Description

Technical Field

[0001] The utility model relates to the technical field of solid vanadium batteries, and more specifically to a solid vanadium battery preparation device. Background Art

[0002] Solid vanadium batteries are a new type of battery chemistry developed based on vanadium redox flow batteries. Their electrolyte is solid, composed of a highly active vanadium compound uniformly mixed with a conductive agent, binder, and dispersant. The highly active vanadium compound is adsorbed into the micropores of the high-specific-surface-area conductive and dispersant agents. High-energy solid-state vanadium batteries tightly compact the active electrolyte and current collector to form the positive and negative electrodes, separated by a separator to facilitate sealing and securing the components. Compared with vanadium redox flow batteries, vanadium ions in solid vanadium batteries are no longer restricted by the requirement of stable dissolution in solvents. The concentration and content of vanadium are increased by at least 80%. At the same time, there is no need for transportation systems and storage tanks similar to those required for traditional liquid flow vanadium batteries. This reduces the volume of the battery by more than 2 times, thereby essentially improving the energy density of the battery. In the preparation process of solid vanadium batteries, the conveyor is a key part of the entire device. The solid vanadium battery preparation device is closely connected to the conveyor and cooperates with each other. The conveyor provides a basic platform for the transportation of battery components. It can transport the battery components placed on it to the appropriate location to ensure that the components can enter the next process according to the predetermined process.

[0003] If the existing conveyors cannot be adjusted according to the battery components, they will not be able to accurately position battery components of different sizes. During transportation, the battery components are prone to position displacement and shaking, resulting in reduced product quality in subsequent processing steps. Conveyors that cannot be adjusted have poor versatility and can only adapt to battery components of specific sizes. When different models of solid vanadium batteries need to be prepared and the component size changes, the conveyors may not be able to be used. This means that companies may need to equip battery components of different sizes with a variety of different specifications of conveyors, which increases equipment investment costs and equipment floor space, and the equipment utilization rate is not high, which is not conducive to the company's efficient production and cost control.

[0004] The utility model can make the preparation process of the solid vanadium battery more flexible and convenient. Utility Model Content

[0015] Beneficial effects:

[0016] 1. By setting a limit plate and utilizing its precise positioning function, the spacing of solid vanadium battery components of different sizes can be flexibly adjusted, effectively preventing the components from shifting and shaking on the conveyor, laying the foundation for subsequent stable processing; by coordinating with components such as the positioning plate, thread groove and screw, the operator can conveniently operate the screw to lift and slide by rotating the hand-tightening disk, easily changing the position of the limit plate, and quickly adapting to various component specifications, greatly improving production efficiency and equipment versatility.

[0025] The following is a combination of the appended examples of the present invention Figure 1-Figure 5 , clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0026] See also Figure 1-5 In an embodiment of the utility model, a solid vanadium battery preparation device includes: a conveyor 1, an auxiliary platform 2 is provided on one side of the conveyor 1, two limit plates 3 are provided on the upper end of the conveyor 1, a hydraulic rod 4 is provided on one side of one limit plate 3, a guide plate 5 is provided between the conveyor 1 and the auxiliary platform 2, and baffles 6 are provided on both sides of the auxiliary platform 2; a plurality of threaded grooves 101 are provided on the upper ends of both sides of the conveyor 1, a push plate 401 is installed on the output end of the hydraulic rod 4, two positioning plates 301 are fixedly installed on the outer sides of the two limit plates 3, and grooves 201 are provided on both sides of the upper end of the auxiliary platform 2.

[0027] During the preparation of solid vanadium batteries, the battery assembly is first placed on the conveyor 1. The position of the positioning plate 301 in the upper threaded groove 101 on both sides of the conveyor 1 is adjusted to determine the distance between the two limit plates 3 to accommodate battery assemblies of different sizes. The hydraulic rod 4 is started, and the push plate 401 at the output end of the hydraulic rod 4 pushes to prevent the battery assembly from deviating from its position, making the battery assembly more stable when moving on the conveyor 1. When the battery assembly moves to the guide plate 5 between the conveyor 1 and the auxiliary table 2, due to the guiding effect of the guide plate 5, the battery assembly slides smoothly onto the auxiliary table 2. The baffles 6 on both sides of the auxiliary table 2 can prevent the battery assembly from falling from both sides of the auxiliary table 2 during the sliding process. At this time, the battery assembly can be further processed on the auxiliary table 2, such as connecting and installing the electrodes. The outer shell and other operations can be carried out by cooperating with the threaded groove 101 and the positioning plate 301, so as to accurately adjust the distance between the limit plates 3, thereby realizing precise positioning of solid vanadium battery components of different sizes, ensuring that the battery components will not shift or shake during transportation, and stable transmission helps to improve the accuracy and consistency of subsequent processing procedures, reduce processing errors caused by unstable component positions, and improve product quality. The device can adapt to solid vanadium battery components of different sizes by simply adjusting the position of the limit plate 3, and has strong production flexibility. When facing the production needs of various types of solid vanadium batteries, there is no need to replace the entire set of equipment, only appropriate adjustments are needed to put it into use, which reduces the equipment investment cost, improves the equipment utilization rate and production adaptability, and makes the device more flexible in use.

[0028] In the embodiment of the present utility model, a sliding groove 302 is formed at the upper end of the positioning plate 301, and the sliding groove 302 passes through the bottom of the positioning plate 301. A screw 303 is embedded in the sliding groove 302, and the sliding groove 302 and the screw 303 are in sliding connection. The bottom of the screw 303 can be embedded in the thread groove 101, and a hand-tightening disk 304 is fixedly installed on the upper end of the screw 303. The screw 303 and the thread groove 101 are detachably connected.

[0029] When the distance between the two limit plates 3 needs to be adjusted to accommodate solid vanadium battery components of different sizes, the operator can rotate the hand-tightening disk 304 to drive the screw 303 to rotate. Since the bottom of the screw 303 can be embedded in the thread groove 101 at the upper end of both sides of the conveyor 1 and form a detachable connection therewith, and the screw 303 is embedded in the slide groove 302 at the upper end of the positioning plate 301 and is slidably connected to the slide groove 302, when the hand-tightening disk 304 is rotated, the screw 303 will move up or down in the thread groove 101. At the same time, it slides along the slide groove 302, thereby driving the positioning plate 301 to move along the length direction of the conveyor 1, thereby changing the distance between the two limit plates 3. When it is adjusted to the appropriate position, stop rotating the hand-tightening disk 304, and the bottom of the screw 303 is stably embedded in the thread groove 101, so that the limit plate 3 remains fixed, providing accurate positioning for the battery assembly. The combined design of the hand-tightening disk 304, screw 303, slide groove 302 and thread groove 101 allows the operator to easily and conveniently adjust the distance between the limit plates 3 without the need for Complex tools or professional skills are not required. Only the manual rotation of the hand-tightening disk 304 is required to achieve precise adaptation and positioning of solid vanadium battery components of different sizes. This convenience can quickly switch the processing of different models of products during the production process, greatly improving production efficiency, reducing the time and labor costs consumed by adjusting equipment, and making the production process smoother and more efficient. The detachable connection between the screw 303 and the thread groove 101 and the sliding fit of the screw 303 in the slide groove 302 ensure the stability of the position of the positioning plate 301 while achieving flexible adjustment. Once adjusted into place, the screw 303 is firmly embedded in the thread groove 101, further limiting the battery component, making the device more stable when transporting the battery component. This structural design facilitates maintenance and inspection of the equipment. If the screw 303, positioning plate 301 and other components are worn or malfunction, the screw 303 can be easily removed from the thread groove 101 for repair or replacement. At the same time, the device can adapt to battery components of various sizes through simple adjustment, thereby improving the versatility of the equipment.

[0030] In the embodiment of the present utility model, a rotating shaft 501 is provided on one side of the guide plate 5, and both ends of the rotating shaft 501 are installed on the inner side of one end of the conveyor 1, and the rotating shaft 501 and the guide plate 5 are rotatably connected; one side of the guide plate 5 is conical, and the bottom of the lower end of the guide plate 5 contacts the upper end of the auxiliary platform 2. The guide plate 5 is inclined, and a spring 502 is provided at the bottom of the guide plate 5, and the bottom of the spring 502 contacts the auxiliary platform 2; a connecting block 503 is provided at the bottom of the spring 502, and a ball 504 is embedded in the connecting block 503 and the bottom of one side of the guide plate 5, and the ball 504 contacts the upper end of the auxiliary platform 2;

[0031] When the battery assembly is pushed to the guide plate 5 by the push plate 401 on the conveyor 1, since one side of the guide plate 5 is conical and tilted, the battery assembly will slide along the inclined surface of the guide plate 5 to the auxiliary table 2. In this process, the guide plate 5 is rotatably connected to the inner side of one end of the conveyor 1 through the rotating shaft 501, and can adaptively adjust the angle according to the sliding situation of the battery assembly to better guide the battery assembly to slide smoothly. At the same time, the spring 502 at the bottom of the guide plate 5 plays a buffering role. When the battery assembly slides onto the guide plate 5, the spring 502 will be compressed to absorb part of the impact force to prevent the battery assembly from being damaged due to collision. The connecting block 503 at the bottom of the spring 502 and the ball 504 embedded in the bottom of one side of the guide plate 5 are in contact with the upper end of the auxiliary table 2. When the auxiliary table 2 is replaced with a machine with a transport structure, the guide plate 5 is moved on the auxiliary table through the ball 504 2, will not affect the use of the auxiliary table 2 and the guide plate 5, making the sliding of the battery assembly smoother and more stable. The special shape of the guide plate 5, the rotating connection method, and the design of the ball 504 and the spring 502 together ensure the smooth transfer of the battery assembly from the conveyor 1 to the auxiliary table 2, reduce friction and collision during the transfer process, reduce the risk of damage to the battery assembly, improve the efficiency and success rate of material transfer, and protect the battery assembly and equipment: the buffering effect of the spring 502 effectively protects the battery assembly from excessive impact force, prevents the internal structure or external shell of the battery from being damaged due to collision, and improves the product yield. At the same time, the setting of the ball 504 reduces the wear between the guide plate 5 and the auxiliary table 2, extends the service life of the equipment, reduces the equipment maintenance cost, and further improves the stability and reliability of the production process.

[0032] In the embodiment of the present utility model, a contact plate 601 is provided on the inner side of the baffle 6, and a number of anti-collision strips 602 are provided on the inner side of the contact plate 601. The inner side of the anti-collision strip 602 is arc-shaped, and the interior of the anti-collision strip 602 is a hollow structure. A protrusion 604 is provided on the inner side of the anti-collision strip 602, and a card slot 605 is provided on one side of the contact plate 601. The protrusion 604 can be embedded in the interior of the card slot 605, and the protrusion 604 and the card slot 605 are connected; a card block 603 is provided at the bottom of the baffle 6, and the card block 603 is embedded in the interior of the groove 201, and the card block 603 and the groove 201 are movably connected.

[0033] When the battery assembly slides from the conveyor 1 to the auxiliary platform 2, it may collide with the baffle 6 due to inertia or other reasons. At this time, the contact plate 601 and the anti-collision strip 602 on the inside of the baffle 6 play a role. The arc shape of the inner side of the anti-collision strip 602 can better fit the outer contour of the battery assembly. Since its interior is a hollow structure and has a certain elasticity, it can effectively buffer the impact force during a collision. When the anti-collision strip 602 is squeezed, it further disperses and absorbs the collision energy to prevent the battery assembly from being damaged by a violent collision. The special structural design of the anti-collision strip 602, including the arc shape, hollow structure and the cooperation between the protrusion 604 and the slot 605, greatly enhances the protection of the battery assembly. During the transfer of the battery assembly, even if an accidental collision occurs, the impact force can be minimized, effectively avoiding scratches on the surface of the battery assembly, damage to the internal structure and other problems, thereby improving The qualified rate and quality stability of the products reduce the cost waste caused by product damage and ensure the production efficiency of solid vanadium batteries. The movable connection between the bottom block 603 of the baffle 6 and the groove 201 and the buffering of the collision force by the anti-collision strip 602 reduce the stress on the baffle 6 when it is collided with the battery component, which helps to reduce the risk of deformation and damage of the baffle 6 due to long-term stress, extend the service life of the baffle 6 and the entire auxiliary table 2 device, reduce the frequency of equipment maintenance and replacement, reduce equipment maintenance costs, improve the reliability and durability of production equipment, and are conducive to the long-term and stable production operation of the enterprise. Reliable battery component protection and equipment stability guarantee make the entire solid vanadium battery preparation process smoother and more orderly, reduce the number of production interruptions due to equipment failure or product damage, and improve production continuity and stability.

[0034] Working principle: In the initial state of the device, the operator adjusts the spacing of the limit plates 3 according to the size specifications of the solid vanadium battery components to be transported, and rotates the hand-tightening disk 304, which drives the screw 303 to rotate. Since the bottom of the screw 303 can be embedded in the threaded groove 101 at the upper ends of both sides of the conveyor 1 and form a detachable connection therewith, the screw 303 is embedded in the slide groove 302 at the upper end of the positioning plate 301 and is slidably connected to the slide groove 302. Under the action of the rotational force, the screw 303 will rise or fall in the threaded groove 101, and the screw 303 slides along the slide groove 302, thereby changing the spacing between the two limit plates 3. When it is adjusted to a suitable position that matches the size of the battery component, Stop rotating the hand-tightening disk 304. At this time, the bottom of the screw 303 is stably embedded in the threaded groove 101, so that the limit plate 3 remains fixed, thereby providing accurate positioning for the battery assembly. The battery assembly is placed on the conveyor 1 with the limit plate 3 spacing adjusted, and the hydraulic rod 4 is started. The hydraulic rod 4 further limits the battery assembly. Due to the limiting effect of the two limit plates 3, the battery assembly will not deviate from its position during the movement and can move forward stably along the predetermined track. When the battery assembly is moved to the guide plate 5 between the conveyor 1 and the auxiliary platform 2 under the push of the push plate 401, since one side of the guide plate 5 is conical and tilted, the battery assembly will begin to slide along the inclined surface of the guide plate 5. When the battery assembly slides When the battery pack falls onto the guide plate 5, the spring 502 will be compressed to absorb part of the impact force, thereby preventing the battery pack from being damaged due to collision. The connecting block 503 at the bottom of the spring 502 and the ball 504 embedded at the bottom of one side of the guide plate 5 are in contact with the upper end of the auxiliary table 2. When the auxiliary table 2 is an ordinary platform, the ball 504 can reduce the friction between the guide plate 5 and the auxiliary table 2, making the battery pack slide more smoothly and steadily; when the auxiliary table 2 is replaced with a machine with a transport structure, the guide plate 5 rotates on the upper end of the auxiliary table 2 through the ball 504, which will not affect the normal use of the auxiliary table 2 and the guide plate 5, ensuring that the battery pack can smoothly transition from the conveyor 1 to the auxiliary table 2. When the battery pack slides onto the auxiliary table 2, the auxiliary table 2 The baffles 6 on both sides of the auxiliary platform 2 can prevent the battery assembly from falling from both sides of the auxiliary platform 2 during the sliding process. If the battery assembly collides with the baffle 6 due to inertia or other reasons, the contact plate 601 and the anti-collision strip 602 on the inside of the baffle 6 begin to play a role. The arc shape on the inside of the anti-collision strip 602 can better fit the outer contour of the battery assembly. Since its interior is a hollow structure and has a certain elasticity, it can effectively buffer the impact force during a collision, further disperse and absorb the collision energy, and prevent the battery assembly from being damaged due to severe collision. The block 603 at the bottom of the baffle 6 is embedded in the grooves 201 on both sides of the upper end of the auxiliary platform 2 and is movably connected, making it easier to replace the anti-collision strip 602 after wear, further improving the flexibility of the device.
