Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser equipment, and in particular to a lens feeding and film-tearing device. Background Technology
[0002] Before laser cleaving, sapphire optical lenses need to be precisely delivered to a designated position with an error margin of 0.03. This is because the high temperatures during laser cleaving often cause the lens to split along the pre-cut line, making subsequent cleaving difficult. Therefore, a blue coating is applied to the sapphire optical lens before feeding it for cleaving. This solves the problem of the sapphire optical lens scattering during cleaving.
[0003] However, after applying the film, it must be removed at the crack location. This is because high-temperature cracking would cause the blue film to adhere to the sapphire lens, which is unacceptable. Therefore, it is necessary to precisely position the workpiece while simultaneously removing the film beneath the sapphire lens. Utility Model Content
[0004] The technical problem to be solved by this utility model embodiment is to provide a lens feeding and film-removing device so as to realize film removal while conveying the lens.
[0005] To solve the above-mentioned technical problems, this utility model provides a lens feeding and film-tearing device, including a screw drive mechanism, a lens clamp, a support frame, and a winding mechanism. The lens clamp is mounted on the screw drive mechanism, and the winding mechanism is correspondingly mounted on the support frame. The winding mechanism includes a winding roller and a stall motor connected to the winding roller.
[0006] Furthermore, a pressure plate mechanism is provided above the lens clip to apply pressure and limit the movement of the lens on the lens clip.
[0007] Furthermore, the pressure plate mechanism includes a pressure plate, a spring, and bolts. The pressure plate is mounted on the support frame by bolts; the spring is mounted on the bolts and applies downward pressure to the pressure plate.

[0015] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0016] In this embodiment of the invention, directional indicators (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicators will also change accordingly.
[0017] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
[0018] Please refer to Figures 1-3 The lens feeding and film-tearing device of this utility model embodiment includes a screw drive mechanism, a lens clamp, a support frame, and a winding mechanism.
[0019] The lens is mounted on a lead screw drive mechanism and is used to hold lenses with blue coating. The lead screw drive mechanism drives the lens clamp, precisely transporting the lens to the designated position. The lead screw drive mechanism uses a servo motor lead screw.
[0020] The winding mechanism is used to roll up the torn blue film. The winding mechanism is mounted on the support frame. It includes a winding roller and a stalled motor connected to the winding roller. The winding roller is mounted on the support frame via bearings. The torque of the stalled motor is fixed, ensuring that the tension applied by the winding roller to the blue film is just enough to tear it, without excessive force that would break the film.
[0021] In one implementation, a pressure plate mechanism is provided above the lens clip to apply pressure and limit the movement of the lens on the lens clip. The pressure plate mechanism includes a pressure plate, a spring, and a bolt. The pressure plate is mounted on the support frame by the bolt; the spring is mounted on the bolt and applies downward pressure to the pressure plate. The lens clip applies slight pressure to the lens, causing the lens to adhere to the lens clip and achieve a flattening effect.
[0022] In one implementation, a tray is provided above the lead screw drive mechanism. The tray is used to hold the receiving box.
[0023] The working principle of this invention is as follows: Lenses with the applied film are placed in the tray, and the last row is clamped into the lens holder; a screw drive mechanism is used for precise driving of the lens holder. The front end of the blue film on the lens is pre-wound onto the winding roller, and then the stall motor is activated, forcibly separating the blue film from the lens. After the screw drive mechanism stops, the stall motor also stalls due to resistance; as the lens holder moves forward, the film loosens, and the stall motor continues winding. This process is repeated automatically until the lens is repaired.
[0024] This invention is applicable to lens-type split lenses such as sapphire and quartz.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
