Specifically, when the receiving and feeding mechanism moves the workpiece to a position between the first clamping piece and the second clamping piece, the first clamping piece is driven by the first transmission piece to move towards a direction close to the second clamping piece until the workpiece is clamped; similarly, when the grinding operation is completed and the material receiving and sending mechanism grabs the object, the first clamping piece moves towards the direction far away from the second clamping piece, so that the workpiece can be moved out of the clamping assembly.

The material receiving and feeding mechanism 30 is disposed between the grinding mechanism 10 and the feeding mechanism 20, and the material receiving and feeding mechanism 30 is used for transferring a workpiece (a silicon rod after the squaring operation is completed) on the feeding mechanism 20 to the grinding mechanism 10; in the present application, the grinding mechanism 10, the material receiving and feeding mechanism 30, and the material loading mechanism 20 are illustrated from left to right. The silicon rod before being cut is a cylinder, and the silicon rod after being cut is a cuboid, but the four surfaces are uneven and need to be ground by a grinding mechanism.

Referring to fig. 9, in the present embodiment, the feeding mechanism 20 includes: the feeding device comprises a feeding base 21, a sliding device 22, a third clamping piece 23, a fourth clamping piece 24, a third driving piece, a fourth driving piece, a second transmission piece and a positioning carrying platform 25; the sliding device 22 is arranged on the feeding base 21, and the second transmission piece can rotate around a rotating shaft of the second transmission piece and is arranged on the feeding base 21; the third clamping member 23 and the fourth clamping member 24 are slidably disposed on the sliding device 22, the positioning carrier 25 is disposed between the third clamping member 23 and the fourth clamping member 24, the third driving member is connected to the third clamping member 23, the fourth driving member is connected to the fourth clamping member 24, the third driving member is in transmission connection with the transmission member, and the fourth driving member is in transmission connection with the transmission member; the transmission member is used for driving the third clamping member 23 and the fourth clamping member 24 to synchronously move towards each other or synchronously move away from each other.

The sliding device 22 is fixedly disposed on the loading base 21, and the third clamping piece 23 and the fourth clamping piece 24 are slidably disposed on the sliding device 22. The second transmission parts can be rotatably arranged on the feeding base 21 around the rotating shafts of the second transmission parts, and only one second transmission part is arranged; the third clamping member 23 is in transmission connection with the second transmission member through the third driving member, and the fourth clamping member 24 is in transmission connection with the second transmission member through the fourth driving member; that is, the third clamping member 23 and the fourth clamping member 24 are synchronously moved by the transmission action of the second transmission member.

It should be noted that the sliding device 22 is a slide rail, and the third clamping member 23 and the fourth clamping member 24 are slidably disposed on the slide rail and slide along the slide rail; the two slide rails are parallel to each other, and the third clamping piece 23 and the fourth clamping piece 24 are arranged on the slide rails in a spanning mode; a notch is formed in the middle of one of the two sliding rails, a mechanical arm and other mechanisms can conveniently take and place workpieces, and the third clamping piece 23 and the fourth clamping piece 24 are arranged on two sides of the notch.

It should be further noted that, since the third clamping member 23 and the fourth clamping member 24 move synchronously, that is, when the third clamping member 23 and the fourth clamping member 24 move synchronously, the third clamping member 23 and the fourth clamping member 24 move by the same distance. Specifically, in practical use, when a workpiece is placed on the positioning stage 25, the workpiece cannot be accurately placed at the pick-and-place position due to factors such as errors, and at this time, the midpoint of the distance between the third clamping piece 23 and the fourth clamping piece 24 does not coincide with the workpiece midpoint; therefore, the third clamping member 23 and the fourth clamping member 24 are moved towards each other by driving the second transmission member, the third clamping member 23 or the fourth clamping member 24, and the third clamping member 23 or the fourth clamping member 24 pushes the workpiece to move towards the middle point of the distance between the third clamping member 23 and the fourth clamping member 24 until the workpiece is clamped by the third clamping member 23 and the fourth clamping member 24 (i.e. both ends of the workpiece are respectively contacted with the third clamping member 23 and the fourth clamping member 24), at which time, the middle point of the distance between the third clamping member 23 and the fourth clamping member 24 coincides with the middle point of the workpiece.

When the workpiece is placed in the pick-and-place position, the middle point of the workpiece coincides with the middle point of the distance between the third clamping piece 23 and the fourth clamping piece 24. The picking and placing positions are convenient for the receiving and feeding mechanism 30 in the grinding equipment to accurately pick up the workpiece, and particularly, when the receiving and feeding mechanism 30 picks up the workpiece, the middle point of the claw clamp in the receiving and feeding mechanism 30 coincides with the middle point of the workpiece. The synchronous relative movement means that when the third clamping member 23 performs a plurality of distances toward the fourth clamping member 24, the fourth clamping member 24 also performs a plurality of distances toward the third clamping member 23; otherwise, synchronous phase deviation motion is performed.

In a similar way, the second material receiving and feeding sliding mechanism comprises: the clamping device comprises a first receiving and feeding sliding rail and a first receiving and feeding sliding block, wherein the first receiving and feeding sliding block is arranged on the first receiving and feeding sliding rail in a sliding mode; the second material receiving and feeding slide rail is arranged on the side wall of the material receiving and feeding rack and is vertical to the first material receiving and feeding slide rail, so that the second material receiving and feeding slide block moves in the vertical direction along the second material receiving and feeding slide rail; namely, the motion track of the second material receiving and feeding slide block is perpendicular to the motion track of the first material receiving and feeding slide block, and the clamping device rotates in the vertical direction. According to the steps, the workpiece in the horizontal state can be indexed to 90 degrees, so that the workpiece is in the vertical state. The material receiving and feeding frame and the clamping device can complete rotating operation under the driving of a rotating motor. The workpiece in the present application is a rod-shaped workpiece, such as a single crystal silicon rod.

The clamping device is used for clamping the workpiece which is subjected to centering operation; specifically, when a workpiece is placed on the feeding mechanism 20, the first clamping member 121 and the second clamping member 122 are moved towards each other (i.e., towards the workpiece) by driving the third transmission member 35, the fifth clamping member 36 or the sixth clamping member 37; when the workpiece is moved to the grinding mechanism 10, the fifth clamping piece 36 and the sixth clamping piece 37 move away from each other, so that the distance between the fifth clamping piece 36 and the sixth clamping piece 37 is increased, and the next workpiece is clamped conveniently. Specifically, the fifth driving element 33 is connected to the sixth driving element 34 and is connected to the third transmission element 35, and the third transmission element 35 makes the two synchronously and reversely move. In this application, a synchronous relative movement means that, when the fifth gripper 36 makes several distances towards the sixth gripper 37, the sixth gripper 37 will also make several distances towards the fifth gripper 36; otherwise, synchronous phase deviation motion is performed.

It should be further noted that two sets of third material receiving and feeding slide rails are arranged on two sides of the sliding assembly 31, the two sets of third material receiving and feeding slide rails are oppositely arranged on two sides of the sliding assembly 31, and the fifth clamping member 36 and the sixth clamping member 37 are both slidably connected to the two sets of third material receiving and feeding slide rails.

It should be further explained that, in the prior art, a workpiece is generally adjusted to a correct position first and then is clamped, however, a clamping driving mode is generally realized by a gear rack or a bidirectional screw mechanism, and the two mechanisms have meshing gaps, so that clamping accuracy is poor and subsequent grinding accuracy is affected. Thus, in the present application, two third power sources 32 are provided, and the output ends of the two third power sources 32 are connected to the fifth driving member 33 and the sixth driving member 34, respectively, and of course, in some embodiments, the output ends of the two third power sources 32 are connected to the fifth clamping member 36 and the sixth clamping member 37, respectively; the two third power sources 32 are arranged side by side, and the force application directions of the two third power sources 32 are opposite, that is, one of the third power sources pushes downwards, and the other one pulls upwards. The arrangement of the two third power sources 32 can reduce the meshing clearance of the fifth driving element 33, the sixth driving element 34 and the third transmission element 35, and improve the clamping force of the fifth clamping element 36 and the sixth clamping element 37. Both of the third power sources 32 may be motors or cylinders. Even if the forces of pushing by the two third power sources 32 are different, the distance traveled by the fifth clamping member 36 and the sixth clamping member 37 is the same under the action of the third transmission member 35; specifically, the third transmission member 35 limits the third power source 32 having a large thrust together with the third power source 32 having a small thrust, and similarly, the third transmission member 35 assists the third power source 32 having a small thrust together with the third power source 32 having a large thrust. Of course, if the engagement gap is too large, the two third power sources 32 can output the same force at the same time, and thus the error caused by the gap can be eliminated. Under the locking force effect of cylinder, the gear rack's meshing clearance is eliminated, consequently has more stable centre gripping effect.

In practical use, the first sliding block drives the material receiving and feeding frame to move towards the direction of the feeding mechanism 20, and after the material receiving and feeding frame moves to one side of the feeding mechanism 20, the material receiving and feeding frame rotates to enable the clamping device to face the feeding mechanism 20; the second slide block drives the clamping device to move on the second slide rail, so that a gap between the fifth clamping piece 36 and the sixth clamping piece 37 is flush with the workpiece; the first sliding block drives the material receiving and feeding frame to move towards the direction of the feeding mechanism 20 again, so that the workpiece is placed between the fifth clamping piece 36 and the sixth clamping piece 37; the third power source 32 drives the fifth clamping member 36 and the sixth clamping member 37 to move towards each other so as to clamp the workpiece. Then, the material receiving and feeding frame rotates to enable the clamping device to face the grinding mechanism 10; the clamping device rotates the workpiece by 90 degrees, the workpiece is moved to a proper height through the second sliding block, and finally the first sliding block drives the material receiving and feeding frame to move towards the grinding mechanism 10, so that the workpiece is fed into the grinding mechanism 10 to be ground.
