Technical Field

[0001] The utility model relates to the technical field of mouth mirror assembly, in particular to a lens assembly structure and mouth mirror assembly equipment. Background Art

[0002] The emergence of oral endoscopes has brought a new model for oral examination and treatment. Oral mirrors are commonly used tools in oral examination and treatment. Correct use of dental mirrors can help dentists or individuals better observe oral conditions. When producing oral mirrors, the lenses need to be pressed.

[0003] Currently, when assembling mouth mirrors, assembly equipment is required to press the lenses onto the mouth mirror components. However, during the press-fitting process, an additional control system and power source are required to position the tooling that carries the workpiece, which increases the equipment cost.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a lens assembly structure and a mouth mirror assembly device are provided. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lens assembly structure, including a frame and a positioning assembly, a transfer assembly is provided on the upper part of the frame, and a cylinder is provided in the middle of the transfer assembly, a lifting plate is fixed to the bottom of the cylinder, and the top of the lifting plate is connected to a guide rod, a vacuum adsorption head is placed on the bottom of the lifting plate, and the positioning assembly is arranged on both sides of the frame, and the positioning assembly includes a fixed plate, a sliding rod, a first spring, a second spring, a baffle, a sliding column, a pressure plate and an anti-slip pad, the two ends of the fixed plate are internally slidably connected to the sliding rod, and the upper end of the sliding rod is sleeved with the first spring, the lower end of the sliding rod is sleeved with the second spring, and the top of the second spring is connected to the baffle, sliding columns are placed on both sides of the lifting plate, the bottom of the sliding rod is fixed with a pressure plate, and the bottom of the pressure plate is provided with an anti-slip pad.

[0007] Furthermore, the baffle is slidably connected to the slide rod, and one side of the middle portion of the baffle is convex.

[0008] Furthermore, the transfer assembly includes a motor and a lead screw. The motor is placed on one side of the upper portion of the frame, and one end of the motor is connected to the lead screw.

[0009] Furthermore, the transfer assembly also includes a slide and a polished rod. The slide is provided on the outer side of the lead screw, and the polished rod is slidably connected to the interior of one end of the slide.

[0010] Furthermore, stabilizing components are provided at both ends of the fixing plate, and the stabilizing components include a fixing frame and a screw rod. The fixing frames are connected to both ends of one side of the fixing plate, and the internal threads of the fixing frame are connected to the screw rod.

[0011] Furthermore, the stabilizing assembly also includes a slider and a rubber pad. The end of the screw is rotatably connected to the slider, and a rubber pad is provided on one side of the slider.

[0012] Furthermore, the slider is slidably connected to the fixing plate, and one side of the slider is arc-shaped.

[0013] A mouth mirror assembly device is provided, wherein the mouth mirror assembly device is equipped with the lens assembly structure described above.

[0014] The utility model provides a lens assembly structure and a mouth mirror assembly device, which have the following beneficial effects:

[0015] 1. The present invention adopts the positioning assembly. When the cylinder drives the lifting plate downward and the vacuum adsorption head presses the lens onto the carrier, the lifting plate will squeeze the baffle through the sliding column, and the second spring can drive the pressure plate downward. As a result, before the lens contacts the workpiece on the carrier, the pressure plate can press the carrier into position, thereby enhancing the stability after subsequent press-fitting. After press-fitting, when the cylinder drives the lifting plate upward to reset, the first spring will push the slide bar, causing the pressure plate to move upward, thereby automatically releasing the restriction on the carrier, thereby improving the convenience of use.

[0016] 2. The utility model is provided with a stabilizing assembly. When the screw is rotated, the screw drives the slider to move under the limit of the fixed frame, so that the rubber pad contacts the slide bar, which can provide a certain friction resistance between the slide bar and the fixed plate, avoiding the slide bar from vibrating up and down under the action of the spring after the slide column is separated from the baffle, thereby enhancing the stability of the slide bar after the reset. Moreover, when the friction resistance of the rubber pad becomes low due to wear, the friction resistance can be adjusted by rotating the screw to ensure the normal operation of the stabilizing assembly.

After pressing and mounting, when the cylinder 3 drives the lifting plate 4 to move up and reset, the first spring 703 will push the slide bar 702, causing the pressure plate 707 to move up, thereby automatically releasing the restriction on the loading tooling. Finally, when the slide column 706 is separated from the baffle 705, the rubber pad 804 can enhance the stability of the slide bar 702 after it is reset, and when the friction resistance of the rubber pad 804 becomes lower due to wear, by rotating the screw 802, it can drive the slider 803 to move under the limit of the fixed frame 801, thereby increasing the pressure between the rubber pad 804 and the slide bar 702, thereby adjusting the friction resistance between the slide bar 702 and the fixed plate 701 to ensure the normal operation of the stabilization component 8.
