When the clamp splice 2 is close to the translation block 3 downwards, the pinch roller 152 acts on the inclined plane of the pinch block 151, so that the pinch blocks 151 are far away from each other, space is reserved for the heat-shrinkable tube 16 to be flattened and clamped, the protruding part of the pinch block 151 stretches into the accommodating groove 21, the pinch block 151 is ensured not to interfere with the downward movement of the clamp splice 2, otherwise, when the clamp splice 2 is far away from the translation block 3 upwards, the pinch block 151 moves towards the middle to reset under the action of the spring IV 154, and the flat collapsed heat-shrinkable tube 16 is extruded, so that the heat-shrinkable tube 16 is restored, and the situation that the collapsed flat heat-shrinkable tube 16 is difficult to pass through a wire harness is avoided.
The working process and the principle thereof are as follows:
the coiled heat-shrinkable tube 16 is arranged on the unreeling wheel 13 for unreeling, and the unreeling wheel 13 maintains the tension of the heat-shrinkable tube 16 pulled by a tensioner. The heat shrinkage tube 16 passes through the space between the two limiting wheels 14 and then sequentially passes through the sleeve 521 and the through hole 31, so that the distance from the cutter II 9 to the tail end of the heat shrinkage tube 16 is equal to the required length.
The initial translation piece 3 is located leftmost, namely is far away from the position of clamping jaw 11, and sliding ring 43 at this moment is located horizontal segment one 611 leftmost, and clamp splice 2 is in the position that is close to translation piece 3 under the effect of spring one 45, and clamp splice 2 and translation piece 3 coaction make pyrocondensation pipe 16 press from both sides tightly between the two, all are equipped with the breach that holds pyrocondensation pipe 16 on clamp splice 2 and the translation piece 3, are convenient for pyrocondensation pipe 16 location. In addition, pinch roller 152 acts on the inclined surface of pinch blocks 151, so that two pinch blocks 151 are automatically far away from heat shrink tube 16, and spring four 154 is compressed.
When the output shaft of the air cylinder 51 extends, the translation block 3 moves rightward, namely moves to the clamping jaw 11, the clamping block 2 moves along with the movement, the slip ring 43 enters the horizontal section one 611, the clamping block 2 and the translation block 3 maintain a state of clamping the heat shrinkage tube 16, and the heat shrinkage tube 16 is pulled rightward from the unreeling wheel 13 for a certain distance along with the rightward movement of the translation block 3.
In the process, the pulley 93 is contacted with the protrusion 101 on the guide block 10, the protrusion 101 enables the pulley 93 to move upwards, the cutter II 9 moves upwards, the spring II 95 is compressed, the cutter II 9 and the cutter I8 act together, the heat-shrinkable tube 16 is cut off, the cut heat-shrinkable tube 16 and the end parts of the residual heat-shrinkable tube 16 are still in a clamped state, when the slip ring 43 moves to the rightmost end of the horizontal section and gradually slides upwards to enter the rising section 612, the clamping block 2 moves upwards along with the sliding block 3 and is far away from the translation block 3, the pinch roller 152 moves upwards along with the clamping block 2, the pinch block 151 starts to reset towards the middle heat-shrinkable tube 16 under the action of the spring IV 154, and in the reset process, the flat heat-shrinkable tube 16 which is originally clamped or sheared to be flat is extruded, and the extrusion direction is vertical to the clamping direction, so that the flat heat-shrinkable tube 16 can be pinched back to the original approximate round shape, and the wire harness cannot penetrate into the heat-shrinkable tube 16 from the end part of the flat heat-shrinkable tube 16.
The heat shrinkage tube 16 is in an unclamped state, at this time, the cut heat shrinkage tube 16 and the rest heat shrinkage tube 16 cannot move along with the movement of the translation block 3, and because the driven wheel 73 is at the highest point under the action of the spring III 77, the gap between the driving wheel 71 and the driven wheel 73 is larger, and the cut heat shrinkage tube 16 can smoothly enter between the driving wheel 71 and the driven wheel 73, and a part of the cut heat shrinkage tube is sleeved at the end of the wire harness.
As the translation block 3 continues to move rightward, the heat shrinkage tube 16 moves leftward relative to the sleeve 521, and the heat shrinkage tube 16 moves between the pinching blocks 151, and the pinching blocks 151 close to each other can squeeze other parts of the heat shrinkage tube 16 so that the heat shrinkage tube 16 returns to a circular shape. The sliding ring 43 is contacted with the unidirectional strip 63 and rotates upwards against the unidirectional strip 63, when the translation block 3 moves to the rightmost end, the sliding ring 43 is positioned at the rightmost end of the horizontal section II 613, the unidirectional strip 63 is reset under the action of the torsion spring 62, the pressing block 78 on the translation block 3 is contacted with the roller 74, the inclined surface of the pressing block 78 acts on the roller 74, the roller 74 moves downwards, the wheel frame 92 and the driven wheel 73 move downwards along with the sliding ring, the driven wheel 73 is close to the driving wheel 71, finally the heat shrink tube 16 is clamped between the driving wheel 71 and the driven wheel 73, the driving wheel 71 is driven by the motor 711 to rotate, the heat shrink tube 16 is driven to move rightwards, and therefore the end part of a wire harness penetrates out from the left end of the heat shrink tube 16, and the heat shrink tube 16 is prevented from being sleeved on a wiring terminal at the front end of the wire harness, and affecting the normal wiring function of the wire harness. When the heat shrinkage tube 16 touches the clamping jaw 11, the heat shrinkage tube 16 is blocked by the clamping jaw 11 and cannot move rightwards, and the air pipe 12 blows hot air of the hot air gun to the heat shrinkage tube 16, so that the heat shrinkage tube 16 is shrink-wrapped on the wire harness.
The sleeving operation of the heat shrinkage tube 16 is completed, the wire harness is taken down by the manipulator, a new wire harness is replaced for clamping by the clamping jaw 11, the output shaft of the air cylinder 51 is shortened, the translation block 3 is reset leftwards, the sliding ring 43 is always positioned on the horizontal section II 613 in the resetting process, the clamping block 2 is kept at the highest position, the new heat shrinkage tube 16 continuously moves rightwards from the sleeve 521 and finally passes through the through hole 31, when the sliding ring 43 moves to the top end of the vertical section 614, the clamping block 2 moves downwards again under the action of the spring I45 to clamp the heat shrinkage tube 16 between the clamping block 2 and the translation block 3, the length of the heat shrinkage tube 16 passing through the through hole 31 can be kept consistent because the distance of the left movement of the translation block 3 is the same each time, the cut heat shrinkage tube 16 is equal in length each time, the air cylinder 51 extends the output shaft again, and the operation is repeated, so that the sleeving operation of the heat shrinkage tube 16 at the next time can be realized.
It will be appreciated by those skilled in the art that the present invention can be carried out in other embodiments without departing from the spirit or essential characteristics thereof. Accordingly, the above disclosed embodiments are illustrative in all respects, and not exclusive. All changes that come within the scope of the invention or equivalents thereto are intended to be embraced therein.
