Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of secondary batteries, and in particular relates to ultrasonic spraying equipment. Background Art
[0002] Solid-state batteries are becoming the main development direction for next-generation batteries because their safety and energy density are far superior to existing liquid batteries. Solid-state batteries refer to batteries that use solid electrolytes, while liquid batteries refer to batteries that use liquid electrolytes.
[0003] For solid-state batteries, the introduction of solid-state electrolytes largely determines the working performance of solid-state batteries, including cycle stability, safety, etc. In related technologies, ultrasonic spraying is used to achieve solid-state electrolyte introduction, that is, the solid electrolyte is sprayed onto the surface of the electrode by ultrasonic spraying. Although ultrasonic spraying can obtain a uniform solid electrolyte layer on the surface of the electrode, when the ultrasonic spray gun stops spraying, the material in the pipeline is in a static state and will precipitate until it is separated into upper and lower layers. When the material is separated into layers in the pipeline, if the ultrasonic spray gun is turned on again to continue spraying, the separated materials will enter the pipeline and be sprayed out of the nozzle, resulting in white spots or stripes on the electrode, which affects the spraying quality of the solid electrolyte layer.

It should also be understood that the term "and / or" as used herein refers to and encompasses any or all possible combinations of one or more of the associated listed items.
[0027] like Figure 1 、 Figure 2 As shown, an ultrasonic spraying device provided by an embodiment of the present utility model includes: a material storage part 1, a first reversing valve 2, a metering unit 4, a second reversing valve 3 and an ultrasonic spray head 5.
[0028] The first reversing valve 2 is connected to the material storage member 1 , the metering unit 4 and the second reversing valve 3 respectively.
[0029] For example, but not limited to, the first reversing valve 2 and the second reversing valve 3 may both be two-position three-way reversing valves, preferably two-position three-way electromagnetic reversing valves.
[0030] Correspondingly, the first reversing valve 2 and the second reversing valve 3 can both have three connection ports, the first connection port 21 of the first reversing valve 2 is connected to the material storage part 1 through a pipeline, the second connection port 22 of the first reversing valve 2 is connected to the metering unit 4 through a pipeline, the third connection port 23 of the first reversing valve 2 is connected to the first connection port 31 of the second reversing valve 3 through a pipeline, the second connection port 322 of the second reversing valve 3 is connected to the ultrasonic nozzle 5 through a pipeline, and the third connection port 33 of the second reversing valve 3 is connected to the material storage part 1 through a pipeline; that is, the second reversing valve 3 is also connected to the ultrasonic nozzle 5 and the material storage part 1.
[0031] The pipeline referred to herein may include at least any one of a pipe, a pipe joint, and a hole for conveying a fluid.
[0032] The first reversing valve 2 has a first working position and a second working position. In the first working position state, that is, when the first connecting port 21 of the first reversing valve 2 is connected to the second connecting port 22, the metering unit 4 is used to extract material 12 from the material storage part 1. In the second working position state, that is, when the second connecting port 22 of the first reversing valve 2 is connected to the third connecting port 23, the metering unit 4 is used to deliver the extracted material 12 to the second reversing valve 3.
[0033] The metering unit 4 can accurately extract a predetermined amount of material 12 from the storage part 1, and then transport it to the ultrasonic nozzle 5 through the second reversing valve 3 described below and spray it onto the target object (such as an electrode, etc.) to ensure the accuracy of the spraying and form a dense and uniform coating on the surface of the target object.
[0034] The material 12 mentioned here can be a slurry for forming a solid electrolyte layer. In other examples, it can also be a positive electrode slurry, a negative electrode slurry, etc.
[0035] The second reversing valve 3 has a third position and a fourth position. In the third position state, that is, when the first connecting port 31 and the second connecting port 32 of the second reversing valve 3 are connected, the material 12 is transported to the ultrasonic nozzle 5 through the second reversing valve 3. In the fourth position state, that is, when the second connecting port 32 and the third connecting port 33 of the second reversing valve 3 are connected, the material 12 is transported to the material storage part 1 through the second reversing valve 3.
[0036] The above scheme, by setting the second reversing valve 3, can switch the second reversing valve 3 to the fourth position when the ultrasonic nozzle 5 stops spraying, so that the material 12 in the pipeline is transported to the material storage part 1 through the second reversing valve 3, avoiding the material 12 from being stationary in the pipeline, and thus avoiding the problem of the material 12 settling and forming upper and lower stratification due to the stationary state. When the ultrasonic nozzle 5 continues to spray, the second reversing valve 3 is switched to the third position, and the material 12 is transported to the ultrasonic nozzle 5 through the second reversing valve 3. Since the material 12 does not have the problem of settling in the pipeline and forming upper and lower stratification, the problem of reduced spraying quality due to the precipitation of the material 12 is avoided.
[0037] As an achievable method, see at least Figure 2As shown, the ultrasonic nozzle 5 includes a first ultrasonic transducer, a discharge channel 55 and a blowing channel 54. The first ultrasonic transducer includes a first ultrasonic vibration rod 51. The discharge port 551 of the discharge channel 55 and the blowing port 541 of the blowing channel 54 are respectively arranged on both sides of the first ultrasonic vibration rod 51. The discharge port 551 is used to provide the material 12 to the first ultrasonic vibration rod 51, and the blowing port 541 is used to blow air to the first ultrasonic vibration rod 51.
[0038] The vibration frequency of the first ultrasonic vibration rod 51 can be as high as 400,000 times / min. Of course, the vibration frequency here is only an example and can also be other frequency values. The first ultrasonic vibration rod 51 is used to break up the material 12 flowing out of the discharge port 551. The air blowing port 541 blows compressed gas toward the first ultrasonic vibration rod 51 to blow the broken material 12 into a fan shape. The size of the fan shape can be controlled by controlling the air pressure of the compressed gas blown out of the air blowing port 541 and the distance between the ultrasonic nozzle 5 and the target object, thereby achieving the purpose of controlling the spraying range and shape.
[0039] Specifically, the ultrasonic nozzle 5 is fixed on the spraying bracket 52, the spraying bracket 52 is arranged vertically, and a fixing ring 53 is arranged below the spraying bracket 52. The first ultrasonic vibration rod 51 passes through the center hole 531 of the fixing ring 53, and the diameter of the center hole 531 is larger than the diameter of the first ultrasonic vibration rod 51, so that the first ultrasonic vibration rod 51 and the center hole 531 are loosely matched.
[0040] A liquid outlet nozzle serving as a discharge channel 55 is fixedly connected to the fixed ring 53 . The liquid outlet nozzle is provided with the aforementioned discharge port 551 . The discharge port 551 is located below the fixed ring 53 and faces the first ultrasonic vibration rod 51 .
[0041] The fixing ring 53 is also fixedly connected to an air blowing pipe serving as an air blowing channel 54 . One end of the air blowing pipe is the air blowing port 541 . The air blowing port 541 is also located below the fixing ring 53 and faces the first ultrasonic vibration rod 51 .
[0042] As an implementable manner, the blowing direction of the blowing port 541 is arranged to be inclined with respect to the axis of the first ultrasonic vibration rod 51 .
[0043] For example, the above-mentioned blowing tube is a straight tube, and the axis of the straight tube is tilted relative to the axis of the first ultrasonic vibration rod 51, so that its blowing direction is tilted to the axis of the first ultrasonic vibration rod 51. By setting the blowing direction to be tilted to the axis of the first ultrasonic vibration rod 51, the material 12 broken up by the first ultrasonic vibration rod 51 can be blown into a fan shape, and the fan-shaped material 12 can be evenly sprayed onto the target object to form a uniform coating.
[0044] As an implementable manner, the diameter of the discharge port 551 is 0.8 mm-1.2 mm, and the distance D1 between the discharge port 551 and the first ultrasonic vibration rod 51 in a direction perpendicular to the axis of the first ultrasonic vibration rod 51 is 0.8 mm-1.5 mm.
[0045] The above-mentioned size can ensure that the material 12 is continuously and stably transported to the first ultrasonic vibration rod 51. On the one hand, it can avoid the problem of material 12 dripping due to excessive distance and discontinuous spraying; on the other hand, it can also avoid the problem of material 12 not being fully broken up due to excessive distance, resulting in reduced coating uniformity.
[0046] As an implementation method, in a direction perpendicular to the axis of the first ultrasonic vibration rod 51, the distance between the blowing port 541 and the first ultrasonic vibration rod 51 is greater than the distance between the discharge port 551 and the first ultrasonic vibration rod 51, and the distance D2 between the blowing port 541 and the first ultrasonic vibration rod 51 is 1mm-5mm.
[0047] By adopting the above-mentioned size, the material 12 dispersed by the first ultrasonic vibration rod 51 can be blown into a uniform fan shape, so that the material 12 can be evenly sprayed onto the target object to form a dense and uniform coating.
[0048] As an implementable method, the metering unit 4 includes a metering container 411, the metering container 411 includes a circular cavity, a piston 417 is slidably arranged in the circular cavity, one end of the piston 417 is fixedly connected to the piston rod 413, and the other end is movably provided with a stirring member 416, a hole is provided in the piston rod 413 along the axis of the piston rod 413, a rotating rod 414 is rotatably connected in the hole, a driving motor 415 is provided at the end of the rotating rod 414 away from the piston 417, a first ferromagnetic member is provided at the end of the rotating rod 414 close to the piston 417, the stirring member 416 includes a second ferromagnetic member, and at least either of the first ferromagnetic member and the second ferromagnetic member is a magnet.
[0049] The material 12 is quantitatively sucked in and discharged by moving the piston 417. In order to prevent the material 12 from settling in the circular cavity and causing adverse effects on spraying, a stirring member 416 is provided in the circular cavity. When the material 12 is in the circular cavity, the driving motor 415 drives the rotating rod 414 to rotate. The rotating rod 414 then drives the stirring member 416 to rotate through magnetism to stir the material 12 in the circular cavity, thereby preventing the material 12 from settling in the circular cavity.
[0050] By placing the stirring member 416 and the rotating rod 414 at both ends of the piston 417, it is not necessary to make a hole in the piston 417 for the rotating rod 414 to pass through. This can avoid the problem of dynamic sealing at the hole position and prevent the material 12 from leaking from the hole position. On the basis of not requiring a hole to achieve the rotation of the stirring member 416 by the rotating rod 414, a first ferromagnetic member is provided at the end of the rotating rod 414 near the piston 417, and the stirring member 416 includes a second ferromagnetic member. At least one of the first ferromagnetic member and the second ferromagnetic member is a magnet. Through the magnetic attraction between the first ferromagnetic member and the second ferromagnetic member, when the rotating rod 414 rotates, the stirring member 416 can be driven to rotate.
[0051] Preferably, the first ferromagnetic part and the second ferromagnetic part are both magnets to increase the magnetic force and avoid the problem that the stirring part 416 cannot rotate due to the attraction between the first ferromagnetic part and the second ferromagnetic part being unable to overcome the rotational resistance of the stirring part 416 due to the magnetic force being too small.
[0052] As an implementation manner, a Teflon layer is provided on the outer side of the second ferromagnetic member, the Teflon layer is in contact with the side surface of the circular cavity, and the rotation axis of the stirring member 416 is coaxially arranged with the axis of the circular cavity.
[0053] In order to reduce the rotational resistance of the stirring member 416 and prevent the stirring member 416 from damaging the circular cavity during rotation, a Teflon layer is provided on the outer side of the second ferromagnetic member. The Teflon material has a self-lubricating effect and can reduce the rotational resistance of the stirring member 416. In addition, the Teflon layer is in contact with the side of the circular cavity, which can prevent the stirring member 416 from shaking left and right during rotation and causing damage to the side of the circular cavity.
[0054] As an implementable method, the metering unit 4 also includes a first support member 412 and a second support member 422 that slide with each other, and the sliding direction is parallel to the axis of the piston rod 413. A linear drive is arranged between the first support member 412 and the second support member 422, and the linear drive is used to drive the first support member 412 and the second support member 422 to slide relative to each other. The metering container 411 is fixedly connected to the first support member 412, and the second support member 422 includes a first connecting portion 418 and a second connecting portion 419 that are spaced apart, and the second connecting portion 419 and the piston 417 are respectively arranged on both sides of the first connecting portion 418, and the end of the piston rod 413 facing away from the piston 417 is fixedly connected to the first connecting portion 418, and the drive motor 415 is fixedly connected to the second connecting portion 419.
[0055] In this example, the first support member 412 is a fixed component, and the second support member 422 is slidably engaged with the first support member 412 along a direction parallel to the axis of the piston rod 413. Of course, in other examples, the second support member 422 may be a fixed component, and the first support member 412 is slidably engaged with the second support member 422 along a direction parallel to the axis of the piston rod 413.
[0056] In order to make the first support member 412 and the second support member 422 slide more smoothly, a slider 421 can be set on one of the first support member 412 and the second support member 422, and a slide rail 423 can be set on the other, and a sliding guide is provided by the sliding cooperation between the slider 421 and the slide rail 423.
[0057] The linear actuator can be a pneumatic cylinder, an electric push rod, a hydraulic cylinder, a screw mechanism, etc. In this example, a screw mechanism is used, which includes a screw rod, a motor connected to the screw rod, and a motor fixed to the first support member 412. A nut is threaded onto the screw rod, and the nut rotates in conjunction with the second support member 422. The rotation of the motor drives the screw rod to rotate, and the rotation of the screw rod drives the nut to move horizontally along the axis of the piston rod 413. The nut drives the second support member 422 to slide on the first support member 412 along the axis of the piston rod 413 in synchronization with the second support member 422.
[0058] The motor may be a stepper motor 420 , and the amount of suction and discharge of the material 12 may be precisely controlled by precisely controlling the rotation angle of the stepper motor 420 .
[0059] As an achievable method, the material storage member 1 includes a tank body 11, the tank body 11 includes a circular side wall 101, the lower part of the circular side wall 101 is provided with an inverted frustum-shaped bottom wall 102, the inverted frustum-shaped bottom wall 102 is provided with a discharge port 15, the upper part of the circular side wall 101 is provided with a top wall 14, the top wall 14 is provided with a stirring motor 132, the stirring motor 132 is connected to a stirring rod 131, and the stirring rod 131 extends into the tank body 11.
[0060] By providing the stirring rod 131 , the stirring motor 132 can be used to drive the stirring rod 131 to stir the material 12 in the material storage part 1 to prevent precipitation.
[0061] The tank body 11 includes a circular side wall 101. When the stirring rod 131 stirs the material 12 in the tank body 11, the material 12 is not blocked in the circumferential direction, which can avoid the problem of precipitation of the material 12 in the blocked area due to local obstruction, and is conducive to improving the uniformity of mixing of the material 12 in the tank body 11.
[0062] The lower portion of the tank body 11 is configured as an inverted truncated cone bottom wall 102 , which facilitates the remaining material 12 to be gathered in the inverted truncated cone bottom wall 102 and discharged through the discharge port 15 after spraying is completed.
[0063] As an implementation, see also Figure 3 As shown, at least one second ultrasonic transducer 16 is provided on the top wall 14, and the second ultrasonic transducer 16 includes a second ultrasonic vibration rod 162, which extends into the tank body. The second ultrasonic vibration rod 162 includes a plurality of first diameter rod segments 1621 and second diameter rod segments 1622 that are alternately arranged in sequence, and the diameter of the first diameter rod segment is different from the diameter of the second diameter rod segment 1622.
[0064] By providing the second ultrasonic transducer 16 , the uniformity of mixing of the material 12 in the tank body 11 can be improved, and precipitation of the material 12 can be further prevented.
[0065] The second ultrasonic vibration rod 162 includes a first diameter rod segment 1621 and a second diameter rod segment 1622 of different diameters that are alternately arranged in sequence, which can increase the irregularity of the disturbance and diffuse the material 12 in multiple directions to improve the uniformity of the mixing of the material 12.
