When calibrating the graphite boat, in order to facilitate the taking and placing of the graphite boat, a corresponding telescopic material taking and placing mechanism is usually used. Through the automated telescopic material taking and placing mechanism, manual operation is replaced, and the overall degree of automation is improved.

[0003] For example, an automated device for realizing full-automatic calibration, locking and detection of a graphite boat with the publication number of CN115233194A includes: a machine table large plate, a fixing system, a locking system, a positioning system and a detection system; the machine table large plate is installed on the equipment rack; the fixing system is installed on the machine table large plate and is used to realize the automatic positioning and clamping functions of the graphite boat; the positioning system is installed on the machine table large plate and is used to realize the parallelism positioning of the graphite boat; the locking system is installed on the machine table large plate and is used for the precise locking of the locking nut and the precise control of the width of the graphite boat; the detection system is installed on the machine table large plate and is used for the detection of the graphite boat.

[0004] Among the above-mentioned existing technologies, there are the following technical problems: when the existing graphite boat automated equipment feeds the graphite boat, the overall stroke is short. Usually, a single cylinder and a guide rail are used as the graphite boat pushing components. In order to push the graphite boat a longer distance, a cylinder with a larger stroke needs to be set, and a cylinder with a larger stroke will occupy too much space. At the same time, when pushing the graphite boat, it is not convenient to stably limit the graphite boat, thus reducing the stability of the graphite boat when it is pushed.

[0005] Therefore, we propose a telescopic material taking and placing mechanism for a graphite boat to solve the problems raised above. Content of the Utility Model

In order to push the graphite boat a longer distance, a cylinder with a larger stroke needs to be set, and a cylinder with a larger stroke will occupy too much space. At the same time, when pushing the graphite boat, it is not convenient to stably limit the graphite boat, thus reducing the stability of the graphite boat when it is pushed.

[0010] Preferably, the inner wall of the limiting frame and the outer wall of the first guiding slide rail are mutually attached, and the limiting frame can slide linearly on the first guiding slide rail.

[0011] By adopting the above technical solution, the inner wall of the limiting frame and the outer wall of the first guiding slide rail are mutually attached, so as to ensure the stability of the limiting frame when moving on the first guiding slide rail.

[0012] Preferably, the conveying mechanism is composed of a motor, two belt pulleys and a belt. The motor is fixed on the limiting frame. The output end of the motor is connected to one of the belt pulleys, and a belt is sleeved between the two belt pulleys, and the positioning block is fixedly connected to the belt.

[0013] By adopting the above technical solution, when the motor drives one of the belt pulleys to rotate, the other belt pulley can be synchronously rotated by using the belt.

[0014] Preferably, the longitudinal section of the clamping block is set as an isosceles trapezoid structure, and the outer wall of the clamping block and the inner wall of the groove on the side of the graphite boat body are mutually attached.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Example 1: Please refer to Figures 1 - 4, when the existing graphite boat automation equipment feeds the graphite boat, the overall stroke is short. Usually, a single cylinder and a guide rail are used as the pushing components for the graphite boat. In order to push the graphite boat a longer distance, a cylinder with a larger stroke needs to be set, but the cylinder with a larger stroke will occupy too much space. To solve this technical problem, the following technical content is disclosed in this embodiment;

[0035] A telescopic loading and unloading mechanism for a graphite boat, including a connecting frame 1. A pushing cylinder 2 is fixedly connected to the connecting frame 1, and the telescopic end of the pushing cylinder 2 is fixedly connected to a limiting frame 3. The limiting frame 3 is installed on a first guiding slide rail 4, and the first guiding slide rail 4 is fixed to the connecting frame 1; a conveying mechanism 5 is installed on the side of the limiting frame 3, and a positioning block 6 is installed on the conveying mechanism 5. The positioning block 6 is fixed to a movable arm 7, and the movable arm 7 is installed on a second guiding slide rail 8. The second guiding slide rail 8 is fixed to the side of the limiting frame 3. One end of the movable arm 7 far from the positioning block 6 is fixedly connected to a clamping block 9, and the clamping block 9 is inserted into a groove on the side of the graphite boat body 10 that is mutually adapted. The inner wall of the limiting frame 3 and the outer wall of the first guiding slide rail 4 are mutually attached, and the limiting frame 3 can slide linearly on the first guiding slide rail 4. The conveying mechanism 5 is composed of a motor, two belt pulleys and a belt. The motor is fixed to the limiting frame 3, the output end of the motor is connected to one of the belt pulleys, and a belt is sleeved between the two belt pulleys, and the positioning block 6 is fixedly connected to the belt. The longitudinal section of the clamping block 9 is set as an isosceles trapezoid structure, and the outer wall of the clamping block 9 and the inner wall of the groove on the side of the graphite boat body 10 are mutually attached.

[0036] When it is necessary to load and unload the graphite boat body 10, the clamping block 9 is clamped into the groove on the side of the graphite boat body 10. Since the outer wall of the clamping block 9 and the inner wall of the groove on the side of the graphite boat body 10 are mutually attached, the stability of the clamping block 9 in the groove on the side of the graphite boat body 10 can be ensured. At this time, by opening the pushing cylinder 2, the limiting frame 3 can be extended. After the limiting frame 3 moves, it moves on the first guiding slide rail 4. Then, the motor is used to control the belt pulleys and the belt for transmission. After the belt is transmitted, the positioning block 6 fixed on it can move synchronously. After the positioning block 6 moves, the movable arm 7 can move synchronously. By the movement of the movable arm 7, the graphite boat body 10 at the front end can be pushed secondarily, thereby realizing the automatic telescopic loading and unloading of the graphite boat body 10.

[0037] Embodiment 2: The technical content disclosed in this embodiment is a further improvement based on the above Embodiment 1. When pushing the graphite boat, it is not convenient to stably limit the graphite boat, thereby reducing the stability of the graphite boat when it is pushed. To further solve this technical problem, the following technical content is disclosed in this embodiment, as Figures 1 - 6 shown;

[0038] A through slot 11 is provided on the side of the block 9, and a stabilizing component 12 is installed on the block 9. The through slot 11 extending from the side of the block 9 by the stabilizing component 12 contacts the side slot of the graphite boat body 10, thereby improving the stability of the graphite boat body 10 when moving. The stabilizing component 12 includes a servo motor 121, and the servo motor 121 is fixed inside the block 9. A transmission screw 122 is fixedly connected to the output end of the servo motor 121, and a moving block 123 is connected to the transmission screw 122. A horizontal rod 124 is provided on the side of the moving block 123, and the horizontal rod 124 is connected to the inside of the block 9 through a booster spring 125, and a pressure plate 126 is fixedly connected to one end of the horizontal rod 124 away from the moving block 123. The middle part of the moving block 123 is threadedly connected to the transmission screw 122, and the moving block 123 and the block 9 are slidably connected. The outer side of the lower end of the moving block 123 and the spherical end of the horizontal rod 124 fit each other, and the fitting surface of the moving block 123 and the spherical end of the horizontal rod 124 is set as a hypotenuse, and the horizontal rod 124 forms an elastic telescopic structure through the assist spring 125 and the clamping block 9.

[0039] When the block 9 is inserted into the groove on the side of the graphite boat body 10, the servo motor 121 is turned on. After the servo motor 121 is turned on, the transmission screw 122 can be rotated. After the transmission screw 122 rotates, the threaded moving block 123 can be moved downward. Through the movement of the moving block 123, the spherical end of the horizontal rod 124 can be squeezed and pushed by the hypotenuse. After the horizontal rod 124 is pressed, it can drive the pressure plate 126 to extend out of the through groove 11. At this time, the pressure plate 126 and the groove on the side of the graphite boat body 10 conflict with each other, thereby further ensuring the stability of the graphite boat body 10 when being pushed.
