The workpiece is placed in the cleaning machine and is rinsed in all directions using cutting fluid and cleaning fluid, respectively, thereby achieving rapid industrial assembly line cleaning.

[0003] For example, the authorization announcement number CN205966643U discloses a cleaning liquid recovery structure of a workpiece cleaning equipment, which includes a cleaning center, the cleaning center has a closed cleaning bin, a conical cleaning liquid discharge outlet is provided at the bottom of the cleaning bin, a movable recovery box for recovering the cleaning liquid is provided directly below the cleaning liquid discharge outlet, a transition trough pipe is provided above the recovery box corresponding to the cleaning liquid discharge outlet, a cleaning liquid collecting port corresponding to the cleaning liquid discharge outlet is provided on the upper side of one end of the transition trough pipe, the lower side of the transition trough pipe is connected to the recovery box, the other end of the transition trough pipe is a slag discharge end, a filter residue conveying assembly with a length and width matching the transition trough pipe is provided below the transition trough pipe, the filter residue conveying assembly includes a filter conveyor belt, the filter conveyor belt is covered with filter holes, the cleaning liquid collection port corresponds to the upper belt surface of the filter conveyor belt, and the upper belt surface can filter the debris in the cleaning liquid and convey it to the slag discharge end.

However, these embodiments are not limited to the present invention, and any structural, methodical, or functional changes made by those of ordinary skill in the art based on these embodiments are included in the protection scope of the present invention.

[0023] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.

[0024] The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0025] As Figures 1 to 7As shown, the present invention discloses a recovery device with liquid separation and self-cleaning functions, including a substrate 1, on which a drain box 2 is fixed. In this preferred embodiment, the top of the drain box 2 is provided with an inlet 21 connected to the liquid outlet of the cleaning machine 100, and the bottom of the drain box 2 is provided with a drain pipe I22 and a drain pipe II23 for discharging the liquid flowing into the inlet 21.

[0026] In the present invention, the liquid discharging box 2 is provided with a liquid discharging assembly 3 for selectively discharging liquid from the liquid discharging pipe I22 or the liquid discharging pipe II23. Specifically, the liquid discharging assembly 3 is at least pivotally arranged on the rotating shaft 35 on the liquid discharging box 2, and a liquid discharging box 31 is fixedly arranged on the rotating shaft 35. An opening I32 is provided on one side of the liquid discharging box 31, and an opening II is provided on the other side. A protruding block 33 integral with the liquid discharging box 31 is provided on the top, and a cover plate 39 is provided on both sides of the protruding block 33. The setting of the cover plate 39 can prevent foreign impurities from falling into the liquid discharging box, thereby ensuring its cleanliness. The protruding block 33 is placed in the inlet 21, and a first liquid inlet 34 is provided on it. A driving motor 36 is fixedly arranged on the liquid discharging box 2, and the motor shaft of the driving motor 36 is connected to the rotating shaft 35 through a reducer 37. The above-mentioned drive motor can control the selective deflection of the liquid separation box 31, so that the cleaning liquid or cutting fluid flowing in from the first liquid inlet 34 can be selectively discharged from the opening I or the opening II. The operation is stable and reliable, and the drive motor has the characteristics of high precision and fast response, which greatly improves the work efficiency. In addition, the arrangement of the liquid separation component 3 realizes the automatic separation of the cleaning liquid and the cutting fluid, realizes high integration, reduces the occupied space, and facilitates reasonable layout.

[0027] However, the above-mentioned liquid separation component 3 will have this problem during the liquid separation process, namely: after the driving motor controls the liquid separation box 31 to deflect, the driving motor will stop working. At this time, the liquid separation box 31 remains in a deflected state, but under the impact of the cleaning fluid or cutting fluid, the liquid separation box 31 may be deflected, and accurate liquid separation of the cleaning fluid or cutting fluid cannot be achieved.

[0028] In view of the above problems, support plates 9 are fixedly provided on the inner walls on both sides of the liquid separation box 31. Guide rails 91 are fixedly provided on the support plates 9. Guide blocks 92 adapted to the guide rails 91 are provided on the guide rails 91.

In the above, the carrying frame 94 can slide on the guide rail 91 under the action of gravity, so that during the liquid separation process, the carrying frame makes the liquid separation box 31 always in an inclined state, which can prevent the liquid separation box 31 from deflecting under the impact force of the cleaning liquid or cutting liquid, and ensure the accuracy of liquid separation.

[0029] In the present invention, the filter screen 95 can perform primary filtration on the cleaning liquid and chip liquid to improve the cleanliness of the cleaning liquid or cutting liquid when it falls into the corresponding slag scraping bin, which is beneficial to subsequent processing. At the same time, the weighing device 93 can weigh the carrying frame 94 in real time. When the preset threshold of the weighing device 93 is exceeded, it reminds to replace the filter screen to avoid the situation that too many impurities on the filter screen 95 affect the use effect. In addition, since the maximum distance between the buffer device 96 and the opening I 32 is less than or equal to the length of the filter screen 95, it is convenient to take out the filter screen 95. This operation is simple and convenient, facilitating quick replacement, and greatly improving work efficiency. The setting of the buffer device 96 can prevent the carrying frame 94 from colliding hard with the liquid separation box 31 and extend the service life.
