Description

Technical Field

[0001] The utility model relates to the technical field of automobile sealing strip assembly, in particular to a rolling tool for an automobile sunroof sealing strip. Background Technique

[0002] An automobile sunroof sealing strip is a sealing component installed around the sunroof frame. Its main function is to prevent water, dust and noise from entering the vehicle through the connection gap of the sunroof. At the same time, when the sunroof is closed, it provides good airtightness and sound insulation for the vehicle interior environment. The basic structure of the automobile sunroof sealing strip includes a main sealing strip and an adhesive layer. When assembling the existing automobile sunroof sealing strip, the installer first assembles the main sealing strip at the edge of the sunroof frame through the adhesive layer, and then holds a roller to apply a pressing force to the main sealing strip, so that the main sealing strip is firmly adhered to the sunroof frame.

[0003] However, there are defects in the above installation method of applying a pressing force to the main sealing strip by using a roller. Among them, the magnitude of the pressing force depends on the pressure manually applied by the installer to the main sealing strip, which makes the pressing force received by the automobile sunroof sealing strip lack uniformity. Especially at the corners of the sunroof frame, due to the limitation of the flexibility of the installer's wrist, the pressing force received by the main sealing strip will drop sharply, resulting in a poor pasting effect between the main sealing strip and the sunroof frame, and further affecting the sealing effect.

[0004] After retrieval, a rolling device for an automobile sunroof sealing strip is disclosed in the Chinese patent document CN211163755U. The rolling device adaptively positions the sunroof through the elasticity of the support wheel and the spring, and presses the sunroof sealing strip through the rolling wheel, so that the sealing strip is effectively pasted to the vehicle body sheet metal. Then, the rolling wheel is driven by a motor to perform high-frequency and high-efficiency rolling pressing on the sunroof sealing strip. During the rolling pressing, the auxiliary wheel is used to ensure the direction control during rolling.

[0005] However, there are still defects in the actual use process of the above rolling device. For example, in the rolling channel formed between the auxiliary wheel and the support wheel, when the installer performs the rolling operation, the main sealing strip needs to be placed in the rolling channel. In order to ensure the guiding effect of the rolling channel, the designed size of the opening of the rolling channel is only slightly larger than the sheet metal thickness of the sunroof frame. In this way, the assembly and release process of the rolling device and the sunroof frame takes a lot of time for the rolling operation, reducing the assembly efficiency of the automobile sunroof sealing strip and affecting the production rhythm of the assembly line. Summary of the Invention

[0006] The purpose of the utility model is to provide a rolling tool during the assembly process of an automobile sunroof sealing strip, so as to reduce the assembly difficulty with the sunroof frame sheet metal, improve the assembly efficiency of the automobile sunroof sealing strip, and enhance the rolling effect.

[0007] In order to achieve the above purpose, the utility model adopts the following scheme:

[0008] A rolling tool for a car sunroof sealing strip comprises a rolling assembly, an auxiliary pressing assembly, a guide wheel assembly and a power device for driving the rolling assembly;

[0010] The guide wheel assembly is used to contact the sheet metal of the sunroof frame and form a support on the inner side of the sheet metal. A pair of guide wheel assemblies are arranged on the mounting seat. The pair of guide wheel assemblies are symmetrically arranged along the axis of the rolling wheel. A rolling channel for accommodating the automobile sunroof sealing strip is formed between the rolling wheel and the pair of guide wheel assemblies.

[0011] The auxiliary pressing assembly includes an auxiliary wheel, a connecting rod, a toggle rod and a bracket, wherein the bracket is installed on a sliding seat, the connecting rod is connected to the bracket through the toggle rod, the auxiliary wheel is located above the rolling channel, and the auxiliary wheel is installed at the end of the connecting rod.

[0012] Among them, the auxiliary pressing assembly has a closed state and an open state. When the auxiliary pressing assembly is in the closed state, the auxiliary wheel contacts the outer side of the sheet metal of the sunroof frame. When rolling the sealing strip of the automobile sunroof, the auxiliary wheel plays a limiting and guiding role above the rolling channel; when the auxiliary pressing assembly is in the open state, the auxiliary wheel moves along with the connecting rod in a direction away from the rolling channel under the drive of the toggle rod, which is conducive to releasing the assembly space above the rolling channel, thereby reducing the difficulty of assembling the rolling tool and the sheet metal of the sunroof frame.

[0013] Preferably, a sleeve is arranged on the outer side of the transmission shaft, the power device is connected to the sliding seat through the sleeve, and a gripping portion is arranged on the side wall of the sleeve. With such arrangement, the sleeve is convenient for the operator to hold, and then it is convenient to apply a gripping force to the sliding seat, which is conducive to driving the rolling wheel to move in a direction away from the guide wheel assembly, thereby expanding the rolling channel, making it convenient for the automobile sunroof sealing strip to enter the rolling channel, and further reducing the difficulty of assembling the rolling tool and the sheet metal of the sunroof frame.

[0014] Preferably, a handle is provided on one side of the sleeve, and the handle is connected to the bottom of the mounting seat. In this way, the handle serves as an extension structure of the bottom of the mounting seat, which is convenient for the operator to hold the rolling channel with one hand to expand.

[0015] Preferably, the mounting seat is provided with a screw structure for adjusting the preload force of the elastic component. With this arrangement, the expansion and contraction amount of the elastic component can be adjusted by twisting the screw structure, thereby adjusting the preload force, facilitating the assembly of sunroof sealing strips for automobiles of different models, and improving the versatility of the rolling tool.

[0016] Preferably, a first scale line is provided on the side wall of the mounting seat, and a second scale line corresponding to the first scale line is provided on the sliding seat. In this way, the relative position mark between the first scale line and the second scale line facilitates the operator to accurately adjust the preload force of the elastic component.

[0017] Preferably, a tension spring is provided between the connecting rod and the toggle rod, one end of the tension spring is mounted on the connecting rod, and the other end of the tension spring is mounted on the toggle rod. In this arrangement, the tension spring is used to apply a retaining force to the connecting rod, so that during the rolling process, the auxiliary wheel is kept in contact with the outer side of the sheet metal of the sunroof frame, thereby ensuring the effect of limiting guidance.

[0018] Preferably, the toggle lever is provided with a spherical handle, which is arranged in this way, so that the spherical handle is used to extend the length of the toggle lever, which is conducive to increasing the force arm of the toggle lever and plays a labor-saving role.

[0019] Preferably, the connection between the toggle rod and the ball handle is covered with a thermoplastic tube. In this way, the thermoplastic tube acts as a protective layer to form a smooth transition between the connection between the ball handle and the toggle rod.

[0020] Compared with the prior art, a rolling tool for an automotive sunroof sealing strip provided by the present utility model has the following substantial features and improvements: In the rolling tool for the automotive sunroof sealing strip, the design of the rolling assembly makes the rolling process more efficient. Through the elastic component arranged between the mounting seat and the sliding seat, the rolling wheel can automatically adapt to automotive sunroof sealing strips of different thicknesses, ensuring uniform pressure application, improving the installation quality of the sealing strip. A pair of symmetrically arranged guide wheel assemblies ensure that the rolling wheel maintains an accurate position during the rolling process, thereby reducing offset and error during rolling and improving the installation accuracy of the sealing strip. The auxiliary pressing assembly has a unique design with a closed state and an open state. In the closed state, the auxiliary wheel contacts the outer side of the sunroof frame sheet metal, playing a role of limiting and guiding to ensure the stability of the rolling process. In the open state, the auxiliary wheel moves away from the rolling channel along with the connecting rod, releasing the assembly space above the rolling channel. The open state of the auxiliary pressing assembly provides a larger assembly space for the operator, avoiding assembly difficulties caused by narrow space. This not only improves the assembly efficiency but also reduces the potential damage risk to the sunroof frame sheet metal. The overall design takes into account all details during the rolling process, ensuring uniform force and accurate position of the sealing strip during installation. Through precise guidance and flexible operation, the high-quality installation of the sealing strip is guaranteed, the rolling effect is improved, thereby enhancing the sealing performance and service life of the sunroof.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following will describe in detail the specific embodiments of the present utility model in conjunction with the accompanying drawings.

[0027] As Figures 1 - 4 shown, in the embodiment of the present utility model, a rolling tool for an automotive sunroof sealing strip is proposed, aiming to reduce the assembly difficulty with the sheet metal of the sunroof frame, improve the assembly efficiency of the automotive sunroof sealing strip, and enhance the rolling effect.

[0028] When the existing rolling device performs the rolling operation on the automotive sunroof sealing strip, the installer needs to place the main sealing strip in the rolling channel. In order to ensure the guiding effect of the rolling channel, the designed size of the opening of the rolling channel is only slightly larger than the thickness of the sheet metal of the sunroof frame. In this way, the assembly and release process of the rolling device and the sunroof frame takes a lot of time for the rolling operation, and during the assembly process, repeatedly adjusting the position of the rolling device is likely to pose a risk of damage to the sheet metal of the sunroof frame.

[0029] A rolling tool for an automotive sunroof sealing strip proposed in the embodiment of the present utility model, through the unique design of the auxiliary pressing and combining component 2, in the closed state, the auxiliary wheel 21 contacts the outer side of the sheet metal 18 of the sunroof frame, playing a role of limiting and guiding, ensuring the stability of the rolling process; in the open state, the auxiliary wheel 21 moves away from the rolling channel 19 along with the connecting rod 22, releasing the assembly space above the rolling channel 19. The open state of the auxiliary pressing and combining component 2 provides a larger assembly space for the operator, avoiding assembly difficulties caused by narrow space. This not only improves the assembly efficiency but also reduces the potential risk of damage to the sheet metal 18 of the sunroof frame. The overall design of this rolling tool takes into account various details during the rolling process, ensuring uniform force and accurate position of the sealing strip during installation. Through precise guiding and flexible operation, it guarantees the high-quality installation of the sealing strip, enhances the rolling effect, and thus improves the sealing performance and service life of the sunroof.

[0030] As Figure 1 shown, a rolling tool for an automotive sunroof sealing strip includes a rolling component 1, an auxiliary pressing and combining component 2, a guide wheel component 3, and a power device 4 for driving the rolling component 1. Driving the rolling component 1 by the power device 4 reduces the workload of manual operation and the fatigue degree of the operator. For example, the power device 4 is selected to be driven by electricity or pneumatic.

[0031] As Figure 2 Combined with Figure 4As shown in the figure, the rolling component 1 includes a mounting seat 11, a sliding seat 12, a rolling wheel 13, a transmission shaft 14, and an elastic component 15 for applying a pre-tightening force to the sliding seat 12. A guide rail 16 is provided on the side wall of the mounting seat 11. The sliding seat 12 is connected to the mounting seat 11 through the guide rail 16. The elastic component 15 is disposed between the mounting seat 11 and the sliding seat 12. The rolling wheel 13 is mounted on the sliding seat 12 through the transmission shaft 14. The transmission shaft 14 is connected to the output end of the power device 4. The pre-tightening force of the elastic component 15 is transmitted to the automotive sunroof sealing strip through the sliding seat 12, the transmission shaft 14, and the rolling wheel 13 in sequence, serving as the pressing force during the rolling process. For example, the elastic component 15 is selected as a compression spring.

[0032] As Figure 3 shown in combination with Figure 4 As shown in the figure, the guide wheel assembly 3 is used to contact the sheet metal 18 of the sunroof frame and form a support on the inner side of the sheet metal 18. A pair of guide wheel assemblies 3 are arranged on the mounting seat 11. The pair of guide wheel assemblies 3 are symmetrically arranged along the axis of the rolling wheel 13. A rolling channel 19 for accommodating the automotive sunroof sealing strip is formed between the rolling wheel 13 and the pair of guide wheel assemblies 3.

[0033] As Figure 4 shown in the figure, the auxiliary pressing assembly 2 includes an auxiliary wheel 21, a connecting rod 22, a toggle rod 23, and a bracket 24. The bracket 24 is mounted on the sliding seat 12. The connecting rod 22 is connected to the bracket 24 through the toggle rod 23. The auxiliary wheel 21 is located above the rolling channel 19, and the auxiliary wheel 21 is mounted at the end of the connecting rod 22.

[0034] As Figure 4 shown in the figure, a sleeve 5 is provided on the outer side of the transmission shaft 14. The power device 4 is connected to the sliding seat 12 through the sleeve 5. A holding portion is provided on the side wall of the sleeve 5. With such a setting, the sleeve 5 is used to facilitate the operator's grasping, and further facilitate applying a holding force to the sliding seat 12, which is beneficial to driving the rolling wheel 13 to move away from the guide wheel assembly 3, thereby expanding the rolling channel 19 and facilitating the automotive sunroof sealing strip to enter the rolling channel 19, and further reducing the assembly difficulty between the rolling tool and the sheet metal 18 of the sunroof frame.

[0035] Among them, a handle 6 is provided on one side of the sleeve 5. The handle 6 is connected to the bottom of the mounting seat 11. With such a setting, the handle 6 serves as an extended structure at the bottom of the mounting seat 11, facilitating the operator to hold it with one hand to expand the rolling channel 19.

[0036] The auxiliary pressing component 2 has a closed state and an open state. When the auxiliary pressing component 2 is in the closed state, the auxiliary wheel 21 is in contact with the outer side of the sheet metal 18 of the skylight frame. When rolling the automotive skylight sealing strip, the auxiliary wheel 21 plays a role of limiting and guiding above the rolling channel 19. When the auxiliary pressing component 2 is in the open state, the auxiliary wheel 21 moves away from the rolling channel 19 along with the connecting rod 22 under the drive of the toggle rod 23, which is beneficial to releasing the assembly space above the rolling channel 19, thereby reducing the assembly difficulty between the rolling tool and the sheet metal 18 of the skylight frame.

[0037] As Figure 1 shown, a spherical handle 7 is provided on the toggle rod 23. With such a setting, the spherical handle 7 is used to extend the length of the toggle rod 23, which is beneficial to increasing the force arm for adjusting the toggle rod 23 and plays a role of saving effort.

[0038] In order to further improve the protection effect of the toggle rod 23, the connection part between the toggle rod 23 and the spherical handle 7 is covered with a thermoplastic tube. With such a setting, the thermoplastic tube serves as a protective layer to make the connection part between the spherical handle 7 and the toggle rod 23 form a smooth transition.

[0039] As Figure 2 shown, a tension spring 25 is provided between the connecting rod 22 and the toggle rod 23. One end of the tension spring 25 is installed on the connecting rod 22, and the other end of the tension spring 25 is installed on the toggle rod 23. With such a setting, the tension spring 25 is used to apply a holding force to the connecting rod 22, so that during the rolling process, the auxiliary wheel 21 remains in contact with the outer side of the sheet metal 18 of the skylight frame, thereby ensuring the effect of limiting and guiding.

[0040] In order to further make the rolling tool adapt to the assembly process requirements of different automotive skylight sealing strips, as Figure 4 shown, a setscrew structure 17 for adjusting the pre-tightening force of the elastic member 15 is provided on the mounting seat 11. With such a setting, by turning the setscrew structure 17, the telescopic amount of the elastic member 15 can be adjusted, thereby realizing the adjustment of the pre-tightening force, facilitating the assembly of automotive skylight sealing strips for different vehicle models, and improving the versatility of the rolling tool.

[0041] As Figure 1 shown, a first scale line 8 is provided on the side wall of the mounting seat 11. A second scale line 9 corresponding to the first scale line 8 is provided on the sliding seat 12. With such a setting, through the relative position marking between the first scale line 8 and the second scale line 9, it is convenient for the operator to accurately adjust the pre-tightening force of the elastic member 15. For example, the rolling force required for the rolling process of the automotive skylight sealing strip is 80 - 100 N, and the rolling tool is calibrated. The relative position between the first scale line 8 and the second scale line 9 is adjusted to 8 - 9 mm, so that the pre-tightening force of the elastic member 15 meets the requirements of the required rolling force.

[0042] When the rolling tool for the automotive sunroof sealing strip proposed in the embodiment of the present utility model is in use, ensure that all components of the rolling tool (rolling wheel 13, guide wheel assembly 3, auxiliary pressing assembly 2, etc.) are intact and the power device 4 is operating normally. Clean the automotive sunroof frame and the sealing strip installation area to ensure there is no dust and impurities.

[0043] Pre-position the sealing strip, and initially install the automotive sunroof sealing strip at the predetermined position on the sunroof frame to ensure that the sealing strip is flat and without distortion.

[0044] The operator uses the toggle lever 23 to adjust the auxiliary pressing assembly 2 to the open state, so that the auxiliary wheel 21 moves away from the rolling channel 19 along with the connecting rod 22, releasing the assembly space above the rolling channel 19. Align the guide wheel assembly 3 with the sheet metal 18 of the sunroof frame to ensure that the guide wheel assembly 3 forms a support with the inner side of the sheet metal 18. The guide wheel assembly 3 should be symmetrically arranged along the axis of the rolling wheel 13 to provide stable guidance. Then adjust the auxiliary pressing assembly 2 to the closed state, so that the auxiliary wheel 21 contacts the outer side of the sheet metal 18 of the sunroof frame, and the auxiliary wheel 21 plays a role of limiting and guiding above the rolling channel 19.

[0045] Start the power device 4 to drive the transmission shaft 14 to drive the rolling wheel 13 to rotate. The operator holds the tool, aligns the rolling wheel 13 with the pre-positioned sealing strip, and slowly moves the rolling tool along the sunroof frame to ensure that the rolling wheel 13 applies pressure evenly, so that the sealing strip is firmly installed on the sunroof frame. The supporting role of the guide wheel assembly 3 ensures that the rolling wheel 13 remains stable during the rolling process, avoiding deviation and error.

[0046] After the rolling is completed, check the installation quality of the sealing strip to ensure that the sealing strip is flat and firm, and there is no part with missed rolling or insufficient pressing. If any part with poor installation is found, it can be adjusted by repeating the rolling operation until the sealing strip fully meets the requirements.

[0047] The present utility model is not limited to the specific technical solutions described in the above embodiments. In addition to the above embodiments, the present utility model can also have other implementation manners. For those skilled in the art, any technical solutions formed by making any modifications, equivalent replacements, improvements, etc. within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
