Description

Technical Field

[0001] This utility model relates to the field of materials testing technology, and in particular to a cleaning device. Background Technology

[0002] For lithium-ion battery cathode materials (nano lithium iron phosphate), quality testing is required before they can be put into use to determine whether the material quality meets the requirements. Among these tests, the magnetic foreign matter test requires the material to be adsorbed and cleaned to obtain a sample for testing before the quality test can be carried out.

[0003] However, manual cleaning of materials makes it difficult to standardize sample cleaning, which has an adverse effect on the consistency of sample quality testing, makes data benchmarking difficult, and staff can only clean one sample at a time, resulting in low efficiency.

[0004] Therefore, there is an urgent need for a cleaning device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a cleaning device that can standardize sample cleaning and enable staff to clean multiple samples simultaneously.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0009] Clean the magnetic sphere, which is placed inside the beaker;

[0010] A traction magnet is slidably connected to the frame along a first direction. The traction magnet is located below the beaker and corresponds to the bottom of the beaker. The cleaning magnet and the traction magnet can attract each other. The first direction is a specific direction in the horizontal direction.

[0011] A drive unit, which is mounted on the frame and has its output end connected to the traction magnet, is configured to drive the traction magnet to reciprocate along the first direction.

[0012] In some embodiments, the cleaning device further includes a transmission assembly comprising an eccentric wheel and a connecting rod. The eccentric wheel is connected to the output end of the drive member, one end of the connecting rod is connected to the eccentric wheel, and the other end is connected to the traction magnet. The drive member is configured to drive the eccentric wheel to rotate, thereby causing the connecting rod to swing and the traction magnet to reciprocate along the first direction.

[0013] In some embodiments, the cleaning apparatus further includes a guide assembly comprising a slide rail and a slider slidably connected to each other, one of the slide rail and the slider being mounted on the frame and the other being mounted on the traction magnet, the slide rail extending along the first direction.

[0014] In some embodiments, the guide assembly further includes limiting members, which are mounted on the slide rail, and two limiting members are respectively disposed on both sides of the slider along the first direction.

[0015] In some embodiments, the cleaning device further includes an anti-slip component, which includes a cup holder. The cup holder is mounted on the frame and has an arc-shaped surface on the side near the beaker. The arc-shaped surface can fit against the outer wall of the beaker.

[0016] In some embodiments, the anti-slip assembly further includes a fastening bolt, and the cup holder has a threaded hole facing the circumferential sidewall of the beaker, and the fastening bolt is threadedly connected to the threaded hole.

[0017] In some embodiments, the cleaning device further includes an emergency stop button, which is mounted on the frame and communicatively connected to the drive unit.

[0018] In some embodiments, the cleaning device further includes a shock-absorbing assembly, which includes a mounting plate and an elastic element. The mounting plate is connected to the frame, and the elastic element is disposed at the connection point between the mounting plate and the frame.

[0021] The cleaning device provided by this utility model places a cleaning magnetic ball inside a beaker, and a traction magnetic ball is slidably connected to the frame along a first direction. The traction magnetic ball is located below the beaker and corresponds to the bottom of the beaker. When it is necessary to clean a battery positive electrode material sample, the driving component can drive the traction magnetic ball to move back and forth along the first direction, thereby attracting the cleaning magnetic ball to move back and forth in the beaker along the first direction, stirring the cleaning liquid and sample in the beaker to clean the sample. Because the driving component controls the moving speed and movement pattern of the traction magnetic ball to be constant along the first direction, the cleaning magnetic ball can stir the cleaning liquid and battery positive electrode material sample in the beaker at a constant moving speed and movement pattern, so that the sample cleaning is standardized. The staff can operate multiple cleaning devices at the same time to clean multiple samples simultaneously, improving the cleaning efficiency of battery positive electrode material samples.

[0036] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

[0038] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] like Figures 1 to 3 As shown, this utility model provides a cleaning device for cleaning a battery positive electrode material sample in a beaker 100. The cleaning device includes a frame 1, a cleaning magnet 2, a traction magnet 3, and a driving component 4. The beaker 100 is placed on the frame 1. The cleaning magnet 2 is placed inside the beaker 100. The traction magnet 3 is slidably connected to the frame 1 along a first direction, located below the beaker 100 and corresponding to the bottom of the beaker 100. The cleaning magnet 2 and the traction magnet 3 can attract each other. The first direction is a specific direction in the horizontal direction. The driving component 4 is mounted on the frame 1 and its output end is connected to the traction magnet 3. The driving component 4 is configured to drive the traction magnet 3 to reciprocate along the first direction.

[0041] It should be noted that the beaker 100 contains cleaning fluid, a battery positive electrode material sample, and a cleaning magnet 2. The cleaning magnet 2 is continuously stirred in the cleaning fluid, thereby rinsing and cleaning the battery positive electrode material sample.

[0042] The cleaning device provided in this embodiment places the cleaning magnet 2 inside the beaker 100, and the traction magnet 3 is slidably connected to the frame 1 along the first direction. The traction magnet 3 is located below the beaker 100 and corresponds to the bottom of the beaker 100. When it is necessary to clean the battery positive electrode material sample, the driving component 4 can drive the traction magnet 3 to move back and forth along the first direction, thereby attracting the cleaning magnet 2 to move back and forth in the beaker 100 along the first direction, stirring the cleaning liquid and sample in the beaker 100 to clean the sample. Because the driving component 4 controls the moving speed and movement pattern of the traction magnet 3 to be constant along the first direction, the cleaning magnet 2 can stir the cleaning liquid and battery positive electrode material sample in the beaker 100 at a constant moving speed and movement pattern, so that the sample cleaning is standardized. The staff can operate multiple cleaning devices at the same time to clean multiple samples at the same time, improving the cleaning efficiency of battery positive electrode material samples.

[0043] Continue as Figures 1 to 3As shown, the cleaning device also includes a transmission assembly 5, which includes an eccentric wheel 51 and a connecting rod 52. The eccentric wheel 51 is connected to the output end of the drive member 4, and one end of the connecting rod 52 is connected to the eccentric wheel 51, while the other end is connected to the traction magnet 3. The drive member 4 is configured to drive the eccentric wheel 51 to rotate, thereby causing the connecting rod 52 to swing and the traction magnet 3 to reciprocate along a first direction. Thus, the drive member 4 drives the traction magnet 3 to reciprocate along the first direction through the transmission assembly 5. This converts the rotational power output of the drive member 4 into the linear motion power of the traction magnet 3, changing the transmission direction and transmission type, thereby reducing the volume of the transmission mechanism required to achieve the reciprocating movement of the traction magnet 3 along the first direction, and thus reducing the overall volume of the cleaning device. Specifically, the drive member 4 is a rotary motor, and the output end of the rotary motor is connected to the eccentric wheel 51 to drive the eccentric wheel to rotate.

[0044] like Figure 3 As shown, the cleaning device also includes a guide assembly 6, which includes a slide rail 61 and a slider 62 that are slidably connected to each other. One of the slide rail 61 and the slider 62 is mounted on the frame 1, and the other is mounted on the traction magnet 3. The slide rail 61 extends along a first direction, thereby guiding the movement direction of the traction magnet 3 when cleaning the battery positive electrode material sample. This further unifies the movement speed and movement pattern of the traction magnet 3 when it moves along the first direction, thereby enabling the cleaning magnet 2 to stir the cleaning solution and the battery positive electrode material sample in the beaker 100 with a more constant movement speed and movement pattern, thus improving the standardization of sample cleaning.

[0045] Preferably, the guide assembly 6 further includes limiting members 63, which are installed on the slide rail 61. Two limiting members 63 are respectively disposed on both sides of the slider 62 along the first direction, thereby limiting the maximum movement range of the traction magnet 3 when it moves in the first direction, preventing the traction magnet 3 from moving too far and causing the slide rail 61 to disengage from the slider 62. Specifically, the limiting member 63 can be a hard limiting member, such as a limiting block, limiting strip, or damper, installed on the slide rail 61, capable of directly colliding with the slider 62 or the traction magnet 3 to obstruct its movement. Alternatively, the limiting member 63 can be a soft limiting member, such as a micro switch, photoelectric switch, or proximity switch. When the slider 62 or the traction magnet 3 triggers the detection element of the limiting member 63, the limiting member 63 can send a signal to the drive member 4, thereby stopping the drive member 4 from driving the traction magnet 3 to move.

[0046] like Figure 2 As shown, the cleaning device also includes an anti-slip component 7, which includes a cup holder 71. The cup holder 71 is installed on the frame 1 and has an arc-shaped surface on the side near the beaker 100. The arc-shaped surface fits against the outer wall of the beaker 100, so that when the cleaning magnet 2 moves back and forth in the first direction inside the beaker 100, the beaker 100 is prevented from shaking and falling off the frame 1.

[0047] Preferably, the anti-slip component 7 also includes a fastening bolt 72. The cup holder 71 has a threaded hole facing the peripheral wall of the beaker 100. The fastening bolt is threadedly connected to the threaded hole, so that the fastening bolt 72 can be screwed on and pressed against the peripheral wall of the beaker 100 to prevent the beaker 100 from shaking when cleaning the sample.

[0048] like Figure 1 As shown, the cleaning device also includes an emergency stop button 8, which is mounted on the frame 1 and communicates with the drive unit 4. In case of an accident during the cleaning process of the cleaning device for battery positive electrode material samples, the operator can press the emergency stop button 8 in time to stop the cleaning device from operating.

[0049] Continue as Figure 1 As shown, the cleaning device also includes a shock-absorbing component 9, which includes a mounting plate 91 and an elastic element 92. The mounting plate 91 is connected to the frame 1, and the elastic element 92 is disposed at the connection position between the mounting plate 91 and the frame 1. This allows the vibration caused by the reciprocating movement of the cleaning magnet 2 in the beaker 100 along the first direction to be transmitted through the mounting plate 91 to the elastic element 92, enabling the elastic element 92 to absorb the vibration and prevent it from being transmitted to the frame 1. Specifically, the elastic element 92 can be a rubber pad, a sponge pad, or a nylon pad. Any elastic material capable of absorbing vibration is within the scope of this embodiment and will not be described in detail here.

[0050] Continue as Figure 1 As shown, the frame 1 includes a tray 11, a beaker 100 is placed on the tray 11, and a traction magnet 3 is located below the tray 11, thereby preventing the traction magnet 3 from touching the beaker 100 and causing the beaker 100 to break during the reciprocating movement along the first direction.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
