Description

Technical Field

[0001] The embodiments of the present disclosure relate to the field of scraper detection, and in particular to a scraper flatness detection device and a scraper flatness detection method. Background Art

[0002] Today's circuit boards are printed with solder paste scrapers. As the scraper is used for a longer time, it is easy for the scraper to be damaged, resulting in uneven scraper surface. It is necessary to promptly test the scraper flatness so that the scraper can be replaced in time. At present, when testing the scraper flatness, the usual method is: the scraper flatness testing device presses the scraper on a plane and tests the scraper flatness by manual observation, or uses a scraper flatness testing device including a laser scanner to scan the entire scraper and check the overall flatness of the scraper through mathematical modeling.

[0003] However, when the above method is used to detect scraper flatness, the following technical problems often occur:

[0004] First, when the scraper is pressed on a flat surface for observation, the pressure is not controlled. When the pressure is greater than the maximum pressure that the scraper can withstand, the scraper will be damaged, thereby increasing the loss of the scraper;

[0005] Second, when using a laser scanner to detect the flatness of the scraper, the laser scanner is prone to noise, and the scraper needs to be scanned multiple times to improve the precision and accuracy of the scraper flatness detection, which makes it difficult to detect the scraper flatness in a timely manner. When the laser transmitter is damaged, it is difficult to replace and repair it in time, which makes it difficult to detect the scraper flatness in a timely manner;

[0006] Third, in the scraper flatness detection, the manual observation method will lead to a decrease in the detection accuracy, while the mathematical modeling method increases the complexity of the calculation, resulting in a waste of computing resources (for example, central processing unit);

[0007] In the process of adopting technical solutions to solve the above-mentioned technical problem three, the following technical problem four is often accompanied: when a photosensitive sensor is used to receive a light signal, when the intensity of the light signal decreases, the accuracy of the photosensitive sensor will decrease, thereby reducing the accuracy of the scraper flatness detection. In response to the above-mentioned technical problem three, the conventional solution is generally to use a phase-locked amplifier to amplify the signal converted by the photosensitive sensor. However, the above-mentioned conventional solution still has the following problem: the phase-locked amplifier is a large device that is difficult to move at any time, which will reduce the adaptability of the scraper flatness detection.

The scraper fixture 108 is used to fix the scraper. Specifically, the light strip 109 can be installed between the balance bar 10431 and the wooden shell 102.

[0041] As an example, the light strip 109 may be a LED (Light-Emitting Diode) light strip.

[0042] Therefore, whether the scraper is flat can be determined by determining whether the light emitted by the light strip 109 passes through the scraper fixed on the balance bar 10431. The light strip 109 is installed in the wooden housing 102, which can improve the focusing effect and increase the intensity of the light signal emitted by the light strip 109, so as to increase the accuracy of the scraper flatness detection.

Wherein: the main control chip 1101 included in the scraper transport device 110 is communicated with the scraper transport assembly 1102. Wherein, the scraper transport device 110 is used to transport the scraper. The main control chip 1101 included in the scraper transport device 110 is communicated with the alarm device 1104. Wherein, the alarm device 1104 can be used to perform an alarm operation. The main control chip 1101 included in the scraper transport device 110 is communicated with the push pressure gauge 1042. The main control chip 1101 included in the scraper transport device 110 is communicated with the photosensor assembly 1103. The feeler gauge assembly 111 is fixedly connected to the scraper conveying assembly 1102 included in the scraper conveying device 110. The feeler gauge assembly 111 can be used to measure the distance between the scraper and the marble workbench 101.

[0044] The main control chip 1101 may be a chip for controlling the scraper conveying device. The alarm device 1104 may include but is not limited to at least one of the following: a display screen and a speaker. The alarm operation may be that the display screen included in the alarm device 1104 displays warning words or the speaker included in the alarm device 1104 emits a warning sound.

[0045] As an example, the main control chip 1101 may be, but is not limited to, at least one of the following: a single chip microcomputer, a microcontroller or a FPGA (Field Programmable Gate Array). The scraper transport component 1102 may be a robotic arm.

[0046] The above-mentioned design of the scraper conveying device is an inventive point of the embodiment of the present disclosure, which solves the second technical problem raised by the background technology, "it is difficult to detect the flatness of the scraper in time". The factors that make it difficult to detect the flatness of the scraper in time are often as follows: when using a laser scanner to detect the flatness of the scraper, the laser scanner is prone to noise, and it is necessary to scan the scraper multiple times to improve the precision and accuracy of the scraper flatness detection, which makes it difficult to detect the flatness of the scraper in time, and when the laser transmitter is damaged, it is difficult to replace and repair it in time. If the above factors are solved, the flatness of the scraper can be detected in time. In order to achieve this effect, the present disclosure can continuously receive the light signal emitted by the light strip through a photosensitive sensor. Then, the main control chip can determine whether there is light passing through the gap between the scraper and the marble workbench according to the intensity of the received light signal, that is, determine whether the scraper is flat. As a result, while ensuring the detection accuracy, there is no need to use a laser scanner, only a light strip and a photosensitive sensor are needed to detect the flatness of the scraper. Furthermore, since the light strip and the photosensitive sensor are simple and easy-to-obtain equipment, when the light strip and the photosensitive sensor are damaged, they can be replaced and repaired in time. Thus, the scraper flatness detection can be carried out in time.

[0047] In practice, the scraper flatness detection device can be configured to perform the following steps:

[0048] In the first step, the main control chip controls the scraper transport assembly to fix the scraper on the scraper clamp. First, the main control chip can send a movement control signal to the scraper transport assembly. Here, the movement control signal can be a signal indicating "clamping the scraper". Then, in response to receiving the movement control signal, the scraper transport assembly can control the scraper clamp to clamp the scraper.

[0049] In the second step, the main control chip controls the scraper transport assembly to install the scraper clamp on the balance bar. The main control chip can send a fixed control signal to the scraper transport assembly. Here, the fixed control signal can be a signal representing "fixed scraper". Then, in response to receiving the fixed control signal, the scraper transport assembly can control the scraper clamp to pass through the limit hole set on the balance bar and install the scraper clamp on the balance bar.

[0050] In the third step, the main control chip controls the scraper transport assembly to move the crank handle, to control the push pressure gauge and the balance bar to press the scraper down to the marble workbench, and to obtain the scraper pushing force value from the push pressure gauge. The main control chip can send a pushing control signal to the scraper transport assembly. Here, the pushing control signal can be a signal representing "pushing the scraper". Then, in response to receiving the movement control signal, the scraper transport assembly can control the crank handle to rotate, to control the push pressure gauge and the balance bar to press the scraper down to the marble workbench. Finally, the main control chip can obtain the scraper pushing force value from the push pressure gauge through a wired connection or a wireless connection. Here, the scraper pushing force value can represent the pressure applied to the scraper by the cylinder structural component assembly measured by the push pressure gauge.

[0051] In the fourth step, the main control chip stops controlling the scraper transport component in response to determining that the scraper pushing force value is within the target range. First, the main control chip can send a stop movement signal to the scraper transport component. Here, the stop movement signal can be a signal indicating "stop turning the shaking handle". Then, in response to receiving the stop movement signal, the scraper transport component stops turning the shaking handle.

[0052] As an example, the target interval may be (2.5, 3.5).

[0053] In the fifth step, the light sensor assembly receives the light signal from the light strip, and sends the scraper light transmission signal to the main control chip. The light sensor assembly can receive the light signal emitted by the light strip through the scraper in real time. Here, the light signal can be an analog signal. Then, the light signal can be converted into a scraper light transmission signal. Here, the scraper light transmission signal can be an electrical signal. Finally, the scraper light transmission signal can be sent to the main control chip.

[0054] In the sixth step, the main control chip generates a scraper light illumination value based on the scraper light transmission signal.

[0055] In the seventh step, the main control chip sends a photosensitive abnormality alarm signal to the alarm device in response to determining that the scraper light illumination value is greater than the target threshold. The photosensitive abnormality alarm signal may be a signal indicating that "the light signal is sensed and the scraper is not smooth".

[0056] As an example, the target threshold mentioned above may be 0.1.

[0057] In step 8, the alarm device performs an alarm operation in response to receiving the abnormal light-sensitive alarm signal, wherein the alarm operation may be displaying warning text or emitting a warning sound.

[0058] As an inventive point of an embodiment of the present disclosure, the above-mentioned scraper flatness detection method solves the technical problem three "waste of computing resources (for example, central processing unit)" raised by the background technology. The factors that lead to the waste of computing resources (for example, central processing unit) are often as follows: In the scraper flatness detection, the manual observation method will lead to a decrease in the accuracy of the detection, while the mathematical modeling method increases the complexity of the calculation. If the above-mentioned factors are solved, the waste of computing resources can be reduced. In order to achieve this effect, the scraper flatness detection device included in the present disclosure can firstly control the scraper transport component to fix the scraper on the scraper clamp. Secondly, the above-mentioned main control chip controls the above-mentioned scraper transport component to install the above-mentioned scraper clamp on the balance bar. In this way, the scraper can be fixed on the scraper detection device included in the scraper flatness detection device. Then, the above-mentioned main control chip controls the above-mentioned scraper transport component to move the crank to control the push pressure gauge and the balance bar to press the above-mentioned scraper down to the marble workbench, and obtain the scraper push pressure value from the above-mentioned push pressure gauge. Thus, the scraper can be controlled to be pressed down, and the pressure value of the scraper can be obtained in time by pushing the pressure gauge. Then, the main control chip stops controlling the scraper transport assembly in response to determining that the scraper push pressure value is within the target range. Thus, the accuracy of the pressure controlling the scraper to be pressed down can be improved to avoid the scraper being damaged due to excessive force. Subsequently, the photosensitive sensor assembly receives a light signal from the light strip, and sends the scraper light transmission signal to the main control chip. Then, the main control chip generates a scraper light illumination value based on the scraper light transmission signal. Thus, it can be determined whether the scraper is flat or damaged based on the size of the light signal passing through the scraper. Then, the main control chip sends a photosensitive abnormal alarm signal to the alarm device in response to determining that the scraper light illumination value is greater than the target threshold. Finally, the alarm device performs an alarm operation in response to receiving the photosensitive abnormal alarm signal. Thus, after determining that the scraper is damaged, an alarm can be issued in time to replace the scraper. Therefore, the scraper flatness detection device can control the scraper to press down to the marble workbench by obtaining the pressure value of the push pressure gauge. Then, the scraper can be illuminated by the light strip. When the scraper is damaged, the intensity change of the light signal can be sensed by the photosensitive sensor. The scraper flatness detection device can confirm that the scraper is damaged and issue an alarm in time. Therefore, there is no need to mathematically model the scraper as a whole, which reduces the complexity of the calculation and thus reduces the waste of computing resources.

[0059] The above-mentioned embodiments of the present disclosure have the following beneficial effects: the scraper flatness detection device of some embodiments of the present disclosure includes: a marble workbench, a wooden shell, a fixed bracket and a scraper detection device, wherein: the scraper detection device includes: a shaking hand, a push pressure gauge, and a scraper fixing assembly, wherein the shaking hand included in the scraper detection device is fixedly connected to the push pressure gauge, the scraper fixing assembly included in the scraper detection device is fixedly connected to the push pressure gauge, the shaking hand is used to control the movement of the push pressure gauge, and the scraper fixing assembly is used to fix the scraper; the wooden shell is installed on the marble workbench; the fixed bracket is fixed in the wooden shell; the scraper detection device is installed on the fixed bracket. Therefore, the scraper flatness detection device can fix the scraper through the scraper fixing assembly, and then the scraper can be pressed down to the smooth marble workbench by the shaking hand. Then, the pressure value of the scraper can be determined according to the reading of the push pressure gauge. When the pressure value reaches the target pressure value (for example, 5 kg), stop pressing the scraper down. This can reduce the possibility of the scraper being damaged due to pressure, thereby reducing the wear and tear of the scraper.

[0060] Next reference Figure 6 The present disclosure also provides a scraper flatness detection method for the scraper flatness detection device of each of the above embodiments, such as Figure 6 As shown, it shows a flowchart 600 of some embodiments of the scraper flatness detection method disclosed in the present invention. The scraper flatness detection method may include the following steps:

[0061] Step 601, the main control chip controls the scraper transport assembly to fix the scraper on the scraper fixture.

[0062] In some embodiments, the main control chip of the scraper flatness detection device can control the scraper transport component to fix the scraper on the scraper clamp. First, the main control chip can send a movement control signal to the scraper transport component. Here, the movement control signal can be a signal representing "clamping the scraper". Then, in response to receiving the movement control signal, the scraper transport component can control the scraper clamp to clamp the scraper.

[0063] Step 602: the main control chip controls the scraper transport assembly to install the scraper fixture on the balance bar.

[0064] In some embodiments, the main control chip can control the scraper transport assembly to install the scraper clamp on the balance bar. The main control chip can send a fixed control signal to the scraper transport assembly. Here, the fixed control signal can be a signal representing "fixed scraper". Then, in response to receiving the fixed control signal, the scraper transport assembly can control the scraper clamp to pass through the limit hole set on the balance bar and install the scraper clamp on the balance bar.

[0065] Step 603, the main control chip controls the scraper transport assembly to move the crank, controls the push pressure gauge and the balance bar to press the scraper down to the marble workbench, and obtains the scraper push pressure value from the push pressure gauge.

[0066] In some embodiments, the main control chip can control the scraper transport assembly to move the crank to control the push pressure gauge and the balance bar to press the scraper down to the marble workbench, and obtain the scraper pushing force value from the push pressure gauge. The main control chip can send a pushing control signal to the scraper transport assembly. Here, the pushing control signal can be a signal representing "pushing the scraper". Then, in response to receiving the movement control signal, the scraper transport assembly can control the crank to rotate to control the push pressure gauge and the balance bar to press the scraper down to the marble workbench. Finally, the main control chip can obtain the scraper pushing force value from the push pressure gauge through a wired connection or a wireless connection. Here, the scraper pushing force value can represent the pressure applied to the scraper by the cylinder structural component assembly measured by the push pressure gauge.

[0067] It should be noted that the above-mentioned wireless connection methods may include but are not limited to 3G / 4G connection, WiFi connection, Bluetooth connection, WiMAX connection, Zigbee connection, UWB (ultra wideband) connection, and other wireless connection methods currently known or to be developed in the future.

[0068] Step 604 : In response to determining that the scraper pushing force value is within a target range, the main control chip stops controlling the scraper transport assembly.

[0069] In some embodiments, the main control chip may stop controlling the scraper transport assembly in response to determining that the scraper pushing force value is within the target range. First, the main control chip may send a stop movement signal to the scraper transport assembly. Here, the stop movement signal may be a signal indicating "stop turning the shaking handle". Then, in response to receiving the stop movement signal, the scraper transport assembly stops turning the shaking handle.

[0070] As an example, the target interval may be (2.5, 3.5).

[0071] Step 605: the light sensor assembly receives the light signal from the light strip, and sends the scraper light transmission signal to the main control chip.

[0072] In some embodiments, the light sensor assembly can receive a light signal from the light strip, and send a scraper light transmission signal to the main control chip. The light sensor assembly can receive the light signal emitted by the light strip through the scraper in real time. Here, the light signal can be an analog signal. Then, the light signal can be converted into a scraper light transmission signal. Here, the scraper light transmission signal can be an electrical signal. Finally, the scraper light transmission signal can be sent to the main control chip.

[0073] Step 606: The main control chip generates a scraper light illumination value based on the scraper light transmission signal.

[0074] In some embodiments, the main control chip may generate a scraper light illumination value based on the scraper light transmission signal.

[0075] Considering the problems of the above conventional solutions, facing the above technical problem 4: when using a photosensitive sensor to receive a light signal, when the intensity of the light signal decreases, the accuracy of the photosensitive sensor will decrease, thereby reducing the accuracy of the scraper flatness detection. Combined with the current status of the photoelectric signal detection technology, it can be decided to adopt the following solution.

[0076] In some optional implementations of some embodiments, the main control chip generates a scraper light illumination value based on the scraper light transmission signal, which may include the following steps:

[0077] The first step is to perform a first amplification process on the filter scraper light transmission signal to obtain an amplified light transmission signal. The filter scraper light transmission signal can be amplified by a preset amplifier to obtain an amplified light transmission signal.

[0078] As an example, the aforementioned preset amplifier may be an operational amplifier.

[0079] The second step is to modulate the amplified light-transmitting signal to obtain a modulated light-transmitting signal. The amplified light-transmitting signal can be modulated by a preset modulation method to obtain a modulated light-transmitting signal.

[0080] As an example, the above-mentioned preset modulation method may be but is not limited to at least one of the following: an amplitude keying method, a frequency shift keying method, a phase shift keying method or an orthogonal amplitude method.

[0081] The third step is to sample the modulated light transmission signal to obtain a sampled light transmission signal, a first reference light transmission signal, and a second reference light transmission signal. The modulated light transmission signal can be sampled by a sampler to obtain a sampled light transmission signal, a first reference light transmission signal, and a second reference light transmission signal. The first reference light transmission signal and the second reference light transmission signal can be orthogonal to each other.

[0082] As an example, the sampler may be an ADC (Analog-to-Digital Converter).

[0083] In the fourth step, based on the first reference light transmission signal and the second reference light transmission signal, the sampled light transmission signal is subjected to a second amplification process to obtain a target light transmission signal.

[0084] The fifth step is to determine the modulus of the target light transmission signal as the scraper light illumination value.

[0085] In some optional implementations of some embodiments, performing a second amplification process on the sampled light transmission signal based on the first reference light transmission signal and the second reference light transmission signal to obtain a target light transmission signal may include the following steps:

[0086] In the first step, the product of the sampled light-transmitting signal and the first reference light-transmitting signal is determined as a first superposition signal.

[0087] The second step is to filter the first superimposed signal to obtain a first filtered signal. The first superimposed signal can be filtered using a preset filtering algorithm to obtain the first filtered signal.

[0088] As an example, the above-mentioned preset filtering algorithm may be but is not limited to at least one of the following: a FIR (Finite Impulse Response, finite unit impulse response) low-pass filter or an IIR (Infinite Impulse Response, infinite impulse response) low-pass filter.

[0089] In the third step, the product of the sampled light-transmitting signal and the second reference light-transmitting signal is determined as the second superposition signal.

[0090] The fourth step is to filter the second superimposed signal to obtain a second filtered signal. The second superimposed signal can be filtered using the preset filtering algorithm to obtain the second filtered signal.

[0091] In the fifth step, the sum of the first filtered signal and the second filtered signal is determined as the target light transmission signal.

[0092] The above-mentioned design of the scraper conveying device is an inventive point of an embodiment of the present disclosure, which solves the technical problem 4 "the accuracy of scraper flatness detection is reduced" raised by the background technology. The factors that lead to the cost increase due to the reduced accuracy of scraper flatness detection are often as follows: when a photosensitive sensor is used to receive a light signal, when the intensity of the light signal is reduced, the accuracy of the photosensitive sensor will be reduced. If the above factors are solved, the accuracy of scraper flatness detection can be improved. In order to achieve this effect, the present disclosure can firstly perform a first amplification process on the signal converted by the photosensitive sensor through an operational amplifier. Then, the amplified signal can be modulated and sampled in turn to select the target signal from the amplified signal for a second amplification process to improve the accuracy of the photosensitive sensor. Finally, the signal after the second amplification can be processed by modulus value to characterize the characteristics of the light signal received by the photosensitive sensor. Therefore, the target signal can be amplified and feature extracted by using a more portable amplifier circuit and programming algorithm, thereby improving the accuracy of the signal converted by the photosensitive sensor, and further, the accuracy of scraper flatness detection can be improved.

[0093] Step 607 : In response to determining that the scraper light illumination value is greater than the target threshold, the main control chip sends a photosensitivity abnormality alarm signal to the alarm device.

[0094] In some embodiments, the main control chip may send a photosensitive abnormality alarm signal to the alarm device in response to determining that the scraper light illumination value is greater than the target threshold. The photosensitive abnormality alarm signal may be a signal indicating that "the light signal is sensed and the scraper is uneven".

[0095] As an example, the target threshold mentioned above may be 0.1.

[0096] Step 608: The alarm device performs an alarm operation in response to receiving the photosensitivity abnormality alarm signal.

[0097] In some embodiments, the alarm device may perform an alarm operation in response to receiving the abnormal light-sensitive alarm signal, wherein the alarm operation may be displaying warning text or emitting a warning sound.

[0098] Optionally, the scraper flatness detection method may further include the following steps:

[0099] In the first step, the main control chip sends a measurement prompt signal to the scraper transport assembly in response to determining that the scraper light illumination value is less than or equal to the target threshold value. The measurement prompt signal may be a signal indicating "using a feeler gauge for measurement".

[0100] In the second step, the scraper transport assembly controls the feeler gauge assembly to measure the scraper spacing value between the scraper and the marble workbench, and obtains the scraper spacing value from the feeler gauge assembly. The scraper transport assembly can insert each feeler gauge in the feeler gauge assembly between the scraper and the marble workbench in order from small to large feeler gauge specifications, and then determine the feeler gauge specification corresponding to the first feeler gauge that can pass through the gap between the scraper and the marble as the scraper spacing value.

[0101] As an example, the feeler gauge specification of the feeler gauge in the above-mentioned feeler gauge assembly can be but is not limited to at least one of the following: 0.03 mm, 0.04 mm, 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm or 0.10 mm.

[0102] In the third step, the scraper transport assembly sends a spacing abnormality alarm signal to the alarm device in response to determining that the scraper spacing value is greater than a preset threshold value. The spacing abnormality alarm signal may be a signal indicating that "the spacing is too large and the scraper is uneven".

[0103] As an example, the preset threshold may be 0.08.

[0104] In the fourth step, the alarm device performs an alarm operation in response to receiving the abnormal spacing alarm signal, wherein the alarm operation may be displaying warning text or emitting a warning sound.

[0105] As an inventive point of an embodiment of the present disclosure, the above-mentioned scraper flatness detection method solves the technical problem three "waste of computing resources (for example, central processing unit)" raised by the background technology. The factors that lead to the waste of computing resources (for example, central processing unit) are often as follows: In the scraper flatness detection, the manual observation method will lead to a decrease in the accuracy of the detection, while the mathematical modeling method increases the complexity of the calculation. If the above-mentioned factors are solved, the waste of computing resources can be reduced. In order to achieve this effect, the scraper flatness detection device included in the present disclosure can firstly control the scraper transport component to fix the scraper on the scraper clamp. Secondly, the above-mentioned main control chip controls the above-mentioned scraper transport component to install the above-mentioned scraper clamp on the balance bar. In this way, the scraper can be fixed on the scraper detection device included in the scraper flatness detection device. Then, the above-mentioned main control chip controls the above-mentioned scraper transport component to move the crank to control the push pressure gauge and the balance bar to press the above-mentioned scraper down to the marble workbench, and obtain the scraper push pressure value from the above-mentioned push pressure gauge. Thus, the scraper can be controlled to be pressed down, and the pressure value of the scraper can be obtained in time by pushing the pressure gauge. Then, the main control chip stops controlling the scraper transport assembly in response to determining that the scraper push pressure value is within the target range. Thus, the accuracy of the pressure controlling the scraper to be pressed down can be improved to avoid the scraper being damaged due to excessive force. Subsequently, the photosensitive sensor assembly receives a light signal from the light strip, and sends the scraper light transmission signal to the main control chip. Then, the main control chip generates a scraper light illumination value based on the scraper light transmission signal. Thus, it can be determined whether the scraper is flat or damaged based on the size of the light signal passing through the scraper. Then, the main control chip sends a photosensitive abnormal alarm signal to the alarm device in response to determining that the scraper light illumination value is greater than the target threshold. Finally, the alarm device performs an alarm operation in response to receiving the photosensitive abnormal alarm signal. Thus, after determining that the scraper is damaged, an alarm can be issued in time to replace the scraper. Therefore, the scraper flatness detection device can control the scraper to press down to the marble workbench by obtaining the pressure value of the push pressure gauge. Then, the scraper can be illuminated by the light strip. When the scraper is damaged, the intensity change of the light signal can be sensed by the photosensitive sensor. The scraper flatness detection device can confirm that the scraper is damaged and issue an alarm in time. Therefore, there is no need to mathematically model the scraper as a whole, which reduces the complexity of the calculation and thus reduces the waste of computing resources.
