Description

Technical Field

[0001] The present invention belongs to the field of LED packaging, and specifically relates to a ceramic annular air blowing device for a wire bonding machine in an LED packaging process. Background Art

[0002] The wire bonding machine in the LED packaging process is an indispensable part of the LED packaging process. Its main function is to connect the LED chip and the pins by welding metal wires to achieve electrical connection. The air blowing nozzle for the wire bonding machine in the LED packaging process is a key component in the wire bonding machine equipment, mainly used to provide precise air flow control during the wire bonding process to assist the wire bonding operation and improve the welding quality and efficiency.

[0003] Most of the existing air blowing devices have a hollow annular structure and are made of plastic. The plastic air blowing device has a relatively light weight. Under the action of high temperature, the material is prone to hardening and cracking and deformation. Moreover, due to the design defect of the internal structure, the waste of nitrogen and hydrogen is relatively serious. At the same time, under the use of the existing air blowing device, the copper wire is prone to oxidation. When welding the copper wire, first, the copper wire needs to be melted into a ball. During the process of melting into a ball, the high temperature generated will quickly oxidize the copper wire to form copper oxide. The bonding degree of copper oxide with gold or aluminum on the LED electrode is poor, and there will be a bad situation of open circuit and dead lamp in the later application. Because the copper wire is relatively hard, during the welding process, the ultrasonic wave output from the welding head is transmitted to the ceramic nozzle, which will cause the ceramic nozzle to vibrate. During the pressing process, due to the vibration, the ceramic nozzle cannot press the copper wire well, resulting in bad situations such as asymmetric solder joints and poor bonding. Summary of the Invention

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figures 1 to 7 shown:

[0026] Embodiment 1: The present invention provides a ceramic annular blowing device for an LED packaging process wire bonding machine, including: a blowing frame mechanism 1, including a blowing frame component 11, and a positioning frame component 12 arranged on one side of the blowing frame component 11; a connecting rod mechanism 2, including a connecting rod component 21, a group of positioning components 22 symmetrically installed inside the connecting rod component 21, an unlocking component 23 arranged on one side of the connecting rod component 21, and an ejecting component 24 arranged on the other side of the connecting rod component 21; the connecting rod component 21 can be slidably clamped inside the positioning frame component 12, and the positioning component 22 can position the connecting rod component 21; the blowing frame component 11 includes a blowing frame body 111, and a through hole 112 is opened on the blowing frame body 111; the entire blowing frame mechanism 1 is made of ceramic material, and the through hole 112 adopts a circular structure;

[0027] Among them, the air-blowing frame mechanism 1 is made of ceramic material and the through-hole 112 adopts a circular structure, which can effectively prevent deformation, is not easy to break, has high temperature resistance, and under non-external force, its service life is infinitely extended; the internal structure is optimized, and the consumption of nitrogen and hydrogen is one-third of that of plastic annular air-blowing, reducing the cost of LED packaging process; when the air-blowing frame mechanism 1 needs to be replaced, by pressing the unlocking component 23, a set of positioning components 22 can be retracted into the connecting rod component 21, and at the same time, the ejecting component 24 will push the positioning frame component 12 to separate the air-blowing frame mechanism 1 from the connecting rod mechanism 2. After replacing the air-blowing frame mechanism 1, when the new positioning frame component 12 is forcefully inserted into the connecting rod component 21, the positioning component 22 will limit the positioning frame component 12, so as to achieve the effect of fixed connection, and at the same time, the ejecting component 24 is compressed.

[0028] Specifically, the positioning frame component 12 includes a positioning frame body 121, and trapezoidal card slots 122 are symmetrically arranged inside the positioning frame body 121.

[0029] Specifically, the connecting rod component 21 includes a connecting rod body 211, one end of the outer side of the connecting rod body 211 is fixedly connected with a positioning rod 212, and a positioning hole 213 is also arranged on the positioning rod 212.

[0030] Specifically, the positioning component 22 includes a positioning block 221 and a first spring 222, and a first inclined surface 223 is also arranged on the outer side of the positioning block 221.

[0031] Specifically, the positioning block 221 is limited and embedded inside the connecting rod body 211, and the first spring 222 can drive the first inclined surface 223 on the positioning block 221 to partially extend out of the connecting rod body 211.

[0032] Specifically, a second inclined surface 224 is also arranged on the outer side of the positioning block 221.

[0033] Specifically, the unlocking component 23 includes a first round rod 231 and a second spring 232, one end of the first round rod 231 is fixedly connected with a U-shaped frame 233, the other end of the first round rod 231 is fixedly connected with a pressing ring 234, and a limiting ring 235 is fixedly connected to the outer side of the first round rod 231.

[0034] Specifically, the first round rod 231 is limited and slidably embedded inside the connecting rod body 211, the second spring 232 drives the limiting ring 235 to move away from the positioning block 221, and the U-shaped frame 233 can drive the second inclined surface 224 to drive a set of positioning blocks 221 to approach each other and compress the first spring 222 inside the connecting rod body 211.

[0035] As can be seen from the above, when the air blowing frame mechanism 1 needs to be replaced, pushing the pressing ring 234 can cause the first round rod 231 to drive the U-shaped frame 233 to move, and the second spring 232 is compressed by the limiting ring 235 inside the connecting rod body 211. When the U-shaped frame 233 moves, it will abut against the second inclined surface 224 and cause a set of positioning blocks 221 to approach each other. When a set of positioning blocks 221 approach each other, they will disengage from the trapezoidal card slot 122. At this time, the staff can easily separate the air blowing frame mechanism 1 from the connecting rod mechanism 2. At the same time, when a set of positioning blocks 221 approach each other, the first spring 222 will also be compressed inside the connecting rod body 211. After releasing the pressing ring 234, the reset of the second spring 232 will cause the limiting ring 235 to drive the first round rod 231 to move. The movement of the first round rod 231 will cause the U-shaped frame 233 to move away from a set of positioning blocks 221. At this time, a set of positioning blocks 221 will also move away from each other under the drive of the first spring 222 and thus extend out of the connecting rod body 211. Slide and snap the positioning frame body 121 on the new air blowing frame mechanism 1 outside the connecting rod body 211. When the edge of the positioning frame body 121 abuts against the first inclined surface 223 on a set of positioning blocks 221, a set of positioning blocks 221 will be received inside the connecting rod body 211 and the first spring 222 will be compressed. When the positioning frame body 121 is completely sleeved outside the connecting rod body 211, the reset of the first spring 222 will cause a set of positioning blocks 221 to be pushed and embedded into the trapezoidal card slot 122. At this time, the positioning frame body 121 will be fixed outside the connecting rod body 211 for convenient use.

[0036] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the ejection assembly 24 includes a second round rod 241 and a third spring 242. One end of the second round rod 241 is fixedly connected to a short column 243, and the other end of the second round rod 241 is fixedly connected to a push ring 244.

[0037] Specifically, the third spring 242 is fixedly connected to one side of the short column 243. The short column 243 and the third spring 242 are both limited and snap-fitted inside the connecting rod body 211. The third spring 242 drives the short column 243 to drive the second round rod 241 and the push ring 244 to extend out of the connecting rod body 211.

[0038] As can be seen from the above, when the positioning frame body 121 is slid and snap-fitted outside the connecting rod body 211, the push ring 244 will be pushed, so that the second round rod 241 drives the short column 243 to move and the third spring 242 is compressed inside the connecting rod body 211. When a set of positioning blocks 221 approach each other and disengage from the trapezoidal card slot 122, the reset of the third spring 242 will cause the short column 243 and the second round rod 241 to move and drive the push ring 244 to push the positioning frame body 121, so that the air blowing frame mechanism 1 can be quickly separated from the connecting rod mechanism 2, facilitating the staff to replace it.
