[0037] The following further describes the specific embodiments of the present invention in detail by describing the optimal embodiments with reference to the drawings.

[0038] A test device for the adhesion force test of vehicle glass includes a placement structure 1-1 and an extrusion structure 2; the placement structure 1-1 includes at least two relatively arranged placement mechanisms 1; the placement mechanism 1 includes a placement seat 101 for placing the sample to be tested 4; the extrusion structure 2 includes an extrusion plate 21, and the extrusion plate 21 is connected with a driving mechanism 23; the driving mechanism 23 can drive the extrusion plate 21 to extrude the sample to be tested 4 placed on the placement structure 1-1; by the combined use of the placement structure 1-1 and the extrusion structure 2, the present invention realizes the test of the adhesion force of vehicle glass through a simple test device, and has the advantages of good versatility, simple operation, strong flexibility and high safety.

[0039] The test device disclosed by the present invention is mainly used for the adhesion force test of vehicle glass.

[0040] The placement structure 1-1 of the present invention is a structure for supporting and fixing the sample 4 to be tested.

[0041] The placement structure 1-1 mainly includes at least two relatively arranged placement mechanisms 1 for stably placing the sample 4 to be tested.

[0042] The placement seat 101 is the core component of each placement mechanism 1, which is used to carry the sample 4 to be tested subsequently and also facilitates the arrangement and placement of the sample 4 on the ground.

[0043] In actual use, the placement seat 101 is arranged on the ground, and the placement seat 101 provides a stable support platform to ensure that the sample 4 to be tested remains fixed during the test.

[0044] The extrusion structure 2 is a structure for applying pressure to the sample 4 to be tested placed on the placement structure 1-1.

[0045] The extrusion plate 21: The component that directly contacts the sample 4 to be tested and is used to apply pressure.

[0046] The driving mechanism 23: Connects the extrusion plate 21, provides power, and can drive the extrusion plate 21 to extrude the sample; the driving mechanism 23 can be a hydraulic cylinder.

[0047] The movement of the extrusion plate 21 is controlled by the driving mechanism 23 to apply pressure to the glass sample, simulating the external forces that the glass may be subjected to in actual use; it is used to test the bonding force of the glass and observe the bonding situation of the glass under the action of pressure until the glass falls off or breaks.

[0048] In the present invention, the sample 4 to be tested is placed on the placement structure 1-1; according to the shape and size of the sample, the placement mechanism 1 is adjusted to ensure the stable placement of the sample.

[0049] The clamping mechanism 3 is used to fix the sample on the placement seat 101 to prevent the sample from moving during the test.

[0050] Specific usage method: Start the driving mechanism 23 to drive the extrusion plate 21 to apply pressure to the sample; the extrusion plate 21 transmits the pressure to the sample by contacting the sample; gradually increase the pressure and observe the bonding situation of the glass; until the glass falls off or breaks, record the pressure value at this time as the test result of the glass bonding force.

[0051] Furthermore, in the present invention, the placement structure 1-1 includes a plurality of placement mechanisms 1, and the plurality of placement mechanisms 1 are arranged at intervals along the periphery of the sample 4 to be tested; in the present invention, through the plurality of placement mechanisms 1, the sample 4 to be tested can be supported more stably, especially for larger or irregularly shaped vehicle glass samples.

[0052] In the present invention, the multiple placement mechanisms 1 are not concentratedly arranged at one position, but are spaced along the periphery of the sample 4 to be measured.

[0053] By arranging them at intervals, the placement mechanism 1 can support the sample evenly from multiple directions, avoiding the sample from tilting or being unstable due to insufficient local support.

[0054] The above design can better adapt to samples of different shapes and sizes. Especially for glass samples with irregular shapes, the placement mechanism 1 arranged at intervals can better fit the contour of the sample.

[0055] The spaced arrangement of the multiple placement mechanisms 1 can provide a wider support area and enhance the stability of the entire test device.

[0056] Furthermore, in the present invention, a clamping mechanism 3 is provided on each placement seat 101. The clamping mechanism 3 includes two support clamping plates 31 that are spaced relatively and arranged on the placement seat 101; a placement inner cavity 34 is formed between the two support clamping plates 31; in the present invention, the clamping mechanism 3 mainly plays a role of support and limitation; at the same time, it can also squeeze and fix the sample 4 to be measured.

[0057] In the present invention, a clamping mechanism 3 is provided on each placement seat 101 for fixing the sample 4 to be measured.

[0058] The clamping mechanism 3 includes two support clamping plates 31 that are spaced relatively.

[0059] The support clamping plates 31 are spaced relatively: the two support clamping plates 31 are placed face to face with a space left in the middle; a space is formed between the two support clamping plates 31, which is called the placement inner cavity 34 for placing the sample 4 to be measured.

[0060] The placement inner cavity 34 is the core part of the clamping mechanism 3 for accommodating and fixing the sample 4 to be measured.

[0061] The height and width of the placement inner cavity 34 can be adjusted according to the size of the sample 4 to be measured to adapt to samples of different shapes and sizes.

[0062] Through the clamping action of the two support clamping plates 31, it is ensured that the sample 4 to be measured remains stable during the test and does not move or shake.

[0063] Furthermore, in the present invention, at least one of the two support clamping plates 31 on each placement seat 101 is movable; the height of the placement cavity 34 between the two support clamping plates 31 can be changed; at least one of the two support clamping plates 31 on each placement seat 101 is movable; this design allows for flexible adjustment of the position of the support clamping plates 31 according to the size and shape of the sample 4 to be measured: it can adapt to samples of different thicknesses and ensure that the sample can be stably clamped in the placement cavity 34.

[0064] In addition, the operator can quickly adjust the position of the support clamping plate 31 according to actual needs, improving the versatility and operational convenience of the test device.

[0065] The height of the placement cavity 34 between the two support clamping plates 31 can be changed.

[0066] This means that the horizontal position of the support clamping plate 31 can be adjusted to level the sample 4 to be measured.

[0067] Meanwhile, in the present invention, the support clamping plate 31 is connected to the placement seat 101 through an adjustment component; the adjustment component includes an adjustment slot 32 provided on the placement seat 101, and the support clamping plate 31 is connected to the placement seat 101 through an adjustment bolt 33; the adjustment bolt 33 is inserted into the adjustment slot 32; in the present invention, the support clamping plate 31 is connected to the placement seat 101 through the adjustment component.

[0068] Adjustment component: includes an adjustment slot 32 provided on the placement seat 101 and an adjustment bolt 33 for connecting the support clamping plate 31.

[0069] Adjustment bolt 33: inserted into the adjustment slot 32 for fixing the position of the support clamping plate 31.

[0070] The adjustment slot 32 provides a track for the support clamping plate 31 to move, allowing the support clamping plate 31 to move vertically within a certain range.

[0071] The adjustment slot 32 is usually elongated, and its length direction determines the movable direction of the support clamping plate 31.

[0072] The adjustment bolt 33 is used to fix the support clamping plate 31 on the placement seat 101; by tightening or loosening the adjustment bolt 33, the position of the support clamping plate 31 can be adjusted.

[0073] Loosen the adjustment bolt 33: enable the support clamping plate 31 to move freely within the adjustment slot 32.

[0074] Adjust the position of the support clamping plate 31: manually move the support clamping plate 31 according to the size and shape of the sample 4 to be measured, and adjust the width and height of the placement cavity 34.

[0075] After adjusting to the appropriate position, tighten the adjusting bolt 33 to firmly fix the support clamping plate 31 on the placing seat 101.

[0076] Specific operation steps:

[0077] Loosen the adjusting bolt 33:

[0078] Use a tool (such as a wrench) to loosen the adjusting bolt 33 so that the support clamping plate 31 can move freely within the adjusting groove 32.

[0079] Adjust the position of the support clamping plate 31:

[0080] According to the size of the sample 4 to be measured, manually move the support clamping plate 31 to adjust the width and height of the placing inner cavity 34 to ensure that the sample can be stably clamped.

[0081] Fix the support clamping plate 31:

[0082] After adjusting to the appropriate position, tighten the adjusting bolt 33 to firmly fix the support clamping plate 31 on the placing seat 101.

[0083] Check whether the support clamping plate 31 is firm to ensure that the sample will not move during the test.

[0084] By adjusting the position of the support clamping plate 31 in the present invention, it can adapt to vehicle glass samples of different thicknesses, enhancing the versatility of the test device.

[0085] The operator can quickly adjust the clamping mechanism 3 according to the specific requirements of the sample, making the test device more flexible.

[0086] By flexibly adjusting the position of the support clamping plate 31, it can ensure that the sample is evenly supported in the placing inner cavity 34, avoiding sample instability caused by insufficient local support.

[0087] Stable fixation can reduce errors caused by sample shaking or movement during the test, improving the accuracy of the test results.

[0088] Through uniform support and stable fixation, the risk of sample damage due to external forces during the test is reduced.

[0089] Furthermore, in the present invention, the support clamping plate 31 includes a transverse clamping plate 311 and a longitudinal clamping plate 312, and the transverse clamping plate 311 and the longitudinal clamping plate 312 are arranged perpendicular to each other; the transverse clamping plate 311 is connected to the placing seat 101 through the longitudinal clamping plate 312; the transverse clamping plate 311 is a clamping plate arranged in the horizontal direction, mainly used to contact the sample and provide horizontal support; the longitudinal clamping plate 312 is a plate member arranged in the vertical direction, mainly used to connect the transverse clamping plate 311 and the placing seat 101 and provide vertical support.

[0090] The horizontal clamping plate 311 and the vertical clamping plate 312 are perpendicular to each other, forming an "L" - shaped structure.

[0091] The horizontal clamping plate 311 is connected to the placing seat 101 through the vertical clamping plate 312, and the vertical clamping plate 312 plays a role in connection and support.

[0092] Generally, the horizontal clamping plate 311 and the vertical clamping plate 312 are designed as an integral structure, and the vertical clamping plate 312 is fastened to the placing seat 101 through the adjusting bolt 33.

[0093] Furthermore, in the present invention, the placing seat 101 includes a longitudinal plate 11 and a transverse plate 12; the longitudinal plate 11 and the transverse plate 12 are arranged perpendicular to each other; the longitudinal plate 11 and the transverse plate 12 are also connected by a diagonal brace 13; the longitudinal plate 11 is connected with a clamping mechanism 3; the longitudinal plate 11 is a plate arranged in the vertical direction, mainly used to provide vertical support; the transverse plate 12 is a plate arranged in the horizontal direction, mainly used to provide horizontal support; the diagonal brace 13 is used to connect the longitudinal plate 11 and the transverse plate 12 to enhance the structural stability of the placing seat 101.

[0094] The longitudinal plate 11 and the transverse plate 12 are perpendicular to each other, forming an "L" - shaped structure.

[0095] The diagonal brace 13 is connected between the longitudinal plate 11 and the transverse plate 12, playing a role in reinforcement to ensure that the placing seat 101 remains stable during the test.

[0096] Connection of the clamping mechanism 3: A clamping mechanism 3 is connected to the longitudinal plate 11 for fixing the sample to be tested 4.

[0097] The transverse plate 12 is fixed on the ground or the workbench, and specifically, the placing seat 101 can be installed and fixed by bolts.

[0098] Furthermore, in the present invention, a rubber pad 22 is provided on one side of the pressing plate 21 close to the sample to be tested 4; the rubber pad 22 is located on the side of the pressing plate 21 close to the sample to be tested 4, and its main function is to protect the glass sample from direct hard - contact damage.

[0099] The rubber pad 22 has a certain elasticity and can evenly distribute the force to the surface of the glass sample when applying pressure, avoiding glass breakage or damage caused by excessive local pressure.

[0100] Since the glass sample may have a certain curvature, the rubber pad 22 can better fit the surface of the sample to ensure the application of pressure distribution.

[0101] In the present invention, the rubber pad 22 can effectively reduce the risk of glass scratches, cracks or breakage caused by hard contact.

[0102] The rubber pad 22 can ensure that the force applied during the test is more evenly distributed, thus improving the accuracy and reliability of the test results.

[0103] The elasticity of the rubber pad 22 enables it to adapt to glass samples of different shapes and curvatures, enhancing the versatility of the test device.

[0104] In the present invention, the rubber pad 22 is usually made of rubber materials with high elasticity and high wear resistance, such as natural rubber, synthetic rubber or silicone rubber.

[0105] The thickness of the rubber pad 22 needs to be appropriate, providing sufficient elastic cushioning without affecting the test accuracy.

[0106] The rubber pad 22 can be fixed to the extrusion plate 21 by an adhesive or installed by mechanical fixing methods (such as snap fasteners, screws, etc.).

[0107] During long-term use, the rubber pad 22 may wear out. Therefore, it is required that the rubber pad 22 be connected to the extrusion plate 21 in a detachable manner.

[0108] A vehicle-mounted glass adhesion test method using the test device for vehicle-mounted glass adhesion test, the vehicle-mounted glass adhesion test method includes the following steps:

[0109] Step 1: Determine the size of the sample to be tested 4;

[0110] Step 2: Determine the ground to be tested and arrange the test device based on the size of the sample to be tested 4;

[0111] After Step 2 is completed, place the sample to be tested 4 on the placement structure 1-1 in the test device; then fasten the sample to be tested 4;

[0112] Step 4: Start the driving mechanism 23 to extrude the sample to be tested 4; until the glass falls off or breaks, record the force value at this time.

[0113] Based on the above test method, the present invention can realize the test and detection of the adhesion of vehicle-mounted glass.

[0114] The specific test steps are as follows:

[0115] Step 1: Determine the size of the sample to be tested 4

[0116] Measure the size of the sample to be tested 4 for subsequent arrangement of the test device.

[0117] Use measuring tools (such as a tape measure, caliper, etc.) to measure the length, width and thickness of the sample to be tested 4.

[0118] Record the size data of the sample to ensure that the test device can be adjusted according to these data in subsequent steps.

[0119] Step 2: Determine the ground to be tested and arrange the test device based on the size of the sample to be tested 4;

[0120] Purpose: Select a suitable test site and adjust the layout of the test device according to the sample size.

[0121] During operation: Select a flat and stable ground as the test site.

[0122] According to the size of the sample to be tested 4, adjust the placement mechanism 1 of the placement structure 1-1 to ensure that the placement mechanism 1 can adapt to the shape and size of the sample.

[0123] If there are multiple placement mechanisms 1 in the test device, arrange the placement mechanisms 1 at intervals along the perimeter of the sample according to the perimeter shape of the sample.

[0124] Step 3: Arrange the sample to be tested 4 on the placement structure 1-1 in the test device; then fasten the sample to be tested 4

[0125] Place the sample to be tested 4 on the placement structure 1-1 and fix the sample using the clamping mechanism 3.

[0126] Place the sample to be tested 4 on the placement seat 101 of the placement structure 1-1 to ensure that the sample is placed stably.

[0127] According to the size of the sample, adjust the position of the support clamping plate 31 so that the width and height of the placement inner cavity 34 match the sample.

[0128] Use the clamping mechanism 3 (such as bolts, nuts, etc.) to fix the sample on the placement seat 101 to ensure that the sample does not move during the test.

[0129] Check whether the sample is firmly fixed to ensure that it does not loosen during the test.

[0130] Step 4: Start the driving mechanism 23 to extrude the sample to be tested 4; until the glass falls off or breaks, record the force value at this time.

[0131] By applying pressure, test the bonding force of the glass and record the maximum force value.

[0132] Start the driving mechanism 23 to drive the extrusion plate 21 to apply pressure to the sample.

[0133] Gradually increase the pressure and observe the bonding condition of the glass.

[0134] Until the glass falls off or breaks, record the pressure value at this time.

[0135] This test method for the bonding force of vehicle glass ensures the accuracy and reliability of the test process through detailed steps and operation procedures.

[0136] Further, before the start of step 4 in the present invention, it is necessary to first perform preloading on the sample 4 to be tested; ensure that the extrusion structure 2 and the sample 4 to be tested are in full contact; the preloading can ensure full contact with the sample 4 to be tested.

[0137] The main purpose of preloading is to ensure full contact between the extrusion structure 2 and the sample 4 to be tested.

[0138] Avoid uneven local stress on the sample 4 to be tested.

[0139] Before the formal loading, through preloading, the air gap or other non-conforming situations between the extrusion plate 21 and the sample surface can be excluded, ensuring that the pressure can be better distributed on the sample surface.

[0140] Through preloading, it can be avoided that the sample is damaged at the initial stage of formal loading due to excessive local pressure.

[0141] Specific operations of preloading:

[0142] Initial loading: Start the driving mechanism 23 to apply a small initial load, such as 100 N, to the sample by the extrusion plate 21;

[0143] Holding time: Hold this load for a period of time, usually 5 seconds, to ensure full contact between the extrusion plate 21 and the sample surface;

[0144] Zero the load and release the pressure;

[0145] Repeat operation: Repeat the above loading and unloading process, usually 2 - 3 times, to ensure full contact between the extrusion structure 2 and the sample surface.

[0146] Importance of preloading:

[0147] Can improve the accuracy of test results

[0148] Through preloading, it can be ensured that during the formal loading process, the pressure can be more evenly distributed on the sample surface to a certain extent, avoiding deviation of test results caused by uneven local stress

[0149] Preloading can exclude errors caused by poor initial contact and improve the reliability of test results.

[0150] Preloading can avoid damage to the sample caused by excessive local pressure at the initial stage of formal loading and extend the service life of the sample.

[0151] By protecting the sample, reduce the test repetition caused by sample damage and lower the test cost

[0152] During preloading, the initial load required for preloading should be selected as a relatively small value, such as 100 N, to avoid exerting excessive pressure on the sample; the holding time should be long enough to ensure full contact between the extrusion plate 21 and the sample surface, usually 5 seconds; the preloading should be repeated 2 - 3 times to ensure full fitting; during the preloading process, the contact situation between the sample surface and the extrusion plate 21 should be carefully observed to ensure that there is no obvious gap or non - fitting phenomenon between the two.

[0153] Preloading is a very important step in the vehicle - mounted glass adhesion test. By ensuring full fitting between the extrusion structure 2 and the sample 4 to be tested, it can effectively improve the accuracy and reliability of the test results, and at the same time protect the sample from initial damage.

[0154] The present invention can effectively test the adhesion of glass and record the maximum force value through the methods of preloading and step - by - step loading.

[0155] In the preloading of the present invention, it is mainly to ensure full fitting between the extrusion structure 2 and the sample 4 to be tested, and avoid uneven local stress.

[0156] Before the formal loading, the sample 4 to be tested is pre - loaded first.

[0157] For example, first load to 100 N, hold for 5 seconds, then return the load to zero, and repeat twice to ensure full contact between the extrusion plate 21 and the sample surface.

[0158] After the preloading is completed, the formal loading is carried out;

[0159] It is required to load step - by - step during loading;

[0160] Gradually increase the pressure, observe the adhesion of the glass, and ensure the accuracy of the test results.

[0161] Specific operation

[0162] Start from 0 N, gradually and slowly apply the load;

[0163] Every time the load is increased by 200 N, hold for 5 seconds, and observe the adhesion of the glass.

[0164] Until the glass falls off or breaks, record the force value at this time.

[0165] By adjusting the placement structure 1 - 1 and the clamping mechanism 3, the test device of the present invention can adapt to vehicle - mounted glass samples of different shapes and sizes.

[0166] The operator can quickly adjust the test device according to the specific requirements of the sample, making the test device more flexible.

[0167] Through the spaced - apart placement mechanism 1 and the adjustable clamping mechanism 3, it is ensured that the sample is evenly supported during the test.

[0168] A stable fixation can reduce the errors caused by sample shaking or movement during the test and improve the accuracy of the test results.

[0169] Specifically:

[0170] The present invention discloses a test device for the adhesion test of vehicle glass, including a placement structure 1-1 and a pressing structure 2; the placement structure 1-1 at least includes two relatively arranged placement mechanisms 1; the placement mechanism 1 includes a placement seat 101 for placing a sample to be tested 4; the pressing structure 2 includes a pressing plate 21, and the pressing plate 21 is connected with a driving mechanism 23; the driving mechanism 23 can drive the pressing plate 21 to press the sample to be tested 4 placed on the placement structure 1-1.

[0171] Specifically, a test method for the adhesion of vehicle glass; includes the following steps:

[0172] Step 1: On a horizontal iron floor, use multiple placement mechanisms 1 to firmly clamp the sample to be tested 4 (the sample to be tested 4 is generally a car door bonded with glass or a cut side wall).

[0173] Step 2: Install the driving mechanism 23, which is generally a hydraulic (or mechanical) loading system and a load sensor, so as to apply a vertical load to the glass surface.

[0174] Step 3: Fit the rubber pad 22 on the pressing plate 21 with the sample to be tested 4, and perform preloading. First, load to 100N, hold for 5s, then zero the load, and repeat twice to ensure that the loading surface and the glass on the sample to be tested 4 are fully fitted.

[0175] Step 4: Start from 0N, gradually and slowly apply the load. Every time the load increases by 200N, hold for 5s, and check the bonding condition of the glass on the sample to be tested 4 until the glass on the sample to be tested 4 falls off or the glass breaks, and record the force value at this time.

[0176] In the present invention, the pressing plate 21 can be designed based on the glass contour of the sample to be tested 4; since the glass is generally not completely flat and has a certain curvature, the advantage of using a rubber soft panel is that it can be in large-area contact with the glass on the sample to be tested 4.

[0177] The placement structure 1-1 disclosed by the present invention can horizontally position and support the car door or the cut side wall, and firmly clamp it to ensure the firmness of the sample during the test.

[0178] The extrusion structure 2 mainly includes an extrusion plate 21 and a rubber pad 22 provided on the extrusion plate 21. The outlines of the extrusion plate 21 and the rubber pad 22 are designed based on the outline of the glass on the sample to be tested 4. Since glass is generally not completely flat and has a certain curvature, the advantage of using a rubber soft panel is that it can fit the glass over a large area, enabling the glass to be loaded more evenly.

[0179] The operation process is as follows:

[0180] First, use multiple placement mechanisms 1 to preliminarily position the sample, and then fix the placement mechanism 1 on the iron floor. In addition, in the present invention, the placement mechanism 1 can also be arranged first, and then the sample to be tested 4 can be arranged on the placement mechanism 1.

[0181] After the sample to be tested 4 is placed on each placement mechanism 1, adjust the clamping mechanism 3 on each placement mechanism 1.

[0182] First, adjust the support clamping plate 31 below each placement mechanism 1 to level the sample to be tested 4, and then firmly fix the support clamping plate 31 to the placement seat 101. After fixing the support clamping plates 31 below in multiple placement mechanisms 1, fasten the upper support clamping plate 31 on each placement seat 101 to its lower support clamping plate 31 to clamp the sample. Then fix the upper support clamping plate 31 on each placement seat 101 to the corresponding placement seat 101. Thus, the clamping of the sample to be tested 4 is completed.

[0183] Secondly, connect the extrusion plate 21 to the driving mechanism 23, then adjust the driving mechanism 23 to make the extrusion plate 21 as horizontal as possible with the glass surface in the sample to be tested 4, and then fix the extrusion structure 2.

[0184] Then conduct the test according to steps two and three in the above test method.

[0185] Based on the above design, the present invention realizes the test of the bonding force of vehicle glass through a simple test device, and has the advantages of good versatility, simple operation, strong flexibility, and high safety. The extrusion plate 21 used in the present invention in cooperation with the rubber pad 22 can effectively fit small-curvature glass, enabling the applied force to be more evenly distributed and protecting the glass from being damaged by hard contact.

[0186] Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
