[0040] like Figure 1 As shown, the present invention provides an automatic shaping system for a window frame and door assembly, wherein the window frame and door assembly is composed of a window frame and a vehicle body, and includes:

[0041] The clamping assembly 1 includes a bracket and a plurality of tooling chucks 11 fixed on the bracket, and all the tooling chucks 11 are used to clamp and position the vehicle body;

[0042] The shaping assembly 4 includes a mechanical arm and a shaping chuck fixed on the mechanical arm, and the shaping chuck is driven by the mechanical arm to shape the part of the window frame to be shaped;

[0043] The detection component 5 includes a plurality of groups of measuring sensors, all of which are used to measure and obtain the size data of the window frame;

[0044] The control component 10 includes a controller, which is communicatively connected with the tooling chuck 11 , the robotic arm and the detection component 5 .

[0045] As described above, the automatic shaping system for window frame and door assembly of the present invention is:

[0046] In the course of work, Figure 1 As shown, firstly, the clamping component 1 is used to clamp and fix the window frame and door assembly 6 to position it; then the detection component 5 is used to measure the size data of the window frame and door assembly 6, and the size data is uploaded to the control component 10; then the control component 10 compares the obtained model data with the standard digital model data to determine whether the model data is out of tolerance. If there is a size out of tolerance, the corresponding shaping component 4 is further controlled to shape the out-of-tolerance part. If there is no out of tolerance, the control component 10 determines that it is a qualified product and packs it offline; after the shaping is completed, the control component 10 controls the detection component 5 to measure the window frame and door assembly 6 twice, and feeds back the secondary measurement model data to the control component 10; according to the secondary measurement model data, the control component 10 packs the window frame and door assembly 6 whose model data meets the preset requirements of the control component 10 offline, and controls the detection component 5 to measure for the third time for the window frame and door assembly 6 whose model data still exceeds the tolerance, and repeats the above steps until the number of measurements preset by the system is reached, and the window frame and door assembly 6 whose model data still exceeds the tolerance is isolated to the problem material box.

[0047] Further, such as Figure 2 As shown, an automatic shaping system for window frame and door assembly of this embodiment is also equipped with an alarm system 9, which is used to give an alarm when a system failure or abnormal operation of the automatic shaping system for window frame and door assembly is detected. In this embodiment, an audible and visual alarm is used for giving an alarm.

[0048] like Figure 2As shown, a window frame door assembly automatic shaping system of the present embodiment also includes a data storage module 8 and a data storage module 7, which are used to display and store the size data of the window frame door assembly 6, respectively. The display function facilitates the operator to confirm the system operation status in time, and the storage function is used to meet the requirements of subsequent information tracing. In this embodiment, after the detection component 5 obtains the size data, the data is further uploaded to the data storage module 7 for storage, which is convenient for subsequent data retrieval and use. In addition, the control component 10 processes the stored size data to obtain the model data and determine whether there is a size deviation, and sends a corresponding instruction to the shaping component 4 and synchronously provides the relevant model data to the data display component 8 for real-time display.

[0049] In this embodiment, the shaping chuck has a shaping surface with the same shape as the part of the window frame to be shaped, so that the window frame can be pushed in the opposite direction according to the program by the shaping chuck to achieve the shaping purpose, thereby realizing automatic shaping.

[0050] like Figure 1 As shown, in this embodiment, the clamping assembly 1 is provided with four tooling chucks 11, and each tooling chuck 11 includes a driving cylinder 2 and a clamping arm 3 connected to the driving cylinder 2. Figure 3 As shown, in the present embodiment, one tooling chuck 11 corresponds to two driving cylinders 2, so that the tooling chuck 11 can realize more complex clamping actions and meet more application scenarios; the above-mentioned four tooling chucks 11 are respectively used to fix the four corners of the vehicle body in the window frame door assembly 6 to ensure that the window frame door assembly 6 will not be offset during subsequent measurement and shaping; similarly, the number of tooling chucks 11 can also be adjusted according to the structure of the window frame door assembly 6 to ensure the fixation of the window frame door.

[0051] Further, such as Figure 1 As shown, in this embodiment, the detection component 5 includes a total of three measuring sensors, which are respectively used to obtain the size data of three corresponding positions of the window frame in the window frame door assembly 6. Similarly, the number of detection sensors can be increased or decreased to adapt to the detection requirements of the specific window frame door assembly 6. In addition, the detection component 5 in this embodiment also includes a positioning sensor for detecting the positioning state of the window frame door assembly 6 to ensure that the window frame door assembly 6 is clamped in place and the detection data is accurate and effective. Similarly, the number of measurement sensors can also be reasonably arranged according to the structural characteristics of different window frame door assemblies 6.

[0052] A method for automatically shaping a window frame and door assembly 6 in this embodiment includes the following steps:

[0053] 1) Clamp and position the window frame door assembly 6, measure the window frame in the window frame door assembly 6 by using a measuring sensor, obtain dimension data, and transmit the dimension data to the control component 10;

[0054] 2), the control component 10 obtains the model data of the window frame and door assembly 6 according to the size data, and determines whether the model data is within the preset data threshold. If so, the window frame and door assembly 6 out-of-tolerance position corresponding to the out-of-tolerance position of the model data is obtained, and the process proceeds to step 3); if not, the window frame and door assembly 6 is qualified;

[0055] 3) The control component 10 controls the shaping chuck to shape the out-of-tolerance part of the window frame and door assembly 6;

[0056] 4), after the shaping is completed, the controller controls the measuring sensor to measure the window frame and door assembly 6 again, and obtains the re-measured dimensional data; the controller obtains the model data of the window frame and door assembly 6 based on the re-measured dimensional data, and determines whether the model data is within the preset data threshold. If so, repeat steps 3) to 4), if not, the window frame and door assembly 6 is qualified.

[0057] In this embodiment, if the dimensional data obtained is still out of tolerance after the window frame and door assembly 6 is re-measured and reshaped three times in step 4), the window frame and door assembly 6 is unqualified and isolated; the number of repetitions of re-measurement in step 4) can be set according to actual production needs.

[0058] Further, such as Figure 1 As shown, in this embodiment, there are two shaping chucks, and the control component 10 automatically selects one according to the out-of-tolerance part of the window frame door assembly 6, thus avoiding the subsequent manual replacement of the shaping chuck and realizing automatic shaping. More shaping chucks can also be added according to the characteristics of the window frame door assembly.

[0059] In this embodiment, the design process of the shaping chuck is specifically as follows: the regional position of the defect in the window frame door assembly 6 is analyzed through the early model data of the window frame door assembly 6, the shaping part corresponding to the regional position of the defect is simulated through software, and then the shaping chuck with a shape corresponding to the shaping part is processed. The shaping chuck obtained in this way can more effectively shape the defective position of the window frame door assembly 6, and through this software simulation and re-verification method, the development cycle of the shaping chuck is greatly shortened, thereby improving efficiency.

[0060] In summary, the automatic shaping system and method of the window frame and door assembly of the present invention determines the out-of-tolerance part according to the size data provided by the measuring sensor through the control component 10, and further uses the corresponding shaping chuck to automatically shape the out-of-tolerance part, which solves the problem that the split window frame and door assembly 6 in the prior art adopts offline manual shaping and causes a lot of labor and cost waste. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0061] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
