Description

Technical Field

[0001] This application belongs to the field of transformer insertion and installation technology, and in particular relates to a transformer insertion machine. Background Technology

[0002] Transformers are typically mounted on circuit boards. During the installation of transformers, manual insertion is usually used, where the transformer pins are directly inserted into the corresponding fixed terminals on the circuit board. However, transformer pins are prone to deformation upon arrival, so they need to be manually shaped before being inserted into the circuit board. On the one hand, manual insertion is inefficient; on the other hand, the need for manual pin shaping further reduces the efficiency of manual transformer insertion, thus severely reducing the production efficiency of the circuit board.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0047] like Figures 1-9 As shown, in one embodiment of this application, a transformer insertion machine 100 is provided for inserting the pins of a transformer 91 into the corresponding fixed terminals on a circuit board 92 to realize the insertion and installation of the transformer 91; the circuit board 92 may be a lamp board, a driver board, a control board, or other types of circuit boards 92, which are not limited here.

[0048] Combination Figure 2 and Figure 3As shown, the transformer insertion machine 100 provided in this embodiment includes a frame 10, a conveying device 20, a feeding device 30, a shaping device 40, a positioning device 50, a picking device 60, and an insertion device 70. The frame 10 serves as the mounting base for each device, providing fixed support. The conveying device 20 is connected to the frame 10 and is used to convey the circuit board 92. It is understood that the conveying device 20 can drive the circuit board 92 to move in a certain direction to realize the transportation of the circuit board 92. The feeding device 30 is located on the side of the frame 10 and is used to provide transformers. 91; The shaping device 40 is connected to the frame 10 and located between the conveying device 20 and the feeding device 30, and is used to shape the pins of the transformer 91; it can be understood that the shaping device 40 can bend the deformed transformer 91 pins to a normal shape so that the subsequent insertion device 70 can accurately insert the pins of the transformer 91 into the corresponding fixed terminals of the circuit board 92; it should be noted that the shaping device 40 adopts a relatively mature transformer 91 pin shaping device 40 on the market, and the structure and working principle of the shaping device 40 will not be described in detail here. The positioning device 50 is connected to the frame 10 and located between the conveying device 20 and the shaping device 40, and is used to position the shaped transformer 91; the material handling device 60 is connected to the frame 10 and located between the feeding device 30 and the conveying device 20, and can move the transformer 91 output by the feeding device 30 into the shaping device 40 and can move the shaped transformer 91 into the positioning device 50; the insertion device 70 is connected to the frame 10 and is used to insert the transformer 91 at the positioning device 50 onto the circuit board 92 conveyed by the conveying device 20.

[0049] In the transformer insertion machine 100 of this application embodiment, during operation, the circuit board 92 is placed on the conveying device 20 for conveying. At the same time, the picking device 60 moves the transformer 91 provided by the feeding device 30 into the shaping device 40 for shaping. After shaping, the transformer 91 is moved by the picking device 60 to the positioning device 50 for positioning. Meanwhile, the circuit board 92 is conveyed to a certain position on the conveying device 20, and the insertion device 70 inserts the positioned transformer 91 into the circuit board 92. Finally, the circuit board 92 with the transformer 91 inserted is automatically conveyed by the conveying device 20 to the next process. In this way, the automatic feeding, automatic shaping and automatic insertion process of the transformer 91 is realized. The transformer insertion machine 100 of this application embodiment, with the coordinated cooperation of the conveying device 20, the feeding device 30, the shaping device 40, the positioning device 50, the picking device 60 and the insertion device 70, can realize the integrated automated operation of feeding, shaping and inserting transformer 91. Compared with the existing manual insertion, the shaping and insertion efficiency of transformer 91 can be effectively improved, thereby improving the production efficiency of circuit board 92.

[0050] In this embodiment, combined with Figure 2 As shown, a support platform 11 is provided on the frame 10. The feeding device 30 is located on the left side of the support platform 11, and the conveying device 20 is installed on the right side of the support platform 11 and distributed along the front-to-back direction. The material handling device 60 is installed on the support platform 11 and is distributed laterally between the feeding device 30 and the conveying device 20. Figure 3 As shown, the shaping device 40 and the positioning device 50 are located below the material handling device 60 and are arranged at intervals along the direction from the feeding device 30 to the conveying device 20. This layout is beneficial for the installation and arrangement of the devices and components.

[0051] In this embodiment, combined with Figure 2 and Figure 3 As shown, the feeding device 30 includes a feeding rack 31, a vibratory plate 32 and a linear vibrator 33 mounted on the feeding rack 31. The feeding rack 31 is located on the side of the frame 10. The linear vibrator 33 and the vibratory plate 32 are sequentially connected along the front-to-back direction. During operation, the operator pours the disordered transformers 91 into the vibratory plate 32. Under the vibration of the vibratory plate 32, the transformers 91 are neatly and orderly fed into the linear vibrator 33 one by one (the transformers 91 are neatly and orderly fed into the linear vibrator 33 with their pins facing down). Then, the linear vibrator 33 neatly and orderly discharges the transformers 91 to facilitate the material handling device 60. In conjunction with... Figure 1 As shown, the feeding rack 31 is provided with an outer cover 34 covering the vibratory plate 32 and the direct vibrator 33. The outer cover 34 protects the vibratory plate 32 and the direct vibrator 33, ensuring the stable and safe operation of the transformer 91 feeding. The top of the outer cover 34 is provided with a first opening and closing door assembly 35 to facilitate the placement of the transformer 91 into the vibratory plate 32.

[0052] In this embodiment, combined with Figure 2 and Figure 3 As shown, both the bottom of the frame 10 and the bottom of the feeding rack 31 are provided with support legs 15 to support and fix the entire transformer insertion machine 100.

[0053] In this embodiment, combined with Figure 1 and Figure 2 As shown, a baffle plate 12 is provided around the frame 10. The baffle plate 12 encloses the shaping device 40, positioning device 50, material handling device 60 and insertion device 70 in a relatively enclosed space, which protects the shaping device 40, positioning device 50, material handling device 60 and insertion device 70 and ensures the safe and efficient operation of the transformer 91 during shaping and insertion. In addition, a second opening and closing door assembly 13 is also provided on the frame 10 to facilitate the maintenance and monitoring of the shaping device 40, positioning device 50, material handling device 60 and insertion device 70.

[0054] In this embodiment, the frame 10 is also equipped with a control device, a first detection sensor for monitoring the position of the transformer 91, and a second detection sensor for monitoring the position of the circuit board 92. The first detection sensor, the second detection sensor, the conveying device 20, the feeding device 30, the shaping device 40, the positioning device 50, the picking device 60, and the insertion device 70 are all electrically connected to the control device. After the first detection sensor and the second detection sensor detect the position signals of the transformer 91 and the circuit board 92, they feed the signals back to the control device. The control device drives the conveying device 20, the feeding device 30, the shaping device 40, the positioning device 50, the picking device 60, and the insertion device 70 to work together in coordination, thereby realizing the precise automatic feeding, automatic shaping, and automatic insertion operation of the transformer 91, and improving the insertion efficiency of the transformer 91. The control device can be a technically mature PLC controller or a computer or other devices capable of control, and is not limited here. In addition, the first detection sensor and the second detection sensor can be fiber optic sensors or proximity switches or other sensors capable of detecting position, and are not limited here. In other embodiments, the operating speed and operating sequence of the conveying device 20, the feeding device 30, the shaping device 40, the positioning device 50, the picking device 60 and the insertion device 70 can also be set according to actual needs, so as to realize the precise automatic feeding, automatic shaping and automatic insertion operation of the transformer 91.

[0055] In another embodiment of this application, combined with Figure 2 and Figure 4 As shown, the provided transformer insertion machine 100 also includes a positioning fixture 80 disposed at the discharge port of the feeding device 30. The positioning fixture 80 includes a positioning fixing frame 81, a blocking plate 82 and a pressure plate 83 connected to the positioning fixing frame 81. The positioning fixing frame 81 is connected to the frame 10. The positioning fixing frame 81 forms a slide groove 811 for the transformer 91 to slide. One end of the slide groove 811 is connected to the discharge port of the feeding device 30. The blocking plate 82 is disposed at the other end of the slide groove 811 and is used to block the transformer 91. The pressure plate 83 is located between the blocking plate 82 and the feeding device 30 and is located above the slide groove 811. The pressure plate 83 and the blocking plate 82 are spaced apart and form a receiving position for accommodating a transformer 91. Specifically, the transformer 91 output by the feeding mechanism enters the slide 811 and is conveyed forward along the slide 811. When the transformer 91 is conveyed to the receiving position, the material taking device 60 takes away the transformer 91. At the same time, the transformer 91 adjacent to the rear of the transformer 91 will be blocked by the pressure plate 83, so that it will not be carried out of the slide 811 by the transformer 91, thereby reducing the material taking loss of the transformer 91 and reducing the manufacturing cost.

[0056] In this embodiment, combined with Figure 2 and Figure 4As shown, the pressure plate 83 is L-shaped. The lower end of the vertical section of the pressure plate 83 is connected to the positioning and fixing frame 81. The horizontal section of the pressure plate 83 is set above the slide 811, and the distance between the horizontal section of the pressure plate 83 and the slide 811 is less than the height of the transformer 91. In this way, when the material handling device 60 removes the transformer 91 from the receiving position, the next transformer 91 will move upward due to the driving force of the first transformer 91. After the transformer 91 moves upward a certain distance, it will be blocked by the horizontal section and fall back into the slide 811. Moreover, the distance between the horizontal section of the pressure plate 83 and the slide 811 is less than the height of the transformer 91. This ensures that the transformer 91 will not fall out of the slide 811 when it moves upward, so that the transformer 91 can fall stably and in a preset posture into the slide 811 during the fall, which facilitates subsequent material handling.

[0057] In this embodiment, combined with Figure 2 and Figure 4 As shown, a magnetic sensor is installed inside the positioning and fixing frame 81. The magnetic sensor is used to sense whether there is a transformer 91 in the receiving position. If there is a transformer 91, the material picking device 60 is triggered to pick up the material. If there is no transformer 91, the material picking device 60 is not triggered, ensuring that the material picking device 60 picks up the material accurately and improving the operating efficiency.

[0058] In another embodiment of this application, combined with Figure 2 and Figure 5 As shown, the material handling device 60 of the provided transformer insertion machine 100 includes a linear module 61, a first lifting cylinder 62, and a first transformer gripper 63 and a second transformer gripper 64 for gripping the transformer 91. The linear module 61 is connected to the frame 10. The material handling device 60 also includes a material handling fixing frame 68, which is mounted on the support platform 11. The linear module 61 is mounted on the material handling fixing frame 68. The drive end of the linear module 61 is connected to the first lifting cylinder 62. The first transformer gripper 63 and the second transformer gripper 64 are both connected to the piston rod of the first lifting cylinder 62 and are both located above the shaping device 40. The linear module 61 is used to drive the first lifting cylinder 62 to move back and forth between the feeding device 30 and the conveying device 20, so that the first transformer gripper 63 moves back and forth between the feeding device 30 and the shaping device 40, and the second transformer gripper 64 moves back and forth between the shaping device 40 and the positioning device 50.

[0059] Specifically, when the material handling device 60 needs to handle material, the linear module 61 drives the first lifting cylinder 62 to move towards the feeding device 30; when the first transformer gripper 63 and the second transformer gripper 64 move to the discharge point of the feeding device 30 and above the shaping device 40 respectively, the first lifting mechanism drives the first transformer gripper 63 and the second transformer gripper 64 to move downwards; when the first transformer gripper 63 and the second transformer gripper 64 move downwards to a certain position, the first transformer gripper 63 grips the transformer 91 output by the feeding device 30, and the second transformer gripper 64 grips the transformer 91 after shaping; then, the linear module 61 drives the first lifting cylinder 62, the first transformer gripper 63 and the second transformer gripper 64 to move towards the conveying device 20, and when the first transformer gripper 63 moves to the top of the shaping device 40, and the second transformer gripper 64 moves... When the transformer 91 reaches above the positioning device 50, the first lifting cylinder 62 drives the first transformer gripper 63 and the second transformer gripper 64 to move downwards. After the first transformer gripper 63 and the second transformer gripper 64 have moved down to a certain position, the first transformer gripper 63 places the clamped transformer 91 at the shaping device 40 for shaping, and the second transformer gripper 64 places the clamped transformer 91 at the positioning device 50 for positioning. Finally, the linear module 61 and the first lifting cylinder 62 are reset, which facilitates the next loading of the transformer 91. During this process, the linear module 61 drives the first transformer gripper 63 and the second transformer gripper 64 to move once, which can realize the movement of the transformer 91 at the feeding device 30 to the shaping device 40 and the movement of the transformer 91 shaped by the shaping device 40 to the positioning device 50. It has high operating efficiency and stable and reliable operation.

[0060] In another embodiment of this application, combined with Figure 5 As shown, the material handling device 60 of the provided transformer insertion machine 100 further includes a first connecting frame 65, two connecting components 66, and two first connecting plates 67. The piston rod of the first lifting cylinder 62 is connected to the first connecting frame 65. The first transformer gripper 63 and the second transformer gripper 64 are respectively installed on the two first connecting plates 67. The two first connecting plates 67 are respectively connected to the first connecting frame 65 through the two connecting components 66. Each of the two connecting components 66 includes a first fastener 661 and a first elastic element 662. The first connecting frame 65 and the first connecting plate 67 are connected to the first connecting frame 65. The connecting plate 67 is slidably connected via the first fastener 661, and the first connecting plate 67 can slide up and down relative to the first connecting frame 65; the first elastic member 662 is sleeved on the outside of the first fastener 661, and the two ends of the first elastic member 662 abut against the first connecting frame 65 and the first connecting plate 67 respectively; the connecting assembly 66 also includes a first detection member 663 for detecting the distance between the first connecting plate 67 and the first connecting frame 65, and the linear module 61, the first lifting cylinder 62 and the first transformer gripper 63 are all electrically connected to the first detection member 663.

[0061] Specifically, during the process of the first lifting cylinder 62 driving the first transformer gripper 63 to move downwards and inserting the leads of the transformer 91 into the shaping device 40 for shaping, if the leads of the transformer 91 are significantly deformed, they cannot be inserted into the shaping device 40. At this time, as the first lifting cylinder 62 continues to move downwards, it pushes the first connecting plate 67 connected to the first transformer gripper 63 to move upwards relative to the first connecting frame 65. This causes a change in the distance between the first connecting plate 67 and the second connecting frame 73. When the distance exceeds a preset value, [the following occurs]. The first detection element 663 is triggered, and the first detection element 663 sends a feedback signal to the linear module 61, the first lifting cylinder 62, and the first transformer gripper 63, thereby controlling the linear module 61 and the first lifting cylinder 62 to drive the first transformer gripper 63 to move, so as to remove the transformer 91 with large pin deformation from the shaping device 40 for material discharge. In this way, the transformer 91 with large pin deformation can be identified and discharged using the material handling device 60. This allows the unqualified transformer 91 to be directly discharged, thereby ensuring that the subsequent transformer 91 shaping operation is carried out efficiently and quickly. Similarly, during the process of placing the pins of the transformer 91 into the positioning device 50, if the pins of the transformer 91 do not conform to the preset shape after shaping, the pins of the transformer 91 cannot be inserted into the positioning device 50. At this time, as the first lifting cylinder 62 continues to move downward, it pushes the first connecting plate 67 connected to the second transformer clamp 64 to move upward relative to the first connecting frame 65. At this time, the distance between the first connecting plate 67 and the second connecting frame 73 changes. When the distance value is greater than the preset value, the first detection element 663 is triggered. The first detection element 663 feeds back a signal to the linear module 61, the first lifting cylinder 62 and the second transformer clamp 64, thereby controlling the linear module 61 and the first lifting cylinder 62 to drive the second transformer clamp 64 to move, so as to remove the pins with large deformations from the positioning device 50 and perform material discharge. In this way, the transformer 91 that is not shaped properly can be directly discharged, thereby ensuring that the subsequent transformer 91 insertion operation is carried out efficiently and quickly. In addition, since a first elastic element 662 is provided between the first connecting plate 67 and the first connecting frame 65, the first elastic element 662 will provide an upward resistance to the first connecting plate 67 during the process of inserting the pins of the transformer 91 into the shaping device 40. This resistance overcomes the resistance of inserting the pins of the transformer 91 into the shaping device 40 or the resistance of inserting the transformer 91 with small pin deformation into the shaping device 40, ensuring that the insertion of the transformer 91 with no pin deformation or small deformation into the shaping device 40 will not cause the first connecting plate 67 to move upward, thus preventing the material handling device 60 from accidentally discharging material.

[0062] In this embodiment, the first connecting frame 65 is provided with a sliding hole. The first fastener 661 passes through the sliding hole and the elastic element and is fixedly connected to the first connecting plate 67. The inner diameter of the sliding hole is larger than the outer diameter of the first fastener 661, so that the first fastener 661 can move up and down in the sliding hole. This realizes the up and down movement of the first connecting plate 67 relative to the first fixed frame. At the same time, the upper end of the first fastener 661 abuts against the upper surface of the first connecting frame 65, thereby preventing the first fastener 661 from coming out of the sliding hole and ensuring the stable and reliable operation of the entire device. Specifically, the first fastener 661 can be a nut, bolt, or screw.

[0063] In this embodiment, a vertically arranged linear guide slider 24 is also connected between the first connecting frame 65 and the first connecting plate 67, and the linear guide slider 24 provides guidance for the up and down movement of the first connecting plate 67, thereby improving the stability and reliability of the movement of the first connecting plate 67.

[0064] In this embodiment, the first detection element 663 is a proximity switch or displacement sensor, or other components capable of detecting distance. The first elastic element 662 is a spring, elastic sleeve, or other component with a certain degree of elasticity.

[0065] In this embodiment, combined with Figure 4 As shown, the positioning and fixing frame 81 is equipped with a first defective product box 84, which is located between the baffle plate 82 and the shaping device 40. When the first detection element 663, connected to the first transformer gripper 63, detects severe deformation of the transformer 91's pins, the first detection element 663 controls the linear module 61 to drive the first transformer gripper 63 to move towards the first defective product box 84. When the first transformer gripper 63 moves above the first defective product box, it releases the transformer 91, and the transformer 91 falls into the first defective product box for collection. Figure 3 As shown, a second defective product box 14 is provided on the support platform 11. The second defective product box 14 is located between the positioning device 50 and the shaping device 40. When the first detection element 663 connected to the second transformer gripper 64 detects that the pins of the transformer 91 are severely deformed, the first detection element 663 controls the linear module 61 to drive the second transformer gripper 64 to move toward the second defective product box. When the second transformer gripper 64 moves above the second defective product box 14, the second transformer gripper 64 releases the transformer 91, and the transformer 91 falls into the second defective product box 14 for collection.

[0066] In another embodiment of this application, combined with Figure 3 and Figure 6As shown, the positioning device 50 of the provided transformer insertion machine 100 includes a positioning bracket 51 and a first positioning plate 212. The positioning bracket 51 is connected to the frame 10 and is mounted on the support platform 11. The first positioning plate 212 is mounted on the positioning bracket 51 and has positioning holes 521 for inserting the pins of the transformer 91. Specifically, the positioning bracket 51 serves as the mounting base for the first positioning plate 212, supporting and fixing the first positioning plate 212. The shaped transformer 91 is moved to the first positioning plate 212 by the material handling device 60, and the pins of the transformer 91 are inserted into the positioning holes 521 on the first positioning plate 212. This achieves accurate positioning of the transformer 91, ensuring good posture consistency of the transformer 91 picked up by the subsequent insertion device 70, guaranteeing efficient operation of subsequent insertion operations, and improving insertion efficiency and accuracy. This positioning method, which uses the pins of the transformer 91 to insert into the positioning holes 521, has a simple positioning structure and is convenient and quick to operate.

[0067] In another embodiment of this application, combined with Figure 3 and Figure 7 As shown, the transformer insertion machine 100 includes a insertion device 70 comprising a robotic arm 71 and a third transformer gripper 72 for gripping a transformer 91. The robotic arm 71 is connected to the frame 10, and the third transformer gripper 72 is connected to the end of the robotic arm 71. Specifically, the robotic arm 71 can drive the third transformer gripper 72 to move at any position in three-dimensional space. In this way, it is easy to control the first transformer gripper 63 to first remove the transformer 91 from the positioning device 50, and then insert the transformer 91 into the circuit board 92 conveyed on the conveying device 20. The entire action can be performed quickly and the insertion accuracy of the transformer 91 is very high.

[0068] In this embodiment, the plug-in device 70 also includes a plug-in mounting bracket, which is mounted on the conveying device 20. The robot arm 71 is fixed on the plug-in mounting bracket, so that the robot arm 71 drives the third transformer gripper 72 to move above the conveying device 20, avoiding interference.

[0069] In another embodiment of this application, combined with Figure 7As shown, the end of the robotic arm 71 of the provided transformer insertion machine 100 is connected to a second connecting frame 73, and the third transformer gripper 72 is connected to a second connecting plate 74; the insertion device 70 also includes a second fastener 75 and a second elastic member 76. The second connecting frame 73 and the second connecting plate 74 are slidably connected by the second fastener 75, and the second connecting plate 74 can slide up and down relative to the second connecting frame 73; the second elastic member 76 is sleeved on the second fastener 75, and the two ends of the second elastic member 76 abut against the second connecting frame 73 and the second connecting plate 74 respectively; the insertion device 70 also includes a second detection element 77 for detecting the distance between the second connecting plate 74 and the second connecting frame 73. The robotic arm 71 and the third transformer gripper 72 are both electrically connected to the second detection element 77.

[0070] Specifically, during the process of inserting the transformer 91, which is gripped by the third transformer gripper 72, into the corresponding fixed terminal of the circuit board 92, if the pins of the transformer 91 are severely deformed, the robot arm 71 drives the third transformer gripper 72 to move downward, thereby pushing the second connecting plate 74 relative to the second connecting frame 73 to move upward. This causes a change in the distance between the second connecting plate 74 and the second connecting frame 73. When the distance value is greater than the preset value, the second detection element 77 is triggered. The second detection element 77 feeds back a signal to the robot arm 71 and the third transformer gripper 72, and controls the robot arm 71 to drive the third transformer gripper 72 to move out of the conveying device 20 and perform material discharge. This allows unqualified transformers 91 to be directly discharged, ensuring that subsequent transformer 91 insertion operations are carried out efficiently and quickly. In addition, since a second elastic element 76 is provided between the second connecting plate 74 and the second connecting bracket 73, the second elastic element 76 will provide an upward resistance to the second connecting plate 74 during the process of inserting the pins of the transformer 91 into the circuit board 92. This resistance can overcome the resistance of inserting the pins of the transformer 91 into the circuit board 92 or the resistance of inserting the transformer 91 with small pin deformation into the circuit board 92, ensuring that the distance between the second connecting plate 74 and the second connecting bracket 73 is within the preset range, and will not trigger the second detection element 77, ensuring that the qualified transformer 91 is smoothly inserted into the circuit board 92 and avoiding mis-discharge.

[0071] In this embodiment, the second detection element 77 is a proximity switch or displacement sensor, or other components capable of detecting distance. The second elastic element 76 is a spring, elastic sleeve, or other component with a certain degree of elasticity.

[0072] In this embodiment, a vertically arranged linear guide slider 24 is also connected between the second connecting frame 73 and the second connecting plate 74, and the linear guide slider 24 provides guidance for the up and down movement of the second connecting plate 74, thereby improving the stability and reliability of the movement of the second connecting plate 74.

[0073] In another embodiment of this application, combined with Figure 3 and Figure 8 As shown, the conveying device 20 of the provided transformer insertion machine 100 includes a positioning mechanism 21 and two belt conveyor mechanisms 22. Both belt conveyor mechanisms 22 are connected to the frame 10 and are arranged parallel to each other. The positioning mechanism 21 is located between the two belt conveyor mechanisms 22 and is used to position the circuit board 92 conveyed by the belt conveyor mechanisms 22. Specifically, the circuit board 92 is placed on the two belt conveyor mechanisms 22 on opposite sides, so that the circuit board 92 is conveyed forward under the drive of the belt conveyor mechanisms 22. When it reaches a certain position, the positioning mechanism 21 positions the circuit board 92. Then, the insertion device 70 inserts the transformer 91 onto the circuit board 92, thus completing the insertion operation of the transformer 91. During this process, after the positioning mechanism 21 positions the circuit board 92, the position of the circuit board 92 is fixed, and the insertion device 70 can accurately insert the transformer 91 into the circuit board 92, improving the insertion accuracy and efficiency of the transformer 91.

[0074] In another embodiment of this application, combined with Figure 8 and Figure 9 As shown, the positioning mechanism 21 of the transformer insertion machine 100 includes a second lifting cylinder 211 and a second positioning plate 52 for carrying the circuit board 92. The second lifting cylinder 211 is connected to the frame 10, and the piston rod of the second lifting cylinder 211 is connected to the second positioning plate 52. The second positioning plate 52 is provided with a positioning post 213 for inserting into the positioning hole 521 on the circuit board 92. Specifically, when the circuit board 92 is transported to the second positioning plate 52, the second lifting cylinder 211 drives the second positioning plate 52 to move upward. During the upward movement of the second positioning plate 52, the positioning post 213 of the second positioning plate 52 inserts into the positioning hole 521 of the circuit board 92. As the second positioning plate 52 continues to move upward, it lifts the circuit board 92, thereby separating the circuit board 92 from the belt conveyor mechanism 22. In this way, the circuit board 92 will not continue to move forward due to the influence of the belt conveyor mechanism 22, and the circuit board 92 is in a stationary state. This allows the insertion device 70 to accurately insert the transformer 91 into the circuit board 92, improving the insertion accuracy and efficiency of the transformer 91. In addition, during the lifting of the circuit board 92, the circuit board 92 is limited by the positioning post 213, and the circuit board 92 will not move due to inertia. This allows the circuit board 92 to be accurately positioned on the second positioning plate 52, thereby further improving the insertion accuracy and efficiency of the transformer 91.

[0075] In this embodiment, the positioning mechanism 21 further includes a positioning connecting frame 214 and a positioning mounting frame 215. The positioning mounting frame 215 is mounted on the support platform 11, the second lifting cylinder 211 is mounted on the positioning mounting frame 215, and the second positioning plate 52 is mounted on the positioning connecting frame 214. The positioning connecting frame 214 is connected to the piston of the second lifting cylinder 211, and the positioning mounting frame 215 and the positioning connecting frame 214 are slidably connected by a vertically arranged linear guide slider 24. This arrangement makes the up-and-down movement of the entire second positioning plate 52 more stable and reliable, which is beneficial to improving the positioning accuracy of the circuit board 92.

[0076] In this embodiment, the number of positioning posts 213 can be two, three, or more. The more positioning posts 213 there are, the more accurate the position of the circuit board 92 on the second positioning plate 52 will be. The better the accuracy, the higher the insertion accuracy and efficiency of the subsequent transformer 91. For example, the second positioning plate 52 has two positioning posts 213 along the conveying direction of the belt conveyor mechanism 22. The two positioning posts 213 are respectively inserted into the positioning holes 521 at two opposite corners of the circuit board 92. In this way, the circuit board 92 can neither move nor rotate. The circuit board 92 has good positioning accuracy on the second positioning plate 52, and can also realize the efficient insertion of the subsequent transformer 91.

[0077] In another embodiment of this application, combined with Figure 8 As shown, the conveying device 20 of the provided transformer insertion machine 100 also includes a lead screw 23 and a slider 24; one of the two belt conveyor mechanisms 22 is fixedly connected to the frame 10, and the other is connected to the slider 24; the slider 24 is screwed onto the lead screw 23, and the lead screw 23 is rotatably connected to the frame 10. The rotation of the lead screw 23 drives the slider 24 to move, thereby adjusting the distance between the two belt conveyor mechanisms 22. Specifically, the rotation of the lead screw 23 drives the slider 24 and the belt conveyor mechanism 22 connected to the slider 24 to move along the length of the lead screw 23, thus realizing the adjustment of the distance between the two belt conveyor mechanisms 22. The adjustable distance between the two belt conveyor mechanisms 22 meets the usage requirements of circuit boards 92 of different sizes, improving the versatility of the transformer insertion machine 100. It should be noted that the second positioning plate 52 and the piston rod of the second lifting cylinder 211 are connected by detachable means such as bolts or plugs, so as to facilitate the replacement of the corresponding second positioning plate 52 for positioning and matching according to different sizes of circuit boards 92.

[0078] In this embodiment, fixed seats 27 are provided at both ends of the lead screw 23, and the lead screw 23 can rotate relative to the fixed seats 27. The fixed seats 27 are installed on the support platform 11. The slider 24 is provided with a guide sleeve 29. A guide rod 28 parallel to the lead screw 23 is connected between the two fixed seats 27. The guide sleeve 29 is sleeved on the guide rod 28 and can slide along the guide rod 28, thereby providing guidance for the movement of the slider 24 relative to the lead screw 23, making the movement of the slider 24 more stable and reliable.

[0079] In this embodiment, the number of lead screws 23 can be two, three, or more than four. The more lead screws 23 there are, the more stable and reliable the movement of the belt conveyor mechanism 22 connected to them will be. For example, there are two lead screws 23, which are located at the two ends of the belt conveyor mechanism 22 respectively. The two lead screws 23 are connected by a belt pulley transmission mechanism 25. One of the lead screws 23 has a rotating wheel 26 at its end. When the operator operates the rotating wheel 26 to rotate, it drives the lead screw 23 connected to it to rotate. Since the two lead screws 23 are connected by the belt pulley transmission mechanism 25, the rotation of the lead screw 23 connected to the rotating wheel 26 will drive the other lead screw 23 to rotate at the same time, thereby driving the slider 24 screwed on the two lead screws 23. In this way, the distance between the two belt conveyor mechanisms 22 can be adjusted. This method of adjusting the distance between the two belt conveyor mechanisms 22 by driving the lead screw 23 to rotate through the rotating wheel 26 is simple to operate.

[0080] The working principle of the transformer insertion machine 100 according to the present application embodiment is described below. The circuit board 92 is conveyed to the positioning mechanism 21 for positioning by the belt conveyor mechanism 22. The transformer 91 is automatically fed to the positioning fixture 80 by the vibratory plate 32 and the linear vibrator 33, and then clamped to the shaping device 40 by the picking device 60. At the same time, the picking device 60 clamps the shaped transformer 91 on the shaping device 40 to the positioning device 50. Then, the robot arm 71 drives the third transformer gripper 72 to grab the transformer 91 from the positioning device 50 to the positioning mechanism 21 for insertion. After insertion is completed, the belt conveyor mechanism 22 conveys the circuit board 92 to the next process. This transformer insertion machine 100 completes the automatic feeding, automatic shaping and automatic insertion process of the transformer 91. Furthermore, the width between the two belt conveyor mechanisms 22 is adjustable, making it suitable for various circuit boards 92; and the material handling mechanism can detect excessive pin deformation of the transformer 91 through the first detection element 663, and automatically reject defective incoming materials; in addition, the robotic arm 71 has a high degree of freedom, simple mechanism, and is easy to maintain and switch between different sizes of circuit boards 92, similar to the high degree of universality of electronic component plug-ins.

[0081] Specifically, the vibratory feeder 32 and the linear vibrator 33 automatically arrange the transformers 91 in a preset posture (with the transformers 91 in a pin-down posture) and feed them to the positioning fixture 80. The positioning fixture 80 senses the arrival of the material and sends a material-ready signal to the material-picking device 60, and prevents the subsequent transformers 91 from being pulled out by the pressure plate 83. After receiving the material-ready signal and the completion signal from the shaping device 40, the material-picking device 60 drives the first transformer gripper 63 and the second transformer gripper 64 to simultaneously grab the transformers 91 on the positioning fixture 80 and the shaping device 40 through the linear module 61 and the first lifting cylinder 62. Then, the first transformer gripper 63 is driven to move the transformers 91 on the positioning fixture 80 into the shaping device 40, while the second transformer gripper 64 moves the transformers 91 on the shaping device 40 to the positioning mechanism 21. If the pins of the transformer 91 on the positioning fixture 80 are severely deformed and cannot be inserted into the shaping device 40, the first elastic element 662 connected to the first transformer gripper 63 will be compressed. After the first detection element 663 detects this, it outputs a signal to determine that the incoming material is deformed. The material handling mechanism will then grab the transformer 91 and place it into the first defective product box. After the material handling mechanism completes its operation, it sends a signal to the robot arm 71 indicating that it can handle the material. The robot arm 71 then drives the third transformer gripper 72 to the positioning mechanism 21 to handle the material. The connection structure between the third transformer gripper 72 and the piston rod of the first lifting cylinder 62 is the same as the connection structure and operating principle between the third transformer gripper 72 and the end of the robot arm 71. If the second elastic element 76 is compressed, the second detection element 77 outputs an NG signal. The distance between the two belt conveyor mechanisms 22 can be adjusted by the lead screw 23 to accommodate circuit boards 92 of different sizes. The positioning mechanism 21 is precisely positioned with the second positioning plate 52 by two positioning posts 213. When replacing circuit boards 92 of different sizes, the corresponding second positioning plate 52 must be replaced.

[0082] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
