Description

Ceramic wafer inclination positioning device and application method thereof

Technical Field

The invention relates to the field of automatic equipment manufacturing, in particular to a ceramic wafer inclination positioning device and a using method thereof.

Background

In the preparation process of ceramic sheets, such as membrane sheets used in fuel cells, the ceramic sheets are usually required to be produced through the processes of grabbing, stacking, pressing and the like by a mechanism, but before the processes, the ceramic sheets are positioned on a transfer mechanism at different positions, which causes great uncertainty to the subsequent preparation process, so that the ceramic sheets produced in the previous process are required to be subjected to position adjustment and placed at proper and consistent angles.

In the prior art, the adjustment of the position of the incoming material can be carried out by adopting a camera to take an image visually and then by adopting an X/Y/theta adjusting mechanism, but the obtained pressing block can be corrected later in the production process of ceramic sheets like diaphragm sheets and the like, and the positioning of ultra-high precision is not needed, so that the existing visual three-dimensional adjusting mechanism is used, the cost is higher, the mechanism is complex, more space of a production line is occupied, and the adoption of the existing visual three-dimensional adjusting mechanism is inconvenient in the practical application process.

Disclosure of Invention

The invention aims to provide a ceramic wafer inclination positioning device and a use method thereof, which are used for solving one or more technical problems in the prior art and at least providing a beneficial selection or creation condition.

The technical scheme adopted for solving the technical problems is as follows:

the invention provides a ceramic wafer inclination positioning device which comprises a fixed support, a movable flat plate and an adjustment driving structure, wherein the movable flat plate is rotatably arranged on the fixed support around a transversely extending axis, a first positioning edge and a second positioning edge are arranged on the movable flat plate, and an included angle is formed between the first positioning edge and the second positioning edge; the adjusting driving structure drives the movable flat plate to rotate on the fixed support; the plurality of position sensors are arranged on the movable flat plate.

The beneficial effects of the invention are as follows:

the ceramic plate is placed on the movable flat plate, the driving structure is adjusted to drive the movable flat plate to rotate, so that the ceramic plate moves obliquely, the adjacent edges are positioned between the included angles formed by the first positioning edge and the second positioning edge, and the position sensor is used for detecting whether the ceramic plate is positioned in place or not. Through the slope location, simple structure, the space occupies less, and the location is quick.

As a further improvement of the technical scheme, the adjusting driving structure comprises a driving seat and a driving unit, a follower wheel is arranged at the bottom of the movable flat plate, an eccentric wheel is arranged at the output end of the driving unit, an elastic piece is arranged between the driving seat and the bottom of the movable flat plate, and the elastic piece has elastic force enabling the follower wheel to be tightly attached to the eccentric wheel.

As a further improvement of the technical scheme, the movable flat plate is provided with a first positioning plate and a second positioning plate in an adjustable mode, the first positioning plate and the movable flat plate form a first positioning edge, and the second positioning plate and the movable flat plate form a second positioning edge.

As a further improvement of the above technical solution, the included angle is a right angle. Matching the shape of the positioning diaphragm.

As a further improvement of the technical scheme, the movable flat plate is also provided with air holes. The method is well positioned by the combination of oblique positioning, positive pressure blowing of air holes and switching of negative pressure adsorption.

As a further improvement of the above technical scheme, the area of the movable flat plate positioning ceramic plate is divided into an open area and an area without air holes, and the area without air holes comprises: the intersection point of the included angles is an isosceles triangle area with the right-angle side L at the point p 0; the area of the ceramic sheet is positioned in the area with the boundary width of the area S0 being a, wherein the area s1= (50% -60%) of the open pore area s0 and the area shole= (0.001% -0.002%) of the open pore area shole= (S1).

The edge non-perforated area is arranged to prevent gas from escaping, if a is smaller than 8mm, gas can escape rapidly, and if a is larger than 15mm, the perforated area is reduced, and the air floatation effect of platform blowing on the ceramic plate is reduced, so that the positioning efficiency is affected.

The area S1 of the open area should not be lower than 50% of the area S0 of the area occupied by the ceramic sheet after the ceramic sheet is positioned theoretically, if the area S1 of the open area is lower than 50% of the area S0 of the area occupied by the ceramic sheet, the air floating effect of the air blowing of the platform air hole on the ceramic sheet is affected, meanwhile, the vacuum adsorption effect is poor after the positioning is completed, the ceramic sheet is offset again after the platform is lifted, the subsequent production process is affected, and if the area S1 of the open area is higher than 60%, the probability that two sides of the ceramic sheet exceed the first positioning side and the second positioning side is increased. The open pore area S pore also has this effect.

As a further improvement of the above technical scheme, l=60 mm to 70mm, a=8 mm to 15mm. If L is smaller than 60mm, namely the open area is too large, the ceramic plate is easily blown up to be close to the right-angle positioning part, so that the ceramic plate is separated from the platform, and if L is larger than 70mm, namely the open area is too small, the effect of air floatation of the right-angle positioning part is insufficient, and the sliding time of the ceramic plate is prolonged.

The detection effect is better through setting up position sensor. When the edge of the ceramic plate is wrinkled and exceeds the positioning edge and is lapped on the first positioning plate and/or the second positioning plate or the angle of the ceramic plate deviates by more than 0.15 degrees after the ceramic plate is positioned, the reflected light quantity of the first position sensor, the second position sensor and the third position sensor changes, so that the ceramic plate is detected to be well unset and alarm; wherein the fourth sensor is provided for detecting whether the movable plate has a ceramic sheet thereon.

The invention also provides a using method of the ceramic wafer inclination positioning device, which comprises the following steps:

placing the ceramic sheet product before sintering on a movable flat plate;

the adjusting driving structure drives the movable flat plate to rotate to a certain angle clockwise around a transversely extending axis, so that the ceramic plate slides up and down to be contacted with the first positioning edge and the second positioning edge on the inclined movable flat plate, and simultaneously air is blown to air holes on the movable flat plate in the descending process;

when the movable flat plate is positioned at the position of the maximum inclination angle, the position sensor detects, if the ceramic plate is detected to be positioned on the movable flat plate, the alarm is given, and if the ceramic plate is detected to be positioned on the movable flat plate, the air hole on the movable flat plate is switched to negative pressure adsorption;

The rotation position of the movable flat plate 200 and the following mounting seat 240 are located on the bisector of the included angle, so that the driving structure has the effect of better tilting the movable flat plate 200, and the rotation angle of the movable flat plate 200 is better controlled. In other embodiments, the position of the follower mount 240 may be located at other positions of the tilt movable plate 200.

In other embodiments, the adjustment driving structure 300 may further use a cylinder, an electric push rod, and a motor screw transmission as the driving unit. In the linear motion, corresponding sliding rails are arranged, so that the motion precision is improved, and in the rotary motion, corresponding rotary shafts are arranged, so that the rotary precision and stability can be improved.

The movable plate 200 is further provided with a plurality of position sensors, which are divided into a first position sensor 410, a second position sensor 420, a third position sensor 430, and a fourth position sensor 440 for detecting whether the ceramic wafer is positioned.

The ceramic sheet is placed on the movable flat plate 200, the movable flat plate 200 is driven to rotate by the adjusting driving structure 300, so that the ceramic sheet moves obliquely, the adjacent edges of the ceramic sheet are positioned between the included angles formed by the second positioning edge 221 and the first positioning edge 211, and whether the ceramic sheet is positioned in place or not is detected by the position sensor. Through the slope location, simple structure, the space occupies less, and the location is quick. The diameter sizes of the detection parts of the first position sensor 410, the second position sensor 420, the third position sensor 430 and the fourth position sensor 440 are less than or equal to phi 0.5mm.

The intersection point of the second positioning edge 221 and the first positioning edge 211 is p0, the center of the first position sensor 410 is p1, and the center of the second position sensor 420 is p2; the included angle theta 1 between the straight line p1p0 and the first positioning edge 211 is 0.08-0.1 degrees, and the vertical distance between the center p1 of the first position sensor 410 and the first positioning edge 211 is 0.15-0.2 mm; the included angle theta 2 between the straight line p2p0 and the second positioning edge 221 is 0.08-0.1 DEG, and the vertical distance between the center p2 of the second position sensor 420 and the second positioning edge 221 is 0.15-0.2 mm; the distance between the third position sensor 430 and the second positioning edge 221 and the first positioning edge 211 is 0.2mm to 0.3mm;

when the edge of the ceramic plate is wrinkled and exceeds the positioning edge and is lapped on the adjustable first positioning plate 210 and/or the second positioning plate 220 in the inclined positioning process, or the angle of the ceramic plate is offset by more than 0.15 degrees after the positioning is finished (the range is determined according to the included angle between the position of the sensor and the positioning edge and the size of the sensor detection part), the reflected light quantity of the position sensor 1 or 2 or 3 changes, so that the fact that the ceramic plate is not positioned well is detected and an alarm is given; the position sensor 4 is provided for detecting whether or not the movable plate 200 has a ceramic sheet.

The above is to limit the positions of the three position detection sensors, if the position is lower than the above range, the successful positioning is judged to deviate from the target position and keep the platform in an inclined state, so that erroneous judgment is caused, if the position is higher than the above range, the ceramic sheet deviation is not alarmed when the ceramic sheet deviation is larger than 0.15 degrees, a signal for lifting the platform is transmitted instead, and the positioning accuracy cannot meet the requirement.

Referring to fig. 3, the movable plate 200 is further provided with air holes 230, and the following areas are not provided with air holes 230: an isosceles triangle area with L right-angle side at the p0 point; the ceramic sheet is positioned in a region with a boundary width a of a region S0, wherein L=60 mm-70 mm and a=8 mm-15 mm. The open area s1= (50% -60%) S0. The pore diameter of the air holes 230 ranges from 0.3mm to 0.6mm, and the open pore area shole=0.001% -0.002% ×s1. The blowing pressure is 0.25-0.5 MPa, and the blowing quantity is regulated by a throttle valve. The pore diameter of the air holes 230 is too large, the ceramic plate is too large by air floatation, the pore diameter of the air holes 230 is too small, and the sliding time of the ceramic plate is prolonged. The same effect is achieved by the fact that the air blowing pressure is too high, the ceramic plate is subjected to air floatation too high, the air blowing pressure is too low, and the sliding time of the ceramic plate is prolonged.

If L is smaller than 60mm, namely the open area is too large, the ceramic plate is easily blown up to be close to the right-angle positioning part, so that the ceramic plate is separated from the platform, and if L is larger than 70mm, namely the open area is too small, the effect of air floatation of the right-angle positioning part is insufficient, and the sliding time of the ceramic plate is prolonged.

The area S1 of the open area should not be lower than 50% of the area S0 of the area occupied by the ceramic sheet after the ceramic sheet is positioned theoretically, if it is lower than 50% of the area S0, the air floating effect of the air blowing of the platform air holes 230 on the ceramic sheet is affected, and the vacuum adsorption effect is poor after the positioning is completed. The open pore area S pore also has this effect.

The inclination angle of the movable plate 200 ranges from 20 ° to 40 °, and the inclination angle can be changed by changing the eccentric wheels 340 with different eccentricities.

The invention can be used for detecting the inclined positioning of the thin sheet-shaped structure, and is not limited to the ceramic sheet.

During installation, the fixed support 100 is installed firstly, and then the movable flat plate 200 is installed, so that the movable flat plate 200 can smoothly rotate around the rotation pivot; the follower wheel 330 is mounted on the follower mounting seat 240, and then the follower mounting seat 240 is fixed at the bottom of the movable flat plate 200; assembling the eccentric wheel 340 and the eccentric wheel 340 mounting seat together and fixing the eccentric wheel 340 mounting seat; the motor and the motor mounting seat are mounted, then a synchronous belt conveying system is mounted, and the tightness of the synchronous belt is adjusted; a tension spring is installed; installing adjustable first positioning plate 210 and second positioning plate 220; installing a plurality of position sensors; and finally, is connected with a control air path of the air blowing hole 230 on the movable flat plate 200.

The invention also provides an embodiment of the using method of the ceramic wafer inclination positioning device. Comprising the following steps: the ceramic sheet product before sintering is placed on the upper part of the movable flat plate 200 through other conveying mechanisms, the motor rotates, the eccentric wheel 340 is driven to rotate through the synchronous belt transmission system, the follower wheel 330 is tightly attached to the eccentric wheel 340 under the action of the tension spring, the movable flat plate 200 is driven to rotate to a certain angle clockwise around the rotation pivot, and the ceramic sheet slides up and down on the inclined movable flat plate 200 to be in contact with the second positioning edge 221 and the first positioning edge 211. In the descending process, the air holes 230 on the movable plate 200 blow air, so that an air layer is formed between the ceramic sheet and the movable plate 200, friction is reduced, and the sliding process is smooth.

The movable plate 200 stays at the position of the maximum inclination angle for a set time, typically within 0.5 s. When the stop is finished, if the ceramic sheet is wrinkled at the edge and the edge exceeds the positioning edge and is lapped on the adjustable first positioning plate 210 and the second positioning plate 220, or the angle of the ceramic sheet is offset by more than 0.15 DEG after the positioning is finished, the reflected light quantity of the position sensor 1 or 2 or 3 is changed, and thus the ceramic sheet is detected to be well positioned and alarm is given. If no alarm condition exists, the air holes 230 on the movable flat plate 200 are switched to vacuum adsorption through the pneumatic control element, so that the ceramic wafer is prevented from moving.

Next, the motor rotates the eccentric 340, and the movable plate 200 rotates counterclockwise around the rotation pivot, and vacuum suction is maintained all the time. When the movable plate 200 rotates to the horizontal position, the motor stops rotating, and the movable plate 200 stays at the horizontal position.

Thus, the ceramic wafer is positioned.

The invention has simple structure, fewer mechanisms, low cost and stable and quick positioning effect, and realizes ideal positioning effect by monitoring by the platform sensor, and switching the positive pressure blowing and negative pressure adsorption of the air hole 230 by the inclined positioning.

While the preferred embodiments of the present invention have been illustrated and described, the present invention is not limited to the examples, and various equivalent modifications and substitutions can be made by one skilled in the art without departing from the spirit of the present invention, and these equivalent modifications and substitutions are intended to be included in the scope of the present invention as defined in the appended claims.
