The specific embodiment
The following stated is only preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
Embodiment, is shown in shown in Fig. 1, Fig. 2 a, Fig. 2 b: full-automatic refrigerator door sealing strip production line, comprise extruder, cutting machine, wear magnetic machine 21, bonding machine 30, manipulator 10 and transmit crawler belt, and bonding machine 30 includes mould 31.Concrete workflow is: extruder is extruded after sealing strip 200, and cutting machine is by sealing strip 200 section of being cut into shapes.Afterwards, manipulator 10 is carried to sealing strip 200 to wear magnetic machine 21, wears magnetic machine 21 magnetic stripe 100 is penetrated in sealing strip 200.Then, manipulator 10 is sent into sealing strip 200 in the mould 31 of bonding machine 30 and is welded.Finally, manipulator 10 takes out the sealing strip after welding fabrication 200 be placed into transmit on crawler belt and transfers out streamline.For the ease of sealing strip 200, enter in mould 31, full-automatic refrigerator door sealing strip production line includes 2 pairs pairs and grabs 41, and this 2 couple couple connects by variable pitch device between grabbing 41.Simultaneously, this 2 couple is two to be grabbed 41 and is promptly positioned at respectively behind the front-end and back-end of sealing strip 200 of bonding machine front end, and this variable pitch device starts, thus sealing strip 200 middle parts protuberances, there is the potential energy that moves forward into mould 31, and twoly grabbed 41 and guaranteed that the end of sealing strip 200 can perk.Like this, twoly grab 41 sealing strip 200 is sent in mould 31 accurately.
See shown in Fig. 3 a, Fig. 3 b: wear magnetic machine 21 and comprise and wear magnetic mouth 211, magnetic stripe displacement platform 212 and sealing strip fixed station 213.Wherein, magnetic stripe 100 penetrates in the sealing strip 200 being fixed on sealing strip fixed station 213 via magnetic stripe displacement platform 212.In order to limit the end of magnetic stripe 100, produce the displacement on above-below direction, the top of wearing magnetic mouth 211 is provided with magnetic conduction press strip 214.
See shown in Fig. 4 a, Fig. 4 b, Fig. 4 c, Fig. 4 d: sealing strip fixed station 213 places are provided with magnetic conduction pin 215.Concrete, magnetic conduction pin 215 is positioned at a side of entering magnetic stripe mouth of sealing strip 200, thereby this magnetic conduction pin 215 enters one of sealing strip 200 at magnetic stripe 100, stops, and a side of extruding magnetic stripe 100, makes magnetic stripe 100 reduce the free displacement on left and right directions.Meanwhile, the cross section of magnetic conduction pin 215 is less, and its free end can enter in sealing strip 200 in company with magnetic stripe 100.Magnetic conduction pin 215 can be connected with pneumatic member.When magnetic conduction pin 215 completes after once guiding task, under the effect of pneumatic member, can reset in time, ready for guide next time.
As shown in Figure 5, the upper lateral part of sealing strip fixed station 213 is provided with handgrip 216.These handgrip 216 compressing sealing strips 200 make it close contact in sealing strip fixed station 213, the displacement that restriction sealing strip 200 produces on above-below direction.Meanwhile, the inlet portion downside of sealing strip fixed station 213 is provided with negative pressure suction inlet 217.This negative pressure suction inlet 217 is closely attached on the magnetic stripe inlet portion of sealing strip 200 on sealing strip fixed station 213, and restriction sealing strip 200 produces free displacement.
As shown in Figure 6, mould 31 can be taked the mode of three partings.Concrete, mould 31 is positioned on bonding machine 30, this mould 31 comprises upper left mould 311, lower-left mould 312 and the right mould 313 cooperatively interacting, and the lower right side of upper left mould 311 is provided with upper left die cavity 3111, the upper right side of lower-left mould 312 is provided with lower-left die cavity 3121, and the left side central portion of right mould 313 is provided with right die cavity 3131.Like this, after upper left mould 311, lower-left mould 312 and right mould 313 close up, space and sealing strip 200 that upper left die cavity 3111, lower-left die cavity 3121, right die cavity 3131 surround match.That is, upper left mould 311, lower-left mould 312 and right mould 313 can separate, thereby have larger Robot actions space, are beneficial to the mould that enters of sealing strip 200.And sealing strip 200 enters after mould, upper left mould 311, lower-left mould 312 and right mould 313 close up.Accuracy when guaranteeing that upper left mould 311, lower-left mould 312 and right mould 313 close up, the right part upside of upper left mould 311 is provided with left tilted surface 3112, and the left upper portion of right mould 313 is provided with right tilted surface 3132, and left tilted surface 3112 and right tilted surface 3132 match.That is, when upper left mould 311, lower-left mould 312 and right mould 313 close up, left tilted surface 3112 and right tilted surface 3132 close contacts, thus guarantee that upper left mould 311, lower-left mould 312 are relative fixing with right mould 313 positions.
See shown in Fig. 7 a, Fig. 7 b: the place ahead that is positioned at mould 31 on bonding machine 30 is provided with guiding module 32.Obviously, guiding module 32 is divided into two parts, is respectively left guiding module 321 and right guiding module 322.Left guiding module 321 and right guiding module 322 can separate, and have respectively inner chamber.When left guiding module 321 and right guiding module 322 close up, their inner chamber forms the space of clamping sealing strip 200.Like this, sealing strip 200, under the clamping of manipulator 10, is first advanced in guiding module 32, and after manipulator 10 is withdrawn, sealing strip 200 is still subject to the clamping of guiding module 32, thereby can enter smoothly in mould 31.
As shown in Figure 8: because sealing strip 200 mostly is 4 head and the tail connections, weld, bonding machine 30 can be to be four angle welders.So-called four angle welders refer to workbench 34 and are provided with sealing strip geometrical clamp 33 and four bonding machines 30, and sealing strip geometrical clamp 33 and bonding machine 30 adjacent setting between two.Certainly, this bonding machine 30 includes mould 31.Sealing strip 200 is fixed on sealing bar geometrical clamp 33, and welds in mould 31.Adopt the advantage of four angle welders to be: 1) for a bonding machine 30, speed of welding has at least improved 4 times.And, without the position of multiple bearing sealing strip 200, speed of welding is further enhanced.2) welding quality is better.Four bonding machines 30 weld simultaneously, and the end of every sealing strip 200 is all subject to welding deformation simultaneously, avoided the situation of one end distortion, thereby welding quality are better.And only need carry out the location of once sealing bar 200, avoid locating time and again and the situation of sealing strip 200 change in location that cause has improved welding precision.
