DETAILED DESCRIPTION

[0023] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0024] As shown in Figure 1 The first embodiment provided by the present application is an air compressor oil injection detection device, which comprises a rack 1, a conveying line 2 arranged on the rack 1, a plurality of jigs 3 conveyed along the conveying line 2, an oil injection mechanism 4 along the conveying direction of the conveying line 2, and a pressure resistance detection mechanism 5.

[0025] In actual use, the jig 3 is moved to below the oil injection mechanism 4 through the conveying line 2, and the product is injected with compressor oil through the oil injection mechanism 4. When the product is finished with oil injection, the jig 3 is moved to the corresponding position of the pressure resistance detection mechanism 5 through the conveying line 2, and the pressure resistance performance of the product is tested through the pressure resistance detection mechanism 5.

[0026] In the above design, the pressure resistance of the product after being injected with oil is tested, which can test whether the pressure resistance of the product in the real working environment is qualified, so that the test result is more in line with the actual application working condition of the product.

[0027] Specifically, as shown in Figure 1As shown, the oil injection mechanism 4 comprises a first support 41 arranged on the frame 1, a three-axis driving module 42 arranged on the first support 41, an oil injection assembly 43 driven by the three-axis driving module 42, and an oil receiving assembly 44.

[0028] In actual use, when the product moves to the position corresponding to the oil injection mechanism 4, the oil injection assembly 43 moves to the oil injection position through the three-axis driving module 42, and then the oil injection assembly 43 injects oil into the product. When the product is finished injecting oil and the oil injection assembly 43 does not need to inject oil, the oil receiving assembly 44 blocks the lower end of the oil injection assembly 43 to timely receive the oil dripping from the oil injection assembly 43.

[0029] In the above design, the structural design and specific implementation of the oil injection mechanism 4 can effectively realize the oil injection into the product and the receiving of the oil dripping from the oil injection assembly 43, preventing the oil dripping from the oil injection assembly 43 from falling onto the conveying line 2.

[0030] Specifically, as shown in Figure 2 The three-axis driving module 42 comprises a first linear guide rail 421 arranged on the first support 41 along the Y-axis direction, a first sliding seat 422 slidingly arranged on the first linear guide rail 421, a first linear module 423 arranged on the first support 41 for driving the first sliding seat 422 to slide along the first linear guide rail 421, a second linear module 424 arranged on the first sliding seat 422 along the X-axis direction, a connecting plate 425 vertically arranged at the output end of the second linear module 424, and a third linear module 426 vertically arranged on the connecting plate 425. The oil injection assembly 43 is arranged at the output end of the third linear module 426, and the oil receiving assembly 44 is arranged at the lower end of the connecting plate 425.

[0031] In actual use, the first sliding seat 422 moves along the first linear guide rail 421 through the first linear module 423, driving the second linear module 424 and the third linear module 426 to move synchronously, and the connecting plate 425 drives the third linear module 426 to move along the X-axis direction through the second linear module 424, so that the oil injection assembly 43 and the oil receiving assembly 44 move synchronously. The third linear module 426 drives the oil injection assembly 43 to move up and down.

[0032] In the above design, the structural design and specific implementation of the three-axis driving module 42 can effectively realize the movement of the oil injection assembly 43 and the oil receiving assembly 44 to the predetermined position.

[0033] Specifically, as shown in Figure 2 The oil injection assembly 43 comprises a mounting block 431 arranged at the output end of the third linear module 426, an electromagnetic valve 432 arranged on the mounting block 431, and a liquid outlet pipe 433 in communication with the electromagnetic valve 432.

[0034] In actual use, solenoid valve 432 is connected to the external oil supply line. When oil needs to be added to the product, solenoid valve 432 controls the valve core to open, allowing oil from the external oil supply line to flow into the outlet pipe 433 and then into the product. After oiling is completed, the valve core of solenoid valve 432 closes.

[0035] In the above design, the structural design and specific implementation of the oil injection component 43 can effectively realize the oil injection of the product.

[0036] Specifically: such as Figure 2 As shown, the oil receiving assembly 44 includes a first cylinder 441 horizontally disposed at the lower end of the connecting plate 425 and a box 442 disposed at the output end of the first cylinder 441. The lower end of the box 442 is provided with a liquid outlet that communicates with an external tank. The first cylinder 441 drives the box 442 to move below the liquid outlet pipe 433 to receive residual oil.

[0037] In actual use, when the oil filling assembly 43 is filling oil, the box body 442 is located to the side and below the oil filling assembly 43 under the drive of the first cylinder 441. After the oil filling assembly 43 has finished filling oil, the first cylinder 441 drives the box body 442 to extend below the liquid outlet pipe 433 of the oil filling assembly 43, so that the oil remaining in the liquid outlet pipe 433 drips into the box body 442.

[0038] In the above design, the structural design and specific implementation of the oil receiving component 44 facilitate the receiving of residual oil in the oil injection component 43.

[0039] Specifically: such as Figure 3 As shown, the withstand voltage testing mechanism 5 includes a withstand voltage tester mounted on the frame 1, a plug assembly 51 connected to the return terminal of the withstand voltage tester, and a probe assembly 52 connected to the output terminal of the withstand voltage tester. The fixture 3 includes a body 31 and a socket 32 ​​mounted on the body 31. The body 31 is used to hold the product, the socket 32 ​​is used to mate with the plug assembly 51, and the probe assembly 52 is used to contact the product casing. The product is electrically connected to the socket 32 ​​of the fixture 3.

[0040] In actual use, the product stops when it reaches the corresponding position of the withstand voltage testing mechanism 5 along with the fixture 3. Then, the plug assembly 51 extends into the socket 32, and the probe assembly 52 contacts the product shell. Current flows from the output end of the withstand voltage tester along the probe 524 to the product shell. If there is current inside the product, it will flow along the fixture 3 to the plug assembly 51 and enter the return end of the withstand voltage tester. The withstand voltage tester automatically compares the value at the return end with the preset value to determine whether the product's withstand voltage is qualified.

[0041] In the above design, the structural design of the pressure testing mechanism 5 enables pressure testing of the product after oil injection, and the entire testing process is highly automated.

[0042] Specifically: such as Figure 3 As shown, the plug assembly 51 includes a second socket 511 mounted on the frame 1, a second cylinder 512 mounted on the second socket 511, a connecting bracket 513 mounted on the output end of the second cylinder 512, and a plug 514 mounted on the connecting bracket 513.

[0043] In actual use, the connecting bracket 513 is driven by the second cylinder 512 to move the plug 514 so that the plug 514 can connect with or disconnect from the socket 32.

[0044] In the above design, the structural design and specific implementation of the plug assembly 51 can effectively achieve the cooperation with the socket 32 ​​of the fixture 3.

[0045] Specifically: such as Figure 3 As shown, the probe assembly 52 includes a fourth support 521 mounted on the frame 1, a fourth cylinder 522 mounted vertically on the fourth support 521, a fourth plate 523 mounted on the output end of the fourth cylinder 522, and a probe 524 mounted on the fourth plate 523.

[0046] In actual use, when conducting a pressure test, cylinder 522 drives plate 523 to move probe 524 downward, so that the lower end of probe 524 contacts the outer shell of the product.

[0047] In the above design, the structural design and specific implementation of the probe assembly 52 can effectively achieve contact with the product casing.

[0048] Specifically: such as Figure 1 As shown, the conveyor line 2 includes an upper line body 21 mounted on the frame 1, a lower line body 22 located below the upper line body 21, and a first lifting assembly 23 mounted on the frame 1. The first lifting assembly 23 corresponds to the oil injection mechanism 4.

[0049] In actual use, the device of this application is connected to an external production line. The fully loaded fixture 3 is transported through the upper line 21, and the unloaded fixture 3 is transported through the lower line 22. When the oil injection process is performed, the first lifting component 23 needs to lift the fixture 3 from the upper line 21. After the oil injection is completed, the first lifting component 23 descends so that the fixture 3 returns to the upper line 21.

[0050] In the above design, the structural design and specific implementation of conveyor line 2 facilitates docking with external production lines.

[0051] The second embodiment provided in the application is an air compressor oil injection detection method, which adopts the air compressor oil injection detection device and comprises the following steps: S1, the jig 3 is conveyed to the corresponding position of the oil injection mechanism 4 along the conveying line 2, and the oil injection mechanism 4 is used to inject oil into the product; S2, the jig 3 is conveyed to the corresponding position of the pressure resistance detection mechanism 5 along the conveying line 2, and the pressure resistance detection mechanism 5 is used to test the pressure resistance performance of the product after the oil injection.

[0052] In the above design, the pressure resistance test of the air compressor after the oil injection can be effectively realized, so that the pressure resistance test can be more in line with the actual use state of the air compressor.

[0053] It should be understood that the above description is only a specific embodiment of the application and is not used to limit the application.
