Description

Technical Field

[0001] The present invention relates to the technical field of chip packaging, and more particularly to a chip packaging structure and a cover plate packaging mechanism used therein. Background Art

[0002] Chips are an important part of the development of modern science and technology and are widely used in electronics, communications, medical treatment, automobiles, home appliances, security and other fields. The expansion and deepening of artificial intelligence, the Internet of Things, virtual reality and other fields in the future will inevitably bring higher and more complex demands for chip performance, so the innovation and upgrading of chip technology is an inevitable trend; as the core component of electronic products, the stability and reliability of the chip function play a vital role in the performance of the product, so the chip needs to be packaged to avoid the chip from mechanical damage, chemical corrosion and other external annular influences, thereby extending its service life and improving the stability and reliability of the product.

[0003] The traditional chip packaging structure uses plastic packaging, which completely seals the chip in plastic. The chip cannot sense the external temperature, humidity, gas, and air pressure, so the sensing device needs to be prepared separately. Moreover, plastic is an insulator and is not conductive, so it cannot achieve electrostatic shielding, so electrostatic shielding needs to be processed separately, such as adding an electromagnetic shielding metal shell to the overall structure of the chip package. The existing electromagnetic shielding metal shell is threadedly connected to the shielding base plate by bolts during installation.

[0004] However, the electromagnetic shielding metal shell is threadedly connected to the shielding bottom plate by bolts. The bolts are prone to loosening or rusting after long-term use, which makes the electromagnetic sealing of the overall structure insufficient and fails to achieve a good electromagnetic shielding effect.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0035] In one embodiment, a first conductive connector 5 corresponding to each first chip and a second conductive connector 6 corresponding to each second chip and third chip are embedded in the substrate 1. The first chip is connected to the conductive layer 2 at the bottom of the substrate 1 through the corresponding first conductive connector 5, and the second chip and the third chip are connected to the conductive layer 2 at the bottom of the substrate 1 through the corresponding second conductive connector 6.

[0036] In one embodiment, the packaging structure further includes a rectangular basket-shaped metal cover plate 31, and the upper surface of the substrate 1 is provided with a frame-shaped second groove 4 that matches the bottom opening of the metal cover plate 31. The second groove 4 effectively limits the metal cover plate 31, thereby preventing the metal cover plate 31 from being offset due to the fluidity of the adhesive during installation.

[0037] like Figure 2-6 As shown, a metal cover plate packaging mechanism is arranged on one side of the conveyor belt, including a base 7, a stepper motor 8 is arranged in the base 7, a first transmission rod 9 is fixedly connected to the output end of the stepper motor 8, the first transmission rod 9 is provided with N hollow positioning blocks 10, two hydraulic rods 11 are arranged on the side wall of each positioning block 10 away from the first transmission rod 9, the two hydraulic rods 11 located on the same positioning block 10 are located on the same vertical line, a second transmission rod 12 is fixedly connected to the free end of the upper hydraulic rod 11, a third transmission rod 14 is fixedly connected to the free end of the lower hydraulic rod 11, each second transmission rod 12 is installed with a plurality of first clamping parts, each second transmission rod 12 is respectively installed with a second clamping part corresponding to each first clamping part, N is greater than or equal to 1; a micro hydraulic pump is arranged in the positioning block 10, and the two hydraulic rods 11 located on the same positioning block 10 are respectively connected and have a hollow tube, and the two hollow tubes are connected through the micro hydraulic pump.

[0038] In one embodiment, each positioning block 10 is fixedly connected to a first positioning plate 15, and each first positioning plate 15 is fixedly connected to a second positioning plate 16 at one end away from the positioning block 10, and the second transmission rod 12 and the third transmission rod 14 are both provided with corresponding second positioning plates 16 at one end away from the hydraulic rod 11.

[0039] In one embodiment, a limiting rod 17 corresponding to each first positioning plate 15 is fixedly connected to the first transmission rod 9, and a sliding rod 18 is fixedly connected to each first positioning plate 15. The end of each sliding rod 18 away from the positioning rod passes through the corresponding limiting rod 17 and is fixedly connected to a baffle plate. A first spring 19 is sleeved on each sliding rod 18, and the two ends of the first spring 19 are respectively in contact with the baffle plate and the first positioning plate 15; an annular air bag is fixedly connected to the bottom surface of each limiting rod 17, and each air bag is sleeved on the outer surface of the corresponding sliding rod 18. A micro air pump 13 is installed on each limiting rod 17, and each micro air pump 13 is connected to the corresponding air bag through a hollow hose.

[0040] In one embodiment, a plurality of storage portions are installed on the base 7, and a plurality of metal cover plates 31 with mountings are arranged from top to bottom in the storage portions.

[0041] In one embodiment, a storage pool 25 is further provided on the base 7 , and the storage pool 25 is filled with adhesive. A motor 27 is installed on the storage pool 25 , and a roller brush 26 is fixedly connected to the output end of the motor 27 .

[0042] As an optional embodiment of the present invention, the number of the positioning block 10 and the corresponding limiting rod 17 is preferably 3, and at this time, the three limiting rods 17 are equidistantly distributed around the first transmission rod 9. At the same time, the storage portion and the storage pool 25 are respectively arranged corresponding to the length direction of the limiting rod 17 located above the base 7.

[0043] In one embodiment, the present invention further comprises a tray for loading the substrate 1 , the upper surface of the tray is recessed with a plurality of storage spaces adapted to the shape of the substrate 1 , and the storage spaces on the tray are arranged in a straight line to facilitate packaging of the metal cover 31 .

[0044] In one embodiment, the tray is in the shape of a cuboid.

[0045] In one embodiment, the number of storage spaces on the tray is the same as the number of first clamping portions on each third transmission rod 14 , that is, the number of metal cover plates 31 captured by the cover plate packaging mechanism each time.

[0046] In the present invention, the first clamping part and the corresponding second clamping part form a group. When the metal cover plate 31 is grasped, the distance between the two adjacent groups is adapted to the distance between the two adjacent storage spaces on the pallet. At the same time, a rectangular placement space is provided on both sides of each storage space. When the cover plate is packaged, the first clamping part and the second clamping part will extend into the placement space, so as to ensure that when the metal cover plate 31 is installed, the first clamping part and the second clamping part will not collide with the pallet and cause a jam. The rectangular placement space allows the first clamping part and the second clamping part to move smoothly to both sides without hindrance after the cover plate is packaged.

[0047] The three limit rods 17 are respectively labeled as limit rod No. 1 17, limit rod No. 2 17 and limit rod No. 3 17. When the installation mechanism is put into use, the stepper motor 8 is first started, and the limit rod No. 1 17 rotates to the top of the storage part. Then the micro air pump 13 on the limit rod No. 1 17 starts to work and inflates the inside of the airbag connected thereto, thereby increasing the distance between the limit rod No. 1 17 and the first positioning plate 15 corresponding thereto, thereby achieving the downward movement effect of the first clamping part and the second clamping part. The micro air pump 13 stops working after a preset time. At this time, the free ends of the first clamping part and the second clamping part are just aligned with the two side walls of the metal cover plate 31. At this time, the micro hydraulic pump starts to work, which transmits the hydraulic oil in the upper hydraulic rod 11 to the lower hydraulic rod 11. At this time, the micro hydraulic pump 13 stops working after a preset time. A clamping part and a corresponding second clamping part gradually approach each other. When the hydraulic oil in the upper hydraulic rod 11 completely enters the lower hydraulic rod 11, the first clamping part and the second clamping part firmly clamp the metal cover plate 31. Then the micro air pump 13 continues to work to discharge the gas in the annular airbag 20. At the same time, under the action of the spring, the clamped metal cover plate 31 moves up with the first positioning plate 15. After a preset time, the micro airbag stops working, and the stepper motor 8 rotates counterclockwise 120 degrees. At this time, the No. 1 limit rod 17 clamping the metal cover plate 31 moves to the top of the storage pool 25, and at the same time, the No. 2 limit rod 17 moves to the top of the storage part.

[0048] Then, the components on the second limiting rod 17 repeat the operation of the first limiting rod 17 above the storage part, and the micro air pump 13 on the first limiting rod 17 works again. When the micro airbag is inflated, the surface of the opening of the metal cover plate 31 contacts the roller brush 26, and the adhesive in the storage pool 25 is applied to its surface through the roller brush 26. It should be noted that when the installation mechanism starts working, the motor 27 starts working together and continuously drives the roller brush 26 to rotate, so that the adhesive in the storage pool 25 is covered on the surface of the roller brush 26, so as to facilitate the application of the adhesive to the metal cover plate 31. After a preset time, the micro air pump 13 works again to deflate the annular airbag 20, so that the metal cover plate 31 coated with the adhesive follows the first positioning plate 15 to restore the initial state, and at this time, the second limiting plate 22 also completes the clamping work of the metal cover plate 31 in the storage part and removes it from the storage part.

[0049] Then, the stepper motor 8 drives the first transmission rod 9 to reverse 120 degrees again after a preset time. At this time, the first limit rod 17 drives the metal cover plate 31 coated with adhesive to move to the top of the conveyor belt, and then the metal cover plate 31 is installed. At the same time, the second limit rod 17 drives the metal cover plate 31 clamped from the storage part to move to the top of the storage pool 25, and repeats the above adhesive coating work; the third limit rod 17 moves to the top of the storage part, and repeats the above clamping work of the metal cover plate 31.

[0050] When the metal cover 31 is installed, the micro air pump 13 inflates the wake-up airbag again, so that the first clamping part and the corresponding second clamping part drive the metal cover 31 to move toward the tray position. After a preset time, the micro air pump 13 completes the inflation of the annular airbag 20. At this time, the metal cover 31 is completely pressed into the second groove 4 on the substrate 1. At this time, the micro hydraulic pump in the positioning block 10 corresponding to the No. 1 limit rod 17 starts working again, and it transfers the hydraulic oil in the lower hydraulic rod 11 to the upper hydraulic rod 11. At this time, the first clamping part and the corresponding second clamping part move to both sides respectively based on the clamped metal cover 31, so as to cancel the clamping effect of the metal cover 31. Then, the micro air pump 13 deflates the annular airbag 20, and the first clamping part and the second clamping part rise at a uniform speed until they return to their original state.

[0051] At this time, the metal cover plate 31 corresponding to the No. 2 limit rod 17 has completed the application of the adhesive, and at the same time, the No. 3 limit rod 17 has completed the clamping work of the metal cover plate 31. Finally, the stepper motor 8 rotates 120 degrees counterclockwise for the third time, and the metal cover plate 31 corresponding to the No. 2 limit rod 17 moves to the position above the conveyor belt, and then repeats the installation steps of the metal cover plate 31 when the No. 1 limit rod 17 moves to the top of the conveyor belt; the No. 3 limit rod 17 drives the clamped metal cover plate 31 to move to the top of the storage pool 25, and applies the above-mentioned adhesive, and the No. 1 limit rod 17 moves to the top of the storage part again, and clamps the metal cover plate 31.

[0052] It should be noted that when N is equal to 3, with the No. 1 limit rod 17 as the reference, the stepper motor 8 drives the first transmission rod 9 to rotate 120 degrees each time and then stops, and continues to rotate after a preset time. The preset time is the period from when the annular airbag 20 starts to inflate to when it is completely deflated.

[0053] In order to further ensure the accuracy of the metal cover 31 during installation, a first electric telescopic rod and a second electric telescopic rod are additionally provided on the base 7. The first electric telescopic rod is parallel to the conveyor belt, and the second electric telescopic rod is parallel to the first transmission rod 9. An L-shaped first partition is fixedly connected to the end of the first electric telescopic rod away from the base 7, and a second partition is fixedly connected to the end of the second electric telescopic rod away from the base 7. When the first electric telescopic rod is opened to the maximum extension position, the first partition is located above the conveyor belt. At this time, the corresponding first clamping part and the second clamping part on a certain limit rod 17 correspond to the position of the first partition. At this time, the opening of each metal cover 31 that has been coated with adhesive and moved above the conveyor belt corresponds to the second groove 4 on the base plate 1 in each storage space on the tray.

[0054] In the present invention, the conveyor belt is a step-by-step conveyor belt, that is, it conveys forward a preset distance after a preset time. When installing the metal cover plate 31, first, the first electric telescopic rod is extended. At this time, the first partition extends onto the conveyor belt, and then the step-by-step conveyor belt conveys the tray loaded with the substrate 1 to the first partition, and the side wall of the tray contacts the side wall of the first partition. At this time, the staff fine-tunes the tray so that the long side wall of the tray contacts the long arm of the first partition, and the short side wall of the tray contacts the short arm of the first partition. At this time, the installation preparation of the metal cover plate 31 is completed.

[0055] While the first electric telescopic rod is working, the second electric telescopic rod also starts working. After the second electric telescopic rod is opened to the maximum extension position, the second partition moves to the height of the positioning block 10, thereby assisting the stepper motor 8 in further determining the rotation angle of the first transmission rod 9, thereby avoiding the error of the stepper motor 8 itself.

[0056] After the cover plate is packaged, the first electric telescopic rod and the second electric telescopic rod are retracted, thereby canceling the limit on the support plate and the positioning block 10, so as to facilitate the subsequent work.

[0057] It should be noted that the stepper motor 8 and the stepper conveyor belt are both devices well known to those skilled in the art in the prior art, and both are devices capable of realizing high-precision positioning and transmission functions. Therefore, the specific internal structure and working principle thereof will not be further described in the present invention.

[0058] In one embodiment, an electric heating plate is provided in the wall thickness of the storage pool 25, and the electric heating plate ensures that the adhesive in the storage pool 25 does not solidify over time.

[0059] In one embodiment, a slider is integrally formed on the surface of each positioning block 10 on the side opposite to the first transmission rod 9, and a slide groove 21 is provided on the surface of the first transmission rod 9 at a position corresponding to each slider. The slider is slidably connected in the corresponding slide groove 21. Through the mutual cooperation between the slide groove 21 and the slider, the corresponding positioning block 10 and the components connected to the positioning block 10 are limited, and then the cover plate that needs to be packaged is limited, thereby avoiding the possibility of deviation during the installation process.

[0060] In one embodiment, the first clamping part includes two first clamping units 28 arranged opposite to each other, and the surfaces on opposite sides of the two first clamping units 28 are provided with fourth grooves adapted to the surface of the third transmission rod 14; the second clamping part includes two second clamping units 29 arranged opposite to each other, and the surfaces on opposite sides of the two second clamping units 29 are provided with fifth grooves adapted to the surface of the second transmission rod 12. The detachable first clamping unit 28 and the second clamping unit 29 allow the staff to more conveniently disassemble, maintain and replace the first clamping part and the second clamping part, and also can adjust the positions of the first clamping part and the second clamping part, so as to be suitable for the installation of metal cover plates 31 of different specifications.

[0061] In one embodiment, a third groove is further provided on the surface of the opposite side of the two second clamping units 29, and the third groove is arranged with the central axis of the third transmission rod 14, and the diameter of the third groove is greater than the diameter of the second transmission rod 12. In this way, the friction between the second clamping unit 29 and the second transmission rod 12 is avoided, and the working efficiency of the second clamping part is improved.

[0062] In one embodiment, a groove is provided at the bottom of each first clamping portion and the corresponding side wall of the corresponding second clamping portion, and the longitudinal length of the groove is shorter than the height of the cover plate, thereby increasing the contact area with the cover plate, thereby improving the stability when grasping the cover plate, and the groove also serves to limit the cover plate.

[0063] In one embodiment, each groove is provided with a flexible material, such as rubber, polytetrafluoroethylene, etc.

[0064] In one embodiment, each storage portion includes a rectangular storage plate and a limiting plate 22 installed at the four top corners of the storage plate. The four limiting plates 22 on each storage plate enclose a rectangle that matches the cover plate; the tops of the opposite side walls of the two limiting plates 22 arranged diagonally are integrally formed with a protrusion; each storage plate is provided with a push plate 23 that matches the rectangle enclosed by the limiting plates 22, and the push plate 23 is connected to the storage plate through a plurality of second springs 24. The staff arranges a plurality of metal cover plates 31 from top to bottom and pushes them into the storage portion. At this time, the spring pushes the arranged metal cover plates 31 to the upper end position of the storage portion. In order to ensure that the metal cover plates 31 will not be pushed out under the action of the second springs 24, a protrusion is added to the limiting plate 22 to achieve the limiting effect of the metal cover plates 31 in the storage portion.

[0065] In one embodiment, the number of the receiving portions may be determined according to the number of the first clamping portions, and each receiving portion is provided corresponding to a first clamping portion and a corresponding second clamping portion.

[0066] In one embodiment, the distance between the two limiting plates 22 on the left side of the storage plate is matched with the first clamping portion; the distance between the two limiting plates 22 on the right side of the storage plate is matched with the second clamping portion.

[0067] In one embodiment, the storage plates are arranged in a straight line and are set parallel to the limit rod 17 above them. At the same time, two adjacent storage plates are connected by a connecting plate, and the two ends of the connecting plate are respectively fixed to the two storage plates. Threaded holes of the same specifications are opened on each connecting plate and on the upper surface of the base 7. The connecting plate and the base 7 are fixedly connected by bolts or screws to fix the storage part.

[0068] In one embodiment, the second positioning plates 16 corresponding to the No. 1 limiting rod 17 , the No. 2 limiting rod 17 , and the No. 3 limiting rod 17 are respectively the No. 1 second positioning plate 16 , the No. 2 second positioning plate 16 , and the No. 3 second positioning plate 16 .

[0069] A first controller and a battery electrically connected to each other are installed at the fixed connection between each limit rod 17 and the first transmission rod 9, and each micro air pump 13 is respectively connected to the first controller and the battery; a No. 1 magnetic induction sensor, a No. 2 magnetic induction sensor and a No. 3 magnetic induction sensor connected to the first controller are respectively installed at the bottom of the No. 1 second positioning plate 16, the No. 2 second positioning plate 16 and the No. 3 second positioning plate 16, and a magnetic induction sensor connected to the first controller are respectively installed, and a magnetic component, such as a magnet, is provided on the storage portion and the storage pool 25 at a position located on the same vertical line as the magnetic induction device; an L-shaped connecting rod 30 is also provided on one side of the base 7, the long arm of the connecting rod 30 is fixed to the base 7, and the short arm is vertically arranged upward, and a magnetic part is also provided on the short arm of the connecting rod 30.

[0070] Take the No. 1 limit plate 22 as an example: when the No. 1 limit plate 22 moves to the top of the storage part, the first magnetic induction sensor senses the magnetic parts and transmits the signal to the first controller, and the first controller then issues a command to the micro air pump 13 on the No. 1 limit plate 22 and controls it to start working. When the No. 1 limit plate 22 moves to the top of the storage pool 25 or the conveyor belt, the first magnetic induction sensor senses the magnetic parts and transmits the signal to the first controller, and the start and stop of the micro air pump 13 is controlled by the first controller.

[0071] In one embodiment, the first controller is also connected to the stepper motor 8 to control the start and stop of the stepper motor 8 .

[0072] In one embodiment, a second controller is further provided on the base 7 and is connected to the first electric telescopic rod and the second electric telescopic rod respectively, so as to control the start and stop of the first electric telescopic rod and the second electric telescopic rod.

[0073] It should be noted that in the present invention, the stepper motor 8 and the first electric telescopic rod and the second electric telescopic rod are all powered by plugging in the prior art.
