[0041] Reference Figure 1 as well as Figure 4 The panel separation assembly includes a single-row panel separation mechanism, a pushing mechanism and a single-piece panel separation mechanism; the single-row panel separation mechanism is suitable for separating the whole panel into a single-row panel, the pushing mechanism is suitable for pushing the single-row panel to the single-piece panel separation mechanism, the single-piece panel separation mechanism is suitable for separating the single-row panel into a single panel and transporting the single panel to the mainboard conveyor; the mainboard conveyor has a plurality of welding bosses 51 arranged at intervals; the single-piece panel separation mechanism is suitable for placing the single panel on the welding bosses 51. Figure 3 as well as Figure 5The welding assembly includes a frame 61, a welding rod 62 movable in the vertical direction and a positioning fixture; the frame 61 is arranged on the base 100, and the welding rod 62 is connected to the frame 61; the positioning fixture includes a lower positioning member, an upper positioning member and a clamping positioning member; the lower positioning member includes a lower driving member 63 and a positioning boss 64, and the lower driving member 63 is suitable for driving the positioning boss 64 to move in the vertical direction; the upper positioning member includes an upper driving member 65 and an upper pressing plate 66, and the upper driving member 65 is suitable for driving the upper pressing plate 66 to move in the vertical direction; a pressing block 661 is arranged on the upper pressing plate 66, and the pressing block 661 and the positioning boss 64 are located in the same vertical direction, and the pressing block 661 and the positioning boss 64 are located between the welding boss 51 and the lamp tube transmission assembly; the clamping positioning member is suitable for clamping and positioning the single plate on the welding boss 51.

[0042] A tube pushing mechanism is also provided on one side of the lamp tube conveying assembly away from the base 100, and the tube pushing mechanism is suitable for pushing the semi-finished lamp tube toward the positioning boss 64 so that the semi-finished lamp tube abuts against the positioning boss 64 for positioning.

[0043] In the above-mentioned setting, the panel splitter assembly can split the whole panel into single panels, so as to facilitate the final welding with the soft substrate of the semi-finished lamp tube. This process does not require manual operation and has a high degree of automation. Specifically, the whole panel is firstly split into single-row panels by the single-row panel splitter mechanism, and then the single-row panels are pushed to the single-piece panel splitter mechanism by the pushing mechanism, and finally the single-piece panel splitter mechanism splits the single-row panels into single panels and transports the single panels to the mainboard conveyor. When welding, refer to Figure 10-12 , through the cooperation of the lower positioning member and the upper positioning member, the soft substrate of the semi-finished lamp tube can be pressed against the positioning boss 64 by the pressing block 661, thereby ensuring the reliability of welding between the main board and the soft substrate of the semi-finished lamp tube. Specifically, when the semi-finished lamp tube moves to the welding assembly, the lower driving member 63 will drive the positioning boss 64 to move upward, so that the positioning boss 64 and the welding boss 51 are located in the same horizontal plane, and then the tube pushing mechanism will push the semi-finished lamp tube toward the positioning boss 64, so that the semi-finished lamp tube and the positioning boss 64 are abutted and positioned. At this time, the soft substrate of the semi-finished lamp tube will be paired with the single board on the welding boss 51, so as to facilitate welding of the welding rod 62. Similarly, this welding and positioning process does not require manual participation and can be completed through the welding assembly. That is, the automatic positioning welding equipment for the LED soft substrate lamp tube light source bar of the present invention realizes automated positioning welding, improves production efficiency, and liberates labor.

[0044] Reference Figure 4 As a preferred embodiment, the single-row panel separation mechanism includes a rotating plate 21, a single-row telescopic mechanism 22, a push plate mechanism 23 and a single-row placement table 24; the fixed end of the single-row telescopic mechanism 22 is connected to the base 100, the telescopic end of the single-row telescopic mechanism 22 is hinged to the first end of the rotating plate 21, and the second end of the rotating plate 21 opposite to the first end is rotatably connected to the base 100; a limiting plate is arranged above the second end of the rotating plate 21, and a gap is left between the limiting plate and the rotating plate 21, and the gap is suitable for passing the entire plate; the push plate mechanism 23 is arranged on the rotating plate 21, and is used to push the entire plate to move toward the second end of the rotating plate 21; the single-row placement table 24 is arranged at the second end of the rotating plate 21, and is used to place a single row of panels.

[0045] That is, in the present invention, the single-row board splitting mechanism divides the whole board into single-row boards in the above manner. Specifically, in the initial state, the rotating plate 21 is in a horizontal state, and the whole board is located on the rotating plate 21. The whole board is pushed toward the second end of the rotating plate 21 by the push plate mechanism 23, so that the whole board at the front end is located on the single-row placement table 24, and then the rotating plate 21 is rotated by the single-row telescopic mechanism 22, and finally the front end of the whole board will become a single-row board. The above process completes the change from the whole board to the single-row board.

[0046] Reference Figure 4 Preferably, the pushing mechanism includes a linear drive mechanism 31 and a protruding plate 32; a strip groove is provided on the single-row placement table 24 along its length direction, the first end of the protruding plate 32 is connected to the driving end of the linear drive mechanism 31, and the second end of the protruding plate 32 is suitable for moving in the strip groove to push the single-row plate to move along the single-row placement table 24. Specifically, the linear drive mechanism 31 is a linear motor or a cylinder. That is, in the present invention, after the single-row plate is located on the single-row placement table 24, the linear drive mechanism 31 can drive the protruding plate 32 to move in the strip groove, so that the protruding plate 32 abuts against the end of the single-row plate to push the single-row plate to move.

[0047] Preferably, the single-piece board separation mechanism includes a vertical cylinder 41, an abutment block 42, a mounting plate 43, a horizontal driving member 44, a clamping member, and a horizontal cylinder 46; the fixed end of the vertical cylinder 41 is connected to the base 100, and the telescopic end of the vertical cylinder 41 is connected to the abutment block 42, and the abutment block 42 is located at one end of the single-row placement table 24 close to the mainboard conveying member; the horizontal driving member 44 is suitable for driving the mounting plate 43 to move along the conveying direction of the mainboard conveying member, the first end of the horizontal cylinder 46 is hinged to the mounting plate 43, and the second end of the horizontal cylinder 46 is hinged to the clamping member; the clamping member is located above the abutment block 42, and the clamping member includes two clamping plates 45 arranged opposite to each other, and the relative position between the two clamping plates 45 is adjustable. That is, in the present invention, the single-piece board separation mechanism separates the single-row board into a single board and transports the single board to the mainboard conveying member specifically through the above-mentioned method.

[0048] The specific process is as follows: when the linear drive mechanism 31 pushes the single-row plate to move on the single-row placement table 24, the vertical cylinder 41 pushes the abutment block 42 upward, and when the single-piece plate abuts against the abutment block 42, the positioning of the single-row plate is completed, and the linear drive mechanism 31 retracts. At this time, the front end of the single-row plate is located between the two clamping plates 45. When the horizontal cylinder 46 works, it drives the clamping plate member to rotate, thereby dividing the single-row plate into single plates (the effect is similar to breaking), and then the horizontal drive member 44 drives the clamping plate member to move above the welding boss 51. At this time, the distance between the two clamping plates 45 becomes larger, so that the single plate is placed on the welding boss 51.

[0049] Preferably, horizontal grooves 451 are provided on the opposite sides of the two clamping plates 45. By providing the horizontal grooves 451, the single board can be better fixed between the two clamping plates 45, thereby ensuring the reliability of the present invention.
