Description

Technical Field

[0001] This utility model relates to the field of automated production equipment technology, specifically to a disk buffer mechanism for temporary storage and circulation of disks in automated production lines. Background Technology

[0002] In automated production lines, trays serve as the carriers and transfer vessels for products (especially small parts or housings), and need to circulate efficiently between workstations. Due to differences in the processing rhythm of different workstations, the transfer speed of the trays often does not match the processing speed of the workstations. Therefore, a buffer mechanism is needed to temporarily store and dynamically schedule the trays in order to optimize the production line process and improve overall production efficiency.

[0003] Existing pallet buffer mechanisms have the following shortcomings: First, they occupy a large space, making it difficult to adapt to the layout requirements of compact production lines; second, the pallet replacement and transfer process is cumbersome, and the cooperation between the AGV and the buffer components is prone to interference, resulting in low transfer efficiency; third, the positioning accuracy is insufficient, and the pallet is prone to deviation during the receiving, lifting and moving process, affecting the stability of subsequent processes.

[0004] Therefore, developing a compact, optimized, and precisely positioned pallet buffer mechanism that enables efficient cooperation between AGVs and buffer components has become the key to solving the pallet transfer problem in automated production lines. Utility Model Content

[0005] This utility model aims to solve the problems of large space occupation, cumbersome process of changing the pallet, easy interference between AGV and buffer components, insufficient positioning accuracy and low efficiency of existing pallet buffer mechanisms.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a disk buffer mechanism, comprising: AGV cart assembly: includes at least two AGV carts, each AGV cart is equipped with four positioning rods for picking up and placing trays (the positioning rods are adapted to the bottom of the trays to achieve stable support of the trays). Lifting Module: Includes a left product lifting module and a right product lifting module, both with identical structures; each lifting module includes a rack and pinion module, two parallel linear guide rails, a base plate, and positioning pins; the base plate is fixed to the slider of the rack and pinion module, and the base plate has a slot for the AGV trolley to enter and exit; the positioning pins are vertically fixed to the base plate and are adapted to the pin holes at the bottom of the tray for precise positioning of the tray; Cylinder moving assembly: includes two sets of symmetrically arranged side cylinder assemblies and one set of lower cylinder assemblies; the lower cylinder assembly is located at the bottom of the buffer mechanism and is used to lift or lower to reserve space for the AGV trolley to enter and exit; each set of side cylinder assemblies includes a lower lifting cylinder (used to lift the side assembly as a whole), a middle rodless cylinder (arranged in the horizontal direction and used to drive the pallet to move horizontally), and a standard cylinder fixed on the rodless cylinder slider (used to grip the pallet). Carrier positions: including lower shell product carrier positions and upper shell product carrier positions, which are used to temporarily place lower shell product carriers and upper shell product carriers respectively, and are adapted to the operating range of the lifting module and cylinder moving assembly.

[0007] This invention achieves efficient buffering and transfer of the pallet through the coordinated action of the AGV trolley component, the lifting module, and the cylinder moving component. The specific working principle is as follows: Carrier tray reception (taking the left product lifting module receiving the fully loaded lower shell carrier tray of AGV trolley 1 as an example): The AGV trolley 1 carries a tray full of products in the lower shell through its four positioning rods, and after picking up the tray through lifting action, it moves to the product buffer component waiting area. The lower cylinder assembly rises to reserve space for the AGV trolley 1 to enter the buffer assembly; The rack and pinion module of the left product lifting module drives the base plate to descend along the linear guide rail, waiting to receive the tray; The AGV trolley 1 moves to the left to the slot of the bottom plate of the left lifting module, so that the bottom plate is directly below the carrier plate; The rack and pinion module of the left product lifting module drives the base plate to rise. The positioning pin on the base plate is inserted into the pin hole at the bottom of the carrier to achieve precise positioning. It continues to rise until the carrier is completely separated from the positioning rod of the AGV trolley 1. AGV 1 exits the product cache component along the original route.

[0008] Another tray is picked up (the right product lifting module picks up the tray of AGV trolley 2): The AGV trolley 2 carrying the tray of product 2 moves to the waiting area of ​​the buffer component and enters the buffer component. It then moves to the previous tray receiving point (left lifting module side) to avoid interference. The rack and pinion module of the right product lifting module drives the base plate to descend; AGV trolley 2 moves to the slot on the bottom plate of the right lifting module; The rack and pinion module of the right product lifting module drives the base plate to rise. After the positioning pin is inserted into the pin hole of the carrier plate for positioning, it continues to rise, so that the carrier plate is completely separated from the AGV trolley 2. AGV trolley 2 exits along the original route.

[0009] Cartridge replacement and empty tray recovery (AGV trolley 1 recovers empty trays): AGV 1 (in an unloaded state) re-enters the buffer component waiting area; The lower cylinder assembly is raised to make room for the AGV trolley 1 to enter; AGV trolley 1, carrying the empty left product tray, enters the component and moves directly below the left lifting module tray. The cylinders of the two lifting cylinder components descend, and the standard cylinders fixed to the rodless cylinders extend to grip the empty left product tray on AGV trolley 1. After gripping, the two lifting cylinders rise, detaching the tray from AGV trolley 1. The sliders of the two rodless cylinders then begin to move the tray to the right. The left product lifting module lowers the fully loaded left product tray, positioning it on the positioning post of AGV trolley 1 before continuing to descend a short distance to detach from the lifting module tray. AGV trolley 1 then returns along the same route carrying the fully loaded tray. The rodless cylinders of the two side cylinder assemblies drive the sliders to move horizontally, transferring the gripped tray to the top of the left lifting module; the lower cylinder assembly works in conjunction to accurately place the tray on the base plate of the left lifting module. The rack and pinion module of the left lifting module drives the base plate to rise. After the positioning pin is inserted into the carrier plate pin hole for positioning, it rises to the top, completing the carrier plate buffering and waiting for subsequent processes to pick it up.

[0010] Compared with the prior art, the beneficial effects of this utility model are: Compact structure: By optimizing the layout of the lifting module and cylinder assembly, the replacement and buffering of the carrier plate can be achieved in a small space, reducing space occupation; Process optimization: The coordinated action design of the AGV trolley, lifting module, and cylinder assembly avoids interference and simplifies the pallet transfer process; Precise positioning: The positioning rod, positioning pin and carrier plate pin hole are matched to ensure the positioning accuracy of the carrier plate during the receiving, lifting and moving process; Efficiency Improvement: Enables rapid pickup, replacement, and buffering of carrier disks, adapting to the dynamic scheduling needs of automated production lines and improving overall production efficiency.
