[0002] With the wide application of robot welding automation in all walks of life, welding spatter will be generated during the welding process of the welding torch. When the spatter reaches a certain degree, it will affect the subsequent welding quality. Therefore, a gun cleaner is needed to clean the spatter on the inner wall of the welding torch, so as to ensure the subsequent welding quality. Under this background, gun cleaning equipment has emerged. At present, there are two gun cleaning methods on the market, one is the reamer type and the other is the sandblasting type.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present utility model.

[0022] Please refer to Figure 1-2 , the present utility model provides a technical solution: a rotary sandblasting gun cleaning device, including: a frame body; a sandblaster 01, a sprayer 02 and a wire cutter 10 are arranged on the top of the frame body, a vibrating screen 06, a sand replenishing port channel 07, an air tank 16, a sand supply hopper 08 and a waste sand recycling bin 15 are respectively arranged inside the frame body. The discharge port of the sandblaster 01 is communicated with the feed port of the vibrating screen 06, the output end of the vibrating screen 06 is communicated with the inlet of the sand supply hopper 08, the sand replenishing port channel 07 is communicated with the inlet of the sand supply hopper 08, the waste discharge end of the vibrating screen 06 is communicated with the waste sand recycling bin 15, the air inlet of the air tank 16 is externally connected to compressed air, and the air outlet of the air tank 16 is respectively communicated with the air flow access ends of the sandblaster 01 and the sprayer 02;

During operation, the rotary sandblasting method can be used to more effectively clean the welding slag inside the welding gun. During the sandblasting cleaning process, the compressed air in the air tank 16 will be used for back blowing to prevent metal sand from entering the air duct during the rotary sandblasting process and affecting subsequent welding. After the gun cleaning is completed, the sprayer 02 is used to spray the anti-spatter oil atomization. An atomization layer is formed on the surface of the contact tip and the shielding gas cover. After the spraying is completed, the shielding gas will be used for back blowing. Since an anti-spatter oil atomization layer is formed in the contact tip and the shielding gas cover, the adhesion of welding spatter can be greatly reduced during the subsequent welding process, and the sustainable welding can be extended.

[0024] Preferably, the sandblaster 01 includes a rotary sandblasting head, a collection cover 03 and a quick buckle 04. The rotary sandblasting head is arranged on the top of the sandblaster 01, and the collection cover 03 is fixed on the top of the sandblaster 01 and covers the rotary sandblasting head;

[0025] The rotary sandblasting head is located inside the collection cover 03. One end of the collection cover 03 is provided with a socket so that the robot can place the welding gun in the collection cover 03 and perform surface sandblasting cleaning through the rotary sandblasting head.

[0026] Preferably, the quick buckle 04 is arranged between the sandblaster 1 and the collection cover 03, and the sandblaster 01 and the collection cover 03 are fixedly connected through the quick buckle 04;

[0027] The sandblaster 01 body and the collecting cover 03 are fixed together by a quick buckle 04 and can be quickly disassembled for cleaning or maintenance.

[0028] Preferably, the sprayer 02 includes an atomizing head and a liquid storage tank that are connected;

[0029] A socket is provided at one end of the sprayer 02 so that the robot can put the welding gun in. During operation, the atomizing head sprays the welding gun with liquid through compressed air.

[0030] Preferably, a weighing module 09 is fixed at the bottom of the frame, a detection end of the weighing module 09 is fixedly connected to the bottom of the sand supply hopper 08, and a sand replenishing port 14 is provided at one end of the sand replenishing port channel 07;

[0031] The weighing module 09 is used to weigh the sand supply hopper 08, and the data is processed by its controller and fed back to the text display screen 12, so that personnel can know the inventory of the sand supply hopper 08, and personnel can add sand to the sand supply hopper 08 through the sand replenishment port 14 and the sand replenishment port channel 07.

[0032] Preferably, a pressure regulating valve 13 and a pressure gauge 05 are provided on the top of the frame, and the monitoring end of the pressure gauge 05 and the pressure regulating valve 13 are both connected to the gas tank 16;

[0033] The pressure of the gas tank 16 is monitored in real time through the pressure gauge 05, so that personnel can adjust the gas pressure of the gas tank 16 through the pressure regulating valve 13.

[0034] Preferably, an electric control cabinet 11 is provided on the top of the frame, and a text display screen 12 is provided on one side of the electric control cabinet 11;

[0035] The electric control cabinet 11 is used to provide power input and control requirements for the electrical components of the device, while the text display screen 12 is used to display operating data to assist personnel in operation.

[0036] Preferably, an air box 18 is fixed to the bottom of the frame;

[0037] Used to connect the electrical circuits of this device, such as power supply or signal circuits.

[0038] A specific application of this embodiment is as follows: The robot places the welding torch into the corresponding socket of the sandblaster 01 or the sprayer 02, and by giving a signal, the corresponding actions of gun cleaning and anti-spatter oil atomization spraying optimization can be completed. Each functional module has a different purpose. The vibrating screen 06 collects the used metal sand during the rotary sandblasting process of the sandblaster 01, screens it through the vibrating screen 06, and replenishes the useful metal sand into the sand supply hopper 08 again. In this way, the metal sand can be reused for gun cleaning, greatly reducing the usage amount of the metal sand. The sand replenishment port channel 07 can directly add metal sand from its sand replenishment port 14 when replenishing sand, and the metal sand can be added into the sand supply hopper 08 through this channel to complete the sand replenishment work. The function of the air tank 16 is that a large amount of compressed air is consumed during the sandblasting process. If only the compressed air pipe with a diameter of φ10 is used for air supply, there will be a large pressure drop during the entire sandblasting process, and the sandblasting air flow is unstable, resulting in poor consistency of the sandblasting gun cleaning effect. In order to reduce the instability of the compressed air pressure, the air tank 16 is used to reduce the pressure fluctuation of the compressed air and ensure the consistency of the gun cleaning effect. The function of the waste sand recovery bin 15 is that the residual large particle welding slag or the small particle waste sand lost during the sandblasting process, after being screened by the vibrating screen 06, the waste substances enter the waste sand recovery bin 15, which is convenient for manual cleaning of the waste sand during use.
