Description

Technical Field

[0001] This utility model relates to the field of lens edging machine technology, specifically to a waterproof cover for an eyeglass lens edging machine with automatic shut-off and status detection functions. Background Technology

[0002] In the process of grinding eyeglass lenses, a waterproof cover is usually installed on the outside of the grinding mechanism to prevent water splashes (coolant) and lens powder generated during grinding from contaminating the equipment and working environment, and to ensure operational safety. However, the currently widely used traditional waterproof cover design has significant drawbacks, mainly relying on manual opening and closing.

[0003] In existing technologies, some devices use motors, springs, or counterweights to achieve automatic return of the waterproof cover, but these methods are complex and lack reliability. Furthermore, some high-end devices may use sensors to detect the status of the waterproof cover, but this is costly and unsuitable for ordinary edge grinding machines. Therefore, a simple, reliable, and status-detection-enabled automatic shut-off solution is needed. Summary of the Invention

[0004] The purpose of this invention is to address the problem that existing waterproof covers require manual opening and closing, and to provide a waterproof cover for an eyeglass lens edging machine with automatic closing and status detection functions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a waterproof cover for an eyeglass lens edging machine with automatic closing and status detection functions, comprising:

[0006] The waterproof cover body is rotatably mounted on the head of the edge grinding machine via a rotating shaft;

[0007] A cam is located at the first end of the rotating shaft. The profile of the cam is an involute or eccentric arc structure, and its working surface is in contact with the original synchronous belt of the grinding machine.

[0008] The micro switch status detection mechanism includes a protruding structure fixed on the second end of the rotating shaft and a micro switch that cooperates with it. The micro switch is fixed to the frame of the grinding machine, and its signal output terminal is connected to the equipment control system.

[0009] Furthermore, the profile of the cam includes a working profile segment and a disengagement profile segment:

[0010] When the timing belt moves along the first direction, it contacts the working profile section of the cam and drives the cam to rotate, thereby causing the waterproof cover body to rotate in the closing direction;

[0011] When the waterproof cover body is rotated to the closed position, the disengagement profile of the cam is located opposite to the timing belt, causing the timing belt to disengage from the cam.

[0012] Furthermore, the rotation trajectory of the protruding structure matches the trigger terminal of the micro switch:

[0013] When the waterproof cover is fully opened, the protruding structure triggers a micro switch, sending a signal to the control system.

[0014] When the waterproof cover is fully closed, the raised structure disengages from the microswitch.

[0015] Furthermore, the water cover body is made of a transparent or semi-transparent material.

[0016] Furthermore, the cam can be replaced with a friction wheel or gear, which is connected to the synchronous belt drive through meshing or frictional contact.

[0017] Furthermore, the micro switch can be replaced with a Hall sensor or a photoelectric sensor;

[0018] When a Hall sensor is used, a magnet is provided on the protruding structure;

[0019] When a photoelectric sensor is used, the protruding structure is used to block the light path.

[0020] The beneficial effects of this utility model after adopting the above technical solution are as follows: The waterproof cover is closed by utilizing the power of the grinding machine itself. When the synchronous belt moves, the working contour section of the cam is driven, automatically closing the waterproof cover to its position, eliminating the need for manual closing by the operator. The operator does not need to manually operate the cover near the grinding area when the equipment is started or running, avoiding potential hand injury risks. Attached Figure Description

[0026] See Figure 1-3 As shown, the technical solution adopted in this specific embodiment is: a waterproof cover for an eyeglass lens edging machine with automatic closing and status detection functions, comprising:

[0027] The waterproof cover body 1 is rotatably mounted on the head of the edge grinding machine via a rotating shaft 2. In this embodiment, the waterproof cover body is made of transparent or semi-transparent material.

[0028] Cam 3 is located at the first end of rotating shaft 2. The profile of cam 3 is an involute or eccentric arc structure, and its working surface is in contact with the original synchronous belt of the grinding machine.

[0029] The micro switch 5 state detection mechanism includes a protruding structure 4 fixed to the second end of the rotating shaft 2 and a cooperating micro switch 5. The micro switch 5 is fixed to the edge grinding machine frame, and its signal output terminal is connected to the equipment control system. The rotation trajectory of the protruding structure 4 matches the trigger terminal of the micro switch 5: when the waterproof cover body 1 is fully open, the protruding structure 4 triggers the micro switch 5, sending a signal to the control system. When the waterproof cover body 1 is fully closed, the protruding structure 4 disengages from the micro switch 5.

[0030] The specific profile of cam 3 includes working profile segment 31 and disengagement profile segment 32:

[0031] When the timing belt moves along the first direction, it contacts the working contour section 31 of the cam 3 and drives the cam 3 to rotate, thereby causing the waterproof cover body 1 to rotate in the closing direction;

[0032] When the waterproof cover body 1 is rotated to the closed position, the disengagement profile 32 of the cam 3 is located opposite to the timing belt, so that the timing belt disengages from the cam 3.

[0033] The cam 3 can be replaced with a friction wheel or gear, connecting to the synchronous belt drive via meshing or frictional contact. This provides different power transmission options to accommodate various synchronous belt types.

[0034] The micro switch 5 can be replaced with a Hall sensor or a photoelectric sensor; it provides different detection methods to adapt to different environmental requirements.

[0035] When a Hall sensor is used, a magnet is provided on the protruding structure 4;

[0036] When a photoelectric sensor is used, the protruding structure 4 is used to block the light path.

[0037] The working principle of this utility model:

[0038] 1. Standby / Lens insertion / removal status (waterproof cover on):

[0039] When the operator needs to place or remove the lens, they manually lift the waterproof cover body 1, rotating it around the rotating shaft 2 to the fully open position. At this time, as the waterproof cover body 1 opens, the protruding structure 4 fixed to the second end of the rotating shaft 2 disengages from the trigger position of the micro switch 5.

[0040] Microswitch 5 sends a "cover open" signal to the equipment control system. Upon receiving this signal, the control system can either display the "cover open" status on the operation panel or directly disable the grinding machine from starting, preventing accidental start-up of the equipment when the cover is open.

[0041] 2. Start edge grinding / trigger automatic shutdown:

[0042] The operator places the lens and starts the edging program on the control system. The main motor of the edging machine starts, driving the timing belt to move along the first direction (the first direction usually refers to the grinding working direction). The moving timing belt contacts the working contour section 31 of the cam 3, and the contact force between the timing belt and the working contour section 31 of the cam 3 generates friction, driving the cam 3 to rotate around the rotating shaft 2. The rotation of the cam 3 drives the entire rotating shaft 2 to rotate, thereby pulling the waterproof cover body 1 to rotate in the closing direction.

[0043] 3. Closing in place and disengaging:

[0044] As cam 3 is continuously driven to rotate by the timing belt, the waterproof cover body 1 gradually rotates downwards. When the waterproof cover body 1 is fully rotated and covers the grinding area, cam 3 rotates to the disengagement section 32, and cam 3 releases contact with the timing belt. Due to the change in the contact state between the disengagement section 32 and the timing belt, the contact force between the timing belt and cam 3 disappears or is insufficient to maintain the drive, and the two automatically disengage. At this time, the timing belt continues to operate normally, but no longer exerts force or friction on cam 3 and the waterproof cover, avoiding continuous interference and wear.

[0045] Meanwhile, at the second end of the rotating shaft 2:

[0046] As the rotating shaft 2 rotates to the closed position, the protruding structure 4 on it also rotates to a specific angle. This angle causes the protruding structure 4 to trigger the micro switch 5, which changes its state and sends a "cover closed" signal to the control system.

[0047] 4. Safe operating status (waterproof cover closed and locked):

[0048] After receiving the "cover closed" confirmation signal, the control system allows the edge grinding program to continue or to officially begin the grinding process.

[0049] During the edge grinding process, if the control system detects that the micro switch 5 is triggered again (i.e., the "cover open" signal), it will immediately stop the edge grinding machine and the timing belt to prevent processing from continuing when the cover is open.

[0050] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
