Description

Technical Field

[0001] This invention relates to a wire harness cutting and terminal assembly equipment and process for micro switch processing, belonging to the field of wire harness cutting and terminal assembly technology. Background Technology

[0002] Microswitches are high-precision, miniaturized contact switching components widely used in home appliances, automobiles, industrial control equipment, precision instruments, and other fields. The assembly quality of their internal wiring harnesses and terminals directly determines the conductivity stability, lifespan, and safety of the microswitch. In the mass production of microswitches, wiring harness cutting, end stripping, terminal crimping, and precise assembly are the core processing steps.

[0003] Currently, traditional micro switch wire harness terminal processing equipment on the market lacks a wire clamping and positioning mechanism, which cannot counteract the reverse sliding force generated by clamping. When processing short wire harnesses and thin wire harnesses for micro switches, due to the smooth outer sheath of the wire and the small gripping area between the terminal and the wire, the friction is insufficient, and the wire harness is very easy to slip backward under the clamping pressure, forming a half-inserted terminal. This defect can cause insufficient conductive contact area and increased contact resistance at the terminals. After the equipment is vibrating during operation, the terminals are prone to completely coming off, causing a circuit break. If the copper wires inside the wire harness retract with the wire and become misaligned, it can also cause short circuits between adjacent terminals and burn out electrical components such as microswitches. Summary of the Invention

The lifting column slides vertically through the top of the guide plate. The lower end of the lifting column is horizontally fixed to a lower pressure plate. Both ends of the lower pressure plate are equipped with lower pressure blocks.

The auxiliary anti-slip assembly includes an auxiliary pressure head. The bottom wall of the main pressure head has a rectangular groove facing upwards, and the auxiliary pressure head is slidably inserted into the rectangular groove. An anti-compression spring is fixedly installed on the top of the auxiliary pressure head, and the top of the anti-compression spring is fixed to the top wall of the rectangular groove. Anti-compression blocks are vertically fixed on both sides of the top wall of the auxiliary pressure head.

[0006] Preferably, mounting grooves are provided on the side walls of the two lower pressing blocks that are close to each other, and a rotating assembly roller is provided in each mounting groove. The roller rolls in contact with the inclined surfaces of the first trapezoidal body and the second trapezoidal body.

[0007] Preferably, a guide groove is formed in the top wall of the rectangular chute, and a guide rod is vertically fixed at the top of the auxiliary pressure head. The guide rod passes through the anti-compression spring upward and slides into the guide groove.

[0008] Preferably, the wire harness clamping and transporting assembly includes a guide post, a rectangular sleeve, and a spreading spring; the guide post is horizontally fixed inside the rectangular groove, the two ends of the guide post are slidably fitted with rectangular sleeves, the spreading spring is fitted in the middle of the guide post, the two ends of the spreading spring abut against the rectangular sleeves on both sides and drive the two sets of rectangular sleeves to move away from each other; a wire clamp is installed on the top of each rectangular sleeve, and the two wire clamps move towards each other to clamp the wire harness; several grooves are opened on the side walls of each wire clamp that are facing away from each other, and a cylinder is vertically rotated and assembled in each groove.

[0009] Preferably, the terminal pressing assembly includes a rod, a return spring, a force plate, and an elastic pressing block; the rod is vertically slidably inserted through the bent section of each group of L-shaped frames, the bottom ends of all rods are connected to the elastic pressing block, and the top ends of all rods are uniformly fixed to the bottom surface of the force plate; a return spring is sleeved on the outside of each rod, and the return spring is limited between the L-shaped frame and the force plate.

[0010] Preferably, extension plates are horizontally arranged on the top of the pressing table and on both sides of the terminal placement table. A third trapezoidal body is fixed on the opposite side of the two extension plates. The two third trapezoidal bodies cooperate to push the wire clamps on both sides to clamp the wire harness.

[0011] Preferably, the power assembly includes a servo motor, a disc wheel, and a push rod; the servo motor is mounted on the top wall of the support frame, and the output shaft of the servo motor passes through the outer wall of the support frame and is connected to the disc wheel; the edge of the disc wheel is rotatably connected to the push rod, and the end of the push rod is hinged to a lifting plate;

[0012] The bottom of the lifting plate is vertically fixed with a vertical rod, the lower end of which slides through the top of the guide plate and connects to the connecting seat. The bottom end of the connecting seat is fixed with the main pressure head.

[0013] The connecting seat is vertically mounted with a pressing column on the side away from the main pressure head. The pressing column moves downward to push the force plate down. The lifting column is vertically fixed to the bottom wall of the lifting plate on the side away from the vertical pole.

[0014] Preferably, the guide assembly includes a T-shaped block and a T-shaped groove; two horizontal T-shaped grooves are symmetrically opened on the top of the machine platform, and T-shaped blocks are symmetrically fixed at the bottom of the wire feeding table and the pressing table, with each T-shaped block slidably assembled in the corresponding T-shaped groove; The outer wall of the pressing table is symmetrically and horizontally fixed with spring rods. The ends of the spring rods are slidably inserted into the wire feeding table. Each spring rod is fitted with a separating spring, which is located between the wire feeding table and the pressing table.

[0015] Preferably, S1: The terminal feeding device places the metal terminal in the adapter groove at the top of the terminal placement platform, and the wire feeding device transports the stripped wire harness to the wire groove at the top of the wire harness guide platform, passes between the two sets of wire clamps, and stops feeding the wire after inserting the end of the stripped wire harness into the metal terminal halfway. S2: Start the servo motor to drive the disc wheel to rotate. The rotating disc wheel drives the push rod to pull the lifting plate down. The lowering lifting plate synchronously drives the lifting column and the vertical rod to move downward. The vertical rod drives the pressing column on the connecting seat to move down synchronously. The pressing column presses down on the force plate. The force plate drives the rod body and the elastic pressing block to move down synchronously, and performs non-pressing end pressing and fixing on the metal terminals on the terminal placement platform. S3: At the same time, the lifting column drives the lower pressure plate and the lower pressure block to move down synchronously. The lower pressure block pushes the first trapezoidal body and the second trapezoidal body closer to each other, thereby driving the wire feeding table and the pressing table to slide towards each other. During the process of the wire feeding table and the pressing table approaching each other, the third trapezoidal body on the two side extension plates squeezes the two sets of wire clamps to come closer to each other, clamps and positions the wire harness and keeps the wire harness pushed into the metal terminal. S4: When the terminal placement platform moves directly below the main pressure head, the auxiliary pressure head inside the main pressure head first descends at a constant speed to pre-press the wire harness and metal terminal, reducing the risk of wire harness slippage; after the top surfaces of the anti-pressure blocks on both sides of the auxiliary pressure head abut against the top wall inside the rectangular slide groove, the bottom wall of the main pressure head and the bottom surface of the auxiliary pressure head are flush and fit together, completing the overall pressing of the wire harness and terminal in one go; throughout the pressing process, the wire harness is continuously pressed and inserted into the inner wall of the terminal.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the linkage structure of the main anti-slip component and the wire harness clamping and conveying component, the wire feeding table and the pressing table are synchronously driven to feed in opposite directions during the pressing process. The wire clamp continuously clamps the wire harness and pushes it forward, which completely counteracts the reverse sliding force of the pressing. With the main pressing head built-in secondary anti-slip component to achieve pre-press locking of the wire, the upper and lower limits firmly fix the wire, and prevent the wire harness from retracting and slipping from the structural source. This ensures that the copper core is fully embedded in the terminal pressing area, which greatly improves the stability of conductive contact and reduces the risk of failure of the entire micro switch.

[0017] 2. The auxiliary anti-slip component uses an anti-compression spring to achieve segmented operation of first flexible pre-pressing and then rigid overall pressing. The elastic buffer absorbs instantaneous impact loads, avoiding workpiece brittleness. It can pre-press the terminals to be pressed, avoiding slippage during one-time rapid pressing production. At the same time, the guide rod and guide groove cooperate to constrain the auxiliary pressing head to move only vertically, without skew or one-sided extrusion problems. The pressing height and gripping force are highly consistent, which is suitable for batch processing of multi-diameter and multi-specification micro wire harness terminals, and significantly improves the yield rate.

[0020] 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.

[0021] Please see Figure 1-11 This invention provides a technical solution: a wire harness cutting and terminal assembly equipment and process for micro switch processing, including a machine base 1, a support frame 2 vertically installed on the top front side of the machine base 1, a power component installed on the top of the support frame 2, a guide plate 7 fixedly connected to the outer wall of the support frame 2, and a main pressure head 10 installed below the guide plate 7; a wire feeding table 12 and a pressing table 13 are slidably assembled on the top of the machine base 1 through the guide component, a wire harness guide table 33 and a terminal placement table 25 are respectively installed on the top of the wire feeding table 12 and the pressing table 13, a rectangular groove 28 is opened on the top of the wire feeding table 12, and two sets of L-shaped frames 20 are symmetrically and vertically arranged on the top of the pressing table 13; The guide plate 7 is equipped with the main anti-slip component; The main pressure head 10 is internally equipped with a secondary anti-slip component; The rectangular slot 28 is equipped with a wire harness clamping and conveying assembly; Both sets of L-shaped frames 20 are equipped with terminal pressing components; The main anti-slip assembly includes a lifting column 8, and the rear walls of the wire feeding platform 12 and the pressing platform 13 are respectively vertically fixed to the first trapezoidal body 14 and the second trapezoidal body 15. The lifting column 8 slides vertically through the top of the guide plate 7, and the lower end of the lifting column 8 is horizontally fixed to the lower pressure plate 16. The lower pressure plate 16 is equipped with lower pressure blocks 17 at both ends. The two lower pressure blocks 17 move down synchronously to drive the first trapezoidal body 14 and the second trapezoidal body 15 to move closer to each other. The auxiliary anti-slip assembly includes an auxiliary pressure head 37. The bottom wall of the main pressure head 10 has a rectangular groove 36 with the bottom wall facing upward. The auxiliary pressure head 37 is slidably inserted into the rectangular groove 36. An anti-compression spring 39 is fixedly installed on the top of the auxiliary pressure head 37. The top of the anti-compression spring 39 is fixed to the inner top wall of the rectangular groove 36. Anti-compression blocks 38 are vertically fixed on both sides of the top wall of the auxiliary pressure head 37. In an embodiment of the present invention, the servo motor 46 of the whole machine power assembly drives the disc wheel 3 to rotate continuously, and pulls the lifting plate 5 downward as a whole via the push rod 4. The lifting plate 5 synchronously drives the side lifting column 8 to move vertically downward. The lower end of the lifting column 8 is rigidly connected to the lower pressure plate 16, and the two ends of the lower pressure plate 16 are integrally assembled with lower pressure blocks 17 to press down vertically at the same time. During the downward movement of the lower pressure block 17, its inner roller 19 continuously adheres to the inclined surface of the first trapezoid 14 and the second trapezoid 15. Relying on the guide of the inclined surface, the vertically downward linear pressure is converted into horizontal opposing force components. The first trapezoidal body 14 on the rear wall of the wire feeding table 12 and the second trapezoidal body 15 on the rear wall of the pressing table 13 are pushed closer to each other. The wire feeding table 12 and the pressing table 13 slide smoothly in opposite directions in the T-shaped slide groove 45 of the machine base 1, relying on the bottom T-shaped block 44. When the lifting plate 5 is lifted upward with the rotary wheel 3, the lifting column 8 and the lower pressure plate 16 move upward synchronously. The lower pressure block 17 releases the pressure on the two sets of trapezoidal bodies. The outer platform spring 43 of the pressing table 13 releases its elasticity and pushes the return rod 42 to pull the wire feeding table 12 and the pressing table 13 apart and reset, completing one complete push-pull cycle. The core of anti-slip is: the crimping process simultaneously drives the wire harness and terminal station to move closer to each other, continuously applying a forward pushing pre-tightening force to the wire harness, which counteracts the reverse friction force of the wire harness retracting backward when the main pressure head 10 presses down, thus fundamentally solving the problems of terminal half-insertion and copper wire flying short circuit caused by the smooth outer skin and insufficient gripping force of the micro switch ultra-fine short wire harness.

[0022] The auxiliary anti-slip component is the core anti-slip and anti-pressure loss precision pressing structure of this equipment. It is integrated and assembled inside the main pressure head 10. It mainly consists of a rectangular slide groove 36, an auxiliary pressure head 37, an anti-pressure block 38, and an anti-pressure spring 39. The bottom wall of the main pressure head 10 is recessed upward to form a rectangular slide groove 36, which provides vertical sliding limit space for the auxiliary pressure head 37. The auxiliary pressure head 37 is vertically slidably inserted into the rectangular slide groove 36 and can extend and retract independently relative to the main pressure head 10. The top end face of the auxiliary pressure head 37 is fixedly equipped with an anti-pressure spring 39. The top end of the anti-pressure spring 39 is fixedly connected to the inner top wall of the rectangular slide groove 36, which can continuously provide downward elastic support force for the auxiliary pressure head 37. Two sets of anti-pressure blocks 38 are also symmetrically fixed vertically on the left and right sides of the top wall of the auxiliary pressure head 37 to limit the maximum retraction stroke of the auxiliary pressure head 37 and realize the dual-mode switching of elastic pre-pressure and rigid final pressure. This component works synchronously with the equipment's power components, following the main pressure head 10's pressing, holding, and resetting movements. During the initial standby phase, the anti-compression spring 39 is in a naturally extended, uncompressed state. Under the elastic pushing action of the anti-compression spring 39, the auxiliary pressure head 37 extends downwards from inside the rectangular groove 36 of the main pressure head 10, with the bottom surface of the auxiliary pressure head 37 lower than the bottom surface of the main pressure head 10. The anti-compression block 38 maintains a safe distance from the inner top wall of the rectangular groove 36, reserving sufficient elastic buffer stroke. During the elastic pre-compression transmission phase, the servo motor 46 drives the main pressure head 10 downwards at a uniform speed. The auxiliary pressure head 37 first contacts the workpiece combining the wire harness and the micro-terminal. The workpiece's reverse support resistance pushes the auxiliary pressure head 37 vertically upwards along the inner wall of the rectangular groove 36, compressing the anti-compression spring 39. The anti-compression spring 39 forms a uniform, flexible pressure to slowly pre-compress the wire harness terminals, continuously counteracting the reverse friction caused by the wire harness slipping and retracting during the compression process. Force ensures accurate pre-pressing position. After entering the rigid final press transmission stage, the main pressure head 10 continues to descend, driving the auxiliary pressure head 37 to retract continuously until the top surfaces of the anti-pressure blocks 38 on both sides of the auxiliary pressure head 37 tightly abut against the inner top wall of the rectangular slide groove 36. The anti-pressure blocks 38 form a mechanical limit lock to stop the retraction stroke of the auxiliary pressure head 37. The anti-pressure spring 39 reaches the maximum compression and no longer deforms. The downward pressure of the main pressure head 10 is rigidly transmitted through the anti-pressure blocks 38, so that the bottom surfaces of the main pressure head 10 and the auxiliary pressure head 37 form a flat integral pressing surface, completing the rigid pressing and forming of the wire harness and terminal in one go. After the pressing process is completed, the main pressure head 10 is raised with the lifting plate 5. The auxiliary pressure head 37 is separated from the workpiece and loses the reverse support force. The anti-pressure spring 39 in the compressed state releases elastic potential energy, pushing the auxiliary pressure head 37 down along the rectangular slide groove 36 to reset. The anti-pressure blocks 38 are removed from the limit, and the component returns to the initial standby state, completing a single complete transmission cycle. This structure boasts multiple technological advantages. Firstly, it employs a graded pressing logic of elastic pre-pressing followed by rigid final pressing, which specifically addresses industry pain points such as the smooth outer sheath, low coefficient of friction, and easy slippage during crimping of ultra-fine short wire harnesses in microswitches. It continuously counteracts reverse sliding force, eliminating short-circuit and burn-out faults caused by terminal half-insertion, insufficient conductive contact, equipment vibration open circuit, and copper wire flyaways. Secondly, the elastic buffering effect of the anti-compression spring 39 can completely absorb the instantaneous pressing impact force, avoiding damage problems such as cracking, shearing, crimping collapse, and dimensional deviations of micro thin-walled terminals and thin copper wires. While ensuring the crimping firmness, it significantly reduces the workpiece scrap rate. Simultaneously, relying on the vertical limiting of the rectangular slide 36 and the symmetrical limiting of the double-sided anti-pressure blocks 38, the auxiliary pressure head 37 can be strictly constrained to only make vertical linear movements, completely eliminating the problems of offset, tilting, and bias pressure. This effectively ensures the consistency of the pressing coaxiality, pressing height, and gripping force, and is suitable for the harsh working conditions of high-frequency start and stop of micro switches. In addition, the anti-pressure spring 39 has a stable elastic deformation range, which can adapt to the small tolerance fluctuations of wire harness diameter and terminal thickness. It can adapt to the processing of multi-specification micro wire harnesses and micro terminals without changing the mold, effectively improving the versatility of the equipment and reducing the maintenance cost. Furthermore, the components are integrated into the main pressure head 10, without external transmission structure, small space occupation, and no structural interference. The entire process relies on spring deformation and mechanical limiting to complete the action, without the need to add additional drive and sensing components. The structure is simple, with few failure points, low operating noise, and low wear. It can carry out automated continuous operation stably for a long time, effectively improving the production cycle and batch production stability of the equipment.

[0023] Please see Figure 4 Furthermore, mounting grooves 18 are provided on the side walls of the two lower pressing blocks 17 that are close to each other. Each mounting groove 18 contains a rotating assembly roller 19, which rolls against the inclined surfaces of the first trapezoidal body 14 and the second trapezoidal body 15. In an embodiment of the present invention, when the lifting column 8 drives the lower pressure plate 16 and the lower pressure block 17 to move downward, the roller 19, which can rotate freely in the mounting groove 18 of the lower pressure block 17, is always in close contact with the inclined surfaces of the first trapezoidal body 14 and the second trapezoidal body 15. During the continuous downward pressure of the lower pressure block 17, the roller 19 rotates autonomously with the relative displacement of the inclined surfaces, maintaining rolling friction contact throughout the process. When the lifting plate 5 is raised and the lower pressure block 17 is disengaged from the first trapezoidal body 14 and the second trapezoidal body 15, the roller 19 no longer bears the load. The wire feeding table 12 and the pressing table 13 separate from each other under the action of the separating spring 43. The inclined surfaces of the first trapezoidal body 14 and the second trapezoidal body 15 are completely separated from the roller 19 without friction or scratching. In long-term batch operations, the roller 19 can disperse the concentrated contact stress of the lower pressure block 17, avoid single-point heavy pressure forming indentations and depressions on the inclined surfaces of the first trapezoidal body 14 and the second trapezoidal body 15, and ensure that the inclination angle of the inclined surface remains unchanged over a long period of time; the roller 19 is made of wear-resistant metal material and can be disassembled and replaced individually without the need to replace the lower pressure block 17 and the first trapezoidal body 14 and the second trapezoidal body 15 as a whole.

[0024] Extending equipment lifespan: The coefficient of rolling friction is much lower than that of sliding friction, reducing the wear rate of the first trapezoid 14, the second trapezoid 15, and the lower pressure block 17, thus reducing dimensional deviations caused by long-term mass production. Smooth and uninterrupted transmission: The roller 19 rotates adaptively to the inclined plane angle, avoiding jamming and shutdown of the wire feeding table 12 and pressing table 13 caused by burrs and wear protrusions on the inclined plane, and significantly improving the stability of continuous operation of the equipment. Reduced maintenance costs: Roller 19 is a small standard part that can be disassembled and replaced separately after wear, eliminating the need to replace the entire set of lower pressure plate 16, first trapezoid 14, and second trapezoid 15, thus significantly reducing spare parts procurement and downtime for maintenance. Uniform pressure output: The roller 19 linearly contacts and disperses the pressure, the first trapezoid 14 and the second trapezoid 15 will not undergo local deformation, the push and pull stroke of the wire feeding table 12 and the pressing table 13 remains uniform over a long period of time, and the wire harness pushing force is stable.

[0025] Please see Figure 11 Furthermore, a guide groove 41 is provided on the inner top wall of the rectangular chute 36, and a guide rod 40 is vertically fixed at the top of the auxiliary pressure head 37. The guide rod 40 passes through the anti-compression spring 39 upward and slides into the guide groove 41. In an embodiment of the present invention, the downward movement of the lifting plate 5 drives the vertical rod 6, the connecting seat 9, and the main pressure head 10 to move downward as a whole. The auxiliary pressure head 37 contacts the wire harness and terminal assembly before the bottom surface of the main pressure head 10. The wire harness terminal generates a reverse supporting force to push the auxiliary pressure head 37 upward. The auxiliary pressure head 37 slides upward along the rectangular slide groove 36 inside the main pressure head 10 to compress the anti-compression spring 39. The top guide rod 40 of the auxiliary pressure head 37 simultaneously passes through the anti-compression spring 39 and moves vertically along the guide groove 41 on the top wall of the rectangular slide groove 36. The sliding limit restricts the lateral displacement of the auxiliary pressure head 37. After the auxiliary pressure head 37 is pressed down until the top surface of the anti-pressure blocks 38 on both sides of the auxiliary pressure head 37 is pressed against the inner top wall of the rectangular slide groove 36, the auxiliary pressure head 37 stops retracting. The bottom surface of the main pressure head 10 and the bottom surface of the auxiliary pressure head 37 form a complete and flush pressing surface, which together completes the final pressing and forming of the terminal wire harness. After the lifting plate 5 is raised, the anti-pressure spring 39 releases its elastic force and pushes the auxiliary pressure head 37 down to reset. The guide rod 40 slides down along the guide groove 41 to return to its position, waiting for the next pre-pressing process.

[0026] Graded crimping to prevent breakage: First, elastic pre-compression buffers the impact, then rigid overall crimping, to avoid defects such as terminal cracking, copper wire shearing, and crimping height exceeding tolerance caused by instantaneous hard impact on micro-switch micro terminals and ultra-fine copper wires; Precise crimping alignment: The guide rod 40 and the guide groove 41 work together to achieve dual-dimensional positioning, the auxiliary crimping head 37 does not wobble left or right, and the pre-pressing and final pressing are always aligned with the center of the terminal inside the terminal placement platform 25, eliminating poor conductivity caused by bias. Pressure Adaptive: The compression spring 39 provides an elastic buffer zone to accommodate small tolerances in wire diameter. Wires with slight differences in thickness can all obtain uniform preload, improving the consistency of finished products. Double anti-slip: During the pre-pressing stage, the auxiliary pressure head 37 presses the wire harness terminal in advance, and together with the wire harness clamping and conveying component below, it forms a double limit at the top and bottom, completely preventing the wire harness from slipping backward during the pressing moment.

[0027] Please see Figure 9 Furthermore, the wire harness clamping and transport assembly includes a guide post 29, a rectangular sleeve 30, and a spreading spring 31; the guide post 29 is horizontally fixed inside the rectangular groove 28, and the rectangular sleeves 30 are slidably fitted at both ends of the guide post 29. The spreading spring 31 is fitted in the middle of the guide post 29, and the two ends of the spreading spring 31 abut against the rectangular sleeves 30 on both sides and drive the two sets of rectangular sleeves 30 to move away from each other; a wire clamp 32 is installed on the top of each rectangular sleeve 30, and the wire clamps 32 on both sides move towards each other to clamp the wire harness; several grooves 34 are opened on the side walls of each wire clamp 32 that are facing away from each other, and a cylinder 35 is vertically rotated and assembled in each groove 34; In an embodiment of the present invention, the wire feeding platform 12 and the pressing platform 13 move towards each other under the thrust of the main anti-slip component. The third trapezoidal body 27 on the top extension plate 26 of the pressing platform 13 moves forward synchronously, and the inclined surface presses the cylinder 35 in the groove 34 on the outer side of the wire clamps 32 on both sides. The cylinder 35 is driven by the thrust of the inclined surface to slide the rectangular sleeve 30 horizontally towards each other along the guide post 29. The two sets of rectangular sleeves 30 synchronously compress the middle spreading spring 31, and the top wire clamp 32 synchronously retracts inward, thus aligning the wire bundle. The wire harness passing through the guide table 33 is clamped in a ring around its outer periphery; the cylinder 35 on the wire clamp 32 can rotate freely and maintain rolling contact with the inclined surface of the third trapezoidal body 27, so that the wire harness insulation will not be scratched during the clamping process; when the crimping is completed and the wire feeding table 12 and the crimping table 13 separate from each other, the third trapezoidal body 27 disengages from the outside of the wire clamp 32, the spring 31 rebounds and pushes the rectangular sleeves 30 on both sides away from each other, and the wire clamp 32 automatically opens to release the wire harness, completing a single clamping and releasing cycle.

[0028] Continuous feeding and anti-slip: The clamping mechanism of wire clamp 32 moves forward synchronously with the wire feeding table 12, and continuously pushes the wire harness into the terminal placement table 25 to counteract the reverse pulling force of crimping, thus solving the problems of high friction, wire displacement, and deformation and failure of waterproof plug when assembling wire harnesses with waterproof plugs. Strong wire protection: The 35° rotatable cylinder replaces the hard metal clamp, and there are no sharp edges to scratch or cut the wire harness insulation layer when clamping. It is compatible with micro switches with ultra-thin insulation and ultra-fine wires. Adaptive clamping stroke: The expansion spring 31 provides elastic clamping force, which can stably clamp wire harnesses with different outer diameters without the need for manual replacement of the clamping mold; Cost-saving linkage drive: Clamping is automatically achieved by the relative motion of the wire feeding table 12 and the pressing table 13, eliminating the need for independent cylinders and servo grippers, reducing pneumatic components and control points, and simplifying the structure of the machine 1.

[0029] Please see Figure 7 Furthermore, the terminal pressing assembly includes a rod 21, a return spring 22, a force plate 23, and an elastic pressing block 24; the rod 21 is vertically slidably inserted through the bent section of each L-shaped frame 20, the bottom ends of all rods 21 are connected to the elastic pressing block 24, and the top ends of all rods 21 are uniformly fixed to the bottom surface of the force plate 23; a return spring 22 is sleeved on the outside of each rod 21, and the return spring 22 is limited between the L-shaped frame 20 and the force plate 23; In an embodiment of the present invention, the lifting plate 5 moves downward, causing the vertical rod 6 and the connecting seat 9 to move downward simultaneously. The pressing column 11 on the side of the connecting seat 9 pushes the top surface of the force plate 23 vertically downward. After the force plate 23 is subjected to force, it causes multiple rods 21 to slide vertically downward along the bending section of the L-shaped frame 20, simultaneously compressing the return spring 22 on the periphery of the rods 21. The elastic pressing blocks 24 connected to the bottom of all rods 21 descend simultaneously, pressing the non-crimping area of ​​the metal terminal tail in the slot of the terminal placement platform 25, limiting the vertical and horizontal displacement of the terminal. After the main pressing head 10 completes the crimping of the wire harness terminal, the lifting plate 5 rises upward with the rotary rotation of the disc wheel 3. The pressing column 11 moves upward simultaneously to release the pressure on the force plate 23. The return spring 22 releases its elastic force to lift the force plate 23 upward, causing the rods 21 and the elastic pressing blocks 24 to rise simultaneously, releasing the terminal and completing the terminal fixing cycle.

[0030] Zero offset terminal positioning: The terminal tail is locked throughout the crimping process to prevent the terminal from being lifted or slipping under the pressure when the main crimping head 10 is pressed down. This ensures that the copper core of the wire harness and the crimping area of ​​the terminal are accurately aligned, eliminating poor connection, bias pressure and terminal deformation. Elastic buffer protection for miniature terminals: The elastic pressing block 24 has the ability to buffer deformation, and the hard contact pressure is absorbed to prevent the ultra-thin miniature terminals of micro switches from cracking, bending and becoming unusable due to pressure. Multi-rod synchronous transmission ensures uniform force distribution: The double L-shaped frame 20 is paired with multiple rods 21 for synchronous drive, and the elastic pressing block 24 is subjected to balanced force, preventing one-sided pressing or one-sided warping. Simplified power reuse system: Shares the top servo motor 46 downward pressure power locking terminal, eliminating the need for a separate terminal clamping cylinder, shortening the overall machine operation sequence, and improving production cycle time.

[0031] Please see Figure 7 Furthermore, extension plates 26 are horizontally arranged on the top of the pressing table 13 and on both sides of the terminal placement table 25. The two extension plates 26 are fixed with third trapezoidal bodies 27 on opposite sides. The two third trapezoidal bodies 27 cooperate to push the wire clamps 32 on both sides to clamp the wire harness in opposite directions. In an embodiment of the present invention, the pressing table 13 is pushed horizontally toward the wire feeding table 12 by the second trapezoidal body 15, and the extension plates 26 on both sides of the pressing table 13 move forward synchronously with the table body. The inclined surface of the third trapezoidal body 27 fixed at the end of the extension plate 26 gradually fits against the outer cylinder 35 of the wire clamp 32. As the distance between the wire feeding table 12 and the pressing table 13 continues to decrease, the inclined surface of the third trapezoidal body 27 continues to squeeze the cylinder 35. The squeezing force increases linearly with the distance between the two tables, driving the wire clamps 32 on both sides to gradually tighten the wire bundle, realizing the integrated linkage action of the workstation approaching, synchronous clamping and continuous pushing. When the crimping process is completed, the wire feeding table 12 and the crimping table 13 move away from each other under the action of the separating spring 43. The third trapezoidal body 27 retracts with the extension plate 26, the inclined surface separates from the wire clamp 32 cylinder 35, the spreading spring 31 pushes the wire clamp 32 to open, and the processed wire bundle is released, waiting for the next set of wires to be fed.

[0032] Shorten processing cycle time: Clamping, pushing and terminal fixing are performed simultaneously without the need for separate steps, which greatly shortens the processing cycle of a single wire harness and increases the overall production capacity of machine 1. No independent drive components, reducing the number of failure points: Clamping is achieved entirely by the relative sliding of the wire feeding table 12 and the pressing table 13, eliminating the need for accessories such as clamping cylinders, solenoid valves, and air pipes, thus reducing failures such as air leakage and valve damage. Adaptable to processing of multiple specifications of wire harnesses: By simply adjusting the maximum stroke of the wire feeding table 12 and the pressing table 13, it can adapt to micro switch wire harnesses of different lengths, making the equipment more versatile.

[0033] Please see Figure 2 Furthermore, the power components include a servo motor 46, a disc wheel 3, and a push rod 4; the servo motor 46 is mounted on the top wall of the support frame 2, and the output shaft of the servo motor 46 passes through the outer wall of the support frame 2 and is connected to the disc wheel 3; the edge of the disc wheel 3 is rotatably connected to the push rod 4, and the end of the push rod 4 is hinged to the lifting plate 5; The bottom of the lifting plate 5 is vertically fixed to the vertical rod 6. The lower end of the vertical rod 6 slides through the top of the guide plate 7 and connects to the connecting seat 9. The bottom end of the connecting seat 9 is fixed to the main pressure head 10. A pressing column 11 is vertically installed on the side of the connecting seat 9 away from the main pressing head 10. The pressing column 11 moves downward to push the force plate 23 downward. The lifting column 8 is vertically fixed to the bottom wall of the lifting platform 5 on the side away from the vertical bar 6; In an embodiment of the present invention, the servo motor 46 at the top of the support frame 2 receives a PLC numerical control signal and rotates at a uniform speed. The output shaft drives the disc wheel 3 to rotate synchronously. The edge of the disc wheel 3 is eccentrically hinged to the push rod 4, and the eccentric rotational motion is converted into the vertical linear motion of the push rod 4 reciprocatingly pushing and pulling the lifting plate 5. When the lifting plate 5 moves downward, it synchronously drives the three actuators to work: the first lifting column 8 drives the main anti-slip component to bring the wire feeding table 12 and the pressing table 13 together and clamp and push the wire harness; the second vertical rod 6 drives the connecting seat 9, the main pressing head 10, and the auxiliary pressing head 37 to perform graded pre-pressing and final pressing; the third pressing column 11 presses down the terminal pressing component to lock the metal terminal in the terminal placement table 25; when the disc wheel 3 rotates to the eccentric high position, the push rod 4 pulls the lifting plate 5 upward as a whole, the three actuators synchronously release pressure, and all spring components rebound and reset, completing a complete set of processing action cycles; the servo motor 46 can be precisely adjusted in terms of speed, pressing stroke, and holding time through the program to match the processing requirements of different specifications of terminal wire harnesses.

[0034] Single-power multi-path synchronous drive: Only one set of servo motors can synchronously complete the three core processes of terminal fixing, wire harness clamping and pushing, and graded crimping, eliminating the need for multiple independent servo motors and cylinders, and significantly reducing the manufacturing cost and electrical control complexity of the machine tool. The action sequence is highly synchronized, resulting in high product consistency: the three processes start, hold pressure, and reset synchronously, with no time difference in wire harness clamping, terminal fixing, and crimping actions, preventing defects such as pressing before loosening or clamping before shifting. Servo precision and controllability, suitable for micro-machining: The servo motor 46 closed-loop control of the pressing stroke and pressure accurately matches the crimping height standard of micro-switches, ultra-fine wires, and micro-terminals, resulting in minimal pressure fluctuation and a significant reduction in online quality inspection defect rate; Continuous automated cycle operation: The disc wheel 3 rotates continuously to achieve uninterrupted feeding, processing and unloading, without the need for manual step-by-step operation, and is suitable for mass production line production.

[0035] Please see Figure 5 Furthermore, the guide assembly includes T-shaped blocks 44 and T-shaped slides 45; two horizontal T-shaped slides 45 are symmetrically opened on the top of the machine base 1, and T-shaped blocks 44 are symmetrically fixed at the bottom of the wire feeding table 12 and the pressing table 13, and each T-shaped block 44 is slidably assembled in the corresponding T-shaped slide 45. The outer wall of the pressing table 13 is symmetrically and horizontally fixed with spring rods 42. The ends of the spring rods 42 are slidably inserted into the wire feeding table 12. Each spring rod 42 is fitted with a separating spring 43. The separating spring 43 is located between the wire feeding table 12 and the pressing table 13. In an embodiment of the present invention, T-shaped blocks 44 are symmetrically fixed at the bottom of the wire feeding table 12 and the pressing table 13. The T-shaped blocks 44 are inserted into the two horizontal T-shaped sliding grooves 45 on the top surface of the machine table 1. When the lower pressing block 17 squeezes the first trapezoidal body 14 and the second trapezoidal body 15 to generate a horizontal thrust, the T-shaped blocks 44 slide smoothly horizontally along the T-shaped sliding grooves 45. The T-shaped structure restricts the wire feeding table 12 and the pressing table 13 from tilting up and down, flipping left and right, and shifting forward and backward. Symmetrical spring rods 42 are mounted on the outer side of the pressing table 13. The spring rods 42 slide into the inside of the wire feeding table 12. The split spring 43 is sleeved on the outside of the spring rod 42, with its two ends abutting against the side walls of the wire feeding table 12 and the pressing table 13, respectively. When the lifting column 8 moves upward to relieve pressure and the lower pressing block 17 stops pressing the first trapezoidal body 14 and the second trapezoidal body 15, the split spring 43, which is in a compressed state, releases its elastic potential energy, pulls the spring rod 42 to slide outward, and drives the wire feeding table 12 and the pressing table 13 to separate from each other along the T-shaped slide 45, automatically resetting to the initial feeding position, reserving operating space for the next round of wire harness and terminal feeding. The entire resetting process is completed by the elastic force of the split spring 43, without the need for additional driving components.

[0036] Ultra-high alignment accuracy: T-shaped slide 45 provides all-round limit, the wire feeding table 12 and pressing table 13 have no up-down or left-right wobbling, the wire harness guide table 33 and terminal placement table 25 have stable coaxiality, and there will be no alignment deviation during long-term processing, reducing terminal bias failure. Automatic reset eliminates the need for a pneumatic reset mechanism: The station automatically returns to its original position by relying on the split spring 43, eliminating the need for a reset cylinder and solenoid valve, simplifying the air circuit layout of machine tool 1, reducing equipment failure rate, and shortening the single processing cycle time. Smooth and wear-resistant sliding operation: The large contact area between the T-block 44 and the T-groove 45 results in low pressure per unit area, slow wear during long-term reciprocating sliding, and long-term stable dimensional accuracy of the equipment. Safety anti-collision limit: The two ends of the T-shaped slide 45 form mechanical limit to prevent the wire feeding table 12 and the pressing table 13 from sliding and colliding with the bearing frame 2, the main pressing head 10 and other precision molds and pressing heads, thus extending the service life of core components.

[0037] The workflow of this embodiment is as follows: The power mechanism drives the lifting plate downward, causing the main pressure head 10 to feed downward as a whole. The auxiliary pressure head 37 extends longer than the main pressure head 10, so the auxiliary pressure head 37 will first contact the wire harness and terminal assembly placed above the terminal placement platform. The workpiece generates an upward supporting reaction force on the auxiliary pressure head 37, forcing the auxiliary pressure head 37 to slide vertically upward along the rectangular slide groove 36 inside the main pressure head 10. During the upward movement, the auxiliary pressure head 37 continuously compresses the anti-compression spring 39 at the top. After being compressed, the anti-compression spring 39 generates downward elastic pressure, causing the auxiliary pressure head 37 to press the wire harness tightly, forming a pre-clamping effect, firmly locking the wire, offsetting the reverse pull generated by the subsequent rigid downward pressure, and effectively preventing the wire harness from shrinking and slipping backward. Under the constraint of the rectangular slide 36, the auxiliary pressure head 37 can only move in a vertical straight line, without swaying left or right or shifting laterally, ensuring that the pre-pressure point is always aligned with the center of the terminal. As the main pressure head 10 continues to move downward, the auxiliary pressure head 37 continuously retracts upward until the anti-pressure blocks 38 on both sides of the top of the auxiliary pressure head 37 are tightly pressed against the inner top wall of the rectangular slide 36. At this point, the auxiliary pressure head 37 is mechanically limited and cannot continue to retract upward, and the anti-pressure spring 39 no longer compresses further. The downward pressure of the main pressure head 10 will be directly transmitted to the auxiliary pressure head 37 through the pressure-resistant block 38. The bottom surface of the main pressure head 10 and the bottom surface of the auxiliary pressure head 37 form a complete planar pressure head, which completes the pressing process of the wire harness copper core and the metal terminal with constant rigid pressure. After the crimping process is completed, the lifting plate is raised, the main pressing head 10 is removed from the workpiece, the auxiliary pressing head 37 loses the support resistance of the workpiece, the compression spring 39 in the compressed state releases elastic potential energy, and pushes the auxiliary pressing head 37 downward along the rectangular slide groove 36. The compression block 38 separates from the top wall of the slide groove, the auxiliary pressing head 37 extends automatically, and the entire auxiliary anti-slip assembly returns to the initial standby state, ready to carry out the next round of wire harness terminal crimping operation. This workflow is divided into two stages: elastic pre-tightening and rigid crimping. The pre-tightening process securely fixes the wire harness in advance, solving the problem of incomplete terminal insertion caused by wire slippage. The spring buffer weakens the instantaneous impact load, preventing micro-terminal cracking and cutting of ultra-fine copper wires. The vertical slide ensures that the auxiliary crimping head always moves vertically downward, eliminating poor bias pressure. This ensures that the crimping size and crimping force of each product remain highly consistent during mass production, significantly reducing the defect rate.
