[0023] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] See also Figure 1-5 The invention discloses an automatic glue stirring machine, which is specially used for mixing and stirring component A and component B of LED potting glue.

[0025] In the embodiments of the present disclosure, Figure 1 and Figure 2 As shown, the automatic glue stirring machine includes a base 100, a mounting seat 200, a driving device 300, a rotating shaft 400, a stirring part 500 and a driving motor 600. Among them, the base 100 is used for support; the mounting seat 200 is arranged directly above the base 100; the driving device 300 is arranged on the base 100, and is used to drive the mounting seat 200 to move up and down; the rotating shaft 400 is rotatably arranged vertically on the mounting seat 200; the stirring part 500 includes a connecting seat 501, which is arranged at the lower end of the rotating shaft 400, and the length direction of the connecting seat 501 is perpendicular to the rotating shaft 400, and the two ends of the length direction of the connecting seat 501 are respectively provided with stirring shafts 502 extending vertically downward, and stirring blades 503 are arranged on the stirring shaft 502; the driving motor 600 is arranged on the mounting seat 200 and is transmission-connected with the rotating shaft 400.

[0026] When the automatic glue stirring machine is used for mixing and stirring the A component and the B component of the LED potting glue, first, the mounting seat 200 is moved upward so that the stirring part 500 is in a state away from the base 100; then, the A component and the B component of the LED potting glue can be loaded into a containing tank 800 in proportion; then the containing tank 800 is placed on the base 100 so that the containing tank 800 is directly below the stirring part 500; then the driving device 300 can drive the mounting seat 200 to move downward so that the stirring blade 503 extends into the containing tank 800; then the driving motor 600 drives the rotating shaft 400 to rotate, and the connecting seat 501 will rotate with the rotation of the rotating shaft 400, and the rotating connecting seat 501 will drive the stirring shafts 502 at both ends of the connecting seat 501 to rotate around each other in the containing tube, and then the stirring blades 503 start to move with the stirring shaft 502 to stir the LED potting glue in the containing tank 800.

[0027] like Figure 5 As shown, during the stirring process, two stirring shafts 502 will rotate around each other to drive the stirring blades 503 to stir. During the stirring process, the stirring working part used for stirring can move in a large range in the containing tank 800 and stir the LED potting glue, thereby effectively improving the stirring efficiency and better allowing component A and component B to be fully mixed.

[0028] In the disclosed embodiment, the driving device 300 includes two guide posts 301 vertically fixedly arranged on the base 100, the mounting seat 200 is connected to the guide posts 301 through a linear bearing 302, and a reciprocating driving device 303 is arranged on the base 100, and the movable part of the reciprocating driving device 303 is connected to the mounting seat 200. Among them, the reciprocating driving device 303 is a telescopic cylinder, the cylinder body of the telescopic cylinder is fixedly connected to the base 100, the front end of the telescopic shaft of the telescopic cylinder is the movable part, and the front end of the telescopic shaft of the telescopic cylinder is connected to the mounting seat 200. Then, the mounting seat 200 can be driven to move up and down by the telescopic cylinder.

[0029] In some embodiments, to facilitate control, a controller 700 may be provided to connect the control device of the telescopic cylinder telescopic control and the drive motor 600, and then the lifting and lowering of the mounting seat 200, the start and stop and the speed of the drive motor 600 may be controlled through the controller 700.

[0030] In the embodiment of the present disclosure, in order to more efficiently complete the mixing and stirring of the A component and the B component of the LED potting glue, the mounting seat 200 is provided with an upper mounting plate 201 connected to the driving device 300, and a lower mounting plate 202 fixedly connected to the upper mounting plate 201 is provided at the lower side of the upper mounting plate 201. The upper end of the rotating shaft 400 can be rotatably arranged on the lower mounting plate 202, and the driving motor 600 is fixedly arranged on the upper mounting plate 201. The output shaft of the driving motor 600 is connected to the upper end of the rotating shaft 400 through the coupling 401. Figure 3 As shown, the lower end of the rotating shaft 400 is rotatably connected to the connecting seat 501, and a first gear 504 is provided at the lower end of the rotating shaft 400. The upper end of the stirring shaft 502 is rotatably connected to the connecting seat 501, and a second gear 505 is provided at the upper end of the stirring shaft 502 for transmission meshing with the first gear 504.

[0031] During the rotation of the rotating shaft 400, due to the obstruction of the LED potting glue on the stirring blade 503 rotating around the rotating shaft 400, the rotation of the rotating shaft 400 can drive the stirring blade 503 and the stirring shaft 502 to rotate, and the rotating stirring blade 503 forms a stirring area alone; at the same time, the self-rotation of the stirring shaft 502 will also be obstructed by the LED potting glue, and the obstruction effect will be transmitted to the connecting seat 501 through the cooperation of the first gear 504 and the second gear 505, so that the connecting seat 501 can be driven to rotate relative to the containing tank 800 under the rotation of the rotating shaft 400. Therefore, during the stirring process, the self-rotation stirring of the stirring blade 503 and the stirring of the stirring blade 503 and the stirring shaft 502 rotating around the rotating shaft 400 exist simultaneously, thereby increasing the stirring range during stirring, enhancing the stirring effect during stirring, ensuring that the A component and the B component of the LED potting glue are fully mixed, and can also effectively reduce the stirring time, avoid high-speed and long-term stirring, and thus avoid the high temperature generated during the stirring process, resulting in shortened operation time and accelerated curing.

[0032] In the disclosed embodiment, considering the viscosity of the LED potting glue and the large resistance during stirring, in order to improve the stirring effect, the stirring blade 503 is flat and teardrop-shaped (not round), and the top end of the stirring blade 503 is fixedly connected to the bottom end of the stirring shaft 502.

[0033] In the embodiment of the present disclosure, three L-shaped positioning blocks 102 are provided on the base 100, one end of the positioning block 102 is connected to the base 100, and the other end extends vertically upward. The end of the positioning block 102 extending vertically upward is distributed in a semicircular range around the rotating shaft 400, and thus the vertical end of the positioning block 102 can be used to quickly position the containing tank 800, so that the containing tank 800 can be quickly and accurately placed in the correct position directly below the stirring part 500.

[0034] Furthermore, to facilitate installation and debugging, one end of the positioning block 102 connected to the base 100 extends in a direction away from the rotation axis 400, such as Figure 4 As shown, one end of the positioning block 102 connected to the base 100 is provided with a long hole 103 extending along the length direction, and the base 100 is provided with a threaded hole 101 opposite to the long hole 103. A screw 104 is provided in the threaded hole 101 and passes through the long hole 103 and then threadedly cooperates with the threaded hole 101 to fix the positioning block 102.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
