Problems solved by technology

The peeling treatment not only increases the operation process, but also increases the processing cost
[0006] 2. If the special enameled wire is used to wind the coil winding in order to avoid the process of removing the varnish of the lead wire, the cost will increase because the special enameled wire is more expensive than the ordinary enameled wire
[0007] 3. Manual lead-tin welding operation, the accumulation height of solder joints is not easy to control, which will lead to non-standard and inconsistent lead welding, which will affect the pass rate of lead welding
[0008] 4. The fluxes and cleaning agents required for lead-tin soldering are all chemicals, and their use will undoubtedly cause environmental pollution

Abstract

An application of spot welding technique to the down-lead connection of slice vibrant electrical loop winding, including the welding of the down-lead and double-faced PCB board. This invention does not need welding materials and plumbum; the enamel wire welding does not need pre-removing enamel cover and stannum soaking pre-processing, and reduces the industrial pollution caused by using lacquer removing solution and welding assistant. This invention uses half-mechanization of electronic spot welding machine, avoids the weak points of the hand welding operation, and effectively prevent of bad contact phenomenon. Therefore, this invention not only reduces the cost, but also improves the working efficiency and greatly increases the eligible ratio of the welding.

Description

【Technical field】 [0001] The invention relates to the application of the electronic spot welding process, in particular to the application of the electronic spot welding process to the connection of the lead wires of the coil windings of the chip vibration motor. 【technical background】 [0002] Chip vibration motor is also called button or coin vibration motor. It is mainly used in vibration and silent alarms of mobile phones or beauty appliances such as massagers, massage cushions, vibrating massage sticks, etc. [0003] Chip vibration motor is a kind of DC motor, including: brush chip vibration motor and brushless chip vibration motor. The rotor of the brushed vibrating motor is a coil winding, and the stator of the brushless vibrating motor is a coil winding. [0004] In order to meet the flat structure requirements of the chip vibration motor, both the coil windings of the rotor and the coil windings of the stator are arranged in a plane, and are composed of 2 to 4 hol...
