Especially in the production sites with small production scale and not very large production volume, in the existing technology, the grinding of optical glass is generally done by the staff holding an electric grinding device (with a motor and a grinding head) to grind the corresponding surface of the optical glass fixed by a fixing mechanism.
[0003] Although the manual use of electric grinding equipment for optical glass grinding has met the actual production needs to a certain extent, it requires manual operation by the staff, which will bring inconvenience to the staff and is not conducive to improving work efficiency. In addition, if the staff does not clean up the glass dust generated during grinding and it falls on the grinding table in time, the amount of dust floating into the air will be too large, which will have an adverse effect on the respiratory health of the staff. In summary, it is particularly necessary to provide a grinding device that can improve work efficiency and reduce adverse effects on the health of the staff. Utility Model Content
[0004] In order to overcome the drawbacks mentioned in the background in the existing optical glass surface grinding due to the lack of a practical device, the present invention provides a new optical glass grinding device which, under the joint action of relevant mechanisms, allows the staff to control the grinding head to rotate up or down, clockwise or counterclockwise to grind the optical glass surface by simply operating a power switch. The dust generated during grinding will fall into the water tank and be absorbed by the water, which correspondingly improves the work efficiency, brings convenience to the staff, and minimizes the adverse effects of dust after grinding on the health of the staff.

Water is added to the hollow part of the bottom plate 1 through the dust inlet hole.
[0016] Figure 1 , 2As shown in , the reed switches T1 and T2 are normally closed contact reed switches, the moving contacts of the reed switches T1 and T2 are located at the inner end and the moving contacts of the two reed switches T1 and T2 are in a face-to-face structure, and the magnet 6 and the reed switches T1 and T2 are in the same plane. A branch pipe that is interconnected with the inside is welded in the middle of the right end of the bottom plate 1, and the outer end of the branch pipe is connected to one end of the valve 8 through a thread, and the other end of the valve 8 is connected to the wastewater tank through a pipeline. The time control circuit includes two sets of time relay modules W2 and W3 connected by wires, and the power input ends 1 and 2 of the two sets of time relay modules W2 and W3 are connected respectively. One of the power output ends 3 and 4 of the two sets of time relay modules W2 and W3 is connected to one end of the two reed switches T1 and T2 through a wire, and the other end of the two reed switches W2 and W3 is connected to one of the power input ends of the electric linear slide M3 through a wire.
[0017] Figure 1 , 2 As shown in the figure, the electric grinder body M2 is connected in series through a power switch D3, the power input terminals 1 and 2 of the power module W1 are connected to the two poles of the AC 220V power supply through wires, the power output terminals 3 and 4 of the power module W1 and the three power switches D (1 and 2), D1 (1 and 2), the power input terminals of D2, the power input terminals of the two sets of time relay modules W2 and W3 of the timing circuit are connected through wires, the power output terminals 3, 4 and 5, 6 of the power switches D1 and D are connected to the positive and negative and negative and positive power input terminals of the electric push rod M1 and the motor reduction mechanism M through wires, and the power output terminals of the two sets of time relay modules W2 and W3 of the timing circuit are connected to the positive and negative or negative and positive power input terminals of the electric linear slide M3 through wires. All power switch handles are located outside the four openings at the front end of the component box 7.
[0018] Figure 1 , 2As shown, before the new grinding, the optical glass can be ground after being fixed by a fixing mechanism (the fixing mechanism is a mature device, and the fixing mechanism is installed in the middle of the upper part of the bottom plate). After the AC 220V power supply enters the power input terminal of the power module W1, its 3rd and 4th pins output a stable DC 24V power supply to enter the power input terminal of the power switch D, D1 and the time control circuit (the time control circuit will be powered on only when the power switch D2 is turned on). In the specific grinding, when the staff turns the handle of the power switch D1 to the left or right, the 1st and 2nd pins and the 3rd and 4th pins or the 5th and 6th pins of the power switch D1 are connected respectively, so that the positive and negative or negative and positive power input terminals of the electric push rod M1 will be powered, and the movable column of the electric push rod M1 will drive the electric grinder body M2 up or down (the linear bearing is the up or down guide of the electric grinder body M2) to contact the surface of the optical glass that needs to be ground for grinding (turn off the power switch after it is in place). When the staff turns the handle of the power switch D to the left or right, the 1, 2 pins and the 3, 4 pins or the 5, 6 pins of the power switch D are connected respectively, so that the positive and negative or negative and positive power input terminals of the motor reduction mechanism M will be energized, and the rotating shaft of the motor reduction mechanism M will drive the electric grinder body M2 to rotate clockwise or counterclockwise to contact the surface of the optical glass to be ground for grinding (turn off the power switch after it is in place). After the power switch D3 is turned on, the electric grinder body M2 is energized to work and grind the surface of the optical glass through the grinding head.After the two sets of time relay modules W2 and W3 are energized, their 3rd and 4th feet will cyclically output for a period of time (for example, the time relay module W2 first outputs power for 10 seconds, and then W3 outputs power for 10 seconds, and the specific time is adjustable) the positive and negative and negative and positive and negative power input ends, and enter the power input end of the electric linear slide M3; during the time when the positive and negative power supplies of the electric linear slide M3 are energized, its sliding block drives the electric grinder body M2 to grind the optical glass surface from left to right; during the time when the negative and positive power supplies of the electric linear slide M3 are energized, its sliding block drives the electric grinder body M2 to grind the optical glass surface from right to left; during grinding, when the sliding block of the electric linear slide M3 drives the electric grinder body M2 to move to the left or right to the stop point, the two magnets 6 will approach the left end reed switch T1 or T2 respectively, so that the reed switch T1 or T2 is subjected to the corresponding magnetic force of the corresponding magnet 6 and its internal contacts Open circuit, in this way, since pin 3 of the time relay module W2 is connected to the positive power input terminal of the electric linear slide M3, and pin 3 of the time relay module W3 is connected to the negative power input terminal of the electric linear slide M3, after the sliding block of the electric linear slide M3 drives the electric grinder body M2 to move left or right to the stop point, the electric linear slide M3 will lose power and stop working (without hindering the reverse input of power to the power input terminal of the electric linear slide), preventing the electric linear slide M3 from driving the electric grinder body to move left or right without control, resulting in abnormal operation (before actual grinding, the staff glues the corresponding positions of the two reed switches, so that the electric linear slide M3 drives the electric grinder body M2 to move left and right, right and left, which is just in the horizontal dynamic movement to the two sides of the grinding optical glass surface. If this function is not selected and the power switch D2 is turned off, the electric grinder body can grind the optical glass at a fixed point). During grinding, particles and dust generated by grinding enter the bottom plate 1 through multiple dust inlet holes 101, and the water in the bottom plate 1 absorbs the dust and particles (opening the valve 8 later can release wastewater containing more impurities, and then add water to the bottom plate). Through the action of all the above-mentioned mechanisms, the staff of this new type only needs to operate the power switch simply to control the electric push rod to move the electric grinder body up or down to the grinding station, and control the electric grinder body to rotate clockwise or counterclockwise to the grinding station to grind the surface of the optical prism through the motor reduction mechanism, which correspondingly improves work efficiency and brings convenience to the staff; because there are multiple dust inlet holes in the middle of the upper end of the bottom plate, the dust generated during grinding falls back into the water tank and is absorbed by the water, which correspondingly minimizes the adverse effects of dust after grinding on the health of the staff.The power module W1 is a finished product of a 220V AC to 24V DC switching power module; the electric grinder body M2 is an electric grinder body with a working voltage of 220V DC and a power of 2.5KW; the electric push rod M1 is a finished product of a reciprocating electric telescopic rod; the electric linear slide M3 is a finished product of a lead screw electric linear slide with a power of 500W; the reed switches T1 and T2 are glass shell normally closed contact reed switches; the motor reduction mechanism M is a finished product of a coaxial motor gear reducer with a power of 1KW and a voltage of 24V; the time relay modules W2 and W3 are finished products of a microcomputer time-controlled switch of model KG316, which has two power input terminals, two power output terminals, and seven Only buttons are set, and by operating multiple buttons separately, the power output time of the two power output terminals can be set (the time relay modules W2 and W3 set the corresponding output time, and can set the electric linear slide M3 to drive the electric grinder body M2 to move left or right to a suitable position. Because the time relay modules W2 and W3 control the electric linear slide M3 to drive the electric grinder body M2 to move left or right to a suitable position, it is not intuitive, so for inexperienced staff, the positions of the two reed switches can be set according to the horizontal length of the optical glass, and then the electric linear slide M3 can be controlled to drive the electric grinder body M2 to move left or right to a suitable position, which is more flexible in application).
