[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of them.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiment 1: Please see attached Figure 1 ~Attached Figure 2 The labeling device of the present invention includes a fixing seat 1, a label conveying mechanism 2, a label suction mechanism 3 and a guide plate 4.

[0026] Among them, see Figure 1 , Figure 1 The structural relationship among the fixing base 1, the label conveying mechanism 2, the label suction mechanism 3 and the guide plate 4 in the embodiment of the present invention is shown in FIG. Figure 1 As shown, an XYZ coordinate axis is defined, wherein the first direction is parallel to the X axis, and the second direction is parallel to the Z axis, and the two directions are orthogonal to each other. It can be understood that the first direction and the second direction may not be orthogonal to each other.

[0027] Specifically, the fixed seat 1 includes a label delivery station 11 and a labeling station 12; the label conveying mechanism 2 is arranged at the label delivery station 11; the label suction mechanism 3 is arranged downstream of the label conveying mechanism 2, and the label suction mechanism 3 includes a transfer component 31 and a suction cup component 32, the transfer component 31 drives the suction cup component 32 to slide between the label delivery station 11 and the labeling station 12 along a first direction, and the suction cup component 32 is slidably connected to the transfer component 31 along a second direction, and the second direction is perpendicular to the first direction; the guide plate 4 is arranged on the moving path of the suction cup component 32 along the first direction, and the suction cup component 32 continuously abuts against the guide plate 4. Among them, the guide plate 4 includes a first guide surface 41 and a second guide surface 42 connected in sequence, the distance between the second guide surface 42 and the label delivery station 11 in the second direction is greater than the distance between the first guide surface 41 and the label delivery station 11 in the second direction, and the suction cup assembly 32 abuts against the first guide surface 41 when it is located at the label delivery station 11, and abuts against the second guide surface 42 when it is located at the labeling station 12 to avoid the label conveying mechanism 2.

[0028] In this embodiment, the transfer component 31 is used to drive the suction cup component 32 to slide along the first direction, and the suction cup component 32 can be slidably connected to the transfer component 31 along the second direction. The suction cup component 32 is used to absorb the label paper of the label conveying mechanism 2, and slide between the label delivery station 11 and the labeling station 12 under the drive of the transfer component 31, so that the suction cup component 32 absorbs the label paper in the label delivery station 11 and then continues to slide to the labeling station 12, so that the suction cup component 32 can stick the label paper to the object to be labeled.

[0029] Specifically, the guide plate 4 is arranged on the moving path of the suction cup assembly 32 along the first direction, the first guide surface 41 of the guide plate 4 corresponds to the label delivery station 11, and the second guide surface 42 corresponds to the labeling station 12. The suction cup assembly 32 continuously abuts against the guide plate 4 during the process of sucking label paper, conveying label paper and pasting label paper. Since the distance between the second guide surface 42 and the label delivery station 11 in the second direction is greater than the distance between the first guide surface 41 and the label delivery station 11 in the second direction, the suction cup assembly 32 enters the labeling station 12 after taking the label paper in the label delivery station 11, and the suction cup assembly 32 abuts against the second guide surface 42, thereby avoiding the label conveying mechanism 2, thereby avoiding the problem of interference between the suction cup assembly 32 and the label conveying mechanism 2.

[0030] It can be understood that the suction cup assembly 32 can be slidably connected to the transfer assembly 31 along the second direction, and the side of the suction cup assembly 32 close to the guide plate 4 is continuously abutted against the guide plate 4. The distance between the second guide surface 42 and the label delivery station 11 in the second direction is greater than the distance between the first guide surface 41 and the label delivery station 11 in the second direction, that is, the second guide surface 42 and the first guide surface 41 are not in the same horizontal plane, and the transfer assembly 31 drives the suction cup assembly 32 to slide between the label delivery station 11 and the labeling station 12. When the suction cup assembly 32 moves to the labeling station 12, the suction cup assembly 32 slides relative to the transfer assembly 31 along the second direction, so that the suction cup assembly 32 abuts against the second guide surface 42, thereby Avoid the label conveying mechanism 2 and label the object to be labeled. After completing the labeling action, the transfer component 31 continues to drive the suction cup component 32 to move along the first direction. When the suction cup component 32 enters the label feeding station 11 from the labeling station 12, the suction cup component 32 slides relative to the transfer component 31 along the second direction, so that the suction cup component 32 abuts against the first guide surface 41. The transfer component 31 continues to drive the suction cup component 32 to slide so as to absorb the label and label it. In this way, the label removal and labeling actions can be completed through one driving mechanism, while avoiding interference between the suction cup component 32 and the label conveying mechanism 2. Compared with the prior art, the overall structure is simpler and more reliable.

[0031] In the above-mentioned labeling device, the transfer component 31 drives the suction cup component 32 to slide along the first direction, and the suction cup component 32 is connected to the transfer component 31 by sliding along the second direction. The guide plate 4 is arranged on the moving path of the suction cup component 32 along the first direction. The suction cup component 32 continuously abuts against the guide plate 4 and avoids the label conveying mechanism 2 through the second guide surface 42 of the guide plate 4. By setting a driving mechanism to cooperate with the guide plate 4, the interference between the suction cup component 32 and the label conveying mechanism 2 can be avoided while completing the label picking and performing the labeling action, and there is no need to set up an additional control system to control the positioning accuracy of the suction cup component 32, which makes the structure simpler and more reliable while reducing the occupied space of the overall device.

[0032] In some preferred embodiments, see Figure 2 , Figure 2 The structural relationship among the first guide surface 41, the second guide surface 42 and the third guide surface 43 in the embodiment of the present invention is illustrated. The guide plate 4 further includes the third guide surface 43, the second guide surface 42 is parallel to the first guide surface 41, and the third guide surface 43 is connected to the first guide surface 41 and the second guide surface 42 respectively. The first guide surface 41 and the second guide surface 42 are arranged parallel to each other, and the third guide surface 43 is arranged obliquely between the first guide surface 41 and the second guide surface 42, so that the suction cup assembly 32 can smoothly move from abutting on the first guide surface 41 to abutting on the second guide surface 42, thereby ensuring the reliability of the guide plate 4.

[0033] Embodiment 2: The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the labeling device of the present invention. Figure 2 ~Attached Figure 4 .

[0034] Among them, see Figure 2 , Figure 2 The diagram shows the structural relationship among the first elastic member 33, the transfer assembly 31 and the suction cup assembly 32 in the embodiment of the present invention. The label suction mechanism 3 further includes a first elastic member 33 arranged along the second direction, and the two ends of the first elastic member 33 are respectively connected to the transfer assembly 31 and the suction cup assembly 32, and the suction cup assembly 32 is continuously in contact with the guide plate 4 through the first elastic member 33.

[0035] In this embodiment, the first end of the first elastic member 33 is connected to the transfer assembly 31, and the second end is connected to the suction cup assembly 32, so that the suction cup assembly 32 is continuously in contact with the guide plate 4 under the action of the first elastic member 33. Specifically, when the suction cup assembly 32 slides from the first guide surface 41 into the second guide surface 42, the suction cup assembly 32 slides along the second direction relative to the transfer assembly 31 under the action of the first elastic member 33, so that the suction cup assembly 32 is in contact with the second guide surface 42; when the suction cup assembly 32 slides from the second guide surface 42 into the first guide surface 41, the suction cup assembly 32 slides along the second direction relative to the transfer assembly 31 under the action of the first elastic member 33, so that the suction cup assembly 32 is in contact with the first guide surface 41. Preferably, the first elastic member 33 may be a tension spring.

[0036] It should be noted that a tension spring is used as the power to make the suction cup assembly 32 slide along the second direction. Compared with the device in the prior art that needs to be additionally equipped with a servo motor as a power source, the labeling device of the present invention does not require additional electrical or pneumatic assistance, and the two beats of the suction cup assembly 32 sliding along the first direction and sliding along the second direction are combined into one action, thereby effectively improving the labeling efficiency.

[0037] For further information, see Figure 3 , Figure 3 The diagram shows the structural relationship between the stopper 324 and the transfer assembly 31 in the embodiment of the present invention. The stopper 324 is provided on the side of the suction cup assembly 32 away from the guide plate 4, and the stopper 324 can abut against the transfer assembly 31, thereby limiting the sliding stroke of the suction cup assembly 32 when it slides under the action of the first elastic member 33, preventing the suction cup assembly 32 from exiting the labeling station 12 when it is separated from the guide plate 4, ensuring the position accuracy of the suction cup assembly 32, and further ensuring that the suction cup assembly 32 can accurately absorb the label paper.

[0038] In some preferred embodiments, the suction cup assembly 32 includes a label suction plate 321 and a guide wheel 322. The label suction plate 321 is slidably connected to the transfer assembly 31. A mounting portion 3211 is provided on the label suction plate 321. The guide wheel 322 is rotatably connected to the mounting portion 3211 and abuts against the guide plate 4. The end of the first elastic member 33 is connected to the mounting portion 3211. The guide wheel 322 is rotatably connected to the mounting portion 3211. Under the action of the first elastic member 33, the label suction plate 321 slides along the second direction toward the side away from the label conveying mechanism 2, thereby causing the guide wheel 322 to abut against the guide plate 4.

[0039] In some preferred embodiments, the number of the first elastic members 33 is not less than two, and the two first elastic members 33 are arranged at intervals. The two first elastic members 33 are arranged oppositely on a side of the transfer assembly 31 close to the label suction plate 321, and are respectively connected to two sides of a side of the label suction plate 321 close to the transfer assembly 31, so that the label suction plate 321 slides more smoothly when it is subjected to the force of the first elastic members 33, thereby ensuring the stability of the label suction plate 321 when sliding, and making the overall structure more reliable.

[0040] In some preferred embodiments, the label suction mechanism 3 further includes a slider 34 and a slide rail 35, wherein the slider 34 is connected to the transfer assembly 31, the slide rail 35 is connected to the label suction plate 321 and is located between the two first elastic members 33, and the slide rail 35 is slidably connected to the slider 34; and / or the slider 34 is connected to the label suction plate 321 and is located between the two first elastic members 33, the slide rail 35 is connected to the transfer assembly 31, and the slider 34 is slidably connected to the slide rail 35. The slider 34 is slidably connected to the slide rail 35, so that the label suction plate 321 slides more smoothly and stably relative to the transfer assembly 31, and avoids the label suction plate 321 from getting stuck during the sliding process, thereby preventing the label suction plate 321 from interfering with the label conveying mechanism 2.

[0041] In some preferred embodiments, the suction cup assembly 32 further includes an elastic abutment 323, a suction hole 3212 is provided on the label suction plate 321, the elastic abutment 323 is connected to the side of the label suction plate 321 away from the transfer assembly 31, and a connecting hole 3231 is provided to communicate with the suction hole 3212. The elastic abutment 323 is located between the label suction plate 321 and the label paper, and the elastic abutment 323 plays a buffering role, so that the label suction plate 321 can stick the label paper more firmly on the object to be stuck when sticking the label paper.

[0042] In some preferred embodiments, see Figure 4 , Figure 4 The structural relationship among the transfer seat 311, the guide post 312, the connecting plate 313 and the transfer driving member 314 in the embodiment of the present invention is illustrated. The transfer assembly 31 comprises the transfer seat 311, the guide post 312, the connecting plate 313 and the transfer driving member 314. The transfer seat 311 is slidably connected to the fixed seat 1. The first end of the guide post 312 is connected to the transfer seat 311. The connecting plate 313 is connected to the second end of the guide post 312. The suction cup assembly 32 is connected to the side of the connecting plate 313 facing away from the guide post 312. The transfer driving member 314 drives the transfer seat 311 to move. The guide post 312 is connected to the transfer seat 311 and the connecting plate 313 respectively. The transfer driving member 314 drives the transfer seat 311 to slide along the fixed seat 1, thereby driving the connecting plate 313 to slide along the first direction, and then driving the suction cup assembly 32 to slide along the first direction, thereby ensuring the reliability of the overall structure.

[0043] In some more preferred embodiments, the transfer assembly 31 further includes a second elastic member 315, which is sleeved on the guide post 312, and whose two ends respectively abut against the transfer seat 311 and the connecting plate 313. The second elastic member 315 plays a deceleration and buffering role, thereby avoiding the problem of the suction cup assembly 32 crushing the labeled object when labeling.

[0044] Embodiment 3: The difference between this embodiment and embodiment 2 is that this embodiment further optimizes the structure of the labeling device of the present invention. Figure 5 .

[0045] The label conveying mechanism 2 further includes an unwinding assembly 21 , a peeling sheet 22 and a rewinding assembly 23 . The unwinding assembly 21 is arranged upstream of the peeling sheet 22 , and the rewinding assembly 23 is arranged downstream of the peeling sheet 22 .

[0046] In this embodiment, the unwinding assembly 21 is used to release the material tape, the rewinding assembly 23 is used to collect the waste material tape, and the peeling sheet 22 is used to peel the label paper from the material tape. The peeling sheet 22 is arranged corresponding to the connection between the first guide surface 41 and the third guide surface 43, so that after the suction cup assembly 32 absorbs the label paper, it abuts against the second guide surface 42 through the third guide surface 43, thereby avoiding the label conveying mechanism 2.

[0047] In some preferred embodiments, the labeling device further includes an air blowing mechanism 5, which is disposed at the end of the stroke of the suction cup assembly 32 sliding along the first direction, and the air outlet of the air blowing mechanism 5 is disposed toward the suction cup assembly 32. The air blowing mechanism 5 is used to blow the label paper flat, thereby avoiding the problem that the label paper just peeled off is bent and the suction cup assembly 32 cannot be sucked. Preferably, the air blowing mechanism 5 can be a fan.

[0048] In the labeling device of the present invention, the transfer component 31 drives the suction cup component 32 to slide along the first direction, and the suction cup component 32 is connected to the transfer component 31 by sliding along the second direction. The guide plate 4 is arranged on the moving path of the suction cup component 32 along the first direction. The suction cup component 32 continuously abuts against the guide plate 4 and avoids the label conveying mechanism 2 through the second guide surface 42 of the guide plate 4. By setting a driving mechanism to cooperate with the guide plate 4, interference between the suction cup component 32 and the label conveying mechanism 2 can be avoided while completing the label picking and performing the labeling action, and there is no need to set up an additional control system to control the positioning accuracy of the suction cup component 32, which makes the structure simpler and more reliable while reducing the occupied space of the overall device.
