Description

Technical Field

[0001] This utility model relates to the field of composite material technology, and in particular to a multilayer composite structure graphite boat sheet. Background Technology

[0002] Multilayer composite graphite boats are precision components that integrate multiple layers of graphite materials or composite coatings with different properties. They are used in thin film deposition processes in the photovoltaic and semiconductor fields. This composite structure retains the inherent advantages of graphite materials such as high temperature resistance and good conductivity. Through multilayer synergistic optimization, it effectively solves the problems of easy wear, insufficient oxidation resistance and short service life of traditional graphite boats, and can significantly improve the production efficiency and finished product quality of battery cells or chips.

[0003] Existing multi-layer composite graphite boats use bolts to fasten the graphite boat and composite layer, achieving a detachable connection. However, to prevent direct tapping and cracking of the graphite or brittle composite layer, metal or alloy inserts need to be embedded in pre-drilled holes and fixed using high-temperature adhesives or sintering processes, which greatly increases production costs. Current technology uses tenon and mortise structures on the graphite boat and composite layer respectively, achieving connection through mechanical interlocking without additional fasteners. However, the tenon and mortise connection is a rigid interlocking, and once the composite layer wears down, it cannot be repaired by replacing fasteners; the entire component must be replaced, resulting in high maintenance costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-layer composite graphite boat sheet, which aims to improve the problem that the mortise and tenon connection in the prior art is a rigid interlocking joint, and once the composite layer is worn, it cannot be repaired by replacing the fasteners, but the whole component needs to be replaced, resulting in high maintenance costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-layer composite graphite boat sheet, comprising a sheet body, wherein multiple fixing mechanisms are installed on the front side of the outer wall of the sheet body, and the multiple fixing mechanisms are used for fixing; multiple connecting mechanisms are installed at the bottom end of the sheet body, and the multiple connecting mechanisms are used for connecting the sheet body to the graphite boat; each of the multiple fixing mechanisms includes a semi-ring frame, and the multiple semi-ring frames are installed on the front side of the outer wall of the sheet body; fixing plates are fixedly connected to the upper and lower sides of the outer wall of the semi-ring frame; multiple ceramic bolts are threaded into the interior of the multiple fixing plates; a sliding groove is opened in the middle of the semi-ring frame; and a driving component is installed inside the semi-ring frame.

[0006] As a further description of the above technical solution:

[0007] The drive assembly includes a fixed half-ring, which is installed inside the half-ring frame. A rotating shaft is fixedly connected inside the fixed half-ring. The front end of the outer wall of the rotating shaft is rotatably connected to the front end of the inner wall of the half-ring frame. A buckle plate is connected to the outer wall of the fixed half-ring, and the outer wall of the buckle plate is slidably connected to the inside of the slide groove.

[0008] As a further description of the above technical solution:

[0009] Each of the multiple connecting mechanisms includes a clamping frame, and the multiple clamping frames are installed at the bottom end of the sheet body. A limiting groove is formed inside the clamping frame, and a locking mechanism is installed in the middle of the clamping frame.

[0010] As a further description of the above technical solution:

[0011] The engaging mechanism includes a hexagonal head installed in the middle of the engaging mechanism. A bidirectional threaded rod is fixedly connected to the rear side of the outer wall of the hexagonal head. The front and rear ends of the outer wall of the bidirectional threaded rod are rotatably connected to the interior of the clamping frame. Multiple threaded plates are installed on the outer wall of the bidirectional threaded rod. The bottom ends of the multiple threaded plates are threadedly connected to the outer wall of the bidirectional threaded rod. The outer wall of the threaded plate is slidably connected to the interior of the limiting groove. A buckle is fixedly connected to the outer wall of the threaded plate. Multiple slots are opened at the bottom end of the plate. The interior of the multiple slots is slidably connected to the outer wall of the buckle.

[0012] As a further description of the above technical solution:

[0013] An impact-resistant layer is installed inside the front end of the sheet body, and multiple fixing mechanisms are installed on the outer wall of the impact-resistant layer.

[0014] As a further description of the above technical solution:

[0015] Multiple stamping bolts are fixedly connected to the rear side of the outer wall of the impact-resistant layer, and multiple stamping grooves are opened inside the front end of the sheet body. The interior of the stamping grooves is slidably connected to the outer wall of the stamping bolts.

[0016] As a further description of the above technical solution:

[0017] The middle part of the sheet has multiple honeycomb grooves, and all of the honeycomb grooves adopt a hexagonal design.

[0018] As a further description of the above technical solution:

[0019] Multiple flow channels are provided at both the upper and lower ends of the sheet, and all of the multiple flow channels adopt an arc edge design.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, a fixing mechanism is fixed at the connection between the sheet body and the impact-resistant layer. By turning the buckle plate in the two fixing mechanisms, the two fixing half rings are driven to rotate synchronously. Since the rotating shaft can rotate inside the half ring frame, when the fixing half ring rotates, the other half rotates out into the half ring frame of the adjacent fixing mechanism. Through the cooperation of the two fixing mechanisms, the impact-resistant layer and the sheet body are quickly fixed. When the impact-resistant layer is worn, it can be removed and replaced by turning the buckle plate in the opposite direction. There is no need to replace the entire graphite boat sheet, and the maintenance cost is low.

[0022] 2. In this utility model, when the hexagonal head is rotated, the bidirectional threaded rod welded to its rear side rotates inside the clamping frame. The two threaded plates on the outer side of the bidirectional threaded rod can slide in the limiting groove. Due to the rotation restriction of the limiting groove, when the bidirectional threaded rod rotates, the two threaded plates can only move in opposite directions along their axial diameter, which drives the buckle welded to the outer wall to move. Adjusting the position of the two threaded plates can make the buckle securely engaged in the slot, realizing the connection between the sheet and the graphite boat. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 4 , Figure 5 and Figure 6 This utility model provides an embodiment of a multi-layer composite graphite boat sheet, comprising a sheet body 1. Multiple fixing mechanisms 2 are installed on the front side of the outer wall of the sheet body 1, each fixing mechanism 2 being used for fixing. Multiple connecting mechanisms 3 are installed at the bottom end of the sheet body 1, each connecting mechanism 3 being used to connect the sheet body 1 to the graphite boat. Each fixing mechanism 2 includes a semi-ring frame 201, which is installed on the front side of the outer wall of the sheet body 1. Fixing plates 202 are fixedly connected to the upper and lower sides of the outer wall of the semi-ring frame 201. The internal threads of the fixing plates 202 are... Multiple ceramic bolts 203 are connected. A sliding groove 204 is opened in the middle of the semi-ring frame 201. A drive assembly 205 is installed inside the semi-ring frame 201. The drive assembly 205 includes a fixed semi-ring 2051, which is installed inside the semi-ring frame 201. A rotating shaft 2052 is fixedly connected inside the fixed semi-ring 2051. The front end of the outer wall of the rotating shaft 2052 is rotatably connected to the front end of the inner wall of the semi-ring frame 201. A buckle plate 2053 is connected to the outer wall of the fixed semi-ring 2051. The outer wall of the buckle plate 2053 is slidably connected to the inside of the sliding groove 204.

[0035] Specifically, there are fixing mechanisms 2 at the connection between the sheet body 1 and the impact-resistant layer 4. The fixing mechanisms 2 are all made of insulating non-metallic material. By bending the buckle plate 2053 in the two fixing mechanisms 2, the two fixing half rings 2051 are driven to rotate synchronously. Since the rotating shaft 2052 can rotate inside the half ring frame 201, when the fixing half ring 2051 rotates, its other half will rotate into the interior of the half ring frame 201 in the adjacent fixing mechanism 2, forming a ring-shaped fixation. Through the cooperation of the two fixing mechanisms 2, the impact-resistant layer 4 and the sheet body 1 are quickly fixed, ensuring that the connection between the two is stable. If the impact-resistant layer 4 is worn, it can be removed and replaced simply by bending the buckle plate 2053 in the opposite direction. It is not necessary to replace the entire graphite boat sheet, thus reducing maintenance costs.

[0036] Reference Figure 3 , Figure 4 and Figure 7 Each of the multiple connecting mechanisms 3 includes a clamping frame 301, which is installed at the bottom of the plate 1. A limiting groove 302 is formed inside the clamping frame 301. A locking mechanism 303 is installed in the middle of the clamping frame 301. The locking mechanism 303 includes a hexagonal head 3031, which is installed in the middle of the locking mechanism 303. A bidirectional threaded rod 3032 is fixedly connected to the rear side of the outer wall of the hexagonal head 3031. The front and rear ends of the outer wall of the bidirectional threaded rod 3032 are connected to the clamping frame. The internal rotating connection of 301 is provided. Multiple threaded plates 3033 are installed on the outer wall of the bidirectional threaded rod 3032. The bottom end of each threaded plate 3033 is threadedly connected to the outer wall of the bidirectional threaded rod 3032. The outer wall of the threaded plate 3033 is slidably connected to the inside of the limiting groove 302. A buckle 3034 is fixedly connected to the outer wall of the threaded plate 3033. Multiple slots 3035 are opened at the bottom end of the plate 1. The inside of each slot 3035 is slidably connected to the outer wall of the buckle 3034.

[0037] Specifically, the connecting mechanism 3 is made of non-metallic material. When the hexagonal head 3031 is rotated, the bidirectional threaded rod 3032 on its rear side can rotate inside the clamping frame 301. Since the two threaded plates 3033 on the outer side of the bidirectional threaded rod 3032 can slide in the limiting groove 302, when the bidirectional threaded rod 3032 rotates, the rotation is restricted by the limiting groove 302, so that the two threaded plates 3033 can only move in opposite directions along the axial diameter of the bidirectional threaded rod 3032, thereby driving the buckle 3034 on its outer wall to move. By adjusting the position of the two threaded plates 3033, the buckle 3034 can be securely engaged in the slot 3035, realizing the connection between the sheet 1 and the graphite boat.

[0038] Reference Figure 1 , Figure 2 and Figure 3An impact-resistant layer 4 is installed inside the front end of the sheet body 1. Multiple fixing mechanisms 2 are installed on the outer wall of the impact-resistant layer 4. Multiple stamping bolts 5 are fixedly connected to the rear side of the outer wall of the impact-resistant layer 4. Multiple stamping grooves 6 are opened inside the front end of the sheet body 1. The interior of the stamping grooves 6 is slidably connected to the outer wall of the stamping bolts 5. Multiple honeycomb grooves 8 are opened in the middle of the sheet body 1. The multiple honeycomb grooves 8 are all hexagonal in design. Multiple flow guide grooves 7 are opened at the upper and lower ends of the sheet body 1. The multiple flow guide grooves 7 are all arc-edged in design.

[0039] Specifically, the front end of the sheet body 1 is equipped with an impact-resistant layer 4, which can enhance the impact resistance of the sheet body 1. The impact-resistant layer 4 is equipped with multiple fixing mechanisms 2 for fixing the impact-resistant layer 4 to the sheet body 1. Multiple stamping bolts 5 are provided on the rear side of the impact-resistant layer 4. A stamping groove 6 is provided at the corresponding position inside the front end of the sheet body 1 to provide positioning for the installation of the impact-resistant layer 4. The middle part of the sheet body 1 has multiple honeycomb grooves 8. The honeycomb grooves 8 are all hexagonal in design, which makes the force distribution more uniform and improves the heat dissipation performance of the sheet body 1. Multiple flow guide grooves 7 are provided on the sheet body 1 to guide the flow of liquid or gas.

[0040] Working principle: Fixing mechanisms 2 are fixed at the connection between the sheet body 1 and the impact-resistant layer 4. By turning the buckle plate 2053 in the two fixing mechanisms 2, the two fixing half rings 2051 are driven to rotate synchronously. Since the rotating shaft 2052 can rotate inside the half ring frame 201, when the fixing half ring 2051 rotates, its other half will rotate into the half ring frame 201 in the adjacent fixing mechanism 2. Through the cooperation of the two fixing mechanisms 2, the impact-resistant layer 4 and the sheet body 1 are quickly fixed. If the impact-resistant layer 4 is worn, it can be removed and replaced by turning the buckle plate 2053 in the opposite direction. It is not necessary to replace the entire graphite boat sheet, so the maintenance cost is low.

[0041] Rotating the hexagonal head 3031 allows the bidirectional threaded rod 3032 welded to its rear side to rotate inside the clamping frame 301. Since the two threaded plates 3033 on the outer side of the bidirectional threaded rod 3032 can slide within the limiting groove 302, when the bidirectional threaded rod 3032 rotates, the rotation restriction of the limiting groove 302 causes the two threaded plates 3033 to move in opposite directions along the axial diameter of the bidirectional threaded rod 3032, thereby driving the buckle 3034 welded to its outer wall to move. By adjusting the position of the two threaded plates 3033, the buckle 3034 can be securely engaged in the slot 3035, realizing the connection between the sheet 1 and the graphite boat.
