Abstract
Description
Technical Field
[0001] This application relates to the field of battery technology, specifically to a reel, and also to a battery processing device for receiving the aforementioned reel. Background Technology
[0002] The current working principle of automatic positioning of rolls in battery processing equipment is as follows: When the take-up shaft of the battery processing equipment (such as a rolling mill) needs to load an empty roll, the material handling mechanism (OHT) picks up the roll placed on the roll tray. The material handling mechanism's material handling shaft aligns with the receiving roll, and then the material handling mechanism's pushing structure pushes the empty roll from the material handling shaft onto the take-up shaft. The take-up shaft tensions the inner wall of the roll, completing the automatic positioning of the empty roll. However, when the material handling mechanism's pushing structure pushes the empty roll, the empty roll will be propelled a certain distance by the pushing inertia, deviating from the target position where the roll needs to be connected with the material (such as an electrode sheet). This results in a high failure rate in battery processing equipment production, affecting normal production. Therefore, manual intervention is required to correct the roll's position and complete the roll positioning. Utility Model Content

[0020] A battery processing apparatus, comprising:
[0021] A reel, including a target position, for receiving a reel as described above;
[0022] The material pulling mechanism includes a snap-fit component and a first driving component.

[0045] a. Receiving groove. Detailed Implementation
[0046] This application provides a reel and battery processing equipment. The receiving section of the reel is located between the end plate and the middle part, and the radial dimension of the receiving section is smaller than the radial dimensions of the end plate and the middle part, thus forming a receiving groove a that is recessed inward along the radial direction. Due to the existence of the receiving groove a, it is possible to change the movement of the reel to the target position from pushing to pulling, and it can ensure that the pulling can be stopped and stopped at will, ensuring that the reel will not deviate from the target position under the action of inertial force. The position of the reel can be accurately positioned without manual intervention to correct it.
[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only one embodiment of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0048] like Figures 1-5 As shown, this application embodiment provides a reel including a middle portion 1 and two end heads 2 connected to the two axial ends of the middle portion 1. At least one of the two end heads 2 includes an end plate 21 and a receiving section 22. The receiving section 22 is located between the end plate 21 and the middle portion 1, and the outer diameter of the receiving section 22 is smaller than the outer diameter of the end plate 21 and the outer diameter of the middle portion 1, so as to form a receiving groove a that is recessed radially inward.
[0049] It should be noted that the materials of the middle part 1 and the end head 2 can be the same or different; the middle part 1 is made entirely of ABS material. Preferably, both end heads 2 include an end plate 21 and a receiving section 22, so as to form a receiving groove a at each end of the roll.
[0050] The end of the drum has a receiving groove a. Therefore, when the drum is fed onto the take-up shaft 71, it can be engaged with the receiving groove a by a snap-fit device. The snap-fit device pulls the receiving groove a, thereby moving the drum to the target position on the take-up shaft 71 where it needs to connect with the material, and then stopping it. Due to the existence of the receiving groove a, it is possible to change the movement of the drum from pushing to pulling, and it can ensure that the pulling can be stopped at any time. This ensures that the drum will not deviate from the target position under the action of inertial force. The drum can be accurately positioned without manual intervention to correct its position, thereby reducing the failure rate of the battery processing equipment and ensuring the normal production of the battery processing equipment.
[0051] Furthermore, when the operator manually picks up the roll, he holds the internal cavity of the roll (i.e., the inner wall of the roll) and the receiving groove a formed on the outer wall of the roll, so as to facilitate picking up the empty roll, picking up the roll with material on the single rod frame, and pulling the roll onto the single rod frame; the single rod frame can be the winding shaft 71 mentioned above, or it can be a material picking shaft, a winding unwinding shaft, or a tooling shaft, etc.
[0052] Optionally, the roll of material in this application is fed to the take-up shaft 71 of the battery processing equipment via a material handling mechanism 72. Specifically, the material handling mechanism 72 picks up the target roll from the roll placement tray, and then moves the target roll and feeds it to the take-up shaft 71. Further, the target roll is an empty roll of material to be wound. The battery processing equipment also includes a material pulling mechanism 73, whose latching member 731 engages with the receiving groove a of the roll, and pulls the receiving groove a to move the roll to the target position on the take-up shaft 71 where it needs to be connected with the material, thus completing the precise positioning of the roll. Optionally, the battery processing equipment can be equipment for processing the current collector, electrode, or separator of the battery; optionally, the battery processing equipment is a rolling mill, which is used to roll and compact the electrode after it has been coated with an active material layer; the material docked with the target position is the rolled and compacted electrode; the winding shaft 71 is an air-expanding shaft, which can tighten the inner wall of the drum, thereby driving the drum to rotate to wind up the electrode.
[0053] Please see the appendix Figure 2 In some embodiments of this application, the intermediate portion 1 includes a first half 11 and a second half 12 that are detachably spliced along the axial direction. One end head 2 is detachably connected to the end of the first half 11 away from the second half 12, and the other end head 2 is detachably connected to the end of the second half 12 away from the first half 11.
[0054] As mentioned above, the roll of this application includes at least four detachable and splicable components; when the roll is damaged by a collision, the operator only needs to disassemble the damaged part and replace the corresponding spare part to resume normal production; in this way, the entire roll can be scrapped, which not only saves material costs, but also reduces the frequency of replacing the entire roll and improves battery processing efficiency.
[0055] In some parallel embodiments, the roll is no longer a detachable, spliced structure composed of multiple components, but rather a non-detachable, one-piece molded structure.
[0056] Please see the appendix Figure 2 In some embodiments of this application, the intermediate portion 1 includes an outer peripheral member 13 and an inner peripheral member 14. The inner peripheral member 14 is sleeved inside the outer peripheral member 13, and an axially extending and penetrating receiving cavity 15 is formed in the gap between the outer peripheral member 13 and the inner peripheral member 14. The drum includes a reinforcing rod 3, which passes through the receiving cavity 15.
[0057] It should be noted that the reinforcing rod 3 is a steel rod structure, and the steel rod is made of carbon steel. The outer peripheral part 13 and the inner peripheral part 14 are adapted in shape; the specific shape of the outer peripheral part and the inner peripheral part 14 is not limited; preferably, both the outer peripheral part 13 and the inner peripheral part 14 are circumferential parts.
[0058] Since materials (such as electrode sheets) are wound into the middle section 1 of the roll, this section 1, as a stress-bearing area, experiences downward pressure, posing a risk of deformation or breakage during prolonged use. This application adds a reinforcing rod 3 within the middle section 1, which supports the middle section 1, increases its compressive strength, and prevents deformation or breakage. This improves the structural strength and load-bearing capacity of the roll, ensuring its stability during use, reducing the frequency of roll replacement, and minimizing waiting time for battery processing equipment.
[0059] Please see the appendix Figure 2-3 In some embodiments of this application, both end heads 2 are provided with first mounting holes 23 communicating with the accommodating cavity 15. Both ends of the reinforcing rod 3 are provided with second mounting holes 31; fasteners 4 are passed through the first mounting holes 23 and the second mounting holes 31 in sequence to fix the middle part 1 and the reinforcing rod 3 between the two end heads 2.
[0060] It should be noted that the first mounting hole 23 passes through the end plate 21 and the receiving section 22. Optionally, both the first mounting hole 23 and the second mounting hole 31 are threaded holes, and the fastener 4 is a screw or threaded rod with external threads.
[0061] As shown above, the middle part 1 and the reinforcing rod 3 are detachably connected and fixed between the two end heads 2. The assembly of these parts is simple, the assembly steps are simplified, and the operation is convenient and quick. When the drum is damaged by a collision, the operator only needs to remove the fastener 4 to easily and quickly remove the damaged part. The spare part corresponding to the damaged part is placed in the corresponding position and the fastener 4 is tightened to replace and install the spare part, so that the drum can be put into normal production.
[0062] Please see the appendix Figure 2 In some embodiments of this application, the outer peripheral member 13 and the inner peripheral member 14 are connected by a radially extending connector 16; a receiving cavity 15 is formed at the connector 16. It should be noted that the connector 16 has an axial extension length.
[0063] As described above, the connector 16 enables the connection, support and fixation of the outer peripheral part 13 and the inner peripheral part 14, and the connector 16 provides an attachment carrier for forming the accommodating cavity 15, so as to ensure the smooth installation of the reinforcing rod 3 and the support strength of the reinforcing rod 3.
[0064] Please see the appendix Figure 2 In some parallel embodiments, the middle part 1 is formed with a plurality of accommodating cavities 15 at circumferential intervals, and thus a plurality of reinforcing rods 3 are installed at circumferential intervals in the middle part 1.
[0065] It should be noted that the middle part 1 has 3-8 accommodating cavities 15 spaced apart along the circumference, so the middle part 1 is equipped with 3-8 reinforcing rods 3 spaced apart along the circumference; preferably, the middle part 1 has 6 accommodating cavities 15 spaced evenly along the circumference, so the middle part 1 is equipped with 6 reinforcing rods 3 spaced evenly along the circumference.
[0066] As mentioned above, under the premise of ensuring that the reinforcing rods 3 are not set too many times, it is possible to maintain the support and compressive strength of the middle part 1 of the drum within a reasonable range, avoid deformation or breakage of the middle part 1, and ensure the stability of the drum in use.
[0067] Please see the appendix Figure 4 In some embodiments of this application, the drum includes an extension portion 5, which can be detachably connected between the first half 11 and the second half 12 of the intermediate portion 1, and the number of extension portions 5 can be changed to adjust the axial length of the drum.
[0068] Please see the appendix Figure 1-2 When the drum does not require an extension of its axial length, the extension part 5 is not installed, meaning the number of extension parts 5 is 0; in this case, the first half 11 and the second half 12 are directly spliced together. Please refer to the appendix. Figure 4 When the axial length of the drum needs to be extended, an extension part 5 is connected between the first half 11 and the second half 12. Depending on the specific requirements, the number of extension parts 5 connected can be any one of 1, 2, 3, etc.
[0069] When the processing equipment is changed, the length of the material width will change accordingly (for example, after the roller press is changed, the width of the electrode will change accordingly), making the original axial length of the drum less than the length of the material width. Therefore, a certain number of extension parts 5 are added between the first half 11 and the second half 12 to extend the axial length of the drum to meet the length of the material width after the change.
[0070] Please see the appendix Figure 4-5 In some embodiments of this application, the first half 11 has a first groove extending axially and penetrating through it, the second half 12 has a second groove extending axially and penetrating through it, and the extension part 5 has a third groove 51 extending axially and penetrating through it. The two ends of the third groove 51 can communicate with the first groove and the second groove, respectively. The drum includes an extension rod 6, which can be detachably connected to the reinforcing rod 3 of the drum to sequentially receive the first groove, several third grooves 51, and the second groove, thereby realizing the connection of several extension parts 5 between the first half 11 and the second half 12.
[0071] It should be noted that the material of the reinforcing rod 6 can be the same as or different from that of the reinforcing rod 3; preferably, the reinforcing rod 6 is a steel rod structure made of carbon steel.
[0072] The addition rod 6 provides a receiving position for the connecting addition part 5, which facilitates the assembly and fixing of the addition part 5; at the same time, the addition rod 6 can ensure the support strength and compressive strength of the addition part 5, avoid deformation or breakage of the addition part 5, and thus ensure the stability of the drum.
[0073] In some embodiments, the adding rods 6 have different axial lengths; along the axial direction of the drum, an adding rod 6 of a specific axial length is selected to fit the number of adding parts 5 connected. As described above, regardless of how many adding parts 5 are added, only one adding rod 6 of a specific axial length can be connected along the axial direction of the drum to meet assembly requirements, simplifying the assembly process and saving effort. For example, the axial length of some adding rods 6 is exactly equal to the axial length of one adding part 5 to fit and connect one adding part 5; the axial length of some adding rods 6 is exactly equal to the sum of the axial lengths of two adding parts 5 to fit and connect two adding parts 5; the axial length of some adding rods 6 is exactly equal to the sum of the axial lengths of three adding parts 5 to fit and connect three adding parts 5; and so on.
[0074] In some parallel embodiments, the axial length of the increasing rod 6 is the same as the axial length of a single increasing part 5; along the axial direction of the drum, the same number of increasing rods 6 are selected to match the number of increasing parts 5 connected. As described above, the specifications of the increasing rods 6 are uniform, saving on the processing and manufacturing costs of the increasing rods 6.
[0075] In some parallel embodiments, the increasing rods 6 have different axial lengths; along the axis of the drum, several increasing rods 6 with different combinations of axial lengths are selected to match the number of connecting increasing parts 5. As described above, the specifications and forms of the increasing rods 6 are enriched, and they can be selected according to needs, making them flexible and practical.
[0076] It should be further noted that the number of additional rods 6 along the circumference of the drum is the same as the number of reinforcing rods 3.
[0077] Please see the appendix Figure 5 In some embodiments of this application, one end of the reinforcing rod 6 is provided with a connector 61 extending axially, and the other end is provided with a third mounting hole 62 that can be adapted to connect with the connector 61; the connector 61 can be connected to the second mounting hole 31 of the reinforcing rod 3.
[0078] Optionally, the outer surface of the connector 61 is provided with external threads, and the third mounting hole 62 and the second mounting hole 31 are both threaded holes.
[0079] As shown above, the detachable connection of the adding rod 6 to the reinforcing rod 3 and the detachable connection between adjacent adding rods 6 are realized, which facilitates disassembly, replacement and maintenance; and the third mounting hole 62 of the adding rod 6 can be assembled and fixed with the fastener 4 to fix the first half 11, several adding parts 5 and the second half 12 between the two end heads 2.
[0080] It should be noted that the side containing the first half of the roll 11 is the first side, and the side containing the second half is the second side.
[0081] When extending the axial length of the drum, the first half 11 and the first side end 2 can be kept in a fixed position, while the fasteners 4 on the second side can be loosened to remove the second side end 2 and the second half 12 from the reinforcing rod 3. Then, the adding rod 6 is connected to the reinforcing rod 3 to form a receiving rod. Then, a specific number of adding parts 5 are sequentially inserted into the receiving rod. Then, the second half 12 and the second side end 2 are installed. Finally, the fasteners 4 on the second side are sequentially tightened into the first mounting hole 23 of the second side end 2 and the third mounting hole 62 of the adding rod 6 to complete the fixed connection of the first half 11, the several adding parts 5, and the second half 12 between the two end 2.
[0082] Alternatively, when extending the axial length of the drum, keep the second half 12 and the second side end 2 fixed in position, while loosening the fastener 4 on the first side to remove the first side end 2 and the first half 11 from the reinforcing rod 3; please refer to the above for subsequent steps, which will not be repeated here.
[0083] Please see the appendix Figure 6-8 In summary, this application also discloses a battery processing apparatus, which includes a take-up shaft 71 and a feeding mechanism 73. The take-up shaft 71 includes a target position and is used to receive the roll as described above. Please refer to the appendix. Figure 8 The feeding mechanism 73 includes a latching member 731 and a first driving member 732. The latching member 731 can latch onto the receiving groove a of the drum. The first driving member 732 can drive the latching member 731 to move together with the drum, so that the drum is positioned at the target position.
[0084] It should be noted that the battery processing equipment can be equipment for processing the current collector, electrode sheet, or separator of the battery; optionally, the battery processing equipment is a rolling mill, which is used to roll and compact the electrode sheet after it has been coated with an active material layer; the material docked with the target position is the rolled and compacted electrode sheet; the winding shaft 71 is an air expansion shaft, which can tighten the inner wall of the winding drum, thereby driving the winding drum to rotate and wind up the electrode sheet.
[0085] Please see the appendix Figure 8Furthermore, the battery processing equipment includes a first fixing frame 74 for fixing the take-up shaft 71, which can be a fixing plate. The first driving member 732 is a linear driving member, which can be a guide rail slider structure, or any one of a telescopic electric cylinder, telescopic hydraulic cylinder, telescopic pneumatic cylinder, etc. Preferably, the first driving member is a guide rail slider structure, which includes a guide rail 7321, a slider 7322, and a linear servo motor 7324; the guide rail 7321 is fixed relative to the first fixing frame 74, for example, the guide rail 7321 can be directly fixed to the first fixing frame 74; the guide rail 7321 is parallel to the take-up shaft 71; under the drive of the linear servo motor 7324, the slider 7322 can be guided to move along the guide rail 7321. The snap-fit member 731 is fixed to the slider 7322 and moves along the guide rail 7321 under the drive of the slider 7322.
[0086] The battery processing equipment of this application includes a material pulling mechanism 73. The snap-fit component 731 of the material pulling mechanism 73 can be adapted to snap-fit into the receiving groove a of the roll. Therefore, when the roll is fed onto the take-up shaft 71, the snap-fit component 731 pulls the receiving groove a, thereby driving the roll to move to the target position on the take-up shaft 71 where it needs to dock with the material, and then stops. The movement of the roll to the target position is by pulling, and the pulling is stopped immediately, ensuring that the roll will not deviate from the target position under the action of inertial force. The roll position can be accurately positioned without manual intervention to correct the position, thereby reducing the failure rate of the battery processing equipment and ensuring the normal production of the battery processing equipment.
[0087] Please see the appendix Figure 8 In some embodiments of this application, the material pulling mechanism 73 further includes a second driving member 733, which can drive the snap-fit member 731 to rotate so that the snap-fit member 731 snaps into or unsnap into the receiving groove a of the roll.
[0088] It should be noted that the first driving component 732 also includes a support plate 7323, which is fixed to the slider 7322. Optionally, two guide rails 7321 are arranged side by side, and each guide rail 7321 is provided with a slider 7322; the support plate 7323 is fixed on all the sliders 7322. The second driving component 733 is fixed to the support plate 7323. Optionally, the second driving component 733 can be a crank-connecting rod structure that drives the snap-fit component 731 to rotate, or it can be a rotary motor, etc. Preferably, the second driving component 733 is a rotary motor, which is a rotary servo motor. The support plate 7323 has a through hole; the rotating shaft of the rotary motor passes through the through hole, and the rotating shaft is rotatably connected to the through hole through a bearing 734. The latching member 731 is an L-shaped latching member, which includes a horizontal rod parallel to the winding shaft 71 and a vertical rod perpendicular to the horizontal rod; the horizontal rod is connected to the rotating shaft of the rotary motor; the second driving member 733 drives the rotating shaft to rotate, which in turn drives the horizontal rod to rotate, and the horizontal rod to rotate, which in turn drives the vertical rod to rotate, so that the vertical rod is latched into or unlatched from the receiving groove a.
[0089] Furthermore, the second driving member 733 can drive the latching member 731 to rotate 90°, so as to drive the vertical rod to rotate to a position in the horizontal plane, at which time the vertical rod is latched in the receiving groove a; and can drive the vertical rod to rotate to a position in the vertical plane, at which time the vertical rod is released from the receiving groove a.
[0090] Please see the appendix Figure 7 In some embodiments of this application, the picking mechanism 72 picks up the target roll from the roll placement tray, and then the picking mechanism 72 drives the roll to move and feed it to the take-up shaft 71; the picking mechanism 72 can be a structure independent of the battery processing equipment, or it can be a component of the battery processing equipment. Further, the picking mechanism is an automatic OHT (i.e., overhead crane handling system).
