By setting up cylinders, roller conveyors, gears and drive motors, it can realize the automated storage and retrieval of goods. It does not require manpower to carry goods to a designated location for storage, which reduces the cost of storing and retrieving goods and the risk of workers working at high altitudes.

[0013] As a preferred embodiment of the present invention, an avoidance groove is provided on the lower surface of the inner end of the trapezoidal block.

[0014] A method for automating a three-dimensional storage device, the method comprising the following steps: S1. Before storing goods, the storage and retrieval mechanism is located in the middle of the bottom of the storage cabinet, the second spring is in a natural state, and the clamping block on the outer wedge block extends above the load-bearing plate through the active area. When storing goods, the goods are placed on the upper surfaces of the two load-bearing plates; S2. Under the action of the gravity of the goods, the two load-bearing plates and the outer wedge-shaped block are squeezed to move downward synchronously. At this time, the four first springs, the outer telescopic rod and the outer third spring are all compressed. In this process, the two L-shaped clamping plates are synchronously turned inward with the rotating shaft of the L-shaped clamping plate as the center under the action of a number of T-shaped rotating blocks, thereby clamping and limiting the two sides of the goods; at the same time, the outer wedge-shaped block drives the clamping block on it to move downward for a distance synchronously, thereby squeezing the trapezoidal block to move in the direction close to the inner wedge block. At this time, the lower end of the trapezoidal block will squeeze the second spring, and the inner wedge block drives the clamping block above it to move upward under the action of the trapezoidal block and the inner telescopic rod until the clamping block extends out of the load-bearing plate. Under the synchronous limiting of the two L-shaped clamping plates and the two clamping blocks, the goods are stabilized and fixed; S3, then control the start of the motor through the control panel, so that the motor drives the electric slide connected to the screw rod to move upward, and when the access mechanism moves to the specified height, control the start of the electric slide through the control panel, so that the electric slide drives the electric slider to move left and right, until the access mechanism moves to the corresponding storage compartment; S4, start the second electric push rod to drive the moving plate to move toward the position close to the storage compartment, and the movement of the moving plate synchronously drives the two top blocks to move. As the top blocks continue to enter, the top blocks will push the L-shaped clamping plate to slowly reset. When the upper surface plane of the top block initially contacts the lower surface of the L-shaped clamping plate, the L-shaped clamping plate returns to its original position, thereby driving the two bearing plates to reset. At this time, the outer wedge block also returns to its original position without being affected by gravity. The second spring reset drives the inner wedge block to reset. The clamping block above the inner wedge block moves down to below the bearing plate, and the bearing plate is flush with the partition on the storage compartment; S5, then the second electric push rod continues to push the moving block forward, the planes on the upper surfaces of the two top blocks continue to slide forward on the lower surface of the L-shaped clamping plate, and the outer clamping blocks push the goods toward the storage compartment. When the outermost plane on the upper surface of the top block moves to the innermost part of the lower surface of the L-shaped clamping plate, the outermost clamping blocks just push the goods into the storage compartment to complete the storage of the goods; S6. After the goods are stored, the load-bearing plate is reset under the action of the first springs, and the second electric push rod drives the movable plate to move in the opposite direction, and the movable plate is pulled out of the storage compartment; S7, when picking up goods, the storage and retrieval mechanism is moved to the picking position under the cooperation of the motor, the electric slide plate and the electric slider, so that the carrying plate is lower than the position of the storage compartment partition, and then the first electric push rod is started to push the carrying frame to move a short distance in the direction of the storage cabinet, which is smaller than the distance of the gap at the front end of the carrying frame, and then the second electric push rod is started to drive the moving plate to move, so that the moving plate is completely under the partition, and the outer clamping block is just close to the outer side of the goods; S8. Start the motor to drive the load-bearing frame to move upward a short distance. At this time, the partition will press down the front ends of the two load-bearing plates, thereby driving the outer wedge block to move downward, and then driving the clamping block on the inner wedge block to extend out from above the partition through the movable groove. Finally, start the second electric push rod again to drive the movable plate to reset. At this time, the goods above the partition are pulled onto the two load-bearing plates under the action of the two clamping blocks and the second electric push rod. Then start the first electric push rod to pull the load-bearing frame out of the storage cabinet, and use the motor to transport the goods to the bottom of the storage cabinet for easy retrieval.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention can achieve the purpose of storing and retrieving goods and improve the storage and retrieval efficiency by setting the storage and retrieval mechanism; the cooperation of the frame structure and the clamping structure enables the goods to be clamped and fixed by two L-shaped clamping plates and two clamping blocks under the action of their own gravity, thereby enhancing the stability of goods storage and retrieval, and effectively avoiding the occurrence of goods falling during the storage and retrieval process, thereby preventing damage to the goods and danger to the staff.

[0016] 2. The present invention facilitates the first electric push rod to drive the bearing frame to extend into the storage cabinet through the arrangement of the first T-slot, the first electric push rod and the T-block. Then, under the action of the motor, the partition on the storage cabinet squeezes the bearing plate to complete the upward movement of the inner wedge block, which is conducive to the removal of goods.

[0022] Specifically, the setting of the storage and retrieval mechanism 5 can serve the purpose of storing and retrieving goods and improve the storage and retrieval efficiency; the cooperation of the frame structure 501 and the clamping structure 503 enables the goods to be clamped and fixed by the two L-shaped clamps 5012 and the two clamping blocks 5034 under the action of their own gravity, thereby enhancing the stability of goods storage and retrieval, and effectively avoiding the occurrence of goods falling during the storage and retrieval process, thereby preventing damage to the goods and danger to the staff.

[0023] like Figure 1 - Figure 4As shown, the storage cabinet 1 is provided with a plurality of storage compartments, each of which is provided with a movable groove 101 and a through groove 102 , and the movable groove 101 corresponds to the movable area left between the two bearing plates 5013 .

[0024] It should be noted that the setting of the movable groove 101 and the movable area provides a movable space for the two clamping blocks 5034, which is conducive to the clamping blocks 5034 to store and retrieve goods in the movable groove 101; the setting of the through groove 102 facilitates the extension of the movable plate 5022.

[0025] like Figure 1 , Figure 2 As shown, the lifting mechanism 3 includes a screw rod 301 and a limit rod 302, both of which are arranged on the front side of the storage cabinet 1, the screw rod 301 is rotatably installed on the left side of the storage cabinet 1, the limit rod 302 is fixedly connected to the right side of the storage cabinet 1, and a motor 303 is fixedly installed on the left side of the storage cabinet 1, and the output shaft of the motor 303 is fixedly connected to the upper end of the screw rod 301.

[0026] like Figure 2 , Figure 4 As shown, the sliding mechanism 4 includes an electric skateboard 401, one end of the electric skateboard 401 is threadedly connected to the lead screw 301, and the other end of the electric skateboard 401 slides on the outer surface of the limit rod 302. A slide rail 4011 is provided in the middle of the inner side of the electric skateboard 401, and a first T-slot 4012 is provided on the electric skateboard 401 on both sides of the slide rail 4011. An electric slider 402 is provided in the slide rail 4011, and a first electric push rod 403 is fixedly installed in the electric slider 402, and the output end of the first electric push rod 403 is fixedly connected to the outer side of the supporting frame 5011.

[0027] like Figure 2 , Figure 4 As shown, two T-blocks 504 are fixedly connected to the outer side of the carrying frame 5011 , and the two T-blocks 504 move in each first T-slot 4012 .

[0028] It should be noted that the T-block 504 can move forward and backward in the first T-slot 4012 , so as not to hinder the first electric push rod 403 from driving the carrying frame 5011 to extend.

[0029] like Figure 4 , Figure 5 , Figure 6 As shown, second T-slots 50121 are provided on both sides of the upper surface of each L-shaped clamping plate 5012 , and T-shaped rotating blocks 5014 are rotatably connected to both sides of the lower surface of each supporting plate 5013 , and the T-shaped rotating blocks 5014 slide along the inner walls of the second T-slots 50121 .

[0030] Specifically, when the carrying plate 5013 moves downward, it drives several T-shaped rotating blocks 5014 to move downward. At this time, the T-shaped rotating blocks 5014 squeeze the L-shaped clamping plates 5012 downward while sliding along the inner wall of the second T-shaped slots 50121 until the two L-shaped clamping plates 5012 clamp the two sides of the cargo, thereby improving the stability of the cargo.

[0031] like Figure 4 , Figure 5 As shown, the two top blocks 5023 are both located at the outer ends of the moving plate 5022 , and two slide grooves 50221 are provided in the middle of the upper surface of the moving plate 5022 . The two ends of the lower surface of the trapezoidal block 5035 slide on the inner walls of the two slide grooves 50221 .

[0032] It should be noted that the L-shaped clamping plate 5012 is slowly pushed upward by the inclined surfaces of the two top blocks 5023 until the lower surface of the L-shaped clamping plate 5012 contacts the upper surface of the top block 5023 , thereby completing the resetting of the L-shaped clamping plate 5012 .

[0033] like Figure 3 , Figure 5 , Figure 8 As shown, the wedge block 5033 located on the inner side is adapted to the active area, the width of the wedge block 5033 located on the outer side is greater than the width of the active area, and both wedge blocks 5033 are located below the supporting plate 5013 .

[0034] It should be noted that the width of the outer wedge block 5033 is set to facilitate the bearing plate 5013 to squeeze it, thereby driving the inner wedge block 5033 to move upward, so that the two clamping blocks 5034 clamp the two ends of the goods; like Figure 8 As shown, a avoidance groove 50351 is provided on the lower surface of the inner end of the trapezoidal block 5035 .

[0035] It should be noted that the setting of the avoidance groove 50351 makes it easier for the trapezoidal block 5035 to push the inner wedge block 5033 smoothly without being affected by the inner telescopic rod 5031 and the inner third spring 5032, thereby completing the upward movement of the inner wedge block 5033.

[0036] A method for automating a three-dimensional storage device comprises the following steps: S1. Before storing goods, the storage and retrieval mechanism 5 is located at the middle of the bottom of the storage cabinet 1, the second spring 5025 is in a natural state, and the clamping block 5034 on the outer wedge block 5033 extends above the carrying plate 5013 through the active area. When storing goods, the goods are placed on the upper surfaces of the two carrying plates 5013; S2. Under the action of the weight of the goods, the two bearing plates 5013 and the outer wedge block 5033 are squeezed to move downward synchronously. At this time, the four first springs 5015, the outer telescopic rod 5031 and the outer third spring 5032 are all compressed. In this process, the two L-shaped clamping plates 5012 are synchronously turned inward with the rotation axis of the L-shaped clamping plates 5012 as the center under the action of the several T-shaped rotating blocks 5014, thereby clamping and limiting the two sides of the goods; at the same time, the outer wedge block 5033 drives the clamping blocks on it The inner wedge block 5034 moves downward for a distance synchronously, thereby squeezing the trapezoidal block 5035 to move toward the inner wedge block 5033. At this time, the lower end of the trapezoidal block 5035 squeezes the second spring 5025. The inner wedge block 5033 drives the clamping block 5034 above it to move upward under the action of the trapezoidal block 5035 and the inner telescopic rod 5031, until the clamping block 5034 extends above the carrying plate 5013. Under the synchronous limit of the two L-shaped clamping plates 5012 and the two clamping blocks 5034, the cargo is stabilized and fixed. S3, then the control panel 2 is used to control the start of the motor 303, so that the motor 303 drives the electric slide 401 threadedly connected to the screw rod 301 to move upward. When the access mechanism 5 moves to a specified height, the control panel 2 is used to control the start of the electric slide 401, so that the electric slide 401 drives the electric slider 402 to move left and right, until the access mechanism 5 moves to the corresponding storage compartment; S4, start the second electric push rod 5021 to drive the moving plate 5022 to move towards the position close to the storage compartment, and the movement of the moving plate 5022 synchronously drives the two top blocks 5023 to move. As the top block 5023 continues to enter, the top block 5023 will push the L-shaped clamping plate 5012 to slowly reset. When the upper surface plane of the top block 5023 initially contacts the lower surface of the L-shaped clamping plate 5012, the L-shaped clamping plate 5012 returns to its original position, thereby driving the two bearing plates 5013 to reset. At this time, the outer wedge block 5033 also returns to its original position without being affected by gravity. The second spring 5025 resets and drives the inner wedge block 5033 to reset. The clamping block 5034 above the inner wedge block 5033 moves down to below the bearing plate 5013, and the bearing plate 5013 is flush with the partition on the storage compartment; S5, then the second electric push rod 5021 continues to push the moving block forward, the planes of the upper surfaces of the two top blocks 5023 continue to slide forward on the lower surface of the L-shaped clamping plate 5012, and the outer clamping blocks 5034 push the goods toward the storage compartment. When the outermost plane of the upper surface of the top block 5023 moves to the innermost part of the lower surface of the L-shaped clamping plate 5012, the outermost clamping blocks 5034 just push the goods into the storage compartment, completing the storage of the goods; S6. After the goods are stored, the carrying plate 5013 is reset under the action of the first springs 5015, and the second electric push rod 5021 drives the moving plate 5022 to move in the opposite direction, and the moving plate 5022 is pulled out of the storage compartment; S7, when picking up goods, the storage and retrieval mechanism 5 is moved to the picking position under the cooperation of the motor 303, the electric slide plate 401 and the electric slider 402, so that the carrying plate 5013 is lower than the position of the storage compartment partition, and then the first electric push rod 403 is started to push the carrying frame 5011 to move a short distance in the direction of the storage cabinet 1, which is smaller than the distance of the front end gap of the carrying frame 5011, and then the second electric push rod 5021 is started to drive the moving plate 5022 to move, so that the moving plate 5022 completely enters under the partition, and the outer clamping block 5034 just clings to the outer side of the goods; S8. Start the motor 303 to drive the supporting frame 5011 to move upward a short distance. At this time, the partition will press down the front end of the two supporting plates 5013, thereby driving the outer wedge block 5033 to move downward, and then driving the clamping block 5034 on the inner wedge block 5033 to extend out from above the partition through the movable groove 101. Finally, start the second electric push rod 5021 again to drive the movable plate 5022 to reset. At this time, the goods above the partition are pulled onto the two supporting plates 5013 under the action of the two clamping blocks 5034 and the second electric push rod 5021, and then start the first electric push rod 403 to pull the supporting frame 5011 out of the storage cabinet 1, and transport the goods to the lower end of the storage cabinet 1 through the motor 303 to facilitate the removal of the goods.

[0037] To sum up: in this automated three-dimensional storage device and method, the cooperation between the frame structure 501 and the clamping structure 503 enables the goods to be clamped and fixed by the two L-shaped clamps 5012 and the two clamping blocks 5034 under the action of their own gravity, thereby enhancing the stability of goods storage and retrieval, and effectively avoiding the situation where goods fall during storage and retrieval, thereby preventing damage to the goods and danger to the staff; through the arrangement of the first T-slot 4012, the first electric push rod 403 and the T-block 504, it is convenient for the first electric push rod 403 to drive the bearing frame 5011 to extend toward the storage cabinet 1, and then under the action of the motor 303, the partition on the storage cabinet 1 squeezes the bearing plate 5013, completing the upward movement of the inner wedge block 5033, which is conducive to the removal of goods.
