Technical Field

[0001] The utility model belongs to the technical field of use of a special lead-free tin bar for welding machines, in particular to a special lead-free tin bar for welding machines which is easy to take. Background Art

[0002] Tin bar is a product of solder. Tin bar can be divided into lead tin bar and lead-free tin bar. Both are used for welding of circuit boards. They are made of pure tin, have good wettability and fluidity, and are easy to tin. Some tin bars have a longer structure. During the welding and transportation process, a protective shell is set on the outside. Before use, the shell needs to be removed.

[0003] At present, during the use of lead-free tin bars dedicated to welding machines, the protective shell encloses the protective structure and generally uses a plastic film structure. When disassembling, a tool structure is required, which can easily scratch the surface of the lead-free tin bar, causing damage to the lead-free tin bar and affecting subsequent use operations. When there are longer lead-free tin bars to be taken, after the protective shell is disassembled, it cannot be used up and continue to play a protective effect, causing damage to the lead-free tin bar.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figures 1 to 4 shown, the present utility model provides a lead-free solder bar for a welding machine that is convenient to retrieve, including a lead-free solder bar body 2. A retrieving tube 1 is sleeved outside the lead-free solder bar body 2. A pushing and retrieving component 4 is further included at the grooved position at the top of the retrieving tube 1;

[0026] The pushing and retrieving component 4 includes a guiding frame 41 that rotates inside the groove of the retrieving tube 1. A long slot is opened in the middle position of the guiding frame 41, and a pushing block 42 is slidably arranged inside the long slot of the guiding frame 41. The pushing block 42 can be guided and pushed inside the guiding frame 41 to control the lead-free solder bar body 2 located in the retrieving tube 1 to be pushed out. A traction plate 45 is fixedly arranged on one side of the pushing block 42 inside the retrieving tube 1, and the traction plate 45 is attached to one end of the lead-free solder bar body 2 inside the retrieving tube 1.

[0027] Adopting the above solution: The body of the lead-free solder bar 2 is protected by the picking tube 1. When it is necessary to pick up the lead-free solder bar 2 while protecting it, the guide frame 41 structure in the pushing and picking component 4 can be pressed down. By pulling the pushing block 42 structure inside the long slot of the guide frame 41, the traction plate 45 structure located inside the picking tube 1 can be driven to push the lead-free solder bar 2, and the lead-free solder bar 2 can be quickly taken out from the inside of the picking tube 1 to an appropriate length for use.

[0028] As Figure 1 、 Figure 2 、 Figure 3 shown, a pull plate 44 is fixedly arranged at the top of the pushing block 42. Both ends of the pushing block 42 are penetrated by fastening screws 43, and the fastening screws 43 are positioned inside the pushing block 42 in a spiral manner. Chute grooves 47 are symmetrically opened at the top of the guide frame 41, and the pull plate 44 is inserted into the inside of the chute grooves 47 through the bottom of the fastening screws 43. A roller 46 is rotatably arranged at the bottom end of the traction plate 45 through a groove structure and is attached to one side of the lead-free solder bar 2 located inside the picking tube 1.

[0029] Adopting the above solution: The fastening screw 43 structure is inserted into the inside of the pushing block 42, and the pushing block 42 is positioned to move inside the slotted opening of the guide frame 41 to maintain stable movement. The added traction plate 45 with the roller 46 structure can slide inside the picking tube 1, which can reduce the friction with the picking tube 1 and make the pushing more labor-saving.

[0030] As Figure 1 、 Figure 2 、 Figure 3 shown, a bracket 48 is fixedly arranged at the top of the picking tube 1, and the inside thereof includes a grooving component;

[0031] The grooving component includes a cutter 410 as a cutting structure. A lifting seat 49 is fixedly arranged at the top of the cutter 410 and moves along the groove direction inside the bracket 48. A pushing frame 411 is fixedly arranged at the top of the lifting seat 49. Limiting shafts 412 are symmetrically arranged on the front and rear sides of the lifting seat 49 and move up and down in the vertical grooves of the bracket 48.

[0032] Adopting the above solution: By pressing the pushing frame 411 structure inside the bracket 48 of the grooving component to descend, the cutter 410 can be controlled to press down into the groove of the picking tube 1 through the downward movement of the lifting seat 49 and the cutter 410 inside the bracket 48, so as to cut the lead-free solder bar 2 inside the picking tube 1 for segmented bending and picking.

[0033] As Figure 1 and Figure 4 shown, positioning feet 3 are symmetrically arranged on the outer side of the picking tube 1. The picking tube 1 further includes a pressing and folding component at one end of the grooving component;

[0034] The pressing and folding assembly includes a frame 5, and the frame 5 is rotatably arranged with the picking tube 1 through a connecting frame 9 rotatably arranged on the outside. A handle 8 is fixedly arranged on one surface of the frame 5. Springs 7 are symmetrically arranged on the outside of the frame 5, and the other ends of the springs 7 are fixedly arranged with connecting blocks 6 and are fixedly arranged with the picking tube 1 through the connecting blocks 6.

[0035] Adopting the above solution: Pull the handle 8 to control the frame 5 to rotate through the connecting frame 9, control the frame 5 to stretch the spring 7 to deform, and break the lead-free solder bar body 2 with a cut groove, making the picking operation more convenient.

[0036] The working principle and usage process of the present utility model:

[0037] The body of the lead-free solder bar body 2 is protected by the picking tube 1. While protecting the lead-free solder bar body 2, when picking is needed, the guide frame 41 structure in the pushing and picking assembly 4 can be pressed down. By pulling the pushing block 42 structure inside the long slot of the guide frame 41, the traction plate 45 structure located inside the picking tube 1 can be driven to start pushing the lead-free solder bar body 2, and the lead-free solder bar body 2 can be quickly taken out from the inside of the picking tube 1 to a suitable length for use. The fastening screw 43 structure is inserted into the inside of the pushing block 42, and the pushing block 42 is positioned to move inside the slot of the guide frame 41 to maintain stable movement. The added traction plate 45 cooperates with the roller 46 structure to slide inside the picking tube 1, which can reduce the friction with the picking tube 1 and make the pushing more labor-saving. By pressing the push frame 411 structure inside the cut groove component bracket 48 to descend, and through the lifting seat 49 and the cutting knife 410 moving downward inside the bracket 48, the cutting knife 410 can be controlled to press down into the slot of the picking tube 1 to cut the lead-free solder bar body 2 inside the picking tube 1 for segmented bending and picking. Pull the handle 8 to control the frame 5 to rotate through the connecting block 6, control the frame 5 to stretch the spring 7 to deform, and break the lead-free solder bar body 2 with a cut groove, making the picking operation more convenient. After picking is completed, the frame 5 is controlled to reset by the traction of the spring 7 inside the connecting frame 9.
