[0015] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-4 A center positioning clamping device for an original lens of an eyeglass comprises a control system, a rocker arm system 100, a clamping system 200 and a base assembly 300, wherein the rocker arm system 100 is mounted on the base assembly 300, the clamping system 200 is mounted on the rocker arm system 100, and the control system is communicatively connected with the rocker arm system 100 and the clamping system 200 respectively.

[0017] The rocker arm system 100 includes a base plate 105 connected to the base assembly 300, a motor 104 is fixed to the lower side of the base plate 105, a column seat 103 is installed on the upper side of the base plate 105, a bearing 102 is installed in the column seat 103, the main shaft of the motor 104 passes through the bearing 102 and is connected to the column 101, a rotating arm 106 and a return spring 110 are sleeved on the column 101, an end face cam 108 is fixed to the top of the column 101, and a cam push rod 107 and a center positioning column 109 are installed on the rotating arm 106.

[0018] The clamping system 200 includes a rotating shaft 203 connected to the column 101 , the rotating shaft 203 is connected to the clamping head 202 , the rotating shaft 203 is connected to the suction cup mounting seat 201 , and the clamping head 202 and the positioning column 204 are installed on the suction cup mounting seat 201 .

[0019] The base assembly 300 includes a center positioning sleeve 301 fixed on the bottom plate 105, and a lens holder 303 is arranged on the upper side of the center positioning sleeve, and the lens 400 is placed on the lens holder 303. The bottom plate 105 is installed with a fixing column 306 and a limiting column 305, and a test platform bottom plate 302 is fixed on the fixing column 306, and the test platform bottom plate 302 is connected to the lens holder 303. The lens holder 303 is provided with an anti-slip rubber head 304.

[0020] When clamping the original lens of the glasses, the lens holder 303 is placed on the test platform base plate 302. In order to better fix the lens holder 303, a holder groove that matches the shape of the lens holder 303 can be provided on the test platform base plate 302. The lens 400 is placed on the lens holder 303, and the motor 104 drives the rotating arm 106 to move. Further, when the center positioning column 109 contacts the center positioning sleeve 301, the rotating arm 106 stops rotating. At this time, the end face cam 108 continues to rotate under the drive of the motor 104. Further, the cam push rod 107 moves along the end face of the end face cam 108. Under the joint action of the cam push rod 107, the end face cam 108 (which is the prior art, and the end face has an inclined boss) and the center positioning sleeve 301, the rotating arm 106 compresses the reset spring 110 and moves downward, so that the clamping head 202 sticks to the upper lens 400, and the clamping is completed.

[0021] After clamping is completed, under the drive of the motor 104 and the action of the return spring 110, the rotating arm 106 starts to move upward. When the center positioning column 109 is separated from the center positioning sleeve 301, the rotating arm 106 moves toward the initial position until the center positioning column 109 contacts the limit column 305 and stops moving.

[0022] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be included in the protection scope of the utility model.
