Description

Technical Field

[0001] The utility model specifically relates to the technical field of encoder power-off signal output, in particular to an encoder device with a power-off signal output structure. Background Art

[0002] An encoder is a device that compiles and converts signals or data into a signal form that can be used for communication, transmission and storage. The encoder converts angular displacement or linear displacement into electrical signals. The former is called a code disk, and the latter is called a yardstick. According to the readout method, encoders can be divided into contact and non-contact types; according to the working principle, encoders can be divided into incremental and absolute types. Incremental encoders convert displacement into a periodic electrical signal, and then convert this electrical signal into a counting pulse, using the number of pulses to represent the size of the displacement.

[0003] Encoders are now important control devices in production equipment. With the advancement of technology, most companies now adopt fully automated production. In this way, a large number of encoders are needed to control the equipment in production. The equipment works effectively through the pulses of the encoder.

[0004] The robot arms used in the production lines of enterprises now complete the corresponding actions in the pulse signals sent by the encoders through the control of encoders. However, when the input signal is powered off, the traditional encoder cannot effectively complete the work within the pulse, so after the power is restored, the equipment will be damaged.

[0005] After searching, Chinese patent publication number CN202220068501.3 discloses an absolute encoder based on RS485 communication power-off memory; including a microcontroller, a communication interface is connected to the microcontroller, a data storage device is connected to the microcontroller, and an input voltage detector is connected to the microcontroller;

[0006] Although the encoder in the above patent can effectively achieve the effect of power-off memory; however, in the above patent, when the voltage inside the input circuit is too low, it is necessary to detect the voltage through a voltage detection device. In this way, during the detection process, the pulse signal emitted by the encoder will be interrupted. In this way, even if the power is supplied again, only the next pulse signal can be realized, so that the previous pulse signal cannot completely complete the work.

[0007] In response to the above situation, we provide an encoder device with a power-off signal output structure. In this device, a battery is arranged inside the shell, which can effectively ensure that when the input signal is powered off, the battery is connected to the memory control board in a short time, and the normal operation of the equipment is achieved through the memory control board. The pulse signal emitted by the encoder will not be interrupted, and the effective equipment completes the pulse limiting instruction. When the power is off, the offset angle of the grating plate is recorded through the memory control board. After the power is restored, the grating plate returns to the angle before the power is off. Utility Model Content

[0008] The purpose of the utility model is to provide an encoder device with a power-off signal output structure, in which a battery is arranged inside the shell, so that the input signal can be effectively guaranteed to be connected to the memory control board in a short time when the power is off, and the normal operation of the equipment is realized through the memory control board. The pulse signal emitted by the encoder will not be interrupted, and the effective equipment completes the pulse limit instruction. When the power is off, the offset angle of the grating plate is recorded by the memory control board to solve the problems of the above-mentioned background technology.

[0009] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] An encoder device with a power-off signal output structure comprises an encoder; the encoder comprises a housing; the interior of the housing is provided with a cavity; a battery is fixedly mounted on a side plate inside the housing; a light source is fixedly mounted on one side of the battery; the battery is electrically connected to a memory control board;

[0014] As a further technical solution of the utility model, a connecting pipe is integrally provided at the bottom of the shell; a data line runs through the inside of the connecting pipe, and the data line is connected to the memory control board.

[0015] As a further technical solution of the utility model, the battery and the data line are connected in parallel with the memory control board; and the output terminal of the memory control board is connected with the light source.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model, when in use, transmits a signal to the memory control board through the data line, so that the encoder sends a specified pulse signal to the device and the device works accordingly. During the working process, when the data line is powered off, the memory control board is powered by a battery installed inside the shell to ensure that the pulse signal generated by the encoder will not be interrupted, and the device can effectively complete the specified pulse instruction. When the power is off, the memory control board effectively stores and memorizes the corresponding deflection angle of the grating plate. After the data line is powered on again, the battery stops working, and the output state is changed to the input state (and charged). After the data line is powered on again, the memory control board is used to reset the deflection angle of the grating plate to the position before the power is off.

[0030] By adopting the above technical solution, the inside of the housing 10 is sealed by installing the cylinder 20 and the housing 10, so as to prevent the position of the pulse signal of the encoder from being offset when the pulse signal is generated, and effectively ensure the control of the encoder on the equipment;
