[0002] At present, in the production process of semiconductor chips and other products, trays are the "material trays" that carry workpieces on the production line. They are widely used in the packaging and transportation of electronic components. They can protect components from damage during transportation. Their specifications are generally 2 inches, 3 inches, and 4 inches.

[0003] After loading products in trays, they usually need to be stacked together for easy transportation, transfer and storage. In the prior art, the stacked trays are usually transferred to the next process by manual labor and handling tools, or conventional conveyor lines are used for transfer, which cannot adapt to the transfer of trays of multiple specifications and cannot be lifted to cooperate with other processes to achieve flow production. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a variable-pitch loading and lifting mechanism, including a support seat, and a horizontal variable-pitch flow channel and a variable-pitch lifting assembly installed on the support seat, wherein the discharge port of the horizontal variable-pitch flow channel is connected to the feed port of the variable-pitch lifting assembly.

[0005] Wherein: the horizontal variable-pitch flow channel comprises a horizontal guide rail arranged on the upper surface of the support seat, and outer frames symmetrically arranged and located on both sides above the horizontal guide rail; a 4-inch flow channel, a 3-inch flow channel and a 2-inch flow channel with successively smaller spacings are arranged between the outer frames on both sides to correspond to the horizontal conveyance of a 4-inch tray, a 3-inch tray and a 2-inch tray respectively;

[0006] The horizontal variable-pitch flow channel further includes a linear module arranged on the upper surface of the support seat, and a push plate driven by the linear module and moving along the horizontal guide rail, wherein the push plate is correspondingly located between the outer frames on both sides.

[0007] Furthermore: the support seat is also provided with an in-position limiter corresponding to the push plate.

[0008] Wherein: the variable pitch lifting assembly comprises a bracket arranged on the upper surface of the support seat, a stepper motor 1 installed on the bracket, a bidirectional screw rod arranged horizontally and driven by the stepper motor 1 through a transmission assembly 1, and a horizontal limit plate arranged symmetrically and driven by the bidirectional screw rod to move relative or reversely, and the horizontal limit plate moves relative or reversely to correspond to the size of the tray delivered by the horizontal variable pitch flow channel;

[0009] The variable pitch lifting assembly also includes a stepper motor 2 installed on the bracket, a one-way screw vertically arranged and driven by the stepper motor 2 through a transmission assembly 2, a lifting block threadably connected to the one-way screw, and a lifting plate installed on the lifting block, wherein the lifting plate is located correspondingly below the tray for step-by-step lifting of trays of different sizes.

[0010] Furthermore: the variable distance lifting assembly also includes a guide column 1 for guiding the horizontal limit plates on both sides when they move relative to or in the opposite direction.

[0011] Compared with the prior art, the utility model is different from the single tray feeding mechanism on the market. It can make use of the height difference and width difference of the workpiece to make a flow channel suitable for 2, 3, and 4-inch trays, and use a servo module to push the product in the flow channel to the jacking feeding assembly, and then realize the positioning of the product through the centering movement of the bidirectional screw rod. Finally, the jacking mechanism is used to accurately control the tray to be lifted to the same position to facilitate material retrieval, thereby solving the feeding problem of trays of various specifications, reducing equipment cost and space, and having the advantages of stable and reliable operation, stable feeding and high compatibility.
