Description

Technical Field

[0001] This invention relates to the field of label equipment technology, and more specifically, to a label peeling mechanism and a label applying device. Background Technology

[0002] In modern industrial production, labels are ubiquitous. Whether for product identification, tracking, or advertising, precise labeling is indispensable. Labels typically consist of a backing paper and a label body bonded together with self-adhesive. Depending on the application and characteristics of the label, labels can be categorized into sheet and roll forms. Roll labels, due to their continuity and ease of automation, are widely used in automated production lines. During application, the label must first be peeled from the backing paper before being accurately pasted into the designated position. While existing labeling devices can peel the label, the process of slowly tearing it from the backing paper by the label-picking mechanism can lead to some misalignment. This can result in the label being misaligned when subsequently pasted into the desired position, making it difficult to guarantee labeling accuracy. Summary of the Invention

[0003] The main objective of this invention is to provide a label peeling mechanism and a labeling device that can solve the problem that although the existing labeling devices can peel off the label, the label may shift during the peeling process as it is slowly torn off the backing paper by the label picking mechanism, making it difficult to ensure labeling accuracy.

[0017] Furthermore, the first drive structure includes a drive motor and a synchronous belt. A synchronous pulley is provided at the end of the first shaft near the drive motor, and a pulley is provided at the end of the second shaft near the drive motor. The synchronous belt is wound around the outer periphery of the output shaft of the drive motor, the synchronous pulley, and the pulley.

[0018] Furthermore, the conveying unit also includes a clamping structure, which includes a fourth mounting bracket, a clamping assembly, and an adjusting structure. The fourth mounting bracket is mounted on the second mounting base, the clamping assembly includes a fifth mounting bracket and a clamping wheel, the adjusting structure is movably mounted on the fourth mounting bracket along the radial direction of the clamping wheel, the clamping wheel is rotatably mounted on the fifth mounting bracket, the clamping wheel is correspondingly mounted to the first rotating shaft, and the fifth mounting bracket is connected to the adjusting structure.

[0019] Furthermore, the labeling device also includes a feeding mechanism, which is mounted on the second mounting base. The feeding mechanism includes a third rotating shaft, a first stop, a second stop, and a positioning roller. The first stop and the second stop are spaced apart on the third rotating shaft along its length extension direction.

[0020] Furthermore, a second protruding structure is provided on the third rotating shaft. The second protruding structure is located between the first stop and the second stop, and extends along the length of the third rotating shaft. The second protruding structure and the first stop form a stop limit.

[0021] Furthermore, the feeding mechanism also includes a locking structure, which includes a fixed seat and a rotating member. The fixed seat is connected to the second stop member. The fixed seat is provided with a third through hole for the third rotating shaft to pass through. The rotating member is rotatably mounted on the fixed seat. The rotating member has a first rotating position and a second rotating position. When the rotating member is in the first rotating position, the rotating member abuts against the outer wall surface of the third rotating shaft. When the rotating member is in the second rotating position, there is a gap between the rotating member and the outer wall surface of the third rotating shaft.

[0022] Furthermore, the locking structure also includes an elastic element and a connecting element. The fixed seat is also provided with a mounting groove. The elastic element is installed in the mounting groove. The end of the elastic element away from the third rotating shaft is connected to the first end of the rotating element.

The adsorption structure is mounted on the fourth mounting seat and is configured to adsorb the label to be peeled.

[0024] The present invention comprises a driving unit, a peeling unit, and a guiding unit. The guiding unit is located on the recycling path of the label backing paper, and the label backing paper portion after the label has been peeled off is wrapped around the guiding unit. During the peeling operation, the label picking mechanism moves to the position of the label to be peeled off and fixes the label to be peeled off by means of adsorption or a picking pad with a certain degree of adhesion. Then, the driving unit drives the peeling unit to move in a first direction toward the driving unit. Since the guiding unit and the peeling unit move synchronously, they pull the label backing paper, thereby separating the label from the label backing paper. During the label peeling process, the position of the label to be peeled off does not change; only the peeling unit, the guiding unit, and the label backing paper are displaced. Compared with the prior art labeling devices where the label is slowly peeled off from the backing paper by the label picking mechanism during the label picking process, the position of the label in this application does not change during the peeling process, which can effectively prevent the label from shifting during the peeling process and thus significantly improve the labeling accuracy.

[0044] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0045] See also Figures 1 to 13 As shown, the present invention provides a label peeling mechanism, which includes: a driving part 21; a peeling part 22, the peeling part 22 being located on the conveying path of the label 30 to be peeled, one end of the driving part 21 being drivenly connected to the peeling part 22 to drive the peeling part 22 to move along a first direction, the peeling part 22 having a bearing surface for bearing the label 30 to be peeled; and a guide part 23, the guide part 23 being located on the recycling path of the label backing paper, a portion of the label backing paper being wound around the guide part 23, the guide part 23 being configured to move synchronously with the peeling part 22.

[0046] In this embodiment, the first direction refers to the conveying direction of the label 30 to be peeled off at the location of the bearing surface. The peeling part 22 is located on the conveying path of the label 30 to be peeled off. The portion of the label 30 to be peeled off that is conveyed to the location of the peeling part 22 is supported by the bearing surface. The guide part 23 is located on the recycling path of the label backing paper. The label backing paper portion after the label has been peeled off is wrapped around the guide part 23 and guided by the guide part 23 to the location of the subsequent label backing paper recycling device. Figure 4 As shown, the label is in an unpeeled state. At this time, the label to be peeled 30 is stationary and does not move, that is, the label to be peeled 30 is relatively stationary with respect to the bearing surface. When the peeling operation is performed, the label picking mechanism 70 moves to the position of the label to be peeled 30 and fixes the label to be peeled 30 by adsorption or a picking pad with a certain degree of adhesion. Then, the driving part 21 drives the peeling part 22 to move in the first direction toward the driving part 21. Since the guide part 23 and the peeling part 22 move synchronously, they pull the label backing paper, realizing the separation of the label from the label backing paper. As can be seen from the above, the position of the label to be peeled 30 does not change during the label peeling process. The parts that are displaced are the peeling part 22, the guide part 23, and the label backing paper. Compared with the labeling device of the prior art, in the process of picking the label, the label is slowly peeled off from the backing paper by the label picking mechanism 70. The position of the label in this application does not change during the peeling process, which can effectively prevent the label from shifting during the peeling process, thereby significantly improving the labeling accuracy.

[0047] In one embodiment of the present invention, the driving part 21 is driven to connect with the guide part 23 so as to drive the guide part 23 to move synchronously with the peeling part 22 along the first direction.

[0048] In this embodiment, both the guide part 23 and the stripping part 22 are driven and connected to the drive part 21, and under the drive of the drive part 21, the two can achieve synchronous movement. This arrangement can simplify the control logic of the device, reduce the control requirements of multiple independent moving parts, and reduce the design complexity and cost of the control system.

[0049] In one embodiment, the drive unit 21 can be a double-acting cylinder, with the piston rod extending from both ends of the cylinder. When moving, one end of the piston rod gradually moves away from the center of the cylinder, while the other end gradually moves closer to the center of the cylinder. Alternatively, the drive unit 21 can also include two electric push rods and a synchronization controller. One electric push rod is used to drive the peeling part 22, and the other electric push rod is used to drive the guide part 23. The two electric push rods move synchronously through the synchronization controller, thereby enabling the peeling part 22 and the guide part 23 to move synchronously.

[0050] See also Figures 1 to 13 As shown, in one embodiment of the present invention, along a first direction, the driving part 21 has a first end and a second end disposed opposite to each other, the peeling part 22 is disposed at the first end of the driving part 21 and is drivenly connected to the first end of the driving part 21, and the guide part 23 is disposed at the second end of the driving part 21 and is drivenly connected to the second end of the driving part 21.

[0051] In this embodiment, the guide portion 23 and the stripping portion 22 are arranged on opposite sides of the drive portion 21 along the first direction and are both driven by the drive portion 21. This arrangement simplifies the control logic of the device, reduces the control requirements for multiple independent moving parts, and lowers the design complexity and cost of the control system.

[0052] See also Figures 1 to 13 As shown, in one embodiment of the present invention, the driving part 21 includes a driving body 211 and a first telescopic structure 212. The first telescopic structure 212 is movably disposed on the driving body 211 along a first direction. The peeling part 22 includes a first mounting base 221 and a limiting structure 222. The first mounting base 221 is connected to the end of the first telescopic structure 212 away from the guide part 23. A support platform 223 is disposed on the first mounting base 221. A bearing surface is formed on the side of the support platform 223 away from the first mounting base 221. The limiting structure 222 is movably disposed on the support platform 223 along a second direction.

[0053] In this embodiment, the first telescopic structure 212 is movably disposed on the drive body 211 along the first direction. Since the first mounting base 221 is connected to the end of the first telescopic structure 212 away from the guide portion 23, the first mounting base 221 can move along the first direction. Since the support platform 223 is disposed on the first mounting base 221, the support platform 223 can also move along the first direction. Along the second direction, the support platform 223 has a first side and a second side disposed opposite to each other. A limiting baffle 82 is disposed on the first side of the support platform 223, and a limiting structure 222 is disposed on the second side of the support platform 223. The limiting structure 222 and the limiting baffle 82 are disposed correspondingly, and the two cooperate to limit the label 30 to be peeled in the second direction. Since the limiting structure 222 can move relative to the support platform 223 along the second direction, it can adapt to labels 30 of different sizes to be peeled, thereby improving applicability.

[0054] See also Figures 1 to 13 As shown, in one embodiment of the present invention, a first protrusion structure 224 is provided on one of the limiting structure 222 and the bearing platform 223, and a groove 225 is provided on the other of the limiting structure 222 and the bearing platform 223. The first protrusion structure 224 is adapted to the groove 225, and the first protrusion structure 224 is slidably disposed in the groove 225 along the second direction.

[0055] In this embodiment, the first protrusion structure 224 is slidably disposed in the groove 225 along the second direction. On the one hand, it can realize the sliding connection between the limiting structure 222 and the support platform 223. On the other hand, it can realize the sliding guidance. The first protrusion structure 224 is adapted to the groove 225, which can avoid unnecessary shaking of the limiting structure 222 during the sliding process and ensure the stability during the sliding process.

[0056] In one embodiment, the groove 225 is a dovetail groove, and the first protrusion structure 224 is a dovetail-shaped protrusion adapted to the dovetail groove.

[0057] In one embodiment, the groove 225 is a T-groove, and the first protrusion structure 224 is a T-shaped protrusion adapted to the T-groove.

[0058] See also Figures 1 to 13 As shown, in one embodiment of the present invention, the peeling part 22 further includes an auxiliary guide structure 226. The auxiliary guide structure 226 includes a first guide roller 2261 and a second guide roller 2262. The first guide roller 2261 is located between the guide part 23 and the second guide roller 2262. The first guide roller 2261 is installed at the bottom of the first mounting base 221. The second guide roller 2262 is disposed on the side of the support platform 223 near the first mounting base 221. The second guide roller 2262 and the end of the support platform 223 away from the guide part 23 form a material passage gap.

[0059] In this embodiment, the first guide roller 2261 guides and supports the label backing paper. The second guide roller 2262 and the far end of the support platform 223 form a material passage 413. After the label is peeled off, the label backing paper passes through the material passage 413 and reaches the position of the first guide roller 2261. The first guide roller 2261 supports and guides the label backing paper, ensuring that the label backing paper can smoothly reach the guide section 23. Through the cooperation of the first guide roller 2261 and the second guide roller 2262, a continuous guide path is formed, ensuring that the label backing paper can smoothly reach the guide section 23.

[0060] In one embodiment, the peeling section 22 further includes a third mounting base 227, which is connected to the first mounting base 221, and the second guide roller 2262 is mounted on the third mounting base 227.

[0061] See also Figures 1 to 13 As shown, in one embodiment of the present invention, the side of the support platform 223 away from the drive unit 21 has a tip, and the second guide roller 2262 forms a material passage gap with the side of the tip facing the first mounting base 221.

[0062] In this embodiment, the label backing paper at the location of the label to be peeled off 30 is located on the side of the tip away from the first mounting base 221, while the label backing paper with the label already peeled off is located on the side of the tip close to the first mounting base 221. Supported by the tip, the label backing paper forms a sharp angle. The edge of the tip away from the drive unit 21 serves as the starting point for the separation of the label and label backing paper. The drive unit 21 drives the peeling unit 22 and the guide unit 23 to move synchronously in a first direction away from the tip, pulling the label backing paper. This causes the label and label backing paper to begin separating at the edge of the tip. The design of the tip allows this separation process to proceed along a preset, precise starting point, ensuring the accuracy of label peeling. The label backing paper with the label already peeled off passes through the material feeding gap to the side of the tip close to the first mounting base 221, and then is guided to the conveying and recycling mechanism 50 via the first guide roller 2261 and the guide unit 23.

[0063] See also Figures 1 to 13 As shown, in one embodiment of the present invention, the guide portion 23 includes a first mounting bracket 231 and a first guide wheel 232, and the drive portion 21 further includes a second telescopic structure 213. The second telescopic structure 213 is movably disposed on the drive body 211 along a first direction. One end of the second telescopic structure 213 away from the peeling portion 22 is connected to the first mounting bracket 231. The first guide wheel 232 is mounted on the first mounting bracket 231 and can rotate relative to the first mounting bracket 231 along its own central axis.

[0064] In this embodiment, the second telescopic structure 213 is movably disposed on the driving body 211 along the first direction. Since the end of the second telescopic structure 213 away from the peeling part 22 is connected to the first mounting frame 231, it can drive the first mounting frame 231 to move along the first direction. The first guide wheel 232 is mounted on the first mounting frame 231, and thus can drive the first guide wheel 232 to move along the first direction.

[0065] According to another aspect of the present invention, a labeling device is provided, comprising: a second mounting base 10; and a label peeling mechanism 20 as described above, the label peeling mechanism 20 being mounted on the second mounting base 10.

[0066] In this embodiment, the label peeling mechanism 20 of the labeling device has all the technical solutions and effects of the label peeling mechanism 20 described above, which will not be repeated here.

[0067] See also Figures 1 to 13 As shown, in one embodiment of the present invention, the labeling device further includes a positioning mechanism 40, which is mounted on the second mounting base 10. The positioning mechanism 40 includes an identification part 41 and a clamping structure 42. Both the identification part 41 and the clamping structure 42 are located on the conveying path of the label to be peeled 30. The identification part 41 is disposed on the feeding side of the clamping structure 42. The identification part 41 is configured to identify the positioning marks of a group of labels to be peeled 30. The group of labels to be peeled 30 includes at least one label to be peeled 30. The at least one label to be peeled 30 is provided with a positioning mark. The clamping structure 42 is used to clamp the label to be peeled 30.

[0068] In this embodiment, the identification unit 41 can identify a set of positioning marks on the labels 30 to be peeled, thereby positioning the labels 30. The positioning marks can be pre-printed on the labels, such as barcodes, QR codes, or specific shapes and colors, or they can be inherent features on the labels, such as through holes. The clamping structure 42 stably clamps the labels 30 after the identification unit 41 completes the positioning, thus pausing the feeding of the labels 30. Through the above settings, the output length of the labels 30 can be precisely controlled. After the feeding is in place, the clamping structure 42 clamps the labels 30, and the feeding process ends.

[0069] See also Figures 1 to 13 As shown, in one embodiment of the present invention, the identification unit 41 includes a main structure 411 and a sensing device 412 disposed on the main structure 411. The main structure 411 has a material passage 413 through which the label 30 to be peeled can pass. The sensing device 412 is disposed toward the label 30 to be peeled.

[0070] In this embodiment, the sensing device 412 on the main structure 411 is positioned towards the label 30 to be peeled off, so as to identify the positioning mark on the label 30 to be peeled off and accurately control the discharge length. The material passage 413 provides a conveying path for the label 30 to be peeled off.

[0071] In one embodiment, the sensing device 412 employs a fiber optic through-beam sensor. The clamping structure 42 includes a third driving structure 421, a first clamping plate 422, and a second clamping plate 423. The first clamping plate 422 is fixedly connected to the second mounting base 10, and the second clamping plate 423 is drivenly connected to the third driving structure 421. The third driving structure 421 can drive the second clamping plate 423 to move closer to or further away from the first clamping plate 422 to clamp or release the label 30 to be peeled off. The third driving structure 421 is communicatively connected to the fiber optic through-beam sensor.

[0072] The fiber optic through-beam sensor includes a transmitter and a receiver. The transmitter generates and emits a light beam. When the light beam travels directly and unobstructed from the transmitter to the receiver, the receiver generates a signal indicating that the beam path is continuous. The transmitter and the sensor are respectively positioned on opposite sides of the feed channel 413. When the label to be peeled 30 enters the feed channel 413, the label to be peeled 30 is located between the transmitter and the sensor. The positioning mark on the label to be peeled 30 is a through hole 31. When the label to be peeled 30 with the through hole 31 moves into the beam path of the fiber optic through-beam sensor, the light beam passes through the through hole 31 and continues to be received by the receiver. At this time, the fiber optic through-beam sensor generates a control signal, causing the third drive structure 421 to drive the second clamping plate 423 to move closer to the first clamping plate 422 until it clamps the label to be peeled 30.

[0073] In one embodiment, the third drive structure 421 may be a cylinder or an electric motor.

[0074] In one embodiment, the sensing device 412 employs a prior art visual recognition device to capture an image of the tag 30 to be peeled off, which includes a positioning identifier, to achieve positioning.

[0076] In this embodiment, during installation, the bolt passes through the first slot 4141 and connects to the second mounting base 10 to connect the second mounting bracket 414 and the second mounting base 10 together. Since the first slot 4141 extends vertically, the position of the identification part 41 can be adjusted vertically according to the actual installation needs. The bolt passes through the second slot 4151 and connects to the third mounting bracket 415 to connect the main structure 411 and the third mounting bracket 415 together. Since the second slot 4151 extends in the second direction, the position of the main structure 411 can be changed by changing the position of the bolt in the second slot 4151.

The label backing paper is wound around the second rotating shaft 531, and the first driving structure 51 drives the second rotating shaft 531 to rotate around its own central axis to realize the recycling of the label backing paper. The first driving structure 51 can drive the first rotating shaft 521 to rotate around its own central axis.

[0079] See also Figures 1 to 13 As shown, in one embodiment of the present invention, the first drive structure 51 includes a drive motor 511 and a synchronous belt 512.

[0080] With the above configuration, the drive motor 511 can drive the synchronous pulley 522 and the belt pulley 532 to rotate. Since the synchronous pulley 522 is fixedly installed on the first rotating shaft 521 and the belt pulley 532 is fixedly installed on the second rotating shaft 531, it can drive the first rotating shaft 521 and the second rotating shaft 531 to rotate.

[0081] See also Figures 1 to 13As shown, in one embodiment of the present invention, the conveying unit 52 further includes a first bearing housing 524, a fourth bearing, and a tensioning pulley 525.

A portion of the synchronous belt 512 is wound around the outer periphery of the tensioning pulley 525 to ensure the tension of the synchronous belt 512.

[0082] See also Figures 1 to 13 As shown, in one embodiment of the present invention, the conveying unit 52 further includes a pressing structure 523. The pressing structure 523 includes a fourth mounting bracket 5231, a pressing assembly 5232, and an adjusting structure 5233. The fourth mounting bracket 5231 is mounted on the second mounting base 10. The pressing assembly 5232 includes a fifth mounting bracket 52321 and a pressing wheel 52322.

The fifth mounting bracket 52321 is connected to the adjusting structure 5233.

[0083] In this embodiment, the fifth mounting bracket 52321 is connected to the adjustment structure 5233. When the adjustment structure 5233 moves radially relative to the fourth mounting bracket 5231 along the pressure roller 52322, it can drive the fifth mounting bracket 52321 to move closer to or further away from the first rotating shaft 521. Since the pressure roller 52322 is mounted on the fifth mounting bracket 52321, the distance between the pressure roller 52322 and the first rotating shaft 521 can be adjusted. The gap between the pressure roller 52322 and the first rotating shaft 521 is used for the label backing paper to pass through.

[0084] See also Figures 1 to 13 As shown, in one embodiment of the present invention, the conveying unit 52 further includes two compression springs 5234, and the adjusting structure 5233 is a bolt. One end of the bolt is threadedly connected to the fourth mounting bracket 5231, and the other end of the bolt is threadedly connected to the fifth mounting bracket 52321. The two compression springs 5234 are spaced apart along the axial direction of the pressure wheel 52322, and the compression springs 5234 are connected between the fourth mounting bracket 5231 and the fifth mounting bracket 52321 to play a buffering role. When it is necessary to adjust the distance between the pressure wheel 52322 and the first rotating shaft 521, the bolt is rotated. At this time, the fifth mounting bracket 52321 drives the pressure wheel 52322 to move closer to or away from the first rotating direction, thereby realizing the adjustment of the distance between the two.

[0085] See also Figures 1 to 13 As shown, in one embodiment of the present invention, the labeling device further includes a feeding mechanism 60, which is mounted on the second mounting base 10. The feeding mechanism 60 includes a third rotating shaft 61, a first stop 62, a second stop 63, and a positioning roller 65.

[0086] In this embodiment, the positioning roller 65 is fixedly sleeved on the third rotating shaft 61, and the label roll is sleeved on the positioning roller 65. The rotation of the third rotating shaft 61 drives the positioning roller 65 to rotate, thereby driving the label roll to rotate. The first stop 62 and the second stop 63 are used to limit the positioning roller 65 and the label roll in the axial direction of the third rotating shaft 61.

[0087] In one embodiment, both the first stop 62 and the second stop 63 are circular plates with multiple through holes to reduce weight.

[0088] See also Figures 1 to 13 As shown, in one embodiment of the present invention, a second protrusion structure 611 is provided on the third rotating shaft 61. The second protrusion structure 611 is located between the first stop member 62 and the second stop member 63. Along the length extension direction of the third rotating shaft 61, the second protrusion structure 611 and the first stop member 62 form a stop limit.

[0089] In this embodiment, the second protrusion structure 611 can provide a stop and limit the first stop member 62 in the length extension direction of the third rotating shaft 61.

[0090] In one embodiment, the second protrusion structure 611 is an annular protrusion.

[0091] See also Figures 1 to 13 As shown, in one embodiment of the present invention, the feeding mechanism 60 further includes a locking structure 64. The locking structure 64 includes a fixed base 641 and a rotating member 642. The fixed base 641 is connected to the second stop member 63. The fixed base 641 is provided with a third through hole for the third rotating shaft 61 to pass through. The rotating member 642 is rotatably disposed on the fixed base 641. The rotating member 642 has a first rotating position and a second rotating position. When the rotating member 642 is in the first rotating position, the rotating member 642 abuts against the outer wall surface of the third rotating shaft 61. When the rotating member 642 is in the second rotating position, there is a gap between the rotating member 642 and the outer wall surface of the third rotating shaft 61.

[0092] In this embodiment, when the rotating member 642 is in the first rotating position, the rotating member 642 abuts against the outer wall surface of the third rotating shaft 61, preventing the fixed seat 641 from detaching from the third rotating shaft 61. Since the second stop member 63 is connected to the fixed seat 641, it can prevent the second stop member 63 from detaching from the third rotating shaft 61. When the rotating member 642 is in the second rotating position, there is a gap between the rotating member 642 and the outer wall surface of the third rotating shaft 61, allowing the second stop member 63 to be removed from the third rotating shaft 61.

[0093] See also Figures 1 to 13 As shown, in one embodiment of the present invention, the locking structure 64 further includes an elastic element 643 and a connecting element 644.

The connecting element 644 passes through the fixed base 641. The second end of the rotating element 642 is sleeved on the connecting element 644, and part of the rotating element 642 is located in the mounting notch. When the rotating element 642 is in the first rotating position, the second end of the rotating element 642 abuts against the outer wall surface of the third rotating shaft 61. When the rotating element 642 is in the second rotating position, the elastic element 643 is compressed.

[0094] In this embodiment, the mounting notch provides installation space for the rotating member 642. When the first end of the rotating member 642 is pressed, the elastic member 643 is compressed, and the first end of the rotating member 642 rotates towards the third rotating shaft 61. The rotating member 642 is in the second rotation position, and the second end of the rotating member 642 is lifted. At this time, the fixing seat 641 and the second stop 63 can be removed from the third rotating shaft 61. After being released, under the action of the elastic restoring force of the elastic member 643, the first end of the rotating member 642 rotates away from the third rotating shaft 61, and the second end of the rotating member 642 rotates towards the third rotating shaft 61. At this time, the rotating member 642 is in the first rotation position, and the second end of the rotating member 642 abuts against the outer wall surface of the third rotating shaft 61, which can prevent the second stop 63 and the fixing seat 641 from detaching from the third rotating shaft 61. As can be seen from the above, the label roll can be replaced by the rotating member 642, which is relatively convenient.

[0095] In one embodiment, the elastic element 643 is a compression spring.

[0096] See also Figures 1 to 13As shown, in one embodiment of the present invention, the feeding mechanism 60 further includes a fixing plate 66, a third bearing seat 67, a fixing nut 68, a friction plate 69, a washer 691, a compression spring 692, an adjusting nut 693, a fifth mounting base 694, and two first bearings 696. The third bearing seat 67 is sleeved on the third rotating shaft 61 and has a receiving cavity. The two bearings are sequentially sleeved on the third rotating shaft 61 along the length direction of the third rotating shaft 61 and are located in the receiving cavity of the third bearing seat 67. The fixing plate 66 is sleeved on the end of the third bearing seat 67 near the first stop member 62. The fixing plate 66 and the second mounting base 10. Fixed connection: A fixing nut 68 is sleeved on the third rotating shaft 61 to press the two first bearings 696 together, thereby limiting the two first bearings 696 in the axial direction of the third rotating shaft 61.

By rotating the adjusting nut 693, the compression amount of the compression spring 692 can be adjusted, the pressure of the friction plate 69 on the third bearing seat 67 can be adjusted, and thus the friction force of the third rotating shaft 61 during rotation can be adjusted.

[0097] See also Figures 10 to 12 As shown, in one embodiment of the present invention, the feeding mechanism 60 further includes a fifth mounting base 694 and an optical fiber sensor 695. The fifth mounting base 694 is fixedly connected to the fixing plate 66, and the optical fiber sensor 695 is mounted on the fifth mounting base 694.

The adsorption structure 732 is mounted on the fourth mounting seat 731 and is configured to adsorb the label 30 to be peeled off.

[0099] In this embodiment, the connecting seat 71 can be connected to a robotic arm, etc. The second driving structure 72 can drive the fourth mounting seat 731 to move in a direction close to or away from the label peeling mechanism 20. Since the adsorption structure 732 is mounted on the fourth mounting seat 731, it can drive the adsorption structure 732 to move in a direction close to or away from the label peeling mechanism 20 to remove the peeled label.

[0100] like Figure 13 As shown, in one embodiment, the adsorption structure 732 includes a suction cup 734 and an air tube connector 733. The suction cup 734 is made of a flexible material such as silicone or rubber. The shape and size of the suction cup 734 can be adjusted according to the size and shape of the label to ensure close contact with the label surface. The surface of the suction cup 734 that contacts the label is provided with air holes. The suction cup 734 is connected to a vacuum system via the air tube connector 733. The vacuum system can employ existing technology. When the vacuum system is activated, it draws air out of the suction cup 734, reducing the internal air pressure. Due to the pressure difference between the inside and outside of the suction cup 734, the external atmospheric pressure presses the label against the suction cup 734, achieving label adsorption. When it is necessary to attach the label to the product, the vacuum system stops drawing air and may even introduce air into the suction cup 734, thereby increasing the internal air pressure, eliminating the negative pressure, and separating the label from the suction cup 734.

[0101] See also Figures 1 to 13 As shown, in one embodiment of the present invention, the labeling device further includes three second guide structures 80 and three third guide structures 200 mounted on the second mounting base 10.

The roller 102 is correspondingly arranged with the support platform 223, and the roller 102 presses down on the label 30 to be peeled on the support platform 223 to prevent the label 30 to be peeled from moving up and down. After the label roll is manually installed, one end of the label 30 to be peeled is manually pulled to keep it in place. Figure 3 As shown, it is wrapped around the corresponding structure, with the starting end of the label 30 to be peeled off at... Figure 9 The first rotating shaft 521 and the second rotating shaft 531 of the recycling section 53 are wound around once, and then a U-shaped clamp is inserted to fix one end of the label 30 to be peeled to the second rotating shaft 531. The drive motor 511 is started, and the first rotating shaft 521 and the second rotating shaft 531 rotate to pull the label 30 to be peeled to achieve feeding.

[0103] See also Figures 1 to 16 As shown, in one embodiment of the present invention, the labeling device further includes two auxiliary pressing mechanisms 90.

[0105] See also Figures 1 to 13As shown, in one embodiment of the present invention, the labeling device further includes a SCARA (Selective Compliance Assembly Robot Arm), and the connecting seat 71 is connected to the selective compliant assembly robot arm 74. The selective compliant assembly robot arm 74 adopts the prior art, and its specific structure will not be described in detail here.

[0106] It should be noted that SCARA robots can also be replaced by six-axis robots or collaborative robots with higher degrees of freedom to improve the flexibility of applications.

[0107] The control flow of the labeling device in this application is as follows: The device is powered on, and the fiber optic sensor 695 detects whether the label roll material is installed correctly or exhausted. If the label material is absent or exhausted, the device pauses, and the operator replaces or adds the label roll material. If the label material is present, the process continues. The drive unit 21 drives the peeling unit 22 and the guide unit 23 to move synchronously in the first direction away from the conveying and recycling mechanism 50. Then, the third drive structure 421 drives the second clamping plate 423, causing the second clamping plate 423 to move away from the first clamping plate 422, releasing the label 30 to be peeled off. Then, the drive motor 511 starts. The second rotating shaft 531 is driven to rotate, and the positioning mark of the label 30 to be peeled is identified by the identification part 41 of the positioning mechanism 40. If the mark is identified, the third driving structure 421 drives the second clamping plate 423 to move closer to the first clamping plate 422 to clamp the label 30 to be peeled. Then, the adsorption structure 732 adsorbs the label 30 to be peeled, and the driving part 21 drives the peeling part 22 and the guide part 23 to move synchronously along the first direction towards the conveying and recycling mechanism 50 to peel off the label 30. Finally, the SCARA robot drives the label to the preset labeling position for labeling operation.

[0108] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects: A driving part, a peeling part, and a guiding part are provided. The guiding part is located on the recycling path of the label backing paper, and the label backing paper portion after the label has been peeled off is wrapped around the guiding part. During the peeling operation, the label picking mechanism moves to the position of the label to be peeled off and fixes the label to be peeled off by adsorption or a certain adhesive picking pad. Then, the driving part drives the peeling part to move in a first direction towards the driving part. Since the guiding part and the peeling part move synchronously, they move synchronously and pull the label backing paper, achieving separation of the label from the label backing paper. During the label peeling process, the position of the label to be peeled off does not change; only the peeling part, the guiding part, and the label backing paper are displaced. Compared to the prior art labeling devices where the label is slowly peeled off from the backing paper by the label picking mechanism during the label picking process, the position of the label in this application does not change during the peeling process, effectively preventing label displacement during peeling and significantly improving labeling accuracy.
