Abstract
The utility model discloses an anti-missed-welding device, relating to an auxiliary device for spot welding equipment. The anti-missed-welding device comprises a power supply, a welding spot counter, a PLC (Programmable Logic Controller), a relay, an electromagnetic valve and a clamp opening switch, wherein the power supply is connected with the welding spot counter, the PLC controller and the relay; and the output end of the welding spot counter is connected with an input terminal of the PLC, an output terminal of the PLC is connected with the relay, the output end of the relay is connected with the input end of the electromagnetic valve, and the output end of the electromagnetic valve is connected with the clamping opening switch. According to the utility model, the PLC cannot control a gas circuit to be in a gas introduction state through the electromagnetic valve until the number of welding spots, counted by the welding spot counter, surely reaches the number of set welding spots, at the moment, the clamping opening switch is started to normally open a clamp, the workpiece can be taken out to enter the next working procedure, and the therefore, missed welding of welding spots caused by personnel factors can be thoroughly and effectively prevented; and the anti-missed-welding device has the characteristics of simple structure and low cost and is easy to popularize and use.
Description
Technical field
The utility model relates to a kind of servicing unit of spot-welding equipment, particularly a kind of seal weld device.
Background technology
In auto parts and components are produced, because welding screw, the nut of auto parts and components assembly are more, when adopting manual spot welding; Though indicated the quantity of solder joint on the technical papers,, caused influencing product quality owing to reasons such as the operative employee is unskilled or absent minded cause Lou weldering solder joint through regular meeting; Generation is done over again or is reprocessed; And in a single day these underproof products come into the market, and also can receive client's complaint and claim, and the reputation to enterprise also can cause bad influence simultaneously.
Summary of the invention
The technical problem that the utility model will solve is: a kind of seal weld device that can prevent the leak-stopping weldering is provided, to solve owing to leaking the above-mentioned weak point that weldering causes.
The technical scheme that solves the problems of the technologies described above is: a kind of seal weld device; This device comprises power supply, solder joint counter, PLC controller, relay, magnetic valve and anchor clamps unlatching switch; Described power supply is connected with solder joint counter, PLC controller and relay respectively; The output of solder joint counter is connected with the input terminal of PLC controller; The lead-out terminal of PLC controller is connected with relay, and the output of relay is connected with the input of magnetic valve, and the output of magnetic valve is opened switch with anchor clamps and is connected.
The further technical scheme of the utility model is: described magnetic valve is an air-operated solenoid valve, and it is that air-actuated jaw is opened switch that described anchor clamps are opened switch.
The further technical scheme of the utility model is: described relay is an auxiliary reclay.
Because adopt said structure, the seal weld device tool of the utility model compared with prior art has following beneficial effect:
1, can prevent effectively that solder joint from leaking weldering:
Because the seal weld device of the utility model comprises power supply, solder joint counter, PLC controller, relay, magnetic valve and anchor clamps and opens switch; Wherein the PLC controller can be controlled the through and off of gas circuit through magnetic valve; When the solder joint number of counting when the solder joint counter did not reach the quantity of setting, the PLC controller can be controlled gas circuit through magnetic valve and be in off-state, opened switch even start anchor clamps this moment; Anchor clamps also can't be opened, and workpiece also can't be removed; Must accomplish the number of welds of setting when the solder joint number that the solder joint counter is counted really; When not having the weldering of leakage; Just control gas circuit through magnetic valve is in aeration status to the PLC controller, starts anchor clamps this moment and opens switch, and anchor clamps could normally be opened; Workpiece could take out and flow to subsequent processing, thereby can prevent effectively thoroughly that the solder joint that causes because of human factor from leaking weldering.
2, simple in structure, cost is low.
The utility model relatively simple for structure just increases by one and can control the magnetic valve that anchor clamps are opened switch on the basis of existing spot-welding equipment, its cost is lower, is easy to promote the use of.
Below, in conjunction with accompanying drawing and embodiment the technical characterictic of the seal weld device of the utility model is further described.
Description of drawings
Fig. 1: the schematic block circuit diagram of the seal weld device of the utility model,
In above-mentioned accompanying drawing, each piece mark is explained as follows:
The 1-power supply, 2-solder joint counter, the 3-PLC controller, the 4-relay,
The 5-magnetic valve, the 6-anchor clamps are opened switch.
The specific embodiment
Embodiment one:
Disclosed among Fig. 1 is a kind of seal weld device; This device comprises power supply 1, solder joint counter 2, PLC controller 3, relay 4, magnetic valve 5 and anchor clamps unlatching switch 6; Described power supply 1 is connected with solder joint counter 2, PLC controller 3 and relay 4 respectively; The output of solder joint counter 2 is connected with the input terminal of PLC controller 3, and the lead-out terminal of PLC controller 3 is connected with relay 4, and described relay 4 is an auxiliary reclay; The output of this relay 4 is connected with the input of magnetic valve 5, and the output of magnetic valve 5 is opened switch 6 with anchor clamps and is connected; Above-mentioned magnetic valve 5 is an air-operated solenoid valve, and anchor clamps are opened switch 6 and opened switch for air-actuated jaw.
The operation principle of the utility model is following:
When 2 in solder joint counter count solder joint number when not reaching the quantity of setting, PLC controller 3 can be controlled gas circuit through magnetic valve and be in off-state, opens switch even start anchor clamps this moment, anchor clamps also can't be opened, workpiece also can't be removed; Must when 2 in solder joint counter count the solder joint number accomplish the number of welds of setting really; When not having the weldering of leakage; Just control gas circuit through magnetic valve 5 is in aeration status to PLC controller 3, starts anchor clamps this moment and opens switch 6, and anchor clamps could normally be opened; Workpiece could take out and flow to subsequent processing, thereby can prevent effectively thoroughly that the solder joint that causes because of human factor from leaking weldering.
