Description

Technical Field

[0001] This utility model relates to the field of automated material conveying equipment technology, specifically to a lifting feeding device for orderly material supply, which is suitable for production scenarios requiring precise material supply, such as electronics and machining. Background Technology

[0002] In the field of automated production, the orderly supply of materials is a key factor in ensuring the efficient operation of the production line. Currently, common feeding devices mainly include vibratory feeders, belt conveyors, and lifting feeders. Among them, lifting feeders are widely used in production scenarios with limited space because they can achieve vertical material transport.

[0003] Traditional lifting-type feeding devices typically use a single lifting plate or a simple stepped structure for material conveying, which has the following technical drawbacks: First, when the material is irregularly shaped or tightly stacked, a single lifting structure is prone to causing material jamming, making continuous and stable feeding impossible; second, the posture of the material is difficult to control during the lifting process, requiring additional complex orientation mechanisms, which increases equipment costs and failure rates; third, the coordination accuracy between the material dispersing mechanism and the vision positioning system is insufficient, especially in flexible production scenarios, making it difficult to meet the high-precision material handling requirements; fourth, most devices are fixedly installed, lacking flexible movement and positioning functions, and cannot adapt to rapid adjustments in production line layout. Utility Model Content

[0004] This invention provides a feeding device that enables stepped lifting, precise positioning, and flexible movement of materials, solving the problems of material stacking and jamming, insufficient positioning accuracy, and inconvenient movement in traditional feeding equipment.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A lifting feeding device includes a body, a hopper and a material dispersing mechanism disposed on the body, and a material lifting mechanism disposed within the body; the lifting working surface of the material lifting mechanism is inclined toward the material dispersing mechanism and extends into the hopper, for conveying materials to the material dispersing mechanism step by step.

[0007] Furthermore, the material lifting mechanism includes:

[0008] The base frame is fixedly mounted on the base plate of the machine body;

[0009] A stepped lifting assembly is installed on the base frame near the silo, with its lifting working surface inclined toward the material dispersing mechanism inside the silo.

[0010] A power unit is located on the side of the base frame away from the hopper, and is used to drive the stepped lifting assembly to lift and convey materials from bottom to top.

[0011] Furthermore, the stepped lifting assembly includes side frames symmetrically arranged on the base frame, and several fixed blocks and movable blocks arranged on the inclined side of the side frames. The fixed blocks are vertically fixedly installed on the inclined side of the side frames, and the movable blocks are vertically slidably engaged with the side frames, with the movable blocks located between two adjacent fixed blocks. Each movable block is driven by the power assembly to move up and down in the vertical direction to cooperate with the fixed blocks to form a stepped lifting engagement.

[0012] Furthermore, the top surface of each of the fixed blocks and movable blocks is set as an inclined surface, and the inclination direction of the inclined surface is opposite to the direction of the inclined side of the side frame; when the movable block rises vertically to a height above the top surface of the adjacent fixed block, the material slides down the inclined surface onto the inclined surface of the fixed block, realizing a stepped lifting.

[0013] Furthermore, the power assembly includes:

[0014] The lifting frame abuts against the bottom of each of the movable blocks and is vertically guided by the slider rail module and set inside the side frame;

[0015] The lifting component is fixedly connected to the lifting frame;

[0016] A power source is used to drive the lifting component and the lifting frame to move up and down as a whole; the power source is one or more of a motor, cylinder, hydraulic cylinder, and electric push rod.

[0017] Furthermore, when the power source is an electric motor, the output shaft of the electric motor is connected to a rotating wheel, and the circumferential side of the rotating wheel and the lower end of the push rod form a rotating pair through a pin. The upper end of the push rod is rotatably connected to the lifting component, forming a crank-connecting rod transmission structure.

[0018] Furthermore, the upper end of the stepped lifting assembly is provided with a material storage mechanism for temporarily storing materials. The material storage mechanism is rotatably provided with a flip plate near the discharge port of the material dispersing mechanism. The flip plate is driven by a flipping motor to rotate and open or close the discharge port.

[0019] Furthermore, the material dispersing mechanism is a flexible vibrating plate. The lifted material falls into the flexible vibrating plate, the surface of which is made of a light-transmitting material, and a light source is installed inside the flexible vibrating plate. The flexible vibrating plate gathers, disperses, or jumps and flips the material by vibration, and the material is positioned by an external visual recognition system, and then picked up by an external gripping device.

[0020] Furthermore, a caster lifting mechanism is provided at the bottom of the machine body, and support feet are correspondingly provided at the corners of the bottom of the machine body. The caster lifting mechanism includes:

[0021] The caster lifting platform is vertically movable on the top surface of the base plate;

[0022] The swivel casters are vertically mounted at the four corners of the caster lifting plate via a sliding rod assembly. The sliding rod assembly is connected to the base plate via a linear bearing to form a sliding pair.

[0023] The caster lifting drive assembly is used to drive the caster lifting plate to move vertically in a straight line, so as to adjust the extension height of the swivel caster.

[0024] Furthermore, the caster lifting drive assembly includes a turbine lift mechanism disposed on the top surface of the base plate and a handwheel rotatably disposed on the outside of the machine body. The handwheel is driven by the turbine lift mechanism through a transmission shaft, and the height of the caster lifting plate is adjusted by rotating the handwheel to drive the turbine lift mechanism.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] This utility model consists of a body, a hopper, a material dispersing mechanism, and a material lifting mechanism. The material lifting mechanism, through the cooperation of a base frame, a stepped lifting component, and a power component, forms a stepped lifting structure between the movable block and the fixed block, conveying the material step by step to a temporary storage mechanism. The temporary storage mechanism controls the material discharge through a flip plate. The material dispersing mechanism uses a flexible vibrating plate combined with a light-transmitting material and a light source, along with a vision system to achieve material positioning. This device avoids material stacking and jamming through the stepped lifting structure, and the flexible vibrating plate and vision system improve the accuracy of material orientation positioning, effectively solving the problems of low conveying efficiency and inaccurate positioning in traditional feeding devices. It is suitable for high-precision automated production scenarios. Attached Figure Description

[0034] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "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 utility model 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 utility model.

[0036] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," 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 utility model according to the specific circumstances.

[0037] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] like Figure 1-6As shown, this utility model proposes a lifting feeding device, including a body 1, a hopper 2 and a material dispersing mechanism 5 disposed in the body 1, and a material lifting mechanism 3 located inside the body 1. The bottom of the body 1 is provided with a caster lifting mechanism 6 to facilitate the movement and fixation of the device.

[0039] The hopper 2 has an inverted cone shape, which facilitates the sliding of materials and cooperates with the material lifting mechanism 3.

[0040] The material lifting mechanism 3 includes a base frame 31 fixed to the base plate 11, a stepped lifting assembly located on the side of the base frame 31 near the hopper 2, and a power assembly located on the other side of the base frame 31. The lifting components of the stepped lifting assembly are arranged inclined in the hopper 2 towards the material dispersing mechanism 5, and are driven by the power assembly to convey materials upward.

[0041] The stepped lifting assembly includes side frames 32 symmetrically arranged on the base frame 31, and fixed blocks 33 and movable blocks 34 installed on the inclined sides of the side frames 32. The fixed blocks 33 are vertically fixed to the inclined sides of the side frames 32, and the movable blocks 34 are vertically slidably engaged with the side frames 32 and located between adjacent fixed blocks 33. The movable blocks 34 are driven to move up and down by a power assembly, forming a stepped lifting structure with the fixed blocks 33.

[0042] Both the fixed block 33 and the movable block 34 have inclined surfaces on their top surfaces, with the inclination direction opposite to that of the side frame 32. When the movable block 34 rises to be level with the top surface of the adjacent fixed block 33, the material slides down the inclined surface to the inclined surface of the fixed block 33, achieving a stepped lifting effect.

[0043] The power assembly includes a lifting frame 35 that abuts against the bottom of the movable block 34, the lifting frame 35 being vertically guided inside the side frame 32 via a slider rail module; a lifting component 39 fixedly connected to the lifting frame 35; and a power source for driving the lifting component 39 and the lifting frame 35 to move up and down. The power source can be a motor, cylinder, etc. Taking the motor 36 as an example, its output shaft is connected to a rotating wheel 37, the rotating wheel 37 being rotatably connected to the lower end of a push rod 38 via a pin, and the upper end of the push rod 38 being rotatably connected to the lifting component 39, forming a crank-connecting rod transmission.

[0044] The material storage mechanism 4 is located at the upper end of the stepped lifting assembly. It has a flip plate 42 near the discharge port of the material dispersing mechanism 5. The flip plate 42 is driven to rotate by the flip motor 41 to control the opening and closing of the discharge port.

[0045] The material dispersing mechanism 5 is a flexible vibrating plate with a translucent surface and an internal light source. The flexible vibrating plate gathers, disperses, or jumps and flips materials by vibration, and works with an external vision system to locate the material's direction, so that the gripping device can pick up the material.

[0046] The bottom corner of the machine body 1 is provided with supporting feet 12. The caster lifting mechanism 6 includes a caster lifting plate 62 that is vertically movable on the top surface of the base plate 11. The four corners of the caster lifting plate 62 are equipped with swivel casters 61 via sliding rod assemblies. The sliding rod assemblies are slidably connected to the base plate 11 via linear bearings. The caster lifting drive assembly includes a turbine lift 63 and a handwheel 65. The handwheel 65 is driven by the turbine lift 63 via a drive shaft 64. Rotating the handwheel can adjust the extension height of the swivel casters 61.

[0047] Specifically, the specific implementation process of this utility model is as follows:

[0048] Initial state: The movable block 34 is in the lowest position, and the material is piled on the fixed block 33 and the movable block 34 at the bottom of the silo 2.

[0049] Lifting process: The motor 36 starts, driving the wheel 37 to rotate, which in turn drives the lifting frame 35 to move upward through the crank-connecting rod mechanism, and the movable block 34 moves upward accordingly.

[0050] Step-by-step transfer: When the movable block 34 rises above the top surface of the adjacent fixed block 33, the inclined surfaces of the two blocks form a continuous slope. The material slides down the slope from the movable block 34 to the fixed block 33, completing the first stage of lifting. After the movable block 34 descends, the next set of movable blocks repeats the action, and the material gradually rises to the material storage mechanism 4.

[0051] Material storage mechanism 4 receives the lifted material. Tilting motor 41 drives tilting plate 42 to rotate, opening the discharge port and causing the material to fall into the flexible vibrating plate. The flexible vibrating plate vibrates to distribute the material evenly. An internal light source, in conjunction with a vision system, identifies the material's posture, and after positioning, the gripping device picks it up.

[0052] When the device needs to be moved, rotate the handwheel 65, which drives the turbine lift 63 via the drive shaft 64 to push the caster lifting plate 62 up, the swivel caster 61 extends out of the support body 1, and the support feet 12 are off the ground; after positioning, rotate the handwheel in the opposite direction, the caster lifting plate 62 descends, the swivel caster 61 retracts, and the support feet 12 touch the ground and are fixed.

[0053] As a further optional embodiment, the power component can be a cylinder, a hydraulic cylinder, or an electric actuator. For example, when a cylinder is used, the piston rod is extended and retracted by a solenoid valve to drive the lifting component 39. The light-transmitting surface of the flexible vibrating plate can be used with different wavelength light sources to optimize the visual recognition effect of materials such as metals and plastics.

[0054] This invention utilizes a combination of fixed and movable blocks to achieve step-by-step material lifting, preventing stacking and jamming, and improving conveying stability. A flexible vibrating plate combined with a vision system allows for precise material positioning, meeting high-precision material handling requirements and making it suitable for feeding irregularly shaped parts. A caster lifting mechanism allows for quick switching between moving and fixed states, while support feet ensure stability during operation, enhancing equipment adaptability. A material storage mechanism uses a tilting plate to control discharging, achieving quantitative feeding and improving feeding efficiency in conjunction with the lifting mechanism.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0056] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
