Abstract
The utility model discloses an antiskid stopper for press fit of circuit boards, which comprises an upper stopper and a lower stopper. The technical scheme mainly includes that one end of the upper stopper is hinged with one end of the lower stopper, the lower stopper is fixed onto a bottom plate, an elastic device capable of spreading the upper stopper is arranged between the upper stopper and the lower stopper, and the elastic device can be a spring and the like. Two ends of the lower stopper are fixed onto the bottom plate by dowels, and the periphery of the upper end surface of the upper stopper is filleted. Accordingly, lower pressure of a hot pressing plate can not directly act on the antiskid stopper due to contraction of the spring when multiple layers of circuit boards are in press fit, damage to the thermal compression plate is avoided, simultaneously the multiple layers of circuit boards have better thermal pressure bearing capacity, and production yield is improved. Simultaneously, emergency processing of the antiskid stopper is extremely convenient as when the dowel is broken, only the broken part of the dowel needs to be tapped out to replace a new dowel.
Description
[technical field]
The utility model relates to the anti-skidding block of a kind of circuit board pressing.
[background technology]
In the process of board production, multi-layer sheet is because the needs of production procedure need to use mirror steel plate to carry out the pressing of HTHP.Do not produce the mirror steel plate slippage between the multilayer circuit board because of pressure makes greatly for guaranteeing in the pressing process, the situation that the multi-layer sheet that causes can't normally bond takes place, and needs to increase anti-skidding block this moment and prevents slip between the circuit board.Existing anti-skidding block is that a block plate block directly is fixed on the chassis by screw, can directly play the effect that prevents that circuit board from sliding like this.But in actual production process the height of circuit board pressing might not, when the height of its pressing is lower than the steel plate block, the hot dish of press will directly be pressed on the steel plate block, and steel plate around be the right angle, give the hot pressing dribbling serious damage.Because multilayer circuit board can't be subjected to enough pressure, cause cohesive force not enough simultaneously, directly cause multilayer circuit board to be scrapped.Brought very big loss to production like this.And use screw to connect, its intensity is little, the loosening easily or fracture of screw.During screw extraction, breaking portion can be stayed in the screw, be difficult for to take out, and the screw that often needs the mode by tapping again to renew is given and produced bigger trouble.
[utility model content]
The purpose of this utility model provides the anti-skidding block of a kind of circuit board pressing, and this anti-skidding block can avoid the thermal pressure of hot pressing dish directly to damage the hot pressing dish on the anti-skidding block of effect, reduces the scrappage of board production, and is connected on the chassis more easily.
In order to address the above problem, the utility model by the following technical solutions:
The anti-skidding block of a kind of circuit board pressing, comprise block and following block, it is characterized in that: an end of an end of described upward block and described block down is hinged, and following block is fixed on the chassis, is provided with the elastic device that block is launched between last block and following block.
The anti-skidding block of aforesaid circuit board pressing is characterized in that described elastic device is a spring.
The anti-skidding block of aforesaid circuit board pressing, it is characterized in that two ends at described down block by dowel fixes on the chassis.
The anti-skidding block of aforesaid circuit board pressing is characterized in that the described equal rounding all around of going up the block upper surface.
The beneficial effects of the utility model have: after adopting said apparatus; elastic device shrinks in the process that the hot pressing dish presses down, and thermal pressure can not act directly on the block, has played the effect of protection hot pressing dish; and equal rounding around the last block upper surface has further avoided the hot pressing adjustment debit to hinder.Adopted the pin connection simultaneously, improved bonding strength, even the pin fracture, breaking portion also can be pounded out easily.So both protect the equipment of producing, improved the yield of producing again.
[description of drawings]
The utility model is described in further detail below in conjunction with accompanying drawing and concrete execution mode;
Fig. 1 is the stereogram of a kind of execution mode of the utility model;
Fig. 2 is the right view of the utility model user mode;
[embodiment]
As shown in Figure 1, the anti-skidding block of a kind of circuit board pressing, comprise block 1 and following block 2, it is characterized in that: an end of an end of described upward block 1 and described block 2 down is hinged, following block 2 is fixed on the chassis 5, is provided with the elastic device that block 1 is launched between last block 1 and following block 2.Described elastic device 3 can be spring and also can be torsion spring.
The described two ends of block 2 down are fixed on the chassis 5 by pin 4.Increased time block 2 like this and tried to get to the heart of a matter 5 bonding strength,, breaking portion need have been pounded out and to get final product even when pin ruptures.
The described equal rounding all around of going up block 1 upper surface is in the time of can avoiding hot pressing dish 7 to contact with the upper surface of last block 1 like this, owing to corner angle damage hot pressing dish 7.
During use, multilayer circuit board 6 abuts against down a side of block 2, and hot pressing dish 7 presses down Shi Xianyu and goes up the contact of block 1 upper surface, and spring 3 begins to shrink, and reaction force is little.When anti-skidding block is compressed to multilayer circuit board 6 highly quite, hot pressing dish 7 beginning pressing multilayer circuit boards 6.Following block 2 is fixed on the chassis 5 by pin 4, and multilayer circuit board 6 can not produce slide relative between the circuit board in the process of pressing.
