[0002] Labels are used to identify product information. During product production, it is necessary to perform a labeling process on the product. In the prior art, a labeling machine is generally used to paste the label on the product. In the existing patent, a Chinese patent document with the application number 202220806250.4 discloses a label stripping device and an automatic labeling device. The automatic labeling device includes the label stripping device. The label stripping device includes a sliding device, a driving device, and a guiding device. The guiding device restricts the sliding device to move only in a straight line direction. A stripping device for separating the label from the backing paper is provided on the sliding device. The driving device rotates to push the sliding device, so that the sliding device drives the stripping device. The rotating driving device is not only easier to control the rotation speed and output force, but also can achieve various different trajectory motion modes by controlling the rotation angle, and has better compatibility. The automatic labeling device disclosed in this patent document cannot wind the label on the cylindrical battery, and it is necessary to prepare in advance a label tape roll with a formed label; in addition, when processing the label tape roll, the gap between two adjacent labels on the label tape will be relatively large, which will generate waste and cause waste of resources, and is not conducive to energy conservation and environmental protection. Therefore, the defect is very obvious, and a solution is urgently needed. Summary of the Invention

A peeling gap is formed between the peeling end of the peeling plate and the top side surface of the labeling roller. The labeling roller is rotatably arranged above the conveying surface of the battery conveying mechanism. A plurality of suction holes are arranged on the circumferential side surface of the labeling roller. The suction holes are used to adsorb the labels peeled off by the peeling plate on the labeling roller. The labeling roller is used to paste the labels on the cylindrical batteries conveyed by the battery conveying mechanism. The suction force of the suction holes is less than the adhesion force of the labels pasted on the cylindrical batteries. The roll labeling mechanism is installed on the label seat and located on the discharging side of the labeling roller.

[0007] Further, the label seat is provided with a mounting rod, and one end of the peeling plate away from the labeling roller is mounted on the mounting rod, and the peeling plate is inclined.

The label tape is formed by laminating a label sticking tape and a base tape. The label tape roll is installed on the unwinding mechanism, and the unwinding mechanism drives the label tape roll to rotate so that the label tape roll releases the label tape.

Moreover, the winding mechanism winds up the separated base tape. When the cylindrical battery after pasting the label passes through the label winding and pasting mechanism, the label winding and pasting mechanism drives the cylindrical battery to rotate self - sufficiently so that the label is wound and pasted on the surface of the cylindrical battery. This makes the label firmly adhered to the surface of the cylindrical battery, and the battery conveying mechanism outputs the cylindrical battery with the label pasted. The present invention can cut incisions on the label tape online to form individual labels on the label tape. Since only incisions are made on the label tape, no waste is generated during cutting, and there is no waste of the label tape, improving the utilization rate of the label tape, saving energy and protecting the environment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] For the convenience of those skilled in the art, the present invention will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the embodiments does not limit the present invention.

[0022] As Figures 1 to 3 shown, an automatic labeling device for cylindrical batteries provided by the present invention includes a machine table 1, a side frame 2 disposed on one side of the top of the machine table 1, a battery conveying mechanism 3 installed on the machine table 1 and located on one side of the side frame 2, a labeling device 4 installed on the machine table 1 and erected above the conveying surface of the battery conveying mechanism 3, a roll labeling mechanism 5 erected above the conveying surface of the battery conveying mechanism 3 and located on the discharge side of the labeling device 4, an unwinding mechanism 6 installed on the side frame 2, a deviation rectifying mechanism 7 installed on the side frame 2 and located on the discharge side of the unwinding mechanism 6, a label tape cutting mechanism 8 installed on the side frame 2 and located on the discharge side of the deviation rectifying mechanism 7, a plurality of tape guiding rollers 9 rotatably connected to the side frame 2, and a winding mechanism 10 installed on the side frame 2. The plurality of tape guiding rollers 9 are distributed between the discharge side of the label tape cutting mechanism 8 and the feed side of the labeling device 4. The unwinding mechanism 6 is used to release the label tape. The label tape cutting mechanism 8 is used to cut a notch on the label tape of the label tape released by the unwinding mechanism 6 to form individual labels. The labeling device 4 is used to peel the individual labels from the base tape of the cut label tape and paste them on the cylindrical battery 27 conveyed by the battery conveying mechanism 3. The roll labeling mechanism 5 can drive the cylindrical battery 27 to rotate so that the label is rolled on the surface of the cylindrical battery 27. The winding mechanism 10 is used to wind the base tape peeled off by the labeling device 4. Specifically, the winding mechanism 10 is located above the labeling device 4, and the unwinding mechanism 6, the deviation rectifying mechanism 7, and the label tape cutting mechanism 8 are all located above the winding mechanism 10. The plurality of tape guiding rollers 9 are arc-shaped and distributed outside the winding mechanism 10.

[0023] In practical applications, the battery conveying mechanism 3 conveys the flat cylindrical battery 27. The label tape is formed by laminating a label attaching tape and a base tape. The label tape roll is installed on the unwinding mechanism 6. The unwinding mechanism 6 drives the rotation of the label tape roll to release the label tape from the label tape roll. The label tape passes through the deviation rectifying mechanism 7, and the deviation rectifying mechanism 7 corrects the deviation of the moving label tape. The label tape after deviation rectification passes through the label attaching tape cutting mechanism 8. The label attaching tape cutting mechanism 8 cuts the label attaching tape of the label tape, making incisions on the label attaching tape to form individual labels. The label attaching tape with incisions passes around multiple tape guiding rollers 9 and then passes through the label pasting device 4. The label pasting device 4 separates the label from the base tape and pastes the label on the cylindrical battery 27 conveyed by the battery conveying mechanism 3. And the winding mechanism 10 winds up the separated / stripped base tape. When the cylindrical battery 27 with the label pasted passes through the label winding and pasting mechanism 5, the label winding and pasting mechanism 5 drives the cylindrical battery 27 to rotate self - sufficiently so that the label is wound and pasted on the surface of the cylindrical battery 27, making the label firmly pasted on the surface of the cylindrical battery 27. The battery conveying mechanism 3 outputs the cylindrical battery 27 with the label pasted. The present invention can cut incisions on the label tape in - line to form individual labels on the label tape. Since only incisions are cut on the label tape, no waste is generated during cutting, and there is no waste of the label tape, improving the utilization rate of the label tape, saving energy and being environmentally friendly. Moreover, the label can be firmly wound and pasted on the surface of the cylindrical battery 27, improving the labeling quality of the cylindrical battery 27.

[0024] Specifically, the machine table 1 or the side frame 2 is provided with a controller, and the battery conveying mechanism 3, the label pasting device 4, the label winding and pasting mechanism 5, the unwinding mechanism 6, the deviation rectifying mechanism 7, the label attaching tape cutting mechanism 8 and the winding mechanism 10 are all electrically connected to the controller. In practical applications, the operator can control the battery conveying mechanism 3, the label pasting device 4, the label winding and pasting mechanism 5, the unwinding mechanism 6, the deviation rectifying mechanism 7, the label attaching tape cutting mechanism 8 and the winding mechanism 10 through the controller.

[0025] Specifically, the label attaching tape cutting mechanism 8 is rotatably provided with a cutting roller, and a plurality of cutting knives are equidistantly arranged on the circumferential side of the cutting roller. In practical applications, the cutting roller rotates at a preset speed, and the plurality of cutting knives on the rotating cutting roller cut incisions on the label attaching tape of the label tape at equal intervals. Or, the label attaching tape cutting mechanism 8 is provided with a cutting knife arranged in translation, and the cutting knife can reciprocate in the width direction of the label tape. In practical applications, the translating cutting knife cuts incisions on the label attaching tape of the label tape. Or, the label attaching tape cutting mechanism 8 is provided with a cutting knife arranged in lifting, and the lifting cutting knife can cut incisions on the label attaching tape of the label tape.

[0026] In this embodiment, the labeling device 4 includes a label seat 11 erected above the conveying surface of the battery conveying mechanism 3, a labeling roller 12 rotatably connected to the label seat 11, a first rotation driver installed on the label seat 11 and used to drive the labeling roller 12 to rotate, and a peeling plate 13 installed on the label seat 11 and located above the labeling roller 12. The peeling end (peeling tip) of the peeling plate 13 is tangent to the top side surface of the labeling roller 12, and a peeling gap is formed between the peeling end of the peeling plate 13 and the top side surface of the labeling roller 12. The labeling roller 12 is rotatably arranged above the conveying surface of the battery conveying mechanism 3. A plurality of suction holes 14 are provided on the circumferential side surface of the labeling roller 12. The suction holes 14 are used to adsorb the label peeled off by the peeling plate 13 on the labeling roller 12. The labeling roller 12 is used to paste the label on the cylindrical battery 27 conveyed by the battery conveying mechanism 3. The suction force of the suction holes 14 is less than the adhesion force of the label pasted on the cylindrical battery 27; the roll labeling mechanism 5 is installed on the label seat 11 and located on the discharge side of the labeling roller 12.

[0027] In practical applications, the label tape passes through the peeling gap after passing around a plurality of tape guiding rollers 9. At this time, the label on the label tape is attached downward and closely attached to the labeling roller 12. The base tape of the label tape is bent after passing through the peeling plate 13 and wound around the winding shaft of the winding mechanism 10. Under the action of the peeling tip of the peeling plate 13, the label is separated from the base tape and adsorbed tightly on the labeling roller 12 through the suction holes 14. At this time, the pasting surface of the label faces outward. As the first rotation driver drives the labeling roller 12 to rotate, the rotating labeling roller 12 drives the label to rotate. When the label rotates to correspond to the cylindrical battery 27 conveyed by the battery conveying mechanism 3, since the suction force of the suction holes 14 is less than the adhesion force of the label pasted on the cylindrical battery 27, the labeling roller 12 pastes the label on the cylindrical battery 27. During the process of the cylindrical battery 27 with the label passing through the roll labeling mechanism 5, the roll labeling mechanism 5 drives the cylindrical battery 27 to rotate on the battery conveying mechanism 3. As the cylindrical battery 27 rotates, the label will be rolled and pasted on the surface of the cylindrical battery 27.

[0028] Specifically, a vacuum channel is provided in the middle of the labeling roller 12. A plurality of suction holes 14 are all communicated with the vacuum channel. The vacuum channel is a blind hole. The open end of the vacuum channel is connected with a rotary joint. The rotary joint is communicated with a vacuum pumping device via an air pipe and a pneumatic regulating valve. This structural design facilitates the plurality of suction holes 14 to be in a vacuum state, and the setting of the rotary joint enables the air pipe not to affect the rotation of the labeling roller 12.

[0029] In this embodiment, the label seat 11 is provided with a mounting rod 15, and one end of the peeling plate 13 away from the labeling roller 12 is mounted on the mounting rod 15. This structural design facilitates the assembly of the peeling plate 13; specifically, the peeling plate 13 is inclined, which is beneficial to the peeling plate 13 to separate the base tape from the label.

[0030] In this embodiment, a label recycling mechanism 16 is installed on the side of the label seat 11 away from the label winding and pasting mechanism 5. The label recycling mechanism 16 is used to recycle the labels on the label pasting roller 12. In the case of continuous production, the battery conveying mechanism 3 arranges and conveys a plurality of cylindrical batteries 27. When one of the cylindrical batteries 27 is missing at a certain position among the arranged and conveyed cylindrical batteries 27, in order to prevent the label on the label pasting roller 12 from being unable to be pasted normally and affecting the subsequent label peeling / labeling work, the label recycling mechanism 16 can recycle the label on the label pasting roller 12, so that the label pasting roller 12 can normally paste labels on the subsequent cylindrical batteries 27.

[0031] In this embodiment, the label recycling mechanism 16 includes a mounting seat 17 installed on the label seat 11 and above the conveying surface of the battery conveying mechanism 3, a moving driver 18 installed on the mounting seat 17, a recycling member 19 arranged at the moving end of the moving driver 18, and a sensor 20 installed on the mounting seat 17. The moving driver 18 is used to drive the recycling member 19 to approach or move away from the label pasting roller 12, and the sensor 20 is used to sense the batteries conveyed by the battery conveying mechanism 3. The sensor 20 is electrically connected to the moving driver 18.

[0032] In practical applications, in the case of continuous production, the battery conveying mechanism 3 arranges and conveys a plurality of cylindrical batteries 27. When one of the cylindrical batteries 27 is missing at a certain position among the arranged and conveyed cylindrical batteries 27, the sensor 20 cannot sense the cylindrical battery 27. The sensor 20 will send a signal to the moving driver 18, causing the moving driver 18 to drive the recycling member 19 to move closer to the label pasting roller 12 until the recycling member 19 touches the label on the label pasting roller 12, so that the label is pasted on the recycling member 19. Then, the moving driver 18 drives the recycling member 19 to move away from the label pasting roller 12 together with the label to achieve the recycling of the label.

[0033] Specifically, the moving driver 18 can be a cylinder.

[0034] In this embodiment, the moving end of the moving driver 18 is connected to the recycling member 19 via a connecting plate 21. This structural design facilitates the assembly of the recycling member 19 and the moving driver 18.

[0035] In this embodiment, the connecting plate 21 is a spring piece, and the recycling member 19 is a rotating wheel. One end of the spring piece is fixedly connected to the moving end of the moving driver 18, and the other end of the spring piece is rotatably connected to the rotating wheel. The rotating wheel can roll and touch the label pasting roller 12.

[0036] In practical applications, the moving driver 18 drives the connecting plate 21 and the recycling member 19 to move closer to the labeling roller 12 until the recycling member 19 abuts against the label on the labeling roller 12. Since the connecting plate 21 is an elastic piece, the recycling member 19 will not have a hard impact collision with the labeling roller 12, which plays a protective role for the recycling member 19, the label, and the labeling roller 12. Also, since the recycling member 19 is a rotating wheel, when the recycling member 19 abuts against the label on the labeling roller 12, the recycling member 19 rolls against the labeling roller 12, which not only facilitates the adhesion of the label on the labeling roller 12 to the recycling member 19 but also reduces the friction between the recycling member 19 and the labeling roller 12, playing a protective role for the label.

[0037] Specifically, the rotating wheel is a rubber wheel. The rubber wheel has a certain elasticity and plays a role in buffering and protecting, further preventing the recycling member 19 from having a hard impact collision with the labeling roller 12 and facilitating the firm adhesion of the label to the recycling member 19.

[0038] In this embodiment, the battery conveying mechanism 3 includes a seat body 22 installed on the machine table 1, two sprockets respectively rotatably connected to both ends of the seat body 22, two chains parallelly meshing and drivingly connected to the two sprockets, a second rotating driver installed on the seat body 22 and used to drive at least one sprocket to rotate, and a plurality of carrying rollers 23 rotatably arranged between the two chains. The plurality of carrying rollers 23 are arranged along the length direction of the chains, and both ends of each carrying roller 23 are respectively rotatably connected to the corresponding chain links of the two chains. Adjacent two carrying rollers 23 form a receiving cavity for accommodating the cylindrical battery 27.

[0039] In practical applications, the cylindrical battery 27 lies flat in the receiving cavity, the cylindrical battery 27 abuts against the adjacent two carrying rollers 23, and the adjacent two carrying rollers 23 support the cylindrical battery 27. The second rotating driver drives the sprocket to rotate, the rotating sprocket drives the two chains to rotate, and the rotating two chains drive the plurality of carrying rollers 23 to move in a looped cycle to drive the cylindrical battery 27 to move, thereby realizing the conveying of the cylindrical battery 27. In addition, the arrangement of the carrying rollers 23 is conducive to the labeling mechanism 5 driving the cylindrical battery 27 to rotate on the battery conveying mechanism 3, which is conducive to the label being wound and pasted on the surface of the cylindrical battery 27 and also conducive to the subsequent roller pressing and fitting mechanism 25 driving the cylindrical battery 27 to rotate so that the label is firmly roller pressed on the surface of the cylindrical battery 27.

[0040] In this embodiment, the battery conveying mechanism 3 further includes a battery supply mechanism 24 installed above the feeding end of the seat body 22, and the battery supply mechanism 24 is used to supply the cylindrical battery 27 to the receiving cavity. Specifically, the battery supply mechanism 24 includes a guide rail for supplying cylindrical batteries arranged above the two chains. In practical applications, the battery supply mechanism 24 automatically supplies the cylindrical battery 27 to each receiving cavity to realize the automatic supply and conveying of the cylindrical battery 27.

[0041] In this embodiment, the cylindrical battery automatic labeling device further includes a roll-pressing and laminating mechanism 25 mounted above the conveying surface of the battery conveying mechanism 3. The roll-pressing and laminating mechanism 25 can drive the cylindrical battery 27 conveyed by the battery conveying mechanism 3 to rotate self - sufficiently to roll - press the cylindrical battery 27 with a label rolled thereon.

[0042] After the label - rolling mechanism 5 rolls the label on the surface of the cylindrical battery 27, the roll - pressing and laminating mechanism 25 further rolls the label on the surface of the cylindrical battery 27, further improving the firmness of the label adhered to the cylindrical battery 27.

[0043] Specifically, the roll - pressing and laminating mechanism 25 includes a base mounted above the battery conveying mechanism 3, a roll - pressing conveyor belt assembly rotatably arranged on the base, and a third rotation driver mounted on the base and used to drive the roll - pressing conveyor belt assembly to rotate. The roll - pressing conveyor belt assembly is located above the conveying surface of the battery conveying mechanism 3.

[0044] In practical applications, the third rotation driver drives the roll - pressing conveyor belt assembly to rotate. The rotating roll - pressing conveyor belt assembly abuts against the surface of the cylindrical battery 27 with a label adhered thereon. Under the action of frictional force, the cylindrical battery 27 rotates self - sufficiently. As the cylindrical battery 27 rotates, the roll - pressing conveyor belt assembly rolls - presses the label on the cylindrical battery 27, making the label firmly adhered to the cylindrical battery 27.

[0045] Specifically, the label - rolling mechanism 5 includes a roll - pasting conveyor belt assembly rotatably arranged on the label seat 11, and a fourth rotation driver mounted on the label seat 11 and used to drive the roll - pasting conveyor belt assembly to rotate. The roll - pasting conveyor belt assembly is located above the conveying surface of the battery conveying mechanism 3.

[0046] In practical applications, the fourth rotation driver drives the roll - pasting conveyor belt assembly to rotate. The rotating roll - pasting conveyor belt assembly abuts against the surface of the cylindrical battery 27 with a label adhered thereon. Under the action of frictional force, the cylindrical battery 27 rotates self - sufficiently. As the cylindrical battery 27 rotates, the roll - pasting conveyor belt assembly rolls the label on the surface of the cylindrical battery 27.

[0047] Specifically, a discharge guide plate 26 is installed at the discharge end of the seat body 22. The discharge guide plate 26 guides the labeled cylindrical battery 27 output by the carrying roller 23 for output.

[0048] Specifically, the side frame 2 is equipped with a deviation - rectifying device. The deviation - rectifying device is located between the label tape cutting mechanism 8 and the incoming - belt guide roller 9. The deviation - rectifying device rectifies the cut label tape.

[0049] All the technical features in this embodiment can be freely combined according to actual needs.

[0050] The above embodiments are preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
