Description

Technical Field

[0001] The present invention relates to the technical field of chip detection, and in particular to chip detection equipment for electronic information engineering. Background Art

[0002] A chip is a general term for semiconductor components, classified as integrated circuits, and composed of a large number of transistors. Different chips have varying levels of integration, ranging from hundreds of millions to tens or hundreds of transistors. Transistors have two states: on and off, represented by 1 and 0. Multiple transistors generate multiple 1 and 0 signals, which are programmed to specific functions (i.e., instructions and data) to represent or process letters, numbers, colors, and graphics. When the chip is powered on, it first generates a startup instruction to activate the chip, and then continuously accepts new instructions and data to complete its function.

[0003] With the continuous advancement of technology, integrated circuit chips, as core components of electronic devices, have become increasingly important for their performance and quality, crucial to the stability and reliability of the entire electronic product. Therefore, rigorous testing of integrated circuit chips is particularly important. Chip testing equipment was developed precisely to meet this demand. Chip testing requires a probe to be brought close to the chip. However, existing chip testing equipment suffers from poor coordination and interoperability between the chip loading assembly and the probe's proximity testing component, resulting in a low degree of automation.

[0004] For example, the Chinese invention patent with patent publication number CN113009320B discloses an optical chip detection seat that can be used for high-frequency testing. The device uses motor 2 to drive the rotation of the turntable to perform work station conversion, and then uses motor 1 to drive the detection needle through the upper detection seat to approach the chip at the detection position for chip detection. In this detection method, it is difficult to achieve the linkage and coordination between motor 1 and motor 2 during the working process, and the degree of automation is low.

[0026] like Figures 1 to 6 As shown, a chip detection device for electronic information engineering includes a base plate 1, a controller, and a detection probe 2 electrically connected to the controller. A conveyor is provided on the base plate 1. The conveyor includes two oppositely arranged side plates 3. Two rollers 4 are rotatably connected between the two side plates 3. The two rollers 4 are distributed at both ends of the two side plates 3. A conveyor belt 5 is connected to the two rollers 4 in a driving manner.

[0027] A first support member 6 is provided at the front end of one of the side panels 3, and a driving wheel 7 is rotatably connected to the first support member 6. A driving pin 8 is eccentrically provided on the driving wheel 7. A driven wheel 9 is coaxially provided on the roller 4 at the front end, and a plurality of driving grooves 10 adapted to the driving pin are provided in a ring array on the edge of the driven wheel 9. A first cam 11 is coaxially provided on the driving wheel 7. A second support member 12 is provided on the other side panel 3, and a lifting rod 13 is vertically slidably connected to the second support member 12. An "L"-shaped connecting rod 14 is provided on the lifting rod 13, and the detection needle 2 is provided at the lower end of the "L"-shaped connecting rod 14. A driving device for driving the first cam 11 and the driving wheel 7 to rotate synchronously is provided on the base plate 1.

[0028] During specific use, the chip to be tested is evenly placed on the upper conveyor belt 5 from the rear end of the conveyor by manual or mechanical means, and the driving device drives the first cam 11 and the driving wheel 7 to rotate synchronously. One rotation of the driving wheel 7 will drive the driving pin 8 to rotate one circle. The driving pin 8 drives the driven wheel 9 to rotate a specific angle through the driving slot 10, and the driven wheel 9 drives the roller 4 coaxially arranged therewith to rotate synchronously. The two rollers 4 have a tension effect on the conveyor belt 5. When the roller 4 rotates, the conveyor belt 5 will be driven to rotate synchronously through the friction force, so that the conveyor belt 5 moves a specific distance, so that the chip to be tested is intermittently moved in sequence to the point directly below the detection position detection needle 2. The first cam 11 rotates synchronously one circle to drive the lifting rod 13 to lift once. The lifting rod 13 drives the detection needle 2 to lift once through the "L"-shaped connecting rod 14 to approach the chip to be tested, and detect the chip. The driving device continues to work, so that the work station conversion and the lifting and lowering detection of the detection needle 2 are carried out continuously.

[0029] In order to achieve the purpose of improving detection accuracy, preferably, a first elastic member 15 is provided between the lifting rod 13 and the second support member 12. The lower end of the lifting rod 13 is in close contact with the first cam 11 under the action of the elastic potential energy of the first elastic member 15. The first elastic member 15 is preferably a spring. During detection, the detection needle 2 is in close contact with the chip under the action of the elastic potential energy of the spring, avoiding poor contact and improving detection accuracy.

The number of the locking grooves 17 is the same as the number of the driving grooves 10 and is evenly spaced. Each time the driving wheel 7 drives the driven wheel 9 to rotate once, the locking arc 16 is embedded in the locking groove 17 once to prevent the driven wheel 9 from rotating by inertia. The intermittent rotation of the driven wheel 9 drives the conveyor to rotate intermittently.

[0031] In order to achieve the purpose of improving detection accuracy, preferably, a plurality of detection grooves 18 are evenly arranged on the conveying surface of the conveyor belt 5 to facilitate the positioning and placement of the chip, and the adjacent chips are evenly spaced, so that when the chip to be detected moves to the detection position, it is just below the detection needle 2, thereby improving the detection accuracy and detection efficiency.

[0032] In order to achieve the purpose of improving the detection accuracy, preferably, the internal sliding connection of the detection groove 18 is connected to the limit plate 19, and the limit plate 19 is provided with a guide rod 20 that is slidably connected to the side wall of the detection groove 18, and a tension spring 21 is provided between the limit plate 19 and the inner wall of the detection groove 18, and a trapezoidal guide block 22 is provided on the inner wall of the side plate 3 on the same side as the guide rod 20. When the chip to be detected moves to the detection position, under the extrusion action of the rear end inclined surface of the trapezoidal guide block 22, the limit plate 19 moves toward the side plate 3 on the other side, clamping the chip and fixing it at the same time, stretching the tension spring 21. After the detection is completed, when the chip is moved out of the detection position, the guide rod 20 gradually disengages from the front end inclined surface of the trapezoidal guide block 22, and the limit plate 19 is reset under the tension of the tension spring 21, releasing the chip, which has the effect of automatically fixing the chip during detection and automatically releasing the chip after detection, avoiding chip dislocation and improving detection accuracy.

[0033] In order to achieve the purpose of automatically sorting chips, preferably, a collection box 23 is slidably connected to the bottom plate 1, and a partition 24 is provided inside the collection box 23. The partition 24 divides the collection box 23 into a good product slot and a waste slot.

The telescopic device is electrically connected to the controller, and a photoelectric sensor 25 electrically connected to the controller is provided at the front end of the conveyor. The photoelectric sensor 25 is a through-beam sensor or a mirror reflection sensor, and the telescopic device is an electric push rod or a cylinder. Here, the front end of the collection box 23 is taken as the good product slot and the rear end of the collection box 23 is taken as the waste slot as an example. In the initial state, the good product slot is directly below the front end of the conveyor. The chips after inspection continue to move toward the front end with the conveyor. When the photoelectric sensor 25 detects that a defective product has passed, the telescopic end of the telescopic device extends, and the defective product falls into the waste slot. When the photoelectric sensor 25 detects that a good product has passed, the telescopic end of the telescopic device contracts, and the good product falls into the good product slot.

During operation, the second cam 32 intermittently squeezes the piston rod 31, and the piston rod 31 drives the piston 29 to slide inside the piston cylinder 26. While squeezing the gap, the piston 29 is reset under the elastic potential energy of the second elastic member 30, so that the piston 29 performs piston motion inside the piston cylinder 26, extracts the air purified by the filter and blows it to the chip at the detection position to clean the chip and prevent dust from affecting the detection accuracy.

[0035] In order to achieve the purpose of chip detection, preferably, the driving device includes a driving part 33 arranged on the base plate 1, and the output end of the driving part 33 is provided with a driving pulley 34, and the driving wheel 7 is coaxially provided with a driven pulley 35, and a belt 36 is connected between the driving pulley 34 and the driven pulley 35.
