Abstract

This utility model discloses a positioning fixture for preventing the rotation of an irregularly shaped paper basin, including a base and an adjusting seat. The upper wall of the base has a contoured surface with a negative pressure hole penetrating the base wall. The negative pressure hole is used to adsorb the paper basin placed on the contoured surface. The adjusting seat is slidably installed on the upper wall of the base. The middle of the adjusting seat has an installation through hole for placing a support. The lower part of the support passes through the installation through hole and is positioned opposite to the upper wall of the paper basin. An elastic mechanism is provided between the base and the adjusting seat. The pressing mechanism applies a downward pressing force to the adjusting seat and the support, and after the paper basin and the support are engaged, they are pressed together, thereby achieving elastic engagement, effectively preventing deformation of the paper basin, and ensuring mutual fixation between the support and the paper basin, thus preventing the paper basin from rotating.

Description

Technical Field

[0001] This utility model relates to the field of loudspeaker manufacturing equipment, and in particular to a non-rotating positioning fixture for irregularly shaped paper cones. Background Technology

[0002] In a loudspeaker, there is a large bonding area between the cone and the bracket. Therefore, when using existing fixtures, rotation often occurs during the bonding process of the cone and the bracket, which affects the bonding accuracy and reduces the relative structural stability.

[0003] At the same time, because the bonding area is large, direct pasting by a robotic arm will also cause problems. Therefore, how to achieve automated processing while ensuring processing accuracy is the key to the design. Utility Model Content

[0004] The main purpose of this utility model is to propose a non-rotating positioning fixture for irregularly shaped paper basins. The aim is to design a fixture that achieves the fit and fixation between the paper basin and the support, and at the same time, the anti-rotation structure and the adjustment seat achieve the fit and fixation between the paper basin and the support.

[0005] To achieve the above objectives, this utility model proposes an anti-rotation positioning fixture for irregularly shaped paper basins, comprising:

[0006] The base has a contoured surface on its upper wall, and the contoured surface has a negative pressure hole that penetrates the base wall. The negative pressure hole is used to absorb the paper basin placed on the contoured surface.

[0007] An adjustable base is slidably mounted on the upper wall of the base. The adjustable base has a mounting hole in its center. The adjustable base is used to place a bracket, and the lower part of the bracket passes through the mounting hole and is positioned opposite the upper wall of the paper tray.

[0008] An elastic mechanism is provided between the base and the adjustment seat.

[0009] In actual automated assembly, the first robotic arm clamps the paper tray onto the contoured surface of the base, then uses negative pressure holes to absorb it. The second robotic arm then holds the support bracket and places it on the adjustment seat.

[0010] At this time, there is a predetermined gap between the upper wall of the paper basin and the support and the lower wall of the paper basin that needs to be attached (which is compatible with the stroke length of the elastic mechanism (preferably less than the predetermined gap)).

[0011] The areas of the paper basin that need to be bonded are coated with glue or have an adhesive layer.

[0012] Finally, the pressing mechanism applies a downward pressing force to the adjusting seat and the support, and after the paper basin and the support are locked together, they are attached together, thus achieving elastic locking, effectively preventing deformation of the paper basin, and also ensuring mutual fixation between the support and the paper basin, preventing the paper basin from rotating.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0029] like Figures 1 to 5 As shown, a non-rotating positioning fixture for an irregularly shaped paper basin includes:

[0030] The base 11 has a contoured surface 3 on its upper wall. The contoured surface 3 has a negative pressure hole 4 that penetrates the wall of the base 11. The negative pressure hole 4 is used to adsorb the paper basin placed on the contoured surface 3.

[0031] An adjusting base 12 is slidably mounted on the upper wall of the base 11. The adjusting base 12 has a mounting hole 5 in its center. The adjusting base 12 is used to place a support, and the lower part of the support passes through the mounting hole 5 and is positioned opposite the upper wall of the paper tray.

[0032] An elastic mechanism 2 is provided between the base 11 and the adjusting seat 12.

[0033] During actual automated assembly, the first robotic arm clamps the paper tray onto the contour surface 3 of the base 11, and then adsorbs it through the negative pressure hole 4. Then, the second robotic arm holds the bracket and places it on the adjustment seat 12.

[0034] At this time, there is a predetermined gap between the upper wall of the paper basin and the support and the lower wall of the paper basin that needs to be attached, which is suitable for the stroke length of the elastic mechanism 2 (preferably less than the predetermined gap).

[0035] The areas of the paper basin that need to be bonded are coated with glue or have an adhesive layer.

[0036] Finally, the pressing mechanism applies a downward pressing force to the adjusting seat 12 and the bracket, and after the paper basin and the bracket are locked together, they are attached together, thereby achieving elastic locking, effectively avoiding deformation of the paper basin, and also ensuring mutual fixation between the bracket and the paper basin, preventing the paper basin from rotating.

[0037] Specifically, the central part of the contour surface 3 is provided with a convex surface 31.

[0038] In this embodiment of the utility model, the convex surface 31 is provided with a plurality of protrusions distributed circumferentially around the axis, thereby realizing the limiting of the paper basin. Of course, when the shape of the paper basin is unique, the negative pressure hole 4 may not be used.

[0039] Specifically, the negative pressure hole 4 is connected to the vacuum device.

[0040] In this embodiment of the invention, the outer side of the base 11 is provided with a plurality of linear bearing sleeves distributed circumferentially around the axis.

[0041] The adjusting seat 12 is provided with a guide shaft 72 that cooperates with the linear bearing sleeve 71, which ensures the vertical movement accuracy between the base 11 and the adjusting seat 12.

[0042] Specifically, the upper wall of the base is provided with multiple top springs (i.e., the elastic mechanism 2). The upper end of the top spring abuts against the adjustment hole of the adjustment seat 12 and can move to a position extending out of the upper wall of the adjustment seat 12. The top spring is used to apply an upward elastic force to the adjustment seat 12, so that there is a predetermined gap between the paper tray and the support for the pressing device to apply a predetermined pressure.

[0043] In this embodiment of the invention, the inner diameter of the mounting hole 5 is larger than the outer diameter of the paper basin, so that the paper basin and the bracket can be removed at the same time after they are installed together.

[0044] Specifically, the upper wall of the adjusting seat 12 is provided with a plurality of spaced limiting blocks 61 on the periphery of the mounting hole 5, and a limiting groove 62 is provided between adjacent limiting blocks 61, wherein the limiting groove 62 is used to limit the structure of the bracket.

[0045] In this embodiment of the utility model, the inner side of the upper end of the limiting block 61 is provided with a guide slope 63, which not only serves as a guide but also reduces scratches on the product.

[0046] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using 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.
