DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] Reference Figure 1-7As shown, a high-density and high-speed surface-mount connector detection device includes a detection table 1 and a slide 12, wherein two parallel slide rails 11 are installed on the detection table 1, and two pairs of slide rail blocks 13 are connected to the bottom surface of the slide 12, and the two pairs of slide rail blocks 13 are respectively slidably connected to the two slide rails 11, and a cylinder 14 is installed on the detection table 1, and the movable end of the cylinder 14 is connected to the slide 12, and the end of the slide 12 away from the cylinder 14 is rotatably connected to a base 15 through a pin shaft, and a first mounting plate 16 is connected to the base 15, and an auxiliary mechanism 3 is provided on the slide 12 for realizing swing-type plug-in and pull-out detection of connectors, and a second mounting plate 17 is connected to the side of the detection table 1 away from the cylinder 14, and an airtight detection mechanism 2 is provided on the second mounting plate 17 for testing the airtight performance of the connector after plugging.

[0027] In this embodiment, a groove 21 is formed on one side of the first mounting plate 16 and the second mounting plate 17 close to each other, a pair of mounting holes 22 are formed on the first mounting plate 16 and the second mounting plate 17 on both sides of the groove 21, and a circle of "U"-shaped sealing strips 23 are embedded on the first mounting plate 16 and the second mounting plate 17 and around the groove 21.

[0028] In this embodiment, the airtight detection mechanism 2 includes a fixed box 24 and an airbag 28. The fixed box 24 is installed on the second mounting plate 17 and is located directly below the sealing strip 23. A pressure block 25 is sealingly and slidably connected inside the fixed box 24. A spring 26 is connected to the pressure block 25. One end of the spring 26 away from the pressure block 25 is connected to the inner box wall of the fixed box 24. An air guide tube 27 is provided on the second mounting plate 17. The two ends of the air guide tube 27 are respectively connected to the fixed box 24 and the groove 21. The airbag 28 is installed on the top of the second mounting plate 17. The airbag 28 is sealed and connected to a connecting pipe 29. The other end of the connecting pipe 29 is connected to the air guide tube 27. During production, the socket 4 and the plug 5 will have a wire hole 6 at the tail end for passing the wire connection pin, as shown in the attached Figure 8 As shown, the present application utilizes the socket 4 to communicate with the groove 21 through the wire hole 6. After the socket 4 and the plug 5 are plugged in, air is inflated into the socket 4 through the wire hole 6 to detect whether there is air leakage at the plug-in location.

[0029] In this embodiment, the auxiliary mechanism 3 includes a guide rail 31 and a sliding rod 35. The guide rail 31 is installed on the detection platform 1 and is parallel to the sliding rail 11. The guide rail 31 is slidably connected to a movable seat 32. The movable seat 32 is connected to two vertical plates 33. The upper ends of the two vertical plates 33 are commonly connected to a limiting rod 34 with a rectangular cross-section. The limiting rod 34 is slidably connected to a limiting block 341. The upper end of the limiting block 341 is connected to a pull rod 342. The sliding rod 35 is connected to the base 15. The sliding rod 35 is slidably connected to a slider 351. The end of the pull rod 342 away from the limiting block 341 is rotatably connected to the slider 351 through a pin.

[0030] In this embodiment, the lower ends of the two vertical plates 33 are connected to a rotating shaft 36 for rotation together, and a rotating cylinder 361 is coaxially connected to the rotating shaft 36. A guide groove 38 is provided on the curved surface of the rotating cylinder 361. The lower end of the limit block 341 is connected to a guide rod 362, and the lower end of the guide rod 362 is slidably connected to the guide groove 38. One end of the rotating shaft 36 passes through the vertical plate 33 and is coaxially connected to a gear 364 through a one-way bearing. A spur rack 363 is installed on the detection platform 1, and the spur rack is arranged parallel to the guide rail 31, and the spur rack 363 is meshed with the gear 364.

[0031] In this embodiment, a threaded rod 37 is provided on the slide 12, and the threaded rod 37 is arranged parallel to the guide rail 31. A connecting block 371 is connected to the vertical plate 33, and the connecting block 371 is connected to the threaded rod 37 through threads. One end of the threaded rod 37 is coaxially connected to a rocker 372.

[0032] In this embodiment, the guide groove 38 is composed of a spiral section 381 and a straight section 382. The two ends of the spiral section 381 are respectively connected to the two ends of the straight section 382. When the guide rod 362 stays in the straight section 382, ​​the limit block 341 is exactly located in the middle position of the limit rod 34. At this time, the slide bar 35 is parallel to the slide rail 11. When the rotating drum 361 rotates one circle, it just drives the limit block 341 to slide back and forth on the limit rod 34 for one cycle. The push and pull stroke distance of the cylinder 14 is set to be the same each time. Through the engagement of the spur rack 363 and the gear 364, the cylinder 14 will drive the gear 364 to rotate three circles each time.

[0033] In this embodiment, an indicator light 18 is installed on the test bench 1 to determine whether the connector is powered on after being plugged in. During the test, after the airtight test is completed, the socket 4 and plug 5 of the connector and the indicator light 18 can be connected to the circuit through wires to detect the conductive performance. Each pair of pins on each connector can be designed as a series circuit. When there is a problem with the contact of a pair of pins, the entire circuit will be powered off and the indicator light 18 will be off.

[0034] In addition, the test bench 1 is also provided with a sensor for counting the number of times the plug 5 and the socket 4 are plugged in and out. The counting sensor can be arranged on the cylinder to count the number of times the cylinder 14 is extended and retracted.

[0035] The working process and principle of the present invention are as follows:

[0036] When in use, firstly, the socket 4 is mounted on the second mounting plate 17 by bolts, and the plug 5 is mounted on the first mounting plate 16 by bolts, and the rocker 372 is rotated to drive the threaded rod 37 to rotate, and the movable seat 32 is controlled to slide, so that the guide rod 362 stays in the straight section 382 of the guide groove 38, and then the cylinder 14 is turned on to push the slide 12 to move. Due to the one-way bearing, when the slide 12 moves forward, it will only drive the gear 364 to rotate, and will not drive the rotating shaft 36 to rotate. The plug 5 will be inserted into the socket 4 with the forward movement of the slide 12. After the plug 5 enters the socket 4, the front end of the slide 12 will abut against the pressure block 25 and continue to push the pressure block 25 to slide. The air in the fixed box 24 is pressurized and will enter the groove 21 and the air bag 28 through the air guide tube 27. After the plug 5 is fully inserted into the socket 4, the state change of the air bag 28 can be observed. If there is an air leakage at the connection between the plug 5 and the socket 4, the air bag 28 will first expand and then shrink or remain in a shrinking state. If there is no air leakage, all the air will enter the air bag 28, and the air bag 28 will expand and remain in an expanded state.

[0037] Afterwards, the control cylinder 14 is pulled back. During the sliding back of the slide 12, the meshing transmission between the gear 364 and the spur rack 363 will drive the rotating shaft 36 to rotate, and through the guidance of the guide groove 38 on the rotating cylinder 361, the limit block 341 is driven to slide back and forth on the limit rod 34, so that the slide rod 35 is pulled by the pull rod 342 to swing left and right, simulating the left and right shaking of the plug 5 when it is pulled out of the socket 4, and restoring the actual use of the connector plugging and unplugging. Later, the control cylinder 14 is repeatedly extended and retracted, and the plugging and unplugging of the connector is repeatedly tested until an airtightness problem occurs. The counting result is checked to obtain the life result of the airtightness detection of the connector plugging and unplugging. After that, the wire can be connected and the plugging and unplugging of the connector is repeatedly tested again. When the indicator light 18 is not on, the counting result is checked to obtain the life result of the conductivity detection of the connector plugging and unplugging. Under normal circumstances, the airtightness life data of the connector is much lower than the conductivity life data.

[0038] In order to increase the diversity of detection data, the rocking wheel 372 can be rotated to drive the threaded rod 37 to rotate, and the thread is used to control the movement of the movable seat 32 to drive the slider 351 to slide on the slider 35, thereby changing the distance between the slider 351 and the first mounting plate 16, thereby realizing the change of the shaking amplitude when the plug 5 is pulled out, so as to obtain the life results of the connector plug-in air tightness test and the conductivity test under different shaking amplitudes. Each time the position of the movable seat 32 is adjusted, the guide rod 362 must stay in the straight section 382 of the guide groove 38.

[0039] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
