Description

Technical Field

[0001] This utility model belongs to the field of substrate glass production, specifically relating to an annealing furnace temperature process adjustment device and a substrate glass annealing furnace. Background Technology

[0002] The mainstream manufacturing process for TFT-LCD substrate glass employs an overflow-downward method. Molten glass flows down from both sides of an overflow brick, converges and fuses at the base of the brick, and then forms a glass sheet under the traction of a traction mechanism. The furnace used to produce the substrate glass has a long, narrow cavity. Within this cavity, heat comes primarily from two sources: the heating devices on both sides of the cavity and the heat carried by the glass sheet itself. The temperature exhibits a gradient change due to the downward distribution of heat within the narrow space. Through process adjustments using heating and cooling devices, specific temperature points are established at each gradient, ensuring that quality parameters such as stress, warpage, and thickness of the formed glass sheet meet standards. However, due to the furnace's internal structure, low-temperature external airflow enters the narrow cavity from the bottom and rises upwards, while the internal airflow remains at a high temperature. This creates a "chimney effect" within the cavity, interfering with the internal temperature field and causing instability in temperature control, thus affecting the quality of the substrate glass production. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an annealing furnace temperature process adjustment device and substrate glass annealing furnace that can maintain and enhance the temperature stability of each forming zone inside the furnace, thereby playing a role in regulating the temperature inside the furnace, assisting in establishing a stable temperature gradient inside the furnace, improving the stability of temperature control inside the furnace, and thus improving the production quality of substrate glass.

[0004] The present invention relates to a temperature control device for an annealing furnace, comprising two support parts and two adjusting blocks. The two support parts are respectively mounted on the furnace body on both sides of the annealing furnace. Each adjusting block is slidably mounted on a single support part. The opposite ends of the two adjusting blocks are stepped with the steps facing opposite directions. The two adjusting blocks can move linearly on their respective support parts to move closer to or further away from each other. When the two adjusting blocks are close together, the stepped areas of the two adjusting blocks overlap.

[0005] Furthermore, the adjusting block includes a block body and a heat insulation structure disposed on the block body.

[0006] Furthermore, the main body of the baffle includes a front end region, a middle end region, and a rear end region arranged sequentially. A first baffle is provided between the front end region and the middle end region. The front end region is bent and its end is fixed to the first baffle to form a front end enclosure. A stepped region is located at one end of the front end enclosure that is away from the middle end region. A second baffle is provided between the middle end region and the rear end region. A third baffle is provided on the side of the rear end region that is away from the middle end region. Reinforcing plates are connected between the first baffle and the second baffle, and between the second baffle and the third baffle. The thermal insulation structure includes several thermal insulation blocks, which are correspondingly arranged in the front end enclosure, the middle end region, and the rear end region.

[0007] Furthermore, at least one side of the main body of the stop block located at the front end enclosure is provided with an expansion opening.

[0008] Furthermore, the side of the support part one that is opposite to the adjusting block is a plane and is slidably engaged by a sliding groove and a slider, so that the adjusting block is slidably mounted on the support part one.

[0009] Furthermore, the annealing furnace temperature process regulating device also includes two propulsion mechanisms, each of which is connected to a single adjusting block to drive the adjusting block to move linearly along the support.

[0010] Furthermore, each of the propulsion mechanisms includes a fixed frame, a push rod, and a movable frame. The fixed frame is used to be mounted on the outer wall of the annealing furnace. The push rod is mounted on the fixed frame and can move and lock along the fixed frame. The movable frame is connected to the end of the push rod and to one end of the adjusting block away from the stepped area.

[0011] Furthermore, the push rod is a threaded rod, and a rotary drive component is provided on the fixed frame. The threaded rod passes through the rotary drive component and engages with it. A slot is provided at one end of the adjusting block away from the stepped area, and an I-shaped block is provided at the end of the movable frame. The I-shaped block is disposed in the slot and fixed to the adjusting block.

[0012] Furthermore, the annealing furnace temperature process regulating device also includes two sealing components. Each sealing component includes two sealing plates, which are slidably mounted on the outer wall of the annealing furnace and located on both sides of the movable frame in a single propulsion mechanism. Both sealing plates are provided with locking elements to fix their positions, and the opposite side of the two sealing plates is provided with a clearance groove for the end of the movable frame to pass through.

[0013] The present invention also provides a substrate glass annealing furnace, which is equipped with the annealing furnace temperature process adjustment device as described above.

[0014] The beneficial effects of this invention are that by moving two adjusting blocks and adjusting the opening between them, the size of the space through which the airflow passes is changed, thereby regulating the flow and distribution of heat in the furnace cavity. This avoids or significantly weakens the upward movement of airflow from the bottom port of the annealing furnace along the furnace cavity, reducing or eliminating the influence of the chimney effect on the internal temperature field of the furnace. It maintains and strengthens the temperature stability of each forming area inside the furnace, thus playing a role in regulating the internal temperature of the furnace. This helps to establish a stable temperature gradient inside the furnace, improves the stability of internal temperature control, facilitates the elimination of stress on the glass plate itself and ensures that the warping index meets the standards, thereby improving the production quality of the substrate glass.

[0015] Before the substrate glass is pulled downwards, the furnace interior needs to be heated. This is achieved by moving two adjusting blocks to full closure. In the closed state, the ends of the two adjusting blocks form a Z-shaped overlapping closure structure. Compared to a planar contact closure structure, the Z-shaped overlapping closure structure has better sealing performance, better ensures the barrier effect, and better avoids barrier failure caused by the rising airflow, thus ensuring the smooth implementation of the heating process.

[0030] like Figures 1-10 As shown, this utility model provides a temperature process regulating device 100 for an annealing furnace, including two support parts 1 and two adjusting blocks 2. The two support parts 1 are respectively mounted on the furnace body on both sides of the annealing furnace 200, and each adjusting block 2 is slidably mounted on a single support part 1, i.e., the two adjusting blocks 2 are slidably mounted on the two support parts 1 respectively. One end of each adjusting block 2 is opposite to the other, and both opposite ends of the adjusting blocks 2 are stepped with the steps in opposite directions, for example... Figures 1-3 As shown. The two adjusting blocks 2 can move linearly on the corresponding support part 1 to bring the two adjusting blocks 2 closer to each other or further apart, thereby adjusting the distance between the two adjusting blocks 2. Since the step directions of the two adjusting blocks 2 at opposite ends are opposite, when the two adjusting blocks 2 are brought closer to each other until they are closed, the step-shaped areas of the two adjusting blocks 2 overlap, that is, as shown. Figure 1 and Figure 2 As shown, the closure between the two adjusting blocks 2 forms a Z-shaped overlapping closure structure.

[0031] The annealing furnace temperature process adjustment device 100 provided by this utility model is used to be installed on the furnace body on both sides of the annealing furnace 200. By moving two adjusting blocks 2, the opening between the two adjusting blocks 2 is adjusted, thereby changing the size of the space through which the airflow 400 passes, adjusting the flow and distribution of heat in the furnace cavity 201, avoiding or significantly reducing the rise of the airflow 400 from the bottom port of the annealing furnace 200 along the furnace cavity 201, so as to reduce or eliminate the influence of the airflow 400 on the internal temperature field of the furnace body caused by the chimney effect, maintain and strengthen the temperature stability of each forming area inside the furnace body, thereby playing a role in regulating the internal temperature of the furnace body, assisting in establishing a stable temperature gradient inside the furnace body, improving the stability of internal temperature control of the furnace body, facilitating the elimination of stress on the glass plate itself and achieving the warping index, thereby improving the production quality of the substrate glass 300. Before the substrate glass 300 is pulled downwards, when the furnace body needs to be heated, the two adjusting blocks 2 are moved to be fully closed. In the closed state, the ends of the two adjusting blocks 2 form a Z-shaped overlapping closure structure. Compared with the planar contact closure structure, the Z-shaped overlapping closure structure has better sealing performance, can better ensure the barrier effect, and can better avoid the barrier failure caused by the rising airflow 400 being pushed open, thus ensuring the smooth implementation of the heating process.

[0032] When in use, the annealing furnace temperature process regulating device 100 can be installed at corresponding positions within the annealing furnace 200 according to actual needs. For example, it can be installed at the bottom of the furnace body on both sides of the annealing furnace 200, i.e., located on both sides of the bottom port of the annealing furnace 200. Alternatively, it can be installed between different forming areas inside the furnace body. These different forming areas, along the direction from the overflow brick 202 to the bottom port of the annealing furnace 200 within the furnace cavity 201, are sequentially: thickness quality adjustment area 205, shaping area 206, stress buffer and rapid shaping area 207, rapid annealing area 208, and complete annealing area 209. The traction mechanism 203 is located at the lower part of the furnace cavity 201. Figure 11 For example, the annealing furnace temperature process control device 100 is located on the furnace body between the stress buffer and rapid shaping zone 207 and the rapid annealing zone 208. In specific applications, it can also be located between other two forming zones as needed. A single annealing furnace 200 can be equipped with one or more annealing furnace temperature process control devices 100.

[0033] Since different forming zones within the furnace body require different temperature field ranges, when the annealing furnace temperature process regulating device 100 is positioned between two forming zones on the furnace body, its closed state can effectively isolate the two forming zones, facilitating separate temperature control for each zone. When the annealing furnace temperature process regulating device 100 is used between two forming zones on the furnace body, a mounting groove is provided on the furnace body between the two forming zones for installing the annealing furnace temperature process regulating device 100. Preferably, the annealing furnace temperature process regulating device 100 also includes two support parts 3, which are respectively positioned on both sides of the furnace body. A single adjusting stop 2 is located between a single support part 1 and a single support part 3, i.e. Figure 1 and Figure 2 As shown.

[0034] In this invention, the adjusting block 2 includes a block body 21 and a heat insulation structure 22 disposed on the block body 21. Based on the heat insulation structure 22, when the two adjusting blocks 2 are closed, they can more effectively isolate the temperature of the two areas.

[0035] The main body 21 of the baffle includes a front end region, a middle end region 212, and a rear end region 213 arranged sequentially. A first baffle 214 is provided between the front end region and the middle end region 212. The front end region is bent and its end is fixed to the first baffle 214 to form a front end enclosure 211. A stepped region is located at one end of the front end enclosure 211 away from the middle end region 212. A second baffle 215 is provided between the middle end region 212 and the rear end region 213. A third baffle 216 is provided on the side of the rear end region 213 away from the middle end region 212. Reinforcing plates 217 are connected between the first baffle 214 and the second baffle 215, and between the second baffle 215 and the third baffle 216. The thermal insulation structure 22 includes several thermal insulation blocks 221, which are correspondingly arranged in the front end enclosure 211, the middle end region 212, and the rear end region 213.

[0036] Since the area where the regulating baffle 2 acts to block and resist the upward flow of air 400 is mainly located at its front end, based on the aforementioned configuration, the front end of the baffle body 21 adopts a bend-formed enclosure structure, which can improve the structural strength of the front end of the baffle body 21. At the same time, the setting of the first baffle 214, the second baffle 215, the third baffle 216 and the reinforcing plate 217 can play a role in horizontal and vertical reinforcement, further improving the overall structural strength of the baffle body 21, thereby improving the overall structural strength of the regulating baffle 2, enhancing its resistance to deformation, and ensuring the overall heat insulation of the regulating baffle 2 through the setting of several heat insulation blocks 221.

[0037] At least one side of the front enclosure 211 of the main body 21 of the baffle has an expansion opening 2111. Several expansion openings 2111 are provided, and they are equidistant from each other. Since the area of ​​the baffle 2 that blocks and resists the upward flow of air 400 is mainly located at its front end, the temperature in the area of ​​the front enclosure 211 on the main body 21 of the baffle is highest during use. Based on the design of this expansion opening, the expansion deformation under high temperature conditions can be fully released, ensuring the integrity and stability of the overall structure of the baffle 2, and reducing the problem of the baffle 2 becoming unusable due to excessive deformation caused by high-temperature expansion.

[0038] The support part 1 and the adjusting block 2 have opposite sides that are flat and are slidably engaged by the sliding groove 11 and the slider 218, so that the adjusting block 2 is slidably mounted on the support part 1. Based on this configuration, while the adjusting block 2 and the opposite side of the support part 1 are slidably engaged, other areas of the opposite side of the adjusting block 2 and the support part 1 are in a planar engagement state, which can reduce the heat loss from inside the furnace body outward along the space between the support part 1 and the adjusting block 2.

[0039] like Figure 4 As shown, the preferred slide groove 11 is an arc-shaped channel, and the slider 218 is a semi-cylinder, forming an arc-shaped sliding fit structure. This structure has good resistance to thermal deformation and maintains smooth sliding motion while ensuring overall structural stability, avoiding jamming or other obstructions to movement. The slide groove 11 can be mounted on the support part 1, and the slider 218 can be mounted on the stop body 21 of the adjusting block 2, or the slide groove 11 can be mounted on the stop body 21 of the adjusting block 2, and the slider 218 can be mounted on the support part 1. The specific configuration can be determined according to actual requirements. The number of slide grooves 11 and sliders 218 can also be determined according to actual requirements.

[0040] In one embodiment of this utility model, the adjustment block 2 and the support part 1 are closely fitted, that is, the friction between the adjustment block 2 and the support part 1 is large, and a large force is required to push the adjustment block 2 to move. After moving, the adjustment block 2 maintains its position under the action of friction.

[0041] In a preferred embodiment of the present invention, the annealing furnace temperature process adjustment device 100 further includes two propulsion mechanisms 4, each of which is connected to a single adjustment block 2 to drive the adjustment block 2 to move linearly along the support portion 1.

[0042] Specifically, each propulsion mechanism 4 includes a fixed frame 41, a push rod 42, and a movable frame 43. The fixed frame 41 is mounted on the outer wall 204 of the annealing furnace 200. The push rod 42 is mounted on the fixed frame 41 and can move and lock along the fixed frame 41. The movable frame 43 is connected to the end of the push rod 42 and to the end of the adjusting block 2 away from the stepped area. The fixed frame 41 is the fixed end of the propulsion mechanism 4. Moving the push rod 42 drives the adjusting block 2 to move through the movable frame 43, and locking the push rod 42 after it moves to the corresponding position can fix the current position of the adjusting block 2. Compared with the method of maintaining the position of the adjusting block 2 by friction, this embodiment has higher stability.

[0043] The push rod 42 is a threaded rod, and a rotary drive component 44 is provided on the fixed frame 41. The threaded rod passes through and meshes with the rotary drive component 44. By rotating the rotary drive component 44, the threaded rod is driven to move under the action of the thread. After stopping the rotation of the rotary drive component 44, the current position of the threaded rod is locked by the self-locking action of the thread. The rotary drive component 44 can be a nut, which is rotatably mounted on the fixed frame 41, and the threaded rod passes through the nut. Rotating the nut drives the threaded rod to move. Alternatively, the rotary drive component 44 can be a worm gear mechanism, which is rotatably mounted on the fixed frame 41. The worm gear has a threaded hole in the middle, and the threaded rod passes through the threaded hole. By rotating the worm, the worm drives the worm gear to rotate, thereby driving the threaded rod to move. In other configurations, the rotary drive component 44 can also be any other structure that can drive the threaded rod to move.

[0044] The adjusting stop 2 has a slot 2161 at one end away from the stepped area, and the movable frame 43 has an I-shaped locking block 431 at its end. The I-shaped locking block 431 is disposed in the slot 2161 and fixed to the adjusting stop 2. Specifically, as shown... Figure 5 As shown, the slot 2161 is formed on the third baffle 216 of the adjusting block 2. The I-shaped block 431 is inserted into the slot 2161 and fixed to the third baffle 216 by screws. Based on this setting, the mating structure of the I-shaped block 431 and the slot 2161 can limit each other. After the screws are fixed, the connection is more secure and can better solve the problem of connection separation caused by thermal deformation.

[0045] The propulsion mechanism 4 also includes a scale 45 and a pointer 46. The length direction of the scale 45 is the same as the length direction of the threaded rod, and one end of the scale 45 is fixed to the outer wall 204 of the furnace body. The pointer 46 is fixed on the movable frame 43 and located above the scale 45. When the movable frame 43 moves, the relative position of the pointer 46 and the scale 45 changes along the length direction of the scale 45, which indicates the current propulsion displacement of the adjusting stop 2, facilitating the operator to perform the corresponding propulsion operation.

[0046] When the annealing furnace temperature process regulating device 100 is used on the furnace body between two forming areas, preferably, the annealing furnace temperature process regulating device 100 also includes two sealing components 5. Each sealing component 5 includes two sealing plates 51, which are slidably mounted on the outer wall 204 of the annealing furnace 200 and located on both sides of the movable frame 43 in the single propulsion mechanism 4. That is, the two sealing components 5 are respectively mounted on the outer wall 204 of the annealing furnace on both sides, and the two sealing plates 51 in a single sealing component 5 are located on both sides of the movable frame 43 in the single propulsion mechanism 4 on one side of the outer wall 204 of the furnace. Each of the two sealing plates 51 is provided with a locking element 52 to fix its position, and the opposite side of the two sealing plates 51 is provided with a clearance groove 511 for the end of the movable frame 43 to pass through. After the two sealing plates 51 in a single sealing component 5 are closed, the end of the movable frame 43 can move normally along the clearance groove 511.

[0047] Based on the above setup, two sealing components 5 can seal the mounting grooves of the annealing furnace temperature process regulating device 100 on the outer walls 204 of the furnace body on both sides of the annealing furnace 200, isolating the furnace body from the outside and reducing heat loss from the furnace. Simultaneously, this does not affect the normal movement of the movable frame 43, i.e., it does not affect the position adjustment of the adjusting block 2. The specific arrangement of the sealing components 5 is as follows: Figures 7-10 As shown, the outer wall 204 of the furnace body on one side has two movable grooves, one above the other. Two sealing plates 51 in a single sealing assembly 5 are correspondingly positioned in the two movable grooves. The locking element is a bolt. Threaded holes are provided in the area corresponding to the movable grooves on the outer wall 204 of the furnace body. The bolts are threaded through these holes, with the ends of the bolts facing the sealing plates 51. Tightening the bolts fixes the current position of the sealing plates 51. When sealing is required using the sealing assembly 5, the two sealing plates 51 in the single sealing assembly 5 are moved to close the gap, and then the bolts are tightened to abut against the sealing plates 51, thus fixing the sealing plates 51 and maintaining a sealed state. This sealing structure is simple, effective, and highly stable.

[0048] To improve the sealing effect when the two sealing plates 51 are closed, the opposite sides of the two sealing plates 51 are stepped and the steps are in opposite directions. Based on this setting, when the two sealing plates 51 are closed, a Z-shaped overlapping closure structure is formed at the closure point.

[0049] This utility model also provides a substrate glass annealing furnace, which is equipped with an annealing furnace temperature process regulating device 100 as described above, i.e. Figure 11As shown. Due to the installation of the annealing furnace temperature process adjustment device 100, the size of the space through which the airflow 400 passes is changed by adjusting the opening between the two adjustment blocks 2, thereby adjusting the flow and distribution of heat in the furnace cavity 201. This avoids or significantly reduces the rise of the airflow 400 from the bottom port of the annealing furnace 200 along the furnace cavity 201, thereby reducing or eliminating the influence of the airflow 400 on the internal temperature field of the furnace caused by the chimney effect. It maintains and strengthens the temperature stability of each forming area inside the furnace, thus playing a role in regulating the internal temperature of the furnace, assisting in establishing a stable temperature gradient inside the furnace, improving the stability of the internal temperature control of the furnace, facilitating the elimination of stress on the glass plate itself and achieving the required warping index, thereby improving the production quality of the substrate glass 300. Before the substrate glass 300 is pulled downwards, when the furnace body needs to be heated, the two adjusting blocks 2 are moved to be fully closed. In the closed state, the ends of the two adjusting blocks 2 form a Z-shaped overlapping closure structure. Compared with the planar contact closure structure, the Z-shaped overlapping closure structure has better sealing performance, can better ensure the barrier effect, and can better avoid the barrier failure caused by the rising airflow 400 being pushed open, thus ensuring the smooth implementation of the heating process.
