Problems solved by technology

There are some problems in this production method: 1. The sewing method can see the sewing thread and processed traces from the outside, which will affect the appearance of high-end products such as smart watches that the watch is paired with
2. The sewing method can only sew around the hook surface belt, and cannot process the entire surface of the hook surface belt. The strength is poor and the life of the watch strap is short

Embodiment Construction

[0022] Now in conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail.

[0023] see Figure 1 to Figure 3 , figure 1 It is a schematic diagram of the laser processing method and device of the present invention. figure 2 It is a schematic diagram of the wristband of the present invention before welding the hook surface band. image 3 It is a schematic diagram of the wristband of the present invention after welding the upper hook surface. The present invention proposes a processing method for a watch strap, which includes a watch strap body 9 and a suede strap 7 and a hook strap 8 arranged on the strap body 9 . The strap body 9 is made of plastic. The suede strap 7 is attached to the first part of the surface of the strap body 9 . The hook strap 8 is attached to the second surface of the strap body 9 . Wherein, the hook surface band 8 is laser-transmissive. In this embodiment, the surface of the second pa...

Abstract

The invention provides a watchband and a machining method and device thereof. According to the method, a plastic watchband body and a hook face band allowing lasers to transmit are adopted, and the face, making contact with the watchband body, of the hook face band is subjected to contactless welding machining through laser beams formed by a laser device, thus, the quality of the watchband can be greatly improved, and the service life of the overall watchband can be prolonged.

Description

technical field [0001] The invention relates to the field of laser welding of plastics, and is especially suitable for laser welding of watch straps that can freely adjust the tightness of the Velcro according to the size of the arm. Background technique [0002] Since the advantages of laser plastic welding are less resin degradation, less debris, non-contact welding process will not cause secondary pollution, and laser welding has less mechanical and thermal stress than other connection methods, so now plastic welding has Laser welding is widely used. [0003] At present, the laser welding of thermoplastics adopts the principle of transmission welding, that is, the two parts to be welded are overlapped and placed together, one of the two parts can pass through the laser while the other part must absorb the laser, and then form on the contact surface (welding area) of the two parts. Heat action zone: the plastic in the heat action zone is melted, and the plastic macromolec...
