Description

An ultrasonic welding device that does not generate debris

technical field

The invention relates to the technical field of ultrasonic welding, in particular to an ultrasonic welding device that does not generate debris.

Background technique

The process of ultrasonic welding is to send ultrasonic waves to vibrate the upper and lower parts of the parts to be welded at a high speed, and the temperature of the contact parts rises rapidly to reach the melting point of the parts to be welded. So as to achieve perfect welding.

At room temperature, due to the high-speed vibration of the ultrasonic welding process, the parts to be welded will be slightly broken, resulting in welding debris. Welding debris is not allowed in the production of high-demand products such as medical equipment, precision electronic equipment, and chips. The welded products need to be strictly inspected, and unqualified products with debris are picked out.

At present, the existing ultrasonic welding equipment at home and abroad can not achieve no welding debris.

In order not to produce welding debris, products with high requirements for ultrasonic welding, such as medical equipment, precision electronics, and chips, often use softer plastics, so that no welding debris is generated during welding. However, the use of relatively hard plastics is also essential, so there is a need for a method that enables ultrasonic welding of hard plastics without welding debris.

The purpose of the present invention is to provide an ultrasonic welding device that does not generate debris in order to solve the shortcomings in the prior art.

In order to achieve the above object, the present invention adopts the following technical solutions:

An ultrasonic welding device that does not produce debris, comprising an ultrasonic welding machine and a temperature-controlled space, and specifically includes the following steps:

S1: First place the parts to be welded in a temperature-controlled space;

S2: heat up the welding and keep the temperature within a certain range;

S3: After the weldment reaches a specific range, ultrasonic welding is performed.

As a further solution of the present invention, the heating temperature of the weldment needs to be kept between 40°C and 60°C.

As a further solution of the present invention, in S3, the ultrasonic welding machine can be placed in a temperature-controlled space during welding.

As a further solution of the present invention, the ultrasonic welding machine part can be placed in a temperature-controlled space during welding in S3.

As a further solution of the present invention, the temperature of the temperature-controlled space is maintained within a certain range, and can be controlled by a program or a temperature controller.

As a further solution of the present invention, the temperature of the temperature-controlled space to be adjusted is different for the welding parts of different materials and different sizes.

Beneficial effects of the present invention:

1. In the present invention, since the brittleness of the workpiece to be welded rises to a certain temperature, its brittleness is reduced and its toughness is improved, and no welding debris is produced during ultrasonic welding.

2. The present invention fills in the blank that relatively hard plastics do not produce welding debris during ultrasonic welding, improves the welding stability of ultrasonic welding, and reduces the defect rate.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments.

Referring to Figure 1, an ultrasonic welding device that does not produce debris includes an ultrasonic welding machine and a temperature-controlled space, and specifically includes the following steps:

S1: First place the parts to be welded in a temperature-controlled space;

S2: heat up the welding and keep the temperature within a certain range;

S3: After the weldment reaches a specific range, ultrasonic welding is performed.

As a further solution of the present invention, the heating temperature of the weldment needs to be kept between 40°C and 60°C.

In the present invention, the ultrasonic welding machine can be placed in a temperature-controlled space during welding in S3.

Preferably, part of the ultrasonic welding machine can be placed in a temperature-controlled space during welding in S3.

Further, the temperature of the temperature-controlled space is maintained within a certain range and can be controlled by a program or a thermostat.

In the present invention, the temperature of the controlled temperature space adjusted by welding parts of different materials and different sizes is different.

The working principle of this embodiment: in actual use, the parts to be welded are first placed in a temperature-controlled space to keep the temperature within a certain range, and then ultrasonic welding is performed;

Or directly place the ultrasonic welding machine in a space with a controllable temperature, so that the workpiece to be welded is heated through the space with a controllable temperature, and then ultrasonic welding is performed;

Alternatively, the ultrasonic welding part is placed in a space with a controllable temperature, so that the parts to be welded are heated through the space with a controllable temperature, and then ultrasonic welding is performed.

Because the brittleness of the workpiece to be welded rises to a certain temperature, its brittleness is reduced and its toughness is improved, and no welding debris is produced during ultrasonic welding.

A temperature-controlled space, whose temperature is maintained within a certain range, can be controlled by a program or a thermostat. Different materials and different sizes of parts to be welded, adjust the temperature of the controllable temperature space to be different.
