All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention provides a tray conveying and positioning device of an IGBT bonding machine, which is shown in figures 1-2, and comprises a mounting frame 1 and a DBC tray 3 which moves along the mounting frame 1 through a conveyor belt 2, wherein a positioning mechanism 4 is slidably arranged at the bottom of the mounting frame 1, the positioning mechanism 4 is composed of a screw rod mechanism 41 fixedly arranged on a bottom plate of the mounting frame 1, a telescopic mechanism 42 fixedly arranged on a movable part of the screw rod mechanism 41 and a limiting assembly 43 fixedly arranged on the telescopic mechanism 42, and a notch 5 matched with the limiting assembly 43 is arranged on the side surface of the DBC tray 3.
At first, the telescopic mechanism 42 is in an extending state, a plurality of DBC trays 3 carrying DBC substrates (the DBC substrates are arranged in preset grooves on the DBC trays 3) are driven by a conveying belt to be conveyed forwards, and a limiting component 43 at the end part of the telescopic mechanism 42 just clamps into a notch 5 at the end part of the DBC trays 3, so that the front, back, left and right directions of the trays are limited, the positions of the trays are accurately determined, and after the photoelectric sensors 6 and the correlation sensors sense that the DBC trays 3 are in place and the DBC substrates in the trays exist, the bonding machine performs next bonding action on the DBC substrates below;
after the bonding operation is completed, the screw rod mechanism 41 works to drive the telescopic mechanism 42 and the limiting assembly 43 to move to the next positioning position, the material tray is driven by the conveying belt to move forwards, and the material tray stops after being blocked by the limiting assembly 43, so that the DBC substrate to be bonded in the DBC material tray 3 is positioned below the bonding machine accurately, and at the moment, the next bonding operation can be performed again. The above actions are repeatedly executed until all DBC substrates in the tray are bonded. Then the telescopic mechanism 42 drives the limiting component 43 to retract, and the DBC tray 3 is driven by the conveyor belt 2 to be conveyed to the discharging position.
The limiting assembly 43 is formed by symmetrically and fixedly arranging two limiting vertical rods 432 at the upper end of a transverse plate 431, and the transverse plate 431 is fixedly arranged on the movable part of the screw rod mechanism 41. The limiting vertical rods 432 symmetrically arranged are respectively clamped into the notches 5 formed in the end parts of the DBC material trays 3, limiting to the front, back, left and right directions of the DBC material trays 3 is achieved, and positioning is more stable and rapid.
