[0041] Modes for Carrying Out the Invention

[0042] FIG1 is a schematic diagram of the structure of the labeling device provided by the present embodiment at one viewing angle. FIG2 is a schematic diagram of the structure of the labeling device provided by the present embodiment at another viewing angle. FIG3 is a partial enlarged view of point A in FIG1. ​​As shown in FIG1-FIG3, the present embodiment provides a labeling device, which includes a film supply mechanism 100, a supporting mechanism 200 and a label rolling mechanism 300. The film supply mechanism 100 includes a mounting frame 110 and a tape feeding assembly and a label peeling assembly 130 both of which are arranged on the mounting frame 110. The tape feeding assembly is configured to convey a label tape 1000. The label tape 1000 includes a release paper and a label paper attached to the release paper. The label peeling assembly 130 can peel the label paper of the label tape 1000 conveyed thereto from the release paper. The supporting mechanism 200 is located on one side of the label peeling assembly 130. The part 2000 to be labeled is rotatably carried on the supporting mechanism 200. The label rolling mechanism 300 is configured to convey a label tape 1000. 00 is located above the supporting mechanism 200. The label rolling mechanism 300 includes a label rolling lifting drive 310, a label rolling rotation drive 320 connected to the output end of the label rolling lifting drive 310, and a label rolling roller 330 connected to the output end of the label rolling rotation drive 320. The label rolling lifting drive 310 can drive the label rolling roller 330 to rise and fall in the vertical direction through the label rolling rotation drive 320 to drive the peeled label paper to approach the to-be-labeled object 2000 on the supporting mechanism 200 and press the label paper onto the to-be-labeled object 2000. The label rolling rotation drive 320 can drive the label rolling roller 330 to rotate to attach the label paper to the to-be-labeled object 2000.

[0043] In this embodiment, the object 2000 to be labeled is mainly a cylindrical battery. In other embodiments, the object 2000 to be labeled can also be other cylindrical products that need to have label paper attached to their surface.

[0044] In the labeling device provided in this embodiment, during labeling, the object 2000 to be labeled is carried on the carrying mechanism 200, and the tape feeding assembly conveys the label tape 1000 to the label peeling assembly 130, which peels the label paper from the release paper. Then, the label roller lifting drive 310 drives the label roller 330 to move downward in the vertical direction via the label roller rotating drive 320, so as to bring the peeled label paper closer to the object 2000 to be labeled on the carrying mechanism 200 and press the label paper onto the object 2000 to be labeled. The label roller rotating drive 320 then drives the label roller 330 to rotate, and the object 2000 to be labeled moves with it, so that the label paper between the label roller 330 and the object 2000 to be labeled is attached to the outer surface of the object 2000 to be labeled. Through the mutual cooperation between the film supply mechanism 100, the supporting mechanism 200 and the label rolling mechanism 300, the automatic labeling operation of the label paper can be realized. Compared with the manual labeling in the related technology, it can not only improve the labeling efficiency and reduce labor costs, but also ensure the labeling quality and improve the yield rate of the finished product.

[0045] Optionally, in this embodiment, the label roller lifting drive 310 is a pneumatic cylinder, and the label roller rotation drive 320 is a first motor. In other embodiments, the label roller lifting drive 310 can also be a drive device with a linear drive function, such as an oil cylinder or an electric cylinder.

[0046] As shown in Figures 1 and 3, the label peeling assembly 130 includes a label peeling plate 131. The side of the label peeling plate 131 facing the carrier mechanism 200 is provided with a sharp corner 1311. When the tape feed assembly drives the label tape 1000 past the label peeling plate 131, the sharp corner 1311 acts to peel the label paper from the release paper. As the label tape 1000 continues to be transported, the peeled label paper continues to move between the carrier mechanism 200 and the label rolling mechanism 300. The label rolling roller 330 then moves downward to press the label paper onto the object 2000 to be labeled on the carrier mechanism 200, and rotates to adhere the label paper to the surface of the object 2000 to be labeled.

[0047] The label stripping assembly 130 also includes a stopper 132, which is positioned upstream of the label stripping plate 131. A stopper slot 1321 is provided on the side of the stopper 132 facing the label stripping plate 131, allowing the label tape 1000 to pass between the stopper slot 1321 and the label stripping plate 131. The stopper 132 with the stopper slot 1321 limits the position of the label tape 1000 as it passes through the label stripping plate 131, preventing the label tape 1000 from shifting as it passes through the label stripping plate 131 and affecting the labeling process.

[0048] The label stripping assembly 130 also includes two stoppers 133, which are positioned on either side of the label stripping plate 131 perpendicular to the direction of transport of the label tape 1000. The label tape 1000 can pass between the two stoppers 133. The two stoppers 133 provide a secondary position limit for the label tape 1000 passing through the label stripping plate 131, ensuring a high-quality fit between the label paper and the object 2000 to be labeled.

[0049] Optionally, the spacing between the two limiting baffles 133 is adjustable. This design enables the film feeding mechanism 100 to be adapted to feed label tapes 1000 of various specifications and sizes. The spacing between the two limiting baffles 133 can be adaptively adjusted according to the width of the label tape 1000, thereby improving the versatility of the labeling device. Exemplarily, at least one of the two limiting baffles 133 is movably mounted on the label stripping plate 131. The label stripping plate 131 is provided with a waist-shaped hole extending perpendicular to the transmission direction of the label tape 1000. The movable limiting baffle 133 is provided with a connecting hole. Connectors can be sequentially inserted into the waist-shaped hole and the connecting hole to secure the limiting baffle 133 to the label stripping plate 131. The connecting members are connecting bolts, and the connecting holes are threaded holes. Bolted connections have the advantages of simple structure, convenient operation, and stable connection.

[0050] Continuing with Figures 1-3, to ensure the accuracy of the transport position of the label tape 1000, the labeling device further includes a deflection correction mechanism 400, which includes a deflection correction drive assembly 410 and a deviation detection assembly 420. The deviation detection assembly 420 is configured to detect whether there is any deviation in the transport position of the label tape 1000. The output end of the deflection correction drive assembly 410 is connected to the mounting frame 110 to drive the mounting frame 110 to move in a direction perpendicular to the transport direction of the label tape 1000. Before the label tape 1000 is transported to the label stripping assembly 130, the deviation detection assembly 420 first detects the transport position of the label tape 1000. If it is detected that the label tape 1000 has deviated from the preset position, the detection result is transmitted to the transport system of the labeling device. The transport system then controls the deflection correction drive assembly 410 to activate, thereby driving the entire film supply mechanism 100 through the mounting frame 110 to move in a direction perpendicular to the transport direction of the label tape 1000, thereby adjusting the transport position of the label tape 1000.

[0051] The deflection correction drive assembly 410 includes a deflection correction bracket 411 and a deflection correction driver 412. The mounting frame 110 is slidably mounted on the deflection correction bracket 411. The deflection correction driver 412 is mounted on the deflection correction bracket 411. The output end of the deflection correction driver 412 is connected to the mounting frame 110 to drive the mounting frame 110 to move in a direction perpendicular to the transmission direction of the label tape 1000. Optionally, the deflection correction drive assembly 410 also includes a deflection correction slide 413. The deflection correction slide 413 is disposed between the deflection correction bracket 411 and the mounting frame 110. The deflection correction slide 413 includes a deflection correction rail disposed on the deflection correction bracket 411 and a deflection correction slider disposed on the mounting frame 110. The deflection correction rail extends in a direction perpendicular to the transmission direction of the label tape 1000. The deflection correction slider slidably engages with the deflection correction rail. The correction slide 413 can provide a guide for the mounting frame 110 to slide along the correction bracket 411, thereby ensuring smooth sliding and accurate position adjustment of the label tape 1000. Optionally, the correction driver 412 can be a linear drive device such as a linear motor, a pneumatic cylinder, an electric cylinder, or a motor plus a screw nut pair.

[0052] In this embodiment, the offset detection assembly 420 includes an offset detection member 421 and a detection bracket 422. The detection bracket 422 is located on one side of the mounting frame 110. The offset detection member 421 is mounted on the detection bracket 422. The offset detection member 421 can capture image information of the label tape 1000 and transmit this image information to the control system of the labeling device. The control system determines whether the transmission position of the label tape 1000 is offset by comparing the standard image information with the current image information. Optionally, the offset detection member 421 is an ultrasonic sensor.

[0053] As shown in Figures 1 and 2, the tape feed assembly includes a reel 121, a reel 122, and a reel drive unit 123. The reel 121 and reel 122 are spaced apart and rotatably mounted on the mounting frame 110. The reel 121 is configured to release the label tape 1000, and the reel 122 is configured to reel in the release paper from the peeled label paper. The reel drive unit 123 is disposed on the mounting frame 110 and is configured to drive the reel 122 to rotate, thereby driving the label tape 1000 through the label peeling assembly 130. Optionally, the reel 121 and reel 122 are both mounted on the mounting frame 110 via bearings, allowing the reel 121 and reel 122 to rotate smoothly relative to the mounting frame 110. Among them, the unwinding shaft 121 is configured to release the label tape 1000, and the reeling shaft 122 is configured to recycle the release paper of the peeled label paper. The reeling drive unit 123 can drive the reeling shaft 122 to rotate, so that after the label tape 1000 is released from the unwinding shaft 121, it passes through the label peeling component 130 to peel off the label paper, and then the release paper is recovered by the reeling shaft 122.

[0054] As shown in Figure 6, the winding drive unit 123 includes a winding drive member 1231, a driving pulley 1233, a driven pulley 1234, and a transmission belt 1232. The winding drive member 1231 is mounted on the mounting frame 110. The output end of the winding drive member 1231 is connected to the driving pulley 1233 to drive the driving pulley 1233 to rotate. The driven pulley 1234 is coaxially connected to the winding shaft 122. The transmission belt 1232 is wound around the driving pulley 1233 and the driven pulley 1234. When the winding drive member 1231 is in operation, it can drive the driving pulley 1233 to rotate. The transmission belt 1232 drives the driven pulley 1234 and the winding shaft 122 coaxially connected to the driven pulley 1234 to rotate, thereby achieving the recovery of the release paper. In this embodiment, the winding drive member 1231 is a second motor.

[0055] Optionally, in this embodiment, the tape feeding assembly further includes a unwinding drive unit 127, which is disposed on the mounting frame 110, and the output end of the unwinding drive unit 127 is connected to the unwinding shaft 121 to drive the reeling shaft 122 to rotate, thereby realizing the release of the label tape 1000.

[0056] FIG4 shows a partial enlarged view of FIG1 at B. As shown in FIG4 and in combination with FIG1, the tape feeding assembly further includes a tape pulling structure 124 and a tape pressing structure 125 located between the label stripping assembly 130 and the reel 122. The tape pulling structure 124 includes a tape pulling roller 1241 and a tape pulling driving member 1242. The tape pulling driving member 1242 is disposed on the mounting frame 110, and the output end of the tape pulling driving member 1242 is connected to the tape pulling roller 1241 to drive the tape pulling roller 1241 to rotate; the tape pressing structure 125 includes a tape pressing driving member 1251, a belt holding frame 1252, and a belt holding roller 1253. The belt holding roller 1253 is rotatably mounted on the belt holding frame 1252. The belt holding driver 1251 is mounted on the mounting frame 110, and the output end of the belt holding driver 1251 is connected to the belt holding frame 1252 to drive the belt holding roller 1253 toward the tape pull roller 1241 via the belt holding frame 1252, so that the tape pull roller 1241 and the belt holding roller 1253 can jointly compress the label tape 1000. Because the tape pull roller 1241 and the belt holding roller 1253 can jointly compress the label tape 1000, when the belt holding driver 1242 is in operation, it can drive the tape pull roller 1241 to rotate, thereby driving the label tape 1000 to move. Optionally, in this embodiment, the belt holding driver 1251 is a driving device having a linear drive function, such as a cylinder or an electric cylinder.

[0057] When the labeling device is in operation, the reel drive unit 123 is always in operation; the belt drive 1242 only drives a preset length of release paper at a time. After the reel drive unit 123 drives the reel shaft 122 to rotate and reel the preset length of release paper, the transmission belt 1232 slips against the active pulley 1233 and the driven pulley 1234 to maintain the normal operation of the labeling device. In addition, when the label tape 1000 is transferred between the unwinding shaft 121 and the belt drive structure 124, the label peeling and labeling operations must be completed. In other words, the label tape 1000 must maintain stable tension during this process to prevent the label tape 1000 from slackening, which could cause wrinkles, bubbles, and substandard overlap and alignment on the finished label paper. Therefore, both the unwinding drive unit 127 and the belt drive 1242 use high-precision servo motors. When the label tape 1000 is transported between the pull-belt structure 124 and the reel 122, only the release paper needs to be recovered. Therefore, the tension requirement for the label tape 1000 is not high. Therefore, the reel drive unit 123 uses a motor plus pulley belt structure, which is easy to install and can reduce manufacturing costs. The arrow on the label tape 1000 in Figure 1 indicates the transport direction of the label tape 1000.

[0058] Optionally, the tape feed assembly further includes multiple tensioning rollers 126 spaced apart and rotatably positioned between the unwinding shaft 121 and the reeling shaft 122. The label tape 1000 can sequentially pass through these multiple tensioning rollers 126, with at least one tensioning roller 126 being vertically adjustable. The provision of multiple tensioning rollers 126 ensures that the label tape 1000 maintains stable tension during transport, keeping the tape 1000 in a constant tensioned state and thus ensuring labeling quality.

[0059] In some embodiments, the tape feed assembly further includes a tension adjustment unit 128. Each vertically adjustable tensioning roller 126 corresponds to a tension adjustment unit 128, and the tension adjustment unit 128 is capable of driving the corresponding tensioning roller 126 to move vertically. The tension adjustment unit 128 includes a tension adjustment cylinder, an adjustment rail, and an adjustment slider. The adjustment rail extends vertically and is mounted on the mounting frame 110. The adjustment slider slidably engages the adjustment rail. The output end of the tension adjustment cylinder is connected to the adjustment slider to drive the adjustment slider to move along the extension direction of the adjustment rail. The corresponding tensioning roller 126 is rotatably mounted on the adjustment slider. The solenoid valve of the tension adjustment cylinder can control the extension and contraction of the output end of the tension adjustment cylinder based on the tension of the label tape 1000 at that time, thereby driving the corresponding tensioning roller 126 to move vertically via the adjustment slider, thereby adjusting the position of the tensioning roller 126 to ensure that the label tape 1000 remains in a tensioned state throughout the entire transmission process.

[0060] Figure 5 shows a schematic structural diagram of the support mechanism 200 provided in this embodiment. As shown in Figure 5 and in conjunction with Figure 3 , the support mechanism 200 includes a lifting assembly 210 and a clamping assembly 220. The output end of the lifting assembly 210 is connected to the clamping assembly 220 to drive the clamping assembly 220 to move vertically. The label-applying object 2000 is rotatably clamped at the clamping end of the clamping assembly 220. The label roller lifting drive 310, via the label roller rotating drive 320, drives the label roller 330 to press the peeled label paper onto the label-applying object 2000. The label roller rotating drive 320 then drives the label roller 330 to rotate. The rotation of the label roller 330 also drives the label-applying object 2000 to rotate, thereby affixing the label paper to the surface of the label-applying object 2000.

[0061] In some embodiments, the clamping assembly 220 includes two clamping drivers 221 and two clamping blocks 222. The output end of each clamping driver 221 is rotatably connected to a clamping block 222 via a bearing. The two clamping blocks 222 are arranged opposite each other, and the clamping driver 221 can drive the corresponding clamping block 222 to move toward the other clamping block 222, so that both clamping blocks 222 simultaneously clamp the object 2000 to be labeled. The two clamping blocks 222 are the clamping ends of the clamping assembly 220. In this embodiment, the clamping driver 221 can be a drive device with a linear drive function, such as a pneumatic cylinder, an electric cylinder, or a linear motor.

[0062] Optionally, there are two lifting assemblies 210, each connected to a clamping drive 221 at its output. The lifting assemblies 210 can drive the corresponding clamping drive 221 and clamping block 222 to move vertically toward or away from the label roller 330. After labeling is completed on an item 2000 to be labeled, the lifting assemblies 210 drive the corresponding clamping drive 221 and clamping block 222 away from the label roller 330 to facilitate unloading and reloading of the item 2000 to be labeled. In this embodiment, the lifting assemblies 210 can be a drive device with a linear drive function, such as a pneumatic cylinder, an electric cylinder, or a linear motor.

[0063] In this embodiment, the mounting frame 110 is further provided with a position detection member 140, which is configured to detect whether the label tape 1000 has been transferred to the label peeling assembly 130. When the position detection member 140 detects that the label tape 1000 has been transferred to the label peeling assembly 130, the position detection member 140 transmits the signal to the control system, which in turn controls the operation of the carrier mechanism 200 and the label rolling mechanism 300. Optionally, the position detection member 140 is a color code sensor.

[0064] The following is a brief description of the workflow of the labeling equipment in conjunction with Figures 1 to 5:

[0065] 1) The operator installs the labeling part 2000 on the supporting mechanism 200;

[0066] 2) The reeling drive unit 123 and the unreeling drive unit 127 are started simultaneously, so that the unreeling shaft 121 releases the label tape 1000 and transmits it to the position of the label stripping plate 131. During the transmission process, the deviation detection component 420 detects the transmission position of the label tape 1000 in real time. When it detects that the transmission position of the label tape 1000 is deviated, it transmits a deviation signal to the control system of the labeling equipment. The control system then controls the correction drive component 410 to drive the entire film supply mechanism 100 to move in a direction perpendicular to the transmission direction of the label tape 1000 through the mounting frame 110, so as to correct the deviation of the label tape 1000.

[0067] 3) When the label tape 1000 is transferred to the peeling plate 131 , the label paper thereon can be peeled off from the release paper under the action of the sharp corner 1311 of the peeling plate 131 ;

[0068] 4) The pull-belt drive 1242 is activated to drive the pull-belt roller 1241 to rotate and cooperate with the reeling drive 123 to reel the release paper of a preset length. At the same time, the peeled label paper continues to move between the supporting mechanism 200 and the label rolling mechanism 300.

[0069] 5) The lifting assembly 210 drives the clamping assembly 220 and drives the labeling object 2000 clamped thereon to move upward. At the same time, the label roller lifting drive 310 drives the label roller 330 via the label roller rotating drive 320 to press the peeled label paper onto the labeling object 2000. Then, the label roller rotating drive 320 drives the label roller 330 to rotate. As the label roller 330 rotates, it also drives the labeling object 2000 to rotate, thereby attaching the label paper to the surface of the labeling object 2000.

[0070] 6) The label roller lifting drive 310 drives the label roller 330 upward through the label roller rotating drive 320. At the same time, the lifting assembly 210 drives the clamping assembly 220 and drives the clamped object 2000 to move downward. The operator can remove the labeled object 2000 from the supporting mechanism 200 and reinstall a new one.

[0071] 7) Repeat steps 2) to 6) until all the labels in the label tape 1000 wound on the unwinding reel 121 are affixed.
