Description

Technical Field

[0001] This invention relates to the field of graphite boat calibration technology, specifically to an automated graphite boat installation and calibration machine. Background Technology

[0002] A graphite boat is a carrier used to support photovoltaic cells. Its structure consists of several graphite boat sheets fixed together by bolts. Graphite boats need to operate in various environments during use. Different graphite boat sheets generate different internal stresses, which will cause the graphite boat sheets to deform to varying degrees. Therefore, after a period of use, graphite boats need to be reassembled by a calibration machine to eliminate the internal stress.

[0003] For example, a graphite boat calibration device, disclosed in CN219824352U, includes a reference base, a calibration base, a lifting drive mechanism, and a tightening mechanism. The reference base has multiple first positioning slots, which are parallel and spaced apart, and are used to accommodate the boat blades of the graphite boat. The reference base is positioned above the calibration base and has multiple second positioning slots, which correspond one-to-one with the first positioning slots in the vertical direction. The lifting drive mechanism is connected to the calibration base and is used to drive the calibration base to move closer to or away from the reference base. The tightening mechanism is located beside the reference base and is used to loosen or tighten the threaded fasteners of the graphite boat.

[0004] The existing technology has the following technical problems: When the existing calibration device is used to tighten the threaded fasteners on the graphite boat through its tightening mechanism, the tightening mechanism can only adapt to the tightening of nuts of a certain size. When the size of the nuts on different graphite boats is different, the tightening mechanism cannot be adapted to the nuts. At the same time, when tightening the nuts, it is not convenient to tighten the bolts, which can easily cause the bolts and nuts to rotate synchronously. In addition, when tightening the nuts, it is not convenient to lubricate the threads on the bolts. When the surface of the bolts is covered with dirt or has rust, there is a large resistance between the nut and the bolt. When the tightening mechanism forcibly tightens the nuts, it can easily damage the threads.

[0005] Therefore, we propose an automated graphite boat installation and calibration machine to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide an automated graphite boat installation and calibration machine to solve the problems mentioned in the background art. In existing calibration devices on the market, the tightening mechanism can only accommodate nuts of a certain size. When nuts on different graphite boats vary in size, the tightening mechanism cannot be matched to the nuts. Furthermore, when tightening the nuts, it is inconvenient to press the bolts, easily causing the bolts and nuts to rotate synchronously. Additionally, when tightening the nuts, it is inconvenient to lubricate the threads on the bolts. When the bolt surface is covered with dirt or rust, there is significant resistance between the nut and the bolt. Forcibly tightening the nut by the tightening mechanism can easily damage the threads.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an automated graphite boat installation and calibration machine, comprising a connecting frame, a support base fixedly connected to the middle of the connecting frame, a positioning frame installed on the front side of the upper end of the support base, a movable frame installed on the rear side of the upper end of the support base, and the lower end of the movable frame being connected to the telescopic end of a limit cylinder. Also includes: The support base has guide rails installed on its front and rear sides, and a movable seat is installed on the guide rails. A lifting frame is installed on the movable seat, and an adjusting cylinder is fixedly connected to the side of the lifting frame. The telescopic end of the adjusting cylinder is fixed to the guide seat, and a laser sensor is installed on the guide seat. A servo motor is fixedly connected to the side of the guide seat, and a tensioning rod for tightening nuts is connected to the output end of the servo motor. An adjusting lubrication component is installed on the tensioning rod for pressing the bolt against the bolt and spraying oil to lubricate the surface threads of the bolt.

[0008] Preferably, the positioning frame and the movable frame are symmetrically arranged about the transverse central axis of the support base, and the movable frame and the support base are slidably connected.

[0009] By adopting the above technical solution, the graphite boat placed between the positioning frame and the movable frame can be easily clamped by sliding the movable frame on the support base.

[0010] Preferably, the regulating lubrication component includes a pressure rod located in the middle of the tensioning rod. The pressure rod is inserted into the interior of the guide post and is connected to the interior of the guide post via an auxiliary spring. The guide post is connected to the interior of the tensioning rod via a return spring. The interior of the guide post is connected to a locking post via an air supply hose, and the locking post is fixed to the side of the tensioning rod. A connecting rod is installed on the side of the locking post, and one side of the connecting rod is inserted into the interior of the locking post. A fixing post is installed in the middle of the connecting rod, and the fixing post is connected to the interior of the connecting rod via a built-in spring. One end of the rod extending into the docking rod forms an oil storage chamber with the interior of the docking rod. An oil injection pipe is installed on the side of the oil storage chamber. The oil storage chamber is connected to each other through an oil suction pipe and an oil storage ring. Both the oil injection pipe and the oil suction pipe are equipped with one-way valves. The oil storage ring is fixed to a tension rod. A side block is fixedly connected to the end of the guide column, and an insertion rod is fixedly installed on the side block. The insertion rod is inserted into the interior of the mixing column, and the mixing column is mounted on the side of the oil storage ring through a bearing. A locking block is fixedly connected to the side of the insertion rod extending into the interior of the mixing column, and the locking block is inserted into the interior of the drive groove, which is located inside the mixing column.

[0011] Preferably, the surface of the end of the pressure rod extending out of the guide post is roughened, and the end of the pressure rod extending into the guide post forms a seamless sliding connection structure with the guide post through a circumferentially fixed sealing ring.

[0012] By adopting the above technical solution, the contact friction between the pressure rod and the bolt can be improved through the rough surface of the end of the pressure rod.

[0013] Preferably, the airflow inside the guide post is interconnected with the airflow inside the snap-fit ​​post through the air delivery hose, and the snap-fit ​​post has a hollow structure inside, allowing the docking rod to slide on the snap-fit ​​post.

[0014] By adopting the above technical solution, when the pressure rod moves inside the guide column, the airflow inside the guide column can enter the interior of the clamping column through the air supply hose. The increase in airflow inside the clamping column will push the docking rod to move.

[0015] Preferably, the end of the fixing column is connected to the oil storage chamber inside the connecting rod through a fixed sealing ring to form a seamless sliding connection structure, and the fixing column and the connecting rod are symmetrically arranged about the transverse central axis of the tensioning rod.

[0016] By adopting the above technical solution, the nuts can be easily clamped and fixed through the symmetrically distributed fixing columns and connecting rods.

[0017] Preferably, the ends of the lateral block and the guide post are welded together, and the lateral block and the guide post can slide on the tension rod, and the lateral block and the insert are vertically distributed.

[0018] By adopting the above technical solution, the guide post can slide on the tension rod, thereby enabling the side block and the insertion rod to move synchronously.

[0019] Preferably, the outer wall of the locking block at the end of the insertion rod and the inner wall of the driving groove are in contact with each other, and the driving groove is configured as a spiral structure.

[0020] By adopting the above technical solution, the outer wall of the end block of the insertion rod and the inner wall of the drive groove are in close contact with each other, thereby ensuring the stability of the insertion rod moving in the drive groove. At the same time, by utilizing the movement of the block in the drive groove, the mixing column can be rotated synchronously.

[0021] Preferably, the mixing column is rotatable on the side of the oil storage ring, and multiple mixing impellers are evenly distributed at the end of the mixing column that extends into the oil storage ring.

[0022] By adopting the above technical solution, the rotation of the mixing column on the oil storage ring can be used to mix the oil inside the oil storage ring by the mixing impeller, thus preventing the oil from separating.

[0023] Compared with the prior art, the beneficial effects of the present invention are: the graphite boat automated installation and calibration machine can easily adapt to the screwing of nuts of different sizes, and can tighten the bolt when screwing the nut to prevent the bolt and nut from rotating synchronously, and can lubricate the surface of the bolt when screwing the nut to improve the smoothness of screwing the nut on the bolt. 1. Equipped with a pressure rod, when the tension rod needs to tighten or loosen the nut, the pressure rod first contacts and presses against the end of the bolt to prevent the bolt from rotating when the nut is turned later. After being stressed, the pressure rod moves inward toward the guide column. This movement of the pressure rod into the guide column allows the internal airflow to be introduced into the clamping column through the air supply hose. The increased airflow inside the clamping column pushes the connecting rod inward toward the tension rod. By sliding the fixing column on the connecting rod, nuts of different sizes can be clamped. 2. A fixed column is provided. When the fixed column clamps the nut, it moves inside the oil storage chamber. The movement of the fixed column can spray the oil inside the oil storage chamber onto the thread of the bolt through the oil spray pipe, thereby lubricating the thread. At the same time, after the fixed column is reset, the oil storage chamber can draw the oil from the oil storage ring through the oil suction pipe for the next lubrication. 3. Equipped with a plunger, the guide column moves the side block, which in turn moves the plunger synchronously. The movement of the plunger causes the end block to move in the spiral drive groove. The movement of the end block causes the mixing column to rotate. The rotation of the end of the mixing column inside the oil storage ring agitates the oil inside the oil storage ring, preventing the oil from separating. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1: Please refer to Figures 1-8 When using existing calibration devices, the tightening mechanism on the device can only adapt to nuts of a certain size. When the size of nuts on different graphite boats is different, the tightening mechanism cannot be adapted to the nuts. At the same time, when tightening the nuts, it is not convenient to tighten the bolts, which can easily cause the bolts and nuts to rotate synchronously. In order to solve this technical problem, this embodiment discloses the following technical content. An automated graphite boat installation and calibration machine includes a connecting frame 1, a support base 2 fixedly connected to the middle of the connecting frame 1, a positioning frame 3 installed on the front side of the upper end of the support base 2, a movable frame 4 installed on the rear side of the upper end of the support base 2, and the lower end of the movable frame 4 connected to the telescopic end of the limiting cylinder 5; guide rails 6 are installed on the front and rear sides of the support base 2, and a movable seat 7 is installed on the guide rails 6, a lifting frame 8 is installed on the movable seat 7, and an adjusting cylinder 9 is fixedly connected to the side of the lifting frame 8. The telescopic end of the adjusting cylinder 9 is fixed to the guide seat 10, and a laser sensor 11 is installed on the guide seat 10. A servo motor 12 is fixedly connected to the side of the guide seat 10, and a tensioning rod 13 for tightening nuts is connected to the output end of the servo motor 12. A regulating lubrication component is installed on the tensioning rod 13 for pressing the bolt against the bolt and spraying oil to lubricate the surface threads of the bolt. The positioning frame 3 and the movable frame 4 are symmetrically arranged about the transverse central axis of the support base 2, and the movable frame 4 and the support base 2 are slidably connected. The lubrication control component includes a pressure rod 14, which is located in the middle of the tension rod 13. The pressure rod 14 is inserted into the interior of the guide post 141, and is connected to the interior of the guide post 141 via an auxiliary spring 142. The guide post 141 is connected to the interior of the tension rod 13 via a return spring 143. The interior of the guide post 141 is connected to the locking post 145 via an air supply hose 144, and the locking post 145 is fixed to the side of the tension rod 13. A connecting rod 146 is installed on the side of the connector 145, and one side of the connecting rod 146 is inserted into the interior of the locking post 145. A fixing post 147 is installed in the middle of the connecting rod 146, and the fixing post 147 is connected to the interior of the connecting rod 146 through a built-in spring 148. The surface of the end of the pressure rod 14 extending out of the guide post 141 is roughened, and the end of the pressure rod 14 extending into the interior of the guide post 141 forms a seamless sliding connection structure with the guide post 141 through a circumferentially fixed sealing ring. The airflow in the internal cavity of the guide post 141 is interconnected with the airflow in the internal cavity of the locking post 145 through the air supply hose 144, and the interior of the locking post 145 is set as a hollow structure, allowing the connecting rod 146 to slide on the locking post 145.

[0028] When the graphite boat needs to be calibrated, it is clamped and transferred to the support base 2 by a robotic arm and other components. Then, the movable frame 4 moves on the support base 2 by opening the limit cylinder 5. The movement of the movable frame 4 fixes the graphite boat between the movable frame 4 and the positioning frame 3. Then, the position of the laser sensor 11 on the guide seat 10 is changed by sliding the movable seat 7 on the guide rail 6. The laser sensor 11 realizes multi-point detection. The linear distance between itself and the detection point is detected by two opposing laser sensors 11, thereby realizing the calibration of the graphite boat. When the nut needs to be tightened or loosened during the detection process, the cylinder 9 is adjusted so that the tightening rod 13 is close to the nut. At this time, the pressure rod 14 in the middle of the tightening rod 13 first abuts against the end of the bolt. The bolt is tightened by the pressure rod 14 to prevent the bolt from rotating synchronously with the nut. After the pressure rod 14 is subjected to force, it can first slide synchronously with the guide post 141 inside the tension rod 13. When the guide post 141 moves to the limit position, the pressure rod 14 will move on the guide post 141 after being pressed. The movement of the pressure rod 14 can squeeze the airflow inside the guide post 141 through the air supply hose 144 to the inside of the clamping post 145. As the airflow inside the clamping post 145 increases, it can push the docking rod 146 to move inward towards the inside of the tension rod 13. At this time, the fixing post 147 on the docking rod 146 moves on the docking rod 146, thereby using the fixing post 147 to clamp the nut. The fixing post 147 can slide on the fixing post 147, so as to adapt to the fixing of nuts of different sizes.

[0029] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. When tightening the nut, it is inconvenient to lubricate the threads on the bolt. When the bolt surface is covered with dirt or rust, there is significant resistance between the nut and the bolt. Forcibly tightening the nut using the tightening mechanism can easily damage the threads. To further solve this technical problem, this example discloses the following technical content: Figures 3-9 As shown; One end of the fixed post 147 extends into the interior of the connecting rod 146, forming an oil storage chamber 149 with the interior of the connecting rod 146. An injection pipe 1410 is installed on the side of the oil storage chamber 149. The oil storage chamber 149 is interconnected via an oil suction pipe 1411 and an oil reservoir ring 1412. Both the injection pipe 1410 and the oil suction pipe 1411 are equipped with one-way valves. The oil reservoir ring 1412 is fixed to the tensioning rod 13. A lateral guide is fixedly connected to the side of the end of the guide post 141. Block 1413, and a rod 1414 is fixedly installed on the side block 1413. The rod 1414 is inserted into the interior of the mixing column 1415, and the mixing column 1415 is mounted on the side of the oil reservoir ring 1412 via a bearing. A locking block 1416 is fixedly connected to the side of the end of the rod 1414 that extends into the interior of the mixing column 1415, and the locking block 1416 is inserted into the interior of the drive groove 1417, which is opened inside the mixing column 1415. The end of the fixed column 147 forms a seamless sliding connection structure with the oil storage chamber 149 inside the docking rod 146 through a fixed sealing ring, and the fixed column 147 and the docking rod 146 are symmetrically arranged about the transverse central axis of the tensioning rod 13. The side edges of the lateral block 1413 and the guide post 141 are welded together, and the lateral block 1413 and the guide post 141 can slide on the tensioning rod 13. The lateral block 1413 and the insertion rod 1414 are vertically distributed. The outer wall of the locking block 1416 at the end of the insertion rod 1414 and the inner wall of the drive groove 1417 are in contact with each other, and the drive groove 1417 is set with a spiral structure. The mixing column 1415 can rotate on the side of the oil storage ring 1412, and multiple mixing impellers are evenly distributed at the end of the mixing column 1415 that extends into the oil storage ring 1412.

[0030] After the pressure rod 14 moves, the guide post 141 can move inside the tension rod 13. The movement of the guide post 141 causes the side block 1413 to drive the insertion rod 1414 to move synchronously. The movement of the insertion rod 1414 allows the end block 1416 to slide inside the spiral drive groove 1417, thus allowing the mixing column 1415 to rotate inside the oil reservoir ring 1412. The rotation of the mixing column 1415 utilizes its mixing impeller to agitate the oil inside the oil reservoir ring 1412, ensuring uniform oil distribution and preventing oil stratification that could result in oil being sprayed onto the threads and affecting the overall lubrication effect. When the guide post 141 moves to its limit, the pressure rod 141 moves within the tension rod 13. When the internal movement of 41 occurs, the fixing post 147 and the connecting rod 146 can move inward toward the tensioning rod 13, thereby limiting the nut. After the fixing post 147 moves in the oil storage chamber 149 inside the connecting rod 146, it can spray the oil inside the oil storage chamber 149 onto the thread of the bolt through the oil spray pipe 1410, thereby lubricating the thread and reducing the resistance encountered by the nut during subsequent tightening. After the nut is tightened, the fixing post 147 is disengaged from the nut and reset by the built-in spring 148. At this time, after the fixing post 147 is reset inside the oil storage chamber 149, the oil storage chamber 149 can again draw oil from the oil storage ring 1412 through the oil suction pipe 1411, so as to lubricate the next bolt.
