Description

Technical Field

[0001] This invention belongs to the field of automotive glass technology, and particularly relates to adhesive strip bonding tooling and automotive glass production lines. Background Technology

[0002] Currently, the application of adhesive strips (such as sealing strips and decorative strips) to the edges of glass panels is typically done manually. During this process, workers manually guide the strip along the glass edge while applying pressure to secure it to the glass surface using adhesive connectors. However, this method has the following drawbacks: manual operation makes it difficult to ensure the strip extends in the intended direction; the strip is prone to twisting and shifting during application, resulting in the installation position deviating from the preset dimensions and inconsistent adhesion quality.

[0003] To address the aforementioned issues, some existing technologies have introduced auxiliary adhesive bonding fixtures. However, these fixtures are typically complex in structure, containing multiple linkage mechanisms or drive components. They are not only costly to manufacture but also cumbersome to operate, requiring professional personnel for debugging and use. They are not convenient for rapid on-site operations and cannot meet the demands for efficient, stable, and precise adhesive bonding. Summary of the Invention

[0004] The purpose of this application is to provide a tooling for bonding adhesive strips and an automotive glass production line, which aims to improve the bonding quality between adhesive strips and glass, and is simple to operate and highly efficient.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, a tooling for bonding adhesive strips is provided for bonding adhesive strips to the edge of a glass panel. An adhesive element is provided between the adhesive strip and the panel. The tooling includes: a sliding plate for sliding along the edge of the panel under external force, the sliding plate having a limiting surface facing the adhesive strip; and a limiting plate stacked above and connected to the sliding plate for synchronous movement with the sliding plate. The limiting plate includes an extension and a limiting portion, the extension extending from the limiting portion... The extension extends above the plate surface. The limiting portion is connected to the end of the extension portion away from the limiting surface. The limiting portion and the limiting surface are arranged at intervals to form a limiting space between the limiting portion and the limiting surface for the adhesive strip to pass through. The limiting space is used to guide the adhesive strip to extend along the moving direction of the limiting plate during the movement of the limiting plate. The extension portion has a pressing surface facing the plate surface. The pressing surface is used to press down the adhesive strip to adhere the adhesive strip to the plate surface.

[0006] In some embodiments, the sliding plate includes a first plate and a second plate stacked on top of the first plate, and the limiting plate is stacked on top of the second plate; the glass has a side surface connected to the plate surface, the first plate is used to abut against the side surface and is slidable along the extension direction of the side surface, and the sidewall of the second plate facing the adhesive strip is configured as the limiting surface.

[0007] In some embodiments, the position of the second plate relative to the first plate is adjustable along the interval direction between the limiting portion and the limiting surface, and the position of the limiting plate relative to the second plate is also adjustable.

[0008] In some embodiments, the first plate is provided with a connecting hole, the second plate is provided with a first waist-shaped hole corresponding to the position of the connecting hole, and the limiting plate is provided with a second waist-shaped hole corresponding to the position of the connecting hole. Both the first waist-shaped hole and the second waist-shaped hole extend along the interval direction between the limiting portion and the limiting surface. The adhesive strip bonding fixture further includes a fastener, which is used to sequentially pass through the second waist-shaped hole, the first waist-shaped hole and the connecting hole to lock the limiting plate, the second plate and the first plate.

[0009] In some embodiments, the connecting hole, the first waist-shaped hole, and the second waist-shaped hole are arranged in multiples at intervals along the spacing direction between the limiting portion and the limiting surface, and each connecting hole, each first waist-shaped hole, and each second waist-shaped hole corresponds to one another.

[0010] In some embodiments, the first plate has a protrusion at one end edge facing the glass. The protrusion protrudes from the surface of the first plate along the thickness direction of the first plate and is used to abut against the second plate to limit the movement of the second plate relative to the first plate.

[0011] In some embodiments, the first plate, the second plate, and the limiting plate are made of plastic.

[0012] In some embodiments, along the thickness direction of the glass, the height of the pressing surface is less than the height of the contact surface between the sliding plate and the limiting plate.

[0013] In some embodiments, the limiting portion has an abutting surface facing the limiting surface, the abutting surface being used to abut the adhesive strip, and the pressing surface being connected to the abutting surface at one end away from the limiting surface.

[0014] Secondly, an automotive glass production line is provided, which includes the aforementioned adhesive strip bonding fixture.

[0015] In the adhesive strip bonding fixture provided in this application, the width direction of the adhesive strip is limited by the sliding plate sliding along the edge of the glass surface and the limiting space formed between the upper limit part of the limiting plate and the limiting surface of the sliding plate. As the limiting plate moves along the edge of the glass surface, the limiting space continuously constrains the adhesive strip, so that the adhesive strip is always limited to extending along the preset bonding trajectory. At the same time, the pressing surface of the extension part presses down on the adhesive strip simultaneously as the adhesive strip is limited and guided, and continuously presses the adhesive strip onto the glass surface. Therefore, the limiting and pressing actions are completed simultaneously during one sliding process of the tooling. This ensures that the distance between the adhesive strip and the glass edge is precisely controllable, and that the pressure on the adhesive strip is consistent throughout, preventing localized areas of poor adhesion or lifting. This improves the bonding quality between the adhesive strip and the glass through the adhesive component. In addition, this application only requires two layers of plate-shaped components, a sliding plate and a limiting plate, stacked together. There is no need for complex drive mechanisms or linkage components. During operation, simply place the tooling on the edge of the glass and push it to slide along the edge to simultaneously complete the limiting guidance and pressing of the adhesive strip. The operation is simple and efficient. Attached Figure Description

[0023] Please see Figures 1 to 5 This application provides an adhesive strip bonding fixture for bonding an adhesive strip 300 to the edge of the surface 210 of a glass 200. An adhesive member 400 is provided between the adhesive strip 300 and the surface 210. The adhesive strip bonding fixture includes: a sliding plate 10 for sliding along the edge of the surface 210 under external force, the sliding plate 10 having a limiting surface 122 facing the adhesive strip 300; and a limiting plate 20, stacked above and connected to the sliding plate 10, to move synchronously with the sliding plate 10; the limiting plate 20 includes an extension 21 and a limiting portion 22. 1. Extending from the limiting surface 122 to above the plate surface 210, the limiting part 22 is connected to one end of the extension part 21 away from the limiting surface 122. The limiting part 22 and the limiting surface 122 are arranged at intervals to form a limiting space 500 between the limiting part 22 and the limiting surface 122 for the adhesive strip 300 to pass through. The limiting space 500 is used to guide the adhesive strip 300 to extend along the moving direction of the limiting plate 20 during the movement of the limiting plate 20. The extension part 21 has a pressing surface 211 facing the plate surface 210. The pressing surface 211 is used to press down the adhesive strip 300 to bond the adhesive strip 300 to the plate surface 210.

[0024] The adhesive strip bonding fixture of this application is mainly used to attach adhesive strips 300 to the edge of the panel 210 of glass 200. Double-sided adhesive or other types of adhesives 400 are pre-placed between the adhesive strip 300 and the panel 210 of glass 200. Glass 200 is usually flat and has two opposing large surfaces, namely the panel 210. The adhesive strip 300 needs to be attached to the edge area of ​​the panel 210, and the distance between the inner side of the adhesive strip 300 and the edge of the panel 210 of glass 200 is required to be controlled within a preset range.

[0025] The adhesive strip bonding fixture comprises two main parts: a sliding plate 10 and a limiting plate 20. During use, the sliding plate 10 is placed beside the glass 200 and can slide along the extension direction of the glass 200 edge under external force. This sliding can be achieved by the sliding plate 10 directly contacting and sliding against the side wall of the glass 200, or by a guide structure on the sliding plate 10 engaging with the side wall of the glass 200. The sliding plate 10 has a limiting surface 122 facing the side where the adhesive strip 300 is located. The limiting surface 122 can be a flat side wall surface of the sliding plate 10, used to limit the adhesive strip 300 on one side of its width.

[0026] The extension 21 extends outward from the side where the limiting surface 122 of the sliding plate 10 is located, passing over the side wall of the glass 200, and extending all the way to the top of the plate surface 210 of the glass 200. The limiting part 22 is connected to the end of the extension 21, that is, the end of the extension 21 away from the limiting surface 122. A certain gap is formed between the limiting part 22 and the limiting surface 122. This gap is the limiting space 500 through which the adhesive strip 300 passes. The direction of the gap between the limiting part 22 and the limiting surface 122 is along the direction of the plate surface 210 of the glass 200. That is to say, when the glass 200 is placed horizontally, the limiting part 22 and the limiting surface 122 are opposite each other in the horizontal direction. Thus, when the adhesive strip 300 passes through the limiting space 500, the width direction of the adhesive strip 300 is sandwiched between the limiting part 22 and the limiting surface 122, and the adhesive strip 300 cannot move freely in the width direction.

[0027] When the adhesive strip bonding fixture slides along the side wall of the glass 200 under external force, the adhesive strip 300 will not twist or deviate under the constraint of the limiting space 500. Instead, it will extend forward continuously along the moving direction of the fixture, thus ensuring that the adhesive strip 300's bonding trajectory on the glass 200 surface 210 is a preset trajectory, and the distance between the side of the adhesive strip 300 and the side wall of the glass 200 remains consistent. Furthermore, as the adhesive strip bonding fixture moves along the edge of the glass 200, the pressing surface 211 continuously presses down on the adhesive strip 300, applying uniform pressure to the adhesive strip 300, so that the adhesive strip 300 is tightly adhered to the glass 200 surface 210 through double-sided adhesive or other adhesives 400.

[0028] In the adhesive strip bonding fixture provided in this application, the sliding plate 10 slides along the edge of the glass 200 surface 210, and the limiting space 500 formed between the upper limit portion 22 of the limiting plate 20 and the limiting surface 122 of the sliding plate 10 limits the width direction of the adhesive strip 300. During the movement of the limiting plate 20 along the edge of the glass 200 surface 210, the limiting space 500 continuously constrains the adhesive strip 300, so that the adhesive strip 300 is always limited to extending on the preset bonding trajectory. At the same time, the pressing surface 211 of the extension portion 21 presses down on the adhesive strip 300 simultaneously while the adhesive strip 300 is limited and guided, and continuously presses the adhesive strip 300 onto the glass 200 surface 210. Therefore, the limiting and pressing actions are completed simultaneously during one sliding process of the tooling. This ensures that the distance between the adhesive strip 300 and the edge of the glass 200 is precisely controllable, and that the pressure on the adhesive strip 300 is consistent throughout, without any localized poor adhesion or lifting. This improves the bonding quality of the adhesive strip 300 to the glass 200 via the adhesive component 400. In addition, this application only requires two layers of plate-shaped components, the sliding plate 10 and the limiting plate 20, to be stacked. There is no need for complex drive mechanisms or linkage components. During operation, simply place the tooling on the edge of the glass 200 and push it to slide along the edge to simultaneously complete the limiting guidance and pressing of the adhesive strip 300. The operation is simple and efficient.

[0029] In some embodiments, such as Figure 1 and Figure 2 As shown, the sliding plate 10 includes a first plate 11 and a second plate 12 stacked on top of the first plate 11, and a limiting plate 20 stacked on top of the second plate 12; the glass 200 has a side surface 220 connecting the plate surface 210, the first plate 11 is used to abut against the side surface 220 and can slide along the extending direction of the side surface 220, and the side wall of the second plate 12 facing the adhesive strip 300 is configured as a limiting surface 122.

[0030] The sliding plate 10 is designed as a split structure, consisting of a first plate 11 and a second plate 12 stacked on top of the first plate 11, while the limiting plate 20 is stacked on top of the second plate 12. The three plates are arranged in a stacked manner, resulting in a compact structure, and each plate can be independently processed and assembled as needed.

[0031] The first plate 11 is located beside the side 220 of the glass 200 during use, directly contacting and abutting against the side 220. When the operator applies external force to push the tooling, the first plate 11 slides along the extending direction of the side 220 of the glass 200. The inner side 220 of the first plate 11 can be a flat surface to form a surface contact with the side 220 of the glass 200, thereby ensuring the smoothness of the sliding process. Wear-resistant pads or rolling elements can also be provided on the inner side 220 of the first plate 11 to reduce sliding friction and make the tooling push smoother and less labor-intensive.

[0032] In this embodiment, a separate first plate 11 and a second plate 12 are provided. A limiting surface 122 is formed on the side of the second plate 12 facing the adhesive strip 300. The first plate 11 abuts against the side 220 of the glass 200 and slides along the side 220, providing a sliding guide for the entire tooling and ensuring that the tooling always moves along the edge of the glass 200. The limiting surface 122 is independently provided on the second plate 12. This split structure makes the function of each plate clearer, the processing simpler, and the assembly more flexible.

[0033] In some embodiments, the position of the second plate 12 relative to the first plate 11 is adjustable along the spacing direction between the limiting portion 22 and the limiting surface 122, and the position of the limiting plate 20 relative to the second plate 12 is adjustable.

[0034] Understandably, the position adjustment of the second plate 12 relative to the first plate 11 is achieved by changing the horizontal stacking position of the second plate 12 relative to the first plate 11, thereby changing the horizontal position of the limiting surface 122; the position adjustment of the limiting plate 20 relative to the second plate 12 is achieved by changing the horizontal stacking position of the limiting plate 20 relative to the second plate 12, thereby changing the horizontal position of the limiting part 22. Since the limiting space 500 is formed by the limiting part 22 and the limiting surface 122 being spaced apart and opposite each other in the direction of the glass 200 plate surface 210, the horizontal distance between the limiting part 22 and the limiting surface 122, i.e., the width of the limiting space 500, determines the width of the adhesive strip 300 that can pass through. When it is necessary to adapt to adhesive strips 300 of different widths, the second plate 12 can be pushed to translate relative to the first plate 11, or the limiting plate 20 can be pushed to translate relative to the second plate 12. This changes the gap width between the limiting part 22 and the limiting surface 122, thereby matching the width of the limiting space 500 with the actual width of the adhesive strip 300. Therefore, the same tooling can be used for applying adhesive strips 300 of various widths, eliminating the need for separate design and manufacturing of tooling for each width of adhesive strip 300. This provides strong versatility and reduces tooling manufacturing and management costs.

[0035] In some embodiments, such as Figure 3 , Figure 4 as well as Figure 5As shown, the first plate 11 is provided with a connecting hole 111, the second plate 12 is provided with a first waist-shaped hole 121 at the position corresponding to the connecting hole 111, and the limiting plate 20 is provided with a second waist-shaped hole 23 at the position corresponding to the connecting hole 111. The first waist-shaped hole 121 and the second waist-shaped hole 23 both extend along the interval direction between the limiting part 22 and the limiting surface 122. The adhesive strip bonding fixture also includes a fastener, which is used to pass through the second waist-shaped hole 23, the first waist-shaped hole 121 and the connecting hole 111 in sequence to lock the limiting plate 20, the second plate 12 and the first plate 11.

[0036] The connecting hole 111 can be a threaded hole, and the fastener is correspondingly a bolt, screw, or bolt-nut assembly, used to sequentially pass through the second oblong hole 23, the first oblong hole 121, and the connecting hole 111 to lock the limiting plate 20, the second plate 12, and the first plate 11 into a whole. The first oblong hole 121 and the second oblong hole 23 are oblong holes instead of round holes because the oblong holes have a certain length in the extension direction. When the fastener is loosened, the plate can translate relative to the fastener along the extension direction of the oblong hole. The width of the oblong hole perpendicular to the extension direction is basically the same as the diameter of the fastener's shank, thus constraining the position of the plate perpendicular to the extension direction and preventing displacement. In other words, the oblong hole provides the plate with freedom in the desired direction while restricting its movement in other directions, making the adjustment process controllable.

[0037] In actual operation, when it is necessary to adjust the size of the limiting space 500 according to the width of the adhesive strip 300, first loosen the fasteners to release the locking state between the plates. If it is necessary to move the second plate 12, since the first oblong hole 121 is opened on the second plate 12, and the fastener passes through the first oblong hole 121 and the connecting hole 111 on the first plate 11, after the fastener is loosened, the second plate 12 can be translated relative to the fastener and the first plate 11 along the extension direction of the first oblong hole 121. The limiting surface 122 moves together with the second plate 12, and the gap width between the limiting part 22 and the limiting surface 122 changes. Similarly, if it is necessary to move the limiting plate 20, the second oblong hole 23 is opened on the limiting plate 20. After the fastener passes through the second oblong hole 23, the limiting plate 20 can be translated relative to the fastener along the extension direction of the second oblong hole 23, and the limiting part 22 moves together with the limiting plate 20. After adjustment, tighten the fasteners. The head or nut of the fastener presses against the limiting plate 20, and the limiting plate 20, the second plate 12 and the first plate 11 are pressed and fixed in sequence by friction, so that the three plates form a rigid whole.

[0038] This application embodiment achieves position adjustment and locking between multiple plates by simply opening a waist-shaped hole and setting a fastener. The structure is simple and the cost is low. Furthermore, the processing technology of the waist-shaped hole is mature, which is convenient for mass production. Moreover, the length of the waist-shaped hole can be flexibly designed according to actual needs, and the adjustment range is controllable.

[0039] In some embodiments, such as Figure 1 As shown, multiple connecting holes 111, first waist-shaped holes 121, and second waist-shaped holes 23 are arranged at intervals along the spacing direction between the limiting part 22 and the limiting surface 122, with each connecting hole 111, each first waist-shaped hole 121, and each second waist-shaped hole 23 corresponding to one another. Multiple connecting holes 111 are provided on the first plate 11 along this spacing direction, and a first waist-shaped hole 121 is provided on the second plate 12 corresponding to the position of each connecting hole 111. A second waist-shaped hole 23 is provided on the limiting plate 20 corresponding to the position of each connecting hole 111. A fastener is provided at each position of the connecting hole 111, the first waist-shaped hole 121, and the second waist-shaped hole 23. The fastener passes through the second waist-shaped hole 23, the first waist-shaped hole 121, and the connecting hole 111 in sequence to lock the three-layer plate.

[0040] Multiple corresponding hole groups are arranged at intervals along the spacing direction between the limiting part 22 and the limiting surface 122, so that each plate is locked by multiple fastening points. The multiple fastening points are distributed along the adjustment direction. After locking, the connection between each plate is more stable, and each plate is less likely to deflect or tilt when subjected to external force. The parallelism between the limiting part 22 and the limiting surface 122 can be better maintained, thereby improving the limiting effect.

[0041] In some embodiments, the first plate 11 has a protrusion 112 at one end edge facing the glass 200. The protrusion 112 protrudes from the surface of the first plate 11 along the thickness direction of the first plate 11. The protrusion 112 is used to block the second plate 12 to limit the movement stroke of the second plate 12 relative to the first plate 11.

[0042] A protrusion 112 is provided on the edge of the first plate 11 facing the side 220 of the glass 200, protruding upward along the thickness direction of the first plate 11, i.e., protruding towards the side where the second plate 12 is located. The protrusion 112 can be integrally formed with the first plate 11, for example, by casting, stamping, or machining to form a raised stop edge at the end edge of the first plate 11, or it can be a stop block that is separately processed and fixedly connected to the first plate 11. The protrusion height of the protrusion 112 must be sufficient to block the end of the second plate 12, so that when the second plate 12 moves towards the side 220 of the glass 200 in the adjustment direction, its end edge facing the side 220 of the glass 200 can abut against the protrusion 112, thereby preventing it from moving forward further.

[0043] During the adjustment process of the second plate 12 relative to the first plate 11 along the interval direction between the limiting portion 22 and the limiting surface 122, if the operator pushes the second plate 12 to move it towards the side 220 of the glass 200, and if the end edge of the second plate 12 abuts against the protrusion 112, it indicates that the second plate 12 has moved to its limit position in that direction, and the protrusion 112 blocks further movement of the second plate 12. This limiting effect effectively reduces the risk of the second plate 12 slipping off the first plate 11 due to excessive pushing or pulling during the adjustment process, improving the safety and reliability of the adjustment operation.

[0044] In some embodiments, the first plate 11, the second plate 12, and the limiting plate 20 are made of plastic. Using plastic for the first plate 11, the second plate 12, and the limiting plate 20 can balance the lightweight, durability, and processing economy of the tooling. Specifically, the plastic material can be rigid plastic to ensure that each plate has sufficient rigidity and strength, and is not easily bent or deformed under stress, thereby ensuring the dimensional accuracy of the limiting space 500 and the pressure application effect of the pressing surface 211.

[0045] The rigid plastic can specifically be polyoxymethylene (POM), which has excellent wear resistance, self-lubrication, and dimensional stability. Its low surface friction coefficient results in low resistance and minimal wear when sliding against the side 220 of the glass 200, maintaining guiding accuracy over a long period. Alternatively, nylon 66 can be used, which possesses good comprehensive mechanical properties and fatigue resistance. It is not easily deformed or broken when subjected to repeated push-pull and compression loads, making it suitable for tooling requiring frequent adjustment and repeated use. In other possible implementations, other rigid plastic materials such as polycarbonate, polyethylene terephthalate, or acrylonitrile-butadiene-styrene copolymer can also be used, as long as they possess sufficient rigidity and wear resistance.

[0046] In some embodiments, along the thickness direction of the glass 200, the height of the pressing surface 211 is less than the height of the contact surface between the sliding plate 10 and the limiting plate 20. The limiting plate 20 is stacked on top of the sliding plate 10, and the two are bonded to each other through the contact surface. The pressing surface 211 is located on the lower side of the extension 21 of the limiting plate 20, that is, on the side facing the plate surface 210 of the glass 200, and its height is lower than the height of the contact surface. In other words, the pressing surface 211 is closer to the plate surface 210 of the glass 200 and the upper surface of the adhesive strip 300 passing through the limiting space 500. This height design allows the pressing surface 211 to form effective contact with the upper surface of the adhesive strip 300 during the tooling sliding bonding process, resulting in better pressure. The adhesive 400 between the adhesive strip 300 and the glass 200 can be fully compacted, and the bonding is more firm and reliable.

[0047] In some embodiments, the limiting portion 22 has an abutting surface 221 facing the limiting surface 122, the abutting surface 221 abutting against the adhesive strip 300, and the pressing surface 211 is connected to the abutting surface 221 at one end away from the limiting surface 122. The abutting surface 221 and the pressing surface 211 are directly connected at the junction of the limiting portion 22 and the extension portion 21, forming a continuous integral structure. Since the abutting surface 221 and the pressing surface 211 are directly connected at this junction, when the adhesive strip 300 passes through the limiting space 500, one side of its width direction contacts the abutting surface 221, and its upper surface contacts the pressing surface 211. At the same structural position, it is simultaneously subject to limiting in the width direction and downward pressure in the thickness direction, resulting in more sufficient constraint and better limiting effect. Meanwhile, the contact surface 221 and the pressing surface 211 share a structural corner. The material at this corner is continuous and the cross-section is thick, so it is not easy to deform or break under stress. The structure is stronger and can withstand repeated loads during long-term use, thus extending the service life of the tooling.

[0048] This application also proposes an automotive glass production line, which includes a rubber strip bonding fixture. The specific structure of the rubber strip bonding fixture is as described in the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0049] In summary, in the adhesive strip bonding fixture provided in this application, the sliding plate 10 slides along the edge of the glass 200 surface 210, and the limiting space 500 formed between the upper limit portion 22 of the limiting plate 20 and the limiting surface 122 of the sliding plate 10 limits the width direction of the adhesive strip 300. During the movement of the limiting plate 20 along the edge of the glass 200 surface 210, the limiting space 500 continuously constrains the adhesive strip 300, so that the adhesive strip 300 is always limited to extending along the preset bonding trajectory. At the same time, the pressing surface 211 of the extension portion 21 presses down on the adhesive strip 300 simultaneously as the adhesive strip 300 is limited and guided, continuously pressing the adhesive strip 300 onto the glass 200 surface 210. Therefore, the limiting and pressing actions are completed simultaneously during one sliding process of the tooling. This ensures that the distance between the adhesive strip 300 and the edge of the glass 200 is precisely controllable, and that the pressure on the adhesive strip 300 is consistent throughout, without any localized poor adhesion or lifting. This improves the bonding quality of the adhesive strip 300 to the glass 200 via the adhesive component 400. In addition, this application only requires two layers of plate-shaped components, the sliding plate 10 and the limiting plate 20, to be stacked. There is no need for complex drive mechanisms or linkage components. During operation, simply place the tooling on the edge of the glass 200 and push it to slide along the edge to simultaneously complete the limiting guidance and pressing of the adhesive strip 300. The operation is simple and efficient.

[0050] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
