[0038] In order to illustrate the technical solution of the present invention, a specific embodiment is provided below, in which only the parts related to the embodiment of the present invention are shown.

[0039] Example:

[0040] like Figure 1-2 As shown, the utility model provides a punching device for a heat sink, comprising: a machine platform 1, and a conveying mechanism 2, a first pushing mechanism 3, a second pushing mechanism 4 and a punching mechanism 5 arranged on the machine platform 1; the first pushing mechanism 3 is vertically arranged at the end of the conveying mechanism 2, the second pushing mechanism 4 is parallelly arranged at one side of the conveying mechanism 2, and the punching mechanism 5 is arranged on the side of the first pushing mechanism 3; the first pushing mechanism 3 is used to receive the heat sink 10 conveyed by the conveying mechanism 2, and combined with the second pushing mechanism 4 to push the heat sink 10 into the punching mechanism 5 for punching.

[0041] Specifically, if Figure 1 As shown, the first push mechanism 3 is arranged at the end of the conveying mechanism 2 and is perpendicular to the conveying mechanism 2. The second push mechanism 4 is arranged in parallel on one side of the conveying mechanism 2 and is arranged vertically on one side of the first push mechanism 3. The punch mechanism 5 is arranged vertically on the other side of the first push mechanism 3 and is located on the same straight line as the second push mechanism 4. The punch mechanism 5 is arranged within the working stroke range of the second push mechanism 4.

[0042] During operation, it is necessary to manually place the heat sink 10 on the conveying mechanism 2 so that the conveying mechanism 2 conveys the heat sink 10. The heat sink 10 conveyed by the conveying mechanism 2 will fall into the first pushing mechanism 3. After the heat sink 10 falls into the first pushing mechanism 3, the first pushing mechanism 3 will operate to move the position of the heat sink 10 to the front side of the second pushing mechanism 4. At this time, the second pushing mechanism 4 will operate to push the heat sink 10 forward and push the heat sink 10 to the punching mechanism 5 for punching. After the punching is completed, the second pushing mechanism 4 will start and continue to push the heat sink 10 that has completed the punching operation forward to complete the unloading of the heat sink 10.

[0043] In the utility model, the heat sink 10 can be automatically transported and punched under the action of the conveying mechanism 2, the first pushing mechanism 3, the second pushing mechanism 4 and the punching mechanism 5, thereby improving the punching efficiency and eliminating the need for manual placement of the heat sink 10 at the punching position, thereby improving safety.

[0044] As an optional implementation, Figure 1-3As shown, the punching device further includes a fixed slot 6, and the first pushing mechanism 3 is arranged in the fixed slot 6; a first through hole 61 is arranged on the side of the fixed slot 6 adjacent to the conveying mechanism 2, and the heat sink conveyed by the conveying mechanism 2 enters the first pushing mechanism 3 through the first through hole 61. A second through hole 62 is arranged on the side of the fixed slot 6 adjacent to the second pushing mechanism 4, and a third through hole 63 is arranged on the side adjacent to the punching mechanism 5, and the second through hole 62 and the third through hole 63 are arranged opposite to each other on the side of the fixed slot 6; after the first pushing mechanism 3 pushes the heat sink 10 to the front end of the second pushing mechanism 4, the second pushing mechanism passes through the second through hole 62 and pushes the heat sink 10 from the third through hole 63 to the punching mechanism 5.

[0045] Specifically, the fixed groove 6 is fixedly arranged on the machine 1, which is convenient for conveying the heat sink 10 on the conveying mechanism 2, the first pushing mechanism 3 and the second pushing mechanism 4, so that the conveying mechanism 2, the first pushing mechanism 3 and the second pushing mechanism 4 can cooperate accurately, and the heat sink 10 can be pushed to the punching mechanism 5 for punching more conveniently and accurately, thereby improving the conveying efficiency of the heat sink 10 and providing the prerequisite for improving the punching efficiency of the heat sink 10.

[0046] As an optional implementation, Figure 2-3 As shown, the first pushing mechanism 3 includes a first cylinder 31 and a first pushing plate 32, and the first pushing plate 32 is fixedly connected to the first cylinder 31; a groove 321 is provided in the first pushing plate 32, and the conveying mechanism 2 can convey the heat sink 10 to the groove 321 through the first through hole 61, and the first pushing plate 32 is driven by the first cylinder 31 to move the position, and the heat sink 10 is driven to the front side of the second pushing mechanism 4. The first pushing mechanism 3 also includes a sensor 324, which is arranged on the first pushing plate and located above the groove 321; after the sensor 324 senses that the heat sink 10 has accurately fallen into the groove 321, the first cylinder 31 is activated to drive the first pushing plate 32 to move the position.

[0047] Specifically, the first push mechanism 3 is arranged at the end of the conveying mechanism 2, and the first cylinder 31 and the first push plate 32 are both arranged in the fixed groove 6. The first through hole 61 is arranged on the fixed groove 6 and the setting position is adjacent to the conveying mechanism 2. The position of the first through hole 61 corresponds to the position of the groove 321 on the first push plate 32. The heat sink conveyed by the conveying mechanism 2 can directly pass through the first through hole 61 on the fixed groove 6 and directly enter the groove 321 of the first push plate 32. It should be noted that the size of the groove 321 matches the size of the heat sink.

[0048] like Figure 2 , Figure 5As shown, the first cylinder 31 includes a cylinder body 311 and a cylinder rod 312, the first push plate 32 includes a push plate 322 and a side plate 323, the push plate 322 is fixedly connected to the side plate 323 and is an integrated structure, the bottom of the push plate 322 is movably connected to the fixed groove 6, one end of the cylinder rod 312 is fixedly connected to the cylinder body 311, and the other end is fixedly connected to the side plate 323, the cylinder body 311 can drive the cylinder rod 312 to move, and at the same time drive the push plate 322 to move, so that the heat sink 10 that falls into the groove 321 moves.

[0049] The first pushing mechanism 3 is also provided with a sensor 324 for sensing whether the heat sink 10 accurately falls into the groove 321. The sensor 324 is provided on the side plate 323 and above the groove 321. After the sensor 324 senses that there is a radiator in the groove 321, it will send a signal to the control system, and the control system will control the first cylinder 31 to move, drive the first pushing plate 32 to move, and move the heat sink 10 to the front of the second pushing mechanism 4. The sensor 324 in this embodiment is preferably an infrared sensor 324.

[0050] It should be noted that the stroke range of the first cylinder 31 in the first pushing mechanism 3 is the distance between the conveying mechanism 2 and the second pushing mechanism 4, that is, the distance between the first through hole 61 and the second through hole 62 on the side of the fixing groove 6. This setting is to avoid errors in the stroke of the first cylinder 31, which may affect the second pushing mechanism 4 in pushing the heat sink 10. The setting of the first pushing mechanism 3 can accurately and stably convey the heat sink 10 to the front of the second pushing mechanism 4, ensuring the pushing efficiency and accuracy.

[0051] As an optional implementation, Figure 2 As shown, the second pushing mechanism 4 includes a second cylinder 41 and a second pushing plate 42, and the second pushing plate 42 is fixedly connected to the second cylinder 41; the second cylinder 41 is used to push the second pushing plate 42, so that the second pushing plate 42 pushes the heat sink in the groove 321 on the first pushing plate 32 into the punching mechanism 5.

[0052] Specifically, the second pushing mechanism 4 is arranged parallel to the conveying mechanism 2 and perpendicular to the first pushing mechanism 3. After the conveying mechanism 2 conveys the heat sink 10 to the first pushing mechanism 3, the first cylinder 31 in the first pushing mechanism 3 drives the first pushing plate 32 to move the position, driving the heat sink 10 to the front of the second pushing mechanism 4, so that the second pushing mechanism 4 pushes the heat sink 10 into the punching mechanism 5 for punching.

[0053] The second pushing mechanism 4 includes a second cylinder 41 and a second pushing plate 42, and the second cylinder 41 is directly connected to the second pushing plate 42. The punching mechanism 5 is arranged on the side of the first pushing mechanism 3 and is arranged on the same line as the second pushing mechanism 4. After the first pushing mechanism 3 pushes the heat sink 10 to the front of the second pushing mechanism 4, the second pushing plate 42 will pass through the second through hole 62 of the fixing groove 6 under the action of the second cylinder 41, and push the heat sink 10 in the groove 321 of the first pushing mechanism 3 from the third through hole 63 of the fixing groove 6 into the punching mechanism 5. After the second pushing mechanism 4 pushes the heat sink 10 to the punching mechanism 5, it will fix the heat sink 10, and the punching mechanism 5 will punch the heat sink 10. After the punching is completed, the second pushing mechanism 4 will further push out the punched heat sink 10 and unload it.

[0054] It should be noted that the second pushing device has two different functions. The first is to push the heat sink 10 in the first push plate 322 mechanism into the punching mechanism 5, limit the heat sink 10 mechanism, and enable the punching mechanism 5 to punch the heat sink 10. The second is to push the heat sink 10 out and unload it after the heat sink 10 is punched. The setting of the second pushing mechanism 4 in this embodiment can push the heat sink 10 into the punching mechanism 5, and cooperate with the punching mechanism 5 to position the heat sink 10, ensure that the punching mechanism 5 punches the heat sink 10, and ensure the punching efficiency while also ensuring the punching quality.

[0055] As an optional implementation, Figure 1 , Figure 4 As shown, the punching device also includes an auxiliary correction mechanism 7, which is arranged between the conveying mechanism 2 and the groove 321 and passes through the first through hole 61. The auxiliary correction mechanism 7 is used to correct the position of the heat sink 10 conveyed by the conveying mechanism 2.

[0056] Specifically, after the heat sink 10 is manually placed on the conveying mechanism 2, due to vibration or other reasons during the conveying process, it is impossible to ensure that the heat sink 10 accurately enters from the first through hole 61 and is conveyed to the specified position in the groove 321. In order to avoid errors, an auxiliary correction mechanism 7 is provided to correct the position of the heat sink 10.

[0057] The auxiliary correction mechanism 7 is arranged through the first through hole 61 and is a groove body that opens upward. The auxiliary correction mechanism 7 has a larger opening on the side adjacent to the conveying mechanism 2, which is convenient for conveying the heat sink 10 from the auxiliary correction mechanism 7 to the groove 321 of the first pushing mechanism 3. The auxiliary correction mechanism 7 has a smaller opening on the side adjacent to the groove 321, which can directly correct the position of the heat sink 10, ensure that the heat sink 10 falls stably into the groove 321, and ensure the accuracy of the loading position. It should be noted that the auxiliary correction mechanism 7 is connected to the fixing groove 6 by screws.

[0058] As an optional implementation, Figure 1 As shown, the punching equipment also includes an anti-fool mechanism 8, which is arranged above the first through hole 61 and is used to block the heat sink 10 with incorrect placement direction. In the process of conveying the heat sink 10 by the conveying mechanism 2, some heat sinks 10 have higher fins on one side and lower fins on the other side. In the process of preventing the heat sink 10 from being placed, the worker may put the heat sink 10 in the opposite direction due to fatigue, resulting in the wrong punching position of the heat sink 10 and the heat sink 10 being scrapped. After the anti-fool mechanism 8 is set, if the heat sink 10 is placed in the wrong direction, the heat sink 10 will be supported by the anti-fool device and cannot pass through the first through hole 61 and the auxiliary correction mechanism 7 to enter the first pushing mechanism 3. After manually discovering that the heat sink 10 is placed in the wrong direction, it can be turned to make it enter the first pushing mechanism 3 correctly, and finally punching is performed at the correct position on the heat sink 10, ensuring the punching quality and reducing the scrap rate, and the structure is simple and easy to operate.

[0059] The foolproof mechanism 8 may be a block fixed by screws, which is not specifically limited in this embodiment.

[0060] As an optional implementation, Figure 3 As shown, the punching mechanism 5 includes a punching part 51, an upper punching die 52 and a lower punching die 53. The punching part 51 is arranged above the upper punching die 52, and the heat sink 10 is punched between the upper punching die 52 and the lower punching die 53 by the punching part 51. A limiting block 54 is arranged on the lower punching die 53, and the limiting block 54 is used to limit the heat sink 10; a blocking block 55 is also arranged on the lower punching die, and the blocking block 55 is arranged on a side away from the first pushing mechanism 3 and can be extended and retracted; when the blocking block 55 is extended, it is used to limit the heat sink 10, and when the blocking block 55 is retracted, the second pushing mechanism 4 can push the heat sink 10 further forward.

[0061] Specifically, the second pusher mechanism 4 can push the heat sink 10 in the groove 321 of the first pusher mechanism 3 to between the upper punching die 52 and the lower punching die 53, and punch holes through the stamping part 51. With the conveying direction of the heat sink 10 as the left side, the front and rear sides of the lower punching die 53 are both provided with limit blocks 54. When punching the heat sink 10, the limit blocks 54 can limit the heat sink 10 in the longitudinal direction. A blocking block 55 is provided on the right side of the lower punching die 53. The blocking block 55 can be extended and retracted. When the blocking block 55 is extended, it can cooperate with the second pusher plate 42 to limit the position of the heat sink 10 that needs to be punched or is being punched in the transverse direction, so as to facilitate the stamping part 51 to punch the heat sink 10. After the punching is completed, the blocking block 55 will retract. After retracting, the second pusher mechanism 4 will act to push out the punched heat sink 10 and discharge it.

[0062] The arrangement of the limiting block 54 and the blocking block 55 in the punching mechanism 5 enables the punching part 51 to punch holes at the correct position on the heat sink 10, thereby ensuring the accuracy of the punching, and further ensuring the quality of the punching while improving the punching efficiency.

[0063] As an optional embodiment, the conveying mechanism 2 includes a motor (not shown in the figure), a roller (not shown in the figure) and a conveyor belt 21, and the motor, the roller and the conveyor belt 21 are connected in sequence so that the heat sink 10 is conveyed on the conveyor belt 21. The heat sink 10 is placed manually, and then can be moved on the conveyor belt 21 under the action of the motor and the roller and conveyed to the first pushing mechanism 3.

[0064] As an optional implementation, Figure 1-3 As shown, the punching device further includes a material unloading mechanism 9, which is arranged at the end of the punching mechanism 5 for unloading materials.

[0065] Specifically, the unloading mechanism 9 is arranged at the end of the punching mechanism 5. After the heat sink 10 is punched, the heat sink 10 is pushed out by the second pushing mechanism 4 and pushed into the unloading mechanism 9 to complete the unloading. It should be noted that the unloading mechanism 9 is an inclined unloading plate. The heat sink 10 after punching can be buffered by the unloading plate and slowly fall into the receiving frame to prevent the heat sink 10 from being damaged.

[0066] As an optional embodiment, the punching equipment also includes a control system, which can control the conveying frequency of the conveying mechanism 2, the action of the first pushing mechanism 3 and the second pushing mechanism 4, and the punching speed of the punching mechanism 5, and adjust its speed or frequency to achieve the purpose of unified control, and can adapt to different types of heat sinks 10 or other workpieces that need to be punched.

[0067] The embodiment is only a special case and does not indicate that the present invention is implemented in such a way.

[0068] The above description is only the preferred embodiment of the present invention. Those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the guidance of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the protection scope of the present invention.
