Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wire welding, and in particular relates to a wire welding positioning mechanism. Background Technology
[0002] In the field of wire welding, such as Figure 1 As shown, there are two types of soldering: soldering where the wire is perpendicularly inserted into the circuit board hole, and soldering where the wire is parallel to the circuit board pad. Currently, for this type of product, the conventional soldering positioning method for through-hole soldering is to fix the circuit board to the workbench, use masking tape to stick the wire to the underside of the circuit board, and then carry out the soldering operation. This method has several drawbacks: First, the operation is cumbersome, requiring the application of masking tape for each wire placement, consuming significant manpower and time. Second, the use of masking tape creates a large gap between the wire and the circuit board, preventing the solder from fully filling the gap during welding, leading to poor welding conditions such as cold solder joints and detachment. Third, the masking tape's fixing effect on the wire is inadequate, making it difficult to ensure the wire is perpendicular to the circuit board after welding, failing to meet high-precision wire exit requirements. Fourth, this method can only fix a single wire at a time, making it impossible to place and weld multiple wires simultaneously, especially double-row wire placement and welding, limiting production efficiency. Furthermore, during the fixing of multiple wires, the small spacing between wires makes it easy for subsequent wire placement operations to touch the fixed wires, causing them to tilt and shift, affecting the overall welding quality. Moreover, the copper on the front of the circuit board's through-hole area requires heating the entire circuit board and wires during welding, posing a safety hazard as operators are easily burned when handling the wires.
[0003] With the trend of product miniaturization and precision, higher requirements are placed on the accuracy, efficiency and safety of wire and circuit board welding. The existing masking tape positioning method can no longer meet the industry's needs, and there is an urgent need for a new type of wire welding positioning mechanism to improve welding quality and production efficiency.

Detailed Implementation
[0038] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0040] like Figures 2 to 10 As shown, the wire welding positioning mechanism provided in this embodiment includes a base 1, a clamping assembly 2, a double-layer wire clamp 3, and a double-layer wire clamping assembly 4. The top of the base 1 has a first limiting groove 5. The clamping assembly 2 is installed on the top of the base 1, and its clamping end is located above the first limiting groove 5. The double-layer wire clamp 3 is detachably installed on the front side of the base 1 and is located below the first limiting groove 5. The double-layer wire clamping assembly 4 is detachably installed on the front side of the base 1 and is located below the double-layer wire clamp 3.
[0041] In use, the clamping assembly 2 is opened, and the circuit board is placed in the first limiting groove 5 at the top of the base 1. The first limiting groove 5 physically limits the circuit board in the front-back and left-right directions through its groove wall, ensuring that the circuit board is in the preset position. Subsequently, the clamping assembly 2 is closed, and its clamping end presses down to cooperate with the bottom of the first limiting groove 5, applying vertical constraint to the circuit board and achieving upper and lower limiting. At this point, the circuit board is fixed in all directions in three-dimensional space, avoiding displacement due to external forces during the soldering process and laying the foundation for high-quality soldering.
[0042] Install the double-layer wire clamp 3 to the front side of the base 1, below the first limiting groove 5, and open the double-layer wire clamp 3. The double-layer wire clamping assembly 4 is located below the double-layer wire clamp 3, and the two work together to complete the wire positioning. This embodiment takes the welding of double-layer wires (6 wires per layer) as an example, and adopts a layered, wire-by-wire positioning strategy:
[0043] Rear layer wire positioning: Starting with the rightmost wire in the rear layer, each wire is sequentially passed through the first layer of the double-layer wire clamping assembly 4 and the first layer of the double-layer wire clip 3, and inserted into the circuit board through-hole. After each wire is placed, the first layer of the double-layer wire clamping assembly 4 activates to secure the current wire. As subsequent wires are inserted, the first layer of the double-layer wire clamping assembly 4 continues to activate, stacking and positioning the already placed wires until all six rear layer wires are in place. Finally, the first layer of the double-layer wire clip 3 secures the entire row of rear layer wires.
[0044] Front layer wire positioning: Repeat the above process, using the second layer wire-clamping structure of the double-layer wire clamping assembly 4 and the second layer clamping structure of the double-layer wire clamp 3 to complete the positioning and fixing of the six front layer wires from right to left. Finally, the second layer clamping structure of the double-layer wire clamp 3 limits the overall positioning of the 12 wires in the front and back layers, ensuring that the wires are precisely aligned with the circuit board holes, and that the wires maintain a preset arrangement of horizontal spacing and layered distribution.
[0045] After the wires and circuit board are positioned, simultaneous soldering is performed. Once soldering is complete, the double-layer wire clamp assembly 4 releases its grip on the wires, and the clamping assembly 2 releases the circuit board. The operator can then tilt the circuit board, along with the double-layer wire clamp 3, upwards to remove it. Finally, the double-layer wire clamp 3 is opened to separate the wires from it, completing one soldering cycle.
[0046] This invention uses clamping component 2 to fix and limit the circuit board, combined with double-layer wire clamps 3 and double-layer wire clamping components 4 to double-fix and limit the wires. During welding, there is no need to hold the wires by hand, effectively solving problems such as unstable positioning and low efficiency in traditional wire welding. It ensures that the wires are perpendicular to the circuit board after welding, meeting the wire exit requirements. Simultaneously, the multi-layer structure design supports parallel welding of multiple wires, significantly improving production efficiency and welding consistency. Furthermore, it eliminates the need for masking tape, solving the problem of excessive gaps between the wires and the circuit board and ensuring welding stability.
[0047] The clamping assembly 2 includes a quick-release clamp 21 and a pressure plate 22. The quick-release clamp 21 is fixed to the top of the base 1, and the pressure plate 22 is detachably connected to the front end of the quick-release clamp 21. The pressure plate 22 is located above the first limiting groove 5. In this embodiment, the quick-release clamp 21 is model CH-201. The quick-release clamp 21 can quickly drive the pressure plate 22 to swing up and down, realizing the quick clamping and placement of the circuit board.
[0048] The clamping assembly 2 also includes a flexible block 23, which is disposed at the bottom of the pressure plate 22. In this embodiment, the flexible block 23 is a polyurethane block. The flexible block 23 prevents the pressure plate 22 from directly contacting the circuit board, and its cushioning effect protects the circuit board.
[0049] The system also includes a bearing 6, a first shaft 7, a limiting block 8, and a stop block 9. The front side of the base 1 has a second limiting groove 10. The double-layer wire clamp 3 is installed in the second limiting groove 10. The bearing 6 is fixed on the left and right sides of the base 1 of the second limiting groove 10. The rear end of the first shaft 7 is inserted into the bearing 6. The front end of the first shaft 7 is fixed with a limiting block 8. The limiting block 8 is located on the front side of the second limiting groove 10. The stop block 9 is fixed on the front side of the base 1 below the bearing 6.
[0050] Employing a simplified push-pull-toggle operation mode, when installing the double-layer cable clamp 3, simply toggle the limiting block 8 to rotate it around the first axis 7 away from the second limiting groove 10, and the double-layer cable clamp 3 can be quickly pushed into the second limiting groove 10. Then, toggle the limiting block 8 in the opposite direction to reset it, allowing it to swing to the front of the double-layer cable clamp 3 to form a limit position, requiring no additional tools or complex operating steps. Disassembly is performed by repeating the above reverse actions, significantly shortening the installation and disassembly time of the double-layer cable clamp 3. Compared with traditional screw-fixed or clip-on structures, operational efficiency is greatly improved, and labor costs are significantly reduced.
[0051] The limiting block 8 and the second limiting groove 10 work together to form a double limiting system. The limiting block 8 blocks the double-layer wire clamp 3 from moving forward, and the second limiting groove 10 constrains the displacement of the double-layer wire clamp 3 in the left, right and depth directions through the groove wall, ensuring that the double-layer wire clamp 3 has zero shaking during the welding process. Combined with the precise limitation of the swing angle of the limiting block 8 by the stop block 9, the risk of wire clamp loosening caused by excessive swing of the limiting block 8 is avoided, which greatly reduces the alignment accuracy error of the wire and the circuit board through hole and effectively improves the welding yield.
[0052] When installing the double-layer wire clamp 3, first move the limiting block 8 away from the second limiting groove 10, then push the double-layer wire clamp 3 into the second limiting groove 10. After pushing it in, move the limiting block 8 to swing it to the front of the double-layer wire clamp 3 to limit its movement. The stop block 9 blocks the swing of the limiting block 8, preventing it from swinging excessively. In this way, the double-layer wire clamp 3 can be quickly installed and removed with simple pushing, pulling, and moving actions.
[0053] The modular double-layer cable clamp 3 quick-release structure allows for rapid replacement of the adapter double-layer cable clamp 3 according to cable specifications and quantity, without changing the design of the base 1 and other components.
[0054] The double-layer wire clamp 3 includes a clamp base 31, a first clamp cover 32, a second clamp cover 33, a second shaft 34, a third shaft 35, a connecting arm 36, a torsion spring shaft 37, and a pressure block 38. The front side of the clamp base 31 has six first contouring grooves 39. The clamp base 31 on the left side of the first contouring groove 39 is rotatably connected to the second shaft 34, and the clamp base 31 on the right side of the first contouring groove 39 is rotatably connected to the third shaft 35. The left end of the first clamp cover 32 is fixed to the second shaft 34. The first clamp cover 32 has six second contouring grooves 310 on both its front and rear sides. The second contour groove 310 on the rear side and the first contour groove 39 form a first wire clamping channel 311. The left end of the second clamping cover 33 is fixed to the second shaft 34. The rear side of the second clamping cover 33 has 6 third contour grooves 312. The second contour groove 310 on the front side of the first clamping cover 32 and the third contour groove 312 form a second wire clamping channel 313. The rear end of the connecting arm 36 is fixed to the third shaft 35. The other front end of the connecting arm 36 passes through the second clamping cover 33 and is rotatably connected to the pressure block 38 through the torsion spring shaft 37. The pressure block 38 is located on the front side of the second clamping cover 33.
[0055] To open the double-layer wire clamp 3, pry the pressure block 38 forward, then swing the connecting arm 36 to the right, causing the pressure block 38 to release its restraint on the second clamp 33. Then, the second clamp 33 and the first clamp 32 can be opened. After the rear layer of wires is placed, push the first clamp 32 backward to fix and restrain the rear layer of wires. After the front layer of wires is placed, push the second clamp 33 backward to fix and restrain the front layer of wires. Finally, swing the connecting arm 36 to the left to release the pressure block 38. Under the action of the torsion spring shaft 37, the pressure block 38 presses the second clamp 33, effectively and stably fixing and restraining the double-layer wires.
[0056] Employing a double-clamping cap and contoured groove structure, the first clamping channel 311 and the second clamping channel 313 tightly fit the shape of the wire, achieving 360° wrap-around clamping of the wire in the circumferential direction. Regardless of whether the wire has a round, flat, or elliptical cross-section, the contoured groove can precisely adapt to it, effectively preventing wire displacement and shaking during welding, ensuring welding position accuracy, and significantly improving yield.
[0057] Through the linkage unlocking mechanism of the pressure block 38 and the connecting arm 36, the first clamp 32 and the second clamp 33 can be simultaneously released by only two steps: prying the pressure block 38 and swinging the connecting arm 36, thus achieving rapid opening of the double-layer wire clamp 3. When closing, the connecting arm 36 is swung in the opposite direction and the pressure block 38 is released. The torsion spring shaft 37 automatically drives the pressure block 38 to press the second clamp 33, forming a mechanical self-locking mechanism. Compared with traditional screw-fastening or snap-on wire clamps, the operation time is greatly shortened, the wire clamping efficiency is significantly improved, and the manual operation intensity is reduced.
[0058] The layered clamp design enables independent positioning and fixation of the front and rear layers of wires. The rear layer of wires is locked by the first clamping channel 311 formed by the first clamp 32 and the clamp 31, while the front layer of wires is limited by the second clamping channel 313 formed by the second clamp 33 and the first clamp 32, ensuring that the two layers of wires do not interfere with each other and are precisely aligned with the circuit board holes. Finally, the pressure block 38 presses the second clamp 33 to rigidly fix the two layers of wires as a whole, forming a stable three-dimensional clamping structure that can withstand the high temperature thermal stress and external impact during the soldering process, preventing the wires from shifting or loosening.
[0059] The double-layer cable clamping assembly 4 includes a bolt 41, a cable clamping base 42, a guide rail 43, and a slider 44. The cable clamping base 42 and the guide rail 43 are detachably connected to the front side of the base 1 by the bolt 41. The front side of the cable clamping base 42 has 6 cable clamping slots 45. The cable clamping base 42 on the left and right sides of the cable clamping slots 45 has a forward-protruding side plate 46. The side plate 46 has two insertion holes 47 arranged at intervals. The guide rail 43 has two slides 48 arranged at intervals. Each slide 48 is slidably connected to a slider 44. The two sliders 44 pass through the two insertion holes 47 respectively.
[0060] The double-layer wire clamping assembly 4 is based on a dual-rail, dual-slide bar 44 step-by-step clamping mechanism, which achieves precise wire positioning through mechanical limiting and progressive advancement:
[0061] Rear layer cable positioning process: After placing the first cable on the right side of the rear layer, push the rear slider 44 to the left so that it passes through the rear insertion hole 47 of the right side plate 46 until the front end of the slider 44 presses against the front of the cable. The cable is then positioned by the cable locking groove 45 and the slider 44. For each additional cable, continue to move the slider 44 to the left so that its front end covers and fixes all the placed cables in sequence. After all 6 cables in the rear layer are placed, insert the left end of the slider 44 into the rear insertion hole 47 of the left side plate 46 to complete the overall positioning of the rear layer.
[0062] Front layer wire positioning process: Repeat the above steps, but use the front slide bar 44 and the front socket 47; the front slide bar 44 and the rear slide bar 44 work together to form a double-layer independent limiting system.
[0063] By removing bolt 41, different specifications of cable holder 42 (such as adjusting slot width and spacing) or guide rail 43 can be replaced to meet the needs of multiple scenarios.
[0064] The front and rear slide bars 44 of the double-layer wire clamping assembly 4 operate independently to prevent interlayer interference, ensuring that the double-layer wires are arranged in parallel and perpendicular to the circuit board, thus improving the soldering yield. Each wire only requires pushing the slide bar 44 once, significantly reducing operation time compared to the traditional method of fixing wires one by one. The slide bar 44 automatically covers the placed wires during the advancement process, realizing one-wire-one-clamping, greatly reducing repetitive work. The insertion holes 47 of the side plate 46 form a physical constraint on the slide bar 44 to prevent displacement caused by vibration during soldering. The stroke of the slide bar 44 and the position of the wire clamping groove 45 are pre-designed to eliminate human interference and ensure product consistency between batches.
[0065] The double-layer cable clamping assembly 4 also includes a limiting post 49, which is fixed inside the slide rail 48. The slide bar 44 has a strip-shaped hole 410, through which the limiting post 49 passes. The cooperation between the limiting post 49 and the strip-shaped hole 410 restricts the movement of the slide bar 44 and prevents it from moving excessively.
[0066] The double-layer cable clamping assembly 4 also includes a handle 411, which is provided on the outer end of the slider 44. The handle 411 facilitates pushing the slider 44.
[0067] The system includes a mounting frame 11, a first crossbar 12, and a second crossbar 13. The mounting frame 11 is detachably connected to one side of the base 1. The mounting frame 11 is fixed with the first crossbar 12 and the second crossbar 13, which are spaced apart. The first crossbar 12 is located in front of the second crossbar 13, and the second crossbar 13 is located in front of the first limiting groove 5. The axis of the first crossbar 12 is located above the axis of the second crossbar 13. This double-crossbar limiting structure creates an upper and lower clamping space between the first crossbar 12 and the second crossbar 13. After the wire passes through the gap between them, it is forcibly constrained to a horizontal state. The second crossbar 13 provides bottom support to counteract the sagging or tilting caused by the weight of the wire. The first crossbar 12 restricts the wire's deviation from above. Compared to traditional manual placement, this improves welding position accuracy and effectively avoids problems such as incomplete soldering and misaligned soldering.
