Separation device for adhesive glass substrates in coated glass production

Abstract

This application provides a device for separating adhered glass substrates in coated glass production. A tilting plate is tilted and positioned above a conveyor belt. The tilting plate, due to its tilting motion, creates a material passage channel with its bottom end spaced apart from the conveyor belt. The height of the material passage channel is not less than the thickness of the glass substrate and not more than twice its thickness. A sliding stop is slidably positioned above the conveyor belt, along the rotation path of the tilting plate and downstream of the conveyor belt. This application uses the tilting plate to form a material passage channel with a height "not less than the thickness of the glass substrate and not more than twice its thickness." When two adhered glass pieces pass through, they are blocked by the tilting plate because their thickness exceeds the channel height. The hydrogen bonds between the upper and lower glass layers break under stress, achieving separation without manual intervention, reducing labor costs, and minimizing the risk of damage to the glass during manual separation.

Description

Technical Field

[0001] This application belongs to the technical field of coated glass production equipment, and more specifically, it relates to a device for separating adhesive glass substrates used in coated glass production. Background Technology

[0002] When the ambient humidity is high, such as during the rainy season or when the workshop humidity exceeds 60%, a very thin water film will form on the glass surface. Water molecules form hydrogen bonds with the silanol groups on the glass surface. At the same time, the water film between the two pieces of glass will contract due to surface tension, causing the glass to adhere tightly. If the storage time is long, the water in the film will slowly evaporate, and the glass surfaces will "stick" together due to the continuous effect of hydrogen bonds, which is especially noticeable on the smooth surface of float glass.

[0003] In the production of coated glass, the glass substrate needs to be cleaned in order to improve the coating quality. However, if the glass substrate sticks together, it can only be separated manually. This increases labor costs, and the glass substrate is fragile and has a large area, so improper handling can damage it. Utility Model Content

[0004] The purpose of this application is to provide a device for separating adhered glass substrates in the production of coated glass, so as to automatically separate adhered glass and reduce labor costs.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A device for separating adhesive glass substrates used in the production of coated glass is provided, comprising a conveyor belt, a tilting plate, and a sliding baffle. The tilting plate is tiltable and positioned above the conveyor belt. Due to its tilting, the bottom of the tilting plate is spaced apart from the conveyor belt to form a material passage. The height of the material passage is not less than the thickness of the glass substrate and not more than twice the thickness of the glass substrate. The sliding baffle is slidably positioned above the conveyor belt, arranged along the rotation path of the tilting plate and along the conveying direction of the conveyor belt, and is located downstream of the tilting plate.

[0006] In one possible implementation, two substrates are arranged at intervals, with the bottom ends of the substrates abutting the ground. Two drive shafts are rotatably arranged between the two substrates, and a conveyor belt is sleeved on the two drive shafts and is taut. The top of the substrate is higher than the top of the conveyor belt.

[0007] In one possible implementation, the bottom end of the flip plate is chamfered.

[0008] In one possible implementation, the substrate is provided with a flip hole, and the flip plate is provided with flip shafts on both sides. The flip shafts are inserted into the flip holes on the corresponding sides, and a reset assembly is provided between one of the flip shafts and the substrate. When the flip plate is flipped, the reset assembly is configured to have a preload force to reset the flip plate.

[0009] In one possible implementation, the reset assembly includes a mounting cover and a torsion spring, wherein the mounting cover is disposed at the top end of one of its flip shafts, the mounting cover is disposed on the outer side of the substrate on the corresponding side, and the mounting cover is spaced apart from the substrate on the corresponding side; the torsion spring is sleeved on the flip shaft, one end of the torsion spring is connected to the mounting cover, and the other end of the torsion spring is connected to the substrate on the corresponding side.

[0010] In one possible implementation, the reset assembly further includes a protective housing with an opening at one end. The opening end of the protective housing is provided with an outwardly extending mounting ear. The protective housing covers the reset assembly, and bolts are screwed onto the mounting ear and the corresponding side of the base plate to fix the protective housing onto the base plate.

[0011] In one possible implementation, along the conveying direction of the conveyor belt, the upstream side of the flip plate is provided with an installation groove, and a rubber block is provided in the installation groove. The distance from the top of the rubber block to the top surface of the conveyor belt is greater than twice the thickness of the glass substrate.

[0012] In one possible implementation, each of the two substrates has a groove on its opposite sidewall, and the two ends of the sliding stop are respectively inserted into the groove. The substrate has a fixing hole, the axis of which is perpendicular to the long axis of the groove. A fixing bolt is screwed into the fixing hole, and the bottom end of the fixing bolt is pressed against the sliding stop to fix the sliding stop relative to the substrate.

[0013] In one possible implementation, the conveyor belt is provided with a plurality of drive blocks, the thickness of the drive blocks is not greater than the thickness of the glass substrate, and the cross-section of the drive blocks is triangular, with the hypotenuse of the triangle facing away from the flipping plate.

[0014] In one possible implementation, the drive block is a soft rubber structure.

[0015] The beneficial effects of the adhesive glass substrate separation device for coated glass production provided in this application are as follows: Compared with the prior art, this application, by setting up a separation device consisting of a conveyor belt, a tilting plate, and a sliding stop, forms a material passage with a height "not less than the thickness of the glass substrate and not more than twice the thickness" through the tilting plate. When two pieces of adhered glass pass through, they will be blocked by the tilting plate because their thickness exceeds the height of the passage, and the hydrogen bonds between the upper and lower glass layers will break under stress, thus achieving separation. In addition, this device does not require manual intervention and automatically completes the separation, ensuring the orderly progress of subsequent coating processes and reducing process interruptions or product defects caused by adhesion. Furthermore, the downstream sliding stop limits the tilting plate, facilitating the separation of the adhered glass by the tilting plate and improving the reliability of separation.

[0037] The adhesive glass substrate separation device for coated glass production provided in this application will now be described.

[0038] Please refer to the following: Figures 1 to 10 The adhesive glass substrate separation device for coated glass production includes a conveyor belt 1, a tilting plate 2, and a sliding baffle 4. The tilting plate 2 can be tilted and positioned above the conveyor belt 1. The tilting plate 2 can be tilted so that its bottom end is spaced apart from the conveyor belt 1 to form a material passage 201. The height of the material passage 201 is not less than the thickness of the glass substrate 3 and not more than twice the thickness of the glass substrate 3. The sliding baffle 4 is slidably positioned above the conveyor belt 1. The sliding baffle 4 is arranged on the rotation path of the tilting plate 2 and is located downstream of the tilting plate 2 along the conveying direction of the conveyor belt 1.

[0039] The beneficial effects of the adhesive glass substrate separation device for coated glass production provided in this embodiment are as follows: Compared with the prior art, the adhesive glass substrate separation device for coated glass production provided in this embodiment, through the separation device consisting of a conveyor belt 1, a tilting plate 2, and a sliding baffle 4, forms a material passage 201 with a height not less than the thickness of the glass substrate 3 and not more than twice its thickness. When two pieces of adhered glass pass through, they are blocked by the tilting plate 2 because their thickness exceeds the height of the passage, causing the hydrogen bonds between the upper and lower glass layers to break under stress, thus achieving separation. In addition, this device does not require manual intervention and automatically completes the separation, ensuring the orderly progress of subsequent coating processes and reducing process interruptions or product defects caused by adhesion. Furthermore, the downstream sliding baffle 4 limits the tilting plate 2, facilitating the separation of the adhered glass by the tilting plate 2 and improving the reliability of the separation.

[0040] like Figure 1 and Figure 3 As shown, the system also includes two substrates 101 spaced apart, with the bottom of each substrate 101 abutting the ground. Two drive shafts 102 are rotatably mounted between the two substrates 101. A conveyor belt 1 is fitted onto the two drive shafts 102 and is taut. The top of each substrate 101 is higher than the top of the conveyor belt 1. A drive motor 106 is mounted on each substrate 101, and the power output end of the drive motor 106 is connected to one of its drive shafts 102 to drive the drive shaft 102 to rotate.

[0041] The substrate 101 serves as a support frame, providing a stable mounting base for components such as the conveyor belt 1, the tilting plate 2, and the sliding baffle 4. This prevents components from shifting due to vibrations during the operation of the conveyor belt 1, ensuring the stability of key parameters such as the height of the material passage 201 and the position of the baffle, and guaranteeing consistent separation performance.

[0042] Two drive shafts 102 work together with a taut conveyor belt 1 to make the glass conveying process smoother, prevent the glass from tilting or getting stuck during conveying, ensure that the stuck glass can accurately enter the material passage 201, and reduce separation failures caused by unstable conveying.

[0043] The top of the substrate 101 is higher than the conveyor belt 1, providing ample space for the flipping movement of the flipping plate 2 and the installation and adjustment of the sliding stop bar 4, facilitating the layout and maintenance of subsequent components and enhancing the structural rationality of the device. It also serves to block the glass substrate 3 on the conveyor belt 1, preventing the adhered glass from falling off the conveyor belt 1.

[0044] like Figure 4 As shown, the bottom of the flip plate 2 is chamfered. The chamfer design avoids direct contact between the sharp edge of the bottom of the flip plate 2 and the glass surface, which can reduce scratches and wear on the glass surface during the separation process, ensure the appearance and performance of the glass substrate 3, and reduce the product defect rate.

[0045] The chamfer makes the contact between the flip plate 2 and the glass smoother. When the adhered glass pushes the flip plate 2, the chamfer can reduce the frictional resistance between the two, prevent the glass from getting stuck due to excessive resistance, and ensure a smooth separation process.

[0046] Combination Figure 2 and Figure 4 As shown, the substrate 101 is provided with a flip hole, and the flip plate 2 is provided with flip shafts 202 on both sides. The flip shafts 202 are inserted into the flip holes on the corresponding sides, and a reset assembly 203 is provided between one of the flip shafts 202 and the substrate 101. When the flip plate 2 flips, the reset assembly 203 is configured to have a preload force to reset the flip plate 2.

[0047] In this embodiment, when the tilting plate 2 resets, its bottom end is flush with the top end of the conveyor belt 1, and the force pushing the tilting plate 2 to deform is greater than the frictional force between the glass substrate and the conveyor belt 1. After the adhered glass passes and pushes the tilting plate 2, the pre-tightening force of the reset assembly 203 can give the tilting plate 2 a tendency to reset. Combined with... Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, in the initial state, if the glass plate does not abut against the drive block 105 mentioned below, the flipping plate 2 will block the adhered glass substrate 101 until the drive block 105 pushes the glass plate forward, forcing the flipping plate 2 to flip. After the lower glass substrate 3 passes through the feed channel 201, the flipping plate 2 will reset and block the upper glass substrate 3 until the upper glass substrate 3 is pushed by the next drive block 105, forcing the flipping plate 2 to flip, so that the separated glass can maintain an appropriate distance along the conveying direction of the conveyor belt 1, facilitating subsequent processes.

[0048] In this embodiment, the reset assembly 203 includes a mounting cover 204 and a torsion spring 205. The mounting cover 204 is disposed at the top of one of its flip shafts 202 and is disposed on the outer side of the corresponding side substrate 101, and the mounting cover 204 and the corresponding side substrate 101 are arranged at intervals. The torsion spring 205 is sleeved on the flip shaft 202, one end of the torsion spring 205 is connected to the mounting cover 204, and the other end of the torsion spring 205 is connected to the corresponding side substrate 101.

[0049] The torsion spring 205 stores preload through elastic deformation. Its reset principle is mature and its response is rapid. It can provide reset force in time after the flip plate 2 is subjected to force and flipped. In addition, the torsion spring 205 has a long service life and low maintenance cost, making it suitable for continuous production environments in workshops.

[0050] One end of the torsion spring 205 is connected to the mounting cover 204 and the other end is connected to the base plate 101. By adjusting the initial deformation of the torsion spring 205, the magnitude of the reset preload can be easily adjusted to adapt to the separation requirements of different glasses and enhance the versatility of the device.

[0051] like Figure 5 As shown, the reset assembly 203 also includes a protective box 206. One end of the protective box 206 is open, and the open end of the protective box 206 is provided with an outwardly extending mounting ear 207. The protective box 206 covers the reset assembly 203 inside, and bolts are screwed onto the mounting ear 207 and the corresponding side of the base plate 101 so that the protective box 206 is fixed on the base plate 101.

[0052] The workshop environment may contain dust, moisture, oil, or foreign objects. The protective box 206 can isolate the reset components 203, such as the torsion spring 205 and the mounting cover 204, from the outside environment, preventing the torsion spring 205 from getting stuck, corroded, or failing due to the adhesion of impurities, thus extending the service life of the reset components 203 and reducing the equipment failure rate.

[0053] The protective box 206 is fixed to the base plate 101 by mounting ears 207 and bolts, which can prevent the components of the reset assembly 203 from accidentally falling off when the flip plate 2 moves, thus avoiding damage to operators or surrounding equipment and complying with production safety regulations.

[0054] like Figure 4As shown, along the conveying direction of the conveyor belt 1, the flip plate 2 is provided with an installation groove on the upstream side, and a rubber block 208 is provided in the installation groove. The distance from the top of the rubber block 208 to the top surface of the conveyor belt 1 is more than twice the thickness of the glass substrate 3.

[0055] The rubber block 208 is soft in texture. When the glass is conveyed by the conveyor belt 1 to the upstream of the flip plate 2, the glass comes into contact with the flip plate 2. The rubber block 208 can absorb the impact force and prevent the glass from being damaged at the edge due to hard collision with the flip plate 2, so as to protect the glass substrate 3.

[0056] The distance from the top of the rubber block 208 to the conveyor belt 1 is greater than twice the glass thickness, ensuring that the upper glass layer can also impact the rubber block 208 when it collides with the flipping plate 2, thus protecting the upper glass layer. Simultaneously, when the center of the upper glass layer is located behind the lower glass layer, the upper glass layer will flip, as... Figure 9 As shown, the soft rubber block 208 also facilitates the flipping of the upper glass and prevents damage to the edges of the upper glass.

[0057] like Figure 4 As shown, each of the two substrates 101 has a sliding groove 103 on its opposite sidewall. The two ends of the sliding stop 4 are respectively inserted into the sliding groove 103. The substrate 101 has a fixing hole. The axis of the fixing hole is perpendicular to the long axis of the sliding groove 103. A fixing bolt 104 is screwed into the fixing hole. The bottom end of the fixing bolt 104 is pressed against the sliding stop 4 so that the sliding stop 4 is fixed relative to the substrate 101.

[0058] The thickness of the coated glass substrate 3 may vary depending on the model. The position of the sliding baffle 4 can be flexibly adjusted by the slide groove 103. This allows the height of the material passage 201 formed between the bottom end of the flip plate 2 and the conveyor belt 1 to be adjusted when the flip plate 2 comes into contact with the sliding baffle 4. This makes the height of the material passage 201 match the glass thickness, ensuring that the baffle can effectively block the unseparated adhered glass and expand the applicability of the device.

[0059] The fixing bolt 104 tightens the sliding stop bar 4 through the fixing hole, which can stably fix the stop bar in the adjusted position, ensuring the stability of the stop bar's limiting function and improving the reliability of the separation process.

[0060] like Figure 3 and Figure 6 As shown, the conveyor belt 1 is provided with multiple drive blocks 105. The thickness of the drive block 105 is not greater than the thickness of the glass substrate 3, and the cross section of the drive block 105 is triangular, with the hypotenuse of the triangle facing away from the flip plate 2.

[0061] The drive block 105 can push the glass forward along the conveyor belt 1, avoiding slippage caused by the smooth surface of the glass, ensuring that the glass can enter the material passage 201 accurately and smoothly, and reducing separation failure caused by conveying delay.

[0062] The thickness of the drive block 105 is no greater than the thickness of the glass, ensuring that the drive block 105 can only push the lower layer of glass that is stuck together forward, so as to facilitate the separation of the stuck glass. The hypotenuse of the triangle faces away from the flip plate 2, so that when the upper glass slides down from the lower glass, it falls smoothly onto the conveyor belt 1, preventing the glass from being broken.

[0063] Finally, the drive block 105 is a soft rubber structure. Soft rubber has low hardness and moderate friction, which can provide sufficient driving force to push the glass, while avoiding scratches and indentations caused by hard contact with the glass. It is especially suitable for coated glass substrates 3 with extremely high surface quality requirements.

[0064] Rubber is elastic and can absorb minor vibrations during conveyor belt operation, reduce vibration friction between the glass and the drive block, prevent the glass from shifting or colliding due to vibration, and ensure the stability of the conveying process.

[0065] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
