Description

Technical Field

[0001] The present invention relates to the technical field of LED lamp bead substrate welding, and specifically refers to a substrate welding device suitable for LED lamp beads. Background Art

[0002] Currently, the substrate welding process of LED lamp beads mainly relies on manual operation or semi-automatic equipment. Manual operation has problems such as low production efficiency, easy occurrence of human errors, and difficulty in ensuring production stability; although traditional semi-automatic equipment has improved production efficiency to a certain extent, there are still problems such as inconsistent production beats, numerous intermediate links, and low thermal energy utilization rate.

[0003] In the prior art, it is usually necessary to install and transport the substrate multiple times to different devices for operations such as solder paste coating, LED lamp bead placement, and welding, resulting in low production efficiency, difficult to fully guarantee the welding quality, wasting a large amount of energy. In addition, when welding the substrate of LED lamp beads, multiple steps of manual operation are required, which easily causes the problem of inconsistent beats, affecting the overall production efficiency. A large amount of heat generated during the welding process is seriously wasted and not effectively utilized, which not only increases the production cost but also is not conducive to environmental protection. Affected by manual operation, the welding quality is difficult to be stable, increasing the rejection rate during the production process and the subsequent inspection cost.

[0016] 2. In the present invention, through the side positioning frames and the front positioning frames arranged around the top of the feeding rack, for substrates of different shapes, such as rectangles, squares, circles, etc., central positioning can be achieved by flexibly adjusting the positioning frames in four directions, enabling the LED lamp bead substrate welding equipment to adapt to the production of various types of LED lamp bead substrates, without the need to replace special positioning devices for different-shaped substrates, reducing the complexity and production cost of the equipment, and improving the adaptability and flexibility of the equipment; at the same time, by using the limit blocks arranged on the two side positioning frames, when positioning the arc-shaped substrate, the limit blocks can effectively limit both sides of the arc-shaped substrate, preventing it from shifting or shaking due to its own shape characteristics during the welding process, greatly improving its stability during the processing.

Through precise motion control, the hot air gun can accurately aim at the solder paste between the LED lamp beads and the substrate for heating and welding, enabling the solder paste to quickly melt and form a good welding connection. At the same time, by precisely controlling parameters such as the hot air temperature and wind speed, it can adapt to different types of LED lamp beads and substrate materials, ensuring the reliability and stability of the welding quality.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0028] Embodiment 1:

[0029] Please refer to Figures 1 to 6 As shown, the substrate welding device applicable to LED lamp beads includes a welding frame 1 and a feeding frame 2. A welding chamber is provided inside the welding frame 1, and a feeding frame 2 is fixedly provided on the front side inside the welding frame 1. A feeding component is provided below the inside of the welding chamber, and a welding component is provided above the inside of the welding chamber. An electric slide table five 23 is fixedly provided on the front surface of the welding frame 1, and feeding components are slidably provided on both sides of the front surface of the electric slide table five 23.

[0030] It should be noted that during the substrate welding process of LED lamp beads, the LED lamp beads are automatically fed through the feeding frame 2. The feeding components on both sides of the front surface of the electric slide table five 23 cooperate to automatically feed the LED lamp beads on the feeding frame 2 into the inside of the feeding component. The feeding component is used to position and clamp the substrate, and the welding component is used to apply solder paste to several pins on the substrate. Then, several LED lamp beads are respectively placed above several pins. Finally, the welding component performs hot air welding on the solder paste coated between several LED lamp beads and the pins, and at the same time, the excess heat during the hot air welding process is recycled to improve the utilization rate of heat during the welding process of the LED substrate.

[0031] In a specific embodiment, in the present invention, the feeding components on both sides of the front surface of the electric slide table five 23 cooperate with the feeding frame 2 to efficiently and automatically transport the LED lamp beads into the inside of the feeding component, realizing a continuous and fast feeding process, improving the coherence and overall efficiency of production, and further reducing the errors and uncertainties brought by manual operations, ensuring the stability of the production rhythm; the welding component provided inside the welding chamber cooperates with the feeding component to sequentially complete a series of operations such as pin solder paste coating, LED lamp bead placement, and final hot air welding, without the need for frequent transfer and adjustment between different devices or processes, reducing the time waste and possible errors in the intermediate links, and further improving the production efficiency and the stability of product quality.

[0032] Specifically, the feeding component includes a feeding rack 3. The feeding rack 3 is fixedly arranged at the bottom inside the welding chamber, and electric sliding tables 1 are fixedly arranged around the top of the feeding rack 3. A positive positioning rack 6 is slidably arranged on the top of the two electric sliding tables 1 on the front and rear sides, and a side positioning rack 5 is slidably arranged on the top of the two electric sliding tables 1 on the left and right sides. Two electric sliding tables 2 are fixedly arranged on one side of the two opposite side positioning racks 5, and a limiting block 8 is slidably arranged on one side of the electric sliding tables 2 on both sides.

[0033] It should be noted that when placing the substrate, place the substrate on the top of the feeding rack 3, and then control the side positioning racks 5 on the left and right sides to clamp and position the left and right sides of the substrate through the electric sliding tables 1 around. At the same time, use the two positive positioning racks 6 on the front and rear sides to clamp and position the front and rear sides of the substrate. Center positioning of substrates with different shapes is performed on the top of the feeding rack 3 through the two side positioning racks 5 on the left and right sides and the two positive positioning racks 6 on the front and rear sides, which facilitates subsequent placement of LED lamp beads on the substrate and application of solder paste on several pins, and can greatly improve the welding processing efficiency between the LED lamp beads and the substrate. In addition, when positioning the arc-shaped substrate, the limiting blocks 8 arranged on the side positioning racks 5 on the left and right sides limit the two sides of the arc-shaped substrate to ensure the stability of the arc-shaped substrate during the welding process.

[0034] In a specific embodiment, in the present invention, through the side positioning racks 5 and positive positioning racks 6 arranged around the top of the feeding rack 3, for substrates with different shapes, such as rectangles, squares, circles, etc., center positioning can be achieved by flexibly adjusting the positioning racks in four directions, enabling the LED lamp bead substrate welding equipment to adapt to the production of various types of LED lamp bead substrates without the need to replace dedicated positioning devices for different-shaped substrates, reducing the complexity and production cost of the equipment, and improving the adaptability and flexibility of the equipment. At the same time, by using the limiting blocks 8 arranged on the two side positioning racks 5, when positioning the arc-shaped substrate, the limiting blocks 8 can effectively limit the two sides of the arc-shaped substrate, preventing it from shifting or shaking due to its own shape characteristics during the welding process, greatly improving its stability during the processing. Through reliable positioning and clamping, the substrate remains stable throughout the welding process, ensuring the stability and consistency of the welding process. This not only improves the quality of the product but also reduces subsequent inspection and repair work due to quality problems, further improving production efficiency and economic benefits.

And the interior of the molten material tank 22 is communicated with the interior of the paste applying head 18 through a feeding hose.

[0037] Furthermore, at the bottom of the closed frame 9, a connecting convex block 10 is fixedly arranged. And around the top of the material placing frame 3, connecting grooves 11 matching with the connecting convex block 10 are arranged.

[0038] It should be noted that when applying solder paste to a plurality of pins on the substrate, the driving end of the servo cylinder II 21 is used to control the downward movement of the closed frame 9 until the connecting convex block 10 at the bottom of the closed frame 9 cooperates with the connecting groove 11 at the top of the material placing frame 3 to close the top of the material placing frame 3. Then, the electric slide III 12 is used to drive the movable frame 13 to slide left and right inside the closed frame 9, and the electric slide IV 14 at the bottom of the movable frame 13 is used to control the sliding of the rear movable block 15. The driving end of the servo cylinder I 16 is used to control the downward movement of the paste applying head 18, and the paste applying head 18 is used to perform solder paste coating treatment on a plurality of pins on the substrate. Then, the LED lamp beads are placed on the plurality of pins on the substrate by the feeding assembly. Finally, the front movable block 15 at the bottom of the movable frame 13 is used to slide, and the hot air gun 20 arranged at the bottom end of the driving end of the movable block 15 is used to perform hot air welding treatment on the solder paste between the LED lamp beads and the substrate.

[0039] In a specific embodiment, the rotation motor 17 is provided in the present invention so that the first servo cylinder 16 can rotate at a certain angle, which further increases the operation flexibility of the paste applicator head 18. When facing pins at different angles or positions, the paste applicator head 18 can be rotated to the optimal coating angle to ensure that the solder paste can be accurately and evenly coated on the pins; after placing the LED lamp beads, the hot air gun 20 provided at the bottom of the movable block 15 is used for hot air welding. Through precise motion control, the hot air gun 20 can accurately align with the solder paste between the LED lamp beads and the substrate for heating and welding, enabling the solder paste to quickly melt and form a good welding connection. At the same time, by precisely controlling parameters such as the hot air temperature and wind speed, it can adapt to different types of LED lamp beads and substrate materials, ensuring the reliability and stability of the welding quality.

[0040] Embodiment 3:

[0041] Specifically, the feeding assembly includes a sliding frame 24 and a connecting frame 26. The sliding frame 24 is slidably arranged on the front surface of the fifth electric slide table 23, and servo cylinders three 25 are fixedly arranged on both sides inside the sliding frame 24. The top ends of the driving ends of the two servo cylinders three 25 are fixedly provided with a connecting frame 26, and servo cylinders four 27 are fixedly arranged on both sides inside the connecting frame 26. The driving ends of the two servo cylinders four 27 are fixedly provided with a control frame 28, and a control motor 29 is fixedly arranged on the front surface of the control frame 28. A feeding frame 30 is rotatably arranged on the back surface of the control frame 28, and the inside of the feeding frame 30 is fixedly connected to one end of the output shaft of the control motor 29. An electric slide table six 31 is fixedly arranged at the top of the inner wall of the feeding frame 30, and a plurality of micro cylinders 32 are slidably arranged at the bottom of the electric slide table six 31. The bottom ends of the driving ends of the plurality of micro cylinders 32 are fixedly provided with adsorption blocks 33.

[0042] It should be noted that when feeding the LED lamp beads on the feeding rack 2, the height of the feeding rack 30 is controlled by the driving end of the servo cylinder three 25, and the position of the feeding rack 30 is controlled by the driving end of the servo cylinder four 27 to be transferred from above the feeding rack 2 to above the discharging rack 3. When the feeding rack 30 is above the feeding rack 2, the adsorption blocks 33 provided at the driving ends of the plurality of micro cylinders 32 inside the feeding rack 30 are used to adsorb the LED lamp beads on the top of the feeding rack 2. Then, the adsorption blocks 33 provided at the driving ends of the plurality of micro cylinders 32 transfer the LED lamp beads to the substrate on the top of the discharging rack 3, realizing the automatic feeding operation of the LED lamp beads. And when placing the LED lamp beads on the arc-shaped substrate, the feeding rack 30 is controlled to rotate by the output shaft of the control motor 29 arranged on one side of the control frame 28, and the LED lamp beads can be accurately placed on the substrate in cooperation with the micro cylinders 32 and the adsorption blocks 33, realizing the automatic feeding and positioning operation between the LED lamp beads and the substrate, greatly improving the welding processing efficiency between the LED lamp beads and the substrate.

[0043] Furthermore, a heat exchange tank 34 is provided inside the unloading rack 3, and the interior of the heat exchange tank 34 is connected to the interior of the melt tank 22 through a circulating fan. The heat exchange tank 34 is used to send excess heat during the welding process to the interior of the melt tank 22 for recycling.

[0044] In a specific embodiment, the present invention can accurately control the height of the loading rack 30 through the servo electric cylinder 3 25, so that the loading rack 30 can be flexibly adjusted according to the different heights of the feeding rack 2 and the unloading rack 3, ensuring that the adsorption block 33 can accurately adsorb the LED lamp beads on the feeding rack 2 and accurately place them on the substrate on the top of the unloading rack 3, avoiding loading failure or position deviation caused by height error; with the use of the micro electric cylinder 32 and the adsorption block 33, the rotation of the loading rack 30 can more accurately control the position and angle of the LED lamp beads, and the micro electric cylinder 32 can further fine-tune the height and position of the adsorption block 33, so that the LED lamp beads and the substrate are aligned.

The present invention realizes automated operation through the entire loading process, from the adsorption and transfer of the LED lamp beads to the placement on the substrate, which are all completed automatically by the equipment without human intervention. This not only improves production efficiency, but also reduces the impact of human factors on the production process, and improves production stability and consistency. Automated loading can achieve continuous and rapid production, reduce the downtime in the production process, and improve the overall utilization rate of the equipment.

[0045] The heat exchange groove 34 arranged inside the material discharging rack 3 is connected to the melt tank 22 through the circulating fan, so that the excess heat in the welding process can be recycled. During the welding process, a large amount of heat will be generated. If this heat is directly dissipated into the environment, it will not only cause energy waste, but also may affect the temperature stability of the production environment. The heat exchange groove 34 collects this excess heat and transports it to the melt tank 22, which can be used to heat the solder paste or maintain the temperature of the melt tank 22, thereby improving the utilization rate of energy and reducing the energy consumption cost in the production process.
