Problems solved by technology

However, in actual use, it is found that during detection, the detection beam may directly pass through the observation channel 180 on the margin of the material tray, especially in the case of a small amount of material tape, resulting in the fact that there is actually a material tray but the controller displays In the case of no tray, the accuracy of the above-mentioned detection device still needs to be improved

Embodiment 1

[0026] An embodiment of the present invention provides an SMT tray detection assembly, including a transmitter 20 located on one side of the tray 1 and emitting a detection beam to it, and a receiver located on the other side of the tray 1 and adapted to the transmitter 20 21. The connection line between the transmitting end of the transmitter 20 and the receiving end of the receiver 21 runs through the tray 1 obliquely; the detection beam is a monochromatic light with a wavelength smaller than the wavelength of the green light. 1 is cut off, the receiver 21 cannot receive the detection beam, and then will send a material signal to the controller; when a transparent material tray 1 is put in, since the detection beam is monochromatic light with a wavelength smaller than the wavelength of green light, the wavelength is short and the penetrating ability Poor, and it adopts the method of oblique irradiation. After the detection beam is irradiated on the tray 1, it will be greatly ...

Embodiment 2

[0035] The embodiment of the present invention provides an SMT tray detection component, the same as the first embodiment will not be repeated, the difference is:

[0036] Such as Figure 4 As shown, the connection line between the transmitting end of the transmitter 20 and the receiving end of the receiver 21 only runs through the bobbin 11 of the tray 1 .

[0037] Preferably, the angle between the line connecting the transmitting end of the transmitter 20 and the receiving end of the receiver 21 and the bobbin 11 on the tray 1 is not less than 30° and not greater than 60°.

Abstract

The invention relates to an SMT charging tray detection assembly which comprises an emitter and a receiver, wherein the emitter is positioned on one side of a charging tray and emits a detection light beam to the charging tray, and the receiver is positioned on the other side of the charging tray and is matched with the emitter; a connecting line of the emitter transmitting end and the receiver receiving end obliquely penetrates through the charging tray; the detection light beam is monochromatic light with the wavelength less than that of the green light; the purpose that the receiver cannot receive the detection light beam due to the fact that the detection light beam enters the charging tray and the detection light beam are greatly attenuated is achieved, the detection accuracy cannot be affected by an allowance observation through groove and the allowance of a material belt, and the detection accuracy is greatly improved.

Description

technical field [0001] The invention relates to the technical field of tray detection, and more specifically, to an SMT tray detection component. Background technique [0002] The material tray is a common auxiliary tool for unwinding the material tape. Figure 5 and Figure 6 These are two common reels. The reel 1 specifically includes a bobbin 11 around which the feed tape is wound, and two bobbins 12 fixed to both ends of the bobbin 11 respectively; The main disc body 13 connecting the outer annular ring 10 and the bobbin 11; the main disc body 13 is often provided with a margin observation slot 180 . [0003] Before production, workers need to know the storage situation of the tray on the tray rack to determine whether the remaining amount can meet the production demand. Since the inventory of trays on the tray rack is dynamically changing, it is necessary to continuously track the inventory of trays on the tray rack so that workers can replenish materials in time. ...
