Description

Technical Field

[0001] This invention relates to the field of traction technology, and more particularly to a wire traction mechanism. Background Technology

[0002] Brain cotton pads are made primarily of medical-grade degreased cotton or spunlace nonwoven fabric, with X-ray detectable barium or polyester threads as auxiliary materials. During production, the threads are conveyed to one side via a material traction mechanism. As the threads pass through a welding machine, workers regularly place them on the cotton pad, and then the welding machine welds the threads onto the cotton pad.

[0003] In existing technologies, traction mechanisms can transfer wire from one spool to another. For example, in enameled wire processing, the processing equipment processes the wire between two spools, and the finished product is wound onto one of the spools. However, the processing of cotton pads requires placing the front part of the wire on the cotton pad for welding. During welding, the wire breaks at the welding machine, so the commonly used traction mechanisms are not suitable for this field. Cotton pads can only be produced manually by ultrasonically welding barium wire or chemical fiber onto the cotton pad, with welding done in multiple steps, and finally separating the pieces. The entire production process involves multiple workstations and material transfers, resulting in significant pollution, waste, low efficiency, and wasted labor. Therefore, the method of placing barium wire or chemical fiber needs to be improved. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a wire pulling mechanism that solves the problems of low efficiency and excessive waste when using manual pulling.

[0005] According to an embodiment of the present invention, a wire traction mechanism includes a wire guide rod, a linear drive assembly, a first cylinder, a first wire clamping assembly, and a second wire clamping assembly. The wire guide rod has a columnar structure and a plurality of annular grooves arranged side by side on the wire guide rod, and the wire guide rod is horizontally arranged. The linear drive assembly is horizontally arranged and perpendicular to the wire guide rod. The first wire clamping assembly is arranged on the side of the linear drive assembly near the wire guide rod and can fix the wire passing through the wire guide rod. The first cylinder is vertically arranged, and the cylinder barrel of the first cylinder is fixedly connected to the output section of the linear drive assembly. The movable end of the first cylinder is fixedly connected to the second wire clamping assembly.

[0006] The technical principle of this invention is as follows: the wire guide rod makes the wires evenly spaced; the second wire clamping assembly clamps the wires and moves along the linear drive assembly to the other side of the welding machine; at the same time, the first wire clamping assembly fixes the wires of the welding machine; the welding machine starts welding; then the second wire clamping assembly moves between the first wire clamping assembly and the wire guide rod to clamp the wires; then it moves to the other side of the welding machine, and so on.

[0007] Preferably, the first wire clamping assembly includes a second cylinder, a first clamping cylinder, a first clamping rod, and a second clamping rod. The second cylinder is fixedly disposed on one side of the wire guide rod. The fixed end of the first clamping cylinder and the movable end of the second cylinder are fixedly connected. The first clamping rod and the second clamping rod are parallel to each other and arranged vertically. The corresponding ends of the first clamping rod and the second clamping rod are respectively fixedly connected to the two movable ends of the first clamping cylinder.

[0008] Preferably, the second clamping assembly includes a fixing base, a second clamping cylinder, a first clamping part, and a second clamping part. The fixing base is a horizontally arranged elongated structure, parallel to the wire guide rod, and one end of the fixing base is fixedly connected to the movable end of the first cylinder. The second clamping cylinder is fixedly connected to the fixing base. The first clamping part and the second clamping part are horizontally arranged strip structures that are adjacent to each other. Below the first clamping part and the second clamping part, there are first clamping heads and second clamping heads arranged in a staggered manner. The first clamping heads and the second clamping heads are arranged on the same straight line, and the interval between adjacent first clamping heads and second clamping heads corresponds to the position and number of the wire. The tops of the first clamping part and the second clamping part are fixedly connected to the two movable ends below the second clamping cylinder.

[0009] Preferably, the assembly also includes a collection trough, which is located at one end of the linear drive assembly, and the top opening of the collection trough is located below the movement trajectory of the second clamping wire assembly.

[0010] Preferably, the system also includes a fixedly installed air nozzle, which is located above the collection groove and corresponds to the opening of the collection groove.

[0011] Preferably, the fixing seat is an L-shaped structure composed of a horizontal part and a vertical part, and the vertical part is attached to and fixedly connected to the movable end of the first cylinder.

Detailed Implementation

[0023] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Implementation method one: such as Figure 1 , 2As shown in Figures 3 and 4, this embodiment of the invention proposes a wire traction mechanism, which is configured in conjunction with a welding machine 23. The welding machine 23 includes an upper mold 1 and a lower mold 2. The upper mold 1 and the lower mold 2 are opened and closed by a mold closing machine, which is fixedly placed on a worktable 9. This mechanism includes a wire guide rod 10, a linear drive assembly 3, a first cylinder 4, a first wire clamping assembly 21, and a second wire clamping assembly 22. The wire guide rod 10, the linear drive assembly 3, the first cylinder 4, the first wire clamping assembly 21, and the second wire clamping assembly 22 are all fixed on the worktable 9. The wire guide rod 10 has a cylindrical structure, and several annular grooves are arranged side by side on the wire guide rod 10. In this example, the wire guide rod 10 is composed of a guide rod and several circular stainless steel baffles, and the distance between the baffles is adjusted according to the product specifications. The wire guide rod 10 is horizontally positioned on one side of the lower die 1 of the welding machine 23. First support members are provided at both ends of the wire guide rod 10 and are rotatably connected to the first support members. The bottom of the first support members is fixedly connected to the worktable 9. The wire guide rod 10 ensures that adjacent wires always maintain a corresponding interval. The linear drive assembly 3 is horizontally positioned on one side of the wire guide rod 10. The two ends of the linear drive assembly 3 are fixedly connected to the worktable 9 via second support members 15, so that the linear drive assembly 3 is located above the worktable 9 and at a certain distance from it. The linear drive assembly 3 is horizontally fixedly positioned on one side of the welding machine 23 and perpendicular to the axis of the wire guide rod 10. One end of the linear drive assembly 3 extends from one side of the welding machine 23 where the wire guide rod 10 is located to the other side of the welding machine 23. The first wire clamping assembly 21 is located on the side of the linear drive assembly 3 near the wire guide rod 10 and can fix the wire passing through the wire guide rod 10. The first wire clamping assembly 21 is positioned between the wire guide rod 10 and the welding machine 23. The first cylinder 4 is a vertically moving slide cylinder, with its cylinder barrel slidably connected to the output end of the linear drive assembly 3. The movable end of the first cylinder 4 is fixedly connected to the second wire clamping assembly 22. The first cylinder 4 drives the second wire clamping assembly 22 to move up and down. After fixing the wire at one end of the linear drive assembly 3, the second wire clamping assembly 22 moves to the other end and then releases the wire.

[0025] Preferably, the linear drive component 3 is a slide cylinder.

[0026] After the second wire clamping assembly 22 fixes the wire between the wire guide rod 10 and the first wire clamping assembly 21, it pulls the wire through the lower mold 1 and moves it along the linear drive assembly 3 to the other side of the lower mold 1. When the upper mold 2 and the lower mold 1 close, the welding work between the wire and the cotton sheet is completed. When the upper mold 2 and the lower mold 1 separate, the second wire clamping assembly 22 moves between the first wire clamping assembly 21 and the wire guide rod 10 to clamp the wire, and this process is repeated. When the second wire clamping assembly 22 pulls the wire over the lower mold 1, the first cylinder 4 extends and retracts, causing the second wire clamping assembly 22 to descend, thereby making the wire and the cotton sheet on the lower mold 1 fit together. The wire is released before welding to prevent the wire from shifting on the cotton sheet.

[0027] like Figure 1 , 2 As shown in Figure 6, preferably, the first wire clamping assembly 21 includes a second cylinder 11, a first clamping cylinder 12, a first clamping rod 13, and a second clamping rod 14. The second cylinder 11 is fixedly disposed on one side of the wire guide rod 10, and the movable end of the second cylinder 11 passes through the area traversed by the wire. The moving direction of the movable end of the second cylinder 11 is perpendicular to the moving direction of the wire. The second cylinder 11 is fixedly connected to the worktable 9. The fixed end of the first clamping cylinder 12 is fixedly connected to the movable end of the second cylinder 11. The first clamping rod 13 and the second clamping rod 14 are parallel to each other and arranged vertically. The corresponding ends of the first clamping rod 13 and the second clamping rod 14 are respectively fixedly connected to the two movable ends of the first clamping cylinder 12. The first clamping cylinder 12 is a double-headed clamping cylinder. When the movable end of the second cylinder 11 extends, it drives the first clamping cylinder 12 to move. The first clamping rod 13 and the second clamping rod 14 on the first clamping cylinder 12 can move to the upper and lower positions of the wire. Then, the first clamping cylinder 12 drives the first clamping rod 13 and the second clamping rod 14 to move closer to each other to clamp the wire, so as to avoid the need to find the wire end again after the wire retracts. When the second cylinder 11 retracts, it drives the first clamping rod 13 and the second clamping rod 14 on the first clamping cylinder 12 away from the upper and lower areas of the wire to avoid affecting the movement of the wire.

[0028] like Figure 1 , 4As shown in Figure 5, preferably, the second wire clamping assembly 22 includes a fixing base 5, a second clamping cylinder 6, a first clamping part 7, and a second clamping part 8. The fixing base 5 is a horizontally arranged elongated structure, parallel to the wire guide rod 10, and one end of the fixing base 5 is fixedly connected to the movable end of the first cylinder 4. The second clamping cylinder 6 is fixedly arranged below the fixing base 5. The first clamping part 7 and the second clamping part 8 are horizontally arranged strip structures and are adjacent to each other, parallel to the wire guide rod 10. Below the first clamping part 7 and the second clamping part 8, a first clamping head 18 and a second clamping head 24 are respectively arranged in a staggered manner. The first clamping head 18 and the second clamping head 24 are arranged on the same straight line, and the interval area between adjacent first clamping heads 18 and second clamping heads 24 corresponds to the position of the wire and the number of clamping heads corresponds to the position of the wire. The tops of the first clamping part 7 and the second clamping part 8 are fixedly connected to the two movable ends below the second clamping cylinder 6, respectively. When the first clamping part 7 and the second clamping part 8 move relative to each other, they can clamp the wire sequentially. When the two movable ends of the second clamping cylinder 6 separate, the first clamping part 7 and the second clamping part 8 are driven to move relatively parallel, increasing the gap between the first clamping head 18 and the second clamping head 24 at the bottom of the first clamping part 7 and the second clamping part 8, thus preventing the wire from being clamped. Conversely, when the two movable ends of the second clamping cylinder 6 close, the first clamping part 7 and the second clamping part 8 are driven to move relatively parallel, decreasing the gap between the first clamping head 18 and the second clamping head 24 at the bottom of the first clamping part 7 and the second clamping part 8, thus clamping the wire.

[0029] like Figure 1 , 2 As shown, preferably, a collection trough 16 is also included. The waste collection trough 16 is located at one end of the linear drive assembly 3, and the top opening of the collection trough 16 is located below the moving trajectory of the second wire clamping assembly 22. After the wire is soldered, the end of the wire away from the first clamping assembly 21 will fall into the collection trough 16.

[0030] Preferably, a fixed air nozzle is also included, which is located above the collection groove 16 and corresponds to the opening of the collection groove 16. After welding, the wire located on the side of the welding machine 23 away from the wire guide rod 10 is the material that needs to be scrapped. In order to prevent the wire from sticking to the first clamping head 18 and the second clamping head 24, the air nozzle is used to blow on the clamping head 18 to ensure the separation of the wire end and the clamping head 18.

[0031] like Figure 1 As shown, preferably, the fixing base 5 is an L-shaped structure composed of a horizontal part and a vertical part, and the vertical part is fitted and fixedly connected to the movable part of the first cylinder 4. In this example, the L-shaped structure is provided with reinforcing ribs to ensure structural strength.

[0032] Preferably, a cable chain 19 is fixedly disposed above the linear drive assembly 3. The cable chain 19 contains power lines or signal lines for the detection components.

[0033] like Figure 2 As shown, preferably, a secondary guide rail 20 is also included. The secondary guide rail 20 is horizontally fixed below the movement trajectory of the second clamping cylinder 6, and the second clamping cylinder 6 and the secondary guide rail 20 are slidably connected. This prevents the second clamping cylinder 6 from falling when it moves away from the first cylinder 4, thus preventing the first clamping part 7 and the second clamping part 8 from accurately moving to the upper and lower positions of the wire and performing the clamping operation.

[0034] Implementation Method Two:

[0035] The linear drive assembly 3 includes a main guide rail with two parallel T-slots. The bottom of the cylinder of the first cylinder 4 is fixedly provided with a corresponding T-shaped sliding part, which slides in conjunction with the T-slots. A second servo motor is fixedly connected to the end of the main guide rail. A cavity is provided inside the main guide rail and a screw is installed therein. The output shaft of the second servo motor and several ends of the screw are fixedly connected. The sliding part fixed on the first cylinder 4 is provided with a threaded hole that is threadedly connected to the screw. When the screw rotates, it drives the first cylinder 4 to move along the main guide rail.

[0036] The rest of the structure is the same as in Implementation Method 1.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
