Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.

The first embodiment is as follows:

fig. 1 shows a glass coating transfer system according to an embodiment of the present invention, which includes at least a coating vacuum area 11, a photoelectric sensor 12, a shutter 13, an air cylinder 14, a transfer device 15, and a controller 16.

Specifically, the coating vacuum region 11 is defined by a ceiling plate 110, two gates 13 on the left and right sides, fixed closing surfaces (not shown) on the front and rear sides, and a material table 17. For the sake of easy understanding, the basic flow of the glass coating process performed by the glass coating transport system according to the embodiment of the present application will be described by way of example. The basic flow of the glass coating processing can comprise the following steps:

s1: when the coating vacuum area 11 is in an open state, the conveying device 15 conveys the glass to be coated into the coating vacuum area 11;

s2: closing the shutter 13 to switch the coated vacuum region 11 to a closed state;

s3: the pumping device in the coating vacuum area 11 performs pumping operation to make the coating vacuum area 11 in a vacuum state; then, a coating device in the coating vacuum area 11 performs coating processing on the glass to be coated;

s4: after the processing is finished, opening the gate 13 to switch the film coating vacuum area 11 to be in an open state;

s5: the conveyor 15 transports the coated glass out of the coating vacuum zone 11.

S6: and returning to the step S1 and the subsequent steps to continue the coating processing of the subsequent glass to be coated.

The above-described glass coating transfer system is explained in detail below:

the shutter 13 can be opened under the control of the air cylinder 14 to place the plating vacuum region 11 in an open state, and closed under the control of the air cylinder 14 to place the plating vacuum region 11 in a closed state. The opening and closing range of the gate 13 under the control of the cylinder 14 is between a limit opening position and a limit closing position, the limit opening position is a position at which the gate can be opened to the maximum under the control of the cylinder, and the limit closing position is a position at which the gate can be closed to the maximum under the control of the cylinder.

Specifically, the gate 13 can move in a direction perpendicular to the material conveying direction under the control of the air cylinder 14, so that the gate 13 is opened or closed, and accordingly, the coating vacuum area 11 is in an open state or a closed state. For example, as shown in fig. 1, if the material conveying direction is a first horizontal direction (i.e., the x-axis direction in the figure), the moving direction of the gate 13 may be a vertical direction (e.g., the z-axis direction in the figure) or may be a second horizontal direction (i.e., the y-axis direction in the figure).

Further, the shutter 13 of the embodiment of the present application moves up and down in the vertical direction specifically under the control of the cylinder 14 to achieve opening and closing of the shutter 13. When the coating vacuum area 11 is in a closed state as shown in fig. 1, a coating device inside the coating vacuum area 11 can perform a coating operation on the glass inside the coating vacuum area 11; when the coating operation is completed, the shutter 13 can be moved upward and opened under the control of the air cylinder 14, so that the coating vacuum region 11 is in an open state as shown in fig. 2. Similarly, when the coating vacuum region 11 is in the open state shown in fig. 2, it is waited that the coated glass in the coating vacuum region 11 is transferred to the next station, and after the glass to be coated in the previous station is transferred to the current coating vacuum region 11, the gate 13 is moved downward and closed under the control of the cylinder 14, so that the coating vacuum region 11 is switched to the closed state shown in fig. 1.

Specifically, the limit open position of the shutter 13 in the embodiment of the present application refers to a position where the shutter 13 can be fully opened to the maximum extent under the control of the cylinder 14 without the restriction of the photosensor 12, and similarly, the limit closed position is a position where the shutter 13 can be fully closed under the control of the cylinder 14. Further, when the gate 13 moves up and down in the vertical direction under the control of the cylinder 14, the limit opening position is a position (shown in fig. 3) when the bottom of the gate 13 and the top plate 110 are at the same horizontal plane, and the limit closing position is a position (shown in fig. 1) when the bottom of the gate 13 and the material table are at the same horizontal plane.

Specifically, the structure of the cylinder 14 is schematically shown in fig. 4, and the piston 141 moves inside the cylinder, so as to drive the gate 13 to move, and thus, the gate 13 is opened and closed. Specifically, a magnetic switch 142 and a magnetic switch 143 are disposed on the first end and the second end of the cylinder, respectively. When the piston 141 moves to the first end of the cylinder, i.e. coincides with the position of the magnetically sensitive switch 142, the shutter 13 opens to the above-mentioned limit opening position corresponding to the control of the cylinder 14. When the piston 141 moves to the second end of the cylinder 14, i.e. coincides with the position of the magnetically sensitive switch 143, the shutter 13 is closed to the above-mentioned limit closed position under the control of the cylinder 14.

The photoelectric sensor 12 is arranged at a preset position in the opening and closing range of the gate 13; the preset position is a position which is away from the limit closing position by a preset distance, wherein the preset distance is smaller than the distance between the limit opening position and the limit closing position, and the value of the preset distance is larger than the thickness or the width of the glass; when the photoelectric sensor 12 detects that the gate 13 is opened to the preset position, a first feedback signal is sent to the controller 16.

The photoelectric sensor 12 in the embodiment of the present application is disposed at a preset position within the opening and closing range of the gate 13, and the preset position is determined according to the above-mentioned limit opening position, limit closing position, and preset distance. Specifically, the preset distance d is smaller than the distance between the limit opening position and the limit closing position, that is, the stroke d taken by the shutter 13 to open from the limit closing position to the preset position is smaller than the full stroke s taken by the shutter 13 to fully open from the limit closing position to the limit opening position. And, the value of the preset distance d is larger than the thickness or width of the glass, so that when the gate 13 is opened to a preset position, the glass can smoothly enter or exit the coating vacuum region 11 under the conveying of the conveying device 15. Specifically, when the moving direction of the shutter 13 when opened and closed is in the z-axis direction as shown in fig. 1, the preset distance d is specifically larger than the thickness of the glass; when the moving direction of the shutter 13 to open and close is in the y-axis direction as shown in fig. 1, the preset distance is greater than the width of the glass in particular.

In the embodiment of the present application, the photoelectric sensor 12 disposed at the predetermined position immediately sends a first feedback signal to the controller 16 when detecting that the shutter 13 is opened to the predetermined position, i.e., when the shutter is opened to the state shown in fig. 2.

Alternatively, if the full stroke of the gate 13 when fully opened is s, that is, s is the distance between the limit opening position and the limit closing position, and the preset stroke ratio is r, the preset distance d may be specifically d ═ s × r. Illustratively, the preset stroke ratio may be 80% to 90%. Typically, the stroke of the piston movement on the cylinder 14 from the first end to the second end corresponds to the stroke of the shutter 13 from the extreme closed position to the extreme open position, whereas due to the anti-collision arrangement or due to the air pressure difference of the cylinder, a stroke of the last 10% of the stroke of the piston movement from the first end to the second end is typically required to be relatively large, i.e. correspondingly, a stroke of the last ten% is typically required to be relatively large during the complete stroke of the shutter 13 being open. Therefore, the preset stroke proportion is set at 80% -90% specifically, so that the gate 13 does not need to be opened to the last ten percent of the relatively time-consuming stroke, the gate 13 only needs to be opened to 80% -90% state to send a first feedback signal to the controller 16 from the photoelectric sensor 12 in advance, and the glass is conveyed in advance, so that the opening time of the gate is shortened by shortening the opening stroke of the gate, the production beat is shortened, and the production efficiency of glass coating is improved.

A controller 16 for acquiring the first feedback signal; the conveying device 15 is instructed to convey the glass of the coating vacuum area 11 according to the first feedback signal.

In the embodiment of the present application, the controller 16 is specifically configured to control the conveying device 15 to convey the glass, and the conveying device 15 is disposed on the material table and is configured to convey the glass placed on the material table. Specifically, the controller 16 acquires a first feedback signal sent by the photoelectric sensor 12, and controls the conveying device 15 to convey the glass of the coating vacuum region 11 according to the first feedback signal. Specifically, the glass of the coating vacuum region 11 includes the coated glass currently located inside the coating vacuum region 11, and may further include the glass to be coated located outside the coating vacuum region. The conveying device 15 is used for conveying the coated glass out of the coating vacuum area 11 and conveying the glass to be coated into the coating vacuum area 11.

Generally, the glass coating transmission system needs to wait until the magnetic induction switch on the air cylinder detects that the piston moves to the first end of the air cylinder 14, i.e. the gate 13 is fully opened to the extreme opening position (as shown in fig. 3), and a feedback signal is sent to the controller 16 by the magnetic induction switch (as the magnetic induction switch 142 of fig. 4) so that the controller 16 instructs the transmission device 15 to transmit the glass. In the embodiment of the present application, it can be seen from the above description that the photoelectric sensor 12 is added in the glass coating transmission system, when the photoelectric sensor 12 detects that the gate 13 is opened to the preset position, that is, the position shown in fig. 2, the first feedback signal can be immediately sent to the controller 16, and it is not necessary to wait until the gate is completely opened to the limit position to transmit the glass coating, so that the production tact of the glass coating can be shortened, and the generation efficiency of the glass coating can be improved.

Optionally, the controller 16 is further configured to obtain a user input command or a size of the glass to determine a preset distance, which is used to determine a preset position of the photosensor 12.

In the embodiment of the present application, the value of the preset distance may be specifically determined according to an instruction input by a user or a size of the glass. Alternatively, the instruction input by the user may include a specific numerical value of the preset distance directly input by the user, or may include the preset stroke ratio r, and the controller 16 calculates the preset distance d according to the numerical value of the complete stroke s stored in advance. Alternatively, the size of the glass may be specifically the thickness or the width of the glass, and the size of the glass may be input to the controller 16 by a user, or may be sent to the controller 16 after the size of the glass is measured by another sensor for detecting the size of the glass. The controller 16 determines a value larger than the thickness or width of the glass as a preset distance value after acquiring the size of the glass. Optionally, the controller 16 in the embodiment of the present application may also control the movement of the position of the photosensor 12; correspondingly, after the preset distance is determined, the controller 16 controls the photosensor 12 to move to the preset position directly according to the preset distance.

In the embodiment of the application, the controller can accurately determine the preset distance according to the instruction input by the user or the size of the glass, so that the preset position of the photoelectric sensor can be more accurately determined, the opening degree of the gate can be more accurately set, and the success rate and the efficiency of the glass coating transmission system for transmitting the glass are improved.

Optionally, the glass coating transfer system of the embodiment of the present application further includes a pressure sensor provided on the stage of the station downstream of the coating vacuum region 11. Correspondingly, the controller 16 is specifically configured to obtain the first feedback signal and a pressure value measured by the pressure sensor; if the pressure value is smaller than the preset threshold value, the conveying device 15 is instructed to convey the glass of the coating vacuum area 11 according to the first feedback signal.

In the embodiment of the application, after the glass is subjected to the coating processing in the coating vacuum region 11, the glass is specifically conveyed to an objective table located at a station downstream of the coating vacuum region 11, the coated glass on the objective table is further processed by the station, and the glass is continuously conveyed to other stations after the processing is finished, or the coated glass on the objective table is taken away by a worker. The objective table is provided with a pressure sensor for detecting whether the coated glass which is not moved away exists on the objective table. When the pressure value measured by the pressure sensor is greater than or equal to a preset threshold value, the coated glass still exists on the current objective table, and the coated glass cannot receive the incoming of new coated glass; when the pressure value measured by the pressure sensor is smaller than the preset threshold value, the objective table is in an empty state, and the transmission of new coated glass can be received. Therefore, in this embodiment of the application, after the first feedback signal sent by the photoelectric sensor 12 is acquired, the controller 16 needs to combine with the pressure value measured by the pressure sensor, and only when the pressure value is smaller than the preset threshold, it indicates that the stage of the station located downstream of the coating vacuum region 11 is in an empty state, and at this time, the controller controls the conveying device 15 to convey the glass located in the coating vacuum region 11 to the stage of the station located downstream for the next processing.

In the embodiment of the present application, the controller 16, in addition to the first feedback signal sent by the photoelectric sensor 12, also determines whether the objective table can receive the currently coated glass by combining with the pressure value measured on the objective table located at the downstream station of the coating vacuum region 11, and only when the pressure value is smaller than the preset threshold value, instructs the conveying device 15 to convey the glass in the coating vacuum region 11, so that the situation of collision and collision of the glass during the conveying process of the glass can be avoided, and the yield of the glass coating production is improved.

Alternatively, in the embodiment of the present application, when the piston on the cylinder 14 moves to the second end of the cylinder 14, the shutter 13 is closed to the above-mentioned limit closed position under the control of the cylinder 14. In addition, the glass coating transmission system also comprises a magnetic induction switch arranged on the second end of the air cylinder 14; when the magnetically sensitive switch detects movement of the piston to the second end of the cylinder, a second feedback signal is sent to the controller 16. Correspondingly, the controller 16 is further configured to start the air suction device and/or the coating device of the coating vacuum region 11 if the second feedback signal is obtained.

In the embodiment of the present application, the air cylinder 14 of the glass coating conveying system is specifically shown in fig. 4, and includes a magnetic induction switch 143 disposed at a second end of the air cylinder 14. When the magnetically sensitive switch 143 detects movement of the piston to the second end of the cylinder 14, a second feedback signal is sent to the controller 16. After acquiring the second feedback signal, the controller 16 immediately starts the air extractor and/or the coating device of the coating vacuum region 11, and rapidly performs a coating process on the glass entering the coating vacuum region 11, thereby further improving the glass coating efficiency.

Optionally, the controller 16 is further configured to determine the conveying speed of the conveyor 15 based on the glass conveying speed of a station downstream of the coating vacuum zone 11.

In the embodiment of the application, the speed of conveying the glass by the glass coating conveying system can be further increased by properly increasing the conveying speed of the conveying device 15, so that the coating production efficiency is increased. The increase in the conveyance speed v1 is determined according to the glass conveyance speed v2 of the station downstream of the coating vacuum region 11. Specifically, after the glass conveying speed v2 of the downstream station is obtained, the value of v1 can be increased as much as possible on the premise that v1 is less than or equal to v2, for example, v1 is made to be v2, so that the glass conveying speed can be increased, the glass conveyed by the conveying device 15 is prevented from colliding with the glass of the downstream station of the coating vacuum area 11, and the glass coating production efficiency is improved.

Optionally, as shown in fig. 5, the coating vacuum region 11 of the embodiment of the present application may specifically include a first transition region 111, a first buffer region 112, a coating region 113, a second buffer region 114, and a second transition region 115, and each region is opened and closed by the above-mentioned gate 13. Wherein a gas extraction device is arranged in the first transition zone 111 for setting the vacuum level of the first transition zone 111 to a first vacuum level (e.g., -2 mbar). A suction device is provided in the first buffer zone 112 for setting the vacuum level of the first buffer zone 112 to a second vacuum level (e.g., -4 mbar). An air extractor and a coating device are arranged in the coating area 113, after the glass to be coated is introduced into the coating area 113, the vacuum degree of the coating area 113 is further set to a third vacuum degree (for example, -6 mbar) by the air extractor, so that the coating area 113 reaches the vacuum degree required by coating, and then the glass to be coated is processed by the coating device. Similarly, a suction device is provided in the second buffer zone 114 for setting the vacuum level of the second buffer zone 114 to a second vacuum level (e.g., -4 mbar); a suction device is provided in the second transition zone 115 for setting the vacuum level of the second transition zone to a first vacuum level (e.g., -2 mbar). Through the separation of the transition area, the buffer area and the coating area, the vacuum degree is gradually set, so that the coating area for coating processing can be more stably kept at the vacuum degree (third vacuum degree) required by coating under the buffer transition of the buffer area and the transition area, the success rate of glass coating production is further ensured, and the yield of glass coating is improved. In addition, the photoelectric sensors 12 are arranged at the preset positions of the opening and closing ranges of the gates 13 of all the areas, so that the glass can be effectively conveyed among the areas, and the efficiency of glass coating production is improved.

In the embodiment of the application, in the glass coating conveying system, the photoelectric sensor is arranged at the preset position in the opening and closing range of the gate, and when the photoelectric sensor detects that the gate moves to the preset position, the photoelectric sensor sends a first feedback signal to instruct the conveying device to convey the glass in the coating vacuum area. Because the preset position is specifically arranged at the preset position in the opening and closing range of the gate, the distance between the preset position and the limit closing position (namely the preset distance) is specifically smaller than the distance between the limit opening position and the limit closing position and is greater than the thickness or the width of the glass, when the gate is only required to be opened to the preset position enough for the glass to pass through, the conveying device is indicated in advance to convey the glass, so that the next glass coating work can be rapidly carried out continuously, the gate does not need to be waited to be completely opened, the production beat of the glass coating system is shortened, and the production efficiency of the glass coating is improved.

Example two:

fig. 6 is a schematic flow chart of a first glass coating transmission method provided in an embodiment of the present application, which is applied to the controller 16 according to the first embodiment, and is detailed as follows:

in step S601, a first feedback signal is obtained, where the first feedback signal is a feedback signal sent when the photoelectric sensor detects that the gate is opened to a preset position; the gate can be opened under the control of the cylinder to enable the coating vacuum area to be in an open state, and can be closed under the control of the cylinder to enable the coating vacuum area to be in a closed state; the preset position is a position which is a preset distance away from the limit opening position of the gate; the preset distance is smaller than the distance between the limit opening position and the limit closing position, and the value of the preset distance is larger than the thickness or the width of the glass.

In the embodiment of the present application, after the photoelectric sensor is disposed at the predetermined position of the gate of the glass coating film transfer system, the controller 16 establishes a communication connection with the photoelectric sensor. Then, the controller 16 obtains a first feedback signal sent by the photoelectric sensor, where the first feedback signal is a feedback signal sent to the controller 16 when the photoelectric sensor detects that the gate is opened to the preset position. Specifically, the opening and closing operations of the gate and the determination of the preset position may specifically refer to the related description of the first embodiment, and are not described herein again.

In step S602, according to the first feedback signal, a conveying device is instructed to convey the glass in the coating vacuum area.

Generally, the controller of the glass coating transmission system needs to wait until the magnetic induction switch (for example, 142 shown in fig. 4) on the air cylinder detects that the piston moves to the first end of the air cylinder, namely, the gate is completely opened to the extreme opening position (for example, the state shown in fig. 3) and then control the conveying device to convey the glass. In the embodiment of the present invention, when the gate is opened to the state shown in fig. 2, the controller 16 can receive the first feedback signal sent by the photoelectric sensor disposed at the preset position, and immediately send a command to the conveying device after receiving the first feedback signal, so as to control the conveying device to convey the glass in the vacuum coating area. Specifically, the glass of the coating vacuum area comprises coated glass currently located in the coating vacuum area, and can also comprise glass to be coated located outside the coating spreading area. The conveying device is used for conveying the coated glass out of the coating vacuum area and conveying the glass to be coated into the coating vacuum area.

Optionally, before step S601, the method further includes:

In the embodiment of the present application, the value of the preset distance may be specifically determined according to an instruction input by a user or a size of the glass. Optionally, the instruction input by the user may include a specific numerical value of the preset distance directly input by the user, or may include the preset stroke ratio r, and the controller calculates the preset distance d according to the numerical value of the complete stroke s stored in advance. Alternatively, the size of the glass may be specifically the thickness or the width of the glass, and the size of the glass may be input to the controller by a user, or may be sent to the controller after the size of the glass is measured by another sensor for detecting the size of the glass. And after the size of the glass is obtained, the controller determines a value larger than the thickness or the width of the glass as a preset distance value. Optionally, the controller in this embodiment of the application may also control the photoelectric sensor to move the position; correspondingly, after the controller determines the preset distance, the controller directly controls the photoelectric sensor to move to the preset position according to the preset distance.

Optionally, step S601 includes:

correspondingly, the step S602 includes:

In the embodiment of the application, after the controller acquires the first feedback signal sent by the photoelectric sensor, the controller needs to combine with a pressure value measured by the pressure sensor, and only when the pressure value is smaller than a preset threshold value, it is indicated that the objective table of the station located at the downstream of the coating vacuum region is in an idle state, and at this time, the idle conveyer conveys the glass located in the coating vacuum region to the objective table of the station located at the downstream for next processing. The pressure sensor is used for judging whether the object stage of the station at the downstream of the coating vacuum area is in an empty state or not, and then the conveying device is controlled to convey the glass, so that the condition of collision and collision of the glass in the glass conveying process can be avoided, and the yield of glass coating production is improved.

Optionally, the above method for transferring a glass coating further includes:

In the embodiment of the present application, the second feedback signal is specifically a feedback signal sent when the magnetically sensitive switch 143 shown in fig. 4 detects that the piston on the cylinder moves to the second end of the cylinder. After the controller acquires the second feedback signal, the controller judges that the current gate is closed to the limit closing position, namely the current coating vacuum area is in a closed state, at the moment, the air suction device and/or the coating device of the coating vacuum area are/is immediately started, and the coating processing operation is rapidly carried out on the glass entering the coating vacuum area, so that the coating efficiency of the glass is further improved.

Optionally, before the step S602, the method further includes:

In the embodiment of the present application, the controller 16 can also obtain the glass conveying speed v2 of the station located downstream of the coating vacuum region in advance, and then, on the premise of ensuring that the conveying speed v1 of the conveying device is less than or equal to v2, increase the value of v1 as much as possible, for example, make v1 ═ v2, so that the glass conveying speed can be increased, and at the same time, it is ensured that the glass conveyed by the conveying device does not collide with the glass located downstream of the coating vacuum region, thereby improving the glass coating production efficiency.

In the embodiment of the application, the controller can specifically acquire the first feedback signal sent after the photoelectric sensor detects that the gate is opened to the preset position, so that when the gate is only required to be opened to the preset position enough for glass to pass through, the conveying device is indicated in advance to convey the glass, the next glass coating work is rapidly carried out, the gate does not need to be waited for being completely opened, the production beat of the glass coating system is shortened, and the production efficiency of the glass coating is improved.
