Preferably, the pulling force of pull bar is big when buffering the precompression of stage clip than parallel clipping grips maximum electronic component 5%-10%, so when normal patch is inserted, will not because load increase and causing buffer spring to be further compressed makes parallel folder Hold the rising of formula chuck.

As depicted in figs. 1 and 2, the invention also discloses a kind of according to parallel clamp-type large-sized electronic component as described above Patch inserts the patch insert method of operation head, comprises the following steps：

1）, sticking and inserting machine determine wait pasting on slotting station after each elaborate position of the element on pcb board, loader or material Disk will treat that the slotting electronic element 8 of patch is sent to the position of patch plug clamping element, and sticking and inserting machine is by parallel clamp-type large-sized electronics Element patch inserts the driving of operation head to waiting to paste above slotting electronic element, is acted by controlled motor 27 so that driven pulley two 611 rotate, so as to drive hub splines 1, splined shaft 10, hub splines 2 12, parallel clipping chuck 9, pull bar 13 successively Rotated in the horizontal direction around the axis of splined shaft 10 with the upper circle of thrust bearing 15, parallel clipping chuck is rotated to greatly The reasonable clamping direction of type electronic component, then acted by controlled motor 1 so that the timing belt one of synchronous belt device one 211 drive L-type sliding blocks 4 move down, so as to drive clamping cylinder 5, pull bar adapter sleeve 14, pull bar 13, splined shaft 10, hub splines two 12 move down together with parallel clipping chuck 9；

2）, control clamping cylinder 5 piston rod action, by pull bar 13 control parallel clipping chuck 9 be in clamp shape State, so as to clamp electronic element 8 using parallel clipping chuck 9；

3）, acted again by controlled motor 1 so that the timing belt 1 of synchronous belt device one drives L-type sliding block 4 Move up, so as to drive parallel clipping chuck 9 to move up, using parallel clipping chuck 9 by electronic element 8 from loader or Picked up in person's charging tray, when above moving on to certain altitude, the parallel clamp-type large-sized electronic component patch of sticking and inserting machine driving is inserted operation head and moved The camera and light source assembly installed in sticking and inserting machine table top were moved, under the electronic element 8 picked up from parallel clipping chuck Side takes pictures to the electronic element 8, and sticking and inserting machine is according to the electronic component ground plan picture of acquisition and carries out graph image Processing, the deviation of the position and direction of electronic component pin and direction and the slotting status requirement of patch is analyzed, is calculated each straight After the angle value that shift value and electronic the element needs of angular coordinate kinematic axis rotate, acted again by controlled motor 27, Control parallel clipping chuck 9 to rotate again to be adjusted parallel clipping chuck corner, when in parallel clipping chuck When electronic element angle is consistent with the electronic component angle required on pcb board, driven by sticking and inserting machine parallel clipping big Type electronic component patch inserts the movement of operation head so that the electronic component in parallel clipping chuck is located at the top of station to be pasted；

4）, pass through controlled motor 1 and act so that parallel clipping chuck 9 drives electronic element 8 to move down together, When in the hole that patch slot is put on the pin insertion pcb board of the lower section of electronic element, the piston rod of control clamping cylinder 5 moves Make, control parallel clipping chuck 9 to be in open configuration by pull bar 13, so that parallel clipping chuck 9 is unclamped to big The clamping of type electronic component 8, then acted by controlled motor 1 so that parallel clipping chuck 9 moves up, and completes one large-scale The patch of electronic component 8 is inserted；

When completion the 4th）After step, execution the 1st is gone to）Step carries out patch to next electronic element 8 and inserted, until complete Patch into all electronic elements 8 is inserted.

Parallel clamp-type large-sized electronic component patch inserts the end effector mechanism that operation head is sticking and inserting machine, and sticking and inserting machine makes to pass through phase Machine finds the mark points on pcb board, so that it is determined that waiting to paste each element elaborate position on pcb board on slotting station well.

Described 1st）Step and the 3rd）Parallel clipping chuck rotation is acted by controlled motor 27 in step, successively Drive the driven pulley 2 611 of synchronous belt device two, lower ring body 24, hub splines 1, splined shaft 10, hub splines 2 12, flat The upper circle of the clipping chuck 9 of row, pull bar 13 and thrust bearing 15 rotates to realize together.

Described 2nd）It is the piston by controlling clamping cylinder 5 to control parallel clipping chuck to be in clamped condition in step Bar shrinks, and drives pull bar adapter sleeve 14, thrust bearing 15, pull bar 13 and chuck sliding block 35 to move up, when chuck sliding block 35 is to moving up When dynamic, left V-type gripping block 26 is driven to be rotated around the pin joint of left V-type gripping block 26 and chuck bearing 25 by left connecting rod 28 And drive right V-type gripping block 27 to be rotated around the pin joint of right V-type gripping block 27 and chuck bearing 25 by right connecting rod 29, So as to promote left plate formula clamping jaw 30 that right V is moved and utilized along clamping jaw moving leader 32 using one end of left V-type gripping block 26 One end of type gripping block 27 promotes right flat clamping jaw 31 to be moved along clamping jaw moving leader 32 so that left plate formula clamping jaw 30 and the right side Flat clamping jaw 31 gradually is drawn close to realize, when parallel clipping chuck 9 is in clamped condition, positioned at left plate formula clamping jaw Reseting pressuring spring 1 between 30 and right flat clamping jaw 31 can be compressed, in compressive state；

Described 4th）It is the piston by controlling clamping cylinder 5 to control parallel clipping chuck to be in open configuration in step Bar stretches out, and under the restoring force effect of reseting pressuring spring 1, left plate formula clamping jaw 30 and right flat clamping jaw 31 move along clamping jaw Guide rod 32 moves to realize towards the direction being located remotely from each other.

To sum up, electronic element can quickly and accurately be pasted and is inserted on pcb board by the present invention, improve the patch of sticking and inserting machine Insert speed, patch inserts precision and operating efficiency.The present invention is by structure design, lifting that can accurately to parallel clipping chuck Process, rotary course and clamping process are controlled, and the patch for further increasing electronic element inserts precision.Pushed away by setting The structure that power bearing, pull bar, pull bar adapter sleeve and clamping cylinder piston rod are engaged so that parallel clipping chuck is clamping electricity It will not change the state clamped because of the angle rotation of parallel clipping chuck during subcomponent.By setting chuck sliding block, connecting Extension bar, V-type gripping block are engaged with flat clamping jaw, so as to conveniently to the clamped condition of parallel clipping chuck and Releasing orientation is controlled.By setting upper and lower spacing ring on splined shaft and by setting buffering stage clip and parallel clamping Formula chuck coordinates, and can to work as during patch is inserted, when causing to paste the shock of plug appearance from top to bottom due to certain error, The electronic component for ensureing to clamp on parallel clipping chuck will not drop automatically, also will not be due to impact from the bottom up be present And destroy patch plug.

Above example is used for illustrative purposes only, rather than limitation of the present invention, the technology people about technical field Member without departing from the spirit and scope of the present invention, can also make a variety of changes or convert, therefore all equivalent Technical scheme should also belong to protection scope of the present invention, and protection scope of the present invention should be limited by each claim.
