Description

Technical Field

[0001] This application belongs to the field of encoder testing technology, specifically relating to a room temperature testing device for encoders. Background Technology

[0002] In the production process of PCBA encoders, quality compliance testing is a key link to ensure product performance. As a core position and speed detection component in fields such as new energy vehicles, industrial automation equipment, and photovoltaic energy storage systems, the accuracy of PCBA encoder signal output directly determines the operating accuracy and reliability of downstream equipment. Therefore, it is necessary to eliminate unqualified products through strict testing.

[0003] In the current PCBA encoder testing process, workers first connect the PCBA encoder to be tested to a dedicated testing circuit via wires or connectors, ensuring precise alignment between the encoder pins and the signal interface of the testing circuit. Then, the power supply to the testing circuit is turned on to provide operating voltage to the encoder. During the dynamic testing phase, a stepper motor is used to rotate the mechanical transmission components of the PCBA encoder, simulating the encoder's actual operating motion. During this process, the testing equipment collects and analyzes the encoder's static signals (such as pin continuity and static voltage values) and dynamic signals (such as pulse count, frequency stability, and phase difference). Finally, based on preset pass / fail standards, the equipment determines whether the PCBA encoder is qualified. However, existing testing methods still suffer from low efficiency and insufficient automation, making it difficult to fully meet the actual needs of batch testing. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] See also Figure 1-5 As shown, according to this application, a room temperature detection device for an encoder is provided, comprising: Box 1; The testing table 2 has multiple mounting slots for mounting the encoder to be tested, and the bottom of the mounting slot has a hollow hole. Signal generating component 3 is disposed inside the housing 1 and located below the mounting slot, and is capable of generating pulse signals for the encoder to be tested on the detection table 2; Signal collection component 4 is disposed inside the housing 1 and is used to collect the pulse signal generated by the encoder to be tested; The detection system is electrically connected to the signal collection component 4. The detection system detects the pulse signals collected by the signal collection component 4 and feeds back the detection results.

[0023] In this technical solution, the encoder room temperature testing device provided in this application includes a housing 1, a testing platform 2, a signal generation component 3, a signal collection component 4, and a testing system. Multiple mounting slots on the testing platform 2 are used to batch-load encoders to be tested. The signal generation component 3 is positioned below each mounting slot to trigger pulse signals. The signal collection component 4 is responsible for collecting the pulse signals. The testing system completes signal detection and result feedback through electrical connections. This enables batch testing of PCBA encoders, significantly improving testing efficiency.

[0024] Specifically, the operator first places multiple encoders to be tested into the mounting slots of the testing platform 2. Then, the equipment is activated, and the signal generation component 3, located below the mounting slots, operates synchronously. Through a perforated hole, it forms a mechanical or optical connection with the encoder under test, simulating the actual working scenario of the encoder to trigger the generation of pulse signals. Simultaneously, the signal collection component 4 collects the pulse signals output by each encoder under test, avoiding signal delays or interference caused by manual wiring. The collected pulse signals are transmitted to the testing system via electrical connection. The testing system analyzes key parameters such as the number of pulses, frequency stability, and phase difference, compares them with preset pass / fail standards, and directly provides feedback on the test results for each encoder. The entire process eliminates the need for manual connection to the testing circuit or data reading for each encoder individually. Only the initial clamping operation is required to achieve synchronous testing of multiple encoders, avoiding parameter reading errors caused by manual operation and significantly improving testing accuracy.

[0025] Understandably, the number of mounting slots can be flexibly set according to actual production needs. It can be a small batch testing specification of 3-5 slots to suit small and medium-sized enterprises, or a large batch testing specification of 8-12 slots to meet the daily production capacity needs of large factories. As long as each mounting slot is equipped with an independent signal generation component 3, interference-free synchronous testing of multiple encoders under test can be achieved, and signal crosstalk or decreased testing efficiency will not occur due to the increase in the number of mounting slots.

[0026] Understandably, the way the signal generation component 3 works with the encoder under test can be adjusted according to the encoder type. As long as the signal triggering conditions when the encoder is actually working can be simulated and the generated pulse signal meets the detection requirements, there is no need to change the overall structure of the device, which greatly improves the adaptability of the device to different types of PCBA encoders.

[0027] In one feasible embodiment, the signal generating component 3 includes: The first driving component 31 is disposed inside the housing 1; The code disk 32 is disposed on the output end of the first driving member 31 and matches the hollow hole. The first driving member 31 is used to drive the code disk 32 to rotate to trigger the encoder under test to generate a pulse signal.

[0028] In this technical solution, the signal generation component 3 includes a first driving component 31 and a code disk 32. Each mounting slot and the hole on the detection table 2 is equipped with a signal generation component 3 to ensure that each encoder under test can receive a trigger signal that conforms to the actual working scenario, which facilitates the accurate judgment of the subsequent signal collection and detection system.

[0029] The first drive unit 31 is fixed inside the housing 1 and is positioned below the corresponding mounting slot. Its output end is directly connected to the code disk 32. The code disk 32 matches the hollow hole at the bottom of the mounting slot. When the encoder to be tested is placed in the mounting slot, the upper part of the code disk 32 corresponds to the encoder to be tested through the hollow hole. At this time, the first drive unit 31 starts and drives the code disk 32 to rotate at a preset speed. The mechanical movement of the code disk 32 is transmitted to the detection end of the encoder to be tested through the hollow hole, simulating the working state of the encoder to be tested after actual installation, thereby triggering the encoder to generate a pulse signal.

[0030] Understandably, the structure of the code disk 32 can be adjusted according to the encoder type, further expanding the device's compatibility with different types of encoders.

[0031] In one feasible embodiment, the signal collection component 4 includes: The second driving component 41 is disposed inside the housing 1; Fixing plate 42, the fixing plate 42 is disposed on the output end of the second driving member 41; Mounting plate 43, a plurality of mounting plates 43 are disposed on the fixing plate 42, and the number of mounting plates 43 matches the number of mounting slots; The detection pin 44 is disposed on the mounting plate 43. The second driving member 41 is used to drive the detection pin 44 to move up and down so that the detection pin 44 is connected to the signal output terminal of the encoder to be tested.

[0032] The detection needle 44 is a PIN needle.

[0033] In this technical solution, the signal collection component 4 includes a second driving component 41, a fixing plate 42, a mounting plate 43, and a detection pin 44. The second driving component 41 is fixed inside the housing 1, and its output end is directly connected to the fixing plate 42, which can drive the fixing plate 42 to move stably in the vertical direction. The detection stage 2 on the fixing plate 42 corresponds to the number of mounting slots, and multiple mounting plates 43 are set synchronously to ensure that the number of mounting plates 43 corresponds to the number of mounting slots. The detection pin 44 mounted on each mounting plate 43 is pre-calibrated to the position corresponding to the signal output end of the encoder to be tested. When the encoder to be tested is installed in the mounting slot, the second driving component 41 is started and drives the fixing plate 42 to move downward, thereby causing the detection pins 44 on all mounting plates 43 to descend synchronously until they are in close contact with the signal output end of each encoder. At this time, the detection pin 44 stably transmits the pulse signal generated by the encoder to the subsequent detection system.

[0034] Understandably, the drive stroke of the second drive unit 41 can be set according to the thickness of the encoder, as long as the detection pin 44 can fully contact the signal output end without excessively squeezing the encoder. This can be achieved by adjusting the stroke knob or setting the software parameters, making the operation convenient.

[0035] In some examples, a position sensor can be installed on the fixed plate 42 to monitor the descent height of the detection pin 44 in real time. When the detection pin 44 reaches the preset docking position, the position sensor sends a stop signal to the second drive unit 41 to avoid damage to the components due to over-driving.

[0036] In one feasible embodiment, a third driving component 5 and a guide rail 6 are provided between the housing 1 and the testing platform 2. The guide rail 6 is provided between the housing 1 and the testing platform 2, and the third driving component 5 is provided between the housing 1 and the testing platform 2 to drive the testing platform 2 to move horizontally.

[0037] In this technical solution, a third drive unit 5 and a guide rail 6 are installed between the housing 1 and the testing platform 2. The guide rail 6 is parallel to the bearing plane inside the housing 1 and the bottom of the testing platform 2. One end of the third drive unit 5 is fixed to the inner wall of the housing 1, and the other end is connected to the side of the testing platform 2. It can drive the testing platform 2 to move smoothly along the guide rail 6 according to preset instructions. When it is necessary to clamp the encoder to be tested, the third drive unit 5 drives the testing platform 2 to move along the guide rail 6 to the vicinity of the operating window of the housing 1. The operator can then place the encoder into the mounting slot to avoid collision between the hand and the detection needle 44 inside the housing. After installation, the third drive unit 5 is activated again, driving the testing platform 2 to move along the guide rail 6 to the testing position. At this time, the hollow hole at the bottom of the mounting slot is aligned with the code disk 32 of the signal generating component 3, and the detection needle 44 can be smoothly connected to the signal output end of the encoder to be tested to ensure that the testing conditions are met.

[0038] In one feasible embodiment, positioning pins 7 are provided on the testing platform 2 and on both sides of the mounting groove, the positioning pins 7 being used to fix the encoder to be tested.

[0039] In this technical solution, positioning pins 7 are set on both sides of the mounting slot of the test platform 2. The positioning pins 7 are usually cylindrical or conical in shape and are vertically fixed to the surface of the test platform 2 on both sides of the mounting slot. The number and position of the positioning pins 7 on each side must match the positioning holes of the encoder to be tested. When the operator puts the encoder to be tested into the mounting slot, the positioning holes of the encoder to be tested can be directly fitted into the positioning pins 7 on both sides. The positioning pins 7 prevent the encoder to be tested from shifting due to vibration, ensuring that the hollow hole at the bottom of the mounting slot is always aligned with the code disk 32, and that the test needle 44 maintains stable contact with the signal output end of the encoder to be tested.

[0040] Understandably, the top of the positioning pin 7 can be chamfered to form a smooth guide slope. When the positioning hole of the encoder to be tested is aligned with the positioning pin 7, the slope can guide the positioning hole to quickly fit into the positioning pin 7, avoiding clamping jams caused by slight misalignment between the positioning hole and the positioning pin 7. This is especially suitable for high-frequency clamping operations during batch testing, further improving the ease of operation.

[0041] In one feasible embodiment, the first drive element 31 is a stepper motor.

[0042] In one feasible embodiment, the second drive member 41 and the third drive member 5 are cylinders.

[0043] In one feasible embodiment, a display screen 8 is provided on the housing 1, and the display screen 8 is electrically connected to the detection system.

[0044] An alarm is installed on the housing 1, and the alarm is electrically connected to the detection system.

[0045] In this technical solution, a display screen 8 and an alarm are electrically connected to the detection system on the housing 1. After the detection system completes the pulse signal analysis, it synchronously transmits the detection results (such as pass / fail status, specific parameter deviation, and detection time) of each encoder to be tested to the display screen 8. The display screen 8 presents the result of a single encoder using an independent display unit, such as green for pass and red for fail. Operators do not need to operate the equipment; they can intuitively obtain the detection information of all encoders to be tested through the display screen 8. The alarm is installed on the top or side of the housing 1. When the detection system determines that any encoder to be tested is unqualified, it immediately sends a trigger signal to the alarm. The alarm issues a warning through sound or light, so even if the operator does not see the display screen 8 in real time, they can quickly know about the detection anomaly through the sound and light signals, preventing unqualified products from flowing into the next process.

The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
