Description

Technical Field

[0001] This utility model relates to the field of tin plating equipment technology, specifically a tin plating equipment for core support processing. Background Technology

[0002] Core supports are widely used in industrial production. To improve their corrosion resistance, solderability, and other properties, their surfaces are usually tin-plated.

[0003] An existing patent (authorization announcement number: CN222666011U) discloses an acid tin plating equipment for copper busbars used in electrical components. By setting up structures such as an acid pickling tank, a suspension assembly, and a spraying assembly, the equipment performs immersion and shaking acid pickling in the lower half of the acid pickling tank and rinsing in the upper half of the acid pickling tank to remove residual impurities from the surface of the copper busbars and improve processing efficiency.

[0004] However, the above technical solutions still have certain drawbacks. The above device achieves the connection and disassembly of the cover plate and the support frame by rotating the locking block and the connecting plate. In actual operation, this method is relatively cumbersome and requires rotating the locking block and the cover plate multiple times. Especially in mass production, it will increase the workload of operators and reduce production efficiency. At the same time, the connection between the locking block and the connecting plate may become loose during the tin plating process due to factors such as the shaking of the molten tin and temperature changes. This may cause the cover plate to separate from the support frame, causing the core support to fall into the molten tin, resulting in production accidents and material waste. Therefore, a tin plating equipment for core support processing is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a tin-plating device for core support processing to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A tin plating device for core support processing includes a hot-dip tin plating tank body. A tin plating chamber is formed within the hot-dip tin plating tank body. An insulation plate is provided on the top of the tin plating chamber. A lifting assembly is provided within the tin plating chamber. The lifting assembly includes a movable chamber formed within the side wall of the tin plating chamber. A lead screw is longitudinally arranged within the movable chamber. A T-shaped block is threaded onto the outer wall of the lead screw. One end of the T-shaped block extends through the tin plating chamber, and a tin plating box body is mounted on one end of the T-shaped block. The tin plating box body includes a mounting frame. A support frame is fixedly connected to the bottom of the mounting frame. A cover plate is provided above the mounting frame. The cover plate is connected to the mounting frame via a locking assembly. The locking assembly includes slots at both ends of the upper surface of the mounting frame. Movable chambers communicating with the slots are formed at both ends of the mounting frame. Trapezoidal blocks are slidably connected within the movable chambers. A spring is fixedly connected between the end of the trapezoidal block away from the slot and the movable chamber.

[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0009] In one alternative: each set of trapezoidal blocks is fixedly connected to a connecting rod at the end away from the slot, and the other end of each set of connecting rods extends through to the outside of the mounting bracket. Two sets of connecting rods on the same side are fixedly connected to the same pull rod at one end, and each set of springs is movably sleeved on the outer wall of the corresponding connecting rod.

[0010] In one alternative: both ends of the bottom of the cover plate are fixedly connected with inserts that match the slots, and both sides of the two sets of inserts are provided with slots that match the trapezoidal card blocks.

[0011] In one alternative: a second motor for driving the tin plating box body to rotate is fixedly installed inside one end of the T-shaped block, and a clearance groove matching the T-shaped block is opened on the side wall of the tin plating chamber.

[0012] In one alternative: a first motor for driving the lead screw to rotate is fixedly installed on the top of the hot-dip galvanizing tank body.

[0013] In one alternative: handles are fixedly installed at both ends of the top of the cover plate.

[0014] In one alternative: an observation window is provided on the front side of the hot-dip galvanizing box body, and casters are fixedly installed at the four corners of the bottom of the hot-dip galvanizing box body.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model adopts an alignment and insertion design of the plug and slot, combined with a spring-driven trapezoidal locking mechanism, which eliminates the need for complicated rotation and adjustment operations, and enables quick installation of the cover plate. When disassembling, only the pull rod needs to be pulled to unlock quickly, which greatly simplifies the installation and removal process of the cover plate, significantly improves the fixing efficiency, and saves manual operation time and effort.

[0017] 2. This utility model utilizes the tight fit between the trapezoidal card block's arc-shaped inclined surface and the insertion block's slot, combined with the continuous clamping force generated by the spring's elastic potential energy, to ensure a firm connection between the cover plate and the mounting bracket. This effectively resists the influence of external forces such as vibration and shaking generated during the tin plating process, ensuring the stability of the overall structure of the tin plating box, thereby providing a stable tin plating environment for the core support workpiece and improving tin plating quality and yield.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] In one embodiment, such as Figures 1-5As shown, a tin plating device for core support processing includes a hot-dip tin plating tank body 100, a tin plating chamber 110 inside the hot-dip tin plating tank body 100, a heat insulation plate 120 on the top of the tin plating chamber 110, and a lifting assembly 200 inside the tin plating chamber 110. The lifting assembly 200 includes a movable chamber 210 opened in the side wall of the tin plating chamber 110, and a lead screw 220 is longitudinally arranged inside the movable chamber 210. A T-shaped block 230 is threadedly connected to the outer wall of the lead screw 220. One end of the T-shaped block 230 extends through the tin plating chamber 110, and a tin plating box body 240 is installed at one end of the T-shaped block 230. The tin plating box body 240 includes a mounting frame 241, a support frame 242 fixedly connected to the bottom end of the mounting frame 241, and a cover plate 243 above the mounting frame 241. The cover plate 243 is connected to the mounting frame 241 through a locking assembly 300. The locking assembly 300 includes... The mounting bracket 241 includes slots 310 at both ends of the upper surface. The mounting bracket 241 has movable chambers at both ends that communicate with the slots 310. Trapezoidal blocks 320 are slidably connected in the movable chambers. A spring 340 is fixedly connected between the end of the trapezoidal block 320 away from the slot 310 and the movable chamber. A connecting rod 330 is fixedly connected to the end of each trapezoidal block 320 away from the slot 310. The other end of each connecting rod 330 extends through to the outside of the mounting bracket 241. The same pull rod 350 is fixedly connected to one end of two sets of connecting rods 330 on the same side. Each spring 340 is movably sleeved on the outer wall of the corresponding connecting rod 330. The bottom ends of the cover plate 243 are fixedly connected to the inserts 360 that match the slots 310. The two sets of inserts 360 have slots 370 on both sides that match the trapezoidal blocks 320.

[0029] In this embodiment, when the core support workpiece needs to be tin-plated, the core support to be tin-plated is placed in the support frame 242, and then the cover plate 243 is fixed to the top of the mounting bracket 241 by the engaging assembly 300. Specifically, the operator aligns the insert 360 at the bottom of the cover plate 243 with the slot 310 on the mounting bracket 241, and then pushes it into it. During this process, the two sets of trapezoidal locking blocks 320, which were initially in a fitted state, are squeezed apart from the middle to both sides, and the inclination of the trapezoidal locking blocks 320... The inclined surface is designed as an arc-shaped inclined surface. When the two sets of trapezoidal locking blocks 320 slide into the corresponding movable chambers, the spring 340 is compressed and possesses elastic potential energy. When the insert block 360 is fully inserted into the bottom of the slot 310, the two sets of trapezoidal locking blocks 320 move and insert into the slots 370 on both sides of the insert block 360 under the elastic potential energy of the spring 340, thus completing the fixation of the insert block 360 and the cover plate 243. When it is necessary to remove the cover plate 243, simply pull the pull rods 350 on both sides of the mounting bracket 241 to move the... Once the two sets of connecting rods 330 and trapezoidal locking blocks 320 are disengaged from the slots 370 on both sides of the insert block 360, the fixing can be released. Then, the operator can easily remove the cover plate 243. By setting the locking component 300, the cover plate 243 can be quickly connected and removed. The operation is simple and quick, which greatly improves the fixing efficiency of the cover plate 243. At the same time, the cooperation between the insert block 360 and the trapezoidal locking block 320 can make the cover plate 243 and the mounting bracket 241 firmly connected and not easy to loosen, effectively ensuring the overall firmness of the tin plating box body 240. Then, the lifting component 200 lowers the tin plating box body 240 into the molten tin inside the tin plating chamber 110. It is worth noting that the center of the support frame 242 and the cover plate 243 are both set with a hollow structure of metal mesh. The molten tin can enter the support frame 242 and adhere to the surface of the core support workpiece. By designing the tin plating box body 240, the surface of the core support workpiece is effectively protected, reducing the possibility of surface damage to the workpiece and ensuring the subsequent processing and use effect of the workpiece.

[0030] In one embodiment, such as Figure 2 and Figure 4 As shown, a second motor 260 for driving the tin plating box body 240 to rotate is fixedly installed inside one end of the T-shaped block 230. The side wall of the tin plating chamber 110 is provided with a relief groove that matches the T-shaped block 230. By setting the second motor 260, the tin plating box body 240 can be driven to rotate as a whole in the tin plating chamber 110, so that the tin plating on the surface of the workpiece is more uniform and thorough. By opening the relief groove, the T-shaped block 230 is provided with a moving space for moving up and down.

[0031] In one embodiment, such as Figure 2As shown, a first motor 250 for driving the lead screw 220 to rotate is fixedly installed on the top of the hot plating box body 100; by setting the first motor 250 to drive the lead screw 220 to rotate, the T-shaped block 230 and the tin plating box body 240 are moved up and down.

[0032] In one embodiment, such as Figure 5 As shown, handles 244 are fixedly installed at both ends of the top of the cover plate 243; by setting handles 244, it is convenient for staff to pick up the cover plate 243.

[0033] In one embodiment, such as Figure 1 As shown, an observation window 130 is provided on the front side of the hot-dip galvanizing tank body 100, and casters 140 are fixedly installed at the four corners of the bottom of the hot-dip galvanizing tank body 100. By providing a transparent observation window 130, it is convenient for staff to observe the amount of molten tin in the tin plating chamber 110 and the tin plating status of the workpiece. By designing casters 140, the overall flexibility of the device is improved.

[0034] The above embodiment discloses a tin-plating device for core support processing. In this device, the operator aligns the insert 360 at the bottom of the cover plate 243 with the slot 310 on the mounting bracket 241 and then pushes it into the slot. During this process, two sets of trapezoidal locking blocks 320, initially in a fitted state, are pushed apart from the middle. The inclined surfaces of the trapezoidal locking blocks 320 are set as arc-shaped inclined surfaces. When the two sets of trapezoidal locking blocks 320 slide into the corresponding movable chambers, the spring 340 is compressed and possesses elastic potential energy. When the insert 360 is fully inserted to the bottom of the slot 310, the two sets of trapezoidal locking blocks 320 move under the elastic potential energy of the spring 340 and insert into the slots 370 on both sides of the insert 360, completing the plating of the insert 360 and the cover plate. Fixing plate 243: When it is necessary to remove the cover plate 243, simply pull the pull rods 350 on both sides of the mounting bracket 241, which will cause the two sets of connecting rods 330 and trapezoidal locking blocks 320 fixed thereto to disengage from the slots 370 on both sides of the insert block 360, thereby releasing its fixation. Then, the staff can easily remove the cover plate 243. By setting the locking component 300, the quick connection and removal of the cover plate 243 can be achieved. The operation is simple and quick, which greatly improves the fixing efficiency of the cover plate 243. At the same time, the cooperation between the insert block 360 and the trapezoidal locking block 320 can make the cover plate 243 and the mounting bracket 241 firmly connected and not easy to loosen, effectively ensuring the overall firmness of the tin-plating box body 240, and also improving the stability of the tin plating of the core support workpiece.

[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
