Embodiment 1

[0035] Such as figure 1 As shown, the embodiment of the present invention provides a weld detection device, the device includes:

[0036] The laser 1 is used to emit a line laser, and make the line laser vertically incident on the weld seam of the object to be welded, so as to form a laser line along the weld seam;

[0037] Specifically, the laser 1 refers to a device capable of emitting laser light. According to the working medium, lasers can be divided into several categories: gas lasers, solid-state lasers, semiconductor lasers and dye lasers. Free electron lasers 1 have also been developed recently, and high-power lasers 1 are usually pulsed outputs. The pure quality and stable spectrum of light emitted by the laser 1 can be applied in many ways. The original lasers 1 were rubies excited by bright flash bulbs, producing a "pulsed laser" rather than a continuous steady beam. The quality of the speed of light produced by this laser 1 is essentially different from the las...

Embodiment 2

[0051] Such as figure 2 As shown, the present invention provides a weld detection method, which can be applied to the weld detection device described in Embodiment 1, and the method includes:

[0052] Step 110: emit a line laser through the laser, so that the line laser is incident on the weld seam of the object to be welded, and form a laser line along the weld seam;

[0053] Specifically, the laser emits laser light, which is incident on the welding seam of the workpiece, and a laser line is formed between the workpiece and the laser.

[0054] Step 120: Control the image collector to collect the first image including the laser line based on the first preset exposure time; obtain the first straight line based on the first image through the control device; further, the first preset exposure The time is 1 / 2700~1 / 3300s.

[0055] Specifically, the first image is obtained by turning on the laser, turning off the light source, and reducing the exposure time of the image collecto...

Abstract

The invention discloses a welding seam detection device and method. The device includes: a laser device for emitting line laser light, and making the line laser light vertically incident on the weld seam of an object to be welded to form a laser line; a light emitting device, The light-emitting device is arranged on one side of the laser, and is used to emit a light beam, and make the light beam incident on the weld seam of the object to be welded; an image collector, the image collector is arranged on the laser On the other side, it is used to collect a first image including the laser line based on a first preset exposure time, and collect a second image of the weld under the irradiation of the beam based on a second preset exposure time. Through the present invention, the technical problems of low welding efficiency and poor accuracy of the existing welding technology are effectively solved, and the accuracy of weld detection is achieved, the welding efficiency and precision are improved, the integrity, reliability and safety of the weld are improved, and the welding seam is reduced. Little resource waste, cost-saving technical effect.
