In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1
Referring to fig. 1 to fig. 3, the present embodiment provides a sealant de-foaming apparatus 100, including:
a defoaming cavity 1; the defoaming cavity 1 is suitable for defoaming the pouring sealant; a defoaming chamber piston 11 is arranged in the defoaming chamber 1, the outer diameter of the defoaming chamber piston 11 is equal to the inner diameter of the defoaming chamber 1, and the defoaming chamber piston 11 is suitable for moving up and down in the defoaming chamber 1 along the vertical direction. The defoaming chamber 1 may be a defoaming tub, for example.
A position measuring cavity 2; the position measuring cavity 2 is internally provided with a cylinder piston 21, the outer diameter of the cylinder piston 21 is equal to the inner diameter of the position measuring cavity 2, and the cylinder piston 21 is suitable for moving up and down in the position measuring cavity 2 along the vertical direction. The positioning cavity 2 may be a cylinder, for example.
The top of the defoaming cavity piston 11 is provided with a defoaming cavity piston support rod 3, and the defoaming cavity piston support rod 3 extends out of the defoaming cavity 1 along the vertical direction. The top of the cylinder piston 21 is provided with a cylinder piston supporting rod 4, and the cylinder piston supporting rod 4 extends out of the position measuring cavity 2 along the vertical direction. The top of the piston support rod 3 of the defoaming cavity is connected with the top of the piston support rod 4 of the cylinder through a piston connecting rod 5.
The sealant pouring deaeration device provided in this embodiment connects the deaeration chamber piston rod 3 and the cylinder piston rod 4 into an integrated structure by the piston rod 5, and further connects the deaeration chamber piston 11 and the cylinder piston 21 into an integrated structure. When the defoaming chamber piston 11 moves up and down in the defoaming chamber 1 in this way, the cylinder piston 21 also moves up and down in the cavity of the positioning chamber 2 along with the defoaming chamber piston 11. Therefore, when the liquid level of the potting adhesive in the defoaming chamber 1 changes, the air pressure in the defoaming chamber 1 changes, so that the piston 11 of the defoaming chamber moves up and down along with the change to maintain the normal air pressure in the defoaming chamber 1, and at the same time, the piston 21 of the air cylinder moves up and down along with the change in the position measuring chamber 2. Therefore, the position variation of the defoaming chamber piston 11 in the defoaming chamber 1 can be obtained according to the position variation of the cylinder piston 21 in the positioning chamber 2, and the variation of the storage quantity of the pouring sealant in the defoaming chamber 1 can be further converted. So that the measurement of the liquid level position of the pouring sealant in the defoaming cavity 1 is converted into the position measurement of the cylinder piston 21. The measurement of the position of the cylinder piston 21 can be obtained by timely and accurately measuring through various methods, so that the storage amount of the pouring sealant in the defoaming cavity 1 can be obtained by timely and accurately measuring.
In the embodiment, there are two positioning cavities 2, each positioning cavity 2 is provided with a cylinder piston 21, and the top of each cylinder piston 21 is provided with a cylinder piston strut 4; the piston connecting rod 5 is connected with the top of the piston supporting rod 3 of the defoaming cavity and the top of the two cylinder piston supporting rods 4. The arrangement of the two position measuring cavities 2 enables the piston 11 of the defoaming cavity to move to drive the two cylinder pistons 21 to follow up, so that the required kinetic energy is higher and more stable. The change in position of the two following cylinder pistons 21 is thus more accurate than the change in position of one following cylinder piston 21.
Furthermore, two position measuring cavities 2 are respectively arranged at two sides of the defoaming cavity 1, and a piston support rod 3 of the defoaming cavity is positioned in the middle of a horizontal connecting line of two piston support rods 4 of the cylinder. Set up deaeration cavity piston branch 3 in the centre of 4 horizontal lines of cylinder piston branch for deaeration cavity piston branch 3 is the same to two cylinder piston branch 4's distance, makes two cylinder piston 21 atress more even like this, removes more steadily, and the measurement of the change of position is more accurate.
In the present embodiment, the inner wall of the position-finding cavity 2 is provided with a position sensor (not shown in the figures), which is adapted to send out a sensing signal when the cylinder piston 21 moves to a preset position in the position-finding cavity 2; the position sensor is connected with an alarm device (not shown in the figure) arranged outside the defoaming cavity 1, and the alarm device is suitable for sending an alarm signal when receiving the induction signal. The alarm device can be a buzzer or a warning lamp, and the alarm signal can be a buzzer or a light change correspondingly. Therefore, the position of the cylinder piston 21 does not need to be monitored at any time, the position of the cylinder piston 21 only needs to be monitored at a fixed position, and the alarm can be realized when the cylinder piston 21 reaches the position. For example, it may be set to alarm when the cylinder piston 21 reaches a preset position, indicating that the potting adhesive needs to be added. A plurality of position sensors can be arranged to realize monitoring of a plurality of positions, different alarm effects are set for different positions, and multi-stage monitoring is realized.
Specifically, the position sensor may be a contact sensor, and the contact sensor is adapted to send out a sensing signal after the cylinder piston 21 touches the contact sensor. Alternatively, the position sensor may be an infrared sensor adapted to emit a sensing signal when the cylinder piston 21 reaches a horizontal position of the infrared sensor.
In this embodiment, the sealant de-bubbling device further includes: a glue storage cavity 6; the glue storage cavity 6 is communicated with the defoaming cavity 1 through a glue conveying pipe 7. The glue storage cavity 6 can be a glue storage barrel, for example. Through the arrangement of the glue storage cavity 6, the pouring sealant can be prepared in the glue storage cavity 6, when the pouring sealant needs to be supplemented, the pouring sealant only needs to be supplemented into the glue storage cavity 6, and the defoaming cavity 1 does not need to be opened, so that on one hand, the defoaming cavity 1 can be prevented from being aged due to repeated opening and closing of the defoaming cavity 1, and further, the defoaming effect caused by aging is prevented from being reduced; on the other hand, the pouring sealant can be supplemented into the defoaming cavity 1 during the defoaming operation, so that the defoaming operation is not interrupted.
Further, the rubber delivery pipe 7 is communicated with the bottom of the rubber storage cavity 6 and the bottom of the defoaming cavity 1. The glue conveying pipe 7 is communicated with the bottom of the glue storage cavity 6 and the bottom of the defoaming cavity 1, so that on one hand, pouring glue in the glue storage cavity 6 can naturally enter the glue conveying pipe 7 under the action of gravity, and the pouring glue is supplemented into the defoaming cavity 1; on the other hand, the pouring sealant is filled into the defoaming cavity 1 from the bottom, so that redundant gas cannot be introduced, redundant bubbles cannot be caused, and the defoaming effect cannot be influenced.
Furthermore, the rubber delivery pipe 7 is provided with a one-way valve 8, so that the rubber delivery pipe 7 is communicated in one way from the rubber storage cavity 6 to the defoaming cavity 1. Through the setting of check valve 8, can guarantee that the casting glue can not take place against current from deaeration cavity 1 to storing up gluey cavity 6.
Further, the defoaming chamber 1 is a sealing device, the defoaming chamber 1 is provided with an air exhaust hole 13, and the air exhaust hole 13 is arranged at the top of the defoaming chamber 1 or at the side part close to the top of the defoaming chamber 1; the air pumping hole 13 is suitable for connecting a vacuum air pump (not shown in the figure) to perform vacuum air pumping on the defoaming chamber 1. Compared with pure air extraction defoaming, the vacuum defoaming effect is better.
Further, the defoaming chamber 1 is provided with a pouring sealant outlet 12, and the pouring sealant outlet 12 is disposed at the bottom of the defoaming chamber 1 or at a side portion close to the bottom of the defoaming chamber 1. Therefore, when the pouring sealant is used, the pouring sealant flows out from the bottom of the defoaming cavity 1, external air is blocked by the pouring sealant and cannot enter the defoaming cavity 1, and bubbles in the defoaming cavity 1 cannot be increased.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications derived therefrom are intended to be within the scope of the utility model.
