Description

Technical Field

[0001] The utility model relates to the technical field of conductive film production, in particular to a winding mechanism. Background Art

[0002] Conductive film is a polymer material with metal plated on the surface. It is widely used in lithium-ion batteries, and is mainly used as a battery current collector in lithium-ion batteries. When producing conductive film, the film is generally unwound by an unwinding mechanism, then electroplated by an electroplating mechanism to form a conductive film, and finally rewound by a rewinding mechanism.

[0003] The existing winding mechanism generally includes a winding core and an air-expanding shaft. The winding core is sleeved on the outer circumference of the air-expanding shaft. One end of the air-expanding shaft is connected to a driving mechanism. When the conductive film is wound, the winding core is first tightened by the air-expanding shaft, and then the air-expanding shaft is driven to rotate by the driving mechanism, thereby driving the winding core to rotate. The conductive film can be wound by the rotation of the winding core. In the process of winding the conductive film by the winding core, due to the heavy weight of the conductive film, the upper side of the winding core will be squeezed by the conductive film under the influence of the gravity of the conductive film, causing the winding core to rotate eccentrically during the rotation process, which makes it easy for the conductive film to be wrinkled or misaligned during the winding process.

It can be understood that the winding motor may not be set on the bottom of the first groove 231, for example, the winding motor is set on the winding frame.

[0048] In an alternative solution, the winding drive module includes a winding motor and a gear transmission assembly. The gear transmission assembly includes a driving gear and a driven gear, wherein the driving gear is sleeved on the outer periphery of the end of the output shaft of the winding motor, and the driven gear is sleeved on the outer periphery of one end of the winding core 10. The driven gear meshes with the driving gear. The winding motor is used to drive the driving gear to rotate, thereby driving the driven gear to rotate, and further driving the winding core 10 to rotate. The winding motor can be set on the bottom of the first groove 231 through a motor seat, and the driving gear and the driven gear are both located in the first groove 231. It can be understood that the winding motor may not be set on the bottom of the first groove 231, for example, the winding motor is set on the winding frame.

[0049] The bottom end of the fixed seat 21 and the bottom end of the first mounting plate 23 are used to be fixedly set on the winding frame. The bottom end of the movable seat 22 and the bottom end of the second mounting plate 24 are used to be slidably set on the winding frame through the linear slide rail module 50. Specifically, the linear slide rail module 50 includes a slide rail 51 and a slider 52 that slides with the slide rail 51. The bottom end of the movable seat 22 and the bottom end of the second mounting plate 24 are respectively provided with a first mounting groove 223 and a second mounting groove 244. The end of the slider 52 away from the slide rail 51 is arranged in the first mounting groove 223 and the second mounting groove 244. In this embodiment, there are two slide rails 51, and the two slide rails 51 are arranged front and back relative to each other. The number of sliders 52, the first mounting groove 223, and the second mounting groove 244 corresponds to the number of slide rails 51. It can be understood that the number of slide rails 51, sliders 52, the first mounting groove 223, and the second mounting groove 244 can be set according to actual conditions. The movable seat 22 and the second mounting plate 24 can move along the axial direction of the winding core 10 toward or away from the center of the winding core 10 through the linear slide rail module 50, that is, move left and right.

[0050] The second mounting plate 24 is used to be connected to the translation drive module, which includes, for example, a cylinder, which is arranged on the winding frame, and the end of the output shaft of the cylinder is connected to the second mounting plate 24, and the cylinder is used to drive the second mounting plate 24 and the movable seat 22 to move in a direction away from or close to the center of the winding core 10, that is, to move left and right, thereby driving the second clamping module to move in a direction away from or close to the center of the winding core 10. In actual application, after the conductive film is wound up, the corresponding inner gear ring 35 is first driven to rotate by the clamping driving member of the second clamping module, so that the corresponding multiple clamping plates 34 can be driven by the corresponding gear rack assembly to move in a direction away from the corresponding first bearing 11 to loosen the outer ring of the corresponding first bearing 11, and then the second mounting plate 24, the movable seat 22 and the second clamping module are driven by the cylinder to move in a direction away from the center of the winding core 10, so that the other end of the winding core 10 can be separated from the second mounting hole of the movable seat 22, and then the wound conductive film can be removed from the winding core 10.

[0051] Through the above structure, when actually winding, in the initial state, the multiple clamping plates 34 of the first clamping module and the multiple clamping plates 34 of the second clamping module respectively clamp the outer rings of the two first bearings 11, and under the rotation support of the two first bearings 11, the winding drive module can drive the winding core 10 to rotate relative to the fixed seat 21 and the movable seat 22, so that the conductive film can be wound through the winding core 10. After the conductive film is wound, the corresponding inner gear ring 35 is first driven to rotate by the clamping drive member of the second clamping module, so that the corresponding multiple clamping plates 34 can be driven to move away from the corresponding first bearing 11 through the corresponding gear rack assembly to loosen the outer ring of the corresponding first bearing 11, and then the second mounting plate 24, the movable seat 22 and the second clamping module are driven to move away from the center of the winding core 10 by the cylinder of the translation drive module, so that the other end of the winding core 10 can be separated from the second mounting hole of the movable seat 22, and then the wound conductive film is taken off from the winding core 10. After completion, the cylinder of the translation drive module drives the second mounting plate 24, the moving seat 22 and the second clamping module to move toward the center of the winding core 10, so that the other end of the winding core 10 can be re-inserted into the second mounting hole. Then, the clamping drive member of the second clamping module drives the corresponding inner gear ring 35 to rotate, so that the corresponding plurality of clamping plates 34 can be driven to move toward the direction close to the corresponding first bearing 11 through the corresponding gear rack assembly to clamp the outer ring of the corresponding first bearing 11.

[0052] When the winding core 10 needs to be replaced, the corresponding inner gear ring 35 is first driven to rotate by the clamping driving members of the first clamping module and the second clamping module respectively, so that the corresponding plurality of clamping plates 34 can be driven to move in a direction away from the corresponding first bearing 11 through the corresponding gear rack assembly to loosen the outer ring of the corresponding first bearing 11. Then, the cylinder of the translation driving module drives the second mounting plate 24, the moving seat 22 and the second clamping module to move in a direction away from the center of the winding core 10, so that the other end of the winding core 10 can be separated from the second mounting hole of the moving seat 22. Then, the driven pulley 41 sleeved on the outer periphery of one end of the winding core 10 is removed from the belt, and then the winding core 10 and the two first bearings 11 are removed from the fixed seat 21, and then one end of the new winding core 10 passes through the first mounting hole of the fixed seat 21 and the through hole 232 of the first mounting plate 23, and the belt is re-sleeved on the outer periphery of the driven pulley 41 on the outer periphery of one end of the new winding core 10. Then, the cylinder of the translation drive module drives the second mounting plate 24, the moving seat 22 and the second clamping module to move toward the center of the new core 10, so that the other end of the new core 10 can be inserted into the second mounting hole of the moving seat 22. Then, the clamping driving members of the first clamping module and the second clamping module respectively drive the corresponding inner gear ring 35 to rotate, so that the corresponding plurality of clamping plates 34 can be driven to move toward the direction of the corresponding first bearing 11 on the new core 10 through the corresponding gear rack assembly to clamp the outer ring of the corresponding first bearing 11, and the core 10 is replaced.

[0053] The utility model clamps the two first bearings 11 respectively by setting up a first clamping module and a second clamping module, so as to clamp the two ends of the winding core 10. In this way, when the winding core 10 is driven to rotate by the winding drive module to wind up the conductive film, the winding core 10 will not rotate eccentrically, thereby reducing wrinkles or misalignment of the conductive film during the winding process.

[0054] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
