Embodiment
A lot of details have been set forth in the following description so that make much of the present invention.But the present invention can implement much to be different from alternate manner described here, and those skilled in the art can do similar popularization under the situation of intension of the present invention, so the present invention does not receive the restriction of following disclosed practical implementation.
Secondly, the present invention utilizes sketch map to be described in detail, and when the embodiment of the invention was detailed, for ease of explanation, said sketch map was an instance, and it should not limit the scope of the present invention's protection at this.
Do detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention.
As shown in Figure 1, the anti-heavy locking device of bonding machine provided by the invention comprises pressing element system and briquetting system, and said pressing element system is the both sides of one group of symmetrical structure and said briquetting system.
Said pressing element system comprises pressing element base 1, pressing element cylinder 3, pressing plate mounting platform 4 and pressing element spring 2; Said pressing element cylinder 3 is fixed on the said pressing element base 1; Said pressing plate mounting platform 4 is fixed on the pressing element cylinder 3; When pressing element cylinder 3 moves both vertically, then drive the pressing plate mounting platform and move up and down with 4 the time, said pressing element spring 2 is positioned at the both sides of pressing element cylinder 3, and the two ends of pressing element spring 2 are individually fixed on pressing element cylinder 3 and the pressing element base 1; Motion amplitude in order to control pressing element cylinder 3 prevents that hyperacoustic disappearance is to guarantee bonding quality in the bonding technology process.
In the said pressing element system pressure plate structure is housed also; Corresponding to the symmetrical structure of pressing element system, on two pressing plate mounting platforms 4 pressure plate structure is housed respectively, as shown in Figure 2; Said pressure plate structure comprises pressing plate 12 and paw 13; Pressing plate 12 is provided with adjustable hole slot so that be fixed on the pressing plate mounting platform 4 according to the position needs, and pressing plate 12 belows are fixed with paw 13, and bonding jumper that said paw 13 is many finger-shaped constitutes so that the framework of pressing encapsulation article better; Pressing plate 12 on the both sides pressing plate mounting platform 4, paw 13, shape can adjust according to the specific product demand, said pressure plate structure along with the interlock effect of pressing element cylinder 3 up and down pressing with open.
