Description

Technical Field

[0001] This utility model belongs to the field of optical mold technology, specifically relating to an optical mold edge grinding device. Background Technology

[0002] In the polishing process of optical molds, the polishing devices are mainly divided into pure electric drive and pure manual operation. Electric polishing devices mainly rely on motor drive, which consumes a lot of energy. In addition, since coolant or lubricant is used to flush the polished surface during the polishing process, water can easily enter the motor and circuit parts and cause short circuits, resulting in equipment damage and high maintenance costs. Manual polishing, on the other hand, relies entirely on manual operation. Workers are prone to fatigue after working for a long time, resulting in low efficiency. Furthermore, when manually rotating the mold, the rotation frequency is unstable, which can easily lead to uneven polishing force, affecting the surface accuracy of the mold, and may even cause excessive wear. Utility Model Content

[0003] The purpose of this invention is to provide an optical mold edge grinding device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an optical mold edge grinding device, comprising a worktable, a first fixed frame on the top of the worktable, a grinding disc rotatably mounted on the top of the first fixed frame, a plurality of suction cups on the top of the grinding disc, a plurality of first magnets on the top edge of the grinding disc, a rotating plate rotatably mounted on the left side of the top of the worktable, a second fixed frame on the top of the rotating plate, a first mounting plate and a second mounting plate symmetrically mounted on the top of the second fixed frame, and a second magnet at the bottom of both the first mounting plate and the second mounting plate.

[0005] Preferably, the middle of both the first mounting plate and the second mounting plate is set at a 45° angle.

[0006] Preferably, the first mounting plate is located between the second mounting plates, and the length of the second mounting plate is greater than that of the first mounting plate.

[0010] Preferably, the first fixing frame is provided with inclined guide plates symmetrically at the front and back, and the top of the workbench is provided with drainage grooves symmetrically at the front and back.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention requires no electric drive; with just one application of force, the grinding disc can be continuously rotated through magnetic interaction. It eliminates the need for electric devices and manual operation, reducing continuous human input and lowering labor costs.

[0013] The special layout and installation direction of the first and second magnets in this invention form a spatial magnetic field gradient. The 45° inclined installation extends the magnetic field action path, allowing the first magnet to quickly enter the next repulsive or attractive zone after leaving one repulsive zone, forming a continuous driving force, ensuring the stability and uniformity of the grinding disc rotation, thereby improving the grinding quality.

[0014] Compared with the dynamic grinding device, this utility model does not rely on motor drive, and there is no problem that the motor and circuit parts are prone to water ingress and short circuit, which reduces the risk of equipment damage and reduces maintenance costs and repair frequency.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] like Figures 1 to 4The optical mold edge grinding device shown includes a first fixed frame 2 on the top of a worktable 1, a grinding disc 3 rotatably mounted on the top of the first fixed frame 2, multiple suction cups 4 on the top of the grinding disc 3, and multiple first magnets 5 on the top edge of the grinding disc 3. A rotating plate 6 is rotatably mounted on the left side of the top of the worktable 1, and a second fixed frame 601 is mounted on the top of the rotating plate 6. A first mounting plate 7 and a second mounting plate 8 are symmetrically arranged on the front and back of the top of the second fixed frame 601. A second magnet 9 is provided at the bottom of both the first mounting plate 7 and the second mounting plate 8. The middle of the first mounting plate 7 and the second mounting plate 8 are both set at a 45° angle. The first mounting plate 7 is located between the second mounting plates 8, and the length of the second mounting plate 8 is greater than that of the first mounting plate 7. The number of second magnets 9 at the bottom of the first mounting plate 7 is 1, and the number of second magnets 9 at the bottom of the second mounting plate 8 is 2. The number of first magnets 5 is 2n. A central rod 10 is fixed on the fixed frame, and the grinding disc 3 is rotatably mounted on the top of the central rod 10 through a bearing 11. Inclined guide plates 12 are symmetrically arranged on the front and back of the first fixed frame 2, and drainage grooves 13 are symmetrically opened on the front and back of the top of the worktable 1.

[0023] This invention requires no electric drive; a single application of force is all it takes to achieve continuous rotation of the grinding disc 3 through magnetic interaction. It eliminates the need for electric devices and continuous manual rotation, reducing continuous labor input and lowering labor costs. The unique layout and installation orientation of the first magnet 5 and the second magnet 9 create a spatial magnetic field gradient. The 45° inclined installation extends the magnetic field path, allowing the first magnet 5 to quickly enter the next repulsive or attractive zone after leaving one, forming a continuous driving force. This ensures the stability and uniformity of the grinding disc 3's rotation, thereby improving grinding quality. Compared to moving grinding devices, this invention does not rely on a motor drive, eliminating the risk of water ingress and short circuits in the motor and electrical components, reducing the risk of equipment damage, maintenance costs, and repair frequency.

[0024] Example 2

[0025] An optical mold edge grinding device can trigger the continuous rotation of the optical mold in a short period of time with a single force application. It requires no electricity or manual operation to continuously drive the rotation, thus achieving dual savings in labor and electricity costs.

[0026] like Figures 1 to 4The optical mold edge grinding device shown includes a worktable 1, with a first fixing frame 2 on the top of the worktable 1. The first fixing frame 2 is open on the left side. A central rod 10 is fixed between the top and bottom of the first fixing frame 2. The central rod 10 passes through the top of the first fixing frame 2 and rotates to mount a grinding disc 3 via a bearing 11. When an optical mold is mounted on the top of the grinding disc 3, the bearing 11 reduces the frictional resistance during the rotation of the grinding disc 3, making the rotation of the optical mold smoother. The top of the grinding disc 3 is equipped with multiple suction cups 4 for mounting the optical mold. Considering that water or other liquids will be used to clean the grinding surface during grinding, the bottom of the optical mold can be moistened with water beforehand, and then the optical mold can be pressed between the tops of the suction cups 4 to achieve fixed mounting of the optical mold.

[0027] Furthermore, the top edge of the grinding disc 3 is provided with multiple first magnets 5. The first magnets 5 are strong magnets, and the number is 2n, that is, an even number symmetrically distributed, to ensure that they are symmetrically distributed on the grinding disc 3, so that the torque is balanced when the repulsive force and the attractive force alternate, and to avoid jamming.

[0028] Furthermore, the ratio of the magnet installation spacing to the diameter is 1.5:1, which ensures effective magnetic field coverage while avoiding direct cancellation between magnetic poles. During installation, the N pole faces upward and the S pole faces downward. Correspondingly, a rotating plate 6 is rotatably mounted on the top left side of the workbench 1. A second fixing frame 601 is mounted on the top of the rotating plate 6. A first mounting plate 7 and a second mounting plate 8 are symmetrically mounted on the top front and back of the second fixing frame 601. A second magnet 9 is mounted at the bottom of both the first mounting plate 7 and the second mounting plate 8. That is, the user can drive the rotating plate 6 to rotate the second magnet 9 on it. After the first magnet 5 and the second magnet 9 approach each other and interact, the user can adjust the position of the second magnet 9 on the second fixing frame 601 to control the first magnet 5 and the grinding wheel 3, thereby optimizing the magnetic force. Specifically, when it is necessary to rotate the grinding wheel 3, the second magnet 9 can be rotated to be close to the first magnet 5. After grinding is completed, if the grinding wheel 3 continues to rotate, rotating the second fixing frame 601 will move the second magnet 9 away from the first magnet 5, thereby gradually stopping the rotation of the grinding wheel 3.

[0029] The first mounting plate 7 is located between the second mounting plates 8, and the length of the second mounting plate 8 is greater than that of the first mounting plate 7. The number of second magnets 9 at the bottom of the first mounting plate 7 is 1, and the number of second magnets 9 at the bottom of the second mounting plate 8 is 2, that is, the second magnets 9 are generally arc-shaped. The middle of the first mounting plate 7 and the second mounting plate 8 are both set at a 45° angle. The second magnets 9 installed at the bottom are strong magnets, forming a spatial magnetic field gradient. The 45° tilt installation can also extend the magnetic field action path, so that the first magnet 5 can quickly enter the next repulsive or attractive force zone after leaving one repulsive force zone, forming a continuous driving force. The installation direction of the second magnet 9 is opposite to that of the first magnet 5, with the N pole facing down and the S pole facing up. The N pole of the second magnet 9 facing down and the N pole of the first magnet 5 facing up form a same-pole repulsion, while the S pole of the second magnet 9 facing up and the S pole of the first magnet 5 facing down form an opposite-pole attraction.

[0030] In practical applications, the user applies an initial external force manually, causing the grinding disc 3 to rotate slightly, triggering the magnetic field interaction between the second magnet 9 and the first magnet 5. The alternating action of magnetic repulsion and attraction converts magnetic energy into mechanical energy, driving the grinding disc 3 to rotate continuously. In a short period of time, no continuous external power input is required, reducing manpower consumption and realizing one-time edge grinding of optical molds.

[0031] Furthermore, during the grinding of the edges and corners of the optical mold, debris is generated. At the same time, clean water or other liquids are used to clean the grinding surface. The cleaned liquid falls downward onto the first fixed frame 2, washing away the debris. In addition, this embodiment also has inclined guide plates 12 symmetrically arranged in front and behind the first fixed frame 2. A water drainage groove 13 is opened on the top of the worktable 1 at the position outside the inclined guide plate 12. The liquid carrying the debris flows out through the inclined guide plates on both sides and then falls downward through the water drainage groove 13, avoiding interference with the work and maintaining environmental hygiene during the grinding process.
