Description
Technical Field
[0001] This application relates to the technical field of edging machines, and in particular to an eyeglass lens edging machine. Background Technology
[0002] With modern people's increasing focus on vision health and personalized needs, the eyewear industry has experienced rapid development in recent years. In particular, the manufacturing and processing technology of eyeglass lenses not only requires high precision and efficiency but also must meet the personalized needs of different consumers, driving continuous upgrades and innovations in lens processing equipment. In the eyewear production process, the lens edging process is a crucial step, directly affecting the appearance, wearing comfort, and lifespan of the eyeglasses.
[0003] In the existing technology, lenses are polished using an edging machine. During the edging process, the debris generated may adhere to the lens surface. If the water does not wash away the debris adhering to the lens surface, the operator may cause the debris to rub against the lens surface when wiping the lens with a spectacle cloth, resulting in scratches and wear on the lens. Summary of the Invention
[0004] To address the problem that debris easily adheres to the lens surface during lens edging and is difficult to rinse off with water, this application provides a spectacle lens edging machine.
[0005] The eyeglass lens edging machine provided in this application adopts the following technical solution: A spectacle lens edging machine includes a machine body and a connecting component. The machine body has an operating cavity containing a grinding wheel and a water spray pipe. The connecting component includes a connecting block bonded to the lens using double-sided adhesive. A mounting rod and a clamping rod are respectively provided on opposite inner sides of the operating cavity for fixing the lens. An installation groove is formed on the inner wall of the operating cavity. The mounting rod includes a fixing rod fixed within the installation groove, and a movable sleeve is hinged to one end of the fixing rod near the clamping rod. A movable rod is inserted through the movable sleeve. A locking block for connecting the connecting block is installed at the end of the movable rod near the clamping rod. A motor is installed inside the movable rod, and the output end of the motor is fixedly connected to the locking block. An installation sleeve is slidably installed on the machine body along its own length direction through the installation groove. The installation sleeve is sleeved on the outer periphery of the installation rod. An ultrasonic cleaning box is installed on the inner bottom surface of the operating cavity. The machine body is provided with a rotating component for driving the movable rod to rotate downward and a driving component for pushing the movable rod to move downward.
[0006] By adopting the above technical solution, the mounting sleeve is moved towards the clamping rod, so that the mounting sleeve is fitted around the outer periphery of the fixed rod and the movable sleeve. The mounting rod is in a horizontal state. The connecting block is bonded to the lens using double-sided adhesive, and then the connecting block is fixedly connected to the locking block. The clamping rod is then used to abut and position the other side of the lens. The motor is started, and the motor drives the lens to rotate through the locking block and the connecting block, so that the grinding wheel can grind the edge of the lens. After grinding is completed, the mounting sleeve is moved away from the clamping rod. The rotating component drives the movable sleeve to rotate downward, and the driving component drives the movable rod to move downward, so that the lens enters the ultrasonic cleaning box, thereby cleaning the lens and reducing the possibility of debris adhering to the lens, thus reducing the possibility of scratches and wear on the lens.
[0007] Preferably, a slider is fixed on the outer circumferential surface of the movable rod, and a groove is formed on the inner circumferential surface of the movable sleeve. The slider slides and engages with the movable sleeve along the length direction of the movable sleeve through the groove. A magnetic block one is fixed at one end of the movable rod near the fixed rod, and a magnetic block two for attracting the magnetic block one is fixed on the inner end face of the movable sleeve near the fixed rod.
[0008] By adopting the above technical solution, the slider and the groove limit the moving rod, so that the moving rod moves along the length direction of the moving sleeve. When the moving rod is in a horizontal state, the first magnetic block and the second magnetic block attract each other, so that the locking block does not move in the horizontal direction, so as to facilitate the edge grinding of the lens.
[0009] Preferably, the side of the locking block near the clamping rod has a square groove for inserting the connecting block, and the inner wall of the square groove has a insertion groove. The locking block slides and the connecting block is installed through the insertion groove. The outer side of the connecting block has a connecting groove for inserting the connecting block. A reset block is fixed to the side of the connecting block. The inner wall of the insertion groove has a reset groove. The reset block slides and engages with the locking block through the reset groove. A reset spring is fixed to the side of the reset block away from the connecting block. The end of the reset spring away from the reset block is fixedly connected to the inner wall of the reset groove. An inclined surface is provided on the side of the connecting block near the connecting block. The inclined surface is located at the end of the connecting block away from the moving rod.
[0010] By adopting the above technical solution, the connecting block is inserted into the square groove. The connecting block pushes the plug into the plug groove through the inclined surface. When the connecting block abuts against the bottom surface of the square groove, the plug is inserted into the plug groove under the elastic force of the return spring, thereby realizing the snap-fit and fixation of the connecting block and the locking block, and thus realizing the fixation of the lens.
[0011] Preferably, a rotating ring is fitted on the outer circumferential surface of the card block, the rotating ring is rotatably connected to the card block, and four pull ropes are fixed on the inner circumferential surface of the rotating ring. Each pull rope corresponds to a plug block, and the end of the pull rope away from the rotating ring is fixedly connected to the corresponding plug block.
[0012] By adopting the above technical solution, when the lens needs to be removed after the edge grinding is completed, the rotating ring is rotated. The rotating ring drives the plug block to move away from the connecting block through the pull rope, so that the plug block is disengaged from the connecting groove, so that the connecting block is disengaged from the square groove, and the lens can be quickly disassembled.
[0013] Preferably, the rotating assembly includes a crossbar fixed to the inner wall of the operating cavity, a cylinder is installed at the bottom of the crossbar, a push roller is installed at the bottom end of the piston rod of the cylinder, the push roller can abut against the movable sleeve, and a horizontally arranged limiting rod is fixed to the inner wall of the operating cavity, the limiting rod is located below the fixed rod, and the limiting rod can abut against the outer peripheral surface of the movable sleeve.
[0014] By adopting the above technical solution, cylinder one is activated, and the piston rod of cylinder one drives the push roller to move downward. The push roller abuts against the moving sleeve and pushes the moving sleeve to rotate downward. When the moving sleeve rotates downward by 90 degrees, the moving sleeve abuts against the limit rod, so that the lens is located directly above the ultrasonic cleaning box.
[0015] Preferably, the driving component includes a limiting block, a dovetail groove is formed on the side of the limiting block near the moving rod, a dovetail block is vertically slidably mounted on the limiting block through the dovetail groove, a pressing groove is formed on the side of the dovetail block near the moving rod, a pressing block is slidably mounted on the dovetail block along its own length direction through the pressing groove, a pressing spring is fixed on the side of the pressing block away from the moving rod, one end of the pressing spring away from the pressing block is fixedly connected to the inner wall of the pressing groove, and the pressing block can abut against the side of the rotating ring near the moving rod.
[0016] By adopting the above technical solution, when the movable sleeve rotates downward by 90 degrees, the pressing block abuts against the movable sleeve. When the pressing block moves downward to between the rotating ring and the movable rod, the pressing block moves towards the movable rod under the elastic force of the pressing spring. The pressing block continues to move downward and abuts against the rotating ring, thereby pushing the rotating ring downward, so that the lens moves downward into the ultrasonic cleaning box.
[0017] Preferably, a limiting spring is fixed to the bottom surface of the dovetail block, the bottom end of the limiting spring is fixedly connected to the inner bottom surface of the dovetail groove, a positioning block is fixed to the top surface of the dovetail block, and an electromagnet is fixed to the inner top surface of the dovetail groove. When the electromagnet is energized, it repels the positioning block.
[0018] By adopting the above technical solution, when the moving sleeve is in a horizontal state, the electromagnet is de-energized, and the dovetail block is located at the top of the limiting block under the elastic force of the limiting spring. When the moving sleeve rotates down 90 degrees, the electromagnet is energized and works. The electromagnet and the positioning block repel each other, and the positioning block drives the dovetail block to move down, so that the pressing block can drive the lens to move down.
[0019] Preferably, cylinder two and cylinder three are installed in the machine body. The piston rod end of cylinder two is fixedly connected to the end of the clamping rod away from the mounting rod, and the piston rod end of cylinder three is fixedly connected to the end of the mounting sleeve away from the clamping rod.
[0020] By adopting the above technical solution, the mounting sleeve is sleeved on the outer periphery of the mounting rod under the drive of cylinder three, so that the mounting rod is in a horizontal state, and the clamping rod moves towards the lens under the drive of cylinder two, thereby limiting the lens.
[0021] Preferably, a water-proof ring is fixed to the end face of the mounting sleeve near the clamping rod, and the water-proof ring can abut against the outer arc surface of the lens.
[0022] By adopting the above technical solution, when the installation sleeve is fitted onto the outer periphery of the fixed rod and the movable sleeve, the water-proof ring abuts against the outer arc surface of the lens, reducing the possibility of water wetting the double-sided adhesive during the edge grinding process, thereby ensuring a more secure connection between the lens and the connecting block.
[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. Move the mounting sleeve towards the clamping rod so that it fits around the outer periphery of the fixed rod and the movable sleeve. The mounting rod is in a horizontal position. Use double-sided tape to bond the connecting block to the lens. Then, fix the connecting block to the locking block. Use the clamping rod to abut and position the other side of the lens. Start the motor. The motor drives the lens to rotate through the locking block and the connecting block, so that the grinding wheel can grind the edge of the lens. After grinding, move the mounting sleeve away from the clamping rod. The rotating component drives the movable sleeve to rotate downward. The drive component drives the movable rod to move downward, so that the lens enters the ultrasonic cleaning box, thereby cleaning the lens and reducing the possibility of debris adhering to the lens, thus reducing the possibility of scratches and wear on the lens. 2. Insert the connecting block into the square groove. The connecting block pushes the insertion block into the insertion groove through the inclined surface. When the connecting block abuts against the bottom surface of the square groove, the insertion block is inserted into the insertion groove under the elastic force of the return spring, thereby realizing the snap-fit and fixation of the connecting block and the locking block, and thus fixing the lens. 3. When the movable sleeve rotates downwards by 90 degrees, the pressing block comes into contact with the movable sleeve. When the pressing block moves downwards to between the rotating ring and the movable rod, the pressing block moves towards the movable rod under the elastic force of the pressing spring. The pressing block continues to move downwards and comes into contact with the rotating ring, thereby pushing the rotating ring downwards, so that the lens moves downwards into the ultrasonic cleaning box.

The clamping rod 14 is used to abut and position the other side of the lens. The motor 333 is started. The motor 333 drives the lens to rotate through the locking block 4 and the connecting block 21, so that the grinding wheel 12 can grind the edge of the lens. After grinding is completed, the mounting sleeve 17 is moved away from the clamping rod 14. Then the movable sleeve 32 is rotated downward. The pressing block 67 drives the movable rod 33 to move downward, so that the lens enters the ultrasonic cleaning box 19, thereby cleaning the lens and reducing the possibility of debris adhering to the lens, thereby reducing the possibility of scratches and wear on the lens.
