Description

Technical Field

[0001] The invention relates to the technical field of resistor production, in particular to an automatic edge wrapping device for resistors. Background Art

[0002] At present, in order to increase the strength and stability of the brake resistor used in rail transit vehicles and avoid or reduce deformation, bending and breakage, it is necessary to press and wrap the resistor on both sides through metal U-shaped rods to improve the strength of the resistor and protect the resistor. At the same time, in order to avoid short-circuiting the two ends of the resistor through the wrapping rods, it is necessary to insert mica paper between the wrapping rods and the resistor to insulate the wrapping rods from the resistor. In the existing resistor wrapping process, whether the mica paper is first inserted into the wrapping rods and then the resistor is inserted between the mica papers, or the mica paper is first wrapped around the outside of the resistor and then the wrapping rod is clamped on the outside of the mica paper, it is easy to scratch the mica paper. This is because in order for the wrapping rod to effectively clamp the resistor, the U-shaped opening width of the wrapping rod is set slightly smaller than the thickness of the resistor, so that the wrapping rod is convenient for the wrapping rod to clamp the resistor under its own elastic force. However, this will cause the mica paper to be easily scratched when the wrapping rod is directly clamped and installed on the resistor, affecting the insulation effect between the wrapping rod and the resistor.

A plurality of fixed plates 422 are equidistantly fixed to one side wall of the fixed rod 421. The plurality of fixed plates 422 on the two fixed rods 421 correspond to each other one by one. An insertion portion 423 is provided at the bottom end of the fixed plate 422. The insertion portion 423 is used to insert into the edging rod. A plurality of connecting rods 415 are fixed to the other side wall of the fixed rod 421, and one end of the connecting rod 415 is rotatably connected to the driving rod 414.

[0021] In this embodiment, the output end of the cylinder 412 pushes the driving rod 414 to slide along the limiting groove 413, and the driving rod 414 squeezes the two fixed rods 421, so that the two fixed rods 421 slide away from each other along the inner wall of the fixing frame 410, so that the two fixed rods 421 deflect away from each other, and the fixed rod 421 drives the two sides of the edging rod to open through the probing portion 423 that probes into the edging rod, thereby facilitating the insertion of the resistor into the edging rod, and when the probing portion 423 is inserted into the edging rod, the mica paper is inserted into the edging rod, wherein the thickness of the probing portion 423 is less than the thickness of the inner groove of the edging rod, thereby facilitating the insertion of the probing portion 423 into the edging rod.

[0022] like Figures 4 to 6 As shown, in this embodiment, one end of the probe portion 423 is rotatably connected to the retraction rod 424, and one ends of two adjacent retraction rods 424 are rotatably connected.

Embodiment 2

[0024] like Figures 1 to 3As shown, in this embodiment, the moving frame assembly 120 includes a connecting frame 121, and the two ends of the connecting frame 121 are fixedly connected with a slide 123, the slide 123 is fixedly connected to the blanking kit 200, the slide 123 is transmission-connected to the adjacent transmission mechanism 600, the inner wall of the connecting frame 121 is fixedly connected with a linear motor 122, the output end of the linear motor 122 is transmission-connected to the bracket 500, the top sides of the bracket 100 are fixedly installed with a driving slide rail 110, the slide 123 is slidably connected to the top surface of the adjacent driving slide rail 110, the moving end of the driving slide rail 110 is fixedly connected to the adjacent slide 123, a receiving groove 510 is provided on one side of the bracket 500, and the transmission mechanism 600 includes a slide seat 1 630 and a slide seat 2 650, the slide seat 1 630 and the bracket 5 00, slide 2 650 is fixedly connected to the connected fixed frame 410, one end of slide 1 630 and slide 2 650 are fixedly connected with a gear rod 631, and a gear 640 is meshed and transmitted between the two gear rods 631, the gear 640 is rotatably connected to the inner wall of the adjacent slide 123, slide 1 630 and slide 2 650 are both slidably connected to the inner wall of the adjacent slide 123, an extension rod is fixedly connected between the other ends of the two gears 640, the output end of the linear motor 122 is fixedly connected to the extension rod, a side wall of slide 1 630 is inserted with a lifting rod 610, the bottom end of the lifting rod 610 is fixedly connected to the bracket 500, the top of the lifting rod 610 is fixedly connected with a suspension rod 620, and the end of the driving rod 414 is slidably connected between the lifting rod 610 and the suspension rod 620.

[0025] During specific implementation, the moving frame assembly 120 is driven to move left and right by driving the slide rail 110, and the two slide seats 1 630 are driven to move left and right by the linear motor 122. When the slide seat 1 630 moves left and right, the lifting rod 610 drives the bracket 500 to move left and right synchronously. Through the setting of the gear 640, the slide seat 1 630 moves left and right, and the gear 640 and the slide seat 2 650 drive the sheet separation mechanism 400 to move left and right in the opposite direction, so that the bracket 500 and the sheet separation mechanism 400 move toward each other in the left and right directions. Through the setting of the receiving groove 510, when the bracket 500 moves to the left, the receiving groove 510 moves to the bottom of the unloading kit 200, and then the unloading kit 200 is unloaded.

When the edging rod is opened by the probe part 423, the driving rod 414 drives the bracket 500 to move downward through the lifting rod 610, so that the bracket 500 avoids downward, which facilitates the downward opening of the lower side of the edging rod to avoid changes in the height position when the edging rod is opened.

[0026] like Figures 7-8As shown, in the present embodiment, the unwinding mechanism 300 comprises two end frames 310, the end frames 310 are fixedly connected to the blanking kit 200, a lifting groove 311 is provided at the top of the end frame 310, an active roller 320, a squeezing roller 330, and a guide roller 340 are rotatably connected between the two lifting grooves 311, and a servo motor 350 is fixedly installed on the outer side of one end frame 310, an output end of the servo motor 350 is transmission-connected to one end of the active roller 320, the squeezing roller 330 is located at one side of the active roller 320, the guide roller 340 is located between the lifting groove 311 and the active roller 320, a fixed blade 360 ​​is fixedly connected to one side wall of the blanking kit 200, the fixed blade 360 ​​is matched with a movable blade 370, the movable blade 370 is fixedly connected to the two fixed frames 410, and the central axes of the active roller 320 and the squeezing roller 330 are located at the same height.

[0027] During specific implementation, one end of the mica paper roll bypasses the guide roller 340 and passes between the active roller 320 and the squeezing roller 330. The squeezing roller 330 presses the mica paper against the active roller 320. When the bracket 500 and the sheeting mechanism 400 move away from each other, the servo motor 350 drives the active roller 320 to rotate, thereby releasing the mica paper downward, so that one end of the mica paper roll is released between the bracket 500 and the probe 423. When the probe 423 and the bracket 500 move toward each other, the probe 423 moves to the left, and the bracket 500 drives the edge binding rod to move to the right. When the mica paper contacts the edge binding rod and the probe 423 at the same time, the movable blade 370 cooperates with the fixed blade 360 ​​to cut off one end of the mica paper roll. The subsequent rightward movement of the probe 423 inserts the disconnected mica paper into the edge binding rod, thereby realizing the assembly of the mica paper.
