[0023] The following combines the drawings and specific embodiments to describe in detail a positioning jig for spot welding of a display backlight product provided by the present utility model; meanwhile, it should be noted here that in order to make the embodiments more detailed, the following embodiments are preferred embodiments, and for some well-known technologies, those skilled in the art can also adopt other alternative methods.
[0024] As Figures 1 to 4 shown, an embodiment of the present utility model provides a positioning jig for spot welding of a display backlight product, which includes a main body 1. A transport part 2 is fixedly connected to the top of the main body 1. A transmission belt 3 is rotatably connected to the inside of the transport part 2. A rotating device 4 is fixedly connected to the bottom of the inner cavity of the main body 1. A threaded column 5 is fixedly connected to the output end of the rotating device 4. A lifting seat 6 is threadedly connected to the outside of the threaded column 5. A clamping assembly 7, the clamping assembly 7 is used to fix external components, the clamping assembly 7 is connected to the lifting seat 6, the number of the clamping assemblies 7 is four, and they are distributed in two on both sides of the lifting seat 6. The clamping assembly 7 includes a rotating rod 701 rotatably connected to the outside of the lifting seat 6. The other end of the rotating rod 701 is rotatably connected to a slide block 702. A fixed plate 703 is fixedly connected to the top of the slide block 702. A clamping plate 704 is fixedly connected to the inside of the fixed plate 703. A chute 10 whose position and shape are both adapted to the slide block 702 is opened inside the transport part 2. The slide block 702 is slidably connected to the inside of the transport part 2 through the chute 10. The slide block 702 includes baffles at the top and bottom, and the baffles are in close contact with the transport part 2. The bottom of the clamping plate 704 is in close contact with the transmission belt 3. A soft pad is fixedly connected to the inside of the clamping plate 704. Side seats 8 are fixedly connected to both sides of the lifting seat 6. A limiting rod 9 is slidably connected to the inside of the side seats 8. The bottom of the limiting rod 9 is fixedly connected to the main body 1.
[0025] Place the display backlight product to be welded on the conveyor belt 3. Drive the conveyor belt 3 to rotate through the transportation department, move the backlight product to the inside of the clamping plate 704, start the rotating device 4. The rotating device 4 drives the lifting seat 6 to move downward through the threaded column 5, drives the rotating rod 701 to move, so that the slider 702 slides inward in the chute 10, drives the clamping plate 704 to approach the product through the fixing plate 703, and clamps the product.
[0026] On both sides of the lifting seat 6, there are side seats 8 and limit rods 9. These auxiliary structures further enhance the stability of the lifting seat 6, limit its lateral movement and rotation during the lifting process, and ensure that the clamping assembly 7 can always maintain the correct position and posture during operation. Since each clamping assembly 7 is driven by the same lifting seat 6, their movements are highly synchronized, avoiding problems such as uneven clamping force or offset of the fixed position caused by component asynchronization. This synchronous working method not only improves the clamping stability and reliability of the device, but also makes the entire clamping process smoother and more efficient.
[0027] As Figures 1 to 3 Shown, a top seat 11 is fixedly connected to the top of the transportation department 2. At the bottom end inside the top seat 11, a working groove 12 is opened. Inside the working groove 12, a driving structure 13 is fixedly connected. The output end of the driving structure 13 is fixedly connected with a welding head. At both ends on one side of the main body 1, movable doors 14 are hinged. The contact surface between the main body 1 and the movable doors 14 is fixedly connected with a sealing ring.
[0028] Start the driving structure 13 inside the top seat 11, drive the liftable welding head to align with the point to be welded, and the welding head starts spot welding operations. Complete the welding process according to the preset parameters. After spot welding is completed, the welding head rises back to the initial position. Reverse-start the rotating device 4, release the backlight product, transport it away through the conveyor belt 3, and transport the next backlight product to the working position.
[0029] Through the cooperation of the transportation department 2 and the clamping assembly 7, the device achieves a perfect combination of high automation and efficient operation. The clamping assemblies 7 are symmetrically distributed in pairs on both sides of the conveyor belt 3. This layout not only ensures uniform distribution of the clamping force, but also makes the clamping process more stable and reliable. After welding is completed, the clamping assembly 7 quickly releases the backlight product, and the conveyor belt 3 continues to run to transport the completed product to the next process or collection area. At the same time, a new backlight product has automatically moved to the clamping position waiting for the next clamping operation. This seamless working process not only greatly improves the working efficiency of the device, but also significantly reduces the need for manual intervention, truly achieving the goal of automated production.
[0030] Working principle provided by the present utility model: Place the display backlight product to be welded on the conveyor belt 3. Drive the conveyor belt 3 to rotate through the transportation unit, move the backlight product to the inside of the clamping plate 704. Start the rotating device 4. The rotating device 4 drives the lifting seat 6 to move downward through the threaded column 5, drives the rotating rod 701 to move, makes the slider 702 slide inward in the chute 10, drives the clamping plate 704 to approach the product through the fixing plate 703, clamps the product. The driving structure 13 in the top seat 11 is started, drives the liftable electric welding head to align with the point to be welded, and the electric welding head starts spot welding operations, completes the welding process according to the preset parameters. After spot welding is completed, the electric welding head rises back to the initial position, reversely starts the rotating device 4, releases the backlight product, transports it away through the conveyor belt 3, and transports the next backlight product to the working position.
[0031] The above rotating device 4 and driving structure 13 are publicly known prior arts in the present utility model and will not be described in detail herein.
[0032] The present utility model covers any substitutions, modifications, equivalent methods and solutions made on the essence and scope of the present utility model; in order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model, and those skilled in the art can fully understand the present utility model without the description of these details.
