Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automation equipment, in particular to a coiled material finishing device. Background Art
[0002] When using the winding process to prepare coils, such as battery cells and capacitor cores, it is necessary to perform a finishing operation on the wound coils to prevent the coils from unraveling. For example, the core of a capacitor is wound with two layers of aluminum foil and multiple layers of PP film. After winding according to a fixed capacity, the layers of PP film must be bonded together by hot-welding to seal the tail end of the core. However, the hot-welding method has the risk of breaking the film material and wrinkling the film material, resulting in poor finishing effect. Utility Model Content
[0003] Based on this, it is necessary to provide a coil finishing device that improves the needle finishing effect to address the above problems.
[0004] A coil finishing device comprises a support, a driving member, a hot-joining member and a smoothing member, wherein the hot-joining member and the smoothing member are both installed on the support, the driving member can drive the smoothing member and the hot-joining member to move toward the coil to be finished, and make the smoothing member abut against the coil to be finished before the hot-joining member, and the hot-joining member can heat the coil it abuts against.
[0005] In one embodiment, the hot-scalding component includes a hot-scalding block and a heating rod embedded in the hot-scalding block, and the heating rod can heat the hot-scalding block.
[0006] In one embodiment, the hot-melt welding component further comprises a thermocouple embedded in the hot-melt welding block.
[0007] In one embodiment, the area where the hot stamping block contacts the coil to be finished is an arc surface.
[0008] In one of the embodiments, the smoothing member includes a smoothing seat and a smoothing roller. The smoothing roller is rotatably mounted on the smoothing seat and is used to abut against the coil to be finished.
[0009] In one embodiment, the smoothing member can elastically abut against the coil to be finished under the drive of the driving member.
[0010] In one embodiment, it also includes a rotating shaft rotatably mounted on the support, the ironing member and the smoothing member are both mounted on the rotating shaft, and the driving member can drive the rotating shaft to rotate around its own axis to drive the ironing member and the smoothing member to swing.
[0011] In one of the embodiments, a connecting block is provided on the rotating shaft, and the smoothing member is connected to the connecting block via an elastic member, and the elastic member can enable the smoothing member to elastically press against the coil to be finished.
[0012] In one embodiment, the elastic member is configured as a tension spring connected to the connecting block at one end and to the smoothing member at the other end, and the smoothing member is pressed against the connecting block under the action of the tension spring.
[0013] In one embodiment, a plurality of the hot-splicing parts are arranged at intervals along the extending direction of the rotating shaft.
[0014] In the above-mentioned coil finishing device, when finishing the coil, the driving member first drives the smoothing member and the ironing member to move toward the coil to be finished, until the smoothing member contacts the coil. As the coil continues to be wound, the smoothing member will gradually smooth the finishing end of the coil. After the finishing end of the coil reaches the hot-scalding position, the smoothing member and the coil remain in contact, and the driving member continues to drive until the ironing member contacts the finishing end of the coil, and the finishing end of the coil is hot-scalded and formed by heating. Since the finishing end is smoothed by the smoothing member before hot-scalding, and the smoothing member can remain in contact with the finishing end during the hot-scalding process, it can effectively prevent the finishing end from wrinkling and deforming during the hot-scalding process, thereby significantly improving the finishing effect.

[0025] See also Figure 1 The utility model provides a coiled material finishing device 100, which is used to finish a coiled material prepared by a winding process, such as a core of a battery or a capacitor. Specifically, the coiled material in this embodiment is a core 200 of a capacitor, and the core 200 is formed by winding two layers of aluminum foil and multiple layers of PP film on a winding shaft 300. The coiled material finishing device 100 is arranged on one side of the winding shaft 300, and is used to make the multiple layers of PP film at the end of the core 200 adhere to each other.
[0026] Please also read Figure 2 and Figure 3 The coil finishing device 100 in the preferred embodiment of the utility model includes a support 110, a driving member 120, a hot-joining member 130 and a smoothing member 140.
[0027] The support 110 plays a supporting role and can fix the coil finishing device 100 as a whole to one side of the winding shaft 300. The hot-joining piece 130 and the smoothing piece 140 are both installed on the support 110. The driving piece 120 can drive the smoothing piece 140 and the hot-joining piece 130 to move toward the coil to be finished, and make the smoothing piece 140 contact the coil to be finished before the hot-joining piece 130. The smoothing piece 140 and the hot-joining piece 130 can be driven by the same driving piece 120, or they can be driven separately by different driving pieces 120.
[0028] Specifically, in this embodiment, the smoothing member 140 and the hot-joining member 130 are driven by the same driving member 120, so the number of driving members 120 can be reduced, which is conducive to simplifying the structure of the coil finishing device 100. Moreover, the smoothing member 140 can be elastically abutted against the coil to be finished under the drive of the driving member 120.
[0029] On the one hand, the elastic abutment can improve the reliability of the abutment between the smoothing member 140 and the coil, thereby ensuring that the smoothing member 140 can always maintain abutment with the coil during the finishing process. On the other hand, the smoothing member 140 can float within a certain range through elastic deformation. In this way, when the driving member 120 continues to drive to make the hot-joining member 130 abut against the coil, the smoothing member 140 can maintain abutment with the coil and can float relative to the driving member 110, thereby avoiding interference with the action of the driving member 120.
[0030] The smoothing member 140 is generally in the shape of a long strip, extending in the extension direction of the winding shaft 300, and can smooth the coiled material it abuts. The hot-joining member 130 can heat the coiled material it abuts, thereby achieving hot-joining. When the coiled material, such as the core 300 of the capacitor, is finished, the driving member 120 first drives the smoothing member 140 and the hot-joining member 130 to move toward the core 300 until the smoothing member 140 abuts against the core 300. As the core 300 continues to be wound, the smoothing member 140 will gradually smooth the PP film at the end of the winding core 300. After the end of the core 300 reaches the hot-scalding position, the smoothing member 140 and the core 300 remain in contact, and the driving member 120 continues to drive until the hot-joining member 130 abuts against the end of the core 300, and heats the end of the core 300 until the multi-layer PP film is hot-stamped and adhered, thereby achieving the end. Since the tail end is smoothed by the smoothing member 140 before hot stamping, and the smoothing member 140 can maintain contact with the tail end during the hot stamping process, the tail end can be effectively prevented from wrinkling and deforming during the hot stamping process, thereby significantly improving the tailing effect.
[0031] In this embodiment, the smoothing member 140 includes a smoothing roller 142 of the smoothing seat 141, which is rotatably mounted on the smoothing seat 141 and is used to abut against the coil to be wound. During the continuous winding process of the winding shaft 200, the smoothing roller 142 can roll on the surface of the coil. In this way, the smoothing roller 142 has a better smoothing effect on the coil's tail end and is not easy to damage the film material at the tail end.
[0032] It should be noted that, in other embodiments, the smoothing member 140 may also be a long smoothing plate, and the area where the smoothing plate contacts the coil is configured to be an arc surface to avoid scratching the coil.
[0033] Please refer again Figure 1In this embodiment, the hot-seal component 130 includes a hot-seal block 131 and a heating rod 132 embedded in the hot-seal block 131 , and the heating rod 132 can heat the hot-seal block 131 .
[0034] The hot stamping block 131 is generally formed of a good heat conductor such as metal, and the heating rod 132 can be an electric ceramic heating rod, an electric heating wire heating rod, etc., which can be powered on to generate heat to heat the hot stamping block 131. The hot stamping block 131 is in direct contact with the coil, and can heat the tail end of the coil after the heating rod 132 heats up. It can be seen that the heating rod 132 does not directly heat the coil, but indirectly heats the tail end of the coil through the hot stamping block 131, so the risk of the hot stamping area being burned due to instantaneous excessive temperature can be reduced. In addition, the temperature distribution on the surface of the hot stamping block 131 is more uniform, so the hot stamping effect is further improved.
[0035] Furthermore, in this embodiment, the hot-welding member 130 further includes a thermocouple 133 embedded in the hot-welding block 131. The thermocouple 133 can monitor the temperature in the hot-welding block 131 in real time, thereby avoiding bad hot-welding caused by uncontrollable temperature factors.
[0036] In addition, in this embodiment, the area where the hot stamping block 131 contacts the coil to be finished is an arc surface. The arc surface can increase the contact area between the hot stamping block 131 and the coil end, thereby increasing the area of the hot stamping area to ensure the reliability of the hot stamping. Moreover, the arc surface contact area can also prevent the hot stamping block 131 from puncturing the coil end.
[0037] The hot-joint 130 in this embodiment can also be block-shaped, and each hot-joint 130 can form a block-shaped hot-joint area at the end of the coil. Multiple hot-joints 130 are arranged at intervals along the extension direction of the smoothing member 140, so multiple hot-joint areas can be formed at the end of the coil, and the end effect is better. In addition, the hot-joint 130 can be long and extend in the same direction as the smoothing member 140, so a long hot-joint area can be formed at the end of the coil.
[0038] Please refer again Figure 2 and Figure 3 In this embodiment, the coil finishing device 100 also includes a rotating shaft 150 rotatably mounted on the support 110, and the hot-splitting member 130 and the smoothing member 140 are both mounted on the rotating shaft 150. The driving member 120 can drive the rotating shaft 150 to rotate around its own axis to drive the hot-splitting member 130 and the smoothing member 140 to swing.
[0039] The rotating shaft 150 is substantially parallel to the winding shaft 200, and a plurality of hot-joining members 130 are arranged at intervals along the extending direction of the rotating shaft 150. The hot-joining members 130 and the smoothing members 140 can approach or move away from the coil to be wound up during the swinging process, and the hot-joining members 130 and the smoothing members 140 require less space for circular motion than for linear motion under the drive of the rotating shaft 150, so the space required for the coil winding device 100 can be reduced.
[0040] The driving member 120 may be a motor or a cylinder. Specifically, the driving member 120 in this embodiment is a cylinder, and is connected to the rotating shaft 150 through a connecting rod 180. One end of the connecting rod 180 is fixed to the rotating shaft 150, and the other end is fixed to the movable end of the cylinder. A hinge point is provided in the middle of the connecting rod 180. The cylinder can be extended and retracted to drive the connecting rod 180 to rotate around the hinge point and drive the rotating shaft 150 to rotate.
[0041] Furthermore, in this embodiment, a connecting block 160 is provided on the rotating shaft 150, and the smoothing member 140 is connected to the connecting block 160 through an elastic member 170. The elastic member 170 can make the smoothing member 140 elastically abut against the coiled material to be finished. When the smoothing member 140 abuts against the coiled material, the elastic member 170 generates elastic deformation and provides elastic force, so that the smoothing member 140 elastically abuts against the coiled material. The connecting block 160 provides an installation position for the elastic member 170 and the smoothing member 140, thereby facilitating installation. In addition, a plurality of connecting blocks 160 can be provided along the extension direction of the rotating shaft 150, so as to increase the stability of the smoothing member 140.
[0042] Furthermore, in the present embodiment, the elastic member 170 is configured as a tension spring having one end connected to the connecting block 160 and the other end connected to the smoothing member 140 , and the smoothing member 140 is pressed against the connecting block 160 under the action of the tension spring.
[0043] The smoothing member 140 is not directly connected to the connecting block, but is supported by the tension of the tension spring, which has a simpler structure and a higher floating range and degree of freedom of the smoothing member 140. In order to improve stability, two tension springs are provided for each connecting block 160, which are located on opposite sides of the connecting block 160.
[0044] It should be pointed out that in other embodiments, the elastic member 170 may also be a spring sheet with one end connected to the connecting block 160 and the other end connected to the smoothing member 140 .
[0045] In the coil finishing device 100, when finishing the coil, the driving member 120 first drives the smoothing member 140 and the hot-joining member 130 to move toward the coil to be finished, until the smoothing member 140 abuts against the coil. As the coil continues to be wound, the smoothing member 140 will gradually smooth the tail end of the coil. After the tail end of the coil reaches the hot-scalding position, the smoothing member 140 keeps abutting against the coil, and the driving member 120 continues to drive until the hot-joining member 130 abuts against the tail end of the coil, and the tail end of the coil is hot-scalded and formed by heating. Since the tail end is smoothed by the smoothing member 140 before hot-scalding, and the smoothing member 140 can keep abutting against the tail end during the hot-scalding process, it can effectively avoid the tail end from wrinkling and deforming during the hot-scalding process, thereby significantly improving the finishing effect.
[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0047] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
