[0032] like Figure 1 , 2 As shown in Figure 5, in one embodiment of the present invention, the airtight and pressure-resistant integrated detection device comprises a frame 100, a lifting drive mechanism 200, an upper die base 310 and a lower die base 320; the lower die base 320 is connected to the frame 100; the lifting drive mechanism 200 is connected to the frame 100 and is connected to the upper die base 310; and the upper die base 310 is arranged above the lower die base 320; a material placement gap 323 is provided between the lower die base 320 and the upper die base 310; the material placement gap 323 Used to place the product 400 to be tested; a conductive positioning component 340 is provided in the upper mold base 310; one end of the conductive positioning component 340 extends to the material placement gap 323 and abuts against the product 400 to be tested; a gas storage cavity 321 is provided on the side of the lower mold base 320 facing the upper mold base 310; at least two airtightness detection components are also provided in the lower mold base 320; the airtightness detection component is connected to the gas storage cavity 321; and / or the airtightness detection component is connected to the material placement gap 323.

[0033] The technical solution of the present invention realizes a stable limiting clamping effect on the product to be tested by adopting the material placement gap formed by the upper mold base and the lower mold base, and at the same time combines the conductive positioning component of the upper mold base to perform insulation withstand voltage testing on the product to be tested, and the air tightness detection component and the air guide channel of the lower mold base to perform insulation withstand voltage testing and air tightness testing on the product to be tested, thereby realizing the integration of the insulation durability test operation and the air tightness test operation, thereby improving the compactness of the overall structure, increasing the diversity of the test and improving the test efficiency; avoiding a series of problems such as detection failure and missed detection.

[0034] Specifically, in some embodiments, Figure 1As shown, the frame 100 is provided with an operating cavity; the upper die base 310 and the lower die base 320 are arranged inside the operating cavity; and a photoelectric sensing component 103 is provided at the opening of the operating cavity. The photoelectric sensing component 103 may be a grating or the like. That is, the lifting cylinder 210 and other equipment can be started only after the photoelectric sensing component 103 detects that the loading is completed, thereby improving the stability and safety of the operation.

[0035] Specifically, in some embodiments, Figure 1 and 2 As shown, a wire groove 311 is provided in the upper mold base 310; one end of the wire groove 311 is connected to the material placement gap 323; the other end of the wire groove 311 is connected to the outside of the upper mold base 310; and the conductive positioning component 340 is arranged inside the wire groove 311; one end of the conductive positioning component 340 passes through the other end of the wire groove 311, and is electrically connected to the withstand voltage insulation tester. In other words, this structure can ensure the orderliness and stability of the pressing operation and the insulation withstand voltage detection through the installation and guiding effect of the wire groove 311, thereby improving the test efficiency. Among them, the number of the conductive positioning components 340 is two, and they are conductive positioning components for the positive and negative poles respectively; the number of the wire grooves 311 is two. Among them, in some embodiments, such as Figure 2 As shown, the wire slot 311 includes a horizontal slot and a vertical slot connected to each other obliquely (vertically); the vertical slot is set through the thickness direction of the upper mold base 310; the horizontal slot extends through the horizontal direction of the upper mold base 310; and one end of the conductive positioning component 340 passes through the vertical slot and extends to the material placement gap 323; the other end of the conductive positioning component 340 is connected with a conductive lead wire; the conductive lead wire passes through the horizontal slot and is electrically connected to the withstand voltage insulation tester. This structure can improve the compactness of the overall structure and ensure the orderly conduct of the test. Among them, the withstand voltage insulation tester is also called an electrical insulation strength tester or a dielectric strength tester, and is also called a dielectric breakdown device, an insulation strength tester, a high-voltage tester, a high-voltage breakdown device, a withstand voltage tester, etc. It is an instrument for measuring the withstand voltage strength, which can intuitively, accurately and quickly test the breakdown voltage, leakage current and other electrical safety performance indicators of various objects under test, and can be used as a high-voltage source to test the performance of components and the whole machine. The working principle of the withstand voltage insulation tester is to apply a voltage higher than the normal working voltage to the insulator of the device under test for a specified period of time. If the insulation between them is good enough, the voltage applied will only produce a small leakage current. If the leakage current of the insulator of a device under test remains within the specified range within the specified time, it can be determined that the device under test can operate safely under normal operating conditions. Furthermore, if Figure 1 and 2As shown, the frame 100 is also provided with a pressure display 101; the pressure display 101 is electrically connected to the withstand voltage insulation tester.

[0036] Specifically, in some embodiments, Figure 2 and 4 As shown, the conductive positioning component 340 includes a mounting column 341, a conductive block 342 and an insulating block 343; a mounting channel 344 is provided in the mounting column 341; the top of the mounting channel 344 is connected to the wire slot 311 (middle horizontal slot); the mounting column 341 is connected to the inner wall of the wire slot 311 (middle vertical slot); one end of the insulating block 343 is connected to the bottom of the mounting channel 344; the other end of the insulating block 343 is extended toward the material placement gap 323; the conductive block 342 is connected between the mounting column 341 and the insulating block 343; and one end of the conductive block 342 is connected to a conductive lead wire; one end of the conductive lead wire passes through the mounting channel 344 and the wire slot 311 (middle horizontal slot), and is electrically connected to the withstand voltage insulation tester. The material of the mounting column 341 is the same as that of the insulating block 343. That is to say, the conductive block 342 and the externally insulated mounting posts 341 and insulating blocks 343 on both sides can avoid contact with the upper mold base 310 when testing electrical properties, ensure the safety and stability of use, and improve the accuracy of the test results. Figure 4 As shown, the insulating block 343 and the mounting column 341 are made of insulating resin; the insulating block 343 is an inverted structure and is threadedly connected to the inner wall of the mounting channel 344. The conductive block 342 is made of brass and is embedded in the insulating resin to avoid contact with the upper mold base 310 when testing electrical properties, and to ensure safety and stability in use, thereby improving the accuracy of the test results. Figure 4 As shown, the area of ​​the projection of one side end of the insulating block 343 toward the mounting post 341 toward the mounting post 341 is smaller than the cross-sectional area of ​​the mounting post 341, and the projection of one side end of the insulating block 343 toward the mounting post 341 is arranged on one end surface of the mounting post 341. In other words, a C-shaped, I-shaped or other structure is formed between the insulating block 343 and the mounting post 341; thereby, contact and conduction with the upper die seat 310 can be avoided when testing electrical properties, and the safety and stability of use can be ensured, thereby improving the accuracy of the test results.

[0037] Specifically, in some embodiments, Figure 2 and 3As shown, a test slot 314 is provided on one side of the upper mold base 310 facing the lower mold base 320; (the bottom of the wire slot 311 is connected to the test slot 314;) the conductive positioning component 340 (middle insulating block 343) extends to the test slot 314; and the test slot 314 is arranged above the gas storage cavity 321. Among them, the projection of the test slot 314 toward the lower mold base 320 covers the gas storage cavity 321. In other words, the structure can achieve the extrusion and sealing effect of the upper and lower ends of the product to be tested through the covering test slot, thereby ensuring the orderly progress of the airtightness test and the stability of the signal information transmission of the insulation withstand voltage test.

[0038] Specifically, in some embodiments, Figure 2 and 3 As shown, the test slot 314 is provided with a mounting slot 315 inside; a blocking block 330 is provided inside the mounting slot 315; and the blocking block 330 is sealed against the product to be tested 400. This structure uses the blocking block 330 made of soft silicone to block one or more leaks in the product during the test process, thereby ensuring the orderly conduct of the airtightness test.

[0039] Specifically, in some embodiments, Figure 2 and 5 As shown, at least two limiting posts 324 are provided on one side of the lower die base 320 facing the upper die base 310; the limiting posts 324 are arranged around the lower die base 320, and the material storage gap 323 is formed between the limiting posts 324, the lower die base 320 and the upper die base 310. This structure can avoid the phenomenon of air leakage caused by the shaking of the product 400 to be tested through the surrounding abutment and clamping assembly, thereby improving the accuracy and efficiency of air tightness detection.

[0040] Specifically, in some embodiments, Figure 6 As shown, the gas storage chamber 321 is provided with an abutting seat 3211; the top of the abutting seat 3211 abuts against the product to be tested 400; and the abutting seat 3211 is arranged opposite to the blocking block 330. This structure prevents the product 400 from bending and deforming at this location through the support between the abutting seat 3211 and the blocking block 330, and can also ensure the orderly operation of insulation durability.

[0041] Specifically, in some embodiments, Figure 3 and 5As shown, at least two positioning posts 325 are provided on one side of the lower die base 320 facing the upper die base 310; at least two first positioning holes 312 are provided on one side of the upper die base 310 facing the lower die base 320; the positioning posts 325 can be arranged inside the first positioning holes 312 (further, the outer wall of the positioning posts 325 is clamped on the inner wall of the positioning holes 312). This structure can improve the accuracy and stability of the up and down driving, and avoid affecting the accuracy of the airtightness detection due to air leakage.

[0042] Specifically, in some embodiments, Figure 2 and 6 As shown, the airtightness detection component includes an air guide channel 322 and at least one airtightness detection channel 327; one end of the air guide channel 322 extends into the interior of the lower mold base 320 and is connected to the interior of the gas storage cavity 323; the other end of the air guide channel 322 passes through the side wall of the lower mold base 320 and is used to connect with the blowing equipment (blowing pump and hair dryer); one end of one of the airtightness detection channels 327 passes through the surface of the lower mold base 320 and is connected to the material placement gap 323; the other end of one of the airtightness detection channels 327 passes through the side wall of the lower mold base 320 and is connected to the airtightness testing equipment; one end of the other airtightness detection channel 327 is connected to the gas storage cavity 323; the other end of the other airtightness detection channel 327 passes through the side wall of the lower mold base 320 and is connected to the airtightness testing equipment. This structure detects the air pressure inside the gas storage cavity 323 and the air pressure value of the material placement gap 323 through at least two groups of different airtightness detection channels 327, so as to determine the airtightness of the product 400 to be tested, thereby improving the comprehensiveness and accuracy of the detection.

[0043] Specifically, in some embodiments, Figure 1 and 7 As shown, the lifting drive mechanism 200 includes a lifting cylinder 210 and a mounting seat 220; the lifting cylinder 210 is arranged on the frame 100 and is fixedly connected to the mounting seat 220; the mounting seat 220 is connected to the top of the upper mold base 310; and a magnetic induction valve 212 is arranged on the lifting cylinder 210. Figure 7 As shown, at least one assembly hole 211 is provided on the frame 100 ; at least one guide rod 230 is provided on the mounting seat 220 ; one end of the guide rod 230 is limitedly connected to the inside of the assembly hole 211 .

[0044] The working principle is as follows: put the product 400 to be tested into the designated position of the lower die seat 320. After it is in place, press and start the lifting drive mechanism 200. The air pressure enters the lifting cylinder 210. The cylinder bearing of the lifting cylinder 210 moves downward and starts to apply pressure to the upper die seat 310. After the upper die seat 310 is pressurized, it generates downward pressure on the product 400 to be tested. When the downward pressure stroke of the upper die seat 310 is in place, the airtightness test instrument starts to run and performs an airtightness test on the product 400 to be tested. At the same time, after the bearing of the lifting cylinder 210 moves downward into place, the magnetic sensing valve 212 senses the bearing signal of the lifting cylinder 210, and transmits the signal to the insulation withstand voltage tester through the signal transmission line in the wire slot 311. The switch of the insulation withstand voltage tester is turned on, and the withstand voltage test is performed on the product 400 to be tested. The airtightness test time is 25S, and the withstand voltage test time is 10S. The pressure test is completed during the airtight test. After the pressure test is completed, the test switch is disconnected and the equipment displays the pressure test result. After the airtight test is completed, the cylinder bearing is reset, the upper die seat 310 is raised, and the airtight test equipment displays the airtight test result, and the entire test process is completed. During the test, if the pressure test or airtight test fails, the test equipment will alarm and the test process will be suspended.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.

Therefore, the present invention is not limited to the above specific embodiment, and any obvious improvement, replacement or modification made by those skilled in the art on the basis of the present invention belongs to the protection scope of the present invention.
