technical field

The invention belongs to the technical field of LED patch processing, and in particular relates to an LED patch machine.

Background technique

As a very effective new light source, LED has the advantages of high brightness, low power consumption, long life, stable performance, and easy matching with integrated circuits. As a new green light source for energy saving and environmental protection, it is currently widely used in landscape lights, background screens, street lights, Indoor lighting and other occasions. With the cost reduction and wide application of SMD LEDs, various manufacturers are developing SMD LED fluorescent lamps. The length of traditional fluorescent lamps is about 1.2m. Since the chip length of a general-purpose placement machine is generally about 0.4m, it cannot meet the needs of patch-type fluorescent lamps. At the same time, the general-purpose placement machine is expensive, which is not conducive to reducing costs. At the same time, the general-purpose placement machine has a complex structure and is difficult to manufacture. big.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

In the embodiment of the present invention, the X-axis is mainly composed of an optical axis and a lead screw, so that the beam is light in weight. Compared with the synchronous belt drive, the motor inertia is small with this driving method; the two optical axes and the two synchronous belts on the Y-axis The drives are distributed on the left and right sides of the machine, and the middle is driven by a motor, so that the drive of the beam is not a side drive but a symmetrical drive, which ensures the deflection accuracy of the beam, symmetrical drive, good reliability and long life. At the same time, the optical axis replaces the guide rail. The guide rail seat reduces cost and manufacturing difficulty; the frame and table panel in the embodiment of the present invention are divided into two bodies, reducing manufacturing difficulty and cost, while the adjustment mechanism is simple and easy to operate.

In order to set forth the present invention better, illustrate by specific embodiment, as follows:

As shown in FIGS. 1 to 4 , an LED placement machine provided by an embodiment of the present invention includes a frame 1 , an X/Y motion platform 2 , a placement head 3 , a board feeding mechanism 4 and a top plate mechanism 5 .

Frame 1 adopts welded structure, which is welded by 12 square steels, and the reference plate is placed on it to form the support foundation of the X/Y motion platform.

The X/Y motion platform is composed of a Y motion mechanism and an X motion mechanism. The X motion mechanism is set on the Y motion mechanism and slides along the Y direction. The Y motion mechanism is supported by the frame 1 through two Y optical axes 11, and the driving part It is arranged between the ends of the same side of the two Y optical axes 11 (the rear middle of the two Y optical axes 11), forming a symmetrical structure. The driving part includes a Y servo motor 12, two couplings 13 and two transmission shafts 14, The Y servo motor 12 is connected to the two transmission shafts 14 through two couplings 13, and the belt 20 is driven by the two transmission shafts 14 to drive the X motion mechanism to slide along the Y direction synchronously.

The X servo motor 16 directly drives the ball screw 17 between the two X-ray axes 19 to make the placement head 3 move left and right along the X-ray axis 19 .

The mounting head 3 is set on the X motion mechanism and slides along the X direction. The mounting head 3 is mainly composed of two parts: the lifting part (δ axis) 6, the mounting part (Z axis) 7, and the lifting part 6 driving the mounting part 7 Up and down movement, the lifting part is composed of substrate, linear guide rail, servo motor, synchronous belt, synchronous pulley and adjustment device, the guide rail slider is connected with the mounting part, the synchronous belt is connected with the synchronous belt bracket, and synchronized when the servo motor rotates The wheel drives the synchronous belt and the synchronous belt bracket to drive the placement part to move up and down; the placement part is driven by the Z servo motor 8 to drive the cam disc 9 to rotate counterclockwise. The motion mode pushes the spindle to move in turn to complete the placement and retrieving.
