The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (WIreless-FIdelity, WI-FI) interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM) memory, or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0041] In addition, the lifting device includes a motor, and optionally, a transmission device for transmitting the motor torque may be provided, such as a gear, a transmission rod, or a belt. The transmission device may be connected to the lifting component. The lifting component here is a component that directly contacts the aluminum profile, and the aluminum profile is lifted by directly contacting the aluminum profile.

[0042] In addition, various types of sensors may be included without limiting the type of sensor and the location of the sensor. Optionally, the sensor is a proximity sensor, an image acquisition device, a Hall sensor, etc.

[0043] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation of the lifting device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0044] 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 lifting control program.

[0045] exist Figure 1In the lifting device 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 lifting device of the present invention can be set in the lifting device, and the lifting device calls the aluminum profile lifting control program stored in the memory 1005 through the processor 1001, and executes the aluminum profile lifting control method provided by the embodiment of the present invention.

[0046] The embodiment of the present invention provides a method for controlling the lifting of an aluminum profile, referring to Figure 2 , Figure 2 The figure is a flow chart of a first embodiment of a method for controlling the lifting of an aluminum profile according to the present invention.

[0047] In this embodiment, the aluminum profile lifting control method includes:

[0048] Step S1, obtaining material parameters of the aluminum profile that reaches the initial position of the lifting device;

[0049] During the processing of aluminum profiles, the conveyor line conveys the aluminum profiles to the initial position of the lifting device, and the lifting device lifts the aluminum profile from the initial position to the terminal position. The material parameters of the aluminum profile here may include at least one of the aluminum profile size, aluminum profile cross section, and aluminum profile density. The aluminum profile size includes: width, height, length, etc. In addition, the aluminum profile size generally also includes thickness. The aluminum profile cross section here can be rectangular, square, circular, elliptical, T-shaped, I-shaped, etc., and different aluminum profile cross sections often have different position changes during the lifting process. The density of the aluminum profile is generally 2.7kg / dm^3. In this embodiment, the source of the material parameters may not be the same, and the data stored in the storage medium may be obtained, or the sensor may be set to obtain the material parameters of the aluminum profile at the initial position through the sensor. Generally speaking, the parameters of the density, aluminum profile cross section, etc. of the same batch of aluminum profiles are the same, which can be set and saved in the storage medium in advance. Therefore, the sensor only needs to obtain some of the material parameters.

[0050] Step S2, setting control parameters of a lifting motor according to the material parameters, wherein the lifting motor is used to control the lifting device to drive the aluminum profile to lift;

[0051] The torque, speed, acceleration, etc. of the lifting motor are set according to the material parameters, because different aluminum profiles will affect the operating load of the lifting motor, thereby affecting the actual operation of the motor. Specifically, a preset mapping table is set, and the control parameters of the lifting motor are set through the material parameters and the mapping table, so that the motor can operate according to the corresponding control parameters when lifting different aluminum profiles.

[0052] Step S3, controlling the lifting motor according to the control parameters, so that the lifting motor drives the lifting component of the lifting device to lift the aluminum profile to the end position.

[0053] In this embodiment, the lifting device may optionally include: a rotating mechanism, wherein the rotating mechanism rotates one circle to lift an aluminum profile. The rotating mechanism is driven by a motor, and the lifting motor is controlled by the control parameter, and the lifting motor drives the lifting device to lift the aluminum profile to the end position.

[0054] In this embodiment, the material parameters of the aluminum profile reaching the initial position of the lifting device are obtained; the control parameters of the lifting motor are set according to the material parameters, so that the parameters of the motor are set accordingly during each lifting process. Compared with the method of lifting with a cylinder, it can effectively avoid fluctuations in air pressure, and different motor control parameters can be adjusted based on different aluminum profile parameters, thereby reducing failures caused by different aluminum profile parameters and reducing the failure rate.

[0055] Further, based on the first embodiment, a second embodiment of the aluminum profile lifting control method of the present invention is proposed. In this embodiment, referring to Figure 3 , the step of controlling the operation of the lifting motor according to the control parameter also includes:

[0056] Step S41, detecting the position information and speed information of the aluminum profile in real time;

[0057] Specifically, a proximity sensor can be set at the initial position and the end position to obtain the position information, and a positioning sensor or a camera can also be set to determine the position information and speed information of the aluminum profile. In this embodiment, the method of obtaining the position information and speed information is not limited. The position information here includes height information and horizontal position information, and the speed information here is the speed in the vertical direction.

[0058] Step S42, determining a lifting operation state according to the position information and the speed information;

[0059] The real-time position information and speed information can determine the current lifting operation status of the aluminum profile.

[0060] Step S43, when the operating state is an abnormal state, updating the control parameters according to the position information and the speed information, and controlling the lifting motor according to the updated control parameters.

[0061] In this embodiment, when it is determined that the operating state is an abnormal state, the control parameters are updated so as to achieve real-time control of the motor, thereby avoiding a greater impact caused by the abnormality.

[0062] Further, based on the first embodiment or the second embodiment, a third embodiment of the aluminum profile lifting control method of the present invention is proposed. In this embodiment, referring to Figure 4 , the step of determining the lifting operation state according to the position information and the speed information comprises:

[0063] Step S421, when the position information matches the preset position information, and the speed information matches the preset speed information, determining that the lifting operation state is a normal state;

[0064] It should be noted that the preset mapping table actually contains preset position information corresponding to each time in the lifting process. By setting the control parameters of the lifting motor through the material parameters and the mapping table, the theoretical position information and theoretical speed information of the aluminum profile during lifting have actually been determined. Generally, the preset position information is the theoretical position information of the aluminum profile during lifting, and the preset speed information is the theoretical speed information of the aluminum profile during lifting. When the position information is equal to the preset position information, and the speed information is equal to the preset speed information, it is determined that the lifting operation state is normal;

[0065] Step S422: When the position information does not match the preset position information, or when the speed information is equal to the preset speed information and does not match, it is determined that the lifting operation state is an abnormal state.

[0066] In this embodiment, the lifting operation state is determined according to the position information and the speed information, thereby improving the accuracy of the lifting operation state judgment.

[0067] Further, based on any of the above embodiments, a fourth embodiment of the aluminum profile lifting control method of the present invention is proposed. In this embodiment, the step of updating the control parameter according to the position information and the speed information includes:

[0068] Calculating a position deviation value according to the position information and preset position information, and calculating a speed deviation value according to the speed information and the preset speed information;

[0069] Specifically, the difference between the height of the position information and the preset height of the preset position information is calculated as the position deviation value, and the difference between the speed information and the preset speed information is calculated as the speed deviation value.

[0070] Determine first deviation correction data according to the position deviation value and the speed deviation value;

[0071] The first deviation correction data is determined according to the position deviation value and the speed deviation value conversion coefficient, wherein the conversion coefficient is based on the conversion relationship between the operation angle of the lifting motor and the operation position of the lifting component.

[0072] The control parameter is updated according to the first correction data.

[0073] Specifically, the control parameter is updated according to the first correction data and the current control parameter.

[0074] In this embodiment, the position deviation value is calculated by using the position information and the preset position information, and the speed deviation value is calculated based on the speed information and the preset speed information, and the first correction data is determined based on the position deviation value and the speed deviation value, and the control parameters are updated based on the first correction data, thereby improving the real-time and accuracy of the update of the control parameters.

[0075] Further, based on any of the above embodiments, a fifth embodiment of the aluminum profile lifting control method of the present invention is proposed. In this embodiment, the step of determining the first correction data according to the position deviation value and the speed deviation value includes:

[0076] Determine a plurality of target speed curves according to the position deviation value and the speed deviation value;

[0077] According to the maximum acceleration and adjustment time of the lifting motor, one of the multiple target speed curves is selected as the first correction data.

[0078] In this embodiment, it should be noted that the target speed curve can also be replaced by a target position curve, which is actually the execution result corresponding to the control parameters of a corresponding motor. The maximum acceleration of the lifting motor here is actually the operating capacity of the lifting motor. Based on the operating capacity of the lifting motor, unreasonable target speed curves can be effectively avoided. The adjustment time here can be immediate adjustment or adjustment after waiting for a preset time. Different adjustment times reflect the sensitivity during the lifting process.

[0079] Furthermore, after the step of controlling the lifting motor according to the control parameter, the method further includes:

[0080] When it is detected that the aluminum profile has moved to the terminal position, arrival information is sent to enable the corresponding transport line to drive the aluminum profile to move.

[0081] In this embodiment, when it is detected that the aluminum profile reaches the terminal position, the aluminum profile is driven to move by the transport line corresponding to the terminal position, and after the aluminum profile completely leaves the lifting device, the motor controls the lifting component to move to the component initial position corresponding to the lifting component. The component initial position here can be below the initial position.

[0082] In addition, an embodiment of the present invention further provides an aluminum profile lifting control device, the aluminum profile lifting control device comprising:

[0083] An acquisition module, used for acquiring material parameters of the aluminum profile that reaches the initial position of the lifting device;

[0084] A calculation module, used for setting control parameters of a lifting motor according to the material parameters, wherein the lifting motor is used for controlling the lifting device to drive the aluminum profile to lift;

[0085] The control module is used to control the lifting motor according to the control parameters, so that the lifting motor drives the lifting device to lift the aluminum profile to the end position.

[0086] In addition, an embodiment of the present invention also proposes a lifting device, which includes: a memory, a processor, and an aluminum profile lifting control program stored in the memory and executable on the processor, wherein the aluminum profile lifting control program is configured to implement the steps of an embodiment of the aluminum profile lifting control method described in any one of the above items.

[0087] In addition, an embodiment of the present invention further proposes a storage medium, on which an aluminum profile lifting control program is stored. When the aluminum profile lifting control program is executed by a processor, the steps of any of the above-mentioned embodiments of the aluminum profile lifting control method are implemented.
