[0003] Cutting rule sample method: A standard shape sample is manually cut and then weighed, and the mass per unit area is manually calculated;
[0004] Manual conversion method after weighing: After weighing, manually calculate the mass per unit area based on the area;
[0005] Template sampling method: Area estimation is performed using templates, which is inefficient and prone to errors.
[0006] These methods suffer from problems such as area measurement relying on regular shapes, cumbersome manual operation, large errors, and inability to be automated. Utility Model Content

Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0037] Please see Figures 1 to 3 This utility model discloses a fabric unit area mass measuring device 1, including a base 10, a weighing module 20, a light source module 30, a measuring platform 40, a support 50, an image acquisition module 60, and a control module (not shown). The weighing module 20 is disposed above the base 10 and is used to measure the mass of the fabric to be measured. The light source module 30 is disposed above the weighing module 20. The measuring platform 40 is disposed above the light source module 30 and is used to place the fabric to be measured; the measuring platform 40 is made of transparent material to allow light from the light source module 30 to pass through. The support 50 is fixedly disposed on the base 10. The image acquisition module 60 is fixedly disposed on the support 50 and is used to acquire a shadow image of the fabric to be measured. The control module is communicatively connected to the weighing module 20 and the image acquisition module 60, and is used to calculate the area of the shadow image based on an image algorithm, and to calculate the unit area mass of the fabric to be measured based on the area and mass.
[0038] Specifically, the image acquisition module 60 is a camera device with an autofocus lens.
[0039] It is important to understand that during area measurement, the fabric to be measured is placed on the measuring platform 40. The light source module 30 below the measuring platform 40 emits light. Some light, partially blocked by the fabric, cannot reach the camera device, while the unblocked light does. After the camera device acquires the image signal, the control module binarizes the image, converting it into a clear black-and-white binary image. The fabric portion is black, and the background portion is white, creating a difference image between the fabric and the background. Then, the overall area of the fabric is obtained through irregular area integration. Compared to existing fabric area measurement methods, this invention, through the cooperation of the image acquisition module 60, the light source module 30, and the measuring platform 40, not only improves measurement efficiency but also helps reduce measurement errors. Furthermore, this invention can support the measurement of the unit area mass of fabrics with irregular edges and holes, and can be applied to sample testing, R&D, and quality inspection stages in the fabric manufacturing process.
[0040] Specifically, the area measurement accuracy error of this utility model is less than or equal to 0.1 cm².
[0041] In some embodiments, the weighing module 20 includes a balance transmission shaft 21, a support base 22, and stress columns 23. The input end of the balance transmission shaft 21 is connected to the measuring platform 40 and is used to transmit the gravity signal of the fabric to be tested. The support base 22 is connected to the output end of the balance transmission shaft 21 and is used to receive the gravity signal. Several stress columns 23 are disposed above the support base 22. The stress columns 23 are communicatively connected to the control module and are used to convert the gravity signal into an electrical signal and transmit it to the control module. Through the cooperation of the balance transmission shaft 21, the support base 22, and the stress columns 23, the mass of the fabric to be tested can be obtained without separate weighing.
[0042] Specifically, the weighing module 20 is mounted on a mounting bracket 24. The mounting bracket includes a first side plate 26 and a second side plate 27 connected to both sides of a connecting plate 25 in the middle. The first side plate 26 is used to contact and install with the base 10. The weighing module 20 is mounted on the side of the second side plate 27 facing the first side plate 26. The light source module 30 is located on the side of the second side plate 27 away from the first side plate 26.
[0043] Specifically, there are four stress columns 23. Of course, this invention does not limit the number or specific arrangement of the stress columns 23.
[0044] Specifically, the weighing error of the weighing module 20 is less than or equal to 0.001g.
[0045] In some embodiments, the fabric unit area mass measuring device 1 further includes an operation interface module, which is communicatively connected to the control module. The operation interface module includes a display screen 70, which is used to display and export the unit area mass data of the fabric to be measured.
[0046] Understandably, the fabric unit area mass measuring device 1 can be connected to a computer. By exporting the unit area mass measurement data to the computer, a measurement report can be generated, facilitating the query and traceability of the measurement data.
[0047] Specifically, the light source module 30 is an LED array. Of course, this invention does not limit the configuration of the light source module 30.
[0048] In some embodiments, an adjustable foot 80 is also provided below the base 10. By providing the adjustable foot 80, the height, orientation, and other properties of the fabric unit area mass measuring device 1 can be adjusted. In a specific example, an adjustable foot 80 with casters can also be selected to facilitate the movement of the measuring device.
[0049] Specifically, there are four adjustable feet 80.
[0050] Specifically, the base 10 is also equipped with a start button 90, which is used to start or stop the measurement process of fabric unit area mass.
[0051] Specifically, the measuring platform 40 is an acrylic sheet. Of course, the measuring platform 40 can also be made of other transparent materials, and this utility model does not impose any restrictions on this.
[0052] To facilitate understanding of this utility model, the specific operation process of the measuring device in the embodiment of this utility model is briefly described below, which should not be regarded as a limitation of this utility model.
[0053] First, turn on the power of the fabric unit area mass measuring device 1, adjust the measuring device to a horizontal position, and set the weighing module 20 to zero through the display screen 70.
[0054] Next, place the sample on the measuring platform 40 and use an acrylic plate to gently press the fabric flat;
[0055] Next, after completing the relevant preparations, press the start button 90.
[0056] Next, the image acquisition module 60 automatically takes pictures to identify the outline and simultaneously weighs the fabric to obtain the mass. The control module automatically calculates the area of the fabric to be measured to calculate the mass per unit area and displays the measurement result of the mass per unit area on the display screen 70.
[0057] Finally, the measurement data during the measurement process is exported to the computer and a report is generated.
[0058] In this embodiment of the invention, the fabric unit area mass measuring device 1 includes a base 10, a weighing module 20, a light source module 30, a measuring platform 40, a support 50, an image acquisition module 60, and a control module. The weighing module 20 is positioned above the base 10 and can acquire the mass of the fabric to be measured. The light source module 30 is positioned above the weighing module 20, and a transparent measuring platform 40 is placed on the light source module 30. When the fabric to be measured is placed on the weighing platform, the portion blocked by the fabric contrasts with the surrounding portions that allow light to pass through, thus forming a shadow image of the fabric. The image acquisition module 60, positioned above the weighing platform, can acquire this shadow image. The control module acquires the mass and calculates the area of the shadow image, thereby calculating the unit area mass of the fabric. This invention can identify the area of irregular fabrics and simultaneously acquire the fabric mass. Based on the area and mass, it obtains the unit area mass of the fabric, automating the measurement of the unit area mass of the fabric. This simplifies the measurement process and improves measurement efficiency and accuracy.
[0059] The above-disclosed examples are merely preferred embodiments of the present utility model, intended to facilitate understanding and implementation by those skilled in the art. They should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model patent shall still fall within the scope of the present utility model.
