[0018] The application further provides that the terminal sheet feeding guide rail simultaneously conveys two terminal sheets, the terminal sheet material moving mechanism comprises a rack, a mounting seat slidingly arranged on the rack and a material taking table for respectively taking the terminal sheets, the material taking tables are oppositely arranged on the two sides of the mounting seat and connected with the mounting seat, a middle pressing block for avoiding the terminal sheets from shaking is arranged between the two material taking tables, the middle pressing block is connected with the mounting seat, the spacing between the middle pressing block and the material taking table is matched with the thickness of the terminal sheet, an upper pressing block for pressing the terminal sheet is arranged above the material taking table, a driving cylinder for driving the upper pressing block to slide up and down is arranged on the mounting seat, and a second driving mechanism for driving the two material taking tables to approach or separate is arranged on the mounting seat.

[0020] The present invention further comprises: a bottom cover finished product feeding guide rail is provided between the assembly transfer guide rail and the bottom cover assembly unloading station; a bottom cover flipping mechanism for flipping the bottom cover finished product and a bottom cover finished product transfer mechanism for moving the flipped bottom cover finished product to the bottom cover finished product feeding guide rail are provided between the assembly transfer guide rail and the bottom cover finished product feeding guide rail; a bottom cover assembly worktable is provided on the other side of the bottom cover finished product feeding guide rail opposite to the assembly transfer guide rail; both the bottom cover assembly unloading station and the short spring loading station are provided on the bottom cover assembly worktable; a short spring feeding guide rail is provided on the other side of the short spring loading station opposite to the bottom cover finished product feeding guide rail; a short spring lifting mechanism for lifting the short spring into the bottom cover assembly unloading station is provided below the short spring feeding guide rail corresponding to the short spring loading station.

[0021] By adopting the above technical solution, the bottom cover flipping mechanism flips the riveted bottom cover 180 degrees, the bottom cover finished product transfer mechanism moves the bottom cover finished product to the bottom cover finished product feeding guide, the bottom cover finished product feeding guide conveys the bottom cover finished product to the bottom cover assembly unloading station, and the short spring lifting mechanism lifts the short spring into the bottom cover assembly unloading station, facilitating the bottom cover assembly transfer mechanism to move the bottom cover assembly and short spring to the bottom cover assembly loading station simultaneously. The structure is compact and stable, requiring only one loading without separate loading, resulting in high assembly efficiency. While terminal piece riveting requires a top-to-bottom approach, and the short spring is inserted into the bottom cover in the same direction as the terminal piece riveting, inserting it from above into the upward-facing bottom cover might require complex alignment and release mechanisms. Springs are prone to bouncing and loss. Therefore, a bottom cover flipping mechanism and a bottom cover finished product transfer mechanism are used to flip the bottom cover assembly and push the short spring upward from below. During the upward process, the spring is always constrained by the bottom cover "ceiling". Once it is pushed into place, it will not pop out or shift. Moreover, the short spring pushing mechanism and the bottom cover assembly transfer mechanism work synchronously to ensure that the bottom cover assembly and the short spring are unloaded synchronously, stably and accurately. The short spring pushing mechanism solves the industry problem of the difficulty in grasping, aligning and placing small springs. By pushing from the bottom up, the workpiece itself is used to constrain the spring. The assembly process is gentle and precise, which greatly reduces the risk of spring damage, omission or improper installation and ensures the consistency of the final product quality.

[0022] An operating method for an automatic connector assembly machine includes the following steps: S1: A substrate feeding mechanism moves the substrate on the substrate feeding guide rail to the substrate feeding station of the main disc; S2: The main disc rotates, causing the substrate to move to the handle feeding station, and a handle feeding mechanism moves the handle on the handle feeding guide rail to the handle feeding station of the main disc, whereby the handle is inserted into the substrate; S3: The main disc rotates, causing the substrate to move to the semi-finished product feeding station, whereby a small disc completes the assembly of the long spring, bracket, and springboard assembly into a semi-finished product and moves it to the semi-finished product unloading station, where a semi-finished product transfer mechanism moves the semi-finished product from the small disc's semi-finished product unloading station. S4: The semi-finished product is moved to the semi-finished product loading station and loaded into the base body; S5: The main disc rotates and drives the base body to the bottom cover assembly loading station. At this time, the bottom cover and terminal piece are riveted together in the bottom cover assembly area to form the bottom cover assembly. The short spring loading station pushes the short spring to the bottom cover assembly unloading station. The bottom cover assembly transfer mechanism moves the bottom cover assembly and the short spring to the bottom cover assembly loading station and loads them into the base body; S6: The main disc rotates and drives the base body to the assembly station. The assembly mechanism presses and snaps the bottom cover assembly and the base body together to complete the assembly; S7: The main disc rotates and drives the base body to the main body unloading station to complete the unloading.

[0023] By adopting the above technical solution, this automated assembly method achieves efficient and stable balance in the mass production of multi-component precision connectors through a main disc rotation + parallel operation of sub-modules + step-by-step pressing and positioning architecture. The main disc handles the entire process of the substrate's rotation from "feeding → handle assembly → semi-finished product integration → bottom cover assembly pressing → finished product unloading." The small discs independently complete the semi-finished product pre-assembly of "long spring + bracket + springboard assembly," operating synchronously with the main disc but physically isolated to avoid interference from the main disc's vibration. The bottom cover assembly area simultaneously performs "bottom cover + terminal piece riveting" and "short spring lifting," while the main disc... Before the disc rotates to the bottom cover assembly loading station, pre-preparation is completed, shortening the total assembly time of a single product; the process of base body → handle (internal transmission component) → semi-finished product (elastic trigger component) → bottom cover assembly (sealing + conductive terminal) conforms to the precision assembly principle of "prioritizing the fixing of core functional components and encapsulating auxiliary components later", avoiding interference of the later-installed components with the already positioned parts; the long spring and short spring are respectively fed by independent loading mechanisms in coordination with the main disc, avoiding the problem of spring "jumping and jamming" in manual assembly, and improving the assembly yield; the entire process from base body loading to finished product unloading does not require manual contact, which greatly improves the efficiency and stability of assembly.

[0024] The present invention further includes the following steps in step S3: S31: The long spring feeding mechanism feeds the long spring into the material slot of the long spring feeding station; S32: The small disc rotates, causing the material slot to move to the bracket feeding station, and the bracket transfer mechanism feeds the bracket from the bracket feeding guide rail into the material slot of the bracket feeding station; S33: The small disc rotates, causing the material slot to move to the scaffold assembly feeding station, and the first scaffold assembly transfer mechanism clamps the scaffold assembly from the scaffold assembly feeding guide rail and inserts it into the bracket in the material slot; S34: The small disc rotates, causing the material slot to move to the scaffold assembly feeding station. The trough moves to the semi-finished product unloading station, the first moving component drives the first clamping component to move to the semi-finished product unloading station, and the first lifting component controls the first clamping component to move down and move above the semi-finished product unloading station; S35: the top material mechanism pushes the movable top rod upward, so that the semi-finished product composed of the long spring, bracket and springboard assembly is separated from the placement seat, and the first clamping component simultaneously clamps the semi-finished product composed of the long spring, bracket and springboard assembly; S36: the first moving component and the first lifting component drive the first clamping component to move to the semi-finished product loading station and place it into the semi-finished product loading station.

[0025] By adopting the above technical solutions, the assembly of semi-finished products and the assembly of finished products on the main disc are carried out simultaneously, resulting in high assembly efficiency. Through the design logic of step-by-step positioning, coordinated action, and precise transfer, a balance between efficiency and precision is achieved in the assembly of micro-parts. The sequential feeding of "long spring → bracket → springboard assembly" is adopted, and each component is precisely positioned at an independent workstation before entering the next stage, reducing assembly errors and improving assembly accuracy. The small disc, as a "mobile assembly platform," integrates three feeding steps with one unloading step to form a closed-loop subsystem, which is physically isolated from the main disc, reducing the interference of the main disc's vibration (during pressing assembly) on the long spring. The top feeding mechanism and the first clamping assembly form a "top-clamping" linkage, completing the clamping at the moment the long spring is lifted and detached from the placement seat, preventing the long spring from popping out due to elastic rebound.

[0026] The present invention further includes the following steps in step S4: S41: The bottom cover transfer mechanism sends the bottom cover on the bottom cover feeding guide rail into the bottom cover loading station of the assembly transfer guide rail; S42: The assembly transfer guide rail moves the bottom cover to the terminal piece feeding station, the terminal piece feeding guide rail feeds the terminal piece out from the opening, and the terminal piece transfer mechanism moves the terminal piece from the opening of the terminal piece feeding guide rail and inserts it into the bottom cover; S43: The assembly transfer guide rail moves the bottom cover and the terminal piece to the terminal piece riveting station, and the terminal piece riveting mechanism above rivets downward to make the terminal... The bottom cover is riveted to form a complete bottom cover; S44: The bottom cover flipping mechanism flips the bottom cover on the assembly transfer guide rail by 180 degrees; S45: The bottom cover finished product transfer mechanism moves the flipped bottom cover finished product to the bottom cover finished product feeding guide rail; S46: The bottom cover finished product feeding guide rail transports the flipped bottom cover finished product to the bottom cover assembly unloading station; S47: The short spring lifting mechanism lifts the short spring into the bottom cover assembly unloading station; S48: The bottom cover assembly transfer mechanism moves the bottom cover assembly and the short spring to the bottom cover assembly loading station simultaneously.

[0027] By adopting the above technical solution, from bottom cover loading (S41), terminal piece insertion (S42), riveting and fixing (S43) to flipping (S44), finished product transfer (S45-S46), and short spring assembly (S47-S48), each step corresponds to an independent workstation, avoiding cross-process interference. After the previous process is completed, the material is automatically transferred to the next workstation via the guide rail, reducing waiting time and manual transfer costs. The short spring lifting (S47) can be carried out in parallel with the bottom cover finished product conveying (S46), and the bottom cover component transfer mechanism (S48) simultaneously grabs the bottom cover and spring, shortening the single process cycle and making it suitable for mass continuous production. Each mechanism is only responsible for a single action (e.g., the "bottom cover flipping mechanism" only performs a 180-degree flip, and the "short spring lifting mechanism" focuses on spring positioning), simplifying equipment debugging and maintenance. "Linear flow + dedicated workstation + automated collaboration" achieves the production goal of "high efficiency, high precision, and low manual intervention", which is especially suitable for the mass manufacturing of standardized electronic components and provides stable quality assurance for subsequent final assembly processes.
