Description

Technical Field

[0001] The utility model relates to the technical field of new energy battery manufacturing, and particularly relates to a device and a system for pasting nameplates. Background Art

[0002] In the production and manufacturing process of new energy battery packs, nameplates are usually stamped on the surface of the battery packs to display information such as the corresponding models and technical parameters of the battery packs. However, since the side walls of the battery packs are generally thin, and the battery packs include components such as battery cells, management systems, and copper / aluminum busbars, if the method of riveting or bolting the nameplates on the products in other fields is adopted, brackets are generally welded on the outer wall, and the welds at the welding positions may penetrate the side walls, causing air leakage in the battery packs, which will further affect the waterproof and dustproof grades of the battery packs (generally IP67 / IP68). In addition, the welded brackets may also occupy more space. Therefore, the above riveting or bolting methods are generally not adopted for the nameplates of battery packs, and most of them will choose to paste the nameplates on the surface of the battery packs for fixation. However, at present, the pasting of the nameplates of battery packs generally still adopts the manual pasting method, which can be positioned by visual positioning, or by screen-printing nameplate position marks or positioning jigs, but only the pasting position of the nameplate can be controlled, and the pasting temperature and the cleanliness of the surface to be pasted cannot be quantitatively controlled. The initial adhesion of the nameplate will change with the change of personnel, environmental temperature, and the cleanliness of the surface to be pasted, and cannot be kept stable for a period of time. The insufficient initial adhesion of the nameplate is likely to further cause the nameplate to come off or fall off during use. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the technical problem that the pasting temperature and the cleanliness of the surface to be pasted cannot be controlled by manual visual pasting in the prior art, resulting in unstable pasting and causing the nameplate to come off or fall off, and to provide a device and a system for pasting nameplates.

[0004] In a first aspect, the utility model provides a device for pasting a nameplate, which includes a power source, a pressure head, and a cleanliness detector. The pressure head is connected to the output end of the power source. The pressure head is provided with a heating unit, a temperature sensor, and a vibration unit. The pressure head can be driven by the power source to approach or move away from the surface to be pasted. The heating unit is used to heat the nameplate and the surface to be pasted. The temperature sensor is used to detect the temperature of the nameplate and the surface to be pasted. The cleanliness detector is used to detect the cleanliness of the surface to be pasted. The vibration unit is used to drive the pressure head to vibrate.

[0005] Compared with the prior art, where manual pasting of nameplates can only control the pasting position but not quantitatively control the pasting temperature and the cleanliness of the surface to be pasted, which may lead to unstable pasting and easy occurrence of glue opening and falling off, the present application can use a heating unit to heat the nameplate and the surface to be pasted to improve the bonding performance. Since the bonding performance of the nameplate is affected by temperature, there is an optimal initial temperature value or temperature range that can keep the bonding performance of the nameplate in the best state. That is to say, when the nameplate and the surface to be pasted are at this temperature value or temperature range, the bonding performance of the nameplate can be significantly improved. Therefore, the present application can use a heating unit to heat the nameplate and the surface to be pasted, and a temperature sensor measures and feeds back the initial temperature parameters, and the heating temperature can be controlled by the heating unit to stabilize it at the preset initial temperature value or temperature range, so that the bonding performance of the nameplate can be kept in a better state; in addition, among the factors affecting the bonding performance of the nameplate, in addition to temperature, it is also related to the surface cleanliness of the surface to be pasted. Therefore, a cleanliness detector can be added to the device. The cleanliness detector can be fixed by a bracket. Before pasting, the cleanliness detector can be used to detect the cleanliness of the surface to be pasted. If the detection result meets the pasting standard, then the next pasting operation can be carried out. If the detection result does not meet the pasting standard, the surface to be pasted needs to be cleaned again until it meets the pasting standard before pasting; during the pasting process of the nameplate, a vibration unit can be used to further vibrate the pressing head, and vibration can be carried out after the temperature of the nameplate reaches the set value to accelerate the adhesion speed of the double-sided tape on the nameplate and make it reach the best bonding effect faster.

[0006] Preferably, it further includes a pressure sensor, and the pressure sensor is used to detect the pressure of the pressing head on the surface to be pasted.

[0007] Preferably, it further includes a bracket, and the cleanliness detector is fixedly connected to the power source through the bracket.

[0008] Preferably, the cleanliness detector is provided with a probe, and the probe is used to scan the surface to be pasted to detect the cleanliness.

[0009] Preferably, it further includes a locking mechanism provided in the pressing head. The locking mechanism includes at least two oppositely arranged clamping members and a transmission member connected to the clamping members. The nameplate can be placed between the oppositely arranged clamping members, and the clamping members can move towards or away from each other under the drive of the transmission member to clamp or loosen the nameplate.

[0010] Preferably, through holes are formed on the end surface of the pressing head for fixing the nameplate, and the through holes can be connected to a vacuum pumping device. The vacuum pumping device can apply or remove negative pressure through the through holes to fix or loosen the nameplate.

[0011] Preferably, a limiting member is further included. The pressing head and the limiting member are oppositely arranged and can be respectively located on the front and back sides of the surface to be pasted. The limiting member can keep the surface to be pasted fixed.

[0012] In a second aspect, the present utility model provides a system for pasting a nameplate, including the device for pasting a nameplate as described above; a control unit connected to the power source, the heating unit, the temperature sensor, and the pressure sensor respectively. The control unit can control the power source and the heating unit and receive the temperature and pressure data measured by the temperature sensor and the pressure sensor.

[0013] Preferably, a cleaning device is further included. The cleaning device is used to clean the surface to be pasted.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. The present utility model provides a device for pasting a nameplate. By fixing the nameplate on the pressing head and driving the pressing head to apply an adhesive pressure to the surface to be pasted through the power source, the pressure parameter can be measured and fed back by the pressure sensor, so that the initial pressure value during bonding can be controlled by the power source for the pressing head, thereby enabling the nameplate to be stable at a suitable initial pressure value and effectively improving its bonding performance. In addition, for the bonding performance of the nameplate, there is also an optimal initial temperature value or temperature range. That is to say, when the nameplate and the surface to be pasted are within this temperature value or temperature range, the bonding performance of the nameplate can be significantly improved. Therefore, the heating unit can also be used to heat the nameplate and the surface to be pasted to improve the bonding performance. Since the bonding performance of the nameplate is affected by temperature and there is an optimal initial temperature value or temperature range that can keep the bonding performance of the nameplate in the best state, that is to say, when the nameplate and the surface to be pasted are within this temperature value or temperature range, the bonding performance of the nameplate can be significantly improved. Therefore, in this application, the heating unit can be used to heat the nameplate and the surface to be pasted, and the initial temperature parameter can be measured and fed back by the temperature sensor. The heating temperature can be controlled by the heating unit to keep it stable within the preset initial temperature value or temperature range, thereby enabling the bonding performance of the nameplate to be kept in a better state. In addition, in addition to temperature, the factors affecting the bonding performance of the nameplate are also related to the surface cleanliness of the surface to be pasted. Therefore, a cleanliness detector can be added to the device. The cleanliness detector can be fixed by a bracket. Before pasting, the cleanliness detector can be used to detect the cleanliness of the surface to be pasted. If the detection result meets the pasting standard, the next pasting operation can be carried out. If the detection result does not meet the pasting standard, the surface to be pasted needs to be cleaned again until it meets the pasting standard before pasting. During the pasting process of the nameplate, the vibration unit can be used to further vibrate the pressing head. The vibration can be carried out after the temperature of the nameplate reaches the set value to accelerate the adhesion speed of the double-sided tape on the nameplate and make it reach the best bonding effect faster.

[0030] Example 1

[0031] This embodiment provides a device for pasting a nameplate.

[0032] Figure 1 It is a structural diagram of the first perspective (showing the battery pack) of the device for pasting a nameplate of the present utility model; Figure 2 It is a structural diagram of the second perspective (hiding the battery pack) of the device for pasting a nameplate of the present utility model; Figure 3 It is the first schematic diagram of the pressure head (installing the nameplate) of the device for pasting a nameplate of the present utility model; Figure 4 It is the second schematic diagram of the pressure head (without installing the nameplate) of the device for pasting a nameplate of the present utility model; Figure 5 It is a flowchart of the method for pasting a nameplate of the present utility model.

[0033] As Figures 1 to 4 shown, the device for pasting a nameplate described in this embodiment may include a power source 1 and a pressure head 2. The pressure head 2 is connected to the output end of the power source 1. The nameplate 6 can be fixed on the pressure head 2. The pressure head 2 may be provided with a heating unit, a temperature sensor 21 and a pressure sensor 22. The pressure head 2 can paste the nameplate 6 on the surface to be pasted under the drive of the power source 1. The heating unit can heat the nameplate 6 and the surface to be pasted. The temperature sensor 21 can detect the temperature of the nameplate 6 and the surface to be pasted. The pressure sensor 22 can detect the pressure of the pressure head 2 on the surface to be pasted; here, the device for pasting a nameplate described in this embodiment can generally paste the nameplate 6 on the battery pack 7. Therefore, the surface to be pasted can be considered as the outer wall surface of the battery pack 7. Of course, the object of pasting the nameplate 6 is not limited to the battery pack 7. By changing the shape of the pressure head 2, this device can also be used for the standardized pasting of other labels or products, and the surface to be pasted can also be the outer wall surface of other types of products. The present utility model does not make specific limitations on this.

[0034] Specifically, the power source 1 can be a servo motor. The pressure sensor 22 can be arranged between the indenter 2 and the power source 1. The heating unit can include a nameplate heater 23 and a substrate heater 24. The nameplate heater 23 is arranged at the position where the nameplate 6 is installed on the indenter 2. After the nameplate 6 is fixed on the indenter 2, the nameplate heater 23 can be covered, that is to say, the nameplate heater 23 can be in contact with the nameplate 6. When heating, the heat generated by the nameplate heater 23 can be directly transferred to the nameplate 6 for raising the temperature of the nameplate 6. The substrate heater 24 can be arranged at the position on the indenter 2 that is not covered by the nameplate 6. For example, when the nameplate 6 is installed on the indenter 2, the substrate heater 24 can be located around the nameplate 6. When the indenter 2 presses on the surface to be pasted, the substrate heater 24 can be in contact with the surface to be pasted. The heat generated by the substrate heater 24 can be directly transferred to the surface to be pasted, and the surface to be pasted and the substrate (such as the battery pack 7) to which the surface to be pasted belongs can be heated. The nameplate 6 and the surface to be pasted can be heated simultaneously by the nameplate heater 23 and the substrate heater 24, so that the temperatures of the nameplate 6 and the surface to be pasted are raised to a preset initial bonding temperature, and the bonding effect of the nameplate 6 can be improved. However, the present invention is not limited thereto. The power source 1 can also be of other types. For example, an air cylinder or a hydraulic cylinder or a manual screw rod can be used as the power source 1, and the target pressure value can be achieved through fluid pressure and stroke fine adjustment. The pressure sensor 22 can also be arranged at other positions on the indenter 2, and the installation position of the heater can also be selected according to needs. The present invention does not make specific limitations in this regard.

[0035] Optionally, the number of temperature sensors 21 can be 8. Four of the temperature sensors 21 can be installed at the installation position of the nameplate 6 on the indenter 2. When the nameplate 6 is installed on the indenter 2, the nameplate 6 can be in contact with these 4 temperature sensors 21. The 4 temperature sensors 21 can simultaneously detect the temperature parameters of the nameplate 6 and give real-time feedback. When heating with the nameplate heater 23, the heating process of the heater can be controlled in a timely manner according to the temperature data measured by the temperature sensors 21, so that the temperature of the nameplate 6 can be stabilized within a preset initial bonding temperature range. The other 4 temperature sensors 21 can be installed at the position on the indenter 2 that is not covered by the nameplate 6, such as the position of the substrate heater 24. These 4 temperature sensors 21 can be in contact with the surface to be pasted, and can measure the heating temperature of the substrate heater 24 on the surface to be pasted and give real-time feedback. When the substrate heater 24 is heating, the heating process of the heater can be controlled in a timely manner according to the temperature data measured by the temperature sensors 21, so that the temperature of the surface to be pasted can be stabilized within a preset initial bonding temperature range. However, the present invention is not limited thereto. The number and installation position of the temperature sensors 21 can also be adjusted and replaced according to actual needs, not limited to the above number and position. The present invention does not make specific limitations in this regard.

[0036] Compared with the prior art where the nameplate 6 can only be manually pasted to control the pasting position but cannot quantitatively control the pasting pressure and temperature, which may lead to unstable pasting and easy occurrence of glue opening and falling off, in this application, the nameplate 6 can be fixed on the pressing head 2, and the pressing head 2 is driven by the power source 1 to apply a bonding pressure to the surface to be pasted. The pressure parameter can be measured and fed back by the pressure sensor 22, so that the initial pressure value during bonding can be controlled by the power source 1 on the pressing head 2, thereby enabling the nameplate 6 to be stable at an appropriate initial pressure value and effectively improving its bonding performance. In addition, for the bonding performance of the nameplate 6, there is also an optimal initial temperature value or temperature range. That is to say, when the nameplate 6 and the surface to be pasted are within this temperature value or temperature range, the bonding performance of the nameplate 6 can be significantly improved. Therefore, a heating unit can also be used to heat the nameplate 6 and the surface to be pasted, and the initial temperature parameter is measured and fed back by the temperature sensor 21. The heating temperature can be controlled by the heating unit to keep it stable within the preset initial temperature value or temperature range, thereby enabling the bonding performance of the nameplate 6 to be maintained in a better state.

[0037] In this embodiment, the device for pasting the nameplate described in this embodiment may further include a bracket 3 and a cleanliness detector 4. The bracket 3 can be fixedly connected to the power source 1, and the cleanliness detector 4 can be fixedly installed on the bracket 3. The cleanliness detector 4 can be used to detect the cleanliness of the surface to be pasted.

[0038] In addition to the above-mentioned pressure and temperature, the factors affecting the bonding performance of the nameplate 6 are also related to the surface cleanliness of the surface to be pasted. Therefore, a cleanliness detector 4 can be added to the device. The cleanliness detector 4 can be fixed through the bracket 3. Before pasting, the cleanliness detector 4 can be used to detect the cleanliness of the surface to be pasted. If the detection result meets the pasting standard, the next pasting operation can be carried out. If the detection result does not meet the pasting standard, the surface to be pasted needs to be cleaned again until it meets the pasting standard and then pasted.

[0039] Optionally, the cleanliness detector 4 is provided with a probe, and the probe can be used to scan the surface to be pasted to detect the cleanliness.

[0040] For the cleanliness detection of the surface to be pasted, a probe device in the cleanliness detector 4 can be specifically used. The probe can detect the surface cleanliness by scanning and can feedback the measured cleanliness data to determine whether to perform the pasting operation. In the actual operation of cleanliness detection, the probe can be aligned with the pasting position of the nameplate 6 on the surface to be pasted. However, since the cleanliness detector 4 is fixedly installed in the device for pasting the nameplate and generally the position of the device itself is fixed and cannot be moved, the position of the surface to be pasted can be adjusted, that is, the position of the battery pack 7 can be adjusted to align the probe with the pasting position of the nameplate 6. However, the present invention is not limited thereto. If the position of the surface to be pasted (battery pack 7) is fixed and cannot be adjusted, the position of the cleanliness detector 4 can also be adjusted to align the probe with the pasting position of the nameplate 6, as long as the relative movement adjustment between the probe and the surface to be pasted can be achieved. The present invention does not make specific limitations on this.

[0041] Optionally, a vibration unit (not shown in the figure) can be provided in the pressing head 2, and the vibration unit can be used to vibrate the pressing head 2.

[0042] Specifically, the vibration unit can be integrally provided in the pressing head 2. During the pasting process of the nameplate 6, the vibration unit can be further used to vibrate the pressing head 2. The vibration can be performed after the temperature of the nameplate 6 reaches the set value to accelerate the adhesion speed of the double-sided tape on the nameplate 6 and make it reach the best bonding effect faster. The vibration frequency and vibration time of the vibration unit can be adjusted in real time, and the vibration frequency and vibration time of the vibration unit can be adjusted according to the size of different nameplates 6 and the characteristics of the adhesive to improve the bonding speed and effect of different nameplates 6.

[0043] It should be noted that the method for promoting the adhesion of the double-sided tape of the nameplate 6 can be the method of vibrating through the vibration unit as described above, or methods such as rolling pressure, pressure impact, overpressure, etc. The present invention does not make specific limitations on this.

[0044] In this embodiment, for the fixing method of the nameplate 6 on the pressing head 2, at least two specific fixing methods can be included. For example:

[0045] ① The device for pasting the nameplate described in this embodiment may further include a locking mechanism provided in the pressing head 2. The locking mechanism may include at least two oppositely arranged clamping members 25 and a transmission member 26 connected to the clamping members 25. The nameplate 6 can be placed between the oppositely arranged clamping members 25, and the clamping members 25 can move towards or away from each other under the drive of the transmission member 26 to clamp or release the nameplate 6.

[0046] In the manner shown in the attached drawings, for example, the locking mechanism may specifically include two oppositely arranged clamping members 25 and a transmission member 26 connected to the clamping members 25. For the fixing method of the nameplate 6 on the pressing head 2 before pasting, the locking mechanism can be used to clamp and fix or loosen the nameplate 6. Both the clamping members 25 and the transmission member 26 can be arranged in the pressing head 2. The distance between the two clamping members 25 on both sides can be adjusted by the transmission member 26. When fixing the nameplate 6, the distance between the clamping members 25 can be adjusted by the transmission member 26 to be greater than the size of the nameplate 6, then the nameplate 6 is placed between the clamping members 25 on both sides, and then the clamping members 25 are controlled to move towards each other until the nameplate 6 is clamped and fixed in the middle; after the nameplate 6 is pasted, the clamping members 25 can be controlled by the transmission member 26 to move in the opposite direction to loosen the nameplate 6, and thus the pressing head 2 can be separated from the nameplate 6.

[0047] ② At least one through hole (not shown in the figure) can be provided on the end face of the pressing head 2 for fixing the nameplate 6. The through hole can be connected to a vacuum pumping device, and the vacuum pumping device can apply or remove negative pressure through the through hole to fix or loosen the nameplate 6. Specifically, the number of through holes provided on the end face of the pressing head 2 for fixing the nameplate 6 can be selected and replaced according to actual needs, and the present utility model does not make specific limitations on this.

[0048] For the fixing method of the nameplate 6 on the pressing head 2 before pasting, a negative pressure adsorption method for the nameplate 6 can also be used as an alternative to the above locking mechanism. Specifically, a through hole can be provided on the end face of the pressing head 2 for fixing the nameplate 6, and the through hole is connected to a vacuum pumping device. When fixing the nameplate 6, the vacuum pumping device can be turned on to make the pressure in the through hole lower than the atmospheric pressure, thereby generating a pressure difference between the front and back sides of the nameplate 6, that is, the nameplate 6 can be adsorbed and fixed on the pressing head 2 through this negative pressure; after the nameplate 6 is pasted, the vacuum pumping device can be turned off, and the negative pressure acting on the nameplate 6 can be naturally removed, and thus the nameplate 6 can be separated from the pressing head 2.

[0049] It should be noted that for the fixing method of the nameplate 6 on the pressing head 2, other methods other than the above two methods can also be used, as long as it is convenient to realize the fixing and separation of the nameplate 6 on the pressing head 2, and the present utility model does not make specific limitations on this.

[0050] In this embodiment, the device for pasting the nameplate may further include a limiting member 5. The pressing head 2 and the limiting member 5 can be oppositely arranged, and the pressing head 2 and the limiting member 5 can be respectively located on the front and back sides of the surface to be pasted, and the limiting member 5 can keep the surface to be pasted fixed. Specifically, the limiting member 5 can be a limiting block, and the limiting block can abut against the other side of the object to which the surface to be pasted belongs for limiting.

[0051] Since the device for pasting the nameplate in the present application is usually used for pasting the nameplate 6 of the battery pack 7, that is to say, the surface to be pasted can be a side surface of the battery pack 7. When pasting, in order to keep the battery pack 7 stable under the pressure of the pressing head 2, it is necessary to set a limiting member 5 on the other side of the battery pack 7 opposite to the surface to be pasted for limiting. That is to say, the pressing head 2 and the limiting member 5 can be respectively arranged on the front and back sides of the surface to be pasted, and the limiting member 5 can be in contact with the battery pack 7 to prevent the battery pack 7 from moving during pasting. Similarly, for other objects that need to paste the nameplate 6, the pressing head 2 and the limiting member 5 can also be arranged on both sides of the object. Among them, the pressing head 2 can be aligned with the surface to be pasted on the object, and the limiting member 5 can be in contact with the other side of the object relative to the surface to be pasted. Similarly, the limiting member 5 can be used to play a limiting role.

[0052] As described above, the assembly line is fixed by the fixed seat to move and position the product to be pasted; it is also possible to customize the positioning tooling for the individual product by identifying the product characteristics and install this device on the tooling for use.

[0053] Embodiment 2

[0054] This embodiment provides a system for pasting a nameplate.

[0055] The system for pasting a nameplate described in this embodiment may include the device for pasting a nameplate as described in Embodiment 1.

[0056] As Figures 1 to 4 shown in, the system for pasting a nameplate described in this embodiment may further include a control unit (not shown in the figure) respectively connected to the power source 1, the heating unit, the temperature sensor 21 and the pressure sensor 22. The control unit can control the power source 1 and the heating unit and receive the temperature and pressure data measured by the temperature sensor 21 and the pressure sensor 22.

[0057] In this embodiment, for the system for pasting a nameplate, in addition to the above-mentioned device for pasting a nameplate, it may further include a control unit. The control unit can be connected to each element in the above-mentioned device for pasting a nameplate, so as to perform comprehensive control operations on each element in the above-mentioned device for pasting a nameplate according to the parameters measured by the sensors, and can realize the automatic control of the nameplate 6 pasting process.

[0058] Specifically, if the temperature data of the nameplate 6 feedback by the temperature sensor 21 is lower than the preset initial bonding temperature, the control unit will turn on the nameplate heater 23 to heat the nameplate 6 until the temperature of the nameplate 6 feedback by the temperature sensor 21 is equivalent to the preset initial bonding temperature. Then the control unit can adjust the power of the nameplate heater 23 downward to keep the temperature of the nameplate 6 stable near or within the preset initial bonding temperature range. If the temperature data of the nameplate 6 feedback by the temperature sensor 21 is higher than the preset initial bonding temperature, the control unit can adjust the power of the nameplate heater 23 downward or turn off the nameplate heater 23 to make the temperature of the nameplate 6 drop and finally stabilize near or within the preset initial bonding temperature range.

[0059] Similarly, for the pressure value of the indenter 2 feedback by the pressure sensor 22, it can also be adjusted by operating the power source 1 through the control unit to keep the pressure of the indenter 2 near the initial bonding pressure value or within the initial bonding pressure range.

[0060] Here, the system for pasting the nameplate described in this embodiment has parameter traceability. The control unit can record the pasting parameters of each battery pack and upload them to the production manufacturing system (such as MES). When the nameplate fails after-sales, various parameters during nameplate pasting can be traced to assist in analyzing the cause of failure and optimizing the parameter settings.

[0061] In this embodiment, the system for pasting the nameplate described in this embodiment may further include a cleaning device, and the cleaning device can be used to clean the surface to be pasted.

[0062] The structure and function of the device for pasting the nameplate described in this embodiment are completely the same as those of the device for pasting the nameplate described in Embodiment 1, and this embodiment will not be specifically described herein again.

[0063] Embodiment 3

[0064] This embodiment provides a method for pasting a nameplate.

[0065] The method for pasting the nameplate described in this embodiment can adopt the device for pasting the nameplate described in Embodiment 1 or the system for pasting the nameplate in Embodiment 2.

[0066] As Figures 1 to 5 shown, the method for pasting the nameplate described in this embodiment may include the following steps:

[0067] S1: Use a cleaning device to clean the surface to be pasted and use a cleanliness detector 4 to detect the cleanliness of the surface to be pasted. If the cleanliness of the surface to be pasted meets the standard, proceed to the following steps. If the cleanliness of the surface to be pasted does not meet the standard, clean and detect the surface to be pasted again until it meets the standard.

[0068] S2: Fix the nameplate 6 on the indenter 2 through the locking mechanism or negative pressure adsorption. Peel off the release paper on the nameplate 6. Drive the indenter 2 to move towards the surface to be pasted to paste the nameplate 6 by the power source 1. At the same time, detect the pressure value of the indenter 2 through the pressure sensor 22 to keep the indenter 2 at the set pressure;

[0069] S3: Start the heating unit to heat the nameplate 6 and the surface to be pasted. At the same time, detect the temperatures of the nameplate 6 and the surface to be pasted through the temperature sensor 21 to keep the nameplate 6 and the surface to be pasted at the set temperature.

[0070] S4: Start the vibration unit to vibrate the indenter 2 and the nameplate 6 at the set frequency to accelerate the adhesion of the double-sided tape on the nameplate 6.

[0071] S5: After the nameplate 6 is pasted, release the locking mechanism or remove the negative pressure to separate the nameplate 6 from the indenter 2. Operate the power source 1 to make the indenter 2 return to the initial position, and remove the pasted object (such as the battery pack 7) from the work station.

[0072] The above nameplate pasting method can realize highly automated control operations for pasting the nameplate 6, can measure parameters such as the pressure, temperature and surface cleanliness during pasting in real time, and make each measured parameter maintain in the most suitable range that can make the pasting performance reach the best effect through each component in the control device, avoiding technical defects such as the nameplate 6 coming unstuck and falling off to the greatest extent, and ensuring the stability of the nameplate 6 pasting.

[0073] In summary, the device for pasting nameplates of the present utility model can fix the nameplate on the pressure head and drive the pressure head to apply bonding pressure to the surface to be pasted through a power source. The pressure parameters can be measured and fed back by a pressure sensor, so that the initial pressure value during bonding can be controlled by the power source for the pressure head, thereby enabling the nameplate to be stabilized at an appropriate initial pressure value and effectively improving its bonding performance. In addition, for the bonding performance of the nameplate, there is also an optimal initial temperature value or temperature range. That is to say, when the nameplate and the surface to be pasted are within this temperature value or temperature range, the bonding performance of the nameplate can be significantly improved. Therefore, a heating unit can also be used to heat the nameplate and the surface to be pasted, and the initial temperature parameters are measured and fed back by a temperature sensor. The heating temperature can be controlled by the heating unit to stabilize it within a preset initial temperature value or temperature range, thereby enabling the bonding performance of the nameplate to be maintained in a better state. The system for pasting nameplates of the present utility model can be connected to each component in the above-mentioned device for pasting nameplates through a control unit, so that each component in the device for pasting nameplates can be comprehensively controlled and operated according to the parameters measured by the sensors, and automatic control of the nameplate pasting process can be achieved. The method for pasting nameplates of the present utility model can achieve highly automated control operations for nameplate pasting, can measure parameters such as the pressure, temperature, and surface cleanliness during pasting in real time, and can keep the parameters measured by each sensor within the most suitable range that can make the pasting performance reach the best effect through each component in the control device, maximizing the avoidance of technical defects such as the nameplate coming unstuck and falling off, and ensuring the stability of nameplate pasting.

[0074] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
