Bevel wedge type screw distributing mechanism

Abstract

The invention discloses an automatic distributing mechanism used as the distributing and feeding part of the automatic distributing mechanism of the small screw automatic feeder and the like. The automatic distributing mechanism comprises a power head, a guide block and a material blowing pipe, wherein the guide block is provided with a guide slot, the inner side of the guide block is provided with a material pushing block, the material pushing block is provided with a material holding cavity fitting with screws, the guide slot on the guide block is communicated with the material holding cavity on the material pushing block, a material guiding plate with an inclined plane is arranged above the material pushing block, the inclined plane of the material guiding plate extends to the upward side of the inner side of the guide block, the material blowing pipe is arranged on the guide block, and the power head is an air cylinder. As the material holding cavity which is arranged on the material pushing block and fit with screws is adopted, the action that the barrier plate is inserted in the gap of two screws to distribute material is eliminated, the distributing reliability of small screws is increased, the distributing efficiency can be improved, and the automatic assembly efficiency of the electronic assembly industry can be greatly increased.

Description

technical field [0001] The invention relates to an automatic material distributing mechanism, which is used for the distributing and feeding part of automatic feeding mechanisms such as small screw automatic feeding machines. Background technique [0002] The material distribution of the screw is to take out the first screw from a row of screws arranged side by side to the designated position as required. The current screw distributing mechanism such as figure 1 As shown, the working principle is: the power head 1 drives the sliding block 6 to move to the right along the guide groove of the support 15, and the blocking plate 7 fixed on the sliding block 6 separates the first screw 3 from other screws; The pin 5 on the sliding block 6 drives the supporting plate 4 to move backward through the chute on the stripping plate 4 to break away from the screw 3, and the lower part of the screw 3 falls into the blowing pipe 8 without support. [0003] However, there are problems whe...

Problems solved by technology

[0003] However, there are problems when this distributing mechanism is used for the automatic dispensing and feeding of small screws with a pitch < M1.5, mainly: the distributing mechanism is inserted into the blocking plate from the gap between the two screws for breaking, when the screw is very small Next, the gap between the screws becomes smaller accordingly, plus the possible inclination of the screw during movement, and the blocking plate itself has a certain thickness, making it unreliable to insert the blocking plate, and it is not easy to insert into the gap between the two screws
