Description

Technical Field

[0001] This application relates to the technical field of punching equipment, and in particular to a punching and leveling device for a notebook heat sink. Background Technology

[0002] During the manufacturing process, heat sinks need to be punched using stamping equipment.

[0003] During the stamping process, laptop heat sinks may warp and deform in certain areas. To ensure product quality, the deformed heat sinks need to be transferred to a leveling machine for leveling.

[0004] In order to ensure product uniformity, the workpiece needs to be positioned during the stamping and leveling process. However, adjusting the position of the workpiece to achieve positioning takes a certain amount of time, which increases the processing time of the heat sink and reduces the processing efficiency. Utility Model Content

[0005] To improve processing efficiency, this application provides a punching and leveling device for notebook heat sinks.

[0006] This application provides a punching and leveling device for a notebook heatsink, which adopts the following technical solution:

[0007] A punching and leveling device for a laptop heat sink includes a main body, a transfer mechanism, a positioning mechanism, a punching mechanism, and a leveling mechanism. The positioning mechanism, the punching mechanism, and the leveling mechanism are sequentially arranged on the main body along the heat sink processing direction. The transfer mechanism is arranged on the main body for transferring the heat sink. The transfer mechanism can transfer the heat sink on the positioning mechanism to the punching mechanism, the transfer mechanism can transfer the heat sink on the punching mechanism to the leveling mechanism, and the transfer mechanism can transfer the heat sink on the leveling mechanism out.

[0008] By adopting the above technical solution, the heat sink to be processed is placed on the positioning mechanism, which positions the heat sink. Then, the transfer mechanism transfers the positioned heat sink to the punching mechanism for punching. Next, the transfer mechanism transfers the punched heat sink to the leveling mechanism for leveling. Finally, the transfer mechanism transfers the leveled heat sink out. Therefore, the punching and leveling device provided in this application enables the heat sink to be punched and leveled on the same body, thereby reducing the number of positioning operations and the transfer time, and thus improving processing efficiency.

[0009] Optionally, a support block is provided on one side of the main body, and the transfer mechanism includes a first cylinder, a first lifting block, a moving block, a connecting block, a suction cup, and a drive assembly. The cylinder body of the first cylinder is disposed on the support block, the first lifting block is disposed on the piston rod of the first cylinder, the moving block is slidably disposed on the first lifting block through the drive assembly, the connecting block is disposed on the moving block, and the suction cup is disposed on the connecting block.

[0010] By adopting the above technical solution, the suction cup adsorbs the heat sink, the drive component is activated, the drive component drives the moving block to move the first lifting block, the connecting block on the moving block drives the suction cup to move, and the suction cup drives the heat sink to move; the first cylinder is activated, the piston rod of the first cylinder drives the first lifting block to rise and fall, the moving block on the first lifting block drives the suction cup to rise and fall through the connecting block, and the suction cup drives the heat sink to rise and fall; the set transfer mechanism has a simple structure and is easy to operate.

[0011] Optionally, the positioning mechanism includes a first fixing block, a first positioning block, a second cylinder, and a second positioning block. The first fixing block is disposed on the main body, and there are two first positioning blocks, both of which are disposed on the first fixing block. There are two second cylinders, and the cylinder bodies of both second cylinders are disposed on the first fixing block. A second positioning block is connected to the piston rod of each second cylinder. Both the first positioning blocks and the two second positioning blocks abut against the sidewall of the heat sink.

[0012] By adopting the above technical solution, after the heat sink is located on the first fixed block, the two second cylinders are activated. The piston rods of the second cylinders drive the second positioning blocks to move, and the two second positioning blocks push the heat sink to move. When both the two first positioning blocks and the two second positioning blocks are in contact with the heat sink, it indicates that the position of the heat sink has been adjusted. After the position of the heat sink is adjusted, the second cylinders are activated again so that the second positioning blocks no longer contact the heat sink, which facilitates the transfer of the subsequent transfer mechanism.

[0013] Optionally, the punching mechanism includes a second fixed block, a third cylinder, a second lifting block, an upper die, a third fixed block, and a lower die. The second fixed block is disposed on the main body, the cylinder body of the third cylinder is disposed on the second fixed block, and the second lifting block is disposed on the piston rod of the third cylinder. The upper die is disposed on the second lifting block, the third fixed block is disposed on the main body, and the lower die is disposed on the third fixed block and located below the upper die.

[0014] By adopting the above technical solution, the transfer mechanism transfers the positioned heat sink to the lower mold, and then the third cylinder is activated. The piston rod of the third cylinder drives the second lifting block to move towards the heat sink. The second lifting block drives the upper mold to move, so that the upper mold punches the heat sink located on the lower mold.

[0015] Optionally, the leveling mechanism includes a first leveling block, a second leveling block, and a fourth fixing block. The first leveling block is disposed on the second lifting block. The fourth fixing block is disposed on the main body, and the second leveling block is disposed on the fourth fixing block and located directly below the first leveling block.

[0016] By adopting the above technical solution, the transfer mechanism transfers the punched heat sink to the second leveling block. When the lifting block drives the upper die to move, the lifting block will drive the first leveling block to move. In this way, when the upper die punches the heat sink located on the lower die, the first leveling block will level the heat sink located on the second leveling block. Therefore, while the leveling mechanism is performing a leveling operation on one heat sink, another heat sink is being punched. This can shorten the processing time of the same batch of heat sinks and improve the overall efficiency.

[0017] Optionally, the main body is provided with two cleaning mechanisms. Each cleaning mechanism includes a fifth fixing block, a fourth cylinder, an adjusting block, and a cleaning block. The fifth fixing block is disposed on the main body, the cylinder body of the fourth cylinder is disposed on the fifth fixing block, and the adjusting block is disposed on the piston rod of the fourth cylinder. The cleaning blocks are disposed on both sides of the adjusting block. Two cleaning blocks in one of the cleaning mechanisms clean the upper mold and the lower mold, while two cleaning blocks in the other cleaning mechanism clean the first leveling block and the second leveling block.

[0018] By adopting the above technical solution, when no heat sink is located on the lower mold and the second leveling block, there is a certain distance between the upper mold and the lower mold, and a certain distance between the first leveling block and the second leveling block. The fourth cylinder is activated, and its piston rod drives the adjusting block to move. The adjusting block drives the cleaning block to move, causing one cleaning block in one cleaning mechanism to contact the upper mold and the other cleaning block to contact the lower mold, thus cleaning the upper and lower molds. Similarly, one cleaning block in another cleaning mechanism contacts the first leveling block and the other cleaning block to contact the second leveling block, thus cleaning the first and second leveling blocks. The cleaning mechanisms can clean the upper mold, lower mold, first leveling block, and second leveling block, reducing the phenomenon of poor heat sink processing quality due to the presence of foreign objects.

[0019] Optionally, the cleaning block is provided with an installation mechanism, which includes an installation block and an installation component. The cleaning block is disposed on the installation block, and the installation component is disposed on the adjustment block and connected to the installation block.

[0020] By adopting the above technical solution, the mounting block with the cleaning block is installed on the cleaning block through the mounting component. After the cleaning block has been used for a certain period of time, it is easy to replace the cleaning block, thereby ensuring the cleaning effect of the cleaning mechanism.

[0021] Optionally, the mounting assembly includes a locking block and a mounting bolt. The locking block is disposed on the mounting block, and the adjusting block has a locking groove for engaging with the locking block. The mounting bolt passes through the mounting block and is threadedly connected to the adjusting block.

[0022] By adopting the above technical solution, the card block is engaged with the card slot, and the mounting block abuts against the adjusting block; then the mounting bolt passes through the mounting block and is threadedly connected to the adjusting block, thereby fixing the mounting block on the adjusting block; the set mounting component has a simple structure and is easy to operate.

[0023] Optionally, the adjusting block is provided with a reinforcing mechanism, the reinforcing mechanism including a reinforcing block and an adjusting component, the reinforcing block is slidably disposed on the adjusting block, and the locking block is provided with a reinforcing groove for engaging with the reinforcing block; the adjusting component is disposed on the adjusting block and connected to the reinforcing block.

[0024] By adopting the above technical solution, when the mounting block abuts against the adjusting block, the adjusting component drives the reinforcing block to move towards the locking block and engage with the reinforcing groove on the locking block; the set reinforcing mechanism can improve the stability of the mounting block on the adjusting block.

[0025] Optionally, the adjustment assembly includes an adjustment shaft, an adjustment gear, and an adjustment rack. The adjustment shaft is rotatably mounted on the adjustment block, the adjustment gear is keyed to the adjustment shaft, and the adjustment rack is mounted on the reinforcing block and meshes with the adjustment gear.

[0026] By adopting the above technical solution, the adjusting shaft drives the adjusting gear to rotate, and the adjusting rack meshing with the adjusting gear will drive the reinforcing block to move. The set adjusting component has a simple structure and is easy to operate.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The punching and leveling device provided in this application enables the heat sink to be punched and leveled on the same body, thereby reducing the number of positioning operations and transfer time, and thus improving processing efficiency;

The punched heat sink is then transferred to the leveling mechanism 5 for leveling through the transfer mechanism 2.

Then, the second cylinder 33 is activated again, causing the second positioning blocks 34 to move away from the heat sink, so that the suction cup 25 on the connecting block 24 can transfer the heat sink.

In the second cleaning mechanism 6, one cleaning block 64 abuts against the first leveling block 51 and the other cleaning block 64 abuts against the second leveling block 52, thus cleaning the first leveling block 51 and the second leveling block 52.

[0051] refer to Figure 5 and Figure 6The adjusting block 63 has slots 631 on both sides. The cleaning block 64 is provided with an installation mechanism 7, which includes an installation block 71 fixedly connected to the cleaning block 64.

The installation block 71 is provided with an installation bolt 722, which passes through the installation block 71 and is threadedly connected to the adjusting block 63.

[0052] First, engage the locking block 721 with the locking slot 631 on the adjusting block 63, and make the mounting block 71 abut against the adjusting block 63. Then, make the mounting bolt 722 pass through the mounting block 71 and thread it onto the adjusting block 63 to fix the mounting block 71 onto the adjusting block 63.

An adjusting rack 823, meshing with the adjusting gear 822, is integrally provided on the reinforcing block 81.

[0054] When the mounting block 71 abuts against the adjusting block 63, the adjusting shaft 821 is rotated. The adjusting shaft 821 drives the adjusting gear 822 to rotate, the adjusting gear 822 drives the adjusting rack 823 to move, and the adjusting rack 823 drives the reinforcing block 81 to move, so that the reinforcing block 81 engages with the reinforcing groove on the locking block 721.

[0055] The implementation principle of the punching and leveling device for a notebook heat sink according to an embodiment of this application is as follows: the heat sink to be processed is placed on the conveyor belt of the loading rack 13, and then the heat sink is conveyed to the side near the transfer rack 14. The robot arm 15 transfers the heat sink to the positioning space formed by two first positioning blocks 32 and two second positioning blocks 34; then the second cylinder 33 is activated so that the two first positioning blocks 32 and the two second positioning blocks 34 all abut against the heat sink; after the two first positioning blocks 32 abut against the heat sink, the second cylinder 33 is activated so that the second positioning blocks 34 move away from the heat sink.

[0056] The first cylinder 21 and drive assembly 26 are activated, causing the suction cup 25 on one of the connecting blocks 24 of the moving block 23 to transfer the positioned heat sink to the lower mold 46. Then, the third cylinder 42 is activated, causing the upper mold 44 to punch the heat sink located on the lower mold 46. Next, the first cylinder 21 and drive assembly 26 are activated again, causing the suction cup 25 on another connecting block 24 of the moving block 23 to transfer the punched heat sink located on the lower mold 46 to the second leveling block 52. As each suction cup 25 transfers the heat sink to the second leveling block 52, another suction cup 25 will transfer the heat sink to the lower mold 46. Thus, when the lifting block drives the upper mold 44 to move, causing the upper mold 44 to punch the heat sink, the lifting block will drive the first leveling block 51 to move, causing the first leveling block 51 and the second leveling block 52 to perform a leveling operation on the heat sink. Then, the first cylinder 21 and the drive assembly 26 are started, so that the suction cups 25 on the other connecting blocks 24 on the moving block 23 transfer the heat sink that is located on the second leveling block 52 and leveled to the conveyor belt of the unloading rack 16; when one suction cup 25 transfers the heat sink to the conveyor belt of the unloading rack 16, another suction cup 25 will transfer the heat sink to the second leveling block 52.

[0057] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
