Description

Technical Field

[0001] The utility model relates to the technical field of graphite boat point repair, and specifically refers to a new type of graphite boat point loading and unloading tool. Background Technique

[0002] The graphite boat point is a device used to fix silicon wafers on the graphite boat. During the silicon wafer coating process, the graphite boat point ensures that the silicon wafers can be stably fixed on the graphite boat, preventing the silicon wafers from moving or sliding during the coating process, thereby ensuring the uniformity and quality of the coating. The traditional triangular point for graphite boats usually consists of a circular base and a triangular block. When in use, the block is snapped into the groove of the graphite boat, and the block is fixed by rotating the base. This structure is simple and effective, and can ensure the stable fixation of the silicon wafers. Another adjustable graphite boat point design includes an insulating rod and several unit boat pieces. There are gaps between each unit boat piece, and the silicon wafers are fixed through points and holes. This design allows the position of the points to be adjusted according to the needs of coating, improving the coating uniformity and the photoelectric conversion efficiency of the battery.

[0003] When a single graphite boat point inside the graphite boat is damaged, the traditional replacement method is to disassemble the entire graphite boat to remove the damaged point. During the disassembly process, the ceramic rod and the graphite boat piece of the graphite boat will be damaged. This loading and unloading method increases the loading and unloading time, increases the production cost, and improves the labor intensity of the personnel. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that in view of the above reasons, a graphite boat point loading and unloading tool is designed. During work, the damaged graphite boat points can be replaced in a timely manner, and it is not necessary to disassemble the entire graphite boat. Such an operation is beneficial for the quick repair and production input of the graphite boat damaged by individual graphite boat points.

[0005] To solve the above technical problem, the technical solution provided by the utility model is: a new type of graphite boat point loading and unloading tool, including a first handle and a second handle. The first handle and the second handle are symmetrically arranged. The first handle and the second handle are hinged to each other. There are arc gears meshing with each other between the upper ends of the first handle and the second handle. A first connecting rod is arranged above the first handle and higher than the arc gear. A second connecting rod is arranged above the second handle and higher than the arc gear. A thimble is arranged on the first connecting rod. A limiting block is arranged above the second connecting rod. A limiting hole is opened at the position corresponding to the thimble on the limiting block.

[0006] As a further solution of the utility model, the hinge point of the first handle and the second handle coincides with the center point of the arc gear.

[0007] As a further solution of the present utility model, the lower ends of the first grip and the second grip are provided with arcs conforming to the hand grip, and the lower ends of the first grip and the second grip are both coated with rubber layers.

[0008] As a further solution of the present utility model, the first connecting rod and the second connecting rod are rods with the same shape and symmetrically arranged, and the opposite sides of the first connecting rod and the second connecting rod are arranged in parallel.

[0009] As a further solution of the present utility model, the teeth on the two arc-shaped gears are arranged oppositely.

[0010] The advantages of the present utility model compared with the prior art are as follows:

[0011] 1. Clamp or loosen the first grip and the second grip by hand, drive the movement of the first connecting rod and the second connecting rod through the meshing of the arc-shaped gears, and the two connecting rods are respectively on both sides of the graphite boat sheet and fit the graphite boat sheet to maintain parallelism, forming clamping of the clamping point of the graphite boat, so as to ensure the clamping accuracy during the loading and unloading process.

[0012] 2. When disassembling the clamping point of the graphite boat, there is no reaction force when the clamping point is pushed out under the action of the limiting hole. When the ejector pin, the clamping point, and the limiting hole are on the same straight line, the clamped clamping point will loosen and fall off; when installing the clamping point of the graphite boat, the limiting hole can fix the clamping point of the graphite boat and play a limiting role when the clamping point of the graphite boat is pushed out. When the ejector pin, the clamping point, and the plane are on the same straight line, the installed clamping point will be clamped. The tool of the present utility model can play a role in timely replacing the damaged clamping points of the graphite boat, without the need to disassemble the entire graphite boat, reducing the labor intensity and improving the production efficiency. This tool has a simple composition and is suitable for front-line operators to replace the clamping points of the graphite boat. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0018] Combined with the attached Figure 1 , a new type of graphite boat clamping point loading and unloading tool includes a first grip 1 and a second grip 2. The first grip 1 and the second grip 2 are symmetrically arranged, and the first grip 1 and the second grip 2 are hinged to each other to play a role of clamping and loosening. The lower ends of the first grip 1 and the second grip 2 are set as arcs that fit the hand, which is convenient for the user to hold. The lower ends of the first grip 1 and the second grip 2 are both coated with rubber layers to increase the friction between the hand and the device and improve the anti-slip effect.

[0019] Combined with the attached Figure 1 , Figure 2 , between the upper ends of the first grip 1 and the second grip 2, there are arc-shaped gears 3 that mesh with each other.

The opposite sides of the connecting rod 1 4 and the connecting rod 2 5 are arranged in parallel. The arc gear 3 drives the connecting rod 1 4 and the connecting rod 2 5 to move through meshing. The working surfaces of the connecting rod 1 4 and the connecting rod 2 5 keep the graphite boat stuck point balanced for easy removal and installation. The connecting rod 1 4 is provided with an ejector pin 6, which serves to move the stuck point outward. In order to push the graphite boat, a limit block 7 is provided on the connecting rod 2 5, and a limit hole 8 is provided on the limit block 7 at a position corresponding to the position of the ejector pin 6. When the graphite boat card point is disassembled, there is no reaction force when the card point is pushed outward under the action of the limit hole 8. When the ejector pin 6, the card point and the limit hole 8 are in a straight line, the removed card point will loosen and fall off; when the graphite boat card point is installed, the limit hole 8 can fix the graphite boat card point and play a limiting role when the graphite boat card point is pushed outward. When the ejector pin 6, the card point and the plane are in a straight line, the installed card point will be clamped.

[0021] During the specific implementation of the utility model, the limiting hole is firstly aligned with the graphite boat card point to limit the graphite boat card point, and then the handle 1 and the handle 2 are held to drive the arc gear to rotate, and the meshing of the arc gear drives the movement of the connecting rod 1 and the connecting rod 2, and the two connecting rods are respectively on both sides of the graphite boat sheet and fit the graphite boat sheet to maintain parallelism, so as to clamp the graphite boat card point, thereby ensuring the clamping accuracy during the loading and unloading process, and at the same time, the connecting rod 1 drives the card point ejector to hold the card point, which is convenient for disassembly or installation.
