Description

Technical Field

[0001] This utility model relates to the field of semiconductor processing auxiliary equipment technology, and in particular to a sealed track clamp for a gold-copper alloy wire bonding machine. Background Technology

[0002] A copper alloy wire bonding machine is a device used to weld copper alloy wire to the surface of other media. Its working principle mainly involves the supply, melting, and connection of the copper alloy wire to the metal being welded. During the welding process, the wire bonding machine first continuously supplies copper alloy wire through a specific supply mechanism, such as a filter or a motor-driven gear transmission mechanism. These mechanisms provide pulse signals to the coil circuit through the output pins of the motion control board, thereby precisely controlling the wire feeding speed and length. Subsequently, the wire bonding machine uses an electric arc to heat the copper alloy wire, melting it. This melting process requires precise control of temperature and time to ensure that the copper alloy wire melts uniformly and forms a good bond with the metal being welded.

[0003] The frames used in copper alloy wire bonding machines are prone to reacting with air due to increasing production requirements. Existing gold-copper alloy wire bonding machines lack anti-oxidation devices, affecting the quality of the formed products. Therefore, it is particularly important to design a sealed track clamp for gold-copper alloy wire bonding machines to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the frames used in copper alloy wire bonding machines are prone to reacting with air as production requirements increase. Existing gold-copper alloy wire bonding machines do not have anti-oxidation devices, which affects the quality of the formed products. Therefore, a sealed track clamp for a gold-copper alloy wire bonding machine is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sealed track clamp for a gold-copper alloy wire bonding machine, comprising a heating block and a pressure plate, wherein the heating block and the pressure plate cooperate with each other, and the heating block and the pressure plate are separately installed on corresponding external equipment. The pressure plate is provided with an air inlet, which is connected to an external nitrogen-hydrogen mixed gas pipe. The heating block is evenly distributed with multiple sets of bowl-shaped gas storage grooves and multiple sets of heating block gas passage holes.

[0006] Preferably, the pressure plate is provided with air blowing holes, which are connected to multiple sets of air passage holes of the heating block.

[0007] Preferably, the left side of the pressure plate is provided with a left air inlet and the right side of the pressure plate is provided with a right air inlet, and both the left and right air inlets are connected to an external nitrogen-hydrogen mixed gas pipe.

[0008] Preferably, a carbon fiber plate is also fixedly connected to the pressure plate by fasteners.

[0009] Preferably, the pressure plate has evenly distributed pressure plate air passage holes and evenly distributed pressure plate air storage grooves.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, during use, the structure of the heating block and pressure plate with air holes and carbon fiber plate works together to form a protective gas layer on the frame surface. Compared with conventional frames without improvements to the heating block and pressure plate, the technical solution adopted by this utility model allows the frame surface to be covered with a protective gas layer, which can effectively isolate the surrounding oxygen, prevent the frame from undergoing oxidation, extend the service life of the frame, improve the processing quality of the product, enhance the overall structural stability, reduce the likelihood of failure, and make the structure compact and easy to install and maintain. This solves the problem that, with the increasing production requirements, the frames of some materials are prone to reacting with air, and existing gold-copper alloy wire bonding machines do not have an anti-oxidation device, which affects the quality of the formed products.

[0012] 2. In this utility model, during use, the gas is transferred to the surface of the heating block. The surface of the heating block has a bowl-shaped gas storage groove, which allows the gas to be distributed to both sides and stored, acting as a gas storage tank to replenish the lost gas. The structure of the pressure plate gas storage groove is also the same as the bowl-shaped gas storage groove structure on the heating block, which is easy to store gas. Attached Figure Description

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] This utility model provides a sealed track clamp for a gold-copper alloy wire bonding machine, including a heating block 1 and a pressure plate 2. The heating block 1 and the pressure plate 2 cooperate with each other, and are separately installed on corresponding external devices. The pressure plate 2 is provided with an air inlet 3, which is connected to an external nitrogen-hydrogen mixed gas pipe. The heating block 1 has multiple sets of bowl-shaped gas storage grooves 4 and multiple sets of heating block 1 air passage holes. The pressure plate 2 is provided with an air blowing hole 201, which communicates with the multiple sets of heating block 1 air passage holes. A carbon fiber plate 204 is also fixedly connected to the pressure plate 2 by fasteners. The carbon fiber plate 204 has good structural stability.

[0019] In actual use, the sealed track clamp of the gold-copper alloy wire bonding machine has an external nitrogen-hydrogen mixed gas pipe connected to the left side of the heating block 1. Through the connection of the gas passage holes in the heating block 1, the gas passes through the gas passage channel (the interconnected gas passage holes of the heating block 1 form the necessary path for the gas, called the gas passage channel), and is transferred to the surface of the heating block 1. A bowl-shaped gas storage groove 4 is provided on the surface of the heating block 1, allowing the gas to be distributed and stored on both sides, acting as a gas tank to replenish lost gas. The left and right sides of the pressure plate 2 are also connected to external nitrogen-hydrogen mixed gas pipes. Through the connection of the gas passage holes in the pressure plate 2, the gas passes through the gas passage channel and is transferred to the air blowing hole 201 on the bottom surface of the pressure plate 2, causing the frame to... A protective gas layer is applied to the surface, which can effectively isolate the surrounding oxygen and prevent the frame from oxidizing. The carbon fiber plate 204 can block the loss of gas in the window area and also serve as a gas storage function. The protective gas of nitrogen-hydrogen mixture in the surrounding area can effectively delay the oxidation of the frame. Compared with conventional frames without improvements to the heating block 1 and pressure plate 2, the technical solution adopted by this utility model is to apply a protective gas layer to the frame surface, which can effectively isolate the surrounding oxygen, prevent the frame from oxidizing, extend the service life of the frame, improve the processing quality of the product, enhance the overall structural stability, reduce the likelihood of failure, and make the structure compact and easy to install and maintain.

[0020] like Figure 1-2 As shown, a left air inlet 202 is provided on the left side of the pressure plate 2, and a right air inlet 203 is provided on the right side of the pressure plate 2. Both the left air inlet 202 and the right air inlet 203 are connected to an external nitrogen-hydrogen mixed gas pipe. The pressure plate 2 has pressure plate gas passage holes 5 evenly distributed on it, and pressure plate gas storage tanks 501 evenly distributed on it.

[0021] The effect achieved by the entire embodiment 1 is that, during use, the gas is transferred to the surface of the heating block 1, and the surface of the heating block 1 is provided with a bowl-shaped gas storage groove 4, so that the gas can be distributed to both sides and stored, which can act as a gas storage tank to replenish the lost gas. The structure of the pressure plate gas storage groove 501 is also the same as the structure of the bowl-shaped gas storage groove 4 on the heating block 1, which makes it easy to store gas.

[0022] Working principle: The left side of the heating block is connected to an external nitrogen-hydrogen mixed gas pipe. Through the connection of the gas passage holes of the heating block, the gas is transferred to the surface of the heating block through the gas passage channel (the gas passage holes of the heating block are interconnected, forming the necessary path for the gas, called the gas passage channel). The surface of the heating block has a bowl-shaped gas storage groove, which allows the gas to be distributed to both sides and stored, acting as a gas storage tank to replenish the lost gas. The left and right sides of the pressure plate are also connected to external nitrogen-hydrogen mixed gas pipes. Through the connection of the gas passage holes of the pressure plate, the gas is transferred to the air blowing hole on the bottom surface of the pressure plate through the gas passage channel, so that the frame surface is covered with a protective gas layer, which can effectively isolate the surrounding oxygen and prevent the frame from oxidation. The carbon fiber plate can block the gas loss in the window part and also play a role in gas storage. The protective gas of the surrounding nitrogen-hydrogen mixed gas can effectively delay the oxidation of the frame.
