Description

Technical Field

[0001] This invention relates to the field of feeding machine technology, specifically to an automatic feeding and bonding machine for new energy SMT. Background Technology

[0002] SMT stands for Surface Mount Technology, which is one of the most popular technologies and processes in the electronics assembly industry. Surface mount technology for electronic circuits is also known as surface mount or surface mounting technology. It is a circuit assembly technology that mounts leadless or short-lead surface mount components (SMC / SMD, also known as chip components) onto the surface of a printed circuit board (PCB) or other substrates, and then assembles them by reflow soldering or dip soldering.

[0003] In existing circuit board assembly processes, circuit patches are typically mounted to pre-defined installation positions on the circuit board surface. During circuit board production, the circuit patches are placed at these mounting positions. These circuit patches are generally elongated strips. During the transfer process, a transfer device lifts and moves the entire circuit patch to the predetermined mounting position. However, since circuit patches are usually placed together and moved to the vicinity of the processing station before being transferred to the circuit board surface, it is difficult for them to remain parallel to the circuit board during this process. Furthermore, during the transfer and mounting process, misalignment may occur between the circuit patch and the predetermined mounting position on the circuit board surface, preventing it from being placed in the intended location and thus affecting subsequent production. Summary of the Invention

[0007] As a further embodiment of the present invention, the shifting gantry includes two sets of columns, both sets of columns are fixedly connected to the surface of the frame, and both sets of columns are fixedly connected to the upper ends of a telescopic gantry beam. The two gantry beams are arranged in parallel, and the surface of the gantry beams is provided with two first drive chains.

[0011] As a further embodiment of the present invention, driving cylinders are fixedly connected to both sides of the sliding block, and the ends of the two driving cylinders are connected to the side of the pressure block. The pressure block slides on the surface of the sliding block. A groove is formed inside the sliding block, and a through groove is formed on the surface of the sliding block corresponding to the end of the driving cylinder. The through groove communicates with the groove. A connecting rod is fixedly connected to the side of the driving cylinder near the through groove. A retractable swing rod is rotatably connected to the end of the connecting rod. The middle position of the swing rod is hinged to the inner wall of the groove.

[0013] As a further embodiment of the present invention, a fourth pressure roller is rotatably connected to the inner wall surface of the groove, the fourth pressure roller is in contact with the surface of the adjustment panel, and the fourth pressure roller is located on the side of the unfolding plate away from the light-transmitting glass plate.

[0014] As a further embodiment of the present invention, inclined plates are fixedly connected to the inner wall surface of the groove corresponding to the positions of the second and fourth pressure rollers.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. Before assembling the circuit board, the present invention places the circuit patch on the surface of a light-transmitting glass plate. Then, the drive chain moves the detection camera module, which takes pictures of the circuit patch from the bottom. When the circuit patch is detected to be tilted, multiple rotating seats work together to adjust the adjustment panel, which helps to adjust the position of the circuit patch so that it is parallel to the carrier board. This ensures that the circuit patch is subsequently bonded to the carrier board and avoids the circuit patch not being parallel to the carrier board, which would prevent the circuit patch from being bonded to its predetermined position on the carrier board and affect the subsequent production and processing of the carrier board and the circuit patch.

[0017] 2. In the process of inspecting the circuit patch, the inspection camera module takes pictures of the circuit patch. When the inspection camera module detects that the branch of the circuit patch is shorter than the normal branch, the pressure block moves to the position of the branch. The first guide plate, which is closer to the pressure roller, moves to the position of the branch first. Then, during the movement, the first guide plate gradually moves from the middle to both sides of the circuit patch. The curled branch of the circuit patch gradually unfolds under the action of the first guide plate. The first pressure roller rolls the unfolded circuit patch, which helps to guide the curled branch of the circuit patch to unfold and roll and shape it, avoiding the circuit patch branch from curling and not being able to fit well with the carrier board, thus affecting the subsequent processing and use of the circuit patch and the carrier board.

[0018] 3. In the process of the camera module taking pictures of the circuit patch, when the camera module detects that the branch of the circuit patch is significantly curled (i.e., the branch length of the circuit patch is short), the drive cylinder will cause the pressure block to move upward a certain distance, causing the end of the unfolding plate to rotate downward to the adjustment panel position. When the unfolding plate moves to the position of the circuit patch, the end of the unfolding plate will move against the surface of the light-transmitting glass plate. The end of the unfolding plate will move below the circuit patch. After the circuit patch moves above the unfolding plate, it will move along the surface of the unfolding plate. The end of the circuit patch will move between the second pressure roller and the unfolding plate. The upwardly curved circuit patch will be between the two pressure rollers. Under the action of the cone on the side, the circuit patch branches that bend downwards will be located on both sides of the unfolding plate. As the unfolding plate moves, the curled circuit patch branches will gradually unfold along the edge of the unfolding plate. After the end of the circuit patch passes through the second pressure roller and the unfolding plate, it will move to the position of the third pressure roller. The small motor will drive the reversing column and the third pressure roller to rotate. The third pressure roller will roll the circuit patch and convey it to one side. This is beneficial for rolling the downward curled circuit patch branches when the curling degree is large, ensuring the subsequent bonding of the circuit patch and the carrier board. It also avoids the circuit patch bending downwards too much, as direct downward pressure will cause the circuit patch to bend and affect its use. Attached Figure Description

Detailed Implementation

[0038] Please see Figures 1-17This invention provides a technical solution: an automatic SMT feeding and bonding machine for new energy, including a frame 1, an outer cover 2 fixedly connected to the upper end of the frame 1, a carrier track 1001 on the surface of the frame 1 for transferring products, a shifting gantry 1002 on the surface of the frame 1 for moving the carrier board 3 and the circuit patch 4 to the work station for assembly, a conveying mechanism 1003 on one side of the frame 1 for conveying the carrier board 3 and the circuit patch 4, and an angle adjustment mechanism 1004 on the surface of the frame 1 for detecting and adjusting the position of the circuit patch 4 before assembling it with the carrier board 3.

[0039] The vehicle track 1001 includes two sets of support plates 5. Both sets of support plates 5 are fixedly connected to the surface of the frame 1. Track side plates 6 are fixedly connected to the surface of both sets of support plates 5. Drive belts 7 are drivenly connected to the side surfaces of the two track side plates 6 that are close to each other. Carrier plates 3 are placed on the two drive belts 7. Multiple stops 8 are fixedly connected to the surface of the two track side plates 6.

[0040] The shifting gantry 1002 includes two sets of columns 9, both sets of columns 9 are fixedly connected to the surface of the frame 1, and both sets of columns 9 are fixedly connected to the upper end of a telescopic gantry beam 10. The two gantry beams 10 are arranged in parallel, and the surface of the gantry beams 10 is provided with two first drive drag chains 11. The two first drive drag chains 11 are used to control the extension and retraction of the two ends of the gantry beams 10 on both sides. The upper surfaces of the two gantry beams 10 are fixedly connected to two parallel gantry longitudinal beams 12. The surface of the two gantry longitudinal beams 12 is provided with a drive assembly 13. The bottom of the drive assembly 13 is provided with multiple suction cups 14. The drive assembly 13 is used to drive the suction cups 14 to move up and down.

[0041] The transport mechanism 1003 includes two carrier trolleys 15, which are located below two gantry longitudinal beams 12 respectively. Multiple carrier plates 3 and multiple circuit patches 4 are placed on the two carrier trolleys 15 respectively.

[0042] The angle adjustment mechanism 1004 includes multiple bases 16, which are fixedly connected to the surface of the frame 1. Rotary seats 17 are fixedly connected to the surface of each of the multiple bases 16. An adjustment panel 18 is fixedly connected to the surface of each of the multiple rotating seats 17. A light-transmitting glass plate 19 is provided in the middle of the adjustment panel 18. The surface of the light-transmitting glass plate 19 is used to place the circuit patch 4. Multiple detection camera modules 20 are slidably connected to the surface of the frame 1. The multiple detection camera modules 20 are located below the light-transmitting glass plate 19. The detection camera modules 20 are used to detect the circuit patch 4 on the surface of the light-transmitting glass plate 19. A second drive drag chain 21 is fixedly connected between the surface of the detection camera module 20 and the frame 1. The adjustment panel 18 is located on one side of the track side plate 6.

[0043] Before assembling the circuit board, the carrier board 3 and the circuit patch 4 need to be placed on the surface of two carrier trolleys 15. Then, the carrier trolleys 15 with the carrier board 3 and circuit patch 4 are moved to the bottom of the gantry longitudinal beams 12 on both sides of the frame 1. Then, the new energy SMT automatic feeding and bonding machine is started. The first drive will cause the gantry crossbeam 10 to extend and retract. The gantry longitudinal beam 12 and the suction cup 14 will move to the top of the carrier board 3 and the circuit patch 4 under the action of the gantry crossbeam 10. Then, the drive ring assembly is activated. The suction cups 14 are controlled to move downwards, and the suction cups 14 on both sides will pick up the carrier plates 3 and circuit patches 4 from the two carrier trolleys 15 respectively. Then, the carrier plates 3 will be moved to the surface of the two drive belts 7 under the action of the first drive chain 11 and the drive assembly 13. The carrier plates 3 will be placed on the surface of the two drive belts 7. Multiple stops 8 are used to limit the carrier plates 3. The circuit patches 4 will be moved to the surface of the light-transmitting glass plate 19 under the action of the first drive chain 11 and the drive assembly 13. The circuit patch 4 is placed on the surface of the light-transmitting glass plate 19. Then, the second drive drag chain 21 drives the detection camera module 20 to move. The detection camera module 20 takes pictures of the circuit patch 4 from the bottom. When the circuit patch 4 is detected to be tilted, the adjustment panel 18 is adjusted by the cooperation of multiple rotating seats 17. This helps to adjust the position of the circuit patch 4 so that the circuit patch 4 can be kept parallel to the carrier plate 3. This ensures that the circuit patch 4 is subsequently bonded to the carrier plate 3. It avoids the circuit patch 4 not being parallel to the carrier plate 3, which would cause the circuit patch 4 to not be bonded to the predetermined position on the carrier plate 3, affecting the subsequent production and processing of the carrier plate 3 and the circuit patch 4. After the circuit patch 4 is adjusted, the suction cup 14 will pick up the adjusted circuit suction cup 14 again and move it to the predetermined position on the surface of the carrier plate 3. After the multiple circuit patches 4 on the surface of the carrier plate 3 are bonded, the drive belt 7 will transport the carrier plate 3 out of the outer cover 2 and then proceed to the next round of production.

[0044] During the testing of the circuit patch 4, the circuit patch 4 has multiple branches on both sides, which can easily cause the branches of the circuit patch 4 to curl during storage and transportation. As a further solution of the present invention, two sliding grooves 22 are opened on the surface of the adjustment panel 18. The two sliding grooves 22 are arranged in parallel and located on both sides of the light-transmitting glass plate 19. A sliding block 23 is slidably connected in the two sliding grooves 22. A small motor 24 is fixedly connected to the surface of the sliding block 23 near the two sliding grooves 22. A rotating wheel 25 is fixedly connected to the surface of the output shaft of the small motor 24. The rotating wheel 25 is in contact with the surface of the adjustment panel 18. A triangular pressure block 26 is provided on the side of the sliding block 23 near the light-transmitting glass plate 19. The side of the pressure block 26 near the light-transmitting glass plate 19 is pointed. A pressure wheel 27 is rotatably connected to the side of the pressure block 26 near the light-transmitting glass plate 19. A first guide plate 28 is fixedly connected to both sides of the pressure block 26. The first guide plate 28 is arranged at an angle and the end of the first guide plate 28 is arc-shaped. A first pressure roller 29 is rotatably connected to the bottom of the pressure block 26.

[0045] During the inspection of the circuit patch 4, the inspection camera module 20 takes pictures of the circuit patch 4. When the inspection camera module 20 detects that the branch of the circuit patch 4 is shorter than that of a normal circuit patch 4, the small motor 24 starts and drives the rotating wheel 25 to rotate. The sliding block 23 moves closer to the light-transmitting glass plate 19 in the sliding groove under the action of the rotating wheel 25. The pressure block 26 and the pressure roller 27 move together. Then the pressure roller 27 moves to the position of the circuit patch 4 and rolls from the middle position of the end of the circuit patch 4 to the surface of the circuit patch 4. During the movement of the pressure block 26... During the process, when the pressure block 26 moves to the branch position of the circuit patch 4, the first guide plate 28 near the pressure roller 27 will first move to the branch position of the circuit patch 4. Then, during the movement, the first guide plate 28 will gradually move from the middle to both sides of the circuit patch 4. The curled branch of the circuit patch 4 will gradually unfold under the action of the first guide plate 28. The first pressure roller 29 will roll the unfolded circuit patch 4, which is beneficial to guide the curled branch of the circuit patch 4 to unfold and roll and shape it, so as to avoid the circuit patch 4 branch from curling and not being able to fit well with the carrier plate 3, thereby affecting the subsequent processing and use of the circuit patch 4 and the carrier plate 3.

[0046] During the testing of the circuit patch 4, if the branches of the circuit patch 4 are significantly curled, the curling direction of the branches of the circuit patch 4 may be downward. As a further solution of the present invention, driving cylinders 30 are fixedly connected to both sides of the sliding block 23. The ends of the two driving cylinders 30 are connected to the side of the pressure block 26. The pressure block 26 slides on the surface of the sliding block 23. A groove 31 is provided inside the sliding block 23. A through groove 32 is provided on the surface of the sliding block 23 corresponding to the end of the driving cylinder 30. The through groove 32 communicates with the groove 31. A connecting rod 33 is fixedly connected to the side of the driving cylinder 30 near the through groove 32. A retractable swing rod 34 is rotatably connected to the end of the connecting rod 33. The middle position of the swing rod 34 is hinged to the inner wall of the groove 31. The front and rear inner walls of the groove 31 are... An unfolding plate 35 is elastically hinged to the surface. The unfolding plate 35 is tapered on the side near the light-transmitting glass plate 19 and sloped at the end near the light-transmitting glass plate 19. The end of the swing rod 34 extends to the bottom of the unfolding plate 35. A second pressure roller 36 is rotatably connected to the surface of the unfolding plate 35. The second pressure roller 36 is tapered at both ends and located in the middle of the unfolding plate 35. A gap is left between the second pressure roller 36 and the unfolding plate 35. A third pressure roller 37 is rotatably connected to the inner wall surface of the groove 31. A reversing column 38 is rotatably connected to the inner wall surface of the groove 31. The reversing column 38 is in contact with the surface of the third pressure roller 37. The small motor 24 is a double-headed motor. The output shaft of the small motor 24 extends through the sliding block 23 to the position of the reversing column 38. The output shaft of the small motor 24 is in contact with the reversing column 38.

[0047] During the process of the camera module 20 taking pictures of the circuit patch 4, when the camera module 20 detects that the branch of the circuit patch 4 is too curled (i.e., the branch length of the circuit patch 4 is too short), the drive cylinder 30 will move the pressure block 26 upward a certain distance to prevent the pressure roller 27 from directly pressing down on the circuit patch 4, which would cause the downward-curving branch of the circuit patch 4 to be more curved. The pressure roller 27 and the first guide plate 28 will still unfold the upward-curved branch of the circuit patch 4. The upward movement of the end of the drive cylinder 30 will drive the connecting rod 33 to move upward together. The connecting rod 33 will move the end of the swing plate upward together. The swing plate will rotate around the hinge point. The end of the swing plate near the unfolding plate 35 will rotate downward. The end of the unfolding plate 35 near the light-transmitting glass plate 19 will rotate downward. The end of the unfolding plate 35 will contact the adjustment panel 18. Then the sliding block 23 and the pressure block 26 will move. When the unfolding plate 35 moves to the position of the circuit patch 4, the end of the unfolding plate 35 will move against the surface of the light-transmitting glass plate 19. After the circuit patch 4 moves below the unfolding plate 35 and above it, it moves along the surface of the unfolding plate 35. The end of the circuit patch 4 moves between the second pressure roller 36 and the unfolding plate 35. The upwardly curved circuit patch 4 unfolds under the conical action of the second pressure roller 36, and the downwardly curved branches of the circuit patch 4 are located on both sides of the unfolding plate 35. As the unfolding plate 35 moves, the curled branches of the circuit patch 4 gradually unfold along the edge of the unfolding plate 35, and the end of the circuit patch 4 passes through... The second pressure roller 36 and the unfolding plate 35 will move to the position of the third pressure roller 37. The small motor 24 will drive the reversing column 38 and the third pressure roller 37 to rotate. The third pressure roller 37 will roll the circuit patch 4 and convey it to one side. This is beneficial when the branches of the circuit patch 4 are curled to a large degree. Rolling the downward curled branches of the circuit patch 4 will ensure the subsequent bonding of the circuit patch 4 with the carrier plate 3. It will also prevent the circuit patch 4 from bending downwards too much. Direct pressing will cause the circuit patch 4 to bend and affect its use.

[0048] During the testing of the circuit patch 4, when the branches of the circuit patch 4 curl to a certain extent and cannot be restored to use, the circuit patch 4 needs to be removed. As a further solution of the present invention, the surface of the pressure block 26 near the groove 31 is provided with a sliding groove 39, and a push plate 40 is elastically slidably connected in the sliding groove 39. The surface of the push plate 40 is provided with a slot 41, and a locking block 42 is elastically slidably connected in the sliding groove 39. The locking block 42 is located in the slot 41, and the end of the locking block 42 near the groove 31 is a slope.

[0049] During the testing of the circuit patch 4, when the branches of the circuit patch 4 curl to a certain extent and become unusable, the drive cylinder 30 will retract, causing the pressure block 26 to move upward. The pressure block 26 will then move the push plate 40 and the locking block 42 together. The locking block 42 will move to the edge of the groove 31, and then the groove 31 will press the locking block 42. The locking block 42 will release the limit on the push plate 40, and the push plate 40 will slide downward in the sliding groove 39. The bottom of the push plate 40 will fit against the adjustment panel 18. Subsequently, during the movement of the sliding block 23 and the pressure block 26, the push plate 40 will... The circuit patch 4 on the surface of the light-transmitting glass plate 19 is pushed out above the light-transmitting glass plate 19, which is beneficial for removing the circuit patch 4 with a large degree of curling. This avoids the circuit patch 4 with a large degree of curling being unable to be restored during the production process, thus wasting adjustment time and affecting production. After the circuit patch 4 is removed, the sliding block 23 returns to its original position, the drive cylinder 30 extends and returns to its original position, the pressure block 26 moves downward, the locking block 42 moves out again, and the push plate 40 will gradually move into the sliding groove 39. Then, when the locking groove 41 moves to the position of the locking block 42, the locking block 42 will limit the push plate 40 again.

[0050] During the process of adjusting the downward curling of the circuit patch 4, the circuit patch 4 will be lifted, and the position of the circuit patch 4 is prone to shift. As a further embodiment of the present invention, a fourth pressure roller 43 is rotatably connected to the inner wall surface of the groove 31. The fourth pressure roller 43 is in contact with the surface of the adjustment panel 18. The fourth pressure roller 43 is located on the side of the unfolding plate 35 away from the light-transmitting glass plate 19.

[0051] During the downward curling adjustment of the circuit patch 4, the circuit patch 4 will move under the action of the third pressure roller 37. Then the circuit patch 4 will move to the position of the fourth pressure roller 43. The fourth pressure roller 43 will press the circuit patch 4 back onto the surface of the light-transmitting glass plate 19. This is beneficial to ensure that the adjusted circuit patch 4 can be pressed back onto the surface of the light-transmitting glass plate 19, and to avoid large displacement of the position of the circuit patch 4 during the adjustment rolling process, which would affect the subsequent bonding of the circuit patch 4 with the carrier board 3.

[0052] During the testing of the circuit patch 4, the end of the circuit patch 4 cannot be accurately moved below the second pressure roller 36 and the fourth pressure roller 43. As a further solution of the present invention, the inner wall surface of the groove 31 is fixedly connected with an inclined plate 44 corresponding to the positions of the second pressure roller 36 and the fourth pressure roller 43.

[0053] During the testing of the circuit patch 4, the sliding block 23 and the pressure block 26 move. The end of the circuit patch 4 will first move to the position of the second pressure roller 36. Under the action of the inclined plate 44, the end of the circuit patch 4 will move to the bottom of the second pressure roller 36. Subsequently, under the action of the inclined plate 44, the circuit patch 4 will move to the bottom of the fourth pressure roller 43. This facilitates the movement of the circuit patch 4 to the bottom of the second pressure roller 36 and the fourth pressure roller 43, ensuring the testing and adjustment of the circuit patch 4.
