Description

Technical Field

[0001] The utility model relates to the technical field of flexible material welding, in particular to a flexible material welding fixture. Background Art

[0002] For a long time, copper foil welding has mainly been done by brazing, soldering, hot pressing, gas welding, etc. In recent years, with the development of welding technology, high-energy heat sources such as electron beams and lasers have been used for welding, achieving good results.

[0003] in,

[0004] The hot press welding method is to use high temperature and high pressure to make the copper foil tightly bond the two materials together. This method is suitable for connecting thin plate materials, but it requires high temperature and pressure and is prone to deformation.

[0005] The tin soldering method is to apply solder to the surface of copper foil and other metal materials, and then heat it with a soldering iron or flame to melt the solder and combine the two materials. This method is suitable for connecting thin plate materials, but it requires higher temperatures and soldering skills.

[0006] Brazing is to coat the surface of copper foil and other metal materials with solder, and then heat them with flame or electric arc to melt the solder and combine the two materials. This method is suitable for connecting thicker materials, but requires higher temperatures and welding skills.

[0007] Laser welding is a method of using a laser beam to heat and melt copper foil and other metal materials, so that the two materials are tightly combined. This method is suitable for connecting high-precision and high-strength materials, but it requires higher equipment and technical requirements.

[0008] Copper foil generally has two processes: polymer diffusion welding and argon arc welding. The copper foil produced by polymer diffusion welding has no weld scars and a smooth appearance, while the copper foil produced by argon arc welding has weld scars.

[0009] Ultrasonic welding of copper foil is a process where an ultrasonic generator and transducer convert high-frequency electrical energy into mechanical vibration energy, which is then applied to the surface of the workpiece through a metal welding mold to generate high-frequency friction. Frictional heating generates the melting temperature of the metal molecular layer. Then, the mold and spot welding mode are used to melt the metal workpieces together under pressure and cool them quickly to achieve a perfect welding effect.

[0010] Argon arc welding is very flexible, but due to the large welding heat input, large heat-affected zone, and slow cooling of the weld joint, it is easy to cause solidification cracks in the weld and liquefaction cracks in the heat-affected zone. It will also cause weld metal segregation, adversely affect the corrosion resistance of the joint, and cause weld scars.

[0011] After searching, it is found that the existing welding fixtures in the prior art do not have an adjustment component. After the thin copper foils are fixed, the relative position between the two thin copper foils cannot be moved. If there is still a gap between the two thin copper foils after fixation, they need to be re-fixed, which is relatively cumbersome. In addition, since there is no heat dissipation component, the thin copper foil is soft in texture and is easily deformed if it is exposed to high temperature for a long time, resulting in poor use effect. Utility Model Content

[0012] The technical problem to be solved by the utility model is to provide a flexible material welding fixture which is convenient for adjusting the position of a thin copper foil and can cool the thin copper foil.

[0013] In order to solve the above problems, the utility model proposes a technical solution: a flexible material welding fixture, comprising a base connected to a fixing component, the base being connected to an adjusting component and a heat dissipation component, the adjusting component comprising two sliding seats slidably connected to the base, two first screws threadedly connected to the sliding seats, a first driving component is provided between the first screw and the base, the first screw is rotatably connected to the base, the fixing component comprises a base connected to the sliding seat, a fixing plate slidably connected to the base, a second screw threadedly connected to the fixing plate, the sliding seat and the base are connected by bolts and nuts, a second driving component is provided between the second screw and the base, the heat dissipation component comprises a box located at the top of the fixing plate and a fan connected to the box, and an air outlet inclined downward is provided at one end of the box.

[0014] As an improvement, the first driving assembly includes a first worm wheel connected to the first screw, a first worm screw penetrating the base and rotatably connected to the base, the first worm screw meshes with the first worm wheel, and a first hand wheel is provided at the top of the first worm screw.

[0015] As an improvement, the bolt passes through the sliding seat, the base and is threadedly connected with the nut.

[0016] As an improvement, the second drive assembly includes a second worm wheel connected to the second screw, a second worm screw penetrating the base and rotatably connected to the base, the second worm screw meshes with the second worm wheel, and a second hand wheel is provided at one end of the second worm screw.

[0017] As an improvement, the fan is located at the top of the base, and a controller electrically connected to the fan is provided at the top of the base. The fan is connected to the box body through a hose.

[0018] As an improvement, one end of the base is provided with a first sliding groove slidably connected to the sliding seat.

[0019] As an improvement, one end of the base is provided with a second sliding groove slidably connected to the fixing plate.

[0020] The beneficial effects of the utility model are as follows: the utility model can adjust the positional relationship between the two bases through the cooperation of the base and the adjustment component, thereby ensuring that even if the copper foil is not fixed in place, it can be conveniently adjusted without re-fixing;

[0021] The heat dissipation component can promote the flow of air at the welding point, so that the welding point can be cooled down quickly, avoiding the deformation of the copper foil due to long-term high temperature, and the use effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

[0029] A flexible material welding fixture, comprising a base 2 connected to a fixing component, a mounting hole 12 being provided inside the base 2, an adjustment component and a heat dissipation component being connected to the base 2, the adjustment component comprising two slide seats 13 slidably connected to the base 2, two first screw rods 3 threadedly connected to the slide seats 13, and a first slide groove slidably connected to the slide seat 13 being provided at one end of the base 2;

[0030] A first driving assembly is provided between the first screw 3 and the base 2, the first driving assembly comprising a first worm wheel connected to the first screw 3, a first worm 14 penetrating the base 2 and rotatably connected to the base 2, the first worm 14 meshing with the first worm wheel, and a first hand wheel 11 is provided at the top of the first worm 14;

[0031] The first screw rod 3 is rotatably connected to the base 2, and the fixing assembly includes a base 5 connected to the slide 13, a fixing plate 8 slidably connected to the base 5, and a second screw rod 9 threadedly connected to the fixing plate 8. The slide 13 and the base 5 are connected by bolts 4 and nuts. The bolts 4 penetrate the slide 13, the base 5 is threadedly connected to the nut, and the nut is fixed to the slide 13. One end of the base 5 is provided with a second slide groove slidably connected to the fixing plate 8.

[0032] A second driving assembly is provided between the second screw 9 and the base 5, the second driving assembly comprises a second worm wheel connected to the second screw 9, a second worm that penetrates the base 5 and is rotatably connected to the base 5, the second worm is meshed with the second worm wheel, and a second hand wheel 10 is provided at one end of the second worm;

[0033] The heat dissipation assembly includes a box body 7 located at the top of a fixed plate 8 and a fan 1 connected to the box body 7. One end of the box body 7 is provided with an air outlet 6 inclined downward. The fan 1 is located at the top of a base 2. A controller electrically connected to the fan 1 is provided at the top of the base 2 to facilitate control of the fan 1. The fan 1 is connected to the box body 7 by a hose.

[0034] Working principle: Figure 2 As shown, the screw is passed through the mounting hole 12 to connect with the welding machine, and two copper foils to be welded are placed on the two bases 5. The second worm is rotated by the second hand wheel 10, and the second worm drives the second screw 9 to rotate through the second worm gear. The second screw 9 makes the fixing plate 8 move down along the second slide groove until it cooperates with the base 5 to clamp the copper foil. Then, according to the angle between the two copper foils, the base 5 is rotated around the bolt 4 until the sides of the two copper foils approaching each other are parallel. The first worm 14 is rotated by the first hand wheel 11, and the first worm 14 drives the first screw 3 to rotate through the first worm gear. The first screw 3 drives the slide 13 to move, so that the two slides 13 drive the two copper foils to approach each other. Due to the unidirectionality of the worm and worm gear transmission, the first worm gear and the second worm gear can be prevented from rotating by themselves.

[0035] During welding, the fan 1 is started to deliver air to the inside of the box 7. The air is ejected from the downwardly inclined air outlet 6 and causes the air near the welding point to flow quickly, thereby rapidly cooling the welding point and preventing the copper foil from being deformed due to long-term high temperature. The use effect is good.

[0036] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
