Description

Technical Field

[0001] This utility model belongs to the field of automation devices for motor manufacturing equipment, and particularly relates to an automatic loading and unloading mechanism for stator production. Background Technology

[0002] The motor manufacturing industry has always been labor-intensive. Due to the special nature of its products, automated production has been difficult to achieve. Stator coating and varnishing are mostly done using semi-automatic machines or entirely manually, making automated material handling impossible. However, both semi-automatic and manual production methods are costly, labor-intensive, and inefficient. With rising labor costs and a widening labor shortage, these methods are increasingly unable to meet the needs of some motor manufacturers. Automated material handling systems, which integrate material handling devices with production lines, have become popular due to their high degree of automation, high efficiency, high accuracy, and low cost of modifying existing production lines. Market demands for reduced labor costs and increased production efficiency necessitate automated material handling, requiring solutions to the stator loading, unloading, transfer, and securing issues. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic stator loading and unloading mechanism that is simple in structure, highly stable in transfer and fixing, and accurately positioned during stator production. This mechanism enables the automatic transfer and fixing of the stator to work in a timely and effective manner with automated equipment, ensuring automated stator loading and unloading, and improving production efficiency and safety.

[0004] The purpose of this utility model is achieved through the following technical solution: an automatic stator loading and unloading mechanism, including a mounting plate and rodless cylinder and positioning cylinder assembly mounted under the mounting plate. The mounting plate is provided with a transfer slide rail, on which a transfer plate is mounted. The transfer plate is provided with a guide rail, a pusher slide rail, a transfer bracket and a screw drive assembly. A fixed plate is mounted at one end of the transfer plate, and a servo motor is mounted on the fixed plate. The output shaft of the servo motor is connected to the screw drive assembly. A pusher bracket is mounted on the pusher slide rail and is connected to the moving end of the screw drive assembly. Multiple rollers are evenly distributed along the upper edge of the transfer bracket, and a tray plate and clamps are placed on the rollers. A positioning assembly is also installed on the moving end of the pusher bracket and the screw drive assembly for positioning the transfer plate during movement. A rodless cylinder drives the transfer plate to move along the transfer slide rail to the material picking position. The positioning cylinder assembly cooperates with the fixed plate to limit the transfer plate. The pallet and fixture (including the stator) are conveyed to the next station via rollers. The positioning assembly assists in positioning the pallet. The servo motor drives the lead screw transmission assembly to move the pusher bracket along the pusher slide rail to move the pallet and fixture, pushing the pallet to the designated station. After loading and unloading are completed, the positioning cylinder assembly releases the pusher bracket to reset. The rodless cylinder drives the transfer plate back to the initial position. The cycle continues. The positioning assembly and positioning cylinder assembly ensure the positioning accuracy of each station. The whole system realizes automatic conveying, positioning and loading / unloading of stator pallets, replacing manual operation and improving the automation level and production efficiency of the stator assembly line.

[0005] Preferably, the lead screw drive assembly includes a lead screw, a lead screw nut, and a lead screw support. The lead screw drive assembly is mounted on the transfer plate via the lead screw support. The lead screw nut is sleeved on the lead screw and forms a threaded transmission engagement. The lead screw nut serves as the moving end and is fixedly connected to the pusher bracket and the positioning assembly. The output shaft of the servo motor is connected to one end of the lead screw via a coupling.

[0006] Preferably, the rollers are rotatably mounted on the upper end of the transfer bracket via bearings, and the spacing between two adjacent rollers is adapted to the bottom support structure of the pallet; multiple guide rollers are provided on both sides of the transfer plate to cooperate with guide rails for guidance and positioning.

[0007] Preferably, the positioning cylinder assembly includes at least two symmetrically arranged on both sides of the mounting plate, the piston rod end of the positioning cylinder is provided with a positioning block, and the mounting plate is provided with a corresponding protrusion hole so that the positioning block on the positioning cylinder assembly cooperates with the fixing plate to limit the position of the transfer plate.

[0008] Compared with the prior art, the effects and benefits of this utility model are as follows: (1) Precise and efficient driving: The rodless cylinder drives the transfer plate to quickly switch the work position, and the servo motor and the screw transmission assembly realize stepless speed regulation of the pushing action and accurate positioning; (2) Stable stator conveying of this utility model: The roller distribution design of the transfer bracket reduces friction, and the positioning assembly and guide rail limit the position to avoid pallet deviation; (3) Reliable structure of the automatic stator loading and unloading mechanism of this utility model: Modular assembly (such as positioning cylinder assembly and screw assembly) facilitates maintenance, the positioning assembly and cylinder dual positioning ensure the operation accuracy, the structure design is reasonable, the guide rail slider and roller are used to achieve smooth conveying, the overall layout is compact, the disassembly and maintenance are convenient, and it is suitable for the working conditions of stator batch production.
