[0026] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0027] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.

[0028] See also Figure 1 , Figure 1 : is a flow chart of a precise control method for applying film to the surface of aluminum profiles provided in an embodiment of the present application. In this embodiment, the execution subject of the precise control method is a terminal device. It is understandable that the types of terminal devices include but are not limited to mobile phones, tablet computers, laptop computers, ultra-mobile personal computers (Ultra-Mobile Personal Computer, UMPC), netbooks, personal digital assistants (Personal Digital Assistant, PDA), etc., and the embodiments of the present application do not impose any restrictions on the specific types of terminal devices.

[0029] See also Figure 1 The precise control method provided in the embodiment of the present application includes but is not limited to the following steps:

[0030] In S100 , in response to the first fixed point arrival signal, a cutter half-cut instruction is generated.

[0031] Without loss of generality, the precise control method can be applied to an aluminum profile film laminating production line. From the feed port to the discharge port, the aluminum profile film laminating production line may include a feed sensor, a first conveying device, a positioning trigger sensor, a film roll, a cutter, a second conveying device and a discharge sensor in sequence. The first conveying device may be a feed servo conveyor belt, and the second conveying device may be a discharge servo conveyor belt; the first conveying device is closer to the feed port than the second conveying device.

[0032] Specifically, the terminal device can first respond to the first fixed-point arrival signal to generate a cutter half-cut instruction, wherein the first fixed-point arrival signal is used to describe that the first target profile is located on the carrying surface of the second conveying device, and the signal generated after the end of the first target profile reaches the specified position, and the cutter half-cut instruction is used to instruct the preset cutter to half-cut the film roll; half-cutting refers to the cutter partially cutting the film roll instead of completely cutting it; the terminal device can determine whether the end of the first target profile reaches the specified position through a positioning trigger sensor.

[0033] In some possible implementations, since the distance between the feed sensor and the positioning trigger sensor is fixed, assuming that the positioning trigger sensor has a response fluctuation range of 5 milliseconds, when the aluminum profile passes through the positioning trigger sensor at a speed of two meters per second, a maximum error of ten millimeters will be generated, and when the aluminum profile passes through the same positioning trigger sensor at a speed of 0.3 meters per second, only an error of 1.5 millimeters will be generated. Therefore, in order to reduce the positioning error caused by the response error of the positioning trigger sensor, the terminal device can pre-set a maximum passing speed value to ensure that no matter how large the specific value of the film-laminating speed is, each aluminum profile can pass through the positioning trigger sensor at a low and uniform speed.

[0034] In S200 , in response to the second fixed-point arrival signal, a synchronous transportation instruction is generated.

[0035] Specifically, after the terminal device generates a half-cut instruction, the terminal device can generate a synchronous transport instruction in response to a second fixed-point arrival signal, wherein the second fixed-point arrival signal is used to describe that the second target profile is located on the carrying surface of the first conveying device, and the signal generated after the head end of the second target profile reaches the specified position; the synchronous transport instruction is used to instruct the first conveying device and the second conveying device to operate at a preset first transport speed.

[0036] In S300 , in response to the first position arrival signal, an accelerated transport instruction is generated to disconnect the film roll at the position where the film roll is to be half-cut.

[0037] Specifically, after the terminal device generates a synchronous transport instruction, the terminal device can generate an accelerated transport instruction in response to the first position arrival signal, so that the film roll is disconnected at the half-cut position due to the speed difference, so that under the premise that the two aluminum profiles are tightly connected at the head and tail, the speed difference is used to pull the half-cut film apart, so that there is no need to reserve a four to five centimeter cutting area, thereby achieving waste-free use of the film and avoiding excess waste of protective film. The first position arrival signal is used to describe the signal generated after the end of the first target profile arrives at the preset area in the second conveying device; the accelerated transport instruction is used to instruct the second conveying device to operate at a second transport speed, which is greater than the first transport speed.

[0038] In some possible implementations, in order to effectively improve the entire film processing process, please refer to Figure 2 Before step S100, the method further includes but is not limited to the following steps:

[0039] In S101 , in response to a first feed start signal, a first start instruction is generated.

[0040] Specifically, at the beginning moment when there is no aluminum profile in the aluminum profile film laminating production line, the terminal device can generate a first start instruction in response to a first start feeding signal, wherein the first start feeding signal is used to describe the signal generated by the feed sensor triggered by the head end of the first target profile; the feed sensor is located at the feed port; the first start instruction is used to instruct the first conveying device and the second conveying device to operate at a first transport speed.

[0041] In S102 , in response to the first exit feed signal, a deceleration transport instruction is generated.

[0042] Specifically, after the terminal device generates the first start instruction, the terminal device can generate a deceleration transport instruction in response to the first leaving feed signal, wherein the first leaving feed signal is used to describe the signal generated by the head end of the first target profile leaving the feed sensor. Exemplarily, the head end of the first target profile can be any corner point on one end where the first target profile first enters the aluminum profile film production line; the deceleration transport instruction is used to instruct the first conveying device and the second conveying device to operate at a third conveying speed; the third conveying speed is less than the first conveying speed.

[0043] In some possible implementations, since the distance between the feed sensor and the positioning trigger sensor is fixed, and the aluminum profile needs deceleration time to reduce from a high speed to a low uniform speed, and the film laminating requirements are different, the feed speed is also different. In order to achieve the entire deceleration process in the shortest time, the deceleration position of the aluminum profile can automatically change according to the set film laminating speed, that is, the terminal device can determine the deceleration position according to the current feed speed; exemplarily, when the distance between the feed sensor and the positioning trigger sensor is 1 meter and the speed of the aluminum profile is two meters per second, the aluminum profile can start to decelerate when it is 0.8 meters away from the positioning trigger sensor. When the distance between the feed sensor and the positioning trigger sensor is 1 meter and the speed of the aluminum profile is one meter per second, the aluminum profile can start to decelerate when it is 0.4 meters away from the positioning trigger sensor. The same is true for other speeds, so they are not repeated, thereby achieving that the aluminum profile has been reduced to the specified low uniform speed when it is fifty millimeters away from the positioning trigger sensor.

[0044] In some possible implementations, in order to further effectively improve the entire film laminating process, after step S102, the method further includes but is not limited to the following steps:

[0045] In S103 , in response to the second feed start signal, a second start instruction is generated.

[0046] Specifically, after the terminal device generates a deceleration transport instruction, the terminal device can generate a second start instruction in response to a second start feed signal, wherein the second start feed signal is used to describe the signal generated by the feed sensor triggered by the head end of the second target profile. Exemplarily, the head end of the second target profile can be any corner point on one end where the second target profile first enters the aluminum profile film production line; the second start instruction is used to instruct the first conveying device to operate at the first transport speed.

[0047] In some possible implementations, in order to improve the intelligence of the aluminum profile film production line, please refer to Figure 3 After step S103, the method further includes but is not limited to the following steps:

[0048] In S104, the real-time end position information of the first target profile is obtained, and the real-time head end position information of the second target profile is obtained.

[0049] Specifically, the terminal device can obtain the real-time end position information of the first target profile, and simultaneously obtain the real-time head end position information of the second target profile, wherein the real-time end position information is used to describe the real-time position corresponding to the end of the first target profile. Exemplarily, the end of the first target profile can be any corner point on the end of the first target profile.

[0050] In S105, remaining distance information is generated based on the real-time end position information and the designated position, and interval distance information is generated based on the real-time head end position information and the designated position.

[0051] Specifically, after the terminal device obtains the real-time terminal location information and the real-time head-end location information, the terminal device can calculate the distance between the real-time terminal location information and the specified location to generate the remaining distance information, and at the same time calculate the distance between the real-time head-end location information and the specified location to generate the distance information.

[0052] In S106 , remaining time information is generated according to the remaining distance information and the third transport speed.

[0053] Specifically, after the terminal device generates the remaining distance information, the terminal device can generate the remaining time information according to the quotient of the remaining distance information divided by the third transport speed, wherein the remaining time information is used to describe the remaining time for the real-time terminal position information to reach the specified location.

[0054] In S107 , a first transport speed is determined according to the interval distance information and the remaining time information.

[0055] Specifically, after the terminal device generates the remaining time information, the terminal device can determine the first transportation speed according to the quotient of the distance information divided by the remaining time information, so that two aluminum profiles that enter the aluminum profile film production line one after another can be tightly connected head to tail.

[0056] In some possible implementations, in order to improve the film application effect while improving the efficiency of production resource utilization, please refer to Figure 4 Before step S102, the method further includes but is not limited to the following steps:

[0057] In S1021, preset film sticking speed information is obtained.

[0058] Specifically, the terminal device can obtain preset film pasting speed information, wherein the film pasting speed information is used to describe the film pasting speed required by the roll film for the aluminum profile of the signal.

[0059] In S1022, a third transport speed is determined according to the film sticking speed information.

[0060] Specifically, after the terminal device acquires the film pasting speed information, the terminal device may determine the third transport speed according to the film pasting speed information, wherein the third transport speed may be equal to the film pasting speed information.

[0061] The implementation principle of the precise control method for surface film pasting of aluminum profiles applied in the embodiment of the present application is as follows: the terminal device can first respond to the first fixed-point arrival signal to generate a cutter half-cut instruction, and then respond to the second fixed-point arrival signal to generate a synchronous transportation instruction, and finally respond to the first position arrival signal to generate an accelerated transportation instruction, so that the film roll is disconnected at the position where it is half-cut, thereby eliminating the need to reserve a cutter area, improving the efficiency of production resource utilization, and achieving zero waste of film pasting. It can also process two aluminum profiles at the same time, improving production efficiency, and highly dynamically planning the entire film pasting process to achieve optimal process self-adjustment for different film pasting speed requirements to achieve efficient and high-precision processing.
