[0024] Embodiment 1:

[0025] Referring to Figure 1 and Figure 2 and in combination with Figure 3 , a storage device includes a storage component 1, a picking component 2 and a frame 3; both the storage component 1 and the picking component 2 are installed on the frame 3; the storage component 1 is arranged above the picking component 2;

[0026] The storage component 1 includes four first clamping members 11, four second clamping members 12, four clamping member driving mechanisms 13 and four fixing rods 14; the first clamping members 11 and the second clamping members 12 are arranged in pairs; the first clamping member 11 includes a first stop bar 111 and a plurality of first transmission rods 112; the second clamping member 12 includes a second stop bar 121 and a plurality of second transmission rods 122; the fixing rod 14 is fixedly connected to the frame 3; the first transmission rod 112 is pivotally connected to the fixing rod 14; the first transmission rod 112 extends downward from the fixing rod 14; the first stop bar 111 is fixedly connected to the lower end of the first transmission rod 112; the output shaft 131 of the clamping member driving mechanism 13 is fixedly connected to the first transmission rod 112; the second transmission rod 122 is pivotally connected to the fixing rod 14; the second transmission rod 122 extends downward from the fixing rod 14; the second stop bar 121 is fixedly connected to the lower end of the second transmission rod 122; the clamping member driving mechanism 13 is fixedly connected to the second transmission rod 122;

[0027] The picking component 2 includes a lifting mechanism 21 and a horizontal conveying mechanism 22; the lifting mechanism 21 includes four first lifting platforms 211, a pallet 212 and a second lifting platform 213; the pallet 212 is arranged at the top of each first lifting platform 211; the maximum diameter of the pallet 212 < the shortest distance between the first stop bar 111 and the second stop bar 121; the horizontal conveying mechanism 22 includes a conveyor belt 221 and a sliding plate 222; the sliding plate 222 is fixedly connected to the conveyor belt 221; the second lifting platform 213 is installed on the sliding plate 222; the first lifting platform 211 is arranged on the second lifting platform 213;

[0028] The first lifting platforms 211 are arranged side by side on the second lifting platform 213; the arrangement direction of the storage component 1 is perpendicular to the arrangement direction of the first lifting platforms 211.

[0029] The working process of the storage device is as follows:

[0030] The process of the cover plate entering the warehouse:

[0031] The cover plate described in the embodiment is a structure similar to a hat, protruding upward inside the inner edge. For cover plates of different diameters, the inner edge diameters are the same. Cover plates with different diameters can be transported mixedly, and this transport device can also be used to transport or store components with a structure similar to that of the cover plate.

[0032] In the initial position of the picking component 2, the cover plate is placed on the pallet 212 manually or mechanically, and the pallet 212 supports in the space protruding upward inside the inner edge of the cover plate; the conveyor belt 221 is driven by a servo motor to drive the sliding plate 222 to the lower part of one group of the first clamping member 11 and the second clamping member 12. The arrangement direction of the cover plate is the same as the extending direction of the first stop bar 111 and the second stop bar 121; the second lifting platform 213 is a lifting cylinder, which pushes a group of the first lifting platforms 211 to rise until the protruding part of the cover plate on the pallet 212 is between the first stop bar 111 and the second stop bar 121; the clamping member driving mechanism 13 is a cylinder. When its output shaft 131 extends, there are relatively balanced thrusts on both the output shaft 131 and the fixed end of the second rotating rod 122, respectively pushing the first transmission rod 112 and the second transmission rod 122 to rotate upward, driving the first clamping member 11 and the second clamping member 12 to open; the first lifting platform 211 pushes the cover plate upward above the first stop bar 111 and the second stop bar 121, and then the output shaft 131 of the clamping member driving mechanism 13 retracts, driving the first transmission rod 112 and the second transmission rod 122 to rotate downward, and the first clamping member 11 and the second clamping member 12 clamp towards the cover plate, so that the first stop bar 111 and the second stop bar 121 support under the cover plate; the first lifting platform 211 retracts downward, the second lifting platform 213 retracts downward, and the conveyor belt 221 drives the lifting mechanism 21 back to the initial position.

[0033] Repeat the warehousing steps. If there are cover plates stored in the first clamping member 11 and the second clamping member 12 during the warehousing process, the second lifting table 213 pushes a group of the first lifting tables 211 to rise until the protruding part of the cover plate on the pallet 212 passes through between the first stop bar 111 and the second stop bar 121. The inner edge of the cover plate overlaps with the cover plates in the first clamping member 11 and the second clamping member 12. When the first clamping member 11 and the second clamping member 12 are opened, the first lifting table 211 supports all the overlapping cover plates to rise. The first clamping member 11 and the second clamping member 12 clamp, and the first stop bar 111 and the second stop bar 121 support under the lowermost cover plate. In this way, multiple cover plates can be stacked and warehoused in batches.

[0034] Regarding whether the number of cover plates in a column is full, the connection counter can be used to count and record the warehousing quantity. The data is transmitted to the controller for statistics. The controller can also control the working mode of the picking component 2 in the storage device according to whether there are cover plates stored in the first clamping member 11 and the second clamping member 12. This process is a conventional technology.

[0035] Wherein the maximum diameter of the pallet 212 < the shortest distance between the first stop bar 111 and the second stop bar 121. More specifically, the shortest distance between the first stop bar 111 and the second stop bar 121 should be greater than or equal to the inner edge diameter of the cover plate and less than the diameter of the smallest cover plate. The maximum width that the first clamping member 11 and the second clamping member 12 can clamp (i.e., the sum of the width of the first stop bar 111, the width of the second stop bar 121, and the minimum distance between the first stop bar 111 and the second stop bar 121) should be greater than or equal to the diameter of the largest cover plate. With such settings, the first stop bar 111 and the second stop bar 121 have a certain width and can carry cover plates of different sizes within a certain diameter range, realizing the mixed storage of cover plates of different sizes. For the specific settings of dimensions, distances, etc., they can be adjusted according to the actual situation, which is a conventional means.

[0036] Setting multiple first transmission rods 112 and multiple second transmission rods 122 can better balance the first stop bar 111 and the second stop bar 121, making them more stable when opening and clamping. The first stop bar 111 and the second stop bar 121 can extend in length according to the warehousing quantity of the cover plates in the same batch, which also expands the storage quantity of cover plates in the storage device.

[0037] Cover plate out-of-warehouse process:

[0038] The pallet 212 does not place any objects. The lifting mechanism 21 is driven by the conveyor belt 221 from the initial position to a group of first clamping members 11 and second clamping members 12 with a cover plate placed above. The second lifting platform 213 pushes a group of the first lifting platforms 211 to rise, and the first lifting platforms 211 also rise, so that the pallet 212 moves upward through between the first stop bar 111 and the second stop bar 121 and presses against the bottom end of the cover plate. The first clamping member 11 and the second clamping member 12 open, then the first lifting platform 211 retracts downward, and the first clamping member 11 and the second clamping member 12 clamp and close. The second lifting platform 213 retracts downward, the lifting mechanism 21 returns to the initial position, and then the cover plate on the pallet 212 is taken away manually or mechanically.

[0039] If there are multiple cover plates stored in the first clamping member 11 and the second clamping member 12 during the outbound process, the pallet 212 first presses against the bottom end of the lowermost cover plate. When the first clamping member 11 and the second clamping member 12 open, the pallet 212 supports all the cover plates. The first lifting platform 211 descends to the position where the lowermost cover plate is below the first stop bar 111 and the second stop bar 121. The first clamping member 11 and the second clamping member 12 clamp, and the first stop bar 111 and the second stop bar 121 support the second cover plate below, so that the lifting mechanism 21 can take away one cover plate from the warehouse.

[0040] The storage device can be connected to the controller. The controller can control the working mode of the picking component 2 in the storage device according to whether there is a single cover plate or multiple cover plates stored in the first clamping member 11 and the second clamping member 12. This process is a conventional technology.

[0041] Embodiment 2:

[0042] The structural feature of this embodiment is that a sensor (not shown in the figure) is provided on the pallet 212; the rest of the structure and features are the same as those in Embodiment 1. The working process of this embodiment is as follows:

[0043] Warehousing:

[0044] When the lifting mechanism 21 is in the initial position, cover plates can be placed at some positions and not at other positions on a set of supporting plates 212. The lifting mechanism 21 moves below one set of the first clamping member 11 and the second clamping member 12. First, the second lifting platform 213 rises, and the sensor senses whether there is a cover plate on the supporting plate 212. The first lifting platform 211 without a cover plate rises first until it presses against the bottom end of the cover plate within the first clamping member 11 and the second clamping member 12. Then, the first clamping member 11 and the second clamping member 12 open, and the first lifting platform 211 with a cover plate rises until all the stacked cover plates are lifted above the first stop bar 111 and the second stop bar 121. The first clamping member 11 and the second clamping member 12 clamp, and the storage is completed. Through the sensing of the sensor, the cover plates at different positions in the library can be supplemented and stored targeted. As for the selection of the storage position, the suitable empty space for storage can be found through the data recording and statistics in the controller.
