Description

Technical Field

[0001] This utility model relates to the field of bonding wire production and processing technology, and in particular to a cleaning device for bonding wires. Background Technology

[0002] Bonding wires are widely used products, such as integrated circuits, large-scale integrated wafers, and transistors. Their advantage is that they can meet different types of packaging requirements. After the bonding wires are manufactured, their surfaces need to be cleaned.

[0003] A search of Chinese Patent CN210632507U reveals a cleaning device for bonding wires, comprising a frame and a cleaning mechanism. The cleaning mechanism is housed within the frame. The frame includes a housing with a water inlet on the top left side and a water outlet on the bottom right side. A first mounting plate is located on the left side of the housing, with a feed roller on its top. A second mounting plate is located on the right side of the housing, with a take-up roller on its top. Two guide rollers are located on the bottom of the inner wall of the housing. This patent, through the cooperation between the frame and the cleaning mechanism, provides a cleaning device for bonding wires. It allows for adjustment of the pressure exerted on the bonding wires by the first and second cleaning brushes, making it suitable for cleaning bonding wires of different specifications. Furthermore, it enables the cleaning of the bonding wires by absorbing and drying water, thus ensuring the quality of the cleaning process.

[0004] Based on the above search results and existing technologies, the following findings were made: While the above technology can absorb water from the bonded fibers after cleaning, a large amount of water will accumulate inside the absorbent sponge over a long period of time. If it is used directly without cleaning, the water absorption effect on the bonded fibers will decrease, resulting in a decline in the cleanliness of the bonded fibers. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model proposes a cleaning device for bonding wires, which can automatically clean the absorbent sponge after the bonding wires are cleaned, thus avoiding the situation where the absorbent sponge contains cleaning liquid or water, which would lead to poor cleaning effect of the bonding wires.

[0006] The technical solution to achieve the purpose of this utility model is as follows: a cleaning device for bonding wires, including a cleaning outer box, with inlet and outlet ports on both sides of the cleaning outer box, and mounting plates fixedly installed on the cleaning outer box at positions corresponding to the inlet and outlet ports. A feeding roller is installed on the left mounting plate, which is used to feed the bonding wires into the interior of the cleaning outer box. A circular rod is installed on the right mounting plate, and a receiving roller is sleeved on the circular rod. Two mounting plates are installed inside the cleaning outer box, and multiple feeding rollers are movably installed on the mounting plates. An inner cleaning box is installed inside the cleaning outer box, and two cleaning brushes are movably installed inside the inner cleaning box. A water suction mechanism is provided on the cleaning outer box. The water absorption mechanism includes a collection box, a filter screen, a water-absorbing sponge, and a pressure plate. The collection box is fixedly installed inside the upper part of the outer cleaning box, the filter screen is fixedly installed inside the upper part of the inlet and outlet, and the pressure plate is movably installed above the collection box. There are two water-absorbing sponges, which are respectively installed at the bottom of the filter screen and the pressure plate. A transmission mechanism is provided on the outer cleaning box.

[0007] In some embodiments, the transmission mechanism includes a transmission groove, a first transmission gear plate, a rotating shaft, a transmission gear, a second transmission gear plate, and a second pressure plate. The transmission groove is a rectangular groove that is located on the right side wall of the outer cleaning chamber. The first transmission gear plate is movably installed inside the transmission groove. The rotating shaft is movably installed inside the outer cleaning chamber. The transmission gear is movably sleeved on the rotating shaft. The second transmission gear plate is movably installed inside the outer cleaning chamber. The second pressure plate is fixedly installed at the bottom of the second transmission gear plate, and the second pressure plate is fixedly connected to the first pressure plate.

[0008] In some embodiments, the bottom of the first transmission toothed plate is located at the top of the receiving roller, and the transmission gear meshes with the second transmission toothed plate and the first transmission toothed plate respectively.

[0009] In some embodiments, a drive motor is installed at the bottom of the right mounting plate, and the output end of the drive motor passes through the mounting plate and is fixedly connected to a circular rod on the mounting plate.

[0010] In some embodiments, a support rod is fixedly installed between the transmission gear plate 2 and the pressure plate 2.

[0011] In some embodiments, mounting blocks are fixedly installed at corresponding positions on the side walls of the collection box and the pressure plate. A reset rod is fixedly installed at the bottom of the upper mounting block, and the reset rod penetrates downward through the upper and lower walls of the lower mounting block. A reset spring is sleeved on the reset rod.

[0012] Compared with existing technologies, the significant advantages of this invention are: This invention, through the setting of a transmission mechanism, allows a roll of bonding wire to be collected onto a drive motor after cleaning. At this point, the drive motor can be removed from the circular rod on mounting plate one, and the drive motor moves upward away from the circular rod. The drive motor then drives transmission gear one to move upward, which in turn drives transmission gear one to rotate. The rotation of the transmission gear drives transmission gear two to move downward inside the cleaning chamber. Transmission gear two, in turn, drives pressure plate two to move downward, squeezing pressure plate one downward. Pressure plate one then squeezes two absorbent sponges between itself and the filter screen. This squeezing forces out the cleaning liquid or water absorbed by the two absorbent sponges, which is then collected in the collection box. This achieves the effect of automatically cleaning the absorbent sponges after the bonding wire cleaning is completed, avoiding the situation where the absorbent sponges contain cleaning liquid or water, leading to poor subsequent bonding wire cleaning.

Detailed Implementation

[0015] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0016] This invention provides an improved cleaning device for bonding wires. The technical solution of this invention is as follows: like Figures 1 to 4 As shown, a cleaning device for bonding wires includes a cleaning outer casing 1, which is a hollow rectangular structure. Both sides of the outer casing 1 have inlet and outlet ports 10. Mounting plates 2 are fixedly installed on the outer casing 1 at positions corresponding to the inlet and outlet ports 10. Mounting plates 2 are rectangular structures. A feed roller 3 is installed on the left mounting plate 2, used to feed the bonding wires into the interior of the cleaning outer casing 1. A circular rod is installed on the right mounting plate 2, with a receiving roller 4 sleeved on the rod, used to collect the cleaned bonding wires. Two... Mounting plate 2 6 is a rectangular plate with multiple feeding rollers 7 movably mounted on it. The feeding rollers 7 are cylindrical and the bonding wire moves between them. The feeding rollers 7 tighten the bonding wire. Cleaning inner box 8 is installed inside the cleaning outer box 1. Two cleaning brushes 9 are movably mounted inside the cleaning inner box 8. The bonding wire passes between the two cleaning brushes 9, which can be driven to rotate by external power. The cleaning inner box 8 is filled with cleaning fluid or water to clean the bonding wire. The cleaning outer box 1 is equipped with a water suction mechanism. The water absorption mechanism includes a collection box 11, a filter screen 12, a water-absorbing sponge 13, and a pressure plate 14. The collection box 11 is a hollow rectangular structure and is fixedly installed inside the upper part of the cleaning outer box 1. The filter screen 12 is fixedly installed inside the upper part of the inlet / outlet 10. The pressure plate 14 is a rectangular plate and is movably installed above the collection box 11. There are two water-absorbing sponges 13, which are respectively installed at the bottom of the filter screen 12 and the pressure plate 14. The bonding wire can pass between the two water-absorbing sponges 13, thereby cleaning away the residual cleaning liquid or water on the bonding wire. A transmission mechanism is provided on the cleaning outer box 1. The transmission mechanism includes a transmission groove 15, a first transmission gear plate 16, a rotating shaft 17, a transmission gear 18, a second transmission gear plate 19, and a second pressure plate 20. The transmission groove 15 is a rectangular groove located on the right side wall of the outer cleaning chamber 1. The first transmission gear plate 16 is an "L"-shaped plate, movably installed inside the transmission groove 15, with its bottom located at the top of the receiving roller 4. The rotating shaft 17 is cylindrical and movably installed inside the outer cleaning chamber 1. The transmission gear 18 is movably sleeved on the rotating shaft 17. The second transmission gear plate 19 is a rectangular plate, movably installed inside the outer cleaning chamber 1. The transmission gear 18 meshes with both the second transmission gear plate 19 and the first transmission gear plate 16. The second pressure plate 20 is a rectangular plate, fixedly installed at the bottom of the second transmission gear plate 19, and fixedly connected to the first pressure plate 14. Through the arrangement of the transmission mechanism, when... After cleaning, a roll of bonding wire is collected onto the take-up roller 4. At this point, the take-up roller 4 can be removed from the circular rod on the mounting plate 2. The take-up roller 4 moves upward away from the circular rod, and the transmission gear plate 16 is driven upward by the take-up roller 4. The transmission gear plate 16 drives the transmission gear 18 to rotate. The rotation of the transmission gear 18 drives the transmission gear plate 19 to move downward inside the cleaning outer box 1. The transmission gear plate 19 then drives the pressure plate 20 to move downward. The pressure plate 20 squeezes the pressure plate 14 downward. The pressure plate 14 then squeezes the two absorbent sponges 13 downward between the pressure plate and the filter screen 12. The squeezing causes the cleaning liquid or water absorbed by the two absorbent sponges 13 to be squeezed out and then collected by the collection box 11. This achieves the effect of automatically cleaning the absorbent sponges 13 after the bonding wire is cleaned, avoiding the situation where the absorbent sponges 13 contain cleaning liquid or water, which would lead to poor cleaning effect of the subsequent bonding wire.

[0017] A drive motor 5 is installed at the bottom of the right mounting plate 12. The output end of the drive motor 5 passes through the mounting plate 12 and is fixedly connected to the circular rod on the mounting plate 12. The receiving roller 4 can be driven to rotate through the mounting plate 26, thereby achieving the effect of automatically collecting bonding wires.

[0018] A support rod 21 is fixedly installed between the transmission gear plate 29 and the pressure plate 20. The support rod 21 can improve the stability of force transmission between the transmission gear plate 29 and the pressure plate 20.

[0019] Mounting blocks 22 are fixedly installed at corresponding positions on the side walls of the collection box 11 and the pressure plate 14. The mounting blocks 22 are rectangular blocks. A reset rod 23 is fixedly installed at the bottom of the upper mounting block 22. The reset rod 23 is cylindrical and extends downward through the upper and lower walls of the lower mounting block 22. A reset spring 24 is sleeved on the reset rod 23. When the pressure plate 14 moves downward, it will cause the upper mounting block 22 to press down on the reset spring 24. After the water is squeezed out, the pressure plate 14 can be reset by the elastic force of the reset spring 24.

[0020] The specific working method is as follows: Through the transmission mechanism, after a roll of bonding wire is cleaned, it is collected on the drive motor 5. At this time, the drive motor 5 can be removed from the circular rod on the mounting plate 1 2. The drive motor 5 moves upward away from the circular rod, and the transmission gear plate 1 16 is driven upward by the drive motor 5. The transmission gear plate 1 16 can drive the transmission gear 18 to rotate. The rotation of the transmission gear 18 can drive the transmission gear plate 2 19 to move downward inside the cleaning outer box 1. The transmission gear plate 2 19 then drives the pressure plate 2 20 to move downward. The pressure plate 2 20 squeezes the pressure plate 1 14 downward. The pressure plate 1 14 then squeezes the two absorbent sponges 13 downward between the pressure plate 14 and the filter screen 12. The squeezing can squeeze out the cleaning liquid or water absorbed by the two absorbent sponges 13, which is then collected by the collection box 11. This achieves the effect of automatically cleaning the absorbent sponges 13 after the bonding wire is cleaned, avoiding the situation where the absorbent sponges 13 contain cleaning liquid or water, which would lead to poor cleaning effect of the subsequent bonding wire.
