Detailed Description

The invention will be further explained with reference to the drawings.

As shown in fig. 1 to 4, according to a first aspect of the present invention, there is provided an automatic silicone oil extruding device capable of preventing silicone oil from being agglomerated and capable of automatically extruding silicone oil to facilitate taking of silicone oil. Specifically, the automatic squeezing device for silicone grease oil comprises a filter screen unit 1 and a driving unit 2, wherein the filter screen unit 1 is connected with the driving unit 2, the filter screen unit 1 moves towards a direction close to or far away from a silicone grease oil container 3 under the driving of the driving unit 2, and the silicone grease oil in a semi-solid semi-liquid state is contained in the silicone grease oil container 3.

Further, filter screen unit 1 includes filter screen 11, as shown in fig. 4, because filter screen 11 is network structure, consequently, utilize the syringe to keep away from, when network structure's filter screen 11 moves towards the direction that is close to silicone grease oil container 3 and when contacting with silicone grease oil, can extrude semisolid state semi-liquid silicone grease oil, receive extruded silicone grease oil and will see through the aperture on network structure's filter screen 11, through network structure's filter screen 11's extrusion, the silicone grease oil that emerges in network structure's filter screen 11's upper surface presents even tiny liquid state, thereby be convenient for operating personnel's taking, and guarantee the homogeneity of paining. Therefore, the automatic silicone grease extruding device can realize automatic extrusion of silicone grease, so as to reduce the labor intensity of manual extrusion of operators and the influence of uncertain factors, and improve the assembly efficiency.

Further, the diameter of the filter mesh 11 is smaller than the inner diameter of the silicone oil container 3. Therefore, when the filter unit 1 moves in a direction close to the silicone grease container 3, the filter 1 can enter the interior of the silicone grease container 3 as the silicone grease is gradually squeezed out, and the silicone grease in the silicone grease container 3 continues to be squeezed out.

The diameter of the filter net 11 can be set to 108mm for a 600ml silicone oil container 3. The mesh number of the filter net 11 may be set to 80-100, for example, 90, according to the characteristics of the silicone oil. It should be noted that the parameters such as the diameter and the mesh number can be adjusted according to actual needs, and the present invention is not limited to this.

In some embodiments, the filter unit 1 further comprises a connecting bracket 12, and the connecting bracket 12 is connected to the filter 11 and the driving unit 2 at two ends. Specifically, the connecting bracket 12 includes an adapter plate 121 and connecting rods 122 arranged at intervals along the circumferential direction of the adapter plate 121, the bottom ends of the connecting rods 122 are connected to the filter screen 11, and the adapter plate 121 is connected to the driving unit 2.

In the embodiment shown in fig. 1, the number of the connecting rods 122 is 4, and the 4 connecting rods 122 are arranged at equal intervals in the circumferential direction of the adapter plate 121. By arranging the connecting rod 122, the upper part of the filter screen 11 can be kept in an open state, so that an operator can take the squeezed silicone oil conveniently.

Further, in order to ensure that the filter screen 11 can smoothly extrude the silicone grease, the filter screen 11 is a stainless steel filter screen 11.

In some embodiments, the driving unit 2 comprises a cylinder 21, a connecting rod 22 of the cylinder 21 is connected to the upper end of the adapter plate 121 of the filter screen unit 1, and the connecting rod 22 extends or retracts in the cylinder 21 to move the filter screen unit 1 toward or away from the silicone oil container 3.

The connecting rod 22 of the cylinder 21 and the adapter plate 121 may be fixed by a mechanical connection manner such as a threaded connection or an adhesive connection, so as to ensure that the force of the connecting rod 22 can be transmitted to the filter screen 11 through the adapter plate 121 and the connecting rod 122.

In addition, the driving unit 2 further includes a photosensitive element (not shown) disposed on the cylinder 21 and a controller (not shown, a PLC controller may be used) electrically connected to the cylinder 21, the photosensitive element is in signal connection with the controller, and when the controller receives a signal from the photosensitive element, the controller retracts the connecting rod 22 in the cylinder 21, so that the filter screen unit 1 moves away from the silicone oil container 3.

When the cylinder 21 drives the filter screen 11 to move in the silicone grease container 3 until the bottom of the silicone grease container 3 is reached, indicating that the silicone grease in the silicone grease container 3 has been completely squeezed out, the light sensor can detect that light passes through the filter screen 11, and send a signal to the controller, and the controller can control the connecting rod 22 to retract in the cylinder 21, so that the filter screen 11 leaves the silicone grease container 3 and returns to the original position, so that the light sensor can be called a photoelectric sensing switch.

In some embodiments, the device further comprises a base 4 for supporting the silicone oil container 3 and a support frame 5 arranged on the base 4, and the cylinder 21 is fixed on the support frame 5. Wherein can set up parts such as recess on the base 4 to play the effect of fixed silicone oil container 3, can guarantee the stability of silicone oil container 3, can regard as the mark position of silicone oil container 3 again, thereby be convenient for change silicone oil container 3.

The upper end of the support frame 3 is connected with the top end of the cylinder 21, so that the cylinder 21 is hung on the support frame 3. The support frame 3 may be fixedly connected to the top end of the cylinder 21 by a fastener such as a bolt.

Further, when the connecting rod 22 drives the filter screen 11 to descend so that the filter screen 11 contacts the surface of the silicone grease, the resistance for squeezing the silicone grease is large, and therefore the descending speed and time of the filter screen 11 can be set through the controller so as to ensure that the filter screen 11 moves in a uniform motion mode.

In addition, when the production line stops in production, the automatic silicone grease extruding device can be stopped by the controller.

According to a second aspect of the present invention, there is provided a method of extruding silicone oil, comprising the steps of:

in the first step, the drive unit 2 is made to drive the filter unit 1 to move in the direction of approaching the silicone oil container 3.

And secondly, when the filter screen unit 1 is contacted with the surface of the silicone grease, the controller controls the descending speed and time to ensure that the filter screen unit 1 moves in a uniform motion mode, so that the silicone grease in the silicone grease container uniformly penetrates through the filter screen unit 1.

Thirdly, when the filter screen unit 1 moves to the bottom of the silicone grease container 3, the driving unit 2 drives the filter screen unit 1 to move away from the silicone grease container 3, thereby restoring the filter screen unit 1 to the original position.

In conclusion, the automatic silicone grease extruding device disclosed by the invention adopts an automatic design idea and utilizes the principle of an injector, combines the air cylinder, the photosensitive element and the PLC, extrudes the silicone grease in the semi-solid semi-liquid state in the silicone grease container 3 through the filter screen 11, and the extruded silicone grease passes through the small holes on the filter screen 11 and floats on the upper surface of the filter screen, so that the purpose of automatically extruding the silicone grease is realized; and further, these silicone grease that receive the extrusion are even tiny liquid state, therefore be convenient for operating personnel's taking, simultaneously, when scribbling these silicone grease that receive the extrusion in motion mechanism, can guarantee the homogeneity of scribbling, operating personnel inconvenient operation and scribble inhomogeneous problem when having solved production makes the quality and the quality of air conditioner promote to the silicone grease of caking is scribbled to the part and the after-sale risk that causes can reduce.
