The embodiment of the utility model provides a problem to the glass substrate piece that can't prevent and reduce the emergence among the prior art in the course of working, the utility model provides a atress detection device and production line.
The following describes in detail a specific implementation of the force detection device and the production line according to an embodiment of the present invention with reference to the accompanying drawings. The shapes and sizes of the structures in the drawings are not to scale, and are merely illustrative of the present invention.
An embodiment of the utility model provides a atress detection device, as shown in fig. 1, include: a detection substrate 101, a plurality of first pressure sensors 102, a signal collector 103, and a main control display (not shown in the figure); wherein,
each first pressure sensor 102 is respectively arranged on four sides of the detection substrate 101, and each first pressure sensor 102 is respectively connected with the signal collector 103 through an electric signal; the signal collector 103 is in electrical signal connection with the master control display;
the signal collector 103 is used for collecting stress information detected by each pressure sensor and sending the stress information detected by each pressure sensor to the main control display;
and the main control display is used for displaying the received stress information detected by each pressure sensor.
The embodiment of the utility model provides an among the above-mentioned atress detection device, can be through putting into the production facility in the production line with above-mentioned atress detection device, can detect the atress information that detects four sides of base plate 101 through first pressure sensor 102, and send the atress information that detects to the master control display through signal collector 103 and show, the engineer can be through the atress information that detects, judge whether too big with the pressure value that detects base plate 101's contact point department, and then the part of which positions of this equipment of analysis need the adjustment, thereby can be before glass substrate processing, adjust equipment in advance, the glass substrate that the prevention takes place in the reduction course of working is broken.
It should be noted that, the embodiment of the present invention refers to placing the stressed detection substrate into the production equipment, and refers to placing the detection substrate, the first pressure sensor on the setting and detection substrate, and the second pressure sensor mentioned subsequently into the production equipment, and the signal collector may be placed into the production equipment (for example, the signal collector is placed on the upper surface of the detection substrate) or not, and the main control display is not generally placed into the production equipment.
In practical applications, it is often necessary to align the glass substrate, for example, during the process of conveying the glass substrate between the apparatuses by the conveyor belt, the glass substrate needs to be aligned to make the glass substrate located at a specific position on the conveyor belt, or when the glass substrate arrives at a certain apparatus, the glass substrate needs to be aligned to make the glass substrate located at the center of the apparatus. In the alignment process, the glass substrate is aligned by the alignment mechanisms located on the periphery of the glass substrate, the alignment mechanisms located on two opposite sides of the glass substrate control the position of the glass substrate in one direction, for example, in a plan view of the glass substrate, the alignment mechanisms located on the left side and the right side of the glass substrate control the position of the glass substrate in the horizontal direction, and the alignment mechanisms located on the upper side and the lower side of the glass substrate control the position of the glass substrate in the vertical direction. The alignment mechanism is generally a rigid structure, and is driven to move by an air cylinder or a hydraulic cylinder so as to control the position of the alignment mechanism. With the continuous operation of the alignment mechanism, the precision of the alignment mechanism inevitably changes, or the alignment mechanism ages, so that the pressure applied to the glass substrate by the alignment mechanism has a certain deviation, for example, the pressures applied to the glass substrate by the left and right alignment mechanisms are inconsistent or too large, which may cause the glass substrate to be broken.
By respectively arranging the first pressure sensors 102 on the four sides of the detection substrate 101, when the detection substrate 101 is in contact with the alignment mechanism, the alignment mechanism applies force information to the detection substrate 101, and an engineer can determine whether the corresponding alignment mechanism needs to be adjusted according to the force information.
When the specific implementation is performed, each first pressure sensor 102 and the signal collector 103 are electrically connected, and may be wirelessly connected, and may also be wired, and preferably are wirelessly connected, so that the problem of wiring of the connecting wires does not need to be considered. Similarly, the signal collector 103 and the main control display are preferably connected in a wireless manner, but may also be connected in a wired manner, which is not limited herein.
Specifically, the first pressure sensor 102 may be a lightweight and thin pressure sensor, and may be any kind of pressure sensor, such as a ceramic pressure sensor, a piezoresistive pressure sensor, an inductive pressure sensor, a capacitive pressure sensor, or the like.

The main control display may be any display with a display function, such as a liquid crystal display.

Of course, in a special case, a component (e.g., an alignment mechanism) in the apparatus can only contact with a specific position of the detection substrate 101, and as shown in fig. 2, the first pressure sensor 102 may be disposed so as not to cover the entire side.
In practical application, when the devices in the production line have different heights, the glass substrate needs to be taken off from the conveyor belt through the mechanical arm, placed on the plurality of ejector rods extending out of the devices, moved to be placed at a proper position through the plurality of ejector rods, jacked up through the plurality of ejector rods after the processing of the glass substrate is completed, moved to the position where the mechanical arm takes the glass substrate, and placed on the conveyor belt through the mechanical arm to be conveyed to the next device. Because the number of the ejector rods is large, the situation of asynchronism among the ejector rods can inevitably occur in the working process of equipment, so that the stress of the glass substrate positioned on the ejector rods is uneven, and when the pressure at a certain position is overlarge, the glass substrate can be broken.
Based on the above situation, the embodiment of the utility model provides an above-mentioned atress detection device can also include: and a second pressure sensor 104 disposed on the bottom surface of the detection substrate 101.

Specifically, the embodiment of the present invention provides an above-mentioned stress detection device, in order to make the detected stress information closer to the stress condition of the substrate to be processed (glass substrate), the above-mentioned detection substrate 101 is preferably matched with the size and weight of the substrate to be processed. Here, "matching" may mean that the size and weight of the detection substrate 101 and the substrate to be processed are equal, and there may be a certain deviation in practical application, for example, the error may be within a range of ± 5%.
In actual production, the processing substrate used is generally a glass substrate, and therefore, the detection substrate 101 is preferably a glass substrate, but of course, the detection substrate 101 may be made of other materials, and is not limited thereto.
Further, the embodiment of the utility model provides an among the above-mentioned atress detection device that provides, the master control display still is used for:
and when the pressure value in the received stress information is greater than a preset threshold value, sending alarm information.
