Description

Technical Field

[0001] The present application relates to the technical field of a detection device for an aging board, and in particular to a detection device for an aging board. Background Art

[0002] The aging board is inserted into the testing device to test the connection performance and voltage resistance of the aging board.

[0003] The existing Chinese patent publication number is CN212483771U, which discloses a high-voltage test fixture, including a base, a detection mechanism and a high-voltage test circuit unit; the detection mechanism is arranged on the base and is used to detect the PCB circuit board, and the input end of the detection mechanism is provided with a solder structure; the high-voltage test circuit unit is arranged in the base, and the high-voltage test circuit unit is electrically connected to the detection mechanism.

[0004] Compared with the PCB fixtures in the prior art, the above-mentioned high-voltage test fixture cannot test the high-voltage resistance value between the PCB board networks, nor can it detect the high-voltage breakdown resistance value between the PCB board circuits and the substrate (aluminum sheet), resulting in a technical problem of low practicality. The high-voltage test fixture provided by the embodiment of the utility model adopts a high-voltage test circuit unit to make the voltage resistance value between the PCB circuit board networks reach 3000V, and adopts a detection end with a solder structure at the tail to detect the high-voltage breakdown resistance value between the PCB circuit board and the substrate (aluminum). At the same time, a switch is used to directly control the high-voltage test circuit unit, which has a simple structure and is easy to maintain and operate, which is conducive to improving the production efficiency of the fixture. However, the above-mentioned high-voltage test fixture has some shortcomings, such as: the PCB circuit board is first placed on the probe component, and then the PCB circuit board is pressed by the clamping component. The pressure plate will cause displacement during the process of pressing the PCB circuit board, which affects the test results of the PCB circuit board, and needs to be improved. Summary of the Invention

[0005] The purpose of this application is to provide a detection device for aging boards in order to improve the stability of the placement of the aging boards.

[0006] The present application provides a detection device for an aging board, which adopts the following technical solution: it includes a base, the base is connected to a test board, a side of the test board away from the base is connected to a plurality of telescopic detection needles, the base is slidably connected to a mounting plate, the base is connected to a first driving member for driving the mounting plate to slide toward or away from the test board, the mounting plate is provided with a mounting groove for the aging board to be snapped into, the mounting plate is provided with a channel for the plurality of telescopic detection needles to pass through, the mounting groove is connected to the channel, the inner walls on both sides of the mounting groove facing each other are connected to a plurality of limit blocks for abutting the aging board, and the channel is located between the limit block and the telescopic detection needle.

[0007] By adopting the above technical solution, the aging board is inserted into the installation slot, and the outer surface of the aging board is aligned with the inner wall of the installation slot and several limit blocks. The inner wall of the installation slot plays a role in initially positioning the aging board. The first driving member drives the installation plate to slide toward the test plate until the aging board contacts the telescopic detection needle. The aging board is clamped by the telescopic detection needle and several limit blocks. The inner wall of the installation slot, the several telescopic detection needles and the several limit blocks restrict the movement of the aging board, thereby improving the stability of the aging board placement.

[0008] Optionally, the mounting plate is connected to a positioning block for abutting against the aging plate, and the positioning block is located between two opposing inner walls of the mounting groove.

[0009] By adopting the above technical solution, the aging board is inserted into the installation slot until one side of the aging board abuts against the positioning block. The positioning block plays a positioning role in the placement of the aging board, thereby improving the placement accuracy of the aging board.

[0010] Optionally, the base is slidably connected to a carrier plate, the mounting plate is located between the carrier plate and the test plate, and a plurality of pressing columns for pressing the aging board are connected to the side of the carrier plate close to the mounting plate. The first driving member is used to drive the carrier plate to slide toward or away from the test plate, and the carrier plate drives the mounting plate to slide toward or away from the test plate through the connecting structure.

[0011] By adopting the above technical solution, the first driving member drives the carrier plate to slide, and the mounting plate slides with the carrier plate through the connecting structure. The sliding of the mounting plate is connected with the carrier plate through the connecting structure, which reduces the drive and increases the relevance of the overall structure.

[0012] Optionally, the connection structure includes two connecting plates connected to the carrier plate and a lifting plate connected to the connecting plates, the lifting plates are used to abut against the mounting plate, and the mounting plate is located between the lifting plates and the carrier plate.

[0013] By adopting the above technical solution, the first driving member drives the carrier plate to slide in the direction close to the test plate, the lifting plate is separated from the mounting plate, and the mounting plate slides in the direction close to the test plate under the influence of gravity until the aging plate abuts against a number of telescopic detection pins. The number of telescopic detection pins support the aging plate, and the aging plate stops descending. The first driving member drives the carrier plate to continue to slide in the direction close to the test plate until the pressing column abuts against the aging plate. The inner wall of the mounting groove, the number of telescopic detection pins, the number of limit blocks and the number of pressing columns limit the movement of the aging plate, thereby improving the stability of the placement of the aging plate. The first driving member drives the carrier plate to slide in the direction away from the test plate, and the lifting plate moves with the movement of the carrier plate until the lifting plate abuts against the mounting plate and drives the mounting plate to slide in the direction away from the detection plate. The movement of the mounting plate is connected together through the carrier plate, the connecting plate and the lifting plate, which reduces the drive and increases the correlation of the overall structure.

[0014] Optionally, the base is connected to a plurality of first guide columns and a plurality of second guide columns, the carrier plate is provided with a first guide hole for slidingly cooperating with the corresponding first guide column, and the mounting plate is provided with a second guide hole for slidingly cooperating with the corresponding second guide column.

[0015] By adopting the above technical solution, when the carrier plate slides, the first guide column and the first guide hole slide together to guide and limit the sliding of the carrier plate, thereby improving the sliding stability of the carrier plate; when the mounting plate slides, the second guide column and the second guide hole slide together to guide and limit the sliding of the mounting plate, thereby improving the sliding stability of the mounting plate.

[0016] Optionally, the base is connected to a plurality of first stop posts for abutting against the carrier plate and a second stop post for abutting against the mounting plate.

[0017] By adopting the above technical solution, the first stop column limits the sliding of the carrier plate to prevent the pressing column from damaging the aging plate, and the second stop column limits the sliding of the mounting plate to prevent the telescopic detection needle from damaging the aging plate, or the aging plate from damaging the telescopic detection needle.

[0018] Optionally, the pressing column is connected to a buffer block for abutting against the aging board.

[0019] By adopting the above technical solution, the buffer block can be used to absorb impact energy and reduce damage to the aging board.

[0020] Optionally, the outer peripheral surface of the pressing column is slidingly connected to a ring plate, the pressing column is provided with a cavity, the pressing column is provided with an air nozzle connected to the cavity, the ring plate is connected to a first airbag for covering the cavity, the cavity is connected to the first airbag, the outer peripheral surface of the pressing column is connected to a second airbag, the second airbag is provided with several connecting pipes connected to the cavity, the pressing column is connected to a pressing plate for pressing the second airbag, and the pressing plate is connected to the ring plate through an elastic member.

[0021] By adopting the above technical solution, the first driving member drives the pressing column to slide in the direction close to the aging plate, the first airbag abuts the aging plate, the first airbag is compressed and slides with the ring plate along the length direction of the pressing column, and the elastic member is compressed to produce elastic deformation. During the deformation process of the first airbag, the gas in the first airbag is transferred to the second airbag through the connecting pipe, thereby reducing the air pressure in the first airbag, which is beneficial to the deformation of the first airbag and avoids the first airbag from being damaged due to excessive pressure, thereby increasing the service life of the first airbag. When the first airbag is separated from the aging plate, the elastic member elastically resets, and the elastic member forces the first airbag and the ring plate to reset. During the reset process of the ring plate, the pressing plate and the ring plate squeeze the second airbag, so that the gas in the second airbag is transferred to the first airbag through the connecting channel to achieve the reset of the first airbag for the next work. The first airbag and the air are both soft structures, which effectively reduce the damage to the aging plate and play a protective role on the aging plate. The inflation and exhaust of the first airbag and the second airbag are connected together through the elastic member, the pressing plate, the connecting pipe and the first driving member, which reduces the drive and increases the relevance of the overall structure.

[0022] Optionally, the ring plate is connected to a control button for abutting against the pressing plate, and the control button is electrically connected to the first driving member.

[0023] By adopting the above technical solution, when the control button moves to the pressing plate, it means that the first airbag is working in place. At this time, the control button can trigger the first driving member to stop working, preventing the first airbag from being over-pressed, thereby protecting the aging board.

[0024] Optionally, the mounting plate is slidably connected to a sliding plate, the sliding plate is connected to a stripping plate for abutting against the aging plate, and the mounting plate is connected to a second driving member for driving the sliding plate to slide toward or away from the positioning block.

[0025] By adopting the above technical solution, after the aging board is inspected, the second driving member drives the sliding plate to slide in the direction away from the positioning block, that is, the stripping plate also slides in the direction away from the positioning block. The stripping plate abuts against the aging board and drives the aging board to exit the installation slot, thereby improving the disassembly efficiency of the aging board.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The inner wall of the installation groove, several telescopic detection needles, several limit blocks and several pressing columns limit the movement of the aging board, thereby improving the stability of the aging board placement.

[0028] 2. The movement of the mounting plate is connected through the carrier plate, the connecting plate and the lifting plate, which reduces the drive and increases the correlation of the overall structure. BRIEF DESCRIPTION OF THE DRAWINGS
