Description

Technical Field

[0001] The utility model relates to the technical field of wire bonding machines, in particular to a transducer cooling device. Background Art

[0002] The wire bonder is one of the core equipment in the back-end of semiconductor packaging. The bonding head is the most important component of the wire bonder, and the transducer is an important component of the bonding head. The quality of wire bonding is directly related to the stability of the transducer.

[0003] Existing wire bonding machines typically have a transducer fixed to a mounting base, which in turn connects to a bonding head via the mounting base. When the transducer is operating, it sits directly below a heating table, which typically operates at temperatures between 120°C and 250°C. Because the transducer and the heating table are very close, typically within 2mm, and the operating temperature of the heating table is typically around 120°C, prolonged close contact between the transducer and the heating table inevitably causes the transducer to heat up, resulting in thermal expansion and contraction, affecting the transducer's impedance. This impedance change can lead to unstable power output, thus affecting wire bonding performance. Utility Model Content

[0019] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0020] like Figures 1 to 3As shown, the transducer cooling device of the present invention includes a thermally insulating upper shell 1, a thermally insulating bottom shell 2, and a thermally insulating baffle 3. The thermally insulating bottom shell 2 extends to form a first extension portion 201 and a second extension portion 202 disposed opposite each other, with a recessed portion 203 formed between the first extension portion 201 and the second extension portion 202. The thermally insulating baffle 3 covers the recessed portion 203, and the recessed portion 203 and the thermally insulating baffle 3 together form a ventilation cavity. The thermally insulating upper shell 1 is mounted on the first extension portion 201, and an air duct is formed between the thermally insulating upper shell 1 and the first extension portion 201, which connects to the ventilation cavity.

[0021] Furthermore, at least one air guide strip 4 is provided within the recessed portion 203 to guide the compressed air within the vent cavity, ensuring that the incoming compressed air flows along designated areas and routes, thereby achieving uniform and effective cooling. The first extension 201 is provided with an air inlet 205, which communicates with the air duct. An air outlet 204 is provided on a side of the insulated bottom shell 2, away from the air inlet 205, and communicates with the vent cavity.

[0022] In this embodiment, three air outlets 204 are provided on the side of the insulating bottom shell 2 away from the air inlet 205, which effectively ensures the timeliness of heat dissipation and makes the performance of the transducer 6 more stable; it can be understood that in other embodiments, only one air outlet 204 or more than four air outlets 204 can be provided, and this is not limited to this.

[0023] In another preferred embodiment, the heat-insulating upper shell 1 , the heat-insulating baffle 3 and the heat-insulating bottom shell 2 may also be integrally formed, but the present invention is not limited thereto.

[0024] In addition, the heat insulation plate 3 , the first extension portion 201 and the second extension portion 202 together form a mounting groove 5 for mounting the transducer 6 .

[0025] like Figure 1 and Figure 4 As shown, a transducer 6 is installed in the installation groove 5, and a fixing seat 7 is installed at the rear end of the transducer 6; a heating workbench 8 is provided below the transducer 6, and the heat-insulating bottom shell 2 is located between the heating workbench 8 and the transducer 6.

[0026] The working principle of the transducer cooling device of the present invention is as follows:

[0027] During operation, since the transducer 6 is close to the heating workbench, in order to prevent the transducer 6 from being affected by the high temperature of the heating workbench, the transducer 6 needs to be cooled. At this time, compressed air is introduced through the air inlet 205, and the compressed air enters the ventilation cavity through the air duct, is guided by the air guide strip 4, and is finally discharged from the air outlet 204. While flowing, the compressed air absorbs the heat transmitted from the insulation base plate, thereby taking away part of the heat of the transducer 6 located in the installation groove 5, thereby achieving the purpose of cooling the transducer 6, making the performance of the transducer 6 more stable, ensuring the stability of the welding line effect, and improving the welding line quality.

[0028] In summary, the transducer cooling device of the present invention has the following advantages:

[0029] 1. Compressed air is introduced through the air inlet 205, enters the ventilation cavity through the air duct, is guided by the air guide strip 4, and is finally discharged from the air outlet 204. While flowing, the compressed air absorbs the heat transmitted from the heat-insulating bottom plate, thereby taking away part of the heat of the transducer 6 located in the mounting groove 5, thereby achieving the purpose of cooling the transducer 6, making the performance of the transducer 6 more stable, ensuring the stability of the welding effect, and improving the welding quality.

[0030] 2. An air guide strip 4 is provided in the recessed portion 203 to guide the compressed air to circulate in the ventilation cavity, so that the incoming compressed air can flow in designated areas and lines, thereby achieving the purpose of uniform and effective cooling.
