[0055] An embodiment of the present utility model provides a wire bonding track assembly, referring to Figure 3 、 Figure 4 and Figure 5 , including a support base 3, two track components 4, and a positioning and adjusting mechanism; the two track components 4 are arranged at intervals along the first direction on opposite sides of the support base 3; the first positioning component 1 of the positioning and adjusting mechanism is used to be installed on the support base 3; the two second positioning components 2 of the positioning and adjusting mechanism are respectively used to contact with the two track components 4.

[0056] As an example, the wire bonding track assembly includes a support base 3, two track components 4 and a positioning and adjusting mechanism. The support base 3 is the first workpiece, and the track component 4 is the second workpiece. During installation, the two track components 4 are arranged at intervals on opposite sides of the support base 3 along the first direction. The positioning and adjusting mechanism specifically includes a first positioning component 1 and two second positioning components 2. When in use, the first positioning component 1 is installed on the support base 3 as a reference. Then, the two second positioning components 2 are arranged at intervals on opposite sides of the first positioning component 1 along the first direction and are respectively used to contact the two track components 4. At least one of the two second positioning components 2 is movable along the first direction and is used to position the distance between the two track components 4. In this way, by adjusting the position of one second positioning component 2 on the first positioning component 1, the position of one track component 4 can be adjusted. By adjusting the position of the other second positioning component 2 on the first positioning component 1, the position of the other track component 4 can be adjusted. In this way, the distance between the two track components 4 can be quickly and accurately positioned and adjusted. In this example, by adjusting the positions of the two second positioning components 2 on the first positioning component 1, a positioning reference can be effectively provided for the device to be adjusted, the applicable range of the positioning and adjusting mechanism can be expanded, and the positioning accuracy can be ensured, so as to improve the positioning and adjusting efficiency of the positioning and adjusting mechanism.

[0057] For example, most wire bonding track assemblies (i.e., semiconductor wire bonders) on the market need to run and process materials in specific tracks. Before transporting materials, it is necessary to adjust the track width of the wire bonding track assembly, that is, the distance between the two track components 4, according to the materials to ensure that the track width matches the materials, so as to smoothly transport the materials. Since heat is generated when the materials are transported, the track expands to a certain extent, affecting the originally adjusted track width and thus affecting the processing quality of the material finished products. When adjusting multiple wire bonding track assemblies, the above operations generally need to be repeated, resulting in low adjustment efficiency. Among them, the two track components 4 can be a front track component and a rear track component respectively, or a left track component and a right track component.

[0058] In this example, before adjusting the distance between the two track assemblies 4, the material to be transported is heated. The two track assemblies 4 are adjusted to adapt to the heated finished material, and the two track assemblies 4 are fixed to determine the track width. After the two track assemblies 4 are cooled, the positioning block 13 is placed on the support base 3 and clamped by the clamping block 14. The first positioning plate 11 is placed on the positioning block 13 and positioned by inserting the positioning pin 12. After positioning, move a second positioning plate 21 to be close to one track assembly 4, and move the other second positioning plate 21 to be close to the other track assembly 4. Tighten the two fasteners 22 to determine the track width between the two track assemblies 4. At this time, the width of the entire set of positioning and adjusting mechanisms is the width of the material before heating. When using the entire set of positioning and adjusting mechanisms for the adjustment of the next wire bonding track assembly, rapid adjustment can be achieved and the thermal expansion influence of the material heating on the two track assemblies 4 can be eliminated.

[0059] For most wire bonding track assemblies (i.e., semiconductor wire bonding machines) on the market, the width of the transported material is adjusted according to the width of the material. Since the material expands during heating, the originally adjusted track width does not match the material, and secondary adjustment is required. In this example, by adjusting according to a wire bonding track assembly, the track width that can eliminate heating expansion can be confirmed, and subsequent wire bonding track assembly adjustment can be carried out, thereby improving the adjustment efficiency of the track width of the wire bonding track assembly.

[0060] In one embodiment, referring to Figure 2 , the wire bonding track assembly further includes a working heating area 5. The working heating area 5 is arranged on the support base 3 and is located between the two track assemblies 4; the positioning and adjusting mechanism is installed on the working heating area 5.

[0061] As an example, the wire bonding track assembly further includes a working heating area 5. During installation, the working heating area 5 is arranged on the support base 3 and is located between the two track assemblies 4, and is used for heating and connecting the material and the wire bonding; the positioning and adjusting mechanism is installed on the working heating area 5. In this way, when using the positioning and adjusting mechanism to adjust the track width between the two track assemblies 4, it can be ensured that in the state after adjustment during material transmission, the material corresponds to the working heating area 5 and is located in the center position, improving the heating efficiency of the material and the wire bonding.

[0062] In one embodiment, referring to Figure 3 、 Figure 4 and Figure 5 , the track assembly 4 includes a slide rail 41, a support 42, and a track 43; the slide rail 41 is arranged on the support base 3 along the first direction, the support 42 is movably installed on the slide rail 41 along the first direction, and the track 43 is installed on the support 42.

[0063] As an example, the track assembly 4 includes a slide rail 41, a support 42, and a track 43. During installation, the slide rail 41 is arranged on the support base 3 along the first direction, the support 42 is movably mounted on the slide rail 41 along the first direction, and the track 43 is mounted on the support 42. The first positioning assembly 1 is mounted on the support base 3 of the device to be adjusted as a reference. Then, the second positioning assembly 2 is movably mounted on the first side of the first positioning assembly 1 along the first direction and is used to contact the support 42 of the track assembly 4. By adjusting the position of the second positioning assembly 2, the position of the support 42 on the slide rail 41 can be driven, thereby driving the movement of the support 42 to achieve the positioning adjustment of the track 43. The two second positioning assemblies 2 cooperate to drive the positions of the supports 42 of the two track assemblies 4 on the two slide rails 41 respectively, thereby driving the movement of the two supports 42 to achieve the positioning adjustment of the two tracks 43.

[0064] In one embodiment, referring to Figure 3 、 Figure 4 and Figure 5 , the wire bonding track assembly further includes a locking assembly 6. The locking assembly 6 is mounted on the support base 3 and is used to lock the supports 42 of the two track assemblies 4.

[0065] As an example, the wire bonding track assembly further includes a locking assembly 6. The locking assembly 6 is mounted on the support base 3 and is used to lock the supports 42 of the two track assemblies 4. Specifically, the locking assembly 6 is mounted on the support base 3. At least one strip hole is provided on the locking assembly 6. The strip hole extends along the sliding direction of the two track assemblies 4. A locking member is provided in the strip hole. The locking member is connected to at least one of the two track assemblies 4. By sliding the two track assemblies 4, the locking member can be driven to slide in the first strip hole, and the positions of the two track assemblies 4 on the support base 3 can be adjusted, so that the two track assemblies 4 can be close to or away from each other, thereby adjusting the distance between the two track assemblies 4. Finally, by fixing the locking member, the track assembly 4 can be locked.

[0066] An embodiment of the present invention provides a wire bonder, which includes a wire bonding track assembly.

When in use, the first positioning component 1 is installed on the support base 3 as a reference. Then, the two second positioning components 2 are arranged at intervals along the first direction on opposite sides of the first positioning component 1 and are respectively used to contact the two track assemblies 4. At least one of the two second positioning components 2 is movable along the first direction and is used to position the distance between the two track assemblies 4. In this way, by adjusting the position of one second positioning component 2 on the first positioning component 1, the position of one track assembly 4 can be adjusted. By adjusting the position of the other second positioning component 2 on the first positioning component 1, the position of the other track assembly 4 can be adjusted. In this way, the distance between the two track assemblies 4 can be quickly and accurately positioned and adjusted. In this example, by adjusting the positions of the two second positioning components 2 on the first positioning component 1, a positioning reference can be effectively provided for the device to be adjusted, the applicable range of the positioning and adjusting mechanism can be expanded, and the positioning accuracy can be ensured, so as to improve the positioning and adjusting efficiency of the positioning and adjusting mechanism.

[0068] For example, most wire bonding track assemblies (i.e., semiconductor wire bonding machines) on the market need to run and process materials in specific tracks. Before transporting materials, the track width of the wire bonding track assembly, that is, the distance between the two track assemblies 4, needs to be adjusted according to the materials to ensure that the track width matches the materials, so as to smoothly transport the materials.
