[0003] Current glue dispensing devices consist of a single-component dispensing valve and a mixing pipe connected to its output end. They can only dispense single-component glue and cannot rotate, thus failing to meet production requirements. Therefore, there is an urgent need to develop a new type of glue dispensing device.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0030] Example 1: Refer to Figures 1-6 As shown, this utility model discloses a dual-channel rotary dispensing mechanism, comprising:

[0031] The glue dispensing base 1 has a central through hole 11 and two glue inlet holes 12 that are vertically connected to the central through hole.

[0032] Drive source 2 is connected to glue dispensing base 1;

[0033] A rotating dispensing shaft 3 is coaxially disposed in the central through hole 11 and rotatably connected to the glue dispensing base 1. Two semi-circular grooves 31 are coaxially arranged on the side of the rotating dispensing shaft 3, which are spaced apart along their length. The positions of the two grooves 31 correspond to the positions of the two glue inlet holes 12, and a through hole 32 is opened at the bottom of each groove 31. One end of the rotating dispensing shaft 3 is coaxially connected to the output shaft of the drive source 2, and the other end is provided with two glue dispensing holes 33 that extend into the interior of the rotating dispensing shaft 3 and are respectively connected to the two through holes 32.

[0034] A two-component dispensing valve 4 is connected to the dispensing base 1, and the two output ports of the two-component dispensing valve 4 are respectively connected to two glue inlet holes 12.

[0035] Specifically, the two components of adhesive from the two outlets of the two-component dispensing valve 4 enter the two grooves 31 through the inlet hole 12, and then enter the two outlet holes 33 through the through holes 32 at the bottom of the grooves 31. Finally, they enter the mixing tube 6 connected below the rotating dispensing shaft 3 for mixing, and are then discharged from the dispensing nozzle 61 to a predetermined position on the frame of the photovoltaic panel. It should be noted that the mixing tube 6 and the dispensing nozzle 61 are standard parts and are replaced each time production begins. Therefore, two grooves 31 are provided on the rotating dispensing shaft 3 to isolate the two components of adhesive, preventing the two adhesives from mixing and solidifying inside the dispensing base 1 and the rotating dispensing shaft 3.

[0036] Specifically, the drive source 2 is used to drive the rotating dispensing shaft 3 to reciprocate 180 degrees, thereby driving the mixing pipe 6 connected to the rotating dispensing shaft 3 to rotate, so that the glue nozzle 61 can rotate to the position corresponding to the two opposing frame sides, realizing synchronous glue application to the double frame sides; during the rotation of the rotating dispensing shaft 3, although the relative position of the through hole 32 on the rotating dispensing shaft 3 relative to the two glue inlet holes 12 changes, because the rotating dispensing shaft 3 has two grooves 31 respectively corresponding to the positions of the two glue outlet holes 33, the glue output by the two-component dispensing valve 4 can still enter the grooves 31 during the rotation of the rotating dispensing shaft 3, and thus enter the through hole 32 and the glue outlet hole 33, realizing glue injection during the rotation process.

[0037] This utility model discloses a dual-channel rotary glue dispensing mechanism, which includes a glue dispensing base 1 and a rotary dispensing shaft 3 rotatably connected together. A drive source 2 is provided at one end of the rotary dispensing shaft 3 to drive its rotation, thereby driving the mixing tube 6 connected to the other end of the rotary dispensing shaft 3. Two semi-circular grooves 31 are provided on the side of the rotary dispensing shaft 3, which correspond to the glue inlet holes 12 provided on the glue dispensing base 1, and glue dispensing holes 33 are provided in communication with the grooves 31. Stable glue dispensing can be achieved during the rotation of the mixing tube 6, thereby realizing the synchronous glue dispensing operation of the double-sided frame arranged in opposite directions.

[0038] Reference Figure 2 and Figure 3 As shown, at least one bearing 13 is coaxially arranged in the central through hole 11, and the rotating dispensing shaft 3 is rotatably connected to the glue dispensing base 1 through the bearing 13. Specifically, a step is provided in the central through hole 11, and the bearing 13 is installed in the central through hole 11 and limited by this step.

[0039] Reference Figure 6 As shown, three first sealing rings 5 ​​are coaxially sleeved on the rotating material distribution shaft 3, one of which is located between the two grooves 31, and the other two are located on the opposite sides of the two grooves 31.

[0040] Furthermore, three first annular grooves 34 are coaxially formed on the rotating dispensing shaft 3, and three first sealing rings 5 ​​are coaxially disposed in the three first annular grooves 34 respectively. Specifically, by setting the first sealing rings 5 ​​between the two grooves 31 and on the sides of the two grooves 31 that are far apart from each other, the different components of the adhesive entering the two grooves 31 are isolated, and the adhesive entering and leaving the adhesive base 1 is prevented from escaping. It is conceivable that opening the first annular grooves 34 at predetermined positions on the rotating dispensing shaft 3 can facilitate the installation of the first sealing rings 5.

[0041] Furthermore, the system includes a mixing tube 6, one end of which is connected to the end of the rotating dispensing shaft 3 with a glue outlet 33, and the other end is connected to a glue outlet 61, which is located on one side of the mixing tube 6. Specifically, the glue outlet 61 is positioned on one side of the output end of the mixing tube 6, meaning it is not coaxial with the mixing tube 6. This allows the glue outlet 61 to switch between two positions when the drive source 2 drives the rotating dispensing shaft 3 and the mixing tube 6 connected to it to rotate, thus fulfilling the glue dispensing requirement. Specifically, the end of the rotating dispensing shaft 3 furthest from the drive source 2 is its glue outlet, which extends out of the central hole 11 and is cylindrical in shape. The glue outlet is threaded, and the mixing tube 6 is connected to the glue outlet by a nut, facilitating installation and disassembly. More preferably, the output port of the mixing tube 6 is located on its side, and the output end of the mixing tube 6 is angled, so that the glue entering the mixing tube 6 will eventually converge towards the output port and be output from the glue outlet 61.

[0042] Reference Figure 6 As shown, the glue dispensing base 1 further includes two second annular grooves 14 coaxial with the two glue inlet holes 12, and a second sealing ring 7 is coaxially arranged in each of the two second annular grooves 14 to prevent the glue output by the two-component dispensing valve 4 from escaping from the opening of the glue inlet hole 12.

[0043] Furthermore, a partition plate located between the two glue outlet holes 33 is vertically connected to the end of the rotating dispensing shaft 3 away from the drive source 2. By setting the partition plate, the two different components of glue output are prevented from solidifying at the end of the rotating dispensing shaft 3, thereby preventing the glue outlet holes 33 from being blocked.

[0044] Furthermore, the dispensing base 1 is provided with two connecting seats, and the drive source 2 and the two-component dispensing valve 4 are respectively connected to one connecting seat.

[0045] Furthermore, the drive source 2 adopts a servo motor.

[0046] Example 2: This utility model also discloses a production line, including the dual-channel rotary dispensing mechanism as in Example 1.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
