Description

Technical Field

[0001] The utility model relates to the technical field of automated testing equipment, in particular to a micro encoder testing mechanism. Background Art

[0002] An encoder is a device that compiles and converts signals, such as bit streams or data, into a signal form that can be used for communication, transmission, and storage. Encoders typically operate based on the conversion of physical quantities, utilizing certain physical properties to capture raw signals and convert them into digitally encoded pulse outputs. Different types of encoders utilize different properties.

[0003] For example, some encoders can use the giant magnetic effect or Hall effect to sense the rotation of the magnetic field of a radially magnetized cylindrical magnet to read the angle of the magnet's rotation. This allows the magnet to be mounted on the motor shaft, and the motor's rotation angle can be read. To improve the encoder's reading accuracy, the encoder must be tested before use to ensure proper operation. Currently, testing an encoder requires connecting the encoder's wiring to test equipment; then, by rotating the encoder shaft and observing the waveform on the test equipment, the encoder can be determined to be functioning properly.

[0004] Based on this, patent document CN114047811A discloses an encoder testing machine, which includes a conveyor, an upper test die, and a lower test die. The encoder is mounted in a positioning die holder. When the encoder moves to the band detection position, the upper test die, located on one side of the conveyor, secures the encoder in the positioning die holder and connects a second probe to the encoder's terminal pins. The shaft head clamping device of the lower test die clamps the encoder's button, which is then rotated by a first rotating device for testing. This patent document provides an implementation of an encoder testing machine that can perform band detection on encoders equipped with buttons.

[0005] However, the encoder tester disclosed above still has the technical problem of insufficient applicability. Specifically, at present, the equipment used to detect encoders on the market can generally be divided into two types. One is a fixed platform type, in which the encoder is placed on the test equipment, and the motor on the test equipment drives the encoder shaft to rotate, so that the encoder can be tested. In this solution, since the encoder needs to be placed on the platform, this fixed platform test equipment can only test small-volume encoders. The other test equipment is a handheld type. After connecting the test equipment to the encoder, the encoder can be tested by manually rotating it. This detection equipment can test larger encoders. However, since the speed of manually rotating the encoder is slow, the detection effect cannot be achieved. Therefore, there is a need for a highly applicable test platform to facilitate the testing of encoders of different sizes. Utility Model Content

Furthermore, both micro-encoders can be connected to an external PC host computer so that the signal analysis software pre-installed on the external PC host computer can read and identify the signals output by the two sets of micro-encoders. Afterwards, the drive mechanism 4 is powered and started, so that its rotational power can be transmitted to the encoder connected to the first encoder connection structure 2 through the first transmission connection structure 5; at the same time, the second transmission connection structure 6 can realize the linkage between the first transmission connection structure 5 and the second transmission connection structure 6 under the linkage of the shaft adjustment structure 7, thereby enabling the micro encoder connected to the second encoder connection structure 3 to obtain rotational power and operate; at this time, the two groups of micro encoders can simultaneously output action signals, and the external signal analysis software can compare the two signals to determine whether the output data of the tested encoder meets the requirements, and further determine whether the tested encoder product is qualified.

[0036] Furthermore, when the first relay transmission wheel 504 is driven by the first transmission belt 506, it can transmit power to the second gear transmission unit 707 via the first gear transmission unit 706, and then the second gear transmission unit 707 drives the second relay transmission wheel 604. The second relay transmission wheel 604 can drive the second transmission belt 605, which in turn drives the second transmission wheel 603.
