[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] The present invention discloses a precision-positioning automatic loading and unloading elevator for sheet metal, which is mainly used in scenarios where forklifts have difficulty accurately placing stacked sheet metal at the designated position on the elevator platform when loading sheet metal, often requiring repeated adjustments and reducing work efficiency.

[0022] Reference Figure 1 and Figure 2 An automatic loading and unloading elevator for precisely positioned sheet metal includes: a lifting base 4, on which multiple platforms 2 are equally spaced, and a control terminal 1 is provided on one side of the lifting base 4; a positioning and correction component 3, which is disposed on the multiple platforms 2 and is used to correct and position the stacked sheet metal on the platforms 2 so that the sheet metal is accurately loaded to the next stage; and an auxiliary correction component 5, which is disposed inside the corresponding platforms 2 and is used to assist the positioning and correction component 3 in correcting and positioning the sheet metal, and at the same time conveying the positioned sheet metal to the next stage.

[0023] Reference Figures 1-4 In a preferred embodiment, the positioning and correction component 3 includes: a fixing plate 306, two fixing plates 306 are respectively fixedly connected to the outer walls of both ends of the multiple platforms 2, and adjustment holes are respectively opened on opposite sides of the two ends of the two fixing plates 306. The two opposing adjustment holes of one fixing plate 306 are connected to a bidirectional adjusting screw 302 through a bearing, and the two opposing adjustment holes of the other fixing plate 306 are fixedly connected to the same sliding rod 304.

[0024] In this scheme, the positioning and correction component 3 also includes: an adjusting motor 303, which is fixedly connected to the outer wall of one end of one of the fixed plates 306, and the driving end of the adjusting motor 303 is connected to one end of the adjusting bidirectional lead screw 302 through a coupling; and moving blocks 301, with multiple moving blocks 301 being equally spaced on the outer walls of the adjusting bidirectional lead screw 302 and the sliding rod 304, and the two moving blocks 301 on the adjusting bidirectional lead screw 302 being respectively arranged opposite to the two moving blocks 301 on the corresponding sliding rod 304.

[0025] In this solution, the positioning and correction component 3 also includes: a disc shaft 310, multiple disc shafts 310 are respectively connected to the storage holes opened at the upper end of the corresponding moving block 301 through bearings, two fixing rods 308 are fixedly connected to the opposite side of each pair of opposite disc shafts 310, and a rotating hole is opened on the opposite side of each pair of opposite disc shafts 310. The same correction bidirectional lead screw 309 is connected to the two rotating holes through bearings. The correction bidirectional lead screw 309 is located above the two fixing rods 308.

[0026] In this solution, the positioning and correction assembly 3 further includes: sliding blocks 305, multiple sliding blocks 305 are respectively sleeved on the outer walls of two fixed rods 308 and correction bidirectional lead screw 309, and correction positioning plates 307 are fixedly connected to two opposing sliding blocks 305 on the same side; correction motors 311, two correction motors 311 are respectively fixedly connected to one side of the corresponding disc shaft 310, and the driving ends of the two correction motors 311 are connected to one end of the corresponding correction bidirectional lead screw 309 through a coupling; and storage motors 312, two storage motors 312 are respectively fixedly connected to one side of the corresponding moving block 301, and the driving ends of the two storage motors 312 are connected to one end of the corresponding disc shaft 310 through a coupling.

[0027] During the alignment and positioning of the plates, two alignment motors 311 rotate the corresponding alignment bidirectional lead screws 309. Under the action of the two alignment bidirectional lead screws 309, two sets of opposing sliding blocks 305 move closer to each other along the corresponding two fixed rods 308. This allows the two sets of opposing alignment positioning plates 307 to continuously clamp the two ends of the stacked plates. In this process, this action can adapt to plates of different widths. The two sets of alignment positioning plates 307 continuously clamp and push the stacked plates, allowing the originally skewed stacked plates to quickly and accurately return to the required position, thus eliminating the need for frequent adjustments and improving work efficiency. At the same time, the clamping action of the alignment positioning plates 307 makes the stacked plates more neatly enter the next stage, facilitating their use in the next stage. Meanwhile, the storage motor 312 rotates the disc shaft 310, causing multiple alignment positioning plates 307 to rotate into the interior of the corresponding fixed plate 306 for storage, facilitating the subsequent transfer of equipment without affecting other work.

[0028] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 In a preferred embodiment, the auxiliary correction component 5 includes: a rotating shaft 502, multiple rotating shafts 502 are respectively connected to the interior of the corresponding platform 2 through bearings, and multiple conveying rollers 504 are fixedly connected at equal intervals to the outer walls of the multiple rotating shafts 502 located on the same platform 2, and the multiple conveying rollers 504 rotate in the lateral direction; a transmission belt 503 is disposed on the outer wall of the multiple rotating shafts 502 near the interior of the discharge end platform 2; a conveying motor 501 is fixedly connected to the outer wall near the discharge end platform 2, and the drive end of the conveying motor 501 is connected to one end of one of the rotating shafts 502 through a coupling; and an electric telescopic rod 508, multiple electric telescopic rods 508 are disposed at equal intervals on the lower side of the corresponding platform 2, and the telescopic ends of the multiple electric telescopic rods 508 located on the same platform 2 are respectively fixedly connected to the same sliding plate 507 through the lower outer wall of the platform 2, and the multiple sliding plates 507 slide in the sliding groove holes opened inside the corresponding platform 2.

[0029] In this scheme, the auxiliary correction component 5 also includes: a setting frame 506, multiple setting frames 506 are fixedly connected at equal intervals to the corresponding sliding plate 507, and the upper ends of the multiple setting frames 506 are respectively connected to auxiliary rollers 505 through bearings. The multiple auxiliary rollers 505 located on the same platform 2 are staggered with the corresponding multiple conveying rollers 504, and the multiple auxiliary rollers 505 rotate in the longitudinal direction.

[0030] When the board is being positioned and corrected, multiple electric telescopic rods 508 cause multiple sliding plates 507 to rise, which in turn drive multiple auxiliary rollers 505. Under the action of the auxiliary rollers 505, the stacked board moves away from the multiple conveying rollers 504. Since the stacked board only rolls and contacts the multiple auxiliary rollers 505, the subsequent positioning and correction component 3 can only slide longitudinally along with it when positioning and correcting the stacked board. Under the action of friction, the stacked board will not slide laterally, avoiding the risk of the stacked board moving laterally and falling off and damaging the board during the subsequent positioning and correction component 3, thus improving the positioning accuracy of the board.

[0031] Working Principle: When loading the boards, the operator first places the stacked boards to be transferred onto platform 2 using a forklift. Then, multiple electric telescopic rods 508 cause multiple sliding plates 507 to drive multiple auxiliary rollers 505 upwards. Under the action of the auxiliary rollers 505, the stacked boards are moved away from the multiple conveying rollers 504. Since the stacked boards only roll in contact with the multiple auxiliary rollers 505, the subsequent positioning and correction component 3 only slides longitudinally along the stacked boards during positioning and correction. Under the action of friction, the stacked boards will not slide laterally, avoiding the risk of lateral movement and detachment of the stacked boards during subsequent positioning and correction by the positioning and correction component 3, thus improving the positioning accuracy of the boards. Subsequently, two correction motors 311 rotate the corresponding correction bidirectional lead screws 309. Under the action of the two correction bidirectional lead screws 309, two sets of opposing sliding blocks 305 move closer to each other along the corresponding two fixed rods 308, so that the two sets of opposing correction and positioning plates 307 continuously clamp the two ends of the stacked boards. In this process, this action can adapt to boards of different widths. Simultaneously, two sets of correction and positioning plates 307 continuously clamp and push the stacked plates, quickly and accurately correcting the originally skewed stacked plates to the required position, thus eliminating the need for frequent adjustments and improving work efficiency. At the same time, the clamping action of the correction and positioning plates 307 ensures the stacked plates enter the next stage more neatly, facilitating their use in the next stage. Once the stacked plates are precisely positioned, an electric telescopic rod 508 causes multiple sliding plates 507 to drive multiple auxiliary rollers 505 downwards. Under the action of the auxiliary rollers 505, the stacked plates are brought closer to multiple conveyor rollers 505. 4. Until the stacked plates are only in rolling contact with multiple conveyor rollers 504, the conveyor motor 501 drives the conveyor rollers 504 to rotate and transport the stacked plates to the next stage. When no work is required, the correction motor 311 moves the two sliding blocks 305 away from each other until they contact the corresponding disc shaft 310. Then, the storage motor 312 rotates the disc shaft 310. Under this action, multiple correction positioning plates 307 rotate into the interior of the corresponding fixing plate 306 for storage, which facilitates the subsequent transfer of equipment without affecting other work.

[0032] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
