DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there can be a central component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time.

[0042] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this application and in the specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this application includes any and all combinations of one or more of the related listed items.

[0043] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0044] This application provides a ball mill 100, please refer to Figure 1 , used to drive the ball mill to rotate, the ball mill includes a tank body and a cover body. The tank body and the cover body can be detachably connected, and the inside of the ball mill is used to accommodate the material to be processed and the ball mill beads.

[0045] In one embodiment, the ball mill 100 is a fully automatic ball mill 100, including an automatic rotation mechanism and an automatic pressing mechanism, wherein the automatic rotation mechanism is used to drive the ball mill to rotate, and the automatic pressing mechanism is used to clamp or press the body and cover of the ball mill.

[0046] Optionally, there may be multiple ball mills, and the automatic rotation mechanism drives the multiple ball mills to revolve around a central axis, and can also drive each ball mill to rotate while revolving. Preferably, the cover and the tank body can be opened and closed in the same direction of the central axis, and the automatic rotation mechanism drives the tank body to drive the cover body to rotate.

[0047] Preferably, the number of the ball milling jars is four, that is, there are at least four positions for placing the ball milling jars on the ball mill 100. In addition, the four ball milling jars are arranged in an annular manner with equal spacing. It is understood that the number of the ball milling jars can be increased or decreased according to actual needs, such as 3, 5, 6, 8 or other numbers.

[0048] In one implementation, please refer to Figure 2 The automatic clamping mechanism includes a supporting assembly, a first driving member 21 and a clamping assembly. The first driving member 21 and the clamping assembly are installed on the supporting assembly. The first driving member 21 is connected to the clamping assembly. The first driving member 21 is used to drive the clamping assembly to clamp or loosen the cover body; the automatic rotating mechanism includes a second driving member 5 and a rotating assembly. The second driving member 5 is transmission-connected to the rotating assembly. The rotating assembly is connected to the supporting assembly. The ball mill is placed on the rotating assembly. The second driving member 5 is used to drive the rotating assembly to rotate to drive the ball mill and the supporting assembly to rotate.

[0049] The present application provides a ball mill that can be used for ball milling of sample materials in automated experiments for functional material synthesis. The device is provided with an automatic clamping mechanism, and uses a first driving member 21 to drive a clamping assembly to clamp the cover of the ball mill jar, so that the cover and the jar body can be tightly combined. This process can be completed by the first driving member 21. The clamping action reduces manual labor and improves the degree of automation of the closure of the ball mill jar, so that the device can meet the needs of high-throughput experiments and introduce an automated system; at the same time, the device is also provided with an automatic rotation mechanism, and uses a second driving member 5 to drive the ball mill jar and the automatic clamping mechanism to rotate synchronously through a rotating assembly, so that the automatic clamping mechanism can keep the cover pressed while the ball mill is performing ball milling, and prevent the cover from detaching from the jar body when the ball mill is operating at high speed.

[0050] In one implementation, please refer to Figure 2 The support assembly is connected to the automatic rotating mechanism, and the first driving member 21 and the pressing assembly are both mounted on the support assembly. The automatic rotating mechanism is also used to drive the support assembly to follow the movement of the ball mill.

[0051] Optionally, the first driving member 21 may be a motor, and the type of the motor is not limited. Preferably, the first driving member 21 is a through-axis linear stepping motor.

[0052] For further information, please refer to Figure 3 The clamping assembly includes a fixed part 29A and a movable part 27A. The fixed part 29A is rotatably connected to the movable part 27A, and the fixed part 29A is connected to the first driving part 21; the first driving part 21 is used to drive the fixed part 29A to move so that the movable part 27A presses or loosens the cover body. During the rotation of the ball mill, the movable part 27A rotates with the cover body and rotates relative to the fixed part 29A.

[0053] Optionally, the fixing member 29A can be connected to the output shaft of the first driving member 21, and the first driving member 21 can drive the fixing member 29A to move toward or away from the cover of the ball mill. Optionally, the first driving member 21 can simultaneously drive the fixing member 29A and the movable member 27A to move toward or away from the cover of the ball mill. Preferably, the first driving member 21 and the clamping assembly are located directly above the ball mill. When the ball mill revolves, the first driving member 21, the fixing member 29A and the movable member 27A revolve together with the ball mill; when the ball mill rotates, at least part of the structure of the movable member 27A rotates together with the ball mill. It can be understood that when the ball mill only revolves, the clamping assembly can be driven to be pressed against the cover and revolve together with the cover, and at this time, there is no need to set the movable member to rotate.

[0054] Optionally, the output shaft of the first driving member 21 is parallel to the above-mentioned central axis, and the first driving member 21 can drive the fixing member 29A to move along the axis direction of the output shaft. It can be understood that the first driving member 21 drives the fixing member 29A to move along the axis direction of the output shaft to connect the movable member 27A and the cover body until the cover body and the tank body are pressed tightly, thereby ensuring that the cover body and the tank body are sealed, and can remain sealed even during the rotation or revolution of the ball mill tank.

[0055] Optionally, the movable member 27A is connected to the cover body, and during the rotation of the cover body, at least part of the movable member 27A can rotate with the cover body and can rotate relative to the fixed member 29A. In this way, during the rotation of the ball mill jar, there will be no rotational interference between the ball mill jar and the first driving member 21.

[0056] Optionally, the number of the first driving members 21 and the pressing assemblies is the same as the number of the ball milling jars. That is, based on the above embodiment, the number of the first driving members 21 and the pressing assemblies are both four, and each corresponds to a ball milling jar, so as to press the corresponding cover.

[0057] Optionally, the movable member 27A can be connected and fixed to the cover body. It needs to be explained that the movable member 27A and the cover body can actually be a detachable connection, but after the ball mill 100 is assembled, the movable member 27A can always remain connected to the cover body. In this way, the first driving member 21 can drive the movable member 27A and the cover body to move together through the fixing member 29A, that is, the cover body and the tank body are driven to separate after ball milling, and the cover body and the tank body are driven to combine after loading. In addition, when the cover body needs to be cleaned or replaced, the cover body can be removed from the movable member 27A. It can be understood that this process (i.e., opening and closing the cover) is completely performed by the first driving member 21, and no manual operation is required. Preferably, in order to adapt to different types of ball mills, there is no fixed connection between the movable member 27A and the cover body, and the movable member 27A moves toward the cover body under the drive of the first driving member 21, and abuts against the cover body to press the cover body and the tank body.

[0058] The present application provides a ball mill 100, which can be used for the ball milling of sample materials in the automated experiment of functional material synthesis. The device is provided with a clamping assembly, and the clamping assembly includes a fixed part 29A and a movable part 27A that are rotatably connected. The fixed part 29A is connected and driven to move by the first driving part 21, so that the fixed part 29A can press the cover of the ball mill jar through the movable part 27A, so that the cover and the jar can be tightly combined. This process can be completed by the first driving part 21. The clamping action reduces manual labor and improves the automation of the closing of the ball mill jar, so that the device can meet the needs of high-throughput experiments and introduce an automated system; at the same time, during the rotation of the ball mill jar, the movable part 27A can follow the cover to rotate relative to the fixed part 29A, and the cover and the jar can be kept airtight during this process. After the ball milling is completed, the fixed part 29A is driven away by the first driving part 21, and the operation of loosening the cover and the jar is completed in time.

[0059] In one implementation, please refer to Figure 3 The fixed member 29A has a round ball head 29A1 at one end close to the movable member 27A, and the movable member 27A has an inner cavity 27A1 with a curved surface, and the round ball head 29A1 is accommodated in the inner cavity 27A1 and can rotate in the inner cavity 27A1. The movable member 27A is detachably connected or abutted with the cover body. Specifically, as shown in the figure, the fixed member 29A may include a connecting portion and a round ball head 29A1, wherein the connecting portion is connected and fixed to the output shaft of the first driving member 21, and the round ball head 29A1 is connected to the end of the connecting portion away from the output shaft.

[0060] Optionally, the movable member 27A includes two opposite ends, wherein the end facing away from the cover body is provided with an inner cavity 27A1 having a curved surface. The inner cavity 27A1 has an opening communicating with the external space, and the round ball head 29A1 extends into the inner cavity 27A1 through the opening. It can be understood that since the round ball head 29A1 is spherical and is accommodated in the inner cavity 27A1 having a curved surface, it has a degree of freedom; therefore, the round ball head 29A1 and the movable member 27A are movably connected, and when the cover body drives the movable member 27A to rotate, the round ball head 29A1 can remain stationary in the inner cavity 27A1.

[0061] Preferably, the outline of the inner cavity 27A1 can be spherical.

[0062] Optionally, the opening of the inner cavity 27A1 is circular, and the diameter of the opening is smaller than the diameter of the circular ball head 29A1.

[0063] Optionally, the material of the round ball head 29A1 is a polymer material, and the material of the movable part 27A is also a polymer material. This reduces interference during friction. Optionally, the round ball head 29A1 and the movable part 27A can both be made of metal materials, such as stainless steel, aluminum alloy, etc.; the round ball head 29A1 can be made of metal, and the movable part 27A can be made of polymer material, such as rubber.

[0064] Optionally, one end of the movable part 27A connected to the cover body may be a suction cup structure, that is, it is adsorbed on the cover body through vacuum negative pressure, or it may be a snap-on, magnetic or other structure.

[0065] By cooperating with the circular ball head 29A1 of the fixed part 29A and the inner cavity 27A1 of the movable part 27A, relative rotation can be achieved between the fixed part 29A and the movable part 27A. In addition, the structure is simple, easy to manufacture, and convenient to repair and replace, which can greatly save the manufacturing and maintenance costs of the ball mill 100.

[0066] In one implementation, please refer to Figure 2 and Figure 4 The movable member 27A includes a first bearing 27, the first bearing sleeve 27 is arranged on the outer periphery of the fixed member 29A, and the inner ring of the first bearing 27 is connected and fixed to the fixed member 29A, and the outer ring of the first bearing 27 can rotate relative to the fixed member 29A.

[0067] like Figure 4 As shown, the fixing member 29A can be a fixing shaft 29. The fixing shaft 29 is connected and fixed to the output shaft of the first driving member 21; the first bearing 27 is sleeved on the outer periphery of the fixing shaft 29, and the inner ring of the first bearing 27 is connected and fixed to the fixing shaft 29, and the outer ring of the first bearing 27 is used to connect to the cover body.

[0068] Specifically, two opposite ends of the fixed shaft 29 are connected to the output shaft of the first driving member 21 and the first bearing 27 respectively.

[0069] Optionally, the first bearing 27 can be an angular contact bearing, which includes an inner ring and an outer ring, and the inner ring and the outer ring can rotate relative to each other. It can be understood that the structure of the first bearing 27 can be annular, so the first bearing 27 can be sleeved on the outer periphery of the fixed shaft 29.

[0070] The advantage of using an angular contact bearing for the first bearing 27 is that it can bear radial force and axial force at the same time and can work at a higher speed. The larger the contact angle, the higher the axial load capacity.

[0071] Optionally, the first driving member 21 can independently drive the fixed shaft 29 to move up and down (in the axial direction), and the first bearing 27 can be fixedly connected to the cover body.

[0072] Preferably, the first driving member 21 drives the fixed shaft 29 and the first bearing 27 to move up and down (in the axial direction) at the same time.

[0073] Optionally, a cavity for accommodating the first bearing 27 may be formed on the cover, and the contour of the cavity matches the outer contour of the first bearing 27. Therefore, the first bearing 27 can be limited to rotate only inside the cavity and cannot move radially, thereby ensuring the reliability of the equipment during the ball milling process.

[0074] By setting the movable part 27A as the first bearing 27 and the fixed part 29A as the fixed shaft 29, the relative rotation between the fixed shaft 29 and the cover body can be achieved through the coordinated rotation of the inner and outer rings of the first bearing 27. The first bearing 27 can have a smoother rotation, reduce interference during the rotation of the ball mill, and can also adapt to the higher rotation speed of the ball mill.

[0075] In one implementation, please refer to Figure 2 and Figure 4 The movable part 27A also includes a bearing sleeve 26 and a first retaining ring 28, wherein the bearing sleeve 26 encloses the accommodating cavity 26A and has an opening, the first bearing 27 extends into the accommodating cavity 26A from the opening, the outer ring of the first bearing 27 is connected to the inner wall of the accommodating cavity 26A, the bearing sleeve 26 is used to press the cover body and rotate with the cover body when the ball mill rotates; the first retaining ring 28 is arranged at the opening and connected to the bearing sleeve 26 to limit the axial movement of the first bearing 27.

[0076] Specifically, the bearing sleeve 26 is a hollow structure, and its outer peripheral contour shape can be cylindrical, so as to adapt to the first bearing 27. The opening is located on the top surface (or bottom surface) of the cylinder. The first bearing 27 extends into the accommodating cavity 26A from the opening, and the outer ring of the first bearing 27 is connected to the inner wall of the accommodating cavity 26A. The bearing sleeve 26 moves toward the cover body under the drive of the first driving member 21, and abuts against the cover body, so that the cover body and the tank body are pressed tightly.

[0077] Optionally, based on the above embodiment, the bearing sleeve 26 can be accommodated in a cavity on the cover body, so that when the cover body rotates, the bearing sleeve 26 and the outer ring of the first bearing 27 can be driven to rotate accordingly.

[0078] Furthermore, the first retaining ring 28 may be an annular plate member, which is sleeved on the outer circumference of the fixed shaft 29 and located at the opening of the bearing sleeve 26 to close the opening.

[0079] Optionally, the inner wall of the accommodating cavity 26A has an annular groove for engaging with the first retaining ring 28, thereby being more conducive to restricting the first bearing 27 in the accommodating cavity 26A.

[0080] Optionally, when the bearing sleeve 26 rotates, the first retaining ring 28 may remain stationary, or rotate accordingly with the bearing sleeve 26 .

[0081] Therefore, when the lower end of the output shaft of the first driving member 21 (the end close to the ball mill) is connected and fixed to the fixed shaft 29, the first bearing 27 assembled on the fixed shaft 29 is fixed by the first retaining ring 28. In addition, the bearing pressing sleeve 26 forms a pressure head that can rotate around the axis of the fixed shaft 29 under the cooperation of the outer ring of the first bearing 27, and the pressure head cooperates with the self-rotation of the ball mill when pressing the cover body.

[0082] By arranging a bearing sleeve 26 on the first bearing 27, not only can the outer ring of the first bearing 27 be matched to realize rotation, but also the first bearing 27 can be protected and the wear of the first bearing 27 can be reduced; and the bearing sleeve 26 can have more material options (such as metal, plastic, rubber, etc.). Compared with directly connecting the cover body with the first bearing 27, the friction between the bearing sleeve 26 and the cover body can be increased by adjusting the material; further, the first retaining ring 28 can be arranged to cooperate with the bearing sleeve 26 to fix the first bearing 27, so as to avoid up and down movement (axially) during the movement of the bearing.

[0083] In one embodiment, the outer surface of the bearing sleeve 26 and the side facing away from the first bearing 27 can be a suction cup structure. In combination with the above embodiment, the bearing sleeve 26 is adsorbed on the cover body by vacuum negative pressure. The advantage of suction cup adsorption is that more covers can be adapted, and there is no need to make a structure adapted to the bearing sleeve 26 on the cover body, which increases the universality of the ball mill 100 provided by the present application.

[0084] In one implementation, please refer to Figure 2 , Figure 5 and Figure 6 The support assembly includes a support seat 19, a clamp bottom plate 20, a clamp top plate 32 and a guide column 23. The support seat 19 is fixedly connected to the rotating assembly, the clamp bottom plate 20 includes a first surface and a second surface opposite to each other, the first driving member 21 is installed on the first surface, and the output shaft of the first driving member 21 passes through the first surface to the second surface and is connected to the clamping assembly, and the second surface is connected to an end of the support seat 19 away from the rotating assembly; the clamp top plate 32 includes a third surface facing the first surface, and the clamp top plate 32 and the clamp bottom plate 20 are spaced apart; the two opposite ends of the guide column 23 are respectively connected to the first surface and the third surface, and are spaced apart from the output shaft of the first driving member 21.

[0085] Specifically, the fixture bottom plate 20 is a plate-like structure, including a first surface and a second surface facing each other. The first surface faces away from the ball mill and the automatic rotating mechanism (the second surface faces the ball mill and the automatic rotating mechanism). The first driving member 21 is fixedly mounted on the first surface, and the output shaft of the first driving member 21 can pass through the fixture bottom plate 20 to extend to the ball mill. Therefore, the clamping assembly can also be located between the second surface and the ball mill.

[0086] Optionally, the fixture bottom plate 20 is a circular plate. The plurality of first driving members 21 are arranged in a circular array with the center of the fixture bottom plate 20 in a uniform arrangement.

[0087] The fixture top plate 32 is a plate-shaped structure, including a third surface facing the first surface. The first driving member 21 is located between the fixture bottom plate 20 and the fixture top plate 32 .

[0088] Optionally, the fixture top plate 32 is a circular plate, and the fixture top plate 32 and the fixture bottom plate 20 may have the same shape and size.

[0089] The guide post 23 extends along the axial direction of the output shaft of the first driving member 21, and its two opposite ends are respectively connected to the clamp bottom plate 20 and the clamp top plate 32. It can be understood that the guide post 23 is used to support the clamp top plate 32 and connect the clamp top plate 32 with the clamp bottom plate 20.

The first connecting end 31A is slidably connected to the guide column 23, and the second connecting end 31B is fixed on the output shaft of the first driving member 21, and the second connecting end 31B is connected to the end of the output shaft of the first driving member 21 away from the clamping assembly.

[0092] Specifically, the guide seat 31 can be a collar with two holes. The two holes are respectively located on the first connection end 31A and the second connection end 31B. The hole on the first connection end 31A is used for the guide column 23 to pass through, and the hole on the second connection end 31B is used for the output shaft of the first driving member 21 to pass through. Optionally, the output shaft of the first driving member 21 can pass through the second connection end 31B or not, and there is no specific limitation.

[0093] It can be understood that the guide seat 31 and the guide column 23 should be slidably connected, and the guide seat 31 should be fixedly connected to the output shaft of the first driving member 21. When the first driving member 21 drives the output shaft to move up and down (in the axial direction), one end of the output shaft is fixedly connected to the guide seat 31 and drives the guide seat 31 to move up and down (in the axial direction). Through the first connecting end 31A, the guide seat 31 can move along the axial direction of the guide column 23 without being easily deviated.

[0094] By setting the guide seat 31, the guide seat 31 and the guide column 23 can be used to cooperate to achieve the guided movement of the output shaft of the first driving member 21, reduce the deviation of the first driving member 21 in the process of driving the output shaft, and ensure the stability of the structure and the reliability of the automatic clamping process. Optionally, a guide column 23 is set next to each first driving member 21, that is, the first driving member 21 corresponds to the guide column 23 for guidance. Alternatively, two first driving members 21 share a guide column 23 for guidance.

The linear bearing 24 moves up and down along the guide column 23 to drive the guide seat 31 to move up and down. Therefore, after the upper end (the end away from the clamping assembly) of the output shaft of the first driving member 21 is connected to the guide seat 31, the output shaft can move up and down through the linear bearing 24 and the guide column 23.

[0096] In one implementation, please refer to Figure 2 and Figure 6 The ball mill 100 further includes a first rotating shaft 25, a second bearing 35, a bearing seat 34 and a fixed plate 36.

With the above design, the fixed plate 36 can play a stabilizing role, and when the automatic clamping mechanism rotates with the ball mill, the stability of the entire structure can be ensured; and the automatic clamping mechanism will not cause the center to shift due to rapid rotation.

[0097] Specifically, a through hole may be provided at the center of the clamp top plate 32, so that at least part of the first rotating shaft 25 may pass through the through hole. In addition, the first rotating shaft 25 may be fixedly connected to the clamp top plate 32, and when the support assembly rotates, the clamp top plate 32 may drive the first rotating shaft 25 to rotate accordingly.

The diameter of the shoulder can be larger than the diameter of the column, so as to ensure that the shoulder does not pass through the through hole on the clamp top plate 32, and can also have a larger area to contact the third surface. The fixing parts (screws) can connect the clamp top plate 32 and the shoulder along the axial direction of the column, thereby providing a more reliable connection method.

[0099] The second bearing 35 is sleeved on the outer circumference of the first rotating shaft 25 that passes through the fixture top plate 32. The second bearing 35 may include an inner ring and an outer ring that are rotatably connected (the structure may refer to the first bearing 27); wherein the inner ring of the second bearing 35 is fixedly connected to the first rotating shaft 25.

[0101] Optionally, the fixing plate 36 and the bearing seat 34 are fixedly connected, and the fixing plate 36 can be fixedly connected to other structures; for example, a gantry, a wall, etc., without limitation. It can be understood that the fixing plate 36 is used to provide a fixing point to fix the bearing seat 34 so that the inner and outer rings of the second bearing 35 can rotate relative to each other.

[0102] Optionally, the fixing plate 36 is mounted on the side of the bearing seat 34 facing away from the fixture top plate 32, and the surface where the fixing plate 36 and the bearing seat 34 are connected can be connected by screws.

[0106] Optionally, the first rotating shaft 25 may be provided with a through hole along the axial direction, and a cable adapter may be provided at one end close to the conductive slip ring 39. The cable adapter is used to connect the conductive slip ring 39 and the cables of the first driving member 21 (such as power cables, signal cables, etc.). These cables may be passed through the through hole to ensure that the cables of the first driving member 21 will not get entangled when rotating with the supporting assembly, thereby ensuring stable operation of the structure.

It can be understood that the tensioning plate 3 drives the second driving member 5 away from or close to the second rotating shaft 13 (that is, the first synchronous wheel 4 is away from or close to the second synchronous wheel 9) by adjusting the supporting plate 2, so that the synchronous belt 6 can be tightened or loosened.

[0149] In one embodiment, the ball mill 100 further includes a driver and an encoder, which are electrically connected to the second driving member 5. The driver and the encoder can read and control the rotation angle position of the output shaft of the second driving member 5, thereby achieving the function of automatically positioning the ball mill jar.

[0150] Optionally, the driver in this embodiment and the controller 30 in the above embodiment may be the same component or different components, without specific limitation.

[0151] In one implementation, the present application also provides an operating method of an automatic clamping mechanism.

[0152] Optionally, after the loading is completed, the user can issue a clamping instruction via an external smart device, and then the controller 30 controls the first driving member 21 to drive the clamping assembly to press the cover body, so that the cover body and the tank body are pressed and sealed.

[0153] Optionally, after the ball milling is completed, the controller 30 can control the first driving member 21 to drive the clamping assembly away from the cover body, and detect the position of the second sensor sheet through the second sensor, so as to adapt the output shaft to move to a suitable position. After the experimental work is completed (i.e., no ball milling is required), the ball milling jar can be removed.

[0154] Optionally, the controller 30 can control the pressing force of the clamping assembly. It is understandable that the pressing force of the clamping assembly is actually the distance that the first driving member 21 drives its displacement (the interference displacement of the clamping assembly is a greater pressing force). Therefore, the controller 30 can control the displacement distance that the first driving member 21 drives the clamping assembly.

[0155] It is understandable that this method can be applied during ball milling and after the experimental work is completed. In addition, the pressing force during ball milling can be greater. This is because during ball milling, the ball mill jar rotates at high speed, and under the influence of centrifugal force, a greater pressing force is required to avoid the phenomenon of loose lid; after the experimental work is completed, the lid is closed to protect the inside of the tank body, and the tank body remains stationary without excessive pressure, thereby reducing the loss of the automatic rotating component that supports the tank body.

[0156] In one implementation, please refer to Fig.10 The ball mill 100 further includes a protective cover 33, wherein the protective cover 33 is sleeved on the outer periphery of the automatic pressing mechanism, and the protective cover 33 is used to protect the automatic pressing mechanism.

[0157] The present application also provides an experimental device, which includes an experimental platform and the aforementioned ball mill 100, and the ball mill 100 is arranged on the experimental platform.

[0158] In one implementation, please refer to Fig.10 The experimental equipment also includes a frame assembly 41, which is arranged below the experimental platform and is used to carry the experimental platform and the ball mill 100. An electric control device can be placed in the frame assembly 41 to supply power to the ball mill 100 and control the operation of the ball mill 100; for example, the driver and encoder mentioned above can be placed in the frame assembly 41.

[0159] In one implementation, please refer to Fig.10The experimental equipment also includes an outer cover 42, which encloses a storage space with the experimental platform, and the ball mill 100 is located in the storage space; a protective door is provided on the outer cover 42, and the ball mill 100 can interact with the outside world after the protective door is opened. The outer cover 42 can protect the ball mill 100. Among them, at least one side of the protective door and / or the outer cover 42 is provided with a visual window, that is, made of a transparent or translucent material, so that the experimenter can intuitively view the working status of the ball mill 100.

[0160] In one embodiment, the experimental equipment further includes a transfer device, which is used to take and place the ball mill jars to the ball mill 100. Optionally, the transfer device can be a mobile robot or a manipulator fixed on the experimental platform. The transfer device is used to grab the ball mill jars to be ball milled onto the placement tube 18, and / or take the ball mill jars after ball milling from the placement tube 18. Combined with the transfer device, a fully automated process of ball milling operation is realized, and the automation integration is high.

[0161] In addition, a positioning component can be provided on the outer cover 42 near the protective door to facilitate the positioning of the mobile robot and to place and pick up the ball mill jar on the ball mill 100 after the protective door is opened. The positioning component can include three two-dimensional codes that are spaced and not coplanar, and the orientations of the two-dimensional codes are the same. A touch screen can also be provided on the outer cover 42 to facilitate the experimenter to interact with the experimental equipment through the touch screen and to view the working status of the ball mill 100.

[0162] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship of terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" are based on the orientation or positional relationship described in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0163] What is disclosed above is only a preferred embodiment of the present application, and it certainly cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiment and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
