[0002] Rotary encoders are important sensors widely used in industrial automation, automotive electronics, aerospace, and other fields. By combining optical, mechanical, and electronic technologies, rotary encoders achieve high-precision rotational motion measurement. They convert mechanical rotational motion into electrical signals for measuring parameters such as angle, speed, and position.

[0003] Traditional split-type rotary encoders typically consist of a grating assembly and a mounting base. During the assembly of a split-type rotary encoder onto a motor, to avoid contamination of the grating assembly, tweezers are usually used to pick it up and place it into the motor's mounting base. Then, a height positioning fixture is used to position the code disk height, and finally, the grating fixing screws are tightened. However, this process makes it difficult to ensure the installation height of the grating assembly, and the grating assembly is easily contaminated, which seriously affects the installation efficiency of the grating assembly.

[0010] In one embodiment, the mounting base has a mounting slot facing away from the motor, the mounting slot being used to accommodate and limit the grating assembly.

[0011] In one embodiment, the bottom of the mounting base is provided with a clearance hole for the motor shaft to pass through, so that the shaft can be rotatably positioned within the mounting groove.

[0012] In one embodiment, one of the first mating part and the second mating part is a latching protrusion, and the other of the first mating part and the second mating part is a latching recess, wherein the latching protrusion and the latching recess are detachably connected.

[0028] This utility model proposes an encoder mounting fixture 100.

[0029] Please see Figures 1 to 4In one embodiment of this utility model, the encoder mounting fixture 100 includes a fixed base 1 and a transfer assembly 2. The fixed base 1 is used to connect the motor 5 and has a first mating part 11. The transfer assembly 2 includes a driving member 21 and a moving member 22. The driving member 21 can drive the moving member 22 to transfer the grating assembly 3. The moving member 22 has a second mating part 221, which is located on the side of the moving member 22 facing the fixed base 1. The second mating part 221 can be connected with the first mating part 11. When the first mating part 11 is connected with the second mating part 221, the moving member 22 can move the grating assembly 3 to the rotating shaft 51 of the motor 5 and fix the height of the grating assembly 3.

[0030] This utility model provides an encoder mounting fixture 100, which includes a fixed base 1 and a transfer assembly 2. The fixed base 1 is used to connect with a motor 5 and includes a first mating part 11, which can be a positioning hole 22b, a positioning groove, or other positioning structure. The transfer assembly 2 includes a driving member 21 and a moving member 22. The driving member 21 can be a cylinder, an electric push rod, or other driving device to provide power to drive the moving member 22. The moving member 22 is provided with a second mating part 221, which is located on the side of the moving member 22 facing the fixed base 1. The second mating part 221 can be a positioning pin, a positioning block, or other structure that can be connected to the first mating part 11. When the first mating part 11 is connected to the second mating part 221, the moving member 22 can accurately move the grating assembly 3 to a predetermined position on the motor 5 shaft 51 and fix the height of the grating assembly 3. The precise connection between the first mating part 11 and the second mating part 221 ensures that the grating assembly 3 can be accurately installed at the predetermined position on the rotating shaft 51 of the motor 5, avoiding errors caused by manual operation in traditional assembly processes. The design of the transfer component 2 avoids direct hand contact with the grating assembly 3, reducing contamination caused by human operation and improving the optical performance and reliability of the grating assembly 3. By using the driving component 21 to drive the moving component 22, the grating assembly 3 can be moved quickly and accurately, reducing assembly steps and improving installation efficiency.

[0031] In one embodiment of this utility model, please refer to Figure 4 The driving component 21 is a negative pressure device 211, and the moving component 22 has an airflow channel 22a, which is connected to the negative pressure device 211.

[0032] In this embodiment, the driving component 21 employs a negative pressure device 211 to achieve contactless handling and precise positioning of the grating assembly 3. Specifically, the moving component 22 has an airflow channel 22a inside, one end of which is connected to the negative pressure device 211, and the other end extends to the end of the moving component 22, forming a negative pressure adsorption surface. During installation, the negative pressure device 211 is activated, generating negative pressure on the adsorption surface through the airflow channel 22a, thereby firmly adsorbing the grating assembly 3. Subsequently, driven by the driving mechanism, the moving component 22 moves along a preset trajectory, precisely transferring the grating assembly 3 to the installation position of the motor 5 shaft 51. When the grating assembly 3 reaches the designated position, the negative pressure device 211 stops working, releasing the grating assembly 3 and completing the installation. The entire process requires no manual contact with the grating assembly 3, avoiding the contamination and inaccurate positioning problems that may be caused by tools such as tweezers in traditional assembly. By using the negative pressure device 211 as the driving component 21 and setting the airflow channel 22a in the moving component 22, contactless handling and precise positioning of the grating assembly 3 are achieved. This design not only avoids surface contamination of the grating assembly 3 caused by manual operation or tool contact, significantly improving the optical performance and installation accuracy of the grating assembly 3, but also ensures the stability of the grating assembly 3 during the transfer process through the stability of negative pressure adsorption, reducing the risk of damage caused by vibration or accidental collision.

[0033] In one embodiment of this utility model, please refer to Figure 4 The movable part 22 has a positioning hole 22b, which is located at one end of the movable part 22 near the fixed base 1. The positioning hole 22b is used to position the grating assembly 3.

[0034] In one embodiment, the movable component 22 has a positioning hole 22b at one end near the fixed base 1 for precise positioning of the grating assembly 3. Specifically, the shape and size of the positioning hole 22b match the outer contour of the grating assembly 3; for example, it can be designed as a circle, square, or other hole adapted to the shape of the grating assembly 3. During installation, after the grating assembly 3 is attracted by the negative pressure device 211, it moves through the airflow channel 22a to the positioning hole 22b of the movable component 22. The outer contour of the grating assembly 3 fits tightly with the positioning hole 22b, thereby achieving precise positioning and fixation of the grating assembly 3 during movement. When the movable component 22 moves the grating assembly 3 to the installation position of the motor 5 shaft 51, the positioning hole 22b ensures the coaxiality and height accuracy of the grating assembly 3 and the motor 5 shaft 51, providing stable support for subsequent fixing operations.

[0035] In one embodiment of this utility model, please refer to Figure 4 The movable part 22 has a movable boss 222 protruding at one end near the fixed base 1, and the channel opening of the airflow channel 22a is located on the side of the movable boss 222 facing the fixed base 1.

[0036] In this embodiment, a movable boss 222 is provided at the end of the movable component 22 near the fixed base 1. This movable boss 222 is used to optimize the layout and function of the airflow channel 22a. Specifically, the channel opening of the airflow channel 22a is located on the side of the movable boss 222 facing the fixed base 1, so that the negative pressure generated by the negative pressure device 211 can directly act on the grating assembly 3. During installation, when the movable component 22 approaches the fixed base 1, the channel opening on the movable boss 222 aligns with the corresponding structure on the fixed base 1, forming a stable negative pressure adsorption area. In this way, the grating assembly 3 can be accurately adsorbed and fixed on the movable boss 222, and then smoothly transferred to the installation position of the motor 5 shaft 51 under the action of negative pressure. This design not only improves the handling accuracy of the grating assembly 3, but also enhances its stability during the transfer process, ensuring the smooth progress of the installation process. The design of the movable boss 222 makes the negative pressure adsorption area more concentrated and stable, reducing the problem of insufficient adsorption force caused by airflow dispersion, thereby ensuring that the grating assembly 3 will not be displaced or fall off during the transfer process.

[0037] In one embodiment of this utility model, please refer to Figure 4 The movable component 22 has multiple airflow channels 22a. The opening of each airflow channel 22a is spaced apart from the movable boss 222. The opening of each airflow channel 22a is located on the side of the movable boss 222 facing the fixed base 1.

[0038] In one embodiment, the movable component 22 has a movable boss 222 at one end near the fixed base 1. The movable boss 222 has multiple airflow channels 22a, with the openings of each channel 22a spaced apart on the side of the movable boss 222 facing the fixed base 1. Specifically, these airflow channels 22a are connected to a negative pressure device 211, forming multiple adsorption points on the movable boss 222 through the evenly distributed channel openings. When the negative pressure device 211 is activated, multiple channel openings simultaneously generate negative pressure, enabling more uniform and secure adsorption of the grating assembly 3. During installation, after the grating assembly 3 is adsorbed onto the movable boss 222, the movable component 22 smoothly transfers the grating assembly 3 to the installation position of the motor 5 shaft 51. The arrangement of multiple airflow channels 22a ensures the stability and accuracy of the grating assembly 3 during the transfer process, providing a reliable guarantee for subsequent fixing operations. By providing multiple airflow channels 22a at intervals on the movable boss 222, the encoder mounting fixture 100 of this invention can significantly improve the adsorption stability and installation accuracy of the grating assembly 3. The design of multiple airflow channels 22a makes the negative pressure adsorption force distribution more uniform, effectively avoiding adsorption instability or local stress concentration caused by a single adsorption point, thereby reducing the risk of displacement or damage to the grating assembly 3 during transfer. In addition, the uniformly distributed adsorption points can better adapt to grating assemblies 3 of different shapes and sizes, enhancing the versatility and flexibility of the fixture, and further improving the assembly efficiency and reliability of the encoder.

[0039] In one embodiment of this utility model, please refer to Figure 4 The mounting base 1 has a mounting slot 1a with the slot facing away from the motor 5. The mounting slot 1a is used to accommodate and limit the grating assembly 3.

[0040] In this embodiment, the mounting base 1 has a mounting groove 1a with its opening facing away from the motor 5. The shape and size of the mounting groove 1a match the grating assembly 3, and it is used to accommodate and limit the grating assembly 3 during installation. Specifically, the opening of the mounting groove 1a faces the opposite direction to the motor 5, facilitating the entry of the grating assembly 3 into the groove from the outside of the mounting base 1. When the moving part 22 moves the grating assembly 3 to the vicinity of the mounting base 1, the grating assembly 3 can be accurately aligned and embedded in the mounting groove 1a. The inner wall of the mounting groove 1a limits the grating assembly 3, ensuring its positional accuracy and stability during installation. Subsequently, the grating assembly 3 is fixed to the rotating shaft 51 of the motor 5 by a fixing device, completing the installation. This design makes the positioning of the grating assembly 3 more accurate during installation, reducing installation errors caused by positional deviations. The design of the mounting groove 1a provides a precise positioning space for the grating assembly 3, ensuring that it will not shift or shake during installation, thereby improving the overall installation quality of the encoder.

[0041] In one embodiment of this utility model, please refer to Figure 1 The bottom of the fixed base 1 is provided with a clearance hole 1b, which is used for the rotating shaft 51 of the power supply 5 to pass through, so that the rotating shaft 51 is rotated in the mounting groove 1a.

[0042] In one embodiment, a clearance hole 1b is provided at the bottom of the mounting base 1. The diameter of the clearance hole 1b matches the outer diameter of the motor 5 shaft 51, allowing the motor 5 shaft 51 to pass through the mounting base 1 during installation. Specifically, the central axis of the clearance hole 1b is coaxially aligned with the central axis of the mounting groove 1a, ensuring that the motor 5 shaft 51 can accurately pass through the clearance hole 1b and extend into the mounting groove 1a. When installing the grating assembly 3, after the motor 5 shaft 51 passes through the clearance hole 1b, the grating assembly 3 is fed into the mounting groove 1a by the moving part 22 and coaxially assembled with the motor 5 shaft 51. This design allows the grating assembly 3 to be accurately installed on the motor 5 shaft 51, while the clearance hole 1b provides sufficient space for the shaft 51 to rotate freely during installation and operation, thereby achieving efficient assembly of the encoder and the motor 5. The design of the clearance hole 1b ensures that the motor 5 shaft 51 can be accurately positioned and smoothly pass through the fixed seat 1 during installation, avoiding assembly difficulties caused by interference between the shaft 51 and the fixed seat 1. At the same time, the clearance hole 1b provides sufficient space for the shaft 51 to rotate freely within the mounting slot 1a, ensuring the stability and accuracy of the encoder during operation.

[0043] In one embodiment of this utility model, please refer to Figure 4 One of the first mating part 11 and the second mating part 221 is a locking protrusion, and the other of the first mating part 11 and the second mating part 221 is a locking recess. The locking protrusion and the locking recess are detachably connected.

[0044] In this embodiment, the first mating part 11 of the fixed base 1 and the second mating part 221 of the transfer component 2 adopt a detachable connection method of a convex and a concave engagement. The first mating part 11 is designed as a concave structure located at the end of the fixed base 1 near the moving part 22; while the second mating part 221 is designed as a convex structure that matches the concave engagement, located at the end of the moving part 22 near the fixed base 1. The shapes and sizes of the convex and the concave engagement match each other, enabling rapid positioning and connection. During installation, the moving part 22, driven by the drive component 21, aligns the convex engagement with the concave engagement and inserts it, thus connecting the two. At this time, the moving part 22 can accurately transfer the grating component 3 to the installation position of the motor 5 shaft 51 and maintain stability through the engagement of the convex and the concave engagement. After installation, the convex and the concave engagement can be easily disassembled, facilitating subsequent operations. By adopting a detachable connection method of convex and concave engagement, the encoder installation fixture 100 of this utility model significantly improves assembly efficiency and flexibility. The design of the convex and the concave engagement allows for rapid positioning and connection, reduces alignment time and operational difficulty during assembly, and improves installation accuracy. Meanwhile, the detachable connection method makes the maintenance and replacement of installation tools more convenient, reducing the maintenance cost of the equipment.

[0045] This utility model also proposes a motor 5-component 200, please refer to [link / reference]. Figure 5 The motor 5 assembly 200 includes an encoder mounting fixture 100, an encoder, and a motor 5. The specific structure of the encoder mounting fixture 100 is as described in the above embodiments. Since this motor 5 assembly 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The encoder includes a grating assembly 3 and a PCBA 4; the motor 5 is detachably connected to the mounting base 1, and the motor 5 has a rotating shaft 51, which is detachably connected to the grating assembly 3.

[0046] In one embodiment, the motor 5 assembly 200 integrates the encoder mounting fixture 100, the encoder, and the motor 5 into a single, complete assembly system. Specifically, the motor 5 assembly 200 includes an encoder mounting fixture 100 for precisely mounting the grating assembly 3. The encoder consists of the grating assembly 3 and a PCBA 4. The grating assembly 3 converts mechanical rotation signals into optical signals, while the PCBA 4 processes these signals and outputs electrical signals. The motor 5 is connected to the mounting base 1 via a detachable connection, such as a threaded connection or a snap-fit ​​connection, facilitating installation and maintenance. The motor 5's shaft 51 is also detachably connected to the grating assembly 3, for example, by screws or slots, ensuring the grating assembly 3 is securely mounted on the shaft 51. During assembly, the grating assembly 3 is first precisely positioned and fixed to the motor 5's shaft 51 using the encoder mounting fixture 100. Subsequently, the PCBA 4 connects to the grating assembly 3, completing the encoder installation. This integrated design simplifies the assembly process and improves assembly efficiency and accuracy.

[0047] In one embodiment of this utility model, please refer to Figure 1 The fixing base 1 has a fixing hole 1c, which is located on the side wall of the fixing base 1.

[0048] In this embodiment, a fixing hole 1c is provided on the side wall of the fixing base 1 to achieve a stable connection between the fixing base 1 and the motor 5 or other mounting structures. In specific implementations, the fixing hole 1c can be designed as a threaded hole, a smooth hole, or other suitable structural form according to actual needs. For example, when the fixing base 1 and the motor 5 are connected by a thread, the fixing hole 1c is a threaded hole, and the fixing base 1 can be firmly installed on the housing of the motor 5 using screws or bolts. This design allows the fixing base 1 to accurately position and stably support the grating assembly 3, ensuring its coaxiality and installation accuracy with the motor 5's rotating shaft 51. At the same time, the position and number of fixing holes 1c can be flexibly adjusted according to the size of the motor 5 and installation requirements to meet the needs of different application scenarios.
