[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0026] Reference Figures 1 to 3 The light bar transport device provided in the embodiment of the present application includes a support device (not shown) for placing multiple light bars, a rotary motor 10 disposed above the support device, a rocker arm 20 disposed on the rotary motor 10, and a transport fixture 30 disposed on the rocker arm 20. When the rotary motor 10 rotates, it drives the rocker arm 20 to move, thereby driving the transport fixture 30 to move, which is used to transfer the light bar from the support device to the fixture at the next workstation.

[0027] The handling fixture 30 includes a fixture bracket 31, a first guide rod 32 and a second guide rod 33 arranged parallel to the fixture bracket 31, a plurality of sliders 34 arranged on the first guide rod 32, a suction nozzle 35 disposed at the bottom of each slider 34, and a toggle device 36 disposed on the second guide rod 33. A connecting block 37 is provided between several adjacent sliders 34 among the plurality of sliders 34. The connecting block 37 has a connecting groove 371 parallel to the first guide rod 32. At least one of the adjacent sliders 34 is connected to the connecting block 37 via a connecting member, such as a screw (not shown), located in the connecting groove 371. The toggle device 36 is connected to the slider 34 away from the rocker arm 20. The toggle device 36 is connected to a driving device (not shown) and is driven by the driving device to move along the second guide rod 33 to adjust the spacing between the plurality of sliders 34.

[0028] To improve production efficiency, multiple light strips are generally welded simultaneously on a production line. Each light strip is composed of multiple light bars connected in series, and the spacing between adjacent light bars is different, which means that the spacing between the receiving positions for the light bars on the welding fixture is different. When the light bars are placed on the support device before being picked up, the multiple light bars are arranged horizontally and closely together. Therefore, before using the handling fixture 30 to pick up the light bars, the forward movement of the toggle device 36 (close to the rocker arm 20) is used to toggle the slider 34 so that the multiple sliders 34 are close to each other, so that each suction nozzle 35 corresponds to the position of each light bar for picking up the light bar. After picking up, the distance between the sliders 34 is widened by the reverse movement of the toggle device 36 (away from the rocker arm 20), so that the suction nozzles 35 on each slider 34 match the spacing of the receiving positions on the welding fixture, making it convenient to place the picked light bar on the welding fixture. During the movement of the sliders 34, adjacent sliders 34 are connected by connecting blocks 37, and connecting blocks 37 have connecting grooves 371 therebetween. At least one connecting member on a slider 34 is located within the connecting grooves 371. Thus, the distance between adjacent sliders 34 is shortened or lengthened by the sliding movement of the connecting member within the connecting grooves 371. The aforementioned handling structure allows for fully automated light bar pickup, significantly improving work efficiency and accuracy while saving labor costs.

[0029] Specifically, in this embodiment, the shifting device 36 includes a slide 361 mounted on the second guide rod 33, and a shifting block 362 fixed to the side wall of the slide 361. The shifting block 362 is fixedly connected to the side wall of the slider 34 away from the rocker arm 20. Figure 1As shown, the shift block 362 is fixedly connected to the rightmost slider 34. When the shift block 362, driven by the slide 361, moves toward the rocker arm 20, the shift block 362 shifts the rightmost slider 34. The connecting blocks 37 between adjacent sliders 34 act to gradually bring the multiple sliders 34 together and eventually abut against each other. When the slider 361 is moved in the opposite direction, the adjacent sliders 361 are pulled apart. In this embodiment, the driving device is a pneumatic cylinder. That is, the movement of the slider 361 along the second guide rod 33 is driven by the cylinder. The second guide rod 33 acts as a guide, ensuring the horizontal linear motion of the slider 361 and improving the stability of the structure.

[0030] Specifically, the shift block 362 is L-shaped, one end of the L-shaped shift block is fixedly connected to the side wall of the slide 361, and the other end of the L-shaped shift block is fixedly connected to the side wall of the slider 34. This structure is simple and convenient for connecting the shift block 362 with the slide 361 and the slider 34.

[0031] Reference Figure 3 In this embodiment, the connection slots 371 of the connecting blocks 37 have different lengths. Due to the different lengths of the connection slots 371 , when the sliders 34 are moved, the spacing between adjacent sliders 34 can be made different, and the spacing is proportional to the length of the connection slots 371 .

[0032] In order to prevent the connection blocks 37 from interfering with each other during movement, several connection blocks 37 are staggered in the vertical direction.

[0033] Further, two or more connecting blocks 37 are provided between two adjacent sliders 34. Like this, by two or more connecting blocks 37, the movement of slider 34 is made more stable.

[0034] In this embodiment, the light bar handling device further includes a column 40 disposed adjacent to the support device. A rotary motor 10 is disposed on top of the column 40. The output end of the rotary motor 10 passes through the column 40 and is connected to one end of a rocker arm 20. The other end of the rocker arm 20 is rotatably connected to a fixture bracket 31. Synchronous pulleys 50 are provided at each end of the rocker arm 20, and a synchronous belt 51 is provided on each of the synchronous pulleys 50. The provision of the synchronous belt structure makes the movement of the rocker arm 20 more stable, and the synchronous belt 51 ensures the repeatability of the rocker arm 20's movement, thereby improving production efficiency.

[0035] Further, refer to Figure 2 In order to make the synchronous belt 51 work better, a tensioning pulley 52 for adjusting the tightness of the synchronous belt 51 is provided on the rocker arm 20. At the same time, a strip-shaped adjustment groove 21 is vertically provided on the rocker arm 20. The rotating shaft of the tensioning pulley is fixed in 52. By moving the rotating shaft up and down in the strip-shaped adjustment groove 21, the tensioning effect of the tensioning pulley 52 on the synchronous belt 51 can be adjusted.

[0036] Reference Figure 2The fixture bracket 31 includes a rotating shaft 311 that passes through one end of the rocker arm 20, a connecting base 312 that sleeves on the rotating shaft 311, and an inverted U-shaped frame 313 located at the bottom of the connecting base 312. Two first guide rods 32 are horizontally arranged between the two side walls of the inverted U-shaped frame 313. Multiple sliders 34 are simultaneously sleeved on the two first guide rods 32. The provision of two first guide rods 32 provides guide support at both the top and bottom of the sliders 34, improving their stability during movement.

[0037] In this embodiment, two fixing blocks 314 are respectively provided at the front ends of the two side walls of the inverted U-shaped frame 313, and the second guide rod 33 is horizontally disposed between the two fixing blocks 314. The two fixing blocks 314 and the second guide rod 33 enclose the entire fixture bracket 31, giving it a frame-like structure and improving stability. Furthermore, because the two fixing blocks 314 are located at the front ends of the two side walls, the second guide rod 33 is positioned in front of the first guide rod 32, and the slide 361 on the second guide rod 33 and the slide 34 on the first guide rod 32 do not interfere with each other.

[0038] In summary, the light bar transport device provided in the embodiment of the present application has a simple structure, and can pick up and transport multiple light bars with different spacings, thereby improving production efficiency and reducing labor costs.

[0039] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
