Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description:
As Fig. 1 to Fig. 4, shown in Figure 7, promotional component on a kind of SMT of the being used for frock clamp that provides for the utility model, comprise the connector 1 that is connected with the SMT frock clamp, and the distribution 2 that is slidingly matched of described connector 1 and be located at described connector 1 and promote shell fragment 3 between 2, an end of described shell fragment 3 relies on described connector 1, the other end relies in the described distribution 2.
Described distribution 2 has sliding tray 21, and the width of described sliding tray 21 can move around by described relatively connector 1 described distribution 2 greater than the width of described connector 1.Here the width of saying is meant sliding tray 2] transverse width and the transverse width of promoting 2, promote 2 when sliding into two ends, the sidewall of sliding tray 21 is promoted 2 during against described connector 1 and can't be continued to slide.
The other end of described shell fragment 3 relies on the bottom of described sliding tray 21.Moving around and move around in the bottom of sliding tray 21 relatively with described sliding tray 21.The two ends of shell fragment 3 lean connector 1 respectively and promote 2, and the pressure of 2 clinching pcb boards is promoted in permanently effective maintenance, are not subject to temperatures involved and reduce the elasticity downforce.
From Fig. 7, be installed on the frock clamp cutaway view as can be seen, described connector 1 is connected with described SMT frock clamp by bolt 4, described bolt 4 passes described connector 1 and shell fragment 3, and described connector 1 and shell fragment 3 together are fixed on the described SMT frock clamp.One end of shell fragment 3 has the through hole that described bolt 4 is passed, and an end of shell fragment 3 is stepped up between the pallet 5 of connector 1 and frock clamp, and the other end, as shown in Figure 1 and Figure 2, then elastic top leans against the bottom of sliding tray 21.The structure of sliding tray makes and promotes clinching, promoting when triping pcb board to slide gets final product, easy to operate.
As shown in Figure 3, the front end of described distribution 2 has a pressure section 22 that extends.Pressure section 22 is the clinching pcb board better, and the bottom surface of pressure section 22 is a lozenges, can slip on the pcb board more smoothly and the disengagement pcb board.Can not cause the situations such as scuffing of pcb board.
As shown in Figure 4, described shell fragment 3 adopts stainless steel material to make, and described shell fragment 3 is a bending structure, and bending angle is spent between 30 degree 10, and the bending angle in the present embodiment is 20 degree.
In further change scheme, the quantity of described shell fragment 3 is two, and described two shell fragments 3 are fixedly connected on the described SMT frock by bolt 4 with the two ends of described connector 1 respectively.The power that the elastic force of two shell fragments can guarantee to promote the clinching pcb board better, more firm.
Except that above-mentioned providing drives the promotional component, the utility model also provides the SMT frock clamp that above-mentioned promotional component is installed, extremely shown in Figure 7 as Fig. 5, comprise the pallet 5 that is used to lay pcb board, described pallet 5 has the upper surface mounting groove 6 concordant with its upper surface that makes pcb board, mounting groove 6 is mainly used in pcb board and is placed on the pallet 5, according to different pcb board model, dimensional requirements, the shape of mounting groove 6 is also done corresponding modify, this part is a known technology, and not inventive point of the present utility model place, no longer it is given unnecessary details here.
As Fig. 5, shown in Figure 7, have groove 51 on the body of described pallet 5, described promotional component is installed in the described groove 51, and the upper surface of described connector 1 is lower than the upper surface of described pallet 5 or concordant with the upper surface of described pallet 5.The side that described groove 51 is corresponding with laying pcb board is a breach 52, the front end of described distribution 2 and described breach 52 are corresponding and stretch out or enter described groove 51 with moving of described distribution 2, be arranged in the described distribution 2 of described groove 51, its upper surface is lower than the upper surface of described pallet 5 or concordant with the upper surface of described pallet 5.The position of breach 52 is corresponding with pcb board, after pcb board is in place, moves and promotes 2 like this, and the front end of distribution 2 stretches out from breach 52, and then clinching is on pcb board.In the present embodiment, as shown in Figure 5, have 8 grooves on the body of pallet 5, promotional component all is installed in each groove.It is more even that 8 promotional component that diverse location distributes are distributed button pressing force, more firm to the clinching of pcb board, be difficult for rocking.
As shown in Figure 7, described connector 1 is installed in the described groove 51, specifically be connector two ends by bolt pass the back be connected with a fixed by nut.Being placed in the described groove 51 of described distribution 2 activities can move around in groove 51, and described connector 1 is arranged in the sliding tray 21 of described distribution 2, promotes 2 positions of sliding by connector 1 restriction, and prevents that it from deviating from from groove 51.
After the upper surface of above-mentioned said pallet 5 is meant and places pcb board in the pallet 5, the surface concordant with the upper surface of pcb board.In order to make promotional component its upper surface before not having the clinching pcb board not be higher than the surface of pcb board, printing process is not impacted, require connector 1 and promote the upper surface that 2 upper surface is not higher than pallet, just be lower than or flush in the upper surface of pallet 5.In printing process, can not lean the steel mesh on the pcb board like this, the formation space influences printing process between steel mesh and the pcb board thereby make.And because distribution its upper surface when not pushing down pcb board is lower than or flushes in the upper surface of pallet 5, the upper surface of connector 1 also is lower than or flushes in the upper surface of pallet 5, so pcb board can not be affected when printing.Can realize printing, paster, reflow process shared of pcb board, save dismounting, installation in each operation, efficient is able to remarkable lifting.
