Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing technology, and in particular to a wire harness terminal crimping device for automotive parts manufacturing. Background Technology

[0002] In the wire harness manufacturing process, the crimping quality of terminals and cables directly affects the reliability and safety of the electrical connection. Traditional crimping devices often employ simple mechanical stamping methods, where operators manually place the terminals and cables and then drive the upper die to press down to complete the crimping. This method has significant drawbacks:

[0003] First, the crimping force usually depends on the equipment preset or the operator's experience, which cannot be monitored and controlled in real time, easily leading to quality problems such as insufficient crimping force (poor connection) or excessive crimping force (damaging the cable);

[0004] Secondly, the lack of effective crimping completion indicators makes it difficult for operators to intuitively judge whether each crimping is qualified, requiring reliance on subsequent inspections, which reduces production efficiency and increases quality risks.

[0005] Furthermore, the positioning of terminals and cables in existing devices often relies on simple clamps, which are prone to displacement during the crimping process, affecting the crimping accuracy.

[0006] Therefore, there is an urgent need for a wire harness terminal crimping device that can monitor the crimping force in real time during the crimping process, provide clear completion prompts, and ensure crimping alignment accuracy. Summary of the Invention

[0007] The present invention aims to overcome the shortcomings of the prior art and provide a wire harness terminal crimping device for automotive parts production, which can monitor the crimping force in real time and give a clear prompt when the specified pressure is reached, effectively ensuring the consistency and reliability of crimping quality.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A wire harness terminal crimping device for automotive parts manufacturing includes a base plate, a support mechanism, a first support plate, a first connecting plate, a pressing rod, a second connecting plate, a first clamping mechanism, a second clamping mechanism, and a pressure monitoring mechanism.

[0010] The support mechanism is disposed above the base plate to provide vertical elastic buffering and reset support. The first support plate is vertically fixed to one side of the base plate. The first connecting plate is fixed to the top of the first support plate. The pressing rod is movably disposed in the central hole of the first connecting plate and extends downward. The second connecting plate is suspended directly below the pressing rod and coaxially connected to the pressing rod. The first clamping mechanism is disposed on the bottom surface of the second connecting plate to clamp and position the wire harness terminals. The second clamping mechanism is disposed above the base plate and directly below the second connecting plate to fix the wire harness to be crimped. The pressure monitoring mechanism is disposed on the base plate and surrounds the second clamping mechanism.

[0011] The working process is as follows: After placing the terminal in the first clamping mechanism and the cable in the second clamping mechanism, the pressing rod is driven downwards, causing the second connecting plate and the first clamping mechanism to press down as a whole. During this process, the support mechanism provides cushioning. When the terminal on the first clamping mechanism contacts the cable on the second clamping mechanism and begins to crimp, the pressure continuously increases. When the pressure is transmitted to the pressure monitoring mechanism and reaches a preset threshold, the pressure monitoring mechanism emits audible and visual warning signals, indicating that the crimping force has reached the standard and the crimping is complete. Subsequently, the pressing rod rises, and the support mechanism pushes the second connecting plate to reset.

[0012] Furthermore, the support mechanism includes at least three telescopic columns arranged in a circumferential array, a first housing sleeved outside the telescopic columns, a first slider located at the top of the telescopic columns and slidably connected to the bottom surface of the second connecting plate, a spring column disposed within the first housing to provide a reset elastic force, and a second support plate for limiting the stroke of the telescopic columns. This structure ensures the smoothness of the pressing process and the automatic reset function.

[0013] Furthermore, the first clamping mechanism includes a first connecting block connected to the second connecting plate, a third connecting plate disposed below it, a first drive motor fixed to one side of the third connecting plate, a threaded rod driven by the motor, a first sliding rod arranged in parallel, a first clamping block that cooperates with the threaded rod and the first sliding rod and can move horizontally, and a pressure block disposed at the bottom of the first clamping block. The horizontal position of the pressure block can be precisely adjusted by the first drive motor to accommodate terminals of different specifications.

[0014] Furthermore, the second clamping mechanism includes a second connecting block fixed to the base plate, a clamping plate disposed above it, a second drive motor fixed to one side of the clamping plate, a threaded post driven by the motor, a parallel second slide bar, a second clamping block that cooperates with the threaded post and the second slide bar and can move horizontally, a third connecting block disposed above the second clamping block, and a placement slot formed on the top surface of the third connecting block for placing cables. The second clamping block can be moved by the second drive motor, thereby securely clamping the cables.

[0015] Furthermore, the pressure monitoring mechanism is its core component, comprising a support column vertically fixed to the base plate, a second housing sleeved over the support column, a cover plate fitting over the top of the second housing, bolts for adjusting the pressure threshold, a second slider that can slide along the support column, a conductive slot on the side wall of the second slider, and a battery and indicator light assembly housed within the second housing. When the second connecting plate presses down, causing the second slider to move downwards to the set pressure point, the conductive slot deforms and conducts the circuit, triggering the indicator light assembly to illuminate, thus providing a pressure threshold indication.

[0016] Furthermore, the indicator light assembly includes a first ring light surrounding the battery and a second ring light surrounding the first ring light, which can indicate different states through different colors or flashing patterns.

[0017] Furthermore, the top of the support column is a conical head, and the second slider has a matching conical inner cavity to achieve self-centering guidance, ensure uniform force distribution, and accurate monitoring.

[0018] Furthermore, the conductive slot is made of an elastic conductive material (such as an elastic copper sheet) to ensure reliable contact and conduction under pressure.

[0019] Furthermore, the first clamping block and the pressure block are detachably connected, which facilitates the replacement of different shaped crimp connectors to accommodate various terminal models.

[0020] Furthermore, the bottom of the placement slot is provided with anti-slip texture to increase the stability of the cable when it is placed.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. Real-time pressure monitoring and intuitive prompts: By setting up an independent pressure monitoring mechanism, the pressure changes during the crimping process can be sensed in real time. When the pressure reaches the pre-set qualified threshold, the operator will be immediately notified by lights or other signals. This effectively avoids under-pressure or over-pressure, ensures the consistency of quality at every crimping point, reduces the need for subsequent full inspection, and improves production efficiency and product qualification rate.

[0023] 2. Dual Buffering and Precise Positioning: The combination of spring columns and telescopic columns in the support mechanism provides effective buffering for the downward pressing action from above, protecting the terminals and cables; at the same time, both the first and second clamping mechanisms adopt the clamping method of motor-driven lead screws, realizing precise and stable positioning of terminals and cables in the horizontal direction. Combined with the conical guide structure of the pressure monitoring mechanism, it ensures the accuracy of crimping alignment.

[0024] 3. Compact structure and good adaptability: The device integrates crimping, clamping, buffering, and monitoring functions into one unit with a reasonable layout. The detachable pressure block and adjustable clamping position enable the device to adapt to crimping operations of wire harness terminals of different models and specifications, making it highly versatile.

[0032] 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.

[0033] Such as Figures 1 to 6As shown, the present invention provides a wire harness terminal crimping device for automotive parts production, comprising a horizontal base plate 1 as the foundation of the entire device. A first support plate 2 is vertically fixed to one side of the base plate 1, and a first connecting plate 3 is fixed to its top. A crimping rod 4 passes through a hole in the center of the first connecting plate 3 and can be driven up and down by an external driving mechanism (such as a hydraulic cylinder or an electric push rod, not shown in the figure).

[0034] A second connecting plate 5 is coaxially connected to the lower end of the extrusion rod 4. A support mechanism 7 is provided between the second connecting plate 5 and the base plate 1. Specifically, as shown... Figure 3 As shown, the support mechanism 7 includes three or more (e.g., four) telescopic columns 71 evenly distributed along the circumference of the base plate 1. Each telescopic column 71 is encased in a first housing 72, with a first slider 73 at its top that slides in contact with the bottom surface of the second connecting plate 5. A spring column 74 is located inside the first housing 72, and a second support plate 75 for limiting its position is located at its bottom. In its natural state, the spring force of the spring column 74 supports the second connecting plate 5 at a high position via the first slider 73. When the pressing rod 4 is pressed down, the second connecting plate 5 overcomes the spring force and descends, thus the entire support mechanism 7 provides cushioning and guidance.

[0035] like Figure 2 As shown, the first clamping mechanism 6 is mounted on the bottom surface of the second connecting plate 5. It includes a first connecting block 61 fixed to the second connecting plate 5 and a third connecting plate 62 connected below. A first drive motor 63 is mounted on one side of the third connecting plate 62, and a threaded rod 64 connected to its output shaft and a parallel first slide rod 65 pass through a first clamping block 66. A pressure block 67 for crimping is mounted on the bottom of the first clamping block 66. Activating the first drive motor 63 can drive the first clamping block 66 to move horizontally, thereby adjusting the position of the pressure block 67 to clamp terminals of different widths.

[0036] like Figure 4 As shown, the second clamping mechanism 8 is fixed to the base plate 1, located directly below the first clamping mechanism 6. It includes a second connecting block 81 fixed to the base plate 1, on which a clamping plate 82 is mounted. A second drive motor 83 is mounted on one side of the clamping plate 82, and its driven threaded post 84 and parallel second slide bar 85 pass through a second clamping block 86. A third connecting block 87 is fixed above the second clamping block 86, and its top surface has a placement slot 88 for placing cables. Activating the second drive motor 83 drives the second clamping block 86 to move, thereby clamping or releasing the cables placed in the placement slot 88.

[0037] The key improvement of this invention lies in the inclusion of a pressure monitoring mechanism 9. For example... Figure 5 and Figure 6As shown, the mechanism comprises multiple (typically three, arranged in a triangle for stability) units mounted on the base plate 1 and surrounding the second clamping mechanism 8. Each unit includes a support column 91 vertically fixed to the base plate 1, the support column 91 being fitted with a second housing 92, and the top being closed by a cover plate 93. A bolt 94 passes through the cover plate 93 and is threadedly connected to the second housing 92; rotating the bolt 94 adjusts its extension length inside. A slidable second slider 95 is fitted onto the support column 91, and its sidewall has a conductive groove 96. A battery 97 is mounted at the bottom of the second housing 92, and a first ring light 98 and a second ring light 99 are sequentially fitted around the battery 97. The top of the support column 91 is preferably conical, and the second slider 95 has a matching conical inner cavity to ensure alignment. The conductive groove 96 is made of a flexible copper sheet.

[0038] Working Principle: Before crimping, the terminal is placed under the pressure block 67 of the first clamping mechanism 6, and the stripped cable is placed in the placement slot 88 of the second clamping mechanism 8. Two drive motors (63, 83) are then driven to clamp the cable. The external drive is activated, and the pressing rod 4 presses down, causing the second connecting plate 5, the first clamping mechanism 6, and the support mechanism 7 to descend as a whole. After the terminal contacts the cable, crimping begins. The pressure is transmitted through the second connecting plate 5 to the second slider 95 of the pressure monitoring mechanism 9 below. When the crimping force reaches the preset value (this value is preset via the adjusting bolt 94), the second slider 95 moves down, causing the conductive slot 96 to elastically deform, contacting the conductive circuit. The battery 97 powers the first ring light 98 and / or the second ring light 99, emitting light (e.g., a green light), clearly indicating to the operator that the crimping force has passed. After crimping is completed, the pressing rod 4 rises back, and under the action of the spring column 74 of the support mechanism 7, the entire upper mold part resets, ready for the next operation.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
