[0002] The sealing problem is an important index affecting the quality of the automobile.

[0038] Example 1:

[0039] This invention provides a windshield sealing strip assembly, such as... Figures 1-3 As shown, it includes an air intake grille, a clip structure, and an adhesive layer 4. The lower end of the air intake grille 8 has a grille claw 9 protruding from it, and the front end of the grille claw 9 has a hook 91 protruding from it. The clip structure includes: a first metal frame 1 and a rigid component covering the outside of the first metal frame 1. The rigid component includes a strip 2 and a U-shaped groove 3 disposed at one end of the strip 2. The U-shaped groove 3 includes a curved arm 10 and a first straight arm 11 and a second straight arm 12 disposed on both sides of the curved arm 10. A snap-fit ​​6 is disposed between the end of the curved arm 10 near the strip 2 and the upper end of the second straight arm 12. The snap-fit ​​6 is used to seal and limit the grille claws 9 of the air intake grille 8. The end of the snap-fit ​​6 away from the strip 2 extends toward the first straight arm 11 to form a first barb 7 for cooperating with the hook 91. The end of the snap-fit ​​6 away from the strip 2 extends toward the second straight arm 12 to form a connecting part 601, and is integrally connected to the upper end of the inner wall of the second straight arm 12 through the connecting part 601. The U-shaped groove 3, the snap-fit ​​6, the first barb 7 and the connecting part 601 are made by an integral molding process, and the integral molding structure has stronger stability. The snap-fit ​​component 6 and the inner wall of the U-shaped groove 3 form a first hollow structure 602. The first hollow structure 602 ensures that the snap-fit ​​component 6 has a buffer space during compression. The grille claws 9 of the air intake grille 8 are snapped into the U-shaped groove 3 through the snap-fit ​​component 6. The adhesive layer 4 is applied to the upper surface of the strip component 2, and the strip component 2 is connected to the windshield 5 through the adhesive layer 4.

[0040] The rigid components are made of rigid PP material, which enhances the structural strength of the card strip. The snap-fit ​​part 6 and the connecting part 601 are made of soft TPE material, which can be flexibly deformed and has a wide range of applications. The one-piece molding process includes, but is not limited to, co-extrusion molding process, which makes the connection between the snap-fit ​​part 6 and the U-shaped groove 3 more stable and extends the service life of the card strip.

[0041] The first straight arm 11 of the U-shaped groove 3 is located at the end of the curved arm 10 away from the strip-shaped member 2, the second barb 13 is arranged at the inner wall of the end of the first straight arm 11 away from the curved arm 10, the second straight arm 12 is arranged at the connection between the curved arm 10 and the strip-shaped member 2, the slope part 14 is arranged at the end of the second straight arm 12 away from the curved arm 10, and the second metal framework 15 is arranged in the slope part 14. The included angle between the slope part 14 and the strip-shaped member 2 is an acute angle, preferably 55 degrees to 65 degrees, which can be symmetrical with the second barb 13 of the first straight arm 11, and the two cooperate to form a downward guiding inverted conical shape at the entrance of the U-shaped groove 3, facilitating the installation of the grid clamping jaw 9 of the air inlet grille 8, the slope part 14 includes a first abutting end 1401 and a second abutting end 1402, the connecting part 601 is fixed to the inner wall of the second abutting end 1402, the first abutting end 1401 is used for abutting against the front windshield 5, and the second metal framework 15 supports, so that the slope part 14 is stable and reliable.

[0042] The clamping piece 6 is in a curved shape and can realize stretching and bending, for example, a 3-shaped structure, an's'-shaped structure or other curved shapes. In the embodiment 1, the upper end of the clamping piece 6 is bifurcated to form a Y-shaped structure, and is made of a TPE soft material and has elasticity. Specifically, see Figure 3 The side, where the clamping piece 6 is connected with the first barb 7, is provided with a first connecting end 603, the first connecting end 603 is integrally formed with the first barb 7 and the connecting part 601 respectively, the side, where the connecting part 6 is connected with the inner wall of the U-shaped groove 3, is provided with a second connecting end 604, the second connecting end 604 is integrally formed with the inner wall of the U-shaped groove 3, a clamping piece main body 606 is formed between the first connecting end 603 and the second connecting end 604, a first hook groove 605 is formed between the first barb 7 and the side of the clamping piece main body 606 close to the first connecting end 603, and the first hook groove 605 forms a space for clamping the hook 91. The front end of the grid clamping jaw 9 of the air inlet grille 8 protrudes with the hook 91, the first hook groove 605 is used for hooking the hook 91, so as to realize the limiting effect on the grid clamping jaw 9; when the hook 91 is in the clamping state with the first hook groove 605, the clamping piece main body 606 is in a slightly compressed state and is in a curved wrinkle state, at this time, the first hollow structure 602 provides a space for extension and accommodation for the deformation of the clamping piece main body 606, so as to ensure the stability of the whole.

[0043] In order to realize the close cooperation between the clamping piece 6 and the grid clamping jaw 9, the clamping hook 91 of the grid clamping jaw 9 is bent towards the side of the clamping piece 6, forming a second hook groove 92 matched with the first barb 7. The shape of the first barb 7 is matched with the second hook groove 92. Optionally, a friction particle layer is arranged on the outer surface of the free end of the first barb 7 corresponding to the second hook groove 92. The friction particle layer can be made of damping material or other material capable of improving friction. One circle of the friction particle layer can ensure that the first barb 7 and the second hook groove 92 have considerable friction between them, avoiding slipping between them and improving the friction and cooperation. When the clamping hook 91 and the first hook groove 605 are in the clamping state, the first barb 7 is clamped into the second hook groove 92, forming a tight seal.

[0044] The working principle and beneficial effects of the above technical solution are as follows: The traditional air inlet grille 8 is connected with the clamping strip through the cooperation of the protruding blocking hook 93 on one side of the grid clamping jaw 9 and the second barb 13 of the first straight arm 11. However, during the production of the air inlet grille 8, the size or curvature of the grid clamping jaw 9 is prone to error. When the error is large and the size of the grid clamping jaw 9 is small, the grid clamping jaw 9 is prone to shaking in the U-shaped groove 3, and the pull-out force value of the grid clamping jaw 9 is small. After the air inlet grille 8 is installed, the grid clamping jaw 9 is prone to being pulled out of the U-shaped groove 3. Therefore, the clamping piece 6 is arranged in the U-shaped groove 3. The clamping piece 6 is in a curved shape. The first barb 7 is arranged on one side of the clamping piece 6. The clamping hook 91 is arranged at the corresponding position of the grid clamping jaw 9 and the clamping piece 6. The protruding blocking hook 93 is arranged on the other side of the grid clamping jaw 9, corresponding to the second barb 13. In this way, in the cooperation state, the clamping hook 91 and the first hook groove 605 are cooperated and sealed, and the first barb 7 and the second hook groove 92 are cooperated and sealed. The double hooking forms a stable 'locking' state, which can ensure that the grid clamping jaw 9 of the air inlet grille 8 is completely limited. In use, the adhesive layer 4 is prepared by coating adhesive on the surface of the strip-shaped piece 2. The adhesive is any one of pressure-sensitive adhesive or heat-sensitive adhesive. Then the adhesive is adhered to one side of the lower surface of the front windshield glass 5. Then the grid clamping jaw 9 of the air inlet grille 8 is inserted into the cavity of the U-shaped groove 3.

[0045] Referring to Figure 2In the process of inserting the grid clamping jaw 9 into the U-shaped groove 3, that is, when the grid clamping jaw 9 is inserted into the U-shaped groove 3 from the upper end opening of the U-shaped groove 3, the clamping hook 91 of the grid clamping jaw 9 abuts against the upper side of the first barb 7, the first barb 7 is pressed into a parallel state with the connecting portion 601, the grid clamping jaw 9 can drive the first barb 7 of the clamping piece 6 to bend downward through the clamping hook 91, the first barb 7 is compressed, the clamping hook 91 of the grid clamping jaw 9 will pass the lower side of the first barb 7 into the first hook groove 605, the clamping piece 6 has elasticity, the clamping piece 6 can make the other side of the grid clamping jaw 9 slide along the outer wall of the second barb 13 of the U-shaped groove 3, the clamping hook 91 of the grid clamping jaw 9 will slide through the lower side of the first barb 7 into the first hook groove 605 and abut against the first hook groove 605, when the clamping hook 91 slides into the first hook groove 605 below the first barb 7, under the elastic action, the first barb 7 is opened and restored to the original position, at this time, the first barb 7 abuts against and cooperates with the second hook groove 92, through the double abutment, the complete cooperation between the grid clamping jaw 9 and the clamping piece 6 is ensured, and loosening is avoided. At this time, the blocking hook 93 of the grid clamping jaw 9 cooperates with the lower wall of the second barb 13, so as to prevent the grid clamping jaw 9 from being pulled out of the clamping strip, improve the stability of the cooperation between the grid clamping jaw 9 and the clamping strip, in the process of insertion, the first barb 7 can drive the clamping piece 6 to move into the first hollow structure 602, ensure the smooth insertion of the grid clamping jaw 9, reduce the insertion force, and the installation is convenient. The setting of the first hollow structure 602 provides a space for the deformation of the clamping piece body 606, and ensures the stability of the clamping piece 6 in the use process;

[0046] Referring to Figure 3 and Figure 4 When the grid clamping jaw 9 needs to be pulled out of the U-shaped groove 3, the clamping hook 91 of the grid clamping jaw 9 hooks the first barb 7 to move upward, and the clamping piece body 606 is stretched; if the grid clamping jaw 9 is pulled out of the U-shaped groove 3, as shown in Figure 3 , the clamping hook 91 of the grid clamping jaw 9 drives the first barb 7 to move upward, the lower end of the clamping piece 6 is connected with the curved arm 10, the clamping piece body 606 is stretched, and the deformation amplitude of the first barb 7 can be reduced, so that the extrusion of the first barb 7 on the clamping hook 91 is improved, the pulling-out force of the grid clamping jaw 9 is increased, gradually, the clamping hook 91 is separated from the first hook groove 605, and the first barb 7 is separated from the first barb 7, at this time, the first barb 7 is also separated from the second hook groove 92, the grid clamping jaw 9 is separated from the U-shaped groove 3, and is pulled out of the U-shaped groove 3.

[0048] The working principle and beneficial effects of the above technical solution are as follows: the first protrusion 16 is arranged on the slope portion 14 and protrudes from the second straight arm 12 towards one end of the strip-shaped member 2, so that when the front windshield glass 5 is installed, the front windshield glass 5 can be in contact with the first protrusion 16 having elasticity, the first protrusion 16 can block the gap between the strip-shaped member and the front windshield glass 5, thereby improving the sealing performance of the front windshield glass 5, and achieving the effects of noise reduction and water sealing; the sealing strip 17 is arranged on the side of the first protrusion 16 close to the grid clamping jaw 9, and is used to abut on the inner side of the air inlet grid 8 to form a tight seal; the included angle between the sealing strip 17 and the slope portion 14 is an acute angle, preferably 45-60 degrees, which can ensure that when the grid clamping jaw 9 of the air inlet grid 8 is clamped into the U-shaped groove 3, the lower end surface of the air inlet grid 8 will press the sealing strip, thereby achieving the sealing between the lower end surface of the air inlet grid 8 and the U-shaped groove 3; when the upper end of the first protrusion 16 is horizontal and flush with the upper end surfaces of the front windshield glass 5 and the air inlet grid 8 in the installed state, the sealing strip 17 can be in contact with the air inlet grid 8 and bent downward, the sealing strip 17 is in close contact with the air inlet grid 8, which can reduce the gap between the strip-shaped member and the air inlet grid 8, and further improve the sealing performance of the strip-shaped member and the air inlet grid 8.

[0049] On the basis of the above scheme, as shown in Figure 1 The second protrusion 18 is arranged outside the curved arm 10 and is made of TPE soft material.

[0051] On the basis of the above scheme, the pull-out force of the grid clamping jaw 9 pulled out of the U-shaped groove 3 is limited, because the pull-out force of the grid clamping jaw 9 pulled out of the U-shaped groove 3 determines the stability and reliability of the product performance, the pull-out force of the grid clamping jaw 9 pulled out of the U-shaped groove 3 is not less than a preset pull-out force, the actual thickness of the first barb 7 is greater than the target thickness of the first barb 7, and the target thickness of the first barb 7 is calculated by the following formula:

[0052]

[0053] Wherein, H2 is the target thickness of the first barb 7, F1 is the preset pulling force, σ1 is the tensile strength of the first connecting end 603, S1 is the cross-sectional area of the first connecting end 603, σ2 is the tensile strength of the second connecting end 604, S2 is the cross-sectional area of the second connecting end 604, μ is the sliding friction coefficient of the side wall of the first barb 7 and the side wall of the hook 91, K is the elastic coefficient of the first barb 7 and the connecting part 601, δ is the preset minimum compression rate of the material of the first barb 7 and the connecting part 601, and H1 is the preset thickness of the connecting part 601.

[0054] The working principle and beneficial effects of the above technical solution are as follows: In order to prevent the grid clamping claw 9 from being pulled out of the U-shaped groove 3, the pulling force of the grid clamping claw 9 pulled out of the U-shaped groove 3 is not less than the preset pulling force, and the user can set the preset pulling force according to actual needs. Based on the preset pulling force, the actual thickness of the first barb 7 needs to be greater than the target thickness of the first barb 7 during the production process of the clamping piece 6, so as to ensure that the pulling force of the grid clamping claw 9 pulled out of the U-shaped groove 3 is not less than the preset pulling force. In order to improve the convenience of production of the clamping piece 6, the sizes of the first connecting end 603, the second connecting end 604 and the connecting part 601 of the clamping piece 6 remain unchanged, and only the target thickness of the first barb 7 needs to be adjusted according to the required preset pulling force during production, thereby improving the consistency and production efficiency of the clamping strip product. Specifically, the target thickness of the first barb 7 can be calculated according to the above formula. During the calculation process, the tensile strength of the first connecting end 603 and the second connecting end 604, and the elastic force of the compressed first barb 7 and the connecting part 601 on the side wall of the hook 91 during the pulling process are comprehensively considered, which can make the calculation of the target thickness of the first barb 7 more accurate. The preset minimum compression rate of the material of the first barb 7 and the connecting part 601 is 5%, which can ensure the elastic force of the compressed first barb 7 and the connecting part 601 on the side wall of the hook 91 during the pulling of the grid clamping claw 9, thereby preventing the grid clamping claw 9 from being easily pulled out of the U-shaped groove 3. The compression rate of the material of the first barb 7 and the connecting part 601 ranges from 5% to 30%. Based on the compression rate range, the compression deformation range of the first barb 7 and the connecting part 601 increases, which can make the clamping piece 6 adapt to grid clamping claws 9 of various sizes, thereby expanding the application range of the clamping strip while ensuring the pulling force.

[0064] In addition, in order to realize better intelligent control, the coating device also comprises a control assembly for controlling the glue coating route, the control assembly comprises an image acquisition module, a processing module and a control module, the image acquisition module, the processing module and the control module are electrically connected, the image acquisition module is located directly above the strip-shaped part 2, the image acquisition module is used for acquiring the actual image of the strip-shaped part 2 under the environment characteristics and transmitting the actual image of the strip-shaped part 2 to the processing module, wherein the environment characteristics refer to the macroscopic control of the entire strip and the surrounding equipment environment, the processing module and the control module are arranged on the base 19, the processing module generates the glue coating route according to the actual image of the strip-shaped part 2, and the control module controls the gantry sliding table module to work based on the glue coating route.

[0065] The processing module comprises:

[0066] An image correction submodule is configured to acquire an actual image of the strip-shaped component 2 collected by the image collection module, and perform error compensation processing on the actual image to obtain a corrected image. The corrected image has a clear definition and contains the complete length of the strip-shaped component 2, and meets the basic conditions for image analysis. The selection of the corrected image containing the complete length of the strip-shaped component 2 can provide a reference for the determination of the later gluing area.

[0067] An image analysis submodule is configured to perform extraction analysis on the obtained corrected image, to obtain the upper surface edge information of the strip-shaped component 2 to be coated, and to perform fitting calculation on the upper surface edge information of the strip-shaped component 2 to obtain the size of the strip-shaped component 2. Since the strip-shaped component 2 may have different sizes, the area to be coated during gluing is different for different sizes of the strip-shaped component 2. Therefore, the size of the strip-shaped component 2 needs to be accurately obtained. The fitting calculation method based on edge information can quickly obtain the actual size of the strip-shaped component 2, effectively avoiding the need for manual judgment or manual measurement, achieving intelligent judgment, improving efficiency, and reducing labor costs. Moreover, the obtained size information is convenient for storage and later checking or tracking reference use.

[0068] A gluing area determination submodule is configured to obtain the size information of the strip-shaped component 2, confirm the length and width values of the upper surface of the strip-shaped component 2, call the pre-existing standard coating sample library in the processing module, compare the size information of the strip-shaped component 2 with the samples in the standard coating sample library, call the one with the highest similarity to the size and shape of the strip-shaped component 2 as the standard coating reference sample, and determine the recommended coating area on the strip-shaped component 2 based on the standard coating reference sample. The standard coating sample library stores the gluing surfaces of strip-shaped components 2 with different shapes and sizes, and displays the most suitable recommended gluing area selected according to long-term practice on the gluing surface. The standard gluing sample library is updated in real time to obtain sufficient samples.

[0069] A gluing route determination submodule is configured to obtain the recommended coating area of the strip-shaped component 2, and determine the gluing area and gluing thickness according to the recommended coating area, thereby determining the gluing route.

[0070] A gluing route output submodule is configured to transmit the determined gluing route to the control module, and then control the gantry sliding table module to move to the corresponding position through the control module, and perform actual gluing according to the preset gluing route. This method avoids the need for real-time manual adjustment of the gantry sliding table module during gluing, and can quickly obtain a relatively accurate recommended gluing area. The mechanical work is performed in the recommended gluing area, achieving precise positioning and high efficiency.

[0071] Specifically, the image analysis submodule includes:

[0072] a region extraction module configured to extract the coating region and obtain a minimum rectangular region corresponding to the coating region, wherein the minimum rectangular region is a smallest rectangular region capable of containing the coating region;

[0073] a coordinate information acquisition module configured to extract coordinate information corresponding to an edge point set of an edge line of the coating region;

[0074] an edge point screening module configured to obtain two edge points farthest apart in a straight line in the coating region according to the coordinate information corresponding to the edge point set of the edge line of the coating region;

[0075] a start and end point determination module configured to take the two edge points farthest apart as a start point and an end point, respectively;

[0076] a first line segment acquisition module configured to extract a straight line segment between the start point and the end point and take the straight line segment between the start point and the end point as a reference line segment;

[0077] a second line segment acquisition module configured to extract four vertices of the minimum rectangular region and obtain line segments between the start point and the four vertices, and take the line segments between the start point and the four vertices as reference line segments;

[0078] an angle extraction module configured to extract an included angle between the reference line segment and the reference line segment;

[0079] a glue application path determination module configured to, after the start point and the end point are determined, take the glue application path as a first coating according to the edge line and fill glue to an uncoated region in the coating region after the first coating according to a unit glue application distance; wherein the unit glue application distance is obtained by the following formula:

[0080]

[0081]

[0082]

[0083] wherein L represents the unit glue application distance; h 01 and h 02 represent a first adjustment coefficient and a second adjustment coefficient; L max represents a straight line distance between the start point and the end point; S y represents an area of the coating region; S m represents an area of the minimum rectangular region; H m represents a glue thickness; H min represents a minimum thickness of glue capable of being sprayed by a coating device; α min and α maxa minimum value and a maximum value of an included angle between the reference line segment and the baseline segment.

[0084] The working principle and beneficial effects of the technical solution are as follows: the control assembly is used to control the work of the gantry sliding table module. Specifically, before the gantry sliding table module works, the coating area of the strip-shaped part 2 and the coating route are determined. The image acquisition module acquires the actual image of the strip-shaped part 2 by image acquisition of the position of the strip-shaped part 2, obtains the overall shape of the corresponding strip-shaped part 2, and transmits the acquired actual image of the strip-shaped part 2 to the processing module. After processing by the processing module, the coating route is generated. In the determination process of the coating route, the actual size of the strip-shaped part 2, including the length and the width, is fully considered to determine the total area. Then, the standard coating reference sample closest to the current strip-shaped part 2 is retrieved by comparison and analysis based on the pre-stored standard coating sample library, and the suggested coating area is obtained in combination with the coating area displayed on the standard coating reference sample. The coating area on the standard coating reference sample is determined based on a large amount of practical experience and is updated in real time to ensure that the suggested coating area meets the coating requirements. Finally, the coating route is determined based on the suggested coating area. After the coating route is determined, the control module controls the work of the gantry sliding table module based on the coating route, thereby improving the automation degree of the coating device and the installation efficiency. In addition, a good coating method can improve the sealing performance and reliability of the connection between the front windshield glass 5 and the strip, which has high practical value.

[0085] On the other hand, the region extraction module can accurately extract the coating region and find the smallest rectangular region that can completely contain the coating region. This ensures the accuracy and efficiency of subsequent operations. The coordinate information acquisition module and the edge point screening module can extract the edge point set of the edge line of the coating region and screen out the two edge points with the farthest straight line distance from them. These two points usually represent the longest diagonal of the coating region, providing an important reference for subsequent path planning. The first line segment acquisition module and the second line segment acquisition module determine the reference line segment between the starting point and the ending point and the reference line segment between the starting point and the four vertices of the smallest rectangular region, respectively. These line segments provide the basis for subsequent angle calculation and glue application path planning. The angle extraction module can calculate the included angle between the reference line segment and the reference line segment, and the glue application path determination module can plan the glue application path according to these information. This ensures that the glue application process can cover the entire coating area as evenly and efficiently as possible. The unit glue application distance calculation formula in the glue application path determination module takes into account multiple factors such as the area, shape of the coating area, glue thickness, and spraying capacity of the glue application device. This allows the glue application process to be intelligently adjusted according to specific conditions, thereby ensuring the quality and efficiency of the glue application. The entire glue application path determination process is automated and does not require human intervention. At the same time, through accurate region positioning, edge point screening, angle extraction, and intelligent adjustment of the unit glue application distance, this technology can optimize the glue application path, reduce waste during the glue application process, and improve the quality and efficiency of the glue application.
