Technical Field

The utility model relates to the technical field of heat sink processing, in particular to a multi-station processing device for heat sinks.

Background Art

Heat sinks are a commonly used component in the electronics industry. In order to facilitate the connection of heat sinks to components that need heat dissipation, it is usually necessary to perform punching, chamfering and tapping processes on the heat sink to form screw holes that can fit with screws.

In order to effectively improve work efficiency, existing devices concentrate the three processing techniques of punching, chamfering and tapping on the same device to reduce the intermediate transportation process; however, this type of device adopts a linear distribution method, that is, the movement direction of the material is presented in the form of a straight line, and the components of the above three processing techniques are arranged in sequence along the movement direction of the material. This linear distribution method occupies too large an area and is not conducive to the design of the production line.

A further solution is that a limiting block is protruded on the first side wall of the first push block toward the placement position, a limiting step is formed between the limiting block and the first side wall, and an avoidance slope is provided on the second side wall of the limiting block toward the limiting step.

It can be seen that when the first push block moves toward the material on the placement position, the material first passes through the avoidance slope and then enters the limiting step more accurately. The limiting step limits the material on the placement position from two sides of the material, further ensuring the stability of the material on the placement position.

A further solution is that the placement position is formed by providing a positioning strip protruding from the top surface of the placement seat.

It can be seen that the positioning strip protruding from the placement position adapts to the shape of the material, positions the material, and determines the position of the material on the placement seat.

A further solution is that the limiting linear track is formed by a groove arranged on the top surface of the support seat.

It can be seen that the use of grooves to form the limiting linear track allows a concave limiting structure to be naturally formed in the track, allowing the material to move more accurately along the extension direction of the limiting linear track.

A further solution is that the blanking clamp includes a first clamping block and a second clamping block, the first clamping block and the second clamping block are respectively provided with clamping block steps, and the clamping block step of the first clamping block is arranged opposite to the clamping block step of the second clamping block.

A limited linear track 111 is provided on the support seat 11. In the present embodiment, the limited linear track 111 is formed by a groove 112 provided on the top surface of the support seat 11. The groove 112 is used to form the limited linear track 111, so that a concave limiting structure is naturally formed in the track, so that the material can move more accurately and stably along the extension direction of the limited linear track 111. The push block assembly 12 is located at the beginning of the limited linear track 111, and the push block assembly 12 is used to drive the uncut material to move.

The rotating driving device 134 drives one of the gears 133 to rotate, so that when the rotating driving device 134 drives one of the gears 133 to rotate, the two driving wheels are driven to rotate at the same time. The cutting assembly 14 includes a cutting blade 141, a cutting blade rotating assembly 142, and a cutting blade translation assembly 143. The cutting blade translation assembly 143 drives the cutting blade 141 and the cutting blade rotating assembly 142 to move toward or away from the limiting linear track 111. The cutting blade 141 moves between the moving drive assembly 13 and the indexing plate 21. The moving direction of the cutting blade 141 intersects with the extension direction of the limiting linear track 111. The cutting blade rotating assembly 142 drives the cutting blade 141 to rotate. In this embodiment, the moving direction of the cutting blade 141 is perpendicular to the extension direction of the limiting linear track 111, and the cutting blade 141 is circular. When uncut materials are loaded, the mobile drive assembly 13 and the push block assembly 12 simultaneously drive the uncut heat sink to move. When a certain length of the heat sink moves to the placement position 234, the rotating drive device 134 in the mobile drive assembly 13 stops the driving gear 133 from rotating.

The structures of the punching assembly, the upper chamfering assembly and the tapping assembly 4 are similar, and they respectively include a workpiece and a moving drive assembly. The workpiece is a component for achieving the process effect, such as a drill bit specifically used for punching or a drill bit specifically used for tapping. The moving drive assembly uses structural components such as a screw, a motor and a slide rail to drive the workpiece to move in the horizontal and vertical directions, so as to facilitate driving the workpiece to move to the work station for operation. In this embodiment, the punching assembly and the upper chamfering assembly are integrated into one, that is, one workpiece can realize two processes of punching and upper chamfering. The punching upper chamfering assembly 3 includes a punching upper chamfering workpiece 31 and an upper chamfering workpiece moving drive assembly 32.

The lower chamfering assembly 6 includes a lower chamfering workpiece 61 and a fixing seat 62. The lower chamfering workpiece 61 is arranged on the fixing seat 62. The moving direction of the lower chamfering workpiece 61 during operation is vertically upward. In this embodiment, the lower chamfering workpiece 61 is fixed on the fixing seat 62. There is no need to move the driving assembly to drive the lower chamfering workpiece 61 to move. The heat sink is moved between the indexing plate 21 and the lower chamfering assembly 6 by the blanking assembly 5.

When the loading component 1 is loading, the uncut material is manually placed on the limiting linear track 111, and the uncut material is driven to move toward the indexing plate 21 through the push block component 12 and the mobile drive component 13. After a certain length of material has been loaded on the fixed component 23 on the indexing plate 21, the driving of the material movement is stopped, and the rotating cutting blade 141 moves to between the indexing plate 21 and the loading component 1 to cut the material, and resets after completion to realize the automatic loading of the material; the indexing plate component 2 transmits the material to each process component to realize the automation of material transfer, and each process component executes its corresponding process in turn. When the material moves to the unloading component 5, the unloading clamp 51 of the unloading component 5 clamps the material on the fixed component 23, and the unloading clamp 51 drives the material to move to the lower chamfering component 6 for the lower chamfering process. After the lower chamfering process is completed, the unloading clamp 51 moves the material to the unloading collection box 63 to complete automatic unloading. The above-mentioned working process of the device is carried out. The loading component 1 automatically drives the material to move and cut the loading material, the dividing plate component 2 realizes the transfer of the material, and each process component realizes the automation of the process implementation. The unloading component 5 realizes the automatic unloading of the material, so that the device can realize the automation of loading, material transfer and unloading, and effectively improve the work efficiency. In this embodiment, water spraying components can be provided at the punching upper chamfering component 3, the tapping component 4 and the lower chamfering component 6 to cool the heat sink being processed.
