Description

Technical Field

[0001] This utility model relates to the field of power module manufacturing technology, and in particular, to a punching device for a power module housing. Background Technology

[0002] Punching holes in the power module housing is a crucial step in manufacturing heat dissipation vents, typically using metals such as aluminum or copper. The punching equipment includes a stamping mechanism, a loading / unloading mechanism, and a traveling mechanism, enabling automated operation, effectively reducing production risks and improving efficiency. Punching not only facilitates airflow within the power supply and improves heat dissipation, but its automated production also ensures product consistency and reliability.

[0003] For example, Chinese Patent CN218015187U discloses a punching device for a modular power supply housing, including a punching mechanism and a feeding mechanism, a first traveling mechanism, a second traveling mechanism, and an unloading mechanism distributed circumferentially beside the punching mechanism. The first and second traveling mechanisms use multiple cylinders and lead screws to automatically place the housing into and remove it from the punching mechanism. However, the structures of the first and second traveling mechanisms are relatively complex, requiring multiple cylinders and lead screws for transfer mechanisms, which complicates the drive control. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a punching device for the housing of a power module.

[0005] The objective of this utility model is achieved through the following technical solution: A punching device for a power module housing includes a machine base. A feeding mechanism, a punching mechanism, and a discharging mechanism are circumferentially arranged on the machine base. A power ring is rotatably mounted on the machine base, and the power ring has a notch and a toothed structure circumferentially arranged on its upper edge. Two drive wheels are also rotatably mounted on the machine base, spaced apart, with the distance between the two drive wheels greater than the width of the notch, such that at least one drive wheel engages with the toothed structure. Two clamping mechanisms are circumferentially arranged on the power ring, adapted to clamp and release the housing. When the punching mechanism punches, the notch aligns with the punching mechanism.

[0006] Preferably, the two drive wheels are connected to the same drive belt.

[0007] Preferably, the clamping mechanism includes an electric cylinder and a suction nozzle disposed at the end of the ejector shaft of the electric cylinder.

[0008] Preferably, the clamping mechanism includes a clamping rod that is vertically spring-loaded, and a suction nozzle is provided at the end of the clamping rod; a cam groove is provided on the mounting bracket of the power ring, and a cam shaft adapted to the cam groove is provided on the clamping rod; in its natural state, the clamping rod springs to the downward position to drive the suction nozzle to abut against the housing; as the power ring rotates, the cam groove can raise and lower the cam shaft to drive the clamping rod to the upward and downward positions.

[0009] Preferably, the machine base is provided with a mounting platform, the power ring is rotatably mounted on the mounting platform, the mounting platform is constructed with a notch, and the stamping mechanism is located in the notch.

[0010] Preferably, the mounting platform is supported on the machine base by mounting columns.

[0011] Preferably, a drive ring plate is provided on the mounting platform, and the cam groove is constructed on the side wall of the drive ring plate.

[0012] The beneficial effects of this invention are as follows: the rotation of the power ring drives two clamping mechanisms to sequentially face the feeding mechanism, the stamping mechanism, and the unloading mechanism, thereby realizing the automatic loading and unloading of the power module housing. Compared with the prior art, in this invention, the transfer of the clamping mechanism between the feeding mechanism, the stamping mechanism, and the unloading mechanism is achieved solely through the rotation of the power ring, without the need for multiple cylinders and lead screws or other transfer mechanisms, thus reducing the complexity of system control.

[0015] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] like Figures 1 to 3 As shown, a punching device for a power module housing includes a machine base 1. A feeding mechanism 2, a stamping mechanism 3, and a discharging mechanism 4 are arranged circumferentially on the surface of the machine base 1. The specific structures of the feeding mechanism 2, stamping mechanism 3, and discharging mechanism 4 can be found in existing technology and will not be detailed here. The difference lies in that the feeding mechanism 2, stamping mechanism 3, and discharging mechanism 4 are distributed sequentially in the circumferential direction.

[0017] The machine base 1 is also supported by a support column. The mounting platform 16 is spanned between the feeding mechanism 2, the stamping mechanism 3 and the unloading mechanism 4. The mounting platform 16 has a notch 17 at the stamping mechanism 3, so that the stamping mechanism 3 is located in the notch 17, while the feeding mechanism 2 and the unloading mechanism 4 are located below the mounting platform 16.

[0018] A power ring 5 is rotatably disposed on the end face of the mounting platform 16, and a notch 6 is constructed on the power ring 5. For example, by rotating the power ring 5, the power ring 5 can pass through the feeding mechanism 2, the stamping mechanism 3 and the unloading mechanism 4 in sequence; or, the power ring 5 can be rotated so that the notch 6 is opposite to the stamping mechanism 3 so that the stamping mechanism 3, which will be described below, can perform stamping operations.

[0019] For example, the power ring 5 has a toothed structure 7 arranged circumferentially, while the machine base 1 is also rotatably equipped with two spaced-apart drive wheels 8. The two drive wheels 8 are particularly well-suited so that the distance between them is greater than the width of the notch 6, so that no matter what angle the power ring 5 rotates to, there is always a drive wheel 8 that meshes with its toothed structure 7.

[0020] Two clamping mechanisms 9 are arranged circumferentially on the power ring 5, thus the present disclosure can have the following usage process: As the power ring 5 rotates, the first clamping mechanism 9 enters the stamping mechanism 3, where it clamps the outer casing. The second clamping mechanism 9 then faces the feeding mechanism 2 and clamps the corresponding outer casing. With continued rotation of the power ring 5, the first clamping mechanism 9 faces the unloading mechanism 4 and places the clamped outer casing into it. The second clamping mechanism 9 then enters the stamping mechanism 3 and places the clamped outer casing into it. With continued rotation of the power ring 5, the notch 6 faces the stamping mechanism 3, and the stamping mechanism 3 then performs the stamping process.

[0021] In some embodiments, two drive wheels 8 can be adapted to be connected to the same transmission belt 10, which can be rotated by a drive source such as a motor. Therefore, in the above-described use, only the rotation angle and start / stop of a single motor need to be controlled, further reducing the complexity of system control.

[0022] The clamping mechanism 9 may include an electric cylinder 11 and a suction nozzle 12 disposed at the end of the ejector shaft of the electric cylinder 11. For example, when the clamping mechanism 9 is driven to rotate to be opposite to the feeding mechanism 2, the electric cylinder 11 may drive the suction nozzle 12 to descend and achieve the suction of the housing.

[0023] Alternatively, the clamping mechanism 9 may include a clamping rod 13 that is vertically movable via an elastic element such as a spring, and a suction nozzle 12 is provided at the end of the clamping rod 13. Furthermore, a drive ring plate 18 is provided on the mounting platform 16, and a cam groove 14 is provided on the side wall of the drive ring plate 18. A camshaft 15 is provided on the clamping rod 13, extending into and fitting within the cam groove 14. During the rotation of the power ring 5, the camshaft 15 moves along the cam groove 14.

[0024] When the aforementioned elastic element is in its natural state, the clamping rod 13 tends to remain lowered to the downward position. In the downward position, the suction nozzle 12 on the clamping rod 13 will abut against the housing. The cam groove 14 is adapted to raise and lower the camshaft 15 during the rotation of the power ring 5.

[0025] For example, when the clamping mechanism 9 is about to be opposite the loading mechanism 2 and the unloading mechanism 4, the trajectory of the cam groove 14 can drive the clamping rod 13 to remain in the upward position, so that it is not easy to collide with the loading mechanism 2 and the unloading mechanism 4. When the clamping mechanism 9 is opposite the loading mechanism 2 and the unloading mechanism 4, the trajectory of the cam groove 14 can drive the clamping rod 13 to enter the downward position to clamp or release the shell. When the clamping mechanism 9 is opposite the stamping mechanism 3, since the camshaft 15 disengages from the cam groove 14, the clamping rod 13 will enter the downward position under the action of the elastic element, which can also achieve clamping or releasing the shell in the stamping mechanism 3.

[0026] For example, the suction nozzle 12 can utilize an electrically driven miniature air pump to provide negative pressure. Alternatively, other negative pressure devices in the prior art can be used, without limitation in this disclosure.

[0027] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
