[0005] The solution of the utility model to solve the above technical problems is:

[0006] A continuous processing device for the housing of a cooling fan includes a main frame. A driving mechanism is installed below the top plate of the main frame.

[0023] In an embodiment, as shown in Figures 1 to 5 , a continuous processing device for a heat dissipation fan housing includes a main frame 50. A driving mechanism is installed below the top plate of the main frame 50. The driving mechanism drives a rotating impeller 60 fixed above the top plate of the main frame 50 to rotate. A rotating disk 51 is movably connected to the top surface of the top plate of the main frame 50 through a bearing. The rotating impeller 60 is above the rotating disk 51. The rotating impeller 60 drives the rotating disk 51 to rotate. A plurality of processing limit blocks 52 are fixed on the top surface of the edge of the rotating disk 51. A downwardly extending installation groove 53 is formed in the middle of the top surface of the processing limit block 52. The housing 100 of the heat dissipation fan to be processed is placed in the corresponding installation groove 53;

[0024] A plurality of support seats 70 are fixed on the top surface edge of the top plate of the main frame 50. All the support seats 70 are located outside the rotating disk 51 and are arranged along the rotating disk 51. A plurality of power heads 80 are fixed on the support seats 70. The processing head 81 at the bottom end of the power head 80 faces the corresponding installation groove 53;

[0025] A guide rail fixing plate 10 and a push rod fixing seat 20 are fixed on the top plate of the support seat 70 on one side of the rotating disk 51;

[0026] A push cylinder 21 is fixed on the push rod fixing seat 20. The end of the push rod of the push cylinder 21 is installed with a moving frame 30. A sliding block 31 is fixed on the bottom plate of the moving frame 30. A guide rail 11 is fixed on the guide rail fixing plate 10. The guide rail 11 is inserted into a guide chute formed on the bottom surface of the sliding block 31;

[0027] A grasping mechanism is installed on the moving frame 30. The grasping mechanism faces one of the installation grooves 53.

[0028] The grasping mechanism is as follows: A lifting cylinder 32 is fixed on the moving frame 30. The bottom end of the push rod of the lifting cylinder 32 is fixed with a lifting connecting plate 33. An air cylinder finger 40 is fixed on the bottom surface of the lifting connecting plate 33. The two fingers 41 at the lower part of the air cylinder finger 40 clamp the central shaft 101 formed in the middle of the top surface of the bottom plate of the housing 100.

[0029] Furthermore, end connection plates 12 are fixed to the top surfaces of the left and right ends of the guide rail fixing plate 10. Pressure sensors 13 are fixed to both end connection plates 12. The sensing ends of the pressure sensors 13 extend out of the inner end surfaces of the corresponding end connection plates 12 and correspond to the left or right end of the sliding block 31. The positions of the sliding block 31 can be sensed by the two pressure sensors 13, and the state of the push rod of the push cylinder 21 can be obtained.

[0030] Furthermore, the lifting cylinder 32 is a cylinder with a guide rod, and the bottom end of the guide rod is fixed to the top surface of the lifting connection plate 33.

[0031] Furthermore, arc-shaped grooves are formed on the inner side walls of the lower ends of the two fingers 41 of the pneumatic finger 40.

[0032] Furthermore, an anti-slip elastic layer 1 is fixed to the inner side wall of the arc-shaped groove. This structure can improve the clamping firmness effect.

[0033] Furthermore, the driving mechanism is a driving servo motor, which is fixed to the bottom surface of the middle part of the top plate of the main frame 50. The top end of the output shaft at the top of the driving servo motor 59 extends out of the top surface of the top plate of the main frame 50 and is fixed to the bottom surface of the bottom plate of the hub of the rotating impeller 60. A plurality of blades 61 are fixed to the outer side wall of the hub of the rotating impeller 60. All the blades 61 are evenly distributed on the outer side wall of the hub with the central axis of the rotating impeller 60 as the center. The blades 61 are located between the corresponding two processing limit blocks 52.

[0034] Furthermore, a plurality of vertical sensing columns 511 are fixed to the bottom edge of the bottom surface of the rotating disk 51. The vertical sensing columns 511 are located directly below the middle parts of the corresponding processing limit blocks 52. The bottom end of the vertical sensing column 511 corresponds to the sensing end of the proximity switch 58 fixed to the top surface of the top plate of the main frame 50. When the rotating disk 51 rotates, the sensing end of the proximity switch 58 senses the bottom end of the corresponding vertical sensing column 511, indicating that the rotating disk 51 rotates one station and rotates in place, ensuring the accuracy of subsequent processing.

[0035] Furthermore, a vertical connection plate 34 is fixed to the side wall of the moving frame 30, and the side wall of the lifting cylinder 32 is fixed to the outer side wall of the vertical connection plate 34.

[0036] Furthermore, the end of the push rod of the push cylinder 21 extends out of the outer side wall of the vertical connection part of the push rod fixing seat 20 and is fixed with an elastic connection block 3. The other end of the elastic connection block 3 is fixed with a side connection seat 4, and the side connection seat 4 is fixed to the side wall of the moving frame 30.

[0037] The elastic connection block 3 can have a certain buffering effect when the push rod of the pushing cylinder 21 is pushed. When it pushes the pushing block 22 to move in place, its sliding block 31 will press against the sensing end of the corresponding pressure sensor 13. The elastic connection block 3 can reduce the impact force during collision and improve the service life of related components.

[0038] When this embodiment is in use, the housing 100 to be processed can be first placed in the installation groove 53 of the processing limit block 52 at the first processing position. At the same time, an electromagnet block is fixed at the bottom of the processing limit block 52. By turning on the electromagnet block, the housing 100 can be adsorbed and fixed (the electrical connection wires of all electromagnet blocks can be connected through a rotary electrical connector, which is a conventional structure and will not be elaborated here). The first processing position 9 is located on the left side of the grasping mechanism. Then, by driving the servo motor 59 to operate, the rotating impeller 60 rotates. By the blade 61 leaning against the corresponding processing limit block 52, it is moved. At this time, the rotating disk 51 is driven to rotate (this embodiment rotates counterclockwise). When the sensing end of the proximity switch 58 below senses the bottom end of the corresponding vertical sensing column 511, it means that it rotates one station. At this time, the processing head 81 at the bottom of the corresponding power head 80 descends and rotates to process the housing 100 below it. At this time, the housing 100 to be processed subsequently can be placed in the installation groove 53 at the first station. In this way, connection processing is achieved in sequence until the housing 100 is at the station below the two fingers 41. At this time, the corresponding electromagnet block is turned off. Then, the push rod of the pushing cylinder 21 retracts in place. At this time, the lower parts of the two fingers 41 are on both sides of the central axis 101 of the housing 100. By operating the pneumatic finger 40, the two fingers 41 are brought closer together to clamp the central axis 101. Then, by retracting the push rod of the lifting cylinder 32, the housing 100 is lifted out of the corresponding installation groove 53. Then, by pushing the push rod of the pushing cylinder 21, it is moved to the upper part of the conveyor belt of the corresponding conveying device (which is a conventional structure and will not be elaborated here and is not shown in the drawings) at the outer end. Then, by pushing the push rod of the lifting cylinder 32, the housing 100 is brought closer to the top surface of the upper belt body of the conveyor belt. Then, by operating the pneumatic finger 40, the two fingers 41 are moved away from each other, and the housing 100 is placed on the conveyor belt and conveyed to subsequent equipment. It does not require manual handling, greatly reducing the manual labor intensity.

[0039] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
