Description
Technical field
The utility model is related to loudspeaker production equipment technologies, more particularly to a kind of sound film and voice coil gluing tool.
Background technology
In the production process of loudspeaker, a procedure is that the sound film that will have been produced respectively and voice coil are glued together.Sound
Structure, the outer ledge of sound film are provided with ring-shaped edge to film in the form of sheets on the whole, and round boss is provided at center, and voice coil is thickness
The cyclic structure for spending very little, when glued, needs the voice coil by thickness very little to be glued at the edge of sound center membrane round boss, therefore
It needs to ensure glued accuracy by positioning tool.
In the prior art, sound film and voice coil are respectively arranged with positioning tool, and when glued, first sound film and voice coil are respectively set
In respective positioning tool, then the gluing on sound film fastens two positioning tools, the weight using the tooling of upside is true
It protects voice coil to fit closely with sound film, realizes bonding fastness.Since the positioning tool using two different structures is respectively to sound film
It is positioned with voice coil, mold developing is to need two sets of design, both increases workload in this way, increases cost.
Utility model content
The utility model provides a kind of sound film and voice coil gluing tool, can stationary tone film and voice coil simultaneously, reduce work
Work amount and cost, and easy to use, good positioning effect.
To achieve the goals above, the utility model adopts the following technical solution：A kind of sound film and voice coil gluing tool, packet
Cylindrical body is included, the ontology is provided centrally with through-hole；
The front of the ontology is provided with cyclic annular voice coil positioning convex platform, the voice coil positioning around the inside edge of ontology
The outer diameter of boss is slightly less than the internal diameter of voice coil, and the outer ledge of ontology is provided with several sound film positioning convex platforms, several sound films
Circular array is distributed positioning convex platform on the whole, and the sound film positioning convex platform includes the first boss and second of stepped distribution
Boss, the internal diameter of the first boss are slightly larger than the outer diameter of sound film ring-shaped edge；
The reverse side of the ontology is provided with ring-type first around the inside edge of ontology and presses boss, first pressing
The width of boss cross section is more than the width of the cross section of the voice coil positioning convex platform, is less than the half of sound center membrane circular protrusions
Diameter, it is described first pressing boss on the outside of be additionally provided with ring-type second press boss, it is described second pressing boss outer diameter it is smaller
It is slightly less than the internal diameter of sound film ring-shaped edge in the internal diameter of the internal diameter of first boss, the second pressing boss.
Further, the width of first pressing boss cross section is more than the width of the cross section of the voice coil positioning convex platform
The sum of degree and voice coil thickness.
Further, the height such as the first pressing boss and the second pressing boss is arranged.
Further, the height such as the second boss and voice coil positioning convex platform is arranged.
Further, the gluing tool is integrally formed.
Sound film provided by the utility model and voice coil gluing tool, can stationary tone film and voice coil simultaneously, reduce work
Amount and cost, and easy to use, good positioning effect.

Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only explaining this
Utility model is not used to limit the utility model.
The sound film of the utility model and voice coil gluing tool, including cylindrical body 1, the ontology 1 are provided centrally with
Through-hole 2；As shown in Figure 1, the front of the ontology 1, cyclic annular voice coil positioning convex platform 3, institute are provided with around the inside edge of ontology 1
The outer diameter for stating voice coil positioning convex platform 3 is slightly less than the internal diameter of voice coil, and the outer ledge of ontology 1 is provided with several sound film convexes
Platform 4, circular array is distributed several sound film positioning convex platforms 4 on the whole, and the sound film positioning convex platform 4 includes stepped distribution
First boss 41 and second boss 42, the internal diameter of the first boss 41 be slightly larger than the outer diameter of sound film ring-shaped edge, described the
Two boss 42 are highly arranged with voice coil positioning convex platform 3 equal.
The reverse side of the ontology 1 is provided with ring-type first around the inside edge of ontology 1 and presses boss 5, and described first presses
The width of 5 cross section of belling platform is more than the sum of width and voice coil thickness of the cross section of the voice coil positioning convex platform 3, is less than sound film
The radius of central circular protrusion, it is described first pressing boss 5 outside be additionally provided with ring-type second press boss 6, described second
The outer diameter of pressing boss 6 is slightly less than the internal diameter of first boss 41, and the internal diameter of the second pressing boss 6 is slightly less than sound film ring-type side
The internal diameter of edge, the first pressing boss 5 and second press the height such as boss 6 and are arranged.
In use, two gluing tools match, voice coil is first sleeved on to the outside of voice coil positioning convex platform 3, then in sound
Sound film, is then placed on the inside of first boss 41 by gluing on the round boss of film, and in second boss 42, sound film is just at this time
The marginal position of the round boss of sound film can be accurately fixed on.Next the reverse side of another gluing tool is placed on sound
On film, at this point, the ring-shaped edge of the second pressing 6 stationary tone film of boss, and first presses boss 5 due to gravity, just
Sound film is pressed together with voice coil, completes glued work.The gluing tool of shape above-mentioned in this way can be accurate by sound film and voice coil
It is really glued, it is time saving and energy saving, it is cost-effective.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these modifications and variations should all belong to the protection domain of the appended claims for the utility model.
