are connected to a vacuum generator 400 and an air blowing interface 500 respectively. The opening in the same group as the vacuum generator 400 is connected to a suction pipe 200, and the opening in the same group as the air blowing interface 500 is connected to a blowing pipe 300. There is a rotating channel 101, which is driven to rotate by a rotating device 600 and is respectively connected to the suction pipe 200 and the blowing pipe 300. When the rotating channel 101 connects the vacuum generator 400 to the suction pipe 200, the vacuum generator 400 can provide negative pressure to drive the material to move into the rotating channel 101. When the rotating channel 101 connects the blowing interface 500 to the blowing pipe 300, the blowing interface 500 blows air into the blowing pipe 300 to blow out the material.

[0046] In this embodiment, the materials include rod-shaped workpieces, columnar workpieces, screws, bolts, rivets, and screws;

[0047] In order to avoid interference in equipment installation, a certain angle is set between the two groups of openings. In this embodiment, the angle between the two groups of openings is 90 degrees. In actual work, the size of the angle is not limited, and they can be arranged freely as long as there is no interference in equipment installation.

[0048] In another embodiment, the number of groups of openings on the disc 100 is greater than 2, such as 3, 4, 5, ..., and at least one group of openings is connected to a vacuum generator 400 for picking up materials when docking with the corresponding suction pipe 200. At the same time, if there are other groups of openings, there are also vacuum generators 400, which can achieve material picking in multiple directions. Therefore, the number of groups containing vacuum generators 400 is not fixed, and is at least greater than 1, and can also be 2, 3, 4, or 5 groups. However, it is necessary to ensure that at least one group of openings is reserved for the blowing interface 500 to achieve material distribution.

[0049] However, under normal circumstances, the number of opening groups containing the vacuum generator 400 is 1 group, while the number of groups containing the air blowing interface 500 is larger, usually greater than or equal to 1 group, such as 3 groups, 4 groups, 5 groups... At this time, after picking up the material, the material is distributed through different air blowing interfaces 500, thereby improving the distribution efficiency.

[0050] Specifically, the suction pipe 200 is coaxially arranged with the vacuum suction port of the vacuum generator 400. The vacuum suction port of the vacuum generator 400 is smaller than the inner diameter of the rotating channel 101 to prevent the material from being sucked into the vacuum suction port. The air pressure detection sensor is installed on the vacuum generator 400 to detect the pressure change of the vacuum generator 400 and determine whether the material has reached the rotating channel 101. The rotating channel 101 is connected to the rotating device 600. When the rotating channel 101 rotates to coincide with the suction pipe 200, it also coincides with the vacuum generator 400. The vacuum generator 400 generates a vacuum to suck the material into the rotating channel 101. When the air pressure detection sensor detects the air pressure change, the rotating device 600 drives the rotating channel 101 to rotate until the blowing pipe 300 and the blowing interface 500 coincide. The material picking and posture adjustment mechanism moves to the position of the blowing material part 30 and coincides with it. Finally, the blowing interface 500 passes compressed air to blow the material from the rotating channel 101 into the blowing material part 30.

[0051] In another embodiment, Figure 2 As shown, in order to achieve the detection effect of the material, the structure of the suction pipe 200 is specially designed. In this embodiment, the suction pipe 200 includes a fixed material pipe 201, a movable material pipe 202, a push-pull cylinder 700, a limit cylinder 800, a contact block 901, an elastic ring 902 and a limit block 1000. The push-pull cylinder 700 and the limit cylinder 800 are fixed on the fixed material pipe 201, and the movable material pipe 202 is slidably sleeved on the fixed material pipe 201. The outer edge of the feeding port of the fixed material pipe 201 is chamfered. The push-pull cylinder 700 is connected to the side wall of the fixed material pipe 201 through a bracket. The piston rod of the push-pull cylinder 700 is connected to the limit block 1000. The limit block 1000 is installed on the movable material pipe 202. As the push-pull cylinder 700 is started, it can drive the movable material pipe 202 to move telescopically on the fixed material pipe 201.

[0052] In another embodiment, a limiting cylinder 800 is further connected to the fixed material tube 201 , and the limiting cylinder 800 can contact the limiting block 1000 by extending and retracting, thereby limiting the fixed material tube 201 and the moving material tube 202 .

[0053] like Figure 4As shown, a positioning structure 900 is provided on the side wall of the feed port of the moving material tube 202, which can temporarily fix the material and then detect the fixed material. The positioning structure 900 includes at least one contact block 901 and an elastic ring 902. There is at least one through hole at the beginning, and a contact block 901 that moves axially along the through hole is provided in the through hole. The moving material tube 202 is provided with an elastic ring 902 that drives the contact block 901 to move toward the inner cavity of the moving material tube 202. The elastic ring 902 is a material picking and posture adjustment mechanism such as an O-ring, a rubber band or a stretch spring ring. The contact block 901 extends into the inner cavity of the moving material tube 202 under the pressure of the elastic ring 902 and limits the upward movement of the material.

[0054] In this embodiment, the contact block 901 is a steel ball, and its structure needs to meet the requirements of shrinkage under the action of the dosing tube 201. The shapes of the contact block 901 include oval, wedge, and triangle.

[0055] like Figure 4 As shown, in another embodiment, a visual size detection unit 1100 is further provided on the side of the moving material pipe 202 at the point where the limiting cylinder 800 limits the position. This unit is used to detect the size and type of the material. The visual size detection unit 1100 is electrically connected to the rotating device 600 to facilitate the corresponding allocation of materials of different sizes and types. The purpose of restricting the movement of the material by the contact block 901 is also to provide a detection position for the visual size detection unit 1100.

[0056] In this embodiment, the diameter of the through hole on one side of the moving material tube 202 is smaller than the diameter of the contact block 901, so as to prevent the contact block 901 from completely entering the moving material tube 202, and facilitate the fixed material tube 201 to block the contact block 901 back into the through hole through resistance, so as to facilitate the passage of subsequent materials. When the vacuum generator 400 passes the vacuum into the fixed material tube 201 through the suction tube 200, the material is first blocked by the contact block 901 in the moving material tube 202, the limit cylinder 800 extends the piston rod, the push-pull cylinder 700 retracts the moving material tube 202, and the limit block 1000 is supported by the cylinder to limit Finally (from the material picking station to the inspection station), the suction tube 200 is moved to the visual size detection part 1100 to detect the material size on the moving material tube 202, the limit cylinder 800 and the push-pull cylinder 700 retract the piston rod, and the chamfer of the feed inlet of the fixed material tube 201 pushes the contact block 901 outward from the inner wall of the moving material tube 202. Since the material is continuously attracted by the vacuum, after being sucked into the fixed material tube 201, the push-pull cylinder 700 and the limit cylinder 800 are reset, and the contact block 901 is squeezed by the elastic ring 902 and reset to the inner wall of the moving material tube 202, which is convenient for reuse.

[0057] This embodiment provides a material pickup and posture adjustment mechanism. Through the provision of a rotating channel 101 and a rotating device 600, the mechanism achieves posture adjustment and conveying of materials. Furthermore, the unique design of the suction tube 200 enables precise positioning and detection of materials, improving the accuracy and stability of the system. Furthermore, through coordination with the blowing and conveying unit 30, the material is automatically blown and conveyed, enhancing the system's automation level and production efficiency. This mechanism also enables automatic posture adjustment and conveying of materials, improving production efficiency and accuracy.

[0058] Furthermore, through the specialized structural design of the suction pipe 200, including the addition of components such as the fixed material pipe 201, the movable material pipe 202, the push-pull cylinder 700, and the limit cylinder 800, precise material control and detection are achieved. The provision of the contact block 901 and the elastic ring 902 temporarily blocks and positions the material, facilitating size detection by the visual size detection unit 1100. This design also enables automatic material suction and delivery, precise material control and detection, and improves the system's automation and production efficiency.
