The automatic plate arranging machine 422 is a prior art, which is the invention patent "CN202210045787.8 A kind of automatic plate arranging machine for electrolytic manganese cathode plates" applied by the applicant.

[0040] The base frame 403 of the passivation plate arrangement transport vehicle 400 is provided with two sets of out-of-tank plate picking, placing and conveying assemblies 401 and in-tank plate picking, placing and conveying assemblies 402. The two sets of in-tank plate picking, placing and conveying assemblies 402 are symmetrically arranged on the left and right sides of the base frame 403, and the two sets of out-of-tank plate picking, placing and conveying assemblies 401 are arranged in the middle, respectively cooperating with two sets of independent automatic in-and-out tank devices 300, so as to simultaneously perform the operation actions of the electrolytic cell areas 103 on the left and right sides, thereby improving the operation efficiency of the cathode plates in and out of the tank.

[0041] like Fig.10 As shown, the RGV transporter 500 includes a frame and four plate channels arranged on the frame, including two inlet plate channels 501 located on both sides and two outlet plate channels 502 located in the middle. The inlet plate channel 501 transmits and transports the plates to the upper plate conveying chain 427 of the corresponding inlet plate pick-up and delivery assembly 402 through the operation of the inlet plate driver 511 and the inlet plate conveying chain 512. The outlet plate channel 502 receives and conveys the plates on the corresponding outlet plate lower plate conveying mechanism 417 through the operation of the outlet plate driver 521 and the outlet plate conveying chain 522. The four channels of the RGV transporter correspond to the four functional channels of the passivation plate transporter. The clean plates on the RGV transporter can be transferred to the upper plate position of the passivation plate transporter (as indicated by the arrow); and the plates with materials at the lower plate position of the passivation plate transporter can be transferred to the RGV transporter (as indicated by the arrow); and then transported to the subsequent production equipment area by the RGV transporter, realizing the complete operation process of automatic entry and exit of cathode plates in the slot.

[0042] The base frame 403 of the passivation plate transport vehicle 400 may also be provided with only one out-slot plate pick-up and transfer assembly 401 and one in-slot plate pick-up and transfer assembly 402. The frame of the RGV transport vehicle 500 may also be provided with only two plate channels, namely, one in-slot plate channel 501 and one out-slot plate channel 502.

[0043] The working process is as follows:

[0044] (1) The clean cathode plate is placed in the slot entry channel 501 of the RGV transporter 500 after the stripping process. The RGV transporter 500 is transported to the logistics channel 104 of the slot surface area (cathode plate entry and exit operation area) via the ground rail 105.

[0045] (2) The RGV transport vehicle 500 is aligned and docked with the passivation plate transport vehicle 400. Through automatic transfer, the clean cathode plate of the slot plate channel 501 of the RGV transport vehicle 500 is transferred to the upper plate conveying mechanism 425 of the slot plate loading and delivery assembly 402 of the passivation spray transport vehicle 400, completing the cathode plate loading operation.

[0046] (3) The clean cathode plates are driven by the upper plate conveying chain 427 and the chain drive 428, and the automatic plate arrangement machine 421 arranges the clean cathode plates at equal intervals on the toothed chain of the whole plate chain 424. At this time, the spacing and number of the clean cathode plates are consistent with the parameters of the corresponding diaphragm frames, waiting for the slot operation.

[0047] (4) The automatic tank loading and unloading device 300 automatically takes out the cathode plate containing the product in the previous electrolysis cycle from the diaphragm frame at the starting position according to the position setting of the automation program, and then places it on the placement chain of the out-tank plate placing and conveying mechanism 415 of the passivation plate arrangement transport vehicle 400. The out-tank operation of the cathode plate with the product is completed.

[0048] (5) The automatic in-and-out tank device 300 moves the guide in-and-out clamp 304 to above the position of the whole plate chain 424 described in step (3) by lateral movement, and then automatically grabs the same number of clean cathode plates to prepare for the tank entry operation.

[0049] (6) The automatic tank loading and unloading device 300 places the grabbed clean cathode plate into the empty diaphragm frame from which the cathode plate has been removed in step (4) through automated action, thus completing the operation of loading the cathode plate into the tank.

[0050] (7) The cathode plate with the product placed on the chain of the out-grooved plate placing conveyor mechanism 415 of the passivation plate arrangement transport vehicle 400 is conveyed by the chain, passes through the out-grooved plate automatic spraying device 416, completes the process requirements of wetting the cathode plate with the passivation liquid, and then is conveyed by another section of the chain to the out-grooved plate lower plate conveyor mechanism 417.

[0051] (8) The cathode plate with product on the lower plate conveying mechanism 417 is automatically transferred to the chain of the outlet plate channel 502 of the RGV transport vehicle 500 docked here. At this time, the RGV transport vehicle 500 completes the exchange action of the clean cathode plate and the cathode plate with product.

[0052] (9) The left and right automatic in-and-out tank devices 300 synchronously complete the cathode plate in-and-out tank operations of the left and right electrolytic tank areas 103.

[0053] (10) The RGV transport vehicle 500 carries the cathode plate with the product back to the post-stripping process area, completing a complete exchange operation of the cathode plate in and out of the tank between the previous and next processes.

[0054] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments.
