Description

Technical Field

[0001] This invention relates to the field of label application technology, and in particular to a labeling method, system, device and storage medium for a labeling machine. Background Technology

[0002] Currently, labeling machines are frequently used in battery production to affix labels to the battery surface to distinguish superior and inferior batteries. Traditional labeling methods involve labeling at the same speed as the product transport, applying the labels during transit. However, the relatively low transport speed of traditional methods limits labeling speed, resulting in low production efficiency. Conversely, increasing transport speed necessitates maintaining the labeling machine's high-speed output to match, which can easily lead to label misapplication. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, one of the objectives of this invention is to provide a labeling method for a labeling machine, which improves labeling efficiency by applying labels by tearing them off.

[0004] The second objective of this invention is to provide a labeling system that performs the above-described labeling method.

[0005] The third objective of this invention is to provide an electronic device.

[0006] The fourth objective of this invention is to provide a computer-readable storage medium.

[0007] One of the objectives of this invention is achieved through the following technical solution:

[0008] A labeling method for a labeling machine, comprising:

[0009] The system responds to high-speed labeling commands and controls the target object to be labeled to move forward continuously.

[0010] When a positioning message is received indicating that the target object has moved to a designated position, the labeling machine is controlled to dispense a partial label based on the positioning message, and the pressure roller of the labeling machine is controlled to press down the dispensed label and stick it to the target object; as the target object continues to move forward, the label pasted on the target object is completely pulled out of the labeling machine and completely pasted onto the surface of the target object.

[0011] Furthermore, the high-speed labeling command is generated based on the forward speed of the target object. The high-speed labeling command is generated when it is detected that the forward speed of the target object is greater than a preset speed.

[0012] Furthermore, when the forward speed of the target object is detected to be less than the preset speed, a low-speed labeling instruction is generated; the labeling machine responds to the low-speed labeling instruction by adjusting the labeling machine's labeling mode so that the labeling machine can completely label the target object and its labeling speed is the same as the forward speed of the target object for synchronous labeling.

[0013] Furthermore, when the labeling machine dispenses a partial label, the length of the dispensed label is greater than or equal to the distance between the labeling machine's dispensing port and the pressure roller.

[0014] Furthermore, when the labeling machine dispenses a partial label, the length of the dispensed label is at least one-third of the total length of the label, so that the label extends to the position directly opposite the pressure roller for labeling.

[0015] Furthermore, the labeling machine's label outlet is tilted towards the target object, causing the label to be dispensed at an angle.

[0016] Furthermore, after each label is applied, the process also includes: collecting the label dispensing signal, calculating the label size, comparing the label size with the labeling method of the current labeling machine, and generating an alarm prompt if the label size does not match the labeling method during the comparison process.

[0017] The second objective of this invention is achieved by the following technical solution:

[0018] A labeling system that performs the labeling method of the labeling machine described above; the system includes:

[0019] The transport control module is used to control the continuous movement of the target object to be labeled;

[0020] The positioning detection module is used to detect whether the target object has moved to the designated position;

[0021] The label dispensing control module is used to control the labeling machine to dispense partial labels according to the arrival message, and to control the pressure roller of the labeling machine to press down the dispensed labels and stick them to the target object; as the target object continues to move forward, the labels pasted on the target object are completely pulled out of the labeling machine and completely pasted onto the surface of the target object.

[0022] The third objective of this invention is achieved by the following technical solution:

[0023] An electronic device includes a processor, a memory, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the labeling method of the labeling machine as described above.

[0024] The fourth objective of this invention is achieved by the following technical solution:

[0025] A computer-readable storage medium having a computer program stored thereon, which, when executed, implements the labeling method of the labeling machine as described above.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] When the target object is transported at high speed, the labeling machine partially dispenses the label and affixes it to the surface of the target object. As the target object moves forward at high speed, the label that was not fully dispensed is completely pulled out, and under the action of the pressure roller, the fully pulled-out label is completely affixed to the surface of the target object. This labeling method can be adapted to products transported at high speed, which greatly improves labeling efficiency. Attached Figure Description

[0033] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] This embodiment provides a labeling machine, the device including a housing 1, a label assembly, a drive assembly, and a label pressing assembly, etc.; Figure 1 , Figure 2 As shown, the label assembly includes multiple sets of rollers 2. The label roll is wound on the multiple sets of rollers 2, and the labels are guided to the label dispensing port by the distribution of the multiple sets of rollers 2 on the housing 1. The distribution of the multiple sets of rollers 2 can be planned according to the area of ​​the housing 1 and the distribution of other components on the housing 1, as long as it is ensured that the labels are dispensing from the label dispensing port.

[0035] Both the driving component and the label pressing component are mounted on the housing 1. The label pressing component is located near the label outlet, while the driving component is used to drive the label pressing component to press down the label dispensed from the label outlet so that the label can be pasted on the product surface.

[0036] To make more efficient use of the limited space on the housing 1, the drive assembly can be installed on the inside of the housing 1, while the label pressing assembly can be installed on the outside of the housing 1. An opening is provided on the housing 1, and the drive assembly and the label pressing assembly on the inside and outside of the housing 1 are linked by a linkage assembly that passes through the opening. This allows the drive assembly to drive the label pressing assembly to press down the label dispensed from the label outlet, thereby sticking the label to the product surface.

[0037] like Figure 3 As shown, the driving component in this embodiment includes an electromagnetic component 8 and a first connecting component 9. The electromagnetic component 8 is used to intermittently generate a magnetic field. When the electromagnetic component 8 is energized, a magnetic field is generated. When it is not energized, the magnetic field is not generated. The central control module controls the energization of the electromagnetic component 8 so that the electromagnetic field can intermittently generate a magnetic field according to a preset pattern. The intermittent magnetic field drives the first connecting component 9 to reciprocate.

[0038] A guide frame may be fitted over the first connector 9. The guide frame is fixed on the housing 1. A hollow guide channel is provided inside the guide frame for the first connector 9 to move. The guide frame restricts the position of the first connector 9, so that the first connector 9 moves laterally back and forth along the hollow guide channel under the action of a magnetic field.

[0039] The first connecting member 9 is linked with the label pressing assembly through a linkage component. The label pressing assembly is located near the label outlet and includes a fixed roller 3, a second connecting member 4, and a pressure roller 5. The shaft of the fixed roller 3 is fixed on the housing 1, and the second connecting member 4 is connected to the shaft of the fixed roller 3, so that the second connecting member 4 swings about the fixed roller 3 as an axis. The pressure roller 5 is installed at the other end of the second connecting member 4, and the pressure roller 5 can rotate along its own axis under the action of external force.

[0040] like Figure 1 , Figure 2 As shown, the second connector 4 has a bent structure. The end of the second connector 4 near the fixed roller 3 is in a horizontal state, and the end near the pressure roller 5 is inclined downward, so that the horizontal height of the pressure roller 5 is lower than the horizontal height of the fixed roller 3, so that the pressure roller 5 can press down and stick the label that has been marked.

[0041] The second connector 4 has a strip-shaped hole at one end for fixing the pressure roller 5. The pressure roller 5 can be detachably installed in the strip-shaped hole. The horizontal height of the pressure roller 5 can be adjusted through the strip-shaped hole, but it must always be ensured that the horizontal height of the pressure roller 5 is lower than the horizontal height of the fixed roller 3.

[0042] Below the label pressing assembly is a guide plate 6 and a clamp 7 fixed on the guide plate 6. The label, guided to the label dispensing port, passes through the clamp 7 and extends along the guide plate 6 to below the pressure roller 5, allowing the pressure roller 5 to directly press down on the already dispensed label, adhering it to the product surface. The clamp 7 and the label assembly work together to determine the label dispensing speed, dispensing time, and dispensing length. The guide plate 6 is designed with a downward tilt, guiding the label at a downward angle, reducing excessive bending of the label during pressing, maintaining label quality, and improving labeling efficiency.

[0043] The second connecting member 4 is linked to the first connecting member 9 via a linkage assembly, and the first connecting member 9 drives the pressure roller 5 to move longitudinally reciprocally at the label outlet. Figure 1 , Figure 3 As shown, the linkage component includes a third connector 11 and a fourth connector 12. The third connector 11 is configured as a T-shaped structure. The longitudinal end of the T-shape is connected to the first connector 9, and the transverse end of the T-shape is connected to the shaft on the housing 1. When the first connector 9 performs axial reciprocating motion, it can drive the third connector 11 to rotate along the shaft on the housing 1.

[0044] The fourth connector 12 passes through the opening in the housing 1. One end of the fourth connector 12 is connected to the third connector 11 on the inner side of the housing 1, and the other end is connected to the second connector 4 on the outer side of the housing 1. When the first connector 9 reciprocates, it drives the third connector 11 to rotate along the shaft. The fourth connector 12 synchronously drives the second connector 4 to swing, thereby realizing the pressing and lifting action of the pressure roller 5.

[0045] To accelerate the movement frequency of the pressure roller 5, an elastic element 10 is also connected to the third connecting member 11. The other end of the elastic element 10 is fixed to the housing 1, and the elastic element 10 is kept horizontal with the first connecting member 9, so that the movement of the third connecting member 11 can be quickly reset, and the pressure roller 5 can be quickly lifted to meet the labeling requirements under high speed.

[0046] The labeling machine described in this embodiment also includes a central control module. The central control module is connected to the label assembly and the drive assembly via signals. The central control module controls the label dispensing pattern of the label assembly and controls the magnetic supply pattern of the electromagnetic component 8 of the drive assembly according to the label dispensing pattern of the label assembly, so as to drive the label pressing assembly to perform repeated label pressing operations.

[0047] To accurately label the product, a positioning fiber optic cable 13 is provided on the side of the label dispensing port. The positioning fiber optic cable 13 is connected to the central control module. The positioning fiber optic cable 13 is used to detect whether the product is in position. When the central control module receives the positioning information detected by the positioning fiber optic cable 13, it immediately controls the labeling machine to dispense the label and simultaneously controls the drive assembly to drive the pressure roller 5 to press down the dispensed label and stick it on the product, thus completing the labeling operation.

[0048] In this embodiment, the labeling assembly is driven to move longitudinally and reciprocally by magnetic attraction. Under the action of the magnetic field, the movement direction of the first connecting piece 9 can be changed in a short time. This allows the pressure roller 5 to repeatedly perform pressing and lifting operations at high speed, thus adapting to high-speed labeling scenarios and replacing the traditional motor-driven method to complete the labeling operation, thereby improving the labeling efficiency of the labeling machine.

[0049] Example 2

[0050] This embodiment provides a labeling method for a labeling machine. This labeling method is applied to the labeling machine described in Embodiment 1. A conveyor line is located below the labeling machine for transporting products, allowing the products to move along the conveyor line to a position directly opposite the labeling machine. In this embodiment, the product to be labeled is named the target object. Figure 4 As shown, the labeling method specifically includes the following steps:

[0051] The system responds to high-speed labeling commands and controls the target object to be labeled to move forward continuously.

[0052] When a positioning message is received when the target object moves to the designated position, the labeling machine is controlled to dispense a partial label based on the positioning message, and the pressure roller 5 of the labeling machine is controlled to press down and stick the dispensed label to the target object; as the target object continues to move forward, the label pasted on the target object is completely pulled out of the labeling machine and completely pasted onto the surface of the target object.

[0053] The high-speed labeling command is generated based on the forward speed of the target object. In this embodiment, the forward speed of the transport line can be detected by a speed sensor to obtain the forward speed of the target object. When the forward speed of the target object is detected to be greater than a preset speed, the high-speed labeling command is generated.

[0054] When the detected forward speed of the target object is less than the preset speed, a low-speed labeling command is generated; where high speed generally refers to a speed of 80~250 meters / minute; while a speed of 0~80 meters / minute is considered a low-speed state.

[0055] When the target object moves forward at high speed, a high-speed labeling command is sent to the labeling machine to control the labeling machine to label in a high-speed labeling mode; if the target object moves forward at low speed, the labeling machine is controlled to label in a low-speed labeling mode.

[0056] The high-speed bidding method is as follows:

[0057] The labeling machine is controlled to dispense labels in a partial manner, and the pressure roller 5 of the labeling machine is controlled to press down the dispensed labels and stick them to the target object; as the target object continues to move forward, the labels pasted on the target object are completely pulled out of the labeling machine and completely pasted onto the surface of the target object.

[0058] Partial label dispensing refers to the labeling machine actively dispensing at least one-third of a complete label from the dispensing port, and then pressing the dispensed portion of the label down onto the target object surface to adhere it. At this point, the labeling machine stops actively dispensing labels; instead, it uses the moving target object to pull out the remaining two-thirds of the label from the dispensing port, and the pressing roller 5, which is in a downward pressing state, completely adheres the pulled-out label to the target object surface, completing one labeling operation. After completing one labeling operation, before waiting for the next target object to arrive, the pressing roller 5 is raised to its original height. When the next target object arrives, partial label dispensing is performed again, using a tearing method for labeling.

[0059] During partial label dispensing, the length of the label dispensed by the labeling machine must be related to the distance between the dispensing port and the pressure roller 5. The dispensing label length must be greater than or equal to the distance between the dispensing port and the pressure roller 5, so that the dispensed label can be located directly below the pressure roller 5 after partial label dispensing, allowing the pressure roller 5 to press down the dispensed label for affixing. Furthermore, the length of the dispensed label must be at least one-third of the total label length, extending the label to a position directly opposite the pressure roller 5 for labeling. This prevents the label from falling off during the tearing process due to an excessively short dispensing length, thus affecting the labeling quality.

[0060] In this embodiment, the labeling machine's label outlet is tilted towards the target object, causing the label to be dispensed at an inclined angle. This tilting at a certain angle allows for partial label dispensing. Combined with the relatively low-profile pressure roller 5, the downward pressing path of the pressure roller 5 can be further shortened, improving labeling efficiency.

[0061] When the target object is transported at high speed, the labeling machine partially dispenses the label and affixes it to the surface of the target object. As the target object moves forward at high speed, the label that is not fully dispensed is completely pulled out. Under the action of the pressure roller 5, the fully pulled-out label is completely affixed to the surface of the target object. This labeling method can be adapted to products transported at high speed, which greatly improves the labeling efficiency.

[0062] When the target object is transported at a low speed, a low-speed labeling command is generated. The labeling machine responds to the low-speed labeling command by adjusting its labeling mode to low-speed labeling mode. During the low-speed labeling process, the labeling machine does not perform partial labeling, but instead dispenses the complete label at the same speed as the target object's forward movement. The labeling machine dispenses the complete label at the same speed as the target object's forward movement, keeping the label and the target object synchronized. Then, the pressure roller 5 affixes the synchronized label to the surface of the target object, completing the synchronized labeling operation.

[0063] After each labeling operation is completed, the labeling machine collects the labeling signal, which is recorded in the form of a square wave. The labeling time can be determined by the labeling wavelength. The label size can be calculated by the labeling time and the labeling speed. The label size is compared with the labeling method of the current labeling machine. If the label size does not match the labeling method during the comparison, an alarm prompt is generated.

[0064] In this embodiment, the labeling method is switched according to the forward speed of the target object. In the high-speed state, only one-third of the label is dispensed, and the remaining label is pulled out by tearing to complete the labeling operation. In the low-speed state, the labeling machine continuously dispenses labels, and its dispensing speed is the same as the forward speed of the target object, so as to achieve a synchronous labeling effect.
