Description

Technical Field

[0001] This invention relates to the field of wire welding technology, and in particular to a microphone wire welding processing equipment. Background Technology

[0002] In the microphone manufacturing process, the microphone head is an important component. The microphone head is connected to the motherboard via a cable, and the connection between the microphone head and the cable is made by soldering. The quality of the soldering directly determines the microphone's audio transmission performance, lifespan, and stability.

[0003] Currently, the soldering of microphones and cables typically employs automated soldering equipment. The microphone is placed at the soldering position, and the two branch wires within the cable are soldered to the microphone using a soldering method. However, due to external environmental factors or the soldering equipment itself, defects such as incomplete soldering and missing solder joints occur at the solder joints between the cable and the microphone. This can easily lead to audio interruptions and poor contact during microphone use. Furthermore, existing soldering equipment usually employs X... X-ray and ultrasonic testing are used to inspect the weld joints after processing. However, these methods can only observe the appearance and internal voids of the weld joints and lack an effective mechanism for testing weld strength. They cannot directly verify the actual mechanical connection strength of the weld joints and cannot solve the problem of poorly welded joints that appear normal but are prone to breakage under stress. Some testing methods can only test the overall connection strength between the wire and the microphone, such as manually randomly selecting microphones for pulling tests. This method not only results in the possibility of operators applying excessive force and damaging the wire, but also makes it impossible to accurately identify poorly welded or missing welds in individual branches, thus affecting the overall welding quality and reducing the welding effect. Furthermore, when welding defects are detected, it is necessary to manually reposition the wire and microphone and perform a second welding, which not only increases the labor intensity but also significantly reduces production efficiency.

[0004] Therefore, there is an urgent need to provide microphone cable welding equipment that can improve the welding effect and efficiency between the cable and the microphone head. Summary of the Invention

[0005] Therefore, it is necessary to provide a microphone wire welding processing equipment to solve the technical problems mentioned in the background art.

[0008] The line end support includes a positioning frame connected to the moving part. A line-pulling plate is installed inside the positioning frame. Two rotating blocks are hinged to the rear end of the line-pulling plate. An arc-shaped sliding rod is installed at the lower end of the rotating blocks and slides through the bottom wall of the positioning frame.

[0009] The microphone cable welding processing equipment also includes a placement unit, which is set on the workbench surface. The placement unit includes a placement part for placing the microphone and a clamping part that cooperates with the placement part for clamping the microphone.

[0010] After welding, the moving part drives the wire to rise, the placement unit maintains the clamping limit on the microphone, the wire is subjected to force to press the rotating block, the rotating block squeezes the force measuring component through the arc-shaped slide rod, when the force measuring component measures the pressure to the rated value, the placement part releases the limit on the microphone, when the pressure is not reached, the moving part drives the wire to fall, and the welding module re-welds the end of the wire.

[0011] Preferably, the placement unit further includes a positioning platform installed on the upper part of the workbench surface, and an alignment plate is detachably installed on the upper part of the positioning platform.

[0012] Preferably, the moving part includes a fixed platform installed on the upper part of the workbench surface, a driving component one is installed on the fixed platform, a driving component two is installed on the upper part of the driving component one, a moving platform is installed on the driving component two, and a wire feeding plate with a wire feeding groove one at the upper end is detachably installed on the moving platform.

[0013] Preferably, the line end support portion further includes return springs respectively installed at the lower ends of the two rotating blocks, with the lower ends of the return springs fixedly connected to the bottom wall of the positioning frame.

[0014] Preferably, the force measuring component includes a mounting plate installed at the lower end of the positioning frame, and two pressure sensors that respectively cooperate with the lower ends of the two arc-shaped sliding rods are mounted on the mounting plate.

[0015] Preferably, the clamping part includes a driving component three mounted on the mobile platform. A connecting plate is mounted on the upper end of the driving component three, and a support frame is mounted on the lower end of the connecting plate away from the driving component three. Two lifting rods are slidably mounted on the support frame. A clamping strip is mounted on the lower end of the lifting rods, and a connecting spring is mounted between the lower end of the lifting rods and the support frame.

[0016] Preferably, the placement part includes a placement bucket mounted on the upper end of the positioning platform. The placement bucket is provided with a plurality of circumferentially evenly distributed clamping blocks. At least one sliding rod is installed at the end of the clamping block away from the axis of the placement bucket. The sliding rod slides through the wall of the placement bucket and is equipped with a guide block. A telescopic spring is installed between the guide block and the outer ring surface of the placement bucket.

[0017] Preferably, the clamping part includes a driving component four installed at the rear end of the positioning platform. A lower pressure plate is installed on the upper end of the driving component four. A circular hole is opened in the middle of the lower pressure plate, and the circular hole is coaxially distributed with the placement bucket.

[0018] Preferably, the upper end of the cable tray has two symmetrical cable feeding slots, which are arranged in a V-shape.

[0019] Preferably, the upper end of the rotating block is provided with a wire-laying groove for placing the end of the wire.

[0020] Preferably, the lower end of the clamping strip is provided with a clamping groove, and the clamping strip is located above the hinge point between the cable tray and the rotating block.

[0021] In summary, the present invention has the following beneficial technical effects: 1. The wire clamping unit and the placement unit used in the present invention can cooperate to simultaneously detect the connection strength of the two branch wires of the wire to the microphone welding position after the wire is welded to the microphone. Moreover, the detection of the two branch wires is mutually exclusive, accurately detecting the welding strength of a single branch wire, realizing independent judgment of the connection strength of a single branch wire, effectively avoiding the situation where a single branch wire is poorly welded but the whole is not detected, ensuring welding quality; and can also directly verify the actual mechanical connection strength of the weld point, unaffected by the external and internal conditions. Specifically, after welding, two independently set rotating blocks, arc-shaped sliding rods, pressure sensors and reset springs can detect the connection strength of the two branch wires to the microphone separately. During the detection process, the clamping strip is always limited by the connecting spring to prevent the branch wire from deviating, providing a precise positioning basis for secondary welding.

[0022] 2. The wire clamping unit and placement unit used in this invention integrate the wire-microphone connection strength detection step into the necessary steps of microphone material handling, without adding an additional separate detection step, thus ensuring welding efficiency. When a welding defect is detected, the equipment can automatically drive the wire to reset and perform secondary welding without manual repositioning of the wire, significantly improving the efficiency of secondary welding and avoiding material waste.

[0023] 3. The clamping strip used in this invention elastically clamps the branch wire insulation sheath through a connecting spring, which not only ensures the stability of the limit position but also avoids damage to the wire caused by rigid compression. During strength testing, the rotating block is tilted under force, which can prevent relative sliding between the branch wire and the outer insulation sleeve, further protecting the structural integrity of the wire.

[0034] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways not described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] See Figure 1 and Figure 2 A microphone wire soldering processing equipment includes a workbench 1, a control module 2 and a soldering module 3 installed on the surface of the workbench 1. The control module 2 is an existing data processing control center, and the soldering module 3 is an existing microphone soldering device (soldering gun). A motion controller (existing technology) for controlling the movement of the soldering module 3 is also installed on the workbench 1. Both the motion controller and the soldering module 3 are electrically connected to the control module 2.

[0036] See Figure 1 , Figure 2 and Figure 3 The microphone wire welding processing equipment also includes a placement unit 5 disposed on the table surface of the workbench 1. The placement unit 5 includes a placement part 50 for placing the microphone and a clamping part 51 that cooperates with the placement part 50 and is used to clamp the microphone. The placement unit 5 also includes a positioning platform 52 installed on the upper part of the table surface of the workbench 1.

[0037] See Figures 1-4 The placement part 50 includes a placement bucket 500 installed on the upper end of the positioning platform 52. The placement bucket 500 is provided with a plurality of circumferentially evenly distributed clamping blocks 501. Two sliding rods 502 are installed at the end of the clamping block 501 away from the axis of the placement bucket 500. The sliding rods 502 slide through the wall of the placement bucket 500 and are equipped with guide blocks 503. The guide blocks 503 have inclined surfaces. A telescopic spring 504 is installed between the guide blocks 503 and the outer ring surface of the placement bucket 500.

[0038] In the initial state, multiple circumferentially distributed clamping blocks 501 are attached to the inner wall of the placement bucket 500. The upper end of each clamping block 501 is provided with an arc-shaped surface to guide and assist the placement of the microphone. Before welding, the microphone is placed in the placement bucket 500 by manual labor or existing robotic arms. The welding point at the upper end of the microphone in the placement bucket 500 is in the working position of the welding module 3.

[0039] See Figure 1 , Figure 3 and Figure 4The clamping part 51 includes a driving component 4 510 installed at the rear end of the positioning platform 52. A lower pressure plate 511 is installed on the upper end of the driving component 4 510. A circular hole is opened in the middle of the lower pressure plate 511, and the circular hole is coaxially distributed with the placement bucket 500.

[0040] The driving component 4 510 can be any existing linear drive device such as a hydraulic push rod or an electric push rod, and is not limited to any one of them. All of them are connected to the control module 2 via electrical signals. In the initial state, the circular hole of the lower pressure plate 511 is fitted around the outer periphery of the placement bucket 500 and is located above multiple guide blocks 503. After the microphone is placed into the placement bucket 500, the driving component 4 510 is activated. The driving component 4 510 drives the lower pressure plate 511 to move downward. The lower pressure plate 511 pushes the inclined surfaces on multiple guide blocks 503 through the wall of the circular hole. The multiple guide blocks 503 are subjected to force and drive multiple clamping blocks 501 to move towards the microphone through the corresponding sliding rods 502 and clamp and limit the microphone. At the same time, the guide blocks 503 compress the corresponding telescopic springs 504. Then the operation of the driving component 4 510 is stopped. The movable guide blocks 503 can realize the change of clamping space and can clamp and limit microphones of different sizes within a certain range.

[0041] See Figure 1 and Figure 3 The positioning platform 52 is detachably mounted with an alignment plate 53 by bolts on its upper end, and the alignment plate 53 is located on one side of the placement bucket 500.

[0042] See Figures 1-5 The microphone wire welding processing equipment also includes a wire clamping unit 4. The wire clamping unit 4 includes a movable part 40 disposed on the table surface of the workbench 1. The movable part 40 includes a fixed table 400 installed on the upper part of the table surface of the workbench 1. A first driving component 401 is installed on the fixed table 400. A second driving component 402 is installed on the upper part of the first driving component 401. A movable platform 403 is installed on the second driving component 402. A wire feeding plate 404 with a wire feeding groove at the upper end is detachably installed on the movable platform 403.

[0043] Drive component 1 401 and drive component 2 402 are existing linear drive devices such as hydraulic push rods, electric push rods, and electric sliders, and are not limited to one specific device. They are all connected to the control module 2 via electrical signals. In the initial state, drive component 2 402 drives the moving platform 403 to move in front of the alignment plate 53. Then, the wire to be welded is placed in the wire feeding slot 1 on the wire feeding plate 404. The wire feeding plate 404 is supported by the wire feeding slot 1 for a complete section of the wire.

[0044] See Figures 3-5The movable part 40 is connected to a wire end support part 41. The wire end support part 41 includes a positioning frame 410 connected to the movable part 40. A wire pull plate 411 is installed in the positioning frame 410. Two wire release slots 416 are symmetrically opened on the upper end of the wire pull plate 411. The two wire release slots 416 are distributed in a V shape. Two rotating blocks 412 are hinged to the rear end of the wire pull plate 411. A wire release slot 417 for placing the wire end is opened on the upper end of the rotating block 412. The wire end support part 41 also includes a return spring 414 respectively installed on the lower end of the two rotating blocks 412. The lower end of the return spring 414 is fixedly connected to the bottom wall of the positioning frame 410.

[0045] The wire is placed on the wire end support 41. The wire end support 41 moves the wire through the moving part 40. Specifically, in the initial state, the wire feeding plate 404 moves the wire pulling plate 411 and two rotating blocks 412 together through the positioning frame 410. The two rotating blocks 412 are respectively attached to the wire pulling plate 411 through two return springs 414. The wire pulling plate 411 is in a horizontal state. After the wire is placed in the first wire feeding slot, the wire is pushed towards the wire pulling plate 411. The two branch wires on the wire enter the two second wire feeding slots 416 respectively. The two second wire feeding slots 416 separate the two branch wires. Then the wire is pushed, and the wire drives the two branch wires into the third wire feeding slots 417 on the two rotating blocks 412 until the ends of the two branch wires with the insulation removed are in close contact with the alignment plate 53, so as to achieve precise positioning of the wire placement position.

[0046] See Figures 3-5 The moving part 40 is also provided with a clamping part 42 for clamping the end of the wire. The clamping part 42 includes a driving component 3 420 installed on the moving platform 403. A connecting plate 421 is installed on the upper end of the driving component 3 420. A support frame 422 is installed on the lower end of the connecting plate 421 away from the driving component 3 420. Two lifting rods 423 are slidably passed through the support frame 422. A clamping strip 424 is installed on the lower end of the lifting rods 423. A connecting spring 425 is installed between the lower end of the lifting rods 423 and the support frame 422.

[0047] See Figures 1-5 The lower end of the clamping strip 424 is provided with a clamping groove, and the clamping strip 424 is located above the hinge point between the cable tray 411 and the rotating block 412.

[0048] The driving component 3 420 can be any existing linear drive device such as a hydraulic push rod or an electric push rod, and is not limited to any one of them here. It is connected to the control module 2 via an electrical signal. In specific operation, after the ends of the two branch lines of the wire are in close contact with the alignment plate 53, the driving component 3 420 is activated. The driving component 3 420 drives the support frame 422 to move towards the wire pulling plate 411 through the connecting plate 421. The support frame 422 drives the two clamping bars 424 to move towards the wire pulling plate 411 through two lifting rods 423 and two connecting springs 425 until the clamping bars 424 enter the two wire feeding slots 416 respectively. The clamping groove at the lower end of the clamping bar 424 presses against the insulation of the branch line and limits the branch line. At the same time, the clamping bar 424 presses against the corresponding wire pulling plate 411. 11 and rotating block 412 effectively prevent the rotating block 412 from rotating. After the two branch wires of the wire are limited, the second driving component 402 drives the moving platform 403 to move in front of the microphone. The moving platform 403 moves the ends of the two branch wires in the wire to directly above the microphone through the wire feeding plate 404, the wire pulling plate 411 and the two rotating blocks 412. Then, the first driving component 401 is activated, and the first driving component 401 drives the second driving component 402 to descend. The second driving component 402 drives the moving platform 403 to descend. The moving platform 403 moves the ends of the two branch wires in the wire to the upper end of the microphone through the wire feeding plate 404, the wire pulling plate 411 and the two rotating blocks 412. The ends of the two branch wires are located at the two welding positions of the microphone (e.g., Figure 6 (As shown).

[0049] Control module 2 controls the motion controller to move welding module 3 to the upper end of the microphone. Welding module 3 then sequentially welds the ends of the two branch wires to the two welding points on the microphone, thus realizing the microphone welding function (e.g., Figure 7 (As shown).

[0050] The lower end of the rotating block 412 is equipped with an arc-shaped slide rod 413 that slides through the bottom wall of the positioning frame 410. The lower end of the positioning frame 410 is equipped with a force measuring component for measuring the compressive force of the arc-shaped slide rod 413. The force measuring component includes a mounting plate installed at the lower end of the positioning frame 410. The mounting plate is equipped with two pressure sensors 415 that respectively cooperate with the lower ends of the two arc-shaped slide rods 413. The pressure sensors 415 are connected to the control module 2 via electrical signals.

[0051] After the microphone is welded to the ends of the two branch wires of the cable, the placement unit 5 maintains the clamping limit on the microphone. The moving part 40 drives the cable to rise, and the two branch wires in the cable exert pressure on the two rotating blocks 412. The two rotating blocks 412, under pressure, drive the two arc-shaped slide rods 413 to rotate and squeeze the pressure sensor 415 through the ends of the two arc-shaped slide rods 413, thereby detecting the connection strength between the microphone and the cable. At this time, the rotating blocks 412 are in an inclined state (e.g., Figure 8As shown), this effectively prevents relative sliding between the two branch wires inside the wire and the outermost insulating sleeve, further protecting the structural integrity of the wire. Simultaneously, the two rotating blocks 412 compress the two return springs 414. When both branch wires are fully welded to the microphone's solder joints, the pressure measured by the two pressure sensors 415 reaches their rated values. The pressure sensors 415 then transmit the measured data to the control module 2 via electrical signals. The control module 2 processes the data and controls the drive component 510 to operate via electrical signals. The drive component 510 drives the lower pressure plate 511 to rise and reset. The multiple compressed extension springs 504 reset and pass through the corresponding guide blocks 503 and sliding rods 50... 2. The multiple clamping blocks 501 are reset, thereby releasing the limit on the microphone. The first drive unit 401 continues to drive the cable upward through the second drive unit 402, the moving platform 403, the cable feeding plate 404 and the cable end support part 41. At the same time, the cable drives the microphone out of the placement bucket 500. Then the third drive unit 420 drives the support frame 422 to move upward through the connecting plate 421. The support frame 422 drives the two clamping bars 424 to move upward through the two lifting rods 423 and the two connecting springs 425 and releases the limit on the two branches of the cable. Then the welded microphone is removed manually or by the existing robot. Then the welding and connection strength testing steps of the cable and microphone are repeated until all the microphones to be welded are completed.

[0052] If one or both of the two branch wires fail to be fully welded to the microphone, the compressed return spring 414 will drive the rotating block 412 and the arc-shaped slide bar 413 to reset, thereby releasing the pressure on the pressure sensor 415. If the pressure measured by either or both of the two pressure sensors 415 does not reach the rated value, the pressure sensor 415 transmits the measured data to the control module 2 through an electrical signal. The control module 2 processes the data and controls the drive component 401 to work in reverse through an electrical signal, causing the wire to descend again. The control module 2 controls the welding module 3 to re-weld the wire end to the microphone where it failed to be welded. Then, the connection strength between the microphone and the wire is tested again until the requirements are met. Then, the steps of moving and removing the wire and microphone as a whole are repeated, and the welding and connection strength testing steps of the wire and microphone are repeated until all the microphones to be welded are completed, and the welding ends.

[0053] The two rotating blocks 412 can rotate independently via their corresponding return springs 414, thus enabling simultaneous detection of the connection strength between the two branch wires of the cable and the microphone during the same material handling action. Furthermore, the strength detection of the two branch wires is mutually exclusive, accurately detecting the connection strength between any one branch wire and the microphone. This prevents the entire cable and microphone from being connected due to a single branch wire, ensuring a good welding effect. During the connection strength detection process, the connecting spring 425 constantly limits the branch wire via the clamping strip 424, effectively preventing branch wire misalignment. No operator needs to reposition the cable; simply repositioning the cable downwards allows for re-welding of the branch wire end to the microphone, improving the efficiency of secondary welding.

[0054] It is important to note that, compared to existing welding equipment and its weld point inspection methods (such as X-ray and ultrasonic testing), this invention uses conventional mechanical components without any high-cost precision parts. Existing inspection methods can only observe the appearance and internal voids of the weld point, failing to directly verify its actual mechanical connection strength. They cannot address the issue of poorly welded joints that appear normal but are prone to breakage under stress, and are also costly and time-consuming. In contrast, this invention can inspect the welding strength of each branch wire to the microphone head, reducing finished product defects caused by welding flaws at their source, improving the stability and lifespan of microphone products. Furthermore, the tensile strength test of the weld point is a mandatory routine inspection for welding quality control, with clear requirements for the minimum tensile strength of the weld point. This invention complements non-destructive testing in mass production inspection and batch sampling, perfectly meeting the needs of microphone industrial production.
