Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation fins, in particular to a heat dissipation fin and pin chip assembly device. Background Art

[0002] In the semiconductor packaging process, the assembly of heat sink fins and pinned chips is a key step in improving heat dissipation. From the perspective of device structure, the semiconductor packaging process can be subdivided into chip level, package level, and printed circuit level. At the chip level, the outermost layer of the chip is metallized, leaving the electrodes free for lead wires. The package level mainly refers to connecting the leads of the chip electrodes to the substrate or lead frame and sealing them. The printed circuit board level involves attaching devices such as QFP or BGA to the printed circuit board. In terms of heat dissipation, heat sink fins play a vital role. The working principle of a fin heat sink is to transfer heat from the chip to the fins through heat conduction, and then the fins transfer the heat to the surrounding air through convection.

[0003] In the current assembly process of heat sink fins and chip bodies, precise installation and positioning of the fins remains a technical challenge. Since the fins must be tightly integrated with the chip body to ensure efficient heat conduction, the fins must be installed with impeccable precision. Any deviation in the position of the fins during movement can lead to inaccurate mounting holes, often requiring manual adjustment or repositioning. This not only increases production line operational complexity but also reduces efficiency. Therefore, we propose a device for assembling heat sink fins and pinned chips. Summary of the Invention

[0033] By adopting the above technical solution, the precise coordination of the first moving mechanism 3 and the second moving mechanism 5 realizes the rapid and accurate transportation of the chip body 32 and the heat dissipating fins 53. Both moving mechanisms adopt advanced driving technology and positioning algorithms, which can ensure that they can maintain a stable motion trajectory and a high degree of positioning accuracy in a complex production environment.

[0035] By adopting the above technical solution, the chip body 32 is evenly stacked inside the first movable table 31. This arrangement not only facilitates subsequent automated processing, but also effectively utilizes space and improves production efficiency. The first electric push rod 34 drives the cutting knife 35 to cut the pins of the chip body 32 at a stable speed and force through the precise control of its telescopic end, which not only ensures the accuracy and consistency of the pin cutting, but also avoids errors and safety hazards caused by manual operation.

The upper end surface of the connecting seat 44 is fixedly connected to a transmission motor 441. The output end of the transmission motor 441 passes through the upper end surface of the connecting seat 44 and is fixedly connected. There is a threaded screw 442, and the end of the threaded screw 442 is fixedly connected to the first bearing frame 443 inside the connecting seat 44, and the end of the threaded screw 442 is rotatably sleeved with the threaded screw 442 through a bearing. The inside of the connecting seat 44 is slidably connected to the second support frame 45, and the side of the second support frame 45 close to the mounting plate 42 is fixedly connected to a threaded sleeve 451 threadedly sleeved with the threaded screw 442, and the inside of the second support frame 45 is fixedly connected to a thread locking machine 46, and the outer side wall of the thread locking end of the thread locking machine 46 is fixedly connected to a pneumatic clamp 47 for clamping the chip body 32.

[0037] By adopting the above technical solution, the auxiliary frame 41 serves as the basic support structure of the locking mechanism 4, which is fixedly connected to the upper end surface of the workbench 1, ensuring the stability and reliability of the entire locking process. The locking mechanism 4 realizes the precise positioning and flexible driving of the connecting seat 44 and the key components installed thereon, such as the transmission motor 441 and the threaded screw 442, which not only improves the response speed and positioning accuracy of the locking mechanism 4, but also ensures the coordinated operation between the various components during the locking process, further improving the locking efficiency.

[0038] See also Figure 1 - Figure 8 The second moving mechanism 5 includes a fixed platform 51 fixedly connected to the upper end surface of the workbench 1 and located on one side of the locking mechanism 4. The fixed platform 51 is fixedly connected to a third electric push rod 511 on the side away from the locking mechanism 4. The telescopic end of the third electric push rod 511 is fixedly connected to a side plate 512. The end of the side plate 512 is fixedly connected to a push plate 513 for pushing the heat dissipation fins 53.

The upper end surface of the workbench 1 is fixedly connected to a vertical plate 56 at one side of the fixed platform 51. The side of the vertical plate 56 close to the fixed platform 51 is fixedly connected to a fourth electric push rod 561. The telescopic end of the fourth electric push rod 561 is fixedly connected to a forward plate 562 for pushing the heat dissipation fins 53.

[0039] With the above technical solution, the fixed platform 51 serves as the basic support of the second moving mechanism 5, which is firmly fixed to the upper end surface of the workbench 1, providing a stable platform for the subsequent transportation of the heat dissipating fins 53. Through the carefully designed third electric push rod 511, the second moving mechanism 5 realizes the precise pushing of the heat dissipating fins 53. The telescopic end of the third electric push rod 511 is fixedly connected to the side plate 512, and the push plate 513 on the side plate 512 directly acts on the heat dissipating fin 53, pushing it to slide along the upper end surface of the fixed platform 51. It is not only simple in structure and easy to control, but also ensures the heat dissipation. To ensure the stability and accuracy of the heat fins 53 during transportation, the stop block 514 is fixedly connected to the upper end surface of the fixed platform 51, forming a relative position with the push plate 513, which can provide effective support and positioning for the heat dissipating fins 53 when they are pushed, preventing them from shifting or tilting. The slide plate 515 is fixedly connected to the side of the fixed platform 51 away from the fixed seat 36, providing a smooth channel for the sliding of the heat dissipating fins 53. When the heat dissipating fins 53 are pushed to the specified position, the slide plate 515 can guide them to smoothly transition to the next process, ensuring the continuity and smoothness of the entire transportation process.

At the same time, the internal interconnected design of the second movable platform 52 and the fixed platform 51 enables the heat dissipating fins 53 to flow seamlessly between the two platforms, further improving the continuity and efficiency of the entire assembly process. Through the carefully designed monitoring platform 54, the operator can monitor the transportation status and installation progress of the heat dissipating fins 53 in real time, and promptly discover and deal with potential problems. The visual sensor 55 is connected to the controller 2 through electrical signals, and can collect image information of the heat dissipating fins 53 in real time and perform accurate analysis and processing. By comparing the actual hole position of the heat dissipating fin 53 with the preset standard, the visual sensor 55 can accurately determine whether the heat dissipating fin 53 meets the installation requirements, thereby avoiding assembly failure caused by inaccurate hole position. The model of the visual sensor 55 can be MV-SC2004EM-06S-WBN-Mini.

The guide rod 732 symmetrically slidably sleeved inside it provides stable support and guidance for the fixed plate 733 and its auxiliary components, so that the fixed plate 733 and the electric clamp 75 thereon can be flexibly adjusted in the vertical direction to adapt to heat dissipation fins 53 of different thicknesses and sizes. This design not only improves the clamping accuracy of the heat dissipation fins 53, but also ensures its stability during the assembly process. The movable clamp 751 slides symmetrically inside the electric clamp 75 and can be adaptively adjusted according to the shape and size of the heat dissipation fins 53, thereby achieving tight clamping of the heat dissipation fins 53, which not only improves the stability of the heat dissipation fins 53 during the assembly process, but also reduces the failure rate caused by unstable clamping. The battery compartment 752 is connected to the electric clamp 75 through a wire, which can continuously provide it with stable power support. At the same time, the detachable design of the battery compartment 752 allows the operator to easily replace the battery to ensure the continuous working ability of the electric clamp 75 during long-term operation.

The inner top end of the gear frame 82 is rotatably sleeved with the first gear 821 through a bearing. The first gear 821 is coaxially connected to the first synchronous wheel 812. The inner side wall of the gear frame 82 is fixedly connected to the limiting plate 84. The side of the limiting plate 84 away from the gear frame 82 is rotatably sleeved with the second gear 822 that meshes with the first gear 821 through a bearing. The outer side wall of the limiting plate 84 is fixedly connected to the clamping frame 83 that is rotatably sleeved with the fixed plate 733.

[0049] With the above technical solution, the positioning plate 81 serves as the basic framework of the transmission mechanism 8. The rotational sleeve connection between the positioning plate 81 and the drive rod 741 via the bearing ensures that the drive rod 741 can stably drive the positioning plate 81 and its auxiliary components to rotate together during rotation. This not only improves the overall structural strength of the transmission mechanism 8, but also ensures the accuracy and stability of the rotation. The rotation of the drive rod 741 drives the second synchronous wheel 813 to rotate together, and then drives the first synchronous wheel 812 to rotate through the transmission effect of the synchronous belt 814. This not only achieves efficient power transmission but also ensures the synchronization and coordination of the rotation. The first gear 821 is coaxially connected to the first synchronous wheel 812 to ensure that the rotation between them is consistent. The meshing transmission of the second gear 822 and the first gear 821 achieves precise control of the rotation speed and direction.

[0050] See also Figure 11 、 Figure 12 and Figure 13 The transmission mechanism 8 also includes a second bearing frame 85 fixedly connected to the outer wall of one of the movable clamping jaws 751, the second bearing frame 85 is slidably connected to the limit plate 84, and the opposite side of the two movable clamping jaws 751 is rotatably sleeved with a clamping plate 861 through a bearing. The inner side wall of the second bearing frame 85 is rotatably sleeved with a spline shaft 86 through a bearing, and the spline shaft 86 is fixedly connected to the outer wall of one of the clamping plates 861. The outer side wall of the spline shaft 86 is slidably sleeved with a second sprocket 824, and the end of the second gear 822 is coaxially fixedly connected to the first sprocket 823. The outer sides of the first sprocket 823 and the second sprocket 824 are The wall is sleeved with a chain 825, the lower end face of the second synchronous wheel 813 is fixedly connected with an upper gear disc 873 rotatably sleeved with the drive rod 741, the upper end face of the fixed plate 733 is fixedly connected with a lower gear disc 874, the outer wall of the drive rod 741 is slidably sleeved with a two-way gear disc 872 at the position corresponding to the spline groove 742, the upper end face of the fixed plate 733 is symmetrically fixedly connected with the seventh electric push rod 87, the telescopic end of the seventh electric push rod 87 is fixedly connected with a sleeve frame 871, and the sleeve frame 871 is rotatably sleeved on the outer wall of the two-way gear disc 872, and the two-way gear disc 872 is engaged with the upper gear disc 873 or the lower gear disc 874 for transmission.

[0051] With the above technical solution, the introduction of the second bearing frame 85 provides a stable support for the sliding connection between the movable clamping claw 751 and the limiting plate 84, so that the movable clamping claw 751 can be more flexible and stable when clamping the heat dissipating fin 53. At the same time, it also provides a reliable connection point for the subsequent transmission mechanism. Through the sliding connection between the second bearing frame 85 and the limiting plate 84, the movable clamping claw 751 can move with the rotation of the clamping frame 83, thereby achieving accurate clamping and positioning of the heat dissipating fin 53. The clamping plate 861 is rotatably connected to the movable clamping claw 751 through the bearing, so that the clamping plate 861 can flexibly move with the opening and closing of the movable clamping claw 751. The spline shaft 86 is fixedly connected to the outer wall of the spline plate 861 and is rotatably sleeved through the inner wall of the second bearing frame 85, ensuring the stability and accuracy of the spline plate 861 during the clamping process. The rotation of the second gear 822 can drive the first sprocket 823 to rotate together, and then drive the second sprocket 824 to rotate through the transmission effect of the chain 825, which not only realizes the efficient transmission of power, but also ensures the synchronization and coordination of the rotation action. At the same time, since the second sprocket 824 is slidably sleeved with the spline shaft 86, it can adjust its position as the spline shaft 86 moves, thereby achieving precise control of the spline plate 861 and the heat dissipation fins 53.

[0052] Regarding the assembly of the heat dissipation fins 53 and the chip body 32: the chip body 32 and the heat dissipation fins 53 are moved by the first movable platform 31 and the second movable platform 52 respectively. When the pins of the chip body 32 move to the area of ​​the first support frame 33, the telescopic end of the first electric push rod 34 will drive the cutting knife 35 to move downward to cut off the excessively long pins of the chip body 32. When it moves to the inside of the collection rack 37, it will be located above the push rack 39. At this time, the telescopic end of the second electric push rod 38 drives the push rack 39 to move. Then the telescopic end of the hydraulic push rod 43 drives the connecting seat 44 to move. Since the telescopic end of the second electric push rod 38 drives the push frame 39 and one of the chip bodies 32 to move to the end of the collection frame 37, and the connecting seat 44 realizes linear motion with the help of the hydraulic push rod 43, the chip body 32 will be clamped by the pneumatic clamp 47, and the hydraulic push rod 43 will be used again to drive the connecting seat 44 to reset. Before this, the heat dissipation fin 53 will be moved to the upper end surface of the fixed platform 51 with the help of the second moving platform 52. Then the telescopic end of the third electric push rod 511 drives the side plate 512 and the push plate 513 to move on the upper end surface of the fixed platform 51, and the heat dissipation fin 53 located on the fixed platform 51 is pushed by the push plate 513. When it moves to the end of the stop block 514, the push plate 513 can be reset. At this time, the hydraulic push rod 43 drives the chip body 32 clamped by the pneumatic clamp 47 to reset. Then the transmission motor 441 drives the threaded screw 442 to rotate, and the threaded sleeve 451 cooperates with the threaded screw 442 to realize the second support. The support frame 45 moves downward, and then the chip body 32 is placed in the inner groove of the heat sink 53. The heat sink 53 and the chip body 32 are limitedly connected by the screw locking machine 46 to form a whole. Then the screw locking machine 46 moves upward with the help of the threaded screw 442. At this time, the telescopic end of the fourth electric push rod 561 drives the forward plate 562 to move. The combined heat sink 53 and chip body 32 will be moved by the forward plate 562 and moved to the collection frame below through the slide plate 515.

[0053] Regarding the adjustment of the heat dissipation fins 53: a monitoring platform 54 and a visual sensor 55 are provided on the outer wall of the second movable platform 52. The visual sensor 55 is used to detect the installation position of the heat dissipation fins 53 to ensure the accuracy of the installation position. When the position of the heat dissipation fins 53 is wrong, the visual sensor 55 is used to transmit the data to the controller 2, and the controller 2 controls the two propulsion mechanisms 6 to work, thereby playing the role of pushing the guide frame 71. There are two situations for the position of the heat dissipation fins 53. Only two ideas are provided as a reference. One is that the groove for placing the chip body 32 is correct, but the position of the nut hole is inaccurate. The other is that the groove is downward but the position of the nut hole is correct. In the first case, only After the heat dissipation fins 53 are clamped by the electric clamp 75, the driving rod 741 is driven by the driving motor 74, and the rotation of the fixing plate 733 is realized with the cooperation of the lower toothed disc 874 and the two-way toothed disc 872, the electric clamp 75 can be driven to rotate. At this time, the nut hole position of the heat dissipation fin 53 is rotated 180 degrees, and then the heat dissipation fin 53 can be released. For the second case, the heat dissipation fin 53 is first clamped by the electric clamp 75. Since the clamping plate 861 is provided on the opposite side of the movable clamping claw 751, when the groove position of the heat dissipation fin 53 needs to be adjusted, the telescopic end of the seventh electric push rod 87 needs to be used to drive the sleeve 871 to move up. At this time, the two-way toothed disc 874 is rotated 180 degrees. 872 is separated from the lower toothed disc 874 and is engaged with the upper toothed disc 873. Therefore, when the driving rod 741 rotates, it can drive the upper toothed disc 873 to rotate through the bidirectional toothed disc 872, and drive the second synchronous wheel 813 to rotate through the upper toothed disc 873. Since a synchronous belt 814 is provided on the outer wall of the second synchronous wheel 813 and the first synchronous wheel 812, the first synchronous wheel 812 will drive the coaxial first gear 821 and the second gear 822 to engage and transmit, and drive the spline shaft 86 to rotate through the first sprocket 823, the second sprocket 824 and the chain 825. Since the spline shaft 86 is fixedly connected to one of the splints 861, and the other splint 861 is fixedly connected to the second splint 861, the second splint 861 is fixedly connected to the second splint 861. It is connected to the movable clamp 751 through a bearing, so when the clamp 861 rotates, the restricted heat sink 53 will rotate so that the groove of the mounting chip body 32 is in an upward state, so that it is accurate during the installation process. Since the electric clamp 75 needs to clamp the heat sink 53, the interval between the two movable clamps 751 will be set according to the length of the heat sink 53 to ensure that the moving distance of the two movable clamps 751 will not be too large, thereby affecting the spline shaft 86. In both cases, the clamping of the heat sink 53 will be achieved with the help of the propulsion mechanism 6 to achieve synchronous movement to ensure that there will be no gaps in the process of continuous transportation of the heat sink 53.
