The two ends of the lifting beam 4-2 are connected to the left lifting column 4-15 and the right lifting column 4-6 respectively. The left lifting column 4-15 and the right lifting column 4-6 form a sliding connection with the left platform column 4-17 and the right platform column 4-7 through the linear guide rails 4-16. The left end of the lifting beam 4-2 is connected to the left electric push rod 4-14 through the left lifting column 4-15, and the right end is connected to the right electric push rod 4-8 through the right lifting column 4-6; the lifting beam 4-2 moves up and down under the action of the left electric push rod 4-14 and the right electric push rod 4-8.

[0067] A plurality of transition storage racks 4-4 and exchange assistants 4-3 are installed along the length of the lifting longitudinal beam 4-2. The left exchange platform 4-1 and the right exchange platform 4-5 are provided with rectangular holes corresponding to the transition storage racks 4-4 and the exchange assistants 4-3. When the lifting longitudinal beam 4-2 rises, the transition storage racks 4-4 and the handover assistants 4-3 pass through the rectangular holes and stand on the left exchange platform 4-1 and the right exchange platform 4-5 to complete the handover task of the copper busbars.

[0068] Specifically, Fig.12 As shown, the exchange assistant 4-3 includes an auxiliary head 4-3-1 and a connecting rod arm 4-3-3.

The push block 5-5 on the outbound conveying chain of the inbound and outbound conveying device is at the innermost end close to the left exchange platform 4-1 and the right exchange platform 4-5, and the push block 5-5 on the inbound conveying chain is at the outermost end away from the left exchange platform 4-1 and the right exchange platform 4-5.

[0081] 2. The operation sequence of copper discharge warehouse:

[0082] Step 1: Send instructions

[0083] Assume that, according to the production and processing needs, an instruction is issued to take a copper bar of a certain specification, and the computer automatically retrieves and confirms the coordinate position of this copper bar, that is, the current storage position on the x-layer of the material warehouse and the y-row in the material tray.

[0084] Step 2: The pick-up elevator is driven by the lifting motor 3-15 and quickly rises to above the xth floor according to the guidance stroke of the laser rangefinder 3-7;

[0085] Step three: The left and right motors of the x-th layer (left propulsion motor 1-34 and right propulsion motor 1-35) drive the ball screws 2-7 at both ends of the storage tray of this layer to rotate, and under the guidance of the laser or encoder, the storage tray of this layer is gradually pushed out of the material warehouse laterally, and the longitudinal center line position of the y-th row of the storage tray is moved to coincide with the longitudinal center line of multiple copper bar pickers 3-10 of the picking elevator waiting above for positioning.

[0086] Step 4: The picking elevator is driven by the lifting motor 3-15 and guided by the laser rangefinder 3-7 and the laser stopper 3-8 until the copper bar picker 3-10 automatically clamps the copper bar to be picked up on the yth row of the xth layer storage tray.

[0087] Step 5: The pick-up elevator rises slightly and completely separates from the storage tray.

[0088] Step 6: Driven by the motors at both ends and guided by the lateral laser ranging or encoder, the x-layer storage tray returns to its original position in the material storage according to the setting requirements.

[0089] Step 7: The picking elevator carries the obtained copper bar down according to the specified limit stroke under the guidance of the laser rangefinder 3-7 and the height laser limiter 3-8, so that the front edge collision block at the lower end of the copper bar picker 3-10 slightly collides with the table surface of the left exchange platform 4-1 and the right exchange platform 4-5, so as to open the block of the copper bar picker 3-10 and leave the copper bar on the transition storage rack 4-4 of the left exchange platform 4-1 and the right exchange platform 4-5.

[0090] Step 8: Pick up the lift and return to the initial position to wait.

[0091] Step 9: At the same time as step 8, the lifting beam 4-2 under the left exchange platform 4-1 and the right exchange platform 4-5 carries the transition storage rack 4-4 downward under the drive of the left electric push rod 4-14 and the right electric push rod 4-8. As the transition storage rack 4-4 sinks through the left exchange platform 4-1 and the right exchange platform 4-5, the copper bar taken is directly placed upright on the table of the left exchange platform 4-1 and the right exchange platform 4-5. As the lifting beam 4-2 under the platform descends, the exchange auxiliary device 4-3 fixedly installed on the left exchange platform 4-1 and the right exchange platform 4-5 rotates counterclockwise by 90° under the pull of its connecting rod, and the copper bar originally erected sideways is placed flat on the platform.

[0092] Step 10: Start the copper bar outbound conveying device to make the conveying sprocket chain run in the outbound direction (counterclockwise). Under the push of the push block 5-5 installed on the outbound transmission chain, the copper bar that has been laid flat on the left exchange platform 4-1 and the right exchange platform 4-5 is pushed to the processing conveyor line to complete the processing and material taking task.

[0093] 3. Process sequence of new parts entering the warehouse (or remaining parts returning the warehouse)

[0094] Step 1: The operator confirms the specifications, quality, surface treatment and other parameters of the copper busbars to be stored (or returned), and inputs them into the computer, which then arranges the storage coordinates.

[0095] Step 2: The operator issues a warehousing instruction;

[0096] Step 3: The lifting longitudinal beam 4-2 under the left exchange platform 4-1 and the right exchange platform 4-5 is driven by the left and right electric telescopic push-pull rods 4-14 and 4-8 to descend, so that the short claws of the transition storage rack 4-4 on the lifting longitudinal beam 4-2 are completely sunk below the table surface of the left exchange platform 4-1 and the right exchange platform 4-5, and at the same time, the long claws of the exchange auxiliary device 4-3 fixed on the left exchange platform 4-1 and the right exchange platform 4-5 are pulled down (counterclockwise) by the connecting rod and rotated below the table surface of the left exchange platform 4-1 and the right exchange platform 4-5;

[0097] Step 4: Start the copper bar storage conveying device, make the conveying sprocket rotate clockwise in the storage direction (from the end of the conveying line), and push the copper bar placed on the conveying line to the left exchange platform 4-1 and the right exchange platform 4-5 under the push of the block 5-5 on the left and right storage transmission chains, and make the front end of the copper bar close to the inner side of the long claw of the copper bar transition storage rack 4-4;

[0098] Step 5: The lifting longitudinal beam 4-2 under the left exchange platform 4-1 and the right exchange platform 4-5 rises driven by the left and right electric push-pull rods, causing the long claws of the exchange auxiliary device 4-3 installed and fixed on the left exchange platform 4-1 and the right exchange platform 4-5 to gradually rise through the reverse (clockwise) rotation of the connecting rod lifting and pushing, and expose the upper plane of the left exchange platform 4-1 and the right exchange platform 4-5. As the long claws of the exchange auxiliary device 4-3 continue to rise, the copper bar begins to be reversed until the copper bar originally placed horizontally is completely erected vertically. At the same time, as the transition storage rack 4-4 gradually rises, the vertical copper bar is lifted, so that the lower end surface of the vertical copper bar is about 15mm higher than the table surface of the fixed exchange platform 4-1, 4-5;

[0099] Step 6: The pick-up elevator descends, and the copper bar picker 3-10 automatically picks up the copper bar. Then, the pick-up elevator rises to above the material tray of the storage layer automatically selected by the computer;

[0100] Step 7: According to the row number position requirements selected by the computer, the material storage tray of this layer automatically moves horizontally out of the material warehouse, and the longitudinal center line of the material tray to be stored in the row position coincides with the longitudinal center line of the copper bar picker 3-10 under the picking elevator;

[0101] Step 8: The picking elevator descends, and the copper row is placed into the storage tray through the collision of the lower front edge collision block of the copper row picker 3-10 under the picking elevator and the lateral support 2-4 of the storage rack;

[0102] Step 9: The pick-up elevator is slightly lifted and separated from the material storage tray at that layer;

[0103] Step 10: The storage tray on this layer automatically moves horizontally back to its original position in the warehouse;

[0104] Step 11: Pick up the lift and lower it to the initial position and wait.
