A kind of magnetic steel mounting device of speaker, including an installation table top, fixing cylinder base and magnet steel delivery device it is provided with abreast on described installation table top, fixing cylinder base upper end is bolted with the vertical sleeve that magnetizes, magnet steel delivery device includes a transversely movable push rod and the power source driving push rod to move forward and backward, push rod has the final position after an original position and reach, the side that fixing cylinder base is corresponding with push rod is provided with the push-rod hole suitable with push rod, the opposite side of fixing cylinder base is provided with the magnet steel outlet relative with push-rod hole, magnetize sleeve and push rod is made by nonferromagnetic material.
Magnetize and can place pole orientation in sleeve and the most mutually adsorb the magnet steel of bunchiness, power source can be cylinder or motor combines drive mechanism, thus automatically moving of push rod can be conveniently realized, to be released one by one from the magnet steel exit of fixing cylinder base by the magnet steel of bunchiness, single magnet steel can be installed in the magnetic bowl of speaker skeleton by operator easily.
As preferably, described fixing cylinder base is provided with the magnet steel mounting table that nonferromagnetic material is made in the downside that magnet steel exports, there is on the upside of the end of push rod a rectangular indentation, so that push rod end is two grades step-like, the height of magnet steel outlet is more than the height of a magnet steel and the height sum of push rod end first order step and less than the height of two magnet steel.
So, when pushrod advances, the magnet steel of bottom is first released magnet steel and is exported and rest on magnet steel mounting table by its less end, now the magnet steel in magnet steel sleeve automatically falls and is pressed on the first order step surface of push rod end, under the promotion of the second level step of push rod end, the magnet steel being pressed on the first order step surface of push rod end is pushed out magnet steel and exports and remain on the first order step surface of push rod end, thus can release two magnet steel during the one-off of push rod simultaneously and be separated.Owing to the height of magnet steel outlet is less than the height of two magnet steel, therefore, during the push rod first magnet steel bottom pushing, laminate superincumbent second magnet steel and stopped without being released simultaneously by magnet steel outlet.When starting to push second magnet steel, owing to the height of magnet steel outlet is greater than the height of a magnet steel and the height sum of push rod end first order step, it is thus ensured that it is successfully sent from magnet steel exit.
nullAs preferably，There is on the upside of the end of described push rod a rectangular indentation，So that push rod end is two grades step-like，When push rod is in original position，The first order step of push rod end is positioned at fixing cylinder base through push-rod hole，It is provided with magnet steel installing mechanism away from the side of magnet steel delivery device at fixing cylinder base，Described magnet steel installing mechanism includes being fixed on the transfer gantry installed on table top，The bottom of transfer gantry is provided with speaker framework location seat，The top of transfer gantry is provided with vertical conveying cylinder，The piston rod carrying cylinder downward is made up of nonferromagnetic material，The inside of piston rod is provided with coaxially can the electric magnet of Self-resetting，The lower surface of the iron core of electric magnet flushes with piston-rod lower end face，The lower surface of iron core is less than the end face of magnet steel，When push rod is in final position，The terrace of appearing on the stage of the first order step of push rod end is positioned at below piston-rod lower end face，And the distance appeared on the stage between terrace and piston-rod lower end face is equal to the height of magnet steel.
In this scheme, owing to when original position, the first order step of push rod end is positioned at fixing cylinder base, thus the magnet steel putting into the sleeve that magnetizes can be laminated on the first order step surface of push rod end.When push rod is in final position, the magnet steel of bottom is pushed out magnet steel and exports and rest on the first order step surface of push rod end.Owing to the distance appeared on the stage between terrace and piston-rod lower end face of the first order step of push rod end is equal to the height of magnet steel, therefore, the upper surface now resting on the magnet steel on the first order step surface of push rod end just flushes with piston-rod lower end face and fits, so that magnet steel adsorbs in piston rod on the iron core of electric magnet, push rod then can retreat and be returned to original position.When piston rod moves down, magnet steel can be put into lower section be positioned in the magnetic bowl of the speaker skeleton on speaker framework location seat, electric magnet energized action now, iron core moves, and the stop of the magnet steel piston rod end face by being made up of nonferromagnetic material separates with iron core.When horizontal reset on piston rod, magnet steel is i.e. deposited in the magnetic bowl of speaker skeleton, thus can be automatically performed the installation of magnet steel.
As preferably, the end of described piston rod is provided with the spacing raised line of V-arrangement, and the opening of the spacing raised line of V-arrangement is rectified magnet steel outlet.
When magnet steel is released by push rod, magnet steel can be played positioning action by the spacing raised line of V-arrangement, thus is conducive to making magnet steel enter precisely in the magnetic bowl of speaker skeleton, it is ensured that installation procedure is efficiently and accurately.
As preferably, the bottom of described conveying cylinder is provided with fixes the magnet steel fairlead being connected with transfer gantry, and magnet steel fairlead is coaxial with piston rod, and the cross section of magnet steel fairlead endoporus is suitable with the cross section of magnet steel.
So, when piston rod is descending, magnet steel is put into magnet steel fairlead, magnet steel is under gravity, enter precisely in the magnetic bowl of speaker skeleton along magnet steel fairlead, thus can avoid producing between piston rod end and the speaker skeleton that profile is bigger interfering, reduce the restriction of the overall dimensions of the electric magnet to piston rod inner.
The magnet steel installation method of a kind of speaker, comprises the steps:
The most first magnet steel blank is sequentially placed into one and is magnetized in sleeve by what nonferromagnetic material was made, this sleeve that magnetizes has a capping threadeded with its opening, then the sleeve that will magnetize capping of screwing on is put in magnet charger and is magnetized magnet steel blank, so that the magnet steel blank magnetized in sleeve becomes magnet steel；
B. having opened the capping of the sleeve one end of magnetizing magnetized, the sleeve openings that magnetizes the most vertically be screwed onto on a fixing cylinder base installing table top, in the sleeve that makes to magnetize, the magnet steel of bunchiness is laminated on the bottom surface of fixing cylinder base；
The magnet steel of the fixing cylinder base side of magnet steel release of bottommost is exported by the push rod c. made with a nonferromagnetic material；
D., the magnet steel releasing magnet steel outlet is put into the magnetic bowl of speaker skeleton, and the magnet steel that can complete speaker is installed.
Owing to the magnet steel after magnetizing can mutually be attached together, need when therefore installing first to be separated, and the polarity distinguishing magnet steel just can be installed in the magnetic bowl of speaker skeleton.The magnet steel blank that first needs are magnetized by the present invention is encapsulated in one and is magnetized in sleeve by what nonferromagnetic material was made, then the magnet steel blank magnetized in sleeve is carried out entirety to magnetize, from the characteristic of Magnet, when magnet steel is separated from each other, its pole orientation keeps constant, in this way it can be ensured that the polarity of every magnet steel is identical, and without distinguishing artificially, it is to avoid dress phenomenon by mistake occurs during installation.In addition magnetizing sleeve can be simultaneously as the packing container of magnet steel, only need to be by the sleeve connection that magnetizes on fixing cylinder base during installation, i.e. may utilize push rod to be released one by one by magnet steel, thus be conducive to simplifying installation procedure, moving back and forth of push rod, may utilize cylinder and promotes, or driven by drive mechanism by motor, to improve installation effectiveness further.Owing to magnetizing sleeve and push rod is made by nonferromagnetic material, therefore can avoid magnet steel and magnetize sleeve and push rod produces adsorption.
As preferably, in step c, described fixing cylinder base is provided with the magnet steel mounting table being made up of nonferromagnetic material in the downside that magnet steel exports, there is on the upside of the end of push rod a rectangular indentation, so that push rod end is two grades step-like, when push rod enters in fixing cylinder base, the magnet steel of bottom is first released magnet steel and is exported and rest on magnet steel mounting table by its less end, now the magnet steel in magnet steel sleeve automatically falls and is pressed on the first order step surface of push rod end, push rod continues reach, the magnet steel of bottom is released magnet steel and is exported and make magnet steel rest on the first order step surface of push rod end by the second level step of its end again, thus during the one-off of push rod, release two magnet steel simultaneously and separated.
Owing to push rod can release two magnet steel during once pushing simultaneously, and two magnet steel lay respectively on the first order step surface of magnet steel mounting table and push rod end, therefore can avoid mutually adsorbing between two magnet steel, two magnet steel can be installed in the magnetic bowl of speaker skeleton by operator the most simultaneously, thus can significantly increase installation effectiveness.
Therefore, there is advantages that production efficiency is high and easily is automated production, the reverse installation that magnet steel occurs when installing can be avoided simultaneously.

Detailed description of the invention
The present invention will be further described with detailed description of the invention below in conjunction with the accompanying drawings.
Embodiment 1: the magnetic steel mounting device of a kind of speaker, as shown in Figure 1, including an installation table top 1, installing, on table top, fixing cylinder base 2 and magnet steel delivery device 3 are set abreast, fixing cylinder base is spirally connected vertically in the upper end of opening a cylindrical sleeve 4 that magnetizes, the sleeve that magnetizes preferably can be made with aluminium alloy, in order to is made by extrusion molding mode.As shown in Figure 2, the sleeve that magnetizes arranges the capping 41 of sealing at two ends, and the lower end of the sleeve that magnetizes is external screw thread, upper end is female thread, and correspondingly the capping of lower end is female thread, the capping of upper end is external screw thread, so, on the one hand cover to be formed with the sleeve that magnetizes and threaded, on the other hand, by arranging corresponding female thread on fixing cylinder base, when being threaded on fixing cylinder base after the capping opening sleeve lower end of magnetizing.Particularly, when, after the capping removing a sleeve lower end of magnetizing, linking together with another bush whorl that magnetizes removing upper end capping.
As it is shown on figure 3, magnet steel delivery device 3 includes a transversely movable push rod 31 and drives the movable power source 32 of push rod, as it was previously stated, power source can be cylinder or motor combines drive mechanism, thus automatically moving of push rod can be conveniently realized.Push rod has the final position after an original position and reach, and fixing cylinder base arranges the push-rod hole 21 suitable with push rod in the side corresponding with push rod, and the opposite side of fixing cylinder base then arranges the magnet steel relative with a push-rod hole outlet 22.During installation, can first magnet steel 7 mutually be adsorbed into a string by identical pole orientation, then magnet steel string is put into the sleeve 4 that magnetizes, sleeve connection will be magnetized again on fixing cylinder base 2, magnet steel string i.e. automatic stack pressure now is on the bottom surface of fixing cylinder base, power source drives pushrod advances to final position, and bottommost magnet steel can be released magnet steel outlet by push rod, operator can directly catch magnet steel and put it into speaker skeleton magnetic bowl in complete to install.When the magnet steel in the sleeve that magnetizes will push complete, directly the magnet steel string put in order can be put into the sleeve that magnetizes being connected on fixing cylinder base.It is understood that magnetize, sleeve, push rod and fixing cylinder base preferably should be made up of nonferromagnetic material, to avoid mutually adsorbing with magnet steel.Certainly, in order to improve efficiency, the magnet steel blank that needs can first be magnetized by we is put into and is magnetized in sleeve, then it is put into magnet charger entirety to magnetize, after completing to magnetize, the magnet steel in sleeve that magnetizes i.e. has identical pole orientation, thus can remove collating program of magnet steel from.When needing to install, only need to directly by the sleeve connection that magnetizes on fixing cylinder base, when the magnet steel in the sleeve that magnetizes will push complete, only need to open the capping of another sleeve that magnetizes, the magnet steel that it is internal be poured into and is connected to magnetizing in sleeve on fixing cylinder base.
Additionally, for the ease of operation, when avoiding installing, there is mistake in the pole orientation of magnet steel, we can arrange, in the downside of fixing cylinder base magnet steel outlet, the magnet steel mounting table 23 that a nonferromagnetic material is made, this magnet steel mounting table has the upper surface of a level, and magnet steel mounting table upper surface should flush or more lower slightly than the lower edge of magnet steel outlet with the lower edge of magnet steel outlet, so, when magnet steel is released magnet steel outlet by push rod, magnet steel can arrive smoothly and rest on magnet steel mounting table, consequently facilitating magnet steel is put in the magnetic bowl of speaker skeleton by operator.
Further, we also can arrange a rectangular indentation 311 on the upside of the end of push rod, so that push rod end is two grades step-like.So, when pushrod advances, the magnet steel of bottom is first released magnet steel and is exported and rest on magnet steel mounting table by its less end, now the magnet steel in magnet steel sleeve automatically falls and is pressed on the first order step surface of push rod end, under the promotion of the second level step of push rod end, the magnet steel being pressed on the first order step surface of push rod end is pushed out magnet steel and exports and remain on the first order step surface of push rod end, thus can release two magnet steel during the one-off of push rod simultaneously and be separated.Certainly, we must make height that magnet steel the exports height less than two magnet steel, thus avoids occurring that two magnet steel are pushed out the phenomenon of magnet steel outlet simultaneously during the magnet steel bottom promoting of end that push rod is less.It addition, the height of magnet steel outlet must also be more than the height sum of the height of a magnet steel with push rod end first order step, so that it is guaranteed that successfully release from magnet steel exit in the magnet steel being pressed on the first order step surface of push rod end.It is understood that the height of the first order step of push rod end should be less than the height of magnet steel.
In addition, we can install the delivery track arranging annular on table top, on delivery track, it is positioned apart from some speaker framework location seats simultaneously, so, cycle operation along with delivery track, mounted speaker skeleton can be taken off simultaneously by another operator while speaker skeleton being placed on the speaker framework location seat of delivery track, thus realizes the continuous installation of magnet steel.Certainly, delivery track may be connected to the station of next procedure, to realize the automated production of speaker.
Embodiment 2: the magnetic steel mounting device of a kind of speaker, as shown in Figure 4, Figure 5, it includes an installation table top 1 equally, is arranged side by side at the fixing cylinder base 2 and magnet steel delivery device 3 installed on table top, as different from Example 1, without arranging magnet steel mounting table on fixing cylinder base.In order to realize the automatic installation of magnet steel, we can arrange magnet steel installing mechanism 6 at fixing cylinder base away from the side of magnet steel delivery device, magnet steel installing mechanism includes being fixed on the transfer gantry 61 installed on table top, the top of transfer gantry arranges a vertical conveying cylinder 62, and one of them the speaker framework location seat 51 of the delivery track 5 being positioned at transfer gantry bottom is corresponding with conveying cylinder.The piston rod 621 carrying cylinder downward is made up of the nonferromagnetic material of aluminium alloy, rustless steel one class, piston rod uses cylindrical structure, inside cavity in the middle of the piston rod be coaxially disposed a band Self-resetting spring thus can the electric magnet 63 of Self-resetting, the lower surface of the iron core 631 of electric magnet flushes with piston-rod lower end face.In addition, same as in Example 1ly, we can arrange a rectangular indentation 311 on the upside of the end of push rod, so that push rod end is two grades step-like, and when push rod is in original position, the first order step of push rod end is positioned at fixing cylinder base through push-rod hole.When push rod is in final position, the terrace of appearing on the stage of the first order step of push rod end is positioned at below piston-rod lower end face, and the distance appeared on the stage between terrace and piston-rod lower end face is equal to the height of magnet steel.So, when connect on fixing cylinder base equipped with magnet steel magnetize sleeve time, magnetize the magnet steel string in sleeve and automatically fall and be laminated on the first order step surface of push rod end.During installation, pushrod advances to final position, thus sent by the magnet steel of bottom, the magnet steel being now sent just fits in the piston-rod lower end face of conveying cylinder attracted with the electromagnet core in piston rod.When push rod retreats to initial position, magnet steel continues absorption on iron core, now conveying cylinder action, piston rod band motor magnet and magnet steel are descending, make magnet steel enter in the magnetic bowl of speaker skeleton, then electric magnet energized action, iron core moves up, and magnet steel is separated with iron core by the prevention of piston rod and rests in the magnetic bowl of speaker skeleton, then horizontal reset on piston rod, and electric magnet power-off restoration, thus it is that the installation of next magnet steel is ready.
It is understood that the lower surface of iron core should be less than the end face of magnet steel, in order to magnet steel separates with iron core.Preferably, piston rod and iron core all use cylindrical structure, and the edge of the lower end of piston rod arranges fillet, in order to the lower surface that can successfully against piston rod when push rod sends magnet steel is moved.Additionally, we can pass through the mobile beat of a Programmable Logic Controller delivery track easily, push rod and the movement of conveying cylinder and the action etc. of electric magnet, thus realize the automatic installation of magnet steel.
Further, as it is shown in fig. 7, we also can arrange the spacing raised line of V-arrangement 622 in the end that piston rod is downward, the opening of the spacing raised line of this V-arrangement is rectified magnet steel outlet.So, when magnet steel is released by push rod, magnet steel can be played location and centering effect by the spacing raised line of V-arrangement, thus is conducive to making magnet steel enter precisely in the magnetic bowl of speaker skeleton.Preferably, we can arrange spring between push rod and power source, so that forming axial elastic connection between the two, thus avoids being formed between the stroke raised line spacing with V-arrangement of push rod interfering and conflicting.
Finally, as shown in Figure 6, we also can arrange the magnet steel fairlead 64 that be connected fixing with transfer gantry 61 in the bottom of conveying cylinder, and magnet steel fairlead is coaxial with piston rod, and the cross section of magnet steel fairlead endoporus is suitable with the cross section of magnet steel.So, when piston rod is descending, magnet steel is first put into magnet steel fairlead, magnet steel is under gravity, enter precisely in the magnetic bowl of speaker skeleton along magnet steel fairlead, thus can avoid producing between piston rod end and the speaker skeleton that profile is bigger interfering, reduce the restriction of the overall dimensions of the electric magnet to piston rod inner.Certainly, the lower end of magnet steel fairlead should be close proximity to the magnetic bowl of speaker skeleton, so that it is guaranteed that magnet steel can be reliably in the magnetic bowl of speaker skeleton.
Embodiment 3: the magnet steel installation method of a kind of speaker, specifically includes following steps:
The most first magnet steel blank is sequentially placed into one and is magnetized in sleeve by what nonferromagnetic material was made, this sleeve that magnetizes has a capping threadeded with its opening, then the sleeve that will magnetize capping of screwing on is put in magnet charger and is magnetized magnet steel blank, so that the magnet steel blank magnetized in sleeve becomes magnet steel.The magnet steel in sleeve that now magnetizes forms the magnet steel string that polarity is identical and is mutually attached together, and the sleeve that magnetizes then constitutes the storing containers of magnet steel.Owing to the cross section of magnet steel is typically circle, therefore, magnetize sleeve preferably by suitable cylindrical tube structure, when the cross section of magnet steel is the shapes such as rectangle, the lumenal cross-section of sleeve of magnetizing is suitable with the cross section of magnet steel, the profile of sleeve of magnetizing can be then cylinder, consequently facilitating and capping threaded.It addition, magnetize, sleeve preferably can be made with aluminium alloy, in order to made the shell portion in the middle of the sleeve that magnetizes by extrusion molding mode, then in two ends capping sealing to make the complete sleeve that magnetizes, thus be conducive to simplifying the processing and manufacturing program of the sleeve that magnetizes.
B. having opened the capping of the sleeve one end of magnetizing magnetized, the sleeve openings that magnetizes the most vertically be screwed onto on a fixing cylinder base installing table top, in the sleeve that makes to magnetize, the magnet steel of bunchiness is laminated on the bottom surface of fixing cylinder base.The side of this fixing cylinder base is provided with magnet steel outlet, and relative opposite side then can arrange a push-rod hole, in order to released from magnet steel exit by magnet steel.
The magnet steel of the fixing cylinder base side of magnet steel release of bottommost is exported by the push rod transverse shifting c. made with a nonferromagnetic material.It should be noted that the movement of push rod can realize manually, the most then cylinder can be used to promote, to improve efficiency and to reduce labor intensity.And fix the bottom surface in cylinder base and should flush, so that it is guaranteed that magnet steel is released smoothly from magnet steel exit with the lower edge of magnet steel outlet.Certainly, fixing cylinder base also should use aluminium alloy, the nonferromagnetic material of rustless steel one class to make.When magnet steel is released from magnet steel exit, operator can directly catch magnet steel, or, preferably we can arrange, in the downside that the magnet steel of fixing cylinder base exports, the magnet steel mounting table being made up equally of nonferromagnetic material, the upper surface of magnet steel mounting table is horizontally disposed with, so, the magnet steel releasing magnet steel outlet can smoothly rest on magnet steel mounting table, to avoid magnet steel upset occur.Certainly, magnet steel mounting table upper surface now should flush or more lower slightly than the lower edge of magnet steel outlet with the lower edge of magnet steel outlet.Further, we also can arrange a rectangular indentation on the upside of the end of push rod, so that push rod end is two grades step-like.So, when push rod enters in fixing cylinder base, the magnet steel of bottom is first released magnet steel and is exported and rest on magnet steel mounting table by its less end, now the magnet steel in magnet steel sleeve automatically fall and be pressed in push rod end first order step appear on the stage on terrace, push rod continues reach, the second level step of its end again the magnet steel of bottom is released magnet steel export and make magnet steel rest on push rod end first order step appear on the stage on terrace, thus release during the one-off of push rod simultaneously and be separated from each other between two magnet steel, and two magnet steel.
D. the magnetic bowl of speaker skeleton put into by the magnet steel releasing magnet steel outlet by operator with hands, and the magnet steel that can complete speaker is installed.Additionally, a dismountable guide pin bushing can be arranged on the magnetic bowl of speaker skeleton, consequently facilitating magnet steel is entered into by conducting in the magnetic bowl of speaker skeleton, again guide pin bushing is unloaded after installing.
It should be noted that, we can install the delivery track arranging annular on table top, on delivery track, it is positioned apart from the detent mechanism for locating speaker skeleton simultaneously, so, by another operator, speaker skeleton can be placed on the detent mechanism of delivery track, thus the continuous installation of magnet steel can be realized.
