Description

Technical Field

[0001] The present invention relates to the technical field of electronic component packaging, and in particular to a convenient packaging device for electronic components. Background Art

[0002] Packaging is the process of assembling integrated circuits into final chip products. Simply put, it is to place the bare integrated circuit chips produced by the foundry on a supporting substrate, lead out the pins, and then fix the package into a whole. The entire packaging process involves a lot of mechanical equipment, and the last step is injection molding packaging, in which resin material is injected into the cavity, the resin material surrounds the electronic components, and then the cavity is sealed. The packaging is completed after the resin material cools and solidifies.

[0003] Currently, the cavity for packaging electronic components is mostly composed of a box body and a cover body, thereby enclosing the circuit die and resin material inside. The box body and the cover body are fixed together by a number of clips. However, some problems have been found in use:

[0004] 1. When assembling the box body and the cover, since the position of the fasteners is fixed, whether it is mechanical assembly of the box body and the cover or manual assembly, it is necessary to identify the position of the fasteners and then assemble the box body and the cover. This increases the process and reduces the assembly efficiency. If multiple fasteners are arranged in a mirror image on the box body and the cover, although it is more convenient during assembly, it is inconvenient to open it later, which is not conducive to random inspection, and the fasteners are easy to break;

[0005] 2. Existing packaging cavities are often made of plastic. When the box body and the cover body are combined, the plastic will produce a certain deformation. Under this deformation, the resin inside the box body may overflow when too much resin is injected, which is not conducive to controlling the product quality of electronic components. Summary of the Invention

[0006] In order to overcome the above technical problems, an object of the present invention is to provide a convenient packaging device for electronic components.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] A convenient packaging device for electronic components, comprising a cover and a box body spliced ​​together, wherein the inner walls of the four sides of the box body cavity are each provided with a lower clamping member, and the bottom surface of the cover body is provided with an upper clamping member that snaps into engagement with the lower clamping member;

[0009] The bottom surface of the cover body and the top surface of the edge of the box body are respectively provided with a sealing strip and a liquid collecting groove, the sealing strip is fixedly engaged with the liquid collecting groove, and the groove depth of the liquid collecting groove is greater than the thickness of the sealing strip;

[0010] The middle portion of the cover body is further provided with a flap movably connected thereto.

[0011] Furthermore, four clamping feet are placed on the bottom surface of the cavity of the box body, and the clamping feet are in an L-shaped structure.

[0012] Furthermore, the sealing strip and the liquid collecting tank are both closed and continuous structures.

[0013] Furthermore, the lower clamp is a right-angled triangle structure that is narrow at the top and wide at the bottom, with its inclined surface facing outward. The cross-section of the upper clamp is a plate-like structure inclined downward, and the inclined surface of the lower clamp is parallel to the upper clamp. The upper end of the upper clamp is also obliquely provided with a reinforcement connecting the upper clamp and the bottom surface of the cover body, and the lower end of the upper clamp is also provided with a hook extending toward the lower clamp.

[0014] Furthermore, the inclined surface of the lower clamping member is provided with a plurality of wavy strips at intervals along its inclined direction.

[0015] Furthermore, a rectangular through hole is provided in the middle of the cover body, and two flip plates that rotate to open in opposite directions are mirror-imaged in the rectangular through hole. Fixed blocks are provided in the middle of the two inner walls opposite to each other in the rectangular through hole, and limiting grooves are provided on the bottom surfaces of the flip plates at the positions corresponding to the fixed blocks.

[0016] Furthermore, when the flap is in a closed state, the top surface of the flap and the top surface of the cover are located in the same plane.

[0017] Furthermore, slots are provided at the joints of the top surfaces of the two flaps.

[0018] Furthermore, the two limiting grooves on the same side of the two flaps are connected to each other, and the size of the fixing block is comparable to that of the two limiting grooves on the same side.

[0019] Beneficial effects of the present invention:

[0020] 1. The present invention provides mutually cooperating fasteners on the four side walls of the box body and the cover body, and when pressed, the pressing feedback of the wavy strips prompts whether it is installed in place, without having to distinguish the position of the fasteners, which makes assembly convenient and efficient.

[0021] 2. By adding a sealing strip and a liquid collecting groove, the resin that overflows from the box body cavity during the snap assembly process enters the liquid collecting groove and does not overflow to the outside. At the same time, the sealing strip seals the liquid collecting groove, which not only plays a role in assisting the snap connection and fixing of the box body and the cover, but also effectively prevents resin from overflowing.

[0022] 3. The openable flap is conducive to subsequent spot checks, and when the flap is in the storage state, it is integrated and natural, making it easy to take out. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 any creative efforts shall fall within the scope of protection of the present invention.

[0031] Example 1:

[0032] like Figure 1-3 As shown, a convenient packaging device for electronic components includes a cover body 2 and a box body 1 spliced ​​together from top to bottom. The box body 1 is a rectangular structure with a cavity in the middle of the top surface. Four clamping feet 11 are placed on the bottom surface of the cavity of the box body 1. The clamping feet 11 are L-shaped structures. The four clamping feet 11 form a rectangle for limiting the electronic components placed in the clamping feet 11.

[0033] like Figure 3 and Figure 4As shown, the inner walls of the four sides of the cavity of the box body 1 are provided with lower clamps 13, and the bottom surface of the cover body 2 is provided with an upper clamp 21 that is snap-fitted with the lower clamp 13. The lower clamp 13 is a right-angled triangle structure that is narrow at the top and wide at the bottom, with its inclined surface facing outward, and the inclined surface of the lower clamp 13 is also spaced apart along its inclined direction with multiple wavy strips 14. The cross-section of the upper clamp 21 is a plate-like structure inclined downward, and the inclined surface of the lower clamp 13 is parallel to the upper clamp 21. The upper end of the upper clamp 21 is also obliquely provided with a reinforcement 211 connecting the upper clamp 21 and the bottom surface of the cover body 2. The reinforcement 211 can enhance the strength of the upper clamp 21 to prevent it from breaking during the buckling process. The lower end of the upper clamp 21 is also provided with a hook 212 extending toward the lower clamp 13.

[0034] According to the technical solution in the above paragraph, when the cover body 2 and the box body 1 are buckled, as the cover body 2 is pressed down, the hook 212 at the lower end of the upper clamp 21 first contacts the wavy strip 14, and emits corresponding sounds and touches during the contact and downward pressing process, prompting the speed of assembly and splicing of the box body 1 and the cover body 2. When the hook 212 moves to the lowest end of the lower clamp 13, the hook 212 is clamped and fixed to the bottom end of the lower clamp 13. At this time, the touch and sound will be louder, prompting that the buckle is installed in place. Since the four side walls of the box body 1 and the cover body 2 are provided with mutually cooperating buckles, there is no need to distinguish the buckle positions, and the assembly is convenient and efficient.

[0035] like Figure 1-3 As shown, the bottom surface of the cover body 2 and the top surface of the edge of the box body 1 are respectively provided with a sealing strip 22 and a liquid collecting groove 12, and the sealing strip 22 is clamped and fixed with the liquid collecting groove 12, and the groove depth of the liquid collecting groove 12 is greater than the thickness of the sealing strip 22. When the upper clamp 21 and the lower clamp 13 are gradually clamped, since the lower clamp 13 extends into the cavity of the box body 1, when the resin in the cavity is relatively full, this causes the resin in the cavity to overflow, and the overflowed resin overflows from the top surface of the edge of the box body 1. When passing through the liquid collecting groove 12, the resin enters the liquid collecting groove 12 and is collected. After the upper clamp 21 and the lower clamp 13 are clamped and fixed, the sealing strip 22 is clamped with the opening of the liquid collecting groove 12. On the one hand, it plays a role in assisting the clamping and fixing of the box body 1 and the cover body 2, and on the other hand, it can also effectively prevent the resin from overflowing from the liquid collecting groove 12.

[0036] In this embodiment, the sealing strip 22 and the liquid collecting tank 12 are both closed and continuous structures, and the sealing effect is good.

[0037] like Figure 3 and Figure 5As shown, a rectangular through hole is provided in the middle of the cover body 2, and two flip plates 23 that rotate to open in opposite directions are mirror-imaged in the rectangular through hole. Fixed blocks 25 are provided in the middle of the two inner walls opposite to each other in the rectangular through hole, and limiting grooves 26 are provided on the bottom surfaces of the flip plates 23 corresponding to the positions of the fixed blocks 25. When the flip plates 23 are in the closed state, the top surfaces of the flip plates 23 and the top surfaces of the cover body 2 are located in the same plane. Since the two limiting grooves 26 on the same side of the two flip plates 23 are connected to each other, the size of the fixed block 25 is comparable to the size of the two limiting grooves 26 on the same side, that is, one fixed block 25 can simultaneously limit and support the two flip plates 23, which is a clever and concise design.

[0038] In this embodiment, a slot 24 is provided at the joint of the top surface of the two flaps 23. When the flaps 23 need to be opened for random inspection, the slot 24 is pressed and the flaps 23 are flipped over. The two flaps 23 are flipped 90° towards each other to open. The size of the two flaps 23 is larger than the size of the electronic components fixed in the cavity of the box body 1. The openable flap 23 is conducive to subsequent random inspections, and when the flaps 23 are in the storage state, they are integrated, natural, and easy to take out.

[0039] Example 2:

[0040] The convenient packaging device for electronic components is basically the same as that of the first embodiment, except that, compared with the first embodiment, the flap 23 is slidably connected to the cover body 2, and the flap 23 is an integrated structure, which is arranged in the middle of the cover body 2. The cover body 2 is a U-shaped structure, and the flap 23 can be inserted into or removed from the cover body 2 as a whole. Correspondingly, the sealing strip 22 will be disconnected at the flap 23.
