Description

Technical Field

[0001] The invention relates to the technical field of glass tempering, and in particular to a production device for a medical radiation protection tempered glass plate and a use method thereof. Background Art

[0002] Medical radiation protection tempered glass is a special glass designed for medical environment and used for radiation protection. The production process of medical radiation protection tempered glass mainly includes: raw material preparation, glass cutting and edge grinding, tempering treatment, radiation protection layer addition (or coating), finished product inspection and packaging, etc.

[0003] The existing technology still has the following deficiencies in the glass tempering process: 1. In the prior art, the glass is directly sent into the tempering furnace for tempering treatment, and it is impossible to test the glass before tempering. If glass with quality problems (such as cracks, bubbles, inclusions, etc.) is sent into the tempering furnace, it may cause the furnace to explode during the tempering process or cause the performance of the tempered glass to fail to meet the standards.

[0004] 2. Glass of different thicknesses requires different processing times in the heating furnace and cooling furnace, but the existing technology cannot automatically measure the thickness of the glass before tempering, which leads to inaccurate heating and cooling times, affecting the subsequent glass tempering effect.

[0005] 3. When the glass is transported to the tempering furnace for tempering treatment, dust, small particles and other impurities are easily attached to the surface of the glass. The presence of these impurities will cause defects in the tempered glass.

[0006] In view of the above problems, the present invention document proposes a production device for a medical radiation protection tempered glass plate and a method for using the same. Summary of the invention

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Example 1: Reference Figure 1 and Figure 2 , a production device, relates to the field of glass tempering technology, the production device is fixedly connected from left to right in sequence with a first conveyor frame 1, a heating furnace 2, a transfer channel 3, a cooling furnace 4 and a second conveyor frame 5. These components are firmly connected by fasteners or other connection methods to ensure the continuity and stability of the production line.

[0029] Reference Figure 1 and Figure 2 The third conveyor frame 6, the fourth conveyor frame 7 and the fifth conveyor frame 8 are fixed in the heating furnace 2, the transfer channel 3 and the cooling furnace 4 respectively. The first conveyor frame 1, the second conveyor frame 5, the third conveyor frame 6, the fourth conveyor frame 7 and the fifth conveyor frame 8 are all provided with conveying components for continuously conveying the glass. The conveying components are composed of a plurality of conveying rollers 9, and two adjacent conveying rollers 9 are connected by a first sprocket and a first chain transmission to achieve synchronous rotation. On one side of the first conveyor frame 1, a motor is fixed through a frame, and the output shaft of the motor is connected to one of the conveying rollers 9 by a second sprocket and a second chain transmission to provide power for the entire conveying system.

[0030] Reference Figure 1 , Figure 2 , Fig. 9 and Fig.10, at the top of the first conveyor frame 1, a first U-shaped frame 18 and a second U-shaped frame 27 are fixed in sequence from left to right. A high-definition camera 23 is arranged in the first U-shaped frame 18 for comprehensive quality inspection of the glass. In order to realize the reciprocating movement of the high-definition camera 23, a detection structure is provided. The detection structure includes a moving groove 19 arranged in the first U-shaped frame 18, and a moving block 21 is slidably connected inside the moving groove 19. In order to realize the reciprocating movement of the moving block 21, a reciprocating screw 20 is rotatably connected inside the moving groove 19, and the moving block 21 is slidably matched with the reciprocating thread groove of the outer wall of the reciprocating screw 20. In this way, when the reciprocating screw 20 rotates, the moving block 21 will reciprocate along the thread groove of the reciprocating screw 20. At the bottom of the moving block 21, a mounting plate 22 is fixed, and the high-definition camera 23 is fixed at the bottom of the mounting plate 22 for photographing the glass and inspecting it. At the same time, two lighting lamps 24 are fixed at the bottom of the mounting plate 22. The two lighting lamps 24 are located on both sides of the high-definition camera 23 to provide lighting for the high-definition camera 23. In order to drive the reciprocating screw 20 to rotate, a driving shaft 25 is rotatably connected to the inner walls of the two sides of the first U-shaped frame 18 that are close to each other. The two driving shafts 25 are connected to the reciprocating screw 20 through synchronous wheels and synchronous belts. It is worth noting that the synchronous wheel diameter of the outer wall of the reciprocating screw 20 is smaller than the synchronous wheel diameter of the outer wall of the driving shaft 25. This arrangement can make the reciprocating screw 20 rotate faster, and can drive the mounting plate 22 to move back and forth quickly during the movement of the glass, so that the high-definition camera 23 can shoot the glass and detect it. A rubber wheel 26 is fixed to one end of the two driving shafts 25 that are close to each other. These rubber wheels 26 touch the outer wall of the adjacent conveying roller 9 to make the rubber wheels 26 rotate with the conveying roller 9. When the glass is transported on the conveying roller 9, the friction between the rubber wheel 26 and the conveying roller 9 drives the driving shaft 25 to rotate, and then drives the reciprocating screw rod 20 to rotate through the synchronous wheel and the synchronous belt.

[0031] Reference Figure 7 and Figure 8 A hollow rotating cylinder 30 is provided in the second U-shaped frame 27 for measuring the thickness of the glass by ascending. In order to realize this function, a measuring structure is provided. The measuring structure includes a plurality of guide rods 29 slidingly passing through the second U-shaped frame 27, and a common mounting frame 28 is fixed at the bottom end of these guide rods 29. A hollow rotating cylinder 30 is rotatably installed in the mounting frame 28, and this hollow rotating cylinder 30 touches the top of the adjacent conveying roller 9 in the first conveying frame 1. A laser distance sensor 31 is fixed on the top inner wall of the second U-shaped frame 27 for detecting the distance the mounting frame 28 moves upward.

[0032] Specifically, when the glass moves to the position of the hollow rotating cylinder 30, it pushes the hollow rotating cylinder 30 and the mounting frame 28 upward, and at this time, the laser distance sensor 31 can detect the upward distance of the mounting frame 28, thereby obtaining the thickness of the glass. The laser distance sensor 31 transmits a signal to the PLC controller, and the PLC controller can control the motor speed of the heating furnace 2 and the cooling furnace 4 according to the thickness of the glass, thereby controlling the heating and cooling time of the glass in the heating furnace 2 and the cooling furnace 4 respectively.

[0033] Reference Figure 1 , Figure 7-Figure 9 , a cleaning structure is also provided on one side of the first conveyor frame 1, which is used to intermittently introduce the heat in the transfer channel 3 into the hollow rotating cylinder 30. The cleaning structure includes a ventilation box 32 fixed on one side of the first conveyor frame 1, and the top of the ventilation box 32 is rotatably connected to one end of the hollow rotating cylinder 30 through a hose 33, which is used to transfer the heat in the ventilation box 32 to the hollow rotating cylinder 30. On one side of the transfer channel 3, a heat conducting pipe 34 is fixed, and the end of the heat conducting pipe 34 away from the transfer channel 3 is fixedly connected to the ventilation box 32. On the inner wall of one side of the ventilation box 32, a closing plate 35 is slidably connected to close one end of the heat conducting pipe 34. A plurality of push rods 36 are fixed on the side of the closing plate 35 close to the first U-shaped frame 18, and one end of these push rods 36 slides and extends to one side of the ventilation box 32. At the same time, a plurality of first tension springs 47 are fixed to the side of the closing plate 35 close to the first U-shaped frame 18 and the inner wall of one side of the ventilation box 32. These first tension springs 47 are respectively sleeved on the outer wall of the corresponding push rod 36. A push plate 37 is slidably connected to the top of the first U-shaped frame 18. A connecting rod 38 is fixed to the bottom of the push plate 37. A trapezoidal block 39 is fixed to the bottom end of the connecting rod 38. When the moving block 21 moves, it will push the push plate 37 and the trapezoidal block 39 to move outward. The inclined surface of the trapezoidal block 39 cooperates with one end of the push rod 36, so as to push the closing plate 35 to move and release the sealing of the heat conducting pipe 34. At this time, the heat in the transfer channel 3 can be injected into the ventilation box 32 through the heat conducting pipe 34. When the moving block 21 is reset, the push plate 37 and the closing plate 35 are reset under the action of the first tension spring 47, so that heat can be intermittently introduced into the ventilation box 32. The heat enters the hollow rotating cylinder 30 through the hose 33 to heat the hollow rotating cylinder 30. Since the outer walls of the hollow rotating cylinder 30 and the corresponding conveying roller 9 are both provided with adhesive layers, these adhesive layers can remove dust from the surface of the glass. When the hollow rotating cylinder 30 is heated, the adhesive on its outer wall can be heated to prevent the adhesive from solidifying and losing its function of sticking to dust. At the same time, in order to ensure that the push plate 37 and the trapezoidal block 39 can be smoothly reset, a second tension spring 40 is fixed to the side of the trapezoidal block 39 close to the first conveying frame 1, and the second tension spring 40 is fixedly connected to one side of the first conveying frame 1.

A plurality of cooling pipes 16 are fixed on one side of the air ducts 15 close to each other, which are used to cool the surface of the glass. The U-shaped connecting pipe 17 is connected to an external cooling fan through a pipeline from one side to provide cold air for the cooling furnace 4.

[0036] Reference Figure 3-Figure 5 , a feed port and a discharge port are respectively provided on both sides of the heating furnace 2 and the cooling furnace 4. The discharge ports and feed ports of the two furnaces are respectively connected to the two sides of the transfer channel 3, forming a smooth production line. In order to ensure that the glass is not affected by the external environment when entering and exiting the furnace, partitions 10 are slidably connected in the feed port and the discharge port. These partitions 10 can be opened and closed by the control of the cylinder 11. Specifically, two cylinders 11 are fixed on the top of the heating furnace 2 and the cooling furnace 4, and one end of the output shaft of the four cylinders 11 is fixedly connected to the top of the corresponding partition 10. When the glass needs to enter or leave the furnace, the corresponding cylinder 11 will extend or shorten, thereby driving the partition 10 to slide, thereby realizing the opening and closing of the feed port or the discharge port.

[0037] Reference Figure 1 , Figure 8 and Fig.10 , a PLC controller is set on one side of the heating furnace 2. This PLC controller is electrically connected to the high-definition camera 23, the laser distance sensor 31, and the motors on one side of the heating furnace 2 and the cooling furnace 4. The high-definition camera 23 can monitor the production process of the glass in real time to ensure the production quality. The laser distance sensor 31 is responsible for detecting the thickness of the glass and transmitting this signal to the PLC controller. After receiving this signal, the PLC controller will calculate the time that the glass should be heated and cooled in the heating furnace 2 and the cooling furnace 4 according to the preset program, and then control the motor speed on one side of the two furnaces, thereby realizing precise control of the heating and cooling time.

[0038] The heating wire 13 is of the same model as the heating wire 13 in the utility model with publication number CN218665749U.

[0039] The convection fan 14 is of the same model as the convection fan 14 in the utility model with publication number CN218665749U.

[0040] Through the arrangement of the above structure, the medical radiation protection tempered glass plate production device of this embodiment can realize the whole process of automatic production such as continuous conveying, heating and tempering, cooling and shaping, and quality inspection of glass. At the same time, through the arrangement of the cleaning structure, the heat in the transfer channel 3 can be effectively utilized to improve the energy utilization efficiency. The entire production device has a compact structure, complete functions, and simple operation, and has high production efficiency and product quality.

[0041] Example 2: Reference Fig.11 A fixed block 41 is fixed on one side of the top of the first conveyor frame 1. A reciprocating screw 42 is slidably penetrated in the fixed block 41 through a slide groove and a slider. A push plate 46 for pushing the glass is fixed to the end of the reciprocating screw 42 close to the heating furnace 2. A first gear 43 is rotatably connected to the side of the fixed block 41 away from the push plate 46. A sliding block that slides with the threaded slide groove on the outer wall of the reciprocating screw 42 is provided in the first gear 43. In this way, when the first gear 43 rotates, the reciprocating screw 42 can be driven to slide in the fixed block 41. In order to realize the rotation of the first gear 43, a drive motor 44 is fixed on the top of the fixed block 41. The output shaft of the drive motor 44 is fixed to a second gear 45 meshing with the first gear 43.

[0042] When the driving motor 44 is started, it drives the second gear 45 to rotate, and the second gear 45 is meshed with the first gear 43, thereby driving the reciprocating screw 42 to slide in the fixed block 41. In this way, the reciprocating screw 42 can push the push plate 46 to move, and push the glass toward the heating furnace 2.

[0043] It is worth noting that the pushing speed of the push plate 46 is designed to be greater than the speed of the conveying roller 9 in the first conveying frame 1 to convey the glass. Therefore, when the push plate 46 pushes the glass to move, it can also put the glass in order. In addition, due to the provision of the hollow rotating cylinder 30 and the laser distance sensor 31, when the push plate 46 pushes the glass to move, it can also move the hollow rotating cylinder 30 upward, thereby facilitating the laser distance sensor 31 to detect the thickness of the glass. In this way, the heating and cooling time can be adjusted according to the detected glass thickness to ensure the quality of the produced medical radiation protection tempered glass plate.

[0044] The method for using the medical radiation protection tempered glass plate production device comprises the following steps: S1. Place the glass on the first conveying frame 1, and convey the glass toward the heating furnace 2 through the multiple conveying rollers 9 thereon. During the conveying process, the driving motor 44 drives the second gear 45 to rotate, and the second gear 45 meshes with the first gear 43. The first gear 43 is provided with a threaded section that slides with the thread groove on the outer wall of the reciprocating screw 42. The reciprocating screw 42 pushes the push plate 46 to move. The push plate 46 can push the glass toward the heating furnace 2, and the pushing speed of the push plate 46 is greater than the speed of the conveying rollers 9 in the first conveying frame 1 to convey the glass. Therefore, the push plate 46 can also place the glass neatly when pushing the glass to move; S2. When the glass moves into the first U-shaped frame 18, the friction between the rubber wheel 26 and the conveying roller 9 drives the driving shaft 25 to rotate. The driving shaft 25 drives the reciprocating screw 20 to rotate through the synchronous wheel and the synchronous belt. The reciprocating screw 20 drives the mounting plate 22 to reciprocate through the moving block 21. The diameter of the synchronous wheel on the driving shaft 25 is larger than the diameter of the synchronous wheel on the reciprocating screw 20. Therefore, the mounting plate 22 rotates at a faster speed, which can drive the mounting plate 22 to reciprocate quickly during the movement of the glass. The high-definition camera 23 can shoot the glass and detect the glass, and the lighting lamp 24 can provide lighting for the high-definition camera 23, so that the high-definition camera 23 can shoot more clearly. When the glass has defects, the staff will take the glass away from the first conveying frame 1, otherwise the glass will continue to be conveyed to one side. S3. When the glass moves to the position of the hollow rotating cylinder 30, the push plate 46 pushes the glass to move and pushes the hollow rotating cylinder 30 and the mounting frame 28 upward. The laser distance sensor 31 can detect the upward distance of the mounting frame 28, thereby detecting the thickness of the glass. The laser distance sensor 31 transmits the signal to the PLC controller, and the PLC controller can control the motor speed on one side of the heating furnace 2 and the cooling furnace 4, thereby controlling the heating and cooling time of the glass in the heating furnace 2 and the cooling furnace 4 respectively. In addition, the outer walls of the hollow rotating cylinder 30 and the conveying roller 9 matched with the hollow rotating cylinder 30 are both adhered with adhesive. During the movement of the glass, the hollow rotating cylinder 30 and the corresponding conveying roller 9 can adhere the dust and small particles on the glass to ensure the cleanliness of the glass surface. S4, then the cylinder 11 and the partition 10 in the heating furnace 2 cooperate to open the feed port of the heating furnace 2, the first conveying frame 1 and the third conveying frame 6 cooperate to convey the glass into the heating furnace 2, the air temperature in the heating furnace 2 is heated by the heating wire 13, and the convection fan 14 blows air into the heating furnace 2 to heat the glass evenly. After heating, the discharge port of the heating furnace 2 is opened, and the heated glass enters the transfer channel 3, while the heat in the heating furnace 2 is lost to the transfer channel 3. Then, the baffle 10 and the cylinder 11 in the cooling furnace 4 cooperate to open the feed port in the cooling furnace 4, and the glass enters the cooling furnace 4. The cold air fan injects cold air into the air duct 15 through the U-shaped connecting pipe 17, and the air duct 15 cooperates with the cooling pipe 16 to cool the surface of the glass to complete the tempering of the glass. After cooling, the cooling furnace 4 opens the discharge port to convey the glass to the second conveying frame 5, and the conveying roller 9 in the second conveying frame 5 conveys the glass to the next process for adding a radiation protection layer. S5. When the moving block 21 reciprocates in the moving groove 19, the moving block 21 pushes the push plate 37 and the trapezoidal block 39 to move outward, and the inclined surface of the trapezoidal block 39 cooperates with the push rod 36 to push the closing plate 35 to move and release the sealing of the heat transfer pipe 34. At this time, the heat in the transfer channel 3 is injected into the ventilation box 32 through the heat transfer pipe 34. After the moving block 21 is reset, the push plate 37 and the closing plate 35 are reset under the action of the second tension spring 40 and the first tension spring 47, so that heat can be intermittently introduced into the ventilation box 32. The heat enters the hollow rotating cylinder 30 through the hose 33 to heat the hollow rotating cylinder 30, and the hollow rotating cylinder 30 can conduct the heat to the conveying roller 9 matched with it, which is used to heat the glue on its outer wall to prevent the glue from solidifying and losing its function of sticking to dust.

[0045] However, as is well known to those skilled in the art, the working principles and wiring methods of the drive motor 44, the lighting lamp 24, the high-definition camera 23, the convection fan 14, the cylinder 11 and the heating wire 13 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience.
