Room, the outer wall of capsule to be welded are fitted closely in the inner wall of the chamber.Start ultrasonic bonding program, is removed after the completion of welding
Ultrasonic bonding head takes out soldered capsule.
Embodiment 2
The present embodiment provides a kind of capsule welding method, using Pneumatic ultrasonic bonding machine (sea Rong Chaosheng in producer
Wave device Co., Ltd；Model DS300) with the use of the capsule welder in embodiment 1, ultrasonic wave is carried out to vibration capsule
Welding, capsule outer walls material are medical polycarbonate；Capsule diameter is 11mm；Length is 19mm.The knot of typical vibration capsule
Structure is as described in Chinese patent CN201620087784.0.
Welding process is as follows:
Set the parameter (such as amplitude, dwell time, delay time, ground connection time, energy, air pressure) of ultrasonic bonding machine
Afterwards, the capsule shell for preparing welding is assembled, is put into the second groove of welding pedestal, start ultrasonic bonding machine, ultrasonic wave
Plumb joint can move down automatically, and after the first groove and the second groove tight capsule, energy is conducted, and complete ultrasonic bond
Connect step.After the completion of welding, ultrasonic bonding head is removed, takes out welded capsule.
In conjunction with capsule welder of the invention, by regulation experiment repeatedly, the parameter setting of final optimization pass is as follows: amplitude

2.6kg。
One batch welds 1000 capsules, has welded three batches altogether, carries out leak water detdction, is detected yields and is respectively
93.6%, 92.8%, 94.5%.
And the yields of the ultrasonic bonding setting before optimizing is only 60% or so, therefore, using welding side of the invention
Method, capsule welding yields are greatly improved, and reduce production cost significantly.
During capsule Development of Welding, the inventors discovered that, different welding parameters has welding effect aobvious
Writing influences.For example, the intensity effect that different delay times welds capsule is significant, delay time, the too short soldering opening that will lead to was stitched
Gap has the gap, and delay time, there was abrasion on the too long capsule welding top that will lead to.
Fig. 4 is that (welding parameter: amplitude is set as 100%, the dwell time using welding method of the present embodiment after optimized
For 0.2s, delay time 0.5s, energy 100j), weld seam picture after the completion of welding, it can be seen from the figure that weld it is smooth,
Impulse- free robustness, and capsule welding top is without abrasion.
The welding result of (other parameters are same as above) when Fig. 5 shows that delay time is set as 0.3s, as can be seen from the figure
Capsule weld has clear gap, shows that welding effect is poor.
The welding result of (other parameters are same as above) when Fig. 6 shows that delay time is set as 0.7s, as can be seen from the figure
Though capsule weld has noticeable wear, influences the work of capsule device, welding effect without clear gap, capsule top
It is obvious poor.
Above embodiments are only exemplary embodiment of the present invention, are not used in the limitation present invention, protection scope of the present invention
It is defined by the claims.Those skilled in the art can within the spirit and scope of the present invention make respectively the present invention
Kind modification or equivalent replacement, this modification or equivalent replacement also should be regarded as being within the scope of the present invention.
