[0002] LED digital tubes are composed of multiple light-emitting diodes packaged together to form an "8"-shaped device. The leads have been connected internally, and only their individual strokes and common electrodes need to be led out. The digital tube is actually composed of seven light-emitting tubes forming an 8-shaped shape, plus the decimal point, which is 8. These segments are represented by letters a, b, c, d, e, f, g, dp, and a pressing machine is needed in the production process of LED digital tubes.

[0003] The existing automatic pressing and splicing machine for LED digital tube production places a PIN pin on the PCB board of the LED digital tube, places it on a jig and applies pressure to the PIN pin through a pressing plate, thereby fixing it on the PCB. In the unloading process of the above method, since the PCB board fits tightly with the jig after being pressed, it is not convenient for the staff to take it out, which not only affects the working efficiency of the device, but also leads to poor use effect of the device. Therefore, an automatic pressing and splicing machine for LED digital tube production is urgently needed to solve the above problems. Utility Model Content

[0024] The screw rod 3 is rotatably installed in the slide slot 10, the guide rod 11 is welded in the slide slot 10, the output shaft of the motor 12 is fixedly connected to one end of the screw rod 3, the motor 12 drives the screw rod 3 to rotate, and the guide rod 11 limits and guides the movement of the screw block.

[0025] The moving block 13 is rotated on the screw rod 3 through a thread, and the guide rod 11 passes through the moving block 13 . When the screw rod 3 rotates, the moving block 13 drives the jig 9 to move under the action of the screw block and the guide rod 11 .

[0026] The flip chamber 14 is formed on the moving block 13, the fixed part of the electric push rod 16 is hinged to the flip chamber 14, the output end of the electric push rod 16 is hinged to the back wall of the flip plate 15, one end of the flip plate 15 is rotatably connected to the flip chamber 14, and the jig 9 is fixed to the flip plate 15 by screws. When the PCB board needs to be taken out of the jig 9 after pressing, the electric push rod 16 moves to push the flip plate 15 to rotate in the flip chamber 14, and then flips the jig 9, so that the PCB board can be automatically separated from the jig 9 by its own gravity, which is convenient for the staff to unload and improve the working efficiency and use effect of the device.
