Description

Technical Field

[0001] The utility model relates to the technical field of optical lens production equipment, in particular to an optical lens centering and edge grinding machine. Background Art

[0002] An optical lens is an optical element made of transparent material (such as glass, crystal, etc.). The convex lens is thick in the middle and thin at the edge. There are three types: biconvex, plano-convex, and concave-convex. The concave lens is thin in the middle and thick at the edge. There are three types: biconcave, plano-concave, and convex-concave. Lenses play an important role in astronomy, military, transportation, medicine, art and other fields.

[0003] After the optical lens is cast, it needs to be cut, polished and other processes to obtain the final product. When polishing the optical lens, an edge grinder is generally used. The edge grinder is divided into a fully automatic edge grinder and a semi-automatic edge grinder. When using a semi-automatic edge grinder, the optical lens needs to be manually centered, that is, the center of the optical lens is determined. After the manual centering is completed, the optical lens is placed in the edge grinder for polishing.

[0004] Therefore, the existing semi-automatic edge grinding machines for optical lens processing have the technical defect of being unable to automatically center the optical lens, and manual centering is relatively time-consuming, which affects the processing efficiency. Summary of the invention

[0005] The utility model provides an optical lens centering and edge grinding machine to solve the problems raised in the above background technology.

[0006] The technical solution of the utility model is achieved in this way:

[0007] An optical lens centering and edge grinding machine comprises a housing, a fixture, a grinding mechanism and a centering mechanism;

[0010] By adopting the above technical solution, the centering mechanism centers the optical lens and positions the center of the optical lens at the center of the fixture. Then the fixture clamps the optical lens and the polishing mechanism polishes the optical lens, thereby automatically centering the optical lens instead of manually, reducing manual labor intensity and improving work efficiency.

[0011] Preferably, the centering mechanism is mainly composed of a first interference wheel, a cross frame, a spring, a swing rod, a second interference wheel, a conical wheel and a second screw rod. There are two swing rods, which rotate in the front and rear ends of the housing respectively. The middle end of the swing rod has a second interference wheel that rotates through a rotating shaft.

[0013] By adopting the above technical solution, the second screw can move laterally when the second screw is rotated, and the second screw drives the conical wheel to move laterally, thereby causing the conical wheel to push the rocker arm to rotate. When the two rocker arms approach each other, the two first contact wheels and the two second contact wheels can be brought close to each other. When the optical lens is inserted downward between the two first contact wheels and the two second contact wheels around the clamp, the center of the optical lens can be limited to be consistent with the center of the two first contact wheels and the two second contact wheels, thereby limiting the center of the optical lens to be located in the center of the clamp, thereby achieving the purpose of centering.

[0019] By adopting the above technical solution, the third screw can be moved horizontally to the left and right when the third screw is rotated, so that the second lens contact head can cooperate with the first lens contact head to clamp the optical lens, and when the first lens contact head drives the optical lens, the second lens contact head can follow the rotation without driving the third screw to rotate, and thus will not interfere with the stability of the third screw.

[0020] Preferably, the rotation center line of the second lens contact head and the first lens contact head is located directly below the material discharge notch;

[0021] By adopting the above technical solution, when the optical lens is placed downward from the material discharge gap, the optical lens can fall between the second lens contact head and the first lens contact head, that is, fall in the center of the fixture.

[0038] There are two second screw rods 37 arranged in parallel. One end of the second screw rod 37 passes through one side of the housing 5 through a thread, and the other end of the second screw rod 37 passes through the other side of the housing 5 movably. A conical wheel 36 is provided on the middle end of the second screw rod 37. The vertical section of the conical wheel 36 is shown in FIG. Figure 5 , the two conical wheels 36 respectively abut against the sides of the two swing rods 34 that are away from each other, and the centering mechanism 3 limits the center of the optical lens to the center of the fixture;

[0039] Clamp: The material discharge notch 1 is located directly above the clamp, and the grinding mechanism 6 is located directly below the clamp. Specifically, the clamp is mainly composed of a power clamp 2 and a fixed clamp 7. For details, see Figure 4 , the power clamp 2 and the fixed clamp 7 are respectively installed in the left and right ends of the housing 5, and the two first contact wheels 31 and the two second contact wheels 35 are arranged in a circular array around the center of the power clamp 2 and the fixed clamp 7;

[0040] The power clamp 2 is mainly composed of a first screw 21, a first motor 22 and a first lens contact head 23. Figure 4 The first screw 21 is threaded through the left side wall of the housing 5. The first screw 21 is located at one end of the housing 5 and is fixed with a first motor 22. The input end of the first motor 22 is electrically connected to the output end of the controller 4. The output end of the first motor 22 rotates through the end of the first screw 21 and is fixed with a first lens contact head 23. Two first contact wheels 31 and two second contact wheels 35 are arranged in a circular array around the center of the first lens contact head 23.

[0041] The fixed fixture 7 includes a second lens contact head 71 and a third screw 72. Figure 4 , the third screw 72 is threaded through the right side wall of the housing 5, and the second lens contact head 71 is rotated inside one end of the third screw 72 located in the housing 5, and the rotation center line of the second lens contact head 71 and the first lens contact head 23 are located on the same straight line, that is, the two first contact wheels 31 and the two second contact wheels 35 are arranged in a circular array around the center of the second lens contact head 71;

[0042] The rotation center line of the second lens contact head 71 and the first lens contact head 23 is located directly below the material discharge gap 1 .

[0043] Working principle:

[0044] When in use, first rotate the second screw 37, and the second screw 37 moves to the right while rotating. At this time, the second screw 37 drives the conical wheel 36 to move to the right. When the conical wheel 36 moves to the bottom of the swing rod 34, it gradually pushes the swing rod 34, so that the swing rod 34 rotates, and the two swing rods 34 approach each other, so that the two first contact wheels 31 and the two second contact wheels 35 approach each other. Since the cross-frame 32 can move forward and backward, the semi-finished product of the optical lens can be inserted downward from the discharge gap 1 to between the two first contact wheels 31, and after passing between the two first contact wheels 31, it is finally stuck between the two first contact wheels 31 and the two second contact wheels 35, so as to achieve the purpose of centering.

[0045] Then, the first screw 21 and the third screw 72 are rotated, and the first screw 21 and the third screw 72 are moved closer to each other, thereby driving the first lens contact head 23 and the second lens contact head 71 to move closer to each other to clamp the optical lens. At this time, the second screw 37 is rotated in the opposite direction to make the conical wheel 36 leave the swing rod 34. The swing rod 34 loses support, and the swing rod 34 rotates in the opposite direction due to gravity, so that the two first contact wheels 31 and the two second contact wheels 35 leave the optical lens.

[0046] The controller 4 controls the electric push rod 64 to be energized, and the electric push rod 64 pushes the lifting seat 63 to move up and down, so that the second motor 61 and the grinding wheel 62 move up and down, so that the grinding wheel 62 contacts the optical lens. The controller 4 controls the second motor 61 to be energized, and the second motor 61 drives the grinding wheel 62 to rotate to grind the optical lens. The controller 4 controls the first motor 22 to drive the first lens contact head 23 to rotate, and then drives the optical lens to rotate, so as to grind different parts of the optical lens.

[0047] After the grinding is completed, the first screw 21 and the third screw 72 are rotated in the opposite direction to take out the grinded optical lens from the discharge notch 1 .

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
