Description

Technical Field

[0001] This utility model relates to the field of chip testing and sorting machine technology, and in particular to a chip testing and sorting machine. Background Technology

[0002] IC chips are small chips that integrate a large number of microelectronic components such as transistors, microcircuits, capacitors and other electronic devices, and are built on a plastic base. After the IC chips complete the processing and manufacturing process, they need to be tested and classified one by one. The first step is to test whether the chip can read data normally. Classifying and storing chips is conducive to their rational use. Testing and classification require the use of testing and sorting devices.

[0003] A search revealed that patent CN218133421U discloses a chip testing and sorting machine, but this sorting machine has the following shortcomings in use:

[0004] In use, the chip is positioned and blocked by a chip positioning baffle, and then the chip test contact is moved downward by a second electric cylinder to test the chip. However, the chips are of different sizes, and when blocked by the chip positioning baffle, it is not possible to ensure that the chip is directly facing the chip test contact, making it inconvenient to test. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where chips are positioned and blocked by a chip positioning baffle, and then the chip test contact is moved downward by a second electric cylinder to test the chip. However, chips have different sizes, and it is impossible to ensure that the chip is directly facing the chip test contact when blocked by the chip positioning baffle, making it inconvenient for testing. Therefore, this invention proposes a chip testing and sorting machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A chip testing and sorting machine includes a conveyor frame and chip testing contacts for testing chips. A first frame is fixedly mounted on the top of the conveyor frame, and a second electric push rod for adjusting the height of the chip testing contacts is provided below the first frame. A mounting plate is fixedly mounted on the telescopic part of the second electric push rod. The chip testing contacts are mounted on the bottom of the mounting plate by bolts. A bracket is fixedly mounted on one end of the conveyor frame, and two sorting boxes for placing the tested chips are provided on the bracket. A positioning mechanism is provided on the conveyor frame, which can position the chips and keep them in the center position when the conveyor frame transports the chips.

[0008] To facilitate chip testing, a moving mechanism is also included, which can move the chip test contacts.

[0009] In one possible design, the positioning mechanism includes two fixed plates and two positioning plates. The bottom of the two fixed plates is fixedly connected to the top two sides of the conveyor frame, respectively. A third electric push rod is fixedly installed on one side of the fixed plate. The telescopic parts of the two third electric push rods pass through one side of the two fixed plates, respectively. The two positioning plates are fixedly connected to the telescopic parts of the two third electric push rods, respectively.

[0010] In one possible design, the moving mechanism includes a concave plate, a first motor, and a lead screw. The top of the concave plate is fixedly connected to the top inner wall of the first frame. One side of the first motor is fixedly connected to one side of the concave plate. One end of the lead screw is rotatably connected to the inner wall of one side of the concave plate. The output end of the first motor passes through one side of the concave plate and is fixedly connected to the other end of the lead screw. A moving block is slidably connected to the top inner wall of the concave plate. A lead screw nut is embedded in one side of the moving block. The lead screw nut is threadedly connected to the lead screw. The fixed part of the second electric push rod is fixedly connected to the bottom of the moving block.

[0011] In one possible design, a second frame is fixedly mounted on the top of the conveyor frame, a second frame is fixedly mounted on the top inner wall of the second frame, a second motor is fixedly mounted on the bottom inner wall of the second frame, and the output end of the second motor passes through the bottom of the second frame and is fixedly mounted with a rotating plate for sorting chips.

[0012] In one possible design, a first frame is fixedly mounted on the top of the bracket. The first frame is U-shaped, and a top plate for adjusting the height of the sorting boxes is slidably connected to the inner wall of the first frame. Both sorting boxes are placed on top of the top plate. A driving component for moving the top plate is fixedly mounted on the bottom of the bracket. The telescopic part of the driving component passes through the top of the bracket and is fixedly connected to the bottom of the top plate.

[0013] In one possible design, a short plate is fixedly installed on one side of the first frame, and a first electric push rod is fixedly installed on the top of the short plate. The telescopic part of the first electric push rod passes through the bottom of the short plate and is fixedly installed with a baffle for blocking the chip.

[0014] In one possible design, the same first drive roller is rotatably connected to the inner walls of both sides of the conveyor frame, and the same second drive roller is rotatably connected to the inner walls of both sides of the conveyor frame. The first drive roller and the second drive roller are driven by the same conveyor belt. A third motor for driving the first drive roller to rotate is fixedly installed on one side of the conveyor frame. The output end of the third motor passes through one side of the conveyor frame and is fixedly connected to one end of the first drive roller.

[0015] In this application, during use, firstly, the distance between the two positioning plates is adjusted according to the size of the chip. Then, two third electric push rods are activated, and their telescopic parts push the two positioning plates towards the center to position the chip, keeping it in the center of the conveyor frame. After adjusting the fitting distance, the chip is placed on the conveyor belt between the two positioning plates. The third motor is then activated, driving the first transmission roller to rotate. Since the first and second transmission rollers are connected via the conveyor belt, the conveyor belt begins to operate, and the chip is conveyed forward along with it. The baffle is initially positioned on the conveyor belt. When the chip is conveyed to the baffle position... At this time, the chip is blocked by the baffle, and the conveyor belt stops conveying it. The chip and the chip test contact are at the same horizontal level. Then, the first motor is started, and its output drives the lead screw to rotate. The moving block moves along the lead screw, thereby moving the second electric push rod and the chip test contact. This positions the chip test contact above the chip. The second electric push rod is then activated, and its telescopic part pushes the mounting plate downwards, which in turn moves the chip test contact downwards, so that its bottom contact makes contact with the top contact of the chip. This allows for chip testing, facilitating the determination of whether the chip can read data normally. Note that... The system can be configured so that if the chip test contact and the chip cannot be aligned after the chip is blocked by the baffle, the third motor can be reversed to move the chip below the chip test contact. After the test is completed, the first electric push rod is activated, which drives the baffle to rise and release the blockage. The conveyor belt continues to transport the chip. When the chip is about to be transported to the rotating plate, the second motor is activated, which drives the rotating plate to rotate. Based on the chip's test results, the rotating plate rotates the chip to the corresponding direction, so that the chip is transported to one side of the conveyor belt. Personnel can then place the chips in the sorting boxes for classification. To facilitate the operation of operators in picking up and placing chips in the sorting boxes and to accommodate classification at different heights, the system is designed to be flexible. The system requires the activation of a drive mechanism, whose telescopic part pushes the top plate up or down along the inner wall of the first frame, thereby adjusting the height of the sorting box. The drive mechanism can be one of an electric push rod, a pneumatic cylinder, or a hydraulic cylinder, which can be selected according to needs. It should be noted that the first motor, second motor, third motor, first electric push rod, second electric push rod, third electric push rod, and drive mechanism all require an external power supply and an external controller for operation. The first motor, second motor, and third motor can be stepper motors, which can rotate in both directions. The specific type can be selected according to needs. The material, specifications, and type of the lead screw can also be selected according to needs.

[0016] The beneficial effects of this utility model are as follows:

[0017] In this utility model, the chip testing and sorting machine, by setting a positioning mechanism, uses two third electric push rods to push two positioning plates to move towards the center. The distance between the two positioning plates can be adjusted according to the different sizes of chips, thereby ensuring that the chip always stays in the center position of the conveyor frame during the conveying process. This precise positioning method effectively solves the problem of inaccurate chip positioning in the prior art, so that the chip testing contacts can contact the chip more accurately, thereby improving the accuracy and reliability of chip testing.

[0018] In this utility model, the chip testing and sorting machine uses a moving mechanism. A first motor drives a lead screw to rotate, which in turn drives a moving block to move along the lead screw. This, in turn, drives a second electric push rod and a chip testing contact to move flexibly. This design allows the chip testing contact to be finely adjusted according to the specific position of the chip, ensuring accurate docking between the testing contact and the chip contact, and further improving the flexibility and adaptability of the test.

[0019] In this invention, the positioning mechanism can adjust the distance between the two positioning plates according to the different sizes of chips, thereby ensuring that the chip always stays in the center position of the conveyor frame during the conveying process. The moving mechanism enables the chip test contact to be finely adjusted according to the specific position of the chip, ensuring accurate docking between the test contact and the chip contact, further improving the flexibility and adaptability of the test.
