Description

Technical Field

[0001] The present application relates to the technical field of lithium battery manufacturing, and particularly relates to a magnetic substance separation device for a die-cutting device. Background Art

[0002] With the rapid development of technology, the types of electronic intelligent devices are increasing day by day. Along with the rising price of fossil fuels and environmental protection issues, higher standards are required for batteries. In recent years, the rapid development of lithium-ion batteries has made their advantages prominent.

For example, transportation, electronic products, medical, aviation, military, energy storage, etc.

[0003] The self-discharge reaction of lithium-ion batteries is inevitable.

[0004] Currently, the lithium battery sheet-making process includes homogenization, coating, rolling, slitting, and die-cutting. This process is the basis for ensuring product performance. After the lithium-ion battery electrode sheet undergoes slurry coating, drying, and rolling, a three-layer composite structure of a current collector and two coatings on both sides is formed. According to the battery design structure and specifications, a die-cutting device is required to further cut the electrode sheet into strips and cut the foil material. During the processing of the die-cutting device and the transfer process of the sheet-making, some fine magnetic foreign objects are often generated. If they are brought into the electrode sheet, it will affect the finished product performance of the product, and even cause fire or explosion. To reduce the foreign object risk, improve product quality, and improve customer satisfaction, it is necessary to remove magnetic foreign objects. Summary of the Invention

Detailed implementation manners

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0044] See Figure 1 and Figure 2As shown in the figure, an apparatus for separating magnetic substances for a die-cutting device provided by an embodiment of the present application includes a dust removal box 1, an electromagnetic plate 2, a longitudinal movement assembly 3, and a transverse movement assembly 4. A dust removal port 11 and an entrance / exit 12 are provided on the dust removal box 1. The transverse movement trajectory of the electromagnetic plate 2 enters the inner cavity of the dust removal box 1 through the entrance / exit 12. The entrance / exit 12 allows the electromagnetic plate 2 to enter and exit. The electromagnetic plate 2 carries adsorbed magnetic substances such as iron filings and magnetic powder and enters the inner cavity of the dust removal box 1 from the entrance / exit 12. The material of the electromagnetic plate 2 is mainly an electromagnet. By switching the current, the magnetic field of the electromagnet can be changed from originally adsorbing magnetic powder to repelling magnetic powder, and the magnetic powder is discharged from the dust removal port 11 of the dust removal box 1. Since the upper surface of the electromagnetic plate 2 mainly functions for adsorption, the dust removal port 11 can be provided above the dust removal box 1. At the same time, in order to prevent the magnetic powder from flying randomly to the lower side when repelling the magnetic powder, a dust removal port 11 can also be provided below the dust removal box 1 to discharge the magnetic powder. The longitudinal movement assembly 3 is connected to the electromagnetic plate 2 and is used to drive the electromagnetic plate 2 to move longitudinally. Specifically, after adsorbing magnetic powder, the longitudinal movement assembly 3 drives the electromagnetic plate 2 to enter the dust removal box 1 for dust removal. After completion, the electromagnetic plate 2 is driven to leave the dust removal box 1. The transverse movement assembly 4 is connected to the longitudinal movement assembly 3 and is used to drive the longitudinal movement assembly 3 to move transversely.

[0045] In the present application, the position of the electromagnetic plate 2 is adjusted through the longitudinal movement assembly 3 and the transverse movement assembly 4, so that the position of the separation device for removing magnetic substances can be regulated, the risk of magnetic foreign objects that may be caused during the production of the battery is reduced, the product quality is improved, and the customer satisfaction is increased.

[0046] It can be understood that the horizontal and vertical directions in the present application are two mutually perpendicular directions in the horizontal plane, so as to adjust the position of the electromagnetic plate 2 in the left-right direction and the front-back direction.

[0047] In order to realize the longitudinal movement of the electromagnetic plate 2, in some preferred embodiments, a specific implementation solution is provided. Specifically, refer to Figure 2 and Figure 3 As shown, the longitudinal movement assembly 3 includes a first limit block 30, a longitudinal movement fixing block 31, a first lead screw 32, a first hand wheel 33, and a first guide rod 34. The two first limit blocks 30 are arranged at intervals. The longitudinal movement fixing block 31 is located between the two first limit blocks 30, and the electromagnetic plate 2 is fixed on the longitudinal movement fixing block 31. The two ends of the first lead screw 32 are respectively rotatably connected to the two first limit blocks 30, for example, through bearings. One end of the first lead screw 32 extends out of one of the first limit blocks 30 and is connected to the first hand wheel 33. The first lead screw 32 is threadedly connected to the longitudinal movement fixing block 31. The two ends of the first guide rod 34 are respectively fixed to the two first limit blocks 30 and pass through the longitudinal movement fixing block 31.

[0048] By rotating the first handwheel 33, the first lead screw 32 is driven to rotate synchronously. Since the first lead screw 32 is screwed to the longitudinal movement fixing block 31, the first lead screw 32 has a tendency to drive the longitudinal movement fixing block 31 to rotate synchronously. However, due to the presence of the first guide rod 34, the longitudinal movement fixing block 31 is changed from a rotational motion to a linear motion along the axial direction of the first lead screw 32, thereby realizing the synchronous longitudinal movement of the electromagnetic plate 2 along the axial direction of the first lead screw 32.

[0049] To achieve precise control of the longitudinal distance, refer to Figure 2 and Figure 3 As shown, a first counter 35 is also connected to the first lead screw 32. The first counter 35 rotates synchronously with the first lead screw 32 and starts counting when rotating, and the counter value jumps according to the number of turns.

[0050] To facilitate the installation of the electromagnetic plate 2, refer to Figure 2 As shown, a magnetic plate mounting plate 36 is installed on the longitudinal movement fixing block 31, and the electromagnetic plate 2 is installed on the magnetic plate mounting plate 36.

[0051] Since there are many and scattered parts such as the first limit block 30 and the longitudinal movement fixing block 31, in order to facilitate the overall installation of the longitudinal movement assembly 3, refer to Figure 3 As shown, the first limit block 30 is installed on the first mounting bottom plate 37, and only the first mounting bottom plate 37 needs to be installed on the transverse movement assembly 4.

[0052] It can be understood that the number of the above-mentioned first guide rods 34 can be determined according to actual needs. For example, refer to Figure 3 As shown, two first guide rods 34 are provided and are respectively located on both sides of the first lead screw 32, and the longitudinal movement fixing block 31 can move on the first guide rods 34.

[0053] Since the electromagnetic plate 2 is relatively large as a whole, in order to provide good support for the electromagnetic plate 2, refer to Figure 2 As shown, the longitudinal movement assembly 3 further includes a longitudinal slide rail 38. A longitudinal slider 39 is provided on the longitudinal slide rail 38, and the longitudinal slider 39 is connected to the electromagnetic plate 2.

[0054] Further, when the electromagnetic plate 2 is installed on the magnetic plate mounting plate 36, the longitudinal slider 39 is connected to the magnetic plate mounting plate 36.

[0055] To achieve the transverse movement of the electromagnetic plate 2, in some preferred embodiments, a specific implementation solution is provided. Specifically, refer to Figure 2 and Figure 4As shown, the transverse movement assembly 4 includes a second limit block 40, a second lead screw 41, a second handwheel 42, a transverse slide rail 43, a transverse slider 44, and a transverse movement fixing block 45. The two second limit blocks 40 are arranged at intervals and are located on both sides of the dust removal box 1. The two ends of the second lead screw 41 are respectively rotatably connected to the two second limit blocks 40, for example, through bearings. One end of the second lead screw 41 extends out of one of the second limit blocks 40 and is connected to the second handwheel 42. The second lead screw 41 passes through the dust removal box 1 through the entrance and exit 12. The transverse slide rail 43 passes through the dust removal box 1 through the entrance and exit 12. The two ends of the transverse slide rail 43 are respectively fixed to the two second limit blocks 40. The transverse slider 44 is arranged on the transverse slide rail 43. The transverse movement fixing block 45 is connected to the transverse slider 44. The transverse movement fixing block 45 is screwed to the second lead screw 41, and the longitudinal movement assembly 3 is installed thereon.

[0056] By rotating the second handwheel 42, the second lead screw 41 is driven to rotate synchronously. Since the second lead screw 41 is screwed to the transverse movement fixing block 45, the second lead screw 41 has a tendency to drive the transverse movement fixing block 45 to rotate synchronously. Due to the existence of the transverse slide rail 43 and the connection between the transverse movement fixing block 45 and the transverse slide rail 43 through the transverse slider 44, the transverse movement fixing block 45 is changed from a rotational movement to a linear movement along the axial direction of the second lead screw 41, thereby realizing the synchronous lateral movement of the longitudinal movement assembly 3 and the electromagnetic plate 2 along the axial direction of the second lead screw 41.

[0057] To achieve precise control of the lateral distance, refer to Figure 2 and Figure 4 As shown, a second counter 46 is also connected to the second lead screw 41. The second counter 46 rotates synchronously with the second lead screw 41 and starts counting when rotating. The counter value jumps according to the number of turns.

[0058] Furthermore, refer to Figure 2 and Figure 4 As shown, the transverse movement fixing block 45 includes a lead screw support 450 and a support plate 451. The support plate 451 is connected to the lead screw support 450, the longitudinal movement assembly 3, and the transverse slider 44. The lead screw support 450 is screwed to the second lead screw 41.

[0059] Refer to Figure 2 As shown, the support plate 451 includes a flat plate, a vertical plate, and a reinforcing plate. After the flat plate and the vertical plate are spliced, they are strengthened by the reinforcing plate. The longitudinal movement assembly 3 is installed on the flat plate.

[0060] Actually, the transverse movement fixing block 45 may include a support plate 451 to realize the installation of the longitudinal movement assembly 3.

[0061] It can be understood that the transverse movement fixing block 45 may also include a plurality of support plates 451. For example, referring to Figure 2 As shown, it includes three support plates 451. The middle support plate 451 is installed with the first mounting base plate 37, and each of the support plates 451 on both sides is installed with a longitudinal slide rail 38.

[0062] During the die-cutting process, the characteristics of each roll of material are inconsistent. It is necessary to observe manually and adjust the position of the separating device according to the actual situation. Such adjustments are usually short-distance adjustments, so it is more suitable to be adjusted through the handwheels of the longitudinal movement assembly 3 and the transverse movement assembly 4. When the electromagnetic plate 2 adsorbed with magnetic substances is sent into the dust removal box 1 and the distance moved during the return after dust removal is relatively long. Although it can be completed using the transverse movement assembly 4, it may be time-consuming and laborious for manual operation. Therefore, the present application provides a driving assembly to realize the operation of sending the electromagnetic plate 2 into the dust removal box 1 and returning after dust removal.

[0063] Specifically, referring to Figure 1 、 Figure 2 and Figure 5 As shown, a docking portion 410 is provided at the end of the second lead screw 41; the device further includes a driving assembly, and the driving assembly includes a connecting plate 47, a first driver 48 and a second driver 49. The first driver 48 has a docking rod 480 adapted to the docking portion 410. The first driver 48 is installed on the connecting plate 47 and is used to drive the docking rod 480 to drive the second lead screw 41 to rotate; the second driver 49 is connected to the connecting plate 47 and is used to drive the docking rod 480 of the first driver 48 to dock with or separate from the docking portion 410.

[0064] During use, the connecting plate 47 is driven by the second driver 49 to move, so as to drive the first driver 48 to move towards the second lead screw 41 until it stops when the docking rod 480 of the first driver 48 docks with the docking portion 410. Then, the second driver 49 is used to drive the docking rod 480 to rotate, thereby driving the second lead screw 41 to rotate until the electromagnetic plate 2 enters the dust removal box 1. After dust removal, the first driver 48 drives the docking rod 480 to reverse until it returns to its position. Then, the second driver 49 drives the connecting plate 47 to retreat until the docking rod 480 separates from the docking portion 410.

[0065] It can be understood that both the above-mentioned first driver 48 and second driver 49 can use motors, or the first driver 48 uses a motor and the second driver 49 uses a cylinder.

[0066] It can be understood that the above-mentioned docking portion 410 may be a docking port, and the docking port is a non-circular port, such as a semi-circular shape, a fan shape, a square shape, etc. Correspondingly, the docking rod 480 also adopts a semi-circular shape, a fan shape, a square shape, etc. to be inserted into the docking port.

[0067] Of course, non-circular docking interfaces such as semi-circular, sector-shaped, and square can also be provided on the docking rod 480, and the docking part 410 of the second lead screw 41 is semi-circular, sector-shaped, square, etc., so as to be inserted into the docking interface on the docking rod 480.

[0068] Furthermore, as shown in Figure 1 the figure, docking parts 410 are provided at both ends of the second lead screw 41, and each docking part 410 is configured with one of the driving components.

[0069] The advantage of using two driving components is that one of them drives the docking rod 480 to separate from the docking part 410, and the other drives the docking rod 480 to dock with the docking part 410, and their division of labor is clear.
