(160) and a pair of right electromagnet modules 160 are sequentially driven to implement a shaking motion in the left and right directions.
그리고 본 실시예에 따른 멀티 모션 교반기(100)는, 도 7에 도시된 바와 같이 교반유닛(120)의 좌측 및 우측에 2개씩 배열된 영구자석모듈(150)에 대응되는 좌측 한 쌍의 전자석모듈(160) 및 우측 한 쌍의 전자석모듈(160)을 순차적으로 구동시키는 과정을 기 설정된 시간 동안 수행한 뒤, 교반유닛(120)의 전방 및 후방에 2개씩 배열된 영구자석모듈(150)에 대응되는 전방 한 쌍의 전자석모듈(160) 및 후방 한 쌍의 전자석모듈(160)을 순차적으로 구동시키는 과정을 기 설정된 시간 동안 수행할 수 있다.And the multi-motion stirrer 100 according to this embodiment, as shown in FIG. 7 , a pair of left electromagnet modules corresponding to the permanent magnet modules 150 arranged two by two on the left and right sides of the stirring unit 120 . After performing the process of sequentially driving 160 and the pair of right electromagnet modules 160 for a preset time, corresponding to the permanent magnet modules 150 arranged two each at the front and rear of the stirring unit 120 A process of sequentially driving a pair of front electromagnet modules 160 and a pair of rear electromagnet modules 160 to be used may be performed for a preset time.
더불어 본 실시예에 따른 멀티 모션 교반기(100)는, 도 8에 도시된 바와 같이 교반유닛(120)에 구비되는 각각의 영구자석모듈(150)에 대응되는 각각의 전자석모듈(160)을 동시에 구동시켜, 교반유닛(120)의 전체 면적에 걸친 빠른 진동을 구현하도록 할 수 있다.In addition, the multi-motion stirrer 100 according to this embodiment simultaneously drives each electromagnet module 160 corresponding to each permanent magnet module 150 provided in the stirring unit 120 as shown in FIG. 8 .

이와 같은 전체 진동 모션은 일정한 패턴으로 지속될 수도 있으며, 또는 무작위 패턴에 의해 불규칙한 패턴으로 지속될 수도 있을 것이다.Such an overall vibration motion may be continued in a constant pattern or may be continued in an irregular pattern by a random pattern.
즉 본 발명은 복수 개의 전자석모듈(160) 및 영구자석모듈(150) 각각을 프로그래밍을 통해 다양한 방식으로 제어할 수 있으므로, 위와 같은 다수의 모션을 용이하게 구현할 수 있는 장점을 가진다.That is, the present invention has the advantage of being able to easily implement a plurality of motions as described above because each of the plurality of electromagnet modules 160 and the permanent magnet module 150 can be controlled in various ways through programming.
이상으로 본 발명의 제1실시예에 대해 설명하였으며, 이하에서는 본 발명의 다른 실시예에 대해 설명하도록 한다.The first embodiment of the present invention has been described above, and another embodiment of the present invention will be described below.
도 9는 본 발명의 제2실시예에 따른 멀티 모션 교반기(100)의 모습을 나타낸 도면이다.9 is a view showing the state of the multi-motion stirrer 100 according to the second embodiment of the present invention.
도 9에 도시된 본 발명의 제2실시예의 경우, 전술한 제1실시예와 전체적으로 동일한 구성요소를 가지도록 형성된다.In the case of the second embodiment of the present invention shown in Fig. 9, it is formed to have the same components as those of the first embodiment described above.
다만, 본 실시예의 경우 교반유닛(120)에는 교반 대상을 흡착시킬 수 있도록 흡입력을 발생시키는 별도의 흡입유닛과 연결되는 흡착홀(144)이 형성된다는 부가적인 특징을 가진다.However, in the present embodiment, the agitation unit 120 has an additional feature that an adsorption hole 144 connected to a separate suction unit generating a suction force is formed to adsorb the object to be stirred.
이와 같은 흡착홀(144)은 커버플레이트(140)에만 형성될 수도 있으며, 또는 커버플레이트(140) 및 고정플레이트(130)에 동시에 형성될 수도 있다. 즉 본 실시예는 흡착홀(144)을 통해 교반 대상을 흡착함에 따라, 진동에 의해 교반 대상의 위치가 변화하는 것을 방지할 수 있다.The suction hole 144 may be formed only on the cover plate 140 , or may be formed simultaneously on the cover plate 140 and the fixing plate 130 . That is, in the present embodiment, as the stirring object is adsorbed through the adsorption hole 144 , it is possible to prevent the position of the stirring object from being changed due to vibration.
도 10은 본 발명의 제3실시예에 따른 멀티 모션 교반기(100)에 있어서, 영구자석모듈(150)의 고정 구조를 나타낸 도면이다.10 is a view showing the fixed structure of the permanent magnet module 150 in the multi-motion stirrer 100 according to the third embodiment of the present invention.
도 10에 도시된 본 발명의 제3실시예의 경우 역시 마찬가지로, 전술한 제1실시예와 전체적으로 동일한 구성요소를 가지도록 형성된다.The third embodiment of the present invention shown in FIG. 10 is also formed to have the same components as those of the first embodiment described above.
다만, 본 실시예의 경우 영구자석모듈(150)이 삽입되는 고정플레이트(130)의 삽입홈(132)은, 고정플레이트(130)의 외측에서 중앙부로 갈수록 깊이가 점차 깊어지는 형태를 가지도록 형성된다.However, in the present embodiment, the insertion groove 132 of the fixing plate 130 into which the permanent magnet module 150 is inserted is formed to have a depth gradually increasing from the outside of the fixing plate 130 to the central portion.
그리고 영구자석모듈(150)이 삽입홈(132)에 삽입된 상태에서 영구자석모듈(150)의 하면과 삽입홈(132)의 바닥부 사이에 형성되는 공간에는, 탄성 변형이 가능한 완충부재(136)가 구비될 수 있다.And in a space formed between the lower surface of the permanent magnet module 150 and the bottom of the insertion groove 132 in a state in which the permanent magnet module 150 is inserted into the insertion groove 132, an elastically deformable buffer member 136 ) may be provided.
이는 전자석모듈(160)의 자기력에 의해 영구자석모듈(150)의 변위가 가변되어 교반유닛(120)이 하부 방향으로 변형될 경우, 영구자석모듈(150)이 수평을 이루지 않고 다소 기울어진 상태를 가짐에 따라 전자석모듈(160)의 자기력선에 의한 영향이 감소하는 것을 방지하기 위한 것이다.This is when the displacement of the permanent magnet module 150 is changed by the magnetic force of the electromagnet module 160 and the stirring unit 120 is deformed in the downward direction, the permanent magnet module 150 is not leveled but rather inclined. This is to prevent the effect of the magnetic force line of the electromagnet module 160 from being reduced as it has.
즉 본 실시예는 전자석모듈(160)의 자기력에 의해 영구자석모듈(150)의 변위가 가변되어 교반유닛(120)이 하부 방향으로 변형될 경우, 영구자석모듈(150)이 완충부재(136)를 압착함에 따라 영구자석모듈(150)의 하면은 삽입홈(134)의 바닥부에 보다 근접하게 되며, 따라서 교반유닛(120)의 변형과 관계없이 영구자석모듈(150)은 항상 수평 상태에 근접한 상태를 유지할 수 있게 된다.That is, in this embodiment, when the displacement of the permanent magnet module 150 is varied by the magnetic force of the electromagnet module 160 and the stirring unit 120 is deformed in the downward direction, the permanent magnet module 150 is a buffer member 136 . As the pressure is pressed, the lower surface of the permanent magnet module 150 is closer to the bottom of the insertion groove 134, and therefore, regardless of the deformation of the stirring unit 120, the permanent magnet module 150 is always close to a horizontal state. state can be maintained.
따라서 본 실시예는 영구자석모듈(150)이 전자석모듈(160)의 자기력선에 의한 영향을 일정하게 유지할 수 있도록 하는 장점을 가진다.Therefore, this embodiment has the advantage of allowing the permanent magnet module 150 to constantly maintain the influence of the magnetic force line of the electromagnet module 160 .
