[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technology in the embodiments of the present invention, a wear-resistant glass cover suitable for ultrasonic cleaning. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] like Figure 1 - Fig.21As shown, the present invention provides: a wear-resistant glass cover plate suitable for ultrasonic cleaning, including a cover frame 10 hinged to one side of an ultrasonic cleaning machine 60 by a hinge 16. In this embodiment, the storage basket 62 of the ultrasonic cleaning machine 60 is of a lifting type. The lifting mechanism is composed of an oil pump, an oil tank, a hydraulic cylinder and a lifting frame. The storage basket 62 is fixed on the lifting frame. The hydraulic oil at the lower end of the hydraulic cylinder pushes the piston to move upward, thereby driving the lifting frame and the storage basket 62 to rise, and the storage basket 62 is taken out of the cleaning tank 61. When it is necessary to descend, the hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic reversing valve, and the return oil at the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, the hydraulic control one-way valve, the throttle valve and the explosion-proof electromagnetic reversing valve, so that the storage basket 62 descends and is immersed in the cleaning liquid in the cleaning tank 61;

[0052] A viewing window is reserved inside the cover frame 10, and a transparent glass plate 40 is fixed in the viewing window of the cover frame 10, through which the cleaning state of the workpiece in the cleaning tank 61 of the ultrasonic cleaning machine 60 can be conveniently observed, and a first anti-wear curtain 20 and a second anti-wear curtain 30 are respectively rolled up at both ends of the cover frame 10, and an opening and closing linkage mechanism 50 is provided between the first anti-wear curtain 20 and the second anti-wear curtain 30;

[0053] The storage basket 62 of the ultrasonic cleaning machine 60 rises, and the cover frame 10 is supported by the supporting arms 63 symmetrically fixed by the storage basket 62, while the glass plate 40 is flipped upward, and the cleaning tank 61 is opened. During the rising process of the storage basket 62, the second anti-wear curtain 30 is dragged to extend from the cover frame 10 and unfold, and the first anti-wear curtain 20 is synchronously extended from the cover frame 10 and relatively slid and unfolded through the transmission cooperation of the opening and closing linkage mechanism 50. After the unfolded first anti-wear curtain 20 and the second anti-wear curtain 30 are abutted, the glass plate 40 is shielded by the first anti-wear curtain 20 and the second anti-wear curtain 30, and the storage basket 62 is lifted up and separated from the liquid surface of the cleaning tank 61. At this time, when the workpiece in the storage basket 62 is lifted by the lifting equipment, the glass plate 40 is protected by the first anti-wear curtain 20 and the second anti-wear curtain 30 (such as Fig.18 As shown), the sharp part of the workpiece is prevented from directly rubbing against the glass plate 40 to cause wear or direct breakage, so that the overall wear resistance of the glass cover plate is improved and the service life of the glass cover plate is increased;

[0054] The storage basket 62 of the ultrasonic cleaning machine 60 descends, and the cover frame 10 is turned toward the cleaning tank 61 under the action of gravity and covers the cleaning tank 61. When the storage basket 62 descends, the stored workpieces are gradually immersed in the cleaning liquid of the cleaning tank 61. In this process, the cover frame 10 gradually retracts the second anti-wear curtain 30, and the first anti-wear curtain 20 is synchronously retracted into the cover frame 10 under the transmission cooperation of the opening and closing linkage mechanism 50. When the cover frame 10 is attached to the cleaning tank 61, the glass plate 40 area between the first anti-wear curtain 20 and the second anti-wear curtain 30 is not blocked (such as Fig. 20 shown);

[0055] Workers can observe the cleaning status of the workpieces in the cleaning tank 61 through the glass plate 40. At the same time, the glass cover plate shields the cleaning tank 61 to avoid splashing of the cleaning liquid, keep the inside of the cleaning tank 61 clean and hygienic, and reduce the noise generated during the operation of the equipment. Under the premise that the cleaning of the workpiece is visible, the wear or breakage of the glass cover plate by the sharp part of the workpiece is avoided, thereby improving the service life of the glass cover plate.

[0056] like Fig.10 , Fig.14 , Fig.15 As shown, the cover frame 10 includes two parallel side frames 11, a first curtain box 12 is vertically fixed to one end between the two side frames 11, and a second curtain box 13 is vertically fixed to the other end, and the first curtain box 12 and the second curtain box 13 are both provided with strip-shaped through holes 122 on opposite sides thereof;

[0057] The first curtain box 12 is arranged in parallel with the second curtain box 13, and the second curtain box 13 is hinged to one side of the cleaning tank 61 of the ultrasonic cleaning machine 60 through the hinge 16. The first curtain box 12 is used to store the first anti-wear curtain 20, and the second curtain box 13 is used to store the second anti-wear curtain 30. The first anti-wear curtain 20 and the second curtain box 13 are both inserted into the curtain box after passing through the strip through hole 122;

[0058] It is worth noting that in order to prevent the first anti-wear curtain 20 and the second anti-wear curtain 30 from getting stuck at the edge of the strip-shaped through hole 122 during the process of rolling or stretching, the opening edges of the strip-shaped through hole 122 are all chamfered.

[0059] like Figure 4 - Figure 8The first anti-friction curtain 20 includes a plurality of first curtain plates 21, which are hinged in sequence along the length direction by a plurality of hinges 16 (not shown in the figure). The second anti-friction curtain 30 includes a plurality of second curtain plates 31, which are hinged in sequence along the length direction by a plurality of hinges 16 (not shown in the figure). When the first curtain plates 21 and the second curtain plates 31 are extended and placed on one side of the glass plate 40, the plurality of curtain plates at this time form a baffle for shielding the glass plate 40. The hinged connection of the plurality of first curtain plates 21 and the hinged connection of the plurality of second curtain plates 31 facilitates the rolling of the plurality of first curtain plates 21 and the plurality of second curtain plates 31 when rolling up the anti-friction curtain.

[0060] like Figure 7 , Figure 8 Fig.10 , Fig.14 As shown, a first reel 121 for winding a first curtain plate 21 is rotatably connected in the first curtain box 12 through a bearing, and a second reel 131 for winding a second curtain plate 31 is rotatably connected in the second curtain box 13 through a bearing, and the first reel 121 is coaxially arranged with the second reel 131 and the rotating axis of the hinge 16, and the first curtain plate 21 and the second curtain plate 31 of the first anti-friction curtain 20 and the second anti-friction curtain 30 at one end thereof are respectively welded and fixed on the first reel 121 and the second reel 131;

[0061] Both ends of the first reel 121 are connected to the first curtain box 12 by means of a volute spring 15, and both ends of the second reel 131 are connected to the second curtain box 13 by means of a volute spring 15. The inner end of the volute spring 15 is fixed on the reel, and the outer end is fixed on the inner wall of the curtain box. When the first anti-friction curtain 20 is pulled out of the first curtain box 12, the first reel 121 releases the first curtain plate 21 and the volute spring 15 generates a reverse twisting force. At the same time, when the second anti-friction curtain 30 is pulled out of the second curtain box 13, the second reel 131 releases the second curtain plate 31 and the volute spring 15 generates a reverse twisting force.

[0062] When the second anti-wear curtain 30 and the first anti-wear curtain 20 descend in the storage basket 62, the reverse torsional force of the spiral spring 15 drives the first reel 121 to wind and roll up the first anti-wear curtain 20 into the first curtain box 12, and the second reel 131 to wind and roll up the second anti-wear curtain 30 into the second curtain box 13.

[0063] like Figure 7 , Figure 8As shown, a first flexible sheet 22 is fixedly mounted on one side of a plurality of first curtain plates 21, and a second flexible sheet 32 ​​is fixedly mounted on one side of a plurality of second curtain plates 31. The first flexible sheet 22 and the second flexible sheet 32 ​​are made of the same material, both made of silicone material, and are attached to the side of the curtain plate placed on the hinge 16 (that is, the side close to the glass plate 40);

[0064] When the flexible sheet is attached to the surface of the glass plate 40, it can, on the one hand, avoid wear of the glass plate 40 during the rolling process of the hinge 16, the first curtain plate 21, and the second curtain plate 31; on the other hand, the flexible sheet made of silicone can also play a certain buffering role when the first curtain plate 21 and the second curtain plate 31 are impacted on the side away from the flexible sheet. At the same time, the hinge 16 used for the hinged connection of the curtain plate is placed on the inner side of the flexible sheet, and the hinge 16 is protected by the flexible sheet to prevent the hinge 16 from scratching the glass plate 40 when moving.

[0065] like Figure 5 , Figure 7 , Figure 8 As shown, the adjacent first curtain plate 21 and the second curtain plate 31 are respectively hinged with the first pull plate 23 and the second pull plate 33 through the hinge 16, and the opening and closing linkage mechanism 50 includes two fixed pulleys 51, the fixed pulleys 51 are fixed on the side frame 11, and a traction wire rope 52 is wound around the concave wheel of the fixed pulley 51, one end of the traction wire rope 52 is fixed to the first pull plate 23, and the other end is fixed to the second pull plate 33;

[0066] The connecting portion of the traction wire rope 52 placed on the fixed pulley 51 and the second pull plate 33 is the traction portion 521, and the connecting portion of the traction wire rope 52 placed on the fixed pulley 51 and the first pull plate 23 is the pulling portion 522; when the traction portion 521 gradually becomes longer, the pulling portion 522 becomes shorter, and vice versa. Therefore, under the action of the fixed pulley 51, when the second pull plate 33 slides toward the second pull curtain box 13, the second pull plate 33 pulls the first pull plate 23 to slide toward the first pull curtain box 12 through the traction wire rope 52, and the traction portion 521 becomes longer and the pulling portion 522 becomes shorter. At this time, the first anti-wear pull curtain 20 and the second anti-wear pull curtain 30 can be synchronously retracted into the cover frame 10, and the cover frame 10 is covered on the cleaning tank 61 (such as Fig. 20 shown);

[0067] like Figure 8 , Fig.18 , Fig.19 , Fig.21As shown, the second pull plate 33 is symmetrically fixed with a curtain-closing push rod 34, and the supporting arm 63 is close to the second curtain-drawing box 13. The curtain-closing push rod 34 is placed within the axis range of the roller 64 connected to the upper end of the supporting arm 63, and the roller 64 is placed at the side frame 11. When the storage basket 62 rises, the roller 64 at the upper end of the supporting arm 63 pushes the side frame 11 to flip upward with the connecting axis of the hinge 16 as the axis center, and when the roller 64 hits the curtain-closing push rod 34, the curtain-closing push rod 34 drives the second pull plate 33 to push in the direction of the first pull plate 23. Under the action of the fixed pulley 51 and the traction wire rope 52, the first pull plate 23 and the second pull plate 33 slide relative to each other, and at the same time, the spiral spring 15 generates a reverse torsional force, and when the first pull plate 23 and the second pull plate 33 hit each other, the cover frame 10 is now flipped over, and the storage basket 62 is separated from the cleaning liquid in the cleaning tank 61 (as shown in FIG. Fig.18 as shown).

[0068] like Fig.14 , Fig.16 , Fig.17 As shown, slideways 112 are provided on opposite sides of the two side frames 11, and the slideways 112 are connected to the strip-shaped through holes 122. The first curtain plate 21 and the second curtain plate 31 slide in contact with the inner wall of the slideway 112, and the slideway 112 guides the sliding of the first curtain plate 21 and the second curtain plate 31. Under the action of the slideway 112, a certain distance can be maintained between the first curtain plate 21 and the second curtain plate 31 and the glass plate 40, so that a buffer zone can be formed when the workpiece collides with the curtain plate.

[0069] like Fig.10 , Fig.17 As shown, the side frame 11 is provided with a traction cavity 111, which is connected to the slideway 112, and the fixed pulley 51 is fixed in the traction cavity 111. Firstly, it increases the overall aesthetics, and secondly, it avoids the problem of the traction wire rope 52 falling off from the fixed pulley 51 due to the insertion of other objects exposed to the outside of the side frame 11.

[0070] like Fig.21 As shown, when the glass cover is flipped open, in order to make the cover frame 10 close to the roller 64 at the upper end of the supporting arm 63, a supporting spring piece 18 is fixed on the side of the second curtain box 13 away from the side frame 11, and at the same time, the side of the supporting spring piece 18 away from the second curtain box 13 is an arc structure. When the cover frame 10 is flipped around the connecting axis of the hinge 16 and the supporting spring piece 18 is pressed on the ultrasonic cleaning machine 60, the supporting spring piece 18 is elastically bent and generates a reverse elastic rebound force. Therefore, when the storage basket 62 descends, the glass cover can be assisted to flip toward the cleaning tank 61 under the elastic rebound action of the supporting spring piece 18.

[0071] like Fig.19As shown, by symmetrically fixing the limit block 17 on one side of the side frame 11 away from the glass plate 40, when the roller 64 pushes the curtain-closing push rod 34 upward (close to the end of the first curtain-pulling box 12), the limit block 17 is placed at the sliding path of the curtain-closing push rod 34, and when the curtain-closing push rod 34 abuts against the limit block 17, the first pull plate 23 abuts against the second pull plate 33, the glass cover plate flips upward, and the storage basket 62 is separated from the cleaning liquid in the cleaning tank 61, thereby preventing the curtain-closing push rod 34 from being excessively pushed upward, and playing a role in limiting the curtain-closing push rod 34;

[0072] like Figure 3 As shown, a sealing ring 14 is fixed to one side of the cover frame 10 close to the limit block 17 . When the cover frame 10 is turned toward the cleaning tank 61 and attached to the ultrasonic cleaning machine 60 , the sealing ring 14 can improve the sealing effect of the glass cover plate around the cleaning tank 61 .

[0073] like Figure 5 , Fig.16 , Fig.17 As shown, a guide rod 113 is fixed to one side of the inner wall of the slide 112 close to the curtain closing push rod 34, and both ends of the guide rod 113 (that is, one end placed on the first curtain box 12 and the second curtain box 13) are rounded chamfers, and the first curtain plate 21 and the second curtain plate 31 are both provided with a limiting slide groove 24 adapted to the guide rod 113. Therefore, when the first curtain plate 21 and the second curtain plate 31 slide from the curtain box into the strip through hole 122, the guide rod 113 and the limiting slide groove 24 are convenient to cooperate. Through the cooperation between the limiting slide grooves 24 of the first curtain plate 21 and the second curtain plate 31 and the guide rod 113, when the first curtain plate 21 and the second curtain plate 31 are impacted from the outside, the cooperation between the guide rod 113 and the limiting slide groove 24 can prevent the first curtain plate 21 and the second curtain plate 31 from bending and hitting the glass plate 40.

[0074] like Figure 6 , Figure 7 , Figure 8 , Fig. 20 As shown, a wiper strip 25 is fixed to one side of the first pull plate 23 and the second pull plate 33 close to the glass plate 40, and the wiper strip 25 is in contact with the glass plate 40. When the first pull plate 23 and the second pull plate 33 slide along the side frame 11, the wiper strip 25 is in contact with the side of the glass plate 40 close to the cleaning tank 61 and slides. Then, when the first pull plate 23 and the second pull plate 33 slide, the inner side of the glass plate 40 can be wiped and cleaned by the wiper strip 25. When the cover frame 10 is flipped upward, the water stains on the inner side of the glass plate 40 flow into the second curtain box 13 along the surface through the strip through holes 122, and finally are discharged through a plurality of drainage holes 132 provided on the side of the second curtain box 13 close to the hinge 16, thereby avoiding water accumulation in the second curtain box 13.

[0075] Working principle:

[0076] by Fig. 20 For example, the cover frame 10 is covered on the cleaning tank 61, at this time, the curtain closing push rod 34 is against the side of the strip through hole 122 of the second curtain box 13, and at the same time, the first anti-wear curtain 20 is wound counterclockwise around the first reel 121 in the first curtain box 12, and the second anti-wear curtain 30 is wound clockwise around the second reel 131 in the second curtain box 13, and the supporting arm 63 and the roller 64 are placed between the curtain closing push rod 34 and the second curtain box 13 (as shown in FIG. Fig.21 As shown), the glass plate 40 is in a visible state at this time, and the cleaning condition of the workpiece in the cleaning tank 61 can be observed through the glass plate 40.

[0077] After cleaning is completed, the storage basket 62 is driven to rise by the lifting frame, and when the roller 64 abuts against the side frame 11, the cover frame 10 is turned counterclockwise around the connecting axis of the hinge 16 (such as Fig.21 As shown in the figure, when the roller 64 abuts against the curtain closing push rod 34, in the process of the supporting arm 63 gradually rising, the roller 64 pushes the curtain closing push rod 34 to slide upward along the slideway 112, and through the cooperation between the traction wire rope 52 and the fixed pulley 51, the traction part 521 gradually becomes shorter, and the pulling part 522 gradually becomes longer, and the first pull plate 23 and the second pull plate 33 slide relative to each other through the traction of the traction wire rope 52;

[0078] During the relative sliding of the first pull plate 23 and the second pull plate 33, the first pull plate 23 pulls the first reel 121 to rotate in the clockwise direction, and the spiral spring 15 generates a torsional force driving the first reel 121 in the counterclockwise direction, and the plurality of first curtain plates 21 are released from the first reel 121. Meanwhile, the second pull plate 33 pulls the second reel 131 to rotate in the counterclockwise direction, and the spiral spring 15 generates a torsional force driving the second reel 131 in the clockwise direction, and the plurality of second curtain plates 31 are released from the second reel 131.

[0079] When the curtain closing push rod 34 abuts against the limit block 17, the storage basket 62 completes the lifting action and is separated from the cleaning liquid. At the same time, the first pull plate 23 and the second pull plate 33 abut against each other, and the multiple first curtain plates 21 and the second curtain plates 31 between the first curtain pulling box 12 and the second curtain pulling box 13 protect the glass plate 40 close to the cleaning tank 61. The workpiece in the storage basket 62 after cleaning can be removed by a single-arm crane. When the workpiece collides with the glass plate 40 due to improper operation by the staff, the glass plate 40 can be protected by the first curtain plate 21 and / or the second curtain plate 31, thereby increasing the wear resistance of the glass cover plate and avoiding it from being broken.

[0080] The next workpiece to be cleaned is hoisted into the storage basket 62, and then the lifting frame drives the storage basket 62 to descend in the cleaning tank 61. Subsequently, under the reverse rebound force of the supporting spring 18, the cover frame 10 is turned over in the clockwise direction with the connecting axis of the hinge 16. When the height of the roller 64 gradually decreases, the spiral springs 15 at both ends of the first reel 121 are twisted, so that the first reel 121 is counterclockwise wound around the first curtain plate 21, and the spiral springs 15 at both ends of the second reel 131 are twisted, so that the second reel 131 is clockwise wound around the second curtain plate 31 (as shown in FIG. 1 ). Fig.14 As shown), when the cover frame 10 abuts against the edge of the cleaning tank 61, the area between the first pull plate 23 and the second pull plate 33 is open, and the open area of ​​the glass plate 40 is not blocked (as shown). Fig. 20 , Fig.21 As shown in the figure), the worker can observe the situation in the cleaning tank 61 through the transparent glass plate 40, and repeat the above steps for the next workpiece after cleaning is completed.
