Description

Technical Field

[0001] This utility model relates to the field of annealing technology for bonded copper wire, and in particular to an annealing device for the production of bonded copper wire. Background Technology

[0002] Due to their superior performance and cost, bonding wires have gradually become a new type of wire bonding material, with broad application prospects in LED chip packaging and IC packaging. The continuous annealing heat treatment, intermediate annealing heat treatment and rewinding process of bonding wires are important process links in the production of bonding wires, which determine the final performance of the bonding wires.

[0003] During the feeding process of the bonding wire, oil and dust impurities adhere to the outer wall of the bonding wire. Direct annealing will result in stains on the outer wall of the finished bonding wire, affecting the annealing quality. Therefore, a cleaning structure should be set at the entrance of the annealing equipment. For example, an annealing equipment for processing bonding copper wire provided by patent publication number CN222139179U, through the setting of the material changing mechanism, pushes the fixed frame to move the fixed block and the sponge brush, so that the clean sponge brush replaces the sponge brush that needs to be replaced. Then, the fixed pin is pulled away from the slot, and at the same time, the return spring is stretched and elastically deformed, replacing the used sponge brush with a new one. The sponge brush is fixed by the fixed pin and the return spring, realizing the replacement of sponge brush during the copper wire annealing process, improving the annealing effect of copper wire.

[0004] Based on the above search and combined with existing technology, it was found that although the cleaning structure of existing annealing equipment for bonding copper wire processing, similar to the disclosed above, is easy to replace, it does not clean the copper wire thoroughly enough, leaving cleaning dead zones in the upper and lower gaps of the sponge brush. Furthermore, during the cleaning process before annealing, it is difficult for personnel to see the contamination status of the sponge brush, making it difficult to replace it in a timely manner. Long-term neglect of sponge brush replacement leads to a decrease in the cleaning effect on the copper wire, thereby reducing the annealing quality of the copper wire. Therefore, an annealing device for the production of bonding copper wire is proposed to improve the above problems. Utility Model Content

[0005] The purpose of this application is to provide an annealing apparatus for the production of bonding copper wires, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: an annealing device for producing bonding copper wire, comprising an annealing box for the copper wire to pass through, an mounting base installed on the outer wall of the annealing box on the side for the copper wire to enter, a wire guide wheel installed on the side of the mounting base near the annealing box, and a cleaning mechanism installed at the upper end of the mounting base.

[0007] The cleaning mechanism includes a first cleaning component and a second cleaning component, which are arranged sequentially along the conveying direction of the annealing box;

[0008] Both the first and second cleaning components include a support frame, a rotating roller, and an annular sponge brush.

[0009] The support frame is fixed to the upper end of the mounting base. The middle of the support frame is provided with a through hole for copper wire to pass through. Multiple rotating rollers are provided, and the length direction of the multiple rotating rollers is all along the conveying direction of the copper wire. The multiple rotating rollers are rotatably mounted on one side of the support frame.

[0010] An annular sponge brush is sequentially wound between a copper wire and multiple rotating rollers. The annular sponge brush on the first cleaning assembly forms a U-shape, and the annular sponge brush on the second cleaning assembly forms an inverted U-shape. The cross-sectional length of the annular sponge brush covering the copper wire is greater than half the circumference of the copper wire cross-section.

[0011] As a further supplement to this scheme, the rotating roller is rotatably mounted on the end face of the support frame away from the annealing box.

[0012] As a further supplement to this solution, a drive motor is installed on the side of the support frame near the annealing box, and the output end of the drive motor is coaxially fixed with one of the rotating rollers.

[0013] As a further supplement to this solution, a limit ring is coaxially integrated at the end of the rotating roller near the support frame.

[0014] As a further supplement to this solution, the end of the rotating roller away from the support frame is threaded with an anti-detachment ring.

[0015] As a further supplement to this solution, both the first cleaning component and the second cleaning component are provided in two sets.

[0016] In summary, the technical effects and advantages of this utility model are as follows:

[0017] 1. In this utility model, by forming a concave shape on the annular sponge brush on the first cleaning component and an inverted concave shape on the annular sponge brush on the second cleaning component, and by ensuring that the cross-sectional length of the copper wire covered by the annular sponge brush is greater than half of the circumference of the copper wire cross-section, it is guaranteed that the copper wire can be thoroughly cleaned. Furthermore, the winding and matching of the annular sponge brush with the rotating roller facilitates quick disassembly and replacement of the annular sponge brush.

[0018] 2. In this utility model, a drive motor is installed on the side of the support frame near the annealing box. The output end of the drive motor is coaxially fixed with one of the rotating rollers. The drive motor drives the rotating roller to rotate slowly, which can cause the annular sponge brush to move, thereby automatically changing the part in contact with the copper wire. The end face of the annular sponge brush in contact with the copper wire is located outside the rotating roller, which makes it convenient for personnel to check the degree of contamination of the annular sponge brush, thus facilitating timely replacement.

[0019] 3. In this utility model, by setting two sets of the first cleaning component and the second cleaning component, only one set of the first cleaning component and the second cleaning component is equipped with an annular sponge brush to thoroughly clean the copper wire within the same time period. When replacement is needed, the new annular sponge brush is first installed between the rotating roller and the copper wire on the other set of the first cleaning component and the second cleaning component, and then the old annular sponge brush on the original first cleaning component and the second cleaning component is removed. This can well meet the needs of continuous annealing operations. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Reference Figure 1-4 An annealing apparatus for producing bonding copper wires is shown, including an annealing box 1 through which the copper wire 2 passes. Of course, the annealing box 1 has a conventional annealing structure (not shown in the figure), such as a conventional heating module, heat preservation module and cooling module. A mounting base 3 is installed on the outer wall of the annealing box 1 on the side through which the copper wire 2 enters. A wire guide wheel 4 is installed on the side of the mounting base 3 near the annealing box 1. A cleaning mechanism is installed on the upper end of the mounting base 3.

[0028] The cleaning mechanism includes a first cleaning component 5 and a second cleaning component 6, which are arranged sequentially along the conveying direction of the annealing box 1. Specifically, both the first cleaning component 5 and the second cleaning component 6 include a support frame 561, a rotating roller 562, and an annular sponge brush 563. More specifically, the support frame 561 is fixed to the upper end of the mounting base 3, and a through hole 5601 for the copper wire 2 to pass through is provided in the middle of the support frame 561. Multiple rotating rollers 562 are provided, and the length direction of the multiple rotating rollers 562 is arranged along the conveying direction of the copper wire 2. The multiple rotating rollers 562 are rotatably installed on one side of the support frame 561, and the annular sponge brush 563 is sequentially wound between the copper wire 2 and the multiple rotating rollers 562.

[0029] The annular sponge brush 563 on the first cleaning component 5 forms a concave shape, and the annular sponge brush 563 on the second cleaning component 6 forms an inverted concave shape. The cross-sectional length of the annular sponge brush 563 covering the copper wire 2 is greater than half of the cross-sectional perimeter of the copper wire 2, ensuring that the copper wire 2 can be thoroughly cleaned. The winding and matching of the annular sponge brush 563 and the rotating roller 562 facilitates quick disassembly and replacement of the annular sponge brush 563.

[0030] To prevent the annular sponge brush 563 from detaching from the rotating roller 562 due to friction from the copper wire 2, the rotating roller 562 is rotatably mounted on the side end face of the support frame 561 away from the annealing box 1.

[0031] Among them, a drive motor 564 is installed on the side end of the support frame 561 near the annealing box 1. The output end of the drive motor 564 is coaxially fixed with one of the rotating rollers 562. The drive motor 564 drives the rotating roller 562 to rotate slowly, which can cause the annular sponge brush 563 to move, thereby automatically changing the part in contact with the copper wire 2. The end face of the annular sponge brush 563 in contact with the copper wire 2 is located outside the rotating roller 562, which makes it convenient for personnel to check the degree of contamination of the annular sponge brush 563 and thus facilitate timely replacement.

[0032] Among them, a limit ring 566 is coaxially integrated at one end of the rotating roller 562 near the support frame 561 to prevent the moving annular sponge brush 563 from rubbing against the support frame 561.

[0033] In order to better limit the annular sponge brush 563 on the rotating roller 562, an anti-detachment ring 565 is threaded onto the end of the rotating roller 562 away from the support frame 561.

[0034] To meet the requirements of continuous annealing operations, two sets of the first cleaning component 5 and the second cleaning component 6 are provided. At any given time, only one set of the first cleaning component 5 and the second cleaning component 6 is equipped with an annular sponge brush 563 to thoroughly clean the copper wire 2. When replacement is required, the new annular sponge brush 563 is first installed between the rotating roller 562 and the copper wire 2 on the other set of the first cleaning component 5 and the second cleaning component 6, and then the old annular sponge brush 563 on the original first cleaning component 5 and the second cleaning component 6 is removed.

[0035] The working principle of this utility model is as follows: During use, only one set of first cleaning components 5 and second cleaning components 6, equipped with annular sponge brushes 563, can thoroughly clean the copper wire 2 within a single time period. Specifically, the drive motor 564 drives the rotating roller 562 to rotate slowly, causing the annular sponge brush 563 to move and automatically change the part in contact with the copper wire 2. The end face of the annular sponge brush 563 in contact with the copper wire 2 is located outside the rotating roller 562, making it convenient for personnel to check the degree of contamination of the annular sponge brush 563 and thus facilitate timely replacement. When replacement is needed, a new annular sponge brush 563 is first installed between the rotating roller 562 and the copper wire 2 on another set of first cleaning components 5 and second cleaning components 6, and then the old annular sponge brush 563 on the original first cleaning components 5 and second cleaning components 6 is removed.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
