[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-3 This utility model provides a technical solution for an automatic welding machine fixture: it includes a welding fixture plate 1 for placing a light strip 2, the light strip 2 being divided into a first light strip section and a second light strip section, i.e. Figure 1 The left side is the first LED strip section, and the right side is the second LED strip section. The automatic welding machine fixture is used to fix the first LED strip section and the second LED strip section for welding connection.
[0024] The welding fixture plate 1 is equipped with a side clamping mechanism 3 and a strong clamping mechanism 4 on both sides. There are two sets of side clamping mechanisms 3, and the two sets of side clamping mechanisms 3 are respectively movably installed at both ends of one side of the upper surface of the welding fixture plate 1. The strong clamping mechanism 4 is located in the middle of the welding fixture plate 1, and a fixing tape 14 is provided on one side of the strong clamping mechanism 4. The first light strip is fixed by the side clamping mechanism 3 and the fixing tape 14, and the second light strip is fixed by the strong clamping mechanism 4 and the side clamping mechanism 3 on the other side. Positioning and clamping mechanisms 15 for positioning and clamping the light strip are provided at both ends of one side of the welding fixture plate 1.
[0025] Please refer to Figure 2 In this embodiment, the side-pressure fixing mechanism 3 includes a movable base 5, an elbow clamp fixing plate 6, an upper elbow clamp 8, and a side-pressure fixing plate 7. The elbow clamp fixing plate 6 is fixedly installed on the movable base 5 by screws, the upper elbow clamp 8 is fixedly installed on the elbow clamp fixing plate 6, and the side-pressure fixing plate 7 is movably installed on one side of the movable base 5 by hinges. The side-pressure fixing plate 7 is located below the upper elbow clamp 8.
[0026] Specifically, the welding fixture plate 1 is provided with a slide groove 9, and the bottom of the movable base 5 is movably installed in the slide groove 9.
[0027] In this embodiment, the LED strip is initially positioned by adjusting the side clamping mechanism 3. The movable base 5 of the side clamping mechanism 3 slides within the groove 9, allowing the upper elbow clamp 8 and the side clamping plate 7 to flexibly clamp LED strips of different sizes at different positions. Simultaneously, the side clamping plate 7 is hinged and mounted on one side of the movable base 5. The upper elbow clamp 8 applies pressure to the side clamping plate 7 by pressing it, ensuring the stability of the LED strip.
[0028] Furthermore, the strong clamping mechanism 4 includes an intermediate clamping plate 10 and a lower elbow clamp 11. One end of the intermediate clamping plate 10 is movably connected to the upper side of the welding fixture plate 1 via a hinge. The lower elbow clamp 11 is located on the lower side of the welding fixture plate 1 and is fixedly mounted on the welding fixture plate 1 by screws.
[0029] It should be noted that both the upper elbow clamp 8 and the lower elbow clamp 11 are existing devices with mechanical claws and drive arms. They can adjust the angle of the drive arm by rotation, allowing the mechanical claws to clamp and release the target object. Existing elbow clamp devices come in various types and structures, but their functions are the same; therefore, they will not be described in detail in this embodiment.
[0030] In this embodiment, the second LED strip is further secured by adjusting the high-pressure fixing mechanism 4. After the intermediate fixing plate 10 is flipped over, it can apply greater pressure to the second LED strip under the action of the lower elbow clamp 11, ensuring that the second LED strip will not move during the welding process.
[0031] Please refer to Figure 2 and Figure 3 Furthermore, the length of the intermediate clamping plate 10 is equal to the width of the welding fixture plate 1. A clearance groove 12 is provided on one side of the intermediate clamping plate 10, which obliquely penetrates the top and side surfaces of the intermediate clamping plate 10. This allows the intermediate clamping plate 10 to clamp positions closer to the light strip. Due to the presence of the clearance groove 12, the intermediate clamping plate 10 is less likely to interfere with the welding gun. A rubber pad 13 is provided on the lower surface of the intermediate clamping plate 10. The rubber pad 13 increases the friction between the intermediate clamping plate 10 and the light strip while protecting the surface of the light strip from damage.
[0032] Furthermore, the upper and lower ends of the fixing tape 14 are bonded to the welding fixture plate 1, and the middle part of the fixing tape 14 is bonded to the first light strip. The fixing tape 14 is used to fix the first light strip on one side.
[0033] Please refer to Figure 2 and Figure 4In this embodiment, the positioning and clamping mechanism 15 includes a positioning plate 17 fixedly mounted on the welding fixture plate 1 and a movable pressure plate 18 elastically slidably mounted on the side of the positioning plate 17 near the light strip. The sliding direction of the movable pressure plate 18 is perpendicular to the top surface of the welding fixture plate 1. The positioning plate 17 is used to position the light strip, and the movable pressure plate 18 is used to clamp the light strip. The positioning and clamping mechanism 15 can both position the side of the light strip and form a preliminary clamping effect on the light strip. It is easy to operate, and the positioning and fixing are accurate and stable, which can improve welding efficiency.
[0034] The positioning plate 17 has detachable sliding groove plates 16 at both ends. Each sliding groove plate 16 has a groove for sliding connection with the movable pressure plate 18, allowing for overlapping sliding between the positioning plate 17 and the movable pressure plate 18. Both the positioning plate 17 and the movable pressure plate 18 have mounting grooves for installing elastic elements 19 on their adjacent sides. The elastic elements 19 are confined between the positioning plate 17 and the movable pressure plate 18, and can drive the movable pressure plate 18 to slide towards the light strip to secure it.
[0035] In addition, the movable pressure plate 18 is provided with a protruding edge strip 181 on the side near the light strip, so that the movable pressure plate 18 can be operated to slide away from the light strip, so that the side of the light strip can first contact and position with the positioning plate 17. After the operating force of the protruding edge strip 181 is released, the movable pressure plate 18 slides down under the elastic force of the elastic member 19 to press and fix the light strip.
[0036] Working principle: In use, the operator first drives the movable pressure plate 18 to slide upward by operating the convex edge strip 181. Then, the second LED strip to be welded is placed on one side of the welding fixture plate 1, and the second LED strip is pushed to slide and contact the positioning plate 17 for positioning. The convex edge strip 181 is released, allowing the movable pressure plate 18 to slide down and press the second LED strip firmly. Then, the intermediate pressing plate 10 is flipped downward to press the second LED strip tightly. Under the action of the lower elbow clamp 11, the intermediate pressing plate 10 can apply pressure to the second LED strip to ensure that the second LED strip will not move during the welding process.
[0037] Next, the outer side of the second light strip is positioned and fixed by the side clamping mechanism 3. The movable base 5 of the side clamping mechanism 3 slides in the slide groove 9, allowing the upper elbow clamp 8 and the side clamping plate 7 to flexibly clamp the first part of the light strip 2 of different sizes at different positions. At the same time, the side clamping plate 7 is hinged and mounted on one side of the movable base 5. The upper elbow clamp 8 applies pressure to the side clamping plate 7 by pressing it, ensuring the stability of the second light strip.
[0038] Then, the other protruding edge strip 181 is operated in the same way to drive the movable pressure plate 18 to slide upward. The first light strip to be welded is then placed on one side of the welding fixture plate 1, and the first light strip is pushed to slide and contact the positioning plate 17 for positioning. The protruding edge strip 181 is released so that the movable pressure plate 18 slides down to press and fix the first light strip. At the same time, it is important to ensure that one end of the first light strip is aligned with the second light strip. Then, one end of the first light strip is fixed with the fixing tape 14, and the outer side of the first light strip is pressed and fixed by another set of side pressing mechanisms 3.
[0039] Finally, the operator starts the welding machine to weld the multiple points between the first and second light strip sections one by one.
