Description

Technical Field

[0001] This invention relates to the field of auxiliary welding technology, and in particular to an electronic connector positioning welding device. Background Technology

[0002] Electronic connectors are core components in modern electronic devices, enabling electrical connections and signal transmission between modules. Their soldering quality directly determines the reliability and long-term stability of the circuit connection. As electronic products become increasingly miniaturized and highly integrated, the pin spacing of electronic connectors is shrinking while their number is increasing, posing unprecedented challenges to the precision and consistency of the soldering process. Currently, in automated production lines, industrial robots equipped with specialized gripping tools are commonly used to pick up, transport, position, and align electronic connectors with circuit boards, followed by soldering through reflow soldering or selective soldering. Despite the widespread use of automated equipment, the technical level of the positioning and soldering device, as a critical execution end, directly restricts the final soldering yield and production efficiency. Currently, several technical problems remain to be solved in common positioning and soldering devices or methods in this field:

[0003] Significant deficiencies exist in positioning accuracy and soldering process stability. Existing devices are typically designed to reliably grip the connector's plastic body, with positioning references largely based on the shell contour. However, what actually needs precise alignment with the solder pads and metallurgical bonding are the slender and flexible metal leads. Due to the lack of independent, direct physical constraints and limiting mechanisms for the leads themselves, they are highly susceptible to micron-level offsets or elastic deformations caused by inertial forces, thermal stress, or equipment vibrations during device movement or soldering heating. These minute variations are sufficient to cause misalignment between the lead tip and the PCB solder pad, leading to fatal defects such as post-soldering bridging, cold solder joints, or inaccurate positioning. Furthermore, common clamping drive mechanisms may experience impacts or vibrations when providing clamping force, further compromising the static stability of the positioning state.

[0004] The equipment suffers from a severe lack of versatility and production line flexibility. Electronic equipment manufacturing operates on a multi-variety, variable-batch production model, with a single production line often handling various models and specifications of electronic connectors. These connectors differ in external dimensions, pin count, pin arrangement, pin spacing, and pin height. Most existing positioning and soldering tools are specialized fixtures with fixed clamping cavity dimensions and rigid limiting structures. When product types change, time-consuming manual replacement, reinstallation, and accuracy verification are required, severely impacting production efficiency and overall equipment utilization. The few adjustable fixtures available have limited adjustment dimensions, are cumbersome to operate, and struggle to ensure uniform and reliable pin positioning after adjustment.

[0005] The existing devices are functionally limited and lack the ability to monitor and physically protect the process. Essentially, they are passive mechanical execution units, capable only of basic "grab-place" actions. They cannot proactively detect and warn of potential defects in the incoming connectors, such as missing or bent pins, before the irreversible soldering process begins. Soldering defective workpieces will lead to subsequent system testing failures and rework, resulting in high costs. Furthermore, the high temperatures generated during soldering are conducted through the pins. If these heats accumulate locally and cannot dissipate quickly, they may exceed the heat resistance limit of the connector's plastic body, causing melting, deformation, or performance degradation. This can also affect the pin plating and the microstructure of the solder joints. Existing devices typically do not integrate any active or passive heat dissipation structures to mitigate this problem.

[0006] The integration of automation and intelligence is insufficient, and the human-machine interaction is unfriendly. To achieve highly reliable and precise alignment, many existing production lines still require operators to observe through microscopic vision systems and manually remotely adjust the position of the devices, which has become a bottleneck to achieving fully unmanned automated production. The entire system struggles to form a closed loop of "perception-decision-execution." Furthermore, under high-speed automated cycles, the rapid movement of robotic arms and grippers can cause rigid collisions between connectors and devices. Existing rigid grippers and limit blocks lack cushioning designs, easily leaving indentations and scratches on the connector surface, and even causing internal structural cracks, resulting in potential damage that is difficult to detect.

[0007] Existing technical solutions also have shortcomings in terms of system integration and ease of maintenance. To achieve different functions such as clamping and adjustment, multiple independent drive sources and complex transmission mechanisms are often required, resulting in bulky and heavy devices that are not suitable for lightweight robotic arms that are sensitive to end-effector loads. This also increases manufacturing costs and failure rates.

[0008] The present invention aims to solve the technical problems existing in the prior art. To this end, an electronic connector positioning and welding device is proposed. Summary of the Invention

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. Achieve high-precision, high-quality positioning and welding.

[0027] The device works in concert with two independent adjustment mechanisms and an external robotic arm to perform multi-dimensional, high-precision positioning of the electronic connector body and its pins, ensuring accurate soldering.

[0028] The unique fine-tuning pin limiting mechanism can directly abut against and restrict the movement of the pins during soldering, effectively preventing pin displacement or deformation caused by soldering heat or external force, thus fundamentally ensuring the accuracy of soldering.

[0029] The structure, including the support guide column, return spring, positioning slide, and slider, ensures smooth movement during clamping and adjustment, providing a stable working environment for welding.

[0030] 2. Possesses excellent adaptability and flexibility

[0031] The adjustable clamping and fixing mechanism can flexibly adjust the spacing of the movable mounting plate through the adjustable telescopic column, and with the staggered limit stop bar, it can reliably clamp and fix electronic connectors of different sizes, and has strong versatility.

[0032] The swing mounting plate can change its angle through the angle adjustment shaft, which makes it easier to "capture" and accommodate connectors, improving the fault tolerance and efficiency of the robotic arm operation.

[0033] The fine-tuning pin limiting mechanism has three-dimensional adjustment capability, and the spacing of the limiting modules is adjustable, which can accurately adapt to pins with different arrangements and heights.

[0034] 3. Integrated intelligent detection and thermal management functions

[0035] The guide mounting post, the conductive variable-diameter limiting post, and the conductive layer inside the guide mounting hole form an ingenious electrical contact detection circuit. Based on whether there is continuity and the location of the continuity, it is possible to indirectly determine whether the pin is present or whether it has been bent or deformed, thus achieving rapid quality pre-inspection before soldering.

[0036] The aforementioned conductive structure can dissipate heat from the pins in a timely manner during soldering, thus playing a role in heat dissipation, preventing damage to the electronic connector due to localized overheating, and improving the safety of the soldering process.

[0037] 4. Improve automation efficiency and user-friendliness

[0038] The fixed mounting frame is designed to connect with a robotic arm. The clamping and positioning processes can be electrically or pneumatically controlled by driving the winding drum, fine-tuning telescopic column, and displacement drive components, making it easy to integrate into automated production lines.

[0039] The device automatically completes a series of actions such as clamping, fine-tuning positioning, and pin limiting, reducing the reliance on manual fine-tuning in traditional welding and improving production cycle time and consistency.

[0040] After welding is completed, the electromagnetic plate is energized and can attract and reset the guide mounting column, preparing it for the next operation, making the process seamless.

[0041] 5. Provides effective workpiece protection

[0042] The curved guide spring plate on the swing mounting plate provides flexible contact during the initial clamping stage, avoiding physical damage to the precision electronic connector caused by rigid impact.

[0043] The return spring provides a constant and flexible clamping force for the clamping action, ensuring reliable fixation while preventing damage to the workpiece. Attached Figure Description

Detailed Implementation

[0061] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0062] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0063] Example 1, please refer to Figures 1-4 In this embodiment of the invention, an electronic connector positioning and welding device includes a fixed mounting frame 1 horizontally positioned at the top center. Several bent mounting plates 3 are evenly spaced on the upper sides of both ends of the fixed mounting frame 1, each with a through mounting hole 4. Welding mounting plates 2 are positioned on the lower sides of both ends of the fixed mounting frame 1, each with an evenly spaced mounting hole 4. Fixed mounting plates 7 are positioned opposite each other on the lower left and right sides of the fixed mounting frame 1. Two fixed mounting brackets 5 are respectively positioned at the left and right ends of the fixed mounting frame 1, and are respectively fixed to the two fixed mounting plates 7. A reinforcing frame 6 connects the two fixed mounting brackets 5 at the same end. Two sliding mounting posts 22 are symmetrically positioned horizontally on the lower front and rear sides of the fixed mounting frame 1. Limiting mounting plates 20 are symmetrically positioned at both ends of the sliding mounting posts 22, and each limiting mounting plate 20 is connected to the opposite fixed mounting plate 7 via a supporting guide post 8. The device also includes two sets of adjustable clamping and fixing mechanisms and a fine-tuning pin limiting mechanism.

[0064] The mounting frame 1 is installed by bending the mounting plate 3 and fixing the mounting holes 4 on it, so that the mounting frame 1 is fixed on the externally set robotic arm. Then, the external welding equipment is fixedly installed by welding the mounting plate 2 and fixing the mounting holes 4 on it. As the robotic arm moves the device above the electronic connector welding station, the electronic connector is clamped and fixed in the welding position by two sets of adjustable clamping and fixing mechanisms, which can adapt to the clamping and fixing requirements of electronic connectors of different sizes. Then, the position of the pins on the electronic connector is limited by the fine-tuning pin limiting mechanism, so that the pins are positioned and welded, ensuring that the pin position is fixed during the welding process, and is not easily deformed by force and temperature, thus ensuring the accuracy of electronic connector welding.

[0065] Example 2, based on Example 1, please refer to... Figures 4-8 In this embodiment of the invention, the adjustable clamping and fixing mechanism includes a synchronously movable mounting plate 9 horizontally arranged below the supporting guide column 8. The upper end of the synchronously movable mounting plate 9 is provided with a supporting guide cylinder 10 in conjunction with the supporting guide column 8. A push ring 25 is provided on the side of the supporting guide cylinder 10 facing the fixed mounting plate 7. A reset spring 13 is sleeved on the supporting guide column 8 between the push ring 25 and the fixed mounting plate 7. A power supply guide groove 23 is horizontally arranged on the lower side of the supporting guide column 8. A power supply guide block 28 is provided on the inner wall of the supporting guide cylinder 10 in conjunction with the power supply guide groove 23. A drive winding cylinder 14 is arranged in the middle position of the fixed mounting plate 7. A wire cylinder 18 extends out from the lower end of the drive winding cylinder 14. A traction rope 19 extends out from the drive winding cylinder 14 through the wire cylinder 18. The outer end of the traction rope 19 is connected to the synchronously movable mounting plate 9.

[0066] The lower side of the synchronous moving mounting plate 9 is symmetrically provided with positioning mounting plates 15, and movable mounting plates 16 are symmetrically provided between the positioning mounting plates 15. The side of the positioning mounting plates 15 facing the movable mounting plates 16 is connected to the movable mounting plates 16 through adjustable telescopic columns 26. One end of the movable mounting plates 16 is provided with several limiting baffles 27 at equal intervals. The limiting baffles 27 on the symmetrical movable mounting plates 16 are staggered. The other end of the movable mounting plates 16 is provided with a swing mounting plate 17 through an angle adjustment shaft 29. One side of the swing mounting plate 17 is provided with several arc-shaped guide spring plates 31 at equal intervals.

[0067] Based on the current size of the electronic connector being welded, the spacing between the movable mounting plates 16 is controlled by the adjustable telescopic column 26. While the movable mounting plates 16 are adjusted, the misaligned limit stop strips 27 are simultaneously displaced to restrict the movement of the electronic connector.

[0068] By driving the winding drum 14 to retract and release the traction rope 19, the synchronous moving mounting plate 9 can be stably moved under the guidance and sliding cooperation of the support guide drum 10 and the support guide column 8. At the same time, the return spring 13 provides a stable clamping force for clamping. Specifically, when the device is in the welding position, the driving winding drum 14 releases the traction rope 19, and the push ring 25 is pushed under the action of the return spring 13, so that the support guide drum 10 and the synchronous moving mounting plate 9, together with the movable mounting plate 16 and the limiting stop bar 27 on it, move towards the electronic connector until the movable mounting plate 16 and the limiting stop bar 27 at both ends clamp and fix the electronic connector. At this time, the horizontal position of the electronic connector can be changed by driving the winding drum 14 at both ends to retract and release the traction rope 19. Based on the operation of the external robotic arm, high-precision position adjustment can be performed.

[0069] The angle of the swing mounting plate 17 is controlled by the angle adjustment shaft 29, which improves the capture rate of the electronic connector, reduces the adjustment steps of the external robotic arm, and improves efficiency. At the same time, the arc-shaped guide spring plate 31 on the swing mounting plate 17 can buffer the electronic connector and avoid damage caused by rigid impact.

[0070] Example 3, based on Example 2, please refer to... Figures 9-15 In this embodiment of the invention, the fine-tuning pin limiting mechanism includes a sliding mounting cylinder 11 sleeved outside the sliding mounting column 22. A rotating U-shaped frame 34 is mounted on the lower end of the sliding mounting cylinder 11 via a driving rotating column 33. A limiting module is mounted on the outer end of the rotating U-shaped frame 34. The limiting module includes a deflection mounting plate 12. A plurality of positioning grooves 24 are provided at equal angles on the outer side of the sliding mounting column 22. Positioning sliders 32 are provided on the inner wall of the sliding mounting cylinder 11 to fit the positioning grooves 24. Fine-tuning telescopic columns 21 are provided on the limiting mounting plate 20 directly opposite the sliding mounting cylinder 11. The ends of the fine-tuning telescopic columns 21 are connected to the ends of the sliding mounting cylinder 11. The rotating U-shaped frame... A deflection drive shaft 35 is symmetrically arranged at the outer end of the 34. A deflection mounting cover 36 is provided at the opposite end of each deflection drive shaft 35. A deflection mounting plate 12 is arranged between the deflection mounting covers 36. A guide mounting groove 43 is provided on the side of each deflection mounting cover 36 facing the deflection mounting plate 12. A guide mounting block 41 is provided at both ends of the deflection mounting plate 12 in conjunction with the guide mounting groove 43. A guide displacement stud 42 is vertically arranged inside the deflection mounting cover 36. A guide displacement screw hole 48 is provided through the guide mounting block 41 in conjunction with the guide displacement stud 42. A displacement drive component 37 is provided at the end of the deflection mounting cover 36 in conjunction with the guide displacement stud 42. The displacement drive component 37 can be a motor.

[0071] Once the electronic connector is clamped and fixed, the angle of the rotating U-shaped frame 34 is adjusted by driving the rotating column 33, changing the position and height of the deflection mounting plate 12. The angle of the deflection mounting cover 36 and the deflection mounting plate 12 on it is adjusted by the deflection drive shaft 35. Then, the guide displacement stud 42 is rotated by the displacement drive component 37, which, in conjunction with the guide displacement screw hole 48, causes the guide mounting block 41 to be displaced and adjusted within the guide mounting groove 43, thereby achieving the adjustment of the distance between the deflection mounting plate 12 and the pins on the electronic connector. On this basis, the sliding mounting cylinder 11 is moved and displaced on the sliding mounting column 22 by the fine-tuning telescopic column 21. At this time, the positioning slide groove 24 and the positioning slider 32 cooperate to make the fine-tuning and displacement process of the sliding mounting cylinder 11 on the sliding mounting column 22 smooth.

[0072] The limiting module includes an electromagnetic plate 39 arranged parallel above the deflection mounting plate 12. The two ends of the electromagnetic plate 39 are fixed to the deflection mounting plate 12 by mounting posts. The interior of the deflection mounting plate 12 has a plurality of variable diameter mounting holes 44 arranged vertically at equal intervals. The upper end of the variable diameter mounting holes 44 extends out of the deflection mounting plate 12 and faces the electromagnetic plate 39. The lower end of the variable diameter mounting holes 44 passes through the deflection mounting plate 12 through guide mounting holes 45. A guide mounting post 46 is arranged in conjunction with the guide mounting hole 45. A variable diameter limiting post 40 is arranged at the upper end of the guide mounting post 46 in conjunction with the variable diameter mounting hole 44. An electromagnetic induction suction cup 47 is arranged at the upper end of the variable diameter limiting post 40 in conjunction with the electromagnetic plate 39. A conductive layer is arranged inside the guide mounting hole 45. The guide mounting post 46 and the variable diameter limiting post 40 are made of conductive material. The middle part of the guide mounting post 46 is an enameled layer 30. Reinforcing spokes 38 are arranged horizontally on both the front and rear sides of the deflection mounting plate 12.

[0073] When the deflection mounting plate 12 moves to the target position and is at a certain angle, the electromagnetic plate 39 is de-energized. Under the action of gravity, the guide mounting post 46 slides past the variable diameter mounting hole 44 and slides out of the deflection mounting plate 12 in conjunction with the guide mounting hole 45, and abuts against the pin area of ​​the electronic connector. When the guide mounting post 46 directly abuts against the pin, the variable diameter limiting post 40 is in clearance fit with the variable diameter mounting hole 44 and cannot contact the inner wall of the guide mounting hole 45. When the guide mounting post 46 abuts against the base plate between the pin, the variable diameter limiting post 40 is stuck and limited at the upper end of the guide mounting hole 45. Since the guide mounting post 46 and the variable diameter limiting post 40 are made of conductive materials, an electrical signal is generated when they come into contact. On the one hand, it is convenient to obtain information on whether the pin is intact and whether it is deformed. On the other hand, it can limit the movement of the pin during the welding process and dissipate heat in time to protect the electronic connector and improve the accuracy and quality of positioning welding.

[0074] After the positioning and welding of an electronic connector is completed, the angle of the deflection mounting cover 36 and the deflection mounting plate 12 on it is adjusted by the deflection drive shaft 35, so that the electromagnetic plate 39 rotates to the bottom and is energized. At this time, the guide mounting post 46 slides in the opposite direction. At this time, the electromagnetic induction chuck 47 makes the guide mounting post 46 and the variable diameter limiting post 40 stably adsorbed on the electromagnetic plate 39, which facilitates the positioning and welding operation of the next set of electromagnetic connectors.

[0075] The electrical signal generated by the contact between the guide mounting post 46 and the conductive layer inside the guide mounting hole 45 determines whether the guide mounting post 46 has completed its reset.
