Description

Technical Field

[0001] The utility model relates to the technical field of radio frequency system module packaging, in particular to a gold wire passing device and a gold wire welding machine. Background Art

[0002] Gold wire bonding machine is an automated device that packages radio frequency products through gold wire bonding. Due to the characteristics of gold wire itself, storage time, environment and other factors, gold wire breakage and poor welding are common during the welding process, which not only affects the production efficiency of the equipment, but also has a great impact on the welding yield.

[0003] Gold wire is the main consumable for welding, and its surface cleanliness has a direct impact on the quality of the welding wire. In order to improve the welding yield of gold wire, it is necessary to clean the gold wire before welding to improve the cleanliness of the gold wire surface. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a gold wire passing device and a gold wire welding machine, which are used to improve the surface cleanliness of the gold wire before welding.

[0005] In order to solve the above technical problems, the technical solutions provided by the utility model are as follows:

[0006] A gold wire passing device comprises a frame, on which a spool, a cleaning mechanism, a supporting shaft and a tensioning mechanism are arranged. The cleaning mechanism contains cleaning liquid, and the spool is wound with gold wire. After being cleaned by the cleaning mechanism, the gold wire passes around the supporting shaft and penetrates into the tensioning mechanism.

[0007] In a preferred embodiment, the cleaning mechanism includes a storage tank and a cleaning liquid contained in the storage tank, and the storage tank is provided with a pressing hook for immersing the gold wire into the cleaning liquid.

[0008] In a preferred embodiment, the cleaning liquid is water or an aqueous solution.

[0009] In a preferred embodiment, the storage tank is arranged below the bobbin, and the support shaft is arranged above the storage tank.

[0010] In a preferred embodiment, one end of the pressure hook is provided with a clamping groove adapted to the slot wall of the storage tank, and the other end is provided with a wire passing groove for the gold wire to bypass.

[0011] In a preferred embodiment, one end of the pressing hook having the slot is provided with a bolt, and the bolt extends into the slot and abuts against the slot wall.

[0012] A gold wire welding machine comprises the gold wire passing device. After being cleaned by a cleaning mechanism, the gold wire bypasses a support shaft and penetrates into the tensioning mechanism, and then enters a welding head porcelain nozzle for welding.

[0013] Compared with the prior art, the gold wire passing device and the gold wire bonding machine of this embodiment have the following beneficial effects:

[0014] 1) After the gold wire comes out of the spool, it first passes through the cleaning mechanism, then goes around the support shaft upwards and then passes through the tensioning mechanism for welding. In this way, the gold wire will be cleaned before welding, improving the surface cleanliness of the gold wire before welding;

[0015] 2) The cleaning timeliness is strong, and the cleaning effect can be guaranteed by only regularly replacing the cleaning liquid in the storage tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Explanation of the reference numerals: 1-frame, 2-spool, 3-storage tank, 4-support shaft, 5-tensioning mechanism, 6-gold wire, 7-pressure hook, 31-slot wall, 71-slot, 72-wire slot, 73-bolt. DETAILED DESCRIPTION

[0020] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0021] In the description of the present invention, it is necessary to understand that the terms "up", "down", "left", "right", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the mechanism or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0022] like Figure 1As shown, the gold wire passing device of this embodiment is provided with a frame 1, and the frame 1 is provided with a bobbin 2, a cleaning mechanism, a support shaft 4 and a tensioning mechanism 5. The cleaning mechanism of this embodiment includes a storage tank 3, in which a cleaning liquid is contained, and the storage tank 3 is also provided with a pressing hook 7 for immersing the gold wire 6 in the cleaning liquid. The bobbin 2 is wound with a gold wire 6, and the gold wire 6 bypasses the pressing hook 7 and is cleaned by the cleaning liquid in the storage tank 3, and then bypasses the support shaft 4 and penetrates the tensioning mechanism 5 for welding. When the gold wire 6 passes through the storage tank 3, the pressing hook 7 presses the gold wire 6, which can effectively prevent the gold wire 6 from falling off, and ensure that the gold wire 6 is fully cleaned by the cleaning liquid in the storage tank 3.

[0023] In this embodiment, the cleaning liquid is preferably water or an aqueous solution.

[0024] In this embodiment, the storage tank 3 is preferably disposed below the spool 2 , and the support shaft 4 is preferably disposed above the storage tank 3 , so as to facilitate the cleaning operation of the gold wire 6 .

[0025] like Figure 2 As shown, the left end of the pressing hook 7 is provided with a slot 71 and a bolt 73, and the bolt 73 extends into the slot 71. The right end of the pressing hook 7 is provided with a wire groove 72 for the gold wire 6 to bypass. The wire groove 72 can limit the position of the gold wire 6 when bypassing, ensuring the stability of the gold wire 6 when passing.

[0026] like Figure 3 As shown, the clamping slot 71 is adapted to the slot wall 31 of the storage tank 3. The bolt 73 extends into the clamping slot 71 and abuts against the slot wall 31. The bolt 73 abuts against the slot wall 31 to fix the position of the pressing hook 7 relative to the storage tank 3 in real time, which is more flexible to use.

[0027] After the gold wire welding machine is provided with the gold wire passing device of this embodiment, the gold wire 6 can directly enter the welding head porcelain nozzle on the gold wire welding machine to achieve welding after passing through the tensioning mechanism 5. In this way, the surface of the gold wire is cleaned before welding, thereby improving the welding yield.

[0028] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.
