Description

TECHNICAL FIELD

[0001] The utility model belongs to semiconductor welding equipment technical field, especially related to a 90 degree angle coaxial light and bar light composite industrial vision light source. BACKGROUND

[0002] After the clip is punched from the clip frame (clip strip) in the mold, the clip array is sucked out by the suction nozzle, and the position and angle accuracy of each clip of the clip array sucked by the suction nozzle are detected by the upward-looking vision system, and whether the suction is missed is detected by vision.

[0003] In addition to the high-performance camera and lens required by the industrial vision system, a good light source system support is also needed. Because the number of clips (clips) on the suction nozzle is generally large, the field of view of the camera lens is relatively large. It is difficult for ordinary light sources to achieve ideal imaging effects. That is, it is difficult to avoid uneven brightness in the camera field of view, and the clip edge and background gray value cannot achieve the effect of clear light and shade, resulting in unclear clip edge recognition.

[0004] After searching, in the prior art, Chinese patent publication No. CN215569988U, published on January 18, 2022, discloses an industrial vision light source, which comprises a reflecting guard plate, the reflecting guard plate is embedded on the lamp holder, and the reflecting guard plate reflects the light emitted by the bulb; the adjusting assembly is embedded with the reflecting guard plate, and the adjusting assembly controls the opening and closing state of the reflecting guard plate; the above embodiment can adjust the opening and closing of the reflecting guard plate, so as to achieve the purpose of gathering and dispersing the light, thereby controlling the strength of the light, and the power consumption of the bulb in the two forms is equal, which has good energy-saving effect.

[0005] However, the device still has the following defects:

[0006] If the ideal lighting effect is to be achieved, a light source with a large emitting area must be used, which will result in an increase in the space of the machine, an increase in cost, and an insufficiently compact structure of the machine. It is difficult for each standard model of light source purchased on the market to achieve the ideal lighting effect under the premise of small space and compactness. INVENTION CONTENTS
