Description

Technical Field

[0001] The invention relates to the technical field of battery substrate processing, and in particular to a battery substrate hole forming process. Background Art

[0002] The performance of the battery substrate directly affects the overall efficiency and service life of the battery. After the battery substrate (i.e., the plate) is formed, it needs to react chemically with sulfuric acid to achieve energy storage and release. Since the substrate has a certain thickness, the effective contact between the lead dioxide and sulfuric acid inside it becomes the key to increasing the reaction rate. Therefore, the porosity of the battery substrate needs to be further improved.

[0003] In the prior art, the raw materials are generally added to a stirring kettle and stirred evenly. In order to increase the porosity, a certain amount of perborate is added to the stirring kettle at the feed port. To ensure the uniformity of the porosity distribution, the perborate additive needs to be evenly dispersed in the paste. The perborate additive begins to decompose during the curing and drying stage, generating gas or volatile substances inside the plate, thereby forming pores and increasing the porosity.

[0004] However, in the above scheme, the perborate additive directly enters the stirring tank from the feed port, and the poured additive will accumulate in one place of the stirring tank, so that the agitator needs a longer time to fully mix the perborate into the raw materials, which greatly increases the time for the paste production. Summary of the invention

[0005] The purpose of the present invention is to provide a battery substrate hole forming process to solve the problems in the prior art.

[0006] The technical problem to be solved by the present invention can be achieved by the following technical solutions:

[0014] As a further solution of the present invention: the driving assembly drives the stirring structure to work, and the driving structure includes a synchronous ring and a synchronous wheel. The synchronous ring is fixedly connected to the outside of the material storage barrel and is used to drive the material storage barrel to rotate. The synchronous wheel is rotatably connected to the top of the mixing kettle. A synchronous belt is provided between the synchronous ring and the synchronous wheel. A motor is also fixed on the top of the mixing kettle. The output shaft of the motor is coaxially connected to the synchronous wheel. The rotation of the motor can drive the synchronous wheel, the synchronous ring and the material storage barrel to rotate synchronously.

[0015] As a further scheme of the present invention: the temperature control structure includes an internal temperature control component and an external temperature control component. The temperature of the paste mixing process is controlled by two groups of temperature control components during the stirring process, and the temperature is lowered to ensure that the additives are stably dispersed and not decomposed during the paste mixing process. The internal temperature control component includes an inlet bend and an outlet bend. Hollow grooves are provided at both ends of the rotating column. The two ends of the rotating column are respectively connected to the inlet bend and the outlet bend for rotation. The ends of the inlet bend and the outlet bend away from the rotating column are respectively connected to the water outlet and the water inlet of the water circulation device. The end of the outlet bend passes through the side wall of the discharging barrel and is fixedly connected to the discharging barrel. A number of bent heat exchange tubes are connected between the two hollow grooves of the rotating column. The cooling water inside the heat exchange tube can exchange heat with the heat inside the raw material and the heat generated by stirring.

The driving end of the collision ball cooperates with the electromagnetic telescopic rod, and whether the elastic member is extended or not controls whether the vibration component works.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1-Figure 8 As shown, a battery substrate hole forming process, the specific steps are as follows:

[0035] The first step is to put the raw materials into the mixing kettle 1 from the feed port 12 and use the stirring structure to mix them evenly;

[0036] The second step is to uniformly add the perborate into the mixing kettle 1 through the dispersion component. The dispersion component includes a storage barrel 21 for storing the perborate and an umbrella-shaped plate 5 for guiding the perborate. The storage barrel 21 is rotatably connected to the top of the mixing kettle 1, and the umbrella-shaped plate 5 is fixedly connected to the bottom of the storage barrel 21, wherein the bottom plate of the storage barrel 21 is the top of the umbrella-shaped plate 5. When discharging, the additive inside the storage barrel 21 can flow to its edge, so that the additive inside the rotating column 2 is discharged more fully. The storage barrel 21 is provided with a plurality of circumferential openings on the side surface. The long through holes 71 are used as openings, and the long through holes 71 are all arranged at the lower end of the storage barrel 21 for easy discharge. The umbrella-shaped plate 5 is evenly penetrated and provided with a plurality of bulk holes 51 for the perborate to fall on the outside of the storage barrel 21. The additives slide down along the inclined surface of the umbrella-shaped plate 5 and leak out from the bulk holes 51 or the edge of the umbrella-shaped plate 5 for discharge, which can prevent the additives poured into the mixing kettle 1 from accumulating in a corner inside the mixing kettle 1. Then, the stirring structure is used for full stirring, and the temperature of the paste process is controlled by the temperature control structure during the stirring process.

[0037] like Figure 3 As shown, the stirring structure includes a rotating column 2 and a driving assembly. The rotating column 2 is fixedly connected to the umbrella-shaped plate 5, and the rotating column 2 can rotate together with the storage barrel 21. A plurality of stirring shafts 4 for stirring raw materials are fixedly distributed circumferentially on the upper end of the side surface of the rotating column 2, and a plurality of stirring blades 41 for stirring bottom raw materials are fixedly arranged circumferentially on the lower end of the side surface of the rotating column 2. The bottom end of each stirring blade 41 cooperates with the side wall of the mixing kettle 1 to reduce dead corners and retention during the stirring process. A plurality of holes 42 are opened on each stirring blade 41. The holes 42 can increase the fluidity of the material. The holes 42 can cause the material to produce shearing, dispersion and mixing effects when passing through the stirring blade 41, which is helpful to achieve full mixing and uniform dispersion of additives and raw materials.

[0038] like Figure 2As shown, the driving assembly drives the stirring structure to work, and the driving structure includes a synchronous ring 22 and a synchronous wheel 23. The synchronous ring 22 is fixedly connected to the outer side of the material storage barrel 21, and is used to drive the material storage barrel 21 to rotate. The synchronous wheel 23 is rotatably connected to the top of the mixing kettle 1, and a synchronous belt 24 is provided between the synchronous ring 22 and the synchronous wheel 23. A motor 25 is also fixedly connected to the top of the mixing kettle 1. The output shaft of the motor 25 is coaxially fixedly connected to the synchronous wheel 23. The rotation of the motor 25 can drive the synchronous wheel 23, the synchronous ring 22, and the material storage barrel 21 to rotate synchronously.

[0039] like Figure 3 As shown, the temperature control structure includes an internal temperature control component and an external temperature control component. During the mixing process, the temperature of the paste mixing process is controlled by two sets of temperature control components. By lowering the temperature, the additive is ensured to be stably dispersed and not decomposed during the paste mixing process. The internal temperature control component includes an inlet elbow 3 and an outlet elbow 32. Hollow grooves are provided at both ends of the rotating column 2. The openings at both ends of the rotating column 2 are respectively connected to the inlet elbow 3 and the outlet elbow 32 for rotation. The ends of the inlet elbow 3 and the outlet elbow 32 away from the rotating column 2 are respectively connected to the outlet and the inlet of the water circulation device, so as to realize the circulation of cooling water and cool the material. Heat exchange, the end of the water outlet elbow 32 passes through the side wall of the discharge barrel 13 and is fixedly connected to the discharge barrel 13. A plurality of curved heat exchange tubes 31 are connected between the two hollow grooves of the rotating column 2. The curved heat exchange tubes 31 can increase the contact area with the material and improve the cooling effect. The cooling water inside the heat exchange tube 31 can exchange heat with the heat inside the raw material and the heat generated by stirring. The external temperature control component includes a cooling tube 14, which is arranged around the side wall of the mixing kettle 1. The interior of the cooling tube 14 is used to transmit cooling water to cool the material close to the side wall of the mixing kettle 1.

[0040] like Figure 6-8 As shown, a flow regulating component is arranged inside the storage barrel 21, and the flow regulating component includes a gate cylinder 7 for blocking the long through hole 71, each of the long through hole 71 is arranged vertically, and the gate cylinder 7 is slidably connected inside the storage barrel 21, and the gate cylinder 7 slides up and down to control the size of the effective discharge port of the long through hole 71, and a fixing plate 74 is fixedly connected to the top of the gate cylinder 7, and a movable groove 72 is opened on the side of the storage barrel 21, and the fixing plate 74 passes through the movable groove 72 and extends to the outside of the storage barrel 21, and the fixing plate 74 can slide up and down along the movable groove 72, and the top of the synchronous ring 22 is also rotatably connected with a vertical screw 73, which passes through the fixing plate 74 and is threadedly connected to the fixing plate 74, and the screw 73 is rotated, and the fixing plate 74 can drive the gate cylinder 7 to move up and down, so as to adjust the discharge speed of the additive, enhance the applicability, and can also be used for adding other additives.

[0041] like Figure 4As shown, a vibration component is provided between the umbrella-shaped plate 5 and the mixing kettle 1, and the vibration component includes an electromagnetic telescopic rod 6 and a collision ball 62. The electromagnetic telescopic rod 6 is horizontally fixed on the side of the umbrella-shaped plate 5. An elastic member 61 is also transversely provided on the inner wall of the mixing kettle 1. The collision ball 62 is fixed at one end of the elastic member 61 away from the mixing kettle 1. The collision ball 62 is horizontally aligned with the electromagnetic telescopic rod 6. The driving end of the collision ball 62 cooperates with the electromagnetic telescopic rod 6. Whether the elastic member 61 is extended or not controls whether the vibration component works. In a normal state, there is a certain distance between the electromagnetic telescopic rod 6 and the collision ball 62. When the umbrella-shaped plate 5 rotates, the electromagnetic telescopic rod 6 and the collision ball 62 do not collide. When the driving end of the electromagnetic telescopic rod 6 is extended, each rotation of the umbrella-shaped plate 5 can drive the electromagnetic telescopic rod 6 to collide with the collision ball 62 once, thereby generating vibration, so that the additive on the umbrella-shaped plate 5 is vibrated and dispersed and the feeding effect is improved.

[0042] like Figure 4 or Figure 7 As shown, a driving button 64 is also provided on the top of the synchronization ring 22, and the bottom of the fixed plate 74 cooperates with the driving button 64. In the initial state, the gate cylinder 7 is at a low position to block the long through hole 71. At this time, the bottom of the fixed plate 74 presses the driving button 64. When the gate cylinder 7 slides upward, the long through hole 71 starts to discharge material. At this time, the fixed plate 74 cancels the pressing of the driving button 64, and the electromagnetic telescopic rod 6 is electrically connected to the driving button 64. When the top of the driving button 64 is released from pressing, the electromagnetic telescopic rod 6 is driven to extend, that is, when discharging material, the vibration component starts to work.

[0043] like Figure 4 As shown, a rubber block 63 is provided between the mixing kettle 1 and the elastic member 61. By providing the rubber block 63, the elastic force of the elastic member 61 during vibration can be partially absorbed, thereby effectively reducing the vibration of the mixing kettle 1 and improving the performance of the mixing kettle 1.

[0044] Step 3: Use a coating machine to evenly coat the paste on the current collector to form the initial shape of the plate;

[0045] Step 4: Send the formed plates to the curing and drying equipment. When the temperature reaches above 80°C, the perborate additive begins to decompose, generating gas or volatile substances inside the plates, thereby forming pores.

[0046] Step 5: Use a microscope, porosity tester, etc. to detect the porosity of the plate to ensure that the porosity of the plate is increased by 8%-10%.

[0047] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
