Description

Technical Field

[0001] The invention relates to the technical field of detection equipment, in particular to a full-automatic pressure testing machine. Background Art

[0002] A pressure testing machine is a test device used to evaluate the performance of materials or products under specific pressure conditions. It is widely used in industrial production, construction, automobiles, aerospace and other fields. Its main function is to apply a certain pressure to the object to be tested to detect its physical properties under static or dynamic stress, such as strength, hardness, durability, etc. Through pressure testing, it can be determined whether the material or product meets the design requirements and ensure its safety and reliability in actual use. Existing pressure testing machines are usually composed of test cabinets, pressure loading devices, sensor systems and other parts, which can perform standard pressure loading and data recording. After the operator places the object to be tested in the specified position, the equipment will apply pressure to it according to the preset pressure curve and collect relevant data through sensors. The test results can be used to evaluate the load-bearing capacity, deformation performance and failure point of the object, etc., to help manufacturers optimize product design and improve material performance. Although traditional pressure testing machines have basic pressure testing functions, their degree of automation is low and they mainly rely on manual operation to load, test and record the results of the sample blocks, so some problems will still be encountered in actual use.

[0003] First, when the traditional pressure testing machine is in operation, various mechanical parts (such as hydraulic cylinders, push plates, etc.) work continuously for a long time, which is prone to increased friction and component wear. Due to the lack of automated lubrication and cleaning systems, the maintenance cycle of the equipment is short, and the stability of the equipment operation is difficult to guarantee. Especially in long-term and high-intensity tests, the equipment often needs to be frequently shut down for lubrication and cleaning, which not only increases maintenance costs, but also affects production efficiency;

[0004] Secondly, in the existing equipment, the docking between the transport trolley used in the process of transporting and testing the specimen block and the test machine is often unstable. Due to the imperfect design of the docking system, the docking between the transport trolley and the test cabinet usually relies on manual adjustment or simple mechanical connection, lacking effective buffer devices and reliable locking mechanisms. During docking, there are often docking position deviations or unstable specimen blocks, which causes the specimen block position to shift during the test, thereby affecting the accuracy of the test data. In addition, the impact force during docking may also cause damage to mechanical parts or reduce the accuracy, further exacerbating the wear problem of the equipment;

[0005] Finally, the existing pressure testing machines are mostly manually operated in the judgment and sorting of test results. After the test is completed, the quality of the sample blocks needs to be manually judged and qualified products and defective products are manually classified. Due to subjective errors in manual sorting, it is easy to cause wrong judgments and reduce the accuracy of sorting. At the same time, manual sorting efficiency is low, especially in scenarios where a large number of sample blocks need to be processed continuously. Classification delays or confusion are prone to occur, affecting the overall efficiency of the production line. Summary of the invention

[0021] Preferably, two placement rooms are provided on the other side of the partition wall, one placement room is used to store sample blocks to be tested, and the other placement room is used to store sample blocks that have been tested. A push plate door is provided on one side of each placement room, and a partition door is provided inside the placement room. The partition door is used to separate the humidity environment and the dry environment inside the placement room. A plurality of shelves distributed in a rectangular array are provided in the high humidity environment space divided by the partition door of the placement room, and a robotic arm three is provided between the shelves.

[0022] Preferably, a PLC module is provided inside the partition wall, a second motor is provided inside the partition wall, the PLC module and the second motor are electrically connected, and a second cylinder is fixed to the output end of the second motor.

[0023] Preferably, the PLC module is internally provided with a receiving module, a driving module and a rate control module;

[0024] The receiving module is used to receive the sample block information detected by the test cabinet and determine whether the sample block is qualified;

[0025] The driving module is used to control the cylinder 2 according to the qualified information of the sample block received through the test cabinet to finally transport the sample block to the finished product area or the defective product area;

[0026] The rate control module is used to automatically control the speed of the sample block conveyed by the cylinder 2 driving speed according to the conveying speed of the conveyor belt and the identification structure of the test cabinet.

[0027] Working principle: When the equipment is in operation, the sample block will first be taken out from the indoor shelf where the sample block to be tested is placed by the conveyor trolley using a mechanical arm for transportation. The conveyor trolley will open the push-plate door, and then transport the sample block to the test area, which is the area within the fence relative to the central console, and under the restriction of the limit frame, the position of its docking rod 1 is connected to the position of the docking rod 2 of the docking frame. During docking, the docking rod 1 will hit the buffer plate to buffer the impact force. At the same time, after docking, the motor 1 will drive the docking rod 1 to rotate, and then control the corresponding ball to reach the appropriate slot in the docking rod 2, and dock with the docking plate. The docking plate is squeezed to provide the central console with information that the conveyor trolley is in place. When the docking rod 1 is docked with the docking rod 2, the corresponding The ball will first be acted upon by the force and then squeeze the spring through the slider. At this time, the magnetic block 1 will also slide along the limit column, so that the docking rod 1 and the docking rod 2 can successfully survive the catastrophe. When the ball is successfully docked with the slot, the spring cooperates with the repulsive force between the magnetic block 2 and the magnetic block 1 through its own restoring property, so that the slider can smoothly engage the ball under the dual push of the spring and the magnetic block 1. After the conveyor trolley is in place, the number of sample blocks on the conveyor trolley will be identified through the identification frame, and the robot arm will be driven to start carrying at the beginning. Before carrying, the robot arm 1 will scan the item information of the sample block through the camera at the claw end, and then transport it to the measuring mechanism between the test cabinets to measure the length, width, height, the angle between the two surfaces and the test The flatness of the sample block is checked, and then the robot arm 1 is used to place the sample block into the corresponding test cabinet for pressure testing. The position of the sample block has been adjusted when the robot arm 1 is placed. After the adjustment is completed, the hydraulic cylinder can be driven to perform pressure testing. In order to ensure the accuracy after the test is completed, the push plate is driven to pull to the rear side by the cylinder 1. At this time, the debris remaining on the equipment will be pushed to the conveyor belt position by the rubber strip at the push plate position, and then transported away. While sliding through the limit block, the corresponding piston will also slide in the cylinder. When the piston slides into the cylinder, it will pass the lubricating oil stored in the cylinder through the swivel of the solenoid valve and transport it to the inside of the hydraulic cylinder through the delivery pipe 1 to keep the hydraulic cylinder lubricated. When sliding outward, the corresponding solenoid valve will switch the pipeline connected to the corresponding air cylinder position to the conveying pipe 2, so that it can extract new lubricating oil from the lubricating oil barrel for backup. Finally, the sample block that has completed the pressure test will be transmitted to the conveyor belt in front of the test cabinet through the test cabinet, and then to another conveyor belt. When passing through the partition wall, it will begin to distinguish between finished products and defective products. The finished product will receive a signal from the PLC module to drive the motor 2 to control the cylinder 2 to push it to the finished product area on the right side of the conveyor belt, and then transport it to the conveyor trolley for loading. Otherwise, it will be controlled by the cylinder 2 to fall into the waste area set on the left. After that, the conveyor trolley will automatically load the intact sample blocks in the finished product area through the robot arm 2, and then transport it., the push plate door is pushed open by the transport trolley, and then the sample block is placed in the humid environment part of the storage room for maintenance through the partition door. The trolley will leave after unloading, and then the robot arm 3 in the humid area will place the sample blocks one by one to the corresponding shelf positions. When taking the sample blocks in the storage room for testing, the robot arm 3 is also required to first move the sample blocks from the shelf position, and then quickly load them by the trolley. Usually, the trolley will stay in the drier environment area separated by the partition door.

[0028] The present invention provides a fully automatic pressure testing machine. It has the following beneficial effects:

[0029] 1. The present invention realizes automatic lubrication of the hydraulic cylinder and other moving parts by arranging components such as air cylinders, solenoid valves and lubricating oil barrels, ensuring that the equipment maintains a good operating state during long-term operation. At the same time, the coordinated work of the cleaning system inside the test cabinet can efficiently remove the debris generated during the test, ensuring the cleanliness and operating accuracy of the equipment and extending the service life of the equipment.

[0030] 2. The present invention ensures reliable locking during docking through the cooperation of the ball, slider and spring in the snap-fit ​​design, avoiding dislocation or loosening during the docking process. This system not only improves the stability and safety of docking, but also enhances the accuracy and reliability of equipment operation, ensuring smooth transmission of sample blocks.

[0031] 3. The present invention, through the control of the PLC module and the second cylinder, can automatically sort the sample blocks to the finished product conveying trolley position or directly convey them to the defective product area by the conveyor belt according to the pressure test results in the test cabinet. The linkage design of the conveyor belt and the second cylinder makes the sorting process accurate and efficient, avoids human intervention, improves production efficiency and sorting accuracy, and ensures strict distinction between finished products and defective products.

[0042] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Please refer to the attached Figure 1 , an embodiment of the present invention provides a fully automatic pressure testing machine, comprising:

[0044] A test cabinet 1, which is used to perform pressure testing on items, and a partition wall 8 is provided on one side of the test cabinet 1;

[0045] A transport trolley 2, which is arranged on both sides of the test cabinet 1 and is used to transport the sample block 24;

[0046] An identification rack 3, which is arranged on one side of the conveying trolley 2, and is used to inspect the position and quantity of the sample blocks 24 conveyed by the conveying trolley 2;

[0047] A conveyor belt 4, which is arranged at one side of the test cabinet 1 and is divided into two sections, and is used to convey the sample block 24 measured by the test cabinet 1 out;

[0048] A mechanical arm 5, which is arranged between the conveying trolleys 2, is used to scan and identify the sample block 24 and transport it to the position of the test cabinet 1;

[0049] A docking frame 6, which is installed on one side of the conveying trolley 2, is used to dock the docking frame 6 and fix its position;

[0050] The central control console 7 is installed on the side of the test cabinet 1 close to the conveying trolley 2 and is used to control the overall operation process.

[0051] Specifically, the test cabinet 1 is used to perform pressure tests on items, the conveyor trolley 2 is responsible for moving on both sides of the test cabinet 1 to transport the sample blocks 24 to the test position, the identification frame 3 is responsible for detecting the placement and quantity of the sample blocks 24 on the conveyor trolley 2, and the tested sample blocks 24 will be transported out through the conveyor belt 4, the robot arm 5 is used to identify the sample blocks 24 and move them to the test cabinet 1 for pressure testing, the docking frame 6 docks with one side of the conveyor trolley 2 to ensure that the conveyor trolley 2 is accurately positioned, and the entire operation process is managed and controlled by the central control console 7 to ensure the coordinated operation of all parts of the equipment. The docking frame 6 is placed to place abnormal sample blocks 24 detected before the pressure test, such as sample blocks 24 with missing corners and sample blocks 24 whose QR codes are not recognized by the camera on the robot.

[0052] Please see attached Figure 2 -Attached Figure 4 A hydraulic cylinder 9 is installed on the top of the inner wall of the test cabinet 1, and a cylinder 10 is installed on the bottom of the inner wall of the test cabinet 1. A push plate 11 is fixed to the output end of the cylinder 10. Limit blocks 14 are arranged on both sides of the push plate 11. The limit blocks 14 slide inside the test cabinet 1. A piston 12 is fixed to one side of the limit block 14. A gas cylinder 13 is fixed inside the test cabinet 1. The piston 12 is slidably connected to the inside of the gas cylinder 13. A solenoid valve 16 is arranged on one side of the gas cylinder 13. A delivery pipe 17 and a delivery pipe 17 are fixed to the output end of the solenoid valve 16. 18, one end of the delivery pipe 17 passes through the test cabinet 1 and is connected to the hydraulic cylinder 9, a lubricating oil barrel 19 is fixed to one end of the delivery pipe 18, the lubricating oil barrel 19 is installed inside the test cabinet 1, a measuring mechanism 20 is installed between the test cabinets 1, a driving base 22 is arranged on the top of the measuring mechanism 20, a storage platform 23 is fixedly connected to the output end of the driving base 22, two binocular cameras 21 are arranged on the inner wall of the measuring mechanism 20, the binocular cameras 21 are used to measure the sample block 24 through the height difference.

[0053] Specifically, before the pressure test of the sample block 24 is carried out, we will first use the robot arm 5 to take the sample block 24 and place it in the measuring mechanism 20 between the two test cabinets 1. At this time, the measuring mechanism 20 measures the data of the sample block 24 through the binocular camera 21 in conjunction with the surrounding lights, and at the same time, the driving base 22 can also drive the cabinet storage platform 23 to rotate and drive the sample block 24 to rotate for all-round measurement. After that, the sample block 24 is taken away by the robot arm 5 and placed in the best test position in the test cabinet 1. This position adjustment process is intended to ensure the precise positioning of the sample block 24. It can withstand the uniform pressure applied by the hydraulic cylinder 9 to ensure the effectiveness of the test and the accuracy of the data; after the position adjustment is completed, the hydraulic cylinder 9 starts to move and performs a pressure test on the sample block 24. In order to ensure the data accuracy during the test, the system starts the cylinder 10 after the test to move the push plate 11 backward to restore the initial position. At the same time, when the push plate 11 is displaced, the accompanying rubber strip produces synchronous movement, which can clean the debris to the conveyor belt 4 for transportation. This clean design ensures that the operating environment of the equipment remains clean after each test, thereby extending the equipment. The service life of the hydraulic cylinder 9 is prolonged and the safety of operation is improved. At the same time, during the sliding of the limit block 14, the piston 12 also slides synchronously in the cylinder 13. In particular, during the sliding of the piston 12 into the cylinder 13, the lubricating oil stored in the cylinder 13 is guided through the delivery pipe 17 to be delivered to the inside of the hydraulic cylinder 9 through the precise control of the solenoid valve 16. This process effectively ensures the lubrication state of the hydraulic cylinder 9, making it run more smoothly during the pressure application process, further improving the accuracy of the test and the durability of the equipment. When the piston 12 slides out of the cylinder 13, the solenoid valve 16 will automatically switch the delivery channel to deliver the lubricating oil to the cylinder 9. The delivery is switched from delivery pipe 17 to delivery pipe 2 18. At this time, the lubricating oil will be extracted from the lubricating oil barrel 19 to prepare for the next operation cycle. The design of this lubrication system ensures the long-term stable operation of the equipment, avoids the mechanical wear problem caused by lack of lubrication, and greatly reduces the maintenance cost. In summary, the present invention realizes a pressure testing process with a high degree of automation, reliable test accuracy and excellent cleaning effect through the coordinated work of multiple mechanical and control systems. This automated design not only improves the working efficiency of the equipment, but also greatly improves the durability of the equipment and the convenience of operation.

[0054] Please refer to the attached Figure 5 -Attached Figure 7The sample block 24 is arranged on the top of the conveying trolley 2, a mechanical arm 242 is fixed on one side of the conveying trolley 2, and a limit frame 25 is installed on both sides of the conveying trolley 2. A motor 26 is arranged inside the conveying trolley 2, and a docking rod 27 is fixed on the output end of the motor 26. A docking rod 28 is arranged on one side of the docking frame 6. The docking rod 27 slides inside the docking rod 28, and a buffer plate 29 is arranged inside the docking rod 28. The buffer plate 29 contacts the docking rod 27, and a fixed Column 30, the outer wall of the fixed column 30 is sleeved with a spring 31, one end of the spring 31 is fixed inside the docking rod 27, and a slider 32 is fixed to the other end of the spring 31. A ball 33 is set on one side of the slider 32, and a docking plate 34 is fixed inside the docking rod 28. The slider 32 and the docking plate 34 are in contact with each other. A magnet 35 is fixed to the outer wall of the slider 32, and the magnet 35 is slidably connected to the limiting column 36. A magnet 2 37 is fixed to the outer wall of the limiting column 36, and the magnet 1 35 and the magnet 2 37 repel each other magnetically.

[0055] Specifically, the transport trolley 2 first transports the sample block 24 to the specified position. During this process, the role of the limit frame 25 is to ensure that the sample block 24 remains stable during transportation and prevent position displacement, thereby ensuring that the sample block 24 can be accurately docked. Through the limiting effect of the limit frame 25, the sample block 24 is maintained in an ideal state, and the docking rod 1 27 and the docking rod 2 28 on the docking frame 6 can be accurately docked. At this time, the docking rod 1 27 will inevitably generate a certain impact force during the movement. In order to eliminate the potential impact of this impact on the equipment and the sample block 24, the system is designed with a buffer plate 29, which can effectively absorb the impact force, thereby achieving buffering protection for the entire docking process, ensuring that the equipment is While operating efficiently, it avoids damage caused by mechanical impact; after the docking rod 1 27 and the docking rod 2 28 are successfully docked, the motor 1 26 will start and drive the docking rod 1 27 to rotate accurately. The purpose of this rotation is to move the ball 33 to the appropriate slot inside the docking rod 28 to achieve stable mechanical engagement. Through this design, the equipment can ensure the firmness of the docking and avoid looseness or misalignment in subsequent operations, thereby improving the overall reliability of the equipment; during the docking process, the docking plate 34 will also be compressed and provide a signal to the central console 7 to confirm that the conveying trolley 2 is accurately in place. The transmission of this signal is an important part of the internal coordination of the equipment, ensuring the accuracy and timeliness of subsequent operations. 2 After successful docking and providing the positioning signal, the other parts of the equipment will continue to operate, thereby realizing the orderly operation of the entire system; when the docking rod 1 27 and the docking rod 2 28 are docked, the ball 33 will first be acted upon by the external force, prompting it to move along the slide rail. At this time, the slider 32 squeezes the spring 31 by the force, causing the spring 31 to deform to adapt to the slight adjustment and dynamic changes during docking. This design ensures the smooth docking process and avoids docking failure caused by the mismatch between the card slot and the ball 33 position; at the same time, the magnetic block 1 35 slides along the limit column 36 during the docking process, further ensuring that the docking rod 1 27 and the docking rod 2 28 can be docked smoothly. Through this sliding design, the device can better adapt to In order to cope with the changes in the docking process and avoid poor docking caused by minor errors in the docking process, the smooth transition of this step makes the operation of the docking rod more stable; when the ball 33 is successfully inserted into the slot, the spring 31 relies on its own restorability to recover to the initial state. At this time, the repulsive force between the second magnetic block 37 and the first magnetic block 35 further pushes the slider 32 back to its original position. This dual driving force design through the interaction of the spring 31 and the magnetism ensures the stable engagement of the ball 33 and makes the entire docking process smooth, precise and efficient. This design not only ensures the efficient operation of the equipment, but also minimizes mechanical wear and the impact on the life of the equipment, thereby extending the service life of the equipment and improving the overall performance of the equipment.

[0056] Please see attached Fig. 9 Two placement chambers 41 are arranged on the other side of the partition wall 8, one placement chamber 41 is used to store the sample blocks 24 to be tested, and the other placement chamber 41 is used to store the sample blocks 24 after testing. A push plate door 43 is arranged on one side of the placement chamber 41, and a partition door 44 is arranged inside the placement chamber 41. The partition door 44 is used to separate the humidity environment and the dry environment inside the placement chamber 41. A plurality of shelves 15 distributed in a rectangular array are arranged in the high humidity environment space divided by the partition door 44 in the placement chamber 41, and a robotic arm 45 is arranged between the shelves 15.

[0057] Specifically, a sample block 24 to be tested that is stored in a sample block 24 can be transported by the transport trolley 2 on standby inside it. In order to prevent the transport trolley 2 from getting damp, the corresponding transport trolley 2 generally stays in a non-humid area. The sample blocks 24 on the shelf 15 are first stacked on the pallet position by the mechanical arm three 45 driven by an electric slide rail, and the transport trolley 2 then passes through the position of the partition door 44 to take away the sample blocks 24 placed on the pallet position. Similarly, when stacking, the transport trolley 2 is also required to unload the sample blocks 24 on the pallet position, and then the mechanical arm three 45 performs the specific placement task on the shelf 15. When the transport trolley 2 pushes the plate door 43 and the partition door 44 back and forth, they need to be pushed open to allow the transport trolley 2 to pass smoothly.

[0058] Please see attached Figure 8 A PLC module 38 is provided inside the partition wall 8, a motor 2 39 is provided inside the partition wall 8, the PLC module 38 and the motor 2 39 are electrically connected, a cylinder 2 40 is fixed to the output end of the motor 2 39, and a receiving module, a driving module and a speed control module are provided inside the PLC module 38;

[0059] The receiving module is used to receive the information of the sample block 24 detected by the test cabinet 1 and determine whether the sample block 24 is qualified;

[0060] The driving module is used to control the cylinder 2 40 to push the sample block 24 to the finished product area or the defective product area according to the qualified information of the sample block 24 received through the test cabinet 1;

[0061] The rate control module is used to automatically control the driving speed of the cylinder 2 40 to correspond to the speed of the sample block 24 being transported according to the transport speed of the conveyor belt 4 and the identification structure of the test cabinet 1.

[0062] Specifically, after the pressure test is completed, the sample block 24 will be transferred to the conveyor belt 4 by the mechanical device in the test cabinet 1. The transfer in this process is not only rapid but also smooth, ensuring that the sample block 24 will not be damaged due to excessive movement speed or vibration during the transmission process. The conveyor belt 4 is designed as a two-stage structure. The first section of the conveyor belt 4 transfers the sample block 24 from the test cabinet 1 to the sorting area of ​​the equipment, while the second section of the conveyor belt 4 is responsible for further transferring the sample block 24 to the final sorting area; when the sample block 24 passes through the partition wall 8, the sorting process officially begins. The intelligent control module of the equipment is integrated inside the partition wall 8, which can automatically perform a preliminary judgment on the quality inspection of the sample block 24 based on the test results recorded in the test cabinet 1. After the sample block 24 passes through the partition wall 8, the PLC module 38 receives the data from the test machine, and comprehensively judges whether the sample block 24 meets the set quality standards based on its performance in the pressure test. The module can accurately identify the quality of the sample block 24 through a highly intelligent algorithm. state, ensuring the accuracy of sorting; once the judgment is completed, the PLC module 38 will send an instruction to the control system to drive the second motor 39 to start. The second motor 39 is connected to the second cylinder 40 in the sorting system. The main function of the second cylinder 40 is to push the sample block 24 to different areas according to the judgment of the PLC module 38. For the finished products that have passed the inspection, the second cylinder 40 will be accurately controlled to make the sample block 24 slide smoothly onto the conveying trolley 2 on the right side of the conveyor belt 4. This process is extremely accurate and can ensure that the finished products maintain their original state throughout the sorting process to avoid unnecessary collisions or secondary damage; on the other hand, if the PLC module 38 determines that the sample block 24 is an unqualified product, that is, a defective product, the second motor 39 will adjust the angle of the second cylinder 40 to push the sample block 24 to the left side of the conveyor belt 4, and make it fall into the waste area at the end of the left side through transmission. This action is fast and stable, which can ensure that the defective products will not be confused with the finished products during the sorting process, avoiding affecting the subsequent classification and processing work.
