Description

Technical Field

[0001] This utility model belongs to the field of photoelectric encoder technology, specifically, it relates to a connection device for a photoelectric encoder. Background Technology

[0002] An optical encoder is a sensor that can convert mechanical motion into digital signal output. It typically consists of a grating and a photodetector. When an object moves along the grating, the photodetector detects the change in light signal on the grating and converts it into a digital pulse signal output, thereby realizing the measurement and control of the motion state.

[0003] A search revealed that existing methods for connecting photoelectric encoders and PLC instruments require connecting the wiring via electrical wiring (with the wiring hinged together and wrapped with insulating material or fixed to the interface with bolts). This method is cumbersome and inconvenient for installing and removing photoelectric encoders and PLC instruments, increasing the time required for installation and removal.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To solve the technical problem of line connection, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A connection device for an optical encoder includes an optical encoder body with wiring fixedly connected to its end; a quick-connect assembly connected to the wiring at the end of the optical encoder body, the quick-connect assembly being used for quick loading and unloading of the optical encoder body and a PLC instrument, the quick-connect assembly including a connecting end, a snap-fit ​​end, and connecting blocks, the connecting end being fixedly connected to the wiring at the end of the optical encoder body, the snap-fit ​​end snapping into the connecting end, and connecting blocks being elastically connected inside both the connecting end and the snap-fit ​​end, with the connecting blocks abutting against each other.

[0007] In a preferred embodiment of the present invention, a movable block is elastically connected to the connecting end, and an array of abutting blocks are arranged on the connecting end, with each abutting block abutting against the movable block. A groove is provided on the snap-fit ​​end, and the abutting block abuts against the groove.

[0008] In a preferred embodiment of this utility model, a cavity is provided between the movable block and the connecting end, and a second spring is provided in the cavity. One end of the second spring is fixedly connected to the connecting end, and the other end of the second spring is fixedly connected to the movable block.

[0009] In a preferred embodiment of this utility model, the inner wall of the movable block is provided with a sliding groove, each abutting block is in contact with the sliding groove, each abutting block is slidably connected to the connecting end, and the end of the connecting end is engaged with a limit ring, and the movable block abuts against the limit ring.

[0010] In a preferred embodiment of the present invention, a fixing block is fixedly connected inside the snap-fit ​​end, a connecting block is slidably connected on the fixing block, a first spring is sleeved on the connecting block, one end of the first spring is fixedly connected to the connecting block, and the other end of the first spring is fixedly connected to the fixing block.

[0011] In a preferred embodiment of this utility model, the end of the connecting block is tapered, and a buffer ring is snapped into the end of the connecting block. The buffer ring abuts against the inner wall of the snap-in end, and the connecting end is equipped with the same structure as the snap-in end.

[0012] In a preferred embodiment of this utility model, the connecting end is provided with a plurality of grooves, and a straightening ring is fixedly installed in the grooves, the straightening ring abutting against the outer wall of the snap-fit ​​end.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This is a connection device for a photoelectric encoder. The movable block is manually pushed towards the photoelectric encoder body, and the snap-fit ​​end is inserted into the appropriate position in the connection end. Through the cooperation of the components in the quick-connect assembly, the snap-fit ​​end and the connection end are fixed. The movable block is manually pushed, and the components in the quick-connect assembly quickly separate from the snap-fit ​​end, thus quickly completing the installation and removal of the connection end and the snap-fit ​​end. This reduces the number of operation steps, reduces the operation time, and improves the portability of the photoelectric encoder body connection device.

[0015] 2. In this photoelectric encoder connection device, when the snap-fit ​​end and the connection end snap-fit ​​together, the connecting blocks are subjected to a pushing force. The connecting blocks compress the first spring, and the first spring deforms after being compressed, applying the deformation force to the connecting blocks. The connecting blocks are pushed by the first spring, and the connecting blocks in the connection end and the snap-fit ​​end are pushed to abut against each other, avoiding the connection block at one end being too long, which would prevent the connection end and the snap-fit ​​end from snapping together, thus improving the applicability of the device. At the same time, the first spring ensures that the connecting blocks are in close contact, avoiding loose connections.

[0016] 3. In this photoelectric encoder connection device, when the connection end and the snap-fit ​​end are separated, the connection block is pushed by the first spring. The connection block first contacts the inner wall of the connection end and the snap-fit ​​end through the buffer ring at the end, buffering the impact force and avoiding damage to the optical fiber at the end of the connection block by the force generated by the impact.

[0017] 4. In this photoelectric encoder connection device, a limiting ring at the end of the connection end limits the movable block to prevent it from slipping off the connection end. When the internal components of the connection end are damaged, the limiting ring can be removed, the movable block loses its restriction, and can be removed from the connection end, making it convenient to repair and replace the movable block, the abutment block, and the second spring.

[0018] 5. In this photoelectric encoder connection device, after the snap-fit ​​end snaps into the connection end, the outer wall of the snap-fit ​​end contacts multiple straightening rings inside the connection end. The straightening rings restrict the position of the snap-fit ​​end, keeping it in the middle of the connection end, ensuring that the connection blocks can align and avoiding misalignment that could lead to poor contact.

[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] Please see Figure 1-5A connection device for an optical encoder includes an optical encoder body 1, with wiring fixedly connected to the end of the optical encoder body 1; a quick-connect assembly, which is connected to the wiring at the end of the optical encoder body 1. The quick-connect assembly is used for quickly assembling and disassembling the optical encoder body 1 and a PLC instrument. The quick-connect assembly includes a connecting end 2, a snap-fit ​​end 3, and a connecting block 31. The connecting end 2 is fixedly connected to the wiring at the end of the optical encoder body 1, and the snap-fit ​​end 3 snaps into the connecting end 2. Both the connecting end 2 and the snap-fit ​​end 3 are elastically connected to the connecting block 31, which abut against each other. When a movable block 4 is manually pushed toward the optical encoder body 1, the snap-fit ​​end 3 is inserted into the appropriate position in the connecting end 2. Through the cooperation of the components within the quick-connect assembly, the snap-fit ​​end 3 and the connecting end 2 are fixed. When the movable block 4 is manually pushed, the components within the quick-connect assembly quickly separate from the snap-fit ​​end 3, quickly completing the assembly and disassembly of the connecting end 2 and the snap-fit ​​end 3, reducing operation steps, reducing operation time, and improving the portability of the connection device for the optical encoder body 1.

[0029] The connecting end 2 is elastically connected to a movable block 4, and an array of abutment blocks 41 are arranged on the connecting end 2, with each abutment block 41 abutting against the movable block 4. A groove is provided on the locking end 3, and the abutment blocks 41 abut against the groove. A chamber is provided between the movable block 4 and the connecting end 2, and a second spring 42 is provided within the chamber. One end of the second spring 42 is fixedly connected to the connecting end 2, and the other end of the second spring 42 is fixedly connected to the movable block 4. A sliding groove is provided on the inner wall of the movable block 4, and each abutment block 41 contacts the sliding groove. Each abutment block 41 is slidably connected to the connecting end 2. A limit ring 43 is locked at the end of the connecting end 2, and the movable block 4 abuts against the limit ring 43. When the movable block 4 is manually pushed towards the photoelectric encoder body 1, the locking end 3 is moved... When the connecting end 2 is positioned appropriately, the locking end 3 pushes the abutment block 41 into the groove of the movable block 4, releasing the movable block 4. During the movement of the movable block 4, it compresses the second spring 42. The second spring 42 deforms after being compressed and applies the deformation force to the movable block 4. The movable block 4 is pushed by the second spring 42 towards the locking end 3, pushing the abutment block 41 back into the connecting end 2 and abutting against the groove on the locking end 3. The limiting ring 43 at the end of the connecting end 2 limits the movable block 4 to prevent it from slipping off the connecting end 2. When the internal components of the connecting end 2 are damaged, the limiting ring 43 is removed, and the movable block 4 is no longer restricted and can be removed from the connecting end 2, making it convenient to repair and replace the movable block 4, the abutment block 41, and the second spring 42.

[0030] The snap-fit ​​end 3 has a fixed block 32 fixedly connected inside, and a connecting block 31 slidably connected to the fixed block 32. A first spring 33 is sleeved on the connecting block 31. One end of the first spring 33 is fixedly connected to the connecting block 31, and the other end of the first spring 33 is fixedly connected to the fixed block 32. The end of the connecting block 31 is tapered, and a buffer ring 34 is snapped onto the end of the connecting block 31. The buffer ring 34 abuts against the inner wall of the snap-fit ​​end 3. The connecting end 2 has the same structure as the snap-fit ​​end 3. When the snap-fit ​​end 3 and the connecting end 2 are snapped together, the connecting blocks 31 are subjected to a pushing force. The connecting block 31 compresses the first spring 33, and the first spring 33 deforms after being compressed. The deformation force is applied to the connecting block 31, which is pushed by the first spring 33. The connecting block 31 in the connecting end 2 and the snap-fit ​​end 3 are pushed to abut against each other, so as to avoid the connecting block 31 at one end being too long, which would prevent the connecting end 2 and the snap-fit ​​end 3 from being unable to snap together, thus improving the applicability of the device. At the same time, the connecting blocks 31 are in close contact through the first spring 33 to avoid loose connection. When the connecting end 2 and the snap-fit ​​end 3 are separated, the connecting block 31 is pushed by the first spring 33. The connecting block 31 first contacts the inner wall of the connecting end 2 and the snap-fit ​​end 3 through the buffer ring 34 at the end, which buffers the impact force and prevents the optical fiber at the end of the connecting block 31 from being damaged by the impact force.

[0031] The connecting end 2 has multiple grooves, and a straightening ring 44 is fixedly installed in each groove. The straightening ring 44 abuts against the outer wall of the snap-fit ​​end 3. After the snap-fit ​​end 3 snaps into the connecting end 2, the outer wall of the snap-fit ​​end 3 contacts the multiple straightening rings 44 in the connecting end 2. The straightening rings 44 restrict the position of the snap-fit ​​end 3, keeping the snap-fit ​​end 3 in the middle of the connecting end 2, ensuring that the connecting blocks 31 can be connected and avoiding misalignment that could lead to poor contact.

[0032] Working principle: The movable block 4 is manually pushed towards the photoelectric encoder body 1, and the snap-fit ​​end 3 is inserted into the appropriate position within the connecting end 2. Through the cooperation of components within the quick-connect assembly, the snap-fit ​​end 3 and the connecting end 2 are fixed together. Manually pushing the movable block 4 causes the components within the quick-connect assembly to quickly separate from the snap-fit ​​end 3, rapidly completing the installation and removal of the connecting end 2 and the snap-fit ​​end 3. This reduces operation steps and time, improving the portability of the photoelectric encoder body 1 connection device. The movable block 4 is manually pushed towards the photoelectric encoder body 1, and the snap-fit ​​end 3 is inserted into the appropriate position within the connecting end 2. The snap-fit ​​end 3 then pushes the abutment block 41 towards the movable block 4. The movable block 4 is pushed into the groove, releasing the movable block 4. During its movement, the movable block 4 compresses the second spring 42. The second spring 42 deforms under pressure, applying the force of this deformation to the movable block 4. The movable block 4 is pushed by the second spring 42 towards the locking end 3, pushing the abutment block 41 back into the connecting end 2 and abutting against the groove on the locking end 3. The limiting ring 43 at the end of the connecting end 2 limits the movable block 4, preventing it from slipping off the connecting end 2. If the internal components of the connecting end 2 are damaged, the limiting ring 43 can be removed, freeing the movable block 4 from its restraint and allowing it to be removed from the connecting end 2 for easy removal. The components such as the abutting block 41 and the second spring 42 are repaired or replaced. When the locking end 3 and the connecting end 2 are engaged, the connecting blocks 31 are subjected to a pushing force, and the connecting blocks 31 compress the first spring 33. The first spring 33 deforms after being compressed and applies the deformation force to the connecting blocks 31. The connecting blocks 31 are pushed by the first spring 33, and the connecting blocks 31 in the connecting end 2 and the locking end 3 are pushed to abut against each other, so as to avoid the connecting block 31 at one end being too long, which would prevent the connecting end 2 and the locking end 3 from being unable to engage, thus improving the application range of the device. At the same time, the first spring 33 ensures that the connecting blocks 31 are in close contact, avoiding To prevent poor connection, when the connecting end 2 and the snap-fit ​​end 3 are separated, the connecting block 31 is pushed by the first spring 33. The connecting block 31 first contacts the inner wall of the connecting end 2 and the snap-fit ​​end 3 through the buffer ring 34 at the end, which buffers the impact force and prevents the optical fiber at the end of the connecting block 31 from being damaged by the impact force. After the snap-fit ​​end 3 snaps into the connecting end 2, the outer wall of the snap-fit ​​end 3 contacts the multiple straightening rings 44 in the connecting end 2. The straightening rings 44 restrict the position of the snap-fit ​​end 3 and keep the snap-fit ​​end 3 in the middle of the connecting end 2, ensuring that the connecting blocks 31 can be connected and avoiding misalignment that leads to poor contact.
