[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figure 1-Figure 3 As shown, a dispensing machine with an anti-overflow edge includes a dispensing head 1 and an anti-overflow glue component 2. The anti-overflow glue component 2 is plugged into the bottom of the outer wall of the dispensing head 1. The anti-overflow glue component 2 includes a plug-in shell 201, a rotating motor 202, a rotating plate 203, a first glue outlet 204, a second glue outlet 205 and a third glue outlet 206. The rotating motor 202 is fixed to the surface of the plug-in shell 201, and the bottom output end of the rotating motor 202 is connected to the rotating plate 203. The surface of the rotating plate 203 is annular and is provided with a first glue outlet 204, a second glue outlet 205 and a third glue outlet 206 in sequence. The first glue outlet 204 is a single-hole structure, and the top of the first glue outlet 204 is adapted to the bottom of the dispensing head 1. The second glue outlet 205 and the third glue outlet 206 are porous structures, and the apertures of the second glue outlet 205 and the third glue outlet 206 are smaller than the aperture of the first glue outlet 204.

[0023] The specific operation is as follows: the number of holes between the first glue outlet 204, the second glue outlet 205 and the third glue outlet 206 are different, and the hole diameters are also different. The first glue outlet 204 is a single hole with a large hole diameter, while the second glue outlet 205 is a multi-hole with a small hole diameter. The number of holes in the third glue outlet 206 is more than that in the second glue outlet 205. For the purpose of dispensing, if an object with a larger adhesion area is required, that is, the bonding surface is larger than the hole diameter of the first glue outlet 204, the rotating motor 202 is used to drive the rotating plate 203 to rotate so that the first glue outlet 204 coincides with the bottom of the glue dispensing head 1. At this time, the glue passes through the glue dispensing head 1. The glue is discharged from the dispensing head 1 and the first glue outlet 204. When an object with a smaller bonding area needs to be bonded, that is, the bonding surface is larger than the edge diameter of the second glue outlet 205 or the third glue outlet 206, the second glue outlet 205 or the third glue outlet 206 is rotated to coincide with the bottom of the dispensing head 1. At this time, the glue passes through the dispensing head 1, the second glue outlet 205 or the third glue outlet 206 and is discharged in a multi-point shape and adheres to the surface of the product. When the object is pressed for bonding, there are gaps between the glue points, and the glue points can overflow when subjected to force, thereby preventing the glue from directly overflowing to the edge of the object.

[0024] like Figure 1-Figure 3 As shown, the anti-overflow glue component 2 also includes a torsion spring 207, and the torsion spring 207 is arranged in the middle of the bottom surface of the rotation plate 203. The anti-overflow glue component 2 also includes a glue breaking plate 208 and a magnetic edge 209. The surface of the torsion spring 207 is connected to the glue breaking plate 208, and the side of the glue breaking plate 208 is provided with a magnetic edge 209. The anti-overflow glue component 2 also includes a plug-in power board 210 and an electromagnet 211. The inner wall of the plug-in shell 201 is plugged with the plug-in power board 210, and the inner side of the plug-in power board 210 is plugged with the electromagnet 211.

[0025] The specific operation is as follows: the glue passes through the dispensing head 1 and then passes through the first glue outlet 204 or the second glue outlet 205 or the third glue outlet 206 to adhere to the specified position on the product surface. The glue dispensing mechanism controls the glue dispensing amount. At the same time, after each glue injection, the power board 210 is plugged in to disconnect the power supply to the electromagnet 211, so that the glue cut-off plate 208 rotates through the torsion spring 207 to adhere to the bottom surface of the rotating plate 203 and rotate a certain angle to cut off the glue discharged from the first glue outlet 204 or the second glue outlet 205 or the third glue outlet 206, thereby preventing the glue from Wire drawing, and after rotation, the power board 210 and the electromagnet 211 are plugged in to restore power. At this time, the magnetic edge 209 is affected by the magnetic force and pulls the glue cutting plate 208 to rotate in the opposite direction and reset to the side close to the electromagnet 211. At this time, the torsion spring 207 accumulates force and the first glue outlet 204 or the second glue outlet 205 or the third glue outlet 206 is exposed for the next glue dispensing. Constant temperature heating wires are embedded in the glue cutting plate 208 and the rotation plate 203 for constant temperature insulation to prevent the glue from solidifying on the surface of the glue cutting plate 208 and the rotation plate 203 and affecting the glue passing through.

[0026] like Figure 1 As shown, the surface of the dispensing head 1 is connected to the glue injection mechanism through a pipeline, and the top of the dispensing head 1 is connected to an electric telescopic rod 3, the back of the electric telescopic rod 3 is provided with an electric pulley 4, and the bottom of the electric pulley 4 is slidably connected to a bracket rail 5, and a conveyor belt 6 is provided on the inner side of the bottom of the bracket rail 5 below the dispensing head 1;

[0027] The specific operation is as follows: during the dispensing process, the product is placed on the surface of the conveyor belt 6 to be transferred to the bottom of the dispensing head 1. The dispensing head 1 is adjusted in height by extending and retracting the electric telescopic rod 3. During the dispensing process, the product is transmitted at a uniform speed through the conveyor belt 6, and the dispensing head 1 slides left and right along the top of the bracket slide rail 5 through the electric pulley 4 to adjust the dispensing position during the dispensing process.

[0028] In summary, if Figure 1-Figure 3 As shown, when the anti-overflow dispensing machine is used, first during the dispensing process, the product is placed on the surface of the conveyor belt 6 to be transferred to the bottom of the dispensing head 1, and the dispensing head 1 is adjusted in height by the extension and retraction of the electric telescopic rod 3. During the dispensing process, the product is uniformly transported through the conveyor belt 6, and the dispensing head 1 slides left and right along the top of the bracket slide rail 5 through the electric pulley 4 to adjust the dispensing position during the dispensing process;

[0029] For the purpose of glue dispensing, if an object with a larger adhesive area needs to be adhered, that is, the adhesive surface is larger than the aperture of the first glue outlet 204, the rotating motor 202 drives the rotating plate 203 to rotate so that the first glue outlet 204 coincides with the bottom of the glue dispensing head 1. At this time, the glue passes through the glue dispensing head 1 and the first glue outlet 204 and is discharged;

[0030] When an object with a smaller bonding area needs to be bonded, that is, the bonding surface is larger than the side diameter of the second glue outlet 205 or the third glue outlet 206, the second glue outlet 205 or the third glue outlet 206 is rotated to overlap with the bottom of the glue dispensing head 1. At this time, the glue passes through the glue dispensing head 1, the second glue outlet 205 or the third glue outlet 206 and is discharged in a multi-point shape and adheres to the surface of the product. When the object is pressed for bonding, there are gaps between the glue points, and the glue points can overflow when subjected to force, thereby preventing the glue from directly overflowing outside the edge of the object.

[0031] The glue injection mechanism controls the glue output. At the same time, after each glue injection, the power board 210 is plugged in to disconnect the power supply to the electromagnet 211, so that the glue cut-off plate 208 rotates through the torsion spring 207 to stick to the bottom surface of the rotation plate 203 and rotates a certain angle to cut off the glue discharged from the first glue outlet 204 or the second glue outlet 205 or the third glue outlet 206, thereby preventing the glue from drawing. After the rotation, the power board 210 and the electromagnet 211 are plugged in to resume power. At this time, the magnetic edge 209 is affected by the magnetic force and pulls the glue cut-off plate 208 to rotate in the opposite direction and reset to the side close to the electromagnet 211. At this time, the torsion spring 207 accumulates power and the first glue outlet 204 or the second glue outlet 205 or the third glue outlet 206 is exposed for the next glue dispensing.

[0032] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
