Description

Technical Field

[0001] The utility model relates to the technical field of encoders, in particular to an encoder with a shielding function. 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. According to the working principle, encoders can be divided into two types: incremental and absolute. 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. Each position of an absolute encoder corresponds to a certain digital code, so its indication is only related to the starting and ending positions of the measurement, but not to the intermediate process of the measurement.

[0003] After searching, a Chinese patent with publication number CN220123355U discloses an encoder with a shielding function, including a shielding shell body, a sealing end cover is arranged at the rear end of the shielding shell body, and a circular sealing groove is opened at the rear end of the shielding shell body. The user passes one end of the locking bolt through the connecting through hole and screws it into the inside of the threaded hole, so as to facilitate the fixing of the sealing end cover. When the locking bolt fixes the sealing end cover, the side of the sealing end cover close to the shielding shell body will squeeze the sealing gasket, so as to further improve the sealing effect between the shielding shell body and the sealing end cover. The device has a simple structure and is easy to operate. The positioning block is provided to facilitate the positioning and installation of the sealing end cover. The circular sealing plug and the sealing gasket are provided to effectively seal the shielding shell body, so that the external electromagnetic field will not affect the encoder body inside the shielding shell body.

[0004] The above patent has the following shortcomings: the encoder with shielding function is easy to affect its performance due to the internal temperature rise of the electromagnetic encoder when it is working, and it is easy to be damaged when the temperature is too high. The device has problems such as poor heat dissipation effect, inability to dissipate heat continuously, and easy accumulation of dust. In view of this, we propose an encoder with shielding function.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] 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. According to the working principle, encoders can be divided into two types: incremental and absolute. 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. Each position of an absolute encoder corresponds to a certain digital code, so its indication is only related to the starting and ending positions of the measurement, but not to the intermediate process of the measurement.

[0032] Since the internal temperature of the electromagnetic encoder rises when it is working, it is easy to affect its performance. It is easy to be damaged when the temperature is too high.

[0044] like Figure 3 As shown, the shape of the clamping block 46 is arc-shaped, and the clamping block 46 is in contact with the encoder body 2.

[0045] Specifically, such a configuration can improve the clamping stability of the clamping block 46 on the encoder body 2 .

[0046] like Figure 2 As shown, a fan 6 is fixedly connected to one side of the fixing plate 41 .

[0047] Specifically, such an arrangement can improve the heat dissipation of the device, and at the same time can prevent dust from clogging the dustproof net 37 through the fan 6.

[0048] The working principle of the utility model is as follows: the surface temperature of the electromagnetic encoder body 2 is absorbed by the heat sink 31, and the temperature of the electromagnetic encoder body 2 is absorbed by the heat sink 31, and then the temperature of the heat sink 31 is transferred to the cooling box 33 through the heat conducting plate 32, so that the heat sink 31 can dissipate heat, so that the heat sink 31 can continuously dissipate heat to the electromagnetic encoder body 2, thereby improving the heat dissipation effect, and the heat on the electromagnetic encoder body 2 is conducted and dissipated through the fan 6 to ensure a good heat dissipation environment, and the fan 6 can be taken out by opening the box door 51 for easy maintenance and replacement to ensure heat dissipation efficiency, and the slider 43 is pulled to move the connecting rod 45 fixedly connected to the slider 43, so that the clamping block 46 fixedly connected to the connecting rod 45 moves, and the spring 44 is in a compressed state at this time, thereby facilitating the disassembly of the encoder body 2, and the cover plate 34 can be opened to replenish the coolant in the cooling box 33 to ensure that the coolant is sufficient and provide the best heat dissipation and cooling effect.
