[0023] Reference Figures 1 to 6 The utility model provides a feeding device for a long strip plate winding machine.

[0024] Reference Figures 4 to 6 In the first scheme of the utility model, the loading device is composed of only three parts: a frame 1, a workpiece placement frame, and a workpiece 6 handling device. The frame 1 is provided with a workpiece placement frame and a workpiece 6 handling device. The workpiece placement frame includes a front baffle frame 21, a rear baffle frame 22, a support plate 4 arranged between the front baffle frame 21 and the rear baffle frame 22, and a support drive 5 capable of driving the support plate 4 to move up and down between the front baffle frame 21 and the rear baffle frame 22. The workpiece 6 handling device includes a suction cup assembly capable of grabbing the workpiece 6 located on the baffle plate 4 and a walking mechanism capable of driving the suction cup assembly to move backward. The support drive 5 is preferably a stepper motor and a servo motor.

[0025] In this solution, the suction cup assembly includes a mounting seat 31, and a plurality of vacuum suction cups 32 arranged on the mounting seat 31, all of the vacuum suction cups 32 are arranged in a row along the left-right direction, and the walking mechanism includes a lifting seat 33, a suction cup lifting driver 34 capable of driving the lifting seat 33 to move up and down, and a transverse drive 35 arranged on the lifting seat 33, and the output end of the transverse drive 35 is connected to the mounting seat 31 to drive the suction cup assembly to move forward and backward relative to the lifting seat 33. The transverse drive 35 and the suction cup lifting driver 34 are preferably cylinders, and of course, power devices such as motors and oil cylinders can also be used.

[0026] The working principle of the scheme is to stack a stack of long strip-shaped workpieces 6 on the pallet 4; then, under the power of the above-mentioned walking mechanism, the vacuum suction cup 32 on the mounting seat 31 is moved to the top of the pallet 4; then, the vacuum suction cup 32 starts to evacuate and can grab the topmost workpiece 6; then, under the power of the above-mentioned walking mechanism, the workpiece 6 can be sent to the winding station, and after the clamps of the winding station clamp the two ends of the workpiece 6, the workpiece 6 can be wound; after the winding is completed, the processed workpiece 6 is removed, and the support driver 5 drives the pallet 4 to rise to the same distance as the thickness of the workpiece 6, and the walking mechanism moves all the vacuum suction cups 32 to the top of the workpiece 6 on the pallet 4, and then the workpiece 6 can be grabbed again and sent to the winding station for winding. Compared with the manual feeding method, the feeding device of the utility model can realize automatic feeding, with high working efficiency, which is conducive to reducing labor costs.

[0027] As a further improvement of the above solution, the workpiece placement frame also includes a positioning frame 23 located on the left or right side of the support plate 4, and the inner side of the positioning frame 23 is provided with a first positioning surface 231 capable of positioning the end surface of the workpiece 6, and a second positioning surface 232 capable of positioning the rear side surface of the workpiece 6, and an inner concave angle is formed between the first positioning surface 231 and the second positioning surface 232. When the workpiece 6 is placed on the support plate 4, the workpiece 6 can be positioned by the first positioning surface 231 and the second positioning surface 232, so that the suction cup assembly can grasp the workpiece 6 and send the workpiece 6 to a predetermined position.

[0028] Furthermore, the workpiece 6 includes two rod heads 61 and a rod body 62 located between the two rod heads 61, the width of the rod head 61 is greater than the width of the rod body 62 so that a limiting step 63 is formed between the rod head 61 and the rod body 62, and the front stop frame 21 includes at least two vertical rods, one of which can abut against the limiting step 63 to limit the workpiece 6 from moving left and right on the pallet 4.

[0029] There are two modes for the upward feeding movement of the pallet 4. Mode 1 is closed-loop control, that is, a detection device capable of detecting the highest point of the workpiece 6 stacked on the pallet 4 is set on the front baffle 21, the rear baffle 22 or other positions of the frame 1. The detection device can use a photoelectric sensor, a travel switch, a Hall induction switch and other devices to detect the position of the highest point of the workpiece pile to determine whether the pallet 4 needs to be fed upward. When the position of the highest point of the workpiece pile is too low, the detection device will send the signal to the central control chip on the frame 1, and the central control chip will send a signal to make the pallet 4 driver work and drive the pallet 4 to move upward to the appropriate position. Mode 2, since the winding time, feeding time, and the thickness of the workpiece 6 are all determined, the control program can be set to make the pallet 4 rise a certain distance at regular intervals.

[0030] Reference Figures 4 to 6 In the second scheme of the utility model, the loading device includes not only the three parts of the frame 1, the workpiece placement rack, and the workpiece 6 handling device, but also a transfer positioning and feeding device arranged on the frame 1. The transfer positioning and feeding device includes a template 7 and a two-axis walking mechanism that can drive the template 7 to move in the up and down directions and the front and back directions. The upper surface of the template 7 is provided with a positioning groove 701 for the rod body 62 of the workpiece 6 to be inserted into it. When the rod body 62 of the workpiece 6 is installed in the positioning groove 701, the two rod heads 61 of the workpiece 6 are exposed outside the positioning groove 701, and the limiting steps 63 at both ends of the workpiece 6 can respectively abut against the two end surfaces of the positioning groove 701 to limit the left and right movement of the workpiece 6 relative to the template 7.

[0031] Specifically, two groups of positioning components are arranged on the left and right of the upper surface of the template 7 . The positioning components include two limit blocks 71 . A groove is formed between the two limit blocks 71 . The two grooves together constitute a positioning groove 701 .

[0032] The working principle of this scheme is: a stack of long strip-shaped workpieces 6 are stacked on the pallet 4; then, under the power of the above-mentioned walking mechanism, the vacuum suction cup 32 on the mounting seat 31 is moved to the top of the pallet 4; then, the vacuum suction cup 32 starts to evacuate and grabs the topmost workpiece 6; then, under the power of the above-mentioned walking mechanism, the workpiece 6 can be sent to the positioning groove 701 of the template 7 to further position the workpiece 6; finally, under the power of the two-axis walking mechanism, the workpiece 6 on the template 7 can be sent to the winding station, and the clamp of the winding station clamps the two ends of the workpiece 6, and then the workpiece 6 can be wound. Compared with the first scheme, this scheme has more accurate positioning and is suitable for workpieces 6 with higher positioning requirements.

[0033] As a preferred solution of the above scheme, the two-axis walking mechanism includes a feeding frame 81, a feeding driver 82 capable of driving the feeding frame 81 to move forward and backward, and a template lifting driver 83 arranged on the feeding frame 81, and the output end of the lifting driver is connected to the template 7 to drive the template 7 to move up and down.
