Abstract
Description
Technical Field
[0001] This utility model relates to the field of graphite boat handling technology, and in particular to a semi-circular graphite boat gripper. Background Technology
[0002] A graphite boat, also known as a graphite mold, is a carrier that holds raw materials and components that need to be positioned or shaped, and then sintersects them at high temperatures. During production, the graphite boat is frequently gripped and moved within multiple spaces due to process requirements. Currently, two methods are used for gripping and moving graphite boats: side clamping and bottom lifting.
[0003] The side-clamping method for moving graphite boats utilizes the internal movement of the pneumatic gripper body to extend and retract the gripper connecting rod. When retracted, the space between the two gripper plates decreases, clamping the graphite boat from the side. A robotic arm then moves the graphite boat. While this side-clamping method, combined with a robotic arm, allows for movement within multiple spaces, the clamping force is difficult to control precisely, leading to problems such as cracked sidewalls or the graphite boat not being clamped at all. If clamping is used along the length, the gripper's strength may be insufficient due to the graphite boat's length, making it prone to falling.
[0004] The bottom-lifting method involves placing the graphite boat on a support plate, and then using a cylinder to drive the support plate and the graphite boat to move upwards or downwards, or slowly left or right. This method allows for short-distance movement of the graphite boat in two directions. However, the bottom-lifting method cannot be used for rapid transfer; it is only suitable for short-distance up-and-down and left-and-right slow movements and cannot achieve multi-directional movement.
[0005] Furthermore, due to the self-lubricating surface, long length, and unstable circular shape of the graphite boat, it cannot be grasped by vacuum adsorption, making it difficult to hold.
[0006] Therefore, how to solve the problems of existing graphite boat clamps being difficult to grasp, and being prone to falling or being cracked when grasping in the length direction, is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0007] To address the problems of existing graphite boat grippers being difficult to use, prone to falling off or cracking during length gripping, this utility model provides a semi-circular graphite boat gripper, comprising:
[0008] The pneumatic gripper fixing plate and the guide shaft fixing plate are disposed at both ends of the pneumatic gripper fixing plate and are perpendicularly connected to the pneumatic gripper fixing plate.
[0009] Two clamping plates are arranged opposite to and parallel to the guide shaft fixing plate; the clamping plates are spaced a certain distance from the guide shaft fixing plate, thus forming a clamping channel between them; anti-slip and shock-absorbing pads are provided on the inner side of the clamping plates;
[0010] A sliding device is connected between two clamping plates and is perpendicular to the two clamping plates;
[0011] A driving device is connected to a pneumatic gripper fixing plate. The clamping plate can move along the sliding device to approach or move away from the guide shaft fixing plate under the drive of the driving device to clamp or release the graphite boat.

Each pair of connecting rods is arranged in parallel and has a certain distance between them. The drive device drives the two pairs of connecting rods to move relative to or towards each other, thereby clamping or releasing the graphite boat.
[0016] Based on the above scheme, the two guide shafts are further connected by a double stop link, which is located on the outside of the clamping plate.
[0017] Based on the above scheme, further, the planes containing each pair of connecting rods intersect.

[0020] Based on the above scheme, the driving device is further installed below the pneumatic gripper fixing plate, and the driving device is a cylinder.
[0021] Based on the above scheme, a fall arrestor is further provided below the clamping plate along its edge, and the fall arrestor extends inward to the clamping plate.
[0022] Based on the above solution, a robotic arm connecting rod is further provided above the pneumatic gripper fixing plate, which can be connected to the robotic arm.
[0023] Furthermore, based on the above scheme, the outline below the clamping plate is arc-shaped.
[0024] Compared with the prior art, the semi-circular graphite boat gripper provided by this utility model consists of a pneumatic gripper fixing plate and a guide shaft fixing plate, clamping plates and anti-slip shock-absorbing pads located on both sides, a sliding device and a driving device, forming a gripper that can clamp inward and open outward with the middle as the reference. The gripper has a complete fixing frame, which gives the entire gripper a certain rigidity and provides sufficient strength for the gripping method in the length direction of the graphite boat, which can effectively prevent the graphite boat from falling or being cracked.

[0033] refer to Figure 1-3 An embodiment of a semi-circular graphite boat gripper provided by this utility model includes:
[0034] The pneumatic gripper fixing plate 100 and the guide shaft fixing plate 110 are provided at both ends of the pneumatic gripper fixing plate 100 and are perpendicularly connected to the pneumatic gripper fixing plate 100.
[0035] Two clamping plates 300 are arranged opposite to and parallel to the guide shaft fixing plate 110; the clamping plates 300 and the guide shaft fixing plate 110 are spaced apart by a certain distance, thus forming a clamping channel between the two; an anti-slip and shock-absorbing pad 310 is provided on the inner side of the clamping plates 300.
[0036] The sliding device 200 is connected between two clamping plates 300 and is perpendicular to the two clamping plates 300;
[0037] The driving device 130 is connected to the pneumatic gripper fixing plate 100. The clamping plate 300 can move along the sliding device 200 to approach or move away from the guide shaft fixing plate 110 under the drive of the driving device 130, clamping or releasing the graphite boat.
[0038] The sliding device 200 passes through the guide shaft fixing plate 110 and / or the driving device 130.
[0039] The specific working principle and process are as follows:
[0040] Power is provided by the drive device 130, causing the two clamping plates 300 to move towards the center simultaneously, reducing the distance between them. When the distance reaches a space corresponding to the length of the graphite boat, the anti-slip and shock-absorbing pads 310 on the clamping plates 300 contact and clamp the graphite boat at both ends, making the graphite boat and the clamping fixture a single unit. During clamping, the anti-slip and shock-absorbing pads 310 contact the graphite boat, generating friction between the pads and the boat. This prevents the graphite boat from falling during clamping and also provides cushioning between the clamping plates 300 and the graphite boat, preventing it from cracking.
[0041] like Figure 1-2 As shown, in one embodiment, the sliding device 200 includes at least two guide shafts 210 symmetrically arranged along the pneumatic gripper fixing plate 100. The guide shafts 210 pass through the guide shaft fixing plate 110, and linear bearings 211 are provided at both ends of the guide shafts 210. The linear bearings 211 are connected to the clamping plate 300. The guide shafts 210 pass through the through holes in the middle of the linear bearings 211, and their axes are parallel. The clamping plate 300 is driven by the driving device 130, so that it moves along the guide shafts 210 in a direction close to or away from the guide shaft fixing plate 110 through the linear bearings 211, thereby clamping or releasing the graphite boat.
[0042] and / or
[0043] The sliding device 200 includes at least two pairs of connecting rods 220 passing through the drive device 130. One pair of connecting rods 220 has its left end directly fixedly connected to the clamping plate 300 on the left side of the guide shaft fixing plate 110, or connected to the clamping plate 300 on the left side via a pneumatic gripper guide rod reinforcing plate 221. The other pair of connecting rods 220 has its right end directly fixedly connected to the clamping plate 300 on the right side of the guide shaft fixing plate 110, or connected to the clamping plate 300 on the right side via a pneumatic gripper guide rod reinforcing plate 221. Each pair of connecting rods 220 is arranged in parallel and has a certain distance between them. The drive device 130 drives the two pairs of connecting rods 220 to move relative to or towards each other, thereby clamping or releasing the graphite boat.
[0044] In one embodiment, such as Figure 1 and 3 As shown, the two guide shafts 210 are connected by a double stop link 212, which is located outside the clamping plate 300.
[0045] The purpose of adopting the above technical solution is to improve the stability and safety of the connection between the two guide shafts 210 and enhance the fixation.
[0046] In one embodiment, such as Figure 1 As shown, the planes containing each pair of connecting rods 220 intersect.
[0047] The purpose of adopting the above technical solution is to make each pair of connecting rods 220 staggered within a limited space, so as to make full use of the space.
[0048] In one embodiment, such as Figure 1 As shown, the anti-slip and shock-absorbing pad 310 is installed in a "U" shape along the lower edge of the clamping plate 300 on the inner side.
[0049] The purpose of adopting the above technical solution is to both generate friction between the anti-slip and shock-absorbing pad 310 and the contact surface of the graphite boat, and to save materials.
[0050] It should be noted that the "inner" in "inner side of clamping plate 300" refers to the side closer to the guide shaft fixing plate 110.
[0051] In one embodiment, the anti-slip and shock-absorbing pad 310 is made of any one of silicone rubber, polyurethane, or foamed rubber.
[0052] In one embodiment, such as Figure 1 and 2 As shown, the drive device 130 is installed below the pneumatic gripper fixing plate 100, and the drive device 130 is a cylinder.
[0053] In one embodiment, such as Figure 1 and 2 As shown, a fall arrestor plate 320 is provided below the clamping plate 300 along its edge, and the fall arrestor plate 320 extends inward toward the clamping plate 300.
[0054] The purpose of adopting the above technical solution is that the anti-fall plate 320 can prevent the graphite boat from falling under abnormal circumstances by supporting the bottom of the graphite boat.
[0055] In one embodiment, such as Figure 1 As shown, a robotic arm connecting rod 120 is provided above the pneumatic gripper fixing plate 100, which can be connected to the robotic arm.
[0056] The purpose of adopting the above technical solution is to enable the transfer of graphite boats by moving them within multiple spaces using a robotic arm outside the fixture.
[0057] Based on the above solutions, further, such as Figure 1 As shown, the outline below the clamping plate 300 is arc-shaped.
[0058] It should be noted that the outline of the clamping plate 300 includes, but is not limited to, the shape provided in this embodiment. The outline of the clamping plate 300 can be adjusted according to the specific shape of the graphite boat to adapt to the shape of the graphite boat and achieve better clamping in the length direction.

These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
