[0048] like Figure 1 As shown, the present invention provides a pendulum component assembly device, the device including a base 10, a V-shaped seat 20, a first slider 30 and a second slider 40;

[0049] The base 10 has a first inclined plane 11 and a second inclined plane 12, wherein the first inclined plane 11 is perpendicular to and adjacent to the second inclined plane 12.

[0050] The V-shaped seat 20 is disposed on the second inclined plane 12 and in contact with the first inclined plane 11. The V-shaped seat 20 is provided with a V-shaped groove 21, and the inner sidewall 211 of the V-shaped groove 21 is provided with a sink 22 for placing the swing piece 50.

[0051] The first slider 30 is provided on one side of the swing plate 50, and the second slider 40 is provided on the other side. The first slider 30 is slidably disposed on the V-groove 21. The side of the first slider 30 facing the swing plate 50 is provided with a first positioning structure 31 for placing the first moving coil 60 so that the axis of the first moving coil 60 coincides with the axis of the swing plate 50. The first slider 30 is provided with a first heating unit for curing the adhesive between the first moving coil 60 and the swing plate 50. The second slider 40 is slidably disposed on the V-groove 21. The side of the second slider 40 facing the swing plate 50 is provided with a second positioning structure 41 for placing the second moving coil 70 so that the axis of the second moving coil 70 coincides with the axis of the swing plate 50. The second slider 40 is provided with a second heating unit for curing the adhesive between the second moving coil 70 and the swing plate 50.

[0052] Compared with the prior art, the assembly device of the present invention has the following advantages:

[0053] 1. Enables rapid online curing of pendulum components, improving production efficiency and reducing production costs;

[0054] 2. The obstruction of vision by tooling was eliminated, improving the assembly quality and consistency of the swing components;

[0055] 3. Online clamping was achieved during the curing of the adhesive in the pendulum component, ensuring consistent clamping force during adhesive curing.

[0056] According to one embodiment of the present invention, the base 10 is used for support and load bearing, and may be a rectangular structure or other shapes that facilitate the positioning of the V-shaped seat 20.

[0057] Furthermore, the base 10 can be a one-piece structure or a split structure composed of multiple side panels.

[0058] In addition, in order to facilitate the positioning of the first slider 30 and the second slider 40, so that they can only slide along the axial direction of the swing plate 50, the bottom 212 of the V-groove 21 is set as a rectangle.

[0059] Furthermore, the sliding surfaces of the first slider 30 and the second slider 40 are adapted to the shape and size of the V-groove 21, and both sliding surfaces undergo special surface treatment to achieve high wear resistance. The first slider 30 and the second slider 40 are used in pairs and are structurally similar, except that the second slider 40 is slightly longer than the first slider 30 in the length direction.

[0060] Specifically, the length of the second slider 40 is related to its material. Since the component of its weight in the direction of force application is the clamping force required for the curing of the adhesive of the pendulum component, the weight of the second slider 40 is determined according to the required clamping force, and thus the length and material of the second slider 40 are determined.

[0061] For example, the second slider 40 can be made of brass and weigh between 50g and 500g.

[0062] To facilitate the sliding of the first slider 30 and the second slider 40 on the V-groove 21, the included angle of the two inner sidewalls 211 of the V-groove 21 is set to 90°. At the same time, the first inclined plane 11 and the second inclined plane 12 can be set with a slope of 30°.

[0063] According to one embodiment of the present invention, the first positioning structure 31 includes a first cylinder 311 and a second cylinder 312 that is coaxial with the first cylinder 311. The diameter of the first cylinder 311 is larger than the diameter of the second cylinder 312. The first cylinder 311 is used to position the inner circle of the first moving coil 60 skeleton, and the second cylinder 312 is used to position the circular welding opening of the first moving coil 60 skeleton.

[0064] Specifically, the diameter of the first cylinder 311 is the same as the inner diameter of the first moving coil 60 frame, and the diameter of the second cylinder 312 is the same as the inner diameter of the circular welding opening of the first moving coil 60 frame.

[0065] Furthermore, the axis of the first cylinder 311 coincides with the axis of the first slider 30 to ensure that the axis of the first moving coil 60 coincides with the axis of the swing plate 50.

[0066] According to one embodiment of the present invention, the height of the second cylinder 312 is less than the wall thickness at the circular welding opening of the first moving coil 60 frame, so as to ensure that the first moving coil 60 frame is circumferentially positioned and does not interfere with the swing plate 50 in the axial direction.

[0067] According to one embodiment of the present invention, the second positioning structure 41 includes a third cylinder 411 and a fourth cylinder 412 that is coaxial with the third cylinder 411. The diameter of the third cylinder 411 is larger than the diameter of the fourth cylinder 412. The third cylinder 411 is used to position the inner circle of the second moving coil 70 skeleton, and the fourth cylinder 412 is used to position the circular welding opening of the second moving coil 70 skeleton.

[0068] Specifically, the diameter of the third cylinder 411 is the same as the inner diameter of the second moving coil 70 frame, and the diameter of the fourth cylinder 412 is the same as the inner diameter of the circular welding opening of the second moving coil 70 frame.

[0069] Furthermore, the axis of the third cylinder 411 coincides with the axis of the second slider 40 to ensure that the axis of the second moving coil 70 coincides with the axis of the swing plate 50.

[0070] According to one embodiment of the present invention, the height of the fourth cylinder 412 is less than the wall thickness at the circular welding opening of the second moving coil 70 frame, so as to ensure that the second moving coil 70 frame is circumferentially positioned and does not interfere with the pendulum 50 in the axial direction.

[0071] According to one embodiment of the present invention, the first slider 30 is further provided with a first temperature control unit, which is used to control the temperature of the first heating unit.

[0072] According to one embodiment of the present invention, the second slider 40 is further provided with a second temperature control unit, which is used to control the temperature of the second heating unit.

[0073] According to one embodiment of the present invention, the adhesive of the present invention is an adhesive that is easily cured by heat.

[0074] The present invention also provides a method for assembling a pendulum component, wherein the method employs the assembly device described in any of the preceding claims for assembly, and the method includes:

[0075] Install the pendulum 50 in the groove 22 of the V-shaped seat 20;

[0076] The first moving coil 60 is installed on the first positioning structure 31 of the first slider 30, adhesive is applied to the bonding position of the first moving coil 60, and the first slider 30 with the first moving coil 60 installed is placed on the V groove 21 of the V-shaped seat 20.

[0077] The second moving coil 70 is installed on the second positioning structure 41 of the second slider 40, adhesive is applied to the bonding position of the second moving coil 70, and the second slider 40 with the second moving coil 70 installed is placed on the V groove 21 of the V-shaped seat 20.

[0078] The V-shaped seat 20, which is equipped with the swing plate 50, the first slider 30 and the second slider 40, is placed on the second inclined plane 12 of the base 10. Under the gravity of the second slider 40, the first moving coil 60, the swing plate 50 and the second moving coil 70 are clamped.

[0079] The first heating unit in the first slider 30 and the second heating unit in the second slider 40 work to heat the adhesive on the first moving coil 60 and the second moving coil 70 to the required temperature, thereby achieving the bonding of the first moving coil 60, the swing piece 50, and the second moving coil 70.

[0080] Compared with the prior art, the assembly method of the present invention has the following advantages:

[0081] 1. Enables rapid online curing of pendulum components, improving production efficiency and reducing production costs;

[0082] 2. The obstruction of vision by tooling was eliminated, improving the assembly quality and consistency of the swing components;

[0083] 3. Online clamping was achieved during the curing of the adhesive in the pendulum component, ensuring consistent clamping force during adhesive curing.

[0084] After bonding the first moving coil 60, the pendulum piece 50, and the second moving coil 70, remove the V-shaped seat 20, the first slider 30, and the second slider 40 from the base 10 together. Then slide the first slider 30 and the second slider 40 away from the pendulum piece 50 to remove the bonded pendulum assembly from the V-shaped seat 20, thereby completing the pendulum assembly.

[0085] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0086] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0087] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
