Description

Technical Field

[0001] This invention relates to the field of automatic cutting bed technology, and specifically to a method and system for adjusting a vacuum suction device for an automatic cutting bed. Background Technology

[0002] An automatic cutting machine mainly includes a cutting table, a beam, a cutting head, a vacuum suction device, and a control system. The beam is mounted on the cutting table and is driven by a drive shaft to move along the x-axis. The cutting head is mounted on the beam and is driven by a drive shaft to move along the y-axis. A cutting blade is mounted on the cutting head. The beam and cutting head together drive the cutting blade to complete various curves or straight lines on the table. The control system controls the cutting position, cutting pattern, path, cutting speed, cutting tool conversion, blade spacing, and the start, pause, and termination of cutting for the beam and cutting head. During cutting, the fabric needs to be laid flat on the cutting table. To prevent slippage between multiple layers of fabric, a plastic film is first placed over the layers. Then, a vacuum suction device places the fabric under negative pressure. The cutting head then drives the cutting blade to cut along the x-axis or y-axis, thus completing the cutting action.

[0003] However, during the cutting process, air leakage occurs along the cut path, which reduces the negative pressure and affects the cutting effect.

[0004] Therefore, how to ensure the cutting effect during the cutting process is a problem that needs to be solved. Summary of the Invention

[0005] The purpose of this invention is to provide a method and system for adjusting a vacuum suction device for an automatic cutting bed, which can adjust the negative pressure provided by the vacuum suction device during the cutting process, thereby improving the cutting effect.

[0006] To achieve the above objectives, the present invention provides a method for adjusting a vacuum suction device for an automatic cutting bed, comprising:

[0007] Step 1: Before cutting begins, obtain the first position coordinate information of the feature point; the first position coordinate information includes at least the first Z-axis coordinate of the feature point relative to the cutting table surface;

[0008] Step 2: During the cutting process, the second position coordinate information of the feature point is acquired in real time; the second position coordinate information includes at least the second Z-axis coordinate of the feature point relative to the cutting table surface;

[0009] Step 3: Determine the relationship between the first Z-axis coordinate and the second Z-axis coordinate. When the first Z-axis coordinate is less than the second Z-axis coordinate, adjust the suction force of the vacuum suction device so that the first Z-axis coordinate is not less than the second Z-axis coordinate.

[0010] In an optional embodiment, the first position coordinate information further includes the first X-axis coordinate and the first Y-axis coordinate of the feature point; the second position coordinate information further includes the second X-axis coordinate and the second Y-axis coordinate of the feature point.

[0011] The first X-coordinate and the first Y-axis coordinate are matched with the second X-axis coordinate and the second Y-axis coordinate to obtain the matching result;

[0012] If the matching result is a failure, the head trimming action is stopped.

[0013] In an alternative embodiment, the feature points are located within the cut pattern on the coating.

[0014] In an optional embodiment, the number of feature points is multiple; both the first Z-axis coordinate and the second Z-axis coordinate are the average of the coordinates of the multiple feature points.

[0015] In an optional embodiment, before step 1, the method further includes: obtaining the Z-axis coordinates of multiple feature points relative to the cutting table surface, and performing mean processing to obtain the mean Z-axis coordinates;

[0016] Based on the mean Z-axis coordinates, the adsorption force of the vacuum suction device is adjusted so that the difference between the Z-axis coordinates of each feature point and the mean Z-axis coordinates is within a threshold range.

[0017] In an optional embodiment, the method further includes: comparing the mean Z-axis coordinate with a reference value;

[0018] If the average Z-axis coordinate is greater than the reference value, then increase the suction force of the vacuum suction device so that the average Z-axis coordinate is not greater than the reference value.

[0019] In an optional scheme, the formula for obtaining the reference value is: Z = D1 × N + D2, where Z is the reference value; D1 is the thickness of the fabric; N is the number of layers of the fabric; and D2 is the thickness of the coating.

[0020] The present invention also provides an adjustment system for a vacuum suction device for an automatic cutting bed, comprising:

[0021] The first acquisition module is used to acquire the first position coordinate information of the feature point before the cutting begins; the first position coordinate information includes at least the first Z-axis coordinate of the feature point relative to the cutting table surface.

[0022] The second acquisition module is used to acquire the second position coordinate information of the feature point in real time during the cutting process; the second position coordinate information includes at least the second Z-axis coordinate of the feature point relative to the cutting table surface.

[0023] The judgment module is used to determine the size relationship between the first Z-axis coordinate and the second Z-axis coordinate;

[0024] An adjustment module is used to adjust the adsorption force of the vacuum suction device when the first Z-axis coordinate is less than the second Z-axis coordinate, so that the first Z-axis coordinate is not less than the second Z-axis coordinate.

[0025] In an optional embodiment, the adjustment system further includes a third acquisition module, which is used to acquire the Z-axis coordinates of multiple feature points relative to the cutting table surface before cutting begins, and perform averaging to obtain the Z-axis average coordinates.

[0026] The adjustment module is also used to adjust the adsorption force of the vacuum suction device based on the mean Z-axis coordinate, so that the difference between the Z-axis coordinate of each feature point and the mean Z-axis coordinate is within a threshold range.

[0027] In an optional embodiment, the judgment module is further configured to compare the mean Z-axis coordinate with a reference value;

[0028] The adjustment module is also used to increase the suction force of the vacuum suction device when the average Z-axis coordinate is greater than the reference value, so that the average Z-axis coordinate is not greater than the reference value.

[0029] The beneficial effects of this invention are as follows:

[0030] This invention collects the Z-axis coordinates of feature points in real time during the cutting process of the cutting head driving the cutting blade in the X-axis or Y-axis direction. When the Z-axis coordinate of the feature point increases, the suction force of the vacuum suction device is increased to reduce the air leakage phenomenon in the cutting trajectory after cutting, thereby reducing the impact of negative pressure changes on the cutting effect.

[0031] Furthermore, before cutting begins, the Z-axis coordinates of each feature point are averaged to obtain the average Z-axis coordinates; and based on the average Z-axis coordinates, the Z-axis coordinates of each feature point are adjusted. This achieves the goal of improving the flatness of the coating surface before cutting, thereby improving the cutting effect.

[0032] Furthermore, before cutting begins, the average Z-axis coordinate is compared with a reference value. This determines whether the average Z-axis coordinate is greater than the total thickness of the fabric being cut, thereby further improving the smoothness of the coated surface and enhancing the cutting effect.

[0039] Example 1

[0040] Reference Figure 1 This embodiment provides a method for adjusting a vacuum suction device for an automatic cutting bed, including:

[0041] Step 1: Before cutting begins, obtain the first position coordinate information of the feature point; the first position coordinate information includes at least the first Z-axis coordinate of the feature point relative to the cutting table surface;

[0042] Step 2: During the cutting process, the second position coordinate information of the feature point is acquired in real time; the second position coordinate information includes at least the second Z-axis coordinate of the feature point relative to the cutting table surface;

[0043] Step 3: Determine the relationship between the first Z-axis coordinate and the second Z-axis coordinate. When the first Z-axis coordinate is less than the second Z-axis coordinate, adjust the suction force of the vacuum suction device so that the first Z-axis coordinate is not less than the second Z-axis coordinate.

[0044] Specifically, in this embodiment, before step 1, the method further includes: acquiring the Z-axis coordinates of multiple feature points relative to the cutting table surface, and performing averaging to obtain the Z-axis average coordinates; based on the Z-axis average coordinates, adjusting the suction force of the vacuum suction device so that the difference between the Z-axis coordinates of each feature point and the Z-axis average coordinates is within a threshold range. This step, ensuring that the difference between the Z-axis coordinates of each feature point and the Z-axis average coordinates is within a threshold range before cutting, can improve the flatness of the coating surface before cutting, thereby improving the cutting effect.

[0045] In this embodiment, before step 1, the method further includes: comparing the average Z-axis coordinate with a reference value; if the average Z-axis coordinate is greater than the reference value, increasing the suction force of the vacuum suction device so that the average Z-axis coordinate is not greater than the reference value.

[0046] The formula for obtaining the baseline value is: Z = D1 × N + D2, where Z is the baseline value; D1 is the thickness of the fabric; N is the number of layers of fabric; and D2 is the thickness of the coating.

[0047] Before cutting begins, the average Z-axis coordinate is compared with the reference value to determine whether the average Z-axis coordinate is greater than the total thickness of the fabric being cut, thereby further improving the flatness of the coated surface and enhancing the cutting effect.

[0048] The feature points in the above two steps can be the same as the feature points in step 1, or they can be other different feature points.

[0049] After the above two steps are completed, steps 1, 2, and 3 are executed sequentially. In step 1, the number of feature points can be one or more; when the number of feature points is multiple, the first Z-axis coordinate and the second Z-axis coordinate are both the average of the coordinates of the multiple feature points. In this embodiment, all feature points are located within the cut pattern on the film (corresponding to the position of the cut piece).

[0050] In this embodiment, the first position coordinate information further includes the first X-axis coordinate and the first Y-axis coordinate of the feature point; the second position coordinate information further includes the second X-axis coordinate and the second Y-axis coordinate of the feature point; the first X-axis coordinate and the first Y-axis coordinate are matched with the second X-axis coordinate and the second Y-axis coordinate to obtain a matching result; if the matching result is a matching failure, the cutting head action is stopped. This step is to determine whether the fabric has shifted; if the fabric has shifted, the coordinate values ​​before and after are different, and the matching fails.

[0051] In this embodiment, during the cutting process, the relationship between the first Z-axis coordinate and the second Z-axis coordinate is judged in real time. If the first Z-axis coordinate is smaller than the second Z-axis coordinate, it indicates that air leakage has occurred, causing the top surface of the fabric to rise. At this time, it is necessary to increase the suction force of the vacuum suction device to reduce the air leakage phenomenon in the cutting trajectory, thereby reducing the impact of negative pressure changes on the cutting effect.

[0052] Example 2

[0053] This embodiment provides an adjustment system for a vacuum suction device used in an automatic cutting bed, including:

[0054] The first acquisition module is used to acquire the first position coordinate information of the feature point before the cutting begins; the first position coordinate information includes at least the first Z-axis coordinate of the feature point relative to the cutting table surface.

[0055] The second acquisition module is used to acquire the second position coordinate information of the feature point in real time during the cutting process; the second position coordinate information includes at least the second Z-axis coordinate of the feature point relative to the cutting table surface.

[0056] The judgment module is used to determine the size relationship between the first Z-axis coordinate and the second Z-axis coordinate;

[0057] An adjustment module is used to adjust the adsorption force of the vacuum suction device when the first Z-axis coordinate is less than the second Z-axis coordinate, so that the first Z-axis coordinate is not less than the second Z-axis coordinate.

[0058] During the cutting process of the cutting head driving the cutting blade to cut in the x-axis or y-axis direction, the device collects the Z-axis coordinates of the feature points in real time. When the Z-axis coordinate of the feature point increases, the suction force of the vacuum suction device is increased to reduce the air leakage phenomenon in the cutting trajectory after cutting, thereby reducing the impact of negative pressure changes on the cutting effect.

[0059] In this embodiment, the adjustment system further includes a third acquisition module, which is used to acquire the Z-axis coordinates of multiple feature points relative to the cutting table surface before cutting begins, and perform averaging processing to obtain the Z-axis average coordinates. The adjustment module is also used to adjust the suction force of the vacuum suction device based on the Z-axis average coordinates, so that the difference between the Z-axis coordinates of each feature point and the Z-axis average coordinates is within a threshold range. In this embodiment, before cutting begins, the Z-axis coordinates of each feature point are averaged to obtain the Z-axis average coordinates, and the Z-axis coordinates of each feature point are adjusted based on the Z-axis average coordinates. This achieves the purpose of improving the flatness of the coating surface before cutting, thereby improving the cutting effect.

[0060] In this embodiment, the judgment module is further configured to compare the average Z-axis coordinate with a reference value; the adjustment module is further configured to increase the suction force of the vacuum suction device when the average Z-axis coordinate is greater than the reference value, so that the average Z-axis coordinate is not greater than the reference value. In this embodiment, before cutting begins, the average Z-axis coordinate is compared with a reference value to determine whether the value of the average Z-axis coordinate is greater than the total thickness of the fabric being cut, thereby further improving the flatness of the coated surface and enhancing the cutting effect.
