Description

Technical Field

[0001] This utility model belongs to the field of chip processing technology, specifically relating to a non-conforming product recycling device for IDSS inspection. Background Technology

[0002] IDSS testing is a parameter test for semiconductor devices such as field-effect transistors. It mainly detects the leakage current between the source and drain when the gate voltage is 0. Its purpose is to evaluate the switching performance, conduction capability and consistency of the device, determine whether the leakage current is normal, and then verify whether the core components inside the chip meet the design standards. It is a key and fundamental step in chip electrical testing.

[0003] After IDSS testing, some non-conforming products need to be recycled. Existing recycling devices usually transport non-conforming products by a single conveyor belt. Workers place the products on the conveyor belt, which moves the products forward. Once they reach the designated location, the products are removed manually or by simple mechanical structures and stacked together.

[0004] While existing equipment can recycle substandard products, it relies solely on a single conveyor belt during the recycling process, which makes it impossible to classify and process the products, resulting in low recycling efficiency. Furthermore, manual handling not only increases labor costs but also suffers from low efficiency and a high risk of errors. Additionally, the simple mechanical structure of the gripping components has poor adaptability and makes it difficult to stably grip products of different shapes, causing products to easily fall during the recycling process, resulting in insufficient safety and reliability.

Support base 3 provides a stable installation platform for handling robot 4, ensuring that it does not shake during operation. Handling robot 4, together with suction cup device 5, can automatically and accurately handle defective products, reduce manual intervention, and improve recycling efficiency. Suction cup device 5 can adapt to products of different shapes, grip firmly and not easily fall.

[0022] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, a support assembly 6 is provided inside the device platform 1. The support assembly 6 includes a support frame 601 fixedly installed inside the device platform 1. A stepper motor 602 is fixedly installed at the bottom of the support frame 601. A lead screw 604 is fixedly connected to the output end of the stepper motor 602. A lifting platform 603 is threadedly connected to the outer side of the lead screw 604.

[0023] The top of the lifting platform 603 is equipped with an array of telescopic rods. A limiting sleeve 605 is fixedly installed on the outer side of the telescopic rods and on the top of the device platform 1. The telescopic rods are movably sleeved inside the limiting sleeve 605, and a support plate 606 is fixedly connected to the top of the telescopic rods. The support frame 601 provides the mounting base. The stepper motor 602 drives the lead screw 604 to precisely raise and lower the lifting platform 603, adapting to different product heights. The telescopic rods and the limiting sleeve 605 ensure smooth and stable lifting without deviation. The support plate 606 evenly transmits support force, allowing the product to be raised smoothly, facilitating precise gripping by the handling robot 4 and improving handling efficiency. The support component 6 raises the transported product away from the conveyor belt 201, preventing severe wear between the conveyor belt 201 and the product, while also facilitating smooth handling and retrieval by the handling robot 4.

[0024] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, a support assembly 7 is provided inside the conveyor belt 201. The support assembly 7 includes a support plate 701 provided inside the conveyor belt 201. A pneumatic push rod 702 is fixedly connected to the bottom of the support plate 701, and the other end of the pneumatic push rod 702 is fixedly connected to the device platform 1.

[0025] A telescopic rod 704 is fixedly connected to the bottom of the second support plate 701. A limiting sleeve 703 is sleeved on the outside of the telescopic rod 704, and the limiting sleeve 703 is fixedly connected to the device platform 1. The telescopic rod 704 passes through the limiting sleeve 703, and a connecting block 705 is fixedly connected to the bottom of the telescopic rod 704. Support rollers 706 are symmetrically distributed on the top of the second support plate 701. The second support assembly 7, by placing the product on the second support plate 701, and then the second support plate 701 descending under the drive of the pneumatic push rod 702, causes the product to come into contact with the first conveyor belt 201 and be transported by the first conveyor belt 201, effectively improving the safety and stability of product placement.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, a rear baffle 8 is fixedly installed on the top of conveyor belt 202 and conveyor belt 303, and a rear baffle 9 is fixedly installed on the top of conveyor belt 201. The rear baffle 8 can block the products conveyed on the top of conveyor belt 202 and conveyor belt 303, thereby preventing the products from falling. The installation of the rear baffle 9 is mainly used to limit the products on the top of support plate 2701 and improve the stability of product placement.

[0027] Working principle and usage process of this utility model:

[0028] First, the defective product is placed on the support plate 701 of the internal support assembly 7 of conveyor belt 1 201. At this time, the pneumatic push rod 702 at the bottom of the support plate 701 is in an extended state, the telescopic rod 704 remains stable within the limiting sleeve 703, the connecting block 705 enhances the connection stability, and the support roller 706 at the top of the support plate 701 reduces the friction between the product and the plate. Then, the pneumatic push rod 702 retracts, causing the support plate 701 to descend, and the product moves down and comes into contact with conveyor belt 1 201. Conveyor belt 1 201 starts conveying the product. During the conveying process, the side baffle 204 at the top of conveyor belt 1 201 prevents the product from falling from both sides, and the front baffle 205 and the rear baffle 9 limit the product from the front and rear ends respectively, ensuring... To ensure stable conveying position, when the product is conveyed to the corresponding position of support component 6, the stepper motor 602 on the support frame 601 inside the device platform 1 starts, driving the lead screw 604 to rotate, which in turn drives the lifting platform 603 to rise. The telescopic rod 1 is guided within the limit sleeve 605, so that the support plate 606 smoothly lifts the product and separates it from the conveyor belt 201, avoiding friction and wear between the product and the conveyor belt. Afterwards, the handling robot 4 on the support base 3 accurately grabs the lifted product through the suction cup device 5 and transports it to the second conveyor belt 202 or the third conveyor belt 203 according to the classification requirements. The rear baffle 8 at the top of the second conveyor belt 202 and the third conveyor belt 203 prevents the product from falling, and finally completes the orderly recycling and classified conveying of unqualified products.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
