The label roller lifting drive element 310, via the label roller rotating drive element 320, can drive the labeling roller 330 to move it up and down in the vertical direction, thereby moving the detached label paper close to the piece 2000 to be labeled on the support mechanism 200 and pressing the label paper onto the piece 2000 to be labeled.wherein the label roller rotation drive element 320 can drive the label roller 330 to rotate in order to adhere the label paper to the piece 2000 to be labeled.

[0023] In the present embodiment, the piece 2000 to be labeled primarily refers to a cylindrical battery. Of course, in other embodiments, the piece 2000 to be labeled may also be other cylindrical products that require label paper to be adhered to the surface.

[0024] In the labeling device provided in this embodiment, during labeling, first, the piece 2000 to be labeled is supported on the support mechanism 200, the tape feed component transports the label tape 1000 to the label peeling component 130, and the label peeling component 130 can peel the label paper from the release paper; then, the label roller elevating drive member 310, via the label roller rotating drive member 320, can drive the labeling roller 330 to move it vertically downward, thereby moving the peeled label paper close to the piece 2000 to be labeled on the support mechanism 200 and pressing the label paper onto the piece 2000 to be labeled;The label roller rotation drive element 320 then drives the label roller 330 to rotate, and meanwhile, the piece 2000 to be labeled moves along with it, so that the label paper located between the label roller 330 and the piece 2000 to be labeled is adhered to the outer surface of the piece 2000 to be labeled. Through the cooperation of the film feed mechanism 100, the support mechanism 200, and the label roller mechanism 300, the automatic labeling process of label paper can be realized. Compared with manual labeling in the prior art, it can not only improve labeling efficiency and reduce labor costs, but also ensure labeling quality and improve the yield of the finished products.

Of course, in other embodiments, the label roller lifting drive element 310 can also be a drive device with a linear drive function, for example, an oil cylinder or an electric cylinder.

[0026] As in the Fig. 1 and Fig. 3, the label peeling component 130 includes a label peeling plate 131, with a sharp corner 1311 provided on the side of the label peeling plate 131 facing the support mechanism 200. When the tape feed component drives the label tape 1000 to pass through the label peeling plate 131, the label tape 1000 can peel the label paper from the release paper under the action of the sharp corner 1311. As the label tape 1000 continues to be transported, the peeled label paper continues to move between the support mechanism 200 and the label rolling mechanism 300; then, the labeling roller 330 can move downward to press the label paper onto the piece 2000 to be labeled on the support mechanism 200, and by rotating, the label paper is adhered to the surface of the piece 2000 to be labeled.

[0027] The label release component 130 further includes a limiting block 132, wherein the limiting block 132 is arranged upstream of the label release plate 131 and a limiting groove 1321 is provided on a side of the limiting block 132 facing the label release plate 131, wherein the label tape 1000 can pass between the limiting groove 1321 and the label release plate 131. By arranging the limiting block 132 with the limiting groove 1321, the label tape 1000 passing through the label release plate 131 can be limited to prevent the position of the label tape 1000 from shifting as it passes through the label release plate 131, thereby impairing the labeling effect.

[0028] The label release component 130 further includes a limit stop plate 133, wherein two limit guide plates 133 are arranged on either side of the label release plate 131 along the transfer direction perpendicular to the label strip 1000, wherein the label strip 1000 can pass between the two limit stop plates 133.

Before the label tape 1000 is transferred to the label peeling component 130, the offset detection component 420 first detects the transfer position of the label tape 1000.When it is detected that the label tape 1000 deviates from the preset position, the detection result is transmitted to the transmission system of the labeling device, and the transmission system controls the correction drive component 410 to activate so that the entire film feed mechanism 100 is driven to move by the mounting frame 110 in a direction perpendicular to the transfer direction of the label tape 1000, thereby adjusting the transfer position of the label tape 1000.

The offset detection element 421 can receive the image information of the label tape 1000 and transmit the image information to the control system of the labeling device. The control system can determine whether an offset exists in the transfer position of the label tape 1000 by comparing the standard image information with the current image information. Optionally, the offset detection element 421 is an electric ultrasonic eye.

[0033] As in the Fig. 1 and Fig. 2, the tape feed component includes a supply shaft 121, a take-up shaft 122, and a take-up drive 123, wherein the supply shaft 121 and the take-up shaft 122 are spaced apart and rotatably mounted on the mounting frame 110, wherein the supply shaft 121 is used to release the label tape 1000 and the take-up shaft 122 is used to wind up the release paper of the detached label paper, wherein the take-up drive 123 is provided on the mounting frame 110 and is configured to drive the take-up shaft 122 to rotate, thereby driving the label tape 1000 to pass through the label release component 130.

[0034] Specifically, the take-up drive 123 includes a take-up drive element 1231, a drive pulley, a driven pulley, and a transmission belt 1232. The take-up drive element 1231 is mounted on the mounting frame 110. The output end of the take-up drive element 1231 is connected to the drive pulley to drive the drive pulley to rotate. The driven pulley is coaxially connected to the take-up shaft 122, and the transmission belt 1232 is wound around the drive pulley and the driven pulley. When the take-up drive element 1231 operates, it can drive the drive pulley to rotate and the driven pulley and the take-up shaft 122, which are coaxially connected to the driven pulley, to rotate via the transmission belt 1232, thereby realizing the recovery of release paper.In the present embodiment, the winding drive element 1231 is a second motor.

[0035] Optionally, in the present embodiment, the tape feed component further comprises an unwind drive 127, wherein the unwind drive 127 is arranged on the mounting frame 110, wherein the output end of the unwind drive 127 is connected to the unwind shaft 121 to drive the take-up shaft 122 to rotate, thereby releasing the label tape 1000.

[0036] Fig. 4 shows an enlarged partial view of Fig. 1 at B. As in Fig. 4 in conjunction with the Fig. 1 and Fig. 2, the tape feeding component also includes a tape pulling structure 124 and a tape pressing structure 125 disposed between the label peeling component 130 and the take-up shaft 122, wherein the tape pulling structure 124 includes a tape pulling roller 1241 and a tape pulling drive 1242, and the tape pulling drive 1242 is provided on the mounting frame 110, and wherein the output end of the tape pulling drive 1242 is connected to the tape pulling roller 1241 to drive the tape pulling roller 1241 to rotate; wherein the tape printing structure 125 comprises a tape printing drive 1251, a tape printing movement frame 1252 and a tape printing roller 1253, wherein the tape printing roller 1253 is rotatably provided on the tape printing movement frame 1252, and the tape printing drive 1251 is arranged on the mounting frame 110, and wherein the output end of the tape printing drive 1251 is connected to the tape printing movement frame 1252,to drive the tape pressure roller 1253 through the tape pressure movement frame 1252 into proximity with the tape pull roller 1241, so that the tape pull roller 1241 and the tape pressure roller 1253 can jointly press the label tape 1000. The tape pull roller 1241 and the tape pressure roller 1253 can jointly press the label tape 1000.

Optionally, in the present embodiment, the tape pressure drive 1251 is a drive device with a linear drive function, for example, an air cylinder or an electric cylinder.

[0037] Note that the take-up drive 123 is always in the operating state when the labeling device is operating; in contrast, the tape pulling drive 1242 only drives the release paper of a preset length to move at a time. After the take-up drive 123 rotates the take-up shaft 122 to wind the release paper of the preset length, the transfer belt 1232 slips with the drive pulley and the driven pulley to maintain normal operation of the labeling device. Furthermore, when the label tape 1000 is transported between the unwind shaft 121 and the tape pulling structure 124, the label peeling and labeling processes must be completed.That is, the label tape 1000 must maintain stable tension during the process to avoid loosening of the label tape 1000, which can lead to wrinkles, bubbles, and unsatisfactory overlap and alignment of the label paper on the final product. Therefore, both the unwind drive 127 and the tape pulling drive 1242 use higher-precision servo motors. On the other hand, when the label tape 1000 is transported between the tape pulling structure 124 and the take-up shaft 122, only the release paper needs to be recovered, and the tension requirement for the label tape 1000 is not high. Therefore, the take-up drive 123 adopts a motor-plus-pulley-belt structure, which facilitates installation and can reduce manufacturing costs. The direction of the arrow on the label tape 1000 in .

By arranging a plurality of tension rollers 126, it can be ensured that the label tape 1000 maintains a stable tension during the transfer process, so that the label tape 1000 is always in a taut state, thus ensuring labeling quality.

[0039] In addition, the tape feed component also includes a tension adjustment section 128, wherein each vertically adjustable tension roller 126 corresponds to a tension adjustment section 128, wherein the tension adjustment section 128 can drive the corresponding tension roller 126 to move in the vertical direction.

As in Fig. 5 in conjunction with Fig. 3, the support mechanism 200 includes a lifting component 210 and a clamping component 220. The output end of the lifting component 210 is connected to the clamping component 220 to drive the clamping component 220 to move vertically, with the piece 2000 to be labeled being rotatably clamped at the clamping end of the clamping component 220. The label roller lifting drive member 310 drives the labeling roller 330 via the label roller rotating drive member 320 to press the peeled label paper onto the piece 2000 to be labeled, and then the label roller rotating drive member 320 drives the labeling roller 330 to rotate. When the labeling roller 330 rotates, it can also cause the piece 2000 to be labeled to rotate, thereby causing the label paper to be adhered to the surface of the piece 2000 to be labeled.

[0041] Specifically, the clamping component 220 includes two clamping drive elements 221 and two clamping blocks 222, wherein the output end of each clamping drive element 221 is rotatably connected to a clamping block 222 via a bearing, wherein the two clamping blocks 222 are arranged opposite each other, and the clamping drive element 221 can drive the corresponding clamping block 222 to move it in a direction closer to the other clamping block 222, thus the two clamping blocks 222 simultaneously clamp the piece 2000 to be labeled. The two clamping blocks 222 are the clamping ends of the clamping component 220. In the present embodiment, the clamping drive element 221 can be a drive device with a linear drive function, for example, an air cylinder, an electric cylinder, or a linear motor.

[0042] Optionally, the lifting component 210 is provided in two, with the output end of each lifting component 210 being connected to a clamp drive element 221, wherein the lifting component 210 can drive the corresponding clamp drive element 221 and the clamp block 222 to move them vertically and toward or away from the labeling roller 330. When the labeling of a piece 2000 to be labeled is completed, the lifting component 210 drives the corresponding clamp drive element 221 and the clamp block 222 to move them in a direction away from the labeling roller 330 to facilitate the unloading and transfer of the piece 2000 to be labeled. In the present embodiment, the lifting component 210 can be a drive device with a linear drive function, for example, an air cylinder, an electric cylinder, or a linear motor.

[0043] In the present embodiment, the mounting frame 110 is also equipped with an in-situ sensing component 140, wherein the in-situ sensing component 140 is used to detect whether the label web 1000 is being transported to the label removal component 130. When the in-situ sensing component 140 detects that the label web 1000 has been transferred to the label removal component 130, the signal can be transmitted to the control system, which controls the actions of the support mechanism 200 and the label rolling mechanism 300. Optionally, the in-situ sensing component 140 is a color mark sensor.

[0044] Below you will find a brief description of the working process of this labeling device in conjunction with the Fig. 1 to 5: 1) The operator places the piece 2000 to be labeled on the carrying mechanism 200; 2) The take-up drive 123 and the unwind drive 127 are started simultaneously, so that the unwind shaft 121 releases the label tape 1000 and transfers it to the position of the label peeling plate 131. During the transfer operation, the offset detection component 420 detects the transfer position of the label tape 1000 in real time. If it is determined that the transfer position of the label tape 1000 is offset, an offset signal is transmitted to the control system of the labeling device, and the control system then controls the correction drive component 410 to drive the entire film feed mechanism 100 through the mounting frame 110 to move in a direction perpendicular to the transfer direction of the label tape 1000, thus realizing the correction operation of the label tape 1000. 3) When the label tape 1000 is transferred to the label release plate 131, it can be peeled off from the release paper under the action of the sharp corner 1311 of the label release plate 131; 4) The tape pulling drive 1242 is activated to drive the tape pulling roller 1241 to rotate and cooperate with the take-up drive 123 to wind up the release paper of the preset length, meanwhile, the detached label paper continues to move between the carrying mechanism 200 and the label rolling mechanism 300; 5) The lifting component 210 drives the clamping component 220 and moves the piece to be labeled 2000 clamped thereon upward. Meanwhile, the label roller lifting drive element 310 drives the labeling roller 330 via the label roller rotating drive element 320 to press the peeled label paper onto the piece to be labeled 2000. Then, the label roller rotating drive element 320 drives the labeling roller 330 to rotate. When the labeling roller 330 rotates, it can also rotate the piece to be labeled 2000, thereby adhering the label paper to the surface of the piece to be labeled 2000. 6) The label roller lifting drive member 310 drives the labeling roller 330 to move upward via the label roller rotating drive member 320, meanwhile, the lifting component 210 drives the clamping component 220 and moves the piece to be labeled 2000 clamped thereto downward, whereby the operator can remove the piece to be labeled 2000 that has completed the labeling operation from the support mechanism 200 and then remount a new piece to be labeled 2000; 7) Steps 2) to 6) can be repeated until the label paper is completely glued to the label tape 1000 wound on the unwind shaft 121.
