[0038] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

Specifically, at least part of the ultrasonic cleaning assembly 30 is arranged in the cavity surrounded by the filter assembly 20.

[0040] As can be seen, the filter barrel body 10, the filter assembly 20, the ultrasonic cleaning assembly 30 and the detection assembly 40 are arranged, and at least part of the ultrasonic cleaning assembly 30 is arranged in the barrel cavity 110; the detection assembly 40 is arranged in the barrel cavity 110, and when the detection assembly 40 detects that the liquid in the filter barrel body 10 is at or above a predetermined liquid level (the minimum liquid level for normal working of the ultrasonic vibrator rod 360) or the temperature of the ultrasonic cleaning assembly 30 is at or below a predetermined temperature (the maximum temperature for normal working of the ultrasonic vibrator rod 360), the ultrasonic cleaning assembly 30 starts working to clean the filter barrel, and when it is detected that the liquid level in the filter barrel is below the predetermined liquid level or the temperature of the ultrasonic cleaning assembly 30 exceeds the predetermined temperature, the ultrasonic cleaning assembly 30 stops working. The opening and closing of the ultrasonic cleaning assembly 30 are controlled by the high and low of the liquid level or the temperature, which avoids the phenomenon of dry burning of the vibrator rod in the ultrasonic cleaning assembly 30 due to too little liquid in the filter barrel body 10 or too high temperature of the ultrasonic cleaning assembly 30, reduces the damage risk of the ultrasonic cleaning assembly 30, is beneficial to the continuous and efficient cleaning of the filter barrel by the ultrasonic cleaning assembly 30, and greatly improves the working efficiency.

[0041] Optionally, a filter screen is arranged in the filter assembly 20, the filter screen is installed in the barrel cavity of the filter barrel body 10 and extends along the extension direction of the barrel cavity, and the filter screen is in a cylindrical shape, and the bottom end of the filter screen has a filter screen outlet.

[0042] Optionally, the internal space of the filter barrel is divided into a filter screen internal space and a filter screen external space.

[0043] As shown in Figure 2 and Figure 3 The detection assembly 40 comprises a liquid level detection module 410, which is installed at a predetermined position in the barrel cavity of the filter barrel body 10 to detect the liquid level in the barrel cavity. Specifically, the predetermined position is the minimum liquid level for normal working of the ultrasonic vibrator rod.

[0044] As shown in Figure 2 and Figure 3As shown, the filtering device further comprises an anti-mis-touch component 420, which is installed in the barrel cavity of the filtering barrel body 10; the anti-mis-touch component 420 has a liquid inlet and a protection cavity in communication with the liquid inlet, the liquid inlet is located at the bottom of the anti-mis-touch component 420, and the liquid level detection module 410 is arranged in the protection cavity, so as to prevent the liquid from splashing on the liquid level detection module 410 when the ultrasonic cleaning water is insufficient, and to prevent the mis-touch from causing the ultrasonic vibration rod 360 to continuously work and cause the dry burning phenomenon.

[0045] Specifically, the anti-mis-touch component 420 is a metal piece, in one implementation manner, as shown in Figure 2 As shown, the anti-mis-touch component 420 is welded on the inner wall of the filtering barrel body 10. In another implementation manner, as shown in Figure 3 As shown, the ultrasonic cleaning assembly 30 comprises the ultrasonic rod body 310 and the mounting flange 320 connected with each other, and the anti-mis-touch component 420 is welded on the mounting flange 320 to fix the anti-mis-touch component 420 and improve the stability of the filtering device.

[0046] The specific structure of the anti-mis-touch component 420 in the embodiment: the anti-mis-touch component 420 is a tube body, the liquid inlet is the bottom pipe opening of the tube body, and the protection cavity is the tube cavity of the tube body.

[0047] The anti-mis-touch component 420 extends from the top end of the filtering barrel body 10 towards the bottom of the filtering barrel body 10, and the length of the anti-mis-touch component 420 is one fifth to one third of the length of the filtering barrel body 10. The length of the anti-mis-touch component 420 is arranged to effectively prevent the liquid from splashing on the liquid level detection module 410 when the ultrasonic cleaning water is insufficient, to prevent the mis-touch, and to better protect the liquid level detection module 410.

[0048] As shown in Figures 2 to 3 The anti-mis-touch component 420 is a metal piece, the ultrasonic cleaning assembly 30 comprises the ultrasonic rod body 310 and the mounting flange 320 connected with each other, and the mounting flange 320 is provided with a switch through hole; the filtering device further comprises a liquid level connector 50, which is arranged on the upper side wall of the mounting flange 320, and the welded part of the liquid level connector 50 is opposite to the switch through hole; the anti-mis-touch component 420 is arranged on the lower side wall of the mounting flange 320, and the top of the anti-mis-touch component 420 is opposite to the switch through hole.

[0049] As shown in Figure 5As shown, the detection assembly 40 comprises a temperature detection module 440 arranged on the ultrasonic cleaning assembly 30 to detect the temperature of the ultrasonic cleaning assembly 30 when working, so as to avoid that the ultrasonic vibration rod 360 has a too high temperature when working and causes damage to the internal wafer.

[0050] Specifically, the filter device and the wire cutting equipment with the same can prevent the ultrasonic vibration rod 360 in the ultrasonic cleaning assembly 30 from continuously working in a waterless state in the wire cutting, so as to prevent the internal wafer from being damaged. The ultrasonic vibration rod 360 is protected by adding the liquid level detection module 410 and the temperature detection module 440 in the detection assembly 40. When the liquid in the filter barrel body 10 is higher than the detection liquid level or the temperature of the ultrasonic vibration rod is lower than the predetermined temperature, the ultrasonic cleaning assembly 30 starts to work. When it is detected that the liquid level in the barrel is lower than the predetermined liquid level or the temperature of the ultrasonic vibration rod 360 is higher than the preset temperature, the ultrasonic vibration rod 360 stops working, so as to prevent the wafer in the ultrasonic vibration rod 360 from being damaged. The filter device and the wire cutting equipment with the same can prevent the ultrasonic vibration rod 360 from continuously working in a waterless state by adding an alarm signal, reduce the damage risk caused by factors other than the ultrasonic vibration rod 360 itself, prolong the service life of the ultrasonic vibration rod 360, and ensure the production efficiency.

[0051] As shown in Figure 4 , the ultrasonic cleaning assembly 30 has an ultrasonic rod body 310 which is in a cylindrical shape. The liquid level detection module 410 is arranged on the inner wall of the filter barrel body 10. The temperature detection module 440 is attached to the ultrasonic rod body 310.

[0052] As shown in Figure 1 , Figure 3 and Figure 5 , the ultrasonic cleaning assembly 30 comprises an ultrasonic generator 340, a waterproof plug 350 and an ultrasonic vibration rod 360. The ultrasonic generator 340 is connected with the ultrasonic vibration rod 360 through a connecting cable 370. The waterproof plug 350 is installed on the connecting cable 370.

[0053] As shown in Figure 3As shown in the figure, the mounting flange 320 of the ultrasonic vibration rod 360 is welded on the ultrasonic rod body 310, the mistaken touch prevention component 420 is welded on the mounting flange 320, and the liquid level detection module 410 is installed inside the mistaken touch prevention component 420, so that when the ultrasonic cleaning water is insufficient, the liquid splashing on the liquid level detection module 410 can be prevented to cause mistaken touch, and the continuous working of the ultrasonic vibration rod 360 can be prevented to cause damage to the internal wafer.

[0054] As shown in the figure, Figure 4 As shown in the figure, the temperature detection module 440 is installed inside the ultrasonic rod body 310 to detect the temperature inside the ultrasonic rod body 310, and when the temperature exceeds the set temperature, the ultrasonic rod body 310 stops working to prevent dry burning.

[0055] As shown in the figure, Figure 1 As shown in the figure, the filter barrel cover 60 is matched with the installation opening to block the installation opening and press the filter assembly 20; the ultrasonic cleaning assembly 30 has a mounting flange 320, and the mounting flange 320 is installed on the filter barrel cover 60 through mounting screws;

[0056] As shown in the figure, Figure 1 As shown in the figure, the filter barrel body 10 is provided with a cutting fluid inlet 70, a cutting fluid outlet 80 and a sewage outlet 90, the cutting fluid inlet 70 and the cutting fluid outlet 80 are arranged on the barrel wall of the filter barrel body 10, and the sewage outlet 90 is arranged at the bottom end of the filter barrel body 10.

[0057] Specifically, the filter barrel body 10 is provided with three water inlets and outlets, namely the cutting fluid inlet 70, the cutting fluid outlet 80 and the sewage outlet 90, wherein the filter barrel ultrasonic backwashing water inlet and the sewage outlet share the sewage outlet 90.

[0058] The utility model also provides a linear cutting equipment which comprises the filter device.

[0059] Specifically, during wire cutting, the cutting fluid flows into the internal space of the filter screen in the filter tank through the cutting fluid inlet 70. After the liquid level detection module 410 detects that the liquid level has reached the designated position, the ultrasonic vibrator 360 works to clean the liquid in the tank. The cleaned liquid flows out through the external space of the filter screen and the cutting fluid outlet 80, thus achieving the cleaning and filtration of the liquid.

[0060] After wire cutting, the filter canister is ultrasonically backwashed. The backwash water enters the filter screen through the drain port 90. When the liquid level detection module 410 detects that the liquid level has reached the required level, the water supply is stopped, and the ultrasonic vibrator 360 operates to clean impurities inside the canister. After a certain rinsing time, the ultrasonic vibrator 360 stops operating, and the impurities and wastewater in the filter canister are discharged through the drain port 90.

[0061] The inlet pressure of the filter canister can be detected by the pressure detection module 100 at the filter canister inlet. The interface is compatible with pressure gauges and pressure sensors, which can reflect the degree of clogging of the filter screen inside the filter canister, and serve as the basis for ultrasonic backwashing and filter screen cleaning of the filter canister.

[0062] like Figure 5 As shown, the filtration device and wire cutting equipment of this utility model mainly consist of the following parts: ultrasonic vibrator 360, liquid inlet assembly 200, pressure detection module 100, liquid outlet control assembly 300, sewage discharge control assembly 400, and ultrasonic backwash control assembly 500. During wire cutting, the sewage discharge control assembly 400 and backwash control assembly 500 are closed, while the liquid outlet control assembly 300 is opened. The liquid used for wire cutting flows into the filter tank 10 through the liquid inlet assembly 200. The ultrasonic vibrator 360 is activated and cleans the liquid inside the tank. The cleaned liquid then flows out through the liquid outlet control assembly 300, thus achieving the filtration of the liquid used for wire cutting. After wire cutting, the filter tank 10 is ultrasonically backwashed. The backwash control component 500 is turned on, while the sewage discharge control component 400 and the liquid outlet control component 300 are turned off. The flushing water enters the filter tank 10 through the ultrasonic backwash control component 500. When the liquid level in the tank reaches a certain point, the ultrasonic backwash control component 500 is turned off, and the vibrator operates to clean the impurities inside the tank. After flushing for a certain period of time, the vibrator stops operating, and the sewage discharge control component 400 is turned on to discharge the impurities and wastewater from the filter tank 10.

[0063] The filter device and wire cutting equipment of this utility model are mainly composed of an ultrasonic vibrator 360, mounting screws, filter barrel cover 60, cutting fluid inlet 70, filter barrel body 10, cutting fluid outlet 80, drain outlet 90, filter screen, first sealing ring 11, liquid level detection module 410, second sealing ring 12, pressing component 15, third sealing ring 13, and fourth sealing ring 14.

[0064] The liquid level detection module 410 is installed at a specific position on the filter bucket to detect the liquid level in the filter bucket and provide an alarm signal to prevent the ultrasonic vibration rod 360 from dry burning.

[0065] The second sealing ring 12 is installed between the filter bucket body 10 and the filter bucket cover, the filter screen is installed in the filter bucket body 10, the pressing part 15 is pressed on the connecting part between the filter screen and the filter bucket body, and the pressing part 15 is located on the inner side of the filter bucket cover 60, the third sealing ring 13 is arranged between the pressing part 15 and the filter screen, and the third sealing ring 13 is pressed and sealed after the filter screen is pressed and fixed by the pressing part 15.

[0066] The fourth sealing ring 14 is clamped between the outer wall of the filter screen outlet and the inner wall of the filter bucket blowdown port, the fourth sealing ring 14 is pressed after the filter bucket cover 60 is closed, and the fourth sealing ring 14 is pressed by the filter screen under the pressing action of the filter bucket body when the filter bucket body 10 and the filter bucket cover 60 are locked.

[0067] In summary, the filter device and the wire cutting equipment with the same can detect the liquid level in the filter bucket body 10 and the temperature of the vibration rod, increase the alarm signal, stop the vibration rod from working when the liquid level in the bucket is too low or the temperature of the vibration rod is too high, and realize the protection function of the ultrasonic vibration rod 360.
