[0058] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0059] See Figure 1 As shown, an embodiment of the first aspect of this application discloses a stacker, which installs a first slide rail on the shelf of a storage cabinet, and then slides the mounting frame to the first slide rail via a first slider 110, and drives the mounting frame to slide along the first slide rail via a first drive mechanism 200. Thus, the stacking device 300 disposed on the mounting frame can slide along the first slide rail, thereby causing the stacking device 300 to move along the first slide rail.

[0060] Compared to conventional methods of moving stacker cranes using ground and overhead rails, the embodiments of this application install a first slide rail on the storage cabinet shelf and slide the stacking device 300 onto the first slide rail using a first slider 110. During the installation of the stacking device 300, there is no need to adjust the relative position between the stacking device 300 and the storage cabinet, which can reduce the installation difficulty of the stacker crane. At the same time, since the stacker crane is installed on the storage cabinet shelf via the first slide rail and the first slider 110, the stacker crane and the storage cabinet can be moved as a whole when the storage cabinet is moved, which improves the convenience of moving the storage cabinet.

[0061] The following will combine Figures 1 to 9 The stacker crane disclosed in the first aspect of this application will be specifically explained and described.

[0062] like Figures 1 to 9 As shown, an embodiment of the first aspect of this application provides a stacker crane, including an installation structure, a first drive mechanism 200, and a stacking device 300.

[0063] Specifically, the mounting structure includes a first slide rail, a first slider 110, and a mounting bracket. The first slide rail is used to connect to the shelf of the storage cabinet, and the first slider 110 is fixedly mounted on the mounting bracket, with the first slider 110 slidably connected to the first slide rail. In this embodiment, the first slide rail is horizontally arranged, and the mounting bracket is slidably connected to the first slide rail via the first slider 110. The first slide rail not only provides guidance for the first slider 110 but also supports both the first slider 110 and the mounting bracket.

[0064] The first drive mechanism 200 is mounted on the mounting bracket and is used to drive the mounting bracket to slide along the first slide rail.

[0065] The stacking device 300 is mounted on the mounting frame and is used to transfer workpieces and to perform workpiece storage and retrieval operations.

[0066] In this embodiment, the workpiece is a single-phase meter, a three-phase meter, etc.

[0067] Of course, in other embodiments, the workpiece may also be other products suitable for stacker crane transfer, which is not limited here.

[0068] In one embodiment, see Figure 1 The mounting frame includes a first connecting seat 121, a second connecting seat 122, and a column 123; the first connecting seat 121 and the second connecting seat 122 are spaced apart in a vertical direction; both ends of the column 123 are connected to the first connecting seat 121 and the second connecting seat 122; the stacking device 300 is movably installed between the first connecting seat 121 and the second connecting seat 122. The column 123 is vertically positioned.

[0069] In one embodiment, see Figure 1 The first drive mechanism 200 includes a rack (not shown in the figure), a drive gear 210, and a rotation drive structure. Specifically, the rack is mounted on the shelf and is arranged parallel to the first slide rail; the rotation drive structure is mounted on the first connecting seat 121, and the output end of the rotation drive structure is connected to the drive gear 210, which meshes with the rack. The rack extends parallel to the first slide rail.

[0070] When the rotation drive structure is activated, it can drive the drive gear 210 to rotate. The meshing rack converts the rotational motion of the drive gear 210 into linear motion along the extension direction of the rack, thereby driving the entire mounting bracket to move smoothly along the first slide rail.

[0071] In this embodiment, please refer to Figure 1 and Figure 2 The rotation drive structure includes a mounting plate 220, a drive motor 230, and a reducer 240. The mounting plate 220 is fixedly connected to the column 123. The reducer 240 is connected to the output end of the drive motor 230, and the reducer 240 and the drive motor 230 are integrally mounted on the mounting plate 220. The output end of the reducer 240 is fixedly connected to the drive gear 210. The drive motor 230 drives the drive gear 210 to rotate, causing the drive gear 210 to move relative to the rack, thereby causing the entire mounting frame to move along the first slide rail.

[0072] In one embodiment, see Figure 1 The stacking device 300 includes forks 310 and a lifting mechanism 320. The forks 310 are movably mounted on the column 123, and the lifting mechanism 320 is used to drive the forks 310 to rise and fall.

[0073] When a workpiece needs to be moved to a storage compartment at a specified height, the lifting mechanism 320 can drive the forks 310 to rise and fall along the column 123 until the forks 310 reach the corresponding height. Then, the forks 310 can extend to complete the workpiece loading and unloading operation. With the horizontal movement of the mounting frame along the first slide rail, the workpiece can be transferred to different positions in the storage cabinet.

[0074] In one embodiment, see Figure 5 and Figure 6 The forklift 310 includes a connecting frame 311, a flat plate 312, and a telescopic drive mechanism 313. Specifically, the connecting frame 311 is movably connected to the column 123; the flat plate 312 is mounted on the connecting frame 311 via the telescopic drive mechanism 313; the telescopic drive mechanism 313 is used to drive the flat plate 312 to move. The direction of displacement of the flat plate 312 is perpendicular to both the column 123 and the first slide rail.

[0075] When it is necessary to store or retrieve a workpiece, the telescopic drive mechanism 313 drives the flat plate 312 to extend towards the drawer of the storage cabinet, receive or send out the workpiece, and then retract to complete the transfer of the workpiece.

[0076] In one embodiment, see Figure 1 , Figure 5 and Figure 6 The telescopic drive mechanism 313 includes a lead screw 3131, a lead screw nut, a rotation drive component 3132, and a transmission structure. Specifically, the lead screw nut cooperates with the lead screw 3131 and is fixedly connected to the plate 312; the rotation drive component 3132 drives the lead screw 3131 to rotate through the transmission structure, thereby causing the plate 312 to move. The axial direction of the lead screw 3131 is perpendicular to the first slide rail space.

[0077] When the drive unit 3132 outputs torque, it will drive the lead screw 3131 to rotate through the transmission structure. The rotation of the lead screw 3131 will drive the lead screw nut to move linearly along the axis of the lead screw 3131, thereby driving the plate 312 to move back and forth in a direction perpendicular to the first slide rail.

[0078] In this embodiment, the transmission structure includes a first transmission wheel 31331, a second transmission wheel 31332, and a transmission belt 31333. The first transmission wheel 31331 is mounted on the output end of the rotation drive component 3132, the second transmission wheel 31332 is mounted on one end of the lead screw 3131, and the transmission belt 31333 connects the first transmission wheel 31331 and the second transmission wheel 31332. Thus, by driving the first transmission wheel 31331 to rotate, the lead screw 3131 can be driven to rotate, thereby driving the plate 312 to move.

[0079] Furthermore, the rotation drive component 3132 is specifically a servo motor, the first transmission wheel 31331 and the second transmission wheel 31332 are both synchronous pulleys, and the transmission belt 31333 is specifically a synchronous belt.

[0080] In one embodiment, see Figure 1 , Figure 7 and Figure 8 The lifting mechanism 320 includes a lifting drive structure 321, a first synchronous pulley 322, a second synchronous pulley 323, a synchronous belt 324, and a connecting structure 325. Specifically, the lifting drive structure 321 is mounted on the second connecting seat 122; the first synchronous pulley 322 is mounted on the first connecting seat 121; the second synchronous pulley 323 is mounted on the second connecting seat 122; the synchronous belt 324 is connected to the first synchronous pulley 322 and the second synchronous pulley 323 respectively; the connecting structure 325 is fixed on the synchronous belt 324 and is connected to the connecting frame 311.

[0081] When the lifting drive structure 321 drives the second synchronous pulley 323 to rotate, the synchronous belt 324 will circulate around the first synchronous pulley 322 and the second synchronous pulley 323, thereby driving the connecting structure 325 fixed on the synchronous belt 324 to move synchronously. In this way, the connecting structure 325 can drive the connecting frame 311, that is, drive the entire fork 310 to lift and lower along the column 123 to meet the needs of picking up and putting down goods in drawers of different heights.

[0082] In one embodiment, see Figure 1 The stacking device 300 also includes a clamping mechanism 330. The clamping mechanism 330 has a clamping part 331 formed above the fork 310. When the fork 310 receives the workpiece, the clamping part 331 can clamp and fix the workpiece on the fork 310, so as to prevent the workpiece from slipping or shifting during the transfer process and improve the safety and stability of the transfer operation.

[0083] In one embodiment, see Figure 1 and Figure 2 The stacker crane also includes a second slide rail 341 and a second slider 342. The second slide rail 341 is fixed vertically to the column 123, and the second slider 342 is fixed to the connecting frame 311. The second slider 342 is slidably connected to the second slide rail 341. This allows the forks 310 to move up and down along the column 123 more smoothly and stably, reducing swaying and further improving the accuracy of picking up and placing goods.

[0084] In this embodiment, see Figure 2The connecting bracket 311 of the fork 310 is fixedly connected to the second slider 342 via a connecting plate 343. The opening of the groove in the second slider 342 that mates with the second slide rail 341 faces the same direction as the movement of the plate 312 when it retracts. Thus, the second slide rail 341 not only provides guidance for the second slider 342 but also provides support, reducing the risk of the second slider 342 and second slide rail 341 locking up due to force after the fork 310 lifts the workpiece, and improving the smoothness of the fork 310's lifting and lowering.

[0085] In one embodiment, see Figure 1 The stacker crane also includes a first limiting structure 410, which is installed on the first connecting seat 121. The first limiting structure 410 is located below the stacking device 300 and is used to abut against the stacking device 300. Because the first limiting structure 410 is located below the stacking device 300, it can abut against the stacking device 300 when the forks 310 are lowered to their lowest position, thus achieving a lower limit and preventing the forks 310 from descending excessively.

[0086] In one embodiment, see Figure 1 The stacker crane also includes a second limiting structure 420, which is installed on the second connecting seat 122 and located above the stacking device 300. The second connecting seat 122 is used to abut against the stacking device 300. The second limiting structure 420, installed on the second connecting seat 122 and located above the stacking device 300, can abut against the stacking device 300 when the forks 310 are raised to their highest position, achieving an upper limit stop, preventing the forks 310 from rising excessively and causing collision accidents, and improving the safety of equipment operation.

[0087] In one possible application scenario, the stacker crane is installed on an intelligent high-density storage cabinet. When a table needs to be stored, the intelligent electric conveyor drawer of the storage cabinet will transport the table into the cabinet. The stacker crane's lifting mechanism 320 drives the forks 310 to move up and down to the pick-up / placement height of the intelligent electric conveyor drawer. The rotating drive component 3132 drives the lead screw to rotate through the transmission structure, so that the flat plate 312 extends into the intelligent electric conveyor drawer. Then, the forks 310 are raised to lift the table and retrieve it. Next, the drive motor 230 drives the drive gear 210 to rotate. Under the action of the first slider 110, the stacker crane moves horizontally left and right within the intelligent high-density storage cabinet to the position of the intelligent electric conveyor drawer. The rotating drive component 3132 drives the lead screw to rotate in the opposite direction, retracting the flat plate 312. Then, the lifting mechanism 320 drives the forks 310 to move up and down to the pick-up / placement height of the shelf storage position in the intelligent high-density storage cabinet. The flat plate 312 is then extended, and the forks 310 are lowered to place the table into the shelf storage position, completing the table storage process.

[0088] In one possible application scenario, the stacker crane is installed on an intelligent high-density storage cabinet. When a meter needs to be retrieved, the lifting mechanism 320 of the intelligent stacker crane moves the forks 310 up and down to the retrieval height of the rack storage position. The flat plate 312 of the forks 310 extends to the rack storage position, and then drives the forks 310 to be raised as a whole, so that the meter falls on the flat plate 312. After the flat plate 312 picks up the meter, under the action of the first driving mechanism 200, the stacker crane moves horizontally left and right inside the intelligent high-density storage cabinet to the position of the intelligent storage electric conveyor drawer. Then, the flat plate 312 of the forks 310 extends into the intelligent storage electric conveyor drawer, and then controls the forks 310 to be lowered as a whole, placing the meter into the intelligent storage electric conveyor drawer. The intelligent storage electric conveyor drawer will then transport the meter to the outside of the intelligent high-density storage cabinet, completing the meter retrieval process.
