[0001] This utility model relates to the field of knob assembly technology, and in particular to a knob assembly fixture. Background Technology
[0002] Knob assemblies, as an important component of the user interface, are widely used in electronic devices, home appliances, automotive dashboards, and other fields. Traditional knob assemblies typically consist of a knob body and a decorative cover plate covering its surface. The cover plate often features markings, scales, or a decorative layer to enhance the product's aesthetics and functionality. The traditional assembly process involves fixing the knob body in place and then manually attaching the adhesive-backed cover plate to the knob body. During the pressing process, operators are highly susceptible to misalignment or uneven force, leading to misalignment of the cover plate and affecting the consistency of the product's appearance. Utility Model Content
[0003] The main purpose of this utility model is to provide a knob assembly fixture, which aims to reduce misalignment during the assembly process of knob components.
[0004] To achieve the above objectives, this utility model provides a knob assembly fixture for assembling a knob body and a knob cover plate. The knob assembly fixture includes:
[0005] Workbench;
[0006] A cover plate fixing structure is provided on the workbench to position the knob cover plate;
[0007] A guide structure is provided on the worktable and located on one side of the cover plate fixing structure; and
[0008] A knob mounting plate is movably disposed above the cover plate fixing structure and is used to mount the knob body. The knob mounting plate and the guide structure are slidably connected to move closer to or further away from the worktable.
[0009] In one embodiment, the guide structure includes guide rods, at least two of which are spaced apart, and the guide rods are slidably connected to the knob mounting plate.
[0010] In one embodiment, two guide rods are arranged side by side, and the two guide rods are located on the same side of the knob mounting plate. The guide rods and the side of the knob mounting plate are in sliding contact.
[0011] In one embodiment, the cover plate fixing structure includes a positioning groove, the opening of which is expanded outward to form a chamfer.
[0012] In one embodiment, the guide rod extends through the knob mounting plate.
[0013] In one embodiment, the knob assembly fixture further includes a knob positioning structure that connects the knob mounting plate and the knob body.
[0014] In one embodiment, the knob positioning structure includes a positioning pin and a positioning hole that cooperates with the positioning pin. One of the knob mounting plate and the knob body is provided with the positioning pin, and the other of the knob mounting plate and the knob body is provided with the positioning hole.
[0015] In one embodiment, the knob assembly fixture further includes a knob fixing structure, through which the knob body and the knob mounting plate are detachably connected.
[0016] In one embodiment, the knob fixing structure is configured as a magnetic structure.
[0017] In one embodiment, the cover plate fixing structure includes a negative pressure air intake port disposed on the workbench and an air intake pipe communicating with the negative pressure air intake port; and / or, the cover plate fixing structure includes positioning rods, and at least three positioning rods are provided at circumferential intervals along the knob cover plate.
[0018] The technical solution of this application, through the set cover plate fixing structure, can stably position the knob cover plate. After fixing the knob cover plate to the worktable using the cover plate fixing structure, with the adhesive side of the knob cover plate facing upwards, the adhesive backing is then peeled off. The knob body is fixed to the knob mounting plate. Through the set guide structure, the knob mounting plate can slide along a preset path, achieving accurate alignment between the knob body and the knob cover plate, effectively reducing the misalignment problem that is prone to occur in traditional manual pasting processes. It can be understood that by setting the cover plate fixing structure to stably position the knob cover plate, and using the guide structure to limit the movement of the knob mounting plate, the knob body can be pressed vertically downwards along a predetermined path, achieving alignment with the knob cover plate. This overcomes the circumferential, radial, or tilting offset problems caused by manual operation deviations in traditional processes, improves the bonding effect between the knob cover plate and the knob body, and thus improves the quality and appearance consistency of the product. In addition, fixing the knob cover plate in place, compared to fixing the knob body in place, can prevent the adhesive on the knob cover plate from sticking to other components during the bonding process, reduce the adverse effects on the adhesive on the knob cover plate, and improve the reliability of the bonding between the knob cover plate and the knob body.

[0031] Traditional assembly involves fixing the knob body in place and then manually attaching an adhesive-backed cover plate to it. During the pressing process, operators are prone to misalignment or uneven force, causing the cover plate to shift during attachment, affecting the consistency of the product's appearance. Furthermore, when manually attaching the adhesive-backed cover plate to the knob body, the adhesive can easily come into contact with other components, negatively impacting its adhesion and affecting the reliability of the bond between the cover plate and the knob body.
[0032] In view of this, this utility model embodiment provides a knob assembly fixture. By setting a cover plate fixing structure to stably position the knob cover plate, and using a guide structure to limit the movement of the knob mounting plate, the knob body can be pressed vertically downwards along a predetermined path, achieving alignment with the knob cover plate. This overcomes the circumferential, radial, or tilting offset problems caused by manual operation deviations in traditional processes, improves the bonding effect between the knob cover plate and the knob body, and thus enhances the product's quality and appearance consistency. Furthermore...
[0033] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.
[0034] like Figures 1 to 3 As shown in the figure, this utility model embodiment proposes a knob assembly fixture for assembling a knob body and a knob cover plate. The knob assembly fixture includes:
[0035] The workbench 100 can adopt existing common structures and is not limited here. The material of the workbench 100 can be plastic or metal, and the shape can be square or round, whichever is more suitable according to the actual application. Typically, the workbench 100 has a plate-like structure and is supported on the ground by at least three support legs to maintain the stability of the workbench 100 surface;
[0036] A cover plate fixing structure 200 is provided on the workbench 100 to position the knob cover plate. The cover plate fixing structure 200 can be a recessed groove provided on the surface of the workbench 100, or it can be multiple limiting rods provided on the surface of the workbench 100. The multiple limiting rods are at least three and form a limiting space. The center of the limiting space corresponds to the center of the knob cover plate and also corresponds to the center of the knob body on the knob mounting plate 400, thereby achieving accurate alignment of the knob cover plate and the knob body during bonding.
[0037] A guide structure 300 is disposed on the worktable 100 and located on one side of the cover plate fixing structure 200. It is understood that the guide structure 300 can guide the movement of the knob mounting plate 400. The guide structure 300 can be a guide rail or a guide rod, which is not limited here; and
[0038] A knob mounting plate 400 is movably disposed above the cover plate fixing structure 200 and is used to mount the knob body. The knob mounting plate 400 and the guide structure 300 are slidably connected to move closer to or further away from the worktable 100. It can be understood that the knob mounting plate 400 is used to fix the knob body. After the knob body is fixed to the knob mounting plate 400, pressing down the knob mounting plate 400 will adhere the knob body to the knob cover plate.
[0039] In this embodiment, the cover plate fixing structure 200 securely positions the knob cover plate. After fixing the knob cover plate to the workbench 100 with the adhesive side facing upwards, the adhesive backing is peeled off. The knob body is fixed to the knob mounting plate 400. The guide structure 300 allows the knob mounting plate 400 to slide along a preset path, achieving accurate alignment between the knob body and the knob cover plate. This effectively reduces the misalignment problem that easily occurs in traditional manual pasting processes. It can be understood that by using the cover plate fixing structure 200 to stably position the knob cover plate and the guide structure 300 to limit the movement of the knob mounting plate 400, the knob body can be pressed vertically downwards along a predetermined path, achieving alignment with the knob cover plate. This overcomes the circumferential, radial, or tilting offset problems caused by manual operation deviations in traditional processes, improving the bonding effect between the knob cover plate and the knob body, thereby enhancing the product's quality and appearance consistency. In addition, fixing the knob cover plate in place, compared to fixing the knob body in place, can prevent the adhesive on the knob cover plate from sticking to other components during the bonding process, reduce the adverse effects on the adhesive on the knob cover plate, and improve the reliability of the bonding between the knob cover plate and the knob body.
[0040] In one embodiment, the guide structure 300 includes guide rods, and the guide plate can be a cylinder or a cuboid. One end of the guide rod is fixed to the worktable 100, and the other end extends away from the worktable 100. At least two guide rods are spaced apart, and the guide rods are slidably connected to the knob mounting plate 400. The guide rods restrict the downward sliding path of the knob mounting plate 400, improving the alignment accuracy of the knob body and the knob cover, thereby preventing misalignment and improving the bonding effect. In this embodiment, the guide rods provide a simple structure, effectively reducing usage costs and facilitating later maintenance. Of course, three or more guide rods can also be provided, collectively forming a fixed space for positioning the knob mounting plate 400.
[0041] In one embodiment, two guide rods are arranged side by side, both located on the same side of the knob mounting plate 400, and the guide rods slide in contact with the side of the knob mounting plate 400. Since the knob body has a short stroke during descent, only one side of the knob mounting plate 400 needs to be positioned, and alignment of the knob body and knob cover can be achieved during assembly. Specifically, two guide rods are provided, which can abut against either the long or short side of the knob mounting plate 400. When the knob mounting plate 400 is pressed down, the two guide rods are limited on the same side of the knob mounting plate 400. In this embodiment, the knob mounting plate 400 and the guide rods are separate; the guide rods are pressed down only when the knob mounting plate 400 is pressed down, and the two guide rods limit the movement of the knob mounting plate 400. Understandably, the process involves first manually placing the knob mounting plate 400 against the guide rods, then manually adjusting the position of the knob mounting plate 400 along the arrangement of the two guide rods to align the knob body on the mounting plate 400 with the knob cover. Maintaining the arrangement of the knob mounting plate 400 along the two guide rods, pressing down on the knob mounting plate 400 ensures that the knob body and knob cover remain essentially aligned due to the limiting effect of the two guide rods, thus bonding the knob body to the knob cover. Furthermore, separating the knob mounting plate 400 from the guide rods makes it easier to fix the knob body, and the pressing process is simpler and more convenient.
[0042] In one embodiment, the cover plate fixing structure 200 includes a positioning groove, in which the knob cover plate is disposed. The shape of the positioning groove is adapted to the shape of the knob cover plate to achieve positioning and fixing of the knob cover plate. The groove opening of the positioning groove expands outward to form a chamfer. It can be understood that the chamfer formed by the expansion of the groove opening of the positioning groove can correct the deviation of the knob body entering the positioning groove, further improving the alignment accuracy of the knob body and the knob cover plate, thereby reducing misalignment and improving the bonding effect. That is, the knob mounting plate 400 is first pressed down along the guide rod until the knob body contacts the chamfer. As the knob mounting plate 400 continues to be pressed down, the knob body moves along the chamfer to correct the deviation, so that the knob body and the knob cover plate are aligned and bonded.
[0043] In one embodiment, the guide rod passes through the knob mounting plate 400. In this embodiment, the guide rod passes through the knob mounting plate 400, meaning the knob mounting plate 400 can move along the axial direction of the guide rod to achieve downward pressure. In one embodiment, two guide rods are provided, spaced apart, either diagonally or side-by-side along the long or short side of the knob mounting plate 400. By guiding the knob mounting plate 400 through the guide rod, the knob mounting plate 400 is guided, ensuring that the knob body on the knob mounting plate 400 and the knob cover plate on the worktable 100 remain aligned during downward pressure, effectively preventing misalignment and improving the bonding effect.
[0044] In one embodiment, the knob assembly fixture further includes a knob positioning structure 500, connecting the knob mounting plate 400 and the knob body. It is understood that the knob positioning structure 500 can fix the knob body in place, ensuring it is fixed at a predetermined position on the knob mounting plate 400. This facilitates alignment between the knob body and the knob cover, prevents displacement of the knob body on the knob mounting plate 400, and reduces misalignment between the knob body and the knob cover during bonding.
[0045] In one embodiment, the knob positioning structure 500 includes a positioning pin 510 and a positioning hole that mates with the positioning pin 510. One of the knob mounting plate 400 and the knob body is provided with the positioning pin 510, and the other of the knob mounting plate 400 and the knob body is provided with the positioning hole. Specifically, the knob positioning structure 500 includes a positioning pin 510 and a positioning hole. Through the cooperation of the positioning pin 510 and the positioning hole, the installation and positioning of the knob body can be easily and conveniently achieved. In one embodiment, the positioning pin 510 can be provided on the knob mounting plate 400, while a positioning hole is provided on the knob body. The positioning hole can utilize the existing holes on the knob body, further simplifying the structure. Of course, in other embodiments, the positioning pin 510 can be provided on the knob body, while a positioning hole is provided on the knob mounting plate 400. In practical applications, the preferred method can be selected according to the specific situation, and no limitation is made here.
[0046] In one embodiment, the knob assembly fixture further includes a knob fixing structure, through which the knob body and the knob mounting plate 400 are detachably connected. Thus, the knob fixing structure secures the knob body to the knob mounting plate 400, preventing the knob body from separating from the knob mounting plate 400 during downward pressing. The knob fixing structure can be a snap-fit structure or other existing structures capable of detachment; no limitation is made here.
[0047] Optionally, the knob fixing structure is configured as a magnetic structure, meaning the knob body is fixed to the knob mounting plate 400 by magnetic attraction, which is convenient to operate. In one embodiment, the knob fixing structure includes a first magnet and a second magnet with opposite magnetic properties. The first magnet is disposed on the knob mounting plate 400, and the second magnet is disposed on the knob body. Specifically, the knob mounting plate 400 and the knob body are magnetically fixed by the cooperation of the first magnet and the second magnet, which is simple and convenient and reduces damage to the knob body. Of course, the knob body is usually a metal part, and the first magnet can also be directly disposed on the knob mounting plate 400, allowing the knob body to be directly attracted by the first magnet, further simplifying the structure.
[0048] In one embodiment, the cover plate fixing structure 200 includes a negative pressure air intake port disposed on the workbench 100 and an air intake pipe 600 communicating with the negative pressure air intake port. Thus, by means of negative pressure air intake, the knob cover plate is fixed on the workbench 100 to prevent the knob cover plate from shifting. And / or, the cover plate fixing structure 200 includes positioning rods, and at least three positioning rods are provided at intervals along the circumference of the knob cover plate. Thus, at least three positioning rods form a positioning space and abut against at least three different positions of the knob cover plate, effectively fixing the knob cover plate.
[0049] 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 embodiments. Any equivalent structural transformations made under the technical concept of the present utility model using the description and drawings of the present utility model embodiments, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model embodiments.
