Description

Control method for colloid coating equipment and colloid coating equipment Technical Field

[0001] The present disclosure relates to the technical field of colloid coating, and in particular to a control method for colloid coating equipment and the colloid coating equipment. Background Art

[0002] Colloid coating is the process of covering a fluid such as glue on a product by dotting, pouring, or painting. The colloid coating process is a common step in the production process of various industries. Taking the production of power batteries as an example, in order to dissipate the large amount of heat generated during the use of the power battery, the power battery is often fixedly connected to the cooling structure in surface contact, and the heat of the power battery is dissipated by heat conduction so that the battery can be maintained at a suitable operating temperature. The processing process usually involves first coating the surface of the power battery with colloid, and then attaching the cooling structure to the surface of the glue-coated box of the power battery. The quality of the colloid coating will affect the subsequent heat dissipation effect of the battery. As the production process moves towards digitalization and intelligence, it is hoped that the degree of automation of the colloid coating process can be improved while still ensuring the quality of the colloid coating, such as glue coating accuracy and / or reliability.

[0003] However, some of the related colloid coating technologies still rely on manual operation and are difficult to achieve high automation, while others, although partially automated, cannot ensure the quality of colloid coating.

[0004] Summary of the Invention

[0005] In view of the above problems, the present disclosure provides a control method for a colloid coating device and a colloid coating device to improve the quality of automated colloid coating.

[0006] In a first aspect, the present disclosure provides a control method for a colloid coating device, wherein the colloid coating device includes a glue discharging module, a first moving mechanism and a test module, and the control method includes: performing a test inspection operation, including: moving the glue head in the glue discharging module to a first position aligned with the test module through the first moving mechanism, instructing the glue discharging module to discharge colloid from the glue head with a first glue amount, receiving a second glue amount from the test module, wherein the second glue amount is obtained based on the measurement of the colloid received by the test module by the test module, and determining that the test inspection of the colloid coating device has passed when the deviation of the second glue amount relative to the first glue amount does not exceed a first threshold value.

[0007] In the technical solution of the embodiments of the present application, the glue dispensing module is controlled to discharge a first amount of glue from the glue head to the testing module, and the testing module receives a second amount of glue measured on the received glue. If the deviation of the second amount of glue from the first amount of glue does not exceed a first threshold, the test inspection of the glue coating equipment is determined to have passed. In this way, the glue coating equipment can be controlled to automatically complete first-article inspection, thereby improving the efficiency of first-article inspection and reducing labor costs. In this way, while improving production efficiency and reducing labor costs, the frequency of first-article inspection can be adaptively adjusted according to actual conditions, thereby improving the accuracy of the glue amount discharged during the automated glue coating process and, in turn, improving the quality of the automated glue coating.

[0008] In some embodiments, the test operation is performed upon detecting that a first criterion has been met, wherein the first criterion includes at least one of the following: initial startup of the colloid coating apparatus; a first predetermined time period has elapsed since the last execution of the test operation; and a change in the type of product to be coated. By performing the test operation upon detecting that the first criterion has been met, the accuracy of the amount of colloid discharged during the automated colloid coating process can be further improved, thereby further improving the quality of the automated colloid coating process.

[0009] In some embodiments, the control method further includes obtaining information regarding a change in the type of the product to be coated from the first remote control system. In actual production lines, information regarding the product to be coated is often recorded in a remote inventory management system or production line process control system, rather than locally in the colloid coating equipment. Obtaining information regarding changes in the type of the product to be coated from the remote control system can reduce the need for manual verification of product type changes that would require manipulation of the colloid coating equipment.

[0010] In some embodiments, the first glue quantity is determined based on the size of the glue head. The first glue quantity is flexibly adjusted based on the glue head size, rather than being a fixed value. This allows the glue dispensing module to complete the dispensing of the first glue quantity in a shorter time, regardless of the glue head size. This reduces the time required to perform testing and inspection operations, improves testing and inspection efficiency, and ultimately increases production efficiency.

[0011] In some embodiments, the glue dispensing module includes a metering module configured to meter the glue delivered to the glue head. The control method further includes: in response to the metering module determining that the first glue quantity has been discharged, instructing the testing module to measure the received glue to obtain the second glue quantity. This ensures that the testing module measures the received glue only after the first glue quantity has been completely discharged, thereby obtaining a more accurate second glue quantity.

[0012] In some embodiments, the test module is configured to: detect whether the first amount of glue has been discharged; and in response to detecting that the first amount of glue has been discharged, perform the measurement on the received glue to obtain the second amount of glue. In this way, the test module can autonomously measure the received glue to obtain the second amount of glue without requiring external control, thereby reducing signaling interactions.

[0013] In some embodiments, the control method further includes: in response to determining that the test passes: moving the glue head from an initial position to a glue application starting position of the product to be glued by the first moving mechanism; and driving the glue head to move along a trajectory by the first moving mechanism, and instructing the glue dispensing module to discharge glue from the glue head at a third glue amount to apply glue to the product to be glued. In this way, automated glue application of the product to be glued can be achieved.

[0014] In some embodiments, the glue dispensing module further includes a metering module configured to meter the glue delivered to the glue head. The control method further includes: determining a fourth glue amount of the glue delivered to the glue head during glue coating of the product to be coated with glue based on the measurement of the metering module; and instructing the glue dispensing module to stop coating the next product to be coated with glue if the fourth glue amount deviates from the third glue amount by more than a second threshold. In this way, the quality of the glue coating process can be automatically controlled, reducing the error costs caused by poor glue coating quality.

[0015] In some embodiments, the control method further includes uploading the fourth glue quantity to a second remote control system. Uploading the fourth glue quantity to the second remote control system facilitates subsequent traceability of product production data and helps production personnel remotely view production data.

[0016] In some embodiments, the control method further includes obtaining the third glue quantity from a third remote control system based on the type of the product to be coated. For example, production personnel may pre-set a correspondence between product type and glue quantity in the remote control system. Obtaining glue quantity information corresponding to the product type from the remote control system can reduce the need for on-site verification by manual de-colloidation and coating equipment.

[0017] In some embodiments, the control method further includes: after the colloid coating is completed, moving the colloid head back to the initial position via the first moving mechanism. In this way, the colloid head can be prevented from colliding with the product due to remaining in the gluing position, thereby improving the reliability of the colloid coating device and the product.

[0018] In some embodiments, the control method further includes: after the colloid coating is completed, instructing the second moving mechanism to transport the colloid-coated product away from the gluing location. This reduces the possibility of collision between the glue head and the product, thereby improving the reliability of the colloid coating equipment and the product. Furthermore, the gluing station can be quickly and automatically freed up, eliminating the need for manual handling, reducing the time the colloid coating equipment must wait for the next product to be coated, and improving operational continuity.

[0019] In some embodiments, the control method further includes: before the first moving mechanism moves the glue head from the initial position to the glue application starting position, instructing the second moving mechanism to move the product to be glued to the glue application position. This is conducive to achieving streamlined production of products.

[0020] In some embodiments, the control method further includes: in response to determining that the product to be glued has reached the gluing position, acquiring an image of the product to be glued using an image acquisition device; and determining the gluing starting position based on the image. By acquiring a real image of the product that has reached the gluing position using the image acquisition device, the gluing starting position can be more accurately determined, thereby improving gluing accuracy.

[0021] In some embodiments, the colloid coating apparatus further includes a colloid waste module, and the control method further includes: executing a colloid waste operation, including: moving the adhesive head to a second position aligned with the colloid waste module via the first moving mechanism; and instructing the adhesive dispensing module to discharge colloid from the adhesive head at a fifth adhesive amount. In this manner, the colloid coating apparatus can be controlled to automatically discharge waste colloid without manual operation, thereby reducing labor costs.

[0022] In some embodiments, the colloid discarding operation is performed when a second criterion is detected, wherein the second criterion includes the colloid not being discharged from the colloid head within a second preset time period. This can reduce the possibility of the colloid head being clogged due to colloid solidification, thereby improving the reliability of the colloid coating device.

[0023] In some embodiments, the fifth glue amount is associated with the duration of time the glue head has not discharged glue since the last time it discharged glue. Rather than being a fixed value, the fifth glue amount is flexibly adjusted based on the duration of time the glue head has not discharged glue since the last time it discharged glue. This can further reduce the possibility of glue head clogging due to glue solidification, thereby improving the reliability of the glue coating equipment.

[0024] In a second aspect, the present disclosure provides a control method for a colloid coating device, the colloid coating device comprising a gluing module and a first moving mechanism, the method comprising: in response to determining that a product to be coated has reached a gluing position, acquiring a first image of the product to be coated via an image acquisition device; determining, based on the first image and size information, a plurality of coordinates defining a region to be coated on the product to be coated, the plurality of coordinates comprising a first starting point coordinate and a first ending point coordinate in a first direction, and a second starting point coordinate and a second ending point coordinate in a second direction; moving, via the first moving mechanism, a glue head in the gluing module from an initial position to a gluing starting position of the product to be coated, wherein the gluing starting position is determined based on the first starting point coordinate and the second starting point coordinate; and driving, via the first moving mechanism, the glue head to move along a trajectory to a gluing ending position, and instructing the gluing module to discharge glue from the glue head at a preset glue amount to coat the product to be coated with glue, wherein the gluing ending position is determined based on the first starting point coordinate and the second ending point coordinate. In this manner, the glue head can be controlled by the first moving mechanism to accurately move along the trajectory from the gluing starting position to the gluing ending position. In this way, the degree of automation and quality of colloid coating can be improved.

[0025] In some embodiments, the control method further includes: after the colloid coating is completed, acquiring a second image of the colloid-coated product through the image acquisition device; determining a first colloid-coated area based on the second image; and, if the first area is smaller than a second area required to be coated on the product, instructing the glue dispensing module to continue discharging colloid from the glue head to apply additional colloid coating to the product. In this way, if the colloid-coated area does not meet the requirement, the product can be promptly supplemented with colloid coating.

[0026] In some embodiments, the first moving mechanism drives the adhesive head to move along the trajectory at a first speed, where the first speed is determined based on a second speed, where the second speed is the speed at which the adhesive dispensing module discharges the adhesive from the adhesive head at the predetermined adhesive amount. By linking the adhesive head movement speed with the adhesive dispensing speed, the predetermined adhesive amount can be more accurately discharged, thereby meeting the quality requirements of the adhesive coating.

[0027] In some embodiments, the area to be glued belongs to the first surface of the product to be glued, and the size information includes first information and second information, the first information represents the distance between the boundary of the area to be glued and the boundary of the first surface, and the second information represents the size of the glue head.

[0028] In some embodiments, the area to be glued includes multiple sub-areas, where adjacent sub-areas are separated by openings on the first surface, and the size information further includes third information indicating the size and position of the openings. Thus, even if the surface of the product to be glued contains openings, the glue application trajectory can still be accurately calculated.

[0029] In a third aspect, the present disclosure provides a colloid coating device, comprising: a glue discharging module, including a glue head, the glue discharging module being used to discharge colloid through the glue head; a first moving mechanism being used to move the glue head of the glue discharging module to a specified position; a testing module being used to receive colloid and measure the colloid; and a control module being communicatively coupled to the glue discharging module, the first moving mechanism and the testing module, and being used to execute program instructions to execute the control method described in any one of the embodiments of the above-mentioned first aspect.

[0030] In a fourth aspect, the present disclosure provides a colloid coating device, comprising: a glue discharging module, including a glue head, the glue discharging module being used to discharge colloid through the glue head; a first moving mechanism being used to move the glue head of the glue discharging module to a specified position; and a control module being communicatively coupled to the glue discharging module and the first moving mechanism, and being used to execute program instructions to execute the control method described in any one of the embodiments of the above-mentioned second aspect.

[0040] The following detailed description of the embodiments of the present disclosure is provided in conjunction with the accompanying drawings and examples. The detailed description of the following embodiments and the accompanying drawings are used to illustrate the principles of the present disclosure, but are not intended to limit the scope of the present disclosure, that is, the present disclosure is not limited to the described embodiments.

[0042] The directional words appearing in the following description are all directions shown in the figures and do not limit the specific structure of the present disclosure. In the description of the present disclosure, it should also be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to the specific circumstances.

[0043] Analysis shows that one of the reasons for the low quality of automated colloid coating in related technologies is the inaccurate amount of colloid discharged during the automated colloid coating process. Some related technologies use manual first-article inspection to improve the accuracy of the discharged colloid amount.

[0044] However, this manual first-article inspection method is inefficient and labor-intensive. To improve production efficiency and reduce labor costs, first-article inspections are conducted less frequently. This results in the accuracy of the amount of adhesive discharged during the automated adhesive coating process fluctuating over time. Even if an inaccurate amount of adhesive is present, it can go undetected, impacting the quality of the automated adhesive coating process.

[0045] In view of this, the present disclosure proposes a control method for a colloid coating device, which can control the colloid coating device to automatically perform first article inspection.

[0046] Compared to manual first-article inspection, this method can improve the efficiency of first-article inspection and reduce labor costs, thereby increasing the frequency of first-article inspection while improving production efficiency and reducing labor costs. In this way, the accuracy of the amount of colloid discharged during the automated colloid coating process can be improved, thereby improving the quality of automated colloid coating.

[0047] For ease of understanding, the colloid coating equipment of some embodiments of the present disclosure will first be described.

[0048] FIG1 is a schematic structural diagram of a colloid coating device according to some embodiments of the present disclosure.

[0049] 1 , a colloid coating device 100 includes a glue dispensing module 101 . The glue dispensing module 101 includes at least a glue head 105 . The glue dispensing module 101 is used to discharge the colloid via the glue head 105 .

[0050] The glue coating device 100 further includes a first moving mechanism 102. The first moving mechanism 102 is used to move the glue head 105 in the glue dispensing module 102 to a designated position.

[0051] In some embodiments, the first moving mechanism 102 may be a robot that can hold the adhesive head and move the adhesive head to a designated position.

[0052] The colloid coating device 100 further includes a testing module 103. The testing module 103 is used to receive the colloid and measure the colloid.

[0053] In some embodiments, the testing module 103 may include a container (eg, a plastic box) for accommodating the received colloid. In some implementations, the testing module 103 may further include a device for weighing the container to measure the received colloid.

[0054] In some embodiments, the glue head 105 can store a certain amount of colloid and discharge it. In other embodiments, the glue discharging module 101 includes a separate colloid supply module 106, which provides colloid to the glue head via a colloid delivery device (not shown in Figure 1). The colloid delivery device may include a hose. The colloid supply module 106 may include a container (e.g., a barrel-shaped container) for storing the colloid. The colloid supply module 106 may also include a pump for delivering the colloid.

[0055] As some implementations, the colloid supply module 106 may further include a stirrer for stirring the colloid to be delivered to the colloid head 105 to remove air from the colloid.

[0056] In some embodiments, the glue dispensing module 101 may further include a metering module 107. Metering module 107 may be used to meter the colloid delivered to the glue head. As an example, metering module 107 may be disposed between the colloid supply module 106 and the glue head 105, as shown in FIG1 , and fluidically connected to both via a colloid delivery device. If the glue head 105 itself stores and discharges the colloid, metering module 107 may also be disposed within the glue head 105, as opposed to FIG1 .

[0057] The colloid coating device 100 may further include a control module 104. The control module 104 is used to communicate with other modules in the colloid coating device 100 to control other modules to perform corresponding operations. The operations performed by the control module 104 will be described in more detail below.

[0058] As some implementations, the control module 104 may be a programmable logic controller (PLC).

[0059] It should be understood that integrating the control module 104 into the colloid coating apparatus 100 is only one implementation manner. In some other implementation manners, the control module 104 may also be independent of the colloid coating apparatus 100 .

[0060] The colloid coating device 100 further includes a colloid waste module 108. The colloid waste module 108 is configured to receive the colloid. For example, the colloid waste module 108 may also include a container for containing the colloid.

[0061] It is understood that the colloid coating apparatus 100 shown in FIG1 is exemplary and non-limiting. The colloid coating apparatus of the present disclosure may include one or more modules in the colloid coating apparatus 100 .

[0062] It is also understood that the colloid coating apparatus disclosed in the embodiments of the present disclosure can be used, but is not limited to, for colloid coating of batteries. Batteries can include, but are not limited to, battery cells, battery modules, battery packs, etc. The battery pack can include, but is not limited to, the lower case of the battery pack.

[0063] So far, the colloid coating device of the present disclosure has been briefly described. Next, the control method of the colloid coating device of some embodiments of the present disclosure will be described with reference to FIG. 2 to FIG. 5 .

[0064] 2 is a flow chart of a control method for a colloid coating device according to some embodiments of the present disclosure. The colloid coating device comprises at least the glue dispensing module 101, the first moving mechanism 102 and the testing module 103 shown in FIG1.

[0065] As shown in FIG2 , the control method for a colloid coating device includes step 202 . In step 202 , a test and inspection operation is performed. Step 202 includes steps 2022 to 2028 .

[0066] In step 2022, the glue head in the glue dispensing module is moved to a first position aligned with the testing module by a first moving mechanism.

[0067] For example, the test module may include a container for accommodating the colloid, with an opening provided above the container. In this case, the colloid head may be moved to the position just above the opening of the container in the test module (i.e., the first position) by the first moving mechanism.

[0068] In step 2024 , the glue dispensing module is instructed to discharge glue from the glue head in a first glue amount.

[0069] For example, the glue discharged from the glue head is received by a container in the test module.

[0070] In step 2026, a second glue amount is received from the test module. The second glue amount is obtained based on a measurement of the glue received by the test module by the test module.

[0071] In some implementations, the test module is configured to detect whether a first amount of adhesive has been discharged, and in response to detecting that the first amount of adhesive has been discharged, measure the received adhesive to obtain a second amount of adhesive. In this way, the test module can autonomously measure the received adhesive to obtain the second amount of adhesive without requiring external control, thereby reducing signaling interactions.

[0072] In other implementations, in response to the metering module determining that the first amount of glue has been discharged, the testing module is instructed to measure the received glue to obtain a second amount of glue. This ensures that the testing module measures the received glue only after the first amount of glue has been completely discharged, thereby obtaining a more accurate second amount of glue.

[0073] As some implementations, the second glue quantity may be uploaded to a remote control system, such as a Total Order Management (TOM) system or a Manufacturing Execution System (MES).

[0074] At step 2028 , if the deviation of the second glue amount relative to the first glue amount does not exceed the first threshold, it is determined that the test inspection of the glue coating device has passed.

[0075] The deviation of the second glue amount from the first glue amount does not exceed the first threshold value, indicating that the difference between the glue amount expected to be discharged by the glue dispensing module and the actual glue amount discharged is small. In other words, the glue amount discharged by the glue coating apparatus is highly accurate. In this case, the test inspection of the glue coating apparatus is determined to have passed.

[0076] In some implementations, the first threshold is set to be small enough to ensure that the accuracy of the amount of glue discharged by the glue coating device that has passed the test is high enough.

[0077] As some implementations, when the deviation of the second glue amount relative to the first glue amount exceeds a first threshold, an alarm may be issued, in which case production personnel may be promptly notified to inspect and maintain the glue coating equipment.

[0078] In the above embodiment, the glue dispensing module is controlled to discharge glue from the glue head to the testing module at a first glue amount, and the testing module receives a second glue amount obtained by measuring the received glue. If the deviation of the second glue amount from the first glue amount does not exceed a first threshold, the glue coating equipment is determined to have passed the test inspection. In this manner, the glue coating equipment can be controlled to automatically complete first-article inspection, thereby improving the efficiency of first-article inspection and reducing labor costs. This improves production efficiency and reduces labor costs while adaptively adjusting the frequency of first-article inspection according to actual conditions. This improves the accuracy of the glue amount discharged during the automated glue coating process, thereby improving the quality of the automated glue coating process.

[0079] The control method for the colloid coating device shown in FIG. 2 will be further described below with reference to some embodiments.

[0080] In some embodiments, step 202 may be executed when it is detected that the first criterion is met, ie, a test verification operation is performed.

[0081] As some implementations, the first criterion may be an initial startup of the colloid coating device. That is, in these implementations, the colloid coating device performs a test and inspection operation each time it is initially started.

[0082] As some other implementations, the first criterion may be that a first preset time has passed since the last test and inspection operation was performed. That is, in these implementations, a test and inspection operation is performed every time the first preset time has passed.

[0083] As some other implementations, the first criterion may be a change in the type of the product to be glued. That is, in these implementations, a test and inspection operation is performed each time the type of the product to be glued changes.

[0084] In the above embodiment, by performing the test and inspection operation when it is detected that the first standard is met, the accuracy of the amount of colloid discharged during the automated colloid coating process can be further improved, thereby further improving the quality of the automated colloid coating.

[0085] In some embodiments, information about a change in the type of product to be glued can be obtained from the first remote control system, so that a test operation can be performed when the information about the change in the type of product to be glued is obtained. The first remote control system can be, for example, a TOM system or an MES.

[0086] In actual production lines, information about the products being coated is often recorded in remote inventory management systems or production process control systems, rather than locally at the adhesive coating equipment. By obtaining information about changes in the type of product being coated from the remote control system, the need to manually verify product type changes and manipulate the adhesive coating equipment can be reduced.

[0087] As some implementations, the first remote control system may automatically send information about the change in the type of the product to be glued when the type of the product to be glued changes.

[0088] In other implementations, the first remote control system may transmit information regarding a change in the type of the product to be coated in response to a user operation. For example, the first remote control system may include a human-computer interaction module. When the type of the product to be coated changes, the user may perform a user operation based on the human-computer interaction module to cause the first remote control system to transmit information regarding the change in the type of the product to be coated.

[0089] In some embodiments, the first glue amount of the glue discharge module to be instructed to discharge glue from the glue head in step 2024 is determined according to the size of the glue head.

[0090] For example, the first glue amount is positively correlated with the size of the glue head. That is, the larger the glue head is, the larger the first glue amount is; conversely, the smaller the glue head is, the smaller the first glue amount is.

[0091] The first glue quantity is flexibly adjusted based on the size of the glue tip, rather than being a fixed value. This allows the glue dispensing module to quickly discharge the first glue quantity, regardless of the glue tip size. This reduces the time required for testing and inspection operations, improves testing and inspection efficiency, and ultimately increases production efficiency.

[0092] 3 is a flow chart of a control method for a colloid coating device according to some other embodiments of the present disclosure. The colloid coating device at least includes the glue dispensing module 101 and the first moving mechanism 102 shown in FIG1 .

[0093] As shown in FIG3 , the control method for the colloid coating device includes steps 302 to 304 .

[0094] In step 302, the glue head in the glue dispensing module is moved from an initial position to a glue application starting position of the product to be glued by a first moving mechanism.

[0095] In some embodiments, in response to determining that the product to be glued has reached the gluing position, an image capture device can be used to capture an image of the product to be glued, and the gluing starting position can be determined based on the image. The implementation of image-based determination of the gluing starting position can be found in the control method described below with reference to FIG. 5 and will not be described in detail here. By capturing a real-world image of the product that has reached the gluing position using the image capture device, the gluing starting position can be more accurately determined, improving gluing accuracy.

[0096] As some implementations, the image acquisition device may be mounted on the first moving mechanism to conveniently capture images of the product to be glued.

[0097] In step 304 , the glue head is driven to move along the track by the first moving mechanism, and the glue dispensing module is instructed to discharge glue from the glue head at a third glue amount so as to coat the glue on the product to be coated.

[0098] It should be understood that the amounts of the third glue corresponding to different types of products to be glued may be the same or different.

[0099] In some implementations, the third glue amounts corresponding to different types of products to be glued are pre-stored in a remote control system, such as a TOM system or MES. In this case, the third glue amount corresponding to the current product to be glued can be obtained from the remote control system to execute step 304.

[0100] In the above embodiment, the glue head can be moved from an initial position to a starting position for gluing the product to be coated by controlling the first moving mechanism. After the glue head reaches the starting position, the glue head is moved along a trajectory by controlling the first moving mechanism, and the glue dispensing module is controlled to discharge glue from the glue head at a third glue volume. This allows for automated glue coating of the product to be coated.

[0101] The control method shown in FIG3 is further described below with reference to some embodiments.

[0102] In some embodiments, the control method shown in FIG3 is executed in response to determining that the test has passed. The manner of determining that the test has passed may be the manner shown in FIG2 .

[0103] Specifically, the colloid coating equipment is controlled to apply colloid to the product to be coated only if the test results are satisfactory. Furthermore, the colloid coating equipment is controlled to apply colloid to the product to be coated only if the amount of colloid discharged by the colloid coating equipment is confirmed to be accurate. This further improves the quality of automated colloid coating.

[0104] In the aforementioned embodiments, although the adhesive coating is performed only on the product to be coated after the test passes (i.e., the adhesive amount discharged by the adhesive coating device is confirmed to be accurate), it should be noted that the adhesive coating device may still discharge an inaccurate amount of adhesive due to wear during use. In view of this, the present disclosure further provides the following embodiments.

[0105] In some embodiments, the fourth glue amount of the glue delivered to the glue head during the glue coating of the product to be coated can also be determined based on the measurement of the metering module, and when the deviation of the fourth glue amount relative to the third glue amount exceeds a second threshold, the glue output module is instructed to stop continuing to coat the next product to be coated with glue.

[0106] The third glue amount may represent the desired glue amount applied to the product, while the fourth glue amount may represent the actual glue amount applied to the product. If the fourth glue amount deviates from the third glue amount by more than a second threshold, this indicates a significant discrepancy between the desired glue amount applied to the product and the actual glue amount applied. In this case, the glue dispensing module is instructed to stop applying glue to the next product to be coated.

[0107] In the above embodiment, the accuracy of the amount of glue discharged by the glue coating equipment during product coating is verified based on the deviation between the third and fourth glue amounts. If the deviation of the fourth glue amount from the third glue amount exceeds a second threshold, the glue dispensing module is instructed to stop coating the next product. This allows for automated quality control of the glue coating process, reducing the cost of errors caused by poor glue coating quality.

[0108] In some implementations, the second threshold is set to be small enough to ensure that the deviation between the amount of glue expected to be applied to the product and the amount of glue actually applied is smaller.

[0109] As some implementations, when the fourth glue amount deviates from the third glue amount by more than a second threshold, an alarm may be issued, in which case the production personnel may be promptly notified to inspect and maintain the glue coating equipment.

[0110] In some embodiments, the fourth glue quantity may also be uploaded to a second remote control system. The second remote control system may be the same as or different from the first remote control system. The second remote control system may be, for example, a TOM system or an MES system.

[0111] The fourth glue quantity is the actual amount of glue delivered to the glue head, as measured by the metering module. Uploading this fourth glue quantity to the second remote control system facilitates subsequent traceability of product production data and allows production personnel to remotely view production data.

[0112] In some embodiments, a third glue quantity can be obtained from a third remote control system based on the type of product to be glued. The third remote control system can be the same as or different from the first remote control system. The third remote control system can be, for example, a TOM system or an MES system.

[0113] For example, the type of the product to be glued can be determined based on information obtained from the first remote control system regarding a change in the type of the product to be glued. Then, based on the type of the product to be glued, a corresponding third glue amount can be obtained from the third remote control system to instruct the glue dispensing module to discharge glue from the glue head at the third glue amount.

[0114] For example, production personnel can pre-set the correspondence between product type and glue quantity in the remote control system.

[0115] By obtaining information on the amount of glue corresponding to the product type from the remote control system, the necessity of on-site verification by manual de-colloidation coating equipment can be reduced.

[0116] In some embodiments, after the colloid coating is completed, the first moving mechanism moves the adhesive head back to the initial position, thereby preventing the adhesive head from colliding with the product due to remaining in the adhesive coating position, thereby improving the reliability of the colloid coating device and the product.

[0117] In some embodiments, before the glue head is transported from the initial position to the gluing start position by the first moving mechanism, the second moving mechanism may be instructed to transport the product to be glued to the gluing position.

[0118] After the second moving mechanism has transported the product to be glued to the gluing position, the first moving mechanism is used to transport the glue head from the initial position to the gluing starting position. This reduces the possibility of the glue head colliding with the product to be glued, thereby improving the reliability of the glue coating equipment and the product.

[0119] In other embodiments, after the colloid coating is completed, the second moving mechanism can be instructed to transport the colloid-coated product away from the coating location. This reduces the possibility of collision between the glue head and the product, thereby improving the reliability of the colloid coating equipment and the product. Furthermore, the colloid coating station can be quickly and automatically freed up, eliminating the need for manual handling. This reduces the time the colloid coating equipment has to wait for the next product to be coated, thereby improving operational continuity.

[0120] In some other embodiments, before the first moving mechanism moves the glue head from the initial position to the glue application starting position, the second moving mechanism is instructed to move the product to be glued to the glue application position. Furthermore, after the glue application is completed, the second moving mechanism is further instructed to move the glue-coated product away from the glue application position. This facilitates streamlined production of products.

[0121] In some implementations, the second mobile mechanism may be an automated guided vehicle (AGV). The AGV may have a lifting structure, and the product may be placed on the lifting structure.

[0122] 4 is a flow chart of a control method for a colloid coating device according to some other embodiments of the present disclosure. The colloid coating device comprises at least the glue discharging module 101, the first moving mechanism 102 and the colloid waste module 108 shown in FIG1 .

[0123] As shown in FIG4 , the control method for a colloid coating device includes step 402 . In step 402 , a colloid waste operation is performed. Step 402 includes steps 4022 to 4024 .

[0124] In step 4022, the glue head in the glue dispensing module is moved to a second position aligned with the glue waste module by a first moving mechanism.

[0125] For example, the colloid waste module may include a container for accommodating the colloid, with an opening provided above the container. In this case, the colloid head may be moved to the position just above the opening of the container in the colloid waste module (i.e., the second position) by the first moving mechanism.

[0126] In step 4024 , the glue dispensing module is instructed to discharge glue from the glue head in a fifth glue amount.

[0127] For example, the colloid discharged from the colloid treatment unit is received by a container in the colloid waste module.

[0128] As some implementations, when the sizes of the glue heads are different, the fifth glue amount is different.

[0129] In the above embodiment, after the first moving mechanism moves the adhesive head to the second position aligned with the adhesive waste module, the adhesive dispensing module is instructed to discharge adhesive from the adhesive head at the fifth adhesive quantity. In this manner, the adhesive coating apparatus can be controlled to automatically discharge the waste adhesive without manual operation, thereby reducing labor costs.

[0130] The control method for the colloid coating device shown in FIG. 4 will be further described below with reference to some embodiments.

[0131] In some embodiments, the colloid discarding operation may be performed when it is detected that a second criterion is met. The second criterion may include that the colloid is not discharged from the colloid head within a second preset time period.

[0132] That is, when the colloid is not discharged from the colloid head within the second preset time period, the colloid discarding operation is performed so that the colloid is discharged from the colloid head to the colloid discarding module.

[0133] The adhesive head is prone to clogging due to solidification of the colloid if it has not been discharged for a certain period of time. By controlling the discharge of the colloid from the adhesive head to the colloid disposal module upon detecting that the colloid has not been discharged from the adhesive head within a second preset period of time, the possibility of clogging of the adhesive head due to solidification of the colloid can be reduced, thereby improving the reliability of the colloid coating equipment.

[0134] In some embodiments, the fifth glue amount is associated with a duration in which no glue is discharged since the glue head last discharged glue.

[0135] For example, the fifth glue amount is positively correlated with the duration of time the glue head has not discharged glue since the last time it discharged glue. That is, the longer the duration of time the glue head has not discharged glue since the last time it discharged glue, the larger the fifth glue amount; conversely, the shorter the duration of time the glue head has not discharged glue since the last time it discharged glue, the smaller the fifth glue amount.

[0136] The fifth glue amount is flexibly adjusted based on the duration of time the glue head has not discharged glue since the last time it was discharged, rather than a fixed value. This can further reduce the possibility of glue head clogging due to glue solidification, thereby improving the reliability of the glue coating equipment.

[0137] 5 is a flow chart of a control method for a colloid coating device according to some other embodiments of the present disclosure. The colloid coating device comprises at least the glue dispensing module 101 and the first moving mechanism 102 shown in FIG1 .

[0138] As shown in FIG. 5 , the control method for the colloid coating device includes steps 502 to 508 .

[0139] In step 502 , in response to determining that the product to be glued has reached the gluing position, a first image of the product to be glued is acquired by an image acquisition device.

[0140] As some implementations, the product to be glued is transported to the gluing position by a second moving mechanism.

[0141] In step 504 , a plurality of coordinates defining an area to be glued of the product to be glued are determined based on the first image and the size information.

[0142] Here, the plurality of coordinates include first start point coordinates and first end point coordinates in the first direction, and second start point coordinates and second end point coordinates in the second direction.

[0143] For example, when the area to be glued is rectangular, the first direction and the second direction are respectively an X direction and a Y direction perpendicular to each other.

[0144] In step 506, the glue head in the glue dispensing module is moved from the initial position to the glue application starting position of the product to be glued by the first moving mechanism.

[0145] Here, the gluing starting position is determined according to the first starting point coordinates and the second starting point coordinates.

[0146] In step 508 , the first moving mechanism drives the glue head to move along the trajectory to the glue coating end position, and instructs the glue dispensing module to discharge glue from the glue head in a preset glue amount to coat the product with glue.

[0147] Here, the gluing end position is determined according to the first starting point coordinates and the second end point coordinates.

[0148] For example, if the area to be glued is rectangular, the starting position for glue application can be a point near a vertex of the area to be glued, as determined by the first starting point coordinates and the second starting point coordinates. Furthermore, the ending position for glue application can be a point near another vertex of the area to be glued, as determined by the first starting point coordinates and the second ending point coordinates. The line connecting the starting and ending positions for glue application is an edge of the area to be glued.

[0149] In the above embodiment, based on the first image and size information of the product to be glued at the gluing position, multiple coordinates defining the gluing area of ​​the product to be glued are determined. Based on these coordinates, the first movement mechanism can then accurately control the glue head to move along a trajectory from the gluing starting position to the gluing ending position. This improves the automation and quality of glue coating.

[0150] The control method for the colloid coating device shown in FIG5 will be further described below with reference to some embodiments.

[0151] In some embodiments, after the colloid coating is completed, a second image of the colloid-coated product is captured by an image acquisition device. Based on the second image, a first area of ​​the colloid coating is determined. If the first area is smaller than a second area of ​​the product to be coated, the glue dispensing module is instructed to continue dispensing colloid from the glue head to apply additional colloid coating to the product.

[0152] In this way, when the colloid-coated area does not meet the requirements, the product can be supplemented with colloid coating in time.

[0153] In some embodiments, in step 508, the first moving mechanism drives the glue head to move along the trajectory at a first speed. Here, the first speed is determined based on a second speed, which is the speed at which the glue dispensing module discharges the glue from the glue head at a preset glue amount in step 508.

[0154] By associating the glue head movement speed with the glue discharge speed, the preset glue amount can be discharged more accurately to meet the quality requirements of the glue coating.

[0155] As some implementations, the first speed is positively correlated with the second speed.

[0156] For example, the relationship between the first velocity V1 and the second velocity V2 can be expressed by the following formula: V1 / V2=L×S×ρ / m, where L is the total length of the track coated by the colloid, S is the area coated by the colloid, ρ is the density of the colloid, and m is the weight of the colloid.

[0157] In some embodiments, the area to be glued is a first surface of the product to be glued. In this case, the size information in step 504 may include first information and second information. The first information represents the distance between the boundary of the area to be glued and the boundary of the first surface. The second information represents the size of the glue tip.

[0158] In some implementations, the area to be glued may include multiple sub-areas, where adjacent sub-areas are separated by an opening on the first surface. In this case, the dimensional information may further include third information indicating the size and position of the opening. This allows accurate calculation of the glue application trajectory even when the surface of the product to be glued contains an opening.

[0159] For ease of understanding, some implementations of step 504 are described below in conjunction with Figure 6. Figure 6 is a schematic diagram of a first image according to some embodiments of the present disclosure.

[0160] As shown in Figure 6, the first image includes a first surface S1 of the product to be glued. The first surface S1 has an opening O, which divides the area to be glued into sub-areas A1 and A2.

[0161] The outer side of the first surface S1 is an auxiliary positioning structure F. The auxiliary positioning structure F is provided with a plurality of hole-shaped structures M for auxiliary positioning.

[0162] In this case, the first information in the size information represents the distances Dx1, Dx2, Dy1 and Dy2 between the boundary of the area to be glued and the boundary of the first surface S1 of the product to be glued defined by the auxiliary positioning structure F.

[0163] The second information in the size information represents the size of the glue head, and the size of the glue head can be used to determine the coating width W during the glue coating process.

[0164] The third information in the size information indicates the size of the opening O and the position of the opening O on the first surface S1 .

[0165] In the example shown in FIG6 , the first starting point coordinate X1 and the first ending point coordinate X2 in the first direction can be determined based on the first image and the distances Dx1 and Dx2 in the first information of the size information. Furthermore, the second starting point coordinate Y1 and the second ending point coordinate Y2 in the second direction can be determined based on the first image and the distances Dy1 and Dy2 in the first information of the size information.

[0166] After determining the above-mentioned multiple coordinates, the gluing starting position P1 of the product to be glued can be determined according to the first starting point coordinate X1 and the second starting point coordinate Y1, and the gluing ending position P2 of the product to be glued can be determined according to the first starting point coordinate X1 and the second end point coordinate Y2.

[0167] Exemplarily, the coordinates of the gluing start position P1 and the gluing end position P2 in the first direction are both equal to the first starting point coordinate X1. The coordinates of the gluing start position P1 in the second direction are determined based on the second starting point coordinate Y1 and the smearing width W, for example, equal to Y1 plus W / 2. The coordinates of the gluing end position P2 in the second direction are determined based on the second ending point coordinate Y2 and the smearing width W, for example, equal to Y2 minus W / 2.

[0168] In this way, the gluing start position P1 and the gluing end position P2 can be accurately determined.

[0169] After determining the gluing starting position P1, the first moving mechanism can be used to move the glue head from the initial position to the gluing starting position P1 of the product to be glued. Thereafter, the first moving mechanism drives the glue head to move along a trajectory (i.e., the multiple arrowed lines in the gluing area shown in FIG6 ) to the gluing ending position P2.

[0170] The control method shown in FIG5 may also include other embodiments, and the relevant parts may refer to the embodiment of the control method shown in FIG2 , which will not be described in detail here.

[0171] It should be understood that the control methods for colloid coating equipment in the above-mentioned embodiments may be arbitrarily combined. For example, the control method for colloid coating equipment may include the processes shown in Figures 2 and 3 above; or, for another example, the control method for colloid coating equipment may include the processes shown in Figures 3 and 4 above. This is not an exhaustive list.

[0172] The present disclosure further provides a control module for a colloid coating device, which may be, for example, the control module 104 shown in FIG1 .

[0173] In some embodiments, the control module for the colloid coating device includes a unit for executing the control method for the colloid coating device of any one of the above embodiments.

[0174] In other embodiments, a control module for a colloid coating device includes a memory and a processor coupled to the memory, and the processor is configured to execute the control method for a colloid coating device of any of the above embodiments based on instructions stored in the memory.

[0175] The memory may include, for example, a system memory, a fixed non-volatile storage medium, etc. The system memory may store, for example, an operating system, an application program, a boot loader, and other programs.

[0176] The control module may also include input / output interfaces, a network interface, and a storage interface. These interfaces, as well as the memory and processor, may be connected via a bus, for example. The input / output interfaces provide connections for input / output devices such as displays, mice, keyboards, and touch screens. The network interface provides connections for various networked devices. The storage interface provides connections for external storage devices such as SD cards and USB flash drives.

[0177] As some implementations, the control module for the colloid coating device in any of the above embodiments may be a PLC.

[0178] The present disclosure further provides a colloid coating device, comprising at least one module of the colloid coating device 100 shown in FIG. 1 , and a control module for the colloid coating device according to any one of the above embodiments.

[0179] The operation flow of the colloid coating equipment of these embodiments will be described below with reference to Figure 7. Figure 7 is a schematic diagram of the operation flow of the colloid coating equipment according to some embodiments of the present disclosure.

[0180] As shown in FIG. 7 , the operation flow of the colloid coating device includes steps 702 to 722 .

[0181] In step 702 , the control module detects that a first criterion is met.

[0182] For example, the first criterion is the initial startup of the colloid coating device. For another example, the first criterion is the first preset time period that has passed since the last detection that the first criterion was met. For another example, the first criterion is a change in the type of the product to be coated.

[0183] In step 704 , when it is detected that the first standard is met, the control module moves the glue head in the glue dispensing module to a first position aligned with the testing module through the first moving mechanism.

[0184] In step 706 , after the glue head moves to a first position aligned with the test module, the glue dispensing module is instructed to discharge glue from the glue head in a first glue amount.

[0185] In step 708 , the testing module measures the received glue to obtain a second glue amount.

[0186] In some implementations, upon determining that the glue dispensing module has discharged the first amount of glue, the test module is instructed to measure the received glue. In other implementations, upon detecting that the first amount of glue has been discharged, the test module automatically measures the received glue.

[0187] In step 710 , the control module receives the second glue amount measured by the measurement module.

[0188] At step 712 , the control module determines that the test inspection of the glue coating apparatus passes because the deviation of the second glue amount relative to the first glue amount does not exceed a first threshold.

[0189] By executing steps 702 to 712 , the colloid coating equipment can automatically complete the first article inspection.

[0190] In step 714 , the control module moves the glue head from the initial position to the glue application starting position of the product to be glued by using the first moving mechanism.

[0191] As some implementations, step 714 may be performed in response to step 712 .

[0192] As another implementation, the starting position of gluing can be determined according to the embodiment related to FIG. 5 .

[0193] In step 716a, the control module drives the rubber head to move along the track via the first moving mechanism.

[0194] For example, the control module can drive the glue head to move from the glue application starting position P1 to the glue application ending position P2 according to the trajectory shown in FIG. 6 through the first moving mechanism.

[0195] In step 716b, the control module instructs the glue dispensing module to discharge glue from the glue head in a third glue amount while the first moving mechanism drives the glue head to move along the trajectory, so as to apply glue to the product to be glued.

[0196] By executing step 714 , step 716 a and step 716 b , the colloid coating device can automatically coat the product to be coated with colloid.

[0197] In step 718 , the control module detects that the second criterion is met.

[0198] For example, the second criterion may be that the glue is not discharged from the glue head within a second preset time period.

[0199] In step 720 , when it is detected that the second criterion is met, the control module moves the glue head to a second position aligned with the glue waste module through the first moving mechanism.

[0200] In step 722 , after the glue head moves to the second position aligned with the glue waste module, the control module instructs the glue dispensing module to discharge glue from the glue head in a fifth glue amount.

[0201] By executing steps 718 to 722 , the colloid coating device can automatically discharge waste colloid.

[0202] It will be understood that the operational flow shown in FIG7 is merely illustrative and non-restrictive. For example, the order in which the steps are performed need not necessarily follow the order shown in FIG7 . For another example, the operational flow of the colloid coating device may include only one or more of the steps shown in FIG7 . For another example, the operational flow of the colloid coating device may also include steps other than those shown in FIG7 . For relevant details, please refer to the embodiments related to FIG7 , which will not be described in detail here.
