Description

Technical Field

[0001] The present invention relates to the technical field of glass covers, and particularly to a wear-resistant glass cover suitable for ultrasonic cleaning. Background Art

[0002] The glass cover plays an important role in shielding the cleaning tank of an ultrasonic cleaning machine. The glass cover can shield the opening part of the cleaning tank, effectively preventing the splashing of the cleaning liquid caused by liquid vibration and bubble rupture during ultrasonic cleaning; preventing external sundries and dust from entering the inside of the cleaning tank, keeping the inside of the cleaning tank clean and hygienic; and effectively isolating the noise generated during the operation of the ultrasonic cleaning machine, reducing the impact of the noise on the operator and the surrounding environment; at the same time, the glass cover can also solve the problem that the traditional stainless steel cover does not allow the operator to clearly observe the inside of the cleaning tank.

[0003] However, during the use of the glass cover, especially when a relatively large workpiece needs to be lifted into the cleaning tank by a hoisting device, during the suspension and removal of the workpiece in the cleaning tank, the workpiece will swing in the air. During the swinging process of the workpiece, due to improper operation by the worker, it is very easy for the workpiece to rub against the glass cover. In the light case, a large number of scratches will appear on the surface of the glass cover, affecting the clarity of the glass cover. In the heavy case, the glass cover will be directly broken, reducing its service life. Summary of the Invention

[0004] The purpose of the present invention is to propose a wear-resistant glass cover suitable for ultrasonic cleaning to solve the problem that during the swinging of the workpiece, due to improper operation by the worker, the workpiece rubs against the glass cover, causing glass wear or damage.

[0005] To achieve the above purpose, the present invention adopts the following technical solution: A wear-resistant glass cover suitable for ultrasonic cleaning, including a cover frame hinged to one side of the ultrasonic cleaning machine, and a transparent glass plate is fixed inside the cover frame; first anti-wear draw curtains and second anti-wear draw curtains are respectively wound at both ends of the cover frame, and an opening and closing linkage mechanism is in transmission cooperation between the first anti-wear draw curtain and the second anti-wear draw curtain;

[0006] The cover frame is supported and flipped by the storage basket of the ultrasonic cleaning machine, and the second anti-wear draw curtain is dragged to unfold. The first anti-wear draw curtain is synchronously and relatively unfolded through the transmission cooperation of the opening and closing linkage mechanism. After unfolding, the first anti-wear draw curtain and the second anti-wear draw curtain shield the glass plate;

[0007] The storage basket of the ultrasonic cleaning machine descends, the cover frame is flipped and closed, the cover frame winds up the second anti-wear draw curtain, and the first anti-wear draw curtain is synchronously wound up through the transmission cooperation of the opening and closing linkage mechanism, and the glass plate is unshielded.

[0008] As a further description of a wear-resistant glass cover plate applicable to ultrasonic cleaning in the above technology: The cover frame includes two parallel side frames. At both ends of the side frames, a first curtain box and a second curtain box are respectively fixed. Strip-shaped through holes are formed on the opposite sides of the first curtain box and the second curtain box.

[0009] The first anti-wear curtain includes multiple first curtain plates, which are successively hinged between the multiple first curtain plates. The second anti-wear curtain includes multiple second curtain plates, which are successively hinged between the multiple second curtain plates.

[0010] A first reel for winding the first curtain plate is rotatably connected in the first curtain box through a bearing. A second reel for winding the second curtain plate is rotatably connected in the second curtain box through a bearing. The first reel is elastically torsionally connected in the first curtain box, and the second reel is elastically torsionally connected in the second curtain box.

A second flexible thin sheet is fixedly installed on one side of the multiple second curtain plates.

[0012] As a further description of a wear-resistant glass cover plate applicable to ultrasonic cleaning in the above technology: The adjacent first curtain plate and second curtain plate are respectively hinged with a first pull plate and a second pull plate through hinges. The opening and closing linkage mechanism includes two fixed pulleys, which are fixed on the side frame. A traction steel wire rope is wound around the concave wheel of the fixed pulley. One end of the traction steel wire rope is fixed to the first pull plate, and the other end is fixed to the second pull plate.

[0013] The second pull plate is symmetrically fixed with a curtain closing push rod.

[0014] As a further description of a wear-resistant glass cover plate applicable to ultrasonic cleaning in the above technology: Slideways are formed on the opposite sides of the two side frames. The side frame is provided with a traction cavity communicating with the slideway. The fixed pulley and the traction steel wire rope are placed in the traction cavity.

[0015] As a further description of a wear-resistant glass cover plate applicable to ultrasonic cleaning in the above technology: A support elastic sheet is fixed on the side of the second curtain box away from the side frame.

[0016] As a further description of a wear-resistant glass cover plate applicable to ultrasonic cleaning in the above technology: The side frame is symmetrically fixed with limit blocks. A sealing ring is fixed on the side of the cover frame close to the limit blocks.

[0017] As a further description of a wear-resistant glass cover plate applicable to ultrasonic cleaning in the above technology: A guide rod is fixed on one side of the inner wall of the slideway close to the curtain closing push rod. Limit sliding grooves adapted to the guide rod are formed on both the first curtain plate and the second curtain plate.

[0019] In summary, due to adopting the above technology of a wear-resistant glass cover plate suitable for ultrasonic cleaning, the beneficial effects of the present invention are as follows:

[0020] 1. When the glass cover plate in the present application is turned upwards, the first anti-wear curtain and the second anti-wear curtain can be unfolded in opposite directions to protect the glass plate in the glass cover plate, preventing the problem that the sharp part directly rubs against the glass plate or directly breaks due to improper operation of the worker during the lifting of the workpiece; when the glass cover plate is turned towards the cleaning tank, the first anti-wear curtain box and the second anti-wear curtain are wound into the cover frame, and the glass plate area between the first anti-wear curtain and the second anti-wear curtain is unobstructed. Workers can observe the cleaning situation of the workpiece in the cleaning tank through the glass plate. By blocking the cleaning tank with the glass cover plate, the phenomenon of cleaning liquid splashing is avoided, the cleanliness and hygiene inside the cleaning tank are maintained, and the noise generated during the operation of the equipment is reduced; on the premise that the workpiece cleaning is visible, the wear or breakage of the glass cover plate by the sharp part of the workpiece is avoided, and the service life of the glass cover plate is improved.

[0021] 2. By fixing wiper strips on the inner sides of the first pull plate and the second pull plate and opening a plurality of drain holes at the bottom of the second curtain box, the wiper strips can wipe and clean the inner side of the glass plate when the cover frame is turned upwards. The water stains flow along the surface through the strip-shaped through holes into the second curtain box, and finally are discharged through the plurality of drain holes formed on one side of the second curtain box close to the hinge, thereby avoiding water accumulation in the second curtain box.

[0049] 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.

[0050] like Figure 1 - Figure 20As 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 a lifting type, and the lifting mechanism is composed of an oil pump, an oil tank, a hydraulic cylinder and a lifting frame part. The storage basket 62 is fixed on the lifting frame. The hydraulic oil at the lower end of the hydraulic cylinder pushes the piston upward, thereby driving the lifting frame and the storage basket 62 to rise, and the storage basket 62 is taken out from the cleaning tank 61. When it needs to descend, the hydraulic oil enters the upper end of the hydraulic cylinder through an explosion-proof electromagnetic directional valve, and the oil return at the lower end of the hydraulic cylinder returns to the oil tank through a balance valve, a pilot-operated check valve, a throttle valve and an explosion-proof electromagnetic directional valve, so that the storage basket 62 descends and immerses in the cleaning liquid in the cleaning tank 61;

[0051] A window is reserved inside the cover frame 10, and a transparent glass plate 40 is fixed in the window of the cover frame 10. Through the transparent glass plate 40, it is convenient to observe the cleaning state of the workpiece in the cleaning tank 61 of the ultrasonic cleaning machine 60. First anti-wear pull curtains 20 and second anti-wear pull curtains 30 are respectively wound at both ends of the cover frame 10, and an opening and closing linkage mechanism 50 is in transmission cooperation between the first anti-wear pull curtain 20 and the second anti-wear pull curtain 30;

[0052] When the storage basket 62 of the ultrasonic cleaning machine 60 rises, the cover frame 10 is supported by the support arms 63 symmetrically fixed to the storage basket 62, and at the same time, the glass plate 40 is driven to turn upward, and the cleaning tank 61 is opened. During the rising process of the storage basket 62, the second anti-wear pull curtain 30 is dragged out and unfolded from the cover frame 10, and the first anti-wear pull curtain 20 is synchronously extended and relatively slid and unfolded from the cover frame 10 through the transmission cooperation of the opening and closing linkage mechanism 50. After the unfolded first anti-wear pull curtain 20 and the second anti-wear pull curtain 30 are abutted, at this time, the glass plate 40 is blocked by the first anti-wear pull curtain 20 and the second anti-wear pull curtain 30. When the storage basket 62 is lifted out of the liquid level of the cleaning tank 61, when the workpiece in the storage basket 62 is lifted by a hoisting device at this time, at this time, the glass plate 40 is protected by the first anti-wear pull curtain 20 and the second anti-wear pull curtain 30 (as Figure 18 shown), preventing the problem of wear or direct breakage caused by the sharp part of the workpiece directly rubbing against the glass plate 40, improving the overall wear-resistant performance of the glass cover plate and increasing the service life of the glass cover plate;

[0053] The storage wire basket 62 of the ultrasonic cleaning machine 60 descends, and the cover frame 10 flips towards the cleaning tank 61 under the action of gravity and covers above the cleaning tank 61. During the process of the storage wire basket 62 descending, the stored workpieces are gradually immersed in the cleaning liquid in the cleaning tank 61. And during this process, the cover frame 10 gradually winds up the second anti-abrasion curtain 30, and the first anti-abrasion curtain 20 is synchronously wound into the cover frame 10 through the transmission and cooperation of the opening and closing linkage mechanism 50. When the cover frame 10 fits with the cleaning tank 61, there is no obstruction in the glass plate 40 area between the first anti-abrasion curtain 20 and the second anti-abrasion curtain 30 at this time;

[0054] Workers can observe the cleaning situation of the workpieces in the cleaning tank 61 through the glass plate 40. At the same time, due to the shielding of the cleaning tank 61 by the glass cover plate, the phenomenon of cleaning liquid splashing is avoided, the cleanliness and hygiene inside the cleaning tank 61 are maintained, and the noise generated during the operation of the equipment is reduced; on the premise that the workpiece cleaning is visible, the wear or breakage of the glass cover plate by the sharp parts of the workpiece is avoided, and the service life of the glass cover plate is improved.

[0055] As Figure 10 、 Figure 14 、 Figure 15 As shown, the cover frame 10 includes two parallel side frames 11. At one end between the two side frames 11, a first curtain box 12 is vertically fixed, and at the other end, a second curtain box 13 is vertically fixed. Bar-shaped through holes 122 are opened on the opposite sides of the first curtain box 12 and the second curtain box 13;

[0056] The first curtain box 12 and the second curtain box 13 are arranged in parallel, and the second curtain box 13 is hinged to one side of the cleaning tank 61 of the ultrasonic cleaning machine 60 through a hinge 16. The first curtain box 12 is used to store the first anti-abrasion curtain 20, and the second curtain box 13 is used to store the second anti-abrasion curtain 30. Both the first anti-abrasion curtain 20 and the second anti-abrasion curtain 30 pass through the bar-shaped through holes 122 and then penetrate into the curtain box;

[0057] It should be noted that in order to prevent the first anti-abrasion curtain 20 and the second anti-abrasion curtain 30 from getting stuck at the edge of the bar-shaped through hole 122 during the winding or stretching process, the opening edges of the bar-shaped through holes 122 are all round chamfers.

[0058] As Figure 4 - Figure 8, the first anti-wear pull curtain 20 includes multiple first curtain plates 21, and the multiple first curtain plates 21 are sequentially hinged along the length direction through a plurality of hinges 16 (not shown in the figure). The second anti-wear pull curtain 30 includes multiple second curtain plates 31, and the multiple second curtain plates 31 are sequentially hinged along the length direction through a plurality of hinges 16 (not shown in the figure). When the first curtain plate 21 and the second curtain plate 31 are extended and placed on one side of the glass plate 40, the multiple curtain plates at this time form a baffle for blocking the glass plate 40. Through the hinging of the multiple first curtain plates 21 and the hinging of the multiple second curtain plates 31, when the anti-wear pull curtain is wound up, it is convenient to wind up the multiple first curtain plates 21 and the multiple second curtain plates 31;

[0059] As Figure 7 , Figure 8 Figure 10 , Figure 14 As shown, a first reel 121 for winding the first curtain plate 21 is rotatably connected in the first curtain box 12 through a bearing, and a second reel 131 for winding the second curtain plate 31 is rotatably connected in the second curtain box 13 through a bearing. The first reel 121, the second reel 131, and the rotating shaft of the hinge 16 are coaxially arranged. The first curtain plates 21 and the second curtain plates 31 at the separated ends of the first anti-wear pull curtain 20 and the second anti-wear pull curtain 30 are respectively welded and fixed on the first reel 121 and the second reel 131;

[0060] Both ends of the first reel 121 are elastically torsionally connected in the first curtain box 12 through a volute spring 15. Both ends of the second reel 131 are elastically torsionally connected in the second curtain box 13 through 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-wear pull curtain 20 is pulled out from the first curtain box 12, the first reel 121 releases the first curtain plate 21 and the volute spring 15 generates a reverse torsional force. At the same time, when the second anti-wear pull curtain 30 is pulled out from the second curtain box 13, the second reel 131 releases the second curtain plate 31 and the volute spring 15 generates a reverse torsional force;

[0061] When the second anti-wear pull curtain 30 and the first anti-wear pull curtain 20 are lowered when the storage wire basket 62 is lowered, under the reverse torsional force of the volute spring 15, the first reel 121 is driven to wind up the first anti-wear pull curtain 20 into the first curtain box 12, and the second reel 131 winds up the second anti-wear pull curtain 30 into the second curtain box 13.

[0062] As Figure 7 , Figure 8As shown, a first flexible sheet 22 is fixedly installed on one side of multiple first curtain plates 21, and a second flexible sheet 32 is fixedly installed on one side of multiple 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 pasted on one side of the curtain plate where the hinge 16 is located (that is, the side close to the glass plate 40);

[0063] When the flexible sheet fits on the surface of the glass plate 40, first, it avoids the wear of the glass plate 40 during the winding process of the hinge 16, the first curtain plate 21, and the second curtain plate 31. Second, through the flexible sheet made of silicone, when the sides of the first curtain plate 21 and the second curtain plate 31 away from the flexible sheet are impacted, the flexible sheet can also play a certain buffering role. At the same time, the hinge 16 for curtain plate hinging is placed inside the flexible sheet, and the flexible sheet is used to protect the hinge 16 to prevent the hinge 16 from scratching the glass plate 40 when moving.

[0064] As Figure 5 、 Figure 7 、 Figure 8 As shown, the adjacent first curtain plate 21 and second curtain plate 31 are respectively hinged with a first pull plate 23 and a second pull plate 33 through a hinge 16. The opening and closing linkage mechanism 50 includes two fixed pulleys 51. The fixed pulleys 51 are fixed on the side frame 11. A traction steel wire rope 52 is wound around the concave wheel of the fixed pulley 51. One end of the traction steel wire rope 52 is fixed to the first pull plate 23, and the other end is fixed to the second pull plate 33;

[0065] The part of the traction steel wire rope 52 between the fixed pulley 51 and the second pull plate 33 is the traction part 521, and the part of the traction steel wire rope 52 between the fixed pulley 51 and the first pull plate 23 is the pulling part 522; when the traction part 521 gradually becomes longer, the pulling part 522 becomes shorter, and vice versa. Therefore, under the action of the fixed pulley 51, when the second pull plate 33 slides towards the second curtain box 13, at this time, the second pull plate 33 pulls the first pull plate 23 to slide towards the first curtain box 12 through the traction steel wire rope 52, and the traction part 521 becomes longer and the pulling part 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;

[0066] As Figure 8 、 Figure 18 、 Figure 19 、 Figure 20As shown in the figure, the second pull plate 33 is symmetrically fixed with a curtain-closing push rod 34. The support arm 63 is close to the second curtain box 13. The curtain-closing push rod 34 is within the axis range of the roller 64 rotatably connected to the upper end of the support 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 support arm 63 pushes the side frame 11 to turn upward with the connecting shaft of the hinge 16 as the axis. And when the roller 64 abuts against the curtain-closing push rod 34, at this time, 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 steel wire rope 52, the first pull plate 23 and the second pull plate 33 slide relative to each other. At the same time, the scroll spring 15 generates a reverse torsional force. And when the first pull plate 23 and the second pull plate 33 abut against each other, at this time, the cover frame 10 completes the flip, and at the same time, the storage basket 62 is separated from the cleaning liquid in the cleaning tank 61 (such as Figure 18 shown).

[0067] As Figure 14 , Figure 16 , Figure 17 shown, slideways 112 are provided on the relative sides of the two side frames 11. The slideways 112 are communicated with the strip-shaped through holes 122. The first curtain plate 21 and the second curtain plate 31 are in sliding fit with the inner walls of the slideways 112, and the sliding of the first curtain plate 21 and the second curtain plate 31 is guided by the slideways 112. Under the action of the slideways 112, the first curtain plate 21 and the second curtain plate 31 can be kept at a certain distance from the glass plate 40. Therefore, when a workpiece collides with the curtain plate, a buffer zone can be formed;

[0068] As Figure 10 , Figure 17 shown, the side frame 11 is provided with a traction cavity 111. The traction cavity 111 is communicated with the slideway 112. The fixed pulley 51 is fixed in the traction cavity 111. One is to increase the overall aesthetics, and the other is to avoid the problem that the traction steel wire rope 52 falls off the fixed pulley 51 caused by other objects inserted outside the side frame 11.

[0069] As Figure 18 shown, when the glass cover plate is in the flipped-open state, in order to make the cover frame 10 closely adhere to the roller 64 at the upper end of the support arm 63, a support elastic piece 18 is fixed on the side of the second curtain box 13 away from the side frame 11. At the same time, the side of the support elastic piece 18 away from the second curtain box 13 is an arc structure. When the cover frame 10 turns with the connecting shaft of the hinge 16 as the axis and the support elastic piece 18 is pressed against the ultrasonic cleaning machine 60, at this time, the support elastic piece 18 is elastically bent and generates a reverse elastic rebound force. Therefore, when the storage basket 62 descends, under the elastic rebound action of the support elastic piece 18, it can assist the glass cover plate to turn towards the cleaning tank 61.

[0070] As Figure 19As shown in the figure, by symmetrically fixing the limit blocks 17 on the side of the side frame 11 away from the glass plate 40, when the roller 64 pushes the curtain closing push rod 34 upward (towards the end close to the first curtain pulling box 12), the limit blocks 17 are placed on the sliding path of the curtain closing push rod 34. After the curtain closing push rod 34 abuts against the limit blocks 17, at this time the first pulling plate 23 abuts against the second pulling plate 33, and the glass cover plate flips upward, and the storage wire basket 62 is separated from the cleaning liquid in the cleaning tank 61, thereby avoiding excessive upward pushing of the curtain closing push rod 34 and playing a role in limiting the curtain closing push rod 34;

[0071] As Figure 3 shown, a sealing ring 14 is fixed on the side of the cover frame 10 close to the limit block 17. When the cover frame 10 flips towards the cleaning tank 61 and adheres to the ultrasonic cleaner 60, the sealing ring 14 can improve the sealing effect of the glass cover plate around the cleaning tank 61.

[0072] As Figure 5 、 Figure 16 、 Figure 17 shown, a guide rod 113 is fixed on the inner wall of the slideway 112 close to the curtain closing push rod 34. At the same time, both ends of the guide rod 113 (that is, the ends placed in the first curtain pulling box 12 and the second curtain pulling box 13) are round chamfers. The first curtain plate 21 and the second curtain plate 31 are both provided with limit sliding grooves 24 adapted to the guide rod 113. Therefore, when the first curtain plate 21 and the second curtain plate 31 slide from the curtain pulling box into the strip-shaped through hole 122, it is convenient for the cooperation between the guide rod 113 and the limit sliding groove 24. Through the cooperation between the limit sliding 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 externally, at this time through the cooperation between the guide rod 113 and the limit sliding groove 24, the first curtain plate 21 and the second curtain plate 31 can be prevented from bending and hitting the glass plate 40.

[0073] As Figure 6 、 Figure 7 、 Figure 8 shown, a wiper strip 25 is fixed on the side of the first pulling plate 23 and the second pulling plate 33 close to the glass plate 40. The wiper strip 25 is attached to the glass plate 40. When the first pulling plate 23 and the second pulling plate 33 slide along the side frame 11, the wiper strip 25 slides while adhering to the side of the glass plate 40 close to the cleaning tank 61. Therefore, when the first pulling plate 23 and the second pulling plate 33 slide, at this time the wiper strip 25 can scrape and clean the inner side of the glass plate 40. When the cover frame 10 flips upward, the water stains on the inner side of the glass plate 40 flow into the second curtain pulling box 13 along the surface through the strip-shaped through hole 122, and finally are discharged through a plurality of drain holes 132 opened on the side of the second curtain pulling box 13 close to the hinge 16, thereby avoiding water accumulation in the second curtain pulling box 13.

[0074] Working principle:

[0075] Taking the case where the cover frame 10 covers the cleaning tank 61 as an example, at this time, the curtain closing push rod 34 abuts against the side of the strip-shaped through hole 122 of the second curtain pulling box 13. At the same time, the first anti-wear curtain 20 is wound and retracted counterclockwise on the first reel 121 in the first curtain pulling box 12, and the second anti-wear curtain 30 is wound and retracted clockwise on the second reel 131 in the second curtain pulling box 13. The support boom 63 and the roller 64 are placed between the curtain closing push rod 34 and the second curtain pulling box 13 (as Figure 20 shown). At this time, the glass plate 40 is in a visible state, and the cleaning condition of the workpiece in the cleaning tank 61 can be observed through the glass plate 40.

[0076] After the cleaning is completed, the storage wire basket 62 is driven to rise by the lifting frame. When the roller 64 abuts against the side frame 11, the cover frame 10 rotates counterclockwise around the connecting shaft of the hinge 16 (as Figure 20 shown). After the roller 64 abuts against the curtain closing push rod 34, during the process of the gradual rising of the support boom 63, the roller 64 pushes the curtain closing push rod 34 to slide upward along the slideway 112. And through the cooperation of the traction steel wire rope 52 and the fixed pulley 51, the traction part 521 gradually becomes shorter, and the pulling part 522 gradually becomes longer. Driven by the traction of the traction steel wire rope 52, the first pull plate 23 and the second pull plate 33 slide relatively;

[0077] 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 clockwise, and the volute spring 15 generates a torsional force that drives the first reel 121 to rotate counterclockwise, and multiple first curtain plates 21 are released from the first reel 121. At the same time, the second pull plate 33 pulls the second reel 131 to rotate counterclockwise, and the volute spring 15 generates a torsional force that drives the second reel 131 to rotate clockwise, and multiple second curtain plates 31 are released from the second reel 131;

[0078] After the curtain closing push rod 34 abuts against the limit block 17, the storage wire basket 62 completes the lifting action at this time 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. Multiple first curtain plates 21 and second curtain plates 31 between the first curtain pulling box 12 and the second curtain pulling box 13 protect the glass plate 40 on the side close to the cleaning tank 61. The workpiece that has been cleaned in the storage wire basket 62 can be taken down by a single-arm crane. When the workpiece collides with the glass plate 40 due to improper operation by the staff, at this time, the first curtain plate 21 and / or the second curtain plate 31 can protect the glass plate 40, thereby increasing the wear resistance of the glass cover plate and preventing it from being broken by collision.

[0079] Lift the next workpiece to be cleaned and hoist it into the storage wire basket 62. Then, the lifting frame drives the storage wire basket 62 to descend in the cleaning tank 61. Subsequently, under the reverse spring-back force of the support spring piece 18, the cover frame 10 rotates clockwise around the connecting shaft of the hinge 16. And when the height of the roller 64 gradually decreases, due to the torsional action of the torsion springs 15 at both ends of the first reel 121, the first reel 121 winds the first curtain plate 21 counterclockwise, while the torsion springs 15 at both ends of the second reel 131 cause the second reel 131 to wind the second curtain plate 31 clockwise (as Figure 14 shown). And 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. At this time, the open area of the glass plate 40 is unobstructed, and the worker can observe the situation inside the cleaning tank 61 through the transparent glass plate 40. After the cleaning is completed, repeat the above steps for the next workpiece cleaning.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
