Description

Technical Field

[0001] This invention relates to the technical field of integrated equipment for stamping and assembling split terminals, specifically to integrated equipment for stamping and assembling split terminals and its processing method. Background Technology

[0002] Battery terminals are the core conductive connection components of various types of batteries, such as lead-acid batteries and energy storage batteries. They mainly undertake the key functions of battery current transmission and external circuit connection. Their processing accuracy, structural strength, conductivity and assembly stability directly determine the battery's performance, service life and operational safety.

[0003] Currently, the mainstream battery terminals are split composite structures that combine sheet-like connection structures and columnar electrode structures, and the materials are mostly copper and lead composite materials. Among them, the molding and processing quality of the terminals is the core prerequisite for determining their basic performance and reducing the probability of later maintenance failures.

[0004] At present, the forming and processing technology of the above-mentioned split battery terminals in the industry is mainly divided into casting forming process, and some companies also use stamping assembly forming. Both of the above processing methods have inherent technical defects, making it difficult to balance processing efficiency, finished product accuracy, structural strength and assembly yield, and failing to meet the industry's current demand for high precision, high stability and mass production of batteries.

[0005] Among them, casting is a traditional terminal processing method, in which a terminal blank is formed by casting molten metal. However, this process has poor forming precision, and the surface of the casting is prone to defects such as burrs and flash. After casting, secondary finishing processes such as grinding and fine finishing must be carried out. The overall processing flow is cumbersome, consumes a lot of manpower and material resources, and has a long production cycle. At the same time, during the molten metal casting process, air is easily trapped inside the melt. After cooling and forming, microscopic defects such as air bubbles and porosity will remain inside the terminal. This not only significantly reduces the overall structural strength of the terminal, causing the terminal to be prone to cracking and deformation during assembly and use, but also damages the integrity of the terminal's conductive structure, resulting in decreased conductivity uniformity and increased resistance. This seriously affects the conductivity and working stability of the battery, resulting in a high product defect rate.

[0006] To overcome the shortcomings of the casting process, the industry has gradually adopted a stamping assembly process for processing split battery terminals. The core idea is to process sheet-like and columnar structures separately, and then assemble and weld them into a finished product. However, the current separate independent stamping and pressing process first uses copper strips to stamp flat sheet-like structures separately using specialized stamping equipment. Then, the formed sheet-like workpieces are transferred to the pressing equipment station, where columnar structures are placed manually or mechanically. The sheet-like and columnar structures are then combined into a three-dimensional integral terminal product through pressing. Although this process avoids the internal air bubble problem of the casting process, the processing steps are highly fragmented, covering multiple independent processes such as raw material stamping, workpiece transfer, positioning, and pressing. The production process is cumbersome, with long intervals between processes, resulting in low overall production efficiency and the inability to achieve automated continuous mass production, which seriously restricts the terminal processing capacity.

[0007] Meanwhile, the aforementioned process involves cutting and separating semi-finished material plates using a cutting device to obtain sheet-like structural workpieces, which are then transferred to the pressing station for pressing and assembly with columnar structures. During the cutting of the semi-finished material plates, the high temperature during cutting can generate residual stress inside the workpiece. Furthermore, the cut sheet-like structural workpieces are highly susceptible to micro-deformation due to external forces and stress release during subsequent transportation, station transfer, and pressing and positioning. This can lead to deviations in the dimensional accuracy of assembly holes and strip assembly positions in the sheet-like structure, as well as exceeding the dimensional tolerances. Ultimately, this results in problems such as positioning deviations, misalignment, and loose bonding between the sheet-like and columnar structures, significantly increasing the terminal assembly defect rate, resulting in poor product consistency. In later use, this can easily lead to faults such as poor contact, loosening, and overheating, seriously affecting the reliability of the battery.

[0008] In summary, existing battery terminal casting and assembly processes both suffer from unavoidable technical defects. They generally exhibit problems such as cumbersome processing steps, long production cycles, high equipment costs, poor finished product precision, insufficient structural strength, low assembly yield, and poor product consistency, making them unsuitable for the high-efficiency, high-precision, and high-yield mass production requirements of modern batteries. Therefore, developing equipment and corresponding processing methods that can achieve integrated continuous processing of split-type terminal stamping and assembly, simplifying production processes, eliminating workpiece deformation defects, reducing assembly defect rates, and improving processing efficiency and finished product quality has become a pressing technical problem for those skilled in the art. Summary of the Invention

[0009] In view of this, the present invention proposes a separate terminal stamping and assembly integrated equipment and its processing method to solve the problems existing in the prior art.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a split-type terminal stamping and assembly integrated equipment, comprising: a first component;

[0011] The first component includes a frame, a stamping assembly table is fixedly connected to the lower part of the frame, a stamping device is provided on the frame, and a cutting blade is fixedly connected to the bottom surface of the stamping device;

[0012] An intermittent feeder is provided on one side of the frame, on which raw material strips are conveyed. A guide groove is fixedly connected to the stamping assembly platform. The end of the raw material strip away from the intermittent feeder is located in the guide groove. A discharge chute is fixedly connected to the side of the stamping assembly platform away from the intermittent feeder.

[0013] A storage box and a vibratory feeder are provided on the side of the frame away from the intermittent feeder;

[0014] The stamping assembly platform is equipped with a conveying device, and the conveying device is equipped with a pushing component. The end of the conveying device is fixedly connected to the material feeding end of the vibratory feeder.

[0015] Preferably, a second component is also included;

[0016] The second component includes a column structure, which is initially placed inside the vibratory feeder, and the outer periphery of the column structure is provided with stepped protrusions;

[0017] The raw material strips are stamped to form an interconnected sheet-like structure.

[0018] As a preferred option, a third component is also included;

[0019] The third component includes an auxiliary plate, the bottom surface of which is fixedly connected to an abutment wheel via a spring body, and an edge pressure strip is fixedly connected to one side of the abutment wheel bracket;

[0020] A transverse groove is provided on the edge pressure strip, and a transverse wiping strip is slidably connected in the transverse groove.

[0021] Preferably, the auxiliary plate is fixedly connected to the upper surface of the guide groove, and the edge pressure strip is located above the edge of the raw material strip and abuts against its edge.

[0022] Preferably, the cutting blade on the stamping equipment is positioned close to the discharge trough, that is, fixedly connected to the rightmost end of the bottom surface of the stamping equipment.

[0023] Preferably, the abutting wheel and the edge pressing strip constitute a raw material edge limiting group.

[0024] The processing method of the split-type terminal stamping and assembly integrated equipment adopts an integrated operation mode of first stamping the raw materials, then pressing them together, and finally cutting them, including the following steps:

[0025] Step 1: Raw material conveying and pretreatment

[0026] The intermittent feeder drives the raw material strip to move intermittently along the guide trough. The third component limits, corrects, and cleans the surface of the raw material strip, ensuring that the raw material is conveyed smoothly and the surface is clean.

[0027] Step 2: Stamping of continuous blanks

[0028] After the raw material strip is conveyed to the stamping station, the feeding is paused and the integrated operation process is carried out. First, the stamping equipment stamps the raw material strip to process the interconnected sheet structure. At this time, the stamped sheet structure is connected to the raw material strip.

[0029] Step 3: Feeding and positioning of column components

[0030] The vibratory feeder transports the column structure, which is then conveyed to the pressing station by the conveying equipment and pusher, so that the column structure and the sheet structure are aligned.

[0031] Step 4: Integrated Press Molding

[0032] The integrated operation process involves pressing down the stamping equipment to fit the sheet structure onto the outside of the column structure. Axial positioning is achieved by using the stepped protrusions on the column structure, thus completing the press-fitting combination of the two.

[0033] Step 5: Post-processing slitting and separation

[0034] After pressing is completed, the final cutting process of the integrated operation is performed. The stamping equipment drives the cutting blade to cut the assembled terminals from the continuous raw material strips to obtain individual finished terminals.

[0035] Step Six: Finished Product Collection

[0036] After being cut, the finished terminals slide down the discharge trough into the storage box for centralized storage. The equipment continuously executes the above integrated process to achieve continuous production.

[0037] Compared with the prior art, the present invention provides a split-type terminal stamping and assembly integrated equipment, which has the following beneficial effects:

[0038] 1. This invention, through its integrated design of "first punching out holes, then assembling, and finally cutting," offers the following advantages:

[0039] Effectively avoids the defects of traditional casting process and improves the structural strength and conductivity of the terminal: This design abandons the traditional casting method of battery terminals and adopts the process mode of cold stamping of raw material strips into sheet blanks. This effectively avoids micro-defects such as melt entrapment, internal porosity, and bubbles in the casting process, ensuring the overall density and structural integrity of the terminal, and improving the overall strength and conductivity uniformity of the terminal.

[0040] Eliminating workpiece deformation during transport and significantly reducing terminal assembly defect rate: This design overcomes the problems of easy workpiece deformation and poor assembly accuracy caused by the existing split stamping process of first forming sheet-like finished products and then independently transporting and pressing them. It adopts an integrated process of "first stamping and drilling holes, then pressing in place, and finally cutting." After the sheet-like structure is stamped, it remains connected to the raw material strip, maintaining an overall rigid positioning state. No separate sorting, conveying, or secondary transfer is required. This effectively avoids problems such as micro-deformation of the blank, hole misalignment, and out-of-tolerance form and position issues caused by residual stress release and external interference during semi-finished product cutting and transport. It effectively ensures the assembly alignment accuracy of the sheet-like structure and the cylindrical structure, eliminating defects such as misalignment and loose fit, and significantly improving the finished product assembly yield and product consistency.

[0041] The highly integrated and simplified process shortens the production cycle and adapts to the needs of automated mass production: This design integrates multiple processes such as stamping, column pressing, and finished product slitting into one seamless unit. This replaces the cumbersome traditional production model of independent stamping, pressing, and multi-process transfer, significantly streamlining production processes, shortening processing cycles, and reducing equipment investment and material handling costs. Simultaneously, the integrated continuous operation mode enables automated continuous production, effectively solving the problems of dispersed processes, low production efficiency, and limited capacity in traditional separate processing techniques. With its simple structure, mature technology, ease of mass production, and strong adaptability, it can meet the modern production needs of large-scale, high-efficiency, and high-yield battery terminals.

[0042] 2. The present invention, through the optimized design of adding a stepped protruding surface to the column structure, can bring the following benefits:

[0043] Achieving precise axial positioning, avoiding assembly offset issues, and improving assembly forming accuracy: This design utilizes the stepped protrusion surface of the column structure as the abutment and positioning reference. After the sheet structure is sleeved on the outer periphery of the column structure, it can directly and precisely abut and position itself against the stepped protrusion surface. This can precisely constrain the axial assembly position of the sheet structure, effectively limiting the movement and offset of the sheet structure during the pressing process, avoiding problems such as over-alignment, under-alignment, and tilting misalignment. This further improves the assembly alignment accuracy and fitting regularity of the sheet structure and the column structure, ensuring the consistency of the assembly dimensions of each batch of terminals.

[0044] Increasing the structural contact area, optimizing the conductive path, and improving the terminal conductivity stability: This design overcomes the drawbacks of traditional simple sleeve connections, partial line contact, or small-area contact between cylindrical and sheet structures. Through the abutment of stepped protruding surfaces, this design significantly increases the effective contact area between the cylindrical and sheet structures, reduces assembly gaps and contact blind spots, constructs a more complete and unobstructed conductive path, effectively reduces terminal contact resistance, and avoids problems such as localized heating, uneven conductivity, and performance degradation under high current conditions caused by insufficient contact area. This significantly improves the overall conductivity and long-term operational stability of the battery terminals.

[0045] Strengthening structural torsional resistance and connection strength, improving the overall structural reliability and service life of the terminals: The stepped protrusions provide reliable support, limiting and locking for the sheet structure, making the sheet structure and the column structure an integrated locking fit structure. This significantly improves the torsional resistance, shear resistance and loosening resistance of both, effectively preventing the sheet structure from loosening, rotating and slipping during assembly and locking, vehicle vibration and working conditions. It also enhances the overall structural rigidity and connection firmness of the terminals, improves the fatigue resistance and service life of the terminals, and ensures the long-term safe and stable operation of the battery.

[0046] 3. This invention, by using a single raw material strip to stamp an interconnected sheet-like structure blank and then performing a subsequent slitting design after pressing, offers the following advantages:

[0047] Avoiding thermal stress and deformation defects during cutting, and stabilizing the hole position accuracy of sheet structure: This design changes the traditional process logic of cutting semi-finished raw materials separately in advance and forming individual sheet blanks first. The cutting process is placed after the pressing and forming is completed. This effectively avoids the residual stress inside the material generated by the high temperature of traditional cutting process. It avoids the micro deformation problem caused by stress release and external force disturbance during the entire process of conveying, transferring, station transfer and pressing and positioning of individual sheet blanks. It effectively ensures the shape, diameter and position accuracy of the holes in the sheet structure, avoids hole distortion and offset and other problems, and greatly improves the basic accuracy of terminal assembly.

[0048] Eliminating errors in the transfer of free-floating workpieces significantly reduces the defect rate of terminal assembly: This design overcomes the drawbacks of existing processes where individual sheet blanks exist independently and are transferred freely throughout the process, making them prone to placement misalignment, stress deformation, and hole deformation, leading to assembly failure. In this design, the sheet structure remains continuously connected to the raw material strip throughout the initial processing stage. Relying on the overall rigidity of the raw material strip, stable positioning is achieved throughout the process. There is no transfer of independent individual workpieces or secondary alignment processes, effectively avoiding assembly defects such as misalignment, hole misalignment, and poor fit caused by blank deformation and hole distortion. This significantly improves the product assembly qualification rate and batch consistency.

[0049] 4. The design of the third component in this invention offers the following advantages:

[0050] This design achieves full-process elastic limiting and correction of raw material strips, avoiding stamping defects and further improving the yield of finished products: Based on the integrated process of "stamping holes first, then assembling, and finally cutting", this design uses abutment wheels and edge pressure strips to form a raw material edge limiting group. Relying on the spring body to elastically press the edge of the raw material strip, it can limit the raw material strip during intermittent conveying, effectively preventing problems such as bending, warping, detachment from the guide groove, and moving away from the equipment bonding surface during the conveying and stamping process of the raw material strip. It ensures that the raw material strip always maintains a flat and fitted processing state, avoiding defects such as stamping deformation, hole position deviation, and forming defects caused by raw material displacement and uneven force. On the basis of avoiding stress deformation in the integrated process, it further reduces the probability of forming defects and significantly improves the terminal press-fit yield.

[0051] Eliminating impurities and avoiding stamping scratches, thus improving terminal forming quality: This design overcomes the drawbacks of dust and oil adhering to the surface of raw materials in the workshop production environment, which can easily affect stamping accuracy and the appearance quality of the finished product. Through a transverse wiping strip installed on the upper surface of the raw material strip, the surface of the raw material strip can be wiped clean in real time before stamping, effectively removing workshop dust, oil, and other impurities adhering to the raw material surface. This prevents impurities from intervening in the stamping process and causing scratches and surface defects in the stamping parts, ensuring the surface flatness and structural integrity of the sheet blank after stamping, and improving the appearance quality and processing accuracy of the finished terminal.

[0065] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0066] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0067] Example

[0068] Please refer to Figures 1 to 8 As shown:

[0069] To address the problems mentioned in the technical solutions, this application provides a split-type terminal stamping and assembly integrated equipment, including: a first component;

[0070] The first component includes a frame 101, with a stamping and assembly table 102 fixedly connected to the lower part of the frame 101. A stamping device 103 is mounted on the frame 101, and a cutting blade 104 is fixedly connected to the bottom surface of the stamping device 103. An intermittent feeder 105 is mounted on one side of the frame 101, conveying a raw material strip 106. A guide groove 107 is fixedly connected to the stamping and assembly table 102, with the end of the raw material strip 106 away from the intermittent feeder 105 located in the guide groove 107. A discharge trough 108 is fixedly connected to the side of the stamping and assembly table 102 away from the intermittent feeder 105. A storage box 1081 and a vibratory feeder 109 are mounted on the side of the frame 101 away from the intermittent feeder 105. A conveying device 110 is mounted on the stamping and assembly table 102, with a pusher 111 mounted on the conveying device 110. The end of the conveying device 110 is fixedly connected to the feeding end of the vibratory feeder 109.

[0071] It also includes a second component; the second component includes a column structure 201, which is initially set inside the vibratory plate 109, and the outer periphery of the column structure 201 is provided with a stepped protrusion surface 202; the raw material strip 106 is stamped to form an interconnected sheet structure 203.

[0072] in:

[0073] The first component process is as follows: The raw material strip 106 located in the pressing area is first stamped into interconnected sheet-like structures 203 blanks. Then, through the cooperation of the stamping assembly table 102 and the stamping equipment 103, the freshly stamped sheet-like structures 203 on the raw material strip 106 are pressed together with the cylindrical structure 201 conveyed by the conveying equipment 110. After pressing, the structure is cut by the cutting blade 104 on the stamping equipment 103, ultimately forming a terminal (a combination of the cylindrical structure 201 and the sheet-like structure 203). This integrated design of "first stamping holes, then assembling, and finally cutting" effectively avoids many defects of existing casting methods for manufacturing terminals: low precision of castings, presence of burrs, and the need for further finishing after casting, which is time-consuming and labor-intensive; in addition, air bubbles are easily generated inside the cast terminal, affecting its strength and conductivity. Meanwhile, this integrated design also differs from the existing method of first stamping the raw material strip 106 into a sheet structure 203 and then pressing it into the column structure 201. This not only reduces the pressing cycle, but also, the integrated design of pressing immediately after punching is different from the existing method of first stamping into a sheet structure 203 and then separately conveying the column structure 201 and the sheet structure 203 for pressing. This avoids deformation problems during the conveying and transfer of the sheet structure 203 workpiece, which would affect the shape of the holes on the sheet structure 203 and affect the final assembly.

[0074] The intermittent feeder 105 is used to intermittently convey the raw material strip 106, and cooperate with the stamping assembly table 102 and the stamping equipment 103 to carry out stamping and pressing transfer work.

[0075] Raw material strip 106 is a conductive metal strip such as copper or lead.

[0076] The guide trough 107 is used to provide guiding assistance for the conveying of the raw material strip 106.

[0077] After pressing and cutting by the cutting blade 104, the terminals are transferred to the storage box 1081 through the discharge trough 108.

[0078] Vibratory feeder 109 is used to transfer column structure 201 to conveying equipment 110.

[0079] The pusher 111 is driven by an air pump and can intermittently push the column structure 201 in the channel of the conveying equipment 110 to the underside of the stamped blank sheet structure 203 for press-fitting.

[0080] After the sheet structure 203 is fitted onto the outer periphery of the column structure 201, one end of the sheet structure 203 will abut against the stepped protrusion 202 on the column structure 201. The stepped protrusion 202 at this time plays a limiting role, effectively increasing the contact area between the column structure 201 and the sheet structure 203, and improving the torsional resistance.

[0081] The entire raw material strip 106 is stamped into interconnected sheet-like structures 203 blanks, and then slit into individual sheet-like structures 203. In the above process, when the blanks are slit by the slitting equipment, the semi-finished raw materials will experience internal stress due to heat during the cutting process. During the transfer and pre-pressing process, deformation is likely to occur, affecting the shape of the holes in the sheet-like structures 203, which will lead to an increase in the assembly defect rate.

[0082] A further embodiment: Please refer to Figure 1 , Figure 6 , Figure 7 , Figure 9 As shown:

[0083] The third component includes an auxiliary plate 301. An abutment wheel 302 is fixedly connected to the bottom surface of the auxiliary plate 301 via a spring. An edge pressure strip 303 is fixedly connected to one side of the bracket of the abutment wheel 302. A transverse groove is provided on the edge pressure strip 303. A transverse wiping strip 304 is slidably connected in the transverse groove. The auxiliary plate 301 is fixedly connected to the upper surface of the guide groove 107. The edge pressure strip 303 is located above the edge of the raw material strip 106 and abuts against its edge.

[0084] in:

[0085] The third component can further improve the yield of press-fitting by adopting an integrated design that first punches holes in the raw materials, then assembles and cuts them.

[0086] The abutment wheel 302 and the edge pressure strip 303 constitute the raw material edge limiting group, which is set on the bottom surface of the auxiliary plate 301 by the spring body. The abutment wheel 302 and the edge pressure strip 303, which are elastically pressed along the edge of the raw material strip 106, will effectively limit the intermittently conveyed raw material strip 106 to prevent it from bending, curling up, or leaving the guide groove 107 and the contact surface of the stamping assembly table 102. The transverse wiping strip 304 set on the upper surface of the raw material strip 106 can wipe off workshop dust and oil stains on the surface of the raw material strip 106.

[0087] The integrated design, which involves punching holes in the raw material before assembly and cutting, effectively reduces material stress deformation. Furthermore, the third component helps prevent the raw material strip 106 from bending, warping, or detaching from the guide groove 107 and the contact surface of the stamping assembly table 102 during the stamping process, thus preventing uneven stress and forming defects. This component effectively complements the integrated design, further mitigating finished product deformation. Simultaneously, the transverse wiping strip 304 removes workshop dust and oil from the raw material strip 106 before stamping, preventing scratches on the stamping area and reducing the risk of shortened service life and corrosion in humid environments.

[0088] A further embodiment:

[0089] The processing method of the split-type terminal stamping and assembly integrated equipment adopts an integrated operation mode of first stamping the raw materials, then pressing them together, and finally cutting them, including the following steps:

[0090] Step 1: Raw material conveying and pretreatment

[0091] Intermittent feeder 105 drives raw material strip 106 to move intermittently along guide trough 107, and relies on third component to limit and correct the raw material strip 106 and clean its surface, ensuring that the raw material is conveyed smoothly and the surface is clean.

[0092] Step 2: Stamping of continuous blanks

[0093] After the raw material strip 106 is conveyed to the stamping station, the feeding is paused and the integrated operation process is used for processing. First, the stamping equipment 103 stamps the raw material strip 106 to process the interconnected sheet structure 203. At this time, the stamped sheet structure 203 is connected to the raw material strip 106.

[0094] Step 3: Feeding and positioning of column components

[0095] The vibratory feeder 109 transports the column structure 201, which is then transported to the pressing station via the conveying equipment 110 and the pusher 111, so that the column structure 201 and the sheet structure 203 are aligned.

[0096] Step 4: Integrated Press Molding

[0097] Integrating the integrated operation process, the stamping equipment 103 presses down, fitting the sheet structure 203 onto the outside of the column structure 201, and using the stepped protrusion 202 on the column structure 201 to achieve axial limiting, thus completing the press-fitting combination of the two.

[0098] Step 5: Post-processing slitting and separation

[0099] After pressing is completed, the final cutting process of integrated operation is performed. The stamping equipment 103 drives the cutting blade 104 to cut the assembled terminals from the continuous raw material strip 106 to obtain independent finished terminals.

[0100] Step Six: Finished Product Collection

[0101] After being cut, the finished terminals slide down through the discharge trough 108 into the storage box 1081 for centralized storage. The equipment continuously executes the above integrated process to achieve continuous production.

[0102] The working principle of all the content in the above embodiments is as follows:

[0103] Raw material conveying and pre-positioning cleaning:

[0104] Intermittent feeder 105 drives the raw material strip 106 to be conveyed intermittently. The raw material strip 106 moves along the guide groove 107 on the stamping assembly table 102. The third component above the guide groove 107 works synchronously: the abutment wheel 302 below the auxiliary plate 301 and the edge pressure strip 303 elastically press the edge of the raw material strip 106 to limit it and prevent the raw material strip 106 from bending or curling up during conveying; at the same time, the transverse wiping strip 304 on the edge pressure strip 303 wipes the surface of the raw material strip 106 in real time to remove dust and oil stains and avoid impurities from affecting subsequent stamping processing.

[0105] Stamped continuous blank:

[0106] After the raw material strip 106 is conveyed to the stamping station, the stamping equipment 103 on the frame 101 descends to stamp the raw material strip 106, making it into interconnected sheet structures 203. During this process, the sheet structures 203 are always connected to the raw material strip 106 as a whole, maintaining a rigid positioning state.

[0107] Column structure 201 is fed into place:

[0108] The vibratory feeder 109 continuously conveys the column structure 201 in the second component. After the column structure 201 enters the conveying device 110, it is intermittently pushed by the pusher 111 on the conveying device 110 to accurately convey the column structure 201 to the position to be pressed under the stamped sheet structure 203.

[0109] In-situ press-fit assembly:

[0110] The stamping equipment 103 operates again, pressing the sheet structure 203 down to fit onto the outside of the column structure 201. The stepped protrusion 202 on the outer periphery of the column structure 201 abuts against the sheet structure 203, achieving precise axial positioning. This ensures assembly position accuracy, increases the contact area between the two, and improves connection strength and conductivity.

[0111] Post-processing for separation of finished products:

[0112] After the entire set of terminals is pressed and assembled, the cutting blade 104 at the far right of the bottom surface of the stamping equipment 103 performs a splitting operation, cutting the continuous sheet structure 203 from the raw material strip 106 to separate a single complete split terminal product.

[0113] Finished product unloading and storage:
