Description

Technical Field

[0001] This invention relates to the field of directional conveying technology, specifically to a directional conveying device for straightening a thin copper frame. Background Technology

[0002] As electronic devices become thinner and denser, thin copper frames have become a key carrier material for integrated circuit packaging. These strips commonly exhibit defects such as macroscopic warpage, edge waviness, and lateral bending after rolling and slitting, necessitating tension straightening in a straightening unit. However, traditional conveying mechanisms often employ simple clamping with upper and lower rubber rollers or belt dragging, which presents the following prominent problems:

[0003] Some models use gear pairs to transmit power. However, when dealing with workpieces of different sizes, the distance between the upper and lower rubber rollers needs to be adjusted. In most existing technologies, the lower rubber roller is fixed, while the upper rubber roller can be adjusted by vertical displacement. When adjusting the upper rubber roller, a frame, rectangular block, and bearing are set at one end. The rectangular block is slidably connected in the middle of the frame, and the rectangular block is raised and lowered by a lead screw. The rectangular block can synchronously drive the upper rubber roller to move, and one end of the upper rubber roller can rotate normally in the middle of the rectangular block through the bearing. Currently, after the distance between the upper and lower rubber rollers is adjusted, if it exceeds a certain distance (set at 5cm), it will cause the upper and lower gears to separate. At this time, the two gears will not be able to mesh and drive the upper and lower rubber rollers to rotate in opposite directions. When this problem occurs, it is necessary to stop the machine and replace it with a larger gear or rubber roller. However, if it is disassembled and replaced, the guide wheel needs to be removed, shims need to be added or removed, and then realigned, which is time-consuming and labor-intensive and cannot meet the needs of flexible production of multiple varieties and small batches.

[0004] Therefore, we have introduced a directional conveying device for straightening thin copper frames. Summary of the Invention

[0005] The purpose of this invention is to provide a directional conveying device for straightening thin copper frames, thereby solving the problems mentioned in the background above.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a directional conveying device for straightening a thin copper frame, comprising a first support, a second support, and a conveying assembly, wherein the first support and the second support are located on both sides of the conveying assembly;

[0007] The conveying assembly includes a lower rubber roller and an upper rubber roller. The upper rubber roller is located above the lower rubber roller. A fixed gear set is connected to one end of the lower rubber roller near the second bracket, and a movable gear set is connected to one end of the upper rubber roller near the second bracket. A lifting assembly is installed on the side of the second bracket away from the first bracket. A positioning assembly and a propulsion assembly are provided on the side of the movable gear set away from the second bracket. The positioning assembly is symmetrically arranged on both sides of the movable gear set and the propulsion assembly. An L-shaped rod is symmetrically arranged on the side of the lifting assembly away from the second bracket, and the L-shaped rod is located above the positioning assembly.

[0008] The lower rubber roller is symmetrically equipped with a first drive shaft at both ends, and the upper rubber roller is symmetrically equipped with a second drive shaft at both ends. A rectangular block is provided between the first bracket and the second bracket, and a rolling bearing is installed in the middle of the rectangular block. The first drive shaft, the second drive shaft and the rolling bearing are rotatably connected.

[0009] Limiting sliders are symmetrically installed on both sides of the rectangular block, and a lifting bar is fixedly installed on the upper end of the rectangular block. The surface of the lifting bar is marked with scale.

[0010] The fixed gear set includes a pinion A and a gear A, which are fixed to the outside of the first drive shaft.

[0011] The movable gear set includes a small gear B and a large gear B. The large gear B has a central hole in the middle, and limit protrusions are symmetrically installed on the inner wall of the central hole.

[0012] Furthermore, the lifting assembly includes a lifting plate, a top plate is fixedly installed on one of the upper sides of the lifting plate, and inclined grooves are symmetrically formed on the surface of the lifting plate.

[0013] Furthermore, the inclined chute is formed in a figure-eight shape.

[0014] Furthermore, the positioning component includes a base and a limiting plate slidably connected to the upper end of the base, and a rotating component is connected to the upper end of the limiting plate on the side away from the second bracket.

[0015] Furthermore, a support is fixedly installed on the upper end of the base on the side away from the second bracket, and a T-shaped slider is provided on the side of the base away from the support. A bearing seat is embedded in the middle of the support, and the rotating component is located above the bearing seat.

[0016] Furthermore, the limiting plate has an embedded hole in the middle of the side near the movable gear set, and a ball is rolled inside the embedded hole. A rack is installed on the lower side of the limiting plate, and a T-shaped sliding plate is installed on the side of the limiting plate away from the rack.

[0017] Furthermore, the rotating component includes a positioning gear and a cam mounted on the upper end of the positioning gear, with a connecting shaft connecting the positioning gear and the cam.

[0018] Furthermore, a connecting post is installed on one side of the upper end of the L-shaped rod, a baffle is installed on the other side of the connecting post, and anti-detachment sliders are symmetrically installed on both sides of the connecting post.

[0019] Furthermore, the propulsion assembly includes a fixed base and a through slot in the middle of the fixed base. A guide plate is provided on one side of the fixed base, and a movable hole is provided in the middle of the guide plate. A push plate is fixedly installed on one side of the guide plate, and a tail plate is fixedly provided at the bottom of the rear end of the guide plate.

[0020] Furthermore, a guide rod is fixedly installed in the middle of one side of the fixed base, and an annular plate is fixedly installed at the end of the guide rod away from the fixed base. A buffer spring is sleeved on the outside of the guide rod, and the buffer spring is located between the guide plate and the annular plate.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. This invention employs a two-stage meshing mechanism: small gear A engages with small gear B, and large gear A engages with large gear B. During the lifting process, the small gear first idles and guides, while the large gear gradually engages, achieving progressive meshing and impact-free synchronization. When the lifting plate moves upward with the upper rubber roller, the connecting column slides downward toward the inclined groove. At this time, the connecting column pulls the two symmetrically arranged positioning components away from each other via the L-shaped rod. When the upper rubber roller rises more than 5cm, the positioning components completely separate from the large gear B, facilitating the displacement of the large gear B and alignment with the large gear A. When the upper rubber roller falls less than 5cm, the large gear B can be moved away from the small gear B in advance. At this time, the connecting column slides upward toward the inclined groove, and then the connecting column pushes the two symmetrically arranged positioning components closer together via the L-shaped rod until one side of the limiting plate is inserted between the large gear B and the small gear B, thus eliminating the need to remove the upper and lower gears and the upper and lower rubber rollers, saving time and effort.

[0023] 2. This invention, through its linked propulsion components, can automatically push the large gear to move. When one side of the limiting plate is inserted between the large gear B and the small gear B, the rack can drive the positioning gear to rotate in reverse. When the L-shaped rod pulls the two symmetrically arranged positioning components away from each other, the rack can drive the positioning gear to rotate forward. A connecting shaft connects the positioning gear and the cam, allowing the positioning gear to drive the cam to rotate synchronously via the connecting shaft. When the cam is not rotating, it does not contact the guide plate. When the cam is driven to rotate, it will slide into contact with one side of the guide plate, at which point the guide plate will... The gear is pushed to move away from the fixed seat. After the limiting plate separates from the large gear B, the guide plate will move forward through the push plate, causing the push plate to push the large gear B to move closer to the small gear B. When the limiting plate moves to the side of the large gear B, the cam will rotate synchronously. At this time, the cam's protruding end will gradually separate from the guide plate, and the buffer spring will rebound the guide plate and push plate away from the large gear B. At this time, the large gear B is contacted and limited. Finally, the large gear B can be pulled away from the small gear B, so that the large gear B separates from the large gear A. There is no need to manually push the large gear to move, which is simple and convenient.

[0024] 3. The present invention has an embedding hole in the middle of the side of the limiting plate near the movable gear set. A ball is rolled inside the embedding hole. The ball rolls in contact with the surface of the large gear B and the small gear B, so as to avoid the limiting plate from causing wear on the surface of the large gear B and the small gear B.

[0037] 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.

[0038] Example 1:

[0039] Please see Figure 1-8A directional conveying device for straightening a thin copper frame includes a first support 1, a second support 2, and a conveying assembly 3. The first support 1 and the second support 2 are located on both sides of the conveying assembly 3. The outlet end of the device can be connected to a straightening machine or a leveling roller group. A slot is formed between the first support 1 and the second support 2. The conveying assembly 3 includes a lower rubber roller 31 and an upper rubber roller 32. The upper rubber roller 32 is located above the lower rubber roller 31 (steel core wrapped with EPDM rubber). First drive shafts 33 are symmetrically installed at both ends of the lower rubber roller 31, and second drive shafts 34 are symmetrically installed at both ends of the upper rubber roller 32. A rectangular block 35 is set between the first support 1 and the second support 2. A fixing nut is set at the upper end of the first support 1. An adjusting screw is threadedly connected to the middle of the fixing nut. A handle is installed at the upper end of the adjusting screw, and a movable bearing is set at the lower end of the adjusting screw. The upper end of the rectangular block 35 located on the side of the second drive shaft 34 away from the second bracket 2 is supported. When the adjusting screw is rotated forward, it can drive the upper rubber roller 32, the second drive shaft 34 and the corresponding rectangular blocks 35 on both sides to rise. When the adjusting screw is rotated in reverse, it can push the upper rubber roller 32, the second drive shaft 34 and the corresponding rectangular blocks 35 on both sides to fall. Limiting sliders 351 are symmetrically installed on both sides of the rectangular block 35 (both sides of the rectangular block 35 on the second drive shaft 34). Limiting grooves are symmetrically opened on the inner walls of both sides of the first bracket 1 and the second bracket 2. The rectangular block 35 on the second drive shaft 34 is slidably connected to the limiting groove through the limiting sliders 351, which facilitates the vertical lifting and lowering of the second drive shaft 34 and the upper rubber roller 32. When the adjusting screw is not rotated, the fixing nut can lock the adjusting screw to prevent it from rotating.

[0040] A rolling bearing 36 is installed in the middle of the rectangular block 35. The rolling bearing 36 is pressed into the center of the rectangular block 35, and a small amount of lithium-based grease is applied to the outer ring of the bearing. The first drive shaft 33 and the second drive shaft 34 are rotatably connected to the rolling bearing 36, so that while the first drive shaft 33 and the second drive shaft 34 rotate normally, the position of the second drive shaft 34 can be adjusted to achieve the clamping and conveying of the workpiece (copper frame). The roller spacing is adjustable to adapt to different thicknesses.

[0041] A fixed gear set 4 is connected to one end of the lower rubber roller 31 near the second bracket 2. A servo motor is installed at the end of the first drive shaft 33 away from the fixed gear set 4 to drive the first drive shaft 33 and the lower rubber roller 31 to rotate. When the first drive shaft 33 rotates, it can synchronously drive the fixed gear set 4 to rotate. The fixed gear set 4 includes a small gear A41 and a large gear A42. The diameter of the large gear A42 is larger than that of the small gear A41. Both the small gear A41 and the large gear A42 are fixed outside the first drive shaft 33. A movable gear set 5 is connected to one end of the upper rubber roller 32 near the second bracket 2. The movable gear set 5 includes a small gear B51 and a large gear B52. The small gear A41 and the small gear B51 have the same diameter and are aligned vertically to mesh with the turntable. A central hole 53 is opened in the middle of the large gear B52. Limiting protrusions 54 are symmetrically installed on the inner wall of the central hole 53. A straight groove is symmetrically opened on the surface of the second drive shaft 34. The limiting protrusions 54 slide with the straight groove, which facilitates the large gear B52 to follow. The second drive shaft 34 can rotate at different times while ensuring the linear displacement of the large gear B52. The second drive shaft 34 is detachable in the middle, and the connection method can be a conventional connection method such as thread, flange, or screw, which can be determined according to the needs. When the first drive shaft 33 rotates and drives the lower rubber roller 31 to rotate, the first drive shaft 33 can synchronously drive the small gear A41 to rotate. At this time, the small gear A41 will mesh with the small gear B51, so that the small gear B51 drives the upper rubber roller 3 through the second drive shaft 34. 2. Reverse rotation: When the workpiece passes through the space between the lower rubber roller 31 and the upper rubber roller 32, the opposing rotation of the lower rubber roller 31 and the upper rubber roller 32 can push the workpiece for centering and conveying. When the pinion A41 and the pinion B51 are aligned and meshed, the gear A42 and the gear B52 will be misaligned. The gear A42 will be close to the side of the pinion A41, and the gear B52 will be away from the pinion B51, leaving a gap between them. The gear A42 is located in the gap between the gear B52 and the pinion B51.

[0042] A lifting assembly 6 is installed on the side of the second support 2 away from the first support 1. A positioning assembly 7 and a propulsion assembly 9 are provided on the side of the movable gear set 5 away from the second support 2. The positioning assembly 7 can limit the movement between the large gear B52 and the small gear B51 (located on both sides of the large gear B52) to prevent the large gear B52 from moving towards the small gear B51 on its own. The positioning assembly 7 is symmetrically arranged on both sides of the movable gear set 5 and the propulsion assembly 9. An L-shaped rod 8 is symmetrically arranged on the side of the lifting assembly 6 away from the second support 2. The L-shaped rod 8 is located at the upper end of the positioning assembly 7.

[0043] When the diameter of the workpiece increases and the gap between the lower rubber roller 31 and the upper rubber roller 32 needs to be widened, as the upper rubber roller 32 moves upward (above 5cm), the aligned pinion A41 and pinion B51 will gradually separate. At this time, pinion A41 and pinion B51 will not be able to mesh. As the upper rubber roller 32 moves upward, the lifting component 6 will move upward synchronously, while the L-shaped rod 8 will move downward and drive the symmetrically arranged positioning components 7 to move away from each other. At this time, the positioning component 7 will move away from the large gear B52 and separate from it, and the pushing component 9 will push the large gear B52 to move synchronously, so that the large gear B52 moves towards the pinion B51 and fits together. At this time, the large gear A42 and the large gear B52 will be in an aligned meshing state (used for 5-10cm gap transmission between the upper rubber roller 32 and the lower rubber roller 31). When the first drive shaft 33 drives the large gear A42 to rotate, the large gear A42 will synchronously drive the large gear B52 to reverse, so that the large gear B52 drives the upper rubber roller 32 to rotate through the second drive shaft 34.

[0044] Once the gap is set, pinion A41 meshes with pinion B51, and gear A42 meshes with gear B52, forming a reverse synchronous transmission that drives the upper and lower rubber rollers to rotate at the same linear speed in opposite directions, achieving slip-free clamping and conveying.

[0045] Example 2:

[0046] Please see Figure 1-5 and Figure 9 The second bracket 2 has a through slot in the middle of its upper end. A lifting bar 352 is fixedly installed on the upper end of the rectangular block 35. The lifting bar 352 moves through the through slot. The surface of the lifting bar 352 has a scale 353 for observing the height of the lifting bar 352 when it is raised or lowered, so as to facilitate precise adjustment. The lifting assembly 6 includes a lifting plate 61. A top plate 62 is fixedly installed on one side of the upper end of the lifting plate 61. The top plate 62 and the lifting plate 61 are an integrated structure. When lifting, the L-shaped rod 8 moves up and down synchronously. The upper end of the lifting bar 352 is fixedly connected to the lower end of the top plate 62. When the rectangular block 35 drives the lifting bar 352 to adjust its height, the top plate 62 will drive the lifting plate 61 to adjust its height synchronously.

[0047] The surface of the lifting plate 61 is symmetrically provided with inclined sliding grooves 63. The inclined sliding grooves 63 are V-shaped with an included angle of 30 degrees. Their function is as follows: when the L-shaped rod 8 rises, the connecting column 81 slides outward along the sliding groove, pushing the positioning components 7 on both sides to move in opposite directions; when it descends, they move closer to each other to achieve one-way self-locking and prevent over-clamping. Inclined sliding grooves are provided on the inner walls of both sides of the inclined sliding groove 63. A connecting column 81 is installed on one side of the upper end of the L-shaped rod 8. The connecting column 81 passes through the inclined sliding groove 63. A baffle 82 is installed on the other side of the connecting column 81. The diameter of the baffle 82 is larger than that of the inclined sliding groove 63. Anti-detachment sliders 83 are symmetrically installed on both sides of the connecting column 81. The anti-detachment sliders 83 are slidably connected with the sliding grooves to prevent the connecting column 81 from separating from the inclined sliding groove 63.

[0048] When the lifting plate 61 moves upward with the upper rubber roller 32, the connecting column 81 will slide downward toward the inclined slide groove 63. At this time, the connecting column 81 will pull the two symmetrically arranged positioning components 7 away from each other through the L-shaped rod 8. When the upper rubber roller 32 rises more than 5cm, the positioning component 7 will completely separate from the large gear B52, so that the large gear B52 can be displaced and aligned with the large gear A42. When the upper rubber roller 32 falls less than 5cm, the large gear B52 can be moved away from the small gear B51 in advance. At this time, the connecting column 81 will slide upward toward the inclined slide groove 63. Finally, the connecting column 81 will push the two symmetrically arranged positioning components 7 closer to each other through the L-shaped rod 8 until one side of the positioning component 7 is inserted between the large gear B52 and the small gear B51, so as to avoid the large gear B52 and the large gear A42 from being aligned and engaged.

[0049] Example 3:

[0050] Please see Figure 1 , 2 4, 5, 9, 10. The positioning component 7 includes a base 71 (fixed to the ground or workbench by bolts) and a limiting plate 72 slidably connected to the upper end of the base 71. The limiting plate 72 can be inserted between the large gear B52 and the small gear B51 for blocking and limiting. A support 711 is fixedly installed on the upper end of the base 71 on the side away from the second bracket 2. A T-shaped slider is provided on the side of the base 71 away from the support 711. A rack 723 is installed on the lower end of the limiting plate 72. A T-shaped sliding plate 724 is installed on the side of the limiting plate 72 away from the rack 723. The T-shaped sliding plate 724 is slidably connected to the T-shaped slider to facilitate the parallel movement of the limiting plate 72.

[0051] A rotating component 73 is connected to the upper end of the limiting plate 72 on the side away from the second bracket 2. The rotating component 73 includes a positioning gear 731 and a cam 732 mounted on the upper end of the positioning gear 731. The cam 732 has an eccentric circular structure. The positioning gear 731 is meshed with the rack 723 to ensure that the two limiting plates 72 move synchronously and symmetrically to avoid skew. When the limiting plate 72 moves away from the large gear B52 and separates from it, the rack 723 can drive the positioning gear 731 to rotate forward. When the limiting plate 72 moves closer to the large gear B52 and contacts it, the rack 723 can drive the positioning gear 731 to rotate in reverse. A connecting shaft 733 is connected between the positioning gear 731 and the cam 732. The positioning gear 731 can drive the cam 732 to rotate synchronously through the connecting shaft 733. A bearing seat 712 is embedded in the middle of the support 711. The lower end of the connecting shaft 733 is rotatably connected to the bearing seat 712, which also facilitates the support 711 to support and limit the positioning gear 731 and the cam 732.

[0052] Example 4:

[0053] Please see Figure 5 and Figure 9 The limiting plate 72 has an insertion hole 721 in the middle of the side near the movable gear set 5. A ball 722 is rolled inside the insertion hole 721. The ball 722 rolls and contacts the surfaces of the large gear B52 and the small gear B51, so as to avoid the limiting plate 72 from causing wear on the surfaces of the large gear B52 and the small gear B51.

[0054] Example 5:

[0055] Please see Figure 1 , 2 4, 5, and 11, the propulsion assembly 9 includes a fixed base 91 (fixed to the ground or workbench by bolts) and a through slot 92 in the middle of the fixed base 91. A guide rod 911 is fixedly installed in the middle of one side of the fixed base 91. An annular plate 912 is fixedly installed at the end of the guide rod 911 away from the fixed base 91. A buffer spring 913 is sleeved on the outside of the guide rod 911. A guide plate 93 is provided on one side of the fixed base 91. The buffer spring 913 is located between the guide plate 93 and the annular plate 912. A movable hole 94 is provided in the middle of the guide plate 93. The guide rod 911 can pass through the movable hole 94 through the guide plate 93. A push plate 95 is fixedly installed on one side of the guide plate 93. A tail plate 96 is fixedly provided at the bottom of the rear end of the guide plate 93. The tail plate 96 is movable through the through slot 92 to facilitate the parallel displacement of the guide plate 93.

[0056] When cam 732 is not rotating (its protruding end is in position) Figure 4 When the cam 732 is in the direction of rotation, it does not contact the guide plate 93. When the cam 732 is driven to rotate (its protruding end is in the direction of rotation), the cam 732 is not in contact with the guide plate 93. Figure 5When the direction is reversed, cam 732 will slide into contact with one side of guide plate 93. At this time, guide plate 93 will be pushed to the side away from fixed seat 91. After limit plate 72 separates from large gear B52, guide plate 93 will move forward through push plate 95, causing push plate 95 to push large gear B52 to move closer to small gear B51 (when the two are in contact, and after large gear B52 is aligned and meshed with large gear A42, push plate 95 will press against and limit large gear B52). When the guide plate 93 deforms the compression buffer spring 913, the limiting plate 72 moves to one side of the large gear B52, the cam 732 will rotate synchronously. At this time, the protruding end of the cam 732 will gradually separate from the guide plate 93, and the buffer spring 913 will rebound the guide plate 93 and the push plate 95 away from the large gear B52. At this time, the large gear B52 is contacted and limited. Finally, the large gear B52 can be pulled away from the small gear B51, so that the large gear B52 is separated from the large gear A42.

[0057] Working principle: Before starting the device, first adjust the lifting roller 32 to rise. At this time, the lifting plate 61 moves upward synchronously. After the workpiece (thin copper frame) is placed in, the screw is rotated in the opposite direction to make the rectangular block 35 and the lifting roller 32 move downward until the lifting roller 32 descends and presses the workpiece. The workpiece will then be located between the upper and lower rollers. When the gap between the two rollers is less than 5cm, the servo motor drives the lower roller 31 to rotate. The pinion A41 and pinion B51 mesh first to realize the upper and lower rollers rotating synchronously in opposite directions, clamping the copper frame forward at a uniform speed. When the lifting plate 61 moves upward with the lifting roller 32, the connecting column 81 will slide downward toward the inclined slide groove 63. At this time, the connecting column 81 will pull the two symmetrically arranged positioning components 7 away from each other through the L-shaped rod 8, and the rack 723 can drive the positioning gear 731 to rotate forward. After roller 32 rises more than 5cm, positioning component 7 will completely separate from large gear B52, facilitating the displacement of large gear B52 and alignment with large gear A42. When the gluing roller 32 descends less than 5cm, large gear B52 can be moved away from small gear B51 in advance. At this time, connecting column 81 will slide upwards towards inclined slide groove 63. Subsequently, connecting column 81 will push the two symmetrically arranged positioning components 7 closer to each other through L-shaped rod 8 until one side of limit plate 72 is inserted between large gear B52 and small gear B51. At this time, rack 723 can drive positioning gear 731 to reverse. A connecting shaft 733 connects positioning gear 731 and cam 732. Positioning gear 731 can drive cam 732 to rotate synchronously through connecting shaft 733. When cam 732 does not rotate (its protruding end is in the position of the cam 732), the cam 732 will rotate synchronously. Figure 4 When the cam 732 is in the direction of rotation, it does not contact the guide plate 93. When the cam 732 is driven to rotate (its protruding end is in the direction of rotation), the cam 732 is not in contact with the guide plate 93. Figure 5When the direction is reversed, cam 732 will slide into contact with one side of guide plate 93. At this time, guide plate 93 will be pushed to move away from fixed seat 91. After limit plate 72 separates from large gear B52, guide plate 93 will move forward through push plate 95, causing push plate 95 to push large gear B52 to move towards small gear B51. At this time, guide plate 93 will compress buffer spring 913 and deform. When limit plate 72 moves to one side of large gear B52, cam 732 will rotate synchronously. At this time, the protruding end of cam 732 will gradually separate from guide plate 93, and buffer spring 913 will rebound guide plate 93 and push plate 95 away from large gear B52. At this time, large gear B52 is contacted and limited. Finally, large gear B52 can be pulled away from small gear B51 to separate large gear B52 from large gear A42.
