Description

Technical Field

[0001] This utility model relates to the field of multi-level screening chip technology, and in particular to a chip sorting structure with multi-level screening accuracy adjustment. Background Technology

[0002] Chip sorting structures are automated equipment composed of mechanical execution, detection and identification, and control systems. They are applied to the entire process of chip production, testing, and packaging, and can efficiently and accurately classify chips. They have advantages such as improving efficiency, ensuring quality, and adapting to large-scale production, and are key equipment in the chip industry chain.

[0003] A chip sorting structure typically consists of a mechanical actuator, a detection and identification module, and auxiliary devices. The chip sorting structure transports chips to the detection station via a conveyor system. After multi-dimensional detection, including visual and performance aspects, the control system determines the classification based on a preset algorithm and instructs the mechanical actuator to complete the sorting. At the same time, it provides real-time data feedback to ensure a stable and efficient process.

[0004] Existing chip sorting structures often fail to automatically rotate problematic chips. This is due to several issues: firstly, limited sorting flexibility, as chips with unusual pin orientations or irregular shapes are prone to jamming, collisions, or even damage to the chip or equipment due to misalignment; secondly, reduced sorting efficiency, as manual intervention may be required if problematic chips cannot smoothly enter the discharge channel, interrupting the automated process; and thirdly, poor adaptability of the discharge channel, making it difficult to meet diverse classification needs such as storing chips by defect type. To address these issues, a chip sorting structure with multi-level adjustable screening precision is proposed. Utility Model Content

The jacking mechanism includes a housing, the bottom of which is fixedly connected to the top of the conveyor belt. A motor is fixedly connected inside the housing, and an eccentric wheel is fixedly connected to the drive end of the motor. A second driving rod is slidably connected to the outer side of the eccentric wheel, and a sliding block is fixedly connected to the outer side of the second driving rod.

A cylinder is fixedly connected inside the fixed frame. A sliding rod is fixedly connected to the driving end of the cylinder. Both ends of the sliding rod are slidably connected to driving blocks. A driving rod is fixedly connected to the bottom of the driving block. A rotating plate is slidably connected to the outside of the driving rod.

[0007] This utility model has the following beneficial effects: 1. In this utility model, a motor works in conjunction with an eccentric wheel, which in turn drives a second rod. The second rod works in conjunction with a sliding block and a spring. The sliding block works in conjunction with a pusher column, which in turn works in conjunction with a pusher plate, thereby enabling the ejection of chips. This invention demonstrates significant advantages in chip sorting. By leveraging the rapid response characteristics of mechanical transmission, it can achieve instantaneous action of the pusher plate, meeting the sorting requirements of high-speed transmission lines.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figures 1 to 3 The present invention provides an embodiment of a chip sorting structure with multi-level screening accuracy adjustment, including a base plate 1. The base plate 1 serves as the basic support structure of the entire device, providing a stable mounting platform for all components above, ensuring that the working accuracy of each mechanism is not affected by overall shaking during operation. A conveyor belt 2 is fixedly connected to the top of the base plate 1. The conveyor belt 2 can carry chips and continuously transport them at a preset speed, so that the chips can pass through each subsequent processing mechanism in sequence, ensuring the continuity of the sorting process.

[0013] A collection mechanism 3 is fixedly connected to the top of the base plate 1. The collection mechanism 3 can classify and collect the sorted defective chips for subsequent centralized processing or re-inspection. A correction mechanism 4 is fixedly connected to the top of the conveyor belt 2. The correction mechanism 4 can adjust the position of the chips that have shifted during the transmission process to ensure that the chips enter the detection area in the correct posture. A detection component 5 is fixedly connected to the top of the conveyor belt 2. The detection component 5 can detect various parameters of the chips that pass through, providing a basis for sorting. A lifting mechanism 6 is fixedly connected to the top of the conveyor belt 2. The lifting mechanism 6 can remove the defective chip from the conveyor belt 2 after receiving a defective signal, thus completing the sorting action.

[0014] The jacking mechanism 6 includes a housing 61, which provides protection for the internal components and prevents external dust or debris from interfering with its operation. The bottom of the housing 61 is fixedly connected to the top of the conveyor belt 2. This connection method ensures that the relative position of the jacking mechanism 6 and the conveyor belt 2 is fixed, ensuring the accuracy of the jacking action. A motor 62 is fixedly connected inside the housing 61. The motor 62 serves as a power source and provides driving force for the operation of the jacking mechanism 6. An eccentric wheel 63 is fixedly connected to the drive end of the motor 62. When the eccentric wheel 63 rotates, it can change the contact state with the second driving rod 64 through its own eccentric structure, thereby driving the second driving rod 64.

[0015] A second driving rod 64 is slidably connected to the outer side of the eccentric wheel 63. The second driving rod 64 can convert the rotation of the eccentric wheel 63 into its own linear motion and transmit power. The outer side of the second driving rod 64 is slidably connected to the inside of the outer shell 61. The outer shell 61 can limit the movement direction of the second driving rod 64 to ensure that it slides along a preset trajectory. A sliding block 65 is fixedly connected to the outer side of the second driving rod 64. The sliding block 65 can move synchronously with the second driving rod 64 and enhance the stability of the movement of the second driving rod 64. The outer side of the sliding block 65 is slidably connected to the inside of the outer shell 61. The outer shell 61 further ensures the accuracy of the movement of the second driving rod 64 by limiting the sliding block 65. A push post 66 is fixedly connected to the outer side of the sliding block 65. The push post 66 can transmit the movement of the sliding block 65 to the push plate 68 to realize the effective transmission of power.

[0016] A push plate 68 is fixedly connected to the end of the actuating column 66 away from the sliding block 65. The push plate 68 can directly contact and push the defective chip, causing it to detach from the conveyor belt 2. Two springs 69 are fixedly connected to the outer side of the driving rod 64. The springs 69 can provide a reset pull when the eccentric wheel 63 is released, driving the driving rod 64 back to its initial position. A limiting rod 67 is fixedly connected to the end of the spring 69 away from the driving rod 64. The limiting rod 67 can provide a fixed support point for the spring 69, ensuring that the pull of the spring 69 acts stably on the driving rod 64. The outer side of the limiting rod 67 is fixedly connected to the top of the housing 61. This fixing method can ensure the stability of the position of the limiting rod 67 and provide a reliable reference for the movement of the spring 69 and the driving rod 64. A detection component 5 is fixedly connected to the top of the conveyor belt 2. The detection component 5 cooperates with the actuating mechanism 6 and can trigger the actuating action in time after detecting a defective chip.

[0017] The detection component 5 includes a bracket 51 whose bottom is fixedly connected to the top of the conveyor belt 2. The bracket 51 can provide stable installation support for the detector 52 to ensure accurate detection position. The detector 52 is fixedly connected to the outside of the bracket 51. The detector 52 can perform multi-dimensional detection on the passing chips, such as appearance and performance, to provide accurate judgment data for sorting.

[0018] Reference Figure 1 , Figure 2 and Figure 4 The correction mechanism 4 includes a fixed frame 41, which provides an installation base for other components of the correction mechanism 4, ensuring that all components work together. The bottom of the fixed frame 41 is fixedly connected to the top of the conveyor belt 2. This connection method ensures that the relative position of the correction mechanism 4 and the conveyor belt 2 is fixed, ensuring the correction effect. A cylinder 42 is fixedly connected inside the fixed frame 41. The cylinder 42 serves as a power source, providing driving force for the movement of the sliding rod 43. The driving end of the cylinder 42 is fixedly connected to the sliding rod 43. The sliding rod 43 can move up and down under the drive of the cylinder 42, thereby driving the driving block 44.

[0019] Both ends of the sliding rod 43 are slidably connected to driving blocks 44. The driving blocks 44 can convert the up-and-down movement of the sliding rod 43 into its own horizontal movement and transmit power. The top of the driving block 44 is fixedly connected to a limiting block 47. The limiting block 47 can limit the range of motion of the driving block 44 and prevent it from deviating from the preset trajectory. The outer side of the limiting block 47 is slidably connected to the inside of the fixed frame 41. The fixed frame 41 further ensures the stability of the movement of the driving block 44 by limiting the limiting block 47. The bottom of the driving block 44 is fixedly connected to a driving rod 45. The driving rod 45 can transmit the movement of the driving block 44 to the rotating plate 46 to realize power transmission.

[0020] A rotating plate 46 is slidably connected to the outer side of the driving rod 45. The rotating plate 46 can swing under the push of the driving rod 45 to adjust the chip position. The outer side of the rotating plate 46 is slidably connected to the inner side of the fixing frame 41. The fixing frame 41 can limit the swing range of the rotating plate 46 to ensure its safe movement. One end of the rotating plate 46 is rotatably connected to the top of the conveyor belt 2. This connection method can ensure that the rotating plate 46 swings stably and effectively corrects the chip on the conveyor belt 2.

[0021] The collection mechanism 3 includes a frame 31, which provides a frame for the collection box 32 and the discharge port 33, ensuring the stability of the collection structure. The bottom of the frame 31 is fixedly connected to the top of the base plate 1. This connection method can ensure the overall stability of the collection mechanism 3 and prevent the chips from falling. The frame 31 has multiple discharge ports 33 inside, which can guide different types of problematic chips into the corresponding collection box 32 for classified collection. Multiple collection boxes 32 are slidably connected inside the frame 31. The collection boxes 32 can receive problematic chips falling from the discharge port 33 for subsequent centralized processing.

[0022] Working principle: When the staff needs to sort the chips, they can place the chips on top of the conveyor belt 2. Then, the conveyor belt 2, cylinder 42, and multiple detectors 52 are started simultaneously. The chips will be moved forward by the conveyor belt 2. After the fixing frame 41 is started, the cylinder 42 will drive the sliding rod 43, causing the sliding rod 43 to push the two driving blocks 44 on both sides to the sides. Because the driving blocks 44 are set with an angle inside, the sliding rod 43 will continuously descend, pushing the driving blocks 44 outward, causing the driving blocks 44 to drive the bottom driving rod 45 together. At this time, the bottom of the driving rod 45 will slide towards one side of the rotating plate 46, causing the rotating plate 46 to slide on top of the conveyor belt 2. When it slides to a certain extent, the cylinder 42 can be controlled to pull the sliding rod 43 upward, causing the driving rod 45 to slide back to its original position. This makes the rotating plate 46 continuously swing on the surface of the conveyor belt 2, thereby preventing the chips from shifting during the sliding process.

[0023] During chip transfer, multiple detectors 52 sequentially inspect the chips. Upon detecting a chip that does not meet the requirements, the motor 62 is activated, causing it to drive the eccentric wheel 63. As the eccentric wheel 63 rotates, the second drive rod 64 loses its restraint. The second drive rod 64 is then pulled back to its original position by the stretched spring 69, which pushes the push plate 68 outward. The push plate 68 pushes the chip outward, and the chip then enters the collection box 32 through the discharge port 33, thus achieving the effect of chip inspection.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
