Description

Technical Field

[0002] Some crystals, such as KDP crystals, have irregular shapes when they are grown, and have low hardness and high brittleness. However, the application scenarios of KDP crystals require them to be processed into cylindrical shapes. For the above reasons, the crystals need to be rounded.

[0062] The utility model provides a crystal grinding device, which is used for grinding irregularly shaped crystals into regular shaped cylinders. The structure of the crystal grinding device is specifically described as follows.

[0063] Structural reference of base 1 Figure 1 As a supporting structure of the entire crystal grinding device, in this embodiment, the base 1 is L-shaped, including a first base arm 101 and a second base arm 102 arranged at right angles. The structure of the base 1 is not limited, and can also be designed into other shapes as needed. A support table 103 is arranged on the end surface of the base 1. The support table 103 is in the shape of a plate and is installed at the corner where the first base arm 101 and the second base arm 102 intersect.

[0064] A first guide rail 201 and a second guide rail 202 are disposed on the upper end surface of the base 1 , and the first guide rail 201 and the second guide rail 202 are disposed vertically; in this embodiment, the first guide rail 201 is disposed on the first base arm 101 , and the second guide rail 202 is disposed on the second base arm 102 .

[0065] The first guide rail 201 and the second guide rail 202 have the same structure, and their sizes are designed according to requirements. Figure 2a and Figure 2b , the structure of the two guide rails is described by taking the structure of the first guide rail 201 as an example, including a guide rail plate 2011, and a track 2022 arranged on the guide rail plate 2011. In order to ensure the stability of sliding, two tracks 2022 are arranged in parallel, and a mounting plate 2023 is arranged at the bottom of the guide rail plate 2011. The mounting plate 2023 is provided with bolt holes 2014, which are used to fit the side wall of the first base arm 101 and be mounted on the first base arm 101. The structure of the second guide rail 202 is the same as that of the first guide rail 201, and will not be repeated.

[0066] The support structure further includes a first slide 301 and a second slide 302: the first slide 301 is mounted on the first guide rail 201 and can slide along the first guide rail 201, and the second slide 302 is mounted on the second guide rail 202 and can slide along the second guide rail 202; the first guide rail 201 and the second guide rail 202 face different sides of the support platform 103, and the first slide 301 and the second slide 302 can both move toward or away from the support platform 103. Since the positions of the first guide rail 201 and the second guide rail 202 are relatively vertical, the relative movement directions of the first slide 301 and the second slide 302 are vertical.

[0067] Specifically, a slider 5 is installed at the bottom of each slide, and the slider 5 is installed on the track 2022. Since there are two tracks 2022, two groups of sliders 5 are correspondingly arranged at intervals on both sides of the bottom of the guide plate 2011, and the number of sliders 5 in each group can be one or more.

[0068] In order to drive the first slide 301 and the second slide 302 to move, a motion driving structure is further designed, including:

[0069] The first lead screw 701 and the first motor 501, the power output end of the first motor 501 is connected to the first lead screw 701, and the first slide 301 is connected to the first lead screw 701 via the first lead screw slider.

[0070] The second lead screw 702 and the second motor 502, the power output end of the second motor 502 is connected to the second lead screw 702, and the second slide 302 is connected to the second lead screw 702 via the second lead screw slider.

[0071] That is, the outer ends of the two lead screw linear guide platforms are connected to a servo motor, and the servo motor is provided with a power cord interface and a CN3 interface, and the CN3 interface can be connected to an external controller to realize the control of the servo motor.

[0072] Starting the first motor 501 and the second motor 502 can drive the first slide 301 and the second slide 302 to move along the first lead screw 701 and the second lead screw 702 respectively.

[0073] During the crystal grinding process, the crystal needs to be stably clamped. In this embodiment, the problem of crystal clamping is solved by using a first end crystal clamping device and a second end crystal clamping device in pairs.

[0074] The first end crystal clamping device is arranged on the first slide 301, and is used to clamp the crystal 5 to be processed. Figure 3, including a first bracket 601, a transverse through hole 602 is arranged on the first bracket 601, and a mounting hole 603 is arranged on the end surface of the first bracket and passes through the height direction of the first bracket, which is used to mount the first bracket 601 to the first slide 301:

[0075] Clamping drive motor 8: mounted on the first bracket 601;

[0076] The first end fixed end head 9 is detachably mounted on the power output end of the clamping drive motor 8 ; the fixed end head 9 is arranged toward the direction of the support platform 103 .

[0077] The second end crystal clamping device is installed on the support platform 103, located on a side of the support platform 103 opposite to the first slide platform 301, and opposite to the first end crystal clamping device.

[0078] When the first crystal clamping device moves along with the first slide table 301 toward the direction close to the second crystal clamping device, the two cooperate to clamp the crystal.

[0079] In some embodiments of the utility model, the second end crystal clamping device includes a fixed block 10 mounted on a support table 103, and a second end fixed terminal 11 detachably mounted on the fixed block 10. The second end fixed terminal 11 is a polyurethane terminal, and the size can be selected according to needs, the small diameter is solid and the size is unchanged, and the large diameter is hollow. Polyurethane terminals of different models and specifications can be customized according to the diameter of the rounded crystal.

[0080] In some embodiments of the present invention, a positioning groove 104 is formed on the support platform 103 , and the fixing block 10 is installed in the positioning groove 104 .

[0081] In some embodiments of the present invention, a pressure sensor is disposed on the first-end fixed end 9 to detect the clamping pressure between the first-end crystal clamping device and the second-end crystal clamping device.

[0082] The crystal grinding work is completed by the grinding wheel 12, and the grinding wheel 12 is mounted on the second slide 302 via the second bracket 13;

[0083] The grinding wheel 12 is driven by an electric spindle 14 , and a power output end of the electric spindle 14 is connected to the grinding wheel 12 to drive the grinding wheel 12 to rotate.

[0084] The structure of the second bracket 13 is shown in FIG. Figure 7 , including a mounting plate 1301, a second bracket body 1302, and the second bracket body 1302 and the mounting plate 1301 are an integrated structure. A mounting hole 1303 is provided on the second bracket body 1302. The second bracket 13 is mounted on the second slide 302 through the mounting plate 1301, and the electric spindle 14 is mounted in the mounting hole 1303.

[0085] In order to collect crystal debris during the grinding process, some embodiments of the present invention further include a debris collection slot 15, which is arranged at the corner of the first base arm 101 and the second base arm 103, located inside the corner, close to the grinding wheel 12. The debris collection slot 15 is directly connected to the support base 1 through 3M glue, and is connected to the fan duct outside, and the end is connected to the fan. The dust and debris generated during the rolling process are swept to the vicinity of the debris collection port by the operator with a brush, and the debris and dust are naturally sucked into the duct and discharged along the duct.

[0086] In order to assist in fixing the crystal to be processed, some embodiments of the present invention further include an auxiliary fixing block 16, which can be assembled with the crystal to be processed 17 and can be assembled with the first end fixing end 9 or the second end fixing end 11.

[0087] The working principle of the crystal grinding equipment provided by the utility model is as follows.

[0088] Select the prismatic crystal 17 that needs to be rounded, and according to the size of the rounding, select a pair of auxiliary fixing blocks 16 with the same diameter as the rounding size, heat the three, apply hot melt adhesive on the two bottom surfaces of the prismatic crystal 17, and buckle the two auxiliary fixing blocks 16 on the two bottom surfaces of the prismatic crystal 17 respectively to ensure that the two auxiliary fixing blocks 16 are aligned, and let stand to cool and solidify.

[0089] Hold the combination of the prismatic crystal 17 and the auxiliary fixing block 16, insert the auxiliary fixing block 16 into the second end fixing terminal 11 on the fixing block 10, and gently hold the crystal 17 with your hand to keep it level.

[0090] Turn on the power supply, control the first lead screw 701 to rotate, the first slide 301 moves to the side close to the support platform 103, and the first end crystal clamping device approaches the second end crystal clamping device. When the other end of the combination of the prismatic crystal 17 and the cylindrical block 504 hits the first fixed end 9 of the first motor 401, release the hand holding the crystal, and the first lead screw 701 of the X axis is still moving. This process is the process of gradually fixing and clamping the upper and lower bottom surfaces of the crystal. When the first fixed end 9 with a pressure sensor detects that the pressure value reaches the preset value, the power to the first motor 401 of the X axis is turned off.

[0091] When rolling, the electric spindles of the X-axis and Y-axis rotate in opposite directions.

[0092] The second lead screw 702 of the Y-axis screw rod rotates, driving the second slide 302 to move in the direction close to the crystal 9, and the feed amount of the second slide 302 is obtained by calculation. First, when the second slide 302 of the Y-axis returns to the origin, the distance between the grinding wheel 12 and the first fixed end 9 and the second fixed end 11 is set to L, the diameter of the prismatic crystal 17 when rounding is completed is set to d, and the diameter of the grinding wheel 12 is set to D. Then, we can easily deduce that the second lead screw 702 of the Y-axis controls the feed distance (LDd) of the second slide 302 from the origin to complete the rounding size.

[0093] Due to the requirement for the surface roughness of the rounded crystal, the sanding wheel 12 needs to be replaced once during the rounding process. During the rough rounding, we use a 600-mesh sanding wheel 12, and the second motor 402 controls the second slide 302 to feed forward a distance of (LD-d+1), and then return to the origin. After that, the 2000-mesh sanding wheel 12 is replaced, and the driver drives the second motor 402 of the Y axis to control the second slide 30 of the Y axis screw to feed forward a distance of (LDd), and the rounding of the prismatic crystal 17 is completed.

[0094] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
