Description

Technical Field

[0001] The utility model relates to the technical field of locking mechanisms, in particular to a locking mechanism for automatic calibration of a graphite boat. Background Technique

[0002] A graphite boat is a carrier for photovoltaic cells, and its structure is composed of several graphite boat plates fixed together by bolts. After the graphite boat has been used for a period of time, it usually needs to be calibrated. In order to ensure the stability of the graphite boat during calibration, a locking mechanism is mostly used to fix it.

[0003] For example, an automatic boat calibration machine with the publication number of CN113113337A includes: a calibration device, and the calibration device includes a calibration mechanism and a shaking mechanism arranged on the base; a clamping plate mechanism for clamping and fixing the graphite boat; a bolt tightening and loosening mechanism for loosening or tightening the bolts on the graphite boat; the bolt tightening and loosening mechanism needs the clamping plate mechanism to cooperate to clamp and fix the graphite boat when tightening or loosening the bolts on the graphite boat, and the shaking mechanism needs the bolt tightening and loosening mechanism to loosen the bolts and then tighten the bolts respectively before and after shaking the graphite boat.

[0004] Among them, the following technical problems exist in the above-mentioned prior art: when the existing graphite boat calibration machine fixes the graphite boat, it can usually only fix the graphite boat in two directions, and the overall stability is poor. It is not convenient to synchronously limit the four directions of the graphite boat during calibration. Therefore, when the graphite boat is offset due to force, it is easy to affect the subsequent calibration effect of the graphite boat. At the same time, when the graphite boat is limited, it is not convenient to play a clamping and buffering role, and it is easy to cause deformation at the clamped part of the graphite boat due to excessive clamping force.

[0005] Therefore, we propose a locking mechanism for automatic calibration of a graphite boat to solve the problems raised above. Content of the Utility Model

[0006] The purpose of the utility model is to provide a locking mechanism for automatic calibration of a graphite boat to solve the problems raised in the above background technique, that is, when the existing graphite boat calibration machine on the current market fixes the graphite boat, it can usually only fix the graphite boat in two directions, and the overall stability is poor. It is not convenient to synchronously limit the four directions of the graphite boat during calibration. Therefore, when the graphite boat is offset due to force, it is easy to affect the subsequent calibration effect of the graphite boat. At the same time, when the graphite boat is limited, it is not convenient to play a clamping and buffering role, and it is easy to cause deformation at the clamped part of the graphite boat due to excessive clamping force.

[0007] To achieve the above object, the present utility model provides the following technical solution: A locking mechanism for automatic calibration of a graphite boat, including a support base, a positioning and limiting frame is fixedly connected to the left side of the upper end of the support base, and a movable limiting frame is installed on the right side of the upper end of the support base. The lower end of the movable limiting frame is fixedly connected to the telescopic end of a pushing cylinder, and the pushing cylinder is fixed on the support base;

[0008] It further includes:

[0009] Connecting blocks are fixedly connected to the front and rear sides of the movable limiting frame, and pressure-applying guiding blocks are fixedly connected to the connecting blocks. A lateral locking rod is arranged on the side of the pressure-applying guiding block, and the lateral locking rod is installed through a clamping plate. The clamping plate is fixed on the support base, and the lateral locking rod is connected to the clamping plate through an auxiliary spring;

[0010] Buffer components are installed at the ends of the movable limiting frame and the lateral locking rod, and the buffer components play an elastic buffering role when clamping the side of the graphite boat.

[0011] Preferably, the movable limiting frame and the positioning and limiting frame are symmetrically distributed on the upper end of the support base, and the movable limiting frame and the positioning and limiting frame are arranged parallel to each other.

[0012] By adopting the above technical solution, the clamping and positioning of the graphite boat can be facilitated through the arrangement of the movable limiting frame and the positioning and limiting frame.

[0013] Preferably, the pressure-applying guiding block and the connecting block are of an integrally formed structure, and the pressure-applying guiding blocks correspond to the lateral locking rods one by one.

[0014] By adopting the above technical solution, when the connecting block moves along with the movable limiting frame, the connecting block can drive the pressure-applying guiding block to move synchronously.

[0015] Preferably, the cross-section of the pressure-applying guiding block is set as a right-angled triangle structure, and the hypotenuse of the pressure-applying guiding block is in mutual fit with the spherical end of the lateral locking rod.

[0019] Preferably, the buffer member includes a buffer plate, guide rods, and adjusting springs. The guide rods are fixedly connected to the buffer plate, and the guide rods are interconnected with the lateral locking rods and the movable limiting frames through the adjusting springs.

[0020] By adopting the above technical solution, through the elastic deformation of the adjusting spring after the buffer plate moves, the clamping and buffering effect can be achieved, avoiding damage to the graphite boat due to excessive clamping force.

Specific embodiments

[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] Embodiment 1: Please refer to Figures 1-6 , when the existing graphite boat calibrator fixes the graphite boat, it can usually only fix the graphite boat in two directions, and the overall stability is poor. It is not convenient to synchronously limit the four directions of the graphite boat during calibration. Therefore, when the graphite boat is offset due to force, it is likely to affect the subsequent calibration effect of the graphite boat. To solve this technical problem, the following technical content is disclosed in this embodiment;

[0036] A locking mechanism for automatic calibration of a graphite boat, comprising a support base 1. A positioning and limiting frame 2 is fixedly connected to the left side of the upper end of the support base 1, and a movable limiting frame 3 is installed on the right side of the upper end of the support base 1. The lower end of the movable limiting frame 3 is fixedly connected to the telescopic end of a pushing cylinder 4, and the pushing cylinder 4 is fixed on the support base 1. Connecting blocks 5 are fixedly connected to the front and rear sides of the movable limiting frame 3, and pressure-applying guiding blocks 6 are fixedly connected to the connecting blocks 5. A lateral locking rod 7 is arranged on the side of the pressure-applying guiding block 6, and the lateral locking rod 7 is installed through a clamping plate 8 which is fixed on the support base 1. The lateral locking rod 7 is connected to the clamping plate 8 through an auxiliary spring 9. The movable limiting frame 3 and the positioning and limiting frame 2 are symmetrically distributed on the upper end of the support base 1, and the movable limiting frame 3 and the positioning and limiting frame 2 are arranged in parallel. The pressure-applying guiding block 6 and the connecting block 5 are of an integrally formed structure, and the pressure-applying guiding blocks 6 correspond to the lateral locking rods 7 one by one. The cross-section of the pressure-applying guiding block 6 is arranged in a right-angled triangle structure, and the hypotenuse of the pressure-applying guiding block 6 is in contact with the spherical end of the lateral locking rod 7. The lateral locking rod 7 and the clamping plate 8 are vertically distributed, and the lateral locking rod 7 and the clamping plate 8 form an elastic telescopic structure through the auxiliary spring 9.

[0037] When it is necessary to calibrate and lock the graphite boat, the graphite boat is placed on the support base 1. At this time, by starting the pushing cylinder 4, the movable limiting frame 3 can be moved after the pushing cylinder 4 is started, so that the graphite boat is fixed between the movable limiting frame 3 and the positioning and limiting frame 2. At the same time, after the movable limiting frame 3 moves, the connecting block 5 can drive the pressure-applying guiding block 6 to move synchronously. After the pressure-applying guiding block 6 moves, it can use the hypotenuse to squeeze and push the spherical end of the lateral locking rod 7, and the lateral locking rod 7 moves inward to the inside of the clamping plate 8 under the force. The front and rear directions of the graphite boat can be fixed through the moving lateral locking rod 7, so as to realize multi-directional fixation of the graphite boat and ensure the stability of the graphite boat during calibration.

[0038] Embodiment 2: The technical content disclosed in this embodiment is a further improvement based on the above Embodiment 1. When the graphite boat is limited, it is not easy to play a clamping and buffering role, and it is easy to cause deformation at the clamped part of the graphite boat due to excessive clamping force. In order to further solve this technical problem, the following technical content is disclosed in this embodiment, as Figures 4-6 shown;

[0039] Buffer components 10 are installed at the ends of the movable limit frame 3 and the lateral locking rod 7, and the buffer components 10 play an elastic buffering role when clamping the side of the graphite boat. The buffer component 10 includes a buffer plate 101, a guide rod 102, and an adjusting spring 103. The buffer plate 101 is fixedly connected with the guide rod 102, and the guide rods 102 are connected to the lateral locking rod 7 and the movable limit frame 3 through the adjusting spring 103 respectively. The contact surface of the buffer plate 101 with the graphite boat is set as a rough surface, and two guide rods 102 are fixedly connected to the buffer plate 101, and the two guide rods 102 are symmetrically arranged about the horizontal central axis of the buffer plate 101.

[0040] When the movable limit frame 3 and the lateral locking rod 7 lock and fix the graphite boat, the buffer plates 101 on the movable limit frame 3 and the lateral locking rod 7 first contact the side of the graphite boat. After the buffer plate 101 is stressed, it can make the guide rods 102 move synchronously. When the guide rods 102 move, the adjusting spring 103 can be elastically deformed. Through the elastic deformation of the adjusting spring 103, a clamping and buffering effect can be achieved, avoiding damage to the graphite boat caused by excessive clamping force. At the same time, the surface of the buffer plate 101 is a rough surface, so the contact friction between the buffer plate 101 and the side of the graphite boat can be increased, and the stability of limiting the graphite boat can be improved.

[0041] The content not described in detail in this specification belongs to the prior art well known to those skilled in the art.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
