Abstract

The utility model discloses an automatic distributing mechanism which is used for the distributing part of an automatic feeding mechanism such as the small automatic screw feeder. The screw distributing mechanism comprises a power head, a guide block and a blowing pipe; a guide way is arranged on the guide block, a push block is arranged on the internal side of the guide block, a containing cavity matched with the screws is arranged on the push block, the guide way on the guide block is communicated with the containing cavity on the push block, a guide plate with a bevel is arranged above the push block, the bevel of the guide block is cut off above the internal side of the guide block, the blowing pipe is arranged on the guide block, and the power head is a cylinder. Because the containing cavity matched with the screws is arranged on the push block, the procedure that a retaining plate is inserted in the clearance between two screws for separating the screws is removed, the separation reliability of small screws is improved, the separation efficiency is improved and the automatic assembly efficiency of the electronic automatic assembly industry is improved greatly.

Description

Bevel wedge type screw distributing mechanism

Technical field

The utility model relates to a kind of automatic distributing material mechanism, is used for the branch feeding part of automatic feed mechanisms such as small-sized screw self-propelled material transporter.

Background technology

The sub-material of screw be exactly from front and back mutually by the row screw of arranging, first screw therefrom is fetched into assigned address on request.Present screw distributing mechanism as shown in Figure 1, principle of work is: unit head 1 drive sliding shoe 6 along the guide groove of bearing 15 toward right motion, the barrier plate 7 that is fixed on the sliding shoe 6 separates first screw 3 and other screws; Be fixed in pin 5 on the sliding shoe 6 simultaneously and drive supporting board 4 by the chute on the stripper plate 4 and move backward and break away from screw 3, screw 3 bottoms are not supported to fall into and are blown material and manage in 8.

But, this feeding distribution mechanism has problems when being used for the feeding in automatic minute of small-sized screw of pitch＜M1.5, mainly be: feeding distribution mechanism is to insert barrier plate from the slit of two screws to carry out disjunction, under the very little situation of screw, the slit is corresponding between the screw diminishes, and add inclination possible in the motion process of tightening up a screw, and barrier plate itself has certain thickness, make that inserting barrier plate becomes unreliable, is not easy to insert two slits between screw.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of simple in structure, the small-sized screw distributing mechanism of sub-material failure-free.

The technical solution of the utility model is:

A kind of bevel wedge type screw distributing mechanism, comprise unit head, orienting lug, blow the material pipe, orienting lug is provided with guide groove, the medial surface of orienting lug is provided with expeller, expeller is provided with the material-holding chamber suitable with screw, guide groove on the orienting lug and the material-holding chamber on the expeller connect, and the top of expeller is provided with the stock guide on inclined-plane, and the inclined-plane of stock guide terminates in the medial surface top of orienting lug.

The described material pipe that blows is arranged on the orienting lug.Unit head is a cylinder.

Beneficial effect: the utility model provides the failure-free automatic distributing material mechanism, since adopted be provided with on the expeller with the suitable material-holding chamber of screw, save the slit of two screws of barrier plate insertion and carried out the action of sub-material, the sub-material reliability of small-sized screw is improved, can improve sub-material efficient, can make electronics assemble the automatic assembling efficiency of industry automatically and improve greatly.

Description of drawings

Fig. 1 is a screw distributing mechanism scheme drawing of the prior art;

Fig. 2 is a screw distributing mechanism scheme drawing of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

A kind of bevel wedge type screw distributing mechanism, comprise unit head 1, orienting lug 2, blow material pipe 8, orienting lug 2 is provided with guide groove 13, the medial surface 12 of orienting lug 2 is provided with expeller 9, expeller 9 is provided with the material-holding chamber 14 suitable with screw, guide groove 13 on the orienting lug 2 connects with the material-holding chamber 14 on the expeller 9, and the top of expeller 9 is provided with the stock guide 10 on inclined-plane 11, and the inclined-plane 11 of stock guide 10 terminates in medial surface 12 tops of orienting lug 2.。

Blowing material pipe 8 is arranged on the orienting lug 2.Unit head 1 is a cylinder.

Screw is arranged in the guide groove 13 on the orienting lug 2 during work, and screw terminal is directed to the last plane of piece 2 and holds, and first screw 3 enters in the material-holding chamber 14 that is provided with on the expeller 9, and screw terminal is held by the last plane of expeller 9.Promote expeller 9 when the medial surface 12 of orienting lug 2 travels forward at cylinder 1, because expeller 9 is provided with the material-holding chamber 14 suitable with screw, and the material-holding chamber 14 on guide groove on the orienting lug 2 13 and the expeller 9 connects, so when expeller 9 when the medial surface 12 of orienting lug 2 travels forward, driving material-holding chamber 14 interior first screw 3 travels forward together, and the screws of the back being stayed in the guide groove 13 of orienting lug 2 stop, after the head of screw 3 is run into the inclined-plane 11 of stock guide 10 in the motion process, expeller 9 continues to move ahead, screw 3 is pushed blowing in the material pipe 8 of orienting lug 2 by the inclined-plane 11 of stock guide 10, finishes the sub-material action.
