Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of circuit board processing equipment, in particular to a printed circuit board device based on field effect transistor embedding. BACKGROUND

[0002] The field effect transistor (FET) is a commonly used semiconductor device for circuit boards to control the output current by input signal, and its core is to realize regulation and control by changing the channel conductivity through the electric field. In order to improve the performance of the circuit board (such as: shortening the conduction path, reducing the parasitic parameter, improving the high frequency performance and integration), some manufacturers will use embedding processing technology to process the field effect transistor. When embedding the field effect transistor, a special printed circuit board device is needed to automatically place the field effect transistor on the circuit board for processing. However, the existing printed circuit board device still has the following shortcomings: Firstly, the automatic feeding efficiency of the existing printed circuit board device is low, which causes the device to spend a long time to complete the placement of the field effect transistor during continuous embedding processing, thereby interfering with the processing efficiency of the device. Secondly, the existing field effect transistor adjustment steps are complicated, which causes the device to spend a long time to complete the size adjustment when placing the field effect transistor at other positions of the circuit board with other sizes, thereby interfering with the transition adjustment efficiency of the workers.

[0005] Furthermore, the mobile material conveying assembly includes a support plate, and a guide slider is fixedly installed at the bottom of the support plate. A first connecting mechanism is fixedly connected to the bottom of the guide slider, and the interior of the first connecting mechanism is threadedly connected to the outer surface of the hand-cranked screw. Meanwhile, a material conveying mechanism is installed on the inner side of the support plate.

[0006] Furthermore, the bottom of the support plate is fixedly connected to the top of the guide slider, and the outer surface of the guide slider is slidably connected to the inner surface of the fixed bracket, and the support plate forms a sliding structure with the fixed bracket through the guide slider.

[0007] Furthermore, the connecting assembly includes a support bracket, and a snap-fit ​​strip is fixedly installed on the left side of the support bracket. The snap-fit ​​strip has through holes evenly spaced inside. A connecting frame is fixedly installed on the right side of the support bracket, and the top of the connecting frame is connected to the bottom of the vibrating table. The outer surface of the snap-fit ​​strip is adapted to engage with the inner surface of the fixed bracket.

[0008] Furthermore, the bottom of the fixing rod is fixedly connected to the top of the bearing bracket, and the top of the fixing rod is fixedly connected to the bottom of the inner conical toothed ring, and the inner conical toothed ring forms a fixed structure with the bearing bracket through the fixing rod.

[0009] Furthermore, the feeding assembly includes a support platform, and the bottom of the support platform is equipped with arc-shaped sliders at equal intervals in a ring, and the top of the support platform is fixedly equipped with a protective shell at equal intervals in a ring. The inside of the protective shell is rotatably connected to a reciprocating screw, and a bevel gear is fixedly installed on the outer surface of the extended end of the reciprocating screw. The top of the protective shell is movably equipped with a material picking mechanism.

[0010] Furthermore, the bottom of the support platform is fixedly connected to the top of the arc-shaped slider, and the bottom of the arc-shaped slider is slidably connected to the top of the support bracket, and the support platform and the support bracket form a sliding structure through the arc-shaped slider.

[0011] Furthermore, the material handling mechanism includes a T-shaped plate, and an L-shaped connecting bracket is fixedly installed at one end of the T-shaped plate. A lifting cylinder is installed through the other end of the L-shaped connecting bracket, and a hollow connecting plate is fixedly connected to the extended end of the lifting cylinder. At the same time, a material handling nozzle is fixedly installed at the bottom of the hollow connecting plate.

[0012] Furthermore, the material handling mechanism also includes a counterweight block, which is fixedly installed on the top of the T-shaped plate, and a connecting block is fixedly connected to the bottom of the T-shaped plate.

[0014] This invention provides a printed circuit board device based on embedded field-effect transistors, which has the following advantages: 1. This invention, through the design of an inner conical toothed ring and a bevel gear, enables the drive motor to rotate the support platform. The meshing connection between the inner surface of the inner conical toothed ring and the outer surface of the bevel gear allows the support platform to drive the reciprocating screw to rotate synchronously within the protective housing. This allows the four sets of material-picking mechanisms to move sequentially, retracting and extending. When a material-picking mechanism moves directly above the vibrating platform, it is in a retracted state; when it moves directly above the fixed bracket, it is in a fully extended state. This allows the four sets of material-picking mechanisms to sequentially pick up and feed materials, greatly improving the automatic feeding efficiency and operational continuity of the printed circuit board device (i.e., while one set of material-picking mechanisms is placing the field-effect transistor, the opposite set is simultaneously picking up materials). This avoids the situation where the device needs to spend a long time each time placing the field-effect transistor during continuous embedding processing, thus preventing interference with the device's processing efficiency.

[0015] 2. This invention, through the guide slider and the first connecting mechanism, enables the operator to rotate the hand-cranked screw inside the fixed plate, thereby allowing the carrier plate to move laterally along the inner surface of the fixed bracket. This achieves the purpose of quickly adjusting the distance between the mobile and fixed material conveying components. Furthermore, the snap-fit ​​strip and through holes facilitate quick adjustment of the distance between the carrier bracket and the fixed bracket, providing convenience for the operator to adjust the material placement position of the material handling mechanism. This avoids the situation where the device needs to spend a long time to complete the size adjustment work when placing field-effect transistors in other positions on circuit boards of other sizes, which would interfere with the operator's efficiency in changing locations.

[0018] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0019] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, a printed circuit board device based on embedded field-effect transistors includes a fixed bracket 1, a connecting assembly 6, and a feeding assembly 10. The connecting assembly 6 is movably mounted on the right side of the fixed bracket 1. The connecting assembly 6 includes a support bracket 61, and a snap-fit ​​strip 62 is fixedly installed on the left side of the support bracket 61. The bottom of the fixing rod 7 is fixedly connected to the top of the support bracket 61, and the top of the fixing rod 7 is fixedly connected to the bottom of the inner conical toothed ring 8. The inner conical toothed ring 8 and the support bracket 61 form a fixed structure through the fixing rod 7. By setting the inner conical toothed ring 8 and the support bracket 61 into a fixed structure, the inner conical toothed ring 8 will not tilt when the auxiliary drive bevel gear 105 rotates. The snap-fit ​​strip 62 has equidistant openings inside. The system includes a through hole 63, and a connecting frame 64 is fixedly installed on the right side of the support bracket 61. The top of the connecting frame 64 is connected to the bottom of the vibrating table 11. The outer surface of the snap-fit ​​strip 62 is fitted and engaged with the inner surface of the fixed bracket 1. The top of the connecting assembly 6 is equipped with fixed rods 7 at equal intervals in a ring, and an inner conical toothed ring 8 is fixedly installed on the top of the fixed rods 7. A drive motor 9 is installed at the bottom of the connecting assembly 6. The feeding assembly 10 is slidably connected to the top of the connecting assembly 6. The feeding assembly 10 includes a support table 101, and arc-shaped sliders 102 are installed at equal intervals in a ring at the bottom of the support table 101. The bottom of the support table 101 is fixedly connected to the top of the arc-shaped sliders 102, and the bottom of the arc-shaped sliders 102 is fixedly connected to the support bracket 11. The top of the support frame 61 is slidably connected, and the support platform 101 forms a sliding structure with the support bracket 61 through the arc-shaped slider 102. The sliding structure of the support platform 101 and the support bracket 61 makes the rotation of the support platform 101 along the top of the support bracket 61 smoother and more stable. A protective shell 103 is fixedly installed at equal intervals in a ring shape on the top of the support platform 101. A reciprocating screw 104 is rotatably connected inside the protective shell 103, and a bevel gear 105 is fixedly installed on the outer surface of the extended end of the reciprocating screw 104. A material-picking mechanism 106 is movably installed on the top of the protective shell 103. The material-picking mechanism 106 includes a T-shaped plate 1061, and an L-shaped connecting rod is fixedly installed at the end of the T-shaped plate 1061. The L-shaped connecting bracket 1062 is connected to a lifting cylinder 1063, which is installed through the other end of the L-shaped connecting bracket 1062. A hollow connecting plate 1064 is fixedly connected to the extension end of the lifting cylinder 1063. A material-collecting suction nozzle 1065 is fixedly installed at the bottom of the hollow connecting plate 1064. The material-collecting mechanism 106 also includes a counterweight 1066, which is fixedly installed on the top of the T-shaped plate 1061. A connecting block 1067 is fixedly connected to the bottom of the T-shaped plate 1061, and a second connecting mechanism 1068 is installed at the bottom of the connecting block 1067. The top of the connecting block 1067 is fixedly connected to the bottom of the T-shaped plate 1061, and the bottom of the connecting block 1067 is fixedly connected to the top of the second connecting mechanism 1068.Furthermore, the T-shaped plate 1061 forms a fixed structure with the second connecting mechanism 1068 via the connecting block 1067. This fixed structure of the T-shaped plate 1061 and the second connecting mechanism 1068 ensures a more secure connection when the second connecting mechanism 1068 moves the T-shaped plate 1061 along the inner surface of the protective housing 103. Simultaneously, rectangular sliders 1069 are symmetrically fixedly installed on both sides of the second connecting mechanism 1068, with their outer surfaces slidably connected to the inner surface of the protective housing 103. A vibrating material table 11 is installed on the top right side of the connecting assembly 6.

[0020] like Figures 1-3 As shown, a fixed material conveying assembly 2 is installed on the inner side of the fixed bracket 1, and a fixed plate 3 is symmetrically fixedly installed on the bottom of the fixed bracket 1. A hand-cranked screw 4 is rotatably connected inside the fixed plate 3, and a movable material conveying assembly 5 is movably installed on the outer surface of the hand-cranked screw 4. The movable material conveying assembly 5 includes a bearing plate 51, and a guide slider 52 is fixedly installed on the bottom of the bearing plate 51. The bottom of the bearing plate 51 is fixedly connected to the top of the guide slider 52, and the outer surface of the guide slider 52 is slidably connected to the inner surface of the fixed bracket 1. The bearing plate 51 and the fixed bracket 1 form a sliding structure through the guide slider 52. By setting the bearing plate 51 and the fixed bracket 1 into a sliding structure, the bearing plate 51 moves more smoothly and stably when it moves laterally along the top of the fixed bracket 1. A first connecting mechanism 53 is fixedly connected to the bottom of the guide slider 52, and the inside of the first connecting mechanism 53 is threadedly connected to the outer surface of the hand-cranked screw 4. At the same time, a material conveying mechanism 54 is installed on the inner side of the bearing plate 51, and a connecting assembly 6 is movably installed on the right side of the fixed bracket 1.

[0021] In summary, combining Figures 1-6 As shown, the working principle of the printed circuit board device based on embedded field-effect transistors is as follows: First, the operator grasps the hand-cranked screw 4 and drives it to rotate inside the fixed plate 3. At this time, through the connection of the first connecting mechanism 53 and the sliding of the guide slider 52, the bearing plate 51 moves along the inner surface of the fixed bracket 1, thereby achieving the purpose of quickly adjusting the distance between the movable feeding assembly 5 and the fixed feeding assembly 2. When the distance between the movable feeding assembly 5 and the fixed feeding assembly 2 is the same as the length of the circuit board to be processed, the hand-cranked screw 4 is stopped. Then, the positioning bolts are pulled out from the inside of the fixed bracket 1 in sequence. Next, the bearing bracket 61 is grasped and the snap-fit ​​strip 62 is pulled out or pushed in along the inner surface of the fixed bracket 1, thereby achieving the purpose of quickly adjusting the feeding position of the picking mechanism 106. After the feeding position of the picking mechanism 106 is adjusted, the positioning bolts are inserted into the inside of the fixed bracket 1 in sequence. At this time, the snap-fit ​​strip 62 is fixed through the cooperation of the through hole 63. After the device is adjusted, the operator places the field-effect transistor to be embedded inside the vibrating table 11. Then, the controller opens the fixed conveying assembly 2 and the conveying mechanism 54, ensuring their synchronous operation. When the conveying mechanism 54 and the fixed conveying assembly 2 start running, the circuit board to be processed is transported. Then, the infrared positioner in the fixed bracket 1 positions the movement of the circuit board. When the infrared positioner senses the circuit board, the conveying mechanism 54 and the fixed conveying assembly 2 close. Then, the drive motor 9 starts running. At this time, the sliding of the arc-shaped slider 102 causes the support table 101 to rotate stably along the top of the support bracket 61. At this time, the outer surface of the bevel gear 105 meshes with the inner surface of the inner conical gear ring 8, so that when the support table 101 rotates, the bevel gear 105 drives the reciprocating screw 104 in the protective shell. The body 103 rotates synchronously inside. At this time, through the connection of the second connecting mechanism 1068 and the guide sliding of the rectangular slider 1069, the connecting block 1067 drives the T-shaped plate 1061 to extend and move along the top of the protective housing 103. When the picking nozzle 1065 rotates to the top of the circuit board, the second connecting mechanism 1068 moves to the outer end of the protective housing 103, so that the T-shaped plate 1061 is at the maximum extension distance. Then, the lifting cylinder 1063 at the end of the L-shaped connecting bracket 1062 starts to operate, so that the hollow connecting plate 1064 drives the picking nozzle 1065 to descend and accurately place the picked field-effect transistor on the reserved position of the circuit board. At the same time, when the picking mechanism 106 accurately places the field-effect transistor, the opposite picking mechanism 106 automatically picks up the field-effect transistor in the vibrating table 11 for subsequent circuit board loading. Finally, after the field-effect transistors are placed, the lifting cylinder 1063 drives the material suction nozzle 1065 to rise. Then, the material conveying mechanism 54 and the fixed material conveying assembly 2 start to operate and transport the circuit board with the field-effect transistors to the subsequent processing equipment for subsequent film lamination processing.
