[0035] In the production process of long cylindrical products, cursor products are generally produced first, and then the brand or pattern labeling operation is carried out by silk screen printing or stickers. This is not only not environmentally friendly, but also increases production costs and is difficult to meet production needs. Compared with the prior art, this application realizes the automated production process of high-speed embedding of multiple labels simultaneously through the cooperation of a manipulator, a label feeding device and an injection molding machine. This simplifies the labeling workflow, improves production efficiency, and reduces production costs.

[0036] The embodiment of the present application provides a top-entry in-mold labeling device for long cylindrical products, including: an injection molding machine 100, a label feeding device 200 and a robot 300.

[0037] The specific structure of the top-entry in-mold labeling equipment for long cylindrical products is described in detail below.

[0038] like Figures 1 to 3 As shown, an injection molding machine 100; a label feeding device 200, including a tooling frame 210, a label supply mechanism 220, a label taking mechanism 230 and an electrostatic mechanism 240, the tooling frame 210 is arranged on one side of the injection molding machine 100, and a mounting frame 211 is arranged on the tooling frame 210, the label supply mechanism 220 and the label taking mechanism 230 are both arranged in the mounting frame 211, the label supply mechanism 220 corresponds to the label taking mechanism 230 one by one, the label taking mechanism 230 is located above the label supply mechanism 220, and the electrostatic mechanism 240 is located above the mounting frame 211; a manipulator 300, arranged on the injection molding machine 100, and a label embedding fixture 310 is provided on the manipulator 300.

[0039] The manipulator 300 is used to drive the label embedding jig 310 to move back and forth between the injection molding machine 100 and the label feeding device 200. The label supply mechanism 220 is used to place the label. The label taking mechanism 230 is used to take the label from the label supply mechanism 220, and then roll the label and place it on the label embedding jig 310 of the manipulator 300. The electrostatic mechanism 240 is used to perform electrostatic operation on the label on the label embedding jig 310. The injection molding machine 100 is used to perform injection molding processing on the label that has completed the electrostatic operation and generate a long cylindrical product.

[0040] The manipulator 300 is a three-axis moving mechanism, which can drive the embedding fixture 310 to move along the X-axis, Y-axis, and Z-axis directions. Among them, the X-axis, Y-axis, and Z-axis are perpendicular to each other, the X-axis corresponds to the left and right directions of the spatial coordinate axis, the Y-axis corresponds to the front and back directions of the spatial coordinate axis, and the Z-axis corresponds to the up and down directions of the spatial coordinate axis. In this way, the manipulator 300 can realize the multi-directional stable and fast movement of the embedding fixture 310.

[0041] There are two label supply mechanisms 220 and two label taking mechanisms 230, that is, one label supply mechanism 220 corresponds to one label taking mechanism 230, and together they form a label feeding assembly. In this way, the two label feeding assemblies can work independently without affecting each other, so as to realize rapid label feeding onto the label embedding fixture 310.

[0042] like Figures 1 to 3 As shown, in some embodiments, the embedding fixture 310 includes a connection seat 311, a first mounting plate 312 and a embedding unit 313, the connection seat 311 is connected to the manipulator 300, the first mounting plate 312 is connected to the connection seat 311, and the embedding unit 313 has a plurality of embedding units 313 and is spaced apart on the first mounting plate 312. There are four embedding units 313.

[0043] The label embedding unit 313 is disposed toward the label feeding device 200 , so that when the robot 300 drives the label embedding unit 313 to approach the label feeding mechanism 220 and the label taking mechanism 230 , the distance between the label embedding unit 313 and the label taking mechanism 230 can be shortened, thereby realizing rapid label loading.

[0044] Specifically, there are four label embedding units 313, which are the first label embedding unit 313, the second label embedding unit 313, the third label embedding unit 313 and the fourth label embedding unit 313 in order. Since there are two label supply mechanisms 220 and two label taking mechanisms 230, one label supply mechanism 220 and one label taking mechanism 230 form a label loading component, that is, there are a first label loading component and a second label loading component. When loading labels, the first label loading component and the second label loading component each take a label, and the first label loading component loads the label to the first label embedding unit 313, and the second label loading component loads the label to the third label embedding unit 313. Subsequently, the first label loading component and the second label loading component each take a label, and the first label loading component loads the label to the second label embedding unit 313, and the second label loading component loads the label to the fourth label embedding unit 313. In this way, the four label embedding units 313 are loaded with labels, thereby improving the efficiency of label loading.

[0045] like Figures 1 to 3 As shown, in some embodiments, the embedding unit 313 includes a base 3131, an air pipe connector 3132 and a PE mold 3133. The base 3131 is disposed on the first mounting plate 312. The air pipe connector 3132 and the PE mold 3133 are both connected to the base 3131. The PE mold 3133 is located on the side of the base 3131 facing away from the first mounting plate 312.

[0046] The PE mold 3133 is roughly a cylindrical structure, which makes it convenient for the label to be wound on the PE mold 3133 and for the PE mold 3133 to enter the mold cavity of the injection molding machine 100 .

[0047] When the label is loaded, the label is placed on the PE mold 3133 , and then negative pressure is generated on the surface of the PE mold 3133 , causing the label to be wound around the PE mold 3133 .

[0048] like Figures 1 to 3 As shown, in some embodiments, the electrostatic mechanism 240 includes a second mounting plate 241 and an electrostatic ring 242. The second mounting plate 241 is arranged on the tooling frame 210 and is located above the label supply mechanism 220. A plurality of first perforations are arranged at intervals on the second mounting plate 241. The electrostatic ring 242 is connected to the second mounting plate 241. A plurality of second perforations are arranged at intervals on the electrostatic ring 242. The first perforations correspond to the second perforations one by one.

[0049] The number of the first perforation and the second perforation are both four, which is the same as the number of the label embedding units 313. The apertures of the first perforation and the second perforation are larger than the diameter of the PE mold 3133, so that the PE mold 3133 can be inserted into the second perforation and the first perforation in sequence. During the electrostatic operation, the manipulator 300 drives the label embedding fixture 310 to approach the electrostatic mechanism 240, so that the label embedding unit 313 passes through the electrostatic ring 242, and then the label surface on the label embedding unit 313 is charged with static electricity, so that it is convenient for the subsequent label to be attached to the mold cavity of the injection molding machine 100.

[0050] like Figures 1 to 3 As shown, in some embodiments, the label supply mechanism 220 includes a label bin bottom plate 221, a positioning column 222, a lifting cylinder 223 and a label push plate 224. The label bin bottom plate 221 is arranged in the mounting frame 211. There are a plurality of positioning columns 222 and they are spaced apart on the label bin bottom plate 221. The lifting cylinder 223 is installed on the label bin bottom plate 221. The label push plate 224 is connected to the output end of the lifting cylinder 223, and the label push plate 224 is located between the positioning columns 222. In this way, the label bin bottom plate 221 cooperates with the positioning columns 222 to realize the positioning and placement of labels, and the lifting cylinder 223 cooperates with the label push plate 224 to realize the orderly rise of labels and be absorbed by the label taking mechanism 230.

[0051] like Figures 1 to 3 As shown, in some embodiments, the label picking mechanism 230 includes a linear moving motor 231, a moving cylinder 232, a label picking plate 233 and a suction nozzle 234. The linear moving motor 231 has two and is symmetrically arranged in the mounting frame 211. The moving cylinder 232 has two and corresponds to the linear moving motor 231 one by one. The moving cylinder 232 is connected to the moving end of the linear moving motor 231. The label picking plate 233 is connected to the output end of the moving cylinder 232. The suction nozzle 234 is distributed on the label picking plate 233 at intervals. In this way, the suction nozzle 234 can suck the label in the label supply mechanism 220, and the linear moving motor 231 can drive the label to approach the label embedding fixture 310, so as to place the label on the label embedding unit 313. The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any person skilled in the art can make many possible changes and modifications to the technical solution of this application by using the above disclosed methods and technical contents without departing from the scope of the technical solution of this application, or modify it into an equivalent embodiment of equivalent changes. Therefore, all equivalent changes made according to the shape, structure and principle of this application without departing from the content of the technical solution of this application should be included in the protection scope of this application.
