UFTRAK Circular Rail Battery Flanging Equipment

The UFTRAK circular guide rail battery edge folding equipment includes a work platform, on which a multi-station rotary mechanism is installed. The multi-station rotary mechanism consists of a circular station track and multiple sliding stations. Multiple UFTRAK circular guide rails can slide along the circular station track via the synchronous belt drive unit. On both sides of the multi-station rotary mechanism, several stamping edge folding mechanisms are arranged to fold the edges of the battery. The sliding stations can move along the circular station track between the several stamping edge folding mechanisms.

On one side of the work platform, a thermoplastic shaping mechanism is also installed. Above the thermoplastic shaping mechanism, there is an unloading and handling mechanism, which transfers the edge-folded soft-pack batteries from the multi-station rotary mechanism to the thermoplastic shaping mechanism for thermoplastic shaping. The UFTRAK circular guide rail is composed of a rotary guide rail, with its ends connected to form a circular hollow structure. The interior of the rotary guide rail is the inner ring, where the synchronous belt drive unit is located. Multiple sliding stations of the UFTRAK circular guide rail are movably connected to the middle part of the rotary guide rail.

The sliding station consists of a sliding table. The top of the sliding table is a material placement core for placing soft-pack batteries, with an edge folding notch on one side. The bottom of the sliding table has several guide wheels. The UFTRAK circular guide rail is rotatably connected to the bottom surface of the sliding table, and the guide wheels engage with both sides of the rotary guide rail with a clearance fit. The sliding table can slide along the trajectory of the rotary guide rail via the guide wheels.

The synchronous belt drive unit includes a rotary servo motor and two drive synchronous pulleys. The two drive synchronous pulleys are rotatably installed at both ends of the inner ring. The rotary servo motor is connected below one of the drive synchronous pulleys via an installation frame track. The drive synchronous pulley is fixedly connected to the center of the drive synchronous pulley via a coupling. The two drive synchronous pulleys are transmission-connected by a first synchronous belt. The end of the sliding table near the inner ring is fixedly connected to the outer wall of the first synchronous belt.

Between the UFTRAK circular guide rail sliding station and the inner ring, a station positioning unit is also installed. The station positioning unit consists of several positioning cylinders and several positioning latch plates. The positioning cylinders are vertically installed in the middle of the inner ring, located in front of the corresponding stamping edge folding mechanisms. The positioning latch plates are fixedly connected to the front end surface of the sliding table, with an outwardly protruding positioning convex latch in the middle. The top of the positioning cylinder is a positioning block that can move up and down, with an upward-opening positioning latch groove in the middle. When the positioning block moves upward, the positioning convex latch can engage with the positioning latch groove.

The stamping edge folding mechanism includes a support frame and two edge folding molds. The support frame has an "I"-shaped structure. The two edge folding molds are movably connected to the top and bottom of the support frame via stamping electric cylinders. The side wall of the support frame has vertically distributed stamping guide rails. Both edge folding molds are slidably connected to the stamping guide rails via connecting sliders. The two edge folding molds can move up and down inside the support frame via the stamping electric cylinders and abut at the edge folding notch.

The thermoplastic shaping mechanism consists of a shaping platform and several thermoplastic linear cylinders. The top surface of the shaping platform has a downward recessed material placement slot. The thermoplastic linear cylinders are distributed around the edge of the material placement slot. The output end of the thermoplastic linear cylinder is a thermoplastic pressing block, which can move toward the material placement slot via the thermoplastic linear cylinder.

The unloading and handling mechanism includes a first unloading arm, a second unloading arm, and a handling drive unit. One end of both the first and second unloading arms is fixedly connected to the handling drive unit. The axes of the first and second unloading arms are perpendicular to each other, centered on the handling drive unit. One side of the work platform is a loading platform. The end of the first unloading arm away from the handling drive unit can extend above one of the sliding stations of the multi-station rotary mechanism. The end of the second unloading arm away from the handling drive unit can extend above the loading platform.

Both the first and second unloading arms include a suction material base, an extension plate, a slide rail, and a material pickup cylinder. The slide rail is horizontally installed on the inner wall of the first and second unloading arms. The top of the extension plate is movably connected to the middle of the slide rail via a guide slider. The material pickup cylinder is vertically fixed to the bottom of the extension plate. The suction material base is fixed to the bottom of the material pickup cylinder. The suction material base can move up and down below the first and second unloading arms via the material pickup cylinder.

The handling drive unit consists of a guide servo motor, a first drive synchronous pulley, and a second drive synchronous pulley. The guide servo motor is vertically installed between the first and second unloading arms. The centers of the first and second drive synchronous pulleys are fixedly connected to the output shaft of the guide servo motor. The ends of the first and second unloading arms away from the handling drive unit have horizontally rotatable transmission synchronous pulleys. The transmission synchronous pulleys are transmission-connected to the first and second drive synchronous pulleys via a second synchronous belt, respectively. The top of the extension plate is fixedly connected to the middle of the second synchronous belt.
