[0041] It should be noted that the embodiments and features of the embodiments in the present application can be combined with each other without conflict. The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0042] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should fall within the scope of protection of the present application.

[0043] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not necessarily limit to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0044] As introduced in the background, in the related art:

[0045] In the process of coating the bottom shell of a new energy battery pack, the glue breakage (local absence of glue joint) in the glue coating of the battery pack bottom shell is the main cause of sealing failure. The traditional glue breakage detection relies on manual visual inspection after coating, and the glue is repaired by manually holding a glue gun, which is time-consuming and labor-intensive. Alternatively, visual detection is used to repair the glue, but visual detection can only detect the plane and cannot accurately detect the glue thickness. The existing equipment can only indirectly judge the glue breakage through a flow meter (long response delay time), and cannot locate the breakpoint position.

[0046] To solve the above problems, the embodiments of the present application provide a glue coating control method, which solves the problems that the precursor signal (such as abnormal fluctuation of glue pressure) of glue breakage cannot be captured in real time, the glue breakage position is difficult to accurately locate, and the glue breakage cannot be automatically repaired after the glue breakage.

[0047] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0048] Figure 1 is a structural diagram of a glue coating control system according to the embodiments of the present application, Figure 2 is a flowchart of a glue coating control method, which comprises the following steps:

[0049] In step S100, the pressure value of the glue pipe is obtained by the first detection unit.

[0050] In step S200, the fluctuation entropy value of the pressure is determined according to the obtained continuous pressure value.

[0051] In step S300, if the fluctuation entropy value is greater than the preset entropy value, a first reminder information is sent out, and the glue breakage position is recorded, so that the glue repair operation is performed according to the glue breakage position; wherein the first reminder information is used to indicate that the glue breakage occurs.

[0052] The glue application control method in the application can be control of a glue application process of a battery pack bottom shell, can be glue application of a device of an electronic product such as a semiconductor, or can be glue application of a photovoltaic solar device, and the application is not limited to specific application products and application scenarios of glue application. In the application, glue in a glue pipe is used to apply glue to a product to be glued, the pressure value in the glue pipe is measured in real time, the fluctuation entropy value is determined through continuous pressure values, and whether the glue pipe is broken is determined through the size relationship between the fluctuation entropy value and the preset entropy value, and then whether the glue application process is broken is determined. It can be understood that the first detection unit 103 in the application can be a pressure sensor, which obtains the pressure value of the glue pipe 101 in real time, obtains continuous pressure values, that is, a pressure signal sequence, and determines the pressure change condition according to the continuous pressure values. It can be understood that in the field of condition monitoring and fault diagnosis, the fluctuation entropy value of pressure is an extremely valuable state indicator, which can reveal the deep dynamic characteristics of the system that cannot be reflected by traditional indicators (such as pressure mean value and effective value). The pressure change condition is determined by the fluctuation entropy value of pressure. Illustratively, the fluctuation entropy value of pressure in the application can be calculated by sample entropy, can be calculated by permutation entropy, can be calculated by fuzzy entropy, or can be calculated by information entropy, and the application does not limit the specific calculation method of the fluctuation entropy value. The preset entropy value is used to represent the fluctuation entropy value obtained by the continuous pressure value of the glue pipe under normal conditions. In some embodiments, the preset entropy value can be an upper limit value of the fluctuation entropy value of the normal pressure sequence. When the measured fluctuation entropy value of the glue pipe is greater than the preset entropy value, it is determined that the glue pipe is broken, the first reminder information of the broken glue is sent out, and the broken glue position is recorded to facilitate subsequent follow-up glue filling operation at the broken glue position. Of course, the first reminder information can be light reminder, can be sound reminder, or can be reminder by sending information to the terminal of the relevant personnel.

[0053] The application obtains the pressure of the glue pipe through the first detection device. The first detection device can measure the pressure value near the glue nozzle according to the glue nozzle position setting, and can better reflect the glue application condition on the product to be glued. The application can determine the fluctuation entropy value of the pressure through the continuous pressure values obtained by measuring the pressure of the glue pipe, and then determine whether the glue application process is broken, which can accurately predict the broken glue condition, improve the completeness of the glue application, and then improve the product quality.

[0054] Optionally, the method for recording the broken glue position comprises:

[0055] The first distance is obtained by the second detection unit; wherein the first distance is the distance from the second detection unit to the top of the glue after glue application or the distance from the second detection unit to the product to be glued;

[0056] If the first distance is greater than the preset distance, record the first detection position; if the first distance is less than or equal to the preset distance, record the second detection position.

[0057] The location of glue breakage is determined based on the first and second detection locations.

[0058] In this application, the second detection unit 104 can be a laser distance sensor or other type of distance-measuring sensor. The second detection unit is mounted on the hose, preferably at a certain horizontal distance from the hose, so as not to interfere with the hose's operation. (See reference...) Figure 1 As shown, the second detection unit can be mounted on the connecting sheet metal 102. Similarly, the pressure sensor in this application can be mounted on the hose. For example, it can be mounted on the hose at a certain distance from the nozzle, so as not to affect the operation of the hose. This application measures the distance between the position of the second detection unit and the target object below through the second detection unit. The target object can be the adhesive formed on the product after applying glue, or it can be the product to be glued (in the case of glue interruption, no adhesive is applied to the product to be glued). Of course, depending on the positional relationship between the glue hose and the product, the second detection unit can also measure the distance to the object in front, or it can measure the distance to the object behind. This application does not limit the positional relationship between the second detection unit and the object. That is, the second detection unit of this application is used to measure the distance between the second detection unit and the target object.

[0059] As the adhesive application process progresses, this application measures a first distance using a second detection unit and compares this first distance with a preset distance. The preset distance is the upper limit of the distance between the second detection unit and the top of the adhesive after application during normal application. This preset distance can be obtained experimentally. Of course, the preset distance will vary depending on the product being coated and the adhesive material. This application does not limit the specific value of the preset distance; those skilled in the art can set it according to actual needs. The first detection position in this application represents the detection position where adhesive breakage begins, and the second detection position represents the detection position where adhesive breakage is recovered. Specifically, if the first distance is greater than the preset distance, the first detection position is recorded; until the first distance is less than or equal to the preset distance, the second detection position is recorded. The first and second detection positions correspond to each other. The detection position is the location of the second detection unit. Based on the positional relationship between the second detection unit and the adhesive tube, the actual adhesive breakage position is determined. This application measures the adhesive breakage position of the adhesive tube using the second detection unit, enabling adhesive replenishment based on the measured position, achieving automatic processing after adhesive breakage, and improving processing efficiency and replenishment accuracy.

[0060] Optionally, the adhesive breakage location is determined based on the first detection location and the second detection location, including:

[0061] obtaining a second distance between the second detection unit and the hose;

[0062] determining a first real position according to the first detection position and the second distance;

[0063] determining a second real position according to the first detection position and the second distance;

[0064] determining a broken position according to the first real position and the second real position.

[0065] In the present application, the second detection unit can be installed on one side of the hose, and the second distance can be a horizontal distance. The real position is determined by the sum or difference of the first detection position and the second distance, i.e., the first real position is the position of the hose where the breaking starts, and the second real position is the position of the hose where the breaking is restored. The present application obtains the real position of the breaking through the second detection unit, so as to perform automatic glue filling operation, and improve the effect of glue coating and the speed of fault handling.

[0066] Optionally, the glue filling operation according to the broken position comprises:

[0067] In the case where the glue coating operation is completed, the hose is moved to the broken position, and the glue filling operation is performed;

[0068] In the case where the glue filling operation is completed, the broken position is cleared.

[0069] In the present application, when the breaking occurs, the broken position is recorded, so as to facilitate subsequent glue filling. After the glue filling is completed, the broken position is cleared, so as to facilitate subsequent glue coating and glue filling operations. The whole process does not need to be handled by an operator, and has high automation degree, high processing efficiency and good processing effect.

[0070] Optionally, the method further comprises:

[0071] obtaining an accumulated time length; wherein the accumulated time length is the time length elapsed since the last calculation of the fluctuation entropy value;

[0072] If the accumulated time length is greater than or equal to a preset time length, the accumulated time length is cleared, and the step of obtaining the pressure value of the hose by the first detection unit is returned, so as to re-perform pressure measurement and broken detection; wherein the preset time length is the time interval between two consecutive calculations of the fluctuation entropy value.

[0073] The application detects the pressure value of the glue pipe by periodic measurement, accumulates the control detection pressure value as the starting point, starts pressure measurement at the starting point, and obtains a preset number of pressure values until the fluctuation entropy value is calculated and the fluctuation entropy value in the measurement period is determined. The preset time length in the application is the pressure measurement period, and the specific value of the preset time length can be set according to actual needs. In some embodiments, the preset time length in the application can be set according to the historical occurrence of glue breaking, or can be set according to the glue coating demand, and the preset time length can be set by the person skilled in the art as needed. The application periodically measures the pressure to periodically detect the glue coating process, that is, to perform real-time detection of the glue coating process, and to alleviate the resource waste caused by uninterrupted pressure measurement, and to balance the detection demand and the detection resource.

[0074] Optionally, the method further comprises:

[0075] If the number of consecutive times that the fluctuation entropy value is greater than the preset entropy value is greater than or equal to the preset number of times, a second reminder information is sent out, and the glue coating operation is stopped; wherein the importance of the second reminder information is greater than the importance of the first reminder information.

[0076] The application judges the result of periodic pressure detection, the number of consecutive times is the number of consecutive fluctuation entropy calculation results greater than the preset entropy value, and the preset number of times is the upper limit value of the number of acceptable glue breaking. If the number of consecutive times is greater than the preset number of times, the current glue coating process is unacceptable, the glue coating operation is stopped, and a second reminder information is sent out. Of course, the application can highlight the importance of the second reminder information through color saturation, sound loudness, level of reminder information sending object, etc. to enable relevant personnel to timely handle the glue breaking fault.

[0077] Optionally, if the fluctuation entropy value is greater than the preset entropy value, the method further comprises:

[0078] Detecting the normal pressure value of the glue pipe under the condition that the glue pipe normally discharges glue and coats glue;

[0079] According to a plurality of consecutive normal pressure values, a plurality of normal fluctuation entropy values are determined, and the upper limit value of the plurality of normal fluctuation entropy values is taken as the preset entropy value.

[0080] In order to achieve the above-mentioned purpose, according to another aspect of the application, a glue coating control device is provided, comprising:

[0081] The glue pipe is used for coating glue on the product to be coated;

[0082] The first detection unit is arranged on the glue pipe and is used for measuring the pressure value of the glue pipe;

[0083] The control unit is connected with the first detection unit to determine a fluctuation entropy value according to the continuous pressure values, and further to send a first reminding information and record the position of the broken glue in the case that the fluctuation entropy value is greater than a preset entropy value; wherein the first reminding information is used to represent the occurrence of the broken glue.

[0084] Optionally, the glue application control device further comprises:

[0085] The second detection unit is associated with the glue pipe to measure a first distance; wherein the first distance is a distance from the second detection unit to the top of the glued glue body or a distance from the second detection unit to the product to be glued;

[0086] The control unit is connected with the second detection unit to determine the position of the broken glue in the case that the first distance is greater than a preset distance.

[0087] According to another aspect of the present application, a battery is provided, and the bottom shell of the battery is glued by the glue application control device and the glue application control method as described above.

[0088] In order to enable those skilled in the art to more clearly understand the technical solutions of the present application, reference will be made to the accompanying drawings Figure 3 The implementation process of the glue application control method of the present application will be described in detail below in combination with specific embodiments.

[0089] In order to solve the problems in the related art, the pressure in the glue pipe is detected by using the method of high-frequency sampling of the pressure of the glue pipe, if the pressure fluctuation entropy value > threshold value, the risk of blockage is warned (3-5 seconds earlier than the broken glue), the laser displacement sensor is installed in front of the glue pipe, the distance is detected to detect whether there is glue leakage, and the position of the broken point is marked, the mechanical arm carries the glue gun to automatically return to the broken point to perform spiral glue filling, which can improve the coverage rate of the glue, save the time of manual glue filling, and improve the production efficiency.

[0090] A pressure sensor (i.e., the first detection unit of the present application) is installed at a distance of ≤200 mm from the glue nozzle of the glue gun, for real-time monitoring of the pressure value of the glue pipe. When the fluctuation entropy value of the pressure is greater than the set threshold value (i.e., the preset entropy value), a glue breakage warning (i.e., the first reminder information) is given. A laser displacement sensor (i.e., the second detection unit) is installed in front of the glue pipe, and a distance detection mode is started. When the detected distance (i.e., the first distance) is greater than the set distance value (i.e., the preset distance), the position of the breakpoint is marked. Until the detection distance is equal to the set distance, the position of the end point is marked. The mechanical arm completes the entire glue coating process, carries the glue gun to the marked position, and automatically performs glue replenishment. Through the above operation, the time for manual glue replenishment is saved, and the production efficiency is improved. The glue nozzle of the glue gun refers to the distance of the pressure sensor from the glue nozzle. In the above example, 200 mm is based on the size of the pressure sensor to avoid interference; those skilled in the art can adjust the distance as needed. The fluctuation entropy value is the pressure sequence in a period of time, which is analyzed by the information entropy calculation method to obtain the numerical value.

[0091] The present application adopts data acquisition of fluid pressure sensor and laser displacement sensor, cooperates with the control system of the equipment, and can give real-time warning for the pain points of battery pack bottom shell glue coating and glue breaking in the new energy field, and can automatically replenish glue at the glue coating and glue breaking position, save manual glue replenishment operation, and improve production quality.

[0092] First, the entropy fluctuation of the equipment during normal glue coating is collected, and the pressure entropy value of the normal glue coating of the glue coating machine is measured. Assuming that the entropy value of the normal glue coating fluctuation is 0.2-0.5, in some embodiments, the preset entropy value of the present application can be set to the upper limit value 0.5 of the measured value. If the measured value, i.e., the fluctuation entropy value, is greater than 0.5, a glue breakage abnormal warning is given, and the control system of the equipment is also synchronized. It can also be uploaded to the MES system and record the number of faults. If the equipment finishes coating the entire battery pack bottom shell and still gives a glue breakage abnormal warning (exemplarily, if the entropy value is measured periodically, i.e., after each measurement, an abnormal warning is given), the mechanical arm returns to the initial position, and a first-level stop alarm (i.e., the second reminder information) is given, the equipment is stopped, and the personnel is prompted to check the glue coating equipment system, check the glue barrel, structural valve and other elements, and timely troubleshoot the equipment failure.

[0093] Exemplarily, if the glue used for glue coating is mixed glue, the mixed ratio needs to be calculated to set the preset entropy value.

[0094] Second, install a laser displacement sensor (i.e. the second detection unit) in front of the glue pipe, first use a normal battery pack coated with glue to obtain standard parameters, open the distance detection mode, collect the distance X between the height of the glue body (i.e. the top of the glue body after coating) and the sensor after normal coating, when the normal coating mode is entered, the distance detection mode is opened, when the laser displacement sensor detects the distance Y>X, the coordinates P1(A1, B1, C1, i.e. the first detection position) of the point are recorded, until the laser displacement sensor detects the distance Y=X, record P2(A2, B2, C2, i.e. the second detection position), assuming that the horizontal distance between the glue gun and the displacement sensor is N (i.e. the second distance), then after the mechanical arm completes the entire battery pack bottom shell coating process, it carries the glue gun to the position of coordinates P(A1-N, B1, C1) to Q(A2-N, B2, C2), and performs automatic glue filling operation along the original coating track.

[0095] In the coating process, the glue pipe and the laser displacement sensor move with the coating position on the placement surface of the product to be coated. The height of the glue body here is the height (length) of the coated glue. In robot coating, the Z axis is constant, i.e. the height of the glue nozzle and the glue strip is constant (assuming X). If the glue is broken, i.e. the battery pack bottom shell has no glue strip (glue body), the distance Y is the distance from the glue nozzle to the bottom of the battery pack (i.e. the product to be measured), at this time Y>X.

[0096] Finally, after the recorded coordinate points are all filled with glue, the mechanical arm returns to the initial position, uploads the glue filling times to the control system of the equipment, records the glue filling times and glue filling time of the equipment, and deletes the recorded coordinate point record, waits for the next equipment coating operation.

[0097] It should be noted that the above is an example and does not specifically limit the implementation logic.
