Description

Technical Field

[0001] This utility model belongs to the field of LED light strip production technology, specifically a welding equipment for LED light strip processing. Background Technology

[0002] In LED strip manufacturing, welding is a critical process, mainly involving two scenarios: welding two strip sections together and welding connecting wires to the strip. The former achieves the electrical and physical connection between two strip sections through welding, meeting the needs of different lengths; the latter uses connecting wires to connect the strip to a power supply or other control equipment, thereby enabling power supply and control of the strip. To ensure welding efficiency and quality, the welding equipment must be equipped with a positioning mechanism to fix the position of the strip and connecting wires.

[0003] However, due to the significant differences in the cross-sectional shape and size of the light strip and the connecting wire, existing positioning mechanisms are difficult to adapt to both welding scenarios simultaneously. Furthermore, different specifications of light strips have varying widths, requiring flexible adjustment of the connecting wire's positioning and welding position according to the light strip width. However, existing welding equipment suffers from inconvenient adjustment of the connecting wire's positioning position, resulting in limited positioning functionality. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a welding equipment for LED light strip processing, so as to at least partially solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: A welding device for LED light strip processing is proposed, comprising a worktable, a positioning roller, a positioning block, and a mounting frame. The positioning roller and mounting frame are configured to be lifted and positioned above the worktable. The positioning roller is used to fix one set of light strips. The positioning block is rotatably mounted on the mounting frame via a rotating shaft. A wire pressing groove is formed on one surface of the positioning block for fixing a connecting wire. The other surface of the positioning block opposite to the wire pressing groove is used to fix another set of light strips. Two sets of positioning blocks are provided, and the lateral spacing between the two sets of positioning blocks is adjustable.

[0006] Furthermore, the workbench is equipped with a spacing adjustment mechanism, which includes a first bracket, a bidirectional screw, a spacing adjustment slide, and a spacing adjustment block. The first bracket is fixedly mounted on the workbench, the bidirectional screw is rotatably mounted on the first bracket, and one end of the bidirectional screw is connected to a handwheel. The spacing adjustment slide is fixedly mounted on the first bracket, and the spacing adjustment block is connected to the bidirectional screw via a thread. The spacing adjustment block is slidably mounted on the spacing adjustment slide, and a load-bearing plate is provided on the spacing adjustment block. The first screw is connected to the load-bearing plate via a thread, and a guide groove is provided on the spacing adjustment block. The mounting bracket is connected to the first screw, and a guide protrusion is provided on the mounting bracket. The guide protrusion is engaged and slidably mounted in the guide groove.

[0007] Furthermore, one end of the rotating shaft is connected to a rotating force-applying plate, and the mounting bracket is provided with two sets of anti-rotation grooves, which are located on the same straight line. The rotating force-applying plate is provided with an anti-rotation mechanism, which is configured to slide relative to the anti-rotation groove.

[0008] Furthermore, the anti-rotation mechanism includes an anti-rotation column, a pull plate, and a force-applying spring. The anti-rotation column is slidably mounted on the rotating force-applying plate. The pull plate is fixedly connected to one end of the anti-rotation column and is located outside the rotating force-applying plate. A limiting plate is fixedly mounted on the anti-rotation column. The end of the anti-rotation column with the limiting plate is configured to slide within the anti-rotation groove. The force-applying spring is sleeved on the anti-rotation column, and both ends of the force-applying spring are respectively connected to the rotating force-applying plate and the limiting plate.

[0009] Furthermore, the longitudinal section of the pressure groove is an inverted triangular or trapezoidal structure.

[0010] Furthermore, the workbench is provided with a pressure roller adjustment mechanism, which includes a second bracket, a second screw, a slide rod, and a mounting frame. The second bracket is fixedly mounted on the workbench, the second screw is screwed onto the second bracket, the slide rod is slidably mounted on the second bracket, the mounting frame is connected to the second screw and the slide rod, and the positioning pressure roller is rotatably mounted on the mounting frame.

[0011] The beneficial effects of this utility model by adopting the above structure are as follows:

[0012] (1) By setting up a positioning block that can rotate and adjust the pressing surface, the fixed positioning requirements of connecting wires or light strips of different sizes are met at the same time; and by setting up an anti-rotation mechanism, the automatic rotation of the shaft can be avoided, which improves the stability of the positioning block for fixing the connecting wires or light strips.

[0013] (2) The spacing between the two sets of positioning blocks is adjusted by setting the spacing adjustment mechanism so that the welding position of the two sets of connecting lines can be adapted to the light strips of different widths. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0022] See Figures 1-4This embodiment provides a welding device for LED light strip processing, including a worktable 1, a positioning roller 2, a positioning block 3, and a mounting frame 4. The positioning roller 2 and the mounting frame 4 are configured to be raised and lowered above the worktable 1. The positioning roller 2 is used to fix a group of light strips. The lowered positioning roller 2 can fix a group of light strips on the worktable 1. The positioning block 3 is rotatably mounted on the mounting frame 4 via a rotating shaft 5. A wire pressing groove 6 is opened on one surface of the positioning block 3. The wire pressing groove 6 is used to fix the connecting wire. The other surface of the positioning block 3 opposite to the wire pressing groove 6 is used to fix another group of light strips. The fixing working surface of the positioning block 3 can be adjusted by rotating the positioning block 3. The lowered positioning block 3 can fix another group of light strips or connecting wires on the worktable 1. There are two sets of positioning blocks 3. The lateral distance between the two sets of positioning blocks 3 is adjustable. By adjusting the position of the two sets of positioning blocks 3, the positioning and welding of connecting wires corresponding to light strips of different widths can be achieved.

[0023] In use, a set of light strips is placed on the workbench 1, and the positioning roller 2 is controlled to descend. The positioning roller 2 presses onto the set of light strips to position them. When the other part to be welded to the same set of light strips is also a light strip, the rotating shaft 5 controls the positioning block 3 to face the worktable 1 with one surface away from the wire pressing groove 6. The other set of light strips is placed on the worktable 1, and the welding ends of the two sets of light strips are joined together. The mounting frame 4 and the positioning block 3 are lowered, and the surface of the positioning block 3 presses onto the other set of light strips to position them. The light strips can then be welded using a soldering gun. When the other part to be welded to the same set of light strips is a connecting wire, the positions of the two connecting wires are adjusted according to the width of the light strip so that the ends of the two connecting wires correspond to the two welding points of the light strip. The rotating shaft 5 controls the positioning block 3 to face the worktable 1 with one surface having the wire pressing groove 6. The spacing between the two sets of positioning blocks 3 is adjusted to adapt to the positions of the two sets of connecting wires. The mounting frame 4 and the positioning block 3 are lowered, and the positioning block 3 presses onto the connecting wires through the wire pressing groove 6 to position them. The connecting wires can then be welded using a soldering gun.

[0024] Specifically, see Figure 2 and Figure 3In this embodiment, the workbench 1 is provided with a spacing adjustment mechanism 7. The spacing adjustment mechanism 7 includes a first bracket 8, a bidirectional screw 9, a spacing adjustment slide rod 10, and a spacing adjustment block 11. The first bracket 8 is fixedly mounted on the workbench 1. The bidirectional screw 9 is rotatably mounted on the first bracket 8. One end of the bidirectional screw 9 is connected to a handwheel 12. The spacing adjustment slide rod 10 is fixedly mounted on the first bracket 8. The spacing adjustment block 11 is connected to the bidirectional screw 9 by a thread. The spacing adjustment block 11 is slidably mounted on the spacing adjustment slide rod 11. The spacing adjustment block 11 is provided with a load-bearing plate 13. The load-bearing plate 13 is connected to the first screw 14 by a thread. The spacing adjustment block 11 is provided with a guide groove 15. The mounting frame 4 is connected to the first screw 14. The mounting frame 4 is provided with a guide protrusion 16. The guide protrusion 16 is engaged and slidably mounted in the guide groove 15.

[0025] In use, rotating the handwheel 12 drives the bidirectional screw 9 to rotate. Driven by the bidirectional screw 9 and guided by the spacing adjustment slide 10, the spacing adjustment block 11 is moved. The spacing adjustment block 11 drives the mounting frame 4 and the positioning block 3 to move, adjusting the lateral spacing between the two sets of positioning blocks 3. After the adjustment is in place, rotating the first screw 14 drives the mounting frame 4 to lower the positioning block 3. The lowered positioning block 3 is used to fix the light strip or connecting wire on the workbench 1. When the first screw 14 drives the positioning block 3 to rise and fall, the guide protrusion 16 slides along the guide groove 15 to ensure the vertical rise and fall of the mounting frame 4.

[0026] Specifically, see Figure 3 and Figure 4 In this embodiment, one end of the rotating shaft 5 is connected to a rotating force plate 17. By rotating the force plate 17, the rotating shaft 5 can be rotated, thereby adjusting the pressing surface of the positioning block 3 toward the worktable 1. The mounting frame 4 is provided with two sets of anti-rotation grooves 18, which are located on the same straight line. The rotating force plate 17 is provided with an anti-rotation mechanism, which is configured to slide relative to the anti-rotation grooves 18.

[0027] Specifically, see Figure 3 In this embodiment, the anti-rotation mechanism includes an anti-rotation column 19, a pulling plate 20, and a force-applying spring 21. The anti-rotation column 19 is slidably disposed on the rotating force-applying plate 17. The pulling plate 20 is fixedly connected to one end of the anti-rotation column 19 and is located outside the rotating force-applying plate 17. A limiting plate 22 is fixedly disposed on the anti-rotation column 19. The end of the anti-rotation column 19 with the limiting plate 22 is configured to slide within the anti-rotation groove 18. The force-applying spring 21 is sleeved on the anti-rotation column 19, and the two ends of the force-applying spring 21 are respectively connected to the rotating force-applying plate 17 and the limiting plate 22.

[0028] It should be noted that in this embodiment, the anti-rotation mechanism can be set in one or two sets. In this embodiment, to further improve the stability of the anti-rotation of the rotating shaft 5, two sets of anti-rotation mechanisms are set, and the pull plates 20 of the two sets of anti-rotation mechanisms are connected (see...). Figure 3 In use, the rotating shaft 5 needs to be rotated 180°. When adjusting the working surface of the positioning block 3, force is applied outward to the pulling plate 20. The pulling plate 20 drives the anti-rotation column 19 to slide along the rotating force plate 17. One end of the anti-rotation column 19 slides out of the anti-rotation groove 18, and the force spring 21 is in a compressed state. At this time, force is applied to the rotating force plate 17 to rotate, which drives the positioning block 3 to rotate. After rotating 180°, the pressing surface of the positioning block 3 is adjusted, and the pulling plate 20 is released. Under the action of the force spring 21, the anti-rotation column 19 is re-embedded into the anti-rotation groove 18, fixing the state of the rotating shaft 5 and the positioning block 3 and preventing the rotating shaft 5 from rotating on its own.

[0029] Specifically, see Figure 2 In this embodiment, the longitudinal section of the pressure groove 6 is an inverted triangular or trapezoidal structure. The above structure setting better meets the positioning requirements of connecting wires of different diameters.

[0030] Specifically, see Figure 1 In this embodiment, the workbench 1 is provided with a pressure roller adjustment mechanism 23. The pressure roller adjustment mechanism 23 includes a second bracket 24, a second screw 25, a slide rod 26 and a mounting frame 27. The second bracket 24 is fixedly mounted on the workbench 1. The second screw 25 is screwed onto the second bracket 24. The slide rod 26 is slidably mounted on the second bracket 24. The mounting frame 27 is connected to the second screw 25 and the slide rod 26. The positioning pressure roller 2 is rotatably mounted on the mounting frame 27.

[0031] In use, rotating the second screw 25 drives the mounting frame 27 to rise and fall under the driving force of the second screw 25 and the guiding force of the slide bar 26. The mounting frame 27 drives the positioning pressure roller 2 to rise and fall. The descending positioning pressure roller 2 presses onto the light strip to complete the positioning and fixing of the light strip.
