Description

Technical Field

[0001] This application relates to the field of electronic component manufacturing equipment technology, and in particular to a fully automatic guide pin winding machine. Background Technology

[0002] In the field of electronic component manufacturing equipment technology, especially in capacitor pin winding processing equipment, fully automatic large-scale pin winding machines are required. They are widely used in the production of energy storage devices such as batteries and capacitors, and are one of the core equipment indispensable for the large-scale production of lithium batteries, supercapacitors and other products. They are used to wind electrode sheets (positive electrode sheets, negative electrode sheets) and separators into cells with pins as the axis according to a preset process.

[0003] The patented fully automatic nailing and winding machine with reference application number CN201980000410.7 uses a reversing seat to switch cyclically between the needle winding station, the adhesive application station, and the material picking station. This method requires switching between multiple stations during the switching process, which consumes more switching time and winding time, thereby reducing the winding speed and affecting the overall winding efficiency. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a fully automatic guide pin winding machine.

[0005] The fully automatic guide pin winding machine provided in this application adopts the following technical solution: A fully automatic guide pin winding machine includes a frame providing support and installation space, with several guide rollers on the frame. The frame also includes a media feeding mechanism, a winding mechanism, a cutting mechanism, and a recovery robot. The media feeding mechanism feeds negative foil, positive foil, first release paper, and second release paper to the winding mechanism. The winding mechanism winds the negative foil, positive foil, first release paper, and second release paper to form capacitor elements. The cutting mechanism cuts the wound capacitor elements, which are then gripped and recovered by the recovery robot. The winding mechanism includes a switching drum, a drive unit, and a needle winding assembly. A first station and a second station are located in front of the switching drum. The switching drum has two mounting ports, each pivotally connected to a needle winding assembly. The drive unit is connected to the frame, and the needle winding mechanism has a first linkage assembly connected to the drive unit. The drive unit drives the switching drum to rotate 180° via the first linkage assembly, simultaneously rotating the two needle winding assemblies 180°. The two needle winding assemblies switch to their respective stations through rotation, with the first and second stations providing different processing actions.

[0006] By adopting the above technical solution, the dielectric materials such as negative foil, positive foil, first release paper and second release paper are transported to the winding mechanism by the dielectric feeding mechanism. The dielectric materials are wound at the first station of the winding mechanism. After the cutting mechanism cuts the dielectric materials, the driving component drives the switching cylinder and two sets of winding needle assemblies to rotate 180° between the first station and the second station through the first linkage component, switching the position of the winding needle assembly so that the wound capacitor element rotates to the second station. The second station is used for adhesive application, while the other set of winding needle assemblies returns to the first station for winding. This achieves the two sets of stations to be staggered and synchronized, thereby improving the overall winding and processing efficiency.

[0007] Optionally, the media feeding mechanism includes a negative foil feeding assembly, a first release paper feeding assembly, a second release paper feeding assembly, a positive foil feeding assembly, a negative stapler assembly, and a positive stapler assembly. The negative foil feeding assembly contains a negative foil, which is conveyed to the winding mechanism via a guide roller along a first path. The negative stapler assembly is located on one side of the negative foil feeding assembly and on the first path. It punches holes in the negative foil, feeds and staples guide pins into the negative foil, flattens it, and continues to convey it to the winding mechanism. The first release paper feeding assembly conveys the first release paper to the winding mechanism via a guide roller along a second path, and the second release paper feeding assembly conveys the second release paper to the winding mechanism via a guide roller along a third path. The positive foil feeding assembly contains a positive foil, which is conveyed to the winding mechanism via a guide roller along a fourth path. The positive stapler assembly is located on one side of the positive foil feeding assembly and on the fourth path. It punches holes in the positive foil, feeds and staples guide pins into the positive foil, flattens it, and continues to convey it to the winding mechanism.

[0008] By adopting the above technical solution, the negative foil feeding component conveys the negative foil, and the positive foil feeding component conveys the positive foil. During the conveying process, the positive nailing component and the negative nailing component convey the guide nails and nail them into the foil to become the electrode lead-out end of the capacitor element, thereby realizing current conduction. The first and second isolation paper are conveyed by the first isolation paper feeding component and the second isolation paper feeding component to separate the positive and negative electrodes and form the necessary covering structure of the capacitor element.

[0009] Optionally, all four paths can be synchronous and at a constant speed.

[0010] By adopting the above technical solution, the positive foil, negative foil, first isolation paper and second isolation paper are transported synchronously and at the same speed through the first to fourth paths, ensuring that the dimensions of the positive foil, negative foil, first isolation paper and second isolation paper are the same after the capacitor element is formed.

[0011] Optionally, the first linkage component includes a drive shaft and a first pivot gear; one end of the drive shaft is connected to the drive component, and the other end is connected to the switching cylinder; the first pivot gear is provided in two sets, which are installed sequentially at a preset distance at the end of the drive shaft near the switching cylinder.

[0012] By adopting the above technical solution, the driving component drives the driving shaft to rotate, and the two sets of first pivot gears on the driving shaft rotate synchronously. The first pivot gears drive the two sets of needle winding assemblies to rotate, so that when the driving shaft drives the switching cylinder to rotate, the two sets of needle winding assemblies rotate synchronously along the mounting port.

[0013] Optionally, the needle winding assembly includes a needle winding cylinder, a needle winding section, a first push-pull section, a second push-pull section, and a second pivot gear; the needle winding cylinder is connected to the mounting port, the second pivot gear is mounted on the outer wall of the needle winding cylinder and meshes with the first pivot gear; the needle winding section is inserted into the needle winding cylinder and moves along the length direction of the needle winding cylinder; the first push-pull section and the second push-pull section are both mounted on the needle winding section, and the interval between the first push-pull section and the second push-pull section is a push-pull opening.

[0014] By adopting the above technical solution, the needle winding cylinder follows the first pivot gear to rotate along the mounting port using the second pivot gear, thereby driving the needle winding part to rotate. The needle winding part provides the winding of the medium material. After the winding is completed, the rotation of the needle winding part can prevent the adhesion of the medium material after it is cut. At the same time, a first push-pull part and a second push-pull part are provided. The push-pull port between the first push-pull part and the second push-pull part forms a fulcrum that can push the needle winding part out of the needle winding cylinder or push the needle winding cylinder back.

[0015] Optionally, the winding mechanism further includes a second linkage component, a pusher component, and a return component; the pusher component and the return component are fixed in position and are located on the rotation path of the two winding components respectively, and the position of the pusher component corresponds to the first station and the position of the return component corresponds to the second station; the second linkage component is connected to the switching cylinder and is connected to the pusher component and the return component.

[0016] By adopting the above technical solution, the connection between the second linkage component and the switching cylinder enables the first linkage component to drive the switching cylinder to rotate, which in turn drives the second linkage component. This causes the second linkage component to drive the needle push component to push the needle winding part out of the needle winding cylinder at the first station, and the needle return component to pull the needle winding part back into the needle winding cylinder at the second station, thereby achieving the driving effect on the needle winding component.

[0017] Optionally, the second linkage assembly includes a linkage gear ring, a first linkage gear, a divider, a second linkage gear, a third linkage gear, a linkage belt, a bearing housing, a linkage shaft, an eccentric wheel, a hinge frame, a hinge shaft, and a push frame; the linkage gear ring is fixed to the outer wall of the switching cylinder; the divider is mounted on the frame, the first linkage gear is mounted on the divider and meshes with the linkage gear ring; the second linkage gear is connected to the other end of the divider; two sets of bearing housings are provided, and a linkage shaft is pivotally connected between the two sets of bearing housings; the third linkage gear is mounted on the linkage shaft, and a linkage belt is sleeved between the second and third linkage gears; two sets of eccentric wheels are provided, installed on the linkage shaft at a preset distance; the hinge frame is connected to the eccentric wheel, and a hinge shaft is hinged to the other end of the hinge frame; the push frame is connected to the hinge shaft to provide intermediate pushing action, and the push needle assembly and the return needle assembly are each connected to a set of push frames.

[0018] By adopting the above technical solution, the linkage gear ring follows the rotation of the switching cylinder to synchronously drive the first linkage gear, the divider, the second linkage gear, the linkage belt, and the third linkage gear to rotate, thereby realizing the rotation of the linkage shaft along the bearing seat. Two sets of eccentric wheels are set on the linkage shaft to rotate. Through the hinge frame, the hinge shaft, and the push frame, the push frame drives the push needle assembly to perform the push needle action or the return needle assembly to perform the return needle action, without the need for additional drive components, thus improving the overall linkage.

[0019] Optionally, the pusher assembly and the return assembly have the same structure, but the positions of the pusher assembly and the return assembly are different, as are the driving points corresponding to the second linkage assembly. When the pusher assembly is pushed by the pusher frame, it pushes the winding part located at the first station out of the winding cylinder. When the return assembly is pushed by the pusher frame, it pushes the winding part located at the second station back into the winding cylinder.

[0020] By adopting the above technical solution, the push needle assembly and the return needle assembly have the same structure but different directions of action due to the different driving points corresponding to the second linkage components. The push needle assembly pushes the winding needle part out of the winding needle cylinder, and the return needle assembly pushes the winding needle part back into the winding needle cylinder, so as to realize the winding and separation of the medium material.

[0021] Optionally, the pusher assembly includes a pusher frame, a fixed rail, a sliding block, and a pusher part; the pusher frame is pivotally connected to the pusher frame; the fixed rail is installed on the top of the divider, the sliding block is slidably connected to the fixed rail, the pusher part is installed on the sliding block, and when the needle winding assembly rotates to the first station, the pusher part is located in the push-pull opening.

[0022] By adopting the above technical solution, when the needle winding assembly follows the first station, the push-pull port between the first push-pull part and the second push-pull part is inserted with the needle pusher part. The divider is used to make the pusher frame intermittently push the needle pusher frame, so that the needle pusher frame drives the sliding block and the needle pusher part to move along the fixed rail, thereby causing the needle pusher part to push the first push-pull part and the needle winding part to extend out of the needle winding cylinder.

[0023] Optionally, the drive shaft extends through the switching cylinder to the end away from the drive component, and this end is also provided with an abutment cover. When the needle winding part extends out of the needle winding cylinder, the needle winding part abuts against the abutment cover.

[0024] By adopting the above technical solution, the function of the abutment cover is to limit the winding position of the dielectric material during winding, prevent the dielectric material from detaching from the winding needle part during winding, block the detachment path of the dielectric material, and play a role in preventing detachment. At the same time, the abutment cover rotates with the drive shaft to ensure that the capacitor element will not fall out of the winding needle part after winding is completed.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The dielectric material, including negative foil, positive foil, first release paper, and second release paper, is fed to the winding mechanism by the dielectric feeding mechanism. The dielectric material is wound at the first station of the winding mechanism. After the cutting mechanism cuts the dielectric material, the driving component drives the switching cylinder and two sets of winding needle assemblies to rotate 180° between the first station and the second station through the first linkage component. This switches the position of the winding needle assembly, causing the wound capacitor element to rotate to the second station. The second station is used for adhesive application, while the other set of winding needle assemblies returns to the first station for winding. This achieves staggered and synchronous operation of the two sets of stations, thereby improving the overall winding and processing efficiency. 2. The negative foil feeding assembly feeds the negative foil, and the positive foil feeding assembly feeds the positive foil. During the feeding process, the positive and negative nailing assemblies feed the guide nails and nail them into the foil to become the electrode leads of the capacitor element, realizing current conduction. The first and second isolation paper feeding assemblies feed the first and second isolation paper to separate the positive and negative electrodes, forming the necessary covering structure of the capacitor element. 3. The positive foil, negative foil, first isolation paper and second isolation paper are synchronously and uniformly conveyed using the first to fourth paths respectively to ensure that the dimensions of the positive foil, negative foil, first isolation paper and second isolation paper are the same after the capacitor element is formed; 4. The driving component drives the drive shaft to rotate, and the two sets of first pivot gears on the drive shaft rotate synchronously. The first pivot gears drive the two sets of needle winding assemblies to rotate, so that when the drive shaft drives the switching cylinder to rotate, the two sets of needle winding assemblies rotate synchronously along the mounting port.

Furthermore, when it is said that a device "comprises" a certain constituent element, unless otherwise stated otherwise, this does not exclude other constituent elements, but rather implies that other constituent elements may be included.

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0033] This application discloses a fully automatic guide pin winding machine.

[0034] A fully automatic guide pin winding machine, reference Figure 1 and Figure 2 As shown, the device includes a frame 1, which provides support and installation space. The frame 1 is equipped with several guide rollers 11, which guide and convey the medium material. The frame 1 is also equipped with a CCD inspection camera, a guide needle positioning and adjustment assembly, a needle flipping assembly, an embossing assembly, a random needle detection assembly, a dust suction assembly, a post-nail brush assembly, a controller, etc. These are not related to the technical issues and will not be described in detail here.

[0035] The frame 1 is equipped with a medium feeding mechanism 2, a winding mechanism 3, a cutting mechanism 4, and a recycling robot 5. The medium material is a negative foil, a positive foil, a first release paper, and a second release paper. The negative foil and the positive foil are also called negative electrode foil and positive electrode foil. The winding medium material roll is loaded onto the medium feeding mechanism 2. The medium feeding mechanism 2 conveys the negative foil, the positive foil, the first release paper, and the second release paper to the winding mechanism 3 respectively.

[0036] The winding mechanism 3 winds the negative foil, positive foil, first release paper, and second release paper to form a capacitor element. The cutting mechanism 4 cuts the wound capacitor element. The cutting mechanism 4 includes an upper cutter and a lower cutter arranged opposite each other in the vertical direction. Driven by a cylinder or other driving element, they move relative to each other in the vertical direction and intersect at the winding completion point of the winding mechanism 3, thereby cutting the wound capacitor element. Then, the recycling robot 5 clamps it to the recycling point for unified collection.

[0037] The winding mechanism 3 includes a switching cylinder 31, a driving component 32, and a winding needle assembly 33. There are a first station and a second station in front of the switching cylinder 31. The first station provides winding, and the second station provides adhesive application. The positions of the two stations remain unchanged. The driving component 32 can be a drive motor to drive the rotation of the switching cylinder 31 and the winding needle assembly 33. The switching cylinder 31 is pivotally connected to the frame 1.

[0038] The switching cylinder 31 has two mounting ports, and each mounting port is pivotally connected to a needle winding assembly 33. The driving component 32 is connected to the frame 1. The needle winding mechanism is provided with a first linkage component 34, which is connected to the driving component 32. The switching cylinder 31 can rotate to switch different needle winding assemblies 33 to the first and second work positions for winding and applying adhesive.

[0039] The driving component 32 drives the switching cylinder 31 to rotate 180°, which in turn drives the two sets of needle winding assemblies 33 to rotate 180°. During the rotation, the two sets of needle winding assemblies 33 rotate synchronously. The two sets of needle winding assemblies 33 switch to their respective work stations by rotating. When one set of needle winding assemblies 33 rotates to the first work station, it is wound by the first work station. After winding and forming, it rotates to the second work station, where it is glued, thereby realizing the dual-work station switching winding process.

[0040] Specifically, the dielectric material, including negative foil, positive foil, first release paper, and second release paper, is fed to the winding mechanism 3 by the dielectric feeding mechanism 2. The dielectric material is wound at the first station of the winding mechanism 3. After the cutting mechanism 4 cuts the dielectric material, the driving component 32 drives the switching cylinder 31 and the two sets of winding needle assemblies 33 to rotate 180° between the first station and the second station through the first linkage component. This switches the position of the winding needle assembly 33, causing the wound capacitor element to rotate to the second station. The second station is used for adhesive application, while the other set of winding needle assemblies 33 returns to the first station for winding. This achieves staggered and synchronous winding and adhesive application, thereby improving the overall winding and processing efficiency.

[0041] Further reference Figure 1As shown, the medium feeding mechanism 2 includes a negative foil feeding assembly 21, a first release paper feeding assembly 22, a second release paper feeding assembly 23, a positive foil feeding assembly 24, a negative nailing machine assembly 25, and a positive nailing machine assembly 26. The negative foil feeding assembly 21 is fitted with a negative foil roll, and the negative foil is conveyed to the winding mechanism 3 along the first path via the guide roller 11. The positive foil feeding assembly 24 has the same structure as the negative foil feeding assembly 21, except that the material conveyed is positive foil and the installation position is different. The positive foil feeding assembly 24 is fitted with positive foil, and the positive foil is conveyed to the winding mechanism 3 along the fourth path via the guide roller 11.

[0042] The negative nailing machine assembly 25 and the positive nailing machine assembly 26 have the same structure. The positive nailing machine assembly 26 is located on one side of the positive foil feeding assembly 24 and on the fourth path. It punches holes in the positive foil, feeds and nails the guide pins into the positive foil, and flattens it before continuing to feed it to the winding mechanism 3. The negative nailing machine assembly 25 is located on one side of the negative foil feeding assembly 21 and on the first path. It punches holes in the negative foil, feeds and nails the guide pins into the negative foil, and flattens it before continuing to feed it to the winding mechanism 3. Both the positive nailing machine assembly 26 and the negative nailing machine assembly 25 are fed by a vibratory feeder and then nailed into the foil. Subsequently, a brush is provided to clean the debris on the surface of the positive or negative foil, and a dust suction assembly simultaneously removes dust. Then, the negative foil is flattened so that it enters the first path, and the positive foil enters the fourth path for continued feeding.

[0043] The first release paper feeding assembly 22 feeds the first release paper to the winding mechanism 3 via the guide roller 11 along the second path, and the second release paper feeding assembly 23 feeds the second release paper to the winding mechanism 3 via the guide roller 11 along the third path. The first release paper and the second release paper are used to separate the positive foil and the negative foil respectively, so that the two will not come into direct contact during winding.

[0044] Among them, the first to fourth paths are all synchronous and at a constant speed, so that the positive foil, negative foil, first isolation paper and second isolation paper are all synchronously transported and wound, ensuring that the positive foil, negative foil, first isolation paper and second isolation paper are all the same size after the capacitor element is formed.

[0045] The negative foil feeding component 21, the first isolation paper feeding component 22, the second isolation paper feeding component 23, and the positive foil feeding component 24 included in the medium feeding mechanism 2 are all existing structures, and their specific structures will not be described in detail here.

[0046] Specifically, the negative foil feeding assembly 21 feeds the negative foil, and the positive foil feeding assembly 24 feeds the positive foil. During the feeding process, the positive nailing assembly 26 and the negative nailing assembly 25 feed the guide nails and nail them into the foil to become the electrode leads of the capacitor element, thereby realizing current conduction. The first isolation paper feeding assembly 22 and the second isolation paper feeding assembly 23 feed the first isolation paper and the second isolation paper to separate the positive and negative electrodes and form the necessary covering structure of the capacitor element.

[0047] Furthermore, tensioning components are also provided on the first to fourth paths. These tensioning components provide tension for the conveying of the positive foil, negative foil, first release paper, and second release paper on the first to fourth paths. The tensioning components may include a tensioning drive source, such as a cylinder. A pressure sensor is provided on the surface of the tensioning drive source. A pivoting roller is connected to the pressure sensor. The roller contacts the medium material, and the medium material is conveyed along the roller. During the conveying process, according to the pressure change detected by the pressure sensor, the tensioning drive source adjusts its position by extending or contracting, thereby changing the tension effect on the medium material and realizing the function of constantly adjusting the tension of the medium material during the conveying process.

[0048] In some embodiments, reference Figure 3 As shown, the first linkage component 34 includes a drive shaft 341, a first pivot gear, and a linkage gear ring 351. One end of the drive shaft 341 is connected to the drive member 32, and the other end is connected to the switching cylinder 31. The switching cylinder 31 is pivotally connected to the frame 1, that is, the frame 1 can have a pivot port for the switching cylinder 31 to pivotally connect, or a pivot bearing can be provided so that the switching cylinder 31 can rotate along the frame 1, so that the position of the installation port can be switched when the drive member 32 drives the switching cylinder 31 to rotate. When the connection process of the drive shaft 341 is long, a drive shaft 341 bearing can be set in the middle to provide partial load bearing.

[0049] Two sets of first pivot gears are installed sequentially at a preset distance on one end of the drive shaft 341 near the switching cylinder 31. When the drive shaft 341 is driven by the drive member 32, it drives the two sets of first pivot gears to rotate. The two sets of first pivot gears are used to provide rotation for the needle winding assembly 33, so that the needle winding assembly 33 can rotate with it. This can prevent the cutting mechanism 4 from cutting the dielectric material and leaving the dielectric material attached or sticking to the formed capacitor element.

[0050] Specifically, the drive unit 32 drives the drive shaft 341 to rotate, and the two sets of first pivot gears on the drive shaft 341 rotate synchronously. The first pivot gears drive the two sets of needle winding assemblies 33 to rotate, so that when the drive shaft 341 drives the switching cylinder 31 to rotate, the two sets of needle winding assemblies 33 rotate synchronously along the mounting port.

[0051] Further reference Figure 2 and Figure 3As shown, the needle winding assembly 33 includes a needle winding cylinder 331, a needle winding section 332, a first push-pull section 333, a second push-pull section 334, and a second pivot gear 335. The needle winding cylinder 331 is connected to the mounting port by a pivot connection. The second pivot gear 335 is mounted on the outer wall of the needle winding cylinder 331 and meshes with the first pivot gear. The second pivot gears 335 of the two sets of needle winding assemblies 33 are in different positions and are set at a preset distance from each other. Therefore, the two sets of second pivot gears 335 correspond to the two sets of first pivot gears respectively, so that the two sets of pivot gears on the drive shaft 341 can independently provide rotation to their respective second pivot gears 335.

[0052] The needle winding section 332 is inserted into the needle winding cylinder 331 and moves along the length of the needle winding cylinder 331. The needle winding section 332 provides winding of dielectric material. The needle winding section 332 moves along the needle winding cylinder 331, extending out of the needle winding cylinder 331 or retracting the needle winding cylinder 331. When the needle winding cylinder 331 is extended, the dielectric material can be wound along the needle winding section 332. When the needle winding cylinder 331 is retracted, the recovery robot 5 clamps the wound dielectric material, i.e., the capacitor element, and can then be recovered.

[0053] The first push-pull part 333 and the second push-pull part 334 are both installed on the needle winding part 332, and the interval between the first push-pull part 333 and the second push-pull part 334 is a push-pull opening 336. The first push-pull part 333 and the second push-pull part 334 have the same structure and can both adopt a circular plate structure. The push-pull opening 336 is formed between the two circular plate structures. When the needle winding cylinder 331 rotates, the push-pull opening 336 rotates accordingly.

[0054] Specifically, the needle winding cylinder 331 rotates along the mounting port with the first pivot gear via the second pivot gear 335, thereby driving the needle winding part 332 to rotate. The needle winding part 332 provides the winding of the medium material. After the winding is completed, the rotation of the needle winding part 332 can prevent the adhesion of the medium material after it is cut. At the same time, a first push-pull part 333 and a second push-pull part 334 are provided. The push-pull opening 336 between the first push-pull part 333 and the second push-pull part 334 forms a fulcrum that can push the needle winding part 332 out of the needle winding cylinder 331 or push back the needle winding cylinder 331.

[0055] In some embodiments, reference Figure 3 and Figure 4As shown, the winding mechanism 3 also includes a second linkage component 35, a pusher component 36, and a return component 37. The pusher component 36 and the return component 37 are fixed in position and are located on the rotation path of the two winding components 33, respectively. The position of the return component 37 corresponds to the second station, and the position of the pusher component 36 corresponds to the first station. The pusher component 36 pushes the winding part 332 out of the winding cylinder 331 at the first station, so that the dielectric material at the first station can be wound around the winding part 332. Then the winding component 33 rotates with the switching cylinder 31 to the second station. The return component 37 pushes the winding part 332 back into the winding cylinder 331 at the second station, so that the capacitor element after the adhesive is applied at the second station loses the support of the winding part 332 and is picked up and collected by the recovery robot 5.

[0056] The second linkage component 35 is connected to the switching cylinder 31, and to the push needle component 36 and the return needle component 37. The second linkage component 35 can drive the push needle component 36 and the return needle component 37 to move, so as to realize the push or pull drive of the push needle component 36 and the return needle component 37. The second linkage component 35 does not have an additional drive source. Instead, the rotation of the switching cylinder 31 drives the rotation of the second linkage component 35, which is indirectly equivalent to driving the switching cylinder 31 to rotate through the first linkage component 34, and driving the push needle component 36 and the return needle component 37 to move by driving the second linkage component 35.

[0057] Specifically, by connecting the second linkage component 35 to the switching cylinder 31, when the first linkage component 34 drives the switching cylinder 31 to rotate, it synchronously drives the second linkage component 35, so that the second linkage component 35 drives the needle push component 36 to push the needle coiling part 332 out of the needle coiling cylinder 331 at the first station, and the needle return component 37 pulls the needle coiling part 332 back into the needle coiling cylinder 331 at the second station, so as to achieve the driving effect of the needle coiling component 33.

[0058] Further reference Figure 4As shown, the second linkage assembly 35 includes a linkage gear ring 351, a first linkage gear 352, a divider 353, a second linkage gear 354, a third linkage gear 355, a linkage belt 356, a bearing seat 357, a linkage shaft 358, an eccentric wheel 359, a hinge shaft 3511, and a push frame 3512. The linkage gear ring 351 is fixed to the outer wall of the switching cylinder 31, allowing the linkage gear ring 351 to rotate with the switching cylinder 31. The divider 353 is mounted on the frame 1, and the first linkage gear 352 is mounted on the divider 353. Engaging with the linkage gear ring 351, the second linkage gear 354 is connected to the other end of the divider 353. When the linkage gear ring 351 rotates with the switching cylinder 31, it drives the first linkage gear 352 to rotate, and drives the second linkage gear 354 to rotate through the divider 353. The divider 353 is an existing intermittent transmission element, mainly used to convert continuous rotational motion into intermittent rotation. Therefore, under the rotational action of the first linkage gear 352, it is converted into intermittent rotation to the second linkage gear 354.

[0059] Two sets of bearing housings 357 are provided, and a linkage shaft 358 is pivotally connected between the two sets of bearing housings 357. A third linkage gear 355 is installed on the linkage shaft 358, and a linkage belt 356 is sleeved between the second linkage gear 354 and the third linkage gear 355. The linkage belt 356 can be a synchronous toothed belt. Therefore, the linkage belt 356 meshes with the second linkage gear 354 and the third linkage gear 355. When the second linkage gear 354 rotates, it drives the third linkage gear 355 to rotate through the linkage belt 356, thereby causing the linkage shaft 358 to rotate along the bearing housing 357.

[0060] There are two sets of eccentric wheels 359, which respectively drive the push needle assembly 36 and the return needle assembly 37. The two sets of eccentric wheels 359 are installed on the linkage shaft 358 at a preset distance, and the setting position of the eccentric wheels 359 is different depending on the different components connected.

[0061] The hinge frame 3510 is connected to the eccentric wheel 359. The other end of the hinge frame 3510 is hinged to the hinge shaft 3511. When the eccentric wheel 359 rotates, the hinge frame 3510 will not rotate with the eccentric wheel 359 due to the movement of the hinge shaft 3511, but will move with the eccentric wheel 359 and push the hinge shaft 3511 to move. The push frame 3512 is connected to the hinge shaft 3511, thus playing an intermediate pushing role. The push needle assembly 36 and the return needle assembly 37 are respectively connected to a set of push frames 3512, and the connection method is hinged. Therefore, the push frame 3512 can synchronously push the push needle assembly 36 or the return needle assembly 37 to perform push needle or return needle actions.

[0062] Specifically, the linkage gear ring 351 follows the rotation of the switching cylinder 31 to synchronously drive the first linkage gear 352, the divider 353, the second linkage gear 354, the linkage belt 356, and the third linkage gear 355 to rotate, thereby realizing the rotation of the linkage shaft 358 along the bearing seat 357. Two sets of eccentric wheels 359 are set on the linkage shaft 358 to rotate. Through the hinge frame 3510, the hinge shaft 3511, and the push frame 3512, the push frame 3512 drives the push needle assembly 36 to perform the push needle action or the return needle assembly 37 to perform the return needle action. No additional drive components are required, which improves the overall linkage.

[0063] Furthermore, the push needle assembly 36 and the return needle assembly 37 have the same structure, the difference being that the push needle assembly 36 and the return needle assembly 37 are in different positions, and the drive points corresponding to the second linkage assembly 35 are different, that is, the positions of the corresponding eccentric wheels 359 are different. For example, the hinge frame 3510 corresponding to the eccentric wheel 359 of the push needle assembly 36 is located on the rear side, while the hinge frame 3510 corresponding to the eccentric wheel 359 of the return needle assembly 37 is located on the front side. The linkage shaft 358 drives the two sets of eccentric wheels 359 to rotate synchronously. Therefore, the hinge frame 3510 located on the rear side pulls the hinge shaft 3511 and the push frame 3512 on the front side to pull the push needle assembly 36 to move, so that the push needle assembly 36 pushes the needle winding part 332 out of the needle winding cylinder 331. When the push needle assembly 36 is pushed by the push frame 3512, it pushes the needle winding part 332 located at the first station out of the needle winding cylinder 331.

[0064] Conversely, the hinge frame 3510 corresponding to the return needle assembly 37 pulls the hinge shaft 3511 and the push frame 3512 backward to pull the return needle assembly 37 to move. When the return needle assembly 37 is pushed by the push frame 3512, it pushes the needle winding part 332 located in the second station back to the needle winding cylinder 331.

[0065] Specifically, by using different driving points corresponding to the second linkage component 35, the push needle component 36 and the return needle component 37 have the same structure but different directions of action. The push needle component 36 pushes the coiling needle part 332 out of the coiling needle cylinder 331, and the return needle component 37 pushes the coiling needle part 332 back into the coiling needle cylinder 331, so as to realize the winding and separation of the medium material.

[0066] Further, refer to Figure 5As shown, since the pusher assembly 36 and the return assembly 37 have the same structure, this embodiment takes the pusher assembly 36 as an example. The pusher assembly 36 includes a pusher frame 361, a fixed rail 362, a sliding block 363, and a pusher part 364. The pusher frame 361 is pivotally connected to the pusher frame 3512. The fixed rail 362 is installed on the top of the divider 353. The sliding block 363 is slidably connected to the fixed rail 362. The pusher part 364 is installed on the sliding block 363. When the linkage shaft 358 drives the eccentric wheel 359 to rotate, the pusher frame 361 is driven to move through the corresponding hinge frame 3510, hinge shaft 3511, and pusher frame 3512. The pusher frame 361 drives the sliding block 363 and the pusher part 364 to move along the fixed rail 362, so that the movement path of the sliding block 363 and the pusher part 364 is accurate. The pusher part 364 can adopt a cylindrical structure.

[0067] Specifically, when the needle winding assembly 33 follows the first station, the push-pull port 336 between the first push-pull part 333 and the second push-pull part 334 is inserted into the push-needle part 364. The divider 353 is used to make the push frame 3512 intermittently push the push-needle frame 361, so that the push-needle frame 361 drives the sliding block 363 and the push-needle part 364 to move along the fixed rail 362, thereby causing the push-needle part 364 to push the first push-pull part 333 and the needle winding part 332 out of the needle winding cylinder 331.

[0068] The needle return assembly 37 is the same. When the needle pusher 364 corresponding to the needle return assembly 37 is located at the push-pull opening 336 of the needle winding assembly 33 in the second station, the divider 353 is used to make the pusher frame 3512 intermittently push the needle pusher frame 361, so that the needle pusher frame 361 drives the sliding block 363 and the needle pusher 364 to move along the fixed rail 362, thereby causing the needle pusher 364 to push the second push-pull part 334 and the needle winding part 332 to retract the needle winding cylinder 331.

[0069] When the needle winding assembly 33 continues to rotate with the switching cylinder 31, the needle pusher 364 is reset to the position of the push-pull port 336 corresponding to the first or second station according to the rotation of the eccentric wheel 359, thereby providing the needle push or needle return action repeatedly.

[0070] In some embodiments, reference Figure 6 As shown, the drive shaft 341 extends through the switching cylinder 31 to the end away from the drive member 32, and the end is also provided with an abutment cover 343. When the winding needle part 332 extends out of the winding needle cylinder 331, the winding needle part 332 abuts against the abutment cover 343. The function of the abutment cover 343 is to restrict the winding position of the dielectric material during winding, prevent the dielectric material from detaching from the winding needle part 332 during winding, block the detachment path of the dielectric material, and play a role in preventing detachment. At the same time, the abutment cover 343 rotates with the drive shaft 341 to ensure that the capacitor element will not fall out of the winding needle part 332 after winding is completed.

[0071] A CCD detection camera is installed in front of the abutment cover 343 to detect whether the rotation of the switching cylinder 31 is accurate and whether the winding size is accurate during the winding process.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
