Description

Technical Field

[0001] The invention relates to the technical field of cold tinning crack prevention, in particular to a tin layer crack prevention device based on cold tinning production. Background Art

[0002] Cold tinning, also commonly known as electrotinning, is a metal surface treatment technology commonly used to treat metal surfaces to achieve protective and decorative effects, corrosion resistance, electrical resistance, and dust resistance. However, when tinning a metal surface, in order to prevent the electroplated tin layer from cracking after coating, a chemical cleaning agent is usually used first to clean the metal surface to remove dirt and other impurities on the metal surface, thereby ensuring that the electroplated tin layer can firmly adhere to the metal surface.

[0003] In the process of placing metal into chemical agents for cleaning, although the chemical agents can remove dirt and other impurities on the metal surface, if the metal is placed in the chemical agents for too long and the staff does not take it out in time, the metal surface will be damaged and white spots and spots will appear. In the existing technology, when the metal cleaning time is over, the staff needs to manually take the metal out of the chemical agents. During the operation, the staff will not only make mistakes due to negligence, fatigue or other reasons, such as forgetting to take out the metal, inaccurate removal time or improper operation, these mistakes will cause the metal to stay in the chemical agents for too long, thereby causing corrosion and chemical reaction problems on the metal surface.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the present invention provides a tin layer anti-cracking device based on cold tinning production, which has the following beneficial effects:

[0019] 1. The timed ejection mechanism can automatically eject the metal from the chemical agent after the metal cleaning time is reached. This not only accurately controls the immersion time of the metal in the chemical agent, avoiding excessive immersion due to human negligence or error, thereby reducing the risk of metal damage due to corrosion or chemical reactions, but also reduces direct contact between workers and chemical agents, reducing the safety risks caused by contact with corrosive, toxic or flammable agents, thereby further improving work safety.

[0020] 2. Through the setting of the connecting plate, limit beads and spiral grooves, the rotating shaft can be automatically driven to work synchronously when the timer starts counting and the countdown ends, so that the time required for each metal cleaning batch can be accurately grasped, so as to reasonably arrange the subsequent electroplating tinning process plan for the metal surface and improve the efficiency of metal surface processing.

[0021] 3. The liquid shaking-off mechanism can automatically drive the storage frame to shake when driving the metal to rise out of the cleaning box, so as to shake off the liquid remaining on the metal surface. It can not only effectively remove the residual liquid attached to the metal surface, including solvents, impurities and reaction products, improve the cleanliness of the metal surface and ensure the quality of the metal surface, but also ensure that the metal surface is clean and free of residue, thereby ensuring the quality and stability of the subsequent electroplated tin film.

[0022] 4. By setting the connecting shaft and the movable groove opened on the outer surface of the connecting shaft, the cleaning roller can be driven synchronously to clean the metal surface while the metal is inside the cleaning box and rising out of the cleaning box. This not only ensures that the metal is fully cleaned inside the cleaning box, reduces the cleaning time, and increases the thoroughness of the cleaning, thereby improving the efficiency of the entire metal surface in the cleaning process, but also can further remove the liquid remaining on the surface of the metal after it leaves the cleaning box, ensuring that the metal surface has a better appearance and higher quality, so as to facilitate the subsequent electrotin plating process on the metal surface.

[0023] 5. Through the intermittently set cleaning rollers, the metal can be placed in the gap between the cleaning rollers in turn to maintain the distance between the metals. This can not only more accurately control the contact time and amount of the chemical agent with the metal surface, thereby ensuring the consistency of the cleaning effect, but also avoid the metals from colliding with each other during the cleaning process, resulting in scratches, indentations or damage to the metal surface, thereby maintaining the integrity of the metal surface.

[0036] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] This embodiment is a tin layer crack prevention device based on cold tinning production, such as Figure 1 - Figure 7 As shown, it includes a cleaning box 1, a storage frame 2 is arranged inside the cleaning box 1, vertical slots 5 and slide slots 6 are symmetrically opened in the cleaning box 1, and a timed ejection mechanism 3 is provided between the cleaning box 1 and the storage frame 2. The timed ejection mechanism 3 includes symmetrically arranged lifting plates 313, which are all slidably connected to the vertical slots 5. The timed ejection mechanism 3 is used to automatically push the storage frame 2 out of the cleaning box 1 after the time is reached.

[0038] In this embodiment, Figure 2 As shown, the timing ejection mechanism 3 also includes a support plate 301, the upper end surface of the support plate 301 is fixedly connected to the timer 304, the upper end surface of the timer 304 is slidably connected to a push rod 307, and the upper end of the push rod 307 is fixedly connected to a connecting plate 308. When the countdown of the timer 304 ends, the push rod 307 can be automatically pushed out from the inside of the timer 304, thereby driving the connecting plate 308 to rise synchronously. On the contrary, when the staff presses the connecting plate 308 to push the push rod 307 to slide into the inside of the timer 304, the timer 304 can be turned on and the countdown begins.

[0039] In this embodiment, Figure 2 and Figure 6 As shown, a rotating shaft 309 passes through the end of the connecting plate 308 away from the top rod 307, and the rotating shaft 309 passes through and is rotatably connected to the support plate 301. A spiral groove 314 is provided on the outer surface of the rotating shaft 309, and a limiting bead 315 is slidably connected in the spiral groove 314. The limiting bead 315 is fixedly connected to the connecting plate 308. When the top rod 307 is raised or lowered, the limiting bead 315 can be driven to move vertically up and down synchronously through the connecting plate 308, so that the limiting bead 315 can change the position of the spiral groove 314 and slide along the path of the spiral groove 314, thereby driving the rotating shaft 309 to rotate synchronously on the support plate 301.

[0040] In this embodiment, Figure 1 and Figure 3When the cam 310 is in the unlock state, the cam 310 is in the unlock state, and the lock 301 is in the unlock state, so that the cam 310 can be unlocked and the lock 302 can be unlocked.

[0041] In this embodiment, Figure 7 As shown, the sliding column 302 is fixedly connected to the moving block 311 on the side away from the moving plate 303, and the moving blocks 311 are slidably connected in the slide groove 6. The upper end surface of the moving block 311 is rotatably connected to the lifting plate 312, and the lifting plate 312 is rotatably connected to the lower end surface of the lifting plate 313 on the side away from the moving block 311. When the sliding column 302 pushes the moving block 311 to slide in the slide groove 6, the lifting plate 313 can be pushed to rise and fall synchronously through the provided lifting plate 312.

[0042] In the prior art, workers need to manually remove the metal from the chemical agent after the metal cleaning time arrives. During the operation, workers may make mistakes due to negligence, fatigue or other reasons, such as forgetting to remove the metal, inaccurate removal time or improper operation. These mistakes will cause the metal to stay in the chemical agent for too long, thereby causing corrosion and chemical reactions on the metal surface. In addition, the chemical agents are corrosive, toxic or flammable. Workers face safety risks when contacting or operating these agents. If they accidentally come into contact with the agents, the workers may experience skin irritation, burns, poisoning or other health problems. Compared with the prior art, the metal can be automatically pushed out of the chemical agent after the metal cleaning time arrives. This not only can accurately control the immersion time of the metal in the chemical agent, avoiding excessive immersion due to human negligence or error, thereby reducing the risk of damage to the metal due to corrosion or chemical reactions, but also reduces the direct contact between workers and chemicals, reducing the safety risks caused by contact with corrosive, toxic or flammable agents, thereby further improving work safety.

[0043] In other aspects, this embodiment also provides a liquid shaking mechanism 4 for removing residual liquid from the metal surface, such as Figure 1 、 Figure 3 - Figure 5As shown, the liquid shaking mechanism 4 includes symmetrically arranged frames 404, which are fixedly connected to the side walls of the storage frame 2. A transverse groove 405 is opened on the side of the frame 404 away from the storage frame 2, and the lifting plates 313 are slidably connected to the transverse groove 405.

[0044] In this embodiment, Figure 1 and Figure 4 As shown, linkage rods 406 are fixedly connected on both sides of the frame 404, and corrugated plates 402 are provided on the side of the linkage rods 406 away from the frame 404. The corrugated plates 402 are used to limit the linkage rods 406, and the side of the corrugated plates 402 away from the linkage rods 406 is fixedly connected to vertical plates 401, and the vertical plates 401 are fixedly connected to the inner wall of the cleaning box 1. When the frame 404 rises and drives the linkage rods 406 to move upward synchronously, the linkage rods 406 on both sides will contact the corrugated plates 402 and move in accordance with the corrugations on the side walls of the corrugated plates 402. At this time, the horizontal grooves 405 opened on the side walls of the frame 404 can drive the frame 404 to move back and forth horizontally on the lifting plate 313.

[0045] In this embodiment, Figure 5 As shown, the storage frame 2 is equidistantly connected to the connecting shaft 407 for rotation. The connecting shaft 407 is sleeved with a cleaning roller 403. The outer surface of the connecting shaft 407 is provided with a movable groove 408. The cleaning roller 403 is slidably connected to the outer surface of the connecting shaft 407 through the movable groove 408. When the cleaning roller 403 is impacted by the agent, it will drive the connecting shaft 407 to rotate in the storage frame 2, so that the cleaning roller 403 rotates to clean the metal surface. Moreover, during the rising and shaking process of the storage frame 2, the movable groove 408 can drive the cleaning roller 403 to move back and forth synchronously on the surface of the connecting shaft 407 to wipe the metal surface and keep the metal surface clean.

[0046] In the prior art, after the metal is taken out from the inside of the chemical agent, some liquid will still remain on the metal surface. If this liquid is not treated, it will cause blistering, cracking or peeling of the electroplated tin layer during the subsequent electroplating of the tin film. Compared with the prior art, the storage frame 2 can be automatically driven to shake while driving the metal to rise out of the cleaning box 1, so as to shake off the liquid remaining on the metal surface. This can not only effectively remove the residual liquid attached to the metal surface, including solvents, impurities and reaction products, thereby improving the cleanliness of the metal surface and ensuring the quality of the metal surface, but also ensure that the metal surface is clean and free of residue, thereby ensuring the quality and stability of the subsequent electroplated tin film.

[0047] The working process and principles involved in the overall content of the above embodiment are as follows:

[0048] When the staff is placing the metal in the storage frame 2 for cleaning, when the timer 304 expires, the push rod 307 is automatically pushed out from the inside of the timer 304, driving the connecting plate 308 connected to the upper end surface of the push rod 307 to rise synchronously. During the rising process of the connecting plate 308, the limiting bead 315 also moves upward synchronously with the connecting plate 308. At this time, since the limiting bead 315 is slidably connected to the spiral groove 314, when the limiting bead 315 rises vertically, it will toggle the spiral groove 314, causing the position of the spiral groove 314 to change, thereby driving the rotating shaft 309 to rotate on the support plate 301, so that the rotating shaft 309 can move synchronously as soon as the timer 304 expires.

[0049] When the shaft 309 rotates, the dial plate 310 connected to the lower end can be used to dial the dial rod 306 to move synchronously with the shaft 309 as the center of the circle, and the dial rod 306 can slide in the groove 305 opened on the upper end surface of the movable plate 303. As the dial rod 306 moves, the movable plate 303 connected to the lower end surface of the dial rod 306 can push the sliding posts 302 on both sides to slide into the washing box 1 at the same time, driving the moving block 311 to slide in the slide groove 6. When the moving block 311 moves along the slide groove 6, the moving block 311 can The lifting plate 312 is able to push the lower end of the jacking plate 312 to which the upper end surface is rotatably connected to move horizontally in synchronization, so that the jacking plate 312 moves from a nearly horizontal state to a nearly vertical state. As the state of the jacking plate 312 changes, the lifting plate 313 to which the end of the jacking plate 312 away from the moving block 311 is rotatably connected will move upward in synchronization, and the lifting plate 313 will drive the storage frame 2 to rise out of the cleaning box 1 through the frame 404, so that the metal placed in the storage frame 2 and the chemical agent in the cleaning box 1 can be automatically separated after the timer 304 ends.

[0050] When the lifting plate 313 drives the frame 404 and the storage frame 2 to rise synchronously, the linkage rods 406 connected to both sides of the frame 404 will move upward synchronously. At this time, the linkage rods 406 will contact the upper corrugated plate 402. The linkage rods 406 are limited by the corrugated plates 402 on both sides and slide along the corrugations on the side walls of the corrugated plates 402. During the movement of the linkage rods 406 along the corrugations on the side walls of the corrugated plates 402, the horizontal grooves 405 provided on the side walls of the frame 404 enable the frame 404 to slide horizontally back and forth on the outer surface of the lifting plate 313, thereby driving the storage frame 2 connected between the frames 404 to shake left and right, thereby shaking off the moisture remaining on the metal surface placed inside the storage frame 2.

[0051] During the horizontal reciprocating movement of the storage frame 2, the cleaning roller 403 inside the storage frame 2, through the movable groove 408 provided on the outer surface of the connecting shaft 407, synchronously drives the outer surface of the connecting shaft 407 to move horizontally and reciprocally, so that the cleaning roller 403 can reciprocate and contact the metal surface, further removing the liquid remaining on the surface of the metal after leaving the cleaning box 1, ensuring that the metal surface has a better appearance and higher quality, so as to facilitate the subsequent electroplating tinning process on the metal surface;

[0052] When the worker places the metal in the storage frame 2, the initial position of the storage frame 2 is above the cleaning frame. The worker then places the metal in the gap between the cleaning rollers 403 in sequence, maintaining the distance between the metals. This not only allows for more precise control of the contact time and amount of the chemical agent with the metal surface, thereby ensuring a consistent cleaning effect, but also prevents the metals from contacting and colliding with each other during the cleaning process, which could cause scratches, indentations, or damage to the metal surface, thereby maintaining the integrity of the metal surface.

[0053] After the metal is placed, the staff can adjust the timing time on the timer 304 according to the type of metal. When the time adjustment is completed, the staff can press down the connecting plate 308 to drive the push rod 307 to slide into the timer 304 to realize the timing. At the same time, the connecting plate 308 drives the storage frame 2 to descend into the cleaning box 1 at the same time through the limiting bead 315, spiral groove 314, rotating shaft 309, dial plate 310, dial rod 306, groove 305, moving plate 303, sliding column 302, moving block 311, lifting plate 312, lifting plate 313, transverse groove 405 and frame 404, so that the metal in the storage frame 2 can contact with the chemical inside the cleaning box 1 while the timer 304 is counting down.

[0054] When the storage frame 2 drives the metal down to the inside of the cleaning box 1 for cleaning, as the chemical agent flows, the cleaning roller 403 inside the storage frame 2 will be impacted by the chemical agent, and the connecting shaft 407 will be driven to rotate inside the storage frame 2 through the movable groove 408, so that the cleaning roller 403 can rotate synchronously to clean the metal surface, ensuring that the metal is fully cleaned inside the cleaning box 1, reducing the cleaning time, and increasing the thoroughness of the cleaning, thereby improving the efficiency of the entire metal surface in the cleaning process.
