Detailed Implementation

[0047] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0048] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0049] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0050] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0051] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0052] First, it should be noted that the X, Y, and Z directions in the embodiments of this application are referred to in the appendix. Figure 1 The marked directions. Among them, the axes in the X direction, Y direction, and Z direction intersect each other.

[0053] like Figures 1-12 As shown, according to a first aspect of the embodiments of this application, a transmission mechanism is provided, including a first mounting plate 1, a second mounting plate 2, a first mounting seat 3, a second mounting seat 4, and a first roller 5; the first mounting plate 1 and the second mounting plate 2 are spaced apart in the Y direction, and the first mounting plate 1 has a first groove 11; the first mounting seat 3 is detachably disposed in the first groove 11; the first roller 5 is located between the first mounting plate 1 and the second mounting plate 2, one end of the first roller 5 is rotatably connected to the first mounting seat 3, and the other end of the first roller 5 is rotatably connected to the second mounting plate 2.

[0054] The transmission mechanism in this application is located in the cleaning machine and is used to transport battery cells by rotating the first roller 5.

[0055] like Figures 1-7 As shown, the transmission mechanism includes a first mounting plate 1, a second mounting plate 2, a first mounting base 3, and a first roller 5; the first mounting plate 1 and the second mounting plate 2 are spaced apart in the Y direction, in other words, there is a gap between the first mounting plate 1 and the second mounting plate 2, one end of the first roller 5 is mounted on the first mounting plate 1 through the first mounting base 3, the other end of the first roller 5 is rotatably connected to the second mounting plate 2, and the first roller 5 is located between the first mounting plate 1 and the second mounting plate 2.

[0056] Specifically, a first groove 11 is provided on the first mounting plate 1; one end of the first roller 5 is rotatably connected to the first mounting base 3, and the other end of the first roller 5 is rotatably connected to the second mounting plate 2. The first roller 5 can rotate about its own axis relative to the first mounting plate 1 and the second mounting plate 2. The axis of the first roller 5 is in the same direction as the Y direction. The battery cells are transported by rotating the first roller 5. The first mounting base 3 is detachably disposed in the first groove 11. That is to say, the first roller 5 is mounted on the first mounting plate 1 by the first mounting base 3.

[0057] In related technologies, the first roller 5 is usually directly installed in the grooves of the first mounting plate 1 and the second mounting plate 2. A cover plate is set in the groove to fix the first roller 5. If the first roller 5 is directly installed in the groove, there will be a certain gap between the first roller 5 and the groove. The first roller 5 may vibrate when rotating for a long time, which will cause the water film covering the battery cell to fall off, affecting the quality of the battery cell.

[0058] The transmission mechanism in this application mounts one end of the first roller 5 to the first mounting base 3, and then mounts the first mounting base 3 in the first groove 11. This avoids gaps between the first roller 5 and the first groove 11, thus preventing unstable rotation of the first roller 5. Consequently, it also prevents the water film covering the battery cell from falling off, thereby improving the quality of the battery cell.

[0059] The other end of the first roller is installed on the second mounting plate in the following manner:

[0060] In one specific implementation, such as Figure 12 As shown, the second mounting plate 2 has a second groove 21, and the other end of the first roller 5 is disposed in the second groove 21 and rotates relative to the second groove 21. In this embodiment, since one end of the first roller 5 is mounted in the first groove 11 through the first mounting base 3, directly mounting the other end of the first roller 5 in the second groove 21 can also solve the problem of unstable rotation of the first roller 5, and this installation method is simple.

[0061] In another specific embodiment, the second mounting plate 2 is provided with a second groove 21; the transmission mechanism further includes a second mounting base 4, which is detachably mounted in the second groove 21, and the other end of the first roller 5 is rotatably connected to the second mounting base 4. Specifically, the second mounting plate 2 is provided with a second groove 21, the first groove 11 and the second groove 21 are arranged opposite to each other in the Y direction, the other end of the first roller 5 is rotatably connected to the second mounting base 4, and the second mounting base 4 is detachably mounted in the second groove 21. That is, the first roller 5 is mounted on the second mounting plate 2 by the second mounting base 4. In this embodiment, both ends of the first roller 5 are mounted on the first mounting base 3 and the second mounting base 4, and then the first mounting base 3 is mounted in the first groove 11, and the second mounting base 4 is mounted in the second groove 21; thereby, the rotational stability of the first roller 5 can be further improved, and the quality of the battery cell can be further improved.

[0062] In an optional embodiment, the inner walls 111 of both the first groove 11 and the second groove 21 are provided with a first sliding groove 112 and a second sliding groove 113, the first sliding groove 112 and the second sliding groove 113 being spaced apart in the Y direction, and the inner wall 111 forming a first protrusion 114 between the first sliding groove 112 and the second sliding groove 113; the outer walls 31 of both the first mounting base 3 and the second mounting base 4 are provided with a first limiting plate 32 and a second limiting plate 33, the first limiting plate 32 and the second limiting plate 33 being spaced apart in the Y direction, and a third sliding groove 34 being formed between the first limiting plate 32 and the second limiting plate 33; the first limiting plate 32 is located in the first sliding groove 112, the second limiting plate 33 is located in the second sliding groove 113, and the first protrusion 114 is located in the third sliding groove 34.

[0063] like Figure 3 , Figure 5 and Figure 6As shown, the inner walls 111 of the first groove 11 and the second groove 21 are both provided with a first sliding groove 112 and a second sliding groove 113; that is, the inner walls 111 of the first groove 11 are provided with a first sliding groove 112 and a second sliding groove 113, and the inner walls 111 of the second groove 21 are provided with a first sliding groove 112 and a second sliding groove 113, and the structures of the first groove 11 and the second groove 21 are the same; the outer walls 31 of the first mounting base 3 and the second mounting base 4 are both provided with a first limiting plate 32 and a second limiting plate 33, that is, the outer walls 31 of the first mounting base 3 are provided with a first limiting plate 32 and a second limiting plate 33, and the outer walls 31 of the second mounting base 4 are provided with a first limiting plate 32 and a second limiting plate 33, and the structures of the first mounting base 3 and the second mounting base 4 are the same; therefore, the transmission mechanism of this application only requires one type of mounting base, which can be adapted to the first groove 11 and the second groove 21, thereby saving costs and simplifying installation.

[0064] In this embodiment, the first groove 11 and the first mounting base 3 are used as examples for explanation. Specifically, the inner wall 111 of the first groove 11 is provided with a first sliding groove 112 and a second sliding groove 113. The first sliding groove 112 and the second sliding groove 113 are arranged opposite to each other in the Y direction, and the inner wall 111 between the first sliding groove 112 and the second sliding groove 113 forms a first protrusion 114. The first mounting base 3 includes an outer wall 31, on which a first limiting plate 32 and a second limiting plate 33 are provided. The first limiting plate 32 and the second limiting plate 33 are spaced apart in the Y direction, and a third sliding groove 34 is formed between the first limiting plate 32 and the second limiting plate 33. The first mounting base 3 is installed in the first groove 11, and the first... The inner wall 111 of the groove 11 abuts against the outer wall 31 of the first mounting base 3. The first limiting plate 32 is located in the first sliding groove 112, the second limiting plate 33 is located in the second sliding groove 113, and the first protrusion 114 is located in the third sliding groove 34. The first sliding groove 112, the second sliding groove 113, and the third sliding groove 34 can provide a guiding function for the first mounting base 3 to be installed in the first sliding groove 112, thus facilitating the installation of the first mounting base 3 into the first groove 11. Furthermore, the first sliding groove 112 can restrict the movement of the first limiting plate 32 in the Y and X directions, and the second sliding groove 113 can restrict the movement of the second limiting plate 33 in the Y and X directions, thereby restricting the movement of the first mounting base 3 in the Y and X directions.

[0065] The first mounting base 3 and the first mounting plate 1 can be connected by screws, thereby fixing the first mounting base 3 onto the first mounting plate 1 and enabling it to be detachable.

[0066] In one specific embodiment, the first limiting plate 32 protrudes from the outer wall 31 in the Z direction, while the second limiting plate 33 does not protrude from the outer wall 31 in the Z direction. Specifically, the transmission mechanism is disposed within the receiving cavity of the cleaning tank. The space between the first mounting plate 1 and the second mounting plate 2 forms a first sub-receiving cavity, the space between the first mounting plate 1 and the first side plate of the cleaning tank forms a second sub-receiving cavity, and the space between the second mounting plate 2 and the second side plate of the cleaning tank forms a third sub-receiving cavity. In this embodiment, the first limiting plate 32 protrudes from the outer wall 31 of the first mounting base 3 in the Z direction. When the first mounting base 3 is installed in the first groove 11, the first limiting plate 32 of the first mounting base 3 abuts against the first sliding groove 112 of the first groove 11. The first limiting plate 32 of the second mounting base 3 can separate the cleaning fluid between the first sub-receiving cavity and the second sub-receiving cavity, preventing the cleaning fluid of the first sub-receiving cavity and the cleaning fluid of the second sub-receiving cavity from flowing to each other through the first groove 11. When the second mounting base 4 is installed in the second groove 21, the first limiting plate 32 of the second mounting base 4 abuts against the first sliding groove 112 of the second groove 21. The first limiting plate 32 of the second mounting base 4 can separate the cleaning fluid between the first sub-receiving cavity and the third sub-receiving cavity, preventing the cleaning fluid of the first sub-receiving cavity and the cleaning fluid of the third sub-receiving cavity from flowing to each other through the first groove 11. Since the first limiting plate 32 can play a separating role, in order to save costs and reduce processing difficulty, the second limiting plate 33 does not need to protrude from the outer wall 31 in the Z direction.

[0067] In another specific embodiment, the first limiting plate 32 protrudes from the outer wall 31 in the Z direction, and the second limiting plate 33 protrudes from the outer wall 31 in the Z direction. Specifically, the transmission mechanism is disposed within the receiving cavity of the cleaning tank. The space between the first mounting plate 1 and the second mounting plate 2 forms a first sub-receiving cavity, the space between the first mounting plate 1 and the first side plate of the cleaning tank forms a second sub-receiving cavity, and the space between the second mounting plate 2 and the second side plate of the cleaning tank forms a third sub-receiving cavity. In this embodiment, the first limiting plate 32 protrudes from the outer wall 31 of the first mounting base 3 in the Z direction. When the first mounting base 3 is installed in the first groove 11, the first limiting plate 32 abuts against the first sliding groove 112. The first limiting plate 32 can separate the cleaning fluid between the first sub-receiving cavity and the second receiving cavity, preventing... The cleaning fluid in the first and second sub-receiving cavities is prevented from flowing to each other through the first groove 11. When the second mounting base 4 is installed in the second groove 21, the first limiting plate 32 abuts against the first sliding groove 112. The first limiting plate 32 can separate the cleaning fluid between the first and third sub-receiving cavities, preventing the cleaning fluid in the first and third sub-receiving cavities from flowing to each other through the first groove 11. In order to reduce the installation difficulty and prevent the workers from installing the first and second mounting bases 3 and 4 in reverse, the second limiting plate 33 is also set to protrude from the outer wall 31 in the Z direction. Therefore, the position of the first limiting plate 32 and the second limiting plate 33 does not need to be considered during installation, thus reducing the installation difficulty.

[0068] In one optional embodiment, the first mounting base 3 has a first mounting hole 35, the second mounting base 4 has a second mounting hole 41, one end of the first roller 5 is rotatably connected to the first mounting hole 35 through a first bearing, and the other end of the first roller 5 is rotatably connected to the second mounting hole 41 through a second bearing.

[0072] like Figure 5 , Figure 6 and Figure 11 As shown, the first mounting base 3 is provided with a first mounting groove 36, which is spaced apart from the first mounting hole 35 in the Z direction.

The first sub-mounting plate 12 has a first connecting groove 121 and a second protrusion 122 at its end.

The width of the third protrusion 132 is smaller than the width of the first connecting groove 121, and the width of the second protrusion 122 is smaller than the width of the second connecting groove 131; and / or

[0075] The second mounting plate 2 includes a third sub-mounting plate 22 and a fourth sub-mounting plate 23.

The width of the fourth protrusion 222 is smaller than the width of the third connecting groove 221, and the width of the fifth protrusion 232 is smaller than the width of the fourth connecting groove 231.

[0083] In one optional embodiment, the transmission mechanism includes a plurality of first mounting seats 3, a plurality of second mounting seats 4, a plurality of first rollers 5 and a plurality of second rollers 6, wherein the first mounting plate 1 is provided with a plurality of first grooves 11 spaced apart along the X direction; and the second mounting plate 2 is provided with a plurality of second grooves 21 spaced apart along the X direction.

[0084] Each of the first grooves 11 is provided with a first mounting seat 3, each of the second grooves 21 is provided with a second mounting seat 4, a first roller 5 is rotatably connected to the corresponding first mounting seat 3 and the second mounting seat 4 respectively, and a second roller 6 is rotatably connected to the corresponding first mounting seat 3 and the second mounting seat 4 respectively.

[0086] Specifically, the first mounting plate 1 has a plurality of first grooves 11, which are spaced apart along the X direction, and each first groove 11 has a first mounting seat 3; the first mounting seat 3 has a plurality of second grooves 21, which are spaced apart along the X direction, and each second groove 21 has a second mounting seat; so the plurality of first rollers 5 and the plurality of second rollers 6 are mounted on the first mounting plate 1 and the second mounting plate 2.

[0087] In this embodiment, the solar cells can be moved along the X direction by a plurality of first rollers 5 and a plurality of second rollers 6 to achieve the conveying of the solar cells.

[0088] In one optional embodiment, the transmission mechanism further includes a transmission assembly 7, which includes a motor, a transmission shaft 72, and a plurality of transmission components 73. The transmission shaft 72 is connected to the output end of the motor, and the plurality of transmission components 73 are connected to the transmission shaft 72.

[0089] Two adjacent first rollers 5 form roller group a, and each transmission member 73 can drive the two first rollers 5 of the corresponding roller group a to rotate through the transmission shaft 72.

[0090] like Figure 1 , Figure 10 and Figure 11As shown, the transmission mechanism also includes a transmission component 7, which is used to drive a plurality of first rollers 5 to rotate around their own axis.

[0091] Specifically, the transmission assembly 7 includes a motor, a transmission shaft 72, and multiple transmission components 73; wherein, the transmission shaft 72 is connected to the output end of the motor, and the transmission shaft 72 can be connected to the output end of the motor through a coupling, and the motor can drive the transmission shaft 72 to rotate.

[0092] The transmission mechanism includes multiple first rollers 5. Two adjacent first rollers 5 form roller group a. It can be understood that if the transmission mechanism includes four first rollers 5, that is, two roller groups a, along the X direction, the first first roller 5 and the second first roller 5 form one roller group a, the third first roller 5 and the fourth first roller 5 form one roller group a; if the transmission mechanism includes eight first rollers 5, that is, four roller groups a, along the X direction, the first first roller 5 and the second first roller 5 form one roller group a, the third first roller 5 and the fourth first roller 5 form one roller group a, the fifth first roller 5 and the sixth first roller 5 form one roller group a, the seventh first roller 5 and the eighth first roller 5 form one roller group a.

[0093] Each transmission component 73 can drive the two first rollers 5 of a roller group a to rotate via the transmission shaft 72, without requiring each first roller 5 to be driven separately by a transmission component 73. This reduces the distance between two adjacent first rollers 5 and improves the stability of the cell conveying.

[0094] In an optional embodiment, each of the transmission components 73 includes a first gear 731, a second gear 732, a third gear 733, a fourth gear 734, and a fifth gear 735, wherein the first gear 731 is disposed on the transmission shaft 72;

[0095] The second gear 732 and the third gear 733 are spaced apart in the Y direction on one of the first rollers 5 in the roller group a, the fourth gear 734 is disposed on the other first roller 5 in the roller group a, and the fifth gear 735 is disposed on the first mounting plate 1. The first gear 731 meshes with the second gear 732, and the fifth gear 735 meshes with the third gear 733 and the fourth gear 734 respectively.

[0096] like Figure 1As shown, each transmission component 73 includes a first gear 731, a second gear 732, a third gear 733, a fourth gear 734, and a fifth gear 735. Specifically, the first gear 731 is mounted on the transmission shaft 72, and the axial direction of the first gear 731 is the same as that of the transmission shaft 72. The first gears 731 of the multiple transmission components 73 are spaced apart along the axial direction of the transmission shaft 72, and the axial direction of the transmission shaft 72 is the same as that of the X direction. The second gear 732 and the third gear 733 are both mounted on one of the first rollers 5 in the roller group a, and the axial direction of the second gear 732 is the same as that of the first roller 5. The axial direction of the third gear 733 is the same as that of the first roller 5. The fourth gear 734 is mounted on another first roller 5 in the roller group a. The axial direction is the same as that of the first roller 5; the fifth gear 735 is disposed on the first mounting plate 1, and the fifth gear 735 is located between two adjacent first grooves 11 in the X direction. The first gear 731 meshes with the second gear 732, and the fifth gear 735 meshes with the third gear 733 and the fourth gear 734 respectively. Therefore, the power is transmitted to the transmission shaft 72 by the motor, and then through the meshing of the first gear 731 and the second gear 732, the first roller 5 with the second gear 732 can be driven to rotate. The third gear 733 is mounted on the first roller 5, so the third gear 733 will rotate accordingly. The third gear 733 meshes with the fifth gear 735 and the fourth gear 734, thereby driving the other first roller 5 to rotate, thus realizing the simultaneous driving of the rotation of two first rollers 5. In this embodiment, because the distance between two adjacent first rollers 5 is reduced, there is not enough space to install the corresponding first gear 731. Therefore, the two adjacent first rollers 5 cannot be driven by the first gear 731. Thus, a fourth gear 734 can be provided to drive the two first rollers 5 to rotate through the first gear 731.

[0097] Preferably, the first gear 731 is a helical gear, the second gear 732 is a helical gear, the third gear 733 is a spur gear, the fourth gear 734 is a spur gear, and the fifth gear 735 is a spur gear.

[0098] In one alternative embodiment, the transmission assembly 7 further includes a support base 75, the support base 75 having a through hole 751, and the transmission shaft 72 passing through the through hole 751 via a third bearing.

[0099] like Figure 1As shown, the transmission assembly 7 also includes a support base 75, on which a through hole 751 is provided. The axis of the through hole 751 is in the same direction as the X direction. The transmission shaft 72 is located in the inner ring of the third bearing, and the outer ring of the third bearing is located in the through hole 751. In this embodiment, the support base 75 can provide support and stability for the transmission shaft 72. Through the third bearing, the frictional force during the rotation of the transmission shaft 72 can be reduced, thereby improving the stability of the first roller 5 during rotation.

[0100] According to a second aspect of the embodiments of this application, a cleaning machine is provided, including a cleaning tank and a transmission mechanism. The cleaning tank includes a receiving cavity for containing cleaning fluid; the transmission mechanism is disposed in the receiving cavity.

[0101] The cleaning machine includes a cleaning tank and a transmission mechanism. The cleaning tank has a receiving cavity for holding cleaning fluid. The transmission mechanism is located inside the receiving cavity and divides the receiving cavity into a first sub-receiving cavity, a second sub-receiving cavity, and a third sub-receiving cavity. The first sub-receiving cavity is located between the first mounting plate 1 and the second mounting plate 2. The second sub-receiving cavity is located between the first mounting plate 1 and the first side plate of the cleaning tank.
