Abstract
Description
Technical Field
[0001] This utility model relates to the field of instrumentation and testing technology, specifically a testing device for chemical instruments. Background Technology
[0002] Chemical instrumentation plays a crucial role in modern chemical production, monitoring and controlling various process parameters such as pressure, temperature, and flow rate. The accuracy and reliability of these instruments directly affect the efficiency, safety, and product quality of chemical production. Therefore, rigorous testing of the instruments is an essential step in the manufacturing process of chemical instruments.
[0003] Traditional chemical instrument testing typically relies on manual operation. This involves manually placing the instrument at the testing location, connecting and testing it, and then removing it after testing. This manual approach is not only inefficient but also prone to human error, affecting the accuracy of test results. During manual operation, it's difficult to ensure that testing conditions are completely consistent each time; parameters such as the pressure application rate and testing time may vary depending on the operator. This lack of standardization can lead to inconsistent test results, affecting the accurate assessment of instrument quality. Furthermore, manual operation makes real-time monitoring and recording of the testing process difficult, hindering subsequent quality traceability and analysis.
[0004] After testing, qualified instruments proceed to the next process, while unqualified instruments are recycled for repair or scrapped. Traditionally, the sorting and recycling of qualified and unqualified products is done manually, which not only increases the number of steps but also easily leads to sorting errors, causing qualified and unqualified products to be mixed up.
[0005] The lack of an automated recycling mechanism also affects the continuity of the entire testing process, which is not conducive to the automation and intelligence of the production process.
[0006] Chemical instrumentation testing may involve hazardous conditions such as high pressure and high temperature, posing a significant safety risk to operators during manual operation. Improper operation could lead to accidents and threaten the personal safety of the operators.
[0007] Traditional testing equipment is often not designed with sufficient consideration for the safety of operators, and lacks necessary safety devices and early warning mechanisms. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it. The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.
[0026] See Figures 1 to 4 This embodiment proposes a testing device for chemical instruments, including a device body 1, a fixing mechanism 3, a testing mechanism 2, a feeding mechanism 4, and a conveyor belt 5. A recovery channel 18 is located at the top center of the device body 1. Fixing mechanisms 3 are installed on the left and right sides of the upper end of the recovery channel 18 to clamp chemical instruments. The testing mechanism 2 is located at the top of the device body 1 and behind the recovery channel 18. After the fixing mechanism 3 fixes the chemical instrument, the testing mechanism 2 moves forward and connects with the chemical instrument to perform testing. The conveyor belt 5 is located on one side of the device body 1 and simultaneously in front of the recovery channel 18, transporting the chemical instrument to a designated location. The feeding mechanism 4 is located between the conveyor belt 5 and the fixing mechanism 3. The feeding mechanism 4 transfers the chemical instrument from the conveyor belt 5 to the fixing mechanism 3 for testing, and transfers qualified chemical instruments from the fixing mechanism 3 back onto the conveyor belt 5.
[0027] Specifically, the fixing mechanism 3 includes cylinder 2 17, which are symmetrically arranged on the left and right sides of the recovery channel 18. The adjacent end of the two cylinders 2 17 is the driving end of cylinder 2 17, and a clamping plate 16 is fixedly provided on the driving end of cylinder 2 17. The surface of the clamping plate 16 is provided with an arc-shaped instrument body placement groove and a semi-circular groove for the instrument connecting pipe head on one side. The chemical instrument can be firmly fixed by the two mating instrument body placement grooves. After the two instrument connecting pipe head semi-circular grooves are mated, the testing mechanism 2 can be easily inserted to connect with the chemical instrument.
[0028] The testing mechanism 2 includes a pressure testing connector 19, which corresponds to the semi-circular groove of the instrument connector. The pressure testing connector 19 is connected to the pressurization pump 22 via a flexible pipe. The pressurization pump 22 is mounted on the device body 1. The pressure testing connector 19 is connected to a moving mechanism, which drives the pressure testing connector 19 to move towards or away from the recovery channel 18.
[0029] The moving mechanism includes an internally threaded mounting block 20, a lead screw 21, and a motor 23; the pressure test connector 19 is fixedly provided with internally threaded mounting blocks 20 on both sides, and the lead screw 21 is internally threadedly connected to the internally threaded mounting block 20, which is driven by the motor 23. The lead screw 21 is rotatably connected to the device body 1.
[0030] The feeding mechanism 4 includes a stepper motor 7, a rotating shaft 8, a rotating plate 9, a cylinder 10, and a suction cup 11. The rotating shaft 8 is rotatably connected to the device body 1, and its bottom end is connected to the stepper motor 7. The rotating plate 9 is fixedly mounted on the upper end of the rotating shaft 8, and cylinders 10 are fixedly mounted on the lower ends of both sides of the rotating plate 9. The driving ends of cylinders 10 face downwards, and suction cups 11 are fixedly mounted on the driving ends of cylinders 10. The rotation radius of the suction cups 11 is respectively set to correspond to the clamping plate 16 and the conveyor belt 5.
[0031] The device body 1 is hinged to a switch door 6. Inside the device body 1 are air pump 12, air pump 2 15, vacuum pump 13 and recovery box 14. The recovery box 14 is vertically connected to the recovery channel 18. Vacuum pump 13 and suction cup 11 are driven by a pipe. Cylinder 10 is driven by air pump 12, and cylinder 2 17 is driven by air pump 2 15.
[0032] The working principle of the chemical instrument testing device proposed in this embodiment is as follows: The chemical instrument to be tested is transported to a designated position on one side of the device body 1 via conveyor belt 5. Stepper motor 7 is started, driving rotating shaft 8 to rotate, thereby rotating rotating plate 9. This causes cylinder 10 and suction cup 11 on one side of rotating plate 9 to move above conveyor belt 5. Cylinder 10 extends and retracts downward under the drive of air pump 12, causing suction cup 11 to contact the chemical instrument on conveyor belt 5. Suction cup 11 generates suction under the action of vacuum pump 13, adsorbing the chemical instrument.
[0033] Stepper motor 7 starts again, rotating plate 9 moves suction cup 11 with chemical instrument attached to it above clamping plate 16; cylinder 10 extends and retracts downward, transferring the chemical instrument from suction cup 11 to the arc-shaped instrument body placement slot of clamping plate 16; cylinder 2 17 extends and retracts inward under the drive of air pump 2 15, clamping surface on clamping plate 16 clamps and fixes the chemical instrument, keeping it stable during testing and preventing displacement or damage to the instrument due to pressure or other factors.
[0034] The pressure test connector 19 moves under the drive of the motor 23 through the cooperation of the internal thread mounting block 20 and the lead screw 21, so that the pressure test connector 19 is tightly connected to the instrument connector of the chemical instrument; the pressure test connector 19 is connected to the pressure pump 22 through the flexible pipe, the pressure pump 22 starts to work, and applies pressure to the inside of the chemical instrument to carry out the pressure test.
[0035] During the test, the device and external detection and control devices monitor and record parameters such as test pressure and time. If the chemical instrument can withstand the specified pressure and there are no abnormalities such as leakage during the test, it is judged as qualified. If leakage, damage or other non-compliance occurs, it is judged as unqualified.
[0036] For chemical instruments that pass the test, cylinder 17 extends and retracts outward under the drive of pump 15, and clamping plate 16 releases the chemical instruments; stepper motor 7 starts, and rotating plate 9 rotates, causing cylinder 10 and suction cup 11 on the other side of rotating plate 9 to move above clamping plate 16. Cylinder 10 extends and retracts downward, and suction cup 11 generates suction under the action of vacuum pump 13, adsorbing the qualified chemical instruments; then cylinder 10 extends and retracts upward to lift the chemical instruments, stepper motor 7 starts again, rotating plate 9 moves the chemical instruments above conveyor belt 5, cylinder 10 extends and retracts downward to put the qualified chemical instruments back on conveyor belt 5, and continue to transport them to the next process; Unqualified instruments are recycled to the recycling bin: When the cylinder 17 extends and retracts outward under the drive of the air pump 15, and the clamping plate 16 is released, the chemical instrument will fall directly into the recycling channel 18 due to its own gravity, and then fall into the recycling bin 14 along the recycling channel 18 for recycling.
[0037] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments. It should not be considered that the specific embodiments of the present invention are limited to this. For those skilled in the art, several simple deductions or substitutions can be made without departing from the present invention, and all such deductions or substitutions should be considered to fall within the scope of patent protection determined by the submitted claims.
