Description

Technical Field

[0001] This utility model relates to the field of copper foil flexible connection welding technology, specifically a copper foil flexible connection welding fixture. Background Technology

[0002] Copper foil is a cathodic electrolytic material, a thin, continuous metal foil deposited on the substrate layer of a circuit board. As a conductor in the PCB, it easily adheres to the insulating layer, receives the printed protective layer, and forms a circuit pattern after etching. When making flexible connections between copper foils, it is often necessary to place the copper foil pieces to be soldered in a fixture and use a soldering head to solder the two copper foils.

[0003] In existing technologies, when using a fixture to weld copper foil flexible connections, the copper foil needs to be placed manually, which is prone to misalignment. Some fixtures use clamps in the fixture to limit the copper foil, but these are mostly fixed clamps that lack fine-tuning capabilities, resulting in insufficient positioning stability and accuracy. This leads to a high rate of welding misalignment. Furthermore, the fixture has poor heat dissipation efficiency, and the high welding temperature can easily cause the copper foil to anneal, reducing its conductivity. During cooling, manual cooling of the welded copper foil is also required, which is inefficient. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] A copper foil flexible connector welding fixture, such as Figures 1-6As shown, the system includes a base 1, with a bracket 2 and a cooling seat 5 fixedly mounted on the upper surface of the base 1. Two movable seats 6 are sleeved on the outside of the cooling seat 5, and the bottom ends of the two movable seats 6 are slidably connected to the base 1. Each of the two movable seats 6 is equipped with a positioning mechanism. A cylinder 3 is mounted on the upper surface of the bracket 2, and a welding head 4 is fixedly connected to the bottom end of the cylinder 3. Cylinders 7 are mounted on both outer walls of the base 1, and the output end of cylinder 7 is fixedly connected to the movable seat 6. The positioning mechanism includes a bearing seat 8, which is slidably connected to the bottom of the movable seat 6. Two clamping plates 13 are slidably connected inside the bearing seat 8, and a rotating shaft 15 is rotatably connected inside each of the two clamping plates 13. A limit plate 14 is fixedly connected to the outer wall of the rotating shaft 15.

[0030] Among them, cylinder 3 has the model number DSNU-25-60-PPV-A.

[0031] The bottom end of the limiting plate 14 is rotatably connected to the pressure roller 17 via a shaft. The outer side of the rotating shaft 15 is fitted with tension springs 16 near both ends. One end of the tension spring 16 is fixedly connected to the rotating shaft 15, and the other end of the tension spring 16 is fixedly connected to the inner wall of the clamping plate 13. When the limiting plate 14 is rotated, the tension spring 16 deforms. Subsequently, under the action of the rebound force of the tension spring 16, the limiting plate 14 can cooperate with the pressure roller 17 to press and position the copper foil. By pressing the copper foil down by the pressure roller 17, wrinkling of the copper foil can be avoided.

[0032] The positioning mechanism also includes a crossbar 18, a threaded screw 9, and a movable rod 10. The crossbar 18 is fixedly connected to the bottom of the bearing seat 8. Two sliders 19 are sleeved on the outside of the crossbar 18, and the upper ends of the two sliders 19 are fixedly connected to two clamping plates 13 respectively. Spring plates 20 are sleeved on the outside of the sliders 19 near both ends, and one end of the spring plate 20 is fixedly connected to the slider 19, and the other end of the spring plate 20 is fixedly connected to the inner wall of the bearing seat 8. When the two clamping plates 13 are moved, they are separated from each other, and the spring plates 20 are compressed and contracted. Then, the copper foil is placed in. At this time, the clamping plates 13 are released, and the spring plate 20 rebounds, causing the clamping plates 13 to clamp the copper foil. Through the tension spring 16 and the limiting plate 14, the pressure roller 17 presses against the surface of the copper foil, thus completing the positioning of the copper foil.

[0033] The movable rod 10 is movably inserted into the outer wall of the movable seat 6, and the threaded rod 9 is rotatably connected to the outer wall of the movable seat 6. A threaded rod sleeve 11 is sleeved on the outside of the threaded rod 9, and a connecting block 12 is fixedly connected to the outer wall of the threaded rod sleeve 11. The connecting block 12 is fixedly connected to the movable rod 10, and one end of the movable rod 10 is fixedly connected to the bearing seat 8.

[0034] In use, firstly, the two clamping plates 13 are separated. The slider 19 slides along the crossbar 18 following the clamping plates 13. The spring plate 20 is compressed and contracted. Then, the copper foil to be welded is placed inside the bearing seat 8 and positioned between the two clamping plates 13. Then, the clamping plates 13 are released. Under the action of the spring plate 20's rebound force, the two clamping plates 13 move closer to each other to clamp and fix the copper foil. At the same time as separating the two clamping plates 13, the limiting plate 14 is rotated through the rotating shaft 15, so that the pressure roller 17 moves away from the bottom of the bearing seat 8. After the copper foil is clamped and fixed on both sides, the limiting plate 14 is released. Under the action of the rebound force of the two tension springs 16, the limiting plate 14 can be rotated, so that the pressure roller 17 is pressed down to the upper surface of the copper foil to further position and fix the copper foil, achieving double-stage locking.

[0035] After it is fixed, the screw rod 9 is rotated to drive the screw sleeve 11 to move, thereby driving the connecting block 12 to move, which can drive the movable rod 10 to move, so that the bearing seat 8 slides in the movable seat 6. This allows for fine adjustment of the position of the copper foil piece positioned in the bearing seat 8, improving the accuracy of the position after it gets close to another copper foil piece.

[0036] Similarly, another copper foil can be positioned and fixed. At this time, the two movable seats 6 can be brought closer together by the cylinder 7, so that the two copper foils come into contact and are precisely aligned. Then, the welding head 4 can be moved down by the cylinder 3 to perform welding operations on the two copper foils.

[0037] Among them, cylinder 2, model 7 is DSNU-25-60-PPV-A.

[0038] The cooling base 5 has a circulation pipe 27 fixedly installed inside. A liquid pump 28 and a liquid pump 31 are set on one side of the base 1. One end of the liquid pump 28 and the liquid pump 31 are fixedly connected to a connecting pipe 29. The other end of the liquid pump 28 and the liquid pump 31 are fixedly connected to a connecting pipe 30. One end of the two connecting pipes 29 is fixedly connected to both ends of the circulation pipe 27. Switch buttons 24 are set on both inner walls of the bracket 2. The output ends of the two switch buttons 24 are connected to the input ends of the liquid pump 28 and the liquid pump 31, respectively. Cooling water can enter the connecting pipe 29 through the connecting pipe 30 in conjunction with the liquid pump 28 and flow into the circulation pipe 27. The circulation pipe 27 is in close contact with the inner wall of the cooling base 5. The materials of the cooling base 5, the movable base 6, the bearing base 8 and the limiting plate 14 are all heat-resistant metal materials with excellent thermal conductivity, which can effectively exchange and cool the heat generated during welding.

[0039] An L-shaped movable plate 22 is fixedly connected to the outer wall of the welding head 4. Vertical rods 26 are fixedly installed on the two inner walls of the bracket 2. Two sliding plates 25 are fitted on the outside of the two vertical rods 26. Movable blocks 21 are slidably connected to the outer walls of the two sliding plates 25, and the movable blocks 21 are slidably connected to the L-shaped movable plate 22. Spring pieces 23 and two return springs are fitted on the outside of the two vertical rods 26. The return springs are used to assist in the reset of the spring pieces 23 after they have been squeezed and deformed. The spring pieces 23 are fitted on the vertical rods 26 and maintain a pre-contact state with the switch buttons 24. The two switch buttons 24 are embedded in the side wall of the bracket 2 and are connected to the control terminals of the first liquid pump 28 and the second liquid pump 31 through wires.

[0040] Specifically, when the welding head 4 moves downward to perform the welding operation, the L-shaped movable plate 22 moves downward as well, pushing the movable block 21 and the sliding plate 25 to compress the two spring pieces 23. This causes the two spring pieces 23 to deform, triggering the two switch buttons 24 to start the first liquid pump 28 and the second liquid pump 31. This allows the coolant to be pumped into the circulation pipe 27 through the connecting pipe 29 on the first liquid pump 28, and the coolant in the circulation pipe 27 is pumped out through the connecting pipe 29 and the connecting pipe 30 on the second liquid pump 31. This allows the coolant to circulate in the circulation pipe 27, exchanging heat with the cooling seat 5, thereby cooling the heat generated during welding. After welding is completed, the welding head 4 moves upward, and the L-shaped movable plate 22 moves upward. Similarly, the switch button 24 can be turned off, causing the first liquid pump 28 and the second liquid pump 31 to stop working. This effectively prevents the high temperature of welding from causing the copper foil grains to coarsen, which would lead to a decrease in the conductivity of the copper foil.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
