Description

Technical Field

[0001] The present invention relates to the technical field of galvanizing equipment, and particularly to a metal surface galvanizing treatment equipment. Background Art

[0002] A semiconductor wafer, also often referred to as a silicon wafer or chip, refers to a material whose electrical conductivity at room temperature is between that of a conductor and an insulator. A semiconductor wafer is a core component of integrated circuits, electronic devices, and microelectronic devices. Semiconductors have a wide range of applications in the market and are also crucial basic materials in modern electronics industry for manufacturing various electronic devices, especially integrated circuits. A semiconductor wafer is a thin slice made of semiconductor materials (the most common being silicon, and there are also other compound semiconductors such as gallium arsenide, silicon carbide, etc.), and has electrical conductivity characteristics between those of a conductor and an insulator.

[0003] When in use, a semiconductor wafer is generally accommodated in a semiconductor package to protect the semiconductor wafer from harmful environments. The package needs to meet requirements such as corrosion resistance and wear resistance. For such a package, existing packages can be subjected to hot-dip plating, immersing the package in a hot-dip plating solution for galvanizing to meet the corrosion resistance and wear resistance requirements of the package. However, when the package is galvanized, the clamped part of the package cannot be galvanized under the traditional clamping method, which destroys the aesthetics and corrosion resistance of the package.

Specific embodiments

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Embodiment:

[0042] Please refer to Figures 10 - 12 , the present invention provides a technical solution: a metal surface galvanizing treatment device, including a mounting frame 1 and a galvanizing tank 2. The galvanizing tank 2 is installed on the mounting frame 1. A heating element 6 is arranged in the galvanizing tank 2, and galvanizing liquid is provided in the galvanizing tank 2. The heating element 6 heats the galvanizing liquid in the galvanizing tank 2 to facilitate maintaining the temperature of the galvanizing liquid and making the galvanizing liquid adhere to the surface of the galvanized part more quickly. A first lead screw 10 is movably installed between the tops of the mounting frame 1, and a power motor is arranged at one end of the first lead screw 10. A connecting cylinder 5 is threadedly connected to the outside of the first lead screw 10. The bottom end of the connecting cylinder 5 is fixedly installed with a connecting frame 8 through a telescopic column 15. Clamping frames 9 are movably installed on both sides of the bottom end of the connecting frame 8. The clamping frames 9 can slide at the bottom end of the connecting frame 8, and a sealing ring is arranged at the sliding connection between the clamping frames 9 and the connecting frame 8. A galvanized part 7 is clamped between two adjacent clamping frames 9. A clamping and replacing mechanism is arranged in the clamping frames 9. The clamping and replacing mechanism replaces the clamping method of the galvanized part 7 after the galvanized part 7 enters the galvanizing tank 2 to ensure that each position on the surface of the galvanized part 7 can be galvanized.

[0043] In this embodiment, the clamping and replacement mechanism includes an abutting block 33 and a clamping plate 34. Both the abutting block 33 and the clamping plate 34 are in contact with the surface of the galvanized part 7. The abutting block 33 is in contact with the side of the galvanized part 7, and the clamping plate 34 is in contact with the upper and lower surfaces of the galvanized part 7. When the abutting block 33 is in contact with the galvanized part 7, two adjacent abutting blocks 33 are respectively located on both sides of the galvanized part 7, and the two adjacent abutting blocks 33 will fix the galvanized part 7 by mutual extrusion. Clamping plates 34 are arranged on both sides of each abutting block 33. When the abutting block 33 is separated from the galvanized part 7, the clamping plate 34 will be in contact with the upper and lower parts of the galvanized part 7, that is, the clamping plate 34 will form a C-shaped guide rail to clamp the galvanized part 7, ensuring that the part of the galvanized part 7 blocked by the abutting block 33 during galvanizing will be galvanized, ensuring that there are no impurity points on the surface of the galvanized part 7, and ensuring that the surface of the galvanized part 7 is fully galvanized.

[0044] In this embodiment, a third inclined panel 29 is movably installed on the inner bottom wall of the connecting frame 8. A fourth inclined panel 32 and a second rack column 37 are respectively movably installed in the clamping frame 9. The second rack column 37 is slidably connected to the inner wall of the clamping frame 9. The second rack column 37 slides on the inner wall of the clamping frame 9 and slides through the second limiting column to ensure that the second rack column 37 is in a linear motion state. The third inclined panel 29 and the fourth inclined panel 32 are in sliding contact through the inclined surface. When the third inclined panel 29 moves, it drives the fourth inclined panel 32 to slide on the first limiting column in the clamping frame 9 through the inclined surface to keep the sliding direction fixed. One end of the fourth inclined panel 32 is fixedly installed with a first rack column 35. The other end of the first rack column 35 is fixedly installed with a second connecting rod 38. The other end of the second connecting rod 38 is fixedly connected to the clamping plate 34. One end of the second rack column 37 is fixedly installed with the abutting block 33. Sealing rings are arranged in the through holes of the second rack column 37 and the second connecting rod 38 passing through the clamping frame 9 to ensure that no galvanizing liquid enters the clamping frame 9 when the abutting block 33 and the clamping plate 34 move.

[0045] In this embodiment, a second rotating gear 36, a first limiting column and a second limiting column are respectively fixedly installed in the clamping frame 9. The first rack column 35 and the second rack column 37 are respectively located on both sides of the second rotating gear 36, and both the first rack column 35 and the second rack column 37 are meshed with the second rotating gear 36. The fourth inclined panel 32 is located outside the first limiting column, and the second rack column 37 is located outside the second limiting column.

[0046] A receiving cavity is formed on one side of the clamping frame 9 close to the galvanized part 7. Both the abutting block 33 and the clamping plate 34 are located in the receiving cavity, and the abutting block 33 and the clamping plate 34 are staggeredly distributed in the receiving cavity.

[0047] During use, when the third inclined panel 29 moves towards the galvanized part 7, the third inclined panel 29 will drive the fourth inclined panel 32 to move towards the galvanized part 7 together. When the fourth inclined panel 32 moves, it will drive the first rack column 35 to move in the clamping frame 9. The first rack column 35 is meshed and connected with the second rotating gear 36, and the second rotating gear 36 is also meshed and connected with the second rack column 37. The first rack column 35 and the second rack column 37 are respectively located on both sides of the second rotating gear 36. In this way, when the first rack column 35 moves, it will drive the second rack column 37 to move together through the second rotating gear 36, and the moving directions of the first rack column 35 and the second rack column 37 are opposite. When the first rack column 35 moves, it will drive the clamping plate 34 to extend out of the accommodation cavity of the clamping frame 9 through the second connecting rod 38 and extend to the upper and lower surfaces of the galvanized part 7 to clamp the galvanized part 7. As the first rack column 35 moves, the second rack column 37 will drive the abutting block 33 to retract into the accommodation cavity of the clamping frame 9 and separate from the side of the galvanized part 7. In this way, after the galvanized part 7 enters the galvanizing bath 2, as the galvanized part 7 moves in the galvanizing bath 2, the clamping method of the galvanized part 7 changes. In this way, after the galvanized part 7 enters the galvanizing bath 2, with the change of the clamping method, the surface of the galvanized part 7 will be fully galvanized, that is, the contact part between the galvanized part 7 and the abutting block 33 at the beginning will also be galvanized, increasing the aesthetics of the galvanized part 7 and increasing the corrosion resistance of the galvanized part 7.

[0048] Please refer to Figures 1 - 9 In this embodiment, a fixing plate 3 is fixedly installed on the mounting frame 1. The fixing plate 3 is located on the side of the first lead screw 10. First inclined surfaces 12 are provided on both sides of the fixing plate 3. A tooth block portion 17 is fixedly installed at the bottom end of the fixing plate 3. A first movable block 18 is movably installed inside the connecting cylinder 5. A telescopic column 15 and a first compression spring 19 are respectively fixedly installed at the bottom end of the first movable block 18. The first compression spring 19 is sleeved on the outside of the telescopic column 15. The bottom end of the telescopic column 15 penetrates through the inner wall of the bottom end of the connecting cylinder 5 and is fixedly connected to the top end of the connecting frame 8. When the telescopic column 15 moves downward, it will drive the first movable block 18 to move downward through the first movable block 18 and squeeze the first compression spring 19, providing a power source for the first movable block 18 to move upward when the pressure of the fixing plate 3 on the first movable block 18 and the first inclined panel 13 is lost.

[0049] In this embodiment, a first inclined panel 13 is fixedly installed on the side of the first movable block 18. The first inclined panel 13 is in sliding contact with the first inclined surface 12. A connecting column 14 is fixedly installed at the bottom end of the first inclined panel 13. A first rotating gear 16 is movably installed between two adjacent connecting columns 14. The end of the first rotating gear 16 is movably connected to a transmission belt 20. The first rotating gear 16 is meshed with the tooth block portion 17. When the connecting cylinder 5 moves on the first lead screw 10, the first inclined panel 13 on the side of the connecting cylinder 5 will contact the first inclined surface 12 of the fixed plate 3. As the connecting cylinder 5 continues to move, the first inclined panel 13 will slide downward along the first inclined surface 12 and drive the connecting column 14 to move downward together. Until the first inclined panel 13 moves to the lower part of the fixed plate 3, the first rotating gear 16 between the two connecting columns 14 will be meshed with the tooth block portion 17 under the fixed plate 3, and at the same time, the first rotating gear 16 will also rotate simultaneously.

[0050] In this embodiment, a first rotating column 22 is movably installed in the connecting frame 8. A transmission block 24 is fixedly installed on the outer side of the first rotating column 22. The outer side of the transmission block 24 is movably connected to the transmission belt 20. When the first rotating gear 16 rotates, it will drive the transmission belt 20 in the connecting column 14 to rotate together, and drive the first rotating column 22 in the connecting frame 8 to rotate together through the transmission block 24. Second lead screws 23 are fixedly installed at both ends of the first rotating column 22. A third movable block 26 is threadedly connected to the outer side of the second lead screw 23. A pushing column 27 is fixedly installed at the bottom end of the third movable block 26. The bottom end of the pushing column 27 contacts the top end of the third inclined panel 29. When the first rotating column 22 rotates, it will drive the second lead screw 23 to rotate simultaneously. When the second lead screw 23 rotates, it moves through the third movable block 26. When the third movable block 26 moves, it will drive the pushing column 27 to move. When the pushing column 27 moves, it will drive the fourth inclined panel 32 to move through the third connecting rod 40 and the third inclined panel 29, so as to provide power for the clamping and replacing mechanism.

[0051] Please refer to Figure 9 、 Figure 13 、 Figure 14, the present invention provides a technical solution: In this embodiment, a guide post 30 is fixedly installed on the inner wall of the connection frame 8. A second movable block 25 and a second compression spring 31 are respectively movably installed on the outer side of the guide post 30. One end of the second compression spring 31 is fixedly connected to the second movable block 25, and the other end is fixedly connected to the inner wall of the connection frame 8. One end of the second movable block 25 is fixedly installed with a first connecting rod 21, and the first connecting rod 21 passes through the inner wall of the connection frame 8 and is fixedly connected to the side of the clamping frame 9. A sealing gasket is provided in the through groove of the connection frame 8 that matches the penetration of the first connecting rod 21. When the clamping frame 9 is separated from the galvanized part 7, the clamping frame 9 will move below the connection frame 8. When the clamping frame 9 moves, it will drive the second movable block 25 to move in the connection frame 8 through the first connecting rod 21. The second movable block 25 slides on the guide post 30 and will squeeze the second compression spring 31 to keep the clamping frame 9 movable.

[0052] In this embodiment, a fourth movable block 39 is movably installed inside the push post 27. A third compression spring 41 is fixedly installed on the side of the fourth movable block 39. A third connecting rod 40 is fixedly installed at the bottom end of the fourth movable block 39. A sliding through hole 43 matching the third connecting rod 40 is penetrated and opened on the inner wall of the push post 27. The third connecting rod 40 is fixedly connected to the top end of the third inclined panel 29 through the sliding through hole 43. The third movable block 26 is located inside the second movable block 25. A limiting rod 42 is fixedly installed on the side of the second movable block 25, and the limiting rod 42 contacts the side of the fourth movable block 39.

[0053] In this embodiment, a second inclined panel 28 is fixedly installed on the side of the clamping frame 9 close to the abutting block 33 and the clamping plate 34. The conveying mechanism 4 includes a discharging post 11. The discharging post 11 is located above the galvanized part 7. The second inclined panel 28 and the discharging post 11 are slidably connected through an inclined surface. The discharging post 11 can separate the clamping frame 9 from the galvanized part 7 through the second inclined panel 28, which is convenient for quickly discharging the galvanized part 7 by the conveying mechanism 4 and the clamping frame 9. At the same time, it is also convenient for quickly loading the galvanized part 7 by the conveying mechanism 4 and the clamping frame 9.

[0054] When the unloading column 11 contacts the second inclined panel 28, the unloading column 11 will drive the clamping frame 9 to move below the connecting frame 8 through the second inclined panel 28. The clamping and replacement mechanism on the clamping frame 9 will separate from the galvanized part 7. When the clamping frame 9 moves, it will drive the second movable block 25 to slide on the guide post 30 through the first connecting rod 21. When the second movable block 25 slides, it will drive the limit rod 42 to move together, so that the limit rod 42 separates from the fourth movable block 39. As the clamping frame 9 moves, the fourth inclined panel 32 inside the clamping frame 9 moves together. When the fourth inclined panel 32 moves, it will drive the third inclined panel 29 to move together. When the third inclined panel 29 moves, it will drive the third connecting rod 40 to move between the inner wall of the bottom end of the connecting frame 8 and the inner wall of the top end of the clamping frame 9. The third connecting rod 40 will move in the sliding through hole 43, ensuring that the clamping frame 9 will not be blocked by the third inclined panel 29 when moving. At the same time, it also ensures that as the unloading column 11 contacts the second inclined panel 28, the clamping frame 9 can be separated from the galvanized part 7, so that the galvanized part 7 can be passively unloaded under the cooperation of the unloading column 11 and the second inclined panel 28.

[0055] After the connecting cylinder 5 drives the galvanized part 7 to move to the unloading position, the galvanized part 7 on the clamping frame 9 will be unloaded. Since the first lead screw 10 is a reciprocating lead screw, after the galvanized part 7 on the clamping frame 9 is unloaded, the clamping frame 9 will return to the loading position of the conveying mechanism 4 with the rotation of the first lead screw 10. The same as the unloading position of the conveying mechanism 4, when the clamping frame 9 moves to the loading position of the conveying mechanism 4, it will also contact the unloading column 11 at the loading position and make the clamping frame 9 on both sides of the waiting galvanized part 7. Again, with the rotation of the first lead screw 10 working, the connecting cylinder 5 will drive the clamping frame 9 to move toward the galvanizing bath 2 side through the connecting frame 8. During the movement, the second inclined panel 28 on the clamping frame 9 will gradually separate from the unloading column 11, and the adjacent two clamping frames 9 will also approach each other, so as to complete the clamping and fixing of the galvanized part 7 through the abutting block 33, and then drive the galvanized part 7 into the galvanizing bath 2 for galvanizing treatment.

[0056] As the clamping frame 9 moves, the fourth inclined panel 32 inside it will also move together. The third inclined panel 29 contacts the fourth inclined panel 32 through the inclined surface. Similarly, the extrusion of the third compression spring 41 caused by the third inclined panel 29 before will disappear, and the third compression spring 41 will release the pressure, driving the fourth movable block 39 to slide in the pushing column 27. The fourth movable block 39 drives the third inclined panel 29 to slide through the sliding through hole 43 and the third connecting rod 40, preventing the clamping frame 9 from being unable to perform the clamping work.

[0057] The rotation of the first lead screw drives the connecting cylinder to move, realizing the automatic entry and exit of the galvanized part into and out of the galvanizing bath. During the movement, the linkage cooperation between the various components realizes the automatic switching of the clamping method and the automatic operation of unloading and loading, improving the production efficiency and reducing the manual operation.

[0058] Working principle of this embodiment: During use, the galvanized part 7 is clamped by two adjacent clamping frames 9. Through the operation of the first lead screw 10, the first lead screw 10 will drive the connecting cylinder 5 to move towards the fixed plate 3. When the connecting cylinder 5 moves, the first inclined panel 13 on its side will come into contact with the first inclined surface 12 on the side of the fixed plate 3, and the first inclined panel 13 will slide on the first inclined surface 12. When the first inclined panel 13 slides down, it will drive the first movable block 18 in the connecting cylinder 5 to move downward. The first movable block 18 moving downward will drive the galvanized part 7 to move into the galvanizing bath 2 together through the telescopic column 15, connecting frame 8 and the abutting block 33 of the clamping frame 9. As the first lead screw 10 rotates, the first inclined panel 13 will move uniformly to the bottom of the first inclined surface 12, and then the first rotating gear 16 below the first inclined panel 13 will be meshed and connected with the tooth block part 17 below the fixed plate 3. At the same time, the galvanized part 7 will also carry out galvanizing work in the galvanizing bath 2. When the connecting cylinder 5 continues to move along with the first lead screw 10, the first rotating gear 16 will rotate through the tooth block part 17. When the first rotating gear 16 rotates, it will drive the first rotating column 22 to rotate through the transmission belt 20 and the transmission block 24. When the first rotating column 22 rotates, it will drive the second lead screw 23 to rotate. When the second lead screw 23 rotates, it will drive the push column 27 to move towards the galvanized part 7 through the third movable block 26. When the push column 27 moves, it will drive the fourth inclined panel 32 to move in the clamping frame 9 through the third inclined panel 29. When the fourth inclined panel 32 moves, it will drive the clamping plate 34 to extend out of the receiving cavity through the first rack column 35 and the second connecting rod 38, and come into contact with the upper and lower surfaces of the galvanized part 7. At the same time, during the movement of the first rack column 35, it will drive the second rack column 37 to drive the abutting block 33 to retract into the receiving cavity through the second rotating gear 36, and separate from the side of the galvanized part 7. In this way, the parts of the surface of the galvanized part 7 covered by the abutting block 33 will also be galvanized, increasing the aesthetics of the galvanized part 7 and its corrosion resistance. As the connecting cylinder 5 continues to move on the first lead screw 10, at the same time, the clamping frame 9 will also drive the galvanized part 7 to move in the galvanizing bath 2. The galvanized part 7 will carry out galvanizing work in the galvanizing bath 2, and the movement of the galvanized part 7 along with the clamping frame 9 will cause the galvanizing solution in the galvanizing bath 2 to flow, ensuring that the temperatures of the galvanizing solutions at different depths in the galvanizing bath 2 are balanced. As the connecting cylinder 5 continues to move, the first inclined panel 13 will come into contact with the first inclined surface 12 on the other side of the fixed plate 3 and move upward through the first inclined surface 12. Through the release of the pressure of the first compression spring 19 in the connecting cylinder 5, the first movable block 18 will drive the telescopic column 15 to retract into the connecting cylinder 5, and drive the connecting frame 8, clamping frame 9 and galvanized part 7 to be taken out of the galvanizing bath 2 together, completing the galvanizing work of the galvanized part 7. And with the cooperation of the unloading column 11 and the second inclined panel 28, the clamping frame 9 will passively unload the galvanized part 7.
