Utility Model Content

[0003] The present application provides a cleaning device and a battery production equipment, which can remove foreign matter between battery cells and improve the reliability of the battery cells.

[0004] In the first aspect, the present application provides a cleaning device, including a driving mechanism, a cleaning component and a floating component, the driving mechanism including a driving part and an executing part connected to the driving part; the floating component including a first floating mechanism, the first floating mechanism connecting the executing part and the cleaning component, the driving part is at least used to drive the cleaning component to move along a first direction through the executing part and the first floating mechanism, and the floating component is configured to enable the cleaning component to float along a second direction relative to the executing part, and the first direction intersects the second direction.

[0005] The driving unit drives the floating assembly and the cleaning assembly to move along the first direction, so that the cleaning assembly can clean the gaps between the battery cells along the first direction, clean the metal foreign matter, and reduce the damage of the metal foreign matter to the battery cells. The cleaning assembly floats along the first direction through the first floating mechanism, so as to avoid the cleaning assembly from hard collision with the battery cells during the cleaning process, causing damage to the battery cells.

[0008] In some optional embodiments, the first floating mechanism further includes an elastic member disposed between the actuator and the first sliding member along the second direction. The elastic member enables the cleaning assembly to be reset to an initial state in time, reduces the deviation of the cleaning assembly, and better runs along the gap between the battery cells.

The floating member is extended along a third direction, and along the third direction, the side of the floating member away from the execution part exceeds the cleaning component, and the third direction intersects with the first direction and the second direction.

[0014] By setting the floating part, the floating part can float relative to the battery cell through the first floating mechanism, thereby driving the cleaning component to clean along the gaps between the battery cells, reducing the direct contact between the cleaning component and the battery cells, expanding the selection range of the material and structure of the cleaning component, and further reducing the damage to the battery cell through the specific material setting of the floating part.

The second direction Y may be the column direction of the battery device perpendicular to the first direction, or the arrangement direction of the two side walls of the gap 401.

[0062] The driving unit 310 drives the floating assembly 100 and the cleaning assembly 200 to move along the first direction X, so that the cleaning assembly 200 cleans the gap 401 between the battery cells 403 along the first direction X, cleans the metal foreign matter, and reduces the damage of the metal foreign matter to the battery cells 403. The cleaning assembly 200 floats along the first direction X through the first floating mechanism 110, so as to avoid the cleaning assembly 200 from hard collision with the battery cells 403 during the cleaning process, thereby preventing the battery cells 403 from being damaged.

[0081] The first guide member 112 is a structure that guides the movement direction of the first sliding member 111. The first guide member 112 is in a strip shape, a rod shape, or the like.

[0082] The first guide member 112 is fixedly mounted on the execution part 320 or detachably mounted on the execution part 320. The first guide member 112 is connected to the execution part 320 in whole or in part.

[0097] like Figure 3 As shown, in some optional embodiments, the first floating mechanism 110 further includes a second sliding member 115 and a second guide member 114 , the second sliding member 115 is connected to the cleaning assembly 200 , and the second sliding member 115 is configured to slide along the third direction Z relative to the second guide member 114 .

[0105] By providing a second guide member 114 along the third direction Z, when the cleaning assembly 200 accidentally touches the upper surface of the battery cell 403 during the process of falling into the gap 401 between the battery cells 403, the cleaning assembly 200 floats along the third direction Z, thereby reducing the hard collision with the upper surface of the battery cell 403.

[0110] Exemplarily, the stopper 116 is a protrusion along the second direction Y and a protrusion of the cleaning assembly 200, or a stopper or the like provided on the second guide member 114. The stopper 116 may be a strip, column, sheet, spherical, or the like. The stopper 116 may be connected to the second guide member 114 or the cleaning assembly 200 by bonding, welding, or clamping.

[0111] In other examples, a limiting member 116 is provided at other positions of the second guide member 114 and the cleaning assembly 200 to limit the upper limit position of the cleaning assembly 200 relative to the second guide member 114. The movement range of the cleaning assembly 200 is between the upper limit position and the lower limit position.

[0112] The second limiting member 116 prevents the cleaning assembly 200 from being separated from the first floating mechanism 110 .

[0113] Figure 4 for Figure 1 Another structural schematic diagram at A in the middle.

[0114] like Figure 1 and Figure 4 As shown, in some optional embodiments, the first floating mechanism 110 includes a telescopic member 117 connected along the second direction Y between the cleaning assembly 200 and the execution part 320 .

[0115] The telescopic member 117 may be a telescopic structure such as a spring, a return cylinder, etc. When the cleaning assembly 200 hits the battery cell 403, the telescopic member 117 on one side is retracted after receiving force, and the telescopic member 117 on the other side is extended.

[0116] The telescopic member 117 with a certain resistance can reduce excessive shaking of the cleaning assembly 200 in the gap 401 between the battery cells 403 , thereby improving the stability of the cleaning assembly 200 .

[0117] Continue to refer Figure 4 In some optional embodiments, the execution part 320 further includes a second detection mechanism 324 disposed on the execution part 320 , and the second detection mechanism 324 is at least used to sense the position of the cleaning component 200 along the second direction Y relative to the execution part 320 .

[0118] The second detection mechanism 324 may be one or more.

[0119] The second detection mechanism 324 may be a proximity switch, a position sensor, etc. For example, the proximity switch may be implemented in an inductive, capacitive, Hall, photoelectric, etc. The position sensor may be a photoelectric encoder, an ultrasonic sensor, a laser ranging sensor, etc.

[0120] The position of the cleaning assembly 200 along the second direction Y is detected by the second detection mechanism 324 to prevent the cleaning assembly 200 from reaching the floating limit position and causing damage to the battery cell 403 .

[0121] In one embodiment of the present application, a second detection mechanism 324 is disposed on each of the first walls 132 of the two first mounting portions 322 of the mounting frame 321 to detect the position of the cleaning assembly 200 and the two first mounting portions 322. The second detection mechanism 324 may be provided with an alarm function.

[0122] Figure 5 for Figure 1 Another structural schematic diagram at A in the middle; Figure 6 for Figure 5 Schematic diagram of the connection structure between the middle floating member 101 and the cleaning assembly 200.

[0123] like Figure 5 and Figure 6 As shown, in some optional embodiments, the floating component 100 also includes a floating member 101, which is connected to the first floating mechanism 110 and the cleaning component 200. The floating member 101 is extended along a third direction Z, and along the third direction Z, the side of the floating member 101 away from the execution part 320 exceeds the cleaning component 200, and the third direction Z intersects with the first direction X and the second direction Y.

[0124] The number of the floating member 101 may be one or more.

[0125] In one example, the floating member 101 is in the shape of a rod. The cross section of the floating member 101 can be in the shape of a circle, a triangle, a square, a ring, or the like.

[0126] The floating member 101 may be made of metal or non-metal, for example, copper, iron, engineering plastic, aluminum alloy, carbon fiber, etc. In one example, the floating material is carbon fiber, which reduces damage to the battery cell 403 when in contact with the battery cell 403 and is a non-stick material.

[0127] The floating member 101 can be detachably connected or fixedly connected to the first floating mechanism 110 and the cleaning assembly 200. In one example, the first floating mechanism 110 is connected to the cleaning assembly 200 via the floating member 101.

[0128] By setting the floating part 101, the floating part 101 can float relative to the battery cell 403 through the first floating mechanism 110, thereby driving the cleaning component 200 to clean along the gap 401 between the battery cells 403, reducing the direct contact between the cleaning component 200 and the battery cells 403, expanding the selection range of the material and structure of the cleaning component 200, and further reducing the damage to the battery cell 403 through the specific material setting of the floating part 101.

[0129] In one embodiment of the present application, the cleaning assembly 200 is connected to the floating member 101 along the first direction X. For example, the cleaning assembly 200 is directly connected to the floating member 101, and the cleaning assembly 200 is indirectly connected to the floating member 101 through other structures.

[0130] Figure 7 for Figure 5 A top view of the float assembly 100 is shown.

[0131] like Figure 5 and Figure 7 As shown, in some optional embodiments, the floating assembly 100 also includes a rotating mechanism 120, which includes a first rotating part 121 and a second rotating part 122 that are relatively rotatably connected along an axis extending along a third direction Z, the first rotating part 121 is connected to the floating member 101, and the second rotating part 122 is connected to the first floating mechanism 110.

[0132] The rotating mechanism 120 is a structure having at least two parts that can rotate relative to each other around its own axis. The rotating mechanism 120 can be a bearing, a turntable, or other structures.

[0133] For example, the first rotating portion 121 and the second rotating portion 122 may be disposed inwardly and outwardly along the radial direction of the rotating mechanism 120 , or may be disposed up and down along the third direction Z.

[0134] The floating member 101 is rotated by the rotating mechanism 120 , so that when the floating member 101 contacts the battery cell 403 , friction damage to the battery cell 403 caused by the floating member 101 is reduced.

[0135] In one embodiment of the present application, the cleaning assembly 200 is connected to the floating member 101 via a rotating mechanism 120 .

[0136] Figure 8 for Figure 7 A schematic diagram of the second floating mechanism 130 is shown; Fig. 9 for Figure 7 A schematic diagram of a floating member 101 is shown.

[0137] like Figures 5 to 9As shown, in some optional embodiments, the floating assembly 100 also includes a second floating mechanism 130 nested and connected to the first rotating part 121, the second floating mechanism 130 includes a first wall 132 and a second wall 131 arranged opposite to each other and a groove 133 recessed from the first wall 132 to the second wall 131, and the groove 133 extends along the third direction Z; the floating member 101 includes a rod body 102 and a key 103 protruding from the rod body 102, the rod body 102 is arranged on the first wall 132, and the key 103 and the groove 133 are configured to cooperate and slide along the third direction Z.

[0138] The second floating mechanism 130 is a structure that allows the floating member 101 to float along the third direction Z. For example, the second floating mechanism 130 is a bushing.

[0139] In one example, the second wall 131 and the first rotating portion 121 are interference fit.

[0140] The groove 133 is a concave structure that penetrates the second floating mechanism 130 along the third direction Z.

[0141] The rod body 102 is partially or entirely provided with a key 103 along the third direction Z. The key 103 is slidably matched with the groove 133 .

[0142] The second floating mechanism 130 is nested in the rotating mechanism 120 to simplify the structure of the floating assembly 100. The key 103 of the floating member 101 floats along the groove 133 of the second floating mechanism 130, so that the floating member 101 can float along the third direction Z during rotation, thereby improving the flexibility of the floating member 101.

[0143] Continue to refer Figure 4 and Figure 5 In some optional embodiments, the execution part 320 further includes a first detection mechanism 325 disposed on the execution part 320 , and the first detection mechanism 325 is at least used to sense the position of the cleaning component 200 relative to the execution part 320 along the third direction Z.

[0144] The first detection mechanism 325 may be one or more.

[0146] The first detection mechanism 325 detects the position of the cleaning assembly 200 along the third direction Z to prevent the cleaning assembly 200 from reaching the floating limit position and causing damage to the battery cell 403 .

[0147] In one embodiment, the first detection mechanism 325 is disposed on the first wall 132 of the second mounting portion 323. The first detection mechanism 325 may be provided with an alarm function.

[0151] The cleaning assembly 200 includes a suction nozzle 201 and a negative pressure device 202 which are connected to each other.
