Description

Technical Field

[0001] This invention relates to the field of welding fixture structure technology, specifically to a high-speed wire clamp fixture. Background Technology

[0002] The use of high-speed data transmission cables is growing. As the demand for connectivity increases, high-speed cables are needed to provide connections between different devices, such as routers and switches.

[0003] Currently, the commonly used jigs for stripping and processing high-speed data transmission cables are 180° planar jigs or separate small wire clamps for turnover. However, since the motherboard of the high-speed equipment to be soldered requires wire bonding on both sides, the disadvantage of using traditional wire clamps is that it requires changing the clamp twice, processing the two rows of wires twice, and manually flipping them, which is also more troublesome. In addition, the large clamp angle makes the wires prone to pulling and bending under force, making it difficult to position accurately, which affects the subsequent cutting, stripping and soldering quality to the circuit board.

[0004] Later, some wire welding fixtures emerged that could position the double-row core wires of the wire separately. In this way, the processing of double-row core wires could be completed on the same wire positioning fixture. However, this only solved the shortcomings of traditional wire clamps by increasing the number of workstations, but did not fundamentally solve the practical problems. For example, when processing materials of different specifications and quantities at multiple angles, it is still necessary to change to different specifications of fixtures to complete secondary processing. Therefore, the practicality of the welding fixtures is poor, which affects work efficiency.

[0005] To address the aforementioned issues, a Chinese utility model patent with publication number "CN216503058U" entitled "An Adjustable and Replaceable Welding Fixture" discloses a welding fixture comprising a fixture body and a wire clamping fixture positioning base and a connector base detachably mounted on the fixture body. The wire clamping fixture positioning base and the connector base are arranged front-to-back on the fixture body. The wire clamping fixture positioning base is adjustable front-to-back relative to the fixture body. A wire clamping fixture mounting position is provided on the wire clamping fixture positioning base, and a wire clamping fixture cover is provided above the mounting position. The wire clamping fixture cover is rotatable and can be opened and closed left-to-right relative to the wire clamping fixture positioning base. The connector base is adjustable left-to-right relative to the fixture body. Thus, by allowing the wire clamping fixture positioning base to be adjustable front-to-back relative to the fixture body and the connector base to be adjustable left-to-right relative to the fixture body, the fixture can be flexibly adjusted and partially replaced. This fixture can clamp multiple rows of high-speed wires, significantly improving welding efficiency in high-speed wire welding operations.

[0006] However, this fixture also has some problems. First, it operates on a single-sided clamping method. While single-sided clamping is relatively simple, the clamping effect is difficult to control. Over-clamping may damage the clamped high-speed wire, while under-clamping may result in better performance on the surface high-speed wire, but the lower-layer high-speed wires may shift during processing, affecting the welding effect. Second, although this fixture allows for some adjustment, high-speed wire clamping fixtures involve more than just clamping and fixing; they may also involve clamping the adhesive blocks and separating the wires. However, this fixture can only perform wire separating and clamping operations, and cannot clamp the adhesive blocks. Furthermore, this fixture is difficult to handle when performing multi-layer wire welding processes. When multiple products are moved, the clamped wires may shift in position, causing welding or other processes to be performed in a position that is not ideal. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the aforementioned background technology and provide a high-speed wire clamping fixture.

[0008] The technical solution of this invention is: a high-speed wire clamping fixture, comprising, Cable clamp base; Multiple sets of rocker arms are spaced apart along the X direction, each set including two rocker arms arranged opposite each other along the Z direction; the rocker arms are arranged along the Y direction, one end of which is hinged to the wire clamping base and can rotate around the X-axis, and the other end is limited by the limiting structure on the wire clamping base when flipped to the horizontal state; when the two rocker arms in the same set are flipped to the horizontal state, the wire between them is locked.

[0009] According to the present invention, a high-speed wire clamping fixture is provided, wherein the limiting structure includes a limiting buckle that is rotatably hinged to the wire clamping base about the X-axis; one end of the limiting buckle is pressed against the end of the rocker arm when the rocker arm is flipped to a horizontal state, and a tension spring is provided between the other end and the wire clamping base.

[0010] According to the present invention, a high-speed wire clamping fixture is provided, wherein a first magnet that repels each other is provided between the clamping base and the rocker arm.

[0011] According to the present invention, a high-speed wire clamping fixture is provided, wherein the rocker arm includes a first rocker arm for separating wires; a wire pressing plate is provided on the side of the first rocker arm facing the other side of the same group; and the wire pressing plate is provided with a plurality of spaced wire grooves adapted to individual wires.

[0012] According to the present invention, a high-speed wire clamping fixture is provided in which the two ends of the wire clamping plate are rotatably hinged to a first rocker arm about the Y-axis. The wire clamping plate has a flat end face on one side of the back of the wire groove. The flat end face will not interfere with the wire when the wire clamping plate is flipped to face the wire.

[0013] According to a high-speed wire clamping fixture provided by the present invention, the first rocker arm is provided with a limiting post that restricts the wire clamping plate from continuing to rotate when the wire clamping plate is rotated to a flat end face that fits against the first rocker arm; a ball head is provided at one end of the limiting post facing the wire clamping plate.

[0014] According to a high-speed wire clamping fixture provided by the present invention, a second magnet is provided between the first rocker arm and the wire clamping plate, which attracts the wire clamping plate to the first rocker arm when the wire clamping plate is flipped to face the wire groove side.

[0015] According to a high-speed wire clamping fixture provided by the present invention, the rocker arm further includes a second rocker arm for pressing and limiting the rubber block on the wire; the second rocker arm has a contour block that conforms to the shape of the rubber block on one side facing the other side of the same group of second rocker arms, the second rocker arm and the first rocker arm are arranged at intervals along the X direction, and the second rocker arm is located on the side behind the first rocker arm in the X direction.

[0016] According to the present invention, a high-speed wire clamping fixture is provided, wherein a plurality of detachable contour blocks are arranged sequentially along the Y direction on the second rocker arm.

[0017] According to a high-speed wire clamping fixture provided by the present invention, the rocker arm further includes a third rocker arm for clamping and limiting the wire; the third rocker arm and the second rocker arm are arranged at intervals along the X direction, and the third rocker arm is located on the rear side of the second rocker arm in the X direction.

[0018] The advantages of this invention are as follows: 1. This invention relates to a high-speed wire clamping fixture. The wire clamping fixture of this invention uses two rocker arms arranged opposite each other along the Z-direction to clamp the wire. This double-sided clamping method, compared with single-sided clamping, can apply clamping forces of equal magnitude and opposite direction on both sides of the wire, making the force on the wire extremely balanced in the X-direction (i.e., the wire extension direction), fundamentally avoiding wire bending, deformation or positional displacement that may be caused by single-sided clamping, ensuring the stability and reliability of clamping, applicable to various scenarios, effectively resisting the inertial force generated by equipment movement, and ensuring the positional accuracy of the wire; the wire clamping fixture of this invention adopts modular grouping, adapting to multi-line parallel processing, and multiple groups The structure, arranged at intervals along the X-axis, allows the fixture to clamp multiple parallel wires simultaneously. This modular grouping design greatly improves production efficiency, meets the needs of industrial batch processing, and the independence between groups ensures that the clamping forces of each group do not interfere with each other. The wire clamping fixture of this invention is easy to operate and has a clear state. The rocker arm rotates around the X-axis to achieve flipping and opening, and the limiting structure locks the horizontal working state, forming a very intuitive and convenient mechanical structure. The operator only needs to flip the rocker arm to the limit position to complete the clamping, without complicated locking operations. Moreover, the limiting structure can clearly indicate the clamping status, reducing the possibility of misoperation.

[0019] 2. The limiting structure of this invention can adaptively tighten, eliminating gaps. It employs a combination of a limiting buckle and a tension spring to form an elastic limiting system. When the rocker arm is rotated to a horizontal position, the limiting buckle automatically tightens at the end of the rocker arm under the spring tension. The spring's preload absorbs machining and assembly tolerances, ensuring tight contact between the buckle and the rocker arm end regardless of minute gaps, eliminating potential wobbling in rigid limiting and further enhancing clamping stability. The limiting buckle offers clear tactile feedback and high reliability. The tension spring provides clear resistance feedback to the operator when engaging and disengaging the buckle, providing a distinct tactile feel. Simultaneously, the spring force consistently acts on the buckle, maintaining its tightening tendency and preventing it from loosening even under vibration, significantly improving the reliability of the fixture under high-speed movement or vibration conditions.

[0020] 3. This invention introduces mutually repelling first magnets to assist in opening, improving operational efficiency. By setting mutually repelling magnets between the rocker arm and the wire clamp base, when the constraint of the limiting buckle is released, the magnetic force will immediately push the rocker arm to automatically spring up, achieving rapid opening. This eliminates the operator's need to manually open the rocker arm, which can significantly shorten auxiliary time and improve operational smoothness and work efficiency, especially when the jig needs to be opened and closed frequently for loading and unloading. After the rocker arm springs open, the magnetic repulsion helps to keep it in the open state, preventing the rocker arm from falling back due to gravity or accidental contact, interfering with the handling of wires. This provides the operator with a clear operating space and reduces the safety risks caused by accidental contact.

[0021] 4. This invention features a wire clamping plate with multiple wire grooves on the first rocker arm, enabling precise positioning and separation of multiple wire bundles. Each wire groove is adapted to a single wire, effectively preventing adjacent wires from tangling or stacking, ensuring uniform spacing between wires after clamping. This is crucial for precise positioning in subsequent automated processing. By integrating the wire separating function into the clamping rocker arm, there is no need for an additional independent wire separator, resulting in a more compact and concise overall structure. The wire grooves act directly on the clamped wires, achieving positioning and clamping simultaneously, ensuring consistency between wire separating and clamping.

[0022] 5. This invention, through the defined hinge structure and flat end face of the pressure plate, brings significant process convenience. The design of the pressure plate, which can rotate around the Y-axis, provides it with flexible obstacle avoidance capabilities. When it is necessary to operate on the lower layer or adjacent rows of wires held by the first rocker arm, the pressure plate can be flipped upwards so that its flat end face faces outwards. Since this end face is flat, it will not hook or press on adjacent wires, freeing up space for operation.

[0023] 6. This invention optimizes the flipping and limiting structure of the pressure plate. The limiting post precisely controls the flipping angle of the pressure plate, ensuring it stops when its flat end face aligns with the first rocker arm (i.e., in the avoidance state), guaranteeing accurate and reliable positioning. The ball head design at the end of the limiting post is ingenious. When the pressure plate contacts the ball head, the spherical contact adapts to a certain angular deviation, achieving point contact or small-area contact. This not only reduces friction and wear, but more importantly, the ball head provides a small, adaptive clamping force, slightly tightening the pressure plate and eliminating mechanical clearance. This makes it more stable in the avoidance state, less prone to noise or displacement due to vibration, demonstrating the ingenuity of the design. 7. This invention introduces a second magnet. When the wire pressing plate is flipped to face the first rocker arm (i.e., in the non-working state), the attraction force generated by the second magnet can firmly fix the wire pressing plate on the first rocker arm. This ensures that the wire pressing plate will not be accidentally flipped open due to equipment vibration or accidental contact during clamping and subsequent processing, thus preventing interference with the wire. The magnetic attraction provides a soft locking mechanism. The operator only needs to apply a certain force to overcome the magnetic force to flip the wire pressing plate without operating an additional mechanical lock. This ensures stability and simplifies switching operations, taking into account both reliability and convenience.

[0024] 8. This invention extends the clamping object from the wire body to irregularly shaped accessories on the wire by setting a contour block that conforms to the shape of the adhesive block. This contour block design increases the contact area with the adhesive block, evenly distributing the clamping force on the surface of the adhesive block and avoiding localized stress concentration that could cause pressure damage or deformation. The rocker arm function is further subdivided into a first rocker arm for wire splitting and a second rocker arm for pressing the adhesive block, arranged at intervals along the X-axis. This functional division allows different rocker arms to perform their respective tasks, handling different parts of the wire, achieving comprehensive and reliable fixation of the entire wire harness (including the wire body and the adhesive block), creating conditions for subsequent high-precision processing.

[0025] 9. The contour blocks of this invention are detachable and arranged in multiple configurations, giving the fixture excellent adaptability. When producing products with different specifications and shapes of rubber blocks, it is not necessary to replace the entire second rocker arm; only the corresponding contour block needs to be quickly replaced. This greatly reduces changeover costs and time, and improves the flexibility of the production line. Multiple contour blocks can be arranged sequentially along the Y-axis, corresponding to multiple rubber blocks that may exist on the wire, or to different feature parts of a long rubber block. Each contour block can be precisely designed according to the shape of the local rubber block it contacts, thereby achieving multi-point, multi-faceted bonding and clamping of complex rubber blocks, achieving optimal fixation.

[0026] 10. Building upon the existing wire clamping (first rocker arm) and adhesive block fixing (second rocker arm), this invention further incorporates a third rocker arm to clamp and limit the tail end or other free segments of the wire. This adds multiple constraint points along the Y-axis (length direction) of the wire, creating a super-positioning effect that effectively suppresses any minor displacement or vibration that may occur during processing. By comprehensively constraining key points along the entire length of the wire (head wire separation, middle adhesive block, and tail clamping), the stability of the wire's shape and position throughout the entire processing is maximized. This comprehensive fixing is a crucial guarantee for improving the accuracy and consistency of subsequent processes such as cutting, stripping, crimping, and welding, significantly increasing the yield of the final product.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] This invention provides a high-speed wire clamping fixture. Its core innovation lies in the combination of modular functional partitioning and precision mechanical structure, achieving efficient, stable, and multifunctional clamping of wires. The fixture integrates three major functions: wire separation, adhesive block clamping, and wire fixing. Its modular layout solves the problem of comprehensive fixing of complex wire harnesses, adapting to high-speed processing requirements. Through a series of designs including elastic limiting, magnetic assistance (spring-loaded opening and adsorption), flip-out avoidance, and detachable contour blocks, the fixture possesses both high operational convenience and adaptability to various working conditions, enabling rapid changeover and compatibility with multiple wire specifications. By utilizing the combination of magnetic force and mechanical limiting, it ensures clamping rigidity during operation and enables rapid release and avoidance during non-operational states, significantly improving production efficiency and operational reliability.

[0033] Specifically, such as Figures 1-6 As shown, a high-speed wire clamping fixture of the present invention includes a clamping base 1 and multiple sets of rocker arms arranged laterally along the X-direction. The clamping base 1 of the present invention has a U-shaped structure and includes two support arms extending along the X-direction. The two support arms are arranged at intervals along the Y-direction, and the rocker arms are mounted on the two support arms. Each set of rocker arms includes two rocker arms arranged vertically opposite each other along the Z-direction, that is, each set of rocker arms includes two rocker arms placed on both sides of the support arms along the Z-direction. The rocker arms extend longitudinally along the Y-direction, and one end of the rocker arm is rotatably hinged to the clamping base 1 via a pivot, while the other end is a free end. One end of the rocker arm is rotatably hinged to one support arm, and a limiting structure is provided on the other support arm. When the rocker arm is rotated inward to a horizontal state around the pivot, its free end will contact the limiting structure on the other support arm, such as a simple step or a groove, thereby being limited and kept horizontal. At this point, the two rocker arms in the same group are positioned vertically opposite each other, forming a double-sided clamping space for the cable between them. When the two rocker arms in the same group are flipped to a horizontal position, the space between them becomes the clamping space for the cable.

[0034] During operation, first place the cable on the clamping base 1, positioning it between the two rocker arms in the same group. Then, flip both the upper and lower rocker arms inwards until they are locked in a horizontal position by the limiting structure, at which point the cable is clamped. To release the cable, simply release the limiting structure from the rocker arms and flip the rocker arms in the opposite direction.

[0035] In this invention, the rocker arm rotates around a fixed fulcrum, and the trajectory of its free end is predetermined. The limiting structure precisely sets the position of the rocker arm in the horizontal working state. The two rocker arms in the same group simultaneously apply clamping forces to the wire from both above and below, forming a pair of balanced force couples that firmly fix the wire between them.

[0036] The fixture of this invention uses a double-sided clamping method to ensure balanced force on the wire, avoiding bending or displacement that may occur with single-sided clamping, resulting in excellent clamping performance. Simultaneously, the layout of multiple rocker arms allows for the simultaneous processing of multiple parallel wires, improving production efficiency. The rocker arm flipping mechanism combined with the limiting structure provides a simple and intuitive operation with clearly defined states, laying the foundation for high-speed and reliable wire clamping.

[0037] In some embodiments of the present invention, the limiting structure described above has been optimized, specifically, as follows: Figure 1 As shown, this embodiment specifically defines the limiting structure and adds an auxiliary opening structure. Specifically, the limiting structure includes a limiting buckle 9 that is rotatably hinged to the wire clamping base 1 about the X-axis. The limiting buckle 9 is actually a T-shaped block structure. The lower end of the limiting buckle 9 is rotatably hinged to the wire clamping base 1 about the X-axis, and the two ends of the upper end along the Y-axis correspond to the snap-fit ​​end and the press-down end, respectively. When the rocker arm is flipped to the horizontal state, one end of the limiting buckle 9 can be pressed against the free end of the rocker arm. A tension spring (not shown in the figure) is connected between the other end of the limiting buckle 9 and the wire clamping base 1. In addition, at corresponding positions on the wire clamping base 1 and the rocker arm, mutually repelling first magnets (not shown in the figure) are embedded.

[0038] The tension spring is located between the pressing end and the wire clamping base 1. When not pressed, the tension spring applies an upward thrust to the pressing end, and the limiting buckle 9 forms a lever structure. Under the action of the tension spring, the locking end is pressed against the free end of the rocker arm, allowing the rocker arm to clamp the object being held. The free end of the rocker arm is provided with a locking platform protruding in the Y direction, and the locking end of the limiting buckle 9 is provided with a corresponding limiting platform protruding in the Y direction. Under the action of the tension spring, the limiting platform locks against the upper end of the locking platform, applying Z-direction pressure to the limiting buckle 9, forcing the limiting buckle 9 to press against the wire clamping base 1.

[0039] The first magnet is located between the locking end of the limiting buckle 9 and the wire clamping base 1. That is, the first magnet is installed on both the locking end of the limiting buckle 9 and the wire clamping base 1, and the installation position of the first magnet on the wire clamping base 1 corresponds to the first magnet on the rocker arm when it is flipped to the horizontal state. The two overlap in the Z direction. The first magnets of the two are repulsive. When the limiting buckle 9 is released from pressing the free end of the rocker arm, the free end of the rocker arm bounces off the wire clamping base 1 under the repulsive action of the first magnets.

[0040] When clamping the wire, the operator presses the pressing end of the limit latch 9 to open it, flips the rocker arm to a horizontal position, and releases the pressing end. Under the action of the tension spring, the limit latch 9 rotates around the X-axis, and the engaging end of the limit latch 9 presses against the free end of the rocker arm. The tension spring is stretched, providing continuous clamping force. To open, first press the pressing end of the limit latch 9 to release the constraint on the rocker arm. At this time, the repulsive force between the first magnets will immediately push the rocker arm to automatically spring upward, making it convenient for the operator to pick up and put down the wire.

[0041] Under the action of the tension spring, the limit buckle 9 always applies an elastic preload to the end of the rocker arm, which can absorb assembly gaps and achieve a tight clamping without wobbling. The repulsive force of the first magnet acts as an energy storage and auxiliary drive mechanism, releasing energy the instant the constraint is released, causing the rocker arm to open automatically.

[0042] This embodiment utilizes a spring-preloaded snap-fit ​​structure to achieve adaptive clamping of the rocker arm, eliminating gaps that may occur with rigid limiting, resulting in more stable and reliable clamping, especially suitable for high-speed vibration environments. Simultaneously, the magnetic-assisted opening function greatly simplifies operation, improves loading and unloading efficiency, and provides a better user experience.

[0043] In other embodiments of the present invention, this embodiment further subdivides the function of the rocker arm described above, defining a first rocker arm 2 for branching lines. For example... Figures 1-4 As shown, a wire pressing plate 3 is detachably installed on the inner side of the first rocker arm 2 facing the other side of the same group. The wire pressing plate 3 has multiple wire grooves 4 arranged at intervals along the Y direction, and the shape of each wire groove 4 is adapted to the shape of a single wire.

[0044] When dealing with multiple parallel cables, such as ribbon cables, first place the cable bundle in position. Then flip the first rocker arm 2 to the clamping state. At this time, the cable grooves 4 on the pressure plate 3 will clamp each individual cable, separating the cable bundles that might otherwise be clustered together, and applying clamping force to them at the same time.

[0045] This embodiment integrates positioning and clamping functions. The wire groove 4 serves as a guide and divider, ensuring that each wire maintains a predetermined spacing and position after clamping, avoiding tangling or stacking.

[0046] By incorporating a pressure plate 3 with wire grooves 4, this fixture achieves precise wire separation and positioning for ribbon cables. This simple and effective structure ensures consistent wire spacing, creating favorable conditions for subsequent high-precision automated processing.

[0047] In a further embodiment of the present invention, the connection method of the pressure plate 3 is improved. For example... Figure 1 and 3 As shown, the two ends of the pressure plate 3 are hinged to the first rocker arm 2, which can rotate around the Y-axis. At the same time, the side of the pressure plate 3 facing away from the line groove 4 is machined into a flat end face.

[0048] In this embodiment, a through-hole along the Y direction is provided on the first rocker arm 2, such as... Figure 4 As shown, a rotating shaft along the Y direction is installed in the rotating shaft hole, and a through hole along the Y direction is opened on the plate body of the pressure plate 3; one end of the rotating shaft passes through the rotating shaft hole on one side of the first rocker arm 2, and then passes through the through hole on the pressure plate 3, and is inserted into the rotating shaft hole on the other side of the first rocker arm 2, so that the pressure plate 3 can be hinged to the first rocker arm 2 so as to rotate around the Y axis.

[0049] When it is necessary to operate on the next layer or adjacent row of cables held by the first rocker arm 2, the operator can manually flip the pressure plate 3 upwards or outwards so that its flat end faces the cable side, while the side with the cable groove 4 is retracted. When it is necessary to restore the cable splitting function, simply flip the pressure plate 3 back to its original position.

[0050] The hinged structure allows the wire clamping plate 3 to have two working states: one is the wire clamping state with the wire groove 4 facing the wire; the other is the clearance state with the flat end face facing the wire. The flat end face is smooth and has no protrusions, so it will not interfere with the surrounding wires.

[0051] The flip-up design of the pressure plate 3 provides great operational flexibility. When working with multiple layers of cables, the upper pressure plate can be easily flipped up to avoid interfering with the operation of the lower layers of cables, allowing the fixture to adapt to more complex wire harness structures and multi-layer wiring processes.

[0052] In a preferred embodiment of the present invention, this embodiment adds a structure to limit the flipping angle of the pressure plate 3. For example... Figure 4As shown, a limiting post 5 is provided on the first rocker arm 2, corresponding to the position where the pressure plate 3 is flipped to its flat end face and fits against the first rocker arm 2. The end of the limiting post 5 facing the pressure plate 3 has a smooth ball head. The first rocker arm 2 has a U-shaped groove for assembling the pressure plate 3, and the limiting post 5 is located on both sides of this U-shaped groove, corresponding to the Y-direction sides of the pressure plate 3. The limiting post 5 is arranged along the Y-direction, located within the U-shaped groove of the first rocker arm 2, and its end extending out of the groove has a smooth ball head structure.

[0053] When the operator flips the pressure plate 3 to the avoidance position, the side of the pressure plate 3 will gradually approach the limit post 5. When the flat end face of the pressure plate 3 is about to fit against the first rocker arm 2, its side edge will first contact the ball head of the limit post 5 and be held in place by the ball head, thus stopping precisely at the preset avoidance position.

[0054] The limiting post 5 serves as a mechanical limiter, preventing the pressure plate 3 from over-rotating. The ball head design at its end ensures point contact with the pressure plate 3, which can accurately position the plate, reduce friction, and eliminate wobbling caused by processing errors through slight elastic deformation or clamping force, keeping the pressure plate 3 stable in the avoidance state.

[0055] The limiting post 5 and its ball head design provide precise positioning and reliable holding for the pressure plate 3 in its avoidance state. This not only ensures the accuracy of the avoidance position, but also eliminates gaps through the adaptive contact of the ball head, allowing the pressure plate 3 to remain stable even when not in operation, avoiding the risk of noise caused by vibration or accidental fall.

[0056] In other embodiments of the invention, a state-maintaining structure is introduced. A second magnet is embedded between the first rocker arm 2 and the pressure plate 3, attracting each other. When the pressure plate 3 is flipped so that the side of the wire groove 4 faces the first rocker arm 2, the attraction of the second magnet is sufficient to attract and fix the pressure plate 3 onto the first rocker arm 2.

[0057] When the operator flips the pressure plate 3 from the avoidance position back to the working position, as the pressure plate 3 approaches the first rocker arm 2 to a certain distance, the attraction of the second magnet will activate, automatically snapping the pressure plate 3 into place on the first rocker arm 2, thus bringing it into a stable working state. To flip it again, simply apply an external force greater than the magnetic attraction.

[0058] Magnetic force provides a non-permanent, surmountable holding force. When a state needs to be maintained, the magnetic force provides sufficient constraint; when a state needs to be switched, it can be easily overcome by human effort.

[0059] The second magnet cleverly solves the problem that the wire clamping plate 3 might flip up on its own due to accidental contact during operation. It provides a reliable soft lock in a simple and wear-free manner, ensuring the continued effectiveness of the wire clamping function without affecting the convenience of manual switching.

[0060] In some embodiments of the invention, this embodiment introduces a rocker arm type for handling adhesive patches on wires. For example... Figure 1 , 2 As shown in Figure 5, the rocker arm further includes a second rocker arm 6. The second rocker arm 6 is arranged at a distance from the aforementioned first rocker arm 2 along the X direction, and is generally located behind the first rocker arm 2 in the X direction. On the inner side of the second rocker arm 6 facing the other side of the same group of second rocker arms, a contour block 7 that conforms to the shape of the rubber block to be clamped is provided. Preferably, there are multiple contour blocks 7, which are detachably mounted sequentially on the second rocker arm 6 along the Y direction.

[0061] When handling wires with adhesive blocks, after placing the wires, the adhesive blocks should be positioned precisely between the upper and lower second rocker arms 6. Flipping the second rocker arms 6 to the clamping position will cause the upper and lower contour blocks 7 to adhere to the surface of the adhesive block from both sides, securing it firmly. If the specifications of the adhesive block change, simply remove the original contour block 7 and replace it with a contour block that matches the new adhesive block.

[0062] The contour block 7 increases the contact area with the irregularly shaped rubber block, distributing the clamping force of the wire harness across the entire surface of the rubber block and avoiding localized stress. The detachable design allows the fixture to be adapted to different product models by replacing components.

[0063] This embodiment provides a specialized solution for special structural adhesive blocks on wires. The contour block 7 can perfectly fit the adhesive block, achieving non-destructive and stable clamping. The design of multiple detachable contour blocks allows the fixture to easily handle different or multiple adhesive blocks distributed along the Y-direction, greatly improving the fixture's versatility and flexibility, and reducing production changeover costs.

[0064] In other embodiments of the present invention, a third rocker arm 8 is further added to the existing first rocker arm 2 and second rocker arm 6. For example... Figure 1 , 2 As shown in Figure 6, the third rocker arm 8 is arranged at intervals with the second rocker arm 6 along the X direction, and is located on the rear side of the second rocker arm 6 in the X direction. Its basic structure is similar to that of the first rocker arm 2, and it is mainly used for ordinary clamping and limiting of the tail or middle free section of the wire.

[0065] In this embodiment, elongated holes are provided on both sides of the wire clamping base 1, which pass through the wire clamping base 1 in the X direction. A rotating shaft arranged in the X direction is inserted in the elongated hole. The rotating shaft passes through the shaft holes on the first rocker arm 2, the second rocker arm 6 and the third rocker arm 8 in sequence, so that the first rocker arm 2, the second rocker arm 6 and the third rocker arm 8 can be hinged to the wire clamping base 1 so as to rotate around the X-axis.

[0066] When placing a long cable, guide it sequentially through the first rocker arm 2 corresponding to the cable end or branch point, the second rocker arm 6 corresponding to the adhesive block, and the third rocker arm 8 corresponding to the tail end. Rotate each set of rocker arms in sequence to achieve comprehensive, multi-point fixation of the cable from front to back.

[0067] By adding more constraint points to the third rocker arm along the Y-axis of the wire length, the vibration or displacement that may occur in the suspended part of the wire under high-speed movement can be effectively suppressed, thereby improving the dynamic stability of the entire system.

[0068] The third rocker arm 8 extends wire fixation from a single point to the entire wire. Working in conjunction with the first and second rocker arms, it provides multi-point support at key locations on the wire—the head, the adhesive block, and the tail—effectively minimizing any slight displacement of the wire during processing. This comprehensive fixation is crucial for ensuring consistent and stable quality in subsequent high-precision, high-speed processing steps such as cutting, stripping, and crimping.

[0069] In practical applications, this invention also involves a set of preferred, highly integrated high-speed wire clamp fixture detailed structural schemes.

[0070] At the core of this fixture is a stable wire clamping base 1. Along the X direction, multiple functional groups are arranged at intervals, each group including a pair of rocker arms facing each other vertically. These rocker arms are subdivided into a first rocker arm 2, a second rocker arm 6, and a third rocker arm 8 according to their functions.

[0071] Clamping and opening mechanism: One end of each rocker arm is hinged to the wire clamping base 1 via a pivot. When the rocker arm is flipped to the horizontal working position, a limit latch 9 with a tension spring elastically presses its end to ensure a secure clamping without wobbling. At the same time, a first magnet that repels each other is embedded between the wire clamping base 1 and the rocker arm. When the limit latch 9 is opened, the magnetic force assists the rocker arm to automatically spring up, facilitating operation.

[0072] Splitting and Clamping Functions: The first rocker arm 2 is used for splitting and clamping the ends of the wire harness. A wire clamping plate 3 is hinged to it, and the plate has multiple grooves 4 adapted to individual wires. In operation, a second magnet attracts the wire clamping plate 3 to the first rocker arm 2, and the grooves 4 precisely separate and clamp the wires. When it is necessary to operate on the lower layer of wires, the wire clamping plate 3 can be flipped outwards, with its flat end facing the wire. Simultaneously, the ball-headed limiting post 5 on the first rocker arm 2 will precisely fix it in a clearance position.

[0073] Irregular part clamping function: The second rocker arm 6 is located behind the first rocker arm 2 and is used to clamp the rubber block on the wire. Multiple contour blocks 7 arranged along the Y direction are detachably mounted on it. The shape of the contour blocks 7 is completely fitted to the rubber block to be clamped, which can securely and firmly fix the rubber block.

[0074] Auxiliary fixing function: The third rocker arm 8 is located behind the second rocker arm 6 and is used to assist in pressing the tail or other free sections of the wire, increasing the constraint points of the wire along the Y direction, and preventing it from shaking or shifting during high-speed processing.

[0075] In summary, the fixture of this invention integrates multiple advanced functions, including balanced clamping on both sides, elastic self-locking, magnetically assisted opening and closing, precise wire separation, contour clamping of irregularly shaped parts, multi-layer avoidance, and multi-point stable fixation. The components work together to form a high-performance wire harness processing fixture that is easy to operate, reliable in clamping, widely adaptable, and capable of meeting the demands of high-speed and high-precision processing. This solution, through its ingenious mechanical structure design, effectively solves many problems existing in the prior art, significantly improving production efficiency and product yield.

Figure 2 The left and right directions in the middle; the Z direction of this invention is Figure 3 The up and down directions in the middle.
