Background
On the production line of the white welding process of the automobile, the quality of the welding electrode end face of the spot welding robot directly influences the welding strength. In order to ensure the welding quality of the welded product, the electrode cap of the welding electrode is usually replaced after a certain number of welding points are welded. When the electrode cap is taken off from the front end of the welding gun, electrode cooling water flows out from the front end of the welding gun, and normal use of peripheral equipment is affected.
The invention patent with the patent number ZL201811300702.6 discloses a cooling water anti-falling device which can prevent cooling water from flowing out of the front end of a welding gun when an electrode cap is detached. Specifically, as shown in fig. 5, before the replacement of each electrode attached to the tip of the welding torch, the circulation of the cooling water in each electrode 3 is stopped by the shutoff valve 11, and a part or all of the cooling water stored in the cooling water passage 41 is sucked into the interior of the cylindrical body 5, so that when each electrode 3 is detached from the tip of the welding torch 2, the cooling water can be prevented from flowing out from the tip of the welding torch. After a new electrode 3 is attached to the tip of the welding gun, the stop of the cooling water circulation by the stop valve 11 is released, and spot welding by the spot welding machine is enabled. The defect of the scheme is that after the electrode cap is detached, if the power supply system is suddenly powered off, the water absorption function of the cooling water anti-falling device is disabled, and cooling water flows out from the front end of the welding gun.

As shown in fig. 1-2, the water manager provided by the present invention includes a welding gun cooling water inlet pipe 11, a welding gun cooling water return pipe 24 and a water storage device 3, wherein a water outlet end of the welding gun cooling water inlet pipe 11 is used for connecting with a water inlet interface of a welding gun, a water inlet end of the welding gun cooling water return pipe 24 is used for connecting with a water return interface of the welding gun, and the welding gun cooling water inlet pipe 11 is provided with a two-position two-way normally-off solenoid valve 4.
The water storage device 3 comprises a connecting rod 31, a water cylinder 32, a cylinder 33 and a two-position five-way electromagnetic valve 34, the water cylinder comprises a cylinder body, a piston and a piston rod, one side of the piston of the water cylinder is connected with the piston rod, the other side of the piston of the water cylinder and the inner wall of the cylinder body form a water containing cavity 320, the water containing cavity 320 is communicated with the welding gun cooling water return pipe 24 through a pipeline, the piston rod of the water cylinder 32 and the piston rod of the 33 cylinder are fixedly connected with the connecting rod 31 respectively, a first working interface of the two-position five-way electromagnetic valve 34 is communicated with a rod cavity 331 of the cylinder 33 through a pipeline, a second working interface of the two-position five-way electromagnetic valve 34 is communicated with a rodless cavity 332 of the cylinder through a pipeline, and an air source interface of the two-position five-way electromagnetic valve 34 is used for connecting an air source. Wherein, the cylinder can adopt a double-acting cylinder. The number of the cylinders may be one, two, or more than two. The selection may be made according to the actual situation, and is not particularly limited herein.
The two-position, five-way solenoid valve 34 is an automated basic element for controlling fluid. Specifically, a technically mature two-position five-way single electric control solenoid valve or a two-position five-way double electric control solenoid valve may be adopted. The two-position five-way double-electric control solenoid valve is provided with two working interfaces, an air source interface and two air outlets.
Referring to fig. 3 and 4, when the coil B of the two-position five-way dual-electric control solenoid valve is powered on, air is supplied to the rodless cavity 332 of the cylinder through the air source interface and the second working interface, the piston rod of the cylinder 33 moves to the left to drive the piston rod of the water cylinder 32 to move to the left, so that the water containing cavity 320 of the water cylinder 32 generates negative pressure, and cooling water remaining in the welding gun cooling water return pipe 24 and the welding gun cooling water inlet pipe 11 is sucked into the water containing cavity 320, so that when the electrode cap is detached from the front end of the welding gun, the cooling water can be prevented from flowing out from the front end of the welding gun. Two position five-way two electric control solenoid valve have the function that the outage kept, and at this moment, if the power supply system outage, two position five-way two electric control solenoid valve's coil A and coil B lose the electricity simultaneously, and water storage device 3's jar 32 can keep the state of drawing water before the outage.

At this time, if the power supply system is powered off, the water tank 32 of the water storage device 3 can be kept in a water pumping state before the power supply system is powered off because the coil of the two-position five-way single electric control electromagnetic valve is originally not powered on. The water in the water containing cavity 320 cannot return to the cooling water return pipe of the welding gun, so that the cooling water can be still effectively prevented from flowing out from the front end of the welding gun.
When the coil of the two-position five-way single electric control electromagnetic valve is electrified, air is supplied to the rod cavity 331 of the air cylinder 33 through the air source interface and the first working interface, the piston rod of the air cylinder 33 moves towards the right side to drive the piston rod of the water cylinder 32 to move towards the right side, and cooling water flows back to the welding gun cooling water return pipe 24 and is stored in the water containing cavity 320 of the water cylinder.
