Description
A chip sorting and detection auxiliary device Technical Field
[0001] This utility model relates to the field of chip sorting and detection technology, and specifically discloses a chip sorting and detection auxiliary device. Background Technology
[0002] As commonly used electronic components, chips require testing after production. The finished products are then placed in testing facilities for inspection, and those that fail the tests are removed. Therefore, chip sorting and testing auxiliary devices are needed.
[0003] Current mainstream chip sorting and inspection devices typically consist of the following core modules;
[0004] Single-station testing station: A fixed testing head works in conjunction with a vacuum adsorption stage to complete the electrical performance testing of the chip. Four-axis robotic arm: A pneumatic gripper picks up the chip and transfers it to the sorting station. Independent flipping sorting mechanism: A servo motor-driven rotary table performs a 180° flipping motion after receiving a command. Linear conveyor track: Transports the sorted chips to the corresponding collection boxes. The workflow is as follows: The robotic arm picks up the chip from the feed tray to the testing station, and the testing takes 1.5-2 seconds. After the testing is completed, the robotic arm transfers the chip to the sorting station (takes 0.8 seconds). The flipping mechanism performs the sorting action according to the test results (takes 1.2 seconds). Qualified products enter the first collection box, and unqualified products enter the second collection box. The robotic arm returns to the initial position and waits for the next cycle to start.
[0005] Existing sorting devices are usually single-station inspection or static dual-station designs, which have low sorting efficiency and the same flip axis is shared by qualified and unqualified products, making it impossible to achieve differentiated sorting paths. Therefore, a chip sorting and inspection auxiliary device is needed to solve this problem. Summary of the Invention
[0006] This utility model proposes a chip sorting and detection auxiliary device, which facilitates the simultaneous completion of detection and sorting actions during movement, breaking through the limitation of traditional equipment requiring machine stoppage and repositioning. Furthermore, it achieves differentiated sorting paths by triggering a flipping action through slide rail displacement (qualified products flip in place, unqualified products flip after repositioning), thereby reducing invalid travel through path differentiation.

A second collection frame is placed on the upper end of the base between the two first collection frames.

The output ends of the two electric push rods pass through the fixed plates and are fixedly connected to the mounting plates.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.
[0028] Please refer to Figures 1-4. A chip sorting and detection auxiliary device includes a base 1 and a detection head 3. A dual-station dynamic mechanism is provided above the base 1.
[0029] The dual-station dynamic mechanism includes a U-shaped frame 4 fixedly connected to the upper end of the base 1. An electric guide rail 5 is installed inside the U-shaped frame 4. A slider 6 is slidably connected to the outer wall of the electric guide rail 5. A support plate 7 is fixedly connected to the front end of the slider 6. Two left-right distributed rotating shafts 9 are rotatably connected to the front end of the support plate 7. A horizontal plate 10 is fixedly connected to the front end of each of the two rotating shafts 9. Two left-right symmetrically distributed first collection frames 11 are placed at the upper end of the base 1. A second collection frame 12 located between the two first collection frames 11 is placed at the upper end of the base 1.
[0030] Limiting mechanisms are provided at the upper ends of both horizontal plates 10.
[0031] In this embodiment: the external robotic arm places the chip to be tested within the limiting mechanism of the horizontal plate 10, the electric push rod 14 pushes the rubber plate 16 to clamp the chip, the pressure sensor 15 provides real-time pressure feedback, and the detection head 3 performs electrical parameter testing on the chip. If the test is qualified, the right worm gear reducer motor 8 drives the horizontal plate 10 to rotate 180° in place, and the chip falls vertically into the second collection frame 12. The dual-station cycle alternates to achieve uninterrupted production. If the test is abnormal, the electric guide rail 5 drives the slider 6 to move to the right, so that the left horizontal plate 10 reaches the detection station, and at the same time the right horizontal plate 10 moves to the sorting station to perform a 180-degree rotation, and the chip enters the first collection frame 11 along a parabolic trajectory.
[0032] As a technical optimization of this utility model, two worm gear reducers 8 distributed on the left and right are installed at the rear end of the support plate 7. The output ends of the two worm gear reducers 8 pass through the support plate 7 and are fixedly connected to two rotating shafts 9 respectively.
[0033] In this embodiment, the worm gear reducer motor 8 can easily drive the rotating shaft 9 to rotate.
[0034] As a technical optimization of this utility model, the limiting mechanism includes two fixed plates 13 that are fixedly connected to the upper end of the horizontal plate 10 and distributed in front and behind. Electric push rods 14 are installed on the opposite sides of the two fixed plates 13. The output ends of the two electric push rods 14 pass through the fixed plates 13 and are fixedly connected to the mounting plates 18. Pressure sensors 15 are installed on the opposite sides of the two mounting plates 18. Rubber plates 16 are fixedly connected to the opposite sides of the two pressure sensors 15.
[0035] In this embodiment, two electric actuators 14 can drive the mounting plate 18, pressure sensor 15 and rubber plate 16 connected to them to move relative to each other, thereby clamping and fixing the chip.
[0036] As a technical optimization of this utility model, an equilateral triangular protrusion is provided at one end of the two rubber plates 16 facing each other, the protrusion height is 0.3-0.5mm, and the surface of the rubber plate 16 is coated with a diamond carbon film 17.
[0037] In this embodiment: the chip slip ratio can be reduced to <0.5% by using equilateral triangular protrusions, while electrostatic adsorption can be avoided by using diamond carbon film 17.
[0038] As a technical optimization of this utility model, the inner walls of the two first collection frames 11 and the second collection frame 12 are provided with a plurality of evenly distributed silicone damping columns.
[0039] In this embodiment, the impact force after the chip is dropped can be reduced by using silicone damping pillars.
[0040] As a technical optimization of this utility model, the front end of the base 1 is fixedly connected to the bracket 2, and the detection head 3 is set at the top inside the bracket 2.
[0041] In this embodiment, the detection head 3 can be easily supported by the bracket 2.
[0042] As a technical optimization of this utility model, a PLC controller is installed at the front end of the bracket 2.
[0043] In this embodiment, the PLC controller is electrically connected to the worm gear reducer motor 8, the electric actuator 14, the pressure sensor 15, and the electric guide rail 5, so that the operation of each component can be controlled by the PLC controller.
[0044] In this embodiment: During use, the chip to be tested is first placed into the limiting mechanism of the horizontal plate 10 by an external robotic arm. There are two external robotic arms, located on the left and right sides of the base 1 respectively. The left external robotic arm is responsible for placing the chip on the left horizontal plate 10, and the right external robotic arm is responsible for placing the chip on the right horizontal plate 10. The slider 6 is driven to the left by the electric guide rail 5, so that the right horizontal plate 10 reaches the detection station. Then, the rubber plate 16 is pushed by the electric push rod 14 to clamp the chip. The pressure sensor 15 provides real-time pressure feedback. The detection head 3 performs electrical parameter testing on the chip. If the test is qualified... The right-side worm gear reducer motor 8 drives the horizontal plate 10 to rotate 180° in place, and the chip falls vertically into the second collection box 12. The dual-station cycle alternates to achieve uninterrupted production. If an abnormality is detected, the electric guide rail 5 drives the slider 6 to move to the right, so that the left horizontal plate 10 reaches the detection station. At the same time, the right horizontal plate 10 moves to the sorting station and performs a 180-degree rotation. The chip enters the right first collection box 11 along a parabolic trajectory. The qualified chips at the top of the left horizontal plate 10 fall into the second collection box 12 in the same way, and the unqualified chips fall into the left first collection box 11.
