Automatic discharging appearance inspection device for chip resistor production

Abstract

The invention discloses an automatic discharging appearance inspection device for chip resistor production, which comprises a working frame, a supporting plate is fixedly arranged at the bottom of one side of the working frame, a connecting column is fixedly arranged at one end of the top of one side of the working frame, and one side of the connecting column is fixedly connected with the middle part of one side of a discharging bin; a pressing rod connected with a material conveying pipe is connected with an acting wheel, the acting wheel is matched with a cam connected with a driving motor, a supporting column connected with the material conveying pipe is connected with an arc-shaped block, and the arc-shaped block is connected with a connecting spring in an arc-shaped cover; and a discharging motor on the discharging bin drives a discharging wheel and a rubber discharging plate connected with the discharging wheel, so that the appearance inspection device has an automatic discharging function, intermittent automatic discharging of single chip resistors can be performed during inspection, personnel inspection is more convenient, and the inspection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of chip resistor production, in particular to an appearance inspection device for chip resistor production with automatic discharge. Background technique [0002] As a kind of metal glass glaze resistor, chip resistor is also called chip fixed resistor. It is printed on the substrate by screen printing method. It has the characteristics of moisture resistance and small temperature coefficient, and can be greatly improved when used. Save circuit space cost. During the production of chip resistors, it is necessary to use an appearance inspection device to check the appearance of the chip resistors, so as to eliminate unqualified chip resistors. [0003] In view of this, Chinese Patent No. CN201610383971.8 proposes an appearance inspection device, which can obtain good performance in terms of inspection accuracy and inspection efficiency, and has excellent versatility, and can achieve effects such as miniaturi...

AI Technical Summary

Problems solved by technology

[0004] (1) The visual inspection device in the above patent does not have the function of automatic discharge. When performing visual inspection on chip resistors, due to the small size and large number of chip resistors, the device does not have the function of automatic discharge, so the device cannot be automatically discharged intermittently. Discharging, causing inconvenience for personnel to observe and affecting the working efficiency of the device;

[0005] (2) The appearance inspection device in the above patent does not have the material turning function. At present, when inspecting the chip resistor, personnel can only check it from the front. The lack of material turning function makes the device unable to turn over the chip resistor after the front inspection Inspection, which affects the inspection pass rate of the device and is not conducive to the use of personnel;

[0006] (3) The appearance inspection device in the above patent is not convenient for appearance inspection. Due to the small size of the chip resistor and the problem of external light, it is inconvenient for personnel to check, which affects the inspection and judgment of the personnel, and affects the pass rate of the chip resistor inspection.
