Description
Technical Field
[0001] The utility model relates to the technical field of hydrometallurgical plate stripping equipment, in particular to an automatic connecting device for pole plates of plate stripping equipment. Background Art
[0002] Wet electrolytic metallurgy is a method of reducing metal ions to pure metals under the action of an electric field by utilizing the conductivity of an electrolyte solution. It is a mainstream process for smelting non-ferrous metals in the world today and is widely used in the smelting of non-ferrous metals such as copper, zinc, chromium, manganese, gold, silver, nickel, and cobalt. During the production process, a metal salt solution containing metal ions is placed in the electrolytic cell, and cathode plates and anode plates are placed in the electrolytic cell alternately at a certain distance. The metal ions are adsorbed on the plates through the electrolysis process. When the metal ion adsorption layer on the plates reaches a certain thickness, a crane is used to remove part of the plates from the electrolytic cell, and the deposited metal on the plates is peeled off, and then melted and cast into metal ingots to obtain the final product.
[0003] At present, various domestic non-ferrous metal smelting enterprises have begun to use automated plate stripping equipment to strip metal from the plates. In the actual production process, when the plate absorbs a certain amount of metal in the electrolyte by electrolysis, it is necessary to lift it to the top of the plate stripping equipment by a crane and place it on the transmission chain of the plate stripping equipment. The plate that has completed the metal sheet stripping and brushing also needs to be lifted off the transmission chain by a crane and returned to the electrolytic cell. In addition, during the production process, due to the influence of production processes, failures and other factors, some of the stripped plates have metal residues, bends, breakages, etc., which need to be manually removed from the production line and then lifted off by the crane; after removal, in order to ensure that the number of plates returning to the tank remains unchanged, the crane is also required to lift qualified plates into the production line and then manually replenish them into the production line. This operation method takes a long time, occupies a large space, has a high demand for the use of the crane, and has low production efficiency. At the same time, when the automated plate stripping equipment is in operation, whenever a plate is lifted in or lifted out by the crane, the entire system must stop working and wait for the crane to complete the lifting operation before continuing production. This way of working wastes a lot of working time and has low production efficiency. Therefore, the process of overhead crane lifting the plate and the process of the plate entering the transmission line of the automatic stripping system must be separated and not interfere with each other, so as to save downtime and waiting time and improve production efficiency.
[0004] Take zinc smelting as an example: Domestic hydrometallurgical zinc smelting usually adopts 1.1m 2 -3.2m 2 The larger the plate area, the longer the total length of the two-span electrolytic cell, and the heavier the cathode plate with metal zinc attached. 2Taking the large-plate zinc electrowinning process as an example, the total length of the two-span electrolytic cells is usually more than 30m, and the mass of a single cathode plate with attached metallic zinc is about 120kg.
[0005] CN212560473U discloses a fast feeding docking system for a double-plate zinc stripping unit, which includes a trolley and a cathode plate transmission chain. The trolley can transport the cathode plate to the cathode plate transmission chain under the guidance of a guide mechanism. The inventors have found that the cathode plate transport device has at least the following problems:
[0006] (1) The docking system uses a trolley to directly dock the cathode plate with the overhead crane, that is, the cathode plate lifted by the overhead crane is directly placed on the trolley, and then the trolley transfers the cathode plate to the cathode plate transmission chain; at the same time, the cathode plate after stripping needs to be transferred to the designated location by the trolley, and then transported away by the overhead crane. This means that when the trolley transfers the cathode plate, the stripping system must stop and wait for the trolley to complete the placement of the cathode plate before continuing the operation, resulting in low continuous operation rate of the stripping system, frequent shutdowns, and low production efficiency.
[0007] (2) The horizontal moving rollers of the trolley are arranged relatively concentratedly. However, in order to ensure the placement of the entire tank of cathode plates, the length of the lifting mechanism is relatively large (usually between 3-6m), and its power device is also arranged in the middle position of the mechanism. This results in the trolley being very likely to roll over when the cathode plate placement position is offset, causing major safety accidents.
[0008] CN207347675U discloses a cathode plate conveying system and a zinc stripping unit, which includes a cathode plate placement rack for placing cathode plates, a chain conveyor, a transfer trolley and a guide mechanism. The transfer trolley can move back and forth between the cathode plate placement rack and the chain conveyor under the guidance of the guide mechanism. The inventors have found that the cathode plate transport device has at least the following problems:
[0009] (1) The transfer trolley is located at the bottom of the cathode plate placement rack. It is mainly a frame structure and has no protection or liquid diversion design. Therefore, when the cathode plate is lifted from the electrolytic cell to the plate placement rack, a large amount of acid will corrode the structural components and power components of the transfer trolley waiting there, which will not only greatly shorten the service life of the equipment, but may also cause safety accidents. If you choose to wait for the cathode plate to be lifted and placed on the chain conveyor, the waiting time will also be increased, resulting in the zinc stripping unit being unable to achieve true continuous operation. In addition, the design of the frame structure makes it very easy for the cathode plate to be squeezed or stuck with the moving transfer trolley when it falls from the placement rack or the carrier, making it difficult for the operator to quickly and effectively remove the cathode plate and troubleshoot, resulting in long downtime and low production efficiency.
[0010] (2) Although there is a placement slot on the cathode plate placement rack, there is no slot on the carrier. When the carrier lifts the cathode plate from the bottom, the position of the cathode plate is likely to change due to uneven force and other factors. When transported to the chain conveyor, the cathode plate that has changed position is likely to be unable to be correctly placed on the rack, resulting in plate drop and other faults, causing the automatic zinc stripping production line to stop.
[0011] (3) The transfer cart uses pneumatic drive to lift the cathode plate, but there is no power source or gas storage facility on the transfer cart. As a result, the pneumatic pipeline is too long to ensure the stability of lifting under heavy loads during operation. Especially during long-distance (more than 20m) transportation, it not only increases the power and energy consumption of the pneumatic system, but also greatly increases the risk of shutdown of the transfer cart.
[0012] CN111424293B discloses an automatic cathode plate transport and placement device for zinc stripping equipment and its operation method, the device includes a cathode plate transport trolley and a cathode plate placement rack. The transport device can move back and forth between the cathode plate placement rack and the chain conveyor under the guidance of a guide mechanism. The inventor found that the cathode plate transport device has at least the following problems:
[0013] (1) The transport trolley is arranged above the pallet rack. Although this facilitates maintenance and avoids severe corrosion caused by long-term accumulation of acid, it increases the space required for equipment layout. During operation, it may interfere with the overhead crane, resulting in a collision accident, which requires manual shutdown for processing.
[0014] (2) The carrier trolley uses a screw motor to drive the scissor mechanism to realize the lifting function of the cathode plate. However, since the screw motor is arranged on one side of the scissor mechanism, the scissor mechanism is prone to force imbalance during the lifting process. During the lifting and falling process, the screw motor may have stroke, overload and other faults, causing damage to the equipment and requiring manual shutdown for processing.
[0015] Therefore, in this field, a reliable, efficient, compact cathode plate docking device, as well as a good movement coordination relationship between the cathode plate carrier, cathode plate placement device, cathode plate transmission equipment and overhead crane under long distance and heavy load conditions are still problems that need to be solved.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0074] like Figures 1 to 13 As shown, the utility model provides an automatic plate connection device for a plate stripping device, which includes: a plate chain conveying device, a plate carrying device and a plate placing device, wherein the plate carrying device is located below the plate placing device. At the plate inlet end, the plate is placed on the plate placing device, and then the plate is carried to the plate chain conveying device by the plate carrying device. At the plate outlet end, the plates are arranged at equal intervals to the plate taking position on the plate carrying device by the plate chain conveying device. When the plates are full, the plate carrying device carries the full plates to the plate placing device.
[0075] In the technical solution of the utility model, at the plate inlet end of the automated stripping system, the plate automated docking device will receive the whole cathode plate hoisted from the electrolytic cell by the overhead crane, and transport it to the automated stripping system to perform the plate stripping operation; at the plate outlet end of the automated stripping system, the plate automated docking device will receive the plates that have completed the stripping and brushing operations and arrange them at a fixed spacing, waiting for the overhead crane to hoist them back to the electrolytic cell. The plate automated docking device of the stripping equipment can efficiently and stably deliver the plates into and out of the automated stripping system. At the same time, the plate transporting equipment is located below the plate placing equipment. The plate delivery operation process does not interfere with the operation process of the overhead crane hoisting the plates, which reduces waiting time, improves production efficiency, and provides conditions for the automatic zinc stripping equipment to continuously and uninterruptedly perform zinc stripping operations.
[0076] Specifically, in this embodiment, Figure 1 The schematic diagram of the plate stripping system with the plate automatic docking device is shown. A set of plate automatic docking devices are respectively provided at the plate inlet and plate outlet of the automatic plate stripping system, which are used to deliver the plates hoisted by the overhead crane to the docking position 1 of the automatic plate stripping system, and arrange the plates that have been stripped and scrubbed by the automatic plate stripping system at a fixed spacing, and return them to the electrolytic cell with the help of the overhead crane. The mechanical structures of the two sets of devices are exactly the same.
[0077] The plate stripping equipment plate automatic connection device includes a plate chain conveyor 2, a plate carrier 4 and a plate placement device. The number and position of the plate placement devices usually correspond to the arrangement of the electrolytic cells in the plant. Usually, the electrolytic cells in the electrolysis workshop are usually arranged in two spans in parallel, so the plate automatic connection device is usually arranged with two groups of plate placement devices, namely, the A column plate placement device 5 and the B column plate placement device 7. The mechanical structure and operation mode of the two groups of plate placement devices are exactly the same.
[0078] At the plate inlet, the plates 3 to be stripped in the electrolytic cell are hoisted to the plate automatic docking device by an overhead crane, placed on the plate placement device 5, and then transported to the plate chain conveyor 2 in two batches by the plate carrier 4. The plate chain conveyor 2 steps at equal intervals through the motor to send the plates 3 to be stripped into the automated plate stripping system for stripping. At the plate outlet, the plates 3 that have completed the stripping and brushing operations in the automated plate stripping system are arranged at equal intervals to the plate taking position of the plate carrier 4 by the plate chain conveyor 2. After the plates 3 are full, the plate carrier 4 transports the full plates 3 to the plate placement device 5 in two batches. After the A column of plates 6 on the plate placement device 5 is full, it is hoisted to the electrolytic cell by an overhead crane to enter the next cycle of the operation process.
[0079] The plate transport device 4 is located below the plate placement device 5 to avoid interference with the overhead crane, greatly improving the transfer efficiency of the overhead crane. At the same time, the plate transport device 4 adopts a modular structure design, which has more space in a limited space to maintain and clean the equipment, ensuring that the equipment has sufficient strength and reliability. The plate placement device 5 corresponds to the layout of the electrolytic cells in the factory building, and the plates in each span of the electrolytic cells do not interfere with each other, which greatly shortens the waiting time and improves production efficiency.
[0080] Plate chain conveyor equipment 2 Figure 2 , including a conveying equipment body 20, a chain transmission device 21, a tensioning device 22, a conveying motor reducer 23 and a conveying sensor assembly 24.
[0081] The chain transmission device 21 is composed of two groups of chain components of the same structure, which are distributed on both sides of the conveying equipment body 20. The stepping transportation of the plate is realized through the cooperation of the gear and the chain. Each chain section is designed with a toothed slot, which cooperates with the conductive beam of the plate 3 to limit the position of the plate 3 when the plate chain conveying equipment 2 horizontally transports the plate 3, so as to ensure the equidistant stepping of the plate 3. The two groups of chain components are coaxially connected to the first motor reducer 23 to realize the synchronous operation of the chain. The two groups of chains on both sides of the chain transmission device 21 are each equipped with a tensioning device 22. The tensioning device 22 pushes the tensioning device body 220 through the tensioning drive device 223, and cooperates with the linear guide assembly 222 to realize the tensioning effect of the chain. The tensioning device 22 is equipped with a tensioning sprocket 221 to cooperate with the chain to realize the movement of the chain in the tensioned state.
[0082] There are a total of 5 groups of conveying sensor components 24 of the electrode chain conveyor 2, of which 4 groups are arranged on the upper cross beam of the conveyor body 20, and are triggered by the conductive beam induction of the electrode 3, and are used to provide feedback signals of the electrode in place at the starting position, signal position, pick-up and place position and end position of the electrode chain conveyor 2.
[0083] At the plate feeding end, the proximity switch of the first conveying sensor assembly 24 is used to detect whether there is a plate at the head end of the equipment. When the proximity switch of the first conveying sensor assembly 24 has a signal, the plate chain conveying device 2 triggers the chain reverse movement self-locking function to prevent the plate 3 from falling, and the chain performs forward stepping movement. The proximity switch of the second conveying sensor assembly 24 is used to send a signal to the plate carrier 4 in the waiting position. When there is a plate 3 on the plate chain conveying device 2, the plate 3 will trigger the proximity switch of the second conveying sensor assembly 24 with each step of the chain. When the proximity switch of the second conveying sensor assembly 24 has no signal for a period of time, the plate carrier 4 starts to enter the plate chain conveying device 2 from the waiting position and prepares to place the plate 3. The proximity switch of the third conveying sensor assembly 24 is used to feedback the signal that the plate carrier 4 has placed the plate 3 in place. When the proximity switch of the third conveying sensor assembly 24 has a signal, it means that the plate carrier 4 has completed the placement operation of placing the unpeeled plate 3 on the plate chain conveyor 2, the plate chain conveyor 2 steps forward, and the plates move forward in turn and trigger the proximity switch of the third conveying sensor assembly 24. When the proximity switch of the third conveying sensor assembly 24 has no signal for a period of time, it means that there is no plate 3 at the plate placement position of the plate chain conveyor 2, and the plate carrier 4 can directly enter the plate chain conveyor 2 to place the next group of plates 3 without waiting at the waiting position. The proximity switch of the fourth conveying sensor assembly 24 is used to detect whether there is a plate 3 at the end of the equipment. When the proximity switch of the fourth conveying sensor assembly 24 has a signal, the plate chain conveyor 2 triggers the chain forward motion self-locking function to prevent the plate 3 from falling. At the same time, the automatic stripping system takes away the plate 3 through the corresponding equipment therein and enters the stripping operation process.
[0084] At the plate output end, the proximity switch of the first conveying sensor assembly 24 is used to detect whether there are plates at the head end of the equipment. When the proximity switch of the first conveying sensor assembly 24 has a signal, the plate chain conveying device 2 triggers the chain reverse movement self-locking function to prevent the plate 3 from falling. At the same time, the plate carrier 4 transports the entire group of plates 3 arranged equidistantly to the plate placement device 5. The proximity switch of the second conveying sensor assembly 24 is used to send a signal to the plate carrier 4 in the waiting position. When the proximity switch of the second conveying sensor assembly 24 has a signal, the plate carrier 4 starts to enter the plate chain conveying device 2 from the waiting position and prepares to extract the plate 3. The proximity switch of the third conveying sensor assembly 24 is used to feedback that the number of plates 3 taken by the plate carrier 4 meets the requirements. When the proximity switch of the third conveying sensor assembly 24 has a signal, it means that the number of plates 3 taken by the plate carrier 4 meets the production requirements. The proximity switch of the fourth conveying sensor assembly 24 is used to detect whether there is a plate 3 at the end of the equipment. When the proximity switch of the fourth conveying sensor assembly 24 has a signal, the plate chain conveying equipment 2 triggers the chain forward movement self-locking function to prevent the plate 3 from falling. At the same time, the chain performs reverse stepping motion to equidistantly arrange the plates 3 that have completed the stripping and brushing operations.
[0085] A proximity switch of the fifth conveying sensor assembly 24 is arranged below the conveying device body 20 to cooperate with the induction sheet of the fifth conveying sensor assembly 24 on the plate carrier 4 to achieve precise positioning of the plate carrier 4 when the plate chain conveyor 2 takes and places the plate 3.
[0086] Plate transport equipment 4 Figure 3 , including a carrying equipment frame 40, a horizontal wheel assembly 41, a wheel assembly 42, a track assembly 43, a carrying motor reducer 44, a pole plate lifting device 45, a pole plate bracket 46, a lifting drive device 47, a lifting guide device 48 and a carrying sensor assembly 49.
[0087] The horizontal wheel assembly 41 is connected to the front and rear ends of the left and right sides of the carrier frame 40 by bolts. A single horizontal wheel assembly 41 has two horizontally arranged wheels, which cooperate with the two side surfaces of a single guide rail respectively, to limit the position of the wheel assembly 4 and prevent it from derailing. The wheel assembly 42 is connected to the carrier frame 40 by bolts, and the wheel hub is slightly wider than the track to reduce the axial stress of the plate carrier 4 during operation. The inner and outer sides of the wheel are designed with wheel rims to guide the plate carrier 4. The track assembly 43 is laid on the ground foundation to enable the plate carrier 4 to move between the plate chain conveyor 2 and the multiple sets of plate placement equipment 5. The left and right sides and the front and rear ends of the guide rail are arranged with limit assemblies to limit the extreme position of the plate carrier 4 to prevent it from leaving the track from the front and rear ends and causing accidents. The carrier motor reducer 44 is installed on the inner side of the front end of the carrier frame 40 to drive the plate carrier 4 to move in the horizontal direction.
[0088] The plate lifting device 45 cooperates with the carrier frame 40 through the lifting guide device 48, and is the main mechanism for the plate carrier 4 to lift and place the plate 3. The plate bracket 46 is installed on the plate lifting device 45 by bolts, and performs the lifting and placement movement of the plate 3 together with the plate lifting device 45, and is the main mechanism that cooperates with the plate 3. The plate bracket 46 has a toothed slot with a spacing equal to that of the placement of the plate 3. The toothed slot cooperates with the conductive beam of the plate 3 to achieve the lifting and lowering of the plate 3, and at the same time limits the position of the plate 3, so that when the plate carrier 4 extracts or places the plate 3, the plate will not be stuck or fall off. The lower part of the lifting drive device 47 is fixed to the carrier frame 40, and the upper end is fixed to the plate lifting device 45. The plate lifting device 45 lifts and places the plate 3 by air pressure or hydraulic pressure. The transport trolley can lift a fixed number of plates 3 at a time, so that the plates can enter and exit the automatic plate stripping system fully automatically before and after the automatic plate stripping operation.
[0089] The plate carrier 4 has two groups of carrier sensor assemblies 49, which are arranged on both sides of the carrier frame 40, namely, the first carrier sensor assembly 49 and the second carrier sensor assembly 49. The induction sheet in the first carrier sensor assembly 49 and the induction sheet in the second carrier sensor assembly 49 are installed on the plate lifting device 45. When the lifting drive device 47 drives the plate lifting device 45 to rise close to the upper limit, the plate lifting device 45 drives the induction sheet in the first carrier sensor assembly 49 to enter the sensing range of its proximity switch, and the proximity switch sends a signal to cut off the power of the lifting drive device 47, so that the lifting drive device 47 stops moving, and the plate lifting device 45 stops at the upper limit.
[0090] When the lifting drive device 47 drives the plate lifting device 45 to descend and approach the lower limit, the induction sheet and the proximity switch in the second transport sensor assembly 49 use the same working principle to stop the plate lifting device 45 at the lower limit. The upper and lower limits of the plate lifting device 45 can be adjusted by adjusting the induction sheet. In addition, the induction sheet of the fifth conveying sensor assembly 24 is also installed at the rear end of the carrier frame 40, which is used to cooperate with the corresponding sensor assemblies on the plate chain conveyor 2 and the plate placing device when the plate carrier 4 moves horizontally on the track assembly 43, so as to achieve accurate positioning of the plate carrier 4 when taking and placing the plate 3.
[0091] Plate placement equipment 5 Figure 4 , including an equipment body 50, a toothed placement device 51, a sliding cable assembly 52, a crane positioning device 53 and a placement sensor assembly 54. The toothed placement device 51 is installed on the equipment body 50 by bolt connection, and is used to store the pole plates 3 that are hoisted or to be hoisted away. The toothed placement device 51 is provided with toothed slots with the same placement spacing as the pole plates 3. The toothed slots cooperate with the conductive beams of the pole plates 3 to limit the spacing and position of the pole plates 3. The crane positioning device 53 is installed on the equipment body 50 by bolt connection, and is used to position the crane that hoists the pole plates 3. At the plate inlet end, the crane that hoists the unpeeled pole plates 3 passes through the crane positioning device 53, and accurately places the pole plates 3 on the toothed placement device 51 of the pole plate placement device 5. At the plate outlet end, the crane is accurately positioned by the crane positioning device 53, and the pole plates 3 that have completed the peeling and brushing operations are hoisted off from the pole plate placement device 5. The sliding cable assembly 52 is installed on the equipment body 50 by bolt connection, and all pipelines, cables, etc. on the plate carrying equipment 4 that move with it are moved with the vehicle through the sliding cable assembly 52.
[0092] There are five sets of placement sensor components 54 of the electrode placement device 5 , two of which are arranged on the upper end cross beam of the device body 50 to detect whether two sets of electrodes are present on the electrode placement device 5 .
[0093] At the plate feeding end, when the crane lifts the unpeeled plates to the plate placement device 5, the proximity switches of the first placement sensor assembly 54 and the second placement sensor assembly 54 are triggered at the same time, and the plate transporting device 4 transfers the two groups of plates 3 to the plate chain conveying device 2 in batches, and then enters the automatic plate stripping system.
[0094] At the plate outlet, when the proximity switches of the first placement sensor assembly 54 and the second placement sensor assembly 54 are triggered simultaneously, the overhead crane lifts the two groups of stripped and scrubbed plates 3 on the plate placement device 5 back to the electrolytic cell at one time to enter the next production cycle.
[0095] The proximity switches of the third, fourth and fifth placement sensor assemblies 54 are arranged below the equipment body 50, respectively, and are used to cooperate with the induction sheet of the fifth carrying sensor assembly 49 on the plate carrier 4 to achieve accurate positioning of the plate carrier 4 at the waiting position, the first pick-up and placement position, and the second pick-up and placement position.
[0096] Taking the transportation of cathode plates in row A as an example, the steps and methods for transporting and placing the plate automatic docking device are described below.
[0097] ① After the overhead crane lifts the plate to the plate placement device 5 in row A at the plate entry end, the overhead crane can return to the electrolytic cell area to perform other operations. Figure 5 There are still plates on the plate chain conveyor 2 that have not yet entered the automatic plate stripping system 1, and the plate carrier 4 is waiting for the operation start signal at the initial position.
[0098] ② The plate transport equipment 4 at the plate entry end transports the plate to the initial position, see Figure 6 The cathode plates to be peeled in row A have been placed on the plate placement device 5, and the proximity switches of the first placement sensor assembly 54 and the second placement sensor assembly 54 have signals; at the same time, there are no plates 3 at the corresponding positions on the plate chain conveyor 2, and the proximity switch of the second conveyor sensor assembly 24 has no signal, and the plate carrier 4 moves to the right, preparing for the first transportation of the plates 3.
[0099] ③ The first plate taking position of the plate transport device 4 at the plate entry end is shown in Figure 7 The cathode plate carrier 4 moves to the right, and when the sensing piece of the fifth conveying sensor assembly 24 enters the sensing range of the proximity switch of the first placement sensor assembly 54, the proximity switch sends a signal and stops the cathode plate carrier 4 to reach the first plate taking position.
[0100] ④ The upper limit position of the first plate lifting of the plate carrier 4 at the plate entry end is shown in Figure 8 When the plate carrier 4 arrives at the first plate picking position, the proximity switch of the first placement sensor assembly 54 has a signal, and the plate lifting device 45 is lifted upward by the lifting drive device 47. When the induction sheet of the first carrier sensor assembly 49 enters the sensing range of the proximity switch of the first carrier sensor assembly 49, the proximity switch sends a signal, and the plate lifting device 45 rises to the upper limit position, lifting the first group of plates 3 until the conductive beam completely leaves the toothed placement device 51 of the plate placement device 5.
[0101] ⑤ Plate loading equipment 4 at the plate entry end Fig. 9The cathode plate carrier 4 moves to the left, and when the induction sheet of the fifth conveying sensor assembly 24 enters the sensing range of the proximity switch of the fifth conveying sensor assembly 24, the proximity switch sends a signal and stops the cathode plate carrier 4 to reach the plate placement position on the plate chain conveyor 2.
[0102] ⑥ The lower limit position of the plate lowering of the plate carrier 4 at the plate entry end is shown in Fig.10 When the plate carrier 4 reaches the plate placement position, the proximity switch of the fifth conveying sensor assembly 24 has a signal, and the plate lifting device 45 is driven downward by the lifting drive device 47. When the induction sheet of the second carrier sensor assembly 49 enters the sensing range of the proximity switch of the second carrier sensor assembly 49, the proximity switch sends a signal, and the plate lifting device 45 is lowered to the lower limit position, and the first group of plates is lowered until the conductive beam is completely placed on the chain transmission device 21 of the plate chain conveyor 2.
[0103] ⑦ The second plate taking position of the plate transport device 4 at the plate entry end is shown in Fig.11 After the cathode plate carrier 4 completes the first plate placement, it moves to the right again. When the sensing piece of the fifth conveying sensor assembly 24 enters the sensing range of the proximity switch of the second placement sensor assembly 54, the proximity switch sends a signal and stops the cathode plate carrier 4 to reach the second plate picking position.
[0104] ⑧ The second placement position of the plate carrier 4 at the plate entry end is shown in Fig.12 . The cathode plate carrier 4 adopts the same method as the first plate removal, lifting the second group of plates until the conductive beam completely leaves the toothed placement device 51 of the plate placement device 5, and then moves to the left. When the induction sheet of the fifth conveying sensor assembly 24 enters the sensing range of the proximity switch of the third placement sensor assembly 54, the cathode plate carrier 4 arrives at the waiting position and stops moving, waiting for the previous plate to enter the automatic plate stripping system 1. When the proximity switch of the second conveying sensor assembly 24 has no signal for a period of time, the plate carrier 4 continues to move to the left, and the induction sheet of the fifth conveying sensor assembly 24 enters the sensing range of the proximity switch of the fifth conveying sensor assembly 24. The proximity switch sends a signal and stops the cathode plate carrier 4, and reaches the plate placement position on the plate chain conveyor 2.
[0105] ⑨ Operation of plate end plate carrier 4 Fig.13At the plate-out side, the plates 3 that have been stripped and scrubbed by the automated plate-stripping system are arranged in equal steps through the plate chain conveyor 2. When the plates 3 step into the sensing range of the proximity switch of the second conveying sensor assembly 24, the plate carrier 4 enters the plate chain conveyor 2 from the waiting position, and transports the plates from the plate-taking position of the plate chain conveyor 2 to the toothed placement device 51 of the plate placement device 5 in sequence through a transportation method similar to that of the plate-in side.
[0106] At the plate inlet and plate outlet, the plate carrier 4 transports the plates 6 in column A to be entered into the automatic plate stripping system or have been stripped and the plates 8 in column B to be entered into the automatic plate stripping system or have been stripped, and the principle and operation process are exactly the same. In the actual production process, the production mode of using two columns at the same time or only using column A or column B can be selected according to the actual production volume on site.
