The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0042] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation on the automatic film laminating machine for aluminum profiles, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0043] like Figure 1 As shown, the memory 1005 as a storage medium may include an operating system, a data storage module, a network communication module, a user interface module and an aluminum profile automatic film splicing control program.

[0044] exist Figure 1 In the automatic aluminum profile laminating machine shown, the network interface 1004 is mainly used for data communication with other devices; the interactive device 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the automatic aluminum profile laminating machine of the present invention can be set in the automatic aluminum profile laminating machine, and the automatic aluminum profile laminating machine calls the automatic aluminum profile film splicing control program stored in the memory 1005 through the processor 1001, and executes the automatic aluminum profile film splicing control method provided by the embodiment of the present invention.

[0045] The embodiment of the present invention provides an automatic film splicing control method for aluminum profiles, referring to Figure 2 , Figure 2 The figure is a flow chart of a first embodiment of an automatic film splicing control method for aluminum profiles according to the present invention.

[0046] In this embodiment, the aluminum profile automatic film splicing control method includes:

[0047] Step S1, obtaining first status information of a first film roll and obtaining second status information of a second film roll, wherein the first film roll is a film roll in use at the current moment and the second film roll is a spare film roll at the current moment;

[0048] Optionally, the methods for obtaining the first status information of the first film roll and the second status information of the second film roll may be different. Specifically, since the first film roll is the roll in use, it is necessary to accurately monitor the current usage of the roll in use, while for the second film roll, it is only necessary to determine whether the second film roll exists. Therefore, the first status information and the second status information may be different types of data. Optionally, in some embodiments, the first film roll and the second film roll may be equipped with the same type of detection sensor. By setting different sampling rates, high-frequency detection of the first film roll can be achieved while effectively reducing the resources required to detect the second film roll.

[0049] Step S2: When the first status information indicates that the film roll is insufficient and the second status information indicates that a second film roll exists, stopping film lamination and controlling the spare film corresponding to the second film roll to be laminated with the used film corresponding to the first film roll;

[0050] Specifically, optionally, the first status information is determined by the number of revolutions of the film roll. Preferably, the first status information can be determined by the thickness, volume, etc. of the film roll. The film application here specifically refers to suspending the film application on the aluminum profile. Of course, other metal materials that are more susceptible to oxidation can also be applied during the production process. Generally speaking, the purpose of pausing film application is to prevent the spare film corresponding to the second film roll from being pulled and broken during the application process.

[0051] Step S3: When the standby film and the in-use film are completely attached, the connection between the first film roll and the in-use film is cut off, and the film attaching task is performed.

[0052] In this embodiment, when the backup film is detected to have been bonded to the current film, the connection between the first film roll and the current film is severed, and the film bonding task is performed. After the backup film and the current film are bonded, the bonded portion of the backup film and the current film is connected to both the first and second film rolls, increasing the thickness of the bonded portion. However, this increased thickness does not actually affect the protective effect of the bonded aluminum profile. Furthermore, the protective film needs to be removed during actual use, and the increased thickness of the protective film in a small area does not affect its actual effectiveness.

[0053] In this embodiment, by obtaining the first status information of the first film roll and the second status information of the second film roll, when the first status information is that the film roll is insufficient and the second status information is that the second film roll exists, the film laminating is stopped, and the spare film corresponding to the second film roll is controlled to be laminated with the in-use film corresponding to the first film roll; compared with the existing automatic film laminating machine that needs to wait for employees to replace the film roll, the automatic film laminating machine can realize automatic replacement of the film roll, thereby effectively reducing the time used for replacing the film roll, and when the spare film and the in-use film are completed, the connection between the first film roll and the in-use film is cut off, and the film laminating task is performed. Compared with the existing automatic film laminating machine, the operating state of the automatic film laminating machine can be restored in time, thereby improving the efficiency of film laminating.

[0054] Further, based on the first embodiment, a second embodiment of the aluminum profile automatic film splicing control method of the present invention is proposed. In this embodiment, referring to Figure 3 , the step of obtaining the first status information of the first film roll includes:

[0055] Step S11, controlling the laser distance measuring device to measure a first distance from a preset position to the first film roll;

[0056] It should be noted that the laser distance measuring device here emits the laser toward the center of the first film roll, and is perpendicular to the outer or inner surface of the first film roll that has adhesive force. The laser distance measuring device is fixed, and the preset position corresponds to the position of the laser distance measuring device. The laser distance measuring device transmits a laser beam to the first film roll, receives the reflected laser signal, and measures the time from the laser emission to the return signal. The first distance to the first film roll is calculated based on the product of the speed of light and time.

[0057] Step S12, calculating the thickness of the first film roll according to the first distance and a preset distance between the laser distance measuring device and a fixing post of the first film roll;

[0058] The first film roll is typically mounted on a circular fixed post. When the automatic film laminating machine pulls the protective film, the first film roll rotates so that the protective film can be adaptively unfolded as needed. Simultaneously, as the first film roll rotates, its thickness decreases. The thickness of the first film roll is calculated using the first distance and the preset distance between the laser distance measuring device and the fixed post of the first film roll, accurately determining the remaining amount of protective film on the first film roll. The thickness of the first film roll is calculated by subtracting the first distance from the preset distance.

[0059] Step S13: determining the first state information according to the thickness of the first film roll.

[0060] In this embodiment, when the thickness of the first film roll is less than a preset thickness, the first status information is determined to be insufficient film roll; when the thickness of the first film roll is greater than or equal to the preset thickness, the first status information is determined to be sufficient film roll; specifically, insufficient film roll here refers to insufficient remaining length of the protective film on the film roll. Sufficient film roll here refers to sufficient remaining length of the protective film on the film roll. In addition, the first film roll generally includes a roll core, so the preset thickness here needs to be set to be greater than the thickness of the roll core. In other embodiments, a camera can also be set to detect the thickness of the first film roll to determine the first status information. The length of the protective film on the first film roll can also be determined by counting the number of rotations of the first film roll.

[0061] In this embodiment, a laser distance measuring device is controlled to measure a first distance from a preset position to the first film roll; the thickness of the first film roll is calculated based on the first distance and a preset distance between the laser distance measuring device and a fixing post of the first film roll; and the first state information is determined based on the thickness of the first film roll, thereby improving the accuracy of determining the first state information.

[0062] Furthermore, based on the first or second embodiment, a third embodiment of the method for controlling automatic film splicing of aluminum profiles of the present invention is proposed. In this embodiment, after the step of controlling the spare film corresponding to the second film roll to be bonded to the in-use film corresponding to the first film roll, the method further includes:

[0063] The pulling-down component is controlled to drive the laminating portion of the first film roll to move.

[0064] In this embodiment, the pull-down member is used to move the protective film away from the film roll and toward the aluminum profile. During aluminum profile processing, the aluminum profile is typically placed horizontally for ease of transportation. Therefore, typically, the film roll is positioned above the aluminum profile, with the pull-down member moving the protective film downward. Furthermore, after the pull-down, a guide member is typically used to guide the protective film against the aluminum profile.

[0065] Further, refer to Figure 4 The step of controlling the pull-down component to drive the laminating portion of the first film roll to move includes:

[0066] Step S301, controlling the laminating component to maintain the laminating pressure between the spare film and the used film during the laminating process;

[0067] In this embodiment, a bonding cylinder is used to bond the spare film to the film in use. Generally speaking, it is only necessary to complete the pressing action of bonding to return to the initial position, which means that the bonding is completed. In this embodiment, after the bonding cylinder completes the pressing action, it does not return to the initial position, but maintains the corresponding action and corresponding pressure.

[0068] Step S302: Control the pull-down component to apply a first preset tension to the laminating portion of the first film roll and execute a preset pull-down control strategy, wherein the first preset tension is less than the minimum tension that causes deformation of the film in use and is greater than or equal to the minimum tension of the automatic aluminum profile laminating machine during the laminating process, and the preset pull-down control strategy includes: controlling the laminating pressure and controlling the first preset tension;

[0069] In this embodiment, while controlling the laminating component to maintain the laminating pressure between the spare film and the active film during the laminating process, the pull-down component is controlled to apply a first preset tension to the laminating portion of the first film roll and execute a preset pull-down control strategy. The preset pull-down control strategy here primarily controls the laminating pressure and changes the first preset tension.

[0070] Step S303: When the preset pull-down index is reached, the preset pull-down control strategy is stopped.

[0071] The preset indicator here may be a target displacement distance for pulling down, and the preset pull-down control strategy is stopped after the target displacement distance for pulling down is reached.

[0072] In this embodiment, the bonding pressure between the spare film and the in-use film during the bonding process is maintained by controlling the bonding component; and the pull-down component is controlled to apply a first preset tension to the bonding portion of the first film roll, and a preset pull-down control strategy is executed, thereby effectively avoiding the problem of breakage and separation in the pull-down process due to poor bonding effect of the bonding portion. When the preset pull-down index is reached, the preset pull-down control strategy is stopped, thereby effectively avoiding problems in the automatic film splicing process, reducing the failure rate, and improving the production efficiency of the automatic film laminating machine for aluminum profiles as a whole.

[0073] Furthermore, based on the third embodiment, a fourth embodiment of the automatic film splicing control method for aluminum profiles of the present invention is proposed, wherein the step of executing the preset pull-down control strategy includes:

[0074] Adjusting the laminating pressure corresponding to each moment and detecting the position information of the laminating portion at each moment, wherein the laminating pressure decreases over time;

[0075] When the position information of the laminating portion at two adjacent moments changes, the adjustment of the laminating pressure is stopped, and the first preset tension corresponding to each moment is adjusted.

[0076] It should be noted that during the automatic film splicing process of aluminum profiles, the spare film and the active film on the bonding section may not completely overlap due to vibration and other factors. Furthermore, the area of the bonding cylinder is fixed during the bonding process, resulting in a small actual bonding area and the possibility of tearing during the pull-down process. In this embodiment, the bonding pressure decreases over time, and when the position information of the bonding section changes between two adjacent moments, the corresponding bonding area of the bonding section increases due to the pull-down process, thereby improving the overall stability of the bonding section.

[0077] In this embodiment, the first preset pulling force can be adjusted within a suitable range, thereby increasing the pulling speed and further improving the overall efficiency of the automatic film laminating machine.

[0078] Furthermore, before the step of executing the preset pull-down control strategy, the method further includes:

[0079] Count the failure rates corresponding to each different control strategy to obtain multiple failure rates;

[0080] The preset pull-down control strategy is determined among different control strategies according to the failure rate.

[0081] In this embodiment, the failure rate is calculated by dividing the number of failures for each control strategy by the number of automatic film splicing operations. Of course, other indicators can also be used as technical indicators for evaluating control strategies. In other embodiments, an overall efficiency indicator can be selected, which calculates the film length applied per unit time for each control strategy, thus also taking into account the time required for the film splicing process.

[0082] Furthermore, when the second status information indicates that the second film roll does not exist, a prompt message is issued, wherein the prompt message is to replenish a new film roll.

[0083] In this embodiment, even if the second status information indicates that the second film roll does not exist, the automatic profile laminating machine is actually still running. In some embodiments, the second status information indicating that the second film roll does not exist often appears after film splicing is completed.

[0084] In addition, an embodiment of the present invention further provides an automatic film splicing control device for aluminum profiles, the automatic film splicing control device for aluminum profiles comprising:

[0085] an acquisition module, configured to acquire first status information of a first film roll and second status information of a second film roll, wherein the first film roll is a film roll currently in use and the second film roll is a spare film roll currently;

[0086] an identification module configured to, when the first status information indicates that the film roll is insufficient and the second status information indicates that a second film roll exists, stop laminating the film and control the spare film corresponding to the second film roll to be laminated with the used film corresponding to the first film roll;

[0087] The control module is used to cut off the connection between the first film roll and the in-use film when the standby film and the in-use film are completely attached, and to perform the film attaching task.

[0088] In addition, an embodiment of the present invention further proposes an automatic film laminating machine for aluminum profiles, the automatic film laminating machine for aluminum profiles comprising: a memory, a processor, and an automatic film laminating control program for aluminum profiles stored in the memory and operable on the processor, the automatic film laminating control program for aluminum profiles being configured to implement the steps of any one of the above-mentioned automatic film laminating control methods, with reference to Figure 5 , Figure 5 This is an example diagram of an automatic film laminating machine for aluminum profiles. The automatic film laminating machine for profiles may include: two film rolls, a downward cylinder, a cutter cylinder, a laminating cylinder, and a guide cylinder. One of the film rolls corresponds to the film in use, and the other film roll corresponds to the spare film.

[0089] In addition, an embodiment of the present invention further provides a storage medium storing an automatic film splicing control program for aluminum profiles. When the automatic film splicing control program for aluminum profiles is executed by a processor, the steps of any of the above-mentioned automatic film splicing control methods for aluminum profiles are implemented.
