Description

Technical Field

[0002] Before the grinder is ready for processing, the robot arm needs to hold up the single crystal silicon rod and place it into the grinder. The clamp head needs to tighten the single crystal silicon rod before processing can be carried out. Before processing, the horizontal up and down position of the single crystal silicon rod needs to be adjusted. Each adjustment requires the single crystal silicon rod to be placed back on the robot arm, and the robot arm is used to adjust the horizontal up and down position of the single crystal silicon rod. The adjustment speed is slow. After the adjustment is completed, the single crystal silicon rod needs to be placed inside the grinder and the measuring probe is used to perform pre-grinding inspection on the single crystal silicon rod. If there is a deviation in the horizontal up and down position adjustment of the single crystal silicon rod, the previous operation needs to be repeated.

[0029] This embodiment provides a grinding clamping workbench, which can adjust the horizontal and vertical positions of the silicon rods to achieve the adjustment of the silicon rod axis, such as Figure 1As shown, it includes a clamp head 1, a left-right adjustment mechanism, and an up-down adjustment mechanism. The two clamp heads 1 are suitable for moving back and forth in opposite directions to tighten or loosen the two ends of the silicon rod; the movable ends of the two left-right adjustment mechanisms are respectively connected to the two clamp heads 1, and the two left-right adjustment mechanisms are used to adjust the left-right offset position of the silicon rod, thereby adjusting the axis of the silicon rod; the movable ends of the two up-down adjustment mechanisms are respectively connected to the fixed ends of the two left-right adjustment mechanisms, and the two up-down adjustment mechanisms are used to adjust the up-down offset position of the silicon rod to keep the axis of the silicon rod in a horizontal state. The clamp head 1 in this embodiment has the same structure as the clamp head 1 of the existing grinding device, and its specific structure will not be repeated here.

[0030] Optionally, the vertical adjustment mechanism includes a first lead screw 2, a first motor 3, and a lifting platform 4. The first lead screw 2 is vertically mounted via a lead screw support column 5. The first motor 3 is used to drive the first lead screw 2 in rotation. The lifting platform 4 is threadedly connected to the first lead screw 2 and is used to mount the left-right adjustment mechanism. The first motor 3 can be connected to the first lead screw 2 via a speed reducer and mounted outside the lead screw support column 5. The first motor 3 drives the first lead screw 2 in rotation, which in turn drives the lifting platform 4 up and down, thereby adjusting the vertical position of the corresponding end of the silicon ingot.

[0031] Optionally, the left-right adjustment mechanism includes a worktable 6, a second lead screw 7, a second motor 8, and a left-right movable plate 9. The worktable 6 is mounted on the lifting platform 4 and rises and falls with the lifting platform 4. The second lead screw 7 is mounted on the worktable 6 in a left-right direction. The second motor 8 is used to drive the second lead screw 7 to rotate. The left-right movable plate 9 is threadedly connected to the second lead screw 7. The left-right movable plate 9 extends out of the worktable 6 toward the clamp head 1, and the extended end of the left-right movable plate 9 is connected to the clamp head 1. The two left-right adjustment mechanisms respectively adjust the left-right position of the two ends of the silicon ingot, thereby adjusting the silicon ingot axis.

[0032] In this embodiment, both the up-down adjustment mechanism and the left-right adjustment mechanism adopt a screw mechanism, which is quick and stable to use and has high precision.

[0033] Optionally, this embodiment further includes a forward and backward moving mechanism, the moving end of which is connected to the fixed end of the up and down adjustment mechanism, and the forward and backward moving mechanism is used to drive the clamp head 1 to move forward and backward in reverse. The screw support column 5 and the first motor 3 are arranged on the moving end of the forward and backward moving mechanism. The forward and backward moving mechanism belongs to the existing structure in the grinding device, which can be two linear modules, cylinders, hydraulic cylinders, etc. to drive the corresponding clamp heads 1 to move forward and backward, and guide rails can be set corresponding to their movement. The two clamp heads 1 move in opposite directions to tighten or loosen the silicon rod; or the forward and backward moving mechanism is a double-screw mechanism with opposite rotation directions, and the rotation of the screw can also drive the two clamp heads 1 to move in reverse. The up and down adjustment mechanism, the left and right adjustment mechanism and the clamp head 1 move forward and backward and reverse together with the forward and backward moving mechanism.

[0034] This embodiment also provides a grinding device, comprising the aforementioned grinding clamping table, a measuring probe, and a controller. The measuring probe is used to perform pre-grinding inspection on the silicon rod clamped by the clamp head 1. The controller determines horizontal and vertical offset differences based on the measured values ​​of the measuring probe. The left-right adjustment mechanism and the vertical adjustment mechanism adjust the horizontal and vertical positions of the silicon rod based on the offset differences. The measuring probe has the same structure as the measuring probe of existing grinding devices, and the controller determines the horizontal and vertical offset differences based on the measured values ​​of the measuring probe, which is also conventional.

[0035] The working process of this embodiment: the grinding device is equipped with two screw devices, namely the left and right adjustment mechanism and the up and down adjustment mechanism, at the worktables of the front and rear clamp heads respectively. The second screw 7 controls the left and right offset of the single crystal silicon rod, and the first screw 2 below the worktable 6 controls the up and down offset of the single crystal silicon rod. After the grinding device is loaded by the truss manipulator, the measuring probe measures the single crystal silicon rod. According to the pre-grinding inspection, the controller calculates the horizontal and upper and lower point offset differences of the measured values. The left and right adjustment mechanism and the up and down adjustment mechanism adjust the horizontal and upper and lower positions of the single crystal silicon rod according to the offset difference. After the adjustment is completed, the pre-grinding inspection is carried out again. The processing can only start after the inspection is qualified.

[0036] In summary, this embodiment adjusts the horizontal and vertical offset positions of the silicon rod inside the grinding device, which can save the time of telescopic movement of the robot arm. The use of the screw mechanism is fast, stable, and has high precision. This embodiment can effectively reduce the number of secondary clamping times, increase the working efficiency of the grinding device, and improve the processing capacity of the equipment.
