[0001] This utility model relates to a handling device, specifically a high-precision automatic forklift for feeding rolled materials. Background Technology

[0002] Many of the raw materials used in the manufacturing process of new energy batteries are in coil form. In the process of moving and handling, especially in the loading of processing equipment, conventional stacking forklifts on the market cannot be used. The loading process has high precision requirements for lifting height, precision requirements for docking with processing equipment, and other functions of the vehicle cannot be operated during the pushing of coils. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a forklift for handling coiled materials in the new energy industry, which is designed to address the defects and shortcomings of existing related equipment and features controllable lifting speed and lifting height, precise positioning, and electric material pushing.

[0004] The specific technical solution of this utility model is as follows: A high-precision automatic coil feeding forklift includes a frame assembly, a handle assembly, a hydraulic cylinder assembly, a lifting frame assembly, a support shaft assembly, and a power box. The power box is mounted on a platform at the rear of the frame assembly. The power box has a main control button and multiple function buttons. Operation requires two hands; first, the main control button is pressed, then each individual function button is pressed, ensuring that only one movement of the vehicle can be executed, preventing accidental operation. Electric drive wheels and balance wheels are respectively mounted on both sides of the bottom rear of the frame assembly. The handle assembly is connected to the electric drive wheels, and the steering of the drive wheels is directly driven by rotating the control handle. Two masts are located at the front of the frame assembly. Casters are mounted at the front of the masts, and POM guide plates are mounted on the outer sides of the masts, facilitating the vehicle's entry into the guide groove of the processing equipment during docking, ensuring the vehicle and processing equipment are aligned. The chassis assembly has a cylinder support at its bottom, on which the cylinder assembly is mounted. C-shaped masts are located on either side of the cylinder support. A touchscreen is mounted on one side of each C-shaped mast via a universal bracket. The touchscreen can move significantly left and right and tilt up and down to accommodate operators of different heights. This touchscreen operation is more convenient when the vehicle is docked with processing equipment. The two C-shaped masts are connected at the middle by a load-bearing beam. The upper part of the cylinder assembly is fixed to the load-bearing beam with U-bolts. The bottom end connector of the cylinder is connected to one end of a hydraulic hose, the other end of which extends into the power box and connects to a dual-speed lifting valve block. The dual-speed lifting valve block is connected to a hydraulic pump station via a hydraulic hose. Two overflow valves with different inner core diameters are installed on the dual-speed lifting valve block to control the up and down movement speed of the lifting piston rod. The cylinder assembly is connected to the lifting frame assembly via a chain, and a support shaft assembly is mounted at the front end of the lifting frame assembly.

[0005] Furthermore, the top of the hydraulic cylinder assembly is equipped with a lifting rod joint, the upper part of which is equipped with a sprocket shaft, and each end of the sprocket shaft is equipped with a sprocket, on which a chain is clamped.

[0006] Furthermore, one end of the chain is connected to the chain bolt fixed on the load-bearing beam via chain plates and locking plates, while the other end is connected to the lifting frame assembly via buckles and locking plates. The lifting frame assembly is equipped with two rollers on both sides, which fit into the C-shaped gatepost grooves and can roll up and down along the height direction of the C-shaped gatepost.

[0007] Furthermore, the support shaft assembly includes a support shaft, with a pusher sleeve fitted over it. The bottom of the support shaft is hollow, housing a linear track assembly. This linear track assembly has a lead screw and nut, on which a pusher sleeve fixing plate is mounted. The pusher sleeve fixing plate and the pusher sleeve are fixedly connected. Several bearings protruding from the top of the support shaft are mounted on its top surface, making the pushing process more effortless. An electromagnetic pin is installed at the top front end of the support shaft to prevent the material roll from detaching from the shaft. A diffuse reflection switch is installed on the side of the front end of the support shaft. When the switch illuminates the equipment and activates, the vehicle's movement speed automatically adjusts to a slower speed, preventing collisions due to misoperation. A positioning block is installed at the head of the support shaft to ensure that the support shaft does not damage the processing equipment during docking. A proximity switch is centrally mounted on the positioning block. Once the switch senses that docking with the equipment is in place, the loading and unloading of the material roll can begin.

[0008] Furthermore, a battery housing is located at the bottom of the power box, and the battery housing has a side pull-out cover. The side pull-out cover is used to install lithium batteries. The side pull-out cover is connected to the battery housing by a latch, and a certain amount of force is required when inserting or pulling it out.

[0009] Furthermore, the bottom of the C-shaped door pillar is equipped with a pull-rope sensor. The steel wire rope of the pull-rope sensor is connected to the lifting frame assembly, and the signal line on the sensor is connected to the PLC programmable controller in the power box. This can control the change in vertical height difference of 0.mm, making the docking of the vehicle with the processing equipment more precise.

[0010] The beneficial effects of this utility model are: it can quickly and accurately handle rolled materials, and has high precision in docking with equipment, which greatly reduces the labor intensity of employees, improves work efficiency, and reduces operational risks.

The handle assembly 2 is connected to the electric drive wheels 7, and the steering of the drive wheels 7 is directly driven by rotating the control handle 9. Two masts 28 are located at the front of the frame assembly 1. Casters 6 are mounted on the front of the masts 38, and POM guide plates 10 are mounted on the outer side of the masts 30. These guide plates facilitate the vehicle's entry into the guide slots of the processing equipment during docking, ensuring proper alignment between the vehicle and the processing equipment. The bottom of the frame assembly 1 is also equipped with a cylinder support 31, on which the cylinder assembly 3 is mounted. On both sides of the cylinder support 31, the frame assembly 1 is also equipped with C-shaped portal pillars 32. A touchscreen 25 is mounted on one side of each C-shaped portal pillar 32 via a universal bracket 26. The touchscreen 25 can move significantly left and right and tilt up and down via the universal bracket 26 to accommodate operators of different heights. When the vehicle is docked with processing equipment, operation via the touchscreen is more convenient. The two C-shaped portal pillars 32 are connected in the middle by a load-bearing central beam 33. The upper part of the cylinder assembly 3 is fixed to the load-bearing central beam 33 by U-bolts 11. The bottom end connector of the cylinder assembly 3 is connected and fixed to one end of a hydraulic oil pipe 27. The other end of the hydraulic oil pipe 27 extends into the power box 24 and connects to a dual-speed lifting valve block. The dual-speed lifting valve block is connected to a hydraulic pump station via a hydraulic oil pipe. Two overflow valves with different inner core diameters are installed on the dual-speed lifting valve block to control the up and down movement speed of the lifting piston rod. The hydraulic cylinder assembly 3 is connected to the lifting frame assembly 4 via chain 15, and the front end of the lifting frame assembly 4 is equipped with a support shaft assembly 5.

[0016] The top of the hydraulic cylinder assembly 3 is equipped with a lifting rod joint 12, the upper part of the lifting rod joint 12 is equipped with a sprocket shaft 13, and each end of the sprocket shaft 13 is equipped with a sprocket 14, and a chain 15 is clamped on the sprocket 14.

[0017] One end of the chain 15 is connected to the chain bolt fixed on the load-bearing beam 33 via chain plates and locking plates, and the other end is connected to the lifting frame assembly 4 via buckles and locking plates. The lifting frame assembly 4 is equipped with two rollers on both sides. The rollers are fitted into the grooves of the C-shaped gatepost 32 and can roll up and down along the height direction of the C-shaped gatepost.

[0018] The support shaft assembly 5 includes a support shaft 34, with a pusher sleeve 18 fitted around it. The bottom of the support shaft 34 is hollow, housing a linear track assembly 16. The linear track assembly 16 has a lead screw nut 35, on which a pusher sleeve fixing plate 17 is mounted. The pusher sleeve fixing plate 17 and the pusher sleeve 18 are fixedly connected. Several bearings 19 protruding from the top of the support shaft 34 are mounted on its top surface, making the pushing process more effortless. An electromagnetic pin 20 is mounted at the top front end of the support shaft 34 to prevent the material roll from detaching from the shaft. A diffuse reflection switch 21 is mounted on the side front end of the support shaft 34. When the switch illuminates the equipment and activates, the vehicle's movement speed automatically adjusts to a slower speed, preventing collisions due to misoperation. A positioning block 22 is installed at the head of the support shaft 34 to ensure that the processing equipment is not damaged during docking. The positioning block 22 is centrally equipped with a proximity switch 23. When the switch senses that it is in place with the equipment, the loading and unloading of the material roll can be carried out.

[0019] The bottom of the power box 24 is equipped with a battery housing, which has a side pull-out cover 28. The side pull-out cover 28 is used to install lithium batteries.

It can control the change of vertical height difference of 0.5mm, making the docking of the vehicle with the processing equipment more precise.

[0021] During operation, the vehicle is electrically driven by the control handle 9 and guided through the guide plate 10 into the guide groove of the processing equipment to align with the equipment. The vehicle continues to move forward. When the diffuse reflection switch 21 senses the equipment, the PLC controller automatically adjusts the vehicle's speed to a slow, meandering pace until the proximity switch 23 in the middle of the docking positioning block 22 senses that the vehicle is properly docked with the equipment. At this point, the PLC controller disconnects the vehicle's lifting function signal, and the relevant function buttons become ineffective. Only the electromagnetic pin 20 can be raised or lowered, and the pusher sleeve 18 can be moved forward or backward. After the material roll is loaded or unloaded, the electromagnetic pin 20 is raised, and the vehicle is electrically driven backward at a slow pace by the control handle 9 until the diffuse reflection switch 21 ceases to function. Only then can the vehicle quickly leave the processing equipment.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
