Description

Technical Field

[0001] The present application relates to the field of sensor technology, and in particular to an encoder and a rotating device. Background Art

[0002] An encoder is a sensor that can transmit angles, speeds, and number of revolutions in real time. It is usually installed on the rotating shaft of a servo motor or automation equipment to convert the speed and angular displacement of the rotating shaft into electrical signals for closed-loop feedback. With the popularization of industrial intelligence, various types of automation equipment have increasingly higher requirements for the stability, accuracy, and other performance of servo control systems. As an important feedback unit in a servo control system, encoders also have increasingly higher requirements for their installation size, stability, and service life.

[0003] Currently, mainstream encoders are roughly divided into integrated and split types based on their structural form; integrated encoders have their own bearings inside, which provide high installation stability but relatively large dimensions; split encoders have non-contact code disc shaft and housing, small overall dimensions, and long service life.

[0004] However, when assembling the split encoder, it is necessary to first position and install the encoder body on the rotating device, and after the measuring component is fixed at a specific height of the output shaft of the rotating device, the circuit board is fixed on the encoder body. The separate assembly consumes a lot of time, the installation efficiency is slow and the yield rate is low. Utility Model Content

[0005] The invention aims to solve the problems of slow installation efficiency and low yield rate of split encoders in related technologies.

[0006] A first aspect of the present application is to provide an encoder.

[0007] A second aspect of the present application is to provide a rotating device.

[0008] In view of this, according to the first aspect of the present application, an encoder is proposed, comprising: a main body, having a accommodating cavity, a first port, a second port, a first mounting hole, a second mounting hole and a third mounting hole; the first port and the second port are arranged opposite to each other along the axial direction of the main body, and are connected to the outside and the accommodating cavity; the first mounting hole and the second mounting hole extend along the radial direction of the main body, and are connected to the outside and the accommodating cavity; the third mounting hole penetrates the main body along the axial direction; a measuring component is arranged in the accommodating cavity; the measuring component has a positioning hole, a fourth mounting hole and a fifth mounting hole; the positioning hole extends along the axial direction and is connected to the first port, the fourth mounting hole and the fifth mounting hole extend along the radial direction, the fourth mounting hole is connected to the first mounting hole, the fifth mounting hole is connected to the second mounting hole, and the fifth mounting hole is connected to the positioning hole; a circuit board is arranged above the measuring component and is bonded to the main body; a through hole is provided on the circuit board, and the through hole is connected to the third mounting hole; a first locking piece is inserted into the first mounting hole, and can move back and forth along the first mounting hole to extend into or exit the fourth mounting hole.

[0009] In the above technical solution, before the encoder is used, the first locking piece extends into the fourth mounting hole to pre-fix the main body and the measuring component, thereby ensuring that the relative position of the measuring component and the circuit board remains stable, avoiding misalignment during installation, transportation, etc., which may reduce or invalidate the function of the split non-contact encoder, thereby helping to improve the yield and efficiency of the installation of the encoder.

[0010] Compared with the traditional mechanical connection method, the bonding of the circuit board and the main body can simplify the assembly process, reduce assembly time and cost, and fill the tiny gap between the circuit board and the main body to prevent moisture, dust and other contaminants from entering the interior of the main body, thereby protecting the measurement components and increasing their service life. Finally, the bonding connection method can adapt to the connection requirements of various complex shapes and surfaces, making the connection between the circuit board and the main body more flexible and diverse.

[0011] In some technical solutions, optionally, a second locking piece is further included, which is inserted into the second mounting hole and can move back and forth along the second mounting hole to extend into the positioning hole through the fifth mounting hole or exit the fifth mounting hole.

[0012] In this way, during the final installation, it is only necessary to first extend the second locking piece into the positioning hole through the fifth mounting hole, and then withdraw the first locking piece from the fourth mounting hole; thereby enabling the fixed position of the measuring component of the encoder to be accurately positioned, which helps to improve the yield and efficiency of the installation.

[0013] In some technical solutions, optionally, the first mounting hole is a threaded hole, and the first locking piece is threadedly connected to the first mounting hole; and / or, the fifth mounting hole is a threaded hole, and the second locking piece is threadedly connected to the fifth mounting hole.

[0014] In some technical schemes, optionally, the aperture of the fourth mounting hole is smaller than the aperture of the first mounting hole; wherein, the first locking member includes a first connecting segment and a second connecting segment, the first connecting segment is assembled in the first mounting hole, the second connecting segment is assembled in the fourth mounting hole, and the outer diameter of the first connecting segment is larger than the aperture of the fourth mounting hole.

[0015] In the above technical solution, by setting the outer diameter of the first connecting section to be larger than the hole diameter of the fourth mounting hole, a limiting portion can be formed at the connecting position of the first connecting section and the second connecting section to prevent the first connecting section from extending into the fourth mounting hole, thereby limiting the length of the first locking piece extending into the fourth mounting hole, thereby avoiding the first locking piece extending too deeply during installation and affecting the measuring component, thereby ensuring that the relative position of the measuring component and the circuit board remains stable.

[0016] In some technical solutions, the fourth mounting hole is optionally a through hole. With such a design, during processing, there is no need to consider whether the hole will be drilled too deep, thereby facilitating processing.

[0017] In some technical solutions, optionally, the measuring component includes: a grating, which is arranged in the accommodating cavity; and a rotating shaft, which is connected to the grating; wherein the positioning hole, the fourth mounting hole and the fifth mounting hole are all located on the rotating shaft.

[0018] In some technical solutions, optionally, a light source assembly is further included, and the light source assembly is arranged in the accommodating cavity. The light source assembly can provide a stable light source to ensure the normal operation of the circuit board and the grating.

[0019] In some technical solutions, optionally, the light source assembly includes: a fixing frame, which is arranged in the accommodating cavity and is detachably connected to the main body; and an LED lamp, which is arranged on the fixing frame.

[0020] In some technical solutions, a third locking piece is optionally included, which is inserted into the third mounting hole through the through hole and can move back and forth along the third mounting hole. In this way, during normal installation, the third locking piece can be quickly connected to the device under test, thereby helping to improve installation efficiency.

[0021] According to the second aspect of the present application, the present application proposes a rotating device, comprising: a rotating body, a rotating shaft, and an encoder as proposed in any of the above technical solutions; wherein the rotating shaft is arranged on the rotating body and extends into the positioning hole through the first port. Therefore, the rotating device has all the beneficial effects of any of the above technical solutions, which will not be repeated here.

[0039] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0041] Combine the following Figures 1 to 5 , the encoder and rotating device provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0042] Reference Figure 1 and Figure 4 In an embodiment of the present application, an encoder 10 is provided, the structure of which includes a main body 100, a measuring component 110, a circuit board 120 and a first locking member 130.

[0043] Reference Figure 1 , Figure 2 and Figure 4 Specifically, the main body 100 has a receiving cavity 101, a first port 102, a second port 103, a first mounting hole 104, a second mounting hole 105 and a third mounting hole 106. The first port 102 and the second port 103 are arranged along the axial direction of the main body 100 (eg Figure 2 The first mounting hole 104 and the second mounting hole 105 are arranged opposite to each other and communicate with the outside and the accommodating cavity 101. The first mounting hole 104 and the second mounting hole 105 are arranged along the radial direction of the main body (as shown in FIG. Figure 2 The third mounting hole 106 extends from the main body 100 to the outside and communicates with the accommodating cavity 101. The third mounting hole 106 penetrates the main body 100 in the axial direction.

[0044] The measuring assembly 110 is disposed in the accommodating cavity 101, and includes a positioning hole 111, a fourth mounting hole 112, and a fifth mounting hole 113; the positioning hole 111 extends in the axial direction and is in communication with the first port 102. The fourth mounting hole 112 and the fifth mounting hole 113 extend in the radial direction, wherein the fourth mounting hole 112 is in communication with the first mounting hole 104, the fifth mounting hole 113 is in communication with the second mounting hole 105, and the fifth mounting hole 113 is in communication with the positioning hole 111.

[0045] The circuit board 120 is disposed above the measuring component 110 and bonded to the main body 100 ; a through hole 121 is provided on the circuit board 120 , and the through hole 121 is communicated with the third mounting hole 106 .

[0046] The first locking member 130 is inserted into the first mounting hole 104 and can move back and forth along the first mounting hole 104 to extend into or exit from the fourth mounting hole 112 .

[0047] In the above embodiment, before the encoder 10 is used, the first locking member 130 extends into the fourth mounting hole 112, so that the main body 100 and the measuring component 110 are pre-fixed, thereby ensuring that the relative position of the measuring component 110 and the circuit board 120 remains stable, avoiding the reduction or failure of the function of the encoder 10 due to misalignment during installation, transportation, etc., thereby helping to improve the installation yield and efficiency of the encoder 10.

[0048] The circuit board 120 and the main body 100 are bonded. Compared with the traditional mechanical connection method (such as screws, rivets, etc.), bonding can simplify the assembly process, reduce assembly time and cost, and fill the small gap between the circuit board 120 and the main body 100 to prevent moisture, dust and other pollutants from entering the main body 100, thereby protecting the measuring component 110 and improving the service life; finally, the bonding connection method can adapt to the connection requirements of various complex shapes and surfaces, making the connection between the circuit board 120 and the main body 100 more flexible and diverse. Exemplarily, the circuit board 120 is bonded to the main body 100 by fixing glue. It can be understood that in practical applications, other types of adhesives can also be used, and this embodiment is not limited to this.

[0049] The circuit board 120 is provided with a through hole 121, which is connected to the third mounting hole 106 on the main body 100. In this way, when the encoder 10 is used, the encoder 10 can be connected to the device under test by passing the connecting piece through the through hole 121 and inserting it into the third mounting hole 106. This design can not only improve the installation efficiency, but also provide additional support and fixation between the circuit board 120 and the main body 100, so that the connection between the circuit board 120 and the main body 100 is more stable.

[0050] In some embodiments, the encoder 10 further includes a second locking member 140. The second locking member 140 is inserted into the second mounting hole 105 and can move back and forth along the second mounting hole 105 to extend into the positioning hole 111 through the fifth mounting hole 113 or exit the fifth mounting hole 113.

[0051] In this way, during the final installation, it is only necessary to first extend the second locking member 140 into the positioning hole 111 through the fifth mounting hole 113, and then withdraw the first locking member 130 from the fourth mounting hole 112; thereby, the fixed position of the measuring component 110 of the encoder 10 can be accurately positioned, which helps to improve the yield rate and efficiency of the installation.

[0052] In the above embodiment, the first mounting hole 104 is a threaded hole, and the first locking member 130 is threadedly connected to the first mounting hole 104. The fifth mounting hole 113 is a threaded hole, and the second locking member 140 is threadedly connected to the fifth mounting hole 113. The threaded connection has a simple installation process, helps to improve the installation efficiency, and can also provide a more secure fixing effect to ensure the stability of the encoder during use.

[0053] Specifically, the first fastening member 130 and the second fastening member 140 are screws, but it is understandable that they can also be other connection structures that can achieve a fastening effect, such as rivets, pins, and buckles, and the present embodiment is not limited thereto.

[0054] In practical applications, the second mounting hole 105 and the fourth mounting hole 112 are light holes. In this embodiment, the second mounting hole 105 is designed to be a different type from the first mounting hole 104, so that it is convenient for users to quickly identify and install the corresponding first locking member 130 and second locking member 140, which helps to improve installation efficiency, and the processing of the light hole is simpler.

[0055] Reference Figure 4 and Figure 5 In some embodiments, the diameter of the fourth mounting hole 112 is smaller than the diameter of the first mounting hole 104. Specifically, the first locking member 130 includes a first connecting segment 131 and a second connecting segment 132, the first connecting segment 131 is assembled in the first mounting hole 104, the second connecting segment 132 is assembled in the fourth mounting hole 112, and the outer diameter of the first connecting segment 131 is larger than the diameter of the fourth mounting hole 112.

[0056] In the above embodiment, by setting the outer diameter of the first connecting section 131 to be larger than the hole diameter of the fourth mounting hole 112, a limiting portion can be formed at the connecting position of the first connecting section 131 and the second connecting section 132 to prevent the first connecting section 131 from extending into the fourth mounting hole 112, so that the length of the first locking member 130 extending into the fourth mounting hole 112 is limited, thereby preventing the first locking member 130 from extending too deeply during installation and affecting the measuring component 110, thereby ensuring that the relative position of the measuring component 110 and the circuit board 120 remains stable.

[0057] In some embodiments, the fourth mounting hole 112 is a through hole, that is, it passes through the measuring assembly 110. With this design, during processing, there is no need to consider whether the hole will be drilled too deep, thereby facilitating processing.

[0058] In some embodiments, in order to achieve a stable connection, there are multiple first mounting holes 104 and second mounting holes 105, which are arranged at intervals along the circumferential direction. Correspondingly, there are multiple fourth mounting holes 112 and fifth mounting holes 113. In this embodiment, the number of first mounting holes 104 is 3, and the number of second mounting holes 105 is 2.

[0059] Reference Figure 2 and Figure 4 In some embodiments, the measuring assembly 110 includes a grating 114 and a rotating shaft 115. The grating 114 is disposed in the accommodating cavity 101 and is opposite to the circuit board 120. The rotating shaft 115 is connected to the grating 114. Specifically, the positioning hole 111, the fourth mounting hole 112, and the fifth mounting hole 113 are located on the rotating shaft 115.

[0060] Reference Figure 3 and Figure 4 In the above embodiment, the encoder 10 further includes a light source assembly 150. The light source assembly 150 is disposed in the accommodating cavity 101 to provide a stable light source to ensure the normal operation of the circuit board 120 and the grating 114.

[0061] Specifically, the light source assembly 150 includes a fixing frame 151 and an LED lamp 152. Specifically, the fixing frame 151 is disposed in the accommodating cavity 101 and is detachably connected to the main body 100; the LED lamp 152 is disposed on the fixing frame 151.

[0062] In practical applications, the fixing frame 151 and the main body 100 can be connected by screws 153. It is understandable that in practical applications, the detachable connection can also be achieved by bonding and snapping, and the present embodiment is not limited thereto.

[0063] In some embodiments, the encoder 10 further includes a third fastening member 160. The third fastening member 160 is inserted into the third mounting hole 106 through the through hole 121 and can move back and forth along the third mounting hole 106. In this way, during normal installation, the third fastening member 160 can be quickly connected to the device under test, thereby helping to improve installation efficiency. In this embodiment, the third fastening member 160 is a screw, but it can be understood that the third fastening member 160 can also be other connection structures that can achieve a fastening effect, such as rivets, pins, and buckles, and this embodiment is not limited thereto.

[0064] Reference Figure 5 In some embodiments, the present application further provides a rotating device 20, comprising a rotating body 200, a rotating shaft 210, and an encoder 10 provided in any of the above embodiments. Specifically, the rotating shaft 210 is disposed on the rotating body 200 and extends into the positioning hole 111 through the first port 102. Thus, the rotating device 20 has all the beneficial effects of any of the above embodiments, which will not be described in detail.

[0065] In some embodiments, the rotating body 200 is provided with a fixing hole 220 adapted to communicate with the third mounting hole 106. In this way, the encoder 10 can be fixed by passing the third locking member 160 through the through hole 121 and the third mounting hole 106 into the fixing hole 220.

[0066] Reference Figure 5 , the specific installation steps are as follows:

[0067] (1) The rotating shaft 210 is inserted into the positioning hole 111 through the first port 102 to fit the main body 100 and the rotating body 200;

[0068] (2) The third locking member 160 passes through the through hole 121 and the third mounting hole 106 and extends into the fixing hole 220 to fix the encoder 10 as a whole;

[0069] (3) The second locking member 140 extends into the positioning hole 111 through the fifth mounting hole 113 and contacts and locks the rotating shaft 210, thereby fixing the measuring assembly 110 and the rotating shaft 210 relatively;

[0070] (4) The first locking member 130 is withdrawn from the fourth mounting hole 112 or directly removed, so that the main body 100 and the measuring component 110 are unfixed and realize a non-contact state.
