Description

Technical Field

[0002] In the semiconductor packaging process, the assembly of heat sink fins and pin chips is a key link to improve the heat dissipation effect. From the perspective of device structure, the semiconductor packaging process can be subdivided into chip level, packaging level and printed circuit level. At the chip level, the outermost layer of the chip is metallized, the electrodes are left empty, and the electrode leads are ready to be drawn out; the packaging 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 the fin heat sink is to transfer the heat of the chip to the fins through heat conduction, and then the fins rely on convection heat transfer to transfer the heat to the surrounding air.

[0003] In the current assembly process of heat sink fins and chip bodies, the precise installation and positioning of heat sink fins has always been a technical challenge. Since the heat sink fins must be tightly combined with the chip body to ensure efficient heat conduction performance, the installation position of the heat sink fins must be accurate. Once the position of the heat sink fins deviates during movement, it will lead to inaccurate installation holes, which usually require manual adjustment or repositioning, which not only increases the operational complexity of the production line, but also reduces production efficiency.

[0020] By adopting the above technical solution, the first moving mechanism 3 and the second moving mechanism 5 cooperate precisely to realize the fast and accurate transportation of the chip body 32 and the heat sink fins 53. Both of these moving mechanisms adopt advanced driving technology and positioning algorithms, which can ensure that they can still maintain a stable motion trajectory and a high degree of positioning accuracy in a complex production environment. The locking mechanism 4 makes the connection between the chip body 32 and the heat sink fins 53 more firm and reliable, ensuring that the two are closely fitted during the assembly process, effectively improving the heat dissipation effect and service life.

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 telescopic end of the hydraulic push rod 43 is fixedly connected to the outer wall of the connecting seat 44. The upper end surface of the connecting seat 44 is fixedly connected with 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 a first bearing frame 443 is fixedly connected to the end of the threaded screw 442 inside the connecting seat 44, and the end of the threaded screw 442 is rotatably sleeved with the threaded screw 442 through a bearing, and a second support frame 45 is slidably connected to the inside of the connecting seat 44, and a threaded sleeve 451 threadedly sleeved with the threaded screw 442 is fixedly connected to the side of the second support frame 45 close to the mounting plate 42, and a thread locking machine 46 is fixedly connected to the inside of the second support frame 45, and a pneumatic clamp 47 for clamping the chip body 32 is fixedly connected to the outer wall of the thread locking end of the thread locking machine 46.

[0024] By adopting the above technical scheme, the auxiliary frame 41 serves as the basic supporting 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 of various components during the locking process, further improving the locking efficiency.

Through the carefully designed third electric push rod 511, the second moving mechanism 5 realizes the precise pushing of the heat dissipation 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 dissipation fins 53 to push 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, and 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.

This arrangement is not only convenient for access and transportation, but also effectively avoids damage and loss of the heat sink fins 53 during storage. At the same time, the second movable platform 52 and the fixed platform 51 are designed to be connected internally, so that the heat sink fins 53 can 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 sink fins 53 in real time, and promptly discover and deal with potential problems. The visual sensor 55 is connected to the controller 2 through an electrical signal, and can collect image information of the heat sink fins 53 in real time, and perform accurate analysis and processing. By comparing the actual hole position of the heat sink fin 53 with the preset standard, the visual sensor 55 can accurately determine whether the heat sink 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 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 by 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.

It is connected to a positioning frame 811, and the other end of the positioning frame 811 is fixedly connected to a gear frame 82. The inner top end of the gear frame 82 is rotatably sleeved with a 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 a limiting plate 84. The side of the limiting plate 84 away from the gear frame 82 is rotatably sleeved with a second gear 822 meshing with the first gear 821 through a bearing. The outer side wall of the limiting plate 84 is fixedly connected to a clamping frame 83 rotatably sleeved with the fixed plate 733.

[0036] By adopting the above technical solution, the positioning plate 81 is used as the basic frame of the transmission mechanism 8. The rotation sleeve of the positioning plate 81 and the driving rod 741 through the bearing ensures that the driving rod 741 can stably drive the positioning plate 81 and its auxiliary components to rotate together when rotating, which not only improves the overall structural strength of the transmission mechanism 8, but also ensures the accuracy and stability of the rotation action. The rotation of the driving rod 741 can drive the second synchronous wheel 813 to rotate together, and then drive the first synchronous wheel 812 to rotate through the transmission effect of the synchronous belt 814, which not only realizes the efficient transmission of power, but also ensures the synchronization and coordination of the rotation action. The first gear 821 is coaxially connected with the first synchronous wheel 812 to ensure that the rotation action between them is consistent. The meshing transmission of the second gear 822 and the first gear 821 realizes the precise control of the rotation speed and direction.

[0037] See also Fig.11 , Fig.12 and Fig.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, 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, 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 toothed disc 873 rotatably sleeved with the driving rod 741, the upper end face of the fixed plate 733 is fixedly connected with a lower toothed disc 874, the outer wall of the driving rod 741 is slidably sleeved with a two-way toothed 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 toothed disc 872, and the two-way toothed disc 872 is meshed with the upper toothed disc 873 or the lower toothed disc 874 for transmission.

[0038] By adopting 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, and 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 with 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 clamping plate 861 and is rotatably sleeved through the inner wall of the second bearing frame 85, ensuring the stability and accuracy of the clamping 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, the position can be adjusted as the spline shaft 86 moves, thereby realizing precise control of the clamping plate 861 and the heat dissipating fins 53.

[0039] Assembling the heat sink 53 and the chip body 32: the chip body 32 and the heat sink 53 are moved by the first moving platform 31 and the second moving 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 overlong pins of the chip body 32. When it moves to the inside of the collection frame 37, it will be located above the push frame 39. At this time, the telescopic end of the second electric push rod 38 drives the push frame 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 push plate 513 is used to push the heat dissipation fin 53 on the fixed platform 51. 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 plate 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 fin 53, and the heat sink fin 53 and the chip body 32 are limitedly connected by the thread locking machine 46 to form a whole. Then the thread 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, and the combined heat sink fin 53 and the chip body 32 will be moved under the push of the forward plate 562, and moved to the collection frame below through the slide plate 515; Regarding the adjustment of the heat dissipation fins 53: a monitoring platform 54 and a visual sensor 55 are arranged on the outer side wall of the second movable platform 52, and 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 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, and only two ideas are provided as references. One is that the groove for placing the chip body 32 is correct, but the position of the nut hole is inaccurate, and 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 fin 53 is clamped by the electric clamp 75, the driving rod 741 is driven by the driving motor 74, and the fixing plate 733 is rotated with the cooperation of the lower toothed disc 874 and the two-way toothed disc 872, and then 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 it is necessary to adjust the groove position of the heat dissipation fin 53, it is necessary to use the telescopic end of the seventh electric push rod 87 to drive the sleeve frame 871 to move up. At this time, the two-way toothed disc 872 is separated from the lower toothed disc 874 and meshed with the upper toothed disc 873. Therefore, when the driving rod 741 rotates, the upper toothed disc 873 can be driven to rotate through the bidirectional toothed disc 872, and the second synchronous wheel 813 can be driven to rotate through the upper toothed disc 873. Since a synchronous belt 814 is provided on the outer walls 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 mesh and transmit after the rotation, 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 clamping plates 861, and the other clamping plate 861 is fixedly connected to the second clamping plate 861, the second clamping plate 861 is fixedly connected to the second clamping plate 861. It is connected to the movable clamp 751 through a bearing, so when the clamp 861 rotates, the limited heat sink 53 will rotate so that the groove of the mounting chip body 32 is in an upward state, thereby making it 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 is not too large, thereby affecting the spline shaft 86. In both cases, the clamping of the heat sink 53 will achieve synchronous movement with the help of the propulsion mechanism 6 to ensure that there will be no gaps in the process of continuous transportation of the heat sink 53.
