Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the invention and therefore show only the structures which are relevant to the invention.
First embodiment as shown in fig. 1 to 9, the present embodiment provides a kick-out mechanism, which includes a positioning seat 1, a kick-out head 2, an alarm trigger 3 and a locking assembly 4. The positioning seat 1 is suitable for positioning the stirring head 2. The stirring head 2 is arranged on the positioning seat 1, specifically, the stirring head 2 is arranged on the inner side of the bottom of the positioning seat 1, and the stirring head 2 is rotationally connected with the positioning seat 1. The alarm trigger piece 3 is arranged on one side of the stirring head 2, and the alarm trigger piece 3 is in sliding connection with the stirring head 2. The entire stirring head 2 can be axially stretched. The stirring head 2 is linked with the alarm trigger piece 3. The locking component 4 is arranged on the inner side of the positioning seat 1, the locking component 4 is positioned above the stirring head 2, one end of the locking component 4 is in butt joint with the stirring head 2, and the locking component 4 is suitable for stretching along the length direction of the positioning seat 1. Specifically, in this embodiment, the workpiece is a frame for placing a plurality of chips, and a plurality of through grooves are formed on the side edges of the frame, and the diameters of the through grooves correspond to the diameters of the stirring heads 2.
The stirring head 2 is used for feeding the workpiece, and as the side edge of the workpiece is provided with the circular through grooves, when feeding and subsequent conveying are performed, the stirring head 2 can be inserted into the groove of the workpiece from the upper part and push the workpiece to move by a station distance, then the stirring head 2 is lifted and reset, and then is vertically inserted into the next groove on the workpiece, so that the effects of feeding and conveying the workpiece are realized. When it needs to be described, the above situation is that the workpiece is in a correct position, and the workpiece is manually placed at the feeding end of the device in the actual feeding process, so that the workpiece may have a situation that the placement position is inaccurate, that is, an offset state, in this case, the stirring head 2 cannot be correctly inserted into a groove of the workpiece, but is abutted with a long surface of the workpiece, at this time, the stirring head 2 is driven by the positioning seat 1 to not reach a maximum stroke, the workpiece pushes the stirring head 2 to retract, then the stirring head 2 pushes the alarm triggering member 3, so that the alarm triggering member 3 slides radially along one side of the stirring head 2 to abut against the positioning seat 1 and pushes the positioning seat 1, and because the positioning seat 1 is relatively fixed, that is, the stirring head 2 is kept stationary relative to the stirring head 2, and is rotationally connected with the positioning seat 1, when the alarm triggering member 3 abuts against the positioning seat 1, the stirring head 2 is reversely pushed by the positioning seat 1 along with the continuous extension of the alarm triggering member 3 toward the direction of the positioning seat 1, so that the stirring head 2 is far away from the positioning seat 1 in the direction of the connection of the positioning seat 1. When the stirring head 2 rotates beyond a specific angle, the stirring head 2 can be clamped by the locking component 4, and the locking component 4 tightly holds and positions the stirring head 2. At this time, the material stirring head 2 deflects and can not continuously stir the material, so as to remind an operator of wrong placing position of the workpiece.
The structure of the stirring head 2 is specifically described below, and the stirring head 2 includes a rotary cap 21 and a step plug 22. The top of the rotating cap 21 is rotationally connected with the positioning seat 1, a sliding cavity 11 is formed in the positioning seat 1, one end of the stepping plug 22 is inserted into the sliding cavity 11, and the other end extends out of the bottom of the sliding cavity 11. Through the arrangement, the rotating cap 21 can drive the stepping plug 22 to synchronously rotate around the joint of the rotating cap 21 and the positioning seat 1, meanwhile, the stepping plug 22 can also independently slide in the sliding cavity 11, and the whole stepping plug 22 presents a combined movement of sliding and rotation. Furthermore, one end of the alarm trigger 3 is also inserted into the sliding chamber 11 and is located at the top of the sliding chamber 11. The rotation direction of the connection between the rotary cap 21 and the positioning seat 1 is perpendicular to the conveying direction of the workpiece. When the placing position of the workpiece is correct, the stepping plug 22 is inserted into a groove of the workpiece to push the workpiece to horizontally step by one station; when the position of the workpiece is offset, the stepping plug 22 is abutted against the upper surface of the workpiece, and the workpiece pushes the stepping plug 22 to slide upwards along the sliding cavity 11, so that the stepping plug 22 pushes the alarm trigger piece 3 to extend outwards along the radial direction of the stepping plug 22. Through the arrangement, if the workpiece is placed correctly, the positioning seat 1 drives the stepping plug 22 to be inserted into the groove of the workpiece, if the workpiece is placed offset, the positioning seat 1 drives the stepping plug 22 to be abutted against the upper surface of the workpiece, the workpiece further pushes the stepping plug 22 to retract into the rotating cap 21, and slides along the sliding cavity 11 to be abutted against the alarm triggering piece 3, then pushes the alarm triggering piece 3 to slide to the outer side of the sliding cavity 11, and after the alarm triggering piece 3 is abutted against the positioning seat 1, the positioning seat 1 pushes the rotating cap 21 to drive the stepping plug 22 to reversely rotate along with the continuous outward sliding of the alarm triggering piece 3.
In order to realize the effect of correctly driving the alarm trigger piece 3 to slide, a trigger hole 12 is formed in one side of the sliding cavity 11, and the alarm trigger piece 3 is slidably arranged in the trigger hole 12. Meanwhile, an inclined surface 31 is formed at one end of the alarm triggering member 3 facing the sliding cavity 11, and the inclined surface 31 is arranged facing the step plug 22. Through the arrangement, in the process that the step plug 22 is retracted into the sliding cavity 11, the step plug 22 can be abutted against the inclined surface 31 of the alarm trigger piece 3, and the alarm trigger piece 3 slides outwards along the trigger hole 12 along with the step plug 22 pushing the inclined surface 31, and one side of the positioning seat 1, which is close to the alarm trigger piece 3, is integrally provided with the limiting block 13. The positioning seat 1 extends to the lower part of the alarm triggering piece 3 from one side through the limiting block 13, so that when the alarm triggering piece 3 extends outwards, the positioning seat can be abutted with the limiting block 13, and the limiting block 13 pushes the rotating cap 21 to drive the stepping plug 22 to rotate.
In order to enable the rotating cap 21 to rotate correctly, the height of the trigger hole 12 is lower than the height of the joint of the rotating cap 21 and the positioning seat 1. Through the arrangement, when the alarm trigger piece 3 is abutted with the limiting block 13, the limiting block 13 can push the alarm trigger piece 3, so that the rotating cap 21 drives the stepping plug 22 to rotate in a direction away from the limiting block 13.
In order to achieve the effect that the locking assembly 4 locks the rotating cap 21 after the rotating cap 21 is rotated to a certain angle, the locking assembly 4 includes a locking spring 41 and a locking block 42. The inner side of the positioning seat 1 is provided with a locking groove 14, the locking block 42 is slidably arranged in the locking groove 14, and the locking block 42 is abutted with the top of the rotating cap 21. The locking spring 41 has one end connected to the top wall of the locking groove 14 and the other end connected to the locking block 42. The locking spring 41 is kept in a compressed state so that the locking piece 42 is driven by the elastic force of the locking spring 41 to keep a state of being held in abutment with the rotating cap 21, regardless of whether the rotating cap 21 is rotated or by how much. On the basis, when the rotating cap 21 rotates to a specific angle, the locking block 42 can clamp the rotating cap 21 from the upper side, the effect of locking the rotating cap 21 is achieved, after the rotating cap 21 is locked, the stepping plug 22 is inclined relative to a workpiece due to the fact that the stepping plug rotates along with the rotating cap 21, meanwhile, the pressing force between the end portion of the stepping plug 22 and the workpiece is greatly reduced, the stepping plug 22 enters an alarm state at the moment, the workpiece cannot be stirred, an operator is required to adjust the position of the workpiece at the moment, and the stepping plug 22 is reset manually.
In order to achieve the effect of locking the rotary cap 21 by the locking block 42 in the above process, two sides of the top end of the rotary cap 21 are arc surfaces, an arc groove 421 is formed in one side of the locking block 42 facing the rotary cap 21, and the arc groove 421 is arranged along the sliding direction of the locking block 42. The circular arc groove 421 corresponds to the circular arc surface of the rotary cap 21. When the rotating cap 21 slides until the center of the circular arc surface completely coincides with the circular arc groove 421, the rotating cap 21 reaches the specific rotation angle mentioned above, and the circular arc groove 421 clamps the circular arc surface, so that the locking effect of the locking block 42 on the rotating cap 21 is achieved.
In order to achieve the effect of resetting the step plug 22 in the sliding cavity 11, a first reset spring 15 is disposed in the sliding cavity 11, one end of the first reset spring 15 is connected with the top wall of the sliding cavity 11, and the other end is connected with the top wall of the step plug 22. After the step plug 22 is retracted into the sliding cavity 11, the step plug 22 can be pushed to reset outwards by the first reset spring 15.
In order to achieve the effect that the alarm trigger piece 3 resets along the trigger hole 12, a second reset spring 32 is sleeved outside the alarm trigger piece 3, one end of the second reset spring 32 is connected with the outer wall of the rotary cap 21, and the other end of the second reset spring is connected with the outside of the alarm trigger piece 3. After the step plug 22 is reset, the second reset spring 32 can pull the alarm trigger 3 to retract the alarm trigger 3 into the sliding cavity 11 along the trigger hole 12.
In addition, it should be noted that, when the workpiece is placed, the offset is difficult to avoid, and when the offset is small, it is unnecessary to make the step plug 22 enter the alarm state, so the material stirring mechanism in this embodiment further has a repairing effect, specifically, the inner wall of the sliding cavity 11 is provided with the spiral groove 16, and one side of the step plug 22 is provided with the guide post 23. The guide posts 23 are disposed within the helical groove 16, and the guide posts 23 correspond to the helical groove 16. In this embodiment, the positioning seat 1 swings from one side of the workpiece to the slot inserted into the workpiece, so that the step plug 22 will gradually rotate along one side to the slot inserted into the workpiece or one side abuts against the upper surface of the workpiece during the process of the positioning seat 1 driving the step plug 22 to swing. In this state, the workpiece pushes the step plug 22 to retract into the sliding cavity 11, at this time, the step plug 22 slides along the spiral groove 16 through the guide post 23, so that the step plug 22 also rotates helically, at this time, the step plug 22 pushes the workpiece forward through rotation, in most cases, the offset of workpiece placement is smaller, the step plug 22 can push the workpiece forward, so that the step plug 22 falls into the next groove of the workpiece, and when the step plug 22 rotates to the position where the stroke of the spiral groove 16 is maximum, the step plug 22 pushes the workpiece forward distance also reaches the position where the step plug 22 still cannot be inserted into the groove of the workpiece, i.e., the step plug 22 enters an alarm state.
