Description

Technical Field

[0001] The invention belongs to the technical field of sensor processing and detection, and particularly relates to a sensor processing and detection platform and a use method thereof. Background Art

[0002] Sensors are a type of detection device that can convert the measured information it senses into electrical signals or other forms of output information according to certain rules. According to their basic sensing functions, they can be divided into thermal sensors, photosensitive sensors, gas sensors, and force sensors. Among them, pressure sensors are devices that can sense pressure signals and convert them into electrical signals according to certain rules. They are widely used in various industrial automatic control, water conservancy and hydropower, aerospace, mechanical equipment and other fields.

[0003] During the production and processing of pressure sensors, it is necessary to use a sensor processing and testing bench to perform air-tightness testing on the sensors to ensure the production and processing quality of the pressure sensors. At present, common pressure sensor processing and testing benches mainly use manual loading and unloading to assemble and unload the pressure sensors to be tested. At the same time, manual observation and identification are required to classify the qualified and unqualified pressure sensors. The manual loading and unloading method not only has slow detection efficiency, but also has poor reliability in selecting unqualified pressure sensors. This makes the sensor processing and testing bench less efficient and reliable in performing air-tightness testing on pressure sensors.

[0004] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0005] The object of the present invention is to provide a sensor processing and testing platform and a method of using the same, which can improve the efficiency and reliability of airtightness monitoring of a pressure sensor.

[0006] In order to achieve the above purpose, the technical solution provided by a specific embodiment of the present invention is as follows:

[0007] A sensor processing and testing platform comprises: a testing workbench, a circulating clamping mechanism, a sealing testing mechanism, and an automatic unloading mechanism.

[0008] The circulating clamping mechanism is fixedly assembled above the detection workbench, and the circulating clamping mechanism includes a rotating loading plate, and the rotating loading plate is rotatably assembled above the detection workbench. The outer side of the rotating loading plate is opened with multiple groups of evenly distributed assembly avoidance through holes, and the multiple groups of assembly avoidance through holes are all slidably assembled with supporting trays, and the inner wall of the supporting tray is fixedly sleeved with a sealing inner ring.

[0009] The sealing detection mechanism is fixedly installed on one side of the detection workbench, and the sealing detection mechanism includes an upper sealing detection plug, which is slidably installed above the rotating loading disk, and a lower sealing detection plug is slidably installed below the upper sealing detection plug.

[0010] The automatic unloading mechanism is fixedly assembled on the outer side of the rotating loading plate, and is used to assist the rotating loading plate in performing automatic unloading processing.

[0011] In one or more embodiments of the present invention, a control box is fixedly installed below the detection workbench. The detection workbench, the rotating motor and other auxiliary accessories are assembled and protected by the control box. A plurality of groups of evenly distributed support legs are fixedly connected below the control box. The control box is supported and limited by the plurality of support legs.

[0012] In one or more embodiments of the present invention, an assembly shaft is fixedly connected in the rotating loading plate, and the assembly shaft is rotatably assembled above the detection workbench.

The rotating motor plays the role of providing power, and the rotating loading plate is controlled to rotate by controlling the operation of the rotating motor, so as to facilitate the cyclic loading of the pressure sensor.

[0013] In one or more embodiments of the present invention, both side walls of the plurality of groups of assembly avoidance through holes are provided with limit slots. The limit slots serve to accommodate and limit the guide slider and the buffer airbag. A guide slider is slidably mounted in the limit slots, and the guide slider is fixedly connected to the bearing tray. The guide slider serves to support, fix and slide limit the bearing tray.

[0014] In one or more embodiments of the present invention, multiple groups of clamping cylinders are fixedly mounted on the inspection workbench, and the multiple groups of clamping cylinders are arranged corresponding to the assembly avoidance through holes. The multiple groups of clamping cylinders are used to control the telescopic movement of the moving piston rod. The multiple groups of clamping cylinders are all slidably mounted with a moving piston rod. The fixed connecting plate is moved and controlled by controlling the telescopic movement of the moving piston rod.

[0015] In one or more embodiments of the present invention, a fixed connecting plate is fixedly connected between the movable piston rod and the support plate. The fixed connecting plate serves to connect and fix the movable piston rod and the support plate. A buffer airbag is fixedly connected to the side of the guide slider away from the fixed connecting plate. The buffer airbag serves to store air, and at the same time, the buffer airbag serves to limit the sliding movement of the guide slider. A ventilation air pipe is connected between the buffer airbag and the sealing inner ring. The ventilation air pipe serves to connect the buffer airbag and the sealing inner ring, so that the air in the buffer airbag can be transported along the ventilation air pipe to the sealing inner ring, thereby facilitating the control of the expansion state of the sealing inner ring.

[0016] In one or more embodiments of the present invention, the upper sealing detection plug and the lower sealing detection plug are fixedly connected to a lifting and fixing plate on the side opposite to each other. The upper sealing detection plug and the lower sealing detection plug are controlled to move by controlling the movement of the lifting and fixing plate. An assembly bracket is arranged on one side of the lifting and fixing plate, and the assembly bracket is fixedly connected to the control box. The control cylinder is assembled and fixed by the assembly bracket.

[0017] In one or more embodiments of the present invention, a pair of control cylinders are fixedly mounted on one side of the assembly bracket close to the detection workbench. The sliding and retracting state of the lifting piston rod is controlled by controlling the air intake of the pair of control cylinders. A lifting piston rod is slidably mounted in each of the pair of control cylinders, and the lifting piston rod is fixedly connected to a lifting fixed plate. The lifting piston rod supports, fixes and slides the lifting fixed plate. A guide light rod is slidably mounted on both sides of the pair of control cylinders, and the guide light rod is fixedly connected to a lifting fixed plate. The sliding stability of the lifting piston rod is improved by slidingly guiding the guide light rod.

[0018] In one or more embodiments of the present invention, the automatic unloading mechanism includes a qualified material guide plate and an unqualified material guide plate. The qualified pressure sensor is guided out through the qualified material guide plate. The unqualified pressure sensor is guided out through the unqualified material guide plate. Unloading cylinders are arranged below the qualified material guide plate and the unqualified material guide plate. The telescopic state of the unloading piston rod is controlled by controlling the air intake state of the unloading cylinder. A cylinder assembly frame is fixedly assembled between the unloading cylinder and the detection workbench. The cylinder assembly frame assembles and fixes the unloading cylinder. A unloading piston rod is slidably assembled in the unloading cylinder. The unloading piston rod plays a role of telescopic control on the unloading top block. The unloading piston rod is hinged with a unloading top block at one end outside the unloading cylinder, and the unloading top block is arranged in cooperation with the support tray. The pressure sensor supported in the support tray is assisted in unloading by the ejection of the unloading top block.

[0019] A method for using a sensor processing and testing platform comprises the following steps:

[0020] S1. When the pressure sensor needs to be tested for sealing, the pressure sensor to be tested is placed on the rotating loading plate, the pressure sensor to be tested is supported and limited by the rotating loading plate, and the rotating loading plate is driven to rotate at a fixed angle by controlling the rotation of the rotary motor, so that the pressure sensor to be tested moves between the upper sealing detection plug and the lower sealing detection plug;

[0021] S2. Subsequently, the air intake of the clamping cylinder is controlled so that the movable piston rod in the clamping cylinder is extended, and the bearing plate slides in the limit slide groove as the movable piston rod is extended under the action of the fixed connecting plate, and the buffer airbag is compressed by the movement of the guide slider, so that the air in the buffer airbag can be transported to the sealing inner ring along the air guide pipe, and the pressure sensor to be tested supported on the bearing plate is supplemented and sealed by the expansion of the sealing inner ring;

[0022] S3, by controlling the air intake of a pair of control cylinders to extend a pair of lifting piston rods, thereby respectively controlling the upper sealing detection plug and the lower sealing detection plug to move into the bearing tray, and the upper sealing detection plug, the lower sealing detection plug and the bearing tray cooperate with each other to seal and limit the pressure sensor to be tested;

[0023] S4. After the seal is completed, compressed gas is delivered to the upper sealing detection plug, the lower sealing detection plug and the support tray through the air inlet pipe, and the sealing performance of the pressure sensor to be tested is tested by the change of the air pressure of the pressure sensor to be tested;

[0024] S5. After the test is completed, the pass or fail of the test is recorded, and then the lifting piston rod is retracted and reset by controlling the air intake of the control cylinder, so that the upper sealing test plug and the lower sealing test plug are separated. After the upper sealing test plug and the lower sealing test plug are separated, the rotating loading plate is driven to rotate by controlling the operation of the rotating motor, so that the rotating loading plate moves the pressure sensor that has passed the test to the position of the qualified material guide plate, and moves the pressure sensor that has failed the test to the position of the unqualified material guide plate;

[0025] S6. During the rotation of the rotating loading plate, the movable piston rod can be retracted by controlling the air intake of the clamping cylinder, and the bearing plate can be reset by retracting the movable piston rod, so that the air in the sealing inner ring flows back into the buffer airbag along the air guide pipe. At this time, the sealing inner ring releases the state of limiting and sealing the pressure sensor;

[0026] S7. When it is necessary to unload the pressure sensor on the tray, the unloading cylinder is controlled to have air intake so that the unloading piston rod drives the unloading ejecting block to be ejected, and the pressure sensor supported in the tray is guided out by the ejecting ejecting block.

[0027] Compared with the prior art, the present invention can perform cyclic conveying and automatic unloading of the pressure sensor by setting up a cyclic clamping mechanism and an automatic unloading mechanism, which greatly simplifies the process of air tightness testing of the pressure sensor and significantly improves the efficiency and reliability of air tightness testing of the pressure sensor.

[0046] Specifically, a plurality of evenly distributed assembly avoidance through holes are drilled on the outer side of the rotating loading plate 201. The assembly avoidance through holes are drilled to provide assembly operation space for the support plate 202.

[0047] like Figure 1 to Figure 2 As shown, a plurality of assembly avoidance through holes are all slidably mounted with a support tray 202. The support tray 202 plays a role of supporting and limiting the pressure sensor.

[0048] like Figures 7 and 8 As shown, a sealing inner ring 203 is fixedly mounted on the inner wall of the support tray 202. The sealing inner ring 203 improves the stability of the support and limit of the pressure sensor. At the same time, the clamping and sealing state of the pressure sensor in the support tray 202 can be controlled by controlling the expansion and contraction state of the sealing inner ring 203.

[0049] The two side walls of the plurality of assembly avoidance through holes are provided with limit slots, which play a role in accommodating and limiting the guide slider 206 and the buffer airbag 210 .

[0054] like Figures 7 and 8 As shown, a buffer airbag 210 is fixedly connected to one side of the guide slider 206 away from the fixed connecting plate 209. The buffer airbag 210 plays the role of storing air and at the same time, the buffer airbag 210 plays the role of sliding limit for the guide slider 206.

[0055] like Figures 7 and 8 As shown, a venting tube 211 is connected between the cushioning airbag 210 and the sealing inner ring 203. The venting tube 211 serves to connect the cushioning airbag 210 and the sealing inner ring 203, so that the air in the cushioning airbag 210 can be transported to the sealing inner ring 203 along the venting tube 211, thereby controlling the expansion state of the sealing inner ring 203.

The upper sealing detection plug 301 and the lower sealing detection plug 302 are both connected to the side opposite to each other with an air inlet pipe 303. Compressed gas is transported into the pressure sensor through the air inlet pipe 303, so as to detect the air tightness of the pressure sensor.

[0057] like Figure 3 to Figure 4 As shown, the upper sealing detection plug 301 and the lower sealing detection plug 302 are fixedly connected to the side opposite to each other with a lifting fixed plate 304.

[0059] like Figure 3 to Figure 4As shown, a pair of control cylinders 306 are fixedly mounted on one side of the assembly bracket 305 close to the detection workbench 1. The sliding and telescopic state of the lifting piston rod 307 is controlled by controlling the air intake of the pair of control cylinders 306.

[0060] like Figure 6 As shown, a pair of control cylinders 306 are both slidably equipped with lifting piston rods 307, and the lifting piston rods 307 are fixedly connected to the lifting fixed plate 304. The lifting piston rods 307 play the role of supporting, fixing and sliding guiding the lifting fixed plate 304.

[0061] like Figure 3 to Figure 4 As shown, both sides of a pair of control cylinders 306 are slidably equipped with guide light rods 308, and the guide light rods 308 are fixedly connected to the lifting fixed plate 304. The sliding stability of the lifting piston rod 307 is improved by slidingly guiding the guide light rods 308.

[0062] like Figures 3 to 5 As shown, the automatic unloading mechanism 4 is fixedly assembled on the outer side of the rotating loading plate 201, and the automatic unloading mechanism 4 is used to assist the rotating loading plate 201 in performing automatic unloading processing.

[0063] like Figures 3 to 5 As shown, the automatic unloading mechanism 4 includes a qualified material guide plate 401 and an unqualified material guide plate 402. The qualified pressure sensors are guided out through the qualified material guide plate 401, and the unqualified pressure sensors are guided out through the unqualified material guide plate 402.

[0064] like Figures 3 to 5 As shown, a discharge cylinder 403 is arranged below the qualified material guide plate 401 and the unqualified material guide plate 402. The telescopic state of the discharge piston rod 405 is controlled by controlling the air intake state of the discharge cylinder 403.

[0065] like Figures 3 to 5 As shown, a cylinder assembly frame 404 is fixedly mounted between the unloading cylinder 403 and the detection workbench 1. The cylinder assembly frame 404 assembles and fixes the unloading cylinder 403.

[0066] like Figures 3 to 5 As shown, a discharging piston rod 405 is slidably mounted in the discharging cylinder 403. The discharging piston rod 405 plays a role in telescopic control of the discharging top block 406.

[0067] like Figures 3 to 5 As shown, one end of the discharge piston rod 405 outside the discharge cylinder 403 is hinged with a discharge top block 406, and the discharge top block 406 is arranged in cooperation with the support tray 202. The pressure sensor supported in the support tray 202 is assisted in discharge by the ejection of the discharge top block 406.

[0068] A method for using a sensor processing and testing platform. When a pressure sensor needs to be tested for sealing, the pressure sensor to be tested is placed on a rotating loading disk 201, and the rotating loading disk 201 is used to support and limit the pressure sensor to be tested. The rotating loading disk 201 is driven to rotate at a fixed angle by controlling the rotation of a rotating motor 205, so that the pressure sensor to be tested is moved between an upper sealing detection plug 301 and a lower sealing detection plug 302.

[0069] Subsequently, the air intake of the clamping cylinder 207 is controlled so that the movable piston rod 208 in the clamping cylinder 207 is extended, and the support tray 202 slides in the limiting slide groove as the movable piston rod 208 is extended under the action of the fixed connecting plate 209. The buffer airbag 210 is compressed by the movement of the guide slider 206, so that the air in the buffer airbag 210 can be transported to the sealing inner ring 203 along the air guide pipe 211, and the pressure sensor to be tested supported on the support tray 202 is assisted in limiting and sealing.

[0070] By controlling the air intake of a pair of control cylinders 306, a pair of lifting piston rods 307 are extended, thereby respectively controlling the upper sealing detection plug 301 and the lower sealing detection plug 302 to move into the supporting tray 202, and the upper sealing detection plug 301, the lower sealing detection plug 302 and the supporting tray 202 cooperate with each other to seal and limit the pressure sensor to be tested.

[0071] After sealing, compressed gas is delivered to the upper sealing detection plug 301, the lower sealing detection plug 302 and the support tray 202 through the air inlet pipe 303, and the sealing performance of the pressure sensor to be tested is tested by changing the air pressure of the pressure sensor to be tested.

[0072] After the detection is completed, the pass or fail of the detection is recorded, and then the lifting piston rod 307 is retracted and reset by controlling the air intake of the control cylinder 306, so that the upper sealing detection plug 301 is separated from the lower sealing detection plug 302. After the upper sealing detection plug 301 is separated from the lower sealing detection plug 302, the rotating loading disk 201 is driven to rotate by controlling the operation of the rotating motor 205, so that the rotating loading disk 201 moves the pressure sensor that has passed the test to the position of the qualified material guide plate 401, and moves the pressure sensor that has failed the test to the position of the unqualified material guide plate 402.

[0073] During the rotation of the rotating loading plate 201, the movable piston rod 208 can be retracted by controlling the air intake of the clamping cylinder 207, and the supporting plate 202 can be reset by retracting the movable piston rod 208, so that the air in the sealing inner ring 203 can flow back into the buffer airbag 210 along the vent pipe 211. At this time, the state in which the sealing inner ring 203 limits and seals the pressure sensor is released.

[0074] When the pressure sensor on the tray 202 needs to be unloaded, the unloading cylinder 403 is controlled to have air intake so that the unloading piston rod 405 drives the unloading ejecting block 406 to be ejected, and the pressure sensor supported in the tray 202 is exported by the ejecting ejecting block 406.

[0075] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.

After the upper sealing test plug and the lower sealing test plug are separated, the rotating loading plate is driven to rotate by controlling the operation of the rotating motor, so that the rotating loading plate moves the pressure sensor that has passed the test to the position of the qualified material guide plate, and moves the pressure sensor that has failed the test to the position of the unqualified material guide plate; S6. During the rotation of the rotating loading plate, the movable piston rod can be retracted by controlling the air intake of the clamping cylinder, and the bearing plate can be reset by retracting the movable piston rod, so that the air in the sealing inner ring flows back into the buffer airbag along the air guide pipe. At this time, the sealing inner ring releases the state of limiting and sealing the pressure sensor; S7. When it is necessary to unload the pressure sensor on the tray, the unloading cylinder is controlled to have air intake so that the unloading piston rod drives the unloading ejecting block to be ejected, and the pressure sensor supported in the tray is guided out by the ejecting ejecting block.
