[0032] As Figure 1 , 2 and 5, in an embodiment of the present application, the airtight and pressure-resistant integrated detection device; including rack 100, lifting drive mechanism 200, upper die holder 310 and lower die holder 320; the lower die holder 320 is connected to the rack 100; the lifting drive mechanism 200 is connected to the rack 100, and is connected with the upper die holder 310; and the upper die holder 310 is arranged above the lower die holder 320; the lower die holder 320 and the upper die holder 310 are provided with material placing gap 323; the material placing gap 323 is used for placing the product to be tested 400; the upper die holder 310 is provided with conductive positioning part 340; one end of the conductive positioning part 340 extends to the material placing gap 323, and abuts against the product to be tested 400; the side of the lower die holder 320 facing the upper die holder 310 is provided with gas storage cavity 321; the lower die holder 320 is further provided with at least two airtightness detection parts; the airtightness detection parts are in communication with the gas storage cavity 321; and / or the airtightness detection parts are in communication with the material placing gap 323.

[0033] The technical scheme of the present application realizes stable positioning and clamping of the product to be tested by using the material placing gap formed by the upper die holder and the lower die holder, and realizes the integration of insulation and pressure test operation and airtightness test operation by combining the conductive positioning part of the upper die holder for insulation and pressure test of the product to be tested, and the airtightness detection part and the gas guide channel of the lower die holder for airtightness detection of the product to be tested, 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, as Figure 1As shown, the rack 100 is provided with an operation cavity; the upper die holder 310 and the lower die holder 320 are arranged inside the operation cavity; and the opening of the operation cavity is provided with a photoelectric sensing component 103. The photoelectric sensing component 103 can 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 feeding is completed, thereby improving the stability and safety of the operation.

[0035] Specifically, in some embodiments, as shown in Figure 1 and 2 shown, the upper die holder 310 is provided with a wire slot 311; one end of the wire slot 311 is in communication with the material placing gap 323; the other end of the wire slot 311 is in communication with the outside of the upper die holder 310; and the conductive positioning component 340 is arranged inside the wire slot 311; one end of the conductive positioning component 340 passes through the other end of the wire slot 311 and is electrically connected with the insulation withstand voltage tester. That is, the installation and guiding effect of the wire slot 311 can ensure the orderliness and stability of the pressing operation and the insulation withstand voltage detection, thereby improving the test efficiency. The number of the conductive positioning components 340 is two, and each is a positive or negative conductive positioning component; the number of the wire slots 311 is two. In some embodiments, as shown in Figure 2 shown, the wire slot 311 includes a horizontal slot and a vertical slot which are connected at an inclination (perpendicularity); the vertical slot is arranged through the thickness direction of the upper die holder 310; the horizontal slot is arranged through the horizontal direction of the upper die holder 310; one end of the conductive positioning component 340 passes through the vertical slot and extends to the material placing 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 with the insulation withstand voltage tester. This structure can improve the compactness of the overall structure and can ensure the orderly test. The insulation withstand voltage tester is also called electrical insulation strength tester or dielectric strength tester, and is also called dielectric breakdown device, insulation strength tester, high voltage tester, high voltage breakdown device, pressure test instrument, etc. It is an instrument for measuring pressure strength, which can directly, accurately and quickly test the breakdown voltage, leakage current and other electrical safety performance indicators of various measured objects, and can be used as a high voltage source to test the performance of components and complete machines. The working principle of the insulation withstand voltage tester is to apply a voltage higher than the normal working voltage to the insulation body of the measured device for a specified period of time, and if the insulation is good enough, the voltage applied will only produce a small leakage current. If the leakage current of the insulation body of a measured device remains within a specified range within a specified period of time, it can be determined that the measured device can safely operate under normal operating conditions. Further, as shown in Figure 1 and 2As shown, the rack 100 is also provided with a pressure display 101; the pressure display 101 is electrically connected with the pressure insulation tester.

[0036] Specifically, in some embodiments, as shown in 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; the mounting column 341 is internally provided with a mounting channel 344; the top of the mounting channel 344 is in communication with 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 extends towards 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 with the pressure insulation tester. Wherein, the material of the mounting column 341 is the same as that of the insulating block 343. That is, by having the conductive block 342 with electrical conductivity and the mounting column 341 and the insulating block 343 on both sides which are externally insulated, it can avoid conduction between the upper mold base 310 and the contact during testing of electrical properties, and ensure safety and stability in use, and improve the accuracy of detection results. Further, as shown in Figure 4 The materials of the insulating block 343 and the mounting column 341 are both insulating resin; the insulating block 343 is a reverse structure and is threadedly connected to the inner wall of the mounting channel 344. The material of the conductive block 342 is brass and is embedded in the insulating resin, which can avoid conduction between the upper mold base 310 and the contact during testing of electrical properties, and ensure safety and stability in use, and improve the accuracy of detection results. Still further, as shown in Figure 4 The area of the projection of the side end of the insulating block 343 towards the mounting column 341 towards the mounting column 341 is less than the cross-sectional area of the mounting column 341, and the projection of the side end of the insulating block 343 towards the mounting column 341 is arranged on one end surface of the mounting column 341. That is, a C-shaped, I-shaped or other structure is formed between the insulating block 343 and the mounting column 341; thereby it can avoid conduction between the upper mold base 310 and the contact during testing of electrical properties, and ensure safety and stability in use, and improve the accuracy of detection results.

[0037] Specifically, in some embodiments, as shown in Figure 2 and 3As shown, the upper die holder 310 is provided with a test slot 314 on one side of the lower die holder 320; the bottom of the wire slot 311 communicates with the test slot 314; the conductive positioning component 340 (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 towards the lower die holder 320 covers the gas storage cavity 321. That is, this structure can realize the extrusion sealing effect of the product to be tested at both ends through the covering test slot, so as to ensure the orderly progress of the airtightness detection, and also ensure the signal information transmission stability of the insulation voltage test.

[0038] Specifically, in some embodiments, as shown in Figure 2 and 3 As shown, the inside of the test slot 314 is provided with a mounting slot 315; the inside of the mounting slot 315 is provided with a plug 330; and the plug 330 is sealed and abuts against the product to be tested 400. This structure uses the plug 330 made of soft silica gel to block the leak hole of the product in the test process; so as to ensure the orderly progress of the airtightness detection.

[0039] Specifically, in some embodiments, as shown in Figure 2 and 5 As shown, the lower die holder 320 is provided with at least two limiting columns 324 on one side surface of the upper die holder 310; the limiting columns 324 are arranged around the lower die holder 320, and the limiting columns 324, the lower die holder 320 and the upper die holder 310 form the material storage gap 323. This structure can avoid the shaking of the product to be tested 400 to cause air leakage and other phenomena through the assembly form of the surrounding abutting card, so as to improve the accuracy and efficiency of the airtightness detection.

[0040] Specifically, in some embodiments, as shown in Figure 6 As shown, the inside of the gas storage cavity 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 plug 330. This structure can avoid the bending deformation of the product 400 at this place through the support between the abutting seat 3211 and the plug 330, and also can ensure the orderly progress of the insulation operation.

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

[0042] Specifically, in some embodiments, as shown in Figure 2 and 6 As shown, the air tightness detection component includes a gas guide channel 322 and at least one air tightness detection channel 327; one end of the gas guide channel 322 extends into the inside of the lower die seat 320 and communicates with the inside of the gas storage cavity 323; the other end of the gas guide channel 322 penetrates through the side wall of the lower die seat 320 and is used for communicating with a gas blowing device (a gas blowing pump and a gas blower); one end of one of the air tightness detection channels 327 penetrates through the surface of the lower die seat 320 and communicates with the material placing gap 323; the other end of one of the air tightness detection channels 327 penetrates through the side wall of the lower die seat 320 and communicates with an air tightness testing device; one end of another of the air tightness detection channels 327 communicates with the gas storage cavity 323; the other end of another of the air tightness detection channels 327 penetrates through the side wall of the lower die seat 320 and communicates with the air tightness testing device. This structure can detect the air pressure in the inside of the gas storage cavity 323 and the air pressure value of the material placing gap 323 through at least two groups of different air tightness detection channels 327, so as to judge the air tightness of the product 400 to be detected, thereby improving the comprehensiveness and accuracy of the detection.

[0043] Specifically, in some embodiments, as shown in Figure 1 and 7 As shown, the lifting driving mechanism 200 includes a lifting cylinder 210 and a mounting seat 220; the lifting cylinder 210 is arranged on the rack 100 and is fixedly connected with the mounting seat 220; the mounting seat 220 is connected to the top of the upper die seat 310; and the lifting cylinder 210 is provided with a magnetic induction valve 212.

[0044] The working principle is: the product to be tested 400 is placed in the designated position of the lower mold base 320, after being placed in position, the start-up lifting drive mechanism 200 is pressed, the air pressure enters the lifting cylinder 210, the cylinder bearing of the lifting cylinder 210 moves downward, and the pressure on the upper mold base 310 is started. After the upper mold base 310 is pressed, the product to be tested 400 generates a downward pressure. When the downward stroke of the upper mold base 310 is in place, the air-tight test instrument starts to run, and the product to be tested 400 is tested for air tightness. At the same time, after the bearing of the lifting cylinder 210 moves to the position, the magnetic induction valve 212 senses the bearing signal of the lifting cylinder 210, and transmits the signal to the insulation voltage tester through the signal transmission line in the wire slot 311. The switch of the insulation voltage tester is opened, and the product to be tested 400 is tested for voltage resistance. The air tightness test time is 25S, and the voltage resistance test time is 10S. The voltage resistance test is completed during the air tightness test, and after the voltage resistance test is completed, the test switch is turned off, and the equipment displays the voltage resistance test result. After the air tightness test is completed, the cylinder bearing is reset, the upper mold base 310 is lifted, the air tightness test equipment displays the air tightness test result, and the whole test process is completed. During the test process, if the voltage resistance test or the air tightness test is unqualified, the test equipment will alarm, and the test process will be paused.
