Description

Technical Field

[0001] The invention relates to the technical field of copper foil anti-corrosion spraying equipment, in particular to a copper foil surface coating treatment device for lead frame processing. Background Art

[0002] In modern electronics manufacturing, lead frames serve as a critical support structure for electronic components, and their performance is crucial to the stability and reliability of these devices. Copper foil, due to its excellent electrical and thermal conductivity and good mechanical properties, is a common material for lead frame manufacturing. However, during processing and use, copper foil is susceptible to environmental erosion, leading to oxidation and corrosion, which in turn affect the electrical performance and service life of the lead frame. Therefore, coating the copper foil surface to enhance its corrosion resistance has become a key step in lead frame processing.

[0003] Currently, existing copper foil surface coating treatment devices have many limitations in practical applications. In terms of spraying efficiency, most traditional equipment can only achieve single-sided spraying. To complete double-sided spraying, manual flipping or the use of complex multi-station conversion mechanisms are required. This not only increases the operating procedures and time costs, but also easily leads to production interruptions, making it difficult to meet the needs of large-scale, high-efficiency production. In the drying process, some equipment lacks specialized drying devices and relies on natural drying, which is extremely inefficient. Even equipment with drying functions mostly uses a simple hot air direct blowing method, which is uneven and easily causes the copper foil to be contaminated by impurities such as dust before the coating is dry, affecting the coating quality.

[0036] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific operations are as follows.

[0037] S1. First, after powering on the equipment, the copper foil being produced or being wound is fed from the first guide roller 14 on the first roller frame 13 at the top right end of the spray box 11, i.e., it is fed from the right end of the spray box 11 to the left. The third roller frame 182 in the pressing assembly 18 is manually lifted, and the lower pressing roller 183 is raised and raised by the limit seat 181, so that the lower pressing roller 183 is pressed on top of the copper foil, and the copper foil is pressed downward to a limited position. The lower pressing roller 183 is forced down and pressed by the spring 185 on the force rod 184;

[0038] S2. Next, the copper foil passes over the first guide roller 14 at the top left end of the spray box 11 and is guided downward to the first guide roller 14 below. It is then guided rightward through one of the conveying ports into the spray box 11. It is then guided downward through the second guide roller 15 corresponding to the right side of the first conveying port to another second guide roller 15. Finally, it is guided leftward through another second guide roller 15, passes through another conveying port and the corresponding first guide roller 14, and is then conveyed by the third guide roller 17 on the second roller frame 16. This conveyance is achieved from right to left, and the copper foil is turned over through the reciprocating left and right guidance.

[0039] S3. The material pump 33 in the spray structure 3 is then connected to the feed end to extract the spray material and supply it to the second diverter 34 for diversion to the corresponding nozzles 366 for spraying. With the help of the concave spray rack 31, the spray assembly 36 is symmetrically arranged at both ends to achieve double-sided spraying of the guided copper foil;

[0040] S4 copper foil into the spray box 11 on the wall of one of the spraying, into the spray box 11 to the right when the other side of the spraying process;

[0041] S5. After the sprayed copper foil is transported with the help of a guide, the sprayed wall surfaces are respectively opposite to the first diverter 22 on the corresponding support plate 21, and then heated by means of a bellows 23, and hot air is delivered by means of a fan 24, and finally blown through the first diverter 22 to achieve a certain width for drying;

[0042] S6. During the copper foil processing, the motor 363 can be controlled as needed to drive one of the shaft tubes 361 to rotate in the bearing 32. The gears 362 on the shaft tube 361 engage with each other, thereby achieving synchronous and opposite rotation of the two gears 362. This drives the relatively arranged swing arms 364 to flip relative to each other or flip in the opposite direction. As the angle of the swing arms 364 changes, the spraying position and spraying width range of the nozzle 366 on the second socket 365 are adjusted; and the nozzle 366 installed through the first socket 35 is located between the swing arms 364 to fill the gap between the swing arms 364. Figure 11 The spray range shown is demonstrated;

[0043] S7. Since the second socket 365 and the second socket 365 can be moved in the second slot 5 and the first slot 4 to adjust the position and the spraying spacing respectively, the nozzle 366 can be docked or staggered in the spraying range to prevent leakage, and can be fixed by tightening the bolt 6 after moving.
