Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of copper strip tin plating equipment, and particularly relates to a tin plating equipment for improving the weldability of copper strips. Background Art

[0002] A copper strip is a metal component, mainly used for producing electrical components, lamp caps, battery caps, buttons, seals, connectors, and mainly used as conductive, heat-conductive, and corrosion-resistant materials. Copper strip tin plating is a common surface treatment method. Copper strip tin plating can increase the weldability of copper strips, reduce the welding difficulty, and reduce the smoke and harmful gases generated during the welding process.

[0003] In the existing process of tin plating copper strips, the copper strips are directly placed in the tin solution. After the copper strips are tin plated, it is inconvenient to take the copper strips. In the prior art, the copper strips are also placed on a partition plate and then placed in the tin solution for tin plating. However, the side of the copper strip close to the partition plate is blocked by the partition plate, resulting in inconsistent tin plating thickness on each side of the copper strip during tin plating. Summary of the Utility Model

[0004] Therefore, the embodiment of the utility model provides a tin plating equipment for improving the weldability of copper strips to solve the problem of inconsistent tin plating thickness on each side of the copper strip placed on the partition plate during tin plating in the prior art.

[0005] In order to achieve the above object, the embodiment of the utility model provides the following technical solutions:

[0006] A tin plating equipment for improving the weldability of copper strips includes a tin plating tank.

[0007] A limiting box is installed inside the tin plating tank, and two loading devices for holding copper strips are installed at the lower end inside the limiting box.

[0008] The limiting box includes a box body, and a sprocket two for controlling the rotation of the loading device is installed at the lower end of the box body.

[0009] The loading device includes a loading barrel, and the loading barrel includes a rotating barrel, and a plurality of loading grooves for placing copper strips are formed on the outer wall of the rotating barrel.

[0010] The loading device includes a limiting component for limiting the copper strips.

[0011] Further, a sprocket one is installed at the upper end of the box body, and a motor for controlling the rotation of the sprocket one is installed at one end of the sprocket one.

[0012] Further, a chain for controlling the rotation of the sprocket two is sleeved outside the sprocket one, and through grooves are formed on the side wall and the bottom of the box body.

[0013] Furthermore, a rotating shaft is installed in the middle of the rotating barrel, and the rotating shaft is connected to the middle of the sprocket wheel 2, and through holes are opened on both sides of the groove cavity of the bearing groove.

[0014] Furthermore, a gear is installed at one end of the rotating barrel, and a plurality of limiting holes are opened in the middle of the gear.

[0015] Furthermore, a fixing ring is installed at the other end of the rotating barrel, a magnetic block a is installed inside the fixing ring, and an annular groove is opened on one side of the fixing ring.

[0016] Furthermore, the limiting assembly includes a first retaining ring for limiting the copper strip, a plurality of connecting ropes for limiting the first retaining ring are installed in the middle of the first retaining ring, and one end of the connecting rope is in the cavity of the limiting hole, and a plurality of limiting blocks are installed in the middle of the connecting rope.

[0017] Furthermore, the other end of the connecting rope is connected to a limiting ring, and a magnetic block b that attracts the magnetic block a is installed inside the limiting ring.

[0018] The utility model embodiment has the following advantages:

[0019] The copper belt is placed in the groove cavity of the bearing groove, and the limit ring is moved from the end close to the gear toward the fixed ring. Under the limit of the limit block, the connecting rope synchronously drives multiple first retaining rings to move to the middle of the rotating barrel, so that the first retaining ring can limit the copper belt. The magnetic block a and the magnetic block b attract each other, so that the first retaining ring is firmly fixed in the middle of the rotating barrel to prevent the copper belt from escaping from the groove cavity of the bearing groove when the rotating barrel rotates. The motor drives the sprocket one to rotate slowly, and the chain drives the sprocket two to rotate slowly synchronously, so that the rotating shaft drives the rotating barrel to rotate, which is convenient for the copper belt to be fully tinned, so that the tin plating thickness of each side of the copper belt remains consistent.

[0036] Please refer to Figures 1-5 , the present utility model provides a tin plating device for improving the weldability of copper strips, including a tin plating tank 100.

[0037] A limit box 001 is installed inside the tin plating tank 100. The limit box 001 includes a box body 200. A first sprocket 210 is movably installed at the upper end of the box body 200. One end of the first sprocket 210 is installed with a motor 211 for controlling the rotation of the first sprocket 210. A second sprocket 220 for controlling the rotation of the carrying device 002 is movably installed at the lower end of the box body 200.

[0038] A chain 230 for controlling the rotation of the second sprocket 220 is sleeved outside the first sprocket 210. Through grooves 240 are opened on the side wall and bottom of the box body 200. The motor 211 drives the first sprocket 210 to rotate, so that the chain 230 synchronously drives the second sprocket 220 to rotate. The second sprocket 220 drives the carrying device 002 to rotate, and the tin liquid flows through the through grooves 240 to the copper strip in the cavity of the carrying groove 320, facilitating tin plating of the copper strip.

[0039] Two carrying devices 002 for holding copper strips are installed at the lower end inside the limit box 001. The carrying device 002 includes a carrying barrel 300. The carrying barrel 300 includes a rotating barrel 310. A rotating shaft 311 is fixedly installed in the middle of the rotating barrel 310, and the rotating shaft 311 is fixedly connected to the middle of the second sprocket 220. When the second sprocket 220 rotates, the rotating barrel 310 is synchronously driven to rotate, facilitating tin plating of the copper plate. A plurality of carrying grooves 320 for placing copper strips are opened on the outer wall of the rotating barrel 310. The cavity length of the carrying groove 320 is longer than the length of the copper strip, facilitating tin plating at both ends of the copper strip. Through holes 321 are opened on both sides of the cavity of the carrying groove 320. The through holes 321 are used to communicate two adjacent carrying grooves 320, facilitating the flow of tin liquid.

[0040] A gear 330 is fixedly installed at one end of the rotating barrel 310. A plurality of limit holes 331 are opened in the middle of the gear 330, and the connecting rope 430 is located in the cavity of the limit hole 331. Through the setting of the gear 330, it is convenient for the rotating barrel 310 to drive other rotating barrels 310 to rotate in cooperation with the gear 330. A fixing ring 340 is fixedly installed at the other end of the rotating barrel 310. A magnetic block a341 is fixedly installed inside the fixing ring 340. An annular groove 342 is opened on one side of the fixing ring 340. The limit block 431 is placed in the cavity of the annular groove 342, facilitating the attraction between the magnetic block b421 and the magnetic block a341, so that the first retaining ring 410 limits the copper strip to prevent the copper strip from falling.

[0041] The carrying device 002 includes a limiting component 400 for limiting the copper belt, and the limiting component 400 includes a first retaining ring 410 for limiting the copper belt. Multiple first retaining rings 410 can be provided, and multiple connecting ropes 430 for limiting the first retaining ring 410 are installed in the middle of the first retaining ring 410, and one end of the connecting rope 430 is in the cavity of the limiting hole 331, and multiple limiting blocks 431 are fixedly installed in the middle of the connecting rope 430. Limiting blocks 431 are provided at both ends of the first retaining ring 410 and both ends of the limiting ring 420 to prevent the first retaining ring 410 from sliding when the rotating barrel 310 drives the limiting component 400 to rotate.

[0042] The other end of the connecting rope 430 is connected to the limiting ring 420, and a magnetic block b421 that attracts the magnetic block a341 is fixedly installed inside the limiting ring 420.

[0043] The copper belt is placed in the groove cavity of the bearing groove 320, and the limiting ring 420 is moved from the end close to the gear 330 to the direction of the fixed ring 340. Under the limitation of the limiting block 431, the connecting rope 430 synchronously drives multiple first retaining rings 410 to move to the middle of the rotating barrel 310, so that the first retaining ring 410 can limit the copper belt. The magnetic block a341 and the magnetic block b421 attract each other, so that the first retaining ring 410 is firmly fixed in the middle of the rotating barrel 310 to prevent the copper belt from escaping from the groove cavity of the bearing groove 320 when the rotating barrel 310 rotates. The motor 211 drives the sprocket 1 210 to rotate slowly, and the chain 230 drives the sprocket 2 220 to rotate synchronously and slowly, so that the rotating shaft 311 drives the rotating barrel 310 to rotate, so that the copper belt can be fully tinned.
