Description

Technical field:

[0001] The utility model relates to the technical field of heat dissipation fan manufacturing equipment, and more specifically to a shell blanking and grabbing mechanism for a heat dissipation fan. Background technology:

[0002] The existing cooling fan generally includes an upper and lower shell. The lower shell is subjected to a series of processing as required, such as punching. At the same time, a connecting shaft is installed on the top surface of the bottom plate. The existing processing process generally involves manually placing it at the corresponding processing position for processing until all processing is completed, and then placing it on a subsequent conveyor belt and conveying it to subsequent equipment for subsequent processing, which is inefficient.

[0003] Therefore, some now use automatic processing to fix it to facilitate continuous processing. However, in this processing process, when the shell is processed, it needs to be placed in the subsequent equipment. The existing method is to manually place the assembled parts on the conveyor belt of the input conveying device of the subsequent equipment, which increases the amount of manual labor. Utility model content:

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a shell material unloading and grabbing mechanism for a cooling fan, which can be installed in a processing device and is located on one side of a conveyor belt of the conveying device. It can grab the processed shell parts and place them on a subsequent conveyor belt, which is convenient for continuous processing and does not require manual handling and placement in the middle, greatly reducing the amount of manual labor.

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

[0006] A shell material unloading and grabbing mechanism for a heat dissipation fan comprises a guide rail fixing plate and a push rod fixing seat, a push cylinder is fixed on the push rod fixing seat, a moving frame is installed on the end of the push rod of the pushing cylinder, a sliding block is fixed on the bottom plate of the moving frame, a guide rail is fixed on the guide rail fixing plate, and the guide rail is inserted into a guide slide groove formed on the bottom surface of the sliding block;

[0007] A lifting cylinder is fixed on the movable frame, a lifting connecting plate is fixed to the bottom end of the push rod of the lifting cylinder, a pneumatic finger is fixed to the bottom surface of the lifting connecting plate, and two lower fingers of the pneumatic finger clamp the central axis formed in the middle of the top surface of the bottom plate of the shell.

[0008] The left and right top surfaces of the guide rail fixing plate are fixed with end connecting plates, and pressure sensors are fixed on the two end connecting plates. The sensing ends of the pressure sensors extend out of the inner end surfaces of the corresponding end connecting plates and correspond to the left or right end of the sliding block.

[0009] The lifting cylinder is a cylinder with a guide rod, and the bottom end of the guide rod is fixed on the top surface of the lifting connecting plate.

[0010] The inner side walls of the lower ends of the two fingers at the lower part of the pneumatic finger are both formed with arc grooves.

[0011] The outstanding effects of the utility model are:

[0012] It can be installed in the processing equipment and located on one side of the conveyor belt of the conveying equipment. It can grab the processed shell parts and place them on the subsequent conveyor belt, which is convenient for continuous processing and does not require manual handling and placement in the middle, greatly reducing the amount of manual labor. Description of the drawings:

[0013] Figure 1 It is a partial structural schematic diagram of the utility model;

[0014] Figure 2 yes Figure 1 Schematic diagram of the angle-changing structure. Specific implementation method:

[0015] For example, see Figure 1 to Figure 2 As shown, a housing blanking and grabbing mechanism for a heat dissipation fan comprises a guide rail fixing plate 10 and a push rod fixing seat 20, the guide rail fixing plate 10 and the push rod fixing seat 20 are fixed on a rack of an assembly device, the rack can be a conventional rack, which will not be described in detail here; a push cylinder 21 is fixed on the push rod fixing seat 20, a push rod of the push cylinder 21 is installed with a moving rack 30, a sliding block 31 is fixed on the bottom plate of the moving rack 30, a guide rail 11 is fixed on the guide rail fixing plate 10, and the guide rail 11 is inserted into a guide groove formed on the bottom surface of the sliding block 31;

[0016] A lifting cylinder 32 is fixed on the movable frame 30, a lifting connecting plate 33 is fixed to the bottom end of the push rod of the lifting cylinder 32, a pneumatic finger 40 is fixed to the bottom surface of the lifting connecting plate 33, and the two lower fingers 41 of the pneumatic finger 40 clamp the central axis 101 formed in the middle of the top surface of the bottom plate of the shell 100.

[0017] Furthermore, end connecting plates 12 are fixed to the top surfaces of both left and right ends of the guide rail fixing plate 10, and pressure sensors 13 are fixed to both end connecting plates 12. The sensing ends of the pressure sensors 13 extend out of the inner end surfaces of the corresponding end connecting plates 12 and correspond to the left or right end of the sliding block 31. The position 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.

[0018] Furthermore, the lifting cylinder 32 is a cylinder with a guide rod, and the bottom end of the guide rod is fixed on the top surface of the lifting connecting plate 33. This structure can ensure the normal lifting and lowering of the lifting connecting plate 33 without basically deflecting.

[0019] The inner side walls of the lower ends of the two fingers 41 at the lower part of the pneumatic finger 40 are both formed with arc-shaped grooves.

[0020] The inner side wall of the arc-shaped groove is fixed with an anti-skid elastic layer 1, which can improve the clamping firmness without affecting the clamping firmness.

[0021] A first connecting member 2 is fixed to the top surface of one end connecting plate 12 .

[0022] A vertical connecting plate 34 is fixed to the side wall of the moving frame 30 , and a side wall of the lifting cylinder 32 is fixed to the outer side wall of the vertical connecting plate 34 .

[0023] The end of the push rod of the pushing 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 connecting block 3. The other end of the elastic connecting block 3 is fixed with a side connecting seat 4, which is fixed on the side wall of the moving frame 30.

[0024] The elastic connecting block 3 can have a certain buffering effect when pushing the push rod of the push cylinder 21. For example, when it pushes the push block 22 to move into place, the sliding block 31 will press against the sensing end of the corresponding pressure sensor 13. The elastic connecting block 3 can reduce the impact force during collision and increase the service life of related components.

[0025] When this embodiment is in use, it retracts the push rod of the pushing cylinder 21 into place. At this time, the lower parts of the two fingers 41 are on both sides of the central axis 101 of the shell 100. The pneumatic finger 40 is operated to make the two fingers 41 close to each other, thereby clamping the central axis 101. Then, the push rod of the lifting cylinder 32 is retracted to lift the shell 100, and then it is pushed by the push rod of the pushing cylinder 21 to move it to the top of the conveyor belt of the corresponding conveying equipment at the outer end (which is a conventional structure, which is not described in detail here and is not shown in the accompanying drawings). Then, the push rod of the lifting cylinder 32 pushes the shell 100 to approach the top surface of the upper belt body of the conveyor belt. Then, the pneumatic finger 40 is operated to make the two fingers 41 move away from each other, and the shell 100 is on the conveyor belt and is transported to the subsequent equipment through the conveyor belt. It does not require manual handling, which greatly reduces the amount of labor.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
