The structure of this plug-in machine is often very complicated, and its maintenance cost is high, which causes great financial pressure on the company. Moreover, this plug-in machine is a special plug-in machine. Its scope of application is relatively narrow, and there is no special plug-in machine for LEDs at present. In addition, these plug-in machines are often difficult to control the insertion force of special-shaped electronic components, resulting in a reduction in yield and waste. At present, there is no LED plug-in device with low maintenance cost, wide application range, accurate automatic plugging and high yield rate in the market.

The present invention aims to solve the above-mentioned shortcomings of the prior art, and provides an LED plug-in device with low maintenance cost, wide application range, precise automatic insertion and high yield rate, so as to meet production requirements.

The technical solution adopted by the present invention to solve its technical problems: this LED plug-in device includes a workbench, a base plate is provided on the workbench, support plates are provided at both ends of the base plate, and slide rails are arranged horizontally between the two support plates. One cylinder, the slide rail is provided with a slide plate, the piston rod of the first cylinder is connected with the slide plate, the slide plate is provided with the second cylinder, the piston rod of the second cylinder is provided with a mounting plate, and the mounting plate is provided with a pick-up and clamping mechanism, The workbench below the pick-up and clamping mechanism is provided with a feed mechanism with X and Y direction feed functions. A controller is arranged under the workbench, and the first cylinder, the second cylinder, the picking and clamping mechanism, and the feeding mechanism are all connected with the controller. In this way, the controller issues an instruction, the pick-up and clamping mechanism clamps the light-emitting diode to pick up, the piston rod of the second cylinder shrinks to lift the pick-up and clamping mechanism, and then starts the first cylinder and the feed mechanism to adjust the appropriate position, the second cylinder The piston rod is stretched and inserted into the light-emitting diode to complete a plug-in process.

Further, the pick-up and clamping mechanism includes a fixed rod arranged on the mounting plate. A clamp is connected to the shaft of the fixed rod. Elastic connecting rods are arranged on the inner sides of the two legs of the clamp. The two elastic connecting rods are connected by cylindrical pins. An electromagnet is provided, and an armature is arranged in the electromagnet, and a cylindrical pin is fixed on the armature. The elastic connecting rod is a spring-type connecting rod. In this way, when the LED needs to be picked up and clamped, the electromagnet is energized, and the armature moves down in the electromagnet, driving the cylindrical pin, driving the elastic connecting rod to force the clamp to perform clamping action, and the elastic connecting rod can play a buffering role. Avoid damaging the LED when clamping. A third cylinder is arranged on the slide plate, and the second cylinder is arranged on the piston rod of the third cylinder. This can prolong the distance that the pick-up and clamping mechanism moves up and down, which is convenient for operation. The skateboard is an L-shaped skateboard, the four corners of the back of the skateboard are respectively provided with sliders, and the sliders are sheathed on the slide rails.

The beneficial effects of the present invention are: the structure of the present invention is reasonable and compact, and through the joint action of clamps, elastic connecting rods, cylindrical pins, armatures, electromagnets, feed mechanisms and cylinders, the precise pick-up and insertion of light-emitting diodes can be realized.
