Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0071] During implementation, the spiral feeding vibrating screen conveys the digital tube base H to the base feeding conveyor track. The continuous conveying of the digital tube bases causes the front digital tube base H to move along the base feeding conveyor track. Side limiting plates on both sides of the feeding conveyor track can limit movement at the top of the track, preventing the digital tube base H from being squeezed out. The first robotic arm, driven by the first horizontal moving mechanism, moves back and forth along the feeding conveyor track to the assembly base at the corresponding station, and moves up and down under the drive of the first vertical moving mechanism.

Then, the two robotic arm's insertion claws move outward under the action of the first pneumatic finger-type cylinder, pressing against the inner cavity of the digital tube base. Under the action of the vertical and horizontal moving mechanisms, it rises and moves outward, delivering the digital tube base to the next station.

[0073] In implementation, a glue dispensing hole is provided through the glue applicator 21, which can be connected to an external glue supply device. The external glue supply device is not part of the present invention, so it is omitted. The glue applicator moving mechanism is inclined, and its inclination direction allows the glue applicator to apply glue to the digital tube base H on the corresponding workstation assembly base.

One end of the third lateral moving mechanism 2801 extends out of the second lateral moving mechanism 25 and is arranged along the width of the LED feeding conveyor track 23. One end of the fourth guide plate 2802 away from the third lateral moving mechanism 2801 is arranged downwards as a third vertical moving mechanism 2803. A fifth guide plate 2804 is arranged at the bottom of the third vertical moving mechanism 2803 towards the LED feeding conveyor track 23. A third pneumatic finger-type cylinder 30 is arranged at the bottom of the fifth guide plate 2804.

The third lateral moving mechanism 2801 and the third vertical moving mechanism 2803 have the same structure as the first vertical moving mechanism 11.

[0078] Combined with appendix Figure 26-27 The third pneumatic finger-type cylinder 30 is located on one side of the LED feeding conveyor track 23, and the third pneumatic fingers 3001 are respectively arranged on both sides along the width direction of the LED feeding conveyor track 23. The sorting plate 31 includes a mounting block 3101 disposed on the third pneumatic fingers 3001.

[0079] During implementation, the digital tube LED component I is conveyed on the LED feeding conveyor track. The gap between the two sides of the feeding conveyor belt and the conveyor side plate and the width of the feeding conveyor belt is smaller than the gap between the pins on both sides of the digital tube LED component. When placing the LED component I, the pins on both sides can be placed within the above-mentioned gap, which facilitates the conveying of the digital tube LED component. At the same time, the height difference between the top of the feeding conveyor belt and the top of the conveyor side plate is smaller than the thickness of the digital tube LED component. That is, the digital tube LED component protrudes from the LED feeding conveyor track, so that the digital tube LED component 7 protrudes from the top of the conveyor side plate, which is convenient for the robot to clamp.

[0080] The second lateral moving mechanism has the same structure as the first lateral moving mechanism. The second lateral moving mechanism drives the second vertical moving mechanism and the second robotic arm mounted on it to move along the conveying direction of the digital tube LED assembly. The second vertical moving mechanism drives a rotating rod to rotate via a drive motor, which in turn drives a third sliding plate to move up and down along a third guide rail during rotation, thus adjusting the height of the second robotic arm. The second robotic arm moves inward relative to the second pneumatic finger-type cylinder to clamp the digital tube LED assembly. Then, through the cooperation of the second lateral moving mechanism and the second vertical moving mechanism, the digital tube LED assembly is... The D component moves to the upper part of the digital tube base at the corresponding workstation. On the other hand, during assembly, the feeding and sorting mechanism adjusts its position under the drive of the third and fourth lateral moving mechanisms and moves to the lower part of the digital tube LED component. At the same time, the positioning plate moves inward relative to each other through the third pneumatic finger-type cylinder, so that each pin on the digital tube LED component is located in the sorting groove in the sorting teeth, ensuring the neatness of the pins. Driven by the second vertical moving mechanism, it moves closer to the digital tube base. At the same time, the robot moves closer to the digital tube base under the drive of the first vertical moving mechanism, so that the digital tube LED component 7 docks with the digital tube base.

One end of the bottom of the pressing plate 3409 is provided with a flat pressing groove 3410, and the other end is provided with an inclined pressing surface 3411 corresponding to the inclined surface of the digital tube base.

[0082] During implementation, the third push cylinder moves the push rod and the pressing head downwards, pressing the flat pressing groove onto the digital tube assembly to press the digital tube assembly for the first time. Then, the third push cylinder moves the pressing head upwards, while the fourth push cylinder moves the pressing plate so that the inclined pressing surface is above the digital tube assembly.

[0084] During implementation, the fifth vertical moving mechanism drives the first test connecting plate and positioning plate to move downwards and abut against the top of the digital tube assembly to fix it. The sixth vertical moving mechanism drives the second test connecting plate and test plate to move upwards, so that the conical contact groove of the test probe aligns with the pins extending from the bottom of the digital tube assembly.
