In conjunction with Figures 1-3, an automatic film winding device for an amblyopia therapeutic instrument is provided, comprising a shell 1 with an internal cavity, a film box 2 arranged in the internal cavity, a first driving mechanism 3 connected to the film box 2, and a control switch 4 arranged outside the shell 1 and electrically connected to the first driving mechanism 3, the shell 1 has a transparent window 11, a hollow area is provided on the side of the film box 2 facing the transparent window 11, a lighting unit is also provided in the film box 2 with the light irradiation direction facing the hollow area, a film assembly 21 is provided in the film box 2 facing the hollow area, the first driving mechanism 3 is connected to the film assembly 21, the control switch 4 is used to control the driving action of the first driving mechanism 3, and the first driving mechanism 3 is used to drive the film assembly 21 to switch the film facing the hollow area.

In this solution, when amblyopia treatment is needed, the user only needs to place the eyes in front of the transparent window 11. Since the film assembly 21 is directly opposite to the hollow area of the film box 2, the user can observe the film image of the film box 2 through the transparent window 11 to achieve auxiliary treatment of amblyopia. When the film image needs to be switched, the user only needs to turn on the control switch 4 so that the first drive mechanism 3 drives the film assembly 21 to switch the film in front of the hollow area, so that the user can observe another film image. The amblyopia treatment device of this solution does not require the user to manually adjust the switching knob when switching films, which is more labor-saving and more convenient to operate.

Furthermore, the film assembly 21 includes two rotating rollers that are spaced apart and rotatably connected to the film box 2 and a film wound around the two rotating rollers. The first driving mechanism 3 is connected to the rotating rollers by transmission, and the portion of the film between the two rotating rollers is located at one side of the film box 2 and covers the hollow area. The two ends of the film are respectively wound around the two rotating rollers, and the film portion between the two rotating rollers is located at the front side of the film box 2 and covers the hollow area. Therefore, when the first driving mechanism 3 drives the rotating rollers to rotate, the film can be switched in front of the hollow area, so that the image observed by the transparent window 11 is changed.

Furthermore, a transmission assembly 22 is provided at the same end of the two rotating rollers, and the output end of the first driving mechanism 3 is connected to the transmission assembly 22. The first driving mechanism 3 drives the two rotating rollers to rotate simultaneously through the transmission assembly 22. The power of the first driving mechanism 3 can be transmitted to the rotating rollers through the transmission assembly 22, and the two rotating rollers can be driven to rotate clockwise or counterclockwise at the same time, so that the film can be switched without causing the film to be pulled, and the reliability is better.

Furthermore, the transmission assembly 22 includes end gears at the ends of the two rotating rollers, a driving gear connected to the output end of the first driving mechanism 3, and a transmission gear connected between the driving gear and the end gears. Specifically, the end gears, the driving gears, and the transmission gears are symmetrically arranged with each other, the two end gears have the same structure, and the two transmission gears have the same structure. Therefore, when the driving gear rotates, the two end gears can be driven to rotate in the same direction at the same speed, and the two rotating rollers can reliably drive the film switching, and the service life is longer. In some embodiments, the transmission assembly 22 can also be a belt and corresponding pulleys at the ends of the rotating rollers and the output end of the driving mechanism. In some embodiments, the transmission assembly 22 can also be a gear set or a pulley set with other settings, as long as the rotating rollers can rotate in the same direction at the same speed.

Furthermore, the film roll has a plurality of films connected in sequence, a position sensing part may be provided between two adjacent films, a position sensor is provided on one side of the film box 2, and when the positions of the position sensing part and the position sensor correspond, a film is facing the hollow area; after the control switch 4 controls the first driving mechanism 3 to perform a driving action, the first driving mechanism 3 stops the current driving action when the position sensor senses the next position sensing part.

Specifically, the position sensing part can be set as a notch, and the position sensor can be set as a photoelectric sensor. In this way, when the notch is aligned with the photoelectric sensor, the light change triggers the photoelectric sensor. Therefore, after the first drive mechanism 3 is controlled by the control switch 4 to perform the driving action, the first drive mechanism 3 stops the current driving action when the position sensor senses the next position sensing part. In this way, each time the control switch 4 is triggered, the film only switches one film image to the left or right, and because the position sensing part and the position sensor are aligned before stopping, the position of each switch can be made more accurate without position offset or error. In some embodiments, the position sensing part can be a thin metal layer set at the corresponding position, and the position sensor can be a capacitive sensor.

Furthermore, the first driving mechanism 3 includes a fixed frame 31 disposed on the top side of the film box 2 and a motor whose main body is fixed to the fixed frame 31. The motor is electrically connected to the control switch 4, and the output end of the motor is connected to the film assembly 21. The first driving mechanism 3 and the film box 2 are fixed as one body. In this embodiment, the output end of the motor is connected to the transmission assembly 22 as described above, specifically a driving gear, so that when the motor rotates, the two rotating rollers can be driven to rotate. Alternatively, in order to reduce the number of position sensing parts and position sensors, in some embodiments, the motor can be a servo motor. Each time the control switch 4 triggers the servo motor, the servo motor rotates a specific number of circles, so that the film assembly 21 only switches one film. In this way, the cost is lower and the film image is switched more accurately.

Furthermore, the automatic film winding device of the amblyopia treatment device also includes a second driving mechanism 5 connected to the film box 2 and the inner wall of the housing 1, the second driving mechanism 5 is used to drive the film box 2 to move in a direction close to or away from the transparent window 11, and the second driving mechanism 5 is electrically connected to the control switch 4; the control switch 4 has at least two control modes, one control mode is used to control the driving action of the first driving mechanism 3, and the other control mode is used to control the driving action of the second driving mechanism 5. The control switch 4 can control the switching of the film or the forward and backward movement of the film box 2 respectively through the two control modes, which can reduce the number of components to be set, and the operation is more convenient and simple. The second driving mechanism 5 can drive the film box 2 to move forward and backward under the adjustment of the control switch 4 to adapt to the observation habits of different users, and it is more convenient to use.

Furthermore, the second driving mechanism 5 includes a mounting plate 51 arranged at the bottom of the internal cavity of the shell 1, a mounting seat 52 slidably assembled on the mounting plate 51, and a moving component 53 installed on the mounting seat 52 to drive the mounting seat 52 to move forward and backward. The film box 2 is fixed to the mounting seat 52.

Specifically, for example, a slide rail is provided on the top side of the mounting plate 51, and the mounting seat 52 is slidably mounted on the slide rail. The extension direction of the slide rail is toward the transparent window 11, so the mounting seat 52 can slide in the direction close to or away from the transparent window 11, and the connection is stable and reliable; the mounting seat 52 is provided with two slide grooves on both sides of the slide rail, and the mounting seat 52 has two sliders slidably mounted in the two slide grooves, respectively. The moving assembly 53 includes a lead screw rotatably connected to the two ends of a slide groove and a lead screw motor installed on the mounting seat 52 for driving the lead screw to rotate. The lead screw and the corresponding slider are connected in a transmission manner, and the slider is provided with a thread matching the lead screw. The lead screw is driven to rotate by the lead screw motor, and then the lead screw drives the slider to move forward and backward in the slide groove, which can further drive the mounting seat 52 to move forward and backward, so that the film box 2 moves forward and backward. Among them, the lead screw motor can be directly connected to the lead screw coaxially, or a worm is provided at the output end of the lead screw motor, and a worm wheel is provided at the outer periphery of the end of the lead screw. When the worm rotates, it drives the worm wheel to drive the lead screw to rotate.

It should be understood that the structure of the second driving mechanism 5 described above is only used as an example and is not used to limit its structure. As long as the second driving mechanism 5 can be controlled by the control switch 4 to drive the film box 2 to slide forward and backward, it is within the protection scope of the present application. For example, in some embodiments, the film box 2 can be mounted on the inner wall of the housing 1 to slide forward and backward, and the second driving mechanism 5 can use an electric cylinder to drive the film box 2 to move forward and backward. Alternatively, the second driving mechanism 5 can be a rack provided on the inner side of the housing 1 and a gear motor fixedly connected to the film box 2. The gear of the gear motor is meshed with the rack, and the extension direction of the rack is consistent with the sliding direction of the film box 2. In this way, when the gear motor drives the gear to rotate, it can also drive the film box 2 to move forward and backward.

Further, the housing 1 includes a base and a top shell, the top shell is buckled and connected to the top of the base, the film box 2 is arranged in the top shell, and the control switch 4 includes a rocker switch arranged on the base, wherein the rocker switch controls the driving action of the first driving mechanism 3 when swinging left and right, and controls the driving action of the second driving mechanism 5 when swinging back and forth.
