Technical Field
[0001] This utility model relates to the field of pultrusion product manufacturing technology, and specifically to a pultrusion product quality testing device. Background Technology
[0002] Pultruded products are composite material products manufactured through the pultrusion process. Due to the characteristics of the pultrusion process, pultruded products are generally in the form of strips or columns. For strip and column products, the main quality indicators include length and straightness.
[0003] Current technology for quality inspection of pultruded products mainly relies on manual methods. This involves checking the straightness of the product using a marble platform and manually measuring the length of the product using a steel ruler. However, manual quality inspection is prone to errors, is costly, and yields inconsistent results. Summary of the Invention

[0030] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0031] The following is a reference to the appendix. Figures 1 to 2 This invention provides a detailed description of the pultrusion product quality testing device 100 according to an embodiment of the present invention.
[0032] like Figure 1 and Figure 2 As shown, the pultrusion product quality inspection device 100 of this utility model embodiment includes a base 1, a guide rail 2, a grating ruler 3, a clamp 4, and a baffle 5.
[0033] The guide rail 2 and the grating ruler 3 are mounted on the base 1. A dial indicator is mounted on the caliper 4. The caliper 4 is connected to the guide rail 2 and moves along the guide rail 2. The base 1 can be made of metal; cast aluminum can be selected from the perspectives of cost and durability.
[0034] The base 1 is provided with a measuring area 10 parallel to the guide rail 2, and the pultruded product 6 to be tested is placed in the measuring area 10.
[0035] The grating ruler 3 is parallel to the measuring area 10 and is used to determine the flatness of the pultruded product 6 to be tested. The dial indicator mounted on the caliper 4, together with the grating ruler 3, can detect the flatness of the pultruded product 6 to be tested. Multiple samples can be taken from the test surface of the pultruded product 6 using the dial indicator. The flatness is calculated based on the sampling results, and the flatness of the pultruded product 6 to be tested is determined based on the calculation results.
[0036] A baffle 5 is installed at one end of the pultruded product quality inspection device 100 to fix the pultruded product 6 to be tested. The baffle 5 can make the pultruded product 6 to be tested parallel to the grating ruler 3 and the guide rail, and at the same time keep one end of the pultruded product 6 to be tested at the length measurement origin, so as to perform length measurement of the pultruded product 6 to be tested.
[0037] The initial position of the caliper 4 is located at the opposite end of the guide rail 2 and the baffle 5. When measuring the pultruded product 6 to be tested, the caliper 4 moves from the initial position along the guide rail 2 towards the test position of the pultruded product 6. The caliper 4 is equipped with an elastic component 40 that contacts the pultruded product 6 to be tested. The length of the pultruded product 6 to be tested is determined based on the deformation of the elastic component.
[0038] Specifically, the caliper 4 moves along the guide rail 2. For ease of measurement, the initial position of the caliper 4 is located at the opposite end of the guide rail 2 and the baffle 5. Since the guide rail is parallel to the measurement area 10, and the baffle 5 keeps one end of the pultruded product 6 to be tested at the length measurement origin, the range of motion of the caliper 4 to measure the length of the pultruded product 6 is from the initial position to the position of the guide rail 2 corresponding to the length measurement origin of the pultruded product 6. Accordingly, when the caliper 4 moves from the initial position along the guide rail 2 towards the test position of the pultruded product 6, the length of the pultruded product 6 can be calculated from the distance the caliper 4 moves. Thus, after determining the qualified length of the pultruded product 6, the distance the caliper 4 needs to move along the guide rail 2 from the initial position towards the test position of the pultruded product 6 can be calculated.
[0039] When the caliper 4 moves along the guide rail 2 to the test position of the pultruded product (6) to be tested, since the caliper 4 is equipped with an elastic component 40 that contacts the pultruded product 6 to be tested, when the elastic component 40 contacts the pultruded product 6 to be tested, since the pultruded product 6 to be tested is a rigid body and will not deform, the elastic component 40 will deform. Thus, the length of the pultruded product 6 to be tested can be determined based on the deformation of the elastic component.
[0040] Therefore, the pultruded product quality inspection device 100 of this utility model can quickly and accurately inspect the flatness and length of pultruded products, effectively saving labor costs and improving the accuracy and efficiency of quality inspection.
[0041] Furthermore, the pultruded product quality inspection device 100 also includes a display screen 7, which displays the quality inspection data and results of the pultruded product 6 to be tested. The display screen 7 can directly provide feedback on the quality inspection results to the operator, facilitating the operator to continue subsequent processing.
[0042] Furthermore, the elastic component 40 is a spring. Using a spring as the elastic component is low-cost, simple in structure, and easy to apply.
[0043] Figure 2 It is a magnified view of a portion of the elastic component when multiple pultruded products are inspected simultaneously, such as... Figure 2As shown, the elastic component 40 consists of multiple independent springs arranged in an array. To improve efficiency by simultaneously measuring multiple pultruded products 6, the elastic component 40 consists of multiple independent springs arranged in an array. The specific distribution spacing of the springs can be set according to the size of the pultruded product 6. For ease of measurement, the springs can be arranged in a trapezoidal or rectangular shape in cross-section, and the corresponding pultruded products 6 can be stacked in a corresponding trapezoidal or rectangular shape. This allows for the simultaneous measurement of the length of multiple pultruded products 6. The flatness measurement of the pultruded products 6 can be performed one by one during the stacking process from bottom to top. This allows for both individual flatness measurement of the pultruded products 6 and a unified length measurement of the pultruded products 6 at the end, thus completing the quality inspection of the pultruded products 6 and effectively improving inspection efficiency.
[0044] Furthermore, the spring is connected to a pressure sensor, and the spring's deformation is obtained based on the pressure detected by the sensor. Since the spring deformation has a fixed correspondence with the pressure it experiences, the spring's deformation under a given pressure can be obtained. Therefore, the spring's deformation can be detected quickly and accurately using a pressure sensor.
[0045] Furthermore, a marker is nested within the spring. The marker marks the pultruded product 6 under test based on the quality inspection data and results. Specifically, the marker can be a retractable cylinder with a diameter smaller than the spring diameter. During measurement, the marker is in a retracted state, not affecting the length measurement of the pultruded product 6 under test. After measurement, based on the measurement results, the marker corresponding to the non-conforming pultruded product 6 can be extended to mark the corresponding non-conforming product 6. Specifically, this can be achieved by stamping the pultruded product 6 with a stamp on the surface of the marker that contacts the pultruded product 6, or by printing a mark on the surface of the marker that contacts the pultruded product 6. This makes the non-conforming pultruded product 6 visually prominently marked, facilitating operator identification and processing by automated equipment with image recognition capabilities.
[0046] Furthermore, the test position is equal to the difference between the fixed length and the allowable error of the pultruded product 6 under test. To effectively address the situation where the unqualified pultruded product 6 is shorter than its fixed length, the test position should be shorter than the fixed length of the pultruded product 6 under test; otherwise, the elastic component will not feel pressure when the pultruded product 6 is shorter than its fixed length. When the test position is equal to the difference between the fixed length and the allowable error of the pultruded product 6 under test, if the length of the pultruded product 6 is less than the fixed length by a value greater than the error, the elastic component will not feel pressure, and the pressure of 0 will be calculated as an unqualified value. When the length of the pultruded product 6 under test is within the error range of the fixed length, the pressure felt by the elastic component is a qualified value. When the length of the pultruded product 6 under test is greater than the fixed length by a value greater than the error, the pressure felt by the elastic component is an unqualified value.
[0047] The pultruded product quality inspection device 100 of this utility model can quickly and accurately inspect the flatness and length of pultruded products, and can also inspect multiple pultruded products at the same time. At the same time, it has a simple and reliable structure, which can effectively save labor costs and improve the accuracy and efficiency of quality inspection.
