Description

Technical Field

[0001] This utility model relates to the field of photoelectric turntable technology, and in particular to a photoelectric turntable. Background Technology

[0002] The photoelectric turntable includes a detection chamber, a base, and two rotating shafts. The detection chamber achieves pitch rotation on the base via one rotating shaft and horizontal rotation on the base via the other rotating shaft. The rotation of the rotating shafts is controlled by drive motors. During the operation of the photoelectric turntable, the drive motors controlling the rotation of the rotating shafts need to be connected to an external power source to allow for adjustment and locking of the rotation angle of the rotating shafts.

[0003] However, when the photoelectric turntable is not in operation, such as during storage, transportation, handling, or hoisting, the aforementioned drive motor cannot be connected to an external power source, and the rotating shaft may not even be connected to the drive motor. Therefore, the rotation angle of the shaft cannot be locked. Consequently, during these operations, the detection chamber can easily rotate arbitrarily on the base, increasing the difficulty of the operation and even creating safety hazards. Utility Model Content

[0004] Therefore, it is necessary to provide an optoelectronic turntable to address the problem that the detection chamber can easily rotate on the base when the optoelectronic turntable is not in operation.

[0005] A photoelectric turntable, comprising:

[0006] Base;

[0007] A rotating shaft is rotatably mounted on the base, and a locking hole is provided on the side wall of the rotating shaft;

[0008] A first annular component is fixed on the base. A locking rod and an elastic element are provided on the first annular component. The locking rod is movably arranged along the radial direction of the first annular component. The two ends of the elastic element abut against the first annular component and the locking rod, respectively.

[0009] A second annular member is rotatably disposed on the base, wherein one of the first annular member and the second annular member is arranged around the outside of the other, and the second annular member has a locking surface, and the locking rod points toward the locking surface;

[0010] A locking motor, which is mounted on the base and is used to drive the second annular member to rotate on the base;

[0011] A built-in power supply is mounted on the base and electrically connected to the locking motor;

[0012] The photoelectric turntable has a locked state and an unlocked state;

[0013] When the photoelectric turntable is in the locked state, the distance between the portion of the first annular member at the locking rod and the locking surface on the axis of the locking rod is d1, and the locking surface abuts against one end of the locking rod so that the other end of the locking rod is located in the locking hole;

[0014] When the photoelectric turntable is in the unlocked state, the distance between the portion of the first annular member at the locking rod and the locking surface on the axis of the locking rod is d2, where d2 > d1, and the locking rod is located outside the locking hole.

[0015] In some embodiments, one of the first annular member and the second annular member is provided with at least two limit switches, and the other is provided with a trigger, wherein the limit switches are electrically connected to the locking motor;

[0016] The two limit switches are a first limit switch and a second limit switch; when the photoelectric turntable is in the locked state, the trigger contacts the first limit switch; when the photoelectric turntable is in the unlocked state, the trigger contacts the second limit switch.

[0017] In some embodiments, the pivot is located in the middle of the first annular member, the second annular member is arranged around the outside of the first annular member, and the locking surface is located at the inner edge of the second annular member.

[0018] In some embodiments, the second annular member further has a limiting surface located at the inner edge of the second annular member and abutting against the outer edge of the first annular member, so that the second annular member is positioned radially in relation to the first annular member.

[0019] In some embodiments, a gear is provided on the motor shaft of the locking motor, and a transmission tooth is provided on the outer edge of the second annular member, the gear meshing with the transmission tooth.

[0020] In some embodiments, a first limiting ring is provided on the outer edge of the first annular member, and the second annular member is supported on the first limiting ring.

[0021] In some embodiments, a first slip-enhancing washer is provided between the second annular member and the first limiting ring.

[0022] In some embodiments, the photoelectric turntable further includes a pressure ring, which is fixed to the first annular member and spaced apart from the first limiting ring, and the second annular member is clamped between the first limiting ring and the pressure ring.

[0023] In some embodiments, a second slip-enhancing washer is provided between the pressure ring and the second annular member.

[0024] In some embodiments, the photoelectric turntable further includes a detection chamber, and the rotating shaft is driven to the detection chamber.

[0025] In some embodiments, the locking surface is an arc surface.

[0026] The beneficial effects of this utility model are as follows:

[0027] In the photoelectric turntable of this utility model, when the rotating shaft loses the lock of the drive motor, the built-in power supply can supply power to the locking motor, and then the locking motor controls the second ring to rotate on the base, thereby using the locking surface in conjunction with the elastic element to control the movement of the locking rod on the first ring.

[0028] Specifically, when the photoelectric turntable is in the locked state, the distance between the part of the first annular member at the locking rod and the locking surface on the locking rod axis is d1. Since d1 is small, the locking surface can abut against one end of the locking rod and cause the elastic member to deform to a large degree, thereby causing the other end of the locking rod to move toward the rotating shaft, and finally causing the end of the locking rod to be inserted into the locking hole.

[0029] When the photoelectric turntable is in the locked state, the locking motor, powered by its built-in power supply, can stably lock the second annular component, thus preventing any change in the contact position between the locking surface and the end of the locking rod. The end of the locking rod can be stably inserted into the locking hole, ensuring that the locking rod can restrict the rotation of the shaft on the base. Therefore, when the photoelectric turntable is not in operation, both the operational difficulty and safety hazards are reduced.

[0030] When the photoelectric turntable is in the unlocked state, the distance between the portion of the first annular component at the locking rod and the locking surface on the locking rod axis is d2, where d2 > d1, meaning d2 is relatively large. Therefore, the degree of pushing of the locking surface against the locking rod is low, or even the locking surface and the locking rod are spaced apart. Consequently, the deformation of the elastic component is small or even non-deformable. Thus, the distance between the locking rod and the rotating shaft is large, allowing the locking rod to be located outside the locking hole. The rotating shaft loses the restraining effect of the locking rod. At this point, as long as the rotating shaft is connected to the drive motor and the drive motor is connected to an external power source, the rotating shaft can rotate normally under the control of the drive motor.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0051] Example 1:

[0052] like Figure 1 and Figure 2 As shown, this embodiment provides a photoelectric turntable, including a base 1, a rotating shaft 2, and a detection chamber 7. The rotating shaft 2 is rotatably mounted on the base 1, and the rotating shaft 2 transmits power to the detection chamber 7, thereby allowing the detection chamber 7 to rotate on the base 1.

[0053] In this system, the rotation of the photoelectric turntable's rotating shaft 2 is controlled by a drive motor connected to an external power source, allowing for adjustment and locking of the rotation angle of the shaft 2. In other words, the rotation of the shaft 2 and the detection chamber 7 on the base 1 is controlled during operation of the photoelectric turntable.

[0054] There is a one-to-one correspondence between the rotating shaft 2 and the drive motor. In some embodiments, there is one rotating shaft 2, in which case the rotating shaft 2 can make the probe chamber 7 pitch or rotate horizontally on the base 1. In other embodiments, there are two rotating shafts 2, with the probe chamber 7 mounted on one rotating shaft 2 and the corresponding drive motor mounted on the other rotating shaft 2. In this case, the two rotating shafts 2 respectively make the probe chamber 7 pitch and rotate horizontally on the base 1.

[0055] When the photoelectric turntable is not in operation, such as during operations like storage, transportation, handling, and hoisting, the rotating shaft 2 is usually not connected to the drive motor. Even if it is connected, the drive motor cannot connect to an external power source and receive power. Therefore, when the photoelectric turntable is not in operation, the rotating shaft 2 cannot be locked on the base 1, causing the detection chamber 7 to rotate freely on the base 1 due to external shaking or vibration. This increases the difficulty and safety hazards of the aforementioned storage, transportation, handling, and hoisting operations.

[0056] To address the aforementioned issues, the photoelectric turntable in this embodiment further includes a first annular component 3, a second annular component 4, a locking motor 5, and a built-in power supply.

[0057] The first annular component 3, the second annular component 4, the locking motor 5, and the built-in power supply are all mounted on the base 1. Therefore, even when the photoelectric turntable is not in operation, the first annular component 3, the second annular component 4, the locking motor 5, and the built-in power supply are still located on the base 1.

[0058] The built-in power source can be a battery or a power supply module mounted on a circuit board.

[0059] In this configuration, one of the first annular member 3 and the second annular member 4 is arranged around the outside of the other. The first annular member 3 is fixed to the base 1, while the second annular member 4 is rotatably arranged on the base 1.

[0060] like Figure 3 , Figures 5-10 As shown, the first annular member 3 is provided with a locking rod 31 and an elastic member 32. The locking rod 31 is movably disposed along the radial direction of the first annular member 3, and the two ends of the elastic member 32 abut against the first annular member 3 and the locking rod 31, respectively.

[0061] For example, a guide hole 35 is provided on the first annular member 3, extending radially along the first annular member 3. The two ends of the guide hole 35 extend to the inner and outer edges of the first annular member 3, respectively. A locking rod 31 passes through the guide hole 35, with its axis coinciding with the axis of the guide hole 35. One end of the guide hole 35 forms a step 351 by reducing its diameter, and the other end of the guide hole 35 is fixed with a limiting cover plate 352. The outer wall of the middle portion of the locking rod 31 forms a second limiting ring 311 by protrusion. The second limiting ring 311 is located between the limiting cover plate 352 and the step 351, thereby limiting the axial movement range of the locking rod 31 and preventing the locking rod 31 from completely disengaging from the guide hole 35. The locking rod 31 and the second limiting ring 311 guide the axial movement of the locking rod 31 by fitting against the side wall of the guide hole 35. The two ends of the elastic element 32 abut against the second limiting ring 311 and the step 351 respectively, wherein the limiting cover plate 352 is provided with a clearance hole for the end of the locking rod 31 to move.

[0062] The locking motor 5 drives the second annular component 4, and the built-in power supply is electrically connected to the locking motor 5. When the photoelectric turntable is not in operation, the built-in power supply can supply power to the locking motor 5, which drives the second annular component 4 to rotate on the base 1. The locking motor 5 then adjusts and locks the rotation angle of the second annular component 4. In this embodiment, the built-in power supply is specifically a power supply module and is electrically connected to the locking motor 5 via a circuit board.

[0063] Further as Figure 4 As shown, the second annular member 4 has a locking surface 41, one end of the locking rod 31 points towards the locking surface 41, and the other end of the locking rod 31 points towards the rotating shaft 2. In other words, by moving on the first annular member 3, the locking rod 31 can contact the locking surface 41, the rotating shaft 2, or both simultaneously. During the rotation of the second annular member 4, the relative position between the locking surface 41 and the guide hole 35 will continuously change, thereby continuously changing the distance between the ends of the locking surface 41 and the guide hole 35 on the axis of the locking rod 31. Therefore, with the cooperation of the elastic member 32, the axial movement of the locking rod 31 can be controlled by the rotation of the second annular member 4.

[0064] Specifically in this embodiment, the rotating shaft 2 is located in the middle of the first annular member 3, and the second annular member 4 is arranged around the outside of the first annular member 3. Correspondingly, the locking surface 41 is located at the inner edge of the second annular member 4 so as to allow the locking surface 41 to abut against the end of the locking rod 31.

[0065] A locking hole 21 is provided on the side wall of the rotating shaft 2, and the photoelectric turntable has a locked state and an unlocked state.

[0066] specific Figure 3 , Figure 8 and Figure 9As shown, when the photoelectric turntable is in the locked state, the distance between the portion of the first annular member 3 at the locking rod 31 and the locking surface 41 on the axis of the locking rod 31 (in this embodiment, this distance is the distance between the end of the guide hole 35 at the outer edge of the first annular member 3 and the locking surface 41 on the axis of the locking rod 31) is d1. Since d1 is small, the locking surface 41 can abut against one end of the locking rod 31 and cause the second limiting ring 311 to press against the elastic member 32, thereby causing the other end of the locking rod 31 to move toward the rotating shaft 2, and finally causing the end of the locking rod 31 to be inserted into the locking hole 21. When the photoelectric turntable is in the locked state, the locking motor 5 can stably lock the second annular member 4 by means of power provided by the built-in power supply, thereby preventing the contact position between the locking surface 41 and the end of the locking rod 31 from changing, so that the locking rod 31 can be stably inserted into the locking hole 21, ensuring that the locking rod 31 can restrict the rotation of the rotating shaft 2 on the base 1. Therefore, when the photoelectric turntable is not in operation, the difficulty of operation and safety hazards can be reduced.

[0067] like Figure 6 and Figure 7 As shown, when the photoelectric turntable is in the unlocked state, the distance between the portion of the first annular member 3 at the locking rod 31 and the locking surface 41 on the axis of the locking rod 31 is d2, where d2 > d1, i.e., d2 is relatively large. Therefore, the degree of pushing of the locking surface 41 against the locking rod 31 is low, or even the locking surface 41 and the locking rod 31 are spaced apart. Correspondingly, the deformation of the elastic member 32 is small or even non-deformable, resulting in a larger distance between the locking rod 31 and the rotating shaft 2, with the locking rod 31 located outside the locking hole 21. When the photoelectric turntable is in the unlocked state, the rotating shaft 2 loses the restraining effect of the locking rod 31. At this time, as long as the rotating shaft 2 is connected to the drive motor, and the drive motor is connected to an external power source, the rotating shaft 2 can rotate normally under the control of the drive motor.

[0068] When the drive motor is connected to an external power source, it can send a signal to the circuit board, which in turn controls the second annular component 4 to rotate by the locking motor 5. This gradually increases the distance between the portion of the first annular component 3 at the locking rod 31 and the locking surface 41 on the axis of the locking rod 31. Under the reset action of the elastic component 32, the end of the locking rod 31 gradually leaves the locking hole 21, and the photoelectric turntable switches from the locked state to the unlocked state.

[0069] Before the drive motor is disconnected from the external power supply, the drive motor will control the rotating shaft 2 to reset and rotate, so that the locking hole 21 can be aligned with the end of the locking rod 31. At the same time, the drive motor will send a signal to the circuit board, and then the locking motor 5 will control the second ring 4 to rotate and move the locking rod 31 toward the rotating shaft 2. Finally, the photoelectric turntable switches from the unlocked state to the locked state.

[0070] Alternatively, after the circuit board detects that the drive motor is disconnected from the external power supply, it will control the second annular component 4 to rotate via the locking motor 5 until the end of the locking rod 31 abuts against the outer wall of the rotating shaft 2. At this time, although the locking motor 5 is still outputting torque to the second annular component 4, the locking rod 31 cannot move further toward the axis of the rotating shaft 2 due to the obstruction of the outer wall of the rotating shaft 2. Therefore, the further rotation of the second annular component 4 is hindered. However, on the other hand, since the rotating shaft 2 has lost the lock of the drive motor, it can now rotate freely on the base 1. The user can manually rotate the rotating shaft 2. Once the end of the locking rod 31 is aligned with the locking hole 21, the second annular component 4 will lose the obstruction of the outer wall of the rotating shaft 2 and rotate further. The end of the locking rod 31 will automatically enter the locking hole 21, thereby completing the switch from the unlocked state to the locked state.

[0071] In this embodiment, during the switching between the unlocked and locked states of the photoelectric turntable, the end of the locking rod 31 slides on the locking surface 41. To reduce resistance during the switching process, the locking surface 41 is preferably an arc surface in this embodiment.

[0072] like Figures 10-12 As shown, preferably, in this embodiment, one of the first annular member 3 and the second annular member 4 is provided with at least two limit switches 33, and the other is provided with a trigger member 42. The limit switches 33 are electrically connected to the locking motor 5, and the two limit switches 33 are respectively the first limit switch 331 and the second limit switch 332.

[0073] When the photoelectric turntable is in the locked state, the trigger 42 contacts the first limit switch 331, and the first limit switch 331 sends a signal to the locking motor 5 to indicate that the second ring 4 has rotated into place. At this time, the locking surface 41 has pushed the locking rod 31 a sufficient distance, and the end of the locking rod 31 has fully entered the locking hole 21. The locking motor 5 completes the locking of the second ring 4.

[0074] When the photoelectric turntable is in the unlocked state, the trigger 42 contacts the second limit switch 332, and the second limit switch 332 sends a signal to the locking motor 5 to indicate that the second ring 4 has rotated into place. At this time, the locking surface 41 and the end of the guide hole 35 have sufficient distance on the axis of the locking rod 31. Under the action of the elastic member 32, the end of the locking rod 31 has disengaged from the locking hole 21, and the locking motor 5 completes the unlocking of the second ring 4.

[0075] In some other embodiments, the limit switch 33 and the trigger 42 may also be replaced by an angular displacement encoder.

[0076] Preferably, the two ends of the locking rod 31 in this embodiment are spherical. This can reduce the resistance when the end of the locking rod 31 slides on the locking surface 41, and also facilitate the entry of the end of the locking rod 31 into the locking hole 21.

[0077] Preferably, in this embodiment, the opening size of the locking hole 21 is slightly larger than the end size of the locking rod 31, so as to facilitate the entry of the end of the locking rod 31 into the locking hole 21.

[0078] like Figure 4 As shown, in this embodiment, the second annular member 4 also has a limiting surface 43, which is located at the inner edge of the second annular member 4. Further as... Figure 5 , Figures 10-12 As shown, the limiting surface 43 is in contact with the outer edge of the first annular member 3, thereby enabling the second annular member 4 to be positioned radially in the first annular member 3.

[0079] Based on this, in order to enable the locking motor 5 to drive to the second annular member 4, a transmission tooth 44 is provided on the outer edge of the second annular member 4, and a gear 51 is provided on the motor shaft of the locking motor 5, which meshes with the transmission tooth 44.

[0080] Preferably, in this embodiment, a first limiting ring 34 is also provided on the outer edge of the first annular member 3, and the second annular member 4 can be supported on the first limiting ring 34 to prevent the second annular member 4 from separating from the first annular member 3 during rotation.

[0081] In a further preferred embodiment, the photoelectric turntable also includes a pressure ring 6, which is fixed to the first annular member 3 and spaced apart from the first limiting ring 34. The second annular member 4 is sandwiched between the first limiting ring 34 and the pressure ring 6. The first limiting ring 34 and the pressure ring 6 cooperate to axially limit the second annular member 4.

[0082] In this embodiment, a first slip-enhancing washer 341 is provided between the second annular member 4 and the first limiting ring 34, and a second slip-enhancing washer 61 is provided between the pressure ring 6 and the second annular member 4. The first slip-enhancing washer 341 and the second slip-enhancing washer 61 can be made of POM (polyoxymethylene). The first slip-enhancing washer 341 and the second slip-enhancing washer 61 can reduce the resistance when the second annular member 4 rotates.

[0083] Example 2:

[0084] The difference between this embodiment and embodiment 1 is that the rotating shaft 2 is located outside the first annular member 3, the first annular member 3 is arranged around the outside of the second annular member 4, the locking surface 41 and the limiting surface 43 are located on the outer edge of the second annular member 4, and the limiting surface 43 and the inner edge of the first annular member 3 are in contact, so that the second annular member 4 is radially positioned.

[0085] In this embodiment, the distance between the portion of the first annular member 3 at the locking rod 31 and the locking surface 41 on the axis of the locking rod 31 is the distance between the end of the guide hole 35 at the inner edge of the first annular member 3 and the locking surface 41 on the axis of the locking rod 31.

[0086] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0087] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
