Description

Technical Field

[0001] The utility model belongs to the technical field of anti-deformation of reflow soldering guide rails, in particular to an anti-deformation structure of reflow soldering guide rails. Background Art

[0002] Reflow rails play an important role in SMT production. They not only ensure the smooth progress of component soldering, but also have an important impact on improving production efficiency and ensuring soldering quality. Reasonable selection and maintenance of reflow rails can effectively improve the stability and economy of the production line.

[0003] Since reflow soldering will generate high temperature when soldering to circuit boards, and continuous soldering will keep the high temperature going, the existing reflow soldering rails do not have an anti-deformation structure, which makes the rails easily soften when exposed to high temperatures. Then the use of the equipment will cause the rails to deform, which not only affects the normal use of the reflow soldering equipment, but also causes damage when the rails are severely deformed, resulting in economic losses. Therefore, we propose a reflow soldering rail anti-deformation structure. Utility Model Content

Through the installation of several anti-deformation components, the stability of the two guide rails can be improved, the deformation can be reduced, the guide rails can be prevented from being damaged, and the normal operation of the equipment can be guaranteed, which solves the problem that the existing guide rails are prone to softening when subjected to high temperature, and then the use of the equipment will cause the guide rails to deform, which not only affects the normal use of the reflow soldering equipment, but also causes damage when the guide rails are severely deformed.

[0025] 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.

[0026] Please refer to Figures 1-6 As shown, the present utility model is an anti-deformation structure for the guide rail of a reflow soldering machine, including two guide rails 1. On one side of the two corresponding guide rails 1, a number of anti-deformation components 11 are provided. The number of anti-deformation components 11 is arranged in a horizontal array. The anti-deformation component 11 includes two positioning rods 111. On the back of the positioning rod 111 located in the front, an internal thread rotating ring 112 is rotatably connected. On the inner wall of the internal thread rotating ring 112, a limit ring 113 is fixedly connected. On the front of the positioning rod 111 located in the rear, a fixed thread block 114 is fixedly connected. A threaded hole is opened on the back of the internal thread rotating ring 112. The outer surface of the fixed thread block 114 is threadedly connected to the inner wall of the threaded hole. On one side of the two positioning rods 111 away from each other, a T-shaped insert block 115 is fixedly connected. On one side of the two corresponding guide rails 1, a fixed rod 13 is fixedly connected. A number of T-shaped grooves are opened in the two fixed rods 13. The T-shaped grooves are inserted with the T-shaped insert blocks 115. By setting the anti-deformation component 11, specifically, the two positioning rods 111 are respectively inserted into the fixed rods 13 on the two guide rails 1 through the T-shaped insert blocks 115. Then, the internal thread rotating ring 112 is rotated clockwise so that the internal thread rotating ring 112 moves on the fixed thread block 114. The two positioning rods 111 move away from each other and are closely attached to the two guide rails 1 through the T-shaped insert blocks 115. By installing a number of anti-deformation components 11, the stability of the two guide rails 1 can be improved, the situation of deformation can be reduced, the guide rails 1 can be prevented from being damaged, and the normal operation of the equipment can be ensured.

[0027] Both of the two guide rails 1 are provided with cavities inside. A cooling component 12 is arranged inside the cavity. The cooling component 12 includes three shunt tubes 122 fixed to the inner wall of the guide rail 1. Shunt boxes 121 are fixedly connected to both the left and right sides of the guide rail 1. Water inlet connectors 123 are fixedly connected to the sides of the two shunt boxes 121 away from the guide rail 1. A conical adjustment block 124 is arranged inside the shunt box 121 on the right side. A fixed block 241 is fixedly connected to the top of the conical adjustment block 124. A connecting block 242 is fixedly connected to the left side of the fixed block 241. A screw rod 125 is threadedly connected to the top of the shunt box 121 on the right side. A turning handle 251 is fixedly connected to the top of the screw rod 125. A ring-shaped push block 252 is fixedly connected to the bottom of the screw rod 125. The surface of the ring-shaped push block 252 is in contact with the surface of the connecting block 242. By setting the shunt tube 122, specifically, when the turning handle 251 is rotated clockwise to drive the screw rod 125 to rotate, the ring-shaped push block 252 moves downward, thereby pushing the connecting block 242 to the left. The connecting block 242 drives the conical adjustment block 124 to move together through the fixed block 241, opening the left side of the water inlet connector 123, then the coolant enters the shunt box 121. Subsequently, the coolant is shunted through the three shunt tubes 122, thereby cooling the high-temperature guide rail 1, preventing the guide rail 1 from deforming again, protecting the guide rail 1 from damage, and improving the service life.

[0028] Two sliding holes are opened inside the fixed block 241. Stabilizing rods 243 are slidably connected to the inner walls of the two sliding holes. Springs 244 are sleeved on the outer surfaces of the two stabilizing rods 243. The springs 244 are located on the right side of the fixed block 241. The left sides of the springs 244 are fixedly connected to the right side of the fixed block 241. The right sides of the springs 244 are fixedly connected to the inner wall of the shunt box 121. The left and right sides of the stabilizing rods 243 are fixedly connected to the inner wall of the shunt box 121. When the turning handle 251 is rotated counterclockwise, the screw rod 125 drives the ring-shaped push block 252 to move upward, then the fixed block 241 drives the conical adjustment block 124 to reset to the right under the elastic action of the spring 244.

[0029] An annular limiting groove is opened on the back surface of the positioning rod 111 in the front. The outer surface of the limiting ring 113 is rotatably connected to the inner wall of the annular limiting groove. The inner surface of the inner-threaded rotating ring 112 is in contact with the outer surface of the positioning rod 111. The side of the limiting ring 113 close to the positioning rod 111 is in contact with the back surface of the positioning rod 111. The inner-threaded rotating ring 112 rotates on the positioning rod 111 in the front through the limiting ring 113, so that the two positioning rods 111 move away from each other smoothly.

[0030] The shunt tube 122 communicates with the shunt box 121. Both the left and right sides of the conical adjusting block 124 are provided with conical surfaces. The conical adjusting block 124 is adapted to the inside of the water inlet joint 123. The water inlet joint 123 on the right is for water inlet, and the water inlet joint 123 on the left is for water outlet. Moving the conical adjusting block 124 by different distances can control the opening size of the water inlet joint 123, thereby regulating the flow rate of the coolant and enabling regulation according to different needs.

[0031] One side of the connecting block 242 close to the annular pushing block 252 is provided with an inclined surface. The inclined surface on the connecting block 242 is higher on the left and lower on the right. The side surface of the annular pushing block 252 close to the connecting block 242 is provided with a chamfer. The chamfered part on the side surface of the annular pushing block 252 is adapted to the inclined surface on the connecting block 242. Since the chamfered part on the side surface of the connecting block 242 is adapted to the inclined surface on the connecting block 242, when the annular pushing block 252 moves downward, it can smoothly push the connecting block 242.

[0032] A specific application of this embodiment is:

[0033] The lengths of the two positioning rods 111 are adjusted by rotating the internal threaded swivel 112, so that the two positioning rods 111 are smoothly inserted into the fixed rods 13 on the two guide rails 1 through the T-shaped plug blocks 115, and then the internal threaded swivel 112 is rotated clockwise to move the internal threaded swivel 112 on the fixed threaded block 114, and the internal threaded swivel 112 is rotated on the front positioning rod 111 through the limit ring 113, so that the two positioning rods 111 are moved away from each other, so that they are tightly attached to the two guide rails 1 through the T-shaped plug blocks 115, and the two guide rails 1 are positioned and stabilized. By installing a plurality of anti-deformation components 11, the stability of the two guide rails 1 can be improved, the deformation can be reduced, the guide rails 1 can be prevented from being damaged, and the normal operation of the equipment can be ensured. At the same time, the water inlet joint 123 on the shunt box 121 on the right side of the guide rail 1 is connected to the pipeline for conveying the coolant into the shunt box 121, and the water inlet joint 123 on the shunt box 121 on the left side of the guide rail 1 is connected to the pipeline. It is used to discharge the coolant. After the pipeline is connected, the screw 125 is driven to rotate by turning the handle 251 clockwise, and the annular push block 252 moves downward, thereby pushing the connecting block 242 to the left, and the connecting block 242 drives the conical adjusting block 124 to move together through the fixed block 241. The fixed block 241 stretches the spring 244. After the conical adjusting block 124 moves to the left, the left side of the water inlet joint 123 will be opened, and the coolant will enter the diversion box 121. Then the coolant will be diverted through the three diversion pipes 122, so as to cool the high-temperature guide rail 1, and prevent the guide rail 1 from deformation again, protect the guide rail 1 from damage, and increase the service life. The coolant in the diversion pipe 122 will flow to the diversion box 121 on the left, and then be discharged through the pipeline on the left water inlet joint 123. The conical adjusting block 124 moves different distances to control the opening size of the water inlet joint 123, thereby adjusting the flow rate of the coolant, which can be adjusted according to different needs.
