Description

Technical Field

[0001] This invention relates to the field of testing equipment, and more particularly to a quick-change connection mechanism for a hardware testing system. Background Technology

[0002] With the development of technology, industrial automation is becoming increasingly sophisticated, and automated equipment is becoming more and more advanced. Currently, the common practice for companies is to develop separate automated processing or testing equipment for different products. For example, a series of products within the same product series also requires the development of a series of corresponding automated equipment. This approach has the following problems: each automated piece of equipment is only compatible with one product, requiring manufacturers to invest heavily in design and production. Some companies, in an effort to reduce costs, have begun to move towards modularity and replaceability, but this typically involves changing the product fixtures, which does not significantly reduce costs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a quick-change connection mechanism for a hardware testing system that is simple in structure, quick to replace, low in cost, and meets the application scenarios of multi-purpose use.

[0004] The technical solution adopted in this invention is that this invention includes a base support;

[0005] A product tray that is slidably fitted onto the base bracket and used to support the product to be tested;

[0006] A test backplate that is plugged into the base bracket and used to connect the product under test on the product tray to the adapter plate;

[0007] An adapter plate mounting assembly is used to install the adapter plate and to drive the adapter plate into or out of the test back plate. The adapter plate mounting assembly is slidably fitted onto the base bracket.

[0008] A plug-in / plug-out assist device is used to drive the product tray to move toward or away from the test backplate. When the plug-in / plug-out assist device drives the product tray to move toward the test backplate, the interface on the product under test is connected to the interface on the test backplate. When the plug-in / plug-out assist device drives the product tray to move away from the test backplate, the interface on the product under test is disconnected from the interface on the test backplate.

[0009] As can be seen from the above scheme, the product tray on the base bracket is designed with a sliding fit. When the insertion / removal assist device moves the product tray towards the test backplate, the interface on the product under test (DUT) connects with the interface on the test backplate. When the insertion / removal assist device moves the product tray away from the test backplate, the interface on the DUT disconnects from the interface on the test backplate. The insertion / removal assist device can move the DUT placed on the product tray towards the test backplate, connecting the DUT to the test backplate. On the other side of the test backplate, an adapter plate connects via an adapter... The board mounting assembly moves and connects to the test backplane, enabling quick connection between the product under test and the adapter board, thus facilitating rapid testing. Its simple structure and relatively low implementation cost further simplify this process. Additionally, the test backplane is inserted into the base bracket. When testing different products, the product tray and adapter board can be pulled out and disconnected from the test backplane for quick replacement, meeting the testing needs of various products. This extremely fast replacement capability satisfies the requirements of multi-functional applications. Furthermore, the adapter board can also be quickly replaced according to different needs, making this invention more adaptable.

[0010] Furthermore, a cover plate is hinged to the base bracket, and when the quick-change connection mechanism of the hardware testing system is in operation, the cover plate closes onto the product tray.

[0011] As can be seen from the above solution, the cover can prevent operators from coming into contact with the inside of the test product and also ensure safety.

[0012] Furthermore, the base support includes a mounting base plate and a bracket fixedly mounted on the mounting base plate. Two sets of support sliders are symmetrically arranged on the bracket, and a drag rail is symmetrically arranged on the product tray, which slides and engages with the two sets of support sliders respectively. The product tray slides on the base support through the engagement of the support sliders and the drag rails.

[0013] As can be seen from the above scheme, the sliding cooperation between the drag rail and the support slider allows the product under test to be easily pulled out or inserted into the test backplate. Furthermore, the contact area between the drag rail and the support slider is coated with lubricant, which ensures smoother movement of the product tray when the drag rail moves. This ensures accurate and rapid matching and connection or disconnection of the connectors on the product under test and the connectors on the test backplate, thus guaranteeing the reliability and stability of the test.

[0014] In addition, two opposing slots are symmetrically arranged on the base bracket, and the test back plate is fitted into the slots and fixed by locking pins.

[0015] As can be seen from the above scheme, the slot design facilitates the quick positioning and fixing of the test backplate, while the locking pin (not shown in the attached diagram of the manual) can quickly tighten and unlock the test backplate, facilitating the quick replacement of the test backplate.

[0016] Furthermore, the adapter plate mounting assembly includes an adapter plate mounting frame, on which a manual locking device is provided. The manual locking device includes a drive rod, a positioning locking rod, and a moving guide rod. The positioning locking rod and the moving guide rod are of equal length. One end of the drive rod has two holes along its length. The positioning locking rod and the moving guide rod are rotatably engaged with one of the holes. The positioning locking rod is located at the outermost end of the drive rod. The adapter plate mounting frame has a guide groove, and the moving guide rod is fitted into the guide groove. The positioning locking rod is located around the guide groove. The mounting base plate has an adapter plate moving guide rail that slides with the adapter plate mounting frame. The adapter plate moving guide rail has a locking positioning groove, and the positioning locking rod is locked into the locking positioning groove. The adapter plate has a connector, which is connected to the test backplate.

[0017] As shown in the above scheme, the adapter plate is mounted on the adapter plate mounting bracket, which slides with the adapter plate moving guide rail on the mounting base plate. During the sliding process, the connector on the adapter plate connects with the connector on the test backplate to conduct electrical signals, thereby testing the product under test at the rear of the test backplate. The manual locking device allows the adapter plate mounting bracket and the adapter plate to move smoothly and stably, ensuring the stable and reliable connection between the adapter plate and the test backplate. During the movement of the manual locking device, the positioning locking rod engages with the locking positioning groove on the adapter plate moving guide rail, while the moving guide rod is located in the guide groove hole. When the drive rod is manually swung, the positioning locking rod acts as a hinge point. Utilizing the lever principle, the moving guide rod drives the adapter plate mounting bracket to move accordingly, thereby connecting or disconnecting the adapter plate from the test backplate, achieving quick connection or disconnection of the adapter plate. This facilitates the rapid replacement of the adapter plate and the test backplate, improving efficiency.

[0018] In addition, a cooling fan is provided on the cover plate for cooling the product under test, and the cover plate is made of transparent material.

[0019] As can be seen from the above solution, making the cover plate transparent allows operators to observe the entire process of the product under test (DUT) connecting to the test backplane. If any abnormality is detected, the operation can be stopped at any time to avoid damage to the product and the backplane connection plate. The cooling fan can quickly dissipate heat from the DUT, preventing the product's performance from being affected during testing.

[0020] More specifically, the bracket is symmetrically provided with two hinged upright plates. The insertion and removal assist device includes a handle, a cover plate mounting claw, a movable hinge shaft, and a drag rail connecting ear. One end of the handle is hinged to the hinged upright plate. A hinge point is provided on the periphery of the position where the handle is hinged to the hinged upright plate, which is hinged to the drag rail connecting ear. The other end of the drag rail connecting ear is hinged to the drag rail. A first movable guide groove is provided on the handle. A second movable guide groove is provided on the hinged upright plate. One end of the movable hinge shaft is fixed to the cover plate mounting claw, and the other end passes through the second movable guide groove and the first movable guide groove in sequence. The cover plate is installed on the outer end of the cover plate mounting claw. A vertical guide groove is also provided on the hinged upright plate. A guide hinge shaft is provided on the cover plate mounting claw, and the guide hinge shaft is fitted into the vertical guide groove.

[0021] As shown in the above scheme, the hinged upright plate is fixed to the bracket, and one end of the handle is hinged to the hinged upright plate. The first movable guide groove on the handle and the second movable guide groove on the cover plate mounting claw cooperate with each other. The cover plate mounting claw achieves the closing and opening of the cover plate through two movable connection points formed by the movable hinge shafts in the first and second movable guide grooves and the guide hinge shafts in the vertical guide groove. When the handle is pressed down, the handle rotates along the hinge point where the handle is hinged to the hinged upright plate. At this time, the movable hinge shafts in the first and second movable guide grooves and the guide hinge shafts in the vertical guide groove together drive the cover plate mounting claw and the handle to press down together, so that the cover plate is tightly closed on the product to be tested. When the handle is pulled up, the cover plate mounting claw follows the upward movement and is also opened at the same time. In addition, a hinge point is provided on the periphery of the position where the handle is hinged to the hinged upright plate, which is hinged to the drag rail connecting ear. Through the drag rail connecting ear, during the pressing down of the handle, the drag rail... The connecting lug drives the slide rail, which in turn moves the product tray toward the test backplate. When the handle is pressed down, the connector on the product under test (DUT) on the product tray connects with the connector on the test backplate. When the handle is pulled up, the connecting lug drives the slide rail, which in turn moves the product tray away from the test backplate. When the handle is pulled up, the connector on the DUT on the product tray disconnects from the connector on the test backplate. Through the coordination of the hinged upright plate and the insertion / removal assist device, the handle, cover, and product tray can move simultaneously. The product tray moves the DUT, thus enabling the linkage of three components with a single component action. When the cover is closed, the product tray connects the DUT to the test backplate; when the cover is opened, the product tray disconnects the DUT from the test backplate. This ensures both the reliability and safety of the test, while also significantly reducing the structural complexity and cost of the equipment.

[0022] Finally, two adapter plates are provided on the adapter plate mounting bracket.

[0023] As can be seen from the above solution, two adapter plates can be installed on the adapter plate mounting bracket at the same time, which can meet the application scenarios of one or two adapter plates, thus improving the applicability of the present invention. Attached Figure Description

[0044] The adapter plate mounting bracket 13 is provided with two adapter plates 3.

[0045] The working process of this invention is as follows:

[0046] 1) According to the test requirements of the product under test, the test backplate and adapter plate are matched and replaced. At this time, pull up the handle 23. The handle drives the drag rail connecting ear 26 to move. The drag rail connecting ear 26 drives the drag rail 11 to move away from the test backplate. The drag rail 11 drives the product tray 2 to move. The product connector on the product tray is disengaged from the connector on the test backplate. At the same time, manually pull the drive rod 14 of the manual locking device. The drive rod drives the adapter plate mounting frame to move away from the test backplate. At this time, the test backplate is disconnected from the adapter plate on the adapter plate mounting frame. At this time, open the locking pin in the slot (not shown in the attached diagram of the manual) to replace the test backplate. If the adapter plate needs to be replaced, the adapter plate can also be removed from the adapter plate mounting frame and replaced with the required adapter plate.

[0047] 2) Place the product to be tested into the product tray 2 and fix it in place using the product positioning post 31;

[0048] 3) Pulling handle 23 causes it to press down, which in turn moves the slide rail 11 via the drag rail connecting lug 26. The slide rail 11 moves the product tray towards the test back plate 4. When the product tray 2 moves to the test back plate 4, the connector on the product under test connects with the connector on the test back plate 4, achieving electrical conductivity. Simultaneously, the movable hinge shaft 25 causes the cover plate mounting claw 24 to press down, covering the product under test to prevent accidents during testing and ensure the smooth and accurate conduct of the test. When the handle is pulled up, the above actions are reversed, and the cover plate opens, removing the product tray from the test back plate. When testing is required... Try different products and repeat step 1 above. At this point, the test backplate can be replaced. On the other side of the test backplate, push the adapter plate mounting assembly 5 into the adapter plate moving guide rail 18. When the positioning locking rod 15 reaches the clamping positioning groove 19, the positioning locking rod 15 is clamped in the clamping positioning groove 19. Under the action of the drive rod 14, the moving guide rod 16 pushes the adapter plate mounting bracket 13 to continue moving towards the test backplate until the connector on the adapter plate 3 is connected and conductive with the connector on the test backplate. When the adapter plate needs to be replaced, reverse the operation and pull the adapter plate mounting bracket out of the adapter plate moving guide rail 18 to replace the adapter plate.

[0049] 4) Test the product to be tested.

[0050] d. After the test is completed, open the handle, take out the tested product, and then put the untested product into the test fixture. Repeat the above steps.
