Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass guide rail technology, and in particular to a pre-positioning guide rail and vehicle glass. Background Technology
[0002] In the production of flush-mounted doors, traditional moisture curing processes are typically used. During the bonding and curing process, the guide rails and glass must be placed flat on the curing rack, resulting in low rack efficiency. Furthermore, workers must frequently squat down when laying the glass flat, leading to high labor intensity. Moreover, if the guide rails are touched during handling, the position between the rails and the glass will shift, causing the product dimensions to exceed tolerance requirements. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a pre-positioning guide rail and vehicle glass so that the position does not shift when the guide rail and glass are bonded and cured.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A pre-positioning guide rail includes: The guide rail body has at least one positioning element at each end of its length direction; An adhesive component is disposed on the guide rail body and on the left and / or right side of the positioning component in the length direction; An adhesive is disposed on the guide rail body along the length direction of the guide rail body.
[0005] Furthermore, at least two sets of positioning elements are provided at both ends of the guide rail body in the length direction.
[0006] Furthermore, each set of positioning elements includes two positioning protrusions disposed opposite each other in the width direction of the guide rail body; there is a gap between the two positioning protrusions.
[0007] Furthermore, the gaps formed by all the positioning elements are on the same straight line; the adhesive is disposed along the straight line.
[0008] Furthermore, the distance between the adhesive and the bonded component is less than 1 mm.
[0009] Furthermore, the adhesive component includes tape.
[0010] Furthermore, the length of the tape is 14.5mm-15.5mm; the width of the tape is 5.5mm-6.5mm.
[0011] Furthermore, the tape is parallelogram-shaped.
[0012] Furthermore, in the thickness direction of the guide rail body, the thickness of the tape is 0.2mm-0.3mm higher than the height of the positioning member.
[0013] A vehicle glass includes a glass body and a prepositioning guide as described above.
[0014] The beneficial effects of this utility model are as follows: the positioning component marks the position where the adhesive component needs to be pasted, thereby positioning the adhesive component; and the adhesive is placed on the guide rail body along the length of the guide rail body, so that the adhesive can effectively bond the guide rail to the glass and other structures, and then bond the adhesive component to the glass and other structures, ensuring that the position between the guide rail and the glass and other structures will not shift before the adhesive and the glass and other structures are bonded and cured. This can maintain the production efficiency of guide rail installation on the production line, and effectively reduce the problem of mismatch between the glass and other structures and the guide rail surface, which causes defects in fit or size.

[0016] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0017] To overcome the problems of existing technologies that require the guide rail and glass to be placed flat on the curing rack, resulting in low curing rack efficiency, and the issue that touching the guide rail during product handling can cause positional changes between the guide rail and glass, leading to product dimensions exceeding tolerance requirements, this utility model discloses a pre-positioning guide rail. By incorporating positioning and adhesive components on the guide rail as a pre-positioning device, the guide rail is firmly bonded to the glass, preventing misalignment and improving both curing rack efficiency and production efficiency. Simultaneously, it ensures that the fit between the guide rail and glass is well-matched (the guide rail is a slender injection molded part, requiring surface fluctuation > 0.5mm, and the product requires guide rail height direction fluctuation ≤ ±0.25mm), and guarantees the bonding performance / weather resistance of the glass and guide rail assembly, as well as the dimensional accuracy and fit of the assembly (including guide rail position) (positional tolerance ≤ ±0.75mm), enabling rapid guide rail positioning and ensuring dimensional precision.
[0018] This application uses the production of flush-mounted door vehicle guide rails as an example to introduce the structure and usage of the pre-positioning guide rail. The pre-positioning guide rail provided in this application is not only applicable to the production of flush-mounted door vehicle guide rails, but also to various other guide rail production scenarios. For example, the pre-positioning device can also be extended to plastic or metal supports for vertically cured glass at room temperature, such as windshield brackets. The specific structure and usage of the pre-positioning guide rail are as follows: A pre-positioning guide rail includes: a guide rail body 1, wherein at least one positioning element 11 is provided at both ends of the guide rail body 1 in the length direction; an adhesive element 2, which is disposed on the guide rail body 1 and on the left and / or right side of the positioning element 11 in the length direction; and an adhesive 3, which is disposed on the guide rail body 1 along the length direction of the guide rail body 1. By setting a positioning element 11 on the guide rail body 1, the positioning element 11 marks the position where the adhesive part 2 needs to be pasted, thereby positioning the adhesive part 2; and by setting the adhesive 3 along the length direction of the guide rail body 1 on the guide rail body 1, the adhesive 3 can effectively bond the guide rail to the glass and other structures, and then bond the adhesive part 2 to the glass and other structures. This ensures that after the guide rail is placed on the curing rack, the position between the guide rail and the glass and other structures will not shift before the adhesive 3 and the glass and other structures are bonded and cured. This can maintain the production efficiency of guide rail installation on the production line, and effectively reduce the problem of mismatch between the glass and other structures and the guide rail surface, which may cause defects in fit or size.
[0019] In some embodiments, the guide rail body 1 has at least two sets of positioning members 11 at both ends in the length direction. By providing multiple sets of positioning members 11 in the length direction of the guide rail body 1, multiple adhesive members 2 can be positioned, thereby enabling multiple adhesive members 2 to be provided on the guide rail body 1, which improves the stability of the connection between the guide rail and the glass and prevents displacement between the guide rail and the glass.
[0020] In some embodiments, each set of positioning members 11 includes two positioning protrusions 111 disposed opposite to each other in the width direction of the guide rail body 1; there is a gap between the two positioning protrusions 111. By having the two positioning protrusions 111 disposed opposite to each other in the width direction and forming a gap between the two positioning protrusions 111, the bonding position of the adhesive member 2 can be positioned by using the gap as an identifier, thereby improving the positioning accuracy of the adhesive member 2.
[0021] In some embodiments, the gaps formed by all positioning elements are on the same straight line; the adhesive 3 is arranged along a straight line. By setting the gaps between the positioning protrusions 111 on the guide rail body 1 on the same straight line, the gaps between the positioning protrusions 111 in each positioning element 11 guide the application of the adhesive 3, so that the adhesive 3 is applied in a preset direction, avoiding the adhesive 3 from overflowing while improving the bonding effect of the adhesive 3 to the guide rail and the glass.
[0022] In some embodiments, the distance between the adhesive 3 and the adhesive component 2 is less than 1 mm. By setting the distance between the adhesive 3 and the adhesive component 2 to less than 1 mm, that is, the adhesive 3 can cover the adhesive component 2, it is ensured that when the adhesive 3 is pressed, the adhesive can contact the adhesive component 2, so that the space between the guide rail and the glass is filled by the adhesive 3 and the adhesive component 2, without gaps or air leakage.
[0023] In some embodiments, the adhesive 2 includes adhesive tape. Using adhesive tape as the adhesive 2 allows for effective connection between the guide rail and the glass; the adhesive tape may be of the S&K 910GT type. In other alternative embodiments, hot melt adhesive may be used as the adhesive 2.
[0024] In some embodiments, the tape is 14.5mm-15.5mm long and 5.5mm-6.5mm wide. By setting the tape length to 14.5mm-15.5mm and the width to 5.5mm-6.5mm, the initial bonding force between the guide rail and the glass is greater than 200N, ensuring that the guide rail will not shift its position relative to the glass after being placed on the curing rack.
[0025] In some embodiments, the thickness of the tape in the thickness direction of the guide rail body 1 is 0.2mm-0.3mm higher than the height of the positioning member 11. Simultaneously, the tape is shaped as a parallelepiped, allowing it to both serve a pre-positioning function and ensure compatibility with the bonding process, reducing overlap and excess adhesive, and ensuring a seamless connection between the guide rail and the glass, preventing air or water leakage.
[0026] In some embodiments, adhesive 3 includes polyurethane adhesive. Using polyurethane adhesive as a bonding agent allows for effective bonding of the guide rail and glass after curing.
[0027] The following embodiments are preferred embodiments of the above implementation methods.
[0028] Please refer to Figures 1 to 5 A pre-positioning guide rail includes a guide rail body 1, on which a positioning element 11 is provided; an adhesive element 2, which is disposed on the guide rail body 1 and corresponds to the position of the positioning element 11; and an adhesive 3, which is disposed on the guide rail body 1 along the length direction of the guide rail body 1.
[0029] The guide rail body 1 has at least two sets of positioning elements 11 along its length. Each positioning element 11 includes two positioning protrusions 111 arranged opposite each other along the width of the guide rail body 1. There is a gap between the two positioning protrusions 111, and the gap between all positioning protrusions 111 is on the same straight line, allowing the adhesive 3 to be positioned along this straight line. The specific method of forming the positioning protrusions 111 includes designing pre-positioning marking lines and positioning protrusions 111 before the guide rail is molded, thereby controlling the accuracy of the manual bonding position of the tape on each guide rail to ±1mm. Figure 1 as well as Figure 5 As shown, six sets of positioning members 11 are provided along the length of the guide rail body 1. Among them, adhesive members 2 can be provided at both ends and the middle along the length of the guide rail body 1. By providing adhesive members 2 at multiple positions, the stability between the guide rail and the glass can be improved.
[0030] Adhesive component 2 includes adhesive tape; the tape requires 25-35 seconds to achieve optimal adhesion, significantly less than the curing time of adhesive 3. When determining the shape, size, and thickness of the tape, it is necessary to design different shapes, sizes, and thicknesses of the positioning tape based on the operator's habits. For example... Figure 2 As shown, in this embodiment, the tape is designed to be a parallelogram shape with a length of 14.5mm-15.5mm and a width of 5.5mm-6.5mm. This ensures that the initial bonding force between the guide rail and the glass is greater than 200N, guaranteeing that the guide rail will not shift its position relative to the glass after being placed on the curing rack.
[0031] The adhesive 3 includes polyurethane adhesive. When applying the polyurethane adhesive, the distance between the adhesive 3 and the bonding component 2 is less than 1mm. The adhesive 3 can also be applied to the bonding component 2, for example, with a length of 3mm, to ensure that the polyurethane adhesive can contact the tape after the guide rail is pressed. At the same time, the thickness of the tape is 0.2mm-0.3mm higher than the height of the positioning component 11, so that the polyurethane adhesive and tape fill the gap between the guide rail and the glass completely, without gaps or air leakage.
[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
