Description

Technical Field

[0001] The invention belongs to the field of chip processing and relates to plastic packaging technology, in particular to a chip plastic packaging body placer. Background Art

[0002] Chip encapsulation is the process of encapsulating the exposed chip in materials such as plastic or ceramic, generally using epoxy resin materials, to protect and fix the chip and provide electrical connections; the general steps are: place the encapsulation material in the specified position of the material cake fixture, place the packaged chip inside the material cake fixture, close the mold at the specified temperature, demould, and clean the gate material.

[0003] The reference patent name is: A chip plastic package placer (patent announcement number: CN118493745A). Through the vibration of the vibration frame, the plastic package is pre-loaded into each placement tube. In order to avoid too many plastic packages in the vibration frame and the inability to feed the plastic packages into the placement tubes, a pouring unit can pour a small amount of plastic packages into the vibration frame in batches; through the movement of the vibration frame, the plastic package at the bottom of the placement tube falls into the inside of the material cake clamp, realizing automatic loading of the plastic package.

[0004] However, when implementing the above technical solution, there are the following problems: when the above device is vibrating to place the plastic packaging body into each placement tube, it can only ensure that there is a plastic packaging body inside each placement tube through a specific vibration time, and it is difficult to guarantee the quantity. In addition, during the movement and unloading process of the vibration frame, it cannot be guaranteed that the plastic packaging body continues to enter the placement tube. When the plastic packaging body inside the placement tube is used up, it needs to be put back in after a certain period of time, which relatively prolongs the time required for the overall chip plastic packaging.

[0005] To this end, the present invention provides a chip plastic package placer. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a chip plastic package placer that solves the problem of existing chip plastic package placers being unable to guarantee the number of plastic packages to be sorted, which affects the subsequent uniform delivery of plastic packages at various locations into a cake clamp.

[0007] To achieve the above-mentioned object, according to an embodiment of the first aspect of the present invention, a chip plastic package placer is provided, comprising: a placement table, wherein a blanking mechanism is provided inside the placement table, and the blanking mechanism comprises:

[0008] A plurality of blanking troughs, each of which is provided inside the placement table and has a quantitative component inside;

[0009] The quantitative component includes a towing block slidably arranged inside the placing table. The towing block covers the blanking chute. A pulling spring is fixedly connected between the towing block and the placing table. The placing table is slidably connected with a driving block. A reset spring is fixedly connected between the driving block and the placing table. There is an overlapping area in the projections of the driving block and the towing block.

[0010] A rotating ring is rotatably arranged inside the placing table. The center of the rotating ring and the center of the blanking chute are on the same vertical line. A plurality of arc-shaped blocks are rotatably connected to the surface of the rotating ring. The rotating ring and the driving block are symmetrically arranged with respect to the blanking chute. A driving component is arranged between the rotating ring and the driving block.

[0011] Optionally, the driving component includes a driving gear and an intermediate gear. Both the driving gear and the intermediate gear are rotatably arranged inside the placing table. A transmission component is arranged between the driving gear and the intermediate gear.

[0012] Optionally, a number of passive teeth are fixedly connected to the surface of the driving block. The passive teeth are meshed with the driving gear. A number of driving teeth are fixedly connected to one side of the rotating ring close to the towing block. The driving teeth are meshed with the intermediate gear.

[0013] Optionally, the cross-section of the rotating ring is arc-shaped. The width of the driving teeth is the same as the radius of the rotating ring.

[0014] Optionally, the transmission component includes transmission wheels fixed on the surfaces of the driving gear and the intermediate gear. A transmission belt is cross-connected between the two transmission wheels in a half-cross manner.

[0015] Optionally, a spiral groove is formed inside the arc-shaped block. A number of spiral columns are fixedly connected to the surface of the rotating ring. The spiral columns are adapted to the spiral groove.

[0016] Optionally, a dropping block is slidably connected inside the placing table. A disassembly component is arranged between the dropping block and the towing block.

[0017] Optionally, a number of dropping grooves are formed on the surface of the dropping block. The size of the dropping grooves is larger than that of the towing block. A push-pull spring is fixedly connected between the dropping block and the placing table.

[0018] Optionally, the disassembly component includes a disassembly shaft fixedly arranged on the surface of the dropping block. A disassembly groove is formed on the surface of the towing block. The disassembly shaft is adapted to the disassembly groove.

[0019] Optionally, an arc-shaped groove is formed on the surface of the dropping block. A limiting rod is threadedly connected inside the placing table. The limiting rod is adapted to the arc-shaped groove.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] It includes a towing block, a driving block and a rotating ring. A plurality of arc-shaped blocks are rotatably connected to the surface of the rotating ring. Since the center of the rotating ring and the center of the blanking chute are on the same vertical line, the arc-shaped blocks can rotate above the blanking chute to block the blanking chute or rotate into the blanking chute to assist in blanking. The towing block moves downward under the action of the plastic sealing body. When it moves downward to a certain position, it causes the driving block to move. At this time, the rotating ring is rotated by the driving assembly, thereby changing the position of the arc-shaped blocks, which can prevent other plastic sealing bodies from falling into the blanking chute. Then, after a certain number of plastic sealing bodies enter the blanking chute, the blanking chute will prevent other plastic sealing bodies from falling, which can ensure the number of plastic sealing bodies in a single blanking chute, and thus ensure that there are no missing positions on the surface of the powder cake fixture;

[0022] A dropping block is arranged to slide between the placing table and the powder cake fixture, and a relatively large dropping groove is formed on the surface of the dropping block, and the size of the dropping groove is larger than that of the towing block. A disassembly assembly is arranged between the dropping block and the towing block, so that the towing block can move along with the dropping block. When the dropping groove replaces the original position of the towing block, the plastic sealing body will fall onto the surface of the powder cake fixture along the dropping groove, realizing the placement of the plastic sealing body on the surface of the powder cake fixture; and a push-pull spring is arranged between the dropping block and the placing table, and it will automatically reset without applying force. At this time, the powder cake fixture inside the placing table can be replaced, and a limiting rod and an arc-shaped groove are arranged between the dropping block and the placing table, which can limit the position of the dropping block when not in use to prevent accidental touch from affecting the overall placement process of the plastic sealing body.

[0036] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0037] As Figure 1-8 shown, a chip encapsulation body placer includes a placing table 1, and a blanking mechanism is arranged inside the placing table 1. The blanking mechanism includes:

[0038] It should be noted that a plurality of transparent blocks are arranged on the surface of the placing table, and the transparent blocks are flush with and partially communicate with the blanking chute, so that the number of encapsulation bodies inside the blanking chute can be directly observed;

[0039] A plurality of blanking chutes 21 are all opened inside the placing table 1, and the positions of the blanking chutes 21 correspond to the positions of the holes on the surface of the powder cake fixture; the diameter of the blanking chute 21 is larger than the diameter of the encapsulation body;

[0040] It should be noted that the powder cake fixture and the holes on its surface are the same as the powder cake fixture and the hole structure disclosed in the patent with the title: A chip encapsulation body placer (patent publication number: CN118493745A);

[0041] The cross-section of the blanking chute 21 is in a funnel shape, and a quantitative component is arranged inside each of the blanking chutes 21;

[0042] The quantitative component includes a towing block 22 slidably arranged inside the placing table 1. The towing block 22 covers the blanking chute 21. A pulling spring 23 is fixedly connected between the towing block 22 and the placing table 1. The placing table 1 is slidably connected with a driving block 24. A reset spring 25 is fixedly connected between the driving block 24 and the placing table 1. There is an overlapping area in the projections of the driving block 24 and the towing block 22;

[0043] A rotating ring 26 is rotatably arranged inside the placing table 1. The center of the rotating ring 26 and the center of the blanking chute 21 are on the same vertical line. A plurality of arc-shaped blocks 27 are rotatably connected to the surface of the rotating ring 26; The rotating ring 26 and the driving block 24 are symmetrically arranged relative to the blanking chute 21;

[0044] A driving component is arranged between the rotating ring 26 and the driving block 24;

[0045] In the actual application process of this chip encapsulation body placer, it includes a towing block 22, a driving block 24 and a rotating ring 26. A plurality of arc-shaped blocks 27 are rotatably connected to the surface of the rotating ring 26. Since the center of the rotating ring 26 and the center of the blanking chute 21 are on the same vertical line, the arc-shaped blocks 27 can rotate above the blanking chute 21 to block the blanking chute 21 or rotate into the blanking chute 21 to assist in blanking. The towing block 22 moves downward under the action of the encapsulation body. When it moves downward to a certain position, it prompts the driving block 24 to move. At this time, the rotating ring 26 is rotated through the driving component, and then the position of the arc-shaped blocks 27 is changed, which can prevent other encapsulation bodies from falling into the blanking chute 21. Then, after a certain number of encapsulation bodies enter the blanking chute 21, the blanking chute 21 will prevent other encapsulation bodies from falling, which can ensure the number of encapsulation bodies in a single blanking chute 21, and thus ensure that there are no missing positions on the surface of the powder cake clamp;

[0046] In some specific implementation schemes, the driving component includes a driving gear 31 and an intermediate gear 32. Both the driving gear 31 and the intermediate gear 32 are rotatably arranged inside the placing table 1. A transmission component is arranged between the driving gear 31 and the intermediate gear 32. A number of passive teeth 33 are fixedly connected to the surface of the driving block 24. The passive teeth 33 are meshed with the driving gear 31; A number of driving teeth 34 are fixedly connected to one side of the rotating ring 26 close to the towing block 22. The driving teeth 34 are meshed with the intermediate gear 32. The cross-section of the rotating ring 26 is arc-shaped. The width of the driving teeth 34 is the same as the radius of the rotating ring 26; Through the passive teeth 33, the driving gear 31, the driving teeth 34 and the intermediate gear 32, the movement of the driving block 24 is converted into the rotation of the rotating ring 26, and then the arc-shaped blocks 27 on the surface of the rotating ring 26 can be driven to change positions;

[0047] In a further embodiment, the transmission assembly includes transmission wheels 35 fixed to the surfaces of the driving gear 31 and the intermediate gear 32, and a transmission belt 36 is cross-connected between the two transmission wheels 35 in a half-crossed manner;

[0048] It should be noted that half-crossed transmission refers to a belt drive in which the two axes of the belt pulleys are staggered in space, and the staggered angle is usually 90°;

[0049] Through the transmission wheels 35 and the transmission belt 36 in half-crossed transmission, the intermediate gears 32 and the driving gears 31 at different positions can be driven to rotate synchronously, and then the rotating ring 26 can be driven to move;

[0050] In some specific embodiments, a spiral groove 41 is formed inside the arc-shaped block 27, and a plurality of spiral columns 42 are fixedly connected to the surface of the rotating ring 26, and the spiral columns 42 are adapted to the spiral groove 41; through the spiral columns 42 and the spiral groove 41, when the rotating ring 26 moves, the spiral columns 42 are driven to slide inside the spiral groove 41, and then the spiral groove 41 drives the arc-shaped block 27 to rotate;

[0051] In some specific embodiments, a motor is fixedly connected to the surface of the placement table 1, the motor is electrically connected to an external power source, one end of the output shaft of the motor is fixedly connected to a coupling (not shown in the figure), and the coupling (not shown in the figure) is fixedly connected to a stirring rod; through the stirring rod, the plastic sealing body inside the placement table 1 is directly driven to move and change its position;

[0052] In a further embodiment, a plurality of through grooves are formed on the surface of the placement table 1, and the cross-sections of the through grooves are all fan-shaped; through the through grooves, a sufficient amount of plastic sealing body can be put into the placement table 1, and at the same time, the state of the plastic sealing body inside the placement table 1 can be observed, and the plastic sealing body can be further blocked from scattering to the outside of the placement table 1;

[0053] In some specific embodiments, a control block is slidably connected to the surface of the towing block 22, and the control block is fixedly connected to the pulling spring 23;

[0054] In a further embodiment, a dropping block 51 is slidably connected inside the placement table 1, a disassembly assembly is provided between the dropping block 51 and the towing block 22, a plurality of dropping grooves 52 are formed on the surface of the dropping block 51, the size of the dropping grooves 52 is larger than that of the towing block 22, and a push-pull spring 53 is fixedly connected between the dropping block 51 and the placement table 1; through the dropping block 51 that slides inside the placement table 1, the towing block 22 can be driven to move, and then the plastic sealing body can be guided to fall from inside the dropping grooves 52 onto the surface of the powder cake fixture;

[0055] In a further embodiment, the disassembly component includes a disassembly shaft 54 fixedly arranged on the surface of the dropping block 51. A disassembly groove 55 is formed on the surface of the towing block 22, and the disassembly shaft 54 is adapted to the disassembly groove 55;

[0056] In a further embodiment, an arc-shaped groove 56 is formed on the surface of the dropping block 51. A limiting rod 57 is threadedly connected inside the placing table 1, and the limiting rod 57 is adapted to the arc-shaped groove 56; The presence of the limiting rod 57 can limit the position of the dropping block 51 inside the placing table 1, thereby preventing the dropping block 51 from moving;

[0057] The working principle of the present invention:

[0058] First, pour a sufficient amount of plastic-sealed body into the placing table 1, start the motor, and the motor drives the stirring rod to rotate, causing the plastic-sealed body to fall into the blanking groove 21. The plastic-sealed body contacts the towing block 22 and drives the towing block 22 to move downward. The towing block 22 moves downward until it contacts the driving block 24, and then moves downward again, driving the driving block 24 to move horizontally. This movement causes the driving gear 31 to rotate. The rotation of the driving gear 31 drives the intermediate gear 32 to rotate through the transmission component, drives the rotating ring 26 to move, and causes the arc-shaped block 27 to rotate. The arc-shaped block 27 hinders the subsequent blanking of the blanking groove 21. At this time, the towing block 22 is locked with the control block. Place the powder cake clamp on the surface of the placing table 1, push the control block, drive the towing block 22 to move, and the plastic-sealed body slides down.

[0059] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
