Description

Technical Field

[0001] The present invention relates to the technical field of instrument testing, and particularly relates to an intelligent control system for instrument testing. Background Art

[0002] An airtightness detector, also known as a sealing tester or a leakage tester, is mainly applicable to the sealing tests of packaging bags, bottles, tubes, cans, boxes, etc. in industries such as food, pharmaceuticals, medical devices, daily chemicals, automobiles, electronic components, stationery, and consumer electronics.

[0003] When electric vehicles and motorcycles are used outdoors, they often encounter rain. Once the instrument is soaked in water, the internal electronic components will short-circuit, affecting normal use. Therefore, airtightness detection is required during the production and manufacturing of the instrument.

[0004] In the traditional airtightness detection of the instrument, there are gaps in the wiring holes at the bottom of the instrument. A plug is stuffed into the wiring hole of the instrument for sealing, and then the instrument with the plug installed is placed in the container of the airtightness detector. After covering the cover plate of the container, the container is sealed. An air pump is used to pressurize the inside of the container. After pressurizing to the target pressure, the pressurization is stopped. The change in the pressure value is monitored through the pressure sensor connected to the airtightness detector. When the change range of the pressure value is within the normal range, it indicates that the sealing performance of the joint position of the instrument is qualified.

[0005] In the above detection process, it is necessary to manually disassemble and assemble the plug. Since the wiring hole needs to ensure sealing, the plug is often installed tightly and is not easy to pull out, reducing the test efficiency. Summary of the Invention

[0006] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide an intelligent control system for instrument testing, which realizes the automatic sealing of the wiring hole and the sealing box, as well as the automatic placement and taking of the instrument through the mutual cooperation of the main conveyor belt, the pushing mechanism, the sealing member, and the positioning member, improving the test efficiency.

[0007] The technical solution adopted by the present invention is as follows: An intelligent control system for instrument testing includes a testing component, a pushing mechanism, and a main conveyor belt. The pushing mechanism and the testing component are respectively arranged on both sides of the main conveyor belt; A plurality of groups of positioning members are arranged at intervals on the main conveyor belt. The positioning members are used for placing the instrument and limiting both sides of the instrument. A sealing member is installed on the moving end of the pushing mechanism; The testing component is used for testing the airtightness of the instrument. The testing component includes a sealing box, and a sealing port is provided on one side of the sealing box close to the sealing member. The instrument is limited by the positioning member. The pushing mechanism pushes the sealing member into the wiring hole of the instrument. The main conveyor belt continues to convey, causing the instrument to disengage from the positioning member. The pushing mechanism continues to push, pushing the sealing member and the instrument into the test assembly to seal the test assembly. After the test assembly completes the test, the pushing mechanism moves the instrument in the test assembly onto the positioning member and withdraws the sealing member.

[0008] Operating principle: Place the instrument on the positioning member of the main conveyor belt. The main conveyor belt conveys the instrument to the side of the pushing mechanism. The pushing mechanism inserts the sealing member into the instrument. Since the sealing member is tightly connected to the instrument, the instrument no longer moves with the positioning member. The main conveyor belt continues to convey, causing the instrument to disengage from the positioning member. The pushing mechanism pushes the instrument and the sealing member into the sealing box for a sealing test. After completing the sealing test, the pushing mechanism retracts and resets. Through the sealing member, the instrument is moved onto the main conveyor belt. The main conveyor belt continues to convey, causing the instrument to abut against the next positioning member. The pushing mechanism continues to retract and pulls out the sealing member. The instrument is conveyed to the next station following the positioning member.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The instrument is limited by the positioning member, and it is not likely to shift during the conveyance of the main conveyor belt. 2. Through the cooperation of the pushing mechanism and the positioning member, when inserting or pulling out the sealing member, both sides of the instrument are blocked by the positioning member, forcing the sealing member to be inserted into or disengaged from the wiring port, replacing manual plugging and unplugging of the plug. 3. After the sealing member is inserted into the wiring port of the instrument, when the pushing mechanism pushes or retracts, it will drive the instrument and the sealing member to move together, realizing automatic placement and retrieval of the instrument. 4. Through the cooperation of the positioning member, the main conveyor belt and the pushing mechanism, after inserting the sealing member, the main conveyor belt continues to convey, causing the instrument to separate from the positioning member. After completing the test, the pushing mechanism moves the instrument to the front of the next positioning member. The main conveyor belt continues to convey, and the pushing mechanism continues to retract, pulling out the sealing member, enabling the instrument to automatically return to the positioning member.

[0010] As a preferred embodiment of the present invention, the positioning member includes a plurality of first positioning plates. The plurality of first positioning plates are installed on the main conveyor belt along the conveying direction. The first positioning plate includes a bottom plate and side plates. The bottom plate is fixedly installed on the main conveyor belt, and the side plates are fixedly installed at both ends of the bottom plate. A blocking plate is fixedly installed on the sealing box. The blocking plate is located above the first positioning plate. The instrument on the first positioning plate stops conveying after being blocked by the blocking plate. The width of the blocking plate is smaller than the distance between the two side plates.

[0011] Beneficial effects: 1. By setting up a baffle to block the instrument on the positioning part, the instrument is made relatively stationary with respect to the pushing mechanism, and the seal can be inserted without stopping the main conveyor belt, thus improving the test efficiency. 2. During the process of the pushing mechanism pushing the instrument into the sealing box, the baffle can guide the seal and the instrument.

[0012] As a preferred embodiment of the present invention, the pushing mechanism includes a hydraulic cylinder, and the seal includes a plug and a sealing plate. The sealing plate is fixedly installed on the piston rod of the hydraulic cylinder, the plug is fixedly installed inside the sealing plate. After the hydraulic cylinder pushes the instrument into the sealing box, the sealing plate seals the sealing port. The bottom surface of the sealing plate is higher than the top surface of the side plate. After the plug is inserted into the wiring port, the distance between the instrument and the sealing plate is greater than the thickness of the side plate.

[0013] Beneficial effects: By setting up the plug and the sealing plate, when the hydraulic cylinder extends, the plug can be pushed into the wiring port of the instrument. When the hydraulic cylinder continues to extend, the sealing plate, the plug and the instrument can be pushed into the sealing box, and the sealing plate seals the sealing port, meeting the conditions for the sealing test, replacing manual handling of the instrument, and improving the test efficiency.

[0014] As a preferred embodiment of the present invention, the positioning part further includes a plurality of second positioning plates, which have the same structure as the first positioning plates. The second positioning plates are installed on the main conveyor belt along the transmission direction, and the second positioning plates and the first positioning plates are arranged in a staggered manner perpendicular to the conveying direction.

[0015] Beneficial effects: After the test is completed, the hydraulic cylinder contracts, driving the sealing plate, the plug and the instrument to move to the front end of the second positioning plate. The main conveyor belt continues to convey, so that the instrument enters the second positioning plate. The hydraulic cylinder continues to contract. Since the instrument is blocked by the side plate on the second positioning plate, the plug is separated from the instrument, and the instrument follows the second positioning plate to continue to be conveyed to the next station, realizing automated testing and improving the test efficiency.

[0016] As a preferred embodiment of the present invention, a test area is provided between the first positioning plate and the second positioning plate on the main conveyor belt.

[0017] Beneficial effects: According to the transmission speed of the main conveyor belt and the test time, the length of the test area is set. During the test process, the piston rod of the hydraulic cylinder will not interfere with the movement of the positioning part. When the instrument completes the test and is moved to the main conveyor belt by the pushing mechanism, it is located at the front end of the second positioning part, and the step of pulling out the plug continues, so that the main conveyor belt does not need to be repeatedly started and stopped during the whole test process, improving the service life.

[0018] As a preferred embodiment of the present invention, it further includes a separation mechanism. The separation mechanism is arranged below the pushing mechanism, and the separation mechanism removes unqualified instruments, so that the unqualified instruments are separated from the main conveyor belt.

[0019] Beneficial effects: By setting the separation mechanism, the pushing mechanism moves the unqualified instruments to the outside of the main conveyor belt and then removes them, preventing unqualified instruments from flowing into the next process.

[0020] As a preferred embodiment of the present invention, the separation mechanism includes a support table, a first vertical plate and a second vertical plate. The support table is arranged below the pushing mechanism. An installation groove is vertically opened on the support table. A first sliding groove is vertically opened on one side of the installation groove away from the main conveyor belt, and a second sliding groove is vertically opened on one side of the installation groove away from the first sliding groove. The first vertical plate and the second vertical plate are respectively slidably installed in the first sliding groove and the second sliding groove. The upper end of the first vertical plate is fixedly connected with an inclined plate, and a cross plate is fixedly connected to one side of the inclined plate away from the second vertical plate. A compression spring is installed between the cross plate and the support table; Racks are fixedly connected to the inner sides of the first vertical plate and the second vertical plate, and a gear is rotatably installed in the installation groove. The gear meshes with the two racks respectively; The height of the bottom surface of the sealing plate is located between the top surface and the bottom surface of the inclined plate. When the hydraulic cylinder contracts, it drives the sealing plate to move towards the inclined plate. The sealing plate abuts against the inclined plate, causing the cross plate to descend. When the hydraulic cylinder extends, the sealing plate disengages from the inclined plate, and the cross plate is reset by the compression spring.

[0021] Operating principle: When the measured instrument is unqualified, the hydraulic cylinder drives the sealing plate, the plug and the instrument to move to the side of the main conveyor belt close to the pushing mechanism. When the sealing plate contacts the inclined plate, it forces the inclined plate, the first vertical plate and the cross plate to move downward along the first sliding groove, and the compression spring is compressed. Since the rack and the gear are meshed, the second vertical plate moves upward along the second sliding groove. At this time, the second vertical plate is located between the sealing plate and the instrument. The hydraulic cylinder continues to contract, and the instrument is blocked by the second vertical plate, causing the plug to disengage from the instrument; The hydraulic cylinder extends for a test, and the first vertical plate and the second vertical plate are reset by the elasticity of the compression spring.

[0022] Beneficial effects: Through the above structure, the removal of unqualified instruments is automatically completed, preventing unqualified instruments from flowing into the next process; Through the telescoping of the hydraulic cylinder, the installation of the plug and the sealing plate, the taking of the instrument and the removal of unqualified instruments can be completed, reducing the equipment cost.

[0023] As a preferred embodiment of the present invention, a secondary conveyor belt is installed between the separation mechanism and the main conveyor belt. The secondary conveyor belt is located below the sealing plate.

[0024] Beneficial effects: By providing a secondary conveyor belt, the rejected meters fall onto the secondary conveyor belt, preventing unqualified meters from accumulating near the separation mechanism. Description of the Drawings

The side of the instrument 5 with the wiring port faces the pushing mechanism 2; As Figure 2 shown, the positioning member 4 includes a plurality of first positioning plates 41. The plurality of first positioning plates 41 are installed on the main conveyor belt 3 along the transmission direction.

The blocking plate 6 is located above the first positioning plate 41. The instrument 5 on the first positioning plate 41 stops being conveyed after being blocked by the blocking plate 6. The width of the blocking plate 6 is smaller than the distance between the two side plates 412.

[0032] Among them, the positioning member 4 further includes a plurality of second positioning plates 42. The second positioning plates 42 have the same structure as the first positioning plates 41. The second positioning plates 42 are installed on the main conveyor belt 3 along the transmission direction. The second positioning plates 42 are arranged in a staggered manner with the first positioning plates 41. After the plug 211 is inserted into the wiring port, the distance between the instrument 5 and the sealing plate 212 is greater than the thickness of the side plate 412.

[0033] Among them, as Figure 2 shown, a test area 43 is provided on the main conveyor belt 3 between the first positioning plate 41 and the second positioning plate 42.

[0034] Among them, as Figure 1 and Figure 2 shown, a sealing member 21 is installed on the moving end of the pushing mechanism 2. The pushing mechanism 2 includes a hydraulic cylinder 22. The sealing member 21 includes a plug 211 and a sealing plate 212; The sealing plate 212 is fixedly installed on the piston rod of the hydraulic cylinder 22. The plug 211 is fixedly installed on the inner side of the sealing plate 212. After the hydraulic cylinder 22 pushes the instrument 5 into the sealing box 11, the sealing plate 212 seals the sealing port. The bottom surface of the sealing plate 212 is higher than the top surface of the side plate 412. After the plug 211 is inserted into the wiring port, the distance between the instrument 5 and the sealing plate 212 is greater than the thickness of the side plate 412.

[0035] In this embodiment, the hydraulic cylinder 22 can be replaced by an electric push rod.

[0036] Among them, as Figure 3 shown, it further includes a separation mechanism 7. The separation mechanism 7 is arranged below the pushing mechanism 2. The separation mechanism 7 removes the unqualified instruments 5, so that the unqualified instruments 5 are separated from the main conveyor belt 3.

[0037] Among them, as Figures 3 to 5 shown, the separation mechanism 7 includes a support table 71, a first vertical plate 72 and a second vertical plate 73. The support table 71 is arranged below the pushing mechanism 2. An installation groove 74 is vertically opened on the support table 71. A first sliding groove is vertically opened on one side of the installation groove 74 away from the main conveyor belt 3. A second sliding groove is vertically opened on the side of the installation groove 74 away from the first sliding groove. The first vertical plate 72 and the second vertical plate 73 are respectively slidably installed in the first sliding groove and the second sliding groove. The upper end of the first vertical plate 72 is fixedly connected with an inclined plate 75. A cross plate 76 is fixedly connected to the side of the inclined plate 75 away from the second vertical plate 73. A compression spring 77 is installed between the cross plate 76 and the support table 71; Rack bars 78 are fixedly connected to the inner sides of the first vertical plate 72 and the second vertical plate 73. A gear 79 is rotatably installed in the installation groove 74. The gear 79 meshes with the two rack bars 78 respectively; The height of the bottom surface of the sealing plate 212 is located between the top surface and the bottom surface of the inclined plate 75. When the hydraulic cylinder 22 contracts, it drives the sealing plate 212 to move towards the inclined plate 75. The sealing plate 212 abuts against the inclined plate 75, causing the cross plate 76 to descend. When the hydraulic cylinder 22 extends, the sealing plate 212 separates from the inclined plate 75, and the cross plate 76 is reset by the compression spring 77.

[0038] Among them, a secondary conveyor belt 8 is installed between the separation mechanism 7 and the main conveyor belt 3. The secondary conveyor belt 8 is located below the sealing plate 212.

[0039] The usage steps and principles of the present invention are as follows: After starting the main conveyor belt 3, the main conveyor belt 3 conveys the first positioning plate 41 and the instrument 5. The side of the instrument 5 with the wiring port faces the plug 211 until the instrument 5 is blocked by the blocking plate 6. At this time, the instrument 5 is relatively stationary with the sealing plate 212. The hydraulic cylinder 22 pushes the sealing plate 212 and the plug 211. Since the side plate 412 limits the instrument 5, the plug 211 is inserted into the instrument 5. During the insertion process, the main conveyor belt 3 continues to convey. Due to the certain distance between the multiple first positioning plates 41, the instrument 5 is always located on the first positioning plate 41; After the insertion is completed, the main conveyor belt 3 continues to convey until the instrument 5 disengages from the first positioning plate 41. The hydraulic cylinder 22 continues to extend, continuously pushing the sealing plate 212, the plug 211 and the instrument 5. The sealing plate 212 and the instrument 5 move along the baffle plate 6, and the instrument 5 is sent into the sealing box 11, and the sealing plate 212 seals the sealing box 11. The air pump is used to pressurize the inside of the sealing box 11. After pressurizing to the target pressure, the pressurization is stopped. The pressure sensor connected to the airtightness detector is used to monitor the change of the pressure value. When the change range of the pressure value is within the normal range, it means that the sealing performance of the joint position of the electric meter instrument 5 is qualified. During the test process, the main conveyor belt 3 continues to convey, and the test area 43 completely passes through the baffle plate 6. When the test is qualified, the hydraulic cylinder 22 contracts, driving the sealing plate 212, the plug 211 and the instrument 5 to move to the front end of the second positioning plate 42. The main conveyor belt 3 continues to convey, so that the instrument 5 enters the second positioning plate 42. The hydraulic cylinder 22 continues to contract. Since the instrument 5 is blocked by the side plate 412 on the second positioning plate 42, the plug 211 disengages from the instrument 5, and the instrument 5 continues to be conveyed to the next station following the second positioning plate 42. When the test is unqualified, the hydraulic cylinder 22 drives the sealing plate 212, the plug 211 and the instrument 5 to move to the side of the main conveyor belt 3 close to the pushing mechanism 2. When the sealing plate 212 contacts the inclined plate 75, the inclined plate 75, the first vertical plate 72 and the cross plate 76 are forced to move downward along the first sliding groove, and the compression spring 77 is compressed. Since the rack 78 and the gear 79 are engaged, the second vertical plate 73 moves upward along the second sliding groove. At this time, the second vertical plate 73 is located between the sealing plate 212 and the instrument 5. The hydraulic cylinder 22 continues to contract, and the instrument 5 is blocked by the second vertical plate 73, so that the plug 211 disengages from the instrument 5, and the instrument 5 falls on the auxiliary conveyor belt 8.

[0040] The above embodiments are only the preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited by this. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the protection scope required by the present invention.
