Description

Technical Field

[0001] This invention relates to the field of copper foil production technology, specifically to an anti-oxidation surface treatment device for copper foil production. Background Technology

[0002] Copper foil is a cathodic electrolytic material, a thin, continuous metal foil deposited on the substrate layer of a circuit board. Because it easily adheres to the insulating layer, accepts the printed protective layer, and forms circuit patterns after etching, it is mainly used as a conductor in PCBs. To prevent the copper foil from oxidizing after production, workers need to use anti-oxidation devices to prevent oxidation of the copper foil.

[0003] When copper foil cut into square pieces needs to be protected against oxidation, workers need to use pliers to place the copper foil in a storage box soaked in a treatment agent. The treatment agent then forms a protective film on the surface of the copper foil, ensuring that the copper foil does not meet the usage requirements due to surface oxidation during storage and transportation.

[0004] The existing technology has at least the following problems: When clamping copper foil with clamping pliers, in order to prevent the copper foil from falling, the clamping pliers will be in close contact with the copper foil. During the soaking process, the part of the clamping pliers in contact with the copper foil will not be protected, and the workers will need to perform anti-oxidation work on the part of the copper foil that has not been removed, which reduces the efficiency of the workers. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a copper foil production anti-oxidation surface treatment device, comprising a storage box, two outer frames arranged vertically inside the storage box, the lower outer frame being connected to the inner sidewall of the bottom of the storage box via a reset assembly, a positioning mechanism being installed inside each of the two outer frames, a driving mechanism being installed on the front surface of the outer frame and inside the storage box, and a filtering mechanism being installed at both ends of the inner sidewall of the storage box.

[0006] The positioning mechanism includes positioning plates. Positioning plates are installed on the opposite sides of the two outer frames. Several sets of positioning rods are arranged from left to right inside the positioning plates, with four positioning rods in each set. A longitudinal rod is installed on the top of each positioning rod, and each positioning rod is slidably connected to the positioning plate. A first inclined plate is slidably connected to each set of positioning rods arranged in an odd number from left to right. Several first inclined plates are connected to each other through a first extension plate. A second inclined plate is slidably connected to each set of positioning rods arranged in an even number from left to right. Several second inclined plates are connected to each other through a second extension plate. A fixing frame is installed on the front surface of both the second and first extension plates. A third spring frame is installed at the end of each of the first and second inclined plates away from the fixing frame. The other end of the third spring frame is connected to the rear of the inner wall of the outer frame. A strip groove is opened inside the positioning plate and on one side of the second inclined plate. A stirring component is installed inside the strip groove.

[0007] Preferably, the filtration mechanism includes a left sealing gasket, a pusher, a baffle, a filter screen, a second spring frame, a right sealing gasket, and a third cam. The left sealing gasket is slidably connected to the left side of the inner wall of the storage box. A support rod is slidably connected to the left side of the left sealing gasket. The support rod is fixedly connected to the inner wall of the storage box. A second spring frame fitted on the support rod is installed between the left end of the left sealing gasket and the left inner wall of the outer frame. A pusher is installed at the right end of the left sealing gasket. A third cam is rotatably connected at the middle of the bottom of the storage box. The right sealing gasket is slidably connected to the right side of the inner wall of the storage box. A baffle is installed on the left side of the right sealing gasket. The baffle is fixedly connected to the storage box. A filter screen is installed below the right end of the baffle. A check valve is installed below the inside of the baffle.

[0008] Preferably, the drive mechanism includes a first cam, a rotating frame, a second cam, and a rotating rod. A rotating rod is rotatably mounted inside the front of the storage box. Two rotating frames are slidably mounted on the outer side wall of the rotating rod. The rotating frames are connected to the outer frame through brackets. The brackets are fixedly connected to the front surface of the outer frame and rotatably connected to the outer side wall of the rotating frames. The outer side wall of the rotating frames also has a first cam and a second cam arranged vertically.

[0009] Preferably, the reset assembly includes a first spring frame, a slide rod, and an outer block. The outer blocks are installed at both ends of the lowermost outer frame. The slide rod is slidably connected to the inner sidewall of the outer block. The bottom of the slide rod is fixedly connected to the storage box. The first spring frame, sleeved on the outer sidewall of the slide rod, is installed between the slide rod and the inner sidewall of the storage box.

[0010] Preferably, the stirring assembly includes a stirring wheel, a toothed disc, and a rack. The stirring wheel is rotatably connected inside the strip groove. The toothed disc is installed at the left end of the stirring wheel. The rack is meshed with the bottom of the toothed disc. The rack is fixedly connected to the second extension plate.

[0011] Preferably, the check valve includes a water pipe, a sealing plate, and a magnet. The water pipe is installed inside the lower part of the baffle, the sealing plate is rotatably installed at the left end of the water pipe, and the magnet is installed below the left end of the water pipe.

[0012] Preferably, a sealing block is installed above the left end of the right sealing gasket.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. With the cooperation of the driving mechanism, the longitudinal rod inside the positioning mechanism can alternately contact the square copper foil sheet. In this way, the square copper foil sheet can be clamped and contacted with the soaking liquid in all directions, avoiding the step of soaking the square copper foil sheet twice and increasing the efficiency of the workers.

[0014] 2. As the second inclined plate moves back and forth, the rack will drive the toothed disc to rotate, and then the toothed disc will drive the stirring wheel to rotate. The stirring wheel can make the soaking solution flow, so that the treatment agent in the soaking solution can fully contact the copper foil, increasing the anti-oxidation efficiency.

[0015] 3. As the rotating rod rotates, the left sealing gasket moves to the right via the second spring frame. This allows the soaking solution to flow, ensuring that the treatment agent in the soaking solution can fully contact the copper foil. During this process, the treatment agent can be filtered through the filter screen to prevent impurities from contacting the square copper foil sheet. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 scope of protection of the present invention.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, a copper foil production anti-oxidation surface treatment device includes a storage box 1. Inside the storage box 1, two outer frames 2 are arranged vertically. The lower outer frame 2 is connected to the bottom inner wall of the storage box 1 through a reset component 21. Positioning mechanisms 3 are installed inside both outer frames 2. A drive mechanism 4 is installed on the front surface of the outer frame 2 inside the storage box 1. Filtering mechanisms 5 are installed at both ends of the inner wall of the storage box 1.

[0030] In practice, the upper outer frame 2 is connected to the external hydraulic telescopic rod. Then, the square copper foil sheet is placed between the two outer frames 2. The upper outer frame 2 can be moved downward by the external hydraulic telescopic rod. During this process, the two outer frames 2 squeeze the square copper foil sheet while moving it into the storage box 1. Then, the drive mechanism 4 can make the positioning mechanism 3 inside the outer frame 2 circulate and intermittently contact the square copper foil sheet. In this way, the square copper foil sheet can fully contact the soaking liquid inside the storage box 1, ensuring more thorough anti-oxidation. During this process, the filtration mechanism 5 can make the soaking liquid inside the storage box 1 shake while filtering the soaking liquid to prevent impurities from remaining in the soaking liquid.

[0031] like Figure 5 , Figure 6 and Figure 7 As shown, the positioning mechanism 3 includes a positioning plate 31. Positioning plates 31 are installed on the opposite faces of the two outer frames 2. Several sets of positioning rods 32 are arranged sequentially from left to right inside the positioning plate 31, with four rods in each set. A vertical rod 321 is installed on the top of each positioning rod 32, and each positioning rod 32 is slidably connected to the positioning plate 31 vertically. Each set of positioning rods 32, arranged in an odd number from left to right, is slidably connected to a first inclined plate 33. Several first inclined plates 33 are connected by a first extension plate 331. Each set of positioning rods 32, arranged in an even number from left to right... Each of the positioning rods 32 is slidably connected with a second inclined plate 37. Several second inclined plates 37 are connected by a second extension plate 371. The front surfaces of the second extension plate 371 and the first extension plate 331 are both equipped with a fixing frame 34. The ends of the first inclined plate 33 and the second inclined plate 37 away from the fixing frame 34 are both equipped with a third spring frame 36. The other end of the third spring frame 36 is connected to the rear of the inner wall of the outer frame 2. A strip groove 311 is opened inside the positioning plate 31 and on one side of the second inclined plate 37. A stirring assembly 35 is installed inside the strip groove 311.

[0032] like Figure 4 , Figure 9 and Figure 10 As shown, the drive mechanism 4 includes a first cam 41, a rotating frame 42, a second cam 43, and a rotating rod 44. The rotating rod 44 is rotatably installed inside the front of the storage box 1. Two rotating frames 42 are slidably installed on the outer side wall of the rotating rod 44. The rotating frame 42 is connected to the outer frame 2 through a bracket 45. The bracket 45 is fixedly connected to the front surface of the outer frame 2. The bracket 45 is rotatably connected to the outer side wall of the rotating frame 42. The outer side wall of the rotating frame 42 also has a first cam 41 and a second cam 43 arranged vertically.

[0033] In actual operation, the bottom of the rotating rod 44 is connected to an external motor. The external motor drives the first cam 41 and the second cam 43 on the outer side wall of the rotating rod 44 to rotate. Since the first cam 41 and the second cam 43 are staggered, when the first cam 41 pushes the first inclined plate 33 to the rear, the second cam 43 will release its constraint from the second inclined plate 37. Then, with the cooperation of the third spring bracket 36, the second inclined plate 37 will slide forward. Since both the first inclined plate 33 and the second inclined plate 37 are slidably connected to the inclined groove of the positioning rod 32, the first inclined plate 33 can push the longitudinal rod 3 connected to the positioning rod 32. While clamping the square copper foil pieces, the corresponding vertical rod 321 of the second inclined plate 37 can release the clamping of the square copper foil pieces. As the first cam 41 and the second cam 43 rotate cyclically, the vertical rod 321 alternately contacts the square copper foil pieces, allowing the square copper foil pieces to be in contact with the soaking liquid from all directions. When the outer frame 2 moves up and down, it will drive the first cam 41 and the second cam 43 to move up and down synchronously. This allows the first cam 41 and the second cam 43 to constrain the first inclined plate 33 and the second inclined plate 37, preventing the third spring frame 36 from pushing the first inclined plate 33 and the second inclined plate 37 to slide forward.

[0034] like Figure 4 As shown, the reset assembly 21 includes a first spring frame 211, a slide rod 212, and an outer block 213. The lowermost outer frame 2 has outer blocks 213 installed at both ends below it. The slide rod 212 is slidably connected to the inner wall of the outer block 213. The bottom of the slide rod 212 is fixedly connected to the storage box 1. A first spring frame 211 is installed between the slide rod 212 and the inner wall of the storage box 1, sleeved on the outer wall of the slide rod 212. In operation, initially, the first spring frame 211 supports the lowermost outer frame 2, ensuring it is positioned above the storage box 1. When the uppermost outer frame 2 pushes the lower outer frame 2 downwards, the first spring frame 211 is compressed. When the uppermost outer frame 2 releases its downward force on the lower outer frame 2, the first spring frame 211 moves the lower outer frame 2 back to its initial position during the reset process. This ensures normal operation during the next operation.

[0035] like Figure 5 and Figure 8As shown, the stirring assembly 35 includes a stirring wheel 351, a toothed disc 352, and a rack 353. The stirring wheel 351 is rotatably connected inside the strip groove 311. The toothed disc 352 is installed at the left end of the stirring wheel 351. The rack 353 is meshed and connected below the toothed disc 352. The rack 353 is fixedly connected to the second extension plate 371. In specific operation, as the second inclined plate 37 moves back and forth, the rack 353 drives the toothed disc 352 to rotate. Then, the toothed disc 352 drives the stirring wheel 351 to rotate. The stirring wheel 351 can make the soaking solution flow, so that the treatment agent in the soaking solution can fully contact the copper foil, increasing the anti-oxidation efficiency.

[0036] like Figure 2 and Figure 3 As shown, the filtration mechanism 5 includes a left sealing gasket 51, a pusher 52, a baffle 53, a filter screen 54, a second spring frame 55, a right sealing gasket 56, and a third cam 57. The left sealing gasket 51 is slidably connected to the left side of the inner wall of the storage box 1. A support rod is slidably connected to the left side of the left sealing gasket 51. The support rod is fixedly connected to the inner wall of the storage box 1. A second spring frame 55, sleeved on the support rod, is installed between the left end of the left sealing gasket 51 and the left inner wall of the outer frame 2. A pusher 52 is installed at the right end of the left sealing gasket 51. A third cam 57 is rotatably connected to the middle position of the bottom of the storage box 1. The third cam 57 is connected to the rotating rod 44 via a belt. The right sealing gasket 56 is slidably connected to the right side of the inner wall of the storage box 1. A baffle 53 is installed on the left side of the right sealing gasket 56. The baffle 53 is fixedly connected to the storage box 1. A filter screen 54 is installed below the right end of the baffle 53. A check valve 531 is installed inside the lower part of the baffle 53.

[0037] In actual operation, while the rotating rod 44 rotates, the third cam 57 rotates via the belt. The third cam 57 pushes the left sealing gasket 51 to the left. When the third cam 57 releases the constraint on the left sealing gasket 51, the second spring frame 55 pushes the left sealing gasket 51 to the right while resetting. This allows the soaking liquid to flow. During the movement of the left sealing gasket 51 to the right, the volume of the storage box 1 decreases, and the soaking liquid inside the storage box 1 becomes higher than the baffle 53. The soaking liquid then flows from the left side of the baffle 53 to the right side, connecting the right sealing gasket 56 to the external electric push rod. The external electric push rod allows the right sealing gasket 56 to move left and right. During the movement of the right sealing gasket 56 to the left, the soaking liquid between the baffle 53 and the inner wall of the storage box 1 is processed by the filter screen 54 and flows out from the check valve 531. This filters the soaking liquid and prevents impurities from contacting the copper foil square sheet.

[0038] like Figure 11As shown, the check valve 531 includes a water pipe 5311, a sealing plate 5312, and a magnet 5313. The water pipe 5311 is installed inside the lower part of the baffle 53. The sealing plate 5312 is rotatably installed on the left end of the water pipe 5311, and the magnet 5313 is installed below the left end of the water pipe 5311. In actual operation, when the water pipe 5311 flows from right to left, the sealing plate 5312 will open under the action of water resistance. When the water pipe 5311 stops flowing from right to left, the sealing plate 5312 will block the left end of the water pipe 5311 under the action of gravity. At the same time, the magnet 5313 will make the connection between the sealing plate 5312 and the water pipe 5311 tighter, preventing water backflow.

[0039] like Figure 2 As shown, a sealing block 532 is installed on the upper left end of the right sealing gasket 56. During operation, as the right sealing gasket 56 moves to the left, the sealing block 532 will block the baffle 53 to prevent the soaking liquid from flowing out from above the baffle 53.

[0040] Working principle of this invention: When this processing device is in use:

[0041] Step 1: Place the square copper foil sheet between the two outer frames 2. The upper outer frame 2 can be moved downward by the external hydraulic telescopic rod. During this process, the two outer frames 2 squeeze the square copper foil sheet while moving it into the storage box 1.

[0042] Step 2: An external motor can drive the first cam 41 and the second cam 43 on the outer side wall of the rotating rod 44 to rotate. During this process, the longitudinal rod 321 inside the positioning plate 31 alternately contacts the square copper foil sheet, so that the square copper foil sheet can fully contact the soaking liquid.

[0043] Step 3: As the rotating rod 44 rotates, the third cam 57 will rotate via the belt. Then, the second spring frame 55 can move the left sealing gasket 51 to the right, so that the soaking liquid is in a flowing state. During this process, the soaking liquid inside the storage box 1 will flow from the left side of the baffle 53 to the right side of the baffle 53. The right sealing gasket 56 is connected to the external electric push rod. The external electric push rod can make the soaking liquid between the baffle 53 and the inner wall of the storage box 1 flow out from the check valve 531 after being processed by the filter screen 54. In this way, the soaking liquid can be filtered.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
