[0002] With the development of technology, vehicles are playing an increasingly important role in people's lives. As an important component of a vehicle, the windshield not only provides the driver and passengers with a clear view but also plays multiple roles such as protecting the safety of occupants, sound insulation, and heat insulation. To ensure the sealing effect of the windshield, adhesive strips are usually applied to it. However, existing adhesive strips are mainly applied manually, which has technical problems such as poor reliability and large positional errors.

[0003] Therefore, it is necessary to provide a new clamping tool to solve the above-mentioned technical problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a clamping fixture, which aims to solve the technical problems of poor reliability and large positional error of the adhesive strip caused by the manual pasting of adhesive strips in the prior art.

[0005] To achieve the above objectives, this utility model proposes a clamping fixture for installing rubber strips on windshields, the clamping fixture comprising:

[0006] support;

[0007] A positioning element, wherein the positioning element is disposed on the bracket, and the positioning element includes a rotating positioning wheel;

[0008] A pressure roller is rotatably mounted on the bracket. The outer circumferential surface of the pressure roller can abut against the rubber strip, and the rotation axis of the pressure roller is either intersected or opposite to the rotation axis of the positioning roller.

[0009] A feeding block is disposed on one side of the pressing wheel and is used to feed the rubber strip to the pressing wheel;

[0010] When installing the rubber strip of the windshield, the positioning wheel abuts against the side of the windshield and moves along the circumference of the windshield, and the pressing wheel abuts against the rubber strip and presses the rubber strip.

[0011] In one embodiment, the rotation axis of the pressing wheel is arranged in opposite directions to the rotation axis of the positioning wheel, and the rotation axis of the pressing wheel and the rotation axis of the positioning wheel are perpendicular to each other.

[0012] In one embodiment, the positioning member further includes an adjusting rod and a rotating shaft. The adjusting rod is movably disposed on the bracket, and the rotating shaft is disposed at the end of the adjusting rod away from the bracket. The positioning wheel is rotatably disposed on the rotating shaft, and the adjusting rod can drive the positioning wheel to move along its axial direction toward or away from the pressing wheel.

[0013] In one embodiment, the adjusting rod is a lead screw, and the lead screw is provided with two locking blocks, which respectively abut against two opposite sides of the bracket.

[0014] In one embodiment, a limit block is provided at the end of the rotating shaft away from the adjusting rod.

[0015] In one embodiment, the positioning wheel is provided with a receiving groove for accommodating the windshield.

[0016] In one embodiment, the inner wall of the receiving groove is arc-shaped.

[0017] In one embodiment, the feeding block is provided with a feeding hole at the position where the outer circumferential surface of the pressing wheel abuts against the rubber strip.

[0032] As a crucial component of a vehicle, the windshield not only provides the driver and passengers with visibility but also plays multiple roles, including protecting occupants, providing sound insulation, and heat insulation. To ensure a tight seal, waterproof strips are typically applied to the windshield. In actual production, researchers have found that the application of these strips is primarily done manually. However, due to the continuous feeding and pressing required during application, relying solely on manual positioning and application easily leads to technical problems such as misalignment and insecure adhesion of the strips.

[0033] This utility model proposes a clamping fixture, which aims to solve the technical problems of poor reliability and large positional error of adhesive strips caused by manual pasting.

[0034] Please see Figure 1 and Figure 2 In one embodiment of this utility model, a clamping fixture is used to install the rubber strip of a windshield. The clamping fixture includes a bracket 100, a positioning member 200, a clamping wheel 300, and a feeding block 400. The positioning member 200 is disposed on the bracket 100 and includes a rotating positioning wheel 210. The clamping wheel 300 is rotatably disposed on the bracket 100, and its outer circumferential surface can abut against the rubber strip. The rotation axis of the clamping wheel 300 is intersected or non-plane with the rotation axis of the positioning wheel 210. The feeding block 400 is disposed on one side of the clamping wheel 300 and is used to feed the rubber strip to the clamping wheel 300. When installing the rubber strip of the windshield, the positioning wheel 210 abuts against the side of the windshield and moves along the circumference of the windshield, while the clamping wheel 300 abuts against the rubber strip and clamps the rubber strip.

[0035] The technical solution of this utility model uses a positioning wheel 210 to position the adhesive strip conveyed by the feeding block 400, which makes the adhesive strip's bonding position more accurate. Simultaneously, the pressing wheel 300 presses the adhesive strip firmly against the inner end face of the windshield, making the adhesive strip's bonding more secure. In other words, using this pressing fixture to bond the adhesive strip to the windshield improves the accuracy and reliability of the adhesive strip's placement. In this embodiment, the positioning wheel 210 abuts against the side of the windshield and moves circumferentially along the windshield, positioning the adhesive strip conveyed by the feeding block 400 so that the feeding block 400 conveys the adhesive strip to the designated position. The pressing wheel 300 presses the adhesive strip firmly against the inner end face of the windshield. The feeding block 400 conveys the adhesive strip so that the pressing wheel 300 can press the adhesive strip firmly. Specifically, during windshield installation, the worker first places the adhesive strip on the feeding block 400, allowing it to be conveyed to the designated position. Then, the outer circumferential surface of the positioning wheel 210 is pressed against the side of the windshield, applying force towards the windshield to drive the clamping wheel 300 to press the adhesive strip. Finally, the positioning wheel 210 is driven to move circumferentially along the windshield, thus adhering the adhesive strip to the designated position on the inner end face of the windshield. Using this clamping fixture, the worker can more accurately and securely adhere the adhesive strip to the windshield. This clamping fixture is applied in the field of vehicle assembly technology.

[0036] It should be noted that the windshield has an inner end face, an outer end face, and sides around its perimeter. During installation, the inner end face faces inwards from the vehicle, and the outer end face faces outwards. When attaching the adhesive strip to the windshield, the strip is attached to the inner end face, and all parts of the strip should be equidistant from the edge of the windshield. Before installing the adhesive strip, the worker needs to apply an appropriate adhesive, such as glue, to the windshield to ensure effective adhesion. In this embodiment, the adhesive strip is attached to a designated position on the inner end face of the windshield. This designated position refers to the location of the adhesive strip after it has been attached, where all parts of the strip are equidistant from the edge of the windshield.

[0037] In one embodiment of this invention, the rotation axis of the pressing wheel 300 is coplanar with the rotation axis of the positioning wheel 210, and the rotation axis of the pressing wheel 300 is perpendicular to the rotation axis of the positioning wheel 210. Specifically, the coplanarity of the rotation axes of the pressing wheel 300 and the positioning wheel 210 ensures that when the positioning wheel 210 abuts against the side of the windshield, the pressing wheel 300 can abut against the rubber strip and press the rubber strip to the inner end face of the windshield. The perpendicularity of their rotation axes facilitates the worker in applying force and pressing the rubber strip firmly. In another embodiment of this invention, the rotation axis of the pressing wheel 300 and the rotation axis of the positioning wheel 210 are intersected, and the rotation axis of the pressing wheel 300 is perpendicular to the rotation axis of the positioning wheel 210.

[0038] Please see Figure 2 and Figure 3 In one embodiment of this utility model, the positioning member 200 further includes an adjusting rod 220 and a rotating shaft 230. The adjusting rod 220 is movably disposed on the bracket 100, and the rotating shaft 230 is disposed at the end of the adjusting rod 220 away from the bracket 100. The positioning wheel 210 is rotatably disposed on the rotating shaft 230, and the adjusting rod 220 can drive the positioning wheel 210 to move along its axial direction toward or away from the pressing wheel 300. Specifically, the adjusting rod 220 can move the positioning wheel 210 along its axial direction to adjust the distance between the positioning wheel 210 and the pressing wheel 300 in the axial direction of the positioning wheel 210, thereby ensuring that the worker can press the rubber strip tightly onto the inner end face of the windshield. Specifically, when installing the rubber strip of the windshield, the worker can adjust the position of the positioning wheel 210 according to the thickness of the rubber strip, thereby ensuring that the pressing wheel 300 can better abut against the rubber strip and press the rubber strip tightly onto the inner end face of the windshield.

[0039] Please see Figure 2 and Figure 3 In one embodiment of this utility model, the adjusting rod 220 is a lead screw 221, and two locking blocks 2211 are provided on the lead screw 221. The two locking blocks 2211 abut against two opposite sides of the bracket 100. In this embodiment, the locking blocks 2211 are nuts. The position of the positioning wheel 210 is adjusted by means of transmission through the lead screw 221, which has the characteristics of simple structure and convenient manufacturing, and can reduce the manufacturing difficulty of the clamping fixture. The two locking blocks 2211 provided on the lead screw 221 can abut against two opposite sides of the bracket 100 to lock the position of the lead screw 221, thereby locking the position of the positioning wheel 210, reducing the risk of the positioning wheel 210 shifting position when the adhesive strip is applied. In addition, the adjusting rod 220 can also be a slide rod, and the locking blocks 2211 can be locking screws.

[0040] Please see Figure 2In one embodiment of this utility model, a limiting block 231 is provided at the end of the rotating shaft 230 away from the adjusting rod 220. In this embodiment, the limiting block 231 can abut against the positioning wheel 210 to limit the position of the positioning wheel 210 and reduce the risk of the positioning wheel 210 disengaging from the rotating shaft 230.

[0041] In one embodiment of this utility model, the positioning wheel 210 is provided with a receiving groove 211 for accommodating the windshield. Specifically, when applying the adhesive strip, placing the windshield in the receiving groove 211 of the positioning wheel 210 can improve the positioning effect of the positioning wheel 210 on the adhesive strip conveyed by the conveyor block, so that the feeding block 400 can convey the adhesive strip to the designated position; at the same time, it can also reduce the risk of the positioning wheel 210 slipping off the windshield.

[0042] In one embodiment of this utility model, the inner wall of the receiving groove 211 is arc-shaped. Specifically, the side of the windshield is usually arc-shaped, and setting the inner wall of the receiving groove 211 to be arc-shaped can improve the positioning effect; at the same time, it can also reduce the risk of the windshield being damaged by the positioning wheel 210.

[0043] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the feeding block 400 is provided with a feeding hole 410 corresponding to the position where the outer circumferential surface of the pressing wheel 300 abuts against the adhesive strip. In this embodiment, the feeding hole 410 serves a guiding function, guiding the conveyed adhesive strip. Specifically, when conveying the adhesive strip, the adhesive strip is passed through the feeding hole 410, which positions the adhesive strip so that the feeding block 400 conveys the adhesive strip to the designated position when pasting the adhesive strip. In a specific embodiment, the feeding hole 410 can be a square hole or a round hole, and to reduce wear on the adhesive strip, chamfers or rounded corners can be provided at both ends of the feeding hole 410. In addition, the adhesive strip can also be guided by opening slots or other methods on the feeding block 400.

[0044] In one embodiment of this utility model, the bracket 100 is provided with a gripping part 110. Specifically, the gripping part 110 provides a grasping area for the worker to grip. By providing the gripping part 110 for the worker to grip, the operational difficulty for the worker when using the clamping tool to apply adhesive strips can be reduced.

[0045] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
