Description

Technical Field

[0001] The utility model belongs to the field of vanadium battery manufacturing, and particularly relates to a vanadium battery ion membrane placement platform. Background Art

[0002] The full name of vanadium battery is all-vanadium redox flow battery (English full name: Vanadium Redox Battery, abbreviated as VRB), which is a redox battery with active substances in circulating liquid state. The battery stack of vanadium battery relies on dozens or even hundreds of middle frame plates, cover plates, carbon plates, and ion membranes connected together by pre-pressure. The electrolyte flows in the grooves of the middle frame plates and flows into the carbon plates to react and generate electric potential. The ion membrane is located between two adjacent middle frame plates. Before bonding the ion membrane to the middle frame plate, it is necessary to glue the sealing ring on the front and back sides of the ion membrane, and then bond it to the middle frame plate. The purpose of the sealing ring is to prevent the electrolyte flowing in the middle frame plate from flowing out of the groove and causing leakage. The electrolyte is expensive and is contaminated by heavy metals. Once it leaks, it will increase the subsequent maintenance costs and hazardous waste treatment costs, reduce the power generation efficiency of the system, pollute other components and the environment in the system, and reduce the service life of the battery stack.

[0003] The existing device for gluing ion membranes and sealing rings is to use a machine to clamp one of the sealing rings to a workbench, then apply or stick glue around the sealing ring, and then clamp the ion membrane to the sealing ring through a negative pressure clamp and other devices to combine the two. After the combination is completed, apply or stick glue around the ion membrane, and then clamp another sealing ring to the top of the ion membrane to complete the assembly of the ion membrane and the sealing ring. In the gluing device, the ion membrane and the sealing ring are both placed flat at different positions in the device. When clamping the ion membrane, because the ion membrane itself is easy to adhere together due to static electricity and other reasons, it is very easy to clamp two or three ion membranes at the same time when clamping. If the staff does not observe carefully, it will cause the adhesion of the ion membrane and the sealing ring to fail, requiring rework later, wasting time. If the staff does not find that there are multiple ion membranes between the two sealing rings after the gluing is completed, and directly enters the next step, it will cause the electrolyte ion exchange efficiency in the vanadium battery to decrease, affecting the overall working efficiency of the vanadium battery. Utility Model Content

[0004] The utility model aims to provide a vanadium battery ion membrane placement platform to solve the problem that the ion membrane is attached together due to static electricity and the like, resulting in the ion membrane and the sealing ring failing to adhere, thereby causing rework at a later stage or reducing the working efficiency of the vanadium battery.

[0005] A vanadium battery ion membrane placement platform in this scheme includes a placement table and multiple positioning blocks, wherein the multiple positioning blocks are fixedly connected to the two longer sides of the placement table, and the positioning blocks on both sides are symmetrically arranged, and the top ends of the multiple positioning blocks are laterally fixedly connected with brushes, and the multiple brushes all point to the center of the placement table.

[0006] The working principle and beneficial effects of this solution are as follows: when in use, multiple ion membranes are placed in the center of the platform, with the ion membranes located between the positioning blocks on both sides. Then, when assembling the ion membranes and the sealing rings, a negative pressure clamp or other mechanism is used to remove the ion membranes from above the placement table. The ion membranes will stick together due to static electricity and other reasons. After the clamp picks up the ion membranes, when passing through the brushes on both sides, the brushes can separate the ion membranes that are stuck together, and the ion membranes at the bottom will fall back to the placement table due to gravity. The device can separate the ion membranes that are stuck together before assembly, avoiding the ion membranes from sticking together due to static electricity and other reasons, resulting in failure in the assembly of the ion membranes and the sealing rings, reducing the later rework time, and enhancing the assembly efficiency of the vanadium battery.

[0007] Furthermore, a groove is provided in the center of the placing table, a lifting plate is provided in the groove, the top of the lifting plate is flush with the top of the placing table, and a lifting mechanism is provided on the side of the lifting plate close to the placing table to drive the lifting plate to rise and fall. When in use, multiple ion membranes can be placed in the middle of the lifting plate at one time. When the number of ion membranes is decreasing, the lifting mechanism can be turned on to drive the lifting plate and the ion membrane to rise together to a position close to the brush, so as to avoid the ion membrane from bending downward due to gravity due to the long rising distance during the rising process, so that the two sides of the ion membrane are away from the brush, thereby causing the brush to be unable to separate the adsorbed ion membranes, affecting subsequent installation.

[0008] Further, the lifting mechanism includes a lifting block and a positive and negative screw rod, a cavity is provided at the center of the groove of the placing table, the lifting mechanism is located in the cavity, the lifting block is fixedly connected to the bottom of the lifting plate, the positive and negative screw rod is horizontally placed in the cavity, one end of the positive and negative screw rod is rotatably connected to the side wall of the placing table cavity, one end of the positive and negative screw rod is fixedly connected to a motor driving it to rotate, the positive and negative screw rod is provided with two sections of threads with opposite rotation directions, both sections of the threads are threadedly connected to thread blocks, the ends of the two thread blocks close to the lifting plate are hinged to connecting rods, and the ends of the two connecting rods away from the thread blocks are hinged to the lifting block. When in use, the motor is started, and the motor drives the positive and negative screw rod to rotate, thereby driving the thread blocks connected to the two sections of the threads to move toward each other and approach each other, driving the connecting rod to deflect, thereby pushing the lifting block to drive the lifting plate to rise together, and driving the ion membrane to move upward.

[0009] Furthermore, infrared sensors are provided under the plurality of brushes, and the infrared sensors are connected to an external controller through electrical signals. The infrared sensors can sense the height of the ion membrane, and when the ion membrane is lower than the height sensed by the infrared sensors, feedback signals are given to the controller, and the controller sends signals to control the motor to rotate, so that the lifting plate drives the ion membrane to rise, and when the ion membrane reaches the sensing height of the infrared sensors, the infrared sensors feedback signals to the controller, and the lifting mechanism is controlled to stop lifting.

[0010] Furthermore, a sliding rod is provided in the cavity of the placement platform, and the sliding rod and the positive and negative screw rods are located in the same horizontal plane and are parallel to each other, and both ends of the sliding rod are fixedly connected to the side walls of the cavity of the placement platform, and the two threaded blocks are slidably connected to the sliding rod. The sliding rod makes the movement of the threaded block more stable, and prevents it from rotating due to the rotation of the positive and negative screw rods, causing the lifting mechanism to jam.

[0011] Furthermore, the positioning blocks are provided with four, and the four positioning blocks form a group of two, and are symmetrically arranged on the longer side of the placement table. The symmetrically arranged positioning blocks can make the brush evenly brush the two sides of the ion membrane to separate the ion membranes attached together. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following is further described in detail through specific implementation methods:

[0017] The reference numerals in the drawings of the specification include: a placement table 1, a positioning block 2, a lifting plate 3, a brush 4, a lifting block 5, a motor 6, a forward and reverse screw rod 7, a connecting rod 8, a threaded block 9, an infrared sensor 10, and a sliding rod 11.

[0018] The embodiment is basically as shown in the attached Figure 1 to Figure 4As shown: a vanadium battery ion membrane placement platform, including a placement table 1, a lifting plate 3, and four positioning blocks 2, the top of the placement table 1 is provided with a groove, the lifting plate 3 is placed in the groove, and the top of the lifting plate 3 is flush with the top of the placement table 1, the four positioning blocks 2 are grouped in pairs, and are respectively fixedly connected to the two longer sides of the placement table 1, and the two groups of positioning blocks 2 are symmetrically arranged, the lifting plate 3 is located between the four positioning blocks 2, the tops of the four positioning blocks 2 are fixedly connected with brushes 4, the bristles of the brushes 4 point to the center of the lifting plate 3, infrared sensors 10 are arranged below the four brushes 4, the four infrared sensors 10 are fixedly connected to the side walls of the positioning blocks 2, the four infrared sensors 10 are connected to a controller (such as a PLC controller) through electrical signals, a cavity is provided in the center of the groove of the placement table 1, a lifting mechanism is arranged in the cavity, the bottom of the lifting mechanism is fixedly connected to the bottom of the cavity, and the lifting end of the lifting mechanism is fixedly connected to the bottom of the lifting plate 3;

[0019] The lifting mechanism includes a lifting block 5 and a forward and reverse screw rod 7. The lifting block 5 is fixedly connected to the bottom of the lifting plate 3. The forward and reverse screw rod 7 is horizontally arranged in the cavity of the placement plate. One end of the forward and reverse screw rod 7 is rotatably connected to the side wall of the cavity of the placement plate. The other end of the forward and reverse screw rod 7 is fixedly connected to a motor 6. The motor 6 is fixedly connected to the side wall of the cavity of the placement plate. The forward and reverse screw rod 7 is provided with two sections of threads with opposite rotation directions. Both sections of threads are threadedly connected to thread blocks 9. The tops of the two thread blocks 9 are hinged with connecting rods 8. The ends of the two connecting rods 8 away from the thread blocks 9 are hinged to the lifting block 5. A sliding rod 11 is provided in the cavity. The sliding rod 11 and the forward and reverse screw rod 7 are located in the same horizontal plane, and the sliding rod 11 and the forward and reverse screw rod 7 are parallel to each other. Both ends of the sliding rod 11 are fixedly connected to the side walls of the cavity of the placement table 1. The two thread blocks 9 extend to the sliding rod 11 and are slidably connected to the sliding rod 11.

[0020] The specific implementation process is as follows: when in use, multiple ion membranes are placed at the center of the lifting plate 3. When the ion membrane and the sealing ring are assembled, the negative pressure clamp takes the ion membrane out of the ion membrane placement table 1. When passing through four symmetrically arranged brushes 4, the brushes 4 can be used to brush both sides of the ion membrane to separate the ion membranes attached together due to static electricity and other reasons, and the excess ion membranes fall back to the platform due to gravity. After the ion membrane is used to a certain extent and leaves the sensing range of the infrared sensor 10, the infrared sensor 10 feeds back a signal to the controller, and the controller can send a signal to control the motor 6 to rotate, drive the forward and reverse screws 7 to rotate, and make the threaded blocks 9 move towards each other to the center. When the two threaded blocks 9 move toward the center, the connecting rod 8 is driven to deviate, so that the lifting block 5 rises upward, driving the lifting plate 3 and the ion membrane to rise together, until the ion membrane is located at the sensing position of the infrared sensor 10, and then feedback signals are given to the controller, and the controller controls the motor 6 to stop rotating, so as to avoid excessive rise of the lifting plate 3 and collision with the brush 4, and the rising ion membrane shortens the distance from the clamping ion membrane to the brush 4, so as to avoid the ion membrane being affected by gravity, causing the two sides of the ion membrane to droop downward, away from the working range of the brush 4, so that the brush 4 cannot effectively separate the ion membranes that are stuck together.

It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
