Description

Technical Field

[0001] The utility model relates to the technical field of encoder signal detection, in particular to an encoder signal detection device. Background Art

[0002] Incremental photoelectric encoders are representative photoelectric displacement sensors for measuring angular displacement. They are widely used in the fields of industry and science and technology. Photoelectric encoders can obtain the rotation angle or speed information of the measured shaft by processing the output pulse signals through the conversion circuit. Photoelectric encoders have the advantages of long average mechanical life, high resolution, strong anti-interference ability, long signal transmission distance, and high reliability. The technical indicators of photoelectric encoders include the number of pulses output by the encoder for one rotation, the duty cycle of each pulse signal, and the phase relationship between the pulses.

[0003] The prior art is to use an oscilloscope to directly observe the output pulse waveform of the encoder, and estimate the encoder performance indicators such as the phase difference and duty cycle of each pulse through the coordinate transformation on the oscilloscope; in addition, the prior art does not make a test device specifically for directly reading the encoder signal, and most of them are auxiliary installation equipment or fixtures for encoder testing, and the signal detection is still carried out by other means; and the auxiliary equipment for the existing encoder test is large in size, the equipment is bulky as a whole, and is not delicate and beautiful. The prior art does not have an automatic storage function for the results of the encoder test.

[0004] Therefore, the prior art has the following deficiencies:

[0005] 1. When using an oscilloscope to directly observe the encoder output signal waveform, the calculation process is time-consuming and labor-intensive, and the calculation result has a large error. This is because the waveform range that the oscilloscope can observe is limited. For example, when the motor rotates 10 circles, it is impossible to observe and calculate the pulse data of 10 circles, and the quality of the observed waveform is also related to the performance of the oscilloscope;

[0006] 2. There are many types of encoder signal output, including single-ended, differential, AB\ABZ\ABZUVW\UVW, which require very high accuracy in signal detection. At the same time, it must be able to detect multiple types of encoder signals. During the detection process, the stability and reliability of the equipment operation must be guaranteed, which greatly increases the difficulty and cost of the research and development of the detection equipment.

[0007] 3. The existing technology for testing encoder signals is difficult to integrate into one device. Generally, it is completed by multiple detection devices and some auxiliary devices working together, and the integration is low.

[0008] 4. When testing encoders in large quantities in actual production, the amount of test data is huge, and it is difficult to keep a record of the test results for each product. When a problematic product appears later, the original test records cannot be traced. Utility Model Content

[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0043] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0044] An encoder signal detection device, such as Figures 1 to 9 As shown, it includes a box body 4, on which is provided,

[0045] The interface board 1 is arranged on the back plate of the box body 4, and the interface board 1 is provided with:

[0046] The motor control signal input interface 101 is located at the upper left of the interface board 1 and is connected to the external motor driver 7 to receive the motor control signal;

[0047] The encoder single-ended signal input interface 102 is provided at the lower right of the motor control signal input interface 101 and is used to connect an external single-ended encoder;

[0048] The encoder differential signal input interface 103 is provided on the right side of the encoder single-ended signal input interface 102 and is used to connect an external differential encoder;

[0049] The encoder signal terminal 107 is provided at the bottom of the interface board 1 and is used to connect an external differential encoder;

[0050] The signal processing board 2 is arranged inside the back plate of the box body 4, connected to the encoder signal terminal 107, the motor signal output terminal 106 and the serial communication terminal 108 of the interface board 1, and receives the output signal of the encoder and the motor control signal.

[0051] Specifically, the utility model can directly detect the encoder output signal without the aid of an oscilloscope. The signal processing board 2 is the signal processing device of the utility model. The encoder single-ended signal input interface 102 is used to connect an external single-ended encoder. The encoder differential signal input interface 103 and the encoder signal terminal 107 are both used to connect an external differential encoder, which can be selectively connected according to the encoder model.

[0052] During the test of the utility model, the number of test turns can be customized, and the detection device will capture and analyze all the data within the test turns. After the test is completed, the test data of the encoder signal's duty cycle, phase difference, pulse number and other related performance indicators can be directly viewed in the detection device. In addition, the utility model detection device can make judgments based on the customized allowable deviation, and the tester can directly see whether the performance of the test encoder is qualified. The entire detection process is accurate and convenient, which greatly improves the test efficiency.

[0053] The detection equipment of the utility model is highly compatible with the test of various incremental photoelectric encoders, and meets the test requirements of various types of existing encoder signal outputs. The differential signal can be directly detected, and the single-ended signal can be detected internally by the device without the need for other external auxiliary test equipment or test boards.

[0054] The detection equipment has high reliability and accuracy in testing the performance index of the encoder signal, which can meet the detection of the encoder in actual production. When the utility model is used for encoder testing on the production line, the encoder with continuous testing of more than 3000 PCS still maintains high accuracy and high reliability, and the equipment operates normally continuously.

[0055] The utility model is simple to operate and has simple wiring. There is no learning cost for production line operators to use it, and it is easy to get started. It only takes about 30 seconds to complete the test of 1PCS using this equipment, and the test data is complete and accurate; while the traditional test using an oscilloscope takes a long time, generally taking about 2 minutes to 3 minutes to complete the test of 1PCS, and the amount of data to be viewed is limited, and the test result has a large error.

[0056] The overall appearance of the detection equipment of the utility model is exquisite and beautiful, and the weight is light. It can meet the needs of equipping a production line with multiple devices. In industrial production, it can greatly improve production efficiency, reduce testing links, and streamline production line operators.

[0057] The automatic data saving function inside the testing equipment greatly facilitates the archiving of test results, provides strong test data support for the tracing of problematic products that may arise in the future, and facilitates review and research.

[0058] In a preferred embodiment, the encoder signal terminal 107 includes an A-phase signal terminal, a B-phase signal terminal, a Z-phase signal terminal, a U-phase signal terminal, a V-phase signal terminal and a W-phase signal terminal for receiving encoder differential signals. The encoder single-ended signal input interface 102 receives a single-ended encoder signal; the encoder differential signal input interface 103 receives a differential encoder signal.

[0059] Specifically, the encoder signal terminal 107 includes a first row of terminals for detecting ABZ signals, and the first row of terminals includes six terminals A+, A-, B+, B-, Z+, and Z-. The encoder signal terminal 107 also includes a second row of terminals for detecting UVW signals, and the second row of terminals includes six terminals U+, U-, V+, V-, W+, and W-.

[0060] Specifically, the detection equipment provided by the utility model can meet the encoder detection of various signal types and has encoder detection functions of various signal types. Differential AB, ABZ, ABZUVW, UVW signals and single-ended AB, ABZ, ABZUVW, UVW signals can be detected. The test precision and accuracy are high, and the detection equipment can still operate normally under continuous testing.

[0061] Specifically, the detection device of the utility model has a high internal integration, and does not require other devices such as oscilloscopes, signal generators, etc. As long as the motor M equipped with the encoder rotates normally, the encoder signal can be detected, the wiring is simple, and the overall appearance of the device is exquisite and beautiful.

[0062] The testing equipment can automatically save the test results of each 1PCS encoder, and can easily export them to a USB flash drive to view the data on a computer for later tracing.

[0063] Specifically, the duty cycle acquisition principle of ABZ and UVW is as follows: the MCU timer input is used for acquisition, the rising and falling edges of the acquisition signal are timed, and the signal duty cycle value is obtained by dividing the high level time by the high level and low level time (signal cycle). After multiple samplings, the maximum, minimum, average and maximum deviation of the duty cycle are calculated. When the maximum deviation exceeds the allowable deviation set by the software, it is unqualified, and when it is within the allowable deviation range set by the software, it is qualified.

[0064] The number of ABZ and UVW pulses is the number of signal pulses included in one circle of the encoder. The acquisition principle is: there is only one Z pulse signal in one circle, and one Z pulse is used to mark one circle in the software. Every time an ABUVW signal comes, the pulse is counted for one circle, and the count value is the number of ABUVW pulses. After counting multiple circles, the maximum value, minimum value, average value and maximum deviation of the pulse number are calculated. When the maximum deviation exceeds the allowable deviation set by the software, it is unqualified. When it is within the allowable deviation range set by the software, it is qualified.

[0065] AB, UV, VW, WU phase difference is the counting time difference of the rising edge of the corresponding pulse signal, which is compared with one cycle to calculate its phase degree. After multiple acquisitions, the maximum, minimum, average and maximum deviation of the phase difference are calculated. When the maximum deviation exceeds the allowable deviation set by the software, it is unqualified, and when it is within the allowable deviation range set by the software, it is qualified.

[0066] The motor control signal input interface 101 can be connected to a stepper or servo driver, and the lead wires have a direction control signal and a speed control signal. Direction control signal: forward rotation is a high-level output, and reverse rotation is a low-level output. The output voltage is between 4V and 5V; speed control signal: when the option is a stepper motor, different speeds output pulses with different frequencies and a duty cycle of 50%, and the higher the speed, the higher the frequency; when the option is a BLDC servo motor, different speeds output pulses with fixed frequencies and different duty cycles, and the higher the speed, the higher the duty cycle. The angular displacement is controlled by controlling the number of pulses, thereby achieving the purpose of accurate positioning; at the same time, the speed and acceleration of the motor M can be controlled by controlling the pulse frequency, thereby achieving the purpose of speed regulation.

[0067] The encoder signal detection device has four test channels, corresponding to eight encoder signal output tests, namely differential: AB signal, ABZ signal, ABZUVW signal, UVW signal; single-ended: AB signal, ABZ signal, ABZUVW signal, UVW signal.

[0071] 2500-line encoder: motor speed does not exceed 1200 rpm;
