Description

Technical Field

[0001] This invention relates to the field of glass coating technology, and in particular to a glass coating conveying mechanism and control method. Background Technology

[0002] Glass is coated on a horizontal Low-E glass sputtering line. Due to process requirements, the glass needs to maintain a low, uniform speed in the coating section of the line. Downstream of the coating section is the output section, which needs to output the glass at high speed to prevent glass accumulation in the coating section. The glass is divided into multiple batches, each batch containing multiple pieces of glass. When part of the same batch of glass is in the coating section and part is in the output section, the output section needs to maintain the same speed as the coating section to avoid glass misalignment caused by speed discrepancies. Therefore, a certain gap must be maintained between adjacent batches of glass to allow the previous batch to exit the output section and the output section to slow down to match the coating section's speed before the next batch of glass enters the output section. However, if the gap between adjacent batches of glass is too large, it will reduce production efficiency. Summary of the Invention

[0003] One object of the present invention is to provide a glass coating conveying mechanism that can shorten the interval between adjacent batches of glass while avoiding glass misalignment, thereby helping to improve production efficiency.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A glass coating conveying mechanism is provided, comprising:

[0006] The transport line includes a coating section, N transition sections and an output section arranged sequentially. Each transition section is equipped with a transition drive unit so that the N transition drive units drive the N transition sections to transport glass respectively, where N is a positive integer greater than 1.

[0007] A detection component for detecting the position of the glass.

[0008] Optionally, the coating section and part of the transition section are both disposed within the vacuum coating chamber.

[0009] Optionally, the detection component includes a first position sensor, which is disposed between the coating section and the transition section;

[0010] And / or, the detection component includes a second position sensor disposed between two adjacent transition sections;

[0011] And / or, the detection component includes a third position sensor disposed between the transition section and the output section.

[0012] Optionally, the conveying line further includes a coating drive unit, which is used to drive the coating section to convey glass at a uniform speed;

[0013] And / or, the transport line further includes an output drive for driving the output segment to transport the glass at a constant or accelerated speed.

[0014] Optionally, N is 2, and the transition section includes a first transition section and a second transition section. The glass sequentially passes through the coating section, the first transition section, the second transition section and the output section.

[0015] The transition drive includes a first transition drive and a second transition drive, wherein the first transition drive is used to drive the first transition segment and the second transition drive is used to drive the second transition segment.

[0016] Another objective of this invention is to provide a control method that shortens the interval between adjacent batches of glass while avoiding glass misalignment, thereby helping to improve production efficiency.

[0017] To achieve this objective, the present invention adopts the following technical solution:

[0018] A control method is provided for the glass coating conveying mechanism described above, the control method comprising the following steps:

[0019] The coating section, the N transition sections, and the output section all operate at a constant speed at a first speed.

[0020] When the tail of the previous batch of glass leaves the coating section, the N transition sections and the output section synchronously accelerate to the second speed, while the coating section maintains the first speed.

[0021] When the tail of the previous batch of glass leaves the first transition section closest to the coating section, the first transition section decelerates to the first speed to prepare to receive the head of the next batch of glass. When the tail of the previous batch of glass leaves the second transition section, the second transition section adjusts to the first speed, and so on, while the output section maintains the second speed.

[0022] When the tail of the previous batch of glass leaves the output section, the output section adjusts to operate at the first speed in preparation to receive the head of the next batch of glass.

[0023] Optionally, the first speed is V1, the second speed is V2, and the second speed V2 is greater than the first speed V1.

[0024] Optionally, N is 2, the transition segment includes a first transition segment and a second transition segment, the total length of the transition segment is H, the length of the first transition segment is H1, the length of the second transition segment is H2, the length of the output segment is D, and the overall length of a batch of glass is C, satisfying: H=H1+H2, H1H and C<D.

[0025] Optionally, the distance between two adjacent batches of glass on the coating section is the glass pot spacing L. From the moment the tail of a batch of glass enters the first transition section until the tail of the same batch of glass leaves the first transition section, the first transition section decelerates to the first speed for a duration of t0. The first speed is V1, satisfying: L≥V1×t0.

[0026] Optionally, the duration of the first transition segment accelerating from the first speed to the second speed is t2, the acceleration of the first transition segment accelerating from the first speed to the second speed is a, the duration of the first transition segment decelerating from the second speed to the first speed is t1, and the duration of the tail of the glass from entering to leaving the first transition segment is t3, satisfying:

[0027] a=(V2-V1) / t2, t0=t1+t3;

[0028] When t3 < t2, the formula for calculating t3 is: t3 2 =2H1×t2 / (V2-V1);

[0029] When t3 > t2, the formula for calculating t3 is: t3 = [H1 + (V2 - V1) × t2 / 2] / V2.

[0030] The beneficial effects of this invention are:

[0031] This invention provides a glass coating conveying mechanism, including a conveying line and a detection component. The conveying line comprises a coating section, N transition sections, and an output section arranged sequentially. Each transition section is equipped with a transition drive, so that the N transition drives drive the N transition sections to convey glass, where N is a positive integer greater than 1. The detection component is used to detect the position of the glass. By setting N transition sections, each driven independently, this glass coating conveying mechanism ensures that the speeds of the transition sections and the coating section are consistent when a batch of glass is simultaneously located in both the coating section and the transition section, preventing glass misalignment. When the tail of the glass leaves the coating section, the section containing the glass synchronously increases its speed to improve the conveying speed, maximizing the speed of the glass on the output section and shortening the time required for the glass to pass through the output section. Furthermore, when the tail of the glass leaves the transition section, the transition section can decelerate to maintain consistency with the speed of the coating section to prepare for the next batch of glass. The transition sections provide more time for the output section to convey the previous batch of glass, thereby shortening the distance between two batches of glass and improving production efficiency.

[0032] This invention also provides a control method applied to the aforementioned glass coating conveying mechanism. The control method includes the following steps: the coating section, N transition sections, and the output section all operate at a uniform first speed; when the tail of the previous batch of glass leaves the coating section, the N transition sections and the output section synchronously accelerate to a second speed, while the coating section maintains the first speed; when the tail of the previous batch of glass leaves the first transition section closest to the coating section, the first transition section decelerates to the first speed to prepare for receiving the head of the next batch of glass; when the tail of the previous batch of glass leaves the second transition section, the second transition section adjusts to the first speed, and so on, while the output section maintains the second speed; when the tail of the previous batch of glass leaves the output section, the output section adjusts to the first speed to prepare for receiving the head of the next batch of glass. Using this control method, the aforementioned glass coating conveying mechanism can help improve production efficiency while avoiding glass misalignment. Attached Figure Description

[0042] 800', glass. Detailed Implementation

[0043] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0044] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0045] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0046] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0047] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0048] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0049] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0050] Glass is coated on a horizontal Low-E glass sputtering line. Due to process requirements, the glass needs to maintain a low, uniform speed in the coating section of the line. Downstream of the coating section is the output section, which needs to output the glass at high speed to prevent glass accumulation in the coating section. The glass is divided into multiple batches, each batch containing multiple pieces of glass. When part of the same batch of glass is in the coating section and part is in the output section, the output section needs to maintain the same speed as the coating section to avoid glass misalignment caused by speed discrepancies. Therefore, a certain gap must be maintained between adjacent batches of glass to allow the previous batch to exit the output section and the output section to slow down to match the coating section's speed before the next batch of glass enters the output section. However, if the gap between adjacent batches of glass is too large, it will reduce production efficiency.

[0051] Therefore, this embodiment provides a glass coating conveying mechanism to solve the above problems. This glass coating conveying mechanism can help improve production efficiency while avoiding glass 80° deviation.

[0052] like Figures 1-2 As shown, the glass coating conveying mechanism in this embodiment includes a conveying line and a detection component. The conveying line includes a coating section 1, N transition sections, and an output section 2 arranged sequentially. Each transition section is equipped with a transition drive, so that the N transition drives drive the N transition sections to convey the glass 800, where N is a positive integer greater than 1. The detection component is used to detect the position of the glass 800.

[0053] This glass coating conveying mechanism, by setting up N transition sections, each driven independently, ensures that when a batch of glass 800 is simultaneously located in both coating section 1 and the transition section, the speeds of the transition sections and coating section 1 remain consistent, preventing the glass 800 from shifting. When the tail of the glass 800 leaves coating section 1, the section containing the glass 800 synchronously increases its speed to improve the conveying speed, maximizing the speed of the glass 800 on output section 2 and shortening the time required for the glass 800 to pass through output section 2. Furthermore, when the tail of the glass 800 leaves the transition section, the transition section can slow down to maintain consistency with the speed of coating section 1, ready to receive the next batch of glass 800. The transition sections provide more time for output section 2 to transport the previous batch of glass 800, thereby shortening the distance between two batches of glass 800 and improving production efficiency.

[0054] Optionally, the conveying line also includes a coating drive unit 6, which drives the coating section 1 to convey the glass 800 at a constant speed. That is, the conveying speed of the coating section 1 is controlled independently. In this embodiment, the coating section 1 is relatively long and includes multiple coating segments, which are driven by multiple coating drive units 6 respectively. Since the coating section 1 is required to convey the glass 800 at a low and constant speed as a whole, the operating power of the multiple coating drive units 6 is the same.

[0055] Optionally, the conveyor line also includes an output drive unit 7, which is used to drive the output section 2 to convey the glass 800 at a constant or accelerated speed. That is, the output section 2 independently controls the conveying speed so that when the tail of the glass 800 leaves the coating section 1, the transition section and the output section 2 can accelerate synchronously. Subsequently, as this batch of glass 800 moves forward, whichever transition section the tail of the glass 800 leaves can be decelerated independently to match the speed of the coating section 1, while the output section 2 can still maintain a high-speed constant speed until the tail of the glass 800 leaves the output section 2. At this point, the output section 2 decelerates to match the speed of the nearest transition section, in order to prepare to receive the head of the next batch of glass 800.

[0056] Optionally, in this embodiment, N is 2. The transition segment includes a first transition segment 8 and a second transition segment 9. The first transition segment 8 is closer to the coating segment 1 than the second transition segment 9. That is, the glass 800 will sequentially pass through the coating segment 1, the first transition segment 8, the second transition segment 9, and the output segment 2. The transition drive includes a first transition drive 10 and a second transition drive 11. The first transition drive 10 is used to drive the first transition segment 8, and the second transition drive 11 is used to drive the second transition segment 9.

[0057] Since the coating area is located in the middle of the vacuum coating chamber, the portion of the vacuum coating chamber near the tail of coating section 1 is not within the coating area. To accelerate the glass 800 process earlier and shorten the distance between two batches of glass 800, optionally, coating section 1 and part of the transition section are both located within the vacuum coating chamber. Optionally, in this embodiment, coating section 1 and the first transition section 8 are both located within the vacuum coating chamber, while the second transition section 9 is not located within the vacuum coating chamber.

[0058] Optionally, the coating drive 6, the two transition drives, and the output drive 7 are all servo motors. The coating section 1, the first transition section 8, the second transition section 9, and the output section 2 each include multiple rollers arranged in parallel and spaced apart. The coating drive 6 drives the multiple rollers of the coating section 1 to rotate synchronously, the first transition drive 10 drives a single roller of the first transition section 8 to rotate, the second transition drive 11 drives the multiple rollers of the second transition section 9 to rotate synchronously, and the output drive 7 drives the multiple rollers of the output section 2 to rotate synchronously.

[0059] Optionally, the detection component includes a first position sensor 3, which is disposed between the coating section 1 and the transition section to detect whether a batch of glass 800 is passing between the coating section 1 and the transition section, or whether the tail of the previous batch of glass 800 has passed through, or whether the head of the next batch of glass 800 has reached this position.

[0060] Optionally, the detection component includes a second position sensor 4, which is disposed between two adjacent transition sections to detect whether a batch of glass 800 is passing between the two transition sections, or whether the tail of the previous batch of glass 800 has passed through, or whether the head of the next batch of glass 800 has reached this position.

[0061] Optionally, the number of second position sensors 4 is related to the number of transition sections, and a second position sensor 4 needs to be set between any two adjacent transition sections.

[0062] Optionally, the detection component includes a third position sensor 5, which is disposed between the transition section and the output section 2 to detect whether a batch of glass 800 is passing between the transition section and the output section 2, or whether the tail of the previous batch of glass 800 has passed through, or whether the head of the next batch of glass 800 has reached this position.

[0063] Optionally, the first position sensor 3, the second position sensor 4, and the third position sensor 5 are all photoelectric sensors. Each photoelectric sensor consists of a light-emitting element and a light-receiving element. When the glass 800 enters the detection area, the light is blocked or reflected. The receiving element converts the light signal into an electrical signal, thereby determining the position of the glass 800. Of course, the length of a batch of glass 800 can also be calculated based on the duration of light blocking.

[0064] Optionally, the glass coating conveying mechanism also includes a controller. The detection component, coating drive 6, first transition drive 10, second transition drive 11, and output drive 7 are all communicatively connected to the controller. The controller can adjust the output power of each drive in real time according to the position of the glass 800, that is, adjust the conveying speed of each segment to make the conveying more compact, shorten the distance between two batches of glass 800, and improve production efficiency. Optionally, the controller can be a Siemens S7-1200 / 1500 series, which supports high-speed counting and motion control. It can determine the length and the position of the beginning and end of a batch of glass 800 based on the detection results of multiple position sensors, calculate and control the output power of each drive to control the conveying speed of each segment. Optionally, in other embodiments, the controller can also be a Mitsubishi Q / R series or an Omron NJ / NX series, etc.

[0065] like Figure 3 As shown, this embodiment also provides a control method applied to the above-mentioned glass coating conveying mechanism. The control method includes the following steps:

[0066] First, coating section 1, the N transition sections, and output section 2 all operate at a constant speed to ensure that the glass 800 moves forward at a low and constant speed in coating section 1, in accordance with the coating requirements. It should be noted that the previous batch of glass 800 and the next batch of glass 800 mentioned below refer to any two adjacent batches of glass 800.

[0067] When the tail of the previous batch of glass 800 detaches from the coating section 1, the N transition sections and the output section 2 simultaneously accelerate to the second speed to ensure that the coated glass 800 is transported at high speed. The coating section 1 always maintains the first speed, and the second speed is greater than the first speed.

[0068] When the tail of the previous batch of glass 800 leaves the first transition section closest to the coating section 1, the first transition section quickly decelerates to the first speed to prepare to receive the head of the next batch of glass 800. This ensures that when part of the glass 800 is on the coating section 1 and part is on the first transition section, the conveying speeds of the coating section 1 and the first transition section are consistent, preventing the glass 800 from shifting due to inconsistent speeds.

[0069] When the tail of the previous batch of glass 800 disengages from the second transition section, the second transition section quickly adjusts to match the speed of the first transition section. In this embodiment, the speed of the first transition section is the first speed at this time. Therefore, the speed of the second transition section also decreases to the first speed to prepare for receiving the head of the next batch of glass 800. This ensures that when part of the glass 800 is on the first transition section and part is on the second transition section, the transport speeds of the first and second transition sections are consistent, preventing the glass 800 from shifting due to inconsistent speeds. Output section 2 only carries the previous batch of glass 800, and output section 2 maintains the second speed, that is, it maintains high-speed transport of the previous batch of glass 800.

[0070] Similarly, if there is a third transition section between the second transition section and the output section 2, when the tail of the previous batch of glass 800 leaves the third transition section, the third transition section quickly adjusts to match the speed of the second transition section. In this embodiment, the speed of the second transition section is the first speed at this time. Therefore, the speed of the third transition section also drops to the first speed to prepare to receive the head of the next batch of glass 800, so as to ensure that when part of the glass 800 is on the second transition section and part is on the third transition section, the transport speed of the second transition section and the third transition section are consistent, preventing the glass 800 from shifting due to inconsistent speeds.

[0071] Until the tail of the previous batch of glass 800 is separated from the output section 2, the output section 2 is quickly adjusted to match the speed of the nearest transition section. In this embodiment, the speed of the nearest transition section is the first speed. Therefore, the speed of the output section 2 is also reduced to the first speed to prepare to receive the head of the next batch of glass 800.

[0072] If both the first transition section 8 and the second transition section 9 are part of the output section 2, then when the previous batch of glass 800 is still being transported at the end of the output section 2, the output section 2 is in a high-speed transport state, and therefore cannot receive the next batch of glass 800, so that the next batch of glass 800 is partially located on the low-speed coating section 1 and partially on the high-speed output section 2. However, the glass coating transport mechanism of this embodiment, by setting N transition sections, can reduce its speed to synchronize with the coating section 1 when the previous batch of glass 800 is still being transported at the end of the output section 2, and receive the next batch of glass 800, thus shortening the gap between the two batches of glass 800. Furthermore, when the tail of the previous batch of glass 800 disengages from the first transition section 8, the first transition section 8 can reduce its speed and receive the next batch of glass 800. By setting multiple transition sections, the gap between the two batches of glass 800 can be further shortened, improving production efficiency. The glass coating transport mechanism described above, using this control method, can significantly improve production efficiency while avoiding glass 800 deviation.

[0073] In this embodiment, the first speed is V1, the second speed is V2, and the second speed V2 is greater than the first speed V1.

[0074] Optionally, N is 2. The transition segment includes the first transition segment 8 and the second transition segment 9. The total length of the transition segment is H. The length of the first transition segment 8 is H1. The length of the second transition segment 9 is H2. The length of the output segment 2 is D. The overall length of a batch of glass 800 is C, satisfying: H=H1+H2, H1H and C<D.

[0075] Optionally, the distance between two adjacent batches of glass 800 on the coating section 1 is the glass pot spacing L. The tail of one batch of glass 800 enters the first transition section 8 and continues until the tail of the same batch of glass 800 leaves the first transition section 8. Then the first transition section 8 decelerates to the first speed for a duration of t0. The first speed is V1. It is necessary to satisfy: L≥V1×t0 to ensure that the first transition section 8 is ready to receive the next batch of glass 800 and to prevent the speed of the multiple sections where the glass 800 is located from being inconsistent, resulting in displacement or wear.

[0076] Optionally, the time for the first transition segment 8 to accelerate from the first velocity to the second velocity is t2, the acceleration of the first transition segment 8 from the first velocity to the second velocity is a, the time for the velocity of the first transition segment 8 to decrease from the second velocity to the first velocity is t1, and the time for the tail of the glass 800 to leave the first transition segment 8 is t3. It is known that a = (V2 - V1) / t2, and t0 = t1 + t3. When the glass pot spacing L takes the minimum safe value V1 × t0, that is, under the premise of ensuring that the glass 800 does not deviate or wear, the interval between two adjacent batches of glass 800 is shortened to the maximum extent, improving coating and transportation efficiency. Therefore, it is necessary to calculate the value of t0. First, the calculation formula for t3 needs to be obtained based on the relationship between t3 and t2.

[0077] When t3 < t2, since the velocity of V1 is relatively small compared to V2, it can be ignored in the calculation, thus yielding H1 = a × t3. 2 / 2. Therefore, the formula for calculating t3 is: t3 2 =2H1×t2 / (V2-V1)

[0078] When t3 > t2, H1 = (V1 + V2) × t2 / 2 + V2 × (t3 - t2), therefore the formula for calculating t3 is: t3 = [H1 + (V2 - V1) × t2 / 2] / V2.

[0079] like Figure 4As shown, in this embodiment, N=2, the first speed is 5 m / min, the second speed is 90 m / min, the lengths of the first transition section 8, the second transition section 9, and the output section 2 are 300 mm, 1000 mm, and 6000 mm, respectively, and the length of a batch of glass 800 is 3688 mm. It should be noted that there are slight gaps between the sections, which can be ignored here.

[0080] The time t1 for the second speed to decrease to the first speed is 1.5 seconds, and the time t2 for the first speed to accelerate to the second speed is 1.2 seconds. During the acceleration from V1 (5 m / min) to V2 (90 m / min), the distance traveled is 850 mm, and t3 is less than t2. According to the above calculation formula, t3... 2 =2H1×t2 / (V2-V1), and t3 is calculated to be 0.5 seconds.

[0081] Based on the minimum safe value of the glass pot spacing L, V1×t0=(t3+t1)×V1, the minimum safe value of the glass pot spacing L is calculated to be 0.167 meters. That is, the glass coating conveying mechanism of this embodiment can reduce the spacing between two batches of glass 800 to 0.167 meters while ensuring that the glass 800 does not shift.

[0082] like Figure 5 As shown, in the prior art, N=1, which is equivalent to merging the first transition section 8 in this embodiment into the coating section 1. When the length of each batch of glass 800' is 3688 mm and the first speed is 5 m / min, when the production line runs continuously, the minimum value of the glass pot spacing is measured to be 366.68 mm.

[0083] The existing conveying mechanism can produce about 1,000 batches of glass 800' per day. Under the premise of unchanged production cost, the glass coating conveying mechanism of this embodiment controls the first transition section 8 separately and uses it as a transition section. The minimum safe pot spacing is significantly reduced, and an additional 405.04 square meters of glass 800 can be produced per day, and more than 140,000 square meters of glass 800 can be produced per year, which greatly improves production efficiency.
