This study relates to an unbalance inspection device for the support of audio equipment (commonly known as rubber feet).

In detail, four are attached to the bottom of the audio device of the turntable so that the imbalance of rubber material (or spring included) to keep the device level while absorbing vibration of the device is placed on the flat surface. The present invention relates to a device for automatically checking whether or not the device is being made.

Conventionally, in order to check whether the support of the audio equipment set is level, the equipment set is placed on the surface and the edges are pressed by hand or the gap is visually inspected, and the gap is measured using a gauge. It was.

However, such a conventional inspection method is difficult to determine whether it is suitable for the reference value (within 0.5mm), it takes a lot of inspection time and there was also a non-scientific problem.

Therefore, there has been a need for an inspection apparatus capable of inspecting the imbalance of the support opening relatively precisely without an operator.

The purpose of this paper is to accurately and without humanity check the unbalance of the bases attached to the bottom of equipment sets that are continuously moved.

In order to achieve this purpose, two sets of sensors are installed on both sides of the central hole of the surface plate, and the surface plate detects the inlet imbalance detection device which is supported by the pedestal, and the entry and transfer of the product to a part of the existing conveyor system. A conveyor device comprising a sensor, and a set feeder configured to mount the mounting plate operated by the first cylinder as a second cylinder, and now the cylinder is moved back and forth horizontally as a third cylinder on the guide rod; It consists of a sensor and a control device that controls the operation of the cylinders. It is characterized by precise unmanned inspection of the unbalanced support of the base of the bottom of the device set by separately removing the device set in the middle of conveying the assembled device set as a conveyor.

According to the accompanying drawings in more detail as follows.

This proposal consists of an imbalance detection device (A), a conveyor device (B), a set feeder (C), and a control device (D) as a whole.

The imbalance detection device (a) has a structure in which the base 11 is supported by the pedestal 16 as shown in FIGS. 1 and 6, and a long hole 17 is formed in the center of the base 11, and the long hole ( Two sets of sensors (13) and (4) are installed in the 17, but the remaining sensors (3 ', 14') are installed to correspond to each other on the left and right sides, and these sensors (13, 13) (14) 14 'are fixed to the moving plate 12 to move as a motor (15).

Conveyor device (b) is a normal conveyor conveying line 18 and constitutes an entry detection sensor 19 for detecting the entry of the device set (A) at a predetermined position, and detects that the conveyed at a certain distance away The sensor 19 'may be comprised. The detection signal of this entry and transfer state activates the set feeder (C) input to the control device (D).

As shown in FIG. 1, the set feeder (C) is conveyed by connecting a piston (2 ") of the third cylinder (8), which is a hydraulic cylinder, to a feed plate (4) inserted in the guide rod (3) (3 '). The whole lifting device mounted on the plate 4 is moved forward and backward.

The lifting device comprises a lifting guide shaft (9) and a J-cylinder (1) on the conveying plate (4), the piston (2) is raised and lowered below the conveying plate (4), the set holder (5) on the piston (2) And the set holder 5 constitutes the first cylinder 6, 6 ', and the cylinder 6, 6' is provided with a mounting plate 7 connected to the piston 2 '.

The chordroll device (D) comprises a control circuit for sequentially controlling the hydraulic operation of the first, second, third cylinders (6) (6 '), (1) (8) of the wedge transfer device (C) and the sensor 103 According to the detection signals of the 13 ', 14, 14', 19 and 19 ', the operation of the cylinders 1, 6, 6' and 8 is controlled.

Notation: 20: equipment set bracket, 21: equipment set, 22: conveyor belt, 23: support, 24: support.

The present invention thus constructed will be explained by the operation schematic (FIG. 2) and the overall perspective view (FIG. 1).

First, when the switch of the control box (d) is pressed, the device set 21 is placed on the pedestal 20 by the stopper opening and entered on the belt conveyor 22. When a certain distance is entered, the stopper is closed and movement of the conveyor is temporarily stopped, and at the same time, the presence or absence of the device set 21 is checked by the photosensor 19. When it is confirmed that there is a machine set 21, the third cylinder (8) is moved up and down, the set holder (5) is lowered directly above the device set (21). The mounting plates 7 and 7 'are held by the first cylinders 6 and 6' with the set holder 5 lowered, and the J cylinder 1 with the device set 21 held therein. ), And the raised set holder 5 is moved above the surface plate 11 as the third cylinder 8. The set holder 5 is lowered as the J-cylinder 1 when it reaches above the surface plate 11, and when the device set 21 is placed on the surface plate 11, the sensors 13 and 13 'are driven by the driving of the motor 15. (14) (14 ') The moving plate 12 is moved slowly, and it detects whether the clearance gap between the support opening 24 and the surface of the surface plate 11 spreads beyond the predetermined space | interval.

If the gap measurement result is less than 0.5mm, it will operate normally and move the equipment set to the original position, but if it exceeds 0.5mm, it will be judged as bad and the buzzer will operate to inform the worker of the defect. The defective device set is reassembled and adjusted in the main assembly work line by the operator and then transferred.

As such, the present invention eliminates the hassle in the inspection process that a person manually presses an edge, visually inspects or measures using a gap measuring gauge, and reduces the use of manpower by automatically inspecting unattended. There is an advantage to this.
