The plate stacking area 1 is provided with a stacking trolley 11, which is used to place the plates to be assembled, and the stacking trolley 11 transports the plates placed on the stacking trolley 11 to the plate sorting area 2 through an AGV 12.

[0014] At the same time, the plate dividing area 2 is provided with a dividing and transplanting machine 21, which is used to clamp and limit the plate transported and placed on the stacking trolley 11. In addition, the plate dividing area 2 is also provided with a dividing gripper 22, which is movably installed and connected to the dividing and transplanting machine 21, and a visual system (existing 3D visual recognition control system) is also installed on the dividing gripper 22; the plate on the stacking trolley 11 is identified and positioned by controlling the visual system, and then the plate placed on the stacking trolley 11 is grasped and limited by controlling the dividing gripper 22.

[0015] The heat-tightening assembly area 3 is provided with a truss gripper 31, which is used to grab the electrode plate clamped and limited on the material-splitting gripper 22 of the material-splitting transplanter 21, and transport the electrode plate to the heat-tightening workbench 32 provided in the heat-tightening assembly area 3 for assembly processing. The truss gripper 31 is movably installed and connected to the truss system 33 (the existing truss guide rail control system), and the truss gripper 31 is also installed and connected to a visual system (the existing 3D visual recognition control system). A positioning hoist 34 can also be movably installed on the truss system 33. The positioning hoist 34 is set between the truss gripper 31 and the material distribution gripper 22. The positioning hoist 34 is used to lift the electrode plate that is moved and grabbed by the material distribution gripper 22 and placed on the positioning hoist 34 to a suitable height, and then positioned and identified by the visual system on the truss gripper 31, and the electrode plate of the positioning hoist 34 is grabbed and moved to the electrolytic cell on the assembly cart provided in the heat-tightening assembly area 3 by the truss gripper 31 for installation and assembly. In order to facilitate the heat-tightening and assembly operations, a manual lifting platform 36 that can be lifted and lowered is set above the heat-tightening workbench 32. The manual lifting platform 36 is used by operators to perform heat-tightening and assembly operations such as heat-tightening and assembly of the electrolytic cell and the electrode plate on the heat-tightening workbench 32 through heat-tightening equipment (or various assembly equipment for assembling the electrode plate and the electrolytic cell).

[0016] The test area 4 is equipped with a ground hoisting system 41, which is used to transport the electrolytic cell plates assembled on the heat-tightening workbench 32 and after heat-tightening to the finished product area 5 for temporary storage, waiting for shipment. The ground hoisting system 41 is movably installed with a flipping system for flipping and moving the electrolytic cell after heat-tightening (assembly) work on the heat-tightening workbench 32, and the electrolytic cell after heat-tightening work is moved and transported to the finished product area 5 for temporary storage through the flipping system.

[0017] Example 2 Furthermore, in the embodiment, the plate stacking area 1 is provided with a plurality of stacking carts 11, which are evenly distributed in the plate stacking area 1 according to the design, and each stacking cart 11 moves and transports the plates placed in the stacking cart 11 through the AGV 12 (the existing intelligent control cart system). After the stacking cart 11 is moved to the designated position, the material dividing gripper 22 on the material dividing and transplanting machine 21 is controlled to grab the plates placed in the stacking cart 11 and move them to the heat tightening and assembly area 3 for heat tightening and assembly.

[0018] In the embodiment, the material dividing gripper 22 on the material dividing and transplanting machine 21 is installed and connected to one end of the movable telescopic column, and the material dividing gripper 22 is connected to the movable telescopic column through an electric rotating table. The electric rotating table can be used to control the rotation of the material dividing gripper 22, so as to facilitate the grabbing and moving of the pole plates placed in the stacking trolley 11. At the same time, a sliding guide rail that can be raised and lowered and slid is provided at the top of the movable telescopic column, and the movable telescopic column can be raised and lowered and connected to the first movable frame through the sliding guide rail; the first movable frame is adjustable with the second movable frame. The specific implementation method is as follows: the top end of the first movable frame close to one end of the second movable frame is movably hingedly connected to the top end of the second movable frame through a hydraulic cylinder, and the bottom end of the first movable frame close to one end of the second movable frame is also movably hingedly connected to the bottom end of the second movable frame through a hydraulic cylinder. By controlling the hydraulic cylinder at the top of the first movable frame and the hydraulic cylinder at the bottom of the first movable frame, "free swinging" can be achieved. At the same time, the end of the second movable frame away from the first movable frame is provided with a hydraulic telescopic column that can be horizontally extended and retracted, and the end of the hydraulic telescopic column close to the second movable frame is connected to a connecting seat, and the top end of the second movable frame close to the connecting seat is hingedly connected to a hydraulic rod, and the other end of the hydraulic rod is hinged on the sliding guide rail of the seat, and the hydraulic rod is horizontally hinged and slid with the connecting seat through the sliding guide rail; similarly, the bottom end of the second movable frame close to the connecting seat is also hingedly connected to a hydraulic rod, and the other end of the hydraulic rod is hinged on the sliding guide rail of the seat, and the hydraulic rod is horizontally hinged and slid with the connecting seat through the sliding guide rail; such a design can control the horizontal movement of the second movable frame by controlling the sliding guide rail, and then by controlling the extension and retraction of the hydraulic rod on the sliding guide rail, the second movable frame can be driven to "freely move". In addition, the end of the hydraulic telescopic column away from the connecting seat is connected to the material dividing and transplanting machine 21 through a telescopic hydraulic rod. With such a design, it is finally possible to drive the material dividing gripper 22 to achieve "free movement" and grab and move the pole plates placed in the stacking trolley 11.

[0019] Example 3 When heat tightening and assembly are required in the heat tightening assembly area 3, the truss gripper 31 is controlled to grab the pole plate clamped and limited on the dividing gripper 22 of the dividing and transplanting machine 21, and the pole plate is transported and moved to the heat tightening workbench 32 set in the heat tightening assembly area 3 for assembly processing.

[0020] In the embodiment, the truss system 33 is controlled to control the truss gripper 31 installed on the truss system 33 to move to a suitable position, and then the electrode plate on the positioning elevator 34 is identified and positioned by the visual system installed on the truss gripper 31, and then the electrode plate placed on the positioning elevator 34 is grabbed by controlling the truss gripper 31 and moved to the heat tightening workbench 32, so as to facilitate heat tightening, assembly and other operations on the heat tightening workbench 32.

[0021] The heat-tightening workbench 32 is used to be installed and fixed at a position specified by the heat-tightening assembly area 3; the top surface of the heat-tightening workbench 32 is provided with a movable clamping mechanism for clamping and limiting the electrode plate and the electrolytic cell. It should be noted here that the movable clamping mechanism includes a plurality of clamping bases, which can be horizontally slidably arranged on the top surface of the heat-tightening workbench 32 through an electric guide rail; at the same time, a rotating cylinder is arranged on the clamping base, and the shell of the rotating cylinder is used to be fixed to the clamping base by bolts, and the output end of the rotating cylinder is connected to a finger cylinder, and a clamping claw for clamping and limiting the electrode plate and the electrolytic cell is movably installed on the finger cylinder; in this way, when the truss gripper 31 grabs and moves the electrode plate and places it between the clamping claws of the finger cylinder on the heat-tightening workbench 32, the electrode plate between the clamping claws is clamped and fixed by controlling the movement of the clamping claws on the clamping base, and then the electrode slot clamped and limited on the clamping base and the electrode plate clamped and limited on the clamping base are moved to appropriate positions respectively, so that the operator can perform heat-tightening, assembly and other operations on the matching electrode slot and the electrode plate.

[0022] At the same time, an artificial lifting platform 36 is provided at a suitable position above the heat-tightening workbench 32. The operator stands on the artificial lifting platform 36 and performs heat-tightening, assembly and other operations by setting the electrolytic cell and the plate installed on the artificial lifting platform 36. It should be noted here that the artificial lifting platform 36 can be installed on a lifting movable bracket in a lifting and translational manner. The specific implementation can be: the two sides of the artificial lifting platform 36 can be lifted and movably arranged through vertically arranged electric lifting guide rails and vertical guide beams respectively arranged on both sides of the lifting movable bracket, and the bottom ends of the two vertical guide beams are used to be connected and fixed to the ground of the heat-tightening assembly area 3, so as to stabilize and reinforce the entire lifting movable bracket. At the same time, a horizontal movable bracket is connected to the artificial lifting platform 36, and the horizontal movable bracket can be horizontally moved with the artificial lifting platform 36 through a horizontally arranged electric horizontal guide rail (an electric horizontal guide rail system composed of an electric horizontal guide rail that can realize horizontal movement left and right and an electric horizontal guide rail that can realize horizontal movement front and back) and a guardrail is installed around the horizontal movable bracket to protect the operator; the required heat tightening equipment (or various assembly equipment for assembling the electrode plate and the electrolytic cell) is installed on the horizontal movable bracket by electrical connection; such a design can be realized by synchronously controlling the two An electric lifting guide rail drives the manual lifting platform 36 to move up and down; at this time, the operator stands on the horizontal movable bracket on the manual lifting platform 36, moves the horizontal movable bracket on the manual lifting platform 36 to a suitable height position, and then controls the "operation control position" of the horizontal movable bracket in real time through the electric lifting guide rail and the electric horizontal guide rail according to the position of the electrolytic cell and the plate to be heat-tightened and assembled as needed, so that the operator can pair the plate and the electrolytic cell of the heat-tightening workbench 32 through the control equipment installed on the horizontal movable bracket, and then perform processing operations such as heat-tightening and assembly.

[0023] Example 4 After the heat-tightening and assembling operations are performed in the heat-tightening and assembling area 3, the components are moved to designated locations in the testing area 4 by controlling the ground hoisting system 41 for temporary storage in order to wait for shipment.

[0024] In this embodiment, a flipping system for flipping and moving the electrolytic cell after the hot-tightening (assembly) work on the hot-tightening workbench 32 is movably installed on the ground hoisting system 41 (also an existing guide rail control system), and the electrolytic cell after the hot-tightening work is moved and transported to the finished product area 5 for temporary storage through the flipping system. The set flipping system includes a flipping movable frame, which is horizontally movably installed on the ground hoisting system 41 through an electric guide rail, so that the horizontal position movement of the flipping movable frame can be controlled. The flipping movable frame is provided with a flipping control cylinder at one end close to the heat-tightening workbench 32, and the flipping control cylinder is rotatably connected to the flipping movable frame at one end through a rotating electric table, and the rotating electric table is rotatably connected to the flipping movable frame at one end close to the flipping movable frame through a rotatable rotating shaft, and the rotating shaft is connected to the output end of the servo motor, and the servo motor is used to be installed and connected to the flipping movable frame, and the rotating shaft is driven by the servo motor to rotate, thereby driving the rotating electric table to "rotate", and then the rotating electric table is rotationally controlled, and the two cooperate with each other to drive the flipping control cylinder to "freely move"; and a flipping clamping cylinder is connected to the output end of the flipping control cylinder, and a flipping clamping finger cylinder is installed and connected to the flipping clamping cylinder, and the flipping clamping finger cylinder is driven by the flipping clamping cylinder to grab the electrolytic cell after the heat-tightening (assembly) work on the heat-tightening workbench 32, move it to the designated position of the test area 4, and temporarily store it in sequence, waiting for delivery.
