Description

Technical Field

[0001] This utility model relates to the field of metal wire positioning frame technology, and in particular to a scratch-resistant positioning and feeding frame structure for a tin plating machine. Background Technology

[0002] In the field of metal wire processing, tin plating is widely used for surface treatment of conductor materials such as copper wire and copper alloy wire to improve their oxidation resistance, weldability, and conductivity. The wire feeding frame, as the starting point of the entire production line, plays a crucial role in supporting, positioning, and fixing the wire.

[0003] Currently, conventional wire feeding racks mostly use simple clamping and fixing structures. The surface of the wire is easily scratched and abraded during the clamping process. In addition, traditional wire feeding racks lack effective positioning functions, and the wire is prone to displacement during the feeding process, resulting in incorrect positioning when entering the tin plating bath and affecting the integrity of the tin plating.

[0004] Therefore, it is necessary to design a scratch-resistant positioning and feeding frame structure for tin plating machines to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of easy scratching of wires and lack of effective positioning function, this utility model provides a scratch-resistant positioning wire feeding frame structure for tin plating machines.

[0006] The technical implementation scheme of this utility model is as follows: a scratch-resistant positioning and feeding frame structure for a tin plating machine, comprising a fixed plate, a positioning frame, an air bladder, a vacuum pump, an inflation pump, and an air supply pipe. There are two fixed plates, and a positioning frame is fixedly connected to the left side between the two fixed plates. An air bladder is fixedly connected to the inner side of the positioning frame. The air bladder has multiple holes for feeding wires. A vacuum pump is fixedly connected to the front left side of the fixed plate, and an inflation pump is fixedly connected to the rear left side of the fixed plate. An air supply pipe is provided between the inflation pump and the vacuum pump and the air bladder. Both air supply pipes are fixedly connected to the fixed plate and the positioning frame.

[0007] Furthermore, it also includes a transparent plate, which is fixedly connected to the top of the positioning frame.

[0008] Furthermore, it also includes clamping plates, mounting blocks, and cylinders. A clamping plate is fixedly connected between the lower middle parts of the two fixing plates, a mounting block is fixedly connected to the top of each of the two fixing plates, a cylinder is installed at the bottom of each of the two mounting blocks, and a clamping plate is also fixedly connected between the piston rods at the bottom of the two cylinders.

[0009] Furthermore, it also includes padding, with padding fixedly connected to both clamps near the center end.

[0010] Furthermore, it also includes limit rods, partitions, and guide wheels. Limit rods are fixedly connected to the upper and lower sides between the right sides of the two fixed plates. Multiple partitions are fixedly connected to each of the two limit rods. Multiple guide wheels are rotatably connected to each of the two limit rods. Each partition on the same side is located between two guide wheels, and the position of the guide wheels corresponds to the hole on the airbag.

[0011] Furthermore, it also includes rubber pads, with each guide wheel equipped with a rubber pad.

[0012] Furthermore, it also includes mounting components, with mounting components fixedly connected to both fixing plates at their ends away from the center, and each mounting component having two mounting holes.

[0013] Beneficial effects: 1. This utility model uses an airbag in conjunction with an inflation pump and a deflation pump to expand and clamp the wire during the threading and fixing stages, and contract and release it during the unloading stage, so as to achieve synchronous positioning and non-destructive fixing of multiple wires, effectively preventing tangling and displacement. Furthermore, the transparent plate allows operators to observe the inflation and deflation status of the airbag and the threading position of the wire in real time, improving the convenience, accuracy and safety of operation.

[0014] 2. This utility model achieves automatic clamping through upper and lower clamping plates and a cylinder. The inner side of the clamping plates is equipped with a soft pad, which not only firmly fixes the wire but also avoids excessive clamping force that could cause surface damage. Furthermore, the combination of guide wheels and rubber pads significantly reduces the frictional resistance when the wire passes through, preventing surface scratches, indentations, and other damage, and ensuring the smoothness of the wire surface. In addition, a partition block is set and fixed on the limit rod and located between adjacent guide wheels to ensure that each wire maintains a constant spacing, positioning and guiding the wire, and improving the neatness of wire laying and the stability of operation.

Detailed Implementation

[0020] Example: A scratch-resistant positioning and feeding frame structure for a tin plating machine, such as... Figure 1 , Figure 2 and Figure 3 As shown, it includes a fixed plate 1, a positioning frame 2, an airbag 3, a vacuum pump 5, an inflation pump 6, and an air supply pipe 7. There are two fixed plates 1. The positioning frame 2 is welded between the two fixed plates 1 on the left side. The airbag 3 is fixedly connected to the inside of the positioning frame 2. The airbag 3 has multiple holes for laying lines. The vacuum pump 5 is fixedly connected to the front left side of the fixed plate 1 by bolts. The inflation pump 6 is fixedly connected to the rear left side of the fixed plate 1 by bolts. An air supply pipe 7 is provided between the inflation pump 6 and the vacuum pump 5 and the airbag 3. Both air supply pipes 7 are fixedly connected to the fixed plate 1 and the positioning frame 2.

[0021] like Figure 1 and Figure 3 As shown, it also includes a transparent plate 4, and the top of the positioning frame 2 is fixedly connected to the transparent plate 4.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes a clamping plate 8, a mounting block 9, and a cylinder 10. The clamping plate 8 is fixedly connected between the lower parts of the two fixing plates 1 by bolts. The mounting block 9 is fixedly connected to the top of the two fixing plates 1 by bolts. The cylinder 10 is installed at the bottom of the two mounting blocks 9. The clamping plate 8 is also fixedly connected between the piston rods at the bottom of the two cylinders 10.

[0023] like Figure 3 As shown, it also includes a soft pad 11, and both clamps 8 are provided with soft pads 11 near the center end.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes a limit rod 12, a partition block 13 and a guide wheel 14. Limit rods 12 are fixedly connected to the upper and lower sides of the right side of the two fixed plates 1. Multiple partition blocks 13 are fixedly connected to each of the two limit rods 12. Multiple guide wheels 14 are rotatably connected to each of the two limit rods 12. Each partition block 13 on the same side is located between two guide wheels 14, and the position of the guide wheel 14 corresponds to the hole on the airbag 3.

[0025] like Figure 4 As shown, it also includes a rubber pad 15, and each guide wheel 14 is provided with a rubber pad 15.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes mounting parts 16. The two fixing plates 1 are each welded with mounting parts 16 at the ends away from the center. Each mounting part 16 has two mounting holes.

[0027] When this device is used for wire feeding operations in a tin plating machine, first, the structure is securely installed in the corresponding position on the tin plating machine through the mounting holes on the two mounting pieces 16 to ensure accurate overall positioning. Then, the end of the wire to be tinned is passed sequentially between the upper and lower guide wheels 14 on the right side, then between the two clamping plates 8, and finally introduced into the corresponding hole on the airbag 3 inside the positioning frame 2. The outer ring of the guide wheel 14 is equipped with a rubber pad 15, which is soft and smooth, forming a flexible contact with the wire, effectively reducing frictional resistance and preventing scratches. The spacer 13 positions the guide wheel 14 and ensures that each wire maintains a fixed spacing, making it difficult for it to shift. The limit rod 12 provides structural support to ensure the stable arrangement of the guide wheels 14.

[0028] After placement, the air pump 6 is started, and gas is injected into the airbag 3 through the air supply pipe 7, causing the airbag 3 to expand. The expanded airbag 3 tightly adheres the inner walls of its multiple holes to the surface of the wire, achieving synchronous positioning and fixation of multiple wires, preventing them from tangling or shifting laterally during subsequent wire laying. Then, the cylinder 10 is started, causing its piston rod to extend downward, driving the upper clamping plate 8 to move down and cooperate with the lower clamping plate 8 to clamp the wire. The soft pad 11 on the inner side of the clamping plate 8 is made of rubber or silicone, which undergoes elastic deformation during clamping, which can not only firmly fix the wire but also avoid damage to the wire surface due to excessive pressure. Then, the workers use a tinning machine to tin the ends of the wire.

[0029] After tin plating is completed, the air pump 5 is started to extract the gas from the airbag 3 through the air supply pipe 7, causing the airbag 3 to contract and the inner wall of the hole to separate from the surface of the wire. Then, the cylinder 10 is started to drive the upper clamping plate 8 to reset and release the wire. The tin-plated wire can then be taken out. The transparent plate 4 at the top of the positioning frame 2 allows the operator to observe the inflation and deflation status of the airbag 3 and the wire threading in real time, improving the convenience and safety of operation.
