Description

Technical Field

[0001] This utility model belongs to the field of wire welding technology, and in particular relates to a wire clamping device and a welding mechanism. Background Technology

[0002] On the production line, when soldering the end of a wire to a circuit board, if the end of the wire is bent, it can easily cause misalignment between the end of the wire and the pads on the circuit board, affecting the soldering quality. In severe cases, it can lead to problems such as cold solder joints or false solder joints, reducing the assembly pass rate of electronic products. Taking the scenario of soldering the wire of a headset to a circuit board as an example, the wire of a headset is usually thin and flexible. If the end of the wire is bent before soldering, it will cause misalignment between the wire and the pads during soldering. Under current technological conditions, to solve the problem of bent ends on production lines, some production lines use manual methods to straighten the ends before subsequent cutting, welding, and other operations. However, this manual method is inefficient. Utility Model Content

[0012] On the production line, when the end of the line is soldered to the circuit board, if the end of the line is bent, the end of the line is prone to misalignment with the pads on the circuit board, which will affect the soldering quality. In severe cases, it may also lead to problems such as cold solder joints and false solder joints, reducing the assembly qualification rate of electronic products.

[0013] Under current technological conditions, to solve the problem of bent ends on production lines, some production lines use manual methods to straighten the ends before subsequent cutting, welding, and other operations. However, this manual method is inefficient.

[0014] In view of this, the present invention provides a wire clamping device, which aims to solve the problem of low efficiency in manually clamping the end of a straight body L in the prior art.

[0015] Please see Figure 1 and Figure 2 The wire clamping device 100 includes a base 1, a positioning component 2, and a straightening component 3. The positioning component 2 is disposed on the base 1, and the straightening component 3 allows the base 1 to move. The wire body L has a first segment L1 and a second segment L2 that are independent of each other in the length direction. The positioning component 2 is used to clamp the first segment L1 of the wire body L to position the first segment L1, preventing the wire body L from shifting as a whole during processing. The straightening component 3 is movable relative to the base 1, thus having a first position relative to the base 1 (e.g., ...). Figure 1 and Figure 4 (as shown) and the second position (as shown) Figure 5 (As shown). When the straightening assembly 3 is in the first position, it can clamp the second segment L2 of the wire body L. By applying a stable clamping force to the second segment L2, it straightens the second segment L2, which may have been bent, keeping it in a straight state and providing good preconditions for subsequent welding and other processes. When the straightening assembly 3 is in the second position, it will disengage from the second segment L2 of the wire body L, thus freeing up the second segment L2 and facilitating subsequent processing of the straightened second segment L2 by the operating equipment. Preferably, the straightening assembly 3 can free up the surrounding space of the second segment L2 (such as the space below the second segment L2 and the side space away from the first segment L1) while freeing up the second segment L2.

[0016] The clamping and straightening assembly 3 can move relative to the base 1 in various ways, including rotation, sliding, and telescopic movement. For example, if the production line space is relatively compact, a rotational movable connection can be used, whereby the clamping and straightening assembly 3 rotates around the hinge axis of the base 1 or the positioning assembly 2 to switch between the first and second positions. If the clamping and straightening assembly 3 needs to be displaced in a straight line to accommodate different lengths of line body L or different positions of welding pads, then a sliding movable connection is more suitable. The smoothness and accuracy of the movement of the clamping and straightening assembly 3 can be improved through the cooperation of the slide rail and the slider. In addition, a telescopic movable connection can be driven by a cylinder, hydraulic cylinder, or electric push rod to drive the clamping and straightening assembly 3 to extend and retract axially, thereby switching between the first and second positions.

[0017] When it is necessary to straighten the cable L, the straightening component 3 of the cable clamping device 100 must first be adjusted to the first position (clamping position) before assembling the cable L. Taking the processing scenario of the headphone cable L as an example, the segmentation of the cable L can be clearly defined: the fixed end segment near the headphone headband is defined as the first segment L1 (no further processing is required, but stable positioning is necessary), and the free end segment away from the headphone headband is defined as the second segment L2 (which needs to be straightened, cut, and then welded, and is the core processing segment).

[0018] The specific procedure for the straightening operation is as follows: First, use tweezers (or automated machine grippers) to grasp the free end of the wire body L, that is, the end near the second wire segment L2. Then, along the extension direction of the wire body L of the wire clamping device 100 (i.e., the first direction, in...) Figure 2 (represented by dashed line a) The entire line body L is placed smoothly into the clamping device 100: the first segment L1 (head beam end) of the line body L is completely embedded in the positioning component 2, and stable fixation is achieved by the clamping force of the positioning component 2; at the same time, the second segment L2 (free end) of the line body L is placed in the clamping groove of the straightening component 3.

[0019] After the clamping and straightening assembly 3 completes the clamping and straightening correction of the second line segment L2 at the first position, the movable mechanism of the clamping and straightening assembly 3 is activated to move it from the first position to the second position (disengagement position, such as...). Figure 5 (As shown). At this point, the clamping assembly 3 is completely separated from the second line segment L2 (preferably, it is moved to an area that does not obstruct the processing path, completely freeing up the operating space of the second line segment L2), preparing for the subsequent cutting process.

[0020] Please continue reading. Figure 5 Since the end of the thread L that was previously gripped by tweezers or a machine may have been slightly bent due to the gripping force, this part of the end needs to be cut off to ensure the straightness of the processed end of the thread L. At this time, the thread clamping device 100, along with the positioned thread L, can be transferred as a whole to the working area of ​​the cutting device. The relative positions of the two are adjusted so that the part of the second thread segment L2 to be cut is aligned with the blade of the cutting tool (the blade position is within...). Figure 5 (Indicated by dashed lines and up / down arrows). Because the clamping component 3 is in the avoidance position, the cutting edge of the cutting tool can directly act on the part to be cut.

[0021] Please combine Figure 6 and Figure 7 After the wire L is cut, there is no need to remove the wire L from the clamping device 100. The clamping device 100 and the wire L are directly brought close to the welding device 200. With the help of the clamping device 100 to stably position the first wire segment L1, the position of the clamping device 100 is adjusted so that the end of the straightened and cut second wire segment L2 is aligned with the target pad on the circuit board 300, preparing for subsequent welding.

[0022] In summary, the wire clamping device 100 provided in this embodiment includes a base 1, a positioning component 2, and a straightening component 3. The positioning component 2 is disposed on the base 1 and is used to clamp a first segment L1 of the wire body L to position the first segment L1. The straightening component 3 is movable relative to the base 1, having a first position and a second position relative to the base 1. In the first position, the straightening component 3 clamps a second segment L2 of the wire body L to straighten the second segment L2. In the second position, the straightening component 3 disengages from the second segment L2 of the wire body L to free the second segment L2. This embodiment, through the positioning component 2, enables the wire body L to be positioned on the wire clamping device 100; and through the clamping action of the straightening component 3 on the second segment L2 in the first position, it achieves automated straightening of the second segment L2, replacing manual straightening operations and improving straightening efficiency. Meanwhile, the clamping and straightening component 3 can detach at the second position, freeing up the second line segment L2 and providing operating space for subsequent cutting, welding, and other processes. This avoids interference from the clamping and straightening component 3 with subsequent processes and ensures the smoothness of the entire processing flow. This structural design allows the clamping and straightening of line L and subsequent processing steps to be seamlessly connected, which is beneficial for improving the automation level and overall production efficiency of the production line.

[0023] In some embodiments, please refer to Figure 2 To reduce rigid compression damage to the line L, the positioning component 2 includes a first base 21 and a first clamping member 22 disposed on the first base 21. The first base 21 is disposed on the base 1, and the first clamping member 22 is used to clamp the first line segment L1 of the line L. The first clamping member 22 is a first silicone part. And / or, the straightening component 3 includes a second base 31 and a second clamping member 32 disposed on the second base 31. The second base 31 is movably connected to the base 1 or the first base 21, and the second clamping member 32 is used to clamp the second line segment L2 of the line L. The second clamping member 32 is a second silicone part.

[0024] Using silicone as the clamping material allows for sufficient clamping force on the cable L while avoiding physical damage such as scratches and pressure marks caused by direct contact between hard materials such as metal and the cable L surface. It is especially suitable for cables L with an outer layer of insulating rubber or a softer material.

[0025] The first seat 21 and the second seat 31 serve as connections. The first seat 21 stably mounts the first clamping member 22 on the base 1, ensuring that the positioning component 2 will not shake or shift when clamping the first line segment L1 of the line body L, providing a solid support foundation for the overall positioning of the line body L. The second seat 31 is connected to the base 1 or the first seat 21 through a movable connection (such as hinge, sliding, etc.), so that the straightening component 3 can flexibly switch between the first position and the second position to meet different working requirements of clamping, straightening, and disengaging.

[0026] In some embodiments, please refer to Figure 2 and Figure 3 Considering the convenience of placing the line L, a top-down placement method is adopted. The corresponding structure is set such that the first clamping member 22 forms a first groove 2221 with the opening facing upward, and the second clamping member 32 forms a second groove 3221 with the opening facing upward. When the clamping assembly 3 is in the first position, the side walls of the first groove 2221 and the second groove 3221 are both through along the first direction, and the bottom wall of the first groove 2221 is flush with the bottom wall of the second groove 3221.

[0027] This structural design allows operators or automated equipment to directly place the first segment L1 and the second segment L2 of the line L into the first groove 2221 and the second groove 3221 respectively from above when placing the line L, eliminating the need for complex alignment operations and improving the convenience and efficiency of clamping the line L. Simultaneously, the flush bottom walls of the first groove 2221 and the second groove 3221 ensure that the line L is on the same horizontal line along its length, preventing unnecessary bending or stress caused by height differences and improving the stability of the clamping effect.

[0028] In some embodiments, please refer to Figure 3 and Figure 4 Considering the case of multiple wire bodies L, in order to improve production efficiency, multiple first grooves 2221 and second grooves 3221 are respectively arranged at intervals along a second direction, which is perpendicular to the first direction; the first grooves 2221 and second grooves 3221 are arranged one-to-one in the first direction, so that multiple first grooves 2221 respectively clamp the first segment L1 of multiple wire bodies L, and multiple second grooves 3221 respectively clamp the second segment L2 of multiple wire bodies L. In the second direction, Figure 2 The dashed line 'b' represents the middle part.

[0029] This multi-groove design allows the wire clamping device 100 to simultaneously position and straighten multiple wires L, making it particularly suitable for circuit board 300 processing scenarios where multiple wires L need to be soldered simultaneously. For example, on the circuit board 300 of headphones, multiple wires L with different functions, such as left and right channel wires and microphone wires, typically need to be soldered. The wire clamping device 100 with its multi-groove structure can straighten and position all wires L at once, avoiding the tedious process of processing each wire L one by one, and significantly improving the overall efficiency of the multi-wire L soldering process. At the same time, the multiple first grooves 2221 and second grooves 3221 correspond one-to-one in the first direction, ensuring that the first segment L1 and the second segment L2 of each wire L are on the same straight line, preventing tangling or misalignment between wires L, and providing precise positioning assurance for subsequent simultaneous cutting and soldering of multiple wires L.

[0030] In some embodiments, please refer to Figure 2 and Figure 3 The first clamping member 22 is a first silicone part. However, silicone parts are prone to deformation, so a third clamping member 23 with a higher hardness than the first silicone part is added. Specifically, the third clamping member 23 is also mounted on the first base 21, and its top is designed with an upward-facing third groove 2321. The side wall of the third groove 2321 extends along the first direction and is used to position the connection between the first line segment L1 and the second line segment L2 of the line body L; in addition, the bottom wall of the third groove 2321 is flush with the bottom wall of the first groove 2221.

[0031] The third clamping member 23 can be a hard plastic part or a metal part. The third clamping member 23 provides additional rigid support and positioning for the connection between the first line segment L1 and the second line segment L2, in addition to the elastic clamping of the first line segment L1 by the first silicone part. To avoid scratching the line L, the width of the third groove 2321 can be slightly larger than the diameter of the line L, so that it only serves to limit the line L rather than tightly clamp it. This prevents damage to the line L due to rigid contact and also prevents displacement due to deformation of the silicone part, improving the overall positioning stability of the line L and the straightening effect of the straightening component 3 on the second line segment L2.

[0032] In some embodiments, please continue reading Figure 2 and Figure 3Based on the first clamping member 22 being a first silicone part, a detachable installation method is adopted to facilitate the replacement of the first clamping member 22; however, since it is not convenient to drill threaded holes in the first silicone part, a third clamping member 23 is used to press the first silicone part to achieve installation and fixation; specifically, the first clamping member 22 includes a first body 221 and a first clamping part 222 disposed at the top of the first body 221, a first stepped surface 223 is formed between the first body 221 and the first clamping part 222, and a first groove 2221 is formed at the top of the first clamping part 222; wherein, the bottom end face of the third clamping member 23 is pressed against the first stepped surface 223.

[0033] This design uses the cooperation between the third clamping member 23 and the first stepped surface 223 to press and fix the first silicone part onto the first base 21, eliminating the need for threaded holes in the first silicone part and simplifying its structural design and manufacturing complexity. When the first silicone part wears or ages due to long-term use and needs replacement, simply remove the third clamping member 23 from the first base 21 to easily remove the old first silicone part and replace it with a new one, making the operation convenient and reducing maintenance costs. Simultaneously, the pressing action of the third clamping member 23 on the first silicone part further enhances its stability when clamping the line L, preventing displacement or deformation under stress and ensuring consistently reliable clamping of the first segment L1 of the line L.

[0034] Furthermore, a positioning hole can be injection molded into the bottom of the first silicone part, and a positioning pin can be inserted into the first base 21. Part of the positioning pin is inserted into the first base 21, and the other part is embedded in the positioning hole of the first silicone part. Through the cooperation of the positioning pin and the positioning hole, the installation position of the first silicone part on the first base 21 can be positioned, thereby preventing the first silicone part from shifting laterally after being pressed and fixed.

[0035] In some embodiments, please continue reading Figure 2 and Figure 3 Considering that the groove may not completely position the line L and there is still a tendency for it to move upward, a limiting cover plate 24 is added. Specifically, the third clamping member 23 includes a third body 231 and a third clamping part 232 disposed on the top of the third body 231. A third stepped surface 233 is formed between the third body 231 and the third clamping part 232. A third groove 2321 is formed on the top of the third clamping part 232. The bottom end face of the third body 231 is pressed against the first stepped surface 223. The third stepped surface 233 is used to support the line L. The positioning component 2 also includes a limiting cover plate 24, which is movably disposed above the third stepped surface 233 to restrict the upward movement of the line L.

[0036] The limiting cover 24 can be connected to the third clamping member 23 or the first base 21 via a hinge to achieve flip-opening and closing. Alternatively, it can slide along an axis perpendicular to the first direction using a slide rail structure, thereby exposing or covering the third step surface 233. After the wire L is placed into the first groove 2221, the second groove 3221, and the third groove 2321, the limiting cover 24 is moved to the covering position, with its lower surface slightly contacting or maintaining a small gap with the upper surface of the wire L. This prevents the wire L from jumping out of the grooves due to vibration or external force during processing, while also preventing excessive compression of the wire L. For example, when the straightening assembly 3 moves to the second position, the limiting cover 24 can prevent the wire L from moving upwards due to the movement of the straightening assembly 3. Or, when the wire clamping device 100 is transferred to the shearing or welding area, the limiting cover 24 can prevent the wire L from shifting upwards due to inertia, further improving the stability of the wire L's positioning. Meanwhile, the movable design of the limiting cover 24 also ensures the convenience of placing and removing the line L. When the line L needs to be placed, the cover is opened, and the cover is closed after the line L is positioned.

[0037] In some embodiments, please continue reading Figure 2 and Figure 3 Based on the second silicone part being the second clamping member 32, a detachable installation method is adopted to facilitate the replacement of the second silicone part; however, since it is inconvenient to drill threaded holes in the second silicone part, a pressure plate 33 is added to press the second silicone part to achieve installation and fixation; specifically, the second clamping member 32 includes a second body 321 and a second clamping part 322 disposed at the top of the second body 321, a second stepped surface 323 is formed between the second body 321 and the second clamping part 322, and a second groove 3221 is formed at the top of the second clamping part 322; wherein, the bottom end face of the pressure plate 33 is pressed against the second stepped surface 323, and the height of the top surface of the pressure plate 33 is lower than or equal to the height of the bottom wall of the second groove 3221.

[0038] The pressure plate 33 can be fixed to the second base 31 by bolts or clips. While pressing and fixing the second silicone part, it avoids interfering with the placement of the line body L by having its own structure higher than the bottom wall of the second groove 3221. The function of the pressure plate 33 is similar to that of the third body 231 of the third clamping member 23. Both achieve convenient installation and fixing of the silicone clamping member through the cooperation of the stepped surface with the pressure member. This solves the problem that silicone parts are difficult to fix directly by threaded connection, ensures the stability after installation, and facilitates subsequent maintenance and replacement.

[0039] In some embodiments, please refer to Figure 4 and Figure 5In order to allow the clamping assembly 3 to make room for the second line segment L2, and also to make room for the surrounding space of the second line segment L2; specifically, the second seat 31 is hinged to the first side 211 of the first seat 21 along the second direction, the second direction being perpendicular to the first direction; and the first side 211 is formed with a receiving notch 2111 for accommodating the clamping assembly 3; wherein, in the first position, the clamping assembly 3 is away from the receiving notch 2111, so that the groove wall of the second groove 3221 clamps the second line segment L2 of the straight body L; in the second position, the clamping assembly 3 enters the receiving notch 2111, so as to make room for the space below the second line segment L2.

[0040] This hinged structure design allows the clamping straightening component 3 to flip and switch between a first position and a second position around the hinge axis. When the clamping straightening component 3 is in the second position and enters the receiving notch 2111, not only does the clamping straightening component 3 itself separate from the second line segment L2, but its overall structure can also sink into the receiving notch 2111, thereby fully releasing the space below the second line segment L2 and avoiding obstruction to the cutting tool approaching the part to be cut from below or from the side. For example, in the cutting process, if the cutting tool needs to perform an upward cutting operation from below the second line segment L2, the clamping straightening component 3 in the receiving notch 2111 will not interfere with the movement path of the cutting tool, ensuring that the cutting action can be completed smoothly. At the same time, the hinged method has the characteristics of simple structure and reliable operation, and can quickly realize the position switching of the clamping straightening component 3, improving the overall operating efficiency of the wire clamping device 100 and the smoothness of process connection.

[0041] Furthermore, to ensure the straightening assembly 3 is stable in both the first and second positions, a magnetic attraction component can be added. Specifically, magnets are installed at corresponding positions on the second base 31 and the first base 21. When the straightening assembly 3 is flipped to the first position, the magnet on the second base 31 attracts the magnet on the first base 21, and the resulting magnetic force stabilizes the straightening assembly 3 in the working position, preventing accidental rotation of the straightening assembly 3 due to vibration or external force during the straightening of the second line segment L2. When it is necessary to switch the straightening assembly 3 to the second position, a certain flipping force is applied to overcome the magnetic force, allowing the straightening assembly 3 to rotate around the hinge axis and enter the receiving notch 2111. When the straightening assembly 3 is flipped to the second position, another magnet on the second base 31 attracts the other magnet on the first base 21, thereby stabilizing the straightening assembly 3 in the avoidance position and preventing it from affecting the operating accuracy due to shaking during subsequent shearing or welding processes.

[0042] This utility model embodiment also provides a welding mechanism.

[0043] Please see Figure 1 , Figure 6 and Figure 7The welding mechanism includes a welding device 200 and a wire clamping device 100 provided in any of the above embodiments. A circuit board 300 can be mounted on the welding device 200. The straightening assembly 3 is in a second position so that the second segment L2 of the wire body L extends to the pad of the circuit board 300. The welding device 200 is used to weld the second segment L2 of the wire body L to the pad.

[0044] When the straightening component 3 of the wire clamping device 100 is in the second position and the second wire segment L2 is cleared, the wire L, driven by the wire clamping device 100, approaches the circuit board 300 mounted on the welding device 200, and precisely aligns the second wire segment L2 with the pad on the circuit board 300. The welding head of the welding device 200 can move to the pad position, and through high-temperature melting of solder or the metal part of the wire L, achieves electrical connection and mechanical fixation between the second wire segment L2 and the pad. Since the wire clamping device 100 has pre-completed the straightening and positioning of the wire L, welding defects such as cold solder joints and short circuits caused by bending or offset of the wire L are reduced.

[0045] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
