Description

Technical Field

[0001] This utility model relates to the field of winding and packaging technology, and in particular to an aluminum strip winding device. Background Technology

[0002] Aluminum strip winding equipment is a key piece of equipment in battery component production, mainly used for winding and packaging aluminum strips (such as lithium battery casing encapsulation materials). During battery manufacturing, aluminum strips need to be wound into coils with high precision and efficiency to meet the requirements of subsequent stamping, slitting, and other processes. Traditional manual coil changing or single-station winding methods easily lead to production interruptions, affecting overall efficiency. Especially in high-speed automated production lines, continuous and uninterrupted winding operations have become a core requirement for increasing production capacity.

[0003] Currently, most common aluminum strip winding devices adopt a single winding reel design, which requires stopping the machine to replace the reel or manually switching the aluminum strip path, resulting in low production efficiency, high degree of manual intervention, and difficulty in achieving true seamless connection. Utility Model Content

[0004] The main purpose of this utility model is to propose an aluminum strip winding device, which aims to improve production efficiency and realize uninterrupted operation of aluminum strip winding and packaging.

[0005] To achieve the above objectives, this utility model proposes an aluminum strip winding device for winding and packaging aluminum strips; it includes a mounting plate, a frame, a winding assembly, a cutting assembly, and a rotating assembly;

[0006] The winding assembly includes a first take-up reel, a second take-up reel, a first auxiliary roller, a second auxiliary roller, a first drive member, and a second drive member; the first take-up reel and the second take-up reel are both disposed on the mounting plate, the first drive member is mounted on the mounting plate and is used to drive the first take-up reel to rotate; the second drive member is mounted on the mounting plate and is used to drive the second take-up reel to rotate; the first auxiliary roller and the second auxiliary roller are respectively disposed on the mounting plate and rotate in cooperation with the mounting plate;

[0007] The cutting assembly includes a third drive member and a cutting blade; the first take-up reel has a first cutting section, and the second take-up reel has a second cutting section; the third drive member is fixed to the frame, and the cutting blade is mounted on the drive end of the third drive member for cutting the aluminum strip; when the third drive member is driven, the cutting blade can enter the first cutting section or the second cutting section.

[0008] The rotating assembly is mounted on the frame and connected to the mounting plate; the rotating assembly is used to drive the mounting plate to rotate so that the first take-up reel and the second take-up reel can automatically exchange positions.

[0009] Specifically, in one working state, the first take-up reel is used for feeding the aluminum strip, the second take-up reel is used for winding and packaging the aluminum strip, and the first auxiliary roller is used to assist in the winding operation of the second take-up reel. When the second take-up reel completes the required winding thickness for aluminum strip winding and packaging, the cutter enters the first cutting section and cuts the aluminum strip. After cutting the aluminum strip, the first take-up reel performs winding and packaging. After the second take-up reel completes the unloading action, the rotating component drives the mounting plate to rotate so that the second take-up reel is used for feeding the aluminum strip, the first take-up reel is used for winding and packaging the aluminum strip, and the second auxiliary roller is used to assist in the winding operation of the first take-up reel.

[0010] In one specific embodiment, both the first cutting portion and the second cutting portion are sequentially formed with a first pressing surface, a cutting groove, and a second pressing surface, wherein the width of the first pressing surface is greater than that of the second pressing surface; after the cutter enters the cutting portion, the first pressing surface cooperates with the cutting groove to fix the aluminum strip, and the second pressing surface cooperates with the cutting groove to release the aluminum strip.

[0011] In one specific embodiment, the first and second pressing surfaces are provided with flexible adhesive layers. In another specific embodiment, the rotating assembly includes a rotary motor and a photoelectric switch; the mounting plate is provided with a limit identification element; the photoelectric switch is used to identify the limit identification element, and the rotary motor is signal-connected to the photoelectric switch to control the rotation of the rotary motor.

[0012] In one specific embodiment, the winding assembly further includes an adjusting rod disposed on the mounting plate and cooperating with the first auxiliary roller and / or the second auxiliary roller to adjust the relative height of the first auxiliary roller and / or the second auxiliary roller relative to the first take-up reel and / or the second take-up reel.

[0013] In one specific embodiment, the adjusting rod is threadedly engaged with the first auxiliary roller and the second auxiliary roller, and the adjusting rod has bidirectional threads, so that rotating the adjusting rod can simultaneously move the first auxiliary roller closer to or further away from it.

[0014] In one specific embodiment, a limiting component is also included. The limiting component is a pressure sensing switch, which is signal-connected to the third driving element. When the pressure sensing switch receives pressure from the aluminum strip, the pressure sensing switch can control the third driving element.

[0015] In one specific embodiment, a limiting component is also included, which includes a cylinder and a rolling roller. The cylinder is fixed to the frame, and the rolling roller is disposed at the drive end of the cylinder and alternately cooperates with the second winding reel or the first winding reel for lamination in the aluminum strip winding and packaging process.

[0016] This utility model's technical solution effectively solves the problems of low efficiency and discontinuous operation in traditional aluminum strip winding devices used in battery packaging applications by employing the coordinated operation of a mounting plate, winding assembly, cutting assembly, and rotating assembly. Specifically, the solution adopts a design where the first and second winding plates work alternately. The rotating assembly drives the mounting plate to rotate, achieving automatic station switching. The cutting assembly, in conjunction with the first or second cutting section on the winding plate, achieves precise cutting of the aluminum strip. This allows the second winding plate to immediately switch back to the first winding plate for continued operation. Simultaneously, the first and second auxiliary rollers ensure the stability of the winding process and control of the aluminum strip tension, thereby achieving continuous and uninterrupted winding and packaging, significantly improving production efficiency and avoiding downtime caused by manual intervention.

[0031] This utility model proposes an aluminum strip winding device 100, which aims to improve production efficiency and realize uninterrupted operation of aluminum strip winding and packaging.

[0032] Please see Figures 1 to 6 In one embodiment of the present invention, the aluminum strip winding device 100 includes a mounting plate 110, a frame 120, a winding assembly 130, a cutting assembly 140, and a rotating assembly.

[0033] The winding assembly 130 includes a first take-up reel 131, a second take-up reel 132, a first auxiliary roller 133, a second auxiliary roller 134, a first drive member 135, and a second drive member 136. The first take-up reel 131 and the second take-up reel 132 are both disposed on the mounting plate 110. The first drive member 135 is mounted on the mounting plate 110 and is used to drive the first take-up reel 131 to rotate. The second drive member 136 is mounted on the mounting plate 110 and is used to drive the second take-up reel 132 to rotate. The first auxiliary roller 133 and the second auxiliary roller 134 are respectively disposed on the mounting plate 110 and rotate in cooperation with the mounting plate 110.

[0034] The cutter assembly 140 includes a third drive member 141 and a cutter 142; a first take-up reel 131 has a first cutting section 1311, and a second take-up reel 132 has a second cutting section 1321; the third drive member 141 is fixed to the frame 120, and the cutter 142 is mounted on the drive end of the third drive member 141 for cutting aluminum strip; when the third drive member 141 is driven, the cutter 142 can enter the first cutting section 1311 or the second cutting section 1321;

[0035] The rotating assembly is mounted on the frame 120 and connected to the mounting plate 110; the rotating assembly is used to drive the mounting plate 110 to rotate so that the first take-up plate 131 and the second take-up plate 132 can automatically exchange positions.

[0036] Specifically, in one working state, the first take-up reel 131 is used for feeding aluminum strip, the second take-up reel 132 is used for winding and packaging aluminum strip, and the first auxiliary roller 133 is used to assist in the winding operation of the second take-up reel 132; when the second take-up reel 132 completes the required winding thickness for aluminum strip winding and packaging, the cutter 142 enters the first cutting section 1311 to cut the aluminum strip; after cutting the aluminum strip, the first take-up reel 131 performs winding and packaging; after the second take-up reel 132 completes the unloading action, the rotating component drives the mounting plate 110 to rotate, so that the second take-up reel 132 is used for feeding aluminum strip, the first take-up reel 131 is used for winding and packaging aluminum strip, and the second auxiliary roller 134 is used to assist in the winding operation of the first take-up reel 131.

[0037] It should be explained that the mounting plate 110 is the base structure for mounting the winding assembly 130. The mounting plate 110 can be a circular, square, or other shaped metal or composite material plate. The frame 120 is the main frame supporting the entire device, usually assembled by welding or bolting steel structures, and is used for mounting the cutter assembly 140. The winding assembly 130 includes a first take-up reel 131 and a second take-up reel 132, which are aluminum strip winding reels. They can adopt a metal roller structure with flanges. The first drive component 135 and the second drive component 136 can specifically be a servo motor, a stepper motor, or a hydraulic motor, etc.

[0038] The third drive component 141 of the cutter assembly 140 is preferably a linear cylinder, and the cutter 142 can be a tool made of carbide or high-speed steel. The rotating assembly includes a rotary motor 151, such as a worm gear motor or a direct drive motor, for driving the mounting plate 110 to rotate. The first cutting section 1311 and the second cutting section 1321 are specific groove-shaped structures opened on the first winding plate 131 and the second winding plate 132, respectively, and their first pressing surface 11a and second pressing surface 11c can be provided with a flexible layer of polyurethane or silicone; the first auxiliary roller 133 and the second auxiliary roller 134 refer to chrome-plated or rubber-coated guide mechanisms used for aluminum strip tension control.

[0039] More specifically, the first take-up reel 131 and the second take-up reel 132 are fixed to the mounting plate 110 via keyway or flange connection. The first drive unit 135 is directly connected to the shaft end of the first take-up reel 131 via a coupling, or through belt / gear transmission. The third drive unit 141 of the cutter assembly 140 is fixed to the frame 120 by bolts, and its drive end is connected to the cutter 142 via a thread or quick-release structure, allowing the cutter 142 to insert into the cutting section along a straight trajectory. The output shaft of the rotary motor 151 of the rotary assembly is coupled to the central rotating shaft of the mounting plate 110 via a reducer. The limit identification element 112 set on the edge of the mounting plate 110 cooperates with the photoelectric switch 152 to achieve angle positioning. The first auxiliary roller 133 and the second auxiliary roller 134 are adjustablely mounted on the side of the mounting plate 110 via bearing seats, and their height is adjusted by the adjusting rod 137 to adjust the tension control during the aluminum strip winding process.

[0040] In the specific working state, after the second take-up reel 132 completes winding, the mounting plate 110 remains stationary. The third drive component 141 pushes the cutter 142 to move, so that its blade is precisely aligned with the first cutting section 1311 of the first take-up reel 131 at the current station. At this time, the aluminum strip is fixed by the first cutting section 1311. After the cutter 142 completes the cut, it immediately retracts, and the first cutting section 1311 releases the end of the aluminum strip, ensuring that the first take-up reel 131 can smoothly grab the head of the aluminum strip after the station switch. This process is automated through the timing control of each component, avoiding the manual strip feeding step in traditional technology.

[0041] This embodiment of the invention effectively solves the problems of low efficiency and discontinuous operation of traditional aluminum strip winding devices 100 in battery packaging applications by employing the coordinated operation of mounting plate 110, winding assembly 130, cutting assembly 140, and rotating assembly. Specifically, the solution adopts a design where the first winding plate 131 and the second winding plate 132 work alternately. The rotating assembly drives the mounting plate 110 to rotate, realizing automatic switching of work positions. The cutting assembly 140, together with the first cutting part 1311 or the second cutting part 1321 on the winding plate, achieves precise cutting of the aluminum strip. This allows the second winding plate 132 to immediately switch back to the first winding plate 131 to continue operation after winding. At the same time, the first auxiliary roller 133 and the second auxiliary roller 134 are used to ensure the stability of the winding process and the control of aluminum strip tension, thereby achieving continuous and uninterrupted winding and packaging, significantly improving production efficiency and avoiding downtime caused by manual intervention.

[0042] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 In one specific embodiment, the first cutting part 1311 and the second cutting part 1321 are each sequentially formed with a first pressing surface 11a, a cutting groove 11b and a second pressing surface 11c. The width of the first pressing surface 11a is greater than that of the second pressing surface 11c. After the cutter 142 enters the cutting part, the first pressing surface 11a and the cutting groove 11b cooperate to fix the aluminum strip, and the second pressing surface 11c and the cutting groove 11b cooperate to release the aluminum strip.

[0043] Specifically, the cutting groove 11b is a V-shaped or U-shaped groove, and the groove depth is preferably 1.5-2 times the thickness of the aluminum strip. The varying widths are designed to provide different pressing forces. In operation, the first pressing surface 11a first contacts the aluminum strip; its wide design, combined with the flexible adhesive layer, generates sufficient static friction to position the aluminum strip. After the cutter 142 enters the cutting groove 11b and completes the cut, the narrow design of the second pressing surface 11c generates only a slight contact force, ensuring that the end of the aluminum strip can smoothly detach from the winding reel and avoiding feeding difficulties caused by adhesion.

[0044] Optionally, the first pressing surface 11a and the second pressing surface 11c are provided with flexible adhesive layers. When the cutter 142 is pushed into the cutting groove 11b by the third driving member 141, the wider design of the first pressing surface 11a, together with the flexible adhesive layer, generates greater friction to fix the aluminum strip, while the narrower second pressing surface 11c facilitates the aluminum strip to detach after cutting.

[0045] Specifically, the flexible adhesive layer refers to the elastic material layer bonded to the first pressing surface 11a or the second pressing surface 11c. It can be made of high-temperature resistant silicone rubber or polyurethane elastomer to balance cushioning and durability.

[0046] Please see Figure 2 and Figure 6 In a specific embodiment of this utility model, the rotating component includes a rotating motor 151 and a photoelectric switch 152; the mounting plate 110 is provided with a limit identification element 112; the photoelectric switch 152 is used to identify the limit identification element 112, and the rotating motor 151 is signal-connected to the photoelectric switch 152 to control the rotation of the rotating motor 151.

[0047] In this embodiment, the closed-loop control of photoelectric switch 152 and rotary motor 151 has significant advantages over the traditional mechanical stop positioning method: the non-contact detection method of photoelectric switch 152 makes the positioning process wear-free and the braking precise, thereby ensuring the stability of workstation changes.

[0048] Please see Figure 1 and Figure 6 In one embodiment, the winding assembly 130 further includes an adjusting rod 137, which is disposed on the mounting plate 110 and cooperates with the first auxiliary roller 133 and / or the second auxiliary roller 134 to adjust the relative height of the first auxiliary roller 133 and / or the second auxiliary roller 134 relative to the first take-up reel 131 and / or the second take-up reel 132.

[0049] Specifically, the adjusting rod 137 refers to the mechanical component used to adjust the height of the first auxiliary roller 133 and / or the second auxiliary roller 134, and can be a two-way threaded screw or a precision ball screw with positive and negative threads. The adjustment range can be set to accommodate the winding requirements of aluminum strips with different thicknesses and tensions.

[0050] In one specific embodiment, the adjusting rod 137 is threadedly engaged with the first auxiliary roller 133 and the second auxiliary roller 134. The adjusting rod 137 has bidirectional threads, and rotating the adjusting rod 137 can simultaneously move the first auxiliary roller 133 closer to or further away from it. This achieves symmetrical adjustment of the aluminum strip tension.

[0051] In one embodiment of this utility model, a limiting component 160 is also included. The limiting component 160 is a pressure sensing switch. The pressure sensing switch is signal-connected to the third driving component 141. When the pressure sensing switch receives the pressure of the aluminum strip, the pressure sensing switch can control the third driving component 141.

[0052] Specifically, the pressure detection method directly reflects the actual thickness of the roll material, controls it with high precision, and is suitable for the precision winding of ultra-thin battery aluminum strips.

[0053] Please see Figure 3 and Figure 4 In another specific embodiment, the limiting component 160 includes a cylinder 161 and a roller 162. The cylinder 161 is fixed to the frame 120, and the roller 162 is disposed at the drive end of the cylinder 161 and alternately cooperates with the second winding reel 132 or the first winding reel 131 for lamination in the aluminum strip winding and packaging process.

[0054] Understandably, the setting of the roller 162 is suitable for the precision winding of aluminum strip, which reduces the bubble defect rate of the aluminum strip winding disc and improves the neatness of the coil end face.

[0055] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
