Description

Technical Field

[0001] The present invention relates to the technical field of instrument sealing detection, in particular to a sealing detection device and a method for detecting the sealing performance of an instrument. Background Art

[0002] During the production process, instruments and meters need to undergo effective sampling inspections on finished products before they can be put into subsequent use. Many instruments and meters need to overcome greater environmental pressures when in use, so it is particularly important to inspect the instrument's performance such as anti-drop, waterproof sealing, and dynamic balance.

[0003] In existing detection devices, such as Chinese patent CN116046276B, the incomplete gear and the center pulley are driven to rotate simultaneously through the central shaft. On the one hand, when the incomplete gear rotates, the water flow impacts the instrument in the detection chamber through linkage to realize forward and reverse rotation, thereby avoiding the formation of a vortex in the water flow impact detection chamber when the instrument rotates in one direction all the time. The vortex direction is consistent with the rotation direction of the instrument, and the water flow impact force of the instrument cannot be realized, thereby failing to detect the water flow impact ability and anti-fall ability of the detection instrument. On the other hand, the sealing detection rotating shaft is driven to rotate by the center pulley, so that the sealing test threaded rod drives the sealing test pressure plate to move downward, pressing down the gas and water medium in the sealing performance detection chamber to form different water pressures, thereby detecting the sealing performance of the instrument.

[0004] However, there are still the following problems: during instrument testing, workers need to grab a product individually and place it into the testing device for testing before they can test the next product. When facing the testing of a large number of products on the assembly line, the testing speed is obviously unable to adapt to the production speed of the assembly line, which can easily lead to a lag in the test results and easily cause batches of products to be unqualified. The test results cannot be adapted to the production line in real time, and the efficiency of the testing device is low. Summary of the Invention

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0035] As introduced in the background technology, in order to solve the deficiencies in the prior art and to address the above technical problems, this application proposes a sealing detection device and a method for detecting the sealing performance of an instrument.

[0036] Example 1, a typical embodiment of the present application, as Figure 1 As shown, a sealing detection device includes a body 1, an auxiliary mechanism 2 disposed in the body 1, and a detection mechanism 3 disposed in the body 1. The auxiliary mechanism 2 includes a rail frame 26 and an instrument box 211. The body 1 is provided with the rail frame 26, which passes through the body 1. Both ends of the rail frame 26 are connected to the transmission system of the production line. The rail frame 26 is used to transport the instrument box 211. After the instrument box 211 enters the body 1, it undergoes sealing detection and dynamic balance detection.

[0037] The detection mechanism 3 includes a detection component 3001, which is located below the rail frame 26. The detection component 3001 is located directly below the detection position in the body 1. After the instrument box 211 moves to the detection position, the detection component 3001 is closed onto the instrument box 211. The detection component 3001 performs a sealing detection process on the instrument box 211 and performs a dynamic balance detection process on the parts in the instrument box 211.

[0038] Furthermore, the transmission system is an existing structure, specifically a conveying system of an instrument production line, such as rail-type transmission, conveyor belt transmission, etc. The rail-type transmission method specifically used in the present invention is for transportation, but is not limited to the method specifically proposed in the present invention.

When the detection component 3001 is closed on the instrument box 211, the detection component 3001 and the instrument box 211 are sealed, and then the detection component 3001 uses airflow to blow from one side of the instrument box 211 to the other side. , and detects whether there is gas flow on the other side of the instrument box 211 to detect the sealing of the instrument box 211. At the same time, the detection component 3001 performs dynamic balance detection on the parts in the instrument box 211. Compared with the current worker-assisted single-take detection detection processing flow, the detection device can be better adapted to the instrument production line, and when defective products are found in the detection results, the transmission of the instrument to the conveying system can be directly stopped, the operation of the production line can be stopped in time, and the detection results can be synchronized with the production line, thereby improving the detection efficiency of the detection device and ensuring the quality of the production line products.

[0041] Example 2, as Figure 2-Figure 4 As shown, the difference from the above embodiment is that the auxiliary mechanism 2 also includes a slide rail 21, which is fixedly mounted on the inner wall of the body 1.

[0044] Furthermore, the rail frame 26 is divided into two parts, the two parts of the rail frame 26 are located at the same height, the distance between the two parts of the rail frame 26 is greater than the length of the instrument box 211, the rail frame 26 is adapted to the transmission system of the production line, and the two parts of the rail frame 26 are slidably matched with a moving platform 27, and the moving platform 27 moves in the same direction and speed on the rail frame 26. Screws 28 are rotatably provided on the two parts of the rail frame 26, and the length of the screw 28 is the same as the length of the rail frame 26. The screws 28 pass through the moving platform 27, and the screws 28 are threadedly matched with the moving platform 27. A clamping member 29 is movably provided on the moving platform 27, and the clamping member 29 is located between the two parts of the rail frame 26. A cylinder 210 is fixedly installed on the moving platform 27, and the cylinder 210 is power-connected to the clamping member 29 so that the clamping member 29 clamps from both sides to the middle.

[0045] Furthermore, a stepper motor is provided in the transmission system where the rail frame 26 and the screw 28 are located, and a gear set and a planetary reducer are provided between the stepper motor and the screw 28. The stepper motor is power-connected to the gear set, the gear set is power-connected to the planetary reducer, and the planetary reducer is power-connected to the screw 28, so that the stepper motor drives the screw 28 to rotate slowly and accurately, thereby controlling the movable platform 27 on the rail frame 26 to move accurately.

[0046] Furthermore, a plurality of mobile platforms 27 can be provided on the rail frame 26 , and the mobile platforms 27 are evenly distributed, that is, the plurality of mobile platforms 27 on the production line each carry the instrument box 211 for transportation, so that the production efficiency of the entire production line is fully utilized.

Then, the stepper motor in the transmission system is used to drive the gear set to run, the gear set drives the planetary reducer to run, the planetary reducer drives the screw 28 to rotate, the screw 28 drives the moving platform 27 to move on the rail frame 26, the moving platform 27 drives the clamping parts 29 to move, and the clamping parts 29 drive the instrument box 211 to move on the rail frame 26, so that the instrument box 211 moves to the detection position in the body 1.

[0048] Furthermore, an instrument box 211 is provided between the clamping parts 29, and the instrument box 211 is clamped by the clamping parts 29.

The pointer 213 is power-connected to the instrument gear assembly 212, and a docking port 214 is provided on the axis of the pointer 213.

[0049] Example 3, as Figure 5-Figure 9 As shown, the difference from the above embodiment is that the detection mechanism 3 also includes a rotating arm 31, which rotates in the body 1 to cooperate with multiple rotating arms 31. The rotating arm 31 is located just below the detection position in the body 1. The rotating arms 31 are symmetrically distributed on both sides of the detection position in the body 1. A first detection box 32 is fixedly installed on the rotating arm 31 on one side, and the rotation trajectory of the first detection box 32 covers the detection position in the body 1. A second detection box 33 is fixedly installed on the rotating arm 31 on the other side, and the rotation trajectory of the second detection box 33 covers the detection position in the body 1. Measuring position, the size of the first detection box 32 is adapted to the size of the instrument box 211. When the first detection box 32 is attached to the instrument box 211, the first detection box 32 and the instrument box 211 are sealed. The size of the second detection box 33 is adapted to the size of the instrument box 211. When the second detection box 33 is attached to the instrument box 211, the second detection box 33 and the instrument box 211 are sealed. A plurality of first servo motors 34 are arranged in the body 1, and the first servo motors 34 are respectively connected to the power of each rotating arm 31.

[0050] Before testing the instrument box 211, the first servo motor 34 is started, and the first servo motor 34 drives the rotating arm 31 to rotate, and the rotating arm 31 drives the first detection box 32 and the second detection box 33 to rotate and close to the two sides of the instrument box 211. At this time, the first detection box 32 is sealed with the instrument box 211, and the second detection box 33 is sealed with the instrument box 211.

[0051] Furthermore, an air pump 35 is fixedly installed in the body 1, and the air pump 35 is located directly below the first detection box 32. The air inlet end of the air pump 35 is connected to the air supply system. The air pump 35 is used to transport air. An impeller disk 36 is fixedly installed in the body 1, and the impeller disk 36 is located directly below the second detection box 33. An impeller is provided in the impeller disk 36, and the impeller disk 36 is used to detect the flow of air.

[0052] Furthermore, the air supply system is an existing structure, specifically a supporting system for air equipment that supplies air to the air pump 35 in the detection device.

[0053] Furthermore, a hose 37 is provided between the exhaust end of the air pump 35 and the first detection box 32, and a hose 37 is provided between the impeller disc 36 and the second detection box 33. The hose 37 connects the exhaust end of the air pump 35 with the first detection box 32 and the impeller disc 36 with the second detection box 33 respectively. A detector 38 is fixedly mounted on the impeller disc 36. The detection end of the detector 38 is connected to the impeller power of the impeller disc 36. The detector 38 is used to detect the rotation of the impeller in the impeller disc 36.

[0054] Among them, when performing the sealing test, the air pump 35 is started, and the air pump 35 delivers air to the hose 37. The hose 37 sends the air into the first detection box 32, and the flow of air is used to detect the sealing of the instrument box 211. If the sealing of the instrument box 211 is poor, the air will pass through the instrument box 211 and flow into the second detection box 33. The air then flows from the second detection box 33 into the hose 37, and then flows from the hose 37 into the impeller disk 36. The flow of air drives the impeller in the impeller disk 36 to rotate. The detector 38 detects the rotation of the impeller in the impeller disk 36, and determines that the instrument box 211 has a poor sealing problem.

[0055] Furthermore, a horizontal shaft 39 is rotatably mounted in the first detection box 32, and the rotational trajectory of the horizontal shaft 39 covers the docking port 214. The size of the horizontal shaft 39 is adapted to the docking port 214. A second servo motor 310 is fixedly mounted on the first detection box 32, and the second servo motor 310 is power-connected to the horizontal shaft 39. A plurality of sensors 311 are fixedly mounted in the first detection box 32. When the horizontal shaft 39 performs a dynamic balancing test on the instrument gear assembly 212 and the pointer 213, the sensor 311 detects the results of the dynamic balancing test.

[0056] Among them, as the first detection box 32 and the second detection box 33 are closed onto the instrument box 211, the horizontal shaft 39 will be stuck in the docking port 214. When performing dynamic balancing detection, the second servo motor 310 is started again. The second servo motor 310 drives the horizontal shaft 39 to rotate, and the horizontal shaft 39 drives the pointer 213 to rotate. The pointer 213 drives the instrument gear assembly 212 to rotate, and the sensor 311 is used to perform dynamic balancing detection on the parts in the instrument box 211 (i.e., the pointer 213 and the instrument gear assembly 212).

[0057] The overall working principle of the detection device:

[0058] The instrument box 211 is placed on the rail 26, and the transmission system of the production line corresponding to the rail 26 is used to transport the instrument box 211 on the rail 26. After the instrument box 211 is transported to the detection position in the body 1, the instrument box 211 stops moving, and then the detection component 3001 is started. The detection component 3001 is closed on both sides of the instrument box 211. When the detection component 3001 is closed on the instrument box 211, the detection component 3001 and the instrument box 211 are sealed, and then the detection component 3001 uses airflow to blow from one side of the instrument box 211 to the other side. , and detects whether there is gas flow on the other side of the instrument box 211 to detect the sealing of the instrument box 211. At the same time, the detection component 3001 performs dynamic balancing detection on the parts in the instrument box 211. Therefore, compared with the current worker-assisted single-take-one detection detection process, the detection device can be better adapted to the instrument production line. When defective products are found in the detection results, the transmission system to the instrument can be directly stopped, and the operation of the production line can be stopped in time. The detection results are synchronized with the production line, thereby improving the detection efficiency of the detection device and ensuring the quality of the products on the production line.

[0059] When the interior of the detection device needs to be inspected, the hydraulic rod 24 is activated, the extension rod of the hydraulic rod 24 is retracted, and the extension rod of the hydraulic rod 24 drives the connecting frame 25 to move, and the connecting frame 25 drives the sliding member 22 to move on the slide rail 21, and the sliding member 22 drives the sliding door 23 to move, so that the sliding door 23 moves upward to open the open end on the wall of the body 1, so that workers can observe or repair the interior of the body 1 through the open end on the wall;

[0060] When transporting the instrument box 211, the instrument box 211 is placed between the clamping members 29, and the cylinder 210 is started. The cylinder 210 drives the clamping members 29 to clamp the instrument box 211. Then, the stepping motor in the transmission system drives the gear set to operate, the gear set drives the planetary reducer to operate, the planetary reducer drives the screw 28 to rotate, the screw 28 drives the moving platform 27 to move on the rail 26, the moving platform 27 drives the clamping members 29 to move, and the clamping members 29 drive the instrument box 211 to move on the rail 26, so that the instrument box 211 moves to the detection position in the body 1;

[0061] Before testing the instrument box 211, the first servo motor 34 is started. The first servo motor 34 drives the rotating arm 31 to rotate. The rotating arm 31 drives the first detection box 32 and the second detection box 33 to rotate and close to the two sides of the instrument box 211. At this time, the first detection box 32 and the instrument box 211 are sealed, and the second detection box 33 and the instrument box 211 are sealed.

[0062] When performing a seal test, the air pump 35 is started and conveys air to the hose 37. The hose 37 conveys the air into the first test box 32. The flow of air is used to test the seal of the instrument box 211. If the seal of the instrument box 211 is poor, the air will pass through the instrument box 211 and flow into the second test box 33. The air will then flow from the second test box 33 into the hose 37 and then from the hose 37 into the impeller disc 36. The flow of air drives the impeller in the impeller disc 36 to rotate. The detector 38 detects the rotation of the impeller in the impeller disc 36, and thus determines that the instrument box 211 has a poor seal.

[0063] As the first detection box 32 and the second detection box 33 are closed onto the instrument box 211, the horizontal shaft 39 will be stuck in the docking port 214. When performing dynamic balancing detection, the second servo motor 310 is started again. The second servo motor 310 drives the horizontal shaft 39 to rotate, and the horizontal shaft 39 drives the pointer 213 to rotate. The pointer 213 drives the instrument gear assembly 212 to rotate. The sensor 311 is used to perform dynamic balancing detection on the parts in the instrument box 211 (i.e., the pointer 213 and the instrument gear assembly 212).

[0064] A method for detecting the sealing performance of an instrument, using the above-mentioned sealing detection device, comprises the following steps:

[0065] S1: On the production line, the instrument box 211 is transported on the rail 26 to the detection position in the body 1 by using the transmission system;

[0066] S2: Stop conveying after the instrument box 211 moves to the detection position;

[0067] S3: The detection component 3001 is closed onto both sides of the instrument box 211, and the detection component 3001 and the instrument box 211 are closed and sealed. The detection component 3001 uses airflow to perform a sealing test on the instrument box 211, and at the same time performs a dynamic balance test on the parts in the instrument box 211.

[0068] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
