Description

Technical Field

[0001] The invention relates to the technical field of screen glass production and processing, and in particular to an ultrasonic cleaning rotating rack. Background Art

[0002] In recent years, with the continuous development of the electronic information industry, the use of display devices has become more and more extensive. The screen is one of the important components of the display device. There is a layer of glass in the screen. When the glass is produced in the factory, large pieces of glass will be placed in the CNC processing equipment for cutting and processing, and then the processed glass will be transferred to the ultrasonic cleaning machine for cleaning, and then the cleaned glass will be taken out for coating, lamination and other processes.

[0003] After CNC processing and cutting, large quantities of glass need to be transported. It is laborious to transport them one by one manually, and the glass is easily scratched during the transportation process, which reduces the yield rate and affects production efficiency.

[0004] A Chinese patent with authorization announcement number CN206345453U discloses a transport rack for mobile phone screen glass, including at least two parallel side panels and a support part for clamping the mobile phone screen glass, the side panels are provided with a plurality of through holes for installing the support part, and the side panels are provided with three layers of horizontally arranged waist-shaped holes, each layer of waist-shaped holes is arranged in parallel, and three waist-shaped holes are arranged at the same horizontal height.

[0005] In the above scheme, side panels are arranged in parallel, support rods are arranged between the side panels, and grooves for placing mobile phone screens are arranged on the support rods, so that the mobile phone screen glass can be effectively fixed, and the contact area between the mobile phone screen glass and the support rods is small, and its side wall is in contact with the support rods, which effectively prevents the mobile phone screen glass from being scratched; however, the waist-shaped holes are used in the above scheme, which makes it more troublesome to adjust when clamping and fixing the glass, and often both sides need to be adjusted at the same time, and the adjustment needs to be repeated many times to clamp the glass, which is more troublesome. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention provides an ultrasonic cleaning rotating rack to solve the problem that the glass surface may be scratched during the transportation process, thereby affecting the glass yield.

[0007] In order to solve the above problems, the technical solution adopted by the present invention is:

[0008] An ultrasonic cleaning rotating frame comprises two parallel side plates, the ends of the two side plates are connected by a fixing rod, a first clamping plate and a second clamping plate for clamping glass are transversely installed between the two side plates, both ends of the first clamping plate and the second clamping plate are screw-shaped, plastic racks are fixed to the opposite sides of the first clamping plate and the second clamping plate, a transverse sliding groove is opened at the upper rear part of the two side plates, the two ends of the first clamping plate are placed in the sliding groove, a plurality of positioning through holes are opened at the upper front part of the two side plates, the two ends of the second clamping plate are placed in the through holes, a waist-shaped groove is opened transversely in the middle part below the first clamping plate and the second clamping plate installed on the two side plates, and the two ends of the third clamping plate are clamped in the waist-shaped groove.

[0009] The principle of this solution is as follows: by using two side plates connected by fixing rods and placing glass inside the side plates, the glass can be transported, and more glass can be transported at one time, while avoiding scratches on the glass; when clamping the glass, the size of the glass is preliminarily determined, and the second clamping plate is placed in a suitable positioning through hole, and the glass is then placed between the first clamping plate and the second clamping plate. After the placement is completed, the initial clamping of the glass is completed, and then the first clamping plate is moved through the slide groove to achieve secondary fixation of the glass. It is convenient to move the first clamping plate, so that when the clamping plate is clamped and fixed, there is no need for the two clamping plates to move at the same time to clamp the glass, which reduces the glass clamping process and improves the efficiency of glass transportation.

[0010] The beneficial effects of this program are:

[0011] Compared with the prior art in which waist-shaped grooves are provided on the surfaces of the side panels, since there is no connecting rod to fix the two side panels, when it is necessary to adjust according to the size of the glass, multiple support rods for clamping the glass need to be moved to adapt to the size of the glass as much as possible. The side panels on both sides are unstable when moving, which is more troublesome. At the same time, when the glass is moving, it is necessary to manually hold the glass steady by hand. Once the glass falls, it is easy to cause scratches on the glass. In the present application scheme, positioning holes and sliding grooves are provided on the surfaces of the side panels, and suitable positioning holes are selected according to the size of the glass before placing the glass, and the second clamping plate is installed in the corresponding positioning holes. After placing the glass, the first clamping plate placed in the sliding groove is moved to clamp the glass, so that the glass can be clamped. There is no need to hold the glass steady by hand, and there is no need to move the second positioning plate. The second positioning plate has already supported the glass, avoiding scratches on the glass surface during the process of holding the glass by hand, and also reducing the steps of clamping the glass, thereby improving the efficiency of glass transportation.

[0012] Furthermore, threaded holes are opened on the upper parts of the two side panels, the threaded holes are connected with the top end of the slide groove, and an adjusting bolt is threadedly connected in the threaded holes. After the glass is installed in the tooth block between the first clamping plate and the second clamping plate, the state of the glass between the first clamping plate and the second clamping plate is relatively loose. By rotating the adjusting bolt clockwise, the first clamping plate can be squeezed by the adjusting bolt, thereby allowing the first clamping plate to clamp the glass.

[0013] Furthermore, a rack is provided on the top of the third plywood, and a plurality of liftable lifting columns are installed on one side of the rack of the third plywood. A transverse groove is opened on the top of the lifting column. At the same time, a straight elastic rope is laterally tightened on one side of the third plywood, and the height of the elastic rope is half of the height of the rack. The lifting column, when the glass is placed, the third plywood is often used to support the bottom end of the glass. When the glass is placed, the glass will fall onto the tooth block of the third plywood. If the falling glass is not buffered, the corners of the glass will cause bumps, affecting the appearance of the glass. However, the straight elastic force can well buffer the glass and reduce the chance of bumps.

[0014] Furthermore, the interior of the third plywood is hollow, and the hollow interior of the third plywood is interconnected with the interior of the lifting column. At the same time, air nozzles for air intake are provided on the side walls at both ends of the third plywood. Since the elastic rope does not need to be stretched straight for a long time, stretching the elastic rope for a long time will affect the life of the elastic rope. When the glass does not need to be transported, the air nozzle releases the gas in the third plywood. At this time, there is no gas in the lifting column. At this time, the lifting column contracts and the elastic rope is in a relaxed state. However, when the glass needs to be transported, gas is filled into the air nozzle to stretch the lifting column, thereby making the elastic rope in a stretched state.

[0015] Furthermore, a slider that can move laterally along the inside of the third plywood is placed in the hollow interior of the third plywood, and the slider divides the hollow interior of the third plywood into a first chamber and a second chamber. Limit blocks for limiting the stroke of the slider are fixed to the inner walls of the first chamber and the second chamber, and two air nozzles are respectively connected to the first chamber and the second chamber; an integrally formed sliding column passing through the side wall of the second chamber is provided at the right end of the slider, and the elastic rope is connected to the end of the sliding column outside the second chamber; at the same time, an air duct is welded under the third plywood, and the air duct connects the interior of the first chamber and the second chamber; at the same time, a miniature overflow valve is installed in the middle of the air duct; since the glass is placed between the first plywood and the second plywood one by one, when the first piece of glass is placed on the third plywood, the elastic rope will move a certain distance accordingly, thereby making the subsequent elastic rope in a stretched state. When the elastic rope is stretched straight, the buffering effect of the elastic rope is not obvious when the glass is put in later. At this time Under the action of the elastic rope, the slider moves toward the second chamber, thereby slightly loosening the part of the elastic rope where no glass is placed, so that when the subsequent glass is placed, the elastic rope can remain in an elastic state and continue to provide a buffer for the subsequent glass. However, when the slider moves toward the second chamber, the pressure in the second chamber increases due to the reduction in the space in the second chamber, and the air pressure in the second chamber can be reduced by the overflow valve arranged in the air pipe; at the same time, the length of the elastic rope will change during long-term use, so that the elastic rope cannot be stretched straight even when the lifting column is raised. At this time, air is inflated into the second chamber, so that the slider slides toward the first chamber, and the elastic rope that has been stretched for a long time is further stretched straight. With the entry of gas and the movement of the slider, the pressure in the second chamber is in a normal state. However, the space in the first chamber is reduced, causing the pressure to increase. At this time, the pressure in the first chamber can be reduced by the micro-overflow valve.

[0016] Furthermore, a screw is provided at one end of the elastic rope extending into the second chamber, and a through hole is opened in the middle wall of the screw to penetrate the screw transversely. The elastic rope passes through the through hole and is rotatably connected to one side of the slider. By screwing in the screw, the elastic rope, which has become longer due to long-term use, can be put in a straightened state. At this time, there is no need to inflate the second chamber, and the straightening of the elastic rope can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following is further described in detail through specific implementation methods:

[0025] Attach Figure 2 For example, the positioning hole 6-1 is arranged in front of the side plate 1, and the slide groove 6 is arranged behind the positioning hole 6-1 to attach Figure 1 For example, the side panels 1 are respectively arranged on the left and right sides, which are used as direction references.

[0026] The embodiment is basically as shown in the attached Figure 1 As shown:

[0027] After the glass 2 is processed by CNC, the thickness of the glass 2 is 0.8 mm. At this time, the processed glass 2 is transported to the ultrasonic cleaning machine for cleaning through the glass 2 transport rack. The glass 2 transport rack is composed of two side panels 1. The front and rear ends of the two side panels 1 are connected by a fixing rod, and the side of the fixing rod is connected to the side of the side panel 1 by a screw.

[0028] As attached Figure 2 As shown, the upper front part of the two side panels 1 is provided with horizontally evenly distributed positioning through holes 6-1, and the second clamping plate 1-2 is placed inside the two side panels 1. The two ends of the second clamping plate 1-2 are set to be screw-shaped. The screws 10 at both ends pass through the positioning holes and are tightened and fixed with butterfly nuts; at the same time, a horizontal slide groove 6 is provided behind the positioning through hole 6-1, and a first clamping plate 1-1 that can move along the slide groove 6 is provided in the slide groove 6. The structure of the first clamping plate 1-1 is consistent with that of the second clamping plate 1-2. The screw 10 of the second plywood 1-2 passes through the slide groove 6 and is tightened and fixed with a butterfly nut; a plurality of transverse waist-shaped grooves 7 are opened under the two side panels 1, and the center lines of the plurality of waist-shaped grooves 7 are on the same vertical line, and two third plywood 3 are inserted into the waist-shaped grooves 7, and the two ends of the two third plywood 3 pass through the waist-shaped grooves 7 and are fixed with locking nuts; the two side panels 1, the first plywood 1-1, the second plywood 1-2 and the two third plywood 3 are combined to form a simple frame structure.

[0029] As attached Figure 1 As shown, a rack 1-3 with a tooth block is provided on the side opposite to the first plywood 1-1 and the second plywood 1-2, and a rack 1-3 is also provided on the top of the third plywood 3. The rack 1-3 is preferably made of polytetrafluoroethylene (PTFE). When the glass 2 needs to be placed on the glass 2 transfer rack, the side on which the third plywood 3 is installed faces the ground. At this time, according to the size of the glass 2, the second plywood 1-2 is pre-clamped in the corresponding positioning through hole 6-1, and then the second plywood 1-2 is tightened with a butterfly bolt, and then the third plywood 3 is inserted into the corresponding waist-shaped groove 7 and tightened with a tightening nut, and then the glass 2 is placed in the tooth grooves of the rack 1-3 of the second plywood 1-2 and the third plywood 3, the second plywood 1-2 and the third plywood 3 support the glass 2, and then the other side of the glass 2 is clamped by moving the first plywood 1-1 installed in the slide groove 6.

[0030] As attached Figure 1 and attached Figure 2 As shown, a threaded hole is provided at one end of the slide groove 6, the threaded hole is connected with the slide groove 6, and an adjusting bolt 5 is installed in the threaded hole. By rotating the adjusting bolt 5 clockwise, the adjusting bolt 5 can be screwed into the slide groove 6 and push the first clamping plate 1-1 to move. After the glass 2 is fully installed in place, the clamping of the glass 2 by the first clamping plate 1-1 is in a loose state. At this time, the first clamping plate 1-1 is moved by adjusting the bolt 5 to further clamp the glass 2, and then the butterfly bolts connecting the two ends of the first clamping plate 1-1 are tightened.

[0031] As attached Figure 3 As shown, when the glass 2 is placed on the rack 1-3 of the third splint 3, the glass 2 falls freely into the tooth groove of the rack 1-3 within a small distance. At this time, the free-falling glass 2 needs to be buffered and decelerated; the interior of the third rack 1-3 is hollow, and an elastic rope 9-2 is pulled on one side of the rack 1-3 of the third splint 3. The height of the elastic rope 9-2 is 1 / 2 of the tooth block of the rack 1-3. At the same time, a plurality of vertical lifting columns 4 are fixed on one side of the rack 1-3. The lifting columns 4 are located at the center of the teeth of the rack 1-3. 4 avoids the tooth grooves of the rack 1-3, the interior of the lifting column 4 is connected with the hollow interior of the third clamping plate 3, a transverse groove is opened on the top of the lifting column 4, the elastic rope 9-2 is stuck in the groove, the lifting column 4 supports the elastic rope 9-2, and keeps the elastic rope 9-2 in a straight state, when the glass 2 "falls" into the tooth grooves of the third clamping plate 3, the straightened elastic rope 9-2 can buffer the glass 2, one end of the elastic rope 9-2 is fixed to the inner wall of the side plate 1, and the other end of the elastic rope 9-2 extends to the hollow part of the third rack 1-3.

[0032] A slider 9 that can move horizontally along the third clamping plate 3 is placed in the hollow interior of the third clamping plate 3. The slider 9 divides the interior of the third clamping plate 3 into two chambers. The left side of the slider 9 is the first chamber 8, and the right side of the slider 9 is the second chamber 8-1. An integrally formed sliding column passing through the side wall of the second chamber 8-1 is provided at the right end of the slider 9. The elastic rope 9-2 is connected to the end of the sliding column outside the second chamber 8-1. A limit block for limiting the moving distance is fixedly welded to the inner wall of the first chamber 8 and the inner wall of the second chamber 8-1. A positioning block 9-3; an air nozzle 9-4 for intake air into the third clamping plate 3 is fixed at the bottom of the first chamber 8 and the second chamber 8-1 respectively, and a tension spring 9-1 is installed and fixed in the second chamber 8-1, and the two ends of the tension spring 9-1 are respectively fixed to the inner wall of the third clamping plate 3 and the side wall of the slider 9; a connecting airway 8-3 is fixedly welded at the lower part of the first chamber 8 and the second chamber 8-1, and a small overflow valve 8-2 is fixed in the middle of the airway 8-3, and the inlet end of the overflow valve 8-2 is connected to the second chamber 8-1.

[0033] When the glass 2 transfer rack is not in use, the hollow interior of the third splint 3 is at normal pressure. At this time, the lifting column 4 is in a descending state, and the elastic rope 9-2 is in a relaxed state. When the glass 2 shipping rack is needed for transportation, the first chamber 8 and the second chamber 8-1 are inflated through the air nozzle 9-4 installed in the first chamber 8, so that there is a pressure difference between the first chamber 8 and the second chamber 8-1. Under the action of the gas, the slider 9 moves into the first chamber 8. At this time, the lifting column 4 extends upward, and the elastic rope 9-2 is in a taut state; when the glasses 2 are placed one by one in the tooth grooves of the tooth block of the third splint 3, the first glass 2 put down will press the elastic rope 9-2, and the elastic rope 9-2 at the rear will be tightened, which will reduce the buffer of the subsequent glass 2. At this time, the elastic rope in the taut state pulls the slider 9 toward When the slider 9 moves toward the second chamber 8-1, the space of the second chamber 8-1 is reduced and the air pressure increases as the space of the second chamber is reduced. At this time, the excess air in the second chamber 8-1 enters the first chamber through the overflow valve 8-2 to relax the elastic rope 9-2 in a taut state at the rear, thereby ensuring that the glass 2 subsequently placed in can be effectively buffered. However, when the slider 9 moves toward the second chamber 8-1, the space of the second chamber 8-1 is reduced, the air in the second chamber 8-1 is squeezed, and the air pressure increases. Through the overflow valve 8-2 set at the airway 8-3, the inlet end of the overflow valve 8-2 is connected to the second chamber 8-1, and the outlet end of the overflow valve 8-2 is connected to the first chamber 8. The airflow flows from the second chamber 8-1 to the first chamber 8 through the overflow valve 8-2, thereby reducing the pressure in the second chamber 8-1.

[0034] During long-term use, the elastic cord 9-2 will be stretched. At this time, the extension and retraction of the lifting column 4 cannot achieve the effect of straightening the elastic cord 9-2. At this time, gas is filled into the air nozzle 9-4 connected to the second chamber 8-1, and the slider 9 moves toward the first chamber 8. The slider 9 moves to the left, and the stretched elastic cord 9-2 is in a stretched state again; and the internal space of the first chamber 8 is reduced under the movement of the slider 9, and the gas in the first chamber 8 is squeezed, the gas pressure increases, and the overflow valve 8-2 set in the airway 8-3 reduces the gas pressure to avoid damage to the third splint 3.

[0035] The specific implementation process of Example 1 is as follows:

[0036] The operator takes the CNC processed glass 2 off the machine tool and transfers the glass 2 to the ultrasonic cleaning machine for cleaning. In order to reduce the damage of the glass 2 during the transfer process, the glass 2 transfer rack is used for transfer. First, the second clamping plate 1-2 is adjusted according to the size of the transferred glass 2 and placed in the corresponding positioning through hole 6-1 and the second clamping plate 1-2 is fixed with a butterfly bolt; then the third clamping plate 3 of the glass 2 transfer rack is facing the ground, and the opening of the glass 2 transfer part is facing upward; in the embodiment, 0 is filled into the first chamber 8. .3Mpa gas is filled into the second chamber 8-1 at the same time. At this time, due to the pressure difference between the first chamber 8 and the second chamber 8-1, the slider 9 moves toward the first chamber 8. When the slider 9 moves, the elastic rope 9-2 is tightened. When the elastic rope 9-2 is tightened, the lifting column 4 rises under the action of the gas in the first chamber 8. At this time, the glass 2 is inserted into the tooth groove of the rack 1-3 of the first clamping plate 1-1 and the second clamping plate 1-2. When the glass 2 is continuously put in, it is observed that no glass 2 is put in. Is the elastic rope 9-2 at the glass 2 stretched tight? At this time, the elastic rope 9-2 is stretched tight. At this time, the slider moves to the right under the traction of the elastic rope 9-2. The elastic rope 9-2 pulls the slider 9 to move toward the second chamber 8-1. The pressure in the second chamber 8-1 increases. As the slider 9 moves toward the second chamber 8-1, the air pressure in the second chamber 8-1 increases. The airflow in the second chamber 8-1 enters the first chamber 8 through the overflow valve 8-2, so that the position of the slider 9 is in a balanced stage again, thereby making the elastic rope 9-2 is relaxed, and after the elastic rope 9-2 is slightly relaxed, continue to place the glass 2; after all the glass 2 is placed, push the first clamping plate 1-1 to move in the sliding groove 6, so that the first clamping plate 1-1 is clamped on one side of the placed glass 2, and then rotate the adjusting bolt 5 clockwise to clamp the glass 2 between the first clamping plate 1-1 and the second clamping plate 1-2, and then use the butterfly bolt to fix the first clamping plate 1-1; finally, uniformly transport the glass 2 transfer rack with the placed glass 2 to the glass 2 cleaning machine for cleaning.

[0037] Embodiment 2: Different from the above-mentioned embodiment 1, a screw 10 is arranged in the second chamber 8-1, and the rod of the screw 10 extends into the second chamber 8-1. At the same time, the contact surface between the second chamber 8-1 and the screw 10 is threadedly connected, and a transverse through hole is opened in the middle of the screw 10. The elastic rope 9-2 passes through the through hole in the middle of the screw 10 and is rotatably connected with the slider 9; secondly, the airway 8-3 is not connected to the second cavity 8-1; when it is necessary to straighten the elastic rope 9-2 that has been used for a long time and stretched, the screw 10 is rotated clockwise, the screw 10 is pushed into the second chamber 8-1, and the slider 9 is pushed to move toward the first chamber 8, so as to achieve the straightening of the stretched elastic rope 9-2.

[0038] Embodiment 2 Specific implementation method:

[0039] What is different from the above-mentioned embodiment 1 is that during long-term use, the elasticity of the elastic cord 9-2 will decrease, and the slider 9 will not be able to tighten the elastic cord 9-2. At this time, the screw 10 is rotated clockwise to screw the screw 10 into the second chamber 8-1. When the screw 10 enters the second chamber 8-1, the screw 10 pushes the slider 9 to move toward the first chamber 8, and the slider 9 tightens the elastic cord 9-2 again to be in a taut state; secondly, what is different from the embodiment 1 is that the inlet end of the overflow valve 8-2 is connected to the first chamber 8. When the slider 9 moves to the first chamber 8, the excess gas in the first chamber 8 is discharged from the overflow valve 8-2 to the outside air; when the glass 2 is continuously placed, the elastic force of the elastic cord 9-2 will change. At this time, the screw 10 is rotated counterclockwise to move the slider 9 to the right, so that the elastic cord 9-2 becomes relatively loose, thereby avoiding excessive tightening of the elastic cord 9-2 and affecting the buffering effect when the glass 2 is placed.

[0040] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
