Description

Technical Field

[0001] The present invention relates to the technical field of glass production, and in particular to a glass coating system and a control method of the glass coating system. Background Art

[0002] At present, the offline vacuum magnetron sputtering coating production adopts a five-stage continuous coating process. The glass enters the "import chamber" in the form of a single piece, and then enters the "coating process chamber" after passing through the "import transition chamber". After the glass enters the coating process chamber, under the control of the glass photoelectric sensor switch and the software control program, the glass will maintain a fixed distance between each other for continuous coating process production. After the coating process is completed, the fixed distance is used to separate the glass into single pieces under the control of the glass photoelectric sensor switch and the software control program to enter the "exit transition chamber", and then enter the "exit chamber" to complete the coating process production.

[0003] The coating line has a specific structure (5 chambers, the valve chamber is in the 3rd chamber), and the targets are concentrated in the first three chambers. If the distance between the two glasses is too short, the two glasses cannot be separated in time, which will easily cause the whole line to jump targets, resulting in the scrapping of all the glasses in the chamber. Affected by factors such as transmission acceleration and friction between the glass and the transmission roller, the fixed spacing control is not stable, and the fixed spacing is often too large or too small. When the fixed spacing is too small, the separation at the exit will not be timely, causing the transmission to stop (which is an automatic protection of the vacuum magnetron sputtering coating process equipment), resulting in a large amount of glass in the coating process room being scrapped.

[0004] The current practice is to manually monitor the upper computer interface and judge whether the glass spacing is normal based on experience. Once an abnormal situation occurs, the imported glass transmission is manually suspended. However, manual operation is prone to negligence, and manual judgment has errors, which is very unreliable and can easily reduce production efficiency. Summary of the invention

[0005] The main purpose of the present invention is to provide a glass coating system and a control method for the glass coating system, aiming to facilitate the detection of glass spacing and reduce the production error rate.

[0006] To achieve the above object, the glass coating system proposed by the present invention comprises:

[0007] A main body, wherein the main body is provided with a coating chamber and a glass inlet and a glass outlet communicating with the coating chamber;

[0008] A conveying mechanism, which is disposed in the coating chamber and is used to convey the glass;

[0009] A detection switch, which is disposed in the coating chamber and adjacent to the conveying mechanism, and is used to contact the glass to detect the distance between two adjacent glasses; and

[0010] A controller is electrically connected to the conveying mechanism and to the detection switch, wherein the controller controls the conveying mechanism to convey the glass and controls the detection switch to perform detection.

[0011] Optionally, the detection switch is arranged at one end of the coating chamber adjacent to the glass inlet.

[0012] Optionally, the detection switch is a wheel switch, and the wheel switch includes:

[0013] A body connected to an inner wall of the coating chamber and electrically connected to the controller; and

[0014] A rolling wheel is rotatably arranged at one end of the main body away from the inner wall of the coating chamber, and is used for rolling against the glass.

[0015] Optionally, the body is connected to the bottom wall of the coating chamber.

[0016] Optionally, the detection switches include two, the two detection switches are arranged at intervals, and the connection direction of the two detection switches is arranged perpendicular to the conveying direction of the conveying mechanism.

[0017] Optionally, the glass coating system also includes a backup switch, which is arranged in the coating chamber and is spaced apart from the detection switch in the conveying direction of the conveying mechanism. The backup switch is electrically connected to the controller and is used to contact the glass to detect the distance between two adjacent pieces of glass.

[0018] Optionally, the backup switches include two, the two backup switches are arranged at intervals, and the connection direction of the two backup switches is arranged perpendicular to the conveying direction of the conveying mechanism.

[0019] Optionally, the conveying mechanism includes a plurality of conveying rollers, the plurality of conveying rollers are arranged in the coating chamber at intervals and side by side, and the detection switch is arranged between two adjacent conveying rollers.

[0020] The glass coating system also includes two supporting platforms, which are respectively arranged on opposite sides of the coating chamber, and each of the supporting platforms is provided with a plurality of rotating grooves at intervals, and one end of each conveying roller is rotatably arranged in a rotating groove of one of the supporting platforms, and the other end is rotatably arranged in a rotating groove of the other supporting platform.

[0021] The present invention also provides a control method for a glass coating system, comprising the following steps:

[0022] The glass is sent into the coating chamber from the glass inlet of the main body, and the controller controls the conveying mechanism to convey the glass;

[0023] When the detection switch detects the glass and detects that the glass is separated from the detection switch, the timing starts, and the duration of the timing ending when the detection switch continues to detect the next piece of glass is the first duration;

[0024] Acquire a conveying speed of the conveying mechanism, and calculate a distance between the glass and the next glass according to the first time duration and the conveying speed;

[0025] comparing the spacing with a preset spacing;

[0026] If the distance is smaller than the preset distance, the controller stops sending new glass into the coating chamber.

[0027] The technical solution of the present invention is to send pieces of glass from the glass entrance of the main body into the coating chamber and transmit them through a conveying mechanism so as to facilitate coating of the pieces of glass. At the same time, a detection switch is set in the coating chamber, and the detection switch is set adjacent to the conveying mechanism for contacting the pieces of glass on the conveying mechanism. At the same time, the detection switch and the conveying mechanism are electrically connected to the controller. In this way, the controller controls the conveying mechanism to convey the glass and controls the detection switch to detect. When the detection switch contacts the glass, the controller determines that there is glass here. With the transmission of the conveying mechanism, when the detection switch does not contact the glass, the controller starts to calculate the time when the detection switch contacts the next piece of glass. According to the time and the transmission speed of the conveying mechanism, the distance between two adjacent pieces of glass can be calculated. When the distance is too small, the controller stops conveying the glass into the coating chamber, thereby avoiding the situation where all subsequent glasses are scrapped due to the stop of transmission at the outlet pot, thereby reducing the production error rate.

[0039] The present invention provides a glass coating system 100 .

[0040] Please refer to Figure 1 and Figure 3In an embodiment of the present invention, the glass coating system 100 includes a main body 1, a conveying mechanism 2, a detection switch 3 and a controller (not shown). The main body 1 is provided with a coating chamber 13 and a glass inlet 11 and a glass outlet 12 connected to the coating chamber 13. The conveying mechanism 2 is arranged in the coating chamber 13 for conveying the glass 200. The detection switch 3 is arranged in the coating chamber 13 and is adjacent to the conveying mechanism 2. The detection switch 3 is used to contact with the glass 200 to detect the distance between two adjacent glasses 200. The controller is electrically connected to the conveying mechanism 2 and to the detection switch 3. The controller controls the conveying mechanism 2 to convey the glass 200 and controls the detection switch 3 to perform detection.

[0041] In this embodiment, the main body 1 can be optionally a fully enclosed structure to prevent other debris from entering the coating chamber 13. Of course, the main body 1 can also be a semi-enclosed structure, that is, the coating chamber 13 is enclosed by the bottom wall and four side walls, so that the glass 200 in the coating chamber 13 can be observed from above. Specifically, through holes are provided on the opposite side walls of the main body 1 to form a glass entrance 11 and a glass exit 12 respectively. The through hole is in a long strip shape, so that the glass 200 can lie flat and pass through the glass entrance 11 or the glass exit 12. At the same time, the glass entrance 11 and the glass exit 12 are arranged opposite to each other and are arranged corresponding to the conveying mechanism 2, so that the glass 200 enters the coating chamber 13 from the glass entrance 11 and is carried on the conveying mechanism 2. The conveying mechanism 2 can be a conveyor belt or a conveying channel composed of multiple conveying rollers, as long as the conveying of the glass 200 can be achieved, it is not limited here. It can be understood that the detection switch 3 is arranged adjacent to the conveying mechanism 2 to facilitate contact with the glass 200 on the conveying mechanism 2. It can be understood that the detection switch 3 is a micro switch, which contacts the glass 200 to detect whether the glass 200 exists. Under the transmission of the transmission mechanism 2, the detection switch 3 is in an idle state at the interval between two adjacent glasses 200. By calculating the idle time of the detection switch 3 and multiplying the time by the transmission speed of the transmission mechanism 2, the distance between two adjacent glasses 200 can be obtained.

[0042] The present invention also provides a control method for a glass coating system, comprising the following steps:

[0043] Provide a glass coating system;

[0044] The glass is sent into the coating chamber from the glass inlet of the main body, and the controller controls the conveying mechanism to convey the glass;

[0045] It should be noted that the controller controls the conveying structures of other chambers to convey the glass through the glass entrance. When the controller collects the signal that the glass is conveyed into the coating chamber, the conveying mechanism of the coating chamber conveys the glass.

[0046] When the detection switch detects the glass and detects that the glass is separated from the detection switch, the timing starts, and the duration of the timing ending when the detection switch continues to detect the next piece of glass is the first duration;

[0047] It should be noted that the controller is provided with an acquisition module and a timing module. When the detection switch contacts the glass, a feedback signal is transmitted to the acquisition module. When the acquisition module of the controller does not receive the feedback signal of the detection switch, the timing module starts timing. For example, the first glass and the second glass are successively sent into the coating chamber and are transported by the transport mechanism. When the detection switch is separated from the first glass, the timing module starts timing. When the detection switch contacts the second glass, the timing module ends timing. This duration is determined as the first duration, and so on.

[0048] Optionally, after this step, the following step is further included: comparing the first time length with a preset time length; if the first time length is less than the preset time length, stopping feeding new glass into the coating chamber. It can be understood that, when the transmission speed of the transmission mechanism is consistent, if the first time length is less than the preset time length, it can be determined that the distance between the two glasses is too small.

[0049] Acquire a conveying speed of the conveying mechanism, and calculate a distance between the glass and the next glass according to the first time duration and the conveying speed;

[0050] It should be noted that the controller further includes a calculation module, which can calculate the distance between two adjacent glass pieces by multiplying the first time length by the transmission speed.

[0051] comparing the spacing with a preset spacing;

[0052] If the distance is smaller than the preset distance, the controller stops sending new glass into the coating chamber.

[0053] It is understandable that when the controller stops feeding new glass into the coating chamber, an alarm may be sent to the equipment manager to remind him to handle the problem. After the processing is completed, production can continue.

[0054] The technical solution of the present invention is to feed the glass 200 from the glass inlet 11 of the main body 1 into the coating chamber 13, and to transmit the glass 200 through the conveying mechanism 2, so as to coat the glass 200. At the same time, a detection switch 3 is arranged in the coating chamber 13, and the detection switch 3 is arranged adjacent to the conveying mechanism 2, and is used to contact the glass 200 on the conveying mechanism 2. At the same time, the detection switch 3 and the conveying mechanism 2 are electrically connected to the controller. In this way, the controller controls the conveying mechanism 2 to convey the glass 200, and controls the detection switch 3 to detect. When the detection switch 3 contacts the glass 200, the controller determines that there is glass 200 here. With the transmission of the conveying mechanism 2, when the detection switch 3 does not contact the glass 200, the controller starts to calculate the time when the detection switch 3 contacts the next glass 200, and the distance between two adjacent glasses 200 can be calculated according to the time and the transmission speed of the conveying mechanism 2. When the spacing is too small, the controller stops conveying the glass 200 into the coating chamber 13, thereby avoiding the situation where all subsequent glasses 200 are scrapped due to stopping transmission at the outlet pot, thereby reducing the production error rate.

[0055] like Figure 1 As shown, in one embodiment, the detection switch 3 is arranged at one end of the coating chamber 13 adjacent to the glass entrance 11. The conventional practice of the coating line is to use a photoeye to detect the glass 200, because the valve chamber of the coating line is in the third section, where there is a detection photoeye, but it is too late to detect at this time, and it can only be detected in advance. Optionally, the detection switch 3 is arranged at a position 113 meters away from the glass entrance in the coating chamber 13, where there is no condition for installing a photoeye. It can be understood that when the glass 200 enters the coating chamber 13, the detection switch 3 can be detected in time to detect the distance between two adjacent glasses 200 as soon as possible, so as to solve the problem as soon as possible and reduce the product error rate. At this time, the glass 200 has entered the coating chamber 13 and has been smoothly transmitted, and the detection result is more accurate. Of course, the distance between the detection switch 3 and the glass entrance 11 can be adjusted according to actual conditions, and is not limited here.

[0056] Please refer to Figure 1 and Figure 2 In one embodiment, the detection switch 3 is a wheel switch, which includes a body 31 and a rolling wheel 32. The body 31 is connected to the inner wall of the coating chamber 13. The rolling wheel 32 is rotatably arranged at one end of the body 31 away from the inner wall of the coating chamber 13, and is used for rolling against the glass 200.

[0057] It can be understood that the body 31 is electrically connected to the scroll wheel 32 and the controller respectively, and the scroll wheel 32 rolls against the glass 200 on the conveying mechanism 2, which can reduce the friction between the two and avoid damage to the glass 200 caused by the detection switch 3. Specifically, the conveying mechanism 2 conveys the glass 200 in a plane, and the top of the scroll wheel 32 exceeds the conveying plane of the conveying mechanism 2 by a point, so that the glass 200 can contact the scroll wheel 32 when being conveyed on the conveying mechanism 2. It can be understood that when the glass 200 contacts the scroll wheel 32, the scroll wheel 32 rolls accordingly and presses down the body 31 to trigger the detection.

[0058] In one embodiment, the body 31 is connected to the bottom wall of the coating chamber 13 .

[0059] In this embodiment, the connection method between the body 31 and the bottom wall of the coating chamber 13 can be optionally adhesive, clamping or screw connection, which is not limited here. It can be understood that the rolling wheel 32 is arranged at the upper end of the body 31, and when the rolling wheel 32 rolls in contact with the glass 200, the rolling wheel 32 presses down to provide positive pressure to the body 31, and the detection result is more accurate. At the same time, the pressure on the body 31 can also be borne by the bottom wall of the coating chamber 13. Of course, in other embodiments, the body 31 can also be connected to the side wall of the coating chamber 13, and the detection switch 3 is located at the side of the conveying mechanism 2.

[0060] like Figure 1 As shown, in one embodiment, the detection switches 3 include two detection switches 3 , which are arranged at intervals, and the connection direction of the two detection switches 3 is arranged perpendicular to the conveying direction of the conveying mechanism 2 .

[0061] In this embodiment, the two detection switches 3 are respectively located on opposite sides of the conveying direction of the conveying mechanism 2. When the glass 200 is conveyed on the conveying mechanism 2, the two detection switches 3 respectively detect the opposite sides of the glass 200, that is, the distance between the opposite sides of the glass 200 and the other glass 200 can be detected. It can be understood that the two detection switches 3 detect the distance between the glass 200, and the side with the smallest distance is used as the standard. In this way, when the glass 200 is tilted, one side is closer to the other glass 200 than the other side. The two detection switches 3 are arranged at intervals to more accurately determine the minimum distance between the two glasses 200, thereby effectively avoiding damage to the glass 200 caused by too small a distance.

[0062] In one embodiment, the glass coating system also includes a standby switch 4, which is disposed in the coating chamber 13 and is spaced apart from the detection switch 3 in the conveying direction of the conveying mechanism 2. The standby switch 4 is electrically connected to the controller, and is used to contact the glass 200 to detect the distance between two adjacent pieces of glass 200.

[0063] In this embodiment, in order to prevent the detection switch 3 from being damaged or malfunctioning, resulting in failure to detect, a backup switch 4 is provided in the coating chamber 13. Specifically, the backup switch 4 is provided downstream of the conveying mechanism 2 compared to the detection switch 3, that is, when the glass 200 is conveyed on the conveying mechanism 2, it first contacts the detection switch 3 and then contacts the backup switch 4. It can be understood that the function of the backup switch 4 is the same as that of the detection switch 3. At the same time, the connection direction of the backup switch 4 and the detection switch 3 can be set to be parallel to the conveying direction of the conveying mechanism 2, that is, the backup switch 4 and the detection switch 3 are in contact with the same position of the glass 200, so as to further improve the detection accuracy; of course, the backup switch 4 and the detection switch 3 can also be set to be staggered, that is, the backup switch 4 and the detection switch 3 respectively detect different positions of the glass 200, so as to obtain the distance between each part of the glass 200 and another piece of glass 200, so as to obtain the minimum distance between the two pieces of glass 200.

[0064] Based on the above control method of the glass coating system, after the step of comparing the spacing with the preset spacing, the method further includes:

[0065] When the standby switch detects the glass and detects that the glass is separated from the standby switch, the timing starts, and the timing ends when the standby switch continues to detect the next piece of glass, which is the second time length;

[0066] Acquire a conveying speed of the conveying mechanism, and calculate a second distance between the glass and the next glass according to the second time duration and the conveying speed;

[0067] The second spacing is compared with a preset spacing.

[0068] It can be understood that if the comparison result between the second spacing and the preset spacing is consistent with the detection result of the detection switch, it is judged that the detection switch and the backup switch are used normally. If not, the controller will issue an alarm to remind the equipment management personnel to conduct relevant inspections and handle them.

[0069] In one embodiment, the backup switches 4 include two, the two backup switches 4 are arranged at an interval, and the connection direction of the two backup switches 4 is arranged perpendicular to the conveying direction of the conveying mechanism 2 .

[0070] It is understandable that the two standby switches 4 correspond to the two detection switches 3. When the detection switch 3 cannot work normally, the two standby switches 4 can replace the detection switch 3 to continue to complete the detection work. The two standby switches 4 are respectively located on the opposite sides of the conveying direction of the conveying mechanism 2. When the glass 200 is conveyed on the conveying mechanism 2, the two standby switches 4 respectively detect the opposite sides of the glass 200, that is, the distance between the opposite sides of the glass 200 and the other glass 200 can be detected. It is understandable that the two standby switches 4 detect the distance between the glass 200 and the side with the smallest distance. In this way, when the glass 200 is tilted, one side is closer to the other glass 200 than the other side. The two standby switches 4 are set at intervals to more accurately determine the minimum distance between the two glasses 200, thereby effectively avoiding damage to the glass 200 caused by too small a distance.

[0071] In one embodiment, the conveying mechanism 2 includes a plurality of conveying rollers 21 . The plurality of conveying rollers 21 are disposed in the coating chamber 13 at intervals and arranged side by side. The detection switch 3 is disposed between two adjacent conveying rollers 21 .

[0072] It is understandable that the multiple conveying rollers 21 are arranged at intervals from each other and are in the same plane to smoothly convey the glass 200. Specifically, the multiple conveying rollers 21 are connected in transmission to ensure synchronous transmission, which can be through gear transmission or belt transmission, and a motor is connected to one end of a conveying roller 21 to provide driving force, and at the same time, the controller controls the motor to start and close. Further, a rubber ring is sleeved on the outer peripheral wall of the conveying roller 21 to contact and carry the glass 200. It is understandable that the rubber ring is made of soft rubber material, such as silicone or rubber, so as to facilitate the conveying of the glass 200 and avoid damage to the glass 200. At the same time, the detection switch 3 is arranged at the interval between two adjacent conveying rollers 21 to contact the glass 200 through the interval. Optionally, the standby switch 4 is arranged at the next interval of the interval. It is understandable that the interval between two adjacent conveying rollers 21 should be less than the length of the glass 200 in the conveying direction to prevent the glass 200 from falling into the interval during the conveying process.

[0073] In one embodiment, the glass coating system 100 further includes two supporting platforms 5, which are respectively disposed on opposite sides of the coating chamber 13, each supporting platform 5 is provided with a plurality of rotating grooves at intervals, one end of each conveying roller 21 is rotatably disposed in a rotating groove of one supporting platform 5, and the other end is rotatably disposed in a rotating groove of another supporting platform 5.

[0074] In this embodiment, the carrier 5 is in the shape of an elongated strip, and the two carriers 5 are arranged parallel to each other, and the length direction of each carrier 5 is arranged parallel to the conveying direction of the transmission mechanism. Optionally, a plurality of rotating grooves are provided on the side of each carrier 5 facing away from the bottom wall of the coating chamber 13, and the plurality of rotating grooves are arranged at intervals along the length direction of the carrier 5. It can be understood that each conveying roller 21 is rotatably arranged in a rotating groove to rotatably convey the glass 200. Optionally, the side of the carrier 5 facing away from the bottom wall of the coating chamber 13 is in a stepped shape to facilitate the installation of the conveying roller 21.

[0075] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
