In the actual process of human operation, the distance of the gap is usually adjusted to meet the requirements of operation accuracy and the like. In the processing of TFT arrays, for example in thin film transistor liquid crystal display (Thin Film Transistor-Liquid CrystalDisplay, TFT-LCD) technology, it is often necessary to provide a suitable gap for the glass substrate that is reserved by the equipment that prevents the glass substrate from slipping.
The TFT-LCD technology is to use micro-electronic fine processing technology on silicon (si), transplant the technology to a large-area glass substrate to process a TFT array, then use the array substrate and another substrate with color filter film to form a liquid crystal box by combining with the already mature LCD technology, and finally form a liquid crystal display through post procedures such as polaroid pasting and the like. Wherein the following steps are generally employed in the fabrication of the TFT array: firstly, a thin film, a non-conductive layer and a semiconductor layer are sequentially plated on a clean glass substrate, then a transistor pattern is manufactured, and then wet etching is performed.
In order to prevent the glass substrate from slipping in the chemical solution and water during the wet etching process, a roller device as shown in fig. 1 is arranged in a tank containing the chemical solution and water, and the roller device comprises a first roller unit 10 and a second roller unit 11 which are oppositely arranged, wherein the first roller unit 10 can move relative to the second roller unit 11 so as to reserve a proper gap 12 between the first roller unit and the second roller unit, so that the glass substrate can be placed between the first roller unit and the second roller unit, and the glass substrate can be prevented from slipping. It should be appreciated that if the gap 12 is too large, the purpose of preventing the glass substrate from slipping cannot be achieved; if the gap 12 is too small, breakage of the glass substrate may occur. Thus, a more accurate reservation of the required gap 12 is required.
Currently, a thick gauge (i.e., a feeler gauge or a gap piece) is basically used for adjusting the gap. The existing thickness gauge consists of a group of thin steel sheets with different thickness difference levels, and the adjustment is judged by an inspector according to the degree of tightness of the matching of the thickness gauge and the measured surface. However, this may result in inaccurate adjustment of the gap due to the different judgment criteria for each individual. In addition, after the roller device is used for a long time, the deformation phenomenon of the roller can possibly occur, and the existing thickness gauge can not judge the deformation phenomenon.

Detailed Description
The following describes specific embodiments of the present invention in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the invention, are not intended to limit the invention.
In the present invention, unless otherwise indicated, terms of orientation such as "upper, lower, left, right" and the like are used generally to refer to directions understood in conjunction with the actual directions of application or directions shown in the drawings.
Fig. 1 shows a conventional roller device comprising a first roller unit 10 and a second roller unit 11 disposed opposite to each other, the first roller unit 10 comprising a first roller 100 and a first roller 101 fitted around the first roller 100, the second roller unit 11 comprising a second roller 110 disposed parallel to the first roller 100 and a second roller 111 fitted around the second roller 110, the first roller unit 10 being movable relative to the second roller unit 11 to form a gap 12 therebetween, as oriented in fig. 1, the first roller unit 10 being movable upward relative to the second roller unit 11 to form a gap 12 therebetween, and a glass substrate being transferred in the formed gap 12.
The invention provides a gap adjusting device comprising a sensing piece 20 with a thickness t, the sensing piece 20 being capable of being placed in a gap to be adjusted and capable of sensing a force applied against the sensing piece 20 forming the gap, the gap adjusting device further comprising a display mechanism 21 electrically connected to the sensing piece 20 and displaying the sensing result of the sensing piece 20. Through setting up the sensing piece 20 that can respond to whether atress and with this sensing piece 20 electricity be connected and show the display mechanism 21 of the response result of sensing piece 20, can accurately adjust out the size of required clearance, compare and select the thickness gauge to adjust, improved the adjustment precision greatly.
The above gap adjusting device can be applied to various fields, for example, the roller device selected in the wet etching process to accurately adjust the gap 12 formed between the first roller unit 10 and the second roller unit 11 (i.e. the gap formed between the first roller 101 and the second roller 111), so as to prevent the glass substrate conveyed in the gap 12 from slipping, and prevent the film on the glass substrate from being scratched and the glass substrate from being crushed, and the structure of the roller device is described in the above description and will not be repeated here. The process of specifically adjusting the gap 12 formed between the first roller unit 10 and the second roller unit 11 is as follows: placing the sensing piece 20 with the thickness t in the gap 12 and making the display mechanism 21 not display the numerical value, it is understood that when the sensing piece 20 is placed in the gap 12, the non-sensing stressed surface of the sensing piece 20 can be made to lean against the second roller unit 11, and meanwhile, the first roller unit 10 is moved upwards by a larger distance so that the sensing piece 20 is easily located between the two, and the first roller unit 10 cannot touch the sensing piece 20; then, the first roller unit 10 is moved towards the sensing piece 20, so that the sensing piece 20 is stressed and the display mechanism 21 displays the numerical value, and at this time, the first roller unit 10 can only partially contact the sensing piece 20 or can be completely pressed on the sensing piece 20, so long as the display mechanism 21 displays the numerical value; then, the first roller unit 10 is gradually moved upward until the display mechanism 21 just displays no value, which indicates that the sensing piece 20 is just not stressed, and thus the size of the gap 12 formed between the first roller unit 10 and the second roller unit 11 is accurately adjusted, that is, the gap capable of allowing the glass substrate to pass without being damaged is adjusted. It will be appreciated that the thickness t of the sensing piece 20 is known prior to adjustment, and more specifically, the thickness of the portion of the sensing piece 20 that is capable of sensing whether a force is applied is equal to the distance of the desired gap, which facilitates adjustment of the desired gap 12, and the thickness t of the sensing piece 20 can be set according to the actual desired gap reserved for the glass substrate. The thickness t of the sensing piece 20 is preferably 0.1-1mm, and further, the thickness t is preferably 0.2-0.3mm.
As shown in fig. 2-3, the display mechanism 21 includes a body 210 and a display 211 mounted on the body 210. In addition, the outer surface of the body 210 can be provided with a mounting hole 212, and the sensing piece 20 is inserted into the mounting hole 212 to realize detachable connection of the sensing piece 20 and the body 210, so that the sensing pieces 20 with different thicknesses can be mounted on the same display mechanism 21 to meet the requirements of adjusting different gaps, thereby not only reducing the cost, but also being convenient to use. In the process of preparing a plurality of induction pieces 20 with different thicknesses, the thickness of one end of each induction piece 20 inserted into the corresponding mounting hole 212 can be set to be the same, so that the induction pieces 20 can be conveniently connected with the mounting holes 212, and the induction pieces 20 can be conveniently replaced.
In addition, as shown in fig. 4, the sensing piece 20 preferably includes a substrate 200 and a force-sensitive resistor 201 located on one surface of the substrate 200, the force-sensitive resistor 201 being connected to a display 211, since the force-sensitive resistor 201 is provided on only one surface of the substrate 200, when the gap 12 adjustment operation is performed, one surface of the substrate 200 on which the force-sensitive resistor 201 is not provided needs to be abutted against one surface forming the gap 12, and the surface of the substrate 200 on which the force-sensitive resistor 201 is provided faces the other surface forming the gap 12, the display 211 displays a value when the force-sensitive resistor 201 is subjected to the force exerted by the surface; when the force sensitive resistor 201 does not sense any force, the display 211 does not display any value. Preferably, the force sensitive resistor 201 and the display mechanism 21 are connected by a metal lead 202, more specifically, the metal lead 202 is electrically connected to the display mechanism 21 by providing a metal contact 216 at the mounting hole 212. The material of the substrate 200 may be a resin, and the specific type of the resin may be selected according to the actual requirements, and is not particularly limited. The force sensor 201 may be of various kinds, for example, selenium tellurium alloy force sensor may be preferable to improve the sensitivity of sensing, but the force sensor 201 may be of other kinds as well, and is not limited to the above kind.
In order to effectively protect the force-sensitive resistor 201, as shown in fig. 5, a protective layer 203 may be further disposed on the substrate 200, where the protective layer 203 at least covers the force-sensitive resistor 201 and the metal lead 202, so as to effectively prevent the sensing piece 20 from being corroded by pollutants such as a liquid medicine, and greatly improve the service life of the sensing piece 20. As for the material of the protective layer 203, resin may be selected, and in practical application, the specific type of resin may be selected completely according to practical requirements.
Further, the gap adjusting device may be provided therein with a detection circuit for detecting whether the sensing piece 20 is stressed, as shown in fig. 6, which may include a bridge circuit 213 having an input terminal connected to a power source, an amplifier 214 connected to an output terminal of the bridge circuit 213, a DA converter 215 connected to an output terminal of the amplifier 214, and a display 211 connected to the DA converter 215, wherein: the bridge circuit 213 includes a force sensing resistor 201, a first fixed resistor 2130, a second fixed resistor 2131, and a third fixed resistor 2132, wherein the force sensing resistor 201, the first fixed resistor 2130, the second fixed resistor 2131, and the third fixed resistor 2132 form four bridge arms, respectively, and one diagonal of the bridge circuit 213 is used as the input terminal, and the other diagonal is used as the output terminal. The resistance values of the force sensitive resistor 201, the first fixed resistor 2130, the second fixed resistor 2131 and the third fixed resistor 2132 are sequentially recorded as R 0、R1、R2、R3, when the force sensitive resistor 201 is not stressed, the bridge circuit 213 reaches an equilibrium state, namely R 0+R1＝R2+R3, and innumerable values are displayed on the display 211; when the force sensing resistor 201 receives a certain force, the resistance value changes, the bridge circuit 213 loses balance, and at this time, a signal voltage is outputted, amplified by the amplifier 214 and transmitted to the DA converter 215, and finally the display 211 displays the value.
The invention also provides a roller clearance adjustment method, wherein the roller comprises a first roller unit 10 and a second roller unit 11 which are oppositely arranged, the first roller unit 10 can move relative to the second roller unit 11 to form a clearance 12 between the first roller unit and the second roller unit, and the roller clearance adjustment method comprises the following two steps:
step S11, placing the sensing piece 20 with the thickness t in the gap 12, so that the sensing piece 20 is not subjected to the force applied by the surface forming the gap 12 and the sensing piece 20 does not generate induction, and then moving the first roller unit 10 towards the sensing piece 20, so that the sensing piece 20 is stressed and generates induction;
In step S12, after the sensing piece 20 is stressed and senses, the first roller unit 10 is gradually moved until the sensing piece 20 is just not sensed, and then the sensing piece 20 is taken out.
In the above step S11, the structure of the roller is as shown in fig. 1. When the sensing piece 20 is put into the gap 12 formed between the first roller unit 10 and the second roller unit 11, the surface of the sensing piece 20 opposite to the surface capable of sensing force is abutted against the second roller unit 11 (precisely, abutted against the second roller 111), that is, the surface of the sensing piece 20, on which the force-sensitive resistor 201 is not provided, is abutted against the second roller unit 11, and at the same time, the first roller unit 10 is moved upward by a large distance so that the sensing piece 20 is easily located between the two, so that the first roller unit 10 cannot touch the sensing piece 20, at the same time, the sensing piece 20 is not subjected to the force applied by the surface forming the gap 12, and at the same time, no sensing is generated, and it can be understood that when the gap adjusting device provided by the present invention is selected, the display mechanism 21 electrically connected with the sensing piece 20 does not display any numerical value, and then the first roller unit 10 is moved toward the sensing piece 20, that is moved downward, at the time, so that the sensing piece 20 is easily located between the two, the sensing piece 20, the force-sensitive resistor 201 displays the numerical value due to the force-sensitive resistor 201. In moving the first roller unit 10, the first roller unit 10 may only partially contact the sensing piece 20, or may be completely pressed against the sensing piece 20, so long as the display mechanism 21 displays a numerical value.
In the above step S12, after step S11 is completed, the first roller unit 10 is gradually moved up until the sensing piece 20 is just not sensed, and it is understood that when the gap adjustment device provided by the present invention is used for roller gap adjustment, the display mechanism 21 just does not display a numerical value, so that the gap 12 required to be formed between the first roller unit 10 and the second roller unit 11 is accurately adjusted, that is, the gap capable of allowing the glass substrate to pass through without being damaged is adjusted. It will be appreciated that the thickness t of the sensing piece 20 is known prior to adjustment, and more specifically, the thickness of the portion of the sensing piece 20 that is capable of sensing whether a force is applied is equal to the distance of the required gap, so that the required gap 12 can be adjusted, and in addition, the thickness t of the sensing piece 20 can be set according to the gap that is actually required to be reserved for the glass substrate. The thickness t of the sensing piece 20 is preferably 0.1-1mm, and further, the thickness t is preferably 0.2-0.3mm.
By using the roller clearance adjustment method provided by the invention, the clearance required to be reserved for the glass substrate in the roller can be accurately adjusted, so that the glass substrate does not slip in the conveying process, and the glass substrate is not damaged by the force applied by the surface forming the clearance.
The present invention also provides a method for detecting roller deformation of a roller device, wherein the roller device comprises a first roller unit 10 and a second roller unit 11 which are oppositely arranged, the first roller unit 10 comprises a first roller 100 and a first roller 101 sleeved on the first roller 100, the second roller unit 11 comprises a second roller 110 which is arranged in parallel with the first roller 100 and a second roller 111 sleeved on the second roller 110, the first roller unit 10 can move relative to the second roller unit 11 to form a gap 12 between the first roller unit and the second roller unit, and the method for detecting roller deformation of the roller device comprises the following two steps:
step S21, placing the sensing piece 20 in the gap 12 corresponding to the sensing piece 20,
Step S22, the sensing piece 20 is kept still, so that the first roller 101 and the second roller 111 rotate, and when the display mechanism 21 displays innumerable values, no deformation of the rollers is indicated.
In the above step S21, the sensing piece 20 is placed in the gap 12 corresponding to the sensing piece 20, that is, the sensing piece 20 needs to be placed in the gap 12 already reserved for the glass substrate to be passed, wherein the gap 12 corresponding to the sensing piece 20 is preferably adjusted by the following method: placing the sensor sheet 20 of thickness t in the gap 12 and causing the display means 21 not to display a value, preferably causing the non-force-inducing side of the sensor sheet 20 to rest against the second roller unit 11 when the sensor sheet 20 is placed in the gap 12, and thereafter moving the first roller unit 10 toward the sensor sheet 20 so that the sensor sheet 20 is forced and causing the display means 21 to display a value; then, the first roller unit 10 is gradually moved until the display mechanism 21 just does not display the numerical value, and at this time, the gap formed between the first roller 101 and the second roller 111 is the gap 12 corresponding to the sensing piece 20. The method for adjusting the gap is mentioned in the foregoing, and will not be described in detail here.
In the above step S22, the sensing piece 20 is kept stationary, so that the roller rotates, and if the display mechanism 21 displays numerous values all the time during the rotation of the roller, it indicates that the roller is not deformed.
In addition, when the display mechanism 21 displays a numerical value, the first roller unit 10 is moved to enable the first roller 101 to be fully pressed on the sensing piece 20, and enable the first roller 101 to rotate, and at the moment, when the numerical value displayed by the display mechanism 21 fluctuates within a preset range, no deformation of the roller can be indicated. Wherein the preset range is-30% -30% of the value displayed by the display mechanism 21 when the first roller 101 is fully pressed against the sensing piece 20, i.e. when the preset range fluctuates, it indicates that the roller is not deformed. When the fluctuation range of the numerical value displayed on the display mechanism 21 is larger, that is, when the fluctuation range of the numerical value is not within the preset range, the roller is deformed, the roller can be replaced, preferably the first roller 101 capable of moving up and down is replaced, after the first roller 101 is replaced, the roller deformation detection method of the roller device provided by the invention is continuously selected for detection, in the detection process, if the fluctuation range of the numerical value displayed on the display mechanism 21 is within the preset range, the roller device is put into use, and if the fluctuation range of the numerical value displayed on the display mechanism 21 is not within the preset range, the relatively fixed second roller 111 is required to be replaced.
By utilizing the method for detecting the deformation of the roller device, whether the roller in the roller device is deformed or not can be accurately judged, so that the deformed roller is replaced in time, the glass substrate is ensured to be conveyed safely and efficiently, and the reliability and the production efficiency of the conveyed glass substrate are greatly improved.
