[0032] One embodiment of this utility model provides a liquid debubbling device for removing air bubbles from liquids, for example, it can be applied to remove air bubbles from adhesives. In this embodiment, the liquid debubbling device includes a bubble removal mechanism, which can be referred to... Figure 1 and Figure 2 The bubble removal mechanism includes: a reaction cylinder 10, a negative pressure generator (not shown), an ultrasonic oscillator 12, a stirring element 13, and a motor 14. The reaction cylinder 10 has a receiving cavity 100 for containing liquid. The negative pressure generator is used to extract air from the receiving cavity 100, making it easier for bubbles in the liquid to detach. The ultrasonic oscillator 12 is used to transmit the bubble vibration to the liquid surface, working in conjunction with the vacuum created by the negative pressure generator to achieve a defoaming effect. The stirring element 13 is used to stir the liquid to ensure more thorough defoaming.

[0033] Specifically, the ultrasonic oscillator 12 is rotatably disposed in the receiving cavity 100, the stirring element 13 is fixed to the outer periphery of the ultrasonic oscillator 12, and the output shaft 141 of the motor 14 is fixed to the ultrasonic oscillator 12 to drive the ultrasonic oscillator 12 to rotate, thereby driving the stirring element 13 to stir the liquid in the receiving cavity 100.

[0034] In this embodiment, the oscillation effect of the ultrasonic oscillator 12 causes the air bubbles in the liquid to be transferred to the liquid surface. In addition, the negative pressure generator evacuates the receiving cavity 100 of the reaction cylinder 10, and the stirring element 13 stirs the liquid. The three parts work together to effectively remove the air bubbles in the liquid.

[0035] In one specific embodiment, the reaction cylinder 10 includes a cylinder body 101 and a cylinder cover 102. The motor 14 is fixed to the side of the cylinder cover 102 away from the cylinder body 101, and the cylinder cover 102 has a through hole 1021 in the middle. The motor 14 is mounted outside the reaction cylinder 10. Since the output shaft 141 of the motor 14 needs to be connected to the ultrasonic oscillator 12, the motor 14, the ultrasonic oscillator 12, or the connecting parts for connecting the two need to pass through the cylinder cover 102. The through hole 1021 can be used for the output shaft 141 of the motor 14 to pass through, or for a part of the ultrasonic oscillator 12 to pass through, or for the wire of the ultrasonic oscillator 12 to pass through.

[0036] Preferably, refer to Figure 3 The bubble removal mechanism also includes a heating module 24 and a cooling module 25, which are spaced apart from each other and located on the outer periphery of the cylinder body 101. These modules are used to regulate the temperature of the cylinder body 101, thereby providing a stable ambient temperature for the adhesive in the receiving cavity 100 according to the properties of the adhesive. A safety valve 26 and a pressure regulating valve 27 are also correspondingly provided on the cylinder cover 102 to maintain the gas pressure in the receiving cavity 100 of the reaction cylinder 10 within a relatively safe range, thus ensuring the safety of the bubble removal process.

[0037] Preferably, further reference can be made. Figure 3 A liquid level sensor 28 is provided on the upper and lower sides of the side wall of the cylinder body 101. The upper liquid level sensor 28 is located above the heating module 24 and the cooling module 25, and the lower liquid level sensor 28 is located between the heating module 24 and the cooling module 25. More preferably, in order to increase the area of ​​the heating module 24 and the cooling module 25 in contact with the cylinder body 101, a clearance groove is formed between the heating module 24 and the cooling module 25 to avoid the lower liquid level sensor 28, thereby reducing the gap between the heating module 24 and the cooling module 25 above the clearance groove.

[0038] More specifically, please refer to Figure 2 The bubble removal mechanism also includes an ultrasonic sleeve 15, which is fixed to the ultrasonic oscillator 12. A portion of the ultrasonic sleeve 15 is located in the receiving cavity 100, and a portion extends out of the receiving cavity 100 through the through hole 1021 and is fixed to the output shaft 141 of the motor 14.

[0039] More specifically, the bubble removal mechanism also includes a mounting base 16, which is fixed to the side of the cylinder cover 102 away from the cylinder body 101. The motor 14 is fixed to the end of the mounting base 16 away from the cylinder cover 102. The ultrasonic sleeve 15 is provided with a first wire passage hole 151, and the mounting base 16 is provided with a second wire passage hole 161. The wire of the ultrasonic oscillator 12 is led out from the ultrasonic sleeve 15 and passes through the first wire passage hole 151 and the second wire passage hole 161 in sequence to extend out of the mounting base 16.

The connecting sleeve 18 is fixed to the end of the cylinder cover 102 away from the cylinder body 101, and the mounting seat 16 is fixed to the end of the connecting sleeve 18 away from the cylinder cover 102. The connecting sleeve 18 blocks a part of the through hole 1021 to prevent the bearing 17 from disengaging from the through hole 1021.

[0041] Preferably, the bubble removal mechanism further includes a conductive slip ring 19, which is located on the inner circumference of the connecting sleeve 18 and the mounting base 16, with a portion of the sleeve located on the inner circumference of the conductive slip ring 19. The conductive slip ring 19 facilitates the lead-out of the wire and prevents the wire from breaking during rotation.

[0042] Preferably, the bubble removal mechanism further includes a connecting cylinder 20, which connects the output shaft 141 of the motor 14 to the ultrasonic sleeve 15. The connecting cylinder 20 has a connecting hole extending axially in the middle. The output shaft 141 of the motor 14 extends into the connecting hole from one end of the connecting cylinder 20, and the ultrasonic sleeve 15 extends into the connecting hole from the other end of the connecting cylinder 20.

[0043] In one specific embodiment, the stirring component 13 includes a connecting ring 131 and a plurality of stirring paddles 132. The stirring paddles 132 are connected to the connecting ring 131. The connecting ring 131 is fixed to the outer periphery of the ultrasonic oscillator 12, and the plurality of stirring paddles 132 are distributed on the outer periphery of the connecting ring 131.

[0044] In a preferred embodiment, the bubble removal mechanism further includes a bubble detection mechanism, which can be used to detect the presence of bubbles in the liquid. This mechanism can be installed before or after the bubble removal process. (See reference...) Figure 4The bubble detection mechanism includes a CCD camera 31, a bubble observation box 32, and a light source 33. The bubble observation box 32 is connected to the reaction cylinder 10. The bubble observation box 32 can be used to receive the liquid that has undergone the degassing process in the reaction cylinder 10 and to detect the degassing effect, or it can be used to detect the presence of bubbles in the liquid beforehand and then transfer the liquid containing bubbles to the reaction cylinder 10 for the degassing process. Specifically, the bubble observation box 32 is located between the CCD camera 31 and the light source 33. The light from the light source 33 passes through the bubble observation box 32 and enters the CCD camera 31 to observe whether bubbles are present inside the bubble observation box 32.

[0045] Preferably, the bubble observation box 32 can be made of a light-transmitting material, and both the top of the bubble observation box 32 and the bottom of the support for supporting the bubble observation box 32 are provided with a circular clearance hole to improve the light propagation effect. The bubble detection mechanism can also be equipped with a light shield to enclose and block the CCD camera 31, the bubble observation box 32 and the light source 33 to improve the observation effect.

[0046] Preferably, the bubble observation box 32 is used to receive the liquid in the reaction cylinder 10 after the degassing process to detect the degassing effect of the liquid. Specifically, the cylinder cover 102 is provided with a liquid inlet 21 for adding liquid. The opening of the liquid inlet 21 is provided with a sealing cap 22, which can seal the opening of the liquid inlet 21 after the liquid is added. The cylinder body 101 is provided with a liquid outlet pipe 23 on the side opposite to the cylinder cover 102. The bubble observation box 32 is provided with a liquid inlet pipe 321, a first drain pipe 322, and a second drain pipe. The liquid in the reaction cylinder 10 flows out from the liquid outlet pipe 23, passes through the screw valve, and flows into the liquid inlet pipe 321. The first drain pipe 322 and the second drain pipe 323 are respectively used to send the tested liquid to different subsequent work stations. For example, when air bubbles are detected in the liquid, the system can control the liquid to be sent to the recycling tank through the first drain pipe 322 for subsequent air bubble removal. When no air bubbles are detected in the liquid, the system can control the liquid to be sent to the subsequent encapsulation liquid process or dispensing process through the second drain pipe 323.
