Description
The present invention relates to structure and its assembly method of miniaturized flat brushless motor.
Current, people expect a kind of have littler, lighter, thinner, the more feeling of high class and the portable information equipment that for example comprises mobile phone (to call equipment in the following text) that can use for more time.The equipment producer is pouring into all effort for meeting these hopes, desiring to make the inner electronic component of packing into is low power consumption, wiring substrate is a multiple stratification, gather electronic component and the high equipment of productivity ratio to high-density thereby make, and use housing to make the equipment of not only thin but also feeling of high class as the light metal of magnesium etc.For the flat brushless motor that is used as the equipment drive source same requirement is arranged also.
In mobile phone, the vibration generation function that silent call is used is absolutely necessary at present.The conventional method that function takes place for this vibration is to realize with the vibrating motor of being with eccentrically mounted weight, has the characteristic of small-sized, low power consumption, this excellence of low price, helps the miniaturization and of equipment.And this vibrating motor can also seek to bear a part of task of the value that improves equipment.
When for the value that improves equipment to flat brushless motor (back as vibrating motor or equipment drive source, sometimes both unifications are called brushless motor or motor simply) when desired necessary condition is taken into full account, at first, the also essential aggregation degree that is fit to improve equipment of brushless motor.To this, hope can utilize surface mounting technology (Surface Mount Technology) and itself and other solid electronic element similarly is installed on the substrate of equipment.When on substrate, offering the hole and passing terminal, just cause the aggregation degree on the multilager base plate to descend.In addition, be to improve aggregation degree, wish to have with in abutting connection with the electronic component of configuration near and can dispose the form of installation to high-density.
The second, for improving the productivity ratio of equipment, the essential suitable installation procedure identical of brushless motor with other solid electronic elements.Therefore, wish to have form and the thermal endurance that is suitable for anti-stream (リ Off mouth-) soldering construction method.In addition, wish that also having the available assembly machine identical with other solid electronic elements carries out the form that high efficiency is installed.
The 3rd, brushless motor also must be suitable for housing miniaturization, the lightweight of equipment.Therefore, wish to have higher resistance to impact.
Now describe with regard to the background that constitutes this resistance to impact requirement.Yes is used for guaranteeing that equipment falls the requirement that also can not destroy even resistance to impact requires.At present, generally be to guarantee to a certain degree spacious and comfortable in equipment inside, elastomer is packed in the equipment.But, in recent years, small-sized, slimming requirement that elastomeric space can not be guaranteed.According to above-mentioned expectation, desire to be surface mounted on the substrate identical with other electronic components, then since on substrate direct fixing brushless motor, absorb impact so can not resemble the elastic support structure.
In addition, exist becoming flexible with light metals such as magnesium or aluminium formation equipment housing as mentioned above.Though these weight metals are light, rigidity is far above resin, and resiliency is inferior.Therefore, act on unexistent in the past bigger impulsive force on the substrate of housing being fixed on, be directly passed to the motor that is fixed on the substrate.Its result for motor and its joint portion, seek great resistance to impact.According to these situations, though the required value in the past of the resistance to impact of motor is 3000～5000G, it is 10000～20000G that the result requires.
And this motor is only the scolder on the substrate to be given heat fused (anti-stream), offers the hole and do not make scolder pass through ground (mounted on surface) to carry out soldering and connect, wish to satisfy this resistance to impact on substrate.Even it is only anti-also very difficult in anti-stream heating-up temperature (about 250 ℃).Though the present inventor has sought to satisfy the prior art of these all requirements.But fail to find it.Therefore, various repeatedly researchs and finished the present invention.Because motor of the present invention is the platypelloid type of height less than banner, so be also referred to as flat vibrating motor or flat brushless motor sometimes.
Below, focus on existing assembly method narration brushless motor.
Small-sized and flat brushless motor generally adopts the structure of assembling each part on the base that is made of metal.Because motor is the rotating power source of equipment, thus need with sufficient rigidity be installed on the equipment, metab precision height and be suitable as the reference for assembling etc. of motor.During assembling motor, base is placed on the saddle (positioning operation platform), each part is installed on base again.
Under the situation of this assembly method, when putting base on saddle, about the affirmation base, aligning direction puts thereby position.But along with motor diminishes, this operation required time also has the tendency that thereupon prolongs.In case part is less, loading and unloading and operation just become difficult.This tendency is not limited to the base of motor, also is same when assembling electronic component on printed base plate.On less printed base plate, be difficult to install expeditiously electronic component.
And being used for the motor of portable equipment, miniaturization and light-weighted requirement are all very tight.But because can not sacrifice the characteristic of motor when making the motor miniaturization and, so rotor and stator naturally and understandably need certain size and weight.Therefore, produced in addition, be the problem that the shared volume and weight of surrounding member at center is reduced to connecting structure for electrical equipment with the structure that keeps rotor and stator, stator and outside.
Yet, a kind of employed usually when making the built-in circuit of various equipment, printed base plate assembly method of being called " multi-joint substrate " was arranged in the past.It is following assembly method: when the profile of printed base plate when being less or special-shaped, arrange them a plurality of and with passing a bridge or framework connects between them, thereby make usefulness electronic part mounting easy-on shape.And, electronic component is installed thereon after, gap bridge is cut, take out the printed base plate assembly, finish assembling.
But in this way, unaccommodated place is arranged also when further seeking miniaturization.At first, when printed base plate becomes hour, pass a bridge or the shared area of framework increases relatively, stock utilization descends.In addition, even expectation with more miniaturization of printed base plate, when cutting off with cutter when passing a bridge, also need be avoided its blade to run into printed base plate and avoids cutting off the stress that is brought, so can not dispose element near cutting off partly.Though also gap bridge is fractureed sometimes or cut off, separated portions becomes thicker cutting plane, thereby the outward appearance of making and dimensional accuracy worsen.Because these shortcomings, so be unaccommodated to miniaturized component.In addition, owing to after assembling is finished, separate, therefore, exist the anxiety that makes end product quality decline because of the impact that brings along with cutting off.
Therefore, constitute under the situation of compact motor, expect a kind of assembly method that addresses these problems desiring to high-density element to be installed on the printed base plate.
For satisfying these expectations, it also is a problem that the structure that keeps rotor, stator, stator and connecting structure for electrical equipment, these members of outside shared volume, weight are reduced.
The objective of the invention is to satisfy aforesaid various requirement, promptly the 1st purpose is the aggregation degree that helps to improve equipment.For this reason, problem be should utilize the SMT technology on the substrate of equipment, install, have with the electronic component of adjacency near and can dispose the form of installation to high-density.
The 2nd purpose is the productivity ratio that helps to improve equipment.For this reason, problem is to have to be suitable for the anti-form that flows the soldering construction method with thermal endurance and have the form that can install expeditiously with identical assembly machine.
The 3rd purpose is the miniaturization and that helps equipment.For this reason, problem is to have enough resistances to impact.
The 4th purpose is further to improve the Assembling Production rate.For this reason, problem is how to make not only to operate easily but also easily-assembled structure and assembly method.
Comprehensive purpose is exactly to realize the portable information equipment aforesaid, that a kind of high added value is provided with more small-sized light weight, high production rate.

So, the motor of present embodiment disposes a plurality of terminals (lug 2a, 2e) and with insulation division they is separated at bottom surface side.As long as just can carry out the terminal structure that soldering connects owing to make to put to heat on the equipment substrate, so can be suitable for the SMT mounting means, available anti-stream construction method is carried out soldering.Here, as shown in Figure 1, when the terminal of bottom surface sections not from base surface area when side is outstanding, can be not only narrow and small but also to high-density to install with the interval of the electronic component of adjacency.And the hole that terminal is protruded from the bottom surface more vertically with the substrate of equipment fastens, and when giving soldering herein, just can obtain firm bed knife.But preferably basically as long as carrying out face with the surface of the substrate of equipment just contacts and can obtain enough confining forces, therefore, the present invention is to attach most importance to according to this requirement concerning equipment.
In addition, in the motor of present embodiment, has the terminal (lug 2e) that does not participate in being electrically connected at bottom surface side.Shown in Fig. 1 c, be formed with 8 lug 2a, 2e in the bottom surface, and that wherein participate in being electrically connected is 4 (lug 2a).Owing to have many lugs, so can increase the substrate of equipment and the bonded area of motor, combination securely.Therefore, can improve resistance to impact when equipment is fallen.
In addition, in the motor of present embodiment, be in a plurality of lug 2a, the 2e of bottom surface, also be configured in any side by the line of bottom surface center of fiqure.Furtherly, be configured to point symmetry.Many situations are that the center of fiqure of bottom surface is roughly consistent with the position of centre of gravity of motor, and by terminal arrangement is become symmetry, can make the composite force of the confining force that keeps each terminal consistent with position of centre of gravity.That is, impulsive force each terminal can be distributed to equably, the resistance to impact when equipment is fallen can be brought into play to greatest extent.So, utilize the soldered joint structure between the substrate of the bottom surface of motor and equipment and the technology of supporting motor securely is first point that improves resistance to impact.
In addition, the roughly whole of the motor of present embodiment surrounded by shell.Therefore, can protect inside, prevent that the counter hot blast, the infrared ray that produce because of the soldering fusing of flowing in the operation from entering, thereby can prevent to improve thermal endurance, become and be suitable for the anti-structure that flows brazing mode because of heating damages inner electric motor structure.Because the bottom surface is printed base plate, so thermal endurance, thermal insulation are well light and handy again.In addition, owing to become easy-operating shape by being provided with shell, so can be installed in expeditiously on the substrate of equipment.Owing to also can prevent that dust from entering,, can keep the reliability of motor so can prevent the motor brake that dust causes.
The rotor body of brushless external rotor formula motor has the function of cover.Do not have the brush collector machine that must be protected, stator and bearing arrangement are covered by rotor.Therefore, there was not in the past the specially cover of setting.The present invention has createed a kind of profile and cover are given many functions and be suitable for SMT installation method and the brushless motor of anti-stream brazing mode.
In addition, the motor of present embodiment has stator core 6 and winding 7 wound thereon.Rotor 4 rotatably surround stator 1 around.Promptly adopt band outer-rotor structure unshakable in one's determination.The magnetic conductance of the magnetic circuit of this structure is than aircored structure height, thereby available littler magnet obtains identical output.Therefore, can make rotor become light weight, can alleviate the load of bearing arrangement and improve resistance to impact.The lightweight of rotor is second point that resistance to impact is improved.By the way, to same external diameter and roughly the relative coreless type in plane, the band external-rotor-type unshakable in one's determination of same characteristic compare, the result be this magnet weight the former be 1.05gw, the latter is 0.37gw.So, band external-rotor-type unshakable in one's determination can become lighter rotor weight.For example, if light 0.5gw, then the load on the bearing arrangement can alleviate 10kgf under the environment of 20000G.Because the bearing arrangement of this motor is very little, has bigger meaning so alleviate the 10kgf load.
In addition, band outer-rotor structure unshakable in one's determination is flat short.Be that center of gravity is in lower position.So when when the direction parallel with the substrate of equipment applies impulsive force, the moment that peels direction that is applied on the terminal connecting portion diminishes.Therefore, compare with the high shape of equal in quality and improved resistance to impact
In addition, because the motor of present embodiment does not have the brush collector machine,, easily make flat short shape so do not need its axial space.Therefore, according to above-mentioned same reason, compare with the high shape of equal in quality and to have improved resistance to impact.The certain also distortion of brushless collector machine or the anxiety of damage.Therefore, can make inner structure produce firm, simple effect, improve the resistance to impact of motor.In addition, having no way of makes the anxiety of the function reduction of rectification mechanism in soldering or solder flux etc., becomes to be suitable for the anti-structure that flows brazing mode.
Many technology such as the rotor of the technology of supporting motor, light weight, short shape, the shell (cover and printed base plate) of light weight, simple structure are concentrated and are obtained higher resistance to impact so, the soldered joint structure between the substrate of bottom surface that utilizes motor and equipment and securely.
