Description

Technical Field

[0001] This application relates to the field of welding technology, and in particular to a solder wire feeding structure and a die bonder. Background Technology

[0002] The solder wire feed structure is an essential part of the solder die bonder. Existing solder wire structures have two fixing methods for the shaft. One method is to fix the shaft, where the inner hole of the solder wire reel and the shaft have dry friction, resulting in high frictional resistance and causing the solder wire to be fed unevenly. The other method is to install a bearing on the shaft, with the solder wire reel fixed on the shaft and rotating with the shaft. This fixing method is very prone to overshoot, causing the solder wire to swing from side to side. Both of these methods can lead to unstable solder wire feeding. Utility Model Content

[0011] In one embodiment, multiple rotating components and multiple solder wire reels are provided, and the multiple rotating components and multiple solder wire reels are connected in a one-to-one correspondence.

[0012] In one embodiment, an insulating element is also included, through which the protective cover is connected to the mounting platform.

[0039] This application provides a solder wire feeding structure, such as Figures 1 to 7 As shown, the solder wire feeding structure includes: a protective cover 100, a rotating assembly 200, and a solder wire reel 300. The protective cover 100 has a receiving cavity 110. The rotating assembly 200 is disposed in the receiving cavity 110 and includes a rotating shaft 210 and a damper 220 connected to each other. The rotating shaft 210 is rotatably connected to the cavity wall of the receiving cavity 110. The solder wire reel 300 is sleeved on the rotating shaft 210 and fixed to the rotating shaft 210. The solder wire reel 300 is used to wind the solder wire 310, and the solder wire 310 can extend out of the protective cover 100.

[0040] The aforementioned solder wire feeding structure protects the rotating assembly 200 and the solder wire reel 300 by providing a rotating assembly 200 and a solder wire reel 300 within the receiving cavity 110 of the protective cover 100, preventing external dust or water droplets from falling onto them. Furthermore, the rotating shaft 210 is rotatably connected to the cavity wall of the receiving cavity 110, thus fixing the rotating assembly 200. The solder wire reel 300 is sleeved on and fixed to the rotating shaft 210. The solder wire 310 wound on the solder wire reel 300 can pass through the receiving cavity 110 and be positioned outside the protective cover 100. By pulling the solder wire 310, the solder wire reel 300 can drive the rotating shaft 210 to rotate synchronously. A damper 220 is installed on the rotating shaft 210 to absorb and disperse the vibrations and shocks generated by the rotating shaft 210, thereby improving the stability and reliability of the rotating shaft 210, reducing the frequency of the oscillation of the solder wire 310, and the damper 220 helps the rotating shaft 210 to quickly return to a stable state after being subjected to instantaneous impact, further improving the rotational stability of the rotating shaft 210, reducing the oscillation of the solder wire 310, and improving the stability of the feeding of the solder wire 310.

[0041] See also Figures 3 to 5 The rotating assembly 200 includes a plunger 230, which includes a first mounting portion and a second mounting portion connected to each other. The first mounting portion is connected to the rotating shaft 210, and the second mounting portion can engage with the solder wire reel 300. The first mounting portion of the plunger 230 is connected to the rotating shaft 210, thus providing the plunger 230 on the rotating shaft 210. When the solder wire reel 300 is fitted onto the rotating shaft 210, the second mounting portion of the plunger 230 can engage with the solder wire reel 300, thereby defining the relative position of the solder wire reel 300 and the rotating shaft 210.

[0042] Specifically, the first mounting part is threadedly connected to the rotating shaft 210, and the second mounting part is elastic. Specifically, as... Figure 3 As shown, the plunger 230 has a rod-shaped structure and is perpendicular to the axial direction of the rotating shaft 210.

[0043] Specifically, such as Figure 3 As shown, multiple plungers 230 are provided. In this embodiment, two plungers 230 are provided; in other embodiments, three, four, or even more plungers 230 may be provided.

[0044] More specifically, if Figure 3 As shown, multiple plungers 230 are arranged circumferentially or axially along the rotating shaft 210. In this embodiment, two plungers 230 are arranged axially along the rotating shaft 210. In other embodiments, the plungers 230 may also be arranged at intervals circumferentially around the rotating shaft 210.

[0045] Specifically, Figures 3 to 5As shown, the rotating assembly 200 includes a fixed base 240 and a bearing 250. The fixed base 240 is connected to the cavity wall of the receiving cavity 110. The bearing 250 is sleeved on the rotating shaft 210, with the rotating part of the bearing 250 connected to the rotating shaft 210 and the fixed part of the bearing 250 connected to the fixed base 240. By sleeved the bearing 250 on the rotating shaft 210, with the fixed part of the bearing 250 connected to the fixed base 240, and the fixed base 240 connected to the cavity wall of the receiving cavity 110, the rotating shaft 210 is rotatably connected to the cavity wall of the receiving cavity 110. Because the rotating part of the bearing 250 is connected to the rotating shaft 210, the rotating shaft 210 can rotate relative to the fixed base 210.

[0046] More specifically, Figures 3 to 5 As shown, the fixed seat 240 is sleeved on the rotating shaft 210, and the tin wire reel 300 and the damper 220 are disposed on both sides of the fixed seat 240 along the axial direction of the rotating shaft 210.

[0047] Specifically, Figures 3 to 5 As shown, the rotating assembly 200 also includes a mounting base 260 connected to the fixed base 240. The damper 220 includes a rotating part and a connecting part that are rotatably engaged. The rotating part is connected to the rotating shaft 210, and the connecting part is connected to the mounting base 260. By setting the mounting base 260, the rotating part of the damper 220 is connected to the rotating shaft 210. The rotation of the rotating shaft 210 drives the rotating part of the damper 220 to rotate synchronously. The connecting part of the damper 220 is connected to the mounting base 260, and the mounting base 260 is connected to the fixed base 240. The connecting part of the damper 220 is connected to the fixed base 240 through the mounting base 260, thereby fixing the damper 220.

[0048] More specifically, Figures 3 to 5 As shown, the mounting base 260 is located on the side of the fixed base 240 near the damper 220.

[0049] More specifically, Figures 3 to 5 As shown, the mounting part of the damper 220 includes a mounting plate 221, and a locking member passes through the mounting plate 221 and is connected to the mounting base 260, thereby realizing the connection between the mounting part and the mounting base 260.

[0050] Specifically, such as Figure 1 and Figure 2 ,as well as Figure 6 and Figure 7As shown, the solder wire feeding structure also includes a mounting shell 120 disposed within the receiving cavity 110 and connected to the cavity wall of the receiving cavity 110. The mounting shell 120 has a third cavity communicating with the receiving cavity 110. The damper 220 is disposed within the third cavity, the rotating shaft 210 extends out of the third cavity, and the fixing seat 240 is disposed outside the third cavity and connected to the mounting shell 120. By providing the mounting shell 120, the damper 220 of the rotating assembly 200 is disposed inside the third cavity of the mounting shell 120, the fixing seat 240 of the rotating assembly 200 is disposed outside the third cavity, and the rotating shaft 210 is partially disposed outside the third cavity and partially passes through the mounting shell 120 and extends into the third cavity to connect with the damper 220. By connecting the fixing seat 240 of the rotating assembly 200 to the mounting shell 120, and the mounting shell 120 being connected to the cavity wall of the receiving cavity 110, the connection between the rotating assembly 200 and the cavity wall of the receiving cavity 110 is realized.

[0051] More specifically, if Figures 1 to 3 ,as well as Figure 6 and Figure 7 As shown, a screw hole is provided on the fixing base 240, and the locking member passes through the screw hole of the fixing base 240 and is threaded to the mounting shell 120, thereby realizing the connection between the fixing base 240 and the mounting shell 120.

[0052] Specifically, multiple rotating components 200 and multiple solder wire reels 300 are provided, and the multiple rotating components 200 and the multiple solder wire reels 300 are connected in a one-to-one correspondence. By providing multiple solder wire reels 300, and each solder wire reel 300 is provided with a corresponding rotating component 200, the feed rate of solder wire 310 per unit time is increased.

[0053] More specifically, in this embodiment, there are two solder wire 310 turntables and two sets of rotating components 200. The two solder wire 310 turntables are arranged along the second direction, and the rotating shafts 210 of the two sets of rotating components 200 are arranged at intervals along the second direction, wherein the second direction is perpendicular to the feeding direction of the solder wire 310.

[0054] It should be noted that the feeding direction of the solder wire 310 of the solder wire reel 300 is the direction in which the solder wire 310 passes through the receiving cavity 110 and extends outward. Figure 1 , Figure 2 as well as Figure 6 From the perspective of [the source], the feed direction of the tin wire 310 is vertically downward.

[0055] Specifically, such as Figure 1 and Figure 2 ,as well as Figure 6 and Figure 7As shown, the receiving cavity 110 includes a first cavity 111 and a second cavity 112. The rotating assembly 200 and the solder wire reel 300 are both disposed in the first cavity 111, and the second cavity 112 is used to store new reels. The rotating assembly 200 and the solder wire reel 300 are disposed in the first cavity 111, and the second cavity 112 can be used to store unused solder wire reels 300, thereby facilitating the replacement of the used solder wire reels 300 in the first cavity 111.

[0056] More specifically, if Figure 1 and Figure 2 ,as well as Figure 6 and Figure 7 As shown, a storage box 160 is provided in the second cavity 112, and the solder wire reel 300 to be used is placed in the storage box 160.

[0057] More specifically, if Figure 1 and Figure 2 ,as well as Figure 6 and Figure 7 As shown, the protective cover 100 includes a first plate 130, a second plate 140, and a third plate 150 connecting the first plate 130 and the second plate 140. The first plate 130 and the second plate 140 are arranged along a first direction, and the first plate 130, the second plate 140, and the third plate 150 surround to form a receiving cavity 110. The receiving cavity 110 is divided into a first cavity 111 and a second cavity 112 along a second direction. The second plate 140 is provided with an opening 141 for solder wire 310 to pass through in the area corresponding to the first cavity 111. The first direction is the feeding direction of the solder wire 310, and the second direction is perpendicular to the first direction. By setting the first plate 130, the second plate 140, and the third plate 150, the receiving cavity 110 is formed, and the receiving cavity 110 is divided into a first cavity 111 and a second cavity 112 along the second direction. A rotating assembly 200 and a solder wire reel 300 are provided in the first cavity 111, and a storage box 160 is provided in the second cavity 112. Furthermore, an opening 141 is made in the area of ​​the second plate 140 corresponding to the first cavity 111, and the solder wire 310 of the solder wire reel 300 in the first cavity 111 extends out of the protective cover 100 through the opening 141.

[0058] More specifically, the size of the opening 141 is set according to the actual operation requirements. In some embodiments, each solder wire 310 of each solder wire reel 300 is provided with a corresponding opening 141. In this embodiment, the size of the opening 141 along the second direction is greater than the distance between the two solder wire reels 300 along the second direction, so that the solder wires 310 of the two solder wire reels 300 extend through the same opening 141.

[0059] Specifically, such as Figure 1 and Figure 2 ,as well as Figure 6 and Figure 7As shown, the solder wire feeding structure also includes a door panel 500 and a handle 600 disposed on the door panel 500. The door panel 500 is rotatably connected to the third plate 150 to block the first cavity 111. By setting the door panel 500 and rotatably connecting it to the third plate 150, the space of the first cavity 111 is blocked by the door panel 500. The handle 600 is provided on the door panel 500 to facilitate the rotation of the door panel 500 relative to the third plate 150.

[0060] More specifically, if Figure 1 and Figure 2 ,as well as Figure 6 and Figure 7 As shown, the door panel 500 is L-shaped and is rotatably connected to the third plate 150 via a hinge 510.

[0061] Specifically, such as Figure 1 and Figure 2 ,as well as Figure 6 and Figure 7 As shown, the solder wire feeding structure also includes an insulating component 400, and the protective cover 100 is connected to the mounting platform via the insulating component 400. By providing the insulating component 400, the solder wire feeding structure is insulated relative to the mounting platform, thereby improving the insulation performance of the solder wire feeding structure.

[0062] More specifically, in this embodiment, the insulating member 400 includes two insulating plates, which are sandwiched between the protective cover 100. The locking member passes through one insulating plate, the protective cover 100, and another insulating plate in sequence and is threaded to the mounting platform, thereby fixing the solder wire feeding structure on the mounting platform.

[0063] This application also provides a die bonding machine, including the aforementioned solder wire feeding structure. The die bonding machine of this application, by installing a damper on the rotating shaft of the solder wire feeding structure, absorbs and disperses the vibrations and shocks generated by the rotating shaft, thereby improving the stability and reliability of the rotating shaft, reducing the frequency of solder wire oscillation, improving the stability of solder wire feeding, and thus improving the processing efficiency of the die bonding machine.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application.
