Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, and in particular to a chip multi-faceted testing device. Background Technology
[0002] The main purpose of visual inspection of chips is to ensure that the surface (including pins) is free of defects, thus ensuring product quality and reliability. The specific reasons are as follows: (1) To prevent surface defects from causing performance degradation. Scratches, cracks, particle contamination and other defects on the chip surface may directly affect the circuit conduction or signal transmission quality, leading to functional abnormalities. For example, surface defects of RF chips may cause RF signal attenuation or interference. (2) To ensure packaging reliability. After packaging, the chip needs to be visually inspected to confirm that the pins are not deformed and the packaging material is free of defects, so as to avoid detachment or short circuit due to packaging process problems during long-term use. (3) To meet the market requirements for precision manufacturing. Modern electronic devices have extremely high requirements for chip precision. Micron-level or even submicron-level surface defects may cause functional failures. Visual inspection can meet the needs of high-precision application scenarios such as consumer electronics and automotive electronics.
[0003] In existing technologies, when inspecting the appearance of chips (generally through sampling), the chip is placed under a camera. The image captured by the camera is magnified and displayed on a screen, and technicians observe the image on the screen to detect any defects in the chip. This method requires manual flipping of the chip when inspecting multiple sides, especially when inspecting the four side leads. When the chip is placed in different orientations, it requires repeated clamping to fix it in place (changing the orientation of the chip side under the camera), which is inconvenient and reduces inspection efficiency. Therefore, it is essential to provide a testing device that facilitates chip inspection and improves efficiency. Utility Model Content
[0004] In order to overcome the shortcomings of existing chip testing mechanisms due to structural limitations, as described in the background art, this utility model provides a chip multi-faceted testing device that, with the joint action of related mechanisms, can easily fix and flip the chip, and can adjust the distance between the chip testing surface and the lower end of the camera to a suitable testing distance as needed, thereby bringing convenience to the testing personnel and improving the testing efficiency.
[0005] The technical solution adopted by this utility model to solve its technical problem is: A chip multi-faceted inspection device includes a touch module, a body, a camera, and a display screen. It also includes a lifting device, a clamping and rotating device, and a control circuit. The lifting device includes an electric push rod, linear bearings, and a support plate. Multiple linear bearings have their bearing seats fixedly mounted around the lower end of the body, and their bearing rods fixedly mounted around the lower end of the support plate. The lower end of the electric push rod's cylinder is fixedly mounted inside the body, and the upper end of its movable column is fixedly mounted on the lower end of the support plate. The body has an opening on each of its two upper sides. The clamping and rotating device includes a motor reduction mechanism, bearing seats, an electric push rod, a support base, and a clamping plate. There are at least two electric push rods, clamping plates, and support bases. The lower ends of the two support bases are fixedly mounted on the upper sides of the support plate, and the upper parts of the two support bases are movably located on the upper sides of the body. Outside the upper part of the opening, the lower ends of the cylinders of the two electric push rods A are respectively horizontally fixedly installed on two support seats; the housing of the motor reduction mechanism is fixedly installed on the side end of one of the electric push rods A, the seat of the bearing seat is fixedly installed on the side end of the other electric push rod A, and a shaft is fixedly installed inside the inner ring of the bearing seat; the middle parts of the outer ends of the two clamping plates are respectively fixedly installed on the side end of the rotating shaft of the motor reduction mechanism and the side end of the shaft; a support frame is fixedly installed on the upper end of the machine body, and the camera is fixedly installed on the lower side of the upper end of the support frame; the display screen is fixedly installed on the upper end of the support frame, the touch module and the control circuit are installed in the component box, the component box is fixedly installed on the front side of the machine body, the signal output terminal of the touch module and the signal input terminal of the control circuit are electrically connected, and the multi-channel power output terminal of the control circuit is electrically connected to the power input terminals of the electric push rod, the electric push rod A, and the motor reduction mechanism respectively.
[0006] Furthermore, the inner diameter of the openings on both sides of the upper end of the body is larger than the outer diameter of the support base.
[0007] Furthermore, when the movable column of the electric push rod is at the lower dead center, the height of the lower ends of the two clamping plates is greater than the height of the upper end of the machine body. When the movable column of the electric push rod is at the upper dead center, the distance between the lower ends of the two clamping plates and the outer edge of the upper end of the machine body is greater than the radius of the chip being detected.
[0008] Furthermore, the two clamping plates are laterally aligned on the same plane, and anti-slip pads are fixedly installed on the inner sides of the two clamping plates respectively.
[0009] Furthermore, the control circuit includes multiple relays, with the positive control power input terminals of the multiple relays connected together, and the negative power input terminals of the multiple relays connected together with the negative control power input terminal.
[0010] Compared with existing technologies, the advantages of this invention are as follows: When applied, the chip can be easily fixed via touch control, two sets of electric push rods A, and a clamping plate.

The electric push rods, in conjunction with the linear bearing, can adjust the distance between the chip detection surface and the lower end of the camera to a suitable detection distance, thus providing convenience for testing personnel and improving testing efficiency. In summary, this invention has good application prospects. Attached Figure Description

[0014] Figure 1 , 2As shown, a chip multi-faceted inspection device includes a power module W1, touch modules W2, W3, W4, W5, W6, and W7, a body 1, a camera 2, and a display screen 3; it also includes a lifting device, a clamping and rotating device, and a control circuit 4; the lifting device includes an electric push rod M1, linear bearings 51, and a support plate 52. There are four linear bearings 51, with the lower ends of the bearing seats of the four linear bearings 51 fixedly installed around the lower end of the body 1, and the upper ends of the bearing rods of the four linear bearings 51 fixedly installed around the lower end of the support plate 52. The lower end of the cylinder of the electric push rod M1 is fixedly installed in the middle of the lower end of the body 1. The upper end of the movable column of the push rod M1 is fixedly installed in the middle of the lower end of the support plate 52; the upper middle of the machine body 1 has an opening 101 on each side; the clamping and rotating device includes a motor reduction mechanism M2, a bearing seat 61, an electric push rod AM3, a support seat 62, and a clamping plate 63. There are at least two electric push rods AM3, clamping plates 63, and support seats 62. The lower ends of the two support seats 62 are fixedly installed in the middle of the upper sides of the support plate 52, and the middle parts of the two support seats 62 are respectively movably located outside the upper part of the openings 101 on both sides of the upper end of the machine body. The lower ends of the cylinders of the two electric push rods AM3 are respectively horizontally fixedly installed on the two support plates 52. On the support 62, the movable columns of the two electric push rods AM3 are arranged in an inner face-to-face structure; the middle left side of the housing of the motor reduction mechanism M2 is fixedly installed on the right side of the left electric push rod AM3, the middle right side of the bearing seat 61 is fixedly installed on the left side of the right electric push rod AM3, a shaft 64 is fixedly installed on the left side of the inner ring of the bearing in the bearing seat 61, and the middle outer sides of the two clamping plates 63 are respectively fixedly installed on the right side of the rotating shaft of the motor reduction mechanism M2 and the left side of the shaft 64; a "Π"-shaped support frame 7 is fixedly installed on the upper end of the machine body (the middle of both sides of the support frame is from bottom to top). The structure is hollow, with a height of about 10 cm, allowing the support base to drive the electric push rod M3 to rise or fall along the hollow section. The upper end of the camera 2's housing is fixedly mounted on the lower middle part of the upper end of the support frame 7, with the lens of the camera 7 located on the lower side. The display screen 3 is fixedly mounted on the upper middle part of the support frame. The power module W1, touch modules W2, W3, W4, W5, W6, and W7, and control circuit 4 are mounted on the circuit board inside the component box 8. The component box 8 is fixedly mounted on the upper left front part of the body 1 (the touch pads of touch modules W2, W3, W4, W5, W6, and W7 are spaced apart at the front edge of the component box). Figure 1 , 2As shown, the inner diameter of the openings 101 on both sides of the upper end of the machine body is larger than the outer diameter of the support base 62. When the movable column of the electric push rod M1 is at the lower stop point, the height of the lower ends of the two clamping plates 63 is greater than the height of the upper end of the machine body 1. When the movable column of the electric push rod M1 is at the upper stop point, the distance between the lower ends of the two clamping plates 63 and the outer edge of the upper end of the machine body 1 is greater than the radius of the chip being tested. The two clamping plates 63 are laterally aligned on the same plane, and an anti-slip pad 631 is glued to the inner side of each of the two clamping plates 63 (to prevent the clamped chip from slipping). The control circuit includes six relays K1, K2, K3, K4, K5, and K6. The positive control power input terminals of the six relays K1, K2, K3, K4, K5, and K6 are connected, and the negative power input terminals and the negative control power input terminals of the six relays K1, K2, K3, K4, K5, and K6 are connected. The power input terminals 1 and 2 of display screen 3 and power module W1 are connected to the two poles of AC 220V power supply via wires. The power output terminals 3 and 4 of power module W1 are connected to the positive and negative power input terminals of relay K1 in the control circuit. The power input terminals 1 and 2 of touch modules W2, W3, W4, W5, W6, and W7, and the two power input terminals of camera 2 are connected via wires. Pin 3 of touch modules W2, W3, W4, W5, W6, and W7 is connected to the positive power input terminals of the six relays K1, K2, K3, K4, K5, and K6 via wires. The normally open contacts of relays K1 and K2 are connected to the positive and negative, and negative-positive power input terminals of electric push rod M1 via wires. Similarly, the normally open contacts of relays K3 and K4 are connected to the positive and negative, and negative-positive power input terminals of motor reduction mechanism M2 via wires. The normally open contacts of relays K5 and K6 are connected to the positive and negative, and negative-positive power input terminals of electric push rod AM3 via wires. The signal output terminal of camera 2 and the signal input terminal of display screen 3 are connected via a video cable.
[0015] Figure 1 , 2As shown, after the AC 220V power supply enters the power input terminal of the power module W1, the power module W1 outputs a stable DC 12V power supply through pins 3 and 4, which enters the power input terminals of the control circuit, the six touch modules, and the camera 2. After turning on the power switch of the display screen 3, the display screen 3 is powered on and displays the image signal (the corresponding image of the chip) input by the camera 2. Before testing this new type of chip, it is necessary to clamp the chip between two clamping plates 52 (place the corresponding side of the chip between the two clamping plates with one hand, and then touch the touch pad of the corresponding touch module with the other hand). Specifically, when the chip is clamped horizontally between the two clamping plates, the subsequent camera 2 can collect images of the top, bottom, front, and back ends of the chip. When the chip is clamped vertically between the two clamping plates, the subsequent camera 2 can collect images of the four sides of the chip. When the inspector touches the touch pad of the touch module W6, pin 3 of the touch module W6 outputs a high level, which enters the positive power input terminal of the relay K5. The relay K5 is energized and its control power input terminal and normally open contact terminal close. Subsequently, the positive and negative power input terminals of the two electric push rods AM3 are energized. The movable columns of the two electric push rods AM3 drive the two clamping plates 63 to move inward toward each other, reducing the distance between the two clamping plates 63, thus effectively clamping the chip. After the chip is clamped, the inspector removes their finger from the touch pad of the touch module W6, and pin 3 of the touch module W6 stops outputting a high level, allowing the subsequent testing process to begin. If the chip being tested is held vertically at a relatively low or high height, when the operator touches the touch pad of touch module W2 or W3, pin 3 of touch module W2 or W3 outputs a high level, which enters the positive power input terminal of relay K1 or K2. Relay K1 or K2 is energized and its control power input terminal and normally open contact terminal close. Consequently, the positive and negative or negative and positive power input terminals of electric push rod M1 are energized, and the movable column of electric push rod M1 drives support plate 52 and support base 62 to move upward or downward respectively (the linear bearing plays a guiding role). As a result, the distance between the chip and the lower end of the camera decreases or increases, so that the lower end lens of camera 2 can be appropriately spaced from the chip, achieving a good image acquisition effect. After the chip is in place, the operator removes their finger from the touch pad of touch module W2 or W3, and pin 3 of touch module W2 or W3 stops outputting a high level, and the subsequent testing process can begin.
[0016] Figure 1 , 2As shown, when testing a chip, the image captured by camera 2 is magnified and displayed on screen 3. Technicians can then detect whether the chip has any defects by observing the image on screen 3. During testing, when the chip needs to be rotated and flipped (so that the undetected side rotates from the bottom to the top and is in a horizontal state), when the tester touches the touch pad of the touch module W4 or W5, pin 3 of the touch module W4 or W5 outputs a high level, which enters the positive power input terminal of the relay K3 or K4. The relay K3 or K4 is energized and its control power input terminal and normally open contact terminal close. Then, the positive and negative or negative and positive power input terminals of the motor reduction mechanism M2 are energized, and the rotating shaft of the motor reduction mechanism M2 drives the clamping plate and the chip to rotate clockwise backward or counterclockwise forward (the left end of the chip is driven to rotate by the motor reduction mechanism through the left clamping plate, and the right end of the chip rotates along the inner ring of the bearing seat through the right clamping plate). After the chip rotates to the correct position, the tester's finger leaves the touch pad of the touch module W4 or W5, and pin 3 of the touch module W4 or W5 stops outputting a high level. The chip stops rotating, the detection surface is at the top, and the subsequent testing process can begin. After the test is completed, the main power switch is turned off. Then, when the tester touches the touch pad of the touch module W7, pin 3 of the touch module W7 outputs a high level, which enters the positive power input terminal of the relay K6. The relay K6 is energized and its control power input terminal and normally open contact terminal close. Subsequently, the negative and positive power input terminals of the two electric push rods AM3 are energized. The movable columns of the two electric push rods AM3 drive the two clamping plates 63 to move outward, and the distance between the two clamping plates 63 increases, thus releasing the clamped chip. The tester can then remove the tested chip by hand. After the chip is removed, the tester's finger leaves the touch pad of the touch module W7, and pin 3 of the touch module W7 stops outputting a high level, thus completing the entire test process.
[0017] Figure 1 , 2 As shown, through all the above technical solutions, this utility model can easily fix the chip by touch control, two sets of electric push rods A and clamping plates, etc. The motor reduction mechanism combined with bearing seats can flip the clamped new product. The electric push rods and linear bearings can adjust the distance between the chip detection surface and the lower end of the camera to a suitable detection distance as needed, thereby bringing convenience to the inspection personnel and improving the inspection efficiency accordingly. Figure 2In this system, power module W1 is a finished product of AC 220V to DC 12V power module; relays K1, K2, K3, K4, K5, and K6 are DC 12V; electric actuator M1 is a finished product of small reciprocating electric telescopic rod with a power of 5W; electric actuator AM3 is a finished product of reciprocating electric telescopic rod with a power of 15W; motor reduction mechanism M2 is a coaxial motor gear reducer with a power of 20W and a shaft speed of 10 revolutions per minute; touch modules W2, W3, W4, W5, W6, and W7 are model TTP223 capacitive tactile button sensor switch modules, which have two power input terminals and one power output terminal. When a finger touches the touch pad, the power output terminal outputs power, and vice versa.
