Description

Technical Field

[0001] The utility model relates to the technical field of lithium processing, in particular to a cutting device for lithium sheets. Background Art

[0002] In some processes, lithium ingots are processed twice to form lithium sheets, and then the lithium sheets are cut into specified sizes. The existing cutting device includes a feeding mechanism, a pressing assembly and a cutting assembly. The feeding mechanism is used to transport lithium sheets; the pressing assembly is located at the discharge end of the feeding mechanism, and the lithium sheets can pass through the pressing assembly. The pressing assembly is used to press the lithium sheets during cutting; the cutting assembly is located at the discharge side of the pressing assembly. The cutting assembly includes a bracket, a cutting drive, a cutting part and a guide part. The pressing assembly is arranged on one side of the bracket, and the guide part is arranged on the other side of the bracket. The cutting part and the guide part are slidably connected in the vertical direction. The cutting drive is arranged on the bracket, and the cutting part is connected to the output end of the cutting drive. The cutting drive can drive the cutting part to rise and fall to cut the lithium sheets. The device can realize automatic feeding and cutting of lithium sheets, save material costs, improve work efficiency, and the cutting is stable, which improves the cutting quality of lithium sheets.

[0003] The existing cutting device has the following problem: it is not convenient to cut the lithium sheet into a specified size.

[0004] Based on the above situation, a cutting device for lithium sheets is urgently needed to solve the problem that it is inconvenient to cut lithium sheets into specified sizes. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the existing cutting device is inconvenient to cut the lithium sheets into specified sizes by transmitting the lithium sheets through the feeding mechanism and the cutting driving member driving the cutting part to rise and fall to cut the lithium sheets.

[0006] The technical solution of the utility model is as follows:

[0007] A cutting device for lithium sheets, comprising:

[0008] A conveying mechanism, used for conveying lithium sheets;

[0009] A cutting mechanism, cooperating with the conveying mechanism and used for cutting the lithium sheets;

[0010] A positioning plate, cooperating with the cutting mechanism and used to position the lithium sheet to control the cutting length of the lithium sheet;

[0011] The adjusting mechanism is connected to the positioning plate and is used to adjust the distance between the positioning plate and the cutting mechanism.

[0012] The existing cutting device transmits lithium sheets through a feeding mechanism, and the cutting drive member drives the cutting part to rise and fall to cut the lithium sheets, but it is not convenient to cut the lithium sheets into a specified size. In this solution, the distance between the positioning plate and the cutting mechanism is adjusted by the adjustment mechanism, so that the lithium sheets can be measured according to the specified size and cut by the cutting mechanism, thereby solving the problem of inconvenience in cutting the lithium sheets into the specified size.

[0013] Furthermore, the present solution does not limit the specific structure of the adjustment mechanism. One feasible solution is: the adjustment mechanism includes a movable seat and a threaded rod cooperating with the movable seat. When this solution is adopted, the movable seat and the positioning plate are driven to move synchronously by the threaded rod to change the distance between the positioning plate and the cutting mechanism. At the same time, due to the self-locking of the thread, the distance between the positioning plate and the cutting mechanism can be kept fixed.

[0014] Furthermore, in order to more accurately adjust the distance between the positioning plate and the cutting mechanism, one feasible solution is that the threaded rod is connected to a servo motor. When this solution is adopted, the servo motor can more accurately control the rotation angle of the threaded rod, thereby more accurately adjusting the distance between the positioning plate and the cutting mechanism.

[0015] Furthermore, the present solution does not limit the specific structure of the conveying mechanism. One feasible solution is: the conveying mechanism includes a roller for clamping the lithium sheet and a conveying motor for driving the roller, and a ratchet is arranged between the roller and the conveying motor. When this solution is adopted, the conveying motor can work continuously. When the roller clamps the lithium sheet and presses the lithium sheet against the positioning plate, the roller is stationary under the action of the ratchet to facilitate cutting by the cutting mechanism.

[0016] Furthermore, in order to prevent the cut lithium sheets from sticking to each other, one feasible solution is: the conveying mechanism also includes a nozzle for spraying isolation oil onto the surface of the lithium sheets. When this solution is adopted, an isolation film can be formed on the surface of the lithium sheets under the action of the nozzle, thereby preventing the cut lithium sheets from sticking to each other.

[0017] Furthermore, the present solution does not limit the specific structure of the cutting mechanism. One feasible solution is that the cutting mechanism includes a cutting tool and a hydraulic rod for driving the cutting tool. When this solution is adopted, the cutting tool is driven by the hydraulic rod to move to cut the lithium sheet.

[0018] Compared with the existing technology, the beneficial effects of the utility model are:

[0019] 1. By adjusting the distance between the positioning plate and the cutting mechanism through the adjusting mechanism, the lithium sheet can be measured according to the specified size and cut through the cutting mechanism, thus solving the problem of inconvenience in cutting the lithium sheet into the specified size;

[0020] Second, since the adjustment mechanism includes a movable seat and a threaded rod matched with the movable seat, the threaded rod drives the movable seat and the positioning plate to move synchronously to change the distance between the positioning plate and the cutting mechanism. At the same time, due to the self-locking of the thread, the distance between the positioning plate and the cutting mechanism can be kept fixed;

[0021] Third, since the conveying mechanism also includes a nozzle for spraying isolation oil onto the surface of the lithium sheet, an isolation film can be formed on the surface of the lithium sheet under the action of the nozzle, thereby preventing the cut lithium sheets from sticking to each other.

[0032] It should be noted that relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0033] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0034] Example:

[0035] Please refer to Figure 1 , a cutting device for lithium sheets, comprising:

[0036] Conveying mechanism 1, used for conveying lithium sheets;

[0037] A cutting mechanism 2, which cooperates with the conveying mechanism 1 and is used to cut the lithium sheets;

[0038] A positioning plate 3 cooperates with the cutting mechanism 2 and is used to position the lithium sheet to control the cutting length of the lithium sheet;

[0039] The adjusting mechanism 4 is connected to the positioning plate 3 and is used for adjusting the distance between the positioning plate 3 and the cutting mechanism 2 .

[0040] The existing cutting device transmits lithium sheets through a feeding mechanism, and the cutting drive member drives the cutting part to rise and fall to cut the lithium sheets, but it is not convenient to cut the lithium sheets into a specified size. In this solution, the distance between the positioning plate 3 and the cutting mechanism 2 is adjusted by the adjustment mechanism 4, so that the lithium sheets can be measured according to the specified size and cut by the cutting mechanism 2, which solves the problem of inconvenience in cutting the lithium sheets into the specified size.

[0041] Reference Figure 2 This solution does not limit the specific structure of the adjustment mechanism 4. One feasible solution is: the adjustment mechanism 4 includes a movable seat 41 and a threaded rod 42 that cooperates with the movable seat 41. When this solution is adopted, the threaded rod 42 drives the movable seat 41 and the positioning plate 3 to move synchronously to change the distance between the positioning plate 3 and the cutting mechanism 2. At the same time, due to the self-locking of the thread, the distance between the positioning plate 3 and the cutting mechanism 2 can be kept fixed.

[0042] In order to more accurately adjust the distance between the positioning plate 3 and the cutting mechanism 2, one feasible solution is: the threaded rod 42 is connected to a servo motor 43. When this solution is adopted, the servo motor 43 can more accurately control the rotation angle of the threaded rod 42, thereby more accurately adjusting the distance between the positioning plate 3 and the cutting mechanism 2.

[0043] This solution does not limit the specific structure of the conveying mechanism 1. One feasible solution is: the conveying mechanism 1 includes a roller 11 for clamping the lithium sheet and a conveying motor 12 for driving the roller 11. A ratchet is arranged between the roller 11 and the conveying motor 12. When this solution is adopted, the conveying motor 12 can work continuously. When the roller 11 clamps the lithium sheet and presses the lithium sheet against the positioning plate 3, the roller 11 is stationary under the action of the ratchet to facilitate cutting by the cutting mechanism 2.

[0044] Reference Figure 1 , Figure 3 and Figure 5 In order to prevent the cut lithium sheets from sticking to each other, one feasible solution is that the conveying mechanism 1 also includes a nozzle 13 for spraying isolation oil onto the surface of the lithium sheet. When this solution is adopted, an isolation film can be formed on the surface of the lithium sheet under the action of the nozzle 13, thereby preventing the cut lithium sheets from sticking to each other.

[0045] Preferably, a recovery tank 14 is provided below the nozzle 13, and the fallen isolation oil is collected by the recovery tank 14 for reuse.

[0046] Reference Figure 2 and Figure 4 This solution does not limit the specific structure of the cutting mechanism 2. One feasible solution is: the cutting mechanism 2 includes a cutting tool 21 and a hydraulic rod 22 for driving the cutting tool 21. When this solution is adopted, the cutting tool 21 is driven by the hydraulic rod 22 to move to cut the lithium sheet.

[0047] The working principle of this embodiment:

[0048] The conveying motor 12 drives the roller 11 to rotate, clamp and continuously convey the lithium sheet. During the conveying process, the isolation oil is sprayed on the surface of the lithium sheet through the nozzles 13 arranged on both sides of the lithium sheet. When the lithium sheet is pressed against the positioning plate 3, the ratchet makes a sound and the roller 11 stops. The hydraulic rod 22 drives the cutting tool 21 to cut the lithium sheet. The cut lithium sheet falls naturally, and the ratchet continues to drive the roller 11 to rotate and convey the lithium sheet, and this reciprocating process is repeated.

[0049] In order to solve the problem that it is inconvenient to cut the lithium sheets into specified sizes, in this solution, the distance between the positioning plate 3 and the cutting mechanism 2 is adjusted by the adjustment mechanism 4, so that the lithium sheets can be measured according to the specified size and cut by the cutting mechanism 2, thereby solving the problem that it is inconvenient to cut the lithium sheets into specified sizes.

[0050] In order to keep the distance between the positioning plate 3 and the cutting mechanism 2 fixed, in the present embodiment, since the adjustment mechanism 4 includes a movable seat 41 and a threaded rod 42 cooperating with the movable seat 41, the threaded rod 42 drives the movable seat 41 and the positioning plate 3 to move synchronously to change the distance between the positioning plate 3 and the cutting mechanism 2. At the same time, due to the self-locking of the thread, the distance between the positioning plate 3 and the cutting mechanism 2 can be kept fixed.

[0051] In order to prevent the cut lithium sheets from sticking to each other, in the present embodiment, since the conveying mechanism 1 also includes a nozzle 13 for spraying isolation oil onto the surface of the lithium sheets, an isolation film can be formed on the surface of the lithium sheets under the action of the nozzle 13, thereby preventing the cut lithium sheets from sticking to each other.

[0052] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
