DETAILED DESCRIPTION

[0020] An embodiment of the utility model is shown in the figure. In order to achieve the above-mentioned purpose, the utility model provides an eye detection device with an integrated slit lamp, including a base 1, a platform 2 arranged on the base 1, and a slit lamp assembly 3 arranged on the platform 2; the platform 2 is movably connected to the base 1, and a belt 4, a pulley group 5 and a first motor 6 are arranged between the platform 2 and the base 1, the belt 4 is sleeved on the pulley group 5, the belt 4 is connected to the platform 2, and a connecting component is arranged between the belt 4 and the platform 2 for fastening the platform 2 and the belt 4, and the first motor 6 drives the belt 4 to rotate through the pulley group 5 to drive the platform 2 to move.

[0021] When implementing the present scheme, technical personnel in this field will set a slit lamp assembly 3 on the platform 2. The platform 2 in the present scheme can move in coordination with the base 1 to drive the detection device on the platform 2 including the slit lamp assembly 3 to move along the moving direction of the platform 2. The movement of the platform 2 and the base 1 in the present scheme is achieved by setting a belt 4, a pulley group 5 and a first motor 6. The first motor 6 in the present scheme is only a motor for driving the pulley group 5 to rotate. When the motor drives the pulley group 5 to rotate, the belt 4 will also rotate with the pulley group 5. At this time, it is only necessary to set a connecting component between the belt 4 and the platform 2 to fasten the two together, so as to realize the movement of the platform 2 when the belt 4 moves. The connection between the platform 2 and the belt 4 in the present scheme can be a fastening connection method such as bolting, gluing, clamping and positioning the belt 4 on the platform 2, etc. The connection method is simple, easy to operate and does not consume labor.

[0022] The connecting component includes a fixing block 7 arranged on the belt 4 for fixed connection with the platform 2. The fixing block 7 is fixed to the platform 2 by bolts. The belt 4 is placed between the fixing block 7 and the platform 2. The fixing block 7 cooperates with the platform 2 to clamp and fix the belt 4.

[0023] When implementing this solution, a fixing block 7 and bolts are used to clamp the belt 4. A technician in this field can first place the fixing block 7 at a fixed position on the corresponding platform 2, and then position the platform 2 and the fixing block 7 by bolts. At this time, the bolts cannot be fully tightened. The belt 4 needs to be passed between the fixing block 7 and the platform 2 first, and then the fixing block 7 and the bolts are tightened so that the fixing block 7 and the platform 2 can clamp and position the belt 4. The installation method is simple and easy to operate.

[0024] A slider 8 is arranged on the platform 2 at a position corresponding to the slit lamp assembly 3, and an arc guide rail 81, a connecting rod 82 and a second motor 83 are arranged on the slider 8, and a linear guide rail 84 is arranged on the connecting rod 82. The slit lamp assembly 3 passes through the arc guide rail 81 and the linear guide rail 84, one end of the connecting rod 82 is fixedly connected to the second motor 83, and the other end is arranged at a position corresponding to the arc guide rail 81, and swings in an arc trajectory with one end fixed with the connecting rod 82 and the second motor 83 as the center of the circle, and the second motor 83 drives the connecting rod 82 to swing and drives the slit lamp assembly 3 to move along the arc guide rail 81; at least one zero position sensor 38 is arranged on the arc guide rail 81 corresponding to its end position, and the connecting rod 82 can sense the zero position sensor 38, and the inner walls on both sides of the length direction of the arc guide rail 81 are arranged equidistantly.

[0025] When the present scheme is implemented, a slider 8 is provided on the platform 2 at a position corresponding to the slit lamp assembly 3, and an arc guide rail 81, a connecting rod 82 and a second motor 83 are integrated on the slider 8. The inner walls on both sides of the arc guide rail 81 are equidistantly arranged to ensure that the trajectory of the slit lamp assembly 3 is stable during movement and to prevent the slit lamp from escaping from the arc guide rail 81 during movement. In other schemes, if an arc guide rail 81 with unequally arranged inner walls on both sides is used, then the technicians in this field need to adopt other structures that can position the slit lamp assembly 3 in the arc guide rail 81 to meet the detection requirements. One end of the connecting rod 82 is fixedly connected to the second motor 83, and the other end is arranged at a position corresponding to the arc guide rail 81, and the arc guide rail 81 is formed with the fixed end of the motor as the center. The slit lamp assembly 3 swings along an arc trajectory, and passes through the arc guide rail 81 and the linear guide rail 84 on the connecting rod 82 to achieve precise movement in multiple directions; when the position of the slit lamp assembly 3 needs to be adjusted, the second motor 83 is started to drive the connecting rod 82 to swing, thereby driving the slit lamp assembly 3 to move along the arc guide rail 81. At least one zero position sensor 38 is provided at the end of the arc guide rail 81 to sense the position of the connecting rod 82. When the connecting rod 82 swings to the end, the zero position sensor 38 sends a signal to ensure that the slit lamp assembly 3 can pause moving or accurately return to the initial position. By adopting these structures, the slit lamp assembly 3 can achieve fast and precise position adjustment in scenarios such as ophthalmic examinations to meet different inspection requirements.

[0026] A fundus camera 9 is slidably arranged on the platform 2, and a slit lamp assembly 3 is arranged on at least one side corresponding to the fundus camera 9. The fundus camera 9 moves toward or away from the human eye position, and the slit lamp assembly 3 moves in an oblique straight line with the human eye position. The fundus camera 9 and the slit lamp assembly 3 move staggered with each other; there are two slit lamp assemblies 3, which are respectively located on both sides of the fundus camera 9.

[0027] When the present scheme is implemented, a fundus camera 9 is slidingly arranged on the platform 2. The fundus camera 9 can move in a straight line direction on the platform 2, approaching or moving away from the human eye position. A slit lamp assembly 3 is respectively arranged on both sides of the platform 2. The two slit lamp assemblies 3 are respectively located on both sides of the fundus camera 9. The slit lamp assembly 3 moves in an oblique straight line with the human eye position. In the present scheme, the movement trajectory of the fundus camera 9 is a straight line and is close to or away from the human eye position, which is used to adjust the distance between it and the human eye so as to move to the optical imaging working position, and the movement trajectory of the two slit lamp assemblies 3 is an oblique straight line, and the oblique angle thereof can be adjusted according to the actual inspection requirements to ensure that the best lighting angle and position can be provided for the fundus camera 9 during the inspection process, that is, when the fundus camera 9 is detecting the human eye, the fundus camera 9 moves to a position close to the human eye. At this time, the slit lamp assemblies 3 on both sides cannot move toward the position close to the human eye to avoid To prevent the two from meeting, on the contrary, when the slit lamp assembly 3 is detecting the position of the human eye, one of the two slit lamp assemblies 3 approaches the human eye position to detect one of the eyes, and at this time the other slit lamp assembly will not approach the human eye position until the eye being detected completes the detection. The slit lamp assemblies 3 arranged on both sides of the fundus camera 9 in this scheme are one on the left and one on the right, and the slit lamp assembly 3 on the left is set for detecting the left eye of the human body, and the slit lamp assembly 3 on the right is set for detecting the right eye of the human body, and the moving position relationship of the fundus lamp and the slit lamp assembly 3 involved in any of the following schemes or improvements is implemented according to the moving method of the fundus lamp and the slit lamp assembly 3 of this scheme. This design ensures that the fundus camera 9 and the slit lamp assembly 3 do not interfere with each other during the movement, and can flexibly adjust the position to meet the needs of different ophthalmic examinations. Through this structural design, the fundus camera 9 and the slit lamp assembly 3 can achieve coordinated movement to improve the efficiency and accuracy of ophthalmic examinations.

[0028] A fundus camera 9 is slidably arranged on the platform 2, and a slit lamp assembly 3 is arranged on at least one side corresponding to the fundus camera 9. The fundus camera 9 moves in a vertical straight line with the position of the human eye, and the slit lamp assembly 3 moves in an oblique straight line with the position of the human eye. The fundus camera 9 and the slit lamp assembly 3 move in an offset manner.

[0029] When the present scheme is implemented, the moving paths of the slit lamp assembly 3 and the fundus camera 9 are both close to or away from the human eye. The present scheme preferably adopts the method of setting the moving path of the fundus camera 9 to a straight line movement perpendicular to the position of the human eye, while the moving path of the slit lamp assembly 3 is set to an oblique straight line movement. In the present scheme, the two cannot approach the position of the human eye at the same time, and need to be staggered when moving to avoid collision and damage to the equipment. Such a setting can flexibly adjust the position of the detection device and is easy to operate.

[0030] The slit lamp assembly 3 includes an oblique slide 31 and a third motor 3232 for driving the slider 8 to slide. The slider 8 is connected to the oblique slide 31 to drive the arc guide rail 81 to move obliquely towards or away from the human eye. The third motor 3232 is provided with a bevel gear 321, and the slider 8 is provided with a bevel rack 322 for meshing with the bevel gear 321. The third motor 3232 drives the slider 8 to slide to drive the arc guide rail 81 to move towards or away from the human eye.

[0031] When implementing the present solution, an inclined slide 31, a third motor 3232 and a slider 8 are set. The third motor 3232 drives the slider 8 to move by meshing the gear and the rack. The present solution preferably uses a bevel gear 321 and a bevel rack 322. This structure can make the slide smoother and the sliding speed uniform when the slide is slid. When implementing the present solution, those skilled in the art can position the bevel rack 322 and the bevel gear 321 by setting guide rails, guide grooves, magnetic attraction, etc. to avoid poor contact between the bevel gear 321 and the bevel rack 322. If no guide grooves or guide rails are set, magnetic attraction materials can preferably be used to make the bevel gear 321 or the bevel rack 322 so that the two can generate magnetic attraction to each other after contact.

[0032] Each of the slit lamp assemblies 3 includes a lamp body 33, an upper top plate 34 arranged at a corresponding upper position of the lamp body 33, and a lower bottom plate 35 arranged at a corresponding lower position of the lamp body 33. A limiting ring 36 for limiting the upper and lower positions of the arc guide rail 81 is formed between the upper top plate 34 and the lower bottom plate 35. A plurality of groups of balancing rollers 37 are arranged between the arc guide rail 81 and the limiting ring 36. The outer peripheral wall of the balancing roller 37 abuts against the inner peripheral wall of the arc guide rail 81 and can roll along the inner peripheral wall of the arc guide rail 81.

[0033] When the present scheme is implemented, the slit lamp assembly 3 moves along the arc guide rail 81, and the balancing roller 37 rolls on the inner wall of the arc guide rail 81 to ensure that the slit lamp assembly 3 can move smoothly. The design of the limiting ring 36 prevents the slit lamp assembly 3 from shaking up and down during movement, thereby further improving the stability of movement. Through this structural design, the slit lamp assembly 3 can achieve precise and smooth movement on the arc guide rail 81. The number of balancing rollers 37 of the present scheme is preferably four, and they are respectively arranged in four different directions of the slit lamp to ensure that the slit lamp does not shake when sliding.

[0034] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
