Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and in particular to a manual unwinding device for small animal signal cables. Background Technology

[0002] In neuroscience and behavioral research, experimental animals are usually equipped with devices such as signal acquisition devices, stimulators, or miniature microscopes, which are connected to data acquisition systems via cables to monitor or intervene in physiological data in real time. However, when animals move freely, the cables are prone to tangling, leading to signal interruption, data loss, or restricted animal behavior, which in turn affects the accuracy of the experiment.

[0003] Current unwinding technologies mainly include automated devices and passive solutions. Automated unwinding uses electronic components and motors to achieve active unwinding, which is highly efficient but expensive and complex in structure. Passive solutions rely on the inherent characteristics of the cable to unwind, which is low in cost but has limited effectiveness.

[0004] Automatic unwinding technology uses sensors and controllers to drive a motor to unwind. Although it is highly efficient, it relies on a complex signal detection mechanism and is prone to continuous incorrect unwinding direction due to sensor misjudgment, which may even exacerbate the entanglement and cause experimental accidents.

[0005] Therefore, this utility model provides a simple and efficient unwinding device. Utility Model Content

[0006] To address the problem of incorrect cable unwinding direction caused by sensor misjudgment, this invention proposes a manual unwinding device for small animal signal cables.

[0022] The purpose, features, and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0023] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0024] Please refer to Figure 1 This utility model proposes a manual unwinding device for a small animal signal cable 16, comprising a camera device and an unwinding device, wherein:

[0025] The camera device includes a camera 3 for observing the unwinding state. The unwinding device includes a drive mechanism, a slip ring 9, and a signal converter 15. The bottom of the signal converter 15 is connected to a cable 16 that needs to be unwinded. The drive mechanism drives the slip ring 9 to rotate and drives the signal converter 15 to rotate, so that the connected cable 16 is unwinded. The drive mechanism is connected to an adjustable pulse generator 6 through a first transmission line 7. The adjustable pulse generator 6 is used to adjust the speed of the drive mechanism.

[0026] In a specific embodiment, cable 16 is a multi-channel flexible cable 16, with one end fixed to the animal head device and the other end connected to the signal converter 15. The adjustable pulse generator adjusts the pulse frequency through the potentiometer and outputs it to the drive mechanism, thereby realizing adjustable control of the unwinding speed. The camera 3 can monitor cable 16 in real time and determine the winding direction of cable 16. After knowing the winding direction of cable 16, the drive mechanism is used to drive the slip ring 9 to rotate, thereby completing the unwinding of cable 16 connected to the bottom of the signal converter 15. This utility model provides intuitive visual feedback to the experimenter by monitoring the winding state of cable 16 in real time through camera 3, and then uses the drive mechanism to drive the slip ring 9 to rotate and unwind cable 16. This can eliminate the risk of continuous erroneous unwinding due to sensor misjudgment and improve the safety and stability of the experiment.

[0027] Furthermore, it also includes a display 1, which is connected to a camera 3 via a second transmission line 2.

[0028] In a specific implementation, the display 1 is used to display the real-time captured image of the camera 3, and the camera 3 is used to monitor the real-time status of the cable 16 that needs to be unspinned, so as to facilitate subsequent unspinning.

[0029] Furthermore, the drive mechanism includes a housing 19 and a stepper motor 8 fixed inside the housing 19. A control chip 10 is also provided inside the housing 19, and the control chip 10 is electrically connected to the stepper motor 8.

[0030] In a specific implementation, the housing 19 is used to house the drive mechanism, the stepper motor 8 is used to provide the power source, and the control chip 10 is an Arduino microcontroller chip 10. The control chip 10 has a built-in program that reads the status of the direction control switch and the emergency stop switch 5, and outputs signals to the stepper motor 8 through digital pins.

[0031] Furthermore, the drive mechanism also includes a first gear 11 and a second gear 12. The first gear 11 is connected to the output end of the stepper motor 8, and the second gear 12 meshes with the first gear 11.

[0032] In a specific embodiment, the gear ratio of the first gear 11 and the second gear 12 is 1:2, the second gear 12 is larger than the first gear 11, the first gear 11 is connected to the output terminal of the stepper motor 8, and the stepper motor 8 drives the first gear 11 to rotate, which in turn drives the second gear 12 to rotate.

[0033] Furthermore, the drive mechanism also includes a mating part 13 and a suspension arm 17. One end of the mating part 13 passes through the housing 19 and is fixedly connected to the second gear 12, and the other end is connected to the suspension arm 17. The bottom of the suspension arm 17 is connected to the signal converter 15.

[0034] In a specific embodiment, the mating part 13 connects the suspension arm 17 and the second gear 12. When the second gear 12 rotates, it will drive the suspension arm 17 to rotate through the mating part 13, which will further drive the signal converter 15 on the suspension arm 17 to move and rotate, thereby unwinding the cable 16.

[0035] Furthermore, the slip ring 9 is fixedly connected to the second gear 12, and the slip ring 9 is connected to the signal converter 15 through the third transmission line 14.

[0036] In a specific implementation, the slip ring 9 is a 24-channel slip ring 9. The slip ring 9 is fixed on the second gear 12 and rotates synchronously with the second gear 12. The slip ring 9 is connected to the signal converter 15 through the third transmission line 14. By unspinning the slip ring 9, the experimental animal is connected to the signal converter 15, and signals can be transmitted in real time.

[0037] Furthermore, a bearing 18 is also provided inside the box body 19. The outer side of the bearing 18 is fixedly connected to the box body 19, and the inner side of the bearing 18 is fixedly connected to the mating part 13.

[0038] In a specific embodiment, the inner side of the bearing 18 is nested on the outer side of the mating part 13, and the outer side of the bearing 18 is fixed to the housing 19 by bolts to reduce the friction between the mating part 13 and the housing 19.

[0039] Furthermore, the adjustable pulse generator 6 is equipped with a direction control key 4 and an emergency stop switch 5. The direction control key 4 is used to control the rotation direction of the stepper motor 8, and the emergency stop switch 5 is used to control the stop of the stepper motor 8.

[0040] In a specific implementation, after confirming the winding direction of the cable 16, the direction control switch is used to select whether the stepper motor 8 rotates clockwise or counterclockwise, thereby unwinding the cable 16. In case of an abnormal situation, pressing the emergency stop switch 5 can immediately stop the action of the stepper motor 8. Using the direction control key 4 and the emergency stop switch 5, the rotation direction and start / stop of the stepper motor 8 can be directly controlled, ensuring the flexibility and reliability of the unwinding operation. By adjusting the pulse frequency, the speed of the stepper motor 8 can also be controlled to adapt to different unwinding speeds, providing better flexibility.

[0041] In summary, during actual use, the experimenter observes the state of the cable 16 captured by the camera 3 through the display 1, determines the winding direction, and then uses the direction control switch to select whether to control the stepper motor 8 to rotate counterclockwise or clockwise. At the same time, the adjustable pulse generator 6 is adjusted to set the rotation speed of the stepper motor 8. Subsequently, the control chip 10 receives the command and drives the stepper motor 8 to rotate. The torque is transmitted through the first gear 11 and the second gear 12, and finally the power is transmitted to the slip ring 9, thereby rotating and unwinding the tangled cable 16.

[0042] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
