Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery plate coating device, more particularly to a lead-acid battery plate coating device. BACKGROUND

[0002] The lead-acid battery plate coating is the core process of battery manufacturing, which fills the lead paste uniformly to the grid framework through the paste coating device to form the electrochemical reaction active material. The traditional coating process adopts an open slurry tank matched with a scraper to smear, and the lead paste is prone to solid-liquid separation due to gravity settlement in the conveying process, and needs to be continuously mechanically stirred to maintain the rheological properties. This method faces problems such as uneven density of lead paste, fluctuation of coating thickness, etc. in continuous production, which directly affects the consistency of the plate capacity and the cycle life of the battery, especially in high temperature and high humidity environment, the evaporation of lead paste moisture accelerates the hardening in the gap of the equipment, which needs frequent shutdown for cleaning, and restricts the production efficiency.

[0003] Therefore, in the prior art, a double-roller paste coating intelligent production line is generally used to optimize the above problems, which extrudes and conveys the stored lead paste through a steel roller surface or a rubber coated roller, and prevents the lead paste from hardening by placing a spiral stirring device in the bin, however, in order to improve the bonding force of the lead paste and the grid, the production line needs to add an activation spraying process before coating, such as spraying dilute sulfuric acid or organic binder, but the physical mixing of the spraying reagent and the lead paste is not in situ chelation, which leads to uneven distribution of additives, and some technologies try to pre-mix the activator in the stirring bin, but the high density characteristics of the lead paste make the light additives float and separate, which further exacerbates the composition segregation.

[0004] And the root cause of the contradiction lies in that the existing device cannot realize the in-situ activation of solid reducing agent and the source control of impurity ions. Since the double-roller system needs to maintain high viscosity of the lead paste to ensure the forming property of the coating, it cannot directly incorporate the moisture-sensitive solid reducing agent, and the external spraying of the activation liquid can temporarily improve the bonding force, but it is difficult to activate the reducing agent activity and chelate heavy metal impurities due to the inability to penetrate the lead paste synchronously, which leads to the migration of impurity ions to the active material grain boundary when the plate solidifies, forming a dendrite short circuit point. The current structure is limited by the closed nature of the stirring bin and the dynamic nature of the roller pressing, which cannot realize the moisture-proof storage of the reducing agent, nor does it lack the micro-area mixing mechanism of the lead paste and the chelating agent, ultimately affecting the electrochemical stability of the regenerated plate.

[0025] As shown in the drawings, in order to clearly realize the structure of the embodiments of the present application, specific structures and devices are marked in the drawings, but this is only for the need of illustration, and is not intended to limit the present application in the specific structures, devices and environments, and the devices and environments can be adjusted or modified by those skilled in the art according to specific needs. Figures 1 to 9 As shown in the drawings, in order to clearly realize the structure of the embodiments of the present application, specific structures and devices are marked in the drawings, but this is only for the need of illustration, and is not intended to limit the present application in the specific structures, devices and environments, and the devices and environments can be adjusted or modified by those skilled in the art according to specific needs. The lead storage battery plate coating device provided by the embodiment of the present application comprises a plate conveying belt 1, a coating device and an extrusion roller 7, the coating device is wholly covered on the conveying end surface of the plate conveying belt 1 through a sealing cover, the coating device comprises a bidirectional servo drive frame unit 2 and a coating mechanism 4, the bidirectional servo drive frame unit 2 is arranged on the conveying end surface, and the coating mechanisms 4 are respectively arranged at positions symmetrically located on both sides of the surface of the bidirectional servo drive frame unit 2, and the coating mechanisms 4 on both sides are aligned with the plate conveyed on the plate conveying belt 1 to perform S-shaped paste coating treatment through the bidirectional drive of the bidirectional servo drive frame unit 2; The smearing mechanism 4 comprises a disc cover 41, and the top of each disc cover 41 is provided with a paste awakening mechanism 5, which comprises a storage tank 51 for storing lead paste, wherein the inner axial position of the storage tank 51 is further provided with a separate storage cavity 55 for storing active reagents, and the inner axial position of the disc cover 41 is further provided with a real-time mixing stirring mechanism 8, and the storage tank 51 is connected with the disc cover 41 through a second conduit 49, and the storage tank 51 is connected with the stirring mechanism 8 through a first conduit 48; The lead paste and the active reagents are separately stored by the paste awakening mechanism 5, the lead paste and the active reagents are mixed in real time on the smearing end of the plate by the stirring mechanism 8, and the smearing is realized by extruding the paste outwards through the disc cover 41 to achieve the source chelation of the material.

[0026] In order to solve the problem of synchronous penetration and uniform mixing of lead paste and activator in the existing lead-acid battery plate smearing process, and improve the electrochemical stability of the plate and the cycle life of the battery, the above technical scheme is adopted to solve the problem. The above technical scheme mainly comprises a plate conveying belt 1, a smearing device, and an extrusion roller 7. The plate conveying belt 1 and the extrusion roller 7 are inherent structures of the conventional smearing device in the prior art. The plate conveying belt 1 is an electric track structure controlled by a servo motor, which is used to convey the battery plate to be smeared with lead paste. The extrusion roller 7 is a device controlled by a servo drive end and a circular roller, which is used to extrude and smear the battery plate with lead paste, so that the lead paste is fixed in the recess of the battery plate, and the extrusion and shaping functions are realized. The smearing device comprises a bidirectional servo drive frame unit 2 and a smearing mechanism 4. The bidirectional servo drive frame unit 2 is used to control the left and right smearing mechanisms 4 to move back and forth to align the plate conveyed by the plate conveying belt 1 and perform S-shaped paste smearing treatment. The speed of the back and forth movement is used to control the path of paste smearing of each side smearing mechanism 4. Unlike the smearing method using a roller in the prior art, the area of smearing can be controlled by controlling the interval of left and right back and forth movement, and the waste of unnecessary smearing area is reduced. On the other hand, unlike the uninterrupted type of paste smearing by a roller, the double-sided controllable smearing mechanism 4 can also cooperate with the detection end and the reverse conveying of the plate conveying belt 1 to position and supplement the paste recess.

[0027] The smearing mechanism 4 as the paste smearing end comprises a disc cover 41, which is essentially a transplanted smearing terminal. The paste and the active reagents are mixed in real time before smearing, and the paste is activated after extruding the paste and before smearing, so that the source chelation of the material is realized without disturbing the storage of the paste.

[0028] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 ,Figure 9 As shown, the bidirectional servo drive frame unit 2 includes a rectangular guide rail frame 21 fixed on the upper side of the plate conveying belt 1, a first servo motor 22 is fixedly installed on one side end of the rectangular guide rail frame 21, a bidirectional threaded rod 23 is fixedly installed on the output end of the first servo motor 22, the bidirectional threaded rod 23 penetrates into the inner side of the rectangular guide rail frame 21, and a partition plate is fixedly installed at the position of the middle end of the inner side of the rectangular guide rail frame 21, the disc cover 41 is slidingly installed at positions symmetrically located on both sides of the partition plate of the rectangular guide rail frame 21, and a nut sleeve 45 engaged with the bidirectional threaded rod 23 is fixedly installed at the position of the center of each disc cover 41, and the outer surface of the rectangular guide rail frame 21 is fixedly installed with a scanning module 3 at positions corresponding to the front and rear sides of the conveying direction of the plate conveying belt 1.

[0029] Among them, the first servo motor 22 configured is a motor structure capable of servo drive control in the prior art, the bidirectional threaded rod 23 of the control output end is servo rotated, in the process of rotation, the disc cover 41 engaged by the motor reciprocates back and forth along the rectangular guide rail frame 21 on both sides of the partition plate, by controlling the reciprocating interval and the moving speed in the moving process, the coverage path of the paste end of the two disc covers 41 can be changed, that is, the S-shaped coverage area, in the control process, the scanning module 3 on the front and rear sides is used to scan the battery plate, that is, the grid sheet, entering the smearing area, on the one hand, the actual size of the grid sheet is scanned out, providing data support for the reciprocating movement of the disc cover 41 in the later smearing, on the other hand, whether the grooves of the grid sheet after smearing are evenly smeared and whether there is lack of paste are scanned out, so as to facilitate the reverse conveying of the plate conveying belt 1 to smear again accurately, the scanning module 3 configured is a camera device with infrared scanning and temperature sensing functions in the prior art.

[0030] Specifically, the scanning module 3 arranged behind the extrusion roller 7 uses the high-precision infrared thermal imager to realize defect detection by using the difference in thermodynamic characteristics during the curing of the lead paste. First, the thermal conduction difference is captured. The complete pasting area forms a uniform thermal conduction layer due to the coverage of the lead paste, and the temperature distribution is continuous during curing. The paste-free area is directly exposed to the metal substrate, which reduces the heat capacity and speeds up heat dissipation, resulting in a local temperature significantly higher than the surrounding area. The infrared thermal imager scans the surface of the pole plate of the extrusion roller 7 at a rate of 30 frames per second, generating a real-time temperature distribution map. The software automatically marks the temperature abnormally high area, which is the paste-free area, by comparing the temperature changes of the same pole plate before and after extrusion, and records its accurate coordinates, such as the lower left corner of the pole plate as the origin, the defect located at X=120mm, Y=35mm. Non-contact detection avoids physical damage and has strong penetration, and is not affected by the reflection or texture of the pole plate surface. The control end system of the motor realizes closed-loop control from detection to repair through coordinate mapping. The scanning module 3 records the pole plate profile and groove distribution in advance, the infrared system superimposes the defect coordinates on the digital model of the pole plate, generates a path with defect coordinates, and drives the pole plate conveyor belt 1 to move reversely, so that the defect coordinates are accurately returned to the bottom of the pasting mechanism 4. This process can be controlled through the encoder feedback to realize closed-loop control. During the adjustment process, the pasting mechanism 4 can be adjusted adaptively. The bidirectional servo drive frame unit 2 controls the horizontal movement of the disc cover 41 to the position directly above the defect coordinates. Therefore, in order to ensure the stability of the closed-loop control and the fixing strength of the paste, the temperature of the pasting end paste will be increased in the future.

The configured detachable valve head 410 and paste outlet cover 411 are integrated structures, which can be disassembled for maintenance and cleaning in real time, the paste outlet cover 411 is a rectangular material guide cover, which can improve the smearing area, and the valve body in the inside of the detachable valve head 410 is an electric control valve body.

[0040] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, the lower cavity in the partitioned storage chamber 55 is fixedly installed with an active agent delivery cavity 58, the active agent delivery cavity 58 is made of high thermal conductivity material, and the bottom of the active agent delivery cavity 58 is connected with the first conduit 48 extending into the storage tank 51. The upper cavity in the partitioned storage chamber 55 is fixedly installed with a filter disc 510 through the outer surface of the outer gas guide cover tube 57, and a plurality of through openings 511 are circumferentially arranged at the upper side of the filter disc 510 in the upper cavity of the partitioned storage chamber 55.

[0041] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the outer side of the rectangular guide rail frame 21 is fixedly installed with a gantry tooth plate frame 9, the outer edge of the embedded gear cover disc 52 is fixedly arranged with a tooth opening, and the tooth opening is engaged with the gantry tooth plate frame 9. The sidewall of the storage tank 51 is arranged with a paste supplementing conduit, and the outer scraping block 87 is fixedly installed on the conduit of the Y-shaped conduit 85. The outer scraping block 87 is made of high thermal conductivity material.

[0042] The outer scraping block 87 on the conduit of the arranged Y-shaped conduit 85 is an integral structure with the Y-shaped conduit 85 and is made of high thermal conductivity material. In the wall scraping process, heat is generated due to friction, and the heat is applied to the inner wall of the disc cover 41 and the entire Y-shaped conduit 85 along the Y-shaped conduit 85.

[0043] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the rectangular guide rail frame 21 is further arranged with a double-layer reset air bag unit 6 between the outer sidewalls of the two storage tanks 51. The double-layer reset air bag unit 6 includes an outer inflatable air bag 61, and the outer layer conduit of the double-layer conduit 56 is connected to the outer inflatable air bag 61. The inner liquid suction air bag 62 is fixedly installed in the inner layer conduit of the double-layer conduit 56. The liquid suction conduit 63 is fixedly installed on the sidewall of the inner liquid suction air bag 62 and penetrates through the outer inflatable air bag 61. A plurality of capillary adsorption openings are arranged on the outer inflatable air bag 61.

[0044] The configured double-layer reset air bag unit 6 is essentially an inner and outer double-layer reset air bag structure. The outer air bag 61 is contracted in the extrusion state, discharges the gas in the cavity, and the discharged gas is discharged through the outer layer of the double-layer conduit 56. In the expanded state of the outer air bag 61, the gas is reabsorbed for the next time of discharging the gas. The inner layer of the double-layer reset air bag unit 6 is the inner liquid suction air bag 62, which acts as a conversion pump during the expansion and contraction process. In the contraction state, the internal liquid is discharged through the inner layer of the double-layer conduit 56. In the expanded state, due to the action of negative pressure, the liquid is absorbed from the outside through the liquid suction conduit 63 for the next time of discharging. Therefore, in order to ensure the stability of the overall system, the joint end of the double-layer conduit 56 is configured with a one-way valve, and the liquid suction conduit 63 outside is used to connect the reagent supplement tank, and a one-way valve is configured to prevent liquid backflow.

[0045] The configured smearing mechanism 4 specifically smears the work as follows: Firstly, after the start of the electrode plate conveying belt 1, the grid plate to be smeared with lead paste is conveyed to the bottom of the smearing mechanism 4. Before entering the smearing mechanism 4, the smearing area of the smearing mechanism 4 and the frequency of reciprocating smearing are determined by the scanning module 3.

[0046] Then, the bidirectional threaded rod 23 at the output end of the first servo motor 22 controls the two circular cover plates 41 to smear according to the predetermined frequency and path. In the process of reciprocating movement of the circular cover plate 41 along the rectangular guide rail frame 21, the paste smearing mechanism 5 and the double-layer reset air bag unit 6 are synchronously driven to work together.

[0047] Among them, for the paste smearing mechanism 5, the embedded gear cover disc 52 movably installed at the top of the storage tank 51 rotates under the action of meshing gantry tooth plate frame 9. In the process of rotation, the special-shaped stirring plate 53 on the bottom surface of the embedded gear cover disc 52 rotates. Under the action of the stirring end, the special-shaped stirring plate 53 can also scrape the side wall of the inner cavity and transport heat to the cavity and the partition storage cavity 55 by friction heating, which can facilitate paste smearing and also make the smeared paste have a certain temperature, facilitating scanning by the scanning module 3.

[0048] For the double-layer reset air bag unit 6, during the translation of the disc cover 41, the storage tank 51 on both sides of the rectangular guide rail frame 21 will cause the outer inflatable air bag 61 and the inner liquid absorbing air bag 62 connected between the two storage tanks 51 to be reciprocally extruded and expanded. During the extrusion process, the gas extruded from the outer inflatable air bag 61 enters the upper cavity of the separated storage cavity 55 through the outer layer conduit of the double-layer conduit 56, and is discharged at the bottom of the filter disc 510 through the outer air guide cover pipe 57, and is discharged outward from the through hole 511 after passing through the filter disc 510, and acts on the top of the storage tank 51, that is, acts on the top of the storage end lead paste, so that the top of the paste of the storage end has a downward extrusion force, and the active reagent stored in the inner liquid absorbing air bag 62 enters the injection conduit 59 of the separated storage cavity 55 through the inner layer conduit of the double-layer conduit 56, and is injected into the active agent delivery cavity 58 through the injection conduit 59, and the reagent stored in the active agent delivery cavity 58 is heated by the heat conduction of the external special-shaped stirring plate 53, so that the temperature is increased, and the characteristics of the activated paste are improved.

[0049] Then, the extruded paste enters the inside of the disc cover 41 through the second conduit 49, and the heated reagent enters the inside of the active agent temporary storage annular cavity 47 through the first conduit 48, the reagent entering the inside of the active agent temporary storage annular cavity 47 flows into the particle storage cavities 82 on both sides, and then flows into each Y-shaped conduit 85 on the circular ring seal 84 through the particle storage cavities 82, and finally is sprayed outward through the Y-shaped conduit 85 to mix with the entering paste in the inside of the disc cover 41 to instantly generate the paste with smearing, and in the cavity, the Y-shaped conduit 85 is rotated and stirred by the rotation of the electrically controlled magnetic suction gear plate 44 driven by the gear plate 43 at the output end of the second servo motor 42, and in the process, the paste is continuously given temperature by the outer scraping block 87, and finally the paste is discharged from the paste discharge cover 411 by controlling the detachable valve head 410.

[0050] Finally, after ensuring that the grid plate is evenly smeared by the scanning of the scanning module 3, the plate pieces are conveyed to the bottom of the extrusion roller 7 by the plate conveying belt 1, and are extruded and shaped by the extrusion roller 7.
