Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing technology, and in particular to a flexible copper-clad laminate connection point welding device. Background Technology

[0002] A flexible copper-clad laminate (CCL) connection point welding equipment is a key piece of equipment for achieving high-precision connections in the electronics manufacturing industry. Its core function is to complete reliable electrical connections of micron-level circuits and components on flexible substrates through precision welding technology. The equipment adopts non-contact processes such as laser soldering and ultrasonic welding to control the heat-affected zone within a small area, avoiding mechanical damage and thermal deformation of the flexible CCL substrate caused by traditional contact welding. Laser soldering technology achieves precise operation through micron-level spot focusing, while ultrasonic welding utilizes high-frequency vibration to complete cold welding at low temperatures, meeting the welding requirements of ultra-thin substrates. The equipment integrates multi-axis motion control, visual positioning, and real-time parameter monitoring functions to improve production efficiency and welding consistency.

[0003] A flexible copper-clad laminate connection point welding equipment mainly consists of the following structures: a welding execution module including a laser welding head or an ultrasonic welding module, the former realizing dynamic power adjustment, and the latter equipped with a 3D floating welding head to compensate for height differences; a multi-axis motion platform adopting a marble gantry structure, with servo motors to ensure repeatability and positioning accuracy; visual positioning consisting of a high-pixel camera and algorithms to quickly complete pad calibration; intelligent tooling fixtures supporting rapid changeover and adaptive clamping; integrated control with real-time monitoring and algorithms to optimize the welding path; and auxiliary modules including fume absorption and nitrogen protection to purify exhaust gas and inhibit solder oxidation. All structures work together to meet complex welding requirements.

[0004] In existing technologies, the lack of a dedicated clamping device during welding can easily lead to displacement or warping of the flexible substrate. Mechanical vibration, airflow disturbance, and thermal stress during welding can cause slight displacement of the unfixed copper-clad laminate, resulting in the solder joint deviating from the preset position, reducing connection accuracy, affecting the electrical conductivity and mechanical strength of the solder joint, reducing production efficiency, and causing poor product consistency and high rework rate during mass production. Therefore, a flexible copper-clad laminate connection point welding device is proposed to solve the above problems. Utility Model Content

[0011] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figures 1 to 3This utility model provides an embodiment of a flexible copper-clad laminate connection point welding device, including a base plate 1. A support block 2 is fixedly connected to the top of the base plate 1, serving as the basic load-bearing structure of the device and providing a stable installation platform for the entire device, avoiding the impact of foundation shaking on welding accuracy. A clamping mechanism 3 is installed inside the support block 2, providing installation space and support for components such as the motor 301 and the limit rod 303 of the clamping mechanism 3. At the same time, the top of the support block 2 carries the limit component 307 to ensure the stability of the clamping operation. A control box 4 is fixedly connected to the top of the base plate 1 for overall control and parameter adjustment of the device, and also provides support for a second control box 5, integrating the control functions of the device. The front side of the control box 4 is fixedly connected to the second control box 5 for overall control and parameter adjustment of the device, and also provides support for the second control box 5, integrating the control functions of the device. A cleaning mechanism 6 is installed inside the second control box 5 for cleaning the welding area. The clamping mechanism 3 includes a motor 301, which is used to fix the flexible copper-clad laminate to prevent displacement or warping during welding. The outer wall of the motor 301 is fixedly connected to the inner wall of the support block 2. The drive end is connected to a gear 302, which is the power source of the clamping mechanism 3. The drive end of the motor 301 is fixedly connected to the gear 302. The output torque drives the gear 302 to rotate, thereby driving the rack 305 to move, realizing the opening and closing of the clamping pad 3073 and controlling the clamping force. The inner wall of the support block 2 is fixedly connected to two limit rods 303, which are fixed to the inner wall of the support block 2. The outer wall is slidably connected to a connecting block 304. The outer walls of the two limit rods 303 are slidably connected to the connecting blocks 304 to ensure that they slide only in a straight line, avoid the rack 305 from deviating, and ensure the stability of the meshing between the gear 302 and the rack 305. A rack 305 is fixedly connected to the outer wall of the connecting block 304, connecting the rack 305 and the clamping pad 3073, transmitting the power of the rack 305 to the clamping pad 3073. At the same time, the movement is kept stable under the constraint of the limiting rod 303. A spring 306 is sleeved on the outside of the rack 305, which moves linearly under the drive of the gear 302. The connecting block 304 drives the clamping pad 3073 to move, realizing the clamping or loosening action. It is a key component for power transmission. A limiting component 307 is set at the top of the support block 2 to limit the placement position of the copper-clad laminate. The clamping pad 3073 directly contacts and fixes the substrate, and the clamping mechanism 3 improves the positioning accuracy.

[0013] Reference Figure 3The limiting component 307 includes a slide rail 3071, the bottom of which is fixed to the top of the support block 2. The outer wall is slidably connected to a clamping pad 3073. The bottom of the slide rail 3071 is fixedly connected to the top of the support block 2, providing a sliding track for the clamping pad 3073 to ensure that the clamping pad 3073 moves in a straight line, ensuring that the copper-clad laminate is subjected to uniform force when clamped and avoiding deviation. The front and rear sides of the slide rail 3071 are fixedly connected to baffles 3072 to limit the sliding range of the clamping pad 3073 and prevent the clamping pad 3073 from falling off the slide rail 3071. At the same time, the front and rear positions of the copper-clad laminate are limited to improve the placement accuracy. The outer wall of the slide rail 3071 is slidably connected to two clamping pads 3073, which are made of flexible material. When clamped, they increase the friction with the substrate to prevent slippage and avoid rigid contact that could damage the surface of the copper-clad laminate, thus protecting the integrity of the substrate.

[0014] Reference Figures 2 to 4 The cleaning mechanism 6 includes a second motor 601, which drives a turntable 602, a rotating arm, and other components to move the nozzle 7, achieving precise cleaning of the welding points, removing impurities, and ensuring welding quality. The outer wall of the second motor 601 is fixedly connected to the inner wall of the second control box 5. The drive end of the motor 601 is connected to the turntable 602, providing power to the cleaning mechanism 6 and outputting rotational motion to drive the turntable 602 to rotate. This power is then transmitted through the rotating arm to achieve the reciprocating movement of the nozzle 7. A rotating arm 603 is fixedly connected to the front side of the turntable 602, converting the rotational motion of the second motor 601 into the oscillation of the rotating arm 603. The first rotating arm 603 is rotatably connected to the second rotating arm 604, which provides power for the movement of the nozzle 7. The second rotating arm 604 is rotatably connected to the outer wall of the first rotating arm 603, which transmits the power of the turntable 602 to the second rotating arm 604. The direction and amplitude of the force transmission are changed by the length design, so as to realize the reciprocating motion of the sliding block 605. The front side of the second rotating arm 604 is rotatably connected to the sliding block 605, which converts the swing of the first rotating arm 603 into the linear motion of the sliding block 605. The hinge structure adapts to the change of the motion direction and ensures the continuity of power transmission. The front side of the sliding block 605 is fixedly connected to the sliding plate 606, which slides along the second sliding rail 607 under the drive of the second rotating arm 604, and transmits the power to the sliding plate 606, which drives the nozzle 7 to move. A slide rail 607 is fixedly connected to the inner wall of control box 2 5. A sliding block 605 is slidably connected to the outer wall of control box 2 5. The outer wall of the sliding block 605 is slidably connected to the outer wall of slide rail 607, restricting the movement direction of the sliding block 605 and ensuring it slides in a straight line. This prevents the sliding plate 606 and nozzle 7 from shifting, ensuring the accuracy of the cleaning position. The outer wall of the sliding plate 606 is slidably connected to the inner wall of control box 2 5 and fixed to the front side of control box 1 4. A cleaning mechanism 6 is installed inside. Slide rail 607 is fixed to the inner wall. A nozzle 7 is fixedly connected to the front side of the sliding plate 606. Driven by the sliding block 605, the nozzle 7 moves in a straight line, causing it to move synchronously, expanding the cleaning range and ensuring that impurities around the welding point are removed. Connecting block 30... The outer wall of the 4 is slidably connected to the inner wall of the support block 2, and slidably connected to the limit rod 303 and the inner wall of the support block 2. The outer wall is fixed with racks 305. The outer sides of the two racks 305 are meshed with the outer sides of the gears 302. The 4 is fixed to the outer wall of the connecting block 304 and meshes with the gears 302. The outer side is fitted with springs 306. The adjacent sides of the two springs 306 are fixedly connected to the inner wall of the support block 2 and fitted to the outer side of the racks 305. The two ends are respectively connected to the inner wall of the support block 2 and the connecting block 304. The distant sides of the two springs 306 are fixedly connected to the adjacent sides of the two connecting blocks 304. When clamped, the springs provide a buffer force to avoid excessive pressure on the clamping pads 3073 and damage to the copper-clad laminate. When released, the springs assist the connecting block 304 to reset and improve the response speed of the mechanism.

[0015] Working principle: After the motor 301 starts, its drive end drives the gear 302 to rotate clockwise. Since both racks 305 are engaged with the gear 302 and are constrained by the limiting rod 303 to slide only in a straight line, the two racks 305 will move away from each other, thereby driving the connecting block 304 to move synchronously. At this time, the connecting block 304 pulls the spring 306 sleeved outside the racks 305, causing the spring 306 to be stretched. At the same time, the connecting block 304 drives the two clamping pads 3073 in the limiting component 307 to slide away from each other along the slide rail 3071. They are restricted by the baffle 3072 and do not fall off. The clamping device opens, and the flexible copper-clad laminate can be placed in. Conversely, if the motor 301 drives the gear 302 to rotate counterclockwise, the two racks 305 move closer to each other, the spring 306 retracts and resets, and the connecting block 304 drives the clamping pads 3073 to move closer to each other along the slide rail 3071 until the copper-clad laminate is clamped, preventing displacement during soldering.

[0016] After motor 2 601 starts, its drive end drives turntable 602 to rotate. Rotating arm 1 603 on the front side of turntable 602 rotates synchronously with it. When rotating arm 1 603 moves from the front side to the rear side, it pulls rotating arm 2 604 in conjunction, causing rotating arm 2 604 to drive sliding block 605 to slide backward along slide rail 2 607. Sliding block 605 then drives sliding plate 606 to slide backward along the inner wall of control box 2 5. The nozzle 7 on the front side of sliding plate 606 moves backward to clean the rear side of the welding area. Conversely, when rotating arm 1 603 moves from the rear side to the front side, it pushes rotating arm 2 604 in conjunction, causing sliding block 605 to slide forward along slide rail 2 607, driving sliding plate 606 and nozzle 7 to move forward to clean the front side of the welding area. Through reciprocating motion, the welding area is thoroughly cleaned.

[0017] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
