Description

Technical Field

[0001] The utility model relates to the technical field of tin bar polishing, in particular to a tin bar cross-section polishing device. Background Art

[0002] Tin bar is a product of solder. Tin bar can be divided into leaded tin bar and lead-free tin bar, both of which are used for soldering circuit boards. Made of pure tin, it has good wettability and fluidity, and is easy to tin. The solder joints are bright and full, and there will be no undesirable phenomena such as cold soldering. Sufficient antioxidant elements are added to make it have strong antioxidant ability.

[0003] After the tin bar is formed, its cross section is not smooth enough and needs to be polished. The traditional polishing method is that the staff polishes the tin bars one by one with a handheld polishing machine, which increases the workload of the staff and is inefficient, which is not conducive to improving production capacity. In view of this, we propose a tin bar cross section polishing device. Utility Model Content

DETAILED DESCRIPTION

[0024] 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.

[0025] See also Figure 1-Figure 4 The utility model provides a tin bar cross-section polishing device, comprising a base 1 and two support plates 2 fixedly connected to the base 1, and a guide rail 3 fixedly connected between the two support plates 2. Specifically, the two support plates 2 are symmetrically arranged, and the two ends of the guide rail 3 are respectively fixedly installed on the two support plates 2 by bolts. A slide seat 4 is slidably connected to the guide rail 3, and a mounting frame 5 is fixedly connected to both sides of the slide seat 4. The mounting frame 5 is provided with a plurality of placement seats 6 for placing tin bars, and the plurality of placement seats 6 are distributed in a straight line at equal distances along the length direction of the mounting frame 5, and each placement seat 6 can place a tin bar.

[0026] Combination Figure 2 and Figure 3 As shown, the placement seat 6 includes a side plate 61, one side of the side plate 61 is fixedly connected to the side of the mounting frame 5 away from the slide seat 4, so that the mounting frame 5 can drive the placement seat 6 to move, and then drive the tin bar to move. The top of the other side of the side plate 61 is fixedly connected to a three-sided frame 63 for limiting the tin bar, and the bottom of the other side of the side plate 61 is fixedly connected to a four-sided frame 62 for placing the tin bar.

[0027] Furthermore, a movable plate 64 is slidably connected to the inner wall of the four-sided frame 62 , and the bottom of the movable plate 64 is elastically connected to the bottom wall inside the four-sided frame 62 via a spring 65 .

[0028] After being formed, some tin bars have a certain curvature in cross section. By providing a movable plate 64 and a spring 65, the tin bar can be moved up and down, so that the polishing mechanism 7 can adapt to the curvature of the top surface of the tin bar and polish along the curved surface.

[0029] As an embodiment, a polishing mechanism 7 is disposed on the base 1 for polishing the top surface of the tin bar placed in the placement seat 6 .

[0030] Specifically, the polishing mechanism 7 in this embodiment includes a support frame 71, which is fixedly connected to the base 1. A motor 72 is fixedly installed on the support frame 71. The output end of the motor 72 is connected to a drive shaft 73. The drive shaft 73 is rotatably installed on the support frame 71 through a bearing. Two polishing wheels 74 are fixedly installed on the drive shaft 73. The two polishing wheels 74 are respectively used to polish two groups of tin bars.

[0031] As an embodiment, the tin bar cross-section polishing device further includes a moving mechanism 8 for driving the tin bar placement seat 6 to slide along the guide rail 3, so that the tin bar passes through the polishing mechanism 7 in sequence, thereby being automatically polished.

[0032] Combination Figure 4 As shown, the moving mechanism 8 includes a hanger 81, the top of which is fixedly connected to the inner top wall of the support frame 71, and the inner wall of the hanger 81 is rotatably connected to a transmission shaft 82 through a bearing, and two gears 83 are fixedly connected to the transmission shaft 82, and the two gears 83 are meshed with racks 84, and the two racks 84 are respectively fixedly connected to the tops of the two mounting frames 5. When the transmission shaft 82 rotates, the two gears 83 can be driven to rotate synchronously, and the two gears 83 drive the two mounting frames 5 to move through the racks 84, and then drive the two groups of tin bar placement seats 6 to move, so that the two rows of tin bars move along the length direction of the guide rail 3 at the same time, and when the tin bars pass under the polishing wheel 74, they can be automatically polished.

[0033] Please continue reading Figure 4 A large pulley 86 is fixedly connected to the transmission shaft 82, and a small pulley 85 is fixedly connected to the drive shaft 73. The small pulley 85 is connected to the large pulley 86 through a belt. The diameter of the large pulley 86 is larger than the diameter of the small pulley 85. The small pulley 85 drives the large pulley 86 to rotate, which can achieve the purpose of deceleration, thereby preventing the tin bar from moving too fast and affecting the polishing effect.

[0034] When the tin bar cross-section polishing device of the utility model is used, the tin bars are first vertically inserted into the placement seats 6 one by one, the bottom of the tin bars contacts the movable plate 64, and the top surface of the tin bars is exposed outside the placement seats 6. Each placement seat 6 can be inserted with a tin bar, and after all the tin bars are placed in the placement seats 6, the motor 72 is started to start polishing.

[0035] During polishing, the output end of the motor 72 drives the driving shaft 73 to rotate, and the driving shaft 73 drives the two polishing wheels 74 to rotate at the same time. At the same time, the driving shaft 73 drives the large pulley 86 to rotate through the small pulley 85, thereby driving the transmission shaft 82 to rotate, and the transmission shaft 82 simultaneously drives the two gears 83 to rotate, and the two gears 83 drive the rack 84 to move along the length direction of the guide rail 3 through meshing. The rack 84 synchronously drives the mounting frame 5 to move, thereby making the two rows of placement seats 6 move forward along the direction of the guide rail 3, and when the tin bars in the placement seats 6 pass under the polishing wheel 74, they can be automatically polished.
