Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing fixture technology, and more particularly to a floating testing device. Background Technology
[0002] Testing products with electronic circuits typically involves multiple steps, including programming, general functional testing, and aging tests. During testing, the product is first placed in a corresponding fixture, its interface is aligned with the fixture, and the product is then pressed firmly to maintain stable contact. Finally, programming, functional testing, and aging tests are performed. Using fixtures helps to confine the product in a specific position, preventing loosening and displacement during testing and improving product stability.
[0003] When loading a product into the fixture, the product is gripped by the jaws and placed into the fixture under their hold. This assembly process can easily result in hard contact between the product and the fixture, causing the product to endure significant assembly pressure and potentially leading to assembly damage.

[0034] The following will refer to the appendices in the embodiments of this application. Figure 1 To be continued Figure 5The technical solutions in the embodiments of this application are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0035] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0036] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.
[0037] like Figure 1-3 The floating test apparatus shown includes a main fixture body 1, a floating sub-fixture 2, a docking plug 3, a test component 4, and at least two spring-loaded latches 5. The floating sub-fixture 2 is mounted on the main fixture body 1 and is elastically movable relative to the main fixture body 1. The two spring-loaded latches 5 are mounted on the main fixture body 1 and located at opposite ends of the floating sub-fixture 2. When the product under test is placed into the fixture frame 21 of the floating sub-fixture 2, the fixture frame 21 springs upward, and the spring-loaded latches 5 press the product under test onto the floating sub-fixture 2. The docking plug 3 is mounted on the main fixture body 1 and located below the floating sub-fixture 2. The docking plug 3 and the product under test are used for power supply, communication, and test control.
[0038] In this invention, a floating fixture 2 is provided on the main fixture body 1. The floating fixture 2 can be elastically raised and lowered relative to the main fixture body 1. Thus, when the product to be tested is placed on the floating fixture 2 by the transport component 6, the floating fixture 2 can elastically support the product to be tested, so that a flexible contact is formed between the floating fixture 2 and the product to be tested, reducing the pressure on the product to be tested, avoiding damage to the product to be tested during test assembly, and effectively protecting the product.
[0039] Meanwhile, during floating assembly, at least two elastic clips 5 are used to hold the product under test in place. During the test, the floating fixture 2 applies stable pressure to the product under test to maintain its stability during the test.
[0040] More importantly, the upward rebound force of the floating fixture 2 ensures that the product under test (DUT) on the floating fixture 2 maintains pressure contact with the test assembly 4. The DUT adheres tightly to the test assembly 4, and all DUTs maintain a consistent distance from the test assembly 4, eliminating accumulated tolerances from parts assembly. For example, when the test module 42 on the test assembly 4 is a coil, the DUT adheres tightly to the coil, and different DUTs maintain the same distance from the coil, ensuring that the DUTs have the same distance standard. This eliminates the impact of assembly tolerances on the test, making the test standardized and precise.
[0041] In some embodiments of the floating sub-fixture 2, such as Figure 4 As shown, the floating sub-fixture 2 includes a fixture frame 21, several guide connectors 22, and several elastic members 23. The fixture frame 21 serves as the load-bearing structure for the product under test, and the transport assembly 6 places the product under test onto the fixture frame 21. The upper end of the guide connector 22 slidably passes through the fixture frame 21, and the lower end of the guide connector 22 is connected to the main fixture body 1. One end of the elastic member 23 abuts against the fixture frame 21, and the other end abuts against the main fixture body 1. The guide connector 22 is connected to the main fixture body 1 through its lower end. The fixture frame 21 and the guide connector 22 slide and move in a vertical manner, and the fixture frame 21 becomes elastic under the action of the elastic member 23. When the fixture frame 21 is under pressure, that is, when the transport component 6 puts the product to be tested into the fixture frame 21, the fixture frame 21 moves downward and rebounds upward under the action of the elastic element 23. The fixture frame 21 can maintain appropriate pressure on the product to be tested, so that the product to be tested on the fixture frame 21 can be pressed by the elastic buckle 5.
[0042] Specifically, the guide connector 22 includes a nut and a guide rod. The nut is located at one end of the guide rod to prevent the guide connector 22 from slipping off, or in other words, to prevent the fixture frame 21 from slipping upwards. The other end of the guide rod has a connecting part. The nut is located above the fixture frame 21, and the guide rod slides through the fixture frame 21 to form a lifting engagement with the fixture frame 21. The connecting part is connected to the main fixture body 1.
[0043] The elastic element 23 is specifically a compression spring, which is sleeved on the guide rod and located between the fixture frame 21 and the main fixture body 1. It can also be located at other positions besides the guide rod.
[0044] In addition, to guide the jig frame 21 in raising and lowering and improve the accuracy of the jig frame 21, several guide pins 24 can be set on the jig frame 21, and several guide holes corresponding to the guide pins 24 can be set on the main jig body 1. The guide pins 24 are inserted into the guide holes and form a sliding fit with the guide holes, thereby guiding the jig frame 21 to raise and lower precisely and improving the accuracy of the docking between the product under test and the docking plug 3.
[0045] Furthermore, the fixture frame 21 is also provided with several limiting blocks 25. The limiting blocks 25 guide the product under test into the fixture frame 21 and limit the position of the product under test on the fixture frame 21, thereby further improving the accuracy of the product under test and the docking plug 3.
[0046] In some embodiments of the elastic clip 5, such as Figure 5 As shown, the elastic buckle 5 includes a mounting member 52, a torsion spring, and a snap fastener 51. The mounting member 52 is mounted on the main fixture body 1. The snap fastener 51 is rotatably mounted on the mounting member 52, with its hook portion positioned upwards and facing inwards towards the floating sub-fixture 2. The torsion spring is mounted on the mounting member 52 and connected to the snap fastener 51 to drive it to fasten towards the product to be tested.
[0047] In some embodiments of the floating test apparatus, such as Figure 1 Figure 2 As shown, the floating test device also includes a handling component 6 for picking up and placing the product under test.
[0048] like Figure 3 As shown, the conveying assembly 6 includes a gripper mechanism 61, which includes a gripper power element 612 and two grippers 611. The gripper power element 612 is connected to the grippers 611 and drives the grippers 611 to perform opening and closing actions.
[0049] The elastic buckle 5 can be an active action, performing hooking or unhooking actions under the drive of some power components. Specifically, it is set to drive the buckle 51 to rotate forward or reverse by a motor or cylinder.
[0050] The elastic buckle 5 can also be a passive action. Specifically, such as... Figure 5 As shown, the lower end of the inverted buckle 51 is provided with a toggle part 511. When the gripper mechanism 61 picks up the tested product from the fixture frame 21, the gripper 611 opens to the position corresponding to the toggle part 511. Thus, when the gripper mechanism 61 descends, the gripper 611 applies pressure to the toggle part 511, thereby opening the inverted buckle 51 outward, forming a passive action of the elastic buckle 5, which opens as the gripper mechanism 61 descends.
[0051] Alternatively, a guide slope can be provided on the inner side of the hook, so that the product to be tested can abut against the guide slope and open the inverted buckle 51 during the process of placing it into the fixture frame 21.
[0052] For transport component 6, such as Figure 3 As shown, it also includes a clamping mechanism 62 capable of lifting and lowering. The clamping mechanism 62 is disposed between two grippers 611 and is used to maintain the height of the product to be tested when picking up and placing the product to be tested. When the product to be tested is placed into the fixture frame 21, the gripper mechanism 61 places the product to be tested into the fixture frame 21, the elastic buckle 5 is not open, and the product to be tested is above the elastic buckle 5. The conveying component 6 continues to descend, applying pressure to the actuating part 511 to open the inverted buckle 51 outward, and the product to be tested falls completely from the elastic buckle 5 onto the fixture frame 21. During the process of removing the tested product, before the gripper 611 opens the spring clip 5, the clamping mechanism 62 abuts against or approaches the tested product. As the conveying component 6 descends, the gripper 611 gradually opens the spring clip 5 until the spring clip 5 disengages from the tested product, and the fixture frame 21 springs upward. At this time, the clamping mechanism 62 abuts against or approaches the tested product, which can limit the excessive bouncing of the tested product and keep it stable. Afterward, the clamping mechanism 62 rises, that is, the clamping plate 621 rises below, and the tested product rises accordingly. The tested product passes over the spring clip 5 and the fixture frame 21 rises to its highest position. Finally, the conveying component 6 rises, and the gripper 611 grabs the tested product.
[0053] In some embodiments of the clamping mechanism 62, such as Figure 3 As shown, the clamping mechanism 62 includes a clamping drive element 622 and a clamping plate 621. The clamping drive element 622 is disposed between two grippers 611, and the clamping plate 621 is disposed below the clamping drive element 622. The clamping plate 621 is located in the structure where the product abuts and is used to apply pressure to the product when picking up or putting down the product.
[0054] Specifically, the clamping mechanism 62 also includes a mounting plate, which is located at the bottom of the gripper mechanism 61, specifically at the bottom of the gripper power element 612. The clamping drive element 622 is mounted on the mounting plate. Alternatively, the clamping drive element 622 can be directly mounted on the bottom of the gripper power element 612. The clamping plate 621 is located below the clamping drive element 622 and is connected to it. The clamping drive element 622 drives the clamping plate 621 to move up and down.
[0055] The gripper drive element 612 and the clamping drive element 622 can be cylinders, wherein the gripper drive element can be a pneumatic finger and the clamping drive element 622 can be a pneumatic push rod.
[0056] In some test implementation examples of the product under test, such as Figure 2As shown in Figure 3, test component 4 is required to test the product under test. Specifically, test component 4 includes a moving mechanism and a test module 42. The test module 42 is set on the moving mechanism and is used to test the product on the floating sub-gig 2.
[0057] Specifically, the moving mechanism includes a flipping drive mechanism and a flipping frame 41. The test module 42 is mounted on the flipping frame 41, which is rotatably mounted on the main fixture body 1. The flipping frame 41 drives the test module 42 to flip above the floating sub-fixture 2. The flipping drive mechanism is driven by the flipping frame 41 to drive the flipping frame 41 to flip. The flipping drive mechanism can be a cam mechanism, or a power element that drives the cam mechanism to swing, including the cam mechanism. The flipping drive mechanism can also be a motor that directly drives the flipping frame 41 to rotate or output rotary motion.
[0058] Of course, the moving mechanism can also be a two-dimensional moving platform or a three-dimensional moving platform, thereby driving the test module 42 to move and pressing the test module 42 against the product under test.
[0059] Specifically, test module 42 can be a charging induction test module, where the product under test is a product with a battery cell; it can also be a charging magnetotraction test module, where the product under test is a product capable of transmitting or receiving electromagnetic signals; or it can be a wireless communication test module, where the product under test is a product capable of wireless communication.
[0060] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
