AI Technical Summary
In dry environments, the plates lose water too quickly during the plate collection process, resulting in substandard plate quality and affecting battery performance. This is especially true in low-humidity regions such as Xinjiang, where existing technologies struggle to effectively maintain moisture during continuous operation.
Two symmetrically arranged humidifying rings are set in the plate collection area. The humidifier atomizes pure water to generate moisture. The humidifying rings and the connecting pipeline system create a saturated vapor pressure environment during the plate collection process, thereby reducing the rate of water loss from the plate.
It enables continuous operation and moisturization during the plate collection process in a dry environment, ensuring plate quality and avoiding quality problems caused by excessive water loss. It is suitable for production needs in low-humidity areas such as Xinjiang.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lead-acid batteries, specifically relating to a plate moisture retention fixture. Background Technology
[0002] During the production of lead-acid battery plates, after the wet raw plates are coated, the surface of the plate 7 is dried in a drying kiln, and then the plate 7 is stacked on the curing rack in the plate collection area using equipment such as stacking devices and robotic arms.
[0003] The curing rack is placed on the base by a forklift. The base is fixed to the ground by the base fixing block 3. The curing rack fixing seat 8 is placed on the base frame 10. The curing rack includes the curing rack column 7, the curing rack base plate 11, etc.
[0004] Before stacking the plates, arrange them in 17 layers, with 40-60 plates per stack. Each layer should be arranged according to... Figure 2 The plates are stacked in a 4x5 pattern, forming 20 stacks. Then, a PP board (18mm) is placed on each of the 20 stacks using a robotic arm. This process is repeated for a total of 5 layers.
[0005] During normal production, it takes 25-35 minutes to fill one curing rack. After one curing rack is filled, the robot arm starts to place the electrode plate 17 on another curing rack. The filled curing rack is then forked into the curing chamber by a forklift to begin the curing process.
[0006] If the plates lose too much water before entering the curing chamber for humidification, the plates will become substandard (such as low plate strength, incomplete lead conversion, paper shedding, etc.), which will affect the battery performance.
[0007] In areas with high ambient humidity, the plates lose less water, resulting in a lower impact on plate quality. However, in areas with extremely low ambient humidity (such as Xinjiang), where the actual vapor pressure is much lower than the saturated vapor pressure, water molecules on the plate surface can more easily break through the liquid phase and enter the gas phase. Therefore, the plate loses water more quickly, significantly impacting plate quality and requiring special control. Summary of the Invention
[0008] The purpose of this invention is to overcome the above-mentioned shortcomings of the prior art and to provide a continuously moisturizing fixture for the electrode plate receiving area, which enables continuous production without stopping the machine during the electrode plate receiving and transfer process, thereby achieving electrode plate moisturization during continuous operation.
[0009] The technical solution of this utility model is: a continuous humidification fixture for an electrode plate receiving area, comprising two symmetrically arranged humidifying rings disposed in the electrode plate receiving area, forming a working space for a receiving robot between the two humidifying rings, and the inner ring of the humidifying rings forming a receiving area for accommodating a curing rack for holding the electrode plates to be stacked; the humidifying rings are assembled from PVC pipes and pipe fittings, and each humidifying ring has a moisture outlet arranged around its inner ring; the two humidifying rings are connected by a connecting pipe, the connecting pipe comprising two connecting pipe sections respectively connected to each humidifying ring, the inlet of the connecting pipe section connecting to the main pipe section of a moisture diversion tee and connecting to the branch pipe section of the moisture diversion tee and connecting to the outlet of the humidifier; each connecting pipe section is equipped with a manual flap valve, and the manual flap valve has a flap valve handle.
[0010] The PVC pipe is a four-section pipe fitting. The pipe joint includes three PVC bends and one PVC tee. The inlets of the three PVC bends are connected to the outlets of the connecting pipe sections.
[0011] The notch on the upper inner side of the PVC pipe forms a moisture outlet.
[0012] The curing rack for the electrode plates to be stacked is stacked on the base frame at the bottom, and the humidifying ring is placed on the bottom surface of the electrode plate receiving area. The height of the humidifying ring is lower than the bottom plate of the curing rack for the electrode plates to be stacked on the base frame.
[0013] The electrode plate receiving area is enclosed by a fence, with an exit on the front side of the fence and an installation position on the back side that cooperates with the electrode plate conveyor belt.
[0014] The humidification ring is positioned near the outlet of the electrode plate receiving area on one side, while the humidifier is positioned outside the electrode plate receiving area.
[0015] Two symmetrical humidifying rings are arranged in the plate receiving area. The curing racks for the plates to be stacked are placed on the base frame within the humidifying rings. The arrangement of the two curing racks and humidifying rings ensures uninterrupted production and achieves plate humidification during continuous operation. In areas with excessively dry climates (such as Xinjiang), humidifiers are installed at the plate receiving area to increase the air humidity in the plate stacking environment and reduce plate water loss. During operation, the humidifier atomizes pure water, which then emerges from multiple moisture outlets, creating a high-humidity environment (reaching saturated vapor pressure) around the curing racks. The moisture flows with the airflow into the gaps between the stacked plates, reducing the actual water loss rate of the plates. If there are no plates on the curing racks in one of the humidifying rings, the manual flap valve can be closed by turning the flap valve handle, concentrating the moisture supply to the side with plates.

Detailed Implementation
[0022] Figure 1-5 In the electrode plate receiving area, stacked single-layer electrodes are conveyed by electrode plate conveyor belt 1, then picked up by a robotic arm mounted on a robotic arm base, and stacked on curing rack 4 according to process requirements (to ensure uninterrupted production, there are two curing racks, one on each side). For safety, the entire area is enclosed by fence 3. To facilitate the transfer of the curing racks 4 with stacked electrodes, there are gaps in the fence 3 on the outer sides of the two curing racks 4, allowing forklifts to drive in and transfer the curing racks 4 away.
[0023] The moisture generated by the commonly used industrial humidifier 6 enters the moisture distribution tee 5 and is then transferred to the humidification rings on both sides.
[0024] There are two curing rack bases on the left and right sides. Each curing rack base includes a base fixing block 9 and a base frame 10. The curing fixing seat 8 of the curing rack 4 is placed on the base frame 4. The curing rack 4 also includes a curing rack column 7 and a curing rack base plate 11.
[0025] Moisture from the moisture diversion tee 5 passes through the manual flap valve 12 and enters the humidification ring. The humidification ring consists of one PVC tee 13, three PVC bends, and four PVC pipes with quarter-circle openings. This surrounds the curing rack.
[0026] Connect the moisture inlet 8 to one side of the PVC tee pipe 13, and connect it to the humidifier 6. Connect the other two ports of the PVC tee pipe 13 to PVC pipes, and use three PVC bends 15 to surround the curing rack, forming a ring. Cut moisture outlets 14 evenly along the PVC pipe using a cutting machine. Moisture outlets 14 (e.g., ...) Figure 4 It is formed by cutting off 1 / 4 of the PVC pipe (near the top of the curing rack).
[0027] Moisture in the humidifying ring escapes through moisture outlet 14. Moisture outlet 14 is evenly distributed along the PVC pipe and is formed by cutting off 1 / 4 of the PVC pipe (near the top of the curing rack). Figure 4 ).
[0028] The height of the humidifying ring is the same as the height of the base frame 10 of the curing rack. The forklift lifts the curing rack from the ground of the base plate 11 of the curing rack, and the humidifying ring does not affect the operation of the forklift.
[0029] During the electrode production process, the humidifier atomizes pure water, which then emerges from multiple moisture outlets 14, creating a high-humidity environment (reaching saturated vapor pressure) around the curing rack. The moisture flows with the air and enters the gaps between the stacked electrode plates, reducing the rate of water loss from the electrode plates.
[0030] In addition, if there is no electrode plate on one side of the curing rack during the operation of the equipment, the manual flap valve 12 can be closed by turning the flap valve handle 16, so that the moisture is concentrated and supplied to the side with the electrode plate.
