Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a soldering flux coating device. Background Art

[0002] Flux is an auxiliary material used in welding. The main function of flux is to remove oxides on the surface of solder and base material to be welded, so that the metal surface reaches the necessary cleanliness. It prevents the surface from being oxidized again during welding, reduces the surface tension of solder, and improves welding performance. However, the traditional coating method is to stop welding and put down the welding gun when flux is needed during welding, and then use the flux coating device to coat the welding points with flux, and then put down the coating device, pick up the welding gun and continue welding, repeating this process over and over again. It is very inconvenient and troublesome to operate. In view of the existing problems, a flux coating device is proposed. Utility Model Content

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A flux coating device is designed, including a welding gun, the welding gun is sleeved with a cylinder on the outside, a threaded sleeve is rotatably installed on the top of the cylinder, teeth are arranged on the end of the threaded sleeve, and the teeth are meshed with a gear ring, a knob is fixedly installed on the outside of the gear ring, a fixing groove is opened on the outside of the cylinder, a fixing strip is fixedly installed on the bottom of the knob, the fixing strip matches the fixing groove, a screw rod is threadedly connected to the threaded sleeve, a piston is fixedly connected to the bottom end of the screw rod, the piston is sleeved on the welding gun and abuts against the cylinder, an injection port is arranged on the outside of the cylinder, the injection port is provided with threads, and the injection port is threadedly connected to a screw cap.

[0008] Preferably, a limit block is fixedly installed on the top of the screw rod, a limit plate is fixedly installed inside the cylinder, the limit plate is penetrated by the screw rod, and the limit plate is sleeved on the welding gun.

[0009] Preferably, anti-slip bumps are provided on the outer side of the cylinder.

[0010] Preferably, a cylinder cover is extrusion-mounted on the bottom of the cylinder.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example

[0018] Reference Figure 1-4A solder flux coating device includes a welding gun 8, the welding gun 8 is sleeved with a barrel 1 on the outside, a threaded sleeve 13 is rotatably mounted on the top of the barrel 1, the end of the threaded sleeve 13 is provided with teeth, and the teeth are meshed with a toothed ring 14, the number of teeth and the diameter of the toothed ring 14 are six times the number of teeth and the diameter of the threaded sleeve 13, so one turn of the toothed ring 14 is equal to six turns of the threaded sleeve 13, and the operation is labor-saving, a knob 4 is fixedly mounted on the outside of the toothed ring 14, a fixing groove 16 is opened on the outside of the barrel 1, and a fixing strip 15 is fixedly mounted on the bottom of the knob 4, and the fixing The strip 15 matches the fixing groove 16. Through the matching between the fixing strip 15 and the fixing groove 16, the knob 4 is fixedly set at a fixed position of the cylinder 1, so that the knob 4 will not be separated from the cylinder 1, and the meshing between the gear ring 14 and the threaded sleeve 13 is guaranteed. The threaded sleeve 13 is threadedly connected with a screw rod 6, and the bottom end of the screw rod 6 is fixedly connected with a piston 10. The piston 10 is sleeved on the welding gun 8 and abuts against the cylinder 1. An injection port 11 is arranged on the outer side of the cylinder 1. The injection port 11 is provided with threads, and the injection port 11 is threadedly connected with a screw cap 5.

[0019] A hole is formed on the outside of the cylinder 1, and an observation plate 3 is fixedly connected in the hole.

[0020] The observation board 3 is a transparent PC board structure. The PC board structure is adopted mainly for its strong light transmission and filtering, and it is not easy to turn yellow or atomize after long-term use. It has strong impact resistance and is not deformed by changes in temperature and humidity. It is suitable for welding work. At the same time, it is also convenient for the staff to observe the remaining internal flux through the observation board 3, so as to know the internal situation and add flux.

[0021] A limiting block 7 is fixedly installed on the top of the screw rod 6, and a limiting plate 12 is fixedly installed inside the cylinder 1. The limiting plate 12 is penetrated by the screw rod 6, and the limiting plate 12 is sleeved on the welding gun 8. The limiting block 7 and the limiting plate 12 limit the lifting and lowering of the screw rod 6 to ensure that the screw rod 6 can only be lifted and lowered within a limited space, thereby ensuring that the piston 10 will not be separated from the welding gun 8, resulting in unnecessary resistance caused by the piston 10 sleeved on the welding gun 8 when descending, and also preventing the screw rod 6 from being separated from the threaded sleeve 13 due to the continuous decrease in the elasticity of the piston 10, thereby avoiding possible misalignment.

[0022] Anti-slip bumps are provided on the outside of the cylinder 1 to increase the friction between the staff's hands and the cylinder 1, to prevent the cylinder 1 from slipping from the staff's hands due to sweating of the hands due to long-term holding, causing damage to the equipment or safety problems for the staff.

[0023] A cylinder cover 2 is extrusion-mounted at the bottom of the cylinder body 1. When the device is not in use, the welding head and the needle 9 are covered by the cylinder cover 2 to avoid damage during storage or transportation.

[0024] In actual use, the staff first pulls the cylinder cover 2 off the cylinder body 1, and then turns the knob 4 counterclockwise. The knob 4 drives the gear ring 14 to rotate. When the gear ring 14 rotates, it drives the threaded sleeve 13 to rotate at the top of the cylinder body 1. The threaded sleeve 13 continues to drive the internally threaded screw 6 to rotate. When the screw 6 rotates, it will lift upward, thereby driving the piston 10 to lift upward until it is limited by the limit plate 12. The knob 4 can no longer rotate. At this time, the piston 10 has reached the highest point. After that, the screw cap 5 can be rotated to separate the screw cap 5 from the injection port 11, and then the entire device can be placed horizontally with the injection port 11 directly above. Then, the solder flux can be added to the inside of the cylinder body 1 from the injection port 11. After adding, first tighten the screw cap 5 on the injection port 11 by rotating it again to keep it sealed. Finally, turn the device upside down so that the needle 9 is directly above, and then turn the knob 4 clockwise to push the piston 10 downward, squeezing the air inside the piston 10 and the cylinder 1 out from the needle 9 until the flux is found to flow out from the needle 9. At this time, stop turning the knob 4. Through the internal seal between the piston 10 and the cylinder 1, the internal pressure and the external environment reach a certain balance, so that the flux will not flow out without the push of the piston 10 or other external pressure. At this time, the welding gun 8 can be used for welding. When the flux is needed, it is only necessary to turn the knob 4 clockwise to make the flux pushed by the piston 10 and flow from the needle 9 to the welding point below the welding gun 8. The staff does not need to switch the welding gun and the flux coating device back and forth, which reduces the operating steps and improves the practicability of the flux coating device.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
