Description

Technical Field

[0001] This invention relates to the field of electronic circuit board technology, specifically to a device for double-sided welding of microelectronic circuit boards. Background Technology

[0002] Electronic circuit boards are the core components in electronic devices that carry and connect various electronic components. They realize electrical connections between components through conductive lines and have the functions of signal transmission, circuit control and energy distribution. Electronic circuit boards fix the signal transmission path between components through printed circuits to realize conduction and electrical connection.

[0003] In the production of electronic circuit boards, components need to be soldered onto the surface of the circuit board. Currently, when soldering electronic circuit boards, they need to be placed on a soldering table, and the operator needs to press and fix the electronic circuit board by hand, and also operate the soldering gun to solder the electronic circuit board. This soldering method will affect the stability of the electronic circuit board soldering. Uneven force applied by the operator will cause the electronic circuit board to tilt, which can easily lead to misalignment of the soldering position on the electronic circuit board. Summary of the Invention

[0004] The purpose of this invention is to provide an apparatus for double-sided welding of microelectronic circuit boards to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

A connecting plate is fixedly connected to the telescopic end of the electric actuator. A slant frame is fixedly connected to the end of the connecting plate away from the electric actuator.

[0011] Furthermore, there are two through-hole brackets and two support brackets, both of which are symmetrically arranged around the base plate. The top of the through-hole bracket extends above the top of the groove bracket. The top of the base plate is horizontally aligned with the bottom of the inner wall of the groove bracket. There are two inclined brackets, which are symmetrically arranged around the electric actuator rod. The bottoms of the two inclined brackets are far apart from each other.

[0012] Furthermore, the welding component includes a limiting plate, the bottom of which is fixedly connected to the top of the workbench. A bracket is fixedly connected to the surface of the limiting plate, and a right-angle plate is fixedly connected to the end of the bracket. A limiting slide rod is fixedly connected to the end of the limiting plate away from the bracket. A sliding hole plate is slidably connected to the surface of the limiting slide rod. An inclined plate is sleeved on the surface of the sliding hole plate. A pressure plate is hinged to the top of the inclined plate. An extrusion rod is fixedly connected to the top of the pressure plate. The end of the extrusion rod away from the pressure plate is fixedly connected to the telescopic surface of the electric push rod. A circular frame is fixedly connected to the end of the sliding hole plate away from the limiting plate. A welding robot is mounted on the end of the circular frame away from the sliding hole plate.

[0013] Furthermore, there are two limiting plates, which are symmetrically arranged around the worktable. The surface of the pressure plate is in contact with the inner wall of the right-angle plate, and the end of the circular frame near the sliding plate is in contact with the end of the limiting slide rod.

[0014] Furthermore, the pushing component includes a storage rack, the bottom of which is fixedly connected to the bottom of the inner wall of the groove, a protective pad is fixedly connected to the inner wall of the storage rack, a slide plate is fixedly connected to the end of the worktable, a movable frame is slidably connected to the surface of the slide plate, a connecting rod is fixedly connected to the surface of the movable frame, a pushing plate is fixedly connected to the end of the connecting rod away from the movable frame, a synchronizing rod is fixedly connected to the surface of the connecting rod, and the end of the synchronizing rod away from the connecting rod is fixedly connected to the surface of the circular frame.

[0015] Furthermore, the bottom of the pusher plate contacts the top of the protective pad, the end of the linkage rod away from the moving frame extends into the interior of the storage rack, and the end of the storage rack extends to the outer end of the worktable.

[0016] Furthermore, the unloading component includes an electric rod, the end of which is fixedly connected to the inner wall of the limiting groove. A fixed frame is fixedly connected to the telescopic end of the electric rod, and a friction pad is fixedly connected to the top of the fixed frame. A limiting hole is opened on the top of the base plate, and multiple rollers are rotatably connected to the inner wall of the limiting hole. The top of the friction pad contacts the bottom of the rollers, and the rollers are located at the ends of the two through-hole frames that are close to each other.

[0017] The present invention has the following beneficial effects:

[0018] The grooved belt of this invention drives the transmission belt to rotate when it rotates. When the transmission belt rotates, it pushes the electronic circuit board to slide inside the grooved frame. The transmission belt will transport the electronic circuit board to the inside of the stabilizing component for compression and fixation. After the electronic circuit board is placed inside the grooved frame, the transmission belt will transport it, which improves the convenience of soldering and loading the electronic circuit board.

[0019] When the inclined frame moves downward, it uses the inclined surface to press the electronic circuit board, allowing the electronic circuit board to fully enter the two through-hole frames at their closest points. When the upper end of the electronic circuit board contacts the upper surface of the inclined frame, the inclined frame will limit the electronic circuit board. The two inclined frames limit the electronic circuit board to prevent misalignment. After the electronic circuit board contacts the upper surface of the inclined frame, the pressing plate will also contact the top of the electronic circuit board as the electric push rod extends. The pressing plate presses the top of the electronic circuit board, improving the stability of the electronic circuit board during soldering and preventing the electronic circuit board from shaking during soldering, which would affect the soldering effect.

[0020] The present invention uses a sliding plate to push a welding robot toward the surface of an electronic circuit board via a circular frame, thereby adjusting the position of the welding robot. When the welding robot moves away from the end of the through-hole frame, the distance between the welding robot and the electronic circuit board is greater, making it easier for the operator to observe the condition of the electronic circuit board after welding, avoiding burns caused by contact between the operator and the welding robot, and improving the safety of the electronic circuit board during welding.

[0021] When the pusher plate of this invention moves, it pushes the electronic circuit board inside the protective pad. The movement of the pusher plate pushes the electronic circuit board to the end of the protective pad, making it convenient for operators to collect the soldered electronic circuit board. The storage rack limits the electronic circuit board and prevents it from falling. The storage rack is equipped with a protective pad to protect the electronic circuit board and prevent damage if it tipps over. When the linkage rod moves, it pushes the moving frame to slide on the surface of the slide plate, improving the stability of the pusher plate during movement.

[0022] After the electronic circuit board of this invention is soldered, the electric rod is activated to push the fixing frame to move. The fixing frame pushes the friction pad to move at the bottom of the roller. When the friction pad moves, it pushes the roller to rotate inside the limiting hole through friction. When the roller rotates, it pushes the electronic circuit board to move into the storage rack and separates it from the through hole frame, which facilitates the unloading of the soldered electronic circuit board and improves the convenience of soldering the electronic circuit board.

[0023] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-9 As shown, the present invention is a device for double-sided welding of microelectronic circuit boards, including a worktable 1, a groove 3 on the top of the worktable 1, a support leg 2 fixedly connected to the bottom of the worktable 1, and a transmission component 4 on the surface of the worktable 1.

[0038] The transmission component 4 includes a grooved frame 10, the bottom of which is fixedly connected to the top of the workbench 1. A drive rod 13 is rotatably connected to the top of the inner wall of the grooved frame 10. A grooved belt 12 meshes with the surface of the drive rod 13, and a transmission belt 11 is fixedly connected to the surface of the grooved belt 12. A limit groove 14 is formed at the bottom of the workbench 1. A mounting plate 15 is fixedly connected to the top of the inner wall of the limit groove 14. A power device 17 is fixedly connected to the bottom of the inner wall of the mounting plate 15. The output end of the power device 17 is fixedly connected to the bottom of the drive rod 13. A gear 16 is fixedly connected to the lower surface of the drive rod 13. After the electronic circuit board is placed inside the grooved frame 10, the power device 17 is started to drive the transmission rod 11. When the moving rod 13 rotates, the driving rod 13 drives the gear 16 to rotate. At this time, the two gears 16 will rotate inside the limiting groove 14 through meshing. The two driving rods 13 drive the groove belt 12 to rotate inside the groove frame 10 through the gears 16. When the groove belt 12 rotates, it drives the transmission belt 11 to rotate. When the transmission belt 11 rotates, it pushes the electronic circuit board to slide inside the groove frame 10. The transmission belt 11 will transport the electronic circuit board to the inside of the stabilizing component 5 for compression and fixation. The top of the worktable 1 is provided with the stabilizing component 5, the top of the worktable 1 is provided with the welding component 6, the surface of the worktable 1 is provided with the pushing component 7, and the inside of the limiting groove 14 is provided with the unloading component 8.

[0039] There are two conveyor belts 11, which are symmetrically arranged with the groove frame 10 as the center. The ends of the two conveyor belts 11 that are close to each other extend into the interior of the groove frame 10. The bottom of the drive rod 13 passes through the groove frame 10 and extends into the interior of the limiting groove 14. There are four drive rods 13.

[0040] The four drive rods 13 are set in two groups, and each group has two rods. The two groups of drive rods 13 are symmetrically arranged with the transmission belt 11 as the center. The gears 16 are located inside the limiting groove 14. There are two gears 16, and the two gears 16 mesh with each other.

[0041] The stabilizing component 5 includes a base plate 21, the bottom of which is fixedly connected to the top of the workbench 1. A through-hole frame 22 is fixedly connected to the top of the base plate 21. A support frame 20 is fixedly connected to the top of the workbench 1. A bending frame 27 is fixedly connected to the top of the support frame 20. An electric actuator 25 is fixedly connected to the top of the inner wall of the bending frame 27. A spring rod 24 is fixedly connected to the bottom of the electric actuator 25. A pressing plate 28 is fixedly connected to the bottom of the spring rod 24. A connecting plate 26 is fixedly connected to the telescopic end of the electric actuator 25. A slant frame is fixedly connected to the end of the connecting plate 26 away from the electric actuator 25. 23. After the conveyor belt 11 transports the electronic circuit board into the through-hole frame 22, the electric push rod 25 is activated to move downward. When the electric push rod 25 moves downward, it pushes the inclined frame 23 downward through the connecting plate 26. When the inclined frame 23 moves downward, it uses the inclined surface to squeeze the electronic circuit board, so that the electronic circuit board can completely enter the two through-hole frames 22 at the ends that are close to each other. When the upper end of the electronic circuit board contacts the upper surface of the inclined frame 23, the inclined frame 23 will limit the electronic circuit board. The two inclined frames 23 limit the electronic circuit board to prevent it from being misaligned.

[0042] There are two through-hole brackets 22 and two support brackets 20. Both the two through-hole brackets 22 and the two support brackets 20 are symmetrically arranged with the base plate 21 as the center. The top of the through-hole bracket 22 extends above the top of the groove bracket 10. The top of the base plate 21 is horizontal with the bottom of the inner wall of the groove bracket 10. There are two inclined brackets 23. The two inclined brackets 23 are symmetrically arranged with the electric push rod 25 as the center. The bottoms of the two inclined brackets 23 are far apart from each other.

[0043] Welding component 6 includes a limiting plate 30. The bottom of the limiting plate 30 is fixedly connected to the top of the workbench 1. A bracket 31 is fixedly connected to the surface of the limiting plate 30. A right-angle plate 32 is fixedly connected to the end of the bracket 31. A limiting slide rod 33 is fixedly connected to the end of the limiting plate 30 away from the bracket 31. A sliding hole plate 36 is slidably connected to the surface of the limiting slide rod 33. An inclined plate 35 is sleeved on the surface of the sliding hole plate 36. A pressure plate 37 is hinged to the top of the inclined plate 35. A pressing rod 38 is fixedly connected to the top of the pressure plate 37. The end of the pressing rod 38 away from the pressure plate 37 is fixedly connected to the telescopic surface of the electric push rod 25. A circular frame 39 is fixedly connected to the end of the sliding hole plate 36 away from the limiting plate 30. A welding robot 34 is installed at the end of the frame 39 away from the sliding hole plate 36. When the electric push rod 25 moves downward, it pushes the pressure plate 37 downward through the extrusion rod 38. When the pressure plate 37 moves downward, it pushes the top of the inclined plate 35 downward. At this time, the lower end of the inclined plate 35 will push the sliding hole plate 36 to slide on the surface of the limiting slide rod 33. When the sliding hole plate 36 moves, it pushes the welding robot 34 to move towards the surface of the electronic circuit board through the circular frame 39, thereby adjusting the position of the welding robot 34. When the welding robot 34 moves to the end away from the through hole frame 22, the distance between the welding robot 34 and the electronic circuit board is greater, which makes it easier for the operator to observe the situation of the electronic circuit board after welding.

[0044] There are two limit plates 30, which are symmetrically arranged with the worktable 1 as the center. The surface of the pressure plate 37 is in contact with the inner wall of the right angle plate 32, and the end of the round frame 39 near the sliding hole plate 36 is in contact with the end of the limit slide rod 33.

[0045] The pushing component 7 includes a storage rack 40, the bottom of which is fixedly connected to the bottom of the inner wall of the groove 3. A protective pad 43 is fixedly connected to the inner wall of the storage rack 40. A sliding plate 45 is fixedly connected to the end of the worktable 1. A movable frame 46 is slidably connected to the surface of the sliding plate 45. A connecting rod 41 is fixedly connected to the surface of the movable frame 46. A pushing plate 42 is fixedly connected to the end of the connecting rod 41 away from the movable frame 46. A synchronizing rod 44 is fixedly connected to the surface of the connecting rod 41. The end of the synchronizing rod 44 away from the connecting rod 41 is fixedly connected to the surface of the circular frame 39. When the circular frame 39 moves, it pushes the connecting rod 41 to move via the synchronizing rod 44. When the connecting rod 41 moves, it pushes the pusher plate 42 to move on top of the protective pad 43. When the electronic circuit board moves into the inside of the protective pad 43, the pusher plate 42 pushes the electronic circuit board to move inside the protective pad 43. The movement of the pusher plate 42 pushes the electronic circuit board to the end of the protective pad 43, making it convenient for the operator to collect the soldered electronic circuit board. The storage rack 40 limits the electronic circuit board to prevent it from falling.

[0046] The bottom of the pusher plate 42 contacts the top of the protective pad 43, the end of the linkage rod 41 away from the moving frame 46 extends into the interior of the storage rack 40, and the end of the storage rack 40 extends to the outer end of the worktable 1.

[0047] The unloading component 8 includes an electric rod 50. The end of the electric rod 50 is fixedly connected to the inner wall of the limiting groove 14. A fixed frame 51 is fixedly connected to the telescopic end of the electric rod 50. A friction pad 52 is fixedly connected to the top of the fixed frame 51. A limiting hole 53 is opened on the top of the base plate 21. Multiple rollers 54 are rotatably connected to the inner wall of the limiting hole 53. The top of the friction pad 52 contacts the bottom of the roller 54. The roller 54 is located at one end of the two through-hole frames 22 that are close to each other. After the electronic circuit board is soldered, the electric rod 50 is started to push the fixed frame 51 to move. The fixed frame 51 pushes the friction pad 52 to move at the bottom of the roller 54. When the friction pad 52 moves, it pushes the roller 54 to rotate inside the limiting hole 53 through friction. When the roller 54 rotates, it pushes the electronic circuit board to move into the storage rack 40 and separates it from the through-hole frame 22.

[0048] In use, after placing the electronic circuit board inside the groove holder 10, the power unit 17 is activated to drive the drive rod 13 to rotate. The drive rod 13, in turn, drives the gear 16 to rotate. At this time, the two gears 16 mesh and rotate inside the limiting groove 14. The two drive rods 13, through the gears 16, drive the groove belt 12 to rotate inside the groove holder 10. The groove belt 12, in turn, drives the conveyor belt 11 to rotate. The conveyor belt 11, in turn, pushes the electronic circuit board to slide inside the groove holder 10. The conveyor belt 11 then transports the electronic circuit board to the stabilizing component 5 for compression and fixation. After the electronic circuit board is placed inside the groove holder 10, the conveyor belt 11 transports it, improving the convenience of soldering and loading the electronic circuit board. After conveying the electronic circuit board into the through-hole bracket 22, the electric push rod 25 is activated to move downwards. As the electric push rod 25 moves downwards, it pushes the inclined bracket 23 downwards via the connecting plate 26. The inclined bracket 23, moving downwards, uses its inclined surface to press against the electronic circuit board, allowing the electronic circuit board to fully enter the two through-hole brackets 22 at their closest points. When the upper end of the electronic circuit board contacts the upper surface of the inclined bracket 23, the inclined bracket 23 limits the electronic circuit board, preventing misalignment. After the electronic circuit board contacts the upper surface of the inclined bracket 23, the pressing plate 28 also contacts the top of the electronic circuit board as the electric push rod 25 extends, using the pressing plate 28 to press against the top of the electronic circuit board. The extrusion process improves the stability of the electronic circuit board during soldering, preventing it from shaking and affecting the soldering effect. When the electric push rod 25 moves downward, it pushes the pressure plate 37 downward through the extrusion rod 38. As the pressure plate 37 moves downward, it pushes the top of the inclined plate 35 downward. At this time, the lower end of the inclined plate 35 pushes the sliding hole plate 36 to slide on the surface of the limiting slide rod 33. When the sliding hole plate 36 moves, it pushes the welding robot 34 towards the surface of the electronic circuit board through the circular frame 39, thereby adjusting the position of the welding robot 34. When the welding robot 34 moves to the end away from the through hole frame 22, the distance between the welding robot 34 and the electronic circuit board is greater, making it easier for the operator to observe the post-soldering condition of the electronic circuit board and avoiding operator interference. To prevent burns from contact with the welding robot 34, and to improve safety during the welding of electronic circuit boards, the circular frame 39 moves by pushing the connecting rod 41 via the synchronous rod 44. The connecting rod 41, in turn, pushes the pusher plate 42 to move on top of the protective pad 43. Once the electronic circuit board is inside the protective pad 43, the pusher plate 42 continues to move it within the pad, pushing it to the end of the pad. This facilitates collection of the welded circuit board by the operator. A storage rack 40 is used to limit the movement of the circuit board, preventing it from falling. The storage rack 40 contains a protective pad 43 to protect the electronic circuit board.To prevent damage to the electronic circuit board after tipping over, the linkage rod 41 pushes the moving frame 46 to slide on the surface of the slide plate 45 during movement, improving the stability of the pusher plate 42 during movement. After the electronic circuit board is soldered, the electric rod 50 is activated to push the fixing frame 51 to move. The fixing frame 51 pushes the friction pad 52 to move at the bottom of the roller 54. As the friction pad 52 moves, it pushes the roller 54 to rotate inside the limiting hole 53. When the roller 54 rotates, it pushes the electronic circuit board to move into the storage rack 40 and separate it from the through-hole frame 22, facilitating the unloading of the soldered electronic circuit board and improving the convenience of soldering the electronic circuit board.
