Traditional inspection methods require workers to connect the stepper encoder to the detection circuit and turn on the power supply, and cooperate with the stepper motor to perform various static and dynamic signal detection. This method has problems such as high inspection difficulty, limited manual inspection items and low accuracy. This utility model proposes a new solution to the above problems. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0019] This application provides a stepper encoder detection device, such as... Figures 1-7As shown, the system includes a worktable 1, a detection module 2, a light-shielding module 3, and a detection mechanism 6. The worktable 1 has a product slot for positioning encoder products to be inspected. The detection module 2 is mounted on the worktable 1 and includes an electric cylinder 21 and a detection module 22. The electric cylinder 21 drives the detection module 22 to reciprocate for electrical connection or disconnection with the encoder product to be inspected. The light-shielding module 3 is mounted on the worktable 1 and includes a transmission mechanism 31 and a light-shielding baffle 32. The transmission mechanism 31 drives the light-shielding baffle 32 to reciprocate to adjust the degree of light blocking on the encoder product to be inspected. The detection mechanism 6 is signal-connected to the detection module 2 and the light-shielding module 3 to acquire the electrical characteristic parameters of the encoder product to be inspected.

[0020] The stepper encoder testing device provided in this embodiment can accurately establish an electrical connection between the encoder pins and the encoder product under test by the testing module 22 driven by the electric cylinder 21. The light-shielding baffle 32 continuously adjusts the light-shielding range of the encoder product under test by stepping, simulating the light change state of the encoder in the actual working environment. The testing mechanism 6 collects electrical signal parameters at different light-shielding stages in real time, fully covering static and dynamic performance tests, effectively verifying the response characteristics of the encoder in light-sensitive scenes, and significantly improving the testing efficiency, accuracy and precision.

[0021] In one possible implementation, such as Figure 4 As shown, the detection module 22 includes a detection PIN pin, which is positioned facing the encoder product under test and is used to make contact with the pins of the encoder product under test to achieve electrical connection.

[0022] The detection module 22 establishes a stable and reliable electrical connection path by detecting the precise contact of the PIN pins toward the pins of the encoder product under test, ensuring the stability of the detection signal during transmission. The detection module 22 can accurately obtain the electrical characteristic parameters of the encoder product under test under different working conditions. At the same time, it works with the reciprocating motion of the electric cylinder 21 to achieve automated docking and separation, which not only ensures detection efficiency, but also avoids problems such as poor contact or pin damage caused by manual operation, significantly improving the standardization of the detection process and the accuracy of the results.

[0023] In one possible implementation, such as Figure 2 and Figure 3 As shown, the transmission mechanism 31 is an electric transmission device that drives the light-shielding baffle 32 to reciprocate at a preset step distance accuracy to adjust the light-shielding state of the encoder product to be inspected.

[0024] The transmission mechanism 31 uses an electric transmission device to drive the light-shielding baffle 32 to reciprocate. The light-shielding state is precisely controlled by a preset step distance accuracy. During the test, the light-shielding baffle 32 gradually changes the shielding position according to the set step distance, so that the encoder product under test experiences test environments with different light intensities in sequence. The test mechanism 6 simultaneously collects the electrical signal parameters corresponding to each shielding stage, which not only verifies the response characteristics of the encoder under gradually changing light conditions, but also ensures the stability and repeatability of the dynamic test process. It effectively simulates the impact of light intensity changes on encoder performance in actual applications and provides reliable test conditions for evaluating the adaptability of photosensitive elements.

[0025] Furthermore, the preset step size accuracy can reach 0.06mm-0.1mm. The transmission mechanism 31 drives the light-shielding baffle 32 with a preset step size accuracy of 0.06mm-0.1mm, achieving sub-millimeter-level precise control of the light shading state. During the detection process, the light-shielding baffle 32 changes the shading position step by step with small step sizes, allowing the encoder to experience light change gradients on the order of 0.06mm to 0.1mm. This simulates the subtle light fluctuations that may be encountered in actual applications, while avoiding detection blind spots caused by excessive step size. The detection mechanism 6 can simultaneously collect the electrical signal parameters corresponding to each shading stage, ensuring complete coverage of the encoder's photosensitive response characteristics and improving the stability and reliability of testing under complex lighting conditions.

[0026] The transmission mechanism 31 of this stepper encoder detection device can be adjusted to suit different detection requirements by changing the preset step size accuracy. When the step size accuracy is greater than 0.1mm, the motion gradient of the light-shielding baffle 32 increases accordingly, making it suitable for encoders with low sensitivity to changes in lighting or scenarios requiring rapid detection.

[0027] In one possible implementation, such as Figure 2 and Figure 3 As shown, the light-shielding module 3 also includes a bracket 33, the output end of the transmission mechanism 31 is connected to the bracket 33, the light-shielding baffle 32 is set on the bracket 33, and the transmission mechanism 31 adjusts the position of the light-shielding baffle 32 through the bracket 33.

[0028] Among them, the light-shielding module 3 rigidly connects the transmission mechanism 31 and the light-shielding baffle 32 through the bracket 33, so that the driving force of the transmission mechanism 31 can be efficiently transmitted to the light-shielding baffle 32, ensuring that its motion trajectory is synchronized with the preset step distance, thus ensuring the stability of the light-shielding baffle 32 in reciprocating motion. The structure of the bracket 33 ensures that the light-shielding baffle 32 always maintains a high correspondence with the encoder product to be inspected, thus ensuring the accurate positioning of light blocking.

[0029] In one possible implementation, such as Figures 1-6As shown, the stepper encoder testing device also includes a mounting frame 5, which is set on the workbench 1 and located between the encoder product to be tested and the light shielding module 3. The mounting frame 5 has a clearance hole 51 for the light shielding baffle 32 to pass through.

[0030] Among them, the clearance hole 51 on the mounting bracket 5 provides an interference-free movement channel for the light shield 32, ensuring that the light shield module 3 can maintain the stability of the distance between itself and the encoder product under inspection when adjusting the light shielding, and avoid the risk of collision between mechanical structures, so that the movement trajectory of the light shield 32 corresponds precisely to the light-receiving area of ​​the encoder product under inspection.

[0031] In one possible implementation, such as Figure 1 As shown, the light-shielding module 3 also includes a housing 34, which is fitted onto the transmission mechanism 31, the light-shielding baffle 32, and the bracket 33.

[0032] The light-shielding module 3 encloses the transmission mechanism 31, the light-shielding baffle 32, and the bracket 33 entirely through the housing 34, forming an independent optical isolation environment. The housing 34 effectively blocks external stray light interference, ensuring that the illumination conditions during the test are precisely controlled only by the light-shielding baffle 32, thereby improving the reliability of the test data. At the same time, the housing 34 protects the internal moving parts, preventing dust contamination or accidental contact from affecting the transmission accuracy and ensuring the stability of the internal structure of the light-shielding module 3.

[0033] In one possible implementation, the detection mechanism 6 collects voltage parameters in real time during the stepping process of the light-shielding baffle 32, and detects current and voltage parameters in both the fully light-shielding and fully light-incident states.

[0034] The testing mechanism 6 dynamically tracks the stepping process of the light-shielding baffle 32, enabling full-condition monitoring of the electrical parameters of the encoder under test. Real-time voltage parameters are acquired during the movement of the light-shielding baffle 32, capturing the transient characteristics of the encoder's response to changes in illumination. Simultaneous detection of current and voltage parameters under both complete light-shielding and complete light-incident extreme conditions allows for accurate evaluation of the encoder's operational stability and energy consumption under extreme lighting conditions. Segmented testing ensures continuous analysis of the dynamic response, and multi-parameter joint detection at key state points comprehensively verifies the encoder's overall performance under different light intensities.

[0035] In one possible implementation, the detection mechanism 6 processes the motion pulses of the transmission mechanism 31 through a microcontroller. On the one hand, the microcontroller converts the motion pulses into precise displacement commands for the light-shielding baffle 32, synchronously driving the detection module 22 to complete the acquisition of electrical parameters; on the other hand, it performs a closed-loop comparison between the actual motion data fed back by the sensor and the preset pulses, and ensures accuracy through a two-way verification mechanism of pulse-feedback.

[0036] In one possible implementation, such as Figure 1 As shown, the testing mechanism 6 is equipped with a display screen. The electric cylinder 21 and the transmission mechanism 31 are operated through the display screen. The test results are displayed on the display screen. If the parameters are qualified, green is displayed; if they are unqualified, red is displayed and an audible alarm is triggered.

[0037] Among them, the testing mechanism 6 realizes human-computer interaction and status visualization through an integrated display screen. Operators can directly control the start and stop of the electric cylinder 21 and the transmission mechanism 31 and set parameters through the touch interface, which simplifies the testing process.

[0038] The system drives the light-shielding baffle 32 to move precisely at a preset step distance. The detection circuit collects the encoder electrical parameters at each step position of the light-shielding baffle 32 in real time and compares them with the preset standard values. When all detection parameters meet the standards, the system determines that the product is good and displays it intuitively with a green label. If there are abnormal parameters, a red warning interface and audible alarm are immediately triggered. This not only ensures the consistency of detection accuracy, but also greatly improves the sorting efficiency of good products on the production line through visual interaction, significantly improving detection efficiency and reliability.
