Description

Technical Field

[0001] The utility model relates to the technical field of material collecting devices, in particular to a motor rotor punching sheet feeding device. Background Art

[0002] A motor rotor is formed by stacking multiple motor rotor laminations and then wrapping them around a wire. The laminations undergo multiple processing steps during processing, often involving the transfer of the laminations from one processing device to another. Therefore, supporting feeding equipment is often required to automate the lamination processing. Existing feeding equipment is often arranged between two different processing devices. Typically, a storage area is installed on a workbench, a storage rack is used to place the stored laminations on the storage area, and a gripping mechanism is used to remove the laminations from the storage area.

[0003] Existing feeding equipment has numerous drawbacks. For example, a single storage area can typically only accommodate one stack of punched sheets. After the sheets are fed, another stack must be manually placed, forcing workers to frequently pause production to place the sheets and storage racks. Furthermore, the gripping equipment often requires a large movement space. During the gripping process, the gripper swings widely on the horizontal plane, requiring a larger horizontal surface for installation. This places higher demands on the installation location of the main punching equipment, resulting in relatively poor adaptability. Utility Model Content

DETAILED DESCRIPTION

[0027] The utility model provides a feeding device for motor rotor punching sheets, comprising a workbench 1, on which a loading device 2, a lifting device 3 and a feeding device 4 are provided. The workbench 1 is a supporting platform for the equipment, and the workbench 1 has a flat table surface, and a certain amount of accommodation space can be provided inside the lower portion thereof for convenient storage of related electrical equipment, such as motors, control equipment, etc. The loading device 2 is used to string the punching sheets into a string, forming a plurality of material strings arranged on the workbench 1. The lifting device 3 is used to slowly lift the punching sheets of each string upwards when needed so that the position of the top punching sheet is at a higher position for easy grasping. The feeding device 4 is used to remove the punching sheets from the storage rack 24 and then transfer them to the processing equipment of the next adjacent process.

[0028] The loading device 2 of the present invention includes a turntable 21 equipped with a drive device 22 that drives the turntable 21 to rotate on the workbench 1. The turntable 21 is provided with a number of positioning holes 23, on which a hopper 24 is mounted. Multiple strings of punches are placed on the turntable 21, each stacked with multiple punches. When the punches on a string are removed, the turntable 21 is rotated to rotate another hopper 24 under the feeding device 4. The worker can then remove the empty hopper 24 and replace it with a new one.

[0029] The storage rack 24 is installed on the turntable 21 in a removable and movable manner, and the size of the storage rack 24 can be replaced as needed so that punches of different sizes can be stored. The optimized storage rack 24 of the present invention includes a baffle 241, and the positioning rod 242 below the baffle 241 is inserted into the positioning hole 23 for fixation. There is a stringing rod 243 above the baffle 241, and the top of the stringing rod 243 is conical. The size of the baffle 241 is larger than the positioning hole 23, so that the storage rack 24 will not fall off after being placed on the positioning hole 23. The size of the positioning rod 242 below the baffle 241 is slightly smaller than the positioning hole 23, realizing an insert-type fixation. The stringing rod 243 can be a cylindrical round rod, and the conical shape of its top can also make it more convenient to take out and load the punches.

[0030] When removing the material storage rack 24, the positioning rod 242 of the material storage rack 24 is inserted into the positioning hole 23, and in order to improve stability, the gap between the positioning rod 242 and the positioning hole 23 is generally small, which can prevent large shaking. At this time, when the operator removes the material storage rack 24, it is necessary to use a vertical upward force to remove it. If the direction of the force used is not a completely vertical upward force, it will cause a jam, making it more difficult to remove the material storage rack 24. Therefore, an ejection cylinder 11 is provided on the workbench 1, and the ejection shaft of the ejection cylinder 11 is below the turntable 21 and directly below the positioning hole 23. When the ejection shaft of the ejection cylinder 11 moves upward, the positioning rod 242 is ejected from the positioning hole 23; a proximity switch sensor 12 is provided on the side of the ejection cylinder 11, which can determine whether there is a storage rack 24 at this position. After the ejection cylinder 11 is lifted up, it automatically returns to its original position after the storage rack 24 is taken away, making it convenient for the next storage rack 24 to be placed in this position.

[0031] The driving device 22 of the present invention can be a motor device, which includes a driving motor. The driving motor is installed inside the lower part of the workbench 1. A driving gear is installed on the rotating shaft of the driving motor. The driving gear cooperates with the reduction gear below the turntable 21. The middle part of the turntable 21 is installed on the workbench 1 through a rotating bearing.

[0032] After the punches on the material storage rack 24 are removed, the top punches continue to drop, which will be detrimental to the grabber 47 grabbing the punches. Therefore, a lifting device 3 is provided to lift the punches on the entire material storage rack 24 while keeping the material storage rack 24 stationary. A lifting claw is provided at the front end of the lifting device 3, and the lifting claw drives the material on the material storage rack 24 to move upward when the lifting device 3 moves upward. The lifting device 3 of the present invention can be a screw lifting device 3, which is vertically fixed to the workbench 1 through a bracket 31. A mounting plate is connected to the sliding module 32 of the screw lifting device 3, and a cylinder 33 is installed on the mounting plate, and a lifting claw 34 is installed on the cylinder.

[0033] When the storage rack 24 rotates to the bottom of the feeding device 4, the lifting claw of the lifting device 3 is extended and moved to the bottom of the storage rack 24 to contact the punching sheet at the bottom layer. When the grabber 47 is continuously grabbing, the lifting device 3 also continuously rises to maintain the height of the punching sheet.

[0034] The feeding device 4 of the present invention includes a feeding bracket 41, on which a rack 42 is horizontally mounted. The rack 42 is equipped with a pusher 43. A rotating gear 44 is meshed with the rack 42. A swing arm 45 is connected to the shaft of the rotating gear 44. A vertically mounted grab plate 46 is movably connected to the swing arm 45. The lower end of the grab plate 46 is mounted with a grabber 47, which is a vacuum suction cup or an electromagnet. The feeding bracket 41 is provided with a slide rail and a slider mounted on the slide rail. The grab plate 46 is movably connected to the slider. The pusher 43 can be a cylinder, which pushes the rack 42 to move left and right. For example, when moving to the right, the rotating gear 44 can also rotate. During the rotation of the rotating gear 44, the swing arm 45 can be driven to make a circular motion. When the swing arm 45 makes a circular motion, there will be a change in height on the vertical plane, so it can simultaneously drive the height and position changes of the grabbing plate 46. Since the grabbing plate 46 and the swing arm 45 are movably connected, such as hinged, the grabbing plate 46 can always maintain a vertical position and can move left and right, so that the punching sheet can be grabbed from the right to the left position, realizing the feeding function.

[0035] In the optimized solution of the present invention, a through slot 49 is provided on the slider 48, and the grabbing plate 46 passes through the through slot on the slider, so that the grabbing plate 46 can always be connected to the slider, and the slider always remains on the slide rail, which can also make the left and right movement of the grabbing plate 46 smoother and more stable.

[0036] Although the specific embodiments of the present invention are described in detail in conjunction with the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Within the scope described by the claims, various modifications and variations that can be made by those skilled in the art without creative work still fall within the scope of protection of this patent.
