Technical Field

The invention mainly relates to the field of ultrasonic welding, in particular to an ultrasonic welding process of a plastic reel for packaging electronic components, which is only suitable for being applied to special plastic reels which need to be formed by ultrasonic welding in the industry needing electronic component packaging materials.

Background

The process is completed by welding two injection molded semi-finished products by using positioning ultrasonic waves in the electronic component packaging material industry. The process is a complete set of plastic reel ultrasonic welding method which is automatically designed, put into use and improved by the engineers of our company under the condition of meeting the client conditions. The traditional ultrasonic welding has the same core technology, low efficiency and low fault tolerance rate.

The conventional ultrasonic welding technique is to transmit a high-frequency vibration wave to the surfaces of two objects to be welded, and to fuse molecular layers formed by rubbing the surfaces of the two objects against each other under pressure. The technique is widely used for welding thermoplastic plastics, processing fabrics and films. The ultrasonic welding system mainly comprises an ultrasonic generator, a transducer/amplitude transformer/welding head three-link group, a mould and a frame.

The method has the following defects: 1. the product placement position needs to be adjusted manually in the welding process, and the welding mould of the traditional welding machine is not accurate enough in positioning;

2. the ultrasonic noise has certain damage to human ears.

The published Chinese invention patent, application number CN201611142426.6, patent name: the utility model provides a charger upper cover and inferior valve ultrasonic welding device, application day: 2016-12-13, the invention relates to an ultrasonic welding device for an upper cover and a lower cover of a charger, which comprises a workbench (1), wherein an ultrasonic machine 2 and a linear guide rail (3) positioned on the front side of the ultrasonic machine are arranged on the workbench (1), and an automatic clamping device (4) is movably connected onto the linear guide rail (3); the ultrasonic machine (2) consists of a machine body (21) and a welding upper die (22); the method is characterized in that: a welding lower die (5) corresponding to the upper welding die (22) is arranged under the upper welding die (22) of the workbench (1); an infrared inductor (6) is arranged on the right side of the lower welding die (5); the automatic clamping device (4) sends the workpiece (10) into the lower welding die (5), the infrared sensor (6) senses the workpiece, and the upper welding die (21) is pressed down to be matched with the lower welding die (5) to finish welding. The invention has the advantages of high automation degree, good reliability, saved operation process, shortened operation time and further improved production efficiency.
