A defective chip rejection device for chip inspection

Abstract

This invention discloses a defective chip rejection device, comprising a body and a conveyor belt. The conveyor belt is movably connected to the inner side of the body, and a drive motor for the conveyor belt is installed on the outer side of the body. A bridge is fixedly connected to a point on the top surface of the body, and a lens is mounted on the bridge. A notch is provided at a point on the body, and a slider is movably connected to the notch. The advantages of this invention are: when the vision system detects a defective chip, the piston rod of the electric cylinder quickly extends, pushing the bending pusher to rotate clockwise, forcing the pusher plate down to contact the conveyor belt, and pushing the defective chip laterally into the inclined stainless steel slide. The low-friction characteristics of the slide ensure that the defective chip slides smoothly into the recycling container. The dynamic avoidance design ensures that the pusher plate only contacts the conveyor belt at the moment of rejection, completely solving the space occupation problem of traditional direct-push mechanisms and significantly improving the smoothness of chip transport.

Description

Technical Field

[0001] This utility model relates to the field of chip testing technology, and in particular to a defective chip rejection device for chip testing. Background Technology

[0002] In chip manufacturing, the defect rejection device is a critical piece of equipment for ensuring product quality. Traditional rejection mechanisms mostly employ a direct-push structure, where a pusher plate is directly driven laterally by a cylinder or electric cylinder to eject defective chips. However, in this type of structure, the pusher plate still occupies space on the side of the conveyor belt during reset, which can easily interfere with subsequent normal chips, causing transport stagnation or positioning misalignment, thus affecting detection efficiency. Furthermore, the rigid impact of the direct-push mechanism can easily damage the chip surface. Therefore, there is an urgent need for a rejection mechanism that can completely avoid the conveyor channel in the non-rejection state. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0004] Therefore, one objective of this utility model is to provide a defective chip rejection device for chip inspection, so as to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, one embodiment of the present invention provides a defective chip inspection rejection device, including a body and a conveyor belt. The conveyor belt is movably connected to the inner side of the body, and a drive motor for the conveyor belt is installed on the outer side of the body.

[0006] A bridge frame is fixedly connected to a point on the top surface of the body, and a lens is mounted on the bridge frame.

[0007] A notch is provided at one point on the body, and a slider is movably connected to the notch;

[0008] A push block is movably connected to the end corner of the slider, and a push plate is fixedly connected to the end of the push block;

[0009] The bottom of the pusher plate is movably connected to the conveyor belt;

[0010] The push block is bent, and an electric cylinder is installed on the top of the machine body. A connector is fixedly connected to the end of the output end of the electric cylinder, and the inner side of the connector is movably connected to the top of the push block.

[0011] When the output end of the electric cylinder retracts, the push block is lifted. A slide is fixedly connected to the outer side of the machine body, and the slide is connected to the notch.

[0012] Preferably, in any of the above solutions, the machine body and the bridge are connected by screws, and the conveyor belt is made of PU.

[0013] The above technical solution employs a device comprising a main body, a PU material conveyor belt, and a drive motor, the conveyor belt being driven by the drive motor to rotate in a cycle. A bridge is mounted on the top of the main body, fixed to the inspection station with screws, and its mounted vision lens faces the surface of the conveyor belt to identify chip defects.

[0014] At the rejection station, a rectangular notch is cut into the side wall of the machine body, and a horizontally sliding slider is embedded in the notch. The front end of the slider is connected to a 90° bent push block via a hinge shaft. A push plate is welded to the end of the push block, and the bottom of the push plate maintains a clearance fit with the conveyor belt. The top of the bent push block is hinged to the output end of a horizontally mounted electric cylinder, and the end of the electric cylinder is movably connected to the push block via a riveted joint.

[0015] Preferably, in any of the above embodiments, the drive motor is mounted horizontally, and the lens's shooting direction is towards the conveyor belt.

[0016] Standby state (electric cylinder retraction): When the electric cylinder piston rod retracts, the push block is pulled and bent by the joint and flipped up around the hinge point, so that the push block and push plate are raised to the tilted avoidance position. At this time, the push plate is completely separated from the surface of the conveyor belt, ensuring that normal chips pass through without obstruction.

[0017] The rejection action (electric cylinder extension) occurs when the vision system detects a defective item. The electric cylinder piston rod extends rapidly, pushing a bending pusher block to rotate clockwise. This forces the pusher plate down until it contacts the conveyor belt, pushing the defective item laterally into an inclined stainless steel chute. The low-friction characteristics of the chute ensure that the defective item slides smoothly into the recycling container.

[0018] Preferably, in any of the above embodiments, the slider is located below the electric cylinder, and the bending angle of the push block is ninety degrees.

[0019] Innovative Advantages: Dynamic Avoidance Design: The pusher only contacts the conveyor belt at the moment of rejection, completely solving the space occupation problem of traditional direct push mechanisms and greatly improving the smoothness of chip delivery;

[0020] Buffer protection mechanism: The lever structure of the bent pusher can reduce the linear impact force of the electric cylinder, and together with the elastic surface of the PU conveyor belt, it can effectively prevent the chip from being damaged during the rejection process;

[0021] Preferably, in any of the above schemes, the push block is welded to the push plate, and the electric cylinder is installed horizontally.

[0022] Preferably, in any of the above solutions, the connector is riveted to the end of the electric cylinder output, the slide rail is made of stainless steel, and the slide rail is inclined.

[0023] The connector is movably connected to the push block through a slot, thereby enabling the push block to flip up and press down when the connector moves back and forth.

[0024] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0025] This chip inspection defective product rejection device, through the coordinated arrangement of a conveyor belt, drive motor, bridge, lens, notch, slider, pusher block, pusher plate, electric cylinder, connector, and slide rail, works as follows: When the vision system detects a defective product, the electric cylinder piston rod quickly extends, pushing the bent pusher block to rotate clockwise, forcing the pusher plate down to contact the conveyor belt, and pushing the defective product laterally into the inclined stainless steel slide rail. The low-friction characteristics of the slide rail ensure that the defective product slides smoothly into the recycling container. The dynamic avoidance design ensures that the pusher plate only contacts the conveyor belt at the moment of rejection, completely solving the space occupation problem of traditional direct push mechanisms and significantly improving the smoothness of chip delivery.

[0036] A bridge 4 is fixedly connected to a point on the top surface of the body 1, and a lens 5 is mounted on the bridge 4.

[0037] A notch 6 is provided at one point on the body 1, and a slider 7 is movably connected at the notch 6;

[0038] A push block 8 is movably connected to the end corner of the slider 7, and a push plate 9 is fixedly connected to the end of the push block 8;

[0039] The bottom of the push plate 9 is movably connected to the conveyor belt 2;

[0040] The push block 8 is bent, and an electric cylinder 10 is installed on the top of the machine body 1. The end of the output end of the electric cylinder 10 is fixedly connected to a connector 11, and the inner side of the connector 11 is movably connected to the top of the push block 8.

[0041] When the output end of the electric cylinder 10 retracts, the push block 8 is lifted. The outer side of the machine body 1 is fixedly connected to the slide rail 12, and the slide block 12 is connected to the notch 6.

[0042] Example 1: The machine body 1 and the cable tray 4 are connected by screws, and the conveyor belt 2 is made of PU. The device includes the machine body 1, the PU conveyor belt 2, and the drive motor 3. The conveyor belt 2 is driven by the drive motor 3 to rotate in a cycle. The cable tray 4 is provided on the top of the machine body 1. The cable tray 4 is fixed above the inspection station by screws. The vision lens 5 mounted on it faces the surface of the conveyor belt 2 and is used to identify chip defects.

[0043] At the rejection station, a rectangular notch 6 is formed on the side wall of the machine body 1, and a horizontally sliding slider 7 is embedded in the notch 6. The front end of the slider 7 is connected to a 90° bent push block 8 via a hinge shaft. A push plate 9 is welded to the end of the push block 8, and the bottom of the push plate 9 maintains a clearance fit with the conveyor belt 2. The top of the bent push block 8 is hinged to the output end of a horizontally mounted electric cylinder 10, and the end of the electric cylinder 10 is movably connected to the push block 8 via a riveted joint 11.

[0044] Example 2: The drive motor 3 is horizontally mounted, and the lens 5 faces the conveyor belt 2. The slider 7 is located below the electric cylinder 10, and the bending angle of the push block 8 is 90 degrees. The push block 8 is welded to the push plate 9, and the electric cylinder 10 is horizontally mounted. The connector 11 is riveted to the end of the output end of the electric cylinder 10, and the slide rail 12 is made of stainless steel and is inclined.

[0045] The working principle of this utility model is as follows:

[0046] Standby state (electric cylinder 10 retracts): When the piston rod of electric cylinder 10 retracts, it pulls and bends the push block 8 around the hinge point through the connector 11, so that the push block 8 and the push plate 9 are raised to the tilted avoidance position. At this time, the push plate 9 is completely separated from the surface of the conveyor belt 2, ensuring that normal chips pass through without obstruction.

[0047] The rejection action (electric cylinder 10 extends): When the vision system detects a defective product, the piston rod of the electric cylinder 10 extends rapidly, pushing the bending pusher 8 to rotate clockwise, forcing the pusher plate 9 down to contact the conveyor belt 2, and pushing the defective product laterally into the inclined stainless steel slide 12. The low-friction characteristics of the slide 12 ensure that the defective product slides smoothly into the recycling container.

[0048] In implementation, the chips on conveyor belt 2 are first optically inspected by lens 5 on bridge 4. The control system triggers electric cylinder 10 based on the detection signal. When a defective chip reaches the corresponding position of notch 6, electric cylinder 10 completes its extension-retraction stroke within 0.1 seconds, and pusher plate 9 quickly completes its push-down-reset action, with a single rejection cycle of less than 0.5 seconds. The tilt angle of slide 12 is preferably 30°-45°, and it is made of mirror-finished stainless steel to reduce frictional resistance. This device is particularly suitable for high-speed production lines for thin chips with a thickness of less than 1mm.

[0049] Compared with the prior art, the present invention has the following advantages:

[0050] This chip inspection defective product rejection device, through the coordinated arrangement of conveyor belt 2, drive motor 3, bridge 4, lens 5, notch 6, slider 7, push block 8, push plate 9, electric cylinder 10, connector 11, and slide rail 12, when the vision system detects a defective product, the piston rod of electric cylinder 10 quickly extends, pushing the bent push block 8 to rotate clockwise, forcing the push plate 9 to press down until it contacts the conveyor belt 2, pushing the defective product laterally into the inclined stainless steel slide rail 12. The low-friction characteristics of slide rail 12 ensure that the defective product slides smoothly into the recycling container. The dynamic avoidance design: the push plate 9 only contacts the conveyor belt 2 at the moment of rejection, completely solving the space occupation problem of traditional direct push mechanisms, and greatly improving the smoothness of chip delivery.
