Detailed Description

The following description of the embodiments of the present disclosure will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments, which can be made by one of ordinary skill in the art without inventive effort, based on the embodiments in this disclosure are intended to be within the scope of this disclosure. In addition, technical features related to different embodiments of the present disclosure described below may be combined with each other as long as they do not make a conflict with each other.

Platform detection refers to detection of one or more dimensions of a processing platform of the tooling device. Taking mechanical pressing equipment as an example, the pressing equipment comprises an upper platform and a lower platform, and the pressing technology of the product is realized by applying preset pressure on the upper platform and the lower platform. Before the lamination equipment performs lamination on the product, the flatness and deflection error of the surface of the platform of the mechanical lamination equipment are required to be detected and corrected, so that the pressure uniformity of the lamination equipment is ensured, and the machining precision of the lamination equipment is improved.

In the related art, when the deflection angle error of the platform is detected, a measuring instrument such as a level meter can be adopted for detection. However, the level detection operation is complex and the cost is high, and the level is mainly used for detecting the deflection angle of the platform in the horizontal direction, and is difficult to detect for equipment platforms with special postures. Therefore, the platform in the related art has complex detection operation, high cost and larger detection limitation.

Based on the defects in the related art, the embodiment of the disclosure provides a platform detection device, a method and a storage medium, which aim to simplify the platform detection process and improve the platform detection precision.

The embodiment of the disclosure provides a platform detection device, which can be used for detecting a processing platform of tooling equipment. For example, in some examples, the processing platform described in the present disclosure may be a processing platform of a lamination device.

As shown in fig. 1, in some embodiments, the platform detection device of the disclosed examples includes a body 310 and a detection probe. The body 310 is a main structure of the platform detection device, and has an upper surface and a lower surface on two opposite sides.

The sensing probe includes a plurality of lower probes 320 distributed at a lower surface, and a root of each lower probe 320 is connected to the body 310 by a driving means so that each lower probe 320 can be drivingly lengthened and shortened in a direction perpendicular to the lower surface. As to the specific structure of the driving device, those skilled in the art will certainly understand and fully implement the related art, and this disclosure will not be repeated.

In this disclosed embodiment, the platform detection device further includes a gyroscope, the gyroscope is disposed inside the body 310, and the gyroscope can detect pose information of the body 310 in real time. In some embodiments, the gyroscope may be of any suitable type of gyroscope for implementation, such as a three-axis gyroscope, a six-axis gyroscope, etc., as the disclosure is not limited in this regard.

The platform detection device further comprises a controller, the controller can be arranged in the body 310, and the controller can control the lower probe to stretch and retract according to the difference between the pose information detected by the gyroscope and the target pose.

It will be appreciated that the target pose represents a desired standard pose of the platform, for example in some embodiments the target pose may comprise a horizontally oriented pose, i.e. the surface of the platform is desired to be horizontal. Of course, in other embodiments, the target pose may be any other suitable platform pose, such as a tilt pose, etc., as the disclosure is not limited in this regard.

In this disclosed embodiment, when the platform detection device is freely placed on the platform to be detected, the gyroscope may acquire current pose information of the body 310, and the controller may determine a difference between the current pose of the body 310 and the target pose according to the pose information, so as to control each lower probe 320 to stretch and retract, so that the current pose of the body 310 is consistent with the target pose, and at this time, a detection result of the platform to be detected may be obtained according to stretch and retract data of each lower probe 320.

To facilitate a clear understanding of the principles of the platform detection device of the embodiments of the present disclosure, based on the detection device shown in fig. 1, the embodiments of the present disclosure provide a platform detection method that may be performed by the controller of the detection device described above.

As shown in fig. 2, in some embodiments, the platform detection method of the examples of the present disclosure includes:

s210, when the detection device is freely placed on the first platform to be detected, pose information of the detection device is obtained.

And S220, controlling each lower probe of the detection device to stretch according to the difference between the pose information and the preset target pose until the pose information is consistent with the target pose, and determining first stretch data of the lower probes.

S230, determining a detection result of the first platform to be detected according to the first telescopic data.

In the embodiment of the disclosure, the first platform to be detected is a processing platform that needs to perform detection of a deflection angle error of the platform, for example, as shown in fig. 3, and the platform 100 is the first platform to be detected. In the example embodiment of fig. 3, the target pose of the first platform to be detected 100 is in the horizontal direction, that is, it is required to determine whether a deflection angle error exists on the surface of the first platform to be detected 100 relative to the horizontal plane by using the platform detection apparatus and method according to the embodiment of the present disclosure.

When the first platform to be detected 100 is detected, the detection device can be freely placed on the surface of the first platform to be detected 100, and the pose information of the body 310 can be acquired by using the gyroscope arranged inside the body 310 of the detection device.

As shown in fig. 3 (a), in the initial state of the detection device, the telescopic lengths of the respective lower probes 320 are identical, so that when the first platform 100 to be detected has a yaw angle error, the gyroscope acquires pose information of the body 310 different from the target pose (horizontal direction).

The detecting device may control the lower probe 320 to stretch and retract according to the difference between the pose information detected by the gyroscope and the target pose, so as to adjust the pose of the body 310, so that the pose information of the body 310 detected by the gyroscope is consistent with the target pose. That is, as shown in fig. 3 (b), the body 310 is adjusted from the original inclined posture to the horizontal posture by the telescopic adjustment of the lower probe 320.

It can be appreciated that, in the case that the pose information of the body 310 is consistent with the target pose, the distribution situation of the end of the lower probe 320 may reflect the pose situation of the first platform to be detected 100. Thus, in the embodiment of the present disclosure, the detection device may determine the telescopic data of each lower probe 320 after the pose information of the body 310 is consistent with the target pose, and determine the first telescopic data according to the telescopic data of each lower probe 320.

The first telescopic data may directly reflect the pose condition of the first platform to be detected 100, so that the detection device may determine a detection result of the first platform to be detected 100 according to the first telescopic data.

Still referring to fig. 3, as shown in (b) of fig. 3, the detecting device may lock the telescopic length of each lower probe 320 after controlling the telescopic of the lower probe 320 such that the body 310 maintains the horizontal posture, and then determine the first telescopic data according to the telescopic length of each lower probe 320. The first telescopic data is pose data of the first platform to be detected 100 simulated by the lower probe 320, so that whether the first platform to be detected 100 has deflection angle errors can be determined according to the first telescopic data.

For example, in an example where the lengths of the respective lower probes 320 included in the first telescopic data are consistent or very small, it is indicated that the first platform to be detected 100 is almost consistent with the target pose, and it may be considered that there is no or only a small deflection angle error.

For example, in another example, the lengths of the lower probes 320 included in the first telescopic data are inconsistent, for example, in fig. 3, the lengths of the lower probes 320 gradually become larger in the direction from the left side to the right side of the drawing, which indicates that a deflection angle error exists between the first platform to be detected 100 and the target pose, and a specific deflection angle can be determined by using a preset algorithm according to the first telescopic data and the target pose.

According to the embodiment of the disclosure, the lower probe of the detection device is utilized to simulate the pose of the first platform to be detected, so that the error detection of the deflection angle of the platform can be automatically realized, the operation is simple, the detection device is simple in structure, the detection precision is high, and the detection effect of the platform is improved.

In some platform detection scenarios, it is often necessary to perform error detection in multiple dimensions on the platform. Taking mechanical pressing equipment as an example, when detecting a platform of the pressing equipment, besides detecting a deflection angle error of the platform, the surface flatness of the platform is often required to be detected. If the surface of the platform is uneven, uneven stress on each part of the product in the pressing process can be caused, so that the pressing effect is poor.

In the related art, when the flatness of the surface of the platform is detected, the flatness is often realized by adopting pressure-sensitive paper, and the color shade changes generated under the condition that the pressure-sensitive paper is subjected to different pressures are different, so that whether the surface of the platform has uneven flatness errors can be determined by observing the color distribution of the pressure-sensitive paper.

It can be seen that in the related art, the flatness detection and deflection error detection of the surface of the platform need to be separately tested, and the steps are complicated. Moreover, the flatness is not objective enough to be detected by utilizing the color change of the pressure-sensitive paper, and the flatness is greatly influenced by subjective experience of operators, so that the detection error is larger.

In the embodiment of the present disclosure, detection of the deflection angle error of the stage and the flatness of the surface of the stage can be simultaneously achieved by using the stage detection device, and the following embodiments will be specifically described.

In some embodiments, the detection apparatus of examples of the present disclosure further comprises a pressure sensor. For example, as shown in the embodiment of fig. 1, a pressure sensor may be provided inside the body 310, and a sensing terminal is connected to each sensing probe, so that pressure information, such as a pressure value, a pressure direction, etc., of each lower probe 320 may be sensed. In one example, the pressure sensor may be a diaphragm pressure sensor, or any other sensor suitable for achieving pressure detection, as the disclosure is not limited in this regard.

Referring to fig. 3, when the detecting device is placed on the first platform to be detected 100, if the lower probe 320 is in contact with the first platform to be detected 100, the pressure sensor can detect that the lower probe 320 has a certain pressure value. Conversely, if the lower probe 320 is not in contact with the first platform 100 to be detected, the pressure sensor will not detect the pressure value of the lower probe 320.

Therefore, in one example scenario, when the detection device is freely placed on the first platform to be detected 100, if a concave area exists at a certain position on the surface of the first platform to be detected 100, the end of the lower probe 320 at the concave area will not directly contact with the surface of the platform, so that the pressure sensor detects that the pressure information of the lower probe 320 is zero. Based on the principle, the surface flatness of the first platform to be detected 100 can be detected. The platform detection method of the present disclosure is described below with reference to the embodiment of fig. 4.

As shown in fig. 4, in some embodiments, the platform detection method of the examples of the present disclosure includes:

s410, when the detection device is freely placed on the first platform to be detected, first pressure information of each lower probe is acquired.

And S420, controlling the expansion and contraction of each lower probe to be in abutting contact with the surface of the first platform to be detected according to the first pressure information and the difference between the pose information and the target pose until the pose information is consistent with the target pose, and determining the expansion and contraction data of the lower probes.

As shown in fig. 5, in some example scenarios, the first platform 100 to be detected has not only deflection angle errors with respect to the horizontal plane, but also surface irregularities errors. In the embodiment of the disclosure, the detection device and the detection method can be utilized to simultaneously detect the deflection angle and the unevenness.

In some embodiments, when the detection device is freely placed on the first detection platform 100, based on the foregoing, the current pose information may be acquired through a gyroscope inside the body 310. Meanwhile, the pressure information of each lower probe 320, that is, the first pressure information described in the present disclosure, may also be acquired through a pressure sensor inside the body 310.

For example, in the case where the detecting means is freely placed as shown in fig. 5 (a), since the depression area exists on the surface of the stage, the end of the lower probe located at the depression area does not come into abutting contact with the surface of the stage, so that the pressure information of the lower probe 320 at the position detected by the pressure sensor is zero.

When the body 310 is adjusted in position by the retraction of the lower probe 320, the detection device controls the extension of the lower probe 320 with zero pressure information until the end of the lower probe 320 contacts the surface of the platform. For example, as shown in fig. 5 (b), while maintaining the posture of the body 310 in conformity with the target posture, it is also necessary to bring each of the lower probes 320 into abutting contact with the surface of the first platform to be detected 100.

In the embodiment of the present disclosure, after the body 310 is adjusted to the target pose and each lower probe 320 is in abutting contact with the surface of the platform, the telescoping of each lower probe 320 is locked, and the first telescoping data is determined according to the telescoping data of the lower probe 320 at this time.

It can be appreciated that, in the embodiment of the present disclosure, the first telescopic data includes not only a representation of the deflection angle pose of the first platform to be detected 100, but also a representation of the surface flatness of the first platform to be detected 100, so after the first telescopic data is determined, the detection result for the first platform to be detected 100 can be determined according to the first telescopic data. That is, the detection result includes both the deflection angle error result and the flatness error result of the first platform to be detected 100.

According to the embodiment of the disclosure, the detection device can be used for simultaneously detecting the deflection angle and the surface flatness of the platform, so that the detection flow of the platform is simplified, the surface flatness detection result can be obtained more accurately compared with pressure sensitive paper, and the detection precision and the detection effect of the platform are improved.

For mechanical pressing equipment, not only the lower platform of the pressing equipment is required to be detected, but also the upper platform of the pressing equipment is required to be detected. For example, as shown in fig. 6, the laminating apparatus generally includes a lower stage 10 and an upper stage 20, and the upper stage 20 and the lower stage 10 are drivingly movable relative to each other. The product 30 to be pressed can be placed on the surface of the lower platform 10, and the upper platform 20 is pressed down under a preset pressure in a driving manner, so that the product 30 to be pressed is pressed.

In some embodiments of the present disclosure, the detection device may not only detect the lower platform 10 of the pressing device, but also detect the upper platform 20 of the pressing device at the same time. The following describes the embodiment of fig. 7.

As shown in fig. 7, in some embodiments, the platform detection device of the disclosed examples, the detection probes include not only the aforementioned lower probes 320, but also the upper probes 330. The upper probes 330 are distributed on the upper surface of the body 310, and the root of each upper probe 330 is connected to the body 310 by a driving means, so that each upper probe 330 can be drivingly lengthened and shortened in a direction perpendicular to the upper surface.

In the embodiment of the present disclosure, the sensing end of the pressure sensor is also connected to each upper probe 330, so that pressure information of each upper probe 330 can be collected and detected, and the controller can control the upper probes 330 to be extended and retracted according to the pressure information.

When detecting the upper platform of the pressing device, the detecting device may be disposed between the upper platform and the lower platform, the detection of the lower platform is the same as that of the foregoing embodiment of fig. 2 to 5, after determining the detection result of the lower platform, the detecting device may be pressed down by the upper platform with a preset pressure, the upper probe is controlled to stretch according to the pressure information of the upper probe 330, so as to obtain the second pressure information and the second stretch data of the upper probe, and the detection result for the upper platform is determined according to the second pressure information and the second stretch data. The following is a detailed description of the embodiment of fig. 8.

As shown in fig. 8, in some embodiments, the platform detection method of the examples of the disclosure further includes, after obtaining the detection result of the first platform to be detected:

s810, acquiring second pressure information of an upper probe of the detection device when the second platform to be detected is pressed on the detection device by preset pressure.

As shown in fig. 9, in the embodiment of the disclosure, the first platform to be detected 100 is a lower platform of the lamination device, and the second platform to be detected 200 is an upper platform of the lamination device. The process of determining the detection result of the first platform to be detected 100 is only required by a person skilled in the art, and the disclosure will not be repeated herein.

After the detection result of the first platform to be detected 100 is obtained, the second platform to be detected 200 may be controlled to press the detection device with a preset pressure, where the preset pressure may be the pressure when the pressing device presses the product to be pressed, and a person skilled in the art may set the pressure according to a specific application scenario, which is not limited in this disclosure.

It will be appreciated that, when the second platform to be tested 200 is pressed against the testing device, the pressure sensor of the testing device may obtain the pressure information of the position of each upper probe 330, that is, the second pressure information, where the second pressure information indicates the pressure distribution information received by the testing device. For example, the second pressure information in the embodiment of fig. 9 may be as shown in fig. 10, where each circle in fig. 10 represents one upper probe 330, and the numerical values in the circles represent the magnitude of the pressure value at the location of the upper probe 330.

For example, as shown in fig. 9 (a), the second platform 200 to be detected has an inclination deviation, and the contact degree between the upper probe 330 and the second platform 200 to be detected is smaller from the left side to the right side of the drawing, so that when the second platform 200 to be detected presses the detecting device with a preset pressure, the pressure on the left side of the drawing is larger than the pressure on the right side. It can also be seen from the illustration of fig. 10 that the pressure distribution gradually decreases from the left side to the right side. That is, in the embodiment of the present disclosure, the deflection angle error information of the upper stage may be reflected by the second pressure information.

S820, controlling the upper probe to stretch and contract to be in contact with the surface of the second platform to be detected according to the second pressure information, and determining second stretch and contract data of the upper probe.

As shown in fig. 9 (a), in this example, since the second stage to be inspected 200 has a deflection angle error and a surface flatness error, when the second stage to be inspected 200 presses the inspection device, on the one hand, the respective upper probes 330 are unevenly stressed, and on the other hand, since a part of the upper probes 330 are not in direct contact with the second stage to be inspected 200, the pressure information at this position is zero. In the embodiment of the disclosure, the upper probe 330 with zero pressure information can be controlled to stretch and retract, so that the end of the upper probe contacts with the surface of the second platform 200 to be detected, and the second stretching data of the upper probe is obtained. The following is a description with reference to fig. 11.

As shown in fig. 11, in some embodiments, the platform detection method of the examples of the present disclosure, the process of determining the second scalable data includes:

and S821, determining each upper probe with the pressure of zero in the second pressure information.

S822, controlling the upper probes with zero pressure to stretch and contract so as to enable the upper probes to be in abutting contact with the surface of the second platform to be detected, and determining second stretch data of the upper probes.

As shown in fig. 9 and 10, the area where the pressure is zero exists in the second pressure information, and as can be seen from the foregoing, the position where the pressure is zero indicates that the upper probe 330 is not in direct contact with the surface of the second platform to be detected 200.

For example, as shown in fig. 10, the pressure values of the two probe positions at the upper right corner are zero, and the second pressure information distribution conforms to the sequential decrease of the upper pressure values from left to right and from bottom, indicating that the probe positions are due to the absence of contact between the upper probe 330 and the platform surface due to the deflection angle error of the second platform 200 to be detected. For the probe position of row 4 and column 2 in the second pressure information distribution shown in fig. 10, the pressure value at this position is zero, but it does not obviously conform to the pressure change rule, so that the upper probe 330 at this position is not in contact with the platform surface due to the presence of the recessed area of the second platform 200 to be detected.

It can be seen from this example that the second pressure information distribution can simultaneously represent the deflection angle error and the surface flatness of the second platform to be detected.

In this embodiment of the disclosure, the upper probes 330 with the pressure value of zero may be controlled to stretch and contract to make contact with the surface of the second platform 200 to be detected, and then stretch and contract of each upper probe 330 is locked to obtain stretch and contract data of each upper probe 330, that is, the second stretch and contract data in this disclosure.

S830, determining a detection result of the second platform to be detected according to the second pressure information and the second expansion data.

Based on the foregoing, the second pressure information may reflect the deflection angle error and the surface flatness of the second platform to be detected 200, and the second stretching data may also simulate the surface shape of the second platform to be detected 200 by using the stretching of the upper probe 330. Therefore, in the embodiment of the present disclosure, the detection result of the second platform to be detected may be determined by combining the second pressure information and the second expansion data, that is, the detection result of the deflection angle of the second platform to be detected 200 and the detection result of the surface flatness are included at the same time.

Moreover, the stress condition of each part of the pressing equipment can be accurately quantified by using the pressure sensor, the influence of human factors is avoided, and the detection precision is improved.

In some embodiments, as can be seen from the foregoing fig. 5, the upper surface of some products 30 to be pressed is not a plane, for example, a screen module of a partially curved screen mobile phone, and a curved surface area is present at the edge of the screen module, so that the pressing effect of the curved surface area should be ensured, and the uniformity of the stress of the curved surface area and the plane area should be ensured. Therefore, in the embodiment of the present disclosure, the upper surface of the product to be pressed may be simulated by using the upper probe 330 of the detecting device, so that the pressure uniformity detection may be performed on the pressing apparatus more accurately.

As shown in fig. 12, in some embodiments, the platform detection method of the present disclosure further includes, before the pressing the detection device with the second platform to be detected:

s1210, obtaining the shape data of the product to be pressed.

S1220, controlling the upper probe to stretch according to the shape data so that the end distribution of the upper probe is consistent with the shape of the product to be pressed.

Specifically, before the product to be pressed is produced, the shape data of the product to be pressed and the pressing data in the pressing process are predetermined, where the shape data may include, for example, the shape size of the product to be pressed, and the pressing data may include, for example, the preset pressure of the product to be pressed.

In the embodiment of the disclosure, the profile data of the product to be pressed may be obtained, and the upper probe 330 may be controlled to stretch according to the profile data, so that the end distribution of the upper probe 330 is consistent or approximately consistent with the shape of the upper surface of the product to be pressed.

In one example, as shown in fig. 13 (a), a dotted line portion represents the outer shape of the product to be bonded 30, and in this example, the upper surface of the product to be bonded 30 is a plane, so that the telescoping lengths of the respective upper probes 330 are controlled to be uniform, so that the end portions of the plurality of upper probes 330 are distributed to form a plane structure.

In another example, as shown in (b) of fig. 13, a dotted line portion represents the outer shape of the product 30 to be pressed, and in this example, the upper surface of the product to be pressed is curved, so that the respective upper probes 330 are controlled to be contracted and contracted, so that the end portions of the plurality of upper probes 330 are distributed to form a curved surface structure in conformity with the upper surface of the product to be pressed.

Of course, it will be appreciated that the shape of the product to be laminated is not limited to the above examples, but may be any other shape structure suitable for implementation, and the disclosure is not limited thereto.

As can be seen from the foregoing, in the embodiment of the present disclosure, the detection device may be used to implement the simulation press fit detection for any product shape, so as to improve the universality of the detection method, simplify the detection flow, and improve the detection accuracy.

In some embodiments, considering that the requirements of different product productions on precision are different, after the detection result is determined by using the platform detection method disclosed by the disclosure, whether to correct and adjust the platform can be determined according to the error size of the detection result.

Specifically, in some embodiments, the platform detection method of the examples of the present disclosure further includes:

and responding to the detection result of the first platform to be detected and/or the second platform to be detected to meet the preset condition, and adjusting the first platform to be detected and/or the second platform to be detected based on the detection result.

In some embodiments, a preset threshold may be set for the flatness and/or deflection angle of the platform surface. It can be understood that the preset threshold value indicates that the platform error exceeds a critical value of a required standard, and after the detection result of the platform is determined, when the deflection angle error and/or the surface flatness error of the detection result are not smaller than the preset threshold value, it is indicated that the error existing in the platform cannot meet the production requirement, so that the platform can be corrected and adjusted according to the deflection angle error and/or the surface flatness error of the detection result. On the contrary, when the deflection angle error and the surface flatness error of the detection result are smaller than the preset threshold value, the error of the platform is small, so that the production requirement can be met, and the platform does not need to be corrected and adjusted.

According to the embodiment of the disclosure, the lower probe of the detection device is utilized to simulate the pose of the first platform to be detected, so that the error detection of the deflection angle of the platform can be automatically realized, the operation is simple, the detection device is simple in structure, the detection precision is high, and the detection effect of the platform is improved. The detection device can be used for simultaneously detecting the deflection angle and the surface flatness of the platform, the detection flow of the platform is simplified, the surface flatness detection result can be obtained more accurately compared with pressure sensitive paper, and the detection precision and the detection effect of the platform are improved. The deflection angle error detection and the surface flatness detection of the two platforms of the pressing equipment can be realized simultaneously by using the detection device, separate detection is not needed, and the detection flow of the pressing equipment is simplified. Moreover, the stress condition of each part of the pressing equipment can be accurately quantified by using the pressure sensor, the influence of human factors is avoided, and the detection precision is improved.
