Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1 , Figure 2 and Figure 3The digital tube riveting assembly equipment includes a base platform 1, on which are provided: a first conveyor belt 2, a vibrating feeding track 3, a flipping mechanism 4, a transfer mechanism 5, a second conveyor belt 6, a hot riveting mechanism 7, a first transfer station 8, and a second transfer station 9.

[0035] like Figure 2 , Figure 4 and Figure 5 As shown, the first conveyor belt 2 is used to transport PCB boards to the assembly station. The first conveyor belt 2 includes two parallel synchronous belts 21. The two synchronous belts 21 jointly carry the PCB boards and move forward synchronously. One of the synchronous belts 21 is connected to a lead screw assembly 22. When the lead screw of the lead screw assembly 22 rotates, it drives the synchronous belt 21 to move perpendicular to the conveying direction, thereby adjusting the spacing between the two synchronous belts 21 to accommodate the width of the PCB board. Retractable stop blocks 23 are provided on both sides of the assembly station of the first conveyor belt 2. The stop blocks 23 are driven by cylinders 24 and extend and retract perpendicular to the conveying direction. The stop blocks 23 are used to prevent the PCB board from continuing to move along the first conveyor belt 2 in the conveying direction.

[0036] like Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the input end of the vibrating feeding track 3 is connected to a vibrating plate 31, which is used to transport digital tube housings to the vibrating feeding track 3. The digital tube housings are plastic housings, and multiple heat-melting columns are provided on one side of the plastic housings. The conveying direction of the vibrating feeding track 3 is perpendicular to the first conveyor belt 2. The output end of the vibrating feeding track 3 is connected to a first transfer station 8, which transports the digital tube housings to the first transfer station 8. The heat-melting columns of the digital tube housings on the first transfer station 8 face upwards.

[0037] A flipping mechanism 4 is provided on one side of the first transfer station 8, and a second transfer station 9 is located on the side of the flipping mechanism 4 away from the first transfer station 8. The flipping mechanism 4 flips the digital tube housing on the first transfer station 8 by 180° and then transfers it to the second transfer station 9. At this time, the heat-melting column of the digital tube housing on the second transfer station 9 faces downwards. Specifically, the flipping mechanism 4 includes a rotation drive unit 41 and a clamping unit 42. The clamping unit 42 is used to clamp and fix the digital tube housing, and the rotation drive unit 4 drives the clamping unit 42 to rotate 180°. Preferably, the rotation drive unit 4 is a rotary motor, and the clamping unit 42 is a conventional clamping cylinder or mechanical clamping mechanism.

[0038] The second transfer station 9 is a light-transmitting platform. Preferably, the light-transmitting platform is made of transparent flat glass. A first camera and a second camera are respectively installed above and below the light-transmitting platform to collect images of the upper and lower surfaces of the digital tube housing located on the light-transmitting platform. The images of the upper and lower surfaces are collected for viewing angle positioning, which can be achieved using conventional visual positioning technology.

[0039] like Figure 1 and Figure 6 As shown, the transfer mechanism 5 is used to transfer the digital tube housing from the second transfer station 9 to the PCB board at the assembly station for positioning and assembly. The transfer mechanism 5 employs a multi-axis robot, whose end effector 51 is equipped with a vacuum suction cup 52 for picking up the digital tube housing. During operation, the multi-axis robot of the transfer mechanism 5 moves to directly above the second transfer station 9 according to system instructions, and then controls the end effector 51 to descend, so that the vacuum suction cup 52 contacts the upper surface of the digital tube housing and forms a negative pressure, reliably picking it up. Next, the multi-axis robot lifts and moves to directly above the PCB board that has been precisely positioned at the end of the first conveyor belt 2. By controlling the movement trajectory of the multi-axis robot, the digital tube housing is accurately placed on the predetermined assembly position on the PCB board, that is, the heat-sealing post of the digital tube housing mates with the mounting hole of the PCB board. Subsequently, the vacuum suction cup 52 breaks the vacuum, releasing the digital tube housing, completing one assembly operation.

[0040] like Figure 2 and Figure 4 As shown, the second conveyor belt 6 extends along the direction of the first conveyor belt 2 and is used to transport the assembled workpiece to the hot riveting station. Specifically, the second conveyor belt 6 includes two parallel conveyor rails 61 and a synchronous drive mechanism 62. The synchronous drive mechanism 62 is used to synchronously adjust the distance between the two conveyor rails 61, and the hot riveting station is located between the two conveyor rails 61. The synchronous drive mechanism 62 adopts a conventional lead screw drive module, and its specific structure will not be described in detail.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, the hot riveting mechanism 7 includes a limiting platform 71 located above the hot riveting station and a lifting hot pressing platform 72 located below. The lifting hot pressing platform 72 can move upward and cooperate with the limiting platform 71 to complete the hot riveting operation. Specifically, when the lifting hot pressing platform 72 moves upward, it lifts the workpiece located on the conveyor guide rail 61 of the second conveyor belt 6 and presses it against the limiting platform 71 to complete the hot riveting. The hot-melt column of the digital tube housing is hot-riveted to the mounting hole of the PCB board.

[0042] A lifting stop plate 73 driven by a lifting cylinder 74 is provided on the limiting platform 71. When the lifting stop plate 73 descends, it limits the workpiece located at the hot riveting station to prevent it from continuing to move along the second conveyor belt 6.

[0043] like Figure 2 As shown, an inclined slide rail 63 is provided at the end of the second conveyor belt 6 to guide the hot-riveted workpiece to the subsequent station. A detection sensor 64 is provided at the end of the inclined slide rail 63 to detect the workpiece at the end.

[0044] This invention utilizes automated collaborative operations to precisely assemble and heat-rivet the digital tube housing to the PCB board. A vibratory feeder and vibratory feeding track automatically organize and transport the digital tube housing. A flipping mechanism rotates the housing 180 degrees, aligning its heat-melting column in the correct direction, and a vision system performs posture calibration. A multi-axis transfer robot, based on positioning data from the vision system, precisely grasps the housing and transfers it above the PCB board, which has been conveyed and positioned by the first conveyor belt, completing the alignment and assembly. The assembled semi-finished product is then fed into the heat-riveting mechanism by a second conveyor belt. At this point, a lifting hot-pressing platform rises, heating and melting the heat-melting column of the digital tube housing, while an upper limiting platform provides a reaction force to ensure a firm and flat riveting. The completed product is automatically output via an inclined slide rail. The entire process is continuous, automated, and highly efficient, significantly improving production efficiency and product quality consistency.

[0045] The specific embodiments described herein are merely illustrative examples of the spirit of this invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this invention or exceeding the scope defined by the appended claims.
