Description

Technical Field

[0001] This invention relates to a welding apparatus, and more particularly to a continuous welding apparatus for a light source substrate, belonging to the field of light source substrate welding technology. Background Technology

[0002] In the production of light source substrates, such as LED light strips and COB light source modules, welding is a key process that determines product yield and reliability. As light source products develop towards high density and miniaturization, the number of solder joints on the substrate has surged, which places higher demands on the cleanliness and temperature consistency of the substrate surface before welding. However, traditional light source substrate welding production lines generally adopt a segmented layout, that is, cleaning, drying, welding and other processes are completed by independent equipment, and substrates need to be transferred between processes by manual or robotic arms.

[0003] This segmented production model has many inherent defects. First, the substrate is easily contaminated with dust, oil, or fingerprints during the transfer between processes, leading to defects such as poor soldering and incomplete solder wetting during welding, which directly affects the product yield. Second, each process operates independently, making it difficult to precisely match the cycle time. Lag in a certain link often causes the entire line to wait or stop, reducing the efficiency of continuous production. In addition, the cleaning fluid is usually used in a single-use or open circulation manner, which consumes a lot of fluid and is costly. Furthermore, the particulate matter in the cleaning fluid can easily cause secondary contamination of the substrate. The drying process mostly uses a single heating method, which has problems such as uneven drying and low thermal efficiency.

[0004] Therefore, it is urgent to improve the continuous welding equipment for light source substrates to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a continuous welding device for light source substrates. This device organically combines an inclined welding conveyor, multi-process integrated material feeding, cleaning, drying, double welding, and a closed-loop cleaning system to form a highly efficient continuous welding production line. The inclined design achieves a balance between gravity-assisted positioning and anti-slip, while also promoting the smooth flow of cleaning liquid and hot air along the substrate surface, reducing liquid residue accumulation, improving cleaning and drying efficiency, and seamless connection between processes to avoid secondary contamination and achieve precise cycle matching, ensuring continuous production without stopping.

The submersible pump is disposed inside the recovery chamber, which is filled with a semi-aqueous cleaning solution. The water storage plate is disposed on the top of the cleaning chamber and is provided with multiple water spray heads. The filter partition has a filter groove, and a filter screen is installed inside the filter groove.

The drying and heating mechanism includes a heating block and a heat preservation block. The heating block is positioned above the welding conveyor plate, and the heat preservation block is positioned below the welding conveyor plate.

[0011] Preferably, the heating block has a heating chamber inside, and the heating chamber is provided with multiple heating strips. The heating strips do not contact the upper side of the welding conveyor plate and are used to radiate heat to the welding conveyor plate.

[0012] Preferably, a fan is fixedly installed inside the heating chamber above the heating strip, and a dustproof grille is fixedly installed on the upper surface of the heating chamber.

[0013] Preferably, the welding conveyor is provided with multiple substrate placement compartments, which correspond to the feeding area, the cleaning area, the drying and heating area, the welding area I, and the welding area II, respectively. A clamping mechanism is fixedly provided inside each substrate placement compartment for clamping the light source substrate.

[0014] Preferably, the clamping mechanism includes a movable clamping member and a fixed clamping member. The fixed clamping member has a slot and is fixedly disposed inside the substrate placement compartment. The slot is used to engage the edge of the light source substrate.

[0016] This invention has at least the following beneficial effects: 1. This device organically combines an inclined welding conveyor, multi-process integrated batching, cleaning, drying, double welding and closed-loop cleaning system to form a highly efficient continuous welding production line. The inclined design achieves a balance between gravity-assisted positioning and anti-slip, while also causing the cleaning liquid and hot air to flow smoothly along the surface of the substrate, reducing liquid residue and improving cleaning and drying efficiency. With seamless connection between processes, it avoids secondary pollution and achieves precise cycle matching, ensuring continuous production without stopping.

[0017] 2.

The overall structure is compact and the operation is stable, with comprehensive advantages of high efficiency, high yield, low energy consumption and easy maintenance.

[0018] 3. The drying and heating mechanism is not only responsible for drying, but also preheats the welding conveyor and the light source substrate, so that the light source substrate is close to the temperature required for welding before entering welding zone I. This reduces the waiting time for heating in welding zone I and welding zone II, avoids thermal stress cracks caused by temperature difference impact on the light source substrate, and shortens the welding heating cycle, so that the welding speed is synchronized with the production line cycle and the continuous welding efficiency is improved.

[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] like Figures 1-10 As shown, the continuous welding device for light source substrates provided in this embodiment includes a welding conveyor 1 that is tilted and a driving mechanism 2 for driving the welding conveyor 1. The welding conveyor 1 is tilted at an angle of 10°-20°, which achieves a balance between gravity assistance and anti-slip of the light source substrate. If the angle is too small, the gravity assistance effect will not be obvious, and if the angle is too large, the light source substrate will easily slip or be subjected to uneven force during clamping. It is suitable for the conveying of most flat light source substrates. The inclined design allows the cleaning solution to flow away quickly under gravity after spraying, preventing liquid film residue from diluting subsequent cleaning solutions and improving cleaning efficiency. The inclined surface, combined with hot air blowing from top to bottom, allows the hot airflow to sweep across the surface of the light source substrate, accelerating moisture evaporation, reducing heat accumulation dead zones, shortening single-station processing time, and increasing overall line speed. During rotation, gravity can be used to assist in positioning the light source substrate in the clamping mechanism 5. At the same time, it facilitates the natural flow of cleaning solution and drying hot air under gravity, reducing liquid accumulation and residue. The welding conveyor 1 is equipped with a feeding area 101, a cleaning area 102, a drying and heating area 103, a welding area I 104, and a welding area II 105. Laser welding heads or hot-press welding heads can be correspondingly installed in welding areas I 104 and welding areas II 105, integrating feeding, cleaning, drying, and two welding operations onto the same turntable. The assembly line operation reduces the transfer links of the light source substrate between different processes, greatly improving production efficiency. The welding zone I 104 and welding zone II 105 are set up to adapt to the process requirements of secondary welding or welding with different parameters, enhancing the process compatibility of the device. The cleaning zone 102 is equipped with a cleaning box 3, which is used to clean the light source substrate. The drying and heating zone 103 is equipped with a drying and heating mechanism 4, which is used to dry and heat the light source substrate. After the light source substrate is cleaned in the cleaning zone 102, it is directly transferred to the adjacent drying and heating zone 103 with the welding conveyor 1. There is no exposed transfer link in between, avoiding the secondary contamination of the substrate with dust or fingerprints during the transfer process in the traditional "clean first, then transfer, then dry" mode, ensuring that the surface is absolutely clean before entering the welding zone, and improving the welding yield from the source. The substrate placement chamber 106 sequentially passes through the cleaning zone 102, the drying and heating zone 103, the welding zone I 104, and the welding zone II 105. The processing time of each station can be uniformly controlled by adjusting the rotation speed of the welding conveyor 1. The cleaning and drying speeds are precisely matched with the subsequent welding cycle, and the entire line will not be interrupted due to a delay in any link, thus achieving true "non-stop continuous welding" and greatly improving the output per unit time. The cleaning tank 3 has a cleaning chamber 301 and a recovery chamber 302 formed inside by a filter partition 303. This prevents dirt from repeatedly contacting the light source substrate during the cleaning process and ensures the cleanliness of the cleaning solution. The cleaning chamber 301 has a conveyor guide support groove 3011 corresponding to the welding conveyor 1. The conveyor guide support groove 3011 serves both as a transmission support and as a limiting guide for the rotation trajectory of the welding conveyor 1, simplifying the structure and improving operational stability. The welding conveyor 1 is rotatably mounted inside the conveyor guide support groove 3011, which supports and guides the welding conveyor 1. The recovery chamber 302 has a cleaning mechanism 6 inside. The cleaning mechanism 6 includes... The system includes a submersible pump 601 and a water storage plate 602 connected by a connecting pipe 604. The submersible pump 601 is located inside the recovery chamber 302, which is filled with a semi-aqueous cleaning solution. Compared with pure water or organic solvents, the semi-aqueous cleaning solution has the characteristics of strong cleaning ability, non-flammability, and environmental friendliness, making it suitable for the cleaning needs of precision electronic components. The water storage plate 602 is located on the top of the cleaning chamber 301 and is equipped with multiple water spray heads 603. With the water storage plate 602 on the top of the cleaning chamber 301 and the water spray heads 603 spraying downwards, combined with the welding conveyor plate 1, the cleaning solution washes the surface of the light source substrate from top to bottom, effectively removing particulate matter and oil stains. The liquid then flows downwards to the recovery chamber 302, ensuring smooth circulation. The filter baffle 303 has a filter tank 3031, and a filter screen 3032 is installed inside the filter tank 3031. The cleaning chamber 301 is connected to the inside of the recovery chamber 302 through the filter screen 3032. The cleaning liquid is filtered by the filter screen 3032 and then flows back to the recovery chamber 302 for the submersible pump 601 to extract and use again, realizing the closed-loop circulation of the cleaning liquid, which greatly saves the consumption of cleaning liquid and reduces production costs. The filter screen 3032 is installed in the filter tank 3031, which is easy to disassemble, clean or replace, and ensures the filtration effect for long-term use. This device organically combines an inclined welding conveyor plate 1, multi-process integrated material feeding, cleaning, drying, double welding and closed-loop cleaning system to form an efficient continuous welding production line. The inclined design achieves a balance between gravity-assisted positioning and anti-slip, while also causing the cleaning liquid and hot air to flow smoothly along the surface of the substrate, reducing liquid residue and improving cleaning and drying efficiency. With seamless connection between processes, it avoids secondary pollution and achieves precise cycle matching, ensuring continuous production without stopping. The cleaning tank 3 adopts a double-chamber isolation for cleaning and return and a closed-loop circulation of filter screen 3032, which greatly reduces consumption while ensuring the cleanliness of the cleaning solution. The design of welding zone I 104 and welding zone II 105 enhances process compatibility. The overall structure is compact and the operation is stable, with comprehensive advantages of high efficiency, high yield, low energy consumption and easy maintenance.

[0023] Furthermore, such as Figure 3 and Figure 6 As shown, a drive sleeve 107 is fixedly installed in the middle of the welding conveyor 1. The drive mechanism 2 includes a base 202 and a geared drive motor 201. The geared drive motor 201 can provide a large torque to meet the needs of the welding conveyor 1 to rotate under load. At the same time, it is easy to accurately control the speed and match the process time of each process. The geared drive motor 201 is fixedly installed at the upper end of the base 202. The drive output shaft 2011 of the geared drive motor 201 is rotatably installed inside the drive sleeve 107. The drive output shaft 2011 directly cooperates with the drive sleeve 107 in the center of the welding conveyor 1. The drive torque is transmitted evenly, ensuring that the welding conveyor 1 rotates smoothly and avoiding vibration caused by uneven load. The drive sleeve 107 is provided with a drive groove 1071, and the upper end of the drive output shaft 2011 is provided with a drive block 2012. The drive block 2012 is located inside the drive groove 1071. The sliding fit between the drive block 2012 and the drive groove 1071 can transmit circumferential rotational power and allow axial relative sliding, which can effectively compensate for axial displacement caused by turntable tilting or thermal expansion and contraction, and prevent jamming.

[0024] Furthermore, such as Figure 1 and Figure 8 As shown, the drying and heating mechanism 4 is fixedly mounted on the cleaning tank 3 via an L-shaped mounting plate 7, connecting the drying and heating mechanism 4 and the cleaning tank 3 as a whole, reducing the equipment footprint and improving structural compactness. The drying and heating mechanism 4 includes a heating block 401 and a heat preservation block 402. The heating block 401 is positioned above the welding conveyor plate 1, radiating heat from above. The heat preservation block 402 is positioned below to reduce heat loss, forming a three-dimensional heat preservation environment, ensuring that the welding conveyor plate 1 and the light source substrate are heated evenly, effectively shortening the drying time and improving drying efficiency. The heat preservation block 402 is positioned below the welding conveyor plate 1, reducing heat conduction downwards, lowering energy consumption, and protecting other components below from heat. Moreover, such as Figure 8As shown, a heating chamber 4011 is provided inside the heating block 401. Multiple heating strips 403 are provided inside the heating chamber 4011. The multiple heating strips 403 can cover the width direction of the welding conveyor 1, ensuring that all light source substrates passing through the drying heating zone 103 can be effectively heated. The heating strips 403 do not contact the upper side of the welding conveyor 1 and are used to radiate heat to the welding conveyor 1. The heating strips 403 do not directly contact the welding conveyor 1 to avoid friction and wear. At the same time, the radiant heating method provides uniform heat transfer and will not produce local overheating, protecting the light source substrate from heat damage. In addition, such as Figure 8 As shown, a fan 404 is fixedly installed inside the heating chamber 4011 and above the heating strip 403. The fan 404 blows the heat generated by the heating strip 403 downward to the surface of the light source substrate in the form of hot air, forming convection heat transfer, which significantly improves the drying speed and shortens the production cycle. A dustproof grille 405 is fixedly installed on the upper end face of the heating chamber 4011. The dustproof grille 405 on the upper end face filters large particles of dust from the outside while ensuring air intake, preventing contaminants from entering the heating chamber 4011 and affecting the cleanliness of the light source substrate, thus ensuring the welding quality. Therefore, the drying and heating mechanism 4 is not only responsible for drying, but also preheats the welding conveyor 1 and the light source substrate, so that the light source substrate is close to the temperature required for welding before entering the welding zone I 104, reducing the waiting time for the heating of the welding zone I 104 and the welding zone II 105, avoiding thermal stress cracks caused by temperature difference impact on the light source substrate, and shortening the welding heating cycle, so that the welding speed is synchronized with the production line cycle and the continuous welding efficiency is improved.

[0025] Furthermore, such as Figure 1 , Figure 7 as well as Figure 10 As shown, the welding conveyor 1 has multiple substrate placement chambers 106. The multiple substrate placement chambers 106 correspond to the feeding area 101, the cleaning area 102, the drying and heating area 103, the welding area I 104, and the welding area II 105, respectively. Each substrate placement chamber 106 passes through all processes in sequence as the welding conveyor 1 rotates, ensuring that the process sequence and duration of each light source substrate are consistent, thus ensuring product consistency. A clamping mechanism 5 is fixedly installed inside the substrate placement chamber 106. The clamping mechanism 5 is used to clamp the light source substrate. The clamping mechanism 5 is fixed inside the substrate placement chamber 106 and always firmly clamps the light source substrate during the tilting and rotation of the welding conveyor 1, preventing the light source substrate from shifting or falling off. The clamping mechanism 5 includes a movable clamping member 501 and a fixed clamping member 502. The fixed clamping member 502 has a slot 5021. The fixed clamping member 502 serves as the load-bearing side, bearing most of the weight of the light source substrate. It has good structural rigidity and is not easily deformed during long-term use. The fixed clamping member 502 is fixedly installed inside the substrate placement chamber 106, and the slot 5021 is used to engage the edge of the light source substrate. The slot 5021 cooperates with the edge of the light source substrate to serve as a positioning reference, ensuring that the position of the light source substrate is consistent each time it is placed, which is beneficial to the precise alignment of subsequent welding processes. The movable clamping component 501 includes a fixed sleeve 5011 and a brake shaft 5012 that are slidably connected. One end of the brake shaft 5012 is connected to a limit block 5013. The limit block 5013 is slidably disposed inside the fixed sleeve 5011. The limit block 5013 slides within the fixed sleeve 5011, effectively limiting the travel range of the brake shaft 5012, preventing the spring 5015 from being over-compressed or the shaft from coming out, and improving the reliability of the mechanism. The other end of the brake shaft 5012 is connected to a rubber head 5016. The rubber head 5016 abuts against the light source substrate. The rubber head 5016 makes elastic contact with the light source substrate, which neither damages the substrate surface nor provides enough friction to prevent the light source substrate from sliding. It is especially suitable for the operation of the tilting turntable. A spring 5015 is provided between the rubber head 5016 and the fixed sleeve 5011. The spring 5015 is sleeved on the brake shaft 5012. The spring 5015 pushes the brake shaft 5012, so that the rubber head 5016 always presses the edge of the light source substrate. It can automatically adapt to the slight difference in the thickness of the light source substrate and avoid damage to the light source substrate caused by rigid clamping.

[0026] Finally, as Figure 4 and Figure 5 As shown, a support block 3033 is fixedly installed inside the filter tank 3031, and the filter screen 3032 is fixedly installed on the support block 3033. The support block 3033 provides a flat and reliable mounting surface for the filter screen 3032, ensuring that the filter screen 3032 does not deform or shift under the impact of liquid flow. A cleaning door 3012 is rotatably installed on one side of the cleaning chamber 301. The cleaning door 3012 can be opened, which facilitates the operator to regularly clean the inside of the cleaning chamber 301, inspect the water spray head 603, and replace the filter screen 3032, reducing the difficulty of maintenance. A glass window 3021 is installed on one side of the recovery chamber 302. The glass window 3021 allows the operator to directly observe the liquid level and cleanliness of the cleaning fluid in the recovery chamber 302 without opening the equipment, and promptly determine whether the cleaning fluid needs to be replenished or replaced, thereby improving the intelligent management level of the equipment.

[0027] like Figures 1-10 As shown, the principle of the continuous welding apparatus for the light source substrate provided in this embodiment is as follows: Using the inclined welding conveyor 1 as the core carrier, the five processes of material preparation, cleaning, drying, welding zone I and zone II are integrated into different angle areas of the same welding conveyor 1. The drive mechanism 2 drives the welding conveyor 1 to rotate at a constant speed through the reduction drive motor 201. The light source substrate placed in the substrate placement chamber 106 passes through each process area in sequence with the tray, realizing continuous cycle operation of loading, cleaning, drying, primary welding, secondary welding and unloading. Throughout the process, the light source substrate is always fixed in the clamping mechanism 5 and does not need to be transferred in the middle, forming a closed production line. The cleaning tank 3 is divided into a cleaning chamber 301 and a recovery chamber 302 by a filter baffle 303. The water storage plate 602 at the top of the cleaning chamber 301 sprays semi-aqueous cleaning liquid downwards through multiple water nozzles 603 to rinse the surface of the substrate. The cleaned liquid, carrying dirt, flows into the bottom of the cleaning chamber 301. After being filtered by the filter screen 3032 on the filter baffle 303, it enters the recovery chamber 302. The clean cleaning liquid stored in the recovery chamber 302 is drawn by the submersible pump 601 and pumped to the water storage plate 602 through the connecting pipe 604. It is then sprayed out again from the water nozzles 603, forming a closed loop of spraying, rinsing, filtering, back-drawing, and re-spraying. This ensures the cleaning effect while enabling the reuse of the cleaning liquid.
