DETAILED DESCRIPTION

[0024] In order to describe the technical content, structural features, achieved purposes and effects of the application in detail, the technical solutions in the embodiments of the application will be described below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but are not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0025] The present application provides a die-forward labeling device, which is arranged on the front side of a target object to label or apply a film to the target object. In an embodiment of the present application, the die-forward labeling device is used as a labeling device to label in a mold cavity of a mold.

[0026] like Figure 1 、 2 As shown, the die-forward labeling device 100 includes: a machine body 10 , a label library group 20 installed on the machine body 10 , and a pasting module 30 .

[0027] The housing 10 is positioned in front of the mold and includes an outer box 1 and a first guide rail 2 mounted within the outer box 1. The outer box 1 defines a housing (not shown) for accommodating the pasting module 30. This housing has an opening at the rear end of the outer box 1 for the pasting module 30 to enter and exit. The first guide rail 2 extends from front to rear and has a first end 21 distal from the mold and a second end 22 proximal to the mold. The second end 22 extends to the rear of the housing and is located between the mold and the opening.

[0028] The label library assembly 20 includes a pair of label libraries 3, mounted on the left and right sides of the first guide rail 2. Each library 3 is used to store multiple labels 200. Each library 3 has an opening 31 for placing and removing labels 200, allowing labels 200 to be attached to the mold. The label library assembly 20 is located behind the opening, with the pair of library libraries 3 mounted at the rear end of the outer housing 1.

[0029] like Figure 1-4As shown, the laminating module 30 includes a base 4, a pair of rotating shafts 5 arranged opposite each other left and right, and a suction cup assembly 6 for adsorbing labels 200. The base 4 is transmission-connected to the first guide rail 2 so as to be movable back and forth along the first guide rail 2. In the present application, the base 4 enables the pair of rotating shafts 5 and the suction cup assembly 6 to move in the front-to-back direction and in the up-to-down direction relative to the first guide rail 2. The base 4 includes a translation bracket 41 and a lifting bracket 42. The translation bracket 41 slidably cooperates with the first guide rail 2 to be movable back and forth along the first guide rail 2. The lifting bracket 42 is mounted on the translation bracket 41 so as to be movable in the up-to-down direction. The pair of rotating shafts 5 are mounted on the lifting bracket 42. Each rotating shaft 5 extends in the front-to-back direction and is mounted on the lifting bracket 42 so as to be movable both left-to-right and rotatable about its own axis. At least one suction cup assembly 6 is mounted on one end of each rotating shaft 5 near the mold. In the present embodiment, a pair of suction cup assemblies 6 are arranged at intervals in the front-to-back direction on each rotating shaft 5. The pair of suction cup assemblies 6 adsorb labels in the front-to-back direction, thereby stabilizing the labels and effectively preventing them from collapsing during mold insertion. When the translation bracket 41 moves backward along the first guide rail 2, the suction cup assembly 6 on the pair of rotating shafts 5 moves backward toward the mold; when the pair of rotating shafts 5 rotate around their own axis, the suction cup assembly 6 on each rotating shaft 5 rotates around the axis along with the rotating shaft 5; when the pair of rotating shafts 5 move respectively in the left and right directions, the suction cup assembly 6 on each rotating shaft 5 moves along the left and right directions along with the rotating shaft 5.

[0030] In an embodiment of the present application, a pair of label libraries 3 are located below the pasting module 30, and each label library 3 has an outer frame 32 and a label pushing assembly 33. The outer frame 32 has a accommodating cavity for accommodating multiple labels 200, and the opening 31 is opened at the top of the outer frame 32 and is connected to the accommodating cavity. The label pushing assembly 33 is installed at the bottom of the accommodating cavity and is arranged opposite to the opening 31. Multiple labels 200 are stacked from bottom to top in the accommodating cavity and are located between the label pushing assembly 33 and the opening 31. The label pushing assembly 33 is used to push the labels 200 in the accommodating cavity layer by layer to the opening 31, so as to facilitate the suction cup assembly 6 to absorb the top label 200 from the opening 31.

[0031] Each suction cup assembly 6 includes a suction cup 61 and a suction cup cylinder 62. The suction cup cylinder 62 is connected to the corresponding rotating shaft 5. The suction cup 61 is installed on the suction cup cylinder 62. Each suction cup 61 has a contact surface that can contact the label 200. The contact surface is always parallel to the axis of the corresponding rotating shaft 5. The contact surface is provided with at least one air hole connected to the suction cup cylinder 62. When the suction cup assembly 6 of the pasting module 30 moves to the top of the label library group 20, a pair of rotating shafts 5 rotates so that the contact surfaces of the suction cup assemblies 6 thereon are all facing downward, and the lifting bracket 42 moves downward, so that each suction cup 61 extends from the corresponding opening 31 into the accommodating cavity and contacts the topmost label 200, and the suction cup cylinder 62 sucks the air between the suction cup 61 and the label 200 through the air hole, so that the label 200 is adsorbed on the suction cup 61. When the label 200 is moved to the area to be pasted in the mold, the suction cup cylinder 62 stops applying negative pressure to the air hole, so that the label 200 is separated from the suction cup 61 and covers the area to be pasted.

[0032] A synchronization component 7 is provided between the pair of rotating shafts 5 and the lifting bracket 42 . The synchronization component 7 is used to drive the pair of rotating shafts 5 to maintain synchronous relative movement in the left and right directions, that is, to move closer to and farther away from each other in a left-right symmetrical manner.

[0033] The synchronization assembly 7 includes a servo motor 71 mounted on the lifting bracket 42, a pair of synchronous pulleys 72 arranged opposite each other on the left and right sides, a synchronous belt 73 stretched between the pair of synchronous pulleys 72, and a pair of belt clamping blocks 74 clamped on the synchronous belt 73. The servo motor 71 is connected to one of the synchronous pulleys 72 via another pulley transmission structure, thereby driving the synchronous pulley 72 to rotate about its own axis, and the axis of the synchronous pulley 72 extends in the vertical direction. One of the belt clamping blocks 74 clamps the synchronous belt 73 on the front side of the pair of synchronous pulleys 72 and is connected to one of the rotating shafts 5. The other belt clamping block 74 clamps the synchronous belt 73 on the rear side of the pair of synchronous pulleys 72 and is connected to the other rotating shaft 5. When the servo motor 71 drives the synchronous pulleys 72, the pair of belt clamping blocks 74 move relative to each other in the left and right directions.

[0034] A sliding assembly 8 is connected between each rotating shaft 5 and the lifting bracket 42. The sliding assembly 8 includes a sliding guide rail 81 installed on the lifting bracket 42 and a sliding bracket 82 supporting the corresponding rotating shaft 5. The sliding guide rail 81 extends in the left-right direction, and the sliding bracket 82 slides with the sliding guide rail 81. The sliding assembly 8 enables a pair of rotating shafts 5 to be installed on the movable bracket 42 so that they can rotate around their own axis and move in the left-right direction.

[0035] A flip cylinder 9 is connected between each rotating shaft 5 and the corresponding sliding bracket 82. Each flip cylinder 9 is used to drive the connected rotating shaft 5 to rotate around its own axis, so that the contact surface of the suction cup 61 changes the circumferential angle of the rotating shaft 5, so that the suction cup assembly 6 can adsorb the label 200 and carry the label into the mold cavity of the mold.

[0036] The working principle of the present application is as follows: the pasting module 30 moves backward along the first guide rail 2 to move out of the accommodating space. When the suction cup assembly 6 of the pasting module 30 corresponds to a pair of label libraries 3 in the up and down directions, the synchronization assembly 7 drives the pair of rotating shafts 5 to move away from each other, so that the suction cup assembly 6 is located directly above the corresponding label library 3. The flipping cylinder 9 drives each rotating shaft 5 to rotate so that the contact surface of the suction cup assembly 6 faces downward to the label 200 in the corresponding label library 3, and the suction cup cylinder 62 works to complete the label suction operation. After the label suction is completed, the flipping cylinder 9 drives the pair of rotating shafts 5 to rotate and reset, and the synchronization assembly 7 drives the pair of rotating shafts 5 to move closer to each other to close. The pasting module 30 continues to move backward so that the suction cup assembly 6 with the label 200 adsorbed extends into the mold cavity of the mold. The pair of rotating shafts 5 open to press the label on the mold, and the suction cup cylinder 62 stops working to separate from the label. A pair of rotating shafts 5 are closed again and withdrawn from the mold to above the label magazine 3, and the label is sucked again and sent into the mold. During the continuous labeling process, the suction cup assembly 6 moves back and forth between the label magazine group 20 and the mold. After the labeling is completed, the entire pasting mold 30 returns to the accommodating space of the machine body 10 to wait for the next continuous labeling operation.

[0037] The die-forward labeling device of the present application has a simple structure, stable performance and is easy to maintain.
