[0002] With the continuous development of display technology, LCD screens are gaining increasing popularity in electronic devices due to their unique performance advantages. LCDs are constructed by placing a liquid crystal cell between two parallel glass substrates. TFTs (thin-film transistors) are located on the lower glass substrate, and color filters are located on the upper glass substrate. Signals and voltages on the TFTs control the rotation of the liquid crystal molecules, thereby controlling the polarized light emitted from each pixel and achieving the desired display.

[0034] The conveying mechanism 3 also includes an opening and closing door 28 hinged on both sides of the conveying trough 5. The positions where the two sets of opening and closing doors 28 fit together in the same conveying trough 5 are provided with magnetic blocks. The top of the body 1 is fixedly connected to a mounting bracket 29, and a fixing ring 30 is fixedly connected to the mounting bracket 29. The inner wall of the fixing ring 30 can fit and slide with the outer wall of the opening and closing door 28. The fixing ring 30 is provided with an opening and closing mouth 31 for controlling the opening and closing state of the opening and closing door 28. The body 1 is provided with a driving member 32 for driving the rotating drum 4 to rotate. A pushing member 42 is provided in the conveying trough 5 for closely fitting the display screen 39 and the cable 41 during the welding process. The driving member 32 includes a driving motor 36 fixedly installed in the body 1. The model of the driving motor 36 is preferably a 42BYGH34 stepping motor. The output end of the driving motor 36 is coaxially fixedly connected to the third gear 37, and the inner wall of the rotating drum 4 is fixedly connected to the third inner gear ring 38 meshing with the third gear 37.

[0035] The pushing member 42 includes a pushing plate 43 installed in the conveying trough 5. The side of the pushing plate 43 close to the display screen 39 is made of elastic latex material. The side of the pushing plate 43 is fixedly connected to a pushing rod 44. The side of the body 1 is provided with a groove 45 for releasing the resistance state of one end of the pushing rod 44. The side of the pushing plate 43 is fixedly connected to a tension spring 46 fixedly connected to the outer wall of the rotating cylinder 4, which facilitates the close fitting of the display screen 39 and the cable 41 during the welding process.

[0036] The lifting member 18 includes multiple groups of threaded rods 33 rotatably connected to the rotating cylinder 4. The threaded rods 33 pass through the lifting ring 9 and are threadedly connected to the lifting ring 9. The bottom end of the threaded rod 33 is coaxially fixedly connected to the second gear 34. The outer wall of the rotating cylinder 4 is rotatably connected to the second inner gear ring 35 that is meshed with multiple groups of second gears 34. The top surface of the bevel gear ring 27 and the outer walls of the first inner gear ring 14 and the second inner gear ring 35 are all made of non-slip rubber material.

[0037] In this embodiment, the third gear 37 is driven by the driving motor 36 so that the third inner gear ring 38 drives the rotating cylinder 4 to intermittently rotate and switch positions. When the opening and closing door 28 is aligned with the opening and closing port 31, the opening and closing door 28 can be opened to both sides, and the welded display screen 39 and PCB board 40 are taken out. After taking them out, the opening and closing door 28 is closed. The opening and closing door 28 is magnetically closed by the magnetic block. As the rotating cylinder 4 rotates, the opening and closing door 28 rotates into the fixed ring 30, and the outer wall of the opening and closing door 28 slides in contact with the inner wall of the fixed ring 30. , preventing the opening and closing door 28 from opening, and at this time, the display screen 39 to be welded can be inserted vertically from the top of the conveying trough 5 into the conveying trough 5, and the position of the groove 45 is set at the position where the display screen 39 needs to be inserted, so that the tension spring 46 at this position can pull the push plate 43 back, fully opening the conveying trough 5, and then, as the rotating cylinder 4 rotates, the push rod 44 moves away from the groove 45, and the push rod 44 is resisted by the inner wall of the body 1, and the push plate 43 can be pushed to push the display screen 39 to the side of the opening and closing door 28 for resistance.

[0038] Place the PCB board 40 in the conveying frame 8, open the rotating frame 10, place the cable 41 in the positioning groove 11, and clamp the cable 41 by the rotating frame 10. Then, since one side of the display screen 39 is pushed by the pushing plate 43, the display screen 39 is fitted to the side of the cable 41. At this time, the welding point on the display screen 39 can be fitted with the cable 41 on the side of the conveying frame 8, which improves the stability of the welding process. When the rotating cylinder 4 drives the docked and fixed display screen 39 and PCB40 to the position of the arc welding machine 2, the welding operation can be carried out. The equipment occupies a small area, for example, Figure 1As shown in the figure, there are six groups of conveying troughs 5. At this time, the equipment can convey and weld six groups of display screens 39. If it is placed horizontally, the top surface area of ​​the equipment can only hold about two groups of display screens 39. In order to improve the welding efficiency, multiple groups of arc welding machines 2 (such as two groups) can be set adjacent to each other, and the driving motor 36 can be controlled to make the rotating cylinder 4 rotate the angle of two conveying troughs 5 each time, so that the two groups of arc welding machines 2 can be welded synchronously, and the rest of the positions are used for loading and unloading operations. At this time, the opening and closing port 31 can be opened to the size of two groups of conveying troughs 5. The equipment avoids the bending of the display screen 39 due to uneven force during transportation by placing and conveying the display screen 39 vertically.

[0039] It should be noted that vertical soldering has several advantages over traditional horizontal soldering: because hot air rises naturally, vertical placement aligns the direction of heat conduction with the natural flow of air, helping to form a good heat dissipation channel and reduce heat accumulation on the display and PCB board, thereby improving the heat dissipation performance of the display and PCB board and extending the service life of electronic components; during vertical soldering, due to the effect of gravity, the molten solder will flow more smoothly to the solder joint, reducing the phenomenon of tin ball splashing. During horizontal soldering, the solder may flow on the surface of the display and PCB board, easily forming tin balls, which not only affects the appearance of the solder joint, but may also cause problems such as short circuits.

[0040] When it is necessary to switch the display screen 39 to be welded, the third bevel gear 26 is driven to rotate by rotating the bevel gear ring 27, so that the worm 25 drives the worm wheel 20 to drive the second screw rods 23 on both sides to rotate, thereby driving the driving block 22 and the gear rod 21 to slide horizontally toward each other along the inner wall of the conveying trough 5, changing the spacing between the gear rods 21, so that the gear rod 21 can stably limit the conveying of the display screen 39, and by rotating the first inner gear ring 14, the first gear 15 can be driven to rotate, and the first gear 15 drives the first bevel gear 16 to drive the second bevel gear 17 to rotate, so that the first screw rod 13 drives the conveying frame 8 can be adjusted by sliding horizontally along the inner wall of the lifting ring 9, and the horizontal position of the cable 41 can be adjusted accordingly according to the position of the welding point of the display screen 39. By rotating the second inner gear ring 35 to drive the second gear 34 to rotate the threaded rod 33, the lifting ring 9 can be driven to be raised and lowered, so that the conveying frame 8 can adjust the position of the cable 41 to the required height. This adjustment is a synchronous adjustment of the structure inside multiple groups of conveying troughs 5. After the adjustment is completed, the welding position of the arc welding machine 2 is adjusted according to the position of the welding point to complete the overall operation process. The synchronous adjustment is more convenient and efficient, which improves the subsequent installation efficiency and welding efficiency.
