Description

Technical Field

[0001] The invention relates to the technical field of LED wire bonding machines, in particular to an LED wire bonding machine. Background Art

[0002] LED wire bonder is a key semiconductor device that connects chip pads and package pins with metal wires. The fundamental feature of the wire bonder's working process is that it guides the metal wires to make complex and high-speed movements in three-dimensional space to form various special wire arc shapes that meet the requirements of different packaging forms.

[0003] When the LED wire bonding machine is working, the operator first places the LED chip to be welded accurately on the workbench of the wire bonding machine and fixes the position. The operator fixes the LED chip, and drives the welding head through multi-dimensional positioning and fine-tuning of the mobile robotic arm. With the help of ball screws, linear guides and stepper motors, it fine-tunes in multi-axis directions according to the preset program. With the help of machine vision, it can accurately align the chip welding point, and the welding head approaches the welding position, and the welding head descends to complete the welding.

[0004] In the production and manufacturing process of LED chips, welding is a crucial link. However, LED chips are usually made of semiconductor materials. The metal electrodes on their surface can easily react chemically with oxygen in the air during the welding process, leading to oxidation. Once oxidation occurs, an oxide film will form on the surface of the chip. This oxide film will not only increase the welding resistance, resulting in poor current transmission and affecting the luminous efficiency and stability of the LED chip, but also easily lead to a reduction in the mechanical strength of the welding point. In the subsequent use process, the welding point is prone to loosening, falling off and other problems, which greatly shortens the service life of the LED product. The existing LED wire welding machine still has certain limitations during use. Summary of the invention

[0005] The purpose of the present invention is to provide an LED wire bonding machine to solve the problem mentioned in the above background technology that LED chips are usually made of semiconductor materials, and the metal electrodes on their surfaces are very likely to chemically react with oxygen in the air during the welding process, resulting in oxidation. Once oxidation occurs, a layer of oxide film will form on the surface of the chip. This oxide film will not only increase the welding resistance, resulting in poor current transmission, affecting the luminous efficiency and stability of the LED chip, but may also lead to a reduction in the mechanical strength of the welding point.

A fixed ring 6 is fixedly installed through the outside of the welding torch head 3 near the top of the protective cover 5. A trigger component is provided on one side of the fixed ring 6. A positioning bracket 19 is fixedly installed on the outside of the top side of the protective cover 5. An adsorption component and a cleaning component are provided on the bottom side of the positioning bracket 19.

[0031] The protective cover 5 is set to be semi-circular in a top view, and a flexible rubber ring 9 is adhesively fixed to the outer surface edge of the bottom end of the protective cover 5.

[0032] Specifically, the protective cover 5 is semi-circular so that the discharged inert gas can be more concentrated and discharged more evenly. At the same time, through the setting of the flexible rubber ring 9 at the bottom of the protective cover 5, when the protective cover 5 drives the flexible rubber ring 9 to fit with the surface of the LED chip, a flexible contact is formed, avoiding hard contact damage.

[0033] The anti-oxidation component includes a plurality of exhaust heads 10 and a fixed conduit 13. The plurality of exhaust heads 10 are installed in the inner side of the bottom end of the protective cover 5 at equal angles and penetrate around it. The fixed conduit 13 is fixedly installed through the bottom end of the gas storage tank 4. A guiding pipe 11 is connected and arranged in a conducting manner between the intake ends of the plurality of exhaust heads 10.

[0034] One side of the top end of the guiding pipe 11 is fixedly installed with a stretching pipe 12 through it. The input end of the stretching pipe 12 is connected to the output end of the fixed conduit 13. One side of the outer part of the fixed conduit 13 is fixedly installed with a fixing bracket 14 through it. One end of the fixing bracket 14 is fixedly installed on the outer side of one side of the welding torch head 3. An opening and closing component is arranged inside one side of the fixed conduit 13.

[0035] The opening and closing component includes a rotating shaft 17 and a sealing plate 18. The rotating shaft 17 is rotatably installed through the inner side of one side of the fixed conduit 13. The sealing plate 18 is fixedly installed on the outer side of the rotating shaft 17 inside the fixed conduit 13. A limiting gear 16 is fixedly installed on the penetrating end of one side of the rotating shaft 17.

[0036] The triggering component includes a plurality of guiding rods 7 and a first limiting rack 15. The plurality of guiding rods 7 are fixedly installed at equal angles around the outer side of the top end of the protective cover 5. One end of each of the plurality of guiding rods 7 is slidably installed through the top end of the fixed ring 6. The first limiting rack 15 is longitudinally fixedly installed on the outer side of the top end of one of the guiding rods 7. One side of the first limiting rack 15 is meshed with one side of the limiting gear 16. Compression springs 8 are sleeved through the outer sides of the plurality of guiding rods 7. Two ends of each compression spring 8 are respectively installed on one side of the fixed ring 6 and the protective cover 5. One side of the first limiting rack 15 is meshed with one side of the limiting gear 16.

[0037] In the present embodiment, when welding the LED chip, the operator first places the LED chip to be welded accurately on the workbench of the wire welding machine and fixes the position. The operator fixes the LED chip, and drives the welding gun head 3 to move through the mobile mechanical arm 1 formed by the existing mechanism, accurately aligns with the chip welding point, and the welding gun head 3 approaches the welding position. The welding gun head 3 descends to start welding, and the welding gun head 3 drives the protective cover 5 to descend. When the protective cover 5 descends to a certain position, the flexible rubber ring 9 at the bottom of the protective cover 5 contacts the surface of the LED chip, and then the welding gun head 3 continues to descend. At this time, the protective cover 5 is resisted by the LED chip and no longer moves downward. As the welding gun head 3 continues to descend, the gas storage tank 4, the fixing ring 6, the fixing conduit 13 and the limit gear 16 continue to descend. During the descent, the limit gear 16 rotates outside the meshing limit rack 15 on one side, and the rotation of the limit gear 16 drives the inside of the fixed conduit 13 on one side. The rotating shaft 17 and the sealing plate 18 rotate, so that the fixed conduit 13 is connected with the guide tube 11 and the stretching tube 12, so that the gas stored in the gas tank 4 in advance is introduced into the several exhaust heads 10, and then evenly discharged, so that a small inert gas protection gas curtain is integrated near the welding head of the welding gun head 3, which effectively prevents the LED chip and the welding wire from oxidizing at the moment of welding, and improves the reliability of welding. At the same time, after the welding is completed, the welding gun head 3 is lifted and detached. During the lifting process, the welding gun head 3 will drive the gas tank 4, the fixing ring 6, the fixed conduit 13 and the limit gear 16 to be lifted synchronously. At this time, the limit gear 16 performs reverse reset rotation outside the limit rack 15 meshing on one side. Through the reverse reset rotation of the limit gear 16, the rotating shaft 17 and the sealing plate 18 will synchronously perform reverse reset rotation, thereby isolating and sealing the fixed conduit 13 and the stretching tube 12, thereby stopping the gas discharge, so that the whole can automatically start and close the operation.

[0038] It should also be noted that when the welding gun head 3 drives the fixed ring 6 to descend, the fixed ring 6 will squeeze the compression spring 8 mounted on the outside of the guide rod 7, causing the compression spring 8 to be compressed. At the same time, in the process of the welding gun head 3 driving the fixed ring 6 to lift, the top of the compression spring 8 mounted on the outside of the guide rod 7 will slowly lose the squeezing force, causing the compression spring 8 to rebound and reset synchronously. Through the compression and rebound characteristics of the compression spring 8, it is ensured that after the welding gun head 3 is lifted and reset as a whole after welding, the relevant components can also return to their original positions, preparing for the next working cycle, thereby maintaining the periodic and stable operation of the entire device.

[0039] Example 2: Please refer to Figure 6 - Figure 9This embodiment further explains Example 1. The adsorption component includes a limit rack 20 and an electrostatic adsorption plate 30. The limit rack 20 is longitudinally fixedly installed on the outside of one side of the bottom end of the fixing ring 6. The electrostatic adsorption plate 30 is fixedly installed on the inside of one side of the positioning frame 19. The positioning frame 19 is located at both ends of the electrostatic adsorption plate 30 and is respectively rotatably penetrated by a transmission shaft 1 21 and a transmission shaft 2 22. The transmission shaft 1 21 and the transmission shaft 2 22 are externally sleeved with an ultra-thin transmission sheet 23 for fitting transmission.

[0040] A limiting toothed ring 24 is externally embedded and rotatably mounted on one side of the positioning frame 19 close to the transmission shaft 1 21. One side of the limiting toothed ring 24 is meshedly connected with one side of the limiting rack 20. A plurality of abutment grooves 25 are embedded and arranged around the inner wall of the limiting toothed ring 24. The limiting toothed ring 24 and the axis of the transmission shaft 1 21 are on the same center line.

[0041] A positioning plate 26 is fixedly installed at one end of the transmission shaft 21 close to the abutment groove 25, a positioning shaft 28 is fixedly installed at one side edge of the positioning plate 26, a retaining tooth 27 is rotatably installed outside the positioning shaft 28, one side of the retaining tooth 27 is placed in abutment inside one of the abutment grooves 25, and a spring sheet 29 is installed in abutment between one side of the retaining tooth 27 and one side of the positioning plate 26.

[0042] The cleaning assembly includes a collecting box 31 and a fixing rod 32. The collecting box 31 is arranged on the outside of the side of the ultra-thin transmission sheet 23 away from the protective cover 5. One end of the fixing rod 32 is fixedly installed on the outside of the side of the collecting box 31, and the other end of the fixing rod 32 is fixedly installed on the outside of the side of the positioning frame 19. A through groove 33 is penetrated inside the side of the collecting box 31 close to the ultra-thin transmission sheet 23. A scraper 34 is fixedly installed on the inner wall of one side of the collecting box 31. One side of the scraper 34 is in contact with the outer surface of one side of the ultra-thin transmission sheet 23. A collecting port 35 is penetrated on the bottom side of the collecting box 31.

[0043] In this embodiment, when several exhaust heads 10 start to exhaust, the dust generated during the welding process is driven by the inert gas to reach one side of the electrostatic adsorption plate 30. These electrostatic adsorption plates 30 are connected to an existing high-voltage electrostatic generator. When the generator is powered on, the electrostatic adsorption plate 30 will carry a high voltage to form a strong electrostatic field. Through the ultra-thin transmission sheet 23, the dust is adsorbed on the surface of the ultra-thin transmission sheet 23, thereby preventing the dust generated during the welding process from falling on the LED chip or welding wire, causing problems such as cold welding and short circuit. At the same time, it can ensure that the welding environment inside the protective cover 5 is clean, effectively avoiding welding defects caused by dust pollution, and improving product yield.

[0044] It should also be noted that during use, when the welding gun head 3 is lowered, it will drive the limiting rack 20 on one side to descend synchronously, thereby driving the limiting toothed ring 24 on one side to rotate. At this time, the limiting toothed ring 24 will not drive the blocking teeth 27 and the positioning plate 26 on one side to rotate with the transmission shaft 1 21. When the welding gun head 3 is lifted after welding, it will drive the limiting rack 20 on one side to be lifted synchronously, thereby driving the limiting toothed ring 24 on one side to rotate in the opposite direction. At this time, the limiting toothed ring 24 will drive the blocking teeth 27 and the positioning plate 26 on one side to rotate with the transmission shaft 1 21. The positioning plate 26 rotates with the transmission shaft 1 21, and is transmitted through the sleeve wrapping of the transmission shaft 1 21, the transmission shaft 22 and the ultra-thin transmission sheet 23, so that when the ultra-thin transmission sheet 23 rotates, the ultra-thin transmission sheet 23 surface with dust adsorbed on the bottom is transmitted to the opening of the through groove 33 on one side of the collection box 31, and then the scraper 34 at the opening of the through groove 33 is fitted to scrape off the dust debris and collect it into the collection box 31. At a later stage, the collection port 35 on one side of the collection box 31 can also be opened to facilitate dust cleaning.

[0045] It should also be noted that, through the installation and cooperation of a number of abutment grooves 25, positioning plates 26, positioning shafts 28, retaining teeth 27 and spring sheets 29, the limiting gear ring 24 can only drive the transmission shaft 21 to rotate in one direction, ensuring that the dust adsorbed on the surface of the ultra-thin transmission sheet 23 during the transmission process can be scraped off by the scraper 34 into the collection box 31.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
