Description

Technical Field

[0001] The present invention relates to the technical field of integrated circuit processing, in particular to an automatic loading integrated circuit packaging detection device. Background Art

[0002] When working, integrated circuits have the functions of analog signal processing and digital signal processing. They also have the functions of equipment control, system control and coordination, and are also used in data storage. The chip is the carrier of the integrated circuit, and the two complement each other. The production of integrated circuits includes the steps of appearance inspection and power-on inspection of the chip. That is, during the packaging and processing of the integrated circuit, the chip needs to be inspected for appearance and power-on to ensure the safety and stability of the chip. During the inspection, the chip is placed on an automatic probe table, fixed by negative pressure adsorption, and then the probe is in contact with the chip for power-on inspection. During the chip inspection process, if the chip being inspected is unqualified, the chip may smoke or even catch fire. If it is not handled in time, it will affect subsequent work.

[0003] In order to overcome the above defects, the prior art (Chinese patent application with application number 202120680789.5 and application date 2021-04-02) is an integrated circuit chip detection device with a safety protection function. When in use, the upper seal cover can be pulled up and the integrated circuit chip can be inserted into the seal cavity seat and the inner side of the upper seal cover. At this time, the upper seal cover is released and the elastic force is used to press the upper seal cover down to clamp and press the chip, which is convenient for fixing the chip for stable detection. At the same time, the connecting pin is made of rubber and has insulating properties. The seal cavity seat and the bench test seat can be connected by the connecting pin so that they can be assembled and used. At the same time, the connection of the seal cavity seat can be insulated from the main body, which is convenient for the chip to be tested when it is powered on. It has a protective effect, but when the chip inspection fails, smoke and fire occur, and the odor will be inhaled by the human body, which will affect the health of the operator.

[0015] Compared with the prior art, the present invention has the following beneficial effects: it adopts a new structural design, and during the detection process, when the chip emits smoke or catches fire, the sound reminder component can be set to make the sound piece emit intermittent sound, which plays a prompt and warning role. In addition, a smoke and dust adsorption component is provided, so that the smoke and odor can be absorbed by the adsorption head, ensuring the safety of the detection environment and protecting the health of the staff. In addition, a cleaning component is provided to clean the dust and impurities caused by the chip abnormality, ensuring the normal progress of subsequent detection work. The specific contents are as follows:

[0016] (1) The automatic loading integrated circuit packaging inspection equipment, when working, places the chip to be inspected in the material box above the workbench, and uses a robotic arm to clamp the chip and place it on the negative pressure adsorption plate. The robotic arm realizes automatic loading, and then realizes appearance inspection through the camera, and completes power-on inspection through the automatic probe board, with high work efficiency.

[0017] Furthermore, when the chip smokes, the motor works and drives the cam to rotate. At this time, the cam will intermittently push the force plate, and then the force plate will drive the upper connecting plate and the knocking rod to do reciprocating linear motion in the vertical direction under the action of the cam thrust, the lower connecting rod and the connecting spring, as well as its own gravity. At this time, the knocking rod will intermittently knock the sound piece, and then the sound piece will intermittently make a sound, which serves as a warning and emphasis, facilitates timely handling by the staff, and improves safety.

[0018] (2) When the chip smokes, the automatic loading integrated circuit packaging detection equipment will start the adsorption head to absorb the smoke, so that the smoke and odor will not affect the workers, thus ensuring the health of the workers and the working environment.

[0019] Furthermore, when the force-bearing plate makes reciprocating linear motion in the vertical direction, the force-bearing plate drives the external rod to move synchronously. When the external rod descends, it pushes the side plate. When the external rod rises, the side plate returns to its original position. At this time, the side plate makes reciprocating linear motion in the horizontal direction under the action of the thrust of the external rod, the fixed block and the limit rod and the reset spring. At this time, the side plate drives the slide plate and the adsorption head to move synchronously, thereby increasing the working range of the adsorption head, which can better handle smoke and odor. When the adsorption head is working, the smoke and odor are discharged through the transition pipe.

[0020] (3) The automatic loading integrated circuit packaging detection equipment, when the force plate drives the external rod to make reciprocating linear motion in the vertical direction, the external rod drives the pressure plate to move synchronously, and when the pressure plate descends, the pressure plate squeezes the airbag, at which time the airbag sprays a special cleaning agent through the nozzle, and when the pressure plate rises, the airbag is not squeezed, and at this time the airbag is expanded by suction through the feed pipe, and then during the working process, when the pressure plate intermittently squeezes the airbag, the airbag will intermittently spray a special cleaning agent, which can clean the workbench and the negative pressure adsorption plate in advance, making it convenient for the staff to do subsequent cleaning work.

[0021] Furthermore, during the process of the airbag spraying the cleaning agent through the nozzle and inhaling air through the feed pipe, the one-way valve prevents the cleaning agent from being sprayed out from the feed pipe, so that the working direction of the special cleaning agent is from the airbag to the nozzle, ensuring the stability of the operation of the airbag and the nozzle. At the same time, when the special cleaning agent inside the airbag is consumed, special cleaning agent can be added to the inside of the airbag through the feed pipe.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Embodiment 1: By setting a sound reminder component, during the detection process, when the chip has abnormal conditions such as smoke and fire, a sound can be emitted through the sound piece 10, which plays a warning and reminder role and improves safety. Figure 1-Figure 5 As shown, it includes a workbench 1, the upper surface of the workbench 1 is bolted to a robotic arm 2, and the upper surface of the workbench 1 is bolted to a camera 3, and the internal bolts of the workbench 1 are connected to a negative pressure adsorption plate 4, the upper surface of the workbench 1 is fixedly connected to a work plate 5, and the left surface of the work plate 5 is movably connected to an automatic probe plate 8 through an electric slide rail, and a sound reminder component is provided on the right side of the work plate 5, and the sound reminder component includes an auxiliary plate 6 fixedly connected to the right side of the work plate 5, and the sound reminder component will make a sound when working.

[0035] The sound reminder component also includes a motor 7 fixedly connected to the right side surface of the auxiliary plate 6, and the output end of the motor 7 is fixedly connected to the cam 9, and the lower surface of the auxiliary plate 6 is fixedly connected to the lower connecting rod 12, and the upper surface of the auxiliary plate 6 is fixedly connected to the sound piece 10, the motor 7 and the camera 3 are connected for electrical signals, the lower connecting rod 12 is symmetrically distributed about the center of the auxiliary plate 6, and the end of the lower connecting rod 12 is fixedly connected to the partition 13, and the surface of the lower connecting rod 12 is slidably provided with a force plate 11.

[0036] The upper surface of the partition 13 is fixedly connected to a connecting spring 14, and the other side of the connecting spring 14 is fixedly connected to the lower surface of the force-bearing plate 11, and the upper surface of the force-bearing plate 11 is fixedly connected to an upper connecting plate 15, the front view of the upper connecting plate 15 is an inverted "L" structure, and the lower surface of the upper connecting plate 15 is fixedly connected to a knocking rod 16. A smoke adsorption assembly is provided on the left side of the working plate 5, and the smoke adsorption assembly includes a slide plate 18 and an adsorption head 22 movably arranged on the left side of the working plate 5. When the smoke adsorption assembly is working, it will suck away the smoke and dust during the detection process.

[0037] During operation, the chip to be tested is placed in the material box above the workbench 1, and the chip is clamped and placed on the negative pressure adsorption plate 4 by the robot arm 2. Automatic loading is achieved through the robot arm 2, and then the appearance inspection is achieved through the camera 3, and then the power-on inspection is completed through the automatic probe board 8. The work efficiency is high. When the chip smokes, the motor 7 works and drives the cam 9 to rotate. At this time, the cam 9 will intermittently push the force plate 11. When the force plate 11 is pushed by the cam 9, the force plate 11 rises. At this time, the connecting spring 14 is stretched, and when the cam 9 is not pushed, the force plate 11 is connected. The connecting spring 14 and the lower connecting rod 12 descend to their original position, and the above process is repeated. Under the action of the thrust of the cam 9, the lower connecting rod 12, the connecting spring 14 and its own gravity, the force-bearing plate 11 drives the upper connecting plate 15 and the knocking rod 16 to make reciprocating linear motion in the vertical direction. At this time, the knocking rod 16 will intermittently knock the sound piece 10, and then the sound piece 10 will intermittently make a sound, which serves as a warning and emphasis, facilitates timely handling by the staff, and improves safety. During the movement of the force-bearing plate 11, the partition 13 plays a role in limiting the moving distance of the force-bearing plate 11, thereby ensuring stability.

[0038] Embodiment 2: The difference from embodiment 1 is that, by setting the smoke adsorption component, the adsorption head 22 can absorb the smoke and odor generated by the chip abnormality during operation, ensuring the safety of the work. At the same time, the adsorption head 22 is in a swinging state, with a wider working range and higher working efficiency. Figure 6-Figure 9 As shown, the smoke adsorption assembly also includes an external rod 17 fixedly connected to the left end of the force-bearing plate 11, and the lower surface of the external rod 17 is fitted with a side plate 24, and the end of the side plate 24 is fixedly connected to the slide plate 18, and the surface of the side plate 24 is inclined.

[0039] The adsorption heads 22 are fixedly connected to the surface of the slide 18 at equal intervals, and the surface of the slide 18 is fixedly connected to a fixed block 19, the inner wall of the working plate 5 is fixedly connected to a limiting rod 20, and the limiting rod 20 and the fixed block 19 are movably connected, the surface of the fixed block 19 is fixedly connected to a return spring 21, and the other side of the return spring 21 is fixedly connected to the inner wall of the working plate 5, the upper surface of the adsorption head 22 is fixedly connected to a transition pipe 23, and the transition pipe 23 is connected to the input end of the external gas treatment device through an external hose.

[0040] When the chip smokes, the adsorption head 22 works to absorb the smoke, so that the smoke and odor do not affect the staff, ensuring the health of the staff and the working environment. When the force plate 11 makes a reciprocating linear motion in the vertical direction, the force plate 11 drives the external rod 17 to move synchronously. When the external rod 17 drops, it pushes the side plate 24. At this time, the side plate 24 drives the slide plate 18 and the fixed block 19 to move in the direction of squeezing the return spring 21. When the force plate 11 and the external rod 17 rise and no longer push the side plate 24, , the side plate 24, the slide plate 18 and the fixed block 19 move back under the action of the return spring 21, and the above process is repeated. The side plate 24 performs reciprocating linear motion in the horizontal direction under the thrust of the external rod 17, the fixed block 19, the limit rod 20 and the return spring 21. At this time, the side plate 24 drives the slide plate 18 and the adsorption head 22 to move synchronously, thereby increasing the working range of the adsorption head 22, which can better handle smoke and odor. When the adsorption head 22 is working, the smoke and odor are discharged through the transition pipe 23.

[0041] Embodiment 3: The difference from embodiment 2 is that, by setting the cleaning component, when working, the air bag 26 and the nozzle 27 spray the special cleaning agent to ensure the cleanliness of the working position on the left side of the working plate 5. Figure 1 and Figure 10 As shown:

[0042] A support plate 25 is fixedly connected to the left surface of the working plate 5, and a cleaning assembly is provided on the surface of the support plate 25. The cleaning assembly includes an air bag 26 adhesively connected to the upper surface of the support plate 25. When the cleaning assembly is working, it sprays detergent to the left side of the working plate 5. The cleaning assembly also includes a nozzle 27 fixedly connected to the surface of the air bag 26, and the nozzles 27 are evenly spaced on the surface of the air bag 26. A pressure plate 28 is fixedly connected to the lower surface of the external rod 17, and a feed pipe 29 is fixedly connected to the upper surface of the air bag 26, and a one-way valve 30 is fixedly connected to the surface of the feed pipe 29 and the surface of the nozzle 27.

[0043] When the force plate 11 drives the external rod 17 to make reciprocating linear motion in the vertical direction, the external rod 17 drives the pressure plate 28 to move synchronously, and when the pressure plate 28 descends, the pressure plate 28 squeezes the airbag 26. At this time, the airbag 26 sprays the special cleaning agent through the nozzle 27. When the pressure plate 28 rises, the airbag 26 is not squeezed. At this time, the airbag 26 is expanded by suction through the feed pipe 29. Then, during the working process, when the pressure plate 28 intermittently squeezes the airbag 26, the airbag 26 will intermittently spray the special cleaning agent, which can be used in advance. The workbench 1 and the negative pressure adsorption plate 4 are cleaned to facilitate the subsequent cleaning work of the staff. In the process of the airbag 26 spraying the detergent through the nozzle 27 and inhaling through the feed pipe 29, the one-way valve 30 prevents the detergent from being sprayed out from the feed pipe 29, so that the working direction of the special detergent is from the airbag 26 to the nozzle 27, ensuring the stability of the operation of the airbag 26 and the nozzle 27. At the same time, when the special detergent inside the airbag 26 is consumed, the special detergent can be added to the inside of the airbag 26 through the feed pipe 29.

[0044] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
