[0014] Further, the cutting assembly further includes a two-axis moving platform, the fixed knife seat is installed on the two-axis moving platform, and the two-axis moving platform realizes vertical lifting motion and horizontal advancing and retreating motion, so that the cutting assembly moves to the top end position of the pin after spiral forming.

[0015] Further, the electromagnetic brake is further included, the electromagnetic brake is arranged on the half shaft, and is used for applying a braking torque to the half shaft to forcibly adjust the differential ratio of the differential assembly.

[0016] Further, the pin root fixer includes two clamping blocks for clamping the root areas of the two pins from both sides, so that the super capacitor body is prevented from rotating during pin forming.

[0017] The application discloses a shaping and pin cutting method for supercapacitor processing, and comprises the following steps: fixing a supercapacitor to be processed on a clamping platform, with two pins extending vertically upward; clamping the top ends of the two pins by a twisting chuck respectively; starting a main twisting motor, distributing power to two output ends through a differential assembly, and automatically adjusting the rotation speed ratio of the two output ends according to the winding resistance difference of the two pins; the power of the two output ends is transmitted to two sleeve shafts through transmission mechanisms respectively, the sleeve shafts are driven to rotate around guide columns, the twisting chucks on the eccentric rotating arms are driven to move in a circle, and the two pins are wound around the peripheries of the corresponding guide columns to form spiral structures; during the spiral forming process, the vertical feeding motion of the guide column assembly is controlled through an independent feeding drive unit, and a spiral with a set pitch is formed; after the spiral forming is completed, the top end portions of the two pins are simultaneously cut off through a synchronous pin cutting unit, and clamping marks are removed.

[0018] The application has the following beneficial effects:

[0019] Firstly, the device realizes integrated processing of shaping and pin cutting, and fundamentally eliminates secondary clamping errors. Since the double-channel twisting forming unit and the synchronous pin cutting unit are integrated on the same device, the supercapacitor can be subjected to pin cutting operation without being transferred after spiral forming. The workpiece always remains in a fixed position on the supercapacitor body clamping platform, and the spiral forming and pin cutting two processes are completed in the same coordinate system, so that the accuracy of the pin cutting position is completely determined by the mechanical accuracy of the device itself and is not affected by the transfer and repositioning of the workpiece. The integrated design ensures the high consistency of the pin cutting position.

[0020] Secondly, the application of the differential power distribution unit ingeniously solves the forming problem caused by the material characteristic difference of the two pins. According to the mechanical principle, the differential assembly automatically senses the winding resistance difference on both sides, and can realize adaptive distribution of the rotation speed and torque without complex electronic control. When the winding resistance of the thin pin (such as 0.8mm in diameter) is small, the differential assembly automatically increases the rotation speed of the sleeve shaft on this side through differential motion; when the winding resistance of the thick pin (such as 1.0mm in diameter) is large, the rotation speed of the sleeve shaft on this side is automatically reduced. More importantly, the torque distribution is also adjusted, the thin pin side obtains smaller torque to prevent excessive stretching and fracture, and the thick pin side obtains larger torque to ensure sufficient forming. The pure mechanical adaptive mechanism is more reliable than electronic synchronous control and has lower cost.

[0021] Thirdly, the coaxial nesting structure of sleeve shaft-guide column matches the eccentric rotating arm to realize the precise and controllable spiral forming. The sleeve shaft is sleeved on the periphery of the guide column and rotates around it. The eccentric rotating arm drives the twist chuck to make stable circular motion around the guide column, and the pins are naturally wound on the outer surface of the guide column to form a spiral. The spiral diameter is determined by the guide column diameter and the eccentric distance, and the geometric relationship is clear, and the forming precision is high. At the same time, the guide column can rotate freely, which greatly reduces the sliding friction between the pins and the guide column, reduces the forming resistance, and improves the pin surface quality.

[0022] The design of the independent feeding drive unit ensures the uniformity of the pitch. The feeding motion is driven by an independent servo motor through a ball screw, which is not affected by the load change of the twist system. Even during the process of adjusting the rotational speed on both sides of the differential assembly, the feeding speed can remain constant or change according to the preset program, ensuring the pitch accuracy of the spiral.

[0023] The integrated design of the synchronous pin cutting unit completely solves the problem of clamping marks. Since the pin cutting operation is performed immediately after spiral forming, it can accurately position and cut off the pin tip part containing the clamping marks. Two cutting components act simultaneously to ensure that the lengths of the two pins are consistent. The cut-off length of 5-10mm corresponds to the clamping area of the twist chuck, which not only eliminates surface defects but also maximizes material waste.

[0024] From the perspective of equipment investment, this device replaces the traditional two independent devices with an integrated system, significantly reducing equipment procurement costs. The configuration of the differential assembly plus two motors is more economical than two independent servo drive systems. At the same time, the equipment footprint is reduced by about 40%, and the workpiece does not need to be transferred between devices, resulting in a production efficiency increase of more than 30%.

[0025] In summary, the present embodiment combines the differential assembly self-adaptive distribution, the sleeve shaft-guide column coaxial nesting, the bevel gear steering transmission, the independent feeding control, and the synchronous pin cutting, etc. innovative mechanisms, not only solves the problems of the prior art, but also realizes the overall improvement of processing precision, production efficiency and economy.

DETAILED DESCRIPTION

[0031] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that discussions of these implementations are merely provided to enable those skilled in the art to better understand so as to better implement the subject matter described herein, and are not intended to limit the scope of the disclosure. Various procedures or components described in some examples can be omitted, replaced, or added as needed in other examples. Additionally, features described in some examples can be combined in other examples.

[0032] In at least one embodiment of the present disclosure, a shaping and cutting foot device for super capacitor processing is disclosed, as shown in the figure, comprising: a base frame 100, a super capacitor body clamping platform 600, a differential power distribution unit, a double-channel torsion shaping unit, an independent feeding driving unit and a synchronous cutting foot unit. Figure 1 Figure 4 As shown, it includes a base frame 100, a super capacitor body clamping platform 600, a differential power distribution unit, a double-channel torsion shaping unit, an independent feeding driving unit and a synchronous cutting foot unit.

[0033] The base frame 100 provides support for the entire device, the super capacitor body clamping platform 600 is fixed at the lower part of the base frame 100, used for clamping and positioning the super capacitor body to be processed. The differential power distribution unit is installed in the middle of the base frame 100, including a main torsion motor 200 and a differential assembly 201, the output shaft of the main torsion motor 200 is connected to the planetary carrier of the differential assembly 201, and the left and right two half shafts of the differential assembly 201 are horizontally coaxial output, which can automatically adjust the speed ratio of the two sides output according to the load resistance.

[0034] ​The double-channel twist forming unit includes two sets of symmetrical spiral forming mechanisms. Each set of spiral forming mechanism includes a vertical guide column 300, a sleeve shaft 301 sleeved on the outer periphery of the guide column 300, an eccentric rotating arm 302 fixed on the upper end of the sleeve shaft 301, and a twist chuck 303 installed at the end of the eccentric rotating arm 302. The sleeve shaft 301 is a hollow cylindrical structure, and its inner diameter is slightly larger than the outer diameter of the guide column 300. The sleeve shaft 301 is rotatably connected to the guide column 300 through a rolling bearing, so that the sleeve shaft 301 can rotate around the central axis of the guide column 300. The eccentric rotating arm 302 extends radially from the upper end of the sleeve shaft 301, and the end thereof has a set eccentricity relative to the central axis of the guide column 300. The twist chuck 303 is used to clamp the top end of the pin.

[0035] The differential power distribution unit is connected to the double-channel twist forming unit through a power steering transmission mechanism. Since the two half shafts of the differential assembly 201 are arranged horizontally and coaxially, and the two sleeve shafts 301 are arranged vertically and in parallel, a 90-degree power steering is required. The end of the left half shaft is fixed with a driving bevel gear 304, which is engaged with a driven bevel gear 305 arranged vertically. The driven bevel gear 305 is fixed on the lower end of the left intermediate transmission shaft 306. The left intermediate transmission shaft 306 is arranged vertically and supported on the base frame 100 through a deep groove ball bearing. The upper end of the left intermediate transmission shaft 306 is connected to the lower end of the left sleeve shaft 301 through a flexible coupling. The right side adopts the same structure of bevel gear pair and intermediate transmission shaft 306 to realize the power transmission from the right half shaft to the right sleeve shaft 301.

[0036] The bevel gear pair is a straight bevel gear or a spiral bevel gear, with a transmission ratio of 1:1, a module of 2, and a tooth number of 20. The driving bevel gear 304 is fixed on the end of the half shaft through a key connection, and the driven bevel gear 305 is fixed on the lower end of the intermediate transmission shaft 306 through a key connection. The engagement of the bevel gear pair is adjusted by adjusting shims to adjust the side clearance and ensure smooth transmission.

[0037] The guide column 300 is a replaceable structure, and the diameter specifications include 10mm, 12mm, 15mm, 18mm and 20mm, which can be selected according to the required spiral diameter. The upper end of the guide column 300 is supported on the upper cross beam of the base frame 100 through a deep groove ball bearing, and the lower end is supported on the middle cross beam of the base frame 100 through a thrust bearing, so that the guide column 300 can rotate freely and reduce the friction resistance when the pin is wound.

[0038] The eccentric rotating arm 302 is an adjustable structure, including a fixed part and a sliding part. The fixed part is fixed on the upper end of the sleeve shaft 301 by bolts, and the sliding part can slide along the radial guide rail of the fixed part and be fixed at the required position by locking screws, realizing stepless adjustment of the eccentricity in the range of 5mm to 15mm.

[0039] In order to prevent the super capacitor body from rotating during the pin shaping process, a pin root fixer is arranged on the super capacitor body clamping platform 600. The pin root fixer includes two V-shaped clamping blocks that clamp the root regions of the two pins from both sides, and the V-shaped clamping blocks are driven to clamp and loosen by the driving cylinder 503.

[0040] In order to realize active differential ratio adjustment, electromagnetic brakes are installed on the left and right half shafts. The electromagnetic brake includes a stator fixed on the base frame 100 and a rotor fixed on the half shaft, and the braking torque is adjusted by controlling the current of the stator coil. When it is necessary to forcibly change the differential ratio, partial braking force is applied to one side half shaft to force the differential assembly 201 to distribute more power to the other side.

[0041] In order to monitor the winding resistance during the shaping process, a torque sensor is installed on the intermediate transmission shaft 306. The torque sensor adopts a strain gauge structure to detect the torque borne by the intermediate transmission shaft 306 in real time, and when the torque of a certain side approaches the yield limit of the pin material, the rotational speed of that side is reduced or the machining is paused through the electromagnetic brake.

[0042] The independent feeding drive unit includes a feeding servo motor 402, a ball screw transmission mechanism 400, and a moving platform 403. The ball screw transmission mechanism 400 includes two ball screws 401 and two screw nuts, and the screw nuts are installed on the ball screws 401; the feeding servo motor 402 is independent of the torsion drive system, and its output shaft is connected to the ball screws 401 through a shaft coupling. The ball screws 401 are arranged in the vertical direction, and the screw nuts are fixed on the moving platform 403. The moving platform 403 carries the guide column 300 support structure of the left and right spiral shaping mechanisms.

[0043] The lead of the ball screw 401 is 5 mm, and the precise control of the servo motor 402 achieves a repeat positioning accuracy of ±0.01 mm. The feeding speed is adjusted in real time by the servo motor 402, and the required feeding speed is automatically calculated according to the set pitch parameter and the current torsion speed to realize constant pitch or variable pitch spiral shaping.

[0044] The synchronous pin cutting unit is arranged above the position of the spiral and includes two independent cutting assemblies 500. Each cutting assembly 500 includes a fixed knife holder 501, a movable cutting knife 502, and a driving cylinder 503. The fixed knife holder 501 is installed on the two-axis moving platform 403, the movable cutting knife 502 is connected to the fixed knife holder 501 through a hinge, and the piston rod of the driving cylinder 503 is connected to the driving arm of the movable cutting knife 502. The two-axis moving platform 403 can realize vertical lifting and horizontal advancing and retreating movements, so that the cutting assembly 500 can move to the position of the top end of the shaped pin.

[0045] The cutting edges of the fixed seat 501 and the movable cutter 502 are made of hard alloy material, and the cutting edge angle is 15 degrees, which can cleanly cut off the pin material with a diameter of 0.5mm to 2mm. The two-axis moving platform 403 of the shearing assembly 500 is driven by a stepping motor, and the precise positioning is realized by cooperating with the photoelectric sensor.

[0046] In order to improve the cutting precision, a visual positioning system is installed on the shearing assembly 500. The visual positioning system includes an industrial camera and an image processing unit, which can identify the position of the pin tip after spiral forming, automatically adjust the position of the shearing assembly 500, and ensure accurate cutting at the set position.

[0047] The steps of the implementation

[0048] The steps of the supercapacitor shaping and pin cutting device of the embodiment are as follows:

[0049] Step 1: Workpiece loading and initial positioning: place the supercapacitor to be processed on the supercapacitor body clamping platform 600, and clamp and fix the supercapacitor body, with the two pins extending vertically upward. Start the pin root fixer, and the V-shaped clamping block clamps the pin root from both sides to prevent the supercapacitor body from rotating during subsequent processing. Adjust the distance between the left and right guide columns 300 according to the pin spacing, so that the center of the guide column 300 is at a distance equal to the preset eccentricity from the corresponding pin.

[0050] Step 2: Clamping preparation and parameter setting: lower the guide column 300 and sleeve shaft 301 assembly to the initial position. Rotate the eccentric rotating arm 302 to the appropriate angle, so that the torsion chuck 303 is aligned with the pin tip. Open the torsion chuck 303 and move it forward to clamp the 5-8mm length of the pin tip. Set the initial working parameters according to the diameter difference of the two pins, including the basic rotation speed, feed speed and screw pitch value.

[0051] Step 3: Differential screw forming process: start the main torsion motor 200, and input power through the planetary carrier of the differential assembly 201. The power is distributed to the left and right half shafts through the differential assembly 201. The rotational motion of the left half shaft is transmitted to the driven bevel gear 305 through the driving bevel gear 304, which realizes a 90-degree turn, and the driven bevel gear 305 drives the left intermediate transmission shaft 306 to rotate. The intermediate transmission shaft 306 transmits power to the left sleeve shaft 301 through a flexible coupling. The sleeve shaft 301 rotates around the center of the guide column 300, driving the eccentric rotating arm 302 fixed thereon to rotate synchronously. The torsion chuck 303 at the end of the eccentric rotating arm 302 makes a circular motion around the guide column 300, with a radius equal to the eccentricity setting value, and the pin is wound around the periphery of the guide column 300 under the action of this circular motion.

[0052] The right side achieves the same result through the same transmission path. The key is that when the winding resistance of the two pins is different, the differential assembly 201 automatically comes into play. For example, the left pin is 0.8mm in diameter, with smaller winding resistance; the right pin is 1.0mm in diameter, with larger winding resistance. The planetary bevel gears in the differential assembly 201 begin to rotate, automatically increasing the left half shaft speed to 75rpm and automatically reducing the right half shaft speed to 45rpm. At the same time, the torque is distributed in proportion to the resistance, with the smaller torque on the thin pin side to avoid breaking, and the larger torque on the thick pin side to ensure sufficient shaping.

[0053] At the same time, the servo motor 402 of the independent feeding drive unit starts to drive the moving platform 403 to feed upward through the ball screw 401. The feeding speed is automatically adjusted according to the set pitch and the current average rotation speed, ensuring the formation of uniform spiral lines. The guide column 300 is passively rotated under the action of the pin winding force, reducing the friction resistance.

[0054] In some embodiments, step 3 also includes a dynamic adjustment process: the torque sensor monitors the torque value of the intermediate transmission shaft 306 in real time, and when it detects that the torque on one side is close to the yield limit of the pin material, the electromagnetic brake on the corresponding side applies partial braking force, forcibly reducing the rotation speed on that side to prevent the pin from breaking.

[0055] Step 4: cutting position adjustment and execution: after the spiral shaping is completed, the twist chuck 303 loosens and retreats. The two-axis moving platform 403 of the synchronous cutting unit drives the cutting assembly 500 to move to the working position. First, vertical lifting motion is performed to raise the cutting assembly 500 to the height of the spiral top; then horizontal advance and retreat motion is performed to move the fixed knife holder 501 and the movable cutting knife 502 to the cutting position on both sides of the pin.

[0056] In some embodiments, step 4 includes a visual positioning process: an industrial camera takes an image of the pin after spiral shaping, an image processing unit identifies the pin tip position and the clamping mark area, automatically calculates the optimal cutting position, and controls the two-axis moving platform 403 to fine-tune, ensuring that the clamping mark is removed while the effective length is maximized.

[0057] Step 5: synchronous cutting and workpiece unloading: the drive cylinders 503 of the left and right cutting assemblies 500 act simultaneously, and the movable cutting knife 502 closes to the fixed knife holder 501, and the two pins are cut off at the same time. The cut part includes the indentation and deformation produced during the clamping process, with a length of about 5-10mm. After cutting, the cutting assembly 500 retreats to the initial position, the pin root holder loosens, and the finished supercapacitor is removed from the clamping platform.

[0058] In some embodiments, step 5 further comprises: before the cutting action, fine-tuning the relative positions of the two cutting assemblies 500 by the servo motor 402 to compensate for the difference in the height of the spiral caused by the difference in the diameters of the pins, so as to ensure that the lengths of the two pins after the cutting action are consistent.

[0059] The above describes the embodiments of the present application, but the embodiments are not limited to the specific implementation described above, which is only illustrative but not restrictive, and those skilled in the art can make more forms of equivalent embodiments under the inspiration of the embodiments, which are all within the protection of the embodiments.
