Description

Technical Field

[0001] The utility model relates to the technical field of chip finished product testing, in particular to a novel gravity-type chip finished product testing and sorting machine. Background Art

[0002] A chip, also known as a microcircuit, microchip, or integrated circuit (IC), is a small silicon wafer containing an integrated circuit. These chips are often part of computers or other electronic devices. However, after production, they still need to be tested and sorted to ensure their usability.

[0003] Existing chip testing typically uses gravity-type finished product testing and sorting machines. These automated sorting methods enable rapid and efficient testing and sorting of large quantities of finished products, improving production efficiency. However, gravity-type finished product testing and sorting machines are electrical testing platforms, and chip pins are often warped or damaged by tracks, foreign objects, or collisions during testing. Therefore, chip visual inspection requires the use of scanning equipment, which not only increases the number of inspection steps but also costs. Furthermore, there is no effective way to sort and collect the chips after testing and sorting. Utility Model Content

[0004] The main purpose of the utility model is to provide a new gravity-type chip finished product testing and sorting machine, which can effectively solve the above problems.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A new type of gravity-type chip finished product testing and sorting machine includes a fixed base, a No. 1 support plate is installed at the front of the upper end of the fixed base, a No. 2 support plate is installed at the rear of the upper end of the fixed base, a gravity sorting machine is installed in the middle of the upper end of the fixed base, a connecting base is installed at the right end of the fixed base, a slide groove is opened in the middle of the upper end of the connecting base, and a screening device is installed at the upper end of the slide groove.

[0007] Preferably, the screening device includes an electric telescopic rod, a mounting seat is fixedly mounted on the output end of the electric telescopic rod, a slider is mounted on the lower end of the mounting seat, the mounting seat is mounted on the chute via the slider, a No. 1 receiving box, a No. 2 receiving box, and a No. 3 receiving box are respectively mounted on the front, middle, and rear ends of the upper end of the mounting seat, and the electric telescopic rod is fixedly mounted on the rear end of the connecting seat. The electric telescopic rod pushes the mounting seat, and the mounting seat slides and adjusts on the chute via the slider at the lower end, so that the No. 1 receiving box on the mounting seat is aligned with the lower hopper to receive the chips. When the chip fails the test, the electric telescopic rod is controlled by the controller to extend and retract, so that the No. 2 receiving box receives the chips, thereby screening the chips.

[0008] Preferably, a conveyor belt is installed between the No. 1 support plate and the No. 2 support plate, and protective silicone plates are installed on the upper portions of the corresponding ends of the No. 1 support plate and the No. 2 support plate. A lower hopper is installed on the lower right ends of the No. 1 support plate and the No. 2 support plate, and a servo motor is installed on the left front end of the No. 1 support plate. The servo motor drives the conveyor belt to transport the chips, so that the chips on the conveyor belt are transported to the gravity sorting machine for testing. In addition, when the conveyor belt is transporting the chips, protective silicone plates are installed on the No. 1 support plate and the No. 2 support plate to prevent the chips from colliding with the support plates during transportation, which may cause the chip pins to be distorted or damaged.

[0009] Preferably, a controller is fixedly installed on the right end of the gravity separator, and a connecting line is installed between the controller and the gravity separator.

[0010] Preferably, there is a gap between the protective silicone plate and the conveyor belt.

[0011] Preferably, the controller is electrically connected to the electric telescopic rod and the gravity sorting machine.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Place the chips to be tested on a conveyor belt, and then use a servo motor to drive the conveyor belt to transport the chips, so that the chips on the conveyor belt are transported to a gravity sorter for testing. When the conveyor belt is transporting, protective silicone plates are set on the No. 1 support plate and the No. 2 support plate to prevent the chip pins from being distorted or damaged due to collision with the support plate during transportation.

[0014] 2. After the chip is tested, the gravity sorting machine judges the quality of the chip. When the chip passes the test, the information is transmitted to the controller through the connecting line. Then the controller drives the electric telescopic rod on the screening device, and the electric telescopic rod then pushes the mounting seat. The mounting seat then slides and adjusts on the slide groove through the slider at the lower end, so that the No. 1 receiving box on the mounting seat is aligned with the lower hopper to receive the chip. When the chip fails the test, the controller controls the electric telescopic rod to extend and retract, so that the No. 2 receiving box receives the chip, thereby screening the chip. In addition, a No. 3 receiving box is provided on the mounting seat. Its function is to receive some damaged chips that can still be recycled and repaired, so as to further screen the damaged chips.

[0023] like Figure 1-4 As shown, a new type of gravity-type chip finished product testing and sorting machine includes a fixed base 1, a No. 1 support plate 3 is installed at the front of the upper end of the fixed base 1, a No. 2 support plate 7 is installed at the rear of the upper end of the fixed base 1, a gravity-type sorting machine 4 is installed in the middle of the upper end of the fixed base 1, a connecting base 5 is installed at the right end of the fixed base 1, a slide groove 6 is opened in the middle of the upper end of the connecting base 5, and a screening device 2 is installed at the upper end of the slide groove 6.

[0024] The screening device 2 includes an electric telescopic rod 20, a mounting base 21 fixedly mounted at the output end of the electric telescopic rod 20, a slider 22 mounted at the lower end of the mounting base 21, and the mounting base 21 is mounted on the chute 6 via the slider 22. A first receiving box 23, a second receiving box 24, and a third receiving box 25 are mounted at the front, middle, and rear ends of the upper end of the mounting base 21, respectively. The electric telescopic rod 20 is fixedly mounted at the rear end of the upper end of the connecting base 5. The electric telescopic rod 20 then pushes the mounting base 21, which then slides and adjusts on the chute 6 via the slider 22 at the lower end, so that the first receiving box 23 on the mounting base 21 is aligned with the lower hopper 32 to receive the chips. If the chip fails the test, the controller 40 controls the electric telescopic rod 20 to extend and retract, causing the second receiving box 24 to receive the chips, thereby screening the chips.

Moreover, when the conveyor belt 30 is transporting, the No. 1 support plate 3 and the No. 2 support plate 7 are both provided with a protective silicone plate 31 to prevent the chip from colliding with the support plate during transportation, which may cause the chip pins to be crooked or damaged. After the chip is tested, the gravity sorting machine 4 makes a judgment on the quality of the chip. When the chip passes the test, the information is transmitted to the controller 40 through the connecting line 41. , then the controller 40 drives the electric telescopic rod 20 on the screening device 2, and the electric telescopic rod 20 then pushes the mounting seat 21, and the mounting seat 21 then slides and adjusts on the slide groove 6 through the slider 22 at the lower end, so that the No. 1 receiving box 23 on the mounting seat 21 is aligned with the lower hopper 32 to receive the chips.

In addition, a No. 3 receiving box 25 is also provided on the mounting seat 21, which is used to receive some damaged chips that can still be recycled and repaired, so as to further screen the damaged chips.
