Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and more specifically, to a hanging shaft device and a transfer vehicle having therein. Background Technology

[0002] The production process of lithium batteries involves multiple steps, including slurry preparation, coating, rolling, slitting, die-cutting, and winding. Before coating, the metal alloy block needs to be rolled into a sheet, then the sheet is rolled up and transferred to the feeding end of the coating equipment. The sheet is then unloaded by an unwinding machine. After coating, the electrode sheet needs to be rolled up again for further processing. During this process, the electrode rolls need to be manually transferred multiple times.

[0003] In related technologies, operators typically use a transfer vehicle to transport electrode rolls. However, the hanging shaft structure on this transfer vehicle cannot adequately secure the electrode rolls, causing them to sway during transport. This can lead to problems such as the electrode rolls detaching from the hanging shaft and falling off, resulting in damage to the electrode rolls. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention propose a hanging shaft device that can fully fix the electrode roll and reduce damage during the handling of the electrode roll.

[0008] According to an embodiment of the present invention, the mounting device of the pole piece, by providing a stop member between the second end of the pole piece and the transport section, allows the first driving component to drive the stop member to protrude from the side wall of the pole piece after the electrode roll is fitted onto the transport section. This ensures the electrode roll is stably fitted onto the transport section under the stopping action of the stop member, preventing the electrode roll from shifting axially along the pole piece and falling off from the second end of the pole piece. Furthermore, when the operator needs to remove the electrode roll from the pole piece or install it on the pole piece, the first driving component can be manipulated to retract the stop member into the pole piece, thus preventing interference with the removal and placement of the electrode roll.

[0041] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] The following is a reference appendix. Figures 1 to 8 The hanging shaft device 1 and the transfer vehicle having the same are described according to embodiments of the present invention.

[0043] like Figures 3 to 8 As shown, the axle mounting device 1 according to an embodiment of the present invention includes: a fixing seat 11, a hanging shaft 12, and a check valve assembly 13. The fixing seat 11 is adapted to be mounted on the vehicle frame 2, and the first end of the hanging shaft 12 (e.g., Figure 5The rear end of the middle hanging shaft 12 is connected to the fixed base 11, and the second end of the hanging shaft 12 (such as...) Figure 5 The front end of the middle hanging shaft 12 extends in a direction away from the fixed base 11, and the hanging shaft 12 is provided with a transport section 121 for mounting the pole roll.

[0044] The anti-return assembly 13 includes a stop member 131 and a first drive component 132. The stop member 131 is located at the second end of the hanger shaft 12 (e.g., Figure 5 Between the front end of the middle shaft 12 and the front end of the transport section 121, the first drive component 132 is connected to the stop component 131. The first drive component 132 is used to drive the stop component 131 to move between the stop position and the retraction position. In the stop position, the stop component 131 protrudes from the side wall of the shaft 12, and in the retraction position, the stop component 131 retracts into the shaft 12.

[0045] According to an embodiment of the present invention, the mounting device 1, by providing a stop 131 between the second end of the mounting shaft 12 and the transport section 121, allows the first driving component 132 to drive the stop 131 to protrude from the side wall of the mounting shaft 12 after the electrode roll is fitted onto the transport section 121. This ensures the electrode roll is stably fitted onto the transport section 121 under the stopping action of the stop 131, preventing the electrode roll from shifting axially along the mounting shaft 12 and falling off from the second end of the mounting shaft 12. Furthermore, when the operator needs to remove the electrode roll from or install it on the mounting shaft 12, the first driving component 132 can be manipulated to retract the stop 131 into the mounting shaft 12, thus preventing interference with the removal and placement of the electrode roll. Therefore, the mounting device 1 of the present invention can effectively secure the electrode roll, reducing damage during electrode roll transport, and is simple to operate and convenient to use.

[0046] Optionally, such as Figure 5 and Figure 6 As shown, the side wall of the hanger shaft 12 is provided with a check port 122, and the hanger shaft 12 has an installation channel 123. The check port 122 communicates with the installation channel 123. In the stop position, the stop member 131 protrudes out of the check port 122. In the retracted position, the stop member 131 retracts into the installation channel 123. At least a portion of the first drive component 132 is disposed within the installation channel 123. Because the stop member 131 can retract into the installation channel 123, and some parts of the first drive component 132 are arranged within the installation channel 123, the structure of the hanger shaft 12 can be made more compact, and the problem of scratching the electrode roll due to contact between the first drive component 132 and the electrode roll is avoided.

[0047] Optionally, such as Figures 5 to 7As shown, the first drive component 132 includes a linkage component 1321 and a first operating component 1322. The linkage component 1321 is located inside the installation channel 123, and the first operating component 1322 is located at the first end of the hanging shaft 12 and outside the installation channel 123. The first operating component 1322 is connected to the stop component 131 through the linkage component 1321.

[0048] It is understandable that, such as Figures 5 to 7 As shown, the linkage 1321 extends along the front-rear direction of the mounting channel 123. The front end of the linkage 1321 is connected to the stop 131, and the rear end of the linkage 1321 is connected to the first operating member 1322. The operator can stand on the fixed base 11 to manipulate the first operating member 1322, so that the first operating member 1322 drives the linkage 1321 to move. The linkage 1321 can drive the stop 131 to move between the stop position and the retraction position. The shaft hanging device 1 of the embodiment of the present invention, by setting the first driving member 132 to the above structure, can facilitate the operator to control the stop 131, and by setting the first operating member 1322 at the rear end of the shaft 12, it will not interfere with the handling of the pole roll.

[0049] In one example, such as Figures 5 to 7 As shown, the check valve assembly 13 also includes a first elastic element (not shown), which is connected to the hanger 12 and the stop 131. The first elastic element has an elastic force that drives the stop 131 to move from the retraction position toward the stop position; for example, the first elastic element is a spring. The linkage 1321 includes a flexible cable 13211, one end of which is connected to the stop 131, and the other end of which is connected to a first operating member 1322. It is understood that when it is necessary to move the stop 131 to the retraction position, the operator can manipulate the first operating member 1322 to pull the flexible cable 13211. The flexible cable 13211 can drive the stop 131 to move, so that the stop 131 retracts downward into the mounting channel 123. At this time, the first elastic element is compressed and has elastic potential energy. When it is necessary to move the stop 131 to the stop position, the operator can manipulate the first operating member 1322 to release the flexible cable 13211, the first elastic member is released, thereby driving the stop 131 to move upward and protrude out of the check port 122.

[0050] Specifically, such as Figures 5 to 7As shown, the check valve assembly 13 also includes a plurality of cable guide wheels 133, which are spaced apart within the mounting channel 123 and are used to guide the flexible cable 13211. In an embodiment of the present invention, there are two cable guide wheels 133. One cable guide wheel 133 is located at the lower end of the stop member 131 to vertically guide the flexible cable 13211, and the other cable guide wheel 133 is located at the rear end of the mounting channel 123 and adjacent to the first operating member 1322 to horizontally guide the flexible cable 13211. The flexible cable 13211 is respectively wrapped around the two cable guide wheels 133, thereby supporting and guiding the flexible cable 13211 and improving the stability of the transmission of the flexible cable 13211.

[0051] In another example, the linkage 1321 can be a pull rod structure (not shown), with the front end of the pull rod connected to the stop member 131 and the rear end of the pull rod connected to the first operating member 1322. The first operating member 1322 can directly push or pull the pull rod to move the stop member 131 between the stop position and the retracted position.

[0052] Optionally, such as Figure 5 and Figure 6 As shown, the first end (front end) of the stop member 131 is pivotally connected to the hanging shaft 12. In the stop position, the second end (rear end) of the stop member 131 gradually tilts upward, and the second end of the stop member 131 is closer to the transport section 121 than the first end. It can be understood that when the flexible cable 13211 pulls the rear end of the stop member 131, the stop member 131 will pivot with its front end as the pivot point. When the flexible cable 13211 is released, the stop member 131 will rotate upward under the action of the first elastic element to return to the stop position.

[0053] Furthermore, since the stop 131 gradually slopes upwards from front to back, the electrode roll can pass through the stop 131 and slide directly onto the transport section 121 during installation. Specifically, when the electrode roll passes the stop 131, the stop 131 can automatically press down and move to the retraction position, thus avoiding interference with the installation of the electrode roll. After the electrode roll passes the stop 131, the stop 131 can return to the stop position under the action of the first elastic member. Therefore, the stop 131 of the shaft mounting device 1 in the embodiment of the present invention adopts the above-described structural arrangement, which can reduce the operator's operating steps, facilitate the transfer of the electrode roll to the shaft 12, and is convenient to operate with good performance.

[0054] In some embodiments, such as Figure 7 and Figure 8As shown, the hanging shaft device 1 also includes a tensioning assembly 14, which includes a tensioning component 141 and a second driving component 142. The side wall of the transport section 121 is provided with a tensioning port 124, and the hanging shaft 12 is provided with an installation channel 123. The tensioning component 141 is located in the tensioning port 124, and at least a portion of the second driving component 142 is located in the installation channel 123. The second driving component 142 is connected to the tensioning component 141 to drive the tensioning component 141 to move between a tensioned position and a retracted position. In the tensioned position, the tensioning component 141 protrudes from the tensioning port 124, and in the retracted position, the tensioning component 141 retracts into the installation channel 123.

[0055] Understandably, after the electrode roll is placed in the transport section 121, the tensioning component 141 will protrude from the tensioning port 124 at the tensioning position. Therefore, the tensioning component 141 will abut against the inner wall of the electrode roll drum, thereby providing a certain tensioning force to the electrode roll. This avoids the problem of the electrode roll swaying relative to the hanging shaft 12 and prevents the electrode roll from loosening. In turn, it avoids the problem of misaligned spiral layers between the inner and outer layers of the electrode roll, improves the reliability of the electrode roll transport, and ensures the quality of the electrode roll.

[0056] Optionally, such as Figure 5 , Figure 7 and Figure 8 As shown, the second drive component 142 includes a bracket 1421, a cam portion 1422, and a second operating member 1423. Both the bracket 1421 and the cam portion 1422 are disposed within the mounting channel 123. The first end of the second operating member 1423 (e.g., ...) Figure 5 The front end of the second operating member 1423 is connected to the cam portion 1422, and the second end of the second operating member 1423 (such as...) Figure 5 The rear end of the second operating member 1423 extends out of the mounting channel 123. The cam part 1422 is pivotally connected to the bracket 1421, and the cam surface of the cam part 1422 abuts against the tensioning member 141.

[0057] Understandably, the operator can rotate the second operating member 1423 to move the cam surface of the cam portion 1422 relative to the tensioning member 141. When the protrusion of the cam portion 1422 is in contact with the tensioning member 141, the tensioning member 141 can move outward from the tensioning opening 124, thereby tensioning the electrode roll. When the concave portion of the cam portion 1422 is in contact with the tensioning member 141, the tensioning member 141 can retract to the tensioning opening 124 to release the electrode roll, allowing the operator to remove the electrode roll from the hanger 12.

[0058] The shaft-hanging device 1 of the present invention, by setting the second drive component 142 to the above structure, can tighten and release the pole roll by manual operation without being constrained by air source and electricity, thereby ensuring the flexibility of use of the shaft-hanging device 1, and the structure is simple and easy to process and manufacture.

[0059] Optionally, such as Figure 8 As shown, the tensioning component 141 includes a guide post 1411, a tensioning plate 1412, and a second elastic member 1413. The first end of the guide post 1411 (as shown) Figure 8 The lower end of the guide post 1411 is connected to the tensioning plate 1412, and the second end of the guide post 1411 (such as...) Figure 8 The upper end of the guide post 1411 abuts against the cam portion 1422, and the guide post 1411 is slidable relative to the bracket 1421. The second elastic member 1413 is connected to the guide post 1411 and the bracket 1421, and the second elastic member 1413 has an elastic force that drives the guide post 1411 to move toward the cam portion 1422.

[0060] Understandably, when the operator rotates the second operating member 1423, the second operating member 1423 drives the cam portion 1422 to rotate. The convex portion of the cam portion 1422 abuts against the guide post 1411, causing the guide post 1411 to move downward. The guide post drives the tensioning plate 1412 to move downward simultaneously, so that the tensioning plate 1412 abuts against the inner wall of the electrode roll. When the operator drives the second operating member 1423 to rotate and reset, the concave portion of the cam portion 1422 gradually abuts against the guide post 1411. Under the action of the second elastic member 1413, the guide post 1411 moves upward, causing the tensioning plate 1412 to retract to the tensioning port 124.

[0061] Optionally, such as Figure 8 As shown, the tensioning plate 1412 is provided with an elastic pressure strip 1414 on the side away from the guide post 1411 to avoid the problem of damaging the pole winding drum when the tensioning plate 1412 is tightened.

[0062] In some embodiments, such as Figure 1 , Figure 5 and Figure 6 As shown, the hanging shaft device 1 also includes a sensor assembly, which includes a material sensor 151, a check sensor 152, a tension sensor, and a controller 153. The material sensor 151, the check sensor 152, and the tension sensor are all connected to the controller 153. The material sensor 151 is located in the conveying section 121 to detect whether there is material in the conveying section 121. The check sensor 152 is connected to the stop member 131 to detect the position of the stop member 131. The tension sensor is connected to the tensioning member 141 to detect the position of the tensioning plate 1412.

[0063] Specifically, such as Figure 4 and Figure 5As shown, the material sensor 151 is installed on the wall of the conveying section 121, and the wiring of the material sensor 151 is arranged in the installation channel 123. The check sensor 152 is installed at the lower end of the stop member 131. When the stop member 131 rotates downward, the stop member 131 will contact the check sensor 152.

[0064] The material sensor 151 works in conjunction with the tension sensor and the check sensor 152. When an electrode roll is mounted on the transport section 121 of the shaft 12, the material sensor 151 is pressed shut, and at this time, the check component 13 needs to pop out (the stop 131 moves to the stop position), and the tension component 14 presses the roll (the tension plate 1412 moves to the tension position). If either the check component 13 or the tension component 14 fails to meet the requirements, the shaft mounting device 1 will emit a buzzer to alert the employee to check, thus preventing abnormalities during the electrode roll transport process caused by employee operational errors and improving the foolproof effect of the shaft mounting device 1.

[0065] In some embodiments, such as Figure 3 and Figure 4 As shown, the hanging shaft device 1 also includes multiple universal ball bearings 16, which are spaced apart on the side wall of the transport section 121. For example, there are three rows of universal ball bearings 16, all of which are spaced apart along the axial direction of the hanging shaft 12. It can be understood that the universal ball bearings 16 can rotate relative to the hanging shaft 12, thereby reducing the friction during the transport of the electrode roll, preventing damage to the electrode roll, reducing the workload of employees, and improving work efficiency.

[0066] like Figures 1 to 3 As shown, another embodiment of the transfer vehicle of the present invention includes a shaft mounting device 1 and a frame 2. The shaft mounting device 1 is the shaft mounting device 1 of the present invention, and the fixing seat 11 is mounted on the frame 2, and the fixing seat 11 is movable along the vertical direction of the frame 2.

[0067] According to an embodiment of the present invention, the transfer vehicle, by providing a stop 131 between the second end of the hanging shaft 12 and the transport section 121, allows the first driving component 132 to drive the stop 131 to protrude from the side wall of the hanging shaft 12 after the electrode roll is fitted onto the transport section 121. This ensures the electrode roll is stably fitted onto the transport section 121 under the stopping action of the stop 131, preventing the electrode roll from shifting axially along the hanging shaft 12 and falling off the second end of the hanging shaft 12. Furthermore, when the operator needs to remove the electrode roll from or install it on the hanging shaft 12, the first driving component 132 can be manipulated to retract the stop 131 into the hanging shaft 12, thus preventing interference with the removal and placement of the electrode roll. Therefore, the transfer vehicle of this embodiment can effectively secure the electrode roll, reducing damage during transport, and is simple to operate and convenient to use.

[0068] Optionally, such as Figure 1 and Figure 3 As shown, the transfer vehicle also includes a slide rail assembly 3, which includes a slider 31 and a guide rail 32. The guide rail 32 is mounted on the frame 2 and extends along the vertical direction of the frame 2. The slider 31 is mounted on the fixed seat 11 and slides along the length of the guide rail 32. For example, there are two sets of slide rail assemblies 3, and the two sets of slide rail assemblies 3 are respectively arranged on the left and right sides of the fixed seat 11, which can improve the stability of the vertical movement of the hanging shaft device 1. In addition, the fixed seat 11 and the frame 2 slide together using the guide rail 32 and the slider 31, which simplifies the connection method of the transfer vehicle and facilitates its manufacturing.

[0069] Optionally, such as Figure 1 and Figure 2 As shown, the transfer vehicle also includes a lifting assembly 4, which includes a drive motor 41, a lead screw 42, and a nut 43. The nut 43 is mounted on the fixed base 11, and the lead screw 42 is mounted on the frame 2 and extends along the vertical direction of the frame 2. The drive motor 41 is connected to the lead screw 42, and the nut 43 cooperates with the lead screw 42.
