Description

Technical Field

[0001] The 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, the integrated circuit has the functions of analog signal processing and digital signal processing. It also has the functions of equipment control, system control and coordination, and is 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 contacted 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-mentioned 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 to insert the integrated circuit chip into the inner side of the seal cavity seat and 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 detection fails, smoke and fire occur, the odor will be inhaled by the human body, which will affect the health of the operator. The chip detection device in the above application does not have the function of odor absorption during use, and has low safety, which will affect the operating environment of the staff.

[0007] Preferably, the lower connecting rods are symmetrically distributed about the center of the auxiliary plate, and the ends of the lower connecting rods are fixedly connected with partitions, and the surfaces of the lower connecting rods are slidably provided with force-bearing plates.

[0008] Preferably, a connecting spring is fixedly connected to the upper surface of the partition, and the other side of the connecting spring is fixedly connected to the lower surface of the force-bearing plate, and an upper connecting plate is fixedly connected to the upper surface of the force-bearing plate, the front view of the upper connecting plate is an inverted "L" structure, and a knocking rod is fixedly connected to the lower surface of the upper connecting plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: adopting a new structural design, during the detection process, when the chip smokes or catches fire, the sound reminder component can be set to make the sound piece intermittently sound, which plays a role of prompting and warning, and a smoke and dust adsorption component is also set, so that the smoke and odor can be sucked away by the adsorption head, ensuring the safety of the detection environment and protecting the health of the staff. In addition, a cleaning component is also set 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) When the automatic loading integrated circuit packaging inspection equipment is in operation, the chip to be inspected is placed in a material box above the workbench, and the chip is clamped and placed on a negative pressure adsorption plate by a robotic arm. Automatic loading is achieved by the robotic arm, and then appearance inspection is achieved by a camera, and power-on inspection is completed by an 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 make 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 clicker, and then the clicker 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 of the automatic loading integrated circuit packaging detection equipment smokes, the suction head will work to absorb the smoke, so that the smoke and odor will not affect the staff, thus ensuring the health of the staff 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, 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) In 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, and the airbag sprays a special cleaning agent through the nozzle. When the pressure plate rises, the airbag is not squeezed, and the airbag expands by suction through the feeding pipe. Then, during the working process, when the pressure plate intermittently squeezes the airbag, the airbag will intermittently spray a special cleaning agent, so that the workbench and the negative pressure adsorption plate can be cleaned in advance, which is convenient for the staff's subsequent cleaning work.

[0021] Furthermore, during the process of the airbag spraying cleaning agent through the nozzle and inhaling air through the feed pipe, the one-way valve prevents the cleaning agent from spraying out from the feed pipe, so that the working direction of the special cleaning agent is from the airbag to the nozzle, thereby 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, the special cleaning agent can be added to the inside of the airbag through the feed pipe.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work 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 role of warning and reminder, 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 robot 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 arranged on the right side of the work plate 5, 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 a cam 9, and the lower surface of the auxiliary plate 6 is fixedly connected to a lower connecting rod 12, and the upper surface of the auxiliary plate 6 is fixedly connected to a sound plate 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 a partition 13, and the surface of the lower connecting rod 12 is slidably provided with a force plate 11.

[0036] A connecting spring 14 is fixedly connected to the upper surface of the partition 13, and the other side of the connecting spring 14 is fixedly connected to the lower surface of the force-bearing plate 11, and an upper connecting plate 15 is fixedly connected to the upper surface of the force-bearing plate 11. 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 arranged 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, the smoke and dust in the detection process will be sucked away.

[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 mechanical arm 2. Automatic loading is achieved through the mechanical 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 to drive 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. Under the action of the connecting spring 14 and the lower connecting rod 12, it descends to its 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 serves to limit the moving distance of the force-bearing plate 11 and ensures stability.

[0038] Embodiment 2: Different from Embodiment 1, by setting the smoke adsorption component, when working, the adsorption head 22 can absorb the smoke and odor generated by the chip abnormality, ensuring the safety of 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 attached to the 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 plate 18 at equal intervals, and the surface of the slide plate 18 is fixedly connected with a fixed block 19, the inner wall of the working plate 5 is fixedly connected with a limit rod 20, and the limit rod 20 and the fixed block 19 are movably connected, the surface of the fixed block 19 is fixedly connected with 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 with 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 suction 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 descends, 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 reset 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 makes 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: Different from Embodiment 2, the cleaning component is provided, and when working, the airbag 26 and the nozzle 27 spray a special cleaning agent to ensure the cleanliness of the working position on the left side of the working plate 5. Figure 1 and Fig.10 As shown:

[0042] A support plate 25 is fixedly connected to the left surface of the working plate 5, and a cleaning component is arranged on the surface of the support plate 25. The cleaning component includes an air bag 26 bonded to the upper surface of the support plate 25. When the cleaning component is working, cleaning agent is sprayed to the left side of the working plate 5. The cleaning component 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, 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, and the airbag 26 sprays the special cleaning agent through the nozzle 27, and when the pressure plate 28 rises, the airbag 26 is not squeezed, and the airbag 26 is inflated by suction through the feed pipe 29, and 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 cleaning agent through the nozzle 27 and sucking air through the feeding pipe 29, the one-way valve 30 prevents the cleaning agent from being sprayed out from the feeding pipe 29, so that the working direction of the special cleaning agent is from the airbag 26 to the nozzle 27, thereby ensuring the working stability of the airbag 26 and the nozzle 27. At the same time, when the special cleaning agent inside the airbag 26 is consumed, the special cleaning agent can be added to the inside of the airbag 26 through the feeding 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.
