Description

Technical Field

[0001] This invention designs a shaping mechanism, specifically relating to a capacitor positive and negative electrode shaping mechanism and shaping method. Background Technology

[0002] Multilayer capacitors are a technologically advanced and high-performance capacitor product. Their high-frequency, low-impedance characteristics are unmatched by ordinary capacitors, making them widely used in electronic products such as tablets, smartphones, and flat-panel displays. During the capacitor manufacturing process, the precision and efficiency of shaping the positive and negative terminals affect the production efficiency and quality of the product.

[0003] In the production of capacitors (especially cylindrical aluminum electrolytic capacitors), the positive and negative leads (or pins) need to be bent and shaped to meet the size and shape requirements of subsequent insertion or installation. Traditional manual shaping methods are inefficient and inconsistent. Existing automated shaping equipment typically has a fixed shaping trajectory or is programmed through a complex servo control system. The former lacks flexibility, requiring the replacement of numerous mechanical parts and cumbersome adjustments when changing product specifications; the latter is costly, with a complex control system and difficult maintenance. Therefore, a mechanism is needed that is relatively simple in structure, low in cost, and possesses good flexibility, capable of quickly adapting to the shaping needs of different capacitor specifications. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a capacitor positive and negative electrode shaping mechanism and method. The capacitor positive and negative electrode shaping mechanism of this invention has a simple structure, is easy to adjust, and can adapt to the shaping of capacitors of different specifications by replacing a few parts, thus overcoming the shortcomings of poor equipment flexibility or high cost in existing technologies.

[0005] To achieve the above technical objectives, the technical solution adopted in the embodiments of the present invention is as follows: In a first aspect, embodiments of the present invention provide a capacitor positive and negative electrode shaping mechanism, including a frame module, an opening and closing shaping module, a capacitor conveying and positioning module, and a driving module; The frame module includes a large base plate and a guide rail bracket mounted thereon; The opening and closing shaping module is slidably mounted on the guide rail bracket and is used to clamp and shape the capacitor electrodes; The capacitor delivery and positioning module is slidably mounted on the guide rail bracket and is used to deliver and position the capacitor. The driving module is used to drive the opening and closing shaping module and the capacitor delivery and positioning module to move; The shaping motion trajectory of the opening and closing shaping module is constrained by a replaceable template, which is independently installed on the frame module.

[0006] Furthermore, the opening and closing shaping module includes: The mounting base plate is connected to the guide rail bracket via the first linear guide rail; A mounting plate is disposed on the mounting base plate; The main arm and the auxiliary arm are detachably mounted on the mounting plate, and the upper ends of the main arm and the auxiliary arm are respectively provided with first rolling bearings for contacting the capacitor electrodes; A trajectory follower is disposed on the main arm and / or the auxiliary arm and contacts the working contour of the template. The drive module drives the mounting base plate to reciprocate along the first linear guide rail, forcing the trajectory follower to move along the contour of the template, thereby controlling the opening and closing of the main arm and the auxiliary arm.

[0007] Furthermore, the trajectory follower is a second rolling bearing disposed at the lower end of the main arm, the template is mounted on the template frame, and the template frame is fixed to the large base plate.

[0008] Furthermore, the drive module includes a first drive unit, which is connected to the mounting plate or mounting base plate via a second joint bearing, for driving the opening and closing shaping module as a whole to move up and down along the first linear guide rail.

[0009] Furthermore, the capacitor delivery and positioning module includes a second linear guide rail, a bracket, a forming mold, and an adjustable stop block assembly; The second linear guide is mounted on the guide bracket; The bracket is slidably mounted on the second linear guide rail; The molding die is detachably mounted on the bracket to support the capacitor; The adjustable stop block assembly is used to limit the movement of the molding die or capacitor to the shaping station, and includes a stop block and a stop block bracket. The stop block is disposed on the stop block bracket, and the stop block bracket is mounted on the guide rail bracket.

[0010] Furthermore, the drive module includes a second drive unit and a motion conversion mechanism. The second drive unit drives the motion conversion mechanism through a first joint bearing. The motion conversion mechanism converts rotational motion into linear motion to drive the bracket to reciprocate along the second linear guide rail.

[0011] Furthermore, the motion conversion mechanism includes a sliding arm and a pusher; The sliding arm is rotatably mounted on the guide rail bracket and connected to the first joint bearing; The pusher is located at the free end of the sliding arm and is used to push or pull the bracket when the sliding arm rotates.

[0012] Furthermore, the pushing component is a third rolling bearing.

[0013] Furthermore, the outline shape of the template is designed and changed according to the specifications of the capacitor and the required shaping size, so as to control the opening and closing amplitude and opening and closing time of the opening and closing shaping module.

[0014] Secondly, embodiments of the present invention provide a method for shaping the positive and negative terminals of a capacitor, employing the capacitor positive and negative terminal shaping mechanism described in the first aspect, comprising the following steps: Step S1: Place the capacitor on the molding die of the capacitor delivery and positioning module; Step S2: The driving module drives the capacitor conveying and positioning module to horizontally convey the capacitor to the shaping station below the opening and closing shaping module and perform positioning. Step S3: The driving module drives the opening and closing shaping module to move downward. During this process, constrained by the contour of the template, the main arm and the auxiliary arm close along a predetermined trajectory. The first rolling bearing at the upper end of the main arm and the auxiliary arm shapes the capacitor electrode according to a predetermined trajectory. Step S4: After the shaping is completed, the driving module drives the opening and closing shaping module to reset upward, and the capacitor delivery and positioning module moves the shaped capacitor horizontally out of the shaping station.

[0015] The beneficial effects of the technical solution provided by the embodiments of the present invention are as follows: (1) High flexibility and easy adjustment: The core of this invention is to control the forming trajectory through a physically replaceable template. When it is necessary to process capacitors of different specifications or different shapes and sizes, only the corresponding template and matching forming mold need to be replaced to change the opening and closing amplitude, timing and motion curve of the main arm and the auxiliary arm. There is no need to adjust the complex program or replace the entire set of actuators. The adjustment is very simple and quick, which greatly improves the versatility and changeover efficiency of the equipment.

[0016] (2) Simple structure and low cost: It uses a purely mechanical template-track follower to replace the expensive multi-axis servo system to realize complex motion trajectories. The overall mechanism is mainly composed of standard parts such as linear guides, bearings, and swing arms, as well as simple machined parts. The structure is reliable and the manufacturing and maintenance costs are low.

[0017] (3) Motion decoupling and high precision: The horizontal entry and exit of the capacitor and the vertical opening and closing of the electrode are completed by two independent drive and guide systems (guided by the first and second linear guides respectively). The actions do not interfere with each other and the trajectory is clear. The linear guides ensure the positional accuracy of the motion. The contact mode between the rolling bearing and the template has low friction, smooth motion, and high repeatability, ensuring the consistency of the shaped products.

[0018] (4) Modular design: The molding mold, template, stop block, etc. are all modular components with standard interfaces, which are convenient for quick disassembly and storage, and are conducive to production management and maintenance. Attached Figure Description

[0027] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "inner" and "outer", "upper" and "lower", "left" and "right" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Example

[0029] A capacitor positive and negative electrode shaping mechanism includes a frame module, an opening and closing shaping module, a capacitor conveying and positioning module, and a drive module.

[0030] The frame module provides a supporting foundation for the entire mechanism, including a large base plate 101 and a guide rail bracket 102 fixedly mounted on it. The guide rail bracket 102 serves as the main mounting frame for other moving parts.

[0031] The opening and closing shaping module is slidably mounted on the guide rail bracket 102 and is used to clamp and shape the capacitor electrode 104. The shaping motion trajectory of the opening and closing shaping module is constrained by a replaceable template 201, which is independently mounted on the frame module.

[0032] The opening and closing shaping module is the core of the shaping function, including the mounting base plate 301, mounting plate 303, main boom 304, auxiliary boom 305, and trajectory follower.

[0033] The mounting base plate 301 is slidably connected to the guide rail bracket 102 via the first linear guide rail 302, ensuring that the entire module can move up and down with high precision in the vertical direction. The mounting plate 303 is fixed on the mounting base plate 301.

[0034] The main arm 304 and the auxiliary arm 305 can be installed on the mounting plate 303 in a relatively openable manner. Each of them has a first rolling bearing 306 fixed by a pin at its upper end. The first rolling bearing 306 directly contacts and squeezes the positive and negative electrodes of the capacitor to shape them.

[0035] In one implementation, the main boom 304 and the auxiliary boom 305 are hinged to the mounting plate 303. The main boom 304 and the auxiliary boom 305 are engaged by their own gear structures, which are respectively located at the hinge points between the main boom 304 and the auxiliary boom 305 and the mounting plate 303. The engagement of the gear structures ensures the stability of the opening and closing of the main boom 304 and the auxiliary boom 305.

[0036] The trajectory follower is mounted on the main arm 304 and contacts the working contour of the template 201; the trajectory follower is a second rolling bearing 307 located at the lower end of the main arm 304, and the gear structure is located between the first rolling bearing 306 and the second rolling bearing 307.

[0037] An independently mounted template 201 is fixed to the base plate 101 via a template holder 202, and its working contour is located on the movement path of the second rolling bearing 307. The contour shape of the template 201 is specially designed according to the pin shaping requirements of the target capacitor (such as bending angle, curvature, spacing, etc.).

[0038] The capacitor delivery and positioning module is slidably mounted on the guide rail bracket 102 and is used to deliver and position the capacitor 103. The capacitor delivery and positioning module includes a second linear guide rail 401, a bracket 402, a forming mold 403, and an adjustable stop block assembly.

[0039] The second linear guide rail 401 is mounted on the guide rail bracket 102, the bracket 402 is slidably mounted on the second linear guide rail 401, and the forming mold 403 is detachably mounted on the bracket 402 to support the capacitor 103. The cavity of the forming mold 403 matches the shape of the capacitor.

[0040] The adjustable stop assembly is used to limit the movement of the molding die 403 or capacitor 103 to the shaping station, ensuring that the capacitor 103 stops at the same position in the shaping station each time.

[0041] The adjustable stop assembly includes a stop 5 and a stop bracket 6. The stop 5 is mounted on the stop bracket 6, and the stop bracket 6 is mounted on the guide rail bracket 102.

[0042] The drive module is used to drive the opening and closing shaping module and the capacitor conveying and positioning module. The drive module drives the mounting base plate 301 to reciprocate along the first linear guide rail 302, forcing the trajectory follower to move along the contour of the template 201, thereby controlling the opening and closing of the main arm 304 and the auxiliary arm 305.

[0043] The drive module includes a first drive unit, which is connected to the mounting plate 303 or the mounting base plate 301 via a second joint bearing 308, and is used to drive the opening and closing shaping module as a whole to move up and down along the first linear guide rail 302.

[0044] When the first drive unit operates, it drives the entire opening and closing shaping module to move downwards along the first linear guide rail 302. During the downward movement, the second rolling bearing 307 is forced to roll along the fixed contour of the template 201, thereby converting the planar curve trajectory of the template 201 into a driving force that controls the opening and closing of the main arm 304 and the auxiliary arm 305 around their hinge points. The first rolling bearing 306 at the upper end of the main arm 304 and the auxiliary arm 305 then extrudes and shapes the capacitor electrodes according to a preset trajectory. After shaping, the first drive unit drives the opening and closing shaping module to rise and reset, and the second rolling bearing 307 moves in the opposite direction along the contour of the template 201, causing the main arm 304 and the auxiliary arm 305 to open.

[0045] The drive module also includes a second drive unit and a motion conversion mechanism. The second drive unit drives the motion conversion mechanism through the first joint bearing 404. The motion conversion mechanism converts the rotational motion into linear motion to drive the bracket 402 to reciprocate along the second linear guide rail 401.

[0046] The motion conversion mechanism includes a sliding arm 405 and a third rolling bearing 406. The sliding arm 405 is rotatably mounted on the guide rail bracket 102 and connected to the first joint bearing 404; The third rolling bearing 406 is disposed at the free end of the sliding arm 405 and is used to push or pull the bracket 402 when the sliding arm 405 rotates.

[0047] When the second drive unit drives the sliding arm 405 to swing back and forth through the first joint bearing 404, the third rolling bearing 406 at the end of the sliding arm 405 will push or pull the bracket 402, so that it makes precise linear reciprocating motion along the second linear guide rail 401, thereby realizing the input and output of the capacitor. Example

[0048] A method for shaping the positive and negative terminals of a capacitor includes the following steps: Step S1, Loading: Place the capacitor 103 to be shaped into the forming mold 403 located in the initial position; Step S2, Feeding and Positioning: The second drive unit operates, driving the sliding arm 405 to rotate through the first joint bearing 404, and the third rolling bearing 406 pushes the bracket 402 forward along the second linear guide rail 401, sending the capacitor 103 to the shaping station until it is stopped by the stop block 5. Step S3, Shaping: The first drive unit moves and pushes the opening and closing shaping module down as a whole through the second joint bearing 308. During the descent, the second rolling bearing 307 is constrained by the contour of the template 201, so that the main arm 304 and the auxiliary arm 305 close along a predetermined trajectory. The first rolling bearing 306 at the upper end of the main arm 304 and the auxiliary arm 305 extrudes and shapes the capacitor electrode 104. Step S4, Reset and Delivery: After the shaping is completed, the first drive unit drives the opening and closing shaping module to move upward and reset, the main arm 304 and the auxiliary arm 305 open, and then the second drive unit drives the sliding rotating arm 405 to rotate in the opposite direction, and pulls the bracket 402 back to the initial position through the third rolling bearing 406, and takes out the shaped capacitor 103, completing one working cycle.

[0049] When processing capacitors of different specifications, operators only need to replace the forming mold 403 that matches the capacitor, and replace or adjust the template 201 that corresponds to the forming curve, and fine-tune the position of the stop block 5, thereby controlling the opening and closing amplitude and opening and closing time of the forming module, so as to quickly complete the equipment changeover and greatly improve production flexibility.

[0050] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
