[0027] The automatic weighing and glue-breaking device according to an embodiment of the present invention will be specifically described below with reference to the drawings.

[0028] As Figures 1 to 3 shown, the automatic weighing and glue-breaking device according to an embodiment of the present invention includes: a weighing and wind-proof device 2, in which a first accommodation cavity is defined; a weighing device 1, which is arranged in the first accommodation cavity; a fluid segmentation device 4, which is arranged above the weighing and wind-proof device 2, and the fluid segmentation device 4 has a second accommodation cavity, and the second accommodation cavity is communicated with the first accommodation cavity; a fluid receiving container 3, which is arranged in the second accommodation cavity, the fluid receiving container 3 is located above the weighing device 1, and the fluid receiving container 3 has two states of glue-breaking and weighing. When the fluid receiving container 3 is in the glue-breaking state, the fluid receiving container 3 moves upward to receive glue. When the fluid receiving container 3 is in the weighing state, the fluid receiving container 3 moves downward and is placed on the weighing device 1 to weigh the glue. The structure of the present invention is simple. By placing the weighing device 1 and the fluid receiving container 3 in the accommodation cavity, it is ensured that there is no interference during the weighing process, and the fluid segmentation device 4 is used to segment the glue, ensuring that the amount of dispensed glue measured each time is more accurate.

[0029] According to an embodiment of the present invention, as Figure 1As shown, the weighing and windproof device 2 includes: a bottom plate 21 and a windproof cover 22. The weighing device 1 is disposed on the upper surface of the bottom plate 21; the windproof cover 22 is covered above the weighing device 1, and the windproof cover 22 is hermetically connected to the edge of the bottom plate 21. The upper end of the windproof cover 22 has an opening, and the fluid segmentation device 4 is disposed on the opening.

[0030] According to an embodiment of the present invention, as Figure 2 and Figure 3 shown, the fluid segmentation device 4 includes: a sealing base 411, a sealing cover 47, a weighing pan 412, a clamping ring 48, and a z-direction movement cylinder 41. The sealing base 411 is disposed at the opening, and a through hole is formed in the middle of the sealing base 411; the sealing cover 47 is located on the sealing base 411, and the lower end of the sealing cover 47 is disposed in the through hole. The sealing cover 47 has an upper opening and a lower opening, and an inner peripheral edge of the lower opening bulges inward to form a convex platform 47a; the weighing pan 412 is disposed in the sealing cover 47. When the fluid receiving container 3 is in a glue-breaking state, the weighing pan 412 is clamped on the convex platform 47a; the clamping ring 48 is sleeved on the sealing cover 47; one end of the z-direction movement cylinder 41 is disposed on the sealing base 411, and the other end of the z-direction movement cylinder 41 is connected to the clamping ring 48 through a cylinder connection block 42 to drive the sealing cover 47 to move up and down.

[0031] According to an embodiment of the present invention, as Figure 3 shown, the fluid receiving container 3 is disposed on the weighing pan 412. The fluid receiving container 3 includes: an outer conical surface 32 and an inner conical surface 31. The diameter of the outer conical surface 32 decreases from top to bottom; the diameter of the inner conical surface 31 increases from top to bottom. The inner conical surface 31 is disposed inside the outer conical surface 32, and the lower edge of the inner conical surface 31 is connected to the lower edge of the outer conical surface 32. A glue accommodating cavity is formed between the inner conical surface 31 and the outer conical surface 32. Further, the upper edge of the inner conical surface 31 is higher than the upper edge of the outer conical surface 32, and both the inner conical surface 31 and the outer conical surface 32 are conical table surfaces. Compared with a straight cylindrical surface, the conical table surface is more likely to contact the glue, and the glue is more likely to fall along the inner conical surface 31 or the outer conical surface 32 during glue breaking; at the same time, the upper space of the glue accommodating cavity formed between the inner conical surface 31 and the outer conical surface 32 is larger, so that the glue head will not collide with the inner conical surface 31 or the outer conical surface 32.

[0032] According to an embodiment of the present invention, as Figure 2 and Figure 3 shown, the fluid segmentation device 4 further includes: a weighing cover 45. The weighing cover 45 is disposed at the upper opening. A glue-breaking port 45a is formed on the weighing cover 45. The orthographic projection of the center point of the glue-breaking port 45a falls on the inner conical surface 31. An elastic ring 44 is further disposed on the glue-breaking port 45a. The elastic ring 44 buffers the glue head to avoid hard contact between the glue head and the glue-breaking port 45a. Such a design makes the center of the glue head above the inner conical surface 31 when the glue head enters the glue-breaking port 45a for glue breaking, and the glue falls on the inner conical surface 31 and slides down along the inner conical surface 31.

[0033] According to an embodiment of the present invention, the circumferential side surface of the weighing cover 45 is connected to the inner circumferential surface of the upper opening. Two annular grooves 45b and a positive pressure groove 45d are provided on the circumferential side surface of the weighing cover 45, and the positive pressure groove 45d is located between the two annular grooves 45b.

[0034] According to a preferred embodiment of the present invention, as Figure 3 shown, an air expansion hole 45f and a plurality of air guide holes 45e are provided on the weighing cover 45. The air expansion hole 45f is located directly below the glue breaking port 45a, and the air expansion hole 45f is connected to the glue breaking port 45a. The air expansion hole 45f is a flared opening facing downward; the plurality of air guide holes 45e are arranged in a circular array with the center point of the glue breaking port 45a as the center. One end of the air guide hole 45e is connected to the air expansion hole 45f, and the other end of the air guide hole 45e is connected to the positive pressure groove 45d. By introducing gas through the positive pressure groove 45d and using the air guide holes 45e to introduce the gas into the air expansion hole 45f, the flared opening can concentrate and eject the gas downward, ensuring that when the gas moves downward, the glue is peeled off from the glue head.

[0035] According to an embodiment of the present invention, as Figure 2 shown, the fluid segmentation device 4 further includes: a positive pressure blowing joint 46 and a vacuum negative pressure joint 49. The positive pressure blowing joint 46 is connected to the positive pressure groove 45d; the vacuum negative pressure joint 49 is provided at the lower part of the outer conical surface 32 and is connected to the glue accommodating cavity. By blowing positive pressure gas from the glue head and sucking negative pressure gas from the glue accommodating cavity respectively, it ensures that the glue moves along the downward flow direction of the gas, facilitating the peeling of the glue from the glue head.

[0036] According to an embodiment of the present invention, as Figure 3 shown, the fluid segmentation device 4 further includes: two first sealing rings 43 and a second sealing ring 410. One first sealing ring 43 is provided in each annular groove 45b; the second sealing ring 410 is provided between the sealing cover 47 and the sealing base 411. By providing the first sealing ring 43 and the second sealing ring 410, it ensures that during the glue breaking and weighing processes, the inside of the sealing cover 47 and the windproof cover 22 is always in a windless state, avoiding external interference and ensuring accurate measurement results.

[0037] During operation, the z-direction moving cylinder 41 drives the sealing cover 47 to move upward, causing the convex platform 47a to lift the weighing pan 412 and the fluid receiving container 3 upward. Then, the glue head extends into the glue breaking port 45a and enters the air expansion hole 45f. The positive pressure blowing joint 46 and the vacuum negative pressure joint 49 work. Through one blowing and one sucking, the glue on the glue head is smoothly introduced into the fluid receiving container 3. Subsequently, the positive pressure blowing joint 46 and the vacuum negative pressure joint 49 stop working, and the z-direction moving cylinder 41 moves downward, causing the weighing pan 412 and the fluid receiving container 3 to fall onto the weighing device 1 for weighing.
