Description

Technical Field

[0001] This invention relates to the field of semiconductor lighting device processing technology, specifically to a welding apparatus for semiconductor lighting device processing. Background Technology

[0002] Semiconductor lighting devices possess numerous advantages, including energy saving, environmental friendliness, long lifespan, and excellent color rendering performance, and are currently widely used in fields such as civil lighting, automotive displays, outdoor large screens, and precision backlighting. In the overall production process, the soldering of these devices is a crucial step, requiring specialized soldering equipment.

[0003] While existing welding equipment can perform routine welding operations on semiconductor lighting devices, it faces significant positioning and adaptation issues in practical production applications. Before welding, the semiconductor lighting device to be welded must be clamped and positioned to trigger subsequent welding. However, semiconductor lighting devices are diverse in type and shape, ranging from standard packages like square and round to special shapes such as irregularly shaped substrates and structures with heat sinks, with a wide size range. If a simple two-point clamping mechanism is used, the small clamping contact area and concentrated force points make the workpiece prone to shifting, warping, or even loosening under welding pressure or vibration, leading to defects such as misaligned pads, cold solder joints, and misaligned solder joints, making it difficult to guarantee welding yield. If a multi-point clamping structure is used to improve stability, existing solutions mostly rely on a single drive source for unified control, with the stroke and clamping distance of each clamping point moving synchronously in a fixed ratio. This makes it difficult to independently adjust the clamping stroke and clamping force of each point for workpieces of different shapes, resulting in a very limited range of compatible workpiece sizes. When changing to different specifications of semiconductor lighting devices, it is often necessary to replace the entire set of clamping fixtures and even readjust the equipment parameters. The changeover time is long and the operation is cumbersome, which seriously restricts the applicability and production efficiency of the welding equipment.

The sliding groove 20 is formed in the middle of the four sliding frames 19. The outer surfaces of the four sliding frames 19 are slidably connected to the inner wall of the mounting groove 6. The vertical section of each sliding frame 19 is in a T shape. The rubber pads 21 on the separated sides of the four are fixed to the adjacent sides of the four sliding frames 19. The four sliding frames 19 are distributed in pairs opposite to each other.

[0022] The specific implementation process is as follows: During operation, the semiconductor lighting device is first placed on the base 1. Then, the handwheel 10 is rotated, causing the threaded rod 9, which is fixedly connected to the middle of the handwheel 10, to rotate stably under the limiting constraint of the inner wall of one side of the base 1. The rotating threaded rod 9 drives the slider 7, which is threadedly engaged with its outer surface, to slide along the inner wall of the frame groove 6 opened in the middle of the base 1. The slider 7 simultaneously drives the rack 8 fixed on one side to translate. The translated rack 8 drives the outer gear ring 11 to rotate through tooth meshing. The outer gear ring 11 further drives the fixed disk 12, which is fixedly connected to its inner wall, to rotate together. The fixed disk 12 has several guide grooves 13 circumferentially opened in the middle of the fixed disk 12. Each guide groove 13 has a guide rod 14 slidably engaged in the inner wall of the guide rod 14. The upper end of the guide rod 14 is fixedly connected to one end of the guide block 15. The outer surface of the guide block 15 is slidably engaged in the inner wall of the frame groove 6. When the fixed disk 12 rotates, the four guide grooves 13 drive the four guide rods 14 and the four guide blocks 15 to move towards or away from each other along the limiting direction of the inner wall of the frame groove 6. Each of the four guide blocks 15 has several slots 16 on its upper side. A locking block 17 engages within each slot 16, and a spring 18 is fixedly connected to the upper end of each locking block 17. The upper end of the spring 18 is fixed to the top side of the inner wall of the slide groove 20 in the middle of the sliding frame 19, ensuring that the locking block 17 is always pressed against the slot 16 under the elastic force of the spring 18. When the four locking blocks 17 move from the initial slot 16 position with the guide blocks 15, the two oppositely arranged sliding frames 19 that first contact the workpiece cause their fixed rubber pads 21 to abut against the corresponding side surface of the workpiece, achieving initial positioning. If the corresponding sliding frames 19 on the other two sides also simultaneously abut against the workpiece, clamping is complete. If the corresponding sliding frames 19 on the other two sides have not yet contacted the workpiece, the handwheel 10 can be rotated further. The two sliding frames 19 that have abutted against the workpiece remain stationary, and the corresponding two locking blocks 17 overcome the elastic force of the spring 18 and slide into the next slot 16, until the sliding frames 19 on the other two sides also cause the rubber pads 21 to abut against and clamp the workpiece. If the handwheel 10 is continued to be turned at this point, the elastic force of the four springs 18 must be overcome simultaneously, significantly increasing the rotational resistance, which indicates to the operator that the clamping is in place. Subsequently, the XYZ three-axis motion platform 2, through the mounting bracket 3, drives the soldering iron tip 4 and the solder feeding tube 5 to perform soldering on the workpiece. During reset, the handwheel 10 is turned in the opposite direction to move the four sliding brackets 19 away synchronously. When the rotation is obstructed again, it indicates that the reset is in place. Through the above structure, an adaptive positioning effect is achieved, which can automatically adapt to workpieces of different sizes and shapes. Whether it is a square, round, or irregularly shaped semiconductor lighting device, it can be stably clamped through the adaptive feed of the four-sided grippers. There is no need to change the clamping fixture separately for different specifications of workpieces, nor is there a need to manually adjust the stroke and position of each gripper one by one, saving tedious debugging steps, thereby improving the applicability and production efficiency of the welding device.

[0023] Example 2 After the welding equipment completes the welding of semiconductor lighting devices, the thin and lightweight substrates of these devices, along with the tendency for negative pressure adsorption or solder adhesion to form between the device and the fixture after welding, make it difficult for operators to directly and smoothly remove the devices from the positioning fixture. This results in low material handling efficiency and a high risk of device damage from impacts. Therefore, it is necessary to incorporate a lifting mechanism into the welding equipment to smoothly lift the finished semiconductor lighting devices from the positioning fixture to a certain height, facilitating material handling by operators or robotic arms and improving the ease of operation and reliability of material handling within the welding equipment.

[0024] Please see Figures 1-8 As shown, an automatic lifting function has been added based on Embodiment 1; Please refer to it again. Figures 1-8 As shown, a limiting groove 25 is provided on the upper side of the frame groove 6. Extrusion frames 22 are slidably connected to the inner walls on both sides of the limiting groove 25. Extrusion blocks 23 are slidably connected to the outer surfaces of the two extrusion frames 22. Limiting blocks 24 are fixed at both ends of the extrusion blocks 23. The limiting groove 25 passes through the upper side of the base 1. The outer surfaces of the two extrusion frames 22 are slidably connected to the inner walls on both sides of the limiting groove 25. The contact sides of the two extrusion frames 22 and the extrusion blocks 23 are both arc-shaped. The two ends of the extrusion blocks 23 are fixed to the near ends of the two limiting blocks 24. The outer surface of the extrusion blocks 23 and the outer surfaces of the two limiting blocks 24 are slidably connected to the inner wall of the limiting groove 25. The extrusion blocks 23 are rectangular with a hollow center.

[0025] The specific implementation process is as follows: During operation, the handwheel 10 is manually rotated, causing the threaded rod 9, which is fixedly connected to the middle of the handwheel 10, to rotate stably under the limiting constraint of the inner wall on one side of the base 1; the rotating threaded rod 9 is driven by the slider 7 and the rack 8, causing the outer gear ring 11 and the fixed plate 12 to rotate synchronously; the fixed plate 12, through the sliding cooperation of the four guide grooves 13 on it with the four guide rods 14, drives the four guide blocks 15 fixedly connected to the upper end of the four guide rods 14 to move towards or away from each other along the frame groove 6. When the four guide blocks 15 complete the clamping and move in opposite directions and away from each other, two of the guide blocks 15 that are arranged opposite each other will... During the movement to the farthest position, the two extrusion frames 22 are extruded respectively, causing the two extrusion frames 22 to move away from each other under the limiting constraint of the inner wall of the limiting groove 25 opened on the upper side of the frame groove 6; the two extrusion frames 22 moving away from each other extrude the corresponding arc surfaces on both sides of the extrusion block 23 through the arc surface on the other side, causing the extrusion block 23 to move vertically under the limiting constraint of the inner wall of the limiting groove 25; during the upward movement, the limiting blocks 24 fixed at both ends of the extrusion block 23 slide and engage with the inner wall of the limiting groove 25, so that the extrusion block 23 is always restricted to move vertically within the limiting groove 25, avoiding deviation or dislodgement; The upward-moving extrusion block 23 lifts the workpiece placed on it, raising it to a certain height. When the guide block 15 moves in the opposite direction and no longer applies extrusion force to the extrusion frame 22, the extrusion block 23 falls back to its original position under its own gravity, and then moves back to its original position by pressing the two extrusion frames 22 towards each other through the arc-shaped surfaces on both sides. Through the above structure, an automatic lifting effect is achieved after welding, smoothly lifting the processed semiconductor lighting device from the positioning fixture to a certain height, facilitating material handling by operators or robotic arms, and effectively improving the ease of operation and reliability of material handling of the welding device.

[0026] Example 3 After the welding equipment completes the processing of semiconductor lighting devices, it can only rely on natural convection to cool the welding area. The time required for solder solidification and cooling of the solder joints is relatively long, severely restricting the processing cycle of a single station. If the material is removed prematurely before the solder joints have fully cooled and solidified, it can easily lead to quality defects such as solder joint deformation, cold solder joints, or even solder pad detachment. Therefore, it is necessary to install a forced air cooling structure near the welding station to accelerate local air circulation in the welding area, thereby shortening the cooling time and improving the welding quality and overall work efficiency of the welding equipment.

[0027] Please see Figures 1-8 As shown, a forced air cooling acceleration function has been added based on Embodiment 1; Please refer to it again. Figures 1-8 As shown, each of the two extrusion frames 22 has a fixing block 26 fixed at its disjoint end, and a sliding plate 27 fixed at the other end of each of the two fixing blocks 26. Both sliding plates 27 have air boxes 28 slidably connected to their outer surfaces. Each air box 28 has an air trough 29 in its middle, and several air guide holes 30 are provided at the upper end of each air trough 29. The two fixing blocks 26 are fixed at their proximal ends to the disjoint ends of the two extrusion frames 22, and at their disjoint ends to the lower ends of the two sliding plates 27. The two fixing blocks 26 penetrate the proximal sides of the two air boxes 28. The outer surfaces of the two sliding plates 27 are slidably connected to the inner walls of the two air troughs 29. The two air troughs 29 penetrate the lower sides of the two air boxes 28. Several air guide holes 30 penetrate the proximal sides of the two air boxes 28, and each air guide hole 30 has a V-shaped cross-section. The two air boxes 28 are arranged opposite each other.

[0028] The specific implementation process is as follows: By manually rotating the handwheel 10, the threaded rod 9, which is fixedly connected to the middle of the handwheel 10, rotates stably under the limiting constraint of the inner wall on one side of the base 1; the rotating threaded rod 9 is driven by the slider 7 and the rack 8, which drives the outer gear ring 11 and the fixed plate 12 to rotate synchronously; the fixed plate 12 drives the four guide blocks 15, which are fixedly connected to the upper end of the four guide rods 14, to move towards or away from each other along the frame groove 6 through the sliding cooperation of the four guide grooves 13 opened on it. When the four guide blocks 15 complete clamping and move in opposite directions and away from each other, two of the guide blocks 15 that are arranged opposite each other will squeeze the two extrusion frames 22 during the movement, so that the two extrusion frames 22 are separated from each other by the inner wall of the limiting groove 25 opened on the upper side of the frame groove 6. The two extrusion frames 22 that are separated from each other will drive the two fixed blocks 26 that are fixedly connected to their separated ends to move synchronously. The two fixed blocks 26 will further drive the two slide plates 27 that are fixedly connected to their separated ends to slide along the inner wall of the air groove 29 opened in the middle of the air box 28 fixed on both sides of the base 1. As the two slide plates 27 move away from each other within the air duct 29, they compress the air within the air duct 29, causing the air to be blown out through the air guide holes 30 connected to the air duct 29. The blown airflow directly acts on the welding station, accelerating the local airflow speed in the welding area, thereby achieving a forced air cooling acceleration effect. This effectively shortens the cooling time of the solder joint, allowing the solder to solidify quickly and avoiding defects such as solder joint deformation, spikes, and cold solder joints caused by slow cooling. At the same time, it reduces the thermal impact of welding residual heat on the internal components, improving the welding quality and overall working efficiency of the welding device.
