Description

Technical Field

[0001] The invention belongs to the technical field of chip processing, and in particular relates to an integrated circuit chip packaging coating device. Background Art

[0002] Integrated circuits are an indispensable part of electronic devices such as computers, communications, and televisions. Integrated circuit plastic packaging is a technology that protects chips. The plastic packaging process protects the chips from factors such as temperature, humidity, and mechanical impact, ensuring the stability of chip performance and service life. In the integrated circuit plastic packaging process, coating is a very critical step. It can prevent water ingress, enhance structural stability, improve dehumidification capacity, and isolate air and other impurities during the storage, transportation, and use of integrated circuits.

[0003] The existing integrated circuit chip packaging coating device includes a long plate concave rail, a film feeder, a film collector, a film tape, a multi-axis machine tool and an outer cover frame. The outer cover frame is buckled and pressed on the film tape at the outer edge of the hollow circular hole. The outer cover frame moves laterally to control the film tape, assist in the transportation of the film tape, and avoid wrinkles in the film tape. The coordinated design of the unit element and the cutting element achieves a stable cutting effect. The cutting element moves in a circular motion to cut the film tape. The cutting element encounters the unit element during its movement, triggering the deformation of the unit element, and then the cutting element passes through the unit element smoothly. In this way, at most only one unit element does not apply pressure to the film tape at a time, and the cutting element can stably cut the film tape.

[0004] Although the existing device can complete the cutting and stretching operations on the packaging film, thereby effectively avoiding the problem of wrinkles on the packaging film, it ignores a key detail. In the absence of external force, the packaging film covering the chip is difficult to form a stable connection with the chip due to its uneven surface. This instability will directly affect the packaging and coating effects of the chip, and then cause poor packaging or film falling off during the use of the chip.

[0005] Therefore, in view of the above situation, it is urgent to develop an integrated circuit chip packaging coating device to overcome the shortcomings in current practical applications. Summary of the invention

[0006] In view of the shortcomings of the prior art, an object of the embodiments of the present invention is to provide an integrated circuit chip packaging coating device to solve the problems in the above-mentioned background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] An integrated circuit chip packaging film coating device, comprising a device frame, a slide seat is vertically slidably mounted on the device frame, a film coating frame is fixed on one side of the slide seat, reels for winding and unwinding a packaging film are mounted on both sides of the device frame, two reels are distributed on both sides of the film coating frame, the packaging film is located directly below the film coating frame, a conveyor belt perpendicular to the packaging film is arranged below the packaging film, a chip is placed on the conveyor belt, a film coating disc is arranged between the film coating frame and the packaging film, the film coating disc is rotatably mounted on the film coating frame through a connecting shaft, and further comprising:

[0009] A rotating mechanism, which is mounted on the laminating frame and fixedly connected to the connecting shaft;

[0010] An intermittent regulating mechanism, the intermittent regulating mechanism comprising a linkage component and a regulating component, one end of the linkage component is mounted on the laminating frame and is located outside the laminating disk, and the other end of the linkage component is mounted on the laminating disk and connected to the regulating component mounted on the laminating disk;

[0033] A connecting sleeve rotatably mounted on the coating disc and concentric with the connecting shaft, wherein a worm gear is fixed to the outside of the connecting sleeve;

[0034] a disc fixed to the outside of the connecting sleeve; and

[0035] The connecting rods are circumferentially distributed on the disc, the distribution number and distribution position of the connecting rods are consistent with the distribution number and distribution position of the guide groove, and one end of the connecting rod is rotatably connected to the pressing assembly installed in the guide groove.

[0036] As a further technical solution of the present invention, the pressing assembly includes:

[0048] The rotating mechanism can drive the film coating disk to rotate forward or reversely. The intermittent regulating mechanism can drive the guiding mechanism to work continuously in the forward direction or intermittently in the reverse direction by means of forward rotation or reverse rotation. When the guiding mechanism drives the film coating mechanism to work continuously in the forward direction, the film coating mechanism can continuously move outward, so that the pressing component and the cutting component thereon can adaptively move to the edge end of the chip. When the guiding mechanism drives the film coating mechanism to work intermittently in the reverse direction, the cutting component firstly packages the packaging film at the edge end of the chip by reversing, and the pressing component squeezes the packaging film at the edge end of the chip. Then, the cutting component deflects in the reverse direction and separates from the packaging film, so as to avoid the cutting component from damaging the chip or the packaging film on the chip during the inward or outward movement, thereby ensuring the packaging quality and packaging efficiency of the chip. The pressing component can effectively and fully press the packaging film on the trajectory from the edge end of the chip to its center position by means of intermittent inward movement and continuous rotation, thereby ensuring the connection stability between the packaging film and the chip, thereby improving the packaging quality and packaging efficiency of the chip, thereby improving the working efficiency and practicality of the device, reducing the packaging time of the chip, and reducing the cost of chip packaging.

DETAILED DESCRIPTION

[0059] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0060] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0061] like Figures 1 to 8As shown, as an embodiment of the present invention, an integrated circuit chip packaging laminating device is provided, comprising a device frame 100, on which a slide 110 is vertically slidably mounted, a laminating frame 400 is fixed to one side of the slide 110, the slide 110 can move vertically on the device frame 100, thereby changing the vertical height of the laminating frame 400, and reels 200 for winding and unwinding a packaging film 210 are mounted on both sides of the device frame 100, and the two reels 200 are distributed on the laminating frame 400. 00, and the packaging film 210 is located directly below the film laminating frame 400, a conveyor belt 300 perpendicular to the packaging film 210 is arranged below the packaging film 210, a chip is placed on the conveyor belt 300, and the conveyor belt 300 is used to intermittently convey the chip to the bottom of the packaging film 210 so that the packaging film 210 performs automatic packaging processing on it, a film laminating plate 600 is arranged between the film laminating frame 400 and the packaging film 210, and the film laminating plate 600 is rotatably mounted on the film laminating frame 400 through a connecting shaft 610, and further includes:

[0062] A rotating mechanism 500, wherein the rotating mechanism 500 is mounted on the laminating frame 400 and is fixedly connected to the connecting shaft 610;

[0063] An intermittent regulating mechanism 700, comprising a linkage assembly 710 and a regulating assembly 720, wherein one end of the linkage assembly 710 is mounted on the laminating frame 400 and is located outside the laminating disk 600, and the other end of the linkage assembly 710 is mounted on the laminating disk 600 and connected to the regulating assembly 720 mounted on the laminating disk 600;

[0064] A guide mechanism 800, which is circumferentially distributed on the coating disc 600 and slidably cooperates with the guide grooves 620 circumferentially opened on the coating disc 600, and one end of the guide mechanism 800 is fixedly connected to the regulating component 720;

[0065] The laminating mechanism 900 includes a pressing component 910 and a cutting component 920. The pressing component 910 is mounted on the guide mechanism 800 and is located at the bottom of the laminating disk 600. One end of the cutting component 920 is mounted on the pressing component 910, and the other end of the cutting component 920 is connected to the bottom of the laminating disk 600.

[0066] The slide 110 can drive the laminating disk 600, the rotating mechanism 500, the intermittent regulating mechanism 700, the guiding mechanism 800 and the laminating mechanism 900 to move vertically synchronously through the laminating frame 400. The laminating mechanism 900 can not only press the packaging film 210 onto the chip on the conveyor belt 300 by vertical movement, so that the packaging film 210 can perform laminating treatment on the unpackaged chip, but also release the packaging film 210, so that the packaging film 210 is separated from the packaged chip, so that the packaged chip can enter the next process with the conveyor belt 300.

[0067] When it is necessary to expand the pressing range of the pressing component 910 on the packaging film 210, the rotating mechanism 500 drives the connecting shaft 610 to rotate forward, and the connecting shaft 610 drives the coating disc 600 to rotate. The coating disc 600 also drives one end of the linkage component 710, the regulating component 720, the guide mechanism 800 and the coating mechanism 900 to rotate synchronously. One end of the linkage component 710 can drive the other end to rotate continuously by rotating and cooperating with the coating frame 400. The other end of the linkage component 710 drives the regulating component 720 to rotate continuously. The regulating component 720 drives the pressing component 910 and the cutting component 920 to move continuously outward through the guide mechanism 800. The cutting component 920 deflects during the process of continuous outward movement.

[0068] When the pressing component 910 and the cutting component 920 move to the desired position, the cutting end of the cutting component 920 contacts the packaging film 210, and the pressing component 910 contacts the edge end of the chip and squeezes the packaging film 210 above the chip. At this time, the rotating mechanism 500 drives the connecting shaft 610 to rotate in the opposite direction, and the connecting shaft 610 drives the film coating disk 600 to rotate in the opposite direction. The film coating disk 600 also drives one end of the linkage component 710, the regulating component 720, the guide mechanism 800 and the film coating mechanism 900 to rotate in the opposite direction synchronously. The cutting component 920 in the rotating state can cut the packaging film 210 located outside the edge end of the chip, and the pressing component 910 in the rotating state covers the packaging film 210 at the edge end of the chip.

[0069] One end of the linkage component 710 can drive the other end thereof to rotate in the opposite direction through the film laminating frame 400, and the other end of the linkage component 710 drives the regulating component 720 to rotate intermittently. The regulating component 720 drives the pressing component 910 and the cutting component 920 to move inward intermittently through the guiding mechanism 800, so that the cutting component 920 deflects in the opposite direction and separates from the packaging film 210, thereby preventing the cutting component 920 from damaging the chip or the packaging film 210 on the chip during the inward or outward movement, thereby ensuring the packaging quality and packaging efficiency of the chip. The pressing component 910 can effectively and fully press the packaging film 210 on the trajectory from the edge end of the chip to its center position by intermittent inward movement and continuous rotation, thereby ensuring the connection stability between the packaging film 210 and the chip, thereby improving the packaging quality and packaging efficiency of the chip, thereby improving the working efficiency and practicality of the device, reducing the packaging time of the chip, and reducing the cost of chip packaging.

[0070] like Figure 3 and Figure 4 As shown, as a preferred embodiment of the present invention, the rotating mechanism 500 includes a motor 510, a main shaft 520 and a transmission member 530, the motor 510 is fixed on the coating frame 400, the main shaft 520 is fixed on the output end of the motor 510, and the main shaft 520 is fixedly connected to the connecting shaft 610 through the transmission member 530.

[0071] In this embodiment, the motor 510 drives the main shaft 520 to rotate, and the main shaft 520 drives the connecting shaft 610 to rotate through the transmission member 530, thereby driving the coating disk 600 to rotate forward or reverse, so that the coating mechanism 900 can complete the cutting and pressing of the packaging film 210, and then complete the automatic packaging of the chip, thereby improving the working efficiency and practicality of the device, reducing the chip packaging time, and reducing the chip packaging cost.

[0072] In a preferred embodiment, the transmission member 530 preferably adopts a transmission structure composed of a synchronous belt and a synchronous wheel.

[0073] like Figures 3 to 7As shown, as a preferred embodiment of the present invention, the linkage assembly 710 includes an annular internal gear 711, a bevel gear 712, a rotating shaft A713, a universal joint 714, a rotating shaft B715, a bracket A716, a bracket B717, a strip slide 718 and a Z-shaped slide 719, the annular internal gear 711 is fixed on the laminating frame 400 and is located on the outside of the laminating disk 600, and the annular internal gear 711 is concentric with the laminating disk 600, the bevel gear 712 is meshed with the annular internal gear 711, and the bevel gear 712 is fixed on the rotating shaft A713. On one side of the axis A713, the rotating shaft A713 is rotatably mounted on the coating disk 600, and one end of the rotating shaft A713 is connected to the rotating shaft B715 through a universal joint 714, and both ends of the rotating shaft B715 are rotatably mounted on the coating disk 600 through brackets A716 and B717 respectively, and one end of the rotating shaft B715 is provided with a strip slide groove 718, and the end of the strip slide groove 718 is provided with a Z-shaped slide groove 719 connected thereto, and the strip slide groove 718 and the Z-shaped slide groove 719 intermittently slide with the regulating component 720.

[0074] In this embodiment, the connecting shaft 610 drives the coating disk 600 to rotate, and the coating disk 600 drives the bevel gear 712 thereon to rotate. Since the annular internal gear 711 and the coating frame 400 are stationary, the bevel gear 712 in the rotating state can drive the rotating shaft A713 to rotate by meshing with the annular internal gear 711 in the stationary state. The rotating shaft A713 drives the rotating shaft B715 to rotate through the universal joint 714. The rotating shaft B715 drives the regulating component 720 to work through the strip slide groove 718 and the Z-shaped slide groove 719, so that the regulating component 720 can drive the coating mechanism 900 to move outward or inward through the guide mechanism 800. The coating mechanism 900 can effectively and fully press the packaging film 210 on the trajectory from the edge end of the chip to its center position, thereby ensuring the connection stability between the packaging film 210 and the chip, thereby improving the packaging quality and packaging efficiency of the chip.

[0075] In a preferred embodiment, the Z-shaped slide groove 719 is perpendicular to the strip slide groove 718, the Z-shaped slide groove 719 is opened in the circumferential direction of the rotating shaft B715, and the strip slide groove 718 is opened in the axial direction of the rotating shaft B715.

[0076] like Figures 3 to 7As shown in FIG. 1 , as a preferred embodiment of the present invention, the regulating assembly 720 includes a hollow worm 721, a worm wheel 722, a spring A723, a bar column 724, a movable part 725 and a guide sleeve 726. The hollow worm 721 is sleeved on the outside of the rotating shaft B715. The hollow worm 721 is meshed with the worm wheel 722 fixed on the guide mechanism 800. One end of the hollow worm 721 is equipped with a bar column 724. The other end of the hollow worm 721 is connected to the guide mechanism 800 by a spring. A723 is connected to the bracket A716, and the strip column 724 intermittently cooperates with the strip slide groove 718 and the Z-shaped slide groove 719. A movable part 725 is installed at one end of the strip column 724. The outer wall of the movable part 725 intermittently slides with the guide sleeve 726 fixed on the bracket B717. The guide sleeve 726, the hollow worm 721 and the rotating shaft B715 are all concentric, and the end of the guide sleeve 726 that slides with the outer wall of the movable part 725 is set as an inclined end.

[0077] In the present embodiment, when it is necessary to expand the pressing range of the pressing component 910 on the packaging film 210, the strip column 724 is located at the connection between the strip slide groove 718 and the Z-shaped slide groove 719, the motor 510 drives the main shaft 520 to rotate forward, the main shaft 520 drives the connecting shaft 610 to rotate forward through the transmission member 530, the connecting shaft 610 drives the coating disk 600 to rotate forward, and the coating disk 600 drives the bevel gear 712 thereon to rotate. Since the annular internal gear 711 and the coating frame 400 are stationary, the bevel gear 712 in the rotating state can drive the rotating shaft A713 to rotate by meshing with the stationary annular internal gear 711, and the rotating shaft A713 drives the rotating shaft B715 to rotate by the universal joint 714;

[0078] At this time, the rotating shaft B715 drives the Z-shaped slide groove 719 and the strip slide groove 718 to rotate at the same time, so that the strip column 724 cooperates with the Z-shaped slide groove 719, and the Z-shaped slide groove 719 drives the strip column 724 to rotate continuously. The strip column 724 drives the hollow worm 721 and the movable part 725 to rotate continuously at the same time. The movable part 725 does not slide with the guide sleeve 726 during the rotation process. The hollow worm 721 drives the worm wheel 722 to rotate continuously. The worm wheel 722 can drive the pressing assembly 910 and the cutting assembly 920 to move outward continuously through the guide mechanism 800. The cutting assembly 920 deflects during the continuous outward movement.

[0079] When the pressing component 910 and the cutting component 920 move to the required position, the cutting end of the cutting component 920 conflicts with the packaging film 210, and the pressing component 910 conflicts with the edge end of the chip and squeezes the packaging film 210 above the chip. At this time, the motor 510 drives the connecting shaft 610 to rotate in the opposite direction, and the connecting shaft 610 drives the coating disk 600 to rotate in the opposite direction, so that the cutting component 920 in the rotating state can cut the packaging film 210 located outside the edge end of the chip, and the pressing component 910 in the rotating state presses the packaging film 210 at the edge end of the chip. At the same time, the rotating shaft A713 and the rotating shaft B715 rotate in the opposite direction, and the rotating shaft B715 drives the strip slide 718 and the Z-shaped slide 719 to rotate in the opposite direction. The slide groove 719 can drive the bar column 724 located therein to the connection point between the bar column 724 and the bar slide groove 718 by reverse rotation, so that the bar column 724 will not cooperate with the Z-shaped slide groove 719 in the state of reverse rotation, and the spring A723 drives the hollow worm 721 to move by its own elastic force, and the hollow worm 721 drives the bar column 724 and the movable member 725 to move in the direction close to the guide sleeve 726, so that the movable member 725 slides and cooperates with the inclined end of the guide sleeve 726, and the movable member 725 can drive the bar column 724 to reciprocate in the bar slide groove 718 by cooperating with the guide sleeve 726 and the spring A723, and the bar column 724 can drive the hollow worm 721 to reciprocate;

[0080] When the hollow worm 721 in the self-rotating state moves in the direction close to the spring A723, the hollow worm 721 cannot drive the worm wheel 722 to perform normal rotational movement. The thread surface on the hollow worm 721 that rotates and moves synchronously can be regarded as a circular thread surface. Although it rotates in the tooth surface of the worm wheel 722, it does not drive it to rotate, and the two do not have a meshing relationship; when the hollow worm 721 in the self-rotating state moves in the direction away from the spring A723, the thread surface on the hollow worm 721 and the tooth surface on the worm wheel 722 resume the meshing relationship, so that the hollow worm 721 drives the worm wheel 722 to rotate normally, thereby realizing the intermittent self-rotation of the worm wheel 722;

[0081] The worm gear 722 drives the guide mechanism 800 to work intermittently, and the guide mechanism 800 drives the pressing component 910 and the cutting component 920 to move inward intermittently, so that the cutting component 920 deflects in the opposite direction and separates from the packaging film 210, thereby preventing the cutting component 920 from damaging the chip or the packaging film 210 on the chip during the inward or outward movement, thereby ensuring the packaging quality and packaging efficiency of the chip. The pressing component 910 can effectively and fully press the packaging film 210 on the trajectory from the edge of the chip to its center position by intermittent inward movement and continuous rotation, thereby ensuring the connection stability between the packaging film 210 and the chip, thereby improving the packaging quality and packaging efficiency of the chip, thereby improving the working efficiency and practicality of the device, reducing the packaging time of the chip, and reducing the cost of chip packaging.

[0082] In a preferred embodiment, the movable member 725 preferably adopts a roller structure.

[0083] like Figures 3 to 5 As shown, as a preferred embodiment of the present invention, the guide mechanism 800 includes a connecting sleeve 810, a disc 820 and a connecting rod 830. The connecting sleeve 810 is rotatably mounted on the coating disc 600 and is concentric with the connecting shaft 610. A worm gear 722 and a disc 820 are respectively fixed to the outside of the connecting sleeve 810. The disc 820 is circumferentially distributed with connecting rods 830. The distribution number and distribution position of the connecting rods 830 are consistent with the distribution number and distribution position of the guide groove 620. One end of the connecting rod 830 is rotatably connected to a pressure-coating assembly 910 installed in the guide groove 620.

[0084] In this embodiment, the worm gear 722 drives the connecting sleeve 810 to rotate, and the connecting sleeve 810 drives the disc 820 to rotate. The disc 820 can drive the pressing component 910 to move in the guide groove 620 by rotating and cooperating with the connecting rod 830, so that the pressing component 910 and the cutting component 920 thereon can move outward or inward, thereby realizing rapid packaging of the chip and improving the packaging quality and packaging efficiency of the chip.

[0085] In a preferred embodiment, the circular disc 820 is concentric with the coating disc 600, and the connecting sleeve 810, the connecting shaft 610, the circular disc 820 and the worm gear 722 are all concentric.

[0086] like Figure 2 , Figure 3 and Figure 8As shown, as a preferred embodiment of the present invention, the pressing assembly 910 includes a slider 911, a slide column 912, a U-shaped frame 913, a pressure wheel 914 and a spring B915, the slider 911 is slidably installed in the guide groove 620, the slider 911 is vertically slidably installed with a slide column 912, and a cutting assembly 920 is installed on one side of the slider 911, the bottom of the slide column 912 is fixed with a U-shaped frame 913, the top of the U-shaped frame 913 is connected to the bottom of the slider 911 through a spring B915, and the bottom of the U-shaped clamp is installed with a pressure wheel 914.

[0087] In this embodiment, the coating frame 400 can drive the pressing component 910 to rotate forward or reverse, and the disc 820 can drive the slider 911 to move in the guide groove 620 by rotating on its own and cooperating with the connecting rod 830. The slider 911 can drive the pressure wheel 914 to move outward or inward through the sliding column 912 and the U-shaped frame 913. The pressure wheel 914 in the forward or reverse state can effectively and fully press the packaging film 210 on the trajectory from the edge end of the chip to its center position by moving outward or inward, thereby ensuring the connection stability between the packaging film 210 and the chip, thereby improving the packaging quality and packaging efficiency of the chip.

[0088] like Figure 2 , Figure 3 and Figure 8 As shown, as a preferred embodiment of the present invention, the cutting assembly 920 includes a spur gear 921, a mounting shaft 922, a cutting knife 923, a rack 924 and a mounting frame 925, the mounting shaft 922 is rotatably mounted on one side of the slider 911, the spur gear 921 and the cutting knife 923 are respectively fixed on the mounting shaft 922, the bottom of the spur gear 921 is meshed with the rack 924 fixed on the mounting frame 925, the rack 924 is distributed at the edge position of the bottom of the coating tray 600, and the mounting frame 925 is fixed on the bottom of the coating tray 600.

[0089] In this embodiment, when the slider 911 drives the mounting shaft 922, the cutting knife 923 and the spur gear 921 to move outward, the cutting end of the cutting knife 923 is close to the bottom of the film coating disk 600. When the spur gear 921 moves to a position meshing with the rack 924, the rack 924 drives the spur gear 921 to deflect. The spur gear 921 drives the cutting knife 923 to deflect through the mounting shaft 922, so that the cutting end of the cutting knife 923 rotates toward the direction close to the packaging film 210. When the slider 911 moves to a desired position, the cutting end of the cutting knife 923 is in conflict with the packaging film 210 and is located outside the edge of the chip.

[0090] When the slider 911 drives the mounting shaft 922, the cutting knife 923 and the spur gear 921 to move inward, the cutting knife 923 first cuts the packaging film 210 outside the edge of the chip by reversing. At the same time, before the cutting end of the cutting knife 923 moves to the edge of the chip, the rack 924 drives the spur gear 921 to deflect in the opposite direction, so that the cutting end of the cutting knife 923 deflects in the opposite direction and moves away from the chip and the packaging film 210 thereon, thereby preventing the cutting knife 923 from damaging the chip or the packaging film 210 on the chip, thereby ensuring the packaging quality and packaging efficiency of the chip and improving the coating efficiency and coating quality of the device.

[0091] In a preferred embodiment, the position of the mounting frame 925 at the bottom of the coating disk 600 is adjustable and parallel to the guide groove 620, so that the meshing time of the rack 924 and the spur gear 921 can be changed at any time, so that the coating mechanism 900 can effectively and fully package chips of different diameters, thereby improving the practicality and convenience of the device.

[0092] The working principle of the present invention is:

[0093] The slide 110 can drive the laminating disk 600, the rotating mechanism 500, the intermittent regulating mechanism 700, the guiding mechanism 800 and the laminating mechanism 900 to move vertically synchronously through the laminating frame 400. The laminating mechanism 900 can not only press the packaging film 210 onto the chip on the conveyor belt 300 by vertical movement, so that the packaging film 210 can perform laminating treatment on the unpackaged chip, but also release the packaging film 210, so that the packaging film 210 is separated from the packaged chip, so that the packaged chip can enter the next process with the conveyor belt 300.

[0094] When it is necessary to expand the pressing range of the pressing component 910 on the packaging film 210, the strip column 724 is located at the connection between the strip slide groove 718 and the Z-shaped slide groove 719, the motor 510 drives the main shaft 520 to rotate forward, the main shaft 520 drives the connecting shaft 610 to rotate forward through the transmission member 530, the connecting shaft 610 drives the coating disk 600 to rotate forward, and the coating disk 600 drives the bevel gear 712 thereon to rotate. Since the annular internal gear 711 and the coating frame 400 are stationary, the bevel gear 712 in the rotating state can drive the rotating shaft A713 to rotate by meshing with the stationary annular internal gear 711, and the rotating shaft A713 drives the rotating shaft B715 to rotate by the universal joint 714;

[0095] At this time, the rotating shaft B715 drives the Z-shaped slide groove 719 and the strip slide groove 718 to rotate at the same time, so that the strip column 724 cooperates with the Z-shaped slide groove 719, and the Z-shaped slide groove 719 drives the strip column 724 to rotate continuously. The strip column 724 drives the hollow worm 721 and the movable part 725 to rotate continuously at the same time, and the movable part 725 does not slide and cooperate with the guide sleeve 726 during the rotation process. The hollow worm 721 drives the worm wheel 722 to rotate continuously, and the worm wheel 722 drives the connecting sleeve 810 to rotate, and the connecting sleeve 810 drives the disc 820 to rotate. The disc 820 can drive the slider 911 to move in the guide groove 620 by rotating and cooperating with the connecting rod 830. The slider 911 can slide The column 912 and the U-shaped frame 913 drive the pressing wheel 914 and the cutting knife 923 to continuously move outward. When the slider 911 drives the mounting shaft 922, the cutting knife 923 and the spur gear 921 to move outward, the cutting end of the cutting knife 923 is close to the bottom of the film coating disk 600. When the spur gear 921 moves to a position meshing with the rack 924, the rack 924 drives the spur gear 921 to deflect. The spur gear 921 drives the cutting knife 923 to deflect through the mounting shaft 922, so that the cutting end of the cutting knife 923 rotates in a direction close to the packaging film 210. When the slider 911 moves to a desired position, the cutting end of the cutting knife 923 is in conflict with the packaging film 210 and is located outside the edge of the chip.

[0096] When the pressing assembly 910 and the cutting assembly 920 move to the desired positions, the motor 510 drives the connecting shaft 610 to rotate in the opposite direction, and the connecting shaft 610 drives the film coating disk 600 to rotate in the opposite direction, so that the cutting knife 923 first cuts the packaging film 210 outside the edge of the chip in a reverse manner, and before the cutting end of the cutting knife 923 moves to the edge of the chip, the rack 924 drives the spur gear 921 to deflect in the opposite direction, so that the cutting end of the cutting knife 923 deflects in the opposite direction and moves away from the chip and the packaging film 210 thereon, so as to prevent the cutting knife 923 from damaging the chip or the packaging film 210 thereon, and the rotating pressing wheel 914 presses the packaging film 210 at the edge of the chip;

[0097] At the same time, the rotating shaft A713 and the rotating shaft B715 rotate in the opposite direction, and the rotating shaft B715 drives the strip slide groove 718 and the Z-shaped slide groove 719 to rotate in the opposite direction. The Z-shaped slide groove 719 can drive the strip column 724 located therein to the connection point between it and the strip slide groove 718 by means of reverse rotation, so that the strip column 724 will not cooperate with the Z-shaped slide groove 719 in the state of reverse rotation, and the spring A723 drives the hollow worm 721 to move by its own elastic force, and the hollow worm 721 drives the strip column 724 and the movable part 725 to move in the direction close to the guide sleeve 726, so that the movable part 725 slides and cooperates with the inclined end of the guide sleeve 726, and the movable part 725 can drive the strip column 724 to reciprocate in the strip slide groove 718 by means of cooperating with the guide sleeve 726 and the spring A723, and the strip column 724 can drive the hollow worm 721 to reciprocate;

[0098] When the hollow worm 721 in the self-rotating state moves in the direction close to the spring A723, the hollow worm 721 cannot drive the worm wheel 722 to perform normal rotational movement. The thread surface on the hollow worm 721 that rotates and moves synchronously can be regarded as a circular thread surface. Although it rotates in the tooth surface of the worm wheel 722, it does not drive it to rotate, and the two do not have a meshing relationship; when the hollow worm 721 in the self-rotating state moves in the direction away from the spring A723, the thread surface on the hollow worm 721 and the tooth surface on the worm wheel 722 resume the meshing relationship, so that the hollow worm 721 drives the worm wheel 722 to rotate normally, thereby realizing the intermittent self-rotation of the worm wheel 722;

[0099] The worm gear 722 drives the guide mechanism 800 to work intermittently, and the guide mechanism 800 drives the pressing wheel 914 to move inward intermittently through the slider 911, so that the pressing wheel 914 can effectively and fully press the packaging film 210 on the trajectory from the edge end of the chip to its center position by moving inward intermittently and rotating continuously;

[0100] The above is the working principle of the integrated circuit chip packaging coating device.

[0101] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
