Description

Technical Field

[0001] The present application relates to the technical field of semiconductor welding, and in particular to a gas guide and a welding device. Background Art

[0002] In order to meet the needs of high-speed fully automatic bonding, the air guide uses a gas guide rail and a non-contact optical fiber detector for guidance and measurement. The air guide mainly uses the principle of air flotation. When the gold wire is transmitted, it passes through the gap between the brake front plate and the brake back plate. At the same time, high-pressure gas enters the gap through the air blow hole of the air flow input pipe to float the gold wire and reduce the contact between the gold wire and the brake front back plate. However, since high-pressure gas will generate a lot of noise when passing through the brake front back plate, the noise near the outlet of the gas guide is measured to be 103.6db, which greatly exceeds the national requirement of less than 80db, causing a certain degree of damage to the hearing of the staff.

[0031] In order to solve the problems in the prior art, the present application provides a gas guide and a welding device, wherein the gas guide can effectively reduce noise, thereby reducing or even avoiding damage to the hearing of workers.

[0032] like Figure 1-6 As shown, an embodiment of the present application provides a gas guide, including a brake 1, an air supply component 2 and an exhaust component 3.

[0033] The brake 1 comprises a conveying groove 11 for the gold wire to pass through and a gas channel 12 communicated with the conveying groove 11 . An end of the gas channel 12 away from the conveying groove 11 is provided with a gas outlet 13 .

[0034] The gas supply assembly 2 includes a gas supply head 21 disposed at the delivery groove 11 and configured to output high-pressure gas into the delivery groove 11 .

[0035] The exhaust assembly 3 includes an exhaust fixture 31 disposed on the brake 1 and an exhaust pipe 32 connected to the exhaust fixture 31 . The exhaust fixture 31 covers the gas outlet 13 so that the gas in the gas channel 12 is discharged through the exhaust pipe 32 .

[0036] In the present application, an exhaust fixture 31 is provided at the air outlet 13 of the brake 1, so that the gas in the gas channel 12 is discharged through the exhaust fixture 31 through the exhaust pipe 32. The exhaust pipe 32 can lead the high-pressure gas to the outside and then discharge it, thereby reducing the noise generated by the high-pressure gas being discharged from the air outlet 13, which can effectively reduce the noise, thereby reducing or even avoiding damage to the hearing of the staff.

[0037] Specifically, the gold wire is transported through the conveying groove 11, and the gold wire is limited. The air supply component 2 is connected to the high-pressure gas source to transport the high-pressure gas into the conveying groove 11, so that the gold wire in the conveying groove 11 floats, reducing the contact between the gold wire and the conveying groove 11 of the brake 1, thereby avoiding wear of the gold wire during transportation.

[0038] In the related art, in the existing gas guide, high-pressure gas enters the conveying groove 11 and then enters the gas channel 12, and is discharged through the gas outlet 13 of the gas channel 12. When the high-pressure gas is discharged from the gas outlet 13, the air pressure instantly decreases, thereby generating a large noise.

[0039] In the embodiment of the present application, an exhaust fixture 31 is provided at the gas outlet 13, and the high-pressure gas enters the exhaust fixture 31 from the gas outlet 13 and is discharged through the exhaust pipe 32. The exhaust pipe 32 can lead the gas output to outside the working environment. For example, the exhaust pipe 32 leads the high-pressure gas to a sewer, a wind room or outdoors, so that the position where the high-pressure gas is instantly depressurized is transferred from the gas guide to outside the working environment, thereby reducing the noise in the working environment.

[0040] In some embodiments, the brake 1 is provided with a first sealing surface 14 , the air outlet 13 is provided on the first sealing surface 14 , and the exhaust fixture 31 is provided with a second sealing surface 311 at one end facing the brake 1 , and the second sealing surface 311 is in contact with the first sealing surface 14 .

[0041] In the present application, the second sealing surface 311 of the exhaust fixture 31 is fitted with the first sealing surface 14 of the brake 1, thereby ensuring the sealing of the connection between the brake 1 and the exhaust fixture 31, and preventing the high-pressure gas in the gas channel 12 from overflowing from the gap between the brake 1 and the exhaust fixture 31. Because the gas in the gas channel 12 has a high air pressure, if it overflows through the gap, it will increase the noise, so it is necessary to ensure the sealing between the brake 1 and the exhaust fixture 31.

[0042] Specifically, in the present application, the exhaust fixture 31 and the brake 1 are sealed through rigid contact.

[0043] Optionally, a sealing member may be provided on the first sealing surface 14 or the second sealing surface 311 , and the sealing of the connection is ensured by the sealing member provided around the air outlet 13 .

[0044] In some embodiments, the first sealing surface 14 includes a first plane 141 and a second plane 142 connected to the first plane 141, a portion of the air outlet 13 is located on the first plane 141, and the other portion is located on the second plane 142; the second sealing surface 311 includes a third plane 3111 and a fourth plane 3112 connected to the third plane 3111, the third plane 3111 abuts the first plane 141, and the fourth plane 3112 abuts the second plane 142.

[0045] In the present application, by setting the first sealing surface 14 to a first plane 141 and a second plane 142, and setting the second sealing surface 311 to a third plane 3111 and a fourth plane 3112, the first plane 141 abuts against the third plane 3111, and the second plane 142 abuts against the fourth plane 3112, the sealing between the brake 1 and the exhaust fixture 31 can be further improved.

[0046] Specifically, an obtuse angle is formed between the first plane 141 and the second plane 142 , and an obtuse angle is formed between the third plane 3111 and the fourth plane 3112 , so as to facilitate the matching installation of the exhaust fixture 31 and the brake 1 .

[0047] In some embodiments, the brake 1 includes a fixed seat 15 and a first plate body 16 and a second plate body 17 arranged on the fixed seat 15. The first plate body 16 and the second plate body 17 are arranged opposite to each other, and a conveying groove 11 and a gas channel 12 are formed between the first plate body 16 and the second plate body 17; the exhaust component 3 also includes a fastener 33, and the exhaust fixture 31 is connected to the fixed seat 15 through the fastener 33.

[0048] In the present application, the first plate 16 and the second plate 17 are fastened by bolts, and the first plate 16 and the second plate 17 are connected to the fixing seat 15 by bolts, so as to ensure that the first plate 16 and the second plate 17 can be effectively fitted, thereby ensuring the sealing of the gas channel 12, and preventing the high-pressure gas from overflowing from the gap between the first plate 16 and the second plate 17 and causing noise. The exhaust fixture 31 is connected to the fixing seat 15 by fasteners 33, which facilitates the assembly and fixation of the exhaust fixture 31 and the brake 1.

[0049] In some embodiments, the fixing seat 15 is provided with a mounting groove 151 and side panels 152 arranged on both sides of the mounting groove 151, and the first plate body 16 and the second plate body 17 are arranged in the mounting groove 151; two fixing grooves 312 are provided at one end of the exhaust fixture 31 facing the fixing seat 15, and the two side panels 152 are respectively plugged into the two fixing grooves 312 and fixed by fasteners 33.

[0050] In the present application, the first plate body 16 and the second plate body 17 are located in the installation groove 151 of the fixed seat 15, and the first plate and the second plate body 17 can be limited in the width direction. The end of the side plate 152 of the fixed seat 15 can be plugged into the fixing groove 312 on the exhaust fixture 31, so as to position the exhaust fixture 31 and ensure the accuracy of the connection between the exhaust fixture 31 and the fixed seat 15, thereby ensuring that the first sealing surface 14 and the second sealing surface 311 can be effectively abutted to ensure the sealing.

[0051] In some embodiments, the two fixing grooves 312 are respectively located on two sides of the second sealing surface 311 .

[0052] In the present application, two fixing grooves 312 are respectively provided on both sides of the second sealing surface 311, so as to form positioning on both sides of the second sealing surface 311, thereby ensuring the positioning effect of the exhaust fixture 31. Specifically, the exhaust fixture 31 is provided with threaded holes at both ends of the two fixing grooves 312, and the fasteners 33 are fixing bolts. The fasteners 33 are threadedly matched with the threaded holes and abut against both sides of the fixing seat 15, thereby completing the fixing of the fixing seat 15 and the exhaust fixture 31.

[0053] In some embodiments, an inserting portion 211 is disposed at one end of the air supply head 21 facing the brake 1 , and the inserting portion 211 is inserted into the conveying groove 11 and fits against the inner wall of the conveying groove 11 .

[0054] In the present application, the cross-section of the conveying groove 11 is a V-shaped structure, and the insertion portion 211 of the brake 1 is inserted into the conveying groove 11 and fits against the inner wall of the conveying groove 11, so that the air supply head 21 and the conveying groove 11 form a channel closed on all sides, with only two ends along the conveying direction of the channel open. The gold wire is conveyed through the channel, which can prevent the high-pressure gas from overflowing from the gap between the air supply head 21 and the conveying groove 11, ensuring that the high-pressure gas can be evenly blown into the conveying groove 11, and there will be no unstable air pressure due to the gap between the air supply head 21 and the conveying groove 11, thereby ensuring the floating effect of the gold wire.

[0055] In some embodiments, the inserting portion 211 is provided with a plurality of gas outlet holes 212 along the conveying direction of the conveying groove 11 , and the plurality of gas outlet holes 212 are arranged opposite to the gas channel 12 .

[0056] In the present application, the high-pressure gas is arranged along the conveying direction of the conveying groove 11 and opposite to the gas channel 12. The ejected high-pressure gas can effectively float the gold wire, ensuring that the gold wire is evenly exposed to the high-pressure gas when passing through the conveying groove 11, thereby ensuring the stability of the gold wire during transportation.

[0057] Specifically, the gas supply head 21 blows high-pressure gas vertically upward, so that the gold wire floats.

[0058] In some embodiments, the air supply head 21 is provided with an air inlet hole connected to the plurality of air outlet holes 212 , and the air supply assembly 2 further includes an air inlet pipe 22 connected to the air inlet hole.

[0059] In the present application, the air inlet pipe 22 is connected to a high-pressure gas source, and the high-pressure gas enters the air inlet hole through the air inlet pipe 22, and then is evenly distributed to the multiple air outlet holes 212 from the air inlet hole and ejected, ensuring the uniformity of the air outlet of the multiple air outlet holes 212.

[0060] The gas guide is provided with an exhaust fixture 31 at the air outlet 13 of the brake 1, so that the gas in the gas channel 12 is discharged through the exhaust fixture 31 through the exhaust pipe 32. The exhaust pipe 32 can lead the high-pressure gas to the outside and then discharge it, thereby reducing the noise generated by the high-pressure gas discharged from the air outlet 13, which can effectively reduce the noise, thereby reducing or even avoiding damage to the hearing of the staff.

[0061] An embodiment of the present application provides a welding device, comprising the above-mentioned gas guide.

[0062] In the present application, the welding device is applied to a ball implanter. By setting an exhaust assembly 3 on the gas guide, the position where the high-pressure gas is released can be transferred from the gas outlet 13 of the gas guide to outside the working environment, thereby reducing the noise in the working environment.
