[0031] 1. This type of ultra-high strength bonding gold wire for optical communication and its wire diameter measuring device feeds the material through the rotation of a turntable and supports the bonding gold wire through an adaptive structure. While preventing the free end of the bonding gold wire from hanging down, it can also effectively avoid deformation of the bonding gold wire.

During the time from straightening to completion of the detection, a new winding wheel can be installed, and the detection can be carried out synchronously, thereby saving detection time and improving detection efficiency. The adaptive structure and the clamp can also prevent the bonding gold wire from shaking, thereby improving the accuracy of the detection result.

[0032] 2. This type of ultra-high strength bonding gold wire for optical communication and its wire diameter measuring device use a supporting airbag to support the bonding gold wire, which can not only prevent the free end of the bonding gold wire from hanging down, which is beneficial for the fixture to smoothly clamp the bonding gold wire, but also effectively prevent the bonding gold wire from deformation. It is also suitable for supporting bonding gold wires of different diameters. The bonding gold wire is released by releasing the gas in the supporting airbag, which can prevent the supporting airbag from rapid wear due to friction.

[0033] 3. This type of ultra-high strength bonding gold wire for optical communication and its wire diameter measuring device can press down on the bonding gold wire to support it through the closed elastic opening and closing parts, which can effectively prevent the free end of the bonding gold wire from hanging down, and the elastic opening and closing parts are also suitable for supporting bonding gold wires of different diameters. In addition, the presence of the connecting belt limits the height of the control rod, which can effectively prevent the control rod from compressing the elastic opening and closing parts and causing deformation of the bonding gold wire.

[0034] 4. This type of ultra-high strength bonding gold wire for optical communication and its wire diameter measuring device, drives the guide screw through the guide motor, adjusts the height of the lifting plate, changes the distance between the upper guide plate and the lower guide plate, and adjusts the annular guide groove to make it suitable for guiding bonding gold wires of different diameters. It is used in conjunction with a straightening wheel that can straighten the bonding gold wire to avoid changes in the detection results due to changes in the position of the bonding gold wire.

[0035] 5. This type of ultra-high strength bonding gold wire for optical communication and its wire diameter measuring device drives the rotating cylinder through the transmission ring cover, and the rotating cylinder drives the self-centering clamp through the mounting ring plate, and then drives the winding wheel fixed by the self-centering clamp to retract and release the bonding gold wire. When used in conjunction with the clamping mechanism, it can not only prevent the bonding gold wire from breaking due to excessive tension, but also can rewind the bonded gold wire that has been tested on the winding wheel.

[0036] 6. This type of ultra-high strength bonding gold wire for optical communication and its wire diameter measuring device utilizes the sliding cooperation of the set positioning protrusion and the positioning slide groove to quickly assemble the mounting bracket on the bearing plate, and drives the fixed pressure plate through the lifter to press the mounting bracket close to the limit bracket to quickly complete the installation of the adaptation part. It is not only convenient to disassemble, but the set T-shaped baffle can block the mounting bracket, which can effectively prevent relative movement between the mounting bracket and the fixed pressure plate due to vibration and other reasons, thereby greatly reducing the probability of the mounting bracket sliding out.

[0050] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0051] Example: Figure 1-4 As shown, the present invention provides an ultra-high strength bonding gold wire for optical communication and a wire diameter measuring device thereof, comprising a bonding gold wire wound on a winding wheel 001, wherein the composition and weight percentage content of the bonding gold wire are as follows: 0.002%-0.004% silver, 0.002%-0.004% copper, 0.0005%-0.0015% germanium, 0.0003%-0.0008% beryllium, and the remainder is gold, and the purity of gold is ≥99.99wt%;

[0052] The wire diameter measuring device used for the wire diameter detection of the above-mentioned bonding gold wire comprises a measuring machine box 1, a turntable 2 arranged above the measuring machine box 1, and a self-centering fixture 6 arranged on the top of the turntable 2 in a circular distribution manner and used to fix the winding wheel 001, and a guide part 3 for guiding the bonding gold wire and straightening the bonding gold wire is provided on one side of the self-centering fixture 6;

[0053] An adapting portion provided on one side of the guide portion 3 for preventing the free end of the bonding wire from falling and deforming, the adapting portion comprising an adapting structure 10 and a mounting bracket 7 for supporting the adapting structure 10, the adapting structure 10 being an adapting component 1 or an adapting component 2;

[0054] A support portion 9 for supporting the adapting portion and adjusting its height;

[0055] Rotate a rotating assembly 23 disposed on the turntable 2 for supporting the self-centering fixture 6;

[0056] A diameter measuring component 4 for detecting the diameter of the bonding gold wire is arranged on the top of the measuring chassis 1;

[0057] A control mechanism 8 disposed on one side of the diameter measuring assembly 4 for driving the rotating assembly 23 and the turntable 2;

[0058] A clamping mechanism 5 capable of driving the bonding gold wire is arranged on the other side of the diameter measuring assembly 4 .

[0059] Specifically, the clamping mechanism 5 is composed of a clamp for clamping the bonding gold wire, a moving component for driving the clamp, and a visual detection sensor for detecting the bonding gold wire. The clamp can adopt a pneumatic control structure, an electric control structure, or other clamping structure that can clamp the bonding gold wire. The clamp can also be a structure that can fix the winding wheel 001 and drive its rotation. In cooperation with the rotating component 23, different positions on the bonding gold wire can be detected to achieve uniformity detection; the visual detection sensor can be set at a position where the bonding gold wire can be detected, and its specific structure and installation position are not limited here; the moving component is installed in the measuring chassis 1, and can be a multi-stage telescopic rod.

[0060] Among them, Figure 4-6 and Figure 8 As shown, the support part 9 includes an adjustment component, a gantry 93 for supporting the adjustment component, and a fixing component 92 for fixing the adapting part. The adjustment component includes an adjustment screw 96 rotatably arranged on a horizontal plate of the gantry 93 and an adjustment plate 91 connected to a nut slide outside the adjustment screw 96. A distance sensor 94 is arranged at the bottom of the adjustment plate 91. The gantry 93 is installed on the top of the guide bracket 37.

[0061] The fixing assembly 92 includes a carrying plate 921 installed on the bottom of the adjustment plate 91, a limiting bracket 922 installed on the top of the carrying plate 921, and two fixed pressure plates 924 that slide with the limiting holes on the limiting bracket 922 to improve the stability of the fixed pressure plate 924 when moving. A positioning groove 925 is provided on the carrying plate 921, and a lifter 923 is provided on one side of the limiting bracket 922. The moving body of the lifter 923 is connected to the fixed pressure plate 924 via a connecting plate, and a T-shaped baffle 9241 matching the positioning groove 925 is provided at one end of the fixed pressure plate 924.

[0062] Specifically, the adjustment component also includes an adjustment motor 95 arranged at the bottom of the adjustment plate 91. The output shaft of the adjustment motor 95 is connected to the adjustment screw 96. The adjustment motor 95 drives the adjustment screw 96, so that the adjustment plate 91 drives the distance measuring sensor 94 and the fixed component 92 to move, and finally changes the height of the adaptation part. The distance from the adjustment plate 91 to the gantry 93 is detected by the distance measuring sensor 94, so as to facilitate the control of the height of the adaptation part.

[0063] The connecting plate is controlled to move downward with the fixed pressure plate 924 through the lifter 923, and the mounting bracket 7 close to the side of the limiting bracket 922 is pressed by the fixed pressure plate 924 to complete the installation operation of the adaptation part. The T-shaped baffle plate 9241 provided can block the mounting bracket 7, which can effectively prevent relative movement between the mounting bracket 7 and the fixed pressure plate 924 due to vibration and the like, thereby greatly reducing the probability of the mounting bracket 7 sliding out.

[0064] Among them, Figure 5 and Figure 8 As shown, a mounting through hole 71 is provided at the center position of the top plate of the mounting bracket 7, and a positioning protrusion 72 that slides with the positioning groove 925 is provided at the bottom of the top plate of the mounting bracket 7. By utilizing the sliding cooperation between the positioning protrusion 72 and the positioning groove 925, the mounting bracket 7 can be quickly assembled on the supporting plate 921.

[0065] Embodiment 1, as Figure 4 As shown, the adaptation component 1 is composed of a connecting substrate 101 installed at the bottom of the mounting bracket 7 and a supporting airbag 102 for supporting the bonding gold wire. A notch is formed at the bottom of the supporting airbag 102 for allowing the bonding gold wire to pass through. An air duct connected to the supporting airbag 102 is provided at the top of the connecting substrate 101. The air duct can pass through the mounting through hole 71. The air duct is connected to the air supply path via a three-way valve. The inflation and deflation of the supporting airbag 102 is controlled by switching the three-way valve. This is one embodiment, and other embodiments may also be used.

[0066] Pass the bonding gold wire through the gap, and then switch the three-way valve to inflate the supporting airbag 102. The bonding gold wire collides with the air-filled supporting airbag 102. The supporting airbag 102 is used to support the bonding gold wire. This can not only prevent the free end of the bonding gold wire from falling, which is beneficial for the fixture to smoothly clamp the bonding gold wire, but also effectively prevent the bonding gold wire from deforming. It is also suitable for supporting bonding gold wires of different diameters. Before the clamping mechanism 5 pulls the bonding gold wire, the gas in the supporting airbag 102 is released (not all of it may be released), and the bonding gold wire is released to prevent the supporting airbag 102 from rapid wear due to friction. During the detection process, the inflated supporting airbag 102 is used to support the bonding gold wire, and the fixture is used to prevent the bonding gold wire from shaking, thereby improving the accuracy of the detection result.

[0067] Embodiment 2, as Fig. 9 and Fig.10 As shown, the adaptation component 2 includes an elastic opening and closing member 108 installed at the bottom of the mounting bracket 7 via a support seat 109 and a control rod 103 that slidably cooperates with the mounting through hole 71, and a control handle 105 and a connecting belt 107 are respectively provided at both ends of the control rod 103, a limit plate 106 is sleeved at the lower part of the control rod 103, and a return spring 104 is also sleeved outside the control rod 103, and both ends of the return spring 104 are respectively connected to the limit plate 106 and the top plate of the mounting bracket 7;

[0068] The top of the elastic opening and closing piece 108 is provided with a hanging ear 1082 for connecting to the connecting belt 107. The middle part of the elastic opening and closing piece 108 is bent to form an arc groove 1081 that can fit with the surface of the bonding wire. The connecting belt 107 is made of a material with good flexibility and not easy to break, such as rubber. The elastic opening and closing piece 108 is made of stainless steel, copper, titanium, nickel-chromium alloy and other materials.

[0069] The support seat 109 is provided with an installation groove 1091 for installing the elastic opening and closing member 108, and the bottom of the support seat 109 is screwed with a locking bolt 1092 for locking the elastic opening and closing member 108. By loosening the locking bolt 1092, the elastic opening and closing member 108 can be removed, which is convenient for replacing the elastic opening and closing member 108 later.

[0070] Pull the control handle 105 upwards, so that the control rod 103 moves upwards with the limit plate 106 and squeezes the reset spring 104. The upward moving control rod 103 drives the connecting belt 107 to open the elastic opening and closing piece 108, and then the bonding wire passes through the arc groove 1081. Then, release the control handle 105. When the control rod 103 moves downwards due to the elastic force, the closed elastic opening and closing piece 108 can press the bonding wire to support it, which can effectively prevent the free end of the bonding wire from falling, and the elastic opening and closing piece 108 is also suitable for supporting bonding wires of different diameters. In addition, the existence of the connecting belt 107 limits the height of the control rod 103, which can effectively prevent the control rod 103 from compressing the elastic opening and closing piece 108 and causing deformation of the bonding wire.

[0071] Among them, Figure 4-7 As shown, the guide part 3 includes a guide bracket 37 installed at the edge of the turntable 2, a guide wheel assembly 31 rotatably arranged on the guide bracket 37, a guide motor 32 installed on the top of the guide bracket 37, and a straightening wheel 34 that can allow the bonding gold wire to pass through. A straightening seat 35 is provided on the top plate of the guide bracket 37, and a movable groove 351 for installing the straightening wheel 34 is opened on the straightening seat 35. A lifting plate 33 is provided on the inner side of the guide bracket 37, and a guide screw 36 is also rotatably arranged on the top plate. The upper end of the guide screw 36 is connected to the output shaft of the guide motor 32, and the lifting plate 33 is connected to a nut slide seat sleeved outside the guide screw 36.

[0072] The guide wheel assembly 31 includes a lower guide plate 313 rotatably connected to the guide bracket 37 via a rotating sleeve 314 and an adjustment sleeve 312 slidably arranged in the rotating sleeve 314. One end of the adjustment sleeve 312 is provided with an upper guide plate 311, and the other end is connected to the lifting plate 33. An annular guide groove for guiding the bonding gold wire is formed between the upper guide plate 311 and the lower guide plate 313.

[0073] After the guide motor 32 is started, it drives the guide screw 36 to adjust the height of the lifting plate 33, changes the distance between the upper guide plate 311 and the lower guide plate 313, and adjusts the annular guide groove to make it suitable for guiding bonding wires of different diameters.

[0074] Specifically, a straightening hole is provided on the straightening wheel 34, and the bonding gold wire can be straightened by passing through the straightening hole, thereby preventing the bonding gold wire in a bent state from affecting the detection result.

[0075] Among them, Fig.11As shown, the rotating assembly 23 includes a rotating cylinder 231 rotatably connected to the turntable 2 and a transmission ring cover 233 installed at one end of the rotating cylinder 231, a limiting ring 235 for limiting is provided on the outer wall of the rotating cylinder 231, a mounting ring plate 232 for installing a self-centering fixture 6 is provided at the other end of the rotating cylinder 231, and a transmission tooth 234 distributed in a ring shape is provided on the outer wall of one end of the transmission ring cover 233.

[0076] The transmission ring cover 233 drives the rotating cylinder 231, and the rotating cylinder 231 drives the self-centering clamp 6 through the mounting ring plate 232, and then drives the winding wheel 001 fixed by the self-centering clamp 6 to retract and release the bonding gold wire. When used in conjunction with the clamping mechanism 5, it can not only prevent the bonding gold wire from breaking due to excessive tension, but also can rewind the bonded gold wire that has been tested onto the winding wheel 001.

[0077] Among them, such as 2 and Figure 3 As shown, the control mechanism 8 includes a control motor 81, a sector gear 82 that can mesh with the transmission teeth 234, a switching component 84, and a motor bracket installed on the top of the measuring chassis 1 for supporting the control motor 81. A transmission shaft 83 whose lower end is rotatably connected to the motor bracket is provided in the mounting hole of the sector gear 82. The transmission shaft 83 is driven by the switching component 84, and the switching component 84 drives the transmission shaft 83 to rotate the sector gear 82, and the transmission ring cover 233 is driven by the meshing transmission between the sector gear 82 and the transmission teeth 234.

[0078] Specifically, the switching assembly 84 consists of a switch, a gear 1 sleeved and fixed on the outside of the transmission shaft 83, and two gears 2 respectively meshing with the transmission ring gear 22 and gear 1. The two movable ends of the switch are connected to a switching bracket. The mounting hole of gear 2 is provided with an axis rod rotatably connected to the switching bracket. The switch can be a double cylinder, and the movement of the switching bracket is controlled by the switch. When one of the gears 2 is meshed with the transmission ring gear 22, the other gear 2 is disengaged from the gear 1, thereby realizing separate control of the transmission shaft 83 and the support column 21.

[0079] Among them, Figure 3 As shown, a support column 21 rotatably connected to the measuring machine case 1 is provided at the bottom center of the turntable 2, and a transmission gear ring 22 driven by a switching component 84 is sleeved on the outer wall of the support column 21. The transmission gear ring 22 is driven by the switching component 84, so that the support column 21 drives the turntable 2 to rotate for intermittent loading.

[0080] Among them, Figure 1-3As shown, the diameter measuring assembly 4 includes a laser diameter measurer 41 and a supporting bracket 43 for supporting the laser diameter measurer 41. A height adjuster 42 for adjusting the height of the supporting bracket 43 is symmetrically provided at the bottom of the supporting bracket 43. The height of the laser diameter measurer 41 is adjusted by the height adjuster 42, and the laser diameter measurer 41 is adjusted to the lowest point to prevent the clamping mechanism 5 from being detected and causing an error in the detection result. After the clamping mechanism 5 pulls the bonding gold wire to a suitable position, the height adjuster 42 drives the laser diameter measurer 41 back to its original position, and the bonding gold wire is scanned by laser to complete the wire diameter measurement.

[0081] During operation, after the free end of the bonding gold wire is pulled out, the winding wheel 001 wound with the bonding gold wire is placed outside the clamping jaws of the self-centering clamp 6, and the winding wheel 001 is fixed by the clamping jaws moving outward. After the bonding gold wire is passed around the guide wheel assembly 31, it is passed through the straightening wheel 34, and then the straightening wheel 34 is placed in the movable groove 351. Then, the bonding gold wire is supported by the adaptive structure 10, and the transmission gear ring 22 is driven by the switching assembly 84, so that the supporting column 21 drives the turntable 2 to rotate. After the winding wheel 001 reaches the detection station, the turntable 2 stops rotating. After the laser diameter gauge 41 is adjusted to the lowest point by the height adjuster 42, the moving assembly of the clamping mechanism 5 drives the clamp close to the bonding gold wire. After the clamp clamps the bonding gold wire, it is driven by the switching assembly 84. The transmission shaft 83 rotates the sector gear 82, and the transmission ring cover 233 is driven by the meshing transmission of the sector gear 82 and the transmission teeth 234. The rotating component 23 drives the winding wheel 001 with the help of the self-centering clamp 6, and cooperates with the moving component to straighten the bonding gold wire. Then the height adjuster 42 drives the laser diameter gauge 41 back to the original position, and uses the laser to scan the bonding gold wire to complete the wire diameter measurement. After the inspection is completed, the bonding gold wire that has been inspected is rewound on the winding wheel 001 through the cooperation of the clamping mechanism 5, the rotating component 23 and the control mechanism 8. During the time when the turntable 2 stops and rotates to complete the inspection, the worker will remove the winding wheel 001 wound with the bonding gold wire that has been inspected, and put on the winding wheel 001 wound with the bonding gold wire that has not been inspected.
