Description

Technical Field

[0001] The utility model belongs to the technical field of tin soldering frames, and in particular relates to a tin soldering frame for producing PCB circuit boards. Background Art

[0002] The current soldering racks on the market need to put the roller on the roller shaft before processing the PCB circuit board, and then fit the roller shaft on the soldering rack. There are many steps, and most of them can only install one roller at a time, and need to be replaced many times. In actual use, since the two sides of the roller are not fixed, the roller is very easy to slide left and right when extracting, which causes the problem of extraction jamming. Therefore, a soldering rack for PCB circuit board production is designed to solve the problem that the current soldering rack has cumbersome loading steps and is prone to jamming during use. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] (1) The utility model is provided with a flexible blocking strip, a flexible blocking strip and a positioning rod, etc. During installation, it is only necessary to press down the roller so that after squeezing the flexible blocking strip, it is successively sleeved on the positioning rod and squeezes the lifting plate downward, forcing the spring to deform.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-Figure 2As shown, the utility model provides the following technical solutions: a soldering rack for PCB circuit board production includes side panels 12, a base 5, a roller 2 and a lifting structure, the lifting structure includes a positioning rod 7, L-shaped side panels 12 are symmetrically installed on both sides of the surface of the base 5, and a positioning rod 7 is installed in the middle of the surface of the base 5, the roller 2 is embedded between the side panels 12 and is sleeved on the positioning rod 7, the lifting structure is used to control the distance between the roller 2 and the base 5, the lifting structure also includes a lifting plate 3 and a spring 4, a through hole is opened in the middle of the surface of the lifting plate 3, and the lifting plate 3 is sleeved on the positioning rod 7, the spring 4 is symmetrically installed at the bottom of both sides of the lifting plate 3, and the lower end surface of the spring 4 is fixedly connected to the side panel 12, the bottom of the roller 2 is in contact with the surface of the lifting plate 3, and connecting plates 1 are symmetrically installed at both ends of the side wall of the side panel 12 and above the roller 2, the distance between the connecting plates 1 is greater than the diameter of the roller 2, and flexible blocking strips 13 are connected between the connecting plates 1, and the flexible blocking strips 13 are in contact with the surface of the roller 2.

[0019] Through the above technical scheme: during installation, the user only needs to press down the roller 2 so that it can be sleeved on the positioning rod 7 in sequence after squeezing the flexible blocking strip 13. At this time, the roller 2 squeezes the lifting plate 3 downward, forcing the spring 4 to deform. After the other rollers 2 are installed, the spring 4 and the flexible blocking strip 13 are used to lightly clamp the roller 2 from both sides. While ensuring that the roller 2 can rotate normally, the spring 4, the lifting plate 3 and the flexible blocking strip 13 are used to limit the up and down activity range of the roller 2, and the positioning rod 7 limits the left and right activity range of the roller 2, which solves the problem that the current soldering rack has complicated loading steps and is prone to jamming during use. At the same time, when disassembling the roller 2, it is only necessary to lift the roller 2 so that it can be taken out after squeezing the flexible blocking strip 13. At this time, under the action of the spring 4, the lifting plate 3 pushes the roller 2 below to move up again to complete the replacement, which not only facilitates disassembly but also increases the endurance of the soldering rack.

[0020] See also Figure 1-Figure 3 As shown, a first magnetic strip 6 is symmetrically installed on the surface of the base 5 and on both sides of the positioning rod 7, a second magnetic strip 8 is symmetrically installed on the bottom of the lifting plate 3 and on both sides of the through hole, the second magnetic strip 8 is arranged opposite to the first magnetic strip 6, a T-shaped rotating rod 11 is installed in the middle of the side wall of the side plate 12, an auxiliary plate 10 is sleeved on the rotating rod 11, a plurality of guide holes 9 of different sizes are evenly spaced on the surface of the auxiliary plate 10, a rotating hole is opened at one end of the surface of the auxiliary plate 10, a rubber ring 14 is glued and fixed in the rotating hole, the rotating rod 11 passes through the rubber ring 14 and extends to the outside of the auxiliary plate 10, and the inner wall of the rubber ring 14 is in contact with the surface of the rotating rod 11.

[0021] Through the above technical solution: since the device can be installed with multiple rollers 2, different models of rollers 2 can be installed on the device when meeting different needs, and the position of the guide hole 9 can be changed by rotating the auxiliary plate 10 on the rotating rod 11 to make it correspond to different rollers 2, and then the materials of different diameters are passed through the guide hole 9 on the auxiliary plate 10 to achieve the purpose of rapid adjustment without disassembly and replacement. At the same time, the installed rubber ring 14 is used to increase the static friction between the auxiliary plate 10 and the rotating rod 11, thereby ensuring the stability of the auxiliary plate 10 after rotation. In addition, the installed first magnetic strip 6 and the second magnetic strip 8 can be used to assist the spring 4 and the lifting plate 3 in applying an upward thrust to the roller 2, thereby ensuring the limiting effect.
