Description

Technical Field

[0001] This invention belongs to the field of memory chip testing technology, specifically a chip placement and alignment device for memory chip testing. Background Technology

[0002] Memory chips are the specific application of the concept of embedded system-on-a-chip (SoC) in the storage industry. Therefore, both SoCs and memory chips achieve multifunctionality and high performance, as well as support for various protocols, hardware, and applications, by embedding software within a single chip.

[0003] After these chips are manufactured, they need to be tested before they can be put into use. When testing the chips, they need to be positioned in the testing device before testing. However, most of the time, the chips are placed manually. This is not only time-consuming and labor-intensive, but also prone to deviations when placing the chips manually, which may cause the chips to be out of alignment with the center of the testing device, thus affecting the data of subsequent tests. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a chip placement and alignment device for memory chip testing, which has the advantages of aligning chips and ensuring testing accuracy. This invention solves the problem of inaccurate chip alignment with the testing device during chip testing, ensuring that the chip corresponds correctly to the testing device, while simultaneously improving testing accuracy and increasing work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chip placement and alignment device for memory chip testing, comprising a worktable, a fixed base fixedly disposed inside the worktable, and a power assembly disposed on the bottom surface of the fixed base, the power assembly including a motor fixedly disposed on the bottom surface of the fixed base.

[0006] A main gear is fixedly installed at the end of the motor's main shaft. Multiple secondary gears are connected to the outer internal teeth of the main gear. A threaded shaft is fixedly installed inside the secondary gear. A sliding seat is threadedly connected to one side of the threaded shaft, and the sliding seat is slidably connected to the worktable. A buffer assembly is provided on the top surface of the sliding seat, and the outer side of the buffer assembly is in contact with the outer side of the storage chip to be tested.

[0007] Preferably, the buffer assembly includes a fixed frame fixedly disposed on the top surface of the sliding seat.

[0008] Multiple fixed shafts are fixedly installed on the inner side of the fixed frame, a swing frame is rotatably installed on the outer side of the fixed shafts, and a roller is rotatably installed on the inner side of the swing frame.

[0009] Preferably, a plurality of springs are fixedly provided on the inner side of the swing frame, and the other side of the springs is fixedly connected to another swing frame.

[0010] Preferably, a fixing frame is fixedly provided on the top surface of the workbench, and a test component is provided on the top surface of the fixing frame.

[0011] Preferably, a support seat is rotatably connected to the other end of the threaded shaft, and the support seat is fixedly connected to the worktable.

[0012] Preferably, a plurality of fixed platforms are fixedly arranged on the outer side of the workbench, and a threaded rod is threadedly connected to the inside of the fixed platform. A handwheel is fixedly arranged on the top surface of the threaded rod, and a disc is fixedly arranged on the bottom surface of the threaded rod.

[0013] Preferably, a rotating disk is rotatably mounted on the center of the top surface of the workbench, and multiple casters are fixedly mounted on the bottom of the workbench.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses a motor to drive the main gear to rotate, the main gear drives multiple auxiliary gears, and the auxiliary gears drive the outer threaded shaft to rotate. The threaded shaft engages with the sliding seat, thereby driving the buffer assembly to move. The buffer assembly simultaneously pushes the four sides of the chip to align it with the testing device, thereby reducing manpower consumption and ensuring the positioning of the chip, and promoting the smooth progress of the test.

[0016] 2. This utility model uses rollers to push the chip to help it align with the test component, and then continues to push the chip. At this time, the swing bracket on the outside of the fixed shaft begins to open outward, thereby avoiding excessive force that could damage the chip and thus protecting the chip from damage.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 5 As shown, this utility model provides a chip placement and alignment device for memory chip testing, including a worktable 1, a fixing base 2 fixedly disposed inside the worktable 1, and a power assembly 3 disposed on the bottom surface of the fixing base 2. The power assembly 3 includes a motor 301 fixedly disposed on the bottom surface of the fixing base 2.

[0028] A main gear 302 is fixedly installed at the end of the main shaft of motor 301. Multiple auxiliary gears 303 are connected to the outer internal teeth of the main gear 302. A threaded shaft 304 is fixedly installed inside the auxiliary gears 303. A sliding seat 305 is threadedly connected to one side of the threaded shaft 304, and the sliding seat 305 is slidably connected to the worktable 1. A buffer assembly 4 is provided on the top surface of the sliding seat 305. The outer side of the buffer assembly 4 is in contact with the outer side of the storage chip to be tested. The motor 301 drives the main gear 302 to rotate, the main gear 302 drives the multiple auxiliary gears 303, and the auxiliary gears 303 drive the outer threaded shaft 304 to rotate. The threaded shaft 304 moves the buffer assembly 4 by meshing with the sliding seat 305. The buffer assembly 4 pushes the four sides of the chip to align it with the testing device, thereby reducing manpower consumption and ensuring chip positioning, and promoting the smooth progress of testing.

[0029] Specifically, the buffer assembly 4 includes a fixing frame 401 fixedly disposed on the top surface of the sliding seat 305.

[0030] Multiple fixed shafts 402 are fixedly installed on the inner side of the fixed frame 401. A swing frame 403 is rotatably installed on the outer side of the fixed shaft 402. A roller 404 is rotatably installed on the inner side of the swing frame 403. The roller 404 pushes the chip to help it be positioned and aligned with the testing device. Then, the chip is pushed. At this time, the swing frame 403 on the outer side of the fixed shaft 402 begins to open outward, thereby avoiding excessive force that could damage the chip and thus protecting the chip from damage.

[0031] Furthermore, multiple springs 405 are fixedly installed on the inner side of the swing frame 403, and the other side of the spring 405 is fixedly connected to another swing frame 403. The spring 405 is used to help the swing frame 403 reset.

[0032] Furthermore, a mounting bracket 6 is fixedly installed on the top surface of the workbench 1, and a testing component 7 is installed on the top surface of the mounting bracket 6. The testing component 7 is used to test the chip, thereby ensuring the quality of the chip.

[0033] It is worth noting that the other end of the threaded shaft 304 is rotatably connected to a support seat 5, and the support seat 5 is fixedly connected to the worktable 1. The support seat 5 is used to support one end of the threaded shaft 304, and the other end is supported by the worktable 1.

[0034] It is worth noting that multiple fixed platforms 9 are fixedly installed on the outside of the workbench 1. The fixed platform 9 is internally threaded with a threaded rod 11. A handwheel 10 is fixedly installed on the top surface of the threaded rod 11, and a disc 12 is fixedly installed on the bottom surface of the threaded rod 11. The disc 12 is moved by the handwheel 10, thereby lifting the entire device to ensure the stability of the device.

[0035] It is worth mentioning that a rotating disk 13 is rotatably installed in the center of the top surface of the workbench 1, and multiple moving wheels 8 are fixedly installed at the bottom of the workbench 1. The rotating disk 13 is used to place the chip, which can avoid the chip from rubbing against the workbench 1 and affecting alignment. The moving wheels 8 are used to move and place the device.

[0036] Among them, motor 301 and test component 7 are existing technologies and will not be described in detail; at the same time, this utility model also includes power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0037] Working principle:

[0038] When using the chip placement and alignment device for memory chip testing, firstly, the chip is placed on the rotating disk 13 at the top of the workbench 1. Then, the motor 301 in the power assembly 3 is turned on. The motor 301 is mounted via the mounting base 2. The motor 301 drives the main gear 302 to rotate, which in turn drives multiple secondary gears 303. The secondary gears 303 drive the outer threaded shaft 304 to rotate. The threaded shaft 304, through engagement with the sliding seat 305, drives the buffer assembly 4 to move. When the buffer assembly 4 moves near the chip, the roller 404 pushes the chip to help it align with the test assembly 7 on the top surface of the mounting bracket 6. Then, the chip is pushed further, and at this time, the swing bracket 403 outside the mounting shaft 402 begins to move outward. The opening mechanism prevents excessive force from damaging the chip. When the fixed frame 401 moves outward, the spring 405 helps it return to its original position. The support base 5 supports multiple threaded shafts 304, and the moving wheel 8 moves the entire device, making it convenient for staff to initially position the device. After the device is positioned, the handwheel 10 is turned, which drives the threaded rod 11 to engage with the fixed platform 9, thereby moving the disc 12 downward. The disc 12 lifts the device, ensuring its stability and safety. This invention solves the problem of not being able to accurately align the chip with the testing device when testing chips, ensuring that the chip corresponds to the testing device, while also improving testing accuracy and work efficiency.
