Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, and in particular to an automatic labeling machine for cylindrical batteries. Background Technology

[0002] Labels are used to identify product information. During product manufacturing, labeling is required, and in existing technologies, labels are typically affixed to products using labeling machines. A Chinese patent application (application number 202220806250.4) discloses a label peeling device and an automatic labeling equipment. The automatic labeling equipment includes the label peeling device, which comprises a sliding device, a driving device, and a guiding device. The guiding device restricts the sliding device to linear movement only. A peeling mechanism is provided on the sliding device to separate the label from the backing paper. The driving device rotates and pushes the sliding device, causing it to drive the peeling mechanism. The rotating driving device not only makes it easier to control the rotation speed and output force but also allows for various movement modes with different trajectories, offering better compatibility. However, the automatic labeling equipment disclosed in this patent cannot affix labels to cylindrical batteries and requires pre-prepared rolls of label tape with pre-formed labels. Furthermore, during the processing of the label tape rolls, the gap between adjacent labels on the tape is relatively large, generating waste and resource waste, which is detrimental to energy conservation and environmental protection. Therefore, the defects are very obvious, and a solution is urgently needed. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide an automatic labeling machine for cylindrical batteries.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic labeling machine for cylindrical batteries includes a machine base, a side frame disposed on one side of the top of the machine base, a battery conveying mechanism mounted on the machine base and located on one side of the side frame, a labeling device mounted on the machine base and positioned above the conveying surface of the battery conveying mechanism, a label rolling mechanism positioned above the conveying surface of the battery conveying mechanism and located on the discharge side of the labeling device, an unwinding mechanism mounted on the side frame, a web guiding mechanism mounted on the side frame and located on the discharge side of the unwinding mechanism, a label tape cutting mechanism mounted on the side frame and located on the discharge side of the web guiding mechanism, multiple feed guide rollers rotatably connected to the side frame, and a winding mechanism mounted on the side frame. The multiple feed guide rollers are distributed on the label tape cutting machine. Between the discharge side of the labeling device and the feed side of the labeling device, the unwinding mechanism is used to release the label tape, the label tape cutting mechanism is used to cut slits on the label tape released by the unwinding mechanism to form individual labels, the labeling device is used to peel the individual labels of the cut label tape off the base material tape and stick them onto the cylindrical batteries conveyed by the battery conveying mechanism, the label winding mechanism can drive the cylindrical batteries to rotate so that the labels are rolled onto the surface of the cylindrical batteries, and the winding mechanism is used to wind up the base material tape peeled off by the labeling device. The winding mechanism is located above the labeling device, and the unwinding mechanism, the correction mechanism and the label tape cutting mechanism are all located above the winding mechanism.

[0006] Furthermore, the labeling device includes a label holder mounted above the conveying surface of the battery conveying mechanism, a labeling roller rotatably connected to the label holder, a first rotary driver mounted on the label holder for driving the labeling roller to rotate, and a peeling plate mounted on the label holder and located above the labeling roller. The peeling end of the peeling plate is tangent to the top side of the labeling roller, and a peeling gap is formed between the peeling end of the peeling plate and the top side of the labeling roller. The labeling roller is rotatably mounted above the conveying surface of the battery conveying mechanism. The peripheral side of the labeling roller is provided with multiple suction holes. The suction holes are used to adsorb the label peeled off by the peeling plate onto the labeling roller. The labeling roller is used to stick the label onto the cylindrical battery conveyed by the battery conveying mechanism. The suction force of the suction holes is less than the adhesive force of the label sticking to the cylindrical battery. The label rolling mechanism is mounted on the label holder and located on the discharge side of the labeling roller.

[0007] Furthermore, the label holder is equipped with an installation rod, and the end of the peeling plate away from the label roller is mounted on the installation rod, with the peeling plate set at an angle.

[0008] Furthermore, a label recycling mechanism is installed on the side of the label holder away from the label application mechanism. The label recycling mechanism is used to collect the labels on the label application roller.

[0009] Furthermore, the label recycling mechanism includes a mounting base installed on the label holder and located above the conveying surface of the battery conveying mechanism, a mobile driver installed on the mounting base, a recycling component disposed at the moving end of the mobile driver, and a sensor installed on the mounting base. The mobile driver is used to drive the recycling component to move closer to or away from the label roller, and the sensor is used to sense the battery conveyed by the battery conveying mechanism. The sensor is electrically connected to the mobile driver.

[0010] Furthermore, the mobile end of the mobile drive is connected to the recyclable part via a connecting plate.

[0011] Furthermore, the connecting plate is a spring sheet, and the recycling component is a rotating wheel. One end of the spring sheet is fixedly connected to the moving end of the mobile driver, and the other end of the spring sheet is rotatably connected to the rotating wheel, which can roll and abut against the labeling roller. Specifically, the rotating wheel is a rubber wheel.

[0012] Furthermore, the battery conveying mechanism includes a base mounted on the machine platform, two sprockets rotatably connected to both ends of the base, two chains meshing and driving the two sprockets in parallel, a second rotation driver mounted on the base and used to drive at least one sprocket to rotate, and multiple carrier rollers rotatably arranged between the two chains. The multiple carrier rollers are arranged along the length of the chains, and the two ends of each carrier roller are rotatably connected to the corresponding links of the two chains. Two adjacent carrier rollers form a receiving cavity for accommodating cylindrical batteries.

[0013] Furthermore, the battery conveying mechanism also includes a battery supply mechanism installed above the feed end of the base, which is used to supply cylindrical batteries into the accommodating cavity.

[0014] Furthermore, the automatic labeling machine for cylindrical batteries also includes a roller pressing and bonding mechanism mounted above the conveying surface of the battery conveying mechanism. The roller pressing and bonding mechanism can drive the cylindrical batteries conveyed by the battery conveying mechanism to rotate in order to roll the cylindrical batteries with labels.

[0015] The beneficial effects of this utility model are as follows: In practical applications, the battery conveying mechanism conveys the flat cylindrical batteries. The label tape is composed of a label strip and a base material strip. The label tape roll is mounted on the unwinding mechanism, which drives the label tape roll to rotate so that the label tape roll releases the label tape. The label tape passes through the correction mechanism, which corrects the deviation of the moving label tape. The corrected label tape passes through the label strip cutting mechanism, which cuts the label strip to form individual labels. The label strip with cuts passes through multiple feed guide rollers and then through the labeling device. The labeling device separates the label from the base material strip and pastes the label onto the cylindrical battery conveyed by the battery conveying mechanism. The winding mechanism rewinds the separated / peeled base material strip. When the cylindrical battery with the label pasted passes through the labeling mechanism, the labeling mechanism drives the cylindrical battery to rotate so that the label is pasted onto the surface of the cylindrical battery. This allows the label to be firmly adhered to the surface of the cylindrical battery, and the battery conveying mechanism outputs the cylindrical battery with the label attached. This invention can cut slits in the label strip online to form individual labels. Because the slits are only cut into the label strip, no waste is generated during cutting, thus improving the utilization rate of the label strip, saving energy and protecting the environment. Furthermore, it can firmly adhere the label to the surface of the cylindrical battery, improving the quality of labeling. Attached Figure Description

[0021] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0022] like Figures 1 to 3 As shown, this utility model provides an automatic labeling machine for cylindrical batteries, which includes a machine base 1, a side frame 2 disposed on one side of the top of the machine base 1, a battery conveying mechanism 3 mounted on the machine base 1 and located on one side of the side frame 2, a labeling device 4 mounted on the machine base 1 and mounted above the conveying surface of the battery conveying mechanism 3, a label rolling and labeling mechanism 5 mounted 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 mounted on the side frame 2, a correction mechanism 7 mounted on the side frame 2 and located on the discharge side of the unwinding mechanism 6, a label tape cutting mechanism 8 mounted on the side frame 2 and located on the discharge side of the correction mechanism 7, a plurality of feed guide rollers 9 rotatably connected to the side frame 2, and a winding mechanism 10 mounted on the side frame 2. The plurality of feed guide rollers 9 are distributed on the discharge side of the label tape cutting mechanism 8 and the labeling device 4. Between the feeding 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 slits on the label tape released by the unwinding mechanism 6 to form individual labels, the labeling device 4 is used to peel the individual labels of the cut label tape off the base material tape and stick them onto the cylindrical battery 27 conveyed by the battery conveying mechanism 3, the label winding mechanism 5 can drive the cylindrical battery 27 to rotate so that the label is rolled onto the surface of the cylindrical battery 27, and the winding mechanism 10 is used to wind up the base material tape peeled off by the labeling device 4; specifically, the winding mechanism 10 is located above the labeling device 4, the unwinding mechanism 6, the correction mechanism 7 and the label tape cutting mechanism 8 are all located above the winding mechanism 10, and multiple feed guide rollers 9 are distributed in an arc shape on the outside of the winding mechanism 10.

[0023] In practical applications, the battery conveying mechanism 3 conveys the horizontally lying cylindrical batteries 27. The label tape is composed of a label adhesive tape and a base tape bonded together. The label tape roll is mounted on the unwinding mechanism 6, which drives the label tape roll to rotate, thus releasing the label tape. The label tape passes through the correction mechanism 7, which corrects the movement of the label tape. After correction, the label tape passes through the label adhesive tape cutting mechanism 8, which cuts the label adhesive tape of the label tape. Slits are cut into the label tape to form individual labels. The slit label tape, after passing through multiple feed rollers 9, goes through the labeling device 4. The labeling device 4 separates the label from the base tape and affixes the label to the cylindrical battery 27 conveyed by the battery conveying mechanism 3. The winding mechanism 10 winds up the separated / peeled base tape. As the labeled cylindrical battery 27 passes through the label winding mechanism 5, the label winding mechanism 5 drives the cylindrical battery 27 to rotate, causing the label to adhere firmly to the surface of the cylindrical battery 27. The battery conveying mechanism 3 then outputs the labeled cylindrical battery 27. This invention can cut slits in the label tape online to form individual labels on the label tape. Since the slits are only cut in the label tape, no waste is generated during cutting, and the label tape is not wasted, which improves the utilization rate of the label tape, saves energy and is environmentally friendly. It can also firmly roll the label onto the surface of the cylindrical battery 27, which improves the labeling quality of the cylindrical battery 27.

[0024] Specifically, the machine base 1 or side frame 2 is equipped with a controller, and the battery conveying mechanism 3, labeling device 4, label rolling mechanism 5, unwinding mechanism 6, web guiding mechanism 7, label tape cutting mechanism 8, and rewinding mechanism 10 are all electrically connected to the controller. In practical applications, operators can control the battery conveying mechanism 3, labeling device 4, label rolling mechanism 5, unwinding mechanism 6, web guiding mechanism 7, label tape cutting mechanism 8, and rewinding mechanism 10 through the controller.

[0025] Specifically, the label tape cutting mechanism 8 is equipped with a rotatable cutting roller, and multiple cutting blades are evenly spaced along the circumference of the cutting roller. In practical applications, the cutting roller rotates at a preset speed, and the multiple cutting blades on the rotating cutting roller cut slits on the label tape at equal intervals. Alternatively, the label tape cutting mechanism 8 is equipped with a translating cutting blade, which can reciprocate in the width direction of the label tape. In practical applications, the translating cutting blade cuts slits on the label tape. Or, the label tape cutting mechanism 8 is equipped with a lifting cutting blade, which can cut slits on the label tape.

[0026] In this embodiment, the labeling device 4 includes a label holder 11 mounted above the conveying surface of the battery conveying mechanism 3, a labeling roller 12 rotatably connected to the label holder 11, a first rotation driver mounted on the label holder 11 for driving the labeling roller 12 to rotate, and a peeling plate 13 mounted on the label holder 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 gap is formed between the peeling end of the peeling plate 13 and the top side surface of the labeling roller 12. In the peeling gap, the labeling roller 12 is rotatably positioned above the conveying surface of the battery conveying mechanism 3. The peripheral side of the labeling roller 12 is provided with multiple suction holes 14. The suction holes 14 are used to adsorb the label peeled off by the peeling plate 13 onto the labeling roller 12. The labeling roller 12 is used to stick the label onto the cylindrical battery 27 conveyed by the battery conveying mechanism 3. The suction force of the suction holes 14 is less than the adhesive force of the label sticking to the cylindrical battery 27. The label rolling mechanism 5 is installed on the label holder 11 and located on the discharge side of the labeling roller 12.

[0027] In practical applications, the label tape passes through multiple feed rollers 9 and then through the peeling gap. At this point, the label strip on the label tape faces downwards and is tightly adhered to the label roller 12. The base material of the label tape is bent by the peeling plate 13 and then wound onto 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 material and is sucked onto the label roller 12 through the suction hole 14. At this point, the adhesive side of the label faces outwards. As the first rotation driver drives the label roller 12 to rotate, the rotating label roller... Roller 12 drives the label to rotate. When the label rotates to correspond with the cylindrical battery 27 conveyed by the battery conveying mechanism 3, the suction force of the suction hole 14 is less than the adhesive force of the label on the cylindrical battery 27. Therefore, the label roller 12 sticks the label on the cylindrical battery 27. As the cylindrical battery 27 with the label is passed through the label winding mechanism 5, the label winding 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 onto the surface of the cylindrical battery 27.

[0028] Specifically, a vacuum channel is provided in the middle of the labeling roller 12, and multiple suction holes 14 are connected to the vacuum channel. The vacuum channel is a blind hole, and a rotary joint is connected to the open end of the vacuum channel. The rotary joint is connected to the vacuum pumping device via an air pipe and an air pressure regulating valve. This structural design facilitates that the multiple suction holes 14 are in a vacuum state, and the setting of the rotary joint ensures that the air pipe does not affect the rotation of the labeling roller 12.

[0029] In this embodiment, the label holder 11 is equipped with a mounting rod 15, and the end of the peeling plate 13 away from the label 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 helps the peeling plate 13 separate the base material strip from the label.

[0030] In this embodiment, a label recycling mechanism 16 is installed on the side of the label holder 11 away from the label rolling mechanism 5. The label recycling mechanism 16 is used to recycle the labels on the label rolling roller 12. In continuous production, the battery conveying mechanism 3 arranges and conveys multiple cylindrical batteries 27. When one cylindrical battery 27 is missing from a certain position among the multiple cylindrical batteries 27 being conveyed, in order to prevent the labels on the label rolling roller 12 from not being properly pasted and affecting the subsequent label peeling / labeling work, the label recycling mechanism 16 can recycle the labels on the label rolling roller 12, so that the label rolling roller 12 can normally label the subsequent cylindrical batteries 27.

[0031] In this embodiment, the label recycling mechanism 16 includes a mounting base 17 mounted on the label holder 11 and located above the conveying surface of the battery conveying mechanism 3, a mobile driver 18 mounted on the mounting base 17, a recycling component 19 disposed at the moving end of the mobile driver 18, and a sensor 20 mounted on the mounting base 17. The mobile driver 18 is used to drive the recycling component 19 to move closer to or away from the label roller 12, and the sensor 20 is used to sense the battery conveyed by the battery conveying mechanism 3. The sensor 20 is electrically connected to the mobile driver 18.

[0032] In practical applications, under continuous production conditions, the battery conveying mechanism 3 arranges and conveys multiple cylindrical batteries 27. When one cylindrical battery 27 is missing from a certain position among the multiple cylindrical batteries 27 being conveyed, the sensor 20 will not detect 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 component 19 to move closer to the labeling roller 12 until the recycling component 19 touches the label on the labeling roller 12, so that the label is pasted on the recycling component 19. Then the moving driver 18 drives the recycling component 19 and the label away from the labeling roller 12 to realize the recycling of the label.

[0033] Specifically, the mobile actuator 18 may be a cylinder.

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

[0035] In this embodiment, the connecting plate 21 is a spring sheet, the recycling component 19 is a rotating wheel, one end of the spring sheet is fixedly connected to the moving end of the moving driver 18, and the other end of the spring sheet is rotatably connected to the rotating wheel, which can roll against the label roller 12.

[0036] In practical applications, the mobile driver 18 drives the connecting plate 21, along with the recycling component 19, to move closer to the labeling roller 12 until the recycling component 19 comes into contact with the label on the labeling roller 12. Since the connecting plate 21 is a spring plate, the recycling component 19 will not have a hard impact collision with the labeling roller 12, thus protecting the recycling component 19, the label, and the labeling roller 12. Furthermore, since the recycling component 19 is a rotating wheel, when the recycling component 19 comes into contact with the label on the labeling roller 12, the recycling component 19 and the labeling roller 12 roll against each other. This not only helps the label on the labeling roller 12 to stick to the recycling component 19, but also reduces the friction between the recycling component 19 and the labeling roller 12, thus protecting the label.

[0037] Specifically, the roller is a rubber roller. The rubber roller has a certain degree of elasticity, which plays a role in cushioning and protection, further preventing the recycling component 19 from having a hard impact collision with the labeling roller 12, and also helps the label to be firmly adhered to the recycling component 19.

[0038] In this embodiment, the battery conveying mechanism 3 includes a base 22 mounted on the machine base 1, two sprockets rotatably connected to both ends of the base 22, two chains meshing and driving the two sprockets in parallel, a second rotation driver mounted on the base 22 and used to drive at least one sprocket to rotate, and a plurality of bearing rollers 23 rotatably disposed between the two chains. The plurality of bearing rollers 23 are arranged along the length direction of the chains, and the two ends of each bearing roller 23 are rotatably connected to the corresponding links of the two chains. Two adjacent bearing rollers 23 form a receiving cavity for accommodating the cylindrical battery 27.

[0039] In practical applications, the cylindrical battery 27 lies flat within the accommodating cavity, contacting two adjacent support rollers 23. These rollers support the cylindrical battery 27. A second rotary driver drives a sprocket to rotate, which in turn drives two chains. These chains then cause multiple support rollers 23 to move in a circular motion, thus moving the cylindrical battery 27 and transporting it. Furthermore, the support rollers 23 facilitate the label-applying mechanism 5's rotation of the cylindrical battery 27 on the battery transport mechanism 3, thereby ensuring the label is applied to the surface of the battery 27. This also facilitates the subsequent roller pressing and bonding mechanism 25's rotation of the cylindrical battery 27, ensuring the label is firmly pressed onto its surface.

[0040] In this embodiment, the battery conveying mechanism 3 further includes a battery supply mechanism 24 mounted above the feed end of the base 22. The battery supply mechanism 24 is used to supply cylindrical batteries 27 into the accommodating cavity. Specifically, the battery supply mechanism 24 includes cylindrical battery supply guide rails disposed above the two chains. In practical applications, the battery supply mechanism 24 automatically supplies cylindrical batteries 27 into each accommodating cavity to achieve automatic supply and conveying of cylindrical batteries 27.

[0041] In this embodiment, the automatic labeling machine for cylindrical batteries also includes a roller pressing and bonding mechanism 25 mounted above the conveying surface of the battery conveying mechanism 3. The roller pressing and bonding mechanism 25 can drive the cylindrical batteries 27 conveyed by the battery conveying mechanism 3 to rotate so as to roll the cylindrical batteries 27 with labels attached.

[0042] After the label roll-up mechanism 5 rolls the label onto the surface of the cylindrical battery 27, the roller pressing mechanism 25 then presses the label onto the surface of the cylindrical battery 27, further improving the adhesion of the label to the cylindrical battery 27.

[0043] Specifically, the roller pressing and bonding mechanism 25 includes a base mounted above the battery conveying mechanism 3, a roller pressing conveyor belt assembly rotatably mounted on the base, and a third rotary driver mounted on the base for driving the roller pressing conveyor belt assembly to rotate. The roller pressing conveyor belt assembly is located above the conveying surface of the battery conveying mechanism 3.

[0044] In practical applications, the third rotary driver drives the roller conveyor assembly to rotate. The rotating roller conveyor assembly contacts the surface of the cylindrical battery 27 with the label attached. Under the action of friction, the cylindrical battery 27 rotates. As the cylindrical battery 27 rotates, the roller conveyor assembly rolls the label on the cylindrical battery 27, so that the label is firmly attached to the cylindrical battery 27.

[0045] Specifically, the label rolling mechanism 5 includes a roll conveyor belt assembly rotatably disposed on the label holder 11 and a fourth rotation driver mounted on the label holder 11 for rotating the roll conveyor belt assembly. The roll conveyor belt assembly is located above the conveying surface of the battery conveying mechanism 3.

[0046] In practical applications, the fourth rotary driver drives the roll conveyor assembly to rotate. The rotating roll conveyor assembly abuts against the surface of the cylindrical battery 27 with the label attached. Under the action of friction, the cylindrical battery 27 rotates. As the cylindrical battery 27 rotates, the roll conveyor assembly rolls the label onto the surface of the cylindrical battery 27.

[0047] Specifically, the discharge end of the base 22 is equipped with a discharge guide plate 26, which guides the labeled cylindrical battery 27 output from the bearing roller 23 to the output.

[0048] Specifically, the side frame 2 is equipped with a correction device, which is located between the label tape cutting mechanism 8 and the feed roller 9. The correction device corrects the deviation of the cut label tape.

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

[0050] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
