Description

Technical Field

[0001] This utility model relates to the field of transducer technology, and in particular to ultrasonic vibrating screens and lithium battery production equipment. Background Technology

[0002] In the production process of lithium battery cathode materials, ultrasonic vibrating screens are often used to screen the materials. However, in the use of traditional ultrasonic vibrating screen systems, there is a possibility that the material accumulated on the screen may exceed its load-bearing limit, leading to screen breakage. Because the equipment itself vibrates during operation, it is difficult for operators to determine whether the transducers in the ultrasonic vibrating screen are working properly by visual observation or touch. By the time operators discover the abnormality, the material accumulated on the screen has already exceeded the safety limit, causing damage to the screen. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes an ultrasonic vibrating screen and lithium battery production equipment.

[0004] The solution to the technical problem of this utility model is: Firstly, an ultrasonic vibrating screen is proposed, comprising: A transducer includes a housing and a piezoelectric element, wherein the piezoelectric element is disposed inside the housing and connected to an external power source; A vibrating screen assembly includes a vibrating bar and a screen, one end of which is connected to the screen and the other end of which is connected to the output end of the transducer; A temperature measuring component includes a controller, a temperature measuring structure, and a display component. The temperature measuring structure is provided with a temperature measuring end, which is used to acquire the temperature of the outer shell. The temperature measuring structure and the display component are electrically connected to the controller, and the display component is used to display the temperature acquired by the temperature measuring structure.

[0005] This invention has at least the following beneficial effects: the piezoelectric element in the transducer uses the piezoelectric effect to convert electrical energy into mechanical vibration, which is then transmitted to the screen through the vibration bar to achieve material screening. The temperature measuring component measures the temperature of the transducer's outer shell without affecting the normal operation of the piezoelectric element. During the screening process, the temperature measuring component can measure the temperature of the transducer's outer shell. When the temperature of the transducer's outer shell is abnormal, the operator can judge the state of the transducer based on the temperature measurement data displayed on the display component and take corresponding measures to reduce the rate of sudden quality accidents and product quality accidents.

[0006] As a further improvement to the above technical solution, the temperature measuring structure is a contact temperature sensor, and the temperature measuring end of the contact temperature sensor is a conductive plate. The conductive plate is connected to the outer shell and electrically connected to the controller. The conductive plate is attached to the outer or inner side of the outer shell, and can directly sense the temperature of the outer shell.

[0007] As a further improvement to the above technical solution, the outer shell includes a body and a cover, with the piezoelectric element disposed between the body and the cover. The body is connected to the vibrating bar, and the conductive plate is connected to the inner wall surface of the cover. The output end of the transducer is located on one side of the body. By attaching the conductive plate to the cover, the vibration output of the transducer can be prevented from affecting the installation of the conductive plate, thus improving the temperature measurement accuracy of the conductive plate. Furthermore, by directly measuring the temperature of the inner wall of the cover through the conductive plate, the temperature measurement structure and the transducer can be integrated into a single unit.

[0008] As a further improvement to the above technical solution, the conductive plate is arranged around the outer periphery of the outer shell, and the temperature measuring component also includes a fixing clamp, which is arranged around the outer periphery of the conductive plate to fix the conductive plate and the outer shell. The conductive plate detects the outer wall temperature of the outer shell, and the fixing clamp ensures stable installation of the conductive plate, preventing it from falling off the outer wall of the outer shell. It also facilitates the installation and removal of the conductive plate from the transducer, making subsequent maintenance easier. Moreover, since the conductive plate wraps around the outer periphery of the transducer shell, it enables multi-angle temperature measurement of the transducer shell.

[0009] As a further improvement to the above technical solution, the temperature measuring component also includes a buffer strip, which is disposed between the fixing clamp and the conductive plate. By setting the buffer strip, the vibration of the transducer can be buffered, preventing the fixing clamp from becoming loose due to the vibration of the transducer.

[0010] As a further improvement to the above technical solution, the temperature measurement structure is a non-contact temperature sensor. The non-contact temperature sensor is located on the outside of the transducer, with its measuring end facing the outer shell. Using a non-contact temperature sensor as the temperature measurement structure enables temperature measurement of the transducer in scenarios where there is no need to add fixing clamps to the outer wall of the transducer or where replacing the existing transducer is not desired.

[0011] As a further improvement to the above technical solution, the temperature measuring component further includes a fixed frame, a rotating shaft, a rotating drive component, a first connecting rod, and a second connecting rod. The fixed frame extends vertically, the body of the rotating drive component is connected to the fixed frame, the rotating shaft is perpendicular to the fixed frame, one end of the rotating shaft is connected to the output end of the rotating drive component, the other end of the rotating shaft is hinged to one end of the first connecting rod, the other end of the first connecting rod is hinged to the second connecting rod, and the non-contact temperature sensor is connected to the second connecting rod. When the rotating drive component drives the rotating shaft to rotate, the rotating shaft drives the first connecting rod and the second connecting rod to rotate, so that the temperature measuring end of the non-contact temperature sensor rotates around the outer periphery of the housing.

[0012] Driven by the rotary drive component, the rotating shaft rotates, thereby driving the first link, the second link, and the non-contact temperature sensor to rotate, thus enabling multi-angle temperature measurement of the housing. Due to the hinge between the rotating shaft, the first link, and the second link, the relative position of the rotating shaft and the non-contact temperature sensor can be adjusted in real time according to the on-site working conditions to adapt to different on-site arrangements.

[0013] As a further improvement to the above technical solution, the temperature measuring component also includes an alarm, which is electrically connected to the controller. When the transducer temperature is abnormal, the controller can activate the alarm to sound an alarm, allowing operators to be notified promptly and take appropriate action.

[0014] As a further improvement to the above technical solution, the vibrating screen assembly also includes a screen frame and a support. One end of the support is connected to the screen frame, and the other end is connected to the transducer. The screen mesh and the vibrating bar are disposed inside the screen frame, and the output end of the transducer extends into the screen frame. Connecting the transducer and the screen frame with the support allows the transducer and the vibrating screen assembly of the ultrasonic vibrating screen to form a whole, which is more conducive to on-site installation.

[0015] Secondly, a lithium battery production equipment includes an ultrasonic vibrating screen as described in any of the above technical solutions. The ultrasonic vibrating screen can screen materials during the production of lithium battery cathode materials. Because the ultrasonic vibrating screen can monitor temperature to inform operators of any abnormalities, operators can promptly address any malfunctions to ensure screening efficiency.

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. The various technical features of this utility model can be combined interactively without contradicting each other.

[0024] Firstly, referring to Figures 1 to 4 This utility model embodiment proposes an ultrasonic vibrating screen that can be applied to the screening of materials 500, such as in the production process of lithium battery cathode materials. The ultrasonic vibrating screen of this embodiment can alert operators to abnormalities before the screen mesh 220 breaks, reducing losses caused by screen mesh 220 breakage.

[0025] In this embodiment, the ultrasonic vibrating screen includes a transducer 100, a vibrating screen assembly 200, and a temperature measuring assembly. The vibrating screen assembly 200 includes a vibrating bar 210 and a screen 220. One end of the vibrating bar 210 is connected to the screen 220, and the other end is connected to the output end of the transducer 100. After receiving a high-frequency electrical signal, the transducer 100 converts the high-frequency electrical signal into mechanical vibration of the same frequency. The vibration is transmitted to the screen 220 through the vibrating bar 210, thereby achieving vibration screening of the material 500 by the screen 220. The temperature measuring assembly includes a controller, a temperature measuring structure, and a display component. The temperature measuring structure has a temperature measuring end used to acquire the temperature of the transducer 100. The temperature measuring structure and the display component are electrically connected to the controller, and the display component is used to display the temperature acquired by the temperature measuring structure.

[0026] The transducer 100 can transmit vibrational potential energy to the screen 220 through the vibrating bar 210. If the vibrating bar 210 and the output end of the transducer 100 cannot be installed in close contact, according to the law of conservation of energy, when the potential energy cannot be released, and the drive of the transducer 100 still maintains electrical frequency output, the temperature of the transducer 100 will suddenly rise. If the energy efficiency of the transducer 100 itself decreases, the converted mechanical vibration will decrease, resulting in a decrease in the screening rate. Since the screening amount is a fixed amount of material, the material 500 on the screen 220 will accumulate more and more, which will affect the installation of the vibrating bar 210 and the output end of the transducer 100. The weight of the material 500 will cause the screen 220 to break and fail. At the moment the screen 220 fails, the temperature will also suddenly rise.

[0027] Therefore, by measuring the temperature of the transducer 100 through the temperature measuring structure, when an abnormal temperature is detected, the operator can promptly check the installation of the vibrating bar 210 and whether the screen 220 is accumulating material, so as to avoid the screen 220 breaking and failing, and reduce economic losses.

[0028] Understandably, when transducer 100 itself fails, the drive may display normally upon restarting, but there will be no mechanical vibration output. This fault occurs quite frequently in daily use. Since transducer 100 does not output potential energy, it does not have a normal operating temperature. The processing of new energy materials requires specific temperature and humidity conditions. The equipment is installed and operates in an environment with suitable temperature and humidity. The ambient temperature is generally lower than the normal operating temperature of transducer 100. The temperature sensing component can detect that transducer 100 does not heat up during a second startup, and this is clearly reflected on the display. This allows operators to easily understand the damage to transducer 100 and take timely action.

[0029] According to the on-site test data, the normal operating temperature of transducer 100 is 37-55℃, and the temperature will increase accordingly with the load; while the temperature of transducer 100 when it is not working is 20-23℃, and the temperature is affected by the ambient humidity.

[0030] In some embodiments, refer to Figure 2 The transducer 100 includes a housing and a piezoelectric element 130. The piezoelectric element 130 is disposed inside the housing and connected to an external power supply. A temperature measuring end is used to obtain the temperature of the housing. The working principle of the transducer 100 essentially utilizes the inverse piezoelectric effect of the piezoelectric material in the piezoelectric element 130 to convert electrical energy into high-frequency mechanical vibration and emit it. The transducer 100 transmits the vibrational potential energy to the screen 220 through the vibration bar 210, achieving efficient sieving. In this embodiment, the piezoelectric material is piezoelectric ceramic.

[0031] The temperature of the housing is measured by the temperature measuring component, which will not affect the use of the piezoelectric element 130 and avoid the temperature measuring component affecting the normal operation of the transducer 100.

[0032] This embodiment allows temperature measuring components to be installed inside, on, and outside the transducer 100, enabling applications in various scenarios and facilitating easy assembly.

[0033] In some embodiments, the temperature sensing structure is a contact temperature sensor, and the temperature sensing end of the contact temperature sensor is a conductive plate 300. The conductive plate 300 is connected to the housing and electrically connected to the controller. The conductive plate 300 is attached to the outer or inner side of the housing to directly sense the temperature of the housing and communicates with the controller using an analog signal transmission method.

[0034] In some embodiments, refer to Figure 2 The housing includes a body 120 and a cover 110. A piezoelectric element 130 is disposed between the body 120 and the cover 110. The body 120 is connected to the vibrating rod 210, and the cover 110 is connected to the conductive plate 300. The output end of the transducer 100 is located on one side of the body 120. By attaching the conductive plate 300 to the cover 110, the vibration output of the transducer 100 can be prevented from affecting the installation of the conductive plate 300, thereby improving the temperature measurement accuracy of the conductive plate 300.

[0035] In some embodiments, the conductive plate 300 is connected to the inner wall surface of the housing, allowing direct temperature measurement of the inner wall of the housing via the conductive plate 300, thus achieving integrated installation of the temperature measuring structure and the transducer 100. In this embodiment, the conductive plate 300 is installed on the inner side of the cover 110.

[0036] In some embodiments, the cover 110 is provided with an interface 150 for connecting the power supply to the transducer 100, and the conductive sheet 300 is connected with a wire 310, which is connected to the power supply through the interface 150.

[0037] In other embodiments, reference is made to Figure 3 The conductive plate 300 is arranged around the outer periphery of the housing, and the temperature measuring component also includes a fixing clamp 320, which is arranged around the outer periphery of the conductive plate 300. The conductive plate 300 and the housing can be fixed by the fixing clamp 320. Figure 3 The upper part of the central fixed clamp 320 is shown in perspective.

[0038] Understandably, the conductive plate 300 detects the temperature of the outer wall of the housing, and the fixing clamp 320 prevents the conductive plate 300 from detaching from the outer wall of the housing, ensuring stable installation. Furthermore, the fixing clamp 320 can be removed from the outside of the conductive plate 300, facilitating easy disassembly of the conductive plate 300 from the housing and aiding in subsequent maintenance. Additionally, because the conductive plate 300 surrounds the outer circumference of the housing, it enables multi-angle temperature measurement, resulting in more accurate temperature detection.

[0039] In some embodiments, the fixing clamp 320 is connected to the cover 110.

[0040] It is understandable that the fixing clamp 320 is provided with a cable passage, through which the cable for the electrical connection between the conductive plate 300 and the controller is passed.

[0041] In some embodiments, the temperature measuring assembly further includes a buffer strip 330, which is disposed between the fixing clamp 320 and the conductive plate 300 to reduce the impact of the transducer 100 vibration on the fixing clamp 320 and prevent the fixing clamp 320 from becoming loose due to the vibration of the transducer 100, so as to ensure the contact between the conductive plate 300 and the outer side of the housing and improve the temperature measurement accuracy.

[0042] Considering budget constraints, a temperature sensing component is added to the outside of the existing transducer 100. This component, using a conductive plate 300 attached to the cover 110, collects heat from the transducer 100's casing and transmits it to the controller via analog signal transmission. This setup eliminates the need for modifications to the transducer 100.

[0043] In other embodiments, reference is made to Figure 4 The temperature measurement structure is a non-contact temperature sensor, which is located on the outside of the transducer 100 with its measuring end facing the outer casing. Considering the requirements of certain installation scenarios, a non-contact temperature sensor is used to measure the temperature of the transducer 100 in real time.

[0044] In this embodiment, the non-contact temperature sensor is a laser infrared temperature sensor 340, which emits an infrared laser beam through a laser emitter and receives the laser signal reflected back from the surface of the transducer 100, converts it into a temperature value, and the controller controls the display component to display the real-time temperature.

[0045] Understandably, the laser infrared temperature sensor 340 can detect the temperature of the cover 110 or the body 120.

[0046] In some embodiments, the temperature measuring assembly further includes a fixed frame 350, a rotating shaft 360, a rotating drive component, a first connecting rod 370, and a second connecting rod 380. The fixed frame 350 extends vertically, the body of the rotating drive component is connected to the fixed frame 350, the rotating shaft 360 is perpendicular to the fixed frame 350, one end of the rotating shaft 360 is connected to the output end of the rotating drive component, the other end of the rotating shaft 360 is hinged to one end of the first connecting rod 370, the other end of the first connecting rod 370 is hinged to the second connecting rod 380, a non-contact temperature sensor is connected to the second connecting rod 380, and the temperature measuring end of the non-contact temperature sensor is positioned facing the housing of the transducer 100.

[0047] It is understandable that when the rotary drive component drives the rotary shaft 360 to rotate, the rotary shaft 360 can drive the first link 370 and the second link 380 to rotate, thereby causing the temperature measuring end of the non-contact temperature sensor to rotate around the outer periphery of the housing and perform multi-angle temperature measurement on the housing.

[0048] Understandably, due to the hinge between the rotating shaft 360, the first connecting rod 370, and the second connecting rod 380, the relative position of the rotating shaft 360 and the non-contact temperature sensor can be adjusted in real time according to the on-site working conditions to adapt to different on-site arrangements.

[0049] In some embodiments, the rotary drive component is a motor. For this type of temperature sensing component, the non-contact temperature sensor can communicate with the controller wirelessly, for example, via Bluetooth.

[0050] In some embodiments, the temperature sensing component also includes an alarm, which is electrically connected to the controller. When the temperature of the transducer 100 is abnormal, the controller can control the alarm to sound an alarm so that the operator can be informed in time and take corresponding actions.

[0051] It is understandable that abnormal temperature conditions include a sudden rise in temperature above the preset temperature, no temperature rise during the second startup of transducer 100, or a temperature rise less than the preset value.

[0052] Understandably, an alarm can be a buzzer, which sounds to alert the user; or it can be an indicator light, which emits different colors to alert the user.

[0053] The controller can be a microcontroller, a PLC controller, etc.

[0054] In some embodiments, refer to Figure 1 The temperature measuring component also includes a temperature measuring power supply, which is electrically connected to the temperature measuring structure and can supply power to the temperature measuring structure.

[0055] In some embodiments, the vibrating screen assembly 200 further includes a screen frame 230 and a support 240. One end of the support 240 is connected to the screen frame 230, and the other end is connected to the transducer 100. The screen mesh 220 and the vibrating bar 210 are disposed inside the screen frame 230. The output end of the transducer 100 extends into the screen frame 230 and is connected to the vibrating bar 210.

[0056] By connecting the transducer 100 and the screen frame 230 through the bracket 240, the transducer 100 and the vibrating screen assembly 200 of the ultrasonic vibrating screen can be integrated into a whole, which is more conducive to on-site installation.

[0057] In some embodiments, a transmission rod 140 is provided at the output end of the transducer 100, and the transmission rod 140 is connected to the wave rod 210 to realize energy transfer between the transducer 100 and the wave rod 210. During installation, a connection port 150 is provided at the end of the wave rod 210, and the transmission rod 140 extends into the screen frame 230 and is inserted into the connection port 150 of the wave function.

[0058] In some embodiments, the vibrating bar 210 includes a first connecting section and a second connecting section. During installation, the first connecting section is horizontally positioned, the lower end of the second connecting section is connected to the first connecting section and is inclined upward, and the upper end of the second connecting section is connected to the screen 220, which can provide support for the screen 220.

[0059] In some embodiments, the ultrasonic vibrating screen further includes a transducer power supply 400, which is connected to the transducer 100 via a line and is capable of providing high-frequency electrical signals to the transducer 100.

[0060] During use, material 500 is first placed on screen 220. After the transducer 100 is powered on, it converts high-frequency electrical signals into mechanical vibrations of the same frequency. These vibrations are transmitted to screen 220 via vibrating bar 210. Screen 220 vibrates and sieving the material 500, with larger pieces remaining above screen 220 and smaller pieces falling below. Throughout operation, the temperature measuring component measures the temperature of transducer 100 in real time and displays the temperature on the display unit. If a large amount of material 500 accumulates on screen 220, the output end of transducer 100 may not fit properly with vibrating bar 210, preventing the mechanical vibration energy from being released effectively and causing transducer 100 to overheat. Alternatively, if the power cord of transducer 100 has poor contact, the high-frequency electrical signal may be intermittently input to transducer 100, also causing abnormal heating. Operators can promptly detect abnormalities in the ultrasonic vibrating screen by monitoring the abnormal temperature displayed on the screen and take appropriate measures accordingly.

[0061] The ultrasonic vibrating screen in this embodiment can obtain temperature control data through the temperature sensing component, allowing operators to clearly determine whether the transducer 100 is in normal operating condition. Abnormal overheating of the transducer 100 can be used to infer its installation status. In actual use, historical data analysis can be used to develop real-time alarm and maintenance / replacement plans for the transducer 100 based on its historical operating temperature. Because abnormal faults can be detected promptly, the rate of sudden quality accidents and the scope of impact of product quality incidents can be reduced.

[0062] On the other hand, this utility model embodiment proposes a lithium battery production equipment, which includes the ultrasonic vibrating screen proposed in any one of the embodiments of the first aspect, which can screen the material 500 in the production of lithium battery cathode material, and can promptly handle the ultrasonic vibrating screen that is malfunctioning, so as to ensure screening efficiency.

[0063] It is understood that since the lithium battery production equipment uses the ultrasonic vibrating screen described above, it has at least all the beneficial effects brought about by the technical solution of the above embodiments, which will not be repeated here.
