Description

Technical Field

[0001] This utility model relates to the field of crystal rod edge processing technology, and in particular to a crystal rod edge clamping device. Background Technology

[0002] Currently, our company uses the Nissin vertical squaring machine for crystal ingot squaring. After the crystal ingot is squared, four edge pieces are produced. The vertical squaring machine uses an independent control method to clamp the four edge pieces. That is, four cylinders drive the lever mechanism to clamp the edge pieces. When the cylinders retract, the lever mechanism extends the pressure block outward and presses down on the edge pieces. Finally, the edge clamping mechanism is moved upward as a whole to achieve the clamping and transfer of the edge pieces.

[0003] In the existing technology, the edge-clamping mechanism has a small contact area between the pressure block and the edge due to structural problems, and the overall force direction of the edge is downward, which often causes the edge to fall off during the clamping process. Utility Model Content

[0004] This invention addresses the problem in existing edge-clamping mechanisms where the contact area between the clamping block and the edge skin is too narrow, and the edge skin is subjected to downward force, causing it to fall off during the clamping process. It provides a crystal rod edge-clamping device.

[0005] The technical solution adopted in this utility model is:

[0006] A device for gripping crystal rod edge skin includes: a frame and a clamping mechanism installed inside the frame, the clamping mechanism being used to clamp the crystal rod edge skin;

[0007] The clamping mechanism specifically includes:

[0008] Base frame assembly;

[0009] The cylinder is mounted on the base frame assembly;

[0010] A bracket is fitted onto the telescopic end of the cylinder;

[0011] At least one execution component;

[0012] Any of the execution components includes:

[0013] Pressed blocks;

[0014] The first connecting rod is rotatably connected to the pressure block at one end;

[0015] The second connecting rod is rotatably connected at one end to the pressure block and is located on the same side as the first connecting rod;

[0016] The first connecting rod is rotatably connected to the base frame assembly at the end away from the pressure block, and the second connecting rod is rotatably connected to the bracket at the end away from the pressure block. The second connecting rod is located below the first connecting rod.

[0017] Furthermore, the base frame assembly includes:

[0018] The base plate is connected to the cylinder on one side and to the frame on the other side;

[0019] Several upright plates are arranged in a circular array at the bottom of the base plate and extend toward the telescopic end of the cylinder.

[0020] Furthermore, a connecting seat is formed on the outer side of the upright plate, and the end of the first connecting rod away from the pressure block is rotatably connected to the connecting seat.

[0021] Furthermore, the bracket has a number of forks evenly distributed around its circumference, the same as the number of upright plates, and the end of the second connecting rod away from the pressure block is rotatably connected to the forks.

[0022] Furthermore, the execution component also includes:

[0023] A pressure block seat is installed on one side of the pressure block, and the first connecting rod and / or the second connecting rod are rotatably connected to the pressure block seat.

[0024] Furthermore, a first connecting rod seat and a second connecting rod seat are formed on the side of the pressure block seat facing the bracket;

[0025] The first connecting rod seat is located above the second connecting rod seat, and the first connecting rod seat is arranged along the width direction of the pressure block seat;

[0026] The first connecting rod seat is rotatably connected to the first connecting rod, and the second connecting rod seat is rotatably connected to the second connecting rod.

[0027] Furthermore, the rack includes:

[0028] The support frame has columns formed around its lower perimeter.

[0029] Connect the top plate, which is installed on the top of the support frame;

[0030] The connecting base plate is installed at the bottom of the column;

[0031] The base frame assembly is disposed inside the support frame and installed below the connecting top plate.

[0032] Furthermore, the rack also includes:

[0038] The beneficial effects of this utility model are:

[0039] The clamping mechanism is installed inside the support frame, and the enclosure is fitted onto the support frame. The inner sidewall of the enclosure fits against the outer arc-shaped surface of the edge skin. When the cylinder in the clamping mechanism extends, it drives the support to move downward. One end of the second connecting rod connected to the shift fork moves downward with the support, while the other end of the second connecting rod swings about the second connecting rod seat as an axis, pushing the pressure block seat away from the cylinder. The pressure block seat moves upward as it moves outward, causing the first connecting rod to rotate upward about the connecting seat as an axis. The pressure block, in conjunction with the enclosure, gradually clamps the crystal rod edge skin. Then, a robotic arm removes the edge skin. During the movement of the pressure block, its outer plane remains parallel to the inner plane of the edge skin, ensuring that the force exerted by the pressure block on the edge skin is always perpendicular to the inner plane of the edge skin, thus preventing the edge skin from falling off during the clamping process.

[0055] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0056] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0057] This embodiment provides a device for gripping the edge of a crystal ingot, which solves the problem in existing edge-gripping mechanisms where the contact area between the clamping block and the edge is narrow, and the edge is subjected to downward force, causing it to fall off during gripping. The goal is to ensure the edge does not fall off during gripping after the crystal ingot has been squared, thereby improving work efficiency. See also... Figure 1 It can be seen that the crystal rod edge clamping device 100 mainly includes a frame 200 and a clamping mechanism 300. The frame 200 is used to support the clamping mechanism 300. The top of the frame 200 is connected to the robotic arm. The entire device can be moved by the robotic arm. After the clamping mechanism 300 clamps the crystal rod edge, the crystal rod edge is taken out by the action of the robotic arm.

[0058] Combination Figure 2 and Figure 3 As can be seen, the frame 200 mainly consists of a connecting top plate 201, a support frame 202, a cover 203, a enclosure 204, and a connecting bottom plate 205. The connecting top plate 201 is a square flat plate with a circular through hole in the center and top plate through holes 2011 machined at the corners. Threaded holes are machined at corresponding positions on the top of the support frame 202. The connecting top plate 201 is fixed to the top of the support frame 202 with bolts. The upper and lower ends of the support frame 202 are open, with a square cross-section. Four columns 2022 are formed around the lower end, and the space between the four columns 2022 is the movement space of the clamping mechanism 300. Threaded holes are machined at the ends of the columns 2022. The connecting bottom plate 205 has corresponding through holes, and thus the connecting bottom plate 205 is connected to the bottom of the support frame 202 with bolts.

[0059] Figure 4 This is a schematic diagram of the combined structure of the cover 203 and the enclosure 204. The main body of the cover 203 is disc-shaped, with several through holes 2032 arranged in a ring around its edge. Correspondingly, threaded holes are machined at the top of the enclosure 204. The cover 203 is fixed to the top of the enclosure 204 with bolts. The enclosure 204 is cylindrical, hollow inside, and has a through hole at the center of its top. A square connecting flange 2031 is formed at the center of the side of the cover 203 away from the enclosure 204. The connecting flange 2031 is hollow inside, facilitating its installation on the support frame 202. Three through holes are machined on one side wall of the connecting flange 2031, and similar through holes of the same diameter are machined at the same positions on the other three side walls. See also... Figure 2 and Figure 3 It can be seen that the support frame 202 has a support frame threaded hole 2021 on its side, which corresponds to the position of the through hole on the connecting flange 2031. The cover 203 is sleeved on the support frame 202 and fixed by bolts, so that the enclosure 204 is also sleeved on the support frame 202.

[0060] Figure 5 This is a schematic diagram of the clamping mechanism 300 in the edge leather gripping device. The clamping mechanism 300 mainly includes a base frame assembly 301, a cylinder 302, an actuation assembly 303, and a bracket 304. Figure 7 It can be seen that the base frame assembly 301 includes a base plate 3011, a circular through hole is provided in the center of the base plate 3011, four base plate through holes 3013 are arranged in a ring around the circular through hole, four base plate threaded holes 3012 are machined at the four corners of the base plate 3011 away from the circular through hole, and four vertical plates 3014 are arranged in a ring at the lower end of the base plate 3011, and a connecting seat 3015 is formed on the outer side of each vertical plate 3014.

[0061] See Figure 6 It is known that the end of cylinder 302 furthest from the output end is machined with a threaded hole. The through hole 3013 of the base plate is aligned with the threaded hole, and bolts are installed to connect cylinder 302 to the base frame assembly 301. The telescopic end of cylinder 302 is machined with threads, and bracket 304 is sleeved on the telescopic end. The bracket 304 is pressed tightly onto the telescopic end of cylinder 302 by a nut, which is located below the bracket 304. Four shift forks 3041 are arranged in a circular array around the bracket 304, and each shift fork 3041 has a through hole at its end furthest from cylinder 302.

[0062] The structure of execution component 303 is as follows Figure 8 and Figure 9 As shown, there are four actuator components 303, evenly arranged around the cylinder 302. Each actuator component 303 mainly consists of a pressure block 3031, a first connecting rod 3032, a second connecting rod 3033, and a pressure block seat 3034. The pressure block seat 3034 has threaded holes, and the pressure block 3031 has through holes machined therein, with their positions corresponding one-to-one with the threaded holes on the pressure block seat 3034. The pressure block 3031 is fixed to the pressure block seat 3034 with bolts. On the side of the pressure block seat 3034 opposite to the pressure block 3031, a first connecting rod seat 30341 and a second connecting rod seat 30342 are formed. The first connecting rod seat 30341 is located at the upper end of the pressure block seat 3034 and is arranged along the width direction of the pressure block seat 3034, while the second connecting rod seat 30342 is located at the lower end of the pressure block seat 3034. Therefore, the first connecting rod 3032 and the second connecting rod 3033 are mounted on the first connecting rod seat 30341 and the second connecting rod seat 30342 via pins. Figure 5It can be seen that the other end of the first link 3032 is mounted on the connecting seat 3015 of the base frame assembly 301 by a pin, and the other end of the second link 3033 is connected to the shift fork 3041 of the bracket 304 by a pin.

[0063] Therefore, when the cylinder 302 extends, the support 304 moves downward in sync. One end of the second connecting rod 3033 connected to the shift fork 3041 moves downward with the support 304, while the other end of the second connecting rod 3033 swings about the second connecting rod seat 30342 as the axis and pushes the pressure block seat 3034 away from the cylinder 302. The pressure block seat 3034 moves upward as it moves outward, thereby causing the first connecting rod 3032 to rotate upward about the connecting seat 3015 as the axis, and the pressure block 3031 gradually presses the edge of the crystal rod.

[0064] When the actuator 303 is in the working state, the first link 3032 and the second link 3033 push the pressure block 3031 out. At this time, a part of the first link 3032 and the second link 3033 are located between the columns 2022 of the support frame 202, and the pressure block 3031 is located outside the support frame 202. When the actuator 303 is in the non-working state, the first link 3032 and the second link 3033 retract the pressure block 3031. At this time, the first link 3032 and the second link 3033 are located between the columns 2022 of the support frame 202, and the pressure block 3031 is located outside the support frame 202.

[0065] according to Figure 1 , Figure 3 as well as Figure 5 It can be seen that the clamping mechanism 300 is installed inside the support frame 202. The top plate connecting holes 2012 are evenly distributed around the circular through hole on the connecting top plate 201. The top plate connecting holes 2012 are through holes and their positions correspond to the bottom plate threaded holes 3012 on the bottom plate 3011. The base frame assembly 301 is fixed to the bottom of the connecting top plate 201 by bolts. The execution assembly 303 is placed in the notch between the columns 2022, thereby realizing the connection between the clamping mechanism 300 and the frame 200.

[0066] The crystal rod is cylindrical in shape. After being processed by a squaring machine, it becomes a long strip with a square cross-section and leaves four edge pieces. The inner side of the edge piece is flat and the outer side is arc-shaped. The edge piece gripping device 100 is connected to the top of the robotic arm during use, and the device is moved by the robotic arm.

[0067] During the crystal ingot squaring process, the connecting base plate 205 in the device keeps the end face of the crystal ingot pressed firmly to ensure that the crystal ingot remains stationary. After the crystal ingot is squared, four edge pieces are left. The device is then fastened to the ends of the four edge pieces. The enclosure 204 is arc-shaped, and its inner sidewall fits against the outer surface of the edge pieces. Then, the cylinder 302 in the device is activated. The telescopic end of the cylinder 302 extends downward, causing the support 304 to move downward. One end of the second connecting rod 3033 moves downward with the support 304, while the other end of the second connecting rod 3033 swings about the second connecting rod seat 30342 on the pressure block seat 3034, pushing the pressure block seat 3034 away from the cylinder 302. As the pressure block seat 3034 moves outward, it also moves upward, causing the first connecting rod 3032 to rotate upward about the connecting seat 3015. The pressure block 3031 gradually presses against the inner plane of the edge piece, cooperating with the enclosure 204 to clamp the edge piece. Finally, the robotic arm removes all four pieces of edge leather simultaneously. During the movement of the pressure block 3031, its outer plane remains parallel to the inner plane of the edge leather, ensuring that the force exerted by the pressure block 3031 on the edge leather is always perpendicular to the inner plane of the edge leather, thus preventing the edge leather from falling off during the gripping process.

[0068] The above embodiments are merely a more detailed description of the present utility model. For those skilled in the art, modifications or equivalent substitutions can still be made to the technical solutions in the foregoing embodiments. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model patent.
