Description

Technical Field

[0001] The invention relates to a screw material dividing mechanism. Background Art

[0002] Screws are indispensable parts in most assemblies. In order to cooperate with the automation of the assembly process, screws are required to be able to automatically divide materials. In the prior art, there are mechanisms to achieve screw dividing. However, in actual application, most of them get stuck. Analysis shows that the main reasons for the jamming are: one is that when the centrifugal vibrator sorts the screws, it is common that the nut of the rear screw is overlapped with the nut of the front screw until it is pushed to the feed chute, causing the dividing push block at the dividing position to act on the two overlapping workpieces at the same time, causing it to get stuck on the material transfer channel; the other is that when the screws are not arranged vertically in the feed chute for some reason, the push block does not have the function of straightening the screw, causing the tip of the screw to get stuck on the wall of the feed chute, affecting the dividing.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Reference Figure 1-Figure 6As shown, a screw material distributing mechanism in this embodiment comprises: a base 1, a guide cover plate 2, a guide baffle plate 3 and a power device 4 that provides reciprocating power for the guide baffle plate 3; a baffle plate slot 11 for flexibly mounting the guide baffle plate 3 is provided on the base 1, a material feeding slot 12 is provided on one side of the baffle plate slot 11 on the base 1, the material feeding slot 12 is perpendicular to the baffle plate slot 11, a material blanking through hole 13 is vertically provided on the other side of the baffle plate slot 11 on the base 1, and the material blanking through hole 13 partially overlaps the baffle plate slot 11 to form a material passing port 1 31, the material passing port 131 is aligned with the material feeding trough 12; a guide port 31 for blocking and pushing materials is beveled on the guide baffle 3, and a baffle 311 is formed after milling on the bevel of the guide port 31 for blocking materials; a pusher head 312 is formed after milling on the lower 1 / 2 of the plane of the guide port 31 for pushing materials; a guide cover plate 2 is fixedly installed above the base 1, and a power device 4 is installed on one end of the base 1 through a mounting plate 41, and a power output shaft of the power device 4 is connected to the extension ear 32 of the guide baffle 3.

[0023] The guide cover plate 2 is provided with a feed channel 21 and a blanking hole 22. The feed channel 21 is aligned with the feed trough 12 and extends to the blanking hole 13. The blanking hole 22 is aligned with the blanking hole 13. The upper edge of the blanking hole 22 is chamfered. The push head 312 is a pointed cone.

[0024] Preferably, the depth of the baffle groove 11 and the feed groove 12 is equal to the height of the guide baffle 3; the aperture of the blanking through hole 13 is slightly larger than the outer diameter of the nut of the workpiece screw; the power device 4 can be cylinder power or motor screw power.

[0025] Refer to the following Figure 1-Figure 6 The action process of the fabric folding mechanism is described in detail: first, the workpiece is sent to the feed channel 12 of the material distribution mechanism by an external centrifugal vibrator. At this time, the guide baffle 3 is in the reset position, and the workpiece is transported to the place to be distributed and blocked by the baffle 311. Then the guide baffle 3 is pushed forward to cause the pusher head 312 to act on the workpieces outside the place to be distributed to isolate them, and at the same time act on the workpieces at the place to be distributed (because the action surface of the pusher head is an inclined surface and a pointed cone, combined with the feed channel and the blanking hole on the guide cover plate, it can straighten the workpiece screws and push the workpiece) into the blanking through hole to complete the distribution; then the guide baffle 3 is reset, and the isolated workpiece is transported to the place to be distributed to complete another operation.

[0026] A screw dividing mechanism of the present invention realizes reciprocating motion by opening a linear baffle groove on a base and equipping it with a guide baffle for reciprocating movement, and the simple action ensures the stability of the mechanism; by beveling the guide opening on the guide baffle and milling a baffle and a push head on the guide opening, and then cooperating with a guide cover plate, the baffle on the guide baffle has a material blocking function when resetting, and the push head of the guide baffle has the function of separating the waiting screws and straightening them when pushing, and pushing the blanking screws into the blanking through hole to complete the material dividing; the dividing mechanism designed in this way can stably convey the screws and accurately divide the screws without jamming.
