Description

Technical Field

[0001] This invention relates to the field of automated assembly technology for electronic components, and in particular to a processing equipment for a switching transformer PCB board. Background Technology

[0002] The switching transformer is the core component of a switching power supply. Its structure includes a magnetic core, frame, windings, and pins. During assembly, the pins need to be inserted into the corresponding holes on the PCB board to achieve electrical connection and mechanical fixation. Current transformer insertion machines use rigid grippers to pick up the transformer and use CCD vision recognition to take static pictures of the transformer and PCB board for positioning. After obtaining the position coordinates of the pins and holes, the machine controls a robotic arm to drive the grippers to insert the transformer into the PCB board along a preset trajectory.

[0003] Because switching transformers have a large number of pins, typically 4-8, there are cumulative manufacturing and assembly errors in the relative positions of each pin and the corresponding holes on the PCB. During insertion, some pins will contact the edge of the hole first, making the pin a fulcrum on the surface of the PCB, while other pins have not yet entered the hole. As insertion continues, the transformer will rotate or tilt. Since the rigid gripper cannot provide adaptive adjustment in the horizontal direction, this asynchronous insertion will cause pin bending or overall transformer posture shift. Furthermore, since the transformer core is large in size and tall, when its bottom shifts slightly, the lateral shift of the top core will be amplified, causing the core to affect or even collide with surrounding components. Therefore, this application provides a processing equipment for a switching transformer PCB board to meet the requirements. Summary of the Invention

[0004] The purpose of this invention is to provide a processing device for a switching transformer PCB board to solve the above-mentioned problems. By setting up a floating connector, a floating component and an alignment component, an adaptive floating compensation and a two-stage correction effect of secondary alignment can be formed during the insertion of transformer pins. This solves the problems mentioned in the background art, such as asynchronous insertion, pin bending and transformer tilting caused by cumulative errors between pins and holes, and collision of the top magnetic core with surrounding components caused by bottom offset.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A processing device for a switching transformer PCB board includes a machine body. The top of the machine body is provided with a PCB board conveyor belt for conveying PCB boards. A linear module that can move along the X and Z axes is fixedly connected to the top of the machine body. An insertion head is fixedly connected to the moving platform of the linear module. A drive assembly is provided inside the insertion head. A material picking head is installed at the drive end of the drive assembly for picking up the transformer and inserting it into the PCB board. A CCD camera is also provided at the bottom of the insertion head for preliminary positioning of the insertion hole. The material handling head includes a connector fixed to the drive end of the drive assembly. A bottom support is threaded to the bottom of the connector. A floating joint is sleeved between the connector and the bottom support, and an annular cavity is formed between the connector and the bottom support. A floating component is provided inside the floating joint, and the floating component is located inside the annular cavity. It also includes an automatic board feeder and a transformer feeder installed on both sides of the machine body. The output port of the automatic board feeder is adapted to the input port of the PCB board conveyor belt. The transformer feeder is provided in multiple sets for feeding different types of transformers.

[0006] Optionally, the drive assembly includes a bearing rotatably connected inside the insertion head, a hollow shaft slidably connected inside the bearing, and a connector fixedly connected to the bottom end of the hollow shaft. A lifting mechanism is provided on one side of the insertion head to drive the hollow shaft to move along the Y-axis, and a rotating mechanism is also provided on one side of the insertion head to drive the hollow shaft to rotate along the C-axis.

[0007] Optionally, the bottom of the floating joint is fixedly connected to a fixed seat, and the fixed seat is provided with an air chamber communicating with the hollow shaft. Sliders are symmetrically slidably connected inside the fixed seat, and grippers are fixedly connected to the bottom of both sliders. When the air is filled or released, the slider slides in the fixed seat to drive the grippers to pick up or release the transformer.

[0008] Optionally, a conical head is fitted on the outer side of the connector, and an annular ring is fitted on the outer side of the floating joint. An elastic element that drives the floating joint to reset is fixedly connected between the bottom wall of the conical head and the annular ring.

[0009] Optionally, the floating assembly includes a fixed ring fixed to the inner wall of the floating joint, and an airbag is fixedly connected to the inner wall of the fixed ring. Multiple sliding frames are equidistantly arranged along the axial direction on the inner side of the fixed ring, and the sliding frames can slide on the outer side of the fixed ring. First balls are symmetrically arranged inside the sliding frames, and the first balls contact the top wall and bottom wall of the annular cavity respectively.

[0010] Optionally, multiple straps are fixedly connected at equal intervals on the inner side of the airbag, and a hook is fixedly connected to the inner side of each sliding frame, with the hook inserted into the inner side of the strap. When the airbag is inflated or deflated, the sliding frame is driven to slide along the outer side of the fixed ring.

[0011] Optionally, the fixed ring has equidistant constraint grooves on both sides, and the sliding frame is symmetrically fixed with shaft pins, which slide inside the constraint grooves.

[0012] Optionally, the fixing ring has an air guide cavity on the side away from the airbag, and the fixing ring has multiple air inlets and outlets communicating with the air guide cavity for inflating and deflating the airbag.

[0013] Optionally, the slider is provided with an alignment component, which includes a shaped rod that slides inside the slider. The slider has an installation cavity inside. A disc body that slides and connects to the inner wall of the installation cavity is sleeved on the outside of the shaped rod. A nut that is threadedly connected to the installation cavity is rotatably provided on the outside of the shaped rod and above the disc body. A spring is sleeved between the disc body and the nut.

[0014] Optionally, the bottom of the irregular rod is threaded with an adjusting sleeve, and a second ball is rolled inside the adjusting sleeve. During the transformer pin insertion process, the second ball contacts the upper surface of the PCB board, driving the adjusting sleeve to move upward, so as to drive the irregular rod to slide upward until the top of the irregular rod contacts the conical surface of the conical head.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, the processing equipment for the switching transformer PCB board provided in this application, by setting up floating connectors, floating components and alignment components, can form an adaptive floating compensation and secondary alignment two-stage correction effect during the insertion of transformer pins. This can reduce the problems of asynchronous insertion, pin bending and transformer tilting caused by the cumulative error between pins and holes, while avoiding the risk of the top magnetic core colliding with surrounding components due to bottom offset. Furthermore, by setting a floating joint and floating component in the feeding head, when some pins first contact the edge of the hole and generate lateral force, the floating joint drives the transformer to move horizontally, so that all pins are aligned with their respective holes and inserted synchronously, thereby preventing pin bending and transformer rotation tilting. Based on the above, by setting an alignment component inside the slider, when a part of the pin is inserted, the second ball contacts the PCB board and pushes the irregular rod to slide up. Under the action of the radial force generated by the cooperation between the top of the irregular rod and the conical surface of the conical head, the picking head is pushed to be aligned twice, further reducing the remaining deviation and preventing the magnetic core from offset and colliding. It is worth mentioning that by controlling the inflation and deflation of the airbag to adjust the position of the sliding frame, the floating amount of the floating joint can be changed to quickly adapt to the processing requirements of different specifications of transformer plug-in.

[0025] like Figures 1 to 4 As shown, an embodiment of the present invention provides a processing equipment for a switching transformer PCB board, including a machine body 1. The top of the machine body 1 is provided with a PCB board conveyor belt 101 for conveying PCB boards. The PCB board conveyor belt 101 is a double belt structure, and its width can be adjusted according to the size of the PCB board (the specific structure adopts the prior art, which will not be described in detail here). A linear module 102 that can move along the X and Z axes is fixedly connected to the top of the machine body 1. An insertion head 103 is fixedly connected to the moving platform of the linear module 102. A drive assembly 5 is provided inside the insertion head 103. A pick-up head 4 is installed at the drive end of the drive assembly 5 for clamping the transformer and inserting it into the PCB board. A CCD camera 8 is also provided at the bottom of the insertion head 103 for preliminary positioning of the insertion hole. The linear module 102 is composed of two sets of linear drive mechanisms. Both sets of linear drive mechanisms are driven by a lead screw module and a servo motor to drive the insertion head 103 and the pick-up head 4 to move, so as to achieve precise positioning of the transformer pins and the PCB board insertion holes. It also includes an automatic board feeder 2 and a transformer feeder 3 set on both sides of the machine body 1. The output port of the automatic board feeder 2 is adapted to the input port of the PCB board conveyor belt 101 and is used to automatically feed the PCB board into the PCB board conveyor belt 101. The automatic board feeder (2) adopts the structure of the automatic board feeding machine in the prior art, including the lifting hopper and the pushing mechanism, which will not be described in detail here. The transformer feeder 3 is set with multiple sets for feeding different types of transformers. Each set of feeders includes a material box and a straight vibration track, and outputs the transformer with the pins facing down. In this embodiment, as Figure 5As shown, the drive assembly 5 includes a bearing 51 rotatably connected in the insertion head 103. A hollow shaft 52 is slidably connected inside the bearing 51. A keyway is provided inside the bearing 51. A key that cooperates with the keyway is provided on the outside of the hollow shaft 52 to ensure that the hollow shaft 52 can slide inside the bearing 51 and drive the material taking head 4 to rotate with the rotation of the bearing 51. The connecting head 41 is fixedly connected to the bottom end of the hollow shaft 52. A lifting mechanism 53 is provided on one side of the insertion head 103 to drive the hollow shaft 52 to move along the Y-axis. The lifting mechanism (53) can be a cylinder or a servo motor with a screw structure. In this embodiment, a servo motor with a synchronous belt drive is used (existing technology, which will not be explained in detail here). A rotating mechanism 54 is also provided on one side of the insertion head 103 to drive the hollow shaft 52 to rotate along the C-axis. The rotating mechanism 54 uses a servo motor with a synchronous belt drive to drive the material taking head 4 to rotate, which facilitates the picking and placing of the transformer. In this embodiment, as Figure 6 , Figure 7 and Figure 9 As shown, the feeding head 4 includes a connector 41 fixed to the driving end of the driving assembly 5, i.e., the bottom end of the hollow shaft 52, which serves as the mounting base for the feeding head 4. The bottom of the connector 41 is threadedly connected to a base support 43. The threaded connection of the base support 43 facilitates the disassembly and maintenance of the floating connector 45 and the floating assembly 6. A floating connector 45 is sleeved between the connector 41 and the base support 43, which can float within a certain range relative to the connector 41 and the base support 43. This allows the transformer to automatically align during insertion, compensates for the positional deviation between the pin and the hole, and reduces the pin bending or transformer tilting caused by rigid insertion. An annular cavity 44 is formed between the connector 41 and the base support 43. A floating assembly 6 is provided inside the floating connector 45, and the floating assembly 6 is located inside the annular cavity 44. The annular cavity 44 not only provides installation space for the floating assembly 6 but also limits the range of motion of the floating connector 45, preventing excessive movement from causing complete pin misalignment. Furthermore: a conical head 42 is sleeved on the outer side of the connector 41, and an annular ring is sleeved on the outer side of the floating connector 45. An elastic element 46 (preferably a compression spring) is fixedly connected between the bottom wall of the conical head 42 and the annular ring to drive the floating connector 45 to reset. The elastic element 46 can push the floating connector 45 back to the center position after floating ends, ensuring that the gripper 49 is in the initial position and posture when picking up materials next time, and avoiding material picking failure due to accumulated deviation. Based on this: the bottom of the floating connector 45 is fixedly connected to a fixed base 47, and the fixed base 47 is provided with an air chamber communicating with the hollow shaft 52. Slider 48 is symmetrically slidably connected inside the fixed base 47. The bottom of each slider 48 is fixedly connected to a gripper 49. When filling or defilling, the slider 48 slides in the fixed base 47 to drive the gripper 49 to grip or release the transformer. The hollow shaft 52 is hollow inside as an air passage, and its top end is connected to the air supply equipment through a rotary joint. With this design, there is no need for an external air pipe to follow, which can avoid the risk of air pipe entanglement and bending. At the same time, at least one sealing ring is provided between the bottom support 43 and the fixed base 47 to prevent gas from leaking from the gap, so as to ensure the accuracy of the gripper 49's movement.

[0026] In this embodiment, as Figure 10 and Figure 11 As shown, the floating assembly 6 includes a fixed ring 61 fixed to the inner wall of the floating joint 45, and an airbag 62 is fixedly connected to the inner wall of the fixed ring 61. Multiple sliding frames 63 are equidistantly arranged along the axial direction on the inner side of the fixed ring 61, and the sliding frames 63 can slide on the outer side of the fixed ring 61. First balls 64 are symmetrically arranged inside the sliding frames 63, and the first balls 64 contact the top and bottom walls of the annular cavity 44 respectively. Because transformers of different specifications have different numbers of pins, pin diameters, pin spacing, and core sizes, the required... The horizontal floating compensation amount is also different. Therefore, in this embodiment, the radial position of multiple sliding frames 63 is adjusted by controlling the inflation and deflation of the airbag 62, thereby realizing the adjustment of the horizontal floating amount of the floating joint 45. When the airbag 62 is inflated, it pushes the sliding frame 63 to slide inward towards the center. The diameter of the circle enclosed by the multiple sliding frames 63 becomes smaller, and the floating amount decreases. Conversely, when the diameter of the circle enclosed by the airbag 62 increases, the floating amount increases. Through this design, the floating amount can be quickly adjusted according to the specifications of the current transformer to adapt to different models of switching transformers.

[0027] Furthermore: multiple straps 621 are fixedly connected at equal intervals on the inner side of the airbag 62, and a hook 631 is fixedly connected on the inner side of each sliding frame 63. The hook 631 is inserted into the inner side of the strap 621. When the airbag 62 is inflated or deflated, it drives the sliding frame 63 to slide along the outer side of the fixed ring 61. With the cooperation of the straps 621 and the hooks 631, the sliding frame 63 can slide radially on the outer side of the fixed ring 61 as the airbag 62 is inflated or deflated, so as to realize the rapid and precise adjustment of the floating amount and improve the versatility and production efficiency of the equipment. The fixed ring 61 has equal-distance constraint grooves 611 on both sides. The sliding frame 63 is symmetrically fixed with shaft pins, and the shaft pins slide inside the constraint grooves 611. The cooperation between the constraint grooves 611 and the shaft pins limits the movement direction of the sliding frame 63, so that it can only slide along the axial direction of the fixed ring 61 and will not deflect or tilt, thereby ensuring that the first ball 64 always maintains good contact with the top and bottom walls of the annular cavity 44. An air guide cavity 612 is provided on the side of the fixing ring 61 away from the airbag 62, and multiple air inlets and outlets 613 communicating with the air guide cavity 612 are provided in the fixing ring 61 for inflating and deflating the airbag 62. The air guide cavity 612 serves as a gas distribution channel, which can introduce external air sources into each air inlet and outlet 613 to achieve rapid and uniform inflation and deflation of the airbag 62. The multiple air inlets and outlets 613 are evenly distributed in the circumferential direction, which can ensure that each sliding frame 63 is subjected to uniform force when the airbag 62 inflates.

[0028] In this embodiment, as Figures 6 to 8 As shown, the slider 48 is internally equipped with an alignment component 7, which includes a shaped rod 71 that slides inside the slider 48. The slider 48 has an internal mounting cavity 72. A disc body is fitted around the shaped rod 71 and slidably connected to the inner wall of the mounting cavity 72. A nut, threadedly connected to the mounting cavity 72, is rotatably mounted on the outside of the shaped rod 71 and above the disc body. A spring 73 is fitted between the disc body and the nut. Optionally, an adjusting sleeve 74 is threadedly connected to the bottom of the shaped rod 71, and a second ball bearing 75 rolls within the adjusting sleeve 74. Rotating the adjusting sleeve 74 adjusts the distance between the second ball bearing 75 and the clamping jaw 49 to accommodate different transformer insertion requirements. During the process, the second ball bearing 75 contacts the upper surface of the PCB board, causing the adjusting sleeve 74 to move upward, thereby driving the shaped rod 71 to slide upward until the top of the shaped rod 71 contacts the conical surface of the conical head 42. The conical head 42 is an inverted cone shape with a larger top and a smaller bottom. The top of the shaped rod 71 is set as an inclined surface that cooperates with the conical head 42. When the top of the shaped rod 71 contacts the conical surface of the conical head 42, a contact force is generated between the two. If there is a slight angular or positional deviation of the transformer, the conical surface of the conical head 42 will convert the upward linear motion of the shaped rod 71 into a radial force, pushing the floating joint 45, the fixed seat 47, the slider 48, and the clamp 49 to align, so that the transformer is in the center position when it is installed.

[0029] Working principle of the invention: Automatic board feeder 2 feeds the PCB board into PCB board conveyor belt 101. At this time, PCB board conveyor belt 101 transports the PCB board to the insertion station. CCD camera 8 takes preliminary pictures of the insertion holes on the PCB board to obtain the coordinate information of the hole positions. Then, transformer feeder 3 feeds the switching transformer with the pins facing down to the picking position. The linear module 102 drives the insertion head 103 to move above the picking position. The lifting mechanism 53 drives the hollow shaft 52 to descend so that the picking head 4 is close to the transformer. Air is injected into the air chamber in the fixed seat 47 through the air passage inside the hollow shaft 52, pushing the slider 48 to slide and driving the gripper 49 to close and clamp the transformer. If the angle needs to be adjusted, the rotating mechanism 54 drives the hollow shaft 52 to rotate so that the picking head 4 drives the transformer to rotate to the correct position. The linear module 102 drives the insertion head 103 to move above the PCB board insertion station. The CCD camera 8 reconfirms the insertion hole position. Then, the lifting mechanism 53 drives the picking head 4 to descend and insert the transformer pins into the PCB board holes. When one pin of the transformer contacts the edge of the hole before the other pins, a fulcrum is formed on the PCB board surface. When the transformer is subjected to lateral force due to the pin contacting the edge of the hole, the lateral force is transmitted to the floating connector 45, causing it to move horizontally relative to the connector 41 and the base support 43. At the same time, the first ball 64 rolls on the top and bottom walls of the annular cavity 44 to reduce frictional resistance and ensure the sensitivity of the horizontal movement of the floating connector 45. This drives the gripper 49 and the clamped transformer to finely adjust their positions in the horizontal plane so that all pins are aligned with their respective holes. As the picking head 4 continues to descend, all pins are synchronously inserted into the PCB board holes. like Figure 7 As shown, when the pin is inserted about halfway, the second ball 75 contacts the upper surface of the PCB board. Since the second ball 75 is rolled inside the adjusting sleeve 74, as the pick-up head 4 descends further, the second ball 75 and the adjusting sleeve 74 push the shaped rod 71 to slide upward in the mounting cavity 72 inside the slider 48. At the same time, the spring 73 is compressed. When the top of the shaped rod 71 contacts the conical surface of the conical head 42, the pick-up head 4 continues to press down. The conical surface of the conical head 42 applies an outward radial force to the top of the shaped rod 71. At the same time, the shaped rod 71 transmits the force in the opposite direction to the slider 48, the fixed seat 47 and the entire floating joint 45, pushing the pick-up head 4 and the transformer to perform secondary alignment in the horizontal direction, eliminating the small deviation after the previous floating compensation. When installing switching transformers of different specifications, the floating amount is adjusted by controlling the inflation and deflation of the airbag 62. When the airbag 62 is inflated, the strap 621 and hook 631 drive the sliding frame 63 to slide radially inward along the fixed ring 61. The diameter of the circle enclosed by the multiple sliding frames 63 becomes smaller, and the horizontal floating amount of the floating joint 45 decreases. When the airbag 62 deflates and contracts, the floating amount increases, thereby quickly adapting to transformers with different pin numbers, diameters and core sizes. During the continuous downward pressure, the interaction between the conical head 42 and the irregular rod 71 maintains the centering force, ensuring that the central axis of the transformer core coincides with the central axis of the PCB board insertion array, preventing collisions with surrounding components due to the top core offset. After the transformer pins are fully inserted into the PCB board, the air passage is depressurized, the slider 48 slides in the reverse direction, the gripper 49 opens to release the transformer, the lifting mechanism 53 drives the picking head 4 to rise, the elastic element 46 pushes the floating connector 45 back to the center position, the irregular rod 71 of the alignment component 7 is reset under the action of the spring 73, the second ball 75 leaves the PCB board surface, and after the insertion of one transformer is completed, the PCB board conveyor belt 101 sends the next PCB board into the insertion station. The equipment repeats the above steps to achieve continuous automated production.
