Description

Technical Field

[0001] This utility model relates to the field of automated processing technology, specifically to a top material lifting mechanism and automated equipment. Background Technology

[0002] In the field of automated equipment processing, automatic material loading is an extremely important action mechanism and a core component for realizing vertical material handling in industrial automation. Its design needs to comprehensively consider load, accuracy, speed and environmental adaptability.

[0003] Existing top-lifting mechanisms have the following drawbacks in some applications of lifting and feeding heavy materials: After a certain period of use, the guide structure of the top-lifting mechanism is prone to deformation, which can directly translate into resistance during the lifting process, further compromising the reliability and smoothness of the mechanism's operation; the movable hinge points of the top-lifting mechanism are almost completely exposed to the outside, making them susceptible to the influence of impurities and moisture in the external environment, which can lead to increased friction at the hinge points and cause points of jamming, shortening the service life of the top-lifting mechanism and requiring more maintenance costs.

[0004] In view of this, it is urgent to design a top material lifting mechanism to solve the defects of the above-mentioned top material lifting mechanisms in practical applications. Utility Model Content

[0005] To solve the above problems, this utility model provides a top material lifting mechanism and automated equipment.

[0006] In a first aspect, this utility model provides a top material lifting mechanism, including a frame, a lifting power source connected to the frame, and a lifting platform driven by the lifting power source. The frame includes a base plate and a top plate, with side plates connected between the base plate and the top plate. Guide rails are connected to the inner sides of the side plates. Slider blocks are connected to both ends of the lifting platform near the top plate, and the sliders are connected to the guide rails. A guide hole is provided in the middle of the top plate, and a guide post is connected to the lifting platform at the position corresponding to the guide hole. The guide post is connected to the guide hole. A first hinge slot is symmetrically opened on the base plate, and a second hinge slot is symmetrically opened on the lifting platform. A first push rod is hinged in the first hinge slot, and a second push rod is hinged in the second hinge slot. A third push rod is symmetrically hinged to the output end of the lifting power source. The first push rod, the second push rod, and the third push rod are hinged at a common point.

[0007] In one possible implementation, a first hinge shaft is connected within the first hinge slot, a second hinge shaft is connected within the second hinge slot, a first end of the first push rod is connected to the first hinge shaft, and a first end of the second push rod is connected to the second hinge shaft.

[0008] In one possible implementation, the output end of the lifting power source is connected to a linkage block, and the two ends of the linkage block are respectively connected to a third hinge shaft, with the first end of the third push rod connected to the third hinge shaft.

[0009] In one possible implementation, the second end of the first push rod is provided with a first U-shaped fork, the second end of the second push rod is provided with a plug-in portion, and the second end of the third push rod is provided with a second U-shaped fork. The plug-in portion is connected to the first U-shaped fork, the first U-shaped fork is connected to the second U-shaped fork, and the plug-in portion, the first U-shaped fork, and the second U-shaped fork are hinged together by a common hinge axis.

[0010] In one possible implementation, a linkage slot is provided on the top plate, and the second push rod is located in the linkage slot.

[0011] In one possible implementation, a slider mounting plate is connected to the lifting platform, the slider mounting plate being located on one side of the second push rod and within the linkage slot, and the slider being connected to the slider mounting plate.

[0012] In one possible implementation, the base plate, the top plate, and the lifting platform are arranged parallel to each other, and the two side plates are arranged parallel to each other.

[0013] In one possible implementation, a guide sleeve is fixedly connected to the center of the top plate, and the guide hole is located inside the guide sleeve.

[0014] In one possible implementation, the lifting power source is one of a hydraulic cylinder, a pneumatic cylinder, and an electric cylinder.

[0015] In a second aspect, an automated device is provided, comprising a device body on which the aforementioned top material lifting mechanism is provided.

[0016] Compared with the prior art, the technical solution provided by this utility model has the following advantages: This technical solution's top-lifting mechanism employs both a slider and guide rail guiding structure and a guide column and guide hole guiding structure. The slider and guide rail guiding structure provides the main large load bearing and guiding functions, exhibiting extremely high lateral rigidity. It can effectively resist the torque generated by load eccentricity and prevent the lifting platform from swaying. The guide column and guide hole guiding structure is located at the center of the mechanism, further constraining the degree of freedom of the lifting platform in the final stroke segment, ensuring precise positioning, and effectively preventing minor overturning of the lifting platform that may occur after long-term use. The dual design greatly enhances the deformation resistance of the entire guiding system. Even with long-term use, the two guiding systems are redundant and mutually supportive, and the deformation will be much smaller than that of a single guiding system, improving the reliability and smoothness of the top-lifting action.

[0017] The design of the first and second hinge slots on the top material lifting mechanism in this technical solution cleverly integrates the hinge points of the first and second push rods into the base plate and lifting platform, effectively preventing dust and debris, reducing direct contact with corrosive media such as water vapor and cutting fluid, and thus significantly extending the service life of the entire top material lifting mechanism.

[0018] This technical solution's top material lifting mechanism adopts a symmetrical layout with the push rods hinged at the same point. Power is output from the lifting power source and directly transmitted to the hinge point through the third push rod. Lifting is then achieved simultaneously through the first and second push rods. The force transmission path is direct and efficient, ensuring that the hinge point only bears tensile and compressive forces during the push rod transmission process, without generating additional bending torque. This reduces unnecessary wear on the push rods and hinge shafts, making the movement smoother and the power loss smaller. At the same time, the frame adopts a frame structure, making the overall structure of the mechanism compact and easy to install and integrate in automated equipment. Attached Figure Description

[0027] In this embodiment, as shown in the appendix Figure 1 Appendix Figure 3 and attached Figure 4 As shown, the lifting power source 2 extends and retracts through its output end, thereby driving the third push rod 6 to move, which in turn causes the first push rod 4 and the second push rod 5 to retract and extend, raising and lowering the lifting platform 3.

The dual design greatly enhances the deformation resistance of the entire guide system. Even with long-term use, the two guide systems are redundant and mutually supportive, and the deformation will be much smaller than that of a single guide system, improving the reliability and smoothness of the top material lifting action.

[0036] In this embodiment, the lifting power source 2 is one of a hydraulic cylinder, a pneumatic cylinder, and an electric cylinder.

[0037] In this embodiment, the top material lifting mechanism 10 adopts a symmetrical layout and is hinged at the same point with the push rod. The power is output from the lifting power source and directly transmitted to the hinge point through the third push rod 6.
