Detailed Description of the Preferred Embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-5 , the present utility model provides a technical solution: a glue storage device for a die bonder that can prevent glue from solidifying, including a base 1, a protective shell 2, a first motor 3, a rectangular plate 4, a rubber tray 5, a side plate 6, a first electric telescopic rod 7, a top plate 8, a rubber cylinder 9, a cylinder cover 10, a second motor 11, a rectangular rod 12, a pressing plate 13, an annular groove 14, a second electric telescopic rod 15, a limiting block 16, a heating sheet 17 and a rubber outlet pipe 18. Open the cylinder cover 10 on the rubber cylinder 9, put glue into the inside of the rubber cylinder 9, and then cover the cylinder cover 10. The second motor 11, rectangular rod 12, pressing plate 13, annular groove 14, second electric telescopic rod 15 and limiting block 16 on the cylinder cover 10 enter the inside of the rubber cylinder 9;

[0028] The second motor 11 drives the rectangular rod 12 to rotate. Since the rectangular rod 12 passes through the rectangular slot in the middle of the pressing plate 13, the rotation of the rectangular rod 12 drives the pressing plate 13 to rotate. The rotation of the rectangular rod 12 and the pressing plate 13 is used to stir the colloid inside the rubber cylinder 9. The electric heating sheet 17 is connected to the power supply, and under the action of the electric heating sheet 17, the colloid is heated. Through heating and stirring, the coagulation of the colloid is avoided. When the rectangular rod 12 rotates, the limiting block 16 remains stationary, and the pressing plate 13 and the annular groove 14 rotate outside the limiting block 16. When the second electric telescopic rod 15 does not work, the height of the limiting block 16 is fixed. Since the limiting block 16 with a "T"-shaped cross-section is located in the annular groove 14 of the pressing plate 13, the limiting block 16 suspends the pressing plate 13, so that the height position of the pressing plate 13 is fixed;

[0029] Turn on the second electric telescopic rod 15. The second electric telescopic rod 15 drives the limiting block 16 and the pressing plate 13 to move downward. The pressing plate 13 moves downward outside the rectangular rod 12, squeezing the colloid, so that the colloid enters the inside of the glue tray 5 through the glue outlet pipe 18. A protective shell 2 is fixed inside the base 1, and a first motor 3 is fixed inside the protective shell 2. The output end of the first motor 3 is fixed with a rectangular plate 4. The first motor 3 inside the protective shell 2 drives the rectangular plate 4 and the glue tray 5 to rotate, so that the colloid is evenly injected into the glue tray 5, as Figure 1 、 Figure 2 and Figure 5 shown. Since the rectangular plate 4 is snap-connected to the glue tray 5, lifting the glue tray 5 upward so that the glue tray 5 leaves the rectangular plate 4 can remove the glue tray 5;

[0030] A first electric telescopic rod 7 is arranged on the right side of the side plate 6, and the output end of the first electric telescopic rod 7 is fixed with a top plate 8. The lower surface of the first electric telescopic rod 7 is fixedly connected to the upper surface of the base 1. The first electric telescopic rod 7 drives the top plate 8 and the rubber cylinder 9 to move downward to adjust the height of the rubber cylinder 9;

[0031] Since the connection method of the glue outlet pipe 18 and the rubber cylinder 9 is a threaded connection, rotating the glue outlet pipe 18 can remove the glue outlet pipe 18 from the rubber cylinder 9, which is convenient for cleaning the glue outlet pipe 18. The above completes a series of operations of the glue storage device for the die bonder that can prevent colloid coagulation. The content not described in detail in this description belongs to the prior art well-known to those skilled in the art.

[0032] The standard parts used in the present invention can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machines, parts, and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.
