Description

Technical Field

[0001] The utility model relates to the technical field of encoders, and specifically relates to a dual-output encoder dedicated for a digital display device. Background Technique

[0002] Encoders can be divided into two categories: incremental and absolute according to the working principle. The incremental encoder converts displacement into periodic electrical signals, and then converts these electrical signals into counting pulses, and uses the number of pulses to represent the magnitude of displacement. Each position of the absolute encoder corresponds to a definite digital code. Therefore, its display value is only related to the starting and ending positions of the measurement, and has nothing to do with the intermediate process of the measurement.

[0003] Encoders are mainly applied in OEM industries such as elevators, machine tools, motor supporting, textile / packaging / printing machinery, heavy machinery, and medical machinery. The application range is wide and the prospect is very promising.

[0004] Therefore, for different industries and different application scenarios, there are also many encoders for special situations. The utility model puts forward a new idea for the problem of equipment failure caused by collecting signals on the same encoder for different devices at the same time, that is, to make the same encoder be able to completely independently realize the functions that two encoders can achieve in the electrical part, that is, it can supply two independent power supplies, have independent pulse numbers, and independent output modes, and then proposes a dual-output encoder dedicated for a digital display device. Content of the Utility Model

[0006] Therefore, the purpose of the utility model is to provide a dual-output encoder dedicated for a digital display device. The two outputs can be independently powered by two independent power supplies, avoiding the phenomenon that one of the outputs cannot be compatible when different acquisition systems provide different power supplies. And for different acquisition systems, the required output modes of the encoders are different. The dual-output encoder of the utility model can provide independent output modes to meet the needs of various acquisition systems.

[0029] In order to make the purpose, technical solution, and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail with reference to the accompanying drawings.

[0030] The present utility model provides a dual-output encoder dedicated for a digital display device. Please refer to Figure 1 , which includes 1 main body 1, main shaft 2, bearing 3, code disk support 4, light-emitting tube seat 5, light-emitting 6, code disk 7, magnet steel sleeve 8, magnet steel 9, second circuit board 10, round hole 10-1, photovoltaic cell 11, second circuit board 12, Hall chip 13, housing 14, first support column 15, and second support column 16;

[0031] Please continue to refer to Figure 1-2 , the housing 14 as the connection base frame, and the main body 1 is connected inside the housing 14;

[0032] There are two bearings 3 rotatably connected to the main body 1, and a main shaft 2 is key-connected inside the bearings 3;

[0033] A code disk holder 4, a code disk 7, and a magnet steel sleeve 8 are sequentially sleeved on the main shaft 2. A magnet steel 9 is embedded in the magnet steel sleeve 8, and the magnet steel 9 is pressed on the main shaft 2;

[0034] A light-emitting tube base 5 is connected to the main body 1 through a positioning bolt, and a light-emitting tube 6 is screwed inside the light-emitting tube base 5;

[0035] A first circuit board 10 is connected inside the housing 14. A round hole 10-1 is provided at the center of the first circuit board 10 for the magnet steel sleeve 8 to pass through;

[0036] The first circuit board 10 is embedded in the main body 1 through a second support column 16 (the second support column is welded inside the housing). A second circuit board 12 is also welded inside the housing 14. The second circuit board 12 is arranged corresponding to the upper part of the first circuit board 10. The second circuit board 12 is embedded on the first circuit board 10 through a first support column 15;

[0037] Furthermore, a photovoltaic cell 11 is welded on the first circuit board 10. The photovoltaic cell 11 and the light-emitting tube 6 are on the same optical radius and correspond to each other. A Hall chip 13 is welded on the second circuit board 12. The Hall chip 13 is completely corresponding to the magnet steel 9, and there is a gap in the middle and they do not contact each other.

[0038] Working principle: When the encoder is powered on, the light-emitting tube 6 is lit and the entire circuit board starts to work. The main shaft 2 rotates under the drive of an external force (such as a motor, etc.). Then the code disk 7, the magnet steel 9, and the main shaft 2 rotate synchronously. When the code disk 7 rotates, the light emitted by the light-emitting tube 6 passes through the window on the code disk 7 and becomes regular light that is received by the photovoltaic cell 11. After being processed by the subsequent circuit, a regular signal is output. When the code disk 7 rotates, the magnet steel 9 rotates synchronously. At this time, the Hall chip 13 receives the regular magnetic field of the NS pole transformation transmitted from the magnet steel 9 and generates a regular electrical signal. After being processed by the subsequent circuit, a regular signal is also output. Since the number of windows set on the code disk can be adjusted, and the number of pulses can also be adjusted through the program on the Hall chip 13. Also, because the two outputs are designed on two independent circuit boards, their output methods and supply voltages can also be independent.

[0039] Although the present utility model has been described above with reference to the embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the features in the embodiments disclosed by the present utility model can be combined with each other in any way, and the exhaustive description of these combinations is not given in this specification only for the consideration of saving space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
