Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to a welding gun with a clamping assembly. Background Art

[0002] A welding gun with a clamping assembly is a specially designed welding tool. It adds a clamping assembly to the traditional welding gun, which assists the welding process to a certain extent, such as helping welders better control the welding angle and force, and improving the accuracy and efficiency of welding.

[0003] During the welding process, the user needs to operate the welding gun with one hand and use the other hand to deliver the welding wire. When welding small components to a small circuit board, the welding gun and the welding wire are in contact with the components and the surface of the circuit board. The circuit board and the components are very easy to slide, resulting in unsuccessful welding, and the user does not have extra hands to control the contact position between the circuit unit and the circuit board, which makes the welding process very complicated. Although there are some fixing fixtures on the market that use universal tubes and clips, in the actual welding process, it is encountered that when welding cables to circuit boards, some cables are very thin and very soft, and have no supporting force. If clamps are used to clamp, because the cables themselves have no supporting force, the head of the cable cannot be well controlled, resulting in multiple adjustments during welding, resulting in low welding efficiency.

[0004] In view of this, the present invention proposes a welding gun with a clamping assembly to solve the above technical problems. Summary of the invention

[0005] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments.

At the same time, the user can rotate the turntable so that the turntable drives the universal tube and the circuit board to rotate, thereby achieving a suitable welding angle and improving welding efficiency. When encountering welding cables, the user can guide the cables to be welded into the universal positioning tube, and then fix the head of the cable by using the fixing assembly, and then control the position of the cable head by adjusting the universal positioning tube to achieve a suitable welding position. There is no need to perform cumbersome operations of adjusting the cable position multiple times during welding because the cable is soft and has no support, which further improves the welding efficiency.

DETAILED DESCRIPTION

[0018] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example like Figure 1-Figure 7 As shown, a welding gun with a clamping assembly comprises a fixture table 1, on which a fixture assembly 4 is provided, and the fixture assembly 4 comprises a turntable 41, and the turntable 41 is rotatably connected to the fixture table 1, and four groups of universal tubes 42 are provided on the turntable 41, and a wire clamping assembly 5 is provided at the end of one group of universal tubes 42, and the wire clamping assembly 5 comprises a back plate 51, and the back plate 51 is fixedly connected to the end of the universal tube 42, and a slide groove 52 is provided on the back plate 51, and a slider 53 is slidably connected in the slide groove 52, and a universal positioning tube 55 is fixedly connected to the slider 53, and a fixing assembly 6 is provided on the universal positioning tube 55, and an extension assembly 7 for pulling a cable is also provided on the universal positioning tube 55; The ends of the universal tubes 42 of three of the four groups are fixedly connected with first fixing clips 43; The fixture table 1 is also fixedly connected to a welding gun rack 2, in which a welding gun 3 is placed; The slider 53 is provided with a first positioning knob 54 , and the first positioning knob 54 is used to fix the positions of the slider 53 and the universal positioning tube 55 .

[0020] In the embodiment, the user can clamp the circuit board or component to be welded by the first fixing clamp 43, and then adjust the universal tube 42 to achieve a convenient welding angle. At the same time, the user can rotate the turntable 41 so that the turntable 41 drives the universal tube 42 and the circuit board to rotate, thereby achieving a suitable welding angle. Traditional welding requires the user to control the welding gun 3 with one hand and the welding wire with the other hand, without extra hands to control the circuit board to be welded, especially the circuit board with a small volume. When the welding gun 3 and the welding wire come into contact with the surface, the circuit board is very easy to slide, resulting in unsuccessful welding. At the same time, when welding a smaller circuit unit to the circuit board, the user does not have extra hands to control the contact position of the circuit unit and the circuit board, resulting in a very complicated welding process.

[0021] It should be noted that one of the universal tubes 42 in the present invention is specially used for clamping cables for welding. During the welding process, the cables will be welded to the circuit board. However, some cables are very thin and soft and have no supporting force. If the first fixing clamp 43 is used for clamping, the cable head cannot be well controlled because the cable itself has no supporting force, resulting in multiple adjustments during welding, resulting in low welding quality. When the wire clamping assembly 5 in the present invention is used, the cable to be welded is first introduced into the universal positioning tube 55, and the head of the cable is kept extending out of the universal positioning tube 55 for subsequent welding. Then, the head of the cable is fixed by the fixing assembly 6, and then the position of the cable head is controlled by adjusting the universal positioning tube 55 to achieve a suitable welding position.

[0022] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the fixing assembly 6 includes an air collecting unit 61, an end of the universal positioning tube 55 away from the universal tube 42 is fixedly connected to an air bag 64, the air collecting unit 61 is fixedly connected to the air bag 64 through the air guide tube 62, and a tightening reel 63 is fixedly connected to the back plate 51, and the tightening reel 63 is used to tighten the air guide tube 62; The gas collecting unit 61 includes an air storage pipe 611, which is fixedly connected to the back plate 51, and a piston 614 is slidably connected in the air storage pipe 611. The end of the piston 614 close to the slider 53 is fixedly connected to a push rod 612, and the push rod 612 extends out of the air storage pipe 611. The push rod 612 is on the movement path of the slider 53. The end of the air storage pipe 611 away from the slider 53 is fixedly connected to the air guide pipe 62, and the end of the piston 614 away from the slider 53 is fixedly connected to one end of a spring 613, and the other end of the spring 613 is fixedly connected to the bottom of the air storage pipe 611. An exhaust valve 66 and an air intake pipe 65 are fixedly connected to both sides of the air storage pipe 611 , and a one-way valve is disposed inside the exhaust valve 66 and the air intake pipe 65 .

[0023] In the embodiment, after the cable is introduced into the universal positioning tube 55, the user pushes the slider 53 to drive the universal positioning tube 55 and the cable to slide in the slide groove 52, and the universal positioning tube 55 drives the cable to extend out of the back plate 51 close to the circuit board. During the sliding process of the slider 53, the slider 53 pushes the push rod 612, and the push rod 612 drives the piston 614 to slide in the air storage tube 611 and compress the spring 613. When the piston 614 slides in the air storage tube 611, it pushes the air in the air storage tube 611 through the guide tube. The air tube 62 enters into the airbag 64, which is annular and fits on the inner wall of the end of the universal positioning tube 55. After gas enters the airbag 64, it expands and fixes the head of the cable (the airbag 64 is retractable and can fix cables of different thicknesses). The tightening reel 63 can tighten the air tube 62 (the tightening reel 63 is a prior art and will not be described in detail here) to prevent the air tube 62 from being entangled. After the universal positioning tube 55 is extended, the position of the universal positioning tube 55 is fixed by the first positioning knob 54.

[0024] It should be noted that an exhaust valve 66 is installed on the gas storage tube 611. Because the volume of gas filled into the airbag 64 is different when the airbag 64 fixes cables of different thicknesses, the exhaust valve 66 is used to discharge excess gas filled into the airbag 64 by the gas storage tube 611 while maintaining the air pressure in the airbag 64.

[0025] When welding is completed, when the user slides the slider 53 and the universal positioning tube 55 to reset, since the push rod 612 is no longer subjected to the thrust of the slider 53, the spring 613 in the gas storage tube 611 stretches and drives the piston 614 to slide and reset. At this time, the air guide tube 62 generates suction, and the air bag 64 contracts, and gas enters the air intake tube 65 (there is a one-way valve in the air intake tube 65 that can only allow air to enter but not exit, and there is also a one-way valve in the exhaust valve 66 that can only allow air to exit but not enter). After the air bag 64 contracts, it no longer fixes the cable. At the same time, the cable has been welded to the circuit board at this time. Therefore, when the slider 53 drives the universal positioning tube 55 to slide and reset, the welded cable is separated from the universal positioning tube 55.

[0026] like Figure 4-Figure 7 As shown, the extension assembly 7 includes a fixing frame 72, and the fixing frame 72 is fixedly connected to the end of the universal positioning tube 55 away from the slider 53, and a steel sheet 71 is slidably connected in the fixing frame 72, and a second fixing clamp 74 is fixedly connected to the end of the steel sheet 71 away from the slider 53, and a second positioning knob 73 for fixing the position of the steel sheet 71 is provided on the fixing frame 72; The steel sheet 71 is elastic and can be bent along with the universal positioning tube 55 .

[0027] In the embodiment, the already fixed cable is clamped by the second fixing clamp 74. During welding, if the cable is not successfully welded to the circuit board, a part of the cable will be consumed. At this time, the steel sheet 71 can be pushed, and the steel sheet 71 can pull a part of the cable out of the universal positioning tube 55 through the second fixing clamp 74 (although the airbag 64 fixes the cable, under the action of increased tension, the cable will slide relative to the airbag 64), and then the position of the steel sheet 71 and the cable is fixed by the second positioning knob 73, and a second welding is performed.

[0028] The steel sheet 71 is an elastic steel sheet 71 and can bend along with the universal positioning tube 55 .

[0029] The workflow is as follows: First, clamp the circuit board and other components that need to be welded onto the first fixing clamp 43, and adjust the universal tube 42 to achieve a convenient welding angle. At the same time, the user can rotate the turntable 41 so that the turntable 41 drives the universal tube 42 and the circuit board to rotate, thereby achieving a suitable welding angle. When welding soft cables, the first fixing clamp 43 can no longer meet the requirements of fixing the cables. At this time, the cable to be welded is introduced into the universal positioning tube 55, and the head of the cable is kept extending out of the universal positioning tube 55 for subsequent welding. Then, the slider 53 is pushed to drive the universal positioning tube 55 and the cable to slide in the slide groove 52. The universal positioning tube 55 drives the cable to extend out of the back plate 51 close to the circuit board. During the sliding process of the slider 53, the slider 53 pushes the push rod 612, and the push rod 612 drives the piston 614 in the gas storage tube 611 The piston 614 slides inside the gas storage tube 611 and compresses the spring 613. When the piston 614 slides inside the gas storage tube 611, it pushes the air inside the gas storage tube 611 into the air bag 64 through the air guide tube 62. The air bag 64 is annular and fits on the inner wall of the end of the universal positioning tube 55. After the gas enters the air bag 64, it expands and fixes the head of the cable. At the same time, after the universal positioning tube 55 is extended, the position of the universal positioning tube 55 is fixed by the first positioning knob 54. Then, the position of the cable head is controlled by adjusting the universal positioning tube 55 to achieve a suitable welding position. During welding, if the cable is not successfully welded to the circuit board, a part of the cable will be consumed. At this time, the steel sheet 71 can be pushed, and the steel sheet 71 can be pulled out of the universal positioning tube 55 through the second fixing clamp 74. Then, the position of the steel sheet 71 and the cable is fixed by the second positioning knob 73, and the second welding is performed. When welding is completed, when the user slides the slider 53 and the universal positioning tube 55 to reset, since the push rod 612 is no longer pushed by the slider 53, the spring 613 in the gas storage tube 611 stretches and drives the piston 614 to slide and reset. At this time, the air guide tube 62 generates suction, and the air bag 64 contracts, and the air enters the suction tube 65. After the air bag 64 contracts, it no longer fixes the cable. At the same time, the cable has been welded to the circuit board at this time. Therefore, when the slider 53 drives the universal positioning tube 55 to slide and reset, the welded cable is separated from the universal positioning tube 55.
