Description

Technical Field

[0001] This invention belongs to the field of laser welding technology, and more specifically, relates to a welding device for manufacturing LED light strips. Background Technology

[0002] LED light strips refer to LEDs assembled on a strip-shaped FPC (flexible printed circuit board) or PCB rigid board. They are named for their strip-like shape. In the production process of LED light strips, shorter and wider LED strips are spliced ​​together using a welding device. Then, the spliced ​​LED strips are cut into longer and narrower LED strips for easier assembly and sales.

[0003] There are many existing technologies for welding equipment used in LED strip manufacturing, such as:

[0004] Chinese Patent Publication No. CN119216844A discloses an LED strip welding device, including a housing, a placement plate, and a telescopic component. The placement plate is mounted on the telescopic component, which is located on the inner bottom wall of the housing. A mounting ring is provided above the placement plate, and the mounting ring can rotate around itself. Several sliding holes are opened on the inner side of the mounting ring, and a movable cylinder is slidably connected inside the sliding holes. A piston is installed on the movable cylinder. In this LED strip welding device, when the ends of two LED strips are both below the welding head, the welding head welds the two LED strips to connect them. After the two LED strips are welded, the suction cup continues to rotate to drive the two welded LED strips to rotate and transfer the ends of subsequent LED strips to the bottom of the welding head. At this time, the welding head welds the ends of the welded LED strips to the beginnings of the unwelded LED strips to achieve the effect of continuous welding of LED strips.

[0005] Therefore, it can be seen that the above-mentioned prior art achieves continuous laser welding of light strips through the cooperation of turntable and suction cup, and achieves material loading through the arc-shaped placement plate inside the housing.

[0006] During the feeding process, the LED light strip is supported and raised / lowered by the arc-shaped placement plate inside the housing. In this way, the LED light strip stored from bottom to top gradually becomes flat (that is, the LED light strip away from the placement plate will be relatively flat, and the LED light strip close to the placement plate will be close to the arc-shaped placement plate).

[0007] Therefore, each time the curved suction cup presses downwards to attract the LED strip, it causes the LED strip above to gradually bend from a relatively flat state (e.g., Figure 10 This causes relative displacement and friction between the LED beads on the surface of the light strip and the circuit board, which can easily scratch the surface of the light strip and damage the solder joints. Summary of the Invention

[0008] This invention provides a welding device for manufacturing LED light strips, which solves the problem mentioned in the background art by enabling the light strip to complete the welding and feeding work in a flat state, namely: the surface of the light strip is easily scratched during feeding.

[0009] To solve the above-mentioned technical problems, a welding device for manufacturing LED light strips includes a bracket with a protective cover fixedly connected to it. It also includes: a slide rail with a sliding table, fixedly installed inside the protective cover, wherein an upwardly inclined laser welding gun is fixedly installed on the slide rail; a first pulley with a first belt sleeved on its outer wall, rotatably installed inside the protective cover, wherein the end of the laser welding gun faces the bottom of the first belt, and the outer wall of the first belt has multiple sets of equally spaced adsorption holes; an air extraction component is provided inside the protective cover to draw air from the adsorption holes; and a storage box with an upward opening, installed below the protective cover, wherein a top-loading component is provided at the bottom of the storage box, and mounting grooves are provided around the upper end of the storage box. Alignment components are provided in the mounting grooves to intermittently increase or decrease the area of ​​the upper port of the storage box, thereby preventing scratches on the light strips and achieving automatic alignment.

[0010] The suction component includes multiple elastic telescopic airbags fixedly installed on the inner wall of the first belt. Each elastic telescopic airbag is connected to multiple adsorption holes. The movable end of each elastic telescopic airbag is fixedly connected to a metal part. The bottom of the protective cover is fixedly connected to multiple sets of strip electromagnets located in the inner ring of the first belt. The outer wall of the first pulley is provided with an annular groove to avoid the elastic telescopic airbags, so that the light strip can be flatly adsorbed on the first belt.

[0011] The top material component includes a lifting device fixedly installed at the bottom of the storage box. The telescopic end of the lifting device is fixedly installed with a top plate located inside the storage box, which can realize the flat feeding of the light strip.

[0012] Secondly, the alignment component includes a horizontal shaft rotatably connected to the bottom of the mounting groove, an inclined plate fixedly mounted on the horizontal shaft, and a vertical plate fixedly connected to the inclined plate. The inclined plate and the vertical plate are combined to form a V-shaped plate with an opening angle greater than 120°. A torsion spring is installed between the horizontal shaft and the inner wall of the mounting groove. The outer wall of the storage box is provided with a swinging part that drives the inclined plate and the vertical plate to swing back and forth. The swinging part is used to drive the inclined plate and the vertical plate to alternately be perpendicular to the upper end face of the storage box, so that the light strip can automatically complete the alignment and positioning work during the feeding process.

[0013] Therefore, by ensuring the LED strip is flat during loading and welding, the surface of the LED strip is less likely to be scratched, the LED beads are less likely to fail, and the LED strip will be flatter after welding.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0015] 1. The present invention uses a lifting device to move the top plate and the light strip towards the first belt until the uppermost light strip is attached to the outer wall of the first belt. During this process, the light strip always remains horizontal and is only subjected to the top pressure perpendicular to its surface. As a result, the lamp beads between the light strips are less likely to rub against each other, the surface of the light strip is less likely to be scratched, and the lamp beads are less likely to fail.

[0016] 2. This invention energizes a strip electromagnet located above the light strip, generating negative pressure inside the elastic telescopic airbag. This negative pressure then attracts the light strip that is in contact with the first belt through the adsorption holes on the first belt. Throughout the adsorption process, the light strip remains basically flat, effectively preventing bending after welding and improving the quality of the light strip.

[0017] 3. In this invention, the support drives the roller to move up and down. When the roller moves upward, the vertical plate gradually moves from an inclined state to a vertical state, and the inclined plate gradually moves from a vertical state to an inclined state. As a result, the vertical plate gradually moves to a vertical state, and the uppermost light strip gradually aligns with each other, so that the light strip can be more accurately adsorbed onto the outer wall of the first belt, thereby ensuring the welding quality between the light strips.

[0018] 4. In this invention, as the roller moves downward, the vertical plate gradually tilts, while the inclined plate gradually becomes vertical. The area enclosed by the four sets of vertical inclined plates is larger than the shape and area of ​​the light strip, and is basically the same as the opening area of ​​the storage box. This makes it easier for workers to place the light strip in the storage box with a larger opening. Furthermore, when the top plate moves the light strip up and down in the storage box, the edges of the light strip are less likely to scrape against the inner wall of the storage box, ensuring the integrity of the light strip and thus ensuring the quality of subsequent light strip welding.

[0019] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] Example 1: Refer to Figures 1-5A welding device for manufacturing LED light strips includes a bracket 1 for supporting the entire device, with a protective cover 2 fixedly connected to the bracket 1. It also includes a slide rail 30 with a sliding table 32, fixedly installed inside the protective cover 2. The sliding table 32 can slide linearly on the slide rail 30. An upwardly inclined laser welding gun 31 is fixedly installed on the sliding table 32, and the laser welding gun 31 is used to weld two light strips to be connected. The device also includes a first pulley 3 with a first belt 4 sleeved on its outer wall, rotatably installed inside the protective cover 2. To ensure transmission accuracy, the first belt 4 and the first pulley 3 can also be replaced by a synchronous belt and a pulley with the same belt. A main motor 5 for driving the first pulley 3 to rotate is installed on the protective cover 2. The end of the laser welding gun 31 faces the bottom of the first belt 4. The outer wall of the first belt 4 has multiple sets of equally spaced suction holes 6 for adsorbing the light strips onto the surface of the first belt 4. The protective cover 2 has a corresponding suction hole. The device includes a suction unit that creates negative pressure inside the suction hole 6 when the light strip needs to be adsorbed. It also includes a storage bin 10 with an upward-facing opening, installed below the protective cover 2. The storage bin 10 stores stacked light strips. The gap between the upper port of the storage bin 10 and the bottom of the first belt 4 is 1.1 to 1.5 times the thickness of the light strip to prevent the light strip from rubbing against the upper port of the storage bin 10 during horizontal movement. The opening area of ​​the storage bin 10 needs to be larger than the area of ​​the light strip. The bottom of the storage bin 10 has a top-feeding component for lifting or moving the light strip upwards or downwards. The upper end of the storage bin 10 has mounting grooves 13 around its perimeter, with four sets corresponding to the four sides of the light strip. The mounting grooves 13 contain alignment components that intermittently increase or decrease the area of ​​the upper port of the storage bin 10. A controller for controlling the entire device is installed on the outer wall of the protective cover 2.

[0034] Specifically, during use, the stacked LED strips are placed on the top plate 12 inside the storage box 10, and then the LED strips are moved towards the first belt 4 by the top material component until the top LED strip is attached to the outer wall of the first belt 4. During this process, the LED strips remain horizontal and are only subjected to top pressure perpendicular to their surface. As a result, the LED beads between the LED strips are less likely to rub against each other, the LED strip surface is less likely to be scratched, and the LED beads are less likely to fail. Then, the suction component is used to suction the LED strips attached to the first belt 4 through the suction hole 6 located above the LED strips. During the entire suction process, the LED strips remain basically flat, effectively reducing the impact of bent LED strips on subsequent welding work and making the welded LED strips flatter.

[0035] Then, the light strip in the storage box 10 is moved downwards again, away from the first belt 4. Then, the main motor 5 and the first pulley 3 drive the first belt 4 to transport the attracted light strip. When the welding point of the two light strips is above the laser welding gun 31, the first belt 4 is stopped. Then, the laser welding gun 31 and the slide rail 30 are started. The slide table 32 on the slide rail 30 can drive the laser welding gun 31 to move horizontally and complete the welding work between the two light strips. During the entire welding process, the two adjacent light strips are always in a basically horizontal state, which effectively avoids the phenomenon of bending after the light strip is welded and improves the quality of the light strip.

[0036] Reference Figure 7 The aforementioned top material component includes a lifting device 11 fixedly installed at the bottom of the storage box 10. The lifting device 11 can be an electric telescopic rod, mainly controlled by a controller. The telescopic end of the lifting device 11 is fixedly installed with a top plate 12 located inside the storage box 10. When the light strip and top plate 12 inside the storage box 10 need to move up and down, the lifting device 11 can drive the top plate 12 to move up or down.

[0037] Reference Figure 2 , Figure 7 as well as Figure 8 A crossbeam 23 is fixedly connected to the support 1, and a slide block 24 is slidably installed on the crossbeam 23. The storage box 10 is fixedly connected to the slide block 24. A handle 25 is fixedly installed on the outer wall of the storage box 10. A U-shaped groove 33 symmetrically arranged at the front and back is opened at the upper end of the storage box 10.

[0038] Therefore, when it is necessary to place the light strips into the storage box 10, the storage box 10 is pulled by the handle 25, and the storage box 10 will slide on the cross frame 23 via the slide block 24. Thus, the upper opening of the storage box 10 will move away from the first belt 4, which makes it convenient for workers to place the stacked light strips into the storage box 10. The design of the U-shaped groove 33 makes the workers' material feeding operation more convenient.

[0039] Reference Figure 5 The outer wall of the first belt 4 is fixedly connected with heat-resistant strips 34 arranged at equal intervals. When the first belt 4 stops conveying and starts welding, the output end of the laser welding gun 31 faces the heat-resistant strips 34. The heat-resistant strips 34 can be made of strip-shaped stainless steel sheets. Each set of adsorption holes 6 has two rows of adsorption holes 6, and the heat-resistant strips 34 are located between the two rows of adsorption holes 6.

[0040] Therefore, during the welding process, the heat generated by the laser welding gun 31 can be applied to the heat-resistant strip 34 instead of directly to the first belt 4, thus protecting the surface of the first belt 4.

[0041] Example 2: Refer to Figure 5 and Figure 6A welding device for manufacturing LED light strips is basically the same as that in Example 1, but with a further improvement:

[0042] The aforementioned air extraction component includes multiple elastic telescopic airbags 7 fixedly installed on the inner wall of the first belt 4. The multiple elastic telescopic airbags 7 are respectively connected to multiple adsorption holes 6. The movable end of each elastic telescopic airbag 7 is fixedly connected to a metal part 8. The bottom of the protective cover 2 is fixedly connected to multiple sets of bar electromagnets 9 located in the inner ring of the first belt 4. The metal part 8 can be attracted by the bar electromagnets 9. The specific material can be stainless steel. The outer wall of the first pulley 3 is provided with an annular groove 35 to avoid the elastic telescopic airbags 7.

[0043] Specifically, by energizing the bar electromagnet 9 located above the light strip, the bar electromagnet 9 attracts the metal part 8, which in turn stretches the elastic telescopic airbag 7. The elastic telescopic airbag 7 generates a negative pressure, which is then attracted to the light strip that is in contact with the first belt 4 through the adsorption hole 6 on the first belt 4. Throughout the adsorption process, the light strip remains basically flat. After the light strip is welded, the bar electromagnet 9 above the welded light strip is de-energized, and the bar electromagnet 9 no longer attracts the metal part 8. The elastic telescopic airbag 7 elastically resets, and a positive pressure is generated inside the elastic telescopic airbag 7. The adsorption hole 6 no longer attracts the light strip.

[0044] Example 3: Reference Figures 7-9 A welding device for manufacturing LED light strips is basically the same as that in Example 2, but with a further improvement:

[0045] The aforementioned alignment component includes a horizontal shaft 14 rotatably connected to the bottom of the mounting groove 13. An inclined plate 16 is fixedly mounted on the horizontal shaft 14, and a vertical plate 15 is fixedly connected to the inclined plate 16. The inclined plate 16 and the vertical plate 15 are combined to form a V-shaped plate with an opening angle greater than 120°. A torsion spring is installed between the horizontal shaft 14 and the inner wall of the mounting groove 13. The torsion spring is used to keep the inclined plate 16 vertical when it is not under force, while the vertical plate 15 will remain tilted. The outer wall of the storage box 10 is provided with a swinging part that drives the inclined plate 16 and the vertical plate 15 to swing back and forth. The swinging part is used to drive the inclined plate 16 and the vertical plate 15 to alternately be perpendicular to the upper end face of the storage box 10.

[0046] The swinging part includes an auxiliary motor 36 fixedly installed at the bottom of the storage box 10. A turntable 20 is fixedly installed at the output end of the auxiliary motor 36. A connecting rod 21 is rotatably installed at the shaft end of the turntable 20. A lifting frame 22 is longitudinally slidably installed on the outer wall of the storage box 10. The other end of the connecting rod 21 is rotatably connected to the lifting frame 22. A roller 19 is rotatably installed on the top of the lifting frame 22 through a support 18. A protrusion 17 that cooperates with the roller 19 is fixedly connected to the outer wall of the vertical plate 15. When the lifting frame 22 moves upward, the roller 19 will press against the protrusion 17, and the vertical plate 15 will gradually swing to a vertical state, that is, a state perpendicular to the upper end of the storage box 10.

[0047] Specifically, during the continuous conveying of the light strip by the first belt 4, the auxiliary motor 36 is started. The auxiliary motor 36 drives the turntable 20 to rotate. The turntable 20 drives the lifting frame 22 to move up and down through the connecting rod 21 using the principle of a crank and slider. The lifting frame 22 drives the roller 19 to move up and down through the support 18. When the roller 19 moves upward, it presses against the protrusion 17. The protrusion 17 drives the vertical plate 15 and the inclined plate 16 to swing. The vertical plate 15 gradually moves from an inclined state to a vertical state, and the inclined plate 16 gradually moves from a vertical state to an inclined state. At this time, the area enclosed by the four sets of vertical plates 15 around the storage box 10 will just match the shape of the light strip. Thus, the gradually vertical vertical plates 15 will gradually align the uppermost light strip to a mutually aligned state, so that the light strip can be more accurately adsorbed onto the outer wall of the first belt 4, thereby ensuring the welding quality between the light strips.

[0048] To ensure more accurate positioning of the light strip, the vertical plate 15 must be kept vertical before the light strip is lifted upwards; and before the stacked light strips are placed into the storage box 10, the vertical plate 15 must be tilted to ensure that the upper opening of the storage box 10 is at its maximum, which facilitates the loading work of the workers.

[0049] Example 4: Reference Figures 2-4 A welding device for manufacturing LED light strips is basically the same as that in Example 3, but with a further improvement:

[0050] The protective cover 2 has a discharge trough at the bottom of its side wall. A second pulley 26 is rotatably mounted on the bottom inner wall of the protective cover 2. A second belt 27 is fitted on the outer wall of the second pulley 26. A feeding gap is provided between the first belt 4 and the second belt 27. The output end of the second belt 27 is close to the discharge trough. A downwardly inclined guide plate 29 is fixedly connected inside the discharge trough. The laser welding gun 31 is located between the second belt 27 and the storage box 10. One of the second pulleys 26 and one of the first pulleys 3 are connected by two meshing transmission gears 28. The first belt 4 and the second belt 27 have the same conveying speed.

[0051] Specifically, during the LED strip conveying process, the LED strip gradually enters the gap between the first belt 4 and the second belt 27. After the LED strip welding is completed and the suction hole 6 no longer suctions the LED strip, the LED strip falling downwards will fall onto the second belt 27. When the first pulley 3 rotates, it will drive the second pulley 26 to rotate through two meshing transmission gears 28. The second belt 27 will then convey the welded LED strip towards the discharge chute, thereby realizing the guiding and discharge of the LED strip.

[0052] In use, the stacked LED strips are placed on the top plate 12 inside the storage box 10. Then, the lifting device 11 moves the top plate 12 and the LED strips toward the first belt 4 until the uppermost LED strip is attached to the outer wall of the first belt 4. During this process, the LED strips remain horizontal and are only subjected to top pressure perpendicular to their surface. As a result, the LED beads between the LED strips are less likely to rub against each other, the LED strip surface is less likely to be scratched, and the LED beads are less likely to fail. Then, the bar electromagnet 9 above the LED strip is energized, which attracts the metal part 8. The metal part 8 stretches the elastic telescopic airbag 7, which generates negative pressure inside. The airbag 7 then attracts the LED strip attached to the first belt 4 through the adsorption holes 6 on the first belt 4. During the entire adsorption process, the LED strip remains basically flat, effectively reducing the impact of bent LED strips on subsequent welding work and making the welded LED strip flatter.

[0053] Then, the lifting device 11 moves the light strip in the storage box 10 downwards away from the first belt 4. Next, the main motor 5 and the first pulley 3 drive the first belt 4 to transport the attracted light strip. Before welding is completed, the bar electromagnet 9 above the light strip needs to be kept energized. Then, in the same way as above, multiple light strips are attracted at equal intervals below the first belt 4. When the welding point of two light strips is above the laser welding gun 31, the first belt 4 stops transporting. Then, the laser welding gun 31 and the slide rail 30 are started. The slide table 32 on the slide rail 30 can drive the laser welding gun 31 to move horizontally and complete the welding work between the two light strips. During the entire welding process, the two adjacent light strips are always in a basically horizontal state, which effectively avoids the phenomenon of bending after the light strip is welded and improves the quality of the light strip. When the light strip is welded, the bar electromagnet 9 above the welded light strip is de-energized. The bar electromagnet 9 no longer attracts the metal part 8, and the elastic telescopic airbag 7 will elastically reset. Positive pressure will be generated inside the elastic telescopic airbag 7, and the adsorption hole 6 will no longer attract the light strip.

[0054] During the continuous conveying of the light strip by the first belt 4, the auxiliary motor 36 is started. The auxiliary motor 36 drives the turntable 20 to rotate. The turntable 20 drives the lifting frame 22 to move up and down through the connecting rod 21 using the principle of a crank and slider. The lifting frame 22 drives the roller 19 to move up and down through the support 18. When the roller 19 moves upward, it presses against the protrusion 17. The protrusion 17 drives the vertical plate 15 and the inclined plate 16 to swing. The vertical plate 15 gradually moves from an inclined state to a vertical state, and the inclined plate 16 gradually moves from a vertical state to an inclined state. At this time, the area enclosed by the four sets of vertical plates 15 around the storage box 10 will just match the shape of the light strip. Thus, the gradually vertical vertical plate 15 will gradually align the uppermost light strip to a mutually aligned state, so that the light strip can be more accurately adsorbed onto the outer wall of the first belt 4 to ensure the welding quality between the light strips.

[0055] When the roller 19 moves downward, the protrusion 17 is no longer pressed by the roller 19. The torsion spring will cause the vertical plate 15 and the inclined plate 16 to swing back to their original positions. That is, the vertical plate 15 will gradually tilt, and the inclined plate 16 will gradually become vertical. The area enclosed by the four sets of vertical inclined plates 16 will be larger than the shape and area of ​​the light strip, and basically the same as the opening area of ​​the storage box 10. This makes it easier for the staff to place the light strip in the storage box 10 with a larger opening. When the top plate 12 drives the light strip to slide up and down in the storage box 10, the light strip is not easy to scrape against the inner wall of the storage box 10, ensuring the integrity of the light strip and thus ensuring the quality of subsequent light strip welding.
