Description

Technical Field

[0001] The present invention relates to the technical field of tablet computer production, and particularly to a rapid welding and assembling machine for tablet computer heat sinks. Background Art

[0002] A tablet computer, a small and portable personal computer, is mainly operated through a touch screen. It supports various input methods such as a stylus, a soft keyboard, and voice recognition, and provides excellent mobile audio-visual, gaming, and network application experiences. Its thin and light design and handwriting and voice input functions make it superior to laptop computers in terms of mobility and portability.

[0003] Among them, a heat sink is an essential heat dissipation component for tablet computers and laptop computers. Existing heat dissipation components need to weld the heat sink and the solder pad and then assemble them onto the machine for heat dissipation. Existing heat dissipation components are all formed by manual welding or riveting, and the production efficiency is too low. Especially on an automated production line, an automated welding and assembling structure needs to be designed to cooperate. In order to achieve the full-automatic welding of the heat sink, the existing Chinese patent document CN202122301735.6 discloses a rapid welding and assembling mechanism for tablet computer heat sinks, which includes a workbench, a solder pad feeding device installed on one side of the workbench, a solder pad pushing device connected to the solder pad feeding device, a solder pad picking device for picking up materials on the solder pad pushing device, a welding table located below the solder pad picking device, a heat sink feeding device located on one side of the welding table, and a heat sink picking device for grabbing and placing the heat sink feeding device onto the welding table; the welding table includes a welding fixture for placing the heat sink and a first welding component and a second welding component respectively located on both sides of the welding fixture; this utility model uses automatic feeding of the heat sink and automatic feeding of the solder pad to automatically transport the two to the welding table, welds the solder pad and the heat sink through the welding table, and then grabs and unloads the materials. The overall automation degree is high, so as to realize the automated production of tablet computers, with a high automation degree and a high heat sink welding efficiency; Although the equipment in the above solution can automatically weld the heat sink and the welding, the equipment can only process the automatic welding work of a group of heat sinks and solder pads at a time. Because the entire welding process is that the heat sink is automatically fed and the solder pad is automatically fed to automatically transport the two to the welding table, the solder pad and the heat sink are welded through the welding table, and then grabbed and unloaded. After completing this series of operations, the entire process needs to start over to process the next group of solder pads and heat sinks. Therefore, the welding speed of this equipment is relatively slow, especially when mass-producing heat sinks, its efficiency cannot meet the production requirements. Summary of the Invention

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0018] Embodiment 1: Please refer to Figure 1 and Figure 2, A quick welding and assembling machine for a tablet computer heat sink in the figure, including a workbench 1, and a mounting plate 11 is fixedly connected to the top of the workbench 1 through a bracket; It further includes: a solder chip picking component 2 and a welding component 3 respectively installed on the left and right sides of the mounting plate 11, a heat sink picking component 4 and a blanking component 5 are respectively installed on the front and back sides of the mounting plate 11, and a linkage component 6 is also installed on the top of the mounting plate 11. Through the linkage of the linkage component 6, the solder chip picking component 2, the welding component 3, the heat sink picking component 4 and the blanking component 5 can move simultaneously, which can not only make the actions of picking and placing the solder chip and the heat sink consistent and synchronous, but also make the welding action and the blanking action consistent and synchronous, that is, the entire process has operations of picking, welding and blanking, thereby improving the welding efficiency of the heat sink; A solder chip conveyor belt 14 arranged below the solder chip picking component 2 and a heat sink conveyor belt 15 arranged below the heat sink picking component 4. A round table 12 is installed on the top of the workbench 1 directly below the mounting plate 11. A driving mechanism 7 is connected to the bottom of the round table 12. Four groups of welding jigs 13 are arranged in an annular array on the top of the round table 12. A transmission mechanism 8 is arranged on one side of the bottom of the round table 12. By driving the round table 12 by the driving mechanism 7, it can intermittently rotate 90 degrees, so that the four groups of welding jigs 13 can intermittently move to the specified working positions, and then drive the transmission mechanism 8 to drive, and can also drive the solder chip conveyor belt 14 and the heat sink conveyor belt 15 to work synchronously, that is, the feeding actions of the solder chip and the heat sink are synchronized with the rotation action of the round table 12, further improving the positioning efficiency of the solder chip and the heat sink.

[0019] Further, referring to Figure 3 , the solder chip picking component 2 includes a first connecting plate 21, a first ball nut 22, a first ball screw 23, a first lifting plate 24 and a first pneumatic gripper 25. Two groups of the first ball nuts 22 are symmetrically arranged at both ends of the first connecting plate 21, and the first ball nut 22 is rotatably connected to the first connecting plate 21. The first ball screw 23 is threadedly connected to the first ball nut 22. The first lifting plate 24 is fixed to the bottom of the first ball screw 23.

A first gear 26 is fixedly sleeved on the outside of the first ball nut 22, and a first transmission rack 27 meshing with the first gear 26 is fixed to the bottom of the mounting plate 11.

[0020] Specifically, the linkage component 6 drives the first connecting plate 21 to move linearly, thereby driving the first pneumatic gripper 25 to move to directly above the solder tab conveyor belt 14 first. At this time, due to the driving effect of the first gear 26 and the first transmission rack 27, the first ball nut 22 will also be driven to rotate, causing the first ball screw 23 to drive the first lifting plate 24 to descend. Thus, while moving the first connecting plate 21, its vertical movement can also be driven, enabling the first pneumatic gripper 25 to accurately move to the position of the solder tab to be clamped. Then, the first pneumatic gripper 25 can automatically identify the solder tab for clamping. Finally, the first connecting plate 21 will move towards the top of the welding jig 13 under the control of the linkage component 6, and accurately place the clamped solder tab on the welding jig 13.

[0021] Further, referring to Figure 3 , the welding component 3 includes a second connecting plate 31, a second ball nut 32, a second ball screw 33, a second lifting plate 34, and a welding needle module 35. Two groups of the second ball nuts 32 are symmetrically arranged at both ends of the second connecting plate 31, and the second ball nut 32 is rotatably connected to the second connecting plate 31.

A second gear 36 is fixedly sleeved on the outer side of the second ball nut 32, and a second transmission rack 37 meshing with the second gear 36 is fixed to the bottom of the mounting plate 11.

[0022] Specifically, the linkage component 6 drives the second connecting plate 31 to move linearly, thereby driving the welding needle module 35 to move. At this time, due to the driving effect of the second gear 36 and the second transmission rack 37, the second ball nut 32 will also be driven to rotate, causing the second ball screw 33 to drive the second lifting plate 34 to descend. Thus, while moving the second connecting plate 31, its vertical movement can also be driven, enabling the welding needle module 35 to accurately move to the position above the welding jig 13. The welding needle module 35 can automatically identify the solder tab and the heat sink for welding.

[0023] Further, please refer to Figure 4, the heat sheet picking component 4 includes a third connecting plate 41, a third ball nut 42, a third ball screw 43, a third lifting plate 44 and a second pneumatic gripper 45. Two groups of the third ball nuts 42 are symmetrically arranged at both ends of the third connecting plate 41, and the third ball nut 42 is rotatably connected to the third connecting plate 41. The third ball screw 43 is threadedly connected to the third ball nut 42. The third lifting plate 44 is fixed to the bottom of the third ball screw 43. The second pneumatic gripper 45 is installed at the bottom of the third lifting plate 44 and is used to automatically pick up and release the heat sheet. A third gear 46 is fixedly sleeved on the outside of the third ball nut 42, and a third driving rack 47 meshing with the third gear 46 is fixed to the bottom of the mounting plate 11.

[0024] Specifically, the linkage component 6 drives the third connecting plate 41 to move linearly, thereby driving the second pneumatic gripper 45 to first move directly above the heat sheet conveyor belt 15. At this time, due to the transmission effect of the third gear 46 and the third driving rack 47, the third ball nut 42 will also be driven to rotate, causing the third ball screw 43 to drive the third lifting plate 44 to descend. Thus, while moving the third connecting plate 41, it can also drive its vertical movement, enabling the second pneumatic gripper 45 to accurately move to the position of the heat sheet to be clamped. Then, the second pneumatic gripper 45 can automatically identify the heat sheet and clamp it. Finally, the third connecting plate 41 will move towards the top of the welding jig 13 under the control of the linkage component 6 and accurately place the clamped heat sheet on the welding jig 13.

[0025] Further, referring to Figure 2 and Figure 4 , the blanking component 5 includes a fourth connecting plate 51, a fourth ball nut 52, a fourth ball screw 53, a fourth lifting plate 54 and a third pneumatic gripper 55. Two groups of the fourth ball nuts 52 are symmetrically arranged at both ends of the fourth connecting plate 51, and the fourth ball nut 52 is rotatably connected to the fourth connecting plate 51. The fourth ball screw 53 is threadedly connected to the fourth ball nut 52. The fourth lifting plate 54 is fixed to the bottom of the fourth ball screw 53. The third pneumatic gripper 55 is installed at the bottom of the fourth lifting plate 54 and is used to automatically pick up and release the heat sheet. A fourth gear 56 is fixedly sleeved on the outside of the fourth ball nut 52, and a fourth driving rack 57 meshing with the fourth gear 56 is fixed to the bottom of the mounting plate 11. A storage box 58 is provided at the top of the workbench 1 and at the position directly below the third pneumatic gripper 55.

[0026] Specifically, the linkage component 6 drives the fourth connecting plate 51 to move linearly, thereby driving the third pneumatic gripper 55 to move to directly above the heat sink conveyor belt 15 first. At this time, due to the transmission effect of the fourth gear 56 and the fourth transmission rack 57, the fourth ball nut 52 will also be driven to rotate, causing the fourth ball screw 53 to drive the fourth lifting plate 54 to descend. Thus, while moving the fourth connecting plate 51, it can also drive its vertical movement, enabling the third pneumatic gripper 55 to accurately move to the position of the already welded heat sink. Then, the third pneumatic gripper 55 can automatically identify the heat sink for clamping. Finally, the fourth connecting plate 51 will move towards the top of the storage bin 58 under the control of the linkage component 6, and accurately place the clamped heat sink into the storage bin 58.

[0027] Further, please refer to Figure 5 and Figure 6 As shown in the figure, the linkage component 6 includes a rotary cylinder 61, a rotary disk 62, a connecting rod 63, a slider 64, and a guide rail 65.

The solder paste picking component 2, the welding component 3, the heat sink picking component 4, and the blanking component 5 are respectively fixedly connected to the four groups of the sliders 64.

[0028] Specifically, the rotary cylinder 61 drives the rotary disk 62 to rotate, and the rotary disk 62 drives the four connecting rods 63 to rotate, causing the four sliders 64 to move linearly together on the corresponding guide rails 65. Furthermore, it realizes the synchronous movement of the solder paste picking component 2, the welding component 3, the heat sink picking component 4, and the blanking component 5, ensuring the simultaneous control and movement of the solder paste picking component 2, the welding component 3, the heat sink picking component 4, and the blanking component 5. It can not only make the solder paste picking and placing actions and the heat sink picking and placing actions consistent and synchronous, but also make the welding action and the blanking action consistent and synchronous.

The driving shaft 71 drives the frustum 12 to rotate. The stepping motor 75 can rotate a specified number of turns through the controller, and then through the transmission effect of the gears, so that the driving shaft 71 can intermittently rotate 90 degrees each time. Every time it rotates 90 degrees, the relative positions of the four welding jigs 13 will be automatically exchanged, so that the welding chips and the heat dissipation chips can be continuously supplied synchronously.

[0031] Meanwhile, the transmission mechanism 8 includes a support platform 81, a seventh gear 82, an eighth gear 83, a linkage gear ring 84, a first bevel gear 85, a second bevel gear 86, and a synchronizing member 87.

The first synchronous pulley 875 and the second synchronous pulley 876 are drivingly connected by a toothed synchronous belt.

[0033] Specifically, during the process of the frustum 12 rotating by an angle of ninety degrees, it will drive the linkage gear ring 84 to rotate. The linkage gear ring 84 drives the seventh gear 82 to rotate. The seventh gear 82 drives the eighth gear 83 to rotate. The eighth gear 83 drives the first bevel gear 85 to rotate. The first bevel gear 85 drives the second bevel gear 86 to rotate. The second bevel gear 86 drives the second synchronous pulley 876 to rotate.

The first synchronous pulley 875 drives the first transmission rod 871 to rotate, thereby driving a transmission roller of the solder tab conveyor belt 14 to rotate forward, enabling the solder tab conveyor belt 14 to automatically convey solder tabs one by one at equal intervals. Moreover, the first transmission rod 871 also drives the third bevel gear 873 to rotate. The third bevel gear 873 drives the fourth bevel gear 874 to rotate, causing the second transmission rod 872 to rotate together, and then driving a transmission roller of the heat sink tab conveyor belt 15 to rotate forward, enabling the heat sink tab conveyor belt 15 to drive heat sink tabs to be automatically conveyed one by one at equal intervals. In this way, while ensuring the intermittent rotation of the frustum 12, it can also control the synchronous conveyance of heat sink tabs and solder tabs, eliminating the need for separate power addition for the conveyance of heat sink tabs and solder tabs, saving electrical energy and the intervention of other control systems.
