Description

Automatic labeling device for AC contactor

technical field

The invention relates to a device for pasting labels on an AC contactor, in particular to an automatic labeling device for an AC contactor.

Background technique

Contactor is a widely used automatic control electrical appliance, mainly used for frequently connected or disconnected AC and DC circuits. It has the advantages of large control capacity and long-distance operation. Cooperating with relays, it can realize functions such as timing operation, interlock control, various quantitative controls, voltage loss and undervoltage protection, and is widely used in automatic control circuits. Strict quality inspection must be carried out when the AC contactor leaves the factory. After the parameters of the inspection are qualified, a label is pasted. The label contains information such as the trademark, product specification model, technical parameters, and date of manufacture. At present, the method of pasting labels on AC contactors still adopts automatic assembly line, manual pasting operation, low work efficiency and high labor intensity for workers.

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing:

As shown in Fig. 1 combined with Fig. 2 and Fig. 3, an automatic labeling device for an AC contactor includes a frame 1 and a belt conveyor 2, the belt conveyor 2 passes through the frame 1, and at least one side of the belt conveyor 2 is installed with Baseband retracting device, guide wheel 3 and pressing device 4, described baseband retracting device is made up of take-up roller 5, storage tape roller 6 and stepper motor 7, and storage tape roller 6 is made up of stepper motor 7 Drive, roll the base tape 9 pasted with the label 8 on the tape storage roller 6, the label 8 is continuously pasted on the smooth surface of the base tape 9 by self-adhesive, a label separation wheel 10 is provided on the conveyor road frame of the belt conveyor device 2, and the base tape One end of 9 is coiled on the take-up roller 5 after the guide wheel 3, the label separation wheel 10 and the guide wheel 3, and the outside of the label separation wheel 10 is fixed with a pressing device 4 and an optical fiber sensor 11, and the label 8 is placed on the label separation wheel 10. The place is separated from the base belt 9 and extends to the AC contactor 12. Since the rotation angle at the label separation wheel 10 is small, under the action of the tension of the label 8 itself, the label 8 is automatically opened, and when the AC contactor 12 passes through the label separation wheel 10, the back of the label 8 contacts the side of the AC contactor 12, Utilize the viscosity of the self-adhesive on the back of the label 8 to be automatically pasted on the side of the AC contactor 12, and be pressed by the pressing device 4. At the same time, the optical fiber sensor 11 senses the signal passing through the AC contactor 12 and makes the stepping motor 7 rotate for a certain period of time. angle, and then make the take-up roller 5 roll the base tape 9 of a certain length, and the next label 8 stretches out to realize continuous pasting. The present invention can paste the label 8 automatically, saves manpower, has high work efficiency, and sticks the label 8 firmly.

The take-up roller 5, the guide wheel 3 and the stepper motor 7 are installed on the workbench 13, and the workbench 13 is connected with the lifting mechanism; the storage roller 6 is installed on the storage roller shaft 14 and can be adjusted up and down, The storage roll wheel shaft 14 is fixed on the frame 1. The height of the workbench 13 can be adjusted through the lifting mechanism, so as to adapt to the position where the label 8 is pasted.

Described elevating mechanism is made up of leading screw 15, screw nut 16 and guide rod 17, and screw nut 16 is fixed on the workbench 13, and leading screw 15 and guide rod 17 are installed on the frame 1, and rotation leading screw 15 can make work Station 3 is raised or lowered.

There are two sets of the base tape retractable device, the guide wheel 3 , the pressing device 4 , the label separation wheel 10 , the workbench 3 and the lifting mechanism, which are symmetrically distributed on both sides of the belt conveying device 2 . Two sets of sticking devices can be used to stick different labels 8 to the two surfaces of the AC contactor 12 at the same time.

The pressing device 4 is a brush. The brush has a certain degree of elasticity, which imitates the action of sticking the label 8 firmly with the brush manually, so that the label 8 is stuck firmly.

The input side of the belt conveyor 2 is provided with a positioning block 18, a photoelectric sensor 19 and a shield clamping mechanism 20. The positioning block 18 is driven by a cylinder and can swing back and forth at 90° on the conveyor belt to block the AC contact. The device 12 is positioned still and lets the AC contactor 12 pass through. The shield clamping mechanism 20 is made up of clamping plates 21 driven by two cylinders. The clamping plates 21 correspond to the shields of the AC contactor 12. The device can automatically clamp the shield of the AC contactor 12, has a simple structure and high working efficiency.

A side wall of the conveyor belt slideway of the belt conveying device 2 is provided with an arc-shaped guiding guardrail 22, the AC contactor 12 contacts the guiding guardrail 22 during the conveying process, and the AC contactor 12 follows the circular arc of the guiding guardrail 22. Friction turns 90°. Since the shield of the AC contactor 12 needs to be positioned at both sides of the belt conveyer 2 when the shield is clamped, and the AC contactor 12 must be rotated 90° to be pasted when the label 8 is pasted, the AC contactor 12 touches the guide guardrail 22 Finally, it still moves forward under the action of the belt conveyor 2. At this time, there is a certain friction force between the AC contactor 12 and the guide guardrail 22, and the AC contactor 12 moves forward along the arc of the guide guardrail 22 while moving forward. Rotate, and enter the linear slideway after turning 90°, realize the self-rotation of the AC contactor 12 in the conveying process, save manpower, and have a high degree of automation.
