Description

Technical Field

[0001] The invention belongs to the technical field of equipment testing, and in particular is a motor drive aging device for new energy vehicles. Background Art

[0002] PCBA, also known as printed circuit board, is the provider of electrical connections for electronic components. According to the number of layers of the circuit board, it can be divided into single-sided board, double-sided board, four-layer board, six-layer board and other multi-layer boards. With the development of technology, the size of electronic components on printed circuit boards is getting smaller and smaller, and the lines on the circuit boards are getting thinner and denser, so the quality requirements for circuit boards are getting higher and higher. Among them, the high-temperature load aging process of PCBA is one of the tasks of testing PCBA.

[0003] The PCBA to be aged is placed in the fixture of the equipment. After the fixture is pushed in, the equipment starts high-temperature aging. During the aging process, the PCBA will be powered on and high temperature will be applied to achieve the operation of the circuit board in a high-temperature environment. Since the board models tested may be different, the equipment needs to debug the corresponding parameters according to different boards.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. The device can systematically perform power-on aging detection on the circuit boards placed in the receiving bottom frame, and the receiving components in the working state are in a relatively closed state. When the circuit boards are heated, the heat is always gathered inside the receiving components, and the inside of the pressure-maintaining outer box basically does not generate heat. Therefore, when the inspectors extract the receiving components, there will be no high temperature environment inside the pressure-maintaining outer box that can easily cause burns to the operators, thereby allowing relevant personnel to operate more safely.

[0013] 2. After the heating work is completed, the heating plate can be stopped first. At this time, the gas introduced into the interior of the container not only does not have high heat, but also takes away the heat inside the container bottom frame and discharges it from the external exhaust pipe on the back, thereby achieving a cooling effect on the interior of the container bottom frame, preventing the operator from encountering a large amount of hot air when opening the closed cover and getting injured. Since each container is relatively independently set, the internal control inner board can be debugged according to the parameters, so the ambient temperature inside each container can be adjusted differently, thereby making the test temperature range of the circuit board larger and the detection effect more accurate.

[0014] 3. The gas entering the bottom frame will generate high temperature through the heating plate. The air inlet end is improved to ensure that the gas can enter the hollow plate attached to the wall only when the pressure inside the pressure-maintaining outer box is large enough. When the pressure is reduced, the air pressure is not enough to push the inner slide. At this time, the guide groove of the inner slide will be closed by the gasket sleeve to prevent the gas inside the hollow plate attached to the wall from flowing back and being discharged into the pressure-maintaining outer box, which plays a protective role and prevents the high-temperature gas from flowing back from the inside of the containing component to the inside of the pressure-maintaining outer box, causing the problem of high-temperature gas leakage.

[0015] 4. As impurities in the air will affect the cleanliness inside the device, a dust screen is installed at the air inlet of the drainage rail to play a certain filtering function. The sliding brush plate has the same air inlet area as the drainage rail, so the sliding brush plate can block the air inlet of the drainage rail to ensure the internal pressure of the pressure-maintaining outer box. After the work is completed, the propulsion cylinder drives the sliding brush plate to slide up and down through the traction rod to wipe the filter plate part of the drainage rail, thereby cleaning up the impurities on the dust screen and unblocking its opening.

[0029] The heating component 5 includes a hollow plate 51 attached to the wall, and a control inner plate 53 is fixedly connected to the bottom of the inner wall of the hollow plate 51. The upper surface of the control inner plate 53 is fixedly connected to a heating electric plate 52 through a guide rod. The air inlet terminal 6 is evenly arranged on the side of the inner cavity of the hollow plate 51 away from the protective rotating drum 45. The protective rotating drum 45 simultaneously supplies power to the internal socket 48 and the closed cover plates 43 on both sides.

[0030] The inner cavity of the heating plate 52 is evenly provided with through openings, the upper surface of the heating plate 52 extends to the inside of the receiving bottom frame 41, the side of the control inner plate 53 away from the air inlet end 6 is fixedly connected to the inner cavity of the protective drum 45 through a wire, and the top of the outer surface of the wall-attached hollow plate 51 is fixedly connected to the lower surface of the receiving bottom frame 41. The top of the internal socket 48 extends to the inside of the receiving bottom frame 41, one side of the outer surface of the protective drum 45 is slidably connected to the inner wall of the pressure-maintaining outer box 11 through an auxiliary roller 47, and the other side of the outer surface of the protective drum 45 is slidably connected to the outer surface of the exhaust component 3, and both ends of the connecting wire 46 extend to the outside of the pressure-maintaining outer box 11. The bottom end of the support frame plate 49 is fixedly connected to the bottom of the inner wall of the receiving bottom frame 41, the inside of the closed cover plate 43 is clamped with the top of the receiving bottom frame 41, the outer surface of the receiving bottom frame 41 is slidably connected to the inner wall of the pressure-maintaining outer box 11, and the outer surface of the heating plate 52 is fixedly connected to the inner wall of the wall-attached hollow plate 51.

[0031] Before using the device to perform circuit board inspection, open the closed rotating plate 12, then use the pulling handle 44 to pull the containing component 4 out of the interior of the pressure-maintaining outer box 11, and when the containing bottom frame 41 is pulled out to the frontmost position, lift up the closed cover 43, and then place the circuit board on top of the supporting frame plate 49, and then dock the circuit board with the internal socket 48. After the circuit board is powered on successfully, close the closed cover 43 and the containing bottom frame 41, and then push the containing component 4 into the interior of the pressure-maintaining outer box 11 to complete the work of placing the circuit board.

[0032] When power is supplied, the interior of the pressure-maintaining outer box 11 is pressurized through the drainage devices 2 on both sides. After the interior of the pressure-maintaining outer box 11 is pressurized, it enters the interior of the wall-attached hollow plate 51 through the air inlet end 6, and then the airflow passes through the mesh of the heating electric plate 52 and enters the interior of the containing bottom frame 41. Since the heating electric plate 52 is working normally under the power supply and heating action of the control inner plate 53 at this time, the gas passing through the mesh of the heating electric plate 52 carries a certain amount of heat, thereby causing the interior of the containing bottom frame 41 to continue to heat up, simulating the working state of the circuit board in a high temperature environment.

[0033] Example 2, please refer to Figure 1-Figure 9The present invention provides a technical solution: on the basis of the first embodiment, the air inlet end 6 comprises a guide sleeve 61, the inner wall of the guide sleeve 61 is slidably connected with an inner slide 62, the outer surface of the inner slide 62 is sleeved with a gasket sleeve 63, and the inner cavity of the inner slide 62 is evenly provided with guide grooves 64, the top of the inner slide 62 extends to the inside of the hollow plate 51 attached to the wall, and the gas inside the pressure-maintaining outer box 11 enters the inside of the hollow plate 51 attached to the wall through the air inlet end 6 under the action of air pressure. The outer surface of the guide sleeve 61 is fixedly connected to the side of the outer surface of the hollow plate 51 attached to the wall away from the protection drum 45 through the through hole, the outer surface of the inner slide 62 is slidably connected to the inner wall of the guide sleeve 61, and the outer surface of the gasket sleeve 63 and the inner wall of the guide sleeve 61 are pressed against each other.

[0034] The exhaust component 3 includes a center partition 31, and guide grooves 32 are evenly opened on the left and right sides of the outer surface of the center partition 31, and docking vents 33 are evenly opened in the inner cavity of the center partition 31. The back of the inner cavity of the center partition 31 is fixedly connected to the external exhaust pipe 34 through a connecting pipe. The closed cover plate 43 is attached to one side of the center partition 31 and has an exhaust groove, which is connected to the docking vent 33, and then the exhaust gas is discharged through the external exhaust pipe 34.

[0035] The drainage device 2 includes a veneer side shell 21, and a blower 22 is fixedly connected to the side of the inner cavity of the veneer side shell 21 away from the pressure-maintaining outer box 11 through a through hole. A propulsion cylinder 24 is evenly arranged in the middle of the inner wall of the veneer side shell 21, and a traction rod 25 is slidably connected to the inner wall of the propulsion cylinder 24. A sliding brush plate 26 is fixedly connected to the back of the outer surface of the traction rod 25. A drainage rail 23 is evenly arranged on the back of the inner cavity of the veneer side shell 21. The drainage rail 23 is located at the air inlet inside the veneer side shell 21 and is installed with a filter screen. The sliding brush plate 26 has the same area as the filter screen, and a brush structure is arranged on the side of the sliding brush plate 26 that is in contact with the filter screen. There are two drainage devices 2. The end of the drainage rail 23 away from the veneer side shell 21 is fixedly connected to the back of the inner cavity of the pressure-maintaining outer box 11, the outer surface of the sliding brush plate 26 is slidably connected to the back of the inner wall of the veneer side shell 21, and the outer surface of the veneer side shell 21 is fixedly connected to the side of the pressure-maintaining outer box 11.

[0036] When the pressure-maintaining outer box 11 is pressurized, the air pressure will push the inner slide 62 toward the inside of the hollow plate 51 attached to the wall. At this time, the bottom end of the inner slide 62 drives the gasket sleeve 63 to slide, but the gasket sleeve 63 is restricted by the guide sleeve 61, so the guide sleeve 61 is compressed, and then the guide groove 64 of the inner slide 62 extends into the inside of the hollow plate 51 attached to the wall. At this time, the gas can enter the inside of the hollow plate 51 attached to the wall through the guide groove 64. When the pressure inside the pressure-maintaining outer box 11 is reduced, the air pressure is not enough to push the inner slide 62. At this time, the guide groove 64 of the inner slide 62 will be closed by the gasket sleeve 63 to prevent the gas inside the hollow plate 51 from flowing back.

[0037] The middle partition 31 guides the auxiliary roller 47 on one side of the protective drum 45 to slide through the guide grooves 32 on both sides. After the containing part 4 is inserted into the pressure-maintaining outer box 11, exhaust will be carried out through the side grooves of the closed cover plate 43. Since the side grooves of the closed cover plate 43 are always connected to the docking vent 33 of the middle partition 31 when the device is in working state, the middle partition 31 can discharge the gas inside the containing part 4 to the rear through the external exhaust pipe 34.

[0038] The blower 22 pressurizes the interior of the veneer side shell 21 so that the high-pressure gas can flow to the interior of the pressure-maintaining outer box 11 through the drainage rail 23. Since impurities in the air will affect the cleanliness inside the device, a dust screen is installed at the air inlet of the drainage rail 23. When the blower 22 is working, the propulsion cylinders 24 on the upper and lower sides drive the sliding brush plates 26 to move through the traction rods 25, so that the sliding brush plates 26 are misaligned with the air inlet of the drainage rail 23, thereby opening the drainage rail 23 and allowing the blower 22 to ventilate and pressurize normally. After the work is completed, the sliding brush plates 26 block the drainage rail 23, and the propulsion cylinder 24 drives the sliding brush plates 26 to slide up and down through the traction rods 25 to wipe the filter plate part of the drainage rail 23.

[0039] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
