Abstract
Description
Technical Field
[0001] This utility model relates to a detection and adjustment device, specifically a high-precision chip current detection and adjustment device, belonging to the field of chip debugging technology. Background Technology
[0002] Chip debugging is a crucial step in the chip design and manufacturing process. It refers to the process of identifying and resolving problems within the chip after its initial design and manufacturing, through a series of tests and verifications, to ensure the chip functions and performs as expected. The debugging process typically includes steps such as executing verification test cases, identifying problems, determining the nature and location of errors, and correcting errors.
[0003] Operating current is a direct reflection of chip power consumption. By detecting the operating current, the chip's power consumption level can be assessed, which is one of the important indicators for measuring chip performance. Power consumption not only affects the chip's operating efficiency but also directly relates to the device's battery life and overall energy consumption. Therefore, during chip debugging, it is necessary to detect and adjust its operating current.
[0004] A known Chinese patent (publication number: CN206193219U) discloses a convenient current sensor chip detection device, which uses a push rod motor to drive a push rod to move, and the push rod drives a detection rod to contact the chip for detection, thereby achieving the effect of detecting whether the chip is qualified or not.
[0005] It uses a push rod motor as a drive to make the detection rod contact the chip. However, the contact part with the chip is not equipped with a buffer mechanism. Therefore, when the pressure of the detection rod is too high, it will cause damage to the chip. To address this, a high-precision chip current detection and adjustment device is proposed. Utility Model Content
[0006] In view of this, the present invention provides a high-precision chip current detection and regulation device to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.
[0007] The technical solution of this utility model embodiment is implemented as follows: a high-precision chip current detection and adjustment device, including a detection component, the detection component including a pressure plate, a spring, two electric push rods, four guide rods, two test connection lines, a current sensor, a needle plate, an adjustment terminal, two side plates, a lifting seat and four limit rods;
[0008] The needle plate is fixedly connected to the lower surface of the pressure plate. The bottom ends of the two test connection lines are symmetrically fixedly connected to the upper surface of the needle plate. The two current sensors are symmetrically installed on the upper surface of the pressure plate. The bottom ends of the four limit rods are symmetrically fixedly connected to the upper surfaces of the two lifting seats. The spring is sleeved on the outer side wall of the limit rod. The bottom ends of the four guide rods are symmetrically fixedly connected to the upper surfaces of the two lifting seats. The two electric push rods are symmetrically installed on the upper surfaces of the two side plates. The adjustment terminal is installed on the side of one of the side plates away from the lifting seat.
[0009] More preferably, one end of the spring is fixedly connected to the top end of the limiting rod, and the other end of the spring abuts against the upper surface of the pressure plate.
[0010] More preferably, the bottom end of the electric push rod is fixedly connected to the upper surface of the lifting seat, and the pressure plate is slidably connected to the outer side wall of the four limiting rods.
[0011] More preferably, the guide rod is slidably connected to the inside of the side plate.
[0012] More preferably, the test connection line is located inside the current sensor.

[0014] The sliding base is slidably connected to the upper surface of the base, and the chip placement slot is formed on the upper surface of the sliding base.
[0015] More preferably, the lower surfaces of the two side plates are symmetrically fixed to the upper surface of the base, and the position of the chip placement slot corresponds to the position of the pin plate.
[0016] More preferably, a handle is fixedly connected to the front surface of the sliding seat.
[0017] This utility model embodiment, by adopting the above technical solution, has the following advantages: The utility model uses an electric push rod to move the lifting seat downwards, which in turn moves the pressure plate downwards, causing the needle plate to move downwards. The contact needles of the needle plate contact the chip's contacts, thus enabling the chip to conduct through the test connection line. A spring pushes the pressure plate, keeping the needle plate in contact with the chip's contacts. During testing, a current sensor can detect the chip's operating current in real time, and the current can be adjusted by a regulating terminal. Compared to existing technologies, this utility model, by setting a spring, prevents the chip from being damaged when the pressure is too high during chip pressing.

Detailed Implementation
[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.
[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0027] like Figure 1-4 As shown, this utility model embodiment provides a high-precision chip current detection and adjustment device, including a detection component 101. The detection component 101 includes a pressure plate 11, a spring 12, two electric push rods 13, four guide rods 14, two test connection lines 15, a current sensor 16, a needle plate 17, an adjustment terminal 18, two side plates 19, a lifting seat 20, and four limit rods 21.
[0028] The needle plate 17 is fixedly connected to the lower surface of the pressure plate 11. The bottom ends of the two test connection lines 15 are symmetrically fixedly connected to the upper surface of the needle plate 17. The two current sensors 16 are symmetrically installed on the upper surface of the pressure plate 11. The bottom ends of the four limit rods 21 are symmetrically fixedly connected to the upper surface of the two lifting seats 20. The spring 12 is sleeved on the outer side wall of the limit rod 21. The bottom ends of the four guide rods 14 are symmetrically fixedly connected to the upper surface of the two lifting seats 20. The two electric push rods 13 are symmetrically installed on the upper surface of the two side plates 19. The adjustment terminal 18 is installed on the side of one side plate 19 away from the lifting seat 20.
[0029] In one embodiment, one end of the spring 12 is fixedly connected to the top end of the limiting rod 21, and the other end of the spring 12 presses against the upper surface of the pressure plate 11. The pressure plate 11 is pushed by the spring 12, and the pressure plate 11 drives the needle plate 17, which can keep the needle plate 17 in contact with the chip. When the pressure is too high, the spring 12 is compressed, which can prevent the chip from being crushed. After the needle plate 17 contacts the chip, it conducts electricity and the needle plate 17 conducts electricity with the test connection line 15.
[0030] In one embodiment, the bottom end of the electric push rod 13 is fixedly connected to the upper surface of the lifting seat 20, and the pressure plate 11 is slidably connected to the outer side wall of the four limiting rods 21. The position of the pressure plate 11 can be limited by the limiting rods 21, and the position of the pressure plate 11 will not shift during the test.
[0031] In one embodiment, the guide rod 14 is slidably connected to the inside of the side plate 19. The position of the lifting seat 20 can be limited by the guide rod 14 so that the lifting seat 20 can be raised and lowered vertically.
[0032] In one embodiment, the test connection line 15 is located inside the current sensor 16. The signal terminal of the current sensor 16 is connected to the signal terminal of the regulating terminal 18. The current sensor 16 is a Hall sensor, model AHKC-EKAA. The regulating terminal 18 is equipped with a display screen to display current data. The regulating terminal 18 is equipped with a current regulating controller, model INA260AIPWR, which can then regulate the current.
[0033] In one embodiment, a support assembly 301 is mounted on the lower surface of the side plate 19. The support assembly 301 includes a base 31, a sliding seat 32, and a chip placement slot 33.
[0034] The sliding base 32 is slidably connected to the upper surface of the base 31, and the chip placement slot 33 is opened on the upper surface of the sliding base 32. The sliding base 32 facilitates the placement and removal of the chip.
[0035] In one embodiment, the lower surfaces of the two side plates 19 are symmetrically fixed to the upper surface of the base 31, the position of the chip placement slot 33 corresponds to the position of the needle plate 17, and the front surface of the sliding seat 32 is fixedly connected to the handle 34. The position of the detection component 101 can be limited by the side plates 19, thereby enhancing the stability of the overall structure.
[0036] In operation, this invention works as follows: by pulling out the sliding seat 32 with the handle 34, the chip to be tested is placed in the chip placement slot 33. Then, the sliding seat 32 is pushed to move above the base 31. The lifting seat 20 is pushed downward by the electric push rod 13. The lifting seat 20 drives the pressure plate 11, and the pressure plate 11 drives the needle plate 17 downward, so that the contact needle of the needle plate 17 contacts the chip's contact point, thereby enabling the chip to conduct through the test connection line 15. The pressure plate 11 is pushed by the spring 12, which keeps the needle plate 17 in contact with the chip's contact point. At this time, chip testing can be performed. During the testing process, the current sensor 16 can detect the chip's operating current in real time, and then the current magnitude can be adjusted by the adjustment terminal 18.
[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
