Description

Technical Field

[0001] This utility model belongs to the field of reflective encoder technology, and in particular relates to an ultra-thin split-type reflective encoder. Background Technology

[0002] Split-type reflective encoders are a commonly used position and speed detection device, widely used in many fields such as industrial automation, robotics, and CNC machine tools. Their working principle is to emit light onto a reflective surface with an coded pattern and then receive the reflected light to obtain position or speed information.

[0003] A Chinese patent application with publication number 202120026020.1 discloses an ultra-thin split-type reflective encoder, including an encoder body. The encoder body has a heat insulation cylinder with one open end on its outer side. A heat insulation plate is fixedly connected to the open end of the heat insulation cylinder. A water storage cylinder is sleeved on the outer side of the heat insulation cylinder. The water storage cylinder is fixedly connected to the heat insulation plate by screws. This utility model places the encoder body in the space formed by the heat insulation cylinder and the heat insulation plate, thereby playing a role in heat insulation and preventing heat from the high temperature environment from being directly transferred to the encoder body.

[0004] Although the aforementioned patent can achieve the purpose of water evaporation insulation and reduce the impact of heat on the encoder body, it still has the disadvantage of being large in size. It uses screw mechanical locking to connect the various components. Although this connection method can ensure a certain mechanical strength, it has obvious drawbacks. Since each connection part needs to reserve a certain installation space and dimensional tolerance, the size accumulation problem is serious after multiple components are connected, resulting in a large size of the entire encoder. For example, in some precision instruments, small automated equipment, and special scenarios such as aerospace and medical devices with strict installation space requirements, the aforementioned patent cannot meet the installation requirements due to its large size.

[0005] To address these issues, we provide an ultra-thin split-type reflective encoder. Utility Model Content

[0006] The purpose of this invention is to provide an ultra-thin split-type reflective encoder. By combining the housing, mounting head, and mounting components, it solves the problem that the existing split-type reflective encoders use screw mechanical locking to connect various components, which leads to the accumulation of reflective encoder size and a large overall size.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to an ultra-thin split-type reflective encoder, comprising a housing, a pad fixedly connected to one side of the inner cavity of the housing, a circuit board disposed on one side of the pad, a mounting head disposed on one side of the housing, a mounting assembly disposed between the housing and the mounting head, a rotating shaft disposed on the surface of the mounting head, a code disk fixedly connected to one side of the surface of the rotating shaft, and a mounting rod comprising a mounting rod, one end of the mounting rod being fixedly connected to the surface of the pad, and the other end of the mounting rod being fixedly connected to a threaded cylinder, a threaded head being threadedly connected to the inner cavity of the threaded cylinder, and a rotating rod being fixedly connected to one end of the threaded head.

[0009] The present invention is further configured such that a sealing groove is provided on one side of the outer shell, and a sealing ring is movably connected to the inner cavity of the sealing groove. One side of the sealing ring is fixedly connected to the surface of the mounting head. The sealing ring is inserted into the inner cavity of the sealing groove as the mounting head is installed together with the outer shell. The sealing structure composed of the sealing groove and the sealing ring can improve the connection sealing between the outer shell and the mounting head.

[0010] The present invention is further configured such that a disassembly disc is fixedly connected to one end of the rotating rod, and a paddle is fixedly connected to one side of the disassembly disc. The disassembly disc is rotated by pinching the paddle with a finger, thereby driving the rotating rod on one side of the disassembly disc to rotate.

[0011] The present invention is further configured such that an installation cylinder is fixedly connected to one side of the outer shell, and a rear end cover is threadedly connected to the inner cavity of the installation cylinder. After the rear end cover is screwed into the inner cavity of the installation cylinder, not only can the tail of the outer shell be sealed, but the wires on the circuit board can also be passed through.

[0012] The present invention is further configured such that a wire-passing hole is provided on the surface of the rear end cover, and a protective ring is provided in the inner cavity of the wire-passing hole. The wires on the circuit board can pass through the wire-passing hole on the rear end cover, and the protective ring in the inner cavity of the wire-passing hole can protect the surface of the wires and prevent the surface of the wires from being worn.

[0013] The present invention is further configured such that an annular groove is provided on one side of the threaded cylinder, a limiting disk is fixedly connected to the surface of the threaded head, and an annular pad is fixedly connected to one side of the limiting disk. The annular pad on one side of the limiting disk is engaged in the annular groove as the threaded head is screwed into the inner cavity of the threaded cylinder. The limiting structure composed of the annular groove and the annular pad can improve the connection stability between the threaded cylinder and the threaded head.

[0014] The present invention is further configured such that a sealing cylinder is fixedly connected to one edge of the outer shell, the inner wall of the sealing cylinder is in contact with the surface of the mounting head, and as the mounting head is connected to the outer shell, one side of the mounting head will be inserted into the inner cavity of the sealing cylinder. The sealing cylinder wrapping around the surface of the mounting head can improve the installation stability of the mounting cylinder.

[0015] The present invention is further configured such that a support pad is fixedly connected to one side of the pad, and one side of the support pad is in contact with the surface of the circuit board. As the circuit board is installed on one side of the pad, the support pad is in contact with the surface of the circuit board, and the flexible support pad can protect the surface of the circuit board.

[0016] The present invention has the following beneficial effects.

[0017] 1. This utility model effectively solves the problem of the large size of existing split-type reflective encoders. It replaces the traditional mechanical locking with screws by using a circuit board with a mounting rod, a rear end cover screwed into a mounting cylinder, and a mounting head rotating rod with a threaded head screwed into a threaded cylinder. This significantly reduces the installation space and dimensional tolerance allowance required for each connection part. This design significantly reduces the cumulative size effect after connecting multiple parts, resulting in a significant reduction in the overall size of the encoder. It can adapt to special scenarios with demanding installation space requirements, such as precision instruments, small automated equipment, aerospace, and medical devices.

[0018] 2. The installation process of this utility model is more convenient and efficient. The components are connected by means of fitting, screwing, and thread engagement, eliminating the need for cumbersome screw locking operations. The mounting head and the outer shell can be tightly fitted by rotating the rotating rod, which simplifies the assembly steps and enables the rapid assembly of the components.

[0026] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0027] Please see Figure 1-5 This utility model is an ultra-thin split-type reflective encoder, including a housing 1. A pad 2 is fixedly connected to one side of the inner cavity of the housing 1. A circuit board 3 is provided on one side of the pad 2. A mounting head 4 is provided on one side of the housing 1. A mounting assembly 5 is provided between the housing 1 and the mounting head 4. A rotating shaft 6 is provided on the surface of the mounting head 4. A code disk 7 is fixedly connected to one side of the surface of the rotating shaft 6. The mounting assembly 5 includes a mounting rod 501. One end of the mounting rod 501 is fixedly connected to the surface of the pad 2. A threaded cylinder 502 is fixedly connected to the other end of the mounting rod 501. A threaded head 503 is threadedly connected to the inner cavity of the threaded cylinder 502. A rotating rod 504 is fixedly connected to one end of the threaded head 503.

[0028] Specifically: Move the mounting head 4 until the threaded head 503 at one end of the rotating rod 504 on its surface is inserted into the opening of the threaded cylinder 502. Rotate the rotating rod 504, which drives the threaded head 503 to rotate. As the threaded head 503 rotates, it will slowly screw into the inner cavity of the threaded cylinder 502, thereby driving the mounting head 4 to slowly approach the outer shell 1 until it is tightly fitted with the outer shell 1, thus quickly installing the mounting head 4 and the outer shell 1 together. Example

[0029] Please see Figure 1-5 Based on Embodiment 1, a sealing groove is provided on one side of the outer shell 1, and a sealing ring is movably connected to the inner cavity of the sealing groove. One side of the sealing ring is fixedly connected to the surface of the mounting head 4. A disassembly disc 8 is fixedly connected to one end of the rotating rod 504, and a paddle is fixedly connected to one side of the disassembly disc 8. An mounting cylinder 9 is fixedly connected to one side of the outer shell 1. A rear end cover 10 is threadedly connected to the inner cavity of the mounting cylinder 9. A wire hole is provided on the surface of the rear end cover 10, and a protective ring is provided in the inner cavity of the wire hole. An annular groove is provided on one side of the threaded cylinder 502. A limiting disc is fixedly connected to the surface of the threaded head 503, and an annular pad is fixedly connected to one side of the limiting disc. A sealing cylinder is fixedly connected to the edge of one side of the outer shell 1. The inner wall of the sealing cylinder is in contact with the surface of the mounting head 4. A support pad is fixedly connected to one side of the pad 2, and one side of the support pad is in contact with the surface of the circuit board 3.

[0030] Specifically: The sealing ring is inserted into the inner cavity of the sealing groove as the mounting head 4 is installed together with the outer shell 1. The sealing structure formed by the sealing groove and the sealing ring improves the sealing performance between the outer shell 1 and the mounting head 4. By pinching the lever with your fingers and rotating the disassembly disc 8, the rotating rod 504 on one side of the disassembly disc 8 is rotated. After the rear end cover 10 is screwed into the inner cavity of the mounting cylinder 9, not only is the tail of the outer shell 1 sealed, but the wires on the circuit board 3 can also pass through. The wires on the circuit board 3 can pass through the wire hole on the rear end cover 10, and the protective ring inside the wire hole can protect the surface of the wires to prevent... The surface of the wire is worn. The annular pad on one side of the limiting plate is locked into the annular groove as the threaded head 503 is screwed into the inner cavity of the threaded cylinder 502. The limiting structure composed of the annular groove and the annular pad can improve the connection stability between the threaded cylinder 502 and the threaded head 503. As the mounting head 4 is connected to the outer shell 1, one side of the mounting head 4 will be inserted into the inner cavity of the sealing cylinder. The sealing cylinder wraps around the surface of the mounting head 4, which can improve the installation stability of the mounting cylinder 9. As the circuit board 3 is installed on one side of the pad 2, the support pad contacts the surface of the circuit board 3. The flexible material support pad can protect the surface of the circuit board 3.

[0031] The working principle of this utility model is as follows: First, the circuit board 3 is placed on the surface of the mounting rod 501 until the circuit board 3 contacts the pad 2. After the connecting wire on the circuit board 3 passes through the wire hole on the surface of the rear end cover 10, the rear end cover 10 is screwed into the inner cavity of the mounting cylinder 9. Then, the mounting head 4 is moved until the threaded head 503 at one end of the rotating rod 504 is inserted into the opening of the threaded cylinder 502. The rotating rod 504 is rotated, and the rotating rod 504 drives the threaded head 503 to rotate. As the threaded head 503 rotates, it will slowly screw into the inner cavity of the threaded cylinder 502, thereby driving the mounting head 4 to slowly approach the outer shell 1 until it is tightly attached to the outer shell 1, so as to quickly install the mounting head 4 and the outer shell 1 together.
