Description

Technical Field

[0001] This utility model relates to the field of chip testing technology, and more specifically, to a device for carrying a test board. Background Technology

[0002] Currently, chip testing requires placing the test board in a testing device. Due to the large size of the test board, it is typically placed in a carrier vehicle. After the vehicle is moved to a fixed position, the operator pushes the test board into the testing device for testing. However, because of the large size of the test board, the operator's manual pushing force can easily become uneven, causing the test board to collide with the testing device. This affects the test sockets inside the test board, leading to poor contact between the chip and the test socket, impacting testing efficiency and results. Utility Model Content

[0003] The technical problem to be solved by this utility model is that when the test board is manually pushed into the test device, uneven force is easily caused, which leads to collision between the test board and the test device, affecting the test efficiency and test results. In view of the above-mentioned defects of the prior art, a device for supporting the test board is provided.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A device for carrying a test board is constructed, comprising a vehicle body having a plurality of placement areas for placing the test board.

[0006] The load-bearing part is located on one side of the vehicle body;

[0007] The first rod is movably disposed on the bearing portion;

[0008] The second rod is provided corresponding to the first rod, and one end of the second rod is connected to the first rod;

[0009] When the first rod moves toward the placement area, it drives the second rod to push the test plate into the test device.

[0010] Furthermore, the supporting part is provided with a mounting hole, and the first rod body is provided with a rotating part, which is movably disposed within the mounting hole.

[0011] Furthermore, when the first rod moves toward the test plate placement area, the rotating part rotates within the mounting hole, causing the other end of the second rod to contact the test plate.

[0012] Furthermore, the first rod and the second rod are detachably or rotatably connected.

[0013] Furthermore, when the first rod body and the second rod body are detachably connected, the first rod body is provided with a fixing structure, and the second rod body is provided with a fixing hole; the fixing structure includes at least one fixing member and several through holes, the through holes being arranged on the first rod body; the fixing member passes through the through holes and is threadedly connected to the fixing holes.

[0014] Furthermore, the first rod body is rotatably connected to the second rod body, and a telescopic part is provided between the first rod body and the second rod body. The telescopic part is movably connected to the first rod body and the second rod body respectively, and the second rod body is movably connected to the first rod body.

[0015] Furthermore, the telescopic part includes a first telescopic rod and a second telescopic rod, one end of the first telescopic rod is rotatably connected to the first rod body, the other end is rotatably connected to one end of the second telescopic rod, and the other end of the second telescopic rod is slidably connected to the second rod body.

[0016] Furthermore, the first rod body is provided with a first rotating hole, one end of the first telescopic rod is provided with a first rotating column, and the other end is provided with a second rotating hole; the first rotating column is movably disposed in the first rotating hole; one end of the second telescopic rod is provided with a second rotating column, and the second rotating column is movably disposed in the second rotating hole; the second rod body is provided with a sliding groove, and the other end of the second telescopic rod is located in the sliding groove and is slidably connected to the sliding groove.

[0017] Furthermore, when the first rod rotates toward the placement area, the first rotating column rotates within the first rotating hole, the second rotating column rotates within the second rotating hole, and drives the second telescopic rod to slide within the groove.

[0018] Furthermore, the vehicle body has corresponding sliding structures on both sides, and each pair of sliding structures constitutes a placement area; and the length of the sliding structure is greater than the length of the test plate.

[0019] The beneficial effects of this invention are as follows: A support portion is provided on the side of the vehicle body relative to the testing device, and a first rod is provided at the support portion. By rotating the first rod, a second rod is moved toward the test board placement area, pushing the test board in the placement area into the testing device. This eliminates the need for the operator to manually push the test board, avoiding collisions between the test board and the testing device caused by excessive or uneven pushing force, which could lead to poor contact between the chip in the test socket and the test socket, thus improving testing efficiency and the accuracy of test results.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0038] This application is described in detail with reference to the schematic diagrams. When detailing the embodiments of this application, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to general proportions. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection claimed herein. In actual fabrication, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0039] After the test board carrier is moved to a fixed position, the operator will push the test board on the test board carrier into the test device. However, because the test board is large, the force of the operator pushing it manually is prone to unevenness and imbalance, which causes the test board to collide with the carrier, resulting in poor contact of the chip on the test board, affecting the test efficiency and test results.

[0040] Please refer to Figure 1 One embodiment of this application proposes a device for carrying a test board, including a vehicle body 1 with a plurality of placement areas 2 for placing test boards 7; a support part 3 located on one side of the vehicle body 1; a first rod 4 movably disposed on the support part 3; and a second rod 5 corresponding to the first rod 4, with one end connected to the first rod 4. When the first rod 4 moves toward the placement area 2, it drives the second rod 5 to push the test board 7 into the testing device 6. This eliminates the need for the operator to manually push the test board 7, avoiding collisions between the test board 7 and the testing device 6 due to excessive or uneven pushing force, which could lead to poor contact between the chip in the test socket and the test socket, thus improving testing efficiency and the accuracy of test results.

[0041] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0042] like Figure 1 As shown, in one embodiment, the device includes a vehicle body 1 with a plurality of placement areas 2 for placing test plates 7; a support part 3 located on one side of the vehicle body 1; a first rod 4 movably disposed on the support part 3; and a second rod 5 corresponding to the first rod 4, with one end connected to the first rod 4. When the first rod 4 moves toward the placement area 2, it drives the second rod 5 to push the test plate 7 into the testing device 6.

[0043] Specifically, the vehicle body 1 has multiple placement areas 2 for placing test boards 7. A support portion 3 is located on the side of the vehicle body 1 opposite to the testing device 6, i.e., the side away from the testing device 6. The testing device 6 can be a chip aging test chamber or a chip aging test equipment. A first rod 4 is movably connected to the support portion 3 and can rotate around the support portion 3. A second rod 5 is provided on the first rod 4, corresponding to the first rod 4. In one specific embodiment, two first rods 4 are provided on both sides of the vehicle body 1, and two second rods 5 are also provided, each located on a first rod 4. One end of each second rod 5 is connected to the first rod 4, and the other end faces the placement area 2. After the vehicle body 1 is moved to the testing device 6, the first rod 4 is rotated, causing the connected second rod 5 to contact the test board 7 located in the placement area 2. The second rod 5 gradually moves towards the testing device 6, pushing the test board 7, causing it to move within the placement area 2 until the test board 7 is pushed into the testing device 6. By rotating the first rod 4, the second rod 5 can be pushed into the test device 6. The operator does not need to manually push the test board 7, which can avoid the test board 7 from colliding with the test device 6 due to excessive or unbalanced pushing force, and prevent the chip in the test socket from making poor contact with the test socket, thereby improving test efficiency and the accuracy of test results.

[0044] It is worth mentioning that, Figure 1 This is only a schematic diagram of the first rod 4 and the second rod 5. In addition to the rod structure shown in the figure, the first rod 4 can also be a plate structure, a strip structure or other structures.

[0045] like Figures 2-4 As shown, in one embodiment, the bearing part 3 is provided with a mounting hole 301, and the first rod body 4 is provided with a rotating part 401, which is movably disposed in the mounting hole 301.

[0046] Specifically, the vehicle body 1 is provided with multiple supporting parts 3, each of which has a mounting hole 301, which is circular. The rotating part 401 of the first rod 4 is installed in the mounting hole 301 of the supporting part 3 and can rotate within the mounting hole 301. When the first rod 4 is rotated, the rotating part 401 can rotate within the mounting hole 301.

[0047] In one embodiment, when the first rod 4 moves toward the placement area 2, the rotating part 401 rotates within the mounting hole 301, causing the other end of the second rod 5 to contact the test plate 7.

[0048] Specifically, such as Figure 7As shown, when the first rod 4 moves toward the placement area 2, the rotating part 401 rotates within the mounting hole 301, causing the end of the second rod 5 to contact the test plate 7; wherein, the end is the end away from the first rod 4. After contacting the test plate 7, the first rod 4 continues to rotate, enabling the second rod 5 to push the test plate 7 and push the test plate 7 into the testing device 6.

[0049] In one embodiment, the first rod 4 and the second rod 5 are detachably or rotatably connected.

[0050] Specifically, such as Figure 5 As shown, the first rod 4 and the second rod 5 are detachably connected. Furthermore, the first rod 4 and the second rod 5 are connected by a threaded fastening method. When the size of the test plate 7 changes, the angle of the second rod 5 can be adjusted to push test plates 7 of different sizes into the test device 6.

[0051] like Figure 8 As shown, the first rod 4 and the second rod 5 are rotatably connected. When it is necessary to limit the test plate 7 through the first rod 4, the first rod 4 and the second rod 5 are rotated so that the first rod 4 and the second rod 5 can retract, thereby limiting the test plate 7 and preventing the test plate 7 from being pushed out.

[0052] Furthermore, the first rod 4 and the second rod 5 are fixed by welding, and the first rod 4 and the second rod 5 will form an angle after welding. When the first rod 4 is pushed, the second rod 5 fixed to it will also move and push the test plate.

[0053] In one embodiment, when the first rod 4 and the second rod 5 are detachably connected, the first rod 4 is provided with a fixing structure 402, and the second rod 5 is provided with a fixing hole; the fixing structure 402 includes at least one fixing member 403 and a plurality of through holes 404, the through holes 404 being arranged on the first rod 4; the fixing member 403 passes through the through holes 404 and is threadedly connected to the fixing hole.

[0054] Specifically, the first rod 4 is provided with a fixing structure 402, which includes a fixing member 403 and several through holes 404. In one specific embodiment, the fixing member 403 is a screw, and the fixing holes are threaded holes. During installation, after aligning the fixing holes of the second rod 5 with the through holes 404 of the first rod 4, the fixing member 403 is inserted through the through holes 404 and rotated into the fixing holes. When it is necessary to replace the second rod 5, the fixing member 403 is turned out to allow the second rod 5 to be disassembled. The first rod 4 and the second rod 5 are fixed by threads, and the angle of the second rod 5 can be adjusted according to the size of the test plate 7, thereby pushing test plates 7 of different sizes into the testing device 6.

[0055] Furthermore, such as Figure 4 As shown, through holes 404 are arranged on the first rod 4, allowing the second rod 5 to be installed in the corresponding through holes 404 according to actual needs. This makes the adjustment between the first rod 4 and the second rod 5 more flexible.

[0056] In one embodiment, the first rod 4 and the second rod 5 are rotatably connected, and a telescopic part 405 is provided between the first rod 4 and the second rod 5. The telescopic part 405 is movably connected to the first rod 4 and the second rod 5 respectively, and the second rod 5 is movably connected to the first rod 4.

[0057] like Figure 8 and Figure 9 As shown, specifically, a telescopic portion 405 is provided between the first rod 4 and the second rod 5. In a specific embodiment, as... Figure 8 As shown, two telescopic parts 405 are provided between the first rod 4 and the second rod 5. Figure 10 As shown, one end of the telescopic part 405 is movably connected to the first rod 4, and the other end is movably connected to the second rod 5. The first rod 4 and the second rod 5 are also movably connected.

[0058] More specifically, such as Figure 14 As shown, the first rod 4 has a cylinder 412, and the second rod 5 has a circular hole corresponding to the cylinder 412. The cylinder 412 is installed by fitting it into the circular hole, so that the first rod 4 and the second rod 5 can be rotatably connected. When the first rod 4 is rotated, the second rod 5 will rotate around the first rod 4 under the action of the telescopic rod, thereby contracting and opening.

[0059] In one embodiment, the telescopic part 405 includes a first telescopic rod 406 and a second telescopic rod 407. One end of the first telescopic rod 406 is rotatably connected to the first rod body 4, and the other end is rotatably connected to one end of the second telescopic rod 407. The other end of the second telescopic rod 407 is slidably connected to the second rod body 5.

[0060] like Figure 9 As shown, specifically, the telescopic part 405 includes a first telescopic rod 406 and a second telescopic rod 407. One end of the first telescopic rod 406 is rotatably connected to the first rod body 4, and the other end is rotatably connected to the second telescopic rod 407. One end of the second telescopic rod 407 is rotatably connected to the first telescopic rod 406, and the other end is slidably connected to the second rod body 5. A hinge structure is formed between the first telescopic rod 406 and the second telescopic rod 407 for extending and retracting the second rod body 5.

[0061] It is worth mentioning that the second telescopic rod 407 and the second rod body 5 can be connected by either a sliding connection or a rotational connection. Similarly, the first rod body 4 and the first telescopic rod 406 can be connected by either a rotational connection or a sliding connection.

[0062] In one embodiment, the first rod body 4 is provided with a first rotating hole 408, one end of the first telescopic rod 406 is provided with a first rotating column 409, and the other end is provided with a second rotating hole 410; the first rotating column 409 is movably disposed in the first rotating hole 408; one end of the second telescopic rod 407 is provided with a second rotating column 411, and the second rotating column 411 is movably disposed in the second rotating hole 410; the second rod body 5 is provided with a sliding groove 502, and the other end of the second telescopic rod 407 is located in the sliding groove 502 and is slidably connected to the sliding groove 502.

[0063] Specifically, such as Figure 9 As shown, the first rod body 4 is provided with a first rotating hole 408. (As indicated...) Figure 10 As shown, the first telescopic rod 406 is provided with a first rotating post 409. In a specific embodiment, the first rotating hole 408 is circular, and the first rotating post 409 corresponds to the first rotating hole 408 and is cylindrical. During assembly, the first rotating post 409 is installed in the first rotating hole 408, allowing the first telescopic rod 406 to rotate around the first rod body 4. The other end of the first telescopic rod 406 is provided with a second rotating hole 410, and the second telescopic rod 407 is provided with a second movable post corresponding to the second rotating hole 410. More specifically, the second rotating hole 410 is circular, and the second movable post corresponds to the second rotating hole 410 and is cylindrical. The second rotating post 411 is installed in the second rotating hole 410, allowing the second telescopic rod 407 to be rotatably connected to the first telescopic rod 406. The other end of the second telescopic rod 407 is located in the slide groove 502 and is slidably connected to the slide groove 502.

[0064] More specifically, such as Figure 11 The figure shows a cross-sectional view of the second telescopic rod 407 located in the slide groove 502. The other end of the second telescopic rod 407 can be T-shaped as shown in the figure, and can be engaged in the slide groove 502, slide in the slide groove 502, and will not fall off.

[0065] In one embodiment, when the first rod 4 rotates toward the placement area 2, the first rotating column 409 rotates in the first rotating hole 408, the second rotating column 411 rotates in the second rotating hole 410, and drives the second telescopic rod 407 to slide in the slide groove 502.

[0066] Specifically, such as Figure 12 As shown, the first rod 4 is rotated toward the placement area 2. During this process, the first rotating column 409 rotates in the first rotating hole 408, and the second rotating column 411 rotates in the second rotating hole 410, which in turn drives the second telescopic rod 407 to slide in the slide groove 502, thereby moving the second rod 5 toward the placement area 2 and pushing the test plate 7.

[0067] like Figure 13As shown, when it is necessary to limit the test plate 7, the second rod 5 needs to be retracted. By pushing the second rod 5, the first telescopic rod 406 and the second telescopic rod 407 rotate, and at the same time the second rod 5 rotates around the first rod 4 until the second rod 5 is retracted.

[0068] In one embodiment, the vehicle body 1 has corresponding sliding structures 101 on both sides, and each pair of sliding structures 101 constitutes a placement area 2; and the length of the sliding structure 101 is greater than the length of the test plate 7.

[0069] Specifically, such as Figure 2 As shown, the vehicle body 1 has corresponding sliding structures 101 on both sides, and the test plate 7 can slide within the sliding structure 101 to be pushed into the test device 6. The length of the sliding structure 101 is greater than the length of the test plate 7, allowing the test plate 7 to have room to move within the placement area 2. Each pair of sliding structures 101 constitutes a placement area 2, and the test plate 7 is placed within each placement area 2.

[0070] More specifically, the sliding structure 101 is a groove structure provided on the vehicle body 1, with the groove openings of the groove structure corresponding to each other. This allows the test plate 7 to be placed on the vehicle body 1 and to be pushed out of the vehicle body 1.

[0071] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the method embodiments are basically similar to the structural embodiments, so they are described more simply; relevant parts can be referred to the descriptions of the structural embodiments.
