Description
Technical Field
[0001] The present disclosure relates to the technical field of glass dust collection, and in particular, to a glass dust collection device and a glass substrate production line. Background Art
[0002] In the production of optoelectronic display glass substrates (such as OLED and LTPS glass substrates produced by the overflow down-pull method, and ultra-thin flexible glass substrates with a thickness of less than 0.1 mm, etc.), glass substrates usually need to be grabbed by a plate-taking robot from one station and placed in another station. For example, after the glass substrate is cut by a cross-cutting machine, it will be grabbed by a plate-taking robot and transferred to a conveyor belt. Since the glass substrate is thin, it may fall off the gripper of the plate-taking robot and hit the ground due to the plate-taking robot's loose grip. The broken glass substrate is likely to produce a large amount of fine glass dust floating in the air, which will contaminate other glass substrates in the production process.
[0003] In the related art, glass dust generated by broken glass substrates is generally cleaned manually by sprinkling water on the falling place of the glass substrate to reduce dust. On the one hand, the cleaning process will cause the production line to stop for a long time, delaying production, and on the other hand, there is a risk of injury to the cleaning personnel. Utility Model Content
[0004] The purpose of the present disclosure is to provide a glass dust collection device and a glass substrate production line to solve the above technical problems.
[0005] In order to achieve the above-mentioned object, as a first aspect of the present disclosure, the present disclosure provides a glass dust collection device, comprising a dust box, the dust box is used to be arranged between a first station and a second station, and is located below a moving path of a gripper of a plate-taking robot from the first station to the second station, so that a glass substrate falling off the gripper can fall onto the dust box;
[0006] A cavity is formed in the dust box, and a suction hole and a discharge hole are formed on the dust box. The suction hole and the discharge hole are both connected to the cavity. The discharge hole is used to connect a negative pressure device. There are multiple suction holes, and the multiple suction holes are distributed on the upper surface of the dust box. The suction holes are used to allow glass dust to enter the cavity.
[0007] Optionally, a recessed portion is provided on the side of the dust collecting box, and the recessed portion is used to accommodate a frame of the plate-removing robot.
[0008] Optionally, the dust collecting box includes a first box body and two second box bodies, the first box body is located between the two second box bodies, and the two second box bodies and the first box body together enclose the recessed portion.
[0009] Optionally, there are a plurality of cavities, the plurality of cavities are not interconnected, and each of the cavities corresponds to the discharge hole and the suction hole.
[0010] Optionally, the glass dust collection device further comprises a position detector, which is used to detect a drop position of the glass substrate on the dust collecting box, so that the cavity corresponding to the drop position can generate negative pressure.
[0011] Optionally, the position detector comprises an infrared position detector, which is arranged above the dust box, and each of the cavities is correspondingly provided with at least one infrared position detector;
[0012] The infrared position detector comprises an infrared transmitter and an infrared receiver which are arranged opposite to each other. The infrared transmitter is used to transmit infrared light, and the infrared receiver is used to receive the infrared light transmitted by the infrared transmitter.

DETAILED DESCRIPTION
[0026] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0027] In the present disclosure, unless otherwise stated, the directional words used, such as "upper" and "lower", are usually defined based on the drawing direction of the corresponding drawings. They are only for the convenience of describing the present disclosure and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, specific orientation structure and operation, and therefore cannot be understood as limiting the present disclosure. "Inside" and "outside" refer to the inside and outside of the contour of the corresponding component. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0028] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.
[0029] As a first aspect of the present disclosure, Figures 1 to 3 As shown, the present disclosure provides a glass dust collection device, including a dust box 1, which is used to be arranged between a first station 10 and a second station 20, and is located below the moving path of a gripper of a plate-taking robot 30 from the first station 10 to the second station 20, so that a glass substrate 200 falling off the gripper can fall onto the dust box 1.
[0030] A cavity is formed in the dust box 1. A suction hole 11 and a discharge hole 12 are formed on the dust box 1. Both the suction hole 11 and the discharge hole 12 are connected to the cavity. The discharge hole 12 is used to connect a negative pressure device. There are multiple suction holes 11, which are distributed on the upper surface of the dust box 1. The suction holes 11 are used to allow glass dust to enter the cavity.
[0031] Through the above technical solution, since the dust box 1 is used to be set between the first station 10 and the second station 20, and the gripper of the plate-taking robot 30 is located below the moving path from the first station 10 to the second station 20, if the glass substrate 200 falls off the gripper, the glass substrate 200 can directly fall on the upper surface of the dust box 1, and the upper surface of the dust box 1 is provided with a plurality of suction holes 11, and the suction holes 11 are connected to the discharge holes 12 through the cavity, and the discharge holes 12 are further connected to the negative pressure device, so the broken glass substrate 200 and the resulting glass dust can be sucked into the cavity through the suction holes 11, and discharged from the cavity through the discharge holes 12. Such a setting, on the one hand, can improve the convenience and cleaning efficiency of glass dust cleaning, and the dust box 1 can clean the glass dust on site faster, thereby shortening the cleaning time and shortening the delay time of the production line; on the other hand, it can also avoid the risk of personal injury caused by manual cleaning.
[0032] It should be noted that the first station 10 and the second station 20 can be stations on any glass production line. For example, the first station 10 can be a glass cutting station, and the second station can be a glass conveying station. The plate-taking robot 30 is used to transfer the glass substrate cut by the glass cutting station to the glass conveying station. Alternatively, the first station 10 can also be a glass conveying station, and the second station 20 can be a glass packaging station. The present disclosure does not limit the specific arrangement of the dust box 1 between the first station 10 and the second station 20.
[0033] Alternatively, if Figure 1 and Figure 2 As shown, a recessed portion 13 is provided on the side of the dust box 1, and the recessed portion 13 is used to accommodate the frame of the plate-taking robot 30. The gripper of the plate-taking robot 30 is rotatably mounted on the frame of the plate-taking robot 30. By providing the recessed portion 13 for accommodating the plate-taking robot 30 on the side of the dust box 1, the frame can be surrounded by the dust box 1, so that the lower part of the moving path of the gripper installed on the frame can be covered by the dust box 1, thereby ensuring that the dropped glass substrate 200 can be located within the coverage of the dust box 1, thereby improving the convenience of cleaning the glass dust.
[0034] The present disclosure does not limit the specific structure of the dust box 1. In one embodiment of the present disclosure, Figure 1 and Figure 2 As shown, the dust box 1 includes a first box body 14 and two second boxes 15, the first box body 14 is located between the two second boxes 15, and the two second boxes 15 and the first box body 14 together enclose a recessed portion 13. The recessed portion 13 enclosed by the two second boxes 15 and the first box body 14 reduces the processing difficulty and installation cost of the dust box 1.
[0035] To improve the cleaning effect, optionally, Figure 1 and Figure 2 As shown, there are multiple cavities, which are not connected to each other, and each cavity corresponds to a discharge hole 12 and a suction hole 11. Since the discharge hole 12 is connected to the cavity and the discharge hole 12 is used to connect the negative pressure device, corresponding discharge holes 12 are set on the multiple cavities, so that the negative pressure generated in each cavity is independent of each other, thereby improving the suction force of a single cavity to collect glass dust, and further improving the collection and cleaning efficiency of the collection device for glass dust.
[0036] In one embodiment provided by the present disclosure, Figure 1 and Figure 2As shown, the dust box 1 includes a plurality of independent boxes 16, which are assembled with each other, each box 16 has a cavity formed therein, the cavities in the plurality of boxes 16 are not interconnected, and each box 16 has a suction hole 11 and a discharge hole 12 formed therein. On the one hand, by using a plurality of independent boxes 16 and providing an independent cavity, discharge hole 12 and suction hole 11 in each box 16, the negative pressure in the cavity of each box 16 is more concentrated, and will not be dispersed because the plurality of boxes 16 are interconnected.
[0037] On the other hand, since the dust box 1 is used to be arranged between the first workstation 10 and the second workstation 20, in actual production, the ground space between the first workstation 10 and the second workstation 20 may be different due to the equipment layout on site. The multiple boxes 16 are arranged in a splicing manner and can be spliced according to the actual situation on site, thereby making the arrangement of the dust box 1 more flexible to adapt to different on-site conditions.
[0038] It is understandable that the plurality of independent boxes 16 may include the first box 14 and the second box 15 described above.
[0039] In order to improve the automation level of the glass dust collection device, optionally, as Figure 1 and Figure 3 As shown, the glass dust collection device also includes a position detector, which is used to detect the falling position of the glass substrate 200 on the dust box 1, so that the cavity corresponding to the falling position can generate negative pressure. Since a plurality of cavities that are not connected to each other are arranged in the dust box 1, and each cavity is correspondingly provided with a suction hole 11 and a discharge hole 12, when the glass substrate 200 falls, the falling position of the glass substrate 200 can be detected by the position detector, and the cavity corresponding to the falling position can be started to collect glass dust, while other cavities do not work. On the one hand, it can save energy and perform fixed-point cleaning. On the other hand, it can also improve the degree of automation of the glass dust collection device, speed up the response speed of the collection device, and improve the cleaning efficiency.
[0040] Alternatively, if Figure 1 and Figure 3As shown, the position detector includes an infrared position detector 2, which is arranged above the dust box 1, and each cavity is correspondingly provided with at least one infrared position detector 2. The infrared position detector 2 includes an infrared transmitter 21 and an infrared receiver 22 arranged relatively to each other, the infrared transmitter 21 is used to emit infrared light 23, and the infrared receiver 22 is used to receive the infrared light 23 emitted by the infrared transmitter 21. When the glass substrate 200 falls, due to the obstruction of the glass substrate 200, the light emitted by the infrared transmitter 21 cannot be completely received by the infrared receiver 22 (because the refraction and / or reflection of the glass weakens the infrared intensity), and the infrared position detector 2 thus knows which cavity above which the infrared light 23 is intercepted, thereby knowing the falling position of the glass substrate 200. By using the infrared position detector 2, the falling position of the glass substrate 200 can be detected without affecting the normal operation of the dust collection device, thereby improving the degree of automation of the dust collection device.
[0041] In other embodiments, the position detector may also include a laser position detector or a camera.
[0042] Alternatively, if Figure 1 and Figure 3 As shown, the glass dust collection device further includes a first mounting bracket 3 and a second mounting bracket 4, the first mounting bracket 3 and the second mounting bracket 4 are arranged opposite to each other, and the dust collection box 1 is located between the first mounting bracket 3 and the second mounting bracket 4. The infrared transmitter 21 is mounted on the first mounting bracket 3, and the infrared receiver 22 is mounted on the second mounting bracket 4.
[0043] It should be noted that if Figure 1 and Figure 3 As shown, for the infrared transmitter 21 facing the frame of the plate-taking robot, its corresponding infrared receiver can be installed on the frame.
[0044] Optionally, in one embodiment provided by the present disclosure, the glass dust collection device further includes a controller, which is electrically connected to the position detector. The discharge holes 12 of the plurality of cavities are all connected to the same negative pressure device through a switch valve, and the controller is electrically connected to the switch valve. The controller is used to control the switch valve corresponding to the cavity corresponding to the drop position to open according to the drop position of the glass substrate 200 on the dust box 1 detected by the position detector. The discharge holes 12 of each cavity are connected to the same negative pressure device through their own switch valves. After the controller receives a signal from the position detector, it sends a signal to the switch valve of the cavity corresponding to the drop position, connecting the cavity with the negative pressure device, thereby cleaning the glass dust.
[0045] Optionally, the switch valve may be a solenoid switch valve.
[0046] In another embodiment provided in the present disclosure, there may be multiple negative pressure devices, the exhaust hole 12 of each cavity is connected to the corresponding negative pressure device, each negative pressure device provides negative pressure for an independent cavity, and the controller is electrically connected to the negative pressure device. The controller is used to control the negative pressure device corresponding to the cavity corresponding to the falling position of the glass substrate 200 on the dust box 1 detected by the position detector to turn on.
[0047] As a second aspect provided by the present disclosure, the present disclosure provides a glass substrate production line 100, including a first workstation 10, a second workstation 20, a plate-taking robot 30 and the above-mentioned glass dust collection device, the gripper of the plate-taking robot 30 is used to grab the glass substrate 200 at the first workstation 10 and place it on the second workstation 20, the dust box 1 of the glass dust collection device is arranged between the first workstation 10 and the second workstation 20, and is located below the moving path of the gripper of the plate-taking robot 30 from the first workstation 10 to the second workstation 20.
[0048] Optionally, the first station 10 is a glass cutting station, and the second station 20 is a glass conveying station.
[0049] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0050] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0051] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
