Description

Technical Field

[0001] This utility model relates to the technical field of battery cell production, and in particular to a rotary battery cell testing device. Background Technology

[0002] When testing battery cells, since battery cells generally have the shape characteristics of a block and have multiple edges and corners, it is necessary to test each edge and corner of the battery cell based on the requirements of the battery cell manufacturing process.

[0003] In current mainstream technologies, CT scans are generally used to perform non-destructive imaging and detection of the internal structure of battery cells, such as the corners or other internal structures. CT, also known as computed tomography, is a detection method that uses X-rays and computer technology to generate tomographic images of the interior of an object, similar to medical CT scans. In battery cell CT scans, an X-ray source guides the X-rays to penetrate the battery cell, and a detector receives the X-rays on the other side and records projection information from different angles. The computer then uses a reconstruction algorithm to synthesize a three-dimensional image.

[0004] In related technologies, battery cell testing equipment generally includes a CT testing device and a testing platform. In order to achieve automatic feeding to the CT testing device and improve efficiency, the testing platform generally includes a turntable and multiple battery cell fixtures set on the turntable. The battery cell fixtures are used to fix the battery cells. The turntable rotates to drive the multiple battery cell fixtures to move alternately to the testing area of ​​the CT testing device for testing.

[0005] However, for battery cells of different sizes, the position of the edges that need to be inspected relative to the center of the battery cell fixture may differ. Existing battery cell inspection equipment has difficulty quickly adjusting the position of the battery cell so that the edges that need to be inspected are aligned with the inspection area of ​​the CT inspection device. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a rotary battery cell testing device that can quickly adjust the position of the battery cell so that the corners of the battery cell to be tested are aligned with the testing area of ​​the CT testing device.

[0007] The rotary battery cell testing device according to an embodiment of the present invention includes:

[0008] The CT detection device has a detection area set in a first and second direction that are horizontal and perpendicular to each other, as well as a vertical direction.

[0009] A battery cell support device is located on one side of the detection area along the first direction, and includes a rotating mechanism, a battery cell fixture, and a first displacement module. The battery cell fixture is used to fix the battery cell, and the rotating mechanism rotates to drive the battery cell fixture in and out of the detection area.

[0010] The first displacement module is used to drive the rotating mechanism to move along the first direction so that the battery cells on the battery cell fixture are aligned with the detection area.

[0011] The rotary battery cell testing device according to the embodiments of this utility model has at least the following beneficial effects:

[0012] 1. This utility model utilizes a rotating mechanism to drive the battery cell fixture into and out of the testing area, enabling the battery cell fixture to enter and exit the testing area along the circumferential motion trajectory of the rotating mechanism's rotation axis. On the one hand, the battery cells at all stations on the rotating mechanism can move synchronously to the next station while the rotating mechanism is rotating, which is beneficial to improving loading and unloading efficiency. On the other hand, the circumferential motion trajectory of the rotating mechanism driving the battery cell fixture has a compact structure and occupies less space than a linear conveyor layout with the same number of stations, which is beneficial to saving the area occupied by equipment layout.

[0013] 2. This utility model, by setting a first displacement module to precisely adjust the overall position of the battery cell along a first direction, enables the detection target edges of battery cells of different sizes to quickly align with the detection area, thus solving the problem of adapting the battery cell detection equipment to the edge positions of battery cells of different sizes. This allows the battery cell detection equipment to adapt to battery cells of different sizes without changing the fixture, reducing downtime for adjustment and improving the versatility of the equipment.

[0014] According to some embodiments of the present invention, the cell-carrying device is provided on both sides of the detection area along the first direction.

[0015] The advantage is that by providing cell-carrying devices on both sides of the detection area along the first direction, this utility model enables the CT detection device to simultaneously detect cells on both sides, thus achieving parallel detection of dual-station cells and improving detection efficiency.

[0016] According to some embodiments of the present invention, the CT detection device includes a frame, a rotating ring rotatably disposed on the frame about an axis extending about the first direction, and a detection component disposed on the rotating ring, wherein the detection component is provided with a detection area;

[0017] The detection component is used to simultaneously detect battery cells located on two battery cell carriers that enter the detection area;

[0018] Alternatively, two detection components may be provided, with each component disposed on a different side of the rotating ring along the first direction. Each component is used to detect the cells on the two cell carriers that have entered the detection area.

[0019] The advantages of this invention are: by using the detection component to simultaneously detect cells located on two cell carriers entering the detection area, the detection area of ​​a single detection component can cover cells on both sides, thus reducing equipment costs; or, by setting detection components on both sides of the rotating ring along the first direction, with each of the two detection components used to detect cells entering the detection area on the two cell carriers, the dual detection components can work independently, meeting the differentiated detection needs of cells on both sides and improving the detection flexibility of the cell detection equipment.

[0020] According to some embodiments of the present invention, the battery cell carrying device further includes a second displacement module, which is used to drive the battery cell fixture to move along the second direction.

[0021] The advantage of this invention is that by setting a second displacement module, which is used to drive the battery cell fixture to move along a second direction, the second displacement module, in combination with the first displacement module, can arbitrarily adjust the position of the battery cell in the horizontal plane, ensuring that the edges are accurately aligned with the detection area, and adapting to more complex battery cell structures.

[0022] According to some embodiments of the present invention, the battery cell carrying device further includes a third displacement module, which is used to drive the battery cell fixture to move in the up-down direction.

[0023] The advantages are: by setting a third displacement module, which is used to drive the battery cell fixture to move in the vertical direction, the battery cell carrying device can be adjusted in the vertical dimension of the battery cell, thus meeting the testing needs of battery cells of different thicknesses or special edges and corners, and improving the adaptability of the battery cell testing equipment.

[0024] According to some embodiments of the present invention, the battery cell carrying device includes at least two battery cell fixtures, which are arranged circumferentially along the rotation axis of the rotating mechanism. The rotating mechanism rotates to drive the at least two battery cell fixtures to alternately enter and exit the detection area.

[0025] The advantages of this invention are: by setting at least two battery cell fixtures, which are arranged circumferentially along the rotation axis of the rotating mechanism, the rotating mechanism rotates to drive at least two battery cell fixtures to alternately enter and exit the detection area. Thus, the rotation of multiple battery cell fixtures realizes the automatic feeding, detection and unloading of battery cells in a continuous process, which significantly reduces the idle waiting time of the equipment and helps to improve production efficiency.

[0026] According to some embodiments of the present invention, the battery cell carrying device includes at least two battery cell fixtures and at least two third displacement modules. The at least two third displacement modules are arranged circumferentially on the rotating mechanism along the rotation axis of the rotating mechanism. The battery cell fixtures are disposed on the third displacement modules, and the third displacement modules are used to drive the battery cell fixtures to move in the up and down direction.

[0027] The advantages of this invention are: by including at least two cell fixtures and at least two third displacement modules in the cell carrying device, the at least two third displacement modules are arranged circumferentially on the rotating mechanism along the rotation axis of the rotating mechanism, the cell fixtures are mounted on the third displacement modules, and the third displacement modules are used to drive the cell fixtures to move in the vertical direction. Thus, each cell fixture can independently adjust its vertical position through the corresponding third displacement module, thereby facilitating independent compensation of the vertical position differences of each cell fixture, or supporting the detection of cell of different sizes, which is beneficial to improving the adaptability of the cell testing equipment.

[0028] According to some embodiments of the present invention, the battery cell fixture includes a fixing component and a first power component. The fixing component is used to fix the battery cell, and the first power component is used to drive the fixing component to rotate along the vertical axis so that the battery cell moves its different edges to the detection area for detection.

[0029] The advantages of this invention are: by including a fixing component and a first power component in the battery cell fixture, the fixing component is used to fix the battery cell, and the first power component is used to drive the fixing component to rotate along the vertical axis so that the battery cell moves its different edges to the detection area for detection. It can be understood that by using the first power component to drive the fixing component to rotate, the battery cell can be rotated, and multiple edges of the battery cell can be switched to the detection area in sequence. This allows the fixing component to complete the scanning of all edges in a single clamping of the battery cell, avoiding the repeated positioning error caused by multiple clamping of the battery cell.

[0030] According to some embodiments of the present invention, the battery cell fixture further includes a fourth displacement module, which is used to drive the fixing component and the power component to move along the first direction and the second direction.

[0031] The advantage of this invention is that by setting a fourth displacement module, which drives the fixed component and the power component to move along the first and second directions, the horizontal position can be precisely adjusted on the basis of the rotation of the fixed component, ensuring that each corner can be accurately aligned with the detection ray path in the detection area.

[0032] According to some embodiments of the present invention, the rotating mechanism includes a fixed base, a rotating base rotatably disposed on the fixed base, a second power component that drives the rotating base to rotate, and a medium transmission module disposed between the fixed base and the rotating base, wherein the medium transmission module is used to transmit electricity and / or gas between the fixed base and the rotating base;

[0033] The medium transmission module is configured as a connector, which is used to guide the wires and / or air pipes to move within a limited rotation angle.

[0034] Alternatively, the medium transmission module may be configured as a slip ring and / or a rotary joint, wherein the slip ring is used for electrical and / or pneumatic transmission between the rotating base and the fixed base, and the rotary joint is used for pneumatic transmission between the rotating base and the fixed base.

[0035] The advantages are: by setting a medium transmission module between the fixed base and the rotating base, this utility model can solve the problem of electrical and / or pneumatic transmission between the rotating base and the fixed base, ensuring that the wires and / or air pipes are not disturbed when the rotating base rotates. When the rotating base rotates at a limited angle, the medium transmission module can be set as a conduit, which is conducive to achieving the anti-tangling effect of wires and / or air pipes at a low cost. When the rotating base rotates at a limited angle or an unlimited angle, setting the medium transmission module as a slip ring and / or rotary joint can ensure stable transmission of energy and signals during rotation, and improve the long-term reliability of the equipment.

[0047] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This invention describes a rotary battery cell testing device according to an embodiment of the present invention.

[0048] This invention aims to provide an embodiment of a rotary battery cell testing device.

[0049] Reference Figure 1 and Figure 2 In this embodiment, the rotary cell testing equipment mainly includes a CT testing device 100 and a cell carrying device 120.

[0050] Continue to refer to Figure 1 and Figure 2 The CT detection device 100 has a first direction and a second direction that are horizontal and perpendicular to each other, as well as a vertical direction. The CT detection device 100 is provided with a detection area 110.

[0051] In some specific implementations, the detection area 110 is provided with cell carrying devices 120 on both sides of the first direction.

[0052] It is understandable that by arranging the cell carrier device 120 on both sides of the detection area 110, the CT detection device 100 can detect cells on both sides at the same time, thereby enabling the CT detection device 100 to perform parallel detection of cells at both workstations, which is beneficial to improving detection efficiency.

[0053] In order to enable the battery cells on both sides of the detection area 110 to enter the detection area 110, openings can be provided on both sides of the detection area 110 to accommodate the battery cells entering the detection area 110, so as to realize the detection of the battery cells by the CT detection device 100.

[0054] Specifically, the CT detection device 100 includes a frame 160, a rotating ring 170 rotatably mounted on the frame 160 about an axis extending in a first direction, and a detection component 180 mounted on the rotating ring 170, the detection component 180 having a detection area 110.

[0055] In some specific embodiments, the detection component 180 is used to simultaneously detect cells located on two cell carriers 120 that have entered the detection area 110.

[0056] This embodiment enables the detection component 180 to simultaneously detect the cells located on two cell carrier devices 120 that enter the detection area 110, thereby achieving the coverage of both sides of the cells by the detection area 110 of a single detection component 180, so that a single detection component 180 can detect both sides of the cells at the same time, thus reducing equipment costs.

[0057] Alternatively, in other embodiments, two detection components 180 are provided, with the two detection components 180 respectively disposed on two sides of the rotating ring 170 along the first direction, and the two detection components 180 are respectively used to detect the cells on the two cell carrier devices 120 that enter the detection area 110.

[0058] In this embodiment, detection components 180 are respectively set on both sides of the rotating ring 170 along the first direction. The two detection components 180 are used to detect the cells on the two cell carrier devices 120 that enter the detection area 110. Thus, the dual detection components 180 can work independently, which can meet the differentiated detection needs of the cells on both sides and improve the detection flexibility of the cell detection equipment.

[0059] Furthermore, the detection assembly 180 includes a radiation emitter and a detector, which are disposed opposite to each other on the rotating ring 170. The radiation emitter and the detector together define the detection area 110. The radiation emitter emits detection radiation on one side of the cell, which penetrates the cell, and the detector receives the radiation on the other side of the cell and records the projection information.

[0060] Furthermore, the CT detection device 100 also includes a drive motor, which is fixed on the frame 160. The drive motor is used to drive the rotating ring 170 to rotate, so as to adjust the position of the X-ray emitter and the detector relative to the cell.

[0061] Furthermore, a transmission structure for transmission is provided between the drive motor and the rotating ring 170, through which the drive motor drives the rotating ring 170 to rotate.

[0062] Specifically, the transmission structure can be configured as a transmission belt, with the transmission belt tensioned on the output end of the drive motor and the rotating ring 170, and the drive motor drives the rotating ring 170 to rotate through the transmission belt.

[0063] In other embodiments, the transmission structure may be configured as a gear and a gear ring that mesh with each other. The gear is located at the output end of the drive motor, and the gear ring is located on the outer circumferential surface of the rotating ring 170. The drive motor and the rotating ring 170 are driven by the meshing of the gear and the gear ring.

[0064] It should be explained that CT scanners are existing technology. The structure of the CT scanner 100 in this embodiment, which is not specifically described, can be understood as being the same as that of CT scanners in the prior art. Those skilled in the art should understand its structure and working principle, which will not be elaborated here.

[0065] Reference Figure 3For the cell carrier device 120, the cell carrier device 120 is located on one side of the detection area 110 along the first direction. The cell carrier device 120 includes a rotating mechanism 130, a cell fixture 140 and a first displacement module 150. The cell fixture 140 is used to fix the cell. The rotating mechanism 130 rotates to drive the cell fixture 140 to enter and exit the detection area 110.

[0066] This invention utilizes a rotating mechanism 130 to rotate and drive a battery cell fixture 140 into and out of the inspection area 110. This allows the battery cell fixture 140 to enter and exit the inspection area 110 along the circumferential motion trajectory of the rotating axis of the rotating mechanism 130. On the one hand, the battery cells at all stations on the rotating mechanism 130 can move synchronously to the next station when the rotating mechanism 130 rotates, which is beneficial to improving the loading and unloading efficiency. On the other hand, the circumferential motion trajectory of the rotating mechanism 130 driving the battery cell fixture 140 has a compact structure and occupies less space than a linear conveyor layout with the same number of stations, which is beneficial to saving the area occupied by equipment layout.

[0067] Furthermore, the first displacement module 150 is used to drive the rotation mechanism 130 to move along the first direction so that the battery cell on the battery cell fixture 140 is aligned with the detection area 110.

[0068] This embodiment sets up a first displacement module 150 to precisely adjust the overall position of the battery cell along a first direction, so that the edges of the detection targets of battery cells of different sizes can be quickly aligned with the detection area 110. This solves the problem of adapting the battery cell detection equipment to the edge positions of battery cells of different sizes, so that the battery cell detection equipment can adapt to battery cells of different sizes without changing the fixture, reducing downtime for adjustment and improving the versatility of the equipment.

[0069] Specifically, the first displacement module 150 includes a first slider and a third power component that drives the first slider to slide along a first direction.

[0071] In some specific embodiments, the cell carrier device 120 further includes a second displacement module 190, which is used to drive the cell fixture 140 to move along a second direction. Thus, the second displacement module 190, in combination with the first displacement module 150, can arbitrarily adjust the position of the cell in the horizontal plane to ensure that the edges are precisely aligned with the detection area 110, and adapt to more complex cell structures.

[0072] Specifically, the second displacement module 190 includes a second slider and a fourth power component that drives the second slider to slide along a second direction.

[0073] The fourth power component can be configured as a cylinder; or, the fourth power component can be configured as a second motor and a second screw, the second screw extending along a second direction, the second motor driving the second screw to rotate, the second screw being threadedly connected to the second slider, and the rotation of the second screw driving the second slider to slide along the second direction.

[0074] Furthermore, the cell carrier device 120 also includes a base, on which the second slider can be slidably mounted. A fourth power component is mounted on the base, which drives the second slider to slide along a second direction on the base. A first slider is slidably mounted on the second slider. A third power component is mounted on the second slider, which drives the first slider to slide along a first direction on the second slider. A rotating mechanism 130 or a third displacement module 200 is mounted on the first slider.

[0075] Specifically, when the third power component is configured as a first motor and a first screw, the first motor is fixed on the second slider, and the first screw is rotatably connected to the second slider. When the fourth power component is configured as a second motor and a second screw, the second motor is fixed on the base, and the second screw is rotatably connected to the base.

[0076] In other embodiments, the cell support mechanism further includes a base, on which a first slider is slidably disposed, a third power component is disposed on the base, the third power component drives the first slider to slide on the base along a first direction, a second slider is slidably disposed on the first slider, a fourth power component is disposed on the first slider, the fourth power component drives the second slider to slide on the first slider along a second direction, and a rotation mechanism 130 or a third displacement module 200 is disposed on the second slider.

[0077] Specifically, when the third power component is configured as a first motor and a first screw, the first motor is fixed on the base and the first screw is rotatably connected to the base. When the fourth power component is configured as a second motor and a second screw, the second motor is fixed on the first slider and the second screw is rotatably connected to the first slider.

[0078] In some specific embodiments, the cell carrier device 120 further includes a third displacement module 200, which is used to drive the cell fixture 140 to move in the vertical direction, thereby increasing the cell carrier device 120's ability to adjust the vertical dimension of the cell, meeting the detection requirements of cells of different thicknesses or special edges, and improving the adaptability of the cell detection equipment.

[0079] Specifically, the third displacement module 200 includes a first guide rail extending in the vertical direction and disposed on the rotating mechanism 130, a third slider sliding on the first guide rail, and a fifth power component that drives the third slider to slide in the vertical direction. The battery cell fixture 140 is disposed on the third slider.

[0080] Furthermore, the fifth power component can be configured as a cylinder, which is fixed on the first guide rail.

[0081] In other embodiments, the fifth power component may be configured as a third motor and a third screw, with the third screw extending in the vertical direction, rotatably connected to the first guide rail, and threadedly connected to the third slider. The third motor is fixed on the first guide rail, and the third motor drives the third screw to rotate so as to drive the third slider to slide in the vertical direction.

[0082] In some specific embodiments, the battery cell carrying device 120 includes at least two battery cell fixtures 140. The at least two battery cell fixtures 140 are arranged circumferentially along the rotation axis of the rotating mechanism 130. The rotating mechanism 130 rotates to drive the at least two battery cell fixtures 140 to alternately enter and exit the detection area 110. Thus, the rotation of multiple battery cell fixtures 140 realizes the automatic feeding, detection and unloading of battery cells in a continuous process, which significantly reduces the idle waiting time of the equipment and helps to improve production efficiency.

[0083] In some specific embodiments, the cell carrier device 120 includes at least two cell fixtures 140 and at least two third displacement modules 200. The at least two third displacement modules 200 are arranged circumferentially on the rotating mechanism 130 along the rotation axis of the rotating mechanism 130. The cell fixtures 140 are disposed on the third displacement modules 200. The third displacement modules 200 are used to drive the cell fixtures 140 to move in the vertical direction, so that each cell fixture 140 can independently adjust its vertical position through the corresponding third displacement module 200. This facilitates independent compensation of the vertical position differences of each cell fixture 140, or supports the detection of cells of different sizes, which is beneficial to improving the adaptability of the cell testing equipment.

[0084] Reference Figure 4 In some specific embodiments, the battery cell fixture 140 includes a fixing component 210 and a first power component 220. The fixing component 210 is used to fix the battery cell, and the first power component 220 is used to drive the fixing component 210 to rotate along the vertical axis so that the battery cell moves its different edges to the detection area 110 for detection.

[0085] It is understandable that the first power component 220 drives the fixed component 210 to rotate, thereby realizing the rotation of the battery cell and sequentially switching the multiple edges of the battery cell to the detection area 110. This allows the fixed component 210 to complete the scanning of all edges of the battery cell in a single clamping, avoiding the repeated positioning error caused by multiple clamping of the battery cell.

[0086] Specifically, the fixing component 210 may include a positioning seat, at least two clamping blocks disposed on the positioning seat, and a cylinder that drives the two clamping blocks to move closer and further apart. The positioning seat is used to support the battery cell, and the at least two clamping blocks cooperate to clamp and fix the battery cell.

[0087] In other embodiments, the fixing component 210 may include a vacuum adsorption seat and a vacuum generator. The vacuum adsorption seat is used to support the battery cell. The vacuum adsorption seat is provided with a vacuum adsorption hole located at the bottom of the battery cell. The vacuum generator evacuates the vacuum adsorption hole so that the vacuum adsorption seat adsorbs and fixes the battery cell through the vacuum adsorption hole.

[0088] In some specific embodiments, the first power component 220 is configured as a motor.

[0089] In some specific embodiments, the cell fixture 140 also includes a fourth displacement module 230, which is used to drive the fixing component 210 and the power component to move along the first direction and the second direction. Thus, based on the rotation of the fixing component 210, the ability to finely adjust the horizontal position is superimposed to ensure that each corner can be accurately aligned with the detection ray path in the detection area 110.

[0090] Specifically, the fixed component 210 is rotatably mounted on the fourth displacement module 230, and the first power component 220 is mounted on the fourth displacement module 230, driving the fixed component 210 to rotate.

[0091] In some specific embodiments, the fourth displacement module 230 includes a mounting base, a fourth slider slidably disposed on the mounting base, a sixth power component that drives the fourth slider to slide, a fifth slider slidably disposed on the fourth slider, and a seventh power component that drives the fifth slider to slide. The battery cell fixture 140 is disposed on the fifth slider. One of the fourth slider and the fifth slider slides along a first direction, and the other of the fourth slider and the fifth slider slides along a second direction.

[0092] Furthermore, the sixth power component can be configured as a cylinder, which is fixed on the mounting base and pushes the fourth slider to move. Alternatively, the sixth power component includes a fourth motor and a fourth screw, with the fourth screw rotatably connected to the mounting base and threadedly connected to the fourth slider. The fourth motor is fixed on the mounting base and drives the fourth screw to rotate in order to drive the fourth slider to move.

[0093] In some specific embodiments, the seventh power component can be configured as a cylinder, which is fixed on the fourth slider and pushes the fifth slider to move. Alternatively, the seventh power component includes a fifth motor and a fifth screw, which is rotatably connected to the fourth slider and threadedly connected to the fifth slider. The fifth motor is fixed on the fourth slider and drives the fifth screw to rotate to drive the fifth slider to move.

[0094] In some specific embodiments, the rotating mechanism 130 includes a fixed base 240, a rotating base 250 rotatably disposed on the fixed base 240, a second power component that drives the rotating base 250 to rotate, and a medium transmission module 260 disposed between the fixed base 240 and the rotating base 250. The medium transmission module 260 is used to transmit electricity and / or gas between the fixed base 240 and the rotating base 250, thereby solving the problem of electricity and / or gas transmission between the rotating base 250 and the fixed base 240, and ensuring that the wires and / or gas pipes are not disturbed when the rotating base 250 rotates.

[0095] In some specific embodiments, the media transmission module 260 is configured as a conduit for guiding the movement of wires and / or air pipes within a limited rotation angle.

[0096] Understandably, when the rotating base 250 rotates at a limited angle, the medium transmission module 260 can be set as a conduit, which is beneficial for achieving the anti-tangling effect of wires and / or air pipes at low cost.

[0097] It should be explained that the connecting pipe is set on the rotating base 250 along the rotation axis of the rotating base 250. The wires and / or air pipes on the rotating base 250 enter the connecting pipe and are uniformly led out from the end of the connecting pipe to connect to the power supply and / or air source. In this way, the wires and / or air pipes on the rotating base 250 can be guided by the connecting pipe to the rotation axis of the rotating base 250 and led out from the rotation axis of the rotating base 250 to connect to the power supply and / or air source. This effectively prevents the wires and / or air pipes from getting tangled together or tangled on the components of the rotating base 250 when the rotating base 250 rotates.

[0098] Alternatively, in other embodiments, the medium transfer module 260 is configured as a slip ring and / or a rotary joint, the slip ring being used for electrical and / or pneumatic transfer between the rotating base 250 and the fixed base 240, and the rotary joint being used for pneumatic transfer between the rotating base 250 and the fixed base 240.

[0099] It is understandable that when the rotating base 250 rotates at a limited angle or an unlimited angle, setting the media transmission module 260 as a slip ring and / or rotary joint can ensure stable transmission of energy and signals during rotation and improve the long-term reliability of the equipment.

[0100] Specifically, when the medium transmission module 260 only needs to transmit air, the medium transmission module 260 can be configured as a pneumatic slip ring or a rotary joint; when the medium transmission module 260 only needs to transmit electricity, the medium transmission module 260 can be configured as an electric slip ring; when the medium transmission module 260 needs to transmit both air and electricity, the medium transmission module 260 can be configured as a pneumatic-electric slip ring. The pneumatic-electric slip ring is a type of slip ring in the prior art that can transmit both air and electricity simultaneously.
